Traditional document analysis systems used word-based analysis using a morphological analyzer or TF-IDF technique. These systems have the advantage of being able to derive key keywords by calculating the weights of the keywords. On the other hand, it is not appropriate to analyze the contents of documents due to the structural limitations. To solve this problem, the proposed algorithm calculates the weights of the documents in the document and divides the paragraphs into areas. And we calculate the importance of the divided regions and let the user know the area with the most important paragraphs in the document. So, it is expected that the user will be provided with a service suitable for analyzing documents rather than using existing document analysis systems.

AMOLED panels are being used instead of LCD panels. In addition, various process technologies for quality improvement are being studied. These studies require algorithms to perform aging correction and to extract aging correction values. In this paper, we propose a voltage setting algorithm for the aging correction of AMOLED. The voltage setting algorithm calculates and corrects the output voltage by calculating the correction value of the voltage setting. As a result, the required voltage can be supplied according to each channel in the embedded board.

Traditional miniature micro-controllers focus on communication only because of memory capacity is low due to small size. Due to this, it is difficult to mount the UI for user convenience in the control system and a lot of functions cannot be added. To solve this problem, this paper proposes a weight reduction and encoding method for the control system. In addition, it is increased user convenience by overcoming the problem of difficulty in Korean system in the existing system. Also, we can add various functions to the memory space secured by system weight reduction.

The authors investigated demographic characteristics, role, job satisfaction, and necessity of education of the shop masters and sale persons who worked at clothing shops in department stores. Shop masters were older, had worked longer, and received more salary than sales persons. Role difference was not clear, but shop masters worked more in display, suggestion of merchandise change and order, and management of shop. Shop masters had more pride in job than sales persons, and both of them wanted more education about job.

PEDOT[Poly(3,4-Ethylenedioxythiophene)]박막의 제작은 산화촉매제를 이용한 기상중합(Vapor Phase Polymerization)방법을 통해 최근 활발히 연구되어 지고 있다. 기상중합된 PEDOT박막의 특성은 박막의 중합의 정도와 성장 형상에 따라 그 특성이 크게 좌우된다. PEODT박막의 효율적인 중합에 있어 산화촉매제의 균일한 도포는 매우 중요하다. PEDOT의 효율적인 중합과 균일도포를 위해 산화촉매제에 DUDO와 PEG-PPG-PEG를 첨가한 혼합용액을 제작 VPP방법을 통해 PEDOT박막의 제작을 시도하였다. 그 결과 spin-coating 시 산화촉매 혼합용액의 균일한 도포가 관찰 되었으며 산화촉매제만 사용하여 제작된 박막에 비해 전도도와 막질이 향상된 PEDOT박막이 제작되었다. 이러한 결과는 산화촉매용액에 첨가된 PEG-PPG-PEG와 DUDO의 영향으로 PEG-PPG-PEG는 oxdiant용액의 균일 도포를 도왔으며 Inhibitor로 작용하는 DUDO는 PEDOT성장에 있어 불균일 결정성장을 억제하여 조밀한 PEDOT 박막 성장을 도운 것으로 생각된다. PEDOT 박막의 특성평가에는 Field Emission-Scanning Electron Microscopy, 4-Pointprobe, Optical microscopy 등이 사용되었다. 이러한 고전도도의 PEDOT박막을 OTFT의 전극소재로 사용한다면 OTFT소자의 성능 향상에있어 크게 기여 할 것으로 기대된다.

This experiment was conducted to investigate the effect of ethylene adsorbent removing ethylene gas produced from apple fruits in poly ethylene film bag storage. The treatment of ethylene adsorbent was not effected the change in soluble solids and organic acid content of fruits. The fruit softening was remarkably delayed by the absorbent treatment, and the more amount of it was the more effective. The ethylene evolution and respiration of fruits reduced or decreased by this treatment during storage. The ethylene adsorbent for 'Fuji' apple fruit was effective more than 30g per 10kg fruits.

To develop a new functional wine, manufacture and quality characteristics of wild grape wine were investigated. Ethanol contents of wild grape wine was 11.0%, and total acidity and volatile acid content were 0.63% and 0.0402%, respectively. Antioxidant activity of the wild grape wine which is related in anti-aging functionality, was 41.6%. From this results, we concluded that the wild grape wine is a high valuable wine.

Today, as wireless communications devices such as laptops, smart phones are generalized, wireless LAN has been widely installed in the corporate office conference rooms, industrial warehouses, Internet-ready classrooms, and even in a coffee shop. Though a wired network can be accessed and attacked only by the physical penetration, the wireless network which can be accessed anywhere within the reach of anyone has relative vulnerability by unauthorized users' attack. To defend these vulnerabilities, the introduction of WIDS / WIPS is required. In this paper, we recognize the limitations of WLAN security technology, review the current technology trends and propose the solutions in the future security problems.

Before the Machine Socialization System used to connected between server and router. However, the data flow increases due to the poor performance of the router increased traffic, as a result, the loss of data when the problem occurred Collaboration between devices increases that have been interrupted. This action moves the server connected to the router is required to solve these problems. In this paper, by utilizing the cloud server to reduce bottlenecks proposed a system that can reduce the loss of data during cooperation between devices. In addition, by dividing the management unit and the sensor using the virtualization technology, we designed a system that can efficiently make use of the resource.

Existing morpheme analyzers classify the words used in writing documents. A system for extracting sentences and paragraphs based on a morpheme analyzer is being developed. However, there are very few systems that compress documents and extract important paragraphs. The algorithm proposed in this paper calculates the weights of the keyword written in the document and extracts the paragraphs containing the keyword. Users can reduce the time to understand the document by reading the paragraphs containing the keyword without reading the entire document. In addition, since the number of extracted paragraphs differs according to the number of keyword used in the search, the user can search various patterns compared to the existing system.
