오늘날 스마트 폰의 보급이 보편화 되면서 모바일 시장이 크게 성장하게 되었다. 또한 그만큼 많은 사용자들이 이용함에 따라 더 많은 양의 콘텐츠를 제공을 해야 하기 때문에 데이터는 점점 증가 할 수밖에 없는 상황이다. 하지만 잘못된 데이터 정보를 마케팅 같은 곳에 활용하여 피해를 보기 때문에 잘못된 데이터와 신뢰성 데이터를 구분을 하여 신뢰성 있는 데이터를 사용자에게 제공해야 한다. 따라서 본 논문에서는 이러한 문제점을 해결하고자 빅데이터에서 추출하는 과정에서 데이터 품질관리를 실시하고 저장된 데이터도 품질관리를 함으로써 신뢰성 있는 데이터를 생성 및 관리 할 수 있도록 하는 빅데이터 환경에서 최적화된 데이터 품질관리 시스템을 설계한다.

Background: Infantile colic (IC) is excessive crying in otherwise healthy children. Despite vast research efforts, its etiology remains unknown. Purpose: Most treatments for IC carry various side effects. The collection of evidence may inform researchers of new strategies for the management and treatment of IC as well as new clues for understanding its pathogenesis. This review and meta-analysis aimed to evaluate the efficacy and possible mechanisms of probiotics for mananaging IC. Methods: Ten papers met the study inclusion and exclusion criteria, and the meta-analysis was conducted using Review Manager (RevMan) software and a random-effects model. Results: This meta-analysis revealed that probiotics are effective for treating infantile colic, while the review showed that this efficacy may be due to their anti-inflammatory effects. Conclusion: Probiotics may be an important treatment option for managing infantile colic due to their anti-inflammatory properties.

유비쿼터스 시대 다가오면서 임베디드 소프트웨어가 다양한 분야에서의 개발이 증대되며 요구사항도 변화되고 있다. 최근에 다양한 컨버전스 서비스를 지원할 수 있는 컴포넌트 구조 기반의 서비스 지향 모바일 미들웨어 플랫폼 기술 개발이 확산되는 추세이다. 기존의 개발방법들은 하드웨어와의 밀접한 관계, 여러 유사 도메인에 대한 고수준의 재사용성 요구 등 임베디드 소프트웨어가 갖고 있는 특성들을 효과적이로 반영하지 못하고 있다. 본 연구에서는 컴포넌트 기반 임베디드 소프트웨어 개발 프로세스를 정립하고 각 단계에서 필요한 최적의 품질관리 체계를 구축함으로써 경쟁력 있는 임베디드 소프트웨어 제품의 개발을 지원할 수 있는 방법론을 확립하였다.

The development and accomplishment of Open Source Software(OSS) is one of the hottest, as well as the most recent topics in the software industry. Prior studies with respects to OSS have concentrated on discovering both developers and users' rationales of participating OSS projects, analyzing specific OSS solutions or OSS movement itself. However, the empirical study on identifying determinants that influence organizational adoption of OSS and further diffusion of the technology has been a scant. Thus, the main purpose of this study is to investigate the key determinants affecting organizational adoption of OSS. The proposed research model incorporates organizational needs(Evolutional Leadership, Adaptive performance, Readiness for Change) and technological needs(Job Relevance, Cost Benefits, Software Quality) in order to explain organizational OSS adoption. Further, this study assesses the impact organizational OSS adoption has on the OSS Performance and OSS Diffusion. Results from 366 adopting organizations in various industries show three constructs in organizational needs and two constructs in technological needs with exception of Job Relevance have a significant influence on OSS Adoption; and adoption impacts its performance, and diffusion. The implications of the results suggest not only a new theoretical model for OSS research, but also the important implications for OSS diffusion.

This paper has developed the computer integration manufacturing system and Internet based tele-operations. The functions of CIMS include production planing, material requirement planning, work order generation, process control, quality control, shipping planning, warehouse and inventory management and material cost accounting.[1] In this paper focuses on the automatic warehouse control and inventory management by developing the information system as well as the Internet-based integration. The system overview is divided into three parts, the mechanical system, the computer and developed software to control and manage the information and the communication system. The mechanical system consists of the warehouse machine and forklift mobile robot controlled by programmable logic controller (PLC). The computer works on many functions such as control station interfaces with PLC, managing database and inventory, and Internet server to broadcast the inventory database to users via World Wide Web and monitoring the operation on web camera. Our scheme the inventory database can be checked easily anywhere and anytime when the users connect to the Internet. In this article, the lead-time and inventory level can be reduced therefore the holding cost and operating time is also decreased.

System test is an important factor in the development process of good quality complex software in time, ensuring user requirements. Transaction processing module of database management systems schedules multiple transactions effectively and ensures that each transaction preserves data consistency. In this paper, we propose automatic functional testing techniques which ensure systematically that the implemented concurrency control function confirms to its requirements. The proposed testing technique tests functions of concurrency control module based on scenario without user intervention, and displays the result of functional testing. Finally, we utilize the proposed functional testing technique in the testing process of a database management system.

This paper introduces a new multi-product multi-period multi-objective aggregate production planning problem. The proposed problem is modeled using multi-objective mixed-integer mathematical programming. Three objective functions, including minimizing total cost, maximizing customer services level, and maximizing the quality of end-product, are considered, simultaneously. Several constraints such as quantity of production, available time, work force levels, inventory levels, backordering levels, machine capacity, warehouse space and available budget are also considered. Some parameters of the proposed model are assumed to be qualitative and modeled using fuzzy sets. Then, a fuzzy goal programming approach is proposed to solve the model. The proposed approach is applied on a real-world industrial case study of a color and resin production company called Teiph-Saipa. The approach is coded using LINGO software. The efficacy and applicability of the proposed approach are illustrated in the case study. The results of proposed approach are compared with those of the existing experimental methods used in the company. The relative dominance of the proposed approach is revealed in comparison with the experimental method. Finally, a data dictionary, including the way of gathering data for running the model, is proposed in order to facilitate the re-implementation of the model for future development and case studies.

The purpose of the current study is to identify the critical success factors of information systems in small-and-medium-sized firms in general, and also to investigate any differences of those critical success factors between two different industries: the electronic and textile industries. To accomplish this purpose, we collected and analyzed 115 and 108 questionnaires from the electronic and textile industries respectively. From the results of statistical analysis, critical success factors of small-and-medium-sized companies in general were obtained, and critical success factors from two industries were compared and the differences were able to be identified. The results of the analysis of the questionnaires are as follows: 1) The organizational characteristics of the electronic industry showed some differences from those of the textile industry; 2) Small-and-medium-sized companies in the electronic industry appeared to have some differences from companies in the textile industry in terms of critical success factors of information systems. Such factors as education and training, quality level of software, capability of users, business processes, standardization of data management, level of organization, user involvement, support of top management were significantly different between two industries.
