This study was to separate wild yeast from the Houttuynia Cordata Thunb(HC) extracts fermented in traditional way and investigate the characteristics of fermentation from the HC extracts. As a result, the longer the cultivation time, the more the contents of alcohol in $15^{\circ}Brix$ sugar solutions increased. When it reached to 90 hours since it cultivated, it ranked HCE 12%, HCD 11.2%, and HCA 10.5% in order. As for HCF, HCG, HCB, and HCC), this study has shown that the contents of alcohol were from 7.5% through 8.5%. As a result of selecting germ strains like HCE and HCD with the highest alcohol-genicity in the sugar solutions as separated yeast from HC and of comparing and reviewing the existing Saccharomyces germ strains and fermentation power in the medium of HC(Juice extraction of HC : Distilled water(1:1), this study has found out that 'pH' decreased from $4.09{\sim}4.12$ before fermentation through $3.57{\sim}3.78$ after fermentation. And, the sugar concentration decreased from $15.00{\sim}15.19^{\circ}Brix$ through $7.75{\sim}9.57^{\circ}Brix$ before fermentation. Also, the acid value increased from $0.138{\sim}0.210%$ before fermentation through $0.282{\sim}0.45%$ after fermentation. In addition, as the contents of alcohol became $3.6{\sim}4.6%$ after fermentation, isolates HCD and HCE from HC had higher value rather than ones of DJ97, YJK, R12, and RCY separated from persimmons, apples, and grapes. The result value of color was minimum $4.75{\pm}1.44$ and maximum $6.85{\pm}1.63$, and HCE marked the highest record among the items of sensory evaluation. The overall acceptability was in normal level like minimum $3.95{\pm}1.17$ and maximum $5.00{\pm}1.41$. It is considered as it could lower sensory evaluation because the acceptability of flavor was not satisfied. After all, the significance(p<0.05) among the germ strains was not recognized in aspects of color, flagrance, flavor, and overall acceptability.
Social networking sites (SNS), such as Facebook, provide abundant social comparison opportunities. Given the widespread use of SNSs, the purpose of the present study was to examine the impact of exposure to social media-based social comparison on user's negative emotions and discontinuous use intention on SNS. We present evidence that under the use of SNS, social comparison activities diverge into three patterns, with explicit self-evaluation desire made against similar target (lateral comparison), self-defense desire made against less fortunate target (downward comparison), and self-enhancement desire made with more fortunate target (upward comparison). Such social comparison processes frequently arise, as people are increasingly using on SNSs, the downward contacts ameliorating self-esteem with positive emotions, but the upward contacts and standard contacts with lateral status enabling a person to compare his or her situation with others and simultaneously increase negative emotions due to its differences with others. In other words, as people increasingly relying on SNSs for a variety of everyday tasks, they risk overexposure to upward or standard social comparison information that may have a cumulative detrimental impact on future intention on SNS use. This study with survey with 209 SNS users found that these negative emotions lead to negative fatigue (attitude) and then discontinuous use intention (behavior) on SNS. Our findings are among the first to explicitly examine discontinuous use intention on SNS using social comparison theory and our results are consistent with those of past research showing that upward social comparisons can be detrimental.
The CdSe thin films were grown on the Si(100) wafers by a hot wall epitaxy method (HWE). The source and substrate temperature are $600^{\circ}C$ and $430^{\circ}C$ respectively. The crystalline structure of epilayers was investigated by double crystal X-ray diffraction(DCXD). Hall effect on the sample was measured by the van der Pauw method and studied on the carrier density and mobility dependence on temperature. From Hall data, the mobility was increased in the temperature range 30K to 150K by impurity scattering and decreased in the temperature range 150k to 293k by the lattice scattering. In order to explore the applicability as a photoconductive cell, we measured the sensitivity(${\gamma}$), the ratio of photocurrent to darkcurrent(pc/dc), maximum allowable power dissipation(MAPD), spectral response and response time. The results indicated that the photoconductive characteristic were the best for the samples annealed in Cu vapor compare with in Cd, Se, air and vacuum vapour. Then we obtained the sensitivity of 0.99, the value of pc/dc of $1.39{\times}10^{7}$, the MAPD of 335mW, and the rise and decay time of 10ms and 9.5ms, respectively.

The purpose of this study is to draw an implication regarding "Han-jeong-rok" as the proposal on modern lifestyle. This study classified the behavioral patterns pursued in "Han-jeong-rok" in addition to the 'psychological method of practice' and the 'practical method of practice' for the realization of such behavioral patterns pursued in conducting the study. The outcome of this study can be summed up as follows. The result of reviewing the mainstream modern lifestyle indicated that in the well-being craze, practical and selfish tendency were prominent and the side effect of distorted culture of consumerism were also evident. Lohas faced the limitations of lifestyle led by marketing. The slow movement can be differentiated in that it takes even immaterial aspects into consideration including the value of life and etc. However it faces the limitation of being led by community. In the healing craze, modern day people thirst for something that can heal them. All of these people have strong tendency of relying on the external factors for their personal health and well being, and it possesses a weak point in that it can easily be linked to commercial viability. Compared to the same, the implication that Heo Gyun can gain from "Han-jeong-rok" can be summed up as follows. First, "Han-jeong-rok" emphasizes the point that the agent of life is one's self. The modern lifestyle is practical and relies on the external factors, where as Heo Gyun emphasizes that it should start with a serious introspection of life itself. Second, it emphasizes the psychological aspects in leading a leisurely life. Starting with elegant scenic beauty to reading and sophisticated hobbies among others, it indicates that internal satisfaction can be gained and that self-contentment free from cares, is possible. Third, it proposes standardized 'psychological method of practice' and the 'practical method of practice' for the leisurely life. Materialistic and psychological balance is also emphasized in 'practical method of practice'. The limitations of this study is that it was not a clear comparison with "Han-jeong-rok" between contemporary lifestyle and it had stayed in a review study for implications. Furthermore, there is a need for additional study regarding the concept related to landscape and cases included in the "Han-jeong-rok".
Although the study of citation patterns is an important theme within the sociology of science, due to the fact that it is intimately related to the production, reproduction, and evaluation of knowledge, only sustained theoretical research outlining the differences of citation patterns between the hard and soft sciences has been conducted, and empirical studies nevertheless remain few and far between. The perspectives of institutionalism and constructivism have to attempted to explain different citation patterns between the hard and soft sciences as a contrast between 'what one says' and 'who one is'. Therefore, against this background this study examines the 'theoretical' controversy empirically by comparing the contrasting citation patterns of physics, as a representative of hard science, and sociology, as a representative of soft science. The results, in brief, are as follows: the citaton patterns in physics, as in sociology, vary according to the author's status within the hierarchical employment structure, i. e. whether s/he is a full-time lecturer or not, but diversity of citation patterns according to Ph. D. diploma area is unique to sociology. These results would suggest that the explanation of constructivism is more relevant in explaining variance according to the author's status in the employment hierarchy, but the approach of institutionalism is more appropriate to understanding variance due to Ph. D. diploma area. Furthermore, this implies the complex diversity of the citation patterns between the hard and soft sciences, pointing us to the more qualified conclusion that rather than having to choose between institutionalism and constructivism according to a mutually exclusive either/or logic, these two approaches can in fact be mutually complementary, and these approaches should also be applied piecemeal to different levels of phenomena. In conclusion, this comparative research enables us to assert the following two claims: firstly that physics, as a 'science in society', produces knowledge dependent on social context, and secondly that it also possesses a characteristic that transcends locality from the view of a sociology of knowledge.
The characteristic thermoluminescence responses of Teflon thermoluminescent dosimeters to radiations have been studied by the variation of radiation qualities as well as the high dose radiations. The change in the sensitivity of TLDs for different radiation qualities were studied through not only the photon energy dependence but also the change of supralinearity on the photon energy dependence, by exposing $^{60}Co$ gamma rays, the effective X-rays of 44keV, 69keV, 108keV, and thermal neutron of 0.04 eV. The results were as the following: The TL response of $T-CaSO_4$: Dy as a function of absorbed dose was linear up to about 5 Gy, and the response beyond 5Gy was supralinear for $^{60}Co$ gamma rays. The supralinearity of T-LiF-7 became noticeably apparent more than that of $T-CaSO_4$:Dy and also the lower the LET of radiation became the higher the supralinear effects were. No supralinearity appeared for the thermal neutron irradiations equivalent to 10Gy of $^{60}Co$ gamma rays. The relative sensitivities (Rs), which depended on the doses of $^{60}Co$ gamma rays to the TLDs of T-LiF-7 and T-$CaSO_4$:Dy could be, respectively, approximated to the following empirical formula fitted by the least square method: $$R_{LiF}=1.021-0.04581\;logD+0.402(logD)^2-0.405(logD)^3,\;\;5{\times}10^3{\geq}D{\geq}1(Gy)$$$$R_{CaSO_4}=0.976-0.3241\;logD+0.262(logD)^2-0.298(logD)^3,\;5{\times}10^3{\geq}D{\geq}1(Gy)$$.
The 10th constitution established in 1987 serves as the theoretical foundation of democracy in South Korea in the 21st century. Respect for human rights, resistance to injustice, and equality consciousness inherent in this constitution do not conflict with the content of Confucian philosophy. This means that the spirit of the constitution of South Korea in the 21st century was formed under the influence of the idea of democracy and Confucian philosophy. However, the 10th constitution attaches importance to the idea of the 'Basic free and democratic order', which was accepted in the Yushin constitution and inherited by the military forces. The Yushin constitution was affected by liberalism that prioritizes freedom over equality rather than supporting the compatibility between freedom and equality. Therefore, policies to expand the interests of the bourgeoisie rather than public welfare or the interests of the public have been implemented frequently. In particular, during the Lee Myeong-bak and Park Geun-hye regimes, many unequal phenomena were mass-produced. Confucian philosophy in the 21st century critically sees this unequal society. Confucian philosophy thinks that a sense of relative deprivation plays a role of alienating humans and emphasizes the importance of equal relationships. In addition, this constitution emphasizes the rule of law. However, the rule of law attaches importance to positive laws when the spirit of the constitution that contains natural law is applied to reality through systems. This rejects autonomous judgments and choices while inducing reliance on heteronomy. These heteronomous laws as such are accompanied by forcibleness. The positive laws as such can degrade humans into passive beings that indiscriminately adapt themselves to frames already set instead of active beings that think freely and creatively. Confucian philosophy regards and criticizes the rule of law as a system that makes humans into a means. Confucian philosophy regards humans as moral beings instead of tools. Confucian philosophy seeks to build a healthy society through morality accomplished through conscious realization of the principles of life. Confucian philosophy regards humans as originally free beings. Therefore, human beings are autonomous beings, not heteronomous beings. According to Confucian philosophy, humans beings that can realize the morality contained in their inner side by themselves to responsibly carry out their own judgments and choices. Therefore, Confucian philosophy, which considers human beings as beings to be trusted instead of beings to be distrusted, attaches importance to the realization of human decency through edification rather than by punishment through the law. This means that human values cannot be kept by the heteronomy termed positive laws but the identity of humans can be maintained by voluntary choices and judgments. As such, the comment of Confucian philosophy on the problems of liberal democracy and positive laws contained in the 10th constitution can be helpful in essentially solving the contradictions of modern South Korean society.

Textile quality management targets the physical properties of fabrics and the subjective discriminations of color and fitting. Color is the most representative quality factor that consumers can use to evaluate quality levels without any instruments. For this reason, quantification using a color discrimination device has been used for statistical quality management in the textile industry. However, small and medium-sized domestic textile manufacturers use only visual inspection for color discrimination. As a result, color discrimination is different based on the inspectors' individual tendencies and work procedures. In this research, we want to develop a textile industry-friendly quality management method, evaluating the possibility of rapid color discrimination using a digital imaging device, which is one of the office-automation instruments. The results show that an imaging process-based color discrimination method is highly correlated with conventional color discrimination instruments ($R^2=0.969$), and is also applicable to field discrimination of the manufacturing process, or for different lots. Moreover, it is possible to recognize quality management factors by analyzing color components, ${\Delta}L$, ${\Delta}a$, ${\Delta}b$. We hope that our rapid discrimination method will be a substitute technique for conventional color discrimination instruments via elaboration and optimization.
