The ceremonies were roughly categorized into four： coming of age, marriage, funeral and ancestral worship. Among them, the funeral was a representative example to show ancestral worship. As it symbolizes the worship to ancestors, its procedure was complicated and formalized. It was undoubtedly certain that formalized mourning dresses and complicated table setting for sacrificial services to ancestors were burdens. Although what was symbolized by mourning dresses was different depending on the wearers purposes, it was thought that no clothing had such unusual symbolism as mourning dress. When the composition of mourning dress was examined, it was shown that Taoism, family relation of Confucianism or symbolic clothing system of Shamanism were combined. Mourning dress first represented the Confucian idea of ancestral worship. For the composition of clothing in which a shamanistic element was inherent, forms of birds were used to guide the dead soul to the other world. In cutting out mourning dress, opposite concepts of Yin and Yang, and closure and openness were used to show a harmony between heaven and the earth. Male and female were represented through sewing techniques. The period of observing the mourning period depended on the degree of kinship. The degree to which the clothing was loose indicated the degree of sadness and kinship. Load blocks and tear pads indicated the degree of sadness. In considering the above indicators, family relation and filial piety to ancestors had a great effect on the form and details of mourning dress. Shamanistic elements as well as Confucian ones were inherent in mourning dress, which resulted in the combination of Taoism and Confucianism.

The present study deals with the experimental facility for PSD (POGO Suppression Device) performance test systems. Basically there are two methods to pulsate the system; whole-feeding-system pulsation and working-fluid pulsation. The latter method adopts either a piston-type pulsator or a restrict-type pulsator. The working-fluid pulsation using a restrict-type pulsator was considered to be the most appropriate experimental system to study the effects of the primary parameters, and a practical design of the system was proposed. Also, the experimental facility adopts the ball valve type pulsator considering the leak problem of the plate type pulsator.

In this study, complaints from visitors in the science museum satisfaction survey were categorized into four primary factors and ten sub-factors. This categorization aimed to provide recommendations for enhancing the Geochang Wolseong Space Creative Science Museum as an illustrative case study. Futhermore, the study examimed the relative importance of each factor by surveying 90 science museum visitors. The following results are obtained. Firstly, it was evident that the Geochang Wolseong Space Creative Science Museum requires urgent improvement. Certainly, in the primary factors, issues related to the utilization environment emerged as the most significant sources of dissatisfaction, while in the sub-factors, the adequacy of fees was identified as the most prominent concern. Secondly, through the result of the IPA (Importance-Performance Analysis) of the complaint factors, four primary issues were identified as top priorities for consideration: fare adequacy, lack of convenient facilities, in sufficient publicity, and a lack of distinctiveness compared to similar facilities. Lastly, when analyzing the relationship between complaints and overall satisfaction, factors related to human service, environment, and educational content had negative effects. In contrast, factors associated with science museum operation exhibited a different trend, suggestinga structural impact relationship with the overall impact of complaints.

This paper is aimed at analyzing the characteristics of Image-Meaning theory focused on image in the early days of the Joseon Dynasty and SongMing period. Zhouyi' theory in the early days of the Joseon Dynasty was constructed on the basis of Zhouyi' theory of SongMing period. The characteristics of Image-Meaning theory in the early days of the Joseon Dynasty can be explained largely by two routes. One is the perspective of critical succession on Zhouyi'theory of focusing on meaning that led Chengyi(程?) and Yangwanli(楊萬裏). As the representative of this route, Gwongeun and Toegye not only asserted Image-meaning theory focused on meaning, but also developed a perspective of taking all the image and meaning. The other is the active succession and creative transformation about Image-Meaning theory of Tushuxue that led Chentuan(陳?) and Shaoyong(邵雍). As the representative of that route, Yulgok and Yeohun explained the schematic diagram of the universe of the universe by using methodology of Tushuxue. Furthermore, they actively succeed Shaoyong' Zhouyi theory to expand Image-Meaning theory focused on number. In addition, Cho, Haoyi(曺好益)described the propositions - "meaning is not out of image area, image equipped with meaning all, then there is no law of limitation in image adopted theory. Those propositions are opposed to Chengyi(程?) and Zhuxi(朱熹)' ZhouYi' theory.

In this paper, optimum design process of ICP (Inductively Coupled Plasma) torch, which has been used widely in aerospace application, such as supersonic plasma wind tunnel, is presented. For this purpose, the behaviors of equivalent circuit parameters (equivalent resistance and inductance, coupling efficiency) were investigated according to the variations of torch design parameters (frequency, $f$, confinement tube radius, $R$ and coil turn numbers, $N$) in the basis of analytical and numerical MHD (Magneto Hydro-Dynamics) models combined with electrical circuit theory. From the results, it is found that equivalent resistance is increased with the increase of $f$ values but vice versa for equivalent inductance. For elevated values of $R$ and $N$, however, both parameters tend to increase. Based on these observations, ICP torch with a power level of 10 kW can be optimized at the design ranges of $f$=4~6 MHz, $R$=17~25 mm and $N$=3~4 to maximize the electrical coupling efficiency, which is the ratio of equivalent resistance to equivalent inductance.

This study is based on the assertion that science museums should consider visitors' views and expectations as they are not satisfied in many cases. In this study, we investigated 31 scientifically gifted students and 177 science high school students about their image of science museums. Using the questionnaire, it was found that only 51% of students visited science museums; however, the average number of visits was 4.2. This means that students tended to re-visit after the first visit of the science museum. Students had a 'good' image of science museums when they incurred hands-on experiences and observed new, interesting, curious and funny exhibits. And students had a 'bad' image of science museums due to the following aspects: lack of new and interesting exhibits, information and guide, diverse contents, and hands-on experience; deficiencies in environment; and inadequacy of the management, operation and composition of exhibits. Therefore, they hoped that science museums will provide more hands-on experiences and experiments, new and interesting exhibits, systematic management and composition of exhibits, information and guides, and a good environment. So science museums need to pay special attention to aspects like management, information guides and environment for the first-time visitors. Based on the above results, we suggested "Directions for a good science museum based on students' views". While asking students what topics they wanted to know and learn in a science museum, each student was given the choice of four topics; eventually, 2.9 answers overlapped for each topic. When classifying students' topics into four main themes for the Gwangju National Science Museum, the order from the most popular theme to the least one was 'science in everyday life', 'ocean/space/future science', 'light and science', and 'culture, art and science'. Among the topics mentioned by students, only 37% are exhibited in Seoul, Gwacheon, Daejeon, or Gwangju science museums. We hope that the results and research methods will be used for evaluation, re-construction, and reinvigorated presentation of science museums.

It is possible to distinguish X-ray events from non X-ray events in proportional conters using the method of rise time discrimination (RTD). In order to subtract non X-ray background, we have developed a simple RTD circuit which will be applied to the proportional counter planned for a sounding rocket experiment. The entire circuit consists of two parts ; the rise time measurement circuit and the time to amplitude conversion circuit which includes the self-calibration mode. From the test with X-ray detecting system, we obtained that the background can be rejected more than 80% in the energy band 2∼12 keV. However we confirmed that the RDT method is not proper to be used for the energy range above 12kV.

현재 국내에는 약 40여 개의 종합(관측실과 투영관이 있는) 천문시설이 운영 중에 있으며 새로운 시설이 꾸준히 추가로 건설 되고 있다. 그리고 교육과학연구원, 도서관 등 많은 시설에서 천문시설을 갖추고 교육에 활용하고 있다. 그런데 대부분의 천문시설에서는 별자리 설명, 천체투영관에서의 영상물 상영, 그리고 천체망원경을 이용한 관측실습 등 한정된 소재와 일관된 형식의 천문교육 프로그램을 운영 하고 있다. 하지만 국립과천과학관에서 방학 중 천문학교실을 운영해본 결과 좀 더 깊이 있는 천문학 교육에 대한 수요가 상당히 많다는 사실을 확인할 수 있었다. 실제 과학교육 현장에서는 여러 분야의 다양한 교육프로그램들이 개발되어 운영되고 있으나 천문학을 주제로 한 교육은 찾아보기 어려운 상황이다. 천문학은 새로운 연구 결과가 가장 활발하게 발표되는 분야들 중 하나로, 일반인이나 언론에서도 상당히 많은 관심을 보여주고 있다. 외계행성 탐사, 초신성 관측, 우주 가속팽창과 같은 최신 천문학 분야의 다양한 주제들을 이용하여 교육프로그램을 개발하면 일반인들에게 천문학의 내용을 알리는데 좋은 기회가 될 수 있을 것이다. 국립과천과학관에서는 방학 프로그램에 이어 조금 더 심화된 교육프로그램을 기획하여 운영할 준비를 하고 있다. 현재 국립과천과학관에서 준비 중인 천문교육프로그램을 소개하고 여러 사람들의 의견을 들어보고자 한다.
