배기철,Byung-Chan Choi,김두한,연창진,Ji-Hoon Kim 대한정형외과 스포츠의학회 2022 Arthroscopy and Orthopedic Sports Medicine Vol.9 No.2

Background: To compare clinical and radiological outcomes in high tibial osteotomy (HTO) with or without cartilage regeneration surgery using human umbilical cord blood-derived mesenchymal stem cells (hUCB-MSCs) for medial compartment osteoarthritis of the knee. Methods: Patients who underwent HTO only (group H) or HTO with cartilage regeneration surgery using hUCB-MSCs (group HS) were retrospectively reviewed, and these patients had a minimum radiographic and clinical follow-up period of 12 months. The following radiologic parameters were evaluated: hip-knee-ankle angle, tibia plateau inclination, knee joint line orientation, ankle joint line orientation, medial and lateral joint width, and joint line convergence angle. Moreover, the clinical score was evaluated according to the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) and International Knee Documentation Committee (IKDC) scores. Results: A total of 44 knees (group H: 32, group HS: 12) were enrolled. The mean age of group H and group HS were 57.2 and 55.1 respectively. No significant difference in preoperative radiologic parameters and clinical outcomes was observed between the two groups (all P > 0.05). Significant improvements were observed between pre- and postoperative radiologic parameters, except for medial joint width, in both groups. However, these parameters were not significantly different in both groups (all P > 0.05). At the last follow-up, significant improvements were observed in WOMAC and IKDC scores compared with the preoperative score in both groups. However, no differences were observed between the two groups (all P > 0.05). Conclusion: Satisfactory clinical and radiological outcomes were observed in both groups in short-term follow-up. However, no significant difference in clinical and radiological outcomes was observed between the two groups at the last follow-up moment. In the future, a study with medium- to long-term follow-up is needed.

토지의 분할과 합병에 관한 공법적 규율

배기철 행정법이론실무학회 2023 행정법연구 Vol.- No.70

토지를 분할하거나 합병하여 건축물을 건축하는 경우에는 토지의 효율적・합리적 이용을 위해 도시계획적 요소를 고려한 공법적인 규율이 필요하다. 현행 도시계획법제에서는 국토계획법에서 개발행위허가의 대상으로 토지분할을 규정하고, 건축법에서는 건축물이 있는 대지의 분할제한에 관한 규정을 두어, 토지의 분할을 공법적으로 규율하고 있다. 그러나 규율 대상을 특정 지역의 토지분할에 한정하거나 토지분할이 아닌 건축허가의 요건으로 이를 규정하고 있다는 한계가 존재하며, 토지의 합병은 규율 대상에서 제외되어 있다. 실무적으로는 지적을 규율하는 공간정보관리법상 토지의 분할과 합병 절차를 통해 건축단위에 대한 공법적인 규율이 이루어지고 있다. 법령의 개정 연혁과 판례의 흐름을 살펴보면, 초기에는 공유물분할판결 등의 확정판결에 의해 토지소유권이 분리된 경우에는 무조건적으로 토지 분할을 허용하였으나, 기획부동산 등의 폐단으로 인해 관련 규정을 삭제하고 2013년 대법원 판례를 통해 사법상 권리관계에 대해서도 공간정보관리법상 토지 분할 절차를 통한 공법적인 규율이 가능하다는 법리를 제시하였고, 이후 법원은 국토계획법 외에도 건축법, 지방자치단체의 조례 등 토지의 분할 절차에서 고려되어야 하는 공법적 기준을 확대하는 방향으로 판례를 발전시켜 왔다. 건축단위에 대한 규율의 필요성이 증가함에 따라 판례의 법리도 발전한 것으로 평가된다. 다만, 현행 공간정보관리법상 토지의 분할과 합병 절차는 사법적인 규율만을 예정하고 있을 뿐, 건축단위에 대한 공법적 규율을 고려하고 있지 않으며 지적소관청에게 실질 심사권을 인정하고 있지도 않다. 실무적으로는 토지의 분할신청에 선행하여 이루어지는 지적측량 절차를 통해 공법적인 규율이 이루어지고 있으며, 최근 하급심 판례에서는 지적측량 시행규칙에 근거하여 지적소관청의 실질 심사권을 인정한 사례도 확인된다. 그러나 지적측량은 사법상 토지소유권의 권리관계를 확인하기 위한 확인적인 성격만을 가지기 때문에, 지적측량을 통해 건축단위에 대한 공법적 규율이 이루어지는 현행 실무는 근본적으로 지적제도의 체계와는 맞지 않다. 이 글에서는 국토계획법과 공간정보관리법의 관계를 고려한 현행 건축단위의 규율 체계에 대한 개선방안을 제시하였다. 먼저, 공간정보관리법상 토지의 분할과 합병 절차에 있어 지적소관청에게 공법적인 규율이 가능하도록 실질 심사권을 인정하고, 지적측량 절차는 본래의 목적에 따라 토지의 현황과 사실 상태를 확인하는 기능만을 부여하는 방향으로 관련 규정을 개정하여야 한다. 또한, 국토계획법상 개발행위허가(토지분할허가)도 공법적인 규율의 필요성을 고려하여 토지의 합병을 포함한 토지분합허가로 그 대상을 확대하여야 할 것이다. 그러나 공간정보관리법상 토지의 분할과 합병 절차를 통해 건축단위를 규율하더라도 그 효력을 국토계획법상 개발행위허가와 동등한 수준으로 인정하기는 어렵다는 점에서, 종국적으로는 도시계획법제인 국토계획법을 통해 건축단위에 대한 규율이 이루어져야 한다. 이를 위해 현행 규율 체계와 같은 과도기적 과정을 거쳐, 국토계획법상 개발행위허가는 토지형질변경허가를 통해 건축허용성을 규율하고, 토지분합허가를 통해 건축단위를 규율하는 형태로, 건축행위를 규율하기 위한 완결적인 허가 제...

The purpose of this study was to find what are the effects of festival participant's novelty seeking to involvement intention and satisfaction. A survey design was adopted to collect the required information and a random sampling approach was utilized to select the respondents(N=220) at Namwon herb festival. SEM(Structural equation modeling) was used to examine relationship among novelty seeking, involvement intention, and satisfaction. We found the novelty seeking has a positive effect to the involvement intention(standard regression weight=0.375, t=4.120, p<0.01) and to the satisfaction(standard regression weight =0.440, t=5.096, p<0.01). Also, the involvement intention has a positive effect to the satisfaction(standard regression weight=0.267, t=3.397, p<0.01). The findings lead to an improved understanding of the interrelationship among novelty seeking, involvement intention and satisfaction in the context of festival.

The primary objective of this study was to empirically determine the relationship between travel agency images and customer patronages toward five competing travel agencies, and to understand the nature of their competition by matching customer patronage behavior toward alternative travel agencies with perceptions of alternative travel agencies on particular image attribute. This study contributes to the existing consumer patronage behavior literature by providing empirical research results for the interrelationships between multi-store image measures and multi-store loyalty measures. In terms of offering strategic guidelines, this study shows the magnitude of the relationships and explains the nature of competition in a travel market by linking customer patronage behavior toward one or more travel agencies with the image strengths/weaknesses of travel agencies on salient image dimensions. As a consequence, travel agencies can use this information in their repositioning strategies to improve or change their image

Bilateral Medial Tibial Plateau Fracture after Arthroscopic Anterior Cruciate Ligament Reconstruction

배기철,조철현,이경재,전종혁 대한슬관절학회 2015 대한슬관절학회지 Vol.27 No.2

Tibial plateau fractures after arthroscopic anterior cruciate ligament (ACL) reconstruction are rare, and only isolated cases have been reported. The authors describe a case of bilateral medial tibial plateau fracture following a minor motorcycle accident in a patient who underwent arthroscopic ACL reconstruction in the past. Two years and four months before the accident, the patient underwent an arthroscopically assisted ACL reconstruction using double-bundle technique on his left knee at a hospital. He had the same surgery using single-bundle technique on his right knee about eight months ago at another hospital. The fractures in his both involved knees occurred through the tibial tunnel and required open reduction with internal fixation. At three weeks after fixation, a second-look arthroscopy revealed intact ACLs in both knees. At five months follow-up, he was able to walk without instability on physical examination. Follow-up radiographs of the patient showed callus formations with healed fractures.

Effect of Green Tea Extract/Poly-γ-Glutamic Acid Complex in Obese Type 2 Diabetic Mice

배기철,박재형,나안예,김선주,안신병,김상표,오병철,조호찬,김용운,송대규 대한당뇨병학회 2013 Diabetes and Metabolism Journal Vol.37 No.3

Background: The increasing prevalence of type 2 diabetes mellitus (T2DM) is associated with the rapid spread of obesity. Obesity induces insulin resistance, resulting in β-cell dysfunction and thus T2DM. Green tea extract (GTE) has been known to prevent obesity and T2DM, but this effect is still being debated. Our previous results suggested that circulating green tea gallated catechins (GCs) hinders postprandial blood glucose lowering, regardless of reducing glucose and cholesterol absorption when GCs are present in the intestinal lumen. This study aimed to compare the effect of GTE with that of GTE coadministered with poly-γ-glutamic acid (γ-PGA), which is likely to inhibit the intestinal absorption of GCs. Methods: The db/db mice and age-matched nondiabetic mice were provided with normal chow diet containing GTE (1%), γ-PGA (0.1%), or GTE+γ-PGA (1%:0.1%) for 4 weeks. Results: In nondiabetic mice, none of the drugs showed any effects after 4 weeks. In db/db mice, however, weight gain and body fat gain were significantly reduced in the GTE+γ-PGA group compared to nondrug-treated db/db control mice without the corresponding changes in food intake and appetite. Glucose intolerance was also ameliorated in the GTE+γ-PGA group. Histopathological analyses showed that GTE+γ-PGA-treated db/db mice had a significantly reduced incidence of fatty liver and decreased pancreatic islet size. Neither GTE nor γ-PGA treatment showed any significant results. Conclusion: These results suggest that GTE+γ-PGA treatment than GTE or γ-PGA alone may be a useful tool for preventing both obesity and obesity-induced T2DM.

The primary objective of this study was to empirically explore the relationship between supervisory control dimension and performance of travel agency employees. From the empirical research, it was found that the effect of information from supervisor on the performance and satisfaction were more mediated by role ambiguity, working hard than rewards and punishments. Also, high level of knowledge about traveling influenced to performance of travel agency employees. It means that the supervisors of travel agency are needed to manage more effective control like a information serving than rewards and punishments.

IoT 보안 응용을 위한 경량 블록 암호 CLEFIA의 효율적인 하드웨어 구현

배기철,신경욱,Bae, Gi-chur,Shin, Kyung-wook 한국정보통신학회 2016 한국정보통신학회논문지 Vol.20 No.2

경량 블록 암호 알고리즘 CLEFIA의 효율적인 하드웨어 설계에 대하여 기술한다. 설계된 CLEFIA 보안 프로세서는 128/192/256-비트의 세 가지 마스터키 길이를 지원하며, 변형된 GFN(Generalized Feistel Network) 구조를 기반으로 8-비트 데이터 패스로 구현되었다. 라운드키 생성을 위한 중간키 계산용 GFN과 암호 복호 라운드 변환용 GFN을 단일 데이터 프로세싱 블록으로 구현하여 하드웨어 복잡도를 최소화하였다. 본 논문의 GFN 블록은 라운드 변환과 128-비트의 중간 라운드키 계산을 위한 4-브랜치 GFN과 256-비트의 중간 라운드키 계산을 위한 8-브랜치 GFN으로 재구성되어 동작하도록 설계되었다. Verilog HDL로 설계된 CLEFIA 보안 프로세서를 FPGA로 구현하여 정상 동작함을 확인하였다. Vertex5 XC5VSX50T FPGA에서 최대 112 MHz 클록으로 동작 가능하며, 마스터키 길이에 따라 81.5 ~ 60 Mbps의 성능을 갖는 것으로 평가되었다. This paper describes an efficient hardware implementation of lightweight block cipher algorithm CLEFIA. The CLEFIA crypto-processor supports for three master key lengths of 128/192/256-bit, and it is based on the modified generalized Feistel network (GFN). To minimize hardware complexity, a unified processing unit with 8 bits data-path is designed for implementing GFN that computes intermediate keys to be used in round key scheduling, as well as carries out round transformation. The GFN block in our design is reconfigured not only for performing 4-branch GFN used for round transformation and intermediate round key generation of 128-bit, but also for performing 8-branch GFN used for intermediate round key generation of 256-bit. The CLEFIA crypto-processor designed in Verilog HDL was verified by using Virtex5 XC5VSX50T FPGA device. The estimated throughput is 81.5 ~ 60 Mbps with 112 MHz clock frequency.
