  • In this paper, we proposed an algorithm for arrhythmia classification, which is associated with the reduction of feature dimensions by linear discriminant analysis (LDA) and a support vector machine (SVM) based classifier. Seventeen original input features were extracted from preprocessed signals by wavelet transform, and attempts were then made to reduce these to 4 features, the linear combination of original features, by LDA. The performance of the SVM classifier with reduced features by LDA showed higher than with that by principal component analysis (PCA) and even with original features. For a cross-validation procedure, this SVM classifier was compared with Multilayer Perceptrons (MLP) and Fuzzy Inference System (FIS) classifiers. When all classifiers used the same reduced features, the overall performance of the SVM classifier was comprehensively superior to all others. Especially, the accuracy of discrimination of normal sinus rhythm (NSR), arterial premature contraction (APC), supraventricular tachycardia (SVT), premature ventricular contraction (PVC), ventricular tachycardia (VT) and ventricular fibrillation (VF) were $99.307\%,\;99.274\%,\;99.854\%,\;98.344\%,\;99.441\%\;and\;99.883\%$, respectively. And, even with smaller learning data, the SVM classifier offered better performance than the MLP classifier.

  • The purpose of this study is to develop the KPIs(Key Performance Indices) needed to improve management and strategy in the dental clinic based on the four perspectives of BSC(Balanced Scorecard). The questionnaire was conducted on 52 dentists approved by Dental Managment Research Committee in Seoul National University as a panel. Using the Delphi technique, the top five KPIs for each point of perspective in BSC were extracted from KPI pools. In the third survey, the top five KPIs of all points were compared with each other through AHP(Analytic Hierarchy Process) method, and priority and overall importance rankings were calculated. The biggest difference in the three level AHP results was the customer perspective took priority to others. In the second survey, the financial perspective, which was number one, was pushed back. The overall significance of KPIs was in the order of customer, internal process, finance, learning and growth perspective, with the exception of medical profits (5th of 20) and new patient growth (10th of 20). We were able to overcome the limitations of the Delphi Technique with the AHP method. In general, the financial perspective in BSC is known to be the most important, but we conclude that the customer perspective is more important through the pairwise comparison survey. In the current dental service market, which is a long-term recession, excessive competition, customer satisfaction and customer relationship management seem to be the first goal to pursue in dental clinic.

  • Research and Development(R&D) was once considered to be a unique, creative and unstructured process that was difficult, if not impossible, to manage and control. R&D decisions impact the entire enterprise. Therefore, decisions must not be based solely on R&D's perception of what is important or worthwhile. R&D contributions are difficult to measure separately from other functional organizations such as manufacturing and marketing. While some firms are attempting to overcome perceived limitations in traditional accounting-based performance measures using ROI, EVA, others are embracing the use of non-financial measures for decision making and performance evaluation. In particular, many firms are implementing 'Balanced Scorecard(BSC)' systems that supplement traditional accounting measures with non-financial measures focused on at least three other perspectives-customers, internal business processes, and learning and growth. AHP is a popular multi-attribute decision making model that allows for the development of importance rankings. The AHP has been applied in a wide variety of practical settings to model complex decision problems. The former, determine Perspectives and the Key Performance indicator(KPI) through the former research, the latter compose the questionnaire for determine the weight of perspectives and KPIs. And then, make a survey with researchers about 4 perspectives and 18 KPIs. The results will be simulate with Expert Choice 2000 for determine the weights. This results helps establish the firm's business strategy and technology strategy The firm should establish the business strategy to consider market position, business growth potential, and technological capabilities.

  • Purpose: This study aimed to identify the relationship among knowledge, attitudes and prevention behaviors (PB) on tuberculosis (Tb) infection in nursing students. Methods: 268 subjects were recruited from two universities located in C D cities of Korea and data were collected utilizing self-reported questionnaires. Results: The mean scores of knowledge, attitudes and PB on Tb infection were 64.83, 3.18 and 2.97. The knowledge differed according to gender (t=-3.16, p=.002), grades (F=32.19, p<.001), educational experience about Tb (EETb) (F=10.59, p<.001), learning information about Tb (t=3.08, p=.002) and getting Tb: self or others (t=2.78, p=.006). The attitudes differed according to grades (F=7.71, p<.001) and EETb (F=2.68, p=.047). The PB differed according to grades (F=7.02, p<.001) and EETb (F=4.55, p=.004). Significant correlations were found between knowledge and PB (r=.20, p=001), attitudes and PB (r=.33, p<.001). The most significant factor influencing PB was attitudes with R2 value of 13.9% (F=11.81, p<.001). Conclusion: These findings indicate that knowledge and attitude adjustment may be necessary to improve PB for Tb infection in nursing students. Moreover further study is necessary to find out the ways to reinforce the level of attitudes. The results of the study can be utilized in educational programs for preventing Tb infection in nursing students.

Through this study, we assumed that it will be used basis data on further Korean Yaksun research. Method : We conducted survey targeting for 26 Yaksun restaurants and Temple food restaurants serving Yaksun cuisine(medicinal food) menu from July 2012 to January 2013. The questionnaire was composed of several parts including the kinds of medicinal herbs that was used in Yaksun, medicinal food types that use a lot of medicinal herbs, medicinal herbs criteria used in the selection of medicinal food, and education experience learning Yaksun cuisine. Results : Only 11 restaurants answered the questionnaire among the targeting restaurants of survey objects. The number of Herbs was investigated in each restaurant was maximum 65 kinds and minimum 7 kinds (average 32 kinds). All restaurants used Angelicae Gigantis Radix in their restaurant. And Nelumbinis Semen, Zingiberis Rhizoma, Glycyrrhizae Radix, Acanthopanacis Cortex, and Gardeniae Fructus are well used medicinal herbs in Yaksun. Types of medicinal food using a lot of herbs were rices porridges rice cakes, both vegetables salads and stews soups. Almost chefs or restaurant's representatives learned cooking medicinal food at temples, food research centers, university attached institutions, and cooking schools. Conclusion : Medicinal herbs used in Yaksun restaurants are familiar with Korean and easily available. These herbs has better efficacy, taste, scent, color in comparison of the others. For the development of Korean Yaksun, further research of divers parts in Yaksun materials should be conducted.

  • The Republic of Korea has made major strides in Information and Communication Technology (ICT) over the last five decades. After going through continuous efforts in e-Government and national informatization, Korea has become one of the global E-government leaders. Korea's E-government Development Index ranking assessed by the United Nations improved from 15th in 2001 to the top in 2010 and 2012 out of 192 countries worldwide, and its E-participation Index ranking was also ranked 1st in 2010& 2012. In addition, many of Korea's E-government practices until now have been introduced to the world as the best cases and received worldwide acknowledgement. The importance of official development aid/assistance (ODA) through informatization is especially gaining attention as Korea has joined the OECD Development Assistance Committee (DAC) and its status has significantly improved within international organizations. The Korean government has selected countries that have high potential in trade, economic, and E-government cooperation or those that are selected as ODA priority countries by the international community and has carried out various activities including ICT consultation, ICT Cooperation Center operation, and ICT learning programs. With joining the OECD DAC, Korea's overseas aid projects are expected to increase and be carried out in a more systematic manner. Also in the area of informatization, the importance of not only the overseas aid 'in ICT' itself but also the overseas aid 'through ICT' is increasing along with the expanding scale for more efficient and influential support. The Korean government's comprehensive reach of international projects in the ICT arena, aims to foster the global partnership for development by sharing and expanding the benefits of ICTs. The Korean government recognizes its advances and has endeavored to share them with others through participation in international forums and hosting of workshops.

  • Cycling that transform human energy into mechanical energy is one of the man-machine systems out of sports fields. Benchmarking means "improving ourselves by learning from others', therefore benchmarking toward dominant cyclist is necessary on field. The goals of this study were to provide important factors on multi-disciplines (kinematics, physiology, power, psychology) for a tailored-training program that is suitable to individual characteristics. Two cyclists participated in this study and gave consent to the experimental procedure. One was dominant cyclist (years: 21 yrs, height: 177 cm, mass: 70 kg), and the other was non-dominant cyclist (years: 21, height: 176, mass: 70). Kinematic data were recorded using six infrared cameras (240Hz) and QTM (software). Physiological data (VO2max, AT) were acquired according to graded exercising test with cycle ergometer and power with Wingate test used by Bar-Or et. al (1977) and to evaluate muscle function with Cybex. Psychological data were collected with competitive state anxiety inventory (CSAI-2) that was devised by Martens et. al (1990) and athletes' self-management questionnaire (ASMQ) of Huh (2003). It appears that the dominant's CV of ankle joint angle was higher than non-dominant's CV and dominant's pedaling pattern was consistent in biomechanics domain, which the dominant's values for all factors ware higher than non-dominant's values in physical, and physiological domain, and their values between cognitive anxiety and somatic anxiety were contrary to each other in psychology. Further research on multi-disciplines may lead to the development of tailored-optimal training programs applicable with key factors to enhance athletic performance by means of research including athlete, coach and parents.

  • This study conducted a survey on recognition of teachers, students, and Parent Teacher Association(PTA) for the Education for Sustainable Development from April to October, 2008. It confirmed a couple of facts, which were summarized as follows; First, among eight educational areas including Environmental Education, Energy Education, Gender Education, World Heritage Education, Multi-cultural Coexistence Education, Peace Education, Education for human rights, and Education for international understanding that UNESCO had offered, this study showed that the 'Environmental Education' is a relatively important area comparing with others. Second, 54.4% of the respondents have agree with the need of the education for sustainable development in the middle school and the high school, and 54.1% of them showed their willingness to participate in the program. Third, because 49.2% of the respondents chose 'important' on the question of 'how important the field education and the experience education are', it looked like most of them agreed with the importance of the field education and the experience education. Fourth, because 61.1% of the responded teachers chose 'need' on the question of 'if it needs relationship with other studies', it looked like most of them agreed with the necessity of relationship with other studies. Fifth, 62.5% of the respondents chose 'no' on the question of 'if they conduct the education for sustainable development Even if some wanted the education for sustainable development, most of them would not do it in the regular curriculum, but in the special activity class or teacher's discretional time. Sixth, most respondents indicated the teacher's class burden and the teacher's lack of knowledge as the problem if the education for sustainable development would be conducted. This result implied that in order to vitalize the education for sustainable development, the teacher's class burden should be reduced and the teacher train program is necessary. Finally, urgent requested studies could improve the education for sustainable development in communities and schools, because the result of the survey showed education, natural observation learning, and visiting ecological parks as important elements.
