Properties and parameters for effective laser hair removal: A review

Because some people seek consultations for the removal of unwanted body hair, a permanent, safe, and non-invasive method of hair removal is needed. Laser hair removal has been a popular cosmetic procedure. It is a monthly treatment that may take up to ten sessions for permanent results. However, its efficacy varies due to the patient’s biological skin hair traits, the adjustment of the optimal parameters of the laser, and the protocols. The purpose of this review is to discuss the properties and parameters employed for laser hair removal. Once parameters for laser hair removal have been optimized, this treatment offers an effective and permanent solution for unwanted body hair.

Contribution of Soil Type to Quantity and Nutritional Value of Grass Species on the South African Highveld

The biggest threat to cattle production in most South African communal areas is poor management of grazing, which negatively affects vegetation and soil structures. This study was conducted to assess the spatial variation of grass species density, production potential and quality in Breyten (Hutton soil type), Davel (Avalon soil type), and Wesselton (Clovelly soil type) communal rangelands in the highveld region of Mpumalanga province. Three 100 m transects per grazing area, placed at 50 m intervals (0, 50, and 100 m) were used to collect soil samples at 200 mm depth. A 100 m permanent line point method, replicated three times (50 m apart) per site, was used to identify and collect grass species samples. Grass species were classified according to life form, palatability, ecological status, and abundance. Grasses species were also harvested for chemical composition and in vitro ruminal dry matter degradability determination. Soils from the study areas had an acidic pH range (3.5–4.5). Hutton soil had the highest (p < 0.05) nitrate (N-NO3) concentration (0.770 mg/kg) compared to Clovelly (0.030 mg/kg) and Avalon (0.533 mg/kg) soil types. Thirty-one grass species composed of 28 turf perennials, two weak perennials and one perennial creeping grass were identified across the study areas. About 16% of identified grass species were classified as highly palatable, 39% as moderately palatable, and 32% as unpalatable. Across all the soil types, Digitaria eriantha had the highest (p < 0.05) crude protein (CP) (106.5 g/kg DM) content when compared to other grass species. In the Avalon soil type, D. eriantha had the lowest (p < 0.05) neutral detergent fiber (NDF) (696.4 g/kg DM). Across all soils, D. eriantha, Aristida congesta, Eragrostis curvula, Eragrostis gummiflua, and Eragrostis plana grasses had the same (p > 0.05) 48-h in vitro ruminal dry matter degradability Hutton soil had a higher proportion of common and dominant grass species as well as more palatable species with higher crude protein content than Avalon and Clovelly soils. However, for all three rangelands, there is a need for supplementary feeding to enhance the production efficiency of livestock given that the nutritive value of grasses was low.

A quick fault location and isolation method for distribution network based on adaptive reclosing

Feeder automation is important to improve the reliability of power supply for distribution network. Existing voltage-time feeder automation scheme exists the problems of long fault processing time and the upstream switches of the fault point need to tolerate fault current twice and the upstream sections need to experience two short time power outage. In this paper, a quick fault location and isolation method for distribution network based on adaptive reclosing is proposed. Three key technologies of the strategy are introduced, including a phase segregated switch of the distribution network based on the permanent magnet operating structure, the phase selector based on transient current characteristics, and the temporary fault and permanent fault identification method based on the power frequency voltage characteristics. The proposed strategy can avoid the second impact on upstream switches and power-off of the upstream section in case of the permanent fault and can effectively shorten the fault processing time.

Association between the place of abortion and post-abortion contraceptive adoption and continuation: the case of India

The unmet need for contraception is documented as a significant determinant of unintended pregnancies and high number of induced abortions. The period immediately after an abortion is recognised as a unique opportunity to offer contraceptive services. This paper explores the association between place of abortion and women's post-abortion contraceptive behaviour. The reproductive calendar data from the National Family Health Survey (NFHS-4) (2015–16) was used for this study. Multinomial logistic regression models were used to understand factors associated with post-abortion method choices. Single decrement life-tables were built to examine rates of contraceptive discontinuation and proportional hazard models were employed to examine probability and correlates of method discontinuation. About 20% of women who underwent an abortion adopted a contraceptive method by the end of one month following an abortion. The decision to choose methods like sterilisation or intrauterine contraceptive devices (IUCDs) was associated with the place of abortion, past contraceptive behaviour, number and sex of surviving children at the time of abortion, mass media exposure, and time of the abortion. Compared to women who underwent an abortion at private health facilities, women who sought abortion at public health facilities were more likely to choose permanent methods or IUCDs. Furthermore, women who opted for an IUCD were less likely to discontinue the method compared to those using short-acting modern methods. The lack of post-abortion contraceptive choices for women is evident in the low uptake of post-abortion contraceptives in private facilities and the predominant promotion of permanent methods and IUCDs in public health facilities.

Design of quasi-axisymmetric stellarators with variable-thickness perpendicular permanent magnets based on a two-step magnet design strategy

A new method for designing stellarators with variable-thickness perpendicular permanent magnets has been developed, based on a two-step magnet design strategy that we previously proposed for designing stellarators with standardized magnet blocks. Our design strategy uses a ‘local compensation’ method to obtain an initial magnet design and a ‘global fine-tuning’ method to further optimize the initial design. The new method is compared to the previously proposed Fourier decomposition method, and the results indicate that this new method can yield a similar magnet design for an N fp = 2 quasi-axisymmetric stellarator at a lower computational cost. High accuracy is achieved, as demonstrated by a normal magnetic field square on the plasma surface of , a maximum residual of for a ∼1 T total field, and a flux-surface-averaged residual B n of relative to the total field. Furthermore, the new method can automatically yield a magnet design with large areas of continuous vacancies for ports and plasma access, which is more flexible than the Fourier decomposition method. These results indicate that the new method is robust and effective when used to design stellarators with variable-thickness perpendicular permanent magnets, and, most importantly, that the two-step magnet design strategy has great potential to develop permanent magnet design methods suitable for various magnet layouts.

Family Planning: Popular Methods and Their Effects

The number of children directly affects the health and nutritional status of mother. For a healthy child, the mother should be healthy and this could be possible with planned pregnancies or avoiding unwanted pregnancies by use of family planning methods. The present study was undertaken to investigate the methods of family planning used and their effect on the health of a woman. The study was carried out in the city of Varanasi in Uttar Pradesh, India. The study was cross-sectional and comprised of 220 married women aged 25-40 years, who voluntarily agreed to participate in the study. The respondents were randomly selected, with the exclusion criteria for unmarried, widow, divorcee women, or those who were not living with their husbands. The results showed that the respondents were aware of the family planning concept. The best source of information regarding family planning was media (36.36%); and the maximum of them preferred the permanent method (40.45%) as the method of contraception. Only a few of them (38.64%) were aware of government policies and plans related to family planning. 26.37% of respondents felt that they were having health problems by using contraceptive methods. The health problems were observed among the respondents using Intra-Uterine Devices (58.49%) and oral contraceptive pills (41.51%). Age and nutritional status of the mother during conception both contribute to the health and nutritional status of the child. Government should establish policies related to exposure of married couples towards family planning methods along with easy access to family planning methods especially for the lower class people. Also, more in-depth study of the use and awareness of family planning methods should be done as it is essential for the well-being of the mother, child, and family and even society as a whole.

Tubectomy of Pregnant and Non-pregnant Female Balinese Macaques (Macaca Fascicularis) With Post-operative Monitoring.

Worldwide, primates, and humans increasingly share habitats and often enter in conflict when primates thrive in human-dominated environments, calling for special management measures. Reproductive control is increasingly used to manage population growth but very few monitoring data are available. Therefore, the efficiency and implications of such programs require a careful examination. In the context of a contraception program in wild female long-tailed macaques in Ubud, Bali, conducted over four successive campaigns between 2017 and 2019, including 140 females (i.e., 41.9% of the reproductive females of the population in 2019), modifications of an endoscopic tubectomy procedure, a permanent sterilization method, clinical evaluation of this method, and the post-operative monitoring results of the neutered females after release are described. This surgical approach was applicable for pregnant females: 28.6% of the treated females were pregnant at the time of the surgery. The procedure used a single lateral port to reach and cauterize both oviducts in non-pregnant as well as in early to mid-term pregnant females. Pregnant females nearer to term required a second lateral port to access both oviducts masked by the size of the gravid uterus. Moreover, bipolar thermocauterization was utilized successfully without resection to realize the tubectomy. The average duration of the laparoscopic surgery was 14 min for non-pregnant females and 22 min for pregnant females. Animals were released 3 h 22 min in average following their capture. This short holding time, recommended for free-ranging primates, was made possible by the minimal invasiveness of the sterilization approach. A laparoscopic post-operative evaluation conducted on two patients during the following campaign confirmed that the oviducts were definitely disrupted and no longer patent. Moreover, no new pregnancies in sterilized females were recorded during the 3-year observation period. The survival rate of the treated females 6 months after sterilization was high (96.3%) with no major post-operative complications clinically recorded. Among females that were pregnant during surgery, 81.1% were confirmed to experience term delivery. This study demonstrates the safety and efficiency of endoscopic tubectomy, even for pregnant females, as a mean of wild macaques' population control.

Retrosplenial cortex inactivation during retrieval, but not encoding, impairs remotely acquired auditory fear conditioning in male rats

Prior studies with permanent lesion methods have demonstrated a role for the retrosplenial cortex (RSC) in the retrieval of remotely, but not recently, acquired delay fear conditioning. To extend the generalizability of these prior findings, the present experiments used chemogenetics to temporarily inactivate the RSC during either retrieval or encoding of delay auditory fear conditioning. Inactivation of the RSC at the time of test impaired retrieval of a remotely conditioned auditory cue, but not a recently conditioned one. In addition, inactivation of the RSC during encoding had no impact on freezing during later retrieval testing for both a remotely and recently conditioned auditory cue. These findings indicate that the RSC contributes to the retrieval, but not encoding, of remotely acquired auditory fear conditioning, and suggest it has less of a role in both retrieval and encoding of recently acquired auditory fear conditioning.

Modern contraceptive use among women in need of family planning in India: an analysis of the inequalities related to the mix of methods used

ObjectiveTo evaluate the type of contraceptives used by women in need of family planning in India and the inequalities associated with that use according to women's age, education, wealth, subnational region of residence and empowerment level.MethodsUsing data from the Indian National Family and Health Survey-4 (2015–2016), we evaluated the proportion of partnered women aged 15–49 years with demand for family planning satisfied (DFPS) with modern contraceptive methods. We also explored the share of each type of contraception [short- (e.g., condom, pill) and long-acting (i.e., IUD) reversible contraceptives and permanent methods] and related inequalities.ResultsThe majority (71.8%; 95% CI 71.4–72.2) of women in need of contraception were using a modern method, most (76.1%) in the form of female sterilization. Condom and contraceptive pill were the second and third most frequently used methods (11.8% and 8.5%, respectively); only 3.2% reported IUD. There was a nearly linear exchange from short-acting to permanent contraceptive methods as women aged. Women in the poorest wealth quintile had DFPS with modern methods at least 10 percentage points lower than other women. We observed wide geographic variation in DFPS with modern contraceptives, ranging from 23.6% (95% CI 22.1–25.2) in Manipur to 93.6% (95% CI 92.8–94.3) in Andhra Pradesh. Women with more accepting attitudes towards domestic violence and lower levels of social independence had higher DFPS with modern methods but also had higher reliance on permanent methods. Among sterilized women, 43.2% (95% CI 42.7–43.7) were sterilized before age 25, 61.5% (95% CI 61.0–62.1) received monetary compensation for sterilization, and 20.8% (95% CI 20.3–21.3) were not informed that sterilization prevented future pregnancies.ConclusionIndian family planning policy should prioritize women-centered care, making reversible contraceptive methods widely available and promoted.

Quality of Care in Family Planning Services: Differences Between Formal and Informal Settlements of Kira Municipality, Uganda.

Background: Quality of care (QoC) of family planning (FP) affects contraceptive use, and it varies across types of urban settlement. This study assesses the difference in service delivery point (SDP) structural and process factors between formal and informal urban settlements, and the opinion of the client on the QoC in informal settlements. This is useful in creating an evidence base to advocate for better quality services for the most vulnerable in society.Methods: This was a cross-sectional survey that included SDPs of Kira municipality in Wakiso district, Uganda. Data were collected from all the service points in Kira municipality with the caretakers consented. In addition, using multi-stage sampling, 626 women of reproductive age (15–49 years) who lived in the informal settlements of Kira municipality were interviewed. Data were collected using structured questionnaires, descriptive analysis was carried out in Stata version 14.0, and Chi-square and t-tests were used to compare the informal with the formal settlements.Results: Formal settlements generally had more higher-level SDPs compared to informal settlements (value of p < 0.001). SDPs in the formal settlements provided more FP methods and had more community health workers (CHW) to support their work. Also, SDPs in the formal settlements were more likely to have long-term FP methods available and more likely to have trained personnel to insert and remove implants and IUDs compared to those in informal settlements. Additionally, more SDPs in the formal settlements provided counseling for permanent, long-term, and short-term FP methods. Of the 626 interviewed women, most of the women (68.6%) reported that they would not return to the previous FP provider or refer a friend to the same provider (72.7%).Conclusions: There is a lower quality FP services in the informal settlements with a commensurable effect on the client satisfaction with the services. Therefore, improving the quality of FP services in informal settlements should be a top priority. Improved quality of services could act as a motivation to increase the uptake of modern contraceptives in such settings.

Investment and Decapitalization in the Fishing Industry: The Case of the Spanish Crustacean Freezer Trawler Fleet

The objective of this work is to estimate the capital stock invested in the Spanish freezer trawler fleet dedicated to the capture of crustaceans on the African coast, for the period from 1964 to 2019. The importance of having methods for the correct measurement of the capital invested in a fishing fleet is to be able to express in monetary terms the excess catch capacity, which is a signal of overexploitation of a fishery, that is, the fleet operates at a level of effort or capacity higher than the minimum amount required to capture the desired quantity at the lowest possible cost. Following a methodology based on the permanent inventory method, we obtained a model that explains the construction value of a fishing vessel as a function of its technical characteristics. The market value in successive sales was estimated as a function of the construction value, the age of vessel and other variables. In this way, we estimated the value that the market assigns to the possible increases in individual fishing capacity and the decrease in value derived from the technical obsolescence of the vessels. Finally, we calculated the gross and net investment series and net capital stock.

Assessing Wealth-Related Inequalities in Demand for Family Planning Satisfied in 43 African Countries.

Background: Around 80% of the African population lives in urban areas, and a rapid urbanization is observed in almost all countries. Urban poverty has been linked to several sexual and reproductive health risks, including high levels of unintended pregnancies. We aim to investigate wealth inequalities in demand for family planning satisfied with modern methods (mDFPS) among women living in urban areas from African countries.Methods: We used data from 43 national health surveys carried out since 2010 to assess wealth inequalities in mDFPS. mDFPS and the share of modern contraceptive use were stratified by groups of household wealth. We also assessed the ecological relationship between the proportion of urban population living in informal settlements and both mDFPS and inequalities in coverage.Results: mDFPS among urban women ranged from 27% (95% CI: 23–31%) in Chad to 87% (95% CI: 84–89%) in Eswatini. We found significant inequalities in mDFPS with lower coverage among the poorest women in most countries. In North Africa, inequalities in mDFPS were identified only in Sudan, where coverage ranged between 7% (95% CI: 3–15%) among the poorest and 52% (95% CI: 49–56%) among the wealthiest. The largest gap in the Eastern and Southern African was found in Angola; 6% (95% CI: 3–11%) among the poorest and 46% (95% CI: 41–51%) among the wealthiest. In West and Central Africa, large gaps were found for almost all countries, especially in Central African Republic, where mDFPS was 11% (95% CI: 7–18%) among the poorest and 47% (95% CI: 41–53%) among the wealthiest. Inequalities by type of method were also observed for urban poor, with an overall pattern of lower use of long-acting and permanent methods. Our ecological analyses showed that the higher the proportion of the population living in informal settlements, the lower the mDFPS and the higher the inequalities.Conclusion: Our results rise the need for more focus on the urban-poorer women by public policies and programs. Future interventions developed by national governments and international organizations should consider the interconnection between urbanization, poverty, and reproductive health.

Association between empowerment factors and the utilization of long-acting and permanent contraceptive methods among married women in Indonesia

Background and purpose: The use of long-acting and permanent methods (LAPMs) of contraception becomes one of the government’s efforts to ensure the continuity of family planning program. Factors associated with the LAPMs use can be contingent upon the study context or setting that includes socio-demographic, social and cultural norms, and women empowerment factors. This study aims to examine the associations between women empowerment and the LAPMs use.Methods: This was a cross-sectional study involving 97,316 records of married women aged 15-49 years, retrieved from three rounds of the Indonesia Demographic and Health Survey/IDHS (2007, 2012, and 2017). The dependent variable is the LAPMs use, whereas the main independent variables were women empowerment factors (i.e., educational level, occupational status, participation in household decision-making, attitude toward wife-beating). Adjusted associations between women empowerment and the LAMPs use were examined using binary logistic regression by controlling the influence of socio-demographic variables as potential confounders.Results: About half of women in this study were 35-49 years old and completed primary education. Education level was found to be positively associated with the use of LAPMs. Working women increased the likelihood of using LAPMs by 1.10 (95%CI: 1.03-1.17) times. In addition, those who approved for being beaten by their husband in any circumstance were less likely to use LAPMs (OR=0.91; 95%CI: 0.86-0.97). However, participation in household decision-making was not associated with the LAMPs use.Conclusion: Women empowerment factors that included educational level, occupational status, and the attitude toward wife-beating were associated with the use of LAPMs among Indonesian married women. Therefore, improving women empowerment by increasing women’s educational level, participation in labor force, and reducing women’s vulnerability to domestic violence can increase the uptake of LAPMs.

Gambaran Tingkat Pengetahuan Dan Sikap Ibu Tentang Trauma Gigi Permanen Pada Anak Usia 8-12 Tahun : Kajian pada Ibu dari Murid SD Nabawi Islamic School, Kota Jakarta Timur (Laporan Kasus)

Background: Children's dental trauma mostly occurs in the maxillary anterior teeth, and falls, sports, traffic accidents, etc. can cause dental trauma. Generally speaking, children experience dental trauma when they are 8-12 years old. Therefore, dental trauma is a serious problem that often occurs in children and requires special attention from parents, especially mothers. Objective: To understand mother’s knowledge and attitudes towards children’s permanent tooth trauma Method: A descriptive observational cross-sectional design was adopted to conduct a survey of 70 respondents. The data was collected using a questionnaire, including 21 questions, tested validity and reliability. The research data is presented in the form of a frequency distribution table. Results: The adequate degree of mother's description of children's dental trauma knowledge was 75.7%, less than 15.7%, and less than 8,6%. In terms of attitude, 44.3% of the respondents hold a high attitude, and 55.7% of the respondents hold a low attitude. Conclusion: Most mothers have a high understanding of dental trauma, but there are still many mothers who have a low attitude towards dental trauma.

Comparing options for females seeking permanent contraception in high resource countries: a systematic review

BackgroundMultiple options for permanent or long-acting contraception are available, each with adverse effects and benefits. People seeking to end their fertility, and their healthcare providers, need a comprehensive comparison of methods to support their decision-making. Permanent contraceptive methods should be compared with long-acting methods that have similar effectiveness and lower anticipated adverse effects, such as the levonorgestrel-releasing intrauterine contraception (LNG-IUC). We aimed to understand the comparability of options for people seeking to end their fertility, using high-quality studies. We sought studies comparing laparoscopic tubal ligation, hysteroscopic tubal occlusion, bilateral salpingectomy, and insertion of the LNG-IUC, for effectiveness, adverse events, tolerability, patient recovery, non-contraceptive benefits, and healthcare system costs among females in high resource countries seeking to permanently avoid conception.MethodsWe followed PRISMA guidelines, searched EMBASE, Pubmed (Medline), Web of Science, and screened retrieved articles to identify additional studies. We extracted data on population, interventions, outcomes, follow-up, health system costs, and study funding source. We used the Newcastle–Ottawa Scale to assess risk of bias and excluded studies with medium–high risk of bias (NOS < 7). Due to considerable heterogeneity, we performed a narrative synthesis.ResultsOur search identified 6,612 articles. RG, BV, BC independently reviewed titles and abstracts for relevance. We reviewed the full text of 154 studies, yielding 34 studies which met inclusion criteria. We excluded 10 studies with medium–high risk of bias, retaining 24 in our synthesis. Most studies compared hysteroscopic tubal occlusion and/or laparoscopic tubal ligation. Most comparisons reported on effectiveness and adverse events; fewer reported tolerability, patient recovery, non-contraceptive benefits, and/or healthcare system costs. No comparisons reported accessibility, eligibility, or follow-up required. We found inconclusive evidence comparing the effectiveness of hysteroscopic tubal occlusion to laparoscopic tubal ligation. All studies reported adverse events. All forms of tubal interruption reported a protective effect against cancers. Tolerability appeared greater among tubal ligation patients compared to hysteroscopic tubal occlusion patients. No high-quality studies included the LNG-IUC.ConclusionsStudies are needed to directly compare surgical forms of permanent contraception, such as tubal ligation or removal, with alternative options, such as intrauterine contraception to support decision-making.Systematic review registrationPROSPERO [CRD42016038254].

Mass media exposure and use of reversible modern contraceptives among married women in India: An analysis of the NFHS 2015-16 data.

Since the inception of the National Programme for Family Planning, messages on family planning (FP) have been promoted across India using different mass media platforms. Mass media plays an important role in disseminating important information among the masses, such as how reversible modern methods give women more reproductive choices than opting for permanent methods that limit their child-bearing capacity. Mass media can provide a continuous flow of information and motivation to deter women from discontinuing the methods they have opted for. However, very few studies have been conducted on this issue, especially using recently available data. This study particularly focuses on exposure to mass media and the use of reversible modern methods of family planning among married women in India. The data for this study was obtained from the National Family Health Survey (2015–16) on currently married women aged 15–49 years. The association of reversible modern method use with media exposure variables was examined, controlling for a set of independent variables from multiple levels—individual, district, state, and region. The findings from this study showed that television was the most important medium for disseminating information on FP among married women in India. Spatial analysis revealed that some districts in the north, parts of the northeast, and Kerala in South India lacked any television exposure. The results from the decomposition analysis showed that mass media exposure was associated with a 14% increase in the use of reversible modern methods. Results from the multilevel analyses showed that exposure to TV along with other media (AOR 1.57 95% CI 1.49–1.65) and exposure to FP messages through different media (AOR 1.22 95% CI 1.12–1.32) had a significant positive effect on the use of reversible modern methods even when various individual, district, state, and regional-level factors were controlled. The findings of this paper provide evidence supporting the use of mass media to promote and increase awareness of voluntary contraceptive use in India. An increase in mass media exposure coupled with improvement in coverage and services of the FP program can significantly increase the use of reversible modern methods in a cost-effective yet efficient manner among women in need of FP services.

Orthogonal Optimal Design of Multiple Parameters of a Magnetically Controlled Capsule Robot.

Magnetically controlled capsule robots are predominantly used in the diagnosis and treatment of the human gastrointestinal tract. In this study, based on the permanent magnet method, magnetic driving and fluid measurement systems for in-pipe capsule robots were established. Using computational fluid dynamics (CFD) and particle image velocimetry (PIV), the fluid velocity and vorticity in the pipe of the capsule robot were calculated and measured. The running characteristics of the capsule robot were numerically analyzed in the curved pipe and the peristaltic flow. Furthermore, the range and variance method of orthogonal design was used to analyze the influence of four typical parameters (namely, pipe diameter, robotic translational speed, robotic rotational speed, and fluid viscosity) on the three operating performance indicators of the capsule robot (namely, the forward resistance of the robot, fluid turbulent intensity near the robot, and maximum fluid pressure to the pipe wall). In this paper, the relative magnitude and significance of the influence of each typical parameter on different performance indicators of the robot are presented. According to the different performance requirements of the robot, the different four parameter combinations are optimized. It is hoped that this work provides a reference for the selection of the appropriate mucus, translational speed, and rotational speed of the robot when it is working in pipes with different diameters.

Performances comparison of axial-flux permanent-magnet generators for small-scale vertical-axis wind turbine

The use of wind energy as an alternative source of energy to generate the electricity is increasing worldwide. The application of an axial flux permanent magnet generator for small-scale wind turbine nowadays is increasing due to innovation, new material discoveries and completion in the manufacturing technology. The axial flux machines can be constructed with single-side, double-side and multi-stage topologies and can also be constructed with or without an iron core. Nine possible patterns between the single-side and double-side topologies with iron core and with surface-mounted permanent magnet method were designed in this study with the aid of the analytical method. To obtain the most qualified generator, there are six parameters used as constraints including flux density distribution, on-load terminal voltage, voltage regulation, total harmonic distortion, output power, and efficiency and analyzed with the finite element method from Maxwell-3D software. From the comparison, the generator type IX excited with rectangular poles is proven to be the most qualified generator among other generators in this case.

A STUDY OF FACTOR AFFECTING THE USE OF TEMPORARY AND PERMANENT METHODS OF CONTRACEPTION AMONG MARRIED WOMEN

Introduction: According to World Health Organization (WHO), 'Family planning allows individuals and couples to anticipate and attain their desired number of children and the spacing and timing of their births. It is achieved through use of contraceptive methods and the treatment of involuntary infertility'. This study provides the relationship between sociodemographic factors and use of temporary contraceptive methods and permanent contraceptive methods. 1.To de Objectives: termines the factor affecting utilization of temporary and permanent contraceptives among married women. 2. To determine the relationship between socio demographic factors and use of modern contraceptive method among married women.Material &amp; methods: This study was community based descriptive cross sectional study, conducted in urban area of Bilaspur (C.G.). Total 600 married women were interviewed by predesigned and pretested questionnaire. Data were analyzed using SPSS software. Chi-square test and logistic regression was applied to know the association among the various socioeconomic factors and contraceptive practices. In this study 600 married wome Result: n were studied. Out of all 600 respondent (172)28.7% were using sterilization and rest were using temporary method of contraception. Only 8.6% and 32.8% illiterate women were using temporary method and permanent method of contraception and only 42.9% and 21.4% women of lower socio economic class were using permanent method and spacing method of contraception respectively. Signicant association was found between various factors like age, education, parity, socio economic class, and number of living children. In this study choice of method of contrace Conclusion: ption (temporary and permanent methods) was associated with education, occupation, socioeconomic class, number of living children and parity. It was found that the female sterilization (permanent method) was more popular than temporary method. Education and mass media show signicant association in use of temporary methods.
