이예린의 작품은 군더더기 없이 단순명료한 인터페이스를 가지고 있지만, 내포적 다양성이 풍부하다. 대표적인 사진 작품들은 그림자이긴 하지만, 물에 비친 그림자이기에 거울 같은 반영상이다. 거기에는 재현의 기원이 되는 그림자와 거울의 모델이 동시에 작동한다. 배수가 잘 안되어 하수구로 빠져나가지 못한 물이 고여 생긴 이 순간의 연못은 다른 세상을 담는 틀이 되었다. 현실과의 최소한의 접점을 가지는 상상세계는 회화에서 극대화되고, 드로잉에서는 추상적 요소들로 분해되어 있지만, 사진 작업에서는 절묘한 균형을 이룬다. 현실과 상상은 이원론으로 완전히 분리되어 있기 보다는, 뫼비우스 띠처럼 연결된다. 모태 예술이었던 음악은 무의식과 몸속에 깊숙이 자리하며, 음악뿐 아니라 미술에서도 여러 장르를 두루 섭렵해온 작품은 공共감각적이다. 이예린의 작품 속 허상simulacre은 현실과 닮은 그림자eikônes와 닮지 않은 그림자phantasma가 모두 존재한다. 작가는 미술이라는 우회로를 통해서 순수한 생성의 세계에 가 닿으려고 한다. The works of Ye leen Lee feature simple and clear interfaces, while they imply abundant diversity. Her representative photo works show mirror-like shadows reflected on the surface of the water, embodying the origin of representation with shadows and mirrors. The pond or puddle made of stagnating water that failed to drain becomes a frame for another world. In the works of Lee, the imaginary world having minimal contact points with the reality becomes maximized in paintings, gets disassembled into abstract elements in drawings, and creates a subtle balance in photographs. However, the reality and the imagination are not separated by dualism but connected like a Möbius strip. Since the artist learned music from inside her mother’s womb, music is deeply rooted in her unconsciousness as well as in her body. The works of Lee are synesthetic, for she has experimented with diverse genres of art besides music. The simulacrum in her works contains both eikônes that is close to the reality and phantasm that is far from the reality. Using art as a detour, the artist attempts to reach a pure world of creation.

Objectives: Ethylene oxide (EtO) is classified as a human carcinogen, but EtO is still widely used to sterilize heat-sensitive materials in hospitals. Employees working around sterilizers are exposed to EtO after sterilization. The aim of the present study was to assess the exposure of EtO level, coupled with occupationally induced micronuclei from hospital workers. The influence of genetic polymorphisms of detoxifying genes (GSTT1 and GSTM1) and DNA repair genes (XRCC1 and XRCC3) on the frequencies of micronuclei in relation to exposure of EtO was also investigated. Methods: The study population was composed of 35 occupationally exposed workers to EtO, 18 student controls and 44 unexposed hospital controls in Korea. Exposure to EtO is measured by passive personal samplers. We analyzed the frequencies of micronuclei by performing cytokinesis-block micronucleus assay (CBMN assay) and GSTM1, GSTT1, XRCC1, and XRCC3 were also genotyped by performing polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP). Results: The frequencies of micronuclei in EtO exposure group, student controls and hospital controls were $18.00{\pm}7.73$, $10.47{\pm}7.96$ and $13.86{\pm}6.35$ respectively and their differences were statistically significant, but no significant differences according to the level of EtO were observed. There was a dose-response relationship between the frequencies of micronuclei and cumulative dose of EtO, but no significantly differences were observed. We also investigated the influence of genetic polymorphisms (GSTM1, GSTT1, XRCC1, and XRCC3) on the frequencies of micronuclei, but there were no differences in the frequencies of micronuclei by genetic polymorphisms. Conclusions: The frequencies of micronuclei in EtO exposure group was significantly higher than control groups. A dose-response relationship was found between the level of EtO exposure and the frequencies of micronuclei, but no statistically differences were observed. We also found that the frequencies of micronuclei were increased according to cumulative EtO level. There was no association of the genetic GSTM1, GSTT1, XRCC1, and XRCC3 state with the frequency of micronuclei induced by EtO exposure.

Nonwovens have been proposed as a sound absorber in applications of home interior textile industry for effective noise control. Honeycomb cell blind textiles have been increasingly used in window covering for noise reduction. In this study, the effect of structural parameters of honeycomb cell-structured spunbond nonwoven on the sound absorption property was investigated. Spunbond nonwovens with various thicknesses, areal densities, and porosities were used, and they were joined in the form of a honeycomb cell structure with various cell widths and cell layering. The sound absorption property of the nonwoven improved with increasing thickness. The porosity of the nonwoven was shown to be proportional to the noise reduction coefficient (NRC). An increased air gap between two layers of the nonwoven shifted the maximum sound absorption coefficient toward a lower frequency range. The honeycomb cell structure was confirmed to contribute to an improvement of the sound absorption property. Layering of the honeycomb cell structure was also shown to be a critical factor in controlling the sound absorption property of the nonwoven.

The purposes of this study were to manufacture sirofil yarn using tencel roving and low melting polyester filaments and to analyze the physical properties of sirofil yarns with yarn count, in order to develop composite yarn for high glossy and luxury textile fabrics. The surface morphology of sirofil yarn was observed with the SEM. Tensile and bending properties of sirofil yarn were examined with the yarn count. The tensile fracture of sirofil yarn was shown with a two-step process. Firstly, tencel yarn having low elongation was broken and then the low melting polyester filaments were fractured with very high elongation. Bending properties of sirofil yarn were measured with the KES-FB. The bending rigidity of sirofil yarn was between that of tencel spun yarn and that of low melting polyester. Also, the surface property of sirofil yarn was evaluated in terms of the hairiness coefficient. It was shown that stress, strain, bending rigidity, bending hysteresis and surface hairiness coefficient of sirofil yarn decreased as yarn count increased.

As COVID-19 has been converted to an endemic with social distancing lifted, people are getting used to new cultures and lifestyles that are different from before. While the world is now adapting to rapidly changing trends, Christian education is facing a crisis without being able to respond to these changes. Therefore, a new Christian education method is now required. The purpose of this study is to suggest a new Christian education method that allows Christians to properly lead a new era as an alternative to Christian education that is experiencing such a crisis. The study also presents the metaverse Christian education platform, which is a detailed and practical method of Christian education, by incorporating the platform and metaverse that are under the spotlight in the post-Corona era into Christian education. Here, the christian educational platform refers to the system, space, and various materials that can make Christian education efficient and smooth. The metaverse Christian education platform consists of 4 stages according to the size of the platform to activate supply and demand within the platform. Stage 1 is a home education platform, Stage 2 is a community education platform, Stage 3 is a regional union education platform, and Stage 4 is an educational mission platform. The last Stage 4, the educational mission platform utilized the metaverse, which is drastically expanding in the present era, as a method of educational mission. It is meaningful that the educational mission has been embodied by providing small churches and the next generation in underdeveloped countries with educational contents, educational materials, online mentors, virtual communities, and real-time educational broadcasts within the educational platform, using virtual spaces in the metaverse.

Escherichia coli O157:H7 infection has been implicated in a number of outbreaks of illness linked to the consumption of foods. Handling raw meat contaminated with E. coli O157:H7 in the kitchen could easily contaminate the surface of cutting boards. Thus, levels of cross-contamination of E.coli O157:H7 from ground beef to cutting boards made of different materials and effects of cleaning methods on reducing E. coli O157:H7 were evaluated. Four types of cutting boards (wood,polyethylene, polypropylene, and acrylic) were selected and contaminated with ground beef inoculated with E. coli O157:H7. Levels of cross-contaminated E. coli O157:H7 on boards were then evaluated. For evaluation of cleaning methods, wiping with dry paper towel , wet paper towel, alcohol paper towel,chlorine paper towel were used to clean the contaminated cutting boards. Initial population of pathogens was 6.09 log CFU/g in ground beef. After 1 h contamination of the inoculated ground beef on the cutting boards, no significant difference were observed in levels of cross-contaminated E. coli O157:H7 depending on the cleaning materials except for the normal polyethylene surface. Order of efficacy in removing E. coli O157: H7 was as follows: alcohol > chlorine > wet > dry paper towel. Cleaning with alcohol sanitizer appeared as the most effective cleaning method for reducing E. coli O157: H7 population on kitchen cutting boards. These results could be used to develop kitchen safety guidelines for preventing foodborne outbreaks.

본 연구는 가로변 지피식물을 중심으로 염화칼슘에 대한 내성과 피해양상을 파악하여 효율적인 가로변 지피식물 적용 및 관리 자료를 제시하고자 실시되었다. 실험구 조성은 염화칼슘 비율 대조구, 0.5%, 1.0%, 3.0%로 구분하여 일반상토 500g을 기준으로 고상처리 하였다. 식물재료로는 가로수 지피식물로 가능성이 있거나 사용되는 수호초, 옥잠화, 마삭줄, 순비기나무, 사철나무, 작살나무를 사용하였다. 결과를 정리하면 토양은 염화칼슘 농도처리에 따라 산도가 증가하였으며, 전기전도도는 지속적으로 감소하였고, 치환성 칼슘 함량은 처리 이후 증가하였으나 실험기간 중 감소하였다. 수호초, 마삭줄, 사철나무는 염화칼슘 비율 0.5%까지 생육 및 생존이 양호한 것으로 나타났다. 옥잠화, 순비기나무는 1.0%까지 생존이 가능한 것으로 나타났으며, 옥잠화는 식재 기반의 수분을 통한 염류의 이동이 가능한 조건에서 가로변의 지피식재로 적용이 가능할 것이라 판단되었다. 작살나무는 대조구를 제외한 염화칼슘 처리구에서 생육이 불량하고 개엽하지 않아 염화칼슘에 대한 민감성이 큰 것으로 나타났다. The purpose of this study was to provide information on management and apply it to a roadside ground cover plant understanding the capacity of calcium chloride in the plant. The experimental group was composed of the ratio control group of calcium chloride, 0.5%, 1.0%, and 3.0% in 500g of soil. Plant materials were selected and measured according to their ecological characteristics such as ground cover plant, Pachysandra terminalis, Hosta plantaginea, Trachelospermum asiaticum, Vitex rotundifolia, Euonymus japonica and Callicarpa japonica. The acidity of the amended soil was increased gradually depending on the treatment and conductivity was continually decreased. The EX-Ca increased after the treatment, but decreased in the middle of the experiment. Pachysandra terminalis, Trachelospermum asiaticum and Euonymus japonica were able to grow and survive at the ratio of 0.5%. Hosta plantaginea and Vitex rotundifolia were able to survive at the ratio of 1.0%. Hosta plantaginea, the possible state can absorb salts due to moisture and, can be applied to ground cover plants in the roadside. The growth and development of Callicarpa japonica was poor and the leaves were open to grow for calcium chloride treatment except the control group. It was concluded that Callicarpa japonica was very sensitive to calcium chloride.
