  • Axial-flow compressor is one of the most important parts of gas turbine units with axial turbine and combustor. Therefore, precise prediction of performance is very important for development of new compressor or modification of existing one. Meanline analysis is a simple, fast and powerful method for performance prediction of axial-flow compressors with different geometries. So, Meanline analysis is frequently used in preliminary design stage and performance analysis for given geometry data. Much correlations for meanline analysis have been developed theoretically and experimentally for estimating various types of losses and flow deviation angle for long time. In present study, meanline analysis program was developed to estimate compressor losses, incidence angles, deviation angles, stall and surge conditions with many correlations. Performance prediction of one stage axial compressors is conducted with this meanline analysis program. The comparison between experimental and numerical results show a good agreement. This meanline analysis program can be used for various types of single stage axial-flow compressors with different geometries, as well as multistage axial-flow compressors.

  • The purpose of this study was to develope a computer program to help with gross diagnosis of protein-energy balance and feeding management practice and with the prediction about the risk possibility of productive disease such as reproductive and metabolic disorders by evaluating fat, protein, and milk urea nitrogen (MUN) from individual cow milk in dairy herd Somatic cell counts also represent the condition of udder health. The principal flow charts of this program was to check on herd management, sampling the composite milk, analysis the milk composition, conversion of data from milking equipment to program, input and analysis of data in program, and report. This program is compatible with window 95/98 system. The major analytical elements of this program were presented as; the profile of herd lactation curve analysis of the test-day milk production level, the distribution of somatic cell count, the fat to protein ratio to evaluate body energy balance, and the interpretation of dietary protein-energy balance by milk protein and MUN contents for individual cows. This program using milk fat, protein, MUN, and somatic cell counts will serve as a monitoring tool for the protein-energy balance and the feeding management practice, and for distribution of mastitis in individual cows. It will also be used to manage the nutritional and reproductive disorders and mastitis at the farm level.

  • Purpose: This study was conducted to develop and evaluate a Web-based program for the maternal role of primiparas who use the internet. Method: The study process was a systems requirements analysis, design and development of a program, program testing by experts, program implementation, and program evaluation by users. A nonequivalent control group non-synchronized design was used. The data was collected from October 5th, 2002 to February 24th, 2003. Result: 1. Based on inquiries into mothers' needs, a Web-based support program was developed. The program was then modified from feedback received from experts. 2. In a sub-scale analysis of mothers' perception of a baby, amenability and persistence was significantly higher in the intervention group. The differences in the mean score of maternal self-confidence and maternal satisfaction were significant. 3. Cyber counseling was done for a total of 73 cases and the most frequent problems for counseling were feeding and nutrition (28.8%), followed by baby care, and health problems. Conclusion: It was proven that a Web-based support program provided appropriate support to primiparas and was effective in promoting their maternal role. Therefore, this study suggests that a Web-based support program for primiparas can become a powerful nursing intervention on virtually all mother and infant health concerns.

  • Objectives: This study aimed to develop a smoking cessation education program and to provide basic data for evaluating program for university students majoring in health sciences. Methods: The education program was developed based on the instructional system design model(ADDIE), that was based on literature review, brainstorming, and interviews of related experts. Education program was implemented for 2 sessions of 3 hours to the 82 university students majoring in health science. Knowledge, competency, and self-efficacy for performance of smoking cessation were analyzed. One group pre- & post-test design was used for evaluation of this program. Results: In the analysis stage, a total of 5 duties, 16 tasks, and 55 task elements were derived. In the design and development stage, based on job analysis, education program contents were composed of understanding tobacco, planning and implementation of smoking cessation program, smoking cessation counseling and drug treatment. After this education program, students achieved remarkable improvement in increasing knowledge, competency, and self-efficacy for smoking cessation counselling and program. Conclusions: It is needed to be included the smoking cessation education in department related to health science regular course.

  • The purpose of this study is to develop a competency strengthen program with the aim of training designers who respond to changing national policies in the era of artificial intelligence. To this end, this study was conducted through a total of five steps. First, through literature research and analysis of prior research and literature related to the role of training designers and HRD managers was investigated and analyzed, and based on related prior research, theoretical and academic grounds for training designer competency modeling were prepared. In the second stage, a draft training program was developed to strengthen the competency of training designers based on the needs analysis of stakeholders and advice from education experts. In the third stage, a pilot program was conducted based on the draft training program. In step 4, the effectiveness verification was confuted and the deficiencies of the training program were derived from the pilot program. Finally, the final draft of the training program for strengthening the competency of training designers in the era of artificial intelligence was developed. The final training program consisted of 10 modules and was designed to run for three days. The details of specific training program are presented in the article.

  • A BEM program is developed for the performance analysis of axisymmetric mufflers. In the program the sub-region method is used to deal with singularity or inner boundary. The program is applied to typical axisymmjetric mufflers such as simple expansion, extended tube, perforated tube and absorptive expansion sufflers. The transmission losses of the mufflers are calculated by the program and compared with experiments. It is found that the prediction is in a good agreement with measurement, except for the absorptive muffler with parallel lining.

  • A general purpose program, TURBO-3D, for the analysis of 3-D fluid flow in complex geometry has been developed, which employs a standard $k-\varepsilon$ turbulence model and a general nonorthogonal grid system. For the purpose of verification of the program and testing the applicability, turbulent flows in an S-shaped diffuser and turbulent flows over an backward facing step are solved and compared with the earlier results. Comparison with the results by the STAR-CD program has been also made for the same flow configuration and grid structure. The agreements are excellent and hence the program has been verified. Since the present program is applicable only on limited flow phenomena and lacks the pre-and post processor, further improvements toward these directions are being made.
