At the same time the unique cultural traits of each country are valued, it has become an essential element to establish the cultural identity of a country. This study is aimed at comparing the residence architectural cultures in East-Asia and thus identifying Korea's own unique traits by determining the application characteristics of traditional architectures of Korea, China and Japan through practical investigation of materials, a basic element of architectural shaping. Literature survey and field study were conducted in parallel for this study, and architectural buildings under investigation included Mucheomdang House in Korea, Prince Gong Mansion in China and Dokyudo Building in Japan. Construction materials in Korea, China and Japan include natural materials such as wood, stone and clay, and artificial materials such as metals, paper, roof tiles, plug and glass. and the buildings were constructed with the combination of these materials. This commonality can be often found in the architectural composition. However, in the interior composition, the choice and application of different materials were clear between three countries, which were shown to be different depending on climates, processing methods and living culture of each country. First of all, since each country selected materials under the influence of its own vegetation and climates, living environment of each country could be seen via its residence. Also, it could be seen that while Korea and Japan show a certain similarity such as the traits of standing-sitting culture and the finish of paper in the interior, China is clearly different. In particular, regarding the material processing, the artificial processing was minimized in Korea, which mainly gave rough and crude feelings while due to the use of straight timbers, the architectural representation with organized and refined feelings was made in Japan. China showed the highest percentage of artificial processing of materials among three countries, which was highly associated with the coloring culture of China. Also, it could be seen that technology related to fine architectural materials such as bricks and glass was greatly advanced in China. Thus, how immaterial elements such as natural characteristics, functionality and aesthetics were applied in relation to residence in Korea, Japan and China could be determined through the comparison of architectural materials.

This study examines the current alcohol use situation among adolescents and provides information relevant to development of adequate prevention programs for adolescent alcohol use in Korea. In this study, we used focus group research method and analyzed the outcome with constant comparison method. We classified 4 major categories of adolescent alcohol use situation such as the factors on enhancing alcohol use, the factors on delaying alcohol use, the occasions significantly related to alcohol use and the first alcohol use experience of adolescent. And we found out 16 minor categories and 93 concepts under the major categories. The results from the study revealed that the factors on enhancing alcohol use were associated with adolescents' psychological reasons, their positive perceptions on alcohol, family factors, peer influences, teacher's influences and social and cultural aspects on alcohol in general. The factors on delaying alcohol use were associated with health conditions, their negative perceptions on alcohol, parental monitoring, economic reasons and their limited access to purchase alcohol. The occasions significantly related to adolescent alcohol use were family events, school events and peer gatherings. In addition, the first adolescent alcohol use experience was strongly associated with the peer influences and significant adults' offer of alcohol. Findings suggest recommendations for prevention and intervention programs for adolescent alcohol use in Korea.

The purpose of this study is to figure out and establish the basic data that can help improve management of oral healthcare for the international marriage migrantwomen. In this sense, we surveyed questions on 237 women out of 1,300 immigrant women, who have participated the program in operation by multi-cultural household supporting center, in a fashion of face-to-face investigation and on-the-spot direct cavity inspection simultaneously from May 1th to October 31th, 2010. Collected data were electro-statistically computerized under SPSS 17.0 program and analyzed with frequency analysis, recurrence analysis and logistic regression analysis respectively. Foundings were revealed as follows; On the nationality base, show the data in the ratio of 38.8% for Vietnamese, 29.1% for Philippine, 12.2% for Chinese and 6.8% for Japanese respectively. Current oral cavity status shows in the ratio of 60% with carious tooth symptoms, 40% without carious tooth symptom. Philippine women have irregular sets of tooth in many a case. (i.e., in short of numbers of teeth, due to removing individual tooth.) Japanese ladies are indicated to have less irregular sets of tooth, in comparison with that of the other immigrants from overseas. And lastly, high-income immigrant women in general were found having less numbers of unhealthy sets of tooth. Getting older, it appears that decayed tooth symptom is on the tendency of getting less in the field of dentistry circles. Immigrant ladies living with husbands under higher education background usually are found living a life in the less ratio of having toothache. A full-time immigrant housewives, however, are living everyday life in more times of suffering with tooth disease.

As a result of conducting a cultural experiment of tomato using chicken feather protein hydrolysate (CPH) which was mass produced by keratin protein degrading bacterium Chryseobacterium sp. FBF-7 (KACC 91463P), we found that the stem and the root of tomato showed significant improvement in growth. For the purpose of phylogenic interpretation, a comparison was drawn between the effect of CPH, a treated CPH and untreated, on the changes of bacterial populations by 454 pyrosequencing based on 16S rRNA gene sequences. Tomato rhizosphere soil untreated with CPH (NCPH) showed 6.54 Shannon index from 3,281 sequence reads, and the rhizosphere soil treated with CPH (TCPH) showed 6.33 Shannon index from 2,167 sequence reads, displaying that it does not affect the diversity. Bacterial populations were composed of 19 phyla in the rhizosphere soil, and the phylum Proteobacteria occupied 40% of total bacterial populations. Bradyrhizobium, Agromonas, Nitrobacter, and Afipia (BANA group) which belong to Bradyrhizobiaceae were abundant and commonly detected in both the treated and untreated soils, suggesting the dominance of bacterial group in rhizosphere soil. The results obtained showed that CPH treatment does not affect the indigenous bacterial populations present in the rhizosphere soil.

Baekdudaegan Mountain System (BDMS) is a unique and traditional concept in Korea that puts importance on the connectivity of energy when Korean people recognize their mountain system. Two main national organizations that are in charge of managing natural environment in Korea, Korea Forest Service (KFS) and Ministry of Environment (MoE), have been independently investigating the natural resources in protected areas of BDMS. Each organization released its first survey report for the whole protected areas in 2011. In order to provide better understanding of BDMS's natural environment, the results contained in the first reports of KFS and MoE were compared. It was found that KFS contains a wider variety of survey items, though many of the items are overlapped between the reports of KFS and MoE. It was noticeable that the survey results of KFS and MoE were not always matched even for the same or similar items in the identical target areas. The main causes of the different survey results are suggested to be the differences of the details of the survey conditions between KFS and MoE, such as the season of the surveys and the subjectivity of surveyors, and the type of literatures included in the indoor survey. As a result, it is difficult to directly compare the survey results of KFS and MoE, which leads to low usability of the data and low efficiency of the survey processes. Therefore, it is strongly recommended that the sections and methodologies of survey should be clearly set with consideration for the research purposes. The survey data and geographical information should be digitalized and opened to the public for better accessibility to BDMS information. Also, the survey reports should include English summary, thereby the results can be utilized globally for scientific, cultural and political purposes, such as designation of a heritage site.

This study analyzed the factors having an influence on married woman's childbirth abandonment based on the 2011 materials (the 4th year) of PSKC (Panel Study on Korean Children), KICCE (Korea Institute of Child Care and Education). The analysis showed a few results. First, 'educational expenses for children' and 'physical hardship' were the factors having a major influence on the abandonment of another childbirth. Second, there was some difference in the reason for the abandonment of another childbirth according to the current number of children. That is, women with one child gave up another childbirth because of 'hardship to juggle child-care and work', while women with two children showed 'child-care costs' as a more important reason for the abandonment of childbirth. Third, 'age' and 'instrumental value of children' also had an influence on the abandonment of childbirth. Fourth, there was some difference in the factors having an influence on childbirth abandonment according to the current number of children. The research found that the community child-care environment such as 'leisure and cultural facilities' influenced the women with one child, and maternal psychological factor such as 'marital conflicts' influenced the women with two children in their abandonment of another childbirth.

International commercial arbitration has established itself as the primary dispute resolution mechanism for international business transactions. Certainly, there are commonly-accepted standards that have evolved to reflect an internationally-harmonized approach to issues relating to the taking of evidence. This is reflected in International Bar Association("IBA") Rules for Taking of Evidence in International Evidence("IBA Rules"). This IBA Rules were revised in 2010. Designed to assist parties in determining what procedures to use in their particular case, IBA Rules present some of the methods for conducting international arbitration proceedings. Parties and arbitral tribunals may adopt IBA Rules in whole or in part - at the time of drafting the arbitration clause in a contract or once an arbitration commences - or they may use them as guidelines. They supplement applicable national laws and institutional or ad hoc rules. The IBA Rules were an ambitious undertaking, designed to overcome fundamental cultural differences relating to the taking of evidence under different national court systems. While it is difficult to assess how frequently the IBA Rules are actually adopted by parties, it is fair to say that they have had a considerable influence on the practice of taking evidence in international arbitration. This article mainly describes the essential provisions of IBA Rules, as revised in 2010, including but not limited to production of document, witnesses of fact, party-appointed experts, and tribunal-appointed experts. It also provides a comparison of relevant procedural rules of civil law and common law systems to each of the above mentioned provisions. It is important for arbitration practitioners to understand the differences in the taking of evidence under civil law and common law systems, respectively. This article will be helpful for practitioners and academics not only to understand the revised IBA Rules themselves but also to prepare for, and adequately deal with, the frictions that may arise as a result of the differences in approach for taking evidences. Indeed, so prepared, the arbitration practitioner will be able to anticipate the expectations, perceptions and the conduct of the parties, their counsel and the tribunal members.

This study was aimed to compare and investigate the difference of academic self-concept and social self-concept between multicultural children and general children. The data were collected from a total of 285 multicultural children and 223 general children in elementary school, during three months from February 20, 2014 to May 20, 2014. Collected data were analyzed using t-test, Pearson correlation coefficients, and enter multiple regression with the SPSS 23.0 program. Multicultural children showed lower scores in academic and social self-concept, parents attachment, social support, and school life adaptation than general children. And their mental health level was lower than the general children. The study results were that academic self-concept of multicultural children was influenced by learning activity (${\beta}$=.298), social maladaptation (${\beta}$=-.218), communication (${\beta}$=-.196), and confidence (${\beta}$=.167), which explained for 42.4% of academic self-concept. Social self-concept of multicultural children was influenced by support from friend (${\beta}$=.285), peer relation(${\beta}$=.187), social maladaptation (${\beta}$=-.172), and depression (${\beta}$=-.139). which explained for 46.3% of social self-concept. Since the influence factors of academic and social self-concept of general children and multicultural children have a great power of explanation, they can be used for the intervention program enhancing self-concept for school aged children.

The standardization of test procedures and reproducibility of the toxicity data are prerequisite for the toxicity testing with the earthworm culturing in the laboratory. No in-depth study on culturing conditions of earthworms has been conducted in Korea, even of massive cultural practice is common for composting and production of biochemicals. The earthworms, Lumbricus rubellus and Eisenia foetida, were cultured in three kinds of artificial soil substrates(I, II and III) based on the OECD Guideline, which consist of different ratios of components (sand, sphagnum peat and kaolinite), and fed with a mixture of grain powders. During the period of culturing, the body weight and reproduction parameters were measured. L. rubellus showed the best results for increasing body weight and cocoon production in the artificial soil substrate(I) compared with E. foetida. The cocoon production was significantly high in both species cultured in the artificial soil substrate(I) among the three kinds of soil substrates, but the cumulative cocoon production of L. rubellus was 11 cocoon per worm compared with 3.7 cocoons per worm of E.foetida. L. rubellus, therefore, was more prolific than E. foetida in these culture schemes. The cumulative mortality in both species was less than 10%, and the number of juvenile worms per cocoon ranged from 1.5 to 2.3 and thus did not show any relationships with soil substrates or species. From these data, the culture of L. rubellus in the laboratory could be standardized, but for E. foetida, further study would be necessary to establish the optimal growth conditions in the laboratory.
