  • A u-city is a vision of a city with computers and sensors built in to its infrastructure, and data sharing among the various information systems. A u-City provides several u-City services to the u-City clients. The u-City services for local governments contain two types of functions: common function and specified function. It is needed a study on generation of specified service models of local governments. The proposed service model divides functions of the city into two service areas: common support service and specified support service. And we suggest the way to generate the u-services of each local government in this paper.

  • Understanding 3D structure of scenes is of a great interest in various vision-related tasks. In this paper, we present a unified approach for estimating depth from a single monocular image. The key idea of our approach is to take advantages both of parametric learning and non-parametric sampling method. Using a parametric convolutional network, our approach learns the relation of various monocular cues, which make a coarse global prediction. We also leverage the local prediction to refine the global prediction. It is practically estimated in a non-parametric framework. The integration of local and global predictions is accomplished by concatenating the feature maps of the global prediction with those from local ones. Experimental results demonstrate that the proposed method outperforms state-of-the-art methods both qualitatively and quantitatively.

  • Local Binary Pattern (LBP) is becoming a popular tool for various machine vision applications such as face recognition, classification and background subtraction. In this paper, we propose a new extension of LBP, called the Diagonal LBP (DLBP), to handle the image-based gender classification problem arise in interactive display systems. Instead of comparing neighbor pixels with the center pixel, DLBP generates codes by comparing a neighbor pixel with the diagonal pixel (the neighbor pixel in the opposite side). It can reduce by half the code length of LBP and consequently, can improve the computation complexity. The Support Vector Machine is utilized as the gender classifier, and the texture profile based on DLBP is adopted as the feature vector. Experimental results revealed that our approach based on the diagonal LPB is very efficient and can be utilized in various real-time pattern classification applications.

  • Edge detection in image processing and computer vision is one of the most fundamental operations. Canny edge detection algorithm has excellent performance and is currently widely used. However, it is difficult to process the algorithm in real-time because the algorithm is complex. In this study, the equations required in the algorithm were simplified to facilitate hardware implementation, and the calculation speed was increased by using a parallel structure. In particular, the size and management of local buffers were selected in consideration of parallel processing and filter size so that data could be processed without bottlenecks. It was designed in verilog and implemented in FPGA to verify operation and performance.

  • Since its foundation in September 1986, the Korean Society of Water and Wastewater has made a significant contribution to the water sector in Korea over the past 30 years. The 30th anniversary commemorative committee reviewed the establishment goal of the society and its development strategy for organization and present the "Future Vision of Korean Society of Water and Wastewater" for the next 30 years. The future vision of the society is defined as "Aiming for the healthy life and preservation of the environment through the development of water and wastewater technology and experience". Promotion strategies for implementing the future vision are as follows: 1. Leading water and wastewater technology, 2. Develop water and wastewater policy, 3. Strengthen water and wastewater capacity, 4. Reinforce institutional governance. The driving target to be achieved through the implementation strategy is "To lead the global standards of water and wastewater." We also presented national issue, policy issue, and technical issues in the water sector. Climate change, unified Korea, water safety, and national welfare were selected as national issues related to water and wastewater. This approach was taken from the perspective of policy consumers such as citizens, civil society, experts, and local government/industry. By presenting policy issues and technical issues that address national issues, authors have proposed a future policy direction for the Korean Water and Wastewater Society to make critical contributions to national development.

  • The first local exchange trading system(LETS), established in Comox Valley in Canada, aimed at facilitating the regional economy. However, in Korea, LETS was adopted to encourage mutual aid and promote community spirit among residents. This study examines the feasibility of LETS as a revitalization initiative for Pumasi and suggests a number of policies that can be implemented to support the project. The findings are as follows: First, the LETS credit system was found to complement social capital initiatives among Pumasi participants in the early stages of the Pumasi project. Second, combining LETS and Pumasi initiatives was found to consolidate community spirit and encourage a cooperative way of life among participants due to the fact that LETS enlarges the scope of local residents' participation and diversifies the services being exchanged. A number of policy suggestions are made for combining LETS with Pumasi. First, the project must define a vision of its long-term purpose and outcomes. Second, local residents should be employed as assistants to facilitate the project. Third, Pumasi participants should ensure that childcare exchange services are of the highest quality by providing an educational program on parenting. Fourth, the project manager's employment conditions and working environments must be guaranteed.

  • Community revitalization programs in New York State are community centralized projects, and this approach is pretty much general in the united states. However, local communities do not have enough funds, human resources, technical knowledge and useful data. Even though State governments have their own supporting systems, they are not able to support all that communities need and ask. State governments are, on the other hand, trying to develop the most efficient supporting system for the community revitalization programs as a part of community development. US federal government supports funds as well. New York state government makes connections with other states, local governments, universities, and other useful groups, and reorganizes all possible resources for New York state communities. This supporting system helps that local leaders and community residents can tackle regionally specific issues and opportunities. This paper shows how New York state implements community revitalization programs with the community supporting system. This research also shows how to organize and manage the community involvements in the planning process through the case study of the Black River Vision Plan/ City of Watertown that an author had participated in.

  • Debates continue to multiply on the definition and rationale of Southeast Asia as a region and on the utility of the multidisciplinary field of area studies. However, we have now entered a post-colonialist, post-Orientalist, post-structuralist stage of reflection and re-orientation in the era of globalization, and a strong tendency on the part of insiders to pose these issues in terms of an insider-outsider dichotomy. On the one hand, the study of Southeast Asia for researchers from outside the region has become fragmented. This is for very obvious reasons: the strengthening and re-energizing of academic disciplines, the increasing popularity of other non-regional multidisciplinary studies, and the entry of globalization studies into our field of vision. On the other hand, how has the local Southeast Asian academy addressed these major issues of change in conceptualizing the region from an insider perspective? In filling in and giving substance to an outsider, primarily Euro-American-Australian-centric definition and vision of Southeast Asia, some local academics have recently been inclined to construct Southeast Asia in terms of the Association of Southeast Asian Nations (ASEAN): a nation-state-based, institutional definition of what a region comprises. Others continue to operate at a localized level exploring small-scale communities and territories, while a modest number focus on sub-regional issues (the Malay-Indonesian world or the Mekong sub-region are examples). However, further reflections suggest that the Euro-American-Australian hegemony is a thing of the past and the ground has shifted to a much greater emphasis on academic activity within the region. Southeast Asia-based academics are also finding it much more important to network within the region and to capture, understand, and analyze what Chinese, Japanese, and Korean scholars are saying about Southeast Asia, its present circumstances and trajectories, and their increasingly close involvement with the region within a greater Asia-Pacific rim. The paper argues that the insider-outsider dichotomy requires considerable qualification. It is a neat way of dramatizing the aftermath of colonialism and Orientalism and of reasserting local priorities, agendas, and interests. But there might be a way forward in resolving at least some of these apparently opposed positions with recourse to the concepts of culture and identity in order to address Southeast Asian diversities, movements, encounters, hybridization, and hierarchies.

  • Blepharoplasty is one of the most commonly performed aesthetic procedures. Surgical complications are rare, but can have severe consequences, such as permanent vision loss. In this report, we describe a patient who developed primary angle-closure glaucoma (ACG) with associated vision loss after a oculoplastic procedure using local anesthesia. So far, six similar cases have been described in the literature. It is believed that acute ACG is triggered by the surgical procedure in patients with predisposing risk factors such as a cataract. Surgical triggering factors include the use of buffered lidocaine/xylocaine with adrenaline/epinephrine, stress, and coverage of the eyes postoperatively. Due to postoperative analgesic use, the clinical presentation can be mild and atypical, leading to a significant diagnostic delay. Acute ACG should therefore be excluded in each patient with postoperative complaints by assessing pupillary reactions. If a fixed mid-wide pupil is observed in an ophthalmologic examination, an immediate ophthalmology referral is warranted. Surgeons should be aware of this rare complication in order to offer treatment at an early stage and to minimize the chance of irreversible vision loss.

  • In the car industry, welding is a fundamental linking technique used for joining components, such as steel, molds, and automobile parts. However, accurate inspection is required to test the reliability of the welding components. In this study, we investigate the detection of weld beads using 2D image processing in an automatic recognition system. The sample image is obtained using a 2D vision camera embedded in a lighting system, from where a portion of the bead is successfully extracted after image processing. In this process, the soot removal algorithm plays an important role in accurate weld bead detection, and adopts adaptive local gamma correction and gray color coordinates. Using this automatic recognition system, geometric parameters of the weld bead, such as its length, width, angle, and defect size can also be defined. Finally, on comparing the obtained data with the industrial standards, we can determine whether the weld bead is at an acceptable level or not.
