Since the first year economic development plan, imblanced development of national territory during the economic development process has aggravated remarkable disparity between urban and rural areas. For this reason, this study introduced the development of rural market as one of the development strategies of regional economic to correct the imblance and relieve regional disparity. The purpose of this study were to look into the present situation of traditional rural market and to analyze the problems for the rural development in view of the current road situations in the rural areas and status of marketing facilities in market center and to measure the degree of rural area people's satisfaction to the rural market and to suggest the development plan of activating for rural market center. To collect data, the Yesan Gun rural market were selected and a total of 591 residents and 178 merchants were sampled as final subjects of survey. Interview and/or questionnaire method was the main method of data collection. The major findings of this study were as follows: 1) The population of Yesan Gun has decreased 2.85 persons per year from in 1984, but the number of vehicles were increased 2.85 times than in 1989. And the parking capacity of Yesan Eup was only 129 vehicles which were below of the total vehicles of Yesan Gun area (14,352). The number of Yesan area markets were 8 markets which consisted of 1 permanent market and 7 periodic markets. But as the economy has been developed, the conditions of rural markets have been changing. That is, the role of periodic market tends to be weakened with the growth of large cities, reinforcement of permanent markets, development of traffic facilities, large production, preferring high quality goods. 3) Generally, the people of Yesan Gun were attached for purchasing the necessaries of life and comodities and farming materials to ① Yesan Eup ② Seoul ③ Chonan Shi ④ Hongsung gun ⑤ Daejeon Shi. 4) The degree of community people's satisfaction to the town market presented 26.6% which meaned higher than dissatisfaction(9.5%). And the degree of people's inconvenience of accessibility to market center by transferring of bus terminal presented 64.2% which meaned higher than average. 5) The degree of people's dissatisfaction of traffic system in Yesan gun area presented followings: the road networks(61.5%), parking facility(68%), bus route(54%). 6) By the survey of merchants of Yesan gun area, on the average, it showed followings: the size of store was 6-10 pyeong(40%), the type of enterprise was retail dealer(70.9%), and purchasing place was wholesale dealer from Seoul(51.8%). 7) And they thought that Yesan town market were too small(70.8%), and the diversifying of goods was not enough(35.5%). 8) The merchants of Yesan area showed that the degree of into venience to traffic system was 72.7% and its to parking facility was 83.3%. And they complained that community administration agency have not tried to activate market(79.1%). Based on the results of this study, the following recommendation were made for activating regional economy and community market. That is, it is to strengthen the economic function in community market so as to suffice the economic and social activities for settlement area as their living space. And it is necessary to improve the interrelationship of the central functions. 1) So, the accessibility between market center and its surrounding areas must be rised. ① the enforcing preferentially to pave the bus terminal and market center to link two place. ② the running of shuttle-bus two place every regular market day. ③ the widening and connecting the road to rise accessibility between market center and its surrounding area. ④ the enforcement of parking facility around market center. ⑤ the constructing marketing centered area as intergrated body of various marketing facilities in the adjacent site is the centered area planned to achieve efficient marketing. 2) The modernization and specialization market center facilities. 3) The strengthening of drawing surrounding area people into Yesan market center. So, the following recommended: ① the development of special products market ② inducing special projects ③ the development tour and leisure course drawing industrial facilities. 4) And it needs to enforce community people's local patriotism and to support community markets by administration agency.

AgInS₂단결정 박막은 수평 전기로에서 합성한 AgInS₂다결정을 증발원으로하여, hot wall epitaxy(HWE) 방법으로 증발원과 기판(반절연성-GaAs(100))의 온도를 각각 680℃, 410℃로 고정하여 단결정 박막을 성장하였다. 이때 단결정 박막의 결정성은 광발광 스펙트럼과 이중결정 X-선 요동곡선(DCRC)으로부터 구하였다. Hall 효과는 van der Pauw 방법에 의해 측정되었으며, 293K에서 운반자 농도와 이동도는 각각 9.35×10^(16)/㎤, 294 ㎠/V·s였다. 또한 광흡수 spectra에서 energy band gap의 온도 의존성 E_(g)(T)는 2.3165eV-(9.89×10_(-3)eV/K)T² / (T+2930K)임을 확인하였다. 성장된 AgInS₂단결정 박막을 Ag, S, In 분위기에 열처리하여 10K에서 photoluminescience(PL) spectra를 측정하여 점 결함의 기원을 알아보았다. PL 측정으로부터 얻어진 V_(Ag), Vs, Ag_(int), 그리고 S_(int)는 주개와 받개로 분류되어졌다. AgInS₂단결정 박막을 S분위기에서 열처리하면 p형으로 변환됨을 알 수 있었고, In 분위기에서 열처리하면 열처리 이전의 PL spectra를 보이고 있어서 I₂, I₁ 및 S, A emission에 의한 PL peak에는 영향을 주지 않는다고 보았다. A stoichiometric mixture of evaporating materials for AgInS₂single crystal thin films was prepared from horizontal furnace. To obtain the single crystal thin films, AgInS₂ mixed crystal was deposited on thoroughly etched semi-insulating GaAs(100) substrate by the Hot Wall Epitaxy(HWE) system. Temperature of the source and substrate were 680℃ and 410℃, respectively. The crystalline structure of the single crystal thin films was investigated by the photoluminescence and double crystal X-ray diffraction (DCXD). The carrier density and mobility of AgInS₂single crystal thin films measured from Hall effect by van der Pauw method are 9.35×10^(16)cm^(-3) and 294 cm²/V·s at 293 K, respectively. From the optical absorption measurement, the temperature dependence of the energy band gap bn-AgInSz single crystal thin films was found to be E_(g)(T) = 2.1365 eV - (9.89 x10^(-3) eV) T²/(2930 + T). After the as-grown AgInS₂single crystal thin films was annealed in Ag-, S-, and In-atmospheres, the origin of point defects of AgInS₂single crystal thin films has been investigated by using the photoluminescence(PL) at 10 K. The native defects of V_(Ag), Vs, Ag_(int), and S_(int) obtained from PL measurements were classified as a donors or acceptors type. And we concluded that the heat-treatment in the S-atmosphere converted AgInS₂single crystal thin films to an optical p-type. Also, we confirmed that In in AgInS₂/GaAs did not form the native defects because In in AgInS₂single crystal thin films did exist in the form of stable bonds.

본 연구에서는 2차원 NACA 0024 에어포일에서 앞전 슬릿흡입과 riblets이 경계층 구조에 미치는 영향에 대하여 실험적으로 고찰 하였다. 슬릿흡입(slit suction)에서 슬릿의 위치와 수, 자유흐름속도, 받음각 그리고 슬릿 흡입량이 중요한 변수이다. 슬릿흡입과 리블렛(riblets)이 설치된 2차원 에어포일의 양력계수와 항력계수 실험결과를 제시하였다. 에어포일에 슬릿 흡입을 적용하면 양력계수 항력계수가 다같이 증가된다. 원형 리블렛이 설치된 에어포일 모델에서는 양력계수가 증가되고 항력계수가 감소된다. An exprimental study on manipulation of the boundary layer of the two-dimensional NACA 0024 airfoil with slit suctions and riblets is presented. The slit locations, the number of slits, free stream velocity, angle of attack and the suction rate coefficient are variables. Exprimental results for the lift and drag coefficients of the two-dimensional airfoil with slit suctions and riblets are presented. When the slit suction is applied on the airfoil wall the lift and drag coefficients increase. Airfoil model with round riblets on the wall shows an increase of the lift coefficients and a decrease of the drag coefficient.
