The NSDI concept has changed with the development of the NSDI. While the NSDI was initially established as a separate entity, recently more attention has been given to the SDI hierarchy, from a local level to a global level. As an advanced NSDI, the USA, the UK and Canada emphasize more on better citizen services through an e-Government GIS portal such as the USA's Geospatial One-Stop. This study hypothesizes that the characteristics of NSDIs can be different from each nation in terms of vision, structure, evolution stages and a degree of integration with the e-Government. Rather than to describe differences just fur comparison, more characteristics of NSDIs are identified and the comparisons are developed as recommendations for the future NGIS(National Geographic Information System) in Korea.

In this study, the multiplicity of synchronous online class discussion activity is explored at conceptual level. From the cultural-historical activity theory (CHAT), each utterance may be considered as a product of the activity system. Alderfer's ERG theory is employed as another theoretical framework for the study. Based on the subject's existence, relationship, growth needs, their class discussion activities constitute four different dimensions: physical/biological, cultural/institutional, social/relational, and cooperative knowledge construction. It is inherent in individual activities and has a different arrangement according to their interests and situations, and at the same time acts as a factor of cooperation and competition among the participants. Through this, collective discussion activities represent complex and dynamic development patterns.

This study was to identify the concept of oppression in nursing organization thereby providing basic data on nursing education to improve oppression in nursing organization. Using Walker and Avant's criteria to identify attributes, antecedents, and consequences of oppression in nursing organization, 17 research articles published from 2006 to 2020 were reviewed. The defining attributes of oppression in nursing identified in this study were low self-esteem, lack of authority, and horizontal violence. The antecedents to oppression in nursing organization were oppressors, hierarchical organizational structure, and marginalization. The consequences of oppression in nursing organization included job satisfaction, organizational silence, patient safety and quality of nursing. Considering the findings, improvement of the hierarchical working environment in hospitals and self-awareness as professional nurses are important for nurses to overcome oppression in nursing organization. Therefore, effective educational programs should be developed to ameliorate working environment and self-awareness of nurses.

본 연구에서는 중사전 규모의 현대국어사전에서 약 5,000 개의 표제항목의 뜻풀이 8,000여 항에 사용된 어휘를 분석한 결과를 제시하였다. 분석 결과 명사류의 의미구조에서 최상위계층에 속하는 것들이 사전의 뜻풀이에 자주 사용됨을 확인할 수 있었고, 아울러 뜻풀이에 사용되는 단어들이 어느 정도 통제된 상태임을 알 수 있었다. 그러나 표제항목과 뜻풀이에 사용된 단어들 사이의 관계만을 바탕으로 해서는 의미망을 구축하기 어려웠는데, 그것은 국어사전에서의 뜻풀이가 지니고 있는 구조적 문제에서 기인하는 것이다. 즉 일부 한자어의 경우에는 명사로 정의되지 않으며, 그 결과 표제명사와 뜻풀이에 사용된 명사 사이의 관계를 바탕으로 한 의미망의 구축에 포함되지 않는 것이다. 또한 순환적 뜻풀이의 경우 역시 의미망 구축에 장애요소로 작용함을 밝혔다.

This study proposes a theory of consumer experiences based on a cognitive science framework that serves as an alternative to the mainstream marketing paradigm of information processing and choice. The theory consists of three key theoretical constructs: experiential modules, primary vs. secondary experiences, and the hierarchy of experiential modules. Based on this theory, this study investigates the effect of experiential attributes and functional attributes on consumer's product evaluations, and the moderating role of consumer's knowledge. The main research findings are (1) the subjects react faster to sensory and affective stimuli(ex: experiential attributes) than they do to intellectual stimuli (ex: functional attributes), (2) the interaction modularity of attributes(functional vs. experiential) $\times$ tempo(normal vs. fast) $\times$ product knowledge(novice vs. expert) appear significantly with product evaluation as the dependent measure.

Economic factors are important in improving life satisfaction of disabled people. In addition, the impact of job satisfaction on life satisfaction has been verified. However, according to Herzberg's motivation-hygiene theory, hygiene factors such as wages only lowers dissatisfaction and does not directly affect job satisfaction. This study raises questions about Herzberg's theory and seeks to confirm through empirical analysis. Based on data from the 2017 Employment Panel Survey for the Disabled, this study seeks to answer analyzes whether hygiene factors proposed by Herzberg affect the job satisfaction of disabled people or not. Furthermore, this study proposes what regional policies are needed to enhance job satisfaction for the disabled. An analysis of structural equation model showed that hygiene factors such as working environment, interpersonal relationship and personal life directly affect the disabled worker's job satisfaction. In addition, through hierarchical linear model analysis, it was confirmed that local governments ought to provide education supports to the disabled workers in order to improve their job satisfactions.

North Korea has been striving to promote a national informatization strategy after getting through the period of 'Arduous March'in the 1990s. First of all, North Korea has made organizations required for implementing the national informatization strategy. They reorganized and created the Science & Education Ministry, the Machine & Industry Ministry, and the 21 bureau under the Workers' Party of Korea while making special units in the Royal Mail, Royal electron & industry, National Academy of Sciences under cabinet. Then they completed all the essential organizational system for informatization including newly built specialized agencies: 'Korea Computer Center; KCC' & 'Pyongyang Informatics Center: PIC'. But North Korea's informatization system has a rigid hierarchy. All the organizations in the hierarchical system are controlled by the Workers' Party of Korea. It means that North Korea consider IT as a tool for the centralized control of the Party and the government. So, these characteristics of North Korea's informatization system clearly give us a picture that tells us what they want from the national informatization and where they're going.

For the empirical analysis in this study, 335 cabin crews from large airline companies and budget airlines were interviewed using self-reporting questionnaires. The data was analyzed using the SPSS 23.0 and AMOS 23.0. First, of the organizational culture types, the relationship-oriented culture, hierarchy-oriented culture, and task-oriented culture were found to have negative impacts on job stress. Second, the innovation-oriented organizational culture, relationship-oriented culture, and hierarchy-oriented culture were found to have positive impacts on empowerment. Third, empowerment was found to have a negative impact on job stress. Fourth, as for the mediating effect of empowerment, the innovation-oriented culture, relationship-oriented culture, hierarchy-oriented culture, and task-oriented culture were verified to be all significantly mediated by empowerment in their relationship with job stress. As a result, it was shown that cabin crews of airline companies found their work more fun, interesting, and valuable in an organizational structure that was more oriented toward flexibility, rather than the hierarchical, task-oriented cultures that are more focused on control and order. It was also found that empowerment was a mediating factor in the relationship between organizational culture and job stress.

This study analyzed the efficiency of a trunk with branches and a trunk with feeders route system comparing the user cost and operator cost of those route systems. Basically, a trunk with branches is more efficient than a trunk with feeders in the passengers' perspective if the transit system of a trunk and feeders are the same. In the case that the trunk system is hierarchically higher than the feeder system, a trunk with feeders has the competitive edge over a trunk with branches if the saving of travel cost induced by using the trunk line is larger than the increasing waiting and transfer cost. This result is consistent with the previous research by Park et al.(2007c), which analyzed the efficiency of hierarchical structure in a grid transit network. If the travel demand of each origins and destinations is low, increasing headway according to the travel demand can increase passenger load or operating efficiency in a trunk with feeders route system. In this case, a trunk with feeders route system is more prevalent as the operating cost, route length, and number of destinations increases, while it is less prevalent as the transfer cost and passengers' time value of the waiting time increases. In cases that central business district, which is located in the middle of a trunk line, generates travel demand, a trunk with feeders is more efficient than a trunk with branches with the increasing travel demand from and to the CBD. Therefore it can be concluded that to have a dual operating system between CBD and suburban is more efficient than one type transit system. The efficiency of that system can be increased through an efficient transfer system that can reduce the transfer cost.
