This paper describes our experience to design and implementation of a collaborative system framework that allows to develop certain collaborative applications such as 3D animation, computer game, and industrial design. The collaborative system enables users, who located in geographically long distance, to do collaborative work in a single virtual space. The proposed system basically consists of client and server system. The goal of proposed system is to support scalability, portability, and platform independent. In order to achieve these, the server is implemented in Java platform and is adopted to the hybrid architecture which takes the advantages both in centralized and decentralized collaborative system. We construct the server base on its functional characteristics so called User Manager Server (UMS), Session Manager Server (SMS), and Information Server (IS), The UMS manages the users who are taking part in the collaborative operations. The SMS supports the conferencing in the proposed system. The IS provides the connection methods among the UMSs. For user's convenience, we implement the client using Visual C++ in Windows. We also expend the functions of 3D Studio Max to distributed environment by means of the plug-in module, and facilitate the chatting and white board functions as well.

Objective : The purpose of this study was to investigate the effects of occupational therapeutic intervention including functional task training on activities daily living of falls experienced elderly. Methods : This study used a single subject experimental design with alternating treatment and reversal design. One participant who have had falls experience among the community-dwelling elderly completed. This study a total of 18 sessions were conducted. Fall Efficiency Scale(FES), Berg Balance Scale(BBS) and task modification scale were used to assess the activities of daily living during each session, and Canadian Occupational Performance Measure(COPM) and Assessment of Home-based Activities(AHA) were used to evaluate the activities of daily living at pre-and post-test. Results : The participant showed significant improvements in the FES, BBS scores. However, the improvement was greater when progressive resistance exercise was practised along with functional task training. COPM and AHA scores improved at post-test. Conclusions : These findings provide evidence for occupational therapeutic intervention for falls-experienced elderly.

Authors performed a stereotactic radiosurgery with multiple noncoplanar convergent photon beams of linear accelerator (NELAC-1018 18 MeV, NEC) using a specially designed Yeungnam localization device for two patients with recurrent glioblastoma multiforme. One patient had 2 cm sized and the other 4 cm sized mass on the CT images. After single session of treatment with 15 and 20 Gy, headache was improved in a few days after radiosurgery with no remarkable untoward reactions. Our experience with these two patients were encouraging and we found that our localization device, which is easily adjustable and inexpensive, could be a valuable tool for stereotactic radiosurgery particularly in the treatment of recurrent brain tumor.

This retrospective study assessed the effectiveness and side effects of conscious sedation using chloral hydrate, hydroxyzine, and N₂O/O₂ in the sedation of 149 pediatric patients over 188 sedation sessions, and to identify associated variables. The effectiveness of the sedation was evaluated using the Houpt scale, and was considered effective for scale categories of excellent or good. Effectiveness and side effects were assessed every 15 minutes. The effectiveness decreased and side effects increased over time. The effectiveness of sedation during 60 minutes was 57.4%, and one or more side effects occurred in 18.1% of sessions. Effectiveness of sedation increased with body mass index (BMI). When patients were sedated at the beginning of the procedure, the effectiveness was greater. Side effects increased with patient age. When sedation was divided into two sessions, the number of sedation did not affect the effectiveness or side effects. It can be suggested that sedation should be performed over two separate sessions, as a single prolonged session may lead to reduced effectiveness and increased side effects. To maximize effectiveness and minimize side effects, several variables such as BMI, whether to sedate at the beginning of the procedure and age should be considered thoroughly before sedation.

An 11-year-old castrated male cocker spaniel presented with halitosis, anorexia, and swelling of the left face. Upon physical examination, a firm mass was detected in the left buccal mucosa. Fine needle aspiration cytology revealed a malignant tumor of mesenchymal origin. We performed biopsy, which gave a diagnosis of oral fibrosarcoma. The client refused surgical treatment, and carboplatin chemotherapy (300 $mg/m^2$, IV, q 21 days) was initiated. The mass gradually decreased in size and disappeared about 89 days after the initial chemotherapy. Complete remission was attained, and the tumor did not relapse. This case report shows that a single carboplatin chemotherapy session can achieve macroscopic complete remission of oral fibrosarcoma.

Objective : This study was to verify the effects of occupation-based training with errorless learning and spaced retrieval on task learning and satisfaction of elderly with mild vascular dementia. Methods : The subjects of this study were 3 geriatric individuals with mild vascular dementia, ABA' + follow-up design was used. Intervention period was provided occupation-based training with errorless learning and spaced retrieval. The dependent variable was converted to ability of task performance every session and satisfaction before and after intervention. Result analysis was suggested through visual analysis and bar graph. Results : After the occupation-based training with errorless learning and spaced retrieval, Ability of task performance and satisfaction improved for all subjects. Conclusions : From this study, occupation-based training with errorless learning and spaced retrieval training was found to be an effective mediation for improving independence of task and satisfaction for people with mild dementia. This study could provide evidence for clinical application for occupation-based training.

The internship is essential for the music therapy curriculum and affords interns the opportunity to apply their classroom-based knowledge and skills to real-world clinical settings. However, challenges associated with the internship can result in interns undergoing trial-and-error learning, interpersonal conflicts, and intrapersonal difficulties. An experiential music therapy group may be useful in helping interns process these incidents and develop their personal and professional skills. We explored the experiences of music therapy interns participating in therapeutic song writing. In this study, five music interns completed two 4-hour sessions of therapeutic song writing. Following the second session, a group interview was conducted with participants to gather data on their experiences. The interview was recorded, transcribed, and analyzed. Six themes and 18 sub-themes were derived from the data. The six themes were preconceptions of therapeutic song writing, meaningful lyric creation, challenges in song composition, structured experiences during song writing process, development of self-awareness through music, and relational experiences resulting from the group process. Participants were able to incorporate their individual internship experiences into a single song by communicating with group members during the step-by-step process. Participation in therapeutic song writing was found to help music therapy interns identify and process challenges encountered during their internship and further their personal and professional development.

Micellar catalysis is an essential part of theoretical and experimental curricular. The sodium dodecylsulfate (SDS) catalyzed reaction between glycine and potassium permanganate in acidic medium is an ideal kinetic experiment for the secondary and undergraduate physical chemistry laboratory, to show the effect of micellar catalysis on rate of the reaction. The reaction is conducted both with and without SDS to observe the rate enhancement in the presence of surfactant. To show surfactant catalysis a plot between k and [SDS] is plotted. As surfactant catalysis is observed even before the critical micelle concentration of SDS, this pre-micellar catalysis can be understood in the light of positive co-operativity. The value of positive cooperative index (n) has been found to be 2.37. Further, dependence of the reaction rate on substrate and oxidant concentrations is also discussed. The reaction follows pseudo-first-order kinetics. The overall reaction is second order, with first-order dependence on both glycine and permanganate concentrations. The theory of surfactant catalysis is also discussed. With the conditions specified in the experiment, total reaction times are in 3~4 hours lab session, thus allowing several data sets to be acquired in a single laboratory period. Preparation of solutions and procedure is also given in detail.

This study is an experimental study on the single group pre-post test design for the effects of the food expression activity program on subjective memory, depression, and self-expression of the elderly. 36 elderly people attending Senior Citizen Club from two locations in S City participated. A total of six session programs were applied from January 8 to February 17, 2020. The questionnaire survey conducted subjective momory, depression, and self-expression before and after the program. The contents of the intervention consisted of physical relaxation, cognitive activities, and various food activities. In the result of this study, the food expression activity program were statistically significant differences in subjective memory(t=2.67, p=.011), depression(t=3.88, p<.001), and self-expression(t=2.09, p=.044). Therefore, it is expected that the food expression activity program can be applied as a nursing intervention to reduce depression and improve subjective memory and self-expression in the elders attending senior citizen clubs.
