  • The objective of the present study was to perform a comparative analysis of the chemical properties of the cultivation site soil and growth characteristics of organically and conventionally cultivated ginseng (Panax ginseng C. A. Meyer). Organically and conventionally cultivated ginseng samples (4-, 5-, and 6-year-old) were collected from 52 fields at 14 locations throughout Korea. The samples were collected over three years from 2013 to 2015, with the collection period between October and November of each year. In order to increase the yield of organically cultivated ginseng, the amount of nutrients was increased to match that of the conventional cultivation system, which highlights the need for proper management in accordance with the standards for chemical properties of soil. Growth duration of organic ginseng was ${\geq}60days$ shorter than that of conventional ginseng and its average yield per 1ha was 60% than that of conventional ginseng. Root weight of organically cultivated ginseng was approximately 54% that of conventionally cultivated ginseng. Rhizome diameter and body shape index of organically cultivated ginseng were lower than those of conventionally cultivated ginseng, indicating that organically cultivated ginseng was thinner and longer than conventionally cultivated ginseng. Root length was greater in 5-year-old conventionally cultivated ginseng with a low percentage of paddy-upland rotation fields. The number of rootlets was lower in 5- and 6-year-old organically cultivated ginseng with a high percentage of direct seeding cultivation. Dry weight was distinctly lower in 5- and 6-year-old organically cultivated ginseng with early defoliation than that of conventionally cultivated ginseng. Incidences of notched belly and root rot tended to be higher in conventional cultivation, with the incidence of notched belly being distinctly higher in 4- and 6-year-old roots and root rot being more prevalent in 5- and 6-year-old roots. Red discoloration and eelworm damage, which are highly affected by soil moisture, were most common in the organically cultivated 4-year-old roots. Organically cultivated ginseng showed early defoliation than conventionally cultivated ginseng, as a result, its yield and weight were low, while the incidence of physiological disorders was low. In order to increase the yield of organically cultivated ginseng, studies on cultivation technology that can overcome early defoliation, as well as soil moisture management that can minimize physiological disorders, are required.

  • Recently, it is continuously rising to concern about the health risk being induced by microorganisms in food such as Escherichia coli O157:H7 and Listeria monocytogenes. Various organizations and regulatory agencies including U.S.FPA, U.S.DA and FAO/WHO are preparing the methodology building to apply microbial quantitative risk assessment to risk-based food safety program. Microbial risks are primarily the result of single exposure and its health impacts are immediate and serious. Therefore, the methodology of risk assessment differs from that of chemical risk assessment. Microbial quantitative risk assessment consists of tow steps; hazard identification, exposure assessment, dose-response assessment and risk characterization. Hazard identification is accomplished by observing and defining the types of adverse health effects in humans associated with exposure to foodborne agents. Epidemiological evidence which links the various disease with the particular exposure route is an important component of this identification. Exposure assessment includes the quantification of microbial exposure regarding the dynamics of microbial growth in food processing, transport, packaging and specific time-temperature conditions at various points from animal production to consumption. Dose-response assessment is the process characterizing dose-response correlation between microbial exposure and disease incidence. Unlike chemical carcinogens, the dose-response assessment for microbial pathogens has not focused on animal models for extrapolation to humans. Risk characterization links the exposure assessment and dose-response assessment and involve uncertainty analysis. The methodology of microbial dose-response assessment is classified as nonthreshold and thresh-old approach. The nonthreshold model have assumption that one organism is capable of producing an infection if it arrives at an appropriate site and organism have independence. Recently, the Exponential, Beta-poission, Gompertz, and Gamma-weibull models are using as nonthreshold model. The Log-normal and Log-logistic models are using as threshold model. The threshold has the assumption that a toxicant is produce by interaction of organisms. In this study, it was reviewed detailed process including risk value using model parameter and microbial exposure dose. Also this study suggested model application methodology in field of exposure assessment using assumed food microbial data(NaCl, water activity, temperature, pH, etc.) and the commercially used Food MicroModel. We recognized that human volunteer data to the healthy man are preferred rather than epidemiological data fur obtaining exact dose-response data. But, the foreign agencies are studying the characterization of correlation between human and animal. For the comparison of differences to the population sensitivity: it must be executed domestic study such as the establishment of dose-response data to the Korean volunteer by each microbial and microbial exposure assessment in food.

  • This study is to investigate microbiological hazards which can be used as fundamental data to adequately control leeks hazards and develop leeks GAP model for those who want to get GAP system. The microbiological investigations on cultivation environments (soil and water), crops (leeks), personal hygiene (workers' hands, clothes and gloves) and working tools (boxes) have been conducted for one year, so the period was classified under non-cultivation, cultivation, and post harvest. Total bacteria was detected from soil (4.0~6.7 log CFU/g), leeks (4.6~5.1 log CFU/g), hands (ND~3.3 log CFU/hand) and gloves ($ND{\sim}5.4\;log\;CFU/cm^2$) while nothing was detected from the other samples. The coliform contamination of leeks (4.8~5.0 log CFU/g) was more high than that of soil (3.9~4.2 log CFU/g). In case of foodborne pathogens, only B. cereus was detected at the level of 0.5~4.6 log CFU/g (or hand, $100cm^2$). Fungi was observed at the level of 2.1~3.8 log CFU/g (or hand, $100cm^2$) excepting water and some working tools. These results demonstrate that the contamination of leeks is comparatively higher than that of soil sample. The reason may be the cross-contamination by biological hazards presenting on soil. Therefore, it is necessary to properly control soil and fertilizer for safety against biological hazards.

  • The Korean fresh pork loins in vacuum packaged were obtained from three different Korean export companies and investigated for microbiological and sensory properties. The fresh pork loins were stored at 2$^{\circ}C$ for 50 days and analyzed with an interval of 5$\sim$10 days. The results were as follows: The overall numbers of total plate counts and coliform bacteria were higher in swab method than in meat sampling method. The total plate counts in the loins from the company I were maintained low levels ($\prec$10$^5$ cfu/$cm^2$ or $\prec$10$^5$ cfu/g) for entire storage periods(50 days at 2$^{\circ}C$), whereas the loins from the company III had high levels when they were compared to the domestic standard for the allowance limit. The samples from the company III showed that total plate counts were over 106 after about 30 days when determined by meat sampling method and total plate counts were over 106 after 15 days when determined by swab method. The overall numbers of coliform bacteria were also significantly lowest in the samples from the company I, whereas they were highest in the company III. Therefore, all meat companies will have to make an effort to prevent bacterial contamination in each stage such as slaughtering, marketing and consumer in order to ensure the production of safe meat and the extension of shelf-life. For fresh products, scores of intramuscular fat were higher in samples form the companies II and III than those from the company I when visibly evaluated with the standard. There were no significant differences in scores of meat color, drip and fresh meat flavor. However, the samples from the company I had the lowest score of off-flavor and highest score of overall acceptability. For cooked products, there were no significant differences in meat flavor, off-flavor, juiciness and overall acceptability.

  • Arbutin, which is used as a whitening ingredient, can produce hydroquinone, known as causing skin disease and carcinogen. Preservatives are essential to prevent microbial contamination during long-term storage and use of cosmetics, but safety issues such as toxicity and skin irritation are being raised. This study was conducted to determine hydroquinone and 21 preservatives levels in 40 arbutin-containing whitening functional cosmetics sold on-line and off-line. Result showed that 9 products contained hydroquinone. The concentrations in 7 products were ranged from 0.3 to 0.9 ppm, which were within the maximum allowed amount established by the Ministry of Food and Drug Safety. However, 2 products were 8.4 and 50.5 ppm and exceeded the allowed amount. Preservatives were detected 20 products. Detected items and ranges were phenoxy ethanol 0.1 ~ 0.7% (N = 15), Methyl paraben 0.19 ~ 0.21% (N = 2), Chlorphenesin 0.13% (N = 1), chlorhexidine 0.006% (N = 1), Propyl paraben 0.06% (N = 1), which were within maximum allowed amount established by the Ministry of Food and Drug Safety. Also, in cases of functional cosmetics the phrase "functional cosmetics" should be expressed on the primary or secondary package of cosmetics by cosmetics act. However, 1 product did not state the phrase as functional cosmetics. This study suggest that preservatives were safely managed. However, hydroquinone in hydroquinone-detected products could be produced by the decomposition of arbutin. Thus, further studies on the decomposition of arbutin are required to improve the quality control of the cosmetics.

  • The experiments were conducted to study the influence of growth location and cutting microelements macro-and on managements in temperate grasses in Korea and West Germany from 1975 to 1979. The field trials were designed as split plot with three grass species of Dactylis glomerata L., Lolium perenne L. and Festuca pratensis Huds under three cutting regimes at grazing stage, silage stage and hay stage. The results obtained are summarized as follows: 1. Concentrations of macro-and microelements in temperate grasses showed a different response to growth location and growing season. P concentration in the plants was decreased under hot stress in summer, whereas Mg and Na tended to be increased. The seasonal changes in K and Zn were not significant. 2. Morphological growth stage was to be found as an important factors influenced to mineral components. P and K contents in temperate grasses tended to be decreased as morphological development especially under high temperature in Suweon and Cheju. Ca and Mg were less affected by morphological stage and cutting managements. 3. Mean value of Ca/P ratio in the plants were 1.58, 1.33 and 1.21 for meadow fescue, perennial ryegrass and orchardgrass, respectively. Ca/P ratio in grasses tended to be increased as morphological development. 4. Zn deficiency in the plants occured in all grass species and experimental sites. Mean Zn concentration of the plant were 34.2%, 31.2% and 37.8% for Suweon, Cheju and Taekwalyong, respectivelly. Na deficiency occured in orchardgrass and meadow fescue, especially in taekwalyong. Cool temperature resulted in a decrease of Na absorption and accumulation.

  • This study was carried out to examine foodborne pathogenic contamination from 1,080 samples of cooked hams and sausages at 10 Korean processing facilities in 2010. The samples were collected from the six primary and additional sterilization products in same lot. To detect Salmonella spp., Staphylococcus aureus, Listeria monocytogenes and Clostridium perfringens in those products (n=1,080), the domestic standard method for Processing and Ingredients Specification of Livestock Products was used. As a result, Salmonella spp. was not detected in all 636 ham and 444 sausage samples. However, L. monocytogenes was detected in four (0.6%) ham and eight (1.8%) sausage samples from five manufactures. S. aureus was also only detected in 4 (0.6%) ham samples from two manufacturers, and C. perfringens was detected in 3 (0.5%) ham samples from three manufacturers, the contamination levels of these pathogens were less than 100 CFU/g. In conclusion, the results of this study indicate that the additional sterilization step of processing manufacturers could not assist to control the foodborne pathogenic bacteria.

  • This study was conducted to investigate the content of sulfur dioxide, carotenoids and the degree of contamination of Bacillus cereus in 33 kinds of dried sweet potato from domestic mainly dried agricultural products in Korea. According to the characteristics of dried sweet potato samples, it was classified into four clusters and as a result of analyzing the contents of sulfur dioxide, carotenoids and the degree of contamination B. cereus was no significant difference among the clusters. The detection ranges of residual sulfur dioxide from 33 dried sweet potatoes ranged from 0.38 to 28.16 mg/kg, three cases (9.09%) were detected at the reference level of 10 mg/kg or more. But no samples exceeding 30 mg/kg, the tolerance level of sulfur dioxide in dried sweet potatoes were detected. Since dried sweet potato does not have a standard for carotenoids, when comparing the national and international standards of carotenoids, the range of detection of carotenoids in dried sweet potato was $46{\sim}2,663{\mu}g$/100 g, which was within the reference range of $0{\sim}9,826{\mu}g$/100 g. In principle colonies suspected to be B. cereus in dried sweet potato were not detected. In 7 cases (21.21%), there were detected in the range of 0.05~1.59 log CFU/g but not more than 3 log CFU/g as the reference value. The results of this study are expected to be used as basic data to establish quality standard for dried sweet potatoes. In order to control the quality of dried sweet potatoes in domestic market, raw materials, drying method and packaging after distribution, it is necessary to maintain and maintain the process steadily.

  • The objective of this study was to measure backscattering coefficients of paddy rice using a L-, C-, and X-band scatterometer system with full polarization and various angles during the rice growth period and to relate backscattering coefficients to rice growth parameters. Radar backscattering measurements of paddy rice field using multifrequency (L, C, and X) and full polarization were conducted at an experimental field located in National Academy of Agricultural Science (NAAS), Suwon, Korea. The scatterometer system consists of dual-polarimetric square horn antennas, HP8720D vector network analyzer ($20\;MHz{\sim}20\;GHz$), RF cables, and a personal computer that controls frequency, polarization and data storage. The backscattering coefficients were calculated by applying radar equation for the measured at incidence angles between $20^{\circ}$ and $60^{\circ}$ with $5^{\circ}$ interval for four polarization (HH, VV, HV, VH), respectively. We measured the temporal variations of backscattering coefficients of the rice crop at L-, C-, X-band during a rice growth period. In three bands, VV-polarized backscattering coefficients were higher than hh-polarized backscattering coefficients during rooting stage (mid-June) and HH-polarized backscattering coefficients were higher than VV-, HV/VH-polarized backscattering coefficients after panicle initiation stage (mid-July). Cross polarized backscattering coefficients in X-band increased towards the heading stage (mid-Aug) and thereafter saturated, again increased near the harvesting season. Backscattering coefficients of range at X-band were lower than that of L-, C-band. HH-, VV-polarized ${\sigma}^{\circ}$ steadily increased toward panicle initiation stage and thereafter decreased, and again increased near the harvesting season. We plotted the relationship between backscattering coefficients with L-, C-, X-band and rice growth parameters. Biomass was correlated with L-band hh-polarization at a large incident angle. LAI (Leaf Area Index) was highly correlated with C-band HH- and cross-polarizations. Grain weight was correlated with backscattering coefficients of X-band VV-polarization at a large incidence angle. X-band was sensitive to grain maturity during the post heading stage.

  • 생활수준이 낮은 단계에 있어서는 우선 식량에 대한 수요가 강하다. 인간의 욕구가 만족스럽게 먹는다는 것에 대하여 제일 강하게 발동하는 것이다 그러나 점차 과학기술과 산업과 경제가 발전하여 성장과정에 오르게 되고 소득수준도 향상하게 되면 시장기구를 통해서 구입 할 수 있는 개인의 물적 소비재에 대해서는 점차 충족하게 되며 식량이외에도 의복, 전기기구 및 일용생활용품, 자동차 등에 이르기까지 더욱 고차원의 소비재가 보급하게 되는 것이다. 이렇게 되며는 사람의 욕구는 사적 재물이나 물적 수요에서 점진적으로 공공재나 또는 질적 수요(주택, 생활환경 등)의 방향으로 움직이게 되는 것으로써 여기에 환경오염 또는 공해문제에 대하여 의식하게 된다. 그러나 여기에서 더욱이 문제점이 되는 것은 소득 수준의 향상 과정이란 그 자체가 환경오염의 커다란 요인이라는 점이며 자동차의 급격한 보급과 생활의 편의성을 구하여 집중되는 도시인구의 집적, 높은 소득을 보장하기 위한 생산성 높은 중화학공업의 발전 등등은 그 자체가 환경권이란 사람이 요구하는 고차원의 권리를 침해하는 직접적인 요인이 된다는 것이다. 이와 같은 환경오염이나 공해문제에 대한 세계적인 논의는 이미 시작된 지 오래이지만 현재는 우리의 건강보호를 위해서나 생활환경의 보전을 위해서라는 점에서는 그치는 것이 아니고, 더욱 넓혀서 자연의 보호, 자원의 보호라는 견지로 확대되고 있다. 이와 같은 세계적인 확대된 이해와 이에 대한 대책강구의 제안은 1968년 국제연합의 경제사회이사회에서 스웨덴 정부대표에 의하여 제시되었으며 1969년의 우- 탄트 사무총장의 인간환경에 관한 보고서, 1970년 Nixon 미대통령의 연두일반교서 그리고 1972년 5월 6일 스웨덴의 스톡홀롬에서 개최되는 인간환경회의의 주제 등을 통해서 알 수 있고, 종래의 공해나 생활환경의 오염문제라는 좁은 개념에서가 아니고 인간환경전체의 문제로 다루고 있는 것이다. 즉 환경개발(도시, 산업, 지역개발에 수반된 문제), 환경오염(인위적 행위에 의하여 환경의 대인간조건이 악화하는 문제) 자연ㆍ자원의 보호관리(지하, 해양자원, 동식물, 풍경경치의 문제)란 3개 측면에서 다루고 있는 것이다. 환경오염이란 문제를 중 심하여 보면 환경을 구성하는 기본적인 요소로서 대기, 물, 토지 또는 지각. 그리고 공간의 사대요소로 집약하여 생각할 수 있음으로 이 4요소의 오염이 문제가 되는 것이다. 대기의 오염은 환경의 오염중 가장 널리 알려진, 또 가장 오랜 역사를 가진 오염의 문제로써 이에 속하는 오염인자는 분진, 매연, 유해가스(유황산화물, 불화수소, 염화수소, 질소산화물, 일산 화염소 등) 등 대기의 1차 오염과 1차 존재한 물질이 자외선의 작용으로 변화발생 하는 오존, PAN등 광화학물질이 형성되는 2차적인 오염을 들 수 있다. 기외 카도미움, 연등 유해중금속이나 방사선물질이 대기로부터 토지를 오염시켜서 토지에 서식하는 생물의 오염을 야기케 한다는 점등이 명백하여지고 있으며 대기의 오염은 이런 오염물질이 대기중에서 이동하여 강우에 의한 침강물질의 변화를 일으키게 되며 소위 광역오염문제를 발생케하며 동시에 토지의 토질저하등을 가져오게 한다. 물의 오염은 크게 내육수의 오염과 해양의 오염의 양면으로 나누어 볼 수 있다. 하천의 오염을 방지하고 하천을 보호하기 위한 움직임 역시 환경오염의 역사상 오래된 문제이며 시초에는 인분뇨와의 연결에서 오는 세균에 의한 오염이나 양수 기타 일반하수와의 연결에서 오는 오염에 대비하는 것부터 시작하였지만 근래에는 산업공장폐수에 의한 각종 화학적유해물질과 염료 그리고 석유화학의 발달에 의한 폐유등으로 인한 수질오탁문제가 점차 크게 대두되고 있다. 이것은 측 오염이란 시초에 우리에게 주는 불쾌감이 크므로 이것을 피하자는 것부터 시작하여 인간의 건강을 지키고 각종 사용수를 보존하자는 용수보존으로 그리고 이제는 건강과 용수보존뿐만 아니라 이것이 농림 수산물에 대한 큰 피해를 주게됨으로써 오는 자연환경의 생태계보전의 문제로 확대전환하고 있는 것이다. ?간 특히 해양오염에 대한 문제는 국지적인 것에만 끝이는 것이 아니고 전세계의 해양에 곧 연결되는 것이므로 세계각국의 공통관심사로 등장케 되었으며 이것은 특히 폐유가 유류수송 도중에 해양에 투기되는 유류에 의한 해양의 유막성형에서 오는 기상의 변화와 물피해등이 막심함으로 심각화 되고 있다. 각국이 자국의 해안과 해양을 보호하기 위하여 조치를 서두르고 있는 현시점에서 볼 때에는 이는 국제문제화하고 있으며 세계적인 국제적 협력과 협조의 필요성이 강조되는 좋은 예라 하겠다. 토양의 오염에 있어서는 대기나 수질의 오염이 구국적으로 토양과 관련되고 토양으로 환원되는 것이지만 근래에 많이 보급사용되는 농약과 화학비료의 문제는 토양자체의 오염에만 그치는 것이 아니고 농작물을 식품으로 하여 섭취함으로써 발생되는 인체나 기타생물체의 피해를 고려할 때 더욱 중요한 것이며, 또 토질의 저하를 가져오게 하여 농림생산에 미치는 영향이 적지 않을 것이다. 지반강하는 지각 에 주는 인공적 영향의 대표적인 것으로써 지하수나 지하 천연가스를 채취이용하기 위하여 파들어 감으로써 지반이 침하 하는 것이며 건축물에 대한 영향 특히 풍수해시의 재해를 크게 할 우려가 있는 것이다. 공간에 있어서의 환경오염에는 소음, 진동, 광선, 악취 등이 있다. 이들은 특수한 작업환경의 경우를 제외하고는 건강에 직접적인 큰 피해를 준다고 생각할 수 없으나 소음, 진동, 관선, 악취 등은 일반 일상시민생활에 불쾌나 불안을 줌으로써 안정된 생활을 방해하는 요인이 되는 것이다. 공간의 오염물로써 새로운 주목을 끌게된 것은 도시산업폐기물로써 이들은 대기나 물 또는 토지를 오염시킬 뿐만 아니라 공간을 점령함으로써 도시의 미관이나 기능을 손상케 하는 것이다. 즉 노배폐차의 잔해, 냉장고등고형폐기물등의 재생불가능한 것이나 비니루등 합성물질로 된 용기나 포장 등으로 연소분해 되지 않은 내구소비재가 이에 해당하는 것으로 이는 maker의 양식에 호소하여 그 책임 하에 해결되어야 할 문제로 본다. 이렇듯 환경오염은 각양각색으로 그 오염물질의 주요 발생원인 산업장이나 기타 기관에서의 발생요인을 살펴보며는 다음과 같은 것으로 요약할 수 있다. A. 제도적 요인 1. 관리체재의 미비 2. 관리법규의 미비 3. 책임소재의 불명확 B. 자재적 요인 1. 사용자재의 선택부적 2. 개량대책급 연구의 미흡 C. 기술적 요인 1. 시설의 설계불량, 공정의 결함 2. 시설의 점검, 보전의 불충분 3. 도출물의 취급에 대한 검사부족 4. 발생방지 시설의 미설치, 결함 D. 교육적 요인 1. 오염물질 방제지식의 결여 2. 법규의 오해, 미숙지 E. 경제적 요인 1. 자금부족 2. 융자상의 문제 3. 경제성의 문제 F. 정신적 요인 1. 사회적 도의심의 결여(이기주의) 2. 태만 3. 무지, 무관심 등이다. 따라서 환경오염의 방지란 상기한 문제의 해결에 기대하지 않을 수 없으나 이를 해결하기 위하여는 국내적 국제적 상호협조에 의한 사회각층의 총력적 대책이 시급한 것이다. 이와 같은 환경오염이 단속된다 하며는 미구에 인류의 건강은 물론 그 존립마저 기대하기 어려울 것이며, 현재는 점진적으로 급성피해에 대하여는 그 흥미가 집중되어 그 대비책도 많이 논의되고 있지만 미량의 단속접촉에 의한 만성축적에 관한 문제나 이와 같은 환경오염이 앞으로 태어날 신생률에 대한 영향이나 유전정보에 관한 연구는 장차에 대비하는 문제로써 중요한 것이라 생각된다. 기외에 우려되는 점은 오염방지책을 적극 추진함으로써 올 수 있는 파생적인 문제이다. 즉 오염을 방지하기 위하여 생산기업체가 투자를 하게 되며는 그만큼 생산원가가 상승할 것이며 소비가격도 오를 것이다. 반면 이런 시책에 뒤떨어진 후진국의 값싼 생산국은 자연 수입이 억제 당할 것이며, 이렇게되면 후진국은 무역경쟁에서 큰 상처를 입게될 것이고 뿐만 아니라 선진국에 필요한 오염물질의 발생이 높은 생산기기를 자연후진국에 양도하게 될 것임으로 후진국의 환경오염은 배가할 우려가 있는 것이다. 또 해양오염을 방지할 목적에서와 같이 자국의 해안보호를 위하여 마련된 법의 규제는 타국의 선박운항에 많은 제약을 가하게 될 것이며 이것 역시 시설이 미약한 약소후진국의 선박에 크게 영향을 미치게 될 것임으로 교통, 해운, 무역등을 통한 약소후진국의 경제성장에 제동을 거는 것이 될 것이다. 이렇듯 환경오염의 문제는 환경자체에 대해서만 아니라 부산물적으로 특히 후진국에는 의외 문제를 던져주게 되는 것임으로 환경오염에 대해서는 물론, 전술한 바와 같이 인간환경전체의 문제로써 Nixon 대통령이 말한 결의와 창의와 그리고 자금을 가지고 과감하게 대처해 나가야 할 것이다.
