  • In the current years, it has now become necessary to establish standards for micronutrient intake based on scientific evidence. This review discusses issues related to the development of the 2020 Dietary Reference Intakes for Koreans (KDRI) for magnesium (Mg), zinc (Zn), and copper (Cu), and future research directions. Following issues were encountered when establishing the KDRI for these minerals. First, characteristics of Korean subjects need to be applied to estimate nutrient requirements. When calculating the estimated average requirement (EAR), the KDRI used the results of balance studies for Mg absorption and factorial analysis for Zn, which is defined as the minimum amount to offset endogenous losses for Zn and Mg. For Cu, a combination of indicators, such as depletion/repletion studies, were applied, wherein all reference values were based on data obtained from other countries. Second, there was a limitation in that it was difficult to determine whether reference values of Mg, Zn, and Cu intakes in the 2020 KDRI were achievable. This might be due to the lack of representative previous studies on intakes of these nutrients, and an insufficient database for Mg, Zn, and Cu contents in foods. This lack of database for mineral content in food poses a problem when evaluating the appropriateness of intake. Third, data was insufficient to assess the adequacy of Mg, Zn, and Cu intakes from supplements when calculating reference values, considering the rise in both demand and intake of mineral supplements. Mg is more likely to be consumed as a multi-nutrient supplement in combination with other minerals than as a single supplement. Moreover, Zn-Cu interactions in the body need to be considered when determining the reference intake values of Zn and Cu. It is recommended to discuss these issues present in the 2020 KDRI development for Mg, Zn, and Cu intakes in a systematic way, and to find relevant solutions.

  • Background: The incidence of chronic obstructive pulmonary disease (COPD) is increasing and the disease is becoming an important cause of morbidity and mortality worldwide. It is important to implement evidence-based guidelines by primary care physicians (PCPs) to establish qualified management of COPD patients. The aim of this survey is to investigate the pattern of COPD management among PCPs and to apply it to the development of Korean COPD guidelines. Methods: A web-based questionnaire was prepared that consisted of 25 questions on the pattern of COPD management. A total of 217 PCPs participated in the survey from June 2006 to May 2007. Results: Many PCPs (61.8%) possessed a spirometer, but the application rate was relatively low (35.8%) and more than half of the COPD patients (57%) did not receive a diagnosis based on spirometry. Administration of oral medication was preferred than the administration of inhaled medication for both stable COPD and acutely exacerbated COPD. More than 90% of the PCPs endorsed educational measures to quit smoking and vaccinate against influenza. It was noted that 56.7% of the PCPs were aware of the GOLD guidelines, but only 7.3% tended to fully implement the recommendations of the guidelines in daily practice. Conclusion: The results of the survey indicate that despite the high awareness rate of the current COPD guidelines, deficits exist among the PCPs with respect to the diagnosis and treatment of COPD. The results of this survey should be applied for the development of new COPD guidelines in order to decrease the discrepancy between the guidelines and the daily practice of the PCPs.

  • This study examines the impact of government funds to venture capital on investment in early-stage firms. We provide novel explanations about this relationship focusing on mechanisms by which government funds influence the perceived uncertainty, decision about investment priority, scale economy of investment, information asymmetry in investment decision, and capital expense. We argue that venture capital's investment in early-stage firms increases as government funds increase and as government funds are explicitly directed for early-stage firms. However, we further claim that the impact of government funds on early-stage investment will be decreasing as their size increases and finally be reverted to negative impact beyond a certain amount of funds to show inverse-U relationship. Our empirical examination using data from 105 Korean venture firms active as of 2013 consistently supports the claims. This study contributes to the venture capital literature by providing novel arguments about mechanisms and effects of policy intervention in venture capital. In practice, we expect our results will provide an opportunity for relevant policy makers to review their venture support policy based on empirical evidences for policy effects.

  • This study examined the status of studies on exercise interventions for middle-aged women with chronic low back pain that had been conducted over the past 10 years (2005-2014) in Korea. The existing reports were searched electronically using the database of RISS, National Assembly Library, KISS, and DBpia with the key words of middle-aged women, chronic low back pain, exercise, and exercise program. Finally, 12 articles were included in the review. One article was from nursing science, and 11 were from other disciplines. In a qualitative evaluation on the papers, 1 study scored 8 out of 10 points, 8 studies scored between 5-6 points, and 3 studies scored 3-4 points. Intervention sessions were conducted for 55 minutes, on average, each at a frequency of 3.1 sessions per week, for a total of 29.7 sessions. This study found that lumbar neuromuscular exercise, yoga exercise, and aquatic exercise were effective in rehabilitation in middle-aged women with chronic low back pain. In the future, these findings are expected to be used in nursing intervention for the establishment of the basis for evidence-based nursing practice.

  • Objectives : This study was done to assess the effects of the clinical interchange between the Western Medicine and the Oriental Medicine for ischemic stroke patients. The patient outcomes include changes in neurologic function by modified NIH stoke scale, stroke pattern identification scale, and patient satisfaction, Methods : For the assessment of effects, this study was performed with 178 inpatients who had undergone the stroke care at three hospitals (W Hospital adopted western therapy, S Oriental Hospital adopted Sasang constitution medicine therapy, and H Oriental Hospital adopted mixed therapy according to a joint protocol on Western Oriental medical care) from November 1997 to December 1998. Patients were interviewed or written with self-entered questionnaire forms, and clinical data were obtained, Physicians or oriental doctors wrote clinical questionnaire forms according to the care process. Results : The patient outcomes within three hospitals at 2 stages (at admission and discharge in the modified NIH stroke scale. at admission and second weeks during admission in the stroke pattern identification scale) were found to be decreased, Especially in the results of hierarchical multiple regression analysis, the degree of improvement of modified NIH stroke scale of the stroke patients at W Hospital was significant large than it at S Oriental Hospital. Also, the degree of improvement of stroke pattern identification scale at W Hospital was significantly large than it at other two hospitals. However, the patient's satisfaction score at three hospitals wasn't significantly different. Conclusions : The result of this study suggested that the joint clinical research of Western & Oriental medical practitioners was possible even if there was a conflict between Western Medicine and Oriental Medicine. Therefore Western & Oriental medical practitioners share a mutual responsibility to apply evidence-based practice, to seek scientific empirical proof through randomized clinical trials between the multicenter.

  • Background: As a common and essential contrast medium at present, gadobenate dimeglumine has shown better performance than some other agents when applied to Breast Magnetic Resonance Imaging Screening (Breast MRI Screening). Nevertheless, reports on the diagnostic performance of these two mediums (gadobenate dimeglumine and gadopentetate dimeglumine) are not completely consistent. Objective: To assess the diagnostic value of gadobenate dimeglumine and gadopentetate dimeglumine for Breast MRI Screening in patients suffering from breast cancer and to provide more convinced evidence to guide clinical practice in terms of appropriate contrast agents. Data Sources and Review Methods: Original articles in English and Chinese published before January 2013 were selected from available databases (The Cochrane Library, PUBMED, EMBASE, Chinese Biomedical Literature Database, Chinese Scientific Journals Full-text Database, Chinese Journal Full-text). The criteria for inclusion and exclusion were based on the standard for diagnosis tests. Meta-Disc software (Version 1.4) was used for data analysis. Then, the area under curve (AUC) of SROC and the spearman rank correlation of sensitivity against (1-specificity) were calculated. Results: Total of 17 researches involving 1934 patients were included. The pooled sensitivity of gadobenate dimeglumine and gadopentetate dimeglumine were 0.99 (0.97, 1.00) and 0.93 (0.88, 1.00) respectively. The pooled specificity for these two contrast agents were 0.924 (0.902, 0.943) and 0.838 (0.817, 0.858) respectively, and the AUC of SROC curve were 0.9781 and 0.9215 respectively. Conclusions: Gadobenate dimeglumine can be regarded as a more effective and feasible contrast medium for Breast MRI Screening. At least 5% differences in diagnostic performance are usually considered as clinically relevant.

  • The purpose of this study was to investigate evidence-based practice (EBP) for sensory integration (SI) intervention in children with cerebral palsy (CP) through a systematic review and meta analysis. The screening strategy was performed to select studies for analysis after that, a meta-analysis was implemented for calculating the effect size (ES) in group studies. Twenty-four studies were included for a systematic review and included seven case reports, three single-subject designs, and fourteen group experimental design studies(three randomized controlled trials, three two groups nonrandomized studies, and six one group nonrandomized studies). The ES of the experimental group studies was moderate size of 0.272. The results of the ES according to the dependent variables, the ES was the largest in the fine motor development. The effect size of the published papers was greater than the unpublished paper's and two groups nonrandomized studies' size effect was the largest in the design. The ES of the infants was larger than the children. The ES for a period of 8 weeks, the number of five times a week, and time in 90 minutes showed the biggest in SI program. Although the ES of SI intervention in children with CP showed moderate effect, accumulation of research well be needed.

  • Purposes: The purpose of this study was to evaluate the extent of performance on activities in critical pathway (CP) according to eight domains and six admission days on nursing records of patients who received total hip replacement surgery. Methods: We reviewed 90 nursing records of patients who received total hip replacement surgery from June, 2004 to July, 2005 at C University Hospital. Data were collected using Hong's CP (2002) and were analyzed using ANOVA. Results: The domain of diet was valued the highest in CP performance scoring, followed by the domains of assessment, activities, and test. There were differences in the performance scores according to the period of admission in all of the domains. Among 132 activities in the CP, 18 activities were completely performed, of which most included activities belonging to the domain of assessment on the admission day. Twelve activities were never performed, of which most included activities belonging to the domain of treatment on the day of operation and the first day after operation. Conclusions: Therefore, further studies on the development of a new system to increase CP utilization and on updating the contents of CP from the best practice based on evidence is recommended.

  • Purpose: This study was done to identify the effectiveness of the 'intervention - mother's recorded song' on low-birth weight infants in an neonatal intensive care unit (NICU). Methods: This study was conducted with a nonequivalent control group pre-posttest quasi-experimental design and the participant group was low-birth weight infants who were admitted to the NICU. Forty-eight infants, 24 in each from two groups, the experimental and control group, participated in the study. Results: For physical response according to vital signs, there were no significant statistical differences in heart rate, respiration rate and pulse oximetry saturation between the experimental group and the control group. For behavioral state, there was a significant statistical difference between the experimental and control group. Conclusion: The study results indicate that the intervention using mother's song had some significance as a nursing intervention with positive impacts. Such an intervention can help pediatric nurses improve infants' stabilization of their vital signs and behavioral states. By showing the effectiveness of such an intervention, the results of this study provide further evidence-based information in developing the practice of pediatric nursing.
