Recently several recommender systems have been developed in a variety of applications, but providing accurate recommendations that match the preferences and constraints of various users is quite challenging. This paper presents a method of recommending digital products based on the past preference of a user on the price, rating and selling volume of a product. Experimental results of the method with actual data of Amazon showed that the average accuracy of the recommendations made by the method is 85%. Although the results are preliminary, the method is potentially capable of making more accurate personalized recommendations than existing methods.

The present study examines the relative roles of external recommendations and internally felt satisfaction in influencing patient loyalty to a doctor. It establishes that recommendations do result in preliminary loyalty formation in the patient to the doctor, but only until the formation of own experiences; the significance of external sources of recommendation in the determination of patient loyalty becomes insignificant thenceforth. Implications for the doctors are that they should strive at fostering bonds of emotional attachment in their present patients so that they become strongly loyal and spread positive word-of-mouth which could result in the doctor getting new patients as well. Probable extensions of this research are also discussed later in the paper.

The Coronary Artery Calcium Data and Reporting System (CAC-DRS) is a standardized reporting method for calcium scoring on computed tomography. CAC-DRS is applied on a per-patient basis and represents the total calcium score with the number of vessels involved. There are 4 risk categories ranging from CAC-DRS 0 to CAC-DRS 3. CAC-DRS also provides risk prediction and treatment recommendations for each category. The main strengths of CAC-DRS include a detailed and meaningful representation of CAC, improved communication between physicians, risk stratification, appropriate treatment recommendations, and uniform data collection, which provides a framework for education and research. The major limitations of CAC-DRS include a few missing components, an overly simple visual approach without any standard reference, and treatment recommendations lacking a basis in clinical trials. This consistent yet straightforward method has the potential to systemize CAC scoring in both gated and non-gated scans.

Kidney and liver are the major organs of metabolism and excretion of drugs. Renal and Hepatic impairment may affect the pharmacokinetics/pharmacodynamics and the safety of drugs. Adjusting the dosage based on organ function is the essential role of pharmacists. However, differences have been noted on the recommended dosage among the literatures. We compared and analyzed the recommendations of 4 literature sources which are commonly used for dosage adjustment. From April, 2011 to August, 2011, we selected data on recommendations for dosage adjustment for impaired renal and hepatic function of 100 drugs through a protocol. We analyzed the definition terms of renal and hepatic impairment, recommendations for dosage adjustment, evidenced references in four literature sources: Korean National Formulary (KNF), American Hospital Formulary System Drug Information (AHFS), Micromedex (MM) and Drug Prescribing of Renal Failure (DPRF). We further examined the data homogeneity by comparing how drugs that required no adjustment according to one source were categorized by the other. Sources use different definition terms among themselves except DRPF. Presence or absence of evidenced references about renal/hepatic functional states are KNF (0%/0%), AHFS (78%/62.6%), MM (87.5%/65.6%) and DPRF (93.2%/no recommendation) respectively. Recommendations of specific dosage and dosing interval are KNF (24%/13%), AHFS (39.6%/12.1%), MM (50%/17.7%), and DPRF (55.4%/no recommendation) respectively. Regarding the data homogeneity, the differences were remarkable. Drugs with no adjustment according to AHFS were categorized to be adjusted/ contraindicated by KNF, MM, DPRF and the values were (44%/5.6%), (22%/0%), and (36%/0%) in renal function, (39%/6.5%), (19%/3.2%), and (no recommendation/no recommendation) in hepatic function respectively. Our study shows remarkable definite variation in definitions and recommendations about definition terms, information of dosage and interval, presence or absence of evidenced references. Especially for KNF, quantitative recommendations on dosages and dosing intervals should be made in the near future. To maximize the drug effect and safety and to minimize the heterogeneity of the literature sources, reviewing at least two sources are suggested when recommending the proper dosage adjustment based on organ function.

Objective: The purpose of this study is to investigate the effect of personality type on human performance tool compliance in nuclear power plants (NPPs) and to propose general recommendations for an enhancement of its practical utilization. Background: Various guidelines, regulating criteria, and recommendations have been developed to prevent human errors in NPPs. Despite these efforts, the accidents sometimes caused by human errors have steadily occurred, and therefore, various human performance tools have been adopted as countermeasures against human errors. The major and inevitable contributing factors among the many hazards to human errors might be the trait and personality, which are considered to be the inner world of humans. Thus, we try to investigate the utilization of human performance tools by considering the different types of operating crew personalities, and we suggested more practical recommendations to prevent human errors according to the personality. Method: We developed the Questionnaire using the Big 6 (HEXACO) models, which are human performance tools for workers in NPPs, and individual (condition) variables to investigate the effect of personality types on human performance tools. We slightly modified them to help the survey respondents understand them better. A survey was conducted for ordinary people over the age of 20. SPSS 22.0 was used to perform a correlation analysis and a hierarchical regression analysis to find the relationship between personality types and human performance tools. Results: The utilization of human performance tools shows significant differences statistically by personality. The correlation result reveals that the types of Honesty (H), Extraversion (X), Conscientiousness (C), and Openness to experience (O) show a higher utilization of human performance tools. In hierarchical regression results, human performance tools of task preview, questioning attitude, stopping when unsure, self-checking, effective communication, and place-keeping show a higher utilization with personality types. However, the Agreeableness (A) type did not show significant differences statistically with human performance tools. Conclusion: We tried to investigate the utilization of human performance tools by considering the different types of human personality and provide more practical recommendations to prevent human errors according to the personality. These results will be able to prevent human errors owing to the characteristics (advantages and disadvantages) of personality types. Application: This information can be utilized as guidelines for proactive recommendations according to the workers' personalities for more practical human performance tools to prevent human errors in an NPP.

BACKGROUND/OBJECTIVES: This study aimed to evaluate how breastfeeding and complementary nutrition practices of mothers of 0-24-month-old children comply with the World Health Organization (WHO) recommendations for infant and young child feeding and to compare the results with selected demographic parameters related to the mother and child. SUBJECTS/METHODS: The research sample comprised mothers (n = 250) with children less than 2 years old. Data were obtained via questionnaire and were analyzed using SPSS 20.0 package program. The Pearson χ² or Fisher's exact tests were used for assessing relationships between categorical variables. The one-sample t-test was used for comparisons with reference values. RESULTS: Most mothers (97.2%) breastfed their babies immediately after birth. The mean time to breastfeeding after delivery was 47.8 ± 14.8 minutes, and 40.8% of the mothers complied with the WHO recommendation. Furthermore, 59.8% of the mothers exclusively breastfed their children for 6 months (mean 5.2 ± 1.5 months). The mean duration to the start of providing complementary food was 5.8 ± 0.6 months, and 76.1% of mothers who complied with the WHO recommendation. Only 12.3% of mothers breastfed their children for at least 12 months (mean 7.7 ± 3.3 months). On average, mothers gave cow milk to their children for the first time at 10.1 ± 1.7 months and honey at 11.8 ± 2.3 months. The mothers' rates of compliance with the WHO recommendations on cow milk and honey feeding were 32.0% and 71.6%, respectively. The rate of mothers who complied with the WHO minimum meal frequency recommendation was 88.3%. CONCLUSIONS: We suggest that the WHO recommendations on this subject will be realized more fully by emphasizing the importance of the positive effects of breastfeeding until the age of 2 years and of a timely start of complementary food provision. Such changes will affect child health over the long term.
