The effects of intra-particle composition on the adhesive properties and water dispersity of acrylic emulsion type pressure sensitive adhesives (PSAs) were investigated. In the case of PSA having uniform intra-particle composition, the higher holding strength made the water dispersity lower. By changing the intra-particle composition in hard core/soft shell type, however, it was possible to get PSAs showing both high holding strength and water dispersity. When the weight ratio of MAA/AA is 4/1, high holding strength, but low initial tack and very low water dispersity were observed in both cases of higher contents of (AA+MAA) in core and shell area. When the weight ratio of MAA/AA is 1/4, however, higher water dispersity and lower holding strength were indicated in the case of higher contents of (AA+MAA) in shell area.

Free, soluble esterified and insoluble bounded phenolic acids were separated from Eungi chestnut endoderm. The composition and contents of phenolic acid were analyzed by gas chromatography, and their antioxidant activity was examined by DPPH assay, 2-deoxyribose oxidation, and ferric thiocyanate method. Gallic, ellagic, salicylic, and gentisic acids in free phenolic acid fraction, gallic, ellagic, and protocatechuic acids in soluble esterified fraction, sianpic and gentisic acids were the major phenolic acids in insoluble bounded fraction. Marked differences were observed in the phenolic acid composition and contents among the fractions. Free phenolic acid fraction showed the strongest antioxidant activity. Results revealed chestnut endoderm could be a potential antioxidant source containing gallic and ellagic acids.

The purpose of this study the following changes in the body composition and obesity-stress on the aerobic exercise and combined exercise and that Obesity Management Exercise Program was conducted to serve as the basis when developing materials. Obesity female college student 40 people were classified that Aerobic exercise group(20 patients) and combined exercise group(20 patients). Every time 60 minutes, three times a week, a total of eight weeks each exercise program after each underwent an exercise program compared body composition and stress. Research result, body fat is aerobic exercise group and combined exercise group was statistically decrease, Obesity Stress is founded that a significantly reduction in the combined exercise group. Therefore Obesity Management Exercise Program during development in considering the combined exercise group Obesity Stress is thought to be more suitable.

Objective: Objectives were to estimate energy and protein requirements of dairy crossbred steers, as well as to evaluate equations previously described in the literature (HH46 and CS16) to predict the carcass and empty body chemical composition of crossbred dairy cattle. Methods: Thirty-three Holstein×Zebu steers, aged 19±1 months old, with an initial shrunk body weight (BW) of 324±7.7 kg, were randomly divided into three groups: reference group (n = 5), maintenance level (1.17% BW; n = 4), and the remaining 24 steers were randomly allocated to 1 of 4 treatments. Treatments were: intake restricted to 85% of ad libitum feed intake for either 0, 28, 42, or 84 d of an 84-d finishing period. Results: The net energy and the metabolizable protein requirements for maintenance were 0.083 Mcal/EBW0.75/d and 4.40 g/EBW0.75, respectively. The net energy (NEG) and protein (NPG) requirements for growth can be estimated with the following equations: NEG (Mcal/kg EBG) = $0.2973_{({\pm}0.1212)}{\times}EBW^{0.4336_{({\pm}0.1002)}$ and NPG (g/d) = 183.6(±22.5333)×EBG-2.0693(±4.7254)×RE, where EBW, empty BW; EBG, empty body gain; and RE, retained energy. Crude protein (CP) and ether extract (EE) chemical contents in carcass, and all the chemical components in the empty body were precisely and accurately estimated by CS16 equations. However, water content in carcass was better predicted by HH46 equation. Conclusion: The equations proposed in this study can be used for estimating the energy and protein requirements of crossbred dairy steers. The CS16 equations were the best estimator for CP and EE chemical contents in carcass, and all chemical components in the empty body of crossbred dairy steers, whereas water in carcass was better estimated using the HH46 equations.

This study is on the feasibility of use of glycoprotein in various areas such as cosmetics and food etc. by extracting, isolating and refining glycoprotein from carrots, red ginseng extract residue, sesame and pine needles using protease(pepsin) and by analyzing general characteristics and measuring various bioactivities. The results of analysis of nutritional composition showed protein contents of glycoprotein. In the analysis of constitutive amino acids, the ratio of contents of hydroxy proline and glycine, the characteristics of glycoproteins appeared similar and the contents of glutamic acid and aspartic acid appeared higher. As a result of measurement contents of total polyphenol and flavonoid, it showed that glycoprotein had more contents generally, and the effect of bioactivity of glycoprotein appeared higher although different kinds of glycoprotein showed a little DPPH radical and nitrite scavenging ability, total antioxidant capacity by ABTS, ACE inhibitory.

The purpose of this study is to develop online educational contents and verify its effectiveness in order to strengthen the learning capabilities of college students. The theme of mind map online education contents is a mind map series for effective learning arrangement, and has been developed into a total of six contents. Each contents consisted of 20-30 minutes, and the details consisted of the concept, principle, learning case, how to write a mind map, and how to use a digital mind map. The results of the study are as follows. First, it was confirmed that the higher thinking ability of college students who took the mind map online education contents was improved. Second, it was confirmed that the self-directed learning attitude of college students improved after taking the mind map online education contents. Third, the reason why students' higher thinking ability and self-directed learning attitudes improved in this study is that they were developed in consideration of the composition of contents and appropriate video time. Therefore, in order to increase the effectiveness of online educational contents, it is necessary to examine specific cases using concepts from conceptual approaches to specific topics, and to faithfully reflect the procedure in which each learner can actually use the concept.

본 논문은 '사실주의' 계열영화에 나타난 극영화 촬영기법을 파악하여 내러티브의 극적표현과 시각적 연출법을 분석해 보는 것이 연구의 내용과 목적이다. 이는 한국영화역사라는 큰 흐름 안에서 촬영기법의 변화를 진단해 보고, 촬영자의 주요 표현수단중의 하나인 구도기법이 현대영화에서 어떻게 적용되고, 관객의 감정이입을 유도하는지를 탐구해 본다. 이는 현대예술영화에서 다루는 인간소외와 고립, 내적갈등의 문제들을 시각적으로 어떻게 형상화하고, 상징화하느냐의 방식과 그 중요성을 인식하는 것을 의미한다.
