The purpose of this analysis is to clarify the direction and nature of the future leading industries in Korea. Existing studies were analyzed in depth and their implications are as follows. Existing studies have not given a careful consideration for the structural adjustment of Korean economy and the atmosphere for the growth of prospective leading industries. In relation to the structural adjustment, the accomplishment of high value-added in existing industries and the promotion for high-tech industries as well as service industries should be the future direction of the future leading industries. In order to create atmosphere for the growth, it is crucial to achieve a social consensus about the nature of the prospective leading industries and is necessary to continue a concrete research on the related industries.

Effective traffic matrix estimation is the basis of efficient traffic engineering, and therefore, quality of service provision support in IP networks. In this study, traffic matrix estimation is investigated in IP networks and an Elman neural network-based traffic matrix inference (ENNTMI) method is proposed. In ENNTMI, the conventional Elman neural network is modified to capture the spatio-temporal correlations and the time-varying property, and certain side information is introduced to help estimate traffic matrix in a network accurately. The regular parameter is further introduced into the optimal equation. Thus, the highly ill-posed nature of traffic matrix estimation is overcome effectively and efficiently.

Recently, reinforced concrete structures exposed to severe enviroment are increased in metropolitan area. The acid rain and CO2 penetrated towad rebar, thus rebar corrosion occurred. The corrosion of rebar in concrete is, as in most corrosion processes, an electrochemical nature. The corrosion may severely affect on durability and service life of such a concrete structures. This study was performed for the purpose of acquiring data about corrosion condition and considering a countermeasure to prevent rebar from corroding due to carbonation of concrete. An accelerated car bonation testing procedure was applied to measure the evolution of carbonation and rebar corrosion with time for various water-binder ratios and cement types.

Initial science teacher education in Hong Kong is provided by the Post-graduate Diploma in Education Programme (PGDE) for both pre-service and in-service secondary school teachers. This programme includes a balanced treatment of subject curriculum and teaching in science, general pedagogical knowledge and skills, educational psychology and school administration. The science courses in this programme also have some units that equip science teachers with the knowledge and skills that are essential for teaching a science curriculum that emphasises conceptual change and understanding of the nature and methods of science. This emphasis is illustrated by two studies: (1) Developing a conceptual change model of instruction in Biology teachers, and (2) Constructing understanding of the nature and methods of science.

Confronting with series of environmental problems. caused by urbanization and the constantly improving consciousness of the entire society towards environmental protection, it has become an inevitable trend to develop parks and green space planning that guided by the principle of 'respecting nature, preferring ecology' and integrate function, arts and culture of landscape design. Aiming at specific project, humanized design should be laid stress on. With fundamental functional construction serving as the base, the reflection of cultural content and regional landscape as the characters, using various landscape gardening elements reasonably to enrich space design as well as highlighting leisure and sport function and following the concept 'human-centered', parks and green space filled with natural vitality and cultural spirit can be constructed, people, city and the nature could develop together in harmony.

This paper is to identify and assess vulnerabilities of services considering the nature of service layers for analyzing vulnerability of SOA security. It is a model driven approach which provides the way to present security requirements of the business model and identify the vulnerabilities of the services to extract the secure service model. We validate the proposed method with the analytic evaluation because the predictive nature of our methodology poses some specific challenges for its validation.

The objective of this study is to lead balanced development of tourism industry by proving the nature of customer service which is one of the service characters as well as ultimate goal of tourism industry. This paper contains a few case studies of service industry customer service and proposed desirable development plan. This study tried differentiate customer service from management side in its role. Meanwhile, management and tourism industry integration, partly in the service channel, is a task to be studied continuously in terms of customer satisfaction. Customer service should utilize for social welfare and improving the firm's competitiveness in the tourism industry

This paper originates from the questions concerning why Korea has had difficulties in boosting R&D service industries regardless of government efforts over a decade. We first review the intrinsic nature of the R&D services and set up four criteria such as establishment type, diversification of business models, coverage of client firms, and role of R&D service firms as innovation drivers and IP strategies, that will be used in interviewing and analyzing R&D service firms. Second, we carry out in-depth interviews of eighteen R&D service firms to understand business behaviors and relevant characteristics. Finally, we identify five groups of R&D service firms and conclude that differentiated polices have to be implemented according to the groups for promoting the industry effectively.

The purpose of this study is to examine Korean journals related to science education in order to analyze research trends into Nature of science in Korea. The subject of the study is the level of Korean Citation Index (KCI-listed, KCI listing candidates), that can be searched by the key phrase, "Nature of science" in Korean language through the RISS service. In this study, the Descriptive Statistical Analysis Method is utilized to discover the number of research articles, classifying them by year and by journal. Also, the Sementic Network Analysis was conducted to Word Cloud Analysis the frequency of key words, Centrality Analysis, co-occurrence and Cluster Dendrogram Analysis throughout a variety of research articles. The results show that 91 research papers were published in 25 journals from 1991 to 2015. Specifically, the 2 major journals published more than 50% of the total papers. In relation to research fields., In addition, key phrases, such as 'Analysis', 'recognition', 'lessons', 'science textbook', 'History of Science' and 'influence' are the most frequently used among the research studies. Finally, there are small language networks that appear concurrently as below: [Nature of science - high school student - recognize], [Explicit - lesson - effect], [elementary school - science textbook - analysis]. Research topic have been gradually diversified. However, many studies still put their focus on analysis and research aspects, and there have been little research on the Teaching and learning methods.
