The problem of temperament is not much of importance in Philosophical discussion compared to subjects such as liqi and Xingli. However, temperament is of great importance in practical study theory. "The reason people study is because they want to change their temper." the scholars said. The theory of change in temperament in neo-Confucianism is pursued in two directions. The first is to purify the temperament in a clear state. The second is to overcome the bias of temperament and lead it to a state of the middle path. The former is the study that purifies the murky water and turn it to a clear state, as the bead in it is brilliantly revealed. The latter is the study of maintaining without bias toward the path of nature itself. While the ultimate purpose of temperament change is to realize bright nature intact without obstruction of temperament, it goes through two processes specifically. It is to maximize intellectual and practical ability and overcome bias in inclination and character. The purification of temperament and the realization of Zhong are in sync with the orientation of the theory of temperament change.

The area of design is the key which can create the generation's core values consistently influenced by the various media, throughout the rapid growth of technology and globalization. In the past, the design used to be defined as 'aesthetic', 'decorative', and 'satisfaction of the sensibility'. However, we believe it is time for a different value followed by the issue of user's different backgrounds and cultures. As the need arises, cross culture study has requested that we analyze how we understand the user's backgrounds and cultures. By doing so, it defines the user's needs like focus group interviews and methodology on process of product development or evaluation. Therefore the subject of this study is how the communication between two groups are affected by the difference between two cultures that centers on focus group interviews which has different consequence by diverse cultural backgrounds and personalities. Because personalities cannot be separated from cultural context, we have the compared group as a result of MBTI and establish practical methodology for proving the cultural factor which influenced to the difference of communication ways.

Objectives : This study investigate to identify the stability of temperament and personality characteristics of patients including Posttraumatic Stress Disorder (PTSD) patients. Methods : The number of subjects was 102, of which 33 were PTSD patients and 69 were non-PTSD patients. To demonstrate the change in individual temperament and personality characteristics, Temperament and Character Inventory (TCI) were administered repeatedly on the subjects. Repeated measures ANOVA and simple main effects analysis were conducted. Results : When analysed by dividing the subjects into PTSD groups and non-PTSD groups, the differences between the primary and secondary tests did not appear in the non-PTSD groups, but the differences between the primary and secondary tests were significant in Harm Avoidance (HA), Reward Dependence (RD), Self-Directedness (SD), Cooperativeness (C). In addition, it was noted that the time and group interaction effects of HA, RD, SD and C were significant, and that the main effects of time of HA, RD, SD and C were significant. Conclusions : This study is meaningful in that in the course of experience and recovery of traumatic events, we have clinically confirmed that changes in the temperament, known as stable variables, are possible.

This thesis aims to suggest probability of modern confrontation of Yulgok YiYi's thought. For this, find out the meaning of Li-Qi-Zhi-Miao(理氣之妙) and through the Qi-Fa-Li-Cheng-Yi-Tu(氣發理乘一途), and Li-Tong-Qi-Ju-Shou(理通 氣局說), Yin-Xim-Do-Xim-Shou(人心道心說), he creatively reveal the relation of Xin(心) Xing(性) Qing(情) Yi(意) continually. On one side he suggested the way of ideal man, on the other side he was showed adaptablity to the real world. So I think Yulgok had placed emphasis on the Zhongyong(中庸) and Yijing(周易), so he point out the meaning of ShiZhong (時中). Then he had high ideals practical Zhi-Zhonghe((致中和). So This paper is to find out his foundation of epistemology, and then to know It's modern meaning of methodology of moral Education's Implication on the relation of Xin(心) Xing(性) Qing(情) Yi(意). So We ca find out Ji(機) is very important the transition of Qi-Zhe(氣質).

The second-order rate constants for the nucleophilic substitution reactions of para-substituted benzyl nitrates with para-substituted anilines in acetonitrile were conductometrically determined. Hammett ${\rho}$x and ${\rho}$y values and Bronsted ${\beta}$ values were obtained from these kinetic data. The reactions of Benzyl nitrates with the series of anilines showed linear Hammett plots with negative slopes. For the change of substituents in the benzyl nitrates, nonlinear Hammett plots with a concave upwards curve were obtained. We applied the potential energy surface and the quantum mechanical models in order to examine the transition state variations caused by changes in substituents on the nucleophile and the substrate. The results showed that the reaction was proceeded via the $S_{N}2$-type reaction mechanism in which the extent of bond-formation was greatly changed depending on the property of the substituents in substrate.

Kinetic analysis was done to elucidate the reaction mechanism of purine nucleoside phosphorylase (PNP) in Saccharomyces cerevisiae. The binary complexes of PNP${\cdot}$phosphate and PNP${\cdot}$ribose 1-phosphate were involved in the reaction mechanism. The initial velocity and product inhibition studies demonstrated were consistent with the predominant mechanism of the reaction being an ordered bi, bi reaction. The phosphate bound to the enzyme first, followed by nucleoside and base were the first product to leave, followed by ribose 1-phosphate. The kinetically suggested mechanism of PNP in S. cerevisiae was in agreement with the results of protection studies against the inactivation of the enzyme by sulfhydryl reagents, p-chloromercuribenzoate (PCMB) and 5,5'-dithiobisnitrobenzoate (DTNB). PNP was protected by ribose 1-phosphate and phosphate, but not by nucleoside or base, supporting the reaction order of ordered bi, bi mechanism. PCMB or DTNB-inactivated PNP was totally reactivated by dithiothreitol (DTT) and the activity was returned to the level of 77% by 2-mercaptoethanol, indicating that inactivation was reversible. The kinetic behavior of the PCMB-inactivated enzyme had been changed with higher $K_m$ value of inosine and lower $V_m$, and was restored by DTT. Inactivation of enzyme by DTNB showed similar pattern of K sub(m) value with that by PCMB, but had not changed the $V_m$ value, significantly. Negative cooperativity was not found with PCMB or DTNB treated PNP at high concentration of phosphate.

The reaction rates of substituted quinolines (6-Clqui., qui.) with p-substituted benzoylchlorides $(p-CH_3,\;p-H,\;p-NO_2)$ have been measured by conductometry in acetonitrile, and the rate constants are determined at various temperatures (10, 15, 20, $25^{\circ}C$) and pressures (1, 200, 500, 1000 bar). From the values of rate constants, the activation parameters $(Ea,\;{\Delta}V^{\neq},\;{\Delta}H^{\neq},\;{\Delta}S^{\neq}, \;{\Delta}G^{\neq})$and the pressure dependence of Hammett ρ values were determined. The rate constants increased with increasing temperatures and pressures, and are further increased to introduction to the electron acceptor substituents in substrate $(p-NO_2)$ with quinoline. The activation volume and the activation entropy are all negative. And the Hammett p values are negative for nucleophile ${\rho}_X$ and positive for the substrate ${\rho}_Y$ over the pressure range studied. The results of kinetic studies for pressure and substituent show that these reactions proceed through a typical $S_N2$ reaction mechanism and "associative $S_N2$" favoring bond formation with increasing pressures.

T'oegye placed great emphasis on the cultivation of quiet-sitting. His idea of quiet-sitting, like Zhu Xi's, had various therapeutic effects as well. This can be highlighted as a real-life practice and a diverse application of the "abiding by Gyong" that he stressed; it is also associated with the treatment of physical diseases, composure in the mind, the benefits of reading, meditation in solitude, and many other areas. And We can easily infer that T'oegye would have set some premises before referring to Hualin Simbang. First, he would have been wary of quiet-sitting being the goal of cultivation: Too much obsession with and emphasis on Toinsul would actually obstruct the practice of "abiding by Gyong" and mislead one's effort for the "preservation and nourishment of the mind" and "reflection and examination." T'oegye would have probably used the physical and breathing exercises in Hualyin Simbang mainly as a reference to treat his physical illnesses. Also, his Toinsul would have been employed independently and partially as a sort of supplementary practice-without being used in parallel with quiet-sitting as one of the methods to achieve reverent seriousness.

The reaction rates of para-substituted benzoyl chlorides ($p-CH_3$, p-H, $p-NO_2$) with pyridine have been measured employing the conductometry method in acetonitrile. The pseudo first-order and second-order rate constants were determined at various pressures and temperatures. The activation parameters (${\Delta}V{\ddagger},\;{\Delta}{\beta}{\ddagger},\;{\Delta}H{\ddagger},\;{\Delta}S{\ddagger},\;{\Delta}G{\ddagger}$) and the Hammett ${\rho}$-values are determined from the values of rate constant. The values of ${\Delta}V{\ddagger},\;{\Delta}{\beta}{\ddagger}\;and\;{\Delta}S{\ddagger}$ are all negative. The Hammett ${\rho}$-values are positive for the substrate (${\rho}_Y$) over the given pressure range. The results of kinetic studies, for the pressure and substituent changes, show that these reactions are proceeded by a typical $SN_2$reaction mechanism and its bond formation is favored with elevating pressure.

Introduction：Test anxiety is a pervasive problem among high school students in Korea. While anxiety in test situations may actually facilitate the performance of some students, more often it is disruptive and leads to performance decrements. Over the past years, many child psychiatrists have become concerned with understanding the nature of test anxiety, but it is not clearly understood yet. In order to understand the nature of test anxiety, the relationship between test anxiety and depression, state anxiety, trait anxiety, temperament and family environment were examined. Methods：The Test Anxiety Inventory, Chidlren's Depression Inventory, State-Trait Anxiety Inventory, Temperamnet and Family Environment Scale Scale were administered to 576 high school students in Seoul. The relationships between test anxiety and other measures were tested using Pearson correlation coefficients and to test the causal relationship among the variables, regression analysis was performed. Results：The correlation coefficients between test anxiety and depression, state anxiety, trait anxiety, temperament and family environment scale were 0.42(p<0.01), 0.34(p<0.05), 0.38(p<0.05), 0.36(p<0.05) and -0.23(p<0.01), respectively. Regression analysis showed that only state and trait anxiety had direct causal relationship with test anxiety. Depression, temperament and family environment were indirecly related with test anxiety. Conclusions：This study indicates that the level of state and trait anxiety are directly related with test anxiety, and other variables such as temperament, family environment and depression are indirectly related with test anxiety. Thus, in order to develop the effective methods for treatment, these psychopathological characteristics should be kept in mind and the most important factors are the levels of state and trait anxiety.
