  • One of the objectives of any task design is to provide a safe and helpful workplace for the employees. The safety and health module may include means for confronting the design with safety and health regulations and standards as well as tools for obstacles and collisions detection (such as error models and simulators), Virtual Reality is a leading edge technology which has only very recently become available on platforms and at prices accessible to the majority of simulation engineers. The design of an automated manufacturing system is a complicated, multidisciplinary task that requires involvement of several specialists. In this paper, a design procedure that facilitates the safety and ergonomic considerations of an automated manufacturing system are described. The procedure consists of the following major steps. Data collection and analysis of the data, creation of a three-dimensional simulation model of the work environment, simulation for safety analysis and risk assessment, development of safety solutions, selection of the preferred solutions, implementation of the selected solutions, reporting, and training. When improving the safety of an existing system the three-dimensional simulation model helps the designer to perceive the work from operators point of view objectively and safely without the exposure to hazards of the actual system.

  • Action recognition has been studied in computer vision field for years. We present an effective approach to recognize actions using a dimension reduction method, which is applied as a crucial step to reduce the dimensionality of feature descriptors after extracting features. We propose to use sparse matrix and randomized kd-tree to modify it and then propose modified Local Fisher Discriminant Analysis (mLFDA) method which greatly reduces the required memory and accelerate the standard Local Fisher Discriminant Analysis. For feature encoding, we propose a useful encoding method called mix encoding which combines Fisher vector encoding and locality-constrained linear coding to get the final video representations. In order to add more meaningful features to the process of action recognition, the convolutional neural network is utilized and combined with mix encoding to produce the deep network feature. Experimental results show that our algorithm is a competitive method on KTH dataset, HMDB51 dataset and UCF101 dataset when combining all these methods.

The Critical Thinking Education for Development of Creativity in Engineering Students: Focusing on Critical Writing about the Film "Bowling for Columbine" (공학도의 창의성 계발을 위한 비판적 사고 교육: 영화 《볼링 포 콜럼바인》에 대한 비판적 글쓰기를 중심으로)

  • The purpose of this study is to clarify that critical writing can be a positive stimulus factor for the cultivation of critical thinking through actual cases of writing education targeting engineering students in universities. Critical writing education is a very important way to develop critical thinking necessary for acquiring scientific knowledge, sharing social values, creativity and cultivating new production capacity. Especially, when critical writing education is performed with materials that maintain critical view of social reality such as the movie "Bowling for Columbine", it is characterized by the fact that it is naturally combined with the dimension of engineering ethics faced by engineers from the analysis and judgment of social reality. This is an example of the fact that critical thinking education for engineering students does not necessarily meet their major areas.

'Cook and Restaurant' reality program, structure, representation, and its cross-cultural implications: A comparative study between and of tvN ('요리 및 식당'의 리얼리티 프로그램의 구성과 재현의 의미와 문화 함축성 - tvN <윤식당1>과 <윤식당2>에 대한 기호학적 비교분석)

  • The purpose of this study was to find out the presentation of food and cooking process shown through the media and its cultural implications by comparing and analyzing seasons 1 and 2 of , tvN's reality program which has gained high viewer ratings and sympathy from the viewers. In light of the existing documents, the research reviewed the social and cultural meanings implied through a series of processes of "the act of cooking- the act of providing food - the act of having a meal."The authors concerned narrative structure of the program, paradigmatic analysis, actantial analysis, and analysis by applying the culinary triangle of $L{\acute{e}}vi$-Strauss were conducted, in order to find out the difference between seasons 1 and 2 of the . As a result of semiotic analysis on the programs, by focusing on the value of composure and slowness which may be felt through the simple everyday lives and travelling by running a Korean restaurant in a foreign country, the reality program revealed the changed consumption behaviors for Korean food, and the evolutionary process of cooking and the act of providing food reflecting the above. Meanwhile, the transformation of the Korean food may mean the "statelessness of Korean food" hidden under the name of localization or globalization. Furthermore, although the program intended to put up globalization of Korean food, the uniqueness of the Korean food wash armed, and this is the reason why it needs to be examined whether Korean food was used simply for entertainment in the program. Also, the program showed limitations such as drawing cultural inferiority as the motive for watching the program.
