The purpose of this research was to investigate the harmony evaluation and the effects used clues on harmony perception in terms of 32 tone on tone coloration of male shirt and necktie by male and female students when it comes to the coloration of male clothes shirts and necktie, after shirts matched necktie with warm and cool color, such as red, blue, and changed only value among three attributes of color. The results are as fellows. As to the red, light-dull, dull-dark was evaluated as harmonized coloration regardless of area-ratio by both male and female students. As to the blue, vivid-dark, light-dark, dull-dark was evaluated as harmonized coloration regardless of area-ratio by both male and femate students. Among 16 red tone on tone coloration stimuli, both female and male students evaluated the same 10 set as harmonized, but among 16 blue tone on tone coloration stimuli, female students evaluated 9 set, male students 12 set, so proved that male's range of harmony more extensive than that of female. It is significant difference between female and male on red dull shirt and vivid tie, blue dull shirt and dull tie combination. Females were positive to red dull shirt and vivid tie combination, males were negative, on the other hand, males were positive to blue dull shirt and dull tie combination, females were negative.

Based on a survey done recently in Japan, 30 percent of the serious accidents occurred in oral implant surgery were concerned with the mandibular canal and 3/4 of them were related to drilling. One of the reasons lies in the lack of the education system. To overcome this problem, a new educational system focusing on drilling the mandibular trabecular bone has been developed mainly for dental college students in the form of an oral implant surgery training simulator that enables student to sense the reaction force during drilling. On the other hand, the conventional system uses polymeric model. Based on these systems, two approaches were proposed; the evaluation by experienced clinicians using the simulator, and experimental works on the polymeric model. Focusing on the combination of the drilling force sensed and drilling speed obtained through both approaches, the results were compared. It was found that the polymeric models were much softer especially near the mandibular canal. In addition, the study gave us an insight of the understanding in bone quality through tactile sensation of the drilling force and speed. Furthermore, the clinicians positively reviewed the simulator as a valid tool.

This study demonstrate that polymeric microspheres composed of poly (ethylene adipate) (PEA) and poly (methyl methacrylate) (PMMA) can encapsulate and remarkably stabilize Broussonetia kazinoki root extract. We compared the long-term stability and the activity of Broussonetia kazinoki root extract in polymeric microspheres fabricated with different polymer ratio of PEA and PMMA. PMMA was incorporated to the PEA microsphere in order to reinforce the physical strength of microsphere, and there was no noticeable negative effect on the activity of Broussonetia kazinoki root extract. Optical microscope (OM), polarized microscope (PM), and scanning electron microscope (SEM) results showed that PMMA incorporated microspheres were very spherical and had smoothsurface. On the other hand, PEA microspheres showed relatively irregular morphology due to the low physical strength of microspheres. Moreover, the mushroom tyrosinase activities were measured for testing the inhibitory activity of Broussonetia kazinoki root extract encapsulated in polymeric microspheres, and these microspheres showed the effective suppression of mushroom tyrosinase activity. Consequently, polymeric microspheres produced in this study may be beneficial for the research of improving stability and protecting labile substances incorporated into the polymeric microspheres.
This study was performed to assess the extent of dietary diversity and nutrient intakes of Korean child-bearing women and to investigate the relationships between dietary diversity indices and nutrient intakes. A total of 91 women aged 18 to 48 years old participated. They were divided into four groups by age 15 subjects in teens, 20 in twenties. 32 in thirties and 24 in forties. Mean energy intake was 1638${\pm}$471㎉/day and it was low as 81.4% of the Korean RDA for energy. Mean intakes of folate, calcium and iron were also low as 81.7%. 72.6% and 57.2% of the RDAs. On the other hand, protein, vitamin A, thiamin, riboflavin and vitamin C were consumed close to or above the RDAs. It was obvious that the subjects in teens and twenties took less all of the nutrients as well as energy than those In thirties and forties. Mean nutrient adequacy ratio( MNAR) was 0.77 and showed a trend to raise with increasing age. Thus MNAR of the teens was the lowest and that of the forties was the highest among the age groups. The results in this study support the previous findings that nutrient intakes of women in teens and twenties were poorer compared to those in thirties and forties. Mean dietary diversity score( DDS) . dietary variety score(DVS) and dietary frequency score( DFS) were 4.1. 11.6 and 14.7. respectively. DVS and DFS of the teens and twenties were lower than those in thirties and forties. DDS significantly correlated to the intakes of energy and calcium only, however, DVS and DFS had significant relationships to the intakes of all nutrients. The MNAR significantly related to DVS and DFS. but not DDS. In conclusion, the intakes of energy, folate. calcium and iron of child-bearing women were not sufficient and their nutrient adequacy highly correlated with dietary diversity. It indicates that to consume various foods helps to enhance the nutritional status.
'I'his study investigated students' attitude toward mathematics. and how behavior/cognitive training affects level of math anxietv and level of math achievement. Subjects were all the freshmen attending Taejon Science High School, and they were given Mathematics Attitudes Scale and Attributional Style Questionnaire prior to and post training sessions. Twenty out of 84 freshmen voluntarily participated in nine sessions of training program. Participants were asked to do self-evaluation. Math achievement was measured prior to and post training. and was compared between two groups. Training program utilized behavior/cognitive approach. such as understanding one's feeling through muscle relaxation, breathing and meditation; modifying negative attributional style; imitating effective cognitive strategies for math problem solving, and so on. 'I'he result shows that students' math confidence in general was relatively low out of expectation, a nd they perceived teachers not supporting their math abilities :IS much as expected. On the other hand, students in general had strong math achievelment needs, and considered math utility very high. Sex difference was seen in the attitude toward female math abilities, to result that female students had more positive perception than male students. Female students of 'I'aejon Science High School seem free from conventional idea about female abilities including theirs. Participants' ~attitude change was compared with non-participants. and participants showed statistically significant change in their math confidence, and also in their math achievement. Participants had much higher math confidence and ~achievement than non-participants. And, they showed increased level of perceiving teachers' expectation. more realistic in needs, and more involvement in math. Math achievement was found positively related to math confidence, and participants' math achievement change was explained by their belief in math utility. Not only training program effect hut also participants' voluntary involvement and teacher\ulcorner' support of the program and participation seem to increase their math achievement. Based upon the result of study it was suggested that behavior-/cognitive training program be provided along with academic curricula for gifted students of Korea to help their emotional and psychological development enhance the efficacy of their cognitive learning.
In this study, achievement emotions were compared between the gifted and regular students. The significant differences for each group were shown in all eight elements respectively in lesson situation, learning situation and test situation. Among various achievement emotions, it was also found that the gifted students showed higher level of positive achiecement emotions. Furthermore, positive achievement emotions can have positive effects in increasing the achievement level in science subject. On the other hand, the negative achievement emotions were higher for ordinary students that could have negative effets. The influential factors were recognizing the values of Science, Science experiments, positive evaluation experiences, aggressive learning attitudes, interests and knowledge, positive self-perceptions, career relationships, and teachers' recognitions. These factors influenced in imcreasing students' positive achievement emotions and decreasing negative achievement emotions. By conducting in-depth advanced conversations with students based on the above results could increase students' interest and positive achievement emotions.
To elucidate the changes in physiological activities of Scutellariae baicalensis by heating, composition analysis with HPLC and evaluation of physiological activities of extracts were conducted. HPLC analysis of CW(water extract at room temperature) and CHW(heat treated CW) indicated that two distinctive peaks in the HPLC chromatogram were disappeared after boiling and additional peak was newly observed. This observation suggested that certain chemical changed in the extract occurred by heat treatment. In the estimation of physiological activities, CW showed higher ACE inhibiting activity than CHW. In the case of cytotoxic activity against cancer cells, CW exhibited higher activity than CHW against CCL-185. On the other hand, CHW showed higher activity than CW against HeLa, SNU-601 and HepG2. In addition, CHW showed the inhibitory effect on melanogenesis (80% inhibition) while CW did not show any activity.
Purpose: Number of the old-old elderly is rapidly increasing in Korea, but it is unclear whether there are differences between old-old and young-old elderly in nutritional status, nutrient intakes and health status. The gender differences in Korean elderly in these conditions also remains unknown. This study, therefore, investigated gender-associated differences in nutritional, health status and nutrient intakes and how they are related among young-old and old-old homebound elderly. Methods: Two hundred and eighty elderly who were attending a local elderly welfare center were recruited. Evaluation included demographic, nutritional and health status related data, nutritional intakes, and life style related factors including physical activity. Results: Of the 280 subjects, old-old were 147 (52.5%) and young-old were 133 (47.5%). Male old-old elderly had more often abdominal obesity than female old-old, but male old-old more often had malnutrition than female old-old. There were few differences in nutrient intakes between old-old male elderly and female elderly after energy intakes were controlled. Male old-old more often had less intake of beta carotene and Vitamin A than female old-old. On the other hand, male old-old elderly more often had hypercholesterolemia and hypertension than male young-old. Conclusion: Male old-old may be at a greater health and nutritional risk than female old-old. Targeted nutritional intervention for male old-old emphasizing antioxidant nutritional intakes may be warranted.

Effect of preparation method on Yulmoo kimchi(watery kimchi prepared with Yulmoo, leaf radish) fermentation was investigated by measuring physicochemical, microbiological and sensory properties for 20 days. Yulmoo kimchi was fermented at 4$^{\circ}C$ after keeping at room temperature(27$\pm$0.5$^{\circ}C$) for 8 hours. Four types(A, B, C, D) of Yulmoo kimchi were prepared. Sample A was made without wheat flour paste and red pepper powder and sample B was made with wheat flour paste. Sample C was made with red pepper powder, and sample D was made with wheat flour paste and red pepper powder. pH was slowly lowered and stabled after 10 days in all samples. Total acid content increased in all samples. Reducing sugar content initially increased and decreased thereafter. Especially, reducing sugar content of sample B increased in the early stage of fermentation and maintained initial reducing sugar content after 20 days. Total vitamin C content reduced during fermentation in all samples. Especially initial total vitamin C content of sample D increased more than those of other samples relatiely. Lightness and yellowness showed no difference, but on the other hand redness increased gradually in all samples. The number of lactic acid bactgeria reached maximum value in 10~13 days with the total cell numbers and gradually decreased thereafter in all samples. The number of lactic acid bacteria and total cell number of sample D was much more than those of any other samples. As a result of the sensory evaluation, Yulmoo kimchi showed significant difference in all characteristics. Sample D showed the highest scores in all characteristics before 10 days of fermentation. However, after 10 days sample B showed the highest scores.

Fermentation patterns of apple Gochujang mash prepared with different addition times of red pepper powder were investigated. Red pepper powder was added into Gochujang mash before and after fermentation of the mash. In the apple Gochujang mash without red pepper powder, viable yeast cell counts of Zygosaccharomyces rouxii Y-80 increased to 6.5 log CFU/g shortly after five days of fermentation, and ethanol concentration reached its maximum value (3.8% of the total volume) after 15 days of fermentation. On the other hand, in apple Gochujang mash prepared by the initial addition of red pepper powder before fermentation, viable yeast cell counts increased to 7 log CFU/g after 20 days of fermentation, and ethanol concentration reached 1.3% after 25 days of fermentation. Yeast growth and ethanol production were stimulated in the Gochujang mash without red pepper powder. Sensory evaluation scores were similar in the apple Gochujang regardless of addition time of red pepper powder.
