BCH code is one of the most widely used error correcting code for the detection and correction of random errors in the modern digital communication systems. The conventional BCH encoder that is operated in bit-serial manner cannot adequate with the recent high speed appliances. Therefore, parallel encoding algorithms are always a necessity. In this paper, we introduced a new systolic array type BCH parallel encoder. To study the area and speed, several parallel factors of the systolic array encoder is compared. Furthermore, to prove the efficiency of the proposed algorithm using tree-type structure, the throughput and the area overhead was compared with its counterparts also. The proposed BCH encoder has a great flexibility in parallelization and the speed was increased by 40% than the original one. The results were implemented on synthesis and simulation on FPGA using VHDL.

Arthrospira platensis (A. platensis) is a microscopic and filamentous cyanobacterium that derives its name from the spiral or helical nature of its filaments. In this study, we induced mutants of A. platensis through NMU treatment and selected two strains by level of ipid contents. We named mutant '1-9', '2-5', and they were cultivated in the same way with the wild type. During 12 days cultivation, cell growth, dry cell weight, pigment content, and lipid content were measured for characteristics of mutants. As a result, pigment and lipid content of mutants were increased about 3.6, 1.8 times compared with wild type, respectively. It was shown that total flavonoid and polyphenol contents of mutants were increased about 1.5 times compared with wild type. And radical scavenging effect of mutants were increased about 10% compared with wild type.

In this paper, we describe a concept-based question-answering system in which concept rather than keyword itself makes an important role on both question analysis and answer extraction. Our idea is that concepts occurred in same type of questions are similar, and if a question is analyzed according to those concepts then we can extract more accurate answer because we know the semantic role of each word or phrase in question. Concept frame is defined for each type of question, and it is composed of important concepts in that question type. Currently the number of question type is 79 including 34 types for person, 14 types for location, and so on. We experiment this concept-based approach about questions which require person s name as their answer. Experimental results show that our system has high accuracy in answer extraction. Also, this concept-based approach can be used in combination with conventional approaches.

This paper compares presentation methods which are characteristic among museums of natural history in Korea. The different medium for exhibitions are divided into Specimen, Model or Panel Type Displays, Video Presentations, Sound, and Tactile Exhibits, and further classified as Fixed (A Type), Observable (B Type), or Performance Art (C Type) Displays. The museums we studied were the Seodaemun Museum of Natural History, Ewha Womans University Museum of Natural History, Seoul National Science Museum, Gyeryongsan Natural History Museum, the National Science Museum, Mokpo Natural History Museum, and the JejuDo Folklore and Natural History Museum. A study of these museums' approaches to display composition, and exhibition methods according to their exhibit types and contents, revealed the following results: The museums of natural history rely more on Fixed type displays to show information, with appropriate uses of the Observable and the Performance Art type exhibitions. Better utilization of appropriate medium is desired for display contents of Astronomy Space Earth, Minerals Rocks Geology, Animals, Plants, Insects, Prehistoric Organisms Environment, and Anthropology.

To investigate relationships of electronic taste-traits with muscle fiber type composition (FTC) and contents of nucleotides, porcine longissimus lumborum (LL), psoas major (PM), and infra spinam (IS) muscles were obtained from eight castrated LYD pigs. FTC and taste-traits in these three porcine muscles were measured by histochemical analysis and electronic tongue system, respectively. IS had significantly higher proportion of type I fibers while LL had significantly higher proportion of type IIB than other muscles (p<0.05). IS had the highest inosine monophosphate (IMP) content while LL had the lowest IMP content (p<0.05). In contrast, LL had significantly higher hypoxanthine content compared to PM and IS (both p<0.05). For taste-traits, IS had significantly higher umami and richness values but lower sourness value than LL and PM (p<0.05). Sourness and astringency values of LL were significantly higher than those of IS (p<0.05). The proportion of type IIB fiber was positively correlated with sourness and astringency but negatively correlated with saltiness. These results suggest that sourness and astringency tastes are increased with increasing proportions of type IIB fibers in porcine muscles due to increase of hypoxanthine content. These results also imply that umami and richness tastes are increased with increasing contents of type I and IIA fibers because of increased IMP content in porcine muscles.

It is very important to educate students who can be working professionals in contents-related field. This paper discusses three types of contents academic-industrial cooperation projects which are contents technology, contents software and education, and contents-making projects. Regarding third type, this paper explains two examples of contents-making projects that Daejeon University's Animation Department did. First one is Miznco Co.'s in 2015 and second one is which exhibition is held in old provincial of Chung-nam and Skyroad[1] at Daejeon in 2016. This exhibition is held for reviving old town area of Daejeon which is called one-do-sim through great contents. This paper also proposes what contents-related department in each university has to do to survive in tough period.

김치용 결구배추를 겉잎(L1), 중잎(L2), 속잎(L3)으로 세 등분하여 부위별로 일반성분을 포함한 이화학적인 성분을 측정하여 비교하였다. 조단백질 및 조지방 함량은 겉잎(L1)이 높았고, 조회분 및 탄수화물 함량은 속잎(L3)이 높았다(P<0.05). 열량은 24.5~26.5 kcal/100 g이었고 부위별로 유의적인 차이가 없었으며, 총식이섬유는 겉잎(L1)이 가장 높았다(P<0.05). 유리당은 fructose, glucose, sucrose가 확인되었으며, 속잎(L3)에서 fructose 및 glucose 함량이 높았다(P<0.05). 유기산은 citric acid, malic acid, succinic acid가 검출되었으며, citric acid와 malic acid 함량은 속잎(L3)이 높았고 succinic acid는 겉잎(L1)이 높았다(P<0.05). 총유리 아미노산의 30% 이상을 차지하는 glutamic acid 함량은 속잎(L3)에서 높았으며, ${\gamma}-aminobutyric$ acid의 함량은 겉잎(L1)이 가장 높았다(P<0.05). 결구배추 잎의 주요 미네랄 성분은 K, Na, Ca, Mg이며, 이 중 K의 함량이 가장 높았다. 총미네랄 함량은 겉잎(L1)이 가장 높았다(P<0.05). 결구배추 잎은 부위에 따라 이화학적 성분 조성이 다른 특성을 가지므로 신선편의 식재료로서 활용성이 더욱 증대될 수 있을 것으로 생각한다.
