  • Background: This study was conducted to identify the level of gender sensitivity and gender equality consciousness among dental hygiene students and to confirm the necessity of gender equality programs in the curriculum. Methods: A self-report questionnaire was conducted with some dental hygiene students using the Gender Sensitivity tool and Korean Gender Egalitarianism Scale for Adolescents (KGES-A). Results: First, the gender equality consciousness of the students who took women's studies was high in the areas of educational life and socio-cultural life, and that of the subjects of grandparent families and Catholic was found to be high in the domestic life area. Second, the gender sensitivity of the subjects who took women's studies was found to be high in all sub-areas. In addition, the gender sensitivity of females was higher in the areas of sexual identity, non-violence, and self-reflection than that of males. That of 4-year college students was higher in the areas of sexual identity, openness to gender roles, and non-violence than that of 3-year college students. In addition, the gender sensitivity of Catholic students was high in the areas of sexual identity and openness to gender roles. Third, gender equality consciousness was found to have an effect depending on whether subjects took women's studies, family type, family type, and religion, and gender sensitivity was found to have an effect depending on whether subjects took women's studies or gender. Conclusion: Since dental hygienist is a profession that targets humans, education that can instill equal awareness and values of humans is important. To inspire gender sensitivity and gender equality consciousness in a prospective professional, it is necessary to conduct programs and education related to gender intelligence within dental hygiene curriculum.

  • 수중에서는 공기 중에서의 신호 전달과는 달리 음파에 의해 신호가 전달된다. 또한 음파는 해수면, 해저면, 수온, 염분 등 다양하고, 복잡한 수중 환경 특성으로 인해 직접 혹은 반사 등의 간접 경로로 전달된다. 이런 복잡한 수중 환경에서 잠수함의 생존성과 적 함정으로부터 피탐 위험성의 정도를 파악하기 위해 반드시 수행하는 시험이 수중방사 소음 측정 시험이다. 수중방사 소음 측정을 위한 여러 조건들 중 가장 중요한 것이 측정 센서와 잠수함과의 거리이다. 보통 수중방사 소음의 음원 준위 측정은 측정 센서와 잠수함과의 최근접 점(CPA : Closet Point of Approach) ±수 미터내에서 이루어져야 측정한 음원 준위 값을 유효한 것으로 간주한다. 이에 본 연구에서는 다중 경로 신호들의 도플러 천이 주파수 및 다른 도달 시간 차 신호를 추정하는 방법으로 수중음원에 대한 거리 추정 방법을 제시하였다. 제안한 방법의 타당성을 고찰하기 위해 수중 채널 전달 모델 기반의 모의실험을 수행하였다.

  • In this study, Mitigation of Potential-induced degradation (PID) for PERC solar cells using SiO2 Structure of ARC layer. The conventional PID test was conducted with a cell-level test based on the IEC-62804 test standard, but a copper PID test device was manufactured to increase the PID detection rate. The accelerated aging test was conducted by maintaining 96 hours with a potential difference of 1000 V at a temperature of 60℃. As a result, the PERC solar cell of SiO2-Free ARC structure decreased 22.11% compared to the initial efficiency, and the PERC solar cell of the Upper-SiO2 ARC structure decreased 30.78% of the initial efficiency and the PID reliability was not good. However, the PERC solar cell with the lower-SiO2 ARC structure reduced only 2.44%, effectively mitigating the degradation of PID. Na+ ions in the cover glass generate PID on the surface of the PERC solar cell. In order to prevent PID, the structure of SiNx and SiO2 thin films of the ARC layer is important. SiO2 thin film must be deposited on bottom of ARC layer and the surface of the PERC solar cell N-type emitter to prevent surface recombination and stacking fault defects of the PERC solar cell and mitigated PID degradation.

  • Background: Understanding the habitat characteristics of the endangered Siberian flying squirrel Pteromys volans is the first step in conserving and managing the forests it requires for nesting, gliding, and feeding. Therefore, in the present study, we characterized the habitats of P. volans using GIS analysis of 411 forest sites in South Korea where fecal droppings were found. Results: Fecal signs of P. volans were found in various regions in South Korea, including the Baekdudaegan Mountains. GIS analysis with six environmental layers (vegetation type, wood-age class, diameter at breast height [DBH], crown density, elevation, and distance from stream) revealed that fecal signs of P. volans were more frequently found in broad-leaved deciduous forests (42%) located 200-399 m above sea level (43.1%) and 0-199 m from the nearest stream (53%), with 5th class wood-age (35.3%), middle size class DBH (51.1%), and high crown density (71%). Conclusions: The present study provides information on the biotic and abiotic characteristics of P. volans habitats. In South Korea, the fecal droppings of P. volans were found predominantly old deciduous broadleaf forests. Further studies are needed to reveal whether the more frequent occurrence of P. volans dropping in broadleaf forests may be due to a particular preference of this species for the forests or to a simple reflection of the area of the broadleaf forests occupying a much larger area than other forest types in Korea.

  • The article deals with issues related to the tradition of carpet production on the territory of Kazakhstan where, for the most part, tribes engaged in nomadic livestock raising lived. Analyzing the technological component of this traditional craft, the author focuses on the main factor that influenced carpet weaving along with arts and crafts-the nomadic method of production of the Kazakhs. The study of the ideological component that accompanies the process of making various types of carpets allows us to conclude that it has a sacred meaning and subordination to myth, rite, and ritual. At the mythmaking level, the process of making carpets, like any other activity among nomads, personified the process of creating the world, the marriage of Kok-Tengri (Heaven) and Zher-Su (Earth), and the creation of the Cosmos from Chaos. The process of carpet weaving, as well as the process of making felt, symbolized the act of creation, the marriage of Heaven and Earth, and male and female principles. The study of various types of ornaments that Kazakhs and their ancestors used to decorate carpets allows us to conclude that the ornament applied to carpet products was the bearer of the most valuable information about the mythological worldview of the people. Carpets in their structure reproduced the structure of the Universe, which has a binary, ternary, and quaternary system. The ornament has turned into a kind of coded text, reflecting ideas about the cosmogonic structure of the Universe and an awareness of the harmony of the world. The location of Kazakhstan on the northern routes of the Sogdian Road (Great Silk Road) allowed the spread of various ideas, due to which carpet weaving was influenced by other peoples in technical and stylistic design.

  • Debates continue to multiply on the definition and rationale of Southeast Asia as a region and on the utility of the multidisciplinary field of area studies. However, we have now entered a post-colonialist, post-Orientalist, post-structuralist stage of reflection and re-orientation in the era of globalization, and a strong tendency on the part of insiders to pose these issues in terms of an insider-outsider dichotomy. On the one hand, the study of Southeast Asia for researchers from outside the region has become fragmented. This is for very obvious reasons: the strengthening and re-energizing of academic disciplines, the increasing popularity of other non-regional multidisciplinary studies, and the entry of globalization studies into our field of vision. On the other hand, how has the local Southeast Asian academy addressed these major issues of change in conceptualizing the region from an insider perspective? In filling in and giving substance to an outsider, primarily Euro-American-Australian-centric definition and vision of Southeast Asia, some local academics have recently been inclined to construct Southeast Asia in terms of the Association of Southeast Asian Nations (ASEAN): a nation-state-based, institutional definition of what a region comprises. Others continue to operate at a localized level exploring small-scale communities and territories, while a modest number focus on sub-regional issues (the Malay-Indonesian world or the Mekong sub-region are examples). However, further reflections suggest that the Euro-American-Australian hegemony is a thing of the past and the ground has shifted to a much greater emphasis on academic activity within the region. Southeast Asia-based academics are also finding it much more important to network within the region and to capture, understand, and analyze what Chinese, Japanese, and Korean scholars are saying about Southeast Asia, its present circumstances and trajectories, and their increasingly close involvement with the region within a greater Asia-Pacific rim. The paper argues that the insider-outsider dichotomy requires considerable qualification. It is a neat way of dramatizing the aftermath of colonialism and Orientalism and of reasserting local priorities, agendas, and interests. But there might be a way forward in resolving at least some of these apparently opposed positions with recourse to the concepts of culture and identity in order to address Southeast Asian diversities, movements, encounters, hybridization, and hierarchies.

  • In Korea, there are many attempts to automate architectural design tasks, focusing on government-led national R&D projects and private operators, in order to enhance global competitiveness and productivity of the building service industry. However, according to a survey of architectural design office practitioners, only 25% (9 out of 37) have used it, suggesting that there are fewer cases of practical use in the field compared to research and investment in automation technology development, and there are discrepancies between automation and technology development items required in the field. In this study, the priority of automation of planning and design work of architectural design office practitioners is derived, and a comparative analysis is conducted with domestic architectural design automation service items based on the priority. A survey was conducted on practitioners of domestic architectural design offices to derive automation priorities for 19 items of architectural planning and design work. Based on the derived priorities, the degree of reflection of the working-level automation needs of domestic services was confirmed by comparing them with the domestic architectural planning and design automation service items. As a result, it was confirmed that domestic architectural planning and design automation services did not properly reflect the priority of planning and design work automation of architectural design office practitioners. This suggests that it is necessary to reflect the priorities derived in this study in technology development in order to increase the cases of practical use of the automation technology in the working environment and improve the productivity of service.

  • 수중에서의 통신은 해수면과 해저면 등에 의한 신호의 반사가 생겨 다중경로 현상이 발생한다. 이러한 다중경로의 영향으로 신호는 왜곡되고 원활한 수신을 방해하게 된다. 이에 각종 통신시스템에서 적용되고 있는 여러 가지 채널 부호 방법을 모델링된 수중통신채널에 적용하여 그 성능을 확인하였다. 그 결과 다중경로에 의한 오류의 특성은 랜덤오류의 특성을 가지기 때문에 인터리버의 효과는 거의 볼 수 가 없으며, 수중채널에서 다중경로에 의해 야기된 오류마루 현상을 극복하기 위해서는 LDPC 부호와 같은 강력한 오류 정정 부호가 요구되며, RS 부호등을 연접하여 사용할 경우 더욱 우수한 성능을 보이는 것을 확인할 수 있었다.
