The purpose of this paper was to identify the relationship among the MBTI personality types, self-efficacy, major satisfaction and freshmen's academic achievements in airline service department. To this end, a survey was conducted in 113 university freshmen of airline service department from June 18 to 29, 2018. And the data were collected their MBTI results and GPA scores. MBTI results used to analyze student's personality type. The collected data were analyzed using 'SPSS Statistics 21.0'. Analysis methods such as frequency analysis, cross-tabulation analysis, factor analysis, reliability analysis, t-test, ANOVA, and multiple regression analysis were used. The findings of this study are as follows. The type of personality in the airline service department affects the self - efficacy such as self - control efficacy, confidence, preference of the task difficulty, and also affects the major satisfaction and the academic achievement. The self - efficacy affects the major satisfaction and the academic achievement, and also the major satisfaction can affect academic achievement. Therefore, by developing an effective teaching strategies that fits students' personality type characteristics, and by inducing motivation to learn, raising self-efficacy naturally will lead to higher major satisfaction and academic achievements.

As technology rapidly develops, the demand for manpower by new industries is increasing. In order to respond to the changing demands of the workforce, universities are actively introducing interdisciplinary majors, which is a program formed by two or more departments cooperating to develop new majors. Although the importance of the interdisciplinary major is increasing, universities have difficulties managing them due to non-flexible educational systems. The purpose of this study is to present an effective management direction for interdisciplinary majors based on the results of a survey on student satisfaction with interdisciplinary majors. Also, we analyzed the required level and possessed level of the IS practitioners' competencies, and developed specific educational directions for training IS talents. The results showed that there was a significant difference in satisfaction with the curriculum development and curriculum evaluation of existing subjects provided by existing departments and new subjects established of interdisciplinary majors, specifically the satisfaction of new subjects is higher than existing subjects. In the IS field, there was a high demand for education in the following areas, in order: information security, information technology strategy planning, information technology operation, information technology development, information technology management, information technology sales, and core competencies. Based on the results of the analysis, the satisfaction of students and the cultivation of the talents that the interdisciplinary major aims to develop can be improved.

본 연구에서는 한반도 서울의 연세대학교에서 Multi-Axis Differential Optical Absorption Spectroscopy(MAX-DOAS)장비로부터 산출된 원시자료를 이용하여 처음으로 최적추정(Optimal Estimation; OE)을 사용하여 오존전량 및 오존의 대류권 프로파일을 산출하였다. 오존전량 및 오존의 대류권 프로파일을 산출하기 위하여 최적추정을 통하여 MAX-DOAS자료의 광학두께 피팅을 수행하였다. 광학두께 피팅은 MAX-DOAS 장비로부터 각각의 기기 고도각별로 관측된 값을 천정각에서 관측된 값으로 나누어 계산된 자료를 통하여 수행하였다. 오존전량은 2017년 5월 23일 오전(08:13)과 오후(17:55)에 각각 375.4와 412.6 DU로 산출되었다. 오존의 대류권 프로파일(<10 km)은참값 오존존데와 비교하여 약 5% 이내의 오차로 산출되었다. 하지만 10 km 이상의 높은 고도에서는 산출 에러가 커져 10% 이상 과대추정 하는 것으로 산출되었다. MAX-DOAS 자료의 스펙트럼 피팅에 의한 오차는 오전과 오후에 각각 16.8%와 19.1%로 계산되었다. 본 연구에서 제시한 방법은 지상관측 기반의 초분광 UV 센서를 이용하여 오존전량과 대류권 오존 프로파일을 산출하는데 유용하게 사용될 수 있다.

In this papers, we proposed the feature extraction method due to partial discharge type of transformers. For wavelet transform, Daubechie's filter is used, we can obtain wavelet coefficients which is used to extract feature of statistical parameters (maximum value, average value, dispersion, skewness, kurtosis) about acoustic emission signal generated from each partial discharge type. The defects which could occur in a transformer were simulated by using needle-plane electrode, IEC electrode and Void electrode. Also, these coefficients are used to identify signal of partial discharge type electrode fault in transformer. As a result, from compare of acoustic emission amplitude and acoustic average value, we are obtained results of IEC electrode> Void electrode> Needle-Plane electrode. otherwise, In case of skewness and kurtosis, we are obtained results of Needle-Plane electrode electrode> Void electrode> IEC electrode.

The remote monitoring and warning system for dangerous chemicals is designed with the concept of the Cyber-Physical System (CPS) in this paper. The real-time perception, dynamic control, and information service of major hazards chemicals are realized in this CPS system. The CPS system architecture, the physical layer and the applacation layer, are designed in this paper. The terminal node is mainly composed of the field collectors which complete the data acquisition of sensors and video in the physical layers, and the use of application layer makes CPS system safer and more reliable to monitor the hazardous chemicals. The cloud application layer completes the risk identification and the prediction of the major hazard sources. The early intelligent warning of the major dangerous chemicals is realized and the security risk images are given in the cloud application layer. With the CPS technology, the remote network of hazardous chemicals has been completed, and a major hazard monitoring and accident warning online system is formed. Through the experiment of the terminal node, it can be proved that the terminal node can complete the mass data collection and classify. With this experiment it can be obtained the CPS system is safe and effective. In order to verify feasible, the multi-risk warning based on CPS is simulated, and results show that the system solves the problem of hazardous chemicals enterprises safety management.

The present discourse lasts around, information pollution, causes and concerns of information pollution, internet as a major causality and how it affects the decision making ability of an individual. As, information producers in the process to not to lose the readership of their content, and to cater the information requirements of both the electronic and the print readers, reproduce almost the whole of the printed information in digital form as well. Abundant literature is also equally produced in electronic format only, thereon, sharing this information on hundreds of social networking sites, like, Facebook, Twitter, Blogs, Flicker, Digg, LinkedIn, etc. without attributions to original authors, have created almost a mess of this whole information produced and disseminated. Accordingly, the study discusses about the sources of information pollution, the aspects of unstructured information along with plagiarism. Towards the end of the paper stress has been laid on information literacy, as how it can prove handy in addressing the issue with some measures, which can help in regulating the behaviour of information producers.

By the research of the actual state of food consciousness as the object of male, female 421 college students by major, non-major in food dietetics, the results are as follows. The validity degree of the guestion article appeared at the analysis of the knowledge of nutrition(the figure of Cronbach "${\alpha}$" overall 0.58, major 0.62, non-major 0.57). In the interest degree about nutrition knowledge of the major students were significant(P<0.05), but the non-major students were not significant, and there was a difference between two groups of the male and female, major and non-major students in the information about knowledge. The knowledge of the major students mostly get from school education, non-major from mass communication as TV and rodio, etc. There was not significant difference in self-consciousness degree of health of all the male, female students by major, non-major, and the self-consciousness degree about health of should not be significant to the food habit. Therefore deviating from acquirement of nutrition knowledge by the wrong medium of food consciousness of home dietary life, improvement plans should be activated for the right knowledge to practice in actual life. Taking the opportunity of food and nutrition education through literary subject in the curriculum of the college for students, good food consciousness must be properly applied all the part of dietary life, and it is urgent for them to carry out scientific and reasonable curriculum and educational material development.
