As foodservice industry has been developing, more people are interested in healthy life and want to learn cooking. This study validated the moderating effect of education program on cooking institutes. Also the present study revealed cause and effect relationship among the education environment, the satisfaction and reregistration intentions by conducting a survey for trainees in cooking institutes located in Busan and Gyeongnam area. For the purposes of the study, conjunction and organic cause-and-effect relationship of entire model was validated by using an exploratory factor analysis, confirmatory factor analysis and structural equation modeling with 313 trainees who have used cooking institutes. A nested model and basic model were established to analyze the moderating effect of education program. The adjustment role of education program was validated with ${\chi}^2$ difference considering the degree of freedom between two models. As results of the analysis, the education service was statistically significant in all factors except the effect on education satisfaction. The education program has moderating effect on the relationship between the level of instructor and satisfaction degree, and between satisfaction degree and the reregistration intentions. Therefore, this study suggests that managers of cooking institutes should recruit instructors with excellent capability in order to operate the education program very well.

The purpose of this study was to examine the influential relationship between the type of dental treatment and the dental fear of teens in a bid to seek ways of relieving adolescents of dental anxiety and fear. The subjects were teenaged students in South Gyeongsang Province. After a survey was conducted for eight days from December 2 to 9, 2009, the answer sheets from 420 students were analyzed. The findings of the study were as follows: When a correlation analysis was employed to look for connections between dental treatment experiences and dental fear, the components of dental treatment experiences had a significant correlation to those of dental fear. As a result of making a regression analysis, overall dental fear was under the significant influence of prosthodontic treatment experiences, and avoidance of dentistry was significantly affected by conservative treatment experiences. Oral and maxillofacial treatment experiences had a significant impact on physiologic response, and dental stimulus was significantly affected by prosthodontic treatment experiences. Therefore dental institutions should direct their efforts into the development of manuals geared toward different types of treatment and different patients in order for adolescents to receive dental treatment without any anxiety or fear, to get a regular dental checkup, to receive more preventive treatment, to promote their oral health and ultimately to lead a healthy life.

This research examines the constitutional meaning of the right to health through reviewing the decisions of the Constitutional Court and proposed amendment of the Constitution issued by the President. This article further discusses the relationship between the right to a humane livelihood and the right to health. Health is a fundamental freedom and inalienable human right which is a prerequisite to accomplish individual's independent activity and realization of value. Thus, the government is obligated to protect and uphold the right. Article 36(3) of the Constitution delineates the government's duty to protect and fulfill the right to health. Through the interpretation of both Article 36(3) and Article 34 of the Constitution, I suggest that the right to health implies 'the right to social security for health'. The Constitutional Court has narrowly interpreted the scope of the right to a humane livelihood by defining the term as "minimum material living standards". However, it should be interpreted as 'the right to enjoy a healthy and cultural life for human dignity' and setting the level of protection is solely on the discretion of the legislative branch. Ultimately, the judicial review on the right to a humane livelihood connects with the issue of rational control for legislative discretion.

To evaluate age and gender differences in the relation of cardiovascular risk factors, cognitive impairment, and subclinical carotid atherosclerosis from aged people using by a cross sectional method. Sixty-nine healthy elders living in the community who had not previously undergone carotid ultrasonography were included. We conducted life style surveys, and cognitive function tests including Korean-mini-mental state examination (K-MMSE) and clinical dementia rating-Korean. Various biomarkers from blood were assessed; fasting insulin-like growth factor-1, lipid-profile, high sensitivity C-reactive protein, total homocysteine, glucose, insulin, Homeostasis model assessment (HOMA) for insulin resistance index, vitamin B12, and folate level. Carotid intima-media thickness (C-IMT), and plaques were measured using carotid ultrasonography and aortic ultrasonography, a valid index of atherosclerosis. For the elderly subjects (aged 65-82 years), cognition impairment was more prevalent in females while subclinical atherosclerosis was more prevalentin males. Increased C-IMT has been kept in males, and C-IMT shows increasing trend and the peak at about 80 year-old in females with increasing age. The significant correlations between C-IMT and many vascular risk factors including age, triglyceride, abnormal homocysteinein male, and K-MMSE, insulin, HOMA index and abnormal aortic ultrasonography in female were different in each gender, with the exception of homocysteine (p<0.05). This data suggests that there were differences of age and gender characteristics in terms of subclinical atherosclerosis, cognitive impairment and vascular risk factors in community-living elders. Further larger and longitudinal studies across entire age are required to better understand the effects of risk factors on subclinical atherosclerosis.

Purpose : This study was performed to determine the rate of neonatal symptomatic spontaneous pneumothorax, and the corresponding clinical characteristics, co-morbidities, and outcomes. Methods : The demographic characteristics, clinical symptoms and signs, associated abnormalities, methods of treatment, and outcomes were investigated in 22 neonates with symptomatic spontaneous pneumothorax in the neonatal intensive care unit (NICU) of Chonnam University Hospital between March 2003 and February 2008. Results : The rate of spontaneous pneumothorax was 0.55%. Among the 22 neonates, the number of outborns was 15 (68.2%) and the number of males was 12 (54.5%). The main symptoms and signs were chest retraction, tachypnea, and cyanosis. The pneumothoraces were more frequent on the right side (59.1%) and all cases were diagnosed within 3 days of life. Four cases (18.2%) had urologic abnormalities and 7 cases (31.8%) had cranial abnormalities by ultrasonography. The treatments included oxygen (81.8%) and oxygen with chest tube drainage (18.2%). All of the infants survived and the overall outcomes were favorable. Conclusion : When respiratory symptoms and signs are develop abruptly in otherwise healthy newborns, the clinician should suspect a spontaneous pneumothorax and check a chest x-ray as soon as possible. Although the outcome of neonatal symptomatic spontaneous pneumothorax is favorable, renal and cranial ultrasonography are needed because of the higher possibility of urologic abnormalities and germinal matrix/intraventricular hemorrhage than in newborns without a pneumothorax.

To develop high value added healthy functional resource from Korean mulberry, the bioactive compounds and antioxidant activities of three different mulberry cultivars were investigated and compared with blueberry and strawberry. Total phenolics, total flavonoids, and trans-resveratrol of 'Daesungppong' were the highest than the 'Suwonppong', whereas those of the strawberries were the lowest. In case of total anthocyanins, 'Daesungppong' was also the highest and followed by blueberry. The antioxidant activities of 'Daesungppong' using DPPH (2,2-diphenyl-1-picrylhydrazyl), ABTS (2,2'-azinobis-(3-ethylbenzothiazoline-6-sulphonic acid), and FRAP (Ferric reducing antioxidant power) assays were the highest followed by 'Suwonppong'. Meanwhile, there were no significant differences in the antioxidant activities between 'Cheongilppong' and blueberry, and the activities of strawberry were the lowest. Furthermore, there was a strong correlation (r = 0.764-0.897) between DPPH, ABTS, and FRAP assays with the bioactive compounds such as total phenolics, total flavonoids, and total anthocyanins. Therefore, Korean mulberry, especially 'Daesungppong' demonstrated interesting biological properties that suggest its use as a potential source and high value added of natural antioxidant compounds and antioxidant activity.

Propionic acidemia (PA) is an autosomal recessively inherited disorder of the organic acid metabolism. It is caused by a deficiency of propionyl-CoA carboxylase (PCC). PCC is a heteropolymeric enzyme composed of ${\alpha}$- and ${\beta}$-subunits. The clinical symptoms of PA are heterogeneous and present vomiting, dehydration, hypotonia, and lethargy, and it can result in death. The typical presentations of neonatal onset PA are life-threatening metabolic acidosis and hyperammonemia. Here, we described a case of neonatal onset PA with mild clinical presentations. She was born to a healthy mother without complications. No significant illness was observed until nine days after birth. She started exhibiting poor oral feeding, vomiting, lethargy, and hypotonia at ten days old. Her laboratory results showed mild hyperammonemia and acidosis. The initial diagnosis was neonatal sepsis and she was treated with antibiotics. However, her clinical symptoms didn't improve. So we considered a metabolic disease. She was given nothing by mouth and intravenous hydration and nutrition support was performed. Propionylglycine and 3-hydroxypropionic acid were showed high concentrations in urine by gas chromatograph mass spectrometry (GC-MS). C3 level of acylcarnitine analysis elevated 10.4 uM/L (range, 0.200-5.00) in plasma. We took gene analysis for PA to be based on the symptoms and laboratory results. We detected PCCB gene mutation and diagnosed PA. She survived without severe neurologic defects and complications and was hospitalized only three times with upper respiratory tract infections for 7 years. We report a case of a ten days old neonate with PA presenting without severe metabolic acidosis and hyperammonemia who was effectively treated with early aggressive care and conventional methods.

Cooking oil and yolk mixture (COY), a environmentally acceptable plant protection agent, and COY+$CaCO_3$+neem oil mixture were studied to control the powdery mildew occurring on eggplant, paprika, cherry tomato and maturity tomato in glass houses and vinyl houses during 2005 to 2007. The morphological changes of the pathogenic fungi on the leaf surface before and after treatment of COY were observed. COY made of rape seed oil and COY+$CaCO_3$+neem oil mixture were sprayed three times with 5 days interval to foliar parts of eggplant, paprika and tomato and the disease development were examined 5 days after final spray. In eggplant, the control efficacy of COY to powdery mildew was 94.6%. In paprika, the control efficacy of COY to powdery mildew was 91.6% and that of COY+$CaCO_3$+neem oil mixture was 96.2% that revealed little higher than COY itself. In tomatoes(cherry or maturity tomato), the control efficacy of COY were about 91 %, however, when COY mixture were sprayed to tomato leaves and stems the powdery mildew was controlled completely. Typical and healthy mycelia, conidiophores and condia were observed through scanning electron microscope in COY unsprayed leaf surface, on the other hand destroyed and winkled mycelia and conidiophores were observed in COY treated leaves regardless host plants nor taxonomic differences of fungi.

The present study was designed to estimate the seroprevalence of NLVs among diarrheagenic children and in healthy adults in Seoul and its vicinity with the use of an EIA and an Western blot (WB) based on recombinant Norwalk virus capsid protein (rNV) and crude virus preparations as antigen. Seroconversion was observed in 34 (83%) of 41 tested using the EIA and in 21 (54%) of 39 using the WB, suggesting that the NLVs with epitopes common to rNV are prevalent in Seoul area. Diarrheal children who were known to have been infected with several other strains of the NLVs showed no significant antibody response to the rNV. Infection with rNV occurred earlier in life: primary infections with rNV were common before the age of 6 months and over 91 % of children had evidence of infection by that age by the EIA. Since the amount of the NLV antigens available for seroepidemiologic surveys is limited, we tried to detect NLV antibody by using crude virus preparations as antigen. One crude virus preparation of a child whose stool yielded genetically distinct NLV revealed the presence of the plural number of bands upon SDS-PAGE, but precipitated only one band (62 kDa) after the WB with a serum (collected 10 days after the onset of symptoms) of another diarrheal child. The WB assay we present in this report revealed that the NLVs are prevalent among Korean population and that the sera contained antibody to a single major structural protein, with molecular sizes of 58 to 62 kDa, compatible with the sizes reported for the Norwalk virus and Snow Mountain agent proteins, respectively. When the results of the WB were compared with those obtained by the EIA, the EIA antibody assay was sensitive enough to detect an antibody rise of as much as 4096-fold but not as specific as the WB. The WB assay presented in this paper will provide a powerful tool to elucidate not only antigenic structures of the NL Vs but also seroepidemiology of the NLV infection. The availability of an unlimited source of antigen will enable a large scale serologic studies that will greatly increase our understanding of the role of NLVs in human enteric illness.

Purpose : Asymptomatic infections with positive throat culture for group A beta-hemolytic streptococci(GABHS) and high antistreptolysin O(ASO) concentration may lead to sequelae such as rheumatic fever or acute poststreptococcal glomerulonephritis. Children with asymptomatic infections were treated with oral penicillin V to evaluate the effectiveness of penicillin treatment on the asymptomatic infections. Methods : Throat culture and ASO concentration analysis were performed against healthy elementary school children. Thirty-six children with positive throat culture for GABHS and ASO concentrations of 400 IU/mL or more were divided into two groups. Twenty-two children were treated with oral penicillin V for 10 days, and the others were not treated. Eradication rate of GABHS and the change of ASO concentration between the two groups were compared after one month later. Results : Eradication rates of GABHS between treated and untreated children were 91%(20/22) and 50%(7/14) respectively(P<0.05). Children showing elevation of ASO levels more than 100IU/mL were 22%(4/18) in the treated group and 30%(3/10) in the untreated group, while children showing a decrease of more than 200IU/mL in the ASO level were 44%(8/18) and 40%(4/10) respectively. Conclusion : We confirmed the validity of penicillin treatment, because when we treated the asymptomatic children with penicillin V, the GABHS was eradicated effectively. But there was no significant difference of decrease in the ASO levels between the two groups due to long half-life of ASO or poor compliance. Treatment failure was 22% in terms of elevated ASO levels after penicillin treatment.
