We present a B-spline fitting method based on genetic algorithm for the extraction of object contours from the complex image sequence, where objects with similar shape and intensity are adjacent each other. The proposed algorithm solves common malfitting problem of the existing B-spline fitting methods including snakes. Classical snake algorithms have not been successful in such an image sequence due to the difficulty in initialization and existence of multiple extrema. We propose a B-spline fitting method using a genetic algorithm with a new initial population generation and fitting function, that are designed to take advantage of the contour of the previous slice. The test results show that the proposed method extracts contour of individual object successfully from the complex image sequence. We validate the algorithm by false-positive/negative errors and relative amounts of agreements.

Background : Henoch-Schonlein purpura is a small-vessel vasculitis characterized by palpable purpura, abdominal pain, hematuria, and arthalgia. The exact etiology remain unknown despite a long and intensive research, but the findings showes immune mechanism is involved in the pathogenesis of this disease. The main clinical manifestations are skin rash, abdominal symptoms, joint symptoms, and renal involvement. And the existence of renal involvement influences on the course and prognosis of the Henoch-Schonlein purpura Objective : To demonstrate the therapeutic effect of herbal medicine(Kamiguibiondamtang) on parents with Henoch-Schonlein purpura Method : We treated two cases of Henoch-Schonlein purpura in a nine-year old male and a twenty-year old female, who showed multiple petechiae and ecchymoses on both extrimities with Kamiguibiondamtang. Result : A nine-year old male recovered completely and a twenty-year old female improved. Conclusion : We repert that we had good effects of herbal medicine treatment on two cases of Henoch-Schonlein purpura.
This study has been conducted to provide the basic materials about the occurrence structures, causes and choice of treatments of the traffic accident offenders' PTSD(Posttraumatic Stress Disorder). The results of this study can be summarized as follows. First, accident offenders', not victims', PTSD conditions, which has been only estimated until now, are measured by nationwide questioning survey. Second, accident offenders' changes of driving attitude after accidents could be typed by factors analysis in the 20 driving situations closely connected to the occurrence of traffic accidents. Third, by the t-test, the difference of driving attitudes in primary driving situations according to existence of PTSD is distinguished. Six driving situations, which are found significant by t-test, are applied to structural equation. So the variables related to PTSD and the models which analyze the attitude changes of driving are constructed. This study provides the basic materials to help the reduction and prevention of the occurrence of PTSD.
This research analyzed. knowledge structure and its effect factor by analysis of co-author and keyword network in Korea's health policy and administration sector. The data was extracted from 339 articles listed in the Korean Journal of Health Policy and Administration, and was transformed into a co-author and keyword matrix. In this matrix the existence of a link was defined by impact factors which were calculated by the weight value of what the role was and the rate of how many authors contributed. We demonstrated that the research achievement was dependent on the author's status and network index. Analysis methods were neighborhood degree, correspondence analysis, multiple regression and the difference of weight distribution by research fields. Co-author networks were developed as closeness centrality as well as degree centrality by a few high productivity researchers. In particular, power law distribution was discovered in impact factor and research productivity. The effect of the author's role was significant in both the impact factor calculated by the participatory rate and the number of listed articles. Especially, this journal shared its major researchers who had a licensed physician with the Journal of Preventive Medicine and Public Health. Therefore, social scientists were likely to be small co-author network differently from natural scientists. It was so called 'two cultures' phenomenon. This study showed how can we verified academic research structure existed in the unit of journal like as citation networks. The co-author networks in the field of health policy and administration had more differentiated and clustered than preventive medicine and epidemiology fields.
For the matter of elevator, one of the multi-use facilities for unspecified public, the JIS has re-established and reformed to apply to the environment in South Korea for the past 20 years. In the aspect of safety assurance, it was inevitable to suggest improved measures. The government, Ministry of Public Administration and Security has secured the safety by enhancing the safety management functions in the elevator inspection standards and expanding its safety device measures. Further, the international inspection standard has been introduced, which is about unifying inspection standard system into the international standard code. In March 14th 2012, the international standard (EN) has been amended and fully announced. Escalator and passenger conveyor among lift devices have several common danger factor that cause safety accident. First, the accident caused by decreased braking power of brake. Second, the accident caused by the rate difference between handrail and tread-board. Third, the accident caused by defects of contraflow preventing device or carelessness inspection. Fourth, the accident caused by wet tread-board or wet floor of platform which makes passenger slip and fall. As the improvements to prevent and reduce these negligent accidents, the inspection list to check and methods should be subdivided and applied for each accident likelihood cause for safety management enhancement and safety assurance of existing escalator and passenger conveyors. The escalators and passenger conveyors without safety devices in existence should be obliged to modify the part of the system or install additional safety device. With making these measures obligations, it requires to improve the system to be suitable for the international inspection standard and to have measures to prevent safety accidents. It also needs to arrange improvements for skid accident of tread-board by the external environment factors such as snow and rain.
$21^{st}$ century post digital society orients co-existence, fusion, and blurring boundary than conflict, differentiation, and boundary, and makes a try liberal combination of various different objects. Furthermore, radical development of science and digital equipments offer technical possibility that could combine various fields. Hence, many different departments demolish their boundary, and combine for development of multi-functional and complex shape's products. For job-nomads, fashion attempts to combine with architecture, furniture, daily necessities, and digital equipments spontaneously. This paper aims at consideration about the blurring phenomena expressed in complex fashion space of $21^{st}$ century throughout empirical fashion photographs analysis, which show combination among fashion and various different fields. Blurring boundary phenomena of complex fashion space are classified with 4 parts as follows as: 1) furniturizing, 2) wearable dwelling, 3) lumiduct, 4) becoming fashion. Each parts are examined 8 aesthetical characteristics such as movement and lightness, hyper-link and openness, immateriality and inter-activeness, and diversity and ambiguity. $21^{st}$ century fashion has changed more simple and light, and creates new form throughout combination with many other fields, and enlarges its function and sphere. I think this paper would help certificating practical use of fashion space as multiple and complex space, and makes contribution to forecast about fashion development of the future and offer inspiration about creative and innovative fashion design.
ADR program is designed to solve the problem such as the increase of suits and decision delayed. ADR program has the several significances, decreasing inappropriate cost as time and burden of courts, providing an approachable measure of relief and more efficient tool for settlement of dispute. Particularly ADR program satisfies the needs Intellectual property disputes need specialists that are versed in the subjected problem and, need to be souled quickly in confidence. And parties concerned are not good at the strict judicial procedure in courts, At this point, ADR program holds some advantages over court proceeding for intellectual property disputes. Specialists can be selected as arbitrators or mediator; Cofidentiality may be preserved; Flexibility allows settlement based on mutual commercial interests; Single solution is possible for multiple disputes involving parties from different countries. However, ADR program has not been properly used in. Korea, which is due to not only the lack of understanding the ADR program, but the poor number of filings and settlements. Intermediaries are not professional and also they do not take active hands in disputes. Sometimes, their fairness is asked as peacemakers. Eventually, it is said that this program is not enough to settle international disputes. To activate the ADR program, we can propose the ADR program annexed to court for example. And we can introduce the conciliation and arbitration to disputes in intellectual property. Traditionally arbitration has been a crucial issue in intellectual property disputes. In that intellectual property rights are granted by the local sovereign power, many legal systems in the past maintained the position that the existence, extent, meaning and application of such rights could only be definitively decided by the granting authority or the courts of that country. There is wide recognition that the arbitration of intellectual property is desirable. The law in most of the major countries has been changed in recent years in favor of arbitrability of intellectual property rights. We can also propose ADR on-line.
Self-incompatibility in Brassica campestris is controlled by multi-allele system in a single genetic locus, the S locus, and it is elucidated that S-glycoproteins are S gene products. In this experiments, we examined the genetic mode(pollen tube behavior and segregation of S-glycoprotein), characteristic of S-glycoproteins and DNA constitution within nuclear genome on S gene family that unexplained by single locus model, and investigated the segregation pattern of S-glycoproteins in bred F1 generation. By diallel cross among the 15 plants within one family the existence of three types of homozygotes and three types of heterozygotes were observed, and segregation of S-allele could not explained by single locus model. From the results of IEF-immunoblot analysis for non-segregated individual plant, the segregation pattern of S specific bands was corresponded with results of diallel cross except with one case(SaSa genotype). The molecular weight of 6 different S-genotype varied in near by 50 kD, and each genotype expressed with 2 or 3 bands. Specific bands in SaSa, SbSb, ScSc has almost similar molecular weight between them. Southern analysis of genomic DNA probed with S-glycoprotein cDNA for 6 different genotypes revealed that there are clear difference in polymorphism, multiple bands of hybridization, when restriction enzymes of EcoR I were used. It could be assumed that there are several sequences related to the S-glycoprotein structural genes within their nuclear genome. Therefore, we suggested the possibilities that S-allele system could be controlled by multi-locus, that dominance-recessive interactions could be explained by modifier gene or supressor gene based on the results of abnormal segregation of S-glycoprotein in bred F1. The F2 analyses are progressing in now.

Currently, the wireless network environment of air node is constructed mainly of ground relay station. However, as the Korean Peninsula is composed of 70% mountainous region, there are multiple shadow zones. This is calling for effective measures to prevent aircraft from losing communication link during low-mid altitude missions. In this article we propose the utilization of Bezier Curve for estimation of aircraft flight path and control method for entering shadow zone. This method successfully estimated aircraft track, and analyzed the existence, disseminated the warning, and took measures to avoid the shadow zone before entering. This article, suggested after simulated experiments, proves that the method enables seamless communication during air operations.
The purpose of this study is to examine the variables which influence old widows' life satisfaction. The subjects were 318 old widows over sixty years old in Kwangju. The data were taken by questionaires and analyzed by frequency distribution, percentile, AHOVA, scheffes test and multiple regression. The major findings of this study were as follows: 1) The majority of old widows were low educated and 36.2% were poor in health. Their living aspect that they live together with their married child was 74.2%. Degree of participation in social activities was very low. 42% were satisfied or very satisfied with their pocket money. 76.4% had religions. 25.5% had no old friend. Solidarity with their children was generally good. In their economical status, 8.4% of living together with married children were low while 35.3% of living separately were. 60% thought that they were important person at home. 35.5% answered that they were satisfied with their living condition and 6% were very satisfied. 2) The variables which affect the old widows' life satisfaction were age(p<0.05), state of health(p<0.001), degree of pocket money(p<0.01), economical status(p<0.05), roles at home(p<0.01), solidarity among their relatives(p<0.001), solidarity with their children(p<0.001), status in home(p<0.001) participation in social activities(p<0.05) and existence of old friend(p<0.01). 3) The significant orders which affect the old widow's life satisfaction were satus in home first of all (β=0.26, p<0.001), objective solidarity with their children(β=0.21, p<0.001), subjuctive solidarity with their children(β=0.19, p<0.01), state of health (β=0.15, p<0.01) and economical status who living with married child (β=0.15, p<0.01).
