Visual inspection is regarded as one of the critical activities for quality control in a manufacturing company. it is thus important to improve the performance of detecting a defective part or product. There are three probable working modes for visual inspection: fully automatic (by automatic machines), fully manual (by human operators), and semi-automatic (by collaboration between human operators and automatic machines). Most of the current studies on visual inspection have been focused on the improvement of automatic detection performance by developing a better automatic machine using computer vision technologies. However, there are still a range of situations where human operators should conduct visual inspection with/without automatic machines. In this situation, human operators'performance of visual inspection is significant to the successful quality control. However, visual inspection of components assembled into a mobile camera module belongs to those situations. This study aims to investigate human performance issues in visual inspection of the components, paying more attention to human errors. For this, Abstraction Hierarchy-based work domain modeling method was applied to examine a range of direct or indirect factors related to human errors and their relationships in the visual inspection of the components. Although this study was conducted in the context of manufacturing mobile camera modules, the proposed method would be easily generalized into other industries.

This study with emphasis on protecting human rights of people with mental disorder investigated human rights awareness among mental health workers and identify factors affecting their awareness. Questionnaires were sent out to employees working in mental health facilities in all parts of the country and of those 1094 were used to analyze. According to the analysis, employees' human rights awareness was ranked highest in the areas of occupational therapy and lowest in the areas of admission and discharge. Those who are women, aged between 30 and 40, highly educated, with long tenure, employed as social workers and working at rehabilitation programs presented high awareness of human rights so did employees with license in mental health and training experience in human rights. The result also presented negative correlation between employees' human rights awareness and their prejudice against people with mental disorder. Through this study, guidelines will be set up to help employees acknowledge the importance of human rights awareness and raise their awareness to promote and practice human rights of people with mental disorder.

The purpose of this study is to analyze the effect of internationalized human capital on SME's export performance and to examine the moderating effects of export experience and export market diversification of SMEs that can affect the relationship between internationalized human capital and export performance of SMEs. The results of empirical analysis of 150 small and medium-sized enterprises located in Jeonnam province are as follows. First, the internationalized human capital of SMEs was found to have a positive (+) effect on export performance. Second, as a result of empirically analyzing the moderating effect of internationalized human capital on export performance, the export experience of SMEs was found to have a negative (-) moderating effect on the relationship between internationalized human capital and export performance of SMEs, and the export market diversification had a negative (-) moderating effect on the relationship between internationalized human capital and export performance of SMEs. This study provides meaningful theoretical implications in that this study identified the role of human capital by analyzing the relationship between internationalized human capital as an important source of competitive advantage of SMEs and export performance.

Human state in human-machine systems highly affects the overall system performance, and should be detected and monitored. Physiological cues are essential indicators of human state and useful for the purpose of monitoring. The study presented in this paper was focused on developing a bio-inspired sensing system, i.e., Nano-Skin, to non-intrusively measure physiological cues on human-machine contact surfaces to detect human state. The paper is presented in three parts. The first part is to analyze the relationship between human state and physiological cues, and to introduce the conceptual design of Nano-Skin. Generally, heart rate, skin conductance, skin temperature, operating force, blood alcohol concentration, sweat rate, and electromyography are closely related with human state. They can be measured through human-machine contact surfaces using Nano-Skin. The second part is to discuss the technologies for skin temperature measurement. The third part is to introduce the design and manufacture of the Nano-Skin for skin temperature measurement. Experiments were performed to verify the performance of the Nano-Skin in temperature measurement. Overall, the study concludes that Nano-Skin is a promising product for measuring physiological cues on human-machine contact surfaces to detect human state.

In the shipping industry, it is well known that around 80 % or more of all marine accidents are caused fully or at least in part by human error. In this regard, the International Maritime Organization (IMO) stated that the study of human factors would be important for improving maritime safety. Consequently, the IMO adopted the Casualty Investigation Code, including guidelines to assist investigators in the implementation of the Code, to prevent similar accidents occurring again in the future. In this paper, a process of the human factors investigation is proposed to provide investigators with a guide for determining the occurrence sequence of marine accidents, to identify and classify human error-inducing underlying factors, and to develop safety actions that can manage the risk of marine accidents. Also, an application of these investigation procedures to a collision accident is provided as a case study This is done to verify the applicability of the proposed human factors investigation procedures. The proposed human factors investigation process provides a systematic approach and consists of 3 steps: 'Step 1: collect data & determine occurrence sequence' using the SHEL model and the cognitive process model; 'Step 2: identify and classify underlying human factors' using the Maritime-Human Factor Analysis and Classification System (M-HFACS) model; and 'Step 3: develop safety actions,' using the causal chains. The case study shows that the proposed human factors investigation process is capable of identifying the underlying factors and indeveloping safety actions to prevent similar accidents from occurring.
