  • A methodology using neural networks has been proposed for rapid prediction of inelastic bending moments in reinforced concrete continuous beams subjected to service load. The closed form expressions obtained from the trained neural networks take into account cracking in concrete at in-span and at near the internal supports and tension stiffening effect. The expressions predict the inelastic moments (considering the concrete cracking) from the elastic moments (neglecting the concrete cracking) at supports. Three separate neural networks are trained since these have been postulated to represent all the beams having any number of spans. The training, validating, and testing data sets for the neural networks are generated using an analytical-numerical procedure of analysis. The proposed expressions are verified for example beams of different number of spans and cross-section properties and the errors are found to be small. The proposed expressions, at minimal input data and computation effort, yield results that are close to FEM results. The expressions can be used in preliminary every day design as they enable a rapid prediction of inelastic moments and require a computational effort that is a fraction of that required for the available methods in literature.

  • There can be a significant amount of moment redistribution in composite frames consisting of steel columns and composite beams, due to cracking, creep and shrinkage of concrete. Considerable amount of computational effort is required for taking into account these effects for large composite frames. A methodology has been presented in this paper for taking into account these effects. In the methodology that has been demonstrated for moderately high frames, neural network models are developed for rapid prediction of the inelastic moments (typically for 20 years, considering instantaneous cracking, and time effects, i.e., creep and shrinkage, in concrete) at a joint in a frame from the elastic moments (neglecting instantaneous cracking and time effects). The proposed models predict the inelastic moment ratios (ratio of elastic moment to inelastic moment) using eleven input parameters for interior joints and seven input parameters for exterior joints. The training and testing data sets are generated using a hybrid procedure developed by the authors. The neural network models have been validated for frames of different number of spans and storeys. The models drastically reduce the computational effort and predict the inelastic moments, with reasonable accuracy for practical purposes, from the elastic moments, that can be obtained from any of the readily available software.

  • In contemporary society, many fishery industries face a serious problem of having an insufficient number of junior ship officers and engineers. Even though many fishery high schools in Korea made significant effort to produce many talented junior officers and engineers, but after graduation, the students are reluctant to get a job on the fishing vessels. Furthermore, Korean government also invested a large amount of money to train students for ocean-going and costal & near-ocean fishing vessels. However, despite the government's great effort on the training program and education, only a few students wish to work on the fishing vessels. In this article, the author tried to find answers for various questions such as what are the factors that the student prefer, where the student to want to get a job in fishery industries, and how student feel about working at fishing vessels. Furthermore, the author also analyzed the differences between high school student group and Korea Institute of Maritime and Fisheries Technology(KIMFT) student group about occupational orientation by utilizing SPSS statistical program. Additionally, the author surveyed the current onboard status of job position of the high school and KIMFT alumni. This study's results and data will be used for aiding further stimulation and advertisement of job position in fishing vessels and continued daily lives on board.

In a circumstance that needed higher level of education, this study is aimed on realizing an importance of clinical training through the various materials that previously carried out and offering basic knowledge to take better clinical training for the students. Study results below 1. This Investigation conducted on 123 of sophomores(70.3%) and 52 of juniors(29.7%) who have been taken clinical training, and men's proportion(51.45%)is a bit higher than girls(48.6%). The 64% of respondents taken largest proportion were 20 to 24 years old. As 67.9% of respondents attended daytime school and 30.3% of them attended nighttime one, their school time shows a little difference. In a question about relation ship, one answered "Harmonious" took largest proportion by 72.6% during training, and about the degree of satisfaction of campus life who answered "normal" were the most with 59.4%. 2. About the reason choosing dental technology as a major, 41.1% taken the most answered "due to the specialized job", "Getting job easily" was second with 26.9%, and third was "recommended from around" with 18.3%. 50.3% of the respondents answered "normal" about the Satisfaction of their major, student marked in grade "B" most with 51.4% 3. In a investigation result about clinical training statues and preference, most(72.6%) choose place less than 10 for clinical training, and 60.6% of them resided own home. About their commuting time from home to training place, 44% was under 30min, 40% took time 30-60min. It shows students prefer shotter distance in terms of choosing training place. 4. Each part manager took large proportion as a clinical trainer with 33.7%, Training curriculum reform and developing method were most answer as a improvement measure after completing training with 30%. 5. The average of total score about clinical training was 3.15 of 5. In the detailed question, 'satisfaction of clinical training' got 3.38 as a highest score, the lowest score was 2.86 that is about satisfaction of clinical training period. The average score about efficiency of study was 2.86 and in detailed question, 'a Role model' got 3.26 as a highest score and participation of student got 3.05 as a lowest score. 6. The result of T-test to see the difference of the satisfaction according to the general character and clinic training condition between teaching efficiency is that the degree of satisfaction of clinical training showed statistical significance only in the degree of satisfaction of campus life(p<0.05), and teaching efficiency has a statistical significance with their age, grade, and satisfaction of campus life (p<0.05). 7. The relation between of teaching efficiency of clinical training and satisfaction of clinical training of dental technologic student has a statistical meaning in significance leveler 0.01. Now, therefore we suggest following based on these result. 1. To elevate satisfaction of clinical training, it agentry needs development of consistent clinical training curriculum. 2. To grasp the satisfaction and requirement, in needs to measure anxiousness and satisfactory degree after completing training 3. To train efficiently and evaluate efficiency over the teaching activities, it needs to develop measuring tools for teaching efficiency in terms of teacher's important rules in a clinical training. 4. Strengthen the relations with the study developing and managing curriculum gathering theoretical knowledge and practice. And make an effort to apply to their students. 5.

  • Construction industry has a relatively higher accident rate compared to other industries, especially the serious accident rate including death. Ministry of Employment and Labor has not only implemented safety consciousness but also initiated the basic occupational safety and health training for the construction industry. Despite the effort, only a few sites follow the obligatory task and there are reports stating the effect of the education is minimal. As a result, this research aims to determine and analyze the current state of the basic occupational safety and health training including its lesson plan and method. Furthermore, by analyzing the preliminary study on the effective instructional method, this research suggests an effective method to implement safety consciousness to the workers. An improvement plan is also suggested by supplying appropriate educational material to different workers by differentiating the characteristics and the cause of death at various work types in construction sites.

  • Over the last decade, many researchers have investigated a number of vision-based construction object detection algorithms for the purpose of construction site monitoring. However, previous methods require the ground truth labeling, which is a process of manually marking types and locations of target objects from training image data, and thus a large amount of time and effort is being wasted. To address this drawback, this paper proposes a vision-based construction object detection framework that employs an active learning technique while reducing manual labeling efforts. For the validation, the research team performed experiments using an open construction benchmark dataset. The results showed that the method was able to successfully detect construction objects that have various visual characteristics, and also indicated that it is possible to develop the high performance of an object detection model using smaller amount of training data and less iterative training steps compared to the previous approaches. The findings of this study can be used to reduce the manual labeling processes and minimize the time and costs required to build a training database.

  • This study was performed to identify the education and training characteristics and the educational performance of the incumbent. For the enterprise in the rapidly changing market environment, the human resources is an important factor to secure the market competitiveness, and the enterprise promotes the development of competence and the corporate performance through the education and training. However, in spite of such effort, the continuously increasing turnover rate and the low utilization rate of educational contents make the enterprises to hesitate the investment in the education and training. Although, the researchers are conducting lots of researches on the characteristics and the performance of the education and training, the research focusing on the characteristics and the field utilization of the education and training is not sufficient due to such reasons, Therefore, this study intended to draw the factors of education and training characteristics through existing researches and find out what impact they have actually on the utilization in business by the incumbents through the organizational commitment. In the results of this study, it was shown that the self-efficacy do not have impact on the organizational commitment, the appropriateness of instructor ability has positive (+) impact on the continuous commitment and the emotional commitment, and the work correlation has negative impact on the continuous commitment and the emotional commitment. These results seems to mean that the importance of the instructor ability and the educational program should be increased and it is intended to provide the basic data for the education-related personnel and the related enterprises.
