Objective : The purpose of this study was to establish the concurrent validity of the Korean Occupational Balance Assessment(OBA) tool. Methods : This study was conducted on 1016 people from October 1 to October 25, 2019. Data collection was performed using OBA and Occupational Balance Questionnaire11(OBQ11). The data were analyzed by descriptive statistics, Pearson correlation. Results : There was a significant correlation between the scores of the three areas of OBA and the total score of OBQ11(p<.01). All three areas were analyzed with positive correlations. The time use area (r = .554) and occupation frequency area (r = .574) were found to be correlated. Most of the sub-factors in the occupation characteristics area (importance r = .582, goal achievement r = .633, enjoyment r = .649, health r = .650) were analyzed with high correlation. Conclusion : OBA has proven to be a valid and reliable assessment tool for measuring occupational balance. Further research needs to provide guideline on occupational balance for usefulness in clinical area.

Background: The objective was to assess the knowledge level, attitude, and practice of health care workers towards standard precautions, and to identify the related factors. Furthermore, it was attempted to identify the proportion of having the experience of needle stick injuries (NSIs) and associated factors among participants. Methods: A cross-sectional study was conducted in a teaching hospital among 233 health workers using a self-administrated questionnaire. The questionnaire included eight knowledge items, seven practice items, and five attitude items. Based on the mean score of each category, responses were grouped into "satisfactory" and "unsatisfactory". Univariate, bivariate, and multivariable logistic regression analyses were done. Results: The mean age of the participants 32.95 (SD ± 9.70) and 62.2% of them were women. 57.5% of the staff had a satisfactory level of correct knowledge (>5 correct answers), 37.3% had a satisfactory positive attitude (>3 correct answers), and 30.9% had a satisfactory practice (>3 correct answers) towards standard precautions. The occupation was one of the predictors as doctors were less likely to have satisfactory knowledge and practice compared to nurses (OR = 0.269, 95% CI: 0.10-0.70 and OR = 0.248, 95% CI: 0.08-0.77, respectively). Out of 174 participants, 31.6% of them reported experiencing NSIs and support staff were 71% less likely to experience NSIs compared to nurses & paramedics. Conclusion: The findings revealed a substandard adherence of standard precautions among participants, which highlighted the necessity of the provision of a periodic, tailored training program based on the occupation and risk exposure.

Objectives: The purpose of this study was to suggest the clinical characteristics and risk factors of facial palsy from the perspective of Korean Medicine. Methods: Medical records of 856 patients, who visited the Korean Medicine hospital with facial palsy from 2004 to 2019, were retrospectively analyzed. The clinical characteristics of facial palsy were suggested by figuring out the distribution of age, sex, occupation, onset season, obesity, modes, signs, symptoms, past and family history. Results: By gender, there were more males (54.6%), and the most common age groups were in their 50s (27.4%) and 40s (23.6%). As for the occupation, unemployed (27.7%) and service and sales workers (14.6%) were the most common, and the onset season was the most common in winter (28.9%). The most common clinical characteristics were overwork (33.0%), mental stress (24.8%), and exposure to cold (19.3%) in modes, 'none' (64.3%), postauricular pain (33.2%) in signs, postauricular pain (26.9%), parageusia (14.8%) in symptoms. Hypertension and diabetes were the most common in both past and family history. In particular, the obesity rate of the subjects (59.8%) was much higher than that of Koreans (32.8%). Conclusions: Based on the historical Korean Medicine literature and the results of this study, it is suggested that overwork, stress, exposure to cold, and obesity are identified as risk factors for facial palsy. Furthermore, dysfunction of the stomach meridian is thought to contribute to the cause of facial palsy.

The purpose of this study was to examine the relationship between consumer spatial behavior and consumer characteristics based on trade area selection criteria 469 female consumers who lived in the two new towns near Seoul, Bundang and Ilsan, participated in the study by completing questionnaires. Data were analyzed by using cluster analysis, ANOVA, Duncan's multiple range test, chi-square analysis, etc. The findings of the empirical research were as follows: 1. Five groups were identified by cluster analysis based on trade area selection criteria of clothing price-oriented group, time convenience-oriented group, shopping convenience-oriented group, variety/entertainment-oriented group, and passive shopping group. 2. Each group differed in spatial behavior such as clothing shopping area, the visiting frequency, and spatial movement type. 3. Each group showed differences in fashion involvement and demographic characteristics(age, marital status, education, occupation and social status).

This paper proposes an effective fingerprint identification system with hardware block for thinning stage processing of a verification algorithm based on minutiae with 39% occupation of 32-bit RISC microprocessor cycle. Each step of a fingerprint algorithm is analyzed based on FPGA and ARMulator. This paper designs an effective hardware scheme for thinning stage processing using the Verilog-HDL in $160{\times}192$ pixel array. The ZS algorithm is applied for a thinning stage. The logic is also synthesized in $0.35{\mu}m$ 4-metal CMOS process. The layout is performed based on an auto placement-routing and post-simulation is performed in logic level. The result is compared with a conventional one.

Current seismic design codes do not contemplate explicitly some variables that are relevant for the design of structures subjected to ground motions exhibiting large energy content. Particularly, the lack of explicit consideration of the cumulative plastic demands and of the degradation of the hysteretic cycle may result in a significant underestimation of the lateral strength of reinforced concrete structures built on soft soils. This paper introduces and illustrates the use of a numerical performance-based methodology for the predesign of standard-occupation reinforced concrete ductile structures. The methodology takes into account two limit states, the performance of the non-structural system, and in the case of the life safety limit state, the effect of cumulative plastic demands and of the degradation of the hysteretic cycle on the assessment of structural performance.

This paper is concerned with the problem of recognizing definition sentences. Given a definition question like "Who is the person X?", we are to retrieve the definition sentences which capture descriptive information correspond variously to a person's age, occupation, of some role a person played in an event from the collection of news articles. In order to retrieve as many relevant sentences for the definition question as possible, we adopt a centroid based statistical approach which has been applied in summarization of multiple documents. To improve the precision and recall performance, the weight measure of centroid words is supplemented by using external knowledge resource such as Wikipedia and redundant candidate sentences are removed from candidate definitions. We see some improvements obtained by our approach over the baseline for 20 IT persons who have high document frequency.

The purpose of this study is to investigate some related factors which influence the well-being of the family life among the rural housewives, based on the satisfaction of the leisure. Questionnaires were distributed to the 200 housewives residing in Anseong. The 187 data obtained were analyzed by frequency, percentage, mean, F-test, Duncan’s multiple range test and correlation. The major findings of this study were summarized as follows. (1) There were significant differences on the satisfaction of sports leisure, culture center leisure and music and play leisure among the rural housewives according to the social demographic variables. (2) There were significant differences on the family life well-being among the rural housewives according to the satisfaction of sports leisure, the satisfaction of music and play leisure, the satisfaction of culture center leisure, the occupation of premarriage and the number of family members. Based on the above findings, it has been found that the satisfaction of leisure remains important factors to guide according to the radical changes. If greater attentions should be directed to the satisfaction of leisure activities, the quality of family life could be improved and stabilized.
