As the Restaurant industry is growing rapidly. The demand for an effortless POS (Point Of Sale) system which can make management easy is increasing. So, the purpose of this study is to digitalise the growing industry of restaurants and its consumers by utilizing cross-platform development. Crossplatform development frameworks provide great opportunities to solve the issues of handling ubiquitous devices with minimum efforts to reduce the cost and increase the stability, accessibility of the end consumers. By availing those opportunities, an Integrated POS system with cross platform is proposed. This integrated cross-platform POS system is originally designed for a single restaurant managed by its own private cloud server. This research solves the 2 major problems. One of them is the accessibility of the system on modern devices without even writing platform-specific code with the help of cross-platform development. This included web, mobile, desktops & tablets at the same time with the same codebase. Second one is handling data consistency with ubiquitous devices with the help of cloud infrastructure to make data safe and consistent more than ever. In the Development of this system Dart will be used as the primary programming language for cross-platform development. On the Cloud server system apache will be used as the web server and PHP as server side language. System will be using MySQL as the database server.

Purpose: The purpose of this study was to identify the effects of self-efficacy and empowerment on perceived organizational support and organizational citizenship behavior of nurses. Method: The subjects of this study were 327 nurses who were working at seven hospitals. The data were collected by structured questionnaire from Feb. 12 to Mar. 5 of 2006. Data were analyzed using descriptive statistics, t-test, ANOVA, Pearson correlation coefficient, and Stepwise multiple regression on SPSS/PC 12.0 program. Results: The mean score of self-efficacy was 3.75, empowerment was 3.68, perceived organizational support(POS) was 2.87, and organizational citizenship behavior(OCB) was 3.64. The POS had statistically significant differences according to position(F=3.207, p=.013). The self-efficacy and empowerment were positively correlated with POS and OCB. The self-efficacy(7.0%), meaning(8.5%), competency(12.4%), self-determination(1.9%), and impact(4.8%) explained 34.6% of the variance for POS. The self-efficacy(17.1%), meaning(1.0%), competency(2.8%), self-determination(3.2%), and impact(13.2%) explained 37.3% of the variance for OCB. Conclusion: The findings showed that self-efficacy and empowerment were important factors for enhancing POS and OCB in nursing organization. Therefore, the nurse manager must establish the strategies to improve the self-efficacy and empowerment of the nurses in order to promote the POS and OCB.

Wearable computers consisting of various small devices such as smart phones, digital cameras, MP3 players and specialized I/O devices in personal area networks will play an important role in future ubiquitous computing. In this environment, accessing user data is quite complex due to the dynamic and heterogeneous characteristics of the underlying networks. Moreover, since the amount of user data increases rapidly, automatic data backup management is also critical. To overcome these challenges, several studies have been conducted including our previously proposed file service system, PosCFS, which could be adapted to the requirements with a virtualization technique allowing per-user global namespace for managing and accessing data stored on physical storage spaces detected in PAN. In this paper, we present a smart file service framework, PosCFS+ which is an improved and extended version of our previous work. Performance improvement is made possible by redesigning the metadata management scheme based on database and keywords rather than ontology. In addition, the automatic data replication management is newly designed based on the OSD protocol.

Named entity recognition (NER) is an important technique for improving the performance of data mining and big data analytics. In previous studies, NER systems have been employed to identify named-entities using statistical methods based on prior information or linguistic features; however, such methods are limited in that they are unable to recognize unregistered or unlearned objects. In this paper, a method is proposed to extract objects, such as technologies, theories, or person names, by analyzing the collocation relationship between certain words that simultaneously appear around specific words in the abstracts of academic journals. The method is executed as follows. First, the data is preprocessed using data cleaning and sentence detection to separate the text into single sentences. Then, part-of-speech (POS) tagging is applied to the individual sentences. After this, the appearance and collocation information of the other POS tags is analyzed, excluding the entity candidates, such as nouns. Finally, an entity recognition model is created based on analyzing and classifying the information in the sentences.

최대 엔트로피 모델은 자연언어를 모델링하기 위한 좋은 방법이다. 하지만, 최대 엔트로피 모델을 전치사구 접속과 같은 실제 언어 문제에 적용할 때, 자질 선택과 계산 복잡도의 두 가지 문제가 발생한다. 본 논문에서는, 이런 문제와 자연언어 자원에 존재하는 불균형 데이터 문제를 해결하기 위한 최대 엔트로피 부스팅 모델(maximum entropy boosting model)을 제시하고, 이를 영어의 전치사구 접속과 품사 결정 모호성 해소에 적용한다. Wall Street Journal 말뭉치에 대한 실험 결과, 문제의 모델링에 아주 작은 노력을 들였음에도 불구하고, 전치사구 접속 문제에 대해 84.3%의 정확도와 품사 결정 문제에 대해 96.78%의 정확도를 보여 지금까지 알려진 최고의 성능과 비슷한 결과를 보였다.

최근외식프랜차이즈 가맹본사수는증가하고 있지만 가맹본사가 성공보다는실패하는 경우가훨씬 많은 것으로 알려져있다. 여러 실패요인들중에하나는가맹본사의 투명하지못한 경영으로인해, 가맹본사와가맹점간의불신이 있다. 대형외식프랜차이즈경우에는이를 해소하기위해서는ERP와같은통합적정보시스템을이용하고있으나, 소형외식프랜차이즈 가맹본사인 경우는 금전적 인적 자원의 부족으로 매출, 발주관리 등의 기초적인 정보를 다루는 POS(Point of Sale)가 연계된 정보시스템을 겨우 운영하는 실정이다. 소형외식프랜차이즈들의 성공적인 운영을 위해서 저비용으로 현재 시점의 경영상황을 파악할 수 있는 원가관리시스템을 구축할 수 있는 연구가 필요하다. 본 연구에서는 원가관리가 가능하고, POS시스템 종류에 구애받지 않는 표준화된 데이터참조모델을 제안한다. 이를 통해 서비스의 연계 및 재사용성을 촉진하고 중복개발을 방지할 수 있으며, 가맹본사에서는 가맹점별 원가관리를 분석하여 가맹본사와 가맹점들은 투명한 점포경영 뿐만 아니라 효율적 경영지원이 가능하게 될 것이다.

비밀번호 인증 기술에서 키보드로부터 입력되는 데이터가 노출되는 문제점으로 인하여, 이미지 기반 인증 기술이 등장하였다. 이 기술은 주로 가상 키보드를 출력하고, 특정 위치에 클릭된 마우스 정보를 비밀번호로 활용한다. 마우스 데이터의 안전성 향상을 위하여 임의의 마우스 위치를 생성하는 랜덤 마우스 데이터 생성 기술이 등장하였지만, 해당 기술의 안전성 분석에 대한 연구가 미비한 실정이다. 따라서 본 논문에서는 GetCursorPos() 함수를 활용한 공격 기술과 WM_INPUT 메시지를 활용한 공격 기술을 기반으로 랜덤 마우스 데이터 생성 기술이 적용된 사이트에서의 마우스 데이터 취약점을 분석한다.

빅데이터는 현재 기업 경쟁력의 주요 자산으로 여겨지고 있고 향후에 그 영향력은 더욱 확대될 것으로 전망된다. 그 중요성을 인식한 기업들은 이미 빅데이터를 제품 개발과 마케팅에 적극적으로 활용하고 있으며 정치, 스포츠 등 사회 전반에 걸쳐 적용분야는 점점 늘어나고 있다. 그러나 시스템 구축에 따른 노하우 부족과 고비용은 빅데이터 시스템 도입에 여전히 큰 장애가 되고 있다. 본 논문에서는 중소규모 오프라인 마켓의 POS 판매 데이터를 빅데이터 시스템 중 오픈소스인 하둡(Hadoop) 및 하이브(Hive)를 기반으로 하는 빅데이터 시스템 구현을 목표로 한다. 이러한 융복합을 통해 단순히 손익분석과 재고관리 등에 집중되었던 기존 판매 시스템을 보완하여 고객의 소비패턴과 선호도 조사, 수요에 대한 사전 예측이 가능하도록 하는 경영자의 합리적인 의사결정에 기초자료로 활용할 수 있을 것으로 기대된다.

STEP-NC is the next generation CNC controller taking STEP-based data model as the interface scheme (or language) between CAM and CNC, and carrying out various intelligent functions. At the moment, efforts are being made worldwide to establish international standard for the new interface scheme formalized as ISO14649. As the new language is being established, increasing attention is being paid to the development of the new CNC. Korea STEP-NC is an integrated STEP-NC system taking ISO 14649 as an input, and carrying out various intelligent functions. It is composed of 5 modules: 1) Shop Floor Programming System (PosSFP), 2) Tool Path Generator (PosTPG), 3) Tool Path Viewer (PosTPV), 4) Man Machine Interface (PosMMI), and 5) CNC Kernel (PosCNC). Distinguished from other prototypes (of Europe and USA), the Korea STEP-NC is top-down designed, and bottom-up implemented comprehensively incorporating all the crucial components for realizing the full benefit of STEP-NC paradigm, without using any existing commercial CAD/CAM systems and CNC kernels. The Korea STEP-NC prototype was successfully demonstrated and evaluated in the ISO conventions Together with prototypes of Europe and USA, Korea STEP-NC will be used as a reference system fur the Triangular Conformance Test to be jointly carried out by ISO TC184 SC1, SC4, and IMS Project.
