This study aims to understand history and adaptive strategies of Bitgoul iCOOP Consumer's Coopertive Association(BCCA). BCCA have twofold identity as civil society organization and economic management organization. Going through several ups and downs from the founding up to now date, BCCA has adapted successfully. The numbers of association member have steadily increased and activity areas have extended consistently. Moreover united activity with local civil society have expanded both quantitatively and qualitatively. These success results from store business which stated from 2008. But maintaining successful management conditions, the numbers of association member should increase steadily and staff organization have grown in size. At the results, BCAA have been bureaucratized and recruitment of core staffs is difficult more and more.

The eco-tourism has caused a variety of problems between use and conservation. The situation requires introduction of scientific management techniques, such as controlling the number of visitors to the destination and identifying appropriate carrying capacity. Getz, LAC, VIM and VERP have been developed for this purpose and they are the management model based on carrying capacity that have been explored for introduction and application in Korea. However, it is necessary to modify and supplement the management model to suit the purpose of ecotourism characteristics and the status of ecotourism in Korea. Therefore, we identified the problems of the existing management model and presented three improvements. strengthen the interdependent linkages between carrying capacity and the management goals; improve the tourism opportunity distribution model; improve the phased management. It will help many ecotourism sites to effectively manage the impacts of visitors in Korea with a minimum amount of effort and costs.

IT convergence technology is gradually becoming anthropocentric and evolving based on the low-carbon green growth. Augmented reality technique is a contents convergence technology that can mix virtual objects while maintaining a sense of the real world. For that reason, interaction between user and system is possible, can make various applications, and has a high possibility for expandability. To expand the scope of existing interaction, this paper suggests contextual UX-based augmented reality system. It is a system which creates virtual objects that respond to the changes in the real world environment, and users can directly apply their personal preferences to virtual objects. Also, several virtual objects can be registered all at once, and even shows animations corresponding to either day and night according to the brightness of illumination. As said, it improves user's satisfaction through a system of mixed usability, and leads to a continuous use of augmented reality contents.

The Purpose of this study is to understand on the whole trend in the home economics instructions among the middle school. The study has been achieved through observing the actual classroom activities, and stating the results as objective as possible. In as much as clarifying the objectives of observing the classroom activities, it would be deemed effective to understand the overall outline of the home economics instructions, as well as to define the elements that make up the classroom work. Hence, the classroom work has been modularized in stage, namely. planning/organization, execution, and evaluation, as well as extracting nine(9) elements of the classroom work. Video-taped classroom activities, which have been used for this research analysis, consists of twelve(12) study classes, covering the subjects in food/nutrition, clothing, household management, daily life as a consumer, and housing management. The items in the study the items of checklist have been broken down further in an effort to develop a framework for analyzing the results of observing the classroom activities. Also included, in part, is the verbatim transcription of the videotaped classroom activities in progress.

In this paper, we propose a color correction technique for images acquired through a multi-view camera system for acquiring a 3D model. It is assumed that the 3D volume is captured indoors, and the position and intensity of the light is constant over time. 8 multi-view cameras are used, and converging toward the center of the space, so even if the lighting is constant, the intensity and angle of light entering each camera may be different. Therefore, a color optimization function is applied to a color correction chart taken from all cameras, and a color conversion matrix defining a relationship between the obtained 8 images is calculated. Using this, the images of all cameras are corrected based on the standard color correction chart. This paper proposed a color correction method to minimize the color difference between cameras when acquiring an image using 8 cameras of 3D objects, and experimentally proved that the color difference between images is reduced when it is restored to a 3D image.

Business expects that IT investment would maximize the effects, like availability, timeliness, rapidity of information, by practical using of information technology for a strategic goal. However, it is not clear yet that IT investment would increase business productivity and could create profitability in the end-the linkage between IT investment and business KPI(Key Performance Indicator). In this case study(only provides post-evaluation case), we suggested integrated IT ROI(Return On Investment) methodology with a consistent and integrated view, on the base of practical implementation at Korean financial company. Especially, we evaluated connection between IT and business strategy, made business-related IT KPI development methodology, suggested framework for sustainable IT evaluation and management.

This study aimed to examine the association between material hardship and alcohol use among low-income households in Korea, with particular attention to whether the association was mediated by family conflict and self-esteem. Using a nationally representative sample of 960 low-income households, this study conducted a path analysis to test a structural model liking material hardship to alcohol use through family conflict and self-esteem. The significance of indirect paths was tested by a Sobel test. This study found that experiencing material hardship was directly associated with low levels of coping skills for family conflict and low levels of self-esteem, but not with alcohol use. However, material hardship was indirectly associated with alcohol use through low levels of coping skills for family conflict as well as low levels of self-esteem. The findings of this study suggest that experiencing material hardship among low-income households would be a socio-structural stressor for alcohol use, particularly in that it increases secondary role and intra-psychic strains. Implications to address material hardship and alcohol use among low-income households were discussed.

본 연구는 한국어 기능 범주(functional category)의 처리를 살펴보기 위하여 실문법증 환자를 대상으로 실시되었다. 일반적으로 수형도에서 기능 범주는 보문소구(Complementizer Phrase), 시제구(Tenxe Phrase), 일치소구(Agreement Phrase)의 순으로 구성되어 있다. 본 실험은 Grodzinsky(1997)의 수형도 가지치기 가설과 실문법증의 엄밀성 척도를 바탕으로 한국어 기능 범주의 처리에 있어서도 두 가지 가설의 적용이 타당한지 여부를 검증하기 위해 실시되었다. 실험 1은 일치소(Agr)의 처리를 살펴보기 위하여 실시되었는데, 국어의 존칭 선어말 어미를 중심으로 살펴보았다. 국어의 존칭선어말 어미는 크게 '-시-'삽입에 의한 존칭과 다른 어휘로 대체하는 보충법에 의한 존칭으로 구분된다. '-시-'삽입에 의한 존칭은 AgrP의 범주로 보충법에 의한 존칭은 동사구(Verb Phrase)의 범주로 설정하여 문법에 어려움을 보이는 실문법증의 경우 어휘부에 혹하는 보충법에 의한 존칭을 문법범주에 속하는 '-시-'삽입의 존칭보다 더 잘 할 것으로 가정하였다. 실험 2는 AgrP의 범주인 '-시-'선택의 장애가 TPqja주인 시제 선택에 역시 영향을 미칠 것이라는 가정아래 설계되었다. 수형도 상에서 '-시-'는 일치소(Agr)로서 시제(TP)의 아래에 위치하므로 실험 3은 '-시-'삽입 존칭과 시제에서 어려움이 보문소(CP)의 선택에 역시 영향을 미칠 것이라는 가정하에서 실시되었다. 실험 1의 결과 '-시-'삽입에 의한 존칭을 처리하는데 보충법에 의한 존칭보다 어려움을 보였다. 실험 2의 결과 '-시-'삽입 존칭에 어려움을 보인 환자는 시제 선어말 어미를 선택하는데도 어려움을 보임이 확인되었다. 실험 3 역시 실험 1과 실험2에서와 동일하게 처리의 어려움을 보였다. 이러한 실험 결과들은 국어의 존칭과 시제 선어말 어미가 통사부에서 구(XP)와 결합하여 새로운 구를 형성하는 통사적 접사로 해석할 수 있으며 Grodzinsky의 가설을 지지하는 결과를 보여 줌으로서 국어에서도 AgrP, TP, CP 사이의 통사적 위계가 있음을 뒷받침하는 증거가 된다.

Unfolding is an efficient technique to detect colorectal disease since it represents entire shape of colon at a glance. However, the previous unfolding methods may miss the surface located behind the folds or high curvature areas. To solve the problem, we propose an adaptive unfolding method that controls the number of rays in accordance with the surface complexity. In the first step, we find sample points of longer and shorter distance between the sample points and the colon surface, and then determine them as based control points. Next, for reaching rays of sample points in the wrinkled colon surface, sample points are shifted toward the control points that have the long distance. Lastly, we perform a 2D scaling which solves local distortions of the unfolding surface and avoids missing surface. Consequently, our method could be visualized the hidden surface of colon organ in detail.
