Under the conflicting objectives of maximum user satisfaction and fast launching, there exist great needs for automated mobile app testing. In automated app testing, detection of usage-state changes is one of the most important issues for minimizing human intervention and testing of various usage scenarios. Because conventional approaches utilizing pre-collected training examples can not handle the rapid evolution of apps, we propose a novel method detecting changes in usage-state through graph-entropy. In the proposed method, widgets in a screen shot are recognized through DNNs and 'onverted graphs. We compared the performance of the proposed method with a SIFT (Scale-Invariant Feature Transform) based method on 20 real-world apps. In most cases, our method achieved superior results, but we found some situations where further improvements are required.

This paper presents development status of sounding rockets containing scientific payload and telemetry at home and abroad. The case of outside, united state is launching sounding rockets in 20-30 flight per year by the NASA program which offer to carry payload weights of 38-680 kg and altitude of 88-1,500 km. Europe is launching in 4-5 flight per year by the ESA program. Japanese sounding rockets are being applied an Antarctic exploration and flight verification in 1-2 flight per year. The case of korean sounding rockets was successful with the launch of three times(KSR-I,II,III), but our development techniques for space launch vehicle lag behind other industries. Therefore, Launch vehicle development should enable with the support and acquirement of advanced technology.

The launching of the Taepo-dong 1 on 31 August 1998 by the North Korea was the first case where the diplomatic protests was made against the flight, the purpose of which, the launching State claimed, consisted in space exploration and use. It is the principle regarding the freedom of space exploration and use, as included in the international treaty, that is relevant in applying the various rules and in defining the legal status of the flight. Its legal status, however, was not actually taken into account, as political negotiations leading to the test moratorium has been successful until present day in freezing the political crisis. This implies that the rules of the law lack the validity and logic sufficient in dictating the conduct of the States. This case shows that, in effect, it is not the rule but the politics that is to govern the status of the flight.

Drug used in hospital is allowed marketing through after pharmacological and toxicological tests using various animals and clinical test of human in developing state. But as pre-marketing clinical study take short period with relatively a few of patients and strict selection criteria of people, pediatric, geriatric. pregnancy, liver and kidney patients may be excluded. As the safety of drug isn't completely evaluated before launching. it is important to collect and evaluate drug adverse reaction newly reported by medical practitioners and pharmacists. (omitted)

Detecting environmental hazards and monitoring remote terrain are among many sensor network applications. In case of fire detection, it is significantly valuable to monitor fire-spot's shape and trend in time. Mobile ad hoc sensor nodes right round are responsible for sensoring, processing and networking packets, or even launching extinguisher. In this paper, we proposed a ring-oriented Multicast architecture based on "Fisheye State Routing" (MFSR) to organize a group of mobile ad hoc sensor nodes in a multicast way. It is familiar with traditional mesh-based multicast protocol [1] in mobile ad hoc network, trying to concentrates on efficiency and robustness simultaneously. Certain applications-based solution for hazards is proposed, quantitative results including architecture and recovery algorithms of MFSR are also investigated in this paper.

Vietnam has proceeded the gradual reform without radical political change since launching the 'Doi Moi', the comprehensive reform policy adopted in late 1986. Vietnam has been evaluated as a country to perform the economic growth for 30 years successfully, although there were economic recessions for a short time. Through looking at the process of reform, while the state economic sector and foreign-invested sector have contributed to the economic growth in the initial stage of reform, the domestic private sector and foreign-invested sector's economic roles have increased and the state sector's role has been decreased, as the reform has been proceeded. As the state's developmental role has been revealed prominently in the reform process and state's involvement into economic affairs in Vietnam, it is reasonable, in part, to categorize Vietnam as a developmental state like East Asian developmental states. However this evaluation is tentative, as it seems that Vietnamese state's industrial policies have contributed economic growth partly and remarkable economic growth has been shown in the sectors that the government has not focused. In conclusion, Vietnam has changed into a mixed country which has the characteristics of East Asian developmental state formally and the features of Southeast Asian countries which have focused more on the foreign-invested developmental strategy.

Laser Propulsion is a device that generates thrust using laser energy. Laser-driven In-Tube Accelerator (LITA) has been developed at Tohoku University. LITA is a laser propulsion system that accelerates an object not in an open air but in a tube. Experiments of vertical launching and pressure measurement on the tube wall were carried out and in order to observe the initial state of plasma and blast wave, the visualization experiment was carried out using the shadowgraph method. In this study, the time variation of pressure on the tube wall is numerically simulated solving Euler equation. In order to model the laser energy, heat source function added to the frozen flow Euler equation. Plasma size from the shadowgraph images was used for the initial condition of laser energy input. For verification of the modeling, these results were compared with the previous experimental and numerical results. From these verifications, an analysis of LITA performance will be investigated.

The responsibility to ensure the health rights of detainees, particularly their medical rights, fundamentally lies with the state in all nations. However, in the correctional facilities of the Republic of Korea, these rights are currently not adequately safeguarded. Numerous detainees express dissatisfaction with the medical services provided and show a preference for voluntary external treatment. However, barriers such as prolonged application processes for external treatment and the requirement for detainees to cover their medical expenses present significant challenges. Therefore, the National Human Rights Commission of Korea has advocated for an increased medical budget in correctional facilities and a bolstered professional medical workforce to improve the medical care of detainees. Recommendations for improvements include: (1) establishing dedicated correctional hospitals for detainees, (2) setting up specialized correctional wards, (3) collaborating with military hospitals, (4) launching mobile medical buses for diverse specialties, (5) enhancing collaboration with public and private medical institutions, (6) increasing compensation for partnering external medical institutions, (7) improving the working conditions of medical officers, (8) safeguarding the defense rights of medical staff, (9) improving the working conditions of public health doctors from the Ministry of Justice in correctional facilities, and (10) pre-assigning public health specialists and military doctors to correctional facilities. By implementing these measures, it is anticipated that the quality of medical services in the Republic of Korea's correctional facilities will improve, reducing the demand for external treatments among detainees and ensuring their health and medical rights are realistically upheld.

According to the dispostions of 1967 Space Treaty, the contracting states should assume legal obligation to assure an authorization and continuing supervision with regard to the national space activities. Any space activities have to abide by the rules of international law as well as specified obligations set by the Treaty. Among several treaty obligations, International responsibility to be bome by the state, and the liability principles are deemed as major outstanding obligations which the state should takeinto account. While nation's first launch site is to be operational in a few years, korean government should assure that its national space activities, such as launching of space object, operation of satellites, etc. should be under governmental authorization and supervision. A legislative effort would be most desirable undertaking for this regard. Especially a specific legislation needs tobe studied forwith such authorization regime so that international responsibilty and the liability as to thelaunching of space object should be under the regulatory scheme. This study focuses upon the necessity of such legislation and proposes some major items and framework for the legislation
