Eisenmenger syndrome is a condition which systemic arterial blood oxygen unsaturation occurs if obstruction in the pulmonary capillaries raises the pulmonary vascular resistance and pulmonary arterial pressure to or beyond systemic levels and then a significant right to left shunt develops across a preexisting cardiac septal defect or an aortopulmonary communication-We have experienced 3 cases of similar condition. Case I is 24 year old man who has had cyanosis and dyspnea on exertion since childhood. His pulmonary arterial pressure was 110/80mmHg. He was operated under diagnosis of the mitral stenosis and tetralogy of Fallot, but it was finally discovered that he had patent ductus arteriosus and ventricular defect was closed with perforated prosthetic patch, but the patient expired due to right heart failure low cardiac output. Case II was 16 year old female who had pulmonary hypertension of 110/85mmHg. She was diagnosed as Eisenmenger syndrome combining with atrial septal defect and patent ductus arteriosus. Case III was 20 year old male. His pulmonary arterial pressure was 110/70mmHg and the underlying defect was patent ductus arteriosus.

The purpose of this study is to set a direction for the development of men's underwear after analyzing current applications for patent regarding men's special-purpose underwear. In terms of a research method, the disclosed patents and utility models were investigated using the patent information database provided by Korea Institute of Patent Information (KIPRIS, http://www.kipris.or.kr). For this, the patents applied from 1990 to October 2015 were targeted. The keywords used for patent search were 'men's underwear' and 'men's special-purpose underwear.' When searched by the keywords above, a total of 1,089 cases were found. Except for expired or cancelled ones, 243 cases were investigated. Then, annual application trends, current registrations on literature records, classification of utility model right holders and contents by topic were analyzed. In terms of data analysis, frequency analysis, crosstabulation analysis and multiple response analysis were conducted, using SPSS 18.0. The results found the followings: In terms of annual application trends, the number of applications for patent started to gradually increase since 2007. Since 2011, it has rapidly increased. In terms of the number of patent registrations, literature registration was far higher than utility model registration. In terms of application rights, 'individually registered (58.8%)' was higher than 'registered by the organization (41.2%).' Among 243 cases, 'underwear (58%)' was the highest, followed by 'men's underwear-related items (29.2%)' and 'thermals (8.2%).' According to analysis on the details of the patent applied for men's underwear, 'penis-scrotum separation' was most focused, followed by 'disposable product' 'airy features,' 'scrotum protection' and 'structure of underwear.'

Background: The purpose of this study was to collate inventors' improvements of air extraction cupping technology by reviewing patent applications in Korea. The cost of procurement and use of air extraction cupping devices are covered by health insurance. Methods: Patents registered in Korea for air extraction cupping devices from August 1992 to January 2018 (registration, expiration, rejection, abandonment, and disclosure) were analyzed to determine technology trends. The Korean patent search engine used was Kipris (www.kipris.or.kr). Results: Sixty-seven Korean patents for air extraction cupping devices were retrieved. Most patents focused on design of the top valve of the device, the device at the bottom, an internal device, and the disposable cupping glass. In total 17.9% of patents were registered and 64.2% were abolished [either from non-payment of registration fees (93%) or expiration of the patent after 10 years (7%)]. The average registration period was 3.7 years. Conclusion: The patents retrieved for this study focused on the development of the air exhaust valve, disposable cups, and skin adhesion maintenance technology in cupping devices that use air extraction. The average registration period was 3.7 years, meaning the patents that were not commercialized, expired without additional registration renewals. It is important to acquire a New Excellent Technology certificate for a cupping device to promote commercialization.

Purpose - The purpose of this study is to investigate the types and forms of various marketing activities actually used in pharmaceutical companies and to empirically analyze the impact of these marketing activities on sales. Design/methodology/approach - This study categorize five years' worth of marketing activity data from a foreign pharmaceutical company 'A' which operates in South Korea into five categories. Multiple regression analysis and interaction effects are employed for data analysis. Findings - First, CRM calls, Detail calls, GP, and Web events have a positive impact on sales, but SoV does not show significant differences. Second, in the comparison between HQ1 and HQ2 based on patent ownership, Detail calls and Web events had a stronger impact on sales in HQ2, where the patent period is still in effect, compared to HQ1. However, SoV showed no difference between HQ1 and HQ2. Research implications or Originality - First, Detail Calls are more effective for drugs with active patents, while CRM Calls work better for drugs with expired patents. This emphasizes the need to customize call strategies based on patent status. Second, the significant impact of Web Events on sales in HQ2 compared to HQ1 suggests that online information access is crucial, indicating that customer receptivity varies based on product nature. Third, these insights, derived from data analysis, call for a shift in pharmaceutical marketing analysis methods away from traditional approaches. Finally, this study holds significance as one of the first empirical analyses using actual marketing data from pharmaceutical companies in South Korea.

8개월령 암컷 포메라니안 개가 심잡음과 심비대를 주호소로 내원하였다. 검사결과 좌-우단락 동맥관 개존증과 중등도의 심부전 (ISACHC II) 으로 진단되었다. 잔존 동맥관은 우측 대퇴동맥을 통한 $5mm{\times}3loops$ 코일 색전술을 통해 성공적으로 치료되었다. 2개월 후 환축은 현저한 저혈압과 심한 설사, 흉수가 차는 증상으로 다시 내원하였다. 검사 결과 심각한 폐성고혈압과 삼첨판 역류가 발견되었다. Sildenafil (3 mg/kg, PO, TID) 을 투여함으로써 임상증상은 조절되었으나, 코일빠짐과 보호자의 부적절한 투약으로 인해 환축은 폐사하였다. 부검 결과 폐성고혈압의 원인은 비정상적인 위치로 빠진 색전 코일에 의한 것으로 밝혀졌다. 토이 품종에서 PDA의 치료를 위해 색전 코일이 널리 사용되고 있지만, 장착된 코일이 빠질 위험을 줄이기 위해서는 PDA의 크기와 형태에 대한 한층 더 세심한 평가가 필요하다.

Superior Vena Cava Syndrome: Dacron and Nylon graft between the left innominate vein and the right atrial appendage. Two cases with typical superior vena cave syndrome treated by by-pass graft between the left innominate vein and the right atrial apepndage were presented. One of them was a 58 year old farmer who suffered from marked swelling of the neck and upper half of body, the other was a 50 years old government employee who had acutely progressive symptoms of superior vena cave obstruction. Both of cases revealed that [1] cubitel venous pressure was markedly increased. [2] tumors were noted in the posterior mediastinum by laminography. [3] preoperative cavogram showed the occlusion of superior vena cava and marked collaterals. Dacron and Nylon graft were inserted between the left innominate vein and the right atrial appendage. Postoperatively, the symptoms were relieved markedly, showing edema free face and decreased cubital venous pressure. Postoperative cavogram showed patent graft. Histologically the first case was diagnosed as squamous cell carcinoma and the second as undifferentiated carcinoma, originated probably from bronchus. Total doses of 3150 r X-ray irradiation and 5000 mg of 5-FU were administered in each cases. The first case expired 11 months postoperatively without recurrence of superior vena cave obstruction symptom and the second case is living now without obstruction signs, 4 months after by-pass operation.
