Small-scale production control systems for smart manufacturing are becoming increasingly necessary as the manufacturing industry seeks to maximize manufacturing efficiency as the demand for customized product production increases. Correspondingly, the development of an embedded system to realize this capability is becoming important. In this study, we developed an embedded system based on an open source system that is cheaper than a widely applied programmable logic controller (PLC)-based production control system that is easier to install, configure, and process than a conventional relay control panel. This embedded system is system is based on a low-power, high-performance Cortex M4 processor and can be applied to smart manufacturing. It is designed to improve the development environment and compatibility of existing PLCs, control small-scale production systems, and enable data collection through heterogeneous communication. The real-time response characteristics were confirmed through an operation test for input/output control and data collection, and it was confirmed that they can be used in industrial sites.

The purpose of this study was to propose a policy development plan for win-win growth between franchisor and franchisee by investigating success factors of win-win growth on the basis of the problems between franchisor and franchisee. There are many small scale franchise businesses in Korea that have not achieved an economy of scale compared to the developed countries. The conflicts between franchisor and franchisee have continued due to a lack of social trust which comes from an excessively high ratio of business failure and big firms' expansion into franchise business, then again, the perception of relations between the topdog and the underdog causes many problems. As franchise is the industry based on common people that helps service industry advance and competitiveness of the self-employed improve, it needs to be activated as the higher value-added business by promoting establishment of business and strengthening foundation of related industry. A matter of mutual cooperation and win-win growth between franchisor and franchisee is important not only for the sound development of franchise industry but also for the stable growth of nation's economy. Thus, this study suggested a policy development plan for win-win growth between franchisor and franchisee by analyzing success factor of win-win growth based on the problems between franchisor and franchisee. The results of the study provide the important strategic way towards mutual growth and maintaining cooperative relationship between franchisor and franchisee in Korean franchise industry.

To solve the serious problem of insufficient manpower in medium and small scaled companies, our country allows introduction of foreign manpower for 5 business types such as manufacture industry, service industry, etc. and there are 226,825 people who entered by employment license system(E-9) in Sep. 2013. However, according to the results of investigation "actual status and difficulties of foreign manpower's employment of medium and small scaled manufacturing companies" of KFTA in 2013, 36.4% of respondents responded that current scale of introducing foreign manpower is insufficient to solve difficulties of insufficient manpower in industrial world and 37.7% of them responded that the quarter of new employment is insufficient. So, they hope that current quarter system of foreign manpower can be abolished. Meanwhile, introduction scale of foreign manpower was decided by 53,000 people so as to solve enterprise difficulties in manpower and vitalize economics this year, but illegal aliens are 39,623, more than 17.5%, in Sep. 2013 after employment expiration. Therefore, it becomes serious social problem. Government displays various support businesses so that foreign workers after employment expiration can return to their homeland legally. This thesis intends to find measures to maintain royalty for our country and support their smooth resettlement through the analysis on homecoming support business of foreign workers.

The most recent issue of offshore plants that produce oil and gas are the decommissioning engineering of aged or discontinued platforms. There are many platforms that are being dismantled in the United States, Europe, and areas in Southeast Asia. In particular, more than 400 old platforms in Southeast Asia (Indonesia, Malaysia) are preparing to dismantle. They are spread out across Southeast Asia with a water level of 50 meters and small-scale of less than 10,000 tons. However, this offshore plant decommissioning market is a very suitable market for small and medium-sized shipyards in Korea to enter with their established equipment and engineers. Platform decommissioning is conducted according to decommissioning procedures. However, there are some difficulties in market advances as no developed case studies or process models are established on how platform structures and components are to be dismantled and how the dismantled material is to be reused and recycled. Therefore, this study presented domestic and foreign regulations on the reuse and recycling of oil and gas producing offshore plant platforms, case analyses on developed decommissioning engineering, platform reuse and recycling guidelines, and platform and pipeline decommissioning processes and methods.

The complex 2-dimensional movements of fish during an annual migration circuit were generated and simulated by a chaotic model of fish movement, which was expanded from a small-scale movement model. Fish migration was modeled as a neural network including stimuli, central decision-making, and output responses as variables. The input stimuli included physical stimuli (temperature, salinity, turbidity, flow), biotic factors (prey, predators, life cycle) and landmarks or navigational aids (sun, moon, weather), values of which were all normalized as ratios. By varying the amplitude and period coefficients of the klinokinesis index using chaotic equations, model results (i.e., spatial orientation patterns of migration through time) were represented as fish feeding, spawning, overwintering, and sheltering. Simulations using this model generated 2-dimesional annual movements of sea bream migration in the southern and western seas of the Korean Peninsula. This model of object-oriented and large-scale fish migration produced complicated and sensitive migratory movements by varying both the klinokinesis coefficients (e.g., the amplitude and period of the physiological month) and the angular variables within chaotic equations.

Korea has been rapidly industrialized during the past 35 years. During this period, Korea has emphasized only production and workers health has been ignored. Workers are most frequently exposed to organic vapors, such as thinners. This study was performed to evaluate worker exposures to organic solvents by size and type of industry. Results are summarized below. Workers were exposed to mixtures of toluene, xylenes, trichloroethylene, n-hexane, acetone, methanol, n-butanol, n-butyl acetate, and MIBK. Considering additive effects of the compounds, exposure indices (EIs) were calculated. It was found that worker exposures to organic solvents were highest in small industries and lowest in large industries. During a day shift, the highest exposure was indicated 3 - 5 p.m. in the afternoon. Workers in small industries had potential exposures exceeding permissible exposure limits for organic solvents. Local exhuast systems were inappropriate and respiratory protective devices were not supplied to the workers in small industries. Neither program for safe use and storage of toxic materials nor program for respirators was found in any of the plants investigated. Based on the results of the study, workers of small scale industries should be considered first in industrial health.
