Purpose: This study analyzed the relationship between working hours and the occurrence of industrial disasters based on manufacturing businesses that are members of Federation of Korean Trade Unions.Methods: Repliers were managers of the safety & health department in the union, and 215 surveys out of 300 businesses that agreed to participate in the research were analyzed. Results: 94 out of 300 companies, which counted for 43.7%, replied to have experienced industrial disasters. 56 of those (59.6%) had less than 52 working hours per week, and 38 companies (40.4%) had more than 52 working hours per week. 109 companies, which counted for 50.7%, did not have an incident of industrial disaster. Companies with an average of more than 52 hours of working hours per week were shown to have a 2.29 times (95% CI 1.08~4.87) higher possibility of having industrial disasters than those with less than 52 hours of working hours. Conclusion: As the study showed that industrial disasters were more likely to occur in businesses with working hours longer than 52 hours, ways to reduce working hours need to be developed and various safety measures need to be taken to prevent industrial disasters in case workers are undergoing long working hours.

We have compared and analyzed the definition of medical devices, classification, who treats, controls and sales the spectacle frames in South Korea, USA and European Union in this paper. South Korea classifies the spectacle frames as an industrial products while EU and USA regards it them as the medical devices. Sunglasses are industrial products in South Korea and EU but they are still the medical devices in USA. Assignment of spectacle frames and sunglasses as an industrial products could bring into several problems. Restricted classification of medical devices on spectacle frames and sunglasses will resolve the problem mentioned.

Background: Salmonella enteritidis (SE) was the main cause of the pandemic of foodborne salmonellosis. The surface of eggs' shells can be contaminated with this bacterium; however, washing them with sodium hypochlorite solution not only reduces their flavor but also heavily impacts the environment. An alternative to this is surface sterilization using low-energy electron beam. It is known that irradiation with 1 kGy resulted in a significant 3.9 log reduction (reduction factor of 10,000) in detectable SE on the shell. FAO/IAEA/WHO indicates irradiation of any food commodity up to an overall average dose of 10 kGy presents no toxicological hazard. On the other hand, the Food and Drug Administration has deemed a dose of up to 3 kGy is allowable for eggs. However, the maximum dose permitted to be absorbed by an edible part (i.e., internal dose) is 0.1 Gy in Japan and 0.5 Gy in European Union. Materials and Methods: The electron beam (EB) depth dose distribution in the eggshell was calculated by the Monte Carlo method. The internal dose was also estimated by Monte Carlo simulation and experimentation. Results and Discussion: The EB depth dose distribution for the eggshells indicated that acceleration voltages between 80 and 200 kV were optimal for eggshell sterilization. It was also found that acceleration voltages between 80 and 150 kV were suitable for reducing the internal dose to ≤ 0.10 Gy. Conclusion: The optimum irradiative conditions for sterilizing only eggshells with an EB were between 80 and 150 kV.

This study examined chemical characterization in commercial dark-fleshed fish (mackerel Scomber japonicus, Japanese Spanish mackerel Scomberomorus niphonius, and Pacific herring Clupea pallasii) to determine their suitability for use as raw materials for seafood products. The volatile basic nitrogen (VBN), heavy metal, radioactivity, polychlorinated biphenyl (PCBs), benzo[a]pyrene, and histamine concentrations were measured. The VBN in all of the dark-fleshed fish was less than 20 mg/100 g, which is the limit for raw materials for seafood processing. Except for mackerel based on the lead (Pb) standards of the European Union (EU), Taiwan, and CODEX, and all fish based on the cadmium (Cd) standards for China and the EU, the commercial dark-fleshed fish were free from total mercury (Hg), Pb, and Cd based on domestic and foreign standards. The radioactivity, polychlorinated biphenyl (PCB), benzo[a]pyrene, and histamine concentrations of the commercial dark-fleshed fish all adhered to the domestic and foreign standards. The commercial dark-fleshed fish tested could all be used as raw materials for seafood products, except for some exported products.

This thesis examined the main revolution trend of Chinese engineering education system which is closely related to the demand of the industrial world. The reasons for which China tried to revolutionize engineering education were as follows ; firstly, the lack of high-qualified and professionalized man power in the industrial world. Secondly, the rupture in the age structure and thirdly, graduate students' insufficient ability to adapt to the industrial companies. These situation had been influenced by professional education after the fashion of the Soviet Union and the Cultural Revolution. Thus, since 1980s, government have extended man power supply through various ways and maintained equilibrium between supply and demand within the industrial world. Also, government began to retrian the existing engineers, magnify the regular number in college students of science and engineering and treat an experienced man favorably in graduate schools. The State Education Commission leaded in searching for the ways to train engineers and testing the master of engineering training system. As an essay at reform, many attempts will be tried ; bringing-up excellent students, the system of multi-degrees, field work, bachelor-master integration management, the system of master and doctor by thesis, strengthening educational-industrial cooperation, experimental school, adult school, and local school. Until 21c to come, this trend will be accelerated on.

This study examines how the difference in trade openness across manufacturing industries in Korea affects firm's employment strategies and industrial relations, utilizing the Korean establishment panel data. In terms of firm's employment strategy, it is found that trade openness is not associated with a particular employment strategy such as labor cost saving strategy or innovation strategy. This result is consistent with the previous findings that trade liberalization merely affects wages and employment. Moreover, this result disproves, at least for the Korean manufacturing, a general belief that when the domestic market is opened to foreign competition, firms will adopt and rely on labor cost saving strategy intensely. The obtained result concerning the relationship between trade openness and industrial relations is more interesting and informative. It is found that trade openness is positively associated with cooperative industrial relations. Furthermore, the positive relationship is reenforced when the establishment is unionized. This implies that management and union cooperate when they are faced with increased foreign competition as a result of trade liberalization.

In 2007, KSLV(Korea Small Launching Vehicle) that we made at Goheung National Space Center is going to launch and promotes of our space exploration systematically and 'Space Exploration Promotion Act' was enter into force. 'Space Exploration Promotion Act' article 3, section 1, as is prescribing "Korean government keeps the space treaties contracted with other countries and international organizations and pursues after peaceful uses of outer space." The representative international treaties are Outer Space Treaty (1967) and Liability Convention (1972) etc. In Liability convention article 2, "A launching State shall be absolutely liable to pay compensation for damage caused by its space object on the surface of the earth or to aircraft in flight. The important content of the art. 2 is the responsible entity is the 'State' not the 'Company'. According by Korean Space Exploration Act art. 14, person who launches space objects according to art. 8 and art. 11 must bear the liability for damages owing to space accidents of the space objects. Could Korean government apply the Products Liability Act which is enter into force from July 1, 2002 to space launching person? And what is the contact type between Korea Aerospace Research Institute(KARl) and Russia manufacturer. Is that a Co-Development contract or Licence Product contract? And there is no exemption clause to waive the Russia manufacturer's liability which we could find it from other similar contract condition. If there is no exemption clause to the Russia manufacturer, could we apply the Korean Products Liability Act to Russia one? The most important legal point is whether we could apply the Korean Products Liability Act to the main component company. According by the art. 17 of the contract between KARl and the company, KARl already apply the Products Liability Act to the main component company. For reference, we need to examine the Appalachian Insurance co. v. McDonnell Douglas case, this case is that long distance electricity communication satellite of Western Union Telegraph company possessions fails on track entry. In Western Union's insurance company supplied to Western Union with insurance of $ 105 millions, which has the satellite regard as entirely damage. Five insurance companies -Appalachian insurance company, Commonwealth insurance company, Industrial Indemnity, Mutual Marine Office, Northbrook Excess & Surplus insurance company- went to court against McDonnell Douglases, Morton Thiokol and Hitco company to inquire for fault and strict liability of product. By the Appalachian Insurance co. v. McDonnell Douglas case, KARl should waiver the main component's product liability burden. And we could study the possibility of the adapt 'Government Contractor Defense' theory to the main component company.

Five elements that form all things have been symbolized in that they are indispensable elements in human life. Moreover, each unique energy has been used to explain the existence of all creation and the origin of action. The theory of five elements can be changed and utilized into various forms, including co-existence and conflict of five elements, five elements itself, the combination of Ganji five elements, Wangsanhyususa(旺相休囚死), five elements and Yin-yang. Especially, 『Hyupgiltongui Bonwon chapter one covers five elements, five elements of Ganji, seasonal use of five elements, prosperity and decline of five elements depending on seasons, Union of 3 elements among Twelve Zodiac Signs(三合), Union of two elements among Twelve Zodiac Signs(六合), changes of Cheongan 5hab. Therefore, if you analyze and utilize them, you can tell someone's fortune by theory of five elements only and read fortune in detail by combining it with other theories.

Purpose - The objective of the current research is to explore success factors of the 'Night Markets' in Korea. Unlike other countries, where the markets are culturally established based upon various socioeconomic factors, the night markets are relatively new phenomena in Korea and are created by the government's support. Since the first introduction in 2011, now there are 34 Night Markets that are operating or are in the process of operation. Some of them attract nearly 100,000 customers a day, while some are discontinued shortly after the introduction due to lack of visitors. Its influence on the customers' behavioral motives of engaging in various activities in the night markets is increasing. However, because of its brief history in Korea, not much of research has cast attention on them. It is imperative to figure out the success factors of the night markets, so that other night markets can learn the secret of successful operation of the markets. Research design, data, and methodology - The research is based upon both qualitative and quantitative data. Data are collected from multiples levels of the night market related parties. Four groups are chosen: customers, night market sellers, sellers' union and government officers who are in charge of the market. Conventional survey formats are employed for customers and night market sellers. For night market union and government officers, survey and in-depth focus group interview methods are applied. Of the night markets in operation, commonalities of successful or well established ones are elaborated. Results - Night Market operation success factor are sought utilizing Porter's The Competitive Advantage of Nations model (1990). Results are shown that successful night markets commonly have satisfactory 'Factor Conditions.' Specifically, established night markets have either nearby big cities or tourist attractions in common. While these have fair 'Firm Strategy/structure/rivalry,' and 'Related and supporting industries,' they commonly demonstrate weakness in 'Demand conditions.' Conclusions - A successful night market incurs new customers not only to the market itself but also to the traditional periodical market the night markets are within. Government support to the night market can be justified where the circulation of new customer to the night market and the night market to the periodical market mechanism is in effective.
