The unit modular construction system is a building technique in which unit modules are manufactured at a factory and then assembled at the construction site. It has many benefits, including reduction of the construction period and improvement in quality. For this reason, it is utilized for various purposes in Japan and England. While it has been introduced in Korea, there have been few Korean studies conducted on the unit modular system. In particular, little research has been done on the method of safely fixating the unit modules to a truck. Therefore, this study reviewed the fixation methods of unit modules for transport, analyzed the problems, and designed a fixation device for unit modules. In addition, a device for the fixation of unit modules to a truck was developed, and a structural simulation was implemented for a safety test by considering the maximum stress generated during the transport of the unit modules fixed on a truck. When the device for the fixation of unit modules is manufactured based on the results of the structural simulation done in this study, it is expected to aid the development of a more practical fixation device for unit modules.

Recently, it was under an obligation to install the VOCs recycling unit in the cleaners and the gas station to prevent from discharging VOCs emitted from the cleaners and the gas station. The objectives of this study was to investigate the VOCs recycling unit used thermoelectric module to recycle the organic solvent from the cleaners and after washing. The traditional way was the use of the VOCs recycling unit with the compressor. But the recycling unit has many weak points , noise, size, danger of fire, additional pollution and so on. In order to improve these weak points, it was developed the new VOCs recycling unit using the thermoelectric module through this study. The cooling block with 32 thermoelectric module was applied to cool the hot VOCs where comes to occur from the dryer in high temperature condition. Also a water-cooled equipment was used to remove the heat from the hot surface of thermoelectric module. The experimental results from new VOCs recycling unit shows that the maximum recovery rate of the unit was 83.2 % and the recycled VOCs' purity was 98 % or more. And the noise problem was solved by applying the thermoelectic module to the VOCs recycling unit.

The unit modular method is one in which unit modules are prefabricated at a factory and then constructed at a construction site. That is why an important process, transporting unit module, is added in this method. The purpose of this study is to analyse the load for transporting unit module. The results of the analysis of the driving experimental runs revealed that a maximum load of 15 kN was applied on adapter block type A and a maximum load of 25 kN on adapter block type B. These loads were recorded at the points in the road test when the low-bed trailer was driving through unstable sections of the test such as stopping, restarting, passing over a speed bump or taking a left turn at speed.

This research is to suggest a unit-module plan of cross stacking method for design diversity of modular housing. In this study, we analyzed cases of the domestic and overseas modular construction which applied with the cross stacking method. Through case studies, we confirmed that the method was suitable for diverse design plan of modular housing. In addition, we performed 3D modeling, using framed modules of dormitory for foreigners and public dormitory for university students. Through this process, we have identified constructional and structural problems. Futhermore, we derived solutions for the problems and also for detailed unit-module plan of the cross stacking method. Thus, we made a model of unit-module plan to verify its utility and then we confirmed that it is very useful to the cross stacking method for design diversity of modular housing.

PLC는 공장자동화 설계에서 가장 많이 사용되고 있으며, PLC 언어에 대한 연구도 활발히 이루어지고 있다. 본 논문에서는 PLC를 사용한 공장 자동화 설계에서 제어하고자 하는 출력 기기의 수가 증가되었을 때 출력을 확장하는 방법을 제안한다. 기본 베이스에 출력 유닛을 더 이상 장착할 수 없는 상태에서 출력 점수를 $2{\sim}3$점 확장하고자 한다면, 증설베이스와 파워서플라이, 증설케이블 및 출력 유닛을 별도로 장착하여야 한다. 그러면 비용이 상당히 추가되어야 한다. 본 논문에서는 출력을 소량으로 확장하는 방법을 제안한다. 즉, 출력 유닛의 접점을 입력받아 디코딩하는 확장모듈과 인코딩 및 디코딩하여 최종 출력접점으로 확장하는 프로그램 모듈을 설계하고, 실험을 통해 그의 타당성을 확인하였다. PLC is the most widely utilized among many sorts of existing controller for the design of process control system, and study about a PLC language is performed actively. In this paper, we proposed the method that we increase an output points when increased of the output machine which is going to control it in the FA design that used PLC. Output point is going to be extended with 2-3 points in the state that cannot equip output unit in basic base any more. Then an extension base, a power supply, an extension cable and an output unit must be equipped particularly. Then a cost must be added very much. This paper propose the method which extended an output in a small quantity. We designed the expansion unit that received the points of output unit and decoded the signal and the program module that finally extended output points by encoding and decoding, and we confirmed his feasibility through a experiment.

조남주 ( Joh Namjoo ) 한국공간디자인학회 2020 한국공간디자인학회논문집 Vol.15 No.8

(Background and Purpose) An enormous increase in the number of single-person households and the rapid change in the consumption trends in Korea, different from the consumption patterns of multi-person households, have led to a new type of urban living spaces, such as one-room households and officetels (multipurpose buildings with both commercial and residential units). An increase in income, improvement in education, an increase in the female economic activity ratio, delayed marriages, spread of individualism, and aging society are major factors of the demand for built-in spaces. This study aimed to suggest how to improve the expandability of small-unit spaces and achieve the fulfillment of residents’ activities by proposing a modular system furniture design. (Method) First, to optimize the utilization of the limited physical space in a small unit, the variability of furniture should be provided. Second, users are to be allowed to optimize their movement, and third, dead space should to be minimized. A folding mechanism was applied to beds, desks, and wardrobes, and frame units and shelving were modularized to present a system that could be expanded depending on the space size and user demand. (Results) The development direction of the furniture design proposed in this study was divided into three equal parts based on the 1950 mm bed length, and the width of 700 mm was standardized as one module unit. The basic type of space-saving storage furniture module system was planned with the wardrobe-bed-desk/table as essential items, as well as the incorporating of the folding function with desks and tables, along with installing the folding hardware. The mechanism of the T-type connector that links the steel frame and the panel was applied to enable door mounting. The proposed module types were classified as the compact type (A), general type (B), and extended type (C), and a design that extended from the basic item configuration to module configuration for leisure use was proposed as an example. It was a representative composition of three overall sizes obtained by calculating the average value of various house sizes based on the size of urban living houses, and it was planned to adjust the size according to the choice of storage cabinets. Elevation design was performed by combining the extended module types with a width of at least 3300 mm to maximum 5500 mm, and a total of nine items such as wardrobe-bed-desk/table-TV stand-storage space (bookcase, drawer cabinet, box, etc.)-leisure space module. (Conclusion) This study provided an understanding of the main perspectives of the modular system of storage furniture suitable for small-unit spaces, and suggested the direction from the social and cultural aspects of the change of Korean single-person households’ residential spaces and the creation of new industries. Accordingly, this study may serve as a guideline for improving the R&D capabilities of domestic companies that will be able to compete with global companies in related industries, as well as establishing public policy directions.
