  • Chatbot is emerging as an important interface window for business. This change is due to the continued development of chatbot-related research from NLP to NLU and NLG. However, the reality is that the methodological study of drawing domain knowledge and developing it into a user-friendly interactive interface is weak in the process of developing chatbot. In this paper, in order to present the process criteria of chatbot development, we applied it to the actual project based on the methodology presented in the previous paper and improved the development methodology. In conclusion, the productivity of the test phase, which is the most important step, was improved by 33.3%, and the number of iterations was reduced to 37.5%. Based on these results, the "3 Phase and 17 Tasks Development Methodology" was presented, which is expected to dramatically improve the trial and error of the chatbot development.

  • The purpose of this study was to evaluate the effects and define the educational strategies of the cyber education offered to students for Bachelor of Science degree program(RN-BSN). The participants in this study were 67 students in two courses, Growth and Development, and Nursing Process. The main components of the cyber classes were the electronic board and on-line discussion board. The study was conducted from March 4, 2001 to July 23, 2001 at Y University in Seoul, Korea. To examine the effects of the cyber education, learning motivation, and learning satisfaction were measured by questionnaires to the students before the initial class and after completing the class. Learning achievement was measured by the grades for each course. The data were analyzed using frequencies, t-test, and paired t-test. The specific results of the course evaluation were compared and analysis was done to examine differences between traditional classroom teaching and cyber teaching. The study results are as follows: 1. There were no significant differences on total scores for learning motivation between pre-cyber education and post-cyber education. However, there were significant decreases in the post test compared to the pre test for the items, ' I'd like to get as high a score as possible compared to other students (t=-2.20, p=.03)' and ' I'm sure to acquire good grades(t=-5.22, p=.00) '. 2. The average score for learning satisfaction using cyber education was high at 3.52. 3. To define learning achievement using cyber education, grades for students taking cyber classes this year were compared to student grades for a class using traditional lassroom teaching last year. The score was significantly higher for classroom students in the 'Growth and Development' course (t=-3.5, p<.001), and the score was significantly higher for the cyber education students in the 'Nursing Process' course (t=4.3, p<.000). 4. The average of post scores on computer competency was significantly higher on six items, general knowledge about computers, data management and data research, ability to communicate using computer, and internet surfing. On the basis of the above findings, this study suggests that cyber education in nursing courses is effective and readily available. However, it is recommended that consideration be given to characteristics of the course when developing cyber education programs for nursing courses.

  • This study identified terminologies related to the proximity and frequency of disaster by social network analysis (SNA) and text mining, and then expressed the outcome into a mind map. The termdocument matrix of text mining was utilized for the terminology proximity analysis, and the SNA closeness centrality was calculated to organically express the relationship of the terminologies through a mind map. By analyzing terminology proximity and selecting disaster response-related terminologies, this study identified the closest field among all the disaster response fields to disaster response and the core terms in each disaster response field. This disaster response terminology analysis could be utilized in future core term-based terminology standardization, disaster-related knowledge accumulation and research, and application of various response scenario compositions, among others.

  • As the nature of triathlons is competition in three successive sports, triathletes experience elevated levels of stress on the body that are absent in single-sport athletic events, and consequently there are more potential medical problems to prepare for. Triathletes can also experience problems such as hypothermia, heat illness, excessive exposure to ultraviolet radiation, musculoskeletal injuries and trauma, immunosuppression, and haemolysis. Depending on the potentiality of such above-listed problems occurring in any given race, race organizers will prepare preventative measures and treatments accordingly. Olympic distance is not the only triathlon racing distance. Sprints, which are normally around half the Olympic distance, are common distances, as well as Long (2 km swim, 80 km bike, 20 km run), Ironman (3.8 km swim, 180 km bike, 42 km run), and ultra-distance events varying in length. Races of longer duration normally result in a higher percentage of athletes experiencing the above-mentioned medical problems, as well as inducing additional health risks such as hyponatraemia. Minimizing the occurrences of serious health issues is possible through the following means: carefully preparing for the probable race-day weather conditions; proper management and organization of the race; preparing an extensive water-safety and ground-course safety plan; distributing necessary nutrition along the course; and stressing the importance for athletes to have proper knowledge concerning race nutrition, biomechanical technique, physical preparation, and utilization of safe equipment. While risks of competing in triathlon are many, the instances of such medical problems are not excessive, and the triathlon has a reputation of being a reasonably safe sport as long as athletes with high risk take added precautions.

  • The war simulation systems in Republic of Korea Army have been getting more and more important because soldiers can effectively and efficiently learn and share their war-related knowledge based on the interactions through the systems. But, up to now, the access to the war simulation systems has been limited to only soldiers. So, little research on them has been conducted. This study explores the effects of the antecedents to the flow experience and the characteristics of the systems on soldiers' intentions to use them. Based on the 118 samples collected from officers in Republic of Korea Army, this study empirically shows the logical reality of the war simulation systems and the flow experience positively influence soldiers' intentions to use the systems and the clarified goals, feedbacks, and the levels of the missions in the systems are significant antecedents to the flow experience. Useful implications are presented and discussed based on the new findings.

  • It is important to understand the potential human health implications of exposure to environmental chemicals that may act as hormonally active agents. It is necessary to have an understanding of how pharmaceutical and personal care products and other chemicals affect the ecosystem of our planet as well as human health. Endocrine disruption is defined as the ability of a chemical contaminating the workplace or the environment to interfere with homeostasis, development, reproduction, and/or behavior in a living organism or it's offspring. Certain classes of environmentally persistent chemicals such as polychlorinated biphenyls (PCBs), dioxins, furans, and some pesticides can adversely effect the endocrine systems of aquatic life and terrestrial wildlife. Research continues to support the theory of endocrine disruption. However, endocrine disruption researches have been applied to proteomics poorly. Proteomics can be defined as the systematic analysis of proteins for their identity, quantity and function. It could increase the predictability of early drug development and identify non-invasive biomarkers of tonicity or efficacy. Proteome analysis is most commonly accomplished by the combination of two-dimensional gel electrophoresis (2D/E) and MALDI-TOF mass spectrometry (MS) sr protein chip array and SELDI-TOF MS. Proteomics have an opportunity to play an important role in resolving the question of what role endocrine disruptors play in initiating human disease. Proteomics can also play an imfortant role in the evaluation of the risk assessment and use of risk management and risk communication tools required to address public health concerns related to notions of endocrine disruptors. Understanding the need for the proteomics and possessing knowledge of the developing biomakers used to abbess endocrine activity potential will he essential components relevant to the topic of endocrine disruptors.

  • New product development(NPD) is imperative management activity for growth and survival of the firm. In the context of the small and medium-sized enterprises(SMEs), the firm became further dependent upon NPD with the increasing turbulence in environments. This research suggests the role of entrepreneurship orientation(EO) and absorptive capacity(ACAP) that affect the success rate of NPD in SMEs. Although each of them has been highlighted as critical resources in the aspect of the sustainable competitive advantage, the relationship and the effect between EO and ACAP have received scant attention. Based on the sample of 261 Korean SMEs, this study examines the direct/indirect effect of EO and ACAP on NPD performance. While innovativeness of EO has the direct effect on NPD performance, both risk-taking and proactiveness of EO show no significance. While realized ACAP has the positive influence on NPD performance, potential ACAP shows no significant influence. In addition, we found that the impact of innovativeness on NPD performance was being partially mediated by ACAP whereas the relationship between proactiveness and NPD performance being fully mediated by ACAP. These findings would provide generic insights that both exploration and exploitation regarding knowledge and resources in SMEs are necessary in order to increase NPD performance and two activities have to align with EO.

  • In order to promote national competition on knowledge based-society in 21centuries, it is important for us to train talented people who have much creativity. Comparing curriculums and contents studied in SECG (Science Education Center for the Gifted) and other organizations is object of this thesis. Finding implications of proper GATE(gifted and talented education) by understanding the present conditions is also a part of this thesis. We select 5 Science Education Centers for the Gifted and devise framework for analysis in order to analyze chemical textbooks in GATE programs. The framework consists of 6 categories including the contents, the level of activities, the opening extent of experiments, and the ability to think creatively. In our study of textbooks, we have found that the contents of chapters are divided properly but lacked the field of frontier and convergence science. Their activity types will have to develop programs which consist of various activities such as lectures and experiments. Precedent studies and study activities to promote scientific thinking were rated highly in general ratio. The level of studies that we analyzed lacked creative activities very much. In the opening extent of experiments, activities in the level 2 and the level 3 were low-rate. And in our study of thinking creatively, activities of promotion for expanded and related-ability to think seemed to lack. In order to achieve specific education for the gifted children, developments of GATE program is required. In the in-depth analysis from the questionnaires of Likert's method's descriptions, narrations, and interviews, it is divided into two answers in depth: contents of program, management of program. These also divided into two answers by attitude: positive answer or negative answer. According to the responses of the contents of program, the result of analysis shows that most respondents have positive reactions to not only contents and the managing method of SECG programs, but also to individual enhancing-abilities overall.

  • Owing to recent advanced techniques in information and communication technology(ICT), our daily life has been changing very quickly and our life style has also been affected greatly. In the current knowledge and information society, the disabled can have a right to enjoy benefits of advanced ICT technologies. However, there is a barrier called digital divide so that the disabled have some difficulties to communicate to the world with ICT technologies. In this sense, our job is to close digital divide and let the disabled enjoy benefits of ICT technologies. Recently there have been some research works to close digital divide between the disabled and the non-disabled. Among various attempts to close digital divide, improving web accessibility for the disabled is the biggest concern since web is a still representative tool among ICT tools. The purpose of this paper is to propose some practical guidelines for improving web accessibility for the disabled. The proposed improvement guidelines are developed based on the existing web accessibility guidelines and are upgraded for more adaptable to the disabled. Our principles are based on the following philosophy. First, any input transmission must be more confirmed. Second, prevent any instant request. Third, allow the disabled to record or store the contents if necessary. Fourth, reduce physical movement for the disabled. Fifth, provide more interaction tools for the disabled.
