This study was conducted to examine the growth change in external nose according to age which plays an important role in determining the facial profile, by analysing the biennial serial lateral cephalograms of 20 males and 20 females of mean 8.5 years old to 16.5 years old who have a normal occlusion. The results of this study were summarized as follows. $\cdot$ Both mean and standard deviation were obtained according to each item, sex and age for the male and female. $\cdot$ Nose heights of the male and female increased with increase in their age. The upper to lower nose height ratio somewhat decreased for both male and female with increase of age. The mean ratio was 3.69 : 1 for the male, respectively, and 3.83 : 1 for the female during this study.$\cdot$ The nose depth indicated the most significant increase of all items according to the increase of age, while the sagittal depth inicated higher value for the female than that of the male in the most age groups. $\cdot$ The nose inclination did not show a remarkable change during this study. $\cdot$ The proportions of growth completed at the earliest age showed the highest percentage for sagittal depth(male : $87.14\%$ & female : $91.29\%$). Also, the male indicated the lowest percentage in lower nose height $(73.04\%)$, while the female did the lowest in nose depth$(79.09\%)$. $\cdot$ There was shown the variable of the greatest correlation between the upper nose inclination and nose depth. $\cdot$ From this study, the whole external nasal growth was occurred downward and forward which was more frequent for forward growth than vertical growth.

This study aims to assess the training effect of QFD(Quality Functional Deployment) program for 3 years over startups, adopted from the conventional QFD widely used in the large companies to break up to a sluggish sales and growth, for employees working in startup whether the participants in startup and venture company taking this lessons into their real tasks or not. In particular, the focus of this study falls on figuring out whether individual characteristics of the participants play a role in moderating effect over transfer intension factors and its link path structure. The research results drive out two significant findings. First, in terms of relationship between the influence of transfer intension by self-efficacy and the validity of training content with the learner's readiness, the moderating effect of demographic features of the participants is effective partially by the sex and fully by their working position, but not statistically significant by age, education, and the prior startup career. This research deliver the following significant implication that the active participation of CEO level, decision-maker guarantee the higher performance of the training program like QFD program, more stresses falling on practical implementation in real business rather than just ending up with career training. This study gives significant policy implication to quasi-government organization running all public startup training projects.

A total of 5,462 isolates suspicious of Salmonella, Shigella and E. coli which were isolated during 1983 to 1985 by 12 City Hygine Laboratories and General Hospital Laboratories were received and identified at the National Salmonella Center, Seoul, Korea. The result of identification of these strains were summarized as follows: 1. It was confirmed that the total organisms broke down into 2,014 strains of Salmonella 1,294 of which were S. typhi, 887 strains of Shigella and 2,561 strains of E. coli. 2. For seasonal distribution of enteric pathogens, July was the month with the highest out breaks of salmonellosis, May was the month of Shigellosis, and April was of the highest month it in the case of E. coli. 3. Salmonella typhi with the highest incidence of isolation was shown to belong to various phage types, especially with the strains detected in Seoul. M1 type was widely distributed all over the country, but the majority was E1 type in 1983. 4. For age distribution of patients, the 20-29 age group had the highest incidence of salmonellosis whileas the 1 to 9 age group had the highest incidence of Shigellosis. 5. For sexuly distribution of Salmonella and Shigella infections seemed to be relatively higher in the female than in the male. However, E. coli. had no relationship to both sex. 6. The antibiotic sensitivity patterns of S. typhi cultures showed a tendancy to be resistant to colistin, gentamycin, neomycin, tetracycline and streptomycin. 7. The isolates of S. paratyphi-A, S. typhimurium and S. enteritidis seemed to have a tendency of multiple drug resistance. 8. 93.9 percent of 1,568 E. coli strains showed negative reactions to the antisera of enteropathogenic E. coli and 15.6 percent of them produced a heat-labile enterotoxin, but positive reaction to the antisera was 6.1 percent and 11.6 percent of them producled the enterotoxin.

This study examined the mediating effects of the adult educator's characteristics on the relationship between the characteristics of the participants attending adult continuing education and the happiness index of lifelong learning, the motivation of participating in learning and the institution characteristics. The research results showed that there is no difference in the happiness index of lifelong learning according to the sex of the adult learners, education level, age, residence, participation experience of lifelong learning, occupation, and type of lifelong programming being participated. The characteristics of adult learners do not have a direct impact on the happiness index of lifelong learning. The characteristics of adult learners affect the characteristics of adult educators, motivation of participating in learning and institution characteristics. Although the characteristics of educators do not affect the happiness index of lifelong learning, the motivation of participating in learning and institution characteristics have a positive impact on the happiness index of lifelong learning. While the characteristics of adult educators do not have a mediating role for the characteristics of adult learners and happiness index of lifelong learning, the motivation of participating in learning and institution characteristics have shown a complete mediation for the characteristics of adult learners and the happiness index of lifelong learning. These findings suggest that the participating motivation of adult learners, adult educator's improved understanding on adult learners and education quality of education institution are very important for increasing the happiness index through a lifelong learning experience.
Uncoupling protein-1 (UCP-1) plays a major role in thermogenesis at brown adipose tissues and has been implicated in the pathogenesis of obesity and metabolic disorders. The purpose of this study was to estimate the effects of A-3826G polymorphism in 117 Korean prepubertal children aged 8-11 years olds. Anthropometry by bioelectrical impedance analysis method, plasma lipid profiles by auto-biochemical analyzer and UCP-1 genotyping by PCR-RFLP were done. The frequencies of UCP-1 genotypes were AA; 17.7%, AG; 57.8%, GG; 26.6%. The frequencies of each G allele (55.5%) was similar to Japanese's (49%) and higher than Caucacian's (25%). No correlation UCP-1 polymorphism and BMI (kg/$m^2$) or the degree of obesity described by the relative percentiles of the standard weight according to height in prepubertal children. However, plasma total- and LDL-cholesterol were significantly increased in G allele when sex, age and weight were adjusted. Our results suggested that G allele of UCP-1 gene was stronger risk factors in hyperLDLcholesterolemia than A allele. This impact might be progressed as the precaution against the revalence of obesity based-metabolic disease.
Purpose: Most terminally ill cancer patients die from cancer anorexia-cachexia syndrome. This study evaluated a prognostic role of plasma leptin levels in terminally ill cancer patients. Methods: This study enrolled 69 terminally ill cancer patients who were aged above 20 years old from July 2009 to July 2010. For univariate analysis, an association between leptin levels and patient's characteristics or other variables was examined using Spearman's correlation analysis, Wilcoxon's rank-sum test or Kruskal-Wallis test, as appropriately. For multivariable analysis, Cox's proportional hazard regression model was used to evaluate a clinical significance of plasma leptin levels as a prognostic factor and to determine factors which affect the risk of death in terminally ill cancer patients. Results: A statistically significant positive correlation between plasma leptin levels and survival time was found. Univariate Cox's proportional hazard regression analyses also showed a moderately significant association between plasma leptin levels and survival time. However, after adjusting variables for sex, white blood cell counts, total bilirubin, AST, ALT, albumin and CRP levels, plasma leptin levels were not significantly associated with survival time. Conclusion: No significant association was found between plasma leptin levels and survival time in terminally ill cancer patients. However, this study suggested a prognostic value of plasma leptin levels in gastrointestinal cancer patients.

Purpose: The importance of Helicobacter pylori eradication after endoscopic resection (ER) of gastric neoplasms remains controversial. In this study, we clarified the importance of H. pylori eradication for metachronous lesions after ER. Materials and Methods: This study included 3,882 patients with gastric neoplasms who underwent ER. We included patients infected with H. pylori who received eradication therapy. Among them, 34 patients with metachronous lesions after ER and 102 age- and sex-matched patients (nonmetachronous group) were enrolled. Background mucosal pathologies such as atrophy and intestinal metaplasia (IM) were evaluated endoscopically. The expression levels of CDX1, CDX2, Sonic hedgehog (SHH), and SOX2 were evaluated based on H. pylori eradication and the development of metachronous lesions. Results: The eradication failure rate was higher in the metachronous group than in the nonmetachronous group (P=0.036). Open-type atrophy (P=0.003) and moderate-to-severe IM (P=0.001) occurred more frequently in the metachronous group. In patients with an initial diagnosis of dysplasia, the eradication failure rate was higher in the metachronous group than in the nonmetachronous group (P=0.002). In addition, open-type atrophy was more frequent in the metachronous group (P=0.047). In patients with an initial diagnosis of carcinoma, moderate-to-severe IM occurred more frequently in the metachronous group (P=0.003); however, the eradication failure rate was not significantly different between the two groups. SHH and SOX2 expression was increased, and CDX2 expression was decreased in the nonmetachronous group after eradication (P<0.05). Conclusions: Open-type atrophy, moderate-to-severe IM, and H. pylori eradication failure were significantly associated with metachronous lesions. However, eradication failure was significantly associated with dysplasia, but not carcinoma, in the metachronous group. Thus, H. pylori eradication may play an important role in preventing metachronous lesions after ER for precancerous lesions before carcinomatous transformation.

In this study, with the problem of "What is the desirable illustrations?", the problem points of the existing textbooks were analyzed, and the opinions of experts concerning desirable illustrations were examined through questionaire survey, and by developing 'Analysis Framework of Illustrations', and Korean-Japanese 'science' textbooks were analyzed and compared with. The conclusions for the direction of korean 'science' textbooks are summarized as follows : 1) The numbers of korean illustrations should be more about two than one of per one page of the existing textbooks. 2) The korean illustrations for the 6th grade should be more largely inserted. 3) The more econmic space utilizing measure should be groped for looking at from the such side. 4) Though the kinds of Korean illustrations are mostly composed of photographs, pictures, illustrations, cartoons, etc. should be positively utilized. and the shapes of photographs should be diversified by such as square, round shape,omissions of background and others. 5) The distribution of players by sex should be considered envenly for male and female from the ascendency of male (1.5: 1). 6) It was found that it is desirable for the formation of role of illustrations of 20% for motive inducement, 45% for guidance for experimentation, 30% for presentation of data, and 5% for presentation of the results of experimentation. 7) The illustrations for guidance for experimentation should present important stages of experimentation process regardless the number of illustration. 8) It would be advantageous for motive induction to find the subject matters as possible as from the children's close actual life. 9) It is necessary to induce more freely method in utilizing Printing plate for inserting illustrations. 10) It is the result of research that the existing Korean textbooks are not suitable in inducing interest, and the positive strategy to induce interest is demanded. 11) It is required to select their location freely in accordance with the content regardless the. 12) In order to develop such illustrations, it is required to cultivate expert illustrators, and more economic investment is required for development of illustrations. The emphasis matters of revision of the 6th educational process of 'Inducement of study motive and emphasis on interest' is the change of presenting form and method of illustrations, which is expected to be rewarded with much good fruits.
Objective: The purpose of this study is to explain the effect and reciprocal action among tumor necrosis factor (TNF) like weak inducer of apoptosis (TWEAK), fibroblast growth factor-inducible 14 (Fn14), and transforming growth factor-$\beta1$ (TGF-$\beta1$) on degeneration of human intervertebral disc (IVD). Methods: Human intervertebral disc tissues and cells were cultured with Dulbecco's Modified Eagle's Medium/Nutrient F-12 Ham (DMEM/F-12) media in $37^{\circ}C$, 5% $CO_2$ incubator. When IVD tissues were cultured with TWEAK, Fn14 that is an antagonistic receptor for TWEAK and TGF-$\beta1$, the level of sulfated glycosaminoglycan (sGAG) was estimated by dimethyl methyleneblue (DMMB) assay and sex determining region Y (SRY)-box 9 (Sox9) and versican messenger ribonucleic acid (mRNA) levels were estimated by reverse transcriptase polymerase chain reaction (RT-PCR). Results: When human IVD tissue was cultured for nine days, the sGAG content was elevated in proportion to culture duration. The sGAG was decreased significantly by TWEAK 100 ng/mL, however, Fn14 500 ng/mL did not change the sGAG production of IVD tissue. The Fn14 increased versican and Sox9 mRNA levels decreased with TWEAK in IVD tissue TGF-$\beta1$ 20 ng/mL elevated the sGAG concentration 40% more than control. The sGAG amount decreased with TWEAK was increased with Fn14 or TGF-$\beta1$ but the result was insignificant statistically. TGF-$\beta1$ increased the Sox9 mRNA expression to 180% compared to control group in IVD tissue. Sox9 and versican mRNA levels decreased by TWEAK were increased with TGF-$\beta1$ in primary cultured IVD cells, however, Fn14 did not show increasing effect on Sox9 and versican. Conclusion: This study suggests that TWEAK would act a role in intervertebral disc degeneration through decreasing sGAG and the mRNA level of versican and Sox9.

The purpose of this study was to identify levels of activity of daily living, self-efficacy. stroke specific quality of life and need for self-help management program for patients with hemiplegia in the home. Data were collected from June to November, 2000 and subjects were 88 poststroke patients who lived in Seoul and Kyunggi-do. The questionnaire consisted of 5 scales: activities of daily living, self-efficacy, stroke specific qulaity of life and need for a self-help management program. Data were analyzed using frequencies, percent, paired t-test, and Pearson's correlation coefficient with the SAS(version 6.12) program. The results are as follows ; 1) Most of subjects were Partially independent in ADL, but they needed assist once to do dressing, bathing meal preparation and house keeping work. 2) The mean self-efficacy score was 54.89(range : 1 to 80) and the individual differences were large. 3) Subjects responded that they were satisfied on the stroke specific quality of life scale totaled 65.8%. This value is comparatively low, especially for social role(51.4%), family functioning(58.3%) and mood (62.2%). 4) The highest needs for self-help management programs were for physical therapy, stress management, and range of motion exercise and the lowest needs were for elimination management and training, family counseling, and speech therapy. 5) On the demographic variables, sex showed significant differences for the dependent variables. Females had higher scores than males for IADL, self-efficacy, stroke-specific quality of life, and need for self-help management. 6) Age had high negative correlation with ADL, self-efficacy and stroke specific quality of life. Age was also correlated with need for self-help management. In conclusion, there was a high correlation for ADL, Self-efficacy and Quality of life in poststroke patients of home. The patient with a stroke also had a strong need for self-help management programs especially physical therapy and stress management. Therefore rehabilitation programs based on self-efficacy enhancement need to be developed in order to promote independent living for patients with hemiplegia.
