2016년 1월 다보스 세계경제포럼에서 제4차 산업혁명이라는 화두가 세상에 던져진 이후 세계는 사회·경제적으로 큰 변화를 겪고 있다. 이에 본 연구에서는 제4차 산업혁명시대에 품질경영의 방향에 대해 살펴보았다. 첫째로 미국, 독일, 일본 및 중국에서는 제4차 산업혁명시대에 사물인터넷, 로봇공학, 3D프린팅, 빅데이터, 인공지능 등의 새로운 정보통신기술과 기존 기술 및 산업과의 융합으로 산업구조가 변화되고 새로운 스마트 비즈니스가 창출되고 있다는 것을 확인했다. 둘째로 우리나라의 제4차 산업혁명의 핵심 기술수준은 선진국에 비해 미흡한 편이지만 2015년부터 새로운 환경에 적극 대응하기 위해 새로운 정보통신기술을 이용하여 스마트 생산방식 확산, 신산업 창출 등에 힘써오고 있다는 것을 파악했다. 마지막으로 제4차 산업혁명시대에 품질경영은 제품이나 서비스의 기획 및 설계단계에서부터 빅데이터 기반으로 시장의 요구를 실시간으로 반영한 것을 새로운 정보통신기술로 실시간 구현하는 것이라는 것을 확인했다.

The $4^{th}$ industrial revolution has brought innovation in the educational environment. The purpose of this study is to verify the educational effectiveness of smart learning environment especially with the computational thinking. A big data analysis was performed to confirm that computational thinking is the one to prepare the 4th industrial revolution. To teach computational thinking at university, educational design should be careful. This study verified the relationship between improvement of computational thinking ability and major of students with coding education. There was difference in effectiveness of the coding education depending on the major of students, it means students must be guaranteed to be educated by the differentiated coding education for different major. This study extracted factors of computational thinking through literature review. Thirteen research hypotheses were applied for the statistical analysis in R language. It was proved that expectation of class and improvement of abstraction ability and algorithmic thinking ability had mediation effect to the relationship between knowledge acquisition and problem-solving abilities. Based on this study, effectiveness of education can be improved, and it will lead to produce a lot of distinguished students who are ready for the 4th industrial revolution.

This paper analyzes the existing transportation systems of Nigeria and Korea and proposes a new railway and roadway design for Nigerian cities. The research findings and feasibility study revealed that the state of Nigeria's transportation system was critical as was its market segment, infrastructural deficit and financial requirement needed to implement a smart transportation system. The dilapidation of the existing infrastructure coupled with poor maintenance culture and limited public transport services has hindered the economic growth of Nigeria and its cities. A case study of Korea and Japan shows some possible solutions to Nigeria transportation challenges. Analytical and descriptive methods were used to critically assess the infrastructural challenges, movement, and convenience. The study proposed the design of a new intercity railroad and roadway across Abuja, Enugu, Lagos and Port Harcourt cities. The proposed designs have been established to be an innovative solution with advanced benefits over the current system. The implementation of the proposed designs is estimated to cost about US$(77,832,027,719) across the study areas. Thus, the discussion, conclusion, and recommendations given present a proposal to the Nigerian government on the possibility of solving the Nigerian intercity railroad and roadway transportation challenges across Abuja, Enugu, Lagos and Port Harcourt cities through smart designs.

As technologies have been developing, our lives are getting easier. Today we are surrounded by the new technologies such as AI and IoT. Moreover, the word, "smart" is a very broad one because we are trying to change our daily environment into smart one by using those technologies. For example, the traditional workplaces have changed into smart offices. Since the 3rd industrial revolution, we have used the touch interface to operate the machines. In the 4th industrial revolution, however, we are trying adding the speech recognition module to the machines to operate them by giving voice commands. Today many of the things are communicated with human by voice commands. Many of them are called AI things and they do tasks which users request and do tasks more than what users request. In the 4th industrial revolution, we use smartphones all the time every day from the morning to the night. For this reason, the privacy using phone is not guaranteed sometimes. For example, the caller's voice can be heard through the phone speaker when accepting a call. So, it is needed to protect privacy on smartphone and it should work automatically according to the user context. In this aspect, this paper proposes a method to adjust the voice volume for call to protect privacy on smartphone according to the user context.

Smart Factory is a part of and a key point of the 4th industrial revolution. It performs optimization from the whole viewpoint, using comprehensive data of the post-process data by utilizing various sensors, controllers, and mobile devices beyond the existing factory automation level. In this paper, we design and implement an IoT platform that can detect the safety factors of the workers, the environmental factors of the factory, and real time monitoring at the control center, among the fields to implement smart factory. To accomplish this, we construct a monitoring device that provides sensor information control, server transmission of sensor information, and visualization of collected information. By using this system, it is possible to maintain the temperature and humidity for the optimum working environment in the factory. and also, By using the beacon, it is possible to measure the working time of the worker and trace the position.

최근 4차 산업혁명과 스마트 팩토리라는 용어를 뉴스나 매체를 통해 자주 들을 수 있다. 하지만 스마트 팩토리에 대한 정보와 어떻게 스마트 팩토리를 구축해야 하는지에 대한 구체적인 가이드라인이 없기 때문에 기업들로부터 외면 받고 있다. 스마트 팩토리의 구축은 도입 목적을 고려하여 회사의 규모에 적합하게 수행되어야한다. 기존 논문 연구에서 국내 대 중 소기업들을 대상으로 스마트 팩토리 성공구축 사례들을 분석 하였다. 사례분석 결과, 대기업의 경우 일부공장을 대상으로 시범적으로 스마트 팩토리를 구축한 후 성공적으로 평가될 시 전체공장으로 확대시키는 전략이 효과적이다. 중소기업의 경우, 낮은 수준의 스마트 팩토리 구축레벨에서 높은 수준의 구축레벨로 업그레이드하는 것이 효과적이다. 본 논문에서는 전통제조업체를 1개 선정하고, 3D가상공정설계를 통해 병목 구간과 개선이 필요한 공정을 파악한 후 센서를 설치한다. 최종적으로 센서를 통해 수집 된 데이터를 분석한 후 공정을 개선하고, 생산성이 향상된 스마트 팩토리를 구축하여 그 효과를 검증해 보고자 한다.

As the $4^{th}$ industrial revolution is accelerating, IT convergence application technologies are attracting attention in various fields. In the manufacturing industry, Smart Factory technology, which is blended with IT technology, has been developed to solve the problem casued by the decrease of the labor force, and a monitoring server is required to remotely control the equipment or to inquire about the operation status of the factory. In this paper, we designed and implemented RESTful API for data sharing between factory equipment and monitoring server in Smart Factory. In order to verify the designed API, a testbed was operated for an actual plastics manufacturing plant. As a result, it was confirmed that the testbed can be operated normally in actual operating environment.
