Quasiclassical trajectory (QCT) calculations of Ne + ${H_2}^+$ reaction have been carried out on the adiabatic potential energy surface of the ground state $1^2$ A'. The reaction probability of the title reaction for J = 0 has been calculated, and the QCT result is consistent with the previous quantum mechanical wave packet result. Quasiclassical trajectory calculations of the four polarization-dependent differential cross sections have been carried out in the center of mass (CM) frame. The P(${\theta}_r$), P(${\phi}_r$) and P(${\theta}_r$, ${\phi}_r$) distributions, the k-k'-j' correlation and the angular distribution of product rotational vectors are presented in the form of polar plots. Due to the well in $1^2$ A' PES, the reagent vibrational excitation has greater influence on the polarization of the product rotational angular momentum vectors j' than the collision energy.

한 미 FTA 발효를 앞두고 미국 통상법에 대한 관심이 더욱 높아지고 있다. 특히, 미국의 반덤핑조치 남용은 이미 여러 선진국들을 통하여 문제가 제기 되어 왔기 때문에 이에 대한 연구가 필요하다. 반덤핑조사를 개시하기 위하여 먼저 "조사대상상품"의 범위를 결정하여야 하지만, WTO 반덤핑협정을 비롯하여 미국 반덤핑법에서도 아무런 규정을 하고 있지 않다. 미국 반덤핑법은 국내 동종상품을 (관세법에 의거하여) 조사 중인 상품과 같거나, 같은 상품이 없는 경우 성질과 용도 면에서 가장 유사한 상품이라고 정의하고 있다. 이처럼 동종상품 분석은 조사대상상품에서 비롯된다. 상무부는 통상의 의미로 조사대상상품을 해석하여야 한다. 유의할 것은 상무부가 일반적으로 조사신청자의 의도를 반영하는 방법으로 반덤핑조사의 범위를 정의할 수 있는 광범위한 재량을 향유하고 있다는 것이다. 그러므로 본 연구는 미국 반덤핑법의 조사대상상품의 범위와 관련한 규정들을 살펴보고, 관련 사례들을 분석하였다. 더욱이, 조사대상상품의 범위는 이후 반덤핑관세명령의 범위에도 영향을 미치기 때문에 이에 대하여도 검토하였다.

The purpose of this study is to develop ICT utilization learning materials for a chapter titled 'Environment Friendly Clothing and Reform of Clothing' in technology and home economics textbooks for Year 2 students in middle school. The research methods were selected from ten types of junior high school technology textbooks, which were revised in 2009, and mainly focused on items such as jeans, shirts, shirts, cardigans, and skirts, Using selected textiles and basic design t-shirts, five works were made using structural and decorative details. The results of this study are as follows. First, textile products shown in the chapter 'Environment Friendly Clothing and Reform of Clothing' are most commonly worn and found in daily life. With regard to a reuse method, structural changes to clothing are proposed. For example, cases relating to the changing of a neckline or the use of a shirt or a sleeve are presented. There are some decoration methods adapted in reuse; using ornaments, such as spangles and emblems, patchwork, shirring and the constucting of collages. Second, following the plan, 5 items are designed with T-shirts, shirts, cardigans and skirts. For the T-shirt design, other fabrics including organza and neoplan are used from design point of view, in addition to reused textile products. Detailed structural changes of necklines, sleeves and collars and detailed and the ornamentation method including shirring, smoking, patchwork and collages are used. Third, this study proposes 6 categories (profile, design planning, diagram, reused textile product, production method and order and pictures of T-shirts developed) under the title of 'T-shirt Made Out of Disposed Clothing', selecting a blog as active teaching and learning material as a part of the ICT utilization in educational settings.

Quasi-classical trajectory (QCT) calculations of H+HLi reaction have been carried out on a new potential energy surface of the ground state reported by Prudente et al. [Chem. Phys. Lett. 2009, 474, 18]. The four polarization-dependent differential cross sections have been carried out in the center of mass (CM) frame at various collision energies. The reaction probability for the depletion channel has been studied over a wide collision energy range. It has been found that the collision energy decreases remarkably reaction probability, which shows the expected behavior of the title reaction belonging to an exothermic barrierless reaction. The results are in good agreement with previous RMP results. The P(${\theta}_r$), P(${\phi}_r$) and P(${\theta}_r,\;{\phi}_r$) distributions, the k-k'-j' correlation and the angular distribution of product rotational vectors are presented in the form of polar plots. The average rotational alignment factor <$P_2(j{\prime}{\cdot}k)$> as a function of collision energy is also calculated. The results indicate that the collision energy has a great influence on the polarization of the product rotational angular momentum vector j'.

Phlegm is defined as the static fluid in excess in one or more parts of the body. It is not only a pathologic product but also a pathogen itself. However, as it says Phlegm is another title for the body fluid. phlegm can be physiological. In Hyungsang medicine. since the Hyungsang which an individual shows determines his or her illness. the principle to treat phlegm also varies according to the individual's Hyungsang. Thus, the author reviewed ‘Jisan’s Special Lectures for Clinicians’ and summarized the concepts and diagnostics of phlegm, and treatment and regimens by Hyungsang medicine. The concepts of phlegm : Phlegm is not only a pathologic product of disharmony of Jung(精), Ki(氣), Shin(神) and Hyul(血) but also a driving force to mature and transform these constituents. Phlegm is another designation for the Fluid. Phlegm can act as an alternative substance or buffering agent. If we describe our body as the habitat of worms. phlegm could be the inhabitant. Diagnostics of phlegm : The infraorbital areas have a dark-gray or blackish coloring. A man who is feminine or a woman who is masculine tends to develop phlegm. One of the major signs of phlegm is pain in Chungwan(中脘). The color of the skin does not change. Treatment of phlegm by Hyungsang medicine. For the Jung type(精科) and the Hyul type(血科), phlegm treatment is to supply Jung and Blood or eliminate Damp-phlegm. The man needs tonifying herbs and the woman needs herbs which promote the flow of Ki(氣). Children and the aged are. tegardless of the nature of disease, to be warmed and supplemented. For the heavy man. treatment is to supplement Ki and eliminate Damp; for the slim man. treatment is to supplement Yin(陰) and purge Heat.

This study reviews studies that used skin temperature in order to establish an emotion evaluation protocol based on skin temperature for home appliances. A survey of skin temperature evaluation papers was conducted by the following five stages: (1) keyword search, (2) title screening, (3) abstract screening, (4) full paper screening, and (5) relevance evaluation. Selected papers were reviewed for: purpose, recruitment criteria of participants, the number of participants, apparatus, procedure, measures, analysis methods, and major findings. Thermistor sensors and thermography are used for the measurement of skin temperature. Skin temperature sensors are attached to 4 - 10 locations on the body and their mean of skin temperature is calculated by Ramanatan's 4-point or Hardy & Dubois's 7-point method. Semantic differential (SD) method and thermography measuring facial surface temperature have been used for emotion evaluation. The SD method provides a set of adjective pairs related to a product and evaluates changes in emotion from the use of the product. The range of facial surface analyzed is defined in the thermal image and temperature changes before and after the evaluation are analyzed. The evaluation items of home appliances include form, color, material, aesthetics, satisfaction, novelty, convenience, pleasantness, and excellence. Many existing emotion studies using skin temperature do not apply physiological and psychological methods. This study provides basic data to establish a skin temperature and emotion evaluation protocol by examining literature for skin temperature and evaluation of sensitivity.
