Purpose: The study compared the rest-activity rhythm and sleep pattern of elderly with young group. Methods: The subjects were 22 over than 65 years old and 23 under 65 years old. An actigraph, sleep diary, Pittsburgh Sleep Quality Index and Insomnia Severity Index scale were used as measurement tools for this study. The data were analyzed with $x^2$, Lamda test, t-test and correlation with SPSS 15.0 program. Results: The elderly had lower curve than the young group in rest-activity rhythm on each time zone. In particular, the elderly group had lower rest-activity rhythm curve of 8, 9, 14, 18, 19, 20, 21, 22 and 23 time zone than those of young group. Sleep pattern had statistical difference in the total sleep time, PSQI and insomnia. Total sleep time of elderly had lower score and PSQI and Insomnia had higher score than young group. Age had correlation with rest-activity rhythm, sleep efficiency, PSQI and insomnia. Conclusion: Rest-activity rhythm of the elderly showed an increase in activity in the early morning because of earlier get up than the young group and an decrease in activity in the afternoon because of taking a nap at this time. Elderly sleep was that total sleep time increased but sleep efficiency decreased and insomnia intensified. This sleep pattern was related to age and rest-activity rhythm.

The purpose of this study is to objectively explain the visual sensibility of clothing pattern and develop the design of clothing pattern that satisfies the consumer's sensibility. The photos stimuli on clothing pattern are divided into source, presentation, layout and are composed of each 6 photos per chapter totally 48 photos and semantic differential bi-polar scales are consist of 27 couples sensibility words. The subjects were 400 females in the twenties. Data were analyzed by SAS. The major finds were as follows: 1. As a result of the factor analysis, 4 factors of visual sensibility were consist of Coordination, Hardness and Softness, Attention, Rhythm. 2. As to the difference of visual sensibility based on the composition of clothing pattern, there were differences Hardness and Softness, Rhythm by source and there were significant differences among 4 factors by presentation and layout. 3. According to the age and education level, there were significant differences in Attention, Rhythm and according to the consuming areas, there were significant differences in Coordination, Rhythm. 4. According to sensibility positioning, The clothing pattern was classified as soft-hard, simple-complicated. 5. As a result of the regression analysis, preference, consuming desire and satisfaction appears to be closely related. Good quality is related with total clothing image which is brought about composition of clothing pattern.

Objectives: The researchers investigated the relationship between sleep pattern (circadian rhythm/sleep deprivation), eating habit, and the perceived skin condition of female adults, in orders to provide valuable information to women who want to maintain healthy skin and professionals in health promotion. Methods: The participants were 297 female adults whose ages ranged from 20 to 60 (M=35.14, SD=10.37). The questionnaires and psychological tests used in this research included the following: Circadian Rhythm Questionnaire, Sleep Deprivation Scale, Eating Habit Questionnaire, Skin Condition Questionnaire, Scale for Perceived Skin Health. Results: Results indicated that evening type women had more fatty skin and felt their skins less healthier than morning type. Although women who did not deprived their sleep had more fatty and sensitive skin and felt their skins less healthier than women who deprived their sleep, sleep deprivation was positively related to the morningness, and the morningness was negatively related to the preference of fatty and spicy foods. Only the preference of fatty foods among eating habit was positively related to the fatty and sensitive skin, and negatively to the perceived skin health. Regression analyses with circadian rhythm and the preference of fatty foods revealed that only circadian rhythm was significant predictor for the fatty skin, while the preference of fatty foods was only significant predictor for the sensitive skin and the perceived skin health. And, circadian rhythm and the preference of fatty foods accounted for around 12.0% variance of the fatty skin. Conclusion: This study reiterates the roles of fatty foods on skin health, and found the role of circadian rhythm on skin health, and it is needed to explore the relationship between sleep deprivation and skin condition further. These results may provide useful information for health practitioners.

Purpose: In this study rest-activity rhythm, sleep pattern and quality of life of patients with restless legs syndrome were compared with those of a normal group. Methods: The participants in this study were 36 patients with restless legs syndrome diagnosed by a neurologist and 36 participants in the normal group. An actigraph, sleep diary, Pittsburgh Sleep Quality Index and Insomnia Severity Index scale were used as measurement tools for the study. Chi-square test, Lamda test, t-test and Kendall's correlation with SPSS 12.0 program were used to analyze the data. Results: Patients with restless legs syndrome had a higher rest-activity rhythm curve of Least 5 hr's activity(L5) and Most 10 hr's activity(M10) than those of normal group and sleep problems included decreased sleep efficiency and increased sleep latency, wake time and number of awakenings. The scores for the subscales of quality of life in patients with restless legs syndrome were lower than the normal group for general health, physical functioning, role limitations due to emotional problems, role limitation due to physical problems, social functioning, bodily pain, vitality and mental health. Conclusion: The results suggest that further studies are needed to identify rest-activity rhythm according to symptom severity and to develop nursing interventions which consider rest-activity rhythm.

최근 방송의 디지털화에 따라 수많은 채널의 수용이 가능하게 되어, 현재와 같이 신문의 방송편성표를 보고 사용자가 원하는 프로그램의 시작 시간을 알아내는 것은 힘들어 졌다. 디지털방송에서는 신문 방송 편성표와 같은 기능을 하는 방송 프로그램에 대한 정보를 보여주는 EPG(Electronic Program Guide)를 제공하고 있다. 현재 서비스되고 있는 EPG를 보면, 프로그램의 시작 시간을 GUI로 사용자가 쉽게 알아 볼 수 있어 하고 있어 신문 편성표나 인터넷으로 제공되는 각 방송국의 편성표와 달리 TV 화면에서 프로그램 정보를 검색할 수 있어 편리해졌다. 그러나 이 EPG에서 제공되는 시간은 매우 부정확하기 때문에 시청자가 불편을 느낄 수 있다. 본 논문에서는 방송의 시작 시간을 정확히 알아내어 EPG를 정확히 갱신하는데 목적이 있다. 이를 위해 방송의 시작부분을 미리 저장한 후, 시작 부분을 Visual Rhythm을 이용해 shot들을 추출하여 데이터베이스를 구성하고, 이와 같은 방식으로 방송 스트림의 shot들도 추출하여 데이터베이스와의 Pattern Matching을 통해 보다 정확한 방송시간으로 EPG를 갱신하고자 한다.

Objectives: To determine treatment effects of a combination of interpersonal and social rhythm therapy and Korean medicine for a patient with major depressive episode of bipolar II disorder. Methods: A patient was treated with Korean medicine (acupuncture, herbal medicine, etc.) and interpersonal and social rhythm therapy (IPSRT) for four months. Pattern identification for depressive mood and sleep associated symptoms was evaluated using Patient Health Questionnaire-9 (PHQ-9) and Social rhythm metric II-5 (SRM II-5). Results: At the end of the treatment, depression and delayed sleep symptoms were improved and social rhythm was recovered to the regular range. The patient acquired an insight to his interpersonal tensions and conflicts. Conclusions: Korean medicine in combination with interpersonal and social rhythm therapy can be used to treat patients with major depressive episode of bipolar II disorder. More cases are needed to develop guidelines for treating bipolar disorder.

An emphasis on teaching suprasegmental features of English, specifically English rhythm, is essential in order to improve the 'intelligibility' of the pronunciation of Korean EFL learners among interlocutors who use English as a Lingua Franca(ELF). By redefining the ELF suggested by Jenkins (2000, 2002), this paper argues that Lingua Franca Core (LFC) must include suprasegmental features such as 'stress-based rhythm' and word stress. However, because 'isochrony' is difficult to measure in a foot, the rhythm unit must be expanded to an intonational phrase which has prominence in it and the rhythm of the unit can be measured by calculating the duration of each segment in context The rhythmic pattern of Korean learners of English and that of native speakers or other non-native English speakers can then be calculated and compared by using correlation coefficients of the segmental duration. In terms of sociolinguistic factors, improving the 'comprehensibility' and 'accentedness' of Korean EFL learners' pronunciation is also important in international communication, which calls for more emphasis on suprasegmental features.

The purpose of this research is to study the aesthetic character of a mosaic which is expressed in the Modern Costume. The methods of the research were by literature and it was mainly done with reference to master's theses, doctor's theses, separate volumes, periodicals, domestic and overseas fashion magazines and internet on the subject. The result of the research appears as rhythm, exoticism, abstraction, mystery, recreation by disintegration. First, rhythm appears in a sense of free rhythm with the method of arranging motives and the kinds of materials varying. Second, exoticism gives impression with such motives as Oriental designs, African designs and the geometric designs of nature occupying the surface. Third, abstraction displays motives such as unrealistic fashion. Fourth, mystery gives a cyber-related impression with the help of such scientific materials as fluorescent plastics, metal and glass. Fifth, recreation pelves an aesthetic impression by reorganizing the costume with the disintegration and transformation of Industrial materials such as plastics, metal and glass, etc. based on their unique colors and quality.

This study aims to investigate the rhythmic patterns in the English speech produced by Chinese learners of English who learn English as a foreign language (EFL learners). Utilizing interval-based rhythm metrics, namely, VarcoC, VarcoV, nPVI-C, nPVI-V, and %V, the study compared the rhythmic differences in English speech between ten native speakers from the United States and forty Chinese EFL learners from mainland China. A sentence elicitation task consisting of thirty picture prompts and corresponding thirty stimuli sentences with at least five vocalic and four consonantal intervals was conducted. Statistical results reveal that both Chinese advanced learners and beginners had significantly lower degree of stress-timed in their English speech, indicating that the acquisition of the L2 speech rhythm was influenced by the learners' L1 rhythmic pattern. In addition, the results also show that the Chinese advanced learners had significantly higher degree of stress-timed in their English speech than beginners and showed no significant difference with native speakers in VarcoC and nPVI-C. These results indicate that the direction of L2 speech rhythm development was from more syllable-timed to more stress-timed.
