Since 'teaching coding' or 'programming' classes for computational thinking (CT) education in K-12 are renowned around the world, a pre-service teachers' readiness for integrating CT into their teaching subjects is important due to the fact that CT is considered to be another 'R' from algoRitm for 21st century literacy, in addition to the traditional 3R (Reading, Writhing, and Arithmetic) [2] and CT roles to other disciplines. With this rationale, we designed a guided instruction based CT course for pre-service teachers. We show the effectiveness of the program with respect to the teachers' attitude toward combining CT into their teaching subjects, and mindset changes of learning computing connected with the career development of the teacher themselves. The research focused on the instructional methodology of teaching programing for non-Computer Science Education (CSE) majors who are not familiar with computer science for alleviating the cognitive load of first exposure to programming course under the CT concepts.

The oriental medicine is not static knowledge. Since the publication of "Hwangjenaegyeong(黃帝內經)", it has unceasingly changed and developed, that changes and developments ate the reflex of culture and civil progression, and they also are active acceptance of the time's demand. when we look back into the history of the Oriental medicine, angle of understanding disease can be classified into two concepts ; internal-external and Eumyang. Internal-external is whether we find the source of disease internal or external. Eumyang is deciding which is more important between yin-essence and yang-gi which are components of the essence-gi of body. This thesis view course of development of theory of the oriental medicine since publication of "Hwangjenaegyeong(黃帝內經)" at certain point of internal-external and Eumyang and with those as background, will inquire into sameness and difference between the Korean medicine and the Chinese medicine, and provide an advanced course for the oriental medicine.

This paper proposes an autopilot system using a fuzzy PID controller to satisfy performances required for the automatic navigation of ships under various marine circumstances. The existing autopilot system using a PD type controller has difficulties in eliminating a steady-state error and compensating nonlinear characteristics of ships. The autopilot system using the proposed fuzzy PID controller has a self-tuning ability, an ability to compensate nonlinear characteristics, and an ability to turn at constant angular velocity. Therefore. it can naturally make a steady-state error zero, compensate nonlinear dynamic effect of ships, have an adaptability to parameter variation owing to shallow water effect, and have an ability to turn ship's course rapidly without overshoot through procedures of acceleration, constant, and deceleration of angular velocity for large course-changing.

This paper presents a synthetic control algorithm that generates the rudder command angle to track the optimal route which is composed of straight-lines among way-points with keeping a required error limit. The control algorithm comprises three main lgorithms that is a course-keeping algorithm that eliminates the yaw angle difference between optimal route and current route a track-keeping algorithm that tracks the optimal route among way-points and a turning-control algorithm that includes the generation of optimal turning routes and control method. The effectiveness of the proposed control algorithm is assured through computer simulation.

Background: While the application of procedural methods to solve the infertility problem has increased, the decline in the quality of life of women who experience infertility has been disregarded. Methods: This qualitative study used phenomenological analysis of data collected from 13 women with infertility in South Korea to reveal the subjective meaning of physical experiences perceived by women over the course of treatment. Results: Upon analyses of the treatment experiences of women with infertility in South Korea via a phenomenological analysis method, 10 themes were extracted and integrated into four theme clusters ("Perceiving infertility," "The body that gives birth," "A process in an endless tunnel," "Caring for my marginalized identity"). Conclusion: The results of this study suggest that women with infertility in South Korea perceived their own bodies as givers of birth living in traditional and patriarchal societies. A contextual flow proceeded to the final stage of women caring for their marginalized identity, which had suffered throughout the course of their infertility journey.

This study investigated how pre-service English teachers perceive the effects of machine teaching on their English writing competence. 35 Korean students who are majoring in English education participated in this study. The participants used machine translators for one of the required courses related to English composition. A survey and focus group interview were conducted at the end of the course. They were asked to answer to what degree they perceive the effects of machine translators on their writing in terms of lexical, sentential, and discourse levels. Furthermore, their perspectives on the effects of machine translation on English teaching including limitations of machine translators, were interviewed in more detail. The results show that the participants perceive machine translators quite positively in terms of improving their writing competence, but they also point out some critical limitations of machine translators. These findings have some pedagogical implications for English writing course instructors, English teacher educators, and program developers.

At present, the Department of Energy (DOE) in Unite State are directing the efforts of developing accident tolerant fuel (ATF) technology. As the first barrier of nuclear fuel system, the material selection of fuel rod cladding for ATFs is a basic but very significant issue for the development of this concept. The advanced cladding is attractive for providing much stronger oxidation resistance and better in-pile behavior under sever accident conditions (such as SBO, LOCA) for giving more coping time and, of course, at least an equivalent performance under normal condition. In recent years, many researches on in-plie or out-pile physical properties of some suggested cladding materials have been conducted to solve this material selection problem. Base on published literatures, this paper introduced relevant research backgrounds, objectives, research institutions and their progresses on several main potential claddings include triplex SiC, FeCrAl and MAX phase material Ti3SiC2. The physical properties of these claddings for their application in ATF area are also reviewed in thermohydraulic and mechanical view for better understanding and simulating the behaviors of these new claddings. While most of important data are available from publications, there are still many relevant properties are lacking for the evaluations.
