  • Objective: This paper presents the factors influencing the effectiveness of materials handling equipments in agriculture. Background: Agriculture is one of the job categories where work-related musculoskeletal disorders(MSDs) are the most common. Statistics shows that majority of farm workers is exposed to repetitive and forceful body movements, lifting, lowering, pushing, pulling, or carrying heavy materials. In such a working environment, materials handling equipments are required and introduced to assist in the prevention of MSDs and other farm injuries. Method: Examples of materials handling equipments are rail carts, portable lifts, and bale handlers. Contributing factors influencing the effectiveness of materials handling equipments supplied in agriculture were identified based on the lessons learned from previous government-funded ergonomic projects. Results: Contributing factors identified include: (1) forward-looking attitude for the standardization of farming, its environments, and handling equipments, (2) participation of farm members in the process and evaluation of project, (3) leadership of project manager, (4) reinforcement of safety education and training, and (5) project selection and priority of handling equipment. Conclusion: Government-funded research planners, farmers, ergonomists, and farm machine experts are recommended to consider the factors identified when implementing materials handling equipments in agriculture. Application: Actual or potential application of this research includes recommendation for the effective implementation of material materials handling equipments in agricultural sectors.

  • Objective : In Modern society, patients with facial nerve paralysis are increasing because of many factors - irregular life, cold, overwork and stress etc. We have troubles in presuming the prognosis, though how to diagnosis and examine facial nerve paralysis are many. Methods : A clinical study was done on 89 patients who were diagnosed and treated as facial nerve paralysis(Bell's palsy) from January 2001 to May 2003 at the Dep. of Acupuncture and Moxibustion, college of Oriental Medicine, Woo-suk University. We classified 89 patients as the Sasang(四象) constitution, contributing factor, season, age and existence of diabetes items and analyzed, as we would research differences of changing point-Period from on set of Bell's palsy to the day which the change begins to be seen at the face- and improvement -Period which Bell's palsy is improved from on set to H-B grade II. Results : 1. Among the Sasang constitution, Soeumin($10.67{\pm}3.77days$) were faster than other constitutions, but Soyangin($16.25{\pm}6.75days$) were slower than other constitutions in changing point. Taeumin($4.12{\pm}1.49weeks$) were shorter than other constitutions, but Soyangin($4.88{\pm}2.11weeks$) were longer than other constitutions in improvement. 2. Among contributing factors, overwork and stress group were slower than other contributing factors in changing point($13.95{\pm}6.52days$), and longer than others in improvement($4.67{\pm}1.87weeks$). 3. Changing point and improvement of season, age, and existence of diabetes had the difference of the average according to an each item, but they were not statistically significant. 4. In 89 patients with Bell's palsy, average changing-point was $13.11{\pm}5.99$(days) and average improvement was $4.47{\pm}1.82$(weeks). Their correlation was 0.687 and statistically significance(P<0.01), therefore we could decide that their relation is highly correlation.

  • Objectives: There is an increasing number of North Korean adolescents in South Korea. These adolescents need clinical attention as they experience a high risk of suicidal behavior because of the childhood adversity and acculturative challenges that they face before and after arriving in South Korea. This study assessed the risk of suicide attempts among North Korean adolescents compared to South Korean adolescents, and investigated the contributing factors for each group. Methods: We used data from the Korean Youth Risk Behavior Web-Based Survey (KYRBS) spanning 2011 to 2018, in which 404 adolescents had a father and/or mother who was a North Korean native. Data on 1,212 propensity-matched South Korean adolescents were extracted from the 2011 to 2018 KYRBS. Prevalence was calculated and compared by group. Separate odds ratios were calculated by group. Results: The North Korean group had a significantly higher suicide attempt rate [unadjusted odds ratio (OR)=8.27; adjusted OR=8.45]. Multivariate analysis indicated that having a low or high socioeconomic status and depressive symptoms were significantly associated with suicide attempts in North Korean adolescents, while being female, having a high socioeconomic status, alcohol use, and depressive symptoms were significantly related to suicide attempts in South Korean adolescents. Conclusion: The results found similarities and differences in the factors associated with the likelihood of suicide attempts in the two groups. From these results, different approaches are needed when planning interventions for each group.

  • Using Spradley's ethnographic method, the study was designed to describe and understand the factors contributing to the occupational socialization of librarians. Three in-depth interviews and one observation were conducted with each of the sixteen participants who have practiced for longer than 5 years in libraries and were selected by theoretical sampling. Eight factors emerged from the data: education in universities, social changes, work, human relationships, users, the library organizational climate, social perception, and striving to enhance the professional. 'Overcoming a lack of understanding about the profession' was the cultural theme for describing and integrating the factors contributing to the occupational socialization of librarians.

  • The purposes of this study were to compare financial status of home-based family business with that of ensile family business, and to analyze the factors effected on financial status of both business groups. The sample consisted of 295 home-based family business and 418 ensile family business among self-employed household of 1998 Korea Household Panel Data, and analyzed into Frequencies, Percentile, t-test, $\chi$$^2$-test and Regression. The findings were as follows: First, in case of financial status of household, there was no significant difference between home-based family business and ensile family business. Second, in case of financial status of business, total sales amount and net profit of home-based family business were lower than those of onsite family business, however net profit to total sales ratio of home-based family business was higher than those of onsite family business. Third, the factors contributing to total expenditure to total income ratio of home-based family business were business owner's present economic perception, future economic expectancy and residence, while business owner's age, the number of children and of tamer, and residence were significant variables contributing to same ratio of onsite family business. The factors contributing to total asset to total debt ratio of home-based family business was only business owner's future economic expectancy, however factors affected on the counterpart were business owler's future economic expectancy and job type of family business. Fourth, the variables of sex, age, educational level of family business owner, job type and family type of family business were associated with net profit to total sales ratio of home-based family business, and sex, educational level of family business owner, job type of family business, and the number of employees were related to same ratio of the counterpart. In addition, educational level of family business owner, job type and residence were related with total sales to the number of employees ratio of home-based family business, and educational level of family business owner and job tape of family business were related to same ratio of ensile family business.

  • Purpose: The aim of this retrospective study was to determine the prevalence of early implant failure using a single implant system and to identify the factors contributing to early implant failure. Methods: Patients who received implant treatment with a single implant system ($Luna^{(R)}$, Shinhung, Seoul, Korea) at Dankook University Dental Hospital from 2015 to 2017 were enrolled. The following data were collected for analysis: sex and age of the patient, seniority of the surgeon, diameter and length of the implant, position in the dental arch, access approach for sinus-floor elevation, and type of guided bone regeneration (GBR) procedure. The effect of each predictor was evaluated using the crude hazard ratio and the adjusted hazard ratio (aHR) in univariate and multivariate Cox regression analyses, respectively. Results: This study analyzed 1,031 implants in 409 patients, who comprised 169 females and 240 males with a median age of 54 years (interquartile range [IQR], 47-61 years) and were followed up for a median of 7.2 months (IQR, 5.6-9.9 months) after implant placement. Thirty-five implants were removed prior to final prosthesis delivery, and the cumulative survival rate in the early phase at the implant level was 95.6%. Multivariate regression analysis revealed that seniority of the surgeon (residents: aHR=2.86; 95% confidence interval [CI], 1.37-5.94) and the jaw in which the implant was placed (mandible: aHR=2.31; 95% CI, 1.12-4.76) exerted statistically significant effects on early implant failure after adjusting for sex, age, dimensions of the implant, and type of GBR procedure (preoperative and/or simultaneous) (P<0.05). Conclusions: Prospective studies are warranted to further elucidate the factors contributing to early implant failure. In the meantime, surgeons should receive appropriate training and carefully select the bone bed in order to minimize the risk of early implant failure.

  • BACKGROUND/OBJECTIVES: Malnutrition during hospitalization is linked to increased morbidity and mortality, but there are insufficient studies observing clinical factors contributing to weight loss during hospitalization in Indonesia. This study was therefore undertaken to determine the rate of weight loss during hospitalization and the contributing factors. SUBJECTS/METHODS: This was a prospective study involving hospitalized adult patients aged 18-59 yrs, conducted between July and September 2019. Body weight measurement was taken at the time of admission and on the last day of hospitalization. The factors studied were malnutrition at admission (body mass index < 18.5 kg/m2), immobilization, depression (Beck Depression Inventory-II Indonesia), polypharmacy, inflammatory status (neutrophil-lymphocytes ratio; NLR), comorbidity status (Charlson Comorbidity Index; CCI), and length of stay. RESULTS: Totally, 55 patients were included in the final analysis, with a median age of 39 (18-59 yrs) yrs. Of these, 27% had malnutrition at admission, 31% had a CCI score > 2, and 26% had an NLR value of ≥ 9. In all, 62% presented with gastrointestinal symptoms, and depression was documented in one-third of the subjects at admission. Overall, we recorded a mean weight loss of 0.41 kg (P = 0.038) during hospitalization, with significant weight loss observed among patients hospitalized for 7 days or more (P = 0.009). The bivariate analysis revealed that inflammatory status (P = 0.016) was associated with in-hospital weight loss, while the multivariate analysis determined that the contributing factors were length of stay (P < 0.001) and depression (P = 0.019). CONCLUSIONS: We found that inflammatory status of the patient might influence the incidence of weight loss during hospitalization, while depression and length of stay were independent predictors of weight loss during hospitalization.
