Purpose: This study aimed to develop and test a reward scale for hospital nurses. Methods: The initial items were identified through a literature review and focus group interviews with ten hospital nurses. The content validity of the items was evaluated by ten experts. Fifty-one items were derived from the pilot survey. Four hundred eighty-eight nurses participated in the study: 248 for exploratory factor analysis (EFA) and 240 confirmatory factor analysis (CFA). Data were analyzed using item analysis, EFA, CFA, convergent validity, known-group validity, and internal consistency using IBM SPSS Statistics 29.0 and IBM SPSS AMOS 29.0. Results: The final scale consisted of 31 items and eight factors (decent wage, opportunity to grow and develop, support for special situations, various benefits, flexibility of work, job-related achievement, reflecting career and performance, and recognition), which explained 67.3% of the total variance. The eight-subscale model was validated by CFA. Convergent validity was evaluated by analyzing correlation with intention to leave (r = - .63, p < .001) and job satisfaction (r = .54, p < .001). The known-group validity was evaluated by comparing the reward scales according to age, clinical career, income level and hospital type. The scale was found to be reliable with a Cronbach's α of .89. Conclusion: Both the validity and reliability of the reward scale for hospital nurses are verified, which can enhance the understanding of the range of rewards and may assist nurse managers in establishing an effective reward system.

As a part of advanced technology society, South Korean youth have been accessing the Internet at a very high pace. The Internet overuse could yield addiction where may be a serious psychological disorder of this century. The literature remarks that gender could make a significant difference on internet addiction. Therefore, this study aims to examine the effect of gender variable on internet addiction for a sample of South Korean university students (n = 815; 312 females and 503 males). The instrument had two sections; the demographics and twenty Internet Addiction survey items based on a five level scale; "Rarely, Occasionally, Frequently, Often and Always". The results showed that general tendency among the participants appeared between "Occasionally" and "Frequently" for internet addiction. In order to test five derived study hypotheses, the researchers conducted comparative statistical tests. The t-tests revealed that gender made statistically significant differences on nineteen items where males were higher than females showing that males significantly spend more time on the Internet than females. Additionally, t-tests results showed that seventeen of the survey items showed statistically significant differences with respect to types of technology dominant environment. The researchers created two dummy variables to combine gender and technology dominant environment variables and gender and school year variables, to have a better understanding the gender effect with one-way ANOVA. The gender difference still exists following its merge to technology dominant environment showing that the gender surpasses IT related environment. When school year combines to gender, males show higher scores for certain items, especially for freshman year.

This comparative study was conducted to compare the attitudes of sexuality and knowledge of sexual violence between male and female college students. The subjects of this study were 222 male students and 200 female students. The survey was conducted using a questionnaire of 3 general characteristics, 11 items to test attitudes on sexuality, 10 items to test knowledge of sexual violence, 1 item on the cause of sexual violence and 1 item to check knowledge of sexual violence countermeasures. According to the SPSS/PC Program, Frequency, mean, percentage, t - test, Pearson correlation coefficient were used in analyzing the data. The results of the study are summarized as follows. 1. The result of the comparison between two groups was significantly different in their attitude on sexuality(t= -4.16, P<.000). Female students had higher scores than male students. 2. The result of the comparison between two groups was significantly different for their knowledge on sexual violence(t= -6.82, P<.000). Female students had higher scores than male students. 3. As a countermeasure for prevention, sex educations is needed(27%). 4. Very high correlations were observed between a subject's sex and his /her sexuality(r=.1990, P<.0001), between a subject's sex and his /her knowledge of sexual violence(r=.3157, P<.0001), between a subject's attitude on sexuality and his /her knowledge of sexual violence(r=.2538, P<.0001).

Characteristics of Superior Children as a Screening Test of Gifted students The purpose of this study was to investigate the usefulness of Korean version of checklist for behavioral characteristics of superior children as a screening test for gifted students. Total 397 children were tested KEDI-WISC (Korean version of Wechsler Intelligence Scale for Children), and their parents or primary caretakers took the checklists for behavioral characteristics of superior children individually. Total subjects were divided into 3 groups based on their Full IQ score of KEDI-WICS. The children of IQ 130 and over was gifted group, and those of IQ 115-130 was superior group, and those of below IQ 115 was average group. The analyses of behavioral checklist scores among the groups, gender, grades differences and item analysis of behavioral checklist were done for the purpose of discrimination among 3 groups. As a result, it was found that the Korean version of checklist for behavioral characteristics of superior children was very useful as a screening test for gifted correlations between checklist scores and verbal, performance and full IQ scores were significantly high, which means that IQ and checklist scores were very related. Twenty out of 50 items were found to be discrimination items between gifted and superior group. However, there was no significant difference between grades and gender on the checklist score.

This paper presents a novel method to construct a personalized e-Learning system based on dynamic estimations of item parameters and learners' abilities, where the learning content objects are of the same intrinsic quality or homogeneously distributed and the estimations are carried out using IRT(Item Response Theory). The system dynamically connects the test and the corresponding learning procedures. Test results are directly applied to estimate examinee's ability and are used to modify the item parameters and the difficulties of learning content objects during the learning procedure is being operated. We define the learning unit 'Node' as an amount of learning objects operated so that new parameters can be re-estimated. There are various content objects in a Node and the parameters estimated at the end of current Node are directly applied to the next Node. We offer the most appropriate learning Node for a person's ability throughout the estimation processes of IRT. As a result, this scheme improves learning efficiency in web-base e-Learning environments offering the most appropriate learning objects and items to the individual students according to their estimated abilities. This scheme can be applied to any e-Learning subject having homogeneous learning objects and unidimensional test items. In order to construct the system, we present an operation scenario using the proposed system architecture with the essential databases and agents.
