Recent cross-sectional studies indicate that obesity is a risk factor for periodontal disease. This study was aimed to investigate whether the four-week weight control program including caloric restriction and exercise training could have an effect on periodontal health. Forty-one obese (body mass index [BMI] ${\geq}25.0$) and five overweight ($23.0{\leq}BMI<25.0$) students participated in the weight control program. Anthropometric data and oral examination data were collected at the baseline and at the 27th day. BMI, waist hip ratio (WHR), and percent of body fat (PBF) of the subjects decreased significantly, but gingival index, sites with bleeding on probing (BOP), and sites with shallow pocket depth didn't show the significant changes in paired t-test. There was no difference in the outcomes according to smoking, drinking alcohol, and sex. Nevertheless, PBF and sites with BOP (r=0.777) and WHR and sites with shallow pocket depth (r=0.444) showed positive correlations. PBF accounted for 58.9% of the variance in sites of BOP in regression analysis. We suggested that obesity might relate with periodontal health, although it was not clear whether weight control could influence on periodontal health directly.
This study aimed to investigate the relationship between sleep duration and periodontitis in adult Korean women. This cross-sectional study was based on the 2014 Korea National Health and Nutrition Examination Survey (KNHNES). We selected the data from 3,292 women (over 19 years of age) out of 7,550 participants for analysis, after excluding data from men. Complex logistic regression analysis was performed to determine the effect of sleep duration on the risk of periodontitis; the crude and adjusted odds ratios (ORs) were calculated. The risk of periodontitis was higher in participants who had a sleep duration of 7 hours or more, than in those with less than 7 hours (crude OR) by 1.37 times (95% confidence interval [CI], 1.13~1.65). The adjusted OR of the participants after adjusting for the sample characteristics of the participants (age, education level, income level, diabetes, hypertension, obesity) was 1.04 times (95% CI, 0.82~1.32), but the risk for periodontitis was slightly higher, though not statistically significant. This study confirmed the relationship between sleep duration and the risk of periodontitis in Korean women. Therefore, it is necessary to develop and implement a comprehensive health promotion program that can improve the proper sleeping habits of adult women in Korea and to combine oral hygiene management programs to prevent periodontal disease.

Serodiagnosis of Clonorchis sinensis infections will probably be a first choice tool for screening of clonorchiasis in a future because of increasing difficulties in collection and examination of stools. The sensitive test such as ELISA can he used effectively. However there are some limitations in serological diagnosis for the detection of serum antibody. One of the major problems is the non-specificity of the antigens which produce cross reaction with other helminthic infection sera. To solve this problem. many investigators have tried to purify the antigens used. In this study, we determined the antigenic profile of the crude saline extract antigen of C. sinensis at early developmental stage based on SDS-PAGE and immunoblotting techniques for the purpose of understanding the nature of C. sinensis worm antigen The following results were obtained : 1) The SDS-PAGE showed many protein hands ranging from 10Kd to 91Kd relative molecular weight. Among them, 66, 46, 40, 33, 27, 24, 16, 14 and 10Kd bands were observed as a principle bands. The protein components of C. sinensis changed chronologically during their early developmental period. 44Kd band was stained unclearly in antigen of 2 weeks worm, but changed to concentrated state in antigen of 5 weeks worm. 35Kd band was found in antigen of 2 weeks worm, however this band was disappeared in antigen of 5 weeks worm. 22Kd band also lost its staining property gradually. 2) In spite of differences in antigenic profile, there was no differences in the data obtained by microplate ELISA using each antigen preparation. Absorbance value began to rise in between 2 to 3 weeks after infection. 3) By EITB. serum antibody recognized major protein bands with molecular weight of 91, 85, 63, 46, 40, 33, 24, 14 and 10Kd hand respectively. Among them 66, 33, 17 and 14Kd bands were observed as non-specific band because they reacted even in normal control sera. Generally, gradual increase of positive reactions were observed as the infection period of C. sinensis was prolonged. In other hand, the reaction of 10Kd hand did not occurred when 26th week sera was tested. 4) The positive reactions using antigens of 2 weeks worm, especially on 40 and 24Kd bands, were most strong and sharply demarcated compared to those of 3~5 weeks worm antigen.
Occlusal plane is a sagittal expression of dental arch form, and it composes the shape of occlusion, which is one of the most important elements of Maxillo-oral system. In this case, vertical, horizontal coordinates of bionic-median-sagittal plane was produced in articulator, and to achieve relation of left and right position of upper, lower teeth and deficits in alveola, Shilla system was used to reconstruct occlusal plane. In this case, a 41 year-old male patient visited for fracture of 10 unit metal-ceramic fixed partial denture of upper anterior teeth and for overall treatment. Clinical, radiographical, model examination was held, full mouth rehabilitation was achieved by placing dental implant. Maxillo-oral relation was recorded using Gothic arch Tracer complex and were mounted. And for the next step, we estimated original occlusal plane using Shilla system. After analysis we produced diagnosis wax pattern. On the basis of this, radiography stent was manufactured and dental implant was placed, and temporary prosthesis was made by using diagnosis wax pattern. Cross mounting and anterior guiding table were performed in order to reproduce temporary restoration morphology and bite pattern, followed by final restoration made of all ceramic crown with zirconia coping. As stated above, appropriately esthetic and functional results can be seen in using Shilla system in diagnosis and treatment procedure of full mouth rehabilitation patient.
Background: The aim of the study was to determine breast cancer risk and early diagnosis applications in women aged ${\geq}50$. Materials and Methods: This cross-sectional, descriptive field study focused on a population of 4,815 in Mansuro$\breve{g}$lu with a 55.1% participation rate in screening. In the study, body mass index (BMI) was also evaluated in the calculation of breast cancer risk by the Breast Cancer Risk Assessment Tool (BCRA) (also called the "Gail Risk Assessment Tool"). The interviewers had a three-hour training provided by the researchers, during which interactive training methods were used and applications were supported with role-plays. Results: The mean age of the women participating in the study was $60.1{\pm}8.80$. Of these women, 57.3% were in the 50-59 age group, 71.7% were married, 57.3% were primary school graduates and 61.7% were housewives. Breast-cancer development rate was 7.4% in the women participating in the study. When they were evaluated according to their relationship with those with breast cancer, it was determined that 73.0% of them had firstdegree relatives with breast cancer. According to the assessment based on the Gail method, the women's breast cancer development risk within the next 5 years was 17.6%, whereas their calculated lifetime risk was found to be as low as 0.2%. Statistically significant differences (P=0.000) were determined between performing BSE-CBE and socio-demographic factors. Conclusions: It was determined that 17.6% of the participants had breast cancer risk. There was no statistically significant difference between the women with and without breast cancer risk in terms of early diagnosis practices, which can be regarded as a remarkable finding. It was planned to provide training about the early diagnosis and treatment of breast cancer for people with high-risk scores, and to conduct population-based breast cancer screening programs.
Background: Cervical cancer is the second most common cancer in Thai women after breast cancer. Currently, the Papanicolaou (Pap) smear is the recommended procedure for cervical cancer screening in Thailand, but only a relatively small percentage of women follow this screening program. An alternative method to detect HPV genotypes associated with cervical cancer is self-sampling of urine, which is a more widely accepted method. Our study aimed to evaluate the prevalence of HPV in Thai women using urine and cervical swabs and prevalence of HPV in Thai men using urine samples. Materials and Methods: Tumorigenic HPV detection was accomplished by electrochemical DNA chip and PCR/direct sequencing. In addition to HPV prevalence, we report the concordance between different methods and sample types. One-hundred and sixteen women and 100 men were recruited. Histological examination revealed normal cytology in 52 women, atypical squamous cells of undetermined significance (ASCUS) in 9, low-grade squamous intraepithelial lesions (LSIL) in 24, and high-grade squamous intraepithelial lesions (HSIL) in 31. One-hundred men were classified as heterosexuals (n=45) and homosexuals (n=55). Results: The most prevalent HPV genotype in our study was HPV16. The HPV detection rate was generally lower in urine samples compared with cervical samples. Overall, there was good agreement for the detection of carcinogenic HPV from female cervical samples between the DNA chip and PCR/sequencing, with 88.8% total agreement and a kappa value of 0.76. In male urine samples, the level of agreement was higher in heterosexuals compared with homosexuals. Conclusions: Further improvement is required to increase an overall yield of HPV DNA detection in urine samples before clinical application of a urine-based HPV screening program. The electrochemical DNA chip test is a promising technique for carcinogenic HPV detection.

Objectives: The purpose of the study was to examine the expected role and competency of future public health dental hygienist. Methods: This study was cross-sectional design. One dental hygienist per 16 cities and provinces was selected from the list of Korea Society of public dental hygienists. After signing in the informed consent, the interview was carried out. Transcripts were made after each interview. Six researchers recorded meaningful contents in the transcripts. They classified and integrated the information that they had recorded commonly or not. Their opinions were converged by conference. Two supervisors verified results whether they were derived from actual recordings for the reliability of the results. The records were confirmed once again and corrected into common message. Results: The main difficult subjects in public health official examination were public health, English, and medical legislation to pass the examine. The preliminary certificates included public health related certificate, computer certificate, and driver's license. In the personality aspect, creativity, activeness, cooperation and good responsibility were very important trait to public health official. Among 16 interviews, 9 were positive and 5 were negative about the future prospects of a public dental hygienist. Conclusions: The future of public health dental hygienist will be positive. Throughout effort to prepare for the public health official, the public health dental hygienist will be expanded and in many ways the dental hygienists will take the charge of the important parts of the public health administration in the near future.
Objectives : We conducted this study to examine the association between serum GGT levels within the normal range and the risk factors of cardiovascular diseases Methods : We examined the cross-sectional association between serum GGT and the systolic and diastolic blood pressure, fasting blood glucose, total cholesterol, triglyceride, high density lipoprotein cholesterol (HDLcholesterol), and uric acid among 975 subjects that participated in the health examination of a university hospital located in Daegu city. All the patients' GGT levels were within the normal range. Results : After adjustment were made for age, body mass index (BMI), smoking status, drinking frequency, exercise frequency and coffee intake, the serum GGT level was positively associated with fasting blood glucose (p<0.01), total cholesterol (p<0.01), and triglyceride (p<0.01) in men, and it was positively associated with fasting blood glucose (p<0.01), total cholesterol (p<0.05), triglyceride (p<0.01), and uric acid (p<0.01) in women. The associations were not significantly different depending on the status of alcohol drinking or obesity, except for the associations of serum GGT with diastolic blood pressure (P for interaction=0.04) and uric acid (P for interaction=0.04) between the lean and obese subjects. Conclusions : Serum GGT levels within the normal range were positively associated with fasting blood glucose, triglyceride and uric acid in most subgroups irrespective of the drinking or obesity status. These results suggest that GGT has important clinical implications as being more than just a marker of alcohol consumption and hepatobiliary disease.
Objectives : To evaluate the effect of low-level exposure of air pollutants on the respiratory tract of the children living near the petrochemical estate in Ulsan. Methods : The study design was cross-sectional, and the study subjects consisted of 150 children(76 boys, 74 girls) living near the petrochemical estate and 100 children(53 boys, 47 girls) living in a suburban area. We investigated respiratory health using self-administered questionnaires(ATS-DLD-78) , radiological examination, and pulmonary function test such as FVC and FEV1. Results : There were higher prevalence rates of respiratory symptoms in the children living near the petrochemical estate than the children living in a suburban area. And the results of FVC and FEV1 of 11-years old children living near the petrochemical estate were lower than those of the children living in a suburban area. Conclusions : Chronic exposure of low-level air pollutants would affect respiratory health of the children. Therefore, further a longitudinal study of respiratory health will be needed for children living near the petrochemical estate in Ulsan.

Purpose : Skip the repetitive HRCT axial scan in order to reduce the exposure of patients during chest HRCT scan, Helical Scan Data into a reconstructed image, and exposure of the patient change and visually evaluate the usefulness of the HRCT images. Materials and method : Patients were enrolled in the survey are 50 people who underwent chest CT scans of patients who presented to the hospital from January 2015 to March 2015. 50 people surveyed 22 people men and 28 people women people showed an average distribution of 30 to 80 years age was 48 years. 50 patients to Somatom Sensation 64 ch (Siemens) model with 120 kVp tube voltage to a reference mAs tube current to mAs (Care dose, Siemens) as a whole, including the lungs and the chest CT scan was performed. Scan upon each patient CARE dose 4D (Automatic exposure control, Siemens Medical Solution Erlangen, Germany) was to maintain the proper radiation dose scan every cross-section through a device that automatically adjusts the tube current of. CT scan is the rotation time of the Tube slice collimation, slice width 0.6 mm, pitch factor was made under the terms of 1.4. CT scan obtained after the raw data (raw data) to the upper surface of the axial images and coronal images for each slice thickness 1 mm, 5 mm intervals in the high spatial frequency calculation method (hight spatial resolution algorithm, B60 sharp) was the use of the lung window center -500 HU, windows were reconstructed into images in the interval -1000 HU to see. Result : 1. Measure the total value of DLP 50 patients who proceed to chest CT group A (Helical Scan after scan performed with HRCT) and group B (Helical Scan after the HR image reconstruction to the original data) compared with the group divided, analysis As a result of the age, but show little difference for each age group it had a decreased average dose of about 9%. 2. A Radiation read the results of the two Radiologist and a doctor upper lobe and middle lobe of the lung takes effect the visual evaluation is not a big difference between the two images both, depending on the age of the patient, especially if the blood vessels of the lower lobe (A: 3.4, B: 4.6) and bronchi(A: 3.8, B4.7) image shake caused by breathing in anxiety (blurring lead) to the original data (raw data) showed that the reconstructed image is been more useful in diagnostic terms. Conclusion : Scan was confirmed a continuous, rapid motion video to get Helical scan is much lower lobe lung reduction in visual blurring, Helical scan data to not repeat the examination by obtaining HRCT images reorganization reduced the exposure of the patient.
