The purpose of this study is to incorporate telemarketing processes to improve telemarketing performance. For this application, we have attempted to mix the model of machine learning to extract potential customers with personalisation techniques to derive recommended products from actual contact. Most of traditional recommendation systems were mainly in ways such as collaborative filtering, which predicts items with a high likelihood of future purchase, based on existing purchase transactions or preferences for products. But, under these systems, new users or items added to the system do not have sufficient information, and generally cause problems such as a cold start that can not obtain satisfactory recommendation items. Also, indiscriminate telemarketing attempts can backfire as they increase the dissatisfaction and fatigue of customers who do not want to be contacted. To this purpose, this study presented a multi-purpose hybrid recommendation algorithm to achieve two goals: to select customers with high possibility of contact, and to recommend products to selected customers. In addition, we used subscription data from telemarketing agency that handles insurance products to derive realistic applicability of the proposed recommendation system. Our proposed recommendation system would certainly solve the cold start and scarcity problem of existing recommendation algorithm by using contents information such as customer master information and telemarketing history. Also. the model could show excellent performance not only in terms of overall performance but also in terms of the recommendation success rate of the unpopular product.

IoT, 빅데이터, 드론, 클라우드 등 정보기술이 등장하면서 정보화 사회가 지능화, 창조화사회로 변화되고 있으며, 건설분야에서도 이러한 정보기술을 접목하여 과거의 노동집약형 산업에서 융합형 첨단기술산업으로 변화를 도모하고 있다. 특히, 건설사업관리시스템은 1998년부터 5년마다 건설사업정보화 기본계획을 수립하여 기능개선 및 고도화를 진행하고 있으며, 현재 2012년에 수립한 제4차 건설사업정보화 기본계획을 기반으로 시스템을 개선중에 있다. 그러나, 급변하는 정보기술의 발전으로 웹호환성, 공간정보, 빅데이터, BIM, 윈도우10 등이 대두되면서, 시스템 개편을 위한 체계적인 계획 수립이 필요한 실정이었다. 따라서, 본 연구는 건설사업관리시스템을 기준으로 새로운 건설IT환경을 반영한 시스템 로드맵을 마련하였다. 이를 위해 건설분야의 내 외부 환경요인을 조사 분석하고, 타 정보시스템의 개발현황과 건설사업관리시스템의 문제점을 도출한 후 SWOT 분석기법을 이용하여 핵심성공요인을 도출하였다. 도출된 결과를 토대로 시스템의 비전, 목표, 추진방향 및 전략, 중점 세부추진과제와 추진일정을 마련하고 델파이방법을 통해 최종적으로 4개 중점추진과제와 9개 세부추진 과제를 마련하였다. 이렇게 마련된 로드맵은 향후 건설사업관리시스템의 운영 지표로 활용되며, 건설분야 유관 정보시스템의 향후 추진전략 수립시 참고자료로 활용될 수 있다.

According to the change in diverse tendency of residents, construction companies has developed the brands of apartments with the concepts of LOHAS, well-being, ubiquitous, etc. The purpose of this study was to suggest space requirement and planning for residents characteristics. The questionnaire survey was adopted in this study and 252 cases were used for data analysis. The survey analysis has been made by using of SPSS WIN 12.0. The major findings were as follows; (1) Resident opinion about the direction of each space was investigated into the need of South-facing in master bedroom highly. (2) The residents didn't want to decrease the current size of each space, the space which wanted to increase was livingroom. (3) The significant variables of space requirement and planning for residents characteristics were family life cycle, the age of householder, the occupation of householder, the size of apartment.

This paper proposes a novel scheme of designating non-cacheable addresses of memories in embedded systems of multi-master architectures without a Memory Management Unit (MMU). As a solution for data coherency problem between external memories and a cache memory, we proposes a cache masking scheme by allocating the most significant bit of address not used in 32-bit address system as indicator bit to designate non-cacheable address. As this scheme enables non-cacheable area designation every address, the simpler in the aspect of hardware and more flexible size of non-cacheable area can be obtained.

오늘날 국내 금융시장은 정택 및 규제에 대한 변화와 구조조정 및 인수 합병을 통한 금융회사의 대형화와 금융상품간의 복합 및 연계된 종합금융서비스를 제공하는 등의 급격한 환경 변화를 겪고 있다. 이러한 환경변화 속에서 금융 시스템 운영의 주체가 되는 마스터 데이터가 각각의 시스템에 개별적으로 관리되고 있어 이로 인해 금융 데이터의 품질 관리에 어려움이 생기게 되고 데이터의 중복 및 일관성에 문제가 생기게 되었다. 본 논문에서는 자크만 프레임워크를 활용한 통합 마스터 데이터 관리시스템을 제안한다. 이러한 마스터 데이터 관리를 통해 데이터 중복 및 데이터 정합성 보장, 시스템 연계간의 유연성을 확보하는 기대 효과를 예상할 수 있다.

A large scale automated material handling system (AMHS) is simulated using real industrial input data to analyze its performance so that one can scrutinize the critical factors that affect the AS /RS performance. The factors included in this study are line balancing efficiency, the distance between machines, and cycle time of the machines. The performance of AS /RS is measured in terms of R/M utilities that are latter used to classify the AS/RS structure into three types such as Good, Normal, and Poor. Among the three factors considered in this study, the line balance efficiency within each AS/RS is found as the most critical factor which statistically affect the AS/RS performance.

This paper presents the development of interactive graphical software for the educational purpose of power flow(PF) calculation. The developed software is specially designated to give a beginner the interest on PF problem as well as to increase the understanding of it with ease. the software developed in this paper is basically composed of the pull-down menu driver, in which various functions, such as Program Master, Data File Management, Case Study Option, PF Run and View Output, are prepared to handle the software easily and thus to be familiar with power flow calculation. A special design is also considered for interactive operation of the software, wi th which user can interrupt the computation process of PF to control the convergency of PF algorithm, With this function begineer can acquire the understanding of convergency characteristics and numerical sensitivity of PF algorithm as well as basic concept of its computation logic. Futhermore, various graphic illustrations is also provided to review and compare the computation results on monitor.

The work-order performs an important role in make-to-order production. The development of work-order system in this production is more complex than work-order system in planing production. To construct work-order system, load of directors for work-order must be decreased, and production management between scheduling of master plan and current workshop conditions must be considered. In this study, we grasped troubles in present work-order system and flows of information for work order. Using these results are made database schemas and data flow diagrams for effective development of work-order system. And then, for successful establishment of work-order system and actual use of directors, we considered systematic and easy user-interface. For a case study, development procedures of work-order system are presented for plant factory.

Background: The objective of this study is to find temporal trends in the associations between cardiovascular disease and occupational risk factors in the context of the Canadian population. Methods: Population data were analyzed from the Canadian Community Health Survey (CCHS) collected between 2001 and 2014 for trends over time between heart disease and various occupational risk factors: hours worked, physical exertion at work, and occupation type (management/arts/education, business/finance, sales/services, trades/transportations, and primary industry/processing). Results: We found no significant difference in the average number of hours worked/wk between individuals who report having heart disease in all years of data except in 2011 ($F_{1,96}=7.02$, p = 0.009) and 2012 ($F_{1,96}=8.86$, p = 0.004). We also found a significant difference in the degree of physical exertion at work in 2001 ($F_{1,79}=7.45$, p = 0.008). There were statistically significant results of occupation type on self-reported heart disease from 2003 to 2014. Conclusion: Canadian data from the CCHS do not exhibit a trend toward an association between heart disease and the number of hours worked/wk. There is an association between heart disease and physical exertion at work, but the trend is inconsistent. The data indicate a trend toward an association between heart disease and occupation type, but further analysis is required to determine which occupation type may be associated with heart disease.
