This paper discusses the nature of the associate NP of English there constructions and attempts to capture the underlying similarity between the associate NP in English and the nominative object in Korean. Specifically, this paper is centered on the Case property of the associate NP. As the first step, previous proposals on the case of the associate NP are critically reviewed. Through the criticism, this paper opposes to Chomsky's (1995, 2000, 2001) analysis and to Lasnik's (1999) partitive Case analysis. In particular, convincing reason for the partitive Case assignment to the associate NP, other than other cases, cannot be found. This paper, therefore, adopts a recent claim of Boeckx (2000) that the Case under consideration is nominative by Agree. His idea is extended to the analysis of the presentational expletive construction. This paper draws a conclusion that the associate NP of the presentational expletive construction has accusative by Agree. This dichotomy (or split) is also observed in the nominative object construction in Korean. In the nominative object construction, the nominative object has nominative Case by Agree, whereas the regular object has accusative by Agree.

Alpha spectrometry was studied for the determination of $^{237}Np$ in spent nuclear fuel samples. The optimum condition for the electrodeposition of $^{237}Np$ was obtained as follows : for $1{\sim}1.5$ hour of deposition time, at the current intensity of $1.2{\sim}1.5$ A and at sodium sulfate electrolyte without organic additive. The deposition yield and its reproducibility on $^{237}Np$ was decreased as the amount of $^{237}Np$ decreased from 4.16 Bq down to 0.0264 Bq(1ng). The recovery yield of $^{237}Np$ determined by alpha spectrometry after separation in synthetic solution was $98.8{\pm}5.1%$(n=4). The contents of $^{237}Np$ in spent nuclear fuel samples were determined and the result showed an agreement within 10% of a difference between the measurement and the calculation.

Striped bitterling, Acheilognathus yamatsutae (TL: 4.25 ㎝, TW: 0.73 g)were exposed to 0.3, 1.3, 17.6 and 33.7 ㎍ L-1 (nominal concentrations) of nonylphenol (NP) for a period of 20 weeks. We studied on accumulation, growth and survival rate. After 20 weeks of exposure, the accumulation of NP in the body of the female and male was increased with increasing dose-dependent and female was higher than male. 4 weeks of exposure, TL of female striped bitterling was found to be increased in all of the dose group compared to control and 12 weeks of exposure, similar or some decreased in all of the dose group compared to control. 20 weeks of exposure, increased in all of the dose group compared to control and TL at 33.7 ㎍ NP L-1 were significantly higher than those in control (p <0.05). 4 weeks of exposure, TL and TW of male striped bitterling was found to be increased in all of the dose group compared to control and significantly higher in TL of 33.7 ㎍ NP L-1 (p <0.05). 12 and 20 weeks of exposure, TL and TW decreased in all of the dose group compared to control and significantly lower in 1.3 ㎍ NP L-1 of 12 weeks. Survival rate in both groups decreased with increasing NP concentration and there was a significant difference between control group and experimental groups exposed to each NP concentration.

The purpose of this study was to investigate the physicochemical and sensory characteristics of Noni beverages added with 10% of water(Noni 90), 1% of red ginseng(NR), 4% of rubus coreanus extract(NR), 5% of pomegranate extract(NP), and 4% of rubus coreanus extract and 5% of pomegranate extract(NPR). Calories, protein and total fiber contents were increased in NR, NP and NPR. Total sugar was significantly increased in NG and NPR. Fat, cholesterol and saturated fatty acid were not detected. Ca and Na contents were increased in NG while Fe content was increased in NG, NR, and NPR pH was significantly increased in NG and NP. Sugar degree was significantly increased in NP and NPR. L and b values were decreased in NG, NP, and NR and a value was increased in NG and NR General bacteria count was 0/mL, and Coliform, E. Coli and 0157:H7 were gram(-) in all beverages. In sensory evaluation, color was increased in NPR while taste and overall quality were increased in NG, NR and NP. Sour taste, sweet taste, and flavor were not different between Noni and the mixed beverages. Texture was significantly increased in NP and NPR. Therefore, mixed Noni beverages added with red ginseng, rubus coreanus extract, and pomegranate extract were better than Noni beverage.

This study was carried out to survey the pollution of nonylphenol (NP) in surface sediments around Gwangyang bay and Yeosu sound. NP was suspected chemicals as endocrine disruption. Gwangyang bay is located on the mid south coast of Korea. It is a semi-closed bay which Yeosu petrochemical industrial complex, POSCO (Pohang Steel Company) and Gwangyang container harbor are there. The surface sediments were collected at 15 stations with gravity corer at October, 1999, February, May and August, 2000. Also, the stream and intertidal sediment were collected at 5 sites at August, 2000. Concentrations of NP in surface sediments were in the range of 6.89 to 202.70 ng/g dry wt.. Seasonal range (mean value) of NP is 13.98 to 30.48 (23.46) ng/g dry wt. at October, 10.35 to 54.91 (28.10) ng/g dry wt. at February, 29.05 to 202.70 (82.32) ng/g dry wt. at May and 6.98 to 83.40 (25.37) ng/g dry wt. at August. NP was seasonally fluctuated, and the highest mean value and range was detected at May, 2000. NP was highly distributed in the inner part of Gwangyang bay than Yeosu sound. Concentrations of NP in stream and intertidal sediments showed the highest value in downstream near Yeosu petrochemical industrial complex and Yondung stream. It suggests that the source of NP is industrial wastewater and municipal sewage.

Biomonitoring of nonylphenol (NP), an endocrine disrupting chemical, is required in Korea to perform its proper regulation. Thus, we analyzed exposure levels of nonlyphenol (NP) in breast milk from the mothers who delivered babies within 10 days (N=325). We analyzed free and total forms of NP in breast milk with LC/MS/MS (LOD, 0.5 ppb). In addition, we obtained questionnaires concerning lifestyle from the subject. As results, ranges of total NP were ${\mu}g/L$ (median, $3.51{\pm}4.98{\mu}g/L$ vs. normal, N=281, $2.07{\pm}3.76{\mu}g/L$; p<0.05). In conclusion, we suggest that exposure monitoring of NP should be continuously performed, even though the risks of NP are not clear, yet.

Nonylphenol (NP) is a widespread environmental pollutant that has been shown to exert both toxic and estrogenic effects on mammalian cells. As the effects of NP on the reproductive system of adult male vertebrates are virtually unknown, we investigated not only the changes of reproductive hormone secretion in serum after chronic exposure to NP but also, in order to identify the site of its action, the reproductive hormone secretion in serum 48 hours after microinfusion of NP within hypothalamic preoptic area (POA). In the chronic exposure, the luteinizing hormone (LH), follicle stimulating hormone (FSH), and testosterone in serum were decreased but prolactin (PRL) concentrations were increased. The LH, FSH, and testosterone in serum were decreased through the direct infusion of NP into POA, while there was no difference in mean serum prolactin between NP and control groups. These observations suggest that NP as endocrine disruptor has modulatory effects on hypothalamo-pituitary-gonadal axis and that the site of action of NP could be hypothalamic POA.

본 연구는 환경호르몬(endocrine disruptors)으로 분류되었으며, 에스트로젠 화합물의 특성을 지닌 4-Nonylphenol (NP)이 설치류 Pituitary 세포 중 성장호르몬을 분비하는 GH3 세포의 Nitric oxide(NO)을 증가시키는 작용기전을 규명코자 수행되었다 먼저 GH3세포에 NP처리 농도에 따른 NO의 생성을 측정한 결과 NP처리농도 의존적으로 증가시켰다. 이러한 NO의 증가가 genomic action인지를 확인하기 위해 GH3세포의 NO를 증가시키는 효소인 neuronal oxide synthase의 단백질량을 측정한 결과 GH3세포에서 NP에 의한 nNOS의 단백질의 변화는 없었다. 에스트로젠 화합물인 NP가 에스트로젠 리셉터 (ER)와의 관계를 조사하기 위해 ER억제제(ICI 168,780)클 처리한 경우 NP에 의해 증가한 NO가 감소하였다. 또한 유전자 전사억제제인 actinomycin D 및 단백질 발현 억제제인 cycloheximide을 처리한 경우는 NP에 의한 NO 증가억제효과가 없었다. 이러한 결과를 종합해 볼 때 GH3 세포에서 NP는 ER을 매개한 non-genomic action에 의해 NO를 증가키는 것으로 사료된다.
