Objectives: This study aims to examine if a garbage dumping site has real and negative influence on the quality of life (QOL) for the nearby residents. The net effects of the residential distance from the garbage dumping site and from the garbage truck route were investigated for five domains of the QOL. Methods: Two hundred fifty seven Shin-dong Myeon residents, Chun-cheon Si, participated in a self-administrated survey. The Shin-dong Myeon garbage dumping site began operating in 1996. ANCOV A with generalized linear models and multiple regression analysis were performed. Results: Descriptive analyses show that a residence nearby a garbage dumping site is negatively associated with the physical and environmental domains of the QOL. The residential distance from the garbage truck route does not exert any significant effect on various domains of QOL, except for the environmental domain. On the multivariate analysis, the residents living near the garbage dumping site tended to have a significantly negative QOL in the physical and environmental domains. However, the distance from the garbage truck route did not show a significant nor substantial effect on the QOL. The demographic and socioeconomic control variables are associated with a number of the QOL domains, and their patterns are consistent with the general expectations. Conclusions: The results indicated that a garbage dumping site is considered to be an environmental hazard among the nearby residents according to the lower scores on the physical and environmental domains of the QOL. The findings from this study provide comprehensive understanding on the residents' QOL, and they may help politicians and policy makers make decisions for appropriate interventions.

저임금 여성노동자'와 노동시장 담론

신경아 이화여자대학교 한국여성연구원 2005 여성학논집 Vol.22 No.2

본 연구는 1960년대 이래 한국 여성노동자의 저임금이 어떤 담론적 기제를 통해 정당화되고 재생산되어 왔는지를 규명하는 데 목적이 있다. 연구 결과, 저임금 여성노동자를 재생산해 온 담론적 기제는 세 가지로 나타났다. 첫째, 여성노동의 범주적 단순화, 둘째, 여성노동자의 범주적 미성년화(未成年化), 셋째, 기혼여성노동자의 잔여 범주화이다. 이러한 담론들은 1960-1970년대 '기아임금'이라고 불린 여성의 임금수준을 압박하고, 그것을 정당화했던 이념적 요소들이다. 그러나 여성노동은 다른 산업노동과 마찬가지로 일정한 숙련과 작업 지식, 경력이 필요한 노동이며 여성노동자의 다수는 20세 이상의 성인노동자였다. 또한 '주부인력'으로 불리는 기혼여성노동자들은 '경력을 가진 복직노동자'로 보아야 한다. 따라서 기존의 저임금 여성노동자를 재생산한 담론들을 해체하기 위해서는 여성노동의 역사에 대한 비판적 재해석이 필요하다. This paper aims to answer the following question: "What have been the discursive mechanisms for reproducing women's low wages in the Korean labor market since the 1960s?" In spite of a great deal of debates, the low wages of women workers and the wage gap between genders did not improve during the 1970s. It seemed that some discursive mechanisms worked to effectively justify and reproduce low wages of women. Those discourses were related to the conceptual simplification of women's work, the categorization of 'being under age', as well as the residual categorization of married women workers. However, in reality, the majority of women workers was semi-skilled or skilled, and these women were not minors. And the fact is that married women workers possessed a lot of job and career experience to be considered skilled workers. Thus, the devaluation discourses contributed to the lowering of the wage level of women workers and reproduction of their low wages. In order to dismantle the negative effects of those discourses, we need to revisit the history of women's work in the light of women's experiences and feminist perspectives.

문아윤,신경훈,석동우 한양대학교 이학기술연구소 2004 이학기술연구지 Vol.7 No.

진해만 두 정점의 자기특성과 대자율의 비교를 바탕으로 하여 중금속 농도 변화가 자화강도 변화에 미치는 영향을 있는지를 살펴보았다 이를 위해 깊이에 따른 중금속 농도 변화 (산화환원 환경) 그리고 유기물' 의 함량을 조사하였다 본 연구에서는 5가지의 중금속(Al, Fe, Cr, Ni, Mn)의 농도가 측정되었으며, 자화강도와 중금속의 농도 변화는 대체적으로 유사한 경향을 나타내었고, 산화환원환경에서 각각 중금속과 자화강도의 상관성이 다르게 나타났다. 산화환경에서는 반대되는 경향을 보이고, 환원환경에서는 비슷한 상관성을 나타낸다. 총유기물(TOM)과 대자율을 비교해 보면 두 정점의 유기물 농도가 다르게 나타나며, 산화환경에서 반대되는 경향성을 나타내고, 환원환경에서 비슷한 경향을 보인다. 이것은 산화환원 환경에 따라 유기물 함량과 중금속 의 존재형이 변화하므로 서로 연관성이 있다고 생각된다. The impact of heavy metal concentrations on magnetization compared to magnetic susceptibility is investigated by the measurements of heavy metals (redox change) and organic matter contents in the sediment core samples at two stations of the Jinhai Bay. In the present study, five heavy metals (Al, Fe, Cr, Ni, Mn) concentrations were determined, and indicated generally similar trends with the corresponding magnetization. The relationship between heavy metal concentration and magnetization depend on redox-environmental conditions, showing negative correlation under the oxidation environment and positive correlation under reduction environment, respectively. Comparing total organic matter content with magnetic susceptibility, organic matter contents at both stations are different, and showed a opposite trend against magnetic susceptibility in oxidation parts, and a similar pattern in reduction parts. These results demonstrate that both organic matter contents and heavy metal speciation are influenced by redox-condition.

이경재,김형아,신민정,성재혁,박정일,한훈,이세훈 대한산업의학회 2001 대한직업환경의학회지 Vol.13 No.3

목적 : 스티렌, 하이드필퀴논 및 트리클로로에틸렌 (TCE)이 사람의 stem cell과 human myeloperoxidase (MPO)에 의해 대사성 활성화되는 지를 규명하고자 스티렌, 하이드로퀴논 및 TCE에 사람의 stem cell 또는 MPO 효소의 첨가가 이들 화학물질에 의한 자매염색분체교환(SCE)과 소핵체 (MN) 빈도에 미치는 영향을 관찰하였다. 방법 : 건강한 남자의 전혈에서 림프루를 분리하여 72시간동안 이중배양하되 배양개시 24시간만에 0.05mM 하이드로퀴논, 1.50 mM 스티렌, 혹은 1.50mM TCE를 전체용량이 30 ㎕가 되도록 아세톤에 희석하여 배양액에 주입하였고 대조군은 아세톤으로 처리하였다. 화학물질 처리 후 즉시 1.3×106 및 2.6×106 cells/ml 농도의 제대혈액으로부터 나온 stem cell 세포액의 상층액이나 1.0 및 2.0 unit의 human myeloperoxidase를 H2O2와 함께 첨가하였다. SCE분석을 위한 배양액에는 배양종료 2.5시간 전에 colchicine을 가한 후 수확하여 Giemsa염색을 하여 metaphase 세포에서 SCE빈도를 분석하였다. MN분석을 위한 배양액에는 배양개시 44시간만에 cytochalasin-B를 가하였고 acridine orange 염색 후 이핵체에서 MN수를 분석하였다. 결과 : 1. stem cell이나 MPO 자체는 SCE나 MN의 빈도에 영향을 미치지 않았다. 2. stem cell이나 MPO는 스티렌에 의해 유도되는 SCE의 빈도를 용량-반응관계로 유의하게 증가시켰고, MN빈도의 경우 step cell이나 MPO에 의해 증가되는 경향이 있었으나 2.0 unit MPO를 첨가한 경우에만 첨가하지 않은 경우에 비하여 유의하게 증가하였다. 3. 하이드로퀴논은 stem cell이나 MPO가 없는 상태에서도 대조군에 비하여 SCE빈도가 대조군에 비하여 높았다. stem cell이나 MPO는 하이드로퀴논에 의한 SCE 빈도를 용량 반응관계로 유의하게 증가시켰지만, MN의 경우에는 증가시키는 경향만 있을 뿐 유의한 차이는 아니었다. 4. TCE자체는 SCE나 MN빈도를 증가시키지 않았다. stem cell은 1.3 ×106 및 2.6 × 106 cells/ml 농도 모두에서 SCE빈도를 유의하게 증가시켰고 MPO는 2.0 unit농도에서만 유의하게 증가시켰다. stem cell이나 MPO모두 TCE에 의한 MN빈도를 증가시키는 경향이 있었으나 유의한 차이는 아니었다. 결론 : 저자들은 스티렌, 하이드로퀴논, 및 트리클로로에틸렌에 의해 유도되는 자매염색분체교환과 소핵체의 빈도가 사람의 stem cell이나 myeloperoxidase에 의해 증가됨을 발견하였으며, 이러한 결과는 myeloperoxidase가 이들 물질의 대사성활성화에 관여함을 암시하고, 또한 아마도 이 물질들의 골수독성과 관련이 있는 것이라고 제시된다. Objectives : The objective of this study was to identify the possible role of stem cell and myeloperoxidase (MPO) in the metabolic activation of styrene, hydroquinone and trichloroethylene, by investigating the effects of stem cell from umbilical cord blood and MPO on the frequency of sister chromatid exchange (SCE) and micronuclei (MN) induction in cultured human peripheral lymphocytes exposed to hese chemicals. Methods : Islated lymphocytes from whole blood were cultured for 72 hours. The cells were treated with 1.50 mM styrene, 50 μM hydroquinone and 1.50 mM trichloroethylene dissolved with acetone (30㎕ in total volume) at 24 hours after the beginning of culture. Control group was treated with acetone only. Immediately after adding these chemicals, 1.3×106 cells/ml and 2.6×106 cells/ml stem cell/ml stained with Giemsa's solution, and acridine orange for sister chromatid exchange, and for micronucleus analysis, respectively. Results : The results were as follows: 1) Myeloperoxidase and stem cell did not significantly affect the frequencies of SCE or MN in the control group. 2) The frequency of SCE or MN with exposure to styrene did not different from control in the absence of stem cell or MPO. Sister chromatid exchange induced by styrene was significantly increased by adding stem cell or MPO in dose-dependent relationship. The frequency of MN induced by styrene significantly increased in the presence of 2.0 unit MPO. 3) The frequency of SCE was significantly increased with exposure to hydroquinone than acetone treated control in the absence of stem cell or MPO. Sister chromatid exchange induction by hydroquinone significantly increased dose-dependently in the presence of stem cell or MPO. There was a tnendency of increase of the MN frequency induced by hydroquinone in the presence of stem cell or MPO, but not significant. 4) It was found that trichloroethylene itself did not increase SCE or MN frequency. Frequency of SCE induced by trichloroethylene was significantly increased with adding stem cell (low and high) and 2.0 unit MPO. Even though them cell or MPO increased the frequency of MN of lymphocyte exposed to trichloroethylene, the difference was not significant. Conclusions : Authors found that the frequencies of both sister chromatid exchange and micronucleus induced by styrene, hydroquinone, and trichloroethylene were increased significantly with the treatment of stem cell or myeloperoxidase. It was suggested that myeloperoxidase may therefore play an important role in the metabolic activation of styrene, hydroquinone, and trichloroethylene and myeloperoxidase probably be involved in the myelotoxicity of these chemicals.

천근아,이경숙,신의진 대한신경정신의학회 2001 신경정신의학 Vol.40 No.1

연구목적: 아동 학대 또는 방치와 같은 병적인 양육환경이 신경생물학적인 변화를 야기할 수 있다는 가정하에, 심각한 주양육자와의 애착관계의 문제를 보이는 아동들을 대상으로 SPECT를 이용한 뇌 혈류 양상을 알아보고 뇌의 비정상 소견 여부를 관찰하고자 한다. 방법: 연구대상은 반응성애착장애(reactive attachment disorder)로 진단된 2∼6세 아동 12명으로 구성되었다. 진단도구로서 DSM-IV, ICD-10, 낯선상황절차(Strange Situation Procedure), 사회성숙도 검사(Social maturity Scale), 아동기 자폐증 평가척도(Chilhood Austism Rating Scale)가 이용되었다. 진단된 모든 아동에게 SPECT 촬영이 시행되었으며 두 명의 핵의학 전문의에 의해 판독된 결과에 따라 뇌혈류 양상을 관찰하였다. 결과: 12명의 애착장애 아동중 11명이 특정 영역에서 관류(perfusion)가 감소된 비정상적 SPECT 결과를 보였다. 특히 10명은 시상(thalamus)에서 감소된 관류(perfusion) 양상을 보였으며, 이중 좌측시상의 관류감소는 6명, 우측시상의 관류감소는 1명, 양측 시상 모두 관류가 감소된 경우는 3명이었다. 기저핵 (basal ganglia)에서 관류가 감소된 아동은 총 5명으로 모두 좌측 기저핵에서 감소된 소견을 보였다. 시상과 기저핵 모두에서 관류의 감소를 보인 아동이 4명이었다. 단 한명의 아동이 두정엽에서 관류감소를 보였고, 나머지 전두엽, 측두엽, 후두엽, 소뇌 영역에서는 대상 모두가 정상적인 관류양상을 보였다. 결론: 본 연구를 통해 애착장애 아동에서 뇌 혈류 양상이 대부분 비정상적임을 알 수 있었다. 이는 영·유아들이 병적인 양육환경에 의해 뇌발달이 저해될 수 있음을 의미하며 정상적인 뇌발달을 위해서는 초기 어린 시절의 양육환경이 매우 중요함을 암시한다. Objectives : This study aimed to reveal that severe disturbance of attachment relationship with primary care-giver can affect functional brain development by measuring with technetium-99m ethyl cysteinate dimer brain single-photon emission tomography. Methods : Subjects were 12 children aged 2-6 years who met the diagnostic criteria of reactive attachment disorder. Diagnostic tools were DSM-IV, ICD-10, Strange Situation Procedure(SSP), Vineland Social Maturity Sclae(SMS), and Childhood Autism Rating Scale(CARS). Brain SPECT was performed in all sbjects and each SPECT scan was visually assessed by two nuclear medicine specilalists. Results : Eleven of 12 children had abnormal brain perfusion on SPECT scans, revealing focal areas of decreased perfusions. Perfusion of thalamus was decreased in 10 subjects -decreased perfusion of left thalamus(6/10), right thalamus(1/10), and both thalami(3/10). Perfusion of basal ganglia was decreased in 5 children. Four children had decreased perfusion of thalamus as well as of basal ganglia. Decreased perfusion of parietal area was noted in only one child on SPECT scan. All subjets had normal perfusion of frontal, temporal, occipital, cerebellar areas on SPECT scan. Conclusion : Perfusion abnormalities involving thalamus, basal ganglia in most children with attachment disorder were found in this study. These results suggest that brain development of infant could be impeded by severe pathologic care and early nurturing environment environment would be important for normal brain development.

Estradiol에 의한 흰쥐-자궁의 수축 기능과 Polyamine 대사의 변동에 관한 연구

이명아,고재홍,이영재,신경호,전보권,천연숙 고려대학교 의과대학 1995 고려대 의대 잡지 Vol.32 No.3

The polyamines have been postulated to be essential in most processes associated with both hypertrophy and hyperplasia. The effects of estrogen on uterine contractility vary with animal species, and most reports have shown that in vitro contractility of rat uterus is decreased after estrogen treatment, but estrogen increases polyamine contents in castrated rat uterus. This study was carried out to investigate whether the regulation of polyamine metabolism may be instrumental in the contractile response of castrated nonpregnant uterus of female SD rats to electrical field stimulation (40 V, 100 μsec : EFS). Estradiol (E2) increased uterine contents of putrescine (PT), spermidine (SPD), and spermine (SPM). These E2 effects were inhibited by tamoxifen or DFMO, but E2-incuced increase of uterine SPM content was enhanced by aminoguanidine. E2 decreased the amplitude of force developed in the rhythmic spontaneous contraction of rat uterus, but it exaggerated the increase of uterine contraction force in response to EFS. The E2-dependent exaggeration was inhibited by tamoxifen, DFMO, or indomethacin, but was significantly enhanced by aminoguanidine. The synergism between E2 and aminoguanidine on uterine contractility was little affected by indomethacin. These results suggest that E2-dependent increase of uterine contractility may be ascribed partly to increase of uterus polyamines.

The present study conducted focus group interviews to examine college students’ perceptions and attitudes toward energy saving on campus. These students who participated in the interviews currently lived on dormitories and using the sense-making approach, students were asked to indicate their thoughts and current energy use behaviors on campus. These students acknowledged that they were likely to waste electrical energy in terms of using PC and lighting in their dorms. They expressed their neglect in switching off electricity while they were absent from the facility. However, they felt justified with energy wasting in the dormitory because they thought they already paid enough money to the university for residential fees. Students also pointed out that the university management should take more initiative in promoting energy saving with financial compensations and conveniently engineered electricity saving tactics. Also the focus group discussions rendered a deeper understanding of the target audience and based on that understanding, energy saving campaign strategies or message strategies could be drawn.

痙攣性 腦-電氣衝擊에 의한 생쥐 視床下部 및 腦幹의 Monoamine 代謝의 變動에 관한 硏究

全普權,申炅浩,朴靑山,李明雅 大韓神經精神醫學會 1991 신경정신의학 Vol.30 No.4

Male ICR mice ranging from 15g to 20g were given a single ECS(1-ECS : 13mA, 1sec,100cps) daily or on alternate days for 10 days(5-ECS). The contents of monoamine metabolites in the hypothalamus and the brain stem(BS) were measured 10, 30. and 60 min after ECS-administration as well as before ECS. Contents of monoamine metabolites in the HT and the BS, such as 5-HIAA, MHPG, DOPAC and HVA increased rapidly after 1-ECS or 5ECS and then came down to the pre-ECS values. However, their increases induced by 5-ECS were significantly smaller than those by 1-ECS except the tedious increase of the hypothalamic HAV content. 5-HIAA and MHPG in the HT decrease significantly by the 4the administration of ECS in the course of the 5-ECS treatment. These results suggest that the repeated treatment of ECS may decrease the turnover rates of serotonin and noradrenaline in the hypothalamus.
