After the rapidly changing business management environment and financial crisis, high prices and domestic recession in Korea posed threats to the business survival of small and medium enterprises (SMEs). This paper looks at the potential of micro business owners for sustainable development: those who have a spirit of entrepreneurship and the potential to be a hidden champion. Our study of micro business values uses structure equation modeling by LISREL. We have done so in order to understand the foundation of management innovation and success model of micro enterprise by increasing the entrepreneurship and management performance relationship analysis. A micro-enterprise is a type of small business, found only in Korea, often registered as having ten or fewer employees. We examine the successful type of hidden champions and the influence of entrepreneurship on start-ups in business. As compared to past research on the SME entrepreneurship, this study segments small businesses even further. Small business entrepreneurship was classified into three forms that are most appropriate for the Korean situation today: innovation, risk-taking, and pro-activeness. This research is meaningful as it is Korea's first empirical analysis on four business types: wholesale and retail sales, food and lodging business, service business, and manufacturing business. Thus far, research on small business entrepreneurship was carried out using small-scale investigative analysis. However, this research attempted to develop a model that can explain a cause-effect relation of the motivational level when it comes to the difference of entrepreneurship by each business type and small business start-up success factors. Various conceptual and operational definitions could be developed in a diverse and precise manner. Independent variables that are related to the success of small businesses can be developed additionally to examine the success factors related to the systematization in detailed manner. The research showed that the innovation, risk-taking and pro-activeness of the manifested difference in the degree of perception depending on the type of small businesses. Among the four business types, the ones that manifested the highest successful start-up rates were food, service, wholesale and retail sales and manufacturing. Results after conducting the regression analysis are shown on, which proves that the small business entrepreneurship exerts direct effect on the financial management performance of small businesses. In other words, small business entrepreneurship exerts a positive effect on the small business financial success and management performance. The R² value is 0.61. It is possible to know that the perception of systematization and variables on attitude explains the 61% of the success for small self-employed businesses management performance. We define start-up key factors that are helpful to achieve internal growth of firms by finding business survival strategies. The results also focus on Korean government policy for micro enterprise and small business support.

Composting is an ecologically sound method of recycling organic waste. Its advantages include the maintenance of soil fertility and improvement of soil physicochemical property. It is an essential part of the waste minimization. That is, composting should be included to increase the recycling rate up to more than 20%. To encourage composting of waste, it is necessary to develop some effective composters of small scale facilities and densely populated areas. For medium and large-size facilities, the optimum process should be selected. Technical counselling and support is desirable for small scale composters for urban residential and rural area. On the other hand, adequate amendment of relevant legislation should be followed to encourage composting. An example of unreasonable legislation is the current fertilizer management act. According to the regulation, the maximum allowable limit of lead in the compost is less than 150ppm, which is too strict. This limit should be increased to at least 300ppm, which is the observed level in most states in USA. At the same time, sound infrastructure should be established and decent publicity work should be achieved to accelerate composting activity. In this paper the desirable standard for some heavy metal concentration in the compost were suggested.

A new wave-absorbing system, called the liquefied sandbed wave barrier (LSWB) system, is currently under development at the Port and Airport Research Institute (PARI) of Japan. The wave damping effect by the LSWB system is substantial, as confirmed by small-scale experiments and FEM numerical calculations, i.e., the wave transmission coefficient of the system is less than 0.2. Here, the results of large-scale experiments arediscussed in view of practical application. Although the LSWB system provides high wave damping, nearly equal to theoretical values, difficulty exists in obtaining a homogeneously liquefied sandbed, due to the occurrence of liquefied sandbed compaction by cyclic wave loading, which in turn, reduces excess pare pressure and the wave damping effect. These two phenomena primarily occur when the sandbed is composed of fine sand with small permeability. Based on experimental results, we propose a design method that includes countermeasures against such problems, and a prototype LSWB system is constructed in a very large wave flume at PARI. Wave damping by the prototype LSWB system is confirmed to be quite stable and high, as predicted by theoretical calculations.

세계적으로 물의 부족, 온실가스 배출증가, 에너지 소비 증가 등으로 인하여 지구가 위협받고 있다. 기존의 도시 계획 및 개발 과정에서 산림, 하천 등 자연 생태계가 파괴되어 왔으며 이는 불투수면의 증가를 초래하였다. 불투수면의 증가로 인하여 자연적인 물순환 체계가 파괴됨에 따라 도시내 물의 저류, 침투, 증발 등이 감소되고 있으며, 강우시 불투수면에서 발생하는 비점오염원이 하천 및 호소로 직접 유입되어 수계에 악영향을 끼치고 있는 실정이다. 본 연구에서는 강우시 불투수면에서 발생하는 비점오염물질을 저감하고 불투수면의 증가로 인한 도시지역의 온도증가, 열섬현상 등을 해결하는 소규모 HSSF 인공습지 기술을 개발하고자 한다. HSSF 인공습지는 표면에 물이 존재하지 않고 유체의 흐름이 표면 아래 수평으로 흐르는 습지이며 침전, 여과, 흡착, 식생에 의한 흡수 등의 기작을 포함한다. 이러한 HSSF 인공습지를 도시지역의 협소한 공간에도 적용이 가능한 소규모 형태로 개발하고자 pilot-scale test를 실시하였으며, 이러한 연구결과는 향후 국내 도시 열섬현상 저감 및 자연적 물순환 복원을 위한 시설 개발에 기초자료로 활용 될 것이다.

자연정화공법에 의한 농촌 전원 독립가구 하수처리공법 개발을 위하여 호기성조와 혐기성조가 분리된 소형 하수처리 장치에서 혐기성조 위에 호기성조를 포갠 일체형으로 공법을 개선한 소형 하수처리장치를 설계 및 시공하여 하수처리공법별, 하수 부하량 및 하수 주입방법에 따른 수처리 효율을 조사하였다. 소형 하수처리장치의 최적공법은 호기-무산소-혐기조건이었으며, 최적여재는 쇄석이었고, 최적 하수 부하량은 $1,200L/m^3{\cdot}day$이었다. 이러한 조건에서 농촌 전윈 독립가구에서 간헐적으로 배출되는 하수에 대한 대응성을 조사하기 위해 하수 주입방법에 따른 하수처리효율을 조사한 결과 농촌 전원 독립가구 하수처리공법으로 개발된 호기-무산소-혐기조건인 소형 하수처리장치는 실제 농촌 전원독립가구에서 간헐적으로 발생되는 하수에 그대로 적용하더라도 현행 방류수 수질기준인 BOD 20 mg/L, COD 40 mg/L, SS 20 mg/L, T-N 60 mg/L 및 T-P 8 mg/L을 만족할 뿐만 아니라, 방류수 수질기준이 앞으로 BOD 10 mg/L, T-N 20 mg/L 및 T-P 2 mg/L로 강화되더라도 안정적으로 처리될 수 있을 것으로 판단된다. 이상의 결과에서 농촌 전원 독립가구 하수처리공법으로 개발한 호기-무산소-혐기조건인 소형 하수처리장치는 BOD 99%, COD 95%, SS 99%, T-N 83% 및 T-P 96%초 질소 처리효율을 호기성조와 혐기성조가 분리된 소형 하수처리장치에 비해 17%정도 향상시켰으며, 모든 조가 일체형이므로 부지면적을 최소화할 수 있다. 따라서 본 공법은 자연정화공법의 단점을 보완할 수 있으므로 농촌 전원 독립가구에 적합할 것으로 사료된다.

This paper describes the development of a scale for measuring top management commitment towards continual quality performance improvement in small and medium-sized enterprises (SMEs). A set of self-assessment questions of the ISO 9004: 2000 Standard was used to assess the adoption status of quality management practices. This paper investigates the inter-item reliability and the content validity of the Quality Management Principles Scale (QMPS) in an integrated improvement process in SMEs. An empirical study was conducted to acquire senior management views on the use of the QMPS in manufacturing sectors in Trinidad and Tobago. Based on 328 responses from 110 SMEs, statistical software packages were used to analyse the empirical data and determine the reliability and validity of the QMPS. The paper contributes to develop a self-assessment scale that can be used to measure top management commitment. It is anticipated that the findings would provide practical insights for evaluating the levels of maturity on performance improvement in SMEs.

A parallel condensation algorithm for efficient dynamic analysis of three-dimensional large-scale structures is presented. The algorithm is developed for a user-friendly and cost effective high-performance computing system on a collection of Pentium processors connected via a 100 Mb/s Ethernet LAN. To harness the parallelism in the computing system effectively, a large-scale structure is partitioned into a number of substructures equal to the number of computers in the computing system Then, for reduction in the size of an eigenvalue problem the computations required for static condensation of each substructure is processed concurrently on each slave computer. The performance of th proposed parallel algorithm is demonstrated by applying to dynamic analysis of a three dimensional structure. The results show that how the parallel algorithm facilitates the efficient use of a small number of low-cost personal computers for dynamic analysis of large-scale structures.

This study is aimed to establish the development plannings for the sustainable tourism of Yongyoo Island and Mooeui Island, neighboring areas of Youngjong Island, for the conservation and environmentally friendly use of Korean coastal wetlands. The concepts of sustainable tourism is described. The current development status and its problems of Youngjong Island and its neighboring areas are analysed. The development plannings for sustainable tourism of Yongyoo Island and Mooeui Island are suggested as follows : (1) The small scale tourism development projects, which are able to represent region's own characteristics, instead of large scale ones, should be performed. (2) The participation of community people should be guaranteed at the beginning stage of the decision making processes for tourism development projects. Additionally, the profits of the development should be fairly distributed among community people. (3) The coastal wetlands should be conserved and their sewage disposal capacity should be protected by way of the minimization of reclamation. (4) The coastal wetlands should be developed into the tourist resorts utilizing migratory birds as tourism resources. In addition, the carrying capacity of the coastal wetlands, which is based on the current status of ecosystems and the Environmental Impact Assessment(EIA), should be calculated.
