  • 사람에게 행동의 개인차가 있듯이 rat이나 mouse에 있어서도 행동의 차이를 발견할 수 있다. Rat의 행동성향에 따른 (1)학습 및 기억 능력의 차이, (2)기억과 해마의 관계, (3)치매유발단백질의 하나로 알려진 아밀로이드 베타($A{\beta}$ )및 수종의 항 치매 약물효과를 알아보는 것이 본 실험의 목적이다. Rat의 행동관찰을 통해 두 가지 행동패턴을 관찰할 수 있었는데, 이러한 rat의 행동 특성은 심리학자 Jung이 심리유형으로 설명하고 있는 extraversion, introversion의 행동성향과 유사할 것이라는 가정 하에 실험을 계획, 실시하였다. Rat에 water maze test를 실시하여 공간 기억의 단기, 장기 기억을 분석하였는데 그 결과 두 가지 행동 성향을 가진 rat은 서로 다른 학습 및 기억 능력의 특성을 보였다. 즉, extraversion은 단기 기억의 향상을 보인 반면에, introversion은 장기 기억의 향상을 보였다. Rat을 대상으로 water maze test 외에 Y-maze, passive avoidance test를 실시하여 공간 기억(spatial memory), 작동 기억(working memory), passive avoidance memory, 그리고 단기, 장기 기억의 관계를 종합적으로 분석해 보았다. 그 결과 두 가지 행동성향에 따라 서로 영향을 미치는 기억의 종류 및 관계에 차이가 있음을 발견할 수 있었다. 또한 두 가지 행동성향을 가진 rat에 약물을 투여했을 때, 서로 다른 약물 효과를 보였으며, $A{\beta}$ 를 주입했을 때, 기억(memory) 및 해마(hippocampus) 세포 사멸(cell death)에 서로 상반된 결과를 보여주었다. 이러한 연구 결과는 개체의 행동성향에 따라 학습 및 기억의 효과가 다를 수 있음을 보여주는 결과라 할 수 있고, 개인의 적성과 소질의 인식 및 개발의 중요성에 시사하는 바가 크다. 또한 개개인의 행동과 학습 및 기억 능력의 차이를 두뇌과학적으로 이해하여, 두뇌의 장점은 살리고 단점을 보완할 수 있는 이론적 토대를 세우는데 이러한 동물실험이 그 기초를 제공해 줄 수 있을 것이다. 또한 행동성향 및 기억의 종류에 따른 약물효과의 차이는 기억과 관련된 질병인 알츠하이머 환자에 있어 개개인에게 맞는 적절한 특징적인 치료약물이 존재할 것이라는 가능성을 제공해줄 뿐만 아니라 학습과 기억력 증진 효과를 기대해 볼 수 있을 것이라고 생각된다.

  • This study was carried out to compare pH and chemical properties of dew in three forest stands(Mt. Nam-Seoul, Shingal-Yongin, Hangdong-Pyungchang)from May, 1998 to September, 1999. The results of this study were as follows; The acidity of dew in Seoul, which has a metropolitan environment, measured pH5.57 $\pm$ 0.41. The highest acidity was measured in Yongin(pH5.50 $\pm$ 0.96), while pH in Pyungchang was 6.36 $\pm$ 0.57. Ion concentration in Pyungchang was lower than in other two regions, with a similar tendency of seasonal cation changes to those in Seoul and Yongin. Anion changes in Pyungchang, however, was inconsistent with those in other two regions. Although analyses of correlation coefficients showed that there was no significant correlation between overall ion concentrations and pH of dew, there was highly significant correlations between some cations and anions in Seoul and Yon gin, leading a suggestion that those ions were coupled from one source.

  • This study examined the role of self-construals in marital satisfaction among men and women, and explored how independent and interdependent self-construals contribute to or undermine marital satisfaction. Data were drawn from a self-administered questionnaire study in which 489 married people(aged 25-75) residing in Seoul participated. Path analyses were conducted using Structural Equation Modeling Program, and a goodness of fit of the proposed path model was evaluated. As expected, the positive impact of independent self-construal on marital satisfaction was mediated by self-esteem and clarity of communication, and that of interdependent self-construal on marital satisfaction was mediated by psychological stability and a sense of relational well-being. The direct effects of these two types of self-construal on marital satisfaction were opposite. As predicted, independent self-construal decreased marital satisfaction, whereas interdependent self-construal increased it. All of the direct and indirect effects of independent and interdependent self-construals on marital satisfaction were statistically significant, except the indirect effect of interdependent self-construal as mediated by psychological stability. The goodness of fit indexes of the path model indicated that the model was acceptable. However, the results of separate path analyses for men and women showed that some of the effects of self-construals on marital satisfaction differed by gender. Based on these results, implications for clinical social work practice were discussed.

  • We examine the information transmission between the business survey index(BSI) based on the returns data offered by Federation of Korean Industries and KOSPI Index based on the returns data offered by Korea Bank. The data includes monthly return data from January 1998 to September 2015. The results of the analysis are as follows. Firstly, results of Granger Causality test suggests the existence of mutual causality KOSPI Index precede and have explanatory power BSI. Secondly, the results of impulse response function suggest that BSI Index show immediate response to KOSPI Index and are influenced by till time 4 From time 2 the impact gradually disappears. Also KOSPI Index show immediate response to BSI and are influenced by till time 4 From time 2 the impact gradually disappears. Lastly, the variance decomposition analysis showed a high influence of the KOSPI Index on the BSI and significant influence of the BSI on the KOSPI Index. This implies that returns on the KOSPI Index have a significant influence over returns on the BSI. The study is a further extension of existing studies on information transmission mechanism between the BSI and KOSPI. Finally, our results can be used as a guide by the Korea Bank and Republic of Korea and as well as Federation of Korean Industries.

  • In this study, the physicochemical characteristics of imported whole sesame oil (WS; WS1, WS2), imported sesame powder oil (SP; SP1, SP2), sesame oil mixed with imported whole sesame and sesame powder (WSP; WSP1, WSP2) were analyzed and their quality characteristics were compared according to the imported raw material type. $L^*$ and $b^*$ values of WS1 were the lowest and the browning index was significantly high. WS2 showed contrasting results. The redness of sesame oil was high due to its high acid value. The correlation value showed a low acid value as the content of saturated fatty acid was high. SP showed low values for antioxidant property and overall preference. The overall preference score of sensory evaluation showed the highest positive correlation with the score, suggesting that SP lacked the unique fragrance. Therefore, SP lacked the specific aroma and antioxidant property.

  • The Trust Act, which was first enacted back in 1961, was fully revised on 25. July 2011 and enacted on 26. July 2012. The Act is a fundamental norm governing trust relation, so the revision was expected to play an important role to promote trust institutions. However many problems were also revealed after the enactment. The Act has already inherent limitations because the previous discussions were not enough and the amendment process was not meticulously reviewed. Now it is needed to consider the comprehensive amendment of the Act reflecting detailed legal doctrines developed hitherto by the courts and the legal academia. This paper aims to call for the revision of the Act and to propose the ways and the grounds for revision. The purpose of the revision is to rectify obvious errors on several provisions, to minimize legal uncertainty by presenting detailed rules on many issues, to enhance the coherence and consistency between the rules along with supplementing the relevant laws, and to strike a proper balance between the parties.

  • Soils originated from limestone, located at the southern part of Kangwon province and Jecheon, Danyang of Chungbuk province are mainly composed of fine texture, have different properties from soils originated from granite and granite gneiss, especially for water movement. This study was conducted for making PTF(Pedo-Transfer Function) for Kfs(field saturaton hydraulic conductivity) estimation, and for investigating the relation between soil particle distribution and the infiltration and percolation rate in soils originated from limestone. Soils used for the experiment were 6 soils of Gwarim, Mosan, Jangseong, Maji, Anmi and Pyongan series. Infiltration and percolation rate for the soil were measured by a disc tension infiltrometer and a Guelph permeameter, respectively. The particle size distribution and organic matter content of the soils were analyzed. Kfs was not related with sand, silt, clay, and organic mattrer (OM) content because of forest soils which contained high gravel, pebble, and cobble content, and O layer with high OM content. After Mosan soil series and O layer of Gwarim series were excluded for the data analysis, Kfs was explained as a linear function with sand and clay content and a exponential function with OM content. As a result, the PTF equation was obtained as Kfs=-4.20558+0.479706*(S)+0.023187*exp(1.829*OM) ($R^2=0.6558^{*}$).

  • Researchers in channel dyads have devoted much attention to relationship between interdependence (i.e. interdependence enymmetry and total interdependence) and conflict that promote channel performance. In social science, in spite of the inconsistent results in marketing practice, there are two contradictory theories explain the relationship between interdependence and conflict - bilateral deterrence theory and conflict spiral theory. The authors apply these theories to co-marketing alliance situation in terms that this relationship is also incorporated both company's dependence, either from one company's perspective or each partner about its respective dependence. Using survey data and archival data from 181 companies enlisted in a telecommunication membership program, the authors find out the relationship between interdependence and conflict as well as investigate the antecedents of interdependence - transaction age, transaction frequency, the numbers of alliance partner, and co-marketing alliance specific assets according to previous researches. Using PLS analysis, the authors demonstrate that, with increasing total interdependence in a telecommunication membership program, two co-marketing partners' conflict level is increased in accord with the author's conflict spiral theory predictions. As expected, higher interdependence asymmetry has negative value to level of conflict even though this result is not statistically significant. Other findings can be summarized as follows. In the perspective of telecommunication company, transaction age, transaction frequency, and co-marketing alliance specific assets have influence on its dependence on a partner as independent variables. To the contrary, in a partner's perspective, transaction frequency, co-marketing alliance specific assets and the numbers of alliance partner have significantly impact on its dependence on a telecommunication company. In direct effect analysis, it is shown that transaction age, frequency and co-marketing alliance specific assets have direct influence on conflict. This results suggest that it is more useful for a telecommunication company to select a co-marketing partner which is frequently used by customers and earned high rates of mileage. In addition, the results show that dependence of a telecommunication company on a co-marketing partner is more significantly effected to co-marketing alliance conflict than partner's one. It provide an effective conflict management strategy to a telecommunication company for controling customer's usage rate or having the co-marketing partner deposit high level of alliance specific investment (i.e. mileage). To a co-marketing partner of telecommunication company, it is required control the percentage of co-marketing sales in total sales revenue or seek various co-marketing partners in order for co-marketing conflict management. The research implications, limitation and future research of these results are discussed.

  • Film was invented by human's desire to copy the real world, starting in the late 19th century. Since the birth of cinema, It was given mission to replay of the real world. On the other hand, cinema was regarded as a fictitious art form. Although the invention of film brought about experience of replaying of the real world it has been reproduced reality with creative story. And it also has been represent reality with sense of reality. Cinema's way of reproduction implied conflicting concept of mimesis. Triple Mimesis of Paul Ricoeur was an idea expanded into an analytical concept from that simple concept of mimesis. The purpose of this study was to examine the prefiguration of shown behavior in Columbine High School massacre based on Triple Mimesis of Paul Ricoeur. It also was to examine a form of representation on cinema which is 'Elephant' and studied how the form of representation on Elephant could interpret by audience. It could be define the relationship between reality and reproduction through this esthetic study. This paper attempted to build the method communication between the originator and audience with a whole analytic process of time and story on the cinematic representation.

  • Action games exhibit all the specific constellation of masochism, such as disavowal, suspense, waiting, fetishism, and fantasy. These characteristics of action games can be analyzed with respect to masochism. This study conducted an analysis excluding sadism as much as possible, as sadism is a result of etiological misconception as opposed to masochism. However, comparative analysis is included in the study so that action games are not seen as demonstrating sadism. Games create a space for virtual interaction for main agents by connecting gamer-existence and game-character in the framework of a contract. The interaction of visual tactility within this space creates a system of difference in pleasure. Masochism enables one to attain pleasure in a world created himself or herself using fetishism in contractual relationships such as the ones exhibited in games. This shows that action games and masochism are mutually related. This paper analyzed the ontology of action games using actual examples of action games. The paper concluded that action games lead to the fulfillment of masochistic pleasure.
