This paper examines the shift to service economy in the developed countries including Korea and analyzes whether Baumol's cost disease hypothesis could explain the labor productivity growth in the developed countries even though the share of service industry is rising rapidly. We have found the following results: First, the shift to service economy is widely observed in the developed countries. Second, the productivity gap between manufacturing and service industry is widening as a result of stagnant productivity growth in service industry. Third, however, the productivity in the whole economy is still growing because of the large productivity differences among the sub-industries in service industry. Fourth, we have found that the productivities of some service industries, such as finance, communication, business service, etc., are almost same or larger than the productivity of manufacturing industry. From this fact it is likely that the productivity of the whole economy could grow in spite of the stagnant productivity growth in service industry.

The purpose of this study is to evaluate the productivity of elderly employees over 60 years old and to analyze factors that directly or indirectly affect the productivity of elderly employees, based on empirical facts of HR managers. As a result, the factors that have a positive effect on the productivity of elderly employees were attitude and professionalism. The decline in physical capacity due to aging was recognized as a key factor that negatively affected the productivity evaluation of elderly employees. Among the management strategies to improve the work performance, it has been shown that work placement or job redesign according to physical competency contributes to improving the productivity of elderly employees. Also, providing safety education and communication opportunities among workers has a positive effect on productivity improvement. The results of this study suggest that it is important to improve worker productivity by arranging older workers' work experience to be able to demonstrate their accumulated career and expertise and to create a working environment that takes into account physical competence.

In the era of the fourth industrial revolution, many production plants are gradually evolving into smart factories that apply information and communication technology to manufacturing, distribution, production, and quality management. The conversion from conventional factories to smart factories has resulted in the automation of production sites using the internet and the internet of things (IoT) technology. Thus, labor-intensive production can easily collect necessary information. However, implementing a smart factory required a significant amount of time, effort, and money. In particular, labor-intensive production industries are not automated, and productivity is determined by human skill. A representative industry of such industries is sewing the industry. In the sewing industry, wherein productivity is determined by the operator's skills. This study suggests that production performance, inventory management and product delivery of the sewing industries can be managed efficiently with existing production method by using smart buttons incorporating IoT functions, without using automated machinery.

Recently, the world is facing many difficulties in all areas as a result of price instability and the Russian-Ukraine war. Personally, as many jobs disappear, household income is declining sharply. In particular, the possibility of such bankruptcies is relatively increasing in small and medium-sized enterprises (SMEs), and it is highly likely that this will continue for the time being. In this situation, countries around the world are continuously making efforts to improve corporate productivity. In Korea, the smart factory support project implemented by the Smart Manufacturing Innovation Promotion Team has been continuously promoted for the past several years, providing opportunities for SMEs in need to improve productivity and change the corporate structure. In this study, the current status of smart factory promotion at home and abroad was examined, and problems and improvement measures were studied for the insufficient efficiency in the smart factory promotion system implemented in Korea.

This Study is to show the impact of IT capital stock accumulation on the total factor productivity in 9 industries during 1980 through 2000. We construct the If capital stock using input and output table provided by Bank of Korea (2000). Using sequence testing methodologies, we investigate the nonstationary characteristics of the relevant data and test the cointegration relationship between total factor productivity and IT capital stock. Over the past two decades, IT capital stock contributed between 0.19 to 0.07 percentage point per IT capital stock on total factor productivity. Our empirical results, therefore, do not support Solow's IT paradox in using the long period panel data case in Korea.

Highly efficient and environmentally friendly mechanical process was developed for the higher recovery rate and productivity in the recycling of waste jelly-filled communication cables. Only the simplest mechanical method was designed and built for a continuous process, further proved experimentally along with the addition of several parts such as brush-type rollers and scrappers. In this process, the recovery rate and productivity were 98% and 55 Kg/hr respectively. This process is thought to be simple but highly advanced method for the commercialization of green process.

It is generally defined that the trust between members are relayed on the belief of ability and support. The purpose of this study is to make sure that participative decision making effects on productivity of group based on that cooperative relationship could bring the productive improvement. As the results, we could figure out that satisfiable rate of performance feedback and open communication are related with the productivity Especially, an administrative group based on the mutual trust, can meet the level of customer's satisfaction and cultural multiplicity. Setting up the mutual trust is to maximize the ability of members and to derive the motivation of working concentration.

UV-curable resin has the properties of quick-drying, thigh productivity at low temperature, energy savint, space saving, solventless, non-polluting and low-stinking, and thus, UV-curing system has been widely used in the fields of printing inks, adhesives, paints and coating agents. This study has been executed to micro-patterning used UV-curable resin, The micro-patterning properties of this photoresist were investigated under irradiation of UV light low pressure mercury lamp. When the exposed photoresist film was developed by pure water developer, the resolution of this photoresist was about 50$\mu\textrm{m}$.

In this paper, we added that developed communication control system between the PLC of pressure machine and the control computer, and developed a new protocol in order to communicate between the PLC signal of pressure machine and the control computer. This communication control systems play an important role in transforming the PLC vendor self-interface type and between computer and PLC. This system has PLC access function to control computer on the backbone network, and then could be operated by PLC through this system. The benefits we can obtain by developing this communication control systems are as follows; First, we can improve the quality of goods and the management of materials using the communication network and then implement the centralization management. Second, we can decrease manpower for production. Finally, we can maximize the company's profit with the increasing productivity by supervising the equipment wrong workings in the central.

In communication protocol design, it is important that design procedure is simple and result protocol must be correct. This paper presents a communication protocol synth-sizing algorithm, which enhances productivity of protocol design, using CFSM. CFSM is defined as extended FSM for representing protocol information and simplification. In this method protocol designer descripts only one communication machine with out error consideration using FSM, then two communication machine M' and N' are generated. And then transformation rules for error-recovery converts M' and N' to EM' and EN' which are logically correct.
