The purpose of this study was to analyze of how the elementary school teachers lead their classes of a science laboratory instruction and an engineering laboratory instruction in a science subject class. For this study, science laboratory and engineering laboratory lessons were selected and for each science and engineering laboratory lesson, five elementary school teachers were video-recorded of their lessons. The science and engineering laboratory lessons were analyzed by utilizing processes of the science model and the engineering model based on Schauble et al. (1991). The results of these studies are as follows: In science laboratory instruction, some participants didn't distinguish the difference between the science laboratory goal and the engineering laboratory goal. All of participants used search and end strategy of engineering laboratory for science laboratory lesson. In engineering laboratory instruction, all of participants guided to students engineering laboratory goal and used inferences and search strategy of engineering laboratory. However they didn't use the trial and error strategy or redesign which can be an essential element in engineering and design process. Educational implications are discussed.

Objectives To make comprehensive feature of clinical trials using herbal medicine and their results by today, then help a strategy for herbal medication-derived clinical studies in the future. Methods Through medical website (Pubmed EBSCO Medline), foreign clinical literatures about atopic dermatitis and herbal medicine were searched. And domestic clinical literatures about atopic dermatitis using internet website (OASIS) and hand-searching. Analysis was performed according to distribution mainly by subject, study design, number by year and its efficacy. Results and Conclusions Seventy-nine (Domestic literatures: Fifty, Foreign literatures: Twenty-nine) literatures were selected according to inclusion criteria of clinical study. 80% of domestic clinical literatures were observational studies, 50% of foreign were intervention. There were six adverse effect case studies, two follow-ups, one case report, four translational and four uncontrolled clinical trials in foreign literatures. And nineteen case reports, eighteen case series, two follow-up and five uncontrolled clinical studies in domestic. Six RCTs have established by four external herb therapy and two decoctions in Korea, showed positive effects. Three out of four external applications RCTs, four out of seven decoctions showed positive results in foreign studies. This study revealed the current status of atopic dermatitis clinical research using herbal drugs. To put clinical trials to use of herbal medicine in the treatment atopic dermatitis, scientific and objective-based studies should be needed.

The purpose of this study was to analyze the status of environment-related teaching in elementary and secondary schools. A questionnaire survey was conducted for the study. Items in the questionnaire were developed based on the theory of environmental education and integrated education. The questionnaire was responded to 501 elementary school teachers, 273 middle school teachers, and 210 high school teachers in the city of Seoul and Kyunggi Province. The survey analysis revealed that elementary and secondary school teachers recognized 'environmental action skills' as the most important objective for school environmental education. Contrary to the teachers' expectations, it was found that there is insufficient teaching and learning materials for teaching in the domain of 'environmental action skills' and they could not confidently teach the skills in environment-related classes. For professional development of teachers in integrated environmental education, pre- and in-service programs will be developed systematically in a workshop to give teachers an opportunity to analyze teaching materials, design instruction plan, perform class trial, and evaluate the class situation for feedback. The results of this study can serve as a basic reference for improvement of environment-related subject education.

Objectives : Hwabyung is one of well-known mental health problems like depression in Korea and it's concept is generated from oriental medicine. We suggest that clinical practice guideline should reflect the Hwabyung's characteristics, clinical environment and Oriental medical doctor's need. Methods : We use the general development method of clinical practice guideline and also apply the oriental medicine's properties. Results : We need to refer to the western psychiatric field, especially the clinical guideline of depression. And we should base on the clinical survey and trial with the selected core subject considering oriental medicine's character. Conclusions : From this development, we expect the application of proper clinical decision by medical team, the objectification of oriental medicine, and the improvement of medical quality in the clinical field of oriental medicine.

The purpose of this study is developing a method to analyze and evaluate a golf swing motion using the ground reaction force (GRF) data. Proper weight shifting is essential for a successful shot in golf swing and this could be evaluated by means of the forces between the feet and ground. GRF during the swing were measured from 15 low-handicapped male golfers including professionals. Four clubs(driver, iron 3, iron 5, and iron 7) were selected to analyze the differences due to different characteristics of club. Swings of each subject were taken using a high speed video camera and GRF data were taken simultaneously by two AMTI force platforms. To simplify the GRF data, forces of the three major component of GRF(vertical, lateral, anterior-posterior force) at 10 predefined temporal events for each trial were selected and the mean of each event were calculated and evaluated. Analyzed vertical GRF (VGRF) data could be divided into two different styles, one-legged and two legged. One-legged style shows good weight transfer to the target leg and most of the previous study shows this style as a typical pattern of good players. Therefore the data from the iron 5 swing obtained from 10 one-legged style golfers are provided as criteria for the evaluation of a swing.

The purposes of this study were to find out an evaluation scale that could predict wear comfort and to investigate the effect of the skin-contacting fiber type on the subjective sensation and microclimate. Sensorial evaluation was basically followed by the Human Perception Analysis (HPA) interviewing 144 consumers. Sixteen female subjects were participated in the sleeve wear test with and without wearing vapor permeable water repellent outerwear. Experimental sleeves were constructed using the same double knit by turning inside out to control other material effects except the skin-contacting fiber type, hence each different side of double knit, cotton side and the cotton/polypropylene blend side, was next to skin in each trial of the experiment. As results, it was noted that the term representing a combined feeling of thermal and wetness sensation, and muggy appeared to be a powerful language to measure perceptual responses of human subject among five dimensions of evaluation. although the ordinary users did not use the term very often. As for the comfort properties of double knits, it seemed that subjects slightly more preferred polypropylene/cotton blend to cotton as the skin-contacting fiber type when they wore outerwear and their skin were covered with sweat, although the result was rot statistically significant and need to be confirmed under higher work load.

Background: The purpose of this study was to investigate the effects of ipsilateral and contralateral load changes during single-leg standing on the leg muscle activities of healthy people. Design: Randomized controlled trial. Methods: For all the subjects, a load was randomly applied to the ipsilateral or the contralateral side. While the load was applied, the subject raised a hand and then performed single-leg standing for 10 seconds using the dominant side. Results: During single-leg standing, the muscle activity of the gluteus medius, peroneus longus on the supporting side increased statistically significantly when an upper limb load was applied contralaterally, but no statistically significant differences were detected in the muscle activities of the tibialis anterior and the gastrocnemius using a test of within-subjects effects. Conclusion: It can be seen that muscle activities increase during exercise when the amount and frequency of a load are increased and when the same load is applied to different sides of the body. Such muscle activity increases may be applied to change the intensity of exercise when one is in a static posture, such as during single-leg standing.

Background : There have been very few studies conducted on the number and type of microorganisms that remain on the ring finger after handwashing. This study was performed to investigate whether there were changes and differences in the type and number of microorganisms on the ring finger before and after handwashing. Method : The subjects of the study were 15 MICU and SICU staff nurses who were wearing rings. I swabbed two different fingers of the same hand with cotton balls. One finger which had a ring and the other with no ring. I swabbed the fingers of each subject three times(before handwashing, after handwashing with soap, and after handwashing with bethadine solution). After storing them for 48 hours in an incubator, I sent them to the laboratory and recorded the culture results. Results : There was no difference in the type of microorganism, but a major difference in the number of the microorganisms that existed on the finger ring. The results showed that there were much more microorganisms on the ring fingers than on the fingers that did not have rings both before and after handwashing. This tendency was consistent regardless of the handwashing agent. I therefore recommend that all nursing staff who work in general nursing units, as well as nurses who work in the ICU, remove their rings when taking care of the patients.

Judgment on the validity of patents on the subject of an arbitration does not. In other words, the occurrence of patents generated by the administrative action, and such administrative action by an authorized agency may be treated as legitimate until it is canceled. However, recent Supreme Court judgment on novelty and inventive step as well as judgments about the validity of the patent also made possible by the judiciary. This progress even in the mediation of an arbitral award which is premised on the validity of patents can be seen that possible. However, if the arbitration by an arbitrator if possible a certain portion of the limit exists. In other words, the effect of arbitration between the parties is valid. This patent is valid and invalid in arbitration even if the judgment relative to the effect ceases. In addition, the arbitration award and patent invalidation trial is in progress at the same time, if you consequently will reach a different conclusion. This can cause problems of double track. In addition, by extending the critical target recognition and enforcement in other countries can cause problems. Despite these problems, now about the validity of patents that it is possible intervention is necessary to discuss again.
