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.

Purpose : This study aims at analyzing perception of death anxiety among juniors and seniors majoring in emergency medical technology to provide data which can contribute to curricular design associated with death that meets characteristics of the students majoring in emergency medical technology as pre-service emergency medical technicians. Methods : This study was conducted with 210 students as juniors or seniors majoring in emergency medical technology at four colleges in some regions(Yeongnam district), finally using 177 copies for data processing. Data collection was carried out from April 11 through May 16, 2008, Analysis was performed using frequency analysis, t-test, and ANOVA. Statistical processing was implemented using an SPSS WIN 15.0 program. Results: 1. 83.6% of students majoring in emergency medical technology had no experience in getting learning about death. 58.7% were afraid of death 'because they would be sad to be separated from things they loved,' 2. The general degree of death anxiety measured in the four-point scale was 2.54(.33). 3. As for differences in death anxiety among students majoring in emergency medical technology by grades, seniors(2.64) showed a lower score for anxiety than juniors(2.74) in terms of 'anxiety about others' death.' 4. As for differences in death anxiety among students majoring in emergency medical technology by gender, female students(2.64) showed a higher degree of death anxiety than males students(2.44), Conclusion : It is necessary to develop education and programs associated with death anxiety in order to reduce fear and anxiety about death and accept one's own death in a positive way through patients in imminent death.

Objectives To obtain future research basis of Korean Medicine for total knee arthroplasty patient by analyzing medical and Korean Medical service utilization and treatment duration. Methods Data sampling was performed on Health Insurance Review and Assessment Service patient data of 2015 (Confidence level of 97%) to analyze patients' medical and Korean Medical service tendency. Sampling groups were divided into two groups; i) Patients who completed their treatment within 5 months of total knee arthroplasty, ii) Patients who continued their treatment after 5 months of total knee arthroplasty, to investigate patients' medical and Korean Medical service tendency and individual characteristics were carefully monitored. Results It was confirmed that total of 1,655 patients had gone through total knee arthroplasty out of 1,453,486 patients who were gathered for sampling. First sampling group (Patients who completed their treatment within 5 months of total knee arthroplasty) was 287 patients and second sampling group (Patients who continued their treatment after 5 months of total knee arthroplasty) was 385 patients. The proportion of patients who visited Korean Medical service in first sampling group was lower than that of second sampling group. Conclusions It was confirmed that medical and Korean Medical service and cost consumed by second group (Patients who continued their treatment after 5 months of total knee arthroplasty) was higher than that of first group (Patients who continued their treatment after 5 months of total knee arthroplasty). It is highly recommended to continue with further study for efficient medical and Korean Medical service and reduced cost.

In this paper, a medical image processing system was designed and implemented for morphometric and functional analysis of a human brain. The system is composed of image registration, ROI(region of interest) analysis, functional analysis, image visualization, 3D medical image database management system(DBMS), and database. The software processes an anatomical and functional image as input data, and provides visual and quantitative results. Input data and intermediate or final output data are stored to the database as several data types by the DBMS for other further image processing. In the experiment, the ROI analysis, for a normal, a tumor, a Parkinson's decease, and a depression case, showed that the system is useful for morphometric and functional analysis of a human brain.

So far, DW(data warehouse) of hospital has been used as tool for analyzing patient-focused data. However, EMR(Electronic Medical Record) is established these days, so informal data which is record and video record could be useful to get some information for patient remedy, not as DW data. This study claims that need of establishing treatment-focused DW, not for hospital administration-focused DW which has been used lots of hospital DW. Also we discussed how CDW can be applied for real medication situation. At last, we deduct a relation past record of sick and wounded patient as Thesaurus searching method by real hospital data for establishing base of early-treatment system.

Due to the increasing need for data sharing in the age of big data, how to achieve data access control and implement user permission revocation in the blockchain environment becomes an urgent problem. To solve the above problems, we propose a novel blockchain-based data sharing scheme (BDSS) with fine-grained access control and permission revocation in this paper, which regards the medical environment as the application scenario. In this scheme, we separate the public part and private part of the electronic medical record (EMR). Then, we use symmetric searchable encryption (SSE) technology to encrypt these two parts separately, and use attribute-based encryption (ABE) technology to encrypt symmetric keys which used in SSE technology separately. This guarantees better fine-grained access control and makes patients to share data at ease. In addition, we design a mechanism for EMR permission grant and revocation so that hospital can verify attribute set to determine whether to grant and revoke access permission through blockchain, so it is no longer necessary for ciphertext re-encryption and key update. Finally, security analysis, security proof and performance evaluation demonstrate that the proposed scheme is safe and effective in practical applications.

Purpose: This study was done to help provide patients with information on medical insurance cost through medical insurance education for nurses, to increase effective management, check on omissions in treatment and appropriateness and accuracy of fees, and to contribute to the economic growth of hospital by providing nurses with necessary knowledge about medical insurance cost. Method: The participants in this study were clinical nurses in general hospitals. The study instrument was a questionnaire developed by the researcher through reference to data for medical insurance education. The data were analyzed with percentages, means, ANOVA, and Duncan method using SPSS PC+10. Result: The results on knowledge of medical insurance according to general characteristics of the nurses showed that there were significant differences according to age: (p=.0036) highest level of education (p=.0007), position (p=.0010) and place where education on medical insurance was received (p=.0093). Conclusion: Continuous in-service education for clinical nurses is reflected in increased knowledge about medical insurance costs but special attention needs to be given to younger nurses and nurses with less education, as well as staff nurses, and those nurses who only received education on medical insurance during their schooling. Accordingly, in-service education is necessary for nurses at the time of orientation so that they have knowledge on standards for recuperation allowance, guidelines to calculate material costs, and guidelines to calculate drug rates. In addition, as medical insurance cost frequently change, all nurses need continuous in-service education.

Purpose: To provide legislative data for the amendment of Article 36 of the Emergency Medical Service Act on the qualifications of emergency medical technicians. Methods: The study was drafted based on the Emergency Medical Service Act; data on the emergency medical technicians (EMT) system and curriculum in Korea, United States. Japan, and Taiwan; and previous studies on the EMT system in Korea. Results: The length of education. work scope. amd role of level 1 EMTs vary significantly depending on the type of qualifications they have as emergency medical professionals, while the supply of level 1 EMTs has already reached a point of saturation. Accordingly, the current regulation on allowing level 2 EMTs with at least three years of experience to take the level 1 EMT test presents serious inequity for students just graduating from their emergency medical services program. It is also a factor that degrades the professionalism of level 1 EMTs. Conclusion: Article 36, paragraph 2. subparagraph 3 of the Emergency Medical Services Act pertaining to regulations on "EMTs who have worked as level 2 EMTs for at least 3 years" needs to be removed.

This study was conducted to evaluate the accuracy of the official death registry in rural area. The base data used for the study was 379 deaths registered during the period of 1993 and 1994 in 4 rural townships of Chonnam province. The interview survey for cause-of-death was performed on the next of kin and/or neighbor. Additional medical informations were collected from hospitals and medical insurance associations for the purpose of verification. The underlying cause-of-death of 278 cases presumed by the survey was compared to the cause on official death registry. There was a prominent disagreement of cause-of-death between the survey data and the registry data(agreement rate: $38.9\sim44.6%$, according to disease classification method). These results may be caused by extremely low rates of physicians' certification, which were mostly confined to the poisoning and injury. Symptoms, signs, and ill defined conditions on death registry could be classified into circulatory disease(32.3%), neoplasm(21.2%), digestive disease(7.1%), injury and poisoning(7.1%) and so on. These results suggest that careful attention and verification be required on utilization of death registry data in rural area.
