Ch'ang-Ts'al-Ts'un is a rural Village near Lung-jing City in Yen-pien Korean Autonomous Province of China. It was formed about 100 years ago by Korean Immigrants and has been developed maintaing the characteristics of traditional Korean architecture. Therefore investigating the spatial structure of this village is a meanigful work to confirm and explore one branch of Korean architecture. This study aims at analyzing the spatial structure of the village using direct data collected from the field work and indirect data from books and maps. The field work consists of on-the-site survey of the village layout, interviews of residents, observation notes and photography. Ch'ang-Ts'ai-Ts'un is located 360-370 m high above the sea level and at the side of a long valley. A river flows in the middle of the valley and relatively flat arable land exists at the both sides of the river. The location of the village related to the surrounding river and mountains suggests that the site of the village was chosen according to Feng-Shui, Chinese and Korean traditional architectural theory. The main direction of the house layouts is South-western. The village has been growing gradually until today. Therefore it is meaningful to make the village layout before Liberation(1946 A.D.) because the characteristics of Korean architecture prevailed more in that period. The area of the previous village is limited to the west side of the creek. New houses were later added to the east of the creek, forming a 'New Village'. Previously the village was composed of 3 small villages: Up, Middle and Down. Also the main access roads connecting the village with the neighboring villages were penetrating the village transversely. Presently the main access road comes to the village longitudinally from the main highway located in front of the village. The retrospective layout shows the existence of well-formed Territory, Places and Axes, thus suggesting a coherent Micro-cosmos. The boundary of imaginery territory perceived by present residents could be defined by linking conspicous outside places sorrounding the village such as Five-mountains, Front-mountain, Shin-dong village, Standing-rock, Rear-mountain and Myong-dong village. Inside the territory there are also the important places such as Bus-stop, Memorial tower of patriots, Road-maitenance building and the village itself. And inside it 5 transverse and 1 longitudinal axes exist in the form of river, roads and mountains. The perceived spatial structure of the village formed by Places, Axes and Territory is geometrical and well-balanced and suggests this village is fit for human settlement. The administrative area of the village is about 738 ha, 27 % of which is cultivated land and the rest is mountain area. Initially the village and surrounndings were covered with natural forest But the trees have been gradually cut down for building and warning houses, resulting in the present barren and artificial landscape with bare mountains and cultivated land. At present the area of the village occupied by houses is wedge-shaped, 600 m wide and 220 m deep in its maximum. The total area of the village is $122,175m^{2}$. The area and the rate of each sub-division arc as follow. 116 house-lots $91,465m^{2}$ (74.9 %) Land for public buildings and shops $2,980m^{2}$ (2.4 %) Roads $17,106m^{2}$ (14.0 %) Creek $1,356m^{2}$ (1.1 %) Vacant spaces and others $9,268m^{2}$ (7.6 %) TOTAL $122,175m^{2}$ (100.0 %) Each lot is fenced around with vertical wooden pannels 1.5-1.8 m high and each house is located to the backside of the lot. The open space of a lot is sub-divided into three areas using the same wooden fence: Front yard, Back yard and Access area. Front and back yards are generally used for crop-cultivation, the custom of which is rare in Korea. The number of lots is 116 and the average size of area is $694.7m^{2}$. Outdoor spaces in the village such as roads, vacant spaces, front yard of the cultural hall, front yard of shops and spacse around the creek are good 'behavioral settings' frequently used by residents for play, chatting, drinking and movie-watching. The road system of the village is net-shaped, having T-junctions in intersections. The road could be graded to 4 categories according to their functions: Access roads, Inner trunk roads, Connecting roads and Culs-de-sac. The total length of the road inside the village is 3,709 m and the average width is 4.6 m. The main direction of the road in the village is NNE-SSE and ESE-WNW, crossing with right angles. Conclusively, the spatial structure of Ch'ang-Ts'ai-Ts'un village consists of various components in different dimensions and these components form a coherent structure in each dimension. Therefore the village has a proper spatial structure meaningful and appropriate for human living.

Focus has been put on current status of research in the aspect of heating, cooling, air-conditioning, ventilation, sanitation and building environment. The conclusions are as follows. (1) Most of fundamental studies on fluid flow were related with heat transportation of facilities. Drop formation and rivulet flow on solid surfaces were interesting topics related with condensation augmentation. Research on micro environment considering flow, heat, humidity was also interesting for comfortable living environment. It can be extended considering biological aspects. Development of fans and blowers of high performance and low noise were continuing topics. Well developed CFD and flow visualization(PIV, PTV and LDV methods) technologies were widely applied for developing facilities and their systems. (2) The research trends of the previous two yews are surveyed as groups of natural convection, forced convection, electronic cooling, heat transfer enhancement, frosting and defrosting, thermal properties, etc. New research topics introduced include natural convection heat transfer enhancement using nanofluid, supercritical cooling performance or oil miscibility of $CO_2$, enthalpy heat exchanger for heat recovery, heat transfer enhancement in a plate heat exchanger using fluid resonance. (3) The literature for the last two years($2004{\sim}2005$) is reviewed in the areas of heat pump, ice and water storage, cycle analysis and reused energy including geothermal, solar and unused energy). The research on cycle analysis and experiments for $CO_2$ was extensively carried out to replace the Ozone depleting and global warming refrigerants such as HFC and HCFC refrigerants. From the year of 2005, the Gas Engine Heat Pump(GHP) has been paid attention from the viewpoint of the gas cooling application. The heat pipe was focused on the performance improvement by the parametric analysis and the heat recovery applications. The storage systems were studied on the performance enhancement of the storage tank and cost analysis for heating and cooling applications. In the area of unused energy, the hybrid systems were extensively introduced and the life cycle cost analysis(LCCA) for the unused energy systems was also intensively carried out. (4) Recent studies of various refrigeration and air-conditioning systems have focused on the system performance and efficiency enhancement. Heat transfer characteristics during evaporation and condensation are investigated for several tube shapes and of alternative refrigerants including carbon dioxide. Efficiency of various compressors and expansion devices are also dealt with for better modeling and, in particular, performance improvement. Thermoelectric module and cooling systems are analyzed theoretically and experimentally.

This thesis purports to overview the diverse administrative and organizational factors and plannings developed by the government organizations, municipal or otherwise, to tackle the Han River water pollution issues in the past years. This thesis also looks into the ever-worsening Han River water pollution problems, in particular, in terms of the various government plans ostensibly designed to reduce the pollution level but with little success. Also dealt with are the efficiencies with which the laws and decrees on water pollution the administrative organizations put to use in the prosecution of the diverse antiwater pollution projects involving the Han River basin. From the early 1960's up to the 1970's the government had concentrated on the growth-oriented economic policy with the result that little attention had been paid to the water pollution and other environmental issues that are bound to arise from the massive economic growth. Belatedly, the five-year Hah River Development Project was initiated in 1982 with emphasis on reducing the water pollution level at Hah River to the minimum. The following are the gists of the thesis and recommendations for the future antiwater pollution plans by the administrative organizations: 1. Documents to date indicate that the irrigation projects along the Han River area had been the main focus of attention during the Yi Dynasty and under the Japanese rule of the country. 2. Despite that the water pollution issue became the subject of many debates among the academic and research institutions in the 1960's and in the 1970's, the administrative organizations in charge of the Han River water quality control failed to come up with a concrete plan for the river's water quality control. 3. Nevertheless, the water pollution of the Han River area in fact began in the 1950's, with the unprecedented concentration into Seoul of population and the industrial facilities on a larger scale, in particular, enforced by the government's strong growthoriented policy in its Economic Development plans in the 1960's. 4. Starting in the 1960's, the Han River water pollution level dramatically increased, but the government was reluctant to promulgate or put into effect strong measures to curb the many factors contributing to the river water pollution, thus worsening the environmental issues along the Han River basin. 5. The environmental protection law and other laws and decrees relating to the antiwater and air pollution issues that were subsequently put into effect underwent so many changes that efficient anti-water pollution policies could not be effected for the Han River basin. The frequent organizational reshuffle within the administrative units concerned with environmental problems has resulted in the undue waste in personnel management and finance. 6. The administration on the environmental protection could not be efficiently carried out due to the organizational overlapping. Under the existing law, frequent organizational frictions and inefficiency are bound to occur among the central government offices themselves, as well as between the central government and the Seoul city administration, and among the city's administrative offices over the conservation of the Han River basin and over the river's anti-water pollution issue. 7. In the planning and prosecution of the Han River project, political influences from the president down to the lower-level politicious appear to have been involved. These political influences in the past had certainly had negative influence on the project, nevertheless, it appears that in the recent years, these political influences are not all that negative in view of the fact that they serve as a positive contributing factor in developing a better water quality control project along the Han River basin. The following are a few recommendations based on the data from the thesis: First, officials in charge of the Han River water quality control should pay attention to a careful screening of the opinions and recommendations from the academic circles and from the public should be made so that the government could better grasp the core issues in the environmental problems that require preventive and other necessary measures. Second, vigorous redistribution policies of population and industrial facilities away from the Seoul area should be pursued. Third, the government should refrain from revising or revamping too frequently the laws and decrees on the anti-water pollution, which is feared to cause undue inconveniences in the environmental administration. Fourth, a large-scale streamlining should be made to the existing administrative organization in an effort to do away with the inter- and intra-organizational friction. It is recommended that a secretariat for the Hah River basis conservation be established. Fifth, High-level administrative officials, with a thorough knowledge and vision on the Han River water quality control, should be prepared to better deal with the budgeting and personnel management for the Han River water pollution control not only at the control government, but also at the Seoul city municipal government levels. Environmental issues should be kept distinct from political issues. Environmental issues should not serve as a window-dressing for sheer political purposes. Sixth, the Hah River proiect should also include, along with the main Han River basin, those areas covering North Han River, South Han River, and the tributaries to the main river basin. The 'Han River Basin Water Quality Control Board' should be established immediately as a means of strengthening the current Han River basin water quality control policy. Seventh, in drawing up the Han River proiect, the administrative officials should be aware that Han River basin is a life line for those people in the region, providing them with not only a sheer physical space, but with a psychological living space for their everyday life.

조선 시대의 재지사족은 핵심적인 지배집단이었다. 그들은 전국적으로 분포한 중소 규모의 지주였으며, 유교적 소양을 보유한 지식인 집단이었다. 17세기 이후로는 곳곳에 동성마을을 형성하고, 현조(顯祖)를 내세우면서 지역 사회에 대한 영향력을 행사했다. 그 결과 지역에서의 실질적 주도권을 재지사족이 행사하는 예가 많았다. 이런 면에서 제천 지역의 황강(黃江) 신동(新洞)에 정착한 안동 권씨 화천군파(花川君派) 문중은 대표적인 재지사족이었다. 이 집단은 1675년에 이뤄진 권상하 형제가 이주하면서 형성되었다. 노론 정파의 지도자였던 송시열의 수제자인 권상하는 과거를 외면하고 황강에서 강학에 힘썼으며, 결국은 산림(山林)으로 초빙되어 좌의정으로 제수되기까지 하였다. 권상하의 사후에 그가 가르치던 곳에는 황강서원을 비롯한 기념 시설과 제사 공간이 설치되었다. 이러한 시설들은 권상하가 중시했던 삶의 가치를 후손들이 받아들이는데 이바지했고, 지역 사회에 숭명의리(崇明義理)에 토대를 둔 척사적(斥邪的)인 정서가 자리 잡도록 하는데 이바지했다. 화천군파가 제천 지역에서 재지사족으로 성장하는 과정에 결정적인 역할을 한 인물은 또 다른 인물은 권상하의 조카인 권섭(權燮)이었다. 그는 권상하를 위한 여러 기념시설을 건립하고, 문중의 발전을 위하여 여러 규칙을 제정하였다. 아울러 황강을 넘어서 제천의 신동에 새로운 거주공간을 확보하고, 청풍 단양 문경 등지에 별서(別墅)를 장만하며 거주공간을 넓혀 나갔다. 각각의 공간에는 조상을 모시기 위한 제사 시설도 설치했다. 그 결과 권상하와 권섭의 자손들은 제천 일대에서 대표적인 성씨 집단으로 수백 년간 위세를 누릴 수 있었다. 비록 그들은 서울에 남았던 이들에 비하여 많은 엘리트 관료를 배출할 수는 없었다. 그러나 이러한 재지사족의 성장은 지역 사회의 문화적 성장, 나아가 전 조선 사회의 발전을 가능하게 했다.

This study aimed at developing a desirable family planning policy and strategy by examining the current status of family planning practice in rural Korea and by indentifying the crucial factors which affect fertility control behavior. For this purpose, an analytical study was conducted, using the survey data collected in July 1985, on an interview basis, on 1, 440 married women living in the Soyi, Wonnam and Maingdong townships of Eumseong County(in North Chungcheong Province). This study population has the typical characteristics of rural areas, and the results of the analysis can be summarized as follows: 1. In regard to the demographic characteristics of the study population : their average age at marriage was 23.7, they had an average of 2.6 children( 1.3 boys, 1.3 girls) :10% experienced the death of their child (ren) :14% had spontaneous abortion(s) :4% weathered stillbirth(s) :35% went through induced abortion (s) : and 5.5% were currently pregnant. The average of their ideal numbers of children was 2.2, while 44% felt that they must have a son. 2. Looking at the contact rate with medical & health institutions, over the past 1 year, the visit rate to health subcenters was 43.7%, while 26.9% visited the (county) health center :59.6% had been to private clinics : and 41.5% went to the Soonchunhyang - Eumsung hospital : thus showing a relatively high rate of accessibility. 3. The utilization rate of family planning services was 76.5%, with tubectomy being the most prominent method at 52.3%, while the informants were health workers in 54.2% of the acceptors. Of the 8.4% who discontinued the use of contraceptive methods, only 26% did so due to want for pregnancy, natural infertility (meno - pause), or other reasons, while the remaining 74% stopped usage on account of side effects, failure in the methods themselves, and inconvenience of use, thus pointing to a situation where the proper choice of family planning methods have not yet been made. It can be noted that there is a strong motivation for early birth stopping as 35.3% practice family planning even with only one child, of which 38.3% have had sterilization operations. According to results of a multiple regression analysis, among the variables affecting contraception usage the most significant variable was the number of sons. 4. 34.8% experienced induced abortions. It was shown as a result of multiple regression analysis that the number of children and attitudes toward induced abortions extensively affected their frequency of abortions conducted. 5. In the regard to the relation between family planning and induced abortions, 33.7% of the women used both, while 52.0% of them used only the former(family planning), with only 1.4 % utilizing solely the latter(abortion), and 12.9% totally abstaining from fertility regulation : again, the discriminant analysis indicated that the choice of family planning and/or induced abortion was determined by the number of children and attitudes toward induced abortion. In view of the above mentioned results, the following are some comments and suggestions concerning problems related to the current family planning policies, in Korea : 1. It is difficult to expect a further quantitative expansion in family planning program operations, as there has been an excessive supply of target-oriented sterilization operations on women. From a maternal and child health care point of view, it will be desirable to have a diversification of service points in the future where family planning methods may be properly chosen, so that choices of methods which suit the mothers' characteristics and tastes may be made by the individuals themselves by strengthening their quality of family planning information services. 2. Along with the strengthening of the qualitative improvement of family planning services policies must be implemented to effectively promote the moral (ethical) deterrents to induced abortions and to preference for sons. From a maternal care standpoint, the social permissive norm toward induced abortion must be modified, and the bias towards son must be analyzed as the women with more daughters have a lower rate of family planning acceptance. Such changes in attitudes, however, can not be hoped to be accomplished with ad hoc policies, but will only be possible when an enhancement of the women's status(within the society) is brought about in a long - term perspective.

본 연구는 국내 서식하는 아메리카동애등애(BSF)의 생태특성 구명 및 가축분뇨를 이용한 BSF의 실내 인공사육을 통하여 가축분뇨나 음식물쓰레기 처리 시 대량으로 요구되는 유충생산을 위하여 실내 인공증식기술 개발하고 BSF의 가축분뇨 분해 능력을 검정하였다. BSF는 축사를 중심으로 하는 즉 유기성 폐기물이 야적되어 있는 장소의 생태계 내에서 서식한다는 것을 확인하였으며, 축사, 퇴비사, 생활쓰레기장, 음식물쓰레기장 주변이 주 서식지임을 확인하였다. 가축분뇨 분해 우수 종은 BSF(Hermetia illucens), 동에등에(Ptecticus tenebrifer) 등 2종으로 확인되었다. 가축분뇨에 따른 BSF의 분해능은 BSF 유충 마리당 돈분 0.5 g, 우분 0.43 g, 계분 0.3 g순으로 돈분이 가장 우수하였다. 가축분뇨별 BSF 유충의 분해에 따른 무게는 우분 83.62, 돈분 77, 계분 80%로 우분이 분해 후 무게 감소가 가장 컸다. 가축분뇨 분해에 따른 BSF 유충 및 번데기 형질은 돈분이나 돈분 +왕겨를 혼합하여 처리했을 때 유충이나 번데기의 길이, 무게 폭이 다른 처리구에 비해 좋았다. BSF 실내 대량증식에 있어서 용화율 및 우화율에는 큰 차이를 보이지 않았으나 교미 산란에 있어서 중요한 요소인 광조건 변화에 의한 계절적 교미율의 차이를 보였다. 계절에 따른 BSF의 교미율을 보면 5월에서 7월까지 교미가 활발하게 이루어 졌으며, 시간대는 오전 10시부터 12시까지 가장 활발하게 교미를 하였다. 인공채란을 위한 산란배지는 음식물과 송아지 사료가 가장 우수하였고, 산란실($W{\times}D{\times}H=4{\times}2{\times}2m$) 내 적정 배지투입 수는 8개, 성충은 2000두 투입구가 가장 산란효율이 높았다. 산란유도재료로 플라워폼과 목재에 구멍을 뚫어 산란을 유도하였으며, 산란장소의 구멍크기는 3~5 mm, 깊이 7~10 mm의 크기를 가장 선호하였다. 유충은 2~4두/$cm^2$의 밀도로 사육하는 것이 과밀도(6~10두/$cm^2$) 보다 실용형질이 우수하였다. 번데기 적정보호조건은 매질(톱밥)을 사용하여 은신처를 제공해야하며, 톱밥의 습도는 20~40%가 가장 좋았다. 성충은 우화 즉시 사용해야하나, 용화 후 10에서 10일 처리한 경우 우화율 93.3%로 우화시기를 약 10일 정도 조절이 가능하였다.

최근 보육교사가 수행하는 업무의 다중성 및 법적 신분과 관련된 쟁점이 부각되고 있다. 보육교사는 "근로기준법"상의 근로자이면서, "영유아보육법"상의 보육교직원이고, 누리과정 실시로 인해 "유아교육법"상의 유치원 교사의 업무도 수행한다. 영유아를 보호하고 양육하는 보육교사의 주업무를 기본으로 유아를 대상으로는 누리과정을 통한 교육프로그램을 진행하는 것이다. 하지만 보육교사의 직업적 의무가 법적인 권리와 부합되지 않는 부분이 있어 보육교사의 권리와 의무는 불균형적인 상황에 놓여 있게 된다. 본 연구는 해석주의 인식론에 기반한 질적방법을 활용하여 보육교사들이 현장의 경험을 통해 자신의 권리를 어떻게 인식하는지를 실증적으로 고찰하였다. 연구참여자는 수도권에 근무하는 보육교사 61명이며, 자료수집을 위해 프로토콜(protocol) 서술과 포커스그룹면접(FGI: focus group interview)을 활용하였다. 수집된 자료는 Creswell(2013)이 제안한 자료분석법에 따라 중심주제로 도출되었다. 연구결과를 보면, 보육교사들은 전문직으로서 교육권과 자율권, 근무여건 개선 및 복지후생 요구권, 고충처리 및 신분보장권에 대한 경험적 인식을 구체적으로 진술하였다. 보육교사들은 어린이집의 열악한 근무여건 및 복지후생을 지적하는 동시에 교육권과 자율권이 양질의 보육활동을 위해 강화되어야할 필요조건임을 강조하였다. 한편, 연구참여자들은 고충처리 및 신분보장권이 자신의 권리라는 점에 대한 인식 자체가 낮았고, 해당 권리의 침해를 감수하는 경향을 보였다. 본 연구결과는 보육교사들의 의무와 권리 사이의 간극을 드러내면서 이에 대한 제도적 마련이 필요함을 보여준다. 영유아 전문가로서 인성 및 전문성 강화에 대한 사회적 기대가 높아짐과 동시에 근로에 대한 사회적 가치관의 변화를 고려하여, 보육 현장에 근무하는 교사의 권리 향상을 위한 실천적 대안이 필요하다는 점을 논의하였다.
