  • Ajax(Asynchronous JavaScript and XML)를 이용한 표준 기반의 웹 응용프로그램 개발로 플러그인(Plug-In) 방식의 비표준 웹이 특정 브라우저에 종속적이지 않은 환경으로 변화하였다. 그러나 Ajax 타일지도는 몇 가지 한계점이 있으며 이러한 문제를 해결하기 위해서 본 논문에서는 새로운 HTML5 표준과 인코딩 된 data-URL을 이용하여 레스터웹 지도 서비스에 활용될 수 있는 공간정보 전송 및 저장기법을 제안한다.

  • 영상 기반 모델링 및 렌더링을 위해 제안된 LDI(Layered Depth Images) 기법은 여러 장의 2차원 영상과 깊이 정보, 카메라 정보를 입력으로 받아 3차원 와핑을 이용해 새로운 장면을 렌더링한다. 하지만 이 기법은 홀 발생 문제 등 몇가지 결함을 가지고 있다. 본 논문은 이러한 LDI의 문제를 해결하고자, 의료 영상 가시화 분야에서 널리 사용되는 쉬어-왑 렌더링 알고리즘을 사용한 결과를 설명한다. 한편, 본 논문에서 제안된 알고리즘은 적은 데이터를 필요로 하는데, 웹 상에서 오브젝트 플레이어 플러그인으로 개발한 결과 좋은 성능을 보였다.

  • In this study, We made Computing Stories as a part of the new method of SW education. Also, we have developed unplugged activities using coding stories. We analyzed changes in learning motivation and academic achievement in the core concepts of CT by applying classes to elementary school students. For the development of coding stories, we conducted a questionnaire analysis of 11 expert groups to derive the core concepts of computational Thinking. Using the core concept of Computational Thinking, we developed a coding stories and unplugged activities linked with coding stories. It was confirmed that the score of the core concept of CT before and after class increased from 54.44 to 83.10 and the learning motive was also improved from the average score of 103.48 to 110.44. The results showed that the Coding Stories were effective in the students' Computational thinking achievement and SW learning motives.

  • The simulation-based weapon system effectiveness analysis is to support the decision making in the acquisition process of the defense domain. The effectiveness of the weapon system is a complexly influenced indicator from various factors such as environment, doctrine and so on. And the measurement of effectiveness can be defined differently in compliance with major issues in the weapon system. Because of this, the weapon system effectiveness analysis requires the comparative experiment of various alternatives based on the underlying assumption. This paper presents the efficient approach to reconfigure the simulation using the reflection technique. The proposed method contains the recoupling and resetting the simulation entity using DEVS(Discrete EVent System specification) formalism-based dynamic plug-in method. With the proposed method, this paper designs the effectiveness analysis environment that can efficiently handle the various alternatives of the weapon system.

  • The effect of useful rhizobacterium added in bed soil on the early growth promotion of red pepper plug seedlings was investigated. Total 540 colonies of rhizobacteria from 385 samples of eggplant family roots were isolated. Among these, 5 isolates were selected for antifungal activity against pathogenic fungi such as Alternaria solani, Botrytis cinerea, Fusarium oxysporium, Phytophthora capsici, and Sclerotia sclerotiorum. Of all the isolates, MJ-3 having the most pronounced growth-promoting ability for red pepper was finally selected and identified as Bacillus amyloliquefaciens through characterization of biochemical and bacteriological aspects and 16S rDNA sequence. The plant height, stem diameter, root length and fresh weight of red pepper plants which were grown with inoculation of B. amyloliquefaciens MJ-3 were higher than those without inoculation. Especially the root weight of the inoculated red pepper plant increased by 44.3%, the content of endogenous plant hormone (CA$_1$) being 0.556 ng/g (dry weight).

  • Software compliance is an essential process when Open Source Software is included in software development to avoid such as license violation issue. However, analyzing quite big software which involves many developers requires enormous time and hard difficulty. To resolve these kinds of problem, SPDX formalizes and standardize the metadata about the software package. When the use of SPDX is activated, software package analysis would be simple and could contribute fair Open Source Software distribution. In this paper, we develop blockchain based SPDX distribution platform which fulfills the requirement of SPDX lifecycle to provide SPDX database which does not depend on particular centralized service but serve as distributed ledger and control by user's certification and their purpose. Moreover, to contribute invigoration of blockchain based SPDX distribution platform, we develop SPDX document generation plug-in for integrated development environment such as Visual Studio.

  • This research was conducted to investigate the influence of various pre-planting $NO_3:NH_4$ ratios in the coir dust+peatmoss+perlite (3.5:3.5:3, v/v/v) medium on the growth of tomato plug seedlings (cv. Dotaerang Dia), changes in chemical properties of root media, and tissue nutrient contents. With the fixation of N concentration to $300mg{\cdot}L^{-1}$, the $NO_3:NH_4$ ratios were adjusted to 100:0, 73:27, 50:50, 27:73, 0:100. Then, root media containing various $NO_3:NH_4$ ratios and equal concentration of other essential nutrients were filled into 50-cell plug trays and the seeds of 'Dotaerang Die' tomato were sown. The investigation of seedling growth and tissue analysis for mineral nutrient contents based on the dry weight of above-ground tissue were conducted 6 weeks after sowing. As seedlings grew, the EC decreased quickly and pH increased gradually in the all treatment media. The plant height, fresh weight and dry weight of seedlings in the treatment of 50:50 ($NO_3:NH_4$) were 29.0 cm, 13.7 g, and 1.21 g, respectively, which were the highest among treatments tested. However, the seedlings in the treatment of 0:100 ($NO_3:NH_4$) had 26.5 cm, 11.2 g, and 0.92 g in plant height, fresh weight and dry weight, respectively. These were the poorest among the treatments tested. The tissue contents of N were 2.77 to 3.22% in all the treatments. The treatment of 27:73 ($NO_3:NH_4$) had the highest contents of Fe, Mn and Zn and that of 0:100 ($NO_3:NH_4$) had the lowest contents of Mg, Na, Cu, Mn and Zn among the treatments tested. The results indicate that $NH_4$ ratio should be lower than 50% in the coir dust+peatmoss+perlite (3.5:3.5:3, v/v/v) medium for seedling growth of tomato and the optimum ratio will be used to draw up guide lines for plug seedling production.

  • There are growing demands for improving the patient safety and the effectiveness of medical services through device connectivity and interoperability. However, integration through networking might greatly increase the complexity of the system if it is not properly designed, jeopardizing patient safety. In this paper, we codify safe medical device interaction patterns, and exploit them for the low complexity design and safety analysis of networked supervisory medical systems. We implement the proposed approach as a plug-in of Architecture Analysis and Description Language (AADL). Our implementation enables the modeling and safety analysis of medical devices and their interactions before actual development.

  • Recent technologies of the car are focused on improving vehicle's fuel efficiency and developing alternative energy sources. These technologies bring on the development of hybrid car. On the other hand, because of short driving distance, low efficiency of charging and high price, energy storage system need to improve the storage capability. It is very important to understand the existing technologies, grasp the existing patent and establish the technical target to improve the energy storage system. In this paper, technology trends of energy storage system of the hybrid car are analyzed. This study was based on the applied and registered patent in Korea, Japan, U.S.A and Europe until December 2008. The analyses are divided into two categories: a battery system and charging system of the hybrid car. The facts of the level of technology, trends of the R&D of leading companies, key patents, blank of the technology were analyzed. Finally the future R&D strategy of hybrid car are established.
