Creativity is a fine ability among major values of human resource in knowledge-based society. The purpose of this study is to identify the components of the informatics creativity based on domain-specificity and confluence theory. To explore these components, a three-round, classical Delphi process was administered with an expert panel of 31 individuals. All members of the expert panel initially responded to open-ended questions, and the qualitative results were analyzed. The subsequent two rounds of the Delphi required quantitative responses in which the expert panel was asked to indicate the level of importance using a five point Likert scale associated with specific items. As a result of the Delphi survey, total of 32 items were selected as three core areas such as congnitive, affective and environmental components of informatics creativity.

In this study, human mimic phantoms outputted by three-dimensional (3D) printing technology are reported. Polylactic acid and a personal 3D printer - fused deposition modeling (FDM) - are used as the main material and the printing device. The output of human mimic phantoms performed in the following order: modeling, slicing and G-code conversion, output variable setting, 3D output, and post-processing. The students' learning satisfaction (anatomical awareness, study interest) was measured on 5-point Likert scale. After that, Twenty of those phantoms were outputted. The total output took 11,691 minutes (194 hours 85 minutes) and the average output took 584.55 minutes (9 hours 7 minutes). The filament used for the experiment was 2,390.2 g, and the average use of the filament was 119.51 g. The learning satisfaction of anatomical awareness was 4.6 points on the average and the interest of the class was on average 4.5 points.

The aim of this study was conducted to investigate the level of awareness and performance of the physical therapists on nosocomial infection and evaluate potential factors as associated with awareness and performance in order to provide fundamental data for the development of program and policy on the prevention of it. The data were collected from 405 physical therapists. The research instrument was self-administered standardized questionnaire including general characteristics, education status, necessity of the education on nosocomial infection, and awareness and performance for prevention of nosocomial infection. Responses were determined as 5-Likert scales and data were summarized as percentage, mean and standard deviation. Data were analysed using independent t-test, ANOVA and Pearson's correlation coefficient(${\alpha}=0.05$). The results of this study show that most physical therapists have not received education on nosocomial infection. For this reason, they have a low level of the awareness and performance on nosocomial infection, but they strongly recognize the necessity of the program and education for the prevention of nosocomial infection. Thus, these program and education are needed in each college as an academic curriculum, as well as in hospitals.

The purpose of this study was to examine if Likert scales had been properly utilized in community nutrition research. A total of 527 research articles published in the 32 issues of Korean Journal of Community Nutrition from the volume 5, issue 1 in 2000 to the volume 10, issue 2 in 2005 were screened and 55 articles were found to have utilized one or more Likert scales for the studies. Therefore, 109 Likert scales used in the 55 studies were reviewed regarding the name, statement and response items, reliability and validity check, and analysis method. The scales were mostly referred as Likert scales (60%) or Likert-type scales (27%). Some scales were found to be referred as Likert scales although they were Likert-type scales when judged based on the information given in the respective articles. However some scales couldn't be judged for the rightness of the names because the information given for the scales in the articles was not enough. About 23% of the scales consisted of items less than 6 or more than 30, and therefore found to be inappropriate. The percentage of the scales listing all the statement items in the articles was only 25%. Most of the scales (85%) included 5 response items, and the rest included 4 (7%), 7 (6%), or 3 (2%). The percentages of the scales including appropriate center and end items were only 2% and 22%, respectively. Less than half of the scales (41%) were found to have been checked for reliability and only one scale was reported to have been checked for validity. In some scales (6%), the responses were scored improperly for analysis. The responses to the scales were frequently found to have been analyzed by parametric statistics such as mean, ANOVA, t-test, and Pearson's correlation, which might be a problem depending on the size and distribution of study samples. In conclusion, there is much room for improvement in the use of Likert scales in community nutrition research.

This study is designed to evaluate the service quality of public libraries according to managing entities by LibQUAL+ and to devise ways to improve problems based on comparison and analysis of the differences in the service qualities. To achieve this, four public libraries in Seoul according to the managing entities were investigated. They consisted of libraries of public corporations, cultural centers, foundations and universities. Minimum service quality level, desired service quality level and perceived service quality was analyzed based on nine-point Lickertis scale. A survey was employed and consisted of twenty-two items. The results showed that current level of service met the minimum level, yet failed to reach their desired service level. The study suggested that public libraries contracting out to private sector need to actively apply users' demands and the changing environment of libraries, and continue to strive to provide public library users with high quality service through efforts of evaluating and improving the services for their users.

This study endeavors to propose factors that should be intensively managed by using an IPA model to analyze the strengths of military logistics. Based on the improvement measures, we constructed a questionnaire with 5 points of Likert scale and analyzed the importance and satisfaction through SPSS 23. Examination of several evaluation factors revealed 'expansion of and modernization storage facilities' as the most important factor, 'merger and abolition of regional logistics work' (3.56) had the highest satisfaction level. Factors involving the expansion and modernization of the storage facilities showed the largest difference between importance level and satisfaction level, at 2.01. This indicates the necessity for an overall review of the expansion and modernization of storage facilities related to military logistics. This study aims to identify the areas that should be improved firstly in military logistics and concentrate on management to create more effective results. Thus it suggests that this study has a concentration on management for the streamlining of military logistics.

This study was conducted on the visitors regarding their usage and evaluation state of the interpretive media which is utilized as a self-guide environment interpretation for the purpose of accumulating basic data for the park management. A questionnaire survey was chosen and the 275 valid samples among them were analyzed. The socioeconomic and behavioral characteristics of the visitors turned out to be similar with the results from another visitor survey in the same site. Among those who used the interpretive media, the largest proportion(77%) used the information board resources of the park; the usage rate of interpretive labels of woody plants, interpretive signs of cultural assets, and LED signs were shown to be relatively high. The usage of park brochures, park web sites, visitor center exhibits, and bulletin boards were less than 40% each. Visitors were asked to evaluate the importance and performance of the nine interpretive medias using a Likert Scale whose value ranges from one to five. The result recorded averaged above 4, which proved that the respondents were perceiving the importance of all forms of interpretive media greatly. The performance of interpretive media was also evaluated as affirmative, except the visitor center exhibits.
