Objectives: The purpose of the study is to investigate the awareness and attitude toward health insurance coverage extension to scaling in dental service consumers. Methods: A self-reported questionnaire was completed by 349 adults in Jeonbuk from May 4 to 15, 2015. The questionnaire consisted of general characteristics of the subjects (7 items), Awareness of the dental health insurance system(8 items), Health insurance system coverage extension to scaling(8 items), Self-perception of oral health(7 items), Recognition toward yearly scaling benefit(10 items). Results: There were significant differences according to age in opinions on the appropriateness of the frequency of yearly scaling benefit, and the respondents who were in their 20s, who were unmarried and who brushed their teeth three times a day had significantly different opinions on the appropriateness of the fee of yearly scaling benefit. Their opinions on the expansion of scaling benefit was significantly affected by age. It implies that scaling should be added to the coverage list of the national health insurance in every age group since there is an increase in periodontal diseases with age. Concerning awareness of dental health insurance policy, the better-educated respondents took a better view of this system as they showed a more positive interest in its policies and shifts. Conclusions: It is desirable to provide more precise information as to eligible age, frequency and cost through public promotion of health coverage of scaling, and the effort to improve the health insurance coverage policy should be made in order to extend the scope of health coverage of scaling in the near future.

Objectives. The purpose of this study was to evaluate the quality of abstracts of original articles. Methods. This subjects selected total 63 abstracts of the original articles of the Korean Journal of Preventive Medicine in 1997. The quality of abstracts was measured against a checklist of evaluation criteria, which were divided into eight categories and the numbers of inappropriate words (including grammar) according to criterionbased survey. A score for each abstract was obtained by dividing the number of criteria presented by the number applicable. The overall mean score was also determined. Results. The overall mean score of abstract quality was 0.55 out of 1. Of the abstracts subject selection 83% didn't include specific technical descriptors. Of those that gave conclusions 92% didn't address study limitations and 78% made no recommendations for future study. The overall mean number of inappropriate usage of words (including grammar) per abstract was 14.1. The overall mean number of English words was 283. In the multiple regression analyses, the research career of the first author and the number of English words to the number of inappropriate usage of words were statistically significant. Also, in the secondary regression model, the number of English words to the quality score of abstract was only statistically significant. Conclusions. Most of the abstracts provided some information pertaining to each evaluation criterion. However, they did not provide sufficient details to enhance the reader's understanding of the article. On the basis of the study the abstracts need improvement in its description of the reported subject selection, statements of limitations and recommendations, etc. The Korean Society for Preventive Medicine will recommend a proposal for more informative abstracts in Korean J Prey Med and will take into consideration the introduction of foreign review of abstracts. Future studies should address these issues and compare the quality of abstracts between different journals and their time of publication.

Background: Currently, the number of patients visiting pain clinics is increasing with the augmented concerns of the patients about management of pain. We conducted this study in order to comprehend the characteristics of the patients visiting pain clinics and to find a method to further raises the public's awareness about pain treatment. Methods: We surveyed 497 new patients who had visited pain clinic of Kyungpook national university hospital from August 1998 to July 1999. We analysed these patients about their age, sex, chief complaint, duration of pain complaints, resident district, educational level and route of visiting pain clinic by use of questionnaire. Results: In age distribution, the largest proportion (29.8%) were in their 60's. Low back pain was the most common chief complaint (33.0%), the highest (43.7%) percentage of patients had complained of pain for over 6 months. Two thirds of the patients lived in urban area. Patients who were educated to only elementary school level made up the largest group with 35.3%. Referrals from former patients who had visited our pain clinic and had received treatment. Conclusions: As increasing patients who have pain complaints are related to social advanced age, it is prudent to consider the characteristics of age related pain complaints. And we have to guide the pain patients to have more earlier treatments using mass media because there is still insufficient general information about pain clinic and pain managements.

본 연구에서는 오차항이 AR(1)을 따르는 회귀모형에서 올바른 추론을 도출하고자 모형식별의 문제를 다루었다. 이를 위해 Box-Cox 변환된 회귀모형을 고려하여 (i) Box-Cox 변환모형과 AR(1) 오차에 대한 동시 검정, (ii) AR(1) 오차가 존재하는 모형에서의 Box-Cox 변환모형에 대한 검정 그리고 (iii) 모형이 Box-Cox 변환되어 있을 때 오차가 AR(1) 과정을 따르는지에 대한 LM 검정통계량을 유도하였다. 특히 LM 검정방법에서 여러개의 모수가 비선형관계를 형성하고있어 정보행렬의 추정은 계산상 매우 어렵다. 따라서 정보행렬의 원소에 대한 기대값을 구함에 있어 Taylor전개를 이용하여 정보행렬을 구하고 이에 기반을 둔 LM 검정통계량($LM_E$)를 제안하고 모의실험결과 $LM_E$가 기존의 헤시안행렬에 기반을 둔 LM 검정통계량($LM_H$)에 비하여 유의수준을 잘 유지하고 있는 것으로 나타났다.

In smart era, concept of User experience has been an important issue both in academic and practical areas in recent years. Interactive space became one of the major design paradigms. For elevating the interactive effect, we need user?centered design methodology which uses the influential factors on the interactivity. As, well developed information technology made a lot of changes to various fields of our society, interactive space with the concept of HCI became a big issue in environmental design field. In this interactive space, various types of informative factors of the given space are sent using sensor and computer networking technology to the main system. So, a user's movement in the space in more than just a movement itself-user's movement now forms a important spatial structure that leads the narrative of the space. in this research, I will come up with the problems that the interactive space has right now, and analyze what the public space must have, and combine them with interactive space by HCI theory. architecture space is not the old space adapting digital technology. In order to take the role as new space paradigm. environment and technology, it has to develop technology continuously and experimental space at the same time. It must have co-evolution of architecture space field and others through organic network. by that, the evolution of space will be in the way that combines space which is responded to human emotion and user centric human friendly.

Objectives : The purpose of this study was to examine the factors related to the dental caries and periodontal diseases of Korean elderly people in terms of demographic characteristics, oral health promotion behavior and systemic diseases in an effort to provide information on national policy setting and policy evaluation about the prevention of tooth loss resulting from severe oral diseases and the promotion of elderly people's oral health. Methods : The first-, second- and third-year raw data of the 4th National Health and Nutrition Survey were utilized, and the data of 3,882 elderly people who got a dental checkup were analyzed. The statistical package SPSS WIN 19.0 was employed to make a logistic regression analysis. Results : The senior citizens who did toothbrushing less frequently were more likely to have dental caries. As for periodontal diseases, the men were 1.34-fold more likely to have periodontal diseases than the women, and the respondents whose self-rated health state was worse were 1.40-fold more likely to have periodontal diseases than the others whose self-rated health state was better. The senior citizens who ever received treatment from unqualified people were 1.30-fold more likely to have peridontal diseases, and those who took neither vitamin compound nor minerals were 1.30-fold more likely to have periodontal diseases. Those who suffered from low High-density Lipoprotein cholesterol(HDL) were 1.35-fold more likely to have periodontal diseases than the others who didn't. Conclusions : Those whose self-rated health status is worse should especially be concerned about periodontal diseases. Specifically, it's needed to pay attention to the low-income classes, and the government should take measures to provide quality welfare services for elderly people not to receive treatment from unqualified people. Besides, research efforts should be made to determine the relationship between periodontal diseases and low HDL-cholesterolemia.
