  • urpose : The purpose of this study was to evaluate the US II plus/GS II Osstem$^{(R)}$ implants through the study for the clinical success rate during the installation of the Osstem¢Á implants after bone graft. Materials and Methods : This study was researched in the 4 medical institutions: Chonnam National University, Chosun University, Bundang Seoul National University Hospital, and FM dental clinic from May, 2002 to September, 2009. Based on the total number of 60 patients whose treatment was the installation of the US II plus/GS II Osstem¢Á implants after bone graft, we evaluated success rate of implants. We analysis the distribution of patient's age and gender, edentulous area, bone type, fixture length and diameter, installation and loading time, donor site, bone graft material and method, antagonistic teeth, and survival and success rate. From these analyses we got the following results. Results : 1. In this study, the total number of patients who have been installed with US II plus implant was 27, and total of 52 implants were installed. The average age was 38.9, with 16 male, and 11 female patients. 2. The total number of patients who have been installed with GS II implant was 33, and total of 54 implants were installed. The average age was 49.7, with 24 male, and 9 female patients. 3. As for bone graft method, either autogenous bone or a mix of autogenous and heterogenous bone was used(88.4%) for US II plus. Chin, iliac, and Maxillary tuberosity were the donor sites for autogenous bone graft, and onlay method of bone graft was performed. 4. Allogenic bone or a mix of autogenous and heterogenous bone was used(77.8%) for GS II. Chin, ramus, and tibia were the donor sites for autogenous bone graft, and GBR method of bone graft was performed. 5. The duration from the installation of implants to setting of final prosthesis was average of 16 months and 10 months for US II plus and GS II respectively. Also, the final follow up period was average of 31 months and 28 months respectively. During this period, one GS II implant was removed from 1 patient due to failure of early osteointegration. 6. The survival rates were 100% and 98.1%, and success rates were 94.2% and 94.4% for US II plus and GS II implant respectively. Conclusion : On the evaluation of our clinical study, both US II plus and GS II Osstem¢Á implants showed the excellent clinical results after bone graft.

  • Against the backdrop of the increasing trend towards economic globalisation, many international firms are indicating that decisions on how to enter foreign markets remains one of the key strategic challenges confronting them. Despite the rich body of literature on the topic, the fact that these challenges have continued to dominate global marketing strategy discourses point to someevident lacunae. Accordingly, this paper considers the variables, categorised in terms of firm contexts (standardisation, market research, competition, structure, competitive advantage) and host country-contexts (economic development, cultural differences, regulation and political risk), which influence the degree of involvement of UK companies in overseas markets. Following hypotheses were drawn from literature review: H1: The greater the level of competition, the higher the degree of involvement in the overseas market. H2: The more centralised the firm's organisation structure, the higher the degree of involvement in the overseas market. H3a: The adoption of a low cost-approach to competitive advantage will lead to a higher degree of involvement. H3b: The adoption of an innovation-approach to competitive advantage will lead to a higher degree of involvement. H3c: The adoption of a market research approach to competitive advantages will lead to a higher degree of involvement. H3d: The adoption of a breadth of strategic target-approach to competitive advantage will lead to a lower degree of involvement. H4: The higher the degree of standardisation of the international marketing mix the higher the degree of involvement. H5: The greater the degree of economic development in the host market, the higher the degree of involvement. H6: The greater the cultural differences between home and host countries, the lower the degree of involvement. H7: The greater the difference in regulations between the home country and the host country, the lower the degree of involvement. H8: The higher the political risk in the host country, the lower the degree of involvement. A questionnaire instrument was constructed using, wherever possible, validated measures of the concepts to serve the aims of this study. Following two sets of mailings, 112 usable completed questionnaires were returned. Correlation analysis and multiple regression analysis were used to analyze data. Statistically, the paper suggests that factors relating to the level of competition, competitive advantages and economic development are strong in influencing foreign market involvements. On the other hand, unexpectedly, cultural factors (especially individualism/collectivism and low and high power distance dimensions) proved to have weak moderating effects. The reason for this, in part, is due to the pervading forces of globalisation and the attendant effect on global marketing. This paper has contributed to the general literature in a way that point to two mainimplications. First, with respect to research on national systems, the study may hold out some important lessons especially for developing nations. Most of these nations are known to be actively seeking to understand what it takes to attract foreign direct investment, expand domestic market and move their economies from the margin to the mainstream global economy. Second, it should be realised that competitive conditions remain in constant flux (even in mature industries and mature economies). This implies that a range of home country factors may be as important as host country factors in explaining firms' strategic moves and the degree of foreign market involvement. Further research can consider the impact of the home country environment on foreign market involvement decisions. Such an investigation will potentially provide further perspectives not only on the influence of national origin but also how home country effects are confounded with industry effects.

  • A considerable change of the Korean nursing system has been made during the last decade not only in its philosophy but also in its function and structure to meet political and scientific need of the modern society. The main purpose of this study is to develope the new concept of comprehensive nursing care, both its Philosophy and ethics, as the basic of modern clinical nursing theory and practice. Comprehensive nursing care is the concept of human centered nursing care, and it helps a man to meet the basic physical, psychological, environmental, socioeconomic and teaching needs. It also helps him to help himself to meet these needs. This concept starts from the individualized nursing care and its ultimate goal is to improve a man to have a better position in his own community so that he may able to have a meaningful life. To accomplish this goal, an individualized nursing care plan as a nursing diagnosis and problem solving method should be set up for different patients with similar diagnosis to meet their needs, because each patient has a different social background. from this viewpoint, nursing is a science as well as abstruse humanity. The performance of comprehensive nursing care is a goal and issue of modern clinical nursing care. If nursing is a science and a profession for man, it should have ethics which recognize the dignity of man and offers infinite service voluntarily, and should be able to show leadership in carrying out the nursing responsibility. This leadership finds a person's potential and encourages him to utilize it. Such concepts should develop into a nursing ideology and this ideology should become a priority in comprehensive nursing care. The following statements are the conclusion of this study. 1) Modern nursing has been developed from disease centered nursing care to comprehensive nursing care based on humanity. The primary principle of nursing was to assist in the treatment of disease, but it has been changed to the professional nursing system independently. 2) The concept of nursing is one of continuous or endless scope of dispersion. It proves that nursing is grasping the professional responsibility to be able to coordinate scientific principles Patient health problems are according to scientific principles rather than adhering to nursing technical discipline as a daily work. 3) In chapter I and Ⅱ, the philosophy and ideology of nursing have been discussed and the flow of concept of clinical nursing and the rate of progress which emerges from naturalizing performance of the concept of comprehensive nursing in clinical nursing studied. The discussion developed the theory that a nurse should be to embody nursing ideas and objectives by establishing definite conviction of professions and study. 4) In chapter lil, nursing planning based on nursing diagnosis as a method to attain ideal nursing care for humanity with a definite idea of establishing philosophy of nursing was presented. 5) From the result of survey on patient needs about treatment and nursing, it was observed that all patient had emotional stress from unknown factors. Therefore it was concluded that nurses should not only educate the patient but also give them the opportunity to communicate freely their needs and anxieties. Furthermore complaints and doubts of the patient should be carefully noted and must be considered to meet these needs. 6) Patient teaching is the most important part of comprehensive nursing care. In chapter, Ⅲ, the important of patient teaching was emphasized by demonstrating the effect of patient teaching for diabetic patient. 7) In Chapter Ⅳ, from the result of the study on nurses attitudes to comprehensive nursing care, it was pointed that the evolution of nursing education and the establishment of a complete concept and value of comprehensive nursing was necessary.

  • This study identified the impact of childhood cancer on the Korean family. The purpose was to contribute knowledge for family nursing and pediatric hospice care practice with sick children and their families. This descriptive study was conducted during a 6 month period with children who were being treated for cancer at six university hospitals in Seoul. The data were gathered from members of 68 families ; 24(Group A), with a child newly diagnosed with cancer : 27(Group B), with a child under treatment and without complications, and 17 (Group C), with a child in relapse. Medical records, structured questionnaires and interviews were used for data collection. The questionnaires and interview schedules had been used previously in Martinson's research in the USA and China. The findings, conclusions, and suggestions are as follows. 1. The impact of childhood cancer on the family. Members of the family experienced fear, helplessness, guilty feelings, and anger at the time of the initial diagnosis and at relapse. Mothers complained of headache, anorexia and poor appetite, weight loss, sleep disturbance, and bad dreams. Many of the fathers either lost or changed jobs, and all working mothers stopped working. Half the parents reported changes in their marital relationships such as frequent quarrels but also stronger unity. Family members perceived cancer as the most frightening disease. Change in their world view was expressed as living on faith understanding suffering, determining to live a better life, wanting to live an upright life and valuing health as the most important. Religious activities are found most helpful through this difficult experience. Financial debt due to the treatment and care of the sick child, burdened 22 families. The above mentioned impact was most evidant in Group B(those presently undergoing treatment) and Group C(those in relapse). Findings indicate that nursing care should embrace the family of a child who is being treated for cancer. 2. Characteristics of the child with cancer The majority of the children in this sample had a diagnosis of leukemia. Their mean age was 6.8 and the ratio of boys to girls was 1.12 ; 1. The mean hospitalization frequency was 13.5 times and the mean duration of illness was 16.8 months. Most of 1.he children perceived cancer as the most frightening disease ; 32.7% of the children described their sickness as serious. Children in Group C were hospitalized more frequently, stayed in hospital for longer periods, and expressed their sickness as quite serious more often than the other two groups. These findings indicate how much comprehensive pediatric hospice nursing care services are needed along with relevant research and nursing education. 3. Characteristics of the families. The mean age of the father was 39.5 and the mother, 36,6 ; they are in their most productive life period. Mothers especially expressed feelings of financial uneasiness and powerlessness about giving up their jobs, and guilty feelings for not providing enough care and concern to other children due to taking care of the sick one. The burden of caring for the sick child can bring negative changes in family dynamics which they think provoke potential health problems in members of the family These findings suggest a need for nursing support and counselling resources. Findings also suggest the need for ethical inquiry about such questions as who should give information to the child in regard to diagnosis and prognosis, when, and how. Other suggestions included : 1) Quality health care for childhood cancer such as home care and pediatric hospice programs should be established. 2) Special and practical consideration for long-term patients should be made in the present insurance coverage. The reimbursement period for long-term patients should be lengthened. 3) Further in-depth qualitative studies are needed. 4) Education programs including guided practice experience for pediatric hospice care practitioners are needed.

  • Care is a central concept of nursing. Nursing would not exist without caring. Care and quality of life are closely related. Human behavior is a manifestation of culture. We can say that caring and nursing care are expression of culture. The nurse must understand the relationship of culture with care for ensure quality nursing care. But knowledge of cultural factors in nursing is not well developed. Time and in - depth study are needed to find meaningful relationships between culture and care. Nurses recognized the importance of culturally appropriate nursing There are two care systems in culturally based nursing. The folk care system and the professional nursing care system. The folk care system existed long before the professional nursing care system was introduced into this culture. If the discrepancy between these two care systems is great, the client may receive inappropriate nursing care. Culture and subcaltures are diverse and dynamic in nature. Nurses need to know the caring behaviors, patterns, and their meaning in their own culture. In Korea we have taken some first step to study cultural nursing phenomena. It is not our intent necessarily to return to the past and develop a nationalistic of nursing, but to identify the core of traditional caring and relate that to professional nursing care. Our Assumptions are as follows : 1) Care is essential for human growth, well being and survial. 2) 7here are diverse and universal forma, expressions, patterns, and processes of human care that exist transcul - turally. 3) The behaviors and functions of caring differ according to the social structure of each culture. 4) Cultures have folk and professional care values, beliefs, and practices. To promote the quality of nursing care we must understand the folk care value, beliefs, and practices. We undertook this study to understand caring in our traditional culture. The Goals of this study were as follows : 1) To identify patterns in caring behavior, 2) To identify the structural components of caring, and 3) To understand the meaning and some principles of caring. We faised several questions in this study. Who is the care-giver? Who is the care-receipient? Was the woman the major care -giver at any time? What are the patterns in caring behavior? What art the priciples underlying the caring process? We used an interdisciplinary team approach, composed of representatives from nursing and anthropology, to contribute in -depth understanding of caring through a socicaltural perspeetive. A Field study was conducted in Ro-Bong, a small agricultural kinship village. The subjects were nine women and one man aged be or more years of age. Data were collected from january 15 to 21, 1990 through opem-ended in-depth interviews and observations. The interview focused on caring behaviors sorrounding birth, aging, death and child rearing. We analysed these data for meaning, pattern and priciples of caring. In this report we describe caring behaviors surrounding childbirth. The care-givers were primarily mothers- in -low, other women in the family older than the mother - to- be, older neighbor woman, husbands, and mothers of the mother-to- be. The care receivers were the mother-to-be the baby, and the immediate family as a component of kinship. Emerging caring behavior included praying, helping proscribing, giving moral advice(Deug - Dam), showing concern, instructing, protecting, making preparations, showing consideration, touching, trusting, encouraging, giving emotional comfort, being with, worrying about, being patient, preventing problems, showing by an example, looking after bringing up, taking care of postnatal health, streng thening the health condition, entering into another's feelings(empathizing), and sharing food, joy and sorrow The emerging caring component were affection, touching, nurtuing, teaching, praying, comforting, encouraging, sharing. empathizing, self - discipline, protecting, preparing, helping and compassion. Emerging principles of. caring were solidarity, heir- archzeal relationships, sex - role distinction. Caring during birth expresses the valve of life and reflects the valued traditional beliefs that human birth is given by god and a unique unifying family event reaching back to include the ancestors and foreward to later generations. In addition, We found positive and rational foundations for traditionl caring behaviors surrounding birth, these should not be stigmatized as inational or superstitious. The nurse appropriately adopts the rational and positive nature of traditional caring behaviors to promote the quality of nursing care.

  • 지중강판 구조물은 강판부재 내에 발생하는 휨모멘트에는 매우 취약하기 때문에 그 주변을 양질의 흙으로 뒷채움하여 주변 흙과의 상호작용에 의하여 상부에 작용하는 하중을 지지한다. 그러나, 구조물 측면을 뒷채움할 때나 최소토피고를 확보하지 못한 상태에서 활하중이 작용할 때에는 강판부재내에 과도한 모멘트가 발생할 수 있다. 현재 설계기준에서는 허용변형량을 제시하여 시공 중에 과도한 변형이 발생하는 것을 방지하고 있으며 Duncan(1979)과 McGrath 등(2001)은 강도해석법을 제안하여 시공 중에 발생하는 모멘트를 강판의 소성강도 이내로 제한하고 있지만, 허용변형량은 경험적으로 규정한 값이고 강도해석에 의한 구조 안정성 검토는 유한요소 해석결과를 바탕으로 제안되었기 때문에 이들에 대하여 실험적 검증이 필요하다. 이 연구에서는 높은 아치형 구조물에 대한 실규모 현장시험을 실시하여 시공 중 거동과 활하중에 대한 하중지지 거동을 분석하였다. 시험결과를 바탕으로 시험시공 구조물의 허용변형량을 '높이의 1.45%' 로 추정할 수 있었는데 이는 설계기준의 허용값인 '높이의 2%' 보다 작은 값이었다. 또한, 계측결과를 Duncan과 McGrath 등이 제안한 강도해석결과와 비교하여 Duncan은 성토하중에 의한 모멘트는 과소평가하고 활하중 모멘트는 과대평가 하지만 McGrath 등은 두 값을 모두 실제와 근접하게 예측함을 알 수 있었다. 그러나, 두 방법에 의한 소성힌지에 대한 안전율은 실제 안전율과 잘 일치하여 두 방법 모두 시공 중에 작용하는 활하중에 대한 구조 안정성을 적절히 평가할 수 있음을 확인하였다.나 길항력(6.4 ㎜)은 남아있었다. 또한 분자량 10kDa 이하의 분획에서는 chitinase 활성은 없으나 길항력(5.2㎜)은 나타내었고, 80℃에서 열처리하여도 길항력(5.0mm)이 남아있어 효소 이외 다른 생리활성물질이 존재함을 확인하였다.rin, (+)-taxifolin 3-O--$\beta$-D-glucopyranoside, (+)-catechin 및 benzoic acid의 함량은 건조 및 처리 온도가 증가할 수록 감소하는 양상을 나타내었다.tier taste and the Doenjang with P. japonica Powder had the least sweet taste.

  • 이 연구의 목적은 우리나라 최초의 정부인가 교과서라 할 만한 현공렴 발행의 가정교과서의 외형적 내용적 측면과 함께 발행인 등 교과서가 발간되기까지의 배경을 분석하고 이들 가정교과서의 母本에 해당하는 일본의 가정교과서와 그 교과서의 저자에 대하여 살펴보는데 있다. 구체적인 연구결과를 살펴보면 다음과 같다. 1. 학부는 '교과용도서일람'을 발간함으로써 수업시간에 사용할 수 있는 교과서와 사용할 수 없는 교과서를 구별하였다. 가정교과서 역시 예외가 아니어서, 1910년 현재 학부인가 가정교과서는 현공렴 발행의 '한문가정학'과 '신편가정학'이지만, 1912년에 들어서면 이 교과서는 불인가교과서가 되며, 1914년에는 불인가 가정교과서 목록에 현공렴 발행의 '신정가정학'이 추가된다. 2. 정부인가 및 불인가 교과서를 발행한 현공렴은 조선전기부터 유명한 역관집안 출신이었다. 당시의 역관은 외국어에 능통하다는 이점으로 외국의 서적을 조선의 지식충에게 소개하는 가교적 역할을 하였다. 3. 현공렴이 발행한 '한문가정학', '신편가정학', '신정가정학'은 목차를 비교해 볼 때 거의 동일하다. 그런데 이 교과서는 1902년 7월 즈음에 중국에서 오여윤에 의해 발행되었고, 이 교과서를 현공렴이 1907변 12월 조선에서 한문본 '한문가정학',과 국한문본 '신편가정학'으로 발행하였다. 오여윤이 발행한 가정교과서의 모본은 1900년 시모다 우타코(하변가자)에 의해 발행된 '신선가정학', 상하권이다. 4. 현공렴 발행의 가정교과서는 '총론' '가인의 감독' '일가의 풍범', '위생', '일가의 재정' 등 5단원으로 구성되었으며, 이러한 내용은 그 모본에 해당하는 시모다의 '신선가정학' 교과내용과 상당한 차이를 보인다. 이 차이는 중국에서 발행된 오여윤에 의해 이루어졌다. 5. 가정 교과서에 나타난 가정은 (1)국가의 기본단위로서의 가정, (2)교육의 장으로서의 가정, (3)휴식의 장으로서의 가정, (4)소비의 장으로서의 가정으로 요약된다.

  • 본 연구에서는 사전개념 검사 문제를 분석하여 간단한 전기회로 개념에 관한 초등학생들의 오개념 유형을 알아보고, 인지갈등 검사문항으로 자신의 생각과 불일치한 동료 한명과 자유롭게 토론을 한 후의 인지갈등정도와 토론에서 사용한 같은 인지갈등 검사 문항으로 체험을 한 후의 인지갈등정도를 비교하였다. 대도시에 위치한 K초등학교 6학년 7개 학급 264명을 대상으로 학생들의 간단한 전기회로 개념에 관한 오개념 유형을 조사한 결과, 많은 학생들이 전구가 2개의 전기적 단자를 갖고 있음을 모르고 있었으며, 전구의 꼭지를 강조하거나 전지의 +극을 강조하는 경우가 있었고 단일극 모형을 가진 경우도 상당수 나타났다. 전지의 +극에 전구가 옆으로 뉘어져 있고 전선이 꼭지쇠와 전지 -극에 연결된 문항을 인지갈등 검사문항으로 선정하였다. 선정된 인지갈등 검사문항으로 미리 구성한 토론 조에게 동료의 생각을 듣고 학습지에 적도록 한 다음에 자유롭게 토론을 하게 하였으며, 토론을 마친 후에 인지갈등검사를 하였다. 토론 내용을 알아보기 위해서 몇 쌍은 녹음, 녹화하여 프로토콜을 전시하여 학생들의 생각을 알아보았다. 체험은 토론을 하지 않은 같은 학교 6학년 학생으로 짝과 함께 2인 1조로 직접 실험을 하여 인지갈등 정도를 측정하였다. 토론과 체험을 통한 인지갈등 요소별 응답 점수를 비교해 본 결과는 다음과 같다. 토론은 인지적 재평가, 불안, 인식, 흥미 순으로 인지갈등이 높게 나타났고 그 중에서 인지적 재평가가 높게 나타났다. 체험은 인식, 인지적 재평가, 흥미, 불안 순으로 인지갈등이 높게 나타났고 불안의 반응치가 현저하게 낮게 나타났다. 인지갈등 요소별 인지갈등 점수를 살펴보면 흥미, 불안, 인지적 재평가에서는 토론이 체험보다 점수가 높게 나타났다. 특히 불안 요소와 인지적 재평가 요소에서는 토론이 체험보다 점수가 높고 유의미한 차이를 보였다. 그 까닭은 직접 실험으로 확인하지 못하고 토론만 하였기 때문으로 생각된다. 토론집단의 남녀 차이에 따른 인지갈등 요소별 응답 점수를 분석한 결과 남자는 인지갈등 요소별 점수가 인지적 재평가, 인식, 불안, 흥미 순으로 높게 나타났다. 그 중에서 인식의 반응치가 높게 나타난 반면에 흥미 점수가 낮게 나타났다. 여자는 인지적 재평가, 불안, 흥미, 인식 순으로 높게 나타났고 인지적 재평가의 반응치가 그 중에서 높게 나타난 반면에 인식 점수가 낮게 나타났다. 토론으로 인지갈등을 유발했을 때 갈등 요소 중 인지적 재평가에서는 여자가 남자보다 점수가 높고 유의미한 차이를 보였고, 인식에서는 남자가 여자보다 점수가 높고 유의미한 차이를 보였다. 체험집단의 남녀 차이에 따른 인지갈등 요소별 응답 점수를 분석한 결과 체험으로 인지갈등을 일으켰을 때 인식요소를 제외한 흥미, 불안, 인지적 재평가 요소에서 남자가 여자보다 인지갈등 점수가 높게 나왔고, 특히 인지적 재평가 요소에서는 유의미한 차이를 보였다. 그 까닭은 남학생이 여학생보다 직접 실험하고 조작해 보는 경험을 많이 가졌기 때문이라고 생각된다.
