Defocused CO_2 laser beam irradiation strengthening of 60kgf/㎟ grade steel sheet was investigated to obtain the tensile strength similar to that of fully penetrated one by the focused beam. The melted line width by the defocused beam was 3∼4 times larger compared to that of the focused beam. However, the increase of tensile strength with 1 line irradiation by the defocused beam was similar to that of 2∼3 lines by the focused beam. The increase(37.6%) of bending strength with 1 line by the defocused beam was higher than the increase(12.9%) of tensile strength. Also, the effect of cooling gas to strengthening was observed.

This research is about success and role conflict in which through the use of questionnaires success perception, success attributes, role conflicts in the success pursuit process, and coping methods have been surveyed. Result is summarized as following: above all, the meaning of success appeared differently to men and women. Standards of mens success are mainly occupation, economic power and ability, on the other hand, womens success is happy family. In the items to measure the degree of success, general success evaluation scores are high, however, the sex difference is not appeared. On the other side, as a result of the survey to find out how success perception relates to personality of the individual person, androgynous trait is the most important personality characteristic in all aspects of success. And as male trait is important in occupation of success perception, female is in family and interpersonal relationship. Attribution of the success cause appeared in order of ability, effort, interest, and aptitude consistently with the general success groups attribution pattern. Analysis of conflicts meeting in the process of success pursuit, cause of conflicts pointed out to be at work is job dissatisfaction, problem of parelling work and family at the same time, conflict with boss, and differences in values at the job. And in family the cause is children, economics, family health, conflicts with in-laws and there to with spouse. In the result, there appears to be no difference in work or family in coping methods of these conflict phenomenon. However, in the group which actively tries to find coping method showed sex differences. There appeared more response in women as to men to look for where can give out help. Where as in the inactive coping group, high response in men appeared to stick with the methods of previous problem solving. These results show necessity of not only women counseling centering those women who need help, but also men counseling for those men who do not seem to recognize the apparent necessity of counseling. However, in order to get the counseling effect, it needs an approach in where clients traits are carefully considered. In a time context where success is emphasized, it is earnestly needed to recognize various problems of success, to understand those conflict phenomena produced in the success process, and to seek coping methods for these. Accordingly, through counseling procedures and vast amount of knowledge about success and its various problems should be reflected in counseling. Therefore to seek ways and means to help and individual for further successful adjustment.

The present study is to examine the counselor verbal response mode. The first purpose of the present study is to examine the difference between the novice counselor and the experienced. In counselor verbal response mode that could affect counseling outcome. The second purpose is to examine the assumption that there would be difference in counselor 's response mode between successfully terminated and drop-out cases. For the purposes, the data were collected from eight actual counseling cases: four from two novice counselors who had less one year experience and four from two experienced who had more than ten year experience. And two drop-out cases were included out of four cases of the novice counselors. All the cases were audio taped and then written out into verbatim and the verbatim were analyzed by three objective raters who were graduate students. All the sessions were third or fourth session. The results of this study are summarized as follows: First, the most frequently used counselor verbal responses were: "closed question" and "open question" in novice cases; "interpretation" and "confrontation" in experienced cases. Second, significant difference was found in counselor response mode between the novice and experienced: "approval/reassurance", "closed question" and "reflection" were significantly frequent in novice comparing to the experienced; "open question", "restatement", "interpretation" and "confrontation" were significantly frequent in the experienced comparing to novice. Third, signigicant difference was found between successfully terminated cases and drop-out cases: "closed question" and "interpretation" were more used in terminated; "open question ', "restatement", "reflection" and "confrontation" were more in drop-out cases. In spite of restricted small number of cases the results of this study could be used in counselor education and training.

A matallo-organic solution was stamped from the channels of a polymer stamp onto a glass. The precursor solution consisted of copper 2-ethylhexanonate, 2-ethoxyethanol as a solvent and ethylene glycol to improve surface energies. The solution was deposited to the polymer stamp by spin coater. After drying the solution in channels of the stamp, the dried ink was transferred to a substrate by debonding from channels. The process parameters such as solution compositions and pressing methods were discussed experimentally to form a copper pattern whose morphology was excellent.

In order to investigate the relationship between personality factors and parents-child bonding patterns influencing the development of panic disorder, we in Gu-Ro hospital studied 39 patients with panic disorder with 16 Personality Factor Questionnaire(16PF) and Parental Bonding Instrument. The results were as follows : 1) Higher overprotection scores and lower caring scores were noted in PBI. In 16PF higher desurgency, shyness, praxernia, guilt-proneness, liberalism and anxiety were observed. 2) Maternal overprotection was positively correlated with dominance, shyness, conservatism and maternal caring was positively correlated with dominance, high superego, suspiciousness, shrewdness. Paternal overprotection was positively correlated with self-control. Paternal caring was positively correlated with high intelligence, stableness and was negatively correlated with anxiety. Paternal overprotection and caring were negatively correlated with each other. Maternal overprotection was positively correlated with Paternal overprotection. 3) Groups classified by parental bonding pattern indicated that affectionless control(group Ⅳ) was correlated with more negative aspects of personality factors. These findings suggest than panic disorder patients have highly overprotection and low caring parents and that they have negative aspects of personality factors. Such negative aspects of personality factors seem to be related with their negative parent-child bonding patterns.

This study is an attempt to survey Korean adolescents' conceptions of adults by the method of word association tests. First and second grade students of eight schools in the City of Seoul(boys and girls middle and high schools) were selected as the subjects. The total number of subjects was 1,053; 547 were middle school students and 506 were high school students. The subjects were asked to write five words that they associate when they hear the word, "adult". The total number of associated words was 4,895; 2,512 in the middle schools, and 2,383 in the high schools. The analysis of the study was carried out in two ways: firstly, for these associated words frequencies were calculated for each grade level and by sex; and secondly, these words were classified into eight separate categories according to their meaning; (1) privileged adult, (2) matured adult, (3) socialized adult, (4) conservative adult, (5) misunderstandable adult, (6) dislikable adult, (7) physically well-developed adult, and (8) symbolic adult.
