이동객체는 시간에 따라 공간 객체의 위치 및 영역이 연속적으로 변경되는 시공간 데이터이다. 기존의 데이터베이스 시스템을 이용하여 시공간 이동 객체를 관리할 경우 다음의 두 가지 문제점을 가진다. 첫째, 시간에 따라 변화되는 위치 정보에 대한 빈번한 갱신이 발생된다. 둘째, 항상 객체의 현재 상태만이 저장되므로 시공간 이동 객체의 과거와 미래에 관한 정보를 제공하지 못한다. 따라서, 이 논문에서는 빈번한 갱신없이 이동 객체의 이력 정보를 관리할 뿐만 아니라 과거, 현재 그리고 가까운 미래에 관한 모든 위치 정보를 제공할 수 있는 시공간 이동 객체 관리 시스템을 제안한다. 제안 시스템에서 이동 객체 정보는 위치를 나타내는 위치정보와 이동 습성을 나타내는 행위 정보로 구분된다. 특히, 행위정보 변경 처리 알고리즘을 사용하여 최소한의 이력 정보만으로도 모든 객체의 위치 정보를 검색할 수 있는 방법을 제안한다. 그리고, 제안한 방법을 전장 분석 시스템에 적용하여 구현하였으며, 이를 통해 관계형 데이터베이스와 GIS 시스템을 이용하여 실세계의 시공간 이동 객체의 과거 , 현재 및 가까운 미래의 위치 정보를 관리할 수 있음을 알 수 있었다. Moving objects are spatiotemporal data that location and shape of spatial objects are changed continuously over time. If spatiotemporal moving objects are managed by conventional database system, moving objects management systems have two problems as follows. First, update for location information changed over time is occurred frequently. Second, past and future information of moving objects are not provided by system because only current state of objects is stored in the system. Therefore, in this paper, we propose a spatiotemporal moving objects management system which is able to not only manage historical information of moving objects without frequent update, but also provide all location information about past, current, and near future. In the proposed system, information of moving objects are divided into location information for representing location and motion information for representing moving habits. Especially, we propose the method which can search location information all objects by use of changing process algorithms with minimum history information. Finally, we applied the proposed method to battlefield analysis system, as the result of experiment, we knew that past, current, and near future location information for moving objects are managed by relational database and GIS system.

지오폴리머의 반응성은 원재료의 구성성분 및 Si/Al비, Na/Al비, 물-결합재비, 비정질 요소 등을 고려하여 명확한 메커니즘을 규명하는 것은 매우 중요하다. 따라서 원재료 및 알칼리 활성화제의 구성성분을 고려한 %Na<sub>2</sub>O, Ms는 반응성을 결정하는 중요한 요소가 된다. 하지만 다수의 연구에서는 알칼리 활성화제의 농도와 양생 조건 등의 기본적인 요소만을 고려하는 한계점을 나타내고 있다. 따라서 본 연구에서는 %Na<sub>2</sub>O, Ms 및 고로슬래그 미분말의 혼입량에 따른 지오폴리머 페이스트의 강도특성, 반응열, 길이변화, 미세구조 분석을 실시하였다. The addition of a limestone filler(LF) to fill into the voids between cement and aggregate particles can reduce the cementitious paste volume. In previous studies, it has been found that the addition of LF to reduce the cementitious paste volume would substantially increase the compressive strength, and reduce the heat generation. This paper aim to evaluate the influence of LF contents on the hydration kinetics and compressive strength. Hydration kinetics were evaluate using heat of hydration, ignition loss and thermal analysis. The heat of hydration was measured using Isothermal Calorimetry. The degree of hydration was measured using ignition loss. Hydration product analysis was carried out by Thermal Gravimetric and Differential Thermal Analysis. The results show that the addition of LF reduces not only the initial setting time and heat of hydration peak, also degree of hydration and rate of strength development at early age increase with the addition of LF. It can be concluded the LF fills the pore between cement particles due to formation of carboaluminate, which may accelerate the setting of cement pastes.

본 논문은 운동기구에 장착할 수 있는 와이파이 모듈을 이용하여 운동시 운동량에 대한 데이터를 스마트기기에 전송할 수 있는 관리 모듈을 개발한다. 본 연구에서는 스틱(Stick)형 운동기구를 대상으로 운동기구에서 측정되는 운동량을 센서에서 측정한 후 무선통신을 통해 스마트 기기에 데이터를 보낸다. 스마트 기기에서는 사람별로 분류화된 데이터 목록에 운동량 데이터를 저장하여 추후 사용자에게 과거에 운동한 기록들을 보게 해준다. 제작된 앱(App)은 안드로이드와 iOS에서 모두 동작할 수 있도록 제작되었으며, 성능평가의 결과로서 내환경 시험 및 전자파 인증 시험을 외부전문기관의 챔버내에서 진행하여 성능을 만족함을 확인하였다. 개발된 운동량관리 모듈은 다양한 형태의 운동기구에 적용 가능하여 추후 많은 확장성을 갖는다. In the paper, we propose a method for developing a physical training management module which sends physical data to smart devices using an wireless module attached to physical appliances. In the proposed stick-type physical appliance, the physical amount of data measured from sensors inside the appliance is sent to a smart device via wireless communication. And then the smart device records the physical amount of data categorized in person-based data and shows useful information about the user"s physical training on the dedicated display. For the performance evaluation, indoor environment and electro magnetic wave tests are taken from national specialized organizations, and their results was very efficient. The proposed physical training management module is highly extensible since it is easily applicable to other physical appliances and useful to both Android and iOS platforms.

Purpose: The study sought to provide basic information for North Korean defectors (Sae-Tu-Min) by studying the quality of life(QoL) based on their general characteristics and health problems. Methods: The targeted subjects were 1400 North Korean settlers who were receiving settlement service by Korean National Red Cross after finishing their training at Hanawon in 2005. The data was collected from August to October in 2007. The QoL was assessed by Medical Outcomes Study Short Form-36. Collected data were analyzed by ANOVA and t-test with SPSS win 15.0 program. Result: The majority of the 466 subjects were female(77.9%). The average age was 36.8 years, 52.8% lived alone, and 64.0% were unemployed. The average QoL score of the group was 62.4 ±18.4, which was markedly lower in terms of social, physical and mental health compared to the scores of immigrants to South Korea from other countries. The score was the highest for physical ability and the lowest for general health. Influential socio-demographic factors to QoL were gender, age, education, religion, annual salary, occupation, and life insurance. Employed in the subject group showed higher level of QoL on eight categories than unemployed. Concerning health problems that detracted from QoL, 18.5% of the subjects were aware they suffered from anemia and 8.8% of them recognized they suffered from attention deficits. Conclusion: The health conditions of the North Korean settlers had improved since they settled in South Korea, but their QoL was lower than other immigrants. Various programs to maintain and promote the health of North Korean settlers would be useful.

This paper presents the results of an experimental study on the influence of nano-silica in the relative humidity and autogenous shrinkage in hardening cement mortar. The water-binder ratio was used 0.3 and two types of mortar were used in this study; mortar made with ordinary portland cement and ordinary portland cement with 3, 7, 10% nano-silica added. The increased autogenous shrinkage, as a consequence of a reduction of relative humidity at early ages.
