This study has surveyed 379 social workers to recognize how much they believe their behaviors are ethical related to dual relationship and how many they have experienced dual relationships with their clients. In addition, we also examined if there were significant differences in social workers' beliefs and experiences according to their socio-demographic characteristics and organizational properties. To accomplish this purpose, we conducted frequency analysis, single sample t-test and one-way analysis of variance focusing on sexual, bartering and private relationships. Respondents tend to have a little permissive attitude about dual relationships while they little experienced of them. Social workers's beliefs and experiences are different depending on gender, education level, work experience, position, training experience of ethics and service target. From these results, it suggested that code of ethics for social workers and the curriculum of social work ethics should be revised reflecting on present field situation and inspiring ethical sensitivity.

LVC(live-virtual-constructive) integrated training system is a representative cyber-physical system. Each systems in a LVC system has different time domain, resolution and operation methods. So, it is very important to integrate different middlewares as a common middleware for heterogeneous systems using inter-working GWs. Especially, since the LVC system uses different time, it is necessary to study the method for guaranteeing causality and time synchronization among the events from different systems. In this study, we propose an time synchronization scheme to integrate the virtual and constructive system which use the simulation time of HLA (High Level Architecture)/ RTI (Run Time Infrastructure) into the live system based on the OMG DDS (Data Distribution Service). We propose a precise time synchronization scheme based on HLA time management and clock federate between participants and federates which are the communication objects of DDS and HLA/RTI respectively. In addition, we verified that time is well-synchronized among heterogeneous systems using the suggested scheme by implementing and demonstrating simulation applications on each middleware.

Objectives: The purpose of this study is to provide comprehensive information of qualification systems of developed countries needed to establish our national system for QI(Quality improvement) specialists. Methods: All articles related to any applicable domestic or foreign countries' laws, operational status, and detailed programs for professional qualification system of QI were reviewed. Result: In the United States, a non-profit organization, Healthcare Quality Certification Commission (HQCC) has set the policies, procedures and standards in the field of health care quality. And qualification system of CPHQ (certified professional in healthcare quality) has been operated in order to authenticate the qualifications in the field of quality management. IBQH(international Board for quality in healthcare), a qualification system of experts in the United Kingdom, was designed to assist the qualification of professionals to improve the quality of healthcare. In addition, Health Research Center of Feinberg School of Medicine in Northwestern University has been operating Master's and doctoral degree programs in the field of the quality of care and patient safety and IHI (institute for healthcare improvement) open school was operating a professional training course related to the quality of care and patient safety. Conclusion: Quantity and complexity of information of the quality of care and patient safety have been increased. For reform of the health care system, a special training course of the expertise and leadership are needed. So far, there is no national professional certification courses in our nation. Therefore essential job skill should be acquired individually. For systematic and effective quality improvement activities, the educational and certification system with professional development model are needed.

The purpose of this study is to propose the factors affecting collaboration between community nurses and social workers in Korea. Data that is used in this study, were collected from 295 provider respondents by questionnaire, additionally from telephone survey and secondary data review. This study focuses on the working relationship between professionals in the field of health and social care. Based on the literature review, this study proposes a conceptual framework for collaboration between nurses and social workers in community health and social care. The dependent variable in this study is collaboration. It reveals whether or not the inter-professional works and shows the level of collaboration. The independent variables are categorized in: the client characteristics (frailty of client, client-provider relationship); the provider characteristics (specialization, perception of interdependence, perception of the other professional); the organization characteristics (closeness of the other professional, autonomy, on-the-job training, evaluation-reward); and the community characteristics (urbanization, capacity of resources). Major findings are as follows: First, the factors that appear to have the strongest impact on whether or not inter-professional working of respondent sampled are: the perception of other professional; the perception of interdependence; closeness of, the, other professional; and the frailty of client. Secondly, the factors that found to have the most significant effect on level of cooperation are: the perception of, the other professional; on-the-job training; evaluation-reward; and the closeness of the other professional.

National Competency Standards (NCS) is a good resource for curriculum development and operations corresponding to the industrial damand. Recently, four-year colleges and universities are committed to a restructuring of the industry demand-driven training courses in order to strengthen competitiveness. However, NCS is focused to train the technical personnel in vocational training institutions(ex. College, Polytechnic University). Accordingly, NCS applications of four-year colleges and universities are hard to find. In this study, we propose a new model for NCS-based curriculum development and operations. Also, NCS was utilized to complement the existing curriculum. This paper includes the following contents; 1) NCS-based curriculum development process, 2) NCS-based course development and operation, 3) learner satisfaction analysis. Finally, this study provide practical implications to four-year colleges and universities to consider NCS application.

The recent interest in artificial intelligence and machine learning has partly contributed to an interest in the use of such approaches for hyperspectral remote sensing (HRS) imagery classification, as evidenced by the increasing number of deep framework with deep convolutional neural networks (CNN) structures proposed in the literature. In these approaches, the assumption of obtaining high quality deep features by using CNN is not always easy and efficient because of the complex data distribution and the limited sample size. In this paper, conventional handcrafted learning-based multi features based on expert knowledge are introduced as the input of a special designed CNN to improve the pixel description and classification performance of HRS imagery. The introduction of these handcrafted features can reduce the complexity of the original HRS data and reduce the sample requirements by eliminating redundant information and improving the starting point of deep feature training. It also provides some concise and effective features that are not readily available from direct training with CNN. Evaluations using three public HRS datasets demonstrate the utility of our proposed method in HRS classification.

With the development of online services, the ripple effect of negative comments is increasing, and the damage of cyber violence is rising. Various methods such as filtering based on forbidden words and reporting systems prevent this, but it is challenging to eradicate negative comments. Therefore, this study aimed to increase the accuracy of the classification of negative comments using deep learning and blur the parts corresponding to profanity. Two different conditional training helped decide the number of deep learning layers and filters. The accuracy of 88% confirmed with 90% of the dataset for training and 10% for tests. In addition, Grad-CAM enabled us to find and blur the location of swear words in negative comments. Although the accuracy of classifying comments based on simple forbidden words was 56%, it was found that blurring negative comments through the deep learning model was more effective.

This study was conducted with the aim of constructing a unified model according to the structure of qualification types of lifelong education professionals for the disabled. The research method consisted of procedures in which literature analysis and expert meetings were constructed in connection with each other. The contents of the study were suggested from the classification of qualification types into professional teacher type and coordinator type by focusing on special education and rehabilitation, which are related convergence fields that affect the qualification training of lifelong education professionals for the disabled. The two convergence fields, such as special education and rehabilitation welfare, lead to a separate application base from the perspective of education and welfare for the qualification of lifelong education professionals for the disabled, and finally confusion and conflict in the nature and contents of the curriculum and related services. A dichotomy structure system in which this phenomenon results in a divided type of qualification training for lifelong education professionals with disabilities was composed of several samples. In this regard, the curriculum and related services that can build convergence fields related to lifelong education for the disabled were reflected in the context of priority through the criteria that should be emphasized from the standpoint of the disabled in the overall category of establishing lifelong education support system for the disabled. In addition, by forming four qualification criteria centering on this, the common convergence field was composed of special education, thereby enhancing the aspect of inclusion in the rehabilitation welfare field and specific convergence into lifelong education for the disabled. As a result, the two qualification types were unified.
