This study investigates the effects of three types of person-environment fit, i.e. POF, PJF(ability) and PJF(needs), on effectiveness variables and the mediating effect of work motivation in SMEs. The data were collected from 211 employees who work for SMEs. Results of structural equation modeling(SEM) analyses demonstrated that PJF(ability) was significantly associated with task performance and turnover intention, while POF and PJF(needs) were significantly associated with turnover intention only. PJF(needs) and PJF(ability) have the positive impact on intrinsic motivation, PJF(ability) also has the positive impact on external and identified motivation. We also analysed mediating effects using Process macro. Results demonstrated that intrinsic motivation mediated the relationship between POF, PJF(needs), PJF(ability) and task performance. The relationship between PJF(ability) and task performance was mediated by external motivation. Based on the results, theoretical and practical implications are derived. Also suggested are methodological limitations and future research directions.

The subjects of this study were 762 hospital employee selected from ten of university hospitals in Seoul, Incheon, and Kyung Gi which are doing an education and training, and conducted a self-completion questionnaire. As a result of study and plan for raising the effectiveness were indicated following statements. Firstly, according to the general specific, training effectiveness was appeared similar. So, it requires suitable alternatives to make educational programs. Secondly, according to analysis of education and training necessity, achieving a goal for education and training have difference. it needs to be scientific analysis about necessity of education and training. Thirdly, when contents of education and training program are satisfied to educatee and fit for them, thinking of education and training effectiveness is higher. Therefore, establishing the goal of education training is concrete, realistic, and measurable for increasing learning motivation. Next to, thinking of education and training effectiveness is higher, when education and training person in charge taught to educatee very well, and they were satisfied about teaching. Consequently, they who nourishment of education and training person in charge within company have to improve their ability. And then, when educatee fit for teaching technique and satisfied about it, thinking of education and training effectiveness is higher. So, education and training were tried to find many of technique for fitting the desire of educatee. Sixth, the more education and training environment is satisfactory, the more educatee have high thinking of education and training effectiveness. CEO in hospitals have to think about many-sided solution for employee. Seventh, the more education and training have correct achieving organizational goal, the more educatee have high thinking of education and training effectiveness. Accordingly, hospital management should make up for education and training system. Then, thinking of education and training effectiveness is higher, when education and training measure an effect, and reflect to personnel management and assessment of an employee's performance. It should be the feedback for using information which is planning education and training. In conclusion, when result of measurement of education and training reflect to make a education and training plan, thinking of education and training effectiveness is higher, and result of measurement of education and training should reflect to make a education and training plan.

The aim of this study is the development of a fee - based model day care center for the elderly by inquiring into the current condition of facilities in America and in Korea, and in surveying the opinion of domestic elderly about day care facilities. A field trip to U.S. day care services was held between July 5 and July 15 in 1997, and an on-the-spot study for domestic facilities took place during March in 1998. Our research reveals that the overall supply of day care facilities can not meet future demand in terms of quality and quantity. Therefore a model must be created for day care centers of a that consists of a director from a professional group. an adequate environment, and a standardized in order to offer a qualified public health service linked to the home and community in Korea. The director of a day care center is a critical variable in determining the quality of service. Professional skills related to the needs of the elderly and the person's quality of service should be considered in appointing director for the center. This study belleves that a professional nurse should be the director of a day care center. The operating environment of a day care facility should be made up of considerable space comparable to the number of residents, should be in a comfortable and safe location, and should have equipment that provides a qualified, safe service to the elderly. Our model is designed for 20 persons and allocates 4 Peng per person. This model is comprised of a reading room. a craft room, a health room, a room for physical therapy, a dining room, a staff office, and a multi -purpose room connected to other rooms. Day care service should be a comprehensive service program meeting the multidimensional needs of the elderly. A comprehensive service program needs a team of various professionals made up of the elderly family, participants, nurses, social workers, physical therapists, nutritionists, and medical doctors. The program will also include health care service, physical therapy, speech therapy. diet, occupational therapy, transportation service, health and an education program, etc. In conclusion, a model of a day care center is developed with the following components: a professional director and an environment and program, that considers the physical, mental, and social characteristics of the elderly. A model should also motivate self-reliance self-fulfillment in the elderly in order to fulfill their health needs and to prevent isolation from society and mental depression. Furthermore, This facility will be a beneficial factor in reducing a family's burden on caring for the elderly that includes unnecessary hospital expenses. The following is a suggestion based on results this study: A service program should be developed to fit the conditions of the elderly in Korea by specifically analyzing the needs of the elderly.

The purpose of this study is to examine which job-related factors are associated with presenteeism, which is defined as attending work while ill. Although presenteeism is a relatively new concept in academic research, it should be regarded as an important social issue in that presenteeism threatens employees' job prospects and quality of life as well as it causes loss of work productivity. I analyzed a cross-sectional survey of 24,571 wage workers over 15 from the fourth wave of the Korean Working Conditions Survey in 2014. Five logistic regression models were analyzed on experience of presenteeism, and work hours and private life, occupational environment, job insecurity, rewards and welfare were assessed as key predictors of presenteeism. I found that 1) work hours with bad fit with private life, 2) high level of work time-pressure, and low job satisfaction 3) job insecurity, and 4) low benefits are associated with experience of presenteeism. The findings are fairly consistent with the theory of job-person mismatch, which explains that workers tend to preserve their personal resources by going to work while ill (presenteeism) when job demands or work conditions do not match with their level of personal expectation and, thus, workers are afraid of loss of personal resources. Presenteeism influences worker's long-term health and quality of life negatively as well as causes serious social costs. Therefore, we need organizational efforts to prevent the negative effects of presenteeism on society as well as workers.

Recent information technology achieves remarkable progress in almost all areas where it can be applied. However, this technology also causes technostress, such as fear and pressure to individuals, due to events, such as the threat of job loss. This technostress is becoming an important factor that can affect user performance and productivity in future society where information technology will be the focus. This kind of stress should be studied considerably in academic and practical applications. The effects of technostress on individual performance remain ambiguous. Therefore, academic research is needed to prove these effects. This study aimed to clarify the direct and indirect effects of technostress on information technology end-users. We developed a research model that integrates innovation resistance and technostress theory through previous studies and analyzed the questionnaire of 317 people. The PLS structural equation model and the study results of Baron and Kenny (1986) indicated that rapid change, connectivity, reliability, and complexity are crucial factors affecting the technostress of information technology. Technostress was analyzed indirectly only through innovation resistance, which affected the performance of end-users. This study will provide new implications for the relationship between technostress and performance or productivity in the IS field.

Sales force automation (SFA) technologies are increasingly used to support customer relationship management (CRM) strategies. However, the popular press reports mixed results among companies incorporating SFA technologies and the previous studies have less interested in relationship quality between sales person and customer as an outcome of SFA. Actually the improved quality of the salesperson-customer relationship may be the most important outcome of SFA usage. This outcome is especially meaningful in today's marketplace given the increasing focus placed on customer retention and other customer related performance such as customer lifetime value. Therefore, this study seeks to further examine the impact of SFA usage within two different firms using SFA technologies to examine the impact of SFA usage on both customer relationship quality and sales performance. Additionally, the moderating roles of perceived managerial support and salesperson experience on the outcomes of SFA usage are examined. The results shows that direct effect of SFA usage on performance was not significant but highlight the mediating role of customer relationship quality in the SFA usage - sales performance relationship. Also, this research examines a number of moderating effects of both management supports for SFA and salesperson's sales work experience. The results indicate that management support has a significant direct influence on relationship quality and salesperson performance, but not a significant moderating effect on the relationship between SFA usage and the outcomes (relationship quality and performance). Thus moderating effects were not supported but find significant main effects. First of all, finding of this study suggest that a formula for successful SFA implementation must be one that highlights a SFA usage → relationship quality → sales performance sequence. This means when sales person use SFA they must build relationship with customer first then will return some long term performance. Second, the implications of not considering the introduction of big technology initiatives in terms of fit within the company's culture, strategy, structure, and environment may in many cases be quite noteworthy. Therefore, the launching of a new technology in the firm, such as SFA, may have a nonlinear impact upon overall firm performance, depending on the presence of other complimentary resources and capabilities. Finally the authors offer a number of implications for research and practice, and suggest directions for future SFA research that may further improve our understanding of this increasingly relevant topic.

Due to the continuous unemployment problem, the number of jobs is gradually decreasing, and entrepreneurship is emerging as an alternative. This is because, despite the government operating various start-up support programs to build a start-up-friendly culture, young entrepreneurs cannot endure the valley of death and disappear. Therefore, through this study, we intend to provide implications by analyzing the impact on Entrepreneurial satisfaction, which is essential for continuously running a business, and life satisfaction, which can act as a social awareness. This study was conducted with 573 non-wage workers who belonged to the founders among the participants of the 'College Graduation Occupational Migration Path Survey(GOMS)' survey provided by the Korea Employment Information Service. In order to analyze the relationship between entrepreneurial competency and job fit, Entrepreneurial satisfaction, and life satisfaction, the analysis was conducted using the SPSS 23.0 program. The main research results are summarized as follows. First, entrepreneurial competency has a positive effect on Entrepreneurial satisfaction and life satisfaction. Second, job fit indicates a moderating role in the relationship between entrepreneurial competency and Entrepreneurial satisfaction. Third, start-up satisfaction appears to have a partial mediating role in the relationship between entrepreneurial competency and life satisfaction. Fourth, as a result of analyzing the difference between groups according to the type of start-up(single/partnership), the group that worked together showed higher Entrepreneurial satisfaction and life satisfaction. The main implications of this study are: First, in order to increase the Entrepreneurial satisfaction and life satisfaction of university graduates who are the subject of the study, it will be necessary to design a program that can diagnose and enhance the entrepreneurial competency of students at the university level. Second, entrepreneurial competency is a basic intrinsic factor that founders must have, and it should act as an important evaluation factor when selecting founders for support programs from start-up support organizations as well as founders. Third, it is necessary to maintain mutual trust by documenting problems (positions, wages, management rights, distribution of profits, etc.) that may occur in joint ventures with objective data. Fourth, it is necessary to establish an environment in which the MZ generation, armed with the challenging spirit and creativity, can continue to take on challenges even if they fail.

In this study of visitor place attachment to parks, Scannel and Gilford considered the dimensions of place attachment, and proposed the theoretical framework of PPP(Place, Person, Process) that should be systematically studied from the perspective of person, place and psychological processes. According to Scannel's theoretical basis, this paper puts forward the hypothesis of a structure model of place attachment. In the model, the five independent variables of people, places, cognition, emotion, and behavior have influenced the dependent variable of place attachment. The questionnaire was conducted on 18 neighborhood parks in Kunming, China, and the residents of the 5 neighborhood parks in Daejeon, South Korea. A total of 1,645 valid samples of the questionnaire survey were collected. Through confirmatory factor analysis(CFA) results of the inspection of the various elements, it was shown that the reliabilities of 6 latent variables, such as people, places, cognition, affection, behavior and place attachment, which were composed with the observed variables(30 observed variables in Daejeon, 19 observed variables in Kunming), were all above 0.7 and the data were fit for this study. The hypothesis test results found that the physical environment of the neighborhood parks such as a comfortable environment, pleasant road and convenient facilities would increase the rate of visitors coming back. From the park management perspective, to increase the amount of visitors to the park, the park should increase visibility, provide more organized, varied activities and meetings, or special exhibitions according to the particular characteristics of the individual park, to increase awareness of the park. From the park visitors' psychological perspective, visitors are seeking to enjoy the park facilities and environment not only to bring physical relaxation, but also to bring about a psychological cure. With the commonality of attachment structure between the two countries, to improve the place attachment of neighborhood park visitors, collecting regularly visitor feedback will facilitate the sustainable development of neighborhood park attachment.
