The research reviews the logical approach based on the creative thoughts. The two logical approaches, including deductive convergent and inductive divergent are discussed with why-why techniques and how-how techniques. While the deductive thinking is vertical logic for interconnected hierarchical and deep domains, the inducive thinking is horizontal logic for mutually exclusive and collectively exhausted frameworks. The creative thinking comes from the reversing the logic and lessening the premise of convergent and divergent approaches.

본 연구의 목적은 문화성향과 인지양식의 조합 조건에 따라 전역/국소처리에서 어떠한 차이가 관찰되는지 검토하는 것이다. 이를 위해 Singelis 등[1]의 문화성향 질문지(INDCOL)와 Choi 등[2]의 인지양식 질문지(AHS)에 기초하여 실험참가자들의 네 유형의 문화성향(개인주의, 집단주의, 수평 성향 및 수직 성향) 점수와 인지양식 유형(분석적 또는 종합적 사고)에 따라 집단을 분류하고, 복합자극 유형(화살표로 구성된 복합도형 또는 알파벳 낱자로 구성된 복합문자)에 대한 전역/국소처리에서의 반응시간과 오반응율에서의 차이를 집단에 따라 비교하였다. 본 연구의 결과를 요약하면 다음과 같다. (1) 전반적으로 복합문자보다는 복합도형의 경우, 그리고 국소처리 조건보다는 전역처리 조건에서의 반응시간이 더 빨랐다. (2) 개인주의 성향과 수평 성향이 인지양식 유형과 각각 결합된 경우 전역/국소처리에서 집단간 반응시간 차이는 발견되지 않았으나, (3) 집단주의 성향과 수직 성향이 인지양식과 각각 결합된 집단의 경우에는 전역/국소처리에 대한 문화성향과 인지양식의 유의한 상호작용 효과가 모두 관찰되었다. 이러한 결과는 개인주의 성향 또는 수평 성향보다는 집단주의 성향 또는 수직 성향이 종합적 사고 유형과 결합될 때 더 큰 전역선행성 효과를 가져 온다는 것을 시사한다.

한국의 대학생을 대상으로 문화성향(개인주의-집단주의, 또는 수평적-수직적 사고)과 종결욕구 수준(저-고집단)의 조합에 따른 틀효과에서의 차이를 살펴보았다. 이를 위해 Singelis 등[1]의 INDCOL 척도와 이성수[2]의 NFC 척도를 사용하여 문화성향과 종결욕구 수준에 따라 집단을 분류한 후, 다섯 가지의 의사결정 시나리오에 대한 위험추구와 위험회피의 틀효과 차이를 비교하였다. 본 연구의 결과를 요약하면 다음과 같다. (1) 이득틀 조건에서는 위험회피 대안의 선택 비율이, 반면 손실틀 조건에서는 위험추구 대안의 선택 비율이 상대적으로 더 높았다. (2) 두 가지 문화성향(개인주의-집단주의, 수평적-수직적 사고성향)에 따른 틀효과 차이는 각각 유의하지 않았으나, 종결욕구가 높은 집단은 종결욕구가 낮은 집단에 비해 손실틀 조건에서 위험추구 대안에 대해 상대적으로 더 높은 선호도를 보였다. 마지막으로 (3) 개인주의 문화성향과 수평적 사고성향에서는 종결욕구 수준에 따른 틀효과 차이가 유의하지 않았으나, 집단주의 문화성향과 수직적 사고성향에서는 종결욕구 수준에 따른 틀효과의 차이가 유의하였다. 즉, 틀효과에 대한 집단주의 문화성향과 수직적 사고성향의 영향은 종결욕구 수준이 낮은 집단보다는 높은 집단에서만 관찰되었다.

The purpose of this paper is to contribute to the dialogue about the notion of advanced mathematical thinking by offering an alternative characterization for this idea, namely advancing mathematical activity. We use the term advancing (versus advanced) because we emphasize the progression and evolution of students' reasoning in relation to their previous activity. We also use the term activity, rather than thinking. This shift in language reflects our characterization of progression in mathematical thinking as acts of participation in a variety of different socially or culturally situated mathematical practices. We emphasize for these practices the changing nature of student' mathematical activity and frame the process of progression in terms of multiple layers of horizontal and vertical mathematizing.

This article provides how to implement the use of Realistic Mathematics Education (RME) in a teaching a function at a school to improve students' mathematization for their mathematical thinking using technology, This study was planed to get research results using the mixed methodology with quantitative and qualitative methodologies. 120 middle school students participated in the study to bring us data about their mathematical achievement and disposition. Through the data analysis used ANCOVA, the students with the experiment of the mathematization and technology excelled the other groups of students who were not provided with technology or both of them. In analysis of the questions of the achievement test, the problems for vertical mathematization were presented harder for the students than the other problems for horizontal and applicative mathematization. The technology environment might have helped students manipulate the application of real-life problems easier. This means that teachers can put more careful assignment on vertical mathematization using technology. We also explored that learning and teaching under RME using technology encouraged students to refine and develop their informal functional concept and pursue higher thinking of formalization. The study results in a lot of resources for teachers to use into their teaching mathematics for improving students' mathematical thinking.

As the 7th mathematics curriculum reform in Korea was implemented with its goal based on Freudenthal's perspectives on mathematization theory, the research on the effect of mathematization has been become more significant. The purpose of this thesis is not only to find whether this foreign theory would be also applied effectively into our educational practice in Korea, but also to investigate how much important role teachers should play in their teaching students, in order that students accomplish the process of mathematization more effectively. Two case studies were carried out with two groups of middle-school students using qualitative-research method with the research instrument designed by the researcher. It was found that we could get the possibility of being able to apply effectively this theory even to our educational practice since the students engaged in their mathematization using the horizontal mathematization and the vertical mathematization in geometry. Also, it was mentioned that teachers' role was so important in guiding students' processes of mathematization, although mathematization is the teaching-learning theory, stimulating students' activities. Since the Freudenthal's mathematization applied in the thesis is so meaningful in our educational practice, we need more various research about this theory that helps students develope their mathematical thinking.

This study was carried out to find out the effect of conflict between profession groups within medical institution. For the purpose, the questionnaire-based research was done with 605 persons consisting of specialists, residents, nurses, radiologic technicians, clinicopatholigic technicians, health record administrator, administrative employees who are working in a university hospital located in Taegu City from February 15, 1997 to March 2, 1997. The results of the study were summarized as follows. The subject profession group against which each profession group feels the most conflict in interprofession mutual recognition relation was found out as follows; Specialists(34%) against colleague specialists, residents(54.0%) against nurses, nurses(54.8%) against residents, radiologic technicians(44.0%) against residents, and clinicopathologic technicians(34.5%) against nurses, while it was shown that health record administrator felt even conflict against residents, nurses and administrative employees and administrative employees(48.1) did against nurses. Most employee group answered that medical specialists have a one-sided and individual attitude toward all affairs, while both medical specialists and administrative employees of hospital answered that nurses are one-sided. It was shown among such groups that radiologic technicians' conflict results from their thinking which mutual dependence and cooperation are lowest while individual difference is highest, clinicopatholigic technicians' conflict from the problem in mutual communication, medical specialists' conflict from difference in goals greater than other group, respectively lower than other group. The rate of vertical conflict between groups was highest for the health record administrators and then for the radiological technicians, while it was lowest for the medical specialists and then for the nurses. In addition, the rate of horizontal conflict was high for both medical specialists and nurses, but it was low for the health record administrations and clinicopathological technicians. The group with the highest job satisfaction was the medical specialists and nurses, and the group with the highest involvement in organization was the medical specialists and administrative employees. Also it was shown that both medical specialists and clinicopathological technicians show a favorable attitude toward patients. Factors having an effect on the vertical conflict included difference in goals, cooperation within group and leadership. It was shown among those factors, however, that only the leadership has an effect on all the groups evenly. The horizontal conflict was influenced by such factors as educational level, mutual dependence, difference in goals, cooperation within group, and individual difference, when an important factor was the difference in goals for all the groups. Their attitude toward patients was influenced by the vertical conflict and age, but the vertical conflict was the most significant factor for the medical specialists. In conclusion, it is required to control properly the conflict between employees as well as between profession group and to execute good leadership, so as to improve patients' satisfaction which is the key goal of hospital.

Conventionally, ornament has developed around linear thinking based on Euclidean geometry, and been explained as simple and lucid natural Euclidean geometrical phenomena. The modular arrangement with vertical, horizontal and diagonal grids has been an organizing principle of classical ornament, but in digital era ornament is found not to be explained only with the principle of traditional arrangement due to the seemingly irregular complex forms. In that sense, this study presents the concept of digital ornament and examined the backgrounds of ornament in digital age, that are complex system and non-Euclidean geometry. Accordingly, the present study takes an approach by dividing new formal types of ornament into algorithmic form, hybrid form and dynamic form to find out a principle of pattern organization. Lately, architects who actively use computer for their architectural designs take the algorithmic strategies in nature and create various and complex patterns by simple rules. The patterns are not the repetition of the same, but the production of singularities. In addition, hybrid form by morphing shows a topologically flexible evolutionary transformation, and is used to create in-between transitional shapes from the source to target. Finally, the patterns by the interaction between the system components which are corresponded to the embedded forces emerge from dynamic simulation of the natural environment. Rather than objects itself, focus is given to the process of generating forms, and the ornamental patterns as the revelation of such implicit order provide not just the formal beauty but also spatial pathways for lights and air, maximizing the effects of lights.
