  • This study evaluates the effectiveness of the "Seoul Sanitation Grading System Evaluation Index" developed earlier and to analyze sanitation management practices in restaurants in Seoul, Korea. The categories evaluated were the food management standard, facilities/equipment standard, and essential checking items specified in the law. These items were graded and classified into A ($100{\sim}90$), B ($89{\sim}80$), C ($79{\sim}70$) and Score (less than 69) based on the criteria set by the present researchers. We randomly selected 56 restaurants in five local cities (Jung-gu, Seocho-gu, Jongno-gu, Songpa-gu and Yeongdeungpo-gu) and investigated each by actually visiting the site of business. The achievement rate for food management standard was 80.8%; as for the specific items in the category, it was the highest in food ingredients at 77.1% and the lowest in food storage at 62.1%. For the facilities/equipment standard, the achievement rate was 77.8%; as for the specific items in the category, it was the highest for vermin at 88.1% and the lowest for operation at 70.8%. The achievement rate for overall individual sanitary management was 70.7% and in the category, the lowest score was seen in hand washing at 57.1%. The overall average score of sanitation management practices using the Seoul Sanitation Grading System Evaluation Index in restaurants in Seoul was 73.7, which fell into the C category. As for the number of restaurants in each grade category, there were 10 (17.9%) in each category of A ($100{\sim}90$), B ($89{\sim}80$) and C ($79{\sim}70$) with 30 (53.6%) scoring higher than 70, whereas those scoring less than 69 included 26 (46.4%). The average scores for those restaurants designated by local governments (exemplary restaurants, general restaurants, best Korean restaurants in Seoul) were not significantly different; however, they were higher in franchises than those small restaurants ran by individuals.

  • It is suggested that evaluation of diet quality may be a great indicator of nutritional assessment. The aim of this study was to evaluate the diet quality of children and adolescents based on nutrient and food group intake and Diet Quality Index-International (DQI-I). This survey was conducted through questionnaires and diet record survey to 477 students (elementary school students; n = 131, middle school students; n = 136, and high school students; n = 210). The results showed that high school students were significantly more often to skip breakfast compared with the other groups. The middle and high school students consumed significantly higher intakes of food and energy compared to the elementary school students. Also the number of nutrients in Index of Nutritional Quality (INQ) < 1.0 of high school students were significantly higher than that of elementary and middle school students. The Korean's dietary diversity score (KDDS) of elementary school, middle school and high school students were 4.1, 4.4 and 4.3 respectively. The average DQI-I of elementary school, middle school and high school students were 66.7, 65.5, and 63.7, respectively and there was significant difference. Also, middle school students showed to have higher score in variety and adequacy category compared with the other groups, and elementary school students appeared to have higher score in moderation category. In conclusion, high school students appeared to have unhealthy dietary habits in terms of high frequency of skipping breakfast and lower INQ and DQI-I score compared to the elementary school and middle school students. Therefore, the proper dietary management should be needed for high school students.

  • 기존의 무기준 동영상 화질 평가는 디코딩 픽셀 단에서 평가와 전송 에러를 고려한 비트스트림단에서 화질 평가 방법으로 나눌 수 있다. 기존의 방법은 추가 데이터 필요하고 복잡도와 평가 정확도등의 문제가 있어 실제적인 실시간 화질평가에 적용하기에 문제가 많다. 본 연구에서는 실시간 비디오 전송 환경에서 이용될 수 있는 간단하면서도 정확도가 높은 무기준법 화질 평가 방법을 제안한다. 본 논문에서 제안된 무기준법 화질평가 방법은 양자화 파라미터, 전송에러정보, 움직임 벡터정보를 이용한다. 제안된 방법을 검증하기 위해서, ITU-T P.910 ACR(Absolute Category Rating)을 사용하여, 기존의 전체 기준법과 주관적 화질 평가 대비의 상관도를 비교하였는데 제안방법이 85%이상의 상관도를 보여 주었다.

  • Objectives: The aim of this study was to assess the quality of the information and characteristics associated with information packaging, and develop suggestions for how this web site might be improved. Methods: The 50 sites were selected for evaluation. Inclusion criteria for evaluation were the purpose and the popularity of the sites. Two kinds of evaluation tool were employed for the analysis: one that evaluate the quality of information and the design of the web sites, and another that evaluate the covered contents. A scoring system allowed the sites point on yes/no basis on the evaluation items. The association between quality of the web sites on sexuality education and their site characteristics were assessed using ANOVA. Conclusions: Major conclusions were as follows. First, the scope and currency of the selected web sites were found to be appropriate. Second, the authority of the information was found to be the most serious problem of the selected sites. Third, the category of sexual behavior found to be the most frequently mentioned and sexual health was the second. The least mentioned category was personal skills. Finally, sites operated by private organization were found to have more accurate information and better design feature than those operated by public organization and/or individual.

  • The fine-tuned neural network (NN) model for a whole temporal portion in a video does not always yield the best quality (e.g., PSNR) performance over all regions of each frame in the temporal period. For certain regions (usually homogeneous regions) in a frame for super-resolution (SR), even a simple bicubic interpolation method may yield better PSNR performance than the fine-tuned NN model. When there are multiple NN models available at the receivers where each NN model is trained for a group of images having a specific category of image characteristics, the performance of Quality enhancement can be improved by selectively applying an appropriate NN model for each image region according to its image characteristic category to which the NN model was dedicatedly trained. In this case, it is necessary to signal which NN model is applied for each region. This is very advantageous for image restoration and quality enhancement (IRQE) applications at user terminals with limited computing capabilities.

  • Purpose: This study was conducted to examine mother-child interactions and the quality of life of preschool children with epilepsy as perceived by mothers, and to investigate the relation between mother-child interactions and the quality of life of preschool children with epilepsy. Methods: Participants for this study consist of 92 mothers of children with epilepsy aged three to six years who were treated at university hospitals and a city hospital located in Seoul, Korea. The instruments used for this study were mother-child interactions of preschool children scale and the Korean version of the TAPQOL (TNO-AZL Preschool children Quality of Life). Results: The level of mother-child interactions for preschool children with epilepsy showed a mean score 125.91. The category of dyadic domain was rated the highest while the child domain category was rated the lowest. The level of mother-child interactions for preschool children with epilepsy showed a significant difference according to the mother-child relationship, birth history, seizure frequency, number of antiepileptic drugs and combined disabilities. The quality of life of children with epilepsy showed a significant difference according to the mother-child relationship, birth history, seizure frequency, number of antiepileptic drugs and combined disabilities. There is a statistically significant positive correlation between mother-child interactions and quality of life of preschool children with epilepsy. Conclusion: This study suggests that the mother-child interaction of preschool children with epilepsy showed a tendency to be led by mothers. In order to stimulate mother-child interactions, mothers should help their children enhance their reaction and participation.

  • In this study, a correlation between execution of quality management activities and their results was verified by applying the Malcolm Baldrige model (hereafter referred to as the MB model) as a quality management performance measurement indicator for small and medium enterprises (SMEs) in South Korea. To achieve this goal, we need to determine whether the categorical requirements in the MB model are recognized consistently in SMEs, as a prerequisite. To this end, factor analysis was conducted for measurement variables in each category, which revealed that the process indicator was made up of six factors and the outcome indicator was made up of five factors, like those configured in the MB model. This result can be interpreted to mean that the requirements in each category of the MB model were well produced and recognized consistently throughout SMEs in South Korea. In addition, the analysis of causality between the process indicator (quality management activities) and the outcome indicator (management results) showed high causality between them. Although the quality management levels of SMEs in South Korea are inferior to those of conglomerates or other national quality award-winning companies, this study is significant in that the causality between quality management activities and results was verified, since this study targeted SMEs in South Korea as the target of investigation. Thus, it is empirically proven that the MB model can contribute to improved management results for SMEs in Korea.

  • Purpose: The purpose of this study was to define the core components required of nurses to provide quality nursing care to patients and analyze the significance of these components in the hospital's various units to maintain a high level of competence among nurses. Method: The study evaluated 3 categories included 35 subcategories with 148 core components that were derived from literature review and interviews of nursing professionals. The nursing professional category included 18 subcategories with 98 components, the organizational culture category included 4 subcategories with 16 components, and the temperament-attitude category included 13 subcategories with 34 components. The study included 335 nurses with more than one year of hospital experience and measured disparities among different hospital units. The data was analyzed with SPSS-Win 10.0, differing perceptions of the importance of general traits among the participants were measured using standard deviation, and differing perceptions of the importance of professional traits among the participants were assessed using ANOVA and subsequently with the Bonferroni Test. The reliability of the aforementioned research tools were evaluated using the Cronbach's ${\alpha}$. Result: The results of the study were as follows: 1. Among the three categories, temperament-attitude category was perceived to be the most important, followed by nursing professional category and organizational culture category. Among the ten most important subcategories within the three categories, safety and infection prevention as well as responsibility were perceived to be the most important, followed by promotion of physiologic adaptation, document management and presentation, self-control, ethics, observance law, coping with emergency, humanity, and medication. 2. The relative importance of category associated with the core competencies within the hospital unit were as follows : 1) The units that rated nursing professional category as being the most significant were: internal medicine, surgical unit, mother-child unit, emergency room, intensive care unit, and operating room, in that order. 2) The units that rated the organizational culture competencies as being the most significant were: mother-child unit, internal medicine, surgical unit, emergency room, operating room, and intensive care unit, in that order. 3) The units that rated temperament-attitude category as being the most significant were: internal medicine, surgical unit, emergency room, mother-child unit, operating room, and intensive care unit, in that order.
