  • The airspace has to be designed considering the flight safety and economic efficiency of aircraft operators. The International Civil Aviation Organization(ICAO) published standards and recommended practices for safe design of the airspace. Each contracting country must follow the ICAO standards in designing the airspace for the utilization of civil aviation. Normally each member establishes its own standards and national aviation law for the safe and efficient design of the airspace, regarding the ICAO standards. However, our government has not developed yet clear and detailed standards and regulation system for airspace design. This might lead to aviation accidents and disputes between operators of aviation system This study is to review the characteristics of ICAO standards and a legal problem related to application of international standards for airspace design. Specifically this research analyzed the case of airspace design and operation of a domestic airport. The results of analysis are as follow: (1) per the safety of civil aviation, it is very required to establish national regulation system to follow ICAO standards in designing airspace, (2) It is also necessary to establish separate procedure for civil aircraft in military air base, when the aerodrome is co-used by military and civil aircraft. If the same procedure for military aircraft is applied to civil aircraft, it is necessary to make clear what the design concept is, (3) and the differences from ICAO standards have to be publicly known.

  • Two species of demersal fish, Liparis tessellates (cubed snailfish) and Hemitripterus villosus (shaggy sea raven), were investigated in relation to seasonal chemical composition. Total fat contents of the two fish were very low and were not appreciably different throughout the year, whereas their fatty acid compositions were significantly different depending on season. Noticeable changes in the moisture and protein contents in the two fishes were observed before and after spawning. Cubed snailfish showed relatively high amounts of total amino acids and free amino acids during summer months, whereas the levels of those in shaggy sea raven remained relatively unchanged throughout the year. Regardless of season, the major fatty acid of the two fishes was palmitic acid and most of polyunsaturated fatty acids (PUFAs) were n-3 PUFAs. Lead was over the legislative limit in some samples of the two fishes.

  • In the present study, mec complex typing and SCCmec typing were performed to analyze the molecular genetic characteristics of 20 methicillin-resistant Staphylococcus aureus (MRSA) strains isolated from clinical specimens and 4 strains isolated from the ICU environments of secondary medical institutions in a Chungnam province, Korea, from June to July of 2017. Among a total of 20 MRSA strains isolated from clinical specimens, 8 cases (40%) were SCCmec type II, one case (5%) was SCCmec type IVa, and 11 cases (55%) were not-typeable in SCCmec type analysis. Among 4 MRSA isolates from the ICU environment, one strain did not have the mecA gene and 3 strains were typed as SCCmec types II, III, and IVa, respectively. Data from the present study showed that the origin of MRSA isolated from the clinical specimens was different from those from the ICU environment in most cases but the origin was concordant in one case. In this case, MRSA might be transmitted by healthcare workers to the ICU environment. Further study with a large number of cases and other hospital infection-related microorganisms will be needed. This continuous follow-up study might provide useful information on infection control in medical institutions.

  • This study was to investigate the recognition level of food safety from high school students(264 male, 276 female) in Chuncheon area using questionnaires. The results of the survey are summarized as follows : Regarding the general consciousness of the conditions of food safety, the proportion of the students who worry about it is higher, while 40.0% respond they are not concerned with it. The information pertinent to food safety was usually acquired from the mass media. As a fundamental reason responsible for the food safety accidents, they pointed out deficient sense of responsibility of the personnels who produce, distribute, and sell food products. As the most problematic materials threatening food safety, they pointed out heavy metals(24.8%), and subsequent responses were environmental hormones(24.4%), food additives(17.0%). The foods, for which they are most concerned about residual pesticides, were vegetables and fruits. High proportion of the students perceived that agricultural products are not safe from residual pesticides, and most of the students(92.4%) thought that residual pesticides are bad for their health. The examination on the food safety influenced by heavy metals reveals that 87.4% of the students thought the materials do influence food safety. As the food kind that is likely to be most polluted by heavy metals, they pointed out fishery products. The highest concern about processed food stuffs was the food additives. Most of the students thought that the containers of processed foods may be toxical. 25% of the students are more seriously considering food safety when they buy foods. High proportion of the students who responded they confirm safety-related matters at the time of food purchase thought much of food safety, while high proportion of those who didn't confirm those matters lay a great importance on the taste.

  • In this study, a questionnaires survey was administered to Korean and Japanese junior high school science teachers in the capital area to investigate the extents of Science-Technology-Society(STS) education practiced in science classroom. The responses of 69 Korean teachers and 33 Japanese teachers were analysed. The results showed that most of teachers in both country knew well about the meaning and the purpose of STS education. Also they realized the needs of applying the STS education in science class and had wills to do it. However, only about a half of teachers - more than a half of Japanese and less than a half of Korean - were practicing the STS related subjects, activities and assessments in the class. Teachers in both country responded that their science textbooks did not contain enough amounts of STS related contents and other STS education materials available were not much. Therefore, it is needed to include more STS related contents in the science textbooks and to develop various STS education materials and circulate them as well as to establish adequate teaching and assessment methods for STS education. Also activating teachers' meetings to circulate the informations and materials and improving the school environments are recommended.
