  • Barrier ribs in the color plasma display panel(PDP) function to maintain the discharge space between to glass plates as well as to prevent optical crosstalk. Patterning of barrier ribs is one of unique processes for making PDP. In this work photosensitive barrier rib pastes were prepared by incorporating binder polymer, solvent, functional monomers photoinitiator, mid barrier rib powder. Study on the function of materials for the barrier rib paste were undertaken. After optimization of paste formulation, both photolithographic and transparent soft molding method resulted in fine pattern of barrier ribs with high aspect ratio.

  • A new PDP barrier rib formation technique was investigated utilizing transparent soft maid made of silicon resin. Transparent soft mold was fabricated by pouring a silicone resin into the base mold made with photosensitive glass. The photosensitive barrier rib paste was coated on the glass substrate and dried in a 90 $^{\circ}C$ convection oven for 20min. The transparent soft mold was pressed on top of the semi-dry barrier rib layer and then irradiated with a UV lamp to a total dose of $900{\sim}1000mJ/cm^2$ The soft maid was then removed from the pressed barrier rib by winding up and fine pattern of barrier rib was obtained. The photosensitive barrier rib paste makes the demolding easy due to reduced interfacial forces and shrinking of paste materials.

  • This study was conducted to test the effect of Burns' cognitive-behavioral group counseling on depression and anxiety of industrial high school students. For this purpose, an experimental group and comparative group which was composed of 15 students respectively were assigned. The independent sample t-test between experimental group and comparative group about the degree of pre-test and after-test and the opposition sample t-test within each experimental group and comparative group were conducted. Analysis of Covariance was also applied. Results of the analyses showed that Burns' cognitive-behavioral group counseling program was effective in decreasing depression and anxiety. Implications of these results on student guidance and counseling were discussed. Suggestions for future research were presented and limitations were indicated.

  • Ni-doped $CoSb_3$ was prepared by the encapsulated induction melting and hot pressing, and its doping effects on the thermoelectric properties were investigated. Single phase $\delta-CoSb_3$ was successfully obtained by the subsequent heat treatment at 773K for 24 hours. Nickel atoms acted as electron donors by substituting cobalt atoms. Thermoelectric properties were remarkably improved by the appropriate doping.

  • It was difficult that we analysed the polymeric drugs for the physico-chemical properties. Sodium hyaluronate is a linear polysaccharide composed of repeating disaccharides of sodium glucuronate and N-acetyl glucosamine found throughout the tissues of the body with high concentrations in the vitreous humor. synovial fluid and umbilical cord. It has a role in regulating the interaction between adjoining tissues. (omitted)

  • 최근 의료 패러다임은 치료에서 예방과 관리의 개념으로 변화하고 있다. 특히 우리나라 성인 인구 중 20~30%에서 발견되는 만성질환은 예방과 관리가 더욱 필요한 성인병이다. 본 논문에서는 만성 질환 중 지속적인 치료와 예방 그리고 관리가 필요한 고혈압 환자들을 관리하기 위하여 생체 데이터, 검진 데이터, 문진 데이터, 생활 습관 등을 이용하여 순차패턴 방법을 적용한 고혈압 환자에 대한 약제 처방 시스템과 연관규칙을 적용하여 고혈압 환자들에게 24시간 관리가 가능하도록 하는 고혈압 환자 관리 시스템을 개발한다.

  • Purpose: This study was done to investigate the knowledge, attitude and prevalence status of Clonorchiasis Sinensis (C.S.) for inhabitants in the Nakdong riverside area. Method: Data were collected from December 16, 2008 to January 10, 2009. Participants were 552 people who responded to a questionnaire and had a stool examination. Results: The overall prevalence of C.S. was 13.8%. As for knowledge of C.S., the Clonorchiasis group had a mean score of 10.78 $({\pm}3.54)$ on a 17-point scale compared to a score of 10.58 $({\pm}4.15)$ for the negative group. The intended behavioral change related to risk of infection, according to presence of infection or not, was not significant but the Clonorchiasis group had a greater desire for behavioral change intention than the negative group. Conclusion: These results suggest that prevalence investigation of C.S. in all areas in the Nakdong riverside is needed and indicates that it is necessary to set up persistent and systematic management programs for patient care and prevention of C.S..
