We discuss development of a simulator for automated manufacturing systems (AMSs) which have sophisticated automated material handling equipments and complicated work flows. The simulator is designed to satisfy the following requirements. A user should be able to easily configure or specify an AMS through a graphical user interface (GUI) and minimal data input. The user should be able to model diverse and complied control logic for automated material handling systems like automated guided vehicle (AGV) systems, robot workcell systems and conveyor systems as well as complicated job flow program. Real time animation is desired. Finally, the simulator should be easily maintained and extended. To satisfy the requirements, we use an object-oriented paradigm for modeling, designing, and programming of the simulator. We use an object-oriented modeling framework to design the modeling elements library, and take the process interaction approach for scheduling processes and events. To model a user-defined diverse control logic, we also develop a script language and its interpreter. We explain design and implementation strategies. We implement the simulator using Visual C++ 4.2 and Open GL on Windows NT and the Windows95. Some modeling examples will be demonstrated.

Objectives: The aim of this study is to establish a base for further research by reviewing studies on electroacupuncture (EA) for stress urinary incontinence (SUI). Methods: Clinical studies concerning the effects of EA for SUI, were obtained from Cochrane Library, PubMed, CNKI, RISS, NDSL, KISS and OASIS. Results: Forty-five studies met the criteria, which included 33 RCTs, 1 pilot RCT, 4 non-randomized Clinical Trials, 6 Case studies and 1 Orthogonal design study with 3638 patients. There was only one article published in Korea. In these study, the most common primary outcome measurement was the pad test. Most of the studies showed the group treated by EA effects compared to the control group. Also, many interventions that combined with EA were found and all complex therapy group had significantly better than control group. 7 studies observed adverse events (AEs), four of which referred to EA related AEs among them. And 4 studies reported no AEs associated with EA. Conclusions: Despite several limitations, various studies to prove limited yet effective EA on SUI provides much significance. Subsequent studies conducted by the complementary systematic review of the studies and well-designed clinical trials using the methodological quality will be needed to more firmly validate the therapeutic effect of EA on SUI.

Objectives: To evaluate the effectiveness and safety of application of Traditional East Asian Herbal Medicine (TEAM) in the treatment of Atrophic Vaginitis (AV). Methods: Randomized Controlled Trials (RCTs) were obtained from PubMed, Cochrane Library, Embase, CNKI, RISS, NDSL, and KISS. The risk of bias was assessed by using Cochrane's risk of bias tool, and RevMan 5.3 software was used. Results: 26 RCTs with 3,162 patients were identified and reviewed. Among them, 21 RCTs observe the effect of integrated traditional Chinese and Western medicine. 23 RCTs reported treatment groups was statistically effective than control groups in the study. Also, the recurrence rate was estimated in 10 RCTs and was lower than control groups. 12 studies observed adverse events (AEs) and severe AEs were not reported. Conclusions: This review suggested that TEAM was safe and effective in the treatment of AV. TEAM may also decrease the recurrence rate. However, this could not be proven conclusively. To ensure evidence-based clinical practice, well-designed trials with larger sample sizes are needed.

Objective: The aim of this study was to examine the impact of ATP-binding cassette subfamily B member 1 (ABCB1) C3435T polymorphism on the treatment response of patients to vitamin K antagonists (VKAs). Methods: In this systematic review and meta-analysis, the PubMed/Medline, Embase, and Cochrane Library databases were searched for eligible articles for the period up to November 2020. Articles that reported treatment response to VKAs according to the ABCB1 C3435T polymorphism were included in this study. Results: A total of 13 and 9 articles were included in the systematic review and meta-analysis, respectively. The weekly maintenance dose of warfarin was significantly lower in patients with the ABCB1 3435CT or TT polymorphism type than in those with the ABCB1 3435CC type (weighted mean difference [WMD], -2.53 mg/week; 95% confidence interval [CI], -3.64 to -1.43, p<0.001). However, the weekly maintenance dose of acenocoumarol was not significantly associated with the ABCB1 C3435T polymorphism (WMD, 1.02; 95% CI, -0.61 to 2.65, p=0.22). Conclusion: The ABCB1 C3435T polymorphism was significantly associated with the weekly maintenance dose of warfarin. Further research is needed to confirm the association between the ABCB1 C3435T polymorphism and the incidence rate of bleeding events.

Objectives: ncluding stroke. The aim of this study was to systematically review the clinical evidence of CT for stroke. Methods: To identify randomized controlled trials (RCTs) reporting the effectiveness and/or safety of CT, seven databases including PubMed, EMBASE, and Cochrane Library were searched for articles published from January 2000 to February 2021 without language restrictions. Meta-analysis was performed using Review Manager 5.4 software and the results were presented as mean difference (MD) or standard mean difference (SMD) for continuous variables and odds ratio (OR) for diverse variables with 95% confidence intervals (CIs). Assessment of the methodological quality of the eligible trials was conducted using the Cochrane Collaboration tool for risk of bias in RCTs. Results: Twenty-two RCTs with 1653 participants were included in the final analysis. CT provided additional benefit in improving upper limb motor function (Fugl-Meyer assessment for upper limb motor function, MD 6.91, 95% CI 4.64 to 1.67, P<0.00001) and spasticity (response rate, OR 3.28, 95% CI 1.31 to 8.22, P=0.08) in stroke survivors receiving conventional medical treatment. These findings were supported with a moderate level of evidence. CT did not significantly increase the occurrence of adverse events. Conclusions: This study demonstrated the potential of CT to be beneficial in managing a variety of complications in stroke survivors. However, to compensate for the shortcomings of the existing evidence, rigorously designed large-scale RCTs are warranted in the future.

A review of randomized controlled trials (RCTs) using electroacupuncture (EA) to treat patients with foot drop was performed to analyze the effectiveness of EA for this condition. Relevant studies (n = 183) from 7 databases (Cochrane Library, Excerpta Medica Database, PubMed, China National Knowledge Infrastructure, Korean Studies Information Service System, Research Information Sharing Service, and Oriental Medicine Advanced Searching Integrated System) were selected based on the inclusion and exclusion criteria, and 12 RCTs met the selection criteria. In all 12 studies, EA showed significantly positive changes. In most indicators, positive changes were observed in the EA group compared with that in the control group. Significant increases were confirmed in muscle strength-related indicators such as the Fugl-Meyer motor scale, surface electromyography, active range of motion, and gait-related indicators such as the Tinetti score, maximum walking speed, and Berg balance scale. No notable adverse events were reported. EA is suggested as an effective treatment for post-stroke foot drop; however, more RCTs are required.

이 연구에서는 FR 모형과 LRM을 개체, 속성, 관계 측면에서 비교 분석하여 목록 관련 표준 및 개별 시스템에서 LRM을 수용할 수 있도록 LRM 특성과 그 적용방안을 모색하고자 한다. LRM 특성에 따른 적용방안으로 다음을 제시하였다. 첫째, LRM에서 가족, 단체, 식별자, 전거형접근점, 개념, 대상, 사건, 기관, 규칙의 개체가 삭제되었지만, LRM을 적용하려는 표준과 시스템에서 필요시 하위 개체를 정의하여 개체를 확장해야 한다. 둘째, 링크드데이터를 위해 LRM에서는 속성 요소가 관계로 변경되면서 속성이 많이 감소하였으나, LRM을 수용하려는 표준과 시스템에서는 속성을 세분하여 확장해야 한다. 특히, LRM에서는 유사한 기능을 갖거나 여러 개체에서 반복되는 속성과 자료에 특화된 속성이 포괄적인 일반화된 속성명으로 통합되었기 때문에 표준 및 개별 시스템에서는 보다 구체적이고 세부적인 속성명을 명확하게 제시해야 하며, 속성에 해당하는 어휘인코딩스킴도 개발되어야 한다. 셋째, 관계가 속성에 비해서는 증가되었으나 관계 자체가 추상적이기 때문에, 관계는 세목화 및 다단계 관계를 통해 관계가 확장되어야 한다. 본 연구는 목록 관련 표준 및 시스템에서 LRM을 적용하는 경우 적용방안 모색에 활용될 수 있을 것이다.

이 연구에서는 기록이 '정체성 강화'에 도움을 줄 수 있다고 보고, 직업 아카이브가 직업에 대한 역사와 문화를 보존함으로써 직업에 대한 자부심과 정체성 확립에 도움을 줄 수 있을 것으로 보았다. 이 연구에서는 특히 도서관 사서를 중심으로 '도서관 사서 아카이브'를 구축함으로써 도서관 사서와 관련된 기록을 보존하고 사서 간 경험과 지식을 공유하고자 하였다. 나아가 이와 같은 아카이브가 본인 스스로와 집단의 역사와 정체성을 확인하는 데 도움을 줄 수 있는지 알아보고, 그 구축 방안을 제시해 보고자 하였다. 사서를 대상으로 심층 면담을 진행하여 도서관 사서 아카이브에는 어떤 기록이 포함되어야 하는지, 어떤 기록이 사서의 정체성 강화에 도움을 줄 수 있는지 등을 살펴보았다. 면담 결과 사서의 업무와 관련된 다양한 기록을 확인하였고, 사서의 역사와 관련된 기록도 확인하였다. 또한 도서관 사서와 관련한 역사적 사건이나 앞세대 사서들이 해왔던 도서관 서비스 등이 사서의 정체성을 강화하는 데 도움을 줄 것으로 나타났다. 즉, 도서관 사서 아카이브는 사서들에게 사서로서의 본인을 돌아보고 자신이 나아갈 방향을 정하는 데 도움을 줄 수 있는 것으로 보인다. 이 연구에서는 기관과 공동체 간의 협력을 통한 참여형 아카이브 구축을 제시하였다. 도서관 및 사서 기록은 한 기관만의 기록을 넘어 다양한 도서관과 공동체들의 기록이 필요하기 때문이다. 이 연구에서는 도서관 사서 아카이브 구축을 통해서 사서의 직업 정체성 강화, 사서의 역사 공유, 집단 지성 플랫폼, 효율적인 업무처리, 도서관과 사서의 사회적 지위 향상 등을 얻을 수 있을 것으로 보았다.
