The surgery of oral and maxillofacial area poses the risk of cranial nerve damage such as trigeminal nerve or facial nerve. Inferior alveolar nerve is prone to damage in the third molar extraction, implant installation, orthognathic surgery, open reduction and rigid fixation, and tumor ablation surgery. On the other hands,facial nerve is likely to be damaged or sacrificed with trauma or parotidectomy. In case of inferior alveolar nerve injury, the incidence is reported to be about 1.3%. The nerve function will almost recover in minimal damage, but it won't recover at last in total damage of a part of nerve unit. In latter cases, nerve regeneration in intended by allograft as nerve substitute or various route of merve condit. But the recovery with autograft is believed to be most relialbe mrthod in the rapair of long-span(longer than 15㎜)nerve defect. We have performed autologous sural nerve graft in the repair of nerve defect, which is caused by resection of benign or malignant tumor. Hereby we report the method of nerve harvesting, recovery of defected peripheral nerve and the complications of donor site with the discussion of sural nerve anatomy.

홍정은,이재원 용인대학교 2011 특수체육연구 Vol.9 No.-

본 연구의 목적은 특수체육교육전공 대학생의 교육적 신념과 가치정향을 알아보는 것이다. 연구 목적을 달성하기 위하여 특수체육교사양성과정에 있는 대학생 345명을 연구대상으로 설문지를 사용하여 자료를 수집하였고 SPSS Ver 18.0 통계 프로그램을 사용하여 분석하였다. 자료 분석결과를 기초로 하여 도출된 연구의 결론은 다음과 같다. 첫째, 특수체육교육전공 대학생의 교육적 신념의 경향은 성숙주의-행동주의-상호작용주의 순으로 나타났다. 이는 환경적인 요인 보다는 생리적, 유전적 요인에 의한 것이 훨씬 더 크게 작용한다고 볼 수 있다. 둘째, 개인적 특성에 따른 특수체육교육전공 대학생의 가치정향의 차이를 최우선 순위에 대한 빈도를 중심으로 살펴보았을 때 자아실현-생태통합-사회책임-학습과정-내용숙달 순으로 나타났다. 개인적 특성에 따라 살펴보면 성별, 가족 중 장애인 유무, 학년, 통합체육수업을 최초로 경험한 시기나 유무, 통합체육수업을 경험한 기간, 통합체육수업의 경험 유무에 상관없이 자아실현을 최우선 가치로 생각하고 있으나 차선 가치에서는 차이를 보였다. 이상의 결론을 종합하여 볼 때, 초․중․고등학교의 장기적인 통합교육경험이 교육적 신념에 가장 큰 영향을 끼치는 것으로 나타났고, 통합체육수업의 경험이 길수록 교육신념이 높음을 검증하였다. 또한 특수체육교육전공 대학생의 개인적 특성에 상관없이 자아실현을 최우선 가치로 생각하고 있으나 차선 가치에서는 차이를 보였다. 연구의 제언점으로 가치정향 연구의 문항군별 최우선 가치 중심의 최우선 순위 빈도는 선행 연구와의 분석 방법의 차이로 비교가 불가능하며, 질적 연구를 활용한 다양한 연구방법이 추가 되어야 할 것이다. The purpose of this study was to examine the educational beliefs and value orientation of special physical education majors. The subjects in this study were 345 college students who took courses to become special physical education teachers. After a survey was conducted to gather data, the collected data were analyzed by the statistical package SPSS 18.0. The findings of the study were as follows: First, as for a pervasive trend in the educational beliefs of the special physical education majors, maturationism was most dominant, followed by behaviorism and interactionism. It could be said to indicate that they were far more affected by their physiological and hereditary factors than by environmental ones. Second, when the priorities of the value orientation of the special physical education majors were checked in consideration of their personal characteristics, they gave top priority to self-realization, followed by ecological integration, social responsibility, leaning process and disciplinary mastery. By personal characteristics, they placed the most significance in self-realization regardless of gender, the presence or absence of a disabled person in their families, the first time to take an inclusive P.E. class, experiences of taking an inclusive P.E. class and the period of receiving inclusive P.E. instruction. But there were differences among them in the second most important value according to the personal characteristics. The above-mentioned findings illustrated that long-term educational experiences in elementary and secondary schools had the largest impact on educational beliefs, and that they had better educational beliefs when they had more experiences to receive inclusive P.E. instruction. The special physical education majors gave top priority to self-realization irrespective of their personal characteristics, but there were differences among them in the second most important value.

Schwann cells(SCs), an important component of the peripheral nervous system, intract with nerous to mutually support growth and replication for the peripheral nerve regentation. Recently, ading SCs to the lumen of guidance channel is widely tried to improve regeneration or to make regeneration possible over otherwise irreparable gaps. however, it is not easy to isolate and multiplicate SCs as much as enough to help the axonal regeneration. For the allogeneic SCs source for tubular nerve guidance, we developed a little bit improved technique of harvesting and multiplicating SCs. by culturing dispersed dorsal root ganglia in specially designed medium with growth factors and serial processing, we repeatedlly generate relatively homogenous SC cultures. Our technique was compared with other methods of literature using immunostaining methods such as GFAP, S100, BDNF and the total SC count assessment at different time interval after primary culture.

우수방사성의약품 생산시설 개발

신병철,정원명,박상현,이규일,박경배,박진호 한국약제학회 2003 Journal of Pharmaceutical Investigation Vol.33 No.2

Manufacturing facilities of the pharmaceuticals must meet certain level of the cleanness required so that foreign substances such as dust, moisture, heat, microorganism, or virus do not contaminate the product. In case of radiopharmaceuticals for medical treatment and diagnosis, not only should the operators and environment be protected from radiation but also need to be isolated from the foreign contaminant. Therefore, manufacturing facilities for radiopharmaceuticals must satisfy the design standards of both hot cell and clean room which are specified by GNP. However, standards of maintaining negative pressure for preventing spread of radioactive contaminant in isolated facilities conflict with the standards of maintaining positive pressure for keeping cleanness. To solve this problem, are pressure of hot cell was designed lower than in the adjacent area to meet standards of the radiation safety. To keep higher cleanness in certain part of the hot cell for filling, minimal relative positive pressure allows. In order to effectively maintain the cleanness that is required for production of Tc-99m generator, which takes 70% of whole demand of radiopharmaceuticals, the rooms placed in each side of production room are used as a buffer area and three lead hot cells are installed in production room. In this research, we established the appropriate engineered design concept for Tc-99m generator manufacturing facility, which satisfies both GMP cleanness standard for preventing particles, bacteria, other contaminants and the regulations of radiation safety for supervising and controlling the amount of radiation exposure and exhausted radioactivity. And the concept of multi-buffer zones is introduced to apply negative air pressure for hot cell with first priority and to continue relative positive air pressure for clean room.

A Study of Psychotherapy Plan through Game Graphics Focused on Color Preference of Children

Choung-Hun Lee,Su-Hyun Jin,Won-Hyung Lee 보안공학연구지원센터 2016 International Journal of u- and e- Service, Scienc Vol.9 No.7

Colors are recognized by human vision or visual organ. In particular, many studies show that these colors have been proved to give great influences on cognitive development and emotional formation of children. The subconsciousness of children is detectable by colors and through this, their inner emotions and subconsciousness can be revealed. Children have higher interaction of emotion and feelings with colors than adults. Moreover, children tend to express their subconsciousness through colors. However, children are defenselessly exposed to colors coming from the IT devices due to the broad diffusion of these appliances. Different types of media materials give impact on the emotions and cognitive development of children. Likewise, the colors represented by media materials considerably exert influence on the emotions and cognitive development of children. With this in mind, this study proposes design game graphics through analysis of colors, composition, nature and character of these colors preferred by children.

Vertical Pillar-Superlattice Array and Graphene Hybrid Light Emitting Diodes

Lee, Jung Min,Choung, Jae Woong,Yi, Jaeseok,Lee, Dong Hyun,Samal, Monica,Yi, Dong Kee,Lee, Chul-Ho,Yi, Gyu-Chul,Paik, Ungyu,Rogers, John A.,Park, Won Il American Chemical Society 2010 NANO LETTERS Vol.10 No.8

<P>We report a type of device that combines vertical arrays of one-dimensional (1D) pillar-superlattice (PSL) structures with 2D graphene sheets to yield a class of light emitting diode (LED) with interesting mechanical, optical, and electrical characteristics. In this application, graphene sheets coated with very thin metal layers exhibit good mechanical and electrical properties and an ability to mount, in a freely suspended configuration, on the PSL arrays as a top window electrode. Optical characterization demonstrates that graphene exhibits excellent optical transparency even after deposition of the thin metal films. Thermal annealing of the graphene/metal (Gr/M) contact to the GaAs decreases the contact resistance, to provide enhanced carrier injection. The resulting PSL-Gr/M LEDs exhibit bright light emission over large areas. The result suggests the utility of graphene-based materials as electrodes in devices with unusual, nonplanar 3D architectures.</P><P><B>Graphic Abstract</B> <IMG SRC='http://pubs.acs.org/appl/literatum/publisher/achs/journals/content/nalefd/2010/nalefd.2010.10.issue-8/nl100648y/production/images/medium/nl-2010-00648y_0005.gif'></P><P><A href='http://pubs.acs.org/doi/suppl/10.1021/nl100648y'>ACS Electronic Supporting Info</A></P>
