Generally, material for radiator of automobile is composed of Al-alloy, but part of radiator material is still composed of Cu. Specially, Al-alloy replaces Cu and Cu-alloy as cooling and heating system material for light weight. Therefore, galvanic electronic cell is formed between Al-alloy and Cu for automobile radiator material, and Al-alloy corrosion is accelerated. So, in this study, galvanic corrosion test of Al-alloy coupling with Cu was carried out in distilled water, tap water, polluted environment and non-freezing solution. And thus corrosion potential and galvanic currrent density of Al-alloy coupling with Cu is investigated.

To study allelopathic porential of naturally occurring substances emitted from Pinus koraiensis, the effects of water exrracts and volatile substances of the tree on callus induction and bacterial culture were examined. The induction and growth of callus were inversely proportional to the concentration of the extracts and of the essential oils supplemnted to Murashige and Skoog's media. However, low concentration(5μl/l) of essential oil promoted callus growth. In germiculture of several bavteria, the extracts of Pinus koraiensis markedly showed the inhibitory effects on bacterial growth. It was, therefore, confirmed that the KDICical substances of Pinus koraiensis tree clearly showed that biological toxic activity at high concentrations.

The complement system comprises a set of essential molecules that bridge the innate and adaptive immune responses. Research has focused on how the complement system's destructive mechanism could potentially be harnessed for cancer treatment. However, cancer subverts the complement system to avoid immunosurveillance. In addition, a complement-triggered biological mechanism that contributes to cancer growth has been identified. Thus, drugs should be designed to homeostatically maintain a normal concentration of complement. This review explores three types of complement-related anti-cancer drugs: therapeutic antibodies, complement inhibitory drugs, and anti-complement regulatory drugs.

Results of experiments conducted in university-based design studio suggests that Building information Modeling invites the adoption of a dramatically different design process, traditional design process and BIM-aided design process. Experiment method is used the actual experiment by students. In contrast to traditional design process rooted in successive refinement of abstractions and dependence on tacit knowledge, the studio BIM-aided design process depends on a complete and comprehensive date base and alterative solutions by complete analysis for helping choice of finial result. BIM viewed as provocateur of design education provides great potential for the critical analysis of how architectural design is taught. The results reflect new ways of teaching and addressing BIM methods and process in the design studio project.

1821년 독일에서 발명된 하모니카는 유럽, 아시아, 미 대륙으로 확산되면서 각 나라와 지역의 기호 및 전통에 따라 수용, 변화되었으며 현재는 약 150여종의 서로 다른 모습으로 그 장점을 따라 활용되고 있다. 하모니카는 인간의 생활에 여러가지 유익을 주는데 다만 심폐기능을 중심으로 하는 신체적 건강뿐만 아니라 정신적, 정서적 건강에 유익한 영향을 미친다. 특히 이러한 하모니카를 활용한 여가생활과 인간관계의 형성은 학령기 어린이와 청소년들에게 더 없이 유익하다. 학령기 어린이와 청소년들의 건강증진과 삶의 질에 미치는 유익한 영향은 구체적으로 학교 자퇴율의 감소, 학습능력의 향상, 수업집중도의 향상, 정신건강수준 향상, 사회관계 형성, 음주, 흡연, 폭력 등 건강위험행위 예방, 신체적, 정서적 안정 등을 들 수 있다. 따라서 하모니카 불기와 감상하기를 학교 재량수업시간에 도입하는 것은 위와 같은 다양한 유익을 확대하는데 의미있는 방법이므로 신중하게 검토할 필요가 있다.

Proteases are important molecules that are involved in many key physiological processes. Protease signaling pathways are strictly controlled, and disorders in protease activity can result in pathological changes such as cardiovascular and inflammatory diseases, cancer and neurological disorders. Many proteases have been associated with increasing tumor metastasis in various human cancers, suggesting important functional roles in the metastatic process because of their ability to degrade the extracellular matrix barrier. Proteases are also capable of cleaving non-extracellular matrix molecules. Inhibitors of proteases to some extent can reduce invasion and metastasis of cancer cells, and slow down cancer progression. In this review, we focus on the role of a few proteases and their inhibitors in tumors as a basis for cancer prognostication and therapy.

This study is concentrated on the concept of health promotion through the consideration and the review of articles and books concerning the theory and practice of health promotion. The study results are as follows: Firstly, the early definitions of health promotion are behavior-oriented concepts in general. Secondly, the concepts of health promotion generally regard environmental factors as of great importance. Thirdly, the concepts of health promotion attach great importance to the aspect of policy. Fourthly, health promotion programs usually need the support from the study results of social epidemiology. Fifthly, some distinguished academic fields have been fused into an integrated field under the concept of health promotion. Sixthly, the two key concepts of health promotion are behavior and environment. This study concludes that health promotion can be defined as "the optimal combination of educational, medical and policy resources to maximize the health potential of people most efficiently or effectively through the change of their behavioral and environmental factors at the level of individual, organization or society.

The advertisement call of anurans functions to attract potential mates. The dominant frequency of an advertisement call is generally getting lower with increased snout-vent length (SVL) of the caller Rana rugosa has an advertisement call tilth a particularly high frequency modulation. We conducted a playback experiment to verify the function of frequency modulation, and investigated the territorial behavior of the frog. The frog has five types of territory defense strategy. Strategy choice depended on the caller's SVL. Small males became satellites or lowered the dominant frequency of their advertisement call, whereas large males actively defended their territory with encounter calls. In response to high frequency (1107 Hz) playback, the frogs lowered their advertisement call frequency, and towered them further in response to the low frequency (1028 Hz) playback. In addition, the number of pulses in a call was increased in response to the playback. These results indicate that the frog avoids physical conflict with competitors by selecting a territory defense strategy suitable for the caller's size, and by lowering its call frequency to disguise its SVL.

Purpose: The purpose of this study was to investigate the factors affecting energy drinks consumption among adolescents in South Korea. Methods: The study is a secondary analysis. Using statistics from the 11th (2015) Korea Youth Risk Behavior Web-based Survey, any variations among the subjects were presented as percentages and analyzed by $x^2$ test and logistic regression analysis. The study sample comprised 68,043 middle and high school students in South Korea. Results: In Model 1 including general characteristics, the significant factors of energy drinks consumption were gender, weekly allowance, cohabitation with family. and economic status. In the final model where health-related characteristics were added, the significant factors were gender, school type, weekly allowance, cohabitation with family, stress level, sadness, drinking, smoking and walking days. Conclusion: The result suggests that intensified education on energy drinks consumption is needed not only at schools, but in the whole community. Also, adolescents' awareness of potential health effects of energy drinks, in particular when mixed in alcoholic beverages, should be increased through health education.
