Objectives: The purpose of this study was to evaluate self-reported symptoms of periodontal diseases. We performed a comprehensive analysis of periodontal health related factors. Methods: 581 volunteers representing a broad range of age from 20 to 65 were recruited from Seoul and Gyeonggi provinces. They participated in a self-administered survey of which the results were analyzed through the decision tree analysis using the data mining program. Results: 67% of the participants reported 'bad breath,' whereas 13.9% of participants reported 'toothache'. The decision analysis revealed that age was the most determining factor of adult periodontal health. Participants in 20s with a profound understanding of their periodontal health status exhibited a low vulnerability to periodontal diseases, whereas those lacking the awareness were more susceptible to the diseases. However, other participants in 30s and older showed a higher vulnerability to periodontal illness than those in 20s, whether or not they had suffered from chronic diseases. Conclusions: In order to effectively prevent periodontal diseases, an age-appropriate clinical approach will be necessary. For the younger age group it will be crucial to enhance the self-awareness of their current oral health status. On the other hand, those in 30s and older will need to pay a close attention to the prevention of chronic periodontal disease.

The aim of this study was to analyze a group of pre-service elementary teachers experience on the cognitive terms of biology inquiry subjects, and experience on living materials related with the domain of life in the Korea elementary school science textbook. Firstly, elementary school pre-service teachers had the confidence of inquiry subjects related with the domain of life such as 'when we take breath what will happen in human body?' and 'Can we make the model of human body?' But they did have the most diffidence of 'The search for pieris rapae, a cabbage butterfly's life', 'Can we grow the little creature?' The reason why pre-service elementary teachers had diffidence of comprehending experiment procedure and planning ability was that 'they focused on understanding the scientific concepts instead of planning experiments by themselves', and 'they carried out the least amount of experiments' Secondly, elementary school pre-service teachers had never experienced biology materials related with the domain of life in the Korea elementary school biology science textbook such as 'tradescantia reflexa', 'Caddis larva', 'hydrilla verticillata', and 'Plantain lily.' According to the findings obtained from the study, the reason why they had never seen the biology materials was that they had the least opportunity of immediately observing life creatures due to memorization-intensive classes.

The purpose of this empirical study is to test hypotheses in order to identify the cost drivers that drive indirect costs in general hospitals in Korea. In various cases' studies, it has been suggested that overhead costs are driven by volume and complexity variables, how they are structurally related and how the cost impacts of these variables can be A unique feature of the research is the treatment of complexity as an endogenous variable. It is hypothesized that level of hospital complexity in terms of the number of services provided(i.e., “breath" complexity) and the intensity of individual estimated in practice. overhead services(ie., “depth" complexity) are simultaneous determined with the level of costs needed to support the complexity. Data used in this study were obtained from the Database of Korean Health Industry Development Institute, Health Insurance Review Agency and analyzed using simultaneous equation model, path model. The results found those volume and complexity variables are all statistically signi-ficance drivers of general hospital overhead costs. This study has documented that the level of service complexity is a significant determinant of hospital overhead costs, caution should be exercised in interpreting this as supportive of the cost accounting procedures associated with ABC. with ABC.

Purpose: In this study, relationships between symptom experience and quality of life in a cross-sectional sample of patients with Atrial Fibrillation (AF) were investigated. Methods: This descriptive study involved a convenience sample of AF patients from S university hospital, C city. One hundred and two AF patients completed psychometric validated measures of AF related symptoms and quality of life. Descriptive statistics and Pearson correlation coefficients with SPSS WIN 14.0 were used for data analysis. Results: Of 16 atrial arrhythmia-related symptoms, the patients reported 'tiredness' as the most frequent and 'shortness of breath' as the most severe. The level of overall quality of life for patients with AF was 53.92. There were significant differences in symptom frequency according to religion, New York Heart Association (NYHA) classification and left ventricular ejection fraction ; symptom severity according to monthly income and stroke ; quality of life according to age, job, alcohol intake, NYHA class and stroke. Quality of life for these patients was positively correlated with symptom frequency and symptom severity. Conclusions: This study demonstrated that patients with more frequent and severe symptoms perceive poorer quality of life than patients with less frequent and less severe symptoms. Symptom experience should be assessed early to improve quality of life for patients.

The purpose of this study is to research high school students' stressful life events, to examine effects of SES, psychological environments, stress coping methods on stress. Data were collected by 965 high school students in Cheon-buk. Data were analyzed with the frequency, percentage, factor analysis, reliability, ANOVA test, Multiple Regression in use of SPSS WIN 7.5 Program. The main results are as follow: 1. High school students; stressful life events are ① comparingㆍinterferenceㆍscolding ② having a bad at their study. ③ educational environments ④ ability ⑤ apearance. Peoples stressed me are ① her(him)self ② friend and ③ teacher. Stress coping behaviors are it's ① speak ill a person. ② listen to the music. ③ sleep. ④ be patient. ⑤ keep still or take breath deeply. 2. SES, Psychological Environments, Stress Coping Methods are related to stress. Especially hopeless in future, parental not affections and parental interference are related to stress highly. Also the stress by sex discrimination are related to gender intimately. 3. Effects of SES, Psychological Environments, Stress Coping Method on high school students' stress are very different. So it must to be differentiated the support on the high school students' stress.

Interest and demand for hydrogen sensors are increasing in the field of H₂ leakage detection during storage/transport/use and detection of H₂ dissolved in transformer oil for safety issues as well as in the field of breath analysis for non-invasively diagnosing a number of disease states for a healthy life. In this study, various ZnO-based sensors were synthesized by controlling the reduction in crystallite size, decoration of Pt nanoparticles, doping of electron donating atoms, and doping of various atoms with different ionic radii. The sensing response of the various prepared ZnO-based nanoparticles and quantum dots (QDs) for 10 ppm H₂ was investigated. Among the samples, the smallest-sized (3.5 nm) In³⁺-doped ZnO QDs showed the best sensing response, which is superior to those in previously reported hydrogen sensors based on semiconducting metal oxides. The higher sensing response of In-doped ZnO QDs is attributed to the synergic effects of the increased number of oxygen vacancies, higher optical band gap, and larger specific surface area.

Objective : The region, observation period, figuration of pulse, pulse frequency, process of diagnosis and related diagnostic methods in traditional pediatric pulse diagnosis were studied in this article. Method : The articles related to traditional pediatric pulse diagnosis in Traditional medical classics, and analysis to the characteristics of it was done, then lastly, the principle of pulse manifestation and the meaning of application to modern times were considered. Result & Conclusion : It is difficult to catch the figuration of pediatric pulse because of dynamic change of body conditions, fast heartbeat and narrow region of pulse. Therefore, the pulse diagnosis appropriated for children have been developed and combined with the special diagnosis methods, for example, palpation of forehead and observation of index finger. The traditional pediatric pulse diagnosis is done with just one finger palpation in the period of 3 to 5 years old to identify the speed, length, size and height of pulse. The standard average of pulse frequency is 7~8 par breath in the period of 3 to 5 years old according to traditional medical classic.

Trimethylaminuria (TMAuria), known as "fish odor syndrome," is a congenital metabolic disorder characterized by an odor resembling that of rotting fish. This odor is caused by the secretion of trimethylamine (TMA) in the breath, sweat, and body secretions and the excretion of TMA along with urine. TMAuria is an autosomal recessive disorder caused by mutations in flavin-containing monooxygenase 3 (FMO3). Most TMAuria cases are caused by missense mutations, but nonsense mutations have also been reported in these cases. Here, we describe the identification of a novel FMO3 gene mutation in a patient with TMAuria and her family. A 3-year-old girl presented with a strong corporal odor after ingesting fish. Genomic DNA sequence analysis revealed that she had compound heterozygous FMO3 mutations; One mutation was the missense mutation p.Val158Ile in exon 3, and the other was a novel nonsense mutation, p.Ser364X, in exon 7 of the FMO3 gene. Familial genetic analyses showed that the p.Val158Ile mutation was derived from the same allele in the father, and the p.Ser364X mutation was derived from the mother. This is the first description of the p.Ser364X mutation, and the first report of a Korean patient with TMAuria caused by novel compound heterozygous mutations.

Objectives : In general, the active of volatile compounds which become usually known as the principal ingredient of bad breath is closely connected with temperature. In this study, an investigation was made into the correlation between oral malodor and the temperature of rinsing water. Specifically, an analysis was made of saliva in rinsing water with relation to amount, flow and pH. In addition, a calculation was made of O'Leary index. The results are expected to be basic data for oral malodor reduction plans. Methods : A total of 30 women who are in their 20s without any systemic disease and teeth braces and non-pregnant were chosen for the study. The research was carried during 3 weeks from 28 Mar to 11 Apr in 2011. Results : Saliva was not significantly affected by the temperature of rinsing water, in connection with saliva amount, saliva flow and saliva pH. The O'Leary index and oral malodor was the highest in warm water, but the subjects preferred rinsing with cold water. Conclusions : In conclusion, oral malodor was found to be reduced in inverse proportion to the temperature of rinsing water. Thus, it is recommended to rinsing water with warm water after tooth brushing.
