Objectives: The aim of this experimental study is to investigate effects of Dolichoris Semen, Terminaliae Fructus and Bojanggunbi-tangon the anti-cathartic action of mice and guinea pigs to develop effective herbal medicine and prescription to cure diarrhea early and to prevent side effect of chronic diarrhea. Methods: To compare effects of Dolichoris Semen, Terminaliae Fructus and Bojanggunbi-tangon the anti-cathartic action of mice and guinea pigs, we evaluated the actions on isolated gastrointestinal smooth muscles. on the transportability of small and large intestines, onthe neostigmine-induced transportability of small intestine and on diarrhea induced by castor oil, pilocarpine, barium chloride. Results: (1) Dolichoris Semen, Terminaliae Fructus and Bojanggunbi-tang showed the strong alleviation on the contraction of mice's isolated gastrointestinal smooth muscles induced by acetylcholine chloride and barium chloride. while Terminaliae Fructus, strong, Bojanggunbi-tang, intermediate and Dolichoris Semenshowed the minor alleviation on the contraction of guinea pigs' isolated gastrointestinal smooth muscles induced by acetylcholine chloride and histamine. All effects depended on the density in each medicine. (2) The tranbportability of small intestine was contrained in the groups controlled by 600 mg/kg of Dolichoris Semen, Terminaliae Fructus and Bojanggunbi-tang, and 200 mg/kg of D olichoris Semen and Terminaliae Fructus. However, the enhancement of neostigmine-induced transportability of small intestine was constrained only in the groups controlled by 600 mg/kg of Dolichoris Semen, Terminaliae Fructus and Boianggunbi-tang. (3) The transportability of large intestine was constrained by Dolichoris Semen and Bojanggunbi-tang. They showed substantial results. which depended on the amount of each medicine. (4) Terminaliae Fructus showed substantial anti-cathartic effects on diarrhea induced by caster oil in both groups controlled by 200 and 600 mg/kg of it. However, Bojanggunbi-tangshowed the effects only in the group controlled by 600 mg/kg. in diarrhea induced by pilocarpine, the groups controlled by 600 mg/kg or Terminaliae Fructus and 200 and 600 mg/kg of Boianggnbi-tangshowed substantial results. In diarrhea induced by barium chloride. the groups controlled by 200 and 600 mg/kg of Terminaliae Fructus and 600 mg/kg of Boianggunbi-tangshowed substantial results in anti-cathartic effects. Conclusions: These results show that Terminaliae Fructus is more effective on the contraction of mice and guinea pigs' isolated gastrointestinal smooth muscles, Dolichoris Semen is more effective on the transportability of small intestine, Dolichoris Semen and Bojanggunbi-tang are more effective on the transportability of large intestine.

In early Josun(朝鮮) era, the scholars, genteels, and high officials in Josun dynasty paid attention to Sijo(時調) who hoped Josun society would share Confucian values. Sijo poems written by them are based upon Confucian ideology, giving an opportunity to its members to make sure their homogeneity and helping Josun dynasty sustain its regime. Gyongichega(景幾體歌) has, however, already failed to be an appropriate genre to do these functions. Nevertheless, in the late Josun dynasty when there were agitation in class hieracy, development of currency economics, maldistribution of wealth, and pursuit of enjoyment, obscene poems turned out. Consequently these songs contributed to encroaching and eventually destroying the Josun dynasty. The question that who are in charge of creating and enjoying Sasulsijo(辭說時調) cannot be answered by approaching it in the social class point of view. The range of the maker or the reader of Sasulsijo in the late Josun dynasty was much more extensive than that in the early times. Not only aristocracy or the middle society but even some of the lower class may have made and enjoyed those songs. In the meantime, it is singer-songwriters whom Park, Hyogwan blamed for their profiteering abuse of obscenity that is supposed to have been mainly reponsible for the creation of those songs. Siga is a double-edged art in its essence--the good and the bad. The lewd songs were, in the early Josun, strictly controlled but in the late Josun dynasty, were thriving due to social changes. In this context, songs based on Confucian ideology as well as the ones focused on sexual love became decayed along with the collapse of the Josun dynasty. Even though, in the light of the history of Siga, those two types of Siga are underestimated in its artistic value, they have very special social historical meaning in doing positive and negative functions for existence and destroy of the Josun dynasty.

Illustration has been used as a means of human communication since the primitive age. And now it has become a way to express impliedly either the fragmentary or the psychological side of our life. Like it has been said in peter knock's Illustration magazine, an artist said "it was the best article ever read." Illustrator's task is to abstract and practically describe not our daily life, but every moment of the perception an object, whether it is define or indefine. It can inspire stronger perception than any other elegant language. Addition to that the practical use of illustration is increasing ever day. The target has now become various such as man, nature, art, science and so on. Therefore, at this point what illustration requires is creation, new and striking idea. It is because in order to get in to the general's living in the complicate and various society, it must show unique images and appearance. Therefore, now the illustration should induce the work which is based on synetics thoughts, not simple improving skill. Now we must restrain futional and diagrammatic illustration education and be able to thik of free and abundant characteristics. It will eventually help students to feel the value of human life and free themselves from the reality of present education which is getting machinized and instrumentalized.entalized.

An immunohistochemical study was performed to demonstrate comparative antigenicity of each body structure of the liver fluke, Clonorchis sinensis, such as the digestive tract, reproductive organs, excretory system, tegument and suckers. Indirect immunoperoxidase technique was applied, rising formalin-fixed and paraffin-embedded sections of C. sinensis as the antigen. Pooled cat sera obtained 10 weeks after an experimental infection with C. sinensis and peroxidase-conjugated goat anti-cat IgG were used as the primary and secondary antibodies, respectively. The intensity of immunohistochemical stain was very sensitive upon the titers of the primary and secondary antibodies, and their optimum dilutions were found to be 1:1,000∼1:2,000 and 1:1,000, respectively. The intestinal epithelial cells, intestinal content and excretory bladder showed strong positive coloring reactions even at lower titer (1 : 2,000) of the primary antibody, whereas the uterine wall and eggs, vitelline glands, and male reproductive organs showed only weak positive reactions despite an increase in the antibody titer (1:1,000). On the other hand, the suckers, tegument, subtegumental cells and other parenchyme portions did not reveal any positive immunoperoxidase reaction at the same antibody titers. From the above results, it is highly suggested that the most potent antigenicity of C. sinensis occur from their excretory-secretory substances originated from the digestive and excretory organs.

This study, centering on public enterprises, has been conducted from 4 different perspectives such as grasping the effects that the factor precedent of the multi-rater feedback affects on the usefulness of evaluation and the effects that the usefulness of evaluation affects on the organizational achievement, checking on whether there is any discrepancy among the effects affecting on the usefulness of evaluation in accordance with the degree of advance training on the evaluation system, and being what kind of effects the usefulness of valuation that the appraised eventually understand affects on the organizational achievement. As result of the study, the factor precedent that are confidence of the appraisers and the support from CEO reasonably affected on the usefulness of evaluation, but the standard referred to evaluation was not reasonable. It became resultantly clear that the confidence of the appraisers held the effect of control from the verification of whether there is the effect of control between the factor precedent and the usefulness of evaluation in accordance with the degree of advance training. However, it turned out that the standard referred to evaluation and the support from CEO held no effect of control. As result, It was possible to confirm that the usefulness of evaluation in this study affects directly or indirectly to the organizational achievement such as organizational immersion, job satisfaction, self development opportunity, and organizational revitalization as influenced by the prior factors, and the advance training was partially effective on the adjusting effect.
