The purpose of this study was to develop a ridge regression (RR) model to estimate BOD and TP load using runoff weighted value. The concept of runoff weighted value, based on distributed curve-number (CN), was introduced to reflect the impact of land covers on runoff. The estimated runoff depths by distributed CN were closer to the observed values than those by area weighted mean CN. The RR is a technique used when the data suffers from multicollinearity. The RR model was developed for five flow duration intervals with the independent variables of daily runoff discharge of seven land covers and dependent variables of daily pollutant load. The RR model was applied to Heuk river watershed, a subwatershed of the Han river watershed. The variance inflation factors of the RR model decreased to the value less than 10. The RR model showed a good performance with Nash-Sutcliffe efficiency (NSE) of 0.73 and 0.87, and Pearson correlation coefficient of 0.88 and 0.93 for BOD and TP, respectively. The results suggest that the methods used in the study can be applied to estimate pollutant load of different land cover watersheds using limited data.

North-South Korea economic integration is progressing slowly given the sensitive responses to changes in internal and external conditions. Nevertheless, advanced discussions focusing on North-South Korean economic cooperation should continue. Given this background, various studies of the economic effects of economic integration between North and South Korea have been conducted, but research on agricultural issues has been limited. The purpose of this study is to analyze the impact of the economic integration of South and North Korea on the agricultural market. In this study, a simultaneous equation model was constructed using a growth model. Solow's growth accounting approach is used to construct a model for estimating the macroeconomic effect of North-South economic integration. Also, the construction of growth accounting formulas subdivided into South and North Korea as well as agriculture and non-agricultural fields during the construction of the growth model is a major research achievement and differentiates it from previous studies. It is expected that the results of this study will serve as basic information for preparing policy measures to promote integration. However, there are many limitations when estimating the economic effects of North-South agricultural integration and obtaining policy implications given the insufficient available statistical data on agriculture in North Korea and the lack of related studies in the agricultural field. Therefore, it should be noted that there is an inherent problem in that the analysis results vary greatly depending on the assumptions set, as there is inevitably no choice but to rely on many and strong assumptions.

The purpose of this study was to know the seed longevity of rice (Oryza sativa L.) germplasm for effective viability monitoring. The longevity was determined via germination tests of 3,066 accessions of rice germplasm from the National Agrobiodiversity Center, Rural Development Administration, Korea. The rice germplasm accessions have been conserved at a mid-term storage ($4^{\circ}C$, 30% RH) in plastic bottle containing dehydrated (blue) silica-gel and long-term storage ($-18^{\circ}C$, 35% RH) in hermetically sealed metal can on either sides for 25~26.5 years. The final germination percentages of 3,066 rice germplasm accessions of $6.5{\pm}1.0%$ seed moisture content with 94% initial germination stored at $4^{\circ}C$ for 26.5 years declined to 47% while at $-18^{\circ}C$ for 25 years maintained high germinability as 93%. Germination time courses, which represent the average performance of rice ecotypes stored at $4^{\circ}C$ and 30% RH, were fitted regression equation, to calculate the time at which germination characteristically declined to 50% ($P_{50}$). These $P_{50}$ values of Indica, Japonica, Javanica and Tongil type in rice were 39.9, 22.9, 25.4 and 31.8 years, respectively. The rice germplasm stored at $4^{\circ}C$ could be clustered in 4 groups using quartile of final germination after 26.5 years storage. The seed longevity ($P_{50}$) of each group was estimated by regression equation of changed germination percentages according to storage periods. The $P_{50}$ values of group I, group II, group III and group IV were 21.1, 23.6, 30.0 and 75.7 years.

Malawi's agricultural extension system has been subjected to a number of criticisms in recent times for failing to contribute significantly to agricultural development and for not responding to the needs of the smallholder farmers. Despite this, extension is still seen as key to improving poverty and rural livelihoods.There is a number of challenges facing extension that require a response from the public sector and other stakeholders. A clear and positive response to these challenges will help shape the future of agricultural extension in Malawi for the benefit of all farmers and the attainment of the broad policy objectives of government: democratization, market liberalization, decentralization, HIV/AIDS crisis, shrinking public sector resources, public sector reform, and co-ordination, etc. The mission is to provide pluralistic demand driven extensions services and promote equalisation and co-ordination in service provision in order to achieve food security at household level, there-by reducing poverty. On the other hand the vision is that 'All farmers' demand and access high quality extension services from those best able to provide them'. DAES implements its extension policy through the District Agricultural Extension Services System (DAESS), based on Model Village Approach.

Department of Health Services, under the Ministry of Health, Nepal has adopted the five year plan and Primary Health Care service as the main strategy to provide basic health service at the rural areas. However, development of the Specialized Services in the Urban areas, Human Resource Development, Management Strengthening and Investment of Private and External Sector are also highly entertained through its Liberalization Policy. But due to, Early Marriage, Superstitious Traditional Beliefs ＆ behavior, Poor Sanitation of living, Poverty, Illiteracy, Lack of Supervision and Monitoring, High Density population in relation to arable land and Lack of Private and External Sector Investment, the Country is still suffering from high Fertility, Malnutrition, Infectious diseases and so high Death Rates. So Primary Health Care Services should be more emphasized than before; Community Financing, Private and External Sector should be highly involved; Manpower Development and Specialized Services should be most taken care; Management Skills be more strengthened and Evaluating the previous work and avoiding the mistake for the future program implementation should be well done. If these are improved, then the health will be definitely promoted to meet the Health Target of Nepal.

Due to the increasing needs of land supply, green space has been continuously encroached and resulted considerable naturality deterioration in Korea. In order to overcome the problem, it is necessary to introduce a integrated system for managing the quantitative and qualitative aspects of green space. With this regard, this study is to derive the feasibility for the adoption of the 'no net loss of green' policy to Korea from German and Japanese experiences. In Germany, natural resources are protected and inevitable damages were compensated through the adoption of 'interference regulation'. In Japanese case, future green space and artificial green foundation should be specified on the green basic plan which pursuit the improvement of naturality. In order to introduce the 'no net loss of green' policy to Korea, not only awareness raising on integrated green management system but also amendment of related regulations are needed. In detail, restoration and recovery on the damaged nature should be clearly elucidated and indicators to evaluate the current naturality and calculation methods for the restoration should be developed. Should this integrated green management system introduced, deterioration of naturality by development activities could be minimized thorough the adoption of land development permission criteria and green space management methodologies.

In this era of information and communication technology (ICT), efficient and cost effective public services delivery had become highly expected by the citizen in every country. In developed countries, digitally enabled public services were established in recent years while the developing countries like Bangladesh were trying to establish this advancement. The UNDP, USAID and the Government of Bangladesh launched the Access to Information (A2I) programme to improve the services delivery to reach at the doorsteps of citizen. Under this umbrella, Union Digital Centers (UDCs) were launched in 2009 at every Union of Bangladesh to reduce the "Digital Divide" in public service delivery. Thus, it had become the concern nowadays to make this initiative sustainable for a long run, this study focused to find out some key factor to be considered for making them sustainable in Bangladesh. It explored the previous researches related to these centers and same categories of institutions in other countries where the researchers argued about some issues in different aspects. Based on their findings and discussions, this study tried to analyze the key issues influencing the sustainability factors. To analyze the factors for sustainability, it addressed the financial, investment, business development and publicity, competencies of entrepreneurs, community acceptance and gender issues, institutionalization and physical infrastructure concerned with UDCs. The Government agencies, policy makers, researchers could be consider those recommendations for developing the strategies for sustaining the operations of UDCs in Bangladesh.

Traditionally, students from the Southern world tend to cross their national borders to study abroad. However, in recent times, we have observed a trend in which more and more students, both full-time and short-term, select Southern countries as destinations for overseas education. This paper contributes to the sparse literature on the above phenomenon, examining the case of Vietnam. We surveyed 50 universities and colleges about their international student profiles (including statistics and nationalities) and their strategies for attracting international students. The findings of this study provide implications for Vietnam's policymakers and university/college leaders and other Southern countries when implementing the internationalization of tertiary education.

Injury in agriculture is a serious public health issue with a major impact on the lives of Korean farmers. It is one of the leading causes of death and is also a major cause of longand short-term disability. In 2001, the social cost of one accident in agricultural machinery was estimated as 97.7-97.8 million won that is 4 fold of farm household income in Korea. Effective prevention and control of injuries requires a system of surveillance that monitors the incidence of injuries, their causes, treatment and outcomes. This requires an integrated system of data collection, analysis and interpretation and communication. Creating effective injury surveillance system in Korea requires to establish a framework for a national agenda. Discussions regarding the development of the framework should address, but not be limited to issues related to Data Holdings and Linkages; Capacity and Skills; Communication; Interconnection; and Surveillance Products. Ideally, an injury surveillance system would meet the information requirements across all sectors, while allowing each to have the ongoing information it needs for its policy and programming needs. This study was carried out to develop a surveillance system of agricultural injuries in Korea. Study subjects were residents who lived in a typical agricultural area (Yangpyung area in Kyung-gi province). The main data sources were reports of village headmen, compared with data of 'National Emergency Management Agency', 'National Health Insurance Corporation', 'Insurance of National Agricultural Cooperative', and 'Emergency Medical Centers'. Each data were reviewed to validate the strengths and weaknesses.
