Evaluasi Permasalahan Kekuatan Splicing Benang pada Mesin Winding PT INS dengan Metode Seven Tools

Yarn manufacturing engineering stands as one of the initial phases in the textile industry and holds considerable significance in determining subsequent process qualities. PT INS specializes in producing ring spun yarn, wherein the final stage integrates an automatic yarn quality control mechanism within the winding machine. When the sensor identifies any yarn irregularity, an automatic cutting process initiates. Additionally, the winding machine incorporates a yarn splicing procedure to reconnect separated yarn ends or join yarn during cop changes. Any flaw in this splicing process can lead to a weak yarn splice, evident in the diminished Retained Spliced Strength (RSS), which in turn impacts subsequent weaving and knitting processes. PT INS encountered a yarn splicing issue, evidenced by consistently low RSS values from each spindle on its winding machines. An analysis was conducted employing various tools, including Control Charts, Fishbone Diagrams, Check Sheets, and Pareto Diagrams, to pinpoint the problematic spindle and identify the root cause of the splicing problem. Subsequently, improvement measures were proposed based on the analysis of each contributing factor. These steps aim not only to enhance the splicing process within the winding machine but also to elevate overall yarn quality. Through this approach, PT INS aims to rectify the splicing discrepancies, ultimately ensuring a more robust splicing process within the winding machine and elevating the overall yarn quality.

Speech and swallowing characteristics in patients with facioscapulohumeral muscular dystrophy.

Although facial muscle weakness is common in patients with Facioscapulohumeral Muscular Dystrophy (FSHD), the literature is scarce on the speech and swallowing aspects. To investigate speech and swallowing patterns in FSHD and assess the correlation with clinical data. A cross-sectional study was conducted. Patients with clinical confirmation of FSHD and aged above 18 years were included and paired with healthy control individuals by age and gender. Individuals who had neurological conditions that could interfere with test results were excluded. The following assessments were applied: speech tests (acoustic and auditory-perceptual analysis); swallowing tests with the Northwestern Dysphagia Patient Check Sheet (NDPCS), the Eat Assessment Tool (EAT-10), the Speech Therapy Protocol for Dysphagia Risk (PARD), and the Functional Oral Intake Scale (FOIS); disease staging using the modified Gardner-Medwin-Walton scale (GMWS); and quality of life with the Medical Outcomes Study 36-Item Short-Form Health Survey (SF-36). The correlation between test results and clinical data was verified by non-parametric statistics. Thirteen individuals with FSHD and 10 healthy controls were evaluated. The groups presented significant differences in the motor bases of phonation and breathing. Regarding swallowing, two (15%) individuals presented mild dysphagia and seven (53.8%) showed reduced facial muscles strength. These results were not correlated with duration of the disease, age at symptoms onset, and quality of life. Dysphagia was related to worsening disease severity. FSHD patients presented mild dysarthria and dysphagia. Frequent monitoring of these symptoms could be an important way to provide early rehabilitation and better quality of life.

Usefulness of Simple Dietary Check Sheet as Screening Tool to Assess the Risk of Muscle Mass Reduction in Community-Dwelling Middle-Aged and Older Adults

The aim of this study was to investigate the usefulness of a simple dietary check sheet to assess the risk of muscle mass reduction in middle-aged and older adults. The study participants comprised 1,272 community-dwelling individuals aged 50-89 years (mean age; 68.7 years). Bioelectrical impedance analysis was performed to estimate the appendicular skeletal muscle mass index (SMI, kg/m2). The SMIs were expressed as z-scores and adjusted for age and gender. A simple dietary check sheet was used to assess the daily intake of foods associated with maintaining muscle mass, such as meat, fish, eggs, milk, soybean products, and vegetables. Individuals with reduced muscle masses (SMI z-scores < -1.0) had significantly lower intakes of meat, fish, eggs, milk, and vegetables, and a lower overall dietary intake than individuals without reduced muscle masses (SMI z-scores ≥ -1.0). Food intake score was calculated to obtain quantitative estimates of the daily intake of these foods. The scores ranged from 0 to 14, with higher scores indicating higher intakes of foods that contribute to maintaining the muscle mass. Compared with the reference group with scores of ≥ 10, the groups with lower scores were at a higher risk of muscle mass reduction. The odds ratios (95% confidence interval) of the groups with scores of 9, 8, 7, 6, and ≤ 5 were 1.15 (0.42-3.13), 2.10 (0.89-4.95), 3.64 (1.61-8.23), 4.49 (1.90-10.58), and 7.53 (3.06-18.51), respectively, after adjusting for age, gender, obesity, alcohol intake, smoking, physical inactivity, hypertriglyceridemia, diabetes mellitus, and liver dysfunction. As the food intake scores were significantly associated with decreased muscle mass, the proposed simple dietary check sheet may help assess the risk of muscle mass reduction in middle-aged and older adults from a nutritional perspective.

The effects of the "Tabepo Check Sheet," which lists 10 food groups, on the dietary variety of older adults in a metropolitan area

Objectives This study examined the effects of checking the "Tabepo Check Sheet," which has 10 food groups, on changes in dietary variety among older adults living in Japanese metropolitan areas.Methods We used baseline and two-year follow-up data from a community-wide intervention to prevent frailty in Ota City, Tokyo. A total of 8,635 non-disabled residents (4,145 men and 4,490 women) aged 65-84 years who responded to the self-administered questionnaire surveys in 2016 and 2018, were included in the two analyses. In 2018, we asked about their experience with the "Tabepo Check Sheet," which had been distributed among participating communities from three districts in Ota City since July 2017. The "checked group" consists of those who answered "habitually check" or "have checked." Dietary variety was assessed using the Dietary Variety Score (DVS). We performed propensity score matching with a 1:1 ratio (checked group vs. non-checked group) for the following variables: demographic, socioeconomic, physical, medical, and lifestyle variables, and DVS. After propensity score matching, 876 participants from the checked and non-checked groups were selected. We used a two-way ANOVA to examine the changes in DVS over two years. We also compared the rates of DVS ≤3 and ≥7 points in 2018 using multivariate adjusted logistic regression analysis.Results In 2018, 11.9% of the respondents had checked the "Tabepo Check Sheet." The DVS mean±standard deviation in the checked and non-checked groups were 3.9±2.2 points and 3.9±2.3 points in 2016, respectively, and 4.5±2.4 points and 4.1±2.4 points in 2018, respectively. The DVS showed a significant interaction between checking experience and time (p<0.001). The rates of DVS ≤3 points in 2018 were 35.2% and 43.8% among the checked and non-checked groups, respectively. The multivariate adjusted odds ratio (OR) of DVS ≤3 points was 0.68 (95% confidence interval [95% CI] 0.56-0.83) in the checked group versus the non-checked group. The rates of DVS ≥7 points in 2018 were 21.7% and 16.8% among the checked and non-checked groups, respectively. The multivariate adjusted OR (95% CI) of DVS ≥7 points was 1.40 (1.10-1.78) in the checked versus the non-checked group.Conclusions These results suggest that checking the "Tabepo Check Sheet" may improve dietary variety. However, the effects of dietary variety improvement may be weakened by the incidence of skipped meals, social isolation, frailty, and lack of social participation.

Reliability and Validity of Facial Check Sheet (FCS): Checklist for Self-Satisfaction with Cosmetic Acupuncture.

Background: In recent years, cosmetic acupuncture has gained popularity among individuals interested in improving their facial appearance. We have created an original facial check sheet (FCS) to obtain cosmetic acupuncture patients’ perspectives on treatment outcomes. This study examined the reliability and validity of FCS. Methods: We conducted an Internet survey on the appearance of the facial region among Japanese women. A reliability analysis was performed between each item of FCS. A multiple comparison procedure was used to determine the relationship between the age group, the FCS score, and the number of terms used in the open-ended question. Results: The most frequently stated concern was blotchiness and hyperpigmented spots (47.2%, n = 67). The FCS items showed reliability (Cronbach α = 0.871). The number of extracted terms and the FCS score showed a moderate correlation (r = 0.407; p < 0.001). There was a significant relationship between age and FCS score (p = 0.005, r2 = 0.255), which indicated that the FCS score increases with aging. Conclusions: The FCS can be used as a practical tool to evaluate facial appearances and assess satisfaction levels of patients who underwent cosmetic acupuncture or other facial skin rejuvenation procedures.
