Background: Dental anxiety in children is a major barrier in patient management. If dental anxiety in pediatric patients is assessed during the first visit, it will not only aid in management but also help to identify patients who are in need of special care to deal with their fear. Nowadays, children and adults are highly interested in multimedia and are closely associated with them. Children usually prefer motion pictures on electronic devices than still cartoons on paper. Therefore, this study was conducted to evaluate a newly designed scale, the animated emoji scale (AES), which uses motion emoticons/animojis to assess dental anxiety in children during their first dental visit, and compare it with the Venham picture test (VPT) and facial image scale (FIS). Methods: The study included 102 healthy children aged 4-14 years, whose dental anxiety was measured using AES, VPT, and FIS during their first dental visit, and their scale preference was recorded. Results: The mean anxiety scores measured using AES, FIS, and VPT, represented as $mean{\pm}SD$, were $1.78{\pm}1.19$, $1.93{\pm}1.23$, and $1.51{\pm}1.84$, respectively. There was significant difference in the mean anxiety scores between the three scales (Friedman test, P < 0.001). The Pearson's correlation test showed a very strong correlation (0.73) between AES and VPT, and a strong correlation between AES and FIS (0.88), and FIS and VPT (0.69), indicating good validity of AES. Maximum number of children (74.5%) preferred AES. Conclusion: The findings of this study suggest that the AES is a novel and child-friendly tool for assessing dental anxiety in children.

Objectives: Knowledge, attitudes, and practices of healthcare providers related to occupational exposure to bloodborne pathogens were assessed in a tertiary-care hospital in Middle East. Methods: A cross-sectional study was undertaken using a self-administered questionnaire based on 3 paired (infectivity known vs. not known-suspected) case studies. Only 17 out of 230 respondents had an exposure in the 12 months prior to the survey and of these, only 2 had complied fully with the hospital's exposure reporting policy. Results: In the paired case studies, the theoretical responses of participating health professionals showed a greater preference for initiating self-directed treatment with antivirals or immunisation rather than complying with the hospital protocol, when the patient was known to be infected. The differences in practice when exposed to a patient with suspected blood pathogens compared to patient known to be infected was statistically significant (p < 0.001) in all 3 paired cases. Failure to test an infected patient's blood meant that an adequate risk assessment and appropriate secondary prevention could not be performed, and reflected the unwillingness to report the occupational exposure. Conclusion: Therefore, the study demonstrated that healthcare providers opted to treat themselves when exposed to patient with infectious disease, rather than comply with the hospital reporting and assessment protocol.

디지털 콘텐츠를 사용자 개인별로 차별화하여 서비스하는 방법들이 다양하게 연구되고 있다. 연관규칙 탐색은 디지털 콘텐츠 서비스에서 각 개인의 선호도를 발견하는데 유용한 방법이다. Apriori 알고리즘은 빈발항목집합을 이용한 연관규칙 알고리즘으로 유용하게 사용되고 있다. 그러나 Apriori 알고리즘은 각 콘텐츠의 참조횟수만을 고려하기 때문에 상용 콘텐츠 서비스에서 나타나는 개인의 실제적인 선호도를 반영하기 어렵다. 본 논문에서는 콘텐츠별 구매이력과 사용시간을 기반으로 연관규칙을 탐색하는 Apriorir기반의 알고리즘을 제안한다. 제안하는 알고리즘은 빈발항목을 선택할 때 구매여부에 따른 가중치 값을 가지는 사용시간을 활용한다. 이러한 방법을 통하여 실제 사용자의 정확한 선호도를 파악할 수 있다. 제안된 알고리즘을 구현하고, 실제 콘텐츠 서비스 시스템에서 나타난 실제 데이터를 통하여 성능을 검증한다.

The conservation of stream habitats has been gaining more public attention and fish habitat suitability index (HSI) is an important measure for ecological stream habitat assessment. The fish habitat preference is affected not only by physical stream conditions but also by water quality of which HSI was not available due to the lack of field data. The purpose of this study is to estimate the HSI of Zacco platypus for water quality parameters of water temperature, dissolved oxygen (DO), and biochemical oxygen demand (BOD) using the water environment monitoring data provided by the Ministry of Environment (ME). Fish population data merged with water quality were constructed by spatio-temporal matching of nationwide water quality monitoring data with bio-monitoring data of the ME. Two types of the HSI were calculated by the Instream Flow and Aquatic Systems Group (IFASG) method and probability distribution (Weibull) fitting for the four major river basins. Both the HSIs by the IFASG and Weibull fitting appeared to represent the overall distribution and magnitude of fish population and this can be used in stream fish habitat evaluation considering water quality.

This study aimed to systematically adjust rural area development projects that have been carried out by a variety of government departments for activation of rural areas and overcome inefficient problems caused by the policies and projects promoted separately. As its alternative, this study aimed to explore efficient improvement scheme of rural villages associated with various projects. Major agriculture/rural policies and projects that have been promoted were classified by the target space of the policies and projects as Environment space, living space, and production space. Each space was categorized into five sub-items without duplication. By assessment results of rural area improvement level and preference by Analytic Hierarchy Process(AHP) method, maintenance of rural areas was classified into four types. And outer space structure was analyzed by using Space Syntax Method(SSM). Based on the analysis result above, facilities for improvement of rural villages were placed around representative facilities. Facility allocation was based on selection and concentration in terms of facility maintenance and on type attributes in terms of spatial aspects. And finally, alternatives schemes for setting up the basic direction of improvement of rural villages are local area characteristics and environmentally conscious business plan.

The objectives of this study was to investigate the incidence and any correction between hemiplegia with pusher syndrome and neuropsychological symptoms such as hemineglect and anosognosia. Pusher syndrome defines that the patient leans toward the hemiplegic side regardless of the position that patient was placed on and resists any attempt for passive correction of posture that would move his weight toward the midline of the body. The subjects of this study were 69 acute hemiplegia who had been rehabilitated at department of rehabilitation medicine, Asan Medical Center from May 1. 1999 through July 31. 1999. The data were analyzed by researchers who were trained for assessment of anosognosia and hemineglect. 12 subjects were excluded for confusion. The method of statistical analysis used for our study was Fisher's exact test. Results of the study disclosed 21 hemiplegia(38.6%) with pusher syndrome. In conclusion, these hemiplegic patients with pusher syndrome did not have any correlation with hemineglect and anosognosia and also had no preference of stroke side.
