  • The purpose of this study was to develop a behavior rating scale for the evaluation of children's development for utilization by preschool teachers. The procedures for the study included content validation, pilot test, and main study. A total of 97 items were retained after the content validation and pilot test. The items of the scale were grouped into five areas (physical, language, cognitive, emotional, and social development) and 11 sub-areas. The resulting "Behavior Rating Scale for Preschool Children" was administered to 479 boys and girls, 3-6 through 6-5 years of age, selected from 10 different kindergartens and early education centers in Seoul, Pusan, and Chonju. The analysis of data was done with SPSS computer programs, including item analysis, Cronbach's ${\alpha}$ for reliability, factor analysis to test construct validity, two-way ANOVA to test age and sex differences, and percentile norms. The 97 items of the scale were found to be satisfactory in terms of item discrimination with indices ranging from .31 to .73. Cronbach's ${\alpha}$ was .98 for the total scale and ranged from .87 to .93 in specific domains, which was considered satisfactory. The factors extracted from each area were consistent with the educational objectives of the Yonsei Open Education Program except for emotional development. The intercorrelations among the domains were relatively high, ranging from .56 to .81. Age differences were significant in cognitive, physical, and language development, but not significant in social and emotional development. Sex differences were significant in all areas with girls higher on the average than the boys. Percentile ranks were drived from the total score for each age group and quartiles were calculated for sub-scores in each domain.

  • Various items were used as evaluation tools that identify the student's abilities accurately to confirm the completion of learning. Among them, the multiple choice item has the advantages of high objectivity and reliability in scoring, but it cannot remove the factor of guessing. In this paper, the multiple choice items are classified into two types according to the relationship between the questionnaire and the choices. One is the type used in the classical test theory with the probability of guessing 1/k for k choices and the other is the novel proposed type which introduces the concept of partial knowledge. In the proposed type, the probability of guessing when the number of knowledge i is (i+1)/k for k choices. Based on the assumptions of the previous theories about multiple choice items, we derive the guessing parameter about the proposed type. And we analyzed the effect of the guess on the correct answer in the existing type and the proposed type. This shows that the proposed type has more question guessing than the existing type.

  • The aim of this study was to develop a scale of the Korea citizen's intentionality out of their inborn ability and mission. To set up the concept of the above intentionality, there have been many academic and religious studies for reference in addition to the existing productivity, Korea elderly successful aging scale, and the scale of life qualities for review. The first 57 items for questionnaires were created thereafter. The final 27 items were confirmed, which were constantly modified by a professor of statistics and corresponding author in effective response and in removing the redundant items after the first items had been reduced to 44 preliminary items through the many an item-by-item discussions with pastors, theologians and social workers. A survey was conducted around the metropolitan area and 380 records were collected. Factor analysis to verify the validity of the measurement tool was completed, and showed that there were 6 sub-factors; "recognition of being", "autonomous life", "self-completion", "initiative", "acceptance", and "economic feasibility". In addition, reliability analysis was implemented and found to be reliable because the Cronbach's ${\alpha}$ value was 0.6 or more.

  • Objective: This study was conducted to investigate the relationship between the intention of smoking and its related factors in high school students. Methods: Our study subjects were 1,203 high school students who resided in one city and in one county region. We conducted a self-administered questionnaire survey from June 7 to June 19, 2004. Both the decisional balance and temptation inventory showed high reliability estimates. We provided good fit for the 12-item decisional balance inventory and the 10-item temptation inventory by using a confirmatory factor analysis. We also used multiple logistic regression analysis to identify the major contributing factors for the intention to start smoking. Results: On the univariate analysis, the subjects who were female, the 2nd and 3rd grade students, the students in vocational high school, the ex-drinkers or current drinkers, and ex-smokers were found to be significantly more distributed in the groups with intention to start smoking. Except for the concept of the cons, the group with intention to start smoking showed significantly higher standardized T scores for the 7 concepts of decisional balance and temptations. On the multiple logistic regression analysis, the females, the 2nd and 3rd grade students, the students in vocational high school, the experience of cigarette smoking and low T score of the cons were significantly related to the intention to start smoking. Conclusions: The intention to start smoking in high school students was affected by various factors such as gender, the school grade and the experience of smoking. Therefore, further research should be conducted for providing the essential data for developing a brief instrument for selecting the groups with intention of starting smoking among adolescents.

  • Purpose: This study was a prospective survey to evaluate the Korean Triage and Acuity Scale (KTAS) inter-rater reliability and to identify discordant areas in the KTAS classification between nurses and paramedics in emergency department (ED). Methods: Inter-rater reliability were evaluated using triage deta from January 11 to May 31, 2019. A convinience sample of a total of 800 patients who visited an emergnecy medical center in Incheon (400 adult and 400 pediatric patients in this study) were selected. The triages of this study a pair of one nurse and one paramedic performed triage at the same time, using the KTAS, Inter-rater reliability for the KTAS was evaluated with the weighted kappa. Results: The inter-rater reliability of the KTAS evaluated by weighted Kappa between nurse-paramedic KTAS score of adult patients was .71, and .66 for pediatric patients. Both were in the level considered as substantial. Among causes of triage discordance, the most frequently identified discordant item in triaging adults was the difference in the measurement of pain intensity (28.0%). For both adult and pediatric patients, multiple chief complaint was identified as the major discordant factor. In triaging pediatric patients the body temperature assessment by subjective judgments was the highest discordant item (50.7%). Conclusion: The study result suggested that the KTAS demonstrated a reasonable level of inter-rater reliability and functioned as a standardized triage tool for emergency medical services. In order to improve the inter-rater reliability and classification competence, it is necessary to revise the current all-integrated KTAS provider course to be differentiated for each job group.

  • The purpose of this study is to examine the validity and reliability of the Parental Satisfaction Scale for Child Care Centers, which modified the Client Satisfaction Scale (CSS; Kim, 2009). The subjects of the study were 652 parents of children who were between the ages of one to five and who attended child care centers. The five-point rating scale consisted of 21 items with two sub-dimensions. The results from an exploratory factor analysis identified that there are two dimensions in this scale. Thus, in terms of the face validity of this scale, a two-dimensional scale with 21 items is found to be appropriate. However, the items that consist of the two sub-dimensions are found to be different from that of CSS. The concurrent validity and internal consistency reliability of the revised scale are relatively high. Also, the mean between the upper and lower groups with regard to item discrimination show significant difference. We conclude that the original CSS with minor revisions can be used as a valid and reliable instrument to assess parental satisfaction on child care centers.

  • This study aims to develop an instrument for measuring high school students' action competence on climate change (ACoCC). The instrument is defined as the construct comprised of seven factors and thirty-five items and takes approximately 15 minutes to fill out. A panel of experts and students' content validation were undertaken to modify the items. Five hundred and twenty-eight first and second graders in Korean high schools participated in the instrument survey. To assess the reliability and validity of ACoCC instrument, item analysis (mean, skewness, kurtosis, item-total correlation), internal consistency estimate, and confirmatory factor analysis were used. It was appropriate to use the 7-dimensional ACoCC instrument (knowledge about climate change, climate change sensibility, reflection, communication, integrated thinking, willingness, decision making), with 35 items for high school students. The following instrument was self-report given in the 5-point Likert scale (1=strongly disagree, 2=disagree, 3=neutral, 4=agree, 5=strongly agree). The internal consistency coefficient was shown as a whole was shown as 0.953, and the subscale's internal consistency coefficient ranged from 0.786 to 0.862.

  • MMORPG genre is based on the belief that all users in virtual world are equal. All users are able to obtain the corresponding wealth or status as they strive under the same resource, time. However, game bot is the main factor for harming this fair competition, causing benign gamers to feel a relative deprivation and deviate from the game. Game bots mainly form GFG(Gold Farming Group), which collects the goods in the game indiscriminately and adversely affects the economic system of the game. A general game bot detection algorithm is useful for detecting each bot, but it only covers few portions of GFG, not the whole, so it needs a wider range of detecting method. In this paper, we propose a method of detecting GFG based on items used in MMORPG genre. Several items that are mainly traded in the game were selected and the flows of those items were represented by a network. We Identified the characteristics of exchanging items of GFG bots and can identify the GFG's item trade network with real datasets from one of the popular online games.

  • Purpose: The purpose of this study was to survey the operation and development direction in KPNFA. Method: The participants of this study consisted of physical therapists who had a KPNFA membership. The satisfaction levels for each item (KPNFA impression, educational programs, and clinical application) were measured using a 5-point Likert scale. The survey was performed during June and July 2018. The total questionnaire was comprised of 648 samples. For the data analysis, descriptive statistics and Spearman correlation analysis were used to compare the general characteristics and all items. Results: In the questionnaire, the impression of KPNFA was 69.21, the instructor specialization in the educational programs was 74.22, and helpful interventions for clinical application scored 74.96. KPNFA's image is competitive; friendly items scored the highest, and operation suitability and communication scored the lowest. The most important factor of the educational program was the quality of the instructors. The most helpful item was the education intervention program. The nervous system was applied to the patient with the highest response. The age of subjects showed a significant positive correlation with KPNFA impression, KPNFA branch impression, and branch problem solving. The work duration of subjects showed a significant negative correlation with instructor specialization. A regular member duration of subjects showed a negative correlation with teaching method, instructor specialization. Conclusions: The KPNFA survey was performed for the first time. In the future, this data will be utilized as the basis for KPNFA policy.
