As Confucian ideology dominated all over the society, the androcentric patriarchical society in the last of Chosun Dynasty produced the unequal power relationship between man and woman. It was traditional hostesses(kisaengs) who uniquely had an occupation among the women in this society. In modern society. they are reinterpreted as 'fashion leaders' or 'professional career women with expert knowledge and it caused a lot of the studies of them to be in a progression vigorously. Therefore this paper studied on the influence of the traditional hostesses(kisaengs) -who were educated and permitted in ther social activity formally in a Confuanism-governed society which forbided a woman to participate in a social activity and which did not gave ladies any formal education. The general hostess in the beginning time of the Chosun Dynasty imitated the hair shape of women in the yangban family which formed the highest class in the Chosun Dyansty and it reflected their aspiration for the highest social class. Howerver, coming into the last age of the chosun dynasty, a reverse phenomenon -that women in the yangban family imitated the general hostesses' hairstyle -occured due to the spread of a genre painting ＆ the concubine system. The general hostesses were educated systematically and did social activity and influenced hair shapes as they were independent economically and their influence in the part of hairstyle appeared as great and high EONJIN MEURI and as one-sided EONJIN MEURI. Regarding-as the result of this study on the influence of the traditional hostess's hair shapes on the ladies hair shapes in the last of Chosun Dynasty -that the traditional hostesse of the last age of chosun dynasty played a role as a fashion leader of the ladies at the same age. the general hostesses in Chosun Dynasty should be revaluated... And the study of ladies which were hidden behind the scenes of Confuanism should be made much more.

The optimization and microwave assisted extraction of stem bark of Terminalia arjuna, quantitative estimation of the marker compounds arjunic acid and arjunolic acid using HPTLC and the evaluation of free radical scavenging activity has been performed in this study. The central composite design was used for optimization and the values of parameters for optimized batch of microwave assisted extraction were 1000 W (Power), 3 minutes (Time) and 1/120 (Solid/solvent ratio). The solvent system to carry out the HPTLC was toluene: acetic acid: ethyl acetate (5: 5: 0.5) and quantitative estimation was done using standard equations obtained from the marker compounds. The in-vitro free radical scavenging activity was performed spectrophotometrically using ascorbic acid as standard. The value of estimated percentage yield of arjunic acid and arjunolic acid was 1.42% and 1.52% which upon experimentation was obtained as 1.38% and 1.51% respectively. The DPPH assay of the different batches of microwave assisted extraction and marker compounds taken suggested that the marker compounds arjunic acid and the arjunolic acid were responsible for the free radical scavenging activity as the batch having the maximum percentage yield of the marker compounds showed best free radical scavenging effect as compared to standard ascorbic acid. The $IC_{50}$ value of the optimized batch was found to be 24.72 while that of the standard ascorbic acid was 29.83. Hence, the yield of arjunic acid and arjunolic acid has direct correlation with the free radical scavenging activity of stem bark extract of Terminalia arjuna and have potential to serve as active lead compounds for free radical scavenging activity.

선진국에서는 1980년대부터 MVNO가 도입되었고 우리나라 학계에서도 2000년대 초반 이미 도입 필요성이 제기되었다. 그런데 2000년대 후반 통신비 인하가 주요 정책이슈로 등장하면서 이동통신사업이 개시된지 27년만인 2011년이 되어서야 MVNO가 도입되게 되었다. 2015년 4월에는 MVNO의 가입자수가 504만명으로 이동통신시장 점유율이 9%에 이르고 있으나 아직 많은 문제점을 노출하고 있다. 급속한 성장의 이면에는 저렴한 통신서비스를 바라는 소비자들의 욕구와 때늦은 MVNO의 도입이 자리하고 있다. 그리고 이통사들은 우월적 지위를 누리고 있는 한편 자회사를 앞세워 알뜰폰시장의 확보에 나서고 있어 중소기업의 입지를 약화시키고 있다. 정부의 적절한 개입이 지속되어야 할 필요가 상존하고 있다. 정부당국은 세계적인 MVNO 흐름을 조기에 인식하고 신속하게 도입할 필요가 있었으며 향후 이통시장의 경쟁환경조성에도 충분한 노력을 기울여야 할 것이다.

The purpose of this research is to measure the sensibility and preference of American consumers for domestically-manufactured cotton fabrics through 7-points scale questionnaires and the 4-dimensions and 8-axes system. The key words included such images as masculine-feminine, new-old, casual-classic, and ambiguous-orderly. The images of cotton fabrics were classified through a cluster analysis. This research also included an investigation of relationship between sensibilities for cotton fabrics and their physical characteristics. The sensibilities of cotton fabrics were classified into 4 groups: 'feminine sensibility,' 'masculine sensibility,' 'new sensibility,' and 'casual sensibility.' This result represents that American consumers' sensibility is simpler than Koreans'. The order of preference was 'feminine sensibility', 'masculine sensibility', 'new sensibility', and 'casual sensibility.' The sensibilities of cotton fabrics were explained significantly by stiffness, weight, weft density, value, and chroma. Specifically, those were more influenced by color characteristics such as value, chroma, and hue than by physical characteristics. We should be able to tell a difference in the reaction of a trading country's consumers and domestic consumers to domestically-manufactured cotton fabrics through comparing this research with the previous work(Shin & Lee, 2002). Additionally, we will be able to establish a basic strategy for successfully advancing Korean fabrics into the American domestic textile industry. In this way we can expect to increase the competitive power of our domestic clothes brands.

The power-train is the most important component of an agricultural tractor. In this study, the strength of the driving gear transmission of an 82 kW-class tractor was analyzed using equivalent torque during plow tillage. The load measurement system consisted of an engine revolution speed sensor, torque-meters, revolution speed sensors for four axles, and pressure sensors for two hydraulic pumps. The load data were measured during plow tillage for four speed stages: F2 (2.78 km/h), F5 (5.35 km/h), F7 (7.98 km/h), and F8 (9.75 km/h). Aspects of the gear-strength such as bending stress, contact stress, and safety factors were analyzed under two torque conditions: the equivalent torque at the highest plow load for the F8 speed stage and the maximum engine torque. The simulation results using KISSsoft showed that the maximum engine torque conditions had a lower safety factor than did the highest equivalent torque condition. The bending safety factors were > 1 at all gear stages, indicating that gear breakage did not occur under actual measured operating conditions, nor under the maximum torque conditions. However, the equivalent torque condition in the contact stress safety factor was > 1, and the maximum torque condition was < 1 at the first gear pair. The method of analysis using the equivalent torque showed lower stress and higher safety factor than did the method using maximum torque. Therefore, when designing a tractor by applying actual working torque, equivalent torque method would support more reliable product development.

The purpose of this study was to evaluate the PTO severeness for an agricultural tractor during disk plow and rotary tillage. The PTO load measurement system was constructed with data acquisition and a PTO torquemeter. Field experiments were conducted at a combination of traveling speed (L3 Low, L3 High) and PTO speed (P1, P2). The load spectrum was generated using the rain-flow counting method, and the SWT method was used to consider the range and mean of the PTO load. The damage sum was calculated by applying a modified miner rule, which is a cumulative damage law. The relative severeness was expressed as the ratio of the lowest damage sum. Relative severeness was higher with the lower PTO gear stage, and higher driving gear stage and it was approximately 40-102 times higher for rotary tillage than disk plow tillage in the same gear stages. The relative severeness was 1010.12 in the rotary tillage under L3 High P1 based on the disk plow tillage under L3 Low P2.

In dismantling factories for recycling, it is important to input actual working data to a personal computer (PC) in order to monitor the work results and related recycling rate of the inputs. This should be performed with a keyboard, a mouse, or other devices. But when a worker is working in the factory, it could be bothersome or time consuming to go to the PC. Especially, workers who works at dismantling factories have a generally low education level are scared to use a PC, which could be used as a pretext for not using the PC. In some cases, data input is performed by a worker after the day's job. In this case, it could take additional time, the worker can make more mistakes, and the data could be unreliable. In this study, we developed a man-machine interface (MMI) device using a safety helmet. A joystick-like device, pushbuttons, and a radio frequency (RF) device for wireless communication is equipped in a safety helmet. This MMI device has functions similar to a PC mouse, and it has a long communication distance. RF is used because it consumes less battery power than Bluetooth. With this MMI device, workers need not go to a PC to input data or to control the PC, and they can control the PC from a long distance. The efficiency of PCs in a factory could be increased by using the developed MMI system, and workers at the dismantling factories could have less reluctance in using the PC.

The purpose of this study was to develop prevention and educational programs for battered women. The first stage was to assess battered women's health status and health needs. The second stage was to develop prevention and educational programs to improve battered women's health. A survey research design was used to gather data from June-November 1999 by the counselor. Research sample was recruited from shelter and women's counseling centers in Seoul, Inchon, Chooncheon, Taejeon, and Jeoju. Trained counselors contacted 218 women, who agreed verbally to participate in the study. The researcher did a literature review and developed the tool used. We did ten pretests and three counselors checked the tool for content validity. The reliability and validity of the instrument were acceptable. The second stage of the research consisted of lay-professional groups discussing the abuse problems and possible solutions. Each group had five professionals (counsellor, nurse, minister, psychiatrist, social worker) and five women who have experienced battering from her husband in community. Result of the survey and two(lay persons and professionals) group discussions showed that victims need more assessment of physical, mental and spiritual needs. Victims were beaten more often during their pregnancies than at other times. Various kind of strategy were frequently utilized, but still the number of women abused and suicides committed increased. Both studies showed that the women experienced severe beating, that they felt powerless, that they need to understand that society abuser characteristics, that they lack a protection support system and that society lacks would an understanding of battered women. Based on the result of both studies, we developed model for prevention and education of battered women. This educational program will increase women s power to solve the abuse problems. The ultimate goal of the program is to develop a one-stop center to give wholistic approach care to women in abuse situations.
