  • Chapter 1 in Article 2 of forest law defines the definition of forest. but its meaning is so wide that it itself containg a lot of contradiction in it. And it lose legal adaptation which gives a lot of hindrance with criminal investigation. Furthermore, it has made extension of ferming lands, and promotion of livestocks which are most important matter to be solved in Korea retarded. Such an act made us bewildered to adapt concerned laws being applied to out law. This is to form a basic principal and define its correction. It is required that forestry of Korea should be utilized valuable and reserve forest region instead of definition totally, and the purpose of reforestation should be clear. In addition to above, it is required to define what forestry is, in the direction of reconstructing forestry better in Korea.

  • In this paper, a game optimal receding horizon guidance law (GRHG) is proposed, which does not use information of the time-to-go and target maneuvers. It is shown that by adjusting design parameters appropriately, the proposed GRHG is identical to the existing receding horizon guidance law (RHG), which can intercept the target by keeping the relative vertical separation less than the given value, within which the warhead of the missile is detonated, after the appropriately selected time in the presence of arbitrary target maneuvers and initial relative vertical separation rates between the target and missile. Through a simulation study, the performance of the GRHG is illustrated and compared with that of the existing optimal guidance law (OGL).

  • The present study investigates the effects of Cattaneo-Christov thermal effects of stagnation point in Walters-B nanofluid flow through lubrication of power-law fluid by taking the slip at the interfacial condition. The impacts of thermophoresis and Brownian motions are further accounted. The fluid impinging orthogonally on the surface is due to power-law slim coating liquid. The generalized newtonian fluid equation is used that obeys the power law constitutive equation to model our problem. The effect of velocity profiles, temperature for different values of n are investigated. The prandtl on the temperature distribution for partial slip and no slip cases is also observed. It is found that for larger values of prandtl number thermal diffusivity of fluid reduces and it enhance the decrease in temperature and boundary layer thickness.

  • Subsequently in Korea product liability has been introduced. The position of consumers for defective products have been disadvantageous. Defective products should be broght under the law. Then, while consumers would be largely protected, a producer would take the heavy responsibility by law, Therefore, a producer would not be able to take countermeasures for product liability. Object of this paper to investigate and analyze the actual state of management for product liability in advanced countries, and to join it with our quality management system.

  • Liquid metal-cooled reactors use various passive safety systems driven by natural circulation. Investigating these safety systems experimentally is more advantageous by using a simulant. Although numerous experimental approaches have been applied to natural circulation-driven passive safety systems using simulants, there has been no clear validation of the similarity law. To validate the similarity law experimentally, SINCRO-V experiment was conducted using Wood's metal and water for simulant of the Wood's metal. A pair of SINCRO-V facilities with length-scale ratio of 14.1:1 for identical Bo' was investigated, which was the main similarity parameter in temperature field simulation. In the experimental range of 0.2-1.0% of decay heat, the temperature distribution characteristics of the small water facility were very similar to that of the large Wood's metal facility. The temperature of the Wood's metal predicted by the water experiment showed good agreement with the actual Wood's metal temperature. Despite some error factors like discordance of Gr' and property change along the temperature, the water experiment predicted the Wood's metal temperature with an error of 27%. The validity of the similarity law was confirmed by the SINCRO-V experiments.

  • China's airline industry is experiencing a booming development as one hand, on the other hand the incidents involving unruly behaviour on board aircraft also becomes a growing concern for the whole industry. The thesis examines the basic issues concerning the unruly behaviour, such as definition of unruly behaviour, the impact and root causes of unruly behaviour. Then it focuses on the China's legal sources governing the problem of unruly behaviour. Generally speaking, China's legislation with this respect is systematic and self-contained, except some minor shortcomings which need to be revised. Finally the thesis holds the view that the preventative measures jointly contributed by all the parties concerned are something more important than the legislation itself.

  • Patent infringement is defined as implementing a whole patent product without authorization, which is called literal infringement. However, the alleged infringer sometimes does not directly produce the same product with the patented invention, but they simply replace some claimed elements with new materials, or they only produce a certain part of the patent product. Therefore, there is an issue on whether the above cases should also be deemed as patent infringement. This paper uses specific cases to analyze the formation and development process of the doctrine of equivalents and indirect infringement theory in Japan. Then, by discussing the interpretation of Article 101 of the current Japanese patent law, this paper makes it clear that whether it constitutes direct or indirect infringement in some particular cases. The objective of this paper is to clarify the specific requirements of patent infringement under Japanese patent law by case studying and comparing with the patent legal system of China.

  • The effect of fluctuating temperature on the respiration of vegetables has been investigated. Spinach was selected as the experimental material because of its high respiratory activity and kept under the condition that temperature changed alternately at low and high levels every 4 hours. The low-high level temperature combination was set in $1-10^{\circ}C,{\;}1-20^{\circ}C{\;}and{\;}1-30^{\circ}C$. Respiration was evaluated in terms of quantity of $CO_2$ evolved from spinach. The evolution rate of $CO_2$ was determined by a change in its concentration. The evaluation rate of $CO_2$ followed closely the temperature change. In the temperature combinations at $1-10^{\circ}C{\;}and{\;}1-20^{\circ}C$, the relationship between $CO_2$ evolution rate and temperature was found to be able to express by Arrhenius law, while at $1-30^{\circ}C$, it did not obey the law.
