The spatial and temporal variations of CO2 concentrations and radiative forcing (RF) due to CO2 were examined at urban center (Yeon-dong) during 2010-2015 and background sites (Gosan) during 2010-2014 on Jeju Island. The RF at the two sites was estimated based on a simplified expression for calculating RF for the study period. Overall, annual mean CO2 concentrations at the Yeon-dong and Gosan sites have gradually increased, and the concentrations were higher at Yeon-dong (401-422 ppm) than at Gosan (398-404 ppm). The maximum CO2 concentrations at the two sites were observed in winter or spring, followed by fall and summer, with higher concentrations at Yeon-dong. The RF at Yeon-dong (annual mean of up to 0.70 W/m2 in 2015) was higher than that at Gosan (up to 0.46 W/m2 in 2014), possibly because of higher CO2 concentrations at Yeon-dong resulting from population growth and human activities (e.g., fossil fuel combustion). The highest monthly mean RFs at Yeon-dong (approximately 0.92 W/m2) and Gosan (0.52 W/m2) were observed in spring 2015 (Yeon-dong) and spring 2013 (Gosan), whereas the lowest RFs (0.17 and 0.31 W/m2, respectively) in fall 2011 (Yeon-dong) and summer in 2012 (Gosan).

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.

연구논문 : 제주지역 미세먼지의 장기변동 및 농도변화에 관한 국지기상 분석

Long-term variations of PM_{10} and the characteristics of local meteorology related to its concentration changes were analyzed at 4 air quality sites (Ido-dong, Yeon-dong, Donghong-dong, and Gosan) in Jeju during two different periods, such as PI (2001-2006) and PII (2007-2013), over a 13-year period. Overall, the long-term trend of PM_{10} was very slightly downward during the whole study period, while the high PM_{10} concentrations in PII were observed more frequently than those in PI. The concentration variations of PM_{10} during the study period was clarified in correlation between PM_{10} and meteorological variables, e.g. the low (high) PM_{10} concentration with large (small) precipitation or high (low) radiation and in part high PM_{10} concentrations (especially, Donghong-dong and Gosan) with strong wind speed and the westerly/northwesterly winds. This was likely to be caused by the transport effect (from the polluted regions of China) rather than the contribution of local emission sources. The PM_{10} concentrations in “Asian dust” and “Haze” weather types were higher, whereas those in “Precipitation”, “Fog”, and “Thunder and Lighting” weather types were lower. The contribution of long-range transport to the observed PM_{10} levels in the urban center (Ido-dong, Yeon-dong, and Donghong-dong), if estimated by comparison to the data of the background site (Gosan), was found to explain about 80% (on average) of its input.

백혈병환자의 요추천자 후 침상안정시간에 따를 두통과 요통의 차이

정영남 ( Young Nam Jeong ),이향련 ( Hyang Yeon Lee ),박영미 ( Young Mi Park ) 경희대학교 동서의학연구소 2008 동서간호학연구지 Vol.14 No.1

요추천자 후 침상안정을 취한 군(침상안정군)과 취하 지 않은 군(활동군)간의 두통의 발생 빈도를 비교하는 여러 연구가 있었으나, 어느 연구에서도 두 군간의 유 의한 차이를 발견하지 못하였다 (Carbaat & Crevel, 1981;Dieterich& Brandt 1985). 하지만 아직 대부 분의 병원에서는 요추천자 후 침상안정을 권하고 있는 실정이다 만약 요추천자 후 침상안정이 반드시 필요하지 않다면 피검자는 검사 후 일상생활에 바로 임할 수 있으므로 간호측면이나 시간적, 경제적 측면에서 많은 효과를 기대할 수 있을 것이다(KWon et al., 1997) . 실 제 서울시내 몇몇 종합병원의 경우를 보면, 성인 백혈병 환자의 요추천자가 시행된 후 대부분이 최소 6시간 이상 침상안정을 시키고 있었으며. 요추천자 후 6시간 이상 침상안정을 하는 환자들은 요통, 식사문제, 각종 검사의 지연, 생리적 현상 등을 참아 하는 고통을 갖게 된다. 특히 외래에서 요추천자를 시행한 경우에는 침상부족이라는 현실적 여건들이 6시간 침상안정을 철저히 준수하기 어렵게 한다고 사료된다. 본 연구에서 시도한 백혈병 환자의 요추천자 후 l시 간 침상안정과 6시간 침상안정에 따른 두통과 요통의 차이는 없었다. 이는 침상안정 시간이 척추마취 후 두 통 및 요통 발생에 영향을 주지 않았음을 확인한 Lee 와 mm (1996) 의 연구결과와, 소아종양환아를 대상으로 요추천자 후 1시간 및 6시간 침상안정 시간에 따라 두 통, 동반증상 및 두통의 강도는 유의한 차이가 없었다 는 Park과 Lee (1997) 의 연구결과와 유사하였다. 또한 18, 60세의 성인 신경계 환자 300명을 대상으로 전혀 침상 안정을 시키지 않은 군과 6시간 침상 안정 (3시간 은 앙와위, 3시간은 복위) 을 시킨 군의 천자 후 두통은 차이가 없음을 입증하여 침상안정을 하지 않는 것이 더 나을 것이라고 주장한 Vil血媤 등 (1988) 의 연구와 유사 하며 이는 6시간 이상 침상안정이 필요하지 않음을 시 사하고 있다. 다만 관찰할 수 있는 시간을 갖는다는 의 미에서 수평자세로 잠시 뉘어 놓는다 (Hong, 1993) 의 ‘잠지를 1시간 정도로 생각하면 무리가 없을 것으로 판단하게 된다는 근거 하에 본 연구에서 요추천자 후 l시 간 침상안정군과 6시간 침상안정군으로 구분하여 두통 정도를 비교하였을 때 두 군간에 통증 차이는 없었으며 통계적으로도 유의한 차이가 없었다 (U= 234. 0, P=. 498). 요추천자 후 요통 정도는 1시간 침상안정군과 6시간 침상안정군간에 통계적으로 유의하지 않아서 (u= 238. q p=. 532), 1시간 침상안정과 6시간 침상안정에 따른 요 통의 차이는 없는 것으로 나타났다. 이는 척추마취 환 자를 대상으로 침상안정 시간에 따른 요통의 발생률에 서 가능한 한 빨리 움직일 수 있도록 한 군이 요통 발생빈도가 적었다는 Lee와 mm (1996) 의 연구결과와 유 사하였다. 그러나 요통 점수에서 l시간 침상안정군의 평균점수보다 6시간 침상안정군의 평균점수가 높게 나 온 것은 대상자를 일찍 움직이게 하여 침상안정 시 히 리에 가해질 스트레스를 줄여 주었기 때문이 아닌가라는 견해를 피력한 Brattebo 등 (1993) 의 연구와도 관련성이 있었다. 통계적으로 유의하지 않았지만 6시간 동 안 침상안정을 시킨 군에시 요통 점수가 높은 것은 요 추천자라는 시술로 인한 스트레스 혹은 한국인에게 익숙하지 않은 침대 생활과 침대 매트리스로 얻어진 gj리 의 불펀감이 포함되었으리라 생각 되어진다. 이상으로 종합해 보면 연구대상이 백혈병으로 입원한 환자로 국한함으로써 전채 백혈병 대상자에게 연구결과를 일반화 하기는 어려우나 대상자 대부분이 움직일 수 있고 정상적인 일상생활을 할 수 있다는 점을 감안할 때 본 연구결과에서 나타난 것처럼 침상안정시간에 다른 두통과 요통정도에 차이가 없다면, l시간 이상 침상 안정을 지속하는 것이 꼭 필요한 것은 아니라고 생각된 다. 추후 연구로는 침상안정 기간 중 지속적으로 두통을 호소하는 환자에게 침상안정을 시키되 침상안정기간 동안 두통의 완화 정도 상대도 계속적으로 연구할 필요 가 있다고 사료된다. Purpose: This study was conducted for an evidence-based nursing intervention on bed rest period after puncture, by confirming whether there was a difference in scores of headache and back pain between the 1-hour bed rest group and the 6-hour bed rest group following lumbar puncture in patients with leukemia. Method: The subjects were 45 inpatients of the department of hematology at a general hospital in Seoul, from January 1 to March 31, 2005. There were 21 patients in the 1-hour bed rest group and 24 patients in the 6-hour bed rest group. A graphic rating scale was used to measure headaches and back pains. Collected data were analyzed With SPSS 12.0. Non-parametric statistics were used to analyze the data. Results: There was no significant difference between the 1-hour bed rest group and the 6-hour bed rest group in the headache level and back pain level. Conclusion: Therefore, it is considered that a long period of bed rest over 6 hours after lumbar puncture is not a necessary nursing intervention, and repeated studies are required to confirm the result.

Objective: Ultrasonographic screening between 9 and 13 weeks for fetal structural abnormalities using transvaginal sonography in unselected population. Visualization of detailed fetal anatomy in the first trimester has improved as a result of technological progress in ultrasound machines and the introduction of transvaginal sonography(TVS). Our study aims to evaluate the accuracy of TVS as a screening tool for detecting fetal malformations in a nonselected population of pregnant women. For this purpose we compared the results obtained by using second trimesster TA scanning with those obtained using TVS at 9-14 weeks' gestation. Methods: From March 2001 to February 2003, 620 unselected consecutive pregnant women were recruited at their initial visit at Soonchunhyang university hospital, department of obstetrics and gynecology and offered a TVS scan at the average gestational age of 9-13 weeks in addition to the TA screening usually performed between 22-26 weeks. To fulfill the technical requirements of a screening test, ultrasonographic examinations were performed by skillful operators with different degrees of experienced using adequate instruments Aloka SSD 5500 (Aloka Co. Ltd., Tokyo, Japan) provided with either a 3.5-5MHz TA probe or a 5-7.5MHZ TV probe) in a fixed scanning time of maximum 30 min, generally considered sufficient for a complete fetal anatomic survey. Results: During the study period we found in our unselected population an overall prevalence of target abnormalities of 2.2%(24 malformed fetuses out of 600 screened). In the fetuses examined by TVS, 16 abnormalities were detected whereas 8 were not; of these, 6 were detected at transabdominal rescreening at 22-26 weeks and the remaining 2 were observed after birth. A nuchal region abnormality was the most frequent type of malformation detected in the early scan, including six cases of nuchal edema, two cases of cystic hygroma associated with hygroma associated with hydrops, three cases of hydronephrosis, one case of fetal neck teratoma, one case of cleft lip. Conclusion: This study has demonstrated the potential of screening a low risk population for fetal abnormalities at 9-13 weeks of gestation using transvaginal sonography and rescreened via transabdominal sonography at 22-26 weeks. Larger studies are required to establish the clinical value of the first trimester scan.

The environmental impact assessment(EIA) system is used as a means to incorporate the precautionary principle, one of the basic principle of Korean environmental laws, that is to prevent pollution which may be caused by various development projects. This EIA system is worldwide conducted as enviromental policy means as well as strongly recommended to introduce it by the Rio Declaration. But each county has his own characteristic traits in practicing the EIA system according to his different legal systems and administrative culture. The most particular factor of the Korean EIA system is that similar EIA system are respectively reflected in several laws such as Act for Environmental. Impact Assessment, the Basic Envioronmental Policy Act, the national Land Use and Management Act, the Urban planning Act, etc.. The Act for Environmental Impact Assessment now limits the scope of businesses subject to EIAs, to specific development projects, but not to policy or project plans. These policy or project plans are covered by a prior consultation system differently operated from the EIA system in the Act for Environmental Impact Assessment.

The purpose of this study was to explore the effect of performance of living proprieties on family cohesion and Family satisfaction, centering on house wives in the lives of Korean housewives. The results of this study were as follows: 1. The practice of life propriety was shown to be relatively high in house wives. The variables that affected this level were as follows: perceptiveness to the importance of propriety, self-esteem, perceptiveness to resource reasonableness. 2. Family cohesion and family satisfaction revealed a relatively high level. The variables affecting the family cohesion were self-esteem, perceptiveness to resource reasonableness, age, perceptiveness to the importance of propriety. The variables affecting the family satisfaction were self-esteem, perceptiveness to resource reasonableness, perceptiveness to health, gender-role attitudes, income, perceptiveness to the standard of living, fare orientedness. 3. The degree of the practice of life propriety significantly affected family cohesion and family satisfaction. 4. On the family satisfaction, the result showed the practice of life propriety were lower figures compared to the family cohesion. The important variables affecting the Family satisfaction were self-esteem, perceptiveness to resource resaonableness, perceptiveness to the importance of propriety, degree of the practice of life propriety. In addition, it was found that the most significant variable that influenced family satisfaction was family cohesion. Future research is needed to expand its focus on the practice of life propriety in the area of family resource management. More concrete and specialized family life education programs should be developed for the benefit of building healthy families.

In order to evaluate the effect of unilateral tooth clenching, the author observed a feature of producing the symptom complex related to pain and discomfort by the isometric unilateral canine biting under force of 5㎏(FS) in Korean 31 abult females within normal masticatory function who were divided into the bilateral, the right and the left group according to their habitual sides of mastication, and analyzed the observed data statistically. The obtained results were as follows ; 1. The duration of the isometric unilateral canine biting maintained before the occurrence of symptom complex related to pain and discomfort 66.72 seconds at right side and 39.50 seconds at left side in a group of subjects with bilateral habitual mastication. And the difference of the duration between of unilateral biting side was almost significant (p<0.05). 2. The most frequent region of occurrence of symptom complex related to pain and discomfort by the isometric unilateral canine biting was the contralateral superficial masseter muscle in a group af subjects with bilateral habitual mastication.
