In this paper, we propose a privacy-preserving emergency call scheme, called PEC, enabling patients in life-threatening emergencies to fast and accurately transmit emergency data to the nearby helpers via mobile healthcare social networks (MHSNs). Once an emergency happens, the personal digital assistant (PDA) of the patient runs the PEC to collect the emergency data including emergency location, patient health record, as well as patient physiological condition. The PEC then generates an emergency call with the emergency data inside and epidemically disseminates it to every user in the patient's neighborhood. If a physician happens to be nearby, the PEC ensures the time used to notify the physician of the emergency is the shortest. We show via theoretical analysis that the PEC is able to provide fine-grained access control on the emergency data, where the access policy is set by patients themselves. Moreover, the PEC can withstandmultiple types of attacks, such as identity theft attack, forgery attack, and collusion attack. We also devise an effective revocation mechanism to make the revocable PEC (rPEC) resistant to inside attacks. In addition, we demonstrate via simulation that the PEC can significantly reduce the response time of emergency care in MHSNs.

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.

The implementation of IEEE 802.15.6 in Wireless Body Area Network (WBAN) is contention based. Meanwhile, IEEE 802.15.4 MAC provides limited 16 channels in the Superframe structure, making it unfit for N heterogeneous nature of patient's data. Also, the Beacon-enabled Carrier-Sense Multiple Access/Collision-Avoidance (CSMA/CA) scheduling access scheme in WBAN, allocates Contention-free Period (CAP) channels to emergency and non-emergency Biomedical Sensors (BMSs) using contention mechanism, increasing repetition in rounds. This reduces performance of the MAC protocol causing higher data collisions and delay, low data reliability, BMSs packet retransmissions and increased energy consumption. Moreover, it has no traffic differentiation method. This paper proposes a Low-delay Traffic-Aware Medium Access Control (LTA-MAC) protocol to provide sufficient channels with a higher bandwidth, and allocates them individually to non-emergency and emergency data. Also, a Contention Differentiated Adaptive Slot Allocation CSMA-CA (CDASA-CSMA/CA) for scheduling access scheme is proposed to reduce repetition in rounds, and assists in channels allocation to BMSs. Furthermore, an On-demand (OD) slot in the LTA-MAC to resolve the patient's data drops in the CSMA/CA scheme due to exceeding of threshold values in contentions is introduced. Simulation results demonstrate advantages of the proposed schemes over the IEEE 802.15.4 MAC and CSMA/CA scheme in terms of success rate, packet delivery delay, and energy consumption.

It has been reported that the cancer patient's quality of life is influenced by the perceived health state, self-esteem, health locus of control, social support, whether there is a pain or not, the stage of a disease, the period of a disease, etc, and however, there has been scarcely the research into the fact at home whose cultural and social backgrounds are entire1y different from those of American and European Countries. Accordingly, the author of this thesis performed this study. considering that it is necessary to know the relations between the health locus of control which make it possible to predict the object's behavior related to health and to make plans to induce the object or patient into sound behavior and the quality of life which is closely related to the cancer patient's health, emotion, society, economy, etc. on the whole. This study, a cross-sectional one, includes 135 subjects of $in{\cdot}out$ patients registered at Y University Hospital whose age are more than 20 years, From these patients, data were collected for two weeks through the questionnaire which content concerns about the quality of life and the health locus of control. All the collected data were processed and analyzed through Student's t-test, ANOVA, and the calculation of Pearson Correlation Coefficient, using the SAS program 1. It appeared that the disposition of health locus of control was mostly inclined to the disposition of powerful other health locus of control($28.37{\pm}4.24$), then inclined to internal health locus of control($27.03{\pm}4.17$), and next to chance health locus of control($19.71{\pm}4.97$) By the way. the disposition of powerful other health locus of control appeared a tittle bit higher than internal health locus of control 2. The degree of the quality of life appeared to be 137.54 points in the average of total points and 3.11 in the average evaluation mark. It appeared that the quality of life was most significantly influenced by a factor of 'relations with neighbors' and least significantly influenced by factors of physical conditions and functions. 3. It appeared that the relation between the disposition of health locus of control and the quality of life has nothing to do with the relation between internal health locus of control and the quality of life(r=.1446, P>.05) and also with the relation between the disposition of powerful other health locus of control(r=.0385, P>.05). In conclusion, in the study it has been found out that there is no correlation between the health locus of control and the quality of life, and however it is sound to induce the cancer patient to internal health locus of control. Therefore, it is necessary that under the special circumstances, the cancer patient's behavior should be predicted, thereby inducing the patient to the sound change of his or her behavior. Also in order that the patient enjoys his or her life satisfactorily while living, It is deemed that some kind of multilateral meditation in health and treatment is necessary so that the patient can feel the relief of pain, better health, etc.

Purpose: This study examined the influence of nurses' communication competency, critical thinking disposition, and perception of patient safety culture on patient safety competency in armed forces hospitals. Methods: A crosssectional design was employed with a convenience sample of 204 nurse officers from four armed forces hospitals in South Korea. Data were collected through a self-administered questionnaire from August 10~23, 2019, and analyzed using descriptive statistics, t-test, ANOVA, Pearson's correlation coefficients, and multiple regression. All analyses were conducted using SPSS for Windows 21.0. Results: Patient safety competency scores were 4.35±0.40 for patient safety attitudes, 3.63±0.64 for patient safety knowledge, and 3.94±0.51 for patient safety skill. Communication competency, critical thinking disposition, and perception of patient safety culture were positively correlated with patient safety competency. Communication competency (β=.30, p=.002) and perception of patient safety culture (β=.24, p=.001) were identified as particularly important factors influencing patient safety competency. Conclusion: This study's results suggest that education programs to enhance communication competency and patient safety culture could increase patient safety competency among nurses in armed forces hospitals.

This paper presents a user authentication scheme for healthcare application using wireless medical sensor networks, where wireless medical sensors are used for patients monitoring. These medical sensors' sense the patient body data and transmit it to the professionals (e.g., doctors, nurses, and surgeons). Since, the data of an individual are highly vulnerable; it must ensures that patients medical vital signs are secure, and are not exposed to an unauthorized person. In this regards, we have proposed a user1 authentication scheme for healthcare application using medical sensor networks. The proposed scheme includes: a novel two-factor professionals authentication (user authentication), where the healthcare professionals are authenticated before access the patient's body data; a secure session key is establish between the patient sensor node and the professional at the end of user authentication. Furthermore, the analysis shows that the proposed scheme is safeguard to various practical attacks and achieves efficiency at low computation cost.

Background: This study aimed to identify the impacts of job stress and cognitive failure on patient safety incidents among hospital nurses in Korea. Methods: The study included 279 nurses who worked for at least 6 months in five general hospitals in Korea. Data were collected with self-administered questionnaires designed to measure job stress, cognitive failure, and patient safety incidents. Results: This study showed that 27.9% of the participants had experienced patient safety incidents in the past 6 months. Factors affecting incidents were found to be shift work [odds ratio (OR) = 6.85], cognitive failure (OR = 2.92), lacking job autonomy (OR = 0.97), and job instability (OR = 1.02). Conclusion: Patient safety incidents were affected by shift work, cognitive failure, and job stress. Many countermeasures to reduce the incidents caused by shift work, and plans to reduce job stress to reduce the workers' cognitive failure are required. In addition, there is a necessity to reduce job instability and clearly define the scope and authority for duties that are directly related to the patient's safety.

The purpose of this study is to analyze the direct relationship between doctors and number of patients to be treated by applying many kinds of IE techniques. Generally, doctors in this research work both at Out Patient Data & In Patient Data. Under the hospital management system that they are applying in, doctor's daily working schedules are instable because the number of OPD patients daily. Therefore, the amount of time they spend for inward patients are variable too. So the numbers of patients have great influence to the whole hospital system management.

This study was designed to learn attitudes to euthanasia of nursing student. Data were collected from May 1 to May 30, 2005 by structured questionaires. The respondents joined in the study were 307 nursing student. Data were analyzed using SPSS program by percentage, t-test, one-way ANOVA and scheffe, The results obtained were as follows :1. The mean scores for euthanasia were 3.16 in medical ethics, 2.85 in respect for life, 2.83 in patient's rights, and 2.63 in quality of life, being 2.85 overall. 2. Those who have grade showed significantly higher scores for euthanasia. 3. About 56% of the respondents did not agree that passive euthanasia is justifiable, and 55% did not like performance of euthanasia. 4. The group admitting that passive euthanasia is ethically justifiable showed significantly higher scores in the patient's rights(t=6.031, p=.000), the respect for life(t=5.280, p=.000) and the medical ethics(t=5.558, p=.000) than the group which do not admit. 5. The group which would perform passive euthanasia showed significantly higher scores in the patient's rights(t=6.329, p=.000), the respect for life(t=6.339, p=.000), the quality of life (t=1.993, p=.047) and the medical ethics(t=6.240, p=.000) than the group which would not perform passive euthanasia.
