The study examined the effects of parenting process(supportive and involving mother-adolescent relationship, father-adolescent relationship) and school process(teachers' support, school life satisfaction) on adolescents' academic achievement and self-evaluation. Participants were 1787 middle school students (902 boys, 885 girls) in KEEP(Korean Education and Employment Panel). Structural equation modeling indicated that parenting and school process influenced adolescents' self-evaluation through adolescents' academic achievement. Also, the analysis with One Way ANOVA revealed that positive school (parenting) processes can serve a protective-stabilizing function when parenting(school) processes are negative.

This study conducted a case study on the process-centered evaluation competency of a middle-school/high-school science teacher using Teacher's Process-centered Evaluation Competency (T-PEC) measurement tool. The case analysis shows that teacher A in a middle school represents high competency of process-centered evaluation planning and cooperative communication while the competency of utilizing process-centered evaluation results is low owing to the characteristics of non-standardized areas. Teacher B in a high school shows high level of cooperative communication competency whereas low level of process-centered evaluation execution competency because the freedom given to students is not enough during the process of evaluation. The teacher also shows very low level of utilizing process-centered evaluation results due to the lack of time and the school culture not giving feedback to the students. According to cross-case analysis, teacher A and B both represent the highest level of collaborative communication competency and the lowest level of utilization process-centered evaluation results competency. And the lack of clear criteria for process-centered evaluation leads to different understanding of process-centered evaluation between the two teachers, and teacher B shows low the level of utilizing process-centered evaluation affects results due to the students not being concerned on feedback, security problem, and the reality focusing on the university entrance examination in high schools. Based on the results, this study suggests providing clear guidelines of process-centered evaluation to teachers, introducing an application in order to solve the time-lack problem pointed out as the biggest problem of process-centered evaluation, ensuring objectivity and security about process-centered evaluation results, and building the school culture such as the expanded application of standardized areas in order to implementing process-centered evaluation.

Coating process plays an important role in information technology such as display, battery, chip manufacturing and so on. However, due to complexity of coating material and fast deformation of the coating flow, the process is hard to control and it is difficult to maintain the desired quality of the products. Moreover, it is hard to measure the coating process because of severe processing conditions such as high drying temperature, high deformation coating flow, and sensitivity to the processing variables etc. In this article, the coating process is to be re-illuminated from the rheological perspectives. The practical approach to analyze and quantify the coating process is discussed with respect to coating materials, coating flow and drying process. The ideas on the rheology control of coating materials, pressure and wet thickness control in patch coating process, and stress measurement during drying process will be discussed.

Purpose: The object of this study is to identify the reason why school health education act had not been enforced properly, and to find out implications for improving. Methods: The implementation process of school health education act was described and the imperatives of the process were analysed. M. Rein's Policy Implementation Model was used as an analysis framework. The sources of this study was based on the minutes of parliament, government reports, materials for the meetings of policy makers, the press, etc. Results: The school health education act clarified mandatory and systemic health education in it, but it did not clearly mentioned about 'the introduction of compulsory health education subject'. The bureaucrats of National Educational Ministry who are responsible for policy implementation, did not behave in a friendly manner toward the school health education act. What is more, the ways of mandatory and systemic school health education could not be discussed reasonably in the implementation process. Through this study it was found that the rational-bureaucratic imperative played the main role in the implementation process of school health education act due to the limitation of the legal imperative and the consensual imperative. Conclusion: The result of this study suggests the strong need to make up for the defect of the two imperatives, and to reform the rational-bureaucratic imperative.

Bony lesions of the glenoid and Hill-Sachs lesions are the most common injuries after a first-time traumatic shoulder dislocation. However, fracture of the coracoid process after traumatic shoulder dislocation is rare. A single, open surgical procedure could be performed by a Latarjet procedure using a fractured fragment of the coracoid process. If a fracture of the coracoid process is associated with a traumatic anterior shoulder dislocation, the Latarjet procedure may be the most appropriate surgical option.

Styloid process is a slender pointed bone of variable length, which project downward, forward, and slightly medialward from the posteroinferior portion of the tympanic part of the temporal bone. Embryologically, the styloid process is derived from Reichert's cartilage, a structure of second branchial arch origin. Most patients with elongated styloid process remain asymptomatic, but some patients complain pain and sensation of foreign body in the throat, dysphagia, dysphonia, referred otalgia. Recently, we have experienced a case of elongated styloid process in a fifty-nine year old man. He had been suffered from Rt. side sore throat, headache and pharyngeal discomfort during head movement. Through various X-ray examination, Xeroradiography, and palpation of tonsillar fossa, elongated styloid process on Rt. side was confirmed. Under the general anesthesia, it was successfully removed out via transoral approach technique, described by Eagle. The resected styloid process was 2.5cm in it's length and he was freed from the symptoms without further complication.

This paper proposes a looperless tension control algorithm which is robust to disturbance and tensional variation in rolling process using SVR(Support Vector Regression). Hot rolling process which is global technology to coil steel after continuous finishing process for welded bars followed by roughing mill process, becomes hot issue. Finishing mill process not only makes it possible to produce ultra thin steel strip(0.8 mm) but enhance the quality of terminals of coil, which increases the productivity due to faster process. Constant tension control between stands in hot rolling process is essential to enhance the quality of steel. Sensorless tension control is under research by some advanced companies to replace the conventional tension control method because in continuous finishing mill process, it is impossible to install the looper used in conventional control system. Simulation results show the effectiveness of the proposed algorithm.

The purpose of this study is to find out the level of science teaching efficacy belief in the elementary school teachers and to find out the students' science process skills and scientific attitudes according to the level of the teacher's science teaching efficacy belief. After measuring science teaching efficacy belief of 109 teachers from nine elementary schools, three teachers who received the high score and three teachers who received the low score were selected from each 5th and 6th grade. Science process skills and scientific attitudes of 331 students who were in the selected 12 teachers' classes were measured. The results of this study were as follows; First, there were significant differences on the elementary school teachers' science teaching efficacy belief according to teacher's gender and career. The men's average score was clearly higher than women's average score on personal science teaching efficacy in science teaching efficacy belief according to teacher's gender. There was a obvious difference between the group of more than six-year less than ten-year and the group of more than fifteen-year less than twenty-year, the group of more than twenty-year on science teaching outcome expectancy in science teaching efficacy belief according to teacher's career. Second, there was not a evident difference on the elementary school students' science process skill according to the level of the elementary school teachers' science teaching efficacy. Third, there was a distinct difference on the elementary school students' scientific attitude according to the elementary school teachers' science teaching efficacy. There was a significant difference on the openness and the endurance in each scientific attitude. The level of science teaching efficacy belief in the elementary school teachers had few effects on the elementary school students' science process skill, on the other hand the level of science teaching efficacy belief in the elementary school teachers had an positive effect on the elementary school students' scientific attitude.
