본 연구는 교수자가 학습자를 위해 긍정적 가치탐색을 효과적으로 적용할 수 있도록 4D 프로세스 기반 학습모형을 개발하고 학습유형을 분류하여 연구하는 것을 목적으로 하였다. 긍정적 가치탐색 교육 방법은 학습자의 사고방식과 행동 변화에 효과적이다. 또한, 의미와 가치발견에 중점을 둔 강점 기반 접근을 통해 학습 참여를 증진하고 지속 가능한 학습 환경과 배움을 실현할 수 있다. 이러한 교육적 효과는 긍정적 가 치 탐색의 4D 프로세스를 토대로 한 활동으로 이루어진다. 교육 현장에서 긍정적 가치탐색 4D 프로세스 를 보다 유용하게 활용하기 위해서는 교육목표와 지향하는 역량개발에 따라 4D 프로세스에 적합한 학습 유형 분류와 체계적이고 구조화된 학습모형 개발이 필요하다. 본 연구는 4D 프로세스 기반 4가지 학습유 형을 구조화하여 학습모형을 개발하고 모형타당화를 진행하였다. 4D 프로세스 기반 학습모형 구성요소 도 출은 선행 문헌의 검토와 분석을 통해 이루어졌고, 구성요소의 구조화는 사례연구를 통해 진행하였다. 그 리고 해당 분야 전문가 검토를 통한 타당성 평가를 3차에 걸쳐 실시하였다. Discover, Dream, Design, Destiny 4D 프로세스는 탐색과 발견, 사고와 상상, 공유와 구성, 발표와 실천으로 개선되어 적용되었다. 학습에 적합하도록 보완된 4D 프로세스는 도달할 학습 목표와 개발할 학습자의 역량에 따라 탐구형, 창의 형, 과제해결형, 실천형으로 세분화하여 개발되었다. 개발된 학습모형에서의 학습유형은 다양한 교육 환경 에 맞게 긍정적 가치탐색 활동이 선택적으로 운영될 수 있다는 이점이 있다.

The inseparability, one of service specific characteristics, often makes it necessary and possible for customers to participate in service production and delivery process as partial employees or contributors. As customer participation may enhance or degrade the quality of services and customers’ satisfaction, many researchers have paid much attention to the concept of customer participation. Analogous to the typical classification of service employee behaviors, previous research typically categorized customer participation behaviors into customer participation behaviors and citizenship behaviors. Furthermore, past research showed that both types of customer behaviors significantly affect perceived service quality and satisfaction. However, the many criteria past research has used to classify customer participation behaviors lack conceptual rigor and generalizability beyond the specific types of services for which the criteria have been developed. The lack of conceptual rigor and consistency in classification criteria caused much confusion and incongruencies in empirical findings reported in the current customer participation behavior literature, depending on which specific criteria the researcher choose and on the specific type of service studied. Thus, it is important to develop a classification system of customer participation behaviors which is solid and generalizable to many types of services. This study proposes a customer participation behavior classification system which categorizes customer participation behaviors depending on 1) whether a customer behavior is essential and indispensable in the service production process and/or not and 2) whether a customer behavior is conducted voluntarily or upon requests by service employees. Based on the two criteria, the proposed system identifies five types of customer participation behaviors. Furthermore, this study examines whether the five types of customer participation behaviors affect the two dimensions of perceived service quality - outcome quality and process quality (Grönroos1984) and customers’ satisfaction with service experiences. Data for this study are collected through a survey of adult Korean consumers. Major findings of the study can be summarized as follows. First, increasing the level of each of the five types of customer participation behaviors affects perceived service outcome quality, perceived service process quality, and satisfaction. Second, the relative impact of each type of customer participation behavior varies by the types of participating customer’s personality and depending on whether a service is outcome-oriented or process-oriented type. Finally, the actual impact of each type of participation behaviors on perceived service quality and satisfaction varies according to what customers expect when they perform the behaviors.

이 연구의 목적은 지각 변동을 학습하는 과정에서 나타나는 중학생들의 중간 언어의 유형을 도출하는 것이다. 서울의 한 중학교 2학년 2학급에서 18명의 학생들을 선정하였다. 각 학생들은 총 네 차례에 걸쳐 개별 면담을 실시하였으며, 수집된 자료는 의미 관계와 주제 구조를 중심으로 분석되었다. 연구 결과, 일상 언어를 자원으로 하는 경우, 과학 어휘와 일상 어휘를 병용하는 경우, 그리고 과학 언어를 활용하지만 불충분한 경우와 의미 관계가 부적절한 경우를 합하여 총 8개의 중간 언어 유형이 도출되고 서술되었으며, 이를 바탕으로 조사된 중간언어의 함의를 토의하였다.

Reasonable and reliable assessment method is one of the most important issues in science education, Partial credits method is an effective tool for assessing students' science inquiry problem solving. The purposes of this study were to classify the Problem solving types based on the analysis of the thinking Process, and how much the related science concept and the science process skills were used in solving science inquiry problems, and to describe the possibility and rationality of the assessment method that gives partial credit 128 high school seniors were selected and their answers were analyzed to identify science concepts they used to solve each problem, and the result was used as the criterion in the scientific concept test development. Also, to study the science inquiry problem solving type, 152 high school seniors were selected, and protocols were made from audio-taped data of their problem solving process through a think-aloud method and retrospective interviews. In order to get a raw data needed in statistical comparison of reliability, discrimination and the difficulty of the test and the production of the regression equation that determines the ratio of partial credit, 640 students were selected and they were given a science inquiry problem test, a science process skills test, and a scientific concept test. Research result suggested it is more reasonable and reliable to switch to the assessment method that applies partial credit to different problem solving types based on the analysis of the thinking process in problem solving process, instead of the dichotomous credit method.

The technology for sludge drying using a microwave is a primary process in producing solid refuse fuel in the waste-toresource process. In this paper, the drying efficiency is improved by investigating chamber types such as square and circle with various mechanical conditions such as the magnetron power, the height of microwave irradiation, and the sludge thickness. In identical conditions, the moisture content was generally uniform in the circle chamber due to the uniform distribution of microwave irradiation, and the drying efficiency was higher in the circle chamber compared to the square chamber. In the case of the circle chamber, the drying rate was increased by more than 30% and the energy for sludge drying 507.9 kcal/kg of water was reduced. Hence, the application of a circle chamber should save energy consumption in sludge drying.
