School nurses can play an important role in improving the prognosis of traumatized teeth of school children when they are informed about the immediate and proper dental first aid steps. The purpose of this study were to assess the awareness of school nurses concerning the management of traumatized teeth and to determine if a lecture on dental trauma management could improve school nurses'knowledge on this topic. School nurses in Gwangju and Jeonnam province completed a questionnaire before and after the lecture on the first-aid knowledge with particular focus on the following three categories. Questionnaires are composed of questions asking general information and about knowledge and proper attitude in case of the specific situation on dental trauma. According to previous studies, school nurses' knowledge tended to be higher compared with the teachers. Improvement of knowledge in school nurse was observed in emergency actions, in visiting time, replantation, carriage method, vaccine prescription related with luxation, and in possibility of fragment reattachment related with subluxation and fracture. In conclusion, it is recommended that periodical education are needed for improvement of school nurses'knowledge on proper management of dental trauma emergency.

The purpose of this study is to analyze secondary science teachers' planning process for an integrated science lesson. For this study, relevant references were collected from various sources, including literatures, previous studies regarding integrated science education, and individual studies. Two teachers (one from middle school and the other from high school) participated and 'the five-step instructional design' was adopted from former studies in this subject. The teachers were asked to develop an instructional plan based on 'the design' provided. While the consultation provided a framework for an instructional plan, the teachers were asked to take a leading role in terms of selecting the chapter to be taught; analyzing the course structure; and making detailed teaching plans. In the course of consultations, discussions, records, and analysis were organized into a journal. Based on the journal, the aspects of the planning process, including difficulties and problems faced by teachers, were analyzed in-depth. From the study, it could be observed that both high school and middle school teachers face various difficulties in preparing for the integrated science lesson. Among other things, the teachers emphasized the difficulties in the stages of selecting the topic, collecting the relevant information, and restructuring and organizing the lecture contents.

The purpose of this study was to explore the direction of application and quality management plan of science curriculum of elementary and middle school according to the 2009 revised curriculum. In order to do this, nationwide survey was administered. The subject was 126 elementary school teachers and 88 middle school science teachers. It was founded that teachers had negative opinion on the introduction of the grade cluster system. They considered that it was appropriate to link the contents of Science subject with Practical Arts(Technology Home Economics) subject by similar topic. Science classes were implemented without changing the number of class hours in most schools. They recognized the necessity of differentiated instruction in science classes, but they seldom applied the differentiated instruction. And they suggested that the teaching-learning materials, evaluation materials and contents be provided to apply the STEAM. This study designates the following strategic supports for the effective implementation of 2009 revised science curriculum; 1) the science teachers training program to provide useful information for understanding and teaching the 2009 revised science curriculum, 2) the teachers' community in the school, 3) the development and provision of the feasible STEAM plans.

The purpose of this study was to develop concrete and in-depth knowledge about menarche and to raise the need of menstrual education. The data were collected from purposively sample 34 women from twenties to forties from April 27 to October 10, 1994. Semi-structured intensive interviews were done and these qualitative data were analysed with "Ethnograph" computer program. The results of the study were as follows : 1. The experience of menarche could be classified into two main groups, which were positive and negative response to menarche. The negative experiences were to be shameful, tearful, scared of the phenomena and thought as a kind of punishment for guilt or confused menarche with other symptoms of diseases. On the contrary, the positive experiences were to be proud of physical maturity and to think that is was wonderful, miraculous and to perceive it as a warm experience. 2. The experience of menarche was influenced by various factors. They were the knowledge about menstruation, the quality and amount of informations, the time of menarche, the environmental factors, the response of significant others toward menarche. The experience of menarche could be positive or negative according to these factors. 3. The previous information sources about menstruation could be significant others, school education and mass-media. The significant others were mothers, sisters, friends and the person in charge of school sex education such as school nurses, home economics, military drill and athletics of teachers. And mass-media included sex education booklets, nursery tales, TV programs, and publicity activities of sanitary napkin companies. 4. The opinions of the subjects about the proper time of menarcheal education could be grossly classified into two groups. The first was active approach toward children when they were in elementary school. The second was passive approach which postponed the time until the child ask about it, because it would be awkward for them to discuss about the topic. 5. The participants thought that the ideal methods of menarche education would be systematic school education programs, open discussion with daughters, audio-visual teachings, or practical education in everyday life. 6. The contents of the menarche education based on the participants' opinions, would be positive details about meanings and functions of menstruation. And it would be desirable if the attitudes of the person in charge of education could be positive, open-hearted, and favorable toward menstruation.

According to the recent development of measurement system utilizing one or a set of boreholes, visualization of the explored underground became to be a major issue. It induced even the introduction of monitoring apparatuses on the borehole wall with multi-function tool, but the usage of these was often limited by where is unfavorable rock condition and a few of engineers can approach. And so, a portable type of borehole camera with only the essential function has been investigated and a few of commercial models about this is recently being applied into the field condition. This paper was based on the monitoring results obtained using a commercial model by Dr. Nakagawa. Discontinuities in rock mass were the topic for the visualization, and it was studied how can visualize their three dimensional distribution and what a numerical formulation is needed and how to understand the visualization result. The numerical formulation was based on the geometric correlation between the dip direction / dip of discontinuous plane and the trend / plunge of borehole, a set of the equation of a plane was induced. As field application of this into two places, it is found that the above visualization methodology will be especially an useful geotechlical tool for analyzing the local distribution of discontinuities.

Fault localization plays a significant role in enormous distributed system because it can identify root cause of observed faults automatically, supporting self-managing which remains an open topic in managing and controlling complex distributed systems to improve system reliability. Although many Artificial Intelligent techniques have been introduced in support of fault localization in recent research especially in increasing complex ubiquitous environment, the provided functions such as diagnosis and prediction are limited. In this paper, we propose fault localization for self-managing in performance evaluation in order to improve system reliability via learning and analyzing real-time streams of system performance events. We use probabilistic reasoning functions based on the basic Bayes' rule to provide effective mechanism for managing and evaluating system performance parameters automatically, and hence the system reliability is improved. Moreover, due to large number of considered factors in diverse and complex fault reasoning domains, we develop an efficient method which extracts relevant parameters having high relationships with observing problems and ranks them orderly. The selected node ordering lists will be used in network modeling, and hence improving learning efficiency. Using the approach enables us to diagnose the most probable causal factor with responsibility for the underlying performance problems and predict system situation to avoid potential abnormities via posting treatments or pretreatments respectively. The experimental application of system performance analysis by using the proposed approach and various estimations on efficiency and accuracy show that the availability of the proposed approach in performance evaluation domain is optimistic.

Human emotion recognition is a research topic that is receiving continuous attention in computer vision and artificial intelligence domains. This paper proposes a method for classifying human emotions through multiple neural networks based on multi-modal signals which consist of image, landmark, and audio in a wild environment. The proposed method has the following features. First, the learning performance of the image-based network is greatly improved by employing both multi-task learning and semi-supervised learning using the spatio-temporal characteristic of videos. Second, a model for converting 1-dimensional (1D) landmark information of face into two-dimensional (2D) images, is newly proposed, and a CNN-LSTM network based on the model is proposed for better emotion recognition. Third, based on an observation that audio signals are often very effective for specific emotions, we propose an audio deep learning mechanism robust to the specific emotions. Finally, so-called emotion adaptive fusion is applied to enable synergy of multiple networks. The proposed network improves emotion classification performance by appropriately integrating existing supervised learning and semi-supervised learning networks. In the fifth attempt on the given test set in the EmotiW2017 challenge, the proposed method achieved a classification accuracy of 57.12%.

Background : Traditional Korean medicine(TKM) has gained in popularity among chronic patients in recent years. The use of TKM among patients with chronic diseases is common, with about two thirds of patients using some form of TKM in Korea. Objectives : The purpose of this study is to analyze the use of TKM and determine what factors affect to use TKM among patients with chronic diseases. The study also aims to provide information on TKM therapies and assist therapy selection among various TKM therapies for patients with chronic diseases. Methods : The design of the study was descriptive cross-sectional, and data were collected using a 21-item questionnaire. This study was conducted with subjects with confirmed diagnosis of chronic diseases, who live in Jeju Province, Korea. Results : Among the participants, past or current TKM use was 66.7%, with a statistically significant difference in gender and level of health status groups(p<0.05), but no difference in age, marital status, education, occupation, and income groups. The most common therapies of TKM used by the patients included acupuncture(51.1%), physiotherapy(16.8%), cupping(13.5%), and herbal medicine(4.8%). The main benefits from TKM perceived by the patients were chronic diseases management and health promotion. In a logistic regression analysis, significant influencing factors related to TKM use were gender, family income level, the extent of recognition of efficacy, heath status, and health security program. Conclusions : In this study the socio-demographic and health status, recognition of TKM efficacy factors associated with TKM use among patients with chronic diseases were similar to those found in the general population. The findings suggest that due to the relatively high use of TKM among patients with chronic diseases in Korea, this topic should be taken into account in the development of a holistic approach for patients with chronic diseases and an efficient chronic disease management system. Additionally proactive and consistent management of TKM is necessary in the health care system in Korea.

Online discussion bulletin in Korea is not only a specific place where user exchange opinions but also a public sphere through which users discuss and form public opinion. Sometimes, there is a heated debate on a topic and any article becomes a political or sociological issue. In this paper, we propose how to analyze the popularity of articles by collecting the information of articles obtained from two well-known discussion forums such as AGORA and SEOPRISE. And we propose a prediction model for the article popularity by applying the characteristics of subject articles. Our experiment shown that the popularity of 87.52% articles have been saturated within a day after the submission in AGORA, but the popularity of 39% articles is growing after 4 days passed in SEOPRISE. And we observed that there is a low correlation between the period of popularity and the hit count. The steady increase of the hit count of an article does not necessarily imply the final hit count of the article at the saturation point is so high. In this paper, we newly propose a new prediction model called 'baseline'. We evaluated the predictability for popular articles using three models (SVM, similar matching and baseline). Through the results of performance evaluation, we observed that SVM model is the best in F-measure and precision, but baseline is the best in running time.
