We discuss the paper by Cho, Shin, Lee, and Han on the "information-relate" undergraduate statistics major program from the following perspectives: Recently, Korean universities are under re-structuring turmoil. To effectively confront the situation, we need both the vision and the strategy for statistics and statistics departments. For undergraduate statistics major program, our visions are 1) it should not be preliminary education program targeted for the graduate degrees, 2) it should be responsive to future social demand, and 3) it should incorporate the progressive identity of statistics as information and data science. As strategies, we propose 1) the effective integration and due balance among data collection, management and analysis, 2) the harmony and role development of computers and mathematics as statistical tools, 3) the statistics education through task-oriented problem solving, and 4) the emphasis of team work and communication skills.on skills.

현재의 인터넷은 라우팅과 어드레싱에 대한 심각한 확장성 문제를 가지고 있다. 이러한 확장성의 가장 큰 원인은 멀티호밍, 트래픽 엔지니어링, 집적되지 못하는 주소 할당 등이며, 이로 인하여 백본 지역의 라우팅 테이블 크기가 기하급수적으로 증가하는 현상을 보이고 있다. 또한 현재의 IP 주소는 호스트의 식별자와 위치자의 의미를 함께 사용하기 때문에 호스트의 이동성 및 멀티호밍을 지원하는 데 한계점이 있다. 이러한 현재 인터넷의 문제점 해결 방안으로 식별자와 위치자 분리 구조가 연구되고 있다. 본고에서는 식별자와 위치자 분리 구조에서 필수적으로 요구되는 식별자와 위치자 간의 매핑 시스템에 관한 연구들을 소개하고 각각의 장단점을 분석한다. 본고에서는 현재 인터넷 기반의 대표적 식별자와 위치자 분리 구조 중 IETF(Internet Engineering Task Force)에서 잘 알려진 LISP(Locator Identifier Separation Protocol), HIP(Host Identity Protocol), ILNP(Identifier Locator Network Protocol)에서 제안하는 매핑 시스템들과 미래인터넷 기반의 대표적 식별자와 위치자 분리 구조 중 미국의 MobilityFirst와 한국의 MOFI(Mobile-Oriented Future Internet)에서 제안하는 매핑 시스템들을 중점적으로 소개한다.

Test situations are relatively specific and are experienced by everyone. The major purposes of this overview are to review the current concepts and theories of test anxiety and based on this review to suggest future directions in test anxiety theory and research. Test anxiety can be explained in terms of drive-oriented approach. trait-state anxiety theory, cognitive theory, cognitive and emotional approach, and psychodynamic theory. Usually, high test-anxious students keep the following characteristics : 1) The test situation is seen as difficult, challenging and threatening. 2) The individual sees himself as ineffective, and inadequate in handling the task at hand. 3) The individual focuses on undesirable consequences of personal inadequacy. 4) Self-deprecatory preoccupations are strong and interfere or compete with task-relevant cognitive activity. 5) The individual expects and anticipates failure and loss of regard by others. Future directions in test anxiety research should be focused to elucidate the nature and construct of test anxiety and the etiological factors of test anxiety by conducting research on the relationship between parental or social attitude and test anxiety. The effects of test anxiety on memory, attention, and cue utilization should be performed to elucidate the relationship between test anxiety and performance.

This study tends to apprehend how much public library contributes to a role of upbuilder of digital integrated local society through a survey. For this, I performed the survey on 935 organization of public library in the whole country registered in national library statistical system. As a result, firstly, it's apprehended that equipment infra, Internet infra, etc like computer, laptop, scanner, tablet PC, etc are in relatively high level. Secondly, service or resource like electronic book, digital and virtual reference service, library service mobile App, etc that users can use are in relatively high level but software supporting cooperation and group task, fusibility of participating space, etc are shown very low level. Thirdly, the rate of literacy training relating to technology were only 22.4%, education subject focused on resource searching subject and somewhat future-oriented technical education like directions of video conference technique, cloud computing application education, etc wasn't conducted. Finally, we should consider expansion of providing technology and equipment and provision of future-oriented service and education according to a flow of the time that needs to seek change in various roles of library as enjoying culture space or creative space.

Private security will be of great importance in the coming 21st century. In the future, most of the crimes will be violent and frequent. In order to prevent crimes private security must be dealt with in public service area and private area. For this reason, nowadays studies on private security is going on actively. But in reality, serious studies on theoretical backgrounds of private security has not been made yet. Currently, almost all of the theories propose various grounds, such as administrative, economic, and social grounds. And they are based on five backgrounds, that is, profit-oriented enterprise theory, economic reduction theory, vacuum theory, interest group theory, and private management theory. The article furnishes several grounds in addition to these. They are local self-government, management of local self-government, and task-force of guard enterprise. In this article, I am going to present some perspectives in classifying the theories. They are administrative, economic, and social perspective. They are shown as follows by figure. In conclusion, based on theoretical backgrounds mentioned above, private security will be advanced constantly in the future. But in carrying out studies on private security, approaching method of proposing the developmental model is more important than theoretical approaching method.

Purpose: Shared mobility services are the most notable in the shared economy; however, they have yet to be activated in Korea due to various regulations and conflicts amongst stakeholders. Nevertheless, shared mobility has become an irresistible trend of the times, as it can cause a great deal of economic and environmental benefits. In this vein, the purpose of this study is to contribute to the revitalization of shared mobility services in Korea and to provide service providers with implications for developing consumer-oriented marketing strategies. Research design, data and methodology: Based on the reasons that the users do not use shared mobility service, the factors influencing the behaviors of shared mobility users are structured and analyzed in a reliable, technical and procedural manner. To this end, the theory of reasoned action (TRA) of Ajzen and Fisbbein, the initial trust model (ITM), task technology fit (TTF) and switching cost (SC) are adopted. A total of 202 questionnaires were collected from the respondents who were aware of shared mobility. Then statistical processing of the collected data used SmartPLS(v.3.2.8), a PLS-SEM (Partial Least Squares Structural Equation Modeling) analysis program. The steps of the analysis are as follows. First, a PLS-Algorithm analysis was performed to evaluate the measurement model, and a Bootstraping and Blindfolding analysis was performed to evaluate the structural model and verify the hypotheses. Second, a multi-group analysis (PLS-MGA) was conducted to further analyze the differences depending on whether or not users experienced shared mobility service. Results: The results showed that initial trusts model (ITM) and task technology fit (TTF) have positive effects on users' behaviors through the mediation of the intention to use. As opposed to the assumption, switching costs did not have negative moderating effects in relation to the intention to use and users' behaviors. The influence of IT self-efficacy was significant, depending on the prior experience to use shared mobility services. Conclusions: This study will contribute to the revitalization of domestic shared mobility services and the formulation of service providers' marketing strategies. In future studies, there is a need to explore, reconstruct, and validate factors other than the impact factors of the shared mobility services used in this research model.

During last five years several workshops and seminars among social work educators, in and out country, has taken place. In those gatherings there has been, criticism on American model on which curriculum of social work in Korea has mainly based, and many proposals which most developing countries should consider and adopt for developing their own curriculums. The proposals could be summarized as follows; 1. Specification of developmental functions of social work should be made so that the curriculum could involve. It also must come from own societal needs and own national development task. 2. Social work should participate and make contribution to plan and solve the main social problems in own countries. 3. Clarification of educational objective in undergraduate level should be made and one of them must be related to the first professional degree. 4. There should be the courses which provide the content of macro level participation. How much of the proposals are reflected in the current curriculum of Korea? What are the problems Korean social work education has been faced in connection with reflecting the proposals? What kinds of task we should or could perform in order to adopt the proposals? These are the questions which deserved to be studied. The followings are the answers to the questions; 1. The new courses such as social welfare policy and planning, Social Development, Population Dynamics and Family Planning, Social problems, Special Issues in Social Welfare, etc, are placed in the curriculum. 2. Though the new courses are added the courses of case work, group work, and community organization are strongly remained it means that integrative method is not quite adopted and that conflicts are taking place between new and old fashion. 3. Fieldwork placement policy has been changes from concurrent to block and from social work method oriented to social problem oriented. 4. There are lack of integration among the all courses, of consistency between pre and post courses and connection among the related courses. 5. Establishment of image of social worker with B, A. degree should be urgently taken place. It can't be done by social work field alone but by cooperation with all the forces related to the social work practice. 6. B. A. graduate should have a common base of knowledge and competence. It could be come from the clear and specified objectives of undergraduate level education. And agreement among the member schools on the objectives can call on the fundamental similarities in each curriculums. Different programs from one school to another can be tolerated as long as there are fundamental similarities among the schools. Basic concepts and framework of social work should be kept clearly. It is a slow and long process to make social work recognized as a profession in the developing countries. Korea can't be and exception. Failure of having social work be indegenous can't be the reason to refuse an change the basic concepts of social work. One of he most important task which social work education in Korea must achieve in the near future is to establish the minimum requirement courses in the curriculum. Social work field, on the other hand, must find the positions for the social works in the various settings and institute. Clear role and image of social worker can be obtained by doing that.

Companies must capture value for sustainable growth. Capturing value is a critical task for companies, particularly when operating own businesses and organizations or starting new business. The business strategy of many companies focuses on capturing the maximum value from customers and other stakeholders. Even though a wide range of studies on value creation and appropriation has been conducted in the strategic management field, most of studies are still conceptual and theoretical. Thus more empirical studies are required to suggest future-oriented value strategy. This study reveals the value creation and appropriation elements in the aviation industry of Korea. The purpose of this study is to understand the trend of value creation and appropriation in the industry. In addition, the relationship between the elements and firm's performance are tested. The firm's performance is defined by that past and future point of views. The sample were collected from Korean Air and Asiana Air. The empirical test shows that the elements of value creation-appropriation have significant impact on firm's performance. Further, the element of value appropriation to customer has a positive impact both on firm's past and future performance. Our results show that investors acknowledge a value-based strategy as a sign of stock valuation. The results of this test correspond with the earlier one, showing that maximizing customers value rather than shareholder value does deliver impressive returns. The finding suggest that companies need to change their strategy to efficiently manage performance. With the test results, we propose a value-based strategy to maximize firm's future financial and stock performance.

The progress of environmental science and technology in the developed countries has been rapid in recent years. Particularly remarkable has been the advancement of various pollutant control measures, which have brought the pollution of inorganic factors such as air and water under control. In contrast, diversity of the ecosphere, of which man is a part, is being steadily impoverished and the biological community is getting unvaryingly uniform. These phenomena were brought about by the expansion of artificial environment such as new industrial complexes, transportation facilities and urban development. Man has constructed uniform and artificial environment, believing in the premise of confrontation with nature, to such a scale that the natural environment and biological community have lost their balance. This will increasingly endanger the soundness of the biotic environment of nature, which constitutes the potential foundation both for the survival environment of man as biological entity and for the development of human civilization. In order to guarantee the soundness of man's body, intelligence and sensitivity as wholesome gene pool on the earth and for the future of man, primarily important environmental education is the understanding of how man can everlasting exist in and with the survival environment. In view of this reality, it is vitally important to create ecologically diverse and well-balanced environment with living materials, i.e., vegetation in order to secure lasting survival environment for man. This task is urgently required in highly artificial environment where non-biological materials have forced the impoverishment of the biological community. Therefore, environmental education for the future should not be totally oriented to technology as that in the past nor it is limited to the medical aspect where well-being of human is the sole object of concern. That is to say, environmental education for the future should be one that provides knowledge that human can understand his place based on the ecological concept and thereby make him to have ethical consciousness that he can control his behavior within the reasonable level for ecological niche who he is located.
