Traditionally, sib-pair linkage analysis with repeated measures has employed linear mixed models, but it suffers from the lack of power to find genetic marker loci associated with a phenotype of interest. In this paper, we use a gamma mixed model to improve sib-pair linkage analysis and compare it with a linear mixed model in terms of power and Type I error. We illustrate that the use of gamma mixed model can achieve higher power than linear mixed model with Genetic Analysis Workshop 13 data.

Purpose: This study is a descriptive and secondary analytical study that uses panel data to identify the factors of medication adherence to improve life care of hypertensive patients. Methods: The subjects of this study were 2,484 patients who were taking medication after hypertension using Korea Medical Panel 2015 data (β-version 1.0). Data analysis was performed using Chi-Square, Scheffe's test, and logistic regression using SPSS/win 22.0. Results: The level of medication adherence in patients with hypertension was 94.2%. The factors of medication adherence were gender and age in Model I of demographic factors, and the presence of disability, smoking, and drinking in Model II. Model III, which added drug use factors, was identified as drinking, drug duration, side effects, drug satisfaction, and payment of drug costs. Conclusion: In order to improve life care for hypertension patients, education and interventions on the importance of take medication and side effects of medications and how to take them will be needed in the early stages of diagnosis.

Purpose: This study is a descriptive and secondary analytical study that uses panel data to analysis of unmet healthcare needs and risk factors for improving life care of osteoporosis patients. Methods: The subjects of this study were 941 patients who were diagnosed with osteoporosis using Korea Medical Panel 2015 data(β-version 1.0). Data analysis was performed using Chi-Square and logistic regression using SPSS/win 22.0. Results: The unmet healthcare needs of osteoporosis patients were 22.6%. The factors of unmet healthcare needs were education level and age in Model I of demographic factors, and eating problems, memory problems, activity limitation, and disability in Model II. In Model III, which added socio-psychological factors, eating problems, memory problems, Total family income, and pain/Discomfort were identified. Conclusion: Based on the results of this study, it should be considered in the planning of medical policies to improve the life care of osteoporosis patients, and it is necessary to improve access to medical services and to prevent and mediate realistically to reduce unmet healthcare needs.

In this paper, I survey the field which students use ICT and propose a teaching and learning model to improve students' ability in using ICT. Also, I apply it and prove its' effect. Because Problem Based Learning treats ill-structured problem which reflects actuality, Students can pick up the actual knowledge and become verse in general principle or concept which can transmit resemble problem or situation. Therefore, I hope a teaching and learning model which I propose in this paper has an effect to improve students' ability in using ICT.

In this paper, we first construct a mathematical model for tagSNP selection based on LD measure $r^2$, then aiming at this kind of model, we develop an efficient algorithm, which is called approximate greedy algorithm. This algorithm is able to make up the disadvantage of the greedy algorithm for tagSNP selection. The key improvement of our approximate algorithm over greedy algorithm lies in that it adds local replacement(or local search) into the greedy search, tagSNP is replaced with the other SNP having greater similarity degree with it, and the local replacement is performed several times for a tagSNP so that it can improve the tagSNP set of the local precinct, thereby improve tagSNP set of whole precinct. The computational results prove that our approximate greedy algorithm can always find more efficient solutions than greedy algorithm, and improve the tagSNP set of whole precinct indeed.

The purpose of this study is to develop the lesson model for high school students to improve their abilities as consumer. In the method of the research, the contents on consumer education of the 8 kinds of Home Economics textbooks are reconstructed into the areas of decision-making, financing, reasonable purchasing, and consumer citizenship. The consumer’s ability to be developed in the areas of decision-making, financing, reasonable purchasing, and consumer citizenship is set up as follows： 1) The establishment of the sound consumer morality and values, the ability of independent decision-making, the critical ability, and the problem-solving ability. 2) The ability of research on social, cultural and economic values, and the ability to estimate one’s own short-term and long-term life plan. 3) The ability of reasonable purchase. 4) The ability to participate in a consumer movement, and the ability to take good care of environment. Subsequently, 9 lesson models for the student to improve the consumer’ability are developed.

This paper deals with the conductor bar design to improve starting stability of line start synchronous reluctance motor(LSSynRM). As design variables, the number and the shape of conductor bars of rotor are chosen. The starting characteristics are calculated by finite element method(FEM) and the conductor bars are designed to improve the starting torque according to the initial starting rotor position. Finally, the starting characteristic of the designed model are compared with that of the initial model.

The M&R(Maintenance & Repair) budgeting system for domestic military facilities based incremental budgeting model has caused many problems due to the difference between M&R requirement and budget, so military facility become early deterioration. this study proposes the application method of foreign M&R budgeting model for domestic military facility to improve current M&R budgeting system. In order to investigate the current status and problem of M&R budgeting system, this study reviewed various literature related characteristics and types of the foreign M&R budgeting model. The interview was performed for domestic military facility official. The model would greatly improve the current M&R budgeting process for the domestic military facilities.
