Today, satellite remote sensing (RS) and geographic information systems (GIS) plays an important role as an advanced science and technology. This study was developed a Line Density Algorithm which was clarify and describe the thermal front by using NOAA SST (sea surface temperature) and GIS spatial analysis for systemic and effective management of fish raising industry and sea environmental pollution by land reclamation program. Before this, a study about a interpolation method was carry out which was very important for estimate the hidden value between a special point. For this study Inverse Distance Weighted interpolation, Spline interpolation, Kriging interpolation methods were choose and SST data from 2001 to 2004 in spring (March, April, May) were analyzed. According to the study Kriging interpolation method was the very adaptive method from a practical point of view and excellent in description and precision then others. Finally, the result of this study will be use for develope the Line Density Index Algorism.

Congenital long-segment tracheal stenosis which involves nearly entire trachea and carina is very rare disease, but leads to life threatening obstruction in infancy and childhood. Symptoms are ranged from stridor and wheezing to severe cyanosis and respiratory failure. Routine chest X-ray is somewhat helpful to diagnose it, but definitive diagnosis can be made by bronchoscopy or tracheogram for severely narrowed tracheal lumen.Recently, we experienced a case of congenital tracheal stenois, type 1 by Cantrell classification with carinal involvement. After costal cartilage was designed as oval shaped flap and covered with pericardium, anterior and posterior augmentation was done with prepared costal cartilage.This patient died of respiratory failure at 13 days postoperatively, probably due to sustaining obstruction in association in with failure to make a sufficient widening at carinal level.Important issues in the management of congenital tracheal stenosis are rapid diagnosis, selection of appropriate surgical procedure, and detailed anesthetic schedule.In the future, more biocompatible material and more effective surgical procedures should be studied to reduce the surgical mortality and morbidity of the complicated tracheal stenosis.

Background and Objectives Dizziness is not uncommon in children. The etiology of dizzinessvaries according to different studies due to different methods of examination or characteristicsof the dizziness center. To assess meaningful causes of dizziness in children, a multidisciplinaryapproach would be needed. The purpose of this study was to analyze the mainpathologies associated with vertigo and dizziness in children, paying particular attention torecent diagnostic advances with a multidisciplinary approach. Subjects and Method A total of 73 children, aged between 4-18 years, who visited thePediatric Dizziness Clinic of the University Hospital from January 2016 to June 2016 were includedin this study. Medical records were reviewed retrospectively. All of the subjects wereexamined by history, questionnaires, physical examinations, electrocardiogram, hematologictests, brain MRI scan, audiogram and vestibular function tests. Patients who had orthostaticsymptoms additionally underwent a tilt table test, and in selective cases, a caloric and vestibularevoked myogenic potential tests as well. Results Vestibular migraine (VM) and benign paroxysmal vertigo of childhood (BPVC)were found in 35.6% and 27.4% of the children with dizziness, respectively. The incidence oforthostatic hypotension and postural orthostatic tachycardia syndrome were 12.3% each, bothof which are higher than other previous reports. Other causes were Meniere’s disease, benignparoxysmal positional vertigo, vestibular neuritis and so on. Conclusion VM and BPVC were the most common causes of pediatric dizziness. Also, theincidence of orthostatic dizziness was rather high in pediatric population. The evaluation of dizzinessin children should include a thorough check of history (questionnaire), neurotologicalexamination, vestibular function tests and a tilt table test.

This is a case report of a 57-year-old patient diagnosed with bradycardia and atrioventricular (AV) block. The chief complaint of the patient was palpitation and dizziness. An electrocardiogram (ECG) showed a second degree AV block with 2:1 AV conduction. The patient was treated with Korean medicine, including herbal medicine, for 35 days. After 2 weeks of treatment, the heart rate increased from 33 to 56 and the follow-up electrocardiogram showed normal findings. The symptoms of palpitation and dizziness were also improved. The effect on heart rate, ECG, and symptoms lasted until the end of the treatment. This case report demonstrated that Korean medicine could be effective for treatment of symptomatic bradycardia with AV block.

협력치안서비스의 공공성 확보를 위한 정책적 함의: 민간경비를 중심으로

이형민,이민형 대한정치학회 2014 大韓政治學會報 Vol.22 No.2

민간경비가 과연 시장경제의 원리에 따른 사적 자치영역에서의 계약적 서비스 관점에서만 바라봐야 하는지에 대한 의문이 제기되며, 그러한 문제제기의 이면에는 ‘경비’가 지니고 있는 안전의 문제를 논함에 있어서 민간영역에서 수요와 공급의 경제원칙으로 해결할 수 없는 공공성을 무시할 수 없다는 점에 초점이 맞춰진다. 민간경비의 공공성에 따라 범죄예방이라는 공익을 추구하기 위해서는 그 역할 확대가 필연적이며, 이를 위한 공신력 확보 방안이 강구되어야 한다. 즉 경찰에 버금가는 치안서비스의 공동생산자로서 협력치안의 한축을 담당하게 될 민간경비의 서비스 품질이 시민들의 수요를 충족시킬 만큼 향상되어야 하며, 이를 자율적으로 이행하기 위한 제도적 개선책이 마련되어야 한다. 이를 위해서는 경비업체에 대한 인증제와 그 구성원들에 대한 자격제도가 시행되어야 하며, 이를 위한 경영평가가 선행되어 정부 지원의 정당성을 확보하여야 한다. 시장원리에 따른 단가 조정과 이에 따른 인건비 축소는 양질의 경비서비스를 제공하는데 걸림돌이 되고 있으므로, 이를 해결하기 위한 정부의 지원이 절실히 요구된다.

Ingestion of plant material rarely manifest in clinical intoxication. This is due to the relatively low toxicity of most plants in Korea. But, veratrum is an important plant on account of its highly toxic alkaloids. Five cases of Veratrum grandiflonum mass poisoning are described. Clinical symptoms occurred quickly, within 30 min. Vomiting, a fall in blood pressure and bradycardia was observed. Treatments in the emergency department included gastric lavage, activated charcoal, and administration of atropine and dopamine for bradycardia and hypotension. Although one of them experienced profound hypotension, bradycardia and mental change, the outcomes were favorable in all cases, producing a complete cure without any sequellae at discharge.

We evaluated sixteen patients of traumatic diaphragmatic injuries that we have experienced from Jan. 1987 to Aug 1993. Age was ranged from 6 to 71 years, predominantly in the fourth and fifth decades. 13 were male and 3 were female, a ratio of 4.3: 1. Blunt trauma was develped in 11 [Lt 7, Rt 4], penetrating trauma in 5 [Lt 2, Rt 3]. Preoperative diagnosis of diaphragmatic injury was possible in 8 patients [72.2 %] in blunt trauma, and 1 patient [20 %] in penetrating trauma. 8 cases[54.5%] in blunt trauma, and 4 cases in penetrating trauma were treated within 24 hours,meanwhile, patients treated after 10 days were 3, all by blunt trauma.The repair of 16 cases were performed with thoracic approach in 4 cases, thoracoabdominal approach in 3 cases, and abdominal approach in 9 cases. The herniated organs in thorax were stomach [5], colon [3], liver [2], and pancreas [1]. Postoperative complication were developed in 9cases[56.3%] significantly related with delayed operation time [p < 0.01 ]. Hospital mortality was 12.5 % [2/16], and the causes of death were hypovolemic shock in one and hepatic failure due to portal vein rupture in another.

승모판막질환자의 체외순환술에 따른 혈중 atrial natriuretic peptide의 변화

이형민,이동협,이정철,한승세 대한흉부심장혈관외과학회 1993 Journal of Chest Surgery (J Chest Surg) Vol.26 No.2

Human atria play an important role in extracellular homeostasis through release of atrial natriuretic peptide. To evaluate the relationship between plasma level of atrial natriuretic peptide (ANP) and many changes which can develop during extracorporeal circulation, we studied 16 patients undergoing, 12 cardiac operation and 4 thoracic operation. Plasma level of ANP in cardiac patients group was significantly higher and more changeable than thoracic patients group. After aortic cross clamp release, blood was filled at right atrium and right atrial pressure was rapidly increased. At the same time, plasma level of ANP was rised suddenly. Increase of ANP level was correlated (p<0.05) with the increase of total bypass time, but was not correlated statistical with aortic cross clamp time. ANP level did not fall rapidly after aortic cross clamp while both atria were completely empty. This result was explained by intraoperative hypothermia at that time, which can inactivate plasmal endopeptidase and catalytic receptors of ANP. The ANP level of atrial fibrillation group in cardiac patients were generally higher than normal sinus group, but there was no statistical correlation.
