Objectives: The purpose of this research is to examine oral pathogen distribution among elderly with dementia in a care facility to understand the importance of preventively managing oral diseases in terms of preventively managing senile diseases. Methods: From 11th August 2015 to 11th October 2015, gingival crevicular fluid was collected from 130 subjects consisting of demented/non-demented elderly people aged above 65 in care facilities located in the regions of Busan/Gyeonggnam. Based on collected data, real-time PCR analysis on oral pathogen was conducted. Results: The demented elderly group consisting of female patients aged from 0 to 79 indicated higher ratios of T. denticola in comparison to the non-demented elderly group, and the demented elderly group consisting of female patients aged above 80 indicated a high ratio of S. mutans. It was confirmed that P. gingivalis and T. forsythensis categorized under the red complex are correlated, and that bacterial species categorized under the orange complex and bacterial species categorized under the red complex are correlated. Conclusions: Because eldery people with demntia are exposed to periodontal disease and dental caries, their oral environments are more vulnerable. In order to improve such environments, it is necessary to provide care facility personnel with an opportunity to receive education to become aware of the importance of oral health, and it is also necessary to compulsorily assign dental hygienists to care facilities so that they can serve as personnel specializing in oral health management.

본 논문에서는 공동주택 세대 내 바닥 충격음 저감을 위해서, 높은 밀도를 가지는 중량의 골재를 활용하여 단위중량을 높인 바닥 마감용 모르타르(이하, 중량모르타르)를 적용한 바닥구조가 연구되었다. 연구 결과에 따르면, 중량 모르타르를 적용한 바닥구조는 현장 바닥충격음 성능평가에서 중량충격음 2등급(뱅머신), 경량충격음 1등급의 성능이 측정되었다. In this paper, a floor structure applied with a mortar by using high-density aggregate (hereafter, a heavy mortar) was studied to reduce floor impact noise in an apartment house. As a result of study, the floor structure with the heavy mortar showed superior performance in the field floor impact sound performance evaluation.

This study analyzes the policy-making process of food safety regulations, focusing on the case of nutrition signpost labeling. The focus of the study is on the political and economic aspects of regulation. In particular, this study analyzes the benefit-cost structure and interests, the differences in political transaction costs, and bureaucratic incentives and behavior. The analysis finds that nutrition signpost labeling was a typical case which had dispersed benefits and a narrow-focused cost structure. The food industry has had an influential effect on government policy-making, while the public has not, as the food industry paid small information and organization costs by using aisles which had already been set. As a result, the food industry could reduce political transaction costs in the political market, and the low political transaction cost could be the major component to change the nutrition signpost labeling policy in the direction desired by the food industry. In addition, the absence of technical alternatives led to the bureaucracy working closely with industry. The conclusions suggest that the government should provide systematic tools with which to communicate with the public and make the risk analysis system more scientific and more open.

Objectives : This research was investigated to evaluate the psychological characteristics and changes of psychological state among dental orthodontic patients. Methods : This cross-sectional questionnaire research was conducted with 230 dental orthodontic patients in Busan from December 23, 2009 to March 6, 2010. The psychological analysis of dental orthodontic treatment patients was performed with Symptom checklist-90-revision(SCL-90-R) considering 5 general characteristics and 2 treatment period related characteristics. Estimated psychological results were changed T-score. Data analysis was performed with descriptive analysis, t-test and ANOVA using SAS(ver 9.1) program. Results : The levels of T-score of SCL-90-R were 43.88±7.50 in hostility(HOS), 43.38±4.64 in phobic anxiety(PHOB), 43.20±6.24 in somatization(SOM), 42.13±6.71 in paranoid ideation(PAR), 41.39±8.16 in interpersonal sensitive(I-S), 41.01±7.90 in obsessive-compulsive(O-C), 40.96±5.37 in psychoticism(PSY), 40.96±5.19 in anxiety(ANX) and 39.81±6.80 in depression(DEP), respectively. The T-score of phobic anxiety in before treatment group was higher than that of treatment groups. The T-score of interpersonal sensitive and paranoid ideation in over 36 months treatment period group were higher than that of other treatment period groups. Conclusions : Phobic anxiety(PHOB), interpersonal sensitive(I-S) and paranoid ideation(PAR) were affected in pre-treatment and long-term treatment dental orthodontic patients. Psychological management methods considering treatment period are needed to improve mental health of dental orthodontic patients.(J Korean Soc Dent Hygiene 2012;12(1):37-46)
