  • This paper presents UI4GSD (User Interface for Grid Service Development) for grid service developers that provides an efficient and friendly development environment based on Globus Toolkit 4, Normally, implementing grid service requires special expert knowledge for Grid as well as programming, Moreover, grid service development as well as testing of the deployed service in the Globus container takes a long Time, which makes the grid service implementation very inefficient, However, UI4GSD can automatically generate a grid service interface file, a build file, and grid service class files as well as a client class file, using the information supplied by developers through GUI. In UI4GSD, a grid service is developed easily based on typical five step processes with required input data fed at each step. As, a result, UI4GSD can provide an easy and convenient development environment thereby increasing the efficiency and convenience in developing grid services.

  • The following conclusions are drawn from Hyungsang medicinal review on th globs hystericus through Donguibogam and other literatures. The globs hystericus appears in the throat and the epigastric region. It is a subjective sensation as if a plum pit is stick in the throat and is compressed, usually ac companied by stuffiness in chest, depression, nausea, and hiccup. But the throat is not marked with redness and swelling. Because Gi stagnation due to seven emotions is the main cause, the globs hystericus is usually followed by Seven Gi injuries, Pain and depressive syndrome due to disorder of Gi, palpitation due to fright, continuous violent palpitation, Gi phlegm, precordial pain with palpitation, epigastric pain due to seven emotions, cough and dyspnea due to disorder of Gi, and six kinds of stagnations. When head and body or chest and abdomen is compared to heaven and earth, the blockage of Gi between heaven and earth is common to the persons with the following charcteristics in Hyungsang; Dam type rather than Bankwang type, Gi type and Shin type rather than deer type and fish type, Taeum and Yangmyeong meridian types out of six meridian types, manly women, womanly man, too long or short neck, and signs of stagnation between the eyebrows. The globus hystericus needs, distinguishing from aphonia, acute tonsilitis, goiter, and pectorial pain with stuffiness. The affected area of aphonia and acute tonsilitis is the throat but they are not cause by the disturbance of seven emotions. Goiter can be distinguished by the changes in the appearance of neck. Even though the symptoms are similar, globus hystericus is caused by the stagnation of Gi, but the pectorial pain with stuffiness, by the insufficiency of the Heart blood. The general prescriptions are Chilgitang, Sachiltang, Gamisachiltang, Gamiijintang, and Sinihwan.

  • Nowadays as many Grid communities appear, the requirement of singlepoint-to-multipoint data transfer in Grid environment is growing. In a typical LAN or a special purpose network environment, a multicasting technology was used in such a data dissemination transfer case. However, compared with unicasting fouler performance transfer performance the multicating transfer is worse, and the obligation of a special hardware setting makes it difficult to implement in common Grid environment. Therefore, in this paper we propose on effective data dissemination mechanism for Grid environment named DDMG(Data Dissemination Mechanism for Grid), DDMG uses P2P(Peer-to-Peer) mechanism and Globus XIO library to improve the performance in a data dissemination process and to support heterogeneous protocols in Grid environment. We also evaluate the performance of DDMG mechanism in LAN and WAN environment by comparing with unicast transfer.

  • Application Contents of based on a workflow process unit in grid system is a practical work to solve the problem. To construct cooperation environment is very important because the contents are deployed and executed. And the most of cooperation is executed by workflow. Globus toolkit is the middleware for cooperation process in grid environment. However the middleware only provides basic services for constructing grid, not workflow that can provides cooperation, job scheduling, application contents management. Also Globus toolkit is suitable for huge gird community but small size pc based grid community. Therefore, this paper proposes the efficient application contents deployment system for small sizes cooperation. This system supports efficient cooperation environment with Application contents deployment and resource management provided in grid community. Also it presents information and association relation among application contents with association dictionary among application contents based on workflow process unit, and utilizes this as information for application contents deployment.

  • Objectives: This study aimed to investigate the clinical characteristics of patients with gastroesophageal reflux disease (GERD) according to globus sensation (GS). Methods: We reviewed the clinical records of 29 GERD patients who visited the Department of Digestive Diseases of Kyung Hee University Korean Medicine Hospital from March 1, 2018 to February 28, 2019. The subjects were classified according to the presence of globus sensation, and the two groups were compared in terms of heart rate variability (HRV) and the Ryodoraku results. Results: In comparing the GERD with GS group (GS group) and the GERD without GS group (non-GS group), a significant difference was found in the duration of symptom and several HRV parameters. The duration of the symptom in the GS group was significantly longer than that in the non-GS group. The non-GS group showed a significantly higher value of total power and high frequency than the GS group. Conclusions: The results suggest a significant difference in the stress level between patients with GERD with GS and those without GS. When approaching patients with GERD without GS, their stress status should be considered.

  • 지리적으로 분산되어 있는 이기종의 분산 컴퓨팅 자원과 대규모 데이터를 효과적으로 활용하기 위해서 최근에 GRID 컴퓨팅 환경에 대한 연구가 매우 활성화되고 있다. 이러한 GRID 환경을 구현하기 위해 필요한 부분중의 하나가 사용자와 자원간의 인증에 관련된 문제이다. 현재 Globus Toolkit은 PKI(Public Key Infrastructure)를 기본으로 하는 보안정책을 사용하고 있다. 이 정책은 인증과정에 적지않은 오버헤드가 발생되는 문제점을 가지고 있다. 이에 본 논문에서는 사용자와 자원간의 직접적인 인증으로 인해 발생하는 성능상의 비효율성을 줄이기 위해 사용자가 자원에 접속 하기전 AIS서버(Authentification Information Server)를 이용하여 미리 인증을 거친후, 자원에 접근한 때는 기 발급된 식별자로 인증 될 수 있도록 처리해주는 메커니즘을 제안한다.

  • 현재 그리드 컴퓨팅 툴킷으로 많이 사용되고 있는 Globus (www.globus.org)는 PKI (Public Key Infrastructure) 기반의 인증방식을 이용하고 있다. 그리드 컴퓨팅은 많은 컴퓨터, 프로그램, 그리고 사람이 동시에 참여하는 컴퓨팅 기술이다. 따라서 컴퓨터와 사용자에 대한 인증서와 키를 체계적이고 사용자 측면에서 효율적으로 관리할 수 있는 방안이 요구된다. 본 연구에서는 사용자들이 자체적으로 인증 기관을 운영하는데 있어 편리하게 인증서를 관리할 수 있는 도구를 개발하였다. 본 연구에서 개발된 웹기반 인증서 관리도구를 이용하여, Globus를 사용하기를 원하는 기관에서는 보다 체계적이고, 자동화된 방법으로 인증서와 키를 관리할 수 있게 된다.
