본 연구는 한류 지속가능성에 한류 드라마 '시청정도'가 미치는 직접효과와 '한류호감도' 및 '문화유입수용성'의 매개효과 그리고 '경쟁의식'의 조절효과를 실증적으로 규명하였다. 표본은 중국 광서성의 계림시와 하남성의 정주시에 거주하는 대학생(N=371명)이다. 분석 결과, 한국에 대한 '경쟁의식'이 상대적으로 약한 응답자들의 경우에는, '한류 지속가능성'에 유의한 영향을 미치지는 않았지만, 경쟁의식이 상대적으로 강한 응답자들은 한국 드라마 '시청정도'가 증가할수록, 오히려 한류 지속가능성에 대해서 회의적인 입장을 표명하여 주목하게 되었고, '경쟁의식'의 조절효과가 입증되었다. 한류 드라마를 많이 시청할수록, '한류 호감도'도 증가시키지만, '문화유입 수용성'에는 유의한 영향을 미치지 않았다. '시청정도'가 증가할수록, '한류지속 가능성'에 대한 부정적인 평가를 하는 경향은 '한류 호감도'가 증가할수록 유의하게 감소될 수 있어, '한류 호감도'의 매개효과가 입증되었다. 주요 발견점을 토대로 시사점과 함의를 논의하였다.

The purpose of the study is to analyze the impact of storytelling factor, technical factor and exhibition environment factor on the degree of satisfaction, degree of immersion and immersion types in and . Our findings show that the degree of satisfaction not only has a significant correlation with the degree of immersion, but also influences on the holding power and behavioral intention. According to the results of correlation analyses, three factors have an impact on the degree of satisfaction and immersion. Immersion factors influence negatively on Focused Attention and Heightened Enjoyment, however, the factors effect positively on Temporal Dissociation and Curiosity. As the influence of immersiveness on the degree of satisfaction and immersion, and immersion types have been verified, this study offers a fresh understanding of the importance of immersion factors as evaluation criteria for digital exhibitions.

This study aimed at exploring the effect of presoaking degree of lightweight aggregate (LWA) on the fresh and hardened properties of concrete. Two series (i.e., Series A and Series B) of concrete mixes that were made of LWA with different moisture states were prepared. The presoaking degree of LWA was divided into three types: oven dry state, 1 hour prewetted and 24 hours prewetted. For the Series A, the water content of the lightweight aggregate concrete (LWAC) mixes was adjusted in accordance with the moisture condition of the LWA. Whereas the amount of water added in the Series B mixes was deliberately not adjusted for the moisture condition of the LWA. Slump test, mechanical tests, interfacial transition zone microscopical tests and thermal conductivity test were carried out on the specimens of different concretes and compared with control normal-weight aggregate concretes. The test results showed that the effect of mixing water absorption by LWA with different moisture states was reflected in the fresh concrete as the loss of mixture workability, while in the hardened concrete as the increase of its strength. With the use of oven-dried LWA, the effect of reduction of water-cement ratio was more significant, and thus the microstructure of the ITZ was more compact.

Cyto-toxic effect of silver sulfadiazine (Ag-SD) on keratinocytes and its implication on wound healing process were investigated in $2^{nd}$ degree bum hairless mouse model. As a dermal model, HaCat (immortalized keratinocytes) monolayer culture in DMEM with 10% FBS was used. Cyto-toxicity of Ag-SD was estimated by measuring the cell viability using neutral red assay after adding the drug. The $2^{nd}$ degree bum was prepared on hairless mouse back skin (1 cm diameter) and dressings with Ag-SD were applied for 96 hr. The process of re-epithelialization and the presence of inflammatory cells were investigated and histology with Hematoxylin-Eosin staining was performed. Ag-SD displayed highly cyto-toxic effect on cultured HaCat cells in a concentration dependent manner $(1-100\;{\mu}g/mL)$. Topical application of Ag-SD (2%) could control the infection: no inflammatory cells were observed in histology. However the cyto-toxic effect of Ag-SD on skin cells induced the impairment in epidermal regeneration.

The purpose of this experimental study is to improve the workability and durability in high sulphated cement concrete with fly-ash. As a results, we can make high strength concrete by using only high sulphated cement but try to improve the workability and degree of strength by adding 10% fly-ash but the effect beyond my expectation to improve the workability and degree of strength does not show, and the improvable effect except the drying shrinkage of durability dose not show, either. So we must give attention to using fly-ash.

The purpose of this study was to analyze the effects of the degree of preparation for old age and the sense of crisis on the marital satisfaction of married mid-life women. The participants in this study were 300 women ranging in age from 40 to 59 years residing in Gyeonggi-do. Two hundred and forty-nine self-reported questionnaires were used for final analysis by SPSS PASW 18.0. The major results of this study were as follows. First, the mean score on the sense of crisis scale was $2.56{\pm}0.65$, representing a medium level. The mean scores for degree of preparation for later life and marital satisfaction were $3.54{\pm}0.57$ and $3.67{\pm}0.88$, which were somewhat high. Second, socio-demographic characteristics have a significant influence on married, middle-aged women. There were primarily differences in the sense of crisis by age cohort(such as women in their 50s) and level of education. Moreover, there were differences in the degree of preparation for later life by marriage duration and differences in marital satisfaction by level of education, monthly average income, and employment status. Third, in multiple regression analysis, the variables significantly influencing the marital satisfaction of married, middle-aged women included health status and monthly average income as control variables. Mid-life crisis also had a significant effect. The degree of preparation for emotional later life had a significant effect as an independent variable. These findings suggest that the level of sense of crisis and the degree of preparation for emotional later life affected the women's marital satisfaction. Other factors did not have a significant affect. Based on the above results, intervention alternatives are needed to improve the marital satisfaction of married, middle-aged women.

Purpose: This study determined the effect of inter dental brush education on the dental plaque index, and the degree of halitosis for elementary school students. Methods: The study was performed on a non-equivalent control group, with a pre-test and post-test design. The study was intended for a total of 50 students. They were divided into two groups; an experimental group of 25 students and a control group of 25 students. The experimental group participated in inter dental brush education. The education took about 20 minutes, and was provided once a week, for a total of three weeks. To quantify the effect, the two groups were compared in terms of the dental plaque index and the degree of halitosis. Results: Without inter dental brush education, or a test for homogeneity, in the sense of exact equivalence of the dental plaque index and the degree of halitosis between the experimental and the control group, was supported. (p>.799, p>.876). 1) The first hypothesis, "The experimental group, who participated in inter dental brush education, would reveal a lower dental plaque indices than the control group", was supported (t=5.78, p<.001). 2) The second hypothesis, "The experimental group, who participated in inter dental brush education, would reveal a lower degrees of halitosis than the control group", was supported (t=4.49, p<.001). Conclusion: The proposed inter dental brush education is effective in improving the dental plaque index and the degree of halitosis for elementary school students.
