사람들은 항상 사건들과 접하고 그것을 지각하며 산다. 우리는 이러한 광학 흐름의 결과로 볼 수 있는 사건들을 어렵지 않게 인지한다. 문제는 사람들이 어떻게 이러한 사건들을 인지하며 광학 흐름 중 어떠한 정보가 우리로 하여금 이러한 사건들을 인지하게 만드는 지이다. 운동이론학자들은 인간은 이러한 사건들을 생산함과 동시에 지각하기 때문에 말소리 지각이나 생물학적 운동과 같은 사건들을 지각하는 것에 특별한 감각을 가지고 있다고 주장해왔다. 하지만, 직접지각 접근법 연구자들은 말소리 지각이나 생물학적 운동은 어떠한 다른 사건들을 지각하는 것과 다르지 않다고 제안했다. 이 논문의 목적은 사건지각에 관한 운동이론과 직접지각 접근법의 관점에 대해 설명하고 운동이론을 비판함으로써 이 두 이론을 비교하는 것이다. 점차 발전하고 있는 로봇공학과의 융합에 있어서 이러한 인간의 기본적인 사건 지각 능력을 먼저 이해하는 것이 중요하다.

In this paper, we propose students' perception of software education according to the type of school. So, in this study, 47373 students were surveyed about the perception of SW education, and the results of the questionnaire were analyzed according to school type, gender, school level, experience of software education and event, and duration of software education experience. As a result, students attending software education lead schools showed the highest perception about software education, followed by software education research school and general school. In gender, males were more positive than females. The level of satisfaction and effectiveness of software education in school level was higher as the school level was lower, but the perception and career area of software education was higher as the school level was higher. In addition, software training and event experience have a positive effect on students' perception of software education, and the perception of software education changes positively as the duration of software education increases.

사람들은 항상 사건들과 접하고 말소리 지각과 같은 사건을 지각하는데 별 어려움이 없다. 생물학적 운동의 지각과 마찬가지로, 말소리 지각에 대한 두 이론이 논쟁해 왔다. 이 논문의 목적은 말소리 지각에 대해 설명하고 말소리 지각에 대한 운동이론과 직접지각 이론을 비교하는 것이다. 운동이론학자들은 인간은 운동신경의 명령에 의해 말소리를 지각하고 생성해 내기 때문에 인간은 말소리 지각에 있어서 특별한 감각을 가지고 있다고 주장해 왔다. 하지만, 직접지각 이론학자들은 말소리 지각은 여느 다른 소리를 지각하는 것과 다르지 않다고 제안했다. 왜냐하면, 말소리를 지각하는 것은 다른 모든 사건을 지각하는 것과 마찬가지로 필요한 정보를 직접 탐지하면 되기 때문이다. 음성공학과의 융합에 있어서 이러한 인간의 기본적인 말소리 지각 능력을 먼저 이해하는 것이 중요하다. 따라서 이러한 말소리 지각에 대한 기본적인 이해는 인공 지능, 음성 인식 기술, 음성 인식 시스템 등에 사용될 수 있을 것으로 기대된다.

The perception of the 20 adverse events of targeted therapy for metastatic renal cell carcinoma was compared among medical professionals. Thirty-seven oncologists, 167 nurses and 79 pharmacists participated in the survey, and the response rate was 61.9%, 98.2%, 84.9%, respectively. Results showed that the most serious adverse event was GI perforation (8.83 points, 10 being the most serious), whereas the least serious was anemia (5.32 points). There were significant differences among oncologists, nurses and pharmacists especially for the moderately-serious adverse event such as wound-healing complication and lymphopenia. Adverse Events Composite Score (AECS) for each targeted therapy was calculated by multiplying adverse event incidence rate and seriousness score. Sunitinib had the highest score at 6.86 point and bevacizumab had the lowest at 2.1. Among professional groups oncologists showed the lowest AECS, whereas nurses had the highest. The gap on the perception of the adverse events among medical professionals needs to be reduced to get better outcomes of medical therapies for cancer patients.

Appreciating the aspect of modem architecture requires not only the comprehension of the nature of design and architects' ways of thinking and expression but also observers' views on buildings and their perceptive/cognitive stages. This calls for an in-depth study on the "system of phenomenological perceptions" that works as a new architectural experience system. The system of phenomenological perceptions makes it possible to specify the individual process of understanding architecture, that is, hands-on experiences, participations, feelings, perceptions, and cognition. The value of user experience and cognition has been emphasized by philosophical and aesthetical concepts as well. Therefore, in order to better appreciate the modern architecture, this study suggests theoretical consideration to "orientation and event" that are crucial elements in understanding a phenomenological view and materializing actual space formation. This offers the cognitive system with which we analyze modem architecture and comprehensive expressional methods. In other words, this study contemplates the system of phenomenological perceptions from an existential spatial perspective by structurizing the system of the orientation and the event in order to segmentalize users' current locations, potential directions, the relations with spaces, continual vie'wpoints as well as buildings' functions and interior and exterior division. The system of phenomenological perceptions helps understand and systemize modern architecture through a system based on relations between sensation, perception, cognition, sensitivity, and rationality. This creates a new cognitive system employing the concept of the orientation and the event, which is different from a normal cognitive system basing on the sense of vision. When observers appreciate space, they tend to relate the space to a certain event and to remember their experiences in it. During the process, they draw borders of the space in which the event takes place and give shape to their experiences including actions, movements, cognition and sensation. The process leads to the formation of "placeness," and here, the concept of the orientation comes in as the location and the center of the placeness. This study proves that a determined orientation coupled with individual experience and events settles the place ness; detailed elements in the cognitive system have close relations with one another; the orientation, actions, events, and places are the factors that materialize observers' architectural experience.

This study was conducted to check the cabin crew's safety perception in relation to the airline's safety climate and cabin crew's safety action and to verify that the safety perception's mediation effects. The results of the study confirmed that all three factors of the safety climate have a significant impact on safety perception, and among them, safety practice is the most significant. Accordingly, Airlines need to establish a community that enables real-time information exchange for air accidents so that the cabin crew can present real-time examples of safety-related accidents. In addition, it will be necessary to work with external safety agencies to form an active attitude for the establishment of safety procedures in order to prevent recurrence of safety problems while considering the causes of such incidents internally in the event of an airline safety accident. In addition, it was confirmed that safety training was the most significant factor to safety action, among which all three elements of the safety climate had a significant effect on safety action. Therefore, airlines need to expand practical training on aircraft to full-scale safety training to build an immediate resolution for cabin crews in the event of an air accident. In addition, safety training should be established to encourage collaboration among aviation safety-related personnel to participate in safety training together to address aviation safety from a diverse point of view. Safety perception was has a significant effect on safe action. Therefore, airlines should reinforce the airline's safety management system by checking the status of the cabin crew's safety perception extending the level of punishment to the scope of retirement or disqualification to establish a firm awareness of safety. Finally, the safety perception has demonstrated partial mediation effects in relation to the safety climate and safety action. Therefore, the airline needs to improve the duties of the cabin crew that interferes with cabin safety duties. In addition, airlines should utilize advertisements emphasizing that safety is first.

A few studies have shown that the function of fusiform face area is selectively involved in the perception of faces including a race difference. We investigated the neural substrates of the face-selective region called fusiform face area In the ventral occipital-temporal cortex and same-race memory superiority In the fusiform face area by the event-related fMRI. In our fMRI study, twelve healthy subjects (Oriental-Korean) performed the implicit distinction of the race while they consciously made familiar-judgments, regardless of whether they considered a face as Oriental-Korean or European-American. In the race distinction as an implicit task, the fusiform face areas (FFA) and the right parahippocampal gyrus had a greater response to the presentation of Oriental-Korean than European-American faces, but in the consciously race distinction between Oriental-Korean and European-American faces, any significant difference in the FFA was not observed. These results suggest that different activation in the fusiform regions and right parahippocampal gyrus resulting from same-race memory superiority could be implicitly taken place by the physiological processes of face recognition.

Congestion in WSN increases energy dissipation rates of sensor nodes as well as loss of packets and thereby hinders fair and reliable event detections. We find that one of the key reasons of congestion in WSN is allowing sensing nodes to transfer as many packets as possible. This is due to the use of CSMA/CA that gives opportunistic media access control. In this paper, we propose an energy efficient congestion avoidance protocol that includes source count based hierarchical and load adaptive medium access control. Our proposed mechanism ensures load adaptive media access to the nodes and thus achieves fairness in event detection. The results of simulation show our scheme exhibits more than 90% delivery ratio with retry limit 1, even under bursty traffic condition which is good enough for reliable event perception.

Recently, deep recurrent neural networks have achieved great success in various machine learning tasks, and have also been applied for sound event detection. The detection of temporally overlapping sound events in realistic environments is much more challenging than in monophonic detection problems. In this paper, we present an approach to improve the accuracy of polyphonic sound event detection in multichannel audio based on gated recurrent neural networks in combination with auditory spectral features. In the proposed method, human hearing perception-based spatial and spectral-domain noise-reduced harmonic features are extracted from multichannel audio and used as high-resolution spectral inputs to train gated recurrent neural networks. This provides a fast and stable convergence rate compared to long short-term memory recurrent neural networks. Our evaluation reveals that the proposed method outperforms the conventional approaches.

As the perception of sports activities changes positively, the desire and popularity for sports activities are rapidly increasing. Therefore, the popularity of sporting events is also increasing. Previous studies on sporting events have focused only on research in the field of social sciences. Therefore, in this study, in order to increase customer satisfaction and customer loyalty of sports event visitors, they were classified into challenge factors, competition factors, achievement factors, and relationship factors, and their effects on satisfaction and loyalty were studied and analyzed. And based on the research design model and empirical analysis, a user-based sports event matching system was proposed.
