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.

This study analyze the trend and creativity of entry in chemistry sector of National Science Exhibition. For this study, award-winning entry in chemistry sector of National Science Exhibition during the last five years (2009-2013) were analyzed. The inquiry subject were classified six different items. The creativity evaluation rating of each entry was decided by a survey of the evaluator groups; teachers who participated in the training, winners' teacher. The results turned out as follows: First, In case of trying to choose inquiry subject of entry, it would be better for teacher to guide student into choosing everyday life or natural phenomenon in elementary school level, everyday life or academic area in middle school level, academic area in high school. Second, there was no correlation of creativity rating and actual award rating. Therefore, teacher will need to guide students' research synthetically in a variety of research areas.

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.

Collaborative filtering is used the most for recommendation systems because it can recommend potential items. However, when there are not many items to be evaluated, collaborative filtering can be subject to the influence of similarity or preference depending on the situation or the whim of the evaluator. In addition, by recommending items only on the basis of similarity with items that have been evaluated previously without relation to the present situation of the user, the recommendations become less accurate. In this paper, in order to solve the above problems, before starting the collaborative filtering procedure, we calculated similarity not by comparing all the values evaluated by users but rather by comparing only those users who were above the average in order to improve the accuracy of the recommendations. In addition, in the ceaselessly changing ubiquitous computing environment, it is not proper to recommend service information based only on the items evaluated by users. Therefore, we used methods of calculating similarity wherein the users' real time context information was used and a high weight was assigned to similar users. Such methods improved the recommendation accuracy by 16.2% on average.

Accurate predictions of the activation time for smoke detectors using a fire simulation is are required to ensure the reliability of the RSET (Required Safe Egress Time) calculation in the process of PBD (Performance-Based Design). The objective of this study was to enhance the accuracy of input parameters for the numerical models of smoke detector based on the FDS. To this end, a Fire Detector Evaluator (FDE) developed in previous studies was improved. The uniformities of flow and smoke inside the FDE were improved and accurate measurements of the obscuration per meter (OPM) related to detector operation were also performed through a decrease in the forward scattering of smoke particles. The input parameters using the improved FDE showed a significant difference from the previous FDE quantitatively. In particular, a larger difference was found in a photoelectric detector compared to an ionization detector. Considering that the operating conditions of smoke detectors are affected by the detector type, combustibles, smoke particulars, and color, the database (DB) on the input parameters for various detectors and combustibles should be built to improve the reliability of PBD in future studies.

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.

This study investigated mentor teachers' mentoring types and how the types of mentoring changed throughout the collaborative mentoring program for beginning science teachers who had difficulties in teaching practice. One-on-one mentoring meetings were audio-taped and transcribed for analysis. The result of the study showed that mentors took various roles such as Observer, Critical friend, Provider of feedback, Instructor, Role model, Evaluator, Counselor, and Equal partner. However, if mentoring did not bring about a change in the perception of a science instruction of a mentee teacher, there was no positive change in the teaching of the mentee teacher. Therefore, mentor teacher must have enough time to concretely discuss about mentee teachers' perception of a science instruction, mentoring method, etc. with mentee teacher before mentoring.
