The recent H.264/AVC video coding standard provides a higher coding efficiency than previous standards. H.264/AVC achieves a bit rate saving of more than 50 % with many new technologies, but it is computationally complex. Most of fast mode decision algorithms have focused on Baseline profile of H.264/AVC. In this paper, a fast block mode decision scheme for P- slices in High profile is proposed to reduce the computational complexity for H.264/AVC because the High profile is useful for broadcasting and storage applications. To reduce the block mode decision complexity in P- pictures of High profile, we use the SAD value after $16{\times}16$ block motion estimation. This SAD value is used for the classification feature to divide all block modes into some proper candidate block modes. The proposed algorithm shows average speed-up factors of 47.42 ${\sim}$ 67.04% for IPPP sequences.

본 논문에서는 비트 패턴드 자기기록 저장장치 채널을 위한 2차원 변조부호를 제안한다. 패턴드 미디어 기록장치는 하나의 자성점에 한 비트의 정보를 저장한다. 정보저장 기록 밀도를 높이기 위하여 인접한 트랙 사이의 간격을 아주 좁게 만들기 때문에 인접한 트랙간 간섭(intertrack interference, ITI)과 인접한 심볼간 간섭(intersymbol interference, ISI)이 문제가 된다. 따라서 한 비트 신호의 진폭은 2차원 간섭에 의해 변형된다. 같은 값으로 둘러싸인 비트의 신호가, 특히 어느 한 비트의 값이 둘러싸인 여덟 비트의 값과 동일한 경우 영향을 받는다. 제안된 변조부호 방법은 기존의 변조부호보다 좋은 부호율을 가지면서 위와 같은 최악의 경우가 발생하지 않도록 하므로써 패턴드 미디어의 기록 성능을 향상시키도록 한다.

오늘날 원소스 멀티유즈(미국에서는 미디어 프랜차이즈라는 용어를 사용함)가 비주얼 콘텐츠 산업에서 시대의 흐름이 된 이유는 하나의 소스 콘텐츠를 가지고 다양하게 활용, 판매해 부가가치를 극대화 시킬 수 있기 때문이다. 이런 원소스 멀티 유즈가 성공하려면 메인이 되는 하나의 뛰어난 콘텐츠 개발 및 이를 다양한 장르에 접목시키는 기획력이 매우 중요하다고 할 수 있다. 본 논문에서는 이런 원소스 멀티유즈의 여러 성공 사례 중, 메이플 스토리를 중심으로 기획력 등 여러 요인을 분석하여 어떻게 한국에서 성공할 수 있었는지, 또한 한국형 원소스 멀티 유즈가 나아가야 할 점을 제안하도록 하겠다.

From 5 forest soil samples, the isolation frequency of oligotrophic Actinomycetes was investigated with nutrient and minimal media. The frequency of soil Actinomycetes by the minimal media. The frequency of soil Actinomycetes by the minimal media of DHV, WA, BA and NA was similar to the value by HV nutrient medium. In addition, different Actinomycetes were isolated from all the media used in this experiment and then their growth were tested on nutrient (Bennett's agar) and minimal media(WA). In consequent, the number of different Actinomycetes from minimal media was 26.1 strains, whereas the number of from nutrient medium (HV) was 26.6 strains. Furthermore, the percentage of facultative and obligate strains among the oligotrophic Actinomycetes was 90% and 10%, respectively.

The emergence and development of innovative science and technology is changing lives at a rapid pace with the expansion of human perception. The development of the media extends the scope of activities of the body and the mind, realizing the imagination and challenging the limits of experience. In this process, the transformation of media into new forms such as disassembly, merging, and fusion have emerged that have resulted in the emergence of transmedia. In recent years, the fashion industry has responded quickly to trends and is actively engaged in transmedia communication activities. Among them, Gucci's media utilization strategy has attracted interest in the millennial generation. This study examines the strategy of transmedia storytelling by concentrating on the case of Gucci among luxury fashion brands that utilize media effectively in various aspects. It reveals the aspect of how the use of transmedia can be used to enjoy the story of fashion content and spread its value.

This study applies in case of operating an exam using by the contrast order or inputting an order of a contrast media the exam of Radiology Department. It is developed for helping decision making as regards a process of an exam from reading the creatinine value automatically linked with Laboratory Information System. It can be confirmed by real-time information; therefore, the creditability of the information is able to be improved. We will create the base for Patient Monitoring System with the data from the side effect of the creatinine value and allergies. Decision Support System minimize the inconvenience and the riskiness of the given contrast medium for CT tests. We would like to improve medical services by providing a standard circumstance where patients are able to run tests safely and comfortably.

The 200mesh screen was tensioned and fixed on a frame. When applied tension to 5N and 10N per unit area, a side length of opening of the screen was 163.223${\mu}m$ and 168.224${\mu}m$, respective. But side length not tensioned was 158.879${\mu}m$. We knew that a side length of opening of the screen rarely changes with tension applied to the screen. The appearances that a side length of opening of the screen expand little are due to a decreasing diameter of thread by means of tension. In a thickness measurement of screen, While the high density mesh screen that had a lot of knots that crossed a line of latitude and longitude per unit area appeared a higher numerical value, the low density mesh screen that had a few knots appeared a low numerical value.

Nowadays, our societies use digital technology in new architectural shape and space design to transcend three dimension limit so the boundary of the imagination world and actuality world has been collapsed. Traditional spatial value has been collapsed. Also indetermination and temporary assumption in time, fluidness and dematerialized, simultaneity and reiteration in image are relative with this circumstances. In architectural shape, media characteristics which secede from traditional characteristics of place tectonic value have occurred. Therefore, indifference and interests in shape, inter-permeation in interior and exterior space, homogeneous equivalence spatial extension have occurred. The purpose in this study examines dematerialized in contemporary space design and light materials and also investigates general and architectural background. The results of this study are as follows. First, circumstances of human have changed from physically limited boundary to unfixed, nonphysical, lightness and vague things. Second, casting off volume in shape and also dissembling exclusive and constructive Third, interior and exterior space by transparency intimates media possibility of information screen. Fourth, seek information and organic response, ambivalent transformation, accumulation of image and new mutual understanding system.

본 연구는 비접촉식 센서 기반의 웨어러블 디바이스를 이용한 딥러닝 기반의 제스처 인식에 대한 연구이다. 이를 위하여 Flexible MSG 센서를 기반으로 한 Flexible Epidermal Tactile Sensor를 사용하였으며, Flexible Epidermal Tactile Sensor는 손, 손가락 제스처를 취했을 때 손목, 손가락과 연결되어 있는 근육들의 움직임에 따라 발생하는 피부 표면의 전극을 취득하는 센서이다. 실험을 위하여 7가지 손, 손가락 제스처를 정의하였으며, 손목의 꺾임, 손목의 뒤틀림, 손가락의 오므림과 펴짐, 아무 동작도 취하지 않은 기본 상태에 대한 제스처로 정의하였다. 실험 데이터 수집에는 손목이나 손가락에 부상, 장애등이 없는 일반적인 8명의 참가자가 참가하였으며 각각 한 제스처에 대하여 20번씩 반복하여 1120개의 샘플을 수집하였다. 입력신호에 대한 제스처를 학습하기 위해 본 논문에서는 1차원 Convolutional Neural Network를 제안하였으며, 성능 비교를 위해 신호의 크기를 반영하는 특징벡터인 Integral Absolute Value와 Difference Absolute Mean Value를 입력신호에서 추출하고 Support Vector Machine을 사용하여 본 논문에서 제안한 1차원 CNN과 성능비교를 하였다. 그 결과 본 논문에서 제안한 1차원 CNN의 분류 정확도가 우수한 성능을 나타냈다.

To characterize gene expression that is dependent on the strength of calorie restriction (CR), we obtained transcriptome at different levels of glucose, which is a major energy and carbon source for budding yeast. To faithfully mimic mammalian CR in yeast culture, we reconstituted and grew seeding yeast cells in fresh 2% YPD media before inoculating into 2%, 1%, 0.5% and 0.25% YPD media to reflect different CR strengths. We collected and characterized 160 genes that responded to CR strength based on the rigorous statistical analyses of multiple test corrected ANOVA (adjusted p value < 0.1 or raw p value < 0.0031) and Pearson correlation (|r| > 0.7). Based on the individual gene studies and the GO Term Finder analysis of 160 genes, we found that CR dose-dependently and gradually increased mitochondrial function at the transcriptional level. Therefore, we suggest these 160 genes are markers that respond to CR strength and that might be useful in elucidating CR mechanisms, especially how stronger CR extends life span more.
