The purpose of this study was to Investigate about current status of authentic science performance assessment in elementary schools. A total of 707 elementary teachers was involved and the data from questionnaire was gathered. The questionnaire was comprised two categories: items on the epistemological aspect & items on the actual condition. The major findings are as follows: 1. There are some elementary teachers who don't have a clear understanding on what authentic science performance assessment is even though most of teachers admit the importance of authentic performance assessment in their science teaching. 2. Malty teachers have chosen and have used experimental activities or performance tasks rather than they have developed tasks of their own. 3. Malty teachers have pointed out 'tile lack of time for performance assessment preparation' and 'the limitation of class time' as tile problems of working on science performance assessment in elementary schools.

Portfolio assessment provides many opportunities to foster children's creativity and to increase their responsibility for learning. few research study has been conducted in this area, and this assessment method has scarcely been administered in primary science class, Proper and effective use of portfolio assessment in our primary science class requires basic research on how to design and administer the method. Based on the earlier study on typical structures and components of portfolio assessment, the assessment instrument was developed on various primary science topics, The development team was consisted of one science education specialist and nine pre-service elementary school teachers. It takes ten months to develop instruments for 27 class hours. The development process was reciprocal in that development and revision cycle was repeated more than 7 times. The portfolio assessment instruments consist of instructional objectives, developers' evidence for the objectives, and assessment criteria. Adopting a new way of assessment into science class inevitably causes lots of confusions to teachers and children. The absence of basic research studies must be a critical barrier for successful administration of a new assessment method such as portfolio assessment. further research is required in the preparation and administration of portfolio assessment in our primary science classroom.

One major safety issue of surface operations is the occurrence of runway incursions. Runway incursions are the consequence of multiple operational and/or environmental factors. Human error is known to contribute to almost every runway incursion. One major contributing factor for runway incursion is crew's lack of situational awareness during airport surface operations, induced by weather considerations, by complex airport factors or by crew technique itself; it is also caused by ATC issues. Various airport factors may affect pilot situational awareness, distract the crew, or lead to crew confusion. The recommendations to avoid runway incursions are manifold; Proper Crew's CRM/TEM skills, adequate communication technique, proper knowledge of airport surface markings, lights and signs and preparation of preparation of expected taxi out/in routing. Also runway incursion risk assessment on specific airport before flight may lead to aware of risk level and contribute to prevent runway incursion.

In Korea, health-related items under current EIA (Environmental Impact Assessment) system can only be found in the categories of hygiene and public health. However, environment and public health are not adequately connected and also health is underestimated even though health is an important component of environmental assessments. As a result, health is not well integrated within criteria for investigating the impacts on environment. International trends in HIA (Health Impact Assessment) to strengthen the connection between environment and health were investigated in this research. Definitions, functions, circumstances, and merits of HIA in foreign countries were compared. By collecting and analyzing international organizations' and other countries' data related with HIA and EIA, preceding conditions and execution plans were suggested to link EIA and HIA from SEA (Strategic Environmental Assessment) aspects and to successfully accomplish EIA in Korea. According to this research, EHIA (Environmental Health Impact Assessment) can predict and manage the results of economical development only under the principles of inhabitants' participation, sustainability, and social justice. EHIA should be modified and improved towards increasing regional and national capabilities. For this, preparation of adequate procedure is required to connect EIA and HIA.

The statistics of monitoring on soil quality is a report statistics which is made on the basis of Article 15, Environment Strategy Basic Law and Article 5, Soil Environment Conservation Law. This study was conducted according to quality assessment of Korea National Statistical Office. The assessment of quality infrastructure advised that the authority bring up and increase completely responsible officer and secure the budget. The assessment of user satisfaction and reflection of request propose that the statistics is focused on soil background concentration, decrease soil sampling points and extend survey period. The assessment of error management system per processes of detailed preparation suggest change of the statistics objective, a reduction of sampling points and improvement of survey period and soil measurement properties. Accuracy assessment of data proposed cuts of sampling points, accessibility increment and build up of management system linking subordinates and Ministry of Environment. The substantiality assessment of data service demonstrated information environment improvement for users including reference expression and records of statistics table and figure contents.

Objectives: This study is designed to evaluate the influential factors of career decision-making self-efficacy and career identity by health science college students on their job preparation beaviors. Methods: The total 714 questionnaires were distributed to juniors and seniors of health science college, and the result was statistically analyzed through IBM SPSS statistics 20.0. Results: 1. There was no significant difference of job preparation behavior between male students and female students, and while seniors showed highly active job preparation behaviors, those who had high satisfaction level toward their major studies, high academic achievement, and outgoing personality had highly active job preparation behaviors. 2. Students with high satisfaction level toward their major studies, high academic achievement, outgoing personality, and high expected salaries showed high career decision-making self-efficacy level. 3. Students with high satisfaction level toward their major studies, high academic achievement and highly outgoing personality showed high level of career identity. 4. Subsidiary factors of career decision-making self-efficacy were collection of job information, goal setting, planning, and self-assessment, and all of them showed correlation with job preparation behaviors. 5. Among subsidiary factors of career decision-making self-efficacy, "self-understanding" and understanding of job information showed correlation with job preparation behaviors. Conclusion: For improvement on career decision-making self-efficacy and career identity of health science college students, individual support, psychological support, educational support and other supports regarding job employment to provide wide paths and methods for job preparation behaviors are essential, and through various job employment education program and graded counseling, job preparation behaviors shall be promoted as a great strategy.

This study is focused on a climate data integrity to improve water quality assessment due to the social development projects. The study is in an attempt to calculate both extreme ranges of weather data measurements and partly provide means to assess qualification of data which fall within the extremes at the 23 meteorological weather stations. Generally speaking, maximum temperature, minimum temperature, relative humidity, dew point temperature are in the range of reasonable accuracy. However, there found some outliers of the brightness sunshine hours in Cheonan station. Also some years in Gwangju, Seoul, Wonju, Busan, and Jeju never reach to their upper limit and perhaps the calibration of the equipment is doubtful. The users need to take cautions in using the brightness sunshine hour data in preparation of water resources planning and management by estimating evapotranspiration and river discharge, and/or growth rate of the algae (phytoplankton).

Railway risk is evaluated by a method of linking event trees and fault trees as the general PSA(Probabilistic Safety Assessment) model for the risk assessment of complex systems. Accident scenarios causing undesirable events are modeled by event trees comprised of several accident sequences. Each branch located in the accident progression of the event tree is modeled by an fault tree or can be represented by some value too simply. We usually evaluate the frequency of the whole sequence by adding them after calculating the frequency of each sequence at a time. However, since there are quite a number of event trees and fault trees in the railway risk assessment model, the number of sequence to evaluate increases and preparation for the risk assessment costs much time all the more. Also, it may induce errors when analysts perform the work of quantification. Therefore, the systematic maintenance and control of event trees and fault trees will be essential for the railway risk assessment. In this paper we introduce an integrated assessment method using one-top model and develop a risk assessment tool for the maintenance and control of the railway risk model.
