  • Gear design carried in former type determined a few variables like module, pressure angle, helix angle. After investigating repeatedly results obtained through stress analysis and making a determination an optimal shape, but its design process was not only complex but also difficult to get a precise profile curve from operating by hand. In this study, rotating shape of gear profile curves were generated automatically with standard spur gear, equivalent helical gear, shifted gear & pinion by using developed program which is Auto_LISP language supported in Auto-CAD. Output tooth profile by using CAE program is applied as Preprocessor for stress analysis in each contact points. This program which can be determined rapidly an optimal shape of gear will be successfully supported for Small & Medium companies designing and manufacturing gears by using Auto-CAD.

  • This paper presents the computer program to design the synchronous sequential logic circuit. The computer program uses the MASK method to get the circuit of optimal cost. The computer program takes as an input, the minimal reduced state transition table where each state has its internal code. As an output,the optimal design of synchronous sequential logic circuit is generated for each flipflop type of JK,T,D, and RS respectively. And these circuits for 4 flipflop types are evaluated and sorted in ascending order of their costs, so that the user can select the proper flipflop type and its circuit. Furthermore,the proposed computer program may be applied to state assignment with its facility of cost evaluation.

  • This paper reports on the development of the analysis program of the piston skirt system, PS-LAP. It is essential to verify the stability of the design and to improve the performance of the system. In order to do that efficiently, it is required that integrated and interactive simulation analysis program. PS-LAP is developed in the base of the object-oriented, capsulation, modulization, OLE(objected linking and embedding) and variational design theory. So it contain the expandability and flexibility of the structure. In addition to that, it is programed to make the convenient user interface by using the visualization programming. It can support the modification of the piston skirt shape, lubrication condition and so on. It is expected to reduce the money and effort for design the piston skirt system.

  • The multi type heat pump system may provide more energy savings and better environmental conditions than the single type heat pump system may do. In order to design a multi type heat pump system, it may be recommended to develop the system simulation program, which can predict the characteristics of the system such as unit capacities, power consumptions, and system COP's. In this study, the steady state simulation program of the multi type heat pump system was developed. The results from the simulation program were compared with those from the experimental tests which were performed in the environmental chamber, Cooling tests show 3.11% and 0.94% of error in capacity and COP, and heating tests show 3.30% and 1.90% of error in capacity and COP, respectively. Therefore, the steady state simulation program developed for this study can effectively be used for the design and the performance prediction of the multi type heat pump system.

  • Purpose: The purpose of this study was to develop and apply a motivation-strengthening obesity management program for obese subjects with visual impairment and evaluate its effects. Methods: The program development and evaluation periods were from March to August 2018. The study design was an experimental study of non-equality, control repeat design. 25 subjects in the experimental group participated in the 12-week obesity management program and the 26 people in the control group did not. Results: The motivation-strengthening obesity management program included stretching exercises for 30 minutes in the morning five times a week. In addition, counseling, education, and group discussions were continued once a week for motivational strengthening. Special custom exercises for blind patients were also completed once a week simultaneously. Both of these activities were continued for 50 minutes a week for a total of 12 weeks. Measurements were recorded periodically to identify the sustained effects of the program. The obese subjects with visual impairment improved their knowledge of obesity, perceived disability, self-efficacy of exercise, and quality of life related to obesity through the motivational obesity management program. Waist circumference, systolic blood pressure, diastolic blood pressure, and fasting blood sugar were also improved in obese subjects. Conclusion: The study findings indicate that this program could be an active intervention for the control of weight gain in participants with visual impairment. Therefore, the motivation-strengthening program based on the ADDIE (Analysis, Design, Development, Implementation& Evaluation) model could be an effective strategy for better health outcomes of obese subjects with visual impairment.

  • Purpose: This study is to evaluate the effects of drug abuse prevention program for elementary school students. Method: The design of this study is nonequivalent control group pretest-posttest design. The subjects of experimental group were 27 students and the subjects of control group were 25 students in fifth grade of elementary school in C City, Gyeongsangbuk-do. The experimental group had Drug Abuse Prevention Program, which was two days per week program, for 5 weeks. And post-test was carried out in the same way as the pre-test. Data analysis was done using frequency, percentage, mean, standard deviation, Chi-square test, t-test, Paired Samples t-test using with SPSS WIN 11.0. Result: the experimental group, to which drug abuse prevention program was given, was improved in knowledge of drug and unacceptable attitude of drug compared to the control group, but there were no significant differences of self-esteem and assertiveness between two groups. Conclusion: The drug abuse prevention program was effective to increase knowledge and attitude of drug in elementary school students.

Method: The research design was a nonequivalent control group pretest-posttest design. There were 34 subjects in the experimental group and 34 in control group among 68 preschoolers in a nursery in the city of G. The experimental group received an 12 weeks psychomotorik. The out come variables were measured before and after the program. Collected data were analyzed by Fisher's exact test, t-test, $X^2$. test, repeated measures ANOVA & ANCOVA using the SPSS 15.0 program. Result: After psychomotorik program, self concept, sociability were increased and aggression decreased in the experimental group. Conclusion: Psychomotorik program was effective in increasing self concept and sociability and decreasing aggression. The program should be effective in psychological development of preshoolers.

  • In this paper, a design method of the simulation program for HILS(Hardware-In-the-Loop Simulation) system is proposed. The present method consists of definition of requirements for HILS, development of specifications, and implementation of the program to satisfy the specifications. In the implementation of the program, the application of hardware interface and the concept of structural modularization are proposed to satisfy the specifications. The concepts of CSCI(Computer Software Configuration Item) and encapsulation are used for structural modularization. The proposed method was practically applied to the development of the simulation program for the efficient operation in HILS of an anti-ship missile system.
