The study aimed to evaluate the effects of the EMDR-IGPT(Eye movement desensitization and reprocessing-integrative group treatment protocol) on the depression, anxiety, post traumatic stress, self-esteem in graduate nursing students. A quasi-experimental study employing a nonequivalent control group and pre-post design was conducted. The participants were graduate nursing students from C university (Experimental group=22, Control group=28). The experimental group participated in the 8 session-EMDR-IGPT for 8 weeks, while control group were treated by waitlist. Data were analyzed using ${\chi}^2-test$, independent t-test, with SPSS 24.0 program. There were significant differences in anxiety(t=-2.50, p<.05) and self-esteem(t=20.78, p<.01) of participants between experimental group and control group after completion of 8 session-EMDR-IGPT. The results indicate that EMDR-IGPT can be used to improve anxiety and self-esteem of graduate nursing students. Furthermore, further study needs to identify the mechanism of the effects of the program.

A video conferencing system provides sharing the conference environment for geographically dispersed computer users who use the audio and video information. But the conventional video conferencing systems have some problems which are dependent on specific software and/or hardware and bound the certain platform and network environment. Furthermore the participants must know the information about other participants before joining the conference session and they have to use the same video conferencing system. This paper describes design and implementation of the video conferencing system on the WWW to solve the mentioned problems. The conference applications are transmitted from a WWW server and executed in the participants Web browsers. The participant can carry out conference services by using only the web browser. The WWW server takes charge of conferencing management including the information related to the participants and provides supported conference tools such as whiteboard, chatting and multimedia controls. Therefore the participants can easily join the conference sessions and perform conference working regardless of network connection situations. We used the Java to implement the seamless session connections and interaction between the conference participants which are the most important when implementing the video conferencing system on the WWW and used the ActiveX technology about the audio and video controls to make it easy the hardware control.

M2M (Machine-to-Machine Communication) refers to technologies that allow wired and wireless systems to communicate with other devices with similar capabilities. M2M has special features which consist of low electricity consumption, cheap expenses, WAN, WLAN and others. Therefore, it can communicate via a network. Also, it can handle itself without a person's management. However, it has a wireless-communicate weakness because of the machine-communicate request, and also it is difficult to administrate and control each other. So In this Paper, It suggests the safety protocol between Device, Gateway and Network Domain in M2M environment. Proposed protocol is based on ID-Based encryption's certificate and creates session key between the Access Server and the Core Server in the Network Domain. It uses that session key for sending and receiving data in mutual, and adds key renewal protocol so it will automatically update discern result. a comparative analysis of the existing M2M communication technologies and PKI-based certificate technology is compared with the proposed protocol efficiency and safety.

The study examined the effects, strength, and weakness of chemical peeling and physical peeling, which are some types of peelings that are commonly used for cosmetic skin management for women. For this study, of which the study period was from November 1 to December 27, 2011, 20 female subjects with the compound skin type were investigated. Ten women were assigned to the chemical peeling group, and the other 10 were assigned to the physical peeling group. The experiment continued for six weeks, with one test session per week, totaling six tests. During each session, a skin measurement instrument was used to measure the oil, keratin, pore, wrinkles, and pigments. The results of the tests showed that, in the case of chemical peeling, both glycolic acid peeling and lactic acid peeling were effective in preserving the skin moisture. With physical peelings, crystal peeling was more effective on wrinkles, while diamond peeling was more effective in keratin and pigment improvement. A comparison of the peeling with different media revealed physical peelings to have more effect on more items, but chemical peeling was more effective in moisture and oil changes.

Purpose: The purpose of this study is to investigate dental students' self-perception of clinical care ability after a denture treatment experience. Materials and methods: Of the 58 fourth-year students at the dental school in 2019, 50 students completed the questionnaire concerning their denture treatment session, including treatment planning and pre-prosthetic treatment (4 questions), clinical and laboratory procedures (20 questions), and students' opinions on clinical denture education (4 questions). Each question was answered on a five-point scale, of which points four and five, "agree" and "strongly agree" respectively, were classified as positive responses while points one and two, "disagree" and "strongly disagree" respectively, were classified as negative. Results: All the items on clinical and laboratory procedures received a positive response rate of over 60%, and the overall self-perception of the students appeared to be positive. However, the questions on the ability to perform denture treatment independently after graduation received only 48% of positive answer. Those on patient management, explanations of denture precautions, customized tray production, boxing, and work model production were answered with the highest positive response rate whereas those on treatment planning, final impression acquisition, and surveying, were the lowest in each session. Conclusion: The dental students with experience in denture treatment generally have a positive opinion of their clinical care ability, but further education may be necessary to improve their ability to treat their patients independently.

The aim of this study was to investigate the effects of virtual reality training on upper extremity function and activities of daily living in patients with sub-acute stroke. The present study enrolled 18 patients with sub-acute stroke. All subjects were assigned into either the experimental group (n=9) or control group (n=9). Both groups received conventional occupational therapy for 30 minutes/day, 5 times a week, for 4 weeks. Additionally, the experimental group performed virtual reality training in each session for 30 minutes/day, and the control group conducted conventional occupational therapy in each session for 30 minutes/day. The outcome measures were performed through the Fugl-Meyer Assessment (FMA) and the Korean-modified Barthel Index (K-MBI) before and after intervention. In results, the experimental group showed significant improvements in the scores of FMA and K-MBI after intervention (p<.05). The control group showed significant improvements in the shoulder/elbow/forearm, wrist, and hand sub-domains of the FMA and K-MBI (p<.05). After intervention, the experimental group showed significantly greater improvements in the total score and in the wrist and hand sub-domains of the FMA than control group (p<.05). These findings suggest that virtual reality training may have positive effects on the improvements of upper extremity function in patients with sub-acute stroke.

Objective : We evaluated the diagnosis, treatment, and long-term results of patients with dural arteriovenous fistula (dAVF), which is a very rare cause of posterior fossa hemorrhage. Methods : This study included 15 patients who underwent endovascular, surgical, combined, or Gamma Knife treatments between 2012 and 2020. Demographics and clinical features, angiographic features, treatment modalities, and outcomes were analyzed. Results : The mean age of the patients was 40±17 years (range, 17-68), and 68% were men (11/15). Seven of the patients (46.6%) were in the age group of 50 years and older. While the mean Glasgow coma scale was 11.5±3.9 (range, 4-15), 46.3% presented with headache and 53.7% had stupor/coma. Four patients (26.6%) had only cerebellar hematoma and headache. All dAVFs had cortical venous drainage. In 11 patients (73.3%), the fistula was located in the tentorium and was the most common localization. Three patients (20%) had transverse and sigmoid sinus localizations, while one patient (6.7%) had dAVF located in the foramen magnum. Eighteen sessions were performed on the patients during endovascular treatment. Sixteen sessions (88.8%) were performed with the transarterial (TA) route, one session (5.5%) with the transvenous (TV) route, and one session (5.5%) with the TA+TV route. Surgery was performed in two patients (14.2%). One patient (7.1%) passed away. While there were nine patients (64.2%) with a Rankin score between 0 and 2, the total closure rate was 69.2% in the first year of control angiograms. Conclusion : In the differential diagnosis of posterior fossa hemorrhages, the differential diagnosis of dAVFs, which is a very rare entity, should be considered, even in the middle and elderly age groups, in patients presenting with good clinical status and pure hematoma. The treatment of such patients can be done safely and effectively in a multidisciplinary manner with a good understanding of pathological vascular anatomy and appropriate endovascular treatment approaches.

The purpose of this study was to determine the effects of 5 weeks self-help management program on reducing depression, promoting Activity of Daily Livings(ADLs), Instrumental Activity of Daily Livings(IADLs), grasping power, hope and self-efficacy for post stroke patients visiting public health care centers in Seoul. This was pre-experimental study, and the subjects were 27 post stroke hemiplegic patients. The program was composed of five sessions and each session had health education on stroke, ROM exercise and recreation. Data were collected from May to November, 2000, and all subjects were asked to complete the Questionnaires, be measured vital signs and grasping power. Data were analyzed with frequency, percent, paired t-test, and Pearson's correlation coefficient using SAS(version 6.12) program. The results were as follows : 1) The scores of ADLs were increased from 27.04 to 28.22 after program, and that was statistically significant(p=.005). 2) The scores of IADLs were increased from 18.70 to 19.78 after program, and that was statistically significant(p=.004). 3) The grasping power of right hand were increased from 21.87kg to 26.93kg after program, and that was statistically significant(p=.002). But the grasping power of left hand were statistically insignificant(p=.919). 4) The scores of depression were decreased from 39.63 to 35.30 after program, and that was statistically significant(p=.030). 5) The scores of hope were increased from 30.89 to 34.15 after program, and that was statistically significant(p=.002). 6) The scores of self-efficacy were increased from 67.70 to 76.37 after program, and that was statistically significant(p=.000). According to the results of this study, the scores of Activity of Daily Livings(ADLs), Instrumental Activity of Daily Livings (IADLs), hope, and self-efficacy and the grasping power were improved and depression was reduced in post stroke patients participating in self-help management program. Therefore we recommend to use self-help management programs as a nursing intervention for the post stroke patient.
