Recently, there has been a growing focus on the concerns pre-service teachers have as they move through different stages of their teacher preparation programs. Accordingly, the purpose of this study was to investigate pre-service secondary music teachers' concerns about music teaching and learning. The specific research questions were as follows: (a) What concerns are most common among participants? (b) What are differences in the concerns of pre-service secondary music teachers based on their stage of teacher preparation? (c) What are differences in the concerns of pre-service secondary music teachers based on their previous teaching experiences? A survey was distributed to pre-service secondary music teachers in a university in Seoul, and responses from a total of 93 participants were included in the final analysis. Data analysis indicated that pre-service music teachers experienced more concerns related to teaching tasks and student impact than themselves. Also, as participants progressed through their teacher preparation programs, self concerns decreased while task concerns and student impact concerns increased. Pre-service secondary music teachers who had previously taught in a school had fewer concerns than participants with no teaching experience. Suggestions for how teacher preparation programs can address the concerns of pre-service secondary music teachers are offered.

This study aims to examine the effect that the degree of knowledge about country-of-origin labeling on country-of-origin labeling work performance, which is a culinary staff task. This study is also intended to analyze differences in knowledge depending on hours of origin labeling education, and the moderating effect of education hours in the relationship between knowledge and performance. This study targeted culinary staff members working in ten five-star hotels in Seoul. A total of 205 self-administered questionnaires were distributed from November 14th to 27th, 2014, and 240 questionnaires(98.4%) were used for analysis after the exclusion of 4 with unreliable responses. Based on the data collected, frequency analysis, reliability test, exploratory factor analysis, simple regression analysis, t-test and moderating regression analysis were conducted using SPSS 18.0 program. The study findings are as follows. Culinary staff knowledge of origin labeling had a significantly positive effect on job performance and the degree of knowledge was higher in the group that attended one to two-hour periods of education. This suggests a differences in knowledge depending on the hours of education, which then had a moderating effect on the relationship between knowledge and performance. In conclusion, in order to improve knowledge of country-of-origin labeling and the level of performance, there is a need to increase education hours and enable culinary staff memebers to learn more knowledge and apply it to actual tasks. Based on these results, the limitation of the study and the direction of future research were also discussed.

Relational databases used by structuralizing data are the most widely used in data management at present. However, in relational databases, service becomes slower as the amount of data increases because of constraints in the reading and writing operations to save or query data. Furthermore, when a new task is added, the database grows and, consequently, requires additional infrastructure, such as parallel configuration of hardware, CPU, memory, and network, to support smooth operation. In this paper, in order to improve the web information services that are slowing down due to increase of data in the relational databases, we implemented a model to extract a large amount of data quickly and safely for users by processing Hadoop Distributed File System (HDFS) files after sending data to HDFSs and unifying and reconstructing the data. We implemented our model in a Web-based civil affairs system that stores image files, which is irregular data processing. Our proposed system's data processing was found to be 0.4 sec faster than that of a relational database system. Thus, we found that it is possible to support Web information services with a Hadoop-based big data processing technique in order to process a large amount of data, as in conventional relational databases. Furthermore, since Hadoop is open source, our model has the advantage of reducing software costs. The proposed system is expected to be used as a model for Web services that provide fast information processing for organizations that require efficient processing of big data because of the increase in the size of conventional relational databases.

In order to analyze the influence of career self-efficacy on risk taking level in university students, career self-efficacy which becomes the basis of active occupational exploration was classified into four items including self evaluation, goal setting, occupational information and problem solving. Risk taking level was divided into three items of occupational selection, monetary management and human relation. 450 surveys were distributed to four-year university students in Seoul, capital area and rural area for three weeks from November 26 until December 17, 2011, among which 402 surveys were accepted as effective study subjects. Among items of career self-efficacy, most significant influence on self evaluation was shown in group with high risk taking level in monetary management, and problem solving had most significant influence in groups with high risk taking level in occupational selection and human relation. As a result, occupational information was found to have negative (-) influence on all items of risk taking level, with increasing degree of influence on occupational information for subjects showing lower degree of risk taking level. This study provides detailed analysis on individual's work task called risk taking level based on different occupational types, offering new verification of career self-efficacy as the most fundamental element of occupational exploration to university students looking for employment.

Linking of the national R&D information between different ministries is a difficult task because they were all constructed independently. A standard infrastructure for the dissemination of such R&D information is required. This paper suggests a distributed integration method for the effective linking, gathering and integration of national R&D information. R&D management institutes designated by each ministry will gather and manage all the R&D information produced using the budget by the ministry and the information required for the integrated management of national R&D will be gathered from this information. Standardization of the R&D information, linking procedure and the construction method for the data linking software will be defined in this paper. The usage of R&D information will be processed more effectively to maximize the utiliation and productivity of national R&D activities.

Semantically-operated services, which is different from Web services or semantic Web services with semantic markup, can be defined as the services providing search function or reasoning function using ontologies. It performs a pre-defined task by exploiting URI, ontology classes, and ontology properties. This study introduces a method for pipelining semantically-operated services based on a semantic broker which refers to ontologies and service description stored in a service manager and invokes by user constraints. The constraints consist of input instances, an output class, a visualization type, service names, and properties. This method provides automatically-generated service pipelines including composit services and a simple workflow to the user. The pipelines provided by the semantic broker can be executed in a fully-automatic manner to find a set of meaningful semantic pipelines. After all, this study would epochally contribute to develop a portal service by ways of supporting human service planners who want to find specific composit services pipelined from distributed semantically-operated services.

Conventional exhibition management information systems recommend tourist attractions that are close to the place in which an exhibition is held. Some recommended attractions by the location-based recommendation could be meaningless when nothing is related to the exhibition's topic. Our goal is to recommend attractions that are related to the content presented in the exhibition, which can be coined as content-based recommendation. Even though human exhibition curators can do this, the quality is limited to their manual task and knowledge. We propose an automatic way of discovering attractions relevant to an exhibition of interests. Language resources are incorporated to discover attractions that are more meaningful. Because a typical single machine is unable to deal with such large-scale language resources efficiently, we implemented the algorithm on top of Apache Spark, which is a well-known distributed computing framework. As a user interface prototype, a web-based system is implemented that provides users with a list of relevant attractions when users are browsing exhibition information, available at http://bike.snu.ac.kr/WARP. We carried out a case study based on Korean Tourism Organization Linked Open Data with Korean Wikipedia as a language resource. Experimental results are demonstrated to show the efficiency and effectiveness of the proposed system. The effectiveness was evaluated against well-known exhibitions. It is expected that the proposed approach will contribute to the development of both exhibition and tourist industries by motivating exhibition visitors to become active tourists.

Since the September 11, 2001, transnational crimes and terrorism have increased, the importance of border security has been emphasized and integrated CIQ capability has been required. The U.S., Canada, and Australia are consolidating CIQ to strengthen border security, focusing on strengthening travelers and goods immigration control and airports, ports and land border security. In 2003, the U.S. established the Customs and Border Protection(CBP) under the Department of Homeland Security. Canada also established the Canada Border Services Agency(CBSA) under the Public Safety Canada in 2003. The Australian Customs and Border Protection Service was integrated with the Department of Immigration and Border Protection(DIBP) and the Australian Border Force was established in 2015. However, Korea operates a distributed border management system for each CIQ task which is unable to respond to complex border threats such as illegal immigration, entry of terrorists, smuggling of drugs, and gun trade in the airports, ports and land borders. In order to solve this problem, it is possible to consider integrating sequentially the customs and quarantine services which have high similarities, and to integrate the entire CIQ tasks with the Korea Customs Service delegated to the immigration control duties in the mid to long term. There is also a plan to benchmark the CIQ single accountability agencies in the U.S., Canada, and Australia in accordance with the Korean situation and to establish a new integrated border security organization.
