Cho Gwang-jo(趙光祖, 1482-1519) was the moralist who had the purest conscience and aimed the devoted politics among many fellow Confucianists of Chosun Dynasty. He even criticized his teacher who was in his late forty years for not being able to control his emotions when he was just a teenager. That is to say, he was the one who have kept his cold reasons for entire life. Nevertheless, as mentioned before, Cho Gwang-jo was very faithful to his emotions and also very honest. We find that he was definitely emotional. He demanded to change the relationship between the king and the courtier to the one between the father and the son with humane communication. He expressed his mind and emotion he had used to have at the moment of his death: he loved his king just as he loved his father. However, the king, Joongjong, was indifferent at the human's emotion as if he was a senseless figure. That was the saddest frustration and grief he had. However, his grief did not remained just as the mere grief but again survived as the hope for the survivors and descendants with the big echo. In this respect, his gried did not just end as the grief but it can be said that it even revived itself as the strength and courage. Then, Cho Gwang-jo's life as a human being was never a failure. Moreover, his grief and agony did not just remained as the vain emotion and sadness.

Pure esophageal atresia without tracheoesophageal fistula is a uncommon form of congenital malformation of the esophagus, which is able to be suspected by fetal ultrasonograpy before delivery and diagnosed definitely by simple chest X-ray and esophagogram immidiately after delivery. We performed delayed primary repair in 2 cases of pure esophageal atresia by using stomach for conduit in one case and colon in the other case. But there were graft failure in the latter case, so reoperation was performed by using stomach. Postoperatively, two patients showed no stenosis and leakage in anastomotic site and were discharged in good oral intake without dysphagia.

In this paper, a theoretical method is presented to design a hydraulic control valve system that consist of an important component in the hydraulic snubber. The hydraulic snubber is used essentially to support the piping systems at power plants. To calculate the force due to pressure drop and flow rate in the valve orifice and by-pass hole, Bernoulli equation is used. The Reynolds equation are numerically analyzed in the clearance gap between the valve cone and valve seat to estimate the friction force and leakage flow rate. Based on the detailed theoretical data, we developed successfully the hydraulic snubber for power plants.

This study was conducted to establish an individual identification system comprising of 19 microsatellite markers located on different bovine autosomes. The markers were typed on 257 animals from five cattle breeds. In total, 112 alleles were detected from the genotyping of 19 microsatellite markers. The average heterozygosities ranged from 0.292 to 0.824 and the polymorphic information content (PIC) ranged from 0.274 to 0.817 in Hanwoo. We found that there were differences in allele frequencies in Hanwoo when compared with other cattle breeds. The calculated cumulative power of discrimination (CPD) was 99.999% when nine microsatellite loci were used for analysis in the individual identification system. Also the matching probability, the probability that two unrelated animals would show the same genotypes, was estimated to be $0.44{\times}10^{-9}$. Therefore, the nine markers used in this study will be used for individual identification in two million Hanwoo individuals.

Among the late postoperative complications of the acute dissection of aorta, the fistula between dilated distal aorta and pulmonary parenchym is so rare that only few case have been reported sporadically. Although the aortopulmonary fistula is one of a fatal condition that needs prompt surgical intervention, with an appropriate management it is well controllable condition. Early diagnosis and urgent surgical intervention is the only way to prevent catastrophic hemorrhage. We experienced a surgical management of aortoplumonary fistula which occurred between upper lobe of the left lung and distal aortic dilatation of previous aortic bypass graft which was performed for Debakey type I acute aortic dissection.

Infection of both native and prosthetic vessels in the groin is a very serious disease because of recurrent arterial rupture and sepsis, which can cause death. The successful treatment of groin infection, including infection of the femoral artery, requires extensive excision of the infected tissues and restoration of the circulation where the infected area is isolated. Here we describe a case of obturator bypass in a patient with infected femoral artery rupture that occurred after extracorporeal membrane oxygenation for myocarditis and severe heart failure.

In this study, we conducted to the development of a rapid antimicrobial susceptibility test method using WST-1 which is known to water-soluble tetrazolium salt, in order to rapidly response against bacterial diseases in fish. Eight of antibiotics which are permissioned for marine organism from government were used to rapid antimicrobial susceptibility testing using the WST-1. As a result, a similar tendency was verified compare to conventional antibiotic susceptibility test results. Generally, the antibiotic susceptibility test method required about 3 days (72 hours) for determine the effective antibiotics, however, we have confirmed that the our method using WST-1 was required at least 36 hours in this study. Consequentially, our method will contribute to development of rapid antimicrobial susceptibility testing for bacterial diseases in fish.

A clinical analysis was performed on 383 cases of chest injurjes experienced at Department of Thoracic Surgery, Seoul National University Hospital during 21 year period from 1957 to 1977. Of 383 patients of chest injuries, 209 cases were result from nonpenetrating injuries whereas 175 were from penetrating injuries, and there were 258 cases of hemothorax or/and pneumothorax, 162 of rib fracture, 33 of foreign body, 26 of clavicle fracture, 26 of lung contusion, 17 of diaphragmatic laceration, 14 of hemopericardium, 14 of flail chest and others. Stab wound was the most common in penetrating injuries and followed by gunshot and shell fragments. The majority of nonpenetrating chest injury patients were traffic accident victims. and fails accounted for the next largest group of accidents. Chest injuries were frequently encountered in the age group between 16 and 50 years, and 321 patients were male comparing to 62 of female. In blunt chest injuries the patients with five or more rib fractures had a 85 per cent incidence-of intrathoracic injury and 19 per cent had an intraabdominal organ damage, whereas those with four or less rib fractures had a 69 per cent and a 6 per cent incidence respectively. The principal associated injuries were cerebral contusion on 19 cases, renal contusion on 10, liver laceration on 7, peripheral vessel laceration on 5, spleen laceration on 3 and extremity fracture on 18 patients. The principles of therapy for early complications of chest trauma were rapid reexpansion of the lungs by thoracentesis [46 cases] and closed thoracotomy [125 cases] but open thoracotomy .had to be done on 90 cases [23-5%] because of massive bleeding or intrapleural hematoma, foreign body, cardiac injury, diaphragmatic laceration and bronchial rupture. The over all mortality was 2.87 per cent [11 among 383 cases], 8 cases were from penetrating injuries and 3 from nonpenetrating injuries.

We investigated whether Bacillus spp., newly isolated from Korean traditional food resources, influence the resistance of hosts to foodborne pathogens, by using Caenorhabditis elegans as a surrogate host model. Initially, we selected 20 Bacillus spp. that possess antimicrobial activity against various foodborne pathogens, including Staphylococcus aureus. Among the selected strains, six strains of Bacillus spp. used in preconditioning significantly prolonged the survival of nematodes exposed to S. aureus. Based on 16S rRNA gene sequencing, all six strains were identified as B. licheniformis. Our findings suggest that preconditioning with B. licheniformis may modulate the host defense response against S. aureus.
