New design concept of Reactor Coolant System (RCS) including a reactor assembly for the SMR is introduced in this work. An exploration of new type of reactor that is advanced from proposed SMRs is performed by using systems engineering approach. In this point of view project structured on three main phases; needs analysis (NA), concept exploration (CE), and concept definition (CD). Main objectives as an output of the CE stage are a small size, low cost, shortening the schedule, and enhancing safety. The SMRs usually have a small size requirement. In order to meet the size requirement and to achieve a productivity, in other words, easiness to manufacture, this paper suggests an integrated PWR design concept through researching predecessors. Although the integrated PWR concept provides many advantages, it has disadvantages that composite of maintenance and a low availability problem. Therefore, this paper comes up with a run-to-fail design concept based on modular design to address the maintenance problem and to maximize the availability of SMRs as well as to be compatible with the overall-SMRs including Barge Mounted(BM)type.

Health, a major concept in nursing, has not yet consistent or agreed upon definition. Although effective health care depends on clear communication between health care provider and client clear definition of health would enhance the promotion of quality in health care. There are no agreed definitions or criteria for overall health. An essentialstep would seem to be to determine commonly held meaning about the concept of health. Therefore, the study was aimed at identifying the Adult's perceptions of health concept. The subject's consisting of 312 adults, who were sampled through area sampling from May 10 to May 30,1988. The instruments used for this study were Health Conception Scale, which was developed by Smith, Laffrey's revised and tested its reliability. The data was Analyzed by S.P.S.S. program and the results were as follows ; 1. The results of the reliability test for content of health concept was $\alpha$＝.87. 2. The respondents perception of Health Meaning were inclined to emphasize the functional / role performance dimension rather than clinical dimension. 3. The perceptual level of health concept was proved to be significantly different by the variable : age, sex, religion, area marital status. In conclusion, adult's perception of Health Concept is revealed that functional and role performance dimension is more important than other dimensions. Futher study is necessary to clarify the structure of functional, adaptive, eudaimonistic dimension and systematic study with subculture will be and repetitive verification and modification of this tool is demanded.

The purpose of this study is to investigate the degree of concept understanding on the stratum for elementary school students. For this objective, questions on the stratum concept were developed, and concept survey was conducted for random sampling of $5^{th}$ and $6^{th}$ grade 536 students. As a result, students chosen correct answers of the average 57.4% for 16 questions. Below the average rate of correct answers in each domain were 1 question in the definition of the stratum, 3 questions in formation of the stratum, and 4 questions in features of the stratum. Especially, the percentage of correct answers were appeared in lowly that the difference between the visible side and non visible side on the stratum, the definition and formation process of a fault and the main cause of the stratum's exposure. Also, between the residence, grade, and gender of students, there were significant differences in 2 questions, 7 questions, and 1 questions, respectively. Therefore, many elementary school students do not have high understanding about the stratum concept. Through the results of this study, it can be contributed to find an efficient ways as a basic data for modify misconceptions of the stratum to the scientific concept.

Purpose: This research is a descriptive study to explore "patient respect" in nursing. Respect was analyzed as a concept in the domain of the patient. The Hybrid Model suggested by Schwartz-Barcott and Kim was used in this study. Method: For the theoretical phase, nursing and other literature were reviewed to analyze attributes and develop a working definition of the concept, respect. For the fieldwork phase, four subjects in two general hospitals in Seoul participated. With the participants' permission, the data was collected between January and April, 2002, through in-depth interview and participant observation. The data analysis progressed at the same time as the fieldwork. Data analysis proceeded according to the analysis method of Strauss and Corbin. Result: The final attributes of patient respect are suggested by consideration, recognition, cordial treatment, concern, honesty, acceptance. The final definition of patient respect as a concept in the domain the of patient is suggested by "Patient respect is that the patient is recognized as an individual with worth and is accepted, and considered to be that kind of an individual person. In addition, the patient is recognized to be an independent person and is treated with concern and honesty." Conclusion: The results of the analyses is helpful in integrating into a comprehensive description of the concept, Patient Respect.

본 연구는 그래핑 계산기를 이용한 함수학습이 학생의 개념이미지의 개념정의로의 변화에 어떠한 영향을 미치고 학생들은 그래프를 통해 어떤 정보를 얻어내며 그래프와 수식사이를 어떤 과정을 통해 이해하는가를 정성연구를 통해 조사하였다. 그 결과 첫째, 함수에 대한 사전학습이 없었던 학생은 그래핑 계산기 환경에서 많은 정보를 얻으면서 개념정의를 가지게 되었고 스스로 탐구하는 학습을 하였다. 반면 사전 학습이 있었던 학생은 함수에 대해 많은 개념이미지를 가지고 있어서 그래핑 계산기의 사용을 불필요하게 생각하였고 그 효과도 다른 학생에 비해 미비하였다. 세 학생 모두 그래프를 비교하는 문제와 평행이동을 조사하는 문제에서는 계산기를 유용하게 사용하면서 학습해나갔다. 그래프처럼 시각적인 것을 통한 학습이 대수식을 통한 학습보다 함수의 변화 등 역동적인 학습을 통해 개념정의로 접근이 용이하였으며 학생들의 학습과정에서 그래핑 계산기의 역할에 따른 학습모델을 제시 가능하였다.

A terror is more grave than any other one in behavior, and the criminals have to be punished so much and be discriminated from other ones, too. So, a concept of general crime and terror has to be defined. It is finished in the academic area to some extent, but, it is not sufficient in lawful area so much. Afterwards, it is necessary to establish counter-terror protection laws regulating terror crimes directly. In addition, it is necessary to define concretely and clearly the terror activity and deduce the definition of terrorism.

The purpose of this study is to identify the legal definition and usage of cultural property term related to the architecture within the cultural property-related legal system and general legal system, and to present proper terminology and specific concepts that can be used for the architecture as cultural properties. In the current cultural property legislative system, terms about the architecture are diverse and obscure, and the definition of each term is different from the concept in the general legal system. In this context, this study presented the terminology of 'the architectural heritage' as 'a cultural property by construction act' to cover whole cultural properties related to Korean architecture. And the conceptual scope of the architectural heritage is divided into the technology and the performer related to the act, the record and the building related to the product. and Each concept needs to be specifically tailored to its object and scope. Systematic definition of terms for cultural properties related the architecture can positively influence systematization of cultural property preservation and management as well as empirical research and education on Korean architecture.

Objectives Although the word Zheng (證) is widely used basic term in nowaday's East Asian traditional medicine, it's definition can't be found in ancient texts before 20th century, and the history in which that term got general meaning in public, have not been clearly introduced. So the present author show the way Zheng confirm it's modern implication. Methods To search the books that contain any contents on Zheng's definition, the author mainly used the electronic texts of Super Star Reader (超星閱讀器). To search modern study article on Zheng's definition, the author used China National Knowledge Infrastructure (www.cnki.net). Results The present study shows that : although Treatments according to disease Pattern Identification (辨證施治) have been prominent treatment modality in East Asian traditional medicine, the general definition of disease Pattern (證) was given in late 20th century. Especially from 1955 to 1965, some major scholars like Ren Ying Qiu (任應秋), Zhu Yan (朱顔), Qin Bo Wei (秦伯未) and Jiang Jian Fu (蔣見復) did important roles in it's concept creation. Conclusions Modern concept of Zheng (證) was defined in late 20th century.

사용자 경험(UX)이라는 개념이 기존 사용성 중심의 패러다임에 대한 대안으로서 학계와 업계의 지대한 관심을 받고 있다. 그러나 대다수의 경우 사용자 경험에 대한 명확한 정의를 생략하거나 협소한 유사 개념과 혼용하고 있다. 따라서 본 연구에서는 존 듀이의 실용주의 경험 철학에 기반하여 HCI에서의 사용자 경험을 개념적으로 정의하고 최적 사용자 경험의 요건을 제시하였다. 또한 HCI 환경의 변화로 사용자의 경험이 개인적 수준을 넘어 사회적으로 공유되고 있는데, 기존의 UX 개념으로는 이러한 사용자 경험을 설명하기 어렵다. 따라서 본 연구에서는 사회 심리학의 공유 인지 연구를 바탕으로, 사용자 경험을 넘어선 사용자의 공동 경험 개념을 설명하고 사용자의 공동 경험감(CX)이라는 개념의 정의와 조건을 제시하였다.
