Nowadays there are gradually the importance issues of embedded software for productivity as the fusion and complexity of industry. Especially, people are recognizing the importance of reliability within the embedded software systems(e.g. weapons and medical equipments, etc.). It makes currently mention of software reliability on ISO/IEC 9126, 12119, etc.. However, it is insufficient for the embedded software area in spite of being mentioned the generic software. To do this, we suggest our embedded software reliability assessment through extracting the embedded software meaurement items from reliability assessment items of ISO/IEC 9126, 12119 series.

This study aims to contribute to better understanding the effects of the changes in the parameter values of GroundFilter algorithm(GF), which performs filtering process, and of GridsurfaceCreate algorithm(GC), which creates regular grid, provided in Fusion software on the accuracy of elevation of the final LiDAR-DEM products through comparative analysis. In order to test whether there are significant effects on the accuracy of the final LiDAR-DEM products due to the changes of GF(1, 3, 5, 7, 9) parameter levels and GC(1, 3, 5, 7, 9) parameter levels, two-way ANOVA is conducted based on residuals. The residuals are calculated using the differences between each sample plot's paired field-measured and DEM-derived elevation values given each individual GF and GC level. After that, Tukey HSD test is conducted as a post hoc test for grouping the levels. As a result of two-way ANOVA test, it is found that the change in the GF levels significantly affects the accuracy of LiDAR-DEM elevations(F-value : 27.340, p < 0.01), while the change in the GC levels does not significantly affect the accuracy of LiDAR-DEM elevations(F-value : 0.457). It is also found that the interaction effect between GF and GC levels is not likely to exist(F-value : 0.247). From the results of the Tukey HSD test in the GF levels, GF levels can be divided into two groups('7', '5', '9', '3' vs '1') by the differences of means of residuals. Given the current conditions, LiDAR-DEM can achieve the best accuracy when the level '7' and '3' are given as GF and GC level, respectively.

의약품 추천 방법은 환자의 현재 건강 상태가 주어졌을 때, 해당 환자에게 효과적이면서도 안전한 의약품들을 추천해주기 위한 방법이다. 최근 의약품 추천 방법들은 환자에게 효과적이면서도 안전한 의약품들을 추천해주기 위해, 환자의 방문 정보(즉, 환자에게 진단된 질병, 수술 정보) 뿐만 아니라 의약품들 간의 (1) 동시 처방 여부 관계와 (2) 부작용 유발 관계를 추가적으로 활용하고 있다. 구체적으로, 이들은 의약품들 간의 두 관계를 각각 임베딩으로 나타낸 뒤 하나의 임베딩으로 융합하여 활용한다. 그러나 기존 의약품 추천 방법들은 이 두 임베딩을 융합하는데 있어서, 두 임베딩 간의 관계를 깊게 고려하지 않고 단순히 뺄셈 연산을 적용하고 있다. 따라서 본 논문에서는 실세계 데이터 집합을 활용하여, 의약품들 간의 두 관계에 대한 임베딩들을 다양한 방법을 통해 융합한 뒤각 방법이 추천 정확도에 어떠한 영향을 미치는지 비교 및 분석하여 더욱 정확한 의약품 추천을 제공하고자 한다.
