The purpose of this study is to analyze characteristics of literature on the residential environments of Korean-Chinese people residing in China. The number of such studies on residential environment is a total of 123, of which 86 (69.9%) are Korean studies and 37 (30.1%) are Chinese studies. Research has been conducted in China since the 1980s, but from 1990s onward, research was conducted in Korea following the establishment of diplomatic ties between the two nations. More studies related to history, society, and tradition have been conducted in China than Korea because China is a multiracial nation and Korean-Chinese people comprise an ethnic minority. In terms of residential environment, the majority of studies are related to architecture and space and are typically focused on villages and housing. Studies on traditional housing of the Korean-Chinese focus on general characteristics of traditional housing, targeting China's three northeast provinces and the Yanbian Korean Autonomous Prefecture of China. Studies on modern housing of the Korean-Chinese have mainly been conducted in Yanji City in China. The reason for this is that 41% of Yanji City's population is Korean-Chinese, a distinct difference can be seen between Yanji City and other areas regarding changes of modern housing, and ondol (the traditional Korean floor heating system) is commonly found in modern housing there.

Agricultural tourism is a new kind of industry, which combined agriculture with tourism. It not only has the productive function, but also has the function of improving the quality of ecological environment and supplying people with sightseeing, leisure, vacation. Agricultural tourism is a new kind of industry from the amalgamation of agriculture and tourism: it is based on farm work, characterized by agricultural management, combines agriculture and tourism, and includes the city as a market-place. It satisfies tourist demand with food, lodging, excursions, shopping and entertainment provided by agricultural places and agricultural products. After combining the substance of this study with the primary sources regarding the development of agricultural tourism, I suggest plans for the development of local agricultural tourism on the basis of sustainable tourism theory in case of the Inner Mongolia region. To conduct research, various data such as literature research and surveys are collected and analyzed. According to the result of the research, the Inner Mongolia region has great-wealthy resources for agricultural tourism. However, they have problems as well such as lack of funds, low infrastructure, low business-mind level, low management-mind, the scarcity of mid-supporting organizations for research and education, low awareness, and low service level of the agricultural tourism. In order to solve these problems, have to strengthen publicity, strengthen the county and city communication, educates continuously profession talented person, establish related laws and regulations, increase the integrity of infrastructure. As a developing industry, agricultural tourism is a new field of study which needs more encouraging research. The agricultural tourism of Inner Mongolia Autonomous Region has only just started development resulting in a limited amount of information available for this study. Future planned work entails a continuous in-depth study of Chinese agricultural tourism, considering Inner Mongolia Autonomous Region in particular.

In order to export Korean spray roses to the China, it is needed to analyse chinese preferences, rose attributes, and purchase intentions. The purpose of this study is to present the implications on the production and distribution of roses for export by analyzing the quality preference attributes and purchase intention of Korean rose for Chinese flower experts. A survey on the preference and purchase intention of Korean flower roses by Chinese flower experts was conducted through face - to - face interviews with flower show participants in China. Approximately 100 Chinese flower experts who participated in the Flower Show in 2016 received the questionnaire, and 86 survey results could be used for analysis. Survey data were analyzed using ordered probit and bivariate probit models. As a result of an analysis, it was found that Chinese flower experts were more likely to buy Korean roses than Chinese roses even if they consider flower color, leaf shape and size and color diversity. The probability of purchasing more than twice the price was higher than that of the color diversity considering the flower shape, leaf shape and size, but the bivariate order probit model was larger than that of flowers, leaves and size, and the order of probability size was changed. In order to increase the export of Korean spray roses to the Chinese market, We need to increase Chinese experts' preferences and satisfaction. For this purpose, it is very important to develop export varieties of roses with large flower buds and shape / coloring, and to apply the useful post-harvest technology that can extend freshness and distribution period of export roses.

Agricultural research and development (R&D) investment has contributed not only to agriculture but also to the overall economic growth of the country. The recent arrival of the fourth industrial revolution has raised the need for agricultural R&D as a preparation. Agriculture R&D is directly related to the fourth industrial revolution in the agricultural and livestock sectors that utilize big data, robots, artificial intelligence and cloud. Meanwhile, subsidies or grants are considered the most widely used means of policy. Therefore, in light of the current situation in which Chinese agriculture values R&D investment, this study attempted to analyze the dynamic relationship between variables by establishing a model of agricultural environment subsidy representing the role of government, agricultural technology progress representing existing agricultural R&D investment, agricultural income representing agricultural development and total agricultural output. The analysis results showed that each variable's reaction to the rise in China's agricultural R&D investment has a positive effect on agricultural development, in line with the theory that the investment in science and technology in the agricultural sector has a positive effect. In addition, the response of each variable to China's rising agricultural environment subsidy is shown to have a positive relationship, which can also be said to be in line with the theory that the government's market-friendly intervention is beneficial to economic development.

과거 한국의 식품 오염원 중 법적인 규제 등을 통해 구체적인 통제가 이루어지지 못하고 있는 것이 축산물의 항생제로 알려져 항생제 오 남용으로 인한 내성균의 출현으로 비상이 걸렸던 적이 있었다. 요즘은 항생제를 지나치게 많이 사용해 가축이나 인체 내의 병원성 미생물들이 내성이 생겨 문제가 되고 있어 2011년 7월부터 가축용 사료에 항생제 첨가가 금지하게 된다. 한국은 항생제 내성률 1위로, 2000년 세계보건기구(WHO)에 따르면 대표적 항생제인 페니실린에 대한 폐렴구균의 내성률이 70%로 세계 1위이다. 어느 보고서에 따르면, 축산물 1톤을 생산하는 데 사용되는 항생제가 스웨덴이나 뉴질랜드, 덴마크 등 축산 선진국이 31~44g에 불과한데 비해 한국은 911g에 이른다. 투여 경로는 배합사료에 포함된 양이 54%, 농가의 임의 치료가 40%, 수의사 처방은 겨우 6% 순으로 나타났다. 그러나 OECD 회원국 중 수의사 처방 없이 항생제의 임의 투여를 허용하고 있는 나라는 한국뿐이다. 세계보건기구(WHO)에서는 가축사료에 항생제를 첨가하지 말 것을 권장하고 있으며, 유럽연합(EU)도 항생제는 반드시 수의사의 처방에 의해서만 사용토록 제한하고 있다. 최근 국립수의과학검역원에 의하면, 축산용 항생제 사용량이 2008년에 비해 18%, 2001년에 l해 무려 38%가 감소되었으며, 이중 닭은 20%, 소의 항생제 사용량은 36%가 감소하였다고 밝혔다. 사육 가축들의 항생제 오남용을 줄이기 위해서는 사료에 첨가하는 항생제나 성장호르몬, 비소 투여 등의 투여 대신에 미생물 생균사료나 녹차사료, 한약재사료 등의 천연면역물질을 함유한 사료를 먹여 스트레스를 덜 받고 면역력 증강에 좋은 사료를 먹여 키운 건강한 가축으로 생산한 육류는 맛도 특별히 좋다. 본 자료의 대부분은 금년부터 3년간 농촌진흥청 국립축산과학원과 중국청도농업대학과 "고품질 축산물생산을 위한 중약제를 이용한 질병방지체제 연구"라는 과제로 공동협력연구를 수행하게 됨에 따라 지난 11월 4일부터 10일까지 필자가 중국 청도농업대학을 방문하여 세미나시 발표한 자료임을 밝혀두며, 국내 수의학 연구에도 도움이 되고 저 소개한다.

The heading responses of rice varieties that originated from South Korea, North Korea, and northern China were examined under the temperature and day-length conditions of 13 major rice production areas in North Korea. Kenjiandao3 and Nongdae3 originated from China, Olbyeo1, Olbyeo2 and Sonbong9 from North Korea, and Joun from South Korea demonstrated the earliest heading stage depending on the regional environment. Out of 40 rice varieties, 34 reached the heading stage within the regional safe marginal heading date (SMHD) under Haeju and Sariwon environmental conditions, while 16 to 17 varieties reached the heading stage under Wonsan, Changjon, Supung, and Yongyon environmental conditions. Some middle and mid-late maturing varieties that originated from South Korea reached the heading stage within the SMHD under the temperature and day-length conditions of Kaesong, Haeju, Sariwon, Nampo, and Pyongyang that are located in the west-southern plain. The majority of early maturing varieties, but not the middle or mid-late ones, reached the heading stage within the SMHD under the environmental conditions of Singye, Anju, Kusong, and Sinuiju. Only a few early maturing varieties demonstrated the heading stage within the SMHD under Yongyon, Changjon, and Wonsan environments. The number of days to heading was highly positively correlated among all regions; however, it was not consistent among the rice varieties. The 40 rice varieties that had been tested were classified into seven groups according to their heading responses to the temperature and day-length variations of the 13 regional conditions at 65% similarity level in cluster analysis.

We investigated the basic vegetative phase (BVP), photoperiod-sensitivity (PS), and thermo-sensitivity (TS) of 40 rice varieties to characterize their heading ecology that is adaptable to North Korean rice production areas. The ranges were 12 - 43 days for BVP, 0 - 74 days for PS, and 15 - 33 days for TS, depending on the variety. The number of days from transplanting to the heading stage (DTH) was significantly correlated with PS in the 13 major rice production regions where all 40 varieties (including early-, middle-, and mid-late-maturing varieties) were tested. DTH was significantly correlated with BVP and TS but not with PS in the 10 low-temperature regions where only 28 early-maturing varieties were tested. The heading ecology of the adaptable varieties for each region could be characterized by an exponential equation between the BVP and PS of varieties that headed at the border of the safe marginal heading date (SMHD) for each of the seven regional environments (Kaesong, Haeju, Yongyon, Singye, Sariwon, Nampo, and Pyongyang). A PS of 25 - 30 days or less was an additional adaptive trait in the Sariwon and Pyongyang environments. The varieties that reached the heading stage not later than the SMHD in six regional environments (Anju, Kusong, Sinuiju, Changjon, Wonsan, and Supung) and those that reached the heading stage not later than the late marginal heading date (LMHD) in four regional environments (Hamhung, Pyonggang, Huichon, and Kanggye) had both a PS of 26 days or less and a BVP of 25 - 28 days or less. In the Yangdok, Sinpo, and Chunggang environments, varieties that reached the heading stage not later than the LMHD for each region had a BVP of 15 - 20 days or less. The results suggested that a shortened BVP trait should be introduced to existing early-maturing rice varieties to reduce the duration of growth period to reach the heading stage.

This study was conducted to determine the effects of increasing the dietary levels of conjugated linoleic acid (CLA) which is produced from bio diesel by-products, on milk yield, milk composition, and blood metabolites of mid-lactating dairy cows. A total of 20 mid-lactating dairy cows ($631{\pm}25.0kg$) were assigned to one of four treatment groups and fed twice daily an equal amount of a basal diet ($NE_L$ 32 Mcal/d, CP 17%) contained 12kg/d of concentrate, 15kg/d of corn silage and 4kg/d of the hay mixture (tall fescue+orchard grass). Conjugated linoleic acid were fed for 2 weeks of adaptation periods and 4 weeks of collection periods at 0 (Control), 50 (T1), 100 (T2) and 150g/d (T3), respectively. By the increases of dietary CLA supplementation, milk yield and 4% fat corrected milk increased, whereas milk fat content decreased (p<0.05). The concentrations of stearic acid and oleic acid decreased with increasing dietary CLA supplementation, while the concentrations of total CLA increased (p<0.05). In conclusion, this study shown that the supplementation of dietary CLA manufactured from bio diesel by-products could improve milk yield and CLA concentrations of milk in mid-lactating dairy cows.

Neuroinflammation is mediated by the activation of microglia and has been implicated in the pathogenesis of neurodegenerative disorders, such as Alzheimer's disease and Parkinson's disease. Therefore, the inhibition of neuroinflammation may be an effective solution to treat these brain disorders. Protaetia brevitarsis seulensis is an insect belonging to the order Coleoptera and inhabits Korea, China, Japan and Siberia. P. brevitarsis seulensis is an edible insect that can be consumed as a protein source for humans. It has been reported that P. brevitarsis seulensis contains useful bioactive substances for hepatoprotection and improving blood circulation, such as indole alkaloids. Microglia cells are the main source of proinflammatory cytokines and nitric oxide (NO) in the central nervous system, which Perform neuroimmune, inflammatory, and other neurobilogical functions. In this study, we investigated the anti-neuroinflammatory effects of P. brevitarsis seulensis ethanol extract (PBE) in activated microglia cells treated with lipopolysaccgarude (LPS, 100 ng/ml). As a result, PBE significantly inhibited NO production without cytotoxicity and decreased the expression levels of inducible NO synthase and cyclooxygenase-2. In addition, the production of inflammatory cytokine secreted by LPS was also reduced by PBE. These results suggest that PBE could be a good source of functional substances to prevent neuroinflammation and neurodegenerative diseases.
