To evaluate the potential risk associated with zoonotic ascarid eggs in educational facilities and public playground in Seoul city, the sand samples collected from April to December in 2011 were examined with a fecal flotation method. Of 5,066 sand samples from 1,367 playgrounds tested, 12 sands from 12 places (0.88%) had ascarid eggs. Sand samples in educational facilities were more contaminated (10/870, 1.15%) with the parasite eggs than those of public playground area (2/497, 0.4%). Fisher's exact tests were used to make pairwise comparisons between which locations were more or less similar with regard to levels of contamination. We didn't find significantly different from one another. Most ascarid eggs detected were found in the Spring. Through this study, we hope to raise awareness of contamination of playgrounds by potentially infectious ascarid ova.

Taking into account the globalization of the economy and the intensification of European integration processes, it has been proved that an important part of evaluating the effectiveness of activity of public sector enterprises should be a comparative analysis of the overall operation environment, namely public procurement, economic environment and tax policy, with the relevant systems of other countries of the world. The indicators and components of international ratings "Doing Business", "Paying Taxes", "Benchmarking Public Procurement" have been studied. Different groups of indicators forming "Doing Business" and "Paying Taxes" in the context of the impact on public sector enterprises have been identified: those which fully comply with the need to evaluate the operating environment of public sector enterprises and those which should be used with restrictions, regarding the peculiarities of creating and functioning of public sector enterprises. A comparative analysis of the place of Ukraine, Lithuania and Slovenia among other countries of the world in accordance with the international rankings of "Doing Business", "Paying Taxes", "Benchmarking Public Procurement" have been made. It has been substantiated that the results of such comparative analysis will allow identifying risk areas, and relevant information can be used in developing of recommendations for improving the effectiveness of activity of public sector enterprises.

Objectives: This study was carried out to provide safe seafood to the public through simultaneous analysis rapid inspections for residual veterinary drugs in 150 fishery products in 2016. Methods: Quinolones (9), Sulfonamides (14), Penicillins (2), Cephalosporins (3), Tetracyclines (4), Macrolides (4), Lincosamides (2), Pleuromutilin (1), Phenicols (4), benzylpyrimidines (2), Others (1) Malachite green (2), and Melamine (1) were analyzed for 49 species using by HPLC and HPLC-MSMS. Results: There were six unsuitable samples, five among fish and one for crustaceans. Within the standard detection were five fish. The antibiotics found were Quinolones (50%), Tetracyclines (33%) and Penicillins (17%). Conclusions: As a result of the experiment, there were six unsuitable samples, five for fish and one for crustaceans. The most prevalent antibiotics were Quinolones. The quinolone antibiotics are highly persistent in fish tissues, so they require more time than the withdrawal period for other common veterinary drugs. Careful attention is required when they are used in fish farms.

본 연구는 취나물, 고춧잎, 열무를 대상으로 건조에 따른 procymidone, diazinon의 잔류량의 경시적 변화를 연구할 목적으로 수행되었다. 실내풍건 방법으로 건조하는 경우, procymidone, diazinon의 잔류량이 증가하지만 수분함량의 감량을 고려하여 보정하면 $10{\sim}83%$ 감소하였고, 열풍건조 방법으로 건조하는 경우도 농약 잔류량은 증가하여도 수분함량의 감량을 고려하여 보정하면 $44{\sim}71%$ 감소하였다. 이 결과에 의하면, 건조에 의하여, 수분 보정한 농약잔류량이 대부분 감소하므로 건조농산물을 판정함에 있어 단순히 신선농산물의 기준에서 수분함량의 감량을 고려하여 기준 적용할 것이 아니라 건조과정 중 농약잔류량에 영향을 미치는 여러 요인을 고려한 추가연구가 필요하다고 판단된다.

농산물 중 잔류농약을 보다 쉽고 효율적으로 분석 할 수 있는 다성분 동시분석 방법에 따라서 UPLC-PDA을 이용하여 기기조건에 따른 검출한계 및 정량한계를 식품별 최저 MRL과 비교하여 유효성을 알아보고 회수율을 통하여 방법의 재현성을 조사한 결과 다음과 같다. 41종의 농약에 대한 검량선은 직선성이 우수하였으며 검출한계 $0.005{\sim}0.109mg/kg$으로 나타났으며 정량한계 는 $0.018{\sim}0.363ppm$으로 나타났다. Cycloprothrin 등의 경우처럼 검출기의 감응도가 최저 MRL 기준을 초과하는 농약에 대한 보완으로는 검출감도가보다 우수한 UV 검출기 등의 병행 활용이 필요하다. 회수율에 따른 재현성은 쌀의 경우 첨가 농도 0.4 mg/kg 일때 $62.09{\sim}99.58%$로 편차범위는 $1.03{\sim}13.92%$ 얻을 수 있었다.

This study presents the standards for desirable local transfer of public affairs by analyzing the perceptions of experts in the academia and research institutes, as well as public officials in the environmental sector in charge of environmental affairs. The results of this study tend to be partially consistent with the results of previous studies that there is a difference in perception among respondents depending on the affiliation of experts and public officials. Among the policy tasks, there was a statistically significant difference among the respondents in perception of responsible agent for carrying out sustainable land planning and management. Regarding general environmental affairs, there was a statistically significant difference among pubic officials in different affiliations in perception of responsible executive agent for natural environment, living environment, and resource circulation.

The study on school indoor air quality was carried out at classrooms, computer-rooms, laboratories and play- grounds for carbonyl compounds including formaldehyde during the winter time from November to December 2004 and during the summer time from June to July 2005. The sampling was conducted under the general school condition without any artificial intervention such as the sealing, ventilating or heating at indoor environments. The concentrations of formaldehyde at all types of indoor environments were lower than air quality standard of $120{\mu}g/m^3$ for public facilities. The mean concentrations of formaldehyde at indoors were $4.5{\sim}6.1$ times higher than those at outdoors. From the comparison between two year and one year old schools after construction, the concentrations of formaldehyde in two year old school were $30{\sim}38%$ lower than those in one year old school measured at classrooms and laboratories.

This study analyzes the public lecture conducted by a university in Seoul and examined how a public lecture on the emergence of a new media environment could influence the actual field of engineering education. The current public lecture is changing away from past patterns which have been conducted on a daily, irregular and offline basis. Online lectures such as Mooc programs, as well as broadcast programs in the Internet media environment, are becoming increasingly popular with mainstream education. This study focuses on exploring how public lecture experiences of engineering professors have affected the improvement of learner centered education and their communication skills. It also examines how public lecture in the field can affect to enhance public understanding of engineering. The advent of a new media environment is likely to inject new vitality into a college lecture that seems to fall behind in the past. It is highly likely that the reliance on the teaching capabilities of professors become higher according to the emphasis on active learning environment. The genre of public lecture is expected to greatly helpful to expand future engineering education methodologies.
