Purpose: This study was done to develop and evaluate a smartphone application for the medication confirmation of high-alert medications. Methods: A nonequivalent control group non-synchronized design was used for this study. Participants in the treatment group used the application for four weeks. Data were analyzed using descriptive analysis, ${\chi}^2$-test, and t-test for the homogeneity of participants, and a paired t-test for effectiveness in each group with the SPSS 18.0. Results: Stability of medication administration was estimated by knowledge and certainty, ranged from a score of one to three. A correct answer with high certainty was coded as high stability, low certainty regardless of correct answer was coded as a moderate stability, and incorrect answers with high certainty were rated as low stability. There were no differences in 'knowledge of high alert medication', 'Certainty of knowledge', 'stability of medication administration', 'confidence of single checking medication', and 'medication safety activities' between the treatment group and the comparison group. The treatment group reported a greater difference between pretest and post-test in 'certainty of medication knowledge' (t=3.51, p=.001) than the comparison group. Conclusion: Smartphone application for medication confirmation of high-alert medications will provide an important platform for reducing medication errors risk.

This study aimed to develop smartphone application contents for the medication reconciliation of high-alert medications and to evaluate the satisfaction for this application. The xcode 4.5 and ios 6.1 SDK(software development kit) were used for constructing screen of the system. After implementation during 4 weeks, thirty five ICU(Intensive Care Unit) nurses were asked function related, contents related, and usage related satisfaction using 12 items. And differences of satisfaction according to the number of daily use and the frequency of use were evaluated. Data were analyzed using descriptive analysis, ANOVA with the SPSS 18.0. We developed the formula for drug dosage calculation, the alarming procedure, and the information of the high alert medication. In the satisfaction items, the mean score of 'This application is helpful to perform drug dosage calculation' was 3.14. However, 'I satisfy this application' was relatively low as 2.94. There were no differences in satisfaction according to the daily use and frequency of use. Based on the results of this study, more advanced smartphone application for medication reconciliation of high-alert medications will provide an important platform for patient safety.

Objectives : Although antipsychotics are commonly used to control symptoms of delirium, there is a lack of research on the prescription pattern and its clinical effects. The purpose of this study was to investigate the effect of antipsychotics prescription pattern on clinical course of delirious patients consulted to psychiatry. Methods : During the period from July 2016 to February 2017, 212 patients who were referred for delirium were reviewed for their medical records. The duration of delirium was monitored using CAM-ICU, and duration of admission, mortality, and delirium at discharge were reviewed. Clinical course was compared among three groups according to the antipsychotic drug administration pattern: Continuous use group, optimal use group and PRN use group. Results : The pattern of taking antipsychotic medication longer than duration of delirium did not associated with better clinical course compared with the pattern of adapting to the period of delirium and rather increased the risk of taking antipsychotic medication at discharge. When used for a shorter period than the delirium period, it was associated with poor clinical course. Conclusions : The results of this study suggest that a strategy to administer antipsychotics for a minimum period, according to periods of delirium, is appropriate. Also, efforts are needed to minimize the use of antipsychotic drugs after recovery from delirium.

PraziquantEI ($Distocide^{\circledR}$), the KcrEan product, was tEstEd for its safety and Efficacy in treatmEnt of Clonorchis sinensiJ infccticn during the period from April to SeptembEr, 1983 in Korea. A total of 55 egg positive cases were selected and treated with the regimen of 25 mg/kg t.i.d. for 1 day (total 75 mg/kg). The follow-up stool examination was done in 47 cases by cellophane thir;k smear and Stoll's egg counting techniques. The 8 uncured cases were treated again with the same regimen. The laboratory tests for blood picture and liver function were done in 27 cases and compared before and after the treatment. The results obtainEd are as follows: 1. After single course treatment, the cure and egg reduction rates were 83.0 and 99.1% respectively. With the second treatment, excellent results of 100% in both rates were obtained. 2. Several kinds of side effects such as dizziness, headache, etc. were complained by 29 cases (61.7 %), however, those were so mild and transient that no special treatment was necessary. 3. No significant change in laboratory findings was recognizable before and after the treatment. From the above results, it is concluded that $Distocide^{\circledR}$ is as effective and safe as $Biltricide^{\circledR}$ and highly recommendable in treatment of C. sinensis infection.

Objective: These studies were undertaken to evaluate the effects of the different administration duration of Morindae Radix extract solution on spermatogenic abilities such as concentration, motility and morphological normality of sperm from the testes and the activities of sperm hyaluronidase. Materials and Method: We used 8-week-old ICR mice and administered 0.3mg/g extract solution of Morindae Radix once a day for 30, 60, 90 and 120 days. The control group was administered normal saline in the same way and duration. We examined the number of total, motile and normal sperm from the cauda epididymis. We also compared the testicular tissue, especially seminiferous tubules, between the control and treated groups by histochemical methods. Finally, we observed the difference of sperm hyaluronidase activities between the control and treated groups. Results: Significant administration duration-dependent differences were observed in the concentration of total sperm, motility and normality of spermatozoa of the Morindae Radix extract solution administered groups compared to the control group. In the histological analysis of the testicular tissues, the enlargement of testicular lobe diameter and apparent vasculogenesis between testicular lobes were observed in the Morindae Radix extract solution administered groups compared to the control group. Also, the activity of hyaluronidase was significantly increased in the Morindae Radix extract solution administered groups compared to the control group. Conclusions: This study shows that the beneficial effect of Morindae Radix extract solution on the concentration, motility and morphology of sperm, the testicular tissues and the activities of sperm hyaluronidase increased the greater the duration the mice were administered it. We suggest that Morindae Radix may be useful for the treatment of male sexual dysfunction and infertility.
