This study was conducted to identify the pain characteristics, family support and physical functioning and to determine predictors of the quality of life in aged women with chronic pain. Method: The questionnaires were collected through direct interview by a trained research assistant from July 2 to August 24, 2001. Subjects were 108 women clients with chronic pain over 65 years of age. Data analyzed frequency, percentage, mean, Pearson's correlation, ANOVA and stepwise multiple regression by SAS. Result: Care providers were mostly spouses and daughters in law. Care providers who took care of elderly for a few hours a day had the highest percentile. Aged women had persistently had chronic pain of moderate intensity and was moderately satisfied with pain management. The mean score of disability due to pain was 3 on a 10 point scale. The mean scores of physical function and quality of life were moderate and there were negative correlations between pain characteristics, physical functioning, and quality of life at the range from r=-.46 to r=-.83. Satisfaction with care, duration of pain, disability due to pain, and physical functioning accounted for 56% of the variance in perceived quality of life for aged women with chronic pain. Disability due to pain was the most predictable variable of quality of life and physical function was the second .Conclusion: The results suggest that care by family, education in pain control, prevention of disability, and maintenance of physical function are important to improve and maintain quality of life in aged women with chronic pain. Therefore, there is a need for program development that enhance family support and nursing intervention that focuses on active pain control.

Introduction: Maxillomandibular fixation (MMF) is essential before surgery under general anesthesia in maxillofacial trauma patients. MMF is used basically to reconstruct the occlusion and occlusal stability to recover the facial shape and oral functions. The arch bar and wire is a traditional method for MMF, but it can not only bring pressure to the periodontal ligaments and teeth but also cause a penetrating injury to the surgeons. Materials and Methods: In this study, 198 patients with an open reduction using a manual reduction without MMF from September 2005 to May 2010 in Dankook University Dental Hospital were subjected to a follow-up evaluation during the postoperative 4 months periods. This study evaluated the incidence of complications according to the condition of the patient (gender, age), the state of bony union of the fracture sites and a numeric rating scale evaluation for postoperative pain scoring. Results: 1. The complications were classified into major and minor according to the seriousness, and the major complication rate was as low as 2.02%. Only 2 cases of re-operations (1.01%) were encountered. In the classification according to the fracture line, plate fracture was observed in both cases of mandibular symphysis fracture, and angle fractures and loosening of two screws were noted in the case of mandibular angle fracture. 2. The complication rate was similar regardless of gender and age. 3. The degree of bony union was satisfactory, and the complication rate was reduced as the bony union improved. 4. More patients complained of pain as the operation time was increased. Conclusion: The use of MMF is not always necessary if a skilled assistant is provided to help manually reduce the fracture site. Compared to other studies of mandibular fracture surgery using MMF, the complication rate was similar using only manual reduction and the patients' discomfort was reduced without MMF.

This study was conducted to analyse the current clinical education of pediatric nursing in baccalaurate nursing program, then to give basic data for enhancing the quality of future clinical education of pediatric nursing. Data were collected through self-reported questionnaire by mail from December 2001 to February 2002. The subjects were 29 schools of 50 baccalaurate nursing education programs. The data were analysed by double raters, researcher and assistant researcher. The results were summarized as follows: 1. Twenty-eight schools had the objectives of the clinical education of pediatric nursing, and 28 schools in pediatric ward, 23 schools in nursery, 22 schools in neonatal intensive care unit(NICU), 15 schools in objectives related to profession by clinical site. 2. Credits on clinical education of pediatric nursing were most 15 schools of 3 credits. 3. The clinical sites were mainly the hospital that sick children were admitted in. 4. The clinical teacher were 9 types including pediatric professor and field nurse. 5. On teacher's role, the professor instructed the case study and conference, and field nurse instructed the patient assignment and nursing procedures. 6. All of schools used explanation and conference as a method of clinical education, 1 or 2 schools used PBL or role play or field study. 7. On clinical education content, most of school included Apgar scoring system, physical examination in newborn assessment, respira- tion maintenance, temperature maintenance, infection prevention, nutrition, and bath in newborn care. 8. On clinical education content, most of school included care of incubator, phototheraty, infusion, gavage feeding and how to use the instruments in NICU. Eighteen schools included attachment promotion, and 20 schools case study. 9. On clinical education content, most of school included a checklist of nursing procedures, case study, assessment of growth and development in pediatric ward and other sites. 10.There were various evaluation types in scores, measuring items. In conclusion, the results of this study revealed that there were some discrepancy in the objectives and contents, clinical sites on hospital focused, teacher's role, and diversity of measurement items and ratings in clinical education of pediatric nursing. There is a need for a standardization of content, clinical site, and evaluation tool to improve a quality of clinical education of pediatric nursing based on this study.

Ultrasound sonography(US) is used to evaluate various diseases of oral and maxillofacial region including salivary glands, soft tissue and jaw lesions because of easy accessibility and no hazard of ionizing radiation. Also, US can offer dynamic study showing real-time images during diagnostic or surgical procedure. US images provide accurate information about the internal features of lesions on the jaw prior to surgical treatment. Doppler images are used to visualize the vascular distribution of the lesions and to provide additional information to enhance diagnostic value. It is necessary to evaluate the diagnostic value of US and evaluate its usefulness by looking at clinical cases using US images. Therefore, US imaging may be recommended as an assistant image in evaluating jaw lesions. US images provided accurate information about the internal structure of lesions on the jaw prior to surgical treatment, and diagnostic value was enhanced by visualizing the vascular distribution of the lesion using doppler imaging. We report the protocol and suggest the effectiveness of US for various lesions and US-guided sialography.

Purpose: This research was conducted to explore the relationship between spiritual well being and life attitude among breast cancer patients who were operated, and to increase understanding for wholistic nursing care. Method: With spiritual well being from quality of life questionnaire in breast cancer survivors (QOL-BR 23) of Ferrell et al (1998) and Life attitude profile (LAP) of Recker & Peacock (1981), the data were collected by research assistant in a sample of 56 women with stage 1-stage 3 breast cancer at surgery OPD after follow-up care. Result: Mean spiritual wellbeing score of subject was 5.83 (0-10) and life attitude was 4.96 (1-7). There were significant differences in life attitude according to monthly income (F=3.22, p=.03), and in spiritual wellbeing according to monthly income (F=4.16, p=.01) and religion (t=-3.67, p=.001) among demographic characteristics. There was significant difference in spiritual wellbeing according to the period passed after operation (F=2.89, p=.04) among disease characteristics. From life attitude domain, the mean score of "will to meaning" was the highest (5.30) and "existential vacuum" was the lowest (4.58). There was a significant relationship between spiritual wellbeing and "will to meaning" subscale of life attitude (r=.521, p=.000). The correlation coefficient showed r= .513 between spiritual well being and life attitude. Conclusion: Nurses could promote positive life attitude for breast cancer patients by improving spiritual well being with the encouragement of having religion expecially for long term breast cancer survivors in the process of their rehabilitation.

세계체제론적 관점에서 본다면, 국제인구이동은 선택적 인구이동이라고 할 수 있으며, 이는 국가간 격차의 심화로 이어진다. 또한 문화적으로 보았을 때, 이는 목적지에서의 민족집단별 경쟁과 갈등. 혹은 조화와 같은복잡한 현상들을 유발한다. 기존의 동화론에 의하면, 민족성은 이주집단이 새로운 정착지에서 오랜기간 동안 생활하다보면 자연스럽게 그 성격이 악화되고. 이에 따라 민족집단의 공간적 격리 현상도 점차 사라지게 되는 것으로 간주된다. 그러나 현재 다민족으로 구성된 국가들에서의 다양한 사례를 보게 되면, 그러한 동화가 매우 더디게 진행되거나 혹은 정반대로 민족성과 민족집단장소가 오히려 강화되는 모습을 확인할 수 있다. 민족성과 민족집단장소의 재발견 혹은 재구성은 현대사회의 다문화주의 및 포스트모더니즘 이념과 밀접한 관련이 있다. 민족성과 민족집단장소는 다민족 국가나 도시에 있어서 문화와 경제를 풍요롭게 하는데 큰 역할을 할 수 있는 귀중한자산인 것이다.

Ubiquitous mobile computing is becoming easier and more attractive in this ambient technological Internet world. However, some portable devices such as Personal Digital Assistant (PDAs) and smart phones are still encountering inherent constraints of limited storages and computing resources. To alleviate this problem, we develop a cost-effective protocol, iATA to transfer ATA commands and data over TCP/IP network between mobile appliances and stationary servers. It provides mobile users a virtual storage platform which is physically resided at remote home or office. As communications are made through insecure Internet connections, security risks of adopting this service become a concern. There are many reported cases in the history where attackers masquerade as legitimate users, illegally access to network-based applications or systems by breaking through the poor authentication gates. In this paper, we propose a mutual authentication and secure session termination scheme as the first and last defense steps to combat identity thief and fraud threat in particular for iATA services. Random validation factors, large prime numbers, current timestamps, one-way hash functions and one-time session key are deployed accordingly in the scheme. Moreover, we employ the concept of hard factorization problem (HFP) in the termination phase to against fraud termination requests. Theoretical security analysis discussed in later section indicates the scheme supports mutual authentication and is robust against several attacks such as verifiers' impersonation, replay attack, denial-of-services (DoS) attack and so on.
