This study investigates the perception of the general public through analysis of various potential risk factors reflecting nuclear power generation and nuclear power (radiation) and risks. A total of 293 copies of the data were collected from various strata in Busan. As a result, among the potential factors in everyday life, there was a high awareness of the risk to the fire. Next, the perception of risk for radiation terror and nuclear (nuclear) energy was relatively high compared to other risk factors. In the analysis according to age, educational background, and political ideological tendency, the results were contradictory to the necessity, risk and safety of nuclear power generation. The potential risk factors and the perception of nuclear power according to the tendency of political ideology were analyzed to be positive recognition of conservative ideology and negative recognition of progressive group. In other words, the perception of nuclear power was analyzed differently according to the tendency of political ideology. Therefore, it should be decided to reflect the opinions of experts and various opinions of the general public in the setting of nuclear radiation (radiation), it is believed that ordinary people need to take flexible action without having a vague sense of anxiety about various potential risks and nuclear power (radiation) based on objective and scientific grounds.

This study is based on parents that have preschool children of age 4~5, and analyzes the perception and parent education demand through parent experience of fire. As a result of the study about perception through parent experience about safety life, safety accidents, safety education of fire, the effect of parents' safety consciousness to fire safety life turned out to be moderate for fathers and large for mothers. The safety education method was mostly done in speaking than experience for fathers, while mothers did education through experience in daily life. Also the difficulties in safety education was lack of educating time for fathers while it was lack of knowledge and methods for mothers. Perception through parent experience of fire safety accidents showed that fathers did not have experience of fire safety accidents while mothers did. The locations perceived by parents where fires mostly occurred showed to be within home for both parents, and both administered first aid in managing fires. Perception through parent experience of fire safety education showed the importance of fire safety education to be important in both parents, and both parents had no experience in fire safety education. Also the fire safety education knowledge acquisition method was TV or the Internet for fathers, while it was participating in seminars or lectures for mothers. Fathers were moderately satisfied of the fire safety education instruction of childhood education centers, while mothers were slightly dissatisfied. For the demand of parent education about fire safety education, fathers were moderate while mothers thought it necessary of parent education necessity. The reason why parent education was needed was to be able to know immediate and prompt measures and first aid treatment in emergency situations for fathers, while it was to figure out the cause of fire safety accidents and prevent it beforehand for mothers. For the education institution of fire safety education, fathers demanded it for safety related institutions while mothers demanded it for children education institutions, and the number of times for parent education was once or twice a year for fathers while it was once a month for mothers. For the parent education instructor of fire safety education, fathers demanded safety education experts while mothers demanded infant teachers that completed the safety education course. For the fire safety education method of parent education, fathers demanded Internet searching while mothers demanded seminars or lectures.

This study presents the new method which can transfer the expert's skill to deburring robot through neural network. The expert's skill is expressed as associationmapping between the characteristics of the burr and human expert's action. Under the fundamental idea that the state of the deburring processcan be extracted via the visual sense of the human,we employ vision system for the perception and identification of the changing burr. Form the demonstration of human experts, force data are measured. Finally the characteristics of the burr and coressponding force are associated by the neural network which is trained through many demonstrations. The proposed method is verified in the deburring process of welding burr.

This study investigated how Korean food is perceived within a healthy diet and what kinds of eating habits Korean people have. A Focus Group Interview (FGI) was conducted with participants who were experts on diet. Data were categorized into five groups using content analysis. categories were as follows: 1) Korean food and health assessment, 2) opinion on Koreans' current eating habits, 3) characteristics of Korean food, 4) comparison of Korean food in the past and present, 5) a plan for healthy diet. Results showed that a healthy diet should not only include a lot of vegetables, simple and unprocessed food as well as less spicy food, but that it should also be well-balanced nutritionally.

The aim of the current study was to suggest priorities needed to be considered by university instructors when designing online learning. Based on three types of interactions (learner-content, learner-instructor, and learner-learner interactions) for effective online learning (Moore, 1989), draft questionnaires representing each type of interaction were written. After examining content validity by two Ph.D. experts, the survey was constructed with an Importance-Performance Analysis (IPA) form. Data of 133 university instructors were collected online. Results showed that support for designing learner-learner interaction was the priority for improving online learning. In terms of learner-instructor interaction, instructors needed to provide social-emotional support to learners so that learners could have a sense of belonging. For learner-instructor interaction, supporting instructors to monitor the level of understanding was the most highly demanding strategy for online learning. Limitations and suggestions for further studies were discussed.

Conflicts in public construction projects become more serious and complex so that they have a negative effect on performance of projecets. Conflicts in public construction projects are defined as expanding in complaints. This study analyzes the relationship structure and effect on performance between complaints and conflicts. First of all, 219 survey data collected from industry experts were used to derive complaints arising from the project and to understand the characteristics of each complaint. In the case of environmental damages, rather than environmental damage during construction, harmful substances or effects that can occur in completed facilities cause complaints from local residents, and opposition from environmental groups has a great effect on time and cost increase. As for safety damage, civil complaints related to prevention and countermeasures for safety accidents occur frequently, and additional construction affects cost increases. Through this study, it is possible to understand the serious complaints that are prone to conflict in public construction projects, their frequency, and the performance of the project.

The tonal music organizes the tones based on the hierarchy of the relative importance of musical tones. So listeners who are familiar with a certain musical style internalize the tonal schema of that music in mind, though they have no formal training about these organizing principles. This research examined how the western music experts who are not familiar with classical Korean music interpret classical Korean music. In the other researches about musical styles outside the western music, the superficial informations such as the distribution and the duration of tones in the experimental stimulus might be used as cues to extract the tonal schema of that music. In this study, these superficial informations were controlled in order to reduce this possibility. The results showed that the western music experts might interpret classical Korean music with the tonal schema of western music. but, thought the western music experts perceived classical Korean music on the base of the western musical framework and so their interpretation was not match with the tonal schema of classical Korean music. their interpretation was more similar to classical Korean tonal schema than the non-musicians interpretation of classical Korean music. These results suggested that the extensive experiences in a specific musical style can facilitate the listeners proper apprehension of the other musical styles.
