Background: Presenteeism is closely related to work performance, work quality and quantity, and productivity at work. According to the job demand-control-support model, job demand, job control, and support play important roles in presenteeism. The present study investigated job characteristics profiles based on the job demand-control-support model and identify the association between job characteristics profiles and presenteeism. Methods: This secondary data analysis used the Sixth Korean Working Condition Survey, a nationwide cross-sectional dataset. The study included 25,361 Korean wage workers employed in the workplace with two or more workers. Participants were classified into four job characteristics profiles based on the job demand-control-support model, using latent profile analysis, and logistic regression was performed to examine the association between study variables. Results: Overall, 11.0 % of study participants reported experience of presenteeism in the past 12 months. Age, sex, location, monthly income, shift work, work hours, health problems, and sleep disturbances were significantly associated with presenteeism. The rate of presenteeism was the highest in the passive isolate group. The passive collective, active collective, and low-stain collective groups had a 23.0%, 21.0%, and 29.0% lower likelihood of experiencing presenteeism, respectively, than the passive isolate group. Conclusions: The job demand-control-support profiles and the risk of presenteeism were significantly associated. The most significant group that lowered the experience of presenteeism was the low-strain collective group, which had a low level of demand and high levels of control and support. Therefore, we need a policy to reduce job demand and increase job control and support at the organizational and national levels.

This study investigated the isolation hypothesis and the buffer hypothesis of Demand-Control-Support model in relation to activity satisfaction and psychological well-being. The subjects were 300 elderly women participating in productive activity for example paid work, voluntary activity, and grancdhildren care. This research tested four hypotheses concerning the DCS model. Is there support for the isolation hypothesis, such that the lowest level of activity satisfaction is experienced by the elderly women working in an isolation situation(high demand-low control-low support)? Is there support for the isolation hypothesis, such that the lowest level of psychological well-being is experienced by the elderly women working in an isolation situation(high demand-low control-low support)? Is there support for the buffer hypothesis, i. e. interaction between demand, control, and support, indicating a buffering effect of support on the negative impact of high strain on activity satisfaction? Is there support for the buffer hypothesis, i. e. interaction between demand, control, and support, indicating a buffering effect of support on the negative impact of high strain on psychological well-being? Major results of this study were as follows. and were supported. Activity satisfaction and psychological well-being of the elderly women in isolation situation was the lowest among the sample. was supported that family support level buffered the negative impact of high strain on activity satisfaction. But was not supported. Only main effect of demand level was showed on psychological well-being.

Much research has focused on the conflict and balance between work and family. Yet few studies examine how women feel in balancing these two roles. In that regard, this study examines how married working women feel balanced between work and family as well as the levels of support availability/demand that exists. The level of sense of balance regarding work-family is average. Sense of balance is related to age, income, work hours, size of workplace, numbers of family friendly policies, the family's attitude to woman's work, and the level of balancing strategies used. The demand for support is higher than the availability of support. Both factors are related to working hours and balancing strategies, etc.

Forecasting of electricity demand have difficulty in adapting to abrupt weather changes along with a radical shift in major regional and global climates. This has lead to increasing attention to research on the immediate and accurate forecasting model. Technically, this implies that a model requires only a few input variables all of which are easily obtainable, and its predictive performance is comparable with other competing models. To meet the ends, this paper presents an energy demand forecasting model that uses the variable selection or extraction methods of data mining to select only relevant input variables, and employs support vector regression method for accurate prediction. Also, it proposes a novel performance measure for time-series prediction, shift index, followed by description on preprocessing procedure. A comparative evaluation of the proposed method with other representative data mining models such as an auto-regression model, an artificial neural network model, an ordinary support vector regression model was carried out for obtaining the forecast of monthly electricity demand from 2000 to 2008 based on data provided by Korea Energy Economics Institute. Among the models tested, the proposed method was shown promising results than others.

This study tested the path model with regard to how certain variables (control attribution, demand-control-support of activity, and control strategy) affected the elderly workers' subjective well-being(swb). In the path model, the exogenous variables were internal and external control attribution. We used demand-control-support of activity, and primary and secondary control strategies as mediating variables. The endogenous variable was each elderly worker's swb. Study participants were 205 elders participating in an "education activity". We used descriptive statistical analysis, Pearson's correlation and hierarchical multiple regression to examine data collected from structured interviews with the participants. Path analysis revealed the followings: First, secondary control strategy was the strongest predictor of participants' swb but internal control attribution, demand of activity, and support of activity also positively affected participants' swb. Second, internal control attribution indirectly affected the participants' swb. Finally primary control strategy negatively affected on the participants' swb.

The growth of the fashionable hanbok market has led to a significant increase in the number of entrepreneurs or prospective entrepreneurs with small hanbok businesses. To develop the hanbok industry, the public sector is developing and providing education and support programs to enhance the competencies of individual hanbok brand entrepreneurs. This study conducted a survey of 213 subjects such as business operators, workers, and prospective workers in the changing hanbok industry. This study investigated their hanbok education experiences as well as future demands for education and public support programs. To explore differences based on individual characteristics, this study measured such characteristics using entrepreneurial orientation as well as the artistic and entrepreneurial competencies important in running a hanbok brand and analyzed the relationship demand for education and public support. Hanbok brand worker characteristics were classified into four groups based on individual characteristics: "traditionalist," "entrepreneur," "opportunist," and "businessman." Differences existed in terms of detailed education experience and demand as well as demand for public support, depending on the group. The results of this study contribute to development of hanbok curriculums that consider individual characteristics, the effective incubation of new and prospective hanbok brand entrepreneurs, as well as the research on founding small-scale fashion businesses.

This study focused on the generational change of elderly people in the future based on the changes of aging background and household structure. After 2025, when the growth rate of aging rapidly becomes prominent, the generation born before 1961, the baby boomers who were in their youth after the country's liberation, will replace the current elderly generation. This means that the characteristics and values of living of the elderly will change and not pass on to the future, and that the demand for housing will also be different. The purpose of this study is to predict the future elderly housing demand and to find out the issues of housing support for elderly people and necessary institutional support items. For this purpose, the preliminary elderly people are surveyed and analyzed for their present housing condition, perception of old age, housing plan, welfare facilities and demand for living services. The results of this study are meaningful in laying the groundwork for predicting the demand for housing and living support of the elderly in the future and proposing suggestions and preparing related systems.

This study aims to examine the family awareness and the demand for a group-based healthy family support program for current and former residents of a residential care institution, and to provide information to be utilized in the development of a comprehensive group-based family support program. To support this study, 1:1 interviews were conducted. The interviews focused on the adolescents' perception of their own families, perception of family in general, demand for a group-based healthy family support program, etc. The results of the interviews are as follows. First, as for the perception of their own families, the 'happiest' and 'saddest' experiences they reported were related to their own families for both the current and former resident adolescents of the institution. Second, as for the perception of family in general, both groups defined a healthy family as a family with members who 'help one another in times of difficulties and live happily in harmony together'. Third, regarding the educational contents that are essential to the establishment of a healthy family, a majority of the current residents answered cooking, yet a majority of former residents mentioned more practical education-such as the role of parents, child education, asset management, human relationships, and self worth enhancement, etc.

The purpose of this study was to measure the depressive symptoms and to determine their relationship with job stress content and social support of manufacturing male workers. A total of 428 male workers were surveyed from July 1 to August 31, 2017 using self-administered questionnaires. For the results, the rate of the depression group was 25.1%. In terms of the CES-D scores by job stress contents, CES-D scores were higher in the high job demand group than in the low group and higher in the low job control group than in the high group. In terms of CES-D scores by social support, CES-D scores were higher in the low supervisor support and coworker support group than in the high group. CES-D scores showed a significant positive correlation with job demand but a negative correlation with job control, supervisor support, and coworker support. In terms of hierarchical multiple regression analysis, higher job demand was associated with lower job control, and lower support of supervisors and coworkers gave high depression scores. Explanatory power for depression score significantly increased by 18.4% according to job demand and added job controls. Explanatory power increased by 14.1% with the support of supervisors and coworkers. The above results suggest that the level of depressive symptoms is highly correlated with job demand, job control, and support of supervisors and coworkers.
