  • This paper presents an overview of the UK Hydrocarbon Monitoring Network and summarises some of the lessons learnt from running and automated VOC monitoring network in th UK. The paper will describe the operation of the network and the Quality Control and Quality Assurance (QA/QC) procedures used to ensure that the data qality objectives are met. The provision of accurate measurements of ambient air pollutant concentrations is a valuable and high-profile service of Governments, assisting policy decisions and allowing members of the public to be well-informed. The need for such measurements has been increased in the UK by the National Air Quality Strategy and European Air Quality Directives, with the National Networks playing a central role in delivering the information. The Hydrocarbon Network provides measurements directly in support of monitoring requirements for benzene and 1,3-butadiene, and of 23 other hydrocarbon species important for their role in ozone and secondary particulate formation.

  • Investigation of the quality characteristics of Takju brewing mashes prepared with several different yeasts was carried out during the 42-day brewing process, including examination of titratable acidity, amino acid content, sugar contents, alcohol contents, pH, reducing sugar, yeast population, lactic acid bacteria, and sensory evaluation. Fermivin yielded the highest titratable acidity, while la parisienne had the lowest. Fermivin also had the highest value of amino acid content (14.33%), while other yeasts shows period tended to increase over exclude Instaferm and Song chun. The amount of sugars in instaferm ($11.33^{\circ}Bx$) and instaferm red ($10.53^{\circ}Bx$) were higher than those in La parisienne red and Song chun ($9.57^{\circ}Bx$). The alcohol contents of instaferm was the highest value (15.20%) while the alchol content of the other yeasts tended to increase the fementation period. Fermivin had the highest pH at $12^{th}$ day among the yeasts(4.02), Instaferm red had the lowest pH among the yeasts (3.87) while safbrew wb-06 had the highest reducing sugar content(117.60 mg/mL). Instaferm obtained the highest preference in the sensory evaluation for all items.

  • This study investigated four universities in Busan and compared each other about the dimensions of service qality and relevant concepts. For empirical study, 288 respondents re sampled and six hypotheses are analyzed by using regression analysis and ANOVA. A survey was conducted with four university's students to see if there were significant differences in their perception(expectation, performance, perceived service quality, customer satisfaction, intention of repurchase) of a university administration service quality. The principal findings of this study are as follows: (1) A comparison of universities in terms of their expectations about university administration service revealed no differences, but performance revealed differences in specialization and reliability. (2) All of service dimensions, tangibles, reliability and specialization had significant impact on overall service quality. Specialization had the most significant impact on overall service Quality in A and D university, but tangibles had the most significant impact in B university. (3) Overall service Quality has a significant positive effect on customer satisfaction, but the degree of effect is different from each other. (4) Customer satisfaction has a significant positive effect on intention of repurchase, but the degree of effect is different from each other. In conclusion this study, however has a limitation about questionnaire, offers some strategic directions for developing the specific marketing strategies of university.

  • Purpose: This study was to investigate the factors influencing on the quality of life (QOL) among herniation of nucleus pulposus (HNP) patients caused by occupational accidents. Method: 203 patients of HNP were recruited. 106 patients were occupationally injured workers who benefited from workmen's compensation scheme (PWCS group), and 43 patients were non-occupationally injured workers benefiting from national health insurance (PNHI group). Questions of QOL items were used by Korean version of SBQOL (SmithKlein Beecham's Qality of Life). Result: The quality of life of PWCS group measured by SBQOL was significantly lower than that of PNHI group. In PWCS group, SBQOL was significantly lower in patients with 40s of their age, 5 years or longer of treatment duration, no expectation of return to work, no expectation of recovering subject's health, and with loss of employment than rest of the patients in each category. Expectations of recovering subject's health showed to be affect factors on QOL both the PWCS and PNHI groups. Conclusion: It suggested that betterment of expectation of recovering patient's health and an administrative system for returning to work of the occupationally injured HNP patients during treatment be necessary for improvement of their quality of life.

  • This experiment was carried out to determine the effect of harvesting dates on the dry matter yield and quality of "Kool grazer" winter rye(Seca1e cereale L.) as a soilage crop at the Forage Experimental Field of College of Agrlc. and Life Sciences, SNU, Suweon. Four-day harvasting interval was allocated to measure the growth, yield and quality of rye from April 14 to May 18, 1987. Rye was rapidly grown as 3 cm/day and the growth was linearly recorded from the elongation to flowering stage. The dry matter and in vitro digestible dry matter(1VDDM) yields per ha were linearly increased up to 0.26 and 0.19 tonlday from April 14 to May 4 and April 14 to 29, respectively, but major breaks in yield increases occurred at the 50% heading stage, than yields increased. The highest crude protein yield was observed at the first heading stage of April 29, then decreased. Acid detergent fiber (ADF) and crude protein(CP) contents of rye at the heading stage of May 5 were 35 and 17%, respectively and the nutritive value of rye in terms of ADF and CP contents was evaluated as the I st grade hay, but neutral detergent fiber(NDF) content of rye was 47 % at the boot stage ofApril 22 and evaluated as the 2nd grade hay in terms of NDF content. The results indicate that the first heading stage or the end of April would be the most suitable harvesting time for early maturing winter rye as a soilage crop in terms of yield and quality in the middle northwestern coast rcgion of Korea. of Korea.

  • 본 연구에서는 서울시에 의해 운영되는 서울시내 31개 지역의 대기오염 자동측정망에서 1990년부터 2000년까지 11년 동안 측정한 자료 중, TSP와 PM$_{10}$에 대한 대기환경기준을 초과한 자료만을 선택적으로 분리한 후 여러 가지 통계적인 분석을 수행하였다. 이러한 연구목적에 맞추어, 각 토지 이용 상태별로 환경기준을 초과한 분진농도의 경향성을 비교해 본 결과, TSP의 경우 초과농도의 전반적인 발생분포가 녹지, 주거, 상업, 준공업지역 순서로 증가하는 양상을 보여주었다. 준공업 지역에서 351.0${\pm}$35.9${\mu}$g m$^3$로 가장 높은 초과농도를 보였다. PM$_{10}$의 초과농도는 주거지역에서 182.9${\pm}$42.4${\mu}$g m$^3$의 최고농도를 보이며, 초과농도분포는 준공업, 상업, 녹지, 주거지역 순서로 증가하는 양상을 보인다. 발생빈도수를 각 지점별 측정망수로 나누어 준 결과 주거지역에서 21회로 다른지역에 비해 높은 초과빈도수를 보였다. 이들 초과농도자료들만에 국한시켜 시간적 주기성을 분석한 결과에 따르면, 일반적으로 관측되는 부유분진 자료들과 차별화 된 경향성이 어느 정도 확인되었다. 특히 계절적인 주기로 구분하였을 때, 일반농도자료는 PM$_{10}$과 TSP 모두 겨울철에 가장 큰 농도를 보인데 반해, 초과농도는 다른 양상을 보여주었다. 이러한 연구결과, PM$_{10}$의 연도별 경향성에서 가장 주목할 점은 측정이 시작된 1995년 이후 초과농도의 크기가 지속적으로 감소함에도 불구하고, 그 발생빈도수는 최근에 들어 괄목할 만큼 증가하고 있다는 점을 들 수 있다.
