The purpose of this study was to analyze the effects of human resource development on the job satisfaction and wage among employed workers. A sample of 3,578 employed workers was selected from Korea Labor Panel Data. For data analysis, t-test and multiple regression were used. The major findings were as follows: First, the employed workers who had experiences of human resource development had more certificates of job-related qualification, more employed in government-invested organization or foreign company regularly than the counterpart. Second, the employed workers' wage was affected by gender, age, educational attainment, as well as whether they had experiences of human resource development. Third, the factors that influence employed workers' job satisfaction were gender, age, educational attainment, job regularity, having certificate of job-related qualification or not, and having experiences of human resource development or not. From the findings, it can be concluded that the employed workers' wage and job satisfaction were improved by the human resource development.

Since human decision making behavior is likely to follow nonlinear strategy, it is conjectured that the human decision making behavior can be modeled better by nonlinear models than by linear models. All that linear models can do is to approximate rather than model the decision behavior. This study attempts to test this conjecture by analyzing human decision making behavior and combining the results of the analysis with predictive performance of both linear models and nonlinear models. In this way, this study can examine the relationship between the predictive performance of models and the existence of valid nonlinear strategy in decision making behavior. This study finds that the existence of nonlinear strategy in decision making behavior is highly correlated with the validity of the decision (or the human experts). The second finding concerns the significant correlations between the model performance and the existence of valid nonlinear strategy which is detected by Lens Model. The third finding is that as stronger the valid nonlinear strategy becomes, the better nonlinear models predict significantly than linear models. The results of this study bring an important concept, validity of nonlinear strategy, to modeling human experts. The inclusion of the concept indicates that the prior analysis of human judgement may lead to the selection of proper modeling algorithm. In addition, lens Model Analysis is proved to be useful in examining the valid nonlinearity in human decision behavior.

Objective: This paper describes an analysis of electroencephalography(EEG) signals to identify human errors during using digital devices in nuclear power plants(NPPs). Background: The application of an advanced main control room(MCR) has accompanied with lots of changes in different forms and features by virtue of new digital technologies. The characteristics of these digital technologies and devices provide several opportunities for the use of interface management. It can integrate into a compact single workstation in an advanced MCR, allowing workers to operate the plant with minimum physical burden under any operating condition. However these devices may introduce new types of human errors, and thus we need a means to assess and prevent such errors especially those related to digital devices. Method/Conclusion: The EEG data are relatively objective, and thus we introduce several measures to EEG analysis for obtaining the feasibility of human error identification. Application: This study may support to ensure the safety when applying digital devices in NPPs.

The objective of this study is to develop short-term prevention measures for minimizing possible human error in nuclear power facilities. To accomplish this objective, a group of subject matter experts (SMEs) were formed, which is consisting of those from regulatory bodies, academia, industries and research institutes. Prevention measures were established for urgent execution in nuclear power facilities on a short-term basis. This study suggests short-term measures for reducing human error on three different areas; (1) strengthening worker management, (2) enhancing workplace environments and working methods, and (3) improving the technologies regulating human factors. Under the leadership of the Ministry of Science and Technology, these short-term measures will be pursued and implemented systematically by utility and regulatory agencies. The details of prevention measures are presented and discussed.

Rail human factors research has grown rapidly in both quantity and quality of output over the past few years. Human factors, also, still plays a significant part in many railway accidents. In this paper we review categorized performance shaping factors of human errors associated with railway accidents within and out of the country. This paper deals with the selection of the important performance shaping factors under accident management situations in railway for use in the assessment of human errors. The purpose of this study is to classify which human error would be selected for accident analysis. Therefore, the classification of human errors suggested in this study may be useful to enhance the Korean railway system safety.

The bleaching is one of the worst factors which leads to the damage of the human hair. The cuticle of the human hair is injured by the alkali that is one of the chief ingredients of a bleaching agent. The alkali component of the bleaching solution chemically reacts with human hair, reducing the tenacity and dissolving the cuticle layer. The purpose of this study is to examine the effects of bleaching time and temperature on the physical properties and morphology. The results were as follows. 1. The stress-strain curves for human hair indicated the three distinct regions, such as Hookean region, Yield region and post-Yield region. The tenacity of hair is reduced gradually with an increase of bleaching time. Under these same conditions, elongation of the hair increased. 2. The greatest drop in tenacity for hair occured between $40^{\circ}C$ and $60^{\circ}C$ of bleaching temperature. 3. Compared with the virgin hair, bleached hair showed a slower rate of weight reduction in the TGA thermogram. The rate decreased gradually as the bleaching time and temperature increased. 4. As the bleaching conditions reached time and temperature extremes, the human hair cuticle became more damaged. The cuticle layers seemed to have dissolved, as seen in the SEM photographs.

데이터 기반 기계번역의 성공여부는 대량의 데이터를 단기간에 구축하는 방법과, 또 구축된 데이터에 대한 효과적인 관리 방법이 좌우한다고 할 수 있다. 대표적인 데이터 기반 기계번역 방법론인 예제 기반 기계번역 방식이나 패턴 기반 기계번역 방식에서는 최소한의 학습 내지는 학습과정 없이 데이터를 구축하는 데에 연구가 중점적으로 이루어져왔으나, 데이터의 관리 문제에 대해서는 많은 연구가 이루어지지 못하였다. 그러나 데이터의 확장 못지않게 데이터의 효율적인 관리도 데이터 기반 기계번역 시스템의 개발에서 매우 중요하다. 이 논문에서는 사/피동 링크 등을 이용하여 사전을 재구성하는 것이 데이터의 일관성과 관리성을 향상시키고, 이론적인 면에서는 정보 기술상의 잉여성을 줄인다는 점을 보인다. 또한 이러한 정보에 기반하여 기구축된 동사구 패턴으로부터 대역어 정보를 이용하여 새로운 패턴을 만들어내는 방법론도 제시한다.

Social infrastructures have been built when the growth of economy in Korea significantly increases in 1960s. Nowadays, these infrastructures have been aged with an inappropriate maintenance and management and the citizens have rare recognition for human disasters. In addition, the government has law or regulations responding to human disasters but these are not complementary. Since these human disasters have been issued as social problems and have induced social and economic loss, the improvement schemes for human disasters are currently being demanded. In this study, the case histories of damages and improvement schemes with respect to the types of damages for human disasters are comprehensively investigated.

In this study, a system to increase the expressiveness of existing standard terminology using three-dimensional (3D) data is designed. We analyze the existing medical terminology system by searching the reference literature and perform an expert group focus survey. A human body image is generated using a 3D modeling tool. Then, the anatomical position of the human body is mapped to the 3D coordinates' identification (ID) and metadata. We define the term to represent the 3D human body position in a total of 12 categories, including semantic terminology entity and semantic disorder. The Blender and 3ds Max programs are used to create the 3D model from medical imaging data. The generated 3D human body model is expressed by the ID of the coordinate type (x, y, and z axes) based on the anatomical position and mapped to the semantic entity including the meaning. We propose a system of standard terminology enabling integration and utilization of the 3D human body model, coordinates (ID), and metadata. In the future, through cooperation with the Electronic Health Record system, we will contribute to clinical research to generate higher-quality big data.

Purpose - The purpose of this study was to explores how CEO general human capital, one of the most critical issues in recent research, affects compensation schemes. Design/methodology/approach - This study collected the CEOs of S&P500 companies from 2001 to 2009 and contains 4,155 CEO-firm-year observations and 704 different CEOs. Findings - First, only contingent bonus is affected by general human capital and reputation. Second, the career concerns of CEOs are relevant, especially when explaining CEO tenure. Third, we offer an alternative view of what determines the level of cash compensation schemes and the factors that affect the running of a firm. Fourth, we also suggest that the increase in general human capital can be explained by the increase in its relative importance in managing a modern firm. Overall, the results of this study do not only contribute to academics but also important to boards and shareholders. Research implications or Originality - This study intends to fill the gap in the extant literature by examining the relationship between general human capital and compensation schemes.First, we add to the compensation literature by arguing that a cash compensation scheme is efficient for generalist CEOs. We break down CEO cash compensation schemes into fixed and contingent bonus compensation and investigate whether general human capital differentially affects CEO cash compensation schemes, and thus, the sensitivity to unequal pay for human capital. Second, we contribute to the reputation literature by arguing that CEO perceived reputation also affects CEO compensation schemes.
