전창진,이재현,이창헌,Jeon, Chang-Jin,Lee, Jae-Hyun,Lee, Chang-Eon Korean Society of Electron Microscopy 1986 Applied microscopy Vol.16 No.2

자라의 위 및 십이지장에 출현하는 내분비세포의 형태를 알아보기 위하여 전자현미경으로 관찰을 행하였던 바, 과립의 크기, 형태, 전자밀도 및 세포의 형태 등에 의해 다음과 같이 6종의 세포형으로 구분할 수 있었다. I형 : 직경 $100{\sim}430nm$(평균 290nm)로서 전자밀도가 낮고 많은 수의 다양한 형태의 과립을 가진 것. II형 : 직경 $190{\sim}430nm$(평균 280nm)로서 높은 전자밀도를 나타내며 다양한 형태의 과립을 가진 것, III형 : 직경 $170{\sim}650nm$(평균 430nm)로서 전자밀도가 높고 과립막과 내용물 사이에 넓은 halo를 형성하는 과립을 가진 것. IV형 : 직경 $140{\sim}370nm$(평균 240nm)로서 전자밀도가 대체로 낮고 과립막과 내용물이 밀착된 과립을 가진 깃. V형 : 직경 $300{\sim}600nm$(평균 410nm)로서 전자밀도는 낮거나 중등도이며, 과립은 곽립막과 내용물 사이에 명확한 halo를 형성하고, 세포질내 미세섬유를 가지는 것. VI형 : 직경 $100{\sim}220nm$(평균 160nm)로서 대체로 소형의 과립을 가지며, 전자밀도는 다양하고 과립은 과립막과 내용물 사이에 halo를 형성하는 것, 밀착된 것 또는 내용물이 결정구조를 나타내는 것 등으로 다양하며 세포질내 풍부한 미세섬유를 가지는 것. The endocrine cells of the stomach and duodenum of the pond tortoise (Amyda sinensis) have been studied by electron microscopy. At least six types of endocrine cells could be identified in these regions. Type I cells were characterized by having pleomorphic or medium sized granules ($100{\sim}430nm$ in diameter, mean; 290 nm) which were moderate in electron density. Type II cells were characterized by having pleomorphic or medium sized granules ($190{\sim}430nm$ in diameter, mean; 280 nm) which were high in electron density. Type III cells were characterized by having large oval or irregular granules($170{\sim}650nm$, mean: 430 nm) with wide vesicular halo which were high in electron density. Type IV cells were characterized by having round or medium sized granules($140{\sim}370nm$, mean; 240 nm) which were low to moderate in electron density and showed a very thin halo. Type V cells were characterized by having large round or oval granules($300{\sim}600nm$, mean; 410 nm) which were low to moderate in electron density and showed a dense core and a wide clear halo. Microfilaments were also found in the cytoplasm. Type VI cells were characterized by having round and small granules($100{\sim}220nm$, mean; 160 nm) which were low to moderate in electron density and showed a very thin halo or crystalline structure of the contents. Many microfilament bundles were also found in the cytoplasm.

도시에 있어서 인구집중 및 산업의 집중으로의 도시문제 발생은 세계적인 경향으로서 모든 국가와 도시에 있어서 그 대책을 고민하고 있다. 특히 세계에서도 보기 드문 도시화의 진행에 있어 도시의 무질서한 확대와 기반시설의 정비가 심각한 문제로 제기 되고 있다. 국토의 가장 중요한 부분으로 도시지역이 결정적인 변용을 하려고 하는 때에 도시계획의 적정화와 그 규제의 강화, 도시계획시설의 계획적, 중점적 정비가 중요한 중심에 놓여 있다. Most of the cities and countries have distressed themselves about the urban social problem caused by the concentration of industry and population. Especially, disorderly expansion of cities and infrastructure improvement in rapid urbanization have also come into question. For this reason, proven urban planning facilities and tightened regulation on city planning are indispensible to solve these serious problems that we face. There are lots of similar studies to verify how to cope with a rapid urbanization.

Existing urban improvement projects were carried out with focus on the physical maintenance led by the government, which resulted in the problems such as dissolution of the community and removal of space for the underprivileged. In recent years, however, the Urban Renewal Agency of the Korea Land and Housing Corporation (LH) carried out a pilot project for urban regeneration at a regional level to implement urban regeneration policies considering physical and socio-economic regeneration. The project was promoted by a bottom-up development approach that establishes local governance through the participation of local residents and each subject. In addition, the strengthening of local capability is considered to be most important in the promotion of sustainable urban regeneration through residents" participation. In other words, it is important to improve local capability by discovering local resources and values, and making the best use of them to give new values and grow them. In this sense, the core of Jeonju urban regeneration test-bed project lies in the strengthening of the local capability for sustainable urban regeneration, and the emphasis is placed on residents" participation, activation of the community and establishment of local governance. However, since Korea has no experience of promoting urban regeneration projects in this way, an intermediate support organization is regarded as a prerequisite. The analysis results and political implications of this study are as follows. First, the effect of social capital on local governance was found to be higher in a commercial district than in a residential district. Second, according to the results of the analysis performed through the medium of intermediate support organization, the indirect effect of 39% was presented for the commercial district. Third, systematization and effectiveness needs to be ensured in the establishment and operation of intermediate support organizations.

An empirical study for verifying the correlation of the sales between the large-scale discount stores and the traditional markets depending on the change of the commercial supremacy of the traditional markets has not been carried out yet. The main purpose of this study is to get the relative importance of business factors of the traditional market affecting a sales change of the big box retailer through the status of sales of each shop of the big box retailer. The results of an empirical analysis shows some certain pattern. First, the more adjacent traditional market are near Large-scale Discount store, the less Large-scale Discount store makes a profit. Second, the closer the distance between them is, the less Large-scale Discount store makes a profit. Third, the smaller the traditional market is, the more Large-scale Discount store makes a profit. Plus, the more Large-scale Discount store is away from Seoul, the more it makes a profit. We surmised that variable distribution contents help sales growth of Large-scale Discount store. We also introduced the grounds to analysis the relationship between the business factors of the traditional market and sales changes of Large-scale Discount store through this study.

A test-bed for a shopping district has been developed urban regeneration project with empowering business people as the central figure rejecting quantitative development established by government lead and activating a distressed neighborhood through its own efforts. Additionally, the main purpose of this project is to activate commercial supremacy by making the business people voluntary participation in the project and to strengthen of ability of them. This study analyzed impact of education program for business people on empowering of business people in the case of autonomous urban regeneration project. The result of the analysis showed that the program composition did not have impact on personal/internal change, interpersonal change and socioeconomic change. However, program operation showed to have impact on personal/internal change, interpersonal change and socioeconomic change. It is expected that the findings from the study can contribute to overcome the limitations of the previous programs on empowering business people and promote participation rate of business people by empirically analyzing the impact relation of the program and opportunities to plan the program with a new objective.

편의점은 기존의 낙후된 소매시설인 골목가게를 대체하는 현대화된 소매점으로 소비자의 편의성과 영세소매업자의 새로운 생계수단으로서의 위치를 점하고 있다. 그러나 최근 편의점의 출점 점포수의 증가에 따른 자사 가맹점과 타사 경쟁점의 출현으로 인한 상권축소로 편의점간의 상권경쟁이 더욱 심해지면서 국내 유통 자영업시장의 침체가 가속화 되고 있다. 이러한 문제인식을 바탕으로, 본 연구는 A사 위탁가맹 편의점 매출액 자료를 활용하여 영업환경변수가 매출액에 어떤 영향을 주는지를 파악하여 편의점 출점 및 기타 소매점포 창업 시 보다 효율적인 입지선정 및 운영의 시사점을 제시하고자 하였다. 분석결과 독립변수들 중 월세, 공시지가, 접면수, 영업면적 그리고 경쟁편의점의 유무가 편의점의 단위면적당 매출액에 영향을 미치는 유의한 변수들로 나타났다. 또한, 매출액에 영향을 주는 변수의 순서는 월세, 영업면적, 공시지가, 접면수, 경쟁편의점의 유무 순으로 나타났다. 따라서 본 연구결과를 종합해보면, 편의점의 최적입지는 상권이 활성화되어 있어 월세와 공시지가가 높은 지역이면서 경쟁편의점이 많지 않으며, 유동인구가 많은 도로의 접면지역이라고 할 수 있다. 한편 매장면적의 경우 부의 값을 나타내고 있어 상권의 활성화 정도에 따라 적정한 규모로 편의점 면적을 설정하는 것이 중요하다는 것을 알 수 있다. 본 연구결과는 지하철역 등 선행연구 등에서 제시된 영향요인 중 일부가 유의하지 않게 나타나 추후 보다 넓은 지역과 사례의 분석을 통한 연구가 필요하다고 할 수 있다.

The decline of traditional markets has led to sluggish local economy, which in turn has had an adverse effect on the national competitiveness. In response to issue, the government enacted a special law for the activation of traditional markets and has provided active support, while switching legal hierarchy from the law in time limits to the law in ordinary times. This study was intended to analyze the degree of activation of traditional market support projects promoted by the government for more than a decade based on the form of the merchant organization. To this end, a research was performed using common elements, activation factors and five forms of the merchant organization classified and examined by store management status survey of the Small and Medium Business Administration as data. According to the analysis results, the shopping district association showed the highest average score in market size as a common element, and private organization not controlled nor protected by law as for the size of commercial supremacy. In the case of the location, registered merchant association is situated in large city, and the registered merchant association showed the highest average score in the land area and floor space, and cooperative business association in the total floor area. In this regard, this study suggests an implication that a more formalized and structured form of the merchant organization which manages and operates traditional markets will contribute to a sustainable market activation.
