오늘날 디지털 기술의 발달로 인터넷이 대중화되었고, 인테넷 이용자가 증가함에 따라 인터넷을 이용한 광고가 증가하고 있다. 특히 인터넷을 이용한 광고는 시간에 관계없이 고객과 기업이 쌍방향(interactive) 커뮤니케이션이 가능하여, 제품의 특성이나 회사에 대한 이미지를 고객에게 능동적이고 효과적으로 제공할 수 있다는 특징을 가지고 있다. 이렇게 인터넷 광고는 시간에 상관없이 불특정 다수 인터넷 접속자에게 시선을 끌 수 있다는 주목도(Attention)와 쌍방향 커뮤니케이션이 가능하다는 매력(Charming)이 있어서, 인터넷 이용자가 보다 더 손쉽게 참여(Easy to Participation)를 할 수 있다. 현재 인터넷 광고의 주를 이루는 베너광고나 그 외의 광고는 인터넷 유저와 상호작용이 활발하지 못하다. 게임의 가장 중요한 요소가 상호작용이라는 점을 인터넷 광고에 이용한다면 더욱 효율적인 광고가 될 수 있다. 이러한 점에 착안하여 본 연구자는 인터넷 광고의 특성과 게임의 상호작용성을 토대로 하여 게임 성향의 인터넷 광고의 실제 디자인 프로세스 사례를 제시하고자 한다.

Autonomous system (AS) business relationships and their inference have been widely studied by network researchers in the past. An important application of inferred AS relationships can be the prediction of AS paths between a source and destination AS within a model. However, besides knowing the topology and inferred AS relationships, AS path prediction within a model needs to be understood in order for us to know how we can derive border gateway protocol (BGP) policies from AS relationships. In this paper, we shed light onto the predictive capabilities of AS relationships by investigating whether they can be translated into BGP policies such that inferred AS paths are consistent with real AS paths, e.g., paths observed from BGP routing tables. Our findings indicate that enforcing constraints such as the well-known valley-free property and the widely assumed preference of customer routes always results in a very low consistency for AS path inference. In addition, this is true irrespective of whether customer, peer, or provider routes are preferred. Apparently, applying such constraints eliminates many "correct" paths that are observed in BGP routing tables and that are propagated in a simple shortest path model where AS relationships are ignored. According to our findings, deriving BGP routing policies for predicting with high accuracy AS paths in a model directly from AS relationships is still difficult.

우리나라 의료 시스템에서 고객만족은 매우 중요한 요소로 자리 잡고 있다. 하지만, 의료영상 분야는 일반인들이 이해하기 매우 어려운 부분이 있다. 이에 본 연구에서는 의료진과 환자의 소통문제를 해결하기 위한 방안으로 기존의 PET/CT 단면 의료영상을 Volume Rendering Technique으로 재구성 하여 환자의 만족도를 증가시키고자 하였다. PET/CT 검사를 진행한 암 환자 360명을 대상으로 VRT을 진행하였으며, 이 중 100명의 환자를 대상으로 만족도 조사를 실시한 결과 100명 모두 VRT 영상이 기존의 영상보다 만족도가 우수한 것으로 나타났다. PET/CT는 CT 나 MRI와 같은 세부적인 해부학적 모양을 관찰하는 장비가 아닌 암의 신호를 강하게 나타내는 영상으로 손쉽게 VRT 영상이 제작 가능하다. 이러한 VRT 영상은 일반인들도 쉽게 이해할 수 있도록 입체적으로 표현 할 수 있어 의료진과 환자의 소통을 보다 효율적으로 높일 수 있으며 환자의 "알 권리" 충족시킬 것으로 나타났다.

1990년대 중반 이후 국내·외 유통기업의 적극적인 유통산업 진출로 중소 유통소매업은 어려움을 겪고 있었다. 이에 정부는 2003년 중소 유통소매업의 자생력 확보 및 경쟁력 강화를 위해 중소유통물류센터를 건립하였다. 하지만 급변하는 유통환경 속에서 중소유통물류센터는 점점 더 어려워지고 있었다. 중소유통물류센터 경영역량 강화를 위해 문헌연구와 FGI를 기반으로 4개의 1차 요인(경영자의 운영능력, 직원의 전문성 역량강화, 상품배송, 고객 CS관리)과 16개의 2차 요인을 설정하였다. AHP를 이용하여 이 요인들의 최종 가중치와 우선순위를 도출하고, 중소유통물류센터의 경쟁력을 강화할 수 있는 전략들을 수립하고자 한다.

Nowadays, globally high-grade companies have done their best for increasing their competitive power through a many kinds of method in incisive competition for making certain of a pacesetting position. Among the rest, Six Sigma have been the best methodology of improving process and have proven to be effective by the result of improving process in many of manufacturing business, however, it has not obtained excellent results in the transaction business. In transaction business, a $30\sim50%$ costs in total costs is generated by slow-speed working and reworking. The slow processes decrease the quality and increase the cost, which decreases customer satisfaction, and finally the income is decreased. All of them are so called wastes in processes. For this, adopting of lean six sigma methodology in process management can eliminate the wastes and reduce the variation. This study focuses on distribution with the domains like capacity, layout, amount of location, assignment of product, operation procedure and operation rule in order to improve these domains, we make a further application of eight analysis ways based on DMAIC method for improving operation of processes of distribution center as the third profit source. The goal of this study is to trace an approach that can easily adopt of Lean Six Sigma in operational management of distribution center by a kind of data, analysis method and template.

Generally EPC management system was simply management concept through the normal S/W. Our LNG Plant R&D Center wanted to the excellent management system from the S/W. So We developed the R&D management S/W and EPC management S/W Built in the Microsoft Project Server. Our system made to the customer Requirements. It was just User Interface protocol. But User Interface has more Weak position, because it makes from the MS Project Servers. Ms Projector server make easy to treat the project on the WBS. EPC parts mixed WBS and normally Ms SQL Database. It has very complicated Structures. Now We planed to make the general Database and Ms Project Server, It' means to the S/W Developer and Schedule Manager ability. We will successfully integrate R&D management system and EPC system and other softwares.

To evaluate the autofocusing performance of recent mobile phone cameras, it is necessary to determine the peak position of the center field MTF (Modulation Transfer Function), -known as the through focus MTF- of the module. However, the MTF peak position found by conventional methods deviates from the ideal position due to the focus scanning resolution of mobile phone cameras. This inaccurate peak position results in false judgements of the optical performance, leading to yield losses or customer complaints. An increase in the focus scanning resolution can address this problem, but the manufacturing UPH (Unit per Hour) level will also unfortunately increase as well, resulting in a loss of manufacturing capabilities. In this paper, several fitting models are studied to find an accurate MTF peak position within a short period of time. With an analysis of a large amount of manufacturing data, it is demonstrated that the fitting methods can reduce false judgements and simultaneously increase the capabilities of the manufacturing system.

In order to increase the productivity of the logistics center and transportation, we try to articulate the priority ranking factors of the productivity influenced by the personality of the field workers (logistics center workers) and functional workers (drivers) via the AHP technique Individual personality was studied by applying the Big 5 model of psychological factors (openness, Conscientiousness, extroversion, Agreeableness, neuroticism). In this paper, extraversion was critically analyzed as a priority factor. A trait of extroversion is a strongly active and individual personality. In this study, the field workers are logistics center workers and the functional workers are drivers. They are interactively influenced in the In & Out operation. For example, when it comes to 'up and down work' and 'inspection work', the functional workers perform 'up and down work' and 'delivery work' and the field workers perform 'inspection work'. Stressing on the respective work has an affect on work productivity. Inspection workforce has something to do with inventory management. Functional workforce affects the delivery workforce. Delivery work is positively correlated with customer satisfaction. Nevertheless, as a result of research, extrovert personality that has something to do with an energetic activity would not affect on the implementation of their operation. In addition, personal extraversion of workers and drivers in the warehouse can have a significant impact on job commitment and productivity improvement.

This paper will introduce the development case study about virtual-reality-based operation training system for steel making process. Steel making process consist iron making process to create liquid steel, pig iron, by reduction process, steel making process to make molten steel by refining, continuous casting process to make slab, and rolling process to make final product like coil, plate. This steel making process deals with liquid and solid products, so facilities of steel making process are very various and complicated. In addition, according to various customer requirements, the recycle of facilities and recipes changing have been fast. So the training for skilled operators is very important point. In this paper, we develop steel making training system based virtual reality for training skilled operator. This system consists of virtual machine, virtual HMI, and virtual control panel. And for fitting the characteristics of each process and increasing the education effectiveness, we develop dynamic methods like the method of dynamic education system configuration, initial facilities setup operation education system, and etc.
