Research on strategic Code-Switching (CS) of second language learners in teaching English in English (TEE) program provides an elaborate framework for analyzing how learners manage to express themselves in spite of their limited knowledge of the target language. This research presupposes that L2 learners' CS presents innovative solutions for communicative strategy, and that CS used as communicative strategy can promote L2 learners' language acquisition. The major questions of current research involve examining the significant patterns of different functions of CS in L2 learners' interaction and investigating L2 learners' CS styles according to the different functions of CS. The implication of CS utility is regarded as a teaching technique in the TEE program. Recorded transcript is analyzed to trace the same pattern and the categorization of CS as well as to recognize the functions of CS and their ratio. Hence, this leads to the conclusion that learners' negotiation between code selection and communication intention occurs in patterns. The learners' CS tends to be predictable, reproductive, and systematic, as one of the language acquisition phases. Therefore, the attention to the CS in the TEE program should be redirected in communication substantiality toward the principles of pragmatics. As an additional advantage of the CS analysis, this research elaborates on a conceptual acceptance of CS as a set of learners' strategies in the TEE program.

This study explored how teachers and students in different countries discursively interact to build 'Classroom Science Knowledge' (CSK) - the knowledge generated situatedly in the context of the science classroom. Data came from publicly released $8^{th}$ grade science classroom videos of five nations who participated in the Third TIMSS (Trend in International Mathematics and Science Study) video study. A total of ten video-recorded science lessons and their verbatim transcripts were selected and analyzed using a framework developed by the researchers of the study. It was revealed that a range of discourse modes were utilized and these modes were often sequentially connected to build CSK in the science classrooms. Although dominant discourse modes and their sequences varied among different lessons or different countries, the study identified three salient patterns of science classroom discourse: teacher-guided negotiation and the sequences of exploring - building on the shared and retrieving - elaborating. These patterns were found to be different from the discursive features commonly witnessed in the community of professional scientists and interpreted as implying the existence of unique epistemic cultures shared in science classrooms of different countries. Further studies are suggested to reveal detailed characteristics of these epistemic cultures of science classrooms, as well as to confirm whether any cultural traits inherently shape the differences in science classroom discourse among different nations.

A shop floor control system(SFCS) performs the production activities required to fill orders. In order to effectively control these activities, the autonomous agent-based heterarchical shop floor control architecture is adopted where a supervisor does not exist. In this paper, we define functional perspective of the heterarchical shop floor control using planning, scheduling, and execution modules. In particular, we focus on an execution module that can coordinate the planning and scheduling modules and a general execution module that easily can be modified to execute the other equipment. The execution module can be defined informally as a module that downloads and performs a set of scheduled tasks. The execution module is also responsible for identifying and resolving various errors whether they come from hardware or software. The purpose of this research is to identify all the execution activities and solving techniques under the assumptions of the heterarchical control architecture. And we model the execution module in object-oriented modelling technique for generalization. The execution module modeled in object-oriented concept can be adopted to the other execution module easily. This paper also proposes a classification scheme for execution activities of the heterarchical control architecture. Petri-nets are used as a unified framework for modeling and controlling execution activities. For solving the nonexistence of a supervisor, a negotiation-based solution technique is utilized.

Hydro-electric power generation from multi-purpose dams has been playing important roles in the electric power supply network in Korea. Although the total share of hydro power in national electricity supply now becomes very small, the peak-shaving and frequency control capability of hydro power helps the power company enormously in maintaining the quality of power. But since the company that builds and operates the multi-purpose dams in Korea has to sell all the electricity produced to the monopolistic utility, there have been various problems in justifying the investment, designing pricing mechanism, and controlling operations of the power plants. In addition, economic evaluation of the hydro power has been distorted by a variety of reasons and hence it has been very difficult to encourage effective development and utilization of national water resources. To make the problem worse, both parties are public companies with X-inefficiency problems. Thus, changing environment requires to reengineer the system that governs hydro power generation. We address the problems of Korean hydro-electric power generation system in four areas: the investment justification process, the operations decison right of the hydro power plants, the pricing of the purchased-power, and the negotiation of contract revision. Then we propose improvement directions of new hydro-electric power system in view of static and dynamic efficiency, X-inefficiency and equity.

Purpose: To promote condom use for young men, there is necessary to meet their varying needs for condom. The purpose of this study was to examine what predicts condom use intention according to experience of sexual intercourse among Korean male college students. The conceptual framework for the study was the theory of planned behavior and the health belief model. Methods: A cross-sectional descriptive design was used with self-report questionnaires, which were completed by 399 subjects. Logistic regression analysis was done to examine predictors of condom use intentions according to experience of sexual intercourse. Results: The susceptibility to sexual transmitted diseases/ Acquired Immune Deficiency Syndrome (STDs/AIDS) and pregnancy and benefits from condom use were significant predictors of condom use intentions in the non-experienced group. The significant predictors of condom use intention for the experienced group were barriers to condom use and condom use self-efficacy. Conclusion: These findings suggest that sex education program should be developed to overcome barriers to condom use, enhance condom use self-efficacy, and maximize the benefits from condom use as well as increase the perceived susceptibility to STDs/AIDS and pregnancy. To enhance condom use self- efficacy, practicing and increasing ability in interactive negotiation to use condom should be included.

East Asia's Regional Comprehensive Economic Partnership (RCEP) came into force in 2022 as the world's largest free trade agreement. RCEP was concluded, signed and brought into force in the face of major international uncertainty and is a significant boost to the global trading system. RCEP brings Australia, China, Japan, South Korea and New Zealand into the same agreement with the ten member ASEAN group at its centre. It keeps markets open and updates trade and investment rules in East Asia, a major centre of global economic activity, at a time of rising protectionism when the WTO itself is under threat. The agreement builds on ASEAN's free trade agreements and strengthens ASEAN centrality. One of the pillars of RCEP is an economic cooperation agenda which has its antecedents in ASEAN's approach to bringing along its least developed members and builds on the experience of capacity building in APEC and technical cooperation under the ASEAN Australia-New Zealand Free Trade Agreement. There is an opportunity to create a framework that facilitates deeper economic cooperation that involves experience-sharing, extending RCEP's rules and membership at the same time as strengthening political cooperation. The paper suggests some areas that might be best suited to cooperation - that is confidence and trust building instead of or before negotiation - and discusses how non-members may be engaged and the membership expanded. Options such as multilateralising provisions and becoming a platform for policy convergence and coordinating unilateral reforms are canvassed.

현재, 지역경제통합의 가장 일반적인 형태는 두 나라 또는 그 이상의 나라들이 쌍무적 형태로 체결하는 자유무역협정(FTA)이다. 2010년 6월 29일 중국과 대만은 중국 충칭(重慶)에서 경제협력기본협정(ECFA)을 체결함에 따라 한 중 FTA 역시 최근 들어 재조명되기 시작했다. 중국은 한국의 제1위의 교역상대국이고, 2010년 5월 기준으로 중국은 한국의 제1위의 수출상대국이며, 한국은 중국의 제2위의 수입대상국이다. 또한 대만은 대(對)중국 교역에 있어서 한국과 교역구조가 비슷하고 경쟁구도를 유지하고 있다. 그렇기에 2010년 6월에 체결한 중 대만 ECFA는 중국과 한국의 교역에 있어서 큰 영향을 미칠 것이며 한국의 국내산업과 중국과의 교역에 치명적 영향을 미칠 것이다. 따라서 본 논문에서는 중국과 대만이 체결한 ECFA의 배경 및 진행과정과 협상의 핵심내용에 대해서 살펴보고, 현재 논의되고 있는 한 중 FTA에 대해서도 그 정파와 예상쟁점 사항을 분석해 보도록 한다. 이를 통해 중 대만 ECFA가 한국의 대(對)중국 교역에 미칠 영향과 한 중 FTA에 시사하는 바를 살펴보는 것이 본고의 목적이라고 할 수 있다.

이 연구는 나노기술과 관련된 사회윤리적 쟁점 맥락에서 이루어진 대학생의 논증담화의 특성을 개인-집단중심성향에 따라 분석하는 것을 목적으로 한다. 나노기술은 다양한 분야에서 활용되고 있으나 그에 못지않게 위험성을 내포하고 있어 과학기술과 관련된 사회쟁점의 특징을 보여주는 주제이다. 이 연구에서는 A대학의 교양수업을 수강한 대학생 33명을 대상으로 개인중심성향과 집단중심성향에 따라 구분하고, 나노기술과 관련된 사회윤리적 쟁점 맥락에서 진행한 논증담화를 담화클러스터와 담화요소에 따라 분석하였다. 연구결과, 전반적으로 대학생들은 나노기술과 관련한 논증을 진행할 때 본인의 입장을 교환하고 자료를 탐색함으로써 의견을 조율하는 방식으로 참여하였으며, 그 중에서도 나노기술의 혜택과 잠재적인 위험성을 탐색하는 데 많은 시간과 노력을 투자하였다. 이때 개인중심성향집단과 집단중심성향집단은 담화클러스터와 담화요소의 연결고리에 있어 차이가 있었다. 집단중심성향집단은 개인중심성향집단에 비해 구성원 간의 의견을 조정하고 합의하는 담화클러스터가 길게 등장하였으며, 의견조정 및 합의 클러스터 내부에 등장하는 담화요소와 그 연결고리의 모습 또한 다소 차이가 있는 것으로 드러났다.
