  • The snake detection theory posits that, due to competition with snakes, the primate visual system has been evolved to detect camouflaged snakes. Specifically, one of its hypotheses states that the subcortical visual pathway mainly consisting of koniocellular cells enables humans to automatically detect the threat of snakes without consuming mental resources. Here we tested the hypothesis by comparing human participants' responses to snakes with those to fearful faces and flowers. Participants viewed either original images or converted ones, which lacked the differences in color, luminance, contrast, and spatial frequency energies between categories. While participants in Experiment 1 produced valence and arousal ratings to each image, those in Experiment 2 detected target images in the breaking continuous flash suppression (bCFS) paradigm. As a result, visual factors influenced the responses to snakes most strongly. After minimizing visual differences, snakes were rated as being less negative and less arousing, and detected more slowly from suppression. In contrast, the images of the other categories were less affected by image conversion. In particular, fearful faces were rated as greater threats and detected more quickly than other categories. In addition, for snakes, changes in arousal ratings and those in bCFS response times were negatively correlated: Those snake images, the arousal ratings of which decreased, produced increased detection latency. These findings suggest that the influence of snakes on human responses to threat is limited relative to fearful faces, and that detection responses in bCFS share common processing mechanisms with conscious ratings. In conclusion, the current study calls into question the assumption that snake detection in humans is a product of unconscious subcortical visual processing.

  • Recruiting and maintaining capable IS personnel is crucial to on-time application developments and information services that can gear to corporate strategic planning and to achieve corporate goals and objectives. A shortage of fine IS staff has been always a threat to providing satisfactory IS services and a constraint that holds companies back to expand further and operate more efficiently. Therefore, it is necessary to understand factors that satisfy IS personnel and then restrain them not to leave their current job positions. However, little study has been done about what these factors are and how these factors are related to the turnover intention each other especially using domestic data. Therefore, this study suggested a structural turnover intention model and investigated relationships among the selected factors including demographic variables, career-related variables, job satisfaction, career satisfaction, organizational commitment and turnover intentions. Major findings are: i) overall, career-related variables, job satisfaction and organizational commitment significantly determine the turnover intention, ii) contrary to the U.S. studies, our IS people tend to show lower organizational commitment as they become older and get more experience, and iii) contrary to the U.S.'s findings, career-related variables are negatively related to organizational commitment. Implications and discussions of these findings are also described.

  • Aviation industry is growing rapidly, and this growth is expected to continue. However, aircraft accident rate is still high, and 65 percent of accidents occur during landing phase due to unstable approach. Therefore, this research analyzed causes and countermeasures of unstable approach. In order to derive countermeasures, this study selected P International Airport as an example case. In addition, this research analyzed A airline's FOQA data, regional Standard Operating Procedures, and 5 years of environmental factors to identified correlation of those contributing factors. In conclusion, his research concluded following results. First of all, because of P International Airport's geological features, pilots are required to conduct Circling Approach, and this advanced maneuver increases workload at the final stage of flight. Secondarily, meteorological factors such as crosswind, seasonal rain front, local visibility contributes unstable approach. Lastly, these geological and meteorological factors are interrelated, and this uncommon environment can decrease circumstantial judgement ability of pilots and jeopardize aviation safety. As a consequence, it is recommended to reinforce the Crew Resource Management and Threat & Error Management systems so that pilots can perceive identical safety target.

  • Now a day, Information and its related system has been more important in our competitive environment. In this situation, there is also an important thing that we must take into consideration, that's the employer's resistance. Until now we have little material concerning the issue, user's resistance. Owing to that, it's a little hard to study the user's resistance against the IS. Dealing with the resistance effectively helps companies save a great deal of cost and build the information system successfully. This paper takes the Markus's theories about user's resistance. According to the theories, there are three keys theories affecting resistance. To sum this, people-oriented theory, system-oriented theory and Interaction theory. To complement the theories, this paper includes another theories related with resistance and takes total seven factors causing user's resistance. Among these seven factors, four factors have a meaningful effect on the user's resistance, that is, Self-efficacy, System Complexity, Threat of the one's status and politics and System Staff's service quality. Managers and system-related company should keep it in mind very carefully, and I hope they make the best use of the result of this study.

  • Methicillin-resistant Staphylococcus aureus (MRSA) is a bacterial pathogen capable of causing human diseases, such as soft tissue infection, bacteremia, endocarditis, toxic shock syndrome, pneumonia, and sepsis. Although the incidence rate of diseases caused by MRSA has declined in recent years, these diseases still pose a clinical threat due to their consistently high morbidity and mortality rates. However, the role of virulence factors in staphylococcal infections remains incompletely understood. Methicillin resistance, which confers resistance to all β-lactam antibiotics in cellular islets, is mediated by the mecA gene in the staphylococcal cassette chromosome mec (SCCmec). Differences in SCCmec types and differences in their sizes and structures serve epidemiological purposes and are used to differentiate between hospital-associated (HA)-MRSA and community-associated (CA)-MRSA. Some virulence factors of S. aureus are also providing a distinction between HA-MRSA and CA-MRSA. These factors vary depending on the presence of toxins, adhesion, immune evasion, and other virulence determinants. In this review, we summarized an overview of MRSA such as resistance mechanisms, SCCmec types, HA- and CA-MRSA, and virulence factors that enhance pathogenicity or MRSA epidemiology, transmission, and genetic diversity.

  • The purpose of the present study is to prepare the conservation category to establish the Natural Ecosystem Conservation Area(NECA) in Korea. The authors prepared the conservation category for the NECA based on the previous relevant papers and reports. This draft of conservation category was examined by way of the case study. From this, the possible factors are introduced to prepare the final conservation category that can be applied directly in Korean situation for the conservation of natural areas. The present conservation category was prepared based on the possible data, while some factors of which do not possess the adequate raw data at the moment was removed. According to the reference analyses from the previous conservation categories reported in order to prepare the conservation category in the NECA, a total of 27 factors was assessed; 21 for rarity and 15 fur utility and diversity, 13 far size, for both naturalness and human influence, 13 for typicalness 12 and 10 for fragility. From the literature reviews, the categories which quantitatively assessed was 13: 9 for rarity, 8 far human influence, and 5 for size. From the 27 conservation categories assessed, the factors such as rarity, taxonomic distinctiveness and threat was regarded as applicable to the Korean situation. Furthermore, the criteria such as use could be applied further when this is supported by the augmentative research and field studies.
