This article examines the effect of CEO's political connections on firm performance in Chinese private firms. Following the upper echelon theory and human capital theory, CEO's personal characteristics affect the strategic decision-making of the firm, and it is also firm-specific advantages that work as the human capital for the sustainable growth of the firm. In this regard, this article tries to empirically confirm whether CEO's political connections have positive effects on firm performance as the firm's human capital by dividing the Chinese local governments, which is a direct subject of political connections hierarchically. In addition, this research examines the mediating effects of government subsidies between political connections and firm performance. To verify these questions, we use a sample of 9,849 observations of 1,451 private firms listed on the Shanghai and Shenzhen stock exchanges from 2008 to 2016, the results show that the CEO's political connections are positively related to firm performance. Moreover, we find that only political connections with the provincial local government had a positive effect on firm performance. It indicates that values and influences of human capital held by CEOs only affect when they are related to the highest local government. Finally, when CEOs have political connections with city-level, it shows complete mediating effect. It provides empirical evidence to find that CEO's political connections affect firm performance as the results of non-market strategic of firms.

Due to the need of data for a Human Reliability Analysis (HRA), a number of data collection efforts have been undertaken in several different organizations. As a part of this effort, a human error analysis that focused on a set of simulator records on a Steam Generator Tube Rupture (SGTR) scenario was performed by using the Human Event Repository and Analysis (HERA) system. This paper summarizes the process and results of the HERA analysis, including discussions about the usability of the HERA system for a human error analysis of simulator data. Five simulated records of an SGTR scenario were analyzed with the HERA analysis process in order to scrutinize the causes and mechanisms of the human related events. From this study, the authors confirmed that the HERA was a serviceable system that can analyze human performance qualitatively from simulator data. It was possible to identify the human related events in the simulator data that affected the system safety not only negatively but also positively. It was also possible to scrutinize the Performance Shaping Factors (PSFs) and the relevant contributory factors with regard to each identified human event.

Motivation of human individuals to perform on intellectual tasks can be hampered by identity threat from intellectual machines. A laboratory experiment examined whether individuals' performance loss on intellectual tasks appears under human identity threat. Additionally, by affirming alternative attributes of human identity, researchers checked whether group-affirmation alleviate the performance loss on intellectual tasks. This research predicted that under high social identity threat, individuals' performance loss on the intellectual tasks would be moderated by valuing alternative attributes of human identity. Experiment shows that when social identity threat is increased, human individuals affirmed alternative human attributes show higher performance on intellectual tasks than individuals non-affirmed. This effect of human-group level affirmation on performance loss did not appear in the condition of low social identity threat. Theoretical and practical implications were discussed.

Extracting primitives from imagery plays an important task in visual information processing since the primitives provide useful information about characteristics of the objects and patterns. The human visual system utilizes features without difficulty for image interpretation, scene analysis and object recognition. However, to extract and to analyze feature are difficult processing. The ultimate goal of digital image processing is to extract information and reconstruct objects automatically. The objective of this study is to develop robust method to achieve the goal of the image processing. In this study, an adaptive strategy was developed by implementing Gabor filters in order to extract feature information and to segment images. The Gabor filters are conceived as hypothetical structures of the retinal receptive fields in human vision system. Therefore, to develop a method which resembles the performance of human visual perception is possible using the Gabor filters. A method to compute appropriate parameters of the Gabor filters without human visual inspection is proposed. The entire framework is based on the theory of human visual perception. Digital images were used to evaluate the performance of the proposed strategy. The results show that the proposed adaptive approach improves performance of the Gabor filters for feature extraction and segmentation.

Human sensibility ergonomics is applied to evaluation of dynamic performance of a vehicle driving simulator. Vehicle, driving environment, and human perception models are constructed and integrated. Driving simulations are carried out based on these models. This study defines a set verbal expressions collected and investigates which are the most appropriate for describing the fidelity of translational and angular accelerations of the driving simulator. An statistical analysis is uscd to find correlation between the ergonomic sensibility and the cut-off frequency of the washout algorithm. This study suggests a methodology to obtain an ergonomic database which can be used for the performance evaluation of dynamic environments.

The purpose of this study was to assess the sanitary education performance for employee through school foodservice dietitians in Jeonju area. Questionaires were distributed to 67 dietitians of school foodservice. The statistical analysis of data was completed using SPSS 10.0 program. The results were summarized as follows: 47.8% of dietitians were $31{\sim}35$ years old and 73.1% were regular employee. 37.3% had a dietitian career less $5{\sim}10$ years old. Most dietitians(74.6%) provided verbal training to the school foodservice employees at least once every month. This training included details of personal, facility and food processing hygiene, food poisoning and microorganism. Because of 'missing time' had 65.7% of dietitian a problem to conduct the sanitary training. The working experience and academic background of dietitians influenced on the item of sanitary training, not on the frequency of training.

For a sophisticated humanoid that explores and learns its environment and interacts with humans, anthropomorphic physical behavior is much desired. The human vision system orients each eye with three-degree-of-freedom (3-DOF) in the directions of horizontal, vertical and torsional axes. Thus, in order to accurately replicate human vision system, it is imperative to have a simulator with 3-DOF end-effector. We present a 3-DOF anthropomorphic oculomotor system that reproduces realistic human eye movements for human-sized humanoid applications. The parallel link architecture of the oculomotor system is sized and designed to match the performance capabilities of the human vision. In this paper, a biologically-inspired mechanical design and the structural kinematics of the prototype are described in detail. The motility of the prototype in each axis of rotation was replicated through computer simulation, while performance tests comparable to human eye movements were recorded.
