This essay was written with the purpose of finding an effective outline of reorganizing the theoretical establishments of institutional household management. We have proposed a few alternative models for the reorganization of the theoretical system of institutional household management after analyzing the theoretical systems of Management and Administration: First, institutional household management should embrace the concepts of positive management. Second, we should organize a plan where such factors as organization system, human resource development, advertisement and consumer satisfaction surveys could be introduced and strengthened within the theoretical system of institutional household management.

Recently people show interest in cultural exhibition space targeting on children from the birth of children to play and education. Accordingly, lately the necessity of professional special exhibition space, which is composed of changeable program fit to the children trend of a growth period, and shows relatively more freedom and adaptability in directing the theme than permanent exhibition, have increased rapidly. Today the social importance of special exhibition for children is emphasized as an alternative that can provide efficiently the expression of freedom and the environment of experimental space which is not filled in existing academy or school. The necessity of special exhibition space for children is raising to the climax at this moment, this study has the meaning to analyze the direction of domestic special exhibition for children progressed in last 1 year, and then to suggest basic guide and direction for future plan of special exhibitions.

Epoxy/mica has been used as the material of high-voltage rotator stator winding due to its high insulation performance, mechanical strength, and thermal stability. In recent years, however, it shows frequent changes in the load of generators and frequent automatic stops due to the significant increase in peak loads from the increase in the applied load of power facilities according to the introduction of advanced and high-technology equipments. Thus, it is necessary to develop new materials that highly develop the conventional insulation materials. Nanotechnology introduced in the present time has become an alternative plan that overcomes such technical limitations. In addition, the nano-scaled intercalation composite has been known as the material that represent excellent electrical, mechanical, and thermal characteristics compared to the conventional materials. This study investigated the dielectric dispersion and relaxation characteristics of the nanocomposite, which was fabricated by mixing epoxy matrix with nano-scaled intercalation mica and clay, according to changes in frequencies and temperatures.

동기방식 System에서는 모든 하위 Block에서 동일한 시간정보를 유지하는 것이 중요하다. 대부분의 기능들이 기준 Clock에 동기된 시간정보를 가지고 구현되므로 시간정보가 틀려지면 System에 치명적인 영향이 미치게 된다. 그러므로, 중요 Block에서는 이러한 시간정보/clock Signal의 정상 수신여부를 점검하는 부분이 꼭 필요하다. 본 논문에서는 Clock Signal을 점검하는 방법을 살펴보면서 발생할 수 있는 문제점에 대해 논하고 대안을 제시하고자 한다.

We report the treatment of an adult Class II malocclusion with severe crowding and a hopeless lower second molar. According to the treatment plan, 4 premolars and 4 third molars were to be extracted for 2-jaw surgery. To replace the hopeless lower second molar, one upper third molar was successfully autotransplanted during the pre-surgical orthodontic treatment. Multiple teeth are frequently extracted for treatment purposes in adult surgical cases. Under precise diagnosis, the reuse of extracted teeth to replace missing teeth can be a successful alternative even in adult surgical patients.

Internal engine is the main power source of vehicle and is the main source of air pollution. To satisfy this getting rigorous emission regulation, it must be solved simultaneously the dilemma of reducing emission gas and increasing heat efficiency. Diesel engine is preferred compare with gasoline engine in aspect of energy consumption but it must be solved reducing the containing of NOx, CO and HC. In this study: 1. Looking for alternative of performance improvement of Exhaust Gas Recirculation(EGR) which is emission gas reduction system. 2. Reducing malfunction of controlling emission gas. 3. Made possible precision control.

도로의 노선 선정은 기본적이면서도 중요한 과정이다. 하지만 노선 선정 과정은 기술적, 교통적, 환경적 요인 등을 동시에 고려해야 한다. 여러 대안노선을 검토하여 이용가치를 극대화하고 공사비를 절감할 수 있는 최적노선을 선정해야 한다. 본 연구는 도로건설공사의 기본설계단계에서 GIS와 연계될 수 있는 방법들을 분류하고 주관적 평가를 통해 합리적인 노선 선정 방안을 제시하고자 하였다.

With increase of load power the case it will not be able to supply the power which is necessary to the vehicle, it establishes dosage increase of main transformer of substation or power compensation equipment, and must supply the power which is necessary. But like this method the expense and the hour when it is considerable are necessary. As an alternative plan, if neighborhood substation can supply power through parallel feeding then it can supply power applying the equipment of existing. So we investigate the possibility of parallel feeding method between neighboring substations through measuring results of voltage phase difference and analysing feeding circuit,

According to the need for objectivity and convenience the whole planning process is devided into a secries of 8 systematic stages. But it is an unending upward spiral of incremented efforts toward improvement. So many activities should be carried out concurrently, providing a mutual supportive flow back and forth between various stages of the process depending on local conditions and requirements. The eight stages are: (1) Planning the Planning and Developing Planning Competence (2) Statements of Policy and Broad Goals (3) Data Gathering (4) Priority Statement (5) Statement of Major Alternative Proposals (6) Development of Detailed Plan (7) Implementation as a Part of the Planning Process (8) Evaluation The frame and function of the planning machinery must be adjusted to local conditions, and also flexibility is desirable, especially at the start, when adaptations are more necessary and more frequent.

A commodity distribution problem with intertemporal storage facilities and dynamic transportation networks is proposed. mathematical integer programming methods and multiobjective programming techniques are used in the model formulation. Dynamic characteristics of commodity distribution problems are taken into account in the model formulation. storage facility location problems and transportation link addition problems are incorporated into the intertemporal multicommodity distribution problem. The model is capable of generating the most efficient and rational commodity distribution system. Therefore it can be utilized to provided the most effective investment plan for the transportation infrastructure development as well as to evaluate the existing commodity distribution system. The model determines simultaneously the most efficient locations, sizes, and activity levels of storage facilities as well as new highway links. It is extended to multiobjective planning situations for the purpose of generating alternative investment plans in accordance to planning situations. sine the investment in transportation network improvement yields w\several external benefits for a regional economy, the induced benefit maximization objective is incorporated into the cost minimization objective. The multiobjective model generates explicitly the trade-off between cost savings and induced benefits of the investment in transportation network improvement.
