This study was conducted with the aim of testing the relationship between authority-giving leadership recognized by maritime police officials with organizational citizenship behavior. There are various types of leadership. Marine police officials will be able to help solve more effective problems in practice by the authority granted due to the nature of their duties. Organizational citizenship behavior is informal, though. However, as a result, it is related to organizational development. Recently, as a study for organizational development, many studies on empowerment leadership and organizational citizenship behavior are being conducted. In this study, 168 marine police officials were surveyed. As a result of the study, the authority-granting leadership and organizational citizenship behavior of marine police officials are very important factors due to the dangers and unexpectedness of the duties of marine police officials. Policy suggestions were made for the development of the maritime police organization.

The purposes of this study were to: a) provide evidences concerning the effects of emotional leadership b) examine the impacts of emotional leadership on employee-related variables, 'job satisfaction', 'organizational commitment', 'organizational performance' and 'turnover intention', and c) identify a conceptual framework underlying emotional leadership. A survey was conducted from August 23 to November 3, 2005 to collect data from mid-level managers in food service company headquarters (N=219). Statistical analyses were completed using SPSS Win (12.0) for descriptive, reliability, factor and correlation analyses and AMOS (5.0) for confirmatory factor analysis and structural equation modeling. The main results of this study were as follows. First, the managers gave the highest point to their leaders in the emotional leadership competence 'organizational awareness : reading the currents, decision networks, and politics at the organizational level' and gave the lowest point in the emotional leadership competence 'influence: wielding effective tactics for persuasion'. Second, the means of job satisfaction was above the midpoint (3 points). Employees' job satisfaction with 'coworkers' was relatively high. However, the extents of satisfaction with 'payroll' 'promotion', and 'work environment' were relatively low. Third, the organizational commitment was above the midpoint (3 points). In the organizational commitment, 'loyalty' factor was higher than 'commitment' factor. Fourth, the means of organizational performance was above the midpoint. The highest organizational performance variable was 'internal efficiency; trying to reduce cost' and the lowest organizational performance variable was 'internal fairness ; equitable treatment and all are treated with respect with no regard to status and grade'. Fifth, most respondents intended on 'thinking of quitting ; towards turnover process'. Sixth, the test of hypothesis using structural equation modeling found that emotional leadership produced p[Isitive effects on job attitude and job performance. Emotional leadership enhanced job satisfaction and organizational commitment, and in turn, employees' attitude positive effects on organizational performance; emotional leadership also had a direct impact on organizational performance

지난 2004년 6월 24일에 공표된 신BIS 자기자본규제제도에 의거 회원국 은행들에 대한 체계적인 위험관리가 강화되는 상황에서 우리나라도 2009년부터 모든 은행이 신BIS기준을 도입및 적용할 예정이다. 신BIS협약은 운영리스크(부적절한 내부절차, 직원, 시스템)에 대해서도 리스크를 측정하여 은행의 소요 자기자본에 반영토록 하고 있다. 따라서 본 연구자는 은행의 조직환경 변수들이 조직유효성에 영향을 미치고 이들이 또한 내부통제절차의 상시 유효성에 영향을 미치는 지 알아보기 위하여 국내 소재 은행원들을 대상으로 실증분석함으로써 은행들이 효율적인 내부통제를 통해 금융사고를 미연에 방지하고 은행자산의 건전성에 기여하기 위한 지침을 제시하는 관점에서 연구를 진행하였다. 연구결과, 연구모형에서 예상한 바와 같이 조직환경이 내부통제유효성에 직접적으로 영향을 미치지만 조직몰입도나 집단응집력과 같은 조직유효성을 매개로 하여 내부통제유효성에 더욱더 영향을 미치고 있었다. 이러한 점에 비추어 본 연구의 결과를 토대로 은행내 중간관리자의 성향에 따라 개별조직 구성원들의 행동양식이나 가치관에 영향을 미칠 수 있는 현실을 감안하여 장기적인 안목에서 양질의 리더십, 조직문화 그리고 분위기 등 조직환경을 리드해 나갈 수 있도록 관리자들에 대한 교육훈련 및 소양교육을 지속적으로 펼쳐나가는 것이 중요하다고 본다.

As random access memory chip gets cheaper, it becomes affordable to realize main memory-based database systems. Consequently, reducing cache misses emerges as the most important issue in current main memory databases, in which CPU speeds have been increasing at 60% per year, compared to the memory speeds at 10% per you. In this paper, we design and implement a main-memory database system for real-time mobile GIS. Our system is composed of 5 modules： the interface manager provides the interface for PDA users； the memory data manager controls spatial and non-spatial data in main-memory using virtual memory techniques； the query manager processes spatial and non-spatial query : the index manager manages the MR-tree index for spatial data and the T-tree index for non-spatial index : the GIS server interface provides the interface with disk-based GIS. The MR-tree proposed propagates node splits upward only if one of the internal nodes on the insertion path has empty space. Thus, the internal nodes of the MR-tree are almost 100% full. Our experimental study shows that the two-dimensional MR-tree performs search up to 2.4 times faster than the ordinary R-tree. To use virtual memory techniques, the memory data manager uses page tables for spatial data, non- spatial data, T-tree and MR-tree. And, it uses indirect addressing techniques for fast reloading from disk.

Cloud services are readily available through a variety of media, attracting a lot of attention from users. However, there are various security damages that abuse the privacy of users who use cloud services, so there is not enough technology to prevent them. In this paper, we propose a protection model to safeguard user's privacy in a cloud environment so as not to illegally exploit user's privacy. The proposed model randomly manages the user's signature to strengthen the role of the middle manager and the cloud server. In the proposed model, the user's privacy information is provided illegally by the cloud server to the user through the security function and the user signature. Also, the signature of the user can be safely used by bundling the random number of the multiplication group and the one-way hash function into the hash chain to protect the user's privacy. As a result of the performance evaluation, the proposed model achieved an average improvement of data processing time of 24.5% compared to the existing model and the efficiency of the proposed model was improved by 13.7% than the existing model because the user's privacy information was group managed.

This study aims to analyze a whole network effectiveness by expanding the unit of analysis beyond individual organizations in a network into network-level collaborative relations. Data for the analysis were drawn from the evaluation reports and surveys of leaders, mid-level managers, and staff members of the organizations participating in 'Community Network Building' project which was funded by Community Chest of Korea and carried out by the Academy of Korean Social Welfare Administration from November 2006 to November 2009. For the analysis, three out of the 10 networks established in diverse local communities were selected. Based on the survey conducted on the participating organizations and the center organization of each network, we analyzed the structural characteristics of interorganizational network at a network-level. Second, to analyze effectiveness of the whole network, we employed a multiple stakeholders perspective and examined the relations between the whole network's structure and its effectiveness. The findings showed that the whole network effectiveness is higher when the network is more centralized around the hub organization and more stable. The significance of this study is that it is provided and tested a new framework for network effectiveness evaluation by combining the two network effectiveness evaluation framework of Provan and Milward's with evolutionary organizational theory.

This is a case study with the objectives of performing an in-depth investigation of the development process, outcome, and the factors related to the development process of Jinggomdari-the self-help group for divorced single parents at Wolgye social welfare center. Document review, in-depth interviews of the member/practitioner/middle manager, and participatory observations were performed and qualitatively analyzed. The results showed that the development process of Jinggomdari consisted of 4 phases including initiation, formation of basis, growth, and expansion/independence. Two categories including 'nurturing abilities and growth as an individual or within families or communities' and 'beyond Jinggomdari, into society', 6 subcategories, and 31 concepts were derived as the outcome. In terms of the factors related to the development process and outcome, 6 categories including 'members participating with sympathy despite various issues', 'outstanding and stabilized leadership', 'commitment of the practitioners showing utmost efforts despite shortcomings', 'effective functions as the hub supporting the low-income divorced single parents families based on the institution's firm determination', 'mixed group showing cautious but synergistic effects', 'dilemma of managing the low-income divorced single parents self-help group and lack of manual for management', 20 subcategories, and 61 concepts were derived. Management issues concerning low-income divorced single parents' self-help group was discussed based on these results.

This article aims to understand the process of effective leadership in the Community Care Centers for the Disabled(CCCD). Using a qualitative approach and the concept of 'Sensemaking', a term introduced by Weick (1995), I described and explored the process of leadership. Sensemaking enables leaders to have a better grasp of what is going on in their environments. Sensemaking theory offers a perspective on leadership that resolves successfully complex situations surrounding the CCCD. The CCCDs face the environmental changes such as a paradigm shift of disability and a rivalry system with private services. In this time of uncertain change, the CCCDs are in need of leadership of the executives who could reduce complexity with shared meaning. Data were collected over 5 weeks from the 6 CCCDs, through semi-structured interviews, with practitioners, middle managers and chief executives. The interview scripts were thematically analyzed through Atlas-ti programme. The findings showed three subjects, the people's perception of environment, organizational visioning and interactions among post positions. Even though the 6 CCCDs were under the same environment, the perceptions and the enactments of the practitioners were influenced by the chief executives' sensemaking. The important factors of the chief executives' sensemaking were the daily interaction as well as ongoing reflection on their experiences.

In this study, we reviewed the main strategies and contents of the work style innovation promoted by the Moon Jae-in government, and analyzed the contents and success factors of the work innovation based on the case of a specific local government. In particular, this study analyzes the case of innovation in the way of working through simplification of work, and the local governments, which were the subject of the study, received excellent evaluation in the government innovation evaluation of the Ministry of Public Administration and Security in 2019. In this study, we conducted in-depth interviews with employees of local governments to examine the problems, achievements, and success factors related to business simplification. First, it was found that it is very important to form consensus so that the members of the organization can participate in the change in order to simplify the task. Second, incentives, such as HR, were needed to induce active participation of members in the innovation project called Simplification of Work. Third, in order to induce and support organizational change, it was found that the interest and support of middle managers and directors were the most important factors. The results of this study will help to prepare the policy for innovation in the public sector's working style.
