This study investigated the quality characteristics of Haengbyung using dry rice flour added with various amounts (0, 20, 40, 60%) of raw and steamed apricot juice. The moisture contents, color values, pH, texture and sensory evaluation(attribute difference and acceptance) for the samples were tested. The moisture content (p<0.001) and pH(p<0.001) of the Haengbyung significantly decreased with the increase of apricot juice. As for the color of the Haengbyung samples, the higher percentage of the apricot juice showed the lower L-value (p<0.001), and higher a-value(p<0.001) and b-value(p<0.001). Texture profile analysis of Haengbyung samples showed that hardness(p<0.001) and gumminess(p<0.001) increased, while adhesiveness(p<0.001) and cohesiveness(p<0.05) decreased with increasing amounts of apricot juice. An attribute difference test of Haengbyung samples showed that appearance(apricot color(p<0.001) and dryness(p<0.001)), flavor(sour(p<0.001), acerbic (p<0.001), and green fruit(p<0.001)), and taste(sour(p<0.001), acerbic(p<0.001), and astringent(p<0.05) as increased as apricot juice amounts increased. The control and Haengbyung sample with 20% of apricot juice (both raw and steamed) showed the highest acceptance in taste, texture, and overall acceptability in consumer ranking testing.

Purpose - The purpose of this study is to investigate the difference in the degree of significance and satisfaction perceived by college students and ordinary consumers on the HMR product attributes. Comparison of the difference on HMR product attributes between ordinary consumers and college students who belong to the current and future consumption groups of HMR will provide information for clear marketing strategies and PR on target consumers from the aspects of companies. Also, overall difference on HMR was investigated through IPA(importance-performance analysis) on significance and satisfaction with each product attribute. This result will provide information to food companies that produce or supply HMR products to be supplemented and improved. Finally, IPA was conducted between groups on product attribute to find which difference exists between groups. This result is also expected to provide crucial information to companies as suggested in the first purpose. Research design, data, and methodology - The procedure of analysis is as follows. First, independent sample t-test was conducted on the significance and satisfaction on HMR product attributes. Second, with using IPA, the significance and satisfaction on HMR product attributes of the respondents were checked to investigate marketing strategy direction on overall HRM products. Third, the difference between generations was verified using IPA on the college student and consumer groups. According to this result, the direction of marketing strategy on HRM products was to be proposed to food companies. Results - It was known that consumers consider HMR product attributes statistically and significantly such as nutrient content(nutrition), country of origin, brand, main raw material, packaging, and awareness of manufacturer. They keep after purchase more importantly than college students who considered only volume and price than consumers. In comparison with the difference in satisfaction on HMR product attributes, the college student group was more satisfied than ordinary consumers only in flavor, condition of food additives, and volume. Also, HMR related food companies must maintain taste, cooking method, manufacturing date, expiration date, and safety on current products continuously. Finally, as a result of analysis from the groups, the attributes such as cooking method, manufacturing date, expiration date, and safety were considered significantly with high achievement by the two groups. It was known that college students considered food texture to be important, but consumers considered storage method to be important after purchasing it. Conclusions - There is necessity to differentiate effectiveness of products when releasing HMR products subject to consumers and college students. The result will give great assistance to the improvement of companies, produce or supply HMR products. It will also provide entry strategies on target groups of companies that are planning for entry. The factors that consumers commonly considered not to be significant were brand, package form(appearance), cooking time, and sale(purchase) location, which were found in the comparison with the groups that awareness about manufacturers and storage method after purchase corresponded to college students and that distribution route corresponded to ordinary consumers.

Recently, various strengthening methods using carbon fiber sheets (CFS) have been developed for the rehabilitation of structures and applied to the concrete member. However, still research need arises in order to verify the structural capacity of RC member which experienced bond loss between concrete and CFS after strengthening. This is because previous research has focused on the development of design process and evaluation of structural capacity only for retrofit. The appearance of this loss may be initiated at just after retrofit construction. And it will be more serious when the layer number of CFS increases. In order to minimize above mistake in retrofit design using CFS, more exact evaluation process to predict the bond loss of CFS is required. The objective of this research is to study the variation of flexural structural capacity of beam which has experienced bond loss after strengthening using CFS. Experimental and analytical study are performed and evaluation of the previous formula is conducted. Test result showed that the significant strength deterioration was not found until the bond loss of 20%. Overall structural behavior of the beams can be predicted by nonlinear sectional analysis.

This treatise begins with finding a meaning of Paul Klee's . It is pretty simpleto choose the square of Klee. The most important formative language for twenty century is abstraction. The element of speaking for abstraction issquare. The artists are trying to contain the nature and universe in the square. The role of magic square consisting with small squares of Klee is crystallized. The other side, the test of this study is a method analysis. The method analysis is changing while concept and style have been changing according to a period. The existing method analysis is an iconology used many times in Art history. This treatise introduces France symbolists, Bernard Cocula and Claude Peyroutet's analysis of a meaning of image(Semantique do l'image) who were applied to Modern Art. based on Iconography. It also applies to analysis of artwork of Klee. Cocula's is developed from one phase to five phase step by step. The first phase deals with an appearance of artwork. Subsequently, the second phase is directly adjacent to personal feeling and impression. This is an adequate method for image study in the analysis of modern arts. This phase makes it a rule to enjoy talking with artworks above all. The third phase begins with this question 'What do you see? (que voyons-nous?).' The applies exhaustively and strictly to complicated image artworks which need an elaborate analysis. It is very hard but audiences must try to maintain neutrality in front of artwork because cord formation and interpretation should be formed objectively. The meaning analysis and interpretation of the forth phase begins with this question 'what is the image rouse'(qu'evoque cote image?).' This phase is the most important in a process of symbolic analysis. The audience investigates personal elements and common elements. The fifth is synthetic analysis and interpretation phase. The synthesis is last phase and it reaches a valuation and a conclusion. Namely, the synthesis phase makes up synthesis conclusion, summarizes image character, and completes value adjudication. Sometimes it completes no conclusions in a silence. This study found a new possible analysis example from Paul Klee's work. The study emphasizes square analysis and interpretation and uses . The analysis of artwork by Cocula's is an example of the most important work of Klee's three artworks. The first analysis of artwork is and the second one is . The third one is . In these analyses, Klee usedmagic square 'to make natural pictorial element and to explain organic living things.'

The concrete wall is the most useful of retaining structure which can obtain the engineering stability, but has problems that is not friendly with nature environment in a fine view, such as poor rear drainage, and shrinkage crack by temperature difference, etc. Because of this problems, the research for a segmental crib retaining wall has been performed. A segmental crib retaining wall is quickly and easily erected because is possible to be erected as the individual members, and is not sensitive to differential settlement and earthquakes. Also, it shows effective drainage and has a friendly advantage with nature environment because of being able to be planted with vines and shrubs in retaining walls The design of crib retaining walls has traditionally been based on classical soil mechanics theories. These theories, originally derived by Rankine(1857) and Coulomb(1776), assume that the wall acts as a rigid body. This assumption results in failure being predicted by either monolithic overturning or base sliding mechanisms. However, the wall consists of individual members which have been created a three dimensional grid. This grid confines an fill mass which becomes part of the wall. The filled wall resists the earth pressure with the same mechanism of classical gravity walls. Because of the flexibility of the individual segment, it allows relative movement between the individual members within the wall. The three dimensional flexible grid leads to stress redistribution when the wall is subjected to external or fill loads. Due to the flexibility and the stress redistribution, the failure of segmental crib wall consists of not only overturing and base sliding but the local deformation and the failure between the segmental members. It has been researched in the field that due to this flexibility and load redistribution, serviceability failure of segmental crib walls is unlikely to be due to overturning or base sliding. Therefore, in this study, the relative displacement appearance of retaining wall due to variation of inclination is measured to examine this behavior characteristics. Also, the behavior characteristics of retaining walls by surcharge load, and location of acting point of retaining wall rear, and the displacement characteristics and deflections are estimated about the existence and nonexistence of Rear Stretcher performing an role in transmitting earth pressure of Header and Stretcher organizing retaining walls. This research focuses on the characteristics due to the behavior of retaining walls. This research focuses on the characteristics due to the behavior of retaining walls.

As pumpkin is gaining popularity as health functional food among people, this study purposed to prepare powder pumpkin soup of instant food style using ordinary pumpkin (Cucurbita moschata Duch.) that is an oriental pumpkin variety, and sweet pumpkin (Cucurbita maxima Duch.) that is a western pumpkin variety, and to examine its mechanical and sensory characteristics. The viscosity of powder pumpkin soup was higher when the addition ratio of ordinary pumpkin powder was higher than that of sweet pumpkin powder. On the contrary, sugar contents was higher when the addition ratio of sweet pumpkin powder was high. Color did not show any consistent tendency by the addition ratios of ordinary pumpkin powder and sweet pumpkin powder, and lightness was highest in PS2, redness in PS3, and yellowness in PS1. In the results of sensory evaluation through quantitative descriptive analysis, color, glossiness, and the intensity of pumpkin smell were highest in PS3, the intensity of sweetness in PS1, the intensity of saltiness in PS4. In the results of sensory evaluation through palatability test, PS3 showed the highest palatability in terms of appearance, flavor, color, taste, concentration, mouth feel, and overall palatability. Summing up these results, when powder pumpkin soup was prepared at different mixture ratios of ordinary pumpkin powder and sweet pumpkin powder, PS3 showed the most superior mechanical and sensory characteristics. Thus, it is considered most adequate to prepare powder pumpkin soup at the mixture ratio of ordinary pumpkin powder 75% and sweet pumpkin powder 25%.

The objective of this study was to investigate the physicochemical properties of rice flour at different degrees of milling (DOM) and their influence on cooking, color, textural, and sensory properties of rice noodles. Higher DOM flour resulted in higher value of lightness and lower value of yellowness. Transition temperatures of rice flour were not significant, whereas the enthalpy of gelatinization increased with an increase in milling degree. Rice noodles were prepared with rice flours of DOM, and their quality and sensory properties were investigated. Cooking properties of rice noodles were not affected by DOM; however, color values were affected by DOM. In textural properties, values of hardness and chewiness of rice noodles were significantly reduced with an increase in milling degree. The sensory scores for overall acceptability, appearance, and texture were highest in higher DOM noodles (DOM 10% and DOM 12%).

In recent years, there has been an increasing interest in research on gluten-free bread. Most studies have focused on substituting or imitating the gluten network. However, less attention has been paid to technological approaches to improve the quality of gluten-free rice bread (GFRB). This study analyzed the influence of the temperature of water used for kneading and fermentation time on the quality of GFRB. Water at various amounts and different temperatures was added for kneading, and fermentation was performed for 0, 2, and 4 h. GFRB produced by kneading using water at 95℃ showed the highest specific volume and the lowest hardness among test groups, regardless of other factors. In conclusion, mixing equal volumes of water at 95℃ and rice flour, followed by a 2 h fermentation process, produced the best-quality GFRB in terms of cross-sectional area, hardness, and appearance.

Purpose: We studied magnetic resonance imaging of acromion morphology and superior displacement of the humeral head in the patients with diagnosis of rotator cuff impingement syndrome, and also documented the relationship of type Ⅲ acromion to the rotator cuff tear. Materials and Methods: We reviewed retrospectively 40 patients(40 shoulders) who had arthroscopic treatment for the diagnosis of stage II impingement or rotator cuff partial tear and did not have other risk lesions except acromion factor. The mean age was 48.7 years at operation. 21 men(2l shoulders), mean age of 26 years, were used as controls. Acromial type, tilt, and superior displacement of humeral head in sagittal plane, and acromial lateral angulation in coronal plane were measured. Four parameters of the patients were compared with those of control group. And then, the data were subdivided and analyzed with respect to acromial type and patient age in the impingement group. Student t test and multi-way ANOVA were used. Results: In impingement group, Farley's type I acromion, 33%, type Ⅱ, 38%, type Ⅲ, 27% and type Ⅳ, 2%. Superior displacement of humeral head( 4.8mm) were characteristic in the impingement group compared with the control group(1.3mm)(p<0.05). But acromial tilt and lateral angulation were not statistically different. In the analysis of the impingement group, the change of 4 parameters was not significant with respect to age(p>0.05), but lateral angulation in type I acromion(18 degree) and superior displacement of humeral head in type Ⅲ acromion(6.3mm) were significantly increased(p<0.05). All 4 parameters were not different between two subdivided types of type Ⅲ acromion. Conclusion: All types of acromian and large lateral angulatian cauld develop impingement syndrame, but acromial tilt was nat risk factar. Appearance of type Ⅲ acromian and increased superiar displacement of humeral head were characteristic findings in the impingement syndrame. Superiar displacement of humeral head as a result of degenerative change of rotatar cuff was probably primary cause far impingement. The type Ⅲ acromian might be an acquired farm, which cauld be expected to accelerate the tear of rotatar cuff as a cansequence.

DW-166HC ($^{166}$ Holmium ($^{166}$ Ho)-Chitosan complex) is a new radiopharmaceutic anticancer agent with a broad anti-tumoriginec spectrum, especially against human fepatic cancer. DW-166HC was evaluated for the appearance of micronucleus in polychromatic erythrocytes (PCEs) of mouse bone marrow cells after subcutaneous and intravenous single administration. Bone marrow cells were prepared at 24 hr and 48 hr after DW-166HC-I ($^{165}$ Ho-Chitosan complex cold compound) administration and at 24 hr, 72 hr and 2 weeks after DW-166HC ($^{166}$ Ho-Chitosan complex : hot compound) administration. The results showed there was no statistically significant increase of the numbers of PCEs with micronucleus in all DW-166HC-I administered groups compared with a negative control group but there was statistically significant increase of the numbers of PCEs with micronucleus at 24 hr and 72 hr in all DW-166HC administered groups, which was recovered after 2 weeks from the drug administration. The results also showed the ratio of normochromatic erythrocytes (NCEs) to PCEs of all DW-166HC-I administered groups was not significantly different from that of a negative control group but there was significant difference this ratio at 24hr and 72 hr in all DW-166HC administered groups compared with that of negative group, which was also recovered after two weeks from the drug administration. These results suggested that DW-166HC-I may not cause any chromosomal damage but DW-166HC has in vivo mutagenic potential because of its radioactivity.
