Objectives The purpose of this study was to evaluate the psychometric properties of the Korean version of the Readiness to Change Questionnaire-Treatment version (RCQTV-K). Methods The participants were 92 patients who were seeking treatment of alcoholism in two hospitals for alcoholism. A confirmatory factor analysis was performed to test whether the factor structure of the RCQTV-K was consistent with the English version. Convergent validity was assessed by correlating the scores on the RCQTV-K with those on other scales (Alcohol Abstinence Self-Efficacy Scale, Beck Depression Inventory, Korean Version of Alcohol Use Disorders Identification Test). Results The factor structure of the RCQTV-K was consistent with the three-factor structure established for the original RCQTV. Cronbach’s α was high, indicating that the reliability of the items for each subscale was satisfactory. Allocated stage of change showed significant differences among the scores on the other scales. Conclusion The results of the present study indicate that the RCQTV-K is an effective and valid scale for evaluating the stage of readiness to change in patients seeking treatment for alcoholism. The findings suggest that the RCQTV-K is a promising assessment tool for use in the treatment and study of alcoholism.

This study aimed to examine teachers’ perceptions and practices of textbook reconstruction forelementary English. It also investigated the influential factors and the measures to facilitate textbookreconstruction. 140 elementary teachers were surveyed, and 6 teachers were also interviewed. Thefindings are as follows: First, teachers considered textbook reconstruction highly necessary and usefulto improve students’ English communicative competence, interest, and motivation. As students learnlanguage skills, teachers regard English textbook reconstruction differently from that of other schoolsubjects. Second, many teachers already implemented textbook reconstruction in their classes,although not by every teacher who voiced that textbook reconstruction was needed. Thereconstruction was applied to writing skills the most, followed by speaking, reading, and listening,indicating textbook reconstruction was more frequent in productive skills than in receptive skills. Textbook reconstruction was conducted in each textbook unit, using teacher-created materialsmostly, followed by materials from teacher communities and video clips from the Internet. Textbookactivities were replaced or supplemented with other activities or simply omitted. Third, factorsinfluencing textbook reconstruction were related to schools (administrative work, teaching materialsand facilities, and atmosphere), teachers (teaching method, English-subject teacher or homeroomteacher, co-teaching with native English-speaking teacher, and teacher training programs), andstudents (English level, English divide, participation, and interest). Finally, the following factorspromoted textbook reconstruction: reducing teachers’ administrative work, promoting participation inteacher training programs and communities, supporting teaching materials and facilities, sharingteaching materials and experiences, and creating favorable atmosphere and incentives for textbookreconstruction. Important implications regarding enhancing effective textbook reconstruction werefurther discussed. 본 연구는 초등 영어 교과서 재구성에 대한 교사의 인식과 실태를 조사하고, 영어 교과서 재구성에영향을 주는 요인을 분석하며, 교과서 재구성 활성화를 위한 개선방안을 모색하고자 했다. 이를 위해초등 영어 교사 140명을 대상으로 설문조사를 실시했고, 이 중 6명의 교사들을 대상으로 심층 면담을실시했다. 주요 연구 결과는 다음과 같다. 첫째, 교사들은 학습자의 영어 의사소통 능력과 흥미와 동기향상을 위해 교과서 재구성이 매우 유용하고 필요하다고 인식했다. 언어 기능을 습득하는 영어 교과의특성으로 영어 교과서 재구성은 타 교과의 교과서 재구성과 차별화된다고 보았다. 둘째, 교과서 재구성이 필요하다고 생각하는 모든 교사는 아니지만, 많은 교사들은 교과서 재구성을 수업 현장에서 시행하고 있었다. 언어 기능별로는 쓰기, 말하기, 읽기, 듣기 순으로 실행하여 표현기능에서 이해기능보다 더많이 교과서를 재구성하고 있었다. 재구성은 교과서 단원별로 하는 경우가 대부분이었고, 교수·학습 자료는 자체로 제작하거나 교사 커뮤니티나 인터넷 동영상 자료를 주로 활용하여, 교과서 일부 내용을 대체하거나 추가, 생략하는 유형으로 재구성했다. 셋째, 교과서 재구성에 영향을 미치는 주요 요인은 학교(행정 업무, 교수·학습 자료와 시설, 재구성 협의 학교 분위기), 교사(선호 교수·학습 방법, 전담교사 여부, 원어민 협력 여부, 교사의 교육관, 교사 연수), 학생(영어 능력, 학생 간 수준 차, 발화 참여도, 흥미나 관심사) 요인으로 드러났다. 또한 교사 연수와 교사 공동체가 교과서 재구성에 유용했지만, 교사 참여 기회 확대와 질적인 제고가 필요한 것으로 나타났다. 마지막으로, 교과서 재구성 활성화를 위한 개선사항으로는 교내 행정 업무 경감, 연수 참여 기회 증진, 교구 및 시설 지원, 재구성 자료와 경험 공유,재구성 권장 분위기 및 보상제도 마련 등이 제안되었다. 본 연구는 효과적인 초등 영어 교과서 재구성을 통해 영어교사, 영어교사교육가, 관리자, 정책 입안가들에게 중요한 시사점을 주고 있다.

Research on Visual-to-Auditory (V2A) which uses neural facilitation to transfer visual information to auditory information is actively ongoing. However, existing V2A methods have provided users with limited information by simply converting visual information to auditory information. To provide more information to the users, it is necessary to generate and transmit augmented visual information by integrating it with other sensory information. Recently, methods for generating augmented visual information by integrating auditory and visual information are being studied, but there is a drawback in that they cannot generate images optimized for sound intensity by not considering the rich intensity of sound. To solve this problem, in this paper, a method of classifying sound and converting the classified result into sound intensity to generate images optimized for sound intensity is proposed. The results of applying the proposed method to a face image generation model in experiments showed that the proposed method can generate face images utilizing sound information when sound intensity is considered.

The chemical mechanical planarization (CMP) is a process of physically and chemically polishing the semiconductor substrate. The planarization quality of a substrate can be evaluated by the within wafer non-uniformity (WIWNU). In order to improve WIWNU, it is important to manage the pad profile. In this study, a device capable of non-contact measurement of the pad thickness profile was developed. From the measured pad profile, the profile of the pad surface and the groove was extracted using the envelope function, and the pad thickness profile was derived using the difference between each profile. Thickness profiles of various CMP pads were measured using the developed PMS and envelope function. In the case of IC series pads, regardless of the pad wear amount, the envelopes closely follow the pad surface and grooves, making it easy to calculate the pad thickness profile. In the case of the H80 series pad, the pad thickness profile was easy to derive because the pad with a small wear amount did not reveal deep pores on the pad surface. However, the pad with a large wear amount make errors in the lower envelope profile, because there are pores deeper than the grooves. By removing these deep pores through filtering, the pad flatness could be clearly confirmed. Through the developed PMS and the pad thickness profile calculation method using the envelope function, the pad life, the amount of wear and the pad flatness can be easily derived and used for various pad analysis.

In traditional Document Based Configuration Management(DBCM) environment, changes in a system's configurations are hard to be reflected to existing engineering documents. This nature of DBCM triggers unconformities of system configurations which could become great risks. Model-based Configuration Management(MBCM) has been introduced to solve the problem of DBCM by managing system's configurations through an unified model. Therefore, it is important to model engineering documents in a general modeling language, down to low-level information items to develop traceability and flexibility of a system's engineering information. So, in the research, to explore the possibility of Model-based Approach(MBA) in the field of configuration management, a development of a systems requirement document model using SysML based Views & Viewpoints concept has been studied.
