With the ready access to the high resolution satellite image data, users of and areas covered by satellite image data are constantly on the rise world-widely. Korea will also be able to take full advantage of the satellite data once the Korea Multi-Purpose Satellite 1 (KOMPSAT-l) is successfully launched. Harmonizing satellite data production and application technology and users' needs, along with the guiding policy is essential for promoting satellite data use. Up to now, the Korean government has mainly concentrated on developing production technology for the satellite instruments. However, the imminent task of independent satellite data production demands a promotion policy for satellite data use. In this context, the policy is defined as an important medium for identifying the role and status of satellite image information at the national level and also preparing the legal as well as systematic foundation for producing, building, distributing, and packaging satellite data. The present paper aims to examine the role and status of the satellite data as well as their current status and problems in Korea in reference to the National Spatial Data Infrastructure, and finally to provide the policy directions to promote the satellite data use in public sector on the basis of the preceding analyses.

In this study, annual site and primary energy use intensities (EUIs) and $CO_2$ emission intensities (CEIs) per area by end use were estimated based on the measurement data from June 2016 to May 2017 of 19 sample office buildings in Seoul. In addition, the estimated site EUIs by end use were compared to the U.S. Commercial Buildings Energy Consumption Survey (CBECS) 2012 data. Average site EUIs by end use were found to be in the order of electric appliance (typical floors) > heating > cooling > lighting > air movement > domestic hot water > vertical transportation > city water supply. In the case of primary EUIs and CEIs by end use, electric appliance was found to be the largest. As results of comparison with the CBECS 2012 data, it was found that the site EUIs were similar for heating, cooling, domestic hot water, and electric appliance, etc., but slightly different for lighting and air movement. The number of sample office buildings will continue to increase until 2020 (total number of samples 85) and intensities data by end use will be continuously updated through continuous collection of measurement data.

This paper started from a question: Can it help a student solve the problem to give supports in point of view of a teacher knowing the solution. We performed a case study to get an answer for the question. We analysed a case which students do not make full use of data in the mathematical problem from this point of view of the mental representation. We examined closely the cause for not making full use of data. We got that the wrong mental representation which the students get from data in the problem lead to not making full use of data. We knew that it is insufficient to present the data not making use of. To help a student truly, it is necessary to give a aid based on a student's mental representation. From the conclusion of study, We got that figuring out student's mental representation is important and hope that many investigation about student's mental representation for various problem occur with frequency.

The impact of the detailed surface data on regional meteorological fields in complex coastal area is studied using RAMS. Resolutions of topography and land use data are very important to numerical modeling, because high resolution data can reflect correct terrain height and detail characteristics of the surface. Especially, in complex coastal region such as Gwangyang area, southern area in Korean Peninsula, high resolution topography and land use data are indispensable for accurate modeling results. This study investigated the effect of resolutions of terrain data using SRTM with 3 second resolution topography and KLU with 1 second resolution land use data. Case HR was the experiment using high resolution data, whereas Case LR used low resolution data. In Case HR, computed surface temperature was higher than Case LR along the coastline and wind speed was $1{\sim}2m/s$ weaker than Case LR. Time series of temperature and wind speed indicated great agreement with the observation data. Moreover, Case HR indicated outstanding results on statistical analysis such as regression, root mean square error, index of agreement.

Purpose The purpose of this study is to investigate the intention of early application users in consideration of the characteristics of digital finance-based MyData service users. It is expected that user characteristics will affect the intention to use MyData service, which has not yet been advanced, and accordingly, it will examine how the characteristics of the initial users of MyData service and the intention to use it are connected. Design/methodology/approach The model used in this study is a value-based adoption model (VAM), and a lot of research has been conducted on information technology and online user acceptance and continuous use intention of online users. VAM has been proven useful through empirical analysis in many studies. The value-based acceptance model is a method of analyzing the intention to use Benefits and Sacrifices as the main elements of perceived value. It can be said to be a model that can analyze the benefits of use and the sacrifices to be made. Findings According to the analysis results of this study, it was found that usefulness, enjoyment, and reliability, which are the benefits of MyData service apps, had a positive effect on perceived value, which is partially consistent with existing research results. However, it was found that complexity, which is the sacrifice of MyData service apps, negatively affects perceived value and security has no negative impact. The results of security are considered to be complementary to financial institutions because MyData service deals with financial data based on personal information, and the research hypothesis is rejected because users' demands are relatively low. Therefore, MyData service apps should do more to increase benefits (usefulness, enjoyment, and reliability) than to reduce sacrifice (complexity) to users.

본 연구는 지형도면 고시 및 등재 절차에서 발생하는 용도지역지구 데이터의 오류 유형과 원인을 밝힘으로써 데이터 정비방안을 마련하는데 목적을 두고 있다. 우리나라는 미국과 같은 규정중심의 토지이용규제방식이 지배적이다. 즉 법령 내 토지이용규제방식에 따라 정부는 전국의 모든 필지에 용도지역지구 지정과 행위제한 사항을 두고 있으며, 토지소유자들은 국토이용정보체계를 통해 내 토지의 토지이용규제사항을 확인하게 된다. 더 나아가 토지이용계획확인서는 개인 간의 토지거래나 개발행위허가와 같은 행정처분의 결과에 영향을 미치는 중요 토지정보임을 확인할 수 있다. 그러나 현재의 지형도면고시를 통해 토지이용규제정보가 생산되는 절차와 데이터의 구축 과정에서 발생되는 데이터 오류들이 존재한다. 이에 본 연구에서는 지자체 여건을 고려해 유형별로 데이터 실증 가능한 4개 지자체를 선정하였고, 분석을 위한 데이터를 수급하고 오류 검정 방법을 수립하여 수행한 결과 어떤 유형의 데이터 오류가 많고, 발생 원인이 무엇인지를 진단하였다. 다수의 오류는 첫째, 분산된 시스템 환경에서 실제 지형도면 고시 결과와 시스템의 데이터가 다르게 표기되는 등 국토이용정보체계 내 데이터 구축 및 관리상의 오류이고, 둘째, 지형도면고시 작성 지침 내 검수 기준과 절차가 마련되어 있지 못하고 민간업체 위탁으로 데이터 정비를 하면서 발생하는 전문성 부족의 오류, 셋째, 베이스 맵으로 사용되고 있는 연속지적도와 용도지역지구DB와의 관계성에서 오는 오류로 분석되었다. 이상의 결과들을 바탕으로 데이터 정비방안들을 제시하였고, 이러한 결과들이 「제3차 국토이용정보체계 구축계획」 수립 이후 현재 진행되고 있는 국토이용정보플랫폼(KLIP)의 구축과 법제도 개편하는 과정에서 반드시 고려되어야 할 것이다.
