토마토 유기재배 시설하우스 내에 자생하고 있는 큰망초와 엉겅퀴, 팥, 오이에 대하여 주 재배작물인 토마토와 황색끈끈이트랩에 유살된 담배가루이 성충의 유살량을 비교한 결과 담배가루이 밀도는 큰망초에서 가장 높았다. 오이의 경우 발생초기인 4월 3일과 4월 13일까지는 토마토보다 담배가루이 밀도가 높게 조사되었다. 8종의 콩에 대한 담배가루이 성충 유인수는 팥에서 보다 울타리강낭콩에서 더 많았으나 모든 식물체에 대해서는 낮은 유인효과를 보였다. 큰망초, 가지, 오이, 토마토에 대한 4-choice 아크릴 챔버를 이용한 후각계 반응에서 담배가루이는 시간이 지날수록 큰망초를 선호하였다. 큰망초에서 담배가루이 유충의 발육기간을 온도별로 조사한 결과, 온도가 높을수록 발육기간이 짧아져 $30^{\circ}C$의 경우 모든 발육단계에서 알은 약 0.5일, 유충은 약 1일 발육기간이 짧았다. The number of Bemisia tabaci adults attracted to horseweed, thistle, red bean, cucumber, and tomato plants, as measured by the number stuck to yellow sticky traps, was investigated in a polyvinyl greenhouse for growing tomatoes using organic methods. The number was highest on cucumber plants in the early days of B. tabaci infestation, but was highest on horseweed overall. Of the eight species of beans tested, B. tabaci adults were most attracted to Ultari-Gangnang; however, beans were not effective trap plants for B. tabaci. Measurement of olfactory behavioral response using a four-choice olfactometer showed that B. tabaci adults preferred horseweed to cucumber, eggplant, or tomato. The developmental period of B. tabaci eggs and larvae was shorter at high temperature. At $30^{\circ}C$, the developmental period of eggs and larvae on horseweed were reduced approximately 0.5 and 1 day, respectively, compared to those on cucumber or tomato.

The industrial use of MMMF(man-made mineral fibers), has been increasing, particularly since the banning of most asbestos products. Fibrous minerals can cause health abnormalities currently associated with occupational exposure to glass fiber. This study was conducted to evaluate health risks of glass fiber manufactory workers within the country. We examined questionaries, physical examination including auscultation, chest x-ray, pulmonary function test for 488 male workers, to go through their dermal itching symptoms and respiratory evaluation. we had the results as follows. 1. In 45% of the workers itching had been expressed at their entrance. At that time we was investigating, 18.5% had itching, and most of them complained it when they fall asleep and night. The Sequent itching site is waist and groin, upper and lower extremity in order, and it had been expressed mainly during summer and winter. 2. As the results of ventilatory functions test, 6.0% were obstructive type, 1.0% were restrictive type. So, glass fiber exposures should be controlled or elimination by protective devices in the workplace. 3. The means of FVC, $FEV_1,\;FEV_1%$ were in normal range. As the comparison of ventilatory functions by age groups, MMF was decreased significantly for the group, 50 years old and more than other groups. And the comparison by the serving periods at glass fiber producing factory, MMF was decreased for the workers had worked for $11\sim15$ years. Therefore, MMF be more sensitive index in the evaluation of ventilatory impairments caused by glass fiber workers.

This paper proposes a specific modification method that is made to useful query transformation of original user input query into the information retrieval engine using Korean natural language. The question-answering training set which, obtain a proper set of question-answering sentences on world wide web, employs to find a type of question query phrases and to make a candidates for the transformation. The type of question query phrases used to analysis of question query, selection of the candidate for transformation and extraction of the focus phrase. The candidates for the transformation consist of pre-defined words or phrases used to increase the efficiency of extraction and used for transformation of original input query. Therefore, transformation method is changed from original query into substituted query for candidate words [or phrases]. In this paper, The result shows that experimental tests are more higher precision than the information retrieval engine using the original user input queries.

Flour dust is well known as causing occupational asthma. A case of occupational asthma caused by flour dust broke out in a big-sized bakery in Korea in 2005. The study was carried out to evaluate the exposure level of flour dust and to find out the health status in bakers in the bakery. The sampled product lines were 7 and each line basically has weighing, pouring, mixing, cutting, forming, packing, oven, wrapping. The total and inhalable-sized dust samples were simultaneously obtained in workers directively exposed to flour dust. The exposure levels of total and inhalable dust were ranged in 0.272~1.271 ㎎/㎥ (GM) and 0.650~7.206 ㎎/㎥(GM) respectively in the 7 sampled lines. The ratio of inhalable and total flour dust is approximately 3.39 resulted from linear regression analysis. The positive rates in skin prick test were 16.61% and 7.69% respectively, and the positive rates in serum specific IgE test were 16.45% and 16.88% respectively in male and female group directively exposed to flour dust. The total sensitized rate in both tests was 25%. According to PFT, methacholine bronchial hyperresponsiveness and specific challenge test, maximum prevalence of occupational asthma caused by flour dust was approximately 2%. The results indicated that the exposure levels of flour dust have exceeded 0.5 ㎎/㎥ as inhalable dust and could have sensitized workers exposed to flour dust. The improvement of working environment and the execution of periodic medical examination were needed to reduce the exposure level of flour dust and to find abnormal health conditions in the bakery.

We evaluated the relations among exposure and urinary levels of Cr, folate, vitamin B12 and Hcy levels in the workers chronically exposure to Cr. Subjects were 104 male employees, 65 workers exposed to Cr in 9 electroplating plants and 39 office workers who had never been occupationally exposed to hazardous substances including Cr. The geometric mean(GM) of Cr in workplace was 0.069±0.101 ㎎/m3 and urinary Cr was 0.483±0.394 ㎎/g creatinine and airborne Cr concentration was significantly correlated to the urinary concentration of Cr(r=0.900, p=0.000). The geometric mean concentration of urinary Cr in control group was 0.301±0.255 ㎎/g creatinine. In comparing the workers exposed to Cr with controls, significantly higher mean plasma levels were found of Hcy(11.3±4.9 vs 9.4±4.7 μmol/ℓ, p=0.05), but vitamin B12 levels (181.8±68.7 vs 216.0±64.3 nmol/ℓ, p=0.01) was significantly decreased. Hcy concentrations correlated positively with airborne Cr concentrations(r=0.287, p=0.004) and urinary Cr concentrations(r=0.244, p=0.015) but folate concentrations correlated negatively with airborne(r=-0.234, p=0.020) and urinary Cr concentrations(r=-0.640, p=0.090), respectively. No correlations were observed between vitamin B12, airborne and urinary Cr concentrations. Also, Hcy concentrations correlated positively with vitamin B12(r=0.295, p=0.0020 and negatively with folate concentrations(r=-0.196, p=0.046). The various biological(i.e. age and serum indicates) or lifestyle factors(i.e. medication, smoking, alcohol and coffee intake), also taken into account as potential confounders, did not influence the correlations found. Thus, this study found evidence that Cr might be associated with elevated plasma levels of Hcy. Furthermore, elevated plasma levels of Hcy were significantly associated with folate and vitamin B12 concentration.

통계 기반 접근 방법을 이용한 품사태깅에서 태깅 정확도는 훈련 데이터의 양에 좌우될 뿐 아니라, 말뭉치가 충분할지라도 수작업으로 구축한 말뭉치의 경우 항상 오류의 가능성을 내포하고 있으며 언어의 특성상 통계적으로 신뢰할만한 데이터의 수집에도 어려움이 따른다. 훈련 데이터로 사용되는 말뭉치는 많은 사람들이 수작업으로 구축하므로 작업자 중 일부가 언어에 대한 지식이 부족하다거나 주관적인 판단에 의한 태깅 실수를 포함할 수도 있기 때문에 단순한 저빈도와 관련된 잡음 외의 오류들이 포함될 수 있는데 이러한 오류들은 재추정이나 평탄화 기법으로 해결될 수 있는 문제가 아니다. 본 논문에서는 HMM(Hidden Markov Model)을 이용한 한국어 품사 태깅에서 재추정 후 여전히 존재하는 말뭉치의 잡음에 인한 태깅 오류 해결을 위해 비터비 알고리즘 적용 단계에서 데이터 부족과 말뭉치의 오류로 인해 문제가 되는 부분을 찾아내고 규칙을 통해 수정을 하여 태깅 결과를 개선하는 방안을 제안한다. 실험결과는 오류가 존재하는 말뭉치를 사용해 구현된 HMM과 비터비 알고리즘을 적용한 태깅 정확도에 비해 오류를 수정하는 과정을 거친 후 정확도가 향상됨을 보여준다.

Mean densities of two-spotted spider mite (TSM), Tetranichus urticae Koch adults from January to April in 2014 to investigate the occurrence and dispersion pattern of T. urticae on purpose of developing a monitoring method in the strawberry PVC house. Difference of density of T. urticae adult on middle and both side of leaf wasn’t significantly. Density of T. urticae in investigation at different furrows and investigating points was the highest at the right and left sides of a furrow in strawberry PVC house. In results of comparing the dispersion incides of Taylor’s power law (TPL) with Iwao’s patchiness regression (IPR), TPL described better mean-relationship for the dispersion indieces compared to IPR. Slopes and intercepts of TPL from leaf samples did not differ among surveyed regions. Also, Distribution of T. urticae in a strawberry PVC house was the gravitation of the distribution because b and β values of TPL and IPR was bigger than 1.
