This study describes the development of nursing education program on web-based instruction for Nursing Management Practice of nursing school. The program has been developed based on five steps of the teaching-learning design model developed by Chung, In-Sung which is widely used in Web-Based Instruction(WBI). The objective of this study was to develop nursing education program on WEI and to evaluate its effectiveness. The subjects consisted of twenty-four senior nursing students taking the Nursing Management Practice course. Two sets of questionnaires were used for this study. They were asked to evaluate the program in terms of appropriateness of the teaching strategy, precision of the contents, easiness of use, easiness of approaching system, interface design, system management, enhancement of communication, and effectiveness of learning. The program was developed in five steps, analysis of the student, design of the contents, production of the system, implementation of the system, and evaluation of the effectiveness. It is concluded that this program was very useful in increasing the effectiveness of learning and motivation in the students. In addition to this, the web-based learning system would be one of the best qualified educational method for nursing students. Therefore, I would suggest that it can be used for other nursing courses which is available on the Web.

The purpose of this study is to evaluate the effects of Qigong gymnastics exercise program on the physiopsychological parameter in essential hypertension. The design of the research was a one group pretest-posttest design. A total of 20 pateints with hypertension who were from forty to sixty-five years old participated in the study. The Qigong gymnastics program was carried out twice a week for thirty minutes or forty minutes for six weeks from 22, Sep. to 31, Oct. in 1997. In order to evaluate the effect of the Qigong gymnastics program physiological parameter (blood pressure, pulse rate, FVC, FEV1, Epinephrine, Norepinephrine, Cortisol) and psychological parameter(self-efficacy, Life satisfaction) were measured before and after the exercise program. Collected data was analyzed by the paired t-test with SAS package. The result are as follows : 1) There were significant decrease in systolic blood pressure and diastolic blood pressure, but there was no significant change in pulse rate. 2) There were no significant difference in FVC and FEV1 3) There were significant decrease in epinephrine, norepinephrine and cortisol. 4) There were significant improved in general self-efficacy and life satisfaction. 5) The effect of Qigong gymnastics program by measurement time on blood pressure and pulse rate were as follows : In a systolic blood pressure was gradually significant decreased from 1 week to 6 weeks and diastolic blood pressure was significantly decreased after 4weeks. But there was no significant change in pulse rate. This results suggest that Qigong gymnastics are an appropriate nursing intervention for clients with hypertension. For further research is necessary to reevaluate the effect with a letter experimental design and longer period than 8 weeks for the Qigong gymnastics program.

A program to design a small capacity wind turbine blade is proposed in this study. The program is based on a matlab GUI environment and designed to perform blade design based on the blade element momentum theory. The program is different from other simulation tools available in a point that it can analyze the side-furling power regulation mechanism and also has an algorithm to find out optimal torque schedule above the rated wind speed region. The side-furling power regulation is used for small-capacity horizontal axis wind turbines because they cannot use active pitch control due to high cost which is commonly used for large-capacity wind turbine. Also, the torque schedule above the rated wind speed region should be different from that of the large capacity wind turbines because active pitching is not used. The program developed in this study was validated with the results with FAST which is the only program that can analyze the performance of side-furled wind turbines. For the validation a commercial 10 kW wind turbine data which is available in the literature was used. From the validation, it was found that the performance prediction from the proposed simple program is close to those from FAST. It was also found that the optimal torque scheduling from the proposed program was found to increase the turbine power substantially. Further experimental validation will be performed as a future work.

Purpose: The study aimed to design and develop an automated personalized self-care (APSC) program for patients with type 2 diabetes mellitus. The secondary aim was to present a clinical protocol as a mixed-method research to test the program effects. Methods: The APSC program was developed in the order of analysis, design, implementation, and evaluation according to the software development life cycle, and was guided by the self-regulatory theory. The content validity, heuristics, and usability of the program were verified by experts and patients with type 2 diabetes mellitus. Results: The APSC program was developed based on goal setting, education, monitoring, and feedback components corresponding to the phases of forethought, performance/volitional control, and self-reflection of self-regulatory theory. Using the mobile application, the participants are able to learn from educational materials, monitor their health behaviors, receive weekly-automated personalized goals and feedback messages, and use an automated conversation system to solve the problems related to self-care. The ongoing two-year study utilizes a mixed method design, with 180 patients having type 2 diabetes mellitus randomized to receive either the intervention or usual care. The participants will be reviewed for self-care self-efficacy, health behaviors, and health outcomes at 6, 12, 18, and 24 months. Participants in the intervention group will be interviewed about their experiences. Conclusion: The APSC program can serve as an effective tool for facilitating diabetes health behaviors by improving patients' self-care self-efficacy and self-regulation for self-care. However, the clinical effectiveness of this program requires further investigation.

This study aims to verify the effectiveness of the programming-based TPACK educational program developed by Kim and Lee (2019) in improving the TPACK of pre-service teachers. The treatment used ICT-based (control) and programming-based TPACK educational programs (first, second, third, and final cycle) developed through design-based research. TPACK test tools were implemented pre and post treatment, and the test results were analyzed using ANCOVA. Therefore, the TPACK of pre-service teachers who implemented the programming-based TPACK educational program was significantly higher compared to the ICT-based TPACK educational program. Furthermore, through this design-based research, the effect of the developed final educational program on the TPACK of pre-service teachers was particularly the most outstanding. Therefore, it can be concluded that the programming-based TPACK education program developed through design-based research is effective in improving the TPACK of pre-service teachers.

This study verified the effects that a programming-based TPACK education program, through design-based research on TPACK, had on pre-service teachers. The research subjects were pre-service teachers attending teacher training at a university in Korea, and 129 control groups and 126 experimental groups were recruited through lectures. The treatment used a TPACK educational program developed in a design-based study (Kim & Lee, 2019). A TPACK test tool developed by Park and Kang (2014) was used. The test results were analyzed via independent sample t-test and paired sample t-test. The results show that the programming-based TPACK education program (first cycle) was only effective in improving TPK and TPACK, but an effective educational program was developed to improve PCK, TCK, TK (second cycle), PK (third cycle), and CK (final cycle). This design-based research therefore confirmed the development of a programming-based TPACK education program that was effective for improving the TPACK of pre-service teachers.

The purpose of this study is to present types of design concept based on the specificity of landscape design, and to derive a theoretical framework for the landscape design concepts by analyzing the design concepts appearing in urban park design competitions. Through literature review, five types of landscape design concepts were categorized into value and vision, analysis and interpretation, form and structure, program and element, and process and operation. Using this framework, the design concepts shown in 96 works submitted to 18 domestic and overseas urban park design competitions were analyzed. The results of the analysis are summarized as follows. First, due to the complexity of contemporary urban parks, design concepts are presented as mixtures of main concepts and secondary concepts in multiple layers. Second, it was identified that design concepts of 'form and structure' were used the most in urban park designs, followed by the 'program and element' concepts. The 'value and vision' and 'analysis and interpretive' concepts are introduced as third and fourth. Third, the reason that the 'form and structure' concept is widely used as main and secondary concepts is judged to be because the form of a space, which is the key result of the design, has an important influence on the identity of the design. Fourth, the reason that the 'program and element' concept type is widely introduced is that urban park design has a stronger planning aspect to produce programs during the design process, compared with other design fields where programs are usually given in advance. Lastly, it is difficult to see that the properties of the site solely affect the type of design concept, because a design concept is the result of a complex and creative process in which a designer subjectively interprets the objective characteristics of the site and project, and given design guidelines can affect the type of design concept.

In recent years, the needs of consumers for personality and personalized clothing are increasing. Knitting machines, which produce clothing by the user at low cost, are a good way to meet consumer demand. However, the user is having difficulty in using the knitting machine pattern program, which is a software program, independently of the operation of the knitting machine. Therefore, this study conducted a literature review prior to the empirical research and evaluated the usability by selecting three kinds of frequently used knitting machine pattern programs as research subjects. Based on the nine usability evaluation principles derived from expert group discussions, the study found that the needs of users for nine evaluation principles: visibility, conciseness, operability, consistency, accuracy, flexibility, intuition, error recognition, and supplementary explanation (The purpose of this study is to identify the direction and alternatives of usability improvement for the interface of the knitting machine pattern program.

In case of constructing final closure in sea having big tide variation, the velocity in gap and the seepage velocity under the revet are faster because of inner and outer water level difference of the revet. Thus, the rubbles for final closure lose and the original ground is scoured by piping. There are several difficulties from the view of construction efficiency and safety. This study finds hydraulic phenomena in final closing construction area, develops a program for final closing simulation, minimizes the error during design and construction, and supports the engineering capacity for efficient and safe construction. The existing design method for final closure only considers the flow in gap, but the developed program considers the seepage in revet and flow in closure gap. This developed program chooses the suitable rock size for final closing design and establishes the proper method for final closing construction.
