인간의 지각은 외부환경을 객관적으로 반영하기 보다는 다양한 요인들에 의해 영향을 받은 결과이다. 이 요인들 중 행동-특정 지각은 환경에 대한 행위가능성에 의해 지각이 달라지는 현상이다. 기존 연구들은 행동-특정 지각이 과제를 수행하는 중에 발생하는지 아니면 수행 후 결과에 대한 지식 혹은 기억왜곡에 의한 것인지에 대해 상충된 결과를 보고하였다. 본 연구에서는 행동-특정 지각이 언제 발생하는지 확인하기 위해 다트를 사용하여 세 개의 실험을 실시하였다. 참가자들은 일정한 거리에서 다트를 수행하였으며 각 시행 후 지각된 표적의 크기를 응답지에 보고하였다. 그 결과 실험 1, 2에서 참가자들은 다트를 실패했을 때 보다 성공했을 때 표적을 더 크게 지각하였으며, 그 효과는 수행 후 표적을 볼 수 없을 때 더 강하게 발생하였다. 그러나 참가자들이 자신의 수행결과에 대해 알 수 있었기 때문에 응답에서 편파가 발생했을 가능성이 있었다. 이 가능성을 제거한 실험 3에서도 행동-특정 지각이 발생하였으며, 따라서 행동-특정 지각은 과제수행 후가 아닌 과제를 수행하는 동안 발생한다는 결론을 내릴 수 있었다.

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.

공간 지각은 일반적으로 물체(형태)를 인식하는 능력에 대한 문제로 여겨진다. 대안적으로, 형태 지각 연구는 시각 공간의 기하학에 관한 논의에 기여한다. 이러한 공간의 기하학은 일반적으로 유클리드가 아닌, 타원, 유사성, 또는 아핀(affine) 기하학으로 알려져 왔다. 다시 말해, 많은 형태 지각 연구들에서 보여 왔듯, 공간은 변형된 기하학으로 지각된다. 이 논문의 목적은 지각된 형태와 시각적으로 유도되는 행동과 관련된 시각 공간의 기하학에 대한 이해를 돕기 위함이다. 따라서 지각과 행위의 관계에 대해 설명하고 있는 두 이론을 비교해 본다. 제한된 인지와 더 나아가서, 인공 지능 연구와의 융합에 있어서 이러한 인간의 기본적인 공간 지각 능력과 시각적으로 유도되는 행위를 먼저 이해하는 것이 중요하다.

This study was to examine home economics (HE) teachers' and the 1st-grade students' needs perception toward the purposes of HE education in middle school which has been practced since 1995 for both male and female students. This study, attempted (1) to analyze needs priority among the educational purposes of HE subject in relation to three systems of actions; (2) to compare differences between HE teachers' and students' perception concerning the degree of importance and achievement of the educational purposes of HE subject: and (3) to examine what they conceive as the problems In the current HE education. The survey was conducted with the samples of 600 1st-grade middle school students and 101 middle school HE teachers during the period of February-March 1996. The questionnaire used in this study was a modified version which had already been developed along with the 6th HE curriculum. For data analyses, SAS program was utilized to get Means and to perform both discrepancy test and t-test. The findings of this study were summarized as follows: first, with respect to each group's perception of the importance of the purposes related to three systems of action, HE teachers emphasized the importance of the purposes related to emancipatory action, while students placed more emphasis on the purposes related to technical action. Second, in terms of the degree of achievement, students had more positive perception on the degree of achievement of the purposes related to technical action than HE teachers did. Both groups marked low level of recognition on the degree of achievement of the purposes related to emancipatory action. Third, with respect to needs priority, HE teachers placed the first priority on emancipatory action, the second on technical action, and the last on communicative action: in the case of students, the first priority was on technical action, the second on communicative action, and the last on emancipatory action. In addition, the analysis of the opinions on the 6th curriculum revealed that most respondents found it necessary to secure adequate amount of classes for HE education. Also they shared the recongnition that HE curriculum should be renovated into the one which would fully appreciate the purposes of HE education from the perspective of the practical concerns of action which are distinct from the functional and technical concerns of passive learning. The findings of this study can serve as basic data for establishing the new purposes of HE education which put more emphasis on the purposes related to emancipatory action: as well as for developing an enhanced curriculum and reinforcing the identity of HE education.

The purpose of this study was to estimate the relationships between dietary factors and the stress perception levels of College students. A survey was conducted in June, 2010, targeting 332 college students in Gwangju. General environmental factors, stress perception levels, dietary behaviors, and dietary action guide performance of the subjects were evaluated by questionnaire, and food intakes was determined by the 24-hour recall method. The results are summarized as follows.: The score of frequency experiencing was $45.1{\pm}16.9$ for male students, and $47.0{\pm}16.7$ for female students. The importance scores were $50.8{\pm}18.5$ for males, and $53.3{\pm}18.7$ for females. The total score for dietary action guide performance was $39.6{\pm}7.2$ for males and $40.6{\pm}6.5$ for females. Nutrient intake levels were evaluated based on dietary reference intake (DRI), revealing energy intakes to be 68.5% EER in males and 73.9% in females. The mean intakes of nutrient were 54.2% RI for calcium, 73.6% RI for riboflavin, and 51.2% RI for vitamin C but 203.6% AI for sodium, which indicates an imbalance in nutrient intake. Analysis of the correlations between stress perception levels and dietary factors, scholarship achievements, financial problems, future problems, value senses, and family relationships revealed significant correlations with general environment factors, dietary behaviors, Dietary action guide performance, and nutrient intakes (p<0.05). The higher the stress perception levels of the students, the higher the energy, coffee and alcohol intake, which predicts that appropriate stress control in college students will lead to better dietary habits. It is expected that the results above will be used as basic data for the development of proper nutrition education programs and stress control strategies.
