  • Abstract [] The prediction of changes in the tidal regime due to the sea dike closure in the Saemankum area was performed using the nonlinear finite element model, TIDE. Based upon an overall comparison of calibrated model results with available field data, the TIDE model behaves well and is good representation of the hydrodynamic of the Saemankum tidal project area. It is shown that the TIDE model does an excellent job of computing the changes of tidal characteristics resulting in sea dike closure in an estuary area.

  • For many years concrete has been the major building material for most construction. It is of primary importance that fire fighters or fire investigators have a full understanding of the properties of concrete so that better control of the fire scene is achieved. This, in turn, not only help to ensure a safer fire-fighting job but also a more successful fire investigation. So far as the fire scene investigation in concerned, knowledge about the thermal behaviour of concrete can help the investigators to determine the highest temperature that a particular spot of a fire scene has ever reached thereby providing data which may be of value in reconstructing the course of the fire.

  • Subcontracting business than the contracting business in shipbuilding industry is a lot of hazardous job and highly accident because of highly work intensity. In order to prevent the accidents, there is a need to analyze characteristic. of shipbuilding, to apply measures of risk assessment. In this paper, I suggested an improvement of the risk assessment through the actual condition research in shipbuilding industry. In the research method, I analysed accidents occurred until 2011-2013. Carried out the actual site survey while two weeks in May 2014. As a result, 1) The main pattern were caught-in or between, fall on the high level according to analyzed accidents. 2) To apply the weight show clear of magnitude for risk assessment. 3) Risk estimation of risk assessment is desirable to be quantization by accidents analysis, and to be greater than or equal to 4 steps.

  • In this study, we perform 3-D reconstruction of human proximal femur from DICOM files by using voxel mesh algorithm. After 3-D reconstruction, the model converted to Finite Element model which developed for automatically making not only 3-D geometrical model but also FE model from medical image dataset. During this job, trabecular pattern, one of characteristic of human bone can be added to the model by means of giving it's own elastic property calculated from intensity in CT scanned image to the each voxel. And then another model is made from same image dataset which have two material properties - one corresponds to cortical bone, another to trabecular bone. Finally, validity of voxel mesh technique is verified through comparing results of FE analysis, free vibration and stress analysis.

  • Possible directions of chemical engineering education have been proposed in many studies. However, new curriculum is demanded to accommodate the special needs of our students' level and community industrial characteristics. We can think of two reasons. One is that various kinds of chemical engineering industry are found in every community. The other is that students' educational standards are different in every university. We have surveyed and analyzed jobs of our university graduates who are working in chemical company of our community Pusan and Kyoung-Nam. This study aims to develop the new curriculum with an emphasis on practical education and to propose the new direction for our major characteristic based on the survey.

  • The purpose of the study is to review research in concept, measurement, effect, and influence factor of teacher efficacy. Through the review of previous research, the study shows that the concept of teacher efficacy is likely to be situation-specific rather than teacher characteristic. And the study represents that the measurement of teacher efficacy is related to the development of measurement instrument and the extraction of construct. The effect of teacher efficacy concerns the relationship between teacher efficacy and the student's academic achievement and affective traits such as motivation, interests, and attitude, and the relationship between teacher efficacy and teacher. And the influence factor of teacher efficacy concerns the influence of job environment related to teacher. The four things mentioned above are discussed in detail based on the previous research.

  • The program of practical training of architectural interior will be change for improvement of not only to complete design on the table but to be in employee market flexibly also. It's necessary to take the educational efficiency for the practical training in the course of intoner architecture. The characteristic of interior space in the model for useful practice is residential space. the interior construction to be controled generally on the central axis of interior architecture, although there were several items of construction which divided architectural structure, electrical power, air control est. the process of practical training is to be established not only with object of training, grade of skill, materials and equipments and tools of it's prepare and working, but safety on the job training.

  • This paper presents the safety performance of domestic small-sized construction companies including the characteristic and current status of safety management actions of the firms. Safety performance both at the head office and job sites of each construction companies, which are divided two groups by construction capacity ranking, are investigated. The investigation results on the small-sized construction companies in this study was compared with those of on the large and medium-sized construction companies studied in existing papers. General recognition that there is a wide difference of safety performance among domestic construction companies by construction capacity ranking was companies by this study. Especially, Data analysis shows that the safety performance of the small-sized companies has the larger difference than large and midium-sized companies.

  • Purpose: The aim of this systematic literature review was to synthesize and investigate the effects of shift workers' sleep in Korea. Methods: A search was conducted through three electronic databases using keywords such as "shift work" or "rotation work" and "sleep", with sleep as the independent variable, and 17 papers were reviewed. Results: The design of those 17 studies was analyzed in a cross-sectional analysis. The most commonly measured characteristic was quality of sleep, whereas the others were sleep disturbance, sleep efficiency, and sleepiness. The study outcome variables were job-related factors, mental health, wellness, stress, fatigue, and metabolic syndrome. Conclusion: The results inform sleep and health-promoting behaviors and improvement in shift workers' working condition.
