This study intended to examine how customers of self-service technology of airlines perceive and adopt the technology, and how such perceptions affect their willingness to use it. The findings of analysis are as follows. First of all, self-efficacy, a personal characteristics variable, has significant effects on both perceived usefulness and ease of use (H1). Second, though personal innovation which accepts new information technology more positively and challenge to use it before others has significant effect on perceived usefulness (H 2-1), it does not have significant effect on ease of use (H 2-2). Third, perceived ease of use has effect on perceived usefulness. Forth, both perceived usefulness and ease of use have positive effects on willingness to use.

This essay is a critical study of the three models of practical theology that emerged in the second half of the 20th century: the critical correlational model (Sherrill, Browning), the hermeneutical model (Groome, Gerkin), and the faith community formation model (Westerhoff, Campbell). This essay first explores the central ideas of practical theologians who adhere to each of the three models and focuses on Christian education, pastoral counseling, and homiletics. This essay then critically evaluates the three models in accordance to the following four themes: how practical theology has 1) responded to the challenges of postmodernity, 2) engaged in dialogue with different types of theology, 3) participated in interdisciplinary dialogue, and 4) understood Christian practice. In conclusion, this essay suggests that the essential tasks of contemporary Christian education as practical theology include: 1) providing an active response to many challenges of postmodern, postsecular, postdigital, and posthuman era, 2) engaging in interactive dialogue with diverse forms of theology, and 3) facilitating interdisciplinary dialogue based on transversal rationality, and 4) establishing of the concept of Christian practice at the individual, ecclesial, social, public, ecological, and digital levels.

The purpose of this study is to define the process of leading to self-realization and social solidarity through the process of contents planning, production, and distribution as Contents Activism, and to categorize specific execution steps. Based on this, we try to analyze concrete cases to find out the social meaning and effect of the practice of Contents Activism. As for the research method, after examining the differences between traditional activism and Contents Activism through a review of previous studies, the implementation process of Contents Activism was categorized into 7 steps. By applying this model, this study analyzed two cases of Contents Activism. The first case is the 100 laps challenge in the backyard planned by an elderly man ahead of his 100th birthday in early 2020, when the fear of COVID-19 spread. Sir Tom Moore, who lives in the UK, challenged to walk 100 laps in the backyard to help medical staff from the National Health Service as COVID-19 infections and deaths increased due to a lack of protective equipment. His challenge, which is difficult to walk without assistive devices due to cancer surgery and fall aftereffects, drew sympathy and participation from many people, leading to global solidarity. The second case analyzes the case of 'The Unfreedom of Expression, Afterwards' by Kim Seo-kyung and Kim Woon-seong, who were invited to the 2019 Aichi Triennale special exhibition in Japan. The 'Unfreedom of Expression, After' exhibition was a project to display the Statue of Peace and the lives of comfort women in the Japanese military, but it was withdrawn after three days of war due to threats and attacks from the far-right forces. Overseas artists who heard this news resisted the Triennale's decision, took and shared photos in the same pose as the Statue of Peace on social media such as Twitter and Instagram, empathizing with the historical significance of the Statue of Peace. Activism, which began with artists, has expanded through social media to the homes, workplaces, and streets of ordinary citizens living in various regions. The two cases can be said to be Contents Activism that led to social practice while solidifying and communicating with someone through contents.

Nowadays companies are required to achieve social goals beyond maximizing shareholder profits. Accordingly, it is important to pursue both the economic and social goals of a company at the same time. Thus the importance of hybrid organizations is increasing theoretically and practically. In particular, since hybrid organizations essentially have the complexity of pursuing both economic and social purposes, the institutional demands of various stakeholders surrounding hybrid organizations are also conflicting. Several previous studies have considered how hybrid organizations respond to these conflicting institutional demands, but most studies are limited to studying at a specific point in time. As a result, there was a limit to analyzing the dynamics in response to conflicting institutional demands as the hybrid organization expanded its business. This study predicted that the hybrid organization would take selective coupling with conflicting institutional demands and that the process of responding to institutional demands would change according to the organization's growth. In this study, we had a case study about Noul and Enuma, social ventures that operate relatively advanced business models with outstanding results in innovation and technology. As a result, social ventures show a selective coupling for conflicting institutional demands, and the selective coupling process changes as their business model are advanced. Specifically, in the early stages of the business, it appears to respond to economic and social demands at the same time with a single business model. When the business is advanced, two or more business models are operated, some of which respond to economic needs and some of which respond to social needs. In the early stages of business, social ventures respond to economic and social demands with a single business model to gain legitimacy and survive in the institutional demands. But when they enter the business growth period, they try to separate business models which respond to economic and social values because they pursue sustainable growth and challenge large-scale missions. Overall, this study attempted to contribute to an in-depth understanding of hybrid organizations by identifying that the method of responding to conflicting institutional demands varies depending on the growth process of social ventures.

In developing countries, the establishment of maritime colleges and the training of excellent merchant marine officers can greatly impact on the growth of the marine industry in a given country. The project to establish the Kenya Maritime College ('KMC') has been driven by the Kenyan government, which has been challenged by the growth of the marine industry in Korea. This study aims to the development of curriculum for the navigation science department of the KMC. To do this, firstly the Kenyan environments was surveyed. Then, IMO maritime education requirements, IMO model courses and curriculums from the navigation science departments of major maritime universities around the world were reviewed. Lastly, based on these surveys and reviews, curriculum for the navigation science department of the KMC was developed. This curriculum is comprised of an educational course that requires a total of 5 years of study, including 1 year of on-board training and a total of 200 credit hours (20 credit hours per semester). Although this curriculum has been developed to fit the environments of Kenya, it is expected to offer a point of reference for similar studies in other countries with the goal of standardizing maritime education internationally.

In the almost application parts, GNSS being used the primary navigation system on world-widely. However, some of nations attempt or deliberate to enhance current Loran system, as a backup to satellite navigation system because of the vulnerability to the disturbance signal. Loran interests in supplemental navigation system by the development and enhancement, which is called eLoran, and that consists of advancement of receiver and transmitter and of differential Loran in order to increase the accuracy of current Loran-C. A significant factor limiting the ranging accuracy of the eLoran signal is the ASF in the TOAs observed by the receiver. The ASF is mostly due to the fact that the ground-wave signal is likely to propagate over paths of varying conductivity and topography. This paper presents comparison results between the predicted ASF and the measured ASF in a southern east region of Korea. For predicting ASF, the Monteath model is used. Actual ASF is measured from the legacy Loran signal transmitted Pohang station in the GRI 9930 chain. The test results showed the repeatability of the measured ASF and the consistent characteristics between the predicted and the measured ASF values.

Wireless sensor networks have been researched to gather data about events on sensor fields from sources at sinks. Multipath routing is one of attractive approaches to reliably send data against the problem of frequent breakages on paths from sources to sinks due to node and link failures. As mobile events such as humans, animals, and vehicles are considered, sources may be continuously generated according to the movement of the mobile event. Thus, mobile events provide new challenging issue in multipath routing. However, the research on multipath routing mainly focus on both efficient multipath construction from sources to static sinks and fast multipath reconstruction against path breakages. Accordingly, the previous multipath routing protocols request each source continuously generated by a mobile event to construct individual multipath from the source to sinks. This induces the increase of multipath construction cost in the previous protocols in proportion to the number of source. Therefore, we propose efficient multipath routing protocol for supporting continuous sources generated by mobile events. In the proposed protocol, new source efficiently reconstructs its multipath by exploiting the existing multipath of previous sources. To do this, the proposed protocol selects one among three reconstruction methods: a local reconstruction, a global partial one, and a global full one. For a selection decision, we provide an analytical energy consumption cost model that calculates the summation of both the multipath reconstruction cost and the data forwarding cost. Simulation results show that the proposed protocol has better performance than the previous protocol to provide multipath routing for mobile events.
