The recycling rate of recovered paper in Korea is the highest in the world, 92%, but remanufacturing yield is low due to the extremely poor quality of the paper. The poor quality, in turn, influences to the reject amount in deinking process. To increase the yield of old newspaper recycling process, hydrophobic degree of inorganic pigments of deinking stock must be reduced. To determine the hydrophobicity, Pitch Potential Deposit Tester (PDT) was newly designed and applied with respect to the SB latex property of various quality used in Korea; its hydrophobic degree according to Tg, gel content, charge and particle size of latex and optimum designing condition of SB latex. And below are the conclusions

본 연구는 최근 진로이론에서 주목받고 있는 사회인지 진로이론에 주목하고 전문대학 신입생들의 개인적 변인, 인지적 변인 및 환경맥락적 변인들을 구조화한 연구모형으로 구성하여 전문대학 신입생들의 대학적응 만족도를 높임으로써 우리 사회에 건전한 전문직업인 양성에 도움을 주고자 한 것이다. 이를 위해 J대학 학생상담센터에서 대학 포털을 활용하여 조사한 총 8개 학부 30개 학과의 신입생 2,212명의 자료를 활용하여 단순회귀분석, 다중회귀분석, 위계적 조절회귀분석, 3단계 매개회귀분석을 실시하였다. 분석결과 신입생들의 개인적 변인 및 인지적 변인인 자존감, 효능감, 성취동기는 각각 대학생활 기대수준에 긍정적인 영향을 미치며, 대학생활 기대수준은 대학적응 만족도를 높이는데 상당한 기여를 하는 것으로 나타났다. 한편 OT 만족도 또한 대학생활 기대수준을 높이는 중요한 요인이며, 대학생활 기대수준은 신입생들의 개인차원 변수들과 대학적응 만족도 간에서 만족도를 높이는 중요한 요인임을 확인하였다. 연구결과 신입생들이 입학한 후 1~3주 기간에 각 학과들과 대학수준의 자존감, 성취동기 및 효능감을 높일 수 있는 교수법과 다양한 비교과과정 프로그램 참여가 필요함을 알 수 있었다. 또한 신입생들의 오리엔테이션 프로그램 점검과 함께 대학에 대한 기대수준이 어떠한지 정확하게 측정하고 신입생들의 기대에 일치할 수 있는 다양한 노력이 필요함을 알 수 있었다. This study aimed to enhance new college students satisfaction with their adaptation to a college, and therefore, contribute to sound and professional training in our society by focusing on social cognitive career theory which has been recently highlighted and organizing individual, cognitive and environmental contextual variables into a structured research model. To this end, it conducted simple regression, multiple regression, hierarchical moderated regression analysis and three steps of mediating regression analysis, by using the data of 2,212 new college students enrolled in 30 majors of a total of 8 departments, who were examined by the students counseling center through the college portal in J College. The findings showed that new students self-esteem and self-efficacy and achievement motivation, which belong to individual and cognitive variables, had positive effects on their expectations for campus life which, in turn, made significant contributions to the enhancement of satisfaction with adaption to the college. Meanwhile, their satisfaction with OT was also an important factor for increasing their expectations for campus life which, in turn, was important factor for increasing individual variables and satisfaction with adaptation to the college. From the results of this study, it could be found that it would be necessary for new students to participate in a variety of extra-curricular programs and there should be teaching methods for enhancing their self-esteem, self-efficacy and achievement motivation in each major of the college for one-three weeks after they entered the college. In addition, it was also confirmed that various efforts to meet expectations of new students were required along with a check of orientation program for them as well as an exact measurement of their expectations for the college.

For investigating a disease specific psychological mechanism in various dermatological disorders, we tried to explore the difference in correlation among stress perception, locus of control as a coping strategy, depressive symptoms and pruritic symptoms in the patients with psychological pruritis and chronic urticaria. The subjects were composed of 32 patients with psychol-ogical pruritis and 67 patients with chronic urticaria(subject group), and 25 patients with organic pruritis and 59 patient with major depression(control group). Global assesment of recent stress scale(GARS), I-E locus of control scale, Beck Depression Inventory(BDI) and medical college of wisconsin center pain follow up questionnaire were used for assesement. The results were as follows: 1) There were a significant positive correlation between stress perception and depressive symptom in patients with psychological pruritis, chronic urticaria, and major depression but not hi organic pruritis. 2) In relationship between locus of control and depressive symptom, patients with psychological pruritis, organic pruritis, and major depression except chronic ruticaria showed a significant negative correlation. 3) For intensity and pattern of pruritis, there were positive relations with depressive symptom and stress perception only in patients with chronic urticaria. Above results indicate that stress perception and locus of contorl may play a significant role in the formation of psychological and dermatological symptoms in psychological pruitis and chronic urticaria. But the mechanisms of these processes are different in either disorder.

Synthetic method of a new benzoylphenylurea insecticide, DBI-3204 [1-(2,6-Difluorobenzoyl)-3-(3,5-bistrifluoromethyl-2-chlorophenyl) urea] was established for manufactural production; 2,6-Difluorobenzoylisocyanate was synthesized by the reaction of 2,6-difluorobenzamide with oxalylchloride in 95% yields, the reaction of 3,5-bis(trifluoromethyl)aniline with N-chlorosuccinimde gave 3,5-bis(trifluoromethyl)-2-chloroaniline in 92% yields, and DBI-3204 was got from 2,6-difluorobenzoylisocyanate and 3,5-bis(trifluoromethyl)-2-chloroaniline in 90% yields. All the process was simplified by using the same reaction solvent, carbontetrachloride.
