Purpose: The purpose was to examine the effectiveness of a psychosocial stress management program on stress and coping in student nurses. Method: A nonequivalent control group pre-posttest design was used. A convenience sample of 24 students from the Department of Nursing, Wonju College of Medicine, Yonsei University were assigned to experimental (n=12) and control groups(n=12). Stress was measured using the Visual Analog Scale (10 points) and blood cortisol. Coping was measured using a scale modified by So (1995) based on the Ways of Coping Checklist developed by Folkman and Lazarus (1985). Depression was measured using the CES-D by Radloff (1977) and state anxiety, using the State Anxiety Inventory by Spielberger (1976). The psychosocial stress management program included education, relaxation (Korean Dan Jeon-typed Breathing and music), and social support. Result: Results showed for the two groups, 1) a significant difference in stress scores (U= 19.50, p=0.002), 2) no difference in cortisol levels (8am, 4pm), 3) a significant difference in problem-focused coping (U=25.50, =0.007), 4) no difference in emotion-focused coping, and 5) no difference in state anxiety and depression. Conclusion: By utilizing the program, students were able to learn how to control their stress and improve their coping. Therefore with a partial modification, psychosocial stress management can be useful for continual management of stress in student nurses.

Purpose: This study was conducted to develop and evaluate a dementia prevention intervention program for the elderly with mild cognitive disorder. Methods: The study was nonequivalent control group pretest-posttest design. The subjects of the study were a total of 68 elderly who ranged from 21 to 24 of total scores of K-MMSE, aged over 65, in home. The program consisted of music therapy, humor therapy, art therapy, dancing therapy, recreation, and health education to enhance brain function. The program was applied to the experimental group twice a week, ninety minutes per session for eight weeks. The data were analysed by using chi-square test and t-test. Results: The variables measured in the experimental group and the control group before the intervention were not significantly different in the homogeneity test. The dementia prevention program improved the cognition(t=9.243, p<.001), self-esteem(t=.4.336, p<.001), quality of life(t=8.375, p<.001) and reduced depression(t=-3.913, p<.001). Conclusion: These findings confirmed that the dementia prevention program made a contribution to improving cognitive function, self-esteem, and quality of life and also to reduce depression in the elderly with mild cognition disorder. Therefore, it is recommended that this program could be used in clinical practice as an effective nursing intervention for the elderly with mild cognitive disorder.

There is a dazzling display of colors used in contemporary visual media. The flood of color image in films leads to the application of partial colors onto the monotonous image, which is one of the reverse phenomena in this field of visual media. Nowadays, it became possible to revise the colors of moving images through computer graphics, and the excessive use of colors has a tendency to make visual impact uninteresting. The attempt is applied in a variety of ways from making video commercials and music videos as well as films. In particular, the application of partial color in the monotonous image in films such as Schindler's List(1993) and Sin City(2005) gave scores of audiences a fresh shock and added the depth of moving image. The purpose of this study is to examine how the principles and properties of the color affect us and how the application of monotone shows its effectiveness in moving images. By analyzing various case studies, this paper will propose and validate the progressive value toward the application of moving images in combination in the future.

It is essential to improve the quality of life of the elderly in aging society. Regular exercise as nursing intervention is needed to prevent diseases, maintain and promote their health, and thus promote the quality of life for the elderly, especially who generally had poor cognition for their health maintenance and promotion in a low class community. Subjects consisted of 30 women. over 65 years old in a community welfare center, who lived in the low class apartments financially supported by the local government in G city, Gangwon Province, Korea. The program consisted of dancing on music for approximately 50 minutes, 3 times a week for 10 weeks. Experimental data were analyzed with $x^2-test$, t-test, mean values, standard deviation, percentage of change and paired t-test using SAS program. After the recreation dance, the mean value of the experimental group was decreased from 7.62 to 7.44 (t=-0.258, P=0.799), and that of the control group was also decreased from 7.00 to 6.58 (t=-0.971, P=0.349) in depression. However, there were no statistically significant differences in scores of depression between two groups. In life satisfaction, the mean value of the experimental group was increased from 19.07 to 26.50 (t=2.392, P=0.030), but that of the control group was decreased from 15.92 to 13.71 (t=-1.060, P=0.305). Thus it shows that there was a statistically significant improvement on life satisfaction after the recreation dance.

This study was performed to explore the effects of a dance therapy on physical and psychological characteristics in the elderly. The design of this study was a non-equivalent pre-post test experiment. The subjects consisted of elderly persons living in a facility located in Suweon and Bucheon. Fifty eight subjects, aged between 65 and 93 years who had normal cognition, sensory function, balance, and resting blood pressure. They underwent tests of balance, flexibility, muscle strength, depression, and anxiety as baseline data before dance therapy, and at 6th week and at the end of the 12nd week after following dance therapy. Twenty seven elderly persons were assigned to the experimental group and participated with the dance therapy between April and July, 1998. The dance therapy was developed by the author with the help of a dance therapist and a physiatrist. This therapy was based on the Marian Chace's dance therapy and Korean traditional dance with music. The dance therapy consists of 50 minutes session, 3 times a week for 12 weeks. One session was consisted of warming-up, expression, catharsis, sharing, and closing stage. The intensity of the dance therapy was at the 40 % of age-adjusted maximum heart rates. Data were analysed with mead standard deviation, Chi-square test, unpaired t-test, repeated measures ANOVA, and Bonferroni multiple regression using SAS program. 1. The results related to the physical characteristics were as follows : 1) The balance (standing on one leg, walking on the balancing bar), flexibility and muscle strength (knee extensor, knee flexor, ankle plantarflexor and dorsiflexor) of the experimental subjects significantly increased over time mere than that of the control subjects. 2) The experimental group had significantly higher score for balance, flexibility, muscle strength of knee extensor, and knee flexor than the control group at the 12nd week after dance therapy. 3) The experimental group had significantly higher score for muscle strength of ankle dorsiflexor and plantarflexor than the control group at the 6th week and the 12nd week after dance therapy. 2. The results related to psychological characteristics were as follows : 1) Scores of Geriatric Depression Scale, Hamilton Depression Rating Scale, and Zung's Self-rating Anxiety Scale of the experimental group were significantly decreased over time more than that of the control group. 2) The experimental group had significantly lower score for depression than the control group at the 12nd week after dance therapy. 3) The experimental group had significantly lower score for anxiety than the control group at the 6th week and the 12nd week after dance therapy. The findings showed that the dance therapy could be effective in improving the balances, flexibility, and muscle strength of lower limb, and effective in decreasing the depression and anxiety of the elderly. Additional merits of the dance therapy would be inexpensiveness, easy accessibility, and increasing interpersonal relationship. It can be suggested that the dance therapy is effective in the health promotion of the elderly.

The Purpose of this study was to find the way of discriminating EEG for some mental activity. which are not characterized within linear spectral analysis but with non-linear analysis . We lave investigated the way of characterizing EEG changes during emotional and cognitive states in healthy volunteered subjects who responded to three designed status. in which the subjects were relaxing with ease and eyes closed. listening to music and computing a simple subtraction with eyes closed. Especially, we estimated EEG dimensional complexity by Skinner s Point-wise correlation dimension(PD2) method for each mental states. As a result it has been found that the subjects, who responded that the\ulcorner had concentrated well during the arithmetic task. show higher PD2 in their non-linear EEG measures. in comparison with the subjects who responded that they had not concentrated during the task This highness of PD2 is also significant in statistical analysis. A subject who had the highest score in evaluating the intensity of induced emotion during emotional task shows significantly lower PD2 in statistical analysis than other subjects who had lower scores. Linear spectral analysis was also performed on these data. However, they did not show and significant difference. Only non-linear dynamical analysis shows the significant different result on these mental status.

The Cheondeok-Song (religious songs of Cheondo-Gyo) of the Japanese colonial period shown on Cheondo-Gyohwe-Weolbo, the monthly magazine of Cheondo-Gyo Church were examined in this paper. The results are as follows. There are scores of songs, lyrics, and articles related to Cheondeok-Song in the monthly magazine. The five-tone scale or Korean traditional rhythm style was partly used, but western music form was dominant in most of the songs. Especially the four-part form of Christian hymns became usual since 1931. This shows how people thought of the new trends. The reception of the new trends being emphasized, but they recognized tradition as an object of overcoming rather than of succeeding. The lyrics contain religious contents and the spirit of the period to restore national self-respect and contribute to the world peace through overcoming Japanese imperialism. But the rhythm of seven and five syllables which is suspected to have been introduced by Japan was spread after the 1920s. Cheondeok-Song have been sung in the three grand anniversaries and other anniversaries, the Prayer-day, in Cheondo-Gyo church services on Sunday, ceremonies, and in lecture. There are various kinds of songs and their status is very high. Especially, Cheondeok-Song have been used actively in mission works and edification for women. Cheondeok-Song actively reflected the domestic and international trends and the demands of that times. They could sing self perfection through enlightenment and also the social reform based on it. These are the reasons why I think Cheondeok-Song of those days are so important. Cheondeok-Song reflected modern elements actively, but couldn't succeed the national form and the traditional elements properly. The problem of cultural identity is not only a specific group's but also that of the whole humanity of maintaining cultural diversity. This is also a task that Cheondo-Gyo Cheondeok-Song have to solve in the future.

Nagyangchun is a Dangak that has been handed down to the present time with Boheoja as a Saak of the Song Dynasty which was introduced in the Goryeo Dynasty. The title and lyrics of Nagyangchun are conveyed in the Dangakjo of Goryeosa-akji and the Jeungbomunheonbigo. The remaining scores containing Nagyangchun include Akjangyoram, Sogagwonbo Vol.4 and Vol.6 of the Joseon Dynasty and Aakbu-akbo, the 6th Aaksaeng-gyogwacheol, Leewangjikaakbu-oseonakbo during the Japanese colonial period. Besides, the current melody of Nagyangchun is based on Hangugeumak and Gugakjeonjib published by the National Gugak Center. This paper aims to examine how Nagyangchun, which is currently being performed at the National Gugak Center, went through the process of change to have the same structure and form as it is now using these scores as a research subject. The study results are summarized as follows. First, the song of Nagyangchun, which was originally Saak but transmitted as an instrumental piece without lyrics, first appeared in the Hangugeumak Vol.16 and Gugakjeonjib Vol.7 published by the National Gugak Center in 1978 and 1979. In this process, the Janggu added by Kim Ki-soo is now disappearing and is replaced by Jwago. Second, though the five notes of 黃, 太, 仲, 林, and 南 have been maintained unchanged since the Akjangyoram, the pitch of 無/應 and 夾/姑, which appear once each, gradually rises and is unified into 應 and 姑 during the period of Aaksaeng-gyogwacheol or at the latest Leewangjikaakbu-oseonakbo, and reached the present. Third, the current melody of Nagyangchun consists of a structure in which the tones and range of each phrase rises within the form of Mijeonsa (a·b·c·d) and Mihusa (e·b'·c'·d'). Particularly, except for the a-type and e-type melodies, which are the introduction for the Mijeonsa and Mihusa, the remaining melodic types show a gradually descending structure within the corresponding phrase, so the structure of ascending and descending is generally in harmony. Forth, the Ganeum that appeared from Aakbu-akbo are currently classified into seven types, and they appear in ascending pitches of 2nd, 3rd, 4th, and 5th and play a role in smoothly or fluently connecting melodic progression. Fifth, after Akjangyoram, Nagyangchun, which had been handed down as an instrumental piece without lyrics, was restored in 1960 by Lee Hye-gu, and is being passed down as the form of male and female vocals added to the instrumental accompaniment. As a result of examining the current Nagyangchun, which was formed through the process of change after Akjangyoram, it was found that there were tasks that required reconsideration of the current Nagyangchun, which is being played at the National Gugak Center, such as the arrangement of Janggu, the identification of the key, and the investigation of the lyrics. When follow-up studies are continued in the future, it will be able to contribute to the cultural transmission of Nagyangchun.

Dasiraegi is a traditional funeral rite performance of Jindo located in the South Jeolla Province of South Korea. With its unique stylistic structure including various dances, songs and witty dialogues, and a storyline depicting the birth of a new life in the wake of death, embodying the Buddhism belief that life and death is interconnected; it attracted great interest from performance organizers and performers who were desperately seeking new contents that can be put on stage as a performance. It is needless to say previous research on Dasiraegi had been most valuable in its recreation as it analyzed the performance from a wide range of perspectives. Despite its contributions, the previous researches were mainly academic focusing on: the symbolic meanings of the performance, basic introduction to the components of the performance such as script, lyrics, witty dialogue, appearance (costume and make-up), stage properties, rhythm, dance and etc., lacking accurate representation of the most crucial element of the performance which is sori (song). For this reason, the study analyzes the music of Dasiraegi and presents its musical characteristics along with its scores to provide practical support for performers who are active in the field. Out of all the numbers in Dasiraegi, this study analyzed all of Geosa-nori and Sadang-nori, the funeral dirge (mourning chant) sung as the performers come on stage and Gasangjae-nori, because among the five proceedings of the funeral rite they were the most commonly performed. There are a plethora of performance recordings to choose from, however, this study chose Jindo Dasiraegi, an album released by E&E Media. The album offers high quality recordings of performances, but more importantly, it is easy to obtain and utilize for performers who want to learn the Dasiraegi based on the script provided in this study. The musical analysis discovered a number of interesting findings. Firstly, most of the songs in Dasiraegi use a typical Yukjabaegi-tori which applies the Mi scale frequently containing cut-off (breaking) sounds. Although, Southern Kyoung-tori which applies the Sol scale was used, it was only in limited parts and was musically incomplete. Secondly, there was no musical affinity between Ssitgim-gut and Dasiraegi albeit both are for funeral rites. The fundamental difference in character and function of Ssitgim-gut and Dasiraegi may be the reason behind this lack of affinity, as Ssitgim-gut is sung to guide the deceased to heaven by comforting him/her, whereas, Dasiaregi is sung to reinvigorate the lives of the living. Lastly, traces of musical grammar found in Pansori are present in the earlier part of Dasiraegi. This may be attributed to the master artist (Designee of Important Intangible Cultural Heritage), who was instrumental in the restoration and hand-down of Dasiaregi, and his experience in a Changgeuk company. The performer's experience with Changgeuk may have induced the alterations in Dasiraegi, causing it to deviate from its original form. On the other hand, it expanded the performative bais by enhancing the performance aspect of Dasiraegi allowing it to be utilized as contents for Performing Arts. It would be meaningful to see this study utilized to benefit future performance artists, taking Dasiraegi as their inspiration, which overcomes the loss of death and invigorates the vibrancy of life.

Collaborative filtering (CF) algorithm has been popularly used for implementing recommender systems. Until now, there have been many prior studies to improve the accuracy of CF. Among them, some recent studies adopt 'hybrid recommendation approach', which enhances the performance of conventional CF by using additional information. In this research, we propose a new hybrid recommender system which fuses CF and the results from the social network analysis on trust and distrust relationship networks among users to enhance prediction accuracy. The proposed algorithm of our study is based on memory-based CF. But, when calculating the similarity between users in CF, our proposed algorithm considers not only the correlation of the users' numeric rating patterns, but also the users' in-degree centrality values derived from trust and distrust relationship networks. In specific, it is designed to amplify the similarity between a target user and his or her neighbor when the neighbor has higher in-degree centrality in the trust relationship network. Also, it attenuates the similarity between a target user and his or her neighbor when the neighbor has higher in-degree centrality in the distrust relationship network. Our proposed algorithm considers four (4) types of user relationships - direct trust, indirect trust, direct distrust, and indirect distrust - in total. And, it uses four adjusting coefficients, which adjusts the level of amplification / attenuation for in-degree centrality values derived from direct / indirect trust and distrust relationship networks. To determine optimal adjusting coefficients, genetic algorithms (GA) has been adopted. Under this background, we named our proposed algorithm as SNACF-GA (Social Network Analysis - based CF using GA). To validate the performance of the SNACF-GA, we used a real-world data set which is called 'Extended Epinions dataset' provided by 'trustlet.org'. It is the data set contains user responses (rating scores and reviews) after purchasing specific items (e.g. car, movie, music, book) as well as trust / distrust relationship information indicating whom to trust or distrust between users. The experimental system was basically developed using Microsoft Visual Basic for Applications (VBA), but we also used UCINET 6 for calculating the in-degree centrality of trust / distrust relationship networks. In addition, we used Palisade Software's Evolver, which is a commercial software implements genetic algorithm. To examine the effectiveness of our proposed system more precisely, we adopted two comparison models. The first comparison model is conventional CF. It only uses users' explicit numeric ratings when calculating the similarities between users. That is, it does not consider trust / distrust relationship between users at all. The second comparison model is SNACF (Social Network Analysis - based CF). SNACF differs from the proposed algorithm SNACF-GA in that it considers only direct trust / distrust relationships. It also does not use GA optimization. The performances of the proposed algorithm and comparison models were evaluated by using average MAE (mean absolute error). Experimental result showed that the optimal adjusting coefficients for direct trust, indirect trust, direct distrust, indirect distrust were 0, 1.4287, 1.5, 0.4615 each. This implies that distrust relationships between users are more important than trust ones in recommender systems. From the perspective of recommendation accuracy, SNACF-GA (Avg. MAE = 0.111943), the proposed algorithm which reflects both direct and indirect trust / distrust relationships information, was found to greatly outperform a conventional CF (Avg. MAE = 0.112638). Also, the algorithm showed better recommendation accuracy than the SNACF (Avg. MAE = 0.112209). To confirm whether these differences are statistically significant or not, we applied paired samples t-test. The results from the paired samples t-test presented that the difference between SNACF-GA and conventional CF was statistical significant at the 1% significance level, and the difference between SNACF-GA and SNACF was statistical significant at the 5%. Our study found that the trust/distrust relationship can be important information for improving performance of recommendation algorithms. Especially, distrust relationship information was found to have a greater impact on the performance improvement of CF. This implies that we need to have more attention on distrust (negative) relationships rather than trust (positive) ones when tracking and managing social relationships between users.
