  • This study examined the knowledge and practices of scientific inquiry displayed by three student teachers and two beginning teachers at secondary levels. Observations using the instrument of OTOP designed by the research team of OCEPT (Oregon Collaborative for Excellent in the Preparation of Teachers) generalized similar teaching strategies of scientific inquiry between student and beginning teachers, such as using group work for students' first hand experience, using concrete materials for experimentation or visual tools for demonstration, using questions for factual knowledge mainly without opportunities to understand how scientific knowledge is constructed. Those scientific inquiry activities were very confirmative ones to follow the steps without opportunities of understanding nature of science or nature of scientific inquiry. However, all participants in this study hold knowledge of scientific inquiry envisioned by the National Science Education Standards [NSES] (NRC, 1996), where students identify their hypothesis, use critical and logical thinking, and consider alternative explanations through argumentation as well as experimentation. An inconsistent relationship between participating teachers knowledge and practices about scientific inquiry resulted from their lack of pedagogy skills of implementing it in the classroom. Providing opportunities for these teachers to reflect on their beliefs and practices about scientific inquiry was recommended for the future study. Furthermore, increasing college faculty interest in new teaching approaches for upgrading the content knowledge of student teachers and beginning teachers was recommended as a solution, since those teachers showed evidence of influence by college faculties at universities in their pedagogy skills.

  • The purpose of the study was to determine the ability of the caries activity test, 'Cariostat' to identify preschool children with dental caries. The subjects of this study were 76 children of 3 to 5 years of age. Oral examination was carried out to assess the caries experience using a mirror and explorer. In all subjects buccal plaque samples were obtained, incubated, and scored as the manufacturer's instructions for the Cariostat test. Statistical analyses were used with the Crosstabulation. The test group exhibited mean dft index 5.21, while 27.63% of subjects were caries free and had no restorations. The sensitivity of the Cariostat test was found to be 98.8% while the specificity was found to be 19.05% The results showed that caries activity measured by visual reading was highly significant to the Cariostat score and dft index(P<0.001). The Cariostat method has indicated the future possible occurrence of caries. The use of this method is meant to require in the caries prevention program.

  • A 60-year-old man was diagnosed with locally advanced non-small cell lung cancer. He refused treatment with a curative aim and was treated conservatively. Pain had developed on his shoulder and chest wall, which became worse as the cancer progressed. Although his pain initially appeared to be relieved with weak opioids and analgesics, it became more severe Strong opioids (transdermal fentanly patch and oxycodone), antidepressant or epidural block were introduced, However, the background pain became more intense and reached up to 8~9/10 on the visual analog scale (VAS). The dose of the transdermal fentanl patch was gradually increased to $600{\mu}g/hr$, which resulted in a dramatic improvement in his pain (9/10 of VAS) to 3/10 for most of the time. We described the successful experience with a high dose transdermal fentanyl patch for cancer pain relief, which might be an alternative option for cancer patients suffering from severe pain.

  • Gianni Versace was a designer who established his unique fashion world by thinking creatively and using rich design sources. The purpose of this study is to present designers a methodology for creative and characteristic design development by searching Gianni Versace's idea source for fashion design. As a method of the study, visual and textual data were investigated for Versace's fashion and design source especially focusing on those elements that inspired him. Versace was born in the southern area of Italy in 1946. Ever since his childhood, he had a lot of experience with clothes because his mother was a dressmaker. His first collection was made in 1978, and Versace became one of the most famous fashion designers in the world within 20 years. He used a wide range of design sources such as history, culture, and art and created his design world with it. He focused on four important epochs. They were classicism, Byzantium, the eighteenth century centering on Baroque, and the 1920s and 1930s centering on Madeleine Vionnet and Madame Gres. Among cultural elements, costume design for ballet and opera and rock 'n' roll music inspired him greatly. Also, Pop art and various paintings such as Chagall's and Delaunay's had a huge effect on Versace. With these elements, he created a bold and unique coordination of style by mixing & matching history, genre, material, and style into his design. Thus he completed an extraordinary and original fashion style by emphasizing on decorative and glamorous points and changing a way of thinking.

  • Purpose : The purpose of this study was to identify and assess factors that may contribute to pain of patients undergoing implant surgery. Materials and Methods: A total of 24 patients who underwent implant surgery were included in the study. Each patient's anxiety was measured using Corah's dental anxiety score(DAS) and modified Spielberger's state-trait anxiety inventory(STAI) immediately after the operation. Also, level of pain was measured using visual analog scale(VAS) during the operation and 48 hours after the surgery. The effect of various factors, such as demographic variables, previous dental experiences and operation time were also analyzed. Results: Postoperative pain levels were relatively low than expected. However, DAS and STAI were high among patients, and it showed that patients had anxieties about implant surgery according to DAS and STAI values. The previous dental experience did not affect the pain level, but the duration of surgery and the presence of accompanied advanced surgery did. Conclusion: To reduce patient's pain, proper management of anxiety will be required and careful attention is needed when performing local infiltration.

  • Background: Despite increasing popularity of dental implants, there is limited information on the pain experience associated with the surgical implant placement under general anesthesia. The aim of this study was to assess the characteristics of patient-reported pain and efficacy of patient controlled analgesia after implant surgery under general anesthesia. Methods: Total 39 patients who underwent implant surgery under general aensthesia were enrolled. In PCA group (n=30), patients received patient controlled analgesia (fentanyl 700 mg and ketorolac 150 mg) set to basal rate 1 ml/h, bolus 1 ml, and lockout interval 10 min. In control group (n=9), patients received ketorolac 30 mg intravenously when they feel painful. We evaluated pain intensity using VAS score at the end and after 12 hr of the operation and recorded the number of bolus injection as a surrogate of rescue therapy. We compared the VAS data, the frequency of complication between two groups. Results: The self reported pain was highest at 1 hous after surgery in both groups. However, the intensity was not severe (PCA group = 5.7, control group = 5.6), and decreased gradually thereafter. Total demand bolus number was less than 6 in nearly 65% patients. And there was no significant difference in the frequency of complications such as nausea, vomiting and dizziness between both groups. Conclusions: The Pain following the surgical placement of dental implants was generally mild and gradually decreased with time. There was no difference in complications between control group and PCA group.
