This study aimed to examine the development and characteristics of the workers with upper limb musculoskeletal symptoms and disorders and to analyze the upper limb musculoskeletal symptoms and disorders for its relationship with the individual socio-demographic characteristics. This study investigated the effect on the limitations of physical activities using standardized surveillance tool and clinical diagnosis. Musculoskeletal symptoms and the limitations of physical activities were examined. The clinical diagnosis of musculoskeletal disorders were carried out by physical examination, radiological examination and electromyography-electroneuronography for 22 workers in kitchen hood assembly process and 50 workers in toggle process of leather product manufacturing. The proportion of workers with musculoskeletal disorders was higher and the DASH score was also statistically higher in female and aged workers with longer working hours, longer household working hours, less leisure/hobby activity and higher physical load. Physical activities component score increased in the following order: workers in normal health, workers with musculoskeletal symptoms, and workers with musculoskeletal disorders as clinically diagnosed. Score for each DASH component increased in the following order: sports/performing arts ability, social activities, specific physical functional activities, work or other regular daily activities, work ability, psychological activities, insomnia and upper limb symptoms. The overall and each component DASH scores were higher in workers with symptoms of status praesens and of more severity, and receiving medical intervention. Musculoskeletal symptoms and disorders are associated with individual socio-demographic characteristics, and DASH score for physical activities of upper limb was higher in workers with musculoskeletal disorders. Musculoskeletal symptoms and disorders have a remarkable epidemiological significance for physical activities, social activities, work or other regular daily activities, upper limb symptoms and insomnia, where work ability, sports/performing arts ability and preventive measure is needed.

This study is to understand subculture as a selective amity or an emotional tribe that includes a life style, hobby and leisure of people and seeing it as the tribal solidarity or emotional alliance. Hence, based on the neo-tribalism by Michel Maffesoli who explains a tribe not composing a social vertical structure represented by class, but is composed a horizontal structure of individuals as a member of a society, this study conducted an empirical analysis on domestic minor fashion communities. Research findings show that they have a unique structure unexplained by Maffesoli. Fashion styles, values shared by domestic minor fashion communities are almost entirely based on individual likes and dislikes, escaping from a symbol of resistance to subordination explained by the existing subculture, play a role in enhancing the solidarity inside the community and confirming its identity outside. However, as for shared values within a community, it reveals a new invisible type of subculture intra-inter domestic minor fashion communities. A community showed a closed mind rather than open mind, disregarding or comparing with other communities and preventing their members from participation. A community had strict fashion rules and obvious classes, leading to participatory restriction. In conclusion, domestic minor fashion communities showed the most significant characteristic of a selective vertical structure by individual and community rather than a vertical structure by a society.

This study aimed to examine the general characteristics of individual workers, psychosocial working environment, and ergonomic risk factors which affect the status of musculoskeletal disorders. Self-report was carried out for musculoskeletal symptoms and ergonomic risks in working environment in 856 production workers in 16 small to medium sized manufacturing companies. Musculoskeletal symptoms were examined with a standardized questionnaire, and ergonomic risks were evaluated with a qualitative self-administered instrument for the tasks related to musculoskeletal disorders. Major findings were as follows: 1) Complaint rate for musculoskeletal symptoms was higher in female, aged, married workers with longer working hours, less leisure/hobby activity, longer household working hours and history of disease or accident. 2) Complaint rate for musculoskeletal symptoms was significantly higher in workers with dissatisfaction, difficult tasks, and no self-control at work. 3) Complaint rate for musculoskeletal symptoms was significantly higher in workers involved in tasks with major ergonomic risk factors, and handling heavy equipment. 4) Explanatory power increased the model with the musculoskeletal symptoms as dependent variable and demographic variables, psychosocial working environment and ergonomic risk factors included, and total explanatory power of 18.6% revealed the significant effect. Based on the results, we can conclude that musculoskeletal symptoms in manufacturing workers are associated with individual demographic characteristics, psychosocial working environment and ergonomic risk factors.

Social readjustment is very important in rehabilitation of stroke survivors. The purpose of this study was to examine the level of social readjustment and related factors in stroke survivors. Especially, to find the most useful predictor for social readjustment is a major point of this research. The study included 254 outpatients who were given follow-up care after discharge from. Occupational rehabilitation and resumption of the perceived meaningful social activity prios to the stroke were used to measure social readjustment. The resumptions of first meaningful social activity was the best predictor for life satisfaction in stroke survivors(r=.245, p<.01). The substance of perceived meaningful social activities were job, meeting with friends, hobby and activities for the family. The sum of meaningful social activities (r=.175, p<.01) and occupational rehabilitation (r=.116, p<.05) were significantly related to life satisfaction. There were significant difference in IADL, depression and life satisfaction according to resumption of meaningful social activity. But, occupational rehabilitation was not related to depression. The level of social readjustment was different between occupational rehabilitation and resumption of meaningful social activity. It was 45.7% in the first meaningful social activity and 36.6% in occupational rehabilitation. The related factors with resumption of the first meaningful social activity were that of IADL, depression, illness intrusiveness and cognitive function. And the level of IADL, illness intrusiveness, cognitive function, and age were significantly related to occupational rehabilitation. In conclusion, we suggest that the resumption of the first meaningful activity in stroke survivors is the best predictor of social rehabilitation. Thus, nurses need to work for resumption of meaningful activity as well as occupational rehabilitation.

Purpose: The aim of this study was to investigate the level of resilience and related factors in patients with Parkinson's disease (PD) in Korea. Methods: Data were obtained from 148 patients using the Resilience Scale (RS), Beck's Depression Inventory (BDI), and Spielberger's Anxiety Inventory (AI). Results: The mean scores of the RS, BDI, and AI were $127.7{\pm}21.6$, $12.9{\pm}9.3$, and $41.9{\pm}11.1$, respectively. The RS score was strongly correlated with the BDI score (r=-.531, p<.001) and the AI (r=-.572, p<.001). The resilience was significantly revealed by household income (F=4.002, p=.009) and presence of a hobby (t=-3.300, p=.001). In addition, resilience was significantly correlated with age of disease onset (r=.164, p=.046), years of living with PD (r=-.262, p=.001), and the length of treatment with levodopa (r=-.283, p<.001). From the stepwise multiple regression analysis, the most important factors related to the RS score were the AI score, household income, and length of treatment with levodopa. Conclusion: Understanding these factors is essential for developing effective interventions to improve resilience in patients with PD.

Most of current shopping malls do not satisfy everyone because they present arrangements of goods and suggestions uniformly and comprehensively according to the thinking of their managers. On the other hand not the standard of selection but the comparison of price plays a decisive role of the purchase of goods as similar form each other. When classifying into groups according to generations, gender, income, job, hobby, etc. the propensity of purchase is showed differently and the interest and real purchasing power of the individual is different in shopping malls. It also will maximize the purchasing power of customers to make and implement the sales strategy more quickly as the basis of fashion and season of environmental factors and natural calamity of environmental variable according to the economic principle. This paper concentrates on the design and implementation of intelligent shopping mall that is added the sales strategy according to environmental variable and can not only analysis, update and classify the propensity of purchase continuously but also construct optimal goods automatically.
