It has been 20 years since the cultural contents were newly emerged in the late 1990s and grown in our society. However, efforts to establish culture contents concept and to establish cultural contents as a separate discipline are relatively poor. There may be various reasons, but the most important thing is that it failed to cover the broad sense of the word 'cultural contents' and to present a key concept through the core. Therefore, this study examined the possibility of securing the conceptual resources necessary to lay the foundation for cultural contents within play, under the premise that cultural contents should be play studies in the 21st century. In order to do this, this paper examined the meaning of play in each of the three conceptual categories, ie, mimesis, aesthetics, and power, which are deemed to be related to the meaning of cultural contents that we currently use. As a result, it has been confirmed that play is used in various ways in connection with various concepts such as emotion, art, percept, cognition, education, coincidence, power, hegemony, class, religion, ritual. These various uses of play concept can give cultural contents researchers an opportunity to study cultural contents from a play perspective.

Various security threats, such as North Korea's nuclear tests and intercontinental ballistic missile developments, are becoming issues. Considering the current security situation in South Korea, proper selection of weapons and efficient defense acquisition systems are essential. In this paper, we conduct a survey and analysis of the defense core technology necessary for the development of weapons systems, and review whether current defense research and development is carried out efficiently. A theoretical study was conducted on ways to enhance the linkage between defense core technology and weapons systems development. As a result of the study, the necessity for development of weapons systems and the linking of defense core technology planning with the need for institutional improvement in enhanced utilization of defense core technology were derived. We propose a method for a long-term weapons systems concept plan that integrates defense core technology planning with forces planning and pre-project research programs to improve planning efficiency.

Drone was originally developed for air force aircraft or missile exercise shooting targets, and is being considered as the entire unmanned aircraft to the public. The core concept of a drone can be divided into 'unmanned' and 'aircraft'. However, there are many questions about whether the Fourth Industrial Revolution, expressed as a convergence scientific innovation, is appropriate at a time when smart cities are proposed as a concept of new urban spatial formation, and the role of self-driving vehicles, including drones, is being emphasized within the new urban integrated transport system. In this study, the concept of the existing drones was analyzed for the development process, definitions in each country's laws, and the results of the preceding research to present a concept suitable for future society and a unified term. It is not desirable to define a drone for the purpose of a country, an institution, or an operating entity, depending on the circumstances of the era. It is more reasonable to find the concept of a drone based on human life than in the traditional way, and more reasonable considering the development of the drones in the future. Subsequent studies should be more detailed, more data and research results analyzed, and discussed areas that were not covered in this study. Based on this, research should also be conducted on a variety of topics, including legislation, preparation of operational regulations, and related industrial processes and regulations.

As androgny presented by feminism still appear in contemporary fashion since mid 1980's feminism as a social phenomenon can be considered to habe influenced fashion history. This paper surveys the sex images of androgynous look that appeared in contemporary fashion into bisexual image and neutral images based on the feminist aspects of changes in contemporary fashion. As stated above bisexual images and neutral images of androgynous look shown in clothing are an attempt to reach one single integrated complete being by overacoming 'femininity' or 'masculinity' and combining the element of the two sexes. Consequently androgynous look creates new attraction by harmoniously coordinating characteristics of the two sexes instead of totally differentiating between masculinity and femininity that are represented in the form of clothing that has conceptual visual characteristics. Following are the conclusions of the reseach of this paper. First 'androgynous' as a feminist sex concept reflects the spirit of the times. Since the sex roles are divided and diversified and the concept of femininity is changing the concept of androgyny requiring both masculine and feminine characteristics in an essential sex concept for sucessful conduct of roles in a complex modern society. Second the integrated human image of androgynous look has led to a new culture with fashion trends that has been ahead of times by curing the functions of fashion to differentiate between men and women. Third androgynous look at the turn-of-the-centuy will not cease to exist but be a lasting fashion phenomenon while the sex concept presented by feminism has become the core to destrov the dichotomous fashion style of the 20th century. Fourth androgynous look is expressed in various manners in contemporary fashion since it shown how human beings accipt the adaptation method desperately required by the contemporary times. Androgynous look can be viewd as the desire for ultimate freedom that can be acquired by destroying the dichotomous sex concept and as the will to become a subject of the world as integrated human being. As we look into fashion culture creation of fashion is not the result of an accidental cause or an individual's work but the reflection of the spirit of the times. In this sense androgynous look introduced by a new sex concept to contemporary fashion has reflected the spirit of the times and led the cultural atmosphere and moreover it is an important fashion style that can characterize the contemporary times while lasting in the future.

Under the government supported long-term nuclear R&D program, the severe accident research program at KAERI is directed to investigate unresolved severe accident issues such as core debris coolability, steam explosions, and hydrogen combustion both experimentally and numerically. Extensive studies have been performed to evaluate the in-vessel retention of core debris through external reactor vessel cooling concept for APR1400 as a severe accident management strategy. Additionally, an improvement of the insulator design outside the vessel was investigated. To address steam explosions, a series of experiments using a prototypic material was performed in the TROI facility. Major parameters such as material composition and void fraction as well as the relevant physics affecting the energetics of steam explosions were investigated. For hydrogen control in Korean nuclear power plants, evaluation of the hydrogen concentration and the possibility of deflagration-to-detonation transition occurrence in the containment using three-dimensional analysis code, GASFLOW, were performed. Finally, the integrated severe accident analysis code, MIDAS, has been developed for domestication based on MELCOR. The data transfer scheme using pointers was restructured with the modules and the derived-type direct variables using FORTRAN90. New models were implemented to extend the capability of MIDAS.

In this article, the fundamental concept, characteristics and application potentials of coreless printed-circuit-board (PCB) transformers are described. Coreless PCB transformers do not have the limitations associated with magnetic cores, such as the frequency limitation, magnetic saturation and core losses. In addition, they eliminate the manual winding process and its associated problems, including labor cost, reliability problems and difficulties in ensuring transformer quality in the manufacturing process. The parameters of the printed windings can be precisely controlled in modern PCB technology. Because of the drastic reduction in the vertical dimension, coreless PCB transformers can achieve high power density and are suitable for applications in which stringent height requirements for the circuits have to be met. A transformer's power density of $24W/cm^2$ has been reported in a power conversion application. When used in an isolation amplifier application, coreless PCB transformers tested so far enable the amplifier to achieve a remarkable linear frequency range of 1MHz, which is almost eight times higher than the frequency range of 120kHz in existing Integrated-Circuit products. PCB materials offer extremely high isolation voltage, typically from 15kV to 40kV, which is higher than many other isolation means such as optocouplers. It is envisaged that coreless PCB transformers can replace traditional core-based transformers in some industrial applications. Their application potentials deserve more attention and exploration.

As XBRL applications for sharing the contents and semantics of business reports get activated, it is increasingly necessary to reuse components systematically by the standardization in the national level. The current standardization of Korean electronic documents follows the "Guideline for XML Documents Development", which aims to maximize the reusability of components by providing a business library as well as the UN/CEFACT core components methodology. XBRL takes the same approach with the standardization of electronic documents in that their components (concepts and their structures) are defined using XSD. In XBRL, however, concept are restricted to specific types and diverse relationship types can be defined for associating the concepts to themselves and other additional information. As a result, there are some issues that may not be solved by just applying the guideline to XBRL. This paper presents a basic method for applying the methodology to XBRL applications in order to realize the systematic reusing and standardization of XBRL documents in the national level. For case analysis, FSS (Financial Supervisory Service) income statement is employed to demonstrate the possibility of the method.

This paper describes an on-going national R&D program for the development of a gas turbine/fuel cell hybrid power generation system and related R&D activities. The final goal of this program is to develop a 200kW-c1ass gas turbine/fuel cell hybrid power generation system and achieve high efficiency over $60\%$ (AC/LHV). In the first phase of the development, a sub-scaled 60kW-class hybrid system based on the 50kW-class microturbine and the 5kW SOFC will be developed for the purpose of concept proof of the hybrid system. Core components such as the microturbine and the SOFC system are being developed and parallel preparation for system integration is being carried out. Before the core components are assembled in the final system. operating characteristics of a hybrid system are investigated from a simulated system where a turbocharger (microturbine simulator) and a modified fuel cell burner test facility (fuel cell simulator) are employed. The 60kW demonstration unit will be built up and operated to provide the valuable information for the preparation of the final full scale 200kW hybrid system.

This plan was submitted as part of an invited competition for the provincial park planning of Yeonin Mountain, which was held by the Gyeonggi Innovation Corporation in November, 2006. The proposed site is located at Seungan-ri, Gapyung-eup, Gapyung-gun, Gyunggi-do and covers about $150,010m^2$. The main goal of this project is to "Suggest a New Park Paradigm" by shedding old ways of thinking about parks through an integrated development concept. Planning was approached as follows: First, providing an unique theme to the support facilities area of Yeonin Mountain Piovincial Park. To achieve this theme, the Seungan support facilities area was designated to be home to a Seven Colored Theme Garden, currently named the Native Wild-flower Garden, while the Baekdun facilities area is to be centered on a Self-loaming Forest Camp, which will give the chance of a hands-on wildlife experience. With these themes, which create recreational goals that will encourage not only tourism but education as well, the foundation was laid for a multi-purpose park paradigm. Second, Developing a Core Facility Zone. To accomplish the development of a core facility zone, park buildings will be arranged in accordance with an integrated building lay-out for easy access and use, and the facilities specified by design for the Seven Colored Theme Garden are provided for the newly prepared site. This will allow focus on the user's viewpoint instead of the view of the planner or of ease of maintenance.
