Purpose: To develop a substantive theory that represents hospital nurses' experience on caring for dying patients. Method: Grounded theory method guided the data collection and analysis. A purposeful sample of 15 hospital nurses participated during the period of 2001-2002. The data were collected by semi-structured individual interviews. All interviews were audio taped and transcribed verbatim. Constant comparative analysis was employed to analyze the data. Result: 'Putting oneself into shape while being faithful to feelings and emotions' emerged as the basic social-psychological process. Three different phases were identified: being faithful to own feelings and behaviors; putting oneself into shape; and mourning death. The first phase includes the categories of 'establishing trust relationships' and 'sympathizing with dying patients and their family members.' The second phase consists of 'controlling feelings,' 'adjusting ethical conflicts,' and 'providing best patient-care,' and 'helping family accept the jeath.' And the third phase consists of 'overcoming sadness' and 'releasing other negative feelings.' Conclusion: The result of this study will help health professionals develop efficient support programs that support nurses caring for dying patients in hospitals. Further study needs to be done to verify findings.

Purpose. The purpose of this study was to explore the experiences of gastric cancer couples in Korea and to generate a substantive theory integrating the experiences of gastric cancer survivors and their spouses as a whole. The specific aims of this study were to explore major problems gastric cancer couples faced and how they resolved these problems, focusing on inter-relational dynamics within the couples and on similarities and differences between the couples. Methods. This was a secondary analysis study using grounded theory techniques. The study used the data of 11 married couples which was collected from in-depth interviews from two primary studies. The unit of analysis was dyads of gastric cancer survivors and their spouses. Results. The basic social psychological process that emerged from the analysis was 'taking charge of their health.' Major categories involved in this process were identified as 1) adjusting to new diets, 2) reinforcing physical strength, 3) seeking information, 4) strengthening Ki, 5) lowering life-expectations, and 6) going their separate ways. These six categories represent major strategies in overcoming critical problems that occurred in day-to-day experiences. In terms of the process, the first five categories characterize the earlier stage of the process of 'taking charge of their health,' while 'going their separate ways' indicates the later stage and also the beginning of their separate ways: 'pursuing spiritual life' for the survivors, and 'preparing for the future' for the spouses. Conclusions. The results of this study will help design family care for the people with gastric cancer by providing in-depth understanding and insight on the lives of gastric cancer couples.

Purpose: The purpose of this study was to explore adjustment pattern of illness process of people with hemophilia in Korea. Method: 23 people with hemophilia had participated for this study. The data were collected through in-depth interviews and analyzed using Strauss & Corbin's grounded theory method. Results: 'would be free from' was emerged as a core category and it reflects that all participants wanted to be free from the constraints of the disease. The adjustment process was categorized into two stage, the ‘unstable stage’ and the ‘stable stage’. In the process of 'would be free from' four different patterns were identified: hopelessness type; appreciation type; challenge type; and transcendence type. These types were identified based on the degree of pursuing normal life and managing the disease, and social support. The most frequently occurring type was hopelessness type but the participants of this type suffered the most. The transcendence type was the most ideal type, but it occurred the least. Conclusion: The results of this study indicate that people with hemophilia in Korea still suffer from the disease and they need supports. The results would be useful for health care professionals in establishing education and counseling program for the people with hemophilia.

무한급수 개념은 학부의 전공 수학 교육과정의 중요한 주제이다. 여러 세기 동안 그것은 학습자에게 직관에 반대되는 장애를 제공했을 뿐만 아니라 해석학 연구의 중심적 역할을 해 왔다. 수학의 역사에서 무한급수 개념에 대한 이해가 미적분학 발달의 기초가 되었듯이 현재의 학생들에게 무한급수 개념에 대한 이해는 전공 수학을 학습하는 데 꼭 필요하다. 무한합의 개념을 가진 학생 대부분은 무한급수의 수렴 판정 같은 수학적 내용은 어려워하지 않으나 무한급수 개념을 부분합의 열을 이용해서 구성하는 것은 어려워한다. 이에 본 연구에서는 무한급수 개념을 구성하는 방법을 APOS 이론과 발생적 분해의 관점에서 부분합 스키마를 이용하여 분석하고자 한다. 질적 연구를 통해 급수 개념의 구성 방법을 점검해서 무한급수 지도 개선에 대한 유용한 교육적 시사점을 얻고자 한다.

Purpose: The purpose of this study was to explore how older adults kept their health good at a doctorless farm village. Method: Data was collected through in-depth interviews with 32 participants who were over 65 years old and analyzed in terms of Strauss and Corbin's (1990) grounded theory methodology. Result: The Core Category of health care of older adults was identified as 'enduring physical changes by themselves'. The process of this could be divided into 4 stages: the stage of bearing, the stage of managing daily living activities, the stage of passively collecting information and the stage of minimally utilizing health care services. Older adults accepted the aging process positively but health sources limitation passively, so they managed daily living activities and used natural food for health. In addition, they collected information related to health care and used health care services minimally. Conclusion: We found that participants managed their health passively because of negative attitudes toward active health behaviors of older adults by themselves and the difficulty of access to health care services. Therefore, various community health services for older adults need to be developed to empower older adults in the community.

Factorization asks the recognition of the structure of polynomials, compared to polynomial expansion with process characteristic. Therefore it makes students experience a lot of difficulties. This study aims to figure out causes of the difficulties by identifying students' cognitive characteristics in factorizing in the perspective of 'structure sense'. To do this, we gave six factorizing problems of three types to middle school students and selected six participants as interviewees based on the test results. They were classified into two categories, structure sense and non-structure sense. Through this interview, we figured out the interviewee's cognitive characteristics and the causes of difficulty in the perspective of structure sense. Furthermore, we suggested some didactical implications for encouraging structure sense in factorizing by identifying assistances and obstacles for recognition of structures.

These days are referred to as 'the times of textile fashion,' owing to the emphasis on textile design in the fashion industry. Accordingly, apparel companies have increased their interests in developing new types of textiles to overcome the limits of style and silhouette. Now the ultra-fashion of textile, a new way of process and design development, is given much more attention. A Moire interference pattern has a longer wavy circle of interference, an effect of intensity interference, than one made by piling more than one reflecting plate or transmitting plate. Till now, Moire interference patterns have been used to confirm scientific theory and to measure the structure of a body or a subject in areas such as physics and medical science. Work has also been done on the Moire interference effects on TV screens said to cause dizziness and eye strain. This study focuses on the new types of textiles by creating the appearance of the Moire phenomena. Contrary to the present usual stationary patterns of textiles, it is a varying pattern according to the different gratings, different angles, piling gratings, and the movements of the human bodies. In the preceding study, we observed Moire fringes formed by overlapping two different or same kinds of gratings such as parallel line gratings, square gratings, conic gratings and semicircular gratings and tried to find a promising possibility of new textiles through the method of clothes design simulation.

사용자 중심 디자인(User-Centered Design)은 주어진 환경(Context)에서의 사용자 행동(Activity)을 모델링 하여 사용자가 기능적, 논리적으로 주어진 작업(Task)을 수행해 낼 수 있는 상품의 디자인을 가능케 하는데 크게 기여한 바 있다. 그러나 사용자 중심 디자인은 사용하기 편하고 유용한 측면을 디자인하는 데는 큰 기여를 했지만, 소비자의 감성 및 문화를 고려한 상품 디자인을 개발하는 측면에서는 아직 성공적인 사례를 제시하지 못했다는 비난을 받고 있는 것도 사실이다. 이는 사용자 중심 디자인이 사용자의 요구사항 (기능적인 요구 사항)에만 치중하는 접근법이기 때문으로, 사용 상황이 중요한 공공 시설물이나 기업 소프트웨어의 개발에는 적합하지만 소비자를 직접 대상으로 하는 디지털 컨텐트 및 디지털 가전의 디자인을 위해서는 부족한 면이 없지 않아 있는 것으로 발표되고 있다. Jordan은 이러한 문제법의 해결안을 제시하면서, 사용자 요구사항의 다차원적(개인적, 사회적, 인지적, 물리적) 접근법을 제안하였고, 그것을 Pleasure-based Approach라고 명명하였다. Jordan도 사용자 조사의 중요성은 부각하였지만, 사용자 조사의 결과를 상품 개발에 접목시키기 위한 방안은 제시하고 있지 못했다. 본 논문에서는 Kano의 상품 속성 모형을 도입하여 사용자 조사 방법과 상품 요소 도출과의 연결고리를 발견하고자 하였다. Kano 모델에서는 상품 요소를 크게 기본요소, 퍼포먼스요소, 엑셀런트 요소로 나누어 설명하고 있다. 퍼포먼스 요소는 설문조사와 같이 직접적으로 고객으로부터 얻을 수 있는 요소로 설명하고 있다. 그러나 기본요소 및 엑셀런트 요소는 직접적인 사용자 조사를 통해서 얻을 수 있는 요소가 아니라 고 주장하고 있고, 이런 요소들을 도출하기 위하여 경쟁상품분석, 참여적 소비자 조사 등과 같은 방법이 도입되어야 한다. 고 말하고 있다. 이에 본 연구에서는 '13-18 청소년용 온라인 커뮤니티 컨텐트 개발 프로젝트' 를 중심으로 엑셀런트 요소 및 퍼포먼스 요소를 도출하기 위한 참석 관찰의 프레임 워크를 제시하고, 그 결과를 기능적 요소, 감성적 요소로 정리하여 상품개발에 활용하도록 하였다. 본 연구의 의의는 상품개발에 사용자 조사의 필요성 및 활용도를 실질적인 프로젝트를 통하여 시도해 보았다는 데 있다고 할 수 있겠다.
