  • There is a growing interest in halitosis and diverse Korean medical studies are being conducted about it. But there are few study about teatment effect of halitosis after Korean medical care, treatment duration, and factor affecting recovery rate. Thus, the purpose of this study is to research clinical characteristic of halitosis patients, factor affecting halitosis, recovery rate of halitosis, treatment duration, factor affecting recovery rate by analyzing halitosis patients retrospectively. People who were over 19 and visited Korean medical clinic in Seoul to want to be treated halitosis in 2014 were analyzed retrospectively. We analyzed general and living characteristics of halitosis patients, halitosis-related symptoms and diseases, level of halitosis and halitosis-related symptoms both before and after treatment, treatment duration of halitosis patients, prescription of halitosis patients, recovery rate of level of halitosis and halitosis-related symptoms by general characteristic and duration of symptoms. Female, thirties, and Nonsmoker had the highest proportion in general characteristic. The average duration of halitosis is 41.6months and treatment duration is 2.55months. The average of sensory evaluation score is 3.40±2.53, subjective evaluation score is 5.02±1.53, lump sensation on throat is 3.52±2.50, postnasal drip is 1.11±1.88, dry mouth is 4.13±2.17, quality of life is 6.07±1.13. Gamichiuitang is used the most among prescriptions. Sensory evaluation, subjective evaluation, lump sensation on throat, postnasal drip, dry mouth, and quality of life had better score compared with pre-treatment. Duration of symptoms is in weak inverse proportion to sensory evaluation, subjective evaluation, dry mouth, quality of life. This study is meaningful in the way to find recovery rate of halitosis after korean medical care, treatment duration, and factor affecting recovery rate not progressed until now. But this study also has limits such as not analyzing objective data using halitosis measuring instrument and lack of methodical scale about quality of life. Therefore, succeeding study such as clinical trials is needed to verify reliability of Korean medical treatment.

  • Physicochemical properties and suitability of domestic wheat varieties for production of sugar-snap cookie were examined. Four kinds of commercially available wheat flour and six kinds of other domestic wheat varieties were tested. Domestic wheat varieties had protein contents ranging 7.7 to 11.5%, alkaline water retention capacity (AWRC) of 54.6 to 65.2%, Pelshenke values of 17 to 31 min, and sedimentation values of 19.6 to 30.8 mL. Peak viscosity range of Korean wheat flours measured by Rapid Visco Analyser was from 134.4 to 346.3 unit. Diameter of cookies fer US soft wheat flour was 7.8 cm and domestic wheat flours ranged from 7.2 to 7.9 cm. Cookie spread factors for Alchanmil, Tapdongmil, and Woorimil flours were higher than those of other flours. Protein content had significantly high correlation coefficient of $r=0.892^{**}$ with sedimentation value, and showed negative correlation with cookie diameter, spread factor, and top grain score. AWRC values had significantly high correlation coefficient of $r=-0.736^{**}$ with cookie diameter. Spread factor of cookie showed positive correlation with top grain score.

  • Objectives : This study developed and validated the Perceived Stigma of Delirium Scale(PSDS), which is designed to measure perceived stigma associated with delirium in patients suffering from that disorder. Methods : Based on a literature review of scales assessing stigma, a preliminary scale comprising seven items was developed. After recovering from delirium, 128 patients completed the PSDS and the Distress Thermometer (DT). Factor analysis was used to examine construct validity, and internal consistency and test-retest reliability were examined to ensure reliability. Concurrent validity was assessed using the correlation between the total scores on the PSDS and the DT. Results : Factor analysis yielded a single-factor structure from the seven candidate items. One item was excluded due to low factor loading. The internal consistency was computed and Cronbach's ${\alpha}$ was 0.85 for the total score. The overall test-retest reliability was 0.71, with items ranging from 0.58 to 0.83. The total score on the PSDS was significantly correlated with the DT score. Conclusions : The PSDS may be a reliable, valid instrument for evaluating perceived stigma in patients who have recovered from delirium. Further study of the perceived stigma by delirium patients is required to assess the implications of the PSDS for clinical practice and research.

  • Objectives : This study was conducted to investigate the prevalence of victims of bullying and the demographic characteristics of victims, and their related psychopathology, in a Korean nationwide sample of youths in middle and high school over a one month period. Methods : During the autumn of 2009, students in the 7th to 12th grades at 23 secondary schools participated in a nationwide, cross-sectional study. The study subjects completed the Adolescent Mental Health and Problem Behavior Screening Questionnaire-II (AMPQ-II) and Symptom Checklist-90-Revision (SCL-90-R). Based on the data acquired, descriptive statistics, correlation coefficients and multiple logistic regression analysis were performed. Results : Among the 3364 participants, 2272 (67.54%) completed the questionnaire. The prevalence of victimization was 28.9%. Male gender was positively associated with victimization, and grade level was negatively related to victimization. The AMPQ-II bullying score (Factor 4) was significantly (p<.001) and positively correlated to the AMPQ-II student total score (r= 0.50), Worry and thought (Factor 1 ; r=0.38), Mood and suicide (Factor 2 ; r=0.31), Academic and Internet-related problems (Factor 3 ; r=0.24), Rule violations (Factor 5 ; r=0.23), and AMPQ-II teacher total score (r=0.11). Somatization (r=0.23), Obsessive-compulsive behavior (r=0.24), Interpersonal sensitivity (r=0.30), Depression (r=0.33), Anxiety (r=0.26), Hostility (r=0.30), Phobic anxiety (r=0.22), Paranoid ideation (r=0.36), and Psychoticism (r=0.31) results from the SCL-90-R were also found to be positively related to the AMPQ-II bullying score, and remained significant after adjusting for age and gender. A total of 26% of the victims reported suicidal ideations as compared to 9% of non-victims over the month prior to the evaluation ($x^2$=119.595, df=1, p<.001). The multiple logistic regression analysis indicated that the AMPQ-II bullying score significantly increased the risk of suicidal ideation [Exp(b)=1.55, df=1, p<.001] after adjusting for age and gender. Conclusion : School bullying was highly prevalent among Korean middle and high school students. This study provided strong evidence that suicidal ideation and psychopathology were serious problems among the victims of bullying.

  • The purpose of this study is to investigate the effect of social capital on Goendang(relatives) culture, which is a traditional local community culture, and local development as a positive factor. In order to evaluate the effect of social capital, a survey targeting 600 Jeju residents was conducted and 594 returned questionnaires were interpreted for the final analysis. Descriptive analysis, T-test, ANOVA analysis, and multiple regression analysis were conducted on the collected data, using SPSS 18.0. As a result, firstly, the levels of social capital of the surveyed appear as follows: network (average score 4.01), trust (average score 3.80), norms (average score 3.43), cooperation (average score 3.00), and participation (average score 2.80). Secondly, there are differences in social capital among the surveyed groups based on urban-rural areas, administrative districts, and average monthly income. Finally, among the dimensions of social capital, as the relative importance of network and participation increases, the surveyed think that they need Goendang culture more. Also, i t turns out that as the relative importance of norms and participation increases, Goendang culture can exert influence on local development as an important influence factor. Therefore, based on the analysis, this study shows that nurturing social capital can allow people to utilize Goendang culture for local development as a positive community culture.

  • The purpose of our study was to retrospectively evaluate the cause of a decreased calcium score of follow-up studies on coronary artery calcium scores (CACs) computed tomography (CT). The subjects were healthy 100 people(85 males $60.6{\pm}6.9$ years, 15 females $67.2{\pm}7.3$ years). The subjects decreased CACs were divided into 4 subgroups depending on Agatston classification, minimal (1-10), mild (11-100), moderate (101-400), severe (400<). As a result of decreased CACs were scan location disagreement 51%, motion artifact 26%, equipment changes 14%, operator mistakes 5%, input miss 2%, image loss 1%, arrhythmia 1%. In the mild group, the most common decreased CACs were 49 people. In the minimal group, the most significant variation reduction has occurred to 6 people. Scan location disagreement was considered a partial volume effects due to the scan starting position. It showed less than 100 CACs a high variation (19.7%) in more than 100 CACs, a lower variation (2.2%), these could be seen that the variation range is different that can be tolerated according to the calcification score. Motion artifact factor was found in 26%, which is so closely related to the preceding tests that affect the higher heart rate like this pulmonary function test, exercise stress test.

  • Objectives The purpose of this study was to revise Sasang Digestive Function Inventory (SDFI) and improve its validity and reliability using clinical data. Methods The Sasang type and Cold-Heat pattern differentiation by certified clinical specialist and responses to SDFI items were acquired from 419 hospital patients. The revision of SDFI was performed using item analysis and Explorative Factor Analysis (EFA). Furthermore, the validity and reliability of the revised SDFI (rSDFI) were investigated using Confirmatory Factor Analysis (CFA), Internal Consistency and Item Response Theory (IRT). And, clinical significance of the rSDFI was examined for the differentiation of Sasang types and Cold-Heat patterns. Results The number of the SDFI items were modified from 21 to 15. And, the validity and reliability of the rSDFI subscale structure were found to be acceptable. The scores of rSDFI-total and rSDFI-E significantly decreased in the order of Tae-Eum (TE), So-Yang (SY), So-Eum (SE) types, and the rSDFI score of SE type was significantly lower than that of TE and SY types. The rSDFI-total score could differentiate Cold-Heat pattern in both SY and SE types. And the difference of digestive function between Cold and Heat pattern of SE type could be explained with the rSDFI-D score. The rSDFI-total score in Cold pattern significantly decreased in the order of TE, SY, and SE types, and the rSDFI-total score of TE type is significantly higher than that of SE type in Heat pattern. Conclusions Current results demonstrated the reliability, validity and clinical usefulness of the rSDFI in clinical patients. Therefore, rSDFI can be utilized as an objective clinical measure supporting the differential diagnosis of Sasang typology.
