"Caraka-sa$\d{m}$hit$\bar{a}$ (闍羅迦集)" and "Su$\'{s}$ruta-sa$\d{m}$hit$\bar{a}$(妙聞集)" are the most important medical scriptures in India and are called the three scriptures of Ayuverda including "Astanga-hrdaya-sa$\d{m}$hit$\bar{a}$(八心集)" (which integrates and summarizes internal medicine and surgery.) that is scribed in 8C. Scriptures that have been told today are deemed to be written in 3 ~ 4C. The three scriptures of Ayuverda and "Yellow Emperor's Canon Internal Medicine(黃帝內經)" are very similar in historical position, transmission and separation and addition, pattern and importance of contents, etc, from the aspect of formation and transmission of scriptures when compared with herb medicine. The characteristics that "SuWen(素問)" concentrates on medical theory and "LingShu(靈樞)" focuses on acupuncture therapy are similar with the characteristics that "Caraka-sa$\d{m}$hit$\bar{a}$" values internal medicine and "Su$\'{s}$ruta-sa$\d{m}$hit$\bar{a}$" appreciates surgery. The chapter 8 of "Caraka-sa$\d{m}$hit$\bar{a}$ (闍羅迦集)" is called as 'a volume of completion (or a volume of success)' and describes details of 'pancakarma (which means five representative treatment methods, that is successful regulations of two kinds of basti(灌腸), $\'{s}$irsavirecana(油劑), virecana(下劑), vamana(吐劑). Therefore, the author compares summery of 'internal therapy' of Indian medicine and drug treatment method with Method Of 'Sweat, Vomit And Diarrhea of the representative treatment in herb medicine, based on "RuMenShiQin(儒門事親)" of ZhangZiHe(張子和).

During hydroproof test of composite pressure vessel, acoustic emission signal was measured and analyzed to evaluate structural integrity of composite motor case. When pressure was held for 1 min. at constant pressure from low pressure level to high pressure level, the pattern of hit rate of good composite pressure vessel is increased with higher value than that of bad composite pressure vessel. This report also presents detection possibility of burst location approximately in the range of 25∼36％ of burst pressure using energy rate. In case that it is difficult to detect burst location of composite motor case, it is possible to detect burst location, i.e. structurally weak location of composite pressure vessel with applying same pressure lower than maximum expected operating pressure(MEOP) repeatedly.

Objectives: While cinema is regarded in the contemporary popular leisure activities, the presentation smoking scenes in films has not been fully studied. We investigated Korean box-office hit movies by using content analysis. Methods: We sampled fifty-one hit films played in Korean cinemas during the period 2000-2013. Here, a hit film is defined as a movie viewed by at least 5,000,000 audiences. Results: We found that 78.1% of the Korean hit films contained smoking scenes, whereas only 15.6% of the American hit films were so. Films with the more frequent number of smoking scenes could be lined up in the order of crime, thriller, and action genres (p<.05). Smoking actors were leading roles, hence attractive characters appealing to the audience. Moreover, the smoking rate of female characters in the films was determined to be 3.66 times greater than the actual smoking rate of females in reality. Conclusions: Smoking scenes are likely to affect the audiences' cognitive priming and/or social learning with respect to smoking. Therefore, it would be necessary to set a restriction standard to the frequency of smoking scenes to appear Korean films, and to consider it as an important factor in the assigning a screening grade to such films.

Let $D_3$ be the Dickson invariant algebra of $F_2[X_1,\; X_2,\; X_3] \; by \; GL(3,\; F_2)$. In this paper, we provide an elementary proof of Theorem 3.2 of [2]; each element in $D_3$ is hit by the Steenrod square in $F_2[X_1,\; X_2,\; X_3]$.

Mathematical models for hit probabilities of small arms are developed in order to estimate the expected hits on an aircraft for certain altitudes and air speeds. A model for the firing lead angle is developed for cases when the distribution of hits is normal and the firing angle is from 20 degrees to 160 degrees. probabilities of hit for single and multiple shots at various altitudes are calculated. Tables are given showing the probability of hits and kill for targets flying at high speed above 500 feet from ground level.

HIT(Heterojunction with intrinsic thin layer) solar cell은 결정 실리콘 (c-Si)을 n-type으로 제작시 수율이 어렵고 결정 실리콘 (c-Si)을 p-type위에 제조하는 것이 보다 보편적인 방법이므로 베이스의 결정 실리콘에는 p-type을, 그 위에는 진성 층(intrinsic layer) 그리고 반투명 전극의 아래에 제조되는 비정질 실리콘 (a-Si)을 n-type으로 하여 베이스 층과 TCO 후면 층의 두께, 도핑 농도 (doping concentration)와의 관계를 확인하여 본다.

The synthesis of the 3D images is the most important part of the virtual reality. The ray tracing is the best method for reality in the 3D graphics. But the ray tracing requires long computation time for the synthesis of the 3D images. So, we implements the ray tracing with software and hardware. Specially we designs the hit-test unit with FPGA tool for the ray-tracing.

본 논문에서는 일본의 Sanyo사에서 발표한 HIT(Heterojunction with Intrinsic Thin layer)구조를 기반으로 하여 태양전지의 output특성을 분석하고자 한다. HIT 태양전지 구조의 경우 a-Si층이 태양전지의 효율과 개방전압 $V_{oc}$의 향상에 중요한 역할을 한다. 본 연구를 통해 a-Si층 내에서의 두께변화가 태양전지 output특성에 어떠한 영향을 주는지 비교해보고, 최고 효율을 낼 수 있는 구조를 찾고자 한다.

This paper aims to analyse the performance of coded frequency hopping /spread spectrum mul~ tiple access system by employing the channel with mixture of A WGN, partial band jamming, fading and user interference. In this approach, a special consideration is focused on the effect of the partial hit. That is, the interfering signals that are present for a small fraction of the hop dur~ ation did not cause hit. The results of analysis showed that the frequency hit changed linearly according to the varying degree of frequency overlap. And this effect did not change the type of error probability distri~ bution.
