BACKGROUND: Rhinovirus infection of the airways results in increased permeability of the airway vascular endothelium with the influx of plasma proteins, including lipids such as LDL. In vitro studies on the effect of oxLDL on leukocytes has shown many proinflammatory effects on multiple leukocytes. We hypothesized that oxLDL is one mechanism for recruiting granulocytes to the airways during a RV infection. Therefore, chemotaxis and transendothelial migration, in response to nLDL, was determined for these granulocytes. METHODS: nLDL was oxidized with 5mM Cu2SO4 for 20-24 hours. 3-5×10(5) cells were loaded into the Transwell filter while the chemotatic agonists were placed in the lower well for chemotaxis. Confluent monolayers on HPMEC were grown on Transwell filters for transendothelial migration. The filters were washed and eosinophils and neutrophils loaded on to the filter with the chemotatic agonist was were placed in the lower well. The wells were incubated for 3 hours. The number of migrating cells was counted on a hemocytometer. RESULTS: OxLDL, but not nLDL, is chemotatic for eosinophils and neutrophils. The level of granulocytes chemotaxis was dependent on both the concentration of LDL and its degree of oxidation. OxLDL stimulates eosinophil and neutrophils migration across HPMEC monolayers (±IL-1β preactivation) in a dose dependent manner. CONCLUSION: Increased vascular permeability during a RV infection may lead to the influx and oxidation of LDL. The resulting oxLDL. is one possible mechanism for the recruitment of neutrophils and eosinophils to the airway interstitial matrix. Once in the airways, granulocytes can further interact with oxLDL to promote airway inflammation.

Clinincal and radiological findings were analysed in 63 patiets with Osgood-schlatter Disease diagnosed atNational Police Hospital during the period from Jan. 1975 to 1981. The results were obtained as follows; 1. Thedisease was most common between 16 and 20 years, being 39 cases in a total of 63 cases. 2. The ratio of male andfemale was 31:1. 3. Involvement was more often unilateral (45 cases ) than bilateral (18 cases), and the left side(29 cases) was more common than the right side (16 cases). 4. Roentgenogram revealed one or two separated bonyfragments in most cases. 5. Type II by Woolfry and Chandler classification was most common type. 6. The mostcommon clinical findings were pain and tenderness on tibial tuberosity. 7. Trauma history was positive in 11 casesin a total of 63 cases.

Cardiovascular measurement on PA teleroentgenogram of the chest is simple, but very useful in the diagnosis,prognosis, and therapy of hypertensive patients. The authors have measured and calculated cardiothoracic ratio,Lt, to Rt. cardiac diameter ratio, and Lt, aortic knob width to thoracic diameter ration for evaluation of theeffect of blood pressure and age in hypertensive group. We used materials of 70mm fluorography of 255 hypertensivemen above 150/90mmHg chosen from national police hospital during Jan. from Aug. 1981. Their age ranged from 20 to50 yeras. The results were as follows. 1. Cardiomegaly (above 50 percents in cardiothoracic ration) ofhypertensive men is 26%. 2. The cardiothoracic ration increased progressively with blood pressure and age, butpooly correlated between cardiothoracic ration and age than blood pressure. 3. The Lt. to Rt. cardiac diameterration gave similar trend to the cardiothoracic ration. It indicates that hypertensive cardiac enlargement mainlydepned on Lt. Ventricular enlargement. 4. The Lt. aortic knob width to thoracic diameter ration increasedprogressively with blood pressure and age, and had linear correlationship with blood pressure and age. Therefore,prominence of aortic knob is the most significant finding in hypertensive cardiovascular disease.

Pathologists and others have been calling the serous cystadenoma of the pancreas "microcystic cystadenoma", following Compagno and Oertel's proposal in l978 because it usually consists of innumerable small cysts (less than 2cm). However, unilocular or predominantly macrocystic types of serous cystadenoma have been occasionally reported. Therefore, they present a difficulty in precise preoperative and intraoperative diagnosis for their simi1ar gross appearance to other cystic lesions of the pancreas. We discovered two cases of macrocystic and unilocular serous cystadenomas of the pancreas which were lined by cuboidal to flattened epithelial cells. They contained PAS positive and D-PAS negative intracytoplasmic glycogen granules. The unilocular, macrocystic and microcystic patterns may represent a morphologic spectrum of a pancreatic neoplasm. So we propose to use the term "serous cystadenoma" rather than microcystic cystadenoma.

7.The Effect of the Flipped Learning on Self-efficacy, Critical Thinking Disposition, and Communication Competence of Nursing Students.
Journal of Korean Academic Society of Nursing Education 2016;22(4):567-576
PURPOSE: This study was conducted to test the effects of flipped learning for undergraduate nursing students. METHODS: The study was a nonequivalent control group pretest-posttest design. Participants were 140 nursing students (experimental group=70, control group=70). The flipped learning was provided for 6 times (18 hours). Data were collected between March 7 and May 30, 2016. Data were analyzed using Chi-square, t-test, paired t-test with SPSS/WIN 22.0. RESULTS: The results showed that self-efficacy (t=4.67, p<.001), critical thinking disposition (t=6.55, p<.001), and communication competence (t=3.57, p=.001) were significantly higher than in the experimental group than in the control group. CONCLUSION: The study findings suggest that the flipped learning has proven to be influential educational program for improving the self-efficacy, critical thinking disposition, and communication competence of nursing students. The flipped learning was an effective teaching program for nursing student, and need to develop other nursing major subjects.

The aspergillus tracheobronchitis is distinctive manifestation of invasive aspergillosis, in which infection is limited completely or predominantly to the tracheobronchial tree. It accounts for about 7 to 10 percent of cases of invasive disease. Grossly, such disease may take the mucosal exudate and obstruct partially the airway lumen or completely the occlusive mucous/fungus plugs. Microscopically, the superficial portion of the airway wall is acutely inflamed and contain fungal hyphae. However, infection is often limited to the mucosa. We report a case of aspergillus tracheobrochits in a 54 year-old man who presented cough, progressive dyspnea with wheezing, and mucus plug. Bronchoscopy showed mucosal exudate and plug.Bronchoscopic biopsy showed aspergillus hyphae and inflammation in the mucosa. He was successfully treated with itraconazole.

9.Development and Effects of Health Education Program using Flipped Learning for Allergic Rhinitis Patients
Journal of Korean Academic Society of Nursing Education 2019;25(2):173-185
PURPOSE: This study was conducted to develop and test effects of flipped learning on a health education program for allergic rhinitis patients. METHODS: The study was a nonequivalent control group pretest-posttest design, with 38 participants (experimental group: 19, control group: 19). The education program for allergic rhinitis patients with flipped learning developed for this study was conducted in pre-class, in-class, and post-class stages for a total of 12 weeks. For the in-class stage, a TREAT model suitable for patient education program was developed. Data were analyzed with an independent t-test and repeated measures ANOVA. RESULTS: The experimental group showed significant improvement in knowledge (F=15.029, p<.001), self-efficacy (F=6.814, p<.001) and self-care behavior (F=41.761, p<.001). In addition, subjective symptoms (F=61.453, p<.001) and quality of life (F=52.413, p<.001) improved. CONCLUSION: The results of this study show that flipped learning in an education program is an effective method for those in their twenties persistent moderate-severe allergic rhinitis. Therefore, the education program for allergic rhinitis developed by this study is actively recommended for nurses or health managers at universities to educate subjects in their twenties with allergic rhinitis.

Apert syndrome is an uncommon, congenital disorder characterised by malformation of the skull, most often acrocephaly or oxycephaly, in association with symmetrical syndactyly of both hands and feet. It is due to disturbance in the growth of bone and soft tissue affecting principally the head, the hands and the feet. The original description was presented by Troquart in 1886, and acrocephaloyndactyly was named by Apert in 1906. Since then, more than 200 cases have been reported in the world upto 1970. Recently, we have experienced three for typical Apert syndrome and made a brief related literature review
