As a result of increase of high-rise building and complex building in cities, fire damage become larger and complicated. However, law and standards in connection with life safety in the fire is deficient in safety performance and the institution of fire is divided into two parts : the building law and the fire law. The aim of this research is to compare with egress safety rule in advanced countries and to analyze the national standard of egress safety by investigating research data in order to make fire safety rule more effective. On the basis of this analysis, this research also suggested that reform measures should make egress safety in the fire.

The kinetic of the gas phase reactions of ozone(0.5 torr) with sulfur dioxide was studied. The SO2 reaction was conducted in the 7∼22 torr range at 90∼155$^{\circ}$C. The reaction rate was faster than the reaction rate of O$_3$ in the presence of CO$_2$ alone. The reaction of O$_3$ with SO$_2$ follows the rate law: -d(O$_3)/dt=k_0(SO_2)(M)(O_3)+2k _1(SO_2)(O_3$). The first term of this rate law arises from a third order molecular reaction predominating in the lower temperature range and gave a rate constant k$_0$ = (9.35 $\pm$ 8.6) ${\times}$ 10$^9$e$^{-(11.05{\pm}2.04)kcal/RT}(M^{-2}s^{-1}$). The second term of the above rate law derived from a second order thermal decomposition reaction which was the major part of the reaction and gave a rate constant k$_0 =(9.35{\pm}8.6){\times}10^9e^{-(11.05{\pm}2.04)kcal/RT}(M^{-2}s^{-1}$). The overall reaction proceeds with kinetics of complex order composed mainly of second order and third order components.

An avoidance/guidance problem of an aircraft against moving obstacle is considered in two dimensional space. The aircraft is modelled as a point mass flying with constant speed. The lateral acceleration is assumed the control input. Artificial potential functions are applied to the terminal point and moving obstacles in order that repulsive forces and an attractive force are produced by the obstacles and the terminal point respectively. A real time guidance/avoidance law is proposed by using the potential forces and relative velocity. The guidance law for a logarithm potential function results the well-known proportional navigation law. The avoidance control command is inverse proportional to the time-to-go to the obstacle and turns the aircraft toward the negative direction of the line-of-sight change. The performance of the proposed guidance/avoidance law is verified with simulations.

The purpose of this study is to generate a proper regulation improvement direction of the public IT project contract law through the current four contract methods and three methods of the awarding party of a contract method. The research method for this paper is derived from the written materials of the present public IT project contract law. Two problems have been processed in order to produce the results: the current contract methods and the awarding party of a contract method. The current contract methods consist of a competition contract, a private contract, and a supply methodology contract. The methods of the awarding party of a contract display a qualified evaluation regulation, the 2nd step competition bid, a standard cost separation tender, and a contract by a negotiation. The results exhibit that the general competition contract consists of four improvement items. The contract by a negotiation contains five improvement items. The group private contract has one improvement item. And the private contract includes one improvement item. These results implicate that the current public IT project contract law demands better improvement work for the ubiquitous Korea.

The Korea Foreign Trade Act(KFTA) was revised the penal provisions of the breach of the Country of Origin Labeling(COOL) recently. The ceiling of penalties became to 5 years for imprisonment, one hundred or three hundred million won for fine. The level of penalties are adjudged quite fair but the amount of penalty should be increased according to the profits from the breach or the nature of crime in some cases. The problems of the penalties are differences between KFTA and other related laws. There are related several laws on the breach of the COOL such as KFTA, Unfair Trade related Law, Customs Law, Consumer Protection Law, Law of COOL on Agricultural and Marine products etc. The penal provisions of the breach of the COOL has more heavier level than other the breach because of the criminal qualities. The problems are the penalty differences between the KFTA and the Unfair Trade Law under the Ministry of Knowledge Economy. The KFTA's penal provisions need to equate with Unfair Trade Law as long as same breaches on the COOL. The government can also consider some policies to rigid enforcement of breaches on the COOL. There are the Country of Origin Tracking system, the RoO Paparazzi System, Make public the names of habitual RoO Violators, Correction Order of breach of the COOL etc.

Traffic accidents increase with the increase of the vehicles in operation on the street. Especially big traffic accidents composed of over 3 killed or 20 injured accidents with the property damage become one of the serious problems to be solved in most of the cities. The purpose of this study is to build the discrimination model on big traffic accidents using the Quantification II theory for establishing the countermeasures to reduce the big traffic accidents. The results are summarized as follows. 1)The existing traffic accident related model could not explain the phenomena of the current traffic accident appropriately. 2) Based on the big traffic accident types vehicle-vehicle, vehicle-alone, vehicle-pedestrian and vehicle-train accident rates 73%, 20.5% 5.6% and two cases respectively. Based on the law violation types safety driving non-fulfillment center line invasion excess speed and signal disobedience were 48.8%, 38.1% 2.8% and 2.8% respectively. 3) Based on the law violation types major factors in big traffic accidents were road and environment, human, and vehicle in order. Those factors were vehicle, road and environment, and human in order based on types of injured driver’s death. 4) Based on the law violation types total hitting and correlation rates of the model were 53.57% and 0.97853. Based on the types of injured driver’s death total hitting and correlation rates of the model were also 71.4% and 0.59583.

This paper explored the public issue on housework analyzed the policy and the law associated housework and developed the theorical model for its political program. This idea is dependent that the policy has priority over change of the social ideology. That policy contains a campaign and a education to be aimed to share of housework in order to make responsibility of men as well as women on family and work. Also it contains economic value estimates to quantify and value the non-wage work(childcaring homemaking etc.) in order to confirm its productive activity. It would assume the lawful form as like a social security or a pension. For example the Family Rights Law Tax Law and Social Security Act have to be reflected on the value of housework and to be secured the social status of provider. After all this work was useful to improve a wage and a social status of all women. As consistent policy and operation associated housework are poor in Korea it is difficult to develop theoric l model on this theme. On the range a political proposal on housework would be bound by family policy(evaluation of housework) and women's labor policy(housework support). So the policy intend to secure a family life to improve welfare of women and to equilibrate the family and the work.

The purpose of this study is to suggest the revision direction of the Korean Child Welfare Law based on the results of the comparative analysis on the Korean Child Welfare Law and the Japanese Child Welfare Law. The main results are: Both laws have only two provisions about children's participation right. The child protective system in Japan secures the swiftness of within-two-months period of temporary protection through the child consulting center, the investigation right by the child welfare worker, publicity, enforcement on the parents' rights, and the network with the nearest child supporting center. Furthermore, those provisions with the notifying obligation by a finder of the child who needs protection and the limit of protection period are guaranteed in order to ensure the effectiveness of law enforcement. However, Korean child protective system functions only as pre-substitutive service. While the provisions for the disability children account for 21.2% of the total Japanese law, there is no provision on that in the Korean law. The Japanese law is substantially different from the Korean law in a sense that it obligates the minimum quality criteria of child service and national financial burden on the child welfare. While the Japanese law clearly stipulates the national responsibility in relation to the degree of the rights, the Korean law does not directly touch upon it. Furthermore, the Japan's law guarantees that not only children but also protectors retain the right to choose and apply for services.

In this report, a longitudinal adaptive flight control law is presented for the automatic landing system of a Japanese automatic landing flight experiment vehicle (ALFLEX). The longitudinal adaptive flight control law is designed to track an output of the vehicle to a guidance signal from the guidance portion of the automatic landing system. The proposed adaptive control law in the attitude control portion adjusts the controller gains continuously online as flight conditions change, in spite of the existence of unmodeled dynamics. The number of the controller gains to be adjusted is decreased to 1/2 from the previous studies. Computer simulation involving six-degree-of-freedom (DOF) nonlinear flight dynamics is performed to examine the effectiveness of the proposed adaptive control law. In order to verify the influence of the dispersion of the initial conditions, the Monte Carlo simulation is also applied. The initial conditions are more widely dispersed than the previous studies. As a result, except under the unsuitable initial conditions, the ALFLEX successfully landed on the runway.
