This study was to analyze factors of the body form and factors of bodice pattern through a surface developement figure for the tight bodice pattern design. Fifty replicas of the trunk surface were made by applying a surgical tape method of female subjects between 18 and 24 years old. The result was as follows: 1. The gaps between direct measurements and measurements of the surface development figure were regarded as allowances for the tight bodice pattern. 2. There are four factors of body form selected by factor analysis. The 1st factor signifies th degree of fatness in the upper body. The 2nd factor signifies the length of the upper body. The 3rd factor signifies the part of the front shoulder. The 4th factor signifies the part of the neck. 3. There are high correlations between center back line of the surface development figure and back length line side line front length line back neck depth back upper chest depth. There are high correlations between back bust line of the surface development figure and back interscye breadth line back upper chest line back armhole line. There are high correlations between front bust line of the surface development figure and front upper chest line front interscye breadth line front armhole line front neck breadth 4. The regression expressions of measurements of the surface development figure of the upper body were analyzed as(Fig. 3).

The purpose of this thesis is to trace the development of cotton Early Chosun Period by examining the historical literary sources : such as production of cotton various uses of cotton trade with other countries The developement process of cotton fabrics during this period can be divided into three stages. The first stage which can be discribed as a settling period lasted 27 years from A.D. 1392 to 1418. In this stage cotton fabrics were just about to be used as fabrics for popular clothing. The second stage which can be discribed as a developmental period lasted 50 years from A. D.1418 to 1468. In this stage cotton fabrics were mainly produced in the southern parts of the country which are Kyungasng-Do, Choongcheng-Do and Jeunla-Do. And cotton fabrics were used not only by the common people but also by the royal family. The third stage, that is the last one was an extensive period and lasted from A.D.1469 to 1592. In this stage as the demand for cotton fabrics greatly increased the production from southern parts of the country fell in short of the supply needed. Therefore the production was extended to the northwestern parts. In addition cotton fabrics finally came to be used as money to value the goods.

This study is to develop evaluation indicator for brand self-diagnosis of agricultural management organizations and analyze importance weight to be used in the field. Self-diagnosis evaluation indicator of brand equity of agricultural management organizations were selected by brainstorming of brand specialists. As a result, six evaluation indicator of communication, organization, responsiveness, clarity, customer relations and quality control were selected. Importance weight of self-diagnosis evaluation indicator of brand equity of agricultural management organizations was analyzed by AHP(Analytic Hierarchy Process) and Fuzzy AHP. The results of Fuzzy AHP were as follows. Communication for 13.9%, organization for 6.5%, responsiveness for 9.9%, clarity for 7.7%, customer relations for 26.5%, and quality control for 35.5% respectively. In order to enhance brand equity of agricultural management organizations, first, cultivation guidelines should be set up to produce equal quality products among members. Second, quality levels need to be subdivided, brands and packages should be different by level. Third, persistent efforts to find new clients and distributors. Fourth, various efforts to maintain the existing excellent clients and distributors.

Due to a modern medical technology developement and the stability of social welfare policy, the current population of old person in Korea reaches to 550 million with the increasing elderly population rate(11.8%). But the living standard of elderly people does not meet to their needs of convenience on the proportion of the percentage of elderly people. Accordingly, this study mainly focuses on the research to find various advanced IT technologies to make elderly people more convient to use. Advanced IT industry makes it possible the convinence of elderly people using NFC, Wi-Fi, cardiac measurement technology.

The '凸'-shaped, the '呂'-shaped and the hexagonal-shaped pit houses were excavated at the Youngdong area, some location along the upper the Imjin River and Han River between the Iron age and the kingdom of Hanseong Baekje. The aim of this study is to analyze various structural system and developement of the pit house with rectangular plan. It is considered a matter in all its aspects which are plan, scale, aspect, pillar holes, carbonized wood and several traces. These pit houses removes the pillar on the inside or it reduces to secure a wider space, it pursued the chamfered corner, the change of the front, the entrance fixed. Also these adopted diverse structural systems(the chuandou structure, the structural system of columns and beams and a bearing wall). But in the course of time, the Korean wooden architecture is developed gradually the structural system of columns and beams. It is presumed the result that overcome the limit with the close space and pursue the flowing space and compose a group of organizable buildings.

A new type $Cu_{x}N/Cu/Cu_{x}N$ thin film electrode material with high adhesion to glass was developed by the dc reactive planar magnetron sputtering system for the PDP(Plasma Display Panel). The adhesive force of the $Cu_{x}N$ thin film was in the range of $20{\sim}40(N)$ under the conditions of the $N_2$ partial pressure of 15%, discharge current of 70mA, discharge voltage of 450V and substrate bias voltage of -100V. The adhesive force was depended on the $N_2$ partial pressure, discharge current and substrate bias voltage.

변전소용 축전지는 변전소 AC 상용전원이 정전되었을 때 직류전원을 중단없이 공급하기 위한 비상용 전원설비로써 대부분의 변전소에서 납축전지를 이용하고 있으나 환경유해 물질 배출, 짧은 수명과 유지보수의 번거로움 등 설비 운영상의 문제점이 있다. 최근 2차전지는 휴대폰, 노트북 등 휴대기기뿐 아니라 전기차, ESS 등 산업분야에 리튬이온축전지의 사용이 확대되며 관심이 높아지고 있는 추세이다. 한전에서는 2008년부터 154kV 용산 등 4개 변전소에 납축전지 대신 리튬이온축전지를 설치하여 시범사용을 지속해 오고 있으며 향후 신설되는 변전소와 축전지 노후교체가 필요한 변전소에는 리튬이온축전지를 적용할 계획이다. 본 논문에서는 기존 변전소용 납축전지의 운영상 문제점 해소와 함께 친환경 고성능, 콤팩트형 2차전지로 각광받고 있는 리튬이온축전지 도입을 통한 변전소 비상전원용 축전지 개발 적용방안에 대해 소개하고자 한다.

In this paper a remote monitoring and control system using SNMP(Simple Network Management Protocol) for UPS (Uninterruptible Power Supply) systems is proposed. The local remote system by RS-232 or RS-485 communication code or the wide remote system by modems is used for conventional remote monitoring & control system for UPSs. But recently because of communication cost and long distance the system is changed to remote control systems through internet and information communication network. And serial communication method by RS-232 or RS-485 is used between agent and UPSs. In this study. we designed and developed the system which is able to control UPSs and to monitor errors. statuses and actual values transmitted from UPS through internet.

In order to maintain and evaluate the adequate humidity and temperature of a museum, the data of these should be periodically monitored and accumulated. For this purpose, We have designed the interpretation method of charts of the widely used thermo hydrorecorder at the museum, and developed the computer-based program (name of the program : HATH interpretation program). This method is as follows;The recording of thermo hydrorecorder(model ; Sato R-704) Input a through scanner (UMAX type), and was transformed into numerical value and was processed the statistics by HATH interpretation program. Output can be present the numerical value and the graph which are classified by a day, a month, and a year. By this method, the humidity and temperature data which were taken from 12points in the exhibition case, storage and outdoor of the Ho-Am art Museum in 1995 were processed. At the results, its ability for fast processing, management and analysis of the data was proved to be excellent.
