Objectives : The purpose of this study is to find the effects of Sa-am liver tonifying and sedating acupuncture on radial pulse. Methods : Sixty healthy people were divided into a liver tonifying acupuncture(LTA) group, liver sedating acupuncture(LSA) group, and control group. The LTA group and LSA group received acupuncture for 20 minutes with a supine position. The Control group took a rest without receiving acupuncture. Radial pulse was measured by three dimensional pulse imaging system(DMP-3000) at four different time points (before, right after, 30 minutes after, and 60 minutes after acupuncture). We compared the three groups and figure out determined the parameters which significantly changed after acupuncture treatment. Results : 1. Pulse period, T1/T, T4/T, (T-T4)/T, T4/(T-T4), T5/T significantly changed after acupuncture. 2. H4, pulse area, systolic pulse area, diastolic pulse area, radial augmentation index(RAI), and pulse power volume / min significantly changed after acupuncture. 3. Frequency of Fourier components, ratio of frequencies of Fourier components, magnitude of Fourier components, and ratio of magnitudes of Fourier components significantly changed after acupuncture. Conclusions : LTA and LSA have an effect on the radial pulse parameters. Further studies on radial pulse change using Sa-Am acupuncture are needed.

This study is aimed to suggesting a hypothesis about the process of improvement of houses of the Korean-Chinese, comparing how Han Chinese and Korean-Chinese houses changed in Yanbian Area of China. This draws the conclusion by analyzing the field survey about residence of the Han Chinese and the Korean-Chinese in Yanbian Area of China. First of all, the characteristic of residence style change and the plan of rural houses of the Han Chinese are in the following. The plan of houses has been changed from allocating rooms from side to side with the kitchen as the center to linking each functional spaces through the aisle. And the main bedroom of houses becomes the central space for family members instead of Kang (partial Ondol) by expanding the floor heating system under the whole floor in houses. Next, the feature of residence style changes of the Han Chinese and the Korean-Chinese is as follows. In 1970s barns disappeared from houses of the Korean Chinese, but houses of the Han Chinese were not much changed. From 1980s to 1990s, spaces linking each rooms with aisles had appeared for comfortableness of residence and respecting each individual's privacy. On the other hand, The houses of the Korean-Chinese make a whole big space by getting rid of walls between the rooms. And after 2 thousand years later, Han Chinese houses have a bedroom with floor heating system. Both houses of the Korean-Chinese and the Han Chinese are changed to have a residence style which taking sedentary style and standing style.

This study analyzes the common space of the high schools before and after the decade of 2009 which starts Subject-centered clusters school plan, and proposes the direction of common space planning for the future. Based on the floor plans of high schools awarded as excellent school facilities every year, first, types and numbers of common space, second, area ratio between common space and program space and also moving space and staying space, third, space connections were analyzed for tracking the change of the relationship between common, staying and program spaces. The study results demonstrated that types, numbers and area ratio of the common space were increased as the years go on. Especially, the area ratio of staying space was dramatically increased after 2009 and this result was caused by the home-base, alcove space, and hall that were adopted for subject-centered clusters planning after 2009. Connecting diagram of staying area and program spaces also shows the spaces related to staying area were changed from a classrooms and administrative office etc. to a library, gym, and seminar rooms etc. In case of staying area, it would have a value as a common space for various student activities such as group activities, meetings, and multi-uses. Because student activities would be changed and encouraged depending on the location, sizes and program spaces around staying area, it should be emphasized that the planning for staying area is critical for future school design.

도시공원은 도시 내 생태적 기능과 함께 일상생활의 여가공간 역할을 담당한다. 도시공원은 공원을 방문하는 이용자의 수요를 반영해야 함에도 불구하고, 현재 대다수의 도시공원이 환경특성을 반영하지 못하고 일률적으로 조성되어 유지되고 있다. 이에 본 연구에서는 2005년 공원법 개정 후, 세분유형 변경이 완료된 공원을 중심으로 변화를 살펴보았다. 법적공원유형이 변경된 공원은 모두 45개로 그중 어린이공원에서 소공원으로 유형변경이 21개소로 가장 많았으며, 주제 공원인 문화공원과 역사공원으로 공원의 특성을 살리고자 하는 경우도 19개소에 달했다. 변경 유형별로 문화공원과 역사공원은 건물 신축 등 시설율이 증가한 반면, 소공원은 시설면적이 감소하고 녹지면적이 증가하였다. 공원시설면적 증감을 분석한 결과, 공원 정비를 통한 이용활성화를 추구하는 긍정적인 효과와 동시에 녹지면적이 감소하는 부정적인 면을 확인할 수 있었다. 도시에서 공원이 가지는 순기능 중 하나인 생태환경 유지를 위해서는 공원 주변여건에 대한 반영과 함께 새로운 시설기준 마련이 필요하다. 추후 공원 유형별 시설기준에 대한 심도 있는 논의를 통해 도시공원 유형별 조성 가이드라인 마련을 위한 심층적인 연구가 진행되기를 기대한다.

The purpose of this study is to investigate the desirable method of courtesy education for middle school students. The major research questions of this study are to identify and test the follows： 1) The influence of the environment (grade, sex, the educational background of father, the educational background of mother, the scale of family, the presence of grandfather, the presence of grandmother, students’age ranking among their brothers and sisters, religion, academie record) on the middle school students’ knowledge and attitude on courtesy. 2) The influence of the courtesy education on students’knowledge and attitudes on courtesy. 3) The degree of change on their knowledge and attitudes after courtesy education. The response were given by 485 middle school students and their mothers in Wanju county Chonbuk province. Frequences, Percentages, Means and Standard Deviations were calculated, T-test and Pearson Correlation Coefficients were used for data analysis. The result of this study are as follows, 1. The influence of environment： 1) Higher grade students gained more score of courtesy test than lower grade ones. 2) Female students gained more score than male students. 3) The students who had higher academic record gained more score of courtesy test than any other students. 2. The influence of courtesy education： Most of educated groups changed significantly due to courtesy education. It showed that courtesy education contributed to improve their knowledge and attitudes on courtesy. 3. After courtesy education： On the one hand, the most changed attitude was bow-courtesy area and then good-manners area, conversation-courtesy area, etc. On the other hand, the basic spirit area on courtesy changed less than any other areas. It means that long-term courtesy education should be done in order to change students’ attitudes on courtesy basically, even though they could improve their knowledge and attitudes externally in a short time.

Until 1960, the major housing type of rural area in Korea was traditional wooden frame building, which was made of natural materials. In the course of modernization and New Village Movement, most of traditional houses have been renovated focusing on changing roof material of rice straw into slate, keeping existing main wooden structure. And then from around 1980, by economical development the new houses have been constructed. On these three phases of traditional type, remodeling type and new construction type, the natural materials of housing facade as wood, soil, stone and plant changed into artificial materials as cement, chemical material and paint. At the same time the exterior color of housing also have been changed and varied. The purpose of this thesis is to find out the changing aspect of exterior color by comparing remodeled and new constructed housing with of traditional housing. The exterior color of one hundred and fifty seven houses were surveyed and the three color attributes of each part of facade, as roof, wall and window, were analyzed and compared. In case of traditional houses, 98.3% of color are concentrated on the warm color of Y and YR on HUE scale, and 88% of their color are low Chroma. And Value of their color has been varied and spreaded from low to high Value scale. From traditional types to remodeled and new constructed houses, the concentration ratio of warm color on Hue scale reduced from 98.3% to 68.7% and ratio of low Chroma was also changed from 88% to 73.2% and the ratio of low Value color reduced from 51.9% to 29.7%. The exterior color of houses in rural area varied on Hue, and the more saturated colors were used and they became brighter compared with color of traditional houses. It is expected that the results of this study can be used for basic data of exterior color planning and improvement into harmonized color with natural environment.

지각 천부인 취성변형의 조건 하에서도 지표에서 발달하는 절리들의 방향성 분포가 지하 심부로 가면서 지하 몇 미터에서부터 불연속면의 변화를 보이는지에 대해 의문이 생긴다. 이에 대한 의문의 해결을 위해 본 연구에서는 지표지질조사를 통해 측정한 불연속면의 자료와 BIPS 및 Televiewer에 의해 측정된 불연속면의 자료들을 두 개 지역에 대해 비교 분석하였다. 호남탄전지역은 지하 심부로 가면서 지표에서 30 m와 40 m 지점에서 불연속면의 방향성이 변하며 수원지역의 경우는 20 m에서 불연속면의 방향들이 변화하였다. 이와 같은 변화가 등방성의 암석에서 변화를 관찰함이 심도별 변화를 대비 할 수 있으나 호남탄전의 경우는 퇴적암으로 측정된 암반이 세립질의 사암과 세일이 교호하는 이방성의 암반이며 스르스트단층이 통과하고 있다. 그러나 수원지역의 경우는 대개 운모편암들로 호남탄전 지역보다는 암질의 변화가 적다. 그러나 두 지역 공히 지하 20 m와 30 m 이하에서 이미 지표와는 달리 불연속면의 분포특성이 바뀜을 시사하고 있다.

In many plant cells, the positions of chloroplasts change in response to changes in light conditions. In the epidermal cells of the aquatic angiosperm Vallisneria gigantea, the avoidance response of chloroplasts is induced specifically by irradiation with blue light of high intensity. Possible roles of actin cytoskeleton in the blue-light-induced avoidance response of chloroplasts were investigated by partial irradiation and phalloidin staining. We showed that the blue-light-dependent redistribution of chloroplasts was induced only in the limited area, where exposed to blue light, even in individual cells. In addition. in the exposed area, the configuration of actin filaments strikingly changed compared with that before the irradiation. Short and thick bundles of actin filaments surrounding the chloroplasts changed to much longer and thinner bundles with a more stretched array. In contrast, in the unexposed area, neither the distribution of chloroplasts nor the configuration of actin filaments exhibited any changes. Cytochalasin D and latrunculin B inhibited the avoidance response of chloroplasts concomitantly with the fragmentation of actin filaments. These results indicate that the reorganization of actin filaments plays a crucial role in the induction of avoidance response of chloroplasts.

Most of precedent studies related to hip hop culture and fashion, which have been conducted till now were progressed under only theoretical background of hiphop, not the changed status of hiphop currently. Practical studies explaining the status of hip hop in popular culture, especially, the area of popular fashion are insufficient. Therefore, this study was conducted by focusing on cultural characteristics and musical characteristics by the stream of period, for which concept hip hop is accepted to people currently and which effect it makes on the area of fashion. Especially, the study was progressed by dividing periodical background into before and after the 2000s because there was the most noticeable change for the genre of hip hop in that period. Because of the appearance of 'Alternative hip hop' which is a sub-genre of hip hop music, hip hop music was changed to be more popular. Also, hip hop fashion also showed big changes. Hip hop fashion before 2000s had showed poor conditions, resistance, complex and alienation of them by their fashion. On the other hand, hip hop fashion after 2000s also showed popular characteristics because of high-level environment and social status. This study intended to understand and grasp hip hop as a kind of cultural situation coexisted by many-sided characteristics as well as redefine the changed concept and contents of new hip hop currently.
