Although culture becomes a high value-added industry and interest in pure art is increasing, government, business, and private organizations are increasing support for the culture and arts industry, the traditional performances are mostly free. Therefore this study suggested measures to improve supports for traditional art organizations as well as effective strategies allowing private traditional art organizations to strengthen its self sustain and its competitiveness by analyzing the Cultural Policy of Germany. First, a policy approach to traditional performing arts is needed at the local level. There is a difference between Korea, which is the central government system, and Germany, which is a federation, in terms of national operating system. However, their cultural federation has developed the traditional culture and traditional arts of each region. Therefore, it is necessary to establish public policy that can preserve and support traditional culture in the provinces. Second, the development of cultural contents which enables audience to meet their desire for enjoying performances and allows the Korean ethnic identity to be established is necessary. In the 21st century, there is a global trend that not only does the culture industry significantly influence the success and the failure of economic policies in each country but also the culture industry is boosted as the strategic industry.

Purpose: The purpose of this study was to measure the influence of job stress, critical thinking disposition, and clinical decision-making ability on clinical nurses’ medication safety competence. Methods: A descriptive survey was conducted among 140 nurses with more than 6 months of work experience in 4 general hospitals in Busan metropolitan city. Data were collected from August 15 to October 30, 2021 and analyzed using the independent t-test, one-way ANOVA, Pearson’s correlation coefficients, and stepwise multiple regression. Results: Medication safety competence had significant correlations with job stress (r=.20, p=.021), critical thinking disposition (r=.63, p<.001), and clinical decision-making ability (r=.54, p<.001). Multiple regression analysis for medication safety competence revealed that the most powerful predictor was critical thinking disposition. Job stress and critical thinking disposition explained approximately 45% of the variance in medication safety competence. Conclusion: This study confirms the need to make systematic efforts in clinical settings to improve nurses’ medication safety competence, and seeks ways to do so. To enhance clinical nurses’ medication safety competence in the future, programs that manage job stress and improve critical thinking disposition within the nursing department in particular and the hospital in general should be developed and implemented.

김가현(Kim Ga Hyun),문영식(Moon Young Shik) 한국정보처리학회 1999 정보처리학회논문지 Vol.6 No.4

In this paper, an efficient automatic video parsing technique on MPEG-compressed video that is fundamental for content-based indexing is described. The proposed method detects scene changes, regardless of IPB picture composition. To detect abrupt changes, the difference measure based on the dc coefficient in I picutre and the macroblock reference feature in P and B pictures are utilized. For gradual scene changes, we use the macroblock reference information in P and B pictures. The process of scene change detection can be efficiently handled by extracting necessary data without full decoding of MPEG sequence. The performance of the proposed algorithm is analyzed based on precision and recall. The experimental results verified the effectiveness of the method for detecting scene changes of various MPEG sequences.

We analysed 504 women in their 20s in order to find out an association between personal color types and images by face shape. The findings of this study showed that images by face shape may work as one of variables in personal color diagnosis. First, ‘spring’ personal color saw round- or egg-shaped face be the most frequent in its distribution. This means ‘cheerful’, ‘youthful’, ‘young-looking’, ‘pretty’ images a round-shaped face invokes and ‘innocent’ image an oval face creates may be a meaningful standard in diagnosing ‘spring’ personal color. Second, among those the most frequently distributed in ‘summer’ personal color were a round-shaped face, an oval face, an inverted triangle-shaped face and a diamond- shaped face. This show ‘friendly’, and ‘gentil’ images of a round-shape face and ‘soft’, ‘natural’, ‘friendly’, ‘warm’ or ‘gentle’ images of an oval face may be a meaningful criterion in ‘summer’ personal color diagnosis; and a ‘trustworthy’ or ‘faithful’ images of square-shaped face and ‘intellectual’ image of an inverted triangle-shaped face may be also a significant standard in ‘summer’ personal color diagnosis. Third, a diamond-shaped face and a long- shaped face were the most often distributed in ‘autumn’ personal color. This shows ‘mature’ image of a diamond-shaped face and ‘mature’, ‘composed’, ‘adult’, calm’, ‘intellectual’, ‘classic’, ‘feminine’ or ‘lofty’ images of a long-shaped face may be a meaningful measurement in ‘autumn’ personal color diagnosis. Fourth, ‘winter’ personal color saw square-shaped face, a diamond-shaped face and an inverted triangle-shaped face the most frequently distributed in it. This means ‘confident’ or ‘active’ images of a square-shaped face, ‘cool’ image of a diamond-shaped face and ‘cool’ or ‘sharp’ images of an inverted triangle-shaped face may be a meaningful criterion in diagnosing ‘winter’ personal color. In conclusion, an important implication is that images of face shape might be a new standard in personal color diagnosis, further stimulating a variety of beauty service based on face perception consumers can enjoy by using smart phone or smart mirror.

The purpose of this study is to examine the features of fusion historical dramas aired after 2000 and the changes of the characters`` costumes, by means of comparing and analyzing the costumes worn in the dramas covering one identical character, Jang Okjeong., one of King Sukjong’s concubines, well known as a femme fatale in the Korean history, and one of the most frequently reinterpreted characters among historical dramas aired in Korea: in two films and seven dramas. Among them, three works released after 2000, KBS Jangheebin(2002), MBC Dongyi(2010), and SBS Jang Okjeong, living in love(2013), were chosen for this study. In order to find out the features and differences, the three dramas were viewed and captured, and then the captured scenes were analyzed. The results of this study are as follows. Above all, costumes of fusion historical dramas after 2010 were much different from those in the early 2000s. Also, as the character Jang Okjeong undergoes diverse changes in social status, and in her characteristic and situation as well, Dongyi and Jang Okjeong, living in love reveal a tendency to show these changes through the designs of their costumes. The term of “fusion” shows an attempt for diversify and modernization of traditional costumes of historical dramas. Controversies in the historical research would be inevitable, but they have great significances in that they add modern aesthetics of viewers to the historical works, at the same time, in that they help viewers understand the traits of the characters and their situations through their costumes.
