Objective: Information about the chemical composition of cassava-based feed ingredients is needed to accurately formulate animal diets. A study was conducted to determine the chemical composition of cassava-based feed ingredients and to test the hypothesis that there is variation in chemical composition among cassava products originating from different South-East Asian countries. Methods: Sources of dried peeled and unpeeled cassava roots, cassava chips, cassava meal, high-ash cassava meal, and cassava residue were used. All samples were analyzed for dry matter, gross energy, nitrogen, amino acids (AA), acid-hydrolyzed ether extract (AEE), ash, minerals, total starch, insoluble dietary fiber, and soluble dietary fiber. Samples of peeled and unpeeled cassava roots, cassava chips, and cassava meal were also analyzed for sugars. Results: High-ash cassava meal had greater (p<0.05) dry matter and ash, but lower (p<0.05) total starch and gross energy than all other cassava products. Peeled cassava roots, unpeeled cassava roots, and cassava chips had greater (p<0.05) total starch than the other cassava-based ingredients. Cassava residue had greater (p<0.05) concentrations of lysine, insoluble dietary fiber, and soluble dietary fiber compared with the other cassava products, but tryptophan and glutamic acid were greater (p<0.05) in peeled cassava roots, cassava chips, and cassava meal samples compared with the other ingredients. Concentration of most minerals was greater (p<0.05) in high-ash cassava meal than in the other cassava products. Conclusion: Cassava-based ingredients sold as peeled roots, unpeeled roots, chips, or meal have chemical compositions that are not different from each other, and peeling has little impact on chemical composition. High-ash cassava meal has lower nutritional quality compared with other cassava products due to low starch and gross energy. The high fiber content in cassava residue makes this ingredient more suitable for ruminants and sows than for younger pigs or poultry.
The purpose of this study is to analyze how the organizational structure, task group functioning and need styles have influence on the conflicts handling styles such as integrating, avoiding, dominating, obliging and compromising as the employee's personality engaged in the service industry. This study uses the hierarchical regression analysis method. Data were collected by the survey method from employees engaged in the service industry located Seoul, the Province of Gyeonggi, and the Province of Gangwon. The study result shows that to the employees with the type A style, need styles are significantly related to the conflicts handling styles such as avoiding. But to the employees with the type B style, need styles are significantly related to the conflicts handling styles such as integrating and avoiding. On the other hand the result shows that the higher the need for achievement and the lower the need for autonomy, employees with the type B style prefer integrating styles to other conflicts handling styles. Or the higher the need for dominance, employees with the type B style prefer dominating styles to other conflicts handling styles. And the higher the need for dominance, employees with the type A style prefer dominating styles to other conflicts handling styles. The study result shows that to the employees with the type A and type X style, task group functioning are significantly related to the conflicts handling styles such as obliging and compromising. But to the employees with the type B style, task group functioning are significantly related to the conflicts handling styles such as obliging and dominating. On the other hand the result shows that the lower faith in peers and management and the higher confidence in peers and management, employees with the type B style prefer obliging style to other conflicts handling styles. But the higher group homogeneity and group cohesiveness, the lower faith in peers and management and the higher confidence in peers and management, employees with the type X style prefer obliging style to other conflicts handling styles. And the higher confidence in peers and management, employees with the type A style prefer compromising style to other conflicts handling styles. The study result shows that to the employees with the type A, organizational structure functioning are significantly related to the conflicts handling styles such as avoiding, obliging and compromising. But to the employees with the type X style, organizational structure functioning are significantly related to the conflicts handling styles such as dominating. On the other hand the result shows that the higher role conflict, the lower role ambiguity and the higher communication system, employees with the type A style prefer avoiding style to other conflicts handling styles. But the lower role ambiguity, employees with the type X style prefer compromising style to other conflicts handling styles. To conclude from these results, employees with the type A style have influence on the organizational structure functioning to other factors on the preference of the conflicts handling styles. And employees with the type B style have influence on the needs styles to other factors on the preference of the conflicts handling styles. Or employees with the type X style have influence on the task group functioning to other factors on the preference of the conflicts handling styles. Although this study provides several managerial implications, this study has some limitations. Specifically data were collected from only the service industry in Seoul, the Province of Gyeonggi, and the Province of Gangwon. In spite of the limitations, the study results could be used valuably in case of the personnel managers which manage the employees under the conflict situations.
Objectives : The study has three aims: 1) to assess the perceptions, attitudes, and behaviors of dental hygiene students and other college students towards oral and dental care, 2) to provide grounds for developing an oral and dental health educational program, and 3) to improve the oral and dental health status among the college student population. Methods : The subjects in this study were 520 students who included dental hygiene students from J health college and other majors from a four-year university located in Seoul. The survey was conducted from September, 2010, to June 3, 2011. The collected 507 questionnaires were analyzed. The collected data were analyzed by the statistical package SPSS WIN 12.0, and the level of significance was set at 0.05. Results : 1. As for a daily toothbrushing frequency, the largest number of the students brushed their teeth three times a day, and the dental hygiene students did that more often than the other majors(p<0.001). Concerning awareness of the toothbrushing method and the time for the change of the toothbrush, the rolling method was more prevailing among the dental hygiene students than the others(p<0.001). 2. In regard to education experience about the toothbrushing method and satisfaction with the existing toothbrushing method, 64.7% of respondents ever received education about the toothbrushing method(p<0.001). 3. As to scaling experience and gingival bleeding, the dental hygiene students had more scaling experiences(p<0.001), and the other majors who underwent gingival bleeding from time to time outnumbered the dental hygiene students who did(p<0.01). 4. In relation to subjective oral health status, the dental hygiene students found themselves to be in better oral health than the other majors(p<0.001), and the latter had more parts of the mouth in which they didn't feel well than the former(p<0.01). The dental hygiene students were more concerned about their oral health(p<0.001) and felt more uncomfortable in chewing(p<0.05). The other majors felt more uncomfortable in pronunciation(p<0.01). Conclusions : The results of this study indicated that dental hygiene students strongly recognized the importance of knowledge, motivation, and self-care behaviors, and attitudes towards oral health and dental care compared to other college students. It suggested that regular educational programs for the college student population should be implemented to increase their concern for oral and dental issues and to improve their oral and dental health status.
The purpose of this study was to confirm the degree of other behaviors among university students in the department of radiology(science) who experienced online classes in the COVID-19 situation and to investigate the effect of self-directed learning ability, flow and academic achievement on other behaviors. The research method was descriptive research. Data were 200 students collected from June 1 to 30 in 2022 using structured questionnaires as students in the Department of Radiology(science). Collected data were analyzed using descriptive statistics, t-test, ANOVA, Cronbach's pearson's correlation, multiple regression analysis with SPSS/WIN 21.0. The result of the study showed that the other behaviors were in the order of 'having s different thought, and 'sending text messages'. other behaviors was 1.75, self-directed learning ability was 3.60, flow was 3.23 and academic achievement was 4.29. There was a significant negative correlation between other behaviors and self-directed learning ability, flow, academic achievement. Factors influencing other behaviors were academic achievement, age, flow, self-directed learning ability in that order. As a result of the above research. it is expected that specific measures and various teaching methods to be flowed in the class are need as the way to lower the other behaviors of university students in the Department of Radiology(science) is to increase academic achievement.
To investigate the visual and extra-ocular photoreception, we cloned the opsin genes in ayu (Plecoglossus allivelis). Amplified fragments encoding exon-4 (-5) of opsin cDNAs were cloned from the retina and brains of ayu, and sequenced. One clone was identified as rod (AYU-Rh), two as green cone (AYU-GI, -G2), one as red cone (A YU-R), two as ultraviolet cone (AYU-UVl, UV2), one as VA (AYU-VA), and one as extra-ocular rod (AYU-ExoRh) opsins. 335 amino acids sequence deduced from the full-length cDNA of AYU-Rh showed high identity with that of other fish. Southern blotting analysis indicated that ayu possess two 'rhodopsin' genes, one is visual rhodopsin and the other is non-visual extra-ocular rhodopsin. In situ hybridization showed that the mRNA of AYU-Rh was localized only in rod cells in the retina. On the other hands, AYU-ExoRh was expressed only in the pineal. We cloned two isoforms (AYU-VAM and -VAL) of VA opsin from ayu. The deduced amino acid sequences of these variants were identical to each other within the first 342 residues, but they showed divergence in the C-terminal sequence. AYU- VAL corresponded to the long isoform found in other fish, and AYU-VAM was identified as a new type of VA opsin variant. Pal-VAM is a new probably functional non-visual photoreceptive molecule in fish.
Physicochemical characteristics and analysis of functional constituents of mulberry (Morus alba L.) fruit juices were investigated according to four different mulberry cultivars, including iksuppong, daeseongppong, cheongilppong and kwasangppong. Among the four mulberry cultivars examined, the small-sized cheongilppong had higher soluble solid content and lower titratable acidity, whereas the big-sized daeseongppong had higher titratable acidity and lower soluble solid content than other mulberry cultivars. Cheongilppong had higher contents of fructose and glucose, while daeseongppong had higher contents of citric and malic acids than the other mulberry cultivars. Kwasangppong had higher contents of two anthocyanins, cyanidin 3-glucoside and cyanidin 3-rutinoside, while cheongilppong had lower contents of two anthocyanins than the other mulberry cultivars. Daeseongppong had higher contents of resveratrols, flavonoids and moracin, whereas cheongilppong had higher levels of protocatechuic, chlorogenic and caffeic acids than the other mulberry fruits. Of the four mulberry cultivars, daeseongppong and cheongilppong had higher contents of GABA and DNJ, respectively, than the other mulberry cultivars. These results provide useful information to food technologists for the development and standardization of high quality mulberry juices as well as their processed foods.
Nine species of genus Ganoderma different in cultural characteristics each other were separated by histo-anatomical differences. Differences among the species and geographic distribution of G. lucidum were also analyzed to provide the criteria for the classification of Korean cultivation or wild type strains. Korean cultivation and wild type strains were quiet different from other species as well as Taiwan and North American G. lucidum strains in histo-anatomical traits of Ganoderma. Pore color of Korean G. lucidum strains was less brown than those of Taiwan and North American strains. Shapes of pores were round or circular in Korean strains but ellipsoidal or angular in Taiwan or North American strains. Pore numbers of Korean strains were more than those($4{\sim}6/mm$) of Taiwan or North American strains. Hardness of the pileus of Korean strains was much more than that of Taiwan or North American strains. Such characteristics of Korean strains were different from those of other species of Ganoderma. Korean G. lucidum strains could be classified into the other group because they had many different traits in growth characteristics of fruiting bodies and histo-anatomical characteristics from those of Taiwan or North American G. lucidum and other species of G. lucidum complex.

The purpose of this study is to help understanding of Korean fashion image by studying of design factor and formative characteristic. The methods of this study are the study of academic literatures as well as practical study through the analysis of case studies about actual works. The summary of this study's results is like followings. First, Perspectives seeing formative characteristic on Korean fashion image are Shape with a line, color, material, pattern, accessories. Second, Design factors deciding Korean fashion image are pattern, then in order of shape, color, material, accessories. Third, In results on design factor deciding Korean fashion image, when fashion designers focus on pattern, pattern is focused on without regard for other design factor. But color and material are accompanied by other design factor in expressing Korean fashion image. As fashion design point expressing Korean astetic, use of pattern is minimized other design factor, color and material are used with other design factor, then Korean fashion image will come out more than other time else. If We develop Korean fashion design to concentrate on shape and pattern, Korean fashion culture will be known to world people and beautiful value of Korean fashion will be handed effectively.
This study was conducted to investigate the possibility for low fat press ham which was made without fat added. Four kinds of press ham were prepared ; Apork 70%, fat 0% ; low fat press ham), B(pork 60%, fat 10%), C(pork 55%, fat 15%) and D(pork 50%, fat 20%). The press ham samples were stored at 4$\pm$2$^{\circ}C$. The physic chemical properties of press hams were analyzed during storage 60 days at 4$^{\circ}C$. The contents of moisture(71.3%) and crude protein (23.4%) of low press ham were higher than those of other products, and crude fat content (2.8%) was remarkably lower(p<0.5). The water holding capacity of press ham was higher than other products. Hunter's L(61.6) and b-value(5.9) of low fat press ham were lower than other products, but a-value(11.7) was higher. Hardness (70.2 dyne/cm), springiness(85%), chewiness(0.49kg), gumminess (2.0kg) and brittleness (0.7kg) of low fat press ham were higher than those of other products, but cohesiveness was lower than D product. Aroma and texture of low fat press ham were inferior to other, but taste and palatability of that were superor.
This study was performed to investigate the influence of dietary fiber, which from whole food on the serum lipid level and bowel function in rats. The fiber sources of experimental diets were prepared by drying and milling of small water dropwort(WD), mugwort(MW), butterbur(BB) and apple(AP). Each fiber sources was mixed at the 15% level of the diet. The level of dietary fiber in WD, MW, BB diets was similar but that in AP diet was slightly low. Male rats of Sprague-Dawley strain were blocked into 5 groups ; WD, MW, BB, AP, FF(fiber free). The animals were fed ad libitum each of experimental diets for 37 days. Food intake of AP and FF groups were than other groups, FF group was lower than other grous in food efficiency ratio. MW group showed highest level in fecal weight and fecal water content and group has the longest transit time compare to other groups. Serum triglyceride level was not significantly different among groups. BB group showed the lowest level in the serum total cholesterol. WD and MW groups showed slightly higher level in the serum HDL cholesterol than other groups. Mucosa weight was not significantly different among groups. The activity of maltase in mucosa of small intestine was highest in FF groups. Absorption rates of calcium were not significantly different among groups. Absorption rate of magnesium was higher in FF group compare to others. And, absorption rates of phosphorus in MW and FF groups were slightly lower than other groups.
