In spite of the R&D level of Korea, the efforts to protect the R&D results from outflowing has not been raised up. We investigated the current status of security education and the level of researcher's awareness for research security in the government-financed institutes. Also, we attempted to find out the needs for institutionalization of the security education. We conducted a survey and in-depth interviews of all the security officers in the thirty-seven government-financed institutes. The results show that the awareness level of the researchers for R&D security is below adequate level, and that security education is necessary in order to increase the security awareness. Also, it is necessary to institutionalize the security education.

Generally, learning tools like robots are being mainly used as teaching aids to enhance creativity of a group of students who are superior in their studies and have an excellent potential in private education. This study uses a relatively cheap line tracer as a teaching aid and connects it with regular subjects so that elementary school higher graders showing academic achievement lower than average can get robot learning. This research developed a line tracer learning curriculum and teaching materials for total 12 sessions and taught students showing academic achievement below average and evaluated them after. According to the result of evaluating their achievement levels based on their results of learning in each session, most of the students with low academic achievement was evaluated to understand most of the contents in the curriculum fully. Through its empirical implementation, this paper has found the possibilities of robot education connected with the regular curriculum for elementary students exhibiting relatively lower academic achievement.

Information and communication brings us some degree of convenient but also serious side effects. Especially, information and communication ethics is an important issue for elementary school children who are early stage in moral value. This paper proposes a triple-connected teaching and learning model. which can be applied to the elementary school children. in order to improve the educational level. The model is formed by selecting three discretionary teaching models, and applying independently them into the different classes with linking the contents for each class. A teacher can choose the teaching models based on what he wants to teach. Caring model, Home-Connected model and Simulation model were linked in our experiment. Experiments were conducted in the same condition but different learning models, Then, an educational effect was compared and analyzed in the educational level improvement point of view, between the Triple-connected teaching and learning model and the single teaching and learning model.

To address the requirements of gap analysis for species protection, as well as the needs of state and federal agencies for detailed digital land cover, a 43-class map at the vegetation alliance level was created for the state of Kansas using multi-temporal Thematic Mapper imagery. The mapping approach included the use of three-date multi-seasonal imagery, a two-stage classification approach that first masked out cropland areas using unsupervised classification and then mapped natural vegetation with supervised classification, visualization techniques utilizing a map of small multiples and field experts, and extensive use of ancillary data in post-hoc processing. Accuracy assessment was conducted at three levels of generalization (Anderson Level I, vegetation formation, and vegetation alliance) and three cross-tabulation approaches. Overall accuracy ranged from 51.7% to 89.4%, depending on level of generalization, while accuracy figures for individual alliance classes varied by area covered and level of sampling.

The purpose of this study is to examine the effects of family affluence on happiness and to investigate the mediating effects of self-rated health on the relationship between family affluence and happiness. This study was conducted to analyze the data which were derived from 8th(2012) of the online census on youth health behavior conducted by the Ministry of Disease Control and total subjects were 74,168. The result of this study is that social-economy is regarded as a little poor. On the other hand, subjective health is regarded as a good and they generally satisfied with life. The relationship between family affluence, happiness, and self-rated health, family affluence level is linked to happiness and self-rated health, and self-rated health has positive effects on the level of happiness. That is, it was verified that self-rated health has a partial mediation effect on the way that family affluence influences happiness. Based on the results of study, the followings are suggested: the impact of socioeconomic disparities on health disparities needed to be decreased; The efforts of the social dimension, health policy formulation and execution of multi-dimensional which is to increase happiness should be implemented.

This study aims to explore how to improve students' rights based on their age and development stages. To this end, we analyzed a survey that had been carried out with 1,065 students from elementary, middle and high schools in 2 most populated counties in Korea, focusing on the differences in their perception with regard to the right to survive, develop, be protected and participate. The result of the analysis showed that high school students' sense of rights was at the lowest in general, while being particularly low in their sense of participation rights. However, when it comes to the development rights and protection rights, the level of recognition of middle school students were as low as those of high school students. Based on the results, we suggested that a proactive effort to guarantee adolescents' participation rights is required, and that education of human rights should be emphasized not only for children but also for their supporters. In the follow-up study, it is required to investigate the differences between development stages and regions by including participants with diverse ages and residential areas.

As a system becomes more complex, a design relies more heavily on a methodology based on high-level abstraction and functional verification. SystemVerilog includes characteristics of hardware design language and verification language in the form of extensions to the Verilog HDL. However, the OOP of System Veri log does not allow multiple inheritance. In this paper, we propose adoption of SystemC to introduce multiple inheritance. After being created, a SystemC unit is combined with a SystemVerilog-based verification environment using SystemVerilog DPI and ModelSim macro. Employing multiple inheritance of SystemC makes a design of a verification environment simple and easy through source code reuse. Moreover, a verification environment including SysemC unit has a benefit of reconfigurability due to OOP.

In this paper, an efficient prediction accuracy enhancement strategy is proposed for improving the performance of the prediction-based parallel event-driven gate-level timing simulation. The proposed new strategy adopts the static double prediction and the dynamic prediction for input and output values of local simulations. The double prediction utilizes another static prediction data for the secondary prediction once the first prediction fails, and the dynamic prediction tries to use the on-going simulation result accumulated dynamically during the actual parallel simulation execution as prediction data. Therefore, the communication overhead and synchronization overhead, which are the main bottleneck of parallel simulation, are maximally reduced. Throughout the proposed two prediction enhancement techniques, we have observed about 5x simulation performance improvement over the commercial parallel multi-core simulation for six test designs.

본 논문에서는 분포형 강우-유출 모형인 GRM(Grid based Rainfall-runoff Model)의 확장성과 편의성 향상을 위한 소프트웨어 개발에 대해서 기술하였다. 본 연구에서는 크게 3가지를 수행하였다. 첫 번째는 기존의 GRM은 HyGIS, MapWindow GIS 등과 같은 GIS 소프트웨어 및 Microsoft MDB와 코드 수준에서 통합된 형태로 개발되었으며, 이러한 특성은 GRM을 이용한 다양한 응용시스템 개발시 제약 조건으로 작용하였다. 본 연구에서는 GRM 모형을 GIS 및 데이터베스와 코드 수준에서 분리하여 GRMCore.dll을 개발하였다. GRMCore.dll은 콘솔 모드 및 GUI에서 유출해석을 실행할 수 있는 소프트웨어와 실시간 유출해석시스템 등과 같이 유출 해석을 위한 다양한 응용 소프트웨어 개발에 공통적으로 활용될 수 있다. 두 번째는 최근 들어 세계적으로 가장 많이 사용되고 있는 오픈소스 GIS 인 QGIS의 plugin으로 GRM 모형의 GUI(QGIS-GRM)를 개발하였으며, GRM 모형의 입력자료 구축을 위해 TauDEM을 이용해서 Drainage Tool을 개발하였다. Drainage Tool에서는 격자별 흐름방향, 하천망, 유역 등과 같은 수문학적 공간정보를 DEM을 이용하여 구축할 수 있다. 세 번째는 개발된 소프트웨어를 오픈소스로 공개하였다. 공개 대상은 GRM 모형, QGIS-GRM, Drainage Tool 등이며, 각 소프트웨어에 대한 매뉴얼을 포함하고 있다. 소스코드의 공개는 세계적으로 널리 이용되고 있는 오픈소스 플랫폼인 Github(https://github.com/floodmodel/)를 이용하였다. 본 연구를 통해서 기존에는 특정 소프트웨어에 코드 수준에서 의존적이던 GRM 모형의 독립성을 향상시켰으며, 이를 통해 다양한 응용 소프트웨어 개발에 대한 적용성을 높일 수 있었다. 또한 QGIS 기반의 GUI 개발, 모형 입력자료 구축 도구의 개발, 개발된 소프트웨어의 오픈소스화 등을 통해서 사용자들이 좀 더 쉽게 GRM 모형을 활용할 수 있게 하였다.

This study aims to examine the difference in the level of housing cost burden and the factors affecting housing cost burden between permanent rental housing and purchased rental housing residents in Seoul. We used the 2017 SH Public Housing Resident Survey and employed t-test and multiple regression analyses. The empirical analysis shows that the level of housing cost burden is greater for permanent rental housing residents than purchased rental housing residents. Also, income level, age, and whether receiving housing benefits are the factors affecting housing cost burden among permanent rental housing residents while income level and housing size are the factors affecting housing cost burden among purchased rental housing residents. The findings suggest that there should be a more systematic review regarding housing affordability among those living in different types of public housing toward housing welfare. In addition, there should be differential approach to enhance housing affordability between permanent and purchased rental housing residents.
