Purpose: This study was conducted to analyze and clarify the meaning of the concept for relocation stress -focusing on patients transferred from an intensive care unit to a general ward. Methods: This study used Walker and Avant's process of concept analysis. Results: Relocation stress can be defined by these attributes as follows: 1) involuntary decision about relocation, 2) moving from a familiar and safe environment to an unfamiliar one, 3) broken relationship of safety and familiarity, 4) physiological and psychosocial change after relocation. The antecedents of relocation stress consisted of these facts: 1) preparation degrees of transfer from the intensive care unit to a general ward, 2) pertinence of the information related to the transfer process, 3) change of major caregivers, 4) change in numbers of monitoring devices, 5) change in the level of self-care. There are consequences occurring as a result of relocation stress: 1) decrease in patients' quality of life, 2) decrease in coping capacity, 3) loss of control. Conclusion: Relocation stress is a core concept in intensive nursing care. Using this concept will contribute to continuity of intensive nursing care.

Based on the theory of local-world network, the composition self-similarity (CSS) of network traffic is presented for the first time in this paper for the study of DoS detection. We propose the concept of composition distribution graph and design the relative operations. The $(R/S)^d$ algorithm is designed for calculating the Hurst parameter. Based on composition distribution graph and Kullback Leibler (KL) divergence, we propose the composition self-similarity anomaly detection (CSSD) method for the detection of DoS attacks. We evaluate the effectiveness of the proposed method. Compared to other entropy based anomaly detection methods, our method is more accurate and with higher sensitivity in the detection of DoS attacks.

Nursing's traditional concern for human well being includes concern for health promotion. Until recently textbooks of preventive medicine, public health and community health nursing have defined health prevention- the prevention of disease and health protection or maintenace, but not health promotion. Lack of clear definitions inhibit effective communication among health related disciplines. Therefore, this studys task was the analysis and definition of the concept of health promotion using Walker & Avant's concept analysis methodology. This characteristics of the concept of health promotion are 1) orientation toward well - being, 2) empowering, 3) subjectivity, 4) change and 5) expanded connecteness. Antecedent of health promotion are 1) attaining of a healthy state, 2) having purpose and will to act, 3) persistent and realistic behaviour. The consequences of health promotion are 1) prolonged life, 2) self-actualizing potential, 3) increased well-being and a high level quality of life. The future direction of health promotion research should include that identification of the differences in the definition of between health professionals and health clients and research related to nursing theory of health promotion.

This study was conducted to develop the hydraulic brake assembly for MUAV(Medium-altitude Unmanned Aerial Vehicle). The brake assembly has the self-gap adjuster which performs to maintain a constant gap between the piston and the disk, even if the friction pad wore down. The function of adjuster helps to keep the brake-reaction speed constant and prevent the unnecessary abrasion of the wear pad during the life of the brake assembly. The development of the aircraft hydraulic brake assembly with the self-gap-adjuster in this paper is the first ever in South Korea. The concept of the mechanism was defined and the formula which is necessary to calculate the friction force was set up in the paper. The tester was invented for the functional test and the proper operation of the self-gap-adjuster was confirmed through the test. Dynamo tests and flight tests were also carried out to verify the braking performance of the brake assembly.

In the setting of extended quasi b-metric spaces, we introduce a new concept called "extended A-contraction". We then use our concept to prove a common fixed point result for a pair of self mappings under a set of conditions. Also, we provide the concepts of extended B-contraction and extended R-contraction. We then establish a common fixed point under these new contractions. Our results generalize many existing result of fixed point in metric spaces. Furthermore, we give an example to illustrate and support our result.

Purpose: This study aimed to provide a theoretical basis for career anchors of nurses by defining and organizing its concept. Methods: Using the Walker and Avant concept analysis, a total of 29 articles were analyzed through a literature search in this study. Results: The career anchors of nurses are individual career choice motives, a self-concept where in competency and values are harmonized, which act as a desire for growth and development in nursing, and are actions that maintain careers. Additionally, they indicate the direction for achieving individual career goals and act as a core value expected of nurses by nursing organizations, indicating continuous and integrated professional growth and development of the nursing profession. Conclusion: The career anchors of nurses identified in the results contribute to securing patient safety, providing quality care through policies, institutionalizing bases for career development, preventing nurse turnover, and retaining skilled nurses.

The purpose of this study is to act nursing intervention strategies to promote quality of life (QOL) in Spinal Cord Injury patients. Therefore, the study is designed to evaluate religion, marital status, educational background economic status, level of injury, voiding pattern, transportation by driving, rehabilitation education, self-concept, sexual status, perceived barrier, powerlessness, depression, hope, social support, self-efficacy, anxiety, ADL, perceived hopelessness, personality and pain for QOL at the same time. It was gathered empirical data was collected using a self report questionnaire from 61 patients during a six month period after SCI at 5 general hospitals, at 2 rehabilitation centers and at 2 rehabilitation schools province from Jun. 18, 1999 through Sep. 28, 1999. The reliability of the 19 instruments was tested with Cronbach's alpha which ranged from .6319 to .9769. For the data analysis a SAS program was used for Pearson correlation coefficients, and stepwise multiple regression. The results were as follows; 1. The mean of total item score in the QOL scale was 2.814, which showed a much lower score than the cancer points. 2. There was a significant correlation between self concept, transportation by driving, perceived barrier, powerlessness, depression, hope, social support, self-efficacy, anxiety, ADL and QOL.(${\gamma}$= .27~-.79, p< .05) 3. Stepwise multiple regression analysis showed that; a) Depression was the main predictor of QOL and account for 53.7% of the variance in QOL. b) Hope, ecomic status and body satisfaction accounted for 8%, 4%, 3.4% respectively and these variables combined accounted for 69.2% of the variance in QOL. In conclusion, to begin with, it is important to reduce depression and to help for SCI points to inspire hope, economic status and body satisfaction. That will be short cut for nursing strategies to enhance QOL.

Objectives: The purpose of this study was to understand health-promotion behaviors and to find factors associated with the behaviors among Korean-Chinese workers who live in Korea. Methods: The number of Korean-Chinese workers participated in this study was 187, and the sample was chosen using a convenient sampling method. To understand general characteristics, frequencies and percentages were utilized. To examine the seven categories of health-promotion behavior, their average scores were calculated. To explore factors related to health-promotion behaviors, a multiple stepwise regression analysis was performed. Independent variables used for the analysis were self-concept, social support, stress, perceived health status, and demographics. Results: The average score of the seven health-promotion behaviors was 2.35. Of the seven subcategories of health-promotion behaviors, the scores of rest/sleep and self-actualization were relatively higher; the scores of exercise and stress management were relatively lower. Of demographics and four factors of main interest (i.e., self-concept, social support, stress, perceived health status), education level, types of residence, social support, and perceived health status remained statistically significant. Among the four factors, social support had the greatest impact on health-promotion behaviors. Conclusions: This study has two suggestions. First, it is needed to develop strategies, which can help Korean-Chinese workers enhance levels of health-promotion behaviors regarding stress management and exercise. Second, considering the greatest effect of social support on health-promotion behavior, it is necessary to strengthen social support among Korean-Chinese workers.
