아동정책은 주로 보건복지부에서 요보호아동을 위한 사후적인 복지제도를 중심으로 집행된 반면 청소년정책은 국가청소년위원회에서 일반청소년을 위한 육성제도를 중심으로 실시되어 왔다. 하지만 아동청소년정책의 부처별 산발적 추진으로 인해 서비스 중복 현상이 나타나고 정책의 체계적 집행이 부족하였다. 따라서 일관성 있는 아동청소년정책의 추진을 위해 이명박 정부에서는 국가청소년위원회를 보건복지가족부로 흡수하면서 아동청소년정책의 통합작업을 진행하고 있다. 본 연구에서는 아동청소년정책에서 통합의 의미가 무엇인지, 이명박 정부의 전달체계 통합방안의 문제를 검토하고 이를 보완하기 위한 방안이 무엇인지를 제언하였다. 바람직한 통합정책을 추진하기 위해서는 부처통합에 따른 보건복지가족부내의 아동정책과 청소년정책의 단순 결합을 넘어서 국가 전체의 인적자원개발계획과 경제정책을 고려하여 통합적인 아동청소년정책이 수립되도록 전면적인 재설계가 필요하다. 또한 정책대상의 비효율적인 중복이 강조되기보다는 정책의 공공성과 적정예산의 확보를 위해 아동청소년정책예산의 획기적인 증가가 선결되어야 한다는 점이 강조되었다.

본 연구에서는 순수한 ${\alpha}^{{\prime}{\prime}}-Fe_{16}N_2$의 띠구조와 자기결정이방성에 대한 총 퍼텐셜 선형보강 평면파(Full-potential Linearized Augmented Plane Wave; FLAPW) 방법을 이용하여 연구하였다. 혼성화된 질소원자로 인해 Fe(4e), Fe(8h) 영역의 자기모멘트가 감소되었지만 z-축 방향의 격자 확장으로 인해 Fe(4d) 영역의 자기모멘트가 매우 커짐을 확인할 수 있었다. 각각의 Fe 영역들(4d, 4e, 8h) 스핀 자기모멘트들은 이전에 알려진 값들과 잘 일치함을 알 수 있다. 정방정계 왜곡으로 인해 $0.58 MJ/m^3$의 매우 큰 일축이방성상수를 구할 수 있었다. 게다가 1.76 MA/m의 매우 큰 자화량 또한 얻을 수 있었다. 또한 순수한 ${\alpha}^{{\prime}{\prime}}-Fe_{16}N_2$의 6.51 kOe의 예측 보자력과 71.7 MGOe의 최대에너지적을 얻을 수 있었다. 이러한 결과는 ${\alpha}^{{\prime}{\prime}}-Fe_{16}N_2$ 구조가 희토류 대체 영구자석으로 이용될 가능성이 있다는 것을 의미한다.

The formation process and the dynamical properties of a large-scale quasi-circular flare ribbon were investigated using the SDO AIA and HMI data along with data from RHESSI and SOT. Within one hour time interval, two subsequent M-class flares were detected from the NOAA 12371 that had a ${\beta}{\gamma}{\delta}$ configuration with one bipolar sunspot group in the east and one unipolar spot in the west embedded in a decayed magnetic field. Earlier M2.0 flare was associated with a coronal loop eruption, and a two-ribbon structure formed within the bipolar sunspot group. On the other hand, the later M2.6 flare was associated with a halo CME, and a quasi-circular ribbon developed encircling the full active region. The observed quasi-circular ribbon was strikingly large in size spanning 650" in north-south and 500" in east-west direction. It showed the well-known sequential brightening in the clockwise direction during the decay phase of the M2.6 flare at the estimated speed of 160.7 km s-1. The quasi-circular ribbon also showed the radial expansion, especially in the southern part. Interestingly, at the time of the later M2.6 flare, the third flare ribbon parallel to the early two-ribbon structure also developed near the unipolar sunspot, then showed a typical separation in pair with the eastern most ribbon of the early two ribbons. The potential field reconstruction based on the PFSS model showed a fan shaped magnetic configuration including fan-like field lines stemming from the unipolar spot and fanning out toward the background decayed field. This large-scale fan-like field overarched full active region, and the footpoints of fan-like field lines were co-spatial with the observed quasi-circular ribbon. From the NLFF magnetic field reconstruction, we confirmed the existence of a twisted flux rope structure in the bipolar spot group before the first M2.0 flare. Hard X-ray emission signatures were detected at the site of twisted flux rope during the pre-flare phase of the M2.0 flare. Based on the analysis of both two-ribbon structure and quasi-circular ribbon, we suggest that a tether-cutting reconnection between sheared arcade overarching the twisted flux rope embedded in a fan-like magnetic field may have triggered the first M2.0 flare, then secondary M2.6 flare was introduced by the fan-spine reconnection because of the interaction between the expanding field and the nearby quasi-null and formed the observed large-scale quasi-circular flare ribbon.

Purpose: In this study the present status of the practicum in Fundamentals of Nursing and test for student competency in nursing skills were surveyed. Method: Participants included 72 nursing schools. A structured questionnaire was used for data collection and SPSS 17.0 for data analysis. Results: Credits for Fundamentals of Nursing, credits for practicum and hours per credit were 2.93, 7.34, and 2.14 respectively. Number of students per practice unit, full time assistants and students per assistant were 28.6, 0.6, and 20.2 respectively. Utilization of CPX room and OSCE room for practice was 5.6%, and 9.7% respectively. Of the school, 32.0% included clinical practice in the practicum. 90.3% provided an open lab but only 48.4% had full-time assistants for these clinical practice areas. Testing for nursing skill competency was performed twice a semester in most schools. Utilization of standard patients and high fidelity models for testing was 8.3%, and 23.6% respectively. The test was thought to be inappropriate in 33.4% of the schools. Conclusions: The results suggest that to improve the outcomes, the practicum for Fundamentals of Nursing needs to be changed to include expansion of facilities and human resources, utilization of standard patients and high fidelity models and development of appropriate test methods.

함정의 수동소나는 여러 개의 지향성과 무지향성 센서로 구성되어 있다. 함정 소나에 수신되는 음향 신호를 모의할 때, 일반적으로 임의의 소음원으로부터 소나에 장착된 모든 센서간의 음파 전달 모델링이 필요하다. 그러나 모든 센서에 대한 통합적인 계산은 시간이 많이 소모되며 소나 시뮬레이터의 성능을 저하시킨다. 본 연구에서는 음선 정보가 알려진 기준 센서가 존재한다고 할 때 그에 인접한 센서 위치에서의 소나 신호를 추정하는 근사적인 방법을 제안한다. 이 방법은 음선의 도달 시간에 대한 테일러 급수를 이용하여 개발되었으며 소나 개구면에 대한 Fraunhofer와 Fresnel 근사와 유사하다. 제안된 기법을 검증하기 위해 수동 소나에 대해 여러 수치실험이 수행되었다. 2차 항까지 테일러 근사를 적용한 근사법이 보다 우수한 결과를 보였다. 추가적으로 각각의 근사 해에 대한 오차 한계가 제시되었다.

With the advent of the new political regime of Jong Un Kim, North Korea is undergoing many changes, with its main motivation being economic growth. This study aims to identify the changes in clothing in North Korea under the new political climate. The research conducted a review on literature and empirical study. For literature review, books and papers from studies related to North Korea have been reviewed. For the empirical part, interviews with diverse class of North Korean refugees including Hanawon, videos on TV, 1,100 pictures and related articles from newspapers and Internet have been collected. Through this analysis, the study found that subtle changes in North Korean fashion started prior to the Jong Un Kim's regime, but has become full-blown since Kim's assumption of power. This proves that the country is not yet independent from its political situation. The results are as follows: First, the appearance of Ri Sol-ju has liberalized the fashion concept of North Korean women, and the popularity of her trademark style has actually contributed to a more amicable image for Kim. Second, the "Hallyu" style has spread to North Korea through various channels, and has started new trends. Third, the diversification of fashion styles has been greatly accelerated in accordance with the expansion of market, resulting from the economic revitalization policy. Last of all, Jong Un Kim's direct orders concerning fashion have resulted in some significant changes. The sophisticated uniforms of flight attendants and the development of luxury cosmetics being prime examples. As studies on this subject are extremely rare, this research is significant to identify the changes on the clothing culture under Jong Un Kim's regime, and to present an expanded view, as the two countries work towards an united Korea.

G-code, another name of ISO6983, has been a popular commanding language for operating machine tools. This G-code, however, limits the usage of today's fast evolving high-performance hardware. For intelligent machines, the communications between machine and CAD/CAM departments become important, but the loss of information during generating G-code makes the production department isolated. The new standard for operating machine tools, named STEP-NC is just about to be standardized as ISO14649. As this new standard stores CAD/CAM information as well as operation commands of CNC machines, and this characteristic makes this machine able to exchange information with other departments. In this research, the new CNC machine operated by STEP-NC was built and tested. Unlike other prototypes of STEP-NC milling machines, this system uses the STEP-NC file in XML file form as data input. This machine loads information from XML file and deals with XML file structure. It is possible for this machine to exchange information to other databases using XML. The STEP-NC milling machines in this research loads information from the XML file, makes tool paths for two5D features with information of STEP-NC, and machines automatically without making G-code. All software is programmed with Visual $C^{++}$, and the milling machine is built with table milling machine, step motors, and motion control board for PC that can be directly controlled by Visual $C^{++}$ commands. All software and hardware modules are independent from each other; it allows convenient substitution and expansion of the milling machine. Example 1 in ISO14649-11 having the full geometry and machining information and example 2 having only the geometry and tool information were used to test the automatic machining capability of this system.

Recently, it appears several counterproposals about desirable figures of urban architecture. All of them proposes 'publicity' with cohernt tendency. The reason why it concentrates quantitative expansion of city without united design by urban plannar is that neglect quality values of city. As a solution of poor environment, there cue out the various efforts, about problem of each building, problem of city space, problem of laws and so forth. The reason why necessity of public space was embossed in that architecture extend the activity of citizen and make up the city space. But, each building pursues the private interest, so it is difficult to secure a public space with a high hand. Thus, architecture law has been revised in 1991 and bring the system of open space to match up the publicity and the private interest. Actually, western country brought it and obtained excellent results. While quantity of open space have increased since 1991, a lot of problems revealed in real usage and quality. By means of problem's solution, this study focus on the diversion of recognition for necessity of various open space. In result, on the occasion of approach and openess, except for several building, most glass a facade and the pedestrian can approach easily. Moreover, office buildings near the subway station connected with their low floor. So, the office buildings give openess to pedestrian and a people can approach easily to the buildings. On the occasion of amenity, most have bank and lobby on the first floor and have facilities on the underground floor. It leave open. But the reason why they have bank and lobby is that the space is dry and boring(without elements of nature and rest space). Hence, to make a space full of vitality, it have to plan various design elements and facilities. First of all, plan of indoor public space have to make up facility for the public interest. This study is basic investigation for necessity of indoor public space and through the survey of office buildings, it analyze the character of plan and find out the method of publicity's realization.
