영어학과 학생들의 스트레스대처방식이 스마트폰 중독에 미치는 영향

윤성규,최연택 한국에니어그램학회 2017 에니어그램연구 Vol.14 No.1

본 연구는 충청지역 소재 S대학 영어학과 학생을 대상으로 1학년, 2학년, 3·4학년으로 구분하 여 학년별 스트레스대처방식 및 스마트폰 중독의 차이를 분석하고 스트레스대처방식이 스마트폰 중독에 미치는 영향력을 분석하였다. ANOVA분석을 실시하여 스트레스대처방식 하위 3유형과 스 마트폰사용중독 하위 4유형의 학년에 대한 차이를 비교분석하였다. 그리고 스마트폰 중독 하위유 형별로 스트레스대처방식 변수의 영향력을 분석하기 위하여 스트레스대처방식 하위 3유형과 개인 특성변수를 독립변수로 하고 스마트폰 중독을 종속변수로 하여 다중회귀분석을 하였다. 학생들의 스마트폰 중독정도는 일반사용자 군에 속하며, 스마트폰 중독을 우려할 수준은 아닌 것으로 나타났다. 학년별 스트레스대처방식에 대한 차이분석결과 의미가 없는 것으로 나타난 반 면, 스마트폰 중독에 대한 차이분석은 유의미한 결과가 나왔다. 스트레스대처방식 하위유형과 개 인특성이 스마트폰 중독에 미치는 영향력 분석결과 문제해결중심대처방식은 모든 하위 유형에서 부(-)적 영향을 미쳤다. 회피중심대처방식은 내성에는 영향을 미치지 않으며, 다른 하위유형에서 모두 정(+)적인 영향을 미쳤다. 학년은 일상생활장애, 금단, 내성에서 부(-)적 영향을 미쳤다. 즉, 스트레스가 발생했을 경우 스트레스를 유발하는 원인에 직접적으로 부딪쳐 문제를 해결하기보다 는 스트레스원인을 회피하는 대처방식을 사용할수록 스마트폰 중독도가 높아지며, 학년의 경우 저 학년일수록 스마트폰 중독 가능성이 높아졌다. The objective of this study is to analyze the difference between stress coping strategy and smartphone addiction among English major students of S University in Chungcheong province. It also attempts to analyze the impact of stress coping strategy on smartphone addiction. In order to test this, it was distinguished by the school year; first year, second year, third year and forth year respectively. ANOVA analysis was conducted to compare the difference between the 3 sub-types of stress coping strategy and the 4 sub-types of smartphone addiction according to students’grade level. In order to analyze the influence of stress coping strategy variables on the sub-types of smartphone addiction, multiple regression analysis was performed using the 3 sub-types of stress coping strategy and individual personality variables as independent variables and the smartphone addiction as a dependent variable. The degree of the smartphone addiction of students belonged to general user group and it was shown that smartphone addiction was not a concern. There was no meaningful difference in the analysis of the difference of the stress coping strategy by the grade level, whereas the difference analysis of the smartphone addiction showed meaningful results. Analysis of the influence of stress coping strategy sub-types and personal characteristics on smartphone addiction showed that problem solving-centered coping strategy had a negative(-) effect on all subtypes. The avoidance-centered coping strategy had no effect on the tolerance and had a positive(+) effect on the other subtypes. The grade level has a negative(-) effect on daily living disability, withdrawal, and tolerance. In other words, when stress occurs, the possibility of smartphone addiction increases when students avoid the stress cause rather than directly addressing the cause of the stress and solving the problem. The lower the grade level, the higher the possibility of smartphone addiction becomes.

Iron Homeostasis Controls Myeloid Blood Cell Differentiation in Drosophila

윤성규,조범식,신민규,페르디난드 코란텡,차누리,심지원 한국분자세포생물학회 2017 Molecules and cells Vol.40 No.12

Iron is an essential divalent ion for aerobic life. Life has evolved to maintain iron homeostasis for normal cellular and physiological functions and therefore imbalances in iron levels exert a wide range of consequences. Responses to iron dysregulation in blood development, however, remain elusive. Here, we found that iron homeostasis is critical for differentiation of Drosophila blood cells in the larval hematopoietic organ, called the lymph gland. Supplementation of an iron chelator, bathophenanthroline disulfate (BPS) results in an excessive differentiation of the crystal cell in the lymph gland. This phenotype is recapitulated by loss of Fer1HCH in the intestine, indicating that reduced levels of systemic iron enhances crystal cell differentiation. Detailed analysis of Fer1HCH-tagged-GFP revealed that Fer1HCH is also expressed in the hematopoietic systems. Lastly, blocking Fer1HCH expression in the mature blood cells showed marked increase in the blood differentiation of both crystal cells and plasmatocytes. Thus, our work suggests a relevance of systemic and local iron homeostasis in blood differentiation, prompting further in-vestigation of molecular mechanisms underlying iron regulation and cell fate determination in the hematopoietic system.

To elucidate the organic matter sources in soft-bottom macrozoobenthos at Tongyeong, Korea, macrozoobenthos and their potential food sources were sampled in May 2004, and their C and N stable isotope compositions were analyzed. In total we collected 128 macrozoobenthic species, which ranged from 465 to 3,775 individuals/$m^2$(average 2,108 ind.$m^2$) in density and from 47.8 to 539.9 gwwt/$m^2$(average 366.0 gwwt/$m^2$) in biomass. Cluster and multi-dimensional scaling analyses indicated that the macrozoobenthic community was divided into two distinct groups. Coastal inner stations, where commercial fish cages were established, were dominated by Amphioplus ancistrotus, Scoletoma longifoila and Tharyx sp., whereas open sea stations were dominated by Chaetozone spinosa, Scoletoma longifolia and Capitella capitata. ${\delta}^{13}C$ values of sedimentary organic matter showed a distinct gradient in the range of -18.4 to $-15.2\%_{\circ}$, with a declining trend from the coastal inner stations to open sea stations. This probably reflects the settling rate of organic wastes such as feces and pellets from fish cages near the coastal inner stations. The macrozoobenthos showed a broad ${\delta}^{13}C$ range from -19.5 to $-8.9\%_{\circ}$ at the coastal inner stations, and a relatively narrow range from -21.3 to $-12.9\%_{\circ}$ at the open sea stations. ${\delta}^{13}C$ values of macrozoobenthos paralleled those of sedimentary organic matter, Our isotope results suggested that macrozoobenthos near the coastal inner stations used organic wastes derived from fish cages along with phytoplankton, whereas the macrozoobenthos near the open sea stations used organic wasters derived mainly from phytoplankton.

관람객 성향에 따른 전시동선 및 연출 전략에 관한 연구

윤성규,주효주 한국실내디자인학회 2018 한국실내디자인학회논문집 Vol.27 No.6

국립과천과학관은 10주년을 맞아 전시를 새롭게 디자인하고 있다. 새로운 전시관을 계획하는데 많은 전문가들이 참여하여 질높은 전시를 제공할 필요가 있다. 관람객의 유형에 따라 전시 동선과 전시 전략이 계획해야 한다. 전시배치구조에 따라 관람객들의 관람유형이 나타난다. 적극적 관람객은 디테일한 탐색이 이루어지기 때문에 관람동선의 형성에 영향이 크지 않다. 소극적 관람객은 통합도에 영향을 받아 높은 통합도의 동선을 따르는 경향이 있다. 적극적 관람객은 많은 과학정보에 민감하지 않지만, 소극적 관람객들은 박물관 피로에 민감하게 반응한다. 이러한 데이터들을 토대로 전시배치와 전시연출전략이 수립되어야 한다. 통합도가 높은 곳의 소극적 관람객을 위해 전시는 쉽고 빠른 이해 중심으로 계획해야 한다. 통합도가 낮은 곳은 적극적 관람객을 위해 많은 전시정보를 전달할 수 있도록 계획해야 한다. National Gwacheon Science Museum has been redesigning exhibitions for the 10th anniversary. Through the surveys and tracking reasurch, the visiotor behavior was quantified and interpreted. Depending on the type of visitors, exhibition Pathway and exhibition strategies should be planned. The types of visitors are shown according to the exhibition arrangement structure. Aggressive visitors are not affected much by the formation of pathway because detailed exploration is done. Passive audiences are affected by the degree of integration and tend to follow a high degree of integration. Passive visitors will be influenced by the degree of integration and choose a high degree of integration. Aggressive visitors are not sensitive to many exhibits, but passive visitors are sensitive to museum fatigue. Based on these data, exhibition layout and exhibition design strategy should be designed. For passive visitors with a high level of integration, it should be planned as an exhibition with easy and quick understanding. In a place with low integration, it should be planned to convey a lot of exhibition information for active visitors.

A total of 60 species of benthic macrofauna was collected by a grab sampler in the eelgrass bed in Kwangyang Bay, Korea. The dominant group was Polychaeta which was composed of 32 species. The dominant species were Platynereis bicanaliculata, Cirriformia tentaculata, Lumbrineris longifolia, and Cirratulus cirratus which accounted for approximately $63.7\%$ of the total numbers of benthic macrofauna. Seasonal variations in both species composition and abundance of the benthic macrofauna were major characteristics in the study area. Seasonal peak of number of species and abundance occurred in summer. And the lowest abundance occurred in winter. Seasonal dominant species were Platynereis bicanaliculata, Cirriformia tentaculata, Lumbrineris longifolia in spring and summer, and Cirratulus cirratus, Capitella capitata, Opisthobranchia in fall.
