In the era of the forth Industrial Revolution, open source code and open source hardware have gained much attention. In particular, 3D printing technology is expanding into the realms of classical science, technology and our daily lives. Relatedly, in the present study, we demonstrate the manufacture of a nano-LC MALDI spotter robot using 3D printing technology. The parts of the spotter robot were either made using a 3D printer or purchased as 3D printer parts from the 3D printer online market, so that anyone can make the robot without a deep knowledge of engineering or electronics, i.e., DIY (do-it-yourself) product. In the nano-LC MALDI spotter, the nano-LC eluent and MALDI matrix were mixed in a T-union and discharged from the capillary outlet. The eluent and matrix mixture could be spotted onto the movable MALDI plate. The MALDI plate was designed to translate in a two-dimensional space (xy plane), which was enabled by the movements of two stepper motors. In the paper, all computer-aided design (CAD) files for the parts and operation software are provided to help the reader manufacture their own spotter robot.

In this study, we provide full descriptions of how to make a low-cost and completely open-source laboratory-made air sampler that will be used for sample adsorption for thermal desorption-gas chromatography mass spectrometry (TD-GC/MS) analysis. It is well known that harmful gases cause bad effects on human bodies, so it is necessary to identify the types and amounts of gases in industrial sites. One of the most commonly used methods for gas sampling is to utilize a sorbent tube using an air sampler. Commercially available air samplers are expensive, typically priced between $1,000 and $2,000, and their design often cannot be modified to fit the experiment. To address these shortcomings, we have developed a do-it-yourself (DIY) air sampler that is not only cheap enough, but also completely open-source. Furthermore, the performance of the fabricated air sampler was validated in conjunction with TD-GC/MS for the analysis of volatile compounds.

DIY(Do It Yourself) 중심의 창작 활동이 확산되면서 일반 사용자들이 손쉽게 아이디어를 구체화 할 수 있는 환경이 마련되고 있다. 3D 프린터를 비롯한 디지털 기술과 도구의 대중화가 급속도로 진행되고 있는 반면, CNC 조각기의 경우 전문 지식의 부족과 복잡한 사용 절차로 인해 사용이 원활하지 않다. 이에 본 연구에서는 3D 형상 모델 파일만 선택하면 자동으로 가공이 가능한 CNC 조각기의 시스템을 개발하였다. 피삭재와 공구의 크기 및 종류를 제한하고, 생산성의 배제를 통해 공정 계획 및 공구경로 생성, 피삭재 고정, 피삭재 좌표계 파악을 자동화하였다. 그 결과 비숙련자도 혼자 충분히 사용 가능한 CNC 조각기의 시스템이 개발되었다. 이를 통해 기존보다 넓은 범위에서 다양한 사용자들이 사용할 수 있는 CNC 조각기의 발전이 기대된다.

Background: Personal protective equipment (PPE) has been designed in such a way to reduce accident rates. Unfortunately, existing PPE is rather ineffective as it is not able to provide warning signals when hazard is around. The integration of intelligent systems is envisaged to increase the efficiency of existing PPE. Methods: This project designed a safety vest incorporated with metal detectors which can provide immediate warning to the field workers when there is metal hazard around. This product has greater freedom of design via smart manufacturing as it involves the assembly of few commercially available parts into a single entity. Briefly, the metal detector is a do it yourself (DIY) kit, and the safety vest is purchasable from any local market. The DIY kit was connected to a copper coil and being sewed into the safety vest. Results: The metal detector induces beeping sound when there is metal hazard around. A total of 121 engineering students were introduced to the prototype before being requested to answer a survey associated with the design. Respondents have rated >3.00/5.00 for the design simplicity, ease of usage, and light weight. Meanwhile, respondents suggested that the design should be further improved by increasing the metal detection range. Conclusion: It is envisaged that the introduction of this smart safety vest will allow the workers to carry out their duties securely by reducing the accident rates. Particularly, such design is expected to reduce workplace accident especially during night time at construction sites where the visibility is low.

The purpose of this study is to set a relationship between intentional system and spatial orientation, and with space model in the human world to orient yourself is to present the basic spatial concepts. This is composed of parts of intentional system and spatial orientation on the research. Through the study of intentional system which is based on the orientation with Daniel Dennett's, it suggests the space-model that composed with aspects of intentionality and spatial elements. With space-model and judgement of spatial types, it makes relationship confirm between them. Through this process, following the results of this study were derived. First, intentional stance of space is the key for building knowledge and memories about space, and for identifying external environment images which are experienced in the senses of human. Second, changing the meaning from space to place makes horizons of space broader and creates a new sense of space with put the intentional orientation into the space. Third, this study can make confirm what the aspect of the space-schema-elements for orientation in space, serves as the presentation elements. This study leaps an old-view of the architectural customs about spatial orientation, and creates an opportunity to refine the newer concept of space. This concept of space is a basic essential for 'site-selection' and 'spot-catching' as an intentional system for spatial orientation and to establish a relationship with human beings in the world of his own orientation to the concept of space.
