  • The purpose of this research is to study the perception of mathematical creativity through gifted elementary mathematics students. The analysis on perception for mathematical creativity was done by testing 200 elementary school students in grades 4, 5, and 6 who are receiving gifted education in elementary mathematics gifted class operated by ${\bigcirc}{\bigcirc}$ City Dept of Education through the questionnaire that was developed based on Rhodes' 4P theory. This survey asked them to name what they think is the most creative from educational programs they have as far received. Then we analyzed the reason for the students' choice of the creativity program and interviewed the teachers who had conducted chosen program. As a result of analyzing the data, these students chose as mathematical creativity primarily creative problem solving, task commitment, and interest in mathematics in such order. This result is explained through analyzing the questionnaire that was based on Rhodes' 4P theory on areas of process, product and press. The perception of mathematical creativity by the gifted mathematical students not only helps to clarify the concept of mathematical creativity but also has implication for future development for gifted education program.

  • The era of Web 2.0, which is the web environment that offers end user oriented web platform, has arrived. Moreover, as the interest in UCC (User Created Contents) environment increases, it is a fact that the involvement of the users in multimedia contents is increasing rapidly. When the aim of Web 2.0, i.e. active involvement of the user, is considered, the necessity and the understanding about accessibility problem of the people who have difficulties about accessing web information, such as elderly and visually handicapped people, is increasing as well. This research analyzes the problems of virtually handicapped users to access web-based UCC services, and proposes an efficient implementation plan for a web-based UCC service that enables smooth access for them. Especially, the validity of the proposed method was verified by comparing the reaction time of the visually handicapped users with that when using the existing UCC services, through the implementation of the test page according to the plan proposed in this research.

  • We analyze the problem that is occurring when using parity mode transformation required for 9 bit serial communication under Linux environment and propose the solution. The parity mode change is used for 9 bit serial communication in the Linux that by nature supports only 8 bit serial communication. delay (around OS tick) arises. Our analysis shows that the cause is minimum length of waiting time to transmit data remained in Tx FIFO buffers. A modified Linux serial driver proposed in this paper decreases the delay less than 1ms by using accurate time delaying. Despite various system communication interfaces, enormous existing standards and system have adopted RS-232 serial communication, and the part of them have communicated by 9bit serial.

  • Cadastral parcel objects as polygons are fundamental dataset which represent land administration and management of the real world. Thus it is necessary to assure topological seamlessness of cadastral datasets which means no overlaps or gaps between adjacent parcels. However, the problem of overlaps or gaps are frequently found due to non-coinciding edges between adjacent parcels. These erroneous edges are called uncertain edges, and polygons containing at least one uncertain edge are called uncertain polygons. In this paper, we proposed a new algorithm to efficiently search parcels of uncertain polygons between two adjacent cadastral datasets. The algorithm first selects points and polylines around adjacent datasets. Then the Constrained Delaunay Triangulation (CDT) is applied to extract triangles. These triangles are tagged by the number of the original cadastral datasets which intersected with the triangles. If the tagging value is zero, the area of triangles mean gaps, meanwhile, the value is two, the area means overlaps. Merging these triangles with the same tagging values according to adjacency analysis, uncertain edges and uncertain polygons could be found. We have performed experimental application of this automated derivation of partitioned boundary from a real land-cadastral dataset.

  • Myocardial ischemia-reperfusion injury is a medical problem occurring as damage to the myocardium following blood flow restoration after a critical period of coronary occlusion. Oxygen free radicals (OFR) are implicated in reperfusion injury after myocardial ischemia. The antioxidant enzyme, Cu, Zn-superoxide dismutase (Cu, Zn-SOD, also called SOD1) is one of the major means by which cells counteract the deleterious effects of OFR after ischemia. Recently, we reported that a PEP-1-SOD1 fusion protein was efficiently delivered into cultured cells and isolated rat hearts with ischemia-reperfusion injury. In the present study, we investigated the protective effects of the PEP-1-SOD1 fusion protein after ischemic insult. Immunofluorescecnce analysis revealed that the expressed and purified PEP-1-SOD1 fusion protein injected into rat tail veins was efficiently transduced into the myocardium with its native protein structure intact. When injected into Sprague-Dawley rat tail veins, the PEP-1-SOD1 fusion protein significantly attenuated myocardial ischemia-reperfusion damage; characterized by improving cardiac function of the left ventricle, decreasing infarct size, reducing the level of malondialdehyde (MDA), decreasing the release of creatine kinase (CK) and lactate dehydrogenase (LDH), and relieving cardiomyocyte apoptosis. These results suggest that the biologically active intact forms of PEP-1-SOD1 fusion protein will provide an efficient strategy for therapeutic delivery in various diseases related to SOD1 or to OFR.

  • Purpose: In spite of many Healthy Cities projects in Korea, there are few research about healthy urban planning. So we tried to use available recent models to a Healthy Cities project in a medium sized city in Gyeongnam province. Methods: Using mainly European Healthy Urban Planning Model and opinion leader survey, SWOT analysis, forum and discussion have been done to a city. Secondary city health indicator obtained from Ministry of Statistics. Results: There are strong need to develop health industry, green traffic and healthy living from survey using Healthy Cities policy direction of Korean Health Promotion Fund. Among the Healthy Urban Planning objectives, improvements of physical environments, prevention of accidents and crime, improvements of healthy esthetics rated highly. Although environmental pollution was problem local government push forward to the pilot healthy urban project as active healthy water-front development. Considering secondary healthy city indicators, change of external forces and internal capacity final task for healthy urban planning for Yangsan city were development of riverside physical education park and active living and anti-ageing environments etc. Conclusions: Comprehensive assessment and plan was possible through MAPP Model using European Healthy Urban Planning objectives to draw the direction of future urban planning for Healthy Cities Projects. Further research and formal introduction would be needed.

  • Objectives: This study investigated Korean public's beliefs on helpfulness of various resources and preferred ways of addressing symptoms of mental health problems. Methods: A household survey was conducted on a stratified sample of adults aged between 18 and 74 (N=1,584). The participants were asked to provide their opinion on helpfulness of 39 resources for problems presented in the vignette, either depression(DEP) or schizophrenia(SPR). Descriptive statistics and factor analysis were conducted to summarize their opinion and to identify the underlying structure of beliefs about helpfulness of various resources. Results: Counselors/psychologists/social workers, family, psychiatrists, other therapists, and religious leaders were believed to be the most helpful. Methods that require one's initiatives marked percentages much higher than those of 'waiting to get better' or 'dealing with it alone'. The percentages for medications were lower than other methods in general, but higher than those of a western sample especially on antidepressants and anti-psychotics. Psycho/social approach was favored more for SPR than for DEP, and popular/cultural approach was favored much more for DEP than for SPR; physical/medical approach was strongly unfavored against DEP. Conclusion: Strategies need to be developed for utilizing various helpful resources to diversify modality of mental health services and facilitate referrals and gatekeeping. The differences in beliefs on helpfulness of various methods between DEP and SPR point to the need for problem-specific strategies.

  • The child sexual abuse is a serious social problem. The children are to seek the physical ability for protecting the mselves from crime. However there is no effective prevention program for that. The reason why the lack of understanding of society and the people's attitude as a fence sitter provoke in a roundabout way to the child sexual abuse. Thus this these conducted a survey research about the child sexual abuse for the common citizen. The questionnaire s were analyzed and composed of a frequency analysis and a cross-tabulations by using the tool SPSSWIN. The res ult was that the crime for child was often occurred nearby school and any effective prevention system.
