This Thesis analyzes the two forms of Confucian Golden Rule(Shu恕) that were proposed by Zhu Xi朱熹 and Dai Zhen戴震 each other, and researches their ethical significances. Zhu Xi don't regards Shu as universal ethics by itself, while Dai Zhen identify Shu as the ground of universal ethics, According to this thesis, Zhu Xi thought that Shu has a danger of immoral misusage in some situation because Shu is so simplistic form of identification. Because this, Zhu Xi, for the purpose of blocking arbitrary misusage of Shu and holding universality of ethics, suggests that moral sincerity(Zhong忠) of subject is necessary to practice of Shu. Dai Zhen, however, criticizes Zhu Xi's Ethical Structure. In Dai Zhen's view, Zhu xi's idea that the subject has to establish his own morality through Zhong before practice Shu cannot make him escape from subjectivity necessarily. In this point, Dai Zhen revive Shu. His Shu concept means the reciprocity of human desires to each other. But Dai Zhen's idea, as Zhu Xi worried, has a danger of immoral misusage in some situation. On this problem, this thesis elucidates that Dai Zhen' desire concept is not individual various desires but is common basic desires of existence, thereby attests that Dai Zhen's Shu is safe from immoral misusage. This thesis claim that even if Zhu Xi's and Dai Zhen's position is so different, the ethical aims of two scholars is same. They both attempted to overcome the evil of subjectivism and to procure universality of ethics, furthermore to accomplish social fairness. Consequently, this thesis claims that two scholars both walked in same way because both wanted to establish the universality of Shu and to pursue realization of social fairness.

In this paper I will undertake three tasks: first, to identify the difference between John Rawls's liberal conception of liberty and Will Kymlicka's; second, to briefly examine the problems with liberal conception of liberty; finally, to propose a certain alternative that will be able to make liberal conception of liberty more meaningful In Kymlicka's view, Rawls seems to fail to make the best defence of freedom of choice because he wants to explain of individual freedom on the basis of Kant's moral theory about liberty. Kymlicka thinks that it is not a desirable way of defending liberal conception of liberty. According to his liberal theory, Rawls's defence of freedom of choice might make us think that we should have our freedom of choice for its own sake because freedom is the most valuable in the world. So Kymlicka wants to provide stronger argument to defend freedom of choice in liberalism. He insists that it is our projects and tasks that are most important things in our lives. Furthermore, he argues that we should conceive our freedom of choice as a precondition for pursuing those projects and practices that are valued for our good lives. Now I want to look at two concepts of liberty in liberalism with Rawls's theory and Kymlicaka's. In this paper, I shall look at criticisms of the liberal account of freedom of choice. These would give us a certain chance for understanding true freedom.

The emotions that Aristotle treats in Rhetoric II 2-11 are broadly divided into two groups: the one is the so-called basic emotions, the other the emotions that are opposed to them. The reason that he draws attention to the opposite emotions is that, for example, angry judges must be placed in an opposite state. The question is whether the calmness treated in Rhetoric II 3 is an emotion. Because it is treated in the Ethics as a virtue and thus as a trait of character. How is calmness distinguished as an emotion from that as a virtue? And in what way is it opposed to anger? In short, what is the calmness, inasmuch as it is an emotion? This is the question which is the task of this work. The thesis asserted in this paper is that calmness is the disposition to do a service for another that results from praise or some other act that enhances a belief in one's worth. To substantiate the thesis, the following questions are discussed. The first question is whether the calmness could also contain proportions of pleasure and pain. The question also arises whether it could be also treated properly according to the standard 'target person-intentional object-mental state'. Finally, there is a comparison between the concept of calmness in the Ethics and Rhetoric, so that the latter concept places itself in the foreground.

"The four types of temperament" (hereinafter "Sa-Sang Constitutional Medicine") is applied to not only medicine, but also various fields like management, politics, education, etc. Despite that "Sa-Sang Constitutional Medicine" is "Mind-Body Medicine" which is fundamentally based on "Controling Mind and Body", though, it was rarely used for psychotherapy in practical. Practical treatment on clinical medicine is limited to only medicine-treatment or acupuncture-therapy. However treatment on illness and pathological phenomenon suggested by "Sa-Sang Constitutional Medicine" keeps individual's nature in control, and it governs environmental facts: age, region, and socio-cultural factors: alcohol, debauchery, riches, authority(酒 色 財 權). Especially, "Moral Cultivation" in "Sa-Sang Constitutional Medicine" emphasizes the importance of properly understanding vice(邪心) and laziness(怠行) concealed in natural temperament of human being, and pursuing "Understanding Each Other(博通)" and "Upright Conduct by Oneself(獨行)". Furthermore, because "Sa-Sang Constitutional Medicine" is developing medical theory based on "Understanding Others(知人)" and "Straighten Oneself(正己)" doing try integral approach, it has great implications for the present generation that forms much of social connection. Similarly, Ken Wilber who is one of representatives of "World Philosophy" and "Integral Psychology" is suggesting "Integral Life Practice" (hereinafter ILP) - applies practical and heuristic "Integral Approach" to individual experiences. ILP is the only practical discipline for development of viable whole-area. ILP says that there are four core modules: body, mind, shadow, spirit(靈), and five auxiliary modules: morals(倫理), gender(性), work(일), emotion(情緖), relationships(關係性). These nine modules could apply mind-body treatment of "Sa-Sang Constitutional Medicine", and thereby more developed mind-body treatment would be found.

The purpose of this paper is to explore the possibility of backwards causation. For study, this paper was divided into four views as follows: The first view was sometimes suggested by the people such as M. Dummett who distinguished observers from behaviors. According to observers' view, backwards causation is impossible, whereas behaviors' view possible. However, in a real or genuine sense, it is incorrect for us to argue for impossibility of backwards causation from the observer aspect. The second view was supported by J. H. Schmidt. He analyzed the possibility of backwards causation in terms of macro and micro level analysis about the causal events. According to micro level analysis, backwards causation is possible, but macro level analysis impossible. Usually the latter makes the former something miraculous. Under the macro level analysis, backwards causation, at first, seems to be miraculous phenomena which belongs to the micro level analysis. The third view had to do with physical equation, and the fourth view physical phenomena, respectively. John Earman argued for the backwards causation by the transformation from Lorentz­-Dirac equation to a second-order integro-differential one in the field of electrodynamic acceleration. His argument was criticized because of his misunderstanding about the relationship between two equations. On the other hand, Phil Dowe defended a version of Reichenbach's own theory about the direction of causation founded on the fork asymmetrical causal relation. However his view was different from Reichenbach's because the former defended the backwards causation model of Bell phenomena in quantum mechanics. On the contrary, Reichenbach put stressed on the priority of cause in the causal process. Subjectivism has recently been defended by H. Price, under the label of perspectivism. According to him, in a certain sense causal asymmetry is not in the world, but is rather a product of our own asymmetric perspective on the world. He also suggested causal net, the symmetry of microphysics, and so on. As mentioned above, there are many kind of suggestions of backwards causation. However none of them replaced objectively the main streams of the direction of causal process. The main stream has been usually defended by pragmatical ground. That is, effects do not precede their causes although causes cannot be without their effects.

Traditional video compression has developed so far based on hybrid compression methods through motion prediction, residual coding, and quantization. With the rapid development of technology through artificial neural networks in recent years, research on image compression and video compression based on artificial neural networks is also progressing rapidly, showing competitiveness compared to the performance of traditional video compression codecs. In this paper, a new method capable of improving the performance of such an artificial neural network-based video compression model is presented. Basically, we take the rate-distortion optimization method using the auto-encoder and entropy model adopted by the existing learned video compression model and shifts some components of the latent information that are difficult for entropy model to estimate when transmitting compressed latent representation to the decoder side from the encoder side, and finally compensates the distortion of lost information. In this way, the existing neural network based video compression framework, MFVC (Motion Free Video Compression) is improved and the BDBR (Bjøntegaard Delta-Rate) calculated based on H.264 is nearly twice the amount of bits (-27%) of MFVC (-14%). The proposed method has the advantage of being widely applicable to neural network based image or video compression technologies, not only to MFVC, but also to models using latent information and entropy model.

Research into optical signal processing using photonic integrated circuits (PICs) has been actively pursued in various fields, including optical communication, optical sensors, and quantum optics. Among the materials used in PIC fabrication, polymers have attracted significant interest due to their unique characteristics. To fabricate polymer-based PICs, establishing an accurate manufacturing process for the cross-sectional structure of an optical waveguide is crucial. For stable device performance and high yield in mass production, a process with high reproducibility and a wide tolerance for variation is necessary. This study proposes an efficient method for fabricating polymer optical-waveguide devices by introducing the atomic layer deposition (ALD) process. Compared to conventional photoresist or metal-film deposition methods, the ALD process enables more precise fabrication of the optical waveguide's core structure. Polyimide optical waveguides with a core size of 1.8 × 1.6 ㎛² are fabricated using the ALD process, and their propagation losses are measured. Additionally, a multimode interference (MMI) optical-waveguide power-splitter device is fabricated and characterized. Throughout the fabrication, no cracking issues are observed in the etching-mask layer, the vertical profiles of the waveguide patterns are excellent, and the propagation loss is below 1.5 dB/cm. These results confirm that the ALD process is a suitable method for the mass production of high-quality polymer photonic devices.

Since the outbreak of the brown planthopper (Nilaparvata lugens) in 1915 caused tremendous losses in rice production, one of the more effective method of prevention of such a disaster could be the establishment of longterm forecasting system, In 1916 the author indicated there was a correlation between sunspot activities and brown planthopper and the white back planthopper outbreaks. However, the examples seem to be too small size to state a definite correlation. The purpose of the present study IS to revi~w the history of the brown planthopper outbreaks, and to establish a more effective forcasting system. The present forcasting methods are based on light trap catches of adults which already migrate into this country from mainland China. The regular cycle of 11.2 years of sunspot activity began in 1710, and was continued to present. To gather more records of brown planthopper, the author checked 'Joseon Wangjo Silrok' and analized the so-called 'Hwang' 'Hwang-chung' and 'Chung' which have multiple meanings, together with 'Samguk Sagi' 'Goryo Sa' and 'Munheon Bigo.' The results obtained by the about from review of these old literature citations revealed that ten species of insect and unknown species were involved: i. e., pine moth (Dendrolimus spectabilis), army worm (Mythimna separata), brown planthopper (Nilarvata lugens), white-back planthopper (Sogatella furcifera), migratory locust (Locutsa migratoria), rice stem borer (Chilo suppressalis,), mole cricket (Gryllotalpa africana), rice-plant weevil (Echinocnemus squameus), cut worm (Euxoa segetum), and mulberry pyralid Margaronia pyloalis) The suspected incidence of planthopper in old records expressed by 'Hwang' or 'Chung' revealed a total or 25 out of 37 in 'Samguk sagi,' 21 out of 49 in 'Goryo sa,' 9 of 73 in 'Wanjo-silrog,' and none of 8 in 'Munheon bigo' were planthoppers. Therefore, a total of 36 out of 167 records of insect incidence in the old literature can be possibly attributed to planthoppers. The brown planthopper and white-back planthopper migrate together to Korea every year from mainland China, However, the number of each species are differ by year. In 1975 outbreak the brown planthopper was dominant; and the white-back planthopper prevailed in 1946 and 1977 outbreaks, During the course of this study, the author was able to add a new record of outbreak of planthop per. In 1916 the white-back planthopper outbreak caused serious losses in Chungcheong-namdo and Jeonla-namdo, with losses estimated as high as 160 and 190 thousand seok (23.2 and 27.5 thousand M/T), in Naju and Secheon county, respectively. Since 1912, major outbreaks of brown planthopper or white-back planthopper have been recored 5 times. These occurrences coincide and well matched the period of minimum number of sunspots, With these authenticated records of planthoppers, the author believes there is a close correlation between brown planthopper and white-back planthopper outbreaks in Korea and sunspot activities. Therefore, in years of low number of sunspots, we should watch for and expect outbreaks of these. insects. At this time, it will be necessary to provide all possible prevention measures.

Nitrogen dioxide $(NO_2)$ has been regarded as one of the main elements among air pollutants, and we measured $NO_2$ levels of near gas range, kitchen, living room and outdoor on 489 apartments in Pusan area. $NO_2$ were sampled by using Palmes tubes (diffusion tube sampler) during August 16-25, 1995 (summer) and January 15-29, 1996 (winter), respectively. Authors wanted to know comparison of $NO_2$ levels in summer and winter, $NO_2$ levels categorized by variables, and variables affected to $NO_2$ levels. According to this study, we conducted to establish the degree of indoor-outdoor air pollution of urban apartments in Korea and methods to reduce indoor air pollution. The results of this study were summarized as follows: 1) Mean $NO_2$ levels of near gas range, kitchen, living room, and outdoor were $25.9{\pm}10.0ppb,\;23.3{\pm}8.0ppb,\;19.9{\pm}6.1ppb,\;and\;19.0{\pm}6.0ppb$ in summer, and $34.5{\pm}16.8ppb,\;28.2{\pm}13.4ppb,\;25.3{\pm}12.5ppb,\;21.8{\pm}9.8ppb$ in winter, respectively. 2) Mean $NO_2$ levels according to the floor levels were not significantly different in summer, and in winter, $NO_2$ levels were decreased as the floor levels were increasing, but those were increased above 16th floor. 3) Variables showing significant correlation(p<0.05) with $NO_2$ levels were as follows; Summer: floor level, family size, number of family during a meal, number using gas range during rice cooking per day, and natural ventilation. Winter: floor level, family size, number of person who have been respiratory disease in a house, number of family during a meal, total number of meals, and number using gas range during rice or side-dish cooking per day. 4) We suggest that the methods of reducing indoor $NO_2$ levels are ventilation during cooking, complete combustion, decreasing number and time of cooking, and substitution of fuels.
