연구 목적 : 한국의 일 도시지역에 거주하는 청소년의 우울 증상의 유병률과 관련요인을 밝힘으로써 청소년 정신건강 증진을 위한 기초 자료를 수집하기 위하여 실시되었다. 방 법 : 연구 대상은 부천시에 거주하는 중학교나 고등학교에 재학중인 청소년 71,102명 가운데에서 무작위 집락 표본 추출법에 의해 선정된 2,203명이었으며, 이들에 대해서 CES-D(the Center for Epidemiologic Studies Depression Scale)와 사회인구학적 정보에 대한 문항이 들어 있는 설문을 실시하였다. 설문은 직접 학교를 방문하여 수행하였다. 선정된 2,203명의 청소년 가운데에 CES-D문항을 완성한 학생은 1,972명으로 반응률은 89.5%였다. 결 과 : 1) CES-D의 절단점을 16점으로 하여 계산한 '가능한' 우울 증상의 유병률은 중학생의 경우에 남학생 34.6%, 여학생 44.7%였으며, 고등학생의 경우에는 남학생 43.8%, 여학생 49.6%였다. 2) CES-D의 절단점을 25점으로 하여 계산한 '명확한' 우울증 증상의 유별률은 중학생의 경우에 남학생 18.4%, 여학생 20.7%였으며, 고등학생의 경우에는 남학생 21.4%, 여학생 23.9%였다. 3)종교, 인문계와 실업계의 여부에 따라서 우울 증상의 유병률에는 유의한 차이가 없었다. 4) 성,학년, 생활수준에 대한 자신의 평가, 가족의 구조, 성적에 대한 만족도의 다섯 가지 변수에 대해 CES-D점수가 16점 이상인 우울 증상의 유무에 따라서 로지스틱 회귀 분석을 시행하였을 때 성적에 대해 불만적 하는 군에서 매우 만족하는 군에 비해서 8.850배의 상대 위험도를 보였다. 생활 수준을 중하정도라고 대답한 군은 상이라고 대답한 군에 비해서 2.007배의 상대 위험도를 보였다. 여학생은 남학생에 비해서 1.307배의 상대 위험도를 보였다. 5) 우울 증상에 있어서 남학생과 여학생의 비율은 전체 군에서 1:1.38이며 중학생의 경우에는 1:1.88, 고등학생의 경우에는 1:1.13으로 나타났다. 고등학생에 있어 남학생의 우울 증상이 증가하는 것은 학업과 입시에 대한 부담과 관련된 것으로 생각되었다. 결 론 : 한국 일 도시거주 중고등학생에서 CES-D로 측정한 우울 증상은 남학생의 34.3%, 여학생의 47.5%에서 나타날 정도로 흔하다. 특히 학업 성적에 대해 불만족 하는 군에서 높은 우울 증상의 상대 위험률을 보이며, 고등학생에서 남학생의 우울증의 유병률이 높아지는 것은 이 지역 학생들이 학업에 대한 높은 부담을 가지고 있다는 것을 알 수 있었다. 따라서 이들에 대한 특별한 관심이 요구된다. Objective : We tried to see the prevalence and correlates of symptoms of depression in an adolescent population in Korea, and collected the basal data for mental health promotion of adolescents. Method : We sampled 2,203 adolescents among 71,102 adolescents living in Puchon City in Korea by the randomized clustered sampling method. The Center for Epidemiologic Studies Depression scale(CES-D) was used to measure depressive symptoms. The measurements were conducted through visiting schools. Of the 2,203 adolescents(aged 13 to 18) who were sampled, 1,972 persons completed CES-D and sociodemographic questions. The response rate was 89.5%. Result : 1) The prevalence rate of 'probable' depressive symptoms with cutoff point 16 was 34.3% in the boys and 47.5% in the girls. 2) The prevalence rate of 'definite' depression symptoms with cutoff point 25 was 17.4% in the boys and 20.6% in the girls. 3) We could not find any meaningful difference in the average of CES-D from the districts where they live, the course of their education, and their religions. 4) We used the logistic regression analysis to find the risk factor for adolescent depression in these samples. Among the variables degree, it was most important risk factor in adolescent depression to dissatisfy with their school degrees. Compared it with fully satisfied group, the odds ratio was 8.850. The group of mid to low socioeconomic status had the odds ratio 2.007 compared with high socioeconomic status. The girls had the odds ratio 1.307 compared with the boys. 5) The male versus female ratio was 1: 1.38 in the total students and 1 : 1.88 in the middle school students, and 1 : 1.13 in the high school students. The male versus female ratio was relatively low in the high school students. It was the result of the high prevalence of depressive symptoms in the high school boys, and it was due to the large burden to their school degrees. Conclusion : The depressive symptoms checked by CES-D were very common among adolescents in Korean urban area. The prevalence of depressive symptoms was 34.3% in the boys and 47.5% in the girls. The result that male versus female ratio was relatively low in the high school adolescents, and the group that were dissatisfied with the school degrees had high risk of depressive symptoms, revealed that the students had large burden to their school degrees and so they needed special concerns.

For more effective intraperitoneal chemotherapy, the authers made 5-fluorouracil-polyglycolic acid composite disks(FU-PGA disks) with 5-fluorouracil and polyglycolic acid, a biodegradable polymer. We inserted the FU-PGA disk into the peritoneal cavites of Sprague-Dawley male rats, the control and three experimental groups; one FU-PGA disk insert group(300mg/kg), two FU-PGA disk insert group(600mg/kg), and three FU-PGA disk insert group(900mg/kg). The control group received a similar number of PGA disk inserts. A pharmacokinetic study was performed to measure the 5-fluorouracil concentration in the peritoneal fluid, blood, and tissues(liver, kidney and heart) at 24 hours, 72hours and 168 hours after insertion of the FU-PGA disk. Light and electron microscopic studies were done. The results were as follows: 1) The number of white blood cells and platelets decreased after FU-PGA insertion. The degree was proportional to the duration and amounts inserted. The change in the number of red blood cells varied slightly. 2) Light microscopically, slight changes were noted at 168 hours in the 3 disk insert group (900mg/kg). Mild fatty change and hepatocyte degeneration around the central veins of the liver were noted, with vacuolar degeneration in the proximal convoluted tubules of the kidney. 3) Electron microscopically,the liver showed focal increases of lipid droplets in the hepatocytes, and irregular nuclear membrane with focal nucleolar segregation of the fibrillar and granular elements. Also the double membranous structure of the hepatocytes and Kupffer cells was widened with bleb formation. The kidney showed wide separation of the nuclear double membrane in the proximal convoluted tubular cells and mesangial cells, with vacuolation and myelin figure formation in the mitochondria of the proximal convoluted tubular cells, at 72 hours and 168 hours in the 2 to 3 FU-PGA insert groups. The heart showed focal loss of cristae,vacuolation and myelin figure formation in the mitochondria of the 2 to 3 FU-PGA insert groups. In conclusion, despite the large amont of FU-PGA inserted, the histopathological changes in the liver, kidney and heart were slight, and consonant with the very low amount of 5-fluorouracil concentrations detected in the liver, kidney and heart. The above results suggest that the FU-PGA composite can serve as a new device for releasing drugs in a controlled manner and easily targeted to intraperitoneal organs. This device can improve the efficacy of intraperitoneal chemotherapy for gastric cancer.

Engineering of AlON interlayer in Al₂O₃/AlON/In_0.53Ga_0.47As gate stacks by thermal atomic layer deposition

Lee, Woo Chul,Cho, Cheol Jin,Park, Suk-In,Jun, Dong-Hwan,Song, Jin Dong,Hwang, Cheol Seong,Kim, Seong Keun ELSEVIER 2018 CURRENT APPLIED PHYSICS Vol.18 No.8

<P>The presence of an AlN interfacial layer in high-k/In0.53Ga0.47As gate stacks improves the interfacial properties and enhances the electrical performance of devices. However, pure AlN is rarely grown by atomic layer deposition (ALD) because of the low reactivity of NH3 toward the common Al-precursor and the predisposition to oxidation of the grown AlN layer. Although a plasma-enhanced ALD technique significantly suppresses the oxygen content in the grown AlN layer, the deterioration of the interface properties by plasma-damage is a critical issue. In this work, an AlON interlayer was engineered by optimizing the NH3 feeding time in thermal ALD to improve the interface quality in Al2O3/AlON/In0.53Ga0.47As capacitors. It was determined that a mere increase in the NH3 feeding time during the ALD of the AlON film resulted in a higher nitrogen incorporation into the AlON interlayer, leading to a reduction in the interface trap density. Furthermore, the out-diffusion of elements from the In0.53Ga0.47As layer was effectively suppressed by increasing the NH3 feeding time. This work demonstrates that simple process optimization can improve the interface quality in high-k/In0.53Ga0.47As gate stacks without the use of any plasma-activated nitrogen source.</P>

GLUTARALDEHYDE 처리한 가견 절단 치수조직의 중장기간 관찰

조규증,박진훈,신홍인 慶北大學校 齒科大學 1988 慶北齒大論文集 Vol.5 No.1

성견의 상하악치아 총 84개을 대상으로 생활치수절단술을 시행한후, 2% 및 4% GA희석액을 실험군으로, Dycal을 대조군으로 적용하여 4개월 경과후 그치수반응을 광학현미경으로 관찰한 바 다음과 같은 결과를 얻었다. Dycal군을 제외한 전 실험군 표본은 치수 전방에 걸친 광범위한 염증세포의 침윤을 나타내었으며 그 정도는 미만성에 미세 농양 형성까지 다양하였고 GA 2%군에서 보다는 GA 4%군에서 더 심한 양상이었다. 2차 상아질의 형성은 치수벽 전면에 걸쳐 각 실험군 모든 표본에서 현저하여 치수강이 상당히 협소화되어졌으며 그 정도는 Dycal군에서 가장 왕성하였고 다음은 GA 2%군, 4%군 순이었다. 특히 Dyucal군에서는 2차 상아질에의한 상아교의 형성이 명확했다. This experimental study was performed to evaluate the pulpal response to the glutaraldehyde diluted to 2% and 4%, comparing with the response to the Dycal as control group, in 84 teeth of dogs with routine vital puloptomy. The animals were sacrificed after 4 months following pulpotomy and each specimen was prepared for histopathologic examination with light microscope. The results were as follows; The specimen of experimental groups, 2% glutaraldehyde dressing group and 4% glutaraldehyde dressing group, showed diffuse inflammatory infiltrate with or without microabscess formation in all experimental periods. In general the inflammatory infiltrate was severer in 4% glutaraldehyde dressing group than in 2%. On the contrary, the control group, Dycal dressing group, showed no inflammatory infiltrate in all specimens. The reparative dentin formation along dentinal walls resulting in narrowing of pulpal cavity was marked in all experimental and control groups. The peripheral deposition of calcified tissue was most favorable in Dycal dressing group and was followed in descending order of 2% and 4% dressing groups. The dentin bridge was not formed except for Dycal group showing complete formation.

조병채,김인규,변진석,백봉수 大韓成形外科學會 1991 Archives of Plastic Surgery Vol.18 No.1

This study was conducted to clarify the inhibitory effect of flurbiprofen, prednisolone, and gabexate mesilate on the synthesis of prostaglandin F2a and thromboxane B2 in the tissue of electrical burn. one hundred sixty Sprague-Dawley rats, 250gm of body weight in average, were divided into 4 groups of control, flurbiprofen, prednisolone and gabexate mesilate administred group. Fourty rats of the each group were subdivided into 1st, 2nd, 4th, 7th postburn day with 10 rats in each subgroup. Ten rats were used for normal values of prostaglandin F2a and thromboxane B2. Flurbiprodfen 30mg/kg was given per mouth, and prednisolone acetate 5mg/kg and gabaxate mesilate 50mg/kg were administred intramuscularly 5 minutes after burn injury and then once a day. All but bone tissue of within 2cm area of the current entry were harvested and ground into homogenate. The levels of prostaglandin F2a and thromoboxane B2 were measured by Radioimmunoassay. The results were as followings: In normal rat tissue, the level of prostagland F2a and thromboxane B2 were 15.8±1.8 and 17.6±2.8ng/mg protein in each. In the control group the levels of both prostaglandin F2a and thromboxane B2 increased abruptly to 5 times and 7 thimes in the first day and maintained the same level in the second day. After then they rapidly decreased and returned to a near normal level in the fourth day. The increase of thromboxane B2 was more remarkable than that of prostaglandin F2a. In the flurbiprofen group, the level of thromboxane B2 was not inerease but kept at a normal level. The average level of prostaglandin F2a in the post-burn first and second day was 59.5% lower than of the control group. The average level on the post-burn first and second day was 61% lower in thromboxane B2 and 33% lower in prostaglandin F2a in the prednisolone group, and 68% lower in throboxane B2 and 48% lower in prostaglandin F2a in the gabexate mesilate group, compared to the control group. These findings suggest that electrically injured tissue is vigrously progressive due to rapid increase of thromboxane B2 and prostaglandin F2a, as inflammatory mediators, in the post-burn first and second day, is nonprogressive after the post-burn fourth day. The flurbiprodfen was the most effective of the three drugs(flurbiprofen, gabexate mesilate, prednisolone in order of effectiveness) to suppress the synthesis of thromboxane B2 prostaglandin F2a of the electrieally injured tissue.

Feasibility and Effects of a Postoperative Recovery Exercise Program Developed Specifically for Gastric Cancer Patients (PREP-GC) Undergoing Minimally Invasive Gastrectomy

Cho, In,Son, Younsun,Song, Sejong,Bae, Yoon Jung,Kim, Youn Nam,Kim, Hyoung-Il,Lee, Dae Taek,Hyung, Woo Jin The Korean Gastric Cancer Association 2018 Journal of gastric cancer Vol.18 No.2

Purpose: Exercise intervention after surgery has been found to improve physical fitness and quality of life (QOL). The purpose of this study was to investigate the feasibility and effects of a postoperative recovery exercise program developed specifically for gastric cancer patients (PREP-GC) undergoing minimally invasive gastrectomy. Materials and Methods: Twenty-four patients treated surgically for early gastric cancer were enrolled in the PREP-GC. The exercise program comprised sessions of In-hospital Exercise (1 week), Home Exercise (1 week), and Fitness Improvement Exercise (8 weeks). Adherence and compliance to PREP-GC were evaluated. In addition, body composition, physical fitness, and QOL were assessed during the preoperative period, after the postoperative recovery (2 weeks after surgery), and upon completing the PREP-GC (10 weeks after surgery). Results: Of the 24 enrolled patients, 20 completed the study without any adverse events related to the PREP-GC. Adherence and compliance rates to the Fitness Improvement Exercise were 79.4% and 99.4%, respectively. Upon completing the PREP-GC, patients also exhibited restored cardiopulmonary function and muscular strength, with improved muscular endurance and flexibility (P<0.05). Compared to those in the preoperative period, no differences were found in symptom scale scores measured using the European Organization for Research and Treatment of Cancer (EORTC) Core Quality of Life Questionnaire (QLQ-C30) and Quality of Life Questionnaire-Stomach Cancer-Specific Module (QLQ-STO22); however, higher scores for global health status and emotional functioning were observed after completing the PREP-GC (P<0.05). Conclusions: In gastric cancer patients undergoing minimally invasive gastrectomy, PREP-GC was found to be feasible and safe, with high adherence and compliance. Although randomized studies evaluating the benefits of exercise intervention during postoperative recovery are needed, surgeons should encourage patients to participate in systematic exercise intervention programs in the early postoperative period (Registered at the ClinicalTrials.gov, NCT01751880).

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.

Fosfomycin, a low molecular antibiotic, is to be easily synthesized, therefore to be possibly used in veterinary sectors due to econimic reasons. In this study, we determined the antibacterial activities of fosfomycin against some domestic animal-origin pathogens, and its combined effects with some important antibacterials available. We also compared detection methods of fosfomycin from various measuring instruments. The results obtained through this experiment were as follows: 1. Antibacterial activities of fosfomycin against the pathogens used in this experiment were appeared fairly low. We found the antobacterial activities depanded on the kinds of media and the addition of some material thereins, which suggests the importance of appropriate medium so as to judge the antibacterial activity of fosfomycin. 2. Fosfomycin showed varying antibacterial effects in combination with other antibacterials, which should be taken into consideration when combining other antobacterials especially in the clinical settings. Of the combined antivacterials, fosfomycin had synergistic effects in combination with amoxicillin but antagonistic effects with oxytetracyline. 3. Conventional detection methods using HPLC, GC and spectrophotometer were not appropriate to measure fosfomycin. Capillary electrophoresis by the way of the indirect ultraviolet detection method was good enough to detect fosfomycin in the range of expected concentration in tissues, with the limit of quantitation (LOQ) of 1.25 ㎍/㎖. We recommend the eletrophoresis method could be used to detect fosfomycin, thereby being able to set the optimal dosage for animals and providing the measures in relation with the residual concentration in the meat.

We need the constitute of Emergency medical system that connect prehospital care of inhospital care effectively for optimal treatment of emergency patient. The analysis of actual condition of our emergency medical system, through study of mortality case in emergency medical center will be a aid to the constitute. The authors performed a review on the records of 60 cases who died in Ajou university Emergency medical center during management, since June 1994 to september 1995. Among the 60 patient, 72% were male and 28% were female. In nontrauma patient, 6th decade was many, in trauma patients, 3rd and 5th decade was many. Among the 60 patient, 33% were traumatic cases, 66% were nontraumatic cases. Among the traumatic patients, more than half of the cases were due to motor vehicle accidents. The most frequent time interval from onset of emergent situation to arreving at emergency center was more than 2 hours. The most common transfer method was by 119 ambulance. In most cases, prehospital treatments were not taken. In most cases, initial mental status was comatose, and systolic blood pressure was less than 60 mmHg. Most cardiovascular resuscitation was done in 30 min. to an hour. In cases as traffic accident of ischemic heart disease, where rapid transportation of the patient is critical for the patient's survival, however, in most cases it took more than two hours to bring such patients to hospital, and first aid treatment before arrival to hospital was rare. No prehospital treatment was done to nearly all patient. In many cases the patient was already in under coma or shock state. The inhospital care at emergency center was made relatively quickly and adequately. The mean duration of cardiopulmonary resustation was 30min to one hour. From this study, we could notice the poor quality of prehospital care in the region ,near Ajou university hospital, and we came to know that the improvement of quality of prehospital care was the most important factor to reduce the motality of emergency department patient. that is, in the treatment of emergency patients, weak points has been revealed in the pre-hospital treatment, the improvement of which is important factor for the survival of emergency patients.
