Researches on the introduction of ERP system kept on examining the critical successful factors (CSFs) that focus on factors to achieve effectively successful projects, and trying to measuring the actual effectiveness of the introduction of ERP system. However, most of the preceding researches on the effectiveness of the introduction of ERP system that was searching devoted effects has been ceased, and actually even researches on the economical results have just done the basic cognitive evaluation of result indicators by many questionnaires instead of objective measuring values, because of the difficulty of measuring the evaluation of the result. Moreover, researches on positive effects of the introduction of ERP on enterprise results and researches that failed to give advantageous effects showed different results each other. And a part of researches reported that only a part of result indicators were partially affected. In this research, we investigated Korean large enterprises or middle-sized enterprises in manufacture industry that introduces SAP R/3 and Oracle package to compare their quantitative financial results after the introduction of ERP system, in order to measure the effects of the ERP system. First, we evaluated the difference of the quantitative financial results before and after the introduction of the ERP system. Second, we evaluated the opportunities shown by the effects after the introduction of the ERP system. Third, we removed the sample of the exchange crisis (IMF) and executed the additional analysis to reflect the average increasing and decreasing rate in the industry, so that pure evaluation can be achieved. Inherent limits of precedent researches are removed and practical effects of the pure introduction of the ERP system are evaluated, so the research of this research is significant. The result of this research is as follows. Because of the introduction of ERP, the rate of turnover of inventory property has increased and sales of preparation inventory property have decreased so that more effective inventory property management has been achieved. Moreover, preparation sales of labor costs and preparation sales of the number of employees have decreased to show the effect of the reduction of labor costs. However, it could no be concluded that we could increase the profit due to the introduction of ERP system. Due to the introduction of ERP, although we concluded that the return on assets (ROA) and the additional value of one-person employee statistically showed obvious differences and increased, the return on equity failed to show obvious differences after the process of introduction of ERP.

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.

This study is on the introduction of the natural logarithm by the quadrature of the hyperbola. In School mathematics curriculum, Logarithm is introduced formally. But in that introduction, students could't know the meaning of the natural logarithm and e well. Historically, natural logarithm is related to the quadrature of the hyperbola. So in this study we consider the introduction of the natural logarithm by the means of quadrature of the hyperbola and the significance of the introduction.

This paper investigated the qualitative introduction status of domestic major construction company. And that focused on a point of suggestions about CM at Risk introduction. The survey analysis showed that three importan suggestions. First, the biggest obstacles factors to CM at Risk introduction that related laws is lagging amendment. Second, we have to improve the available hands ability in domestic major construction company. And last, we have to do that using uncomplicated design and standard design form. Consequently, environmen analysis for the introduction and example project is urgently required.

Cold storage and transportation facilities play major roles in the implementation of fishery cold chain systems. Most fishes are more easily perishable than other food products such as agricultural products and livestock products. Therefore, fishery cold chain systems were earlier introduced than other food clod chain systems. It is acknowledged that a reefer ship as a component of cold chain systems was used in the fishery transportation in the Joseon Dynasty. But researchers disagree on the introduction time of a fishery reefer ship. This study investigated the introduction time of a fishery reefer ship by some conditions including the number of private cold storage facilities, the magnitude of fishing vessels, and the plenty catch of fish species. According to reviewing the introduction conditions of fishery reefer ships, it was estimated that fishery reefer ships were introduced in 15th century. Therefore, the introduction time of a fishery reefer ship is more advanced about 300 or 400 years than as we know.

Introduction to Medicine (Euihak-Ipmun), written by Lee Chun of the Ming Dynasty, is a comprehensive medical book brought to Joseon in the 1600s. It directly influenced many medical books written in the Joseon Dynasty of the same period, and became a major citation document of Dongui-Bogam. Introduction to Medicine became a major text for medical education in 1834 and has since been used as a clinical primer of Korean medicine. This article first examines the Joseon's era published version of Introduction to Medicine using documentation of the Diary of the Royal Secretariat (Seungjeongwon Ilgi), and a woodblock list. Based on these investigations, the reviewer examined the existing versions of the book, and focused on various characteristics for comparison. This article reveals facts which include : 1) All editions of Introduction to Medicine published at the present office are published by Jeolla-do provincial office (Jeolla-Gamyeong). 2) The first edition was published before 1636. 3) A finely produced version (Jeongganbon) was published around 1760. 4) The Jeongrijache-iron type publication was published around 1801.

Recently, various studies regarding introduction of RFID have been implemented in many industries including logistics field. The objective of this study are (i) to analyze an economical effect due to the introduction of RFID on ULS(Unit Load System) Pallet, (ii) to develop a model to estimate cost of RFID introduction, and (iii) to establish a foundation for activating introduction of RFID to the logistics field in order to increase efficiency. This study utilized data regarding fifty logistics companies' awareness of RFID usage. The result of the economical analysis showed B/C of 2.766 and NPV of 2.6 billion won, which implies significant benefit to the logistics industry. This study is meaningful in that it is the first study to quantitatively estimate the effect of RFID introduction on ULS pallet in Korea.
