Isozyme PAGE에 의한 isozyme polymorphism 및 random amplified polymorphic DNA(RAPD) pattern의 비교를 통하여 한국에서 수집된 63개의 표고 버섯(Lentinus edodes)품종의 유연관계를 조사하여 보았다. NTSYS PC program을 통하여 비교에 사용되어진 3가지 isozyme 즉 esterase, peroxidase, acid phophatase 등은 각각 10, 7, 3개의 isozyme polymorphism type으로 나뉘어질 수 있었고, 이러한 3개의 isozyme type들은 group-average method를 이용하여 최종적으로 6개의 집단으로 구분되어질 수 있었다. 또한 RAPD를 통한 표고 품종간 유연관계 비교는 사용되어진 총 20개의 random primer 들중 3개의 primer(OPA 03, OPA 18, OPA 19)가 품종간 polymorphism을 보였고 사용되어진 전체 random primer의 PCR product들의 집단 분석을 통해 최종적으로 5개의 집단으로 구분할 수 있었다. 사용되어진 두 가지 방법 즉, isozyme polymorphism및 RAPD pattern에 의해 구분되어진 63개 표고 버섯 품종의 subgroup level에서의 절대적인 유사성은 관찰할 수 없었다. Yii-Mattila(1996) 등에 의하면 품종간 비교시 isozyme analyses에서와는 달리 RAPD analyses에서는 많은 수의 strain-specific band들이 얻어질 수 있고 이것이 두 방법간의 유사성을 관찰하지 못하게 하는 원인이라고 보고하였다.

Thailand is a country of native beef cattle resource farming. It has undergone rapid social and economic change in the past decade. Agricultural growth has been maintained by increasing the production of rice and cassava. Changing economic status also provides opportunities for beef cattle producers to meet increasing consumer demand for beef. Finishing beef cattle numbers in Thailand were about 1.0 M head in 2015. Beef produced in Thailand has exclusively been for domestic consumption. Only 1% of Thailand's beef cattle are for the premium market which is based on marbling score, 40% are sold into modern markets that consider muscling of cattle, and the remainder enter traditional markets. Cross-bred cattle for the premium market are raised within intensive systems. Most producers of premium beef are members of beef cooperatives, or have invested in their enterprises at high levels. Culled cow (native or cross-bred cattle) are mainly for small holder farm production. Malaysia, Indonesia, and other members of the Asian Economic Community (AEC) are set to become the largest beef market, which has been confirmed by 2015 through 2020 forecasts for consumption of beef that must increasingly be halal. These circumstances are likely to be challenging for beef producers in Thailand to gain a share of this market. Integration across all sectors involved in beef production in Thailand will be required.

The medical insurance system has been adopted in 1989. Since then, the utilization of medical care services has increased rapidly. It appears that the medical institution needs more nursing manpower such as nurses and nurse aides to meet an increased demand for medical care for the residents. However, the medical care clinics run by a medical practitioners has a more shortage of nursing manpower than hospitals. The purpose of this survey was to analyze the current employment status and to obtain an opinion on the improvement of utilization such as recruitment and retention of nursing manpower. The questionnaire sent to the private physician and the response rate was 28.7% ; 87 out of 300 physicians. 82.6% of the respondents employed nurses aides rather than nurses and an average number of employees per clinic was 2.5 persons. Most physicians had difficulties in recruiting nursing manpower. It took more than one month for replacement on average, therefore, they were suffering from giving good continual care for the patient and also high resignation of nursing personnel. The low wage, long working hours, hard work and lack of incentives are the biggest reasons for the difficulty in recruiting and retaining of the nursing personnel obtained for the clinics survey. The above mentioned problems would be solved in the near future by changing those difficulties. In the meantime, the private physicians are marking an effort to retain the nursing personnel by keeping a relationship of the private physician's cooperatives.

As an important factor of capitalism economics, price of commodities represents a certain country's economic index. For having correct price policy, there should be an appropriate mechanism to make and use systematic statistical data on price. Price statistics are made by indexes and price indexes are categorized into producer price index(PPI) and consumer price index(CPI). The Bank of Korea is publishing producer price index every year, but the producer price index contains some problems. These include as follows : (a) the impractical selection of fisheries products sample (b) uncorrect measure of aquatic products weights (c) investigating sample places. This study try to substitute producer price index of aquatic products and change construction of fisheries producer price index with experimental research on representative fisheries, weight of each fisheries, and suitability of investigating sample places. It is possible to improve practical fisheries producer price index with the results of this research. The findings are as follow. (a) It will be helpful for the government to make the fisheries price policy. (b) It can be used to understand trends of accurate price and price increase of aquatic products, and it's possible to compare with it other industrial indexes including the mining, agricultural, and manufacturing industry and understand relative price movement. (c) When free sales systems of fisheries products as expected, it will be helpful to analyze price movement of producing fisheries cooperatives, producing fisheries market and consuming fisheries market, analysis of market, and formation and consideration of budget. (d) It can be an important index to determine labor wage.

Since the human civilization, people's livelihood is dependent on natural resources primarily on forest. Human dimensions such as population, poverty, agricultural expansion and infrastructure development are some of the underlying factors and their interrelated associations which could play a vital role in deforestation and forest degradation. This process is not only related to the human population but also connected to the various socioeconomic factors. This paper focuses to link the spatio-temporal extent of population, poverty incidence and forest dependency and their severity on Terai forest of Nepal. Secondary data on censuses were used. ArcGIS and descriptive statistics were also used for data analysis. Based on analysis & literature review we concluded that population, poverty and forest dependency have largely expanded over time in Terai and their interrelated associations substantively influence on deforestation. However, the direct relationship of such factors with deforestation and forest degradation found to be incompatible, complex and hard to perceive with fragmented and inconsistency censuses data. So, deforestation and forest degradation issues intertwined with socioeconomic factors need detailed analysis to comprehend where these linkages are still unravel.

This study aims to examine the determinants affecting rural women's participation in community organizations in rural Korea. The data was collected through interviews with 958 rural women among 1,870 respondents who have lived in Up and Myen as an administrative unit of a rural community, and analyzed by the SPSS/PC Win V.10 program. The statistical method utilized for this study was the hierarchy multiple regression model. The major findings of this study were as follows. First, rural women with a high income, a larger farm, or a fruit farm are more likely to participate in agricultural cooperatives. Second, rural women with a high income, a larger farm, who are engaged in full time forming, and grow fruit and special crops, are more likely to participate in cooperative firms. Third, rural women who are educated and have a larger farm, a fruit farm, and high community attachment are more likely to participate in learning organizations. Fourth, rural women who were educated and have small households are more likely to participate in religious groups. Fifth, rural women with a small farm are more likely to participate in civic organizations. Sixth, there was no significance between all of these variables and participation in political parties.

Shiitake (Lentinula edodes) is the most economically important cultivated mushroom, but yields are impacted by its competitor, Trichoderma spp. We previously found two unidentified Trichoderma species growing in bedlogs and sawdust shiitake media in Korea. Here, we identify and re-describe those two species based on molecular sequence data, morphology, and culture characteristics. Well-supported clades based on phylogenetic analyses of internal transcribed spacer, translation elongation factor 1-${\alpha}$, and RNA polymerase subunit II sequences grouped one of the unidentified Trichoderma spp. with Hypocrea pseudogelatinosa and the other with Hypocrea pseudostraminea, and their morphologies matched well with the original descriptions of the two Hypocrea species. This study reports the first phylogenetic analyses of H. pseudogelatinosa and Japanese strains of H. pseudostraminea. Based on the phylogenetic results, we redescribed these two species using modern taxonomic concepts in Hypocrea/Trichoderma.

Since 1970, China has become the biggest cocoon producer in the world, and made the highest historical record of cocoon output for 759,800 tons in 1995. However, in 1996 cocoon production reduced sharply to 470,900 tons. After a ten-year adjustment and reform, sericultural areas have shifted from developed regions to developing regions and from the east to the west. From 2000, the cocoon output has started to increase restoringly. By 2004 it recovered to 547,091 tons. With the development of market economy, sericulture management has been changed, including mulberry fields concentrated to the specializated households and cooperatives, cocoons produced in larger scale instead of individuals, Silkworm egg producing enterprises gradually changed into non-governmental joint-stock ones. The mechanism of market cocoon price has been gradually established. The management model of combination of trade, industry and agriculture is pushing and improving. It is the fruit of modern science and technology, especially sericultural basic research, that provides China's sericulture with the opportunity and vital force. China's sericulture, therefore, will continue to develop steadily in future.

This research examines the financial performance of Village and Urban Community Funds (VFs). The study also explores the beneficial effects of the biggest microfinance programs in the world in the lower and lowest income provinces; specifically, whether VFs change household economic status or not. The data is collected uniquely from the village funds in four provinces of each region in Thailand which considerably reflect the government achievement. Accordingly, several financial ratios have been applied to evaluate the financial efficiency of the village funds, and the ordered logit model has been used to estimate the impact on economic variables of the poor. The findings show that the village funds do not improve the savings, income, consumption, and asset of VFs' members, although such funds have a higher financial performance. Furthermore, the VFs are a good substitute compared to the Bank for Agriculture and Agricultural Cooperatives (BAAC) credit because the cross-price elasticity of quantity of demand for such loans is positive. In particular, the loans from village funds are insignificantly correlated with the debt, income, asset, and economic status of VF members. This implies that Thai Village Funds do not alleviate definitely the serious problem about the financial situation in rural provinces. Thus, this microfinance does not change the economic well-being of the poor.
