The plastic arts is used when designers draw inspirations to create fashion design. The author referred to fashion magazines for designing ideas of Mondrian＇s geometrical abstract painting in practical applications used by designers in Paris, Italy, London and New York during the 10-year period(1991-2000). The collections of data were analyzed as following: ◇ Fashion Designing Idea 1. Matching Idea The art is reproduced in the design as how it is with no transformation. First, the painting＇s complete figure is reproduced on the entire or parts of clothing. Second, the painting＇s partial figure is reproduced on the entire or parts of clothing. 2. Contrasting Ideas The composition elements in Mondrian＇s geometrical abstract painting, for example, structures of shapes, vertical and horizontal lines and different colors are applied in the design. First, one particular shape in painting is transformed into different shape of square, circle or triangle and reproduced in designing. Second, one particular shape in painting is disassembled and then reshaped into different form in reproduction. Third, additional lines are put in to create different look from the original painting. Forth, existing lines are extended over the boundary to create different look from the original painting. Fifth, achromatic colors: black and white, and three basic colors: red, blue and yellow in the original painting are modified into different shades or color scheme is increased in broad range.

본 논문에서는 투영된 모션과 히스토그램 인터섹션을 이용한 노이즈에 강건한 물체추적 방법을 제안한다. 기존의 방법은 템플릿 매칭, 물체의 경계선 재 검출, 물체의 움직임 정보 등을 사용하여 물체추적을 하였으나, 템플릿 매칭의 경우 많은 계산 시간을 요구하며 경계선을 재 검출하는 경우 윤곽선이 잘못 설정되는 경우가 있고 물체의 움직임 정보를 사용하는 경우에는 움직이는 카메라에서 움직이는 물체만을 추적하기가 쉽지 않은 단점이 있다. 본 논문에서는 투영된 모션과 질의 영상의 템플릿 마스크를 사용하여 물체의 이동, 회전과 스케일을 고려한 노이즈에 강건한 물체추적 기법을 제안한다. 질의영상은 영상분할 후 영역선택을 통하여 구성하고 물체의 인식은 색상을 이용한 히스토그램 인터섹션 기법을 사용한다. 물체의 이동은 가로 및 세로의 밝기 값을 1차원 신호로 투영하여 개략적인 움직임을 감지하고 이동에 대한 에러를 보정하며 회전과 스케일의 변화는 질의 영상의 템플릿 마스크를 이동하여 회전과 스케일에 맞게 변경하여 감지한다

현재의 NATM터널에 대한 물량은 설계도면을 기반으로 산출되는데, 이러한 방법은 수작업에 많이 의존하게 되므로 실수로 인한 물량의 오류와 사람의 능력에 따른 물량의 차이가 나타나게 된다. 본 연구는 BIM기반의 모델에서 자동적으로 물량을 산출하여 물량산출의 오류나 차이점을 바로잡고 설계변경에 따른 물량산출작업을 효율적으로 수행하려는 프로젝트에 필요한 BIM 모델링을 통한 물량산출 프로세스의 가이드라인을 제시한다. 또한, 여러 BIM 프로그램들은 각각의 모델링 및 물량산출 방식을 가지고 있어서 하나의 프로세스로 통합하기 어려운 문제가 있기 때문에 본 연구에서는 Autodesk사의 Revit Structure에 적합한 작업 프로세스에 대한 가이드라인을 제시하며 NATM 터널의 전체 구간이 아닌 본선구간만을 대상으로 한다. 본 연구는 전체적인 NATM 터널의 BIM기반 물량산출 모델링 프로세스를 BIM 모델링과 BIM 물량산출로 분리하였다. BIM 모델링 프로세스는 물량산출의 대상과 범위 설정, 모델링을 위한 CAD도면 작성, 패밀리 파일의 설정, 공종별 모델링 작업으로 구성된다. 물량산출의 대상과 범위 설정 단계에서는 NATM 터널의 CAD 파일과 수량 산출서를 분석하여 물량산출을 위한 공종별 물량산출 범위를 확정하고, 도면에 표시되지 않는 물량정보를 파악하여 물량 값을 정확하게 산출할 수 있도록 하며, 모델링을 위한 CAD도면 작성 단계에서는 Revit Structure 특성을 고려하여 모델링에 참조하는 CAD 도면을 Revit Structure에서의 모델링에 적합하게 편집해야한다. 그리고 패밀리 파일의 설정과 공종별 모델링 작업 단계에서는 CAD도면과 Revit Structure의 패밀리 파일과의 단위를 일치시키고 NATM 터널의 특성에 맞게 공종별 모델링을 실시한다. BIM 물량산출 프로세스는 모델링 데이터의 분할, 패밀리의 재구성, 물량산출로 구성된다. 모델링 데이터의 분할단계에서는 물량산출의 목적에 맞게 CAD에서 기준선을 작성하여 공종별 모델링이 작성된 패밀리 파일로 불러온 다음 모델을 분할해야한다. 그리고 패밀리의 재구성과 물량산출단계에서는 분할된 공종별 모델의 패밀리 파일을 프로젝트 파일로 불러온 다음 물량산출의 목적에 맞게 재배치하여 물량을 산출한다.

This paper introduces segmentation based environment modeling method and integration method using multiple environment map for constructing the realtime image-based panoramic navigation system. The segmentation-based environment modeling method is easy to implement on the environment map and can be used for environment modeling by extracting the depth value by the segmentation of the environment map. However, an environment model that is constructed using a single environment map has the problem of a blurring effect caused by the fixed resolution, and the stretching effect of the 3D model caused when information that does not exist on the environment map occurs due to the occlusion. In this paper, we suggest environment models integration method using multiple environment map to resolve the above problem. This method can express parallax effect and expand the environment model to express wide range of environment. The segmentation-based environment modeling method using multiple environment map can build a detail model with optimal resolution.

Rabin fingerprinting used for chunking requires the largest amount computation time in data deduplication, In this paper, therefore, we proposed parallel Rabin fingerprinting on GPGPU for efficient data deduplication. In addition, for efficient parallelism in Rabin fingerprinting, four issues are considered. Firstly, when dividing input data stream into data sections, we consider the data located near the boundaries between data sections to calculate Rabin fingerprint continuously. Secondly, we consider exploiting the characteristics of Rabin fingerprinting for efficient operation. Thirdly, we consider the chunk boundaries which can be changed compared to sequential Rabin fingerprinting when adapting parallel Rabin fingerprinting. Finally, we consider optimizing GPGPU memory access. Parallel Rabin fingerprinting on GPGPU shows 16 times and 5.3 times better performance compared to sequential Rabin fingerprinting on CPU and compared to parallel Rabin fingerprinting on CPU, respectively. These throughput improvement of Rabin fingerprinting can lead to total performance improvement of data deduplication.

The Korea Stewardship Code 'Principles on the Fiduciary Responsibilities of Institutional Investors' was introduced in 2016 and the National Pension Service adopted it in 2018. the National Pension Service casted 'dessent' vote on the agenda which is able to reduce the ownership interest of shareholder in general meeting. This paper examines whether 'dissent' voting affected on the ownership interest of shareholder or not. The 'dissent' vote on the agenda are related to revision artical of corperation, appointment or compensation of director and auditor, approval of financial statements ect. The proxies of earnings management is discretionary accruals calculated by modified Jones model. The control variablies are size of assets, liabilities per assets, returns on assets. The results of this study are as followings. First, the 'dissent' voting on the agenda are related to revision artical of corperation, M&A, approval of financial statements ect. are not significant because their sample size is too small, Second, the 'dissent' voting on appointment of director and auditor affected on reduction of discretionary accruals. So the National Pension Service activism shall affect on increasing the ownership interest of shareholder. Third, the 'dissent' voting on compensation of director and auditor is not affected on reduction of discretionary accruals. This results show that 'unconditional dissent voting' on the agenda in general meeting is not to reduce the ownership interest of shareholder.

This study is a spatial analysis of the boundaries related to the division of the Korean peninsula. The boundary space was extracted by extracting $38^{th}$ parallel and digitizing the map of the Armistice Agreement Annex. The purpose of this analysis was to extract more accurate scope based on the armistice agreement, the appendices, and the UNC regulations and to analyze the wrong information correctly. The range of demilitarized zones was determined by UNC 551-4(2014) and UNC 551-5(2015) to ensure that there is no change in the location of the Southern Limit Line. It also confirmed that the MACHA was excluded in the DMZ. As a result, the area of the DMZ was measured at $889.7km^2$. Also this study identified the interval and number of markers in the MDL and the Han River estuary. It could be confirmed that the interval of markers within the MDL depends on the subject of management. This study is more accurate from the start and can be used as basic data needed in the study and education of DMZ and border areas after verification by public organizations.

In study, we investigated changes on growth and chlorophyll concentration on sprouted barley by fractionated X-ray irradiation (FXI). Group was divided into the control group (CG), 1-time irradiation group (30 Gy once), 2-time irradiation group (15 Gy 2 times), and 3-time irradiation group (10 Gy 3 times), and 20 grains were used per group. Experimental group (EG) was exposed by using linear accelerator (Clinac IS, VERIAN, USA), by 6 MV X-ray, SSD 100 cm, 18×10 cm², 600 MU/min. Length was measured every day until 9th day, and chlorophyl was analyzed using spectrophotometer(uv-1800, shimadzu, japan) in 9th day. Data analysis was performed the One-way ANOVA using SPSS ver 26.0(Chicago, IL, USA). In the pre-germination irradiation group (Pre-GIG), the CG had greater length than the EG on all measurement days, and as the number of FXI increased, the length became shorter. In the post-germination irradiation group (Post-GIG), the length of the CG was statistically significantly greater than that of the EG on all measurement days, and as the number of FXI increased, the length also became longer. The chlorophyll concentration was higher in the Post-GIG than in the Pre-GIG, and chlorophyll concentrations of EG was higher in the Pre-GIG than in the CG, as well as and Post-GIG. In addition, the smaller the number of FXI, the higher the chlorophyll concentration in both groups. FXI was found to affect the growth and chlorophyll concentration of sprouted barley.

Optical power optimization of 10 Gbps 40 wavelength division multiplexing channels was analyzed at the 3000 km long-haul transmission distance when the link span distance was changed between 40 km and 140 km. The signal performance of the transmission was obtained as a Q value and it was compared when input power into SSMF and input power into DCF on the transmission link were changed. The optimized input power into SSMF increased linearly to link span distance with 1 dB/km. The optimized power into DCF increased linearly with 0.5 dB/km up to 100 km link span, but it had no variation at longer link span than 100 km.
