최근 오경 형성사에 대한 연구에 있어 가장 특징적인 현상 중 하나는 제사장 문서/층의 범위를 창세기로부터 시내 산 서사까지로 보는 것이다. 이러한 “짧은 P” 모델을 지지하는 입장에서 이 논문은 두 가지의 모티프를 분석하고 있다. 우선 족장들에 대한 땅 언약으로, 출애굽기 6:8(P)에서는 대단히 중요하게 다루어지지만, 민수기의 제사장 계열 본문들에서는 일관되게 무시된다. 이는 민수기의 본문들이 P와는 다른 시대적 상황에서 후대의 저자에 의해 쓰인 것임을 입증한다. 한편, 회막 문 위에 나타나는 야훼의 영광이라는 모티프 또한 P에 대한 후대의 첨가이며, 따라서 이 모티프가 일관되게 등장하는 민수기의 반역서사들 역시 P보다 후대의 저작이라는 근거가 된다. The recent discussion of the formation of the Pentateuch especially in Europe is marked by the model of “short–P.” According to this model, the Priestly narrative is concluded at the Sinai pericope with the building of the wilderness sanctuary or establishment of its sacrificial system. This model is supported by the motif of the Promise of the Land to the Patriarch. The motif functions as a pivotal link between the Patriarchal and Exodus narratives in P, especially in Exod 6:8. The alleged “P” texts in Numbers are, however, completely and consistently silent about this motif. This phenomenon is not coincidental but reflects different socio–historical contexts and authorship. Also, the motif of Glory of YHWH that appears at the gate of the Tent of Meeting is late addition to P, yet prominent in the rebellion narratives in Numbers. These two motifs argue for the short–P model and the late authorship of the alleged P narrative in Numbers.

The IDB(Integrated Dynamic Brake) is a system designed to control the braking force of a vehicle in order to decelerate the vehicle speed according to the intention of the driver, not the service brake system. The IDB is a system that integrates the separate Master, Booster, and ESC(Electronic Stability Control). Since the IDB is a complicate integrated system, behavior of each component has impact on the system performance. For this reason, predicting the failure of main components in the process of developing the system has become an important challenge. This study introduces an analysis model that verifies the flow of hydraulic pressure in the failure situation of the solenoid valves, which are important components in the IDB. Therefore, this study aims to analyze IDB system behavior through preliminary predictions of the two situations of permanent open and close in the solenoid valve

A two-phase closed thermosyphon (TPCT) is a closed tube which transfers heat by phase changes of working fluid. In this paper, a simulation program is investigated to design TPCT, and de-ionized water is used as a working fluid. The simulation program implemented with MATLAB, and it is evaluated by Kamyar’s (2013) research. The simulation results are presented, which show temperature distribution, boiling and condensation heat transfer coefficient, and total thermal resistance considering de-ionized water as a working fluid. The temperature error between experimental and simulation results were 27%, 14%, 6% on each of evaporator, adiabatic, and condenser of TPCT. Heat transfer coefficients of simulation results were two times bigger than the experimental results. So total thermal resistance of simulation results were two times smaller than experimental results. This simulation program will be used to design and predict the performance of the new TPCT. This new designed TPCT is made of copper tube and its inside and outside diameter are 10.9 mm, and 12.7 mm each. It consists of three parts, evaporator, adiabatic, condenser and its length are 800 mm, 200 mm, and 400 mm each. The input heat transfer rates are 100 W to 5000 W. Later, this simulation program will be developed reflecting the characteristics of various working fluids.
