Recently agricultural situations are being placed in unfavourable socio-economic environment as followed by rapid decrease of rural population, poor labor quality and high wages of rural society due to high speedy industrialization of social structure in Korea. In addition to those circumstances, under the UR system to be expected in the early future, free trade of agricultural products will be faced inevitably in Korea. Practically prices of rice as a principle food in this country are expensive about three times compared to those of foreign rice markets, and so how to increase the international competitiveness and food supplies are important problems to be solved rapidly. Accordingly an urgent goal is reduction of agricultural production cost by the improvement of labour productivity as a labour saving and cost down cultivation methods as the direct seeding cultivation in rice. But there are many problems in the direct seeded rice cultivation. The important things to be improved in that cultivation are development of rice varieties with lodging tolerance, effective seedling stand, weed control, irrigation management and fertilizing and so on. Moreover agricultural basis as irrigation facilities, land consolidation and farm machineries must be improved for the stability of rice cultivation in the future.

Waste glass is a global solid waste with huge reserves. The discarded waste glass has caused a series of problems such as resource waste and environmental pollution, so it is urgent to recycle waste glass with high replacement level. Glass powder (GP), as a supplementary cementitious material (SCM), used in cement-based materials has already become one of the important ways to recycle waste glass mainly attributed to its pozzolanic reaction and filling effect, especially to the suppressed ASR expansion. This paper demonstrates an overview of the properties of GP and its effect on the fresh and mechanical properties of cement-based materials. The study found that the influence of GP on the performance of cement-based materials mainly depends on its content, particle size, color and type, curing conditions, and other SCMs. Finally, based on the problems involved in the investigation of concrete containing GP, some corresponding suggestions and efforts are given to further guide the utilization of GP in cement-based materials.

The agricultural development of Korea has occurred at the expense of natural resources and environmental quality, and, today, one of the most urgent problem in the practices of intensive livestock farming is disposing of the animal wastewater. As a result, soil and water degradation and other environmental deterioration become apparent and they cause long-term loss in agricultural production. This paper attempted to summarize the environmental problems associated with agricultural activities, and to get some implications to minimize agricultural environment problems. It is proposed that sustainable agricultural is one of desirable directions for future Korean agriculture. The goal of the sustainable agricultural effort is to utilize the potential environmental quality problem. Agricultural operations may be more dependent upon the production practices and waste management techniques utilized by farmers than the size of the operation, the number of animal fed, or amount of waste involved. Also low-input farming technology can be suggested one of them, and disposing system of agricultural residues and animal waste should be developed with intensive concerns and financial supports.

Purpose: The objectives of this study were to understand and compare perception and experience between clinical staffs(nurses and pharmacists) and Quality Improvement managers. Method: A qualitative study was conducted with 14 clinical staffs and QI managers who are working at tertiary hospitals in Korea. Interviews were recorded and transcribed for systematic analyses of qualitative data. Results: Most critically, while QI managers acknowledged that establishment of the patient safety culture and reduction of medical errors are urgent tasks for QI effort, clinical staffs don't seem to share such perceptions. All participants agree that staff shortage and no compliance to safety procedures were major reasons for medical error occurrences. Many suggested that an organizational culture where errors were perceived as a systematic problems rather than individual failures or carelessness should be formed to promote voluntary reporting of medical errors. Conclusion: A more systematic effort and attention at the hospital leadership and public policy level should be promoted to constitute societal consensus on the urgence of promoting patient safety culture and more specific approaches to tackle the patient safety problems.

Such effects would be paid off in the right way only when management of the firms perform marketing activities focusing on long term effectiveness, which would drive company profits up and keep them for long. Demands of customers are being changed and varied. In this result with the advantage of mass marketing and database marketing have been drawing attentions from company. To fulfill these demands of customer, they need a concept of eCRM(Web based Customer Relationship Management), and go from selling products and services, or gathering customer requests, up to the phase of solving customer's problem by real time or previous action. With the help of internet, the frequency and speed of the problem solving has improved greatly. For these purposes, we try to determine the most important and most urgent factors in eCRM: utilization by using SN Ratio Decision making, one of the Multi-criteria decision-making methods SN Ratio Decision making is widely used for determining relative magnitude per evaluation item, i. e. priority on problems and is expected to make more systematic and objective evaluations than conventional methods do. Even in the present situation where any general criterion on eCRM dose not exist, utilization of eCRM is expected to be actively continued, which will cause many problems. In this regard, evaluating eCRM counts.

China and Southeast Asia share intimate relationships based on close spatial, temporal and human conditions. Thus, Southeast Asian studies in China boast of a long lineage of 'traditional', 'embryonic', 'closed' and 'opened' Southeast Asian studies. In the modern period the 'embryonic Southeast Asian studies,' professing conservative nationalism based on traditional Sino-centric perspectives, accumulated elementary knowledges on the history of Sino-Southeast Asian relations and Chinese communities in Southeast Asia. On the other hand, 'closed Southeast Asian studies' standing for radical Communism suffered from chronic stagnation. After the Reform and Opening, 'opened Southeast Asian studies' recorded impressive progress in the restoration and development of Southeast Asian studies. Nevertheless, 'opened Southeast Asian studies' are faced with some serious problems such as biased perspectives, traditional methods, and national subjects. Most of all, it is urgent to overcome Sino-centric perspectives on Southeast Asia. Despite the opening of Southeast Asian studies to the diverse methods of modern social sciences, descriptive studies prevail over analytical ones. Regardless of the diversification of subjects, national questions such as the overseas Chinese and cross-border nationalities are prone to excessive nationalism.
