In this paper, we review some aspects of geometry for charged rotating black holes which are formed from the gravitational collapse of a massive spinning star with electric charge. We also introduce the computation of entropy for black holes from loop quantum gravity which is a quantum theory of gravity based on Einstein's theory of general relativity.

Fashion is a field that responds sensitively to social and cultural atmospheres, brings about constant change due to consumer demand for new items in new fashion trends and in the latest design. The fashion industry tries to predict what kind of clothing the customers desires and produces fashion products according to trend information stated by fashion information services. This research analyses the relativity between the trends stated in the fashion information books and what consumer accept, and with this information find the application of trend information books in the planning of domestic woman's clothing. The used information books were based on Samsung Fashion Institute and Interfashion Planning, Inc. The 02/03 F/W season emphasized restoration-romantic, nostalgic mood themes. Fashion trend information and consumer acceptance condition tend to concentrate on trend themes given tv fashion information companies. In other words, $Sincere\;girl(39.04\%){\to}Frontier\;girl(34.92\%){\to}Dark\;lady(18.43\%){\to}Lady\;belle(7.59\%)$ in this order Also when looking into the consumer's wearing, no one theme appears by itself and the themes are mixed accordingly to one's lifestyle and sensibility. Accordingly fashion information organizations must provide precise fashion trends according to consumer sensibility & consumption and also compare trend information to consumer fashion trends each season. With this precise information the planned design plans will help the domestic fashion markets, which are gradually overrun by foreign brands, develop a unique and original fashion product that meets consumer sensitivity needs, and develop a new stepping stone for fashion companies and the relative fashion industry and furthermore contribute to the advancement of overseas markets.

연관성규칙은 대용량 데이터베이스에서 각 항목들 간의 관련성을 찾아내는 기법으로 둘 또는 그 이상의 품목들 사이의 지지도, 신뢰도, 향상도를 바탕으로 관련성 여부를 측정한다. 연관성규칙에서는 일반적으로 사용하는 연관성규칙 이외에 연관성규칙의 효율성을 개선하기 위하여 여러 가지 제약기반 연관성규칙의 연구가 활발하게 진행되고 있다. 연관성규칙 생성 시, 종종 많은 규칙들을 발견할 수 있다. 이는 변수들 간에 우연히 관련성이 높게 나타나는 경우가 존재할 수 있고 매개변수에 의하여 직접적인 관련성이 없는 규칙을 발견할 수도 있다. 이에 본 논문에서는 연관성규칙에서 매개변수에 의한 의미 없는 규칙의 발견에 관하여 연구하고자 한다. 본 연구 결과는 연관성 규칙에서 생성된 규칙에 대한 관련성을 보다 정확하게 이해할 수 있도록 함으로써 결과의 해석을 보다 명확하게 할 수 있다.

Background and purpose: The purpose of this study is to review the recent achievements on ryodoraku and suggest new ryodoraku studies. Methods: The study papers related with ryodoraku, published in foreign countries and Korea up to the present, were collected first by internet search & journal. And then the collected papers were classified and summarized. Results and Conclusion: There are three study trends. One is finding some effect and analysis for some symptoms, another is finding a distinguishing mark and a diagnostic index, and the other is raising several points & providing solution & studying about relativity with another diagnosis. Some studies finding some effect and analysis for some symptoms are to be classified into four items(1. effect of drugs medication. 2. effect of ryodoraku therapy. 3. effect of other treatments. 4. effect of other treatments with ryodoraku therapy). Other studies finding a distinguishing mark and a diagnostic index are to be classified into two items(1. diagnostic index of symptoms. 2. distinguishing mark of disease). The other studies are to be classified into three items(1. ryodoraku introduction and raising several points at issue. 2. improvement machinery and tools. 3. studying about relativity with another diagnosis). Finally we need solving the ryodoraku problems(the condition of measurement and reproducibility, relation with Kyung-rak(經絡) and Ryodoraku, the reason of Ryodoraku points producing and etc.).

Objectives : This study investigated using National Institutes of Health Strokes Scale in acute and subacute stroke patients and evaluated relativity of pulse pattern to NIHSS. Methods : 104 acute and subacute stroke patients were selected from 4 oriental medical hospitals from April 2007 to May 2007. The patients were admitted to hospital within 1 month after stroke. Pulse feeling diagnosis was done by oriental medical doctor and classified into 7 subtypes. Results : There were significant results statistically between slow/rapid pulse and NIHSS score in the male group; in the female group, there were no significant results statistically but the results showed that slow pulse has lower NIHSS score than rapid pulse. Patients with surging pulse had lower NIHSS score than the other patients. Another pulse pattern had no relativity to NIHSS score.

우리나라의 과학과 교육과정이 학생들에게 가해지는 학습 부담을 줄이기 위해 '학습량의 적정화'를 지속적으로 추진하고 있는 것과는 달리, IB DP는 학습량이 많을 뿐 아니라 정량적인 계산을 필요로 하는 내용을 상당 부분 포함하고 있음에도 불구하고 많은 국가에서 선택하고 있으며 IB를 선택하는 학교의 수는 지속적으로 증가하고 있다. 이에 본 연구에서는 2015 개정 교육과정과 IB DP의 물리학 교과서에서 다루는 '상대성 이론' 단원을 중심으로 물리학 교과서의 단원 구성 및 성취기준, 학습 요소, 수식을 비교하고, 우리나라의 수능 문항과 IB DP의 EA 평가 문항을 분석함으로써 우리나라의 과학과 교육과정 및 교과서와 관련한 시사점을 제시하였다.

Analyzed the subject of ‘To heart' meridian system(向心服系), and 'Circulating' meridian system(備環服系), and considered relativity between the circulating pattern of the channels, the collaterals and the circulating distinction YoungGi (營氣), WiGi(衛氣). The subject of 'To heart' meridian system is WiGi, and this system is similiar to the moving pattern of the fifteen major collaterals(十五絡服). The subject of 'Circulating' meridian system is YoungGi, and this system is same with the moving pattern of the twelve regular channels(十二經脈). YoungGi and WiGi have the same origin, and they are intrinsic one thing with functional ambivalency. It is WiGi, the subject of the movement of Collateral, because it is identical the moving pattern of Collaterals(絡服) and that of WiGi as the subject of the movement of Collateral. It is YoungGi, the subject of movement of Channel because it is identical the moving pattern of Channels(經服) and that of YoungGi. It can be defined that Wigi as the subject of the movement of Collateral, also YoungGi as the subject of movement of Channel, but that is from i 염 function and action, there's no need to be separated within the framework of going through Meridian. YoungSuBosa(迎隨補鴻) in acupuncture, defines its basis not only on the moving direction of YoungGi, but on combinated difference between the directions, moments, and sex. Until now it is under discussion the rights and wrongs, It's not contradictory concept between two basis of YoungSuBoSa, from the thought the distinct movement of WiGi and the circulation pattern of Collaterals have no specified directions.

Gravitational waves are predicted by the Einstein's theory of General Relativity. The direct detection of gravitational waves is one of the most challenging tasks in modern science and engineering due to the 'weak' nature of gravity. Recent development of the laser interferometer technology, however, makes it possible to build a detector on Earth that is sensitive up to 100-1000 Mpc for strong sources. It implies an expected detection rate of neutron star mergers, which are one of the most important targets for ground-based detectors, ranges between a few to a few hundred per year. Therefore, we expect that the gravitational-wave observation will be routine within several years. Strongest gravitational-wave sources include tight binaries composed of compact objects, supernova explosions, gamma-ray bursts, mergers of supermassive black holes, etc. Together with the electromagnetic waves, the gravitational wave observation will allow us to explore the most exotic nature of astrophysical objects as well as the very early evolution of the universe. This review provides a comprehensive overview of the theory of gravitational waves, principles of detections, gravitational-wave detectors, astrophysical sources of gravitational waves, and future prospects.

본 연구는 탈근대의 건축 공간을 고정되지 않고 지속적인 변화의 개념으로 보고, 변화하는 관계 네트워크로 건축 내 공간 요소를 이해하는 것을 목표로 한다. 연구의 목적은 관계성이라는 관점에서 렘 콜하스와 SANAA의 작품에 나타난 공간적 특성을 밝힘과 동시에 두 건축가의 공간구성 전략을 분석하는 것이다. 연구의 방법은 관계성의 대한 이론적 고찰을 통해 비고정적 관계성의 의미를 정의한 후 렘 콜하스와 SANAA의 건축적 접근방법에 대해 살펴보았다. 관계성을 공간의 프로그램, 환경, 사용자 그리고 가구와 집기로 구분하여 두 건축가의 작품 분석하였다. 결과적으로 두 건축가 모두 조직화에 의해 경직된 프로그램을 거부하고 가능성이 내재된 관계성을 건축공간 활성화 목적으로 활용하고 있다는 점에서는 유사하지만, 렘 콜하스는 사용자의 행위유발 기제의 전략을 사용하고 있는 반면, SANAA는 사용자의 자율적 행위를 담는 이완공간의 전략을 사용하고 있음을 확인할 수 있었다.
