폐색전증(Pulmonary Embolism : PE)은 사망률이 높은 질환중 하나이다. 초기에 정확한 진단 및 치료를 시행하는 경우 사망과 재발의 경우가 흔치 않으나 지연 진단이 일어나는 경우 사망률은 높기 때문에 보다 정확하고 빠른 검사법이 필요하다. 본 연구에서는 폐색전증 환자의 흉부 CT 데이터를 가지고 딥러닝 알고리즘을 생성하여 소프트웨어를 구현하고자 한다. 개발된 딥러닝 기반의 폐색전증진단 보조 소프트웨어는 CT 촬영 후 즉각적인 질환 예측으로 판독 시간의 단축과 효율성을 제공 할 것으로 기대된다.

Performance analysis of the interior ballistics has been conducted using the 1-D numerical code called IBcode according to the various conditions such as length of ignition-gas injector, amount of ignition-gas, mass of projectile, and drag force of projectile. In case of the length of ignition-gas injector, the 25~100 % of the full-injector length has been considered as well as the mass & mass flow of the ignition-gas. The mass of the projectile 5~70 kg and its drag force of 0~69 MPa have been also considered. Variables such as breech & base pressure, negative differential pressure and muzzle velocity for the performance analysis have been sorted, too. Firing conditions for the optimal performance have been investigated through these variables.

An aircraft engine is considered as the most important element among aircraft systems. Thus type certificate is required for an aircraft engine to ensure its safety under appropriate airworthiness standard. U.S. FAR Part 33 or European CS-E is widely adopted as an airworthiness standard for aircraft engines, and other representative countries of the world established own airworthiness standards under their regulations. In this paper, we compared differences of the requirements between FAR Part 33 and CS-E, and proposed the rulemaking items to harmonize Korean Airworthiness Standard for Aircraft Engines with worldwide standards and to contribute to growth of aviation industry.

Using the numerical code for the interior ballistics, the performance of the interior ballistics with the characteristic of the ignition-gas injections has been investigated. The ignition gas has been assumed to be injected into the chamber with 3 cases. As the results of analysis, when the ignition-gas has been injected into all chamber area, the pressure distributions of the chamber of the interior ballistics have been uniform and the differential pressure has been stable. The ignition-gas has been injected into the partial area of the chamber, however, the pressure distributions and the differential pressure have been unstable. The case using the longer ignition injector, therefore, seems to be more suitable to improve the stability of the interior ballistics.
