환경색채문제는 관심은 상당히 고조되어 있으나 실제 이용할 수 있는 설계기법이나 체계적인 연구성과가 미약하여 설계자 또는 관에서 설계나 행정의 준거로 삼을 만한 자료가 태무한 실정이고 이런 상황에서 본고는 건축과 도시색채의 일반적 계획원리와 색채계획과 설계의 과정을 약술함으로써 문제제기를 겸하여 건축설계 또는 도시설계자들의 참고자료에 보탬이 되게 하려는 것이다. 앞으로 이 분야의 연구와 자료축적이 꾸준히 이루어짐으로써 합리적인 이론과 실용적인 기법이 정립되는 것이 건축계의 또 하나의 과제일 것이다.

Problem posing in school mathematics is generally regarded to make a new problem from contexts, information, and experiences relevant to realistic or mathematical situations. Also, it is to reconstruct a similar or more complicated new problem based on an original problem. The former is called as problem generation and the latter is as problem reformulation. The purpose of this study was to explore the co-relation between problem generation and problem reformulation, and the educational effectiveness of each problem posing. For this purpose, on the subject of 33 pre-service secondary school teachers, this study developed two types of problem posing activities. The one was executed as the procedures of [problem generation${\rightarrow}$solving a self-generated problem${\rightarrow}$reformulation of the problem], and the other was done as the procedures of [problem generation${\rightarrow}$solving the most often generated problem${\rightarrow}$reformulation of the problem]. The intent of the former activity was to lead students' maintaining the ability to deal with the problem generation and reformulation for themselves. Furthermore, through the latter one, they were led to have peers' thinking patterns and typical tendency on problem generation and reformulation according to the instructor(the researcher)'s guidance. After these activities, the subject(33 pre-service teachers) was responded in the survey. The information on the survey is consisted of mathematical difficulties and interests, cognitive and affective domains, merits and demerits, and application to the instruction and assessment situations in math class. According to the results of this study, problem generation would be geared to understand mathematical concepts and also problem reformulation would enhance problem solving ability. And it is shown that accomplishing the second activity of problem posing be more efficient than doing the first activity in math class.

Scientific literacy has long been as one of the key goals of science education, and using scientific inquiry in school science has became an important objective to be achieved. The processes of scientific inquiry consist of proposing/developing inquiry question, designing and conducting investigation, collecting, analyzing and interpreting data, and communicating the results. However, most students experience mainly collecting and transforming data in inquiry processes in science class and they are barely exposed to the opportunities of proposing/developing inquiry questions. Middle school earth science preservice teachers participated in this study (N=36) and their abilities of developing inquiry questions were surveyed. Participants' abilities of developing inquiry questions were investigated whether they were enhanced with activities using the Inquiry Questions Development Guide (IQDG). Also, this study was interested in whether there was any relationship between abilities of developing inquiry questions and designing inquiry investigation. The results of this study were as follows; first, the level and preciseness of inquiry questions and its preciseness developed by participating teachers were enhanced after experiencing IQDG. In addition, teachers' dominating inquiry question-types were two: one is a 'relationship-inquiry question' in which students could discover the relationship between results found in the given experimental situations and the other one is a 'why-how inquiry problem' in which students could explore a cause or a process that results in the outcomes. Finally, the higher level of and preciseness the of inquiry questions were identified as an important factor the determined teachers' abilities of designing more logical investigation. A process of proposing/developing inquiry question was identified as one of the most important processes contributing to a success of scientific inquiry investigation.

In personalized marketing, it is important to maximize customer satisfaction and marketing efficiency. As personalized campaigns are frequently performed, several campaigns are frequently run simultaneously. The multiple recommendation problem occurs when we perform several personalized campaigns simultaneously. This implies that some customers may be bombarded with a considerable number of campaigns. We raise this issue and formulate the multi-campaign assignment problem to solve the issue. We propose dynamic programming method and various heuristic algorithms for solving the problem. With field data, we also present experimental results to verify the importance of the problem formulation and the effectiveness of the proposed algorithms.

핵폐기물 지하처분, 지열개발, 지하 환경의 안전과 제어 등과 관련된 문제에 있어서 암석 및 암반의 역학적 거동 외에 열·수리·화학적 상호작용에 대한 이해가 필요하다. 이미 전세계적으로 국가별로 혹은 공동연구를 통하여 열·수리·역학적 상호작용에 관하여 많은 연구가 진행되었으며 최근 화학적 상호작용에 대한 문제가 추가적으로 제기되고 있다. 특히 장기간의 지하 환경의 안정성에 미치는 중요한 요소로 크립현상과 열·수리 화학적 상호작용 연구에 대한 필요성이 제기된 바 있다. 이 중 열·역학적 상호작용에 대해서는 현장문제에 적용 가능한 만은 연구결과가 제시된 바 있으나 기타 상호작용에 대해서는 다양한시험방법과모델링으로 인하여 아직가지 통일된 의견이 제시된 바 없다. 제 2주제에는 총 92편의 논문이 접수되었으며, 이 논문들의 내용, 성격, 해석방법 등을 간략히 정리하였다.

오늘날 지식과 기술과 경영은 세계적 경쟁질서의 중심에 있다. 대학도 이제 국가 내에서의 경쟁에서 국제적 경쟁의 시대로 접어들었다. '대학의 정신과 이념 회복'은 이러한 상황에서 제기된 문제라고 본다.
