Purpose: This study was done to develop and evaluate a drug dosage calculation training program using cognitive loading theory based on a smartphone application. Calculation ability, dosage calculation related self-efficacy and anxiety were measured. Methods: A nonequivalent control group design was used. Smartphone application and a handout for self-study were developed and administered to the experimental group and only a handout was provided for control group. Intervention period was 4 weeks. Data were analyzed using descriptive analysis, χ 2 -test, t-test, and ANCOVA with the SPSS 18.0. Results: The experimental group showed more 'self-efficacy for drug dosage calculation' than the control group (t= 3.82, p< .001). Experimental group students had higher ability to perform drug dosage calculations than control group students (t= 3.98, p< .001), with regard to 'metric conversion' (t= 2.25, p = .027), 'table dosage calculation' (t= 2.20, p = .031) and 'drop rate calculation' (t= 4.60, p< .001). There was no difference in improvement in 'anxiety for drug dosage calculation'. Mean satisfaction score for the program was 86.1. Conclusion: These results indicate that this drug dosage calculation training program using smartphone application is effective in improving dosage calculation related self-efficacy and calculation ability. Further study should be done to develop additional interventions for reducing anxiety.

The purpose of this study was to develop Korean Infant Vocal and Articulatory Development (KIVAD) list and to set up a baseline for ultimately applying for articulations and vocalization of infants' aural rehabilitation program.

The objective of this study is to develop an Infant-Toddler Auditory & Communicative Behavioral Checklist (IT-ACBC). Methods: After analyzing several domestic related studies and 11 foreign checklists, 33 keywords were investigated. From the key words, the 72 preliminary items, 6 items for 12 month groups, were developed. 12 month groups were composed of 1

The objective of this study was to analyze the reliability and validity, and compare the Infant-Toddler Auditory and Communicative Behavioral Checklist (IT-ACBC) to general developmental levels of Korean Developmental Screening Test for infant & children (K-DST) for identifying characteristics of the checklist. Methods: IT-ACBC were administered by 287 parents of the normally developing infants aged from 1-26 months. After considering internal consistency reliability, frequency of response to each month group, and questions from respondents, 36 items, 3 items for 12 month groups, were finally extracted from the preliminary items. The internal consistency of items and test-retest reliability were calculated. The validity for items were conducted by attempting a concurrent validity analysis. Average and standard deviation of IT-ACBC was analyzed to standardize a criterion. The correlation between auditory and communicative behavioral ability of IT-ACBC and 6 general developmental skills of K-DST scores were obtained to identify their relationship. Results: The Cronbach's alpha coefficient of IT-ACBC was 0.964. The test-retest reliability was quite high with r = 0.962. The score of the checklist was significantly correlated with 'LittlEARS Auditory Questionnaire-Korean' score. The score of the IT-ACBC was significantly correlated with the language score of K-DST (r = 0.426). Conclusion: IT-ACBC was developed and standardized scores were provided to evaluate auditory and communicative behavior in typically developing infants and toddlers. IT-ACBC can be utilized for checking auditory and communicative behaviors briefly. Further, IT-ACBC also can be utilized to assess auditory and communicative behaviors for multi-handicapped children comparing with other functions of K-DST.
