Background: Alcohol and tobacco use are two major behavioral risk factors implicated in increased morbidity and mortality. Since both substances are widely used in Korea, a concerted effort is currently underway to reduce the use of tobacco and alcohol in Korea. Objectives: Efforts directed toward preparing health promotion planners and health educators from local health departments to organize and implement community-wide interventions to reduce the proportion of people smoking and reduce the average level of alcohol consumption in the community. Methods: Comprehensive multi-media health promotion materials were developed based on health behavior theories and strategies. The materials were developed to introduce a user-oriented developmental approach by making messages more persuasive and organizing content in a user-friendly manner. Health educators from all local health departments in the country were trained in the use of the materials, to enable them to develop community interventions to reduce smoking and drinking. Implications for Practitioners: The process followed in developing the health intervention materials is described in detail to assist practitioners who need to develop effective programs to reduce the use of tobacco and alcohol. Sections of the report explain health intervention theories, specific program activities to include in an intervention, development, organization, evaluation, choosing a target audience, choosing goals of an intervention, and methods of making program content vivid and persuasive.

Vaginitis, also known as vaginal infection and vulvovaginitis, is an inflammation of the vagina and possibly vulva. The three main kinds of vaginitis are bacterial vaginosis, vaginal candidiasis, and trichomoniasis. The purpose of this study was to characterize Lactobacillus plantarum MG989 and L. fermentum MG901 isolated from the vaginas of healthy Korean women in terms of their inhibitory activity against the vaginitis associated pathogens such as Gardnerella vaginalis and Candida albicans. Co-culture experiments showed that the two Lactobacillus strains MG989 and MG901 significantly reduced the viability of G. vaginalis and C. albicans. Also, the two strains were resistant to bile acid up to 1% and their autoaggregation rates were as high as 83.33%. Further studies are underway to demonstrate that the two strains can be applied as pharmaceutical agents for recovering healthy vaginal ecosystem.

Carbon and carbon-based materials are used in nuclear reactors and there has recently been growing interest to develop graphite and carbon based materials for high temperature nuclear and fusion reactors. Efforts are underway to develop high density carbon materials as well as amorphous isotropic carbon for the application in thermal reactors. There has been research on coated nuclear fuel for high temperature reactor and research and development on coated fuels are now focused on fuel particles with high endurance during normal lifetime of the reactor. Since graphite as a moderator as well as structural material in high temperature reactors is one of the most favored choices, it is now felt to develop high density isotropic graphite with suitable coating for safe application of carbon based materials even in oxidizing or water vapor environment. Carboncarbon composite materials compared to conventional graphite materials are now being looked into as the promising materials for the fusion reactor due their ability to have high thermal conductivity and high thermal shock resistance. This paper deals with the application of carbon materials on various nuclear reactors related issues and addresses the current need for focused research on novel carbon materials for future new generation nuclear reactors.

Recently, deep learning and machine learning have attracted considerable attention and many supporting frameworks appeared. In artificial intelligence field, a large body of research is underway to apply the relevant knowledge for complex problem-solving, necessitating the application of various learning algorithms and training methods to artificial intelligence systems. In addition, there is a dearth of performance evaluation of decision making agents. The decision making agent that can find optimal solutions by using reinforcement learning methods designed through this research can collect raw pixel data observed from dynamic environments and make decisions by itself based on the data. The decision making agent uses convolutional neural networks to classify situations it confronts, and the data observed from the environment undergoes preprocessing before being used. This research represents how the convolutional neural networks and the decision making agent are configured, analyzes learning performance through a value-based algorithm and a policy-based algorithm : a Deep Q-Networks and a Policy Gradient, sets forth their differences and demonstrates how the convolutional neural networks affect entire learning performance when using pixel data. This research is expected to contribute to the improvement of artificial intelligence systems which can efficiently find optimal solutions by using features extracted from raw pixel data.

Many of the studies of visual attention that are currently underway are seeking ways to make application systems that can be used in practice, and obtained good results using not only simulated images but also real-world images. However, despite that previous studies of selective visual attention are models intended to implement the human vision, few experiments verified the models with actual humans and there is no standardized data nor standardized experimental method for actual images. Therefore, in this paper, we propose a new performance evaluation techniques necessary for evaluation of visual attention systems. We developed an evaluation method for evaluating the performance of the visual attention system through comparison with the results of the human experiments on visual attention. Human experiments on visual attention is an experiments where human beings are instinctively aware of the unconscious when images are given to humans. So it can be useful for evaluating performance of the bottom-up attention system. Also we propose a new selective attention system that guides the user to effectively detect ROI regions by using spatial and temporal features adaptively selected according to the input image. We evaluated the performance of proposed visual attention system through the developed performance evaluation method, and we could confirm that the results of the visual attention system are similar to those of the human visual attention.

This research attempts to evaluate the globalization concept and the development of advance progress of the Korean clothing and textile industry toward globalization. Globalization is driven by technology, which create the homogenization of tastes. In the business sector, globalization drives not only the physical presence in the foreign countries, but the way of looking at world markets and organizing as a basis for construction. The process of globalization of a company simply consists of exportation, establishment of foreign branch offices and overseas operations. Entrance to the overseas market can be divided into two categories, where one is based upon exportation method, and the other is based upon direct foreign investment. To observe the development of globalization of the Korean clothing and textile industry, a analysis of exportation and direct foreign investment by the industry was conducted. The result revealed the following: (i) The exportation and direct foreign investment of Korean clothing and textile industry has been focused in Asia, and the industry is influenced by cultural and geographic consciousness: and (ii) although the clothing and textile industry of Korea is still incomplete when compared to all industry, the study shows that globalization of the textile and garment industry is well underway.

To achieve lightweight design, research & development of various lightweighting technologies such as hydroforming are underway worldwide. In the case of hydroforming, application of ultra high strength steel is essential for weight reduction of the car. However, considering common high-strength carbon steel, it is not suitable to the actual hydroformed parts since the lack of formability. DP steel offers an outstanding combination of strength and formability as a result of their microstructure. DP steel has high strength and good formability but it's difficult to secure stable quality of welding section because of softening of weld section and chemical composition. Therefore, most of companies use LASER welding when making high strength tube. Electric resistance welding is excellent production method for steel tube manufacturing considering the productivity. Optimum electric resistance welding technology is needed to be developed for application of high strength hydroformed parts using DP steel. This study is comprehensive research & development from electric resistance welding to actual formabililty evaluation.
