As crops recently can be cultivated all the year in greenhouses. we need to improve the environment in which crops are able to grow in the summer. Therefore. in this study. we quantitatively got the cooling effects of 4 single span plastic greenhouses in the following ways: by spraying mist or sprinkler. or by opening the side window. and with those variables. we simultaneously did experiments at 4 greenhouses under equivalent conditions to reduce the temperature of the greenhouses in the summer. The results of the experiments are as following : 1) The temperatures of the greenhouses were effectively reduced by both spraying mist and sprinkler. 2) When the mist is intermittently sprayed. the indoor temperature has decreased by 4 degrees centigrade. meanwhile. in the greenhouse to make experiments using sprinkler. the temperature of that has been reduced by 2 degrees centigrade. Therefore. we can see the cooling effects of smaller mist in size as more effective than those of sprinkler. 3) When the greenhouse is naturally ventilated by opening the side window. we have to apply another cooling system because the indoor temperature is higher than the outdoor one.

임숙빈,이소우,홍강의 대한소아청소년정신의학회 2000 소아청소년정신의학 Vol.11 No.2

자폐아동을 위해 개발된 모-아애착증진 프로그램의 효과를 평가하고자 참여군과 비참여군의 변화를 비교하였다. 대상자는 S대학교병원 애착증진 프로그램에 참여하는 자폐아동과 어머니 7쌍, 참여하지 않는 자폐아동과 어머니 4쌍이었다. 6개월 간격으로 2회, 비디오 촬영법 등을 통해 자료를 수집하였으며 Wilcoxon Rank(Sign) Sum Test로 모-아애착, 양육행위, 자폐적인 행동 특성의 변화를 비교 분석하였다. 그 결과 참여군의 애착행동의 변화는 같은 기간 비참여군의 애착행동의 변화보다 유의하게 컸으며 일치성을 제외한 근접성, 상호성, 정감성에서 양적으로나 질적으로 긍정적 변화를 보였다(p<.05). 접촉유지, 차별적, 애정적 행동이 크게 증가하였으나 공감적, 일치적, 합동주시 행동의 변화는 적었고 아동간에 개별차가 컸다. 아동의 성장발달을 위한 어머니의 양육행위도 참여군에서 크게 증가하였으나 그룹간 차이는 유의하지 않았다(p<.05). 애착행동의 증진은 또한 자폐적 행동 특성에 긍정적 영향을 미쳐 모-아애착 증진 프로그램이 자폐아동들의 사회적 행동의 증진 뿐만 아니라 문제 행동의 개선에도 유용한 조기 중재 프로그램으로서의 가능성을 보였다. 중심 단어 : 자폐아동ㆍ애착ㆍ모-아애착증진 프로그램ㆍ아동의 성장발달을 위한 양육행위. Objectives : This study was conducted to evaluate the effects of the attachment promotion program which was designed to promote attachment between autistic children and their mothers. The program was consisted of play activity centered mother-child interaction, educational acitivity for mothers by lecture, video-feedback session, and emotional supports. Methode : The subjects were consisted of 11 pairs of mother and child(7 for participant group : PG, 4 for non-participant group : NPG), who were 2-4 years-old autistic children. The data were collected by video-taping, behavioral observations, and analyzed by Wilcoxon Rank(Sign) Sum Test and Content Analysis. Results : The total attachment score increased from pre test to post-test of PG was significantly higher than that of NPG. The scores of attachment behaviors indicating proximity, mutuality and affect increased signiscantly(p<.05), while some behaviors indicating synchrony and joint-attention did not. Especially the affectionate behaviors of PG demonstrated the most notable changes and they became more active, voluntary and reciprocal. After the program, the mother's nurturing behavior of PG increased more than that of NPG, with no significant difference between two groups. The mother's behaviors to her child of PG became more child-centered, positively responsive, supportively expressive. As the attachment was promoted, there were also positive changes in the children's autistic behaviors with a great deal of individual differences. Conclusion : Our findings suggest that Mother-Child Attachment Promotion Program could be an effective early intervention model for autistic children. KEY WORDS : Autistic childㆍAttachmentㆍMother-child attachment promotion programㆍNurturing behavior for child's development.

Objectives : To investigate the influence of smoking, alcohol ingestion, and physical activity on copper and zinc in RBC and serum and serum ceruloplasmin, this study was performed in a cross-sectional study in 113 healthy men aged 20 to 40 years who had no symptomatic liver, heart, gastrointestinal, and other chronic diseases. Methods : At the men's entry into the study, blood samples were drawn from each subject and immediately centrifuged for analysis of copper, zinc, iron, ceruloplasmin, total cholesterol, and hematocrit. Each man completed a questionnaire that provided information on smoking, amount of alcohol intake, and physical activity. Partial regression analysis was performed on confounding variables such as age, body mass index, hematocrit, serum cholesterol, and serum iron. Results : In general linear models, adjustment for confounding variables did not show statistical differences, and there was only an increasing tendency in serum copper in heavy smoker(P=0.0678). There was no difference between high physical activity with mild smokers and lower physical with heavy smokers. Conclusions : This study suggested that copper, zinc and ceruloplasmin were not good biomarker for early effect by smoking, alcohol intake and physical activity in young adult. However, selection bias should be considered in evaluation of this result, and a large prospective study will be needed in advance on usefulness of copper, zinc and ceruloplasmin as a marker for risk factors and early change of atherosclerosis.

임홍상,국우각,강경우 한국로지스틱스학회 2002 로지스틱스연구 Vol.10 No.2

인천국제공항의 개항과 남북경협을 통한 동북아 물류중심국가로 발전하기 위하여 노력을 기울이고 있는 우리나라는 현재 물류에 대한 관심이 그 어느 때보다 높게 나타나고 있으며, DHL, UPS 같은 국제적인 전문 물류업체는 최첨단 물류정보시스템과 자산을 가지고 적극적인 국내 마케팅활동을 벌이고 있다. 우리나라의 경우 IMF라는 국가적 불황을 겪게 되면서 물류 아웃소싱에 대해 그 인식이 크게 제고되었으며, 과거 규모 위주의 성장을 추구했던 것에서 벗어나 수익성·차별성을 추구하면서 기업을 경영하는 풍토가 조성되었다. 하지만 이러한 특수성은 외국에서 나타난 아웃소싱의 순효과 외에 단순한 구조조정의 수단으로 이용되어 물류기능의 고도화가 이루어지지 않았다는 지적은 우리나라 물류아웃소싱의 방향설정 및 물류전략설정에 있어 많은 관심과 지속적인 노력을 기울여야 한다는 것을 의미한다. 본 연구는 국내 수배송 전문업체의 바람직한 마케팅전략을 세우는데 그 목적이 있었으며, 이를 시장 즉, 화주측면에서 접근하였으며, 로지스틱 판별분석을 이용하여 수배송 아웃소싱을 도입하고 있는 기업과 도입하지 않은 업체에 대해 분석을 실시하였다. 분석결과 물류 정보서비스의 활용 및 선호도가 높을수록, 화물의 시간가치가 높을수록, 공차거리율 및 적재율의 정기적인 측정이 이루어질수록, 제품의 출하빈도가 높을수록, 통행특성에 있어 TL 보다는 LTL 일수록 수배송 아웃소싱을 선호하는 것으로 나타났다. 특히, 국내의 제3자 물류공급업체 및 화물운송업체의 경우 상대적으로 물류정보시스템에 대한 중요도 및 위탁업체와의 상호 호환성에는 그 중요도가 낮은 것으로 나타나 본 연구의 분석결과에 비추어 볼 때 하루바삐 인식의 전환 및 구축이 필요할 것이라 판단된다. Recently, Korea has a great concern of the logistics. Expecially opening of the Incheon International Airport and planning for a major role in logistics in the East-Asia region through improving in inter Korean relation accelerate their logistics concern. Futhermore, international freight delivery service provider such as DHL & UPS sales positively with their state of arts logistics information services and asset. In case of Korea, many company managed from the pursuit of scale economy to focus on a core business and cost saving as recognized for outsourcing of the logistics function when the economy of Korea was under an IMF bailout program. However, their point of view is not by positive effects such as specific competitive power of speciality but used of reshaping in labour force. The objective of this study is build a marketing strategies of freight delivery service in Korea. Particularly, this study is by Logistics Discrimination analysis between those who shipper with outsourced their delivery service and are not. As the result of analyzing outputs from Logistics Discrimination model, those who more used outsourced in freight delivery service when delivery service are the more employing information services related to logistics such EDI etc, handle with higher value of time(VOT) in freight, regularly check up the rate of travels with(without) freight, the shipment is more frequent, and less than truck-load(LTL) in trip characteristics.

林洪雨,姜錫奉 대한한방종양학회 1998 대한한방종양학회지 Vol.4 No.1

It has been known thal "Gobongeonvangdan" has a certain effects on male sterility in the field of oriental medicine. this thesis purposes to prove such effects of the medicine especially concerning sex hormones and hematorgenesis. In the study were used three groups of rats: two of those were treated with Gobongeonyangdan with a variety of quantity and the other untreated. The experiment spans for 35 days: lests upon those subjects were done three times on the 7th. 21st, and 35th day checkin the change of testosterone, estradiol, LH, FSH and iton in the serums. RBC. hematocrit and hemoglobin levels. The results obtained from the study are as follows: 1. The content of testosterone in the serums marked a significant incrase in both treated groups in comparison to the untreated group. 2. The coment of estradiol in the serums showed a signinficant increase in the treted groups as to the untreated. 3. The coment of LH in the serums increased signifieantly in the treated groups as to the untreated. 4. The coment of FSH in the serums also mcreased remarkably in the two treated groups as to the umtreated. 5. The content of iron in the serum was seen to be increased in the treated groups rather than the untreated group. 6. The RBC was observed to show a tendency toward a signilicant in crease in both the treated groups in comparison with the untreated group. 7. The hemoglobin levels were also increased significantly in the treated groups as to the untreated. 8. The hematocrit levels were decreased significantly in one of the two treated group(sample A group)and thacre was no difference in the other group(sample B group) in comparison with the untreated group. Consequently, "Gobongeonyangdan" may well be a facorable medicine for patients who have sexual functional disorder and it is also effective on hematogenesis.

최홍열,고상백,장세진,차봉석,임형준,이상윤,김재용,강동묵,조수헌 大韓産業醫學會 2001 대한직업환경의학회지 Vol.13 No.1

목 적 : 하청노동을 이용한 노동 유연화 전략은 근로자들의 고용을 불안정시키고, 근로자들의 삶에 부정적 영향을 미치고 있다. 따라서 이 연구는 하청업체 근로자들의 고용현황을 조사하고, 기존의 업체중심의 건강평가의 문제점을 지적하고자 하였다. 또한 하청업체 근로자들의 건강평가의 현재적 의미와 사회적 배제의 특성을 알아보고자 하였다. 방 법 : 모기업과 하청업체 근로자들의 건강수준을 비교하기 위하여, 정기건강진단(일반, 특수)과 채용건강진단 자료를 이용하고자 하였다. 건강진단에서 누락된 비정규직을 포괄하기 위하여 SF-36을 이용하여 건강설문조사를 시행하였다.결 과 : 조선업 하청업체 근로자들의 고용기간은 짧고, 빈번한 노동이동 현상을 보였다. 3년간 건강진단 수검 현황을 통해 살펴볼 때, 1998년 수검자중 2000년까지 연속해서 검진 받은 수검자는 40.3%였다. 건강진단 결과 유소견자 규모를 통해 모기업과 하청업체간의 건강수준을 비교해 보았다. 모기업은 일반질병 요관찰자와 질병자를 포함한 유소견자가 1,011명으로 약 10 %의 유소견율을 보이고 있고, 질병자의 경우 596명으로 유병률이 5 %를 상회하고 있다. 반면 하청업체의 경우 1,967명의 수검자중 유소견자가 115명으로 6 %의 유소견율을 보이고있고, 질병자는 82명으로 4 %의 유병률을 보이고있다 채용건강진단을 받은 수검자는 6,260명 이었으며, 이 중 유소견자 수는 2,373명으로 전체 수검자의 37.9 %를 차지하였다. 건강설문지의 경우는 전체 건강수준의 총합은 하청보다 원청 근로자가 높았고 통계적으로 유의하였다. 결 론' 정기건강검진 결과는 하청근로자들이 고용형태에 따라 검진을 받지 못한 경우가 많아, 건강 근로자 효과로 표현될 가능성이 있다. 따라서 채용건강진단 결과는 다른 측면에서 하청업체 근로자들의 건강수준의 현실적 반영이라고 할 수 있다. 향후 하청업체 근로자들의 건강문제를 감시하고 개선하려면 기존의 업체 중심의 접근으로는 하청 근로자의 건강문제를 제대로 다룰 수 없고, 업종과 지역을 동시에 고려하여 접근할 필요가 있다. 또한 단기 고용 근로자 및 비정규직 근로자를 사회보장의 확충과 모기업의 연대책임 강화 및 기업복지 차원에서 포괄하는 방안이 모색되어야 하겠다. Objectives : The strategy for the labor flexibility through subcontracted labor have brought a negative effect on the lives of the workers, such as the increase of the unstable employment. This study was conducted to analyze the relationship between the employment of subcontracted firms and the health status of them, and to find out some problems which have been caused in the process of health evaluation and the characteristics of social exclusion. Methods : We reviewed the periodical health examination and preemployment health examination in order to compare health status of the subcontracted workers with those of the parent firm workers. The SF-36 questionnaire was administered to assess the self-perceived health status. Results : The result shows that compared to the working duration of the parent firm workers, those of the subcontracted workers were shorter, and the job transfer rate was higher. In the periodical health examination, the prevalence of occupational and general disease was higher in the parent firm(10%) than in the subcontracted firms(6%). Preemployment health examination plays an important role in worker's health manage- ment. Among 6,260 workers who received preemployment health examination, the prevalence of disease was 37.9%. Mean scores of health status measured by SF-36 were lower in the subcontracted firm than in the parent firm. Conclusions : Due to social exclusion of the subcontracted workers from the periodical health examination, there is a possibility that the periodical health examination have the healthy worker effect. These results suggests that the preemployment health examination could be a more appropriate indicator which is able to assess the health status of the subcontracted workers than the periodical health examination.

Major cardiovascular complications of diabetes are coronary atherosclerosis, diabetic dilated cardiomyopathy, autonomic neuropathy and those are major causes of morbidity and mortality in diabetic patients. Gated blood pool heart scan is noninvasive and useful method for evaluation of functional status of heart in diabetics. We evaluated 52 patients with diabetes and divided 3 groups. Group 1 were 11 patients without proteinuria or with proteinuria less than 550mng during 24 hours. Group 2 were 9 patients with proteinuria more than 550mg during 24 hours and group 3 were 32 patients with endstage renal diasese due to diabetes. We performed 99mTc-HSA cardiac gated blood pool scan and used left ventricular ejection fraction(LVEF), peak ejection rate(PEF) to indices of LV systolic function and peak filling rate(PER) to index of LV diastolic function. The results were follows : 1) LVEF, PER were significantly lower in diabetics with ESRD than diabetics without ESRD, but there were no significant difference between normal controls and diabetics without ESRD 2) PFR was significantly lower in diabetics than normal controls, but there were no significant differences in diabetics with or without nephropathy. 3) There were negative correlation between PER, PFR and duration of diabetes. On the basis of results, PFR is a LV functional index of GBPS which can disclose early change of LV dysfunction in patients with diabetes.

기능성 Catechol-O-Methyltransferase 유전자 다형성과 한국인 정신분열병의 관련성

연구목적 : Catechol-O-Methyltransferase(COMT)는 카테콜아민 신경전달물질의 불활성화를 담당하는 효소로서, 정신분열병과 관련된 후보 유전자로서 알려져 왔다. 최근, 기능성 COMT유전자 다형성과 정신분열병의 관련성이 제기되었는데, 한국인 정신분열병에서도 이러한 관련성이 있는지를 살피기 위해 본 연구를 시행하였다. 방 법 : 정신분열병으로 진단된 환자군 103명과 성별 및 연령별로 1:1 짝짓기 대조군 사이에 유전자형과 대립유전자의 분포를 비교하였다. 또한, 환자군은 공격적 행동, 가족력, 아동기 발병 여부에 따라 두 군으로 나누어 비교하였다. DNA의 다형성 부의를 중합효소연쇄반응에 의해 증폭한 후 ,NlaⅢ제한효소법과 전기영동을 실시하여 유전자형을 판별하였다. 결 과 : 환자군 전체와 대조군 사이에 유전자형과 대립유전자 빈도의 차이가 없었다. 가족력이 있는 환자군을 대조군과 비교하였을 때는, 대립유전자 L을 포함하는 유전자형과 그렇지 않은 유전자형의 분포에 있어 유의한 차이를 보였다(p=0.02, OR=3.9, 95% Cl=1.1∼14.3). 결 론 : 한국인 정신분열병과 기능성 COMT 유전자 다형성 사이에 유의한 관련성이 없었다. 따라서, 기능성 COMT 유전자 다형성이 한국인 정신분열병의 발병에 영향을 주지 못한다. 그러나, 정신분열병 가족력과 기능성 COMT유전자 다형성의 관련성이 시시돠어, 향후 본 연구에서 나타난 방법론적인 문제점을 보완하고 추가 대상자를 확보한 연구가 필요하다. Objectives : Catechol-O-methyltransferase(COMT) is involved in the degradation of catecholamine meurotransmitters and has been investigated as a candidate gene in schizophrenia. Recently, possible relationship between functional COMT gene polymorphism and schizophrenia has been suggested. To address the possible role of functional COMT gene polymorphism in the predisposition to schizophrenia, we carried out an association study in Korean schizophrenic patients and controls. Methods : One hundred and three Korean inpatients diagnosed as schizophrenia and 103 age and sex matched controls were selected as study subjects. Patients were subgrouped into two groups on the basis of history of aggressive behavior, family history of schizophrenia and related disorders, and age at onset. We determined COMT genotypes using PCR of the relevant region followed by digestion with NlaⅢ and electrophoresis. Results : No significant differences of allele and genotype frequencies were noted between patients and controls. However, when patients were categorized by the presence of family history of schizophrenia and related disorders, patients with family history showed almost 4 fold higher frequency of having COMT L allele containing genotype compared to controls(p=0.02, OR=3.9, 9.5% CI=1.10-14.33). Conclusion : Although our results do not support an association between functional polymorphism of COMT gene and schizophrenia overall, the findings suggest an association between functional COMT gene polymorphism and familial schizophrenia. Further studies with large samples are needed to confirm this association.
