여러 개의 작업이 동시에 작동 할 때 서로 다른 작업에서 특정한 로봇이나 장치를 사용하기 위하여 상대방의 작업이 끝나기를 기다리는 상태를 교착상태라 하며 생산공정에서는 효율성과 경제성 제고에 가장 중요한 문제 중 하나다. 지금까지 이러한 교착상태 확인은 도달성(reachability)기법이나 서브넷(Subnet)으로 분리하여 분석하는 기법 등이 가장 많이 사용 되었으나, 분석에 필요한 시간과 노력, 복잡성과 효율성에 있어서 효과적이지 못한 단점을 가지고 있다. 본 연구는 페트리넷(Petri Net)에서 모든 플레이스(Place) 간의 관계를 나타내는 추이(Transitive)행렬을 이용하여 교착상태가 나타날 가능성이 있는 자원공유 플레이스(Place)를 분석하여 교착상태를 검증하는 정책을 제시한다. 이를 위하여 교착상태를 확인할 수 있는 자원공유 플레이스의 관계를 정의하고, FMS(Flexible Manufacturing System) 모델을 이용하여 제안한 알고리즘의 성과를 검증한다.

This study applied self-determination theory to investigate the relationships between volunteers' perception of supervisors' autonomy support, volunteering motivation, and persistence intentions among collegiate students. Collegiate volunteers(n=515) involved in volunteer activities completed measures of supervisors' autonomy support, 5 forms regulation, and persistence intentions. Bivariate correlations indicated that volunteer motivation demonstrated an ordered pattern of relationships, such that adjunct points along the regulatory continuum would be more positively associated with on another than distal points. Analyses using structural equation modeling revealed that supervisors' autonomy support was positively related to more autonomous motivation(intrinsic motivation and identified regulation), while was natively associated with amotivation. Amotivation was negatively related with persistence intentions, and more autonomous motivations(intrinsic and identified) predicted grater intentions to continue with volunteer activity for next 6 months. The findings are discussed in light of the self-determination theory.

This study investigated the effects of job demand-resource variables that appear in a special organizational environment such as a hospital on job burnout and job engagement using the job demands-resources model of Schaufeli & Bakker(2004). And also the study investigated to verify discriminatory mediating roles of emotional labor strategies in the process. The main finding of this study was as follows: Job demands-resources showed a positive relationship in the job burnout and job engagement, and job demands induced surface acting and job resources induced deep acting. However, deep acting showed a positive relationship to job engagement, and surface acting showed a negative relationship with job burnout unlike in previous study results, which was not significant. The results of verifying the meditation model through Boostrap showed that since the two indirect effects were not significant, the meditating role of emotional labor strategies was not verified in the effects of job demand-resource levels on job attitudes, including job burn out and job engagement.

The purpose of this study was to examine the influences of employees' volunteer activities on organizational behavior and the mediating effect of positive psychological capital in the relationship with organizational commitment, and the mediating effect of perceived organizational support adjusted through positive psychological capital. The collected 347 survey data were analyzed using SPSS 21.0 program. As a result, the mediating effect of positive psychological capital and the moderating effect of perceived organizational support were found. It was found to have a mediated moderating effect of perceived organizational support. Further research on extended concepts of organizational behavior of employee volunteers is needed.

This study was to analyze whether volunteer motivation represents a mediated effect in the relationship between social support and multicultural acceptance by university students as a late adolescent. Among the students attending a university located in North Chungcheong Province, 256 participants have experienced volunteer work. Data analysis conducted multiple regression analysis using SPSS and analysis showed that social support of university students affected multicultural acceptance and that volunteer motivation in their relationship between social support and multicultural acceptance was fully mediated. Based on these results, it has revealed a path that the social support of university students affects multicultural acceptance through volunteer motivation. Therefore, in order to gain social support, university students should improve their ability to maintain a positive view of interpersonal relations and to cope with conflicts efficiently. They will also have to strengthen self-directing capacity in order to increase the level of motivation for volunteer participation.

The purpose of this study was to identify the effect of job resources of hospital workers on presenteeism and to verify the mediating effect of job embeddedness based on this. Participants included 301 hospital workers form hospitals located in B city. Date was collected form July 10 to August 10, 2023. The collected data were analyzed by frequency analysis, descriptive statistics, Pearson's correlation coefficient, Baron and Kenny's three-step hierarchical regression and Sovel's test method using the SPSS 26.0 program. In this study, it was found that there was a correlation between job resources, job embeddedness and presenteeism of hospital workers, job resources and job embeddedness influenced negatively on presenteeism, and it was confirmed that job embeddedness partially mediated in the relationship between job resources and presenteeism. Based on this, in order to reduce presenteeism of hospital workers. it was suggested to improve job integrity by providing sufficient job resources institutionally an administratively and providing continuous educational opportunities.

This study explores the factors that moderate the impact of competitive strategy on resource sharing in order to explain why existing empirical research has not shown statistically significant results. We test the hypothesis that competitive strategy pursuing low-cost rather than differentiation increases resource sharing and analyze how the relationship between competitive strategy and resource sharing changes when diversification, interconnectedness, centralization of authority, and resource level are entered into the equation as moderating variables. According to the results, competitive strategy doesn't affect resource sharing alone, but it has significant effects on resource sharing when it is combined with interconnectedness, centralization of authority, and resource level, except for diversification. This means that low-cost strategy increases resource sharing under the conditions of high interconnectedness, more centralized authority, and low resource level. The prior discussions have focused on the willingness or intentions of resource sharing without considering the abilities or possibilities. Our findings indicate that resource sharing could be better predicted by using moderating variables reflecting the abilities or possibilities. The contribution of the study is that we discover and complement the vulnerability in the logic of resource sharing.

The purpose of this study was to examine relationships among information resources use, problem solving ability, nursing information literacy competency in general hospital nurses. The descriptive correlational study design was used. The data were collected from 141 nurses working in the two general hospital located G city using self-reported questionnaires. Data were analyzed using SPSS statistics 20.0 program. As results of multiple regression analysis, the factors affecting nursing information literacy competency were problem solving ability and electronic information resources use. And this model could explain 38.0%(F=43.73, p<.001). Considering the findings from this study, nurses need to develop problem solving ability and electronic information resources use improvement program for them.

오늘날의 정보세계에서 정보 자원은 유형이 빠르게 다양화되고 있을 뿐만 아니라 여러 자원과 관계를 맺고 있다. 이러한 상황에서 자원을 평면적으로 보여주는 기존의 MARC 기반 검색시스템은 이용자의 요구를 충족시키기 어렵다. 이에 따라 본 연구의 목적은 서지 자원의 다양성과 관계성을 나타낼 수 있는 FRBR 모델의 저작 개념을 활용하여 새로운 검색시스템을 개발해 보는데 있다. 연구 대상은 성균관대학교 존경각의 고서서지시스템으로 해당 시스템의 서지레코드 중 청구기호는 저작 개념을 반영하고 있다는 특징을 지니고 있다. 본 연구에서는 이러한 점에 주목하여 청구기호를 통해 저작 식별자를 생성하고 각 서지레코드에 할당함으로써 검색결과가 저작을 중심으로 표현되는 실험 시스템을 개발하였다. 저작 단위로 검색결과를 표시하도록 시스템을 구현한 결과 이용자가 키워드 검색을 한 뒤 처음 마주하는 검색결과의 수가 눈에 띄게 감소하였다.
