TV媒體가 兒童의 攻擊性 發達에 미치는 影響

申允澈,裵珍洙 진주교육대학교 1986 論文集 Vol.30 No.1

Few tropics have attracted as much theoretical and empirical attention over the past score as the development and regulation of aggressive behavior permeated by the TV viloence viewing. In this pacer we intended to overview the ambivalent effects of TV-media, the relationship between TV violence viewing and aggressive behavior development of the children through the literatures according to the types of research, and after that suggest some implipications to decrease and prevention of aggression. In light of the review we draw the following conclusions. 1) Research has demonstrated that TV plays a role in the positive effect and negative effect as well according to the TV programs, 2) Although multiple theories have been explored to explain the development of aggression derived from the TV violence viewing, only one theory can't be done it completely. 3) Though the results gained from the laboratory experiments about the effects of TV violence viewing and the viewer's aggression are inconsistent, they have helped to identify the range of circumstamces under which it is possible to find an effect on viewer aggression. 4) While field experiments haute found either no effect or awn effect of less aggression in the group that viewed violence compared to a group that viewed neutral films, the remaining majority of these studies has provided qualified evidence that viewing of violence leads to an increase in viewer aggression. 5) Most of the correlational study have not reached the conclusion that there is a consistent or, small positive correlation between viewing TV violence and aggression. But there is little evidence that in natural settings viewing TV violence cause people to be more aggressive. 6) There are many intervening variables in determining the TV violence viewing and aggressive behavior, that is, age, sex-typing, identification and fantasy wish the TV characters, viewer's predisposition, parents influence, etc.

This study was conducted to investigate wintering ecology and habitat using pattern of cranes for sound protection and management of the birds and their habitat near the Demilitarized Zone(DMZ) of Cheolwon, South Korea. Distribution of cranes seemed to be affected by road construction and human activity. Dried rice paddy was mainly habitat type of cranes in Cheolwon area. Gleaning was dominant behavior during day time. Ratio of alert was increased in afternoon. There was difference in time budget of behavior between red-crowned and white-naped cranes. For the stable wintering of cranes, minimum change of habitat, decrease of human disturbance and stable food maintenance would be needed in Cheolwon area.

이윤배,신상철 순천향대학교 부설 산업기술연구소 1999 순천향 산업기술연구소논문집 Vol.5 No.1

In order to reduce carbon dioxide, poly(propylene carbonate) has been synthesized. The alternating copolymers has been obtained from carbon dioxide and propylene oxide using zinc glutarate as a catalyst have different glass transition temperature depending on their synthetic method. The different size of ether block and carbonate block has been known to play imortnat role. The change of structure of PPC were observed under different condition. The glass transition temperature increase as the size of ether block decrease.

This study was conducted to investigate the biomechanical characteristics of the gait pattern in an amputee for the purpose of improving the proper gait posture and designing the prosthetic. The subjects were six males amputees and one normal person. The ground reaction force was measured using AMTI force platform. The conclusions were as follows; 1. In case of amputee group, the ground reaction force was revealed in specific figure according to position in which they used the prosthetic, whereas in case of normal person the ground reaction force was revealed in the figure of two humps in regard of vertical axis. 2. In case of amputee group, the ground reaction force in time between fight foot contact and left foot contact was deviated from a figure of rectangle, whereas in case of normal person the ground reaction force was revealed in the figure of rectangle. 3. In case of amputee group, the ground reaction force referred to both feet angle point of view was revealed in irregular figure, whereas in case of normal person the ground reaction force was revealed about 47。

Risk Analysis of Thaw Penetration Due to Global Climate Change in Cold Regions

Bae, Yoon-Shin Korean Society of Hazard Mitigation 2009 한국방재학회논문집 Vol.9 No.2

지구기후모델을 이용하여 예측된 (1) 물성치와 (2) 현재 및 미래의 표면 에너지 입력상수의 가변성을 고려한 동결 및 융해깊이를 예측하기 위하여 확률론적 접근법이 도입되었다. 확률론적 접근법을 예시하기 위하여 극지방에서의 융해깊이 예측을 고려해보았다. 특히 확률론적 융해깊이 예측을 위하여 몬테카를로 시뮬레이션과 함께 Stefan 공식이 사용되었다. 시뮬레이션 결과는 물성치의 가변성을 보여주었다. 표면 에너지 입력상수와 온도 데이터는 융해깊이를 예측하는데 상당한 불확실성을 야기시킬 수 있다. A probabilistic approach may be adopted to predict freeze and thaw depths to account for the variability of (1) material properties, and (2) contemporary and future surface energy input parameters(e.g. air temperatures, cloud cover, snow cover) predicted with global climate models. To illustrate the probabilistic approach, an example of the predicted of thaw depths in cold regions is considered. More specifically, the Stefan equation is used together with the Monte Carlo simulation technique to make a probabilistic prediction of thaw penetration. The simulation results indicate that the variability in material properties, surface energy input parameters and temperature data can lead to significant uncertainty in predicting thaw penetration.

The Analysis of Lateral Movement at the Top of Retaining Wall in the Downtown Area

Bae Yoon-Shin(배윤신) 한국지반환경공학회 2009 한국지반환경공학회논문집 Vol.10 No.3

대도시에서의 공사는 외부방향이 아닌 상부로 진행되기 때문에 현장의 벽면 움직임은 매우 중요하다. 고층 구조물은 주차장을 위한 여분의 공간 확보뿐 아니라 건물의 잠재적 침하를 줄이기 위하여 일반적으로 깊은 굴착을 수반한다. 이러한 대형 굴착은 깊은 심도에 따른 횡방향 지중압력에 견디기 위한 견고한 브레이싱 시스템을 필요로 한다. 벽체 움직임은 잠재적인 인접 구조물의 침하를 허용하기 때문에 sheetpile 이나 diaphragm wall과 같은 옹벽구조물의 변형을 예측하는 방법은 매우 중요하다. 사례들을 분석하고 측정된 벽체 변형은 경험적 도표로부터 예측된 값들과 비교되었다. The movement of in-situ walls has become very important as construction in large cities moves upward, instead of outward. Tall structures typically have deep excavations not on1y to provide extra space for parking, but also to reduce the potential settlement of the building. These large excavations require a robust bracing system to resist the lateral earth pressures as the depth increases. Methods to predict deflections of the retaining systems are of utmost importance because wall movements allow potentia1 settlement of adjacent structures. Case studies will be analyzed and measured waI1 def1ections will be compared with predictions from empirica1ly derived charts.

Modified Equivalent Radius Approach for Soil Damping Measurement in Torsional Testing

Bae. Yoon-Shin 한국방재학회 2008 한국방재학회논문집 Vol.8 No.2

Determination of strain associated with shear modulus and damping ratio during torsional test is complicated. This is due to nonuniform stress-strain variation occurring linearly with radius in a soil specimen in torsion. A conventional equivalent radius approach proposed by Chen and Stokoe appears to be adequate for evaluating strain associated with shear modulus at low to intermediate strain levels. This approach is less accurate for damping measurement, particularly at high strain. Modified equivalent radius approach was used to account for the nonuniform stress-strain effect more precisely. The modified equivalent radius approach was applied for hyperbolic, modified hyperbolic, and Ramberg-Osgood models. The results illustrate the usefulness of the modified equivalent radius approach and suggest that using a single value of equivalent radius ratio to calculate strains is not appropriate.

<P>Bombyxamycins A and B (<B>1</B> and <B>2</B>) were discovered from a silkworm gut <I>Streptomyces</I> bacterium. Spectroscopic analysis and multiple-step chemical derivatization identified them as 26-membered cyclic lactams with polyene features. Bombyxamycin A showed significant antibacterial and antiproliferative effects. The bombyxamycin biosynthetic gene cluster was identified by genetic analysis. Gene deletion experiments confirmed that the cytochrome P450 BomK is responsible for the generation of <B>2</B>, which unprecedentedly bears tetrahydrofuran in its macrocyclic ring.</P> [FIG OMISSION]</BR>

Yoon-Shin Bae 한국재난정보학회 2012 한국재난정보학회 논문집 Vol.8 No.3

경량혼합토는 건설잔토나 준설토 및 현장에서 발생하는 점토나 실트질 흙을 사토처리 하지 않고 현장에서 유용할 수 있는 매우 경제적이고 환경친화적인 재료이다. 최근에는 페자원(폐타이어가루, 왕겨)을 경량혼합토에 첨가하는 건설재료 재활용에 관한 연구가 진행 중에 있다. 본 연구에서는 경량혼합토를 제작하기 위해 필요한 배합설계변수인 원료토의 중량, 함수비 및 기포재와 첨가할 물의 양, 그리고 강도를 발현하기 위하여 필요한 고화재로서 시멘트첨가량에 대한 최적의 배합설계에 대한 분석을 하였다. 이를 위하여 일축압축시험에 의한 응력-변형 거동과 양생기간 및 성분비에 따른 강도분석, 폐기물 성분비에 대한 실험강도 비교분석을 수행하였다. 마지막으로, 합리적이고 경제적인 배합비 산출을 위하여 경량혼합토의 목표강도를 결정하고 최적의 배합설계 변수를 제시하였다.
