This study aims to develop the combined septic tank for middle-small scale sewage treatment. The developed process were circular and separate type. The circular combined septic tank was controlled sludge discharge and could be modified the advanced treatment system. The separate combined septic tank was could be applicated wastewater that discharge flow was varied, and was could be maintained F/M ratio constantly. The optimum hydraulic retention time was about 16 hours.

The study area investigated in this research is Hwaseong city, Gyeonggi-Do where small scale development is currently in progress. For the last three years, we carried out the environmental and ecological assessment by using data from The Ministry of Environment and Han River Basin Environmental Office. Most of development works in Hwaseong city, Gyeonggi-Do are small scale developments which are related with factory and distribution complex based on individual laws and regulations. However, environmental and ecological assessment is not being sufficiently reflected beforehand. Especially, because the development takes place mainly in the outskirts of the city, the fine forest is continuously being damaged. We analyzed changes in green zone area caused by the developments. As a result, the percentage of original green zone was decreasing while the percentage of artificial green zone was increasing. We should maintain the percentage of the original green zone in order to conserve natural environment. In the past three years, the damage of the DGN (Degree of Green Naturality) 7 area that has high conservative value was little, but, there was serious damage in the area of DGN 6. In order to conserve natural environment, political and institutional investigation should be seriously carried out for mitigation of environmental and ecological damages.

The aim of the research study is to carve sustainable business strategies for the fashion communities in Ethiopia and Ukraine which are suffering today due to ever-increasing share of fast fashion consumerism. Fashion houses and international brands propagandize sustainability and consumption for better consumer base, where as originally sustainable local-based craftsmen still stay in the shade. Four communities/local designers are selected from the countries through the method of purposive sampling. Qualitative analysis is the basis of the research as we performed personal interviews and in-depth analysis of the communities to diagnose the problems and subsequently devise the solutions. In this research, we have studied and analyzed the problems faced by hereditary communities and ethnic designers in small and medium scale enterprise sector from two emerging economies. After the grounding the difficulties faced we advised strategies for sustainable future growth to the companies. The current academic literature on small and medium scale enterprises highlights the problems and solutions for general industry sectors. This paper brings attention to fashion communities and designers who promote national heritage and are struggling to survive in emerging economies due to industrialization and globalization. Moreover the comparison of the two geographies is unique in nature.

Due to the event of hazardous chemical injection into a water storage tank in Hongseong, Chungcheongnam-do in 2012, the Korean Ministry of Environment has revised the enforcement rules of the Water Supply and Waterworks Installation Act to install surveillance equipments such as closed-circuit television(CCTV). However, the enforcement rules still do not provide concrete provision for installation of physical security equipments. Thus we studied vulnerability of small-scale water supplies in Korea and developed guidelines for the physical security system of the facilities. The guidelines include selection and recommendation of the physical security approaches and measures to detect, delay and response to the presence of an intruder in small-scale water supplies. The security features include protection utilities(e.g., fencing and fence topping), exterior intrusion detectors and alarms, locks and padlocks, surveillance utilities(e.g., CCTV), and others.

Computer-based modeling and simulation (M&S) techniques have become an essential component in the development of new weapons systems. M&S techniques provide a means to simulate military training, strategies, military doctrines, and weapons acquisition processes. This paper proposes a small scale engagement scenario generation method. This work also includes a process for scenario generation and visualization. The proposed scenario generation methodology employs the Timed-FSA (finite state automata) and DFS (depth first search) algorithms. The proposed scenario generation method is verified using a one-on-one combat engagement scenario between two submarines. In addition, we suggest a scenario generation process including whole scenario generation and scenario visualization.

소규모 전문도서관에서의 정보관리 활동을 고찰하기 위하여 동의대학교 도서관메일링리스트에 올려진 글을 분석하였다. 기업체 자료실을 비롯한 소규모 전문도서관에서의 활동은 도서관계에 거의 알려지고 있지 않다. 도서관메일링리스트에는 그들이 업무수행 중에 겪고 있는 어려움들이 질의 형식으로 제시되고 있다. 도서관리프로그램, 도서관 운영, 분류, 장서개발, 규정, 지식경영, 건의 사항 등 그들의 질의가 많이 나타난 주제를 중심으로 논의하였다.

The objectives of this study are to develope the automatic design programs to offer the data when constructing a small scale vinyl-house by region. This program consists of four subroutines. The first is an automatic greenhouse modeling program, the second is a calculating design load program by region, the third is a structural analysis program and the last is a optimum shape design program. The structural analysis can be conducted by simple date input and considering the design load of the install regions into account. The shape of input data is very simple, and the program reflects the design load by region. The output data can be obtained from the automatical calculation processing after structural analysis. The program was verified by compared with outputs of a common use structural analysis program and the results are the same. It was concluded that the developed program could be used efficiently in optimum design of small scale vinyl house.

A large scale seeding system was stable in terms of techniques but a convenient seeding system of small size was unsettled. This study was performed to develop a semi-automatic seeder for small and medium sized scale farm. To investigate optimum needle diameter and vacuum pressure was used vacuum suction needle seeder. Although the needle diameter according to the kinds of seed was different, the needle diameter for salvia and lettuce seed was suitable for 0.34 mm needle nozzle and 0.4 mm taper nozzle. The prototype consisted a seeding frame attached with needle nozzle, seed hopper, vibrating device, seeding part, vacuum ejector, seed tube etc.. As the result with the experiments, the seeding rate of the seeder was 92% and more at 0.34 mm diameter needle nozzle and 0.4 mm taper nozzle. Eccentric weight for seed hopper vibration was suitable that weight is 11 g and eccentric distance is 0.5 mm. Vibration acceleration of upward direction was 0.363 m/$s^2$. Working capacity of the seeder was possible 160 trays per hour. It was possible for sowing small seeds but it was required to make compact and simple model.

The objectives of the study are to improve techniques for social impact assessment and to suggest their measuring methods to apply in small scale rural development projects. Population, residence, industries, and traffic volumes were selected to measure the social and economic impact assessment of Seongeup agricultural water development project in Jeju Province. Existing data gathering methods were used to estimate the changes of population and traffic volumes. Interview schedule for villagers was applied to estimate the residents' satisfaction to living environments. Interview schedule for experts was applied to estimate agricultural productivity and land price. The results of social and economic impact assessment show that there will be considerable changes in living environments, agricultural productivity, and land price. On the contrary, the project will make little impacts on the changes of population, em-ployment, and traffic volumes.
