Environmental data plays an important role to enhance the reliability of experimental results in M&S(Modeling and Simulation). Especially in Military M&S, extreme weather events can be used for virtual training and simulation importantly. However, the environmental data is huge and it is dispersed among multiple organizations. It is difficult for M&S operators to select the date and area where the weather phenomenon occurs in the real environmental data and to acquire them. Environmental data retrieval technology based on Fuzzy criteria is one of the important technologies for developing Environmental Scenario Generator. As a result of this study, a fuzzy retrieval algorithm composed of four main parameters(RV, MF, FRA, and MRV) was presented. This study suggests that the RV can be used as 14 m/s for wind speed and 80 mm/d for precipitation to search the date of storm accompanied by high wind. The MF, the FRA, and MRV can be used sigmoid, 0.2, and 1 respectively. The algorithm proposed in this study is expected to be very useful for searching the date on which weather phenomena necessary for simulation occurred.

This study investigated how learning motivation affects satisfaction with training and employment services and its performance for participants in government-supported job skill development program of the clothing industry so as to provide fundamental data for developing a training program that fosters professionals and relieves the labor shortage in the clothing industry. 180 copies of questionnaires were statistically analyzed by SPSSWIN 21.0. Most trainees were low-income citizens in their 40s and 50s. They were divided into highly educated or low-educated. The results of the research are as follows: when the trainees were motivated by the goals of getting a certificate or a job, employment service satisfaction levels were influenced meaningfully. Secondly, educational satisfaction levels and occupational ability development also scored highly. Therefore, it is important to strengthen instructors' competency. Instructors must be required to have onsite experience so that they can provide authentic education that can be applied to the work field. The government should establish a compulsory training session for the trainers along with an incentive program so that they can catch up with up-to-date technology and trend. Third, the research shows that supporting business startup and job placement is important. Follow-up management systems should be provided in cooperation with relevant institutions of employment and business startups. Either outsourcing or placement of professional advisors is also needed.

The various designs are preferred as well as IT appliances development of the internet based with consumer needs. It's real that the tool development technology of shortened lead time is also requested for production tool fabrication for the launch of new products. A process technology for shortening tool development period was one of the very important practical education from tooling suppliers related to mold development, and we are in competition with having the three elements of short due date, the quality and the production cost for new products. In this paper, the tooling development education and training program with current product development won't be systematic, and we hope to improve educational training process lacking in the reality and to advance the application model of practical centered education and training program of practical technology ability improvement and process technology improvement for shorting tool development period which can be performed at the workplace substantially.

It is important for nursing faculties to try to improve their professional knowledge and skill in nursing education. Thus it is essential for them to participate in clinical training program. The purpose of this study was to identify the effect and satisfaction of faculty clinical training programs which were managed by Korean Academic Society of Nursing Education and 4 Hospitals(Samsung Medical Center, Seoul National University Hospital, Seoul, Asan Medical Center, Yeonsei Sebrance Medical Center) in Seoul. The data collection was done from July, 1999 to December, 1999 and the 125 subjects were used for the analysis. The purpose of participation of professor to clinical training course was found that to observe of up-to-date treatment method($3.57{\pm}.60$) and to connect between knowledge and practice ($3.63{\pm}.50$). The professors were highly satisfied with 'can see the high-tech institution and facilities($3.45{\pm}.62$)' and 'can confirm in advanced nursing field and practice ($3.38{\pm}.58$)' in clinical training program. And it was found that nursing professors applied the experience of participation in clinical training program to lecture and clinial practice for students. But they were dissatisfied with 'they had no or not enough time to practice'. In conclusion, the clinical training program was useful for nursing professor to educate and instruct the students. It is suggested that the more advanced course and practical program have to be developed for nursing faculties.

In this paper, a new method for lung area segmentation in chest radiographs has been presented. The movivation of this study is to include fuzzy informations about the relation between the image date structure and the area to be segmented in the segmentation process efficiently. The proposed method approached the segmentation problem in the perspective of pattern classification, using trainable pattern classifier, multi-layer perceptron. Having been trained with 10 samples, this method gives acceptable segmentation results, and also demonstrated the desirable property of giving better results as the training continues with more training samples.

Phishing websites can have devastating effects on governmental, financial, and social services, as well as on individual privacy. Currently, many phishing detection solutions are evaluated using small datasets and, thus, are prone to sampling issues, such as representing legitimate websites by only high-ranking websites, which could make their evaluation less relevant in practice. Phishing detection solutions which depend only on the URL are attractive, as they can be used in limited systems, such as with firewalls. In this paper, we present a URL-only phishing detection solution based on a convolutional neural network (CNN) model. The proposed CNN takes the URL as the input, rather than using predetermined features such as URL length. For training and evaluation, we have collected over two million URLs in a massive URL phishing detection (MUPD) dataset. We split MUPD into training, validation and testing datasets. The proposed CNN achieves approximately 96% accuracy on the testing dataset; this accuracy is achieved with URL schemes (such as HTTP and HTTPS) removed from the URL. Our proposed solution achieved better accuracy compared to an existing state-of-the-art URL-only model on a published dataset. Finally, the results of our experiment suggest keeping the CNN up-to-date for better results in practice.

Ontological knowledge modelling of epic texts, though being an established research arena backed by concrete multilingual and multicultural works, still suffers from two key shortcomings. Firstly, all epic ontological models developed till date have been designed following ad-hoc methodologies, most often combining existing general purpose ontology development methodologies. Secondly, none of the ad-hoc methodologies consider the potential reuse of existing epic ontological models for enrichment, if available. This paper presents, as a unified solution to the above shortcomings, the design and development of GOMME - the first dedicated methodology for iterative ontological modelling of epics, potentially extensible to works in different research arenas of digital humanities in general. GOMME is grounded in transdisciplinary foundations of canonical norms for epics, knowledge modelling best practices, application satisfiability norms, and cognitive generative questions. It is also the first methodology (in epic modelling but also in general) to be flexible enough to integrate, in practice, the options of knowledge modelling via reuse or from scratch. The feasibility of GOMME is validated via a first brief implementation of ontological modelling of the Indian epic Mahabharata by reusing an existing ontology. The preliminary results are promising, with the GOMME-produced model being both ontologically thorough and competent performance-wise.

Medical institutions wishing to install and operate diagnostic radiation generators must complete appointment training within one year of appointment based on the 「Medical Act」 and the 「Rules on Safety Management of Diagnostic Radiation Generator Devices」 which will come into effect on January 1, 2024. Additionally, You must receive supplementary education every three years from the date you received it. The strengthening of safety management for diagnostic radiation generators used in medical institutions means that although the radiation exposure that may occur when using diagnostic radiation generators is low, the risk of carcinogenesis may be higher than previously evaluated. In addition, safety management of diagnostic radiation generators can be said to be an essential requirement because it has been reported that the incidence of leukemia and other diseases is increasing in diagnostic radiation tests. However, the safety management training targets and programs for radiation exposure management operated by other organizations other than diagnostic radiation generators are significantly different. In addition, since the public institutions that are responsible for radiation safety management are divided, there is a risk of duplicative, excessive, and under-administrative application to medical institutions and educational institutions that install and operate diagnostic radiation generators. Therefore, we would like to determine their consistency by comparing domestic and foreign related cases and the provisions of the 「Medical Act」 and the 「Nuclear Safety Act」.

In spite of advanced navigational devices and reinforced mandatory standards of officers' education, the number of ship's accidents are increasing. The accidents caused by minor license officers are more than the number of accidents caused by superior license officers. There are many cases of collisions in the past 5 years released on Marine Accidents Inquiry Agency. Especially, officer's negligence from the consequences of the neglect of any precaution which may be required by the ordinary practice of seamen is the main reason behind ship's collisions. For reducing ship's accidents caused by human error, this paper suggests to develop effective training program using analysis date of domestic and foreign education system as a reference.

Background: Disabling fatigue is common in the working age population. It is essential that occupational health (OH) professionals are up-to-date with the management of fatigue in order to reduce the impact of fatigue on workplace productivity. Our aim was to evaluate the impact of one-day workshops on OH professionals' knowledge of fatigue and chronic fatigue syndrome (CFS), and their confidence in diagnosing and managing these in a working population. Methods: Five interactive problem-based workshops were held in the United Kingdom. These workshops were developed and delivered by experts in the field. Questionnaires were self-administered immediately prior to, immediately after, and 4 months following each workshop. Questionnaires included measures of satisfaction, knowledge of fatigue and CFS, and confidence in diagnosing and managing fatigue. Open-ended questions were used to elicit feedback about the workshops. Results: General knowledge of fatigue increased significantly after training (with a 25% increase in the median score). Participants showed significantly higher levels of confidence in diagnosing and managing CFS (with a 62.5% increase in the median score), and high scores were maintained 4 months after the workshops. OH physicians scored higher on knowledge and confidence than nurses. Similarly, thematic analysis revealed that participants had increased knowledge and confidence after attending the workshops. Conclusion: Fatigue can lead to severe functional impairment with adverse workplace outcomes. One-day workshops can be effective in training OH professionals in how to diagnose and manage fatigue and CFS. Training may increase general knowledge of fatigue and confidence in fatigue management in an OH setting.
