  • GIS (Geographic Information Systems) technology is a necessary function to support location based on service by using GPS in the mobile environment. These mobile systems have basic functional limitations such as a low rate of processing, limited memory capacity, and small screen size. Because of these limitations, most of the mobile systems require development of a reduced digital map to overcome problems with large-volume spatial data. In this paper, we suggest using the reduced digital map format in order to use location based on service in a PDA environment. The processing of the proposed data format consists of map generation, redefinition of layers, creating polygons, and format conversion. The proposed data format reduces the data size by about 98% comparing with DXF format based on the digital map of Busan.

  • 본 연구는 다양한 기능영역 간의 연계성을 확보하고, 창의적 사고와 혁신을 유인하기 위해 운영되는 다기능프로젝트팀(Cross-Functional Project Team)의 성과 창출에 관하여 연구하였다. 기존 소집단 유효성 연구는 팀 프로세스가 중요함을, 조직맥락 연구에서는 팀 구조설계 및 긍정적인 조직맥락 조성을 강조하고 있는 바에 기초하여 다기능프로젝트팀만의 차별적 특성을 반영한 성과 영향 요인을 도출하고 영향력을 검증하였다. 또한 리더 행위로서의 팀 코칭(team coaching)이 갖는 조절효과도 파악하였다. 17개 서울 및 수도권 소재 기업에서 운영한 다기능프로젝트팀 32개, 214명을 대상으로 자료를 확보하여 분석한 결과, 역량구성 적절성과 팀 보상시스템이 팀 프로세스 및 팀 성과에 유의한 영향력을 가진다는 결과를 도출하였다. 또한 팀 코칭이 팀 프로세스 및 팀 성과에 갖는 직접적 영향관계를 파악하였다. 이러한 연구결과에 대한 이론적.경영관리적 시사점 및 향후 연구방향에 대해 논의하였다.

  • Aptamers are functional nucleic acids that can specially bind to proteins, peptides, amino acids. nucleotides, drugs, vitamins and other organic and inorganic compounds. The aptamers are identified from random DNA or RNA libraries by a SELEX (systematic evolution of ligands by exponential amplification) process. As aptamers have the advantage, and potential ability to be released from the limitations of antibodies, they are attractive to a wide range of therapeutic and diagnostic applications. Aptamers, with a high-affinity and specificity, could fulfil molecular the recognition needs of various fields in biotechnology. In this work, we reviewed some aptamer Selection techniques, properties, medical applications of their molecules and their biotechnological applications, such as ELONA (enzyme linked oligonucleotide assay), flow cytometry, biosensors, electrophoresis, chromatography and microarrays.

  • It is well known that patients with severe facial injuries accompanied by facial disfiguration are vulnerable to a poor quality of life. With the help of facial transplantation, it has become possible to achieve an optimal anatomical reconstruction. As compared to conventional methods, it can provide more desirable functional, aesthetic, and psychosocial outcomes. Face transplantation surgeons need to consider many problems associated with the criteria for selecting patients, techniques for harvesting the donor tissue, prediction of the expected functional outcomes, limitations in obtaining written informed consent for conducting the procedure, evaluation of the post-transplant immunological response and postoperative immunosuppressant requirements, psychological and social outcomes for the patients, and other concerns about funding and ethical issues.

  • Prosthodontic treatment planning for various edentulous arches is not an easy issue for dentists. Especially, in case of removable partial denture, we must have a knowledge of overall treatment procedures, and a careful approach is needed. Recently, interest of dental implant and case reports are increasing, the decrease of the removable partial denture is true, but dental implantation takes longer treatment period and it is more expensive. Also, there are still some limitations like lack of available alveolar bone, patient's general condition, and chronic periodontitis. Therefore, sometimes implantation is impossible. Finally, implantation cannot be adapted to every single patient. Currently, the clasp type removable partial dentures are used routinely, giving patients many unesthetic and functional difficulties. With better laboratory technique, removable partial denture with attachment and removable partial denture in rigid type increase patient's happiness level much more than predicted. The case presented in this article, clinically demonstrate the efficiency of using a telescopic system to improve esthetic and functional recovery for patients who lose multiple teeth.

  • Objectives:Functional magnetic resonance imaging(fMRI) is one of the most useful techniques for assessing localized changes in cerebral blood flow and oxygenation using diverse challenge paradigms. This review presents the results of fMRI studies relating to schizophrenia. Methods:Several fMRI articles on this subject in psychiatric journals were surveyed. Results:Even with some methodological limitations, most studies showed activity differences between schizophrenics and control subjects. Conclusion:fMRI extends our understanding of the pathophysiological basis of schizophrenia and offer an opportunity for the assessment and management of its pathology.

  • Advance of neuroimaging technique has greatly influenced recent brain research field. Among various neuroimaging modalities, positron emission tomography has played a key role in molecular neuroimaging though functional MRI has taken over its role in the cognitive neuroscience. As the analysis technique for PET data is more sophisticated, the complexity of the method is more increasing. Despite the wide usage of the neuroimaging techniques, the assumption and limitation of procedures have not often been dealt with for the clinician and researchers, which might be critical for reliability and interpretation of the results. In the current paper, steps of voxel-based statistical analysis of PET including preprocessing, intensity normalization, spatial normalization, and partial volume correction will be revisited in terms of the principles and limitations. Additionally, new image analysis techniques such as surface-based PET analysis, correlational analysis and multimodal imaging by combining PET and DTI, PET and TMS or EEG will also be discussed.

  • 웹 서비스의 검색방법은 기능적인 측면만 고려하여 사용자가 원하는 서비스 검색에 대한 한계가 있다. 본 연구에서는 기능적인 면을 고려한 웹 서비스에서의 문제점을 개선시키기 위해 웹 서비스의 WSDL과 매칭정보를 이용하여 기능적인 부분과 비 기능적인 면을 고려한 서비스 선정 방법을 제시한다. 본 연구에서는 웹 서비스 클라이언트들이 서비스 선정 시 클라이언트가 정의한 매칭정보를 만족하는 클라이언트 측면을 고려한 최적의 서비스 선정을 할 수 있도록 서비스 선정 방법에 대한 아키텍처와 선정 프로세스를 연구하고 웹 서비스 선정 프로세스에서 제공되는 기능적인 요구의 매칭뿐만 아니라 클라이언트 요구도 수용할 수 있는 매칭정보를 고려한 최적의 서비스 선정 방법을 연구한다. 본 연구에서는 제안한 매칭정보 추출 및 선정프로세스를 이용하여 사용자 중심의 비 기능적인 측면을 고려한 웹 서비스를 이용할 수 있어 사용자가 원하는 품질을 제공하는 서비스를 제공 받을 수 있도록 최적의 서비스를 제공 할 수 있다.

  • Objectives: This study aims to supplement the limitations of the preliminary study and expand the use of the Child-Adolescent Functional Assessment Scale by providing standardized T-scores for measuring function in different areas, as well as guidelines for their interpretation. Methods: The Child-Adolescent Functional Assessment Scale and Korean-Child Behavior Checklist were administered to a total of 623 individuals, including 467 parents of emotionally and behaviorally disturbed elementary school students, 45 parents of emotionally and behaviorally disturbed middle school adolescents and 111 parents of elementary school students with developmental disorders, as well as to a control group consisting of 186 parents of mainstream elementary school children in the Seoul metropolitan area. Results: In contrast to the preliminary study, the emotional domain was disassociated into two factors, negative affect and emotion regulation, and the coefficient of determination for misconduct was increased significantly. Also, the overall reliability and validity of the Child-Adolescent Functional Assessment Scale were similar to those in the preliminary study, and the item structure was consistent. This study provides standardized T-scores of function in different areas based on the revised scale, and provides guidelines for their interpretation. Conclusion: The Child-Adolescent Functional Assessment Scale can assist the Child Global Assessment in Functioning in providing the information necessary for case management and treatment planning by comparing the impairment severity in each area of functioning, and also determining changes in behavior and function after treatment interventions. On the other hand, this scale has yet to clearly distinguish between rebellious behavior and misconduct. Further research is necessary to provide standards for more diverse age groups and for its utilization.
