The purpose of this manuscript was to investigate the effects of issue involvement and relation of perceivers to comparison targets on the magnitude of third person perceptions. The investigation was expected to help us to understand the underlying process of third person effect hypothesis. Data was collected from adult residents in Ohio, United States by telephone survey in 2003(n=524). Like most other third person effect studies, this study supported the hypothesis: Respondents perceived more media effects on others than themselves for both 'Negative media portrayals of smokers' and 'News coverage of Roman Catholic priest's sexual scandals'. Results of five hypothesis tests suggest that when relationship between a perceiver and a particular comparison target is present third person perception is explained more by cognitive components than motivational components. In this case, third person perception varies with comparison target's issue involvement while it is independent of social distance between the perceivers and the comparison target. Also, perceivers' issue involvement positively correlates with the magnitude of third person effect. Based on the results, it is concluded that when perceives or a comparison target is involved in a message cognitive processes accounting for the relationship can impact the magnitude of third person effect. An important theoretical implication of the study is that third person effect is, to some extent, related with framing effect and priming effect.

This paper aims to examine the third-person effect(TPE) of hate comments on online news, and analyze how the issue-relevant audience factors as well as the characteristics of the online message have influence on the TPE. More specifically, based on the distinction between hateful and logical comments regarding the issue of illegal immigration, the authors have conducted an online experiment that compares how the message-related features, i.e., ways of expressing the ideas, lead to the difference in TPE. Analysis was also conducted with regards to how political orientation and discriminatory predisposition to immigrants among the audiences, have different impacts on the TPE. The 479 participants in the experiments were randomly assigned to experimental group(exposed to hate comments) or control group(exposed to logical comments). The results reveal that the TPE of hate comments is higher than that of logical message. The same message proved to be more effective for news users with liberal orientation and discriminatory predisposition. The significance of this paper lies in that it has examined the effect of online hate comments in a rigorous experimental setting. Also the research further elaborated on the audience-related variables, for which the previous studies tended to focus those on the general psychological level rather than relate them more specifically to the issues.

Based on the third-person effect hypothesis, this study conducted a nation-wide online survey to assess how Korean voters perceived the mass media's effect on the candidates' image and voting behavior during the 17th presidential election. The research results showed that the voters tended to perceive that the mass media such as newspaper, television and the Internet had a greater effect on others than on themselves with regards to the formation of the three candidates' images. The third-person effect on the voting behavior was also revealed differently in terms of the medium according to age and political tendency of the voters. For instance, the younger and liberal voters were likely to see newspaper as having a greater influence on other voters' choice of candidate, while the older voters saw TV as having a greater effect on other voters. The conservative tendency did not affect the perception of the voters at all. Another noteworthy result was that personal characteristics of the candidates' images such as appearances and communication skills did not affect the voters' behaviors in the election process.

난류상태로 유동중인 고분자 수용액은 순수 용매만의 경우에 비교할 때 동일유량에서 초기에 높은 마찰 저항감소효과를 보이며, 이러한 마찰저항감소효과는 펌프의 펌핑능력 증대로 큰 경제적 이익을 가져다준다. 그러나, 고분자 수용액은 그 극적인 마찰저항감소효과에도 불구하고 유동중에 가해지는 기계적 에너지, 열에너지 등에 의해서 초기의 높은 마찰저항감소효과를 점차적으로 상실하게 되기 때문에, 고분자 수용액의 퇴화를 완화시키기위한 연구가 필요하다. 따라서 본 연구에서는 기계적 퇴화특성이 비교적 강한 합성고분자와 계면활성제의 농도합계를 100wpm 으로 고정하고 비율을 11가지로 세분화하여 , 1$0^{\circ}C$의 온도에서 유속 1.5m/sec , 3.0m/sec 및 4.5m/sec 에 대한 퇴화경향을 알아보는 실험을 수행하였으며, 각 조건에서 합성고분자와 계면활성제의 적정비율을 관찰하였다. 실험 결과, 각 속도에서 시간에 따른 퇴화경향은 고속에서 기계적 에너지에 대한 퇴화를 볼 수 있었고, 계면활성제와 합성고분자를 혼합하여 첨가했을 경우 저온에서도 퇴화완화효과가 있음을 확인하였다.

The relationship between dietary intake and vitamin/mineral supplement usage was examined in 706 adolescent girls who were high school students. 43.8% of subjects used vitamin/mineral supplements during one year. The higher the family income and parents education level, the higher percentage of vitamin/mineral supplement usage was. But there was no significant difference between grades and scores. And vitamin/mineral supplement usage was higher int he thin and obese groups than the average weight groups. Nutrition knowledge and food habit did not affect vitamin/mineral supplement usage. Calorie intakes of vitamin/mineral supplement users and nonusers were similar. However, independent of the supplements, the diets of supplement nonusers contained significantly more dietary protein, vitamin A, vitamin $B_2$, niacin, vitamin C, and calcium than the diets of the users. A considerable portion of both the users and nonusers had dietary intakes of less than 2/3 of the Recommended Dietary Allowances for vitamin $B_1$, vitamin $B_2$, niacin, calcium, and iron. Vitamin/mineral supplement nonusers generally consumed a more vitamin, mineral from diet. Reasons for taking supplements were to take energy, advice and illness.

적은양의 분자량이 큰선형 고부자를 수용액에 첨가함으로서 얻어지는 마찰저항가소 연구가 rotating disk 장치를 이용해 수행되었다. 마찰저항 감소제로 poly(ethylene oxide)와 poly(acrylamide)를 사용하였으며 고분자 분자량 고분자 농도, disk 의 회전속도 및 온도 등 여러 가지 인자에 대한 마찰정항감소의 의존성을 연구하였다. 또한 마찰저항 감소 효과와 고분자 용액의 점도평균 분자량을 동시에 측정함으로서 고분자 퇴화에 대한 연구도 수행하 였다. 마찰저항감소는 고분자 농도가 증가함에 따라 임계농도에 도달할때까지 증가하였고 낮은 농도에서는 분자량이 큰 고분자일수록 더욱 큰 마찰저항 감소효과를 나타내었다. 마찰 감소 진행 중의 높은 전단력에 기인하는 고분자의 분해는 고분자 농도가 낮은데에서 더욱두 드러지게 나타났으며 온도 효과의 연구로부터 poly(acrylamide)가 poly(ethylene oxide)보다 열적으로 안정함을 알수 있었다.

공급사슬의 구조가 복잡해지고 고객의 수요가 다양해지면서 공급사슬에서의 물류기능은 점점 중요시 되고 있다 지금까지의 생산자는 전체 물류의 $50\%$ 이상을 제 3자 물류 업체를 통하여 수행하였다 그러나 최근 대두되고 있는 제 4자 물류환경에서는 물류센터가 물류컨설팅기능까지 수행함으로써 더 효율적인 물류를 수행하는 것을 목표로 한다. 이러한 환경에서 공급사슬 내의 물류센터는 단순히 제품의 배송 및 보관, 조달 업무를 수행하는 단계로써의 역할이 아닌 독립적으로 이윤을 추구하는 기업의 형태로 존재하게 된다. 따라서 제 4자 물류환경에서의 물류센터는 제품의 다양한 특성 및 수요의 패턴에 따라 효율적인 재고정책 선택과정이 필요하다. 그러나 기존의 연구에서 제시하고 있는 재고정책을 현실에 적용하기에는 한계가 있다. 이에 본 연구에서는 제 4자 물류 환경에서의 물류센터 시스템 구조와 다양한 제품특성 및 물류환경을 고려한 재고정책 선택모델을 제시한다. 수치예제를 통해 제안한 모델의 타당성 및 제 4자 물류시스템의 기대효과를 제시한다.

The study is aiming to shed light on not only the influence of logistics output by choosing the third party logistics as the using of third party logistics has been increasing by the manufacturing firms also look over the effect between the factor of third party logistics' choosing and logistics performance in accordance with the changing of the logistics environment. As a result of the study, both service and fame factor among the third party logistics choosing factors have a significant impact on the logistics performance, furthermore the service factor of the logistics environment has an influence on the logistics performance by customer factor after measuring the control effect, and the fame factor has an influence on the logistics performance by both globaliztion and information system factor.

채권자대위권은 채권자가 자기의 채권을 보전하기 위하여 채무자에 속하는 권리를 행사할 수 있는 권리이다(민법제404조). 채무자의 권리는 채무자가 행사함이 원칙이나 채무자가 제3채무자에 대한 권리를 행사하지 아니함으로 채무자의 책임재산을 제대로 보전하지 않아 총채권자의 공동담보에 부족한 부분이 생길 때에는 채권자로 하여금 채무자의 권리를 행사하여 책임재산의 보전을 꾀할 수 있도록 할 필요가 있고, 이러한 목적을 위한 제도가 바로 채권자대위권제도이다. 그러나 채권자대위권제도는 채권자 취소권에 비해 상대적으로 주목받지 못하고 있는 것이 현실이다. 즉 실제와 현행민법 규정사이에 커다란 괴리가 존재하고 있고, 행사의 범위, 효과에 관한 규정을 두고 있지 않고 있다. 이는 전적으로 학설과 판례에 위임되어 있는 실정이므로 따라서 본 논문에서는 채권자대위권에 관한 문제점을 검토해보고, 정확한 명문규정이나 제도적 장치를 마련하는 제도의 취지 및 목적에 합당할 수 있도록 합리적인 방안을 제시하고자 한다.
