This study aims to analyze the characteristics of reflective thoughts of students during experiments in general physics experiments. The participants were 32 college students, they submitted 10 experiment reports including answers to questions for reflective thinking. The results were as follows: First, students show reflective thinking broadly in the experiment, levels were followed by practical reflection, technical reflection, and critical reflection. Also, they actively accepted the knowledge related to experiments, but were passive in connecting new knowledge and experiences obtained through the experiments or forming new questions. Second, the reflective thinking of students show high correlation with experiments related to prior knowledge or the easy-to-understand process. Third, through the qualitative analysis of open-ended questions, it was confirmed that technical reflection occurs in individual evaluation, practical reflection in group evaluation, and practical reflection and critical reflection in improvement proposal. While the students' reflective thinking were superficial or mainly functional, however, they recursively examined the learning contents and the experimental process concurrently.

Our team carried out a new program for public engagement on nanotechnology in Korea. We chose 22 monitors, who majored in science or technology and graduated from universities long time ago. Most of them were married and housewives. This 'focus group' had not only general knowledge about science or technology but also much interest in social activities. The 167 nanoproducts to be monitored were for daily life, e.g. home appliances (washing machine, refrigerator, water purifier, etc), clothing, cosmetics, food, toy, and others. And the period of it was one month. The monitors had a sheet with 10 questions, and filled them out in essay form. All of them submitted 2~3 sheets every weekend to our team. Before monitoring, our team had a meeting for introduction and explanation about the potential risk of nanotechnology as well as benefits from it. Another meeting was held after finishing monitoring to share their experience one another. The main results of the monitoring were as follows: the number of nanoproducts describing both the definition of 'nano' and the size of nanomaterials was just 2 (1.2%) the number of them explaining the technical methods enough was 15 (9/0%) the number of them accounting for the reason of functional improvement enough was 14(8.4%); the number of them doubtful as if there would be exaggeration or false knowledge was 27 (16.2%); the number of them commenting potential hazards to human health or environment was almost zero; the number of them describing about safety certification acceptable was 9 (5.4%). The monitors made a proposal containing recommendation to Government and industry. The contents were as follows: industry should make the manual in detail and correctly, Describe Certificate detailed and correctly, Do research on risk and toxicity continually, Educate employee about nanoproducts at consumer's center; Government should make indication of nanoproducts compulsory, Appoint Certificate Authority and make Certificate Mark guaranteeing the safety on nanoproducts, Make detailed explanation about nanoproducts compulsory.

The study performed questionnaire to the patients receiving implant operation, who visited dental clinics and hospitals(2 hospitals and 5 clinics) from Jul. 1, 2009 to Sep. 12, 2009 in order to study the factors giving effects to patient's satisfaction in the selection of implant. 145 questionnaire papers collected from patients were analyzed with SPSS12.0 program. The result revealed that the satisfaction with implant operation was usually normal when implant was operated because of tooth extraction due to dental caries and periodontal disease and it was usually high when implant was operated because of wound(P<0.05). When considering each cause of tooth extraction, the satisfaction with pronunciation function was usually normal(P<0.001), the satisfaction with functional part including foreign body sense was very low when the cause of operation was periodontal disease(P<0.01). The satisfaction with hospital environment depending on the cause of hospital selection was usually high when hospital was selected because of doctor's fame. It was low when hospital was selected because it was close to home(P<0.001). The satisfaction with the number of hospital visits depending on the number of implanted teeth was usually low when many teeth were implanted(P<0.01). The analysis on the satisfaction with tooth shape and color showed that the satisfaction was high when '1~2' teeth and 'more than 6' teeth were implanted(P<0.05). In order to improve patient's satisfaction with implant, it is necessary to recognize individual's oral status and request correctly. It is determined that proposal of operation period, number of hospital visits, function and expected aesthetic satisfaction degree will contribute to the improvement of mutual reliance between doctor and patient and post-operation satisfaction degree.

The purpose of this study is to investigate the damage status of wood sleepers on concrete track of urban transit at different locations and to analyze the causes of damages. In addition, the turnout maintenance history during the service period of about 24 years was analyzed in conjunction with the train passing tonnage and that was to compare the current repair history. The most frequent damage components were rail, tie plate, spike and wooden sleeper. And, the damage caused by the defect of the rail fastening system such as spike and tie plate according to the deformation of the wooden sleeper was analyzed as the main type of damage. As a result, the damage of track components of turnout system was on the increase because they are directly affected by the train passing tonnage. The supplementary points of the check sheet for current turnout maintenance were derived and the improvement proposal was suggested based on the research results.

The term "ordinary practice of seaman" is applied to hold the responsibility of those involved in marine accidents. However, there is a concern that the responsibilities of seamen may become unclear as the ordinary practices of the seamen are imposed. In addition, the responsibility for improvement is diluted by mentioning the ordinary practice of seaman when the navigation rules stipulated in the COLREGs is clearly violated. The maritime safety investigation and tribunal system thoroughly analyzes the causes of marine accidents to prevent the recurrence of similar accidents. As one cause that does not contribute to the prevention of the recurrence of similar accidents, it would be appropriate to exclude the term "ordinary practice of seaman" as far as possible. Accordingly, I reviewed the reason for the existence of the maritime safety investigation system and ways to improve the application of the term "ordinary practice of seaman," which is recognized as a customary and an unconventional navigation rule, by examining the theories on the ordinary practice of seaman and analyzing cases of court judgments and decisions in the Korea Maritime Safety Tribunal. I also proposed a modern interpretation on the responsibility for proper and purposeful application. In addition, from the viewpoint of preventing the recurrence of maritime accidents, it is suggested that the nounized term in Korea be replaced with the descriptive term.
