오늘날의 4차산업혁명시대에서는 전통적인 대기업보다는 신속하게 사업을 추진하는 스타트업이 혁신을 주도하고 있다. 스타트업은 문제 해결에 도전하는 활동을 수행하는 프로젝트 조직으로서, 개인사업자 또는 법인 등 법적으로 인정되는 기업을 설립하는 단계인 창업과는 분명히 구분되어야 한다. 다시 말해, 스타트업 활동을 통해 일정 수준 이상의 사업성을 검증하는 준비 단계의 창업 전 스타트업과 그 결과로 창업 과정을 거친 창업 후 스타트업으로 구분해야 한다. 또한, 현재 대부분의 대학교에서는 다양한 창업 교육교과/비교과 프로그램들을 진행하고 있는데, 실제 대학생 졸업 후 취업률 대비 창업률은 비율이 극히 낮은 실정이다. 이를 감안할 때 대학생에게 창업을 목표로 하기 보다는, 도전적인 창업가 정신을 함양하고 스타트업 활동 중심의 교육을 통해 자신의 진로 적성을 찾고, 그 분야의 스타트업에의 취업을 우선 목표로 하는 교육이 스타트업의 인력난 문제를 해결한다는 측면에서 볼 때 스타트업 생태계 발전에 보다 바람직하다. 본 연구에서는 먼저 캠퍼스 스타트업 문화 확산을 위한 교육 방향으로 스타트업 관련한 '경험 확대 - 진로 선택 - 실무 체험 - 진로 실행' 단계별 지원을 제안한다. 다음으로 실제 대학교에서 개설하고 운영한 일련의 교육 프로그램으로서 진로 지도, 스타트업 활동 이해, 스타트업 활동용 디지털 리터러시, 스타트업 협력 프로젝트, 스타트업 인턴 준비 교육 과정 및 결과들을 사례로 소개한다.

In this study, the harmless crack size was evaluated using carburized, quenched-tempered SCM822H steel. The possibility of detecting cracks that reduce the fatigue limit by non-destructive inspection was evaluated. The conclusions obtained are as follows. The retained austenite of surface was reduced by SP. About 35% and 65% of the retained austenite on the surface were transformed into strain-induced martensite, increasing the hardness by 79HV and 122HV over the as-received material. The maximum compressive residual stresses introduced on the surfaces were -695 MPa and -688 MPa, respectively. The fatigue limit increased by 1.48 times and 1.67 times, respectively, compared to the as-received material. The harmless crack size of SP specimen was determined differently depending on the shot ball size.

In this paper, a wireless communication-based sensor data monitoring device with an explosion-proof (Exd IIC) case was implemented to enable installation at explosion-risk industrial sites such as plants. In existing industrial plant sites, most of the temperature sensors and vibration and impact sensors are wired up to several kilometers, which takes a lot of time and money to bury long pipes and cables. In addition, there are not many cases where some wireless devices have been applied to actual plant industry sites due to communication quality problems. Therefore, in order to solve this problem, zigbee mesh wireless communication was applied to provide high reliability wireless communication quality to industrial plant sites, and the time and cost incurred in new or additional installation of sensors could be greatly reduced. In particular, in the event of loss or error of some wireless communication devices, the communication network is automatically bypassed or recovered to enable real-time data monitoring.

In this study, the mechanical properties of friction stir welded A6061-T6 were evaluated. This material is used as a battery pack case material for electric vehicles. The Vickers hardness, tensile strength, and yield stress of the friction stir welding (FSW) specimen were all smaller than those of the base metal specimen. As the heat input increased, the nugget zone widened, and there were differences in hardness according to the base metal zone, heat affected zone, thermal-mechanical affected zone, and nugget zone. Mechanical properties were not proportional to heat input, and the thermal-mechanical affected zone on the advancing side was the smallest in all conditions. This is because the material flow speed increased on the advancing side, where the welding direction and the tool rotation direction were the same, forming a distinct boundary with mechanical deformation.

This study aims to find ways to increase the declining donation intention by using machine learning techniques. To this end, in order to predict factors that affect donations between the MZ generation and the senior generation, various machine learning algorithms, including logistic regression analysis, are applied to build a model to determine variables that affect donation intention, and provide statistical verification and evaluation indicators. In this study, differences in donation intention by generation were expected as a variable affecting donation intention, and the senior generation was expected to show a higher donation intention tendency than the younger generation. However, although the research results were not statistically significant, the younger generation showed a higher intention to donate, and these results are interpreted to mean that value consumption and ethical consumption, which are important to today's MZ generation, also influenced donations. However, there were differences between generations in the amount of donations, and higher donation amounts were confirmed among the senior generation (those in their 50s or older) than the younger generation. In addition, the results of the logistic regression analysis showed that previous donation experience had a positive effect on future donation intention, and the more motivation and importance of donation and various social participation activities online and offline, the more active one became in donating.

최근 미국을 중심으로 MOOC(Massive Open Online Courses) 열풍이 불고 있으며 전세계적으로 확산되고 있다. MOOC는 온라인상에서 누구나 수강할 수 있게 공개된 강의를 의미한다. 우리나라에서도 KERIS(Korea Education & Research Information Service)와 각 대학을 중심으로 많은 강의를 제공하고 있다. 본 논문의 목적은 MOOC의 현황과 개선안을 제시하는 것이다. 이를 위해 먼저 MOOC의 정의와 역사, 국내외 현황을 소개한다. 또한 개선안으로서 대학의 적극적인 참여와 캠퍼스 가치 창출, MOOC 기관의 수익모델 개발과 수료율 향상, LMS(Learning Management System)의 개발과 우수 강사 확보, 강의 번역 등의 과제와 함께 최종적으로는 MOOC가 제공하는 인증 시스템의 질 확보 문제 등을 다양하게 제시하였다.

Student halls and their convenient facilities have been a focal point for various student activities at university campus. It has been for most of the student a place of unique memories and of attachment often associated with those good and bad school days. However, it is questionable whether these facilities are supportive and accessible for all of the students and other users including the handicapped. Therefore, based on the concept of UD(universal design) which was widely applied to U.S. institutions, this study intended to evaluate student hall facilities in U.S. and to provide an improvement direction for Korean UD application. For that purpose, four universities were selected for an in-depth analysis and 76 survey indices were utilized based on previous research. It was found that (1) design consideration without braille sign for VIP(visually impaired person) in student buildings can be differently approached with electronic devices; (2) the best demonstration of UD in student buildings can be seen in spacious flat pathway, easy access through ramp and wide entry area, necessary for people in wheel-chairs, but used by all, implying an increase of the ratio of public space; (3) one of the good UD features is an attractive physical environment rather than institutional appearance, in which they ultimately will support and completely adaptable at optimal levels by everyone; (4) consistent maintenance and management maximize the potential of UD principles and minimize physical limitations.

The modern day architectural giant, Maki Fumihiko, has lived through both the early and the more recent modernism, Contemporary. In the 1950's he was faithful to the spirit that was founded on the early modernity, Metabolism. In his later years in the 2000's, his style can be distinguished into Neo-Modernism which was based on local influence. The educational system at Washington University and the modern city of Saint Louis carries the continuation of Fumihiko Maki's early and later architectural career. Steinberg Hall and Kemper Art Museum have been built adjacent to each other in an extended period of time. These two projects encompass the changes in the era that has gone through modernism, transformation of an architect's career, and the maturation of the university. Steinberg Hall carries the ideal and the spirit of young Fumihiko Maki, therefore, the basic platform of experimentation of the early Metabolist has been applied. Spatial theory that concentrates on the integration of relations is also evident in this project. In contrast, Kemper Art Museum expresses the work of a 78 year-old veteran from the perspective of Neo-Modernism. This piece focuses on the internal space through the coexistence of a variety of space, and with that it notably interprets the integration of the pieces to the whole as a set theory. The partial change that we see is the evidence of the change in the early and the later modernism, while maintaining the innocence and the spirit of it. This is to highlight the fact that, ultimately, the goal of architecture is to secure the human race's honesty and their freedom expressed through space.
