조승호,Cho, Seung-Ho The Society of Digital Policy and Management 2011 디지털융복합연구 Vol.9 No.2

본 연구는 온라인 공동체에서 구성원들 간에 신뢰가 어떻게 형성 발전되는지를 살펴보기 위한 연구이다. 신뢰형성에 주요한 요인에 대한 이론적 고찰을 통해 본 연구는 사회적정체성과 지속적인 커뮤니케이션 활동을 주요한 요인으로 설정하고 이들과 신뢰(Trust)에 이르기 위한 매개변인들인 신뢰성 (Trustworthiness) 요소-Integrity (규범공유성), 선의(Benevolence), 개방성(Openness)-와의 관계를 살펴보았다. 이들 관계를 실증적으로 밝히기 위해서 본 연구는 국내 주요 온라인 사이트의 커뮤니티 구성원을 대상으로 설문을 실시하였다. 그 결과, 사회적정체성과 지속적인 커뮤니케이션이 신뢰성 (Trustworthiness)에 유의미한 영향을 주고 있었으며 신뢰성의 세 가지 변인(Integrity, Benevolence, Openness) 등은 기존의 연구와 유사하게 신뢰에 주요한 요소들임이 밝혀졌다. The current study investigated how interpersonal trust is developed in online communities, where most of individual identities are unknown or doubtful. To better understand and theorize the underlying mechanism, a survey was conducted integrating the literature on computer-mediated communication (CMC) and extending previous research on social identify model. The findings confirmed that integrity, benevolence, and openness are essential components in the concept of trustworthiness, which is predicted by social identification and persistency of communication activities in the virtual community.

Clipping 기반의 무선 인터넷 사이트 구축용 변환 서버 구현

조승호,차정훈,Cho, Seung-Ho,Cha, Jeong-Hoon 한국정보처리학회 2004 정보처리학회논문지 A Vol.11 No.2

현재 유선 인터넷 컨텐츠와 비교할 때 무선 인터넷 컨텐츠가 크게 부족하여 유선 컨텐츠들을 무선 인터넷 컨텐츠로 변환시키고자 하는 요구가 높다. 본 연구의 변환 서버는 사용자 단말기로부터 요청을 자동적으로 인식하여 대상 URL 서버상의 원본 문서를 검색하여 이들을 중간 언어인 metaXML 문서로 생성하고 이를 사용자 단말기에 적합한 무선 마크업 언어 문서로 변환 출판한다. 또한, 본 변환 서버는 이미지 변환을 위하여 이미지 변환기와 기존 웹 페이지들의 재구성 저작 도구인 Clipper와 연동하여 동작한다. 대상 URL의 정적/동적 웹 페이지를 처리하는 변환 서버의 처리 능력에 대하여 성능 실험을 수행하였으며, 동적 문서에 대한 변환 실험 결과에 따르면, 변환 서버내 스레드 풀의 스레드 개수를 5개로 유지할 때 변환 서버가 가장 나은 처리량을 나타내었다. Because a quantity wireless internet contents is much less than wired internet contents, it exist high necessities that wired internet contents should be converted into wireless internet contents. The conversion server implemented in this paper, automatically recognizes the type of user agents when they request, retrieves source documents on the web site specified by an URL, generates metaXML documents as an intermediate form, and converts them wireless markup documents appropriate for user agents. The conversion server interoperates with the image converter for image conversion and the clipper which is an authoring tool for clipping existing wired internet documents. We performed experiments about capability of the conversion server transcoding static/dynamic web pages specified by an URL. According to performance results on dynamic web pages, the conversion server showed better throughput when a thread pool in the terror maintains 5 threads compared with 1 and 10 threads.

스케쥴링 정보를 이용한 동적 부하 균형 기법

조승호(Seung Ho Cho),한상영(Sang Yong Han) 한국정보과학회 1993 정보과학회논문지 Vol.20 No.4

부하를 큐 길이(queue length)로서 표현하는 기존의 부하 표현법은 프로세스들의 수행 특성을 반영하지 못하는 단점이 있으므로, 본 논문에서는 스케쥴링 과정에서 생성된 정보를 이용하여 프로세스들의 수행 특성에 따라 차등화된 가중치를 부여하는 가중치 부하 표현법을 제시한다. 그리고 노드 부하량의 상한값 및 하한값을 유도하기 위하여 유한 모집단(finite population) 대기 행렬 모델을 적용하였으며, 제시된 부하 표현법과 유도된 상한값 및 하한값을 이용하여 동적 부하 균형 알고리즘을 설계하였다. 시뮬레이션 결과들은 제시된 가중치 부하 표현법과 유도된 값들이 부하 균형에 유용함을 보여준다. As the extant load representation method representing, a load as a queue length has a weakness that it does not reflect an execution characteristic of processes, we propose the weight load representation method which assigns graded weights to processes based on the execution characteristic of processes using information generated during process scheduling. We apply the finite population queuing model in order to derive the upper bound value and the lower bound value of a load amount of a node, and design the dynamic load balancing algorithm using a proposed method and derived upper and lower bound values. The simulation results show that the proposed method and values are useful to load balancing.

Neurilemmomas are uncommon benign tumors originating from the schwann cells of various cranial nerves, spinal nerves, and autonomic nerves. About 25% of the disease is found in the head and neck region and the most common single site of origin is known to be the acoustic nerve. However neurilemmomas of the peripheral segment of the lingual nerve are extremely rare neoplasms. We recendy experienced a case of a benign neurilemmoma of the lingual nerve and this case may be the second to be reported in the literature.

Background: Lateral rhinotomy and medial maxillectomy, an en bloc resection of the medial maxillary sinus, ethmoid sinus with the lamina papyracea, medial orbital floor, and lacrimal fossa-duct, have been advocated for lateral nasal wall neoplasms as a standard approach method. Objective: This report was conducted to investigate the clinical efficacy of lateral rhinotomy and medial maxillectomy for lateral nasal wall neoplasms. Materials and Methods: We retrospectively analyzed clinical data of 31 patients who were treated at department of otolaryngology-head and neck surgery, Catholic university of Korea, school of medicine between 1990 and 1996. Results: Twenty five patients had benign lesions(80.6%). By far, the largest percentage was inverted papillomas(80%, 20/25). Of the six malignant lesions(19.4%), 33.3%(2/6) was squamous cell carcinoma and other lesions were metastatic renal cell carcinoma, adecarcinoma, transitional cell cacinoma, and hemangiopericytoma. There were a 4% recurrence for benign tumors(1/25), 5% especially for inverted papilloma(1/20), and 50% for malignant neoplasms(3/6). The overall complication rate was 9.7%. Conclusion: Despite the various approach for treatment of lateral nasal wall neoplasms including inverted papilloma, we continue to advocate a lateral rhinotomy and medial maxillectomy as the treatment of choice.

The purpose of this study was to make search for alternative play of creative problem-solving in technology education. This study is carried out by literature survey. The major findings of this study are as follows : 1. Problem-solving should emphasize the study of `How to Solve` on the database and tool of analysis in after this, as it has attached to the study of `What to Solve` up to recently. 2. Creative problem-solving ability could be summarized the ability and strategy that could logically reorganize ill-structured problem, and it involved the knowledge and ability that were generalizing problem, selection of useful operation and solving procedure. 3. The major factors in the extension of creative problem-solving was promised shortage of knowledge, psychology inertia and inborn character for all people. Therefore, technology educator should consider database and analysis tool as TRIZ/TIPS has. 4. Student learns the concepts of technology knowledge and research method as invention in technology education. For these, the considerations of technology education are as follows : 1) Teach the principle knowledge of technology for the extension of database. 2) Make efficient use of invention for the extension of student`s research competency. 3) Remeber that technology literacy means knowledges and abilities of specialist level. 4) Need to the concept of system in technology education. 5. TRIZ/TIPS that has technological database and analysis tool may be estimated a good alternative plan for extension of creative ability in technology education. But we must develop a textbook and strategy for students.
