우리 나라 중소기업의 지식영영 수준을 비교 평가하기 위하여 150개 업체를 대상으로 설문 조사 하였다. 연구 모형은 1) 지식경영과 기업전략 2) 지식경영 문화와 체계 3) 지식경영을 위한 학습 과정과 공유 4) 지식경영을 위한 정보기술 5) 지식경영 성과측정과 보상에 대하여 평가하였다. 연구 결과로는 기업의 특성에 따라 지식경영 수준 차이가 있다는 것이다. 특히, 우리 나라 기업에서 지식경영을 위한 기업 문화 형성이 미흡하며, 지식경영을 위한 학습과정과 성과과정 및 보상이 다른 영역에 비해 상대적으로 낮게 나타났다. 우리 나라 기업의 특성을 맞는 지식경영의 평가 개발이 요구된다.

채널은 무선망에 있어서 한정된 주요 자원 중의 하나이다. 다양한 채널 관리 기법들이 제시되어 왔으며, 최근 들어 가드채널의 최적화 문제가 부각되고 있다. 본 논문에서는 신경망을 이용한 지능적인 채널 관리 기법을 제안한다. 신경망의 학습 데이터 생성과 성능분석을 위하여 SRN(Stochastic Reward Net) 채널 할당 모델이 개발된다. 제안된 기법에서 신경망은 지도학습 방법인 역전파 알고리즘을 이용하여 최적의 가드채널 값 g를 계산하도록 학습한다. 학습된 신경망을 이용하여 최적의 g를 계산하고, 이를 SRM모델에서 구해진 결과와 비교한다. 실험 결과는 신경망에서 구한 가드채널 수와 SRM모델로부터 구한 가드채널 수의 상대적 차이가 없음을 보여준다.

The optimal price strategy selection of two bounded rational cognitive mobile virtual network operators (MVNOs) in a duopoly spectrum sharing market is investigated. The bounded rational operators dynamically compete to sell the leased spectrum to secondary users in order to maximize their profits. Meanwhile, the secondary users' heterogeneous preferences to rate and price are taken into consideration. The evolutionary game theory (EGT) is employed to model the dynamic price strategy selection of the MVNOs taking into account the response of the secondary users. The behavior dynamics and the evolutionary stable strategy (ESS) of the operators are derived via replicated dynamics. Furthermore, a reward and punishment mechanism is developed to optimize the performance of the operators. Numerical results show that the proposed evolutionary algorithm is convergent to the ESS, and the incentive mechanism increases the profits of the operators. It may provide some insight about the optimal price strategy selection for MVNOs in the next generation cognitive wireless networks.

The purpose of this research was to understand the structure of the experiences of turnover among hospital nurses. The research question was 'What is the structure of the experiences of turnover among hospital nurses?' The sample consisted of 16 hospital nurses who experienced one or more turnover. The unstructured interview were carried out from July 15. through August 31., 1997. Intervewed by audio-recording and analyzed by Van Kaam's method. There were 361 descriptive expressions and priority classifications. The result summerized as 107 common elements, 38 syntheses of hypothetical definitions and 6 identifications of the structural definition. The structural definitions and hypothetical definitiones were as follows ; 1. There were different views on the turnover intention. Hard task, dissatisfaction of initial expectancy, uncomfortable relationship with doctors, inappriate reward, uncomfortable relationship with workers of other parts, uncomfortable relationship with patients, unreasonable promotion, uncomfortable relationship with co-worker, helplessness, poor environment of working conditions. 2. Motivating factor of turnover can be varied : self development, problem of social support, boring task, problem of relation-ship with the senior, unfair promotion, night duty. 3. Social supportive factors were co-worker support, senior support, self control, family support, time support. 4. There were different views on the job satisfaction. Task, relationship with patient, recognition, professionalism, promotion, working environment, relationship with co-worker, reward.

The purpose of this study was to verify the influences among job stress, stress-coping style and job satisfaction of the elementary school teachers. An objective of study is 256 elementary school teachers. After choosing 7 schools located in Busan, 283 teachers participated in this study. The measurements used in this study were the teachers' job stress scale, coping ability scale against stress, and the Korea Teacher Opinionnaire Test. The collected data were analyzed with SPSS 14.0 program. For handling data, correlations and Multiple Regression Analysis was conducted. Major findings were summarized as follows: First, it is found that reward & personnel management in sub-variables of job stress and control method in sub-variables of stress-coping style has significantly predicted job satisfaction level. Second, in sub-variables of job satisfaction, reward & personnel management, control method, management system, learning establishments has significantly predicted duties, increase of specialty, human relationships, and work atmosphere, respectively. Finally, the limitation of this study and suggestion for further research are presented.

The present study investigated fashion Instagram marketing, applying the concept of gamification. It set out to examine the following specific issues: 1) perceptions of flow, pleasures, dimensions of game dynamics (challenge, competition, achievement, reward, relationships among participants, and relationships between brands and consumers), and consumer responses based on frequency and involvement in exercise; 2) the effects of game dynamics dimensions on flow and pleasure; and 3) the effects of flow and pleasure on consumer responses. An online survey was used to gather data and the study analyzed a total of 200 responses. The results of the study were as follows. Perception differences were found only in relation to exercise involvement. Competition, relationships among participants, and relationships between brands and customers positively predicted flow. Among the dimensions of game dynamics, challenge, competition, reward, relationships among participants, and relationships between brands and consumers positively influenced pleasure. In addition, the study also found that pleasure and flow had positive effects on intention to participate and brand loyalty. Meanwhile, only pleasure predicted word-of-mouth. These findings suggest that fashion brands implementing Instagram as a marketing channel should seek to stimulate pleasure and fun to provoke positive consumer responses. Furthermore, the findings of the study provide practical and useful insights for fashion brands implementing Instagram marketing.

As the importance of Knowledge Management System (KMS) in the military increases, Republic of Korea Army (ROK Army) developed Army Knowledge Portal. Although the members in the military are encouraged to use the portal, few members currently use it. This study was conducted to find variables to predict the user's intention to use the portal, which contributes to activating the use of Army Knowledge Portal in the army. On the basis of Technology Acceptance Model (TAM), ten variables such as perceived ease of use, general information security awareness, information security awareness, expectation for external rewards, expectation for relationships, sense of self-worth, attitude toward compliance with security policy, attitude toward knowledge sharing, intention of non-combat knowledge sharing, and intention of combat knowledge sharing were considered as independent variables. 105 participants on active duty who currently use or have experience to use the portal participated in this study. The results indicated that general information security awareness and information security awareness increases compliance with the information security policy. In addition, the attitude toward knowledge sharing is enhanced by expectations for relationship and sense of self-worth. Based on the results, the authors propose the need for policy alternatives to reinforce the reward system and security policy, which activates the use of Knowledge Portal Service for ROK Army.
