Recently the open innovation is considered as one of the important issues for the survival strategy of a company in the industry. There have been several researches and practices on this topic. However, previous researches are mainly focused on the study of successful cases and some statistical analyses on the relationship between the open innovation and its performance. There are rare researches on the hindrance factors in the practical level. This paper tries to find some hinderance factors for the open innovation in Korean large-scale companies based on the WFGM(Want-Find-Get-Manage) model proposed by Gene Slowinski(2006). Especially this research focused on each processes of open innovation by in-depth interviews for two representative large companies in Korea. From the result of this research we come to know that the critical hindrance factor in the WANT step is the uncertain definition of the necessary technologies for the company. Issues on establishing and maintaining the innovation network are in the FIND step. Technology evaluation, technology introduction channel and technology copying issues are in the GET step. Communication issues, technology feasibility and lack of competition are in the MANAGE step. This paper finds some hindrance factors in each process step of open innovation, which gives some implications for the companies that want to adopt open innovation.

Purpose: The purpose of this study was to develop a Coping Scale for Infertility-Women (CSI-W). Methods: The initial items were based on an extensive literature review and in-depth interviews with seven infertile women. Forty-three items were derived from a pilot survey. Data were collected from 216 women who had experienced intrauterine insemination (IUI) and in-vitro fertilization (IVF) more than once. The data were analyzed to verify the reliability and validity of the scale. Results: Seven factors containing 28 items (four factors containing 17 items for active coping and three factors containing 11 items for passive coping) were extracted from the exploratory factor analysis to verify the construct validity. The four factors of active coping were confrontation, self-control, seeking social support (spouse), and seeking social support (colleagues and experts). The three factors of passive coping were distancing, escape, and avoidance. These items were verified through convergent, discriminant, and concurrent validity testing. The internal consistency reliability was acceptable (active coping: Cronbach's α = .78; passive coping: Cronbach's α = .81). Conclusion: As its validity and reliability have been verified through various methods, the CSI-W can contribute to assessing the coping strategies of infertile women.

Objectives: The purpose of this study was to investigate factors affecting the drinking behavior in high school students. Methods: There were 620 subjects who were first and second graders of seven high schools in Daegu. This study used Sinhaengwoo (1998)'s drinking behavior scale, Rowlison and Felner (1988)'s stress scale, Kovacs (1981)'s children's depression inventory, Rosenberg (1965)'s self-esteem scale. The data were analyzed by descriptive statistics, Pearson's correlation coefficient, and stepwise multiple regression using SPSS/win 18.0 program. This study was approved by the Institutional Review Boards (IRB) of the Keimyung university hospital(No. 12-112). Results: The mean score for drinking behavior in high school students was 23.1points. Factors influencing drinking behavior in high school students were identified as self-esteem(t=-3.67, p<.001), stress(t=6.79, p<.001), school types(t=4.02, p<.001), sex(t=-3.67, p<.001). These factors explained 27% of drinking behavior reported by high school students. Conclusion: The results indicate which factors are majors influencing drinking behavior in high school students. Therefore, self-esteem enhancement could be considered as an effective strategy to reduce the drinking behavior in high school students.

Purpose: The number intelligent homecare products are focused on the development of technology, resulting in a lack of realistic environments or requirements for consumers. The purpose of this paper is to define the consumer and context for intelligent homecare products and to develop a usability evaluation scale. Research design, data and methodology: For this study, first, consumer and contexts related to intelligent homecare products were analyzed through literature review. Second, the primary usability evaluation factors were derived for intelligent homecare products by collecting the factors related to usability evaluation and conducting in-depth interviews with experts. Third, the second usability evaluation factors were derived through survey and statistical analysis based on the derived usability evaluation factors. Results: As a result, users of intelligent homecare products were classified as primary users and secondary consumers and six related contexts. The usability evaluation scale was established with four factors - Functionality, Error, Convenience, and Emotion - and 13 items. Conclusions: This study can be the basis for developing and distributing products that meet the consumer environment and requirements related to intelligent homecare products that will contribute to securing the competitiveness of companies and developing the technology and service value of related industries.

Purpose: Small-scale construction sites have insufficient systematic safety management activities, and due to the characteristics of the construction site, the production structure is complex due to external environmental factors, and the risk of construction equipment is very high. We would like to propose a checklist method among practical risk assessment techniques that can derive risk factors for disaster prevention at small construction sites and reduce disasters. Method: Risk factors were derived by analyzing literature research and disaster cases, and detailed work for a checklist of risk assessment suitable for small-scale construction sites was classified based on risk factor items. Result: Hazard factors were divided into 6 major categories, and 29 detailed types of work were classified based on actual work types, and 80 detailed works were classified accordingly. Conclusion: By arranging risk factors suitable for small-scale construction sites according to the classification system, the lack of expertise in the construction site can be supplemented, and risk factors can be derived more easily and disaster reduction can be expected through establishment of safety measures.

The Purpose of this study was to identify characteristics of fatigue and the relationship between fatigue and related factors in patients on hemodialysis. This study was a survey study using a cross-sectional design. The subjects for this study were 101 patients on hemodialysis who were registered in the six hemodialysis clinics among a total of eleven clinics in Seoul. The period of data collection was from February 28, 1995 to May 2, 1995. Data were collected through an interview with a structured packet and the physiological data. The tools used in this study were the Visual Analogue Scale-Fatigue developed by Lee et al(1990) and translated by Lee(1991), the fatigue interview schedule developed by this researcher, Zung's self rating depression scale(Zung, 1965), the self-efficacy scale developed by Sherer et al(1982) and the Norbeck Social Support Questionnaire(NSSQ) translated by Oh(1984). The collected data were analyzed using descriptive statistics(mean, standard deviation, frequency, range), Pearson correlation coefficients and Stepwise multiple regression. The results were as follows ; 1. Characteristics of Fatigue of hemodialysis patients : 1) 79 of 101 hemodialysis patients complained fatigue. 2) The mean fatigue score as measured by the VAS-F was 36.2mm. 3) The mean duration of fatigue was 2.9 hours 2. Characteristics of fatigue related factors : 1) The physiologic factor which included Hgb, Hct, BUN, creatinine, potassium and interdialytic weight gain deviated from normal range. 2) The psychological factor which included depression and self-efficacy was about the same level as for patients with other chronic diseases. 3) The environmental factor which included social support had wide variation. 3. The relationship between fatigue and related factors : 1) Interdialytic weight gain in the physiologica factor was the only valuable with fatigue （p＜.05） 2) The relationship between fatigue and the psychological factor of depression showed a positive and strong correlation（p＜.05）. According to the findings of this study, fatigue was highly correlated with the depression. This indicates that nurses should try to assess and control psychological factors when patients complain of fatigue rather than just considering physiological factors. Nursing has to develop effective nursing interventions to reduce fatigue in patients with chronic diseases using the relationship between fatigue and physiological, psychological and environmental factors.
