Abstract
Purpose
The purpose of this paper is to propose a high‐mobility in‐pipe robot platform and its navigation strategy for navigating in T‐branch pipes efficiently.
Design/methodology/approach
For high mobility, this robot is developed based on inchworm locomotion. An extensor mechanism with flexible links and clamper mechanisms enable the robot to conduct both steering and inchworm locomotion. The locomotion of the robot is modeled based on a pseudo‐rigid‐body model. From the developed model, this paper introduces a navigation strategy based on defining relay points and generating a path from a main pipe to a T‐branch pipe.
Findings
With this navigation strategy, the robot can avoid collisions and enter T‐branch pipes effectively. The path generation algorithm is verified by experiment. In addition, both the navigation strategy and mobility of the robot are demonstrated by experiments conducted in a commercial pipe configuration.
Originality/value
This paper describes the mechanism of an inchworm‐type in‐pipe robot that is able to steer and adapt to pipe diameter changes. This paper also describes navigation strategy that enables a robot to avoid collisions and enter T‐branch pipes effectively. This research will help the construction of a fully autonomous in‐pipe robot that can navigate through various types of pipes.

Abstract
Purpose
The purpose of this paper is to empirically investigate the negative casual relationships between organizational security factors (security systems, security education, and security visibility) and individual non-compliance causes (work impediment, security system anxiety, and non-compliance behaviors of peers), which have negative influences on compliance intention.
Design/methodology/approach
Based on literature review, the authors propose a research model together with hypotheses. The survey questionnaires were developed to collect data, which then validated the measurement model. The authors collected 415 responses from employees at manufacturing and service firms that had already implemented security policies. The hypothesized relationships were tested using the structural equation model approach with AMOS 18.0.
Findings
Survey results validate that work impediment, security system anxiety, and non-compliance peer behaviors are the causes of employee non-compliance. In addition, the authors found that security systems, security education, and security visibility decrease instances of non-compliance.
Research limitations/implications
Organizations should establish a mixture of security investment in their systems, education, and visibility in order to effectively reduce employees’ non-compliance. In addition, organizations should recognize the importance of minimizing the particular causes of employees’ non-compliance to positively increase intentions to comply with information security.
Originality/value
An important issue in information security management is employee compliance. Understanding the reasons behind employees’ non-compliance is a critical issue. This paper investigates empirically why employees do not comply, and how organizations can induce employees to comply by a mixture of investments in security systems, education, and visibility.

Abstract
Purpose
Organizations invest in information security (IS) technology to be more competitive; however, implementing IS measures creates environmental conditions, such as overload uncertainty, and complexity, which can cause employees technostress, eventually resulting in poor security performance. This study seeks to contribute to the intersection of research on regulatory focus (promotion and prevention) as a type of individual personality traits, technostress, and IS.
Design/methodology/approach
A survey questionnaire was developed, collecting 346 responses from various organizations, which were analyzed using the structural equation model approach with AMOS 22.0 to test the proposed hypotheses.
Findings
The results indicate support for both the direct and moderating effects of security technostress inhibitors. Moreover, a negative relationship exists between promotion-focused employees and facilitators of security technostress, which negatively affects strains (organizational commitment and compliance intention).
Practical implications
Organizations should develop various programs and establish a highly IS-aware environment to strengthen employees' behavior regarding IS. Furthermore, organizations should consider employees' focus types when engaging in efforts to minimize security technostress, as lowering technostress results in positive outcomes.
Originality/value
IS management at the organizational level is directly related to employees' compliance with security rather than being a technical issue. Using the transaction theory perspective, this study seeks to enhance current research on employees' behavior, particularly focusing on the effect of individuals' personality types on IS. Moreover, this study theorizes the role of security technostress inhibitors for understanding employees' IS behaviors.

Abstract
There have always been North Korea Risks in South Korea stock market since its opening. Some studies have concluded that it does not have a substantial impact on South Korea’s economy due to chronic geopolitical risks, while others have argued it has had an impact. However, in light of the Efficient Market Hypothesis (EMH) it can be argued that both opinions view that information about North Korea Risks affects stock markets and that stock prices react to it. This study analyzed the effects of North Korea Risks on South Korea’s stock market using event study methodology empirically, and it tested the semi-strong EMH-a market in which prices always fully reflect available information. The research results are following:
First of all, North Korea Risks have an impact on South Korea’s stock market and the data was statistically significant. In particular, stock market already reflected information about the forewarned events like nuclear test. However, market also responded to information about sudden events such as the impact of Kim Jung-il’s death on the South-North economic cooperation stock. Portfolio analysis demonstrated that small capital stocks were affected more than large caps. These results cannot reject the EMH.
Also, estimates of market model and that of Fama-French three-factor model did not show a statistically significant difference in different verification. There was no statistically significant difference between growth and value stock in large caps portfolio either. However, there was a statistically significant difference between defense stock and South-North economic cooperation stock, small caps and big caps, and weighted average and simple average.
The significance of this study lies in that it conducted the event study by variety estimation model with objective standards for selecting events when measuring the effect of North Korea Risks.

Abstract
Purpose
The purpose of this paper is to address the overarching question, which was whether the incentives programmes formulated for the community have been found to be suitable to the aspirations and needs of the local residents.
Design/methodology/approach
This study has resulted from the authors’ experience through conducting a survey with the local residents in three locations, namely the Bukchon Hanok Village located at Seoul metropolitan city; the Hahoe Village, Angdong and the Yangdong Village, Gyeongju; both the latter are located towards the west of the Korean peninsula in the Gyeongbuk-do Province. This study has hopefully tried to analyse the residents’ perception of the effectiveness of the current incentives policy by using the Bennett’s programme evaluation method.
Findings
Results show that there was a divergent direction between the current incentives policy and the local aspirations between sites. In most cases, the cultural heritage conservation has been found to be a catalyst to fulfil a heritage tourism advantage rather than to cater to the local community needs.
Originality/value
The paper is the first insightful study of the historic villages which attempts to draw out the importance of the effectiveness of the incentives programme in guiding the conservation efforts for the local economic development.

Abstract
Purpose
The purpose of this paper is to clarify the relationship between subjective experience of an event, motivational style for participating and satisfaction afterwards. It proposes that subjective experience of positive affect acts as a mediator between motivation and satisfaction.
Design/methodology/approach
The paper opted for a quantitative survey among 285 respondents asking about their motivation to participate in celebrating Queen's Day, a Dutch national event around the birthday of the Queen Mother. Their satisfaction levels and subjective experience of the event were collected after the event. The (mediation) hypotheses were tested through a series of regression analyses.
Findings
The paper provides empirical insights about how subjective experience mediates the effect between motivational style and satisfaction.
Originality/value
This paper fulfils an identified need to study the effects of subjective experience in events.
