  • Aralia elata is found in mountain areas all over Korean peninsula. Aralia elata is the scientific name for Japanese angelica tree. The tree belongs to the family Araliaceae, commonly known as ginseng family. Bud sprouts from apical shoot tip of the plants are rich in flavor and thus mainly used for both folk medicine and vegetable. The stalks with apical buds are gathered in the early spring and planted in sandy soil or water in the greenhouse. The sprouting buds are then collected and sold as fresh vegetable. Although the plants have been used for food, they have been cultivated in a very small scale. In spring, local farmers just go around mountain areas to search the trees and gather the stalks as much as they get and sell them to the market. No conservation efforts have been made to stop the exploitation or to save the dwindling population. We tried to provide local farmers with the plants that may be used as an alternative to stalks from wild populations. This will hel! p conserve the wild populations. However, it is hard to propagate them either by conventional cuttings or by seed germination in a short period of time. Mass propagation using tissue culture systems have shown a great promise with several woody plants. Recently we developed a mass propagation technique via somatic embryogenesis system using mature and/ or juvenile explants for Aralia elata. Several factors affecting somatic embryogenesis system including SE(somatic embryo) induction, embryogenic callus proliferation, SE germination, plant regeneration and transplanting to field will be presented. And some problems arising for the somatic embryogenesis system will be also discussed.lso discussed.

  • Pharmaceutical technology has primarily focused on the development of the best dosage forms depending on the route of administration. The design of dosage forms is greatly influenced by the route of administration. Due to a variety of advantages such as avoidance of first-pass effect, abundant blood supply and easy access to the absorption site, the oral cavity has frequently been selected as a site for drug delivery. Since the oral cavity is relatively unique from the anatomical and physiological viewpoint, one should always consider these conditions when designing the drug delivery systems for the oral cavity. In this regard, the current review paper was prepared to summarize the essential features of the drug delivery systems utilized in the oral cavity, along with the introduction of various dosage forms developed to date.

  • β amyloid protein (Aβ) plays a critical role in the pathogenesis of Alzheimer's disease (AD) and possibly in Aβ-induced mitochondrial dysfunction and oxidative stress. Aβ can directly cause reactive oxygen species (ROS) production. Overproduction of ROS is considered to be involved in the pathogenesis of neurodegeneration of AD. Here, we investigated 9 kinds of ramie (Boehmeria nivea, (L.) Gaud., BN; hereafter denoted as BN) for their protective action against oxidative stress in a cellular system using C6 glial cells. We observed loss of cell viability and high levels of ROS generation after treatment with hydrogen peroxide (H2O2) and Aβ25-35. However, treatments with BN extracts led to an increase in cell viability and decrease in ROS production induced by H2O2 and Aβ25-35. In particular, the extracts of BN-01 (seobang variety from Seocheon) and BN-09 (local variety from Yeonggwang) showed excellent anti-oxidative properties. This indicates that BN extracts could prevent neurodegeneration by reducing oxidative stress in cells.

  • The initiative to determine farmland use has been transferred to local side under the decentralized government system in Korea. New Land Act and Rural Development Act support it. Changes in external and internal environments of Korean agriculture require to diversify farmland use. Lpcal development plan may be implemented when specific farmland use plan is prepared. However, (armland use planning has not been prepared by the local governments yet. This study aims to identify problems encountered in current farmland use and suggest directions of effective and reasonable farmland use planning relevant to local conditions. Questionnaire method was used to prove topographical differences of community land demand, Statistical analyses show that farmers desire to utilize marginal farmland for income increase. Growing grass(42.0%) and cash crops(41.7%) was greatly demanded by them. They were generally eager for developing touristic farm (52.1 % ). By topographical characteristics, the eager was greatest in coastal areas, on the contrary, it was relatively low in mountainous areas. There were more farmers who want to expand their farmland in rice farming(48.4%) or rice-horticulture farming(46.9%) areas. Potential retirer among farmers were most in suburban areas, However, it was expected that there would be the highest retirement rate in rice farming areas because of the high rate of aged farmers. Farmland use planning should be incorporated into food production policies and community people's needs for income increase and life improvement. Agriculture promotion areas must be maintained for scale optimized farming and cash crop farming as much as possible. However, minimum portion for other uses in each village or farming community unit should be adopted. Less favored areas will have to be utilized for both agriculture and non-agriculture uses. Priority can be put into touristic resorts as a non-agriculture use. Furthermore, such areas can be used for sustainable agriculture as well as for residence, industry, animal breeding.

  • Ecosystem services play a role in promoting sustainable development by contributing to human welfare. For sustainable development, a balance between supply and demand for ecosystem services must be made. In this regard, in this study, factor analysis was performed using the results of measuring ecosystem services for the supply of ecosystem services and national statistical data representing socio-economic factors for demand for ecosystem services The results of analysis for Gyeong-gi Province are as follows. The service supply based on the result of ecosystem services was divided into the mixed service provisioning as factor1, the food provisioning as factor2, and the P retention service provisioning area as factor3. As for the demand for services based on socio-economic factors, factor1 is divided into urbanized areas, factor2 is forest development area, and factor3 is agricultural activity development area. Local governments that maintain balance were evaluated as Pocheon, Yangpyeong, Icheon, Pyeongtaek, Goyang, Suwon, Gwangmyeong, and Osan, and imbalanced local governments appeared in Gimpo, Uiwang, Anseong, and Yeoju. A management plan to maintain the balance between supply and demand of ecosystem services was suggested. The analysis method and results of this study are expected to be applicable to various local governments through regional expansion.

  • This thesis, which involves honest life stories of members of the ìtraditionalî Korean generation that lived through the turbulent times of the first half of the twentieth century, assesses the meaning and import of Korean cuisine during an individual Korean's lifetime, as well as the relevant properties of the culinary culture of the traditional generation and how those properties continue to influence the present generation of Koreans. Thus, traditional Korean culinary culture was subdivided into the following four aspects, each of which were exemplified by representative examples. The first of these is slow-food dietary life, which is exemplified by fermented foods. The development of side dishes (panchan) based on fermentation - kimchi, different types of soy and bean paste, salted seafoods, dishes of dried radish or cucumber slices seasoned with soy sauce, and so on - made the quantitative and qualitative supplementation of food possible for traditional Koreans. The second of these aspects, referred to as friendly dietary life, is exemplified by self-sufficiently produced foods. The system of many species and small production suitable with the season made it possible to produce food from sustainable ecological systems and to maintain locally grown food-cultures, each of which was distinguished from others by a local specialty product. The third aspect of the traditional Korean culinary culture involves the same use of medicinal roots and plant materials for foodstuff, and this is exemplified by the use of foods to cure and prevent diseases. The notion, for example, that 'boiled rice is an invigorant' is characteristic of the notion that diet can function in a preventative medical context, and other similar Korean notions illustrate the importance, also, of the curative properties of food. The fourth and final aspect of traditional Korean culinary culture identified herein is creative dietary life, which can be viewed essentially as a Korean adaptation to the turbulence of life during the early $20^{th}$ century in Korea. This trend is exemplified by many Korean foods that were created in response to foreign influences, such as onions, cabbages, curry, etc. which found their place in overall Korean culture through the age of Japanese settlement, as well as the Korean war.

  • Purpose - As the competition in the foodservice franchise industry and the market becomes fierce and the entry barrier is lowered, the foodservice franchisor and franchisees strive to increase their competitive advantage in the market. Therefore, the franchisor and franchisees use experience management strategies to enhance the positive experiences of customers visiting the stores. In this regard, this study examines the effects of customer-oriented activities (physical-, social-, health-, and service-oriented activities) on utilitarian and hedonic values, and loyalty using stimulus-organism-response (S-O-R) model and value-expectancy theory. Research design, data, methodology - The data were collected from panels of online survey company, who visited a foodservice franchisee within last month. The survey was conducted for about 15 days from March 7, 2019 to March 21, 2019, and about 3,500 e-mails and messages were distributed to ask for the survey. A total 412 responded and completed the questionnaires. Of the 412 completed questionaires, 12 were discarded due to missing and misinformation data and 400 were retained for further data analysis. Results --The results showed that social oriented activities, health oriented activities, and service oriented activities had positive effects on hedonic value, while physical oriented activities did not have a significant effect on hedonic value. Health oriented activities and service oriented activities had positive effects on utilitarian value, while physical oriented activities and social oriented activities had no significant effects on utilitarian value. Hedonic and utilitarian values also have a positive effect on loyalty. Conclusions - First, food service franchises should provide services and menus in consideration of the health of customers. When a customer visits the store, franchisee should provide more health-oriented food or materials and clean and comfortable conditions so as not to threaten the health of the customer. Second, the food service franchise must build a service-oriented system. Foodservice franchisor need to provide continuous service training not only to the franchisees, but also to the employees of the franchisees. Third, franchise should design a store where customers can form social exchanges through providing various information exchange to customers and making the store as a local community center.

  • Over the last three decades, Korean farming system has been directed to maximum agricultural production and to increase farmer's income through adoption of high-yielding crop varieties and high input of agrochemicals . These farming practices have resulted in problems of water-quality deterioration, soil degradation , and food safety. At present, over 40 million tones of animal waste are bing produced annually, which amounts to disposing the waste at the annual rate of 20 tones per ha in the total area of farming land in Korea. Nearly a half of total available water resources is used as irrigation water predominantly for rice paddy field. Thus, non-point source contamination of the water resources has been linked to agriculture across the nation. However, the extent to which agriculture contributes to the water quality is not fully known. Recently, Korean government provided various institutional measures to reduce the negative impacts of agricultural practices on the environ ental quality, and the Agricultural Environment Act was also passed by the legislature in 1998 and became effective January 1999. This Act does not cover the broad spectrum of the sustainable agriculture ; thus, the limited incentives within this Act are arguably ineffective to control the non-point source pollution. Recently new bulk blending of fertilizers(BB fertilizer) are bing produced (100, 000 tones in 1998) with Government subsidies. The BB fertilizers are to balance N-P-K ratio in the soils . Although the use of the BB fertilizers are encouraged with Government subsidies, non-point source pollution is still serious and will become worse. Precision farming is regarded as a new means for sustainable agriculture. It is a new technology that modifies the existing techniques and incorporates new one such as GIS, GPS , differential applicator to produce a new set of tools for the farmer to use. Precision farming, however, has constraints for individual farming practices. For exam le , farm size or parcel unit of each farmer is too small to adopt the precision agriculture on farmhouse-hold bases and farmer's ability to adopt the new technology is limited. However, it would be appropriate to establish local or regional cooperatives to operate such a precision farming system. It is recommended that Government provide sufficient incentives to help establish local and/or regional cooperatives.

  • Governments around the world place great hopes in innovation in their search for new sources of growth and for responses to grand challenges, such as climate change, new or re-emerging infectious diseases, accelerating urbanisation, ageing, food security, and availability of clean water. However they must devise their relevant support policies -- including through sponsored research within public research institutes -- taking into account that innovation processes are currently undergoing a major transformation. New innovation patterns include a broadening scope of relevant activities, a growing importance but changing nature of scientific roots of technological development, a stronger demand-pull, the emergence of new local and national STI powerhouses, and the rise of more open and globalised innovation networks. They translate into new opportunities but also constraints for policies to enhance the contribution of public research institutes to national innovation performance. The article derives the main policy implications regarding the desirable evolution of the mission, research focus, as well as the funding and steering of public research institutes, with a special reference to Korea.
