Fluid inclusions in amethyst from the Samcheonpo amethyst deposit of the Waryongsan area, Kyongnam generally grouped into four different types: Type I (liquid-rich and $10{\sim}23wt%$ NaCl, $Th=289{\sim}359^{\circ}C$), Type II (vapor-rich and $2{\sim}10wt%$ NaCl, $Th=304{\sim}365^{\circ}C;$), Type III (halite-bearing, $31{\sim}54wt%$ NaCl, $Th=259{\sim}510^{\circ}C;$), and Type IV ($CO_{2}-bearing\;9{\sim}13wt%\;NaCl,\;126{\sim}277^{\circ}$). Type I, II, and III inclusions are confined in the lower part of the amethyst and Type IV in the upper, which indicates significant hydrothermal activity during the earliest stage of the amethyst growth or the solidus condition of granitic rocks. The earliest fluid exsolved from the crystallizing granitic magma formed Type IIIa which is spatially associated with silicate melt inclusions. The homogenization behavior of Type IIIa inclusions by dissolution of the halite crystal after the bubble disappearance indicates that Type IIIa inclusions were trapped at some relatively elevated pressure. Exsolution of Type IIIb, I, II forming fluids with gradual decrease in their salinity was followed. The last fluid was $CO_{2}-bearing$ fluid (Type IV), which is assumed to be derived by decarbonization reactions with the surrounding sedimentary rocks. It suggests that the fine-grained granitic rocks containing the Samcheonpo amethyst crystallized at the sub-solvus condition saturated with water and exsolved abundant water.

With its history of two thousand years of studying the human mind, Confucianism may be applied to contemporary emotional science for its unique perspectives and methodologies in understanding the origin of the human mind. By examining the Confucian understanding of human mind according to general Confucian ideas as well as the scholar, LEE Whang's, an idea similar to contemporary 'emotion' in Confucianism was discovered. Importance of the sentiment was not in the resulting goodness originating from one's fundamental nature, but rather its goodness was only achieved when human nature manifested itself without any distortion. This good emotion, namely 'sensibility', presents the essential difference Confucian understanding bears in comparison to the contemporary concept. And the system for grasping the human mind was considered to be the viewpoint of examining the contents and subject of function than a formal system of functioning human mind. It assumes the stance of looking into thehuman mind from the general and synthetic view of contemporary cognitive, emotional, biological and philosophical perspectives. Overall, the researchconcludes that there existed a long history of high-level research into the human mind in Confucianism that may satisfactorily provide partial reference and understanding as well as consequent perspectives and knowledge for discovering the common denominator with the emotional science.

Purpose: The authors compared the results of Ender nailing for the proximal humerus fractures with those of the conservative methods radiographically. Materials and Method: Nine patients(mean age: 69 years.) received Ender nailing, and the other nine patients, conservative treatments(mean age: 73 years). All fractures were 2 part fractures. The Ender nails were inserted either through posterior elbow approach or transepicondylar approach. A simple Velpeau bandage was applied to the conservative treatment group. The average follow-up was 15 months. Results: The initial status of the anatomical reduction, i.e., the values of the medial shift, overlapping and the varus agulation, were little changed at follow-up radiographs in both the Ender nailing group and the conservative treatment group. There was no significant difference for the status of anatomical reduction between the Ender nailing group and the conservative treatment group. The stability of fixation by Ender nails, i.e., the degree of fanning out of the nails was poor in most cases. Not a few problems/complications happened in cases of Ender nailing group; back­ing out of the nail in three cases, penetration of the nails into the humeral heads in 3, fractures or cracking of the humerus around the nail insertion area in 4 and reduction loss in one. Conclusion: We could not get better results with the use of Ender nail. We use no longer Ender nails for the proximal humerus fractures. Further studies are needed for the better option for the proximal humerus fractures.

recently, world is progressing large quantity consumption with continuous Innovation and economic growth and pollution is accelerated at these process. Increase of industry activity and service that is point of corporation activity is discharging environmental pollutants at whole process to manufacture of end product and exhaust process from acquisition of raw material for accompanied product production hereupon. At the same time, being promoting resources consumption by that use much raw material, As a result, is becoming obstacle factors in sustainable development. So, corporation's responsibility for environmental protection is emphasized. Corporation which must prepare in green round or environmental problems should consider environmental effects that is happened over whole life of products that include waste treatment after raw material acquisition and use as well as selling end product simply. A Life Cycle Assessment techniques is normalized and standardized in International Standard Organization for technical committee 207(TC 207) world widely, and effort to apply in corporation's activity because mastering LCA techniques in domestic several corporations is undergone actively. Coming into effect of Kyoto's Protocol and International Organization for Standard 14000 series revision are presenting new survival principle in competition between country or corporation. LCA technique may become very useful means to corporation which wish to attempt environment management in real condition that awareness for environment is important. Also, An LCA to each product is going to cause big effects in corporation's whole image as well as competitive power raising for single product. Therefore, this research wishes to examine some instances for the future competitive product development at the estimation of environmental friendliness using LCA techniques and more theoretical considerations of the LCA techniques that can dominate corporation's fate.

The purpose of this studies was analyzed moisture content, rheology and sensual test of jujube jungkwa by addition of water, sugar, fructose at processing of jujube jungkwa for development the optimization for processing of jujube jungkwa. The changes of moisture contents at process condition of jujube jungkwa were increased by increasing of sugar and water quantity. And moisture contents of jujube jungkwa were increased by high fructose quantity and low sugar quantity, but were decreased by high sugar and fructose quantity. The 'b' values of jujube jungkwa at low sugar quantity were decreased by the increasing of water quantity, but increased at high sugar quantity. The cohesiveness of jujube jungkwa at 0.03 kg of fructose were high by the increasing of sugar quantity, but those at 0.065 kg of fructose were high by the decreasing of sugar quantity. And those at 0.050 kg of fructose were similar without the quantity of sugar. The sweet taste of jujube jungkwa were increased by the increasing of water and fructose quantity. The characteristics of jungkwa at conditions of processing for the best quality of jujube jungkwa were 18-20% of moisture content, 2.0-3.0 of 'b' values, 3.0-3.2 of color scores, and 3.3-3.4 of sweet taste scores. The conditions of processing for the best quality of jujube jungkwa were determined to 0.95-1.04 L of water, 0.052-0.060 kg of fructose at 0.95 kg of sugar.

In this work, novel thin film composite (TFC) forward osmosis (FO) membranes are developed via interfacial polymerization on the polysulfone (PS) substrate, using TEOS as the a sol-gel reagent to form hydrophilic interlayer polymer between PS and polyamide (PA). The PS substrate was cast on a very thin polyester nonwoven to reduce membrane resistance. With the incorporation of TEOS (tetraethoxy silane) polymer in the interface between PS and PA, the formed TFC FO membrane exhibits better hydrophilicity and improved water flux, and therefore superior membrane performance. By changing the polymerization sequence of PA interfacial polymerization and TEOS sol-gel condensation, the surface properties and performance of FO membranes are changed significantly. The permeability of FO membranes were estimated using the bench-scale FO test equipment. The distribution of the polysiloxane on composite membrane and morphology are also studied with FE-SEM and EDAX. The PS_PA_TEOS membrane showed highly enhanced water flux (79.2 LMH) but reverse salt flux (RSF) value (7.10 GMH) also increased. However, the flux of PS_TEOS_PA membrane increased moderately (54.1 LMH) without increasing RSF value (1.60 GMH) compare with PS_PA membrane.

The study aimed at identifying the causes of the high level of health application but the low level of use. In other words, the effects of user's innovation resistance (use barrier, value barrier, risk barrier, traditional barrier, image barrier, etc.) were examined. For this study, 378 valid responses were collected by conducting surveys with college students. Findings indicated the higher the level of image barrier of the user, the higher the degree of innovation resistance for the health application, and the higher the degree of innovation resistance, the lower intention of continuous use and recommendation. In addition, the level of use barriers, value barriers and traditional barriers did not have a significant effect on the degree of innovation resistance, suggesting that users familiar with smartphones have low resistance to health applications. The study deepens the theoretical discussion about the adoption and continuous use of new technologies by explaining the use of health applications in the theory of innovation resistance. The findings of the study provide the practical implications that lowering the image barriers rather than the usage barriers, value barriers and traditional barriers will be effective for the adoption and continuous use of health applications.

In the capitalized Joseon Dynasty under the Japanese colonial rule, most Gisaengs (female entertainers) were waiting for men who would save them from financial distress, but others chose to seize the opportunity imposed by the modern times and capitalization to transform their lives. Socialist Jung Chil-sung was one of those who utilized such opportunity to transform themselves through political awakening. The political awakening of Chung Chil-sung was the result of two factors-the historical occasion of the March $1^{st}$ movement and her personal labor experience as Gisaeng. The March $1^{st}$ movement was not only a colossal political incident externally manifested in nationalism and but also an occasion which educed the microscopic anger of a woman named Chung Chil-sung. In the early capitalist society, women with jobs were forced to play not only vocational tasks but also to subject themselves to emotional roles of being obedient and generous. In other words, those early career women suffered feelings such as anger, shame and humiliation, when they were defenselessly exposed to gender hierarchy and gender power in the public sphere. As shown in the case of Chung Chil-sung, these emotions led to a certain political awakening. The political awakening through the labor experience and emotional problems was the fact that helped Chung Chil-sung have a concrete and realistic understanding about the issue of women's economic dependence unlike other female socialists. But, although socialism was relatively the most appropriate language to explain Chung Chil-sung's experience, what she experienced contained several elements that cannot be explained by the elite socialist language. Therefore, her life paradoxically proved the need of lower-class women's lives to be divided and registered as a new emotion and to be politically visualized.
