워크플로우는 컴퓨터에 의해서 자동으로 실행되고 관리되는 업무 프로세스이다. 워크플로우 기술은 기업 환경의 변화와 함께, 비즈니스 프로세스 관리(BPM:Business Process Management)의 개념과 함께 발전해 왔다. 또한비즈니스를 수행하기 원하는 기업의 거래파트너간, 고객, 공급자들의 분리된 비즈니스 환경을 제거하고, 향상된 e-비즈니스를 수행하기 위한 통합 환경을 제공해주는 웹 서비스는 워크플로우를 구성하는 매우 중요한 개념이 되었고, 이러한 웹 서비스의 흐름을 정의하는 워크플로우 설계 언어가 많이 등장하였다. 그 중 가장 표준이 될 가능성이 유력한 BPEL4WS는 비즈니스 프로세스에 필요한 트랜잭션, 보상 등의 개념을 포함하여, 효율적으로 비즈니스 프로스세스를 구성할 수 있게 해 준다. 그러나 BPEL4WS는 1)고정된 WSDL파일을 참조하여, 그 흐름을 정적으로만 구성할 수 있다는 단점이 있고, 2)제한된 자원만을 갖고 있기 때문에, 의미를 부여할 수 없어 대체 서비스를 찾을 수 없다는 단점이 있다. 따라서 본 논문에서는 이러한 단점을 해결하기 위하여 기존의 WSDL에 의미(Semantic)을 부여하는 방법으로 이를 해결하고자 한다.

Dental injections are routinely performed and can result in pain and anxiety in patients. This systematic review aimed to evaluate the efficacy of photobiomodulation therapy (PBMT) in dental injections for pain management in patients undergoing dental treatment. Indexed databases, including PubMed, EMBASE, Scopus, ISI Web of Knowledge, and Cochrane Library, were electronically searched without a time limit up to February 2024. A risk of bias evaluation was performed using the Cochrane tool. A preliminary investigation using electronic and manual methods yielded 4,920,881 manuscripts. Based on the eligibility requirements, 13 randomized control trials (RCTs) were included. Self-assessed pain was determined using the visual analog scale, Face, Legs, Activity, Cry, Controllability scale, or Wong-Baker face pain scale. Eight RCTs demonstrated a notable decrease in needle pain in patients undergoing dental needle injections using PBMT. Based on current evidence, PBMT may help reduce needle pain related to dental anesthesia. Further standardized studies are needed to assess the significance of PBMT for postoperative pain in patients undergoing dental injections.

Purpose: This study aimed to report the current trends in the management of diabetic foot over the last few decades through a survey of the Korean Foot and Ankle Society (KFAS) members. Materials and Methods: A web-based questionnaire containing 40 questions was sent to all KFAS members in September 2021. The questions were mainly related to the demographics of patients with diabetic foot, diagnostic tools, and multidisciplinary treatment. Answers with a prevalence of ≥50% of respondents were considered a tendency. Results: Seventy-eight of the 550 members (14.2%) responded to the survey. The most common demographic factors of diabetic foot patients were male dominance with a high percentage in the 60- to 70-year-old. Although the need for multidisciplinary treatment is highly recognized in the treatment of diabetic foot patients, the actual implementation rate is about 39%. The contrast-enhanced magnetic resonance imaging (88.5%) was reported to be the most used tool for the diagnosis of osteomyelitis of the diabetic foot. It was reported that the use of antibiotics was started empirically and then changed based on bacterial culture tests in 82.1% of patients. Simple wound dressing and antibiotic treatment were most frequently reported for mild ulcers. Conclusion: This study provides updated information on the current trends in the management of a diabetic foot in Korea. Both consensus and variations in the approach to patients with diabetic foot were identified by this survey study. Further efforts are required for better access to a multidisciplinary approach, such as appropriate insurance payment policies and patient education.

To monitor and predict the change of coastal environment according to the construction of Saemangeum sea dyke and the development of land reclamation, we have done real-time and periodic ocean observation and numerical simulation since 2002. Saemangeum coastal environmental data can be largely classified to marine meteorology, ocean physics and circulation, water quality, marine geology and marine ecosystem and each part of data has been generated continuously and accumulated over about 10 years. The collected coastal environmental data are huge amounts of heterogeneous dataset and have some characteristics of multi-dimension, multivariate and spatio-temporal distribution. Thus the implementation of information system possible to data collection, processing, management and service is necessary. In this study, through the implementation of Saemangeum coastal environmental information system using geographic information system, it enables the integral data collection and management and the data querying and analysis of enormous and high-complexity data through the design of intuitive and effective web user interface and scientific data visualization using statistical graphs and thematic cartography. Furthermore, through the quantitative analysis of trend changed over long-term by the geo-spatial analysis with geo- processing, it's being used as a tool for provide a scientific basis for sustainable development and decision support in Saemangeum coast. Moreover, for the effective web-based information service, multi-level map cache, multi-layer architecture and geospatial database were implemented together.

As the usage of information resources produced in various media and forms has been increased, the importance of metadata as a tool of information organization to describe the information resources becomes increasingly crucial. The purposes of this study are to analyze and to demonstrate the intellectual structure in the field of metadata through co-word analysis. The data set was collected from the journals which were registered in the Core collection of Web of Science citation database during the period from January 1, 1998 to July 8, 2016. Among them, the bibliographic data from 727 journals was collected using Topic category search with the query word 'metadata'. From 727 journal articles, 410 journals with author keywords were selected and after data preprocessing, 1,137 author keywords were extracted. Finally, a total of 37 final keywords which had more than 6 frequency were selected for analysis. In order to demonstrate the intellectual structure of metadata field, network analysis was conducted. As a result, 2 domains and 9 clusters were derived, and intellectual relations among keywords from metadata field were visualized, and proposed keywords with high global centrality and local centrality. Six clusters from cluster analysis were shown in the map of multidimensional scaling, and the knowledge structure was proposed based on the correlations among each keywords. The results of this study are expected to help to understand the intellectual structure of metadata field through visualization and to guide directions in new approaches of metadata related studies.
