Purpose - The purpose of this study is to explore the introduction and activation of smart training for the effective training of vocational ability development of companies in the 4th industrial revolution era, we analyze the present status of smart training introduction and related difficulties and propose concrete activation plan. Research design, data, and methodology - Through the online survey, we tried to confirm the recognition of corporate about smart training. Questionnaires include what are the benefits, expectations, and difficulties of smart training, etc. The survey was conducted from August 21, 2017 to September 4, 2017. A total of 69 companies participated in the questionnaire. The questionnaire results were analyzed through frequency analysis and contents analysis. Based on the results of the questionnaire, we found out the cause of inhibition of smart training activation and suggested activation strategies. Results - The main reason for the provision of smart training is the expectation of the training performance and the recognition that it is possible to provide training in a flexible manner. The effectiveness of smart training operation was evaluated as a high level of contribution to the development of creative training course and the capacity of training institute. As a result of checking factors that hinders the activation of smart training, the most important reason is that the time and cost burden of the training institutes is excessive. The lack of expertise in the design of smart training courses and the burden of employers and trainees. Conclusions - In order to activate smart training, it is necessary to find solutions to the obstacles at the internal or external level of training institutions. The internal barriers to the training organization are lack of internal competence for preparation and course management. In this regard, we need to consider providing consulting, best practices or guidance in the process of designing and operating smart training. On the other hand, as an external obstacle factor, it is necessary to provide incentives to participate in smart training. In addition, further research is needed on strategies that can lead to participation in smart training from the viewpoint of employers and learners.

As personalized recommendation of products and services is rapidly growing in importance, a number of studies provided fundamental knowledge and techniques for developing recommendation systems. Among them, the CF technique has been most widely used and has proven to be useful in many practices. However, current collaborative filtering (CF) technique has still considerable rooms for improving the effectiveness of recommendation systems: 1) a similarity function most systems use to find so-called like-minded people is not well defined in that similarity is computed from a single perspective of similarity concept; and 2) temporal information that contains the changing preference of customers needs to be taken into account when making recommendations. We hypothesize that integration of multiple aspects of similarity and utilization of temporal information will improve the accuracy of recommendations. The objective of this paper is to test the hypothesis through a series of experiments using MovieLens data. The experimental results show that the proposed recommendation system highly outperforms the conventional CF-based systems, confirming our hypothesis.

The purpose of this study was to observe and analyze how pre-service secondary chemistry teachers conduct open-ended, free style, exploratory chemistry experiments. The study examined common difficulties and tendencies that teachers showed in the chemistry labs. The study also investigated how these teachers deal with their difficulties and obstacles, such as unexpected results and device errors. Next, the study explored how students' epistemic goals and considerations have been shaped and changed as they interacted with one another and participated in their experiments over time. The study suggests that it could be more effective to gradually decrease guided-features of the experiment by providing appropriate scaffolding, than to start with completely open-ended inquiry labs. The study also suggests that the establishment of epistemic agency among group members influences the way they conduct experiments. Consequently, it is necessary to consider how instructional design for open-ended inquiry labs may provide students with scaffolds to encourage their active participation and to build responsibility in group discussions.

Most studies of Korean Newspaper in historical view have focused on the news writing form and editorial practice. Those studies have much rely on the memories of ex-journalist or the impression of scholars. So this study aims to give the concrete figures of news writing forms and editing practices in 1920-30's by investigating Kim Dong-Seong's activities as a journalist. He was a first journalist who studies journalism. He studied journalism during his stay in the Ohio State University as an english department student. After he came back to Seoul, he worked at the Dong-A Il Bo as an one of the first publish members. His activities as a journalist have much important meanings because of his varied works and careers. He also wrote a practical affair book for reporters which was the first book in Korea. As a result of research about Kim Dong-Seong's activities in 1920-30's, the feature of edit practice in 1920's had much emphasis not only on the headline but on the relation between type and print, and at the same time the combination of news or the change of typography was one of methods which make the editing more variety. News materials were collected varied news sources and legworks by reporter. These results show us that such a news reporting practice in 1920-30's is similar co the contemporary.

The Korean government is attempting to promote technology-based start-ups and venture firms that can lead to new national growth engines being developed. Although government support policies focus on improving survival rates, strategic tools for sustainability management based on a continuing company's assumption are also relevant. Previous studies indicate corporate social responsibility (CSR) as an important strategic tool for the management of corporate sustainability. This research is an exploratory study that seeks to empirically analyze the applicability of such CSR to venture firms. Existing previous studies have been carried out by large companies and surveys, and there are limitations that do not reflect the characteristics of companies. To complement the shortcomings of previous studies and propose practical consequences, this study conducted an empirical analysis using raw data from government approval statistics to identify the growth stages of venture firms. Using the 2018 Survey of Korea Venture Firms, we identified the growth stages of domestic venture firms and used the data envelopment analysis (DEA) to investigate the effect of CSR activities on managerial efficiency. The analysis found that CSR during start-up and early growth cycles did not affect managerial performance. The organization that conducted enthusiastic CSR activities performed better than those that did not perform CSR activities since the rapid growth era. Ultimately, the scale efficiency of venture business was the highest from the rapid growth era when the CSR was not done. This study is a pioneering study that found that after the period of high growth, venture firms' CSR activities can affect managerial performance. Therefore, it is important to advise applicable policies and business decision-makers that CSR practices can be a tactical resource for improving performance of management.

Today, knowledge itself has become a resource which must be protected by the pertinent community of its contributors and users, from being manipulated or distorted by third-party players. The preservation of knowledge in relationship to the cultural context of its origins, has been recognized by international organizations intent on maintaining authentic voice and perspective. Globally, the WIPO (World Intellectual Property Organization) organizes the annual IGC (Intergovernmental Committee) meeting to address various issues associated with each country's utilization of intellectual and bio source property. Korean Medicine is the official name for the traditional medicine that has been inherited from the cultures of the Korean Peninsula. It is one of the four practices of East Asian Medicine including Traditional Chinese Medicine (TCM) from China, Kampo Medicine of Japan, and Sino-Vietnamese Medicine in Vietnam. As a cultural treasure representing centuries of evolving knowledge, Korean Medicine is protected under intellectual property rights afforded by WIPO, and must be understood in relationship to, and distinct from, TCM. It is understood that China has a strong political purpose to claim all the traditional medicines of the East Asian region under the name of TCM, including Korean Medicine. In fact TCM was authorized as the representative name for all East Asian medicine by decisions made by the ISO (International Standard Organization) in 2015. This paper proposes a pilot study on how to protect the intellectual property of Korean Medicine from efforts by China to claim it under the umbrella of TCM. Using the Uibang Yuchui (醫方類聚, Classified Collection of Medical Formulas) this paper suggests establishing a Database of UBYC, which was published in 1477 by the Joseon Korea government. UBYC was the reorganized version of contemporary East Asian medical sources, and has already hundreds of year's rich indigenous and culturally specific medical history of Korea, from which Korean Medicine has been built.

For the eco-friendly control of fruit rot of fig, disease incidences according to the cultural practices at 51 fig orchards in south coast area of Korea were surveyed in 2002, and the effect of soil mulch and potassium phosphonate on fruit rot of fig was evaluated from 2002 to 2004. Diseased fruits of fig orchards of open field, rain shading, and vinyl house were 33.3%, 7.5%, and 0%, respectively. Diseased fruits were rated at 34.6%, 35.7%, and 27% as the tree spacing of $2m{\times}2m,\;2m{\times}3m,\;and\;3m{\times}4m$, respectively. Among the soil mulching materials, barley straw showed disease incidence of 1.8% and 3.5% of diseased fruits compared to 42.1% and 48% of no mulching in 2002 and 2003, respectively. Diseased fruits in dark paper film mulching were recorded at 4.8% and 12% in 2002 and 2003, respectively, which were lower than those in dark polyethylene film mulching at 11.2% and 26.2%. When potassium phosphonate(1,000 ppm) was sprayed 3 times with 10 days intervals from the beginning of disease occurrence, disease incidences were rated at 3.0% and 2.0% in 2003 and 2004, respectively, which were much lower than those of control at 45.9 % and 39.3%.

Water quality model applicable paddy field was developed using field experiment during 1999 ${\sim}$ 2002. This model involves inputs from fertilization and sediment release as dirac delta function and continuous source function, respectively, and can simulate various processes such as ponded depth, surface drainage, total nitrogen concentration and total phosphorus concentration in a daily basis. The model was calibrated using data collected from field experiments which was irrigated with ground water and validated from field experiments which was irrigated with surface water. The nutrient concentration of surface water depended on the fertilization and dirac delta function can efficiently explain the valiance of nutrient concentration of surface water by fertilizer. As a result of calibration and validation, this model demonstrates good agreement. The model fit efficiencies ($R^2$) of ponded depth, surface concentration of TN and TP were 0.93,0.98 and 0.95, respectively for calibration, and those of TN and TP were 0.99 and 0.70, respectively for validation. We can apply lake and reservoir model to analysis paddy field considered with shallow ponded system, but it will need so many parameters and have much uncertainty. Fortunately, paddy field have a series of cultural practices yearly basis, such as irrigation-fertilization-forced drain-harvest with a similar time , so simple model may explain the mechanism for paddy field. Water quality model for paddy field developed in this study is simply, needs little parameters, but appeared high applicability to evaluate paddy filed drainage. We recommend this model to estimate nutrient loading from paddy field and establish best management practice.
