Owing to the development of Biotechnology, the involvement of humans in life before birth has been increasing. This means the need for the protection of unborn life takes on new importance. The respect for life and human beings which is based on fundamental constitutional principle should still be respected under civil law. This study examines how methods of respect for life are embodied in civil liability law. In particular, it enunciates the protection of unborn life within time-flow. Lastly, it studies the instruments of the civil liability law and the extent of protection for a fetus from the process of fertilization of an ovum by a sperm, development into an embryo and implantation. Especially, it looks into when and how the subject of the right changes. Besides, it critically scrutinizes the opinions of leading case lawyers and the Constitutional Court which conclude that, in order for a fetus to become the subject of Damage law, it is required to be born alive to comply with precedent. Furthermore, it suggests an alternative interpretation theory.

We propose a VSC(Variable Structure Controller) with a PI-type reaching law. In General, conventional VSCs with a reaching law including a discontinuous term have the chattering problem, and thus the system may be unstable due to the disregarded high frequency dynamics in the modeling process. To resolve this problem, the PI-type reaching law is proposed in this paper. The proposed reaching law makes it easy to determine the reaching dynamics as well as the reaching time by utilizing the 2nd-order system analysis. Furthermore, since the discontinous term is not involved in the reaching law, the chattering is considerably reduced. To show the effectiveness of the proposed scheme, the stability of the proposed system is proved by Lyapunov method and the computer simulations are performed for the Ball Balance System.

This study was done to investigate the effects of family relationship on satisfaction with life in women immigrants. The participants were 346 women immigrants in S city, Chungnam province. The data were collected through self-reported questionnaires which were constructed to include such scales as satisfaction with life and family relationship. First, satisfaction with family relationship ranked in order of couple, parents-in-law, and brothers-in-law and sisters-in-law. Second, as the women immigrants were younger, and their wedding time was shorter, satisfaction with couple was higher. Third, when women immigrants were between 20 and 30 years old in age, and between 2006 and 2010 in wedding year, satisfaction with parents-in-law were higher. Fourth, when women immigrants were between 20 and 30 years old in age, and 2006 and 2010 in wedding year, satisfaction with brothers-in-law and sisters-in-law were higher. Fifth, satisfaction with life was higher for women immigrants with younger age, lower educational level, and shorter residence and wedding time. Sixth, curve term more accounted for relationship between satisfaction with parents-in-law and life. Seventh, significant predictors influencing satisfaction with life were satisfaction with couple, and brothers-in-law and sisters-in-law.

The modern version of aircrafts is allowed to guarantee the superior handing qualities within the entire flight envelope by imposing the adequate stability and flying qualities on a target aircraft through the various techniques of flight control law design. Generally, the flight control law of the aircraft in service applies the various techniques of the verified control algorithm, such as dynamic inversion and eigenstructure assignment. The supersonic trainer employs the RSS(Relaxed Static Stability) concept in order to improve the aerodynamic performance in longitudinal axis and the longitudinal control laws employ the dynamic inversion with proportional-plus-integral control method. And, lateral-directional control laws employ the blended roll system of both beta-betadot feedback and simple roll rate feedback with proportional control method in order to guarantee aircraft stability. In this paper, the lateral-directional flight control law is designed by applying dynamic inversion control technique as a different method from the current supersonic trainer control technique, where the roll rate command system is designed at the lateral axis for the rapid response characteristics, and the sideslip command system is adopted at the directional axis for stability augmentation. The dynamic inversion of a simple 1st order model is applied. And this designed flight control law is confirmed to satisfy the requirement presented from the military specification. This study is expected to contribute to design the flight control law of KF-X(Korean Fighter eXperimental) which will proceed into the full-scale development in the near future.

In this paper, we did on the new theory, policy, institution and legal research on the international competition order and justice society for 21st century. At first, we introduced the basic of competition law for fairness of trade in the new international market order under WTO. Secondly, we are researched on the economic approach of the competition law, market competition order and justice society in the new globalism. Third, we studied the international circumstance through the analysis of the patterns of the anti-competition practices and the regulation systems for competition order. We also reviewed the execution criteria and precedents of the fairness theory and competition laws in the USA, EU, Japan, and Korea, briefly. Finally, we presented to the alternative policies that based on our study about the new theory, policy, institution, competition law in opinion from reach the international market competition, fairness society and economic justice for 21st century under WTO.

In 2019, a child died by a school zone traffic accident in Asan, Chungcheongnam-do, the Republic of Korea. Just after the accident, under the name of the "Minsik Law", the Road Traffic Act and the Specific Crime Aggravated Punishment Act were partially revised and went into effect in Korea on March 25, 2020. The new Korean law providing for harsh penalties is designed to reduce automobile accidents in school zones. However, the penalties under the new law seems to be unconstitutionally and unduly harsh. Under the new law, a negligent driver who kills a child at a school zone could be sentenced to indefinite imprisonment, or imprisonment for 3 years or more. The criminal responsibility of a negligent driver at a school zone is the same as serious intentional felonies such as rape, robbery, abandonment resulting in death. Also, even in the case of a school zone accident, if an accident driver complies with the speed limit and other traffic laws and it is impossible to avoid the accident, the driver should not be punished. So, in order to meet the principle of proportionality, the new Korean law should be revised again. In order to find out the appropriate level and punishment method for drivers who cause accidents in school zones, this thesis will compare and analyze the laws of Korea with those of the United States, Germany, and Japan. This paper also reviews the decision of the Constitutional Court of the Republic of Korea in February 2023 that the "Minsik Law" was constitutional. Based on these analyses, this thesis seeks the direction and amendments to properly revise Korean law. In addition, this thesis is intended to present exemplary measures to improve the school zone safety.

The purpose of this study is to analyze the origins and texts of Judaism Mishnah Nashim, to think from the educational theological perspective, to suggest a method to be applied to Christian education, and to analyze human rights issues in relation to women's marriage life. To achieve the goal of this study is first, to analyze the historical process up to the compilation of Mishna Nashim in order to analyze the origin and text of Mishna Nashim, and then, the seven Masekcotts were analyzed from the perspective of the researcher by dividing them into marriage-related civil law, divorce-related civil law, engagement-related civil law, adultery-related civil law, and vow and pledges related civil law in order to analyze the content of the text of Mishna Nashim. Second, in order to analyze Mishna Nashim in educational theology, marriage laws were analyzed by dividing them into brother-in-law marriage system, chastity system of marriage, divorce law, engagement law, adultery law, and vow and pledge law. Third, to apply Mishna Nashim to Christian education, marriage life education were divided into marriage education and divorce education, vow education and pledge education. The conclusion of this study is as follows. First, marriage education is necessary to establish a Christian family. Second, Divorce prevention education is necessary from the Christian point of view. Third, a spiritually healthy vow education must be conducted. Fourth, healthy pledge education is necessary to live as true Christians. As a result, Korean society still has a deep sense of patriarchal authority, and gender equality is still lagging behind. Discrimination, disparagement, taboos for divorce and remarriage, and stereotypes about gender roles of women still exist within the church, therefore, Christianity must provide an alternative solutions solutions.

This paper proposes a novel guidance law based on the block backstepping sliding mode control and extended state observer (ESO), which also takes into account the autopilot dynamic characteristics of the near space interceptor (NSI), and the impact angle constraint of attacking the maneuvering target. Based on the backstepping control approach, the target maneuvers and the parameter uncertainties of the autopilot are regarded as disturbances of the outer loop and inner loop, respectively. Then, the ESO is constructed to estimate the target acceleration and the inner loop disturbance, and the block backstepping sliding model guidance law is employed, based on the estimated disturbance value. Furthermore, in order to avoid the "explosion of complexity" problem, first-order low-pass filters are also introduced, to obtain differentiations of the virtual control variables. The stability of the closed-loop guidance system is also proven, based on the Lyapunov theory. Finally, simulation results demonstrate that the proposed guidance law can not only overcome the influence of the autopilot dynamic delay and target maneuvers, but also obtain a small miss distance.

In this paper we analyze the RHLQG/FIRF optimal.contol law presented in [4,5] in order to stabilizes a stochastic linear time varying systems with modeling uncertainty. It is shown by the frequency domain analysis that the RHC is robuster than the LQ control law. Explicit LTR procedures are given to improve the robust performance of RHLQC/FIRF cotrol law. Using the mismatching function technique [8], we propose an LTR method which makes the RHLQG/FIRF controller recover the feedback properties of the R.HC law. Also we compare the LTR performance of the RHLQC/FIRF via simulation with conventional LTR methods.
