In this paper, we suggest a usage profiles for electric home appliances. In Korea, it is published the records for total consumption of electricity in a house but the electric home appliance consumption records in a households are not. To build the data, we must collect the usage of every appliances in a house and the information of the household which live in the house. Unfortunately, it is hard to get the data because of the worry about the breach of privacy. In this paper, we make a scenarios on the electricity consumption pattern of a few households type. Based on the conjecture, we make the power consumption profiles for some home appliances. Comparison to the total electric consumption records for a house, we found our scenarios are quite reasonable.

Since 2008, the General Archives Authority of Mongolia introduced management standards on international records, such as ISO 15489. GAAM translated the international standards and have trained government records managers with such standards. These international records management standards are also incorporated into the Mongolian records legislations and records management guidance. Complying with the standards are also the requirements for designing records management software in Mongolia.

Recently, The government has been brought in the electronic document system. So, It's been increasing the job processing with the electronic approval and the distribution business. However because of the variety of the storage type of electronic document, it's expected many difficulties in the public-usage and etemity-preservation of the information later. also, There are several problems to manage electronic document system, for example, absence of the important function for managing records, etc. So, We propose the methodology as a way to solve several problems of managing electronic document in this paper. It grows the business which is produced in processing the electronic records management. The kind of document file produced by the government is various. Through introducing the standard format of document file, hereafter it has an effect on helpfulness in standardizing the electronic document system, and people recognize the situation of problem to append the important function of the preservation and usage for the electronic document system. The key task is to make the document system with keeping records and following functions according to the law of records management. As applying the standard electronic document system to manage records, the records of the processing section to the data center and then the records of the data center transfer to the government records and archives center. So, the records which be transferred can be preservative and available. The record, such as visual and auditory record which is not easy to digitalize, can be digitally preservative and available in the government records and archives center.

This research is based on open data from the National Library Statistics System and Seoul Survey 2020 from Seoul to analyze the Seoul citizens' usage of public libraries. For such purposes, this research compared and diagnosed the condition of public libraries services at 25 districts of Seoul, focusing on objective indicators of library management and general usage records to understand the correlations between the two. Objective indicators such as budgets, human labor, the number of books, and total ground area were compared with usage records of different classes of Seoul citizens, organized by the citizens' place of living, educational background, and monthly household income. As a result of the research, the correlation between the objective indicators and public usage records of different classes was confirmed. Seoul citizens' usage of public libraries and reading tendency were identified. In addition to, a balanced development of the public libraries in Seoul was proposed to overcome regional disparities and leveling the service level by investigating usage behavior and reading tendency of the public libraries in Seoul.

Recently, predicting personality with the help of smartphone usage becomes very interesting and attention grabbing topic in the field of research. At present there are some approaches towards detecting a user's personality which uses the smartphones usage data, such as call detail records (CDRs), the usage of short message services (SMSs) and the usage of social networking services application. In this paper, we focus on the assessing the correlation between MBTI based user personality and the smartphone usage data. We used $Na{\ddot{i}}ve$ Bayes and SVM classifier for classifying user personalities by extracting some features from smartphone usage data. From analysis it is observed that, among all extracted features facebook usage log working as the best feature for classification of introverts and extraverts; and SVM classifier works well as compared to $Na{\ddot{i}}ve$ Bayes.

Time history analyses have been preferred commonly in earthquake engineering area to determine earthquake performances of structures in recent years. Advances in computer technology and structural analysis have led to common usage of time history analyses. Eurocode 8 allows the use of real earthquake records as an input for linear and nonlinear time history analyses of structures. However, real earthquake records with the desired characteristics sometimes may not be found, for example depending on soil classes, in this case artificial and synthetic earthquake records can be used for seismic analyses rather than real records. Selected earthquake records should be scaled to a code design spectrum to reduce record to record variability in structural responses of considered structures. So, scaling of earthquake records is one of the most important procedures of time history analyses. In this paper, four real earthquake records are scaled to Eurocode 8 design spectrums by using SESCAP (Selection and Scaling Program) based on time domain scaling method and developed by using MATLAB, GUI software, and then scaled and real earthquake records are used for linear time history analyses of a six-storied building. This building is modeled as spatial by SAP2000 software. The objectives of this study are to put basic procedures and criteria of selecting and scaling earthquake records in a nutshell, and to compare the effects of scaled earthquake records on structural response with the effects of real earthquake records on structural response in terms of record to record variability of structural response. Seismic analysis results of building show that record to record variability of structural response caused by scaled earthquake records are fewer than ones caused by real earthquake records.

Nowadays it is very necessary to generate artificial accelerograms because of lack of adequate earthquake records and vast usage of time-history dynamic analysis to calculate responses of structures. According to the lack of natural records, the best choice is to use proper artificial earthquake records for the specified design zone. These records should be generated in a way that would contain seismic properties of a vast area and therefore could be applied as design records. The main objective of this paper is to present a new method based on wavelet theory to generate more artificial earthquake records, which are compatible with target spectrum. Wavelets are able to decompose time series to several levels that each level covers a specific range of frequencies. If an accelerogram is transformed by Fourier transform to frequency domain, then wavelets are considered as a transform in time-scale domain which frequency has been changed to scale in the recent domain. Since wavelet theory separates each signal, it is able to generate so many artificial records having the same target spectrum.

The objective of this research is to search for measures to properly respond to the greatly increasing demands of complex information disclosure. At present, South Korea makes the deployment of records managers at public institutions mandatory through the Records Act. Records disclosure goes beyond simply deciding on the revelation and private usage of records, and requires the professionalism of institutions such as task knowledge and law-related knowledge. However, most records managers lack professionalism in the task of records disclosure despite achieving such in their regular work of managing records. As a countermeasure for such issues, this research is proposing the introduction of a series of exclusive charges in records disclosure named the Government Information Specialist, which professionally manages the records disclosure of the US government. In addition, to understand the demand of such, surveys and interviews of records managers who undertake both records management and records disclosure tasks at a South Korean public institution was also conducted.
