Purpose: This study aimed to examine the influence of depression on health behaviors (daily smoking, serious drinking, having physical activity and breakfast among Korean adolescents. Methods: The data for the study were obtained from the 18th (2022) Korea Youth Risk Behavior Survey. The final sample consisted of 51,847 cases after excluding missing data. Multivariate logistic regression, Multilinear regression, Chi square, t-test, and an analysis of variance were used for data analysis. Results: Adolescents who experienced depression were 2.35 times more likely to smoke daily, 2.97 times more likely to drink seriously. As adolescents were more depressed, the number of days they had breakfast in the past 7 days decreased (B=-0.34, p<.001). However, in contrast to expectations prior to the study, depression caused to increase the number of days per week spent engaging in physical exercise (B=0.24, p<.001). It was believed that the school environment(physical education, going to and from school acted as a moderating variable in the relationship between depression and physical activity of adolescents. Additionally, it could be explained that depressed adolescents might try to relieve their depression through physical activity rather than focusing on their studies. Conclusion: This study was conducted to test the hypothesis that adolescent depression would negatively impact on health behaviors (such as drinking, smoking, and nutrition). It was found that adolescent depression increased the likelihood of daily smoking and serious drinking, but caused to skip breakfast. Our findings suggest that in promoting the physical health of adolescents, managing depression is a crucial factor.

From the climate change scenario experiments of 21 models participating in Coupled Climate Model Inter-comparison Project Phase 6, future changes of sea surface temperature (SST) and Kuroshio in the Northwest Pacific were analyzed. The spatial feature of SST change was found to be related to the change of the current speed and spatial distribution of Kuroshio. To investigate the relationship between the change in latitude of the Kuroshio extension region, which flows along the boundary between the subtropical gyre and the subarctic gyre in the North Pacific, and the large-scale atmospheric circulation due to global warming, the zero-windstress curl line for each climate change experiment from 9 out of 21 models were compared. As the atmospheric radiative forcing increases due to the increase of greenhouse gases, it was confirmed that the zero-windstress curl line moves northward, which is consistent with the observation. These results indicate that as the Hadley Circulation expands to the north due to global warming, the warming of the mid-latitudes to which the Korean Peninsula belongs may be accelerated. The volume transport and temperature of the Tsushima Warm Current flowing into the East Sea through the Korea Strait also increased as the atmospheric radiative forcing increased.

정수연,한정한 한국지역학회 2011 지역연구 Vol.27 No.4

본 연구는 최근 블루골드로 평가받고 있는 물산업을 대상으로, 물산업의 공급측면에서의 적정규모를 추정하였다. 분석자료로는 2009년 물관련 기업별 재무제표내의 매출액, 유형고정자산, 고용자수를 이용하였다. 모형으로는 Zellner & Revankar(1969)와 A. Zellner and H. Ryu(1998)의 연구에서 제안된 일반화된 생산함수(Generalized Production Function) 및 그에 대응하는 규모의 보수함수(return to scale function), 평균비용함수(cost function)를 이용하여 물산업(water industry)의 평균비용과 최소효율규모(minimum efficient scale)를 추정하였다. 분석자료로는 2009년 기준 물산업에 속한 총 26개의 기업자료들이 활용되었다. 본 논문의 분석결과 생산효율성의 관점에서 물산업의 적정규모는 약 2천6백억원으로 나타났다. 또한 현재 대부분의 물산업기업들은 규모의 보수 체감상태여서, 아직 최소효율규모에는 도달하지 못한 상태라고 판단할 수 있었다. This study examines the water industry, which has been described as a 'blue gold' business, and attempts to estimate the optimal size of the industry from a supply standpoint. The data analyzed include sales, tangible fixed assets, number of employees, and other figures from the 2009 financial statements of water industry companies. The models used include the Generalized Production Function (GPF) introduced by Zellner &Revankar (1969) as well as A. Zellner &H. Ryu (1998) in addition to the corresponding Return to Scale Function, and the Average Cost Function in order to estimate the water industry's average costs and Minimum Efficient Scale (MES). The analysis is based on 2009 data from a total of 26 companies in the water industry. The results of this study suggest from a production efficiency standpoint that the optimal size of the water industry is approximately 260 billion Korean Won. In addition, most companies in the industry at present are reducing worker compensation, so it can be surmised that the industry has not yet reached MES

Reliable and valid diagnostic screening tools in the primary care setting enable accurate estimation of depression in individuals at risk or in need of treatment, and provide patients with an opportunity to receive optimal treatments. Although there have been extensive studies on screening tools for depression used in domestic mental health settings, there is little consideration and lack of a thorough review of the diagnostic validity of screening tools. In the current review, we selected 13 representative screening tools for depression which were evaluated in a total of 19 validation studies conducted in Korea. We summarized DSM-5 target domains, diagnostic indices, sensitivity, specificity, cut-off scores, and diagnostic validity information for each tool. Finally, the depression measurement expert group was constituted to evaluate the current status of screening tools for depression, and their recommendations for a new screening tool were summarized. This study was conducted as part of the Mental Health Technology Development project to develop the Korean screening tool for depression (K-DEP).

2015 개정 과학과 교육과정에 따른 고등학교 생명과학II 교과서의 탐구활동 유형 분석

정수연,장정호,Jeong, Soo Yeon,Chang, Jeong Ho 경북대학교 과학교육연구소 2019 과학교육연구지 Vol.43 No.1

The types of inquiry activities included in Life Science II textbooks under the 2015 revised science curriculum were extracted and compared with those of six major and five different publishing companies. The fact that the number of investigation discussions and presentations (IP) increased and the expressions (EX) were included in each unit was interpreted as sufficient to transform the classroom instruction in the 2015 revised science curriculum into student-centered activities. The type of inquiry activities in student-centered activities such as experiment observation, simulation activities, investigation discussions, and presentations accounted for about 41% more than the 27% of 2009 revised science curriculum. However, since data interpretation type is still the largest, it is necessary to reduce the types of data interpretation and to increase the number of types of simulation activities and expressions in order to expand students' creativity and thinking ability when textbook development is needed in the future. In addition to the development of biotechnology, teachers need to reconstruct diverse science materials for each textbook and then use them for students to induce balanced thinking, and try to expand expressive power, creativity, logic, and critical thinking skills.

생체모방기술에 의한 건물외피 에너지 저감 연구동향 및 제언

정수연,한소원,황지영,이행우 사단법인 한국융합기술연구학회 2023 아시아태평양융합연구교류논문지 Vol.9 No.11

에너지 사용량 급증 문제는 지속적으로 심각해지고 있으며, 주 에너지원으로 사용하였던 화석연료의 고갈로 인해 그 심각성은 더욱 악화되고 있다. 이러한 문제의 주요 원인은 건물 부분의 에너지 사용량 증가를 뽑을 수 있으며, 이를 해결하고자 건물 에너지 저감을 위한 다양한 연구와 기술개발 연구가 이루어지고 있다. 특히 건물 부분의 에너지 사용량은 건물 외피의 성능과 비례하는 만큼 건물 외피의 성능개선은 건물 에너지 개선에 있어서 중요한 연구이다. 이를 통하여 최근 증가하고 있는 생체모방기술을 적용한 건물 외피에 대한 연구의 경향과 수준을 파악하는 것은 중요하다고 할 수 있다. 이에 본 연구는 일차적으로 수행된 생체모방기술 적용 건물 외피에 대한 연구를 고찰함으로써 선행 연구의 연구 경향을 분석하고자 한다. 또한, 생체모방기술이 적용된 건물 외피에 대한 후속 연구의 방향성을 제공하며 추후 기초자료 구축을 목적으로 한다. 본 연구는 생체모방기술이 적용된 건물 외피 관련 연구 경향을 분석하기 위하여 생체모방, 건축 및 건물 외피를 주요 키워드로 하는 선행연구 논문을 선정하였다. 또한, 본 연구는 생체모방기술 적용 건물 외피 관련 선행연구의 경향을 분석하는 것이기에 생체모방기술의 적용 범위, 적용 요인, 가동 유무, 심미적 요인, 에너지 저감 및 경제성을 분석하는 내용을 주요하게 설정하였다. 이에 대한 결론은 다음과 같다. 1) 건축 및 건물외피 분야에서의 생체모방기술 연구는 의료 및 로봇 첨단 분야에 대비하여 상대적으로 부족한 실정이다. 생체모방기술은 건물 외피에 적용하기에 있어서 비용적 문제가 크다는 것도 간접적인 원인이다. 2) 선행연구는 자연현상을 모방한 건물 외피 연구가 수행되고 있으며 추가적으로 이를 구현하기 위한 가동 기술이 접목되고 있다. 이러한 생체모방기술이 적용된 건물외피는 건물 외피의 행태와 가동을 접목하여 심미적인 효과가 실현되고 있는 것으로 판단된다. 3) 생체모방기술이 적용된 건물 외피의 선행연구는 전체적으로 에너지 부문의 검토가 부재한 것으로 분석된다. 또한, 유지 및 관리를 위한 경제성 검토가 이루어지지 않는다는 한계를 가지고 있으며, 향후 많은 연구 수행 이후 그 경향을 검토해야 할 것으로 사료된다. Increasing energy demands are becoming a serious problem as we continue to rely on fossil fuels as our primary energy source. One of the main causes of this problem is the increasing energy consumption in the building sector, and many studies are being pursued to address this issue. In particular, as the energy used in buildings is proportional to the performance of building envelopes, research on improving the performance of building envelopes is significant in saving building energy. Therefore, it is crucial to understand the trends and level of research on building envelopes using biomimetics, a field that has seen significant growth in recent years. In response, this study analyzed the research trends of previous studies on building envelopes using biomimetics. The purpose was to construct basic data and provide directions for subsequent research on similar technologies. Previous studies using keywords such as biomimetics, architecture, and building envelopes was selected to analyze research trends related to building envelopes using biomimetics. It also covers the scope of application, application factors, operation, aesthetic factors, energy savings, and economics of biomimetic technologies. The main findings are as follows. 1) There is a lack of research on biomimetics in architecture and building envelopes compared to high-tech fields such as medical care and robotics. One indirect reason is the significant cost-related issues of biomimetics when applied to building envelopes. 2) Most previous studies have been focused on building envelopes that mimic natural phenomena and integrating operational technologies to implement them. Building envelopes integrating such biomimetic technologies realize aesthetic effects by combining the behavior and operation of building envelopes. 3) Most previous studies on building envelopes using biomimetics did not review energy consumption. They also did not cover the economic aspects related to maintenance and management, which future studies should review.

SF6 and O2 Effects on PR Ashing in N2 AtmosphericDielectric Barrier Discharge

정수연,황용석,김곤호,김지훈 한국전기전자재료학회 2006 Transactions on Electrical and Electronic Material Vol.7 No.4

Photo Resist (PR) ashing process was carried out with the atmospheric pressure - dielectric barrier discharge (ADBD) using SF6/N2/O2. Ashing rate (AR) was sensitive to the mixing ratio of the oxygen and nitrogen of the blower type of ADBD asher. The maximum AR of 5000 Å/min was achieved at 2 % of oxygen in the N2 plasma. With increasing the oxygen concentration to more than 2 % in the N2 plasma, the discharge becomes weak due to the high electron affinity of oxygen, resulting in the decrease of AR. When adding 0.5 % of SF6 to O2 / N2 mixed plasma, the PR AR increased drastically to 9000 Å/min and the ashed surface of PR was smoother compared to the processed surface without SF6. Carbon Fluorinated polymer may passivate the PR surface. It was also observed that the glass surface was not damaged by the fluorine.
