  • 이 연구에서는 이미 해결한 단일개념으로만 구성된 복합개념상황에서 학생들의 문제해결력과 정신용량의 관계를 알아보았다. 과학적 개념이나 원리 하나만 알면 풀 수 있는 문제를 단일개념상황으로 정의하였고 단일개념상황을 2개 이상 결합하여 만든 문제를 복합개념상황으로 정의하였다. 청주시 소재 일반계 고등학교 2학년 학생 152명을 대상으로 정신용량에는 유의미한 차이가 나타나지 않았다. 그러나 이미 해결한 단일개념상황들의 결합으로 만들어 전 복합개념상황의 문제해결에 있어서는 정신용량이 작은 집단에서만 실패한 학생들이 나타났으며 문제해결에 실패한 학생들의 정신용량이 문제해결에 성공한 학생들의 정신용량보다 낮았다. 이러한 연구 결과 단일개념상황은 해결할 수 있으면서 이와 관련된 복합개념상황의 해결에 실패한 이유의 하나를 문제해결자의 정신용량이 작기 때문이라고 볼 수 있다.

  • Relaxation technique is an independent nursing intervention used in various stressful situations. The concept of relaxation must be explored for the meaning given by the people in their traditional thought and philosophy. Korean relaxation technique, wanting to become culturally acceptable and effective, is learning to recognize and develop Korean concepts, experiences, and musics of relaxation. This study was aimed at discovering Korean concepts, experiences and musics of relaxation and contributing the development of the relaxation technique for Korean people. The subjects were 59 mursing students, 39 hospitalized patients, 61 housewives, 21 rural residents and 16 researchers. Data were collected from September 4th to October 24th, 1991 by interviews or questionaires. The data analysis was done by qualitative research method, and validity assured by conformation of the concept and category by 2nursing scientists who had written a Master's thesis on the relaxation technique. The results of the study were summerized as follows; 1. The meaning of the relaxation concept; From 298 statements, 107 concepts were extracted and then 5 categories "Physical domain", "Psychological domain", "Complex domain", "Situation", and "environment" were organized. 'Don't have discomforts, 'don't have muscle tension', 'don't have energy(him in Korean)', 'don't have activities' subcategories were included in "Physical domain". 'Don't have anxiey', 'feel good', 'emotional stability', 'don't have wordly thoughts', 'feel one's brain muddled', 'loss of desire' subcategories were included in "physical domain" 'Comfort body and mind', 'don't have tension of body and mind', 'be sagged' 'liveliness of thoughts' subcategories were included in "Complex domain". 'Rest', 'sleep', 'others' subcategories were included in "Situation domain". And 'quite environment' & 'comfortable environment' subcategories were included in "Environmental domain". 2. The experiences of the relaxation; From 151 statements, 59 experiences were extracted. And then 9 categories-at rest after physical activities, after problem solving, fancy, bathing in the bed, situation, rest, particular time, others-were organized. 3. The musics of the relaxation; From 229 statements, 108 musics were extracted. and the 9 categories- Western classical music, semi classical music, Korean song, Korean popular classical music, song, western popular sonhg, hymn, characteristics of music, others - were organized. In conclusion, There are some differences between Korean concepts, experiences and musics of relasation and western concepts, experiences and musics of relaxation.

  • 본 논문은 복소수 개념이 정당화되는 과정에서 실수와 허수 사이의 관계가 어떻게 변화했는지를 살펴보았다. 허수가 처음 등장한 16세기에 수학자들은 현재와 동일하게 허수를 계산할 수 있었지만 허수를 수학적 대상으로 인정하기까지는 200여년의 시간이 필요했다. 수학이 발달하면서 나타나는 새로운 문제 상황이 실수와 허수의 조화를 요구하였고, 그 결과 복소수의 개념이 점차 명확해졌다. 복소수 개념 발달의 역사는 실수와 허수의 대립이 해소되어 실수와 허수를 복소수로 포괄할 수 있는 관점을 찾아가는 과정이었다. 실수와 허수가 어떤 점에서 대립을 하였고, 수학자들은 이러한 대립에 어떻게 대처하였는가에 분석의 초점을 두고, 실수와 허수의 관계를 정립하는 과정에서 나타난 새로운 사고방식이나 관점을 확인하고 그 영향을 살펴본다. 그리고 이러한 분석결과가 보여주는 교육적 함의를 기술하였다.

  • When imaginary numbers were first encountered in the 16th century, mathematicians were able to calculate the imaginary numbers the same as they are today. However, it required 200 years to mathematically acknowledge the existence of imaginary numbers. The new mathematical situation that arose with a development in mathematics required a harmony of real numbers and imaginary numbers. As a result, the concept of complex number became clear. A history behind the development of complex numbers involved a process of determining a comprehensive perspective that ties real numbers and imaginary numbers in a single category, complex numbers. This came after a resolution of conflict between real numbers and imaginary numbers. This study identified the new perspective and way of mathematical thinking emerging from resolving the conflicts. Also educational implications of the analysis were discussed.

  • Because of limited resources of time and information processing capability during abnormal situation, diagnosis is difficult tasks in nuclear power plant (NPP) operators. Moreover since minimizing of adverse consequences according to process abnormalities is vital for the safety of NPP, introducing of diagnosis support systems have particularly emphasized. However, considerable works to develop effective diagnostic support system are not sufficiently fulfilled because of the complexity of NPP is one of the major problems. To cope with this complexity, a lot of model-based diagnosis support systems have considered and implemented worldwide. In this paper, as a prior step to development of model-based diagnosis support systems, primary side of pressurized water reactor is functionally modeled by multilevel flow modeling (MFM) concept. MFM is suitable for complex system modeling and for diagnosis of abnormalities. Furthermore, knowledge-based diagnosis process, of NPP operator could be supported because this diagnosis strategy can represent operator's one.

  • Wearable smart products contributed to expand the concept of modern clothing in terms of closer communication between wearers and the surrounding environment. This study investigated the concept of wearable smart actuators and characteristics of actuating feedback. The representative product development trends over the past 10 years are examined based on the method of actuating feedback. A first keyword search from Naver and Google reused to select the final 58 products based on the second key keyword actuating feedback. The wearable smart actuator system works in a similar way to a human body system such as those of the information processing process. Actuating feedback is delivered directly to the user as the last signal of the system, which has visual, auditory and tactile feedback. It works in complex at the device to be delivered to the user. Actuator feedback is divided into three types of active and passive, depending on the user situation, the overall purpose of the product, the collected information, and the device dependency. Active actuating feedback determines and actuates the situation on behalf of the user when the user is in an emergency or a disability situation. Passive actuating feedback plays a role in environmental monitoring to help in a healthy daily life.

  • Modernism in architecture is a very complex and contradictory phenomena. So much so that it has been defined in various ways throughout the history, depending on one's position in the cultural and historical circumstances. It is thus necessary to map out the various concepts of modernism and their relationships in order to have a more comprehensive understanding of modern architecture. This paper attempts to define the various positions as functionalism, formalism and artistic avant-gardism, and to trace their history from the early twentieth century to the present. The change of the concept of modernism from functionalism to artistic avant-gardism seems a logical process in the history of western modem culture. The tendency of contemporary architecture to be more abstract and self referential artistic practice reflects the fragmentation of modern culture and the separation of art and technology. The validity of this position, of course, depends on how one evaluates the role of modern art in the situation of modern culture. It could be viewed either negatively or positively. However, this position is problematic in that it disregards the fundamental differences between architecture and other arts and distanced architecture farther from its material base. Given this historical perspective on the concept of modernism, modernism in Korea should not viewed simply identical to the western modernism, nor should western modernism be imported uncritically. The characteristics of her modernization and their differences from the west should be considered, along with the different status and role of architecture in korean modern society.
