2, 6-Disubstituted-3-pyridazinones were synthesized from the reaction of trichloroethylideneacetone with substituted phenylhydrazines. From the reaction of trichloroethylideneacetone with ο-nitrophenylhydrazine, pyridazinone derivative was not obtained, but ${\gamma},{\gamma}$-dichloro-${\gamma}$-(o-nitrophenylhydrazino)-ethylideneacetone was obtained in 24% yield.

We define Fourier-Yeh-Feynman transform and convolution product on the Yeh-Wiener space, and establish the existence of Fourier-Yeh-Feynman transform and convolution product for functionals in a Banach algebra $\mathcal{S}(Q)$. Also we obtain Parseval's relation for those functionals.

In this paper, we prove that if $T{\in}L$(X) is a generalized scalar operator then Ker $T^p$ is the quasi-nilpotent part of T for some positive integer $p{\in}{\mathbb{N}}$. Moreover, we prove that a generalized scalar operator with finite spectrum is algebraic. In particular, a quasi-nilpotent generalized scalar operator is nilpotent.

액체구조의 천이상태 이론을 알칼리토금속 염화물에 적용시켜서 상태합을 유도하였다. 이 상태합으로부터 $SrCl_2$와 $BaCl_2$의 증기압, 몰부피, 엔트로피등의 열역학적 성질을 계산하여 실험치와 비교하였으며, 천이상태 이론이 용융염에도 잘 적용된다는 결론을 얻었다.

This study aimed to investigate the potential of Art Therapy to be part of Liberal Arts programs for university students. The study is based on the examination of the effect after the program. The program was combined with Art Therapy theory and with a practical part for students to have a psychological understanding of self development(ego-identity, self-esteem and interpersonal relationship). The subjects were 38 students who were registered in the Art Therapy course at N university. It was a two hour-course and was offered every week. The first 40 minutes of the class were used for explaining Art Therapy theory, and the last 80 minutes were given for practice. To analyze the effect of the program, the index of ego-identity, the index of self-esteem and the index of interpersonal relationship were used. Frequency, percentage and standard deviation were calculated with SPSS 12.0, and a paired t-test was followed. According to the results, this art therapy program has an effect on the subjectivity and future-confidence of students, which includes the sub-categories of self-identity. However, there was no effect found in the category of self-esteem. Comprehension, which is under the interpersonal relationships category, showed statistically meaningful differences after the program was done. Based on this study, it was revealed that Art Therapy as a part of the Liberal Arts programs, which incorporates a large number of students, can have a similar effect on people compared to the Group Art Therapy, which incorporates a relatively smaller number of people.

The Quality of physical therapy school system has conflicts between physical therpist, and reduces the opportunity of seguential education. So this study was investigated in order to made concrete the problems of educational duality, set up the direction of the school system's improvement, as like the four-year system and recognized the necessity. The curriculums of 13 colleges and 5 universities was analyzed. The curriculum analysis was made up the comparison and the analysis by a liberal arts point, a major point, a clinical practice point, total opening subjects, and so on. The analyzing results were as follows. 1. The average rates of a liberal arts vs. a major opening point are 17:83 in college, and are 27:73 in university. 2. It is a serious problem that college are lower than university in a liberal arts. The best method that can solve it is lengthen the number of school years. 3. There is no difference between college and university in a major subject. Rather college has the more subject's numbers than university. 4. There is no difference between college and university in a clinical practice. Above results suggests that there is not different between college and university in a major subject except for a liberal arts point. It is proper that one should be unificate the curriculum according to the sameness between a state examination and a license. Therefore, it is necessary for graduates from college that provides the opportunity of proceeding to a higher school, demands the seguential system of study cultivating and producing a bachelor, and requires the continual education in a clinical field, a bachelor admitting system of continual education, and clinical therapist's qualification. The present physical therapy educational systems should be unificated because of many right reasons. On the other hand, the follw-up study that improving the school system about the four-years and the more physical therapy should be continue from the viewpoint of education.

Computer-related OA lectures at the university mainly deal with the creation of word processing documents and presentations and spreadsheet documents. To use most of the course evaluation at the university will be evaluated by the subjective judgment about the satisfaction and the skills assessment of students. In this paper, we take a lecture given at the university of OA before and after the university students to self-diagnosis is to propose an survey. In addition, we would like to analyze more objectively the degree of use computer-related OA and the degree of improvement of computer skills by the proposed objective survey evaluate to students compare with students have acquired scores during the semester.

Generally it is not easy task whether the stable systems governed by nonlinear ordinary differential equations are asymptotically stable or not. This problem often appears in studying a collision and avoidance control problem based on the stability theory. In this paper we devoted to finding conditions that the stable system obtained from the collision and avoidance control problem is asymptotically stable.
