This paper studies medical data classification methods, comparing decision tree and system reconstruction analysis as applied to heart disease medical data mining. The data we study is collected from patients with coronary heart disease. It has 1,723 records of 71 attributes each. We use the system-reconstruction method to weight it. We use decision tree algorithms, such as induction of decision trees (ID3), classification and regression tree (C4.5), classification and regression tree (CART), Chi-square automatic interaction detector (CHAID), and exhausted CHAID. We use the results to compare the correction rate, leaf number, and tree depth of different decision-tree algorithms. According to the experiments, we know that weighted data can improve the correction rate of coronary heart disease data but has little effect on the tree depth and leaf number.

The main purpose of this study is to analyse and evaluate the metadata elements of 'Records System' and 'Electronic Document System' specifications for Korean government agencies based on functional requirements of ISO 15489. This present paper begins with discussing the characteristics of recordskeeping metada, and extract the metadata elements fulfilling the ISO 15489 functional requirements. And this study tries to compare the metadata elements of current specifications with ISO 15489 elements. Based on these analyses, it suggests the directions for improving current metadata specifications and for developing national metadata standard.

A discussion on false alarm is a series of problems about a waste of police resources. The the false alarm primarily increase machine the cost of security firm but ultimately increase the costs of national and social management. Verified Report System has been in operation since July 1, 2013, We could analyze the actual operation of 112 report on false alarm rate was 82.4% before this system launched, but after implementation of the Verified Report System, this rate level downs below 69.7% records. So 12.7% is declined at the rate of false alarm. However, the actual alarm rate of Electronic Security itself is just only 0.3 % in the total number of cases responding in contrast to Police is considerable. It is more urgent to evolve the Verified Report System, so penalty system against the false alarm, Police registration system of sensors, and strengthening of the task of the company for installation and management of detection equipment are urgently needed.

It is an important role of a researcher to preserve the research process and results as a record in the overall R&D from the planning stage to completion. This can be used as a basis to support the objectivity of the R&D process and results. This can be used as a basis to support the objectivity of the R&D process and results. The necessity of writing research notes is raised in terms of research ethics, records management, intellectual property rights protection, and research results protection according to 「National Research And Development Innovation Act」. Therefore, in this paper, the results of the systematic and practical management method of research notebooks operated by government-funded institutions are described.

This article intends to provide a direction for reconstructing the national regime of archival appraisal in electronic record environments. Functional appraisal, which inevitably carries out for appraising electronic records, has defects in aspect of selecting archives important in a national point of views. To do so, this article discusses defects of functional appraisal, and then suggests the necessity of archival appraisal strategies that complements functional appraisal. To investigate this archival appraisal strategies, it analyzes Australia's Whole-of-Government Functional Analysis, United Kingdom's Acquisition Policy and Appraisal Policy, Germany's Cooperative Cross-Archives Appraisal and Canada's Macro Appraisal. Ultimately, this analysis is able to establish a base of the regime of archival appraisal which will harmonize primary value at current stage with secondary value at non-current stage in a national point of views.

Applying evolved IT technology to increase the satisfaction of the consumer is a typical feature of the rapidly transformed service industry. Smart devices have taken a place as the mainstream of major media, moreover, IT service strategies utilizing smart devices have been constantly developed. Location recognition method of users has been proposed as one of the significant features to the IT service industry. The long-term care home services can be one example of user location recognition methods that real time computerization of service record utilize an attached tag to home of pensioners with RFID reader or an NFC function of mobile when a home carer provides service. And, the Homecare Electronics Management System (HEMS) and the various location recognition methods will be discussed to improve effectiveness of services. In this paper, we propose a home applicable electronic management system which insurer, home care service facilities, home cares, pensioners and guardians which enables to simultaneously check service records based on the improved system by use of iBeacon.

This study investigated the perceived significance of laboratory(lab) notebooks and the creation and maintenance of them from the perspectives of graduate students and professors in science fields. Semi-structured interviews of three professors and four graduate students were conducted. The interviewees were from three university laboratories of physics, chemistry and biological science. While professors perceived administrative continuity to be a reason for creating lab notebooks, students valued lab notebooks as a memory, and emphasized learning professional knowledge and skills through the recordkeeping practice. Students understood the ownership of lab notebooks and professors wanted to keep lab notebooks until they retire. Interviewees focused more on the content of lab notebooks rather than the form and the structure. They were also not willing to adopt an electronic lab notebook system. Students learned how to create lab notebooks through a course, their current or former academic advisors, seniors in the lab or well-written sample lab notebooks. In particular, students have learned how to create lab notebooks within their laboratories, which are considered to be communities of practice. In this sense, professors responsible for managing laboratories play an important part in teaching students the recordkeeping practice. University archives should also be more concerned with managing and preserving lab notebooks created from their universities.

It can be said that digital technology is at the center of the change in the modern work environment. In particular, in general public institutions that prove their work with records produced by business management systems and document production systems, the record management system is also the work environment itself. Gimpo City applied for the 2021 public cloud leading project of the National Information Society Agency (NIA) to proactively respond to the 4th industrial revolution technology era and implemented a public cloud-based AI-OCR technology enhancement project with 330 million won in support of 330 million won. Through this, it was converted into data beyond the limitations of non-electronic records limited to search and image viewing that depend on standardized index values. In addition, a 98% recognition rate was realized by applying a new technology called AI-OCR. Since digital technology has been used to improve work efficiency, productivity, development cost, and record management service levels of internal and external users, we would like to share the direction of enhancing expertise in the record management and implementation of work environment innovation.

The purpose of this study is to propose effective management plan for official seal guaranteeing authenticity of archival records. For this, this paper attempts to investigate current management conditions of central governments and National Archives. First, disclosure of information on official seal register in central government was requested. In addition, surveys and interviews with person in charge were carried out. Additionally, official seal lists of National Archives were analyzed and the person in charge was interviewed. Based on these, this paper proposed management plans of official seal such as a periodic inspection of management conditions, training programs for the person in charge, selective acquisition, reporting of the current state, improvement of law system, improvement of document formats, and establishment of an electronic seal management system, etc.
