  • Si-Hwa tidal power station is using difference of the ebb and flow. The active power is dependent on up and down sea water level but if it is drastically changed because of a typhoon or waves the generator terminal voltage and active power is changed that is a chief cause of power station unstability. Therefore this paper arrange a present state of power or frequency fluctuation and generator terminal phase difference in case of occurrence a drastic change of sea water level.

  • Experience on the construction of several 100-plus-story skyscrapers including Guangzhou West Tower, Guangzhou East Tower, and Shenzhen's KK100 is described considering the increasingly strong development trend of 100-plus-story skyscrapers in China. Difficulties in the construction of 100-plus-story skyscrapers are investigated. Four innovative construction technologies receive detailed descriptions: intelligently and entirely-jacked work platforms, formwork and suspension scaffolding systems ("jacking and formwork systems"), multi-function low-carbon concrete, 5D-BIM ("five-dimensional building information modeling"), and safe and rapid vertical transport, as they have found successful applications in actual projects. Popularized systematically as technical achievements, these technologies will significantly influence the construction of similar projects in the future, and produce more social and economic benefits.

  • Chemical heat pump is a system to upgrade the low level energy such as industrial waste heat and solar energy by using coupled endothermic and exothermic chemical reactions. Dehydrogenation of 2-propanol can absorb heat near 80.deg. C and is transformed into acetone and hydrogen. Hydrogenation of acetone can liberate heat near 200.deg. C. Dehydrogenation of 2-propanol is difficult around 80.deg. C because .DELTA.G has positive value, but dehydrogenation reaction in liquid phase can overcome this problem because vaporized acetone and hydrogen can be rapidly eliminated. In this work, dehydrogenation of 2-propanol was investigated in liquid phase with Raney nickel catalyst. The energy efficiency of the chemical heat pump was estimated by computer simulation.

  • In order to keep the school's environment safe and clean, it needs to have a regular control system. There are limits to the student's abilities on keeping the school safe and clean, therefore cleaning professionals and specialized companies are needed as well. In case of financial program, principals or chief administrations are in charge of school building's environmental management. And it might cause poor efficiency and imbalance of distributing works on business in their charge and there are limits to keep the school's environment. This paper prepares alternatives of effective school building managements to solve these problems.

  • President Lee, Syngman was ROK supreme commander at the Korean war. But, it is doubt that he executed his authority and responsibility by the ROK constitution and law. At the phase of the Korean War conduct, his role may be divided into 'military operation execution one' and 'political-diplomacy one'. He appointed unqualified person to the important position of the national defence, didn't make war execution system, and was not make to meet the war. And, after transferring the ROK force operation commanding authority to the Commander in Chief, UN Command, his role was extremely trivial at the military operation execution phase. Any way, he intended to recover the inferior national strength and military capacity with USA aid, and concentrated his effort toward diplomacy with USA. At last, he succeeded in making a mutual defence treaty and gained a big result to harden Korea national security after war. In sum, president Lee was shrewd politician and diplomat than military leader. And, it can be evaluated that he supplemented the lost part of military affairs side with diplomat one.

  • The purpose of this study is to survey what strategy BACHE, a bathtub manufacturing company, chooses to implement knowledge management. Generally speaking, the success factors of this case company is follow-up management. The first factor is to use linguistic metaphors for employees to understand difficult knowledge management terms easily. The second one is that CEO tries to set and lead pro-knowledge management corporate culture. The third one is based on the CKO's competence to read business circumstances and apply the theory of knowledge management to the workplace. The fourth one has something to do with a way of knowledge creation, for example, a suggestion system and QC circle. The fifth one depends upon CKO's mission to share knowledge invented from his own company's with the rivals and large companies which order bathtubs so that overall bathtub industry can upgrade knowledge management.

  • Zohar(1980) emphasized the influence of social, organizational, and psychological context in occupational safety and health study. With this research trend, Neal, Griffin, and Hart(2000) developed a sequential safety climate model. In this paper, author examined the usability of their model the relationships among safety climates, safety knowledge, safety motivation, and safety performance(safety compliance and safety participation). The author conducted a survey to 207 manufacturing workers, and the chief results of statistical analysis are as follows : 1) the leadership has positive effects on safety knowledge and motivation, 2) the precaution activities has only positive on safety knowledge, 3) the safety system has only on safety motivation, 4) the safety knowledge and motivation have positive effects on safety compliance and participation.

  • A nurse is give much weight in the professions of hospital.The effective achievement of a goal of hospital organization needs to get nurses to contribute the structure positively through the rational personnel management of the nurses.The operation of performance rating system is necessary to improve because the nurses hold negative opinions about the resonable management of that system in most Korean hospitals.Therefore, the prupose of this research was to suggest an efficient method to solve the problem in connection with the management of nurses performance rating system.The results of the study are summarized as follows.1. As the performance rating implies the evaluation of employee's functional accomplishment and ability, and essential condition of the job was surveyed according to the job analysis of nursing activities and nurse position.That is to say, Nusrses' performances and capability is estimated in comparision with the condition of the job. 2. It is required adequacy for evaluation factors in performance rating.That is, $\circled1$ as for those who work in psychiatry or newborn baby room they should be appraied in terms of different factors from those applicable to whom work in a general staffs. $\circled2$ Evaluation factors should be concrete so that the quality and quantity of work and the potential ability of them can be correctly appraised. 3. In order to realize the object of perfamance rating system, the training on chief nurses are quite important. Also, careful practices and continuous supplementary training are required before the system is introduced.First of all, the appropriate evaluation can be mad by continuing to record the rating objects every day for the purpose of obtaining the objectivity of rating. 4. In course of transfering of the position and training, the induction of self-rating system and presentation of self-description is required to supplement functionally the performance rating system. 5. For the efficiency of nurses' performance rating system, the results of performance rating system must be reflected in promotion, allocation and training course, which makes the nurses have the motives and the organization accomplish the goal of modern nursing through its activation.

  • C4I 시스템은 군의 핵심전력이자 중추 신경계이다. C4I 시스템은 정보 그리드, 정보의 생산 분배에 사용되는 정보기반체계로 전장공간의 모든 전투요소를 정보 네트워크로 연결하여 실시간 전장정보와 인식의 공유를 가능하게 하여 과거 플랫폼중심의 전쟁개념을 네트워크 중심전 (NCW)으로 근본적인 전쟁패러다임변화를 유도하였다. 이러한 군 핵심전력인 C4I 시스템이 적의 사이버 공격대상이 될 것임이 자명함에도 불구하고 그 대비책은 거의 부재한 실정이다. 본 논문은 전 평시 사이버 공격의 핵심목표가 될 C4I 시스템 보호책 마련을 위한 보안 로드맵을 설계하였다. 본 로드맵은 C4I 시스템 보호를 위한 비전과 목표에 대한 지원 프레임워크를 제시하고 있으며, 합참 및 방사청에서 적절한 프로그램을 선정하고 투자하여 신속하고 효율적인 보안시스템 구축이 가능하도록 한다.
