  • Palatoplasty using Furlow's double-opposing Z-plasty has been performed from June, 1995 to September, 1999 at Seoul National University Children's Hospital. The goal of this study is to determine the optimal timing of repair and cleft severity affecting velopharyngeal function. This is the retrospective study of patients operated by the second author. The mean age of patients was 10.53 months. The patients could be divided into three groups-isolated cleft palate(n=70), unilateral cleft lip and palate(n=88), and bilateral cleft lip and palate(n=42). To evaluate the velopharyngeal function, we used two parameters, speech evaluation and cineofluorography using DSR(digital subtraction radiography). Also, to determine the relevance between cleft severity and speech development, we measured the distance between maxillary tuberosities and cleft margins. Among 200 patients, about 96% had no or minimal hypernasality and 87% had no or mild nasal emission. The cleft width and length of soft palate seemed not to be related with the speech development. Palatoplasty at the age under 12 months resulted in less 'nasal emission' and better 'articulation' of the parameters that were assessed at the age of 7 years. It can be concluded Furlow palatoplasty shows satisfactory results and also it seems that it is better to perform the operation before the age of 12 months.

  • Purpose: To develop an e-learning blood-borne infection control program and to evaluate the effects of the program on risk perception, knowledge, preventive health behaviors related to blood-borne infections, and satisfaction with the program by nursing student. Methods: The program was developed through the processes of analysis, design, development, implementation, and evaluation. The pre-experimental research design involved a one group pretest-posttest design. The setting was two universities located in Daejeon, Korea. Results: Using the program that was designed and developed, results for the total score of risk perception, knowledge, and preventive health behaviors in the post-test application were significantly higher than in the pre-test application (p<.05). Relevance and usefulness of the information received the highest ratings, while the system's design were demonstrated to have the lowest ratings. Those areas requiring correction were modified accordingly. Conclusions: Application of an e-learning blood-borne infection control program is effective, and can be expanded to other student nurses who also have a high risk of blood-borne infections.

  • Background: An important function of the regional public hospital is to satisfy the basic medical needs of the community through the stable provision of high-quality medical services. The purpose of this study was to identify the relevance index (RI) of the regional public hospital and to identify the factors that affect the RI. Methods: Data were obtained from the 2017 regional public hospital operation evaluation report and 2017 medical monitoring report for vulnerable area. RI of the regional public hospital was a dependent variable, and multiple regression analysis was performed with observed variables of medical supply-demand condition, medical supply, and medical supply structure. Direct effects and indirect effects were confirmed by the analysis of structural equation models (SEM) to see if there were mediating effects. Results: The RI was 13.1%, and the average of all percentage refined diagnosis-related group (RDRG) was 29.4%. Factors affecting RI were medical supply-demand conditions, medical supply, and medical supply structure. As a result of multiple regression analysis, RI was higher when high percentage RDRG of the regional public hospital (t=4.117, p<0.05), the size of regional public hospital location (t=-2.554, p<0.05), and the population of regional public hospital location (t =-2.415, p<0.05) were smaller. The results of the SEM analysis show that the higher the medical supply-demand conditions, the more direct effect of decreasing the RI and the indirect effect of decreasing the effect of reduction through the medical supply (direct effect=-1.322, total effect=-0.573, p<0.01). The higher the medical supply structure, the more direct effect on the RI (direct effect=1.047, p<0.05) and the higher the medical supply, the more indirect effect of RI through the medical supply structure (total effect=direct effect=0.619, p<0.05). Conclusion: It has been confirmed that the provision of medical services can affect the RI the regional public hospital which should be considered in carrying out future policies.

  • The purpose of this study was to analyze the relevance of the school science contents that have been implemented for the 7-10th grade students in Korea since 2001. To fulfill the purpose of the study, we 1) analyzed the 7th national science curriculum of Korea, California science standards, the national science curriculum of England, Japanese national science curriculum, and current Korean and Japanese science textbooks, 2) conducted a nationwide survey in order to gather opinions from students, teachers, and science specialists. The main findings of this research were as follows: First, the number of topics presented at each grade level should be reduced and similar topics and themes should be integrated for students' deeper understanding. Second, science contents were excessive compared to the allotted teaching time and to foreign countries. Thus, the excessive overlapping and repetition of science contents should be avoided among the primary, middle and high school level, and the number of science concepts and activities should be reduced to an appropriate level considering time allotment for science classes, teachers' workload, laboratory conditions, etc. Third, to cope with the decreasing students' understanding and interests in science as school level and school year goes up, the science curriculum and textbooks should be developed to allow for student to learn science concepts by solving problems confronted in their daily lives. Fourth, a differentiated curriculum such as in-depth and supplementary course should be described not in science contents, but in teaching and learning strategy.

  • It is not easy for business workers to find proper information for his job, because of the following problems:(1) information exist in various information system both internal and external with diverse formats(2) he cannot estimate relevance of all the information and (3) he cannot select proper information among large volume of information. The requirements for the systems are the following things:(1) search of relevant information from various internal and external information systems(2) proving an integrated view of information for workers, and (3) information processing and decision-making are seamlessly integrated fro business workers. We proposed an agent system to fulfill the requirements. We focus on the purchasing job, and developed a prototype system. PIPA(Purchasing Information Process Agent). The PIPA performs not only information processing jobs(information search gathering, display, business form -making)but also decision-making support job (evaluation of supplier candidates, and apply of sourcing policy) for sourcing manager. The framework of the PIPA can be appled to other information processing and desision-making jobs.

  • This study was carried out to evaluate the renewable energy dissemination programs in Korea, using peer-review. Especially, we used the peer review method which was suggested to evaluate the renewable energy program in U.S. by EERE, DOE. Before we implemented the peer review, we modified this method suitable for evaluating the renewable energy dissemination programs in Korea by getting advice from expertise in renewable energy policy. From this procedure, we have verified six evaluation criteria as Quality, Productivity, Accomplishments, Relevance and Management. We interviewed renewable energy policy expertise and corporation to evaluate the programs against these criteria. The result shows that overall programs were performed more than average. In addition, both the policy expertise and corporation perceived that "oan Guarantee Program" and "ompulsory Installation of Renewable Energy Facility in Public building" fulfilled its role to a great extent. However, the respondents pointed out that all of the programs need to be improved on its management.

  • Morinda citrifolia, also known as Great Morinda, Indian Mulberry, or Noni, is a plant belonging to the family Rubiaceae. A number of major chemical compounds have been identified in the leaves, roots, and fruits of the Noni plant. The fruit juice is in high demand in alternative medicine for different kinds for illnesses such as arthritis, diabetes, high blood pressure, muscle ached and pains, menstrual difficulties, headache, heart diseases, AIDS, gastric ulcer, sprains, mental depression, senility, poor digestion, arteriosclerosis, blood vessel problems, and drug addiction. Several studies have also demonstrated anti-inflammatory, antioxidant and apoptosis-inducing effects of Noni in various cancers. Based on a toxicological assessment, Noni juice was considered as safe. Though a large number of in vitro, and, to a certain extent, in vivo studies demonstrated a range of potentially beneficial effects, clinical data are essentially lacking. To what extent the findings from experimental pharmacological studies are of potential clinical relevance is not clear at present and this question needs to be explored in detail before an recommendations can be made.
