In this study we consider a flow line CONWIP system in which two types of product are produced. The processing times of each product type at each station follow an independent exponential distribution and the demands for the finished products of each type arrive according to a Poisson process. The demands that are not satisfied instantaneously are either backordered or lost according to the number of unsatisfied demands that exist at their arrival instants. For this system we develop an approximation method to obtain the performance measures such as steady state probabilities of the number of parts of each product type at each station, mean waiting times of backordered demands and the proportion of backordered demands. For the analysis of the proposed CONWIP system, we model the CONWIP system as a two class closed queueing network with a synchronization station and analyze the closed queueing network using a product-form approximation method for multiple classes developed by Baynat and Dallery. In the approximation method, each subsystem is analyzed using a matrix geometric method. Comparisons with simulation show that the approximation method provides fairly good results for all performance measures.

Targeting people returning to farming and also people preparing for returning to farming, this study analyzed differences in awareness of conflict factors and conflict management focusing on the conflicts experiencing in the process of their movement and settlement process in rural area. In the results, people preparing for returning to farming showed higher awareness of conflicts and also higher necessity of conflict management than people already returning to farming. Also, both groups preferred individual conflict management to structural conflict management. Based on the results like above, the implications can be summarized like below. First, it would be necessary to have programs informing possible conflicts in advance in the process of returning to farming and also relieving psychological anxiety by providing prior-learning to people preparing for returning to farming. Second, it would be necessary to have individual conflict management measures to establish mutual trust and to form community spirit through regular social gatherings between original residents and people returning to farming. Since the effect of conflict management can be maximized only when the structural and individual conflict managements are properly harmonized, it would be necessary to have the structural conflict management which is relatively felt difficult.

Purpose: The researchers reviewed the previous studies on the psychological anxiety and economic damage during the recent COVID-19 pandemic to understand the satisfaction, awareness and attitude of the residents in Jeju, Korea. Research design, data and methodology: 215 samples based on self-reported survey were collected for path analysis focused on controlling variables in demographic characteristics in PLS-SEM using Smart PLS 3.0. Results: The researchers found the Satisfaction with COVID-19 Prevention Measures and the Awareness of Tourism Crisis affect Attitude toward Tourism of the residents with the explanatory power (R² = 0.209). Age was found to be the only significant controlling variable in this model for the Awareness of Tourism Crisis to Attitude toward Tourism. Conclusions: The attitude toward tourism is influenced by the level of satisfaction of the prevention service for COVID-19 as well as the awareness of the crisis. Residents have different level of the tourism crisis awareness by the status of their economic activities while there is no differences in all age groups for satisfaction in the quarantine service. The study suggests that the importance of the public health service should be preferentially concerned for residents to have stable economic activities where the tourism is the major industry.

This study analyzed results of the rounding guidance by applying the nutrition management check list at of the Center for Children's Foodservice Management (CCFM). Totally, 271 foodservices for children (65 institutional foodservices, 53 small scale foodservices, 153 family child care homes) were examined to identify the necessity of implementing a nutrition management strategy, and subsequently creating a priority list for nutrition management improvement measures. Of the 13 items examined in the nutrition management check list for children's foodservices from the Ministry of Food and Drug Safety, 8 performed well, with an overall performance rate of 90% or more. Improvement plans were required for items (all belonging to the menu area) such as 'Post menu on noticeboard at children's foodservice' (62.0%), 'Use the menu planned by dietician' (64.9%), 'Use menu suitable for recipients in children's foodservice' (76.8%), and 'Provide menu to parents' (79.0%)'. In the analysis of service size, the performance rate for 'Use menu suitable for recipients in children's foodservice' revealed a substantially lower result (P<0.01) for institutional foodservices (64.6%), as compared to small scale foodservices (71.7%) and family child care homes (83.7%). Since other check list items, did not show much differences by the service size, we ascertained it pointless to establish separate strategies based on different foodservice sizes.

인지 복합성과 대처 유연성은 심리적 적응에 밀접한 관계를 가진다는 기존 연구에 근거한다면 상담의 주요과정인 역전이 관리능력에도 정적인 영향을 미칠 수 있을 것으로 추론할 수 있다. 본 연구에서는 상담자의 인지 복합성과 대처 유연성이 역전이 관리능력에 미치는 영향에 대해 알아보았다. 본 연구를 위해 서울 및 수도권 소재의 대학생활 상담소, 상담센터, 학교, 병원 등에 근무하는 상담자 128명(여 108명, 남 20명)을 대상으로 하여 설문조사를 실시하였다. 연구 결과, 상담자의 인지 복합성 수준에 따른 역전이 관리능력에는 차이가 없는 것으로 나타났으나, 상담자의 대처 유연성의 수준에 따라서는 역전이 관리능력에 유의미한 차이가 있었다. 또한 중다회귀에서 역전이 관리능력에 있어서 대처 유연성이 인지 복합성에 비해 보다 많은 영향을 미치는 것으로 나타났다. 이는 역전이 관리능력을 함양하기 위한 방안으로 상담자의 대처유연성을 향상시키는 것이 중요함을 시사하며 이에 초점을 둔 상담자 훈련 프로그램 개발이 필요하다.

Background: The purpose of this study was to identify role ambiguity of comprehensive nursing care unit nurses. Methods: A concept analysis method by Walker and Avant was used to understand role ambiguity of comprehensive nursing care unit nurses. Results: The antecedents of role ambiguity of nurses at comprehensive nursing units were shortage of nurses, unclear admission criteria, and demands for customized nursing care according to severity. Attributes include ambiguity in role delegation, patient placement ambiguity, and professional ambiguity among nursing staff. The consequences were diminished job satisfaction due to excessive workload, difficulty in resolving role ambiguity due to the lack of work analysis studies, and poor outcome of nursing indicators. Conclusion: Improvement of nationwide awareness for comprehensive nursing care unit is required. Clear division at scope of practice for nursing staff in accordance of each medical institution's characteristics is essential. Nurses at comprehensive nursing care unit should understand nature of role ambiguity that occurs as they work in large groups. Nurses should promote communications between nursing staff and they must have volition to improve status quo. An additional research of comprehensive nursing care on the causes of role ambiguity in the practice of nursing care for ward nurses is needed, and management measures should be sought at the organizational level.
