The influences on water quality of each river by effluents from environmental facilities located in 14 unit watersheds of North- and South-Han River, and Gyungan-cheon were analyzed. Also, the water quality modeling for study area was carried out to analyze the improvement effect of water quality by the strengthening of T-P effluent standard of environmental facilities. For the calibration and verification of model, water quality data and effluent loading calculated for 2006 were used. Data of low water period were used for calibration, and normal water period for verification. The results of calibration and verification were well matched with the real water quality dataset of revers. Also, the validity of the results were estimated using RI(Reliability Index) method. When the T-P effluent standards for environmental facilities were strengthened, T-P concentrations were predicted to improve from 0.025㎎/ℓ to 0.023㎎/ℓ in the outlet location of North-Han River, from 0.056㎎/ℓ to 0.040㎎/ℓ for South-Han River, and from 0.233㎎/ℓ to 0.146㎎/ℓ for Gyungan-cheon. Also, the T-P concentrations of tributaries including Jojong-cheon, Dal-cheong, Sumgang, Chungmi-cheon, Bokha-cheon, Heuk-cheon, and Wonju-cheon were predicted to improve from 0.063㎎/ℓ to 0.010㎎/ℓ, from 0.091㎎/ℓ to 0.053㎎/ℓ, from 0.199㎎/ℓ to 0.100㎎/ℓ, from 0.168㎎/ℓ to 0.148㎎/ℓ, from 0.186㎎/ℓ to 0.105㎎/ℓ, from 0.019㎎/ℓ to 0.013㎎/ℓ, and from 0.822㎎/ℓ to 0.236㎎/ℓ, respectively.

Objectives : To see if there were any differences in waist circumference reduction when certain variable such as age, sex, BFR(BFR; Body Fat Rate), PIBW(PIBW; Percent Ideal Body Weight), WHR(WHR; Waist Hip Ratio) and BMI(BMI; Body Mass Index) were given. Methods : Among outpatients who admitted to department of Oriental Rehabilitation Medicine, Jeon-Ju Oriental Medicine Hospital, Won-kwang University from August 2003 to september 2004, 89 obese patients were chosen and electroacupunture was practiced to these groups in order to treat abdominal obesity and waist circumference reduction. Results : There were no significant correlation between sex, age and waist circumference reduction. Compared to groups who had shown lower BMI, higher BMI groups have shown greater change in waist circumference reduction. As BFR increase waist circumference reduction tended to increase as well. Conclusions : From the above results, higher BMI groups had shown greater change in waist circumference reduction compared to lower BMI groups.

물류산업의 국민경제적 파급효과 분석

정동원 ( Dong Won Jeong ),한종호 ( Jong Ho Han ) 한국물류학회 2012 물류학회지 Vol.22 No.2

물류산업은 경제 발전에 중요한 역할을 담당하며, 산업경쟁력과 국가경쟁력을 결정하는 중요한 요소로 작용하고 있다. 본 논문에서는 산업연관분석을 이용하여 물류산업의 국민경제적 파급효과를 분석하고자 한다. 먼저 수요유도형 모형을 이용하여 물류산업의 타 산업 생산유발효과, 부가가치 유발효과, 취업유발효과를 살펴본다. 다음으로 상대적으로 복잡성 때문에 잘 사용되지 않았던 공급유도형 모형 및 레온티에프 가격모형을 적용하여 물류산업의 공급지장효과 및 물가파급 효과를 살펴본다. 이러한 분석은 모두 물류산업을 내생부문이 아닌 외생부문으로 다룸으로써 물류산업을 중심으로 이루어지게 된다. 주요 분석결과를 요약하면 다음과 같다. 물류산업의 1원 생산은 타 산업의 생산을 0.5104원만큼 유발하며, 타산업의 부가가가치를 0.1722원만큼 유발한다. 또한 물류산업의 10억원 생산은 타산업에서 2.2554명의 취업을 유발한다. 한편 물류산업에서 1원의 공급이 이루어지지 못할 때, 타 산업에서는 0.9387원의 생산차질이 발생하여 공급지장효과가 제법 큰 편이다. 마지막으로 물류산업의 가격이 10& 상승했을 때, 국민경제 전체적으로 미치는 물가파급효과는 0.0276%로 분석되었다. The logistics industry in Korea plays a major role in the national economy development and to make decision nation and industrial competitiveness, This study attempts to examine the economic impacts of the logistics industry using an inter-industry analysis, Specially, the study investigates production-inducting effect, value added inducing effect, and employment-inducing effect of the logistics industry based on demand-driven model. Moreover, the study deals with supply shortage effect and sectoral price effect by using supply-driven model and leontief price model, respectively, which have been rarely used because of their complications involved in computaiton. These analyses pay particular and close attention to the distribution industry by taking it as exogenous rather than endogenous. Some interesting findings emerge from the study. First, the production of 1.0 won in the logistics industry induces the production of 0.5104 won and the value-added of 0.1722 won in other industries. Second, the production of 1.0 billion won in the logistics industry causes the employment of 2.554 persons in other industries. Third, the supply shortage of 1.0 won in the logistics industry disables other industries to produce 0.9387 won. Finally, an increase of 10% in price level of the logistics industry raises the overall price level by 0.0276%.

연구목적 : 본 시험의 목적은 임상시험 시작전에 연구자들을 대상으로 PANSS Workshop을 통하여 PANSS, ESRS에 대한 국내에서의 표준화 작업을 구축하고 새로운 정신병 치료제인 리스페리돈의 효과와 안정성을 재확인하여 리스페리돈 사용에 대한 적정화를 이루는데 있다. 연구방법 : 1996년 4월부터 1996년 9월까지 국내 39개 대학병원 정신과에 입원중인 혹은 증상이 악화되어 입원하는 정신분열병 환자 377명을 대상으로 다시설 개방 연구를 시행하였다. 1주일간의 약물 배설기간을 가진후, 리스페리돈을 8주간 투여하였고, 기준점, 1주, 2주, 4주, 그리고 8주후에 평가되었다. 용량은 제1일에는 리스페리돈 1mg씩 1일 2회, 제2일에는 2mg씩 1일 2회, 제3∼7일에는 3mg씩 1일 2회 투여하였다. 이후 환자의 임상상태에 따라 임의로 증량할 수 있으며, 최대 일일 16mg을 초과하지 않도록 하였다. 추체외로 증상을 조절하기 위한 투약을 허용하였다. 임상증상 및 부작용의 평가는 PANSS(Positive and Negative Syndrome Scale), CGI(Clinical Global Impression) 그리고 ESRS(Extrapyramidal Symptom Rating Scale)을 사용하였다. 연구결과 : 377명중 343명(91%)이 8주간의 연구를 완결하였다. 치료 종결시점인 8주후 PANSS 총점수가 20% 이상 호전된 경우를 약물 반응군으로 정의할때, 약물반응군은 81.3%였다. 리스페리돈에 반응하는 예측인자로는 발병연령, 이전의 입원 횟수, 유병기간이 관련 있었다. 리스페리돈은 1주후부터 PANSS양성, 음성, 및 일반정신병리 점수상에 유의한 호전을 보여 효과가 빨랐다. CGI의 경우도 기준점에 비해 1주후부터 유의한 감소를 나타내었다. ESRS의 경우, 파킨슨 평가점수는 기준점과 비교해 투여 1주, 2주, 4주후 유의하게 증가되었다가 8주후 기준점과 차이가 없었다. Dystonia 평가점수는 1주후만 유의한 증가를 보였으며, dyskinesia 평가점수는 유의한 차이가 없었다. 혈압, 맥박수의 생명징후 및 일반 혈액학 검사, 생화학적 검사, 심전도 검사에서 유의한 변화는 없었다. 결 론 : 이상의 다시설 개방 임상 연구를 통해 리스페리돈은 정신분열병 환자에서 양성증상뿐만 아니라 음성증상 및 전반적인 증상에도 효과적인 것으로 사료된다. 보다 명확한 평가를 위해서는 다른 항정신병약물과의 이중맹검 연구가 필요할 것으로 생각되며, 또한 장기적 치료에 대한 평가도 함께 이루어져야 하겠다. Objective : The purpose of this study was to investigate the efficacy and safety of risperidone in the treatment of Korean schizophrenic patients. Method : This multicenter open study included 377 schizophrenic patients drawn from 39 university hospitals. After a wash-out period of 1 week, the schizophrenic patients were treated with risperidone for 8 weeks and evaluated at 5 points ; at baseline, and 1, 2, 4 and 8 weeks of treatment. The dose was increased from 2mg/day(1mg twice daily) to 6mg/day(3mg twice daily) during the first week and adjusted to a maximum of 16mg/day over the next 7 weeks according to the patient's clinical response. Medication to control extrapyramidal symptoms was permitted. The psychiatric and neurological status of the patients was assessed by PANSS, CGI, and ESRS scales. Results : 343(91%) of 377 patients completed the 8-week trial period. Clinical improvement, as defined by a 20% or more reduction in total PANSS score at end point, was shown by 81.3% of patients. The predictors of response to risperidone were associated older age, shorter duration of illness, fewer previous hospitalization. Risperidone had rapid onset of action ; a significant decrease of the total PANSS and three PANSS factor(positive, negative, general), and CGI was already noticed at the end of first week. For the ESRS, parkinsonism rating scores were significantly increased until week 4 comparing with baseline. Dystonia rating scores were significantly increased until week 1, and dyskinesia rating scores were not significantly changed during the study. Laboratory parameters including vital sign, EKG, hematological, and biochemical values showed no significant changes during the trial. Conclusions : This study suggests that risperidone is generally safe and effective against both the positive and negative symptoms in our group of patients.

연구목적 : 1998년 정신건강의 날 기념 한국인 우울증 선별의 날 행사에 자발적으로 참여한 참가자들의 사회인구 통계학적 특성을 분석하고 우울증 선별검사 결과를 평가하기 위하여 본 연구를 시행하였다. 방 법 : 8개 병원에서 얻어진 619명의 자료를 사용하여 선별검사로 밝혀진 우울증의 유병율과 사회인구통계학적 특성 및 응답자의 정신과적 치료를 포함한 과거력 등을 조사하였다. 결 과 : 우울증 척도 점수는 응답자 전체 평균 57.5±13.8로 경도의 우울 증상이 있는 것에 해당되었다. 전체 응답자의 69.5%(430명)가 최소한 경도 이상의 우울 증상을, 43.1%(267명)가 중등도 이상의 우울 증상을, 18.4%(114명)가 고도의 우울 증상을 보였다. 고도의 우울 증상이 있는 응답자의 56.8%와 중등도의 우울 증상이 있는 응답자의 63.9%가 정신과 치료를 받은 적이 전혀 없었다. 나이가 29세 이하인 것과 전임근무 중인 직업상태는 각각 나이가 60세 이상인 것과 직업이 없는 것에 비교하여 우울증으로부터 보호하는 인자임을 시사하였다. 결 론 : '1998 한국인 우울증 선별의 날' 행사를 통하여 많은 우울증 환자들을 선별해낼 수 있었고, 이들의 우울 증상은 몇몇 사회인구통계학적 특성과 유의한 관계가 있음을 확인하였다. 우울증 선별의 날 행사를 통한 우울증에 대한 교육과 우울증 선별검사는 치료받지 못하고 있는 우울증 환자 및 기존의 치료 중인 환자 모두에게 유용한 프로그램임을 알 수 있었다. Objectives : This study was performed to analyze the sociodemographic characteristics of participants in '1998 Korean Depression Screening Day' and to evaluate the results of the screening test. Methods : By using the survey results of 619 volunteers from 8 hospitals, the authors examined the prevalence of depression detected at the screening test and sociodemographic characteristics and the psychiatric treatment history of respondents. The assessment measure was the Zung Self-Rating Depression Scale. Results : The mean depression score of all participants was 57.5±13.8 and it came under mild depression. Of all participants, 69.5%(N=430) had at least mild depressive symptoms, 43.1%(N=267) had at least moderate symptoms, and 18.4%(N=114) had severe symptoms. Never have 56.8% of respondents in the severely depressed range and 63.9% of those in the moderately depressed range had psychiatric treatment. The results suggest that the age group of 29-year-old or younger(relative to 60-year-old or older group) and full-time employment status(relative to unemployment) are protective factors of depression. Conclusions : By '1998 Korean Depression Screening Day', many depressed patients were detected and their depressive symptoms had statistically significant relationships with some sociodemographic characteristics. The results suggest that the education and screening test programs for depressive illness facilitated by Depression Screening Day are useful to the patients regardless of being under current treatment or not.

한원정,차상윤,김은경 대한구강악안면방사선학회 2000 Imaging Science in Dentistry Vol.30 No.2

Sj□gren's syndrome is a chronic inflammatory disease that predominantly affects salivary, lacrimal and other exocrine glands. We report a case of Sj□gren's syndrome combined with MALT (mucose associated lymphoid tissue) Iymphoma which occured in the parotid gland. A 57-year-old female with the complaint of painful swelling and iymph node enlargement was referred to our department. Sialograms of both parotid glands showed globular collections of contrast material uniformly distributed throughout the parotid gland. Salivary scintigraphy showed decreased uptake of the parotid gland. CT scan showed larger, slightly more dense parotid gland than normal and honeycomb glandular appearance. Also, It showed discrete, slightly more enhanced round mass in the left parotid gland. Histopathological finding showed replacement of salivary gland parenchyma with dense small lymphocytic infiltration having the feature of epimyoepithelial islands. Kappa light chain restriction of interglandular plasma cell could be seen. (Korean J Oral maxillofac Radiol 2000; 30: 144-148)
