  • In the new web based learning environment which has recently emerged, a variety of new learning objectives and teaching methods suited to this learning environment have been adopted. Recently, web based project-based learning methods have received a great deal of attention from those wishing to improve learning performance. The objective of this study is to identify the impact of characteristics of communication media and instruction behavior on collaborative interaction and project performance through web based group projects. The characteristics of communication media were divided into richness, flexibility, and ease of use, and the characteristics of instruction behavior were divided into support and expression, which are independent variables. Collaborative interaction as a mediate variable, was divided into information sharing and negotiation. Project performance was the dependent variable. To verify the proposed research model empirically, an experiment was conducted in which learners participated in on-line and off-line courses with group projects. The group project was conducted virtual product development(VPD), and designed a web-site about the VPD. At the end of the project, a survey was conducted. Of the 270 students, 239 responded. The students were assigned to groups of 3 or 4 members, and represented different genders and levels of computer competence. The reliability, validity, and correlation of research variables were analyzed using SPSS 14.0, and the measurement model and the structural goodness-of-fit of the research model were verified through SEM analysis using Lisrel 8.54. We found important results as follows; First, richness and ease of use has positive impacts on each of sharing information and negotiation. This suggests that richness and ease of use are useful in sharing information which is related to the task and agreeing in opinions among group members. However, flexibility has not positive impacts on sharing information and negotiation. This implies that there is no great difference in performance of PC and information literacy of user. Second, support and expression of instructor have positive impacts on sharing information and negotiation. This indicates that instructors play an important role in encouraging learners to participate in the project and communicating with them, sharing information related to the project, making a resonable decision and finally leading them to improve a project performance. Third, collaborative interaction has a positive impact on project performance. This result shows that if the ability to share information and negotiate among students was improved then a project performance would be improved as well. Recently, in the state of revitalized web based learning, it is opportune that web-based group project is practically conducted, and the impact of characteristics of communication media and characteristics of instruction behavior on sharing information, negotiating among group members and improving a project performance is verified. On the basis of these results, we propose that forms of learning, such as web based project, could be one of solution which is to enforce interaction among learners, and ultimately improve learning performance. Moreover web-based group project is able to make up for a weakness which makes it difficult to make interpersonal relations or friendship among learners in computer mediated communication or web based learning.

  • Objective: To explore the perception of drug utilization review (DUR) system and DUR modernization pilot project among healthcare professionals and patients. Methods: We conducted 8 times of focus group interviews (FGI) between August 1, 2019 to December 31, 2019. The healthcare professionals and patients who participated in the DUR modernization pilot project were included in the present study. Based on the type of project participation or medical institution, the participants were divided into the following four groups: group 1, hospital; group 2, clinic; group 3, pharmacy; and group 4, patient. Within each group, interviews were conducted under a pre-defined agenda to identify the implicit perceptions of the participants; the contents of the interviews were, then, categorized. Results: Healthcare professionals established a consensus on the positive aspects of the DUR system and DUR modernization pilot project. However, substantial concerns remain, such as additional workload associated with monitoring adverse events or acquiring consents from patients. Furthermore, a difference of opinion over the DUR convenience system was observed. Among 3 DUR convenience system, the personal medication history review service was highly utilized, but pop-up hold function and communication system was rarely used. Conclusion: We observed that systematic intervention using the DUR system is effective for both healthcare providers and consumers. Adverse events caused by inappropriate drug use can be prevented by continuous patient monitoring. Therefore, the role of DUR system needs to be expanded to establish a safe drug management system.

  • Objective : Because the cause and etiology of chronic headache is not yet fully explained, the treatment of this symptom is not simple. This study compares the effects of aroma acupuncture and normal acupuncture applied on chronic headache patients, in order to establish a primary data for further studies of new treatments and developments of new practical acupunctures. Methods : 38 clinical experiment participants were gathered and through a questionnaire patients who experienced headache for more than 4 hours a day and more than 15 days per month were qualified as Chronic Headache patients. The qualified patients were classified in to two groups, aroma acupuncture group(Aroma AT group, n=23) and normal acupuncture group(AT group, n=15). Treatment was applied 2 times a weeks for 8 weeks. The acupoints, GV20, HN23, ST8, HN46, TE17, GB20, LI20, LI11, LI14, ST36, and LR3 were stimulated for 20 minutes in both the groups. The effects of both groups were analyzed using VAS scores and BPI (Brief Pain Inventory). Results : The VAS pain scores improved significantly in both groups. The decrease rate was larger in the Aroma AT group(p<0.05). The BPI scores for the both groups also decreased. The improvement in the Aroma AT group was larger(p<0.05). Conclusion : Aroma acupuncture applied on chronic headache patients showed effects of relieving pain, improving general activities, changing the mood, and improving sleeping behaviors. These effects were analyzed using VAS scores and BPI. The Aroma AT group showed significant changes of VAS and BPI compared to the AT group, suggesting that this new practical acupuncture is very effective when treating chronic headaches. Further researches are needed to evaluate the distinct functional mechanism of aroma acupuncture, but this study is meaningful in the sense that it will act as a fundamental study to build on.

  • Calcium carbonate(CC) is biocompatible and gradually absorb to be replaced by bone when implanted into bone tissue. Fibrin-fibronectin sealant system (FFSS) is a product of human-derived plasma. The effect is hemostasis, tissue fixation and adhesion, We expect synergic effects of this two materials in periodontal regeneration. When FFSS was grafted with bone graft in intrabony defects, could be eliminated exofolication of bone graft materials. This study evaluated above materials for periodontal regeneration of 6mm intrabony defects in 36 patients. lap surgery was carried in 14 defects of control group. experimental group 1 was 11 defects grafted with calcium carbonate, experimental group 2 was 11 defects which were grafted with calcium carbonate with FFSS. The clinical parameters evaluated included changes in attachment level, probing depth, gingival recession at 6 months. Postsurgery probing depth reduction was 3.1 ${\pm}$ 0.9mm in control, 3.8 ${\pm}$ 1.6mm in experimental group 1, 4.1 ${\pm}$ 1.1mm in experimental group 2. The result clinically and statistically improved compared to baseline(P<0.01), but the difference found among the groups were not statistically significant. Postsurgery clinical attachment level was 1.6 ${\pm}$ 1.2mm in control, 3.5 ${\pm}$ 2.0mm in experimental group 1, 3.3 ${\pm}$ 1.2mm in experimental group 2. All of the control and experimental groups resulted in a statistically significant reduction from baseline(P<0.01). The reduction of the experimental groups were statistically significant from control(P<0.05). But the change between experimental group 1 and experimental group 2 was not statistically significant. We conclude that mixture of CC and FFSS is effective to periodontal regeneration in intrabony defect.
