The purpose of this study is to evaluate the differences of recognition of the actual conditions, performances, problems and issues of the Direct Payment Program for Rural Landscape Conservation(DPPRLC) between interest groups who are residents, officials and experts. In the results of this study, there were differences in awareness of DPPRLC depending on interest groups and whether the program participation. It is determined to be caused the limitations of the program that the target district farmers recognised the program as a source of income and seldom act to manage the rural landscape except cultivating "landscape crops". Therefore, the efforts will be demanded to clarify and share the goals, contents of the project. The following measures are proposed in this study for the direction of improvement of DPPRLC: First, the various efforts are needed to overcome the differences on the interest group's recognition for goals, contents, performance of the Direct Payment Program for rural landscape conservation. Second, it is needed to conduct the program based on the rural landscape plan and participant's capabilities. Third, the various programs to attract voluntary participation from residents should be implemented. Forth, it demands the entrusted implementation to professional organizations to support resident's voluntary activities of surveying rural landscape resources, planning rural landscape conservation, execution of village landscape conservation, etc. Fifth, the various programs to strengthen participant's capabilities should be implemented.

This paper proposes a multiple-relay-assisted single side band (SSB) space frequency block code (SFBC) single carrier (SC)-frequency division multiple access (FDMA) system and measures the performance of SSB SFBC SC-FDMA transmission system with the signal-to-noise power ratio SNR) between relays and a destination station. As we know, the performance of relay-assisted transmission systems can be easily improved by re-transmitting to the destination station after applying block code to the recovered transmitted signals of relays. In this paper, the performance improvement of the relay-assisted SSB SC-FDMA system can be obtained without any significant increase of system computational complexity by implementing block code with the complex conjugates symmetric characteristic of SSB system. The simulation result shows that the SNR performance of the proposed multiple-relay-assisted SSB SFBC SC-FDMA system is about 4 dB better than the performance of the single-relay-assisted SSB SC-FDMA system at the symbol error rate of 10^-2.

This paper proposes a method of recognizing that a person doesn't put on a safety cap using image processing method in DSP(Digital Signal Processor). It processes inputted images by image input devices that equipped in a industrial settings. If the method recognizes a person that doesn't put on a safety cap, a system transfers relevant recognition result to a supervisor and takes proper measures. If an accident happens and someone doesn't put on a safety cap, additional casualities could be. Proposed method can nip additional casualties in the bud. To recognize that a person don't put on a safety cap, images are processed by object abstraction, removal of noise, decision of a thing or a person, abstraction of a head part in a image, recognizing whether a man puts on a safety cap using HSV color space or not, and so on. Image input and image process are processed by DSP. And C language-based codes are optimized by an eignefunction(Intrinsics) for speed improvement of algorithms.

This study analyzes the differences in definitions and concepts of terms used in the statistical indicators of fatal occupational injuries per 100,000 workers among countries included in the ILOSTAT data explorer. In addition, improvement measures focusing on the limitations in international comparison are proposed. Five countries-the Republic of Korea, Germany, Japan, United Kingdom, United States-- were comparatively analyzed. These countries were selected according to the significance of differences in their definitions of workplace injuries, workers, and compensation insurance, and their reporting systems. Considering these differences before directly comparing statistical indicators of fatal occupational injuries per 100,000 workers among countries is necessary because the range of comparison groups and the definition of fatal occupational injury are different for each country. While one can also compare trends by country, it is necessary to investigate beforehand whether the criteria and methods for processing statistics have changed. Misinterpretation can be minimized by properly understanding the process and limitations of fatal occupational statistical indicators that may differ from country to country.

This study examines the damage to the submarine's escape trunk hatch spring through microstructure analysis. The cause of the escape trunk's damage during the submarine's construction and its improvement measures were reviewed. To determine the cause of breakage of the escape trunk spring, samples were taken from the damaged product and analyzed for chemical composition, hardness, and microstructure. In particular, the breakage part of the spring was analyzed in-depth by using a scanning electron microscope to determine the cause of corrosion destruction. Finally, a spring shape design method was proposed through the investigation of the cause of spring breakage. In addition, a newly improved spring was produced by applying a nylon coating with excellent corrosion resistance and abrasion resistance. Applying to an actual submarine trunk hatch revealed that the coating peeling phenomenon due to the contact between the springs is significantly improved when the hatch is opened or closed compared to the existing products.

Flammable substances are often present in the raw materials of pharmaceutical products manufactured by pharmaceutical companies. In this case, an excessive amount of flammable substances is added to make an intermediate, and flammable substances that do not participate in the reaction are removed through filtration and drying steps. In addition, the flammable liquid separated in the filtration process is accumulated in the form of splash filling in the filtrate container. In this case, vapor and mist of flammable liquid are generated, which lowers the lower limit of explosion and minimum ignition energy, and increases the risk of fire and explosion due to complex charging. In this study, by analyzing fire accidents that occurred during the recent filtration process of pharmaceutical companies, it is proposed to prevent static electricity accumulation by measures of nitrogen supply facilities, capacity improvement, conductive filter fabric and so on.

Objectives: South Korea's occupational safety and health legislation appears on the surface to have stronger regulations than any other country, but it is criticized for having many problems when viewed from the perspective of the effectiveness and universality of these regulations. Therefore, it is necessary to consider the validity of the regulatory content and the methods for contract work in South Korea. Methods: The main issues in contract work are compared and analyzed in terms of the occupational safety and health laws systems in South Korea and other developed countries. Based on this, problems related to contract regulation are derived from the perspective of legal policy studies. In addition, effective improvement measures for the derived problems will be proposed. Results: Other developed countries impose obligations suitable for the status and role of persons who entrust work in consideration of the fact that they do not directly manage risks and in terms of the effectiveness of industrial accident prevention. These countries generally impose obligations such as management of facilities and machinery, cooperation and coordination with subcontractors, cooperation and coordination obligations between subcontractors, and guidance obligations on a person who entrusts a work. Conclusions: It is difficult to achieve effectiveness in preventing accidents with based on unreasonable regulations that do not conform to safety principles or legal theory. Regulations on contract work need to be converted to rational cogent regulations based on science and rationality, not ideology and emotion. To this end, the legal system for contract work must have international universality.

This study surveyed the perception of university students about employment in Small and Medium-sized Enterprises(SME) in the Chungbuk area to prepare improvement measures. In particular, the data were collected in descriptive questions along with the existing survey methods, and the perception of SME and decent work was identified using text-mining. As a result of the analysis, there are positive perceptions of jobs at SME such as various work experiences and low job competition rates, while there are generally many negative perceptions in pay, work and welfare. However, as a result of co-occurrence network analysis of responses to decent jobs, 'Information' was derived as a keyword. Currently, college students' negative perception of SME is affected by the lack of sufficient information, which needs to be improved first. To solve this problem, it was proposed to establish and operate a platform that can provide information on employment of SME and select necessary personnel.
