This study was performed to compare the foodservice management practices in the employee feeding operations of Jeonnam and Chungchong area. Questionnaires were developed and mailed to 160 dietitians with management in employee foodservice of Jeonnam and Chungchong area. Completed questionnaires were received from 124 dietitians with a response rate of 77.5%. The results of this study can be summarized as follows:. Age, work experience, concurrent position and work time of dietitians were significantly higher in the Chungchong area than those in the Jeonnam area. Times of meals and amount of meals served per day in the Chungchong area were significantly higher than those in the Jeonnam area. The type of menu by foodservice operation was high non-selective menu in both areas, especially non-selective menu was high in self-operated place whereas selective menu was high in contract management. Period of cycle menu was 10-15 days in Jeonnam area, but that was 7 days in Chungchong area and so cycle menu of both areas was significantly different (p ＜ 0.001). Most considerable factor in menu planning was preference in Jeonnam area and was cost in the Chungchong area. Food purchasing method was used mostly by automatic computerized order in the Jeonnam area whereas telephone or mail order was high in the Chungchong area.

It has been increased the importance of computer education for the knowledge information society. However day by day. But computer education is currently operated with elective subjects in discretion action scope in a middle school. These operation of elective subjects brings a tended to neglect computer course, and inappropriate class number operated from this operation deteriorates reality and efficacy of computer education. Therefore, this paper compared and analyzed various operation methods of elective subjects that have been currently operated and grasped various problems to appear according to operation methods. When computer subject is operated using results from analyzing these problems, we find the most suitable way and provide sufficient references to operate computer subject in school education.

The form or interpretation of today's communication design lies in content development and storytelling to the designer. However, the understanding as well as exteriment of the mechanisms behind content creation remain an obscure concept. Particularly given the rapid development of digital technology, since the 1980s typography has been quickly transforming itself from its static state to the more dynamic'Type in Motion'. following this came the need for solid research in'Type in Motion'as the best means of presenting story content and form The previous passage has studied the effectiveness of'Type in Motion'in presenting this kind of content. Type in Motion has allowed vast developments in the methods of story presentation. It is Due that today's digital technology has given many benefits to the designer, but on the other hand, it has required a more diverse understanding of digital design. furthermore, even the designers in digital typography lack the understanding and research in'Type in Motion'not only as a mode of visual language but also of verbal language. Given this point· in hand, the entire interpretation and interrelation of story and'Type in Motion'can be considered essential, given their shaping of effective digital typography.

This study examined in detail how the store characteristics and store owner characteristics of nadle store affect the management performance. First, as a result of analyzing the sales results according to the business experience and the same residency, the non-resident of the workplace was 842,000 won, which was 92,000 won higher than the residence. Among the store owner with experience, non-residents were the highest with 918,000 won. Second, as a result of analyzing the sales performance according to the operation type and the store size, the highest sales type was the mart type, followed by the inclusion of fruits and vegetables with an average of 874,000 won. When looking at the size of stores, more than 60㎡ was 790,000 won. The highest operating type of sales over 60㎡ was mart type, which was 960,000 won, followed by convenience stores with an average of 933,000 won. These results will serve as a reference for suggesting not only the small business policy of the government but also the management efficiency of retail stores.

In the study, we estimate efficiencies using CCR model of DEA, Super efficiency(AP) model, and super-SBM model with the data of 32 regional public hospitals in Korea from 205 to 2009. With Wilcoxon-Mann-Whitney statistics, we analyze efficiency differences for environmental factors(regions, type of hospital, type of operations, type of education training, relative importance of madicaids) among regional public hospitals. The results can be summarized as follows. Firstly, technical inefficiencies of regional public hospitals range from 15% to 17% in CCR model, 13% to 15% in AP model, 7% to 12.6% in SuperSBM model. Second, we confirm that environmental factors of hospitals cause different inefficiencies among them. The implication of this study is that policy and institutional change may need to improve the efficiencies along with internal managerial reform.

This study was performed to analyze the operation system of transfer crone to improve the reality of yard operation roles in container terminal and present the applicable method of operation rules to apply the operation priority. And we derived the procedure to estimate the maximum number of waiting truck based on the waiting of truck and the occupancy of driving lane in yard, and analyzed the constraint state of space. To solve the space constraint, we provided a multi-job principle to define the space resource and described the solution and sequence diagram for the principle.

미래의 전력 시스템은 환경과 기술적인 이유로 인해 더욱더 많은 분산전원을 이용하게 될 것이다. 분산전원은 서로 다른 특징을 가지고 있고 또한 배전계통에서 기존의 계통운영과는 다른 형태로 운전될 것이다. 이런 관점에서 다수의 분산전원을 모아 하나의 가상의 발전소로 운영하는 개념이 등장하게 되었는데, 이를 Virtual Power Plant(VPP)라고 한다. VPP는 매니지먼트 시스템이 관리하는 여러 클러스터들로 이루어져 있으며 이들 클러스터들은 각각 여러 종류의 분산전원으로 구성되어 있다. 본 논문에서는 클러스터를 이루는 분산전원을 어떻게 운영하는 것이 최적의 경제적 효율을 지닐 수 있을 지에 대해 논의하게 될 것이다. 디젤 발전기의 출력의 경우 그 소유자에 의해 제어가 가능하지만, 태양광 발전 시스템의 경우 기상 상태에 따라 그 출력이 결정된다. 따라서 이러한 각각의 특성을 고려하여 본 논문에서는 디젤, CHP(Combined Heat and Power), 보일러, 태양광발전으로 구성된 복합 시스템에서 각 시간별로 수용가의 전력 및 열 수요와 분산전원의 에너지 생산을 비교하여 VPP 최적 운영 계획을 구성하였다.

본 연구에서는 21세기 주된 화두의 하나인 테크노경영을 통한 국방자원 운영혁신 전략을 제시한다. 테크노경영이란 기존의 경영개념에 첨단 기술 지식을 접목시켜 새로운 형태로 발전된 최신 학문분야이다. 이러한 테크노경영이 주목받는 이유는 21세기의 강대국 개념이 군사력과 경제력이 아닌 기술력에 크게 의존할 것으로 예상되기 때문이다. 따라서 국가와 기업의 경영에 이제는 정보기술이 반드시 접목되어야 한다는 추세에 부응하여 본 연구에서는 정보기술(IT)에 기초한 테크노경영을 이용한 국방자원 운영혁신 방안을 군의 핵심자원 요소인 인력자원, 군수자원, 지식자원으로 구분하여 제시하였다. 본 연구를 통하여 날로 첨단화 되어가고 있는 무기체계 및 국방정보전력체계를 보다 효율적으로 운영하는데 실질적으로 기여할 수 있을 것이다.

하드웨어와 응용 프로그램의 다양한 요구를 만족시키기 위한 운영체제의 재구성 능력이나 기능 확장에 대한 필요성은 최근 들어 급증하고 있다. 운영체제의 재구성을 지원하기 위해서 개선되어야 할 부분 가운데 가장 정적이라고 할 수 있는 부분은 인터럽트 처리와 같은 저수준 입출력 부분이다. 이러한 인터럽트 처리는 하드웨어와 밀접한 부분으로써 운영체제의 설계목적에 따라서 설러 가지 방식으로 구성되어왔으나 각 운영체제에 의존적이며 처리방식이 고정적이라는 한계를 가진다. 본 논문에서는 다양한 형태의 인터럽트 처리 방식을 지원할 수 있는 동적 재구성이 가능한 인터럽트 처리 방식과 그 구조를 제안한다. 제안하는 방식은 커널 컴포넌트들의 동적인 확장과 재구성을 지원하는 커널 컴포넌트 스와핑과 인터포지션 기법을 사용하여 M3K 커널에 구현되었다.
