Rice farming is not only the most important income resources of Korean farmers but also the roots of Korean traditional culture. Paddy fields have acted as an food supply base but also have contributed to the public multi-functions such as flood control, water conservation, controlling soil erosion, providing recreational and resting spaces, water purification, air cleaning, oxygen supply and air cooling and so on. The public multi-functions of paddy except rice production have not been evaluated before UR negotiation and starting WTO system. Under the drastic changes of rice economic settings as price decrease of rice and downward decrease of farm income, Korean and Japanese farmers might have lost their intention to grow rice in paddy fields without the direct payment system to compensate rice income decrease. To adapt the direct payment system, the total public value of multi-function of paddy should be identified in terms of money. According to the research results, the total value of multi-functional value of paddy in Korea were estimated 21,596thousand won which is higher than rice production value by 2.1 times. On the other hand the total value of Japanese paddy were amounted to 21,390 Yen which is more than that of Korea by 10times outstandingly. Likewise Japanese have evaluated the paddy field very important enterprise from the view point of food security and multi -functions of paddy to their socio-economic life and environmental sustainability in Japan.

This paper deals with the economic value analysis of meteorological forecasts for a hypothetical inventory decision-making situation in the pharmaceutical industry. The value of Asian dust (AD) forecasts is assessed in terms of the expected value of profits by using a decision tree, which is transformed from the specific payoff structure. The forecast user is assumed to determine the inventory level by considering base profit, inventory cost, and lost sales cost. We estimate the information value of AD forecasts by comparing the two cases of decision-making with or without the AD forecast. The proposed method is verified for the real data of AD forecasts and events in Seoul during the period 2004~2008. The results indicate that AD forecasts can provide the forecast users with benefits, which have various ranges of values according to the relative rate of inventory and lost sales cost.

The reformed family law was enforced from Jan.1,1991 and the claim to division of matrimonial property in case of divorce, a newly enacted right in the law, is expected to increase the economic position of married women. By this system, married woman can claim her share in the matrimonial property in case of divorce if she verifies her contribution to it. But actually, household work of housewives has not been evaluated properly as compared with their husbands' work in deciding of property division rate, because there is no economic base about the value of household work. So, this study verified wives' role of contribution to matrimonial property and compared their work hours with their husbands. As the result, following suggestions can be presented. 1. The contribution rates of husband and wife to the matrimonial property have to be acknowledged equally and, in case of employed wife, her rate has to be evaluated higher than her husband. 2. Because the property division is not a solatium but a transfer of wife's share, responsibility which marriage has dissolved should not be taken more to women than men. 3. Decision of division rate has to be made regardless the amount fo property unless there are special reasons. 4. The donation tax and inheritance tax should not be imposed on matrimonoal property which was returned to wife from her husband.

A case study is presented where a fluvial system is modeled in three dimensions and compared to data gathered from a study of the Arkansas River. The data is unique in that it documents changes that affected a straight channel that was excavated within the river by the U.S. Army Corps of Engineers. Excavation plan maps and sequential aerial photographs show that the channel underwent massive deposition and channel migration as it returned to a more natural, meandering path. These records illustrate that stability of fluvial system can be disrupted either by catastrophic events such as floods or by subtle events such as the altering of a stream's equilibrium base level or sediment load. SEDSIM, Stanford's Sedimentary Basin Simulation Model, is modified and used to model the Arkansas River and the geologic processes that changed in response to changing hydraulic and geologic parameters resulting from the excavation of the channel. Geologic parameters such as fluid and sediment discharge, velocity, transport capacity, and sediment load are input into the model. These parameters regulate the frequency distribution and sizes of sediment grains that are eroded, transported and deposited. The experiments compare favorably with field data, recreating similar patterns of fluid flow and sedimentation. Therefore, simulations provide insight for understanding and spatial distribution of sediment bodies in fluvial deposits and the internal sedimentary structure of fluvial reservoirs. These techniques of graphic simulation can be contributed to support the development of the new design criteria compatible with natural stream processes, espacially drainage problem to minimize environmental disruption.

Many researches of aqua exercise, one of effective management for arthritis patients to reduce pain and distortion of joint have been done. Actually in America water exercise programs have been actively practiced for arthritis patients. However the study and practice of water exercise can not be found easily in Korea. Considering that the effectiveness of aqua exercise has been evidently confirmed, the exercise should be fully utilized. Under this circumstance, we provide basic data for aqua exercise program through the research on the needs of water exercise and characteristics of arthritis patients. Summerising the result of this study, the primary needs of aqua exercise is to get additional effect of medical treatment for the patients, especially unsatisfied patients to the medical treatment. The level of needs shows very high as of 57.3% of total sample. The strength of needs has relation to economic status and sociality. Hospitals and health centers should develop aqua exercise program not as a simple physical exercise but as a medical management for arthritis patients. Institutional base must be prepared for the patients, who have weak economic, physical and social ability, to easily access to the benificial exercise.

The import content of exports (ICE) is defined as the amount of foreign input embodied in one unit of export, and it has been used as a measure of the degree of integration into the global production network. In this paper, we suggest an alternative measure based on the decomposition of gross output and imports into the contributions of final demand terms. This measure considers the manner in which a country manages its domestic production base (gross output) and utilizes the foreign sector (imports) simultaneously and can thus be regarded as a more comprehensive measure than ICE. Korea's input-output tables in 1970-2018 are used in this paper. These tables were rearranged according to the same 26-industry classification so that these measures can be computed with time-series continuity and so that the results can be interpreted clearly. The results obtained in this paper are based on extended time-series data and are expected to be reliable and robust. The suggested indicators were applied to these tables, and, based on the results we conclude that the overall importance of the global economy in Korea's economic strategy has risen and that the degree of Korea's integration into the global production network increased over the entire period. This paper also shows that ICE incorrectly measures the movement of the degree of integration into the global production network in some periods.

1950년대 이후 선진공업국에서 나타난 탈 공업화 현상과 1970년대의 석유위기 이후의 경제위기에서 탈피하기 위한 대안 중 하나는 첨단 신산업을 중심으로 지역혁신을 유도하는 것이었다. 미국의 실리콘 밸리, 영국의 캠브리지 등은 체계적인 계획이나 정책적 노력 없이 혁신환경이 조성된 대표적인 예라고 할 때, 옥스퍼드 지역 역시 그에 버금가는 혁신지역이라 할 수 있다. 본 연구는 옥스퍼드 지역을 대상으로 지역혁신이 언제, 어떠한 방식으로 발생하였으며, 그러한 변화과정에 영향을 미치는 요소는 무엇인지, 혁신은 어떻게 시작되었는지 등을 규명하고자 한다. 본 연구는 여러 가지 문헌자료와 인터넷 포탈 등을 검색하고 현장답사를 통한 관계자, 전문가 면담 등을 통해 수집한 자료에 근거하여 이루어졌다.

Consumption and selling of Non Timber Forest Products (NTFPs) are important means to meet nutritional requirements and improve the socio-economic conditions of the rural population. The purpose of this study was to document the status and utilization pattern and assess the economic value of NTFPs sold in the markets of the Itanagar Capital Region (ICR) of Arunachal Pradesh. Five major markets with 182 vendors were surveyed, and a total of 94 plant-based products under 63 species belonging to 32 families were found to be sold in the markets. Species like Acmella oleracea, Clerodendrum glandulosum, Dioscorea alata, Houttuynia cordata, Phoebe goalparensis, Piper pedicellatum, Zanthoxylum rhetsa, etc. are found to be highly preferred and have a higher demand in the local markets. The edible products of species like Piper pedicellatum and Phoebe goalparensis though highly consumed in the study area, are used only within the region, and the national and international demands of the species are nil. The animal-base products are not included in the study.

Purpose: The development of natural batik dyes based on a combination of coconut fiber waste and avocado leaves using the extraction method is important to support the green economy and reduce chemical waste in Indonesia. Research design, data and methodology: The research explores the use of coconut fiber and avocado leaf waste extraction as a natural batik dye and conducts market testing to assess consumer satisfaction. Results: Indonesian batik exports are growing, but synthetic dye practices are causing a decline in demand. To address this, natural dyes are being explored, including coconut fiber waste and avocado leaf waste. Conclusion: Test results from washing at 40 degrees Celsius in terms of color changes and color staining, from sweat in terms of changes in acid color and changes in base color, to sunlight in terms of color fastness value, to heat to iron in terms of color change and color staining shows a value of 3-4 (quite good) and 4-5 (good), meaning that coconut fiber and avocado leaves waste can be used as natural batik dye.
