The purpose of this study was to compare the visitor's satisfaction factors and causal relationships among the 2010, 2012, and 2016 Korea International Exhibition of Machinery Equipment, Science and Technology for Agriculture. A total of 17 variables to evaluate the level of satisfaction were divided into three factors: contents, publicity and guidance, and environment of convenience facilities. The results were as follows. First, from 2010 to 2016, the Expo showed quantitative and qualitative growth in terms of the number of visitors, firms, and performances. Second, in 2016, the number of visitors aged below 20, foreigners, and new visitors increased year-on-year. Third, the contents, publicity and guidance, and satisfaction were higher than in the last two cases, but the environment of convenience facilities showed no difference among the years. In addition, the revisiting intention in 2012 was higher than that of 2016. Lastly, all three factors had a significant impact on the level of satisfaction in 2016, but publicity and guidance and environment of convenience facilities in 2010 and 2012 were not significant factors on satisfaction. Furthermore, the satisfaction of all three expos was confirmed to be a significant factor for the visitor's revisiting intention.

Child sexual crimes have increased, but there has been no effective plan to combat this. Films reporting problems, amplify the attentions and propose countermeasures, which leads to changes. The current study examined the audiences' reactions to child sexual crime faction films using text-mining. The analysis of Naver's 2,727 blogs showed realistic words while 3,000 review comments' analysis demonstrated emotional responses. The positive and negative emotional category and degree were also different. In , the higher degree of negative emotions, such as 'angry' and 'unpleasant' appeared frequently. In , only negative emotional worlds were used. On the other hand, 'sad' was the highest ranked word, and the negative level was weak. In , 'good' a positive emotional word solely emerged. The audiences perceived the accidents objectively before release while they expressed their emotions and feelings after watching the movies. caused explosive anger and organized the participating citizens for changes. This movie provided an opportunity to enforce a legislative bill intensifying heavy punishments. The present study is significant in scrutinizing the audiences' diverse emotional reactions and discusses the future direction of society prosecution movies. Based on the text analysis of the audiences' linguistic expressions, a future study will be needed to hierarchically classify the diverse emotional expressions.

This study was conducted to investigate the level of physical activity and identify factors influencing physical activity of first and second year nursing students. The participants were 234 female first and second year nursing students at one nursing college located in U city. Data were collected from September 5 to 15 in 2016 and analyzed by descriptive statistics, t-test, ANOVA, $Scheff{\breve{e}}$ test, Pearson's correlation coefficient, and stepwise multiple regression using SPSS/WIN 22.0. The average level of physical activity measured by the Korean version of the Godin-Shephard Liesure-Time Exercise Questionnaire was 9.09(range 0-80). According to the physical activity group classified by leisure score index, there were 25 students(10.7%) in the active group, 31 students (13.2%) in the moderately active group, and 178 students(76.1%) in the insufficiently active group. Factors influencing the level of physical activity were intention to participate in physical activity and habit to physical activity, which together explained 21.2% of the total variance in physical activity. Therefore, this study suggests that it is necessary to develop and apply a physical activity program enhancing intention and habit to physical activity for first and second year nursing students.

Among the various sensors for measuring traffic, PVDF (polyvinylidene fluoride) piezoelectric sensors are used to classify vehicles because they can detect the axle of the vehicle. Piezoelectric sensors are embedded in road pavements and are always exposed to traffic loads and environmental loads. Therefore, the life expectancy is very short, less than 6 years. Traffic control is essential for reinstallation and data collection is interrupted during the failure period. The lifespan will increase if the sensor installation depth is increased. In this study, the sensor signal output was analyzed with a variable depth of sensor installation to verify the possibility of deeper installation. Furthermore, various parameters, such as the weight and speed, were analyzed. The wheel load is applied using APT. As a result, the MSI BL sensor output signal is higher than 100mV when installed at 3cm, which is reliable. If the location of the sensor is deeper in the pavement, the expected lifetime of the sensor is also increased. On the other hand, the MSI cable was found to be less than 100mV at the shallowest depth of 1cm, making it impossible for field applications.

This was a retrospective study that compared the characteristics of patients with decreased mental status (DMS) during their stays in an emergency department (ED) with that of patients with alert mental status (AMS). The participants in this study consisted of 90 patients with DMS who were staying in an ED along with 100 randomly selected patients with AMS. The DMS group contained more instances of cerebrovascular disease, liver disease, diabetes, and hypertension compared to the AMS group (p=0.001, p=0.003, p<0.001, and p=0.002, respectively). With regard to triage, the DMS group had higher severity than the AMS group (p<.001). The final diagnosis for the DMS group was as follows: 64.9% neurological and 63.3% related to the digestive system, which differed from that of the AMS group (p<.001). Fifty-six (62.2%) patients with DMS had their statuses discovered by nurses, while nine patients in the DMS group had received cardiopulmonary resuscitation. These results suggest that ED nurses frequently assess the consciousness of patients who they suspect may have neurologic or digestive diseases and are classified as high severity, even when the patients are alert.

To cope with the increasing number of natural disasters in recent years, managers in the National Disaster and Safety Status Control Center, who have considerable experience and skills, are regarded highly important. Although the National Disaster and Safety Status Control Center oversees the disaster-status control tasks in preparation for various natural and social disasters, there is little data due to the frequent replacement of managers. Therefore, this study developed a disaster-safety code system that tracks and manages disaster information, because the current record management and amount of information sharing remains very low. Among 22 natural and social disaster types, this study targeted four types of disasters: heavy snow, strong winds, high seas, and heavy rain. The final disaster-safety data code system was proposed through the following processes: analysis of the code systems of disaster areas in Korea and overseas, setup of the implementation of directions, development of the classification system, and categorization. For the systematic accumulation of data, the four code systems were integrated into one. A prototype system was developed and operated to verify the validity of the proposed code system. The results showed that data were accumulated and services were provided accordingly with respect to the proposed code system. If past data are accumulated and utilized according to the proposed code system in this study, it will be helpful in the decision making process to respond to new types of disasters, based on past experiences.

This study analyzed whether differences in individual characteristics and parental attachment affect the career maturity of middle school students in grades 1-3 in Asan, South Korea. Individual characteristics included gender, grade, grades, parental education, and economic level, while parental attachment included mutual trust, alienation, and communication. Career maturity included determinism, objectivity, readiness, independence, and assurance. Results showed there were significant differences in gender, grades, and economic level. Only gender differences affected attachment to mothers, with female students exhibiting stronger effects than male students. Grades that both the father and the mother showed differences. The economic level differed only in father's attachment. The effects of parental attachment on career maturity were found to be higher in career maturity with lower father's alienation and higher mother's mutual trust. Career maturity did not affect the assurance variable. Mother's communication affected determinism and mutual trust affected objectivity. Father's mutual trust and mother's communication affected readiness, and father's alienation showed a negative relationship. Mother's mutual trust positively affected independence. These results may be a valuable reference for understanding the behavioral psychology of adolescents and their parents. However, there is a limit to the generalizability of this study.

The purpose of this study is to find out the tendency and meaning of metaphors for block play. For this purpose, responses from 165 teachers in J area day care centers were collected using sentence completion metaphors. Collected data were analyzed through a categorization process using a qualitative research method based on previous research into metaphor analysis. From the results, first, block play trends from the metaphors were classified into two categories: content of block play, and characteristics of block play. The frequency in the order for Building Value of Play was higher. For the content of block play, composition had the highest frequency for trait of block play, and the basis of growth and development had the highest frequency in the Value of Block Play category. Second, the meanings of block play metaphors are composing, expressing, imagining, pleasure, freedom, and value of block play under Category Play, which was recognized as the basis of development, emotional development, social development, and creativity. Based on the results of the study, the value and role of block play in early childhood teacher education and in-service education should be further emphasized.

This study examines the clinical availability of alpha amplitude, asymmetry and mean frequency in old age as EEG indexes reflecting brain health condition. The EEGs of prefrontal lobes in eye closure state were measured for 4 minutes with 72 male and female elderly people aged 73. Subjects were divided into higher and lower groups based on average values of alpha amplitude, asymmetry and mean frequency. The results of correlations and t-test among EEG indexes were as follows. First, the higher Alpha altitude was, the higher physical and mental stress resistance and left-to-right brain communication were, and the lower mean Alpha mean frequency location was. The higher Alpha asymmetry was, the lower left-to-right communication level was. Second, as Alpha power of right brain was higher than that of left brain, Alpha amplitude and mental stress resistance and left-to-right brain communication level were higher. Third, as Alpha mean frequency location was higher, Alpha amplitude and mental anti-stress level were lowered and arousal level was enhanced. These high correlations and complementary meaning among quantitative EEG indicators demonstrated the possibility of biomarkers reflecting brain health state in old age.

The acreage of tangerines in the U.S. sharply rose from 19,000 ha in 2009 to 27,000 ha in 2016, an increase of 42% in 7 years. Considering the recent surge in tangerine exports to Japan, the export volume of 6-7 thousand tons is highly likely to increase in the future. Therefore, the purpose of this study was to analyze the economic impact of U.S. tangerine imports on the Korean citrus industry under various scenarios. In order to examine the possibility of imports of U.S. tangerines, the unit price of U.S. exports to Japan was used since U.S. tangerines are not imported to South Korea. Citrus fruits are divided into field citrus, house citrus, and late-maturing citrus (including winter season citrus) based on the cultivation method and variety used to analyze. Considering both the field and house seasons, the import volume of U.S. tangerines can be expected to rise from roughly 4,700 tons in 2021 to 10,000 tons in 2027. Imports of U.S. tangerines may be pushed up or delayed depending not only on the harvest method and quality of domestic field and house citrus but also on the harvest of U.S. tangerines. However, it is necessary to note that tangerines could be imported after 2021, when the tariff rate on U.S. tangerines will fall below 50%.
