Health Risk Appraisal(HRA) is usually defined as a process by which we expect of individual's chances of death or acquiring specific diseases within a defined period of time. The concept of worksite as an area of health maintenance and promotion is newly developing. Our movement for health promotion of employees has been increasingly known in the worksite. The aim of this study is to develop health risk appraisal tools about health promotion at the worksite for employees. We performed this study by two steps; one step was to develop a HRA questionnaire of worksites in Korea, another was to evaluate the reliability of the questionnaire. For developing HRA questionnaire, we reviewed scientific examples at first, and then weighted the score by delphi. To evaluate the reliability of developed questionnaire, we carried out survey by test-retest method. A total of 131 employees completed HRA questionnaire on two times. The results are as follows. The total score of health risk in unhealthy workers was higher than that of healthy workers. The range of test-retest reliability of responses to the questionnaire was 0.57-0.94. Therefore it seems that this questionnaire was very suitable to assess the health behavior of workers. In conclusion, the developed HRA questionnaire can be used as a tool for evaluating health behavior and for providing health counseling materials.

Acinetobacter species is a non-fermentative aerobic gram-negative coccobacillus that is an important pathogen found in nosocomial infections. Recently, multi-drug resistant Acinetobacter baumannii (MDR-AB) infections have been increasing and pose a serious problem. Most such infections present as bacteremia, pneumonia, or a wound infection; however, CNS infections are very rare. We herein present a case of ventriculitis caused by MDR-AB in a 37-year old man after a neurosurgical intervention. The patient was successfully treated with intrathecal colistimethate.

무증상으로 발견된 담낭-담관 누공을 동반한 Mirizzi 증후군 1예

홍진희,전태주,서지영,서동대,오태훈,신원창,최원충,신은아,김기환 인제대학교 2009 仁濟醫學 Vol.30 No.-

Mirizzi's syndrome is a rare complication of the gallstone disease, characterized by narrowing of the common bile duct (CBD) due to chronic extrinsic compression of an impacted gallstone in the cystic duct or the neck of the gallbladder. The impacted gallstone may erode into the bile duct, causing cholecystocholedochal fistula. The patients generally have history of repeated attacks of jaundice and abdominal pain. But there is no report about asymptomatic Mirizzi syndrome with cholecystocholedochal fistula which were found incidentally. So herein we present our clinical experience with a case of asymptomatic Mirizzi syndrome with cholecystocholedochal fistula in a young female.

저자들은 정신분열병의 일부에서는 태생기 동안 유전 외적인 환경적 요인이 크게 작용할 것이라는 가정 하에 형제 정신분열병 환자군(남 15. 여 7)과 산발성 정신분열병 환자군(남 16, 여 7) 및 정상 대조군(남 16, 여 7)을 대상으로 가족력에 따른 산과적 합병증과 신체 미세 기형을 비교하였다. 산과적 합병증은 Lewis 척도를 이용하여 연구 대상의 어머니와 면담하여 평가하였고 신체미세기형은 Waldrop 척도를 이용하여 측정하였다. 또한 산과적 합병증 및 신체 미세기형과 가족력에에 따라 발병 연령 등의 임상 양상들이 차이를 보이는지 비교함으로써 정신분열병을 좀 더 동질적인 아형으로 나눌 수 있는지를 검토하였다. 1) 형제 환자군, 산발성 환자군 및 정상 대조군의 세균에서 산과적 합병증의 개개의 항목 및 전체 점수의 유의한 차이는 없었다. 신체 미세기형의 경우 입의 미세기 형에서 유의한 차이가 있었으나 그 외에 각 부위별 점수 및 전체 점수에서는 세 군간에 유의한 차이가 없었다. 그러나 대부분의 신체 미세기형 세부 항목 및 전체점수에서 산발성 환자군이 형제 환자군에 비해 높은 신체 미세기형의 점수를 보이는 경향이 있었다. 2) 산과적 합병증의 전체 점수와 신체 미세기형의 전체 점수 사이에 상호 연관성을 찾아볼 수 없었다. 3) 발병연령·정신병리·약물에 대한 반응·병전 기능수준·지연성 운동장애 유무 등의 임상 양상들을 비교하였을때 산발성 환자군과 형제 환자군간에 유의한 차이가 없었다. 4) 산과적 합병증 및 신체 미세기형과 임상 양상들을 비교하였을 때, 형제 환자군에서 분만시간과 회복시 전반적 기능수준간에, 산발성 환자군에서 산과적 합병증의 전체 점수와 발병 연령간에 상관관계가 있었으나 전체적으로 일관된 결과가 도출되지는 못하였다. 위와 같은 결과를 종합하여 볼 때, 산과적 합병증이나 신체 미세기형이 정신분열병의 원인을 밝히는데 유익한 도구가 될 수는 있지만, 가족력 유무에 따라 정신분열병을 보다 동질적인 아형으로 구분하기 힘들다고 생각되었다. In order to test the hypothesis that familial schizophrenics have fewer chances of receiving organic insults during the fetal neural development than sporadic schizophrenics, the authors compared obstetric complications, minor physical anomalies, and other clinical features in sibling schizophrenics, sporadic schizophrenics and controls. Obstetric complications were evaluated by the scale of Lewis, and minor physical anomalies were measured by the Waldrop scale. Sporadic schizophrenics had a significantly higher Waldrop score for mouth than sibling schizophrenics. Although there was some tendency of higher total scores for minor physical anomalies in sporadic schizophrenics, there were no statistically significant differences in obstetric complications and the other minor physical anomalies among three groups. There was no significant correlation between obstetric complications and minor physical anomalies. The clinical features such as age of onset, psychopathology, response to drugs, premorbid functioning, and tardive dyskinesia were not significantly different between sibling and sporadic scizophrenics. In conclusion, while the obstetric complications and minor physical anomalies were suggested to be useful in the search for the cause of schizophrenia, it was difficult to categorize schizophrenics into more homogeneous groups according to family history of schizophrenia using the parameter of obstetric complications and/ or minor physical anomalies.

Objectives : To evaluate the absorbed and effective doses of spiral and computed tomography for the dental implant planning. Materials and Methods : For radiographic projection, TLD chips were placed in 22 sites of humanoid phantom to record the exposure to skin and the mean absorbed dose to bone marrow, thyroid, pituitary, parotid and submandibular glands and nesophagus. Effective dose was calculated, using the method suggested by Frederiksen et al.. Patient situations of a single tooth gap in upper and lower midline region, edentulous maxilla and mandible were simulated for spiral tomography.35 axial slices(maxilla) and 40 axial slices (mandible) with low and standard dose setting were used for computed tomography. All the radiographic procedures were repeated three times. Results : The mean effective dose in case of maxilla was 0.865 mSv,0.452 mSv,0.136 mSv and 0.025 mSv, in spiral tomography of complete edentulous maxilla, computed tomography with standard mAs , computed nomography with low mAs and spiral tomography of a single tooth gap (p〈0.05). That in case of mandible was 0.614 mSv, 0.448 mSv, 0.137 mSv and 0.036 mSv, in spiral tomography of complete edentulous mandible, computed tomography with standard mAs, computed tomography with low mAs and spiral tomography of a single tooth gap (p〈0.05). Conclusions : Based on these results, it can be concluded that low mAs computed tomography is recommended instead of spiral tomography for the complete edentulous maxilla and mandible dental implant treatment planning.

홍창희,장은진 부산대학교 심리과학연구소 2001 심리과학연구 Vol.2 No.-

이 연구의 목적은 만성 정신분열병 환자들의 학습잠재력에 따른 인지재활훈련의 효과를 살펴보는 것이다. 만성 정신분열병으로 진단된 환자들을 위스콘신 카드분류 검사를 사용하여 학습잠재력이 높은 집단과 낮은 집단으로 나누고 각 집단에서 5명씩을 선별하여 인지재활훈련을 실시하였다. 인지재활훈련은 1회기에 60분, 일 주일에 3회기 총 12회기가 실시되었고 훈련 전, 직후, 훈련종료 한 달 후 훈련 참가자들의 주의력, 기억력, 개념형성 및 유지능력을 측정하였다. 측정시기별 환자 개인의 변화를 살펴본 결과, 측정 시기에 걸쳐 변화가 없는 환자를 제외한다면, 학습잠재력이 높은 집단의 환자들 모두 훈련 전에 비해 훈련 직후 주의력, 기억력, 개념형성 및 유지 능력이 향상되었다. 이 중 주의력, 개념형성 및 유지능력은 향상된 기능이 훈련종료 한 달 후까지 유지되고 있었다. 학습잠재력이 낮은 집단의 환자들은 주의력과 기억력에서 훈련 직후 향상을 나타내었으나 향상된 기능이 훈련종료 한 달 후까지 유지되는데는 집단 내 환자들 간에 서로 차이가 많았다. 학습잠재력이 높은 집단에 비해 낮은 집단에서 각 인지 기능에서 측정 시기에 걸쳐 변화가 없는 환자의 수가 더 많았고, 훈련 직후 각 인지 기능의 향상 정도는 학습잠재력이 높은 집단이 낮은 집단보다 더 컸다. 이 연구의 함의와 제한점을 논의하였다. The purpose of this study was to examine the effects of cognitive rehabilitation training according to the learning potential of chronic schizophrenics. The chronic schizophrenics were administered Wisconsin Card Sorting Test twice. They were divided into high learning potential group and low learning potential group based on the changes in the first and second performance outcome. Four patients from high learning potential group and four patients from low group participated in cognitive rehabilitation training of 12 sessions, three times a week Each session lasted for 60 minutes. The cognitive rehabilitation training was consisted of attention training, memory training, and concept formation training. Attention(sustained attention, vigilance, digit span), memory(verbal memory, visual memory), and concept formation were assessed before, after and a month later the training. The results of statistical analysis revealed that the effects of cognitive rehabilitation training were different according to the learning potential in sustained attention, verbal memory, and concept formation. After training, in sustained attention, high learning potential group showed significant improvement, but low group didn't. The difference lasted for a month. In verbal memory, both groups showed significant improvement. However, high learning potential group improved more than low group, and the difference lasted for a month. In concept formation, after training, both groups showed no significant improvement. A month later the training, however, both groups had a difference in changes of concept formation. The high learning potential group showed significant improvement in concept formation, but the low group didn't. Here's the meaning of this study. First, in an effort to maximize the effects of the cognitive rehabilitation training, this study showed that it's necessary to make up groups with the same level of learning potential. Second, it showed that each patient, who participates in the cognitive rehabilitation training, needs a different rehabilitation method. And it showed more concrete ways to rehabilitate patients. Third, it showed ways to raise the cost-efficiency of the therapy and increased the possibility of rehabilitation for chronic schizophrenics.
