In order to identify relationships between oral health management behavior and subjective oral health perception and oral acid production in small and medium industry workers, an examination on oral acid production and a survey were conducted. As a result, the subjective oral health status, which is subjective oral health perception, was found to have a significant effect on oral acid production, and the worse the subjective oral health status was, the higher the oral acid production was. As the subjective oral health perception is expected to be helpful for the development of industrial oral health programs to improve oral health of workers, organizational and institutional efforts for industrial oral health education will be necessary for improvement of subjective oral health perception of workers.

The purpose of this study was to classify the torso shape based on abdominal protrusion caused by changes in the physical characteristics of middle-aged women. This study analyzed 3D shape data of 401 females ranging in age from 40 to 59 years who participated in the 6th Size Korea project. Based on the Size Korea 3D measurement standard, 27 additional items such as height, protrusion, and angle were measured in the 3D scan data. Nine factors were extracted from the analysis of constituent factors of the torso: "vertical size of torso," "flatness and protrusion of abdomen," "torso front extrusion," "upper body height," "bust size and flatness," "size of belly and angle of lower abdomen," "hip length," "hip flatness," and "horizontal size of bust." As a result of the cluster analysis using these nine factors, the torsos of middle-aged women were classified into three types. Type 1 has upper abdominal deposition with a small and long upper body and an advanced abdomen; type 2 has lower abdominal deposition with a small and short torso and a small belly and hip flexion; and type 3 has central abdominal deposition with a big and long torso, large breasts, and protruding abdo¬men front. The middle-aged women were mostly distributed in Type 2. The above results will be useful as basic data for the development of clothing with improved fit to accommodate the changed physical characteristics of middle-aged women.

The regional infrastructure industries of Gwangyang City, the subject of this study, are Gwangyang Port and Gwangyang Steel Mill. Therefore, it is necessary to analyze the regional economic ripple effects of the port logistics industry in Gwangyang City. In this study, a multi-stage approach using the RW and the LQ methodology using the national input-output tables in 2015 and 2019 is used to prepare the regional interindustry analysis chart in Gwangyang City, and an exogenous demand induction model that reclassified the port logistics industry was applied. Through this, the purpose of this study was to provide policy implications by figuring out the regional economic ripple effects of the port logistics industry quantitatively in Gwangyang City. As a result of the analysis, the industries with high production inducement effect and forward/backward linkage effect of the port logistics industry in Gwangyang City were analyzed as manufacturing, transportation, land and air logistics sectors. And the industries in which the added value inducement effect and the employment inducement effect were analyzed as an industry related to the service industry. Therefore, it is necessary to prepare support measures to foster the port logistics industry as a way to promote these industries and revitalize the local economy of Gwangyang City. To this end, it is desirable to improve policies and systems for the vitalization of the Gwangyang port maritime cluster and provide various policy support for the port logistics industry in Gwangyang City. This study is meaningful in suggesting policy implications for the regional economy of Gwangyang City based on the results of exogenous analysis of the port logistics industry in small and medium-sized cities. However, It seems that further studies related to this will be needed in the future.

Small and medium-sized construction sites are most serious in Occupational Safety and Health in the construction industry. The safety consulting engineering has been launched, in 1995, to improve the safety environments and prevent serious injuries and fatalities accidents. The purpose of this study is to analyze the effect of the safety consulting engineering for small and medium-sized construction sites. This study conducts a number of interviews with experienced contractors, consulting engineers, etc. And the questionnaire survey was peformed with 111 respondents. This paper presents several improvements to increase the efficiency of the safety consulting system.

Recently, TFT LCD (thin film transistor liquid crystal display) manufacturing industry is more concerned with the ways of cleaning large TFT LCD´s with high pixed density than ever Ultrasonic cleaners with high frequencies like 1MHz (megasonic cleaners) are effective in removing very small particles without causing mechanical damage to the surface. In this study a megasonic cleaner for TFT LCD manufacturing process is developed and the performance is evaluated through experiments. The experimental results show that the developed magasonic cleaners is effective in removing very small particle from the LCD panel.

Competitive power is rapidly manufacture product required consumers. Therefore, modern industry have changed from small item many production to many item small production. rapid production is necessary thing at the product development. Thus, rapid prototyping is appeared. If the graphic model was made by CAD, the production can be made in short term. That provide what the part was directly tested by the worker. It provide believable data. This study is experiment on surface roughness of part at FDM

This paper reviewed the relationship among safety education/managerial factors, safety motivation and safety appliance, and the moderating effect of safety motivation. Based on the responses from 225 employees in small & medium manufacturing and construction industry, hierarchical regressional analysis showed that all education/managerial factors have positive relationships with safety motivation. Also, safety motivation has mediating effect between education/managerial factors(safety education, communication, system, precautionary activity) and safety appliance.

For the purpose of sped fying the character of Italian furniture industry, it's very important to analyse environmental aspects, in other word s, infrastructure of the furniture industry. These conditions that regional si tuation and circumstances, small and medium size of company depending upon the fami Iy oriented craftsman ship, roles of producers who are very keen on technical innovation and improvement, distribu tion structure and production status etc, are important factors to understand environmental characters of the furniture industry. Moreover, existence of various design languges according to design activities by architects un der that industrial structure is also regarded as the characters of that furniture industry. Through understanding the characters of Italian furniture industry and the drivig force of the growth, I would I ike to propose a role model for our domestic furniture industry.
