  • 본 논문에서는 실시간으로 가상현실의 증강객체에 외부의 힘이 작용할 때 증강된 가상 객체의 동적 모델링 방법을 제시하였다. 가상객체의 자연스러운 움직임을 시뮬레이션 하기 위하여 AR 객체에 적용되는 외부의 힘의 변화에 대하여 Newton의 운동법칙을 적용하여 객체의 움직임을 설명하는 식을 생성하였다. 동적 모델링 과정에서 증강된 객체와 햅틱 장비간의 실질적 상호작용이 발생하며 이때 외부의 힘이 가상객체에 전달된다. 증강된 객체의 고유특성은 강체 혹은 탄성체의 성질을 갖는 모델이다. 강체의 동적 모델링에서는 선형 모멘텀과 각속도 모멘텀을 모두 고려하여 증강된 객체와 햅틱 스틱이 충돌할 때 수행하였다. 비강체의 동적 모델링에 있어서는 탄성체의 변형 모델은 내외의 힘과 제한요소에 자연적으로 반응하기 때문에 물리기반 시뮬레이션 방법을 적용하였다. 증강된 탄성체는 햅틱 인터페이스를 통해 사용자에 의하여 발생하는 힘의 특성과 모델의 고유 특성에 따라 자연스럽게 변형된다. 변형 물체의 모델링을 위하여 Newton의 제 2 운동법칙이라 불리는 질량-스프링 연결 시스템을 적용하였다. 실험을 통하여 증강된 강체와 비강체의 성질을 지닌 가상 객체에 햅틱 장비에 의한 햅틱 상호작용이 발생 할 때 객체의 변환을 자연스럽게 가시화 할 수 있었다.

  • Objective: Middle school girls who belonged to the concerned group in their school assessment were treated by sandplay for relieving their emotional and behavioral difficulties. The purpose of this study was to explore the change of the internal world of the girls through sandplay. Methods: Analytical psychology and sandplay theories were used for this exploration, especially Turner's (2005) content themes in sandplay. The participants were four first-grade girls. Pre-test measures, a 12-session sandplay program, and post-test measures were administered. Results: For the first girl, the initial phase was 1-6 (time trip), the intermediate phase was 7-9 (seeking for an inner island), and the final phase was 10-12 (seeking for a real stone). For the second girl, the initial phase was 1-5 (my heart was like cold weather), the intermediate phase was 6-10 (fallen, sick, and risen), and the final phase was 11-12 (trophy given to me). For the third girl, the initial phase was 1-5 (seeking for oasis), the intermediate phase was 6-10 (difficult trip for climbing with camel), and the final phase was 11-12 (discovering oasis). For the fourth girl, the initial phase was 1-3 (an island drowning shortly ), the intermediate phase was 4-10 (my unknowable mind), and the final phase was 11-12 (a tree growing well). Conclusion: This study showed psychological phenomena in the sandplay of four girls such as opposites and the union of masculinity and femininity as they explored their own identity. Drawing tests and counselling objects indicated positive changes; thus, these findings support the effectiveness of sandplay therapy for transforming the psyche of middle school girls.

  • Background: Scapular winging (SW) could be caused by tightness or weakness of the periscapular muscles. Although data mining techniques are useful in classifying or predicting risk of musculoskeletal disorder, predictive models for risk of musculoskeletal disorder using the results of clinical test or quantitative data are scarce. Objects: This study aimed to (1) investigate the difference between young women with and without SW, (2) establish a predictive model for presence of SW, and (3) determine the cutoff value of each variable for predicting the risk of SW using the decision tree method. Methods: Fifty young female subjects participated in this study. To classify the presence of SW as the outcome variable, scapular protractor strength, elbow flexor strength, shoulder internal rotation, and whether the scapula is in the dominant or nondominant side were determined. Results: The classification tree selected scapular protractor strength, shoulder internal rotation range of motion, and whether the scapula is in the dominant or nondominant side as predictor variables. The classification tree model correctly classified 78.79% (p = 0.02) of the training data set. The accuracy obtained by the classification tree on the test data set was 82.35% (p = 0.04). Conclusion: The classification tree showed acceptable accuracy (82.35%) and high specificity (95.65%) but low sensitivity (54.55%). Based on the predictive model in this study, we suggested that 20% of body weight in scapular protractor strength is a meaningful cutoff value for presence of SW.

  • Vivienne Westwood, the revolutionary cre-ator of Punk fashion(ripped T-shirts, bondage clothes, fetishist accoutrements) was a street fashion designer. Although Westwood's clothes have frequently been described as decadent, degenerate and unwearable, they have also exerted a powerful influence on interntional fashion. Westwood became a fashion designer in the mid-1970s, when he emergence of Punk put London back on the fashion map for the first time since 1965. Just as the Mods, Rockers, and Hippies of the 1960s had embraced par-ticular styles of dress and music, so also did the Punks create their own subculture. The Punk“style in revolt”was a deliberately“re-volting style”that incorporated into fashion various offensive or threatening objects like tampons, razor blades, and lavatory chains. Vivienne Westwood and parter Malcolm McLaren articulated this youth culture, who roots lay in music. A sign is something which stands for some object or idea, while the semiotics are the ex-ternal expression for an internal meaning. Semiotics can be used as a medium of communication between dress and music. A language is simply used for explicit of meaning, while the style of dress and music express the explicative and implicative signs. Peirce's scheme among several theories of the semiotics was chosen for this study, because the Peirce's scheme was the first non-language communication medium between external and internal stages, and readily inter-preted the styles of dress and music. Punk rock was studied at first to identify the style which influenced Vivienne Westwood's works and then Semiotics were used to apply the above results to the 1970s and 1990s for analyzing and interpreting the Vivienne Westwood's works were also interpreted by the symbolic characteristics of Semiotics, because the symbol of semiotics often found at Youth Cults reflected punk rock. The symbol of revolt, decadence, grungy, freedom in Vivienne Wes-twood's works wre determined by using Punk rock's semiotics. This study could conclude that the style of dress and punk rock were able to be interpreted by semiotics.

  • Background: The assessment tool developed in other countries should be translated into Korean language using rigorous methodological approaches in order to be used in Korea. Because these procedures are insufficient for establishing the cross-cultural and linguistic equivalence, the need for statistical methods is raised. The Fullerton Advanced Balance Scale was translated into Korean and the content validity was verified through the back translation method, but the reliability and validity have not yet been proven by statistical methods. Objects: The purpose of this study was to investigate the reliability and validity of the Korean version of the Fullerton Advanced Balance Scale (KFAB) by statistical methods in elderly people. Methods: A total of 97 elderly adults (39 males and 58 females) participated in this study. Internal consistency of the KFAB was measured using Cronbach's alpha and an intraclass correlation coefficient (ICC) was used to assess test-retest reliability between the two measurement sessions. Concurrent validity was measured by comparing the KFAB responses with the Korean version of the Berg Balance Scale (KBBS) using the Spearman correlation coefficient. Construct validity of the KFAB was measured using the exploratory factor analysis to evaluate the unidimensionality of the questionnaire. The significance level was set at ${\alpha}=.05$. Results: The internal consistency of the KFAB was found be adequate with Cronbach's alpha (.96), and test-retest reliability was excellent as evidenced by the high ICC (r=.996). Concurrent validity showed high correlation between the KFAB and KBBS (r=.89, p<.001). Construct validity was evaluated using exploratory factor analysis. The result from Bartlett test of sphericity was statistically significant (p<.001), and the value of Kaiser-Meyer-Olkin measure of sampling adequacy was .93. Exploratory factor analysis revealed the existence of only one dominant factor that explained 76.43% of the variance. Conclusion: The KFAB is a reliable, valid and appropriate tool for measuring the balance functions in elderly people.

  • XML을 이용한 사용자 인터페이스 개발은 플랫폼과 프로그래밍 언어에 독립적이며, 사용자가 배우기 쉽고, 사용하기 쉬운 장점을 가지고 있다. 그러나, 현재까지 개발된 XML 기반 사용자 인터페이스 언어들은 정형화된 모델을 사용하지 않고 있으며, 사용자 인터페이스와 내부 로직의 결합 및 이벤트 처리 부분이 미약한 단점을 가지고 있다. 이러한 문제점을 해결하기 위해서 본 논문에서는 MVP(Model-View-Presenter) 모델을 확장한 EMVP (Extended MVP)를 제시하고, EMVP를 기반으로 사용자 인터페이스를 개발할 수 있는 새로운 XML 응용프로그램인 XUIML을 소개한다. XUIML은 EMVP를 기반으로 인터페이스 형태, 이벤트 처리, 데이타 흐름, 인터페이스와 내부 로직의 결합을 기술할 수 있는 방법을 제공한다 XUIML 시스템은 텍스트 편집기와 그래픽 편집기 및 XUIML을 자바와 C# 코드로 변환할 수 있는 변환기를 제공한다. 한편, XUIML의 그래픽 편집기는 직접 조작 방식을 지원하기 때문에 GUI 디자인 도구와 같은 높은 생산성을 얻을 수 있다.

  • Funology is a compound word with fun and technology which means the products or activity carrying fun and technology at the same time. This is one of the key words that can explain the culture of post-digital generation amongst the post-digital age. The purpose of this study was to provide the creative ideas to develop the fashion designs showing funology concept for the 21st century. As a background of funology trend, general ideas about the post-digital age and the post-digital generation were reviewed. First, funology designs among the industrial products and the funology concepts in the advertisement were examined. And the ways of expression and the meanings of funology fashion designs were extracted by analyzing funology fashion between 2000 S/S and 2008 F/W. The external expression ways of funology fashion in the post-digital age were as follows: parody of popular images, inharmony by the exaggeration or transformation, trompe l'oeil, mixture of the styles shown in the children's wear and the objects of children, patterns with childlike or animation characters, and the graffiti art. The internal meanings contained in the funology fashion were 1) fantasm showing surrealistic funology that was based on the people's pursue of fantasy free from the everyday's severe routine 2) memorism showing nostalgic funology that was based on the pursue of vanishing fear of reality and going back to the childhood. To sum up, fashions showing funology were expressed in various ways in the post-digital age. This will provide the great inspirations for creating the new coming fashions and efficient healing contents for the cold-hearted emotions of nowaday's people.

  • Method : Chronic motor tic or vocal tic disorders are characterized which have one of the two kinds of tics for more than a year. It is characterized chronic motor tic or vocal tic disorders that have one of the two kinds of tics for more than a year. But Tourette's disorder is a disease which has one or more motor tics and vocal tics for more than a year. Contemporary empirical studies have suggested the rate of comorbid attention-deficit hyperactivity disorder(ADHD) or obsessive compulsive disorder(OCD) in children with tic disorders be high. Objects : As society is confusing, tic disorders are increasing. Therefore, determining the treatment strategy in children with tic disorders is very important. So we studied the literatures of traditional chinese medicine about tic disorders and reported the results. Results : The principals for medical treatment were So-gan(疏肝), I-gi(理氣), Sik-pung(熄風), Gin-kyung(鎭痙), Chung-oel(淸熱) etc. Medicines treatment is used more than acupuncture treatment. The herbs are used Uncariae ramulus et Uncus(釣鉤藤), Paeoniae Radix Alba(白芍藥), Poria(白茯岺), Glycyrrhizae Radix(甘草), Bupleuri Radi.x(柴胡), Fossilia ossis Mastodi(龍骨) etc. in the order named. Acupuncture points were used Naegwan(PC6), Shinmuin(HT7), P'ungnyur4(ST40), Paek'oe. (GV20), Chung-wan(CV12), Samumgye(SP6), Kongson(SP4), T'aech'ung(LR3) and so on.

  • Background : Although chronic non-bacterial prostatitis is increasing, it is hard to treat effectively. In western medicine, antimicrobials drug, ${\alpha}$-adreno-ceptor antagonists, anti-inflammatory drugs, tricyclic antidepressants and anticholinergic agents are used commonly, but chronic prostatitis/chronic pelvic pain syndromes is confusing and frustrating for urologist. IDS(Indongsoyeom-bang) is used in treatment of chronic prostatitis/chronic pelvic pain syndromes. And it is reported that GLS(Gleditsiae spina) and TOF(Toosendan fructus) components of IDS have significant effect on protection of the glandular epithelial cells. Objective : In this study was conducted to investigate the therapeutic effects and action machanism of IDS in the rat model of non-bacterial prostatitis induced by castration and testosterone treatment. Methods : We observed six experimental objects of normal group, control group, testosterone group, and IDS 50 mg/kg, 200mg/kg, 400mg/kg group. Rats were treated with 17 ${\beta}$-estradiol after castration for induction of experimental non-bacterial prostatitis, which is similar to human chronic prostatitis in histophatological profiles. IDS and testosterone were administered as an experimental specimen and a positive control, respectively. The prostates were evaluated by histological parameters including the epithelial score and epithelio-stromal ratio for glandular damage. Also, the prostates were observed by Hematological alterations of WBC, RBC, hemoglobin and platelet. Results : While prostates of control rats revealed severe acinar gland atrophy and stromal proliferation, the rats treated with IDS-50 showed a diminished range of the tissue damage. Epithelial score was improved in IDS than that of the control. The epithelio-stromal ratio was lower in IDS when compared to that of the control. Also, the examination of bloods were not observed hematological change. Conclusion : These finding suggests that IDS may protects the glandular epithelial cells. We concluded that IDS could be a useful remedy agent for treating chronic non-bacterial prostatitis.
