  • This study aims primarily to discuss the question 'What does the red fashion boom in Korean society during the 2002 World Cup mean\ulcorner' For this question, it describes fashion phenomena and characteristics that appeared during the time. Specifically, in order to understand the concrete essence of the red fashion boom in terms of clothing and textiles, this study classifies and describes the red fashion boom as 'object, process and symbol' concepts. It investigates each case within the context of fashion. Outside that context, then, the implications of the red fashion boom are examined based on cultural studies and other sociocultural perspectives. This question is considered by focusing on social pressures as ideology, looking at the voluntary behaviour of Korean people in this context and examining several other factors. This is an investigation of the relationship between fashion, society and culture pursuing fashion theory by reviewing the relevant theoretical backgrounds afforded by the humanities and the social sciences. Based upon the above theoretical discussions, it synthesises what factors contributed to the Korean red fashion boom. Finally, this study briefly states their applicability to cultural marketing in its practical aspects. This study has attempted to throw some light on the question 'What does the red fashion boom in Korean society during the 2002 World Cup mean\ulcorner' The Korean Red Fashion Boom emerged from its interrelation with each context of the World Cup, as in the dualism of 'Janus'. That is, the World Cup functioned as the positive face of a festival that collected deep emotions and passion and contributed to the integration of society. Whereas its negative face, ideologically speaking, personified the invisible capitalistic product produced by the nation, enterprises and the mass media. And the implications of the red fashion boom can be interpreted with reference to the two faced World Cup.

  • Grouting is an operation often carried out to consolidate and seal the rock mass in dam sites and tunnels. One of the important parameters in this operation is grouting pressure. In this paper, analytical models used to estimate pressure are investigated. To validate these models, grouting data obtained from Seymareh and Aghbolagh dams were used. Calculations showed that P-3 model from Groundy and P-25 model obtained from the results of grouting in Iran yield the most accurate predictions of the pressure and measurement errors compared to the real values in P-25 model in this dams are 12 and 14.33 Percent and in p-3 model are 12.25 and 16.66 respectively. Also, SPSS software was applied to define the optimum relation for pressure estimation. The results showed a high correlation between the pressure with the depth of the section, the amount of water take, rock quality degree and grout volume, so that the square of the multiple correlation coefficient among the parameters in this dams were 0.932 and 0.864, respectively. This indicates that regression results can be used to predict the amount of pressure. Eventually, the relationship between the parameters was obtained with the correlation coefficient equal to 0.916 based on the data from both dams generally and shows that there is a desirable correlation between the parameters. The outputs of the program led to the multiple linear regression equation of P=0.403 Depth+0.013 RQD+0.011 LU-0.109 V+0.31 that can be used in estimating the pressure.

  • The aim of this study was to analyze the thermal performance through Test-Cell of TI-wall in domestic climate. This study was carried out as follows: 1) The TI-wall was studied for ability to reduce heat loss through the building envelope and analyzed to TIM properties. 2) Test models of TI-wall were designed through the investigation of previous paper and work, measured for winter and spring, and the thermal effects were analyzed. The type of the TIM used in test model is small-celled(diameter 4mm and thickness 50mm) capillary and cement brick(density $1500kg/m^3$) was used by thermal mass. 3) Test-cell of TI-wall was calibrated from measured data and the dynamic simulation program ESP-r 9.0. In these simulations, the measured climate conditions of TaeJon were used as outdoor conditions, and the simulation model of Test-cell was developed. 4) The sensitivity analysis is executed in various aspects with standard weather files and ESP-r 9.0, and then most suitable system of TI-wall are predicted. Finally, The suitable system of TI-wall was analysed according to sizes of air gap, kinds, thickness, and the surface absorption of therm wall. The result is following. In TI-wall, Concrete is better than cement brick, at that time the surface absorption is 95%, and the most efficient thickness is 250mm. As smaller of a air gap, as reducer of convection heat loss, it is efficient for heating energy. However, ensuring of a air gap at least more than 50mm is desirable for natural ventilation in Summer.

  • 현재 옹벽해석에 사용되는 Rankine이나 Coulomb의 토압산정방법은 벽체 뒤의 토사가 파괴상태에 도달하였다는 가정조건에 근거하고 있으며, 이를 위해서는 충분한 횡방향 변위가 발생하여야 한다. 최근의 현장시험 등을 통한 많은 연구에서는 옹벽에 작용하는 수평주동토압이 Rankine이나 Coulomb의 토압보다 크게 나타나고 있음을 보여주고 있으며, 이는 발생 수평변위량과 밀접한 관계가 있는 것으로 판단된다. 본 연구에서는 Drucker Prayer의 지반구성모델을 이용한 유한요소해석을 통하여 캔틸레버식 옹벽의 벽체 지주와 가상배면에 작용하는 수평주동토압을 발생변위와 함께 분석하였으며, 아울러 경사진 뒤채움이 수평주동토압에 미치는 영향도 검토하였다. 그 결과 옹벽에 작용하는 수평주동 토압은 발생변위와 밀접한 관계가 있으며, Rankine과 Coulomb의 방법은 작용수평주동토압을 과소평가하고, 경사진 뒤채움의 수평주동토압증가효과도 과소평가함을 확인하였다. 그리고 본 해석결과를 토대로 수평주동토압을 간편하게 산출할 수 있는 새로운 방법을 제안하였다.

  • Starting in modern times by Le Corbusier, architectures made by concretes are still developing in these times. For several decades, the shape of box architecture has been the most familiar type of buildings. Of course "The concrete is the type of box building" isn't always right, but what we have most seen was the buildings which has been stylized and made by concretes. Through modern times to these days based on international style and functionalism, the type of box building was the most effective and good profit type of architecture which has not disregarded the capitalism. Free-form building are becoming a common place, and many of these are designed and constructed using sophisticated techniques. The main technique being used is Generative Technology of Form for free-form construction. People's interest is growing in this, and it is becoming widely used both abroad and domestically. The purpose of this paper is to investigate the use of Generative Technology of Form which is a digitally adapted design methodology in architecture. The digital design process used for contemporary buildings share many typical features that exist within a standard digital template, but also an increasing amount of mass customization that has to be produced at an additional cost. This paper will summarize these features in terms of free-form architecture, and in terms of the digital design process. In fact, 3D models have to be conceded as main design products considering features of Free Form Design Architecture. However it is practical to design twice over, because all forms of architectural drawings are 2D. From now on, design of Free Form Design Building is not to separate between design process and practical process, but to compound them as unified design system applied the process to communicate information interactively. For this, it should be required to impose unified digital design process and perform researches about effective way to apply in the field of Free-form Design Architecture.

  • The purpose of this study was to investigate weight control and the relative influence of individual variables affecting children's attempts to control weight. The study subjects were 319 elementary school children. First, the average body height and weight of the children who participated in this study was somewhat larger in boys and similar in girls, as compared with the normal body shape of Korean children. More boys were classified as overweight than girls, based on BMI. Both boys and girls were dissatisfied with their body shape, and especially the girls showed higher dissatisfaction rate than the boys did. Almost half of the children were concerned about weight control and girls had higher concern than boys. Of the children, 38.8% had controlled their weight; however there was no difference between their sexes. There were significant differences between children who had and had not experienced weight control in the following variables: stress caused by obesity, body satisfaction, BMI, subjective body shape perception and concern about weight control. Therefore, discriminant function analysis was performed to determine the discrimination of these variables between the two groups. From the analysis results, the most critical factor was BMI in the boys and concern about weight control in the girls. This finding should be reflected in the design of weight control programs for children i.e., boys should be encouraged to perceive correctly their own body shape and to control weight by maintaining a well-balanced diet and moderate exercise over a long period of time, rather than by skipping meals, while girls should be inspired with sound values and attitudes regarding their body shape, rather than provided with the concrete information on how to control weight.

  • This article deals with military thought in general. First I tried to distinguish 'thought' from 'theory', 'philosophy', and 'principle'. Thought means the act of thinking about or considering something, an idea or opinion, or a set of ideas about a particular subject, e.g. military affairs in the present discussion. Theory means a formal statement of the rules on which a subject of study is based or of ideas which are suggested to explain a fact or event or, more generally, an opinion or explanation. Philosophy means the use of reason in understanding such things as the nature of reality and existence, the use and limits of knowledge. Principle means a basic idea or rule that explains or controls how something happens or works. Chapter 3 summarized the characteristics of military thoughts into five points', (i) it is closely related with concrete experiences of a nation; (ii) it includes philosophical and logical arguments; (iii) it relies heavily on the political thought of a nation; (iv) it includes necessarily value-judgments; (v) it contains visions of a nation which are not only descriptions or explanations of military affairs, but also evaluations and advocacies. Chapter 4 considers the relation of international political thoughts to military thought. Throughout the history of the modem states system there have been three competing traditions of thought: the Hobbesian or realist tradition, which views international politics as a state of war; the Kantian or universalist tradition, which sees at work in international politics a potential community of mankind; and the Grotian or internationalist tradition, which views international politics as taking place within an international society. Chapter 5 considers the law of war, which is a body of law concerning acceptable justifications to engage in war (jus ad bellum) and the limits to acceptable wartime conduct (jus in bello). Among other issues, modem laws of war address declarations of war, acceptance of surrender and the treatment of prisoners of war, military necessity along with distinction and proportionality, and the prohibition of certain weapons that may cause unnecessary suffering.

  • A physician has to do his best for the better treatment of his patiensts. But, if a physician cannot remedy his patients because of the lack of hospital facilities, the lack of medical knowledge and etc., the physician must transfer his patients to another suitable hospital immediately. This is called the duty of interhospital transfer of patients. The necessity of interhospital transfer of patients is primarily ocurred in emergency medical care situations. The Supreme Court Decision 2010DO7070 delivered on April 29, 2010 is one of the important decisions related to the duty of interhospital transfer of patients. The Supreme Court ruled that there were the physician's medical malpractice and the causation between the physician's medical malpractice and the death of patient, as the physician has left the patient without due observations for 1 hour and 30 minutes after the caesarean operation inspite of mass bleeding during the operation, and has transferred the patient to another suitable hospital later. And the Supreme Court ruled that the transferring physician has to explain the situation of the patient in detail to the physician being transferred. I agree with the Supreme Court Decision. As decided by the Supreme Court, physicians will treat their patients more carefully and in case of necessity for transfer, physicians will transfer their patients with more caustion. However, the study for this issue should be continued hereafter because concrete standards are not given to lawers and physicians just by the Supreme Court Decisions itself.

  • 지난 십수 년 동안 텔레비전을 시청할 수 있는 플랫폼이 다양해지고 다양한 미디어 형식을 결합시킨 소비가 손쉽게 일어나며 국내 지상파 방송 프로그램 이외의 프로그램 자원이 풍부해지는 포스트 TV 시대가 전개된다. 이 연구는 미디어 환경 변화에 따라 텔레비전 시청 경험의 성격과 의미가 어떻게 달라지고 있는지를 주목해보고자 한다. 특히 월터 옹(Walter Ong)의 관계주의적 시각에서 현재의 텔레비전 시청 환경, 시공간 경험, 사회적 장소로서의 텔레비전, 텔레비전 시청의 의미와 위상 등을 구체적으로 관찰해보고자 한다. 이를 위해 29명의 20대에 대한 심층 인터뷰 조사를 진행하였고, 이러한 인터뷰 사례를 기초로 일상 속에 이용하는 커뮤니케이션 체계가 변화하면서 텔레비전의 의미와 적절성이 어떻게 바뀌고 있는지를 구체적으로 기술하고 이해해보고자 하였다. 이들의 사례는 텔레비전 시청 경로가 다변화되고 소셜 미디어 이용과 연결되면서 텔레비전 시청 개념이 확장되고 있음을 시사한다. 물리적, 상징적 '모이는' 장소로서의 텔레비전의 의미가 여전히 '잔존'하지만, '집단적인 개인화'와 '개인적 집단화' 라는 다양한 층위의 시청 경험이 만들어지고 있음을 보여주고 있다.
