This is a short-term longitudinal study investigating the relationships between changes in mental health and academic burnout among Korean middle school students. Study sample consisted of 409 middle school students in Seoul provision, with 161 male, 216 female, and 32 unidentified. Both Symptom Check List(SCL-47) and Maslach Burnout Inventory-Student Survey(MBI-SS) were used. In order to examine the pattern of changes in mental health and academic burnout among students, standardized residuals were calculated using regression equations which were then put into canonical correlation analysis. The results of this study are as follows. First, according to Function 1, among sub-factors of mental health, decreases in depression, compulsion, anxiety, and hostility were particularly associated with decreases in exhaustion and cynicism among academic burnout. Put in another way, students who showed increases in depression, compulsion, anxiety, and hostility experienced more academic exhaustion and cynicism. Second, according to Function 2, increases in phobic anxiety, compulsion with decreases in anxiety, depression were associated with decrease in academic exhaustion and increase in cynicism. Considering Russell's dimensional theory of emotion, Function 1 showed that mental health symptoms including both aroused and non-aroused affects were related with increases in exhaustion and cynicism while Function 2 showed that mental health symptoms including only aroused aspects were related with decrease in exhaustion and increase in cynicism. Thus, a conclusive intervention program seems to be required to deal with both aroused and non-aroused affects of students who are experiencing increased exhaustion and cynicism. On the other hand, an intervention program focused on aroused affects seems appropriate to students who are experiencing decreased exhaustion and increased cynicism. This study has its value in that it has enhanced understanding of students in school and counseling settings by revealing the relationships between mental health and academic burnout among adolescents and suggested differentiated intervention strategies based on patterns of students' academic burnout.

Purpose : To evaluate the usefulness of cervicothoracic spine sagittal T2-weighted images (CT SAG T2WIs) included in routine lumbar spine MRI. Materials and Methods: Institutional review board approval was obtained and informed consents were waived for this retrospective study. The study group comprised 2,113 patients who underwent lumbar spine MRI from January 2005 to December 2005. CT SAG T2WIs were added in the routine lumbar spine MRIs. Radiologic reports were reviewed retrospectively for pathologic lesions on CT SAG T2WIs by one radiologist. Information of additional cervical or thoracic spine MRI and/or CT for further evaluation of positive findings on CT SAG T2WIs and their treatment were collected by retrospectively reviewing medical records. Results: The CT SAG T2WIs revealed 142 pathologic lesions in 139 (6.58%) of the 2,113 patients. They were easily obtained without positional change in a scan time of less than 2 minutes. Additional cervical or thoracic spine MRI and/or CT for positive findings on CT SAG T2WIs were performed in 13 patients. Seven patients underwent surgical treatment. Conclusion: CT SAG T2WIs included in routine lumbar spine MRI were useful in finding the pathologic lesions in cervicothoracic spine for the patients who assumed to have lesions in lumbar spine.

The effects of dietary fiber isolated from Synurus deltoides on constipation induced by loperamide (4 mg/kg/day) were investigated. Food intake and body weight both decreased in the 5% S. deltoides dietary fiber and loperamide-treated group (SD5) and 10% S. deltoides dietary fiber and loperamide-treated group (SD10), whereas fecal water contents increased by 2.4 and 3.4-fold in the SD5 and SD10 groups, respectively. The concentrations of total-cholesterol, HDL-cholesterol and triglyceride in the sera of the SD5 and SD10 groups were lower than those in the control (C) group. However, the biochemical parameters, GOT (glutamic oxaloacetic transaminase), GPT (glutamic pyruvic transaminase), and glucose levels, were not affected by the level of S. deltoides. In addition, the concentrations of total-cholesterol and triglyceride in the livers of the SD5 and SD10 groups were also significantly lower than those in the control group. These results suggest that dietary fiber isolated from S. deltoides might ameliorate constipation symptoms, and lower lipid concentrations in the blood and liver.

High Internet usage and the public's keen interest on health have influenced the health care system, and a potential value of the online health information and medical consultation market is immense. This study reveals results from data collected from Seoul residents in the age group of 20s in 2011. Out of 499 respondents, 75.2% answered that they used online health information; however, only 7.2% answered that they have used online medical consultation services. Findings on the purposes of using online medical consultation included treatments of symptoms(33.6%) and self-disciplines of one's health(19.5%). Mostly used Websites for health information search included search engines and blogs, but respondents preferred to use government sites and hospital sites in the future. When choosing a medical consultation, respondents preferred a certain website for different reasons including creditability of the consultant(23.7%), creditability of the organization(23.7%), rapid responses(21.2%), and more. Overall, although health information search via web is being highly utilized among people in their 20s, utilization of online medical consulting is not. Thus, promotion efforts to increase awareness and utilization of online medical consulting based on the site selection criteria, type of personal information disclosure, and other preferences are essential. Also, creating websites meeting these criteria is important.

This study aimed to evaluate seaweed polysaccharide extracts as a cosmetic material. To assess anti-microbial efficacy, Staphylococcus aureus (S. aureus) was treated with seaweed polysaccharide extracts and zones of inhibition were measured. In addition, the anti-inflammatory effect was confirmed in RAW 264.7cells, and seaweed polysaccharide extracts was applied to the dorsal skin of Sprague-Dawley (SD) rats to evaluate single-dose toxicity. As a results, seaweed polysaccharide extracts did not exhibit cytotoxicity at concentrations up to $1,000{\mu}g/mL$ in skin fibroblasts. Furthermore, when S. aureus was treated with 1% seaweed polysaccharide extracts, clear zones of $1.52{\pm}0.34cm$ formed, confirming sufficient anti-microbial activity. When RAW 264.7 cells were treated with seaweed polysaccharide extracts extract, nitric oxide (NO) production decreased in a concentration-dependent manner and the production of inflammation-related cytokines, such as interleukin 1 beta ($IL1{\beta}$), tumor necrosis factor alpha ($TNF{\alpha}$), and prostaglandin E2(PGE2), decreased. When seaweed polysaccharide extracts extract was applied at various concentrations to rats, symptoms did not change for more than 14 d, and there was no change in body or organ weights. In conclusion we found that seaweed polysaccharide extracts is not cytotoxic and has anti-microbial and anti-inflammatory effects. Therefore, it is suitable for use as a cosmetic material.

Moyamoya disease is a disorder in which certain arteries in the brain are constricted. Blood flow can be blocked by the constriction and blood clots. The patients frequently experience transient ischemic attacks (TIA), cerebral hemorrhage, or may not experience any symptoms at all. It is reported that they have a higher risk of recurrent stroke and a distinct underlying pathophysiology. A 3-year-8-month old boy with moyamoya disease experienced cerebral infarctions five times, and he underwent a cerebrovascular anastomosis surgery four years ago. He showed swallow disturbance, general delayed development, hemiplegia, and strabismus. Also he had hypocalcified teeth with or without multiple caries lesions in all dentitions. Dental treatment under general anesthesia using sevoflurane was performed due to his lack of cooperation. Moyamoya disease is associated with various medical conditions requiring a thoughtful deliberation and a careful examination before and during dental treatment. Pain and anxiety control during dental treatment is important because hyperventilation induced by crying has been seen to trigger TIA. Both isoflurane and sevoflurane are commonly used in patients with MMD, but dynamic autoregulation is better preserved during sevoflurane than isoflurane anesthesia. So sevoflurance general anesthesia may be recommendable to manage dental patients having multiple caries with moyamoya disease.

In this study, investigated the general characteristics and diagnostic methods types of streptococcosis among various fish disease pathogens that caused a lot of economic damaged to aquaculture fish based on the previous research paper. Streptococcosis infection of fish is considered a reemerging disease affecting a variety of wild and cultured fish throughout the world. Calssifiacation of Gram positive cocci based on DNA-DNA hybridization coupled with 16S sequencing has shown that at least five different species are considered of significance as fish pathogens: Lactococcus garvieae, L. piscium, Streptococcus iniae, S. agalactiae, S. paruberis, Vagococcus salmoninarum. Symptoms of infection with streptococcosis disease such as body color change, eyeball abnormality, gill discoloration, bleeding, abdominal distension, swelling of the kidney and spleen. In addition, it usually occurs from June to October when the water temperature rise a lot of fish death. Currently, 16S rRNA, 16S-23S rRNA intergenic spacer region (ISR), Random Amplified polymorphic DNA (RAPD), Ribotyion (RT), Loop-mediated isothermal amplification (LAMP) are among the methods for diagnosing streptococcosis. Among them, the LAMP method, which is high applicable to the aquaculture farm has attracted the spotlight, but due to problems such as confirmation of results. This seems to minimize the economic loss of streptococcosis which complements the problem so that it can be easily used from the diagnosis to the results confirmation.

This paper was trying to investigate the periodontal health recognition and self oral hygiene behaviors and figure out that relationship. The results having analyzed 592 questionnaires returned patient who had visited the dental clinic which is selected randomly were following. There were relationships between the periodontal health recognition and self oral hygiene behaviors. Self oral hygiene behaviors were significantly high when, women did than men did, education level, subjective oral health status, and periodontal health recognition about managements were higher and periodontal health recognitions about treatment were lower. It was the periodontal health recognition that was influential the most in the independent variables. Therefore, knowledge related to the periodontal health should be educated to the patients visiting the dental clinic, and the patients should receive helps to perform self oral hygiene behaviors by inducing the transition of attitude to periodontal health.

The purpose of this study was to evaluate the association between oral health status and oral health-related quality of life (OHRQoL) by using the Oral Health Impact Profile-14 (OHIP-14) among adolescents in a metropolis of Korea. A total of 119 students in 1st grade in middle school and 1st grade in high school participated in this cross-sectional study. Oral examination was conducted by two trained dentists to collect in for mation about Decayed, Missing, and Filled Teeth (DMFT) and Community Periodontal Index (CPI). OHRQoL was evaluated by short-form of OHIP-14. Wilcoxon correlation, Kruskal-Wallis test and multiple regression analyses were performed to assess the association between oral health status and OHRQoL. All data was analyzed by SPSS 22.0 and the significance level was set at 0.05. The average of OHIP-14 score in adolescents having no dental caries ($17.88{\pm}5.13$) was higher than those having more than one DMFT index ($19.75{\pm}7.16$). The average of OHIP-14 score in adolescents having bleeding observed ($20.21{\pm}8.01$) was higher than those having more than calculus detected ($18.66{\pm}5.65$). The level of OHRQoL was higher in the participants perceiving better oral health condition compared to those perceiving poorer condition (p<0.05). The result of this study could provide the information that OHRQoL from adolescents positively associated with self-assessed oral health status than oral health with DMFT and CPI. Further studies are needed to well-designed follow-up studies.
