  • 본문에서는 최근 들어 각광을 받고 있는 패턴인식 방법론인 Support Vector Machine을 이용하여 중국어 개체명을 식별하는 방법을 제안하고자 한다. SVM(support vector machine)은 입력 자질이 많을 경우에도 안정적인 성능을 나타내고 보편적으로 적용할 수 있는 모델을 개발할 수 있는 장점이 있다. 실험에서 어휘. 품사, 의미부류 등 많은 수의 자질을 이용하였다. 실험결과는 본문에서 제안한 방법이 튜닝을 거치지 않아도 좋은 성능을 나타낼 수 있고, 수행 속도도 만족스럽다는 것을 보여주었다.

  • Organizations are investing in information systems for an ever-increasing number of end-user tasks. Extracting benefit from these investments increasingly depends on supporting effective use or information center and satisfying information center users. Information center is information intensive and the use of advanced technology may support user for delivering an unique capabilities in an organization. Information center represents an important source which seems very well suited for end-users support investigation. This research explores the end-user support factors that correlate with user satisfaction in information center. To exam user satisfaction, information supporting, service reliability, and system capabilities were identified as potential predictors of end-user support satisfaction at information center. Three hypotheses have been tested with the survey or 252 end-users examines 18 potential end-user support factors such as information supporting, service staff attitude, and system capabilities at information center. Service quality gap between perceived Importance and performance for each support factor, is computed. The relationship between these service quality gaps and user satisfaction are tested. This study presents that the level of information supporting, service reliability, and system capabilities are significantly to user satisfaction, and it is influenced by the extent of service quality gap between perceived importance and performance for each support tactor.

  • For scalable multicast transport, one of the promising approaches is to employ a control tree known as acknowledgement (ACK) tree which can be used to convey information on reliability and session status from receivers to a root sender. The existing tree configuration has focused on a 'bottom-up' scheme in which ACK trees grow from leaf receivers toward a root sender. This paper proposes an alternative 'top-down' configuration where an ACK tree begins at the root sender and gradually expands by including non-tree nodes into the tree in a stepwise manner. The proposed scheme is simple and practical to implement along with multicast transport protocols. It is also employed as a tree configuration in the Enhanced Communications Transport Protocol, which has been standardized in the ITU-T and ISO/IEC JTC1. From experimental simulations, we see that the top-down scheme provides advantages over the existing bottom-up one in terms of the number of control messages required for tree configuration and the number of tree levels.

  • We have fabricated pentacene OTFT on ultra-thin flexible polyimide film with a rigid glass support. Polyimide film of the thickness of $10{\mu}m$ has formed on glass by spin coating from the solution. After the entire OTFT process, the OTFT exhibited a fieldeffect mobility of $0.4\;cm^2/Vs$, an $I_{on}/I_{off}$ ratio of $10^7$ and a subthreshold swing of 0.7 V/dec. The OTFT on polyimide film has been detached from the glass support and laminated on a plastic support of $130\;{\mu}m-thick$ PET film. After the detach process, in spite of the degrading of its field-effect mobility, the OTFT showed high $I_{on}/I_{off}$ as high $as{\sim}10^6$.

  • This study focused on the Healthy Family Support Center and Multicultural Family Support Center, which supervise the main field of family resource management with institutional household factors. Our research objective was to present datas demonstrating an improvement in the organizational effectiveness of the Multicultural Family Support Center. The burn out average of employees working for the non-profit organization was 2.45, emotional burnout was 2.87, achievement was 2.43, and dehumanization was 2.06. The effectiveness average of the nonprofit organization was 3.56, profitability was 3.65, job satisfaction was 3.58, and organizational commitment was 3.45. The generic characters that caused burnout were age, information, and professionalism in research. The generic characters and burnout that affected the organizational effectiveness included a lack of accomplishment, and emotional exhaustion, and depersonalization, lack of information and professionalism, lack of external resources in that order. The purpose of this research was to determine the effects of burnout in order to prevent job changes and to provide basic data for the improvement of organizational effectiveness.

  • SME's (Small and Medium-sized Enterprises) have limited resources to build information systems on their own. We suggest what government need to do to support SME's, which includes establishing a one-stop service center, outsourcing of public service, and triggering strategy In order for the government support to be effective, it should serve SME's needs continuously and professionally.

  • The National Emergency Management Agency of South Korea has established a Disaster Victims Psychology Support Center. The Disaster Victims Psychology Support Center can enable victims who got psychological damage from disasters to return to their daily lives through healing activity, field visits and advice of experts. The previous Psychology Support Center System managed the information of disaster victims through an independent database. However, this paper proposes a system that is developed to identify medical institutions and mental health centers within a distance of radius, based on the potential Hot-Spot areas of disaster victims using the GIS Systems. The proposed system can efficiently support selection of appropriate institutions for disaster victims using their location and age, classification of damage, and damaged parts of the body. Also, this spatial analysis can assist to decide on a policy based on the location of disaster victims and the extent of damage. Therefore, this paper can provide the required information to support decision making based on the concentrated areas for disaster victims.

  • Objective: Improvements in diet can decrease the cancer rates. The aim of the present study was to determine the relationships between self-perception of diet quality and personality, impulsiveness, stress, coping strategy, sense of coherence, self-efficacy, and social support. Methods: This cross-sectional study was conducted using a multiple-stratified random sampling method based on the Korea Census of 2007. In October 2009, investigators conducted 15-minute face-to-face interviews with 1,530 South Korean volunteers who ranged from 30 to 69 years of age without a history of cancer. Results: Respondents were more likely to perceive that they consumed a healthy diet if they were older than 50 years, lived with a partner, had a monthly family income greater than $4,000 USD, had a low perceived risk of cancer, consumed less alcohol, exercised regularly, had a less agreeable or conscientious personality, had low stress levels, had a high sense of coherence or self-efficacy, and had ample social support. Conclusion: Psychosocial factors, such as personality, stress, sense of coherence, self-efficacy, and social support, are associated with the self-perception of diet quality. Analysis of the factors that contribute to a perceived healthy diet could assist with the design of educational campaigns.
