Through this paper, all the provisions of the enforcement statutes stipulated in the Joseon's law code were investigated and major medical issues and interests in the Joseon Dynasty were analyzed. The characteristics of each period reviewed in the text are as follows. The early Joseon Dynasty is divided into three periods. First of all, Joseon filled the gap in the law with the active acceptance of the Ming Dynasty's law code, Daemyeongrul, which conformed to Confucian virtue. Next, the completion of Gyeonggukdaejeon was an opportunity to prepare the basis for Joseon's medical laws. Lastly, from the late 15th century to the 16th century, the existing medicine promotion measures and emphasis on hyangyak(domestic herb) continued. it can be said that Joseon's politicians needed a medical policy based on Confucian virtues and maintained state-led promotion policies, but on the other hand, there was no other alternative to try newly by reflecting the limitations and failures of the policy. The late Joseon Dynasty is also divided into three periods. First of all, the period from the late 16th century to the early 18th century was marked by the growth of families in technical positions. The era of King Yeongjo can be said to be the period of reorganization of medical related laws. Finally, the period after the late 18th century is a period of passive regulation and supplementation. Lastly, the revision of the actual medical law was not made or reflected in era of King Jeongjo. In the case of the early Joseon Dynasty, the policy shifted from state-led to families in technical positions. However, in the 19th century, the weakening of the royal authority led to the weakening of the overall administrative system of the country, and the pharmaceutical policy had to be limited.

Korea has passed the Act on the Integrated Control of Pollutant-Discharging Facilities in 2015, and the integrated environmental management under the BAT standard is underway. To summarize the nature of integrated environmental management, it is the regulation by the integration of the management of the multi-pollutant source and the technical standard of BATs. In general, in environmental economics, regulation-based on technical standards are known to be inefficient. This paper attempts to evaluate the efficiency of BAT standards from an economic point of view. A simple multi-pollutant model demonstrates that the inefficiency of the environmental tax with imperfect information in a single pollutant situation is amplified under multi-pollutant conditions. The simultaneous introduction of BAT and IPPC can be partially explained by this logic. It is also highlighted by the strengthening of BAT standards by EU, as a countermeasure to the potential deterioration of air quality caused by the change of effective environmental taxes accompanying the fuel and emission price changes.

Recently the consideration for occupants' security has been raised as very important design element from the fire by building's large sized, higher storied, and its compounded. But the domestic Laws regulated the predicative laws according to the technical standard which has no difference from the past domestic evacuation regulations. Therefore when big fire occurs, it is not enough to guarantee for occupants to escape safely. Specially since domestic escape relevant laws are divided into Architect relevant law and fire fighting relevant law, it has caused to bring various problems. So This study will show the problems of the evacuation regulation which is registrated in the Architect relevant law and fire fighting relevant law. And also later, when Architect escape relevant laws re-registrate, this study will be used as foundational materials.

In order to test the applicability of bunker-A in a diesel engine for small-fishing boat, the investigation of the engine performance and the exhaust emission was performed under various conditions of fuel property, intake air pressure and fuel temperature. It was also performed based on IMO NOx Technical code. At high load, the energy consumption rate of bunker-A was lower than that of diesel oil, and the characteristics of exhaust emission of bunker-A were similar to those, and NOx emission rates of both fuels satisfied the IMO NOx emission regulation limits. The energy consumption rate and characteristics of exhaust emission were improved as the intake air pressure was increased, but these were not improved remarkably as the temperature of bunker-A was heated. However, at low load the energy consumption rate, CO emission rate and HC emission rate of bunker-A were higher than those of diesel oil, but NOx emission rates of the fuels were about the same. In addition, at low load the energy consumption rate and CO emission rate of bunker-A were increased as the intake air pressure and the temperature were higher than normal conditions. Accordingly, it is thought that the use of bunker-A in a kind of test engine is possible at high load. On the other hand, it is thought that more research is needed to improve the combustion efficiency under low temperature and low load condition.

Metro subway construction is a field that requires a great deal of professional manpower. The aging of professionals has a negative impact on both productivity and health, owing to poor working environments, heavy lifting, underground work, and other factors. To address this issue, the government is progressively revising and enforcing health management law and regulation in the construction industry. Thus, the job stress and work ability of many professional subway construction workers, who are rapidly aging, are being analyzed to ensure their safety and improve their health. In this study, the Macpa stress index of Busan Metro Subway construction workers from Sasang to Hadan line was measured by using a Macpa measurement machine, and a work ability survey was conducted by using the questionnaire that was developed by the FIOH. The independent variables were age, years of service, job position, employment type, and occupation. While, the dependent variables were the Macpa stress index and work ability. The Kruskal-Wallis test was used because it was difficult to assume that the statistics of this study represented a normal distribution. The results showed that age, job position, and employment type affected Macpa stress index and revealed that as the age of the workers increased, their stress levels increased as well. Additionally, job position and employment type affected the work ability of the metro subway construction workers. In terms of job position, the technical engineers were under a lot of stress, and whereas the managers had the best work ability. The technical engineers were more stressed than the other workers because of a poor working environment. In terms of employment type, daily workers were under more stress and lower work ability than others.

Korean apparel industry is facing critical moment due to shortage of labor, wage increases and intensive competition among domestic manufactures. In addition, international production has been shifting to China and the other low-wage countries from established locations such as Korea, Hong Kong and Taiwan. Global sourcing has been received considerable attention since firms can enhance their competitive advantage as well as comparative advantage by coordinating their sourcing activities global]y. This studs regarded global sourcing as one of the strategic tools to achieve competitive advantage of Korean apparel firms, and explored the current status by literature reviews and series of in-depth interviews with managers of korean apparel firms. The findings of this study were as follows: 1) Due to geographical advantage, China was the most favored nation for outsourcing for domestic markers. However, exporting firms preferred Latin America (including Mexico) to take advantage of duties, quotas and geographical proximity to the US market. 2) In selecting the global sourcing country, productivity, technical ability, local government regulation, and culture were considered important. 3) Most Korean apparel firms sources production globally, and followed by raw materials and trims. 4) Cost and quality were the most important factors in deciding subcontractors, and experience, productivity, equipment and finances were the next concerns. Academic implications and future directions were suggested based on findings.
