  • 우주 발사체에 사용되는 엄빌리칼 시스템은 지상의 유공압 및 전계장 라인들을 발사체로 연결하여 발사운용 과정에서 발사체 내부로 유공압의 공급 및 발사체와 전기적 연결들을 가능하도록 하다가 발사직전 또는 발사와 동시에 발사체로부터 분리되는 장치이다. 발사운용과정에서는 전기적 및 유공압적으로 확실히 연결되어 기밀 및 체결 성능을 보장하여야 하고 분리시점에는 확실한 분리특성을 보장하여야 한다. 따라서 체결력을 적절하게 선택하여 체결력과 분리성능 두가지를 모두 만족시키도록 하는 것이 엄빌리칼 시스템 설계의 핵심 요소이다. 이와 같은 장치 특성에 따라 엄빌리칼 시스템은 우주발사체 개발 초기부터 현재까지 다양한 형식의 엄빌리칼 장치들이 연구되고 발사체에 적용되어 왔다. 본 논문에서는 현재까지 주로 사용되었던 각 엄빌리칼 시스템들 그 특징과 그 작동개념별로 구분하여 기술하고 향후 한국형 발사체에 적용될 엄빌리칼 시스템의 개요에 대해 소개한다

  • This study aims to explore how teachers construct scientific explanation during instructional practices to help students' scientific inquiry. Before investigating teachers' classroom practices, elementary school science curriculum was examined to identify scientific concepts, particularly in earth science. Then, a total of six teachers' scientific explanation in actual teaching practices was analysed focusing on a) explanation of scientific concepts; b) rationale for scientific explanation; c) connection between scientific explanation and everyday explanation. The findings are as follows. First, the science curriculum provides $1{\sim}2$ main scientific concepts per unit, which are mostly appeared in the unit title. Those concepts and sub-concepts are not explicitly described but embedded in students' inquiry activities. Second, the teachers explain scientific concepts and discuss the rationale behind the scientific explanation, but rarely connect scientific explanation to everyday explanation. Also, the level of scientific explanations is low remaining level 1 or 2, not reaching 3, the highest level. Based on the results, the study suggests a) teachers need to provide explicit and clear explanations about scientific concepts; b) teachers are required to connect scientific explanation and everyday explanation; c) the level of teachers scientific explanation should be elevated by using an evidence, reasoning and claim, the components of scientific explanation as well as introducing new scientific concepts and inquiry activities.

  • It is a remarkable phenomenon that tattoos has been rapidly spreading among women of modern years. The extremism of feminine ornaments, and pricking and piercing of the skin seem to have deep connection with women's consciousness changing to being independent, active and aggressive. The objective of this study is to analyze the potential quality of today's women, who appears emblematically through tattoo, and to search out the whole aspect and keynote of female tattoos. The methods of research are by examining the general characteristics including concept and history, considering the type and significance of ethnic female tattoos, and then comparing with the symbolism of today's female tattoos. The sphere is limited to women's tattoos from ancient times to today's modern lift, examined from large portions of Africa, Asia, Australasia, the Americas, and Arctic regions. As a result, the following had been reflected in female tattoos in the past. First, incantation, tribe, adult age, adornment, marital status, domestic ability and sex distinction, where among others, the incantatory, ornamental symbol, and domestic sign were representatives. Second, the most popular body parts for having a tattoo were around the lips, hands and abdominal region. Third, the more harsh the environment becomes such as tropical forests, isolated islands, and polar regions, the more number of females have tatoos. Fourth, women's tattoos were much less glamorous and smaller compared to those of men, distinguishing one's sex. On the other hand, today's female tattoos can be classified as five symbols: masculinity, independence, voluptuousness, affection, and purity. These symbols contain women's mentality to pass the limit, and to overcome social inferiority. In modern society, where women must compete with met it has become necessary for women to educe their potential masculine qualities. Being violent accessories for them, tattoos became a mark of such potential. Therefore, in the future, women's interest and demand for tattoos are expected to rise in proportion to the social demand of women's force.

  • Following conclusions about Taeyang meridian and Taeyang type were obtained through studies with reference to the books of ${\ll}$Donguibogam${\gg}$, ${\ll}$Hwangjaenaegyung${\gg}$, and ${\ll}$Special Lectures of Master Jisan on Medical cases${\gg}$ . Park noticed that there was difference in the development of 12 meridians among the individuals and tried to apply it in the diagnosis and the treatment of the disease, thereby creating the theory of the six meridian types. The literal basis is assumed to a phrase in ${\ll}$YoungChu GyungMaek${\gg}$ , ‘人經不同 絡脈異所別也’. Taeyang meridian runs through the back of the human body. The concept of TaeYang includes surface, starting point, diffusion of Yang Gi, and emission. Small intestine meridian of hand Taeyang manages the liquid and Bladder meridian of foot Taeyang manages the muscle. There is much flow of blood and less of Gi in Taeyang meridian which makes the connection to hair, flesh, liquid, muscle and vessel. Taeyang conceals and condenses objects because it belongs to Hansu according to division of Six atmospheric influences and to the winter. The articulation is stiff and urination and elimination are abnormal when disease occurs in this meridian. The pathology of Taeyang meridian would be the invasion of outer filthy Gi affecting the Bladder meridian of foot Taeyang which then again makes Kidney meridian of foot Soeum sick. The two meridians compose the outer part and the inner part of th body. The bladder itself becomes sick sometimes. The condition of less Gi in Taeyang meridian can easily result in the shortage of Gi, and much blood makes the person to have a lofty ideal or to have capricious behavior.

  • If human beings could make friends with nature, it would be a truly wellbeing. This project has selected the design concept under the supposition that human beings and the nature become friends. This residential house, which is consisted of one ground floor and two underground floors, is confronting the mountains that surround the residential complex. Residents can enjoy viewing the mountains from the living room. The garden is created by using this given environment in maximum. The walls are made up with rocks, and a small pond is formed with water from the mountain, presenting another attractive sight. Through the connection rather than the break between mountain and garden, living room and garden, and again garden and mountain, the dialogue with nature was attempted. The water of the pond in the garden flows down along the walls and creates another water space at the gate area of the house. Passing through the entrance, there are a living room, a kitchen, a bedroom for spouses, a common bathroom, and a library on the ground floor. On the second floor, there are two rooms, a bathroom, and a mini living room. The platform of living room on the 1st floor is lowered to produce the comfortable living room with the hearth. From the view of living room, the garden with full feeling of nature can give a good emotional rest for modem people who want the mental relaxation. The marble stones are used as its material to present rich texture and sophisticated image presentation. The hearth in the living room is harmonized with high-tech electronic home appliances and surrounding accessories. On the kitchen, the high-glossy materials are used to express the external appearance neatly and the depository function is more improved for housewives.

  • Recently, the number of 'field-museums(F.Ms.)' in Japan has increased. Although they are very diverse, the essential commonality is that each has a field arranged as a kind of museum. In this study, we examine the 'F.M.' mainly through documents in order to understand the concept of the F.M. and the direction of further studies. Before examining the cases of F.Ms., we explore the history of the F.M. and the role of museums in order to establish the background of the development of F.Ms. The term F.M. first appeared and evolved in 1990s. It is suggested that F.Ms. are positioned on the same lines as development of museums, and that the field of museums and the field of landscaping is beginning to overlap. Concerning the role of museums, we examined the definition of museums in terms of conventional museums and regional planning. Next, the documents of 36 cases of F.Ms. are checked regarding their types and roles. Consequently, we found that while most F.Ms. cases have both the role of conventional museums and the role of regional planning, it is difficult to say that the role has some connection with the type. It seems that F.Ms. emphasize 'education' rather than 'collection', 'pleasure' and 'research', compared with conventional museums. In addition, the role of regional planning is strongly expected. In many cases, the F.M. is expected to be a method of regional management, not merely a museum. In order to use F.Ms. for regional planning and landscaping effectively, it is desirable for F.Ms. to be defined from this viewpoint. For this purpose, it is necessary to determine the extent of F.Ms. The problem is which extent to choose, geographical unity or administrative border. Hence, further comparative research is needed clarify the association between the extent and the identity in order to establish a more effective size of F.Ms.

  • The present study aims to provide efficient regimen by means of the Oriental medicine tool to measure Yangseng developed to fit the situation of Korea. For this purpose, the elderly people aged older than 65 were selected and their level of Yangseng was compared and analyzed depending on their perception of health. From the study, following conclusions could be drawn: 1. The total subject of study were 763 consisting mostly of the illiterate and spoused with disease but without leisure activities. 2. Most of the subjects were found to have little confidence with their health. With regard to their level of Yangseng, higher points were rated in morality yangseng, followed by activities & rest, diet, mind yangseng, sleep, seasonal yangseng, exercise and sex life in order. 3. By socio-demographic characters for the group with confidence in health, there were more male than female, with spouse, disease and leisure activities currently. In the group without confidence in health, there were more female, without spouse and leisure activity but with disease presently. 4. As for the level of Yangseng in the group with confidence in health, higher points were recorded in morality yangseng, followed by activities & rest, mind yangseng, diet, sleep, exercise and sex life in order. In case of the group without confidence in health, higher points were recorded in morality yangseng, followed by activities & rest, diet, mind yangseng, sleep, exercise and sex life in order. From the above outcomes, it would be necessary to motivate the subjects to have a renewed concept for health and efficient regimen. Continued and repeated eforts should be made to fill the gap in the study using the tool to measure Yangseng of the elderly people.

  • Due to development of modern medical services and economics, people raised expectation and demand about medical services from previous disease treatment to comprehensive health care covering prevention and health care. Responses of each medical facility to these social needs and the evolution of concept of medicine rapidly occur. The health examination centers are being operated with the purpose of health examination and this trend is reflected on several aspects such as the size of the facilities, function and configuration of space in health examination centers. Thus, health examination centers consisting of various space systems appear, but this trend and interpretations are lacking. Therefore, the purpose of this study is to draw trends of system through analysis of types and its evolved space systematic analysis and establish it. Analysis targets were classified into small, medium and large groups by sizes based on number of space and a total of 12 health examination centers in four for each category were selected. As research methods, functional relationship of space was examined through analysis of type in which segmentalized type tools were applied in local units. The flow diagram was established based on direction turning point and was classified into sub-flow and main-flow in local units and the systems between local units were derived. Finally, the results of this study can be summarized as the following three results. 1) The space connection system of health examination center showed four systems such as circulation, independence, continuation, and network. 2) Local type indicators and global type indicators which were evolved more from limitation of type analysis tools in existing research were derived so that more systematic analysis could be made. 3) Network system is distributed approach system and space for each function is formed around public space.

  • The purpose of this study is to clarify the historical circumstances under which the Korean Pavilion was established at the 1900 Paris Exposition Universelle, and the construction process and design features of the pavilion building. At that time, even though Korea faced difficulty due to lack of experience in the world exposition and funds, Korea attempted to positively participate in the international cultural event by establishing the Korean Pavilion under an official contract with assistance of the French Government. Moreover, the Pavilion shows significant architectural features which had not been shown until then in terms of the structure and design of the pavilion building. In this connection, in this thesis, among others, the historical circumstances under which the "Korean Pavilion" was established at the 1900 Paris Exposition Universelle, and the construction process as well as the process and features of the draft design prepared at an early stage by Baron Delort de Gleon on the part of France among the above parties to the project for construction of the Korean Pavilion, which have never been addressed in the field of architecture or interior due to lack of existing data, will be clearly studied based on relevant literatures. According to analysis of the study, it reveals that the representation method for the Korean tradition of Korean Pavilion designed by Baron Delort de Gleon was based on the Chinoiserie, the style widely seen in Europe. In addition, Delort de Glean's commerce-oriented concept is integrated into the design of the Korean Pavilion as well.
