Job seekers are making various efforts to find a good company and companies attempt to recruit good people. Job search activities through self-introduction essay are nowadays one of the most active processes. Companies spend time and cost to reviewing all of the numerous self-introduction essays of job seekers. Job seekers are also worried about the possibility of acceptance of their self-introduction essays by companies. This research builds a classification model and conducted an experiments to classify self-introduction essays into pass or fail using deep learning and decision tree techniques. Real world data were classified using stratified sampling to alleviate the data imbalance problem between passed self-introduction essays and failed essays. Documents were embedded using Doc2Vec method developed from existing Word2Vec, and they were classified using logistic regression analysis. The decision tree model was chosen as a benchmark model, and K-fold cross-validation was conducted for the performance evaluation. As a result of several experiments, the area under curve (AUC) value of PV-DM results better than that of other models of Doc2Vec, i.e., PV-DBOW and Concatenate. Furthmore PV-DM classifies passed essays as well as failed essays, while PV_DBOW can not classify passed essays even though it classifies well failed essays. In addition, the classification performance of the logistic regression model embedded using the PV-DM model is better than the decision tree-based classification model. The implication of the experimental results is that company can reduce the cost of recruiting good d job seekers. In addition, our suggested model can help job candidates for pre-evaluating their self-introduction essays.

In Korea, livestock has grown into the most value-added business in the agricultural and forest industry. But due to the recent outbreak of deadly infectious diseases such as foot-and-mount disease and avian influenza (AI), the demand for IT-enabled cutting-edge management system is getting stronger. As for humans, pilot projects and researches concerning U-healthcare have been carried out since early 2000. So this study explored the current progress of U-healthcare introduction, and suggested the strategies to develop technologies of collecting, processing, and utilizing information; to apply elements for a service model development and prioritization; to provide policy and institutional support. Therefore it is expected to vitalize the livestock U-healthcare in the future through continuous study based on these results.

Recently orders of projects in the field of oil and gas plants have increased due to rising oil prices and consumption. The markets of oil and gas plants are expanding into the Middle East area and all over the world. Because the oil and gas markets have a lot of overseas construction operations, competition among advanced companies is more important. However, companies in the period of growth have not had enough competitive powers of license in the design phase. Therefore, they are faced with difficulty of adopting the technology which is maximizing the effect of investments, and scheduling of a long-range plan. In order to achieve adequate technology management and competitive power, this study considers a long-range plan through an analysis of an appropriate introduction and the strategic planning process of technology management.

In this study, for the introduction factors of ERP system suggested in the prior study, I analyzed the importance of each introduction factor by using Delphi methodology and AHP. As a result of analysing the importance of the introduction factors of the 1st layer, the supplier factor was analyzed to be the most important factor among innovation factor, information technology factor, the user factor, the supplier factor, and in the weight analysis on the 2nd layer considering the importance of 1st layer, the standard work model of the supplier factor was a suitable factor, and the CEO participation factor(.086) was analyzed as the second most important introduction factor. These analysis results enable to determine that domestic Small & Medium enterprises' position hope to introduce by selecting a system in which the company characteristics and management strategies are applied well, because they should operate an ERP system that has already been developed, and in this course, the participation of CEO was also found to be a very important factor.

In line with the low growth trend of the global economy, shipping companies and port companies are experiencing various management difficulties. However, at this time when the growth trend is stagnating, attempts to solve the breakthrough in growth with the technology of the 4th industrial revolution are occurring in various industries and technologies. In this study, in order to facilitate the construction of smart ports in the future, we will look at the current port system in Korea, and in the sense of the need for a basic study to diagnose the direction for more smooth policy introduction and technology introduction, Related exploratory studies were conducted. To achieve the purpose of this study, various previous studies were reviewed, news articles related to ports, reports of the Ministry of Oceans and Fisheries, and foreign literature were reviewed in a variety of ways, and based on this, we intend to present smart port introduction tasks and improvement plans.

Currently, new terms are overflowing with the development of technology from VR, AR, XR to Metaverse. Every time a term is generated in this way, society considers it a new technology and tends to use it enthusiastically, but there is confusion in correctly understanding and utilizing the category of the term. He would like to discuss the virtual studio that played an important role in the development of broadcasting CG (Computer Graphics) technology in the 1990s, and talk about the introduction of new terms in the past and how to use them. Therefore, this paper examines the gap between chaos and upright each time a term is generated based on the time when the virtual studio is introduced, and analyzes the utilization of new technology from the past through the introduction machine manufacturing case. By examining the past technological development processes expressed by remediation, this paper argues that the current situation is not a new technology but an expression of a new term, that is, a phenomenon that appears during the gradual development of technology. It is something to do.

The death rate in the construction industry, which is more than twice that of other industries, increases the need to solve chronic safety problems. In a situation in which the safety management measures that have been maintained thus far are unable to reduce construction accidents, the introduction of smart construction safety technology (SCST) that reflects the 4th industrial technology is required for the safety management of workers. Large corporations or public institutions have introduced SCST and are operating pilot sites, but SCST is still in its infancy and there have yet to exist field data regarding necessity and effectiveness. In this study, the concept of SCST, which has still to be established, is defined, and the actual condition of SCST was analyzed through a survey. Through the analysis of the necessity of SCST introduction, convenience, and effectiveness before and after its application, problems such as problems from the field point of view as well as other factors hindering the introduction of such technology are derived in detail. In addition, an effective combination of technologies for safety management at the current level is determined and an activation plan is presented.
