Presently Sasang constitutional medicine draws public attention and a diet based on this theory in gaining popularity. However, scientific data are not available to probe the effects of constitutional diet and the correlations between constitution and food consumptions. Thiry-four healthy subjects[26 females and 8 males] with Tae-eum(females: 5, males: 7), So-yang(females: 9)and So-eum(females: 12, males: 1), were studied. Subjects were not told the kind of constitutional diets they were consuming. Tae-eum constitutional diet was given to all subjects more than 2 meals a day for 8 weeks. The Sasang constitutional classification, food frequency questionnaire and food habits were assessed. The anthropometric assessment, dietary assessment, health status assessment and blood analysis were carried out before and after taking the Tae-eum constitution diet. In case of females, the body weights and BMI were different among the constitutional groups in the following order : Tae-eum constitutional diet. In case of females, the body weights the body weights and BMI were different among the constitutional groups in the following order: Tae-eum>So-yang>So-eum. In case of males, the body weights and BMI of Tae-eum were significantly higher than those of So-eum. In general, habitual food consumption of all of these four groups were very close to those for each of Sasang constitutional types described by Sasang medicine. After 8-weeks of Tae-eum diet, the health status and blood biochemical parameters were not significantly changed.

The application of laparoscopic techniques for the surgical management of Hirschsprung's disease is the recent trend. We described the surgical technique and postoperative long-term outcomes of the one-stage, laparoscopic-assiseted endorectal pull-through operation for Hirschsprung's disease. The technique uses three to four small abdominal ports. Laparoscopic mobilization of the sigmoid colon and rectum is performed and marginal artery-preserving colon pedicle is prepared. The rectal mobilization is performed using a transanal endorectal sleeve technique. The anastomosis is performed 0.5~1 cm above the dentate line. The age at surgery ranged from 6 days to 4 years. The average operative time was 144 minutes. Almost all of the patients passed stool and flatus within 36 hours of surgery. The average hospital stay after surgery was 6.5 days. Among 42 patients, 32 patients older than 3 years old were evaluated for function on defecation. All 32 patients have been continent, of those who needed laxatives were 11 (34.3%) due to constipation and overflow incontinence. Four children (12.5%) have remained dependent on laxatives. Laparoscopic-assisted endorectal pull-through operation for Hirschsprung's disease appears to be safe, provides the less pain, shorter time to full feeding, shorter hospital stay, and excellent cosmetic outcomes. Helping patients and parents ensure the quality of life, they should be provided with counseling, education, and longer-term follow-up care.

The purpose of this study is to understand consumer needs through emotion on character T-shirts. Study results suggest the basis for planning effective designs of character T-shirts. The results were summarized as follows: Emotion factors such as complex and arousal occupied 64.0% of the total. The types of the character T-shirts were clustered as four groups. The four types showed significant differences in all emotion factors. Complex emotion indicated its highest and lowest scores in types 4 and 2, respectively; and arousal emotion in types 2 and 3, respectively. As for the relation of consumption sensibility to emotions, three consumption sensibilities were related to all eight emotional adjectives. In the demographical aspect of emotions and consumption sensibilities, significant differences were found in age, gender, job and education. Therefore, the results of this study can be used as criteria improving emotions and consumption sensibility of character T-shirts. Especially, enhanced comsumption sensibility can be expected by the elimination of texts and the use of preferred character actions and vivid warm colors.

The purpose of the present research was to study (1) children's sex-stereotyped perception toward adult occupations, and (2) the impact of traditional sex-stereotypes on future occupational preference. The subjects of this study were 120 children, 3 to 8 years of age enrolled in kindergatens and elementary schools. The instrument was developed by the researcher and consisted of 10 occupations which are traditionally sex-typed in Korean society. 5 male and female sex-typed occupations were selected with the participation of 200 college students. These occupations were illustrated on 10 pictorial cards, and short verbal explanations were given for each of them. It was found that: (1) Levels of children's perception of occupational sex stereotypes show that children aged five to six are marked comparatively higher than those aged three to four in the perception of occupation, children of seven to eight age indicate slightly downward; however, they are not differed significantly from those of five to six. (2) As far as levels of children'5 perception of occupational sex stereotypes aged three to four, five to six and seven to eight are concerned, interaction between age and sex was not shown significantly. Female children were more stereotyped at almost all age levels. (3) Irrespective of sex and age, all subjects were more familiar with male than with female occupations. (4) in the choice of future occupations, boys as well as girls preferred sex-stereotyped occupations for themselves. Boy's choices were more stereotyped than girls', but the number of kinds of occupations chosen by boys and by girls was not different. (5) There was an increase with age in the number of children who gave future occupational choices.

The species composition and distributions of benthic marine plants on the East Coast of Korea were studied. We examined all species found in the intertidal and subtidal zones at four sites seasonally from August 2006 to May 2009. Of the 148 species identified, 92 were rhodophytes, 39 were phaeophytes, 16 were chlorophytes, and 1 was a seagrass. The most species (125) were found at Jukbyeon, while the fewest (99) were found at Chuksan. Overall, the numbers of species were highest during the spring and lowest in autumn. Seventy-five species (50 rhodophytes, 15 phaeophytes, 9 chlorophytes, and 1 seagrass) were found at all four sites. The dominant species providing cover were melobesioidean algae, Sargassum spp., Phyllospadix japonica, and Corallina pilulifera. The vertical distribution of benthic marine plants was characterized by C. pilulifera, Sargassum spp., Hizikia fusiformis, Grateloupia elliptica, Symphyocladia latiuscula, Grateloupia lanceolata, Ulva pertusa, and Chondria crassicaulis in the intertidal zone; Sargassum spp., P. japonica, Prionitis cornea, C. pilulifera, and Acrosorium polyneurum at 1 m depth; Sargassum spp., P. japonica, and melobesioidean algae at 5 m depth; and melobesioidean algae at 10 m depth. There was variation among the sites, presumably due to differences in the local conditions.

Two experiments were conducted to investigate the effects of feeding single or combined probiotics on performance and intestinal microflora of broiler chicks for five weeks. Diets based on corn and soybean meal contained 21.50, 19.0% CP and 3,100, 3,150 kcal/kg ME for starting and finishing period, respectively. Lactobacillus salvarius isolated from chicks intestine(LSC), Lactobacillus salvarius isolated from piglet(LSP) Bacillus polyfermenticus(BP) were fed with alone and mixed ones at the level of 0.21 and 0.1% in experiment 1 and 2. Three hundred eighty four chicks were randomly assigned to eight treatment with four replicates of 12 chicks each per treatment. Weight gain, feed consumption, feed conversion ratio(FCR) were weekly measured for 5 weeks. The number of intestinal microflora was examined at the end of experiment. There were no significant different weight gain of all treatment in both experiments. Feed consumption were not shown consistency. Chicks fed LSC alone showed the lowest feed conversion ratio of all treatment in experiment 1, but was not consistency in experiment 2. The number of Lactobacillus spp. tended to increase in chicks ileum fed probiotics treatments, whereas it was not consistency in cecum. The number of ileal E. coli was not decreased in BP treatment.

Four proteolytic bacteria were isolated and identified from a rotating biological contactor based on Bacillus. The four isolates, Ni 26, 36, 39 and 49 were identified as B. vallismortis, B. subtilis, Aeromonas hydrophila and B. amyioliquefaciens, respectively, based on their biochemical properties and 16S rDNA sequence analyses. The optimal proteolytic activity was observed in the temperature and pH ranges of 40-70$^{\circ}C$ and 8.0-8.5, respectively. The proteolytic activities of all the isolates were partially inhibited by phenylmethylsulfonylfluoride (PMSF), and the isolates Ni 26, Ni 39 and Ni 49 were inhibited by the metalloprotease inhibitor, 1,10-phenanthroline. Zymographic analyses of the culture supernatants revealed the presence of at least two pretenses in all isolates.

The main purpose of this study was to determine the influence of brand and country-of-origin on consumers' perception of apparel products. $2\times2$ between subjects factorial design with brand (no brand vs. prestigious brand) and country-of-origin (Italy vs. Korea) was used. Consumer ethnocentrism and product involvement were included as covariates in analyzing the data. The stimuus was a double-breasted v-neckline beige jacket. All the labels were removed and a label indicating one of the four brand/country-of-origin conditions was attached. The participants' perception of the jacket was measured in terms of product attitude, product evaluation, purchase intention and expected price. A total of 205 housewives participated in the field experiments conducted in front of four moi or department stores in Seoul, and 202 responses were used in the final analysis. There was no significant difference in product attitude, product evaluation and purchase intention according to brand or country-of-origin. But brand, country-of-origin and the interaction between the variables were significant in explaining the differences in expected price. Consumer ethnocentrism was significant in all the models, while product involvement was significant only in the case of product evaluation. The relationships among demographic variables, consumer ethnocentrism and product involvement were also examined.

To investigate the relationship between muscle fiber characteristics and meat quality traits by age of Korean native black goat (KNBG), four muscles (longissimus dorsi, LD; psoas major, PM; semimembranosus, SM; gluteus medius, GM) were obtained from five adult goat (AG; 18 months old) and five young goat (YG; 9 months old). PM muscle had the highest fiber number percentage (FNP) and fiber area percentage (FAP) of type I, followed by SM, GM, and LD muscles. FNP and FAP of type IIB were significantly (p<0.001) higher in AG than those in YG. YG had higher L^* values but lower b^* values than AG. The highest L^* and b^* values were observed in LD muscle (p<0.001). Age and muscle type had detrimental (p<0.001) effect on shear force and collagen content for all muscle in AG as compared to YG. YG had significantly (p<0.001) higher myofibrillar fragmentation index (MFI) than AG for all four muscles. These results suggest that muscle fiber compositions of different muscle types of KNBG depend on age, resulting in variations of meat color, MFI, collagen content, and shear force.

Background: Weakness of the abdominal and mid thoracic muscles the lead to thoracic kyphosis of stroke patients. The trunk muscles activity of stroke patients is significantly related to upper extremity. Objectives: To investigate the effect of seated exercise of thoracic and abdominal muscles on upper extremity function and trunk muscles activity in stroke patients. Design: One-group pretest-posttest design. Methods: A total of 27 stroke patients were recruited. All stroke patient were given seated abdominal exercise (posterior pelvic tilt exercises) and thoracic exercise (postural-correction exercise). All exercises were conducted for 30 minutes, three times a week for four weeks. The manual function test (MFT) and electromyography (EMG) were measured, and EMG electrodes were attached to thoracic paraspinal muscles and lower rectus abdominal muscles. EMG signal is expressed as %RVC (reference voluntary contraction). Results: Experimental group showed significant increases in abdominal muscles, paraspinal muscles activity and MFT total score, items of arm motion (forward elevation of the upper extremity, lateral elevation of the upper extremity, touch the occiput with the palm) in MFT after four weeks. Conclusion: These results suggest that, in stroke patients, seated exercise of thoracic and abdominal muscles contribute to improve trunk muscles activity and upper extremity function in stroke patients.
