To investigate the effect of alcohol drinking on the absence pattern, we conducted survey for 606 male workers who employed at the small & medium sized manufacturing factories located in Taejon city and Chungnam region. The following results were obtained. Among the variables, age, marrital status, body mass index, smoking, working hours per day, and working climate showed significant realtionship with the alcohol drinking times. Gross absence days and sickness absence days showed significant relation with alcohol drinking frequency, but non-sickness absence days did not showed any relation with alcohol drinking frequency. After adjusting the variables which had significnat relation with absence days and alcohol drinking, there were still significant relation between absence days and alcohol drinking frequency.

연구목적: 정신분열병 환자에서의 재활치료는 개인의 극복 기술과 능력을 향상시키고 재발을 유발시킬 수 있는 스트레스의 부정적인 영향을 중화시킴으로써 질병의 만성화를 막고 사회기능을 호전시킬 수 있기에 점차 그 중요성이 대두되고 있다. 본 연구는 만성 정신분열병 입원 환자에서 재활치료의 하나인 단축형 증상관리 훈련이 정신장애에 대한 자기 인식에 미치는 효능을 알아보기 위하여 시행되었다. 방법: 정신분열병으로 진단받고 입원 중인 환자들에게 재발경고징후를 규명하는 것, 재발경고징후를 관리하는 것, 지속증상을 극복하는 것, 술과 불법 약물을 피하는 것 등으로 구성된 승인-UCLA 사회기술 및 독립적인 생활기술훈련 단위 중 증상관리단위를 기초로 한국실정에 맞게 축약한 증산관리 훈련을 주 1회, 60분씩, 4∼5주간 실시하였고 실시 전후에 전신장애 비인식 평가 척도(Scale to Assess Unawareness ofMental Disorder; 이하 SUMD)로 자신의 정신장애에 대한 인식을 평가하였으며 임상적 전반적 인상(Clinical Global Impression;이하 CGI)로 임상 상태를 조사하였고 각 인구학적 변인들을 조사하였다. 결과: 환자 30명이 훈련을 완수하였으며 이들의 평균 연령은 36.6±7.6세였고 남자가 14명(46.7%), 여자가16명(53.3%)이었다. SUMD 점수는 훈련 전 16.9±4.0점에서 훈련 후 12.9±4.2점으로 유의하게 줄어 정신장애에 대한 자기 인식 정도가 향상되었으며(p<0.01), CGI도 훈련전의 3.7±0.9점에서 훈련 후 2.8±0.8점으로 유의하게 호전되었다(p<0.01). 환자의 연령, 발병시 연령, 유병 기간, 입원 기간, 항정신병약물 사용 용량, 교육 정도, CGI로 평가한 임상 상태등은 정신장애의 자기 인식 정도와는 관련성이 없었다. 결론: 정신분열병 입원 환자에서 단축형 증상관리 훈련은 정신장애에 대한 자기 인식을 증가시킬 수 있는 방법이 될 가능성을 확인하였으며 이 방법이 정신분열병 재활치료의 중요한 요소가 될 수 있음을 알 수 있었다. Objectives : The purpose of this study was to examine whether Symptom Management Module-Korean Brief Version(SMM-B) is effective as a psychosocial treatment of the inpat-ients with chronic schizophrenia. We also questioned which of demographic and clinical characteristics could be predictors of differential treatment response. Methods : The subjects were composed of 30 inpatients with chronic schizophrenia, who were trained with weekly session of SMM-B for 5 weeks. Before and after the training, the level of psychopathology, knowledge about schizophrenia were assessed as dependent variables by using Clinical Global Impression(CGI) and Scale to Assess Unawareness of Mental Disorder(SUMD). Results : Overall, patients showed improvement over the treatment period on psychopath-ology as well as knowledge about psychosis. Total scores of SUMD were changed from 16.9±4.0 before training to 12.9±4.2 after training(p<0.01) and scores of CGI were improved from 3.7±0.9 to 2.8±0.8<p<0.01). Howver age, gender, years of education, age of onset, duration of illness, duration of admission, numbers of psychiatric admission, and clinical status evaluated by CGI were not correlated with unawareness of psychosis. Conclusion : These results suggest that SMM-B could be a reliable method to improve self-aw-areness of psychosis in patients whth chronic schizophrenia and one of important elements in rehabilitation.

After the vehicle has become a large formation with high-speed, loud noise from an express highway is increasing, and the number of large-scale apartment complexes, which are recently being constructed in the metropolitan area nearby the express highway and IC, is increasing gradually. Compared with a main road, the traffic volume and the speed of a vehicle between IC and the ramp way [turn-off] are smaller. If the ramp way is rightly connected with the downtown area, however, the traffic-noise that comes about in surrounding areas will be in conjunction with the traffic-noise from the main road of express highway and that of the ramp way. This research has selected a place that hasn't had a road or a commercial quarter nearby the main-road of IC and ramp way. Then we have studied the traffic-noise status under minimizing influence of its outer-noise, which occurs in IC. 1. The traffic volume change of a small and full-sized car with time has been kept on regularity in 2004 and 2005. As the traffic volume of a full-sized car has diminished remarkably, it has been maintaining through 6:00a.m.-10:00 a.m. As it has decreased since lO:OO a.m.. we have also observed the traffic proportion going up. 2. Monthly traffic volume of small cars was higher in May, August and October than other months. We have observed that the high traffic volume during these months is due to the following: May-The Damyang festival, August-a high-demand season, October-viewing scarlet maple leaves. Monthly traffic volume of full-sized cars was generally higher in August, but it has decreased during 2006. This was due to the many construction trucks that were working on the extension of the 88 Olympic expressway. Therefore, there was more traffic volume in 2006 compared to 2004 and 2005. 3. In this study, the noise figures have been less than 55 dB(A) in 18 spots. There were 14 spots from 55dB(A) to 58dB(A). 58-61dB(A) : 20, 61-64dB(A) : 17, 64-67dB(A) : 18. There were 8 spots we observed at the highest level from 67dB(A) to 70dB(A). Those were the nearby spots separating the main road and Damyang IC. 4. Traffic-noise at the boundary between IC and the main road of an expressway was higher than that of the same distance in other places. 5. We have observed that traffic-noise is low in places with mountains that serve the role of soundproofing walls. Thus, the fundamental sound hadn't affected it.

권성일,박기룡,김현영,신채희,임영찬,최영식,박요한,이강대,장희경,이재화,염하용 대한내분비학회 2002 Endocrinology and metabolism Vol.17 No.4

연구배경: 갑상선암은 다른 조직에 발생한 암에 비해 비교적 천천히 자라므로 대부분 예후가 양호하지만, 일부에서는 주위 조직으로 침윤하거나 혹은 원격 전이로 인하여 치명적인 결과를 초래할 수 있다. 갑상선전절제술 및 131^I 제거술 후 경과 관찰시 갑상선암의 재발과 전이의 진단에 있어 131^I 스캔과 혈청 Tg의 측정이 현재 임상에서 가장 많이 이용되고 있으나 이 방법에는 여러 가지의 결점이 있다. 최근 Tg mRNA에 대한 RT-PCR법을 이용한 여러 연구결과는 131^I 스캔과 혈청 Tg 측정의 결점을 보완할 수 있는 좋은 보조적인 진단법으로 이용할 수 있을 가능성을 제시하였다. 이에 말초혈액에서 측정한 Tg mRNA에 대한 RT-PCR법이 갑상선 절제술 및 방사성요드 치료 후 갑상선암의 재발 및 전이 유무의 진단에 유용한가를 알아보고자 이 연구 시행하였다. 방법: 분화된 갑상선암으로 진단된 후 갑상선전절제술을 시행받고 방사성요드 치료를 받은 환자 중 현재까지 한차례에 이상 추적 방사성요드 전신 스캔을 시행하고 추적관찰이 가능했던 유두선암 35예, 여포선암 5예를 대상으로 연구를 시행하였다. 대상군은 131^I 스캔 소견상 음성인 군(Group Ⅰ), 잔여조직이 있는 군(Group Ⅱ), 국소전이가 있는 군(Group Ⅲ), 및 원격전이 군(Group Ⅳ)으로 구분하였다. 정상 대조군은 갑상선질환이 없는 10예의 건강인으로 하였다. 대상환자의 말초혈액을 이용한 Tg mRNA에 대해 특이적인 primer를 이용하여 RT-PCR 및 nested RT-PCR을 시행하였다. 결과: 본 연구 결과는 다음과 같다. 1) 131^I 스캔 소견상 음성인 군 21예 중 1예에서 Tg가 양성소견을 보였다. Anti Tg Ab가 양성인 4예 모두 Tg가 음성을 보였다. 잔여조직이 있거나 국소전이 및 원격전이를 보인 군 19예 중 Tg가 양성인 경우는 4예였으나, Tg mRNA는 전예에서 양성이었다. 2) 131^I 스캔에서 국소 및 원격전이 소견을 보인 8예 중 4예에서 Tg가 음성으로 131^I 스캔과 혈청 Tg 사이에 불일치 소견을 보였다. 3) 말초혈액에서 특이적인 primer를 이용하여 RT-PCR 및 nested RT-PCR을 시행한 결과 대상군 40예 및 정상 대조군 10예 모두에서 Tg mRNA가 양성을 보였다. 결론: 본 연구에서 갑상선 절제술 및 방사성요드 치료 후 갑상선암의 재발 및 전이 유무를 평가함에 있어 역전사 중합효소 연쇄 반응법을 이용한 Tg mRNA 측정의 의의는 재평가되어야 한다고 생각된다. Background: Differentiated thyroid cancer is the most common endocrine malignancy. Despite advances in the treatment of thyroid cancer, disease recurrence and metastasis may occur in as many as 20% of patients, and so continues to pose major problems in its clinical management. Serum thyroglobulin (Tg) measurements, by immunoassay, are used to detect residual or recurrent thyroid cancer following thyriod ablation. However, the usefulness of immunoassay is limited by both the requirement for thyroid hormone withdrawal, to attain optimal test sensitivity, and interference by the antithyroglobulin antibody (Anti-Tg Ab). Recent studies have reported the clinical usefulness of reverse transcription-polymerase chain reaction (RT-PCR) detection of Tg mRNA in the peripheral blood of patients with differentiated thyroid carcinomas. We performed this study to evaluated the usefulness RT-PCR of Tg mRNA in peripheral blood of patients with thyroid carcinoma following a total thyroidectomy and radioiodine ablation therapy. Methods: Forty cases that underwent a total thyroidectomy and radioiodine ablation therapy were included in this study. Of the 40 patients, 35 were papillary carcinomas and 5 were follicular carcinomas. Ten normal control subjects were also studied. Tg mRNA was extracted. Then RT-PCR and nested RT-PCR, were run with specific Tg primers. Concurrently, DNA sequencing of the isolates was carried out to prove the isolates were identical to the nucleotide sequence of the Tg. Results: The Tg was detected in 4 of 19 patients, with either a residual thyroid bed, or metastasis, on a 131^I whole body scan and in 1 of 21 patients with a negative radioiodine scan. Surprisingly, the Tg mRNA was detected in all the patients and normal controls. Conclusion: From our results we can not recommend Tg mRNA, detected by RT-PCR in peripheral blood, as a tumor marker superior to that of the Tg serum level. We consider an intensive re-evaluation of the method is required before considering its clinical applications (J Kor Soc Endocrinol 17:501∼513, 2002).

Because mountain streams have narrow widths and steep slopes compared to streams and lakes, hours of immobility are considerably short, and the quality of mountain streams has been greatly influenced by rainfall, land-use, components of the streambed and types of forests. During the summer when heavy rainfall occurs, eroded earth and sand flow into mountain streams and cause temporarily high turbidity. It is also the cause of eutrophication, which is frequently found in downstream. As evaluation standards for the quality of mountain streams were not established in Korea, this quality was evaluated by examining some items based on quality standards for drinkable water and research on the influences of pollution in mountain streams, which showed that these were seldom in downstream water systems. Mountain streams within Wolchulsan National Park flow into a reservoir and when characteristics of mountain streams from forests and rainfall that flow into mountain streams through forest ecosystems were studied, results of measuring its changes are as follows. Monthly changes of pH were low between April and August and higher starting October, and the EC was measured higher in the winter and the spring and tended to be low starting April. The EC on the 19th of May and the 23rd of October and the concentration of floating materials and COD_(Mn) were observed to be higher due to the influence of rainfall on the 19th of May and the 22nd of October, and it was judged that the washing out of dried deposits attached to the water pipe and the leaching of woods were influenced by rainfall. It is considered that real-time monitoring of water quality for a long time and water quality conditions during and after rainfall should be examined for ensuring basic data of water quality and evaluating characteristics and seasonableness of mountain streams, which may be greatly changed by artificial influence in the future.

Chae, Yong Hwa,Kwak, Dong Wook,Kim, Moon Young,Park, So Yeon,Lee, Bom Yi,Lee, Yeon Woo,Lee, Young Ho,Song, Mi Jin,Ryu, Hyun Mee Korean Society of Medical Genetics and Genomics 2013 대한의학유전학회지 Vol.10 No.2

Purpose: This study was designed to determine the frequency and echocardiographic findings of 22q11.2 deletions in fetuses with cardiac defects on fetal ultrasound or familial backgrounds of 22q11.2 deletions. Materials and methods: We retrospectively reviewed the medical and ultrasonographic records of 170 fetuses that underwent fluorescence in situ hybridization (FISH) analysis for chromosome 22q11.2 deletions between February 2001 and April 2013. Results: Among 145 fetuses with cardiac defects, six (4.1%) had 22q11.2 deletions. Deletions of 22q11.2 were detected in 6 (5%) of the 120 fetuses with conotruncal defects: 5 (8.9%) of 56 with tetralogy of Fallot (TOF) and 1 (5.9%) of 17 with double outlet right ventricle (DORV). No deletions were found in cases of pulmonary atresia, truncus arteriosus, right aortic arch, or transposition of the great arteries. No 22q11.2 deletions were found in non-conotruncal cardiac malformations. Among 25 fetuses with familial backgrounds of 22q11.2 deletions, one (4%) had a maternally inherited 22q11.2 deletion with no cardiac findings. Conclusion: Knowledge of the frequency and echocardiographic findings of 22q11.2 deletions might be helpful for prenatal genetic counseling. It is advisable to perform FISH analysis for 22q11.2 deletions in pregnancies exhibiting conotruncal cardiac defects such as TOF or DORV.
