Conflicting results exist on the outcome of off hours PCI in ST elevation myocardial infarction (STEMI). However, there were only a few studies that have focused on the clinical characteristics and outcomes of off hours PCI in STEMI. So, we studied the clinical characteristics and hospital mortality in STEMI patients treated with primary PCI during regular hours (weekdays 9:00 AM to 6:00 PM) versus off hours Weekdays 6:01 PM to 8:59 AM, weekends, and holidays) in Korea Acute Myocardial Infarction Registry. We analyzed in hospital and one year mortality among 5,665 consecutive ST segment elevation myocardial infarction patients treated with primary PCI between November 2005 to January 2008. Total 2,848 (50.2%) patients were treated during off hours. Baseline finding were similar, although regular hours patients were older. Median symptom to balloon time (304 min, IQR 175 to 750 vs. 270 min, IQR 145 to 551, p=0.001) were longer for regular hours primary PCI. Median door to balloon time (71min, IQR: 48 to 132 vs. 59 min, IQR 39 to 110 min, p=0.001) were longer for off hours pPCI. Also, Cardiac enzyme such as Max CK-MB (212.1±299.3 vs 194.7±303.4, p=0.031) and max TnI (72.6±239.5 vs. 58.9±94.4, p=0.013) were increased in off hours pPCI. However, unadjusted in hospital (6.0% off hours vs. 6.0% regular hours, p=0.946) and one year cardiac mortality (11.3% off hours vs. 11.7% regular hours, p=0.661) were comparable. In multivariate analysis, off hours primary PCI did not predict an adverse outcome. In conclusion, when primary PCI was performed within an appropriate reperfusion strategy, the clinical effectiveness of either off hours or regular hours pPCI is comparable.

Bone graft has been used to repair one defect caused by disease and trauma, congenital and acquired deformities. Graft materials are autogenous bone, allogenic bone, xenogenic bone, synthetics. Autogenous bone graft is the most superior to other materials for immunologic reaction, compatibility to host tissue, and revascularization. However, autogenous bone graft is required for additional operation and the amount of taking is limited. Autografts are obtained at own expense and also limited in size, shape. In order to compensate these problems, allogenic bone graft has been used increasingly. But allogenic bone graft encounters immunologic complications. Therefore, it has been used after freezing, lyophilization, or demineralization. Allogenic bone processed by only lyophilization includes potential antigenic properties on its surface, therefore it is demineralized to deplete immunologic reaction. Demineralized bone releases BMP and helps the mesenchymal cells transform to the chondroblast to produce cartilage and bone. This reaction is called osteoinducation. Many authors have reported that mineralized lyophilized bone had less antigenicity clinically and favorable bony consideration with host bone. In our department from 1995 to now, we have used banked allogenic bone graft that has been prepared from Wonkwang Bone Bank in 5 cases and mineralized lyophilized bone graft in 2 cases to reconstruct the maxillofacial bone defect after tumor resection and cyst enucleation and cleft alveolus. We will report with literature review that the result is favorable functionally and esthetically.

최근 들어 도심지 재개발과 산업단지 조성 등이 활발하게 진행되면서 깎기 비탈면의 효율적 활용과 민원방지 그리고 환경훼손을 최소화할 수 있는 공법의 필요성이 점차 커지고 있다. 판넬식 옹벽은 지보재 보강을 통해 원지반의 전단강도를 증가시키고 전면판인 프리캐스트 판넬과 지보재를 체결하여 개별적 벽체를 형성시킴으로써 수평토압에 저항하는 공법이다. 프리캐스트판넬의 적용으로 기존 옹벽에서 발생하던 콘크리트 현장타설에 의한 공기지연과 콘크리트 품질저하 등의 문제는 다소 해결되었지만 비탈면 과다절취에 의한 사토처리 및 토취장 확보, 및 옹벽 전면 콘크리트 노출로 인한 경관성 저하문제는 여전히 미결과제로 남아있는 실정이다. 본 연구에서는 기존 판넬식옹벽의 단점을 보완하기 위하여 판넬 전면을 자연암반형으로 연출하고 수직의 원지반에도 부착이 가능하도록 공정을 개선하였으며 실내 및 현장시험을 통하여 개발된 옹벽의 현장 적용성 평가를 수행하였다. 판넬에 대한 실내시험을 수행하여 자연암반형 판넬의 자체강도 및 거동특성에 대한 검증을 수행하였으며 현장 시험시공을 통하여 수직절취 및 원지반 부착에 대한 현장 적용성을 평가하였다. 또한 시험시공 시 보강재 및 비탈면에 대한 계측을 수행하였으며 이를 3차원 수치해석 결과와 비교·분석하였다. 실내시험 결과 사보강에 의한 판넬의 펀칭강도 증가를 확인하였으며 현장 시험시공을 통하여 원지반 부착식 옹벽의 시공성 및 현장 적용성을 확인하였다. 또한, 장기계측 및 수치해석적검증을 통하여 원지반 부착식 옹벽 시스템이 시공중 및 장기적으로 안정성이 확보됨을 확인하였다. New building methods are needed to aid increased inner-city redevelopment and industrial construction. A particular area of improvement is the efficient use of cut slopes, with the minimization of associated problems. A retaining wall of precast panels can resist the horizontal earth pressure by increasing the shear strength of the ground and reinforcing it through contact with the panels. Precast panels allow quick construction and avoid the problem of concrete deterioration. Other problems to be solved include the digging of borrow pits, the disposal of material cut from the slope, and degradation of the landscape caused by the exposed concrete retaining wall.This study suggest the methods of improvement of an existing precast panel wall system by changing the appearance of the panels to that of natural rock and improving the process of adhering the panel to a vertical slope. The panels were tested in the laboratory and in the field. The laboratory test verified their specific strength and behavior, and the field test assessed the panels`` ground adherence at a vertical cutting. Reinforcement of the cutting slope was also measured and compared with the results of 3D numerical analysis. The results of laboratory test, identified that the shear bar increase the punching resistance of panel. And as a results of test construction, identified the construct ability and field applicability of the panel wall system adhered to in-situ ground. In addition to that, extended measurement and numerical analysis, identified the long-term stability of panel wall system adhered to in-situ ground.

Validation of Sea Surface Temperature (SST) from Satellite Passive Microwave Sensor (GPM/GMI) and Causes of SST Errors in the Northwest Pacific

Passive microwave sea surface temperatures (SST) were validated in the Northwest Pacific using a total of 102,294 collocated matchup data between Global Precipitation Measurement (GPM) / GPM Microwave Sensor(GMI) data and oceanic in-situ temperature measurements from March 2014 to December 2016. A root-mean-square (RMS) error and a bias error of the GMI SST measurements were evaluated to $0.93^{\circ}C$ and $0.05^{\circ}C$, respectively. The SST differences between GMI and in-situ measurements were caused by various factors such as wind speed, columnar atmospheric water vapor, land contamination near coastline or islands. The GMI SSTs were found to be higher than the in-situ temperature measurements at low wind speed (<6 m/s) during the daytime. As the wind speed increased at night, SST errors showed positive bias. In addition, other factors, coming from atmospheric water vapor, sensitivity degradation at a low temperature range, and land contamination, also contributed to the errors. One of remarkable characteristics of the errors was their latitudinal dependence with large errors at high latitudes above $30^{\circ}N$. Seasonal characteristics revealed that the errors were most frequently observed in winter with a significant positive deviation. This implies that SST errors tend to be large under conditions of high wind speeds and low SSTs. Understanding of microwave SST errors in this study is anticipated to compensate less temporal capability of Infrared SSTs and to contribute to increase a satellite observation rate with time, especially in SST composite process.

Bone resorption is accomplished by the removal of both mineral and the organic matrix. The cellular origin of bone collagenase that is responsible for the removal of unmineralized organic matrix has remained equivocal. This study was performed to investigate the effect of PTH on the release of collagenase and cellular origin of bone collagenase in bone cell populations. Calvaria from fetal rat at 19-day of gestation, were sequentially digested by the enzyme solution consisted of collagenase, trypsin and EDTA for 10 min (PopulationI), 10 min (II), 10 min (III), 20 min (IV) and 20 min (V). Each bone cell population was primarily cultured for 6-7 days and splited to 5.0×10^5 cells/35mm culture dish and then incubated for 6 days with MEM with or without PTH (1.0U/ml). Collected medium was incubated with type I collagen for 6h at 37℃ and then used for hydroxyproline determination by Woessner's method. The results were as follows. 1. There were no significant differences of collagenase activity among 5 bone cell populations. 2. PTH (1.0U/ml) had no effect on the collagenase activity in the population I, II, III and V. 3. PTH (1.0U/ml) significantly increased collagenase activity in population IV.

정신과에 대한 의대생들의 태도를 조사하기 위해서 정신과 임상실습을 마친 S대학교 의과대학 본과 4학년 학생들 중에서 본 연구의 설문조사에 자원응답한 70명의 자료를 분석하였다. 의대생들의 56%는 정신과가 비과학적이고 애매한 학문이라는 견해를 부정하였다. 또한 90%는 환자의 감정적 문제를 다룰 필요가 있다고 보았다. 타과의사들과 수입을 비교할 때 반수정도가 보통이라고 하였다. 83%의 의대생들은 정신과에 매력을 느끼고, 69%는 지적 성취를 할 수 있다고 보았다. 그러나, 정신과 의사의 역할과 임상심리학자나 사회사업가의 역할을 구분하는데 혼동이 있었다. 결과는 대부분의 의대생들이 정신과 의사와 직업으로서의 정신과에 대해 긍적적인 태도를 가진 것으로 나타났다. The attitudes of medical students towards psychiatry are important as they influence recruitment to psychiatry and clinical practice. In order to evaluate the attitudes of medical students towards psychiatry, the authors administered a questionnaire to 70 senior student volunteers of College of Medicine, Seoul National University. The results are summarized as follows; Psychiatrists are .not regarded by most medical students as unclear thinkers. Medical students don't think that psychiatrists abuse patients' legal rights, treat only relatively healthy patients. Most medical students affirm the importance of dealing with their patients' emotional problems. But, the roles of psychiatrists are confused with those of psychologists and social workers. Psychiatry, as a vocation, is not regarded by most medical students as unscientific, imprecise, ineffective and low in status. Most medical students don't agree that stigmatization or pressure to choose another field are common. This study showed that most senior medical students are favorable about psychiatrists and psychiatry.
