Purpose: This study was designed to determine the quantitative changes of the numbers of the mechanoreceptors in the experimentally tenotomized Achilles tendon of rabbits as compared with short-term immobilization and long-term immobilization. Materials and Methods: 14 white rabbits were used. After tenotomizing the right Achilles tendon, the subjects were divided into 2 groups according to the periods of immobilizaton. The left side of each Achilles tendon of the rabbits were used as controls. The tendons were stained with a modified gold-chloride method. Results: The number of mechanoreceptor was significantly decreased in the tenotomized Achilles tendon group than the control group (p<0.01). There was no statistical difference between the two experimental groups in the numbers of the mechanoreceptors (p>0.01). Conclusion: The injured Achilles tendons may more vulnerable to injury because of the decreased numbers of mechanoreceptors, but no difference between the periods of immobilization. It may suggest that post-operative immobilization period may not affect on the outcome of operative treatment from the viewpoint of mechanoreceptors.

Purpose: One of the main contributors to proximal fifth metatarsal fracture is ankle inversion and the incidence of recurrence may increase in patients with ankle instability. So, the authors confirmed the patients of proximal fifth metatarsal fracture with ankle instability by checking the history and magnetic resonance imaging (MRI) and assessed the value of MRI as therapeutic prognosis and clinical indicators for prevention of recurrence. Materials and Methods: Patients with proximal fifth metatarsal fractures visited our hospital during recent five years were reviewed. 35 patients with suspected damage by ankle inversion had been identified a history of ankle instability and checked the hindfoot malalignment through hindfoot alignment view and MRI was performed prospectively. The patients was devided to three groups on the location of fracture site and the groups were compared each other. Results: The mean time from injury to checking MRI was 10.7 days. There was no structural abnormality and was no significant difference according to the location of fracture. The patients with history of ankle inversion were 31(88.6%) and the patients with history of chronic or recurrent injury were 22 patients (62.9%). The lesion of MRI related to lateral ankle instability were identified in all patients. Conclusion: This study noted a high incidence of lateral ankle instability that was identified by MRI in the patients of proximal fifth metatarsal fracture. Aggressive treatment for lateral ankle instability should be needed for complications as proximal fifth metatarsal fracture to reduce the recurrence and occurrence.

We have recently demonstrated the slow release of growth factors from calcium phosphate cements (CPCs) incorporated with platelet concentrate (PC). In the present study, the cell compatibility of CPCs was evaluated by culturing human osteoblast-like cells Saos-2 (ATCC HTB85) to demonstrate the PC effect. CPCs were characterized using scanning electron microscopy (SEM), X-Ray diffraction (XRD) and energy-dispersive X-ray spectroscopy (EDS) and their mechanical properties were tested. The physical and chemical properties of CPCs were little affected by the PC incorporation within the experimented range. The cell proliferation, morphology and migration, measurement of alkaline phosphatase (ALP) levels, mRNA expression for osteopontin (OPG), osteocalcin (OC), glyceraldehyde phosphate dehydrogenase (GAPDH) were evaluated. Higher cell proliferation was performed but the cell migration was not affected by the addition of PC. Actin filaments, focal adhesion, and localized integrin were clearly visible. The PC addition increased ALP activity and expression of GAPDH, OC, and OPG mRNA.

일본에서 환경권론의 전개

유종민(Yoo, Jong-Min),고형곤(Ko, Hyeong-Kon) 전북대학교 법학연구소 2016 法學硏究 Vol.50 No.-

환경권론이 활발하게 주장되게 된 이유는 무엇보다도 환경파괴에 대한 위기의 인식이라할 것이다. 일본에서도 1960년대부터 다양하며 심각한 환경오염문제가 발생하였고, 이러한 환경오염으로부터 발생된 피해에 대하여 司法的 차원에서 피해자를 구제함과 동시에 특히 헌법상의 기본적 인권의 하나로서 또는 私法상의 권리로서 1970년대부터 환경권이라는 새로운 권리가 주장되어 현재에 이르렀다. 그러나 일본에서는 환경권이라는 새로운 권리가 인정되기 시작한 이래 여전히 환경 문제와 관련하여 발생된 피해에 대한 구제가 충분하게 이루어지지 않았다는 지적이 계속되고 있다. 즉, 기존의 배상법제는 환경 문제로 발생된 피해자를 충분하게 보호하고 있지 못하다는 점이다. 또한 최근에는 핵과 방사능 누출 등의 문제로 인하여 환경권론의 중요성에 대해 다시 인식되고 있다. 따라서 본 논문에서는 우선적으로 일본에서 지금까지 논의 되었던 환경권론에 관하여 소개하고자 한다. 아울러 환경권의 배후에 있는 사상으로서 어메니티의 개념에 관하여도 함께 고찰하고자한다. 그 이유는 환경권과 어메니티에 관한 논의를 둘러싼 문제점도 여전히 남아있고 환경권과 어메니티의 개념과의 연관성에 관한 검토도 여전히 필요하기 때문이다. 특히, 국민사이에 공통의 가치관을 뿌리내리게 하는 방향성을 가지고 어메니티에 관한 연구의 부족과 환경권론과 기존의 법리와의 융합이 불충분한 점이 안타까우며 이것을 극복하는 것이 환경권의 확립을 향한 이후의 중요한 과제라고 생각된다. 이에 본 논문에서는 하나의 방향성으로서 환경권이 제창된 경위나 그 바닥에 깔려있는 사상인 ‘어메니티’라는 개념을 재검토할 필요가 있으며, 그 개념을 본격적으로 연구하는 것이 유용하다고 여겨져 일본에서 논의되고 있는 환경권과 어메니티개념에 대해 약간의 검토를 해보고자 한다. The reason why the theory of environmental rights has been actively claimed in Japan is the growing awareness of the crisis stemming from environmental destruction. In Japan, a variety of issues arising from grave environmental pollution have occurred since the 1960s. In addition to relieving the victims from judicial aspect of the damages caused by such environmental pollution, an entirely new right called the environmental rights has been asserted as one of the basic constitutional rights since the 1970s. It has been claimed since the recognition of the new environmental rights in Japan, however, that the damages inflicted in relation to the environmental problems have never been remedied sufficiently up until today. In other words, the existing compensation law does not adequately protect the victims of environmental problems. Recently, the importance of environmental rights has been recognized again in the wake of the series of nuclear and radioactive leaks. Therefore, the author intends to introduce first the concept of environmental rights which has been discussed so far in Japan. In addition, the author will examine the concept of amenity as an underlying ideology behind the environmental rights, the reason being that the problems surrounding the discussion on environmental rights and amenity still remain, and the relevance between the concept of environmental rights and amenity still needs to be reviewed in further detail. What is deplorable, in particular, is the lack of research on amenity as well as the lack of integration between the theory of environmental rights and the existing legal system. We believe that overcoming such challenges would be the most important task that is required to establish the environmental rights in the future. In this paper, therefore, it is necessary to re-review how the environmental right has been claimed in the first place as a distinctive direction as well as the concept of “amenity”, which is the underlying ideology behind the discussions on environmental rights. As the author believes it would be useful to study the concept in earnest, the concept of the environmental rights and amenity that are being discussed in Japan shall be discussed in this paper.

만성 족부 질환이 환측 하지의 골밀도에 미치는 영향

주인탁,유종민,강민구,정진화,Chu, In-Tak,Yoo, Jong-Min,Kang, Min-Gu,Chung, Jin-Wha 대한족부족관절학회 2010 대한족부족관절학회지 Vol.14 No.2

Purpose: Pain or discomfort caused by foot diseases may lead to abnormal gait, resulting in decreased bone mineral density (BMD) of the affected lower limb. We analyzed the effect of foot affection to BMD and its clinical significance. Materials and Methods: Bilateral hip BMD was evaluated in 93 patients with unilateral chronic foot disease. To minimize statistical errors, we excluded patients with medical histories that had influence on BMD. Analysis was based on the results of BMD tests at the first visit. All patients denied past medical intervention for osteoporosis. The difference in density between bilateral limbs was determined by comparing BMDs of the neck, upper neck, trochanter and total area of hip. Results: Test results revealed the decrease of BMD in the lower limb with the affected foot, compared to the unaffected side. This decrease was significant in the area of the trochanter (p <0.05). There was no marked difference of BMD in relation with duration of affection, underlying disease or age. Pertaining the location of foot affection, the hindfoot group showed significant decrease in BMD compared to the forefoot group. The group with affection in bone and joint also showed a marked decrease in BMD compared to the soft tissue group (p <0.05). Conclusion: Pain and discomfort caused by chronic foot diseases can lead to a decrease in the BMD of the affected lower limb. This may increase the risk of complications such as osteoporotic fracture and muscular atrophy.

Purpose: This study was designed to evaluate the clinical and radiographical results of anatomical reconstruction by Chen method for chronic lateral ankle instability. Materials and Methods: Fifteen patients with chronic lateral ankle instability who had undergone anatomical reconstruction of anterior talofibular and calcaneofibular ligaments by Chen method were evaluated retrospectively. Average age of the patients was 31.3 years, and average follow-up period was 15.5 months. Preoperative and postoperative radiographs including varus stress view and magnetic resonance imaging (MRI) were analyzed. The clinical evaluation was performed according to the American Orthopaedic Foot and Ankle Society (AOFAS) scale. Results: Radiographically average talar tilt angle was $15.3^{\circ}$ preoperatively, and the difference with contralateral normal side was $10.1^{\circ}$. At last follow up, talar tile angle and the difference with contralateral side improved to $5.9^{\circ}$ and $1.3^{\circ}$ respectively. AOFAS scale was 66.6 preoperatively and 87.3 postoperatively. In MRI findings, four patients had associated intra-articular lesion such as articular cartilage defect, synovitis and osteoarthritis. The talar tilt angle improvement and AOFAS scale of patients without intra-articular lesion was better than those of four patients with intra-articular lesions. Surgical wound pain occurred in six patients and sural neuropathy in three patients. Conclusion: The anatomical reconstruction by Chen method was an easy and effective procedure for symptomatic chronic lateral ankle instability. Careful operative technique may prevent the surgical wound pain and sural neuropathy.

Purpose: The aim of this study was to evaluate the result of combined first metatarsal and calcaneal osteotomy for static cavovarus deformity of the foot. Materials and Methods: We performed a dorsal closing wedge $1^{st}$ metatarsal osteotomy and a lateral and upward displacement calcaneal osteotomy for 9 patients, 12 feet (6 male and 3 female). The mean age at the time of operation was 37 years and the mean followup period was 27 months. The causes of deformity were 2 poliomyelitis, 1 cerebral palsy, 1 Charcot-Marie-Tooth disease and 5 idiopathic type. Five lateral ligament reconstructions of the ankle and six percutaneous Achilles tendon lengthenings were added. The surgical results in terms of pain, function and alignment of the foot were evaluated by means of AOFAS ankle-hindfoot score and talo-$1^{st}$ metatarsal, calcaneus-$1^{st}$ metatarsal and calcaneal pitch angles were checked with weight bearing radiographs in lateral projection. Results: Talo-$1^{st}$ metatarsal and calcaneal pitch angles were reduced from the mean preoperative values of $21^{\circ}$ and $25^{\circ}$ to $12^{\circ}$ and $19^{\circ}$, respectively, at last followup. Also, calcaneus-$1^{st}$ metatarsal angle was increased from the mean $114^{\circ}$ to $114^{\circ}$. The mean AOFAS score was improved from 44.5 points preoperatively to 89.2 points at followup. There were 1 metatarso-cueiform joint nonunion, 1 sural nerve injury and 3 remaining symptomatic claw toes. Conclusion: Combined first metatarsal and calcaneal osteotomy appears to be an effective procedure for the treatment of adult static cavovarus foot.

학생에 대한 징계규정의 인권적 고찰

정영선(Chung, Young-Sun),유종민(Yoo, Jong-Min) 전북대학교 법학연구소 2013 法學硏究 Vol.40 No.-

오늘날 우리사회에서의 인권의식은 전반적으로 향상되고, 학생인권조례로 대표되듯이 학생인권에 대한 인식도 상당부분 향상되고 있다. 그럼에도 불구하고 학교현장에서는 표면적으로 인권교육의 중요성을 이야기 하면서도, 실제적으로는 교육목적을 수호하기 위한 교육활동의 일환인 징계로 인한 학생인권이 침해되는 경우가 여전히 발생하고 있다. 물론 학교에서 적법절차에 따라 인권적이며 교육적인 징계를 행할 수 있다는 것에 대하여는 반론이 있을 수 없다. 하지만 이때의 징계는 교육상 필요한 경우에 한하여 적법절차에 따라 행해지는 경우에만 허용되어야 하고, 이러한 경우에도 반드시 교육적 배려가 요구된다. 그러나 여전히 학교에서는 다양한 형태로 이루어지는 생활지도(징계 또는 체벌)와 관련하여 다양한 문제가 발생하고 있다. 이러한 이유 중 하나는 학교현장에서 적법절차에 따른 제도적 징계는 무시되고 보다 손쉬운 사실상 징계인 체벌이 암암리에 행해지고 있기 때문이다. 결국 적법하고 합리적인 제도적 징계가 적절한 생활지도로서 행해져야 함에도 불구하고 위법하고 부당한 체벌이 행해짐으로써 결과적으로 학생 지도에는 역효과를 가져오게 된다. 이상의 관점을 기반으로 하여 본 논문에서는 학생에 대한 징계 관련 규범과 실제 발생하는 체벌 간에 괴리가 있음을 착안하고, 징계는 적법한 제도적 징계에 한정되어야 함을 논증 하였다. 이 문제와 관련하여 일본은 가정에서 뿐만 아니라 학교에서도 학생의 인권을 보호하기 위하여 체벌을 금지하는 방향으로 민법과 학교교육법을 개정하였는데, 이러한 시도는 우리나라의 법령개정 방향에 시사하는 바가 크다. 따라서 학생 징계와 관련하여 우리나라와 일본의 관련 법률 및 규칙 등을 비교함으로써 우리의 학생지도 방법이 나아갈 방향에 대하여 논하였다. 이와 아울러 적법절차의 준수여부와 관련하여 사실상 징계인 체벌의 문제점 및 반인권적 성격을 분석하였으며, 이를 토대로 학생 징계 및 지도의 인권적 방향을 제시하고자 하였다. Human rights sensitivity of people‘s is increasing day by day, as we can see that the establishment of human rights ordinances for students plays a key role for improvement of human rights of students. On the one hand, people apparently talk about the importance of human rights in school, on the other hand, a lot of cases on human rights violation against students have been reported, specially with a disguised education with two faces. It is no wonder that legal punishment based on the due process is inevitable in some sense, however, such a punishment can be understood only in case which is considered as a reasonable mean for goal of good education itself. More seriously, the corporal punishment under the name of effective education can not be permitted in any condition. The legal and reasonable punishment can only be considered as the appropriate means for education of student, however, the corporal punishment(as de facto punishment) is still alive and negatively impact on the student guidance regulations. In this respect, this paper is carrying out analysis on the illegal characteristics of the corporal punishment and arguing that it can not be the right solution for student education. Based on the comparative study on the civil laws between Korea and Japan, it is impressed that Japan even removed the potential article on the corporal punishment in its amendment of civil law in 2011. Through the comparative legal studies, this paper makes a conclusion that Korean laws are needed to amend the plausible parts on the corporal punishment, as well as it leads the potential direction for student guidance with human rights-based approach.

이승구,강용구,서유준,유종민,정인호,Rhee, Seung-Koo,Kang, Yong-Koo,Suh, Yoo-Joon,Yoo, Jong-Min,Jung, In-Ho 대한근골격종양학회 2004 대한골관절종양학회지 Vol.10 No.2

목적: 악성 골, 연부 조직 종양 환자에게 시행한 자가골 재이식술을 이용한 사지 구제술의 치료 결과를 분석하여 그 유용성을 알아보고자 하였다. 대상 및 방법: 1990년 2월부터 2003년 1월까지 악성 골, 연부 조직 종양으로 자가골 재이식술을 이용한 사지 구제술을 시행 받은 환자 중에서 최소 18개월 이상 장기 추시가 가능했던 29예를 대상으로 하였다. 남자가 18예, 여자가 11예로 환자의 평균 연령은 33세(범위, 10~65세)였고, 평균 추시 기간은 51.8개월(범위, 18~117개월)이었으며 Enneking의 분류에 따른 병기는 IIA가 10예, IIB가 19예였다. 자가골의 재처리 방법은 동결 처리법(deep freezing)이 6예, 고온-고압 처리법(autoclaving) 11예, 저온 처리법(pasteurization이) 7예였으며, 5예 에서는 고온-고압 처리법과 혈관 부착 비골 이식술을 병행하였다. 단순 방사선 검사를 통하여 골 유합을 평가하였고, 1993년에 국제 사지 보존 회의(International Symposium On Limb Salvage; ISOLS)에서 수정 보완한 방법을 이용하여 기능을 평가하였다. 결과: 골 유합 기간은 평균 7.2개월(범위, 3~15개월)로, 동결 처리법은 5.8개월(범위, 4~8개월), 고온-고압 처리법은 9.7개월(범위, 6~15개월), 저온 처리법은 5.9개월(범위, 4~8개월)이었고, 고온-고압 처리법과 혈관 부착 비골 이식술을 병행한 경우는 5개월(범위, 3~7개월)이었다. 기능 평가 백분율은 평균 76.8% (범위, 40~90%)로, 동결 처리법은 65.8% (범위, 40~85%), 고온-고압 처리법은 76.6%(범위, 40~90%), 저온 처리법은 81.6%(범위, 70~90%)였고, 고온-고압 처리법과 혈관 부착 비골 이식술을 병행한 경우는 83.4%(범위, 75~90%)였다. 6예에서 합병증이 발생하였는데 국소 재발, 폐 전이, 감염, 골절이 각각 1예였고, 절골부의 불유합이 2예였다. 결론: 자가골 재이식술을 이용한 사지 구제술은 악성 골, 연부 조직 종양의 유용한 치료 방법이며, 특히 고온-고압 처리법을 이용한 자가골 재이식술은 국소 재발을 방지할 수 있는 확실한 방법이었으며, 혈관 부착 비골 이식술을 병행하면 재처리된 자가골의 기계적 강도나 골유도 능력이 감소하는 단점을 보완할 수 있을 것으로 판단된다. Purpose: To determine the usefulness of limb salvage operation with recycled autogenous bone graft in musculoskeletal malignant tumors. Materials and Methods: Twenty nine cases, who underwent limb salvage operation with recycled autogenous bone graft for the treatment of musculoskeletal malignant tumor between February 1990 and January 2003, were included. There were 18 males and 11 females and the mean age was 33 years (range, 10 to 65 years). The mean follow-up period was 51.8 months (range, 18 to 117 months). The Enneking stage was IIA in 10 cases and IIB in 19 cases. The recycling method of autogenous bone was deep freezing in 6 cases, autoclaving in 11 cases, pasteurization in 7 cases and the composite of autoclaving and vascularized fibular graft in 5 cases. The union of junctional site was evaluated radiologically and the functional results was analyzed by the grading systems of the International Symposium On Limb Salvages (ISOLS). Results: The mean union time was 7.2 months (range, 3 to 15 months). The union took 5.8 months (range, 4 to 8 months) in deep freezing, 9.7 months (range, 6 to 15 months) in autoclaving, 5.9 months (range, 4 to 8 months) in pasteurization, and 5 months (range, 4 to 8 months) in the composite of autoclaving and vascularized fibular graft. The mean functional evaluation percentage was 76.8% (range, 40 to 90%). It was 65.8% (range, 40 to 85%) in deep freezing, 76.6% (range, 40 to 90%) in autoclaving, 81.6% (range, 70 to 90%) in pasteurization, and 83.4% (range, 75 to 90%) in the composite of autoclaving and vascularized fibular graft. There were 6 cases of complications including 1 case of local recurrence, lung metastasis, infection, fracture, respectively and 2 cases of nonunion. Conclusion: The limb salvage operation with recycled autogenous bone graft is a useful treatment method for the musculoskeletal malignant tumors. Particularly, autoclaving is the most reliable sterilization method. The vascularized fibular graft can compensate decreased osteoinductivity and mechanical strength of recycled bone. So, the composite of autoclaving and vascularized bone graft seems to be a favorable treatment method for high grade malignant musculoskeletal tumors.
