  • In concrete, the mater over aggregate is ever demanding each year in paralled with rapid development of Construction works from a couple of years ago. Want of most of them which is river gravel among aggregate has made us uneasy to get good gravel in quality. So far, we have counted on gravel, however, the time to turn the use of normal concrete into that of crushed concrete is closing at hand, I think. According to the results of study by Kaplan, Zeitman, Murdock, Hanada, Yamamodo, the shape of aggregate particle have a great effect on workability of concrete, as we know, is well known to the world. Crushed stone, particularly, is inconvenient to handle on account of jagged, angled particle form and rugged surface structure, give rise to inpediments in works, its unit water stands at about $15-20kg/m^3$, and w/c shows the increasing rate of approximately 5-10%, but it is unsuitable to use in terms of regidity. In order to research all of these, I have experimentalized and reviewed the physical character of aggregate and the regidity of concrete, in addition, its relative ratio of the elastic disposition as to gravel and crushed stone.

  • 일반적인 물체와 달리 사람의 얼굴은 표정이라는 중요한 시각적 요소를 포함하고 있다. 이러한 이유로 만화가들은 빛에 의한 음영 이외에도, 장면의 분위기와 캐릭터의 특징을 효과적으로 전달하기 위해 특별한 음영을 얼굴에 그려 넣는다. 이러한 음영은 물리적으로 타당하지는 않지만 얼굴의 형태와 표정을 강조하기 때문에 얼굴 표정의 카툰 렌더링에서 반드시 고려해야 할 사항이다. 이 논문에서는 실제 만화가의 음영 표현방식에 착안하여 캐릭터 얼굴을 위한 새로운 카툰 렌더링 방법을 제안한다. 이를 위해 먼저 다양한 만화 이미지를 수집하여 얼굴의 음영표현을 분석하고, 캐릭터의 표정에 따라 카툰 렌더링을 달리 하기 위해서 음영표현 템플릿을 정의하였다. 그리고 이러한 만화가들의 음영표현방식을 바탕으로 기존의 카툰 렌더링 방법을 발전시켜 효과적으로 캐릭터의 표정을 강조하는 캐릭터 얼굴 카툰 렌더링 시스템을 구현하였다. 마지막으로 사용자평가를 통해 논문에서 제안한 방법의 유용성을 증명한다.

  • Medical technology being developed, the increase of the aged population brings about many changes in financial standard, consciousness and lifestyle. And the increase of a nuclear family and a professional woman makes their family not to be able to support them anymore. Because aged people also don't want to rely on their family, aged people households are growing gradually. These causes make a house and a living environment of aged people to new social problems and these became elements to determine the living quality. In case of advanced nations a house considered of the physical character of aged people has been planned and they can live with various services in their houses and community that they are living without moving: But a hou! se for aged people is initial stage in Korea. And most facilities are poor and just for protection and accommodation. Although concerning a house for the aged according to revised the aged welfare law, companies are waiting to build because of problems of cognition and regulation. Therefore the plan considered of the character of the aged is being needed for the independent and comfortable living of the aged.

  • This study aims to make a comparison between variables influencing female college students' body shame and appearance change intention in individualist culture(Germany) and collectivist culture(Korea, China), that which variable among individual's physical character(BMI), psychological character(public self-image), and sociocultural pressure has the biggest influence in each culture. The findings of the research are as follows. 1. The German group of female college students had the highest BMI, and there were no difference between Korean and Chinese group. Public self-consciousness, sociocultural pressure, ideal appearance attitude, body shame, and appearance change intention were highest in Korea and lowest in Germany. 2. The variables that affected body shame were powerful in the order of sociocultural pressure, appearance internalization, BMI, and appearance awareness in the Korean group of female college students. In the Chinese group, the order was sociocultural pressure, appearance internalization, and public self-consciousness. On the contrary, in the German group the order was appearance internalization, appearance awareness, sociocultural pressure, and public self-consciousness. 3. The variables that affected appearance change intention were powerful in the order of sociocultural pressure, body shame, and appearance awareness in the Korean group of female college students. In the Chinese group, the order was sociocultural pressure, body shame, and appearance awareness, and in the German group, the order was appearance internalization, body shame, and BMI.

  • Supramolecular hydrogels were instantaneously fabricated by mixing aqueous solutions of $\alpha$-cyclodextrins ($\alpha$-CDs) and amphiphilic methoxy (polyethylene glycol) (MPEG)-$\varepsilon$-caprolactone (CL) oligomer, which was synthesized via the ring-opening polymerization of the CL monomer using low-molecular-weight MPEG ($M_n$ of MPEG=2,000 g/mol) as an initiator. The supramolecular structure of the hydrogels was revealed by X-ray diffraction (XRD) analyses. Rheological studies of the hydrogels revealed an elastic character when the number of CL units in the oligomer was more than 2, and the obtained hydrogels showed high storage modulus but relatively low shearing viscosity due to the low-molecular-weight character of the oligomer, which was more preferable for use as an injectable delivery system. The physical properties of the hydrogels could be modulated by controlling the chain morphology and concentration of the oligomers, as well as the feed molar ratio of the oligomer to $\alpha$-CD. The components of the supramolecular hydrogels are biocompatible and can readily be eliminated from the body. These features render the supramolecular hydro gels suitable as drug delivery systems and tissue engineering scaffolds.

  • The originator of the proprioceptive neuromuscular facilitation method was Dr. Herman Kabat, a man who received the bachelor of science degree from New York University in 1932. In 1936 he moved to the University of Minnesota where he served as instructor in physiology and also studies medicine. He received his medical doctorate in 1942. When Dr. Karbat meet Sister Kenny suggested that certain change. She does not receptive his ideas. So that he decided to pursure the treatment of patients. Upon the establishment of the Karbat- kaiser Institute to be opened in 1946. Margaret Knott, the first physical therapist to be employed by him and to become his head physical therapist. In 1948 Vallejo center was opened. Dr. Kabat developed the PNF method combined motions to ascertain the effectiveness of maximal resistance and stretch in facilitating the response of a weak distal muscle. He identified mass movement patterns that were spiral and diagonal in character in 1965. Margaret Knott presented lecture at tile APTA Annual Conference in Las Vegas. The title was In the groove. On December 18, 1978 she passed away at her home in Vallejo. Marie-Louise Mangold is director of the Kaiser Foundation Rehabilitation Center now. She is the Vice President of International Proprioceptive Neuromuscular facilitation Association. About 20 physical therapist working teaching and study at KFRC in Vallejo. PNF neuromuscular mechanism becomes integrated and efficient without awareness of individual muscle action, reflex and a multitude of other neurophysiological reactions. The principles of PNF are visual consideration, verbal consideration, and proprioceptive input consideration with tactile stimulation, joint receptors, appropriate facilitation, stretch reflex normal timing, irradiation, pattern of movement.

  • Comprehensive Research Facility for Fusion Technology (CRAFT) is an integration of different demonstrating or testing facilities, which aim to develop the critical technology or composition system towards the fusion reactor. Due to the importance and challenge of the negative ion based neutral beam injection (NNBI), a NNBI test facility is included in the framework of CRAFT. The initial object of CRAFT NNBI test facility is to obtain a H0 beam power of 2 MW at the energy of 200-400 keV for the pulse duration of 100 s. Inside the negative ion accelerator of NNBI system, the interactions of the negative ions with the background gas and electrodes can generate abundant stray electrons. The stray electrons can be further accelerated and dumped on the electrodes or eject from the accelerator. The stray electrons, including the ejecting electrons, cause the unwanted particle and heat flux onto the electrodes and the inner components of beamline (especially the temperature sensitive cryopump). The suppression of the stray electrons from the CRAFT accelerator is carried out via a series of design and simulation works. The paper focuses the influence of different magnetic field configurations on the stray electrons and the character of the ejecting electrons.
