It is needed to support intelligent customized health information service for user convenience in PHR based Personal Health Care Service Platform. In this paper, we specify an ontology-based health data model for Personal Health Care Service Platform. We also design a knowledge search algorithm that can be used to figure out similar health record by applying machine learning and data mining techniques. Axis-based mining algorithm, which we proposed, can be performed based on axis-attributes in order to improve relevance of knowledge exploration and to provide efficient search time by reducing the size of candidate item set. And K-Nearest Neighbor algorithm is used to perform to do grouping users byaccording to the similarity of the user profile. These algorithms improves the efficiency of customized information exploration according to the user 's disease and health condition. It can be useful to apply the proposed algorithm to a process of inference in the Personal Health Care Service Platform and makes it possible to recommend customized health information to the user. It is useful for people to manage smart health care in aging society.

This study started with the question "Shall we apply the existing record management method to our trivial daily records?" For the general public, we focus on media that thinks more about daily recordings and suggests a better method, suggesting a 'social platform' as a plan, and using the user's visual approach through UX design methodology. The social archive proposed in this study aims to be a 'square' where various people can gather and communicate and share. A space that can record daily life using 'record' as a basic body Purpose It aims to provide the basis for basic research in various fields, and aims to function as a space for communication of various research things such as researchers and researchers, researchers and producers. In order to maintain, focus on the prerequisites of the existing construction, the items to be researched when constructing the daily archive are 'creative methodology to change research items when building a paradigm', 'network with related organizations', 'service plans for persistence', and characteristics of social media. We discussed the possibility of social media as a social archive platform. Finally, while looking at the user experience design process, I designed some features of the social archive and suggested things to do in UX design.

Objectives : This study was conducted to evaluate the effect of fixed critical pathway with emr (electronic medical record) on the length of hospital stay, the cost and quality of care provided to gastrectomy patients in a university hospital and to develop flexible critical pathway with emr which can be used excluded or drop-out patients. Methods : Thirty-eight patients with gastrectomy were included as case group and Thirty-four patients included as control group. The comparison between control and case with using fixed critical pathway were done. To develop and to evaluate usefulness of flexible critical pathway with flexible data base, simulation was done for flexible critical pathway with drop-out patients. Result : The major results of this study were as follows: There were no significant differences in patient clinical conditions and no sign of deterioration of quality from critical pathway. The length of hospital stay was 11 days in control group, 8 days in path group(P<0.01). The total costs during the hospital stay were reduced in path group. However the cost per day was significantly increased from reduction of hospital stay(554,352 won in control, 645,669 won in path group). One hundred percentage of drop out patients(60) in the simulation of flexible critical pathway was successful. Conclusion : Computerized critical pathway reduced the length of hospital stay, total hospital costs and resource utilization without harming quality of patient care. The flexible critical pathway program can be used as one of the powerful management tools for reducing the practice variations and increasing the efficiency of care process and decreasing the workload of doctors and nurses in Korean hospital settings.

Background: It is not possible to measure how much activity is required to understand and code a medical data. We introduce an assessment method in clinical coding, and applied this method to neurosurgical terms. Methods: Coding activity consists of two stages. At first, the coders need to understand a presented medical term (informational activity). The second coding stage is about a navigating terminology browser to find a code that matches the concept (code-matching activity). Systematized Nomenclature of Medicine - Clinical Terms (SNOMED CT) was used for the coding system. A new computer application to record the trajectory of the computer mouse and record the usage time was programmed. Using this application, we measured the time that was spent. A senior neurosurgeon who has studied SNOMED CT has analyzed the accuracy of the input coding. This method was tested by five neurosurgical residents (NSRs) and five medical record administrators (MRAs), and 20 neurosurgical terms were used. Results: The mean accuracy of the NSR group was 89.33%, and the mean accuracy of the MRA group was 80% (p=0.024). The mean duration for total coding of the NSR group was 158.47 seconds, and the mean duration for total coding of the MRA group was 271.75 seconds (p=0.003). Conclusion: We proposed a method to analyze the clinical coding process. Through this method, it was possible to accurately calculate the time required for the coding. In neurosurgical terms, NSRs had shorter time to complete the coding and higher accuracy than MRAs.

The sinking of the Sewol ferry has not only induced an intense conflict in Korean society but also been developed into a sociopolitical issue. This paper divides this accident into five stages and examines the records produced at each stage. The Sewolho Citizen Archive Network and the Ansan Citizen Record Committee began the archiving of Sewol and created the 416 Archives. The records of Sewol are social and political records that hold envidencial and historical value. They can be used to rebuild and recover the wounded community as well as to investigate the truth behind the case. Accident archiving collects materials different to the ones which public archiving does, allowing people to view the incident from a different standpoint. It is also characterized as an archiving of the current issue, social movement and regional community. Accident archiving is a method which ensures credibility and impartiality in memory. In light of Sewol archives, accident archiving can contribute to form mature democracy.

Recent business environments require a company to communicate frequently with other companies. This makes it essential to use XML (eXtensible Markup Language) documents for integration of information systems. Especially in e-Business environments, change management of documents is important to record and trace the history of the documents. In this paper, we propose a new method of storing a document by detecting changes automatically and reconstructing the document version when a user requests. In addition, based on the method, we also propose a model to recover a document into previous state even when system errors occur. A prototype system is implemented on top of a workflow system and an experiment is carried out to present efficiency of our method. Our approach provides efficiency of storage space and convenient management of documents.

The purpose of this study is to analyze the 7 principles of ISO 30300 and the requirements of ISO 30301 to provide the conceptual frame of MSR for various organizations providing a comprehensive understanding of the standard series. To achieve the aim of this study, we analyzed the relationship between 'ISO/FDIS 30300 MSR-Fundamentals and Vocabulary' and 'ISO/FDIS 30301 MSR- Requirements' using the Matrix Diagram approach. The results show that there exist some level of relationships between principles and requirement either directly or indirectly, however, 'Process approach' principle seems the closest relationship among them.

In this paper, we developed a Hospital Information System in which the business process is formalized and a wire/wireless integrated solution is used. This system consists of the administration office program, the medical office program, the ward management program and the rounds management program. The administration office program can enroll and accept patients, issue and reissue the RFID card. The medical office program inputs a medical examination and treatment, outputs a diagnosis, requests a hospitalization, retrieves the record of a medical examination and treatment, assigns the corresponding examination room to the accepted patients, and updates the number of an waiting patient and a patient number according to the examination room on real time. The ward management program handles hospitalizations and leaving hospital, a nurse's note, and an isolation ward monitoring. The rounds management program handles a medical examination and treatment, and a leaving hospital using PDA. This developed system can be built at low cost and increase the quality of the medical services highly by making it automated the medical administration automation. Also the small number of the medical staffs can manage the inpatients efficiently by using the monitoring functions.

Nowadays, new product development (NPD) is one of the most crucial factors for business success. The manufacturing firms cannot afford the resources in the long development cycle and the costly redesigns. Good product planning is crucial to ensure the success of NPD, while the Quality Function deployment (QFD) is an effective tool to help the decision makers to determine appropriate product specifications in the product planning stage. Traditionally, in the QFD, the product specifications are determined by a rather subjective evaluation, which is based on the knowledge and experience of the decision makers. In this paper, the traditional QFD methodology is firstly reviewed. An improved Hybrid Quality Function Deployment (HQFD) [MSOfficel] then presented to tackle the shortcomings of traditional QFD methodologies in determining the engineering characteristics. A structured questionnaire to collect and analyze the customer requirements, a methodology to establish a QFD record base and effective case retrieval, and a model to more objectively determine the target values of engineering characteristics are also described.
