The purpose of this paper is to explain MacIntyre's critique of moral pluralism of modern society and reveal the limits of his critique of liberalism. It is a distinctive feature of the social and cultural order that we inhabit that disagreements over central moral issues are peculiarly unsettleable. Debates concerned with the value of human life such as those over abortion and euthanasia, or about distributive justice and property rights, or about war and peace degenerate into confrontations of assertion and counter-assertion because the protagonists of rival positions invoke incommensurable forms of moral assertion against each other. We usually call this situation 'modern moral pluralism' and concede as the natural outcome of the activities of human reason under free institution. But in After Virtue, MacIntyre vigorously criticizes modern moral pluralism. The main cause he took which brought about this state of affairs was the failure of 'the Enlightenment project'. According to MacIntyre, the Enlightenment project which has dominated philosophy for the past three hundred years promised a conception of rationality independent of historical and social context, and independent of any specific understanding of man's nature or purpose. But not only has that promise in fact been unfulfilled, the project is itself fundamentally flawed and the promise could never be fulfilled. In consequence, modern moral and political thought are in a state of disarray from which they can be rescued only if we revert to an Aristotelian paradigm, with its essential commitment, and construct an account of practical reason premised on that commitment. But one of the deepest difficulties with the argument of After Virtue is that the very extent of its critique of the modern world seems to cast doubt on the possibility of any realistic revival under the conditions of modernity of the Aristotelianism which MacIntyre advocates. Especially when we consider we are not only the characters found in our narratives but also we ourselves are the author of our own narratives. Moral pluralism is not seen as disaster but rather as the natural outcome of the activities of human reason under enduring free institutions.

The purpose of this study was to investigate the effect of either endurance training only or endurance and weight training on muscle morphology and oxidative enzyme activities in human skeletal muscles. Fourteen healthy males were randomly divided into one of two experimental training groups, either swim exercise training (n=7, ST) or combined exercise training (swim and resistance exercise training; n=7, SWT). The change of muscle fiber type was not significantly different between ST and SWT following 6 weeks of exercise training. Mean cross sectional areas as well as the numbers of capillary of different types of muscle fiber were not also significantly different from baseline for both exercise training groups (p>.05) although the tendency of increase were more notable in SWT. All oxidative enzyme activities (i.e., ${\beta}$-hydroxyl acyl dehydrogenase, citrate synthase, and carnitine palmitoyl transferase) were marginally higher in SWT compared to ST even though statistical power did not reach the level of significance. Based on these results, it was concluded that performing of combined (swimming and weight) exercise training could be the better modality for improving muscle morphological changes and oxidative enzyme activities than performing of only single aerobic exercise intervention in young healthy human skeletal muscles.

In this study, the total polyphenol contents, antioxidant activities and anti-proliferation effects of HepG2 cell lines in organic slovent fractions obtained from the main methanolic extract of P. yezoensis were analyzed. The polyphenol content of the $CHCl_3$ fraction was $10.3{\mu}g/mg$, slightly less than $13.08{\mu}g/mg$ of the water fraction, but $ED_{50}$ estimated by measuring DPPH free radical scavenging activity exhibited the highest $16.96{\mu}g/ml$ in the $CHCl_3$ fraction. The proliferation effects of $CHCl_3$ and EtOAc fraction toward HepG2 cells inhibited in a dose-dependent manner, showed 90% inhibition when treated for 24 hr at $900{\mu}g/ml$ of $CHCl_3$ fraction. Meanwhile gene expression patterns in HepG2 cells treated $50{\mu}g/ml$ of $CHCl_3$ fraction were identified with microarray analysis. Concerning the efficacy of P. yezoensis, gene ontology analysis explored the genes associated with response to molecule of bacterial origin, vitamin D metabolic process, and response to nutrient. Thus IL6R, CYP1A1 were selected as significant genes based on expression patterns of HepG2 cells, and pathway analysis indicates that ARNT might be considered as a upstream regulator. Also, expression analysis of IL6R and CYP1A1, activity of upstream regulator ARNT in HepG2 cells was confirmed based on Western blotting analysis at the protein level after being treated with 50 and $100{\mu}g/ml$ of $CHCl_3$ fraction.

As computer graphics, virtual reality and augmented reality technologies have been developed, in many application areas based on those techniques, interaction for 3D space is required such as selection and manipulation of an 3D object. In this paper, we propose a framework for a vision-based 3D interaction which enables to simulate functions of an expensive 3D mouse for a desktop environment. The proposed framework includes a specially manufactured interaction device using three-color LEDs. By recognizing position and color of the LED from video sequences, various events of the mouse and 6 DOF interactions are supported. Since the proposed device is more intuitive and easier than an existing 3D mouse which is expensive and requires skilled manipulation, it can be used without additional learning or training. In this paper, we explain methods for making a pointing device using three-color LEDs which is one of the components of the proposed framework, calculating 3D position and orientation of the pointer and analyzing color of the LED from video sequences. We verify accuracy and usefulness of the proposed device by showing a measurement result of an error of the 3D position and orientation.

The purpose of this study is to present the development direction of future reading education by examining the characteristics of reading materials within the high school textbook developed as the 2015 revised curriculum. For this purpose, reading materials of high school textbooks were analyzed in Korean language, mathematics, English, integrated science, and integrated social studies. The analysis criteria of reading materials were subject type, purpose, and student activities. As a result of the study, reading materials on various themes such as humanity, liberty, culture, environment, and district were presented in the integrated society and integrated science textbook of the 2015 revised curriculum. In particular, the Korean language curriculum was composed of a unit called "reading one book in one semester". However, most reading materials have no guidance on reading effective or reading direction, and lack of reading materials and information for extended reading. The reader's reading of the textbook was found to be simply supplementing the learning content of each unit or presenting fragmentary cues for conceptual purposes. This suggests that there is a lack of awareness of students' interest in reading, internalization of reading, and extension of reading. In this paper, we suggest supplementary materials of reading materials for expanding the high school textbooks, and explore the developmental relationship between textbooks and reading education through suggestions on aspects of textbook composition and teaching methods.

The fundamental objective of cultivating organic farm produces is to preserve the natural environment and protect eco system so as to maintain the environment where people can live. In the current social atmosphere, the value and attitude of the college students to the environment are significant as they will take the leading part in the future. College students in Busan participated in the survey for the study to prove the moderating effect of the confidence with organic farm produces by investigating the casual relationship among the purchase intention, the environmentally-friendly attitude, and the consumption value of college students. The questionnaires were distributed over the period from October $15^{th}$, 2016 to $30^{th}$.261 papers of the questionnaires were analyzed with SPSS (V 23.0) and AMOS (V 21.0) programs. The analysis on Confidence, Confirmatory Factors, Structural Equation Modeling was compared with Chi-square considering the degrees of freedom between the two models in order to investigate the moderating effect from the purchasing frequency. The result from the analysis confirms that there is a casual relationship between college students' values of organic farm products and the environmentally-friendly attitude. Consumer confidence has a moderating effect on the attitude and purchase intention. As it can be seen from the result of the analysis, it is necessary for municipal governments and the government to push ahead with the policies on organic farm products in the future as it is proved that there is a casual relationship among the attitude, purchase intention and the students' values of the organic farm products.

When most middle-aged women live in a time when they have to take responsibility for their lives, they feel lonely when they realize that their experience of not expressing their feelings properly has ended up being left alone due to their own existence and loss. As the first step in conscious awareness of unconsciousness of middle-aged women through analytical psychology, we performed "Mandara" and "Nanhwa Mandara," which meet me inside. The intermediate stage can be divided into transition and work phase. The working phase, develops one's own advantages and unique strengths that meet the inner world of promoting and acting values, correctly looks at reality, corrects emotion perception and balance, and is self-contained, seed mandala, associative mandala. They performed the strong points of mandala, the free mandala, and the Western mandala. The results of the study showed that mandala art therapy was found in middle-aged women. First, Mandarin art therapy experience affects the physical, psychological and human relations aspects of middle-aged women. Second, middle-aged women's experience of individualization through mandala art therapy shows psychological reversals and affects positive thinking and self-effectiveness. This study was suitable for qualitative research that approached the essence through practical understanding and direct exploration of research participants, and it is meaningful to suggest that it is necessary to develop an art therapy program through various mediums considering the lack of art therapy research in middle-aged women and problems experienced by the physician.

The period circadian clock gene 3 (PER3) plays a role in the mammalian circadian clocksystem. A regular exercise regime may affect the PER3 transcription in skeletal muscle. Although the effects of day length on circadian and circannual processes are well established in humans and mice, the influence of exercise on these processes in the horse has not been investigated. The present study investigated the expression of the PER3 gene following exercise in a thoroughbred breed of Korean horse. In addition, a comprehensive in silico nonsynonymous single nucleotide polymorphism (nsSNP) analysis of the horse PER3 gene and predicted effects of nsSNPs on proteins were examined. The expression of PER3 in skeletal muscle was significantly upregulated after exercise. Four nsSNPs were functionally annotated and analyzed by computational prediction. The total free energy and RMSD values of PER3 gene showed causative mutations. The results showed that nsSNP s395916798 (G72R) was associated with residues that have stabilizing effects on structure and function of PER3 gene. This study documented role of PER3 gene in phenotypic adaptation related to exercise in skeletal muscle. Further, the SNPs in PER3 could serve as useful biomarkers of early recovery after exercise in racehorses.

정보검색 시스템을 대하는 대부분의 이용자의 대답은 '이용하기에 어렵다'라는 것이다. 기계적인 정보검색을 기본 철학으로 하는 기존의 matching paradigm은 정보 곡체를 여기 저기 내용을 옮길 수 있는 물건으로 간주한다. 그리고 기존의 정보시스템은 이용자가 시스템을 구성한 사람의 의도 (즉, indexing, cataloguing rule)를 완전히 이해한다면, 즉 완전하게 질문식(query)을 작성한다면, 효과적인 검색을 할 수 있는 그런 시스템이다. 그러나 어느 이용자가 그 복잡한 시스템을 이해하고 정보검색을 할 수 있겠는가? 한마디로 시스템을 설계한 사람의 의도로 이용자가 적응해서 검색을 한다는 것은 아주 힘든 일이다. 그러나 우리가 이용자에 대한 인식을 다시 한다면 보다 나은 시스템을 만들 수 있다고 본다. 우리 인간은 아주 창조적이어서 자기가 처한 상황에서 이치에 맞게끔 자기 나름대로의 행동을 할 수 있다(sense-making approach). 이 사실을 인식한다면, 왜 이용자들의 행동양식에 시스템 설계자가 적응을 못하는 것인가? 하고 의문을 던질 수 있다. 앞으로의 시스템이 이용자들의 자연스러운 행동 패턴에 맞게 끔 설계된다면 기존의 시스템과 함께 쉽게 이용할 수 있는 편리한 시스템이 설계될 수 있을 것이다. 그러므로 도서관 및 정보학 연구에 있어서 기존의 분류. 목록에 대한 연구와 이용자체에 대한연구(예를 들면, 몇 시에 이용자가 많은가? 어떤 종류의 책을 어떤 계충에서 많이 보는가? 도서 및 잡지가 어떻게 양적으로 성장해 왔는가? 등등의 use study)와 함께 여기서 제시한 제3의 요소인 이용자의 인식(cognition)을 시스템설계에 반드시 도입을 해야만 한다고 본다(user-centric approach). 즉 이용자를 중간 중간에서 도울 수 있는 facilitator가 많이 제공되어야 한다. 이용자의 다양한 패턴의 정보요구(information needs)에 부응할 수 있고, 질문식(query)을 잘 만들 수 없는 이용자를 도울 수 있고(ASK hypothesis: Anomolous State of Knowledge), 어떤 질문식 없이도 자유스럽게 Browsing할 수 있는(예를 들면 hypertext) 시스템을 설계하기 위해서는 눈에 보이는 이용자의 행동패턴(external behavior)도 중요하지만 우리 눈에는 보이지 않는 이용자의 심리상태를 이해한다면 훨씬 나은 시스템을 만들 수 있다. 이용자가 '왜?' '어떤 상황에서,' '어떤 목적으로,' '어떻게,' 정보를 검색하는지에 대해서 새로운 관심을 들려서 이용자들이 얼마나 우리 시스템 설계자들의 의도에 미치지 못한다는 사실을 인식 해야한다. 이 분야의 연구를 위해서는 새로운 paradigm이 필수적으로 필요하다고 본다. 단지 'user-study'만으로는 부족하며 새로운 시각으로 이용자를 연구해야 한다. 가령 새롭게 설치된 computer-assisted system에서 이용자들이 어떻게, 그리핀 어떤 분야에서 왜 그렇게 오류 (error)를 범하는지 분석한다면 앞으로의 computer 시스템 선계에 큰 도움을 줄 수 있을 것으로 믿는다. 실제로 많은 방법이 개발되고 있다. 그러면 시스템 설계자가 가졌던 이용자들이 이러 이러한 방식으로 정보검색을 할 것이라는 예측과(즉, conceptual model) 실제 이용자들이 정보검색을 할 때 일어나는 행동패턴 사이에는(즉, mental model) 상당한 차이점이 있다는 것을 알게 될 것이다. 이 차이점을 줄이는 것이 시스템 설계자의 의무라고 생각한다. 결론적으로, Computer에 대한 새로운 지식과 함께 이용자들의 인식을 연구할 수 있는, 철학적이고 방법론적인 연구를 계속하나가면서, 이용자들의 행동패턴을 어떻게 시스템 설계에 적용할 수 있는 지를 연구해야 한다. 중요하게 인식해야할 사실은 구 Paradigm을 완전히 무시하라는 것은 아니고 단지 이용자에 대한 새로운 인식을 추가하자는 것이다. 그것이 진정한 User Study가 될 수 있는 길이라고 생각하며, 컴퓨터와 이용자 사이의 '원활한 의사교환'이 필수불가결 한 지금 우리 학문이 가야 할 한 연구분야이다.

Although 'the International Ship Registration Act' has been enacted in Korea as of 1997, its effect is still in question to make shipowners and operators flag in or reflag because of insufficient incentives for them. Therefore, 'the Special Law for Jeju Free International City' has been established and the system of 'Special Ship Registration Zone' has also been enforced. Despite this, few studies were carried out to measure the relative importance of factors for Jeju International Ship Register yet. Against this backdrop, the purposes of this study are firstly, to investigate a relative importance of Jeju International Ship Registration System using AHP(Analytic Hierarchy Process) and secondly, to compare the characteristics of Flags of Convenience(FOC) with International Ship Register(ISR) which was adopted by several Far East Asia Countries(e.g., China, Hong Kong, Chinese Taipei and Japan). Moreover, this study aims to compare FOC with ISR in terms of shipping policy, ship management, and expenses and tax policy. In this paper, the factors were constructed with four high levels consisting of twenty one low levels to evaluate Jeju International Ship Register by utilizing Expert's brainstorming and AHP. According to the results, it is critical to expand the exemption and tax-related expenses, and also manage foreign-related systems systemically. This study provides important implications to maintain the tonnage tax system for ships effectively as well as to intensify the competitiveness of Jeju International Ship Register System.
