This research has been conducted in order to compare and analyze the role-conflict, job stress and job satisfaction of nurses according to their current work posts. The subjects of this research were carefully selected 426 nurses from 2 university hospitals. The research tool were a role-conflict measurement index, job stress a tool, and job satisfaction Minnesota Satisfaction Questionnaire. The data have been collected using a structured questionnaire from March to May 2003. The collected data have been analyzed using the SPSS PC 10.0V program. The nurses at Intensive Care Unit (ICU) showed highest level of job stress while the nurses at surgical ward showed the lowest level of job stress (F=8.37, p=.000). There was no significant difference in role-conflict and job satisfaction according to the current work posts. According to the results of this research, there was a difference in stress according to the current work posts, and it turned out that the nurses at ICU had the highest level of stress compared to the nurses at other departments, and it causes a fall in job satisfaction.

Purpose: The purpose of this descriptive study was to determine the perception of physicians and nurses on family presence during invasive procedures. Methods: The study population consisted of 100 physicians and 100 nurses from five hospitals which have more than 500 beds in B city. Data collection was done from August 20 to September 19, 2007. The Family Presence During Resuscitation (FPDR) Inventory developed by Fulbrook, Albarran and Latour (2005) was used as the study instrument. The collected data was analyzed by t-test, ANOVA and Duncan's multiple range test using SPSS/WIN 14.0 version. Results: Nurses had more positive attitudes to allowing family members to be present during invasive procedures than physicians did. However, compared to physicians, nurses had more concern about problems of confidentiality, arguing with medical team, and increased rate of legal action if family members were present during invasive procedure. Conclusion: The results of this study indicate that educational programs and policy for family presence be required within the hospital to enhance the perception of physicians and nurses to the family presence.

Purpose: A quasi-experimental study was performed to investigate the effects of a home visiting discharge education program on the maternal self-esteem, attachment, postpartum depression and family function in 35 mothers of neonatal intensive care unit (NICU) infants. Methods: Twenty-three mothers in the intervention group received the home visiting discharge education while 12 mothers in the control group received the routine, hospital discharge education. Baseline data was collected in both groups one day after delivery. The intervention group received the home visiting discharge education while the control group did the routine hospital-based discharge education. The questionnaire including the data on maternal self-esteem, attachment, postpartum depression and family function were collected within 1 week after the discharge by mail. Results: The scores of maternal self-esteem, and attachment were significantly increased, and the postpartum depression and the family function score were decreased after the home visiting discharge education in intervention group. There were no changes in these variables before and after the routine hospital-based discharge education in control group. Conclusion: These results support the beneficial effects of home visiting discharge education on the maternal role adaptation and family function of the mothers of NICU infants.

Purpose: This study was to determine ICU nurses noncompliance of critical care nursing standards in order to provide basic data for education aimed at improvement in practice and evaluation of quality of nursing care in ICU. Methods: Data was collected from 150 nurses who work for three educational hospitals which have more than 800 beds and located in Gyeonggi province using questionnaires from September 2007 to October 2007. Results: The highest categories of noncompliance of critical care nursing standards were admission care($2.71\pm.60$) and infection control($2.31\pm.70$). The main causes of noncompliance critical care nursing standards that nurses regarded as causes were lack of attention(80.7%). ICU nurses mainly reported their noncompliance to charge nurses(89.3%) within 30minutes (84.7%). The reasons they reported were to solve problems rapidly and correctly, to reduce a harm to patients, and to prevent making noncompliance again. The reasons they didn't report were that they thought it might be not a problem and there was no change of patients conditions. Conclusion: ICU nurses noncompliance of critical care nursing standards was determined, therefore it can be used for prevention of further noncompliance.

Purpose: This study was a descriptive correlation research to identify the relationships between nursing performance, compassion fatigue, and job stress in emergency room nurses and to provide basic data on reducing job stress in emergency room nurses. Methods: For the research, this study collected data from August 4 to September 26 with 133 nurses who worked at emergency rooms at 3 general hospitals in Gyeonggi-do with 500 beds, and analyzed using descriptive statistics, t-test, ANOVA, Pearson correlation coefficient with the SPSS 21.0 program. Results: Correlation analysis between nursing performance, compassion fatigue, and job stress demonstrated that the job stress had a significant positive correlation with compassion fatigue and nursing performance. On the other hand, there was no statistically significant correlation between compassion fatigue and nursing performance. Conclusion: The study results showed that the emergency room nurse experienced job stress due to intensive compassion fatigue and nursing performance. Thus, it is necessary to develop intervention programs to reduce job stress in emergency room nurses by alleviating compassion stress and having moderate level of nursing performance.

Purpose: The purpose of this study was to assess the educational needs of ICU nurses based on an analysis of importance, frequency, and difficulty for ICU nursing practice. Method: A cross-sectional survey was conducted using a questionnaire with 80 questions in 14 ICU nursing categories. Data were collected from August to October 2009. A total of 295 ICU nurses from five hospitals who had minimum of one year clinical experience participated. Data were analyzed with using descriptive statistics. Results: For importance, emergency care had the highest score, followed by physical assessment, communication, cardiovascular care, and ICU basic nursing. Regarding the frequency, physical assessment had the highest score, followed by communication, medication, ICU basic nursing, and respiratory care. Cardiovascular care was the most difficult task, followed by neurological care, emergency care, other ICU related nursing care, diagnostic test, and communication. Conclusion: The findings indicate a high educational need in the areas of communication, medication, physical assessment, diagnostic test, emergency care, and cardiovascular care. Thus the development of educational programs on communication, medication, physical assessment, diagnostic test, emergency care, and cardiovascular care are needed for ICU nurses.

SPT-CL J2106-5844 is the most massive galaxy cluster at z>1 discovered to date. It has been known to be an isolated system with a singular, well-defined halo. However, recent studies provide lines of evidence for its merging state. We strengthen the case with the multi-wavelength observations from ALMA, ACA, ASKAP, ATCA, and Chandra. With the sensitive, high resolution ALMA+ACA observations, we reconstruct the ICM pressure map from the thermal SZ effect. It reveals two main gas components that are associated with the mass clumps inferred from the weak-lensing analysis. Furthermore, the X-ray hardness map supports the bimodal gas distribution. With these multi-wavelength data, we probe the merger phase in SPT-CL J2106-5844.

Pain is a subjective and multidemensional concept. Therefore the patient's expression of pain have been referedl to the best believable indicator of pain condition but the support data obtained from the patient considered cultural difference is a deficient condition in determinded on the precise nursing diagnosis. The purpose of this reasearch was to understand multiple pain reponses in cultural difference and sensitivity, to encourage communication between medical teams, and to provide the foundation data of on data of precise nursing assessment for the patient in pain. The research problem was to grasp pain express pattern of Korean peptic ulcer patients. The subjects were 20 peptic ulcer patients in medical unit or OPD of twp university hospitals in Seoul. Data were collected from September 7th to 22nd, 1990 by intensive interviews. Interviews were done by the researcher and all were tape - recorded. The Data analysis was done by Phenomenological method from Van Kaam. Validity assured by confirmation of the internal consistency of the statements and catigory by nursing collegue in educational and clinicions in medical care. From the emic data, 96 descriptive statements were organized in 18 theme cluster. The results of study were summerized as follows. 1. Pain Express Pattern cluster of Peptic Ulcer Patients were “Pain as clogging”, “shallow pain”, “pain as pressing”, “nauseating pain”, “pain as smarting”, “pain as pulling”, “pain as pricking”, “pain as bursting”, “wrenching pain”, “excising pain”, “uncontrollable pain for mind and body”, “awakening pain”, “pain as hollowing” and the other cluster. As above mentioned, Pain Express Pattern of Peptic Ulcer Patient appeared diversely in verbal and they were propered to Korean culture. Therefore they will provide for the foundation data of precise nursing assessment.

Mobile social network is becoming more and more popular with respect to the development and popularity of mobile devices and interpersonal sociality. As the amount of social data increases in a great deal and cloud computing techniques become developed, the architecture of mobile social network is evolved into cloud-based that mobile clients send data to the cloud and make data accessible from clients. The data in the cloud should be stored in a secure fashion to protect user privacy and restrict data sharing defined by users. Ciphertext-policy attribute-based encryption (CP-ABE) is currently considered to be a promising security solution for cloud-based mobile social network to encrypt the sensitive data. However, its ciphertext size and decryption time grow linearly with the attribute numbers in the access structure. In order to reduce the computing overhead held by the mobile devices, in this paper we propose a new Outsourcing decryption and Match-then-decrypt CP-ABE algorithm (OM-CP-ABE) which firstly outsources the computation-intensive bilinear pairing operations to a proxy, and secondly performs the decryption test on the attributes set matching access policy in ciphertexts. The experimental performance assessments show the security strength and efficiency of the proposed solution in terms of computation, communication, and storage. Also, our construction is proven to be replayable choosen-ciphertext attacks (RCCA) secure based on the decisional bilinear Diffie-Hellman (DBDH) assumption in the standard model.
