This study is based on the need to Lawively respond to changes in the population structure according to the low birth and elderly society, and to contribute to the establishment of policies on the welfare of the elderly, based on the need to review the "Elderly Welfare Law", and proposed ways to improve them by looking for problems with the Elderly Welfare Law. First, it is the enLawment of the Basic Law on The Welfare of the Elderly. As a proposal to improve the Elderly Welfare Law, it is a way to completely revamp the Elderly Welfare Law to grant a status as the basic law and the supreme law on the welfare of the elderly. Second, it is necessary to overhaul the law on elderly health and welfare measures and elderly welfare facilities. The plan is to revise the Elderly Welfare Law to clearly revise the legal charLawer of the elderly to the health and welfare measures of the elderly and the Law on elderly welfare facilities. Third, the legal system of the Elderly Welfare Law should be reorganized. The plan is to maintain the contents of the major welfare policies contained in the current "Elderly Welfare Law", but to revise it with a focus on the systemic issues mentioned above. In conclusion, the current "Elderly Welfare Law" was made in the context of the period at the time of its establishment and the basic courtesy of the elderly, and there are many points that are insufficient to cope with the low birth rate and the elderly society. Accordingly, this study proposes amendments and supplements to the Elderly Welfare Law, which can accept the request stipulated by the times due to changes in population structure.

Attitude control law synthesis for the three-axis attitude maneuver of a flexible spacecraft model is presented in this study. The basic idea is motivated by previous works for the extension into a more general case. The new case includes gravitational gradient torque which has significant effect on a wide range of low earth orbit missions. As the first step, the fully nonlinear dynamic equations of motion are derived including gravitational gradient. The control law design based upon the Lyapunov approach is attempted. The Lyapunov function consists of a weighted combination of system kinetic and potential energy. Then, a set of stabilizing control law is derived from the basic Lyapunov stability theory. The new control law is therefore in a general form partially validating the previous work in some sense.

Purpose: This study aimed to assess the awareness of good Samaritan law and attitude toward basic life support (BLS) of university students. Methods: A 29-item questionnaire survey was conducted among 147 students in A university. The participants were freshmen and sophomores who had received cardiopulmonary resuscitation (CPR) training in middle or high school. Statistical analysis was carried out using SPSS 21.0. Results: The majority (85%) of the participants knew about the good Samaritan clause in the Emergency Medical Service Act, but only about half (58.5%) knew about the Non-rescuer Act. Almost all of the patients said they would administer CPR to patients and showed a positive attitude toward BLS (3.74±0.40). Conclusion: Greater help attitude was exhibited by those who knew the good Samaritan law. These findings suggested that such education may increase their likelihood or helping in emergencies.

In the recent years, China's aviation industry has gained visible progress. Meanwhile, China's aviation law system has become more and more complete. However, in this system, many problems still exist, especially lacking a unified aviation law, which limits the development of China aviation industry, general aviation in particular, and hinders the economic growth. This article aims to raise the basic structure of China's unified aviation law system and proposals on the basis of analysis on the existing problems in our current aviation law system.

This paper aims to explore the cause and aspect of inter-ministerial policy conflict and its coordination in science and technology policy-making with the case of science and technology basic law-making process in Korea. This law-making processes are analysed through the three periods for the last 10 years starting 1992, such as law-formulation(1st) period, interim law-making (2nd) period, and final law-making(3rd) period. Based on these steps, it tries to concretely describe the phenomenon of policy conflict and the coordination mechanism among government departments and analyses the characteristics of dynamic interaction and mutual adjustment among the related agencies. The analysis is mainly focussed on the underlying causes and determinants of policy conflict, the development and coordination process of the conflict, the strategies and logics of the conflict participants, and eliciting some policy implications for effective policy coordination among government departments. Research results are summarized as follows. First, in science and technology policy-making the main causes of policy conflict among government departments are attributed to the difference of policy-orientation and jurisdiction-orientation of each agency. During the first period, the main aspect of policy conflict was policy-oriented, during the second, the main aspects of policy conflict were both policy-oriented and jurisdiction-oriented, and during the third, policy-oriented conflict was dominant. Second, the dominant typology and strategies of policy coordination which the participants used were vertical-political and horizontal-analytic approach. During the first period, horizontal and analytical approach were used, during the second, horizontal and political approach are mixedly used, and during the third, vertical and political approach were dominantly used. Third, The Korean National Assembly and the ruling party played a pivotal role in science and technology policy-making process(the basic law-making process) in particular during the final period.

This study has examined experimentally the Beer's law which is a precondition for quantitative electron tomography. We used carbon support film and latex spheres, which have similar absorption coefficients with biological samples, as the test samples to take a tilt-series of images for electron tomography. First, the 3D information of carbon film and latex spheres was obtained by electron tomography. Then, the regression analysis on the relationship between the intensities of the incident and the transmitted beams in a tilt series was carried out to examine the Beer's law. The regression results with RMS error of 0.976 show the linear intensity variations of the transmitted beam as the tilt angles were increased. In addition, the relative absorption coefficients of carbon support film and latex spheres calculated experimentally through the Beer's law were 1.71 (5) and 2.67 (6)/${\mu}m$, respectively. The absorption coefficients remained constant within a full tilt range. Therefore, it is expected that quantitative electron tomography could be performed for biological samples by applying Beer's law provided the exact intensity of incident beam can be obtained under the thoroughly controlled experimental conditions.

In this era of changing system, we may learn lesson from newly developed Uniform Electronic Transation Act(UETA) in 1999. Korea has its counterpart as the Basic Electronic Transaction Act and Electronic Signature Act made by 1999. While UETA stresses on transaction law between individuals, that of Korean stresses on the role of government in electronic transaction. Both laws have the common definitions as electronic record, electronic signature, however, UETA has its own definitions such as automated transaction, computer program, electronic agent, information, information processing system, and security procedure. Especially, transferable record in section 16 is one of the most unique concept which Korean law does not provide. Korean government is planning to introduce electronic note in the near future, which will make unprecedented reform in Korean financial industry. Since Korean law does not have such a concept as electronic note, revision of the law is expected soon. Korean law has its specialty which puts stress on cyber mall, authentication agency, and consumer protection. In U.S., the interpretation of law by court is important when they have disputes according to common law traditon. Studies on cases on disputes in U.S. is needed most for Korean application.

Cyber space is a place where free activities are guaranteed. However, it is also true that not all individuals and countries strive for peaceful cyberspace, and that there is a growing tendency to gain unfair advantage through this space. Therefore, the state should reform laws and institutions to keep cyberspace safe. By establishing the "Basic Law on Cyberspace" which includes the law of the state law on cyberspace, it is necessary to be able to recognize and respond to the direction of the national legal discipline on cyberspace. The development of digital forensics is an urgent task due to the rapid development of IT. However, if the law is delayed for various reasons, some of the existing laws should be amended to improve the stability of the law in accordance with the circumstances. To this end, it is necessary to revise the "Information and Communication Infrastructure Protection Act", "Information and Communication Network Enhancement and Information Protection Act", "Integrated Defense Law", "Establishment of Defense Information Infrastructure Infrastructure and Defense Information Resource Management Act".
