It is prescribed in the Article 4 Clause 1 of "act on special cases concerning the settlement of traffic accidents" that a driver who commits a crime by inflicting serious bodily injury through occupational or gross negligence of the crimes relating to traffic accidents shall not be prosecuted in case that he has comprehensive insurance. The law was legislated to fast recovery of the damage given by traffic accidents and to improve convenience in civic life. However, the law has brought undesirable results. It removed criminal responsibility from a driver who caused a grave traffic accident. Consequently, the law hindered driver's awareness of safety, infringed on victims' right to make a statement during proceeding trial and the right of national equality. Recognizing this problem, the Constitutional Court announced the Article 4 Clause 1 of "act on special cases concerning the settlement of traffic accidents" is against the constitutional law. According to the decision of the Constitutional Court, it became possible to prosecute drivers who caused grave traffic accidents. And some changes are expected like decrease of traffic accidents by inspiring awareness of traffic safety, diversification of automobile insurance policy, an increase of the police's work load related to traffic accidents and the specialization of handling grave traffic accidents. If a driver and victim do not come to a mutual agreement, even if the driver has a comprehensive insurance, it is possible to prosecute the driver who caused grave traffic accident so it became important to judge criteria of serious injury in traffic accidents. Except article 258 of criminal law there is no set criteria of serious injury and even article 258 of criminal law does not explain precisely what serious injury is. Moreover, there are almost no judicial cases, related to serious injury caused by traffic accidents, a lack of criteria of serious injury could cause legal disputes. As the Article 4 Clause 1 of "act on special cases concerning the settlement of traffic accidents" is unconstitutional in cases of causing serious injury to victims of traffic accidents, the prosecution sets a guideline concerning serious injury but that guideline is not concrete enough to resolve traffic accidents fairly and accurately. The concept of serious injury should be more concrete and clear than the concept in article 258 of the criminal law, and objective standards and guidelines are needed for this concept. Severity of Disability in the State Tort Liability Act or The Abbreviated Injury Scale (AIS), Injury Severity Score (ISS), which the medical profession uses as a standard of Trauma, can be used as guidelines concerning serious injury. If these guidelines are applied to the Act on Special Cases Concerning the Settlement of Traffic Accidents, it is possible to handle traffic accidents causing serious injury more objectively and clearly. A system in which health and academic experts participate should be set to judge serious injury correctly when the police and the prosecution are resolving traffic accidents.
Accumulator맥동의 Polytropic과정에 관한 연구
윤영환 國立 昌原大學校 産業技術硏究所 1996 産技硏論文集 Vol.10 No.-
Accumulator is a device which smooths pressure and fluid flow in fluid circulation systems. In order to design or size the accumulator, it is necessary to determine the value of n in polytropic process, pvⁿ=C for the air chamber in the accumulator. In this study, the experimental equipment for the value n consists of a solenoid valve, pressure transducers, and a level sensor in the flow circuit, where the solenoid valve gives pulsations to the air chamber. Experimental data from instant pressures and volumes show that the value n approaches n = 1.4 when a pulsation is rapid since its process is similar to a adiabatic process, and the value n approaches n = 1.0 when a pulsation is relatively slow since the process can be said to be close to a constant temperature process. And the sizes of the accumulator computed with measured values n are compared to the size of the tested accumulator. The errors between them are from 6.1% to 26.6%, which become smaller as the pulsation is slow.
기계 열처리 제품에 대한 냉각제의 냉각특성에 관한 연구
尹英煥 國立 昌原大學校 産業技術硏究所 1988 産技硏論文集 Vol.2 No.-
The purpose of this work is to present a transient method for measuring heat transfer characteristic between a hot solid bar and quenching water. Before obtaining the heat transfer coefficient, physical properties (κ,C?,ρ) of a carbon steel bar, which are a function of temperature, are determined by trial and error method. Experiments for the heat transfer coefficients are performed under various flow rates where water temperature is from 3℃ to 20℃. The heat transfer coefficient is simplified into two parts of boiling and convective heat trausfers. Boiling heat transfer is ranged from 0.35 to 0.2 (Cal/㎠·sec·℃), convective heat transfer coefficients from 0.15 to 0.03.

Flow distributions in a rectangular duct with two branches are measured by 5 W laser doppler velocity meter for analysis of fluid flow in air conditioning ducts. The Reynolds numbers of the fluid flow are from 4,226 to 17,491 based on mean velocity and hydraulic diameter at inlet cross-section of the duct. The velocity profiles are obtained at inlet of the duct and both outlets of two branches. From the measurements, it is found that ratios of flow rates distributed into two branches from the main duct are almost invariant to Reynolds number.
직각 엘보우를 가진 사각닥트내의 유체흐름에 관한 삼차원 수치 계산

Three dimensional fluid flow is computed in a rectangular duct with 90˚ wintered elbow by Finite Volume numerical method. The Reynolds number of the fluid flow is 12,186 based on mean velocity and hydraulic diameter of the duct, and the standard K-ε turbulent model is adopted for prediction of turbulent viscosity. The numerical results are compared with experimental data measured by laser doppler velocity meter. The distributions of fluid flow at middle and exit sections past the 90˚ elbow are compared with the experiment data at the same cross sections by taking the measured data at inlet as the inlet boundary conditions of numerical computation. The computed velocity components made relatively good simulation to the experimental data. But, in particular locations, the quantitative agreement between them is less satisfactory. Furthermore, it is also shown that turbulent kinetic energy has similar tendency with turbulent fluctuation components measured by experimental test.
