The purpose of study is to identify influences of attribution of university headquarters, executive direction and management, student three groups - establishment･ establishment, management, entrance - to the performance evaluation index. This study offers development plan of the public sector honors college by analysing difference in group consciousness to the comparative significance of performance evaluation index for co-creation. The study attempt to investigate attribution theory and difference in group consciousness based on the 1st actions of 3 group results(establishment･ establishment, management, entrance) affect the performance evaluation indexes. For that, this study has developed 19 indicators, 5 Items for performance evaluation using program logic model and AHP method focusing on the seokdang honors college of Dong-A University. Analysis was pronounced differences between groups consciousness. University headquarters perceived the number of people passing exams, employment rates than other groups as important factors because university provides various benefits to attract talented student. On the other hand, executive direction and management perceived performance index of consultation program, training, attendance, the number of host because student motivation recognized as important. Student who demand for education services are recognized scholarship benefits(budget), the number of people passing exams of imput･initiative outcome item as major factors by opportunity costs for entrance to university located in Seoul. The study results suggest need for student･parents satisfaction as key performance indicator, good communication within the 3 groups of public sector honors college in order to improve the quality of operation since awareness about 17 of 19 performance indicators was a big gap. The study shows need for maintaining consistency･durability in government s policy to foster motivated talent in the community and joint venture creation.

Leuconstoc mesenteroides와 Lactobacillus bulgaricus를 이용한 고점도의 발효유 제조에 관한 조건을 검토하였다. 발효유 제조의 최적 조건은 Skim milk 10%, yeast extract 0.2%, sucrose 10% 및 pH 6.8이였으며 배양온도는 30℃가 가장 좋았다. 접종비율에 의한 점도는 Leuconostoc mesenteroides와 Lactobacillus bulgaricus의 접종비가 1 : 1일 때 가장 높은 점도를 보였다. 수소이온농도는 혼합배양이 각각의 단독배양에 비하여 낮게 나타났으며 배양 12시간부터 높은 산도를 유지하였다. 24시간 배양한 혼합발효유의 총생균수는 8.7×10^9으로 단독배양의 경우보다 높게 나타났으며 이때의 점도는 2750 cps이었다. The conditions for the production of viscosity fermented milk by mixed culture method using Leuconostoc mesenteroides and Lactobacillus bulgaricus has been studied. The media composition and culture condition for optimum production of viscosity fermented milk were as follows: 10% f skim milk, 0.2% of yeast extract, 10% of sucrose, pH 6.8 and 30℃. Highest viscosity of culture broth was obtained with the same inoculation ratio of each microorganism. The final pH or mixed culture fermentation broth was ower than that of single culture broth of each microorganism. The total number of lactic acid bacteria and viscosity in final mixed culture broth after 24 hours of inoculation was 8.7×10^9 cells/m/ and 2750 cps. respectively.

가교폴리스티렌의 염화벤조일화 高分子反應

全東源,朴景惠 梨花女子大學校 韓國生活科學硏究院 1988 韓國生活科學硏究院 論叢 Vol.41 No.-

가교도가 상이한 고분자 resin matrix의 고분자 반응성을 조사하기 위해서 divinylbenzene (DVB) 가교 polystyrene을 염화벤조일화 시켰다. 반응온도와 polystyrene/p-chlorobenzoylchloride(p-CBC)/AlCl_2의 비율이 염화벤조일화에 미치는 영향이 조사되었다. 가교도가 상승되거나 반응온도가 50℃에서 30℃로 낮아지면 gel type polystyrene에서는 p-CBC의 도입이 크게 감소되지만 macroporous type에서는 p-CBC의 도입이 크게 감소되지 않는다. p-CBC의 초대도입은 polystyrene/p-CBC/AlAl_3의 비율 1/2/0.5(mole ratio)에서 얻어진다. DVB 2%, 5%가교에서 반응개시 6∼10시간만에 최대염소함량에 도달된이후 서서히 염소함량이 저하하고 있어 자동가교의 가능성 배제할 수 없다 Divinylbenzene (DVB)-crosslinked polystyrene of different degree of crosslinking was chlorobenzoylated to examine the reactivity of polymeric reaction. The effect of reaction temperature, and the ratio of polystyrene/p-chlorobenzoylchloride (P-CBC)/AlCl_3 on the chlorobenzoylation was investigated quantitatively. When the degree of crosslinking of crosslinked polystyrene rose or the reaction temperature lowered from 50℃ to 30℃, the introduction of P-CBC decreased greatly in gel type polystyrene, but in the macroporous type, great decrement was not found. Maximum amount of introduced P-BCB could be obtained when the ratio of polystyrene/P-BCB/AlCl_3 was 1/2/0.5 (mole ratio). The fact that the chlorine content attained to the maximum in only 6∼10 hours from the beginning, thereafter decreased slowly in DVB 2%, 5% crosslinking enables to get a idea of autocrosslinking.

Purpose: We determined the use of scrotal ultrasonography in the initial diagnosis and management of testicular injuries due to blunt scrotal trauma. Mateiials and Methods: We reviewed 54 patients of scrotal trauma in the last 8 years. Forty patients were evaluated by ultrasonography preoperatively. A heterogeneous echo pattern of the testicular parenchyma with loss of oval shape, contour definition was the basis for diagnosis of testicular rupture. Among them, 33 cases underwent scrotal exploration and 7 cases were managed conservatively. The remaining 14 patients were evaluated only by physical examination, 8 patients of them were explored immediately because of suspicious testicular mpture. The accuracy of ultrasonography were determined by comparing radiographic interpretations with intraoperative findings. Results: Among the 33 patients who were evaluated by ultrasonography and explored immediately, there were 26 suspected testicular ruptures on ultrasonography. Surgical exploration revealed testicular rupture in 23 and simple hematoma in 10. The testicular rupture was correctly diagnosed by ultrasonography in the 22 cases, and there were 4 false-positive and 1 false-negative diagnoses of testicular rupture. The sensivity and specificity for the diagnosis of testicular rupture are 96% and 60%, and the positive and negative predictive values are 85% and 86%, respectively, Conclusions: Scrotal ultrasonography, with the main radiographic finding of a heterogeneous echo pattern of the testicular parenchyma with loss of oval shape, contour definition, is highly sensitive on the diagnosis of testicular rupture. And it increases the salvage rate for testicular rupture with preservation of the testicular function and prevents delayed complications of chronic pain, atrophy and orchiectomy associated with missed testicular rupture.
