외래에서 흔히 이용하는 결핵 진단법으로는 객담 도말과 배양검사, 엑스선 검사가 있다. 일단 활동성 결핵으로 진단되면 환자의 과거력 등을 참조하여 치료를 하게 되는데, 초치료인 경우 아이나, 리팜핀, 에탐부톨, 피라진아마이드를 이용한 6개월 단기 초치료 처방으로 치료를 한다. 4제 처방의 효과는 강력하여 규칙적으로 약을 복용한다면 대부분 완치되며, 완치 판정은 치료 중 추구 객담검사를 이용한다. 대부분의 환자들은 진단, 치료에 어려움이 없지만 실제 외래 치료시에는 진단, 치료에서 어려운 문제가 발생하기도 한다. 이에 외래에서 부닥칠 수 있는 상황과 적절한 대처법을 알아보기로 한다.

Radar Beacons are marine aids that helps the navigators avoid dangers such as dangerous rocks, heavy fog, nighttime, etc. when sailing. The existing antenna was researching on the development of the advanced radar Beacon (Enhanced Radar Beacon) for the improvement of the next generation racon with the AIS (Automatic Identification System) function.

MOST(Media Oriented Systems Transport) is a network protocol for vehicle multimedia, where it guarantees large bandwidth and reliability. However, previous MOST device utilized I2C or I2S communication method to data manage or transfer, Bandwidth of MOST have increased and additional equipments are added to one device, requiring a larger form of bandwidth communication method. Therefore, this research suggests of the methods in improving the efficiency of asynchronous data transfer, and suggest an algorithm, which will improve the reliability.

This study is to verify the effectiveness of initial planning verification using paper prototyping while methodologies are being developed to verify the direction of game planning in a short time at low cost since it is having a hard time to verify the direction and fun of the game by taking a lot of capital and time in the initial planning process as the game development becomes larger. It conducted paper prototyping production for about 40 students who are learning game planning for a semester, and trained them on how to motivate using core mechanical diagrams, scrums, and basic psychological needs that can effectively materialize the ideas of their early game planning. Through this curriculum, board games were completed with eleven paper prototyping, and it was confirmed that students who participated in the class were meaningful in verifying fun and securing gameability through cross-play.

This paper describes a hybrid cleaning method of silicon wafer combining nano-bubble and ultrasound to remove sub-micron particles and contaminants with minimal damage to the wafer surface. In the megasonic cleaning process of semiconductor manufacturing, the cavitation induced by ultrasound can oscillate and collapse violently often with re-entrant jet formation leading to surface damage. The smaller size of cavitation bubbles leads to more stable oscillations with more thermal and viscous damping, thus to less erosive surface cleaning. In this study, ultrasonic energy was applied to the wafer surface in the DI water to excite nano-bubbles at resonance to remove contaminant particles from the surface. A patented nano-bubble generator was developed for the generation of nano-bubbles with concentration of 1×10⁹ bubbles/ml and nominal nano-bubble diameter of 150 nm. Ultrasonic nano-bubble technology improved a contaminant removal efficiency more than 97% for artificial nano-sized particles of alumina and Latex with significant reduction in cleaning time without damage to the wafer surface.
