  • This paper analyzes the relationship of international exchange of Medical School of Sin-an (新安醫學) at the time of Myung and Chung Dynasty, which is one of the most famous regional traditional medicine. The internal reason for the active exchange of Medical School of Sin-an (新安醫學) throughout the ocean was that its major theories were mostly based on Confucianism, which was also the major current in Korea and Japan at the time. This leaded to active interchange between Medical School of Sin-an (新安醫學) of China and Japan and Korea. Secondly, the proliferation of Medical School of Sin-an (新安醫學) was achieved with great help from developing printing operations at the time. Also, the active operation of practitioners of Medical School of Sin-an (新安醫學) such as the attempt to advance to foreign countries along with the 徽州商人 offered an opportunity to introduce Medical School of Sin-an (新安醫學). The international traits of Medical School of Sin-an (新安醫學) can be easily proved by numerous quotes of its classics in many significant classics of Korea and Japan. The influence of Medical School of Sin-an (新安醫學) to Korea started from the Chosun Dynasty; the Treasured Mirror of Eastern Medicine "東醫寶鑑" of Huh Jun and "麻科會通" of 丁若鏞 are the few examples of classics of Korea with quotes of Medical School of Sin-an (新安醫學). The influence of Medical School of Sin-an (新安醫學) on Japanese medicine can be found much before, since Nanbeichao Dynasty. However, the time when many books were imported was during Myung and Chung Dynasty. Also, some of the classics of Medical School of Sin-an (新安醫學) mentioned in "醫籍考" remain only in Japan and not in China; this shows the active exchange between the two countries.

  • Internally Korean insurance market is that whole life products' growth are becoming slowdown that's why new insurance products have appeared on the market in consideration of consumer's needs recently. Externally domestic insurance market competitions has drifted from insurance industry to whole financial industry since bankasurance started. Life insurance companies should open up a new market to survive from severe competitions. Worksite marketing can be an alternative. An insurer make arrangements with an employer about an insurance terms which an insurer offers in Worksite marketing. Then eligible individuals enroll in the plans at their own discretion and pay 100 percent of the premium for coverage through payroll deductions. An employer doesn't need to pay extra money for additional benefit but can raise employee's loyalty and satisfaction of company through worksite marketing. An employee can be covered at discounted premium rate and less strict underwriting guidelines to an insurer compared to individual insurance. In developed countries specially U.S insurance market, Worksite marketing is getting very popular and growing rapidly due to the advantages. Worksite marketing has both individual insurance characters and group insurance characters. Individual insurance characters are that employees enroll in the plans at their own discretion and pay 100 percent of the premium for coverage. Group insurance characters are that actively at work and participation etc. An insurer have to reflect these two characters on Worksite marketing when an insurance company work out a plan for developing products and underwriting guidelines. When an insurer devise worksite products, one should consider participation level which means percentage of eligible employees participating. Participation is related to anti-selection. As we know underwriting is essential for every kind of insurance, especially underwriting plays major role in worksite marketing. We can see that in the below. Firstly, it has a function in calculation of premium rate. When calculate premium rate for worksite products underwriters have to estimate expected participation level and risk factors. So underwriters and acturies keep in close contact with each other. Secondly, underwriting methods are important. When an insurer underwrite worksite products, there are three kinds of underwriting methods. These are Simplified issue underwriting, Full underwriting and Guaranteed issue underwriting. Simplified issue underwriting typically requires no medical examination, but usually requires supplying satisfactory answers to one or several health and/or lifestyle questions. Full underwriting requires a complete medical history questionnaire that may further require an exam. Guaranteed issue underwriting means that coverage is issued without the employee having to provide evidence of insurability. When insurer set the GI limit are usually based on the type of industry, number of eligible employees, the average amount of coverage and participation level. In addition to insurer should have a clear definition of eligible employee on the insurance provision and application form. It will minimize possibility of trouble claims and anti-selection. An insurer also establish preexisting condition exclusion and special guidelines for late entrants. When an insurer introduce Worksite marketing to Korean insurance market, an insurer has to examine market research to analyze potential market and strategy of sales most of all. Also an insurer should review real situation of the U.S, England and Japanese market etc. There are a lot of new technologies about worksite marketing process that an insurer should learn. When an insurer consider many things which we explained it can be a real alternative.

  • The compositions of the phenocrystic feldspars of the Sanbangsan trachyte range from labradorite(An53.6) to andesine(An35.4), and of the microphenocrysts and laths range from andesine(An31.2) to oligoclase(An18.7). Mantled feldspar which forms a thin rim around the phenocrysts and microphenocrysts, is anorthoclase(Or20.5An9.4) to sanidine(Or49.2An1.4). Phenocrystic plagioclase, which shows a distinct zonal structure, represents an oscillatory zoning in which the An content of the zone repeatedly increases or decreases between andesine (An39.3) and labradorite (An51.3) from the core toward the rim, and the rim of the phenocrysts is surrounded by alkali feldspar(Or31.9-39.4Ab63.2-57.0An4.9-3.7), showing the antirapakivi texture. Microphenocryst which does not represent the antirapakivi texture, shows the normal zoning with a decreasing An content (An36.4→An25.6) as it moves outward from the center of a crystal. As a result of X-ray mapping of K, Ca, and Na elements for the feldspar phenocrysts representing the typical zonal structure, shows the oscillatory zoning that six zones show the distinctive compositional differences, and the rims are mantled by alkali feldspar to indicate the antirapakivi texture. The groundmass is composed of K-enriched, Ca-poor alkali feldspar. The antirapakivi texture of feldspar which appears in Sanbangsan trachyte, may have been formed in mixing systems as a result of the juxtaposition of near liquidus melt, rich in alkali feldspar components(trachytic magma), with plagioclase phenocrysts and microphenocrysts already crystallized in a more mafic system.

  • Amidoximated composite fiber adsorbents were prepared for separation of uranium from seawater and characterized by various instrumental techniques, such as IR spectroscopy, CHN elemetal analyzer and SEM. The swelling ratios and yields of the AN-TEGMA and AN-TEGMA-DVB copolymers were decreased with an increase in crosslinklng agents, such as DVB and TEGMA composition. The yield of 85-92% and 82-88% of AN-TEGMA and AN-TEGMA-DVB copolymers respectively were found. The porosity was also decreased with increase in crosslinking compositions, and it was found that the AN-TEGMA-DVB porosity copolymers were smaller than the value of AN-TEGMA copolymer. We investigated that the adsorbent with the composite fiber adsorbents were well dispersed on the surface of Its by SEM. The optimum contents of containing adsorbent in the copolymer was 40 weight percent. The capacity of uraniyl ion through the composite fiber adsorbent containing the amidoxime group was miximized a pH level of 8. Also, if was found that the synthesized composite fiber adsorbent was good material, due to a pH level of 8.3 of seawater, for separation of uraniyl ion from seawater.

  • Objective : The skill of locating acupoints accurately is an essential part of acupuncture treatment. Bone-scale has been used as a basic coordinates to locate acupoints and has been considered as an important factor of locating acupoints. This study was designed to stress the impotance of QieXunMenAn, which means pressing and rubbing softly the surface around the part pointed with proportional method, in locating acupoints. Methods and results : All expressions related with QieXunMenAn, among the descriptions of acupoint locations in ${\ulcorner}Zhenjiudacheng{\lrcorner}$, were investigated. The activity of QieXunMenAn has been regarded as an important method of locating acupoints since Neijing. QieXunMenAn means pressing and rubbing softly the surface around the part pointed with proportional method. It is a process of locating acupoint in detail by finger-sensation after locating the point with proportional method. Xianzhang, Dongmaiyingshou, and Wanwanzhong have been used to describe how to locate acupuncture-point through QieXunMenAn procedure. Xianzhong means a small depression or a pit on the surface of the body. Wanwanzhong describes that it feels very soft and tender. Descriptions related with QieXunMenAn procedures were found in around 87% of acupoint locations, thus stressing out its procedure. Conclusions : Bone-scale and QieXunMenAn do not mean different methods but the procedures that should be both performed every time when we locate most of the acupoints. Until recently, QieXunMenAn has been paid less attention that it should be. OieXunMenAn as well as bone-scale may be necessary to help locate acupoints accurately.

  • Construction of tunnels in a deep crystalline host rock for a potential High-Level Radioactive Waste(HLW) repository inevitably generates an excavation disturbed zone (EDZ). There have been a series of debates on whether a permeability in an EDZ increases or not and what would be the maximum depth of an EDZ. Recent studies show mixed opinions on permeability. However, there has been an international consensus on the thickness of an EDZ; 30 cm for TBM and 1 meter for controlled blast. One of the impacts of an EDZ is on determining the distance between adjacent deposition holes. The void gap by the excavation hinders relaxation of temperature profiles so that the current Korean reference designing distance between holes should be stretched out more to keep the maximum temperature in a buffer region below 100 degrees Celsius. The other impact of an EDZ is on the long-term post closure radiological safety. To estimate the impact, the reference scenario, the well scenario, is chosen. Released nuclides diffuse through a bentonite buffer region experiencing strong sorption and reach a fracture surrounded by a porous medium. Inside a fractured porous region, radionuclides migrate by advection and dispersion with matrix diffusion into a porous medium. Finally, they reach a well assumed to be a source of potable water for local residents. The annual individual dose is assessed on this well scenario to find out the significance of an EDZ. A profound sensitivity study was performed, but all results show that the impact is negligible. Even though the role of an EDZ turns out to be limited on overall safety assessment, still it is worthwhile to study the chemical role of an EDZ, such as a potential source for natural colloids, potential sealing of an open fracture by fine clay particles generated by the process of an EDZ, and alteration of a sorption mechanism by an EDZ in the future.

  • In this paper, an integrated approach is proposed to generate gouging-free Cartesian tool paths for machining sculptured surfaces from 3D measurement data. The integrated CAD/CAM system consists of two modules : offset surface module an Carteian tool path module. The offset surface module generates an offset surface of an object from its 3D measurement data, using an offsetting method and a surface fitting method. The offsetting is based on the idea that the envelope of an inversed tool generates an offset surface without self-intersection as the center of the inversed tool moves along on the surface of an object. The surface-fitting is the process of constructing a compact representation to model the surface of an object based on a fairly large number of data points. The resulting offset surtace is a composite Bezier surface without self-intersection. When an appropriate tool-approach direction is selected, the tool path module generates the Cartesian tool paths while the deviation of the tool paths from the surface stays within the user-specified tolerance. The tool path module is a two-step process. The first step adaptively subdivides the offset surface into subpatches until the thickness of each subpatch is small enough to satisfy the user-defined tolerance. The second step generates the Cartesian tool paths by calculating the intersection of the slicing planes and the adaptively subdivided subpatches. This tool path generation approach generates the gouging-free Cartesian CL tool paths, and optimizes the cutter movements by minimizing the number of interpolated points.

  • This paper looks at the development of the visual system of robots, and the development of image processing algorism to measure the size of an object and the distance from robot to an object for the visual system. Robots usually get the visual systems with a camera for measuring the size of an object and the distance to an object. The visual systems are accurately impossible the size and distance in case of that the locations of the systems is changed and the objects are not on the ground. Thus, in this paper, we developed robot's visual system to measure the size of an object and the distance to an object using two cameras and two-degree robot mechanism. And, we developed the image processing algorism to measure the size of an object and the distance from robot to an object for the visual system, and finally, carried out the characteristics test of the developed visual system. As a result, it is thought that the developed system could accurately measure the size of an object and the distance to an object.

  • The bandwidth enhancement of an aperture coupled microstrip patch antenna(ACMPA) with a high permittivity feed substrate suitable for the integration with MMIC is investigated using variation of an aperture width. As an aperture width increases, the 10 dB return loss bandwidth increases due to the increase of the mutual resonance region between a patch resonance and an aperture resonance. The bandwidth of an ACMPA with extended aperture width is increased up to 35.3 % from 20.8 % of the ACMPA with an aperture of a typical aspect ratio 10:1. The degradation of the radiation characteristics of an ACMPA due to the increase of an aperture width is very small.
