  • Although the demand for the use of public data increases in accordance with the expansion of Government 3.0, the poor level of data quality and its management currently implemented is becoming obstacles to opening data to the public. To improve the efficiency of management, linkage and usage for data, standardized processes for data quality management have to be prepared and appropriate data quality assessment criteria should be established. In this paper, we propose the organizational maturity model that can assess the public data quality management level. This model consists of the process reference model and the measurement framework. Fifteen processes grouped by the PDCA cycle are defined in the process reference model. The measurement framework measures the organizational maturity level based on process capability levels. The organizational maturity model can be used to establish objectives and directions for public data quality improvement by diagnosis of current level of public data quality management and problem solving. This model can also facilitate open to the private sector and activate usage of stable public data through reliability enhancement.

  • Incident detection rate and false alarm rate are the key measures tot estimating the performance of automatic incident detection algorithms. It is, however inherently very difficult to improve the two measures simultaneously. The main purpose of this study is to present some methods for solving the problem. For this, an incident detection algorithm has been designed in this study. The algorithm is consisted of two functions, one for detecting incident and another for detecting congestion. A logic for distinguishing non-recurrent congestion from recurrent congestion was employed in the algorithm. The new algorithm basically requires speed, flow, and occupancy data for defining incident situation, but the algorithm is able to perform this task without one of the three parameters. The performance of the algorithm has been evaluated by using the field data collected from Interstate Highway 880 in Bay Area, California. The empirical analysis results are very promising and thus, the algorithm proposed may be very useful for the analysts. This paper presents some empirical test results for the performance of California incident detection algorithm, only for the reference purpose.

  • In the several decades, various storage facilities have been developed and operated to supply water resource, flood control or environmental preservation etc. Then, how those man-maid storage facilities affect on the downstream water and environment and how the hydrologists can evaluate those features for water resources problem-solving are high-concentrated problems in this field. Most large watersheds in Korea contain various types of artificial facilities such dams, reservoirs, in-land ponds, wetlands etc. But the study to develop the technology for achieving the effect of the variances and properties of the long term streamflow caused by the artificial storage facilities have been on the simple watershed models and experimental modeling in the real fields. In this paper, we introduce the procedure and methods to consider the above problems based on continuous and semi-distributed featured SWAT model. At the first, we describe the elements and mechanisms of storage facilities in SWAT model to see how we can apply that in proper and appropriate manner for real field problems. Then, we applied the process to a sample watershed, Taewha River basin which covers the most of Ulsan region. Specially, we concentrate on our effort to the effect of upper reservoirs on down stream long term flows based on various scenario basis. The result was described and analysed in spacial and temporal variations on that basin using the precise manner.

  • Many countries, including Canada, operate a sonographer license system separately from a radiological technologist license. However, in Korea, radiological technologists perform ultrasound imaging under the guidance of doctors. Therefore, in order to have the opportunity to provide a systematic education by analyzing the job competency of the radiological technologist's ultrasound imaging, based on the Canadian National Competency Profile (NCP) lists, this study measured the job content validity of the job competences and detailed competencies required for performing ultrasonography in Korea. From the results of comparing and analyzing the importance of the core competencies included in the Korean radiological technologist's job competencies and the degree of job performance, the average overall importance was 4.087, the average of overall performance was 3.640, showing that the importance was higher than the performance and that there was a statistically significant difference. In conclusion, 'A Communication', 'B Professional responsibilities', 'D Operation of equipment' and 'G Workplace health and safety' showed high job content validity. However, it is said that as 'C Patient assessment and care', 'E Critical thinking and problem solving', and 'H Image' showed low job content validity, it is necessary to seek ways to strengthen and complement these competencies.

  • Providing gifted education should be based on the principle of differentiation, that is, paying close attention to the individual characteristics of the gifted. The gifted are known to be the fast learners with autonomous studying ability and high levels of thinking and creativity, which certainly differentiate them from the ordinary others. Thus, the program for the gifted should fundamentally differ from other general programs. The need for gifted education is growing as our society has turned into the knowledge-based society. Fortunately, on December 28th, 1999, a law in favor of gifted education was passed. According to the law, gifted education will be actively provided under the government's support from the year 2002. In this context, this study is intended to search for the model of developing instructional materials for the gifted. The output materials of this study are to be used in gifted schools which will be built in the near future. The curriculum for the gifted consists of three parts: basic curriculum, in-depth curriculum, and optional curriculum. The learning and instructional materials developed in this study are to be used for the in-depth curriculum. In order to develop the materials, various theoretical models related to gifted education were reviewed. Finally, a theoretical model was developed. On the basis of the model, several instructional materials are developed and the possibility of application are considered.

  • The purpose of this study is to analyze the status and gifted students' perception on curriculum implementation for gifted education at Busan Science Academy. For the purpose, we investigated the curriculum documents, the process of implementing curriculum and the result of the questionnaire. The questionnaire about the curriculum courses, teaching strategies and evaluation method was answered by 143 students at Busan Science Academy. The curriculum courses are composed of general courses and specialized courses: general courses comprise of Korean language, social studies, foreign languages, arts, and physical education. Specialized courses consist of mathematics, physics, chemistry, biology, earth science, information science. Elective courses are divided into basic elective courses and in-depth courses. Each in-depth course deals with more specialized content. The significant results of the questionnaire are as follows: First, according to gifted students' perception, the credits of specialized courses and in-depth elective courses need to be increased and the credits of general courses need to be reduced. Second, teachers at this school mainly use teaching strategies such as lecture, group activities and discussion, but the students prefer diverse teaching strategies such as lecture, discussion, experiment, individual research, problem solving and field studies. Third, students prefer a paper-and-pencil testing assesment rather than a written report assesment and lab experiment assesment. According to this study, the characteristics of the acceleration curriculum at Busan Science Academy were too intensive. Thus it is difficult to implement the enrichment education according to the demand of gifted students in this school. Therefore, this study suggests that we need to revise the curriculum courses of Busan Science Academy and develop contents and strategies for gifted education in science and mathematics.

  • Beginning with retirement in 2010 of the leading group of baby boomer generation born in 1955, baby boomers are starting to retire from work in full-scale. Since retirement of baby boomers refers to increase in the senior class with longer life expectancies caused by development of medical technologies, enhancement of living standards, and improvement of surrounding environments, annually decreasing birthrate is further accelerating entry of our society into an aged society. Accordingly to examine baby boomer generation's preparation for retirement in relation to career self-efficacy, first, difference in retirement preparation according to mean monthly income and current occupation was analyzed. Second, the effect of career self-efficacy on retirement preparation was studied. The survey for this study was conducted for one month between January 17 and February 16, 2012 in Seoul, Gyeonggi, Gangwon, Chungnam, Gyeongnam, Jeonnam, and Jeju. 500 surveys were distributed to baby boomer generations through direct visit and mail, among which 443 responses were returned. 400 effective responses were selected as subjects of the study. As a result, preparation for retirement according to mean monthly income was verified to be significant in terms of economic and physical factors. Significant results were shown in all factors including economic, physical and social factors for retirement preparation according to current occupation. Career self-efficacy had greatest influence of 58% on retirement preparation with economic factors. It also influenced all factors including self assessment, objective setting, occupational information, and problem solving.

  • The purpose of this study was to investigate the effect of the outplacement service on the career decision-making self-efficacy of discharged soldiers after mid- to long-term service. The survey carried out for this research was on 557 male discharged solders living in the Seoul, Incheon, and Gyeonggi areas. The information was processed using frequency analysis, factor analysis, reliability measurement, independent sample t-test, one-way ANOVA analysis, correlation analysis, and multiple regression analysis by means of the SPSSWIN 22.0 program. The results of this study suggest that counseling, education and training affect only some sub-factors of the career decision self-efficacy. Administrative support positively affects the job information collection skill, goal setting skill, planning skill, and problem solving skill among the sub-factors of the career decision self-efficacy. Job activities support had no effect on the career decision self-efficacy.
