It is necessary a simple helicopter design and performance analysis program for a stage of helicopter conceptual design. To meet that needs, we have developed a program which is simply used to estimate helicopter configuration and performance. The program developed by this study is composed of Requirement, Mission profile Analysis, Size, Aerodynamic, Trim, Propulsion, Weight, and Performance modules, and each modules carry out operations for a given flight condition. In this study, we validate this analysis program in 9,500 1bs and 22,000 1bs helicopters and estimate design configuration and performance of 16,000 1b helicopter. And We can use this program to optimization process for Helicopter MDO framework.

The purpose of this study was to synthesize the results of studies on the effects of multi-cultural education program for Korean children. Using the author's own selection criteria, 17 studies were finally selected and 31 effect sizes were calculated from these studies and used for meta analysis. The overall effect size for all studies on the random effect model was .802, and it was positive and high. Given the heterogeneity among the effect size, subgroup analysis was conducted. According to the analysis, effect sizes significantly differed depending on program goal, concerned multi-cultural higher than others. Result also showed that the high scored effect sizes were the general family, pre-school age children group, and the program were 11-20 children group in size, and 11~20 times in frequency of education.

Purpose: This study explored the impact of using a music and horticultural therapy program on depression among rural seniors living in Yeongam-gun and conducted a comparative analysis before and after the program to present basic data helpful for an integrated mental health promotion program tailored to rural areas. Research methodology: The analysis subjects of this study were users of the rural residential program of 'Our Village Day Care Center' in Yeongam-gun in 2023, with a total of 20 people, 10 seniors for each program. The research analysis used SPSS to determine the effect on participation and depression before and after the program was implemented. Results: As a result of the analysis, depression levels decreased after completion of the horticultural therapy program and music therapy program, and this was statistically significant. Conclusion: Three implications are presented based on the following research results. First, the need for programs that can improve not only the physical health but also the mental health of elderly people living in rural areas is suggested. Second, the need for programs that link cultural programs such as music and gardening activities with welfare programs is suggested. Third, the need for follow-up management and verification of periodic mental health checkups for rural elderly is suggested.

This paper presents development of a Finite Element Analysis program. The program was developed on the based of second-dimensional plane strain rigid plasticity finite element analysis and an implicit program is coded. The program was tested by being applied to the axisymetric hydrostatic bulge forming processes using the circle dies. By the Finite Element Analysis at the fluid in chamber and at the blank material, we could know that the hydrostatic bulge forming processes can be influenced of material, the diameter of product and the forming velocity The developed Finite Element Analysis program was approved by the analysis results about forming variables.

This study was to analyze the effects of the career education program for students with disabilities. The analysis was performed based on two research questions. First, the total effect size on the career program for students with disabilities was considered. Second, the difference of the effect size between the sub-groups regarding dependency variables, types of disabilities, types of schools, number of people, and number of sessions was also included for analysis. For this, the author reviewed a database and analyzed 12 previous studies, presented in five master thesis and seven Korean journals from 2005 to 2015 based on the author's selection criteria. Subsequently, 27 effect size was found. The publication bias was analyzed by Rosenthal's fail-safe N. The overall effect size for all studies on the random effect model was 1.717, which was positive and high in value. Given the heterogeneity among the effect size, the subgroup analysis was conducted, and indicated that the effect size was significantly high when the purpose of the program was related to the student's self-decision ability. The results demonstrated that the programs were specified for students with intellectual disabilities, when the schools were elementary, when the number of students in a group was 1-10, and when program sessions lasted more than 21 times, the effect size was high. Implication for the future research and program implication were discussed on these findings.

The purpose of this study is to establish a purchasing cost reduction program for the management practical use. The research method of this study is a bibliographical search of the materials available in the library at Keimyung University and the writer's private study, and the case analysis. The body of this study is divided into three sections. The first section deals with the purchasing management systems in terms of the nature and characters of purchasing management and purchasing cost in total management system. The second section includes purchasing cost reduction program through value analysis technique and the third section covers summary and the following conclusions : 1) Top management should be aware of the important position of purchasing activities from the cost point of view, and they should be aware that a good purchasing cost reduction program could be established through value analysis technique. 2) For such a purchasing cost reduction program to be carried out. effectively the management should support and back up the program. 3) There should be a training program to educate and develop the personnel who can manage and operate the purchasing cost reduction program through valuean analysis technique. 4) And cooperative system should be established in management and operative organization system from the total management systems, view for the effective use of the program.

As an application of GPS is increased by world geodetic system introduction gradually, in this time, It is increased necessary of GPS baseline analysis program development. In this study, I developed a baseline analysis program by L1/L2 carrier. And I compared a baseline analysis result with a commercial program. I showed precision of approximately ${\pm}$1cm in a baseline length in case of Narrow lane as a result that a baseline analysised a developed program.

This study analyzed the learning components of the web-based adaptive math learning programs in order to develop adaptive math learning program using artificial intelligence. The components of the web-based adaptive math learning program set for analysis are classified into learning process presentation, concept learning, problem presentation, problem solving process, and learning result processing then analyzed three programs. As a result of analysis, the typical characteristic of components is that it uses a method of repeatedly presenting the same type of problem in order to learn one concept.

A computer program for matrix structural analysis by object-oriented programming technique using $C^{++}$ language has been developed. Object, class, method and inheritance which are used in object-oriented programming are illustrated using a graphical representation. The matrix operations and the structural analysis by matrix displacement method were satisfactorily performed by the proposed program. Numerical tests demonstrate that this proposed program can be widely used for the matrix structural analysis for personal computers.s.

In this study, an in-house program to predict steady state operation of micro gas turbines is constructed using MATLAB. The program consists of two parts: design and off-design simulations. The program is fully modular in its structure, and performance of each component (compressor, combustor, turbine, recuperative heat exchanger and pipe elements) is calculated in a separate calculation module using mass and energy balances as well as models for off-design characteristics. The off-design modules of compressor and turbine use performance maps, which are program inputs. The off-design operation of a micro gas turbine under development was predicted by the program. The prediction results were compared with those by commercial software, and the validity of the in-house program was confirmed.
