The purpose of this study is to provide some information for the proper education on clothing wearing habits so that the education may be performed in the direction of social needs according to the social change and in the direction of the needs and interest of the high school girl students in their adolescence by being conscious of the influence of clothing on the high school girl students. I have used questionaire as an instrument of measurement. The length of the time of survey is from February 11, 1991 to February 28. The subjects are 544 first grade girl students of general high schools in Cheong-Ju, Choong-Ju, and Je-Cheon. The analysis of the data includes frequency, percentage, average person's Correlation Program, t-test, ANOVA, Scheffe's test. The conclusion of this study is as follows: The first, it is shown that (l)students's interest in the design and fashion of clothing is significantly related to the socio-anthropological and socio-psychological factors such and the education level of their fathers, the education level of their mothers, monthly income of their homes, the clothing habits of their home economics teachers, the subjects which they are interested in, their average scholoary achievements, their religious background, and whether they have boy friends or not, etd. (2)students' interest in purchasing of clothing is significantly related to the socio-anthropological and socio-psychological factors such as the education level of their fathers, the education level of their mothers, monthly income of their homes, the clothing habits of their home economics teachers, the subjects which they are interested in, their average scholoary achievements, and whether they have boy friends or not, etc. (3)students' interest in the social-psyclological aspect is significantly related to the socio-anthropological and socio-psychological factors such as their living area, the clothing habits of their home economics teachers, etc. (4)students' interest in the clothing construction is significantly related to only the clothing habits of their home economics teachersl. (5)students' interest in the clothing management is significantly related to the socio-anthropological and socio-psychological factors such as the education level of their parents, the age of their mothers, their religious background, and their sisters. The second, as for the interest of the high school girl students in clothing, it has been shown that those who wear school uniforms tend to have more interest than those who wear free-choice clothes in such areas as shopping, the construction, and management. As for the other two areas, that is, disign and fashion, and the interest in socio-psychological dependence there has been little meaningful difference between the two groups, while the uniform group has shown more interest than the other group. The third, the interest of hish school students in clothing is considered to be most seriously influenced by their socio-psychological dependence out of five areas of interest. It has been shown that the proportion of the content dealing with clothing wearing life in the high school home economics texbooks in relatively small, especially in such areas as socio-psychological dependence, shopping, management, and design and fashion except in construcion.

Background and Objective : Laryngeal Papillomatosis (LP) is the most common benign neoplasm of the larynx, but it tend to recur and it makes eradicating difficult. Meticulous $CO_2$ laser excision has been the most effective treatment to date. This article analyzes the clinical feature and therapeutic results of 42 LP patients who were undergone $CO_2$ laser excision. Methods : Forty two patients with recurrent LP were treated with $CO_2$ laser. And their medical records were reviewed retrospectively. Demographics, chief complaints at onset, initial distribution of papillomas, number of operations performed on each patient, and current results were evaluated. Results : Male in their twenties and forties are dominant in number in patient number. Most common site was anterior one thirds (69%) of glottis area (86%). LP recurred in 17 cases (40%), and in 4 cases, the lesion extended over the original margin. Patients were undergone surgery $1.62{\pm}0.87$ times, $2.53{\pm}0.72$ in recurred cases. Mean relapsing time was 6 momths (from 1momth to 8years). Ant. laryngeal web occurred in 2 cases (4.8%) and 1 case was combined with squamous cell carcinoma. Conclusion : Meticulously performed $CO_2$ laser excision can achieve significant voice and airway improvement and clinical cures. The $CO_2$ laser through microdirect laryngoscopy allows more precise and bloodless removal of papillomas.

Using the optical data from the EUMELI 3 and 4 missions, the optical properties are discussed in relation to primary production in the oligotrophic zone of the Eastern Atlantic Ocean. The depth of euphotic layer $(Z_{eu})$, the total accumulated concentration of pigment $(C_{TOT})$ and the concentration of pigment (C) are 88m, $12.4mgm^{-2}\;and\;0.14mgm^{-3}$, respectively for the EUMELI 3 mission and 101.7m, $10.0mgm^{-2}\;and\;0.10mgm^{-3}$, respectively for the EUMELI 4 mission. The concentration of pigment is higher in autumn (EUMELI 3) than in spring (EUMELI 4). This indicates that the concentration of photosynthetic pigment has a close correlation with vertical attenuation coefficient $(K(\lambda))$ that changes seasonally in the euphotic layer. While the spectral distributions of downward Irradiance$(E_d)$ for the wave length of 470nm increase with depth, those of upward irradiance $(E_u)$ for the wave length range between 410nm and 490nm are constant, because the study area is covered with the blue and clear oceanic deep waters. The vertical attenuation coefficients of downward irradiance $(K_d)$ and upward irradiance $(K_u)$ have low values between 0.02 and $0.06m^{-1}$ due to the low absorption and scattering by the photosynthetic pigment of phytoplankton. Therefore this zone has the characteristics of the case 1 waters with low concentrations of photosynthetic pigment, and can be classifed into IB.

GIS를 이용하여 환경지질도의 분야별 목적도 및 종합도 작성 기술이 본 연구를 통하여 국내에서는 처음으로 개발되었다. 환경지질도는 현재 국내외적으로 자연환경 변화에 따른 지질재해 및 환경오염 등을 분석할 수 있는 중요한 자료로써 활용되고 있다. 그러나 환경지질도 작성을 위해서는 우선적으로 연구지역에 대한 환경지질 분석과 야외조사 자료를 토대로 대상 지역의 자연환경 변화를 유발시킬 수 있는 환경지질 요소들이 정량적, 정성적으로 분석되어져야 된다. 환경지질 자료들은 목적에 따라 차이가 있지만 방대하고 다양한 분석 자료들이 포함된다. 국내의 환경지질도 작성기관인 한국자원연구소에서는 이러한 환경지질도 작성기술을 체계적으로 정립시키고져 당연구소 환경지질연구 그룹내에 GIS를 이용한 환경지질 정보시스템을 구현하고 청주지역을 대상으로 환경지질 데이타베이스를 구축한 후 시범연구를 실시하였다. 환경지질도 작성 기술개발에 의하여 생산된 목적별 도면들은 지질공학도, 지질재해도, 지표유출량 분석도, 토공량 및 절취 난이도, 지하수 보호 및 관리 분석도 등이며, 이들에 의한 2차 GIS 지도모형연구를 통하여 토지활용 우선 순위 분석을 위한 종합 환경지질도가 완성되었다. 데이타베이스내에 구축된 일부 환경지질자료들은 타기관에서 제작된 자료들을 활용하였으며, 이로 인한 자료들의 일부 부정확성때문에 금번에 작성된 몇몇 목적도들은 추후 환경자료의 보완 및 갱신에 의하여 수정된 도면들이 재작성 될 것이다. 본 연구결과는 앞으로 국토개발 계획 및 환경영향 평가를 위한 신기술로 활용될 것이며, 당연구그룹에서는 이 기술을 기반으로 환경지질 분석을 위한 GIS전문가 시스템을 구현시킬 예정이다.

In this study, life cycle cost (LCC) is analyzed according to insulation panel system type using a deterministic LCC analysis method. Through this analysis, it was found that the construction cost in the deterministic LCC analysis for Ceramic panels was low compared to the construction cost for metal and stone panels. Also, the difference in cost between the Ceramic panel and the metal panel was about 2 times. In the area of maintenance cost, it was found to be similar to the previously analyzed construction cost, in which the metal panel has the highest cost due to the high cost of construction and the frequent need for maintenance. In the case of the stone panel, a small difference in cost is shown compared with that of the Ceramic panel, but the cost is higher than the Ceramic panel. Regarding the cost of waste disposal, the Ceramic panel can reduce the cost by at least 1.5 times and up to 2 times compared to other panel systems. Finally, in the analysis of sensitivity according to changes in discount rates, the Ceramic panel and metal panel systems have a similar cost, and the cost of the metal panel is a bit larger than that of other panel systems. Thus, in the subjects used in the analysis, the Ceramic panel system shows the highest economic benefits.
