In this paper there is an overview of some standards and security models which are implemented in such an IP-based and heterogeneous networks and we also present some security models in an open environment and finally we obtain that as a result of the nature of 4G networks there are still more security holes and open issues for expert to notice. Our survey shows that a number of new security threats to cause unexpected service interruption and disclosure of information will be possible in 4G due mainly to the fact that 4G is an IP-based, heterogeneous network. Other than that, it tells about the security issues and vulnerabilities present in the above 4G standards are discussed. Finally, we point to potential areas for future vulnerabilities and evaluate areas in 4G security which warrant attention and future work by the research and advanced technology industry.

In Korea, there is great lack in jet lease agreements compared to many other countries. Due to such scarcity in numbers of jet lease agreements, problems have never truly surfaced and legal foundation dealing with such issues have not yet been formulated. However, as the globalization is making the world smaller and smaller, the demand for jets will grow. As the Korean aviation industry is expanding tremendously, although very preliminary at this time, the interest and actual execution on private jet lease agreements will grow. The prediction of increase in the private jet ownership is causing the lease industry to be nervous and may require particular preparatory foundation works. Particularly, legal analysis and detailed review maybe necessary to set a precedent with will serve as the grounded rule in the future. It is notable that Vietnam, a country which is believed have a less developed aviation industry than Korea, had already established a specialized jet leasing company, VALC in 2007. Also, when leasing an airplane from a foreign financial institution, it is possible to obtain a government issued guarantee. Therefore, it is urgent for Korea to prepare the legal foundation for the future demands in aviation leasing, as well as private jet leases which in turn would promote national wealth and further develop the financial industry.

아직까지 범죄학은 학문적 정체성을 제대로 찾지 못하고 있다. 그 주된 원인은 범죄학연구가 사회학적 접근방법에만 주로 의존했기 때문이다. 따라서 범죄학에는 생물학, 심리학, 그리고 사회학 등 여러 학문분야들을 모두 아우르는 간학문적 접근방법(interdisciplinary)이 동원되어야 한다. 그러나 이것은 생물학이나 심리학적 연구가 사회학적 접근방법을 대신하는 것을 의미하는 것은 아니다. 다만 다양한 분야의 학자들이 범죄를 연구하여 하나의 체계화 된 일반이론으로 정립될 수 있도록 노력해야 한다는 것이다. 본 연구는 그 이외에도 범죄학이 과학이 되기 위한 조건과 기타 앞으로 범죄학이 나아가야할 방향에 대해 논의하였다.

As industrialization and urbanization accelerate, environmental issues have moved from local concerns to global issues. Among them, air pollution is the most important issue. Modern people spend more than 88% of their day indoors, but the concentration of fine dust and pollutants flowing indoors is increasing. The indoor environment has its own complexity, and various substances used indoors, such as building materials, furniture, electronics, and cleaning agents, emit chemical substances and cause various diseases. Therefore, when selecting building materials and interior finishing materials, the pollutant emission and adsorption capacity must be greatly considered. These considerations will ensure the construction of a sustainable future environment and a healthy life within that environment. Therefore, in order to reduce the generation of indoor air pollutants, this study aims to examine the fine dust adsorption properties of cement hardening materials using sepiolite, which has a porous structure and high absorption power among clay minerals. As a result of the experiment, it was found that the concentration of fine dust decreased as the addition rate of sepiolite increased. It is believed that the fine dust concentration was reduced due to the high porosity due to the microfibrous structure and large specific surface area of sepiolite, which has a porous structure among clay minerals. It is believed that these experimental results can be used as basic research for future use of sepiolite as a construction material.

Purpose: This study aims to evaluate the barrier-free environment at Fukui University's Bunkyo Campus, focusing on the mobility of students using manual wheelchairs. Methods: Data were collected on architectural plans, barrier-free facilities, and class schedules at Fukui University's Bunkyo Campus. Measurements included step heights, slopes, and the accessibility of classroom furniture for manual wheelchairs. Mobility was assessed by timing the movement between 19 classrooms used in the second semester of 2022 during breaks and summer vacation. Results: This study highlights that while Fukui University's Bunkyo Campus has some barrier-free buildings, significant improvements are needed. Issues include inadequate elevators, hand operated doors, and multi-purpose restrooms, as well as inefficient classroom's furniture layouts for wheelchair users. To enhance accessibility, future efforts should focus on reducing elevator wait times, automating doors, and optimizing classroom designs. Implications: The study indicates that Fukui University's Bunkyo Campus needs significant improvements in barrier-free accessibility. It provides foundational data for future detailed planning and implementation. Enhanced campus accessibility and better classroom designs are crucial for equal learning environments. Similar issues may exist at other Japanese universities, warranting broader investigation.

Nowadays, the public as well as science educators pays much attention to the fourth industrial revolution and wonders what will happen to the societies in the future. Thus, this study aimed at predicting the education environment which will be brought from the fourth industrial revolution, and suggesting the solutions or tasks to be investigated in science education. Through the literature review, this study categorized the major changes of future society into a wild fluctuation of job market, the shift from possession-based economy to sharing economy, post-urbanized and distributed system, and the crisis of dehumanization. According to the four major changes, this study predicted the future environment that will occur to the educational system. First, the students should the competences necessary for the future and the school curriculum will be changed in terms of width and depth. Second, sharing economy may bring about the open platform similar to MOOC (Massive Open Online Course) or TED. Third, the manifestation of artificial intelligence in education will enable the individual and paced learning, and thanks to the change, the concept of distributed cognition will be more focused in education research. Fourth, the collaborative learning and character education should be more stressed to resist the dehumanization. This study suggests relevant tasks and issues that should be tackled for the successful change in primary and secondary schools.

The purpose of this study was to investigate current status of 19 general hospitals which performed the hospital social responsibility (HSR) to global health issues. The survey focused on the global healthcare supporting system & activity (including the administration, information, materials, finance, and human resources, et al.), and the government's policy in Korea. Based on the analysis of survey data, the main global health issues of general hospitals were activities of overseas volunteers (56%) and aids of the developing countries (19%). Also, general hospitals have mainly supported into eastern Asia (49%). And then, the most important goal of general hospitals related these activities kept the founding principle of a hospital for global health issues (53%). The second ranking was the social responsibility (32%) and the interchange between Korean and foreign hospitals (32%). There were many differences between general hospitals about the global healthcare supporting system & activities for HSR to global health issues. In conclusion, we suggest that most of general hospitals in Korea would be gotten prior setting the global issues for unmet-need of the developing countries around the world in the near future. This study also served as the effective way by partnership on global health issues of general hospitals for recognizing the HSR as hospital governance.

Although there have been many endeavors aimed at the standardization and globalization of Korean medicine over a long period of time, the access to information on Oriental medical classics has been relatively poor due to the lack of appropriate translation methodology and standard terminology. In order to overcome existing barriers, continuous effort towards precise translation adopting a standard terminology should be maintained. As a part of this procedure, we planned to publish a part of "Classic of difficult issues(難經)" in three sections, and the first two studies have already been published. Based on the methodology and approaches of previous studies, this third study aims to translate parts of "Classic of difficult issues(難經)" into English, beginning with "The Sixteenth Question", and adopting "WHO-IST" terminology. The outcomes of this study are presented as follows: First, based on the result of existing translation studies and the outcome of "WHO-IST", English translation of "Classic of difficult issues(難經)" from "the Sixteenth Question" to "The Twenty-second Question" is offered, hoping to set a model of translation study which can be communicated universally. Second, in order to pave the way for future success in establishing translation studies, it is natural to verify the effectiveness and practicality of standard terminologies including the outcome of "WHO-IST". Continuous translation studies will be required in order to obtain constant feedback and adopt more suitable guidelines during the standardization process. Taking this into consideration, further translation studies of Oriental medical classics including "Classic of difficult issues(難經)" should be continued.
