Polyglutamic acid(PGA) 함유량이 증대된 청국장이 조골세포에 미치는 영향을 세포 수준에서 관찰하고자 하였다. 조골세포에 미치는 영향을 관찰하기 위하여 세포 생존율, 염기성 인산분해효소(alkaline phosphatase, ALP) 활성, 골 석회화 형성능, 조골세포 분화 관련 유전자 발현능을 측정하였다. 세포 독성이 없는 농도에서 염기성 인산분해효소 활성을 측정한 결과 농도에 의존적으로 ALP 활성이 증가하였으며, 일반 청국장 A보다 PGA 함유량이 증가한 청국장 B가 더 높은 ALP 활성 증가 효과를 나타내었다. 청국장의 골 석회화 형성능을 측정한 결과 역시 청국장 A보다 B가 더 높은 석회화 형성능을 나타내었다. 또한 분화 관련 유전자인 OCN, OPN, Col1, ALP 역시 청국장 B가 A보다 유전자 발현이 더 높게 나타났다. 이러한 실험 결과를 바탕으로 PGA가 증대된 청국장이 기존 청국장보다 조골세포의 활성에 효과적일 것으로 생각한다.

This study has main purpose to understand the traditional house, not by outside researcher's but by inside dweller's view. The house in Geochang, is descendent house of Jeong-On who was faithful scholar at Chosen Dynasty. In order to understand, I restore firstly the house form and space at traditional era, 60 years ago, and every dwellers not only family members but also servants and guests, by interviewing old matriarch. One of the main rules of the house disposition is Ancester worshipping life. Worshipping floor of Anchae, main building, is located unusually in front of Shrine for Jeong-On, in order to connect all activities directly. Sarangchae, men's building, opened to the funeral mourners, is separated by a wall because women have to serve foods and wail at the backside. Space for everyday life is separated by man/woman, insider/outsider, master/subordinate. Agricultural production is also key factor of the space allocation: big storage buildings for rice crop needed to tenant farming. Both activities of ancestor worship ceremony and guest greeting need large kitchen annex area for food preparation and serving space of rear veranda floor. A number of guests visit the house: guest-greeting activity is taken place from the family pavilion, Neungheo-Jeong and Saranchae by the social position. This study show that architectural space and form of the house reflects exactly dwellers life.

Pilot study was conducted to examine the effects of ponded-water depth and reclaimed wastewater irrigation on paddy rice culture. For the ponded-water depth effect, three treatments of shallow, traditional, and deep water depths were applied, and each treatment was triplicated. The irrigation water for the treatment pots was an effluent from constructed wetland system for sewage treatment, while the control pot was irrigated with tap water kept traditional ponded-water depth. Irrigation water quantity varied with ponded-water depth as expected and drainage water quantity also varied similarly, which implies that shallow irrigation might save irrigation water and also reduce environmental impacts on downstream water quality. Rice growth and production were not significantly affected by ponded-water depth within the experimental condition, instead there was an indication of increased production in shallow and deep ponded-water depths compared to the traditional practice. Raising drainage outlet to the adequate height in paddy dike might be beneficial to save water resources within the paddy field. There was no adverse effect observed in reclaimed wastewater irrigation on the rice production, and mean yield was even greater than the control pots with tap water irrigation although statistically not significant. Water-saving irrigation by shallow ponded-water depth, raising the outlet height in diked rice paddy fields, minimizing forced surface drainage by well-planned irrigation, and reclaimed wastewater irrigation are suggested to save water and protect water quality. However, deviation from traditional farming practices might affect rice growth in long term, and therefore, further investigations are recommended before full scale application.

Background: The present study was intended to determine the prevalence and identification of species involved causing coccidiosis in broilers rearing under traditional farming system in Mirpur, Azad Kashmir, Pakistan. For the current study, a convenient sampling technique was carried out. A total of 7814 broilers (aged 1 to 6 weeks) were submitted to the Disease Diagnostic Laboratory of Livestock and Animal husbandry Department Mirpur, Azad Kashmir. Results: From the total screened, 750 were found positive for coccidiosis representing an overall prevalence of 9.59 %. Age-wise highest prevalence (10.88 %) recorded in the middle age birds (0 to 3 week old) were found more susceptible to infection than those aged above 3 weeks. Higher prevalence (12.49 %) of coccidiosis in broilers was observed in spring as compared with 6.60 % in summer season. In this study two main coccidiosis causing species, Emeria tenella and Emeria maxima were identified on the basis of their morphological feature and habitat (caeca and intestine), However, E. tenella was dominant compared to E. maxima. Conclusion: The study provides an insight to the occurrence of Emeria species which must be taken into consideration when rearing the broilers.

Since ancient times in Korea, in spite of the ranks of high and low, drink was like a all sorts of human emotions. In particular, the drought, or any weapon except when wages found the ball back to God or to buy a drink to celebrate the sixtieth birthday or marriage and feasting like mails, and the priests or the funeral, such as consciousness raising in this procedure. The country had strict rituals in ceremonial events were thereby is living up to deep. The history of the drink in the history of the past, given that the main grain farming culture has already begun since the era of gojoseon was launched remains to be seen. This has been a long history of traditional attention to clean up and organize the showing to the public hall is a nationally scarce in some areas of that era, or the facility is not large. Therefore, in this study, alcohol-related exhibits and Museum recognizes the reality of the future sake Museum architectural plans: the Foundation provides materials for that purpose.

During the late Chosun Dynasty, famine was the main cause of climate ecological background, such as frequent floods and droughts, the Little Ice Age (小氷期), and epidemic. In addition, it influenced the social and cultural background, such as failure toprovide Yiangbeop (移秧法), breakout of war and revolt, loss of farming cattle, grain consumption due to brewing, the concentration of wealth, and tenacity of shamanism. "Limwongyungjeji" "Injeji" of the last part had been written about the famine; wild plants to raw, dried, or dried powder, or processed pharmaceutical goods. Grain couldbe replaced in more than 330 types of famine relief food and recipes; 170 species of vegetables, 34 species of vegetation, and 33 kinds of fruit - the botanic foods were mainstream. Edible parts of these plant foods are those of 14 kinds: 175 species of leaves, 113 species of sprouts, 99 kinds of buds, and other fruits, roots, stems, flowers, etc. The recipe (poaching, salting, and oil-marinated) was written 186 times or forsoup, raw, and boiled.

When we consider changes in agro-fishery systems instigated by environmental changes in islands, rise in sea levels, and natural disasters such as tsunamis, there is an urgent need to carry out initiatives to enhance life standard and conserve ecosystem in island and coastal regions. To protect the region's landscape from the effects of climate change, it is necessary to develop an integrated management system for ecosystem conservation, human settlements, and the local economy. This paper discusses the outline of a preliminary national plan for a sustainable island management system for remote (inhabited and uninhabited) islands in Korea. Two main ideas to enhance life standard are adapting to the natural environment by applying traditional knowledge and utilizing ecological resources of islands, i.e., improving the quality of life and creating added value. As a technique for improving the quality of life, the establishment of eco-villages based on energy-efficient passive houses and ecological welfare is suggested. Another technique for creating added value, the development of sea-farming islands that utilize islands' new recyclable energy is also proposed. Finally, the suggested ideas are discussed in relation to island ecotourism and carbon zero islands.

Agriculture plays an industrial and economic role, as well as an environmental and ecological conservation role, group harmony and the inheritance of traditional culture. However, no matter how advanced the industry is, the basic food necessary for human life can only be produced through the photosynthesis of plants with natural resources such as the sun, water, and air. The Food and Agriculture Organization of the United Nations (FAO) predicts that the world's population will increase by another 2 billion people by 2050, and it faces a myriad of complex and diverse factors to consider, including climate change, food security concerns, and global ecosystems and political factors. In particular, in order to solve problems such as increasing productivity and production of agricultural products, improving quality, and saving energy, it is difficult to solve them with traditional farming methods. Recently, with the wind of the 4th industrial revolution, ICT convergence technology and artificial intelligence have been rapidly developing in many fields, but it is also true that the application of new technologies is somewhat delayed due to the unique characteristics of agriculture. However, in recent years, as ICT and artificial intelligence utilization technologies have been developed and applied by many researchers, a revolution is also taking place in agriculture. This paper summarizes the current state of research so far in four categories of agriculture, namely crop cultivation environment management, soil management, pest management, and irrigation management, and smart farm research data that has recently been actively developed around the world.

Most agriculture plantings are based on traditional farming and demand a lot of human work processes. In order to improve the efficiency as well as the productivity of their farms, modern agricultural technology was proven to be better than traditional practices. Internet of Things (IoT) is usually related in modern agriculture which provides the farmer with a real-time monitoring condition of their farm from anywhere and anytime. Therefore, the application of IoT with a sensor to measure and monitors the humidity and the temperature in the mushroom farm that can overcome this problem. This paper proposes an IoT based monitoring system forindoor Ganoderma lucidum cultivation at a minimal cost in terms of hardware resources and practicality. The results show that the data of temperature and humidity are changing depending on the weather and the preliminary experimental results demonstrated that all parameters of the system were optimized and successful to achieve the objective. In addition, the analysis results show that the quality of Ganoderma lucidum produced on the research method conforms to regulations in Vietnam.
