Objectives: This study aimed to assess the relationship between electric toothbrush use and the presence of community periodontal index (CPI) code calculus among Korean adults. Methods: Data from the 7th Korea National Health and Nutrition Examination Survey were analyzed. Multiple logistic regression analysis with a complex sampling design was conducted, adjusting for general characteristic factors. Analyses were performed using SPSS Statistics 29.0. Results: Among the participants, the prevalence of electric toothbrush users was 5.3%. Within this group, 4.7% had periodontal disease, whereas 5.9% did not (p=0.025). Even after adjusting for general characteristics factors in model II of electric toothbrush use, the odds ratio remained statistically significant at 0.791 (95% CI: 0.631-0.992) in all cases. Conclusions: Electric toothbrush use appears to be associated with potential benefits in managing the CPI code calculus distribution; however, evidence supporting this notion remains insufficient. The study findings suggest that these results could be a basis for future studies related to oral hygiene products and the design of oral health promotion programs.

The current study explored the factors that affect the addictive use of facebook. This study focused on the relationship between personal characters and the addictive use of facebook. To define the addictive use of facebook, various issues and the definitions of the Internet addiction were first considered in the theoretical background. Then depression, extroversion, openness, and communication competence were considered as the personal characters. Data were obtained by online survey and 600 responses were gathered. The results revealed that depression predicted the higher degree of the addictive use and low communication competence positively affected the addictive use of facebook. However, after controlling for communication competence, depression and extroversion were both associated the addictive use of facebook. Further, social compensation perspectives and social enhancement perspectives, and the policies on the SNS addiction were discussed.

Tunnel Mapper, which is tunnel face survey system was used to conduct Face Mapping on the face of the tunnel that is under construction. Then, accuracy and utility value on the forecast of discontinuity were verified to verify the field application in order to present the measures for the use of the system for conducting research on the discontinuity. As result of the directivity verification following discontinuity‘s project, forecasted measurement and actually researched measurement error for the Dip direction and Dip angle was less than ${\pm}10$. Accuracy was 82.6% for Dip direction and 90.7% for Dip angle, which are high. Accordingly, face research discontinuity forecasting system's reliability level towards directivity is high. Tunnel Mapper, a tunnel face survey system can be leveraged to replace face's visual survey and to obtain objective information, enabling execution of the survey system that can automate face survey going beyond time and space related limitations.

본 연구는 개별 선원들의 다양한 복지 욕구를 충족시키는데 중요한 역할을 담당하는 해운기업의 복지후생 실태를 조사해 보기 위하여 선원의 인적 특성과 승선근무 특성에 따른 복지후생 프로그램의 이용도를 분석하고, 이들 프로그램의 만족도가 회사에 대한 조직몰입도와 직무만족도에 미치는 영향을 검증하였다. 현재 승선 중인 선원 459명을 대상으로 조사 분석한 결과, 선원의 연령, 결혼여부, 직급, 승선기간, 회사 근속기간 등의 인적 특성과 승선근무 내성에 따라 복지후생 프로그램의 이용도에 차이가 있는 것으로 나타났다. 그리고 해운기업의 복지후생 프로그램의 이용에 따른 만족도가 높을수록 선원의 조직몰입도와 직무만족도가 높아지는 것으로 검증되었다.

Purpose: To identify user requirements for electronic nursing record (ENR) systems so as to ensure system usability. Methods: A mixed methods approach were applied in three steps : (i) task and workflow analysis with literature review of nursing documentation, (ii) literature reviews of system usability, and (iii) Use Case idenfication and consensus-based validation. We analyzed the nursing activity logs collected from a time-motion investigation of six hospitals. The Use Cases were validated by eight clinical experts from different hospitals and two experts from academia in a sequential Delphi survey. Consensus was achieved for the significance score and agreement among the panel. Results: Eight task groups and patterns of task flow were observed, which were translated into nine Use Cases. The specification of Use Cases was derived from principles, guidelines, and recommendations on nursing documentation and electronic health record systems, which was organized into three requirements of each Use Case: functionality, information, and design characteristics. Each Use Case achieved an agreement of 50~70%, and significance scores of 4 or 5 on a 5-point Likert scale. Conclusion: The nine Use Case identified were considered to be important and adequate in terms of both clinical and informatics contexts.

In many cases, the measurement error variances may be functions of the unknown true values or related covariates. This paper considers design-based estimators of the parameters of these variance functions based on the within-unit sample variances. This paper devotes to: (1) define an error scale factor $\delta$; (2) develop estimators of the parameters of the linear measurement error variance function of the true values under large-sample and small-error conditions; (3) use propensity methods to adjust survey weights to account for possible selection effects at the replicate level. The proposed methods are applied to medical examination data from the U.S. Third National Health and Nutrition Examination Survey (NHANES III).

Objectives : This study focused on examine the relevance between behavioral changes of customers and re-use intention on medical institution after experiencing infection control through external stimuli. Methods : This research was based on self-standing survey conducted from August to November 2010, 214 people who randomly selected from five dental clinics located in Busan were analyzed as the final group. Collected data were performed using SPSS 12.0 for Window. Results : 1. 82.8% of those surveyed who experienced external stimulation have changed their behavior on hospital environments and facilities, and 80.5% of them answered the stimuli influenced their re-use intention on medical institution. 2. There were no significant differences between participants by general characteristics on 'The reason why medical team wear sanitary appliances'. In age group 30~39, 85.4% of participants chose the answer so the difference were statistically significant(p<.001). Result by household income showed significant difference in group over $1,000 to $2,000 as 82.7% response(p<.05). 3. 94.4% of participants chose 'Required' for both surgical suits and gloves in research of 'The necessity level of personal sanitary appliances' which medical teams wear for treatment and 79.4% agreed that medical teams need to change their medical gloves whenever treating each patients. 4. The survey revealed that the most important appliance in patient's awareness were surgical gloves and protective goggles has chosen as the least important one. Conclusions : Patients as medical consumer were highly noticed of importance of the infection control in dental clinic and necessity of personal sanitary appliances. The patients who has accessed dental infection control information by external stimuli in advance showed objectival changes of their visit and behavioral changes with bringing medical environments together. This aspects influenced those patient's re-use intention in conclusion.

오늘날의 인터넷은 네티즌들에게 수많은 정보를 제공해 줌에 따라 이제는 본격적으로 인터넷을 통해 네티즌들의 생각을 수집해 가는 단계에 이르렀다. 이러한 상황에서 웹 설문조사는 오프라인뿐 만 아니라 온라인상에서 그 가치를 더 할 수 있다. 하지만 많은 사람들의 참여가 중요하기 때문에 설문조사는 사람들의 관심을 끌 수 있는 주제여야하고, 서술적인 평범한 화면보다는 가시적인 기능이 추가되어 흥미를 유발시키는 새로운 인터페이스를 제공해 줌으로서 네티즌의 보다 적극적인 관심과 설문조사에서의 높은 호응도를 이끌 수 있다고 본다. 이에 플래시를 이용한 웹 설문조사 시스템을 이용해서 재미있게 설문조사를 할 수 있게 함으로서 가치를 한층 더 높여 보고자 한다.
