Human tracking is a requirement for the advanced human-computer interface (HCI), This paper proposes a method which uses a component-based human model, detects body parts, estimates human postures, and animates an avatar, Each body part consists of color, connection, and location information and it matches to a corresponding component of the human model. For human tracking, the 2D information of human posture is used for body tracking by computing similarities between frames, The depth information is decided by a relative location between components and is transferred to a moving direction to build a 2-1/2D human model. While each body part is modelled by posture and directions, the corresponding component of a 3D avatar is rotated in 3D using the information transferred from the human model. We achieved 90% tracking rate of a test video containing a variety of postures and the rate increased as the proposed system processed more frames.

The technology of emotion recognition is a crucial factor in day of ubiquitous that it provides various intelligent services for human. This paper intends to make the system which recognizes the human emotions based on 2-dimensional model with two bio signals, GSR and HRV. Since it is too difficult to make model the human's bio system analytically, as a statistical method, Hidden Markov Model(HMM) is used, which uses the transition probability among various states and measurable observation variance. As a result of experiments for each emotion, we can get average recognition rates of 64% for first HMM results and 55% for second HMM results

This study applied Data Envelopment Analysis to a set of Korean Public Corporation Medical Centers and Japanese Municipal Hospitals to compare their relative human resource efficiencies. Based on the data provided on the inputs and outputs, the analysis showed Japanese municipal hospitals were relatively efficient than Korean hospitals. The result of analysing BCC model shows 5 hospitals in Japan and 7 in Korea with an efficiency rating of less than 1 as considered relatively inefficient. For the inefficient hospitals the manner in which inefficient hospitals may be made efficient were indicated by the managerial strategies based on dual variables. A subsequent analysis of Wilcoxon rank-sum test revealed that the medical revenue per medical expense, labor cost per value added revenue were statistically significant between efficient and inefficient Korean hospitals and medical revenue per medical expense, labor cost per value added revenue, bed occupancy rate, average length of stay, rate of personnel expenses per medical revenue were statistically significant between efficient and inefficient Japanese hospitals.

A method to visualize human body is proposed for various human pose. The method affords three 3D-styles of the same body: firstly, one which wares clothes specified from pattern of dresses, second, body shape, lastly bone structure of body. For this objective, standard body data are prepared which is constructed from CT images. Individual body is measured by 3D body scanner. The present status of our research is limited to offer still images, though we are engaged to accommodate various poses.

The purpose of this study is to compare the standards and guidelines of long-term care facilities based on the physical environments and human resources in Korea, Japan, USA, and Australia. Ultimately, this study suggests the directions for amendments of long-term care service or running of the facilities in Korea. For achieving this purpose, we reviewed the homepage of national health departments, reports and articles of long-term care service, and acts related with long-term care in each country. This comparisons were carried in terms of physical environments, human resources by long-term care related acts and legal sanctions as means of quality control. This study implies that long-term care service guidelines or standards should be revised for developing the quality of our long-term care services.

Empirical studies have shown that government and human service nonprofit organizations have maintained active partnerships to deliver human services for the past several decades. However, the previous researches on resource dependent government-nonprofit service delivery have revealed serious methodological limitations to adequately demonstrate the dynamic relationship between both sectors over time. Since the dynamics underlying the government-nonprofit service delivery is a complex process, in which multiple factors dynamically interact over time, the assumptions of system dynamics can help improve these methodological drawbacks. This study aims to explore methodological issues and weaknesses observed in empirical studies on resource dependent government-nonprofit service delivery in the United States, and further attempts to provide insights on future research toward a dynamic approach, bringing the assumptions of system dynamics to the challenges of the previous researches.

현재 IT서비스 업체에서 새로운 성장동력으로 떠오르고 있는 분야가 융복합사업(IT+IT, IT+장비, IT+장비+시공)이라고 불리우는 컨버전스 프로젝트이다. 기존의 IT분야의 프로젝트와는 전혀 다른 특성을 갖고 있는 컨버전스 프로젝트에 대한 IT서비스 업체의 준비는 아직 미흡한 것이 현실이다. LG CNS에서는 이런 현실에서 컨버전스 프로젝트의 특성에 맞추어 기존 프로젝트 관리자(Project Manager)의 역할을 재정의하고 이를 현장에 적용시키기 위해 그동안의 컨버전스 프로젝트를 수행하면서 얻은 이슈에 HPT(Human Performance Technology; 수행공학)를 적용하여 조직적인 차원에서 프로젝트 관리자의 육성 로드맵을 만들고 이를 확산시키는 활동을 진행하고 있다. 이에 본 발표에서는 HPT측면에서 컨버전스 프로젝트 이행역량을 강화하기 위한 사례를 소개하고자 한다.

본 연구에서는 u-Eco City 건설을 위한 u-City 기술 연구의 첫걸음으로서 기반시설 관점에서 u-City기술을 분류하고자 한다. 이는 u-City를 구현할 때 기반시설에 u-City기술을 접목함으로써 u-City서비스를 실현할 수 있기 때문에 의미가 있다. 즉, "유비쿼터스 도시건설 등에 관한 법률"에서 언급하고 있는 u-기반시설의 개념을 도입하여 기술을 분류함으로써 서비스-기술-기반시설의 연계성을 명확하게 파악할 수 있다. 본 연구에서 제시하고자하는 u-City 기술의 분류는 u-City기술의 범위를 정하고, 추후 기술개발의 전략적 목표 설정 및 기술전략 수립의 기초자료로써 활용될 수 있으리라 기대된다.

This paper addresses the task of transferring facial blendshape models to an arbitrary target face. Blendshape is a common method for the facial rig; however, production of blendshape rig is a time-consuming process in the current facial animation pipeline. We propose automatic blendshape facial rigging based on our blendshape transfer method. Our method computes the difference between source and target facial model and then transfers the source blendshape to the target face based on a deformation transfer algorithm. Our automatic method provides efficient production of a controllable digital human face; the results can be applied to various applications such as games, VR chating, and AI agent services.
