최근 경주, 포항에 연이은 지진 발생으로 인하여 내진설계에 관심이 높아지고 있다. 다가구주택 필로티기둥은 수직 비정형 시스템으로 상,하부층의 강성 차이로 인하여 지진 발생 시 막대한 피해가 예상되기 때문에 다가구주택 필로티기둥의 내 진보강이 필요하다. 그러나 민간 소유인 다가구주택의 경우 막대한 비용과 시간으로 인하여 보강이 어려운 실정이다. 이에 따 라, 복합섬유패널로 에폭시 접착제 미사용으로 건식시공이 가능한 전단보강공법을 제안하고자 한다. 본 연구에서는 복합섬유패 널 보강 유무에 따른 내진보강공법의 전단내력을 실험을 통하여 검증하였고, 에폭시를 사용하지 않아 일체화 거동을 하지는 않 지만 복합섬유패널의 영향으로 전단내력은 1.46∼1.49배 증가하는 것으로 평가되었다. 따라서 다가구주택 필로티기둥의 내진보 강효과가 있을 것으로 판단된다.
2000년대 이후, 우리나라에서는 공립미술관이 대거 개관하면서 그 중요성을 새롭게 재인 식하는 시대를 맞이하였다. 이와 함께 공립작가미술관도 계속 증가해가며 그 입지를 더욱 강화해 가는 모습을 보여주고 있다. 요제프 슘페터는 새로운 것들의 끊임없는 결합과 적용을 통해 기존 의 것들을 혁신해나가는 ‘창조적 파괴’의 개념을 고안해냈다. 따라서 이 연구는 ‘이응노의집’에 초점을 맞춰 우리나라 공립작가미술관의 현황을 점검해보고, 창조적 파괴의 개념을 통해 이응노 의 예술세계를 기념하는 이응노의집의 미래경영 방안을 제언해 보고자 한다. 특히 이 연구는 근 대미술관이 부재한 한국의 미술관 현황을 고려하여 이응노의 예술세계를 핵으로 하는 근대미술 관으로 자리매김하는 이응노의집의 미래경영 전략과 방안을 구상해 보여주고자 한다.
In order to improve the implementation of safety and health education at the site for industrial accident prevention activities, research was conducted to minimize inconvenience and increase utilization by redesigning and developing existing education methods. To date, occupational safety and health education has been conducted without considering the general work characteristics and functional facilities (mechanical, electrical, instrumentation, chemical) of workers (mechanical: turbine, valve, pump, hydraulic system, electrical: generator, breaker, motor, etc.). In particular, plant facilities were classified as mechanical and electrical facilities to improve the methodology for industrial safety and health education for plant maintenance workers. In addition, the “One Page Education Plan” was announced as a learning case because the spread of COVID-19 infectious diseases made it impossible to reduce or control the number of people in all groups and groups. The improvement of this training method will play a major role in improving the effectiveness of safety education in power plant workplaces.
본 논문에서는 반도체 특성의 단일벽 탄소나노튜브(semi-SWNTs)와 페로브스카이트(perovskite) 양자 점을 혼합하여 SWNT의 높은 전하 이동 특성과 양자점의 고효율 광전 특성을 동시에 가지는 용액공정 가 능한 기반 고성능 광센서를 개발하기 위한 연구를 수행하였다. 직경이 작은 SWNT를 공액 구조 고분자 반도체를 이용해 선택적으로 분리/분산하는 방법으로 제조하여 포토트랜지스터의 반도체 채널 층으로 활 용하고, 가시광 빛에 높은 흡광도를 가지는 양자점을 다양한 조성과 구조를 가지는 광활성층으로 제조하 여 그 특성을 비교 분석하였다. 이 결과 semi-SWNTs와 페로브스카이트 양자점 모두 단독으로 TFT에 사 용하였을 경우 우수한 트랜지스터 특성과는 별개로 광전효과가 크게 나타나지 않았으며, 두 종류 이상의 반도체 소재를 융합하여 사용할 경우 양자점에 흡수된 빛에 의해 엑시톤이 형성되고 이종 접합 계면에서 전자와 정공의 분리가 쉽게 이루어지도록 유도함으로써 낮은 광량에서도 높은 효율을 가지는 포토트랜지 스터를 개발할 수 있었다. 향후 지속적인 연구개발을 통해 고유연/저가 광 센서 제품 개발과 레이더, 이미 지 센서, 웨어러블 헬스케어 등의 다양한 분야에 하이브리드 반도체 포토트랜지스터가 응용될 수 있을 것 으로 기대한다.
The aim of this study was to develop Jiangxi Nuo masks using 3D digital fashion design technology and suggest various ways to utilize traditional culture based on the characteristics of Nuo masks, a traditional Chinese artifact of intangible cultural significance. The researchers conducted a literature review to gather information about Nuo culture and masks that could represent Jiangxi. Features of the masks were analyzed and classified. The result are as follows. First, the symbolic characteristics of Jiangxi’s Nuo masks can be divided into those based on their origin and history, the user’s social status, and the notions of primitive beliefs of the chosen people, such as naturism and totemism. Second, Nuo masks’ splendid decorations convey meanings such as luck, the bixie, longevity, wealth, and peace in the family. Third, playfulness in mask-making is about dismantling the original form of the mask, re-creating it through application. Fourth, the masks express primitiveness mostly by conserving the wood’s original color or material. The initial masks carved to represent images of figures aptly deliver the primitive forms and images of Nuo culture. In this study, Nuo masks were developed and produced using the 3D digital technology CLO 3D by adopting the expressive characteristics and applying design methods such as asymmetricity, exaggeration, and modification. The results of this study demonstrate the possibility of creating diverse as well as economical designs through the reduction of production.
The purpose of this study is to investigate historical and geographical environments in the development of the Naxi costumes of Chinese ethnic minorities and their characteristics—including religious cultures and totem worship—and to suggest the direction of fashion design toward the modernization of traditional costumes. The research methodology involved the collection of materials and investigatation into the history, culture, and characteristics of Naxi costumes; in particular, the “seven-star” sheepskin cape, one of the Naxi people’s important ethnic costumes as demonstrated by the women’s clothing that has been designed in reflection of this traditional costume. The results are as follows. First, Naxi costumes are found to have overall coherence and distinct locality when retained in the process of modernizing the traditional costume. The theme of this work is titled “By the Light of the Moon and the Stars,” which is expressed in contemporary fashion by the use of grey and dark red against a background of black, a color preferred by the Naxi people. Second, the Naxi people’s seven-star sheepskin cape is a symbol of women’s clothing with its characteristic patterns, shapes, and colors, and it is subject to creative modernization while retaining its unique ethnic characteristics. Third, the work expresses the contemporary stylishness of the costume while maintaining the customary decorative accessories from the Naxi people’s traditional culture.
This study analyzed the relationship between efficient pitchers and teams advancing to the postseason in Korean professional baseball through DEA. A total of 1,133 pitchers who threw more than one inning from the 2014 season to the 2018 season were selected for this study. For DEA analysis, input variables were selected as annual salary and inning output variables as Wins, Saves, and Holds and the number of efficient pitchers for each season was classified using the input-oriented BCC model. After that, it was divided into two groups based on joining the postseason or not, and the number of efficient pitchers was compared through a prop test. As a result of the analysis, the groups that advanced to the postseason in the rest of the season except for the 2014 and 2017 seasons had more efficient pitchers. Considering that the 2014 season recorded the highest WAR (Wins Above Replacement) at 183.56 compared to other seasons, most pitchers threw well, and in the 2017 season, they made more mistakes in pitching than in other seasons, but they performed well in batters. The results of this study have expanded the research field using efficiency analysis in professional baseball and can be used as useful data for practical research.
