This study reviews how an aging society can be connected to the urban-built environment, transportation system, infrastructure, and climate change topics from the perspective of policy and innovation in science and technology. Each topic was described with the aging society that we will encounter in the near future. Based on the expected discussions, we suggested how policy and technological innovations may interact with the new emerging society. Especially, digital transformation is expected to hyper-connect the aging society beyond physical barriers where numerous policies and innovations in science and technology shed light on the elderly population. We observe, however, that this cannot be achieved only by the government sector; rather, municipal governments and local communities, as well as private sectors, all together need to prepare for the new society of the aging population. Furthermore, an ideal approach is to accommodate multidisciplinary studies that can address the policy and technological innovations simultaneously and collectively. By doing so, we can minimize the negative impacts when an aging society approaches.

Objectives: FCTC is the first international convention in public health field. Global progress report is about the implementations of the FCTC that are conducted with comparison and analysis for recent trend of tobacco control policies and convention performances on the global level. Methods: By conducting literature review related to tobacco control, expecially through reviewing Implementation of the WHO FCTC GPR(2014), this report compared and analyzed Korea's status of tobacco control based on tobacco control policy in every member state. Results: As a result of the comparison of FCTC to Korea's tobacco control policy, for the first, the most outstanding article that has been peformed continuously is Article 8, 12, 14. Secondly, the policy that has been partially renovated and reinforced is Article 6, 9, 10, 11, and for the last, the policy that has no progress and needs improvement is Article 13. Conclusions: For improvement in Korea's tobacco control policy in the future, first, betterment in policies on categories about advertisements, promotions, sponsorships on tobacco products that passed FCTC commitment period is required along with the modifications of FCTC related laws and reinforcement of the policies, and development of national core competence for an effective implementation of the convention.

The management aggravation of forests and the increase in the demand on resorts promote the urban use of forests, and the development of forests-using resorts is becoming an important political issue. Based on this understanding, this paper purports to examine the causes for the failure of the Shinrin Toshi policy (development of living space and resorts) which Japan promoted, and also examined the future direction of the development of forest resorts in Korea. As a result of the study, it was found that the Shinrin Toshi policy of Japan was promoted through the new changes of bubble economy and forest culture theory, and various strategies for the co-existence of human beings and nature were worked out. However, the policy took precedence without concrete plan production, which was found as the direct cause for the failure. The reasons for not having concrete plan production were: the target and the resort lifestyle (who will use it and what life will be developed) were not clear; the subject of the policy was restricted to state forests; and the dependence on civil capital in the promotion of the policy was too big. Therefore, in order to make the Shinrin Toshi policy successful, concrete lifestyle how the forest resort will be used and operated - needs to be set up and resources should be concretized. For this, the concrete demand on the forest resort life and the traditional community property of forest areas will have to be examined.

A steady-state controllable M/G/1 queueing model operating under the {T:Min(T,N)} policy is considered where the {T:Min(T,N)} policy is defined as the next busy period will be initiated either after T time units elapsed from the end of the previous busy period if at least one customer arrives at the system during that time period, or after T time units elapsed without a customer' arrival, the time instant when Nth customer arrives at the system or T time units elapsed with at least one customer arrives at the system whichever comes first. After deriving the necessary system characteristics including the expected number of customers in the system, the expected length of busy period and so on, the total expected cost function per unit time for the system operation is constructed to determine the optimal operating policy. To do so, the cost elements associated with such system characteristics including the customers' waiting cost in the system and the server's removal and activating cost are defined. Then, procedures to determine the optimal values of the decision variables included in the operating policy are provided based on minimizing the total expected cost function per unit time to operate the queueing system under considerations.

Development of research methodology and the construction of innovative management systems in accordance with the objectives of the ongoing study is related to the innovations in the system of state management technologies that are considered as intangible innovations embodied in the rules, organizational structures and management processes aimed at the qualitative improvement of the functioning of public authorities. This innovation - is a process that leads to a new quality of growth, efficiency jump.

This paper presents a model for determining the optimal number of general repairs and supplementary input cost limit rate in addition to minimal repair cost rate to implement preventive maintenance. The basic concept parallels the periodic replacement model with minimal repair at failure introduced by Barlow and Hunter(1960) and Park(1979), only difference being the replacement signalled by the number of previous general repairs performed on the system. A general repair brings the state of the system to a certain better state than before repaired. Numerical examples are provided.

A repair process of a system consisting of both perfect repairs and minimal repairs is introduced. The type of repair, when the system fails, is determined by an embedded two state Markov chain. We study several stochastic properties of the process including the preservation of ageing properties and the monotonicities of the time between successive repairs. After assigning repair costs to the process, we also show that an optimal repair policy uniquely exists, if the underlying life distribution of the system has DMRL.

In this study, an efficient algorithm is developed to compute steady state probabilities for the following M$_{x}$G/1 server vacation system under control-operating poligy: At the end of a busy period, the server takes a sequence of vacations, each for a random amount of time. At the end of each vacation, he inspects the length of the queue. If the queue length at this time is equal to or greater than a prespecified threshold value r, he begins to serve the queue until it is empty.y.

Reinforcement Learning (RL) is one of machine learning methods and an RL agent autonomously learns the action selection policy by interactions with its environment. At the beginning of RL research, it was limited to problems in environments assumed to be Markovian Decision Process (MDP). However in practical problems, the agent suffers from the incomplete perception, i.e., the agent observes the state of the environments, but these observations include incomplete information of the state. This problem is formally modeled by Partially Observable MDP (POMDP). One of the possible approaches to POMDPS is to use historical nformation to estimate states. The problem of these approaches is how t..

In this study, two stage transfer line with limited repair capability is modeled to formulate optimal dynamic repair priority policy. The method of Markov Chains is used to analyze the analytical model of this line. An efficient algorithm is developed, utilizing the block tridiagonal structure of the transition probability matrix, to obtain the steady state probabilities and system performance measures, such as the steady state production rate of the line and the average in-process inventory in the interstage buffer.
