미래 핵심인 SW산업의 국제 경쟁력 확보를 위하여, SW 분야의 세계적인 기술변화에 대응하고 향후 SW 산업의 분석 및 설계를 주도할 아키텍트 수준의 SW 기술 인력 양성이 요구된다. 그러나 현재의 상황은 일정 수준의 경력에 따른 SW 기술 인력이 일반관리자로 전직하는 경향을 보이고 있다. 이러한 현실을 해결하고 SW 기술 인력의 질적 수준을 제고하기 위해서 국내 SW 기술 인력의 체계적이고 효과적인 성장방향을 제시하는 것이 필요하다. 따라서 본 논문에서는 국내 SW 기술 인력의 체계적이고 효과적인 성장방향을 제시하면서, 고급 SW 분석/설계 인력의 경력 경로를 제시하며 이를 실현할 수 있는 방만을 제시하고자 한다.

While human error has been one of the main technical issues from the early era of human factors engineering, it still remains hot and somewhat vague due to the various types of the concepts and words on human errors in practice. There may be some technical limitations hindering human error prevention activities. This paper introduces the human error activities described in the papers if this issue of ESK Journal according to a few criteria proposed for more effective technical review. And two basic technical issues are discussed on the concepts, perspectives, and classifications about human errors. Each activity shows its own artifacts associated with the safety purpose and the nature of the industry. This paper also provides a set of new technical bases proposed for a more effective management of human errors by considering the dependability, representativeness, and structuredness of human errors. Additionally, this paper includes some new challenges over the current prevention-oriented activities; positive utilizations of human errors to training/education, advertisements, fun and entertainments, and nudges.

The mass attenuation coefficient is the primary physical parameter to model narrow beam gamma-ray attenuation. A new machine learning based approach is proposed to model gamma-ray shielding behavior of composites alternative to theoretical calculations. Two fuzzy logic algorithms and a neural network algorithm were trained and tested with different mixture ratios of vanadium slag/epoxy resin/antimony in the 0.05 MeV-2 MeV energy range. Two of the algorithms showed excellent agreement with testing data after optimizing adjustable parameters, with root mean squared error (RMSE) values down to 0.0001. Those results are remarkable because mass attenuation coefficients are often presented with four significant figures. Different training data sizes were tried to determine the least number of data points required to train sufficient models. Data set size more than 1000 is seen to be required to model in above 0.05 MeV energy. Below this energy, more data points with finer energy resolution might be required. Neuro-fuzzy models were three times faster to train than neural network models, while neural network models depicted low RMSE. Fuzzy logic algorithms are overlooked in complex function approximation, yet grid partitioned fuzzy algorithms showed excellent calculation efficiency and good convergence in predicting mass attenuation coefficient.

The purpose of this study is to develop an engineer competency model using Analytical Hierarchy Process (AHP) to improve the national technical qualification system. Korea has managed technical human resources at the government level through the operation of a national technical qualification system that certifies engineers with national certificates or technical grades by laws. However, there have been increasing concerns that the government system is separated from global standards and does not reflect an engineer's comprehensive capabilities. For these reasons, the new architecture of the system has been continuously discussed and becomes a major policy issue of the Korean government. For the development of the engineer competency model, domestic and global models were separately structured using 554 valid questionnaires with a consistency ratio (CR) of 0.1 or less. The relative importance of engineer competency factors in a domestic model was career (0.383), qualification (0.253), academic degree (0.195), and job training (0.169) whereas the order in the global model was career (0.308), global ability (0.237), job training (0.175), domestic qualification (0.147), and academic degree (0.134). The results of AHP analysis indicated that the evaluation factors and methods recognized by engineers were different from a current government model focusing on domestic qualifications. There was also perceptual difference in the importance of engineer evaluation factors between groups depending on the type of organizations and markets. This means that it is necessary to reflect the characteristics of organizations and markets when evaluating engineer competency. Based on AHP analysis and literature reviews, this paper discussed how to develop a new engineer competency index (ECI) and presented two effective index models verified by simulation test using 59,721 engineers' information. Lastly, the paper discussed major findings of our empirical research and proposed policy alternatives for the improvement of a national engineer qualification system. The paper contributes to the management of technical human resources since it provides quantitative competency models that are objectively developed by reflecting market recognition and can be effectively used by the policy makers or firms.

Purpose: Microsurgery is an essential technique in plastic and reconstructive surgery. However, microsurgical suturing and handling of the instrument are difficult for beginners, and who requires a steep learning curve. Therefore, methods for improving the technical skill are needed. The authors describe the value of a small stereoscopic microscope as a training tool. Materials and Methods: A small stereoscopic microscope was used to help improve the microsurgical skill. Monofilament 10-0 Nylon and a surgical rubber globe were used as a suture material and education material, respectively Result: Stereoscopic view of the operation field was obtained and basic microsurgical suture was possible. Conclusion: The stereoscopic microscope is an effective training tool for beginners of microsurgery with benefits in cost and usefulness in small place.

Currently, flight training is not only a technical instruction that teaches maneuvering operations, but has expertise equal to that of general disciplines. Therefore, flight instructors must have academic knowledge and flight skills. As flight instructors are the first teacher in flight training for students who have never experienced actual flight control, the behavior of flight instructors will affect the students' flight education. Therefore, the influence of flight instructors for students are quite large compared to other educational institutions. In this study, the factors of instructional behavior were determined, and the actual state of instructional behavior of flight instructors were confirmed through students' survey. Improvements were derived to solve the problems identified in the survey results. For the follow-up analysis, improvements were applied to the flight instructors for 8 months, and then re-question was conducted to the same students who responded to the first questionnaire to find out the difference in results before and after through a paired t-test.

The aim of 2000s' technical college is to cultivate technicians who have their own specialities. This means that the technician's duty is not to fit themselves to the wide fields of work, but to strengthen the competitiveness ensuring the4ir speciality in the society that is based on knowledge. The educational substances of the college attach more importance to a design, but the Interior Architecture works and official situations that amount to almost Interior Architecture business in these modern days are focalized on a field construction rather than desigv. $\ulcorner$It is not able to ensure the speciality in the project performing a plan to design and a construct management at the same time. And when they perform their duties, even any beginners graduated from technical college can't direct or guide constructors$\lrcorner$There the construction subjects of technical college should consist of practical education centering around items that is condensed from research data $\ulcorner$they should know how to set up and concrete the treatments$\lrcorner$
