청소년의 자원봉사 활동 기간이 사회적 책임성에 미치는 영향 : 자원봉사활동 만족도의 매개효과를 중심으로
심정수,문재우 한국통합사례관리학회 2014 한국케어매니지먼트연구 Vol.13 No.-
지속적인 자원 봉사가 청소년의 사회적 책임성에 미치는 영향을 규명하여 청소년으로 하여금 1회성 자원봉사 보다는 장기적이고 지속적인 자원봉사를 지향하도록 하는데 필요한 기초자료를 제공하는 데 본 연구의 목적이 있다. 본 연구는 경기도에 거주하는 중학교 1학년에서 고등학교 3학년까지의 청소년을 대상으로 2012년 8월 1일에서 8월 31일 사이에 실시하였으며, 설문지는 총 390부를 배부하여 363부를 수거하였다. 그 중 부적합한 무응답 설문지 및 불성실하게 응답한 설문지를 제외하고 최종 346부를 조사 분석에 사용하였다. 자료처리는 SPSS 18.0 통계패키지를 이용하였고, 변인간의 인과관계 검증을 위한 구조방정식모형은 AMOS 21.0을 이용하여 분석하였다. 연구결과 자원봉사 활동 기간은 자원봉사 활동 만족도에 영향을 미치는 것으로 나타난 반면 활동기간의사회적 책임성은 유의하지 않았다. 또한 자원봉사 활동 만족도는 자원봉사활동 기간과 사회적 책임 간에매개역할을 하는 것으로 조사되었다. 따라서 청소년의 사회적 책임감을 제고시키기 위해서는 자원봉사활동만족도를 높이고, 이를 위해서는 자원봉사활동을 지속할 수 있는 프로그램의 개발과 실천이 중요하다. The purpose of this study was to provide basic data for long-term sustainable volunteer ratherthan a one-time volunteer by investigating the effect of adolescents’ volunteer on socialresponsibility. In this study, 390 students of middle school and high school living in Gyeonggi-do wereinterviewed by using questionnaires from August 1 to August 31 in 2012 and 363 students werecollected. Among them 346 cases were used in the final research. For data processing the SPSS18.0 statistical package was used and AMOS 21.0. was used for a causal relationship between thevariables. As the results of this study, volunteering period was shown to affect volunteer satisfaction,whereas not to affect social responsibility significantly. Also volunteer satisfaction acted as anintermediary between volunteering period and the social responsibilityTherefore, in order to enhance youth's social responsibility it is important to enhance volunteersatisfaction, and to develop sustainable volunteering program.

Adipose derived stem cells (ASCs) are multipotent cells capable of forming bone, cartilage, and other connective tissues. We focused our attention on ASCs with myogenic potential which might be a useful function of stem cell-mediated tissue engineering in various clinical situations related with muscular defects. ASCs could be easily harvested from enzymatic digestion of human adipose tissue and readily culture expanded in vitro. Prior to seeding the cells onto the porous hyaluronic acid-collagen matrix scaffolds of 8 mm diameter and 0.5mm thickness, the cells were labeled with Feridex®. In 12 Sprague-Dawley rats, through mid-abdominal incisions, anterior sheath of rectus abdominis muscle was opened and a circular muscle defect was made within rectus abdominis muscle. ASCs-seeded scaffold discs were then placed within muscular defects in experimental group (n=6). In control group, scaffold discs without stem cells were implanted into muscular defects (n=6). Six weeks after implantation, the recipients were sacrificed and the tissue engineered constructs harvested. In Prussian blue stain, the specimens of experimental group displayed numerous myoblasts and abundant blood vessels containing labeled Feridex® particles of dark blue color within cytoplasm. In conclusion, the present results indicate that hyaluronic acid-collagen matrix scaffold is an effective material for muscular and ASCs can be differentiated into myocyte within the scaffold and the cells also provoke neovascularization. Further studies utilizing dynamic modalities in vitro and in vivo might be necessary for the refinement of muscular tissue engineering.

Mandibular anterior segmental osteotomy, is an alternative surgery for patients with pseudoprognathism who do not tolerate orthodontic treatment. When genioplasty is required as a concomitant procedure, this is easily accomplished without the deformation of occlusion by leaving a horizontal bony bar. However, for patients with a short chin, there is no space to leave a bony bar. Hence, a complete osteotomy is required to separate the mandible into several pieces, which include anterior dentoalveolar segment, mentum and two mandibular bodies, leaving no structural continuity of the mandible. In this case, it is essential to consider the occlusion, to use a wafer splint, and to proceed with a long duration of intermaxillary fixation. The authors describe a modified procedure from the one described above for mild pseudoprognathism and a short chin. An 18-year-old female was concerned about her asymmetric lower facial appearance and anterior cross-bite with protruding short chin. After mandibular anterior segmental osteotomy and setback reposition, we made an angulated bony bar. Another horizontal osteotomy was performed 2mm apart from the previous osteotomy line and angulated 30 degree leaving about 8mm on the posterior cortex. The movable chin segment was repositioned posteriorly and fixed to the bony bar using two 11-mm screws. The long-term result was satisfactory both functionally and aesthetically.

The coverage of soft tissue defects around the knee joint or upper one third of lower leg presents a difficult challenge to the reconstructive surgeon. Various reconstructive choices are available depending on the location, size and depth of the defect. The authors present their clinical application of a medial sural artery perforator island flap as a useful alternative method for upper one third of lower leg and knee reconstruction. From 2002 to 2004, we operated total 4 patients (total 4 flaps) using the medial sural artey perforator island flap for coverage of the defect on upper one third of lower leg and knee, of 4 patients, 3 patients was men and one was woman. Average patient age was 54.6 years. The largest flap obtained was 10×8cm2. Postoperative follow up of the patients ranged from two to 33 months. In two cases, defects was located on upper one third of lower leg and in other two cases, defects were on the knee. All four cases had bone exposure open wound. In angiography, 2 cases had injured in the anterior tibial artery, 1 case had injured in the posterior tibial artery. There were no diabetes or other vascular disease. All 4 flaps were survived completely, without minor complications such as venous congestion and hematoma. Donor morbidity was restricted substantially to the donor linear scar. There were no functional impairment. As the main advantages of the medial sural perforator island flap, it ensures constant location and reliable blood supply without sacrificing any main source artery or damaging underlying muscle. This procedure is valuable extension of local flap for defect coverage with minimal functional deficit donor site and good aesthetic result on the defect.We consider it as one of the useful methods of the upper one third of lower leg and knee reconstruction.
