본 연구는 리더의 나이에 따라 집단 의사 결정이 어떻게 달라지는지 알아보고자 하였다. 연구 결과, 나이 많은 리더가 나이 적은 리더에 비해 토론 중 발언 비율이 높았으며, 나이 많은 리더가 속한 집단의 결정 정확률이 더 높았다. 또한 리더의 나이가 많은 경우, 집단 구성원들은 리더의 집단 대표성과 발휘된 리더십을 더 높게 인식하고 있었다. 한편, 리더의 나이가 집단 의사 결정에 끼치는 영향은 리더 선출법에 따라 달라졌다. 리더의 나이가 적은 경우에는 체계적인 방법으로 선출된 리더 집단의 토론의 질이 높게 나타난 반면, 리더의 나이가 많은 경우에는 무작위로 선출된 리더 집단의 토론의 질이 높게 나타났다. 이와 같은 결과는 리더가 소유한 권력 기반의 차이에서 비롯된 것이라 추론할 수 있다.

본 연구는 주로 의사결정과제를 통해 검증되어왔던 무작위적 리더 선출 방법의 우수성을 실제 수행과제로 확장시켰고, 리더 선출 방법과 집단 효능감의 집단수행에 대한 상호작용효과를 살펴보았다. 2(리더 선출 방법: 공식적/무작위적) × 2(집단 효능감: 저/고) 피험자간 실험설계를 통해 집단수행에 대한 영향을 검증했다. 연구 결과, 리더 선출 방법의 주효과가 유의하여 공식적으로 리더가 선출된 집단보다 리더가 무작위적으로 선출된 집단의 수행이 유의하게 높았다. 또한, 두 변인 간의 상호작용이 유의하였는데, 집단 효능감이 낮을 때는 리더가 공식적으로 선출된 집단과 무작위적으로 선출된 집단 간의 수행차이가 유의하지 않았으나, 집단 효능감이 높을 때는 리더가 공식적으로 선출된 집단보다 무작위적으로 선출된 집단의 수행이 유의하게 높았다. 본 연구의 결과는 높은 집단 효능감이 집단의 수행에 긍정적인 영향을 주기 위해서는 리더가 집단의 사회정체성을 손상시키지 않는 방법(예. 리더와 구성원의 차이점을 부각시키기 보다는 동질성에 대한 지각을 높이는 방식)으로 선출되어야 한다는 점을 제안함으로써 조직과 작업 현장에 기여할 수 있다. 향후에 본 연구를 작업 팀으로 확장하여 연구할 필요성을 논의하였다.

The naval combat system is a distributed system in which various subsystems are integrated and operated together. The integrated management system(IMS) is a software system for systematically and consistently managing the application software which control and operate various devices in such a combat system. Since the malfunction or failure of such an IMS can disable the entire combat system, the IMS is more important than other application software of the combat system. In this paper, we propose a method to guarantee the stable and correct operation of the combat system. To this end, we propose a redundancy scheme composed of one leader and several followers so as to tolerate the failure situation of the IMS. We also propose a leader selection algorithm to select a new leader when the leader fails and can no longer perform its role. To verify the validity of the study, we verify the fault tolerance behavior of the system and the accuracy of the leader selection algorithm.

This study has been attempted using the Q methodology to clarify leader type of nurse managers that head nurses and general nurses recognize, and to clarify its relative relation. Sixty-three statements were extracted through interviews with general and professional people interested in the subject of nurse leaders to extract the Q population. A total of 314 Q population was formed added with 251 questions extracted from related documents. Final 32 Q samples were selected by reorganization of 314 Q population after reexamining statements through inquiry of 1 professor of the nurse department, 2 students in course of nurse science masters degree and 2 students in course of doctoral degree. The P sample selection standard of this study were 25 nurses and 30 head nurses. Examination subjects themselves filled out 32 statements classified in a measure of 9 points from agreeable items to disagreeable items. Principal component factors were analyzed using the QUANL pc program after grading the contents of the P sample. Nurses recognizing subjective structure for leader behaviors of nurse manager were analyzed to be 3 factors: vision presentation type, self-capability consideration type, relationship consideration type, and head nurses recognizing subjective structure were analyzed to be 2 types: task pursuit leader type, and concord pursuit type. Nursing manager's leader behavior, expected by staff nurse are more complex and higher level which may combined with task pursuit leader type in concord pursuit leader of head nurse. Also according to Horsey and Blanchard theory(1977), the effectiveness of leadership becomes to be larger as the accordance rate between the behaviors of nurse leaders and followers reaction increase Two suggestions have been made based on the conclusion. 1. Studies on creating strategies in relation to development, management, selection of nurse leaders should be made based on this study. 2. There is a need for relative study of production and degree of similarity of leadership types based on this study.

The performance of transmission lines and its shielding design during a lightning phenomenon are quite essential in the maintenance of a reliable power supply to consumers. The leader progression model, as an advanced approach, has been recently developed to calculate the shielding failure rate (SFR) of transmission lines using geometrical data and physical behavior of upward and downward lightning leaders. However, such method is quite time consuming. In the present paper, an effective method that utilizes artificial neural networks (ANNs) to create a metamodel for calculating the SFR of a transmission line based on shielding angle and height is introduced. The results of investigations on a real case study reveal that, through proper selection of an ANN structure and good training, the ANN prediction is very close to the result of the detailed simulation, whereas the Processing time is by far lower than that of the detailed model.

This study is an attempt at developing an organizational model for collection development a n.0, pplicable to Korean university libraries at their present stage of development. An emphasis is placed on the discussion of the 'subject a n.0, pproach' as compared to 'functional a n.0, pproach' in collection development work. The case history of Pusan National University Library is extensively used. The proposed collection development model consists of the following elements : - To form a collection development team and to place under the team leader subject bibliographers as follows: Bibliographer for Serials Bibliographer for Humanities Bibliographer for Social Sciences Bibliographer for Sciences and Technologies - Collection development team could operate as a separate department or as part of other departments, i. e., Deputy Director's office, Acquisitions and Processing Department, or Resources Management Department. - Collection development team takes up the responsibility for policyrelated collection work, i. e., budget allocation, evaluation of existing collection, building core collection, preservation, weeding and cooperation. - Designated certified librarians located at the(planned) subject libraries take up the responsibility for selection. Subject bibliographers cooperate with selection librarians and coordinate their work. - Certified librarians at the Acquisitions and Processing Department are assigned subject areas. They operate as acquisitions librarian and processing librarian simultaneously with their assigned subject materials.

This research presents a prototype development and implementation of Decision Support System (DSS) for integrated river basin water management for the flood control. The DSS consists of Relational Database Management System, Hydrologic Data Monitoring System, Spatial Analysis Module, Spatial and Temporal Analysis for Rainfall Event Tool, Flood Forecasting Module, Real-Time Operation of Multi Reservoir System, and Dialog Module with Graphical User Interface and Graphic Display Systems. The developed DSS provides an automated process of alternative evaluation and selection within a flexible, fully integrated, interactive, centered relational database management system in a user-friendly computer environment. The river basin decision-maker for the flood control should expect that she or he could manage the flood events more effectively by fully grasping the hydrologic situation throughout the basin.

In this study three types of aggregation methods such as the Estimate-Talk-Consensus (ETC) process, the Estimate-Talk-Estimate (ETE) process, and as a new approach the Estimate-Talk-Leader's Estimate (ETLE) process are compared to find which one of the three group processes considered is more effective than others. We, also, investigate the effect of group size on the performance of the group processes. Some experiments were conducted. It was shown that both the ETC and the ETLE processes performed better than the ETE process in approaching correct estimates in this judgmental task. As the size group increased, only the ETC and the ETC processes were shown to result in positive effect.
