The purpose of the research was to investigate the organizational integration process of the university library, computer center and other informa ion related operations. The research process follows : first, the literature review of the organizational integration of the information related operations. second, analysis of the organizational integration in Korea. third, the organizational integration of information related operation in US and Japan, then the case analysis of information related organizational integrations in Korea. This process lead us to point out few problems and pitfalls that could occur in the integration procedure. The total integration procedure has turned out to be the most effective in the University environment. And for the management of fully integrated organization. Vice-President and Chief Information Officer, - who is reponsible to suggest vision, leadership and ability to cope with the complex nature of the future information society - was strongly suggested.

A feeding trial was conducted with Euglena strains grown under different media. The effect of supplementation of Euglena on the performance, nutrient availability and fatty acid composition of breast muscle was studied. In experiment I, two hundred ten hatched broiler chicks (Ross) were assigned to seven dietary treatments for 5 weeks. Each treatment consisted of 3 replications with 10 birds each. Control diet was formulated to have $22\%$ CP and 3,150 kcal ME/kg for starter diet, $19\%$ CP and 3,200 kcal ME/kg for finisher diet. Euglena gracilis Z. (EG) was added to control diet at the plevel of 0.25, 0.5, $1.0\%$ and Euglena gracilis Z. bleached and DHA enriched (EGBD; a strain mutated by streptomycin and cultivated in DHA enriched medium) at the level of 0.5, 1.0, $2.0\%$ in the diet. In experiment 2, two hundred fifty hatched broiler chicks (Ross) were assigned to five dietary treatments: T1; Control, T2; T1 + Euglena gracilis Z. DHA enriched (EGD; cultivated in DHA enriched medium) $0.5\%$, T3; T1 + EGD $1.0\%$, T4; T1 + EGBD $0.5\%$, T5; T1 + EGBD $1.0\%$. The weight gain and feed consumption were measured weekly. Fatty acid composition of breast muscle was determined. In experiments I and 2, Euglena supplementation had no significant effects on weight gain, feed intake and feed conversion ratio. In experiment 1, EGBD treatments significantly increased DHA concentration but decreased concentration of linoleic acid and arachidonic acid in breast muscle. EGBD 2% treatment showed the highest DHA concentration (14.27%) which is 3.9 times of that of the control ($3.66\%$). In experiment 2, $1.0\%$ EGBD treatment showed highest EPA, lignoceric acid and DHA level in breast muscle (P<0.05). Also, EGD treatments significantly increased DHA and EPA concentration. It was concluded that EGBD and EGD can be supplemented to broiler diet to produce DHA enriched broiler meat.

A total of 120 pigs were used to investigate the effect of feeding probiotics on physico-chemical properties and sensory evaluation of pork loin. About 50kg pigs were randomly alloted into one of six experimental diet groups (C1:commercial diet feed the gilt; C2:commercial diet feed the barrow; T1:$0.5\%$ YC2000 feed the gilt T2:$0.5\%$ YC2000 feed the barrow; T3:$0.1\%$ YC2000 + $0.3\%$ KBC1121 feed the gilt; T4:$0.1\%$ YC2000 + $0.3\%$ KBC1121 feed the barrow). Pigs were slaughtered at approximately 110kg live weight. Crude fat and crude ash were not difference among the treatments. However, water content was higher in T1 and T2 compared to other treatment and the protein level of T3 was higher than those of other treatments. All of dietary probiotic groups showed higher pH compared to control. Especially, pH of T1 and T2 were higher among the dietary probiotic groups. Cholesterol level of dietary probiotic groups were lower compared to control. In meat color, $a^{*}$ was higher in T1 and $b^{*}$ was lower in T2 compared to other treatments. In sensory evaluation of cooked meat, aroma, flavor, tenderness, juiciness and overall palatability were higher in control, whereas T3 and T4 showed higher score in tenderness, juiciness and overall palatability. T3 had higher myristic acid. palmitoleic acid and oleic acid, whereas arachidonic acid was lower in T3. In conclusion, dietary probiotic groups were much better than other treatments in cholesterol, color, tenderness and juiciness. But drip loss of dietary probiotic groups showed higher due to lower pH compared to control.

This study was conducted to determine the effect of pH adjustment on physico-chemical characteristics of chicken breast surimi. The chicken breast meat was ground with distilled water, of which pH was then adjusted to 2.5 (T1), 3.0 (T2), 10.5 (T3) and 11.0 (T4) for surimi manufacture, respectively. Water content was higher in order of T4>T1>T3>T2 (p<0.05). Crude protein and crude fat were higher in T3 and T4 compared with T1 and T2 (p<0.05). $L^*$ values, myofibrillar protein and water holding capacity of T2 and T4 were higher than those of T1 and T3 (p<0.05). T4 had the lowest yield among the treatments (p<0.05). T1 was higher in yield and pH, whereas breaking force and deformation were higher in T1 (p<0.05). $a^*$ was higher in order of T3>T2>T4>T1 and $b^*$ was lower in T1 compared with other treatments (p<0.05). In textural properties, the chewiness values of T2 and T3 were higher than those of T1 and T4, the hardness was higher in order of T2>T3>T4>T1 (p<0.05). Cohesiveness and gumminess of T1 showed higher values than those of other treatments (p<0.05). In sensory evaluation, the note for appearance was higher in T2 than other treatments (p<0.05), however other traits were not significantly different (p>0.05). Therefore, the alkaline processing (T4, pH 11.0) would be recommended.

본 연구는 유기농 채소와 돈지방, 올리브유를 각각 3%씩 첨가하여 저지방 햄버거 패티의 제조 및 포장방법을 달리하여 $7{\pm}1^{\circ}C$에서 25일간 저장하면서 물리화학적 및 미생물학적 성상을 조사하였다. 모든 처리구들의 pH는 저장기간이 경과함에 따라 증가하다가 저장 15일째를 중심으로 감소하였으며(p<0.05) 저 장기 간 동안 올리브유를 첨 가한 T2시료구가 대조구 및 다른 시료구에 비하여 높은 pH를 유지하였다(p<0.05). TBARS는 대조구에 비하여 각 시료구들이 비교적 낮은 값을 나타내었으며. 특히 식물성 저지방 햄버거 패티의 시료구가 저장기간 동안 가장 낮은 값을 나타내었다(p<0.05). 대조구와 모든 시료구들이 5일 이후부터 증가하는 경향을 보였고 대조구는 저장 15일, 각 시료구는 저장 20일 경과 후 가식권을 벗어났다. 하지만 올리 브유를 첨가한 식물성 저지방 T2시료구의 TBARS value는 저장 20일 이후 가식권을 넘었다. 총균수의 변화를 보면, 각 처리구 중 대조구는 저장 15일 이후부터 7 log CFU/g로 가식권을 넘어섰으며, 각 시료구의 경우에는 저장 20일 경과 후 가식권을 벗어난 것으로 보아 대조구에 비하여 다소 저장기간이 연장됨 을 알 수 있다.

This study aimed to analyze the trends of studies on estimation of cost for early childhood education and child-care services provided by both the kindergarten and child-care centers. A total of 21 papers including academic journals and policy research reports were collected. The papers were analyzed with the annual trends, research contents, and estimation methods of cost for early childhood education and child-care services. The main results of this study were as follows. Firstly, the studies on estimation of cost for early childhood education were performed earlier than the ones on estimation of cost for child-care services. The research contents were composed of analyzing operating expenses and estimating cost for early childhood education and child-care services. Secondly, there were similarities in the estimating processes of cost for early childhood education and child-care services, but the definition of operating expenses used for the estimation of cost differed. Thirdly, there were differences in the items of operating expenses inputted to estimate cost and in the calculation procedures of items in studies. Finally, based on the results, this study suggested what future studies and policy should consider in the estimation of cost for early childhood education and child-care services.
