Objective: To evaluate the relative importance of bilabial prominence in relation to other facial profile parameters in a normal population. Methods: Profile stimulus images of 38 individuals (28 female and 10 male; ages 19-25 years) were shown to an unrelated group of first-year students (n = 42; ages 18-24 years). The images were individually viewed on a 17-inch monitor. The observers received standardized instructions before viewing. A six-question questionnaire was completed using a Likert-type scale. The responses were analyzed by ordered logistic regression to identify associations between profile characteristics and observer preferences. The Bayesian Information Criterion was used to select variables that explained observer preferences most accurately. Results: Nasal, bilabial, and chin prominences; the nasofrontal angle; and lip curls had the greatest effect on overall profile attractiveness perceptions. The lip-chin-throat angle and upper lip curl had the greatest effect on forehead prominence perceptions. The bilabial prominence, nasolabial angle (particularly the lower component), and mentolabial angle had the greatest effect on nasal prominence perceptions. The bilabial prominence, nasolabial angle, chin prominence, and submental length had the greatest effect on lip prominence perceptions. The bilabial prominence, nasolabial angle, mentolabial angle, and submental length had the greatest effect on chin prominence perceptions. Conclusions: More prominent lips, within normal limits, may be considered more attractive in the profile view. Profile parameters have a greater influence on their neighboring aesthetic units but indirectly influence related profile parameters, endorsing the importance of achieving an aesthetic balance between relative prominences of all aesthetic units of the facial profile.

Glenohumeral internal and external rotation with shoulder abducted in the frontal plane often causes impingement of the supraspinatus tendon. whereas similar activity in scapular plane does not cause impingement. The Purpose of this study was to determine if assessment among the three positions as 30 degrees, 60 degrees, 90 degrees abduction in the sitting position of the scapular plane could be affected the comparison between intemal and external peak torque, total work, average power. In this study, Isokinetic shoulder rotational strength was evaluated in twenty healthy male university students, using the Cybex NORMTM System (CYBEX Division of LUMEX, Inc., Ronkonkoma, New York). Test data was gathered in the plane of the scapular, 30 degrees of horizontal flexion anterior to coronal plane, and the subjects performed the test with the arm 30, 60, and 90degrees abducted in the sitting position. also, test speed was set at deg/sec. Statistical analysis was performed using SPSS 7.5 for Windows software and mean and standard deviations were calculated. ANOVA was used to analyze the difference of the values in the three test positions. A paired t-test was used of examining the difference in the means peak torque between external and internal rotation. Not any significant difference was found among three abduction positions in scapular plane, even though there was a consistent pattern of greater strength in the abducted position of 60 degrees. Internal relation strength peak torque and total work were greater than those of external rotation in every test positions.

This study was carried out to investigate correlation with food preference of subjects in three constitution groups on the view point of constitutional medicine. The constitutions of 124 college students(male 80, female 44) was classified by QSCC II method. Food preference of the subjects was surveyed in accordance with suggested foods for each constitution and was analyzed using Hedonic scale. The distribution of the constitutional revealed that Soeum individuals accounts 53%, followed by ; Soyang 19%, Taeum 28%. For men, sorghum, potatoes, beef, scombroid, oyster, saury, octopus, codfish, walleye pollack, shrimp, croaker, pineapple, eggplant, leek, pumpkin, toenjang, draft beer, diluted liquor, coffee, cocoa were statistically different in food preference score by sasang constitution(p<0.05). For woman, chicken, pollack roe, a walleye pollack, persimmon, jujube, melon, citron, celery, burdock, vinegar, bean-paste soup, draft beer, ginseng, honey were statistically different in food preference score by sasang constitution(p<0.05). Association of sasang constitutions and food thought to be harmful or healthy to each constitution was analyzed. But Food preference score of food thought to be harmful or healthy were not statistically different in score among sasang constitutions. This results suggested that food intake patterns of subjects were associated with sasang constitutional food in parts.

The purpose of this study was to investigate the difference of the morphological diagram by Sasang Constitutions and compare with Huh's morphological diagram, a theory based on the Four Cho Theory(四焦設) by Lee Je-Ma. We classified the Sasang Constitutions of 104 Korean College Students(average age 23.81) using QSCC II. Before measuring of morphologic diagrams, we exert the subjects to take supine position on the bed, and make it a rule that our staffs mesure each people directly. The 50% of the total subjects was Soeumin, 26.9% was Soyangin and 23.1% was Taeumin, our study shows the higher percentage than the other studies in Soeumin. The results as follows ; In the cases of man, Taeumin have more developed Low-Middle Cho(the interval between stomach line and Navel line) than other constitutions, whereas Soeumin has more developed Low cho(the interval between Navel line and Ilium line). In the cases of woman, there is no significant difference of Huh's morphology diagram among three Sasang constitutions. We analyzed the difference of obesity among sasang constitutions, and we found that the BMI(Body Mass Index$(Kg/m^2)$) of Taeumin was significantly higher than other constitutions in male. But there was no significant difference among Sasang constitutions in female. We have not found the exact accordance between the real measurement and Huh's Theory. But for man, there are several statistically significant results, indicating the usefulness of the Huh's Morphological Diagramming theory on the discriminating ability of Sasang Constitutions Classificaton. So this results suggest that the use of the Huh's theory should be improved in the classification of the Sasang Constitutions, considering the difference of morphology by sex.

Objectives : The aim of this study was to investigate the effects of licorice supplementation on muscle injury, plasma cortisol, testosterone and insulin sensitivity after high intensity resistance exercise. Methods : The fourteen health college male students were voluntarily participated in this study and were randomly divided into 2 groups: Control group (CON, n=7), Licorice group (LR, n=7). LR group ingested 2 g/time of licorice extract (mixed with 100 ml of water) two times/day for 10 days while the CON group ingested 100 ml of water. All subjects performed a high intensity resistance exercise (half-squat, 8 RM at 80% one-repetition maximum, 5 sets, 1min rest). Blood samples were collect before (-7) and after (0) licorice supplementation, and then 1 day, 2 day and 3 day post exercise. After 10 day treatment, plasma creatine kinase, cortisol, testosterone, glucose, insulin were measured. To determine the insulin sensitivity, HOMA-IR was calculated. Results : Plasma creatine kinase activities were significantly elevated after exercise, but there was not different between two groups. The plasma cortisol and testosterone levels were not significantly different between two groups. Plasma glucose levels were increased at 1 day and 2 day after exercise in the LR comparing with CON group (P<0.05) but plasma insulin levels were significantly lower in comparison with CON. HOMA-IR were significantly lower in the LR than CON group at 0 day to 3 day (P<0.05). Conclusions : The results of the current study suggest that licorice supplementation for 10 days might not attenuate the high-intensity exercise-induce muscle injury but may enhance the whole-body insulin sensitivity.

This study was designed to investigate the effect of dandelion juice supplementation on attenuation of oxidative stress and hangover after drinking alcohol in healthy college male students. This human trial was conducted by two phase cross over design with two weeks wash out period. The subjects (age $24{\sim}28$ years) were volunteers who had more than 72 g of ethanol drinking capacity. Dandelion group was given dandelion juice 220 mL daily for 7 days. Biochemical markers were determined in blood samples taken at 0 and 150 minutes after administration 72 g of alcohol. The levels of plasma glutamic oxaloacetic transaminase, glutamic pyruvic transaminase, lactate dehydrogenase and bilirubin, the indicators of liver cell damage, were not significantly different between groups. No significant differences in lymphocyte DNA damage level between groups was observed. However, plasma acetaldehyde dehydrogenase (ALDH) and high density lipoprotein cholesterol levels were significantly (p<0.01) increased in dandelion supplemented group compared to that of control group. Furthermore, activities and protein expressions of glutathione-reductase and catalase of erythrocytes were significantly elevated in dandelion supplemented group compared to that of control group. From the above results, it is concluded that dandelion juice supplementation can reduce oxidative stress and hangover syndrome through the elevation of ALDH and antioxidative enzyme system in healthy male adults.

Recent increases of asthma and allergies in childhood made the need for a standardized approach to international and regional comparisons of their prevalence and severity. To address these issues, 'International Study of Asthma and Allergies in Childhood (ISAAC)' is currently underway. In Korea, 'Nationwide Study of Asthma and Allergies in Korean Children' began in 1995 according to ISAAC protocol. ISAAC written and video questionnaires were used in this survey, but their reliability and validity were not evaluated properly yet. In this study, our aim was to evaluate the reliability and validity of two kinds of questionnaires and their usefulness in international and regional comparisons. The test and retest of two questionniares were completed by male(n=110) and female(n=111) middle school students with two and three weeks interval each. Kappa(or weighted kappa) were calculated from each questions and validity coefficients were estimated from those statistics. In Korean version of written questionnaire, the questions for allergic rhinitis, atopic dermatitis, allergic conjunctivitis, and food allergy proved to have high kappa values (or weighted kappa values) and validity coefficients and they can be used in further studies without any correction. But some questions about asthma(especially nocturnal cough, wheezing in exercise, and severe asthma) and drug allergy need to be revised for better under-standing to study subjects. Video questionnaire has the same degree of reliability and validity when compared to written questionnaire and this is the unexpected result. Accordingly, it also need to be revised to overcome the racial and cultural differences of the study subjects. In conclusion, the Korean version of written and video questionnaires may be considered to be useful methods in international and regional comparisons of asthma and allergic diseases in childhood after correction of some questions.

The purpose of this study is to observe activation of limbic system during performing visuospatial tasks by 21% and 30% oxygen administration. Eight right handed male college students were selected as the subjects for this study. A visuospatial task was presented while brain images were scanned by a 3T fMRI system. The experiment consisted of two runs: one was a visuospatial task under normal air(21% oxygen) condition and the other under hyperoxic air(30% oxygen) condition. The neural activations were observed at the limbic system which is seperated 8 regions such as cingulate gyrus, thalamus, limbic lobe, hypothalamus, hippocampus, parahippocampa gyrus, amygdala, and mammiilary body. By two oxygen levels, activation areas of limbic system are almost identical. Increased neural activations were observed in the cingulate gyrus and thalamus with 30% oxygen administration compared to 21% oxygen. During 30% oxygen administration, improvement of visuospatial task performance has a relation to increase of neural activation of subcortical structures such as thalamus and cingulate gyrus as well as cerebral cortex.

Objective: Computers and smartphones have become a necessity for modern people, and the use of these things in an inappropriate position has increased the number of people who complain about neck problems. The purpose of this study was to compare the changes of cervical angle, range of motion (ROM) and pain threshold according to the McKenzie stretching and dry cupping therapy. Design: Cross-over design. Methods: We included 12 male and 6 female college students in their twenties, and conducted a pre- and post-test to evaluate the changes of each variable after the application of the McKenzie stretching and dry cupping therapy. Results: Neither the cervical spine angle nor the turtle neck angle showed any change in both the McKenzie stretching and the dry cupping treatment. In the McKenzie stretching, the pain threshold decreased, and the ROM of the cervical spine increased in all directions but there was no significant difference. The pain threshold was increased in the dry cupping treatment, and the ROM of the cervical spine was significantly increased in all directions (p<0.05). Comparisons of the McKenzie stretching and cupping treatment showed that the cupping treatment produced significantly greater pain thresholds and improvements in ROM of the cervical spine than the McKenzie stretching technique (p<0.05). Conclusions: Cupping treatment is more effective in improving ROM of the cervical spine and pain thresholds than the McKenzie stretching technique. In the future, cupping treatment will be one of the treatment options for pain and ROM impairments of the cervical spine.

The purpose of this study is to investigate the impact of college education satisfaction on the employment preparation and social participation of young adults during the pandemic period. To accomplish this research purpose, the researcher used the panel data of Korea Youth Policy Institute and analyzed the eight variables related to college education satisfaction, employment preparation, and social participation. This study's sample consisted of a total of 2,941 individuals, and both structural equation modeling and multigroup structural equation modeling were applied for the analysis. The results revealed that college education satisfaction had a significantly positive influence on the employment preparation activities and social participation of young adults. In the multigroup structural equation modeling analysis, it was found that college education satisfaction had a significantly positive impact on employment preparation and social participation for women, while for men, it only significantly affected employment preparation. Furthermore, college education satisfaction did not show significant effects on the employment preparation and social participation of graduates from junior colleges, but it did have a significantly positive impact on the employment preparation activities of graduates from four-year colleges. Based on these research findings, policy and educational interventions to enhance the college education satisfaction of male students and graduates from junior colleges are required.
