With the evolution of containerization and globalization of supply chains, aspects of port functions have made the transition from the sea to the inland region that forms the dry port. To explore the relationship between dry ports and regional economic development, this study uses a gravity model and forecast model to analyze 1,040 observations in 104 cities (22 dry port cities) along the Yangtze River Economic Belt (YREB) from 2008 to 2017. The model includes economic variables, logistics variables, foreign relations variables, and human capital variables. It was found that the dry port is positively correlated with trade volume. Compared with a city without a dry port, the trade volume of a city with a dry port will increase 0.099 times. It can be concluded that a dry port is crucial for the economic development of the YREB. It was also found that per capita GDP as an economic variable, road area and rail number as logistics variables, and foreign relation variables are positively correlated with trade volume, while the human capital variable has no significant effect on trade volume. In addition, governmental policy implications are addressed from the aspects of dry port and industry cluster caused by foreign investment.

Social credit rating in China (SCRC) has been criticized as "dystopian" and "Orwellian," an attempt by the Communist Party to hold onto power by exerting ever greater control over its citizens. To explain such measures, value differences are often invoked, that Chinese value stability and cooperation over privacy and freedom. However, these explanations are oversimplifications that result in ethical impasses. This article argues social credit rating should be understood in terms of the commonly human problem of large-scale cooperation. To do so, this paper relies on a cultural evolutionary framework and is an exercise in interpretive pros hen ethical pluralism, attempting to understand how apparently irresolvable cultural differences stem from common human concerns. Wholesale condemnation of SCRC fails to acknowledge the serious, intractable nature of problems resulting from a lack of trust in China. They take for granted the existence of institutions ensuring largescale, anonymous cooperation characteristic of - but somewhat unique to - Western Educated Industrialized Rich and Democratic (WEIRD) cultures. Because of its history and rapid development, China lacks the institutions necessary to ensure such cooperation, and because of anti-social punishment, social credit rating might be one of the few ways to ensure cooperation at this scale. The point is not to defend social credit rating in general, but to raise the possibility of its defense in China and show one way this would be done.

The Tactile Internet technology is considered as the evolution of the internet of things. It will enable real time applications in all fields like remote surgery. It requires extra low latency which must not exceed 1ms, high availability, reliability and strong security system. Since it appearance in 2014, tremendous efforts have been made to ensure authentication between sensors, actuators and servers to secure many applications such as remote surgery. This human to machine relationship is very critical due to its dependence of the human live, the communication between the surgeon who performs the remote surgery and the robot arms, as a tactile internet actor, should be fully and end to end protected during the surgery. Thus, a secure mutual user authentication framework has to be implemented in order to ensure security without influencing latency. The existing methods of authentication require server to stock and exchange data between the tactile internet entities, which does not only make the proposed systems vulnerables to the SPOF (Single Point of Failure), but also impact negatively on the latency time. To address these issues, we propose a lightweight authentication protocol for remote surgery in a Tactile Internet environment, which is composed of a decentralized blockchain and physically unclonable functions. Finally, performances evaluation illustrate that our proposed solution ensures security, latency and reliability.

A public health concern emerging from a zoonotic disease. Monkeypox is caused by the orthopoxvirus specie Monkeypox virus (MPXV). Monkeypox was identified as the most common orthopoxvirus infection in humans following the eradication of smallpox. Monkeypox has a similar clinical presentation to smallpox. The MPXV is now considered a high-threat pathogen that causes a serious public-health problem. The continuous spread of Monkeypox virus from West Africa to all other places around the world throughout 2018 to 2022, have raised concerns that MPXV could have emerged to acquire the immunological and ecological niche vacated by smallpox virus. This review highlights the current knowledge about Monkeypox evolution, infection biology, and epidemiology around the world since from 1970 to 2022, with a focus on the human, viral, and cellular factors that influence virus emergence, infection, spread, and maintenance in nature. This paper also discusses the current therapeutic options for Monkeypox treatment and control. Under the right conditions, with limited smallpox vaccination and very little orthopoxvirus immunity in some areas of the world, MPXV could become a more efficient human pathogen. Finally, the review identified knowledge gaps, particularly in terms of identifying a definitive reservoir host for monkeypox and proposes future research endeavors to address the unanswered questions.

SMRT(Seoul Metropolitan Rapid Transit Corporation) changed PC-oriented office system to Smart-Phone oriented mobile office system(STnF: SMRT Talk & Flash), and provided smart phone to all staffs. STnF make it possible not only voice communication between staff, but also to input and inquiry all kind of information related to work(ex: Facility maintenance, Rolling Stock management, office management, Finance, human resource etc.) based on smart phone. STnF conquers the limitation of time and space. All staffs can commute to the site directly to reduce moving time and to share information between staffs, so SMRT improve speed and reliability of work by making a quick decision and action on the spot. After introduction of STnF, within 1 year, the equipment failure ratio fell to 47%. Mobile office system reduced and level-off the step of approval. so enhanced civil customer service. Quantification and scientific movement of work make it fast evolution and development. These business improvement make it possible to put more outstanding manpower on new business and R&D project, and this contributes to company's management effectiveness.

Interactive space became one of the modern contemporary society design paradigms. For elevating the interactive effect, we need Interactive design development which uses the influential factors on the interactivity. Digital technology is resulted in a change to a society as well as to the life of human and its way of communication. This study is inquiry into the relations and the common characteristics between ecological architecture space and eco-centric environmental philosophy by making a comparative research. This aims to examine type of spatial contexts for performed through literature research for theory by interactive space and case studies for ecological construction elements to design. And the range of case study is limited to interaction space in addition of interactive elements and user interface. And analysis conclusion is show the many type. Five principles that draw at ecological design conceptualization process, whole unity, variety of organic at ecological design conceptualization process, circularity, homeostasis, allness, biological evolution, diversity have involved with concept that presents in ecological esthetics and organic property of ecology-system.

Upbringing requires an active intervention in the process of children growing up. Convergence in technology and media makes it possible to augment nurturing by making blended infrastructures with new digital resources available in learning environments at schools. A game-based provision of educationally-valuable content within a collective, virtual environment combined with an analysis of events in the game after it has been played (blended nurture environment) may help to better communicate human values especially where old-fashioned discussion methods fail or do not fulfill the promise of effective, educational institution-based methods of bringing up. This is where life sciences, psychology, media, pedagogy and technology (need to) converge.

The evolution of bipedal robots was the foundation stone for development of Humanoid robots. The highly complex and non-linear dynamic of human walking made it very difficult for researchers to simulate the gait patterns under different conditions. Simple controllers were developed initially using basic mechanics like Linear Inverted Pendulum (LIP) model and later on advanced into complex control systems with dynamic stability with the help of high accuracy feedback systems and efficient real-time optimization algorithms. This paper illustrates a number of significant mathematical models and controllers developed so far in the field of bipeds and humanoids. The key facts and ideas are extracted and categorized in order to describe it in a comprehensible structure.

Many human inventions were inspired by nature. The artificial neural network is one example. Another example is Genetic Algorithms(GA). GAs search by simulating evolution, starting from an initial set of solutions or hypotheses, and generating successive "generations" of solutions. This particular branch of AI was inspired by the way living things evolved into more successful organisms in nature. To simulate the process of GA in a computer, we must simulate many times according to varying many GA parameters. This paper describes the implementation of Java Package for efficient applications on Genetic Algorithms, called "JavaGA". The JavaGA used as a application program as well as applet provides graphical user interface of assigning major GA parameters.

In human chromosome, a short sequence of DNA has been repeated a number of times. These repeats are called variable number of tandem repeat(VNTR) or short tandem repeat(STR) which has short repeat core. VNTR and STR are used in the field of forensic science, evolution, and anthropology. In this work, we examined allele frequencies of 3 VNTR(YNZ22, NeuR, D21S11) and one STR(Humth01) in a Korean population sample by polymerase chain reaction(PCR) followed by high-resolution polyacrylamide gelelectrophoresis(PAGE) with silver staining. Subsequently, the polymorphism information content(PIC) was calculated : the highest PIC was observed for the NeuR locus(0.95680) and lowest for the Humth01 locus(0.75809).
