Abstract
In this paper, we discussed relations between drivers' cognition and the dynamics of traffic conditions. When we take into account drivers' cognition, many types of psychological impedance to behavioral change could be accounted for, including cognitive conservatism and habitual decision making. Based on psychological theories with respect to these impedance to behavioral change, we elucidated the process of changes in traffic conditions that might be induced by changes in road-network structure. As a result of the discussion, we concluded that traffic conditions are unlikely change as much as predicted by theories that assume a simple, and sometimes unique, relation between a traffic condition and a road-network structure, e.g., theories that assume user equilibrium.

Abstract
Purpose: This chapter aims to lay out the issues regarding the world of digital currencies, private and central bank digital currency (CBDC). In that connection, the authors want to, as much as possible, systematically present the terminology, examples of various digital currencies and the technology behind that phenomenon. The chapter also highlights the occurrence of CBDC and the possible implications of its introduction to day-to-day commercial banking practice, possibly taking the payment systems and transactions alternation, balance sheet and profits’ issues into consideration.
Need for the study: Digital currencies already have and are also soon going to have an enormous impact on society as such, where payments for everyday goods and services are taken on a whole new platform and level, in the sense of how the payments are made and payment systems are constructed, as also in the sense of quantity, as the number and sum-wise payments carried out via such platforms are growing.
Methodology: A triangulation method, a mixed qualitative methodological approach was implemented, so the research offers a synthesis of previously published contributions in this field, followed by deductive and inductive reasoning interconnected with descriptive and comparative analyses.
Findings: As digital currency already have a vast impact on payment systems and modes of payment, the CBDC, an imperative of today and not the matter of the future, will have implications for commercial banks, probably in the field of lowering banks’ commissions, no big customer data-selling ability, accumulating the deposits and deposit policies and credit policies due to higher funding costs for banks. There is an interwovenness among the central bank activities, bank customer’s behaviour and commercial bank activities. Therefore, the change of payment and spending behaviour of customers because of central banks’ introducing novelties will also have consequences for the banking industry.
Practical implications: The choice to handle cash or digital currency will be obsolete, and an individual’s or a firm’s financial knowledge must be upgraded in the field of new money using angles. The issue of digital currencies and CBDCs are no longer a matter of choice but are becoming a new reality. Therefore, it is necessary for the common public, economy and banking system, especially now carrying out most of payments and transfers of money, to study this field and foresee the possible consequences and risks emerging.

Abstract
Purpose
Although individual exploration activities have been shown to promote organizational change and innovation, few studies have clarified the factors that quantitatively promote such aspects. This study aims to examine how individual exploration activities are facilitated by goal orientation and individual unlearning.
Design/methodology/approach
The data are analyzed from 1,474 employees in various jobs in a variety of organizations in Japan. This study uses structural equation modeling to test the research model.
Findings
The results of this study indicate three findings. First, unlearning is effective in promoting individual exploration activities. Second, goal orientation has not only a direct effect on individual exploration activities but also a significant indirect effect on such activities through unlearning. Third, performance goal orientation has an inhibitory effect on individual exploration activities.
Practical implications
Managers should encourage team members’ exploration activities by setting learning goals for members and providing opportunities for members to unlearn the outdated knowledge or skills they are familiar with and learn new ones.
Originality/value
These findings contribute to the existing literature by demonstrating that learning goal orientation and unlearning play important roles in promoting individual exploration activities.

This paper aims to observe the possible relationship between skin color, sun exposure level, UV protection and food intake and serum levels of 25(OH) D in Japanese older adults.
Abstract
Purpose
This paper aims to observe the possible relationship between skin color, sun exposure level, UV protection and food intake and serum levels of 25(OH) D in Japanese older adults.
Design/methodology/approach
Elderly (n = 131; 65-93 years old), followed by the Tokyo Metropolitan Institute of Gerontology in the Kusatsu (36°N) received a self-applicable questionnaire about the quantity and quality of the daily sun exposure and behavior to avoid the sun. A color analyzer measured each red (R), green (G) and blue (B) component of skin color, and dietary vitamin D was estimated by food frequency questionnaire. Serum 25(OH) D levels were collected and categorized as sufficiency (>30 ng/mL), insufficiency (between 20 and 30 ng/mL) and deficiency (<20 ng/mL).
Findings
High proportion of participants had insufficiency (53 per cent) and deficiency (25 per cent) levels of 25(OH) D. Insufficiency levels were more prevalent in women (57 per cent, p = 0.048) and in participants that use gloves (49 per cent, p = 0.054) and sunscreen on face (76 per cent, p = 0.003) as a sun protection way. Participants with sufficiency levels of 25(OH) D presented lower values of R (p = 0.067), G (p = 0. 007) and B (p = 0.001) of skin color (what is meaning darker skin) and a higher fish intake (12 times per week).
Research limitations/implications
The study is a cross-sectional design and brings a potential for measurement error in the recorded subjective variables. There is a memory bias in self-reported sun exposure and food consumption; however, in the multivariate analysis, it was demonstrated a significant association. Second, although the authors have sought to evaluate a number of variables that could affect the skin’s ability to synthesize vitamin D, there are many other factors that may affect this ability that could not be accounted for. Another limitation was the assessment of self-reported ultraviolet exposure data rather than direct measurement of exposure.
Practical implications
It was also concluded that darker skin color (a surrogate of longer-term sun exposure) participants had a lower prevalence of vitamin D insufficiency in this ethnic homogeneous population. When accessing patients’ skin color, the clinician must account for his or her ethnicity.
Social implications
Governments should regulate supplementation or food fortification with vitamin D, with special focus in countries with geographical location of insufficient solar radiation for skin synthesis of this vitamin. With this, it becomes a priority that a safe sun exposure ensures the sufficient serum levels of 25 (OH) D without the use of supplements.
Originality/value
This report was the first to analyze skin color components associated to vitamin D levels, finding that blue and green colors were significant. The clinical implication of this find is yet to understand. It was also concluded that darker skin color (a surrogate of longer-term sun exposure) participants had a lower prevalence of vitamin D insufficiency in this ethnic homogeneous population. When accessing patients’ skin color, the clinician must account for his or her ethnicity.

Abstract
Purpose
The purpose of this study is to address the limitations of traditional methods for managing intellectual property rights (IPRs) by proposing a blockchain-based solution. By leveraging blockchain technology and smart contracts, the aim is to create a comprehensive ecosystem that offers advantages such as reduced transaction costs, improved transparency, enhanced security and increased liquidity levels for IP assets.
Design/methodology/approach
This paper proposes using blockchain technology to manage intellectual property rights (IPRs) through a smart contract-based ecosystem. It outlines the use of non-fungible tokens (NFTs) on the blockchain to represent IPRs, with smart contracts automating interactions and encoding rules for various processes such as applications, licensing, transfers and royalty distribution. Governance mechanisms, such as decentralized autonomous organizations (DAOs), are employed to allow stakeholders to propose and vote on contract changes, ensuring adaptability. This approach aims to streamline IPR workflows, reduce transaction costs, improve transparency and enhance security.
Findings
The findings of this study suggest that implementing a blockchain-based ecosystem for managing intellectual property rights (IPRs) can lead to various benefits. These include reduced transaction costs, improved transparency, enhanced security, increased liquidity levels for IP assets and streamlined automated processes. The use of non-fungible tokens (NFTs) on the blockchain allows for detailed management, valuation and trading of IPRs. Furthermore, simulation results demonstrate the robustness and efficiency of our proposed ecosystem, outperforming traditional IP management systems in terms of transaction speed and cost-effectiveness. These simulations highlight the practical viability of integrating blockchain technology into IP management workflows.
Practical implications
The practical implications of adopting this blockchain-based ecosystem for managing intellectual property rights (IPRs) are significant. By streamlining processes, reducing transaction costs and improving transparency and security, organizations can expedite the protection and commercialization of their IP assets. Additionally, the increased liquidity levels and accessibility of IP assets to investors and financiers can spur innovation and economic growth.
Originality/value
This paper contributes to the field by proposing a novel approach to managing intellectual property rights (IPRs) using blockchain technology and smart contracts. By leveraging non-fungible tokens (NFTs) on the blockchain, the proposed ecosystem offers a more efficient and transparent way of managing IPRs, reducing reliance on costly and opaque traditional methods. The potential benefits include improved efficiency, transparency, security and collaboration in the management and commercialization of IPRs.
