This study investigates how the emotion-based learning motivation enhancement program influences learning motivation and social support of college students. The developed final program consists of Learning Motivation I, Learning Coaching, and Learning Motivation II, which has 12 sessions. In each session, every student was guided to have reflection time by writing self-evaluation and reflection paper. The participants were 38 students majoring in engineering at K-college located in G city who took one liberal arts subject based on psychology during the 1st semester in 2016 and who were divided into an experimental group (19 students) and a control group (19 students) by non-probability sampling method. In the experimental group, emotion-based learning motivation enhancement program was totally processed 12 times, one class in a week, by one main lecturer and one assistant lecturer. For data analysis, independent sample t-tests, paired samples t-tests, and review analysis were conducted. The study results are as follows. First, the experimental group participating in emotion-based learning motivation enhancement program had more significant differences in learning motivation, and both self-confidence and self-contentment among sub-components than the control group. Second, the experimental group had no significant differences in social support, compared with the control group. The impression writing analysis of the experimental group showed that this program affected learning motivation and social support. Lastly, the study discussions and implications are described.

In this paper I undertake to define what is mind, as a partial project of the philosophical foundation of the Mind Humanities. To this end I ask myself, where can be found the field, to which the various or whole psychological concepts and discourses generally relate, and then I identify the correct field to be the field of existential activities of human beings as being-in-the-world. When human beings as being-in-the-world live their lives, her life is built up out of the internal biological activities, the worlds of space and time, and actions. While the various scenes of individual life of man produced by a dynamic coordination of those worldly components, the basis of the mechanism of that coordination is explained by a biological model of self-sufficiency system that I developed here. On the basis of this model, I show step by step, how and through which (logical) way organisms configures their living, as it is. With respect to those steps of the life-construction of the organism, or in light of each step corresponding to each configuration, I construct different types of mind, i.e. impulsive mind, manipulative mind, meta-mind, collective consciousness/mind and finally personality, while every mind is further subdivided. Finally, I define mind, in light of its function in human life and with respect to the generalized sense of the whole processes as outlined above, as an organ which weaves (above mentioned) worldly components to Dasein, and sublimates and expands it to a better living.

This study analyzes universities in Japan, which haves many similarities with those in Korea in certain aspects of the educational system and a common problem of reduced university admission resources, Korea's national university facility standards, policy related to nation-level university facility, and practical campus case. Through this, the study aims to examine the difference in the national approach and basic philosophy about university facilities in Korea and Japan, and also identify the major planning factors and improvement directions when establishing plans for university campuses in the future. The results of this study are as follows. First, Korea tends to promote policies related to university facilities by individual projects centered on a major pending problem or issue, while Japan has been shown to promote national university facility policies under a comprehensive mid-to-long-term plan by establishing a maintenance plan aimed at national university facilities every five years. Second, In the case of the university facility areas, the average university facility area of the examined universities in Japan is about 5.6% larger than the average university facility area in Korea. Additionally, the university facility area per student in Japan is about 13% wider than that of Korea. The total floor area of university facilities in Japan is also about 20.7% larger than that of Korea, and the university facility area per student in Japan is about 56.7% wider than that of Korea as well. Among support facilities, the total floor area of dormitories in Korea was 2.5 times wider than that of Japan, however, the acceptance rate of dormitory in Korea was 5.6% higher than Japan. Third, the university facility criteria items and systems of two countries are similar. but there are slight differences in the content such as the method of calculating student capacity, division classification, and the method of calculating the number of teachers.

In this study, annual maximum storm events are proposed to determined by the return periods considering total rainfall and rainfall intensity together. The rainfall series at Seoul since 1961 are examined and the results are as follows. First, the bivariate exponential distribution is used to determine annual maximum storm events. The parameter estimated annually provides more suitable results than the parameter estimated by whole periods. The chosen annual maximum storm events show these properties. The events with the biggest total rainfall tend to be selected in the wet years and the events with the biggest rainfall intensity in the wet years. These results satisfy the concept of critical storm events which produces the most severe runoff according to soil wetness. The average characteristics of the annual maximum storm events said average rainfall intensity 32.7 mm/hr in 1 hr storm duration(total rainfall 32.7 mm), average rainfall intensity 9.7 mm/hr in 24 hr storm duration(total rainfall 231.6 mm) and average rainfall intensity 7.4 mm/hr in 48 hr storm duration(total rainfall 355.0 mm).

This study was carried out to identify of C3G (cyanidin-3-glucoside) from mulberry fruits and quantify with different varieties. C3G of mulberry fruits was extracted with 1％ HCl-MeOH and purified with open column (5${\times}$90cm) which filled with Amberlite IRC-50 ion exchange resin. The $\lambda$max ranges of the purified C3G on UV/vis spectrum were 516nm and 280nm. Also, molecular weight of C3G from mulberry fruits by LC-Mass was determined as 449. From above results, we concluded that anthocyanin pigment of mulberry fruits was C3G only. The cyanidin-3-glucoside (C3G) was separated and quantified by High Performance Liquid Chromatography (HPLC) system using a Nova-Pack C$\_$18/ column. Mean content of the 35 tested accessions was 0.89％. Also fruity characteristics as well as C3G content to select the desirable mulberry varieties for the production of fruit were researched and analyzed. We selected three suitable varieties such as 'Susungppong', 'Kangsun', and 'Jeolgokchosaeng(Chungpuk)'.

Benzodiazepines (BDZs) drugs act on the GABA_A receptor, function as nerve suppressors, and are used to treat anxiety, insomnia, and panic disorder. We analyzed the data of 30 individuals to determine any differences in the sleep-electroencephalogram findings among individuals varying in age, benzodiazepine use, and duration of benzodiazepine use. Comparisons between users and non-users of benzodiazepines, short-term and long-term users, older and younger users, and older short-term and older long-term users, were achieved using electroencephalographic findings obtained through polysomnography. The parameters evaluated included sleep latency, sleep efficiency, sleep-stage percentages, number of sleep spindles, and average frequency of sleep-spindle. The difference between benzodiazepine users and non-users was significant with respect to sleep-stage percentages and average frequency of sleep-spindle. Older and younger users differed significantly with respect to sleep efficiency and sleep-stage percentages, whereas significant difference for sleep efficiency was obtained between long-term and short-term users. Taken together, our results indicate that BDZ consumption suppresses slow-wave sleep and increases the frequency of sleep spindles.

In order to confirm the academic authenticity of comparative education, the academic methodology which is also appropriate for the historical arrangement is the history. In this sense, this article focuses on the study of comparative education from the viewpoint of history of education and aims for a tentative approach to comparative education history. In every discipline, it is essential to organize the history of the discipline both for those majoring in it and for the development of the discipline itself. The conclusions obtained from this study are as follows. First, in general, the method of studying comparative education includes not only 'comparative studies' but also 'regional studies', but it can add academic depth through the study of time series called 'comparative education history'. Second, the developmental process of the comparative education can be classified into four stages; the first stage is 'the pre-history' of the comparative education, the second stage is the 'embryo stage', the third stage is the 'establishment stage', and the fourth stage is the 'development stage'. Especially, in the era of globalization, the academic potential of comparative education is even higher, so it is possible to add an 'expanding period'. Third, it is necessary to understand the 'comparative education history' in order to secure the academic identity of the comparative education study. It is expected that it will be possible to more easily confirm the perspectives and issues of comparative education in the future, together with a good conceptual understanding of comparative education.

The use of 3D printing (Additive Manufacturing) technology has expanded from initial model production to the mass production of parts in the industrial field based on the continuous research and development of materials and process technology. As a representative polymer material for 3D printing, the polyamide-based material, which is one of the high-strength engineering plastics, is used mainly for manufacturing parts for automobiles because of its light weight and durability. In this study, the specimens were fabricated using Selective Laser Sintering, which has excellent mechanical properties, and the flexural characteristics were analyzed according to the temperature of the two types of polyamide 12 and glass bead reinforced PA12 materials. The test specimens were prepared in the directions of $0^{\circ}$, $45^{\circ}$, and $90^{\circ}$ based on the work platform, and then subjected to a flexural test in three test temperature environments of $-25^{\circ}C$, $25^{\circ}C$, and $60^{\circ}C$. As a result, PA12 had the maximum flexural strength in the direction of $90^{\circ}$ at $-25^{\circ}C$ and $0^{\circ}$ at $25^{\circ}C$ and $60^{\circ}C$. The glass bead-reinforced PA12 exhibited maximum flexural strength values at all test temperatures in the $0^{\circ}$ fabrication direction. The tendency of the flexural strength changes of the two materials was different due to the influence of the plane direction of the lamination layer depending on the type of stress generated in the bending test.

In this study, to optimize the production and utilization of biogas for organic waste resources, the precision monitoring of on-site facilities and the energy balance by facility were analyzed, and the solutions for field problems were investigated, and the design and operation guidelines for pretreatment facilities and generators were presented. Gas pre-treatment is required to solve frequent failures and efficiency degradation in operation of high quality refining facilities, and processing processes such as desulfurization, dehumidification, deoxidization, dust treatment, volatile organic compounds, etc. Since these processes are substances that are also eliminated from the high-quality process, quantitative guidelines are not presented in the gas pretreatment process, but are suggested to operate during the processing process as a qualitative guideline. In particular, dust, siloxane, and volatile organic compounds are the main cause of frequent failure of high-quality processes if they are not removed from the gas pretreatment process. Design of the biogas high-quality process. The operation guidelines provide quality standards [Methane content (including propane) of 95% or more] with 90% or more utilization of the total gas generation, two systems, and a margin of 10% or more. It also proposed installing gas equalization tank, installing thermal automatic control system for controlling equalization of auxiliary fuel, installing dehumidification device at the back of high quality for removing moisture generated in the process of gas compression, installing heat-resisting facilities to prevent freezing of facilities in winter and reducing efficiency, and installing membrane facilities in particular.

Since 2015, the government has been striving to strengthen the software capabilities required for future talent through software-oriented university in Korea. In the university selected as a software-oriented university, basic software education is given to all departments such as humanities, social science, engineering, natural science, arts and the sports within the university in order to foster convergent human resources with different knowledge and software literacy. In this paper, we analyze the contents of basic software education for twenty universities selected as software-oriented universities. As a result of analysis, most of the basic software education which is carried out to the students of the non-majors students was aimed at improvement of problem solving ability centered on computational thinking for future society and improvement of convergence ability based on computer science. It uses block-based educational programming language and text-based advanced programming language to adjust the difficulty of programming contents and contents reflecting characteristics of each major. Problem-based learning, project-based learning, and discussion method were used as the teaching and learning methods for problem solving. In the future, this paper will help to establish the systematic direction for basic software education of non-majors students.
