Objectives: This study aims to identify gaps between knowledge regarding migration and the spread of HIV/AIDS, to improve understanding of migrants with HIV/AIDS and their human rights, and to make suggestions for Korean policy makers to reform laws and policies towards granting migrants with HIV/AIDS more human rights and access to treatment and care. Methods: This study is based on an extensive literature review, questionnaire surveys and in-depth interviews from randomly selected 8 countries from 5 different continents: Japan from Asia; Australia from Oceania; Finland, Germany, Ireland and United Kingdom(UK) from Europe; and Canada and United States of America(USA) in North America. Results: This study has found that Korea has a discriminating policy regarding HIV/AIDS and foreigners. Classifying HIV/AIDS into a legal communicable disease, it requires a presentation of HIV/AIDS test results from foreigners wanting a long-term stay before entering. In principle, foreigners with HIV/AIDS cannot either enter or stay in Korea. If they are known infected with HIV/AIDS by any reason, they became to face an immediate deportation regardless of their sojourn statuses and purposes. Conclusion: With the results, this study suggests three reasons why Korean government needs to change the current HIV/AIDS policy on foreigners: 1) HIV-related travel restrictions have no public health justification, 2) its strict HIV/AIDS policy on foreigners could result in restriction on the mobility and migration of its people by the other countries, inversely, and 3) it needs to meet international guidelines and to observe conventions that international organizations suggest to maintain its status as a member of the international society.

The world dairy industry has been driving their dairy policy on the basis of the self-supportihg principle. With progressing the GATT negotiation, the objective production amount has been reduced to maintain the optimum level, which decreasing the extra supply and over-stock before the U.R talks. The Oceania countries, where has the price competition capability, are continually increasing the milk production amount. Even through the USA is trying to increase their production amount with new export policy, the U.S.S.R collapse-down caused to decrease the milk production in world-wide basis. Because the U.S.S.R produced the highest amount of milk in the world. Moreover Europe Union countries, which recorded the half amount of dairy products in the world was decreasing their milk production. Therefore, about 4% of shortage is encountering at major dairy production countries in the standpoint of supply and demand. The drastic increasement of foreign dairy product import affects the domestic dairy industry with raw milk replacement and new dairy food demands creation since 1995, the initial period of free import system. Now, the domestic dairy industry are facing the inevitable problems such as the correction of producting and processing system. First of all, our dairy industry should resettle down the dairy production structure on the basis of self-supply of raw milk and offer the accurate dairy food informations. We still need to improve the raw milk quality. Also, more efforts are needed to have proper raw milk price policy. General domestic policies including the settlement of raw milk supply and demand, the reliability of inspection system in raw milk, ideal raw milk price system, centralization of raw milk collection, specially separated dairy organization should be improved legally in our dairy industry.

In June 2011, walnuts (Juglans regia) from orchards in Kimcheon and Muan, in southern Korea, were found to exhibit downy mildew-like symptoms of a foliar disease. Whitish polygonal efflorescence was produced on the abaxial surface of affected leaves and discolored light green blotches on the corresponding adaxial surfaces. In the later stage of disease development, diseased tissues collapsed and became necrotic. Based on morphological and cultural characteristics, the causal fungus was identified as Microstroma juglandis. The sequence of ITS rDNA of the present isolate showed 100% similarity with those of M. juglandis obtained from GenBank databases, thus confirming its identity. Pathogenicity tests were conducted on leaves of walnut seedlings, fulfilling Koch's postulates. The disease has been previously reported in North America, Europe, Oceania and some western Asia. This is the first report of downy leaf spot on walnuts in East Asia.

There are approximately 250,000 organic livestock farming in the world. The total retail value of organic food sales in the world is $ 27 billion. The organic livestock products such as milk, lamb and beef are marketed mostly in Europe and the USA. The market share of organic food is about 2% in total food marketing value of worldwide and of the organic food marketing value, organic livestock products portioned 17% in the USA. The organic livestock products are primarily marketed at Supermarket(Europe), Health and Natural Food store(USA). Concerning international trade, it is very little. But it is increasing among the developed counties of Europe. In the future, the production of organic livestock products will be rapidly increased in South America, Middle East and Oceania, but the growth rate will be limited due to its expensive price, lack of marketing-infra and different regulation system. Most of developed countries drive organic farming policy strongly as the strategic means of rural development, diversifying agriculture system and environmental improvement.

Recently, interests in indoor air quality (IAQ) have been increased; however, a number of researchers have mainly focused on anthropogenic volatile organic compounds (AVOC) emitted from building materials. Therefore, the properties of natural VOC (NVOC) and anthropogenic VOC (AVOC) emitted from wood-based panels was investigated in this work. VOCs emitted from these panels were sampled through Tenax TA/Cabotrap and analyzed by GC-MS and GC-FID. Comparisons were made concerning TVOC, NVOC, and composition ratios of NVOC. It was revealed that TVOC emission rates of midium density fiber (MDF) were the highest. Besides, it was found that emissions of NVOC from wood-based panels were much higher than those of anthropogenic AVOC except for plywood of Oceania timber. It was also observed that the composition ratio of NVOC emitted from plywood of Pinus radiata was the highest as 65% of TVOC. Major NVOC components were monoterpene compounds such as $\alpha$-pinene, $\beta$-pinene, d-limonene, camphene and $\alpha$-terpinene. It was concluded that the composition rates of VOCs emitted from building materials were clearly different according to the raw materials and manufacturing methods.

To investigate the image, preference, importance and satisfaction of foreign visitors to Korean foods, 220 visitors (male 104, female 115) were surveyed with questionnaires in English and Japanese. To achieve this research purpose, frequency analysis, exploratory factor analysis, t-test, and one way ANOVA was performed using the SPSS 15.0 program. Subjects had various nationality such as Europe/Oceania (24.7%/), Asia (23.3%), Africa (12.8), and North America (39.3). The representative food was kimchi > bibimbop > bulgogi but the most favorite food was bibimbop > kalbi > bulgogi in order. Like this, there are some discrepancies among the food choice, especially in kimchi, so the taste of kimchi should be improved according to the foreigners' taste. The results of the preference about the image get the high grade from those factors; the resonable price of Korean food, the spicy taste, various kinds of food according to the settings of the table, good for the health with excellent taste. Foreigners consider that the cleanliness of food and tableware, the sanitation of the restaurants, the taste of the food and freshness of ingredients are the important factors in Korean food and Korean restaurants. According to these factors, the satisfaction is affected by the attitude of servers > the taste of the food > the freshness of the ingredients > the amount of the food > the atmosphere of the restaurants > the cleanliness of the tableware in order. From the relationship between the importance and the satisfaction, the low grade food should improve the color and styling of the food and be served the appropriate amount of the food. Moreover, it is needed to improve the combining the spices and the ingredients to maintain a balance between strong and delicate flavors and with this, Korean food should be more globalized to promote the development of Korea tourism.

In this study, we analyzed high-performance building technologies through a case study of 65 high-performance buildings in the U.S., Europe, Asia and Oceania. In detail, we reviewed the international trend of building energy-saving technology and energy consumption per unit area by analyzing buildings constructed within a 10 year period(2008-018). The primary energy consumption was $48-440kWh/m^2$, and the average value was calculated as $169.3kWh/m^2$. Although some buildings received high certification ratings, they did not meet either Korean or international energy evaluation standards. The system analysis revealed that many energy-saving technologies show various application rates in different countries because the technologies possess different properties. Furthermore, small-area building groups tended to have less primary energy consumption than the medium and large-area buildings, but the area-energy relationship $R^2$ value was analyzed as 0.3161, indicating no clear proportional relationship. Therefore, we propose that it is necessary to maximize the energy savings of buildings by taking into consideration a region's code, climate, building usage, area and space-using patterns to reduce energy and greenhouse gas emissions.

We found Urtica dioica L., an unrecorded alien plant, in the Han River basin of Korea. U. dioica is considered to be native to Europe, much of temperate Asia and western North Africa. This plant has been introduced to many other parts of the world. In Particularly, it reported as an invasive species from East Asia (Japan), Oceania and South America. This species is distinguished from related Korean taxa of the genus by its unisexual flower and dioecious plant species. In the Neighbor-Joining tree, U. dioica samples from the Han River Park (Sangam-dong, Mapo-gu, Seoul) and Yangjaecheon Stream (Daechi-dong, Gangnam-gu, Seoul) clustered into a clade consisting of a U. dioica s.s. Here, we provide a precise description, illustrations, a key to the related taxa, and photographs of its habitat.

Concrete-encased steel (CES) beam, in which structural steel is encased in a reinforced concrete (RC) section, is widely applied in high-rise buildings as transfer beams due to its high load-carrying capacity, great stiffness, and good durability. However, these CES beams are prone to shear failure because of the low shear span-to-depth ratio and the heavy load. Due to the high load-carrying capacity and the brittle failure process of the shear failure, the accurate strength prediction of CES beams significantly influences the assessment of structural safety. In current design codes, design formulas for predicting the shear strength of CES beams are based on the so-called "superposition method". This method indicates that the shear strength of CES beams can be obtained by superposing the shear strengths of the RC part and the steel shape. Nevertheless, in some cases, this method yields errors on the unsafe side because the shear strengths of these two parts cannot be achieved simultaneously. This paper clarifies the conditions at which the superposition method does not hold true, and the shear strength of CES beams is investigated using a compatible truss-arch model. Considering the deformation compatibility between the steel shape and the RC part, the method to obtain the shear strength of CES beams is proposed. Finally, the proposed model is compared with other calculation methods from codes AISC 360 (USA, North America), Eurocode 4 (Europe), YB 9082 (China, Asia), JGJ 138 (China, Asia), and AS/NZS 2327 (Australia/New Zealand, Oceania) using the available test data consisting of 45 CES beams. The results indicate that the proposed model can predict the shear strength of CES beams with sufficient accuracy and safety. Without considering the deformation compatibility, the calculation methods from the codes AISC 360, Eurocode 4, YB 9082, JGJ 138, and AS/NZS 2327 lead to excessively conservative or unsafe predictions.
