문화예술 영역별 소비향유가 문화적 자기효능감 및 지식에 미치는 영향과 그 성별 차이에 관한 연구
변상호 한국문화관광연구원 2018 문화정책논총 Vol.32 No.3
This study compared effects of five culture & art domains on cultural self-efficacy and knowledge. The domains are literature & books, plastic art, film & drama, classical performing art and popular performing art. Gender difference was examined in each domain. A nationwide online survey(N = 547) was conducted with a stratified sampling. The study found that the effects on cultural self-efficacy and knowledge are different between domains. Classical performing art is most highly effective, but film & drama has a negative effect. Gender is moderating the main effects. Plastic art and popular performing art have positive effects on cultural self-efficacy among women. An Effect of literature & books on knowledge is positive among men. Theoretical and practical implications were discussed. 최종 <국문초록> 본 연구는 인문학 분야 등의 도서·출판, 미술·조형예술, 영화·드라마, 순수·클래식공연, 대중공연 등 문화예술 5개 영역별 소비향유가 문화적 자기효능감과 지식에 미치는 영향이 다른지를 분석하였다. 각 영역에 있어 그 영향이 성별에 따라 달라지는지도 살펴보았다. 성별·연령별 비례할당방식에 근거한 전국단위 표본을 수집하여 이메일 설문조사(N = 547명)를 실시하였다. 연구결과, 첫째 문화예술 5개 영역별 개인의 소비향유는 서로 정(+)적 상관관계를 맺고 있었다. 문화예술에 대한 소비향유(빈도)는 영화·드라마 영역을 제외하고 여성이 남성보다 더 큰 것으로 나타났다. 둘째, 문화예술 5개 영역별 소비향유의 효과는 차이가 있었다. 인문학 분야 등의 도서·출판, 미술·조형예술, 순수·클래식공연 등의 소비향유는 문화적 자기효능감과 지식에 정(+)적 영향을 주었다. 대중공연은 지식에 정(+)적 영향을 미쳤다. 영화·드라마는 지식에 부(-)적 영향을 끼쳤다. 셋째, 문화예술 5개 영역에서의 소비향유가 문화적 자기효능감과 지식에 미치는 영향에 있어 성별에 따른 차이가 있었다. 미술·조형예술과 대중공연은 여성의 문화적 자기효능감에 정(+)적 영향을, 영화·드라마는 여성의 문화적 자기효능감에 부(-)적 영향을 미쳤다. 인문학 분야 등의 도서·출판은 남성의 지식에 정(+)적 영향을 주었다. 끝으로 이론적·현실적 함의를 논의하였다.

The effects of Quenching and Partitioning (Q&P) and Annealed Martensite (AM) heat treatment on the microstructure and tensile properties were investigated for 0.24C-0.5Si-1.5Mn-1Al steels. The Q&P steels were annealed at a single phase ($\gamma$) or a dual phase (${\gamma}+{\alpha}$), followed by quenching to a temperature between $M_s$ and $M_f$. Then, enriching carbon was conducted to stabilize the austenite through the partitioning, followed by water quenching. The AM steels were intercritically annealed at a dual phase (${\gamma}+{\alpha}$) temperature and austempered at $M_s$ and $M_s{\pm}50^{\circ}C$, followed by cooling in oil quenching. The dual phase Q&P steels showed lower tensile strength and yieldyield strength than those of the single phase Q&P steels, and tThe elongation for the dual phase Q&P steel was partitioning 100s higher than that of that for the single phase Q&P steels as the partitioning time was less than 100s up to partitioning 100s. For AM steels, the tensile/yield strength decreased and the total elongation increased as the austempering temperature increased. The stability of the retained austenite controlled the elongation for Q&P steels and the volume fraction of the retained austenite controlled the elongation for AM steels.

In this study, it is analyzed comparing the difference between the major metropolitans in the world, which based on the assumption by increasing the number of fire officials will reduce the number of fires in the result of fire prevention activities as fire inspections. Also over the past 25 years, “if urban expansion and population has been increased in the metropolitans, it must be increased the number of fires in Korea and foreign cities”, as expected. Found in this analysis, even though the population had increased, the number of fires in the metropolitans of the world had not increased or rather decreased. But the premise with the hypothesis differently in spite of the cities' population have increased, it was founded that the number of fires have decreased despite reduced the number of fire officers in foreign cities. However, considering to increase the number of fire officers in order to reduce the fires, achieving the reduction of fires, based on scientific research and systematic safety management, will be cost-effective fire-reduction policies.

Application areas of floating marine structure systems have been increased with the development of power generation systems using renewable energy. Hence it is necessary to analyze the behavior of these floating systems for efficient design and operation. In this study, a computational analysis was performed to predict the characteristics of mooring lines load variation connected to a floating marine structure with waves. Pressure on the floating body and mooring lines load were analyzed with wave direction and height. The floating body stability severely decreased for 90° of the wave incident direction, and maximum load of the mooring lines increased with the height. These results are expected to be applicable for optimal design of the marine floating system.

This study critically examined the rationale of NoelleᐨNeumann’s ‘spiral of silence’, which was based on presumption of others’ perception and majority influence in climate of opinion. This study explored the possibility of minority influence from the perspective of powerᐨrelations and investigated whether an individual’s selfᐨ censorship on expression of opinion, chilling effect, in SNS is produced by perceived effect of a power agent’s surveillance on self rather than presumed effect on others. A nationwide online survey(N = 455) with a stratified sampling found that presumed others’ censorship had no influence on self’s censorship but self’s censorship had a significant influence on presumed others’ censorship. Results of the study suggest that an individual is likely to censor his or her own expression of opinion due to the fear of a power agent rather than presumed majority in climate of opinion.
