The prevalence of prostate cancer is stiffly increasing in Korea. In contrasts to the frequency of occurrence, there is no definite guideline for the cut off value of serum PSA. So, we reviewed the usefulness of serum PSA and recently reported guidelines in the prostate cancer detection. Nowadays, the cut off value of PSA continued to change, moreover, it is difficult to satisfied both sensitivity and specificity, at the same time. Also, the value of PSA relies on the assay method or laboratory. Various methods such as the percent of free PSA, PSA velocity and PSA doubling time have been used to enhance the detection rate during prostate biopsy. However, these methods did not make certainty in deciding whether performing the prostate biopsy. To complement the uncertainty of PSA and its derivatives, the new ways such as proPSA, PCA3 and gene fusion have been recently documented. Currently, the clearly indication of prostate biopsy is placed in controversy. Therefore, in the future, new methods to overcome non-specificity of PSA should be considered.
국어과 동료 교사의 수업 논평을 통해 본 국어 교사의 수업 전문성

본 연구의 목적은 국어과 교사가 동료의 수업을 논평하면서 주목한 국어 수업에 대한 ‘실제적 평가 기준’은 어떠하며, 그것의 시사점은 무엇인지를 알고자 하는 데 있다. 국어과 교사의 논평을 분석해 본 결과 ‘학생의 학습(적극적인 참여), 교사의 설명, 피드백, 주의 집중과 수업 장악, 교사/학생의 상호 작용, 수업목표 제시’ 등의 순으로 지적(指摘) 빈도가 높았다. 이에 지적 빈도가 높은 항목을 중심으로 ‘국어과 수업의 실제적 평가 기준’을 마련하였다. 이런 ‘실제적 평가 기준’은 국어 교사들의 수업 평가 관점과 기준이 반영된 결과이면서 국어 수업에 대한 현상적 관점이라 볼 때, 국어 수업이 교사의 교수 행위와 학생의 학습 행위가 교섭적으로 작용하는 협력의 과정이라는 시사점을 던져 준다. Objective of this study is to identify the ‘practical teaching evaluation criteria’ used by the Korean language teachers in their peer review and the implications of such criteria. The evaluated comments of these Korean language teachers focused most frequently on students’ active participation, and it was followed by teacher’s explanation, feedback, concentration, presence, interaction with students, and offering the objective of the class. Thus produced is the ‘practical class evaluation criteria’ based on those evaluation points of higher importance. This ‘practical evaluation criteria’ therefore reflects the viewpoints and criteria of the Korean language teachers in class evaluation and stands as the practical perspective on Korean language classes, and also implies that a Korean language class is a cooperative process of teacher’s teaching and students’learning.

High pressure deuterium (HPD) annealing is an advancing technology for the fabrication of modern semiconductor devices. In this work, gate-enclosed FETs are fabricated on a silicon substrate as test vehicles. After a cycle for the HPD annealing, the device parameters such as threshold voltage (V<sub>TH</sub>), subthreshold swing (SS), on-state current (I<sub>ON</sub>), off-state current (I<sub>OFF</sub>), and gate leakage (I<sub>G</sub>) were measured and compared depending on the HPD. The HPD annealing can passivate the dangling bonds at Si-SiO<sub>2</sub> interfaces as well as eliminate the bulk trap in SiO<sub>2</sub>. It can be concluded that adding the HPD annealing as a fabrication process is very effective in improving device reliability, performance, and variability.

Purpose: Our study aimed to evaluate the predictive value of multiparametric magnetic resonance imaging (mpMRI) to assess the capsular extension of prostate cancer. Risk factors for extraprostatic invasion or microscopic invasion of bladder neck (pT3a stage) in the cases showing localized disease findings on MRI scan were also identified. Materials and Methods: We identified 198 patients who underwent robot-assisted or conventional laparoscopic radical prostatectomy in our institute between June, 2016 and May, 2018. Altogether, 170 patients with preoperational mpMRI scans and complete pathologic data were included. Positive and negative predictive values of mpMRI to detect capsular extension were estimated. Chi-square test was performed for ratio variables. Logistic regression analysis was performed to identify capsular invasion risk factors. Results: Median age and prostate-specific antigen level were 68 years and 7.5 ng/mL, respectively. Based on findings, 16 patients (9.4%) were identified as cT3a stage (unilateral or bilateral extraprostatic extension), whereas 37 patients (21.8%) as pT3a stage. Positive and negative predictive values of mpMRI to detect capsular extension were 75.0% and 73.9%, respectively. In the logistic regression analysis, positive biopsy core rate was the significant predictor for pT3a disease in the patients with negative capsular invasion findings on mpMRI (p<0.001). According to receiver-operating characteristic curve (area under the curve=0.691, p=0.001), the positive biopsy core rate of 0.275 was the best threshold. Conclusions: Multiparametric MRI is an appropriate test to predict pT3a disease preoperatively. The patients with positive core rate over 0.275 may have pT3a diseases despite negative image findings.

Personality characteristics were studied by means of SCL-90-R test. Behavioral problem and pain site was studied (Sleep disturbance, irregular eating habit, decreased physical activity, decreased social activity, increased emotional tension) by examination sheets. This study was conducted to examine the mature and extent of psychological difference between the students who failed the college-entrance examination and freshmen and to determine whether psychological distress acts as a precipitate for craniocervical pain. 96 students who failed the college-entrance examination (examination-failed student) and 86 freshmen were included in this study. The obtained results were as follows ; Mean T-score of SCL-90-R primary scale and global indies in examination-failed students were significantly higher than the freshmen group. In comparison with examination-failed student group and freshman group, the prevalence of neck and shoulder pain was significantly higher than the freshman group. When the study and control group were compared in behavioral problems the study group had not more sound sleep than the control group. The study group had more irregular eating habit than control group. The study group had the lower physical activity than control group. The study group had the lower physical activity than control group. The study group had poor social activity than control group. There were no significant difference in emotional tension.
