With more than 100 years exploration and development of offshore oil, more and more offshore oil fields will gradually lose the economic profit to operate. In this article, to take the target oil field for example, the procedure of decommissioning for FPSO, TCMS, subsea system and well abandonment have been analyzed. Meanwhile, the environment impact and mitigation measure have been proposed. The successful project experience will provide a guide line for the offshore facilities decommissioning and abandonment.

In this paper, we introduce a mathematical model to analyze pricing/quality and service mix strategies for Internet Portal site. This model includes utilities and costs of each participants, i.e., user, third party provider, and portal sites. Especially, we consider portal sites that initiate their businesses by providing free services like free e-mail service or search service and providing several charged services. As the results, we can find that Portal sites should make the target of customers and focus them to maximize their profit. Portal sites should pay their marketing effort not for all customers but pertinent portions of customers. And Portal sites should make more efforts to efficiently develop and provision their services.

This paper presents the greenhouse gas emission trading scheme which is under progress as a pilot project at the power sector in preparation for UNFCCC. By referring UK's, Emission Trading is introduced incentive auction to maximize the reduction of greenhouse gas emission. At the 1st step, from year 2006 to 2008, only CO2 is regarded as an objective target to decrease but emission credit is excluded with an assumption and only 5 Generation company take part in as participants. The market operating procedure is composed of participants' registration, baseline verification, incentive auction, the registration of initial and yearly allocation, emission trading, yearly emission verification & approval, yearly obligation conformity, carry forward & incentive grant. It can be serve a guideline the whole aspects of emission trading which will start in 2006 including operation, verification and profit sharing.

CRM(Customer Relationship Management : CRM) is an advanced marketing supporting system which analyze customers\` transaction data and classify or target customer groups to effectively increase market share and profit. Many engines were developed to implements the function and those for classification and clustering are considered core ones. In this study, an improved clustering method based on SOM(Self-Organizing Maps : SOM) is proposed. The proposed clustering method finds the optimal number of clusters so that the effectiveness of clustering is increased. It considers all the data types existing in CRM data warehouses. In particular, and adaptive algorithm where the concepts of degeneration and fusion are applied to find optimal number of clusters. The feasibility and efficiency of the proposed method are demonstrated through simulation with simplified data of customers.

The construction market condition is getting worse because of global constructions slow down, low profit, market contraction and so on. For these reason, most construction companies depend on public construction projects which possible to protect construction fee, known as progress payment, by laws. Despite this law, problems of progress payment are constantly occurring and it has been main factors that hinder the construction cost's cash-flow in construction project. To solve this problem, many researchers suggested various solutions but most of solutions were focused on specific target as owner, general contractor, and subcontractor. So, most of solutions were insufficient consider about interaction between contractors. Because of these reasons, it was hard to reflected policy. This research aimed to use system dynamics to develop the model for the application and payment based on the regulations and papers. Also, performed a developed model's verification based on progress payment regulation's basic objectives.

디지털 게임의 부분유료화 모델은 플레이어로 하여금 신규 게임 유입의 장벽을 낮추고 동시에 소액 결제를 통해 소비를 유도하여 안정적인 수익을 촉발한다는 점에서 게임 업계의 대표적인 수익모델로 평가받고 있다. 하지만 부분유료화를 통해 제공되는 서비스들의 종류와 적용 대상, 적용 양상이 다양해지면서 있는 플레이어들의 게임 플레이 경험에 불균형을 양산하는 문제를 만들고 있다. 이에 본 논문은 부분유료화의 개념과 특징을 정리하고, 획득방법, 지속성, 기능 발현 대상에 따라 2가지 유형, 7가지 세분류를 진행하였다. 이 과정을 통해 부분유료화 모델이 가지는 세 가지 문제점을 도출할 수 있었는데 첫째, 게임 플레이 경험의 불평등 유발, 둘째, 게임 세계 경제의 불균형 양산, 셋째 게임 플레이 지속성 파괴가 바로 그것이다. 본 논문에서는 이 세 가지 문제점을 구체적인 사례를 중심으로 설명하고 그 해결책을 제언하는 것을 목적으로 한다. 이러한 연구는 앞으로의 부분유료화 모델이 한국 게임 시장에 어떤 방식으로 적용되어야 하는지에 대한 지표를 제공한다는 점에서 의의를 찾을 수 있다.

최근 알고리즘 트레이딩에 대한 관심이 높아지면서, 인공지능 방법론을 이용한 매매 전략 구축에 관련된 연구들이 활발하게 진행되고 있다. 하지만 복수의 인공지능 방법론을 융합하여 매매 전략 개발에 이용한 사례는 아직 많지 않다. 본 연구는 주가지수선물시장을 바탕으로 인공지능 방법론 중 하나인 러프집합 이론을 적용하여 알고리즘 트레이딩 매매전략을 개발한다. 특히 유전자 알고리즘을 도입하여 생성된 매매전략을 현재시장상황에 최고의 수익률을 보일 수 있도록 최적화한다. 실증분석으로는 2009년부터 2012년까지 4년간의 매매수익률을 분석한 결과 매수 후 보유 전략과 비교하여 우수한 성과를 보였다.

This article was written with two purposes in mind. The first purpose was to introduce clothing and textile community who may not be familiar with Multidimensional Scaling(MDS) with usefulness of the new technique in the area of fashion merchandising. The second purpose was to present the results of an empirical study on brand image utilizing MDS and its related technique as the main analysis tools. The main objective of the empirical study was to gain a better understanding of consumer's brand image by relating differences in perception and attributes of clothing in women's ready-to wear market. For this empirical study, the ten brands and the fifteen attributes of clothing were chosen. The questionnaire consisting of questions asking about the similarity and attributes of clothing between selected brands was administrated to 185 career women during summer in 1989. Data were analyzed cluster analysis, and KYST and PROFIT in MDS program. The results were as follows: 1. The similarities data for the ten selected brand by using KYST program of MDS drawed the perceptual map. The results of this perceptual map showed that the selected brand were grouped into three clusters. 2. In order to get a somewhat objective view of which attributes consumers are attributing to each brand, PROFIT program was used. As a result, it was revealed that assortment depth / width, price, youth-oriented style, possibility of various social activity were significant attributes in consumer's brand choice rather than physical attributes of clothing such as quality or durability. This may imply that consumer orientation in rapidly changing environments of women's apparel market was its basic idea, and the focus of all fashion merchandising activities was put on need's and the response of consumer group who are the object of the target. Implicating for future research as well as for strategy of brand positioning were also suggested.

건설산업의 환경은 대형화, 전문화의 추세와 공사이행기간의 증가와 건설공사의 입찰에 있어서 중요한 리스크 요인과 불확실 요인이 존재하게 되었으며 하도급자의 판단오류 및 인식부족은 이윤감소 혹은 적자를 초래하게 되며, 이는 결과적으로 하도급자에게 재정적 부담을 주게된다. 따라서 입찰단계에서의 리스크요인에 의한 공사예비비 산정을 예측하고 계약의 합의와 이행 과정에서 하도급자의 목표이윤 확보를 고려한 입찰단가를 산정하는 것은 매우 중요하다. 이러한 취지에서 본 연구는 하도급자의 공종별 사례로 선정하여 입찰금액 산정에 미치는 리스크에 대한 중요도가 공사비에 미치는 영향정도를 기초로 하여 분석하고, 이를 바탕으로 하도업자의 합리적인 입찰전략을 수립하는 기초자료로 활용하는데 있다.
