본 논문에서는 고객의 다양한 감성에 기반한 웹 디자인을 통해 사용자들로 하여금 새로운 경험을 체험하도록 정적과 동적 요소에 따른 16개의 감성 차원을 모델링하고 페이지 레이아웃, 배경색, 움직임 좌표 등의 감성 데이터베이스를 활용하여 고객의 선호 감성에 따라서 웹 페이지가 재구성되는 유무선 인터넷 서비스 시스템을 제안한다. 실험 결과 기존 시스템보다 세대별 감성 만족도 및 웹 사이트의 평균체류시간이 증가되었음을 모의 실험을 통해서 확인하였다.

Phase spearated glass is heterogeneous in microscopic point of view and the heterogeneities affect the structures of glasses. In the present work the phase separation of $BaO-B_2O_3$ glass system was investigated and the effect of $P_2O_5$ on the phase separation and crystallization was also studied in the above system. Experiments such as scanning electron microscopy X-ray diffraction and infrared spectroscopy were performed. Phase separation with $B_2O_3$ rich phase matrix and BaO rich phase droplet was observed for the glasses containing less than 6 mole% of BaO while the opposite morphology of phase separation was found for the glasses containing more than 7 mole% of BaO. Phase separation region was extended up to the glass with 22mole% of BaO when the amount of $P_2O_5$ was increased. The heat-treated glasses crystallized to BaO.$4B_2O_3$$P_2O_5$ hindered the glass from the crystalli-zation.

This work describes identification of essential considerations when we develop OMS/MP for the shipboard weapon systems. It is compulsory to develop OMS/MP which describes quantity of what mode to have and how often to operate. In this point of view, relationships between OMS/MP and shipboard weapon systems are analyzed. From the analysis, considerations of OMS/MP development for the weapon systems are presented.

Recently, with the increasing of construction works, large construction equipment are used to reduce the term of work and labor cost in construction field. Therefore, construction equipment noise has caused much annoyance for a number of dweller in nearby construction field and it has become a very serious problem in our living environment. Neverthless, in our country, adequite guidelines for the construction equipment noise are very deficiency because of the lack of basic data and insufficient research works. From this point of view, this study attempts to survey the characteristics and prediction of piling noise in oil pressure method. On the basis of measurement value, we analysed about prediction possibility of piling noise in oil pressure method.

This study is to propose directions of waterfront planning about fishing village and harbor in East coast. Above all important waterfront-using in harbor, such as regional atmosphere and sea-scape are to investigate waterfront elements. For example, seaside park, harbor street mall, landmark, view point, promenade can be checked and design of waterfront may be possible to work out future harbor master plan. This study suggests that harbor of contemporary is to develop by regional waterfront characters. Accordingly, we analyze, it shows that the waterfront planning not only people of village but also visiting citizen is one of the important in developments about fishing village and harbor. As a results of this paper, we expect this research to be used as a valuable data in waterfront planning about fishing village and harbor.

There are two kind of method to perform a safety management in industrial field. One is a management by safety manager employed in company and another one is safety management by acting agency. In case of the company that managed by the acting agency dose not coincide with the state of company and safety management performance because of the safety management is carry out by periodically. Therefore it is considered that the sufficient safety management is difficult. And a company that employ a safety manager also show a low level of safety management compare with the advanced country in view of safety and health. From the statistics of accident rate of the company, it is necessary that an improved safety management through the studying and analysing a coverall matters for the company that managed by acting company.

This paper presents an advanced control technique for power density maximization of the Brushless DC (BLDC) generator by using the linear tracking method. In a generator of given rating, the weight and size of the system affect the fuel consumption directly. Therefore, power density is one of the most important issues in a stand-alone generator. BLDC generator has high power density in the machine point of view and additional increases of power density by control means can be expected. Conventional rectification methods cannot achieve the maximum power possible because of hon-optimal current waveforms. The optimal current waveform to maximize power density and minimize machine size and weight in a nonsinusoidal power supply system has been derived, incorporated in a control system, and verified by simulation and experimental work. A new simple algebraic method has been proposed to accomplish the proposed control without an FFT which is time consuming and complicated.

This research proposed the Direct Construction System for construction corporations as a strategy intended to perform cause analysis of construction technician shortage matter and solve resulting problems, and in view of the outcomes from the application of this system to the projects and workshops, it was verified that unsteady employment, lack of career prospect, and conditions of work environment can be resolved. In addition, from corporations' perspective, it is considered that by clarifying the abovementioned three problems, fundamental complications of construction administration, quality control, safety supervision, and cost management were settled, concluding forthcoming advancement of domestic construction business quality fell far behind developed counties.

There are real life situations in our lives where the things are changing continuously or from time to time. It is a very important problem for one whether to continue the existing relationship or to form a new one after some occasions. That is, people, companies, cities, countries, etc. may change their opinion or position rapidly. In this work, we think of the problem of changing relationships from a mathematical point of view and think of an answer. In some sense, we comment these changes as power changes. Our number theoretical model will be based on this idea. Using the convolution sum of the restricted divisor function E, we obtain the answer to this problem.

This paper's objective is to provide insights about the problems and expansion strategies of electronic trade. Korean small and medium-sized firms have adopted the Internet since the end of 1990s in order to reshape their competitiveness, and it is now being utilized as a major export marketing instrument to develop new customers, save export transaction costs ad facilitate new work processes. However, at present, the use of the internet in the field of trading is limited to the collection of market information, owing to legal, technical and institutional restraints between countries. In addition to that, because firms have the difficulties in making the trade contract through the e-trade system, the negative recognition on its' utility has been spreaded gradually between companies. This is one of the barriers to block the expansion of e-Trade between Korean firms. Therefore, this paper points out the problems of e-trade in the environmental, institutional and strategic view and provides many considerations for establishing the expansion strategy of e-trade by the Korean government and trade supporting institutions.
