  • Technical issues of steel industry change along with other industrial progresses. Traditionally, steel protection from corrosion environment was the major issue and galvanic metal coatings were mainly used to extend the lifetime of steel products. Nowadays, requirements for steel have become more diversified. More various surface and material properties are required from different field of applications. Naturally, functional surface coating has become one of the most studied areas in steel industry. For functional surface coating, various process technologies and coating products are investigated. In this article, recent trends of functional coating technologies and products are introduced with brief technical descriptions of representative coating products.

  • A binding protein of radio-labeled sanjoinine-A (fangufoline) in rat brain cytoplasm was investigated, using an equilibrium dialysis technique. The labeled agent was bound to the cytosol fraction with two distinctly different types of sets in calclum ion-dependent manner. The bound protein was identified as calmodulin by dgel filtration of the sanjoinine-A bound cytosol fraction on a Sephadex G-75 column. Calmodulin was bound to sanjoinine-A bound at two sets of binding sites in the calculated as two at high affinity sites $(Kd=1.1\;mu{M)}$ and four at low affinity sites $(Kd=3.1\;\mu{M)}$.

  • Since the introduction of The Product Liability Law, effective since July 2002, more and more companies and end-users have been giving their attention to the safety of products. A number of existing risk analysis techniques are being implemented to manufacturing sites. However, they have certain restrictions such as incurring different techniques that are to be implemented at each stage of the product development. This is due to their domain of the analysis differing from one to another. Moreover, the results of these analyses are not specific enough, and are subject to further revision. This study proceeds to look at various examinations undertaken on the existing risk analysis techniques. Through implementing them on certain products, investigations on the strengths and weaknesses were ascertained. This has allowed improvements on the existing techniques to be achieved as tell as the development of a new risk analysis technique, 'HuBRA(Human Behavior Risk Analysis)'. Finally the new technique was implemented on products to confirm its effectiveness.

  • This study has to do with creative product in mathematics. We analyze Taylor's creative product according to a different developmental level of creativity, Taylor's creative product inventory, Besemer & Treffinger's creative products analysis matrix, O'Quin & Besemer's creative products semantic scale(CPSS) etc. The purpose of this study is to make creative products semantic scale in mathematics. O'Quin & Besemer's CPSS consists of 55 items, bipolar adjective checklist. We confirm that O'Quin & Besemer's CPSS is not fit to use for mathematics creative products. So we develop Creative Product Semantic Scale in Mathematics(MCPSS) which consists of 33 items, bipolar adjective checklist. Our result will provide convenience to mathematics teacher who guides a student make a creative product.

  • Radionuclides were deposited at forest areas in eastern parts of Japan following the Fukushima Daiichi Nuclear Power Plant incident in March 2011. Ectomycorrhizal (EM) fungi have important effects on radiocaesium dynamics in forest ecosystems. We examined the effect of colonization by the EM fungus Astraeus hygrometricus on the uptake of cesium (Cs) and potassium (K) by Pinus densiflora seedlings. Pine seedlings exhibited enhanced growth after the EM formation due to the colonization by A. hygrometricus. Additionally, the shoot Cs concentration increased after the EM formation when Cs was not added to the medium. This suggests that A. hygrometricus might be able to solubilize Cs fixed to soil particles. Moreover, the shoot K concentration increased significantly after the EM formation when Cs was added. However, there were no significant differences in the root K concentration between EM and non-EM seedlings. These results suggest that different mechanisms control the transfer of Cs and K from the root to the shoot of pine seedlings.

  • Various sensory technologies have been used at different stages of product development. In this paper, the examples of sensory studies in teas and cosmetics were shown, and these could help to increase the contribution of sensory sciences to the development of products in the industry. In classical approach, descriptive analysis with trained panel and consumer acceptability test are very important to identify the sensorycharacteristicsthatdriveconsumeracceptability of products. Recently, some quick and easy sensory evaluation methods were introduced such as CATA (check-all-that-apply), sorting, and $Napping^{(R)}$, etc. to gather information about consumers' perception of the sensory characteristics of products. Although there are many sensory methodologies available in the product development phase, the most important thing is that these have to be correctly selected and designed for target consumers, products, and research purposes in order to develop a successful product.

  • The international community's sanctions against North Korea, triggered by North Korea's nuclear tests and by missile development in the country, are considered the strongest sanctions in history, banning exports of North Korea's major items and limiting imports of machinery and oil products. Accordingly, North Korea's trade volume decreased to the level of collapse after the sanctions, meaning that the sanctions against North Korea were considered to be effective. However, according to this paper, which analyzed the price fluctuations of refined petroleum products in North Korea through the methodology of an event study, the market prices of oil products were only temporarily affected by the sanctions and remained stable over the long run despite the restrictions on the volumes of refined petroleum products introduced. This can be explained by evidence that North Korea has introduced refined oil supplies that are not much different from those before the sanctions through its use of illegal transshipments even after the sanctions. With regard to strategic materials such as refined oil, the North Korean authorities are believed to be desperately avoiding sanctions by, for instance, finding loopholes in the sanctions to meet the minimum level of demand.

  • The objective of this paper is to examine the country of origin effect of products made in the Republic of Korea. The study focuses on the questions of the sources of information in evaluating products; the evaluation of specific product dimensions by Malaysian consumers; and consumers' assessment of different product categories. It reports on the findings of a survey conducted in which 244 responses were obtained. The most common product information source was found to be through advertisements in television and radio.. Products made in Korea had been rated highly for its product style. Consumer electronics were generally found to be the popular preference of product category by Malaysian consumers. The managerial implications of our study are discussed and the limitations of the study are also examined.

  • Rotational molding is a plastics processing technique that is ideally suited to producing relatively large, hollow, seamless parts which are partially or totally enclosed. Designers of plastic parts turn to rotational molding to produce small or large parts of unusual shape that cannot be produced as one piece by other processes, e.g., blow molding and thermoforming. In this paper, in order to enhance the quality of rotational molding plastic products, 1) surface features for the plastic products are characterized by using an image analysis system, 2) maximum tensile strength for the plastic products that are made of materials that consist of Samsung-Atofina R90lU, pigments and two different kinds of calcium carbonate (OMYA CaCO$_3$) is measured and compared with each other by using an Instron universal testing machine, 3) thickness for the plastic products is non-destructively measured to investigate the quality of the plastic products by using an A-scan ultrasonic tester.
