This study examined how Chipogwan[緇布冠] with such a long history has been changed in China and Korea. With regard to the name, material, use and form of Chipogwan, the results of this study is summarized as follows. Chipogwan was mentioned continuously in ancient books of ceremonies and literature from the Tang dynasty [唐代], but from the Song dynasty [宋代] new name Chigwan [緇冠: a black hat] appeared besides Chipogwan. The two names were transmitted to Joseon dynasty [朝鮮] and used together until the mid Joseon dynasty, but from the 18th-19th centuries, Chipogwan was adopted according to ancient ceremonies and this name has been used continuously until today. The change of the name reflects the change of the material. Ancient Chipogwan was made of hemp [布] but when the term Chigwan appeared in the Song dynasty it was made of paper and Sa [紗: a 2-end simple gauze]. As other materials were added to hemp, po (布) was omitted from Chipogwan. As to the use of Chipogwan, it was a coronet used in purification ceremonies [齋冠] in ancient times. Then, it was used as Chogagwan [初加冠: a first hat putting on] in coming-of-age ceremonies [冠禮] from Zhou dynasty (周). During the Song and Joseon dynasty, Chipogwan was used in coming-of-age ceremonies as well as in daily life. As to the form, Chipogwan in ancient books of rites and the Song dynasty was a small coronet covering the topknot. In the Joseon dynasty, the form of Song dynasty was followed until the mid period, and then after the mid $18^{th}$ century, another form was proposed according ancient books of rites and an independent form of ceremonial coronet appeared that covered the entire head rather than covering only the topknot.

The purpose of this study is to determine how the people's view on afterlife affects their perception about shrouds. As part of analytical research, the survey was carried out to take a look at the basic thoughts that average persons have on afterlife. This paper also performed the survey on what the shroud reminds the subjects of. Specifically, the questionnaire survey was conducted to see what the people think the necessity and appropriate cost of shroud and see if they have any plan to get it provided in detail. Data from this work were statistically processed and empirically analyzed. Findings of this study can be summarized as follows. As to the funeral methods, the subjects in this work preferred cremation to burial. It was found that they recognized shrouds as necessary, but they did not have a thought in a serious manner that the suit for the dead would affect the repose of the dead and guide his or her soul to the heaven. Those respondents did not have any immediate plan to purchase shrouds, either. However, they considered the price of shroud as most important when they might come to choose the garment. With regard to the quality, it turned out that they preferred the domestic shrouds whose material are natural to those from foreign country. Also, they opted for such a kind whose shape is not so different from that of casuals they would usually wear and whose color is same to the main material of the original garment. The common material preferred most by the subjects was a hemp. The subjects' view of afterlife was not greatly related not only to how much they recognized shrouds as necessary but also to their preference for materials and patterns. On top of this, their unique taste for particular types of shroud was found to be significantly dependent on whether their view of afterlife is positive or negative, whether they firmly believe in afterlife, whether they take the absolute predestination and whether they accept the prayer-effect relationship in terms of psychology.

본 논문은 다중 도체 전송선 해석법과 chain matrix 알고리즘을 이용하여 twisted cable과 같은 비균일 전송선의 EMP 결합을 해석하였다. 전송선의 EMP 결합 해석을 위해 BLT(Baum-Liu-Tesche) 해석법이 널리 사용되고 있으나, twisted cable과 같은 비균일 전송선에 기존의 BLT 해석법을 바로 적용하기는 어렵다. Twisted cable과 같은 비균일 전송선을 해석하기 위해 수많은 작은 길이의 균일 전송선으로 나누어 모델링하였으며, 전체 비균일 전송선의 결합 특성은 각각의 균일 전송선의 EMP 결합 분석을 통해 최종적인 전송선의 결합 특성을 구함으로 써 가능해진다. 이러한 비균일 전송선 EMP 결합 해석 기법을 검증하기 위해 균일 전송선에 대하여 기존의 BLT 해석 결과와 비교하였으며, 제시된 비균일 전송선 EMP 결합 해석 기법을 지표면 위에 놓여 있는 twisted cable에 적용하여 대기 중의 핵폭발에 의한 HEMP(High altitude Electromagnetic Pulse)와 같은 매우 강한 펄스가 입사되었을 때, 전송선에 연결된 부하에 유기되는 전류(또는 전압) 응답을 분석하였다.

The utilization of non-woody fibers with the fast growing annual plants has occurred in the paper industry to replace wood and preserve environment of the earth. The non-woody fibers generally used for papermaking are paper mulberry, gampi, manila hemp, rice straw, bamboo, and coton linter etc.. Recently Kenaf has been spot-lighted for the same application. Kenaf is an annual plant of Hibiscus species of Malvaceae family. Kenaf, a rapid growing and high harvesting non-woody fiber plant, was identified as one of the promising fiber sources for the production of paper pulp. This study was carried out to investigate the pulping characteristics of Kenaf bast fiber for Hanji (traditional Korean paper) manufacturing by different pulping methods, such as alkali, alkali-peroxide and sulfomethylated pulpings. It was possible to make superior grade of Hanji. Especially sulfomethylated pulping was resulted in superior pulp in terms of higher yields and qualities in comparison to those of the other pulping methods. Hanji from sulfomethylated pulp was shown the highest brightness of over 60% and higher sheet strength. In addition, the morphological features of pulp fibers (pulp compositions) affect to the sheet properties. Therefore the effect of fiber distribution index(FDI) which was calculated from the data of Confocal laser scanning microscopy(CLSM) on the sheet properties of Kenaf Hanji was also discussed.

This paper researched and compared the Jangsam religious costume, of Buddhism in Yeongsanjae with that of Shamanism in Gutgeori. Jangsam is a full length, flaxen hemp dress used in both religions. (Ed-please amend this sentence as necessary but note that it is essential to give some description of the costume here for non-Korean readers) The religious point of view can cause Jangsam's features to differ Jangsam's meanings are as follows. First, the purpose of wearing Jangsam in both the Buddhist priest's and Shamans' costumes is to gain power from the Almighty in order to maximize the religious effect. Second, Jangsam in the Shaman's costume features universality mixed with Buddhism and folk religion and becomes symbolic in Buddhism. As society disregards Shamanism, it has become combined with Buddhism. Third, Jangsam for Yeongsanjae or Chukwon Gut has kept its religious specialty as a Pyoeui despite various modifications.

This paper looks into the field inside the wide rectangular box structure that is excited by the High Power Electromagnetic(HPEM) source as a potential threat to electric grid and communication networks causing malfunction or destruction. The rectangular box is assumed power/ground planes and its internal field is calculated by the cavity model with the lightning strike excitation as an HPEM pulse. The accuracy of the calculation method employed here is validated through a $156mm{\times}106mm{\times}508{\mu}m$ parallel metallic plate case which is manufactured and tested, and is applied to the size of a building. With the help of the cavity model that takes into account loading, the level of the electric field is shown to decrease when a metal pillar is loaded between the power and ground planes.

Objective: The aim of this paper is to introduces Hyundai Heavy Industry's ergonomic risk assessment tool, H-OWAS, which is considering work load and frequency compared to the OWAS. Background: As prevalence of work-related musculoskeletal disorders(WMSDs) in ship building industries has been much higher than that in other industries, most of the large scaled corporations have implemented their own prevention program since legislation on the prevention of WMSDs had introduced in 2003. Method: This paper introduces WMSDs prevention program, HEMP(HHI Ergonomics Management Program) which consists of risk assessment, improvement efforts of working environments, medical treatment and training/evaluation and describes how to operate the program. We also describe application of OWAS method considering work load and frequency for risk factor analysis(H-OWAS) and shows methodology for assessing the ergonomic risk factor. And comparison of the assessment results between OWAS and H-OWAS is carried out by statistical analysis. Result: There was statistically significant difference in the assessment results between OWAS and H-OWAS, and regression shows H-OWAS explains the borg's scale of perceived exertion more clearly than OWAS. Conclusion: H-OWAS has been proved more effective tool than OWAS to evaluate ergonomic risk factor under real working condition. Application: H-OWAS can be widely applied to the many other companies when implementing the ergonomics risk assessment.

This study was carried out to investigate the characteristics of the lining papers which had been separated from six pieces of paintings and calligraphic works of the 18th and the 20th century. A total 20 kinds of lining papers were examined on the physical properties, colors, fiber morphology, and color reactions. The grammage and thickness of lining papers which had been used hanging-scroll type works were higher than those of folder types. On the other hand, the grammage and thickness of the first layer lining papers which had been separated from silk ground works were lower than those of paper ground works. All kinds of lining papers were colored from yellow to yellowish red because of unbleaching and deterioration. Through the examination on fiber morphology and color reactions, lining papers were verified that all of those were made from paper mulberry bast fiber but the first layer of the Mukjukdo. The lining paper which of the first layer of the Mukjukdo was verified that it was made from mixture of paper mulberry, hemp, and spruce pulps.
