Purpose: This study was done to identify the effectiveness of a web based learning program on self efficacy, knowledge, and competence in measurement of blood pressure in college nursing students. Method: This study was an experimental research study. Data were collected from April 20 to June 1. 2011. The participants were 68 first year nursing students (experimental group 37, control group 31). The collected data were analyzed with the PASW 18.0 program, using ${\chi}^2$-test, t-test, and Cronbach's ${\alpha}$. Results: The mean score for self efficacy in blood pressure measurement in the experimental group was 61.9 and in the control group 60.7. This result was statistically significant (t=3.301, p=.002). The mean score for knowledge of blood pressure measurement in the experimental group was 11.5 and in the control group 10.8. This result was statistically significant (t=2.910, p=.005). But effectiveness of competence in blood pressure measurement was not significant. Conclusion: The study results show that the web based learning program was effective for self efficacy and knowledge in blood pressure measurement but not for competence indicating.-a need to develop strategies to improve competence in blood presessure measurement for these students.

폐쇄생태계는 연구자가 다양한 환경 요인을 조사 목적에 맞게 조절하여 생태계의 변화를 모니터링 할 수 있는 장점이 있어 영양역학적 연구와 같은 기초학문 연구뿐만 아니라 독성실험 및 환경오염에 대한 생태계의 변화 실험 등 응용분야에서도 활용도가 높다. 특히 현장에 해양 폐쇄생태계를 설치하기 때문에 실험실에서의 실험보다 자연에 가까운 조건에서 실험을 할 수 있어, 신뢰성 있는 실험 결과를 얻을 수 있다는 장점이 있다. 그러나 국내에서 폐쇄생태계를 활용하여 해양생태계를 연구한 결과는 극히 적다. 이 논문에서는 기존에 국내외에서 제작되어 실험에 사용되었던 폐쇄생태계와 이를 활용한 연구과제를 소개하고, 향후 폐쇄생태계를 활용하여 연구할 수 있는 연구과제를 제안하였다.

The purpose of this study was to develop on east-west nursing intervention program. This study was conducted to identify the effectiveness of using facial meridian points for massage nursing intervention on the recovery of facial paralysis for 46 patients (22 for experimental group). All had suffered from strokes, and were also admitted to the division of oriental medicine in K University Hospital. Method: Data was collected from February 1st to December 31st of 2000. This study used a quasi experimental, non-equivalent control group pre-test and post-test design. The recovery of facial paralysis was measured by the difference between left and right facial length, observation and self report on a seven point scale, and facial discomfort by a facial scale after 6-7 facial massages in a two week period. Data was analyzed using the SPSS package program with x2 and t test. Result: The result of this study are as follows; The experimental group who received the facial meridian massage showed higher scores in recovery of facial paralysis (t=2.72, p=.009), and a smaller difference between left and right facial strength than those in control group (t=2.26, p= .29). The discomfort of the facial area in the experimental and control group showed no significant differences. Conclusion: These findings indicate that a facial meridian points massage could be an effective nursing intervention to the recovery of facial paralysis. This study contributes in developing an east-west nursing intervention with the oriental meridian theory and western massage therapy.

Automated material handling system is being used as a method to reduce manufacturing cost in the semiconductor and flat panel displays (FPDs) manufacturing process. Those are considering switch-over from the traditional cassette system to single-substrate transfer system to reduce raw materials of stocks in the processing line. In the present study, the wafer transportation speed has been evaluated by numerical and experimental method for three propulsion nozzle array (face, front, rear) in an air levitation system. Test facility for 300 mm wafer was equipped with two control tracks and a transfer track of 1,500mm length. The diameter of propulsion nozzle is 0.8mm and air velocity of wafer propulsion is $50\sim150m/s$. We found that the experimental results of the wafer transportation speed were well agreed with the numerical ones. Namely, the predicted values of the maximum wafer transportation speed are higher than those values of experimental data by 16% and the numerical result of the mean wafer transportation speed is higher than the experimental result within 20%.

The purpose of this study is development of learning coaching program that is grafted onto advantage of Self-directed learning and coaching intended for Youth-After-School-Academy children and analysis the effect on self-efficacy and Self-directed learning ability from this program. The program of this study is developed on the base of Seels & Richey's 'ADDIE Model'. In order to verify the effect of this study, two times tests were carried out on 14 persons of the experimental group and the control group respectively, before and after the program was performed. The MANCOVA & ANCOVA was done on the difference between the post-test results of the experimental group and the control group. Findings of this study might be summarized as follows: First, the post-test result in the experimental group on self-efficacy was meaningfully higher than in the control group. Second, on Self-directed learning ability the result in the experimental group was also higher than in the control group. Therefore, learning coaching program impacted on self-efficacy and Self-directed learning ability of Youth-After-School-Academy children. This program that aim to discover the potential on learning, expect to be effective for children education of today when pursue Self-directed learning ability and creativity.

The purpose of this study is to investigate how free inquiry activities affects the scientific process skills and scientific attitudes of 5th and 6th of elementary school students. For this study, 265 elementary students from 5th and 6th grade in Seoul were selected. In comparison group 130 students were implemented and to the experimental group 135 students who did not the free inquiry activities were implemented. The result of this study is as follows: First, curiosity was the most affective factor that motivate free inquiry activities and made them select their topics. Most of the students invested for the inquiry activity in less than 3 weeks. They had some help in every stages. Students became interested in free inquiry activities because they learned new facts and enjoyed doing experiments and they wanted to continue for the same reasons. Second, free inquiry activities had little effect on the basic science process skills of the experimental group, compared to the control group at the significant difference of p=0.05. Third, free inquiry activities had considerable effect on the integrative inquiry process skills of the experimental group, compared to the control group at the significant difference of p=0.05. Fourth, the result of the post-test of the experimental group showed that free inquiry activities had no effect on scientific attitudes at the significant difference of p=0.05. In conclusion, free inquiry activities will be much more effective in developing integrative inquiry process skills than in developing basic scientific process skills and scientific attitudes.

Background: The purpose of this study was to confirm whether surface FES was effective in the function of chronic stroke patients' affected shoulder and whether FES influenced their functional abilities in ADL, as well. Method: the subjects were inpatients at a general hospital in Gyeonggi-Do, Korea and had been diagnosed as a sub-luxation in their affected shoulder. They were 26 and were separated to an experimental group and a control group, in equal number. Both groups had gotten an exercise treatment for 6 weeks. The control group didn't get any FES as opposed to the experimental group. Result: in the experimental group there was no statistical significant difference in the vertical space and the joint space, even though the space was reduced. In the control group, there was no statistical significant difference, either. Moreover, each space of their shoulders was increased. In the range of motion of each group, there was no statistical significant difference. In functional independent ability, there was a significant difference in an experimental group. In contrast, there was no difference in a control group. Conclusion: this result suggests that FES should be effective in the sub-luxation of the patients' affected shoulder and the range of motion of their shoulders. On the other hand, compared to the previous items, FES was quite effective in the functional improvement.

This experimental study was carried out to estmate the effects of mixing dosage rate and blain on the compressive strength properties of antiwashout underwater concrete admixed with finely ground granulated blast furnace slag. The experimental parameters are slag contents(0, 20, 30, 40, 50, 60%). As a result the compressive strength have a high correlation with slag blended ratio. Thus, it is possible to calculate the modulus of modified age using compressive strength of antiwashout underwater concrete blended with slag.
