An Expert System for Bolt Selection

Expert systems are one of the widely used artificial intelligence techniques and their use is increasing day by day. Expert systems are a technique that can use the knowledge and experience of experts, evaluate them at the decision-making stage and make inferences. Bolts are fasteners used to connect various parts and are within the scope of standard machine elements. There are different types of bolts in the industry and choosing the right bolt requires expertise. In this study, an expert system called Exbolt System, which selects bolts according to head types, was developed. Commonly used standard bolt types were based on bolt head types. Relevant rules for bolt types were established by collecting and analysing information about each bolt. While the rules were written, it was aimed to choose the truest bolt type. Criteria such as the need for fine-tuning, use in rotating parts, centring in the hole, flat surface requirement, mounting accuracy, system weight status, high force-holding and use in dirty environments were considered in the creation of the rules. The programme makes the best choice and recommends the bolt that can be used according to the head type to the user. CLIPS expert system programming language was used in the development of the Exbolt System. With the answers to the questions asked to the user by the programme, it was ensured that the truest bolt selection was made. The most accurate result was achieved by making faster, easier and more comprehensive decisions in the bolt selection, which requires expertise, and a more effective and efficient selection process was realised by saving time and labour.

THE SOCIO ECOLOGICAL TRACTATE ON THE ENVIRONMENT

In the system of the international communication between countries in the world in use is the term “Dirty State”. The term is a whole composed of characteristics related to the quality of the elements and the geo-physical situations on the environment on some territories in the divided international community. According the negative picture and bad conditions of living in our social and nature ambience, with big amounts of garbage, dirty air and bad quality of the land and waters and the low living standards on its territory, the Republic of Northern Macedonia is classified as a problematic eco country. By the professionals in the fields and the tourist public, such a situation in the documents on this topic, in the critic world and in the sciences is unfortunately defined and marked as a “Dirty State”. Although this formulation causes uncomfortable feelings to the people in Macedonian society, but the facts are facts. However, the sciences and the knowledgeable in this issue (primary, the sociology and the ecology) confirms the nickname Dirty state as a real one. It is not only bad feelings or sort of theory of conspiracy, but it is obvious condition in the country. Unfortunately, the pollution of the Macedonian living space (especially the garbage and the dirty environment) among the citizens of RSM is still experienced more as a greed, carelessness, homelessness, as a waste and pollution. But, it must be overrun as an opinion, as a practice and as a theoretical approach. There must overcome a new contemporary approach that the waste is a great resource which could save the world of living and production of the unknowing uncertain and dangerous future for the mankind. The aim of this treatise is to contribute to further elucidation of the term, and to provoke further human efforts of the individuals and their communities and organizations in strengthening the quality of the environment, i.e. its further humanization.

Occupational hazards associated with frozen fish marketing in Abeokuta metropolis in Ogun State, Nigeria

This study assessed the occupational hazards and injuries associated with frozen fish marketers in Abeokuta metropolis, Ogun State of Nigeria. A two-stage sampling procedure was adopted in sampling 150 fish marketers from 10 popular markets within the study area. Data were elicited with the aid of an interview schedule and analyzed using descriptive statistics such as frequency distribution, percentage, mean, standard deviation, and Pearson’s Product Moment Correlation (PPMC) analytical tools. Results obtained showed that the mean age of the fish marketers was 37.96±11.04 years, the majority were females (87.9%), married (83.2%), and had a mean household size of 9.00±4.00 persons. Also, 54.4% and 42.3% of the fish marketers had secondary and tertiary education, respectively. In terms of safety measures adopted, all the fish marketers used pain relievers after work, while higher proportions usually use hand gloves (76.5%), wear nose masks (86.6%), wear an apron (80.5%), use plaster in cases of cuts (53.7%) and do regular medical check-up (49.7%). Most (60.4%) of the fish marketers were found to be in good/safe working conditions, while more than half (53.0%) of them were exposed to a high level of hazard. A significant negative relationship existed between working conditions and the level of hazard experienced by the fish marketers (r = –0.721, p ≤ 0.01). It was concluded that occupational hazards are associated with frozen fish marketing. The study recommended that fish marketers should operate from shops to avoid dirty, dusty, and noisy environments to improve their working conditions.

Factors That Interfere in the Action of Sanitizers against Ochratoxigenic Fungi Deteriorating Dry-Cured Meat Products

This study verified the factors affecting the antifungal efficacy of sanitizers against ochratoxin A-producing fungi. The fungi Penicillium nordicum, Penicillium verrucosum, and Aspergillus westerdijkiae were exposed to three sanitizers at three concentrations: peracetic acid (0.3, 0.6, 1%), benzalkonium chloride (0.3, 1.2, 2%), and sodium hypochlorite (0.5, 0.75, 1%) at three exposure times (10, 15, and 20 min), three temperatures (10, 25, and 40 °C), and with the presence of organic matter simulating clean (0.3%) and dirty (3%) environments. All the tested conditions influenced the antifungal action of the tested sanitizers. Peracetic acid and benzalkonium chloride were the most effective sanitizers, and sodium hypochlorite was ineffective according to the parameters evaluated. The amount of organic matter reduced the antifungal ability of all sanitizers. The longer exposure time was more effective for inactivating fungi. The temperature acted differently for benzalkonium chloride, which tended to be favored at low temperatures, than for sodium hypochlorite and peracetic acid, which were more effective at higher temperatures. The knowledge of the parameters that influence the action of sanitizers on spoilage fungi is vital in decision-making related to sanitizing processes in the food industry.

Tissue cysts and serological detection toxoplasmosis among wild rats from Surabaya, East Java, Indonesia.

The protozoan Toxoplasma gondii is the source of zoonosis toxoplasmosis and causes public health problems throughout the world. Environmental contamination by oocysts excreted by cats as definitive hosts affects the spread of this disease. Wild rats as rodents can be used as an indicator of environmental contamination by oocysts, considering that rats have a habit of living in dirty environments and can be infected by oocysts from the environment. This study aims to detect toxoplasmosis from tissue cysts and serological tests in wild rats as an indicator of environmental contamination in Surabaya. A total of 100 wild rats collected from Surabaya were collected in five areas (West, East, Central, North, and South of Surabaya) obtained from three trapping locations: housing, dense settlements, and markets. All samples were examined microscopically for parasitological tests through the brain tissue samples, and the serum was examined using the toxoplasma modified agglutination test to detect the presence of IgG and Immunoglobulin M (IgM). This research used 100 wild rat samples, 77 Rattus tanezumi and 33 Rattus norvegicus, with evidence of 31% in serology and active infection with 19% tissue cyst. The results showed that the seroprevalence of T. gondii in wild rats was 31% (30% for IgG and 1% for IgM). Tissue cysts in the rat brain samples tested were 19% (19/100). The IgG prevalence rate in female rats was 25% (8/32), while for males, it was 32.3% (22/68). The highest seropositive IgG from densely populated settlements was 50%, markets were 25.8%, and housing was 12.1%. The highest seropositive IgM from densely populated settlements was 2.8%. Population density and the presence of cats are factors supporting the high seropositive rate at the trapping location. This study revealed that there has been toxoplasmosis contamination in Surabaya with evidence of 31% in serology and active infection with 19% tissue cyst. It is necessary for controlling with surveillance in cats to prevent transmission in humans.

PERKEMBANGAN KANAL OUD BATAVIA ABAD XVII–XX: TINJAUAN SEJARAH PERKOTAAN

Urban environmental problems such as flooding and water pollution have actually occurred in Jakarta (formerly Batavia) since the Dutch colonial era. Batavia was one of the cities with a myriad of urban planning problems, such as canal flooding which continues to this day. This article was written to find the root of the water problem in Jakarta by reviewing the development of canal construction from the Oud Batavia to the Nieuwe Batavia era. This study was conducted to identify the colonial government’s methods for dealing with flooding and repairing problematic canals. Thus, this research is expected to provide an insight for the current government on ways to deal with flood problems in Jakarta in the contemporary era. Results show that the expansion of settlements from Kota Tua to Weltevreden was also influenced by the dirty canal environment in Oud Batavia. Dirty, sedimentary, and problematic canals were restored, but the old problems persist. Then, Weltevreden was chosen as Ommelanden (expansion area) of Oud Batavia.

Helminthiasis Identification on Bengal Tiger (Panthera tigris tigris)

Bengal tiger (Panthera Tigris) is a mammal in the big cat family. The decrease in the Bengal tiger population can be caused by helminth infections. The impact of helminth infection on Bengal tiger in short term does not show any clinical symptoms. The examination was carried out to identify gastrointestinal infections in Bengal tiger (Panthera Tigris) conducted at Maharani Zoo Lamongan, East Java. 5 samples of Bengal tiger feces were used for examination purpose. The examination of fecal samples on Bengal tigers was carried out qualitatively using the native method and the floating method. The results of the examination of 5 Bengal tigers at Maharani Zoo showed 1 positive for Ascarid eggs on native examination and on floating examination showed 2 positive samples for Strongylid eggs and 5 positive samples for Ascarid eggs. The percentage of helminthiasis in the Bengal tigers was 100% positive for helminth infection. The helminth infections at Maharani Zoo could be caused by damp cage, humid and dirty environment, food and water that were contaminated with helminth eggs. The treatment given for the Bengal tigers at Maharani Zoo used  Kalbazen® that contains 1000mg albendazole.

Coolant circulation improvement on the chip tub of the machine lnc okuma 0002 pt. komatsu undercarriage indonesia

In general, coolant is a cooling medium used to cool workpieces and cutting tools during the machining process. In PT Komatsu Undercariage Indonesia, the LNC OKUMA 0002 chip crankcase contained a lot of stagnant coolants. The factor that causes the coolant to stagnate is that the growl is wasted through the chip conveyor and the coolant is carried along with the growl to the chip. Changing the coolant fluid needs to be done in a certain phase because the use of the coolant for too long causes sand to accumulate. Excessive sand can close the cooling duct system. The quality of the coolant can deteriorate due to heat and a dirty environment. In addition, corrosion on the radiator can also result in the deposition of dirt on the coolant. When this happens, the engine overheats easily and triggers a stall. The repairs that have been carried out are examining and repairing the components of the coolant system by adding a coolant channel and a pump that functions to suck the coolant so that the coolant returns to the LNC OKUMA 0002 engine.

Control of Arm Robot Based on Finger Motion

Robotics is a constantly evolving field nowadays. A robot is a mechanical device that can perform physical tasks while being controlled and supervised by humans. Several robots have been created to perform risky tasks impossible for humans to act directly. The robot arm is one of the most popular types. In this project, it is proposed to control a robot arm using finger and hand movements. However, the traditional way of gesture control employs sensor-based gloves to track motion, which is time and energy-intensive due to its weight. To overcome this problem, using vision for motion tracking can be the most suited method at hand currently. The ML-based computer vision method provides real-time landmarks on different hand points. With these landmarks, we can calculate various mathematical parameters that can be used to control the robot arm. Movements that are landmarked are processed and formulated using mathematical parameters. The final output of mathematical parameters is fed to the microcontroller. Signals from the microcontroller will be the desired input signal to the motors. The rotation of the robot arm is controlled using the movement of the human arm. This project’s end application is like human operation in dull, dirty, and dangerous environments. The project’s primary goal is to protect those who come into direct contact with these environments. Bomb defusing, painting, welding, and other applications are a few examples of where this project is helpful.

Assessment of the Social and Physical Characteristics of Obiagu Shanty Area in Enugu Metropolitan City, Nigeria

The persistent rise of the urban population and high housing rent has driven many to shanty towns. However, due to the increased population of the shanty towns, the social and physical characteristics of the towns have deteriorated. The study assessed the social and physical characteristics of Obiagu Shanty Area in Enugu Metropolitan City, Nigeria, with the purpose of establishing the extent of the rehabilitation and its impacts in the lives of the residents, as well as provides a better alternative. The data was obtained using a questionnaire survey. The statistical techniques employed to analyse the data are descriptive statistics (such as simple percentages, standard deviation and mean). The study, in general terms identified that the level of physical and social characteristics of Obiagu Shanty Area is highly negative. The study also reveals poor infrastructural amenities in the area. It demonstrates that the government is failing to fulfill its responsibilities in terms of urban development and infrastructure renewal. Furthermore, the study shows that private individuals and communities do not actively participate in urban regeneration and infrastructural renewal efforts in Obiagu Shanty Area. Therefore, the study recommends some retrofitting measures, such as the construction of modern houses with modern facilities and good sewage systems, the government partnering with private organisations/individuals or the community to assist in the remodeling of structures in the area, and constant sensitisation of residents by the government and NGOs on the negative health consequences of living in a dirty environment, among other things.

DEVELOPING PREDICTIVE MODEL FOR POVERTY AND COVID-19 INCIDENCES IN NIGERIA

Poverty is one of the greatest challenges facing the world today. This is because it is a major cause of ill-health by forcing people to live in dirty environments and a barrier to accessing health care, especially in the developing world. As a result of these, it was predicted that the outbreak of the COVID-19 pandemic will pose a devastating impact on households living beneath the economic, social, health and educational services thresholds. This impact will stem from the direct and indirect effects of the illness and the transmission control policies of governments. Consequently, this study assessed the COVID-19 preventive strategies adopted as well as the statistical relationship between the pre and post-lockdown household income poverty in Minna, Nigeria. The study similarly developed a predictive model for the nexus between poverty headcount ratio and the incidence of COVID-19 in Nigeria. Both the primary and secondary sources of data were employed for this study and the data were analysed using descriptive and inferential statistics (t-Test and regression techniques). The outcome showed that there exists a statistically significant difference between the pre-lockdown poverty rate and the post-lockdown poverty rate in Minna. The study also revealed that for each unit increase in poverty headcount ratio, the incidences of COVID-19 cases and its fatalities decreases by -42.5625 and -0.56077 units respectively. The study, therefore, recommended the domestication of the existing social intervention programmes of the Federal Government, by States Governments in order to enhance the standard of living of more households. It was also recommended that all stakeholders most partake in enlightenment and sensitization programmes on the need to adopt preventive measures to guard against the transmission of the virus.

EDUCATION GUIDELINES FOR BALANCED NUTRITION FOR PRE-SCHOOL CHILDREN IN METHODIST-6 KINDERGARTEN MEDAN

Preschool is the time when children are between the ages of 3 to 6 years, where in this phase, they experience a periode of increasing various competencies in themselves in order to prepare them for school. At this time, the child will display optimal development which is shown in his daily life the child receive adequate nutrition, appropriate stimulation for development and proper education. Preschool children had the characteristics of active self-consumption, where children tend to choose foods what they like. This condition allowed a larger number of children in this group to be exposed to a dirty environment, where this situation provides a greater opportunity for infection from various kinds of diseases to children as well as non-optimal nutrition from inadequate food consumption will be associated with worsening health. Kindergarten Methodist-6 was located near the main road where around the school location there were snack for school children.

Educational measurement through pictorial quiz consists of 7 questions. Health education regarding balanced nutrition guidelines increased children’s knowledge by 38%. Health education regarding balanced nutrition guidelines can increase knowledge of kindergarten children.

Association of Soil-Transmitted Helminths Infection with Total Serum Immunoglobulin E Levels and Total Eosinophils in Elementary School Students in Medan

BACKGROUND: Soil-transmitted helminths infection is widespread in tropical and subtropical areas. More than 267 million preschool-aged children and more than 568 million school-age children live in areas where this parasite is transmitted intensively and requires treatment and prevention. People at risk are preschool children, school-aged children, reproductive age women, and adults in certain high-risk occupations, such as tea pickers or miners. Worm infections often infect elementary schoolchildren because at this time, children have many activities and are often in direct contact with a dirty environment so that it can cause children not to pay attention to personal hygiene. AIM: This study aimed to determine the association of STH infection with total serum IgE levels and eosinophil counts in elementary school students in Medan. METHODS: This cross-sectional study was conducted on 65 elementary school students at Medan orphanage who met inclusion and exclusion criteria. Examination of STH infection was carried out using Kato-Katz method, and blood tests were performed to assess total serum IgE and blood eosinophils counts. Univariate and bivariate analysis was performed to determine the association of STH infection with total serum IgE levels and eosinophil counts in these students using Pearson correlation test and Chi-square. RESULTS: Of the 65 elementary school students in the orphanage who were willing to have their routine blood and feces checked, 36 boys (55.3%) and 29 girls (44.6%), 39 children were infected with STH (60%). The most common infections were Ascaris lumbricoides (26.1%), Trichuris trichiura (18.4%), and mixed infections (15.3%) with an average of mild infection intensity. The results of the analysis showed that there was no significant association between STH infection and eosinophils counts (p = 0.582, 95% confidence interval, OR 1.3). In addition, there was also no significant association of STH infection with total serum IgE levels (p = 0.883, 95% confidence interval, OR 63.6). CONCLUSION: In this study, there was no association between STH infection with eosinophils counts and total serum immunoglobulin E levels in elementary school students in Medan.

Application of 5S Management in Improving the Quality of Furniture Production in Meubel Karya Agung of Ponorogo Regency

5S (Sort, Set in order, Shine, Standardize, dan Self Discipline) is a work culture that must be applied in all workplaces both in the formal and informal sectors. The implementation of 5S aims to make workers feel comfortable and safe while working. In addition, the application of 5S can make work more effective and efficient because it can eliminate wasted time due to more time to search for goods, work areas that look full due to excess equipment and un needed goods or dirty environments. Furniture Works In Semanding District, Kauman, Ponorogo is one of the informal sectors that have not implemented 5R. This is seen from the condition of the work area full of unnecessary equipment and goods, messy, and dirty. Therefore, researchers conducted research analysis of the application of 5S in Furniture Works. Purpose: The purpose of the research to know the application of the principle of 5S in Furniture Works. Method: This research uses qualitative design. The research was conducted with direct observation and using the 5S checklist. Research Results: The results showed that the application of 5S in Furniture Works is still not good. This is evident from the achievement of the 5S as a whole which is below 50%. Conclusion: The results of the study concluded that the implementation of 5S in Furniture Works is still lacking so it is necessary to conduct training on 5S and internal audits periodically.

Covid-19 Related Factors Associated with Antenatal Care in Rural Bangladesh: A qualitative study

Objective: Available literature reveals that usage of Maternal Health Care Services (MHCSs), including antenatal care (ANC), has been decreased significantly in the developing countries due to Corona Virus Disease (COVID-19) pandemic. However, the COVID-19 related factors on the MHCSs utilization in Bangladeshi women are yet to be examined. Therefore, this study examines the effect of COVID-19 on the use of ANC services among rural communities in Bangladesh.Method: A community-based qualitative study was conducted from May 01, 2021, to July 20, 2021, among selected pregnant women residing in eight villages of the Kushtia District, Bangladesh. A total of ten focus group discussions (FGDs) was conducted. Open Code 4.0 software was used to transcribe, translate, and analyze the data thematically. Results: Findings suggest that the measures taken by the government against the COVID-19 pandemic have significantly decreased the optimum usage of ANC services. The need to shift the role of the health workforces a vital factor that has a negative effect on women's attitude towards seeking MHCSs. Anxiety, dirty and poor environment of the health facilities, low quality of care, stigma, and risk minimization strategy are among other factors that refrained the pregnant women from seeking ANC services. Conclusion: Undoubtedly, the COVID-19 related factors have decreased the possible usage of ANC services among rural communities in Bangladesh. Additional necessary health workforces are needed to recruit urgently. A special wing for pregnant women in each health facility may be opened as a one-stop service center for the COVID-19 period. The policymakers should take necessary actions to reduce anxiety among pregnant women and motivate them to use MHCSs for safe motherhood.

Functional and expression characteristics identification of Phormicins, novel AMPs from Musca domestica with anti-MRSA biofilm activity, in response to different stimuli

Antibiotic-resistant bacteria (including MRSA) in the clinic pose a growing threat to public health, and antimicrobial peptides (AMPs) have great potential as efficient treatment alternatives. Houseflies have evolved over long periods in complex, dirty environments, developing a special immune system to overcome challenges in harmful environments. AMPs are key innate immune molecules. Herein, two differentially expressed AMPs, Phormicins A and B, were identified by screening transcriptomic changes in response to microbial stimulation. Structural mimic assays indicated that these AMPs exhibited functional divergence due to their C-terminal features. Expression analysis showed that they had different expression patterns. Phormicin B had higher constitutive expression than Phormicin A. However, Phormicin B was sharply downregulated, whereas Phormicin A was highly upregulated, after microbial stimulation. The MIC, MBC and time-growth curves showed the antibacterial spectrum of these peptides. Crystal violet staining and SEM showed that Phormicin D inhibited MRSA biofilm formation. TEM suggested that Phormicin D disrupted the MRSA cell membrane. Furthermore, Phormicin D inhibited biofilm formation by downregulating the expression of biofilm-related genes, including altE and embp. Therefore, housefly Phormicins were functionally characterized as having differential expression patterns and antibacterial & antibiofilm activities. This study provides a new potential peptide for clinical MRSA therapy.
