The purpose of this study was to develop a computer-assisted patients menu planning program for hospital dietetics in order to improve the quality of menu for patients and to release managers from repetitive and routine tasks. Using this program, dietitians can spend more time on professional tasks. Moreover, few studies have been done on computer assisted patients menu planning for patients who need special diets for treatment in domestic hospital dietetics, therefore this program could be a great contribution. A 16-bit personal computer compatible with IBM-PC/AT was used. The data base files and processing program were created by Clipper package ver 5.0. This system can collect a number of meals, plan patients menu and computerize nutrient analysis. The future study will develop program(s) for purchasing, inventory control and data correction. The contents of computerized system are summarized as follows. 1. The number of daily meals of special and general diets given to the patients are collected and saved in database. These data were for the monthly list of meal census which could be printed out on the screen and/or the printer. 2. The menu planning was largely consisted of 2 sections. One was for the patients who require special diets and the other was general diet. And the special diets was divided into 6 sub-sections: diabetic, low-salt, low-fat, low-salt/low-protein, low-fat/low-cholesterol and low residue diets. 3. The nutrient analysis was composed of 11 diet. Sections and diebetic diet was divided into 9 sub-sections according to the calorie requirement. The calculated results were compared with the standards which were established by the hospital dietetic department.

Medical data is one of the data that must be kept in safe containers, far from intrusion, viewing and modification. With the technological developments in hospital systems and the use of cloud computing, it has become necessary to save, encrypt and even hide data from the eyes of attackers. Medical data includes medical images, whether they are x-ray images of patients or others, or even documents that have been saved in the image format. In this review, we review the latest research and the latest tools and algorithms that are used to protect, encrypt and hide these images, and discuss the most important challenges facing these areas.

Purpose: The purpose of this study was to evaluate hospital service utilization by the types of hospitals in Type I Medicaid claims frequently cited by elderly beneficiaries. Methods: Three frequently claimed inpatient diseases were selected: cerebral infarction, hypertension and diabetes mellitus. Relevant data were collected for the year 2008 from the computer database of the National Health Insurance Corporation. The data was analyzed using SPSS by descriptive statistics, ANOVA and coefficient of variation. Results: The coefficient of variance of hospitalization per episode was higher than daily hospital expenditure among hospitals for all three diseases. The coefficient of variance of hospitalization per episode was highest for cerebral infarction. The coefficient of variation of hospital expenditure per hospital day was highest for hypertension. Conclusions: Evaluating of the volume and pattern of hospital service utilization and the appropriateness for hospital admission for Type-I Medicaid elderly beneficiaries is important for Medicaid-based case management.

Background: Most pain management techniques for challenging procedures are still performed under the guidance of the C-arm fluoroscope although it is sometimes difficult for even experienced clinicians to understand the modified three-dimensional anatomy as a two-dimensional X-ray image. To overcome these difficulties, the development of a virtual simulator may be helpful. Therefore, in this study, the authors developed a virtual simulator and presented its clinical application cases. Methods: We developed a computer program to simulate the actual environment of the procedure. Computed tomography (CT) Digital Imaging and Communications in Medicine (DICOM) data were used for the simulations. Virtual needle placement was simulated at the most appropriate position for a successful block. Using a virtual C-arm, the authors searched for the position of the C-arm at which the needle was visualized as a point. The positional relationships between the anatomy of the patient and the needle were identified. Results: For the simulations, the CT DICOM data of patients who visited the outpatient clinic was used. When the patients revisited the clinic, images similar to the simulated images were obtained by manipulating the C-arm. Transforaminal epidural injection, which was difficult to perform due to severe spinal deformity, and the challenging procedures of the superior hypogastric plexus block and Gasserian ganglion block, were successfully performed with the help of the simulation. Conclusions: We created a pre-procedural virtual simulation and demonstrated its successful application in patients who are expected to undergo challenging procedures.

A Clinical Pathway(CP) is standard process to way of treat diseases or injuries which is adapted to each hospital based on National Clinical Practice Guideline(CPG). Since CP is standard guideline for doctors and nurses working in a hospital, making and modifying CP is one of the most important administrational work for hospital and also rare work because once it is fixed, it's not changed whether there are new kind of disease discovered or new treatment is developed. However, in present, patient's waiting time during hospital residence process, is discussed as service competitive for patients. In this research, we utilize process mining tool to verify patients treatment process follows CP with EMR(Electronic Medical Record) in a sample hospital, and suggest modifcation point of CP through verification.

The purpose of this study was to investigate how internal marketing affects self-efficacy and hospital image in university hospital nurses. In addition, it was to identify which factors of internal marketing is the most important factor perceived by the nurses. The sample consisted of 228 nurses working in one university hospital located in Changwon city of Gyeongnam province. The measurements included internal communication (5 items), empowerment (5 items), reward (3 items), education and training (5 items), working environment (3 items), leadership (5 items), self-efficacy (5 items), and hospital image (8 items) based on a review of related previous studies. Survey data were analyzed employing SPSS version 20.0 and AMOS version 20.0. The nurses rated internal communication (0.887) of the internal marketing sub-factors the most important, while they evaluated working environment (0.802) the lowest. The internal marketing perceived by nurses has a positive effect on self-efficacy (0.476) and hospital image (0.674). Nurses' self-efficacy also had a positive effect on hospital image (0.226). The findings reveal that the managers should build a positive climate of internal marketing activities in order to enhance nurses' self-efficacy and hospital image.

USN(Ubiquitous Sensor Network)는 환자의 생체 정보를 실시간으로 수집하고 수집된 정보를 DB(Data Base)에 저장을 한다. DB에 저장된 환자의 생체 정보는 환자가 자주 이용하는 병원에 저장되어 환자가 병원을 이용 할 경우 저장되어 있는 환자의 생체 정보를 가지고 진료를 하게 된다. 하지만 저장되어 있는 위치는 병원 내의 서버나 PC 환경에 저장을 해놓고 있기 때문에 환자가 다른 병원을 이용하게 될 경우 기존 병원의 DB에 요청을 해야 한다. 하지만 기존 병원은 보안, 인증, 관리, 비용, 인력 등의 문제가 있기 때문에 다른 병원과의 정보 교환이 쉽게 이루어지지 않는 문제가 있다. 그래서 환자의 생체 정보가 환자의 모바일 기기에 저장 되어 있는 경우 그대로 사용할 수 있다는 장점이 있다. DB는 정보를 빠르고 정확하게 찾는 것이 중요하다. 본 연구에서는 환자 중심의 서비스를 위한 모바일 순환 Loop DB 시스템을 연구한다.

Background: The present study introduces the design and fabrication of a simple surgical guide with which to perform genioplasty. Methods: A three-dimensional reconstruction of the patient's cranio-maxilla region was built, with a dentofacial skeletal model, then derived from CT DICOM data. A surgical simulation was performed on the maxilla and mandible, using three-dimensional cephalometry. We then simulated a full genioplasty, in silico, using the three-dimensional (3D) model of the mandible, according to the final surgical treatment plan. The simulation allowed us to design a surgical guide for genioplasty, which was then computer-rendered and 3D-printed. The manufactured surgical device was ultimately used in an actual genioplasty to guide the osteotomy and to move the cut bone segment to the intended location. Results: We successfully performed the osteotomy, as planned during a genioplasty, using the computer-aided design and computer-aided manufacturing (CAD/CAM) surgical guide that we initially designed and tested using simulated surgery. Conclusions: The surgical guide that we developed proved to be a simple and practical tool with which to assist the surgeon in accurately cutting and removing bone segments, during a genioplasty surgery, as preoperatively planned during 3D surgical simulations.

The purpose of this study was to examine the meaning and structure of nurses' computer using experience. To do this, we conducted a total of three interviews with 11 nurses working between the ages of 26 and 48. Interview data were interpreted using Giori method (1985) and Lincoln & Guba method (1985). As a result, 112 semantic units were derived, and then 18 sub-components were divided into 5 final components. As a result of the analysis, the computer experience that the nurses used in the hospital consisted of 'used for almost every task', 'usefulness', 'important', 'convenience', 'burden', 'anxiety', desire', simple work level', 'no problems', 'eye, muscle and movement discomfort', 'depends on task', 'more complex', 'accuracy', 'organize contents', 'simple', 'incomparable', and 'easy'. Based on the above conclusions, the nurses' experiences of using the computer in the hospital could be concluded as follows. Currently, almost all nursing jobs in hospitals are using computers. However, most of the tasks related to simple computer tasks related to the ability to use the computer was low, and because of this, the computer did not work properly, or when new programs were introduced to feel the burden and anxiety, want more systematic computer education Found. Especially, according to the career, the difference between computer and hand work was different, Nurses over 20 years said that computers can handle simple tasks that are a bit more complicated than manual tasks, whereas emotional tasks were handicapped, in the 10 to 20 years of experience, computer work was more accurate and appropriate to organize content, Nurses under 10 years were not only easy to work with computers but also have no experience in manual work, they could not compare the computer and the hand work. This study suggests that the use of computers in nurses' work is essential and that more systematic computer-based education should be provided. In addition, due to the nature of the nursing service, the professional opinions of the nurses should be reflected in the development of programs for the emotional nursing work.
