This paper presents a mobile color-compensating application using a RGB color compensation algorithm. The proposed application enables color vision deficiencies to differentiate images which cannot be distinguished by them. The suggested mobile application has two functions: converting images taken by camera and converting contents in the device screen. The proposed application is computationally inexpensive, since it does not require color space transformation. Simulation results show that the proposed application enables color vision deficiencies to receive information expressed by colors such as subway line maps.

Application sharing is the ability to use existing applications, such as Excel or MS-Word, during a group session without modification. In this paper, we present the design and implementation of an application sharing system, called ShareIt, which enable users to share arbitrary MS-Windows applications under the Win 3.1/95/NT and X window system, and evaluation of the system performance. To share an application, the image of the application window is captured and transmitted to other sites. With the use of the window capturing method, ShareIt allows any MS-Windows application to be shared regardless of not only the window systems but also the version-up of window systems.

맥류후작 콩 재배시 보릿짚의 시용효과를 구명하기 위하여 보릿짚 시용, 제거 및 소각에 따른 토양 이화학성 및 콩의 생육과 수량에 미치는 영향에 대하여 검토하였던 바를 요약하면 다음과 같다. 1.보릿짚을 시용한 토양의 유기물함량은 보릿짚 제거 및 소각보다 높았으며 수분을 등 물리성의 개선 효과 있었다. 2. 잡초발생은 보릿짚 제거에 비해 보릿짚 시용에서 44%, 소각에서 31% 억제되었다. 3. 근류수 및 근류 건물중은 보릿짚 시용에서 많았다. 4. 식물체 건물중은 보릿짚 시용에서 지상부는 파종 후 30일경까지는 보릿짚 제거에 비해 적었으나, 그 이후단계는 차이가 없었으며, 지하부는 전 생육기간 동안 보릿집 처리 방법에 따른 차이는 없었다. 5.수량은 보릿짚 처리방법에 따른 유의적인 차이는 없었다.

The soil organic matter contents in arable land are generally low in Korea. Thus it is generally agreed that the application of organic materials to soils would be much beneficial. Present paper is a review on the effectiveness of organic mat ter application in uplands and lowlands. 1. The effect of organic matter application in uplands are of more clear and simple to explain as compared to that in lowlands. In uplands, appropriate application of organic matters such as compost and various crops residues improves the physical properties of soils leasing to increased water holding capacity, better aeration, and decrease in soil erosion. 2. In lowland, rice soils under water logged conditions the effect of organic matter application on rice yield is not straight borward and demands more refined knowledges for the interpretation of it. 3. It is found that the application of compost in rice soils is more effective when nitrogen fertilizer application is limited it dicating that nitrogen contained in the organic maerials can become available to rice plant and plays an important role for increased yield of rice under the condition where nitrogen fertilizer supply is limited. 4. Application of organic matter does not always bring about the desirable effects. Very often the organic matter application results in more intensive soil reduction leading to the accumulation of harmful substances which would can cancel out the positive effects of organic matter. This is partiunlarly true in poorly drained soils. 5. Rice straw or compost, when applied rice soils, supply sizeable amounts of available silicate to rice plant resulting in yield increase. 6. Although the effectiveness of organic matter application on rice yield in short term experiments is not consistent due to many reasons, the long term effect of organic matter is significant. 7. The term of the $O.M/SiO_2$ ratio in rice soils can serve as a criterion for the judgement of whether organic matter or silicate fertilizer is needed to be applied in a certain soil.

This paper presents a preliminary analysis result on SAR-related journal papers published since 1960s. Abstracts of more than 2700 peer-reviewed English journal papers were collected and classified into various categories according to their systems, techniques, and application fields. Statistics on each category were provided so that one can understand historical and on-going development in SAR systems, techniques, and a variety of application fields such as land, ocean, cryosphere and atmosphere. This statistical data would be an essential guideline to establish a future SAR system application and satellite manoeuvring policy.

This experiment was carrid out to investigate the effect of organic fertilizer and plant growth regulators application on the growth and quality of tomato. The results are summarized as follows. 1. Plant height of tomato was recorded highest when chemical fertilizer plus organic fertilizer was applied, and did not have significant effects in number of leaf. But stem diameter was positively effected by chemical plus organic fertilizer application than chemical fertilizer alone. 2. Flower formation, flower weight, anther weight and ovary weight were generally increased by organic fertilizer application. 3. Fruit-set and number of flower were significantly increased by organic fertilizer application. 4. Deformity fruit was the lowest rate at chemical plus organic fertilizer application when it was 14.7 percent, and it was increased by chemical fertilizer application. 5. Days of ripening was slightly delayed by organic fertilizer application and also flowering date shortened by chemical fertilizer application. 6. Plant growth regulators had positive effects on number of flower, flower weight, anther weight, and ovary weight, and variations of their effect by cluster were apparent. 7. Fruit-set was increased by 2,4-D 10ppm and BA 20ppm treatments but was decreased by treatments of Ethephon 10ppm and control. 8. By the BA 20ppm and 2,4-D 10ppm treatments, the rate of deformity fruit was decreased and fruit ripening date was also shortened.

최근 휴대용 기기들이 대중화되어 한 사람이 하나 이상의 휴대용 기기를 소지하고 있고 스마트폰 활용도 또한 늘어나는 추세이다. 스마트폰이 많이 보급됨에 따라 폭발적으로 스마트폰의 애플리케이션 활용이 늘어나고 있다. 현재의 애플리케이션 스토어는 플랫폼별로 애플리케이션을 개발해줘야 하는 종속적인 면이 있다. 앱스토어는 크게 애플의 앱스토어와 구글의 안드로이드 마켓으로 양분되어 있고 각 플랫폼에 맞춰 애플리케이션이 개발되어야 한다. 각각의 플랫폼에 맞춰서 애플리케이션을 개발하면 개발 비용은 2배에 근접하고 다른 소규모 플랫폼(Ex 바다)들은 애플리케이션 개발자들을 모아야만 자신들의 플랫폼에 맞는 애플리케이션이 나오는 단점이 있다. 이러한 플랫폼에 맞춰서 개발된 네이티브 애플리케이션의 범용성에 대한 해결책과 모바일에서의 다양한 요구사항을 수용하기 위해 웹 애플리케이션이 각광받고 있다. 웹 애플리케이션은 플랫폼에 종속되지 않고 어느 휴대용 기기에서도 동작하기 때문에 각 플랫폼별로 개발하지 않아도 된다는 장점이 있다. 따라서 웹 애플리케이션 스토어끼리의 연동 프로토콜을 통해 애플리케이션을 연동하여 어느 웹 애플리케이션 스토어에서도 볼 수 있고 특정 플랫폼에 구애받지 않는 거대한 시장이 생겨날 수 있다. 하지만 아직 웹 애플리케이션 스토어라는 표준이 없고 존재하는 웹 애플리케이션 스토어가 없다. 이를 위해 본 논문에서는 연동에 관한 프로토콜을 제안하고 구현을 통해 기존의 애플리케이션 스토어의 단점을 보완할 수 있는 방법을 제시한다.

Differential die-away analysis (DDAA) technology is a special nuclear material (SNM) active detection analysis technology. Be a nuclear material shielded or not, the technology can reveal the existence of nuclear materials by inducing fission from an external pulsed neutron source. In this paper, a detection model based on DDAA analysis technology was established by geant4 Monte Carlo simulation software, and the optimal sensitivity of the detection system is achieved by optimizing different configurations. After the geant4 simulation and optimization, a prototype was established, and experimental research was carried out. The result shows that the prototype can detect 200 g of ²³⁵U in a steel cylinder shield that's of 1.5 cm in inner diameter, 10 cm in thickness and 280 kg in weight.
