A large portion of college students show dissatisfaction with their majors. This study presumed that this satisfaction might be caused by discrepancy between major and aptitude and that the problems of this students might be serious. In these regards, this study was attempted to search for the causes of the problems and to develop a small group counseling program for solving them. This study is composed of two substudies. The first part of this study was to examine systematically the variables related to their dissatisfaction with their majors, on the bases of the expectancy motivation theory of organizational behavior. Subjects were 500 juniors, selected from 10 departments of Chon-buk National University. The dependent variables were measured by three. subscales taken from the Program Evaluation Survey. They included the satisfaction with intellectual level of major curriculum, the satisfaction with student-faculty relationships, and the general interests of major academics. Four independent measures were also collected, including major-related expectancy, central life interests, academic achievement, and aptitude. The results of this study were summarized as follows: 1) Consistent with the expectancy motivation model, the central life interests, major-related expectancy, and academic achievement were all a significant predictors of the subscales of satisfaction with majors, in group as well as individually, and these predictor variables also revealed differentiated effects on each of three dependent variables. 2) Contrast with the selected model, academic achievement revealed no significant relationship to the expectancy variables, except for the central life interests. The second part of this study was to develop a small group counseling program, through which students might perform successfully their own major tasks, overcoming their dissatisfaction caused by the major-aptitude discrepancy, and to examine its effectiveness in practice. Based on the conceptual nature of group counseling, group counseling theories and group career development programs, and group-establishing processes, this study developed a group counseling program for major-aptitude development. Subjects were 10 freshmen and 10 juniors, who had thought their majors were inconsistent to their central life interests. They worked through the program two hours a week six weekly long. This study has shown the following facts : 1) The program increased significantly their satisfaction with majors. This result was true equally for each subscore as well as the total score of the satisfaction scale. 2) Also, the effect of program differed significantly by sex and grade, but was not differentiated by grade alone. On the bases of these findings, finally, this study suggested some of research problems, which need to be investigated in future studies on major-adjustment programs for college students with major-aptitude discrepancy.

Dae-Jean Jo,Jae-Kyun Jun,Ki-Tack Kim,김성민 대한신경외과학회 2010 Journal of Korean neurosurgical society Vol.48 No.11

Objective : To evaluate the clinical and radiological outcomes of lumbar interbody fusion and its correlation with various factors (e.g., age,comorbidities, fusion level, bone quality) in patients over and under 65 years of age who underwent lumbar fusion surgery for degenerative lumbar disease. Methods : One-hundred-thirty-three patients with lumbar degenerative disease underwent lumbar fusion surgery between June 2006 and June 2007 and were followed for more than one year. Forty-eight (36.1%) were older than 65 years of age (group A) and 85 (63.9%) were under 65years of age (group B). Diagnosis, comorbidities, length of hospital stay, and perioperative complications were recorded. The analysis of clinical outcomes was based on the visual analogue scale (VAS). Radiological results were evaluated using plain radiographs. Clinical outcomes,radiological outcomes, length of hospital stay, and complication rates were analyzed in relation to lumbar fusion level, the number of comorbidities, bone mineral density (BMD), and age. Results : The mean age of the patients was 61.2 years (range, 33-86 years) and the mean BMD was -2.2 (range, -4.8 to -2.8). The mean length of hospital stay was 15.0 days (range, 5-60 days) and the mean follow-up was 23.0 months (range, 18-30 months). Eighty-five (64.0%) patients had more than one preoperative comorbidities. Perioperative complications occurred in 27 of 133 patients (20.3%). The incidence of overall complication was 22.9% in group A, and 18.8% in group B but there was no statistical difference between the two groups. The mean VAS scores for the back and leg were significantly decreased in both groups (p < 0.05), and bony fusion was achieved in 125 of 133 patients (94.0%). There was no significant difference in bony union rates between groups A and B (91.7% in group A vs. 95.3% in group B, p = 0.398). In group A,perioperative complications were more common with the increase in fusion level (p = 0.027). Perioperative complications in both groups A (p =0.035) and B (p = 0.044) increased with an increasing number of comorbidities. Conclusion : Elderly patients with comorbidities are at a high risk for complications and adverse outcomes after lumbar spine surgery. In our study, clinical outcomes, fusion rates, and perioperative complication rates in older patients were comparable with those in younger populations. The number of comorbidities and the extent of fusion level were significant factors in predicting the occurrence of postoperative complications. However, proper perioperative general supportive care with a thorough fusion strategy during the operation could improve the overall postoperative outcomes in lumbar fusion surgery for elderly patients.

Jo, Dae-Jean,Seo, Eun-Min,Kim, Ki-Tack,Kim, Sung-Min,Lee, Sang-Hun The Korean Neurosurgical Society 2012 Journal of Korean neurosurgical society Vol.52 No.5

Objective : To present the accuracy and safety of cervical pedicle screw insertion using the technique with direct exposure of the pedicle by laminoforaminotomy. Methods : We retrospectively reviewed 12 consecutive patients. A total of 104 subaxial cervical pedicle screws in 12 patients had been inserted. We also assessed the clinical and radiological outcomes and analyzed the direction and grade of pedicle perforation (grade 0: no perforation, 1: <25%, 2: 20% to 50%, 3: >50% of screw diameter) on the postoperative vascular-enhanced computed tomography scans. Grade 2 and 3 were considered as incorrect position. Results : The correct position was found in 95 screws (91.3%); grade 0-75 screws, grade 1-20 screws and the incorrect position in 9 screws (8.7%); grade 2-6 screws, grade 3-3 screws. There was no neurovascular complication related with cervical pedicle screw insertion. Conclusion : This technique (technique with direct exposure of the pedicle by laminoforaminotomy) could be considered relatively safe and easy method to insert cervical pedicle screw.

Development of Postdural Puncture Headache Following Therapeutic Acupuncture Using a Long Acupuncture Needle

Jo, Dae-Jean,Lee, Bong-Jae,Sung, Joon-Kyung,Yi, Jae-Woo The Korean Neurosurgical Society 2010 Journal of Korean neurosurgical society Vol.47 No.2

Acupuncture appears to be a clinically effective treatment for acute and chronic pain. A considerable amount of research has been conducted to evaluate the role that acupuncture plays in pain suppression; however, few studies have been conducted to evaluate the side effects of the acupuncture procedure. This case report describes a suspected postdural puncture headache following acupuncture for lower back pain. Considering the high opening pressure, cerebrospinal fluid leakage, and the patient's history of acupuncture in the lower back area, our diagnosis was iatrogenic postdural puncture headache. Full relief of the headache was achieved after administration of an epidural blood patch.

Jo, Dae-Jean,Jun, Jae-Kyun,Kim, Sung-Min The Korean Neurosurgical Society 2009 Journal of Korean neurosurgical society Vol.45 No.3

The presence of distant metastases from differentiated thyroid carcinoma decreases the 10-year survival rates of patients by 50%. This is a report of a 61-year-old female with follicular thyroid carcinoma who presented initially with low back pain. 2-deoxy-2-[18F] fluoro-D-glucose whole-body positron emission tomography/computed tomography (PET/CT) demonstrated a hypointensity lesion in the left thyroid gland with malignant uptake in L1 vertebra and magnetic resonance images revealed paravertebral and epidural extension of mass in L1 vertebra. After thyroidectomy, histopathological study showed a follicular carcinoma. We performed L1 total en bloc spondylectomy with expandable cage for long-term local control. The technical details of total en bloc spondylectomy in follicular carcinoma are described herein.

Jo, Dae-Jean,Kim, Ki-Tack,Lee, Sang-Hun,Cho, Myung-Guk,Seo, Eun-Min The Korean Neurosurgical Society 2015 Journal of Korean neurosurgical society Vol.46 No.4

Objective : To present the incidence and management of dural tears and cerebrospinal fluid leakage during corrective osteotomy [Pedicle Subtraction Osteotomy (PSO) or Smith-Petersen Osteotomy (SPO)] for ankylosing spondylitis with kyphotic deformity. Methods : A retrospective study was performed for ankylosing spondylitis patients with fixed sagittal imbalance, who had undergone corrective osteotomy (PSO or SPO) at lumbar level. 87 patients were included in this study. 55 patients underwent PSO, 32 patients underwent SPO. The mean age of the patients at the time of surgery was 41.7 years (21-70 years). Of the 87 patients, 15 patients had intraoperative dural tears. Results : The overall incidence of dural tears was 17.2%. The incidence of dural tears during PSO was 20.0%, SPO was 12.5%. There was significant difference in the incidence of dural tears based on surgical procedures ( PSO vs. SPO) (p<0.05). The dural tears ranged in size from 12 to $221mm^2$. A nine of 15 patients had the relatively small dural tears, underwent direct repair via watertight closure. The remaining 6 patients had the large dural tears, consequently direct repair was impossible. The large dural tears were repaired with an on-lay graft of muscle, fascia or fat harvested from the adjacent operation site. All patients had a successful repair with no patient requiring reoperation for the cerebrospinal fluid leak. Conclusion : The overall incidence of dural tears during PSO or SPO for ankylosing spondylitis with kyphotic deformity was 17.2%. The risk factor of dural tears was complexity of surgery. All dural tears were repaired primarily using direct suture, muscle, fascia or fat graft.

Surgical Experience of Neglected Lower Cervical Spine Fracture in Patient with Ankylosing Spondylitis

Jo, Dae-Jean,Kim, Sung-Min,Kim, Ki-Tack,Sea, Eun-Min The Korean Neurosurgical Society 2010 Journal of Korean neurosurgical society Vol.48 No.1

The management of lower cervical fractures in patients with ankylosing spondylitis (AS) differs from normal cervical fractures. Patients with AS are highly susceptible to extensive neurologic injuries and spinal deformities after cervical fractures from even minor traumatic forces. These injuries are uniquely complex, require careful imaging assessment, and aggressive surgical management to optimize spinal stability and functional outcomes.

Jo, Dae-Jean,Kim, Ki-Tack,Kim, Sung-Min,Lee, Sang-Hun,Cho, Myung-Guk,Seo, Eun-Min The Korean Neurosurgical Society 2016 Journal of Korean neurosurgical society Vol.59 No.2

Objective : To illustrate the technique of single-stage posterior subtotal corpectomy and circumferential reconstruction for the treatment of unstable thoracolumbar burst fractures and to evaluate the radiographical and clinical outcomes of patients treated using this technique. Methods : 16 consecutive patients with unstable thoracolumbar burst fractures were treated with single-stage posterior subtotal corpectomy and circumferential reconstruction. The mean patient age was 54.8 years. The mean follower up period was 25 months. Five patients suffered from T12 fractures, 10 from L1, 1 from L2. The segmental kyphosis, neurologic status, visual analogue scale for back pain was evaluated before surgery and at follow up. Results : The segmental kyphotic angle improved from 18.5 degrees before surgery to -9.2 degrees at the last follow up. The mean correction angle was 28.9 degrees. The mean surgical time was 255 minutes, and a mean intraoperative blood loss was 1073 mL. Intraoperative complications included two dural tears, and a superficial wound infection. There were no other severe complications. The mean visual analog scale of back pain decreased from a mean value of 6.6 to 2 at the last follow up. Conclusion : The single-stage posterior subtotal corpectomy and circumferential reconstruction achieved satisfactory kyphosis correction with direct visualization of the circumferentially decompressed spinal cord, as well as good fusion with less blood loss and complications. It is a safe and reliable surgical treatment option for unstable thoracolumbar burst fractures.
