Being called 'the period of diversity', the 21st century is taking on a new aspect which is different from the past where a certain phenomenon of a specific area was prescribed as one representative icon of a period. In particular, the globalization culture acted as the catalyst to accept such diversity and it appeared as a new culture code, 'fusion' throughout society and culture. Especially, unlike two-hour movies, the recent drama $\lceil$Gung$\rfloor$ showed various fusion style costume over a period of three months and created a sensation of fusion style costume. Therefore, this study is aimed at investigating fusion style costume by selecting the TV drama $\lceil$Gung$\rfloor$ which was on the air in 2006. Though various studies on fusion style costume, which is becoming a new culture code, have been conducted, this study is meaningful in that it's time to conduct a new study through a popular TV drama. Based on preceding studies on fusion style, the elements of fusion style were analyzed by capturing the most frequently exposed heroine's costume, and new design development introducing fusion elements was attempted for empirical studies. The study results are as follows. First, it was found that the fusion trend is a culture code which already spread to the public and is shown in the fashion in various ways. Second, the drama $\lceil$Gung$\rfloor$, is commented as a new dram which introduced the fusion style costume into Korea through a modern version of constitutional monarchy and is commented as a medium which created an interest in the fusion costume among the public as well. Third, new trend elements of the fusion style could be derived through empirical studies by design development.

This study evaluates the relationship among the evaluation structure of morphological elements, the satisfaction on exterior elements, and the image evaluation for the campus landmarks by campus type. The investigation results are summarized as follows. 1) The university headquarter was nominated as the university landmark, and the main reason for the nomination was the building's historic and locational value. 2) Of the morphological elements of the campus landmark, 'proportion and balance' and 'harmony and order' were deemed important, while 'diversity' was deemed less important. 3) For the satisfaction on the facility's exterior elements, the evaluation structure was different for each university. However, the factor of 'location of the facility' was deemed the biggest factor for satisfaction for all universities, while the facility's 'color and material' were found to be the most dissatisfying factors. 4) The image evaluation on the facility was different for each university. Although there was a strong skeptical image about 'liveliness', there was a very positive image about 'elegance' and 'scale'. 5) On the relationship between the satisfaction on exterior elements and the image evaluation, there was a different evaluation structure for each university. 'Facility's color and exterior material' were the main elements which improved the overall image of the facility. Thus, the study results strongly suggest that an important task is to determine the maintenance direction through the emphasis on the relationship between exterior elements and image satisfaction for each university.

This paper proposes a miniaturized high-isolation diversity antenna for wearable wireless body area network (WBAN) applications. An inverted-F type radiating element is used to reduce the overall dimension of the proposed antenna to $30mm{\times}30mm{\times}2.5mm$. The antenna performance on the human body phantom is analyzed through simulation and the performance of the fabricated antenna is verified by comparing the measured data with that of the simulation when the antenna is placed on a semi-solid flat phantom with equivalent electrical properties of a human body. The fabricated antenna has a 10 dB return loss bandwidth over the Industrial Scientific Medical (ISM) band from 2.35 GHz to 2.71 GHz and isolation is higher than 28 dB at 2.45 GHz. The measured peak gain of antenna elements # 1 and # 2 is -0.43 dBi and -0.54 dBi, respectively. Performance parameters are analyzed, including envelope correlation coefficient (ECC), mean effective gain (MEG), and the MEG ratio. In addition, the specific absorption ratio (SAR) distributions of the proposed antenna are measured for consideration in use.

본 연구에서는 2009개정 교육과정의 중학교 과학교과서에 포함된 탐구 활동이 기존 과학교육에서 강조되어왔던 탐구 기능과 구체적 학생 활동이 강조되는 NGSS의 8가지 과학 실천 측면에서 상호 분석되었을 때 어떤 특성을 나타내는지 생명과학 단원을 중심으로 분석하였다. 분석 결과 학년 구분 없이 탐구 기능에서는 '추리', 관찰', '분류' 순으로 많이 치중되었고, 과학 실천에서는 '자료 분석하고 해석하기'와 '설명구성하고 문제해결 고안하기'에 치우쳐 있었다. 이를 통해 중학교 교과서 내 생명과학 탐구 활동이 탐구 기능뿐만 아니라 과학 실천 요소에서도 다양성이 부족하며 제시하는 활동의 목표가 한정적이라는 것을 보여주었다. 또한 과학탐구 기능과 과학 실천 요소 각 상호 매칭작업을 통해 탐구 기능 중심에서 과학 실천으로의 이행 시 내용 관련성을 검토하고 교과서의 탐구 활동에서 보이는 결과와 비교 분석한 결과 사전 매칭분석에 비해 교과서 내 탐구 활동의 결과가 대체적으로 기초탐구-자료해석/기초탐구-설명고안에 치우쳐 있어서 단조롭게 매칭 되었다. 이는 교과서에 제시된 활동내용의 다양성이 부족함을 보여주는 결과라고 할 수 있다. 본 연구에서는 2009개정 교육과정의 교과서 분석을 통해 단순하고 다양성이 부족한 탐구 활동에서 벗어나 2015개정 교육과정을 구현해나가는 과정에 다양한 과학 실천 요소를 포함시키도록 하는 노력이 절실하게 요구됨을 제언한다.

The significance of this research lies in the analysis of that appears in the comedy . It also aims to propose conceptual and analytical costume designs that emphasize the formal aspects of play by reflecting on the comical elements simultaneously. , the subject of this study, was played on November 12, 2009 at the Small Theater (Dalohreum Theater) in the National Theater as a celebration of the 40th anniversary of Suwon Women's College. The costumes were designed by this researcher and were produced in collaboration with the Creative Performances Research Institute (Suwon Women's College). The comic elements were categorized into deconstruction, deviation and unexpectedness according to previous studies on the humorous nature of comedy, and their aesthetic meanings were applied to the costumes. The designs that reflect the comic elements are as follows. The costume design reflecting deconstruction is a way that disassembles and recombines constructive aspects of clothing. It consists of seam margins outside or just left disassembled without sewing, dismantling the boundary of outerwear and underwear. The costume design reflects deviation because reformed shapes of collars, the variation of length and closure of skirts deviate from the traditional style. These are designed by distorting traditional designs with deviation and transcend of tradition. The costume designs the reflect unexpectedness integrates both tradition and the contemporary, and use materials of diversity and heterogeneity, and these are composed of external formats the result from incongruity. Because comic elements are metaphysical concepts that carry meanings that are difficult to define according to the country and period, it is required to analyze, organize and utilize their characteristics and meanings of each period. Since this study analyzed the comical elements of a play and applied them to costume design, it is hoped that a follow-up study of analytical costume design is be done, and that more diverse and more creative costume designs are in the next generation.

본 논문은 DS/CDMA 신호 환경에서 동작하는 배열 안테나 시스템에서 다이버시티 이득을 이용하여 동기 성능을 향상시키는 탐색기를 제안한다. 제안한 PN 동기 검출 방법은, 대부분의 CDMA 기반 신호 환경에서 각 안테나 소자에 유기되는 간섭자의 실수-부 성분과 허수-부 성분이 서로 독립적인 가우시안 채널로 모델링할 수 있다는 사실에 근거를 둔다. 제안한 PN 동기 검출 방법은, 모든 PN 위상 오프셋에서 동기 에너지 값을 구하기 위해, 다수의 수신 신호를 안테나 별로 수신기의 PN과 독립적으로 코릴레이션하여 non-코히런트하게 선형 결합하는 단계인 검색 (searching) 단계와 구한 동기 에너지 값을 락-검출기에서 설정한 최적 기준값과 비교하여 동기 성공 여부를 판단하는 증명 (verification) 단계로 이루어진 single-dwell 방식이다. 본 논문에서는 평균 PN 동기 획득 시간 (Mean Acquisition Time)을 결정짓는 중요한 요소인 다이버시티 이득의 영향에 대해서 분석한다 일반적으로, 평균 PN 동기 획득 시간은 배열 안테나 소자의 수가 증가할수록 감소한다고 알려져 있다. 그러나, 다이버시티 차수 증가에 의한 PN 동기 획득 성능 개선은 포화된다. 따라서, 배열 안테나 수신기에서는 수신기의 동작 SNR 범위와 목표 검출 확률 $P_D$ 및 오-경보 확률 $P_{FA}$를 고려하여, 평균 PN 동기 획득 시간을 최소화하기 위한 최적의 배열 안테나 설계가 필요하다. 제안한 PN 동기 검출 방법의 성능은 주파수 선택적 레일레이 페이딩 채널에서 분석하였으며, 기존 단일 안테나에서의 PN 동기 획득 방법보다 우수함을 검출 확률 $P_D$ 및 오-경보 확률 $P_{FA}$항목에서 검증하였다.
