Objectives : The evaluation of disability after trauma in psychiatry is relatively subjective compared with other departments. A consensus among evaluators could improve reliability of evaluations. We compared disability rate of common psychiatric disorders without definite brain injury depending on their diagnosis from experienced evaluators in Korea. Methods : A written questionnaire was mailed to each evaluator and the reply was analyzed. The questions included disability rate ranges of postconcussional syndrome, PTSD and depression. Other questions related with admission for evaluation, expected duration of treatment, life expectancy and need of supporting person were also asked. Results : Range of disability rate were from $8.6{\pm}4.5%$ to $26.6{\pm}12.8%$ in postconcussional syndrome, from $10.4{\pm}6.8%$ to $36.4{\pm}13.8%$ in PTSD and from $10.0{\pm}4.6%$ to $30.6{\pm}10.3%$ in depressive disorder. There were lots of diversity in expected duration of treatment with psychiatric disability. Decline of life expectancy and need of supporting person were considered at least 50% of disability. Conclusion : There is much diversity in evaluation of psychiatric disabilities with disability rate and expected duration of treatments even among experienced evaluators. A common consensus among experts may increase reliability of psychiatric evaluations after trauma.

Concepts of mediation and conciliation as alternative dispute resolutions are often confusingly used. As to what is meant by mediation and conciliation, there is no uniform legal definition. However, there has been a distinction between two methods of dispute settlement under the international law (UN Charter, WTO DSU, NAFTA, EU mediation directive, WIPO Mediation Rules) although there is no clear definition on the terms of mediation and conciliation. And also under the domestic law such as U.K, France, Germany, a clear distinction has been made between two terms. Mediation means a facilitated negotiation between two parties through the intervention of a third party. A third and neutral party (mediator) help the parties in dispute to find their solution by managing a certain mediation protocol and facilitating communication between the parties while in conciliation, a third party evaluative the case and can suggest the parties a legally non-binding solution. Once the parties accept it, it becomes binding between them. However, in the U.S,, it seems that there is no practical use of distinguishing mediation and conciliation. The term of mediation is more commonly used than the term of conciliation and it has two kinds of mediation such as facilitative and evaluative mediation. Korea's conciliation system is close to conciliation or evaluative mediation. In conclusion, what is distinct between mediation and conciliation is the role of third party. If a neutral third party takes a role of advisor or facilitator, then he or she may employ a proper protocol to help the parties to find themselves their solution (mediation) while if a neutral person plays a role of evaluator, then he or she listens to the parties and suggest a solution to them (conciliation).

The Reid colposcopic index (RCI) helps physicians for interpret the results of colposcopic examination. To compare the accuracy of RCI in colposcopic evaluation between general and oncologic gynecologists, this prospective trial was conducted by invited women over 20 years of age who were scheduled for a colposcopy at Chiang Mai University Hospital between August, 2008 and May, 2014 to participate. Pregnant patients or those having a history of hysterectomy or conization were excluded. During the colposcopy, all patients were simultaneously evaluated by general and oncologic gynecologists utilizing the RCI. Further management with either a biopsy or LEEP in each patient was dependent on the decision of the attending oncologic gynecologist. The accuracy of the RCI in diagnosing HSIL or more was calculated by the comparison with the final histology. Finally, 135 patients were recruited into this study. The sensitivity, specificity, PPV, NPV, and accuracy of RCI in diagnosing HSIL or more in general gynecologists were 45.2%, 80.7%, 41.1%, 83.2% and 72.6% while in the oncologic gynecologists were 51.6%, 85.6%, 51.6%, 85.6% and 77.8%, respectively. The difference in accuracy between evaluator groups was not significant (p-value=0.28). Of 3 patients with invasive cervical cancer, all were undetected by the general gynecologists using RCI while only 1 invasive cervical cancer was missed via RCI by the oncologic gynecologists. We conclude that RCI could be used by general gynecologists in provincial hospitals with major concerns about missing invasive cervical cancer. A short training period regarding colposcopy might help to resolve this problem.

The aim is to investigate the analgesic effect of transcranial direct current stimulation(tDCS) on central neuropathic pain(CNP) in spinal cord contusive rat model. Twenty Sprague-Dawley rats($250{\pm}50$ g, male) were used. Thoracic spinal cord(T10) was contused using New York University(NYU) spinal cord impactor. The animals were randomly assigned to two groups; GroupI: Non-treatment after SCI induction(n=10), GroupII: application of tDCS(0.1 mA, 20 min/time, 2 times/day, 5 days/6week) after SCI induction(n=10). Assess the effect of tDCS using the Basso Beattie Bresnahan(BBB) locomotor rating scales, Touch $test^{TM}$ sensory evaluator(TTSE), Plantar test$^{\circledR}$after contusion at the $2^{nd}$, $3^{rd}$, $4^{th}$, $5^{th}$, $6^{th}$ week and the immunohistochemistric response of c-fos in the thalamus, cerebral cortex after contusion at the $3^{rd}$, $6^{th}$ week after SCI. The scores of BBB scales were significantly different from $3^{rd}$week. TTSE were different significantly over time, but there were no differences at each evaluation times on between-measure time effects. Plantar test were different significantly over time and there were difference at the $4^{th}$, $6^{th}$ week after SCI on between-measure time effects. Also, immunohistochemistric response of c-fos was reduced significantly from $3^{rd}$, $6^{th}$ week after SCI in tDCS group compared with control group in thalamus and cortex. These results identified that tDCS of non-invasive therapeutic method may have beneficial analgesic effect on CNP after SCI with behavioral test and immunohistochemical test.

협력적 필터링은 잠재적인 항목을 추천할 수 있어서 추천시스템에 가장 많이 사용되고 있다. 그러나 협력적 필터링은 평가항목이 적을 경우, 평가자의 상황이나 기분에 따라 유사도나 선호도에 큰 영향을 끼칠 수 있다. 또한 사용자의 현재 상황을 전혀 고려하지 않고 과거에 평가한 항목만으로 유사도를 계산하여 추천하여 추천의 정확도가 떨어지게 된다. 본 논문에서는 위와 같은 문제점을 해결하기 위해, 먼저 협력적 필터링 과정을 수행하기 전 사용자들이 평가한 모든 값을 비교하지 않고 평균 이상인 사용자들만을 비교하여 유사도를 계산함으로써 추천의 정확성을 높였다. 또한 끊임없이 변화하는 유비쿼터스 컴퓨팅 환경에서 사용자의 평가 항목만으로 서비스 정보를 추천하는 것이 적합하지 않기 때문에, 사용자의 실시간 컨텍스트 정보를 이용하여 비슷한 사용자들에게 높은 가중치를 적용하여 유사도를 구하는 방법을 사용하였다. 이러한 방법을 사용한 결과, 추천의 정확도가 평균적으로 16.2% 향상되었다.

성능위주 소방설계(PBD)의 과정에서 요구피난시간(RSET) 산정의 신뢰성을 확보하기 위해서는 화재시뮬레이션을 이용한 정확한 연기감지기 작동시간 예측이 필수적이다. 본 연구의 목적은 FDS 기반의 연기감지기 수치모델에서 요구되는 입력인자의 정확도를 개선시키는 것이다. 이를 위하여 선행연구에서 적용된 화재감지기 시험장치(FDE)의 개선이 이루어졌다. 구체적으로 FDE 내부의 유동 및 연기농도 균일성이 개선되었으며, 연기입자의 전방산란 저감을 통해 감지기가 작동되는 순간의 정확한 광 소멸률이 측정되었다. 개선된 FDE를 이용한 입력인자는 기존 결과와 정량적으로 상당한 변화를 보이고 있으며, 이온화식 감지기에 비해 광전식 감지기에서 더 큰 차이가 확인되었다. 연기감지기의 작동조건은 감지기 종류, 가연물, 연기입자 및 색상에 따라 큰 차이가 발생됨을 고려할 때, PBD의 신뢰성을 향상시키기 위하여 향후 연구에서는 보다 다양한 감지기 및 가연물에 대한 입력인자 DB가 구축되어야 할 것이다.

Objectives:This study aims to investigate the correlation between the measurements of Praat as an acoustic evaluation and those of GRBAS and CAPE-V as perceptual rating tool respectively. Through this, it also tries to find out parameters to which attention should be paid when an evaluator, who is untrained in auditory-perceptual voice evaluation, conducts voice evaluation with objective tool. Materials and Methods:Voice samples of this study were 33 vocal polyp patients(23 males and 10 females) who visited our Department of Otorhinolaryngology. They sustained vowel voices of 'e' were recorded and acoustically analyzed. Results:As the results of correlation analysis between GRBAS and Praat measurements, G scale and R scale showed statistically significant correlation with Jitt, Shim and NHR. And it is found that B scale represented significant correlation with Jitt, S scale with Shim. As the results of analysis on correlation with CAPE-V and Praat measurements, OS scale and R scale showed statistically significant correlation with Jitt, Shim and NHR. B scale represented significant correlation with Jitt, S scale with Shim. Conclusion:Although, both GRBAS and CAPE-V were highly reliable, in comparison between CAPE-V and Pratt, more parameters that showed statistically significant correlation are observed, which implies that VAS has more potential to make detailed evaluation than ORD.

Objectives : The purpose of this study was to examine the problems with the current practical examination, to suggest some of the right directions for that and to facilitate the improvement of the exam. Methods : The subjects in this study were the selected professors involving professors in charge of practice and the selected clinical dental hygienists who had ever served as the graders of the national practical exam. Results : A direct practical test was required in the national practical exam (77.3%), and educational facilities(79.2%)(p<0.05). They didn't put confidence in the national practical exam(81.0%) nor viewed the items about the removal and detection of dental calculus as appropriate(58.5%), either. Specifically, the items were considered to be more inappropriate by the professors in charge of practice(74.3%) than by the other professors and clinical dental hygienists(p<0.05). Concerning ways of administering the national exam, the largest group preferred that a professional evaluator should evaluate students in person by visiting their colleges(66.8%). Conclusions : The above-mentioned findings illustrated that both of the dental hygiene professors and the clinical dental hygienists thought the current national dental hygienist practical exam would absolutely be necessary since it exerted a great influence on education and educational facilities, and that the national exam should be improved to gain more confidence, to solve comprehensive problems and to ensure the efficiency of administration.

이 연구는 교수 활동에 어려움을 겪는 초임 중등과학교사를 대상으로 실시한 협력적 멘토링 과정에서 멘토교사의 멘토링 유형이 어떻게 나타나는지 살펴보고, 멘토링이 진행됨에 따라 멘토교사의 멘토링 유형이 어떻게 변화하는지 알아보고자 하였다. 이를 위하여 멘토링에서 수집된 멘토교사와 멘티교사의 일대일 멘토링 대화를 질적으로 분석하였다. 연구 결과, 협력적 멘토링 과정에서 멘토교사는 관찰자, 비판적 동료, 지원자, 지시자, 역할 모델, 평가자, 상담자, 동반자 등 다양한 역할을 수행하였다. 그러나 멘토교사의 멘토링이 멘티교사의 과학교수에 대한 인식 변화를 가져오지 못하는 경우에는 멘티교사의 수업에서 긍정적인 변화가 나타나지 않았다. 따라서 멘토교사는 멘토링을 실시하기 전 멘티교사와 함께 과학교수에 대한 신념, 멘토링 방법 등에 관해 구체적으로 논의하는 시간을 충분히 가져야 할 것이다. 또한 멘토교사는 멘티교사의 수업 전문성 향상을 유도하기 위해 다양한 역할이 존재하고 있음을 인식하고, 자신의 멘토링 과정을 평가하는 데에도 이를 활용할 수 있어야 할 것이다.
