  • Novel method to calculate flux linkage for 3-D finite element analysis is proposed. It does not require any integral path if the current direction in a coil is known. The flux linkage can be calculated very easily using simple volume based integration. The current direction is calculated based on the recently developed technique by the authors. The novel method for flux linkage calculation is verified by applying to a very complicated deflection yoke coil. The simulation result is compared to the experimental one. From the simulation, it is shown that the proposed method is very accurate and effective to calculate the flux linkage of a coil.

  • Evidence of linkage is expressed as a decreasing trend of the squared trait difference of two siblings with increasing identical by descent scores. In contrast to successes in the application of a parametric approach of Haseman-Elston regression, notably low powers are demonstrated in the nonparametric linkage analysis methods for complex traits and diseases with sib-pairs data. We report that the Genehunter nonparametric linkage statistic is biased and furthermore the variance formula that they used is an inflated one, and this is one reason for a low performance. Thus, we propose bias-corrected nonparametric linkage statistics. Simulation studies comparing our proposed nonparametric test statistics versus the existing test statistics suggest that the bias-corrected new nonparametric test statistics are more powerful and attains efficiencies close to that of Haseman-Elston regression.

  • The Purpose of this study is to suggest the necessity of linking and coordinating Cultural Tourism Festivals among local governments and to propose a plan for maximizing the effects of these festivals. The 'World Ceramic Exposition 2001 Korea' which took place from August 10th to October 28th was selected as a case study for the linkage plan of Cultural Tourism Festivals among local governments. Data were collected from a random sampling of visitors to 'World Ceramic Exposition 2001 Korea' from 24 to 28 October, 2001. 369 samples from a total 375 respondents were used for the final analysis. The contents of the questionnaire consisted of the cognition and satisfaction about the effects of the festival linkage among local governments and the preference of festival linkage types. The results of the analysis showed that not only festival staff but also visitors recognized the necessity of linking festivals among regions. Both visitors and festival staff had a positive attitude about the effects of the linked festival. In addition, they highly rated the 'World Ceramic Exposition 2001 Korea' as a successful festival. Visitors were satisfied with the festival. Furthermore, the number of visitors was more than staff expected. The organizing committee and staff considered the 'World Ceramic Exposition 2001 Korea' as a successful festival. The successful evaluation of the 'World Ceramic Exposition 2001 Korea' was related to the successful linkage of the festival. This study originated in the increased necessity of linking cultural Tourism Festivals among local governments. Since it is a transcendental study, it is not only significant but also limited. However, in the near future, more varied case studies about the linkages of Festivals will be conducted and these will generalize the results of this study and test the effectiveness of the linkage plans through positive analysis. For the effective linking of festivals among regions, it is necessary to study the definition of factors that affect visitors satisfaction, and determine which methods will improve visitors satisfaction.

  • This study established administrative districts of Myeon based on linkage analysis for Chungwa-myeon, Oksan-myeon, Naesan-myeon and Yanghwa-myeon which have the population of less than 2,000 among 15 Myeons in Buyeo-gun, Chungcheongnam-province. As the result of the analysis, it was analyzed that Chungwa-myeon was the most highly linked with Imcheon-myeon. Oksan-myeon had high linkage with Hongsan-myeon while Naesan-myeon had high linkage with Guryong-myeon. Lastly, it was analyzed that Yanghwa-myeon had high linkage with Chunghwa-myeon and Imcheon-myeon. It can be judged that this result comparatively agrees with the local history and policy of Buyeo-gun. Since the average area of a 'Myeon' is much larger than that of 'Dong', it will be difficult to provide administrative services if they are forced to be consolidated based only on population. Thus, it is necessary to establish standards which consider the population and area simultaneously.

  • This study was carried out to construct mapping population and to evaluate the methods involved, including polymorphic DNA marker system and appropriate statistical analysis. As an initial step to establish chicken genome mapping project, White Leghorn (WL) and Korean Ogol chicken (KOC) were used for generating backcross population. From 8 initial parents, total 280 backcross progenies were obtained and 40 were used for genotyping and linkage analysis. For development of novel polymorphic markers for KOC, Random Amplified Polymorphic DNA (RAPD) markers specific for this chicken line were generated. Also included in this study were six microsatellite markers from East Lansing map as reference loci. For segregation analysis, 15 RAPD markers and 6 microsatellites were used to genotype the backcross population. Among the RAPD markers that we developed, 2 pairs of markers were identified to be linked and another 4 RAPD markers showed linkage with microsatellites of known map. In summary, this study showed that our backcross population generated from the mating of KOC to WL serves as a valuable genetic resource for genotyping. Furthermore, RAPD markers are proved to be valuable in linkage mapping analysis.

  • Violence against women includes sexual violence, domestic violence, trafficking, etc. It is a serious problem that violates women's rights and basic freedom. In Korea, with the enactment of the laws on sexual violence and domestic violence in the 1990s, counseling centers and protective facilities for the victims began to be established and have been rapidly increasing in number recently. The purpose of this research was to investigate the current status of the counseling services with a focus on their linkage function. 78 out of 109 counselors working in the counseling centers for sexual and domestic violence throughout Korea responded to a mail survey. The questions included the general characteristics of the centers and the counselors, the structural, relationship and process dimensions of linkage function, and the subjective and objective aspects of the degree of linkage. The findings of the analysis highlighted the following problems. First, the counseling centers played limited role in serving the victims of violence due to lack of resources in the service network. Second, the linkage of services existed on a relatively small scale which was mostly based upon informal and unstructured relationship. Third, according to the multivariate analysis, the existence of potential partner agencies, the effort of the line staff to initiate the linkage relationship and mutual cooperation between agencies determined the degree of linkage among services. These findings suggest implications for establishing a more effective system to protect the victims of violence.

  • Purpose: This study was to analyze the factors that affect the service relationship of long term care workers for the elderly and to provide basic resource for the successful connection of long term care services. Methods: 259 subjects who were engaged in long term care units completed a self-administered questionnaire that measured the extent of service linkage among one another. The Cronbach's ${\alpha}$ score determined the internal consistency of the acquired data and the discriminated validity was estimated by Pearson's correlation coefficient. Multiple regression analysis was conducted to investigate the influence of the known factors on the service linkage. Results: Acceptance and participation negatively influenced on the service linkage. Reliance, comprehension, recognition on service, and frequent contact with others positively activated the service linkage of long term care workers. Conclusion: The establishments of systemic training courses providing education that emphasizes reliability and recognizes other services, including work environment to contact easily are needed to improve the service-linkage of long-term care workers for the elderly.

  • Autosomal Dominant Polycystic Kidney Disease (ADPKD) is one of the most common inherited renal disorders in the world. Mutations in PKD1 located on chromosome 16p13.3 are responsible for 85% of all the ADPKD patients whereas mutations in PKD2 on chromosome 4q21-23 are responsible for the rest of the cases. Genetic heterogeneity and the problems of mutation detection in PKD1 suggest that linkage analysis is an important approach to study the genetics of ADPKD. To evaluate the availability of six (CA)n microsatellite markers for the linkage analysis of ADPKD in the Korean population, we examined the allele frequencies and heterozygosities of the markers. With the exception of KG8, five markers were highly informative, with PIC values over 0.5, but the PIC value of KG8 marker was less informative than other five markers because of the low number of alleles. Therefore, this study will be useful in linkage analysis for ADPKD families in the Korean population.

  • It is very important to correctly set control surface linkage. But a lot of bad setting case has been seen in especially remote controled airplanes and middle size UAVs. In this paper, a three dimensional linkage from control surface to deflection sensor was analyzed kinematically and a position analysis was simulated using algebraic algorithm in terms of nonlinear error of deflection angle. Three correct settings of the linkage came out of this research. One is two-dimensional motion, another is link ratio of 1 and the other is that effective lever of the control surface should be perpendicular to a pushrod in their neutral position.
