Leading of the computer, IT technology has make great strides. As a information-industry-community was highly developed, user's needs to convenience about intelligence and humanization of interface is being increase today. Nowadays, researches with are related to BCI are progress put the application-technology development first in importance eliminating research about fountainhead technology with DB construction. These problems are due to a BCI-related research studies have not overcome the initial level, and not toward a systematic study. Brain wave are collected from subjects is a signal that the signal is appropriate and necessary in the experiment is difficult to distinguish. In addition, brain wave that it's not necessary to collect the experiment, serious eyes flicker, facial and body movements of an EMG and electrodes attached to the state, noise, vibration, etc. It is hard to collect accurate brain wave was caused by mixing disturbance wave in experiment on the environment. This movement, and the experiment of subject impact on the environment due to the mixing disturbance wave can cause that lowering cognitive and decline of efficiency when embodied BCI system. Therefore, in this paper, we propose an accurate and efficient brain-wave DB building system that more exactness and cognitive basis studies when embodied BCI system with brain-wave. For the minimize about brain wave DB with mixing disturbance, we propose a DB building method using an automatic control and prevent unnecessary action, put to use the subjects face tracking.

Recently, two international standard organizations, ISO and OGC, have done the work of standardization for GIS. Current standardization work for providing interoperability among GIS DB focuses on the design of open interfaces. But, this work has not considered procedures and methods for designing GIS DB. Eventually, GIS DB has its own model. When we share the data by open interface among heterogeneous GIS DB, differences between models result in the loss of information. Our aim in this paper is to revise the design guidelines for geographic information databases in order to make consistent spatial data models, logical structures, and semantic structure of populated geographical databases. In details, we propose standard guidelines which convert ISO abstract schema into relation model, object-relation model, object-centered model, and geometry-centered model. Furthermore, we provide sample models for applying these guidelines in commercial GIS S/Ws. Building GIS DB based on design guidelines proposed in the paper has the following advantages: the interoperability among databases, the standardization of schema definitions, and the catalogue of GIS databases through.

This paper surveyed and analyzed cases of DB development overseas to set the range of DB to be developed for analyzing energy-saving policies in the domestic transportation sector. The foregoing prerequisites were used to establish system for classification in the broad scale under which system for classification in detail indicators that suit one in the broader indicators was set based on analysis of domestic / overseas cases to determine DB development range in the transportation sector required to analysis domestic energy-saving policies. Accordingly, six items subject to the broadest classification were determined, i.e. energy consumption, energy basic unit, emissions of greenhouse gas, economic indicators, transportation volume / transportation records and basic automobile data. Large classification and sub-items determined by surveying expert opinions were set and proposed as DB classification indicators.

우리나라의 물관련 정보와 관련된 시스템은 국토해양부 및 관련 기관에서 다양하고 폭넓게 고유의 업무성격에 맞춰 구축 및 운영, 개발 중에 있으며, 이러한 시스템들은 치수, 이수, 환경 및 생태 등 다양한 정보를 제공하고 있다. 그러나 치수적 측면에서 제방관리를 위한 다양하고 구체적인 정보취득이 어렵고 기구축된 시스템의 DB간 상호 연계가 어려운 실정이다. 현재 IT 산업의 급격한 발전으로 다양한 분야에 스마트폰 어플리케이션의 활용이 이루어지고 있으며 이러한 추세는 수자원분야의 정보화 환경에 도움을 줄 것이다. 본 연구에서는 제방관리를 위한 도구로서 스마트폰 어플리케이션을 활용하고자 한다. 국내에서 수행하고 있는 사업인 하천일람의 "하천이력관리체계", 유역조사사업의 "WAMIS", 하천정보를 제공하고 있는 "RIMGIS"의 관련자료를 분석함으로서 제방제원 및 관리정보의 DB를 구축하고 어플리케이션에 활용한다. 제방 명칭, 행정구역별, 하천별, 수자원단위지도별 조회가 가능하도록 하여 국가홍수관리시스템 구축 및 대국민정보제공 활용 및 관리기술 개발에 기여할 것으로 판단된다.

지방자치단체(이하 지자체)는 경제, 사회, 문화 등 다양한 분야의 지표 및 데이터를 관리하고 있다. 지자체의 데이터를 수집하여 분석하고자 하는 사회과학 분야 연구자들은 이렇게 지자체별로 흩어져 있는 관련 데이터를 수집하는데 많은 시간과 노력을 투여하고 있다. 만약 지자체의 경제, 사회, 문화 등 관련 지표를 통합적으로 제공하는 데이터베이스가 구축되고, 이를 다양한 기법으로 검색할 수 있는 시스템에 구축된다면, 사회과학분야 연구자들에게 많은 도움이 될 것이다. 본 연구는 지난 5년 동안 구축한 지자체 통합데이터베이스(이하 통합DB)에 대하여 소개하고, 통합DB를 활용하여 구축한 경제, 사회, 문화 지표 통합 검색 시스템에 대하여 소개하고자 한다.

In recent years, developed countries have begun to pay attention to female workers through work-family balance in order to solve the problem of low fertility and aging. Korea has been building and running a women leaders database (hereafter, women leaders DB) centered on the female professionals since 2011. In particular, the Incheon women leader DB, which was built by Incheon city in 2009, is a classic example. As of 2015, about 2,735 people are registered in Incheon Women Leaders DB and it is systematically creating the database such as age, education, career years, major, occupation, and certification. However, there are administrative problems such as unspecified definition on professionalism and data trust issues including data entry, and DB personnels are concentrated in specific fields. Also, in the case of certification proving expertise, the utilization problem has been revealed including inclusion of private certification not yet verified. In order to solve these problems, we first need to clarify the concept of women leaders and establish the standard. The second is the improvement of data consistency through DB reorganization, and third is to build a system through continuous and active public relations that is used by both job seekers and recruiters.

In this study, the establishment strategies of Military Standardization Information System and Integrated Database(DB) based on standardization information are provided. The establishment strategies introduced here are based on the appliable common(commercial and military) classification of specifications/standards. The common(commercial and military) classification of specifications/standards adapted in this study can be constructed through mapping by 'grouping' between the MS(Military Specification/Standards) and KS(Korean industry Standards) to increase efficiency. In detail, the establishment of Integrated Database(DB) based on standardization information provides the various channel of interactive communication among specifications/standards. Additionally, standardization information systems provide the basis of the integrated specifications/standards converged between the commercial and military sector.
