양철주 順天大學校 1997 論文集 Vol.16 No.1

본 연구는 건설현장에서 발생한 소음이 인근 양돈농장에서 사육중인 돼지들에게 유·사산, 폐사, 성장지연 등의 생리적 영향과 그 여파로 인한 경영상의 손실액을 객관적으로 평가하기 위하여 수행되었으며, 그 결과를 다음과 같이 요약하였다. 1. 양돈의 유·사산, 폐사, 성장지연을 초래할 가능성이 있는 각종 요인들을 분석한 결과 가장 주된 환경요인은 소음에 의한 영향이었으며, 이러한 소음에 의한 환경스트레스는 돼지의 내분비 균형에 영향을 미쳐서 유·사산 및 번식장해를 일으키는데 직접적인 원인이 되었다. 2. 소음으로 인해서 172두중 54두가 유·사산 (31%)되었고, 모돈 78두중 9두가 불임돈(12%), 모돈 1두가 폐사 (1.3%)되었으며, 전체적인 성장지연은 8.9%로 나타났다. 3. 가족의 정신적인 피해 등을 제외한 순수한 양돈경영의 손실은 전국 평균가격들을 적용한 결과 공사피해일 35일 (94. 7. 20 ∼ 94. 8. 23)을 기준으로 총 6,789,342원으로 평가되었다. 본 연구의 결과는 양돈업에 대한 소음피해가 발생시 고려해야 할 보상항목 및 산정방법론을 제시함으로 산업화 과정에서 빈번하게 발생할 수 있는 유사한 경우에 피해농가에 대한 공정한 보상의 기회를 제공하는 근거를 확보하는 효과를 얻음과 동시에 보상액 산정과정에서 발생할 수 있는 소모적인 의견대립문제를 해소함으로서 공익성이 큰 건설사업의 집행를 농가와 함께 보호하는 효과를 얻었다. This study was carried out to evaluate the physiological effects of noise on a pig breeding farm resulting in abortion, stillbirth, death and delay of growth in pigs. Therefore, we conducted tests to estimate economic losses resulting from the sound stress of a construction site near a pig farming facility. The results were as follows: 1. Following the evaluation of environmental noise pollution and its effects on a pig farming facility, it was found that noise was directly linked to an unbalancing of the endocrine glands in pigs. This unbalancing led to an increase in abortion, stillbirth, death and failure to reproduce offspring. 2. The following results of environmental noise pollution are: 31% (54/172) of new born pigs, abortions and stillbirth; 12%(9/78) of sows, unfertilized pigs; 1.3% (1/78) of sows, death. Total delay of growth was 8.9% of pig population in the pig breeding farm. 3. Exempting environmental noise pollution effects on human mental stability; net income loss for this pig farming facility due to environmental noise pollution was estimated to total 6,789,342 won after being adjusted to the average national price of pork over 35 working day ('97. 7. 20 ∼ '97. 8. 23). This study has provided an argument for compensation to farmers from construction firms, and has provided calculation methods in estimating environmental noise pollution on pig breeding farms.

김철재,박현신,배현주,이지해,양일선,강혜승 한국식생활문화학회 2002 韓國食生活文化學會誌 Vol.17 No.3

The purpose of this study was to analyze the problems arising from the actual conditions of the Foodbank, and to implement the HACCP system as a solution in terms of increasing the safety of donated food within the Foodbank. In order to apply HACCP system, the entire Foodbank working process such as preparation, collection, transportation, division, and distribution was considered and analyzed to decide the application point for CCPs. Donated foods mainly consisted of processed foods, raw materials, lunch boxes, and cooked foods from mass catering establishments, which dominated over the others in terms of quantity. Cooked foods were divided into three groups based on menu-types and processing methods. Temperature, pH, and aw were measured on cooked foods, and Total Plate Count, Coliforms, E. coli, Salmonella spp., Staphylococcus aureus, Listeria monocytogenes, and E. coli O157:H7 were conducted in order to apply a HACCP plan. Form these experiments, temperature, pH, and aw of donated food were likely contributed to microbial growth. Donated foods before HACCP implementation showed high numbers in terms of total plate count and Coliforms, both well over the acceptable standard levels. By setting the CCPs on maintenance of donated food below 10℃ and using a 75 ℃ reheating method, microbiological hazard levels were able to be controlled and lowered. From these results, it is concluded that in order to guarantee food safety, foods donated to the Foodbank must not only maintain a reasonable level of initial microbiological growth, but also must be handled properly through time and temperature controls within the Foodbank system. Furthermore, in terms of implementing the HACCP plan within the Foodbank management structure, basic food safety and sanitation measures, such as reheating facilities and various cold chain systmes such as refrigerated vehicle for food transportation are importantly needed. The training and education of Foodbank personnel and management in areas such as awareness of hygiene and safe food handling and practice are also required and necessary.

Background and Objectives : Interstitial cells of Cajal(ICC) are the pacemakers in gastrointestinal tract that modulates gastrointestinal motiliey and these cells also transmit neural input from enteric nerves to smooth muscles. Recent work on tissues from patients with motility disorders that suggest that loss or defect in ICC could be related to pathophysiology in human and animal models. Immunolabelling of ICC in intestinal wall is recently developed by using specific marker, anti-c-kit antibody. Immunohistochemistry was done for ICC network in attempt to provide a morphological basis for the mechanism regulating gastrointestinal motility Methods : Cryosection was done, and whole-mount preparations of mouse stomach, gastrointestinal tract were immunolabelled using the anti-c-Kit. Immunolabelled ICC networks were observed under a confocal laser scanning microscopy. Results : According to three dimensional reconstruction study, we found that the c-Kit-positive celluar networks were widely distributed in the gastrointestinal muscle (1) circular muscle layer(IC-IM), (2) myenteric plexus(IC-MY), (3) deep muscular plexus(IC-DMP) in ileum, (4) submucosal plexus(IC-SMP) and longitudinal muscle layer(IC-LM) in colon. Conclusion : The characteristic profiles of ICC celluar networks provide a morphological basis upon the mechanism regulating gastrointestinal motility. Additional studies for the enteric nerves-ICC interaction are need to evaluate the detailed roles of Icc in gastrointestinal tract.

Objectives : The purpose of this study was to investigate the stress coping strategies and psychological charactehstics, such as combined psychopathology and tendency of symptom interpretation, in patients with somatization disorder. Methods : Thirty patients meeting the criteria of DSM-IV somatization disorder were compared with thirty controls. We evaluated the subjects using Symptom Checklist-90-Revised (SCL-90-R), Somato-Sensory Amplification Scale (SSAS), Symptom Interpretation Questionnaire (SIQ), and The Ways of Stress Coping Questionnaire (SCQ). Independent t-test and Pearson correlation analysis were used. Results : From the results of SCL-90-R subscales, the scores of somatization, obsession-compulsion, depression, anxiety, and psychoticism were significantly higher in patients with somatization disorder than nonnal controls. Somatization disorder patients had greater amplification of physical sensation in SSAS and significantly higher score in physical interpretation of SIQ compared with psychological or environmental interpretation, In the SCQ of somatization disorder patients, we observed generallylower levels of total coping scores than the control group and significant positive correlation between passive coping style of SCQ and psychological interpretation of SIQ. Conclusion : These results show that patients with somatization disorder have various psychopathology, greater amplification of physical sensation, physical interpretation tendency of symptoms, and insufficient copying strategy.

이창섭,박성주,이용철,이양근,이흥범 대한감염학회 2010 감염과 화학요법 Vol.42 No.3

Vancomycin-resistant enterococci (VRE) infection is a serious problem because optimal therapy has not been established. Different agents in various combinations, including teicoplanin, chloramphenicol, and quinupristin/dalfopristin, have been used to treat patients with VRE meningitis, but the efficacy of these agents is not satisfactory because of their limited ability to penetrate into the cerebrospinal fluid. We report a case of nosocomial vancomycin-resistant Enterococcus faecium meningitis in a patient with ventriculoperitoneal shunt that was successfully treated with linezolid. We will also review previously reported cases of vancomycinresistant E. faecium meningitis treated by linezolid.

목적 : 2002년 말 중국에서 SARS가 발생한 이후 국내에서도 2003년 10월까지 총 3명의 추정환자, 17명의 의심환자가 보고되었다. 향후 추가적인 SARS의 유행이 우려되는 상황에서, 그간의 SARS 환자 진료에 있어서의 실질적인 준비사항, 진료 현황 등에 대한 조사를 통해 문제점을 파악하여, 향후 더 나은 대비가 될 수 있도록 개선점을 제시하고자 하였다. 재료 및 방법 : SARS로 의심되는 환자를 진료 경험이 있는 병원의료진을 대상으로 2003년 10월에 설문조사를 실시하였다. 설문에는 SARS 환자 진료 시의 실질적인 조치, 진료 현황, 병실, 응급실 및 외래에서의 격리 시설과 준비사항, 보건당국의 관리와 지원에 관한 사항을 포함하였다. 결과 : 대상이 되는 22개 병원 중 17개(17/22, 77.2%) 병원이 설문에 응하였다. SARS 환자를 위한 격리실은 응급실, 외래, 일반병실 및 중환자실에서 각각 9개(9/17, 52.9%), 5개(5/17, 29.4%), 15개(15/16, 93.7%), 4개(4/16, 25%) 병원에서 음압처리가 되어있지 않은 일인실 혹은 다인실이 사용되었고, 1개(1/16, 6.3%) 병원에서만 일반병실에서 음압격리실이 운영되었다. 입원환자의 진찰 시 개인보호구의 착용은 거의 모든 의료기관에서 이루어졌다. 보건당국에서 SARS지정병원의 시설 등을 사전에 확인한 곳은 1곳(1/12, 8.3%)이였고, 14개 병원(14/15, 93.3%)에서는 보건당국에 의뢰한 검사결과를 통하 받지 못하였다. 결론 : 의료기관에서 SARS 환자용 격리실뿐만 아니라 기존의 격리실 설비 등이 미흡하였으며, 특히 중환자실 및 외래의 준비가 더욱 부족하였다. 보건당국의 의료기관에 대한 종합적인 지원이 부족하였고, 병원과의 원활한 연계가 잘 이루어지지 않았다. SARS 만이 아닌 격리를 필요로 하는 질환의 적절한 진료를 위해 향후 병원 시설의 정비와 정부차원에서의 보다 구체적이고 실질적인 대책마련이 필요하다. Background : There was an worldwide outbreak of the Severe Acute Respiratory Syndrome (SARS) originated from China in late 2002. During that period three cases of suspected SARS and 17 cases of probable SARS were reported in Korea. With the concerns about the reemergence of SARS-coV transmission, it is important to be prepared for any possibility. So, this study is aimed to analysis the past measures in managing SARS and propose the amendatory plans to improve the preparedness. Materials & Methods : Questionnaires were collected among clinicians with any experience in managing the probable or suspected SARS cases in Oct. 2003. 17 out of 22 hospitals responded to the questionnaire. The contents in the questionnaire were practical activities, personal equipments, response plans, isolation facilities in emergency centers, outpatient clinics, general wards and intensive care units, and relationship with the public health department. Results : The dedicated isolation rooms in emergency centers, outpatient clinics, general wards, and intensive care units were prepared in 9 (9/17, 52.9%), 5 (5/17, 29.4%), 15 (15/16, 93.7%), and 4 (4/16, 25.0%) hospitals, respectively. Except for one hospital that newly made negative pressure room for SARS, single or multi-bed rooms without airborne infection control were used in all the other hospitals. The personal precaution principles were kept quite well in general wards. Before the designation of SARS hospital by the public health department prior evalution to see if the hospital was suitable for managing SARS was conducted in only 1 (1/12, 8.3%) hospital. The results of laboratory diagnosis were reported back in 1 (1/15, 6.6%) hospital. Conclusions : The isolation facilities which can control airborne infection were almost deficient not only for SARS but also for other respiratory transmissible diseases. For the infection control of transmissible diseases including SARS, more investment is needed on medical facilities and comprehensive support from the public health department required.

<P><B>Abstract</B></P> <P>The thermochemical properties of uranium compounds have attracted much interest in relation to thermochemical treatments and the safe disposal of radioactive waste bearing uranium compounds. The characteristics of the thermal decomposition of uranium metaphosphate, U(PO<SUB>3</SUB>)<SUB>4</SUB>, into uranium pyrophosphate, UP<SUB>2</SUB>O<SUB>7</SUB>, have been studied from the view point of reaction kinetics and acting mechanisms. A mixture of U(PO<SUB>3</SUB>)<SUB>4</SUB> and UP<SUB>2</SUB>O<SUB>7</SUB> was prepared from the pyrolysis residue of uranium-bearing spent TBP. A kinetic analysis of the reaction of U(PO<SUB>3</SUB>)<SUB>4</SUB> into UP<SUB>2</SUB>O<SUB>7</SUB> was conducted using an isoconversional method and a master plot method on the basis of data from a non-isothermal thermogravimetric analysis. The thermal decomposition of U(PO<SUB>3</SUB>)<SUB>4</SUB> into UP<SUB>2</SUB>O<SUB>7</SUB> followed a single-step reaction with an activation energy of 175.29 ± 1.58 kJ mol<SUP>−1</SUP>. The most probable kinetic model was determined as a type of nucleation and nuclei-growth models, the Avrami-Erofeev model (A3), which describes that there are certain restrictions on nuclei growth of UP<SUB>2</SUB>O<SUB>7</SUB> during the solid-state decomposition of U(PO<SUB>3</SUB>)<SUB>4</SUB>.</P> <P><B>Highlights</B></P> <P> <UL> <LI> Thermal decomposition kinetics of U(PO<SUB>3</SUB>)<SUB>4</SUB> into UP<SUB>2</SUB>O<SUB>7</SUB> was investigated. </LI> <LI> The thermal decomposition followed a single-step reaction with an activation energy of 175.3 ± 1.6 kJ mol<SUP>−1</SUP>. </LI> <LI> The most probable kinetic model was determined as a type of nucleation and nuclei-growth models, the Avrami-Erofeev (A3). </LI> </UL> </P>

목 적: 국소적으로 진행된, 절제 불가능한 췌장암 치료에 있어 고식적 방사선 치료와 비교하여 CyberKnife (CK)를 이용한 정위 방사선 치료의 생존율 및 급성 독성에 대해 분석하고자 하였다. 대상 및 방법: 2003년 4월부터 2004년 4월까지의, Eastern Cooperative Oncology Group (ECOG) 활동도 3 이하이며 CT 및 PET/CT로 평가하여 원격 전이 없는 국소 진행된 췌장암 환자 19명을 대상으로 하였다. 대상 환자는 점차 방사선량을 증가시키는 방법으로 33 Gy, 36 Gy, 39 Gy를 3분할로 각각 6명, 4명, 9명에서 CK를 이용한 정위 방사선 치료를 시행하였으며, 생존율 및 Radiation Therapeutic Oncology Group (RTOG) acute radiation morbidity criteria에 의한 위장관 독성을 분석하였다. 또한 나이, 성별, ECOG 수행 점수, 항암 치료,우회로 조성술(bypass surgery) 여부, 방사선량, CA19-9, 계획용 표적 체적(planning target volume, PTV), CT상 주위 장기 및 혈관 침범 여부 등을 Log Rank test를 이용하여 예후 인자를 평가하였다.결 과: 본 연구에서 중앙 생존 기간은 11개월, 1년 생존율은 36.8%였다. 추적 조사 기간 중(범위 3∼20개월, 중앙값 10개월) 유의한 위장관 급성 독성은 관찰되지 않았다. 단일 인자 분석에서 계획용 표적 체적만이 유의한 예후 인자로 80 cc 이하인 경우가 80 cc 이상인 경우보다 생존율이 높았으며(p-value<0.05), 나이, 성별, ECOG 수행 점수, 항암 치료, 우회로 조성술, CA19-9 수치, 주위 장기 및 혈관 침범 여부 등에서는 통계적으로 유의한 차이를 보이지 않았다. 다인자 분석에서는 65세 이하인 경우와 PTV 80 cc 이하인 경우에서 생존율이 높았다. 결 론: 고식적 방사선 치료, 고선량 입체조형 방사선 치료(high dose conformal radiation therapy), 수술 중 방사선 치료(intraoperative radiation therapy) 또는 세기 조절 방사선 치료(intensity modulated radiation therapy, IMRT)를 이용한 최근의 결과와 비교하여 CK를 이용한 정위 방사선 치료는 생존율 측면에서 비슷하거나 나은 결과를 보였다. 또한 심각한 부작용은 관찰되지 않았으며 짧은 기간의 치료로 환자에게 편의를 제공할수 있어 결과적으로 삶의 질을 향상시킬 수 있을 것이다. 따라서, 이 새로운 치료 방법은 국소 진행된, 절제불가능한 췌장암 환자에서 심각한 부작용 없는 효과적인 치료가 될 것으로 생각된다. 또한 계획용 표적 체적은 CK 치료의 유용한 예후 인자로 사용될 것이다. Purpose: In order to find out whether stereotactic radiation therapy (RT) using CyberKnife (CK) could improve survival rate and lower acute toxicity compared to conventional RT. Materials and Methods: From April 2003 through April 2004, 19 patients with Eastern Cooperative Oncology Group (ECOG) performance status ≤3 and locally advanced pancreas cancer without distant metastasis, evaluated by CT or PET/CT, were included. We administered stereotactic RT consisting of either 33 Gy, 36 Gy or 39 Gy in 3 fractions to 6, 4 and 9 patients, respectively, in an effort to increase the radiation dose step by step, and analyzed the survival rate and gastrointestinal toxicities by the acute radiation morbidity criteria of Radiation Therapeutic Oncology Group (RTOG). Prognostic factors of age, sex, ECOG performance score, chemotherapy, bypass surgery, radiation dose, CA19-9, planning target volume (PTV), and adjacent organ and vessel invasion on CT scan were evaluated by Log Rank test. Results: The median survival time was 11 months with 1-year survival rate of 36.8%. During follow-up period (range 3∼20 months, median 10 months), no significant gastrointestinal acute toxicity (RTOG grade 3) was observed. In univariate analysis, age, sex, ECOG performance score, chemotherapy, bypass surgery, radiation dose, CA19-9 level, and adjacent organ and vessel invasion did not show any significant changes of survival rate, however, patients with PTV (80 cc showed more favorable survival rate than those with PTV>80 cc (p-value<0.05). In multivariate analysis, age younger than 65 years and PTV>80 cc showed better survival rate. Conclusion: In terms of survival, the efficacy of stereotactic radiation therapy using CK was found to be superior or similar to other recent studies achieved with conventional RT with intensive chemotherapy, high dose conformal RT, intraoperative RT (IORT), or intensity modulated RT (IMRT). Furthermore, severe toxicity was not observed. Short treatment time in relation to the short life expectancy gave patients more convenience and, finally, quality of life would be increased. Consequently, this could be regarded as an effective novel treatment modality for locally advanced, unresectable pancreas cancer. PTV would be a helpful prognostic factor for CK.
