Purpose : To evaluate the functional and radiographic outcome of the modified Bosworth method in the surgical treatment of acute type V acromioclavicular joint dislocation. Materials and Methods: From June 1995 to May 1998, 20 patients were operated on for acute and complete acromioclavicular dislocation(Rockwood type V). The operative technique includes fixation of the coracoclavicular joint with Bosworth screw or 6.5mm cancellous screw and imbrication of trapezius and deltoid muscles. The average age was 34 years(range, 19 to 51 years). These 20 patients with an average follow-up of 18months, were evaluated clinically using the UCLA scoring system. Additional radiographical assessment was performed with stress radiographs. Results: Excellent or good clinical results were obtained in 95%(19 cases). And the average coracoclavicular interval ratio was decreased from 3.31(2.2-6.0) to 1.13(1-1.4) in stress radiographs. There were 4 cases of hetero­topic calcification postoperatively but there was no correlation with clinical result. Posttraumatic A-C joint arthritis was developed in one case. In that case, the distal clavicular resection was done under the arthroscopic technique. Conclusion: The severe displacement observed with type V injuries is incompatible with normal shoulder function if the shoulder is left in its displaced position. In type V injuries, significant damage to the deltoid and trapezius musculature and overlying fascia occurs, therefore open reduction and good fixation must be obtained with imbrication of trapezius and deltoid muscles. In our type V acute complete acromioclavicular dislocation, the modified Bosworth technique provides excellent results with a low complication rate.

Oronasal fistula are a well-known complication of surgical treatment of cleft palate, occurring most frequently in the alveolus and hard palate. Previous reports have demonstrated that oronasal fistulas, particularly if greater than l cm in diameter, had an adverse effect on speech. The aim of this study was to demonstrate the relationship between the size of the fistula and the influence on velopharyngeal function. The site and size of the fistula were indicated on graph paper with calipers and measured in $mm^2$. Speech assessment was carried out using a Nasometer, VPI articulation differential test, spectrography. Patient whose fistulas affected their speech had significantly larger fistulas than those whose fistulas did not. The study shows that the larger the fistula, the greater the risk of hypernasality and nasal emission, but even small fistulas can cause speech problems. If obstruction of the nasal passage is eliminated in a patient with a previously asymptomatic fistula, it may result in a fistula becoming symptomatic, resulting in hypernasality and nasal emission. In conclusion, even small fistulas can influence speech production and should be considered before any treatment is planned. The study lends support to early closure of oronasal fistulas, particularly before pharyngeal flap surgery is contemplated.

Objectives : This study was to assess the effectiveness of Oriental medical treatment on carpal tunnel syndrome, comparing its outcome with that of Western medical treatment. Methods : After being diagnosed with carpal tunnel syndrome by electromyography, subjects were enrolled in Kyung Hee Medical Center from March 2006 to January 2007. We prescribed Kejibokryung-hwan to the Oriental medical therapy group (OM group) and NSAIDS to the Western medical therapy group (WM group). Effectiveness was assessed by degree of pain using visual analog scale (VAS) before and after 3 weeks' treatment. Adverse effects were also monitored. Results : There were 21 patients in the OM group and 19 in the WM group. No statistical significant difference was detected at the baseline assessment. After 3 weeks of medication, pain was reduced about 26% in the OM group and 46% in the WM group. These findings might be explained by that more than half of the WM group received local steroid injection, which has been known to have more rapid analgesic effect that oral medication. Although pain reduction rate was higher in the WM group than in the OM group, we suggest that Oriental medical treatment is still effective, faking into consideration the fact that completely recovered cases were found only in the OM group. No adverse effect was found in either of the groups. Conclusion : This work could help us to understand the effectiveness of Oriental medical treatment on carpal tunnel syndrome.

The purpose of this study is to identify the educational needs among social workers in social welfare facilities in Jeju province concerning lack of knowledge, skill and attitude, and establish the systematic education for prosecuting diverse training and suggest fundamental data for designing future curriculum. The results of analyzing top 10 educational needs for the workers are as follows: firstly technics for managing crises, understanding and practice for clients (characteristics, human right, safety and health), case management (basic), counseling technique (basic), case management (advanced), counseling technique (advanced), planning and operating social welfare program, managing client response and emotional labor, improving competence for communication (between staffs and clients, etc.), and finally assessing project outcome (project plan, execution, management and assessment, etc.). Social workers in social welfare facilities in the area have highly recognized the necessity of profession centred education. However, they had low satisfaction with the diversity of profession education in the Jeju island and the systematic training courses. This survey suggests the various results concerning qualitative growth of profession education, expansion of job-centred curriculum and security of professional instructors to fulfil systematic education training for social workers.

This study examined student- and school-level background and ICT factors that affected PISA 2015 Collaborative Problem Solving (CPS) for Korean students (4863 students from 142 high schools). A two-level hierarchical linear model (HLM) was analyzed from the basic model (model 1) with no predictors to the final model (model 5) with all predictors. Results showed that first, gender, socioeconomic/cultural backgrounds, cooperation level positively predicted CPS scores while perceived unfairness of teacher negatively predicted the outcome. Second, the more frequently ICT was used for out-of-school learning purposes, the less frequently ICT was used for entertainment purposes, and the less frequently ICT was used in schools, the higher CPS scores were. Considering ICT autonomy and social interaction variables measured for the first time in PISA 2015, students who were more interested in ICT and more autonomous in using ICT devices achieved higher CPS scores. On the other hand, the more students considered ICT important as social interaction, the less they gained CPS scores. Third, in terms of school-level characteristics, the smaller the students behavior detrimental to learning, the higher the teachers perceived positive working environment, and the fewer the number of computers available per student, the higher CPS scores were. To facilitate computer-based collaborative problem-solving competence, it is important for students to have interest and autonomy in using ICT. In addition, the guidelines of ICT use and SW curriculum need to be established in order to increase the effectiveness of using ICT device in school.

Purpose: The purpose of this study was to assess the 2-year follow-up results of patients with a trimalleolar fracture, who had undergone an anterior incision cannulated screw fixation of the posterior malleolar fragment, which had more than 25% of articular involvement or had no cortical continuity with the distal tibia. Materials and Methods: Among 28 patients with a trimalleolar fracture who had undergone fixation of the posterior malleolar fragment between February 2005 and February 2010, 14 patients, who underwent an anterior incision cannulated screw fixation of posterior malleolar fragment and were followed-up for more than 2 years, were selected. The postoperative clinical and radiological findings immediately and at the 1- and 2-year follow-up were compared. The clinical findings were evaluated as American Orthopaedic Foot and Ankle Society (AOFAS) score. The radiological assessment was evaluated as the maintenance of reduction, period to bone union, and the presence of nonunion, malunion, and complications. Results: The clinical outcome by mean AOFAS score revealed 83.0 points in the group with preoperative displacement below 2 mm and 80.7 points in the group with preoperative displacement above 2 mm postoperatively. The mean AOFAS score was 91.7 and 93.1 points in the group with preoperative displacement below 2 mm on 1- and 2-year follow-up, respectively, and 89.8 and 91.7 points in group with the preoperative displacement above 2 mm on 1- and 2-year follow-up, respectively. After a 2-year follow-up among 14 cases selected for this study, 13 cases showed an excellent reduction state and only 1 case (7.1%) showed a displacement of more than 2 mm. No complication were encountered in the group with preoperative displacement below 2 mm. On the other hand, among 8 patients in the group with preoperative displacement above 2 mm, there were 3 with limitations of the range of motion of the ankle joint (37.5%) and 1 post-traumatic arthritis (12.5%) at the 2-year follow-up. Conclusion: Anterior incision cannulated screw fixation of the posterior malleolar fragment could be a valuable method for the treatment of trimalleolar fractures that provides satisfactory results.

Background: The survival of non-small cell lung cancer (NSCLC) patients with brain metastases is reported to be 3~6 months even with aggressive treatment. Some patients have very short survival after aggressive treatment and reliable prognostic scoring systems for patients with cancer have a strong correlation with outcome, often supporting decision making and treatment recommendations. Methods: A total of one hundred twenty two NSCLC patients with brain metastases who received gamma knife radiosurgery (GKRS) were analyzed. Survival analysis was calculated in all patients for thirteen available prognostic factors and four prognostic scoring systems: score index for radiosurgery (SIR), recursive partitioning analysis (RPA), graded prognostic assessment (GPA), and basic score for brain metastases (BSBM). Results: Age, Karnofsky performance status, largest brain lesion volume, systemic chemotherapy, primary tumor control, and medication of epidermal growth factor receptor tyrosine kinase inhibitor were statistically independent prognostic factors for survival. A multivariate model of SIR and RPA identified significant differences between each group of scores. We found that three-tiered indices such as SIR and RPA are more useful than four-tiered scoring systems (GPA and BSBM). Conclusion: There is little value of RPA class III (most unfavorable group) for the same results of 6-month and 1-year survival rate. Thus, SIR is the most useful index to sort out patients with poorer prognosis. Further prospective trials should be performed to develop a new molecular- and gene-based prognostic index model.

This research intends to suggest the ways to improve protected area management in Korea. To this end, the current protected areas appointed in the nation and their management has been examined, and the problems of management have been identified by means of a field research of protected areas and a survey. In addition, a scheme for an integrated management system has been suggested for management improvement, and a management plan guide, as well as after-evaluation guide, has been suggested. The outcome of the research is as follows. First, the protected area management plan is needed since the protected area in our nation is not managed in a proper way after being appointed as such. Second, when making a management plan, a management organization should make a management plan that can attract voluntary participation from stake-holders by means of efficient communications with them. Third, to maintain the management plan in a consistent and systematic way, related policy, law, and institutions should be (re)formulated. Fourth, an organization responsible only for management of protected areas should be established in consideration of management inefficiency due to the overlapped appointment of managing the protected area. Fifth, the management plan guide and after-evaluation guide can be used for effective protected area management. The results of this study are expected to be helpful for creating a management improvement scheme to address the problems related to the protected areas in our nation. But, it is required to review the guides for the management plan and after-evaluation, and consistent and systemic support from the government in such areas as legislation and policy are also in great need.

The purpose of this study was to examine the effect of backward walking training on the balance capability(Functional Gait Assessment; FGA, Timed Up & Go Test; TUG) and gait performance(10 meter Walking Test; 10 mWT) of stroke patients. Eighteen with stroke patients were randomly allocated to an experimental and contral group of nine patients each. both groups received general neurorehabilitative physical therapy for 45 minutes per day 5 times per week during 4 weeks. The experimental group also performed additional backward walking training for 20 minutes per day 3 times per week during 4 weeks. There were signicantly increase by backward walking training in outcome of the balance capability from the FGA was increase from $17.67{\pm}1.00scores$ to $19.22{\pm}1.00scores$(p<.05), TUG was decrease from $26.45{\pm}1.37sec$ to $23.28{\pm}1.35sec$(p<.05) and 10 mWT was decreased from $21.74{\pm}1.35sec$ to $18.33{\pm}1.10sec$ (p<.05). These result suggest that backward walking training for stroke patients is effective in improving balance capability(FGA, TUG) and gait performance(10 mWT).

Periodontal surgery as part of the treatment of periodontal disease is mainly performed 1) to gain access to diseased areas for adequate cleaning; 2) to achieve pocket reduction or elimination; and 3) to restore the periodontal tissues lost through the disease; i.e., a new attachment formation of periodontal regeneration. To accomplish the latter, often referred to as the ultimate goal of periodontal therapy, a number of surgical procedures have been advocated throughout the years. Clinical studies have demonstrated that considerable gain of clinical attachment and bone can be achieved following guided tissue regeneration (GTR) therapy of intrabony defects. The aim of this study was to analyse the radiographic bone changes 2-year after GTR using a bone graft material and nonresorbable membrane. Patients attending the department of periodontics of Kyungpook National University Hospital were studied. Patients had clinical and radiographic evidence of intrabony defect(s), 33 sites of 30 patients aged 32 to 56 (mean age 45.6) were treated by GTR with a bone graft material and nonresorbable membrane. Baseline and 2-year follow-up radiographs were collected and evaluated for this study. Radiographic assessment includes a bone fill, bone crest change, defect resolution, and % of defect resolution. Pre- and post-treatment differences between variables (maxilla and mandible, defect depth, defect angle, bone graft materials) using the paired t-test were examined. We observed $2.86{\pm}1,87mm$ of bone fill, $065{\pm}0.79mm$ of crestal resorption, $3.49{\pm}2.11mm$ of defect resolution, and $44.42{\pm}19.51%$ of percentage of defect resolution. Mandible, deeper initial defect depth, narrower initial defect angle showed greater bone fill, defect resolution, and % of defect resolution. But no difference was observed between xenograft and allograft. Outcome of GTR as a therapy of intrabony defect was better than other therapy, but herein, good oral hygiene maintenance as a anti-infective treatment and periodic recall check of patients are essential.
