The novel network architecture is recently required to accommodate a variety and intelligence of communication services. It is also required to provide customized network functions and to efficiently satisfy a various user's requirements. Accordingly, open network architecture based on ATM transport network features has been mainly studied in communication network. This paper evaluates the VSN(Virtual Switch Network) characteristics in the call processing of IMT-2000 switching system, which is composed of VSN instead of ATM switch network. VSN means switch network which is composed of ATM transport network. As a result, this paper proposes new VSN based ATM-MSC architecture with integrated call and connection control systems. and evaluates call processing delay characteristics using call process procedures. Internal call processing delay is increased approximately 3.5msec than the conventional ATM switching system. The experimental values applied in the analysis condition are the load 0.8, and the 100km distance between CCCPs(Call and Connection Control Processors) and VSNs. It is confirmed that the VSN has the potentiality in the practical implementation.

Recently, WBI model which is based on web has been proposed in the part of the new activity model of teaching-learning. The demand for the customized coursewares which is required from the learners is increased, the needs of the efficient and automated education agents in the web-based instruction are recognized. But many education systems that had been studied recently did not service fluently the courses which learners had been wanting and could not provide the way for the learners to study the learning weakness which is observed in the continuous feedback of the course. In this paper we propose design of multi-agent system for course scheduling of learner-oriented using weakness analysis algorithm. First, proposed system monitors learner's behaviors constantly, evaluates them, and calculates his accomplishment. From this accomplishment, the multi-agent schedules the suitable course for the learner. The learner achieves an active and complete learning from the repeated and suitable course.

Objective: This study intended to analyze parenting characteristics, difficulties and support needs of multi-cultural families that had children under 3 years old, in order to develop their supporting resources. Methods: This study performed semi-structured interviews with 7 mothers from multi-cultural families that had their young children enrolled at child care and education centers in Gyeonggi Do. The interview data transcribed were analyzed using the successive contents analysis, and led to 4 themes and 12 sub-themes. Results: First, the mothers from multi-cultural families were married without understanding the Korean language and culture. Second, the multi-cultural mothers didn't properly respond to their children's needs in interaction and language aspects. As a result, the multi-cultural support centers and child care and education centers gave help to them. Third, in the view of the difficulties facing mothers, parenting problems caused by the lack of information concerning child education, the biased burden of parenting, and the different parenting values of Korean families were all expressed by the mothers. Fourth, regarding support needs, providing individual professional support for children and child-raising support for mothers, customized language and employment support for mothers and parenting education for fathers and family education on multi-culturalism are needed. Conclusion/Implications: Suggestions for decreasing the difficulties facing multi-cultural families that had children under 3 years old were discussed.

A Word is the smallest unit for text analysis, and the premise behind most text-mining algorithms is that the words in given documents can be perfectly recognized. However, the newly coined words, spelling and spacing errors, and domain adaptation problems make it difficult to recognize words correctly. To make matters worse, obtaining a sufficient amount of training data that can be used in any situation is not only unrealistic but also inefficient. Therefore, an automatical word extraction method which does not require a training process is desperately needed. WordRank, the most widely used unsupervised word extraction algorithm for Chinese and Japanese, shows a poor word extraction performance in Korean due to different language structures. In this paper, we first discuss why WordRank has a poor performance in Korean, and propose a customized WordRank algorithm for Korean, named KR-WordRank, by considering its linguistic characteristics and by improving the robustness to noise in text documents. Experiment results show that the performance of KR-WordRank is significantly better than that of the original WordRank in Korean. In addition, it is found that not only can our proposed algorithm extract proper words but also identify candidate keywords for an effective document summarization.

According to increasing SNS users and developing smart devices like smart phone and tablet PC recently, many techniques to classify user emotions with social network information are researching briskly. The use emotion classification stands for distinguishing its emotion with text and images listed on his/her SNS. This paper suggests a method to classify user emotions through sampling a value of a representative figure on a trigonometrical function, a representative adjective on text, and a canny algorithm on images. The sampling representative adjective on text is selected as one of high frequency in the samplings and measured values of positive-negative by SentiWordNet. Figures sampled on images are selected as the representative in figures; triangle, quadrangle, and circle as well as classified user emotions by measuring pleasure-unpleased values as a type of figures and inclines. Finally, this is re-defined as x-y graph that represents pleasure-unpleased and positive-negative values with wheel of emotions by Plutchik. Also, we are anticipating for applying user-customized service through classifying user emotions on wheel of emotions by Plutchik that is redefined the representative adjectives and figures.

Background: The global population is aging rapidly, and accordingly, the number of patients with dementia is increasing every year. Although the need for dental treatment increases for various reasons in patients with dementia, they cannot cooperate during dental treatment. Therefore, behavioral management, including sedation (SED) or general anesthesia (GA), is required for patients with dementia. Thus, this study aimed to investigate the trends and effects of SED or GA in patients with dementia undergoing dental treatment in South Korea based on the Korean National Health Insurance claims data. Methods: This study utilized customized health information data provided by the Health Insurance Review and Assessment Service. Among patients with records of using sedative drugs during dental treatment from January 2007 to September 2019, patients with the International Classification of Diseases-10 code for dementia (F00, F01, F02, F03, and G30) were selected. We then analyzed the full insurance claims data for dental care. Age, sex, sedative use, and dental treatment of patients were analyzed yearly. In addition, the number of cases of GA or SED per year was analyzed, and changes in behavioral management methods with increasing age were investigated. Results: Between January 2007 and September 2019, a total of 4,383 (male, 1,454; female, 2,929) patients with dementia received dental treatment under SED or GA. The total number of SED and GA cases were 1,515 (male, 528 ; female, 987 ) and 3,396 (male, 1,119 ; female, 2,277) cases, respectively. The total number of cases of dental treatment for 4,383 patients with dementia was 153,051 cases, of which 2.22% were under GA and 0.98% were under SED. Midazolam was the most commonly used drug for SED. Conclusion: Although gingivitis and pulpitis were the most common reasons for patients with dementia to visit the dentist, GA or SED for patients with dementia was frequently used in oral and maxillofacial or periodontal surgery.

This research explains a new process in architecture frameworks. A complete analysis on implementation of the specific frameworks can be conducted by a special system. Moreover, the system can be installed anywhere, and it produces a unique result, which is customized based on the contents of architectural designs by users. Before using the system, an architect should think about the design and the process of constructing frameworks because a computer sometimes computes misleading results although the architect describes architectural structures, which the designer wants. If the architect inputs the same process into the computer, and the result of frameworks changes, it is not a proper architectural design. Hence, a tool, which precisely treats data, is needed. Therefore, when constructing the proper architecture, a new paradigm of architecture should be used to distinguish the issues of discussion by using various data. Also, based on this information, an apartment housing complex design, related to possible parameters, which can be expressed by combining various fusion tables and geocloud, and architectural designs, is proposed.

Training, unlike education in holistic perspective, not only affects individual's potential of work competencies such as knowledge and technology, but also affects the job performance in organizational perspective. The effectiveness of training for civil servants who participated in mock jury trial learning of Suwon-si was verified using CIPP model. Participants valued the significance of the process of training rather than the conclusion that draws a certain solution, and based on the comparison and analysis of pre·post evaluations, the educational effect of mock trial training and its utilization at work in the future was higher than before the training, proving its effectiveness. In terms of the implications of training programs in addition to the program planner's evaluation, participant constitution in consideration of sex or employment period is needed for learning interaction among various learners, and information acquisition training on various local issues and conflict situations, as well as the combination of deliberation learning, are needed. in addition, it may be supplemented through customized conflict management raining related to pending projects for the effectiveness of training.

The purpose of this study is to analyze that ICT-based primary health care affects clinical changes of participants in the primary care chronic disease management pilot project using ICT medical care. Customized health information data, provided by National Health Insurance Service, was used for the analysis. The study targeted a total of 676 people that participated in primary care chronic disease management pilot project using ICT medical care from 2017 to 2018. Hierarchical regression was used to test three model. First, there were many subjects who used face-to-face consultation and non-face-to-face consultation(messaging), but less than half of patients using non-face-to-face consultation(telephone). Second, after participating in the pilot project, the fasting blood sugar level decreased. Third, the clinical condition of the subjects appeared to be an important factor in controlling blood sugar levels. Finally, patients using the non-face-to-face consultation(messaging) had reduced blood sugar levels after participating in the project. This results imply that non-face-to-face consultation is effective in reducing fasting blood sugar level with hospital intervention, and there are effects of the primary care chronic disease management project using ICT.
