  • This study focused on estimating influential factors of traffic accidents and analyzing traffic accident severity of elderly and non elderly using traffic accident data. In order to reclassify elderly and non elderly traffic accident by a statistical method from entire traffic accident data, multiple discriminant analysis was applied. Also ordered logit model was applied for analyzing traffic accident severities using traffic accident severities as an independent variable and transportation facilities, road conditions and human characteristics as dependent variables. As results of the comparison between elderly and non elderly traffic accident, the traffic accident severity was affected by the age, types of traffic accidents, human characteristics and road conditions as well. Also, transportation facilities and road conditions affected to more elderly traffic accident than non elderly. Therefore, traffic accident severity would be decreased with the improvement of transportation facilities and road conditions for the elderly.

  • Recently, flowerbed median strips are being installed in urban highways for safety and scenery. In addition, efforts to enhance urban image through roadside flowerbeds and trees are being exerted for afforestation to enhance the urban environment. The sensibility of humans, such as the feeling of agreeableness of drivers must be considered when planning roads. However, not many researches on users on road environment are being conducted. Accordingly, KANSEI Engineering that is attracting attention nowadays was applied to form the image or sensibility of humans as definite object, in order to grasp the relation between the personal attributes of users and road formation with sensible factors considered when the road users evaluates the road scenery. As the result of research, streetscape was not evaluated based on individual factors such as roads, trees and buildings that form roads, but was based on sensibility image based on harmony of the overall road formation according to the changes of each factors.

  • This study was carried out to establish an effective marketing strategy based on Importance-Performance Analysis (IPA) of rice-convenience foods. IPA is one of the most efficient and simple methods to evaluate product quality. Data were collected from 652 people (320 males and 332 females) and analyzed by SPSS 19.0. Subjects consumed rice-convenience foods as a snack substitute (19.3%), breakfast (20.7%), lunch (37.4%), dinner (15.2%), and late-night meal (7.4%). The purpose for consumption of rice-convenience foods were as follows: light meal (34.8%), lack of time to prepare meal (42.2%), favorite restaurant is not nearby (2.3%), save money (3.4%), and outdoor activities (9.7%). All attributes about rice-convenience foods were categorized into intrinsic property and extrinsic property. As a result of factor analysis, health, sensibility, and diversity factors were extracted from intrinsic property. In addition, dependence and appearance factors were drawn from extrinsic property. In analyzing the differences between importance and performance, there were significant differences; 16 items in the intrinsic property (P<0.01), and 10 items in the extrinsic property (P<0.001). The IPA matrix is composed of four quadrants, and each represents different strategies; the first, 'keep up the good work', the second, 'possible overkill', the third, 'low priority for management', and the fourth, 'concentrate management'. As a result, factors of rice-convenience foods positioned in the fourth quadrant were 'safety (from food additives, etc.)' and 'price' in the intrinsic property and 'nutrition label' and 'safety of packaging material' in the extrinsic property. They need to be improved immediately. In this study, rice-convenience food factors for continuous maintenance and concentrative improvement were compared by IPA. Based upon the results of this study, it is necessary to develop methods to make efficient use of limited resources and practical marketing strategies.

  • When viewing that since the 1990s local governments have tried to build golf courses as a plan to revitalize the attraction of home and abroad tourists and to increase their tax incomes and that big companies are interested in leisure business including golf courses as a future promising business in the 21st century, golf courses seem to continuously increase in the future. On the contrary, noticing that golf courses are not only the main culprit behind the damage of natural environment and environmental pollution but also a target of real estate speculation and that golf makes a sense of incongruity between the classes of a society as a luxury sports, environment activists and local residents raise criticism to golf. Golf in our country shows a special sports phenomenon of which the pros and cons appear continuously. So, it is judged that policy for golf development direction should be set up based on verified scientific data. Thus, the research aims at deriving the location types of golf courses by looking at laws from the period of formation of the initial domestic golf courses to the recent period, grasping their distribution status according to time series and regions, conducting a questionnaire survey regarding location factors for golfers and the workers of golf courses, and dividing golf courses into several types. It is expected that the research will be a fundamental material when a golf course is built later on, contributing to the research of golf courses.

  • This study was conducted to identify the factors influencing patient safety behavior and performance of infection control in nursing students. This study was a descriptive survey based on data collected from August 28, 2017, to September 22, 2017 from 174 third and fourth year nursing students at E university located in S city of Gyeonggi. The collected data were analyzed using the PASW 23.0 program to conduct an independent t-test, one-way ANOVA, post-hoc Scheffe's test, Pearson's correlation, and multiple regression. The average scores of patient safety behavior and performance of infection control were $4.00{\pm}0.55$ and $4.31{\pm}0.50$, respectively. Patient safety behavior and performance of infection control showed a strong positive correlation. Patient safety behavior was positively influenced by confidence levels of patient safety and awareness of the infection control, and the explanatory power of the model (R2)[ED highlight - should this be R2? If so, change throughout the paper.] was 55.1%. Predictors of the performance of infection control were patient safety knowledge, confidence levels regarding patient safety, and awareness of infection control, and the R2 was 68.1%. Common factors influencing patient safety behavior and infection control performance were patient safety confidence and development of effective clinical practicum education programs to increase confidence in patient safety and infection control.

  • The purposes of this study were to survey internal engagement in science fair and explore the causal relationship between internal engagement and motivation for participation. A written questionnaire on queries into motivation for participation and internal engagement were developed and tested. The subjects were 1066 students from 4th to 9th grade who had participated in the Youth Science Contest under the auspices of the Korea Science Foundation. Interest and commitment were selected as constructing factors of internal engagement. Through exploratory factor analysis, preference, reward, and social motivation were determined to be the factors affecting the motivation to participate. Boys showed higher internal engagement than girls, and interest and commitment were found to be higher in elementary school students(p<0.01). There was no difference in interest among elementary school students; however, fourth grade students showed lower commitment than other students(p<0.01). Ninth grade students showed the lowest interest and commitment among junior high school students(p<0.01). To explore the causal relationship between internal engagement and factors influence internal engagement, path analysis was used. The selected model illustrated how reward motivation affected commitment directly, and how preference motivation affected interest directly but only commitment indirectly through interest. Reward motivation affected commitment with a standardized direct effect coefficient of 0.17. Preference motivation affected interest with a standardized direct effect coefficient of 0.75 and commitment with a standardized total effect coefficient of 0.63(direct effect; 0.27 and indirect effect; 0.36). In addition, interest affected commitment with a standardized direct effect coefficient of 0.49. Social motivation did not affect interest and commitment and reward motivation did not affect interest.

  • We sought to develop a multi-dimensional tool for measuring and understanding nurse fatigue. The participants were 301 nurses working in four hospitals in Seoul, South Korea. Basic items were developed after a preliminary literature review, and content validity was verified by a group of experts. The first 52 items from which the fatigue measurement tool was to be developed were tested for construct validity and were reduced via factor analysis to 31 items. Following a confirmatory factor analysis, the items were further reduced to 23 items in three categories: physical, mental, and emotional. A confirmatory factor analysis found the items to be adequate. The fatigue scale was found to have high construct validity and reliability. This scale is expected to serve as a preliminary data-gathering tool to assess the level of nurse fatigue and to develop interventions to alleviate it.
