Self-defense is defined as 'an act which is performed in order to prevent impending and unjust infringement of one's own or another person's legal interest'(Article 21, the Criminal Act). To establish such a self-defense, it is generally suggested that it requires an intent for defense as subjective element as well as objective precondition of impending and unjust infringement of one's own or another person's legal interest' and considerable reason. Intent for defense which means an awareness for objective circumstance of self-defense is recognized as objective justification element for self-defense. With regard to intent for defense, there are various discussions on not only necessity of such an intent for defense but whether it is necessary for both actor's recognition of circumstance and specific purpose or motive and which should be applied for its punishment in case of lack of the intent for defense: consummated, unconsummated or semi-consummated. However, there is no clear regulations. This article reviews the contents of intent for defense based on opinion that it is necessary for intent for defense and then examines contents on criminal effect in case of lack of intent and intent for defense in case of criminal negligence.

본 연구에서는 미계측 산지 소유역에 대하여 수자원 개발과 이용을 위한 일 유출량 산정을 하였으며 연구의 대상유역은 충주댐 유역중에서 비교적 산지의 분포가 많은 농촌 계곡 유역이며, 특히 덕주골, 만수골, 고무서리골과 같은 유역은 유량계측 시설이 없는 미계측 유역으로 수자원 계획수립시 유출량 산정에 어려움이 있는 곳이다. 이러한 미계측 계곡 소유역에 대하여 강우자료와 지형특성을 이용하여 기존의 유사한 유역이나 기수립된 모형의 매개변수를 이용하여 산지계곡 유역에 탱크모형을 구축하여 저수유출 해석을 실시하여 유출량을 산정함으로써 수자원계획 수립에 이용할 수 있도록 모형을 구축하였다. 탱크모형에 의하여 유출량을 산정한 결과 비유량법과 면적비에 의한 유량이 모두 비슷한 양상을 나타내는 것으로 분석되었다. 미계측 산지 계곡의 유량을 산정하는 데 있어 실측한 자료의 부정확성을 탱크모형에 의해 모의하여 보완하여 유출량을 산정하여 수자원 계획수립에 도움이 될 것으로 판단된다.

In this study, the performance of a low-floor midsize bus under development is predicted through simulations. To predict the vehicle's acceleration, maximum speed, and uphill driving performance, a forward simulator which calculates the vehicle power is developed. Also we verify the forward simulator by comparing simulations and test result for benchmarking vehicle. To predict the fuel consumption, we use a backward simulator for a specified road cycle. However, to predict the fuel consumption using the backward simulation the engine fuel-consumption map is needed. The engine fuel-consumption map extracting data from a similar sized diesel engine is used by re-scaling the maximum torque. As a result, we simulate the vehicle's forward performance with a new engine. Further, we simulated the backward performance to optimize the fuel efficiency and gearshift timing.

This paper propose a new taegeuk shaped directional couper and verify the possibility of high power division rate in those directional coupler through the experiments. We took the taegeuk shaped structure in those proposed directional coupler to utilize a $3\lambda/4$ section of hybrid ring directional coupler actively, and calculated the branch admittances, which satisfied the condition of perfect matching and isolation in the center frequency, by even odd mode analyzing methodes. On the result, we knew that it can be realized a much higher power division rate than reported result in same circuit area within the producible resistance limit in the microstrip line, made the taegeuk shaped directional couplers with 0, 8, 16 dB power split ratio in the 10 GHz frequency using CGP - 502 plate, and confirmed the validity of theory through the experiments.

Recently, parallel computing using GPGPU(General-Purpose computing on Graphics Processing Units) according to the development of the graphics processing unit is expanding. This can be achieved through the processing speeds faster than traditional computing environments across many fields, including science, medicine, engineering, and analysis. However, in using the GPU technology to implement the a parallel program there are many constraints. In this paper, we port a CPU-based program(Video Quality Measurement Program) to use technology. The program ported to GPU-based show about 1.83 times the execution speed than CPU-based program. We study on the acceleration of the GPU-based program. Also we discuss the technical constraints and problems that occur when you modify the CPU to the GPU-based programs.

The pollinating activity of bumblebee, Bombus ignitus was investigated at the blossom of Peach [Prunus persica (L.) Batsch] planted in vinyl house. The major time of foraging activity by B. ignitus was between 08:00 and 7:00, and the peak time of pollinating activity by B. ignitus was 11 :00 in the peach vinyl house from February 28 to March 5 in 2002. The rate of fruit set and the rate of marketable fruit by foraging activity of B. ignitus were much better than artificial pollination, and the effect of labor reduction by the pollinating activities of B. ignitus released against th ε artificial pollination was took remarkable profits over 93%. Therefore, the foraging activity of B. ignitus in peach vinyl house brought satisfactory results among the rate of fruit set, the rate of marketable fruit and the effect of labor reduction against the artificial pollination.

Objective : The purpose of this study is to establish a category for acupuncture therapy by appropriate etiological analysis and differenciation of edema. Methods : We arrange Huang Di Nei Jing and thirty four kinds of literature about edema. Results : 1. The cause of Edema is functional disorder of lung, spleen, kidney, bladder and tri-energizer by six kinds of natural factors, internal injury and loss of nutritions. 2. Edema compartmentalize into the water of five zang organs, several kinds of edema(e,g. 5, 10, 12, 24) and yang & yin edema. 3. An ultimate cause of edema pathogenesis is the disturbance of Qi function in kidney. 4. In view of the results so far achived,'GV26(水淸)' is a vitally important acupoint in acupuncture treatment of edema.'GV26(水淸)' and 'CV9(水分)' are very useful acupoints in moxibustion. 5. In the acupuncture and moxibustion treatment of yang edema, we can use acupoints as like 'GV26(水溝)', 'S36(足三里)', 'B20(脾兪)' and 'SP9(陰陵泉)' by purgation and reduction for expelling wind, reducing fever and eliminating dampness. In an instance of yin edema, we can use acupoints as like 'CV9(水分)' 'S36(足三里)', 'CV6(氣海)', 'B20(脾兪)', 'B23(腎兪)' and 'K3(太谿)' by reinforcement for tonifying spleen yang-middle energizer-, qi-transmission and water promoting.

This article focused on the development and current status of Sijo-chang, the Korean classical vocal genre, which is the text as a fixed form of Korean classical poems. Historically, Sijo-chang has originally emerged from Hyangga鄕歌 during Silla period (BC. 57- AD. 935). However, the current Sijo-chang has been developed from the latter of Joseon朝鮮 period(AD. 1392-1910) in 1800s. Since 1800s, Sijo-chang derived from the Gyeong-je Pyeong sijo京制 平時調, which was established in Seoul, was able to accelerate its musical types and regional characteristics among the Korean peninsula. By setting a clear division of two time periods between 1800s and those periods since 1900s to today, this article mainly explains how Sijo-chang has been developed historically. First of all, in order to appraise the musical styles and characteristics of Sijo-chang in 1800s, comparing the current musical types of Sijo-chang and those printed old score books which has its historical musical characteristics during 1800s is necessary. Secondly, this paper concentrated on the transmitted lineages of representative vocalists among the regional-based Sijo-chang from 1900s to today. During those periods, the Sijo-chang has formed its particular regional-based musical characteristics among the Korean peninsula such as Yeong-je嶺制 of Gyeongsang province慶尙道, Naepo-je內浦制 of Chungcheong province忠淸道 and Wan-je完制 of Cheolla province全羅道. Although it was not a type of regional-based Sijo-chang, as a creation with reference based on certain regional types of Sijo-chang in 1960s, this paper introduced the inheritance process of Seogam-je石菴制 which was made by Jung Gyeong-tae鄭坰兌 named Seogam石菴 as his pen name. Since Seogam-je has been singing as the most influential musical types of Sijo-chang through the mainly southern region of Korean peninsula and even in Seoul, it was highly significant to research it. In addition, this paper elaborately highlighted the developments of various Sijo-chang based on its historical performances, studies, and the composed pieces from the early 1900s or the mid-1900s. In conclusion, in order to set a vigorous development of Sijo-chang, this paper raised several concerns among the future of Sijo-Chang and the significance of its traditional value.
