Smart Work is an extended version of telecommuting or distance work pursuing an objective of work-life balance which is one of the hottest issues in management research. With diffusion of Smart Work, a problem has been raised that Smart Work makes the boundary between work and non-work blur, and may break the balance of work-life. However, work-life balance will be achieved by actively managing the boundary between work and non-work rather than passively taking the consequences. In order to find out whether Smart work improves work-life balance, we need to understand the precedence factors influencing on job satisfaction and the role of boundary management strategy which Smart Workers actively choose. This paper considered the bi-directional permeability between work and non-work domain and developed a research model containing a causal relationship among three factors, job autonomy, job involvement, and job satisfaction, and the moderation effect of boundary management strategy. The results show that both job autonomy and job involvement affect job satisfaction and boundary management strategy which Smart Workers utilize plays a moderating role influencing on job satisfaction.

Electronic cleansing is an image post processing technique in which the tagged colonic content is subtracted from colon using CTC images. There are post processing artefacts, like: 1) soft tissue degradation; 2) incomplete cleansing; 3) misclassification of polyp due to pseudo enhanced voxels; and 4) pseudo soft tissue structures. The objective of the study was to subtract the tagged colonic content without losing the soft tissue structures. This paper proposes a novel adaptive method to solve the first three problems using a multi-step algorithm. It uses a new edge model-based method which involves colon segmentation, priori information of Hounsfield units (HU) of different colonic contents at specific tube voltages, subtracting the tagging materials, restoring the soft tissue structures based on selective HU, removing boundary between air-contrast, and applying a filter to clean minute particles due to improperly tagged endoluminal fluids which appear as noise. The main finding of the study was submerged soft tissue structures were absolutely preserved and the pseudo enhanced intensities were corrected without any artifact. The method was implemented with multithreading for parallel processing in a high performance computer. The technique was applied on a fecal tagged dataset (30 patients) where the tagging agent was not completely removed from colon. The results were then qualitatively validated by radiologists for any image processing artifacts.

Most current machine vision systems for industrial inspection were developed with one specific task in mind. Hence, these systems are inflexible in the sense that they cannot easily be adapted to other applications. In this paper, a general vision system framework has been developed that can be easily adapted to a variety of industrial web inspection problems. The objective of this system is to automatically locate and identify \\\"defects\\\" on the surface of the material being inspected. This framework is designed to be robust, to be flexible, and to be as computationally simple as possible. To assure robustness this framework employs a combined strategy of top-down and bottom-up control, hierarchical defect models, and uncertain reasoning methods. To make this framework flexible, a modular Blackboard framework is employed. To minimize computational complexity the system incorporates a simple multi-thresholding segmentation scheme, a fuzzy logic focus of attention mechanism for scene analysis operations, and a partitioning if knowledge that allows concurrent parallel processing during recognition.cognition.

The objective of this study were to identify the state of re. cognition and attitude of residents in Seoul city about air environment and to identify factors affecting attitude toward air environment. Study object was residents in Seoul city sampled by multistage random proportional sampling. Sample size was 0.0067%(500 persons) of total residents in Seoul city. The results were divided into two parts: (1) descriptive results of recognition and attitude toward air environment, (2) results of factor analysis to classify categories of attitudes toward air environment and regression analysis to identify factors affecting attitude toward air environment. Most of resident in Seoul city recognized that air environment in Seoul city was highly polluted and was not satisfactory. Experience of damage of air pollution was reported in about 70% of residents in Seoul city. More than 60% of residents in Seoul city had concern about air environment. Attitude toward air environment were classified into four categories using factor analysis: Necessity of intervention of local government for air environment conservation, Participation of residents and enterprises for air environment conservation, Optimistic attitude about air pollution, Preference of economy. Factors affecting the above attitudes were knowledge about air pollution, knowledge about policies and institutions related air environment conservation, concern about air environment, educational level, subjective assessment of air environment, sex, marital status. In conclusion this study suggested providing information of air environment in Seoul city to the residents and to educating residents for making positive attitude about air environment conservation.

Objective : To explore and describe coordinators' experiences in collaborative practices between the traditional Korean medicine doctors and the western medicine doctors. Methods : Five coordinators who agreed and completed the informed consent to take part in this qualitative study were interviewed thoroughly and tape-recorded. Transcribed data were analysed thematically with ground theory. Results : Most participants started their coordinating work without sufficient knowledge and systemic support. They, however, could find their identity as coordinators for collaborative practices through preparing manuals and protocols, providing comprehensive patients care, and experiencing the partnership with doctors. To coordinate Korean medicine and western medicine practices efficiently, participants have tried to enhance their professional knowledge and skills, and establish favorable networks. On the other hand, they were in dilemmas of being a multi-player and imbalance of responsibilities and powers in their jobs. Conclusions : It is recommended to clarify job description of coordinator for collaborative practices, develop training programme, and provide the institutional support for wider recognition of coordinator. Findings from this study should be considered in both Korean medicine-western medicine collaborative research and practice.

In clinical clerkships, residents function as trainees, workers, and teachers for other medical students. Although residents care for patients in harsh environments and encounter precarious patient-safety situations, they are working towards becoming competent specialists. Residency education programs are very important in cultivating specialists able to adapt to the rapidly-changing medical environment, and are also necessary to improve the quality of specialist training. Competent specialists not only need clinical competency, but also a wide range of abilities including professionalism, leadership, effective communication, cooperation, and attention to continuous professional development/continuing medical education activities. Each Korean association of specialties has its own educational goals and standardized education programs to help residents learn specific techniques and competencies related to medical care for patients, though the training environment of each residency is different within each trainee hospital. Although it is also important to evaluate residency education programs, currently there is only an examination of knowledge and assessment of skills based on mini-clinical evaluation exercises or direct observation of procedural skills. In order to develop an objective and estimable evaluation tool that can assess the overall achievement level within each training course, it is necessary to evaluate the knowledge, skills, and attitudes of residents. Residency education programs need further attention and reform.

We propose a knowledge-based algorithm for extracting an object boundary from low-quality image like the forward looking infrared image. With the multi-classes training data set, the global shape is modeled by multispace KL(MKL)[1] and curvature model. And the objective function for fitting the deformable boundary template represented by the shape model to true boundary in an input image is formulated by Bales rule. Simulation results show that our method has more accurateness in case of multi-classes training set and performs better in the sense of computation cost than point distribution model(PDM)[2]. It works well in distortion under the noise, pose variation and some kinds of occlusions.

The purpose of this research is to analyze what industry professionals and educators perceive as the definition of "research" and foodservice related-research so that the research become rather systematic and useful research. The research result is as follows. First, the independent t-test analysis of the definitions of research showed that the industry professionals were recognizing it as "investigations that are directed toward the discovery of new scientific knowledge that has specific commercial objectives with respect to products or processes or operation" while the educators were regarding it as "original investigation for the advancement of scientific knowledge that does not have a specific commercial objective." Second, the finding about the application of foodservice related-research to decision-making showed that the industry professionals did not fully utilize foodservice research and did not think it is applicable in the industry. That is because academic journal language is too hard for them to understand and they want to see research findings in industry shows and exhibitions or industry magazines in common understandable language. Lastly, foodservice researchers could initiate the dialog between themselves and industry professionals to diagnose the problems of the industry better and provide practical solutions through research findings.
