메타인지는 자신의 인지와 학습활동에 대한 지식과 통제활동의 의미로 사용되었으며, 메타인지 지식은 자기 자신의 인지과정에 대하여 스스로 알고 있는 지식을 의미하고, 메타인지적 기능인 자기 조정능력은 학습활동을 스스로 조정하고 통제하면서 학습을 수행하는 능력을 말한다. 학습정보를 제공하는 피드백이 학습자의 학업성취도를 높인다는 연구들은 교수 학습의 과정에서 피드백이 학습효과를 높이고 학업성취도를 증가시키는데 공헌할 수 있다고 밝히고 있다. 이러한 메타인지와 피드백에 관한 선행연구들을 바탕으로 웹을 기반으로 한 프로젝트 학습에서 학습자의 베타인지 수준에 따라 효과적으로 활용할 수 있는 피드백 유형이 필요함을 제안한다.

S-S-M(Server-Surrogate PC-Mobile Client)과 같은 3-계층 구조에서 이동 클라이언트를 이용한 공간 데이터 변경을 위해 대리트랜잭션 모델이 소개되었다. 이 모델에서는 이동 클라이언트의 공간 데이터변경을 위한 트랜잭션간의 동시성 제어를 위하여 전통적인 낙관적 병행 기법인 확인 기법을 확장하였다. 분산 환경에서는 참여자가 완료를 요청하면 조정자는 데이터를 공유하는 모든 참여자에게 완료 또는 취소 여부를 물어 최종 완료를 수행하였으나S-S-M 환경에서는 이동 클라이언트가 서버와의 접속을 해제하고 데이터를 변경한다. 따라서, 본 논문은 이동 클라이언트의 변경 완료 요청을 대리 PC를 통해 서버로 전달하고, 서버는 해당 트랜잭션의 충돌 여부를 검증하여 완료 또는 취소하는 완료 규약을 제시하고 이를 검증하기 위해 설계 및 구현한다.

The purpose of this study is to analyze the effect of commuter's departure time on transportation system in future traffic system operated autonomous vehicle using agent based model. Various scenarios have been set up, such as when all passenger choose a similar departure time, or if the passenger chooses a different departure time. Also, this study tried to analyze the effect of road capacity. It was found that although many of the scenarios had been completed in a stable manner, many commuters were significantly coordinated at the desired departure time. In particular, in the case of a reduction in road capacity or in certain scenarios, it has been shown that, despite excessive schedule adjustments, many passengers are unable to commute before 9 o'clock. As a result, it is suggested that traffic management and pricing policies are different from current ones in the era of autonomous car operation.

This paper investigates how firms adjust wages, employment and hours in response to demand shifts. It focuses on rigidities and asymmetries in such adjustments. Major findings are as follows. First, wage adjustments are fairly small compared with worker adjustments. Second, wage adjustments are asymmetric with respect to sales growth: there is no responsiveness of wage growth when sales are declining, while adjustments are significantly positive when sales are rising. On the contrary, worker adjustments are symmetric with respect to demand shifts. Third, while workers are linearly adjusted to the sales growth, some nonlinearity is observed in the wage adjustment. Fourth, hours are generally nonresponsive to demand shocks. Finally, union firms cut wages rather than workers in the face of negative demand shocks.

Constitutional issue of economic order has fiercely been disputed around the world and through the ages. In Korea, there also has been endless argument on to what extent the government should intervene in the economy through regulation. Article 119 of the Constitution of the Republic of Korea has its basis on the principle of free market economy, exceptionally allowing the government to intervene and coordinate in certain situations. The Constitution empowers the government with the authority of regulation and coordination to execute the Constitutional value of guaranteeing and securing fundamental human rights. Therefore, the government, as a fair and just mediator, should perform its mission to democratize the economy as well as secure market freedom and creative initiative.

International construction contractors are often faced with the situation of working in an unfamiliar construction environment. Under FIDIC rules, the contractor has the right to make a claim requesting the consulting engineer for an adjustment to the contract price or the time for completion when a part or parts of the works have changed, or in the event of unforeseeable conditions. Contractors generally have more access to the costs and time implications of such a change or unforeseeable conditions than the consulting engineer or outside neutrals. Due to such an asymmetry of information, the contractor may be motivated to dispute frivolous claims of less merit, expecting erroneous judgments by the consulting engineer or the neutrals. In this paper, a claiming behavior model is presented by using game theory and experience data to study the manner in which frivolous claims develop into disputes. The model also analyzes the impacts of DAB/DRB upon the frivolous claims.

본 연구는 미국 소재 T 대학교의 학생아파트를 대상으로 하여 창밖으로 보이는 외부 환경의 차이와 거주자의 환경조절 행태 사이의 관계를 분석하는 관찰연구로 진행되었다. 거주자와 거주환경간에 발생하는 부조화는 환경 스트레스의 한 원인이 된다. 이러한 환경 스트레스에 대한 대응 전략으로 거주자는 그들의 환경을 조정하곤 한다. 본 연구는 실내에서 식물을 키우거나 거주자의 취향에 따라 커튼을 교체하는 등의 환경조절 행태를 분석의 대상으로 한다. 창문과 현관 영역에서 발생하는 환경조절 행태의 정도를 비교 관찰하기 위해 군집형과 일자형으로 되어 있는 두 개의 배치 유형을 연구의 대상으로 선정하였다. 군집형 유형(cluster type: type A)은 상대적으로 도로에 가깝고 거실 창문의 조망이 다른 건물에 가로막혀 있으며, 일자형 유형(parallel type: type B)은 가로막고 있는 건물이 없어 자연경관을 거실 창문을 통해 조망할 수 있는 배치상의 두드러진 차이점이 있다. 관찰연구를 통해 군집형 유형에서 일자형 유형보다 더 높은 빈도로 식물 화분과 개별 커튼 등을 이용한 개인적 환경조절이 이루어진 흔적이 발견되었다. 이러한 결과는 창문을 통해 보이는 외부 경관의 특성이 거주자의 환경조절 행태에 미치는 영향의 정도를 암시하고 있다. 결론적으로 관찰연구에서 나타난 거주자의 환경조정 행태를 반영하여 디자인 고려사항을 제안하였다.

The relationship between suppliers and customers is treated importantly not only in the traditional business-to-business (BtoB) commerce but also in today's Internet environments. On the one hand, most of Internet-based BtoB commerce services like customer-centric e-procurement, supplier-centric e-sales or intermediary-centric e-marketplace focus mainly on the selection of partners according to bidding, auction, etc. This point may result in the problem of overlooking the relationships between suppliers and customers. To overcome this problem in this paper, an intelligent agents-based supply chain operation architecture is proposed and appraised considering the relationship and its adaptation.

From 2010 years to 2013, the selection method of successful bidder has been changed design suitable lowest method, comprehensive evaluation method(bid price adjustment, design score adjustments, weight standards), fixed amount best design method. Therefore this study was presented by analyzing the impact on the domestic construction industry according the way to determine the successful bidder, the evaluation order method and the operational issues through the analysis of order status, order number, results of acceptance an order, success rate range, results of acceptance an order according to weight success rate, results of acceptance an order by work type and order institution of a turnkey alternative tendering construction performed in domestic civil part.

This thesis suggests a new algorithm to detects multiple moving objects using a CMODE(Correct Multiple Object DEtection) method in the color images acquired in real-time and to track the interested pedestrian using motion and hue information. The multiple objects are detected, and then shaking trees or moving cars are removed using structural characteristics and shape information of the man , the interested pedestrian can be detected, The first similarity judgment for tracking an interested pedestrian is to use the distance between the previous interested pedestrian's centroid and the present pedestrian's centroid. For the area where the first similarity is detected, three feature points are calculated using k-mean algorithm, and the second similarity is judged and tracked using the average hue value for the $3{\times}3$ area of each feature point. The zooming of camera is adjusted to track an interested pedestrian at a long distance easily and the FOV(Field of View) of camera is adjusted in case the pedestrian is not situated in the fixed range of the screen. As a experiment results, comparing the suggested CMODE method with the labeling method, an average approach rate is one fourth of labeling method, and an average detecting time is faster three times than labeling method. Even in a complex background, such as the areas where trees are shaking or cars are moving, or the area of shadows, interested pedestrian detection is showed a high detection rate of average 96.5%. The tracking of an interested pedestrian is showed high tracking rate of average 95% using the information of situation and hue, and interested pedestrian can be tracked successively through a camera FOV and zooming adjustment.
