Purpose: The purpose of this study was to probe the effect of foot reflexology education program on nursing students with constipation, anxiety and depression. This study was a quasi-experimental study of pre-test and posttest design on non-equivalent control group. Method: The data of this study were collected from October 28, to December 14, 2002. The subjects consisted of 61 nursing students (experimental group: 31, control group: 30) with constipation, anxiety and depression. 31 out of them were devided into the experimental group and received foot reflexology education program that was authorized by the World Foot Reflexology Association and made to suit for the subjects by the author for 6weeks composed of 2 weeks theory and of 4 weeks practical skill on the program. The effect of the program was measured by Bowel Function Assessment Form for constipation, State Anxiety Inventory, and Beck Depression Inventory. Data were analyzed by t-test, $x^2$-test, Repeated measures ANOVA, Bonferroni multiple comparison using SAS/PC 8.12 program. Result: After all session of treatment, the score of bowel function assessment were significantly decreased in the experimental group compared to the control group. Outcomes of 6 and 7 weeks were significantly different from those of pre-experiment. After all session of treatment, anxiety states were significantly decreased in the experimental group compared to the control group. Outcomes of 7 weeks were significantly different from those of pre-experiment. After all session of treatment, depression states were significantly decreased in the experimental group compared to the control group. Outcomes of 6 and 7 weeks were significantly different from those of pre- experiment. Conclusion: The results are suggested that the foot reflexology education program might improve the bowel function, anxiety and depression for the nursing students with constipation, anxiety and depression.

Experimental conditions are set with environmental factors which can affect ship navigation. In FTS simulation, infinite simulation can be theoretically tested with no time constraint but the simulated result with the same experimental condition is repeated due to mathematical model. RTS simulation can give more resonable results but costs at lest 30 minutes for only experimental time. The mixture of two simulation methods using probability density function has been proposed: some of experimental conditions in which ship-handling is most difficult are selected with FTS and are tested in RTS. It has drawback that it does not consider the navigation route but aggregated track index. In this paper, anomaly detection approach is suggested to select some experimental conditions of FTS simulation which are most difficult in ship-handling during the navigation route. An empirical result has been shown.

This study, as one on the neck design of seamless knitwears, set out to make experimental clothes applying various knitting methods to the hem of round neck, seek the knitting methods of finishing touches on the ending part of round neck to enhance function and aesthetic appreciation through measuring tensile strength and assessing wearing sensation, and provide basic data that would be of practical help to developing the design of seamless knitwears and mass production in the national knit industry. The ending part of neck of the seamless knitwear is not only the last stage in making knitwear but also affects the function and appearance of the clothes. The investigator, thus made six different pieces of experimental clothes according to the finishing methods of knitting on the neck, then measured tensile strength and put them to the test by a group of experts for the assessment of wearing sensation. The results were analyzed based on variance analysis(ANOVA), and the items with similar results were put to the Duncan test for intergroup comparison. According to the analysis results of measuring tensile strength, Experimental Clothes B received the highest evaluation, Experimental Clothes E the lowest. Also Experimental Clothes B was ranked the highest in almost every evaluation criteria, whereas Experimental Clothes E was ranked the lowest in the assessment of wearing sensation.

A nonlinear FEM analysis of steel members under very-low-cycle loading has been performed in conjunction with experimental works. This analysis is an FEM tracing toward cracking of steel members under cyclic loads such as a strong earthquake. After verifying the procedure by comparing global hysteretic behaviors from the analytical and experimental results, the local stress-strain hysteresis at critical sections for large cyclic deformations was traced by the numerical analysis. Local strain history was discussed in relation to cracking. Based on the experimental and analytical results, a new approach to seismic safety assessment for steel members was proposed in this paper.

Purpose: The purpose of this study was to identify the effects of structured information provided on self care knowledge, self care performance, and functional status. Method: The data were collected using self care knowledge and performance assessment tool, and functional status assessment tool from both group hospitalized patients at D hospital in Busan. Results: There was a significant improvement(p=.032) in self care knowledge in experimental group compared to the control group. But there were not improvement in self care performance and functional status in experimental group compared to the control group. But comparing to pretest and posttest in experimental group, There were significant improvement in self care performance (p=.003) and functional status(p=.013). Conclusion: Structured information provided showed increased in the degree of knowledge, self care performance, and functional status. But the effect size of program which had been developed in this study was estimated small, so there is needed to modify this program and to research repeatedly.

Purpose: The purpose of this study was to evaluate the effects of clinical practice and simulation-based practice for obstetrical nursing in terms of self-efficacy, practice satisfaction, and practice stress. Methods: A non-equivalent control group post test design was used. The participants were 171 junior nursing students, 103 in the experimental group, and 68 in the control group. Simulation-based practice consisted of nursing assessment during labor, nursing assessment and intervention for normal and high risk mother, nursing education for mother and family during labor, and open lab. The experimental group participated in simulation-based practice for two days and the control group participated in clinical practice at delivery room for two weeks. Results: The experimental group showed higher level of self-efficacy (p= .043), practice satisfaction (p<.001) and practice stress (p=.003) compared to the control group. Conclusion: Simulation-based practice is an effective learning method for obstetrical nursing and can be used as the alternative for clinical practice. However, stress management strategies are needed for simulation-based practice.

The purpose of this study is to develop an experimental model for information needs assessment, which could be utilized to investigate the 'real' information needs of the user(or group). The focus was on the perspectives of users rather than those of system managers. In details, this study identifies the conceptual definition of the keyword 'information need', analyzes the limitation and problems the previously conducted needs assessments in this area, and finally, develops an experimental model based on the cognitive and affective variables which might influence both production and strength of information needs in the user(or group}. The model emphasizes four influencing variable, namely, individual, work-related, organizational(or institutional), and socio-cultural variables. Also discussed is the relationships among these variables.
