There have been increasing consumption of luxury fashion and recent marketing researches on luxury syndrome, trading up, etc. in mass fashion today. Historically the consumption of luxury had been concentrated on only upper class in the past. But since 20th century, the mass consumers of modern consumptive society show their interests in luxuries which had been preoccupation of few elite class. Accordingly, it can be thought that the historical review on the changes in the meaning of luxury should be necessary for a better understanding of modern luxury consumption in sociocultural context. The purpose of this study is to grasp the sociocultural meaning of luxury in modern fashion with a holistic viewpoint by examining the changes of luxury consumption in mass fashion. It will be helpful as a conceptual approach of modern luxury consumption. For this, the documentary study has been executed. It focused on since 20th century, which can be the root of mass productive and consumptive society in fashion history. The results are as follows. The luxury in court elite system before 20th century had been concentrated on few elite class exclusively but gradually began to be represented as inferior cheaper version by mass production according to their increasing interests since industrial revolution. The luxuries in elite designer system in the first half of 20th century were represented as illegal design piracy and legal genuine reproduction in spite of problems brought about between originality and copy. The concept of mass as consumer was virtually alienated in both systems. But in fashion system since the second half of 20th century, various types of consumer luxuries has appeared on account of the trading up phenomenon in drastic growth of mass culture.

본 연구는 현재 남한에 입국한 북한이탈주민의 71% 이상을 차지하고 있는 탈북여성의 남한사회 적응과 관련하여 출신성분에 따른 Berry의 문화적응 이론의 재검증을 시도한 연구이다. 이를 위해 북한의 출신성분제도, Berry의 문화적응 이론, 관련 선행 연구들을 검토하였고 IRB심의가 끝난 2014년 12월 15일~2015년 2월 30일까지 FGI 및 설문조사를 통해 탈북여성이 겪는 사회적 정체감과 문화적 유능감을 밝혀보고자 연구를 수행하였다. 연구결과 출신성분에 따른 남 북한정체감(심리적 문화적응 전략), 문화적 유능감, 지각된 동화 압력, 문화이질감의 차이가 없는 것으로 나타났으며 문화적응은 개별적인 사례 특성에 따라 다른 것임을 알 수 있었다. 이러한 연구결과에 기반하여 구체화된 발전과제를 제시하였으며 본 연구의 의의와 함께 후속연구의 과제를 제안하였다.

The class of isotropic almost complex structures, J_𝛿,𝜎, define a class of Riemannian metrics, g_𝛿,𝜎, on the tangent bundle of a Riemannian manifold which are a generalization of the Sasaki metric. This paper characterizes the metrics g_𝛿,0 using the geometry of tangent bundle. As a by-product, some integrability results will be reported for J_𝛿,𝜎.

This paper argues that the hard-boiled detective fiction is not a commercialized imitation of the classical detective novels but a revisionist detective fiction. Producing a radically different type of detectives from the traditional ones, the hard-boiled detective fiction provides a new, opposing paradigm of criminality, class, and masculinity to the classical detective fiction. Classical detective novels, through the heroic portrayal of high-class detectives capturing and punishing lower-class criminals, reassure class hierarchy. Hard-boiled detective novels, however, representing the ruling classes as the root of social oppression and political corruption, define the power elite as criminals. Whereas the classical detective fiction displays aristocratic masculinity, the hard-boiled detective fiction embodies working-class masculinity. The classical detective is generally represented as a genteel dilettante solving the mysteries of crimes, in his leisure time, through logical reasoning and scientific techniques. The hard-boiled detective, however, solves crimes by using violence and earns his living from catching criminals. The hard-boiled detective also maintains an absolute independence by keeping a distance from all forms of authority and connection. The representation of hard-boiled detective as a tough, rebellious, independent guy can be interpreted as a reaction to the advent of corporate capitalism and the rise of labor control in the 1920s.

이 연구는 한국인에서 적용할 수 있는 근력관련 유전적 소인을 ACE 유전자와 ACTN3 유전자를 단일유전자 수준과 다중유전자 수준에서 관계성을 규명하는데 목적이 있다. 연구의 목적을 위해 근력운동종목의 엘리트선수 158명, 국가대표선수 106명, 대조군 676명을 동원하여 ACE ID 다형성과 ACTN3 R577X 다형성 분포를 분석했다. 연구결과, ACE 다형성에서 II 유전형 및 I 대립형질은 유의하게 높은 분포를 가졌고, 반면 DD 유전형 및 I 대립형 질은 유의하게 낮은 분포를 가졌다(Top-Class vs. Control: 41.4% vs. 32.1 for II genotype, 67.1% vs. 57.7% for I allele, p<0.05). ACTN3 다형성에서 RR 유전형 및 R 대립형질은 유의하게 높았고 XX 유전형 및 R 대립형질은 유의하게 낮았다(Top-Class vs. Control: 42.3% vs. 29.0 for RR genotype, 65.3% vs. 54.8% for R allele, p<0.05). 다중유전자 수준에서 근력은 ACE 다형성과 ACTN3 다형성이 조합된 우성조합유전형(II/ID+RR/RX)이 최우수 경기력에서 유의하게 높은 분포를 가졌다(Top-Class vs. Control: 82.9% vs. 66.7% for II/ID+RR/RX, p<0.05). 또한 최우수 경기력을 가진 국가대표는 엘리트와 대조군 보다 유의하게 높은 TGS를 가졌다($66{\pm}0.9$ vs. $58{\pm}1.9$ vs. $56{\pm}2.3$, p<0.05). 이를 근거로 우성조합유전형이 최우수 근력 경기력을 가질 가능성에 대한 승산비는 2.43배(CI:1.45-4.09, p<0.001)였다. 따라서 ACE 다형성과 ACTN3 다형성은 한국인에서 근력과 관계된 유전형으로 확인되었으며, 두 유전자는 상호 조합된 다중유전형에서 근력 경기력에 영향을 줄 것으로 사료된다. 또한 ACE 다형성과 ACTN3 다형성을 조합한 다중유전자는 근력 경기력을 예측할 수 있은 유전적 요인으로 사료되었다.

The purpose of this study was to compare the world class women's hurdlers with kinematic variables Lee Yeon-Kyoung's in the 100m hurdle. Among korea elite female hurdler, Lee Yeon-Kyoung was participated as a subject. Eight JVC video cameras(GR-HD1KR) were used to film the performance of Lee Yeon-Kyoung at a frame rate of 60fields/s. The real-life three-dimensional coordinate data of digitized body landmarks were smoothed using a fourth order Butterworth low pass recursive digital filter with an estimated optimum cutoff frequency of 7.4Hz. After analyzing and comparing Lee Yeon Kyung's kinematic variables with the world top class hurdlers in the woman's 100m hurdle run, the following conclusions were obtained. 1. Lee should be able to increase the speed with over 5.4m/s from start to first hurdle and then maintain the speed range from 8.33m/s to 8.67m/s until 10th hurdle. Lee should have to maintain the speed with 8.51m/s from 10th hurdle to finish line. 2. Lee has to reach her maximum running speed at 5th hurdle and then has to shorten running time with 0.5sec between hurdles. 3. Lee should be able to run around 2.5sec from start to frist hurdle and then maintain under 1.00sec following phases. Lee should be able to maintain under 1.10sec from 10th hurdle to finish line. 4. Lee needs to control a consistent takeoff and landing distance pattern, Lee needs to lower the height of the center of gravity of the body with 0.33m when she clears the hurdles.

21th century is evolving from physical to brain-oriented society, and from class oriented society to network society. In the midst of it, bobos is the new enlightened elite group. In depth analyzationon of the beat generation from the 1950's and hippies from the 1960's, which had influenced the bobos, were done to study on such new and core elite group. According to the research, the emerging of bobos was originated and created from the long gone conflict between the beat and bourgeois, and the hippie and the conservative. And this mixed culture of both free-spirited hippie and materialistic yuppies from the 80's is rapidly growing, and they are easily seem from various commercial advertisements, accessories and fashion designs. In addition, the bobo's were targeted by the main designers, and expressed through bohemian luxury and romantic hippie mood. Naive and childish floral prints, paisley prints that were influenced by the hippies, the hair styles from the 80's and washed denims were seen at the collections. However, the symbolism of the 60's defiant fashion styles seem to fade away but remains only as a style. The comparison and analyzation between the fashion of bobos, hidden meaning of those defiant fashion styles and the aesthetics of it are arranged in the following conclusions.
