현재 대한민국은 물류산업을 이끌어갈 물류전문 컨설턴트가 절실히 필요하다. 글로벌 물류시대를 맞이하여 물류기업뿐만 아니라 각 제조업체도 물류전문가, 특히 글로벌 물류인재에 목말라 하고 있다. (사)한국물류협회(회장:서병륜)는 지난 6월 17일 협회 대강당에서 제2기 물류전문컨설턴트 29명을 배출하면서, 기업체들의 전문인력의 갈증에 조금이나마 해소하고 있다. 명지대학교와 산학협력 프로그램으로 실시되는 물류전문컨설턴트 양성과정은 물류분야 최고의 컨설턴트와 전문 교수진으로 구성하여, 회사 및 업계에서 물류컨설턴트로 활동할 물류지도자를 양성하는 자격 과정이다. 지난해 9월부터 시작한 이 과정은 우수한 강사진과 커리큘럼으로 국내기업으로부터 지대한 관심을 받으며 제1기 과정과 제2기 과정을 성공적으로 마쳤다. 한편, 오는 9월에 실시되는 제3기 과정에는 모집공고가 나오기도 전에 사전신청자가 11명에 이를 정도로 지원자가 급증하고 있다. 이는 교육 과정이 물류 전문가라면 알아야 될 내용들로 짜임새 있게 구성되어 있지만 더욱 중요한 것은 물류업계 전문가들과 인적 Network 구축이 큰 메리트로 작용하고 있다. 제2기 과정을 수료한 LG화학의 오태경부장은 "지금까지 수 많은 교육을 받아 봤고 여러 종류의 모임에도 참여해 봤지만 과거에는 경험해 보지 못한 전혀 색다른 교육 과정을 체험을 하였다."고 말했다.

Purpose: The purpose of this study is to evaluate the clinical usefulness of ultrasound in treatment of patella fracture. Material and Methods: Twenty cases of twenty patients with patella fracture radiographically from March, 2006 to September, 2009 were involved in this study, there were 8 males and 12 females, there were 13 right knees, 7 left knees, the average age was 43 years (range, 14~72 years). We decided the methods of treatment by using the ultrasound in conjunction with Drayer's test that examining the intactness of patella retinaculum. There were 10 transverse, 8 vertical and 2 comminuted fractures, we examined the patella retinaculum by using the ultrasound and performed Drayer's test. Results: In 12 cases of intact retinaculum, Drayer's test was negative and we allowed patients ambulation without surgical fixation especially. In 4 cases of completely ruptured retinaculum, Drayer's test was positive and we treated the patella fractures by the use of ORIF (open reduction and internal fixation) method, in 2 cases of partially ruptured retinaculum, Drayer's test was negative but displacement of fractures were more than 2 mm, we treated the patella fractures by the use of CRIF (closed reduction and internal fixation) method and obtained clinically satisfactory results. Conclusion: In conjunction with radiographs and Drayer's test, an ultrasound would be one of the useful diagnostic modality for determining treatment method of the patella fracture.

This study aimed to explore the constructs of the characteristics of at-risk learners with diverse educational needs in the blind spots of education, in order to understand them comprehensively and detect them early in schools. Participants were 156 elementary, middle, and high school teachers who filled out a semi-structured questionnaire consisting of open questions about their implicit knowledge of the characteristics of at-risk learners in the blind spots of education. Qualitative data were analyzed using a modified consensual qualitative research method. The main findings of this study are as follows. First, five domains and 16 categories were derived as the main constructs of the characteristics of learners in the blind spots of education. Second, the most listed of the five domains was the "domain of low learning and cognition," whereas the least listed domain was the "everyday life domain." Finally, deficiencies of interpersonal skills and interactive communications and categories related to family structure and functions frequently appeared among the 16 categories. Based on these results, implications and potentials for follow-up studies were further discussed.

Purpose: Implant surface modification and implant design are the principle targets for achieving successful primary stability. The aim of this study was to measure implant stability quotient (ISQ) values of sandblasted, large-grit, acid-etched (SLA) implants with tapered straight body design during the healing period, and to determine the various factors affecting implant stability. Materials and Methods: To measure implant stability, resonance frequency analysis (RFA) was performed in 26 patients (13 women and 13 men) with 44 SLA implants with tapered straight body design. Implant stability (ISQ values) was evaluated at baseline and healing abutment connection (12 weeks), and the correlations between RFA and insertion torque (IT), bone quality, and jawbone were determined. Results: The mean ISQ value of the implants was $69.4{\pm}10.2$ at the time of implant placement (baseline) and $81.4{\pm}6.9$ at the time of healing abutment connection (P < 0.05). Significant differences were found between RFA and bone quality and between RFA and jawbone (P < 0.05). No significant differences were found between RFA and IT, insertion area, fixture diameter, and implant length (P > 0.05). Conclusion: ISQ values of SLA implants with tapered straight body design were high at baseline and healing abutment connection. It was concluded that SLA implants with tapered straight body design show improved primary and secondary stability, and that immediate or early loading may be applicable.

Purpose: The purpose of this study is to evaluate the clinical results of posterior cruciate ligament (PCL) and posterolateral structure (PLS) reconstruction using bilateral hamstring tendon autografts. Materials and Methods: From October 2002 to March 2004, ten patients were received PCL and PLS reconstruction simultaneously using bilateral hamstring autografts. PCL was reconstructed using ipsilateral hamstring tendon and fixed with cross pins and Intrafix (Mitek, Norwood, MA). PLS was reconstructed using contralateral hamstring tendon. The mean follow up was 17 months. Clinical assessments consisted of Lysholm knee scores, International Knee Documentation Committee (IKDC) evaluation form and posterior stress radiographs. External rotation of tibia was evaluated at $30^{\circ}\;and\;90^{\circ}$ knee flexion using Noyes and Barber-Westin's classification. Contralateral harvest site morbity was evaluated using IKDC evaluation form and flexion power of the knee. Results: Mean posterior displacement of tibia using stress radiographs was improved from 13.3 mm to 3.7 mm. In tibial external rotation evaluation, 7 patients were functional, 2 patients were partially functional and one failure. The average Lysholm knee score improved from 54 preoperatively to 86 postoperatively. At the final IKDC evaluation, 8 patients were graded as nearly normal, 2 were graded as abnormal. In contralateral harvest site morbidity evaluation, 2 patients complained of numbness around the wound but negligible. Conclusion: PCL and PLS reconstruction using bilateral hamstring autografts was considered as a good treatment method with minimal contralateral harvest site morbidity.

Purpose: The purpose of this study was to investigate the effect of implant connection type on marginal bone loss (MBL) and to analyze the factors that affect MBL. This study focuses on single implants planted in the upper and lower first molar area. Materials and Methods: A total of 87 implants from 68 patients were tracked for a period over 5 years. There were 57 external connection type (EC) implants and 30 internal connection type (IC) implants in 38 males and 30 females. The MBL and EA were measured from intraoral radiograph images taken after 5 years at most. Results: Significant difference in MBL between EC and IC type was observed in patients without GBR or diabetes. Patients without GBR exhibited an MBL of -0.065 ± 0.859 mm in EC type and -0.627 ± 0.639 mm in IC type (P = 0.025). Using multiple regression analysis, a statistically significant negative correlation was observed between MBL and conditions including implant-abutment connection type (β = -0.303), diabetes (β = -0.113), emergence angle > 30° (β = -0.234), and age (β = -0.776). Conclusion: Within this results, IC type implants had less MBL than EC type, and implant prosthesis with emergence angle over 30° showed greater MBL. To minimize the MBL of the implant and ensure implant stability, careful consideration should be given to the EA of implant prosthesis and its connection type.

Purpose: The purpose of this study was to evaluate the 3 dimensional accuracy of impression taking on the newly developed healing abutment and impression coping combined system comparing conventional pick-up type impression. Materials and methods: For 10 patients who had a single missing tooth on molar area, dental implants (SuperLine; Dentium, Seoul, Korea) were placed and healing abutment (MyHealing; Raphabio Co., Seoul, Korea) abutments were connected. After 3 months, transfer type impression with MyHealing and pick-up type impression with impression coping were performed twice in the same patients, and master models were fabricated. Customized prosthetic abutments (Myplant; Raphabio Co., Seoul, Korea) were milled and connected to the master casts. Through a dental scanner (Scanner S600; Zirkonzahn, South Tyrol, Italy), the master casts were converted into virtual casts. The length and angulation differences between casts were measured using 3 dimentional analysis program (Geomagic Qualify 12; Geomagic, Morrisville, NC, USA). Statistical significance was calculated using Kruskal Wallis test and Mann-Whitney U test (${\alpha}$=.05). Results: The length differences between the two systems were 0.032 mm in sagittal plane, and 0.029 in coronal plane, and 0.023 mm in horizontal plane. The angulation differences were $0.755^{\circ}$ in sagittal plane, and $1.275^{\circ}$ in coronal plane, and $0.420^{\circ}$ in horizontal plane. Conclusion: The accuracy of newly developed healing abutment system is similar to that of conventional pick-up impression. The new system can reduces chair time by not using separate impression coping.

Student records are essential for the functional, social, and personal aspects of the university. However, it is difficult to systematically manage such records because of the vast amount produced by several agents, the decentralization of the university's records management system, and various types and forms produced. Despite acknowledging the importance of student records, Myongji University implements its records management system at a sluggish pace. This study defined students' records except for the administrative records of the university as "student-related records" and categorized them into education records, student creation and research records, and student activity records. After examining the best practices in Korea and abroad, we reviewed the current status of Myongji University's student records management system and proposed appropriate and comprehensive management plans accordingly.
