A key comparison has been made between the air-kerma standards of the National Institute of Metrology (NIM), China, and other Asia Pacific Metrology Programme (APMP) members in the medium-energy X-ray. This paper reviews the primary standard Free-air ionization chamber correction factor experimental method and Monte Carlo simulation method in the NIM. The experimental method and the Monte Carlo simulation method are adopted to obtain the correction factor for the medium-energy X-ray primary standard free-air ionization chamber at 100 kV, 135 kV, 180 kV, 250 kV four CCRI reference qualities. The correction factor has already been submitted to the APMP as key comparison data and the results are in good agreement with those obtained in previous studies. This study shows that the experimental method and the EGSnrc simulation method are usually used in the measurement of the correction factor. In particular, the application of the simulation methods is more common.

The aim of this study is to clarify what influence has on elementary school children's environmental awareness in time of teaching environmental problems from an animistic viewpoint and from non-animistic viewpoint. For this purpose, this study carried out its research targeting 126 students in fourth grade at M elementary school located in U Metropolitan City. This study suggested the environmental problems by re-edifying the already suggested environmental problems from an animistic viewpoint to 62 students for two classes which were classified as an experimental group after sampling 10 cases of the representative environmental problems that might derive from the earth system, and conducted the class on 10 main topics relevant to the problematic situation of environment with an animistic viewpoint excluded targeting the remaining 64 students forming a comparison group. The results of this study were as follows: First, there appeared an ex-ante ex-post statistically significant difference in the awareness of environmental problems from the experimental group which received an environmental class from an animistic viewpoint. However, there didn't appear a statistically significant difference from the comparison group. This study interprets this result to mean that elementary students' awareness of environmental problems increase because they think about the environmental problems by associating them with a problem of life when the students receive the environmental class from an animistic viewpoint. Second, there appeared an ex-ante ex-post statistically significant difference in the awareness of environmental problems from the experimental group which received an environmental class from an animistic viewpoint. However, there didn't appear a statistically significant difference from the comparison group. Regarding this aspect, this study believes that the experimental group shows much higher willingness to environmental act in comparison with the comparison group because elementary school students think of inanimate objects as living things.

In this study, the researcher tried to find out the effect of using a computer interface in teaching speed concept in the elementary school. The 4th and 5th pupils were sampled for this study. The school is located in a sub-urban agricultural area in Korea. In the study, the subjects were divided into two groups: experimental and comparison group. From the pretest, two groups did not show any difference in the understanding of speed concept. The computer interface and the programs to operate the interface and data analysis were developed by researcher. The interface is a modular type and designed ready to connect to microcomputer. The test items were consisted of (1) comparison of speed, (2) change of motion, (3) acceleration, and (4) deceleration. As the result, the researcher found the following results: 1. In case of speed comparison, no significant difference was found between experimental and comparison group. 2. In case of change of motion, acceleration, and deceleration, the experimental groups showed higher achievement both in 4th grade and 5th grade. However, the 4th graders showed more learning than the 5th graders. In conclusion, this study showed that the use of computer interface seemed to be very effective in teaching and learning speed concept in elementary school.

Purpose: The purpose of this study was to analyze the effects of a cognitive-behavioral nursing intervention on anxiety and depression of patients with breast cancer undergoing radiotherapy. Methods: A nonequivalent control group design was used for the study. The research participants were patients with breast cancer (N=71; experimental group=35, comparison group=36) who received radiotherapy at P university hospital. The experimental group received a 6-week cognitivebehavioral nursing intervention (2 hr/week), which included nursing counseling, education about treatment choices for breast cancer and possible side effects and management strategies during radiotherapy, and rehabilitation exercise. Results: Following the intervention, the experimental group showed significantly lower levels of anxiety (Experimental group=$34.60{\pm}6.35$, Comparison group=$44.63{\pm}9.93$, t=3.552, p<.001) and depression (Experimental group=$10.20{\pm}6.61$, Comparison group=$17.81{\pm}10.85$, t=3.542, p<.001) than the comparison group. Conclusion: The findings from this study showed that cognitive-behavioral counseling applied by nurses is very effective to reduce anxiety and depression among patients with breast cancer. Therefore, providing nursing counseling to broader spectrum of patients with cancer should be considered. Further research would warrant future clinical application of nursing counseling.

Purpose : This study aims to investigate the effect of somatosensory stimulation on the upper limb sensory and function and self-esteem of stroke patients. Methods : This study period was march 4 to april 4 (5 weeks). The subject were 20 stroke patients with somatosensory impairment in B hospital, seongnam, gyeonggi province. They were devided into two group-experimental and control-with 10 members each. The members of the experimental group underwent somatosensory stimulation, whereas the members of the control group underwent an occupation-based intervention for 5 weeks. Thirty-minute therapy was provided 3 times per week for 5 weeks. Before and after the intervention, both groups were evaluated via light touch, static two-point discrimination, stereognosis, Fugl-Meyer assessment (FMA), and self-esteem scale Results : In this study, light touch was not significant in both groups. Static two-point discrimination was significant among the experimental group member's index fingers. Among the control group members, it was significant in the ring finger. The comparison between the two groups was significant in the index finger. The stereognosis results were significant in the experimental group but not in the control group. The comparison between the groups after the intervention was not significant. FMA was significant in the shoulder/ elbow/ forearm (SEF), hand and coordination among the experimental group. Among the control group, it was significant in the SEF and hand. The comparison between the groups was significant in the SEF, hand and coordination. The self-esteem scale results were significant among both groups, and the comparison between the group's score was likewise significant. Conclusion : In conclusion, somatosensory stimulation therapy increases the static two-point discrimination, stereognosis, upper extremity function, and self-esteem of patients with stroke. Therefore, while somatosensory stimulation therapy is not the best therapy, it is one of the best occupational therapies for stroke patients.

Objective : The purpose of this clinical research is the investigation of the effects between acupuncture group(control group) and NURIEYE-1 group (experimental group) in myopia Methods : Comparison clinical study was conducted with the randomly arranged 32 patients for acupuncture group(control group) and NURIEYE-1 group(experimental group). For effectiveness evaluation, eye sight test, MQOL and DITI were tested three times with visits for every 4 weeks. With SAS, Statistical analysis was performed by using paired t-test and two sample t-test. Statistical significance was achieved with less than 5% probability (p<0.05). Result : 1. There was no significant effect from the eye sight comparison between the two group. We had improved results in average with MQOL, however, there was no statistical significance. Though there was also no significant result with DITI average comparison between two group, we witnessed significant effect in some part of MQOL. 2. Nevertheless Periodical comparison test showed weak significance with eye sight and DITI, significant effect was found in some part of MQOL. 3. With periodical comparison tests, there were significant effects in eye sight, MQOL and DITI with the experimental groups and control groups, respectively. Conclusion : There was no significant eye sight improvement. However, with acupuncture point stimulation, we think there are some positive effects for the relaxation of excessive stress in eyes.
