  • Seven diagnosis-related groups (DRGs) prospective payment system is going to expand to all hospitals including university hospitals this year. However there are few studies on the change of practice pattern under prospective payment system in the university hospital setting. So This study was intended to predict the practice pattern change after the introduction of 7 DRGs prospective payment system in a university hospital setting. To predict the change of practice pattern, this study used simulation technique. Five hundred and nineteen patients classified as 5 DRGs in a university hospital were selected for simulation. The change of practice pattern were predicted based on clinicians' opinion. We also predicted payment change by service items. Major findings of this study are as follows. First, the total medical payment was reduced by 14.4%. The drug payment change (8.8%) took most of total payment reduction. The followings are the change of treatment material cost (3.2%), the change of laboratory tests cost (1.8%), the change of room charge (0.5%), and other payment change (0.1%), respectively. Second, most of the reduction in total medical payment resulted from the decreased amount of medical services themselves. The transfer of medical services to outpatient setting took up only 4.9% of the total payment reduction. The change of unit price or composition took up 5.5% of the total payment reduction. In this study we found that it is possible to reduce the inpatient services through practice pattern change in university hospital setting. However, it needs to be careful to adjust DRG payment after the reduction of provided services, because most of reduction was not due to service transfer but to service volume reduction. It is desirable to utilize the saving from practice pattern change as incentive to improve quality of care.

  • This study is on the image evaluation of the hair up-style and the wedding dress styles of prospective brides. Based on some prior theoretical studies, and information obtained from wedding magazines and interviews conducted at the beauty business places, four kinds of the hair up-style were selected, namely, top-point, golden-point, back-point, and nape point. Three styles of necklines were selected: boat necklines, V-necklines, and off-shoulder necklines. The surveyor herself did the hair styling for models, and dressed up the models, to produce the stimuli. And the stimuli were presented to percipients along with questionnaires for measuring the image evaluations. Prepared were total 12 different kinds of stimuli, in which four hair up-styles and three dress styles were combined into 12 combinations ($3^*4$), and, with respect to these 12 stimuli, 26 itemized questions were included in the questionnaire. From the factor analysis on the image evaluation of the hair up- style and wedding dresses, five factors were derived as fallowing: attractiveness, boldness, purity, cuteness, feminity. This study revealed that wedding dress styles are more sensitive to the contemporary trend, compared to the hair styles; and the selection in the wedding style is quite influenced by the dress style, but not by the hair up-style. Also, prospective brides evaluated the hair up-styles and the wedding dress styles separately without recognizing their mutual relationship, and thus did not recognize the two as the mutually coordinated relationship, but rather recognize the two as two separate elements.

  • Objective: Egg consumption has been suggested to increase the risk of colorectal and some other cancers. The present study summarized and quantified the current evidence relating dietary intake of eggs and prostate cancer. Materials and methods: Literature searches were conducted to identify peer-reviewed manuscripts published up to July 2012. Twenty manuscripts from nine cohort studies and 11 case-control studies were identified. Summary risk estimates with 95% confidence intervals (CIs) were calculated for case-control and cohort studies separately. Results: Neither the case-control not the cohort studies showed any association of prostate cancer incidence with egg consumption (case-control studies: odds ratio 1.09, 95% CI 0.86-1.31; cohort studies: relative risk 0.97, 95% CI 0.97-1.07). The results were consistent in subgroup analysis. Furthermore, no association was observed between egg consumption and prostate cancer-specific mortality. Conclusions: Our analyses provided no evidence of a significant influence of egg consumption on prostate cancer incidence and mortality. However, more studies, particularly large prospective studies, are needed.

  • This study empirically examined the effects of filial piety on motivations for parenthood among Vietnamese and Korean college students, who represent a generation of young adults and prospective parents in both countries. The Vietnamese data were collected from 325 college students enrolled in three universities located in Hanoi and Korean data were collected from 216 students from a single large university in Seoul. Student respondents were asked to complete the self-administered questionnaire including 'Filial Piety Scale' and 'Motivations for Parenthood Scale.' The results revealed that the Vietnamese students reported a significantly higher level of 'general filial piety' than their Korean counterparts. Vietnamese and Korean participants showed no significant difference in total motivations for parenthood. Among the five sub-factors of motivations for parenthood, however, the Vietnamese students were more likely to place a value on the expansion of self-motivation while their Korean counterparts considered the motivation to strengthen biological family ties to be more salient. Finally, after controlling for sociodemographic characteristics, hierarchical regression analysis revealed that the more filial Vietnamese and Korean college students were towards their parents, the more child-related motives they held in general. The results are discussed in relation to each country's degree of modernization and to recommend prospective family planning and population policies in Vietnam based on the experiences of Korea industrialization.

  • In the more than 100 genome wide association studies (GWAS) conducted in the past 5 years, more than 250 genetic loci contributing to more than 40 common diseases and traits have been identified. Whilst many genes have been linked to a trait, both their individual and combined effects are small and unable to explain earlier estimates of heritability. Given the rapid changes in disease incidence that cannot be accounted for by changes in diagnostic practises, there is need to have well characterized exposure information in addition to genomic data for the study of gene-environment interactions. The case-control and cohort study designs are most suited for studying associations between risk factors and occurrence of an outcome. However, the case control study design is subject to several biases and hence the preferred choice of the prospective cohort study design in investigating geneenvironment interactions. A major limitation of utilising the prospective cohort study design is the long duration of follow-up of participants to accumulate adequate outcome data. The GWAS paradigm is a timely reminder for traditional epidemiologists who often perform one- or few-at-a-time hypothesis-testing studies with the main hallmarks of GWAS being the agnostic approach and the massive dataset derived through large-scale international collaborations.

  • Assessing response to therapy allows for prospective end point evaluation in clinical trials and serves as a guide to clinicians for making decisions. Recent prospective and randomized trials suggest the development of imaging techniques and introduction of new anti-cancer drugs. However, the revision of methods, or proposal of new methods to evaluate chemotherapeutic response, is not enough. This paper discusses the characteristics of the Response Evaluation Criteria In Solid Tumor (RECIST) version 1.1 suggested in 2009 and used widely by experts. It also contains information about possible dilemmas arising from the application of response assessment by the latest version of the response evaluation method, or recently introduced chemotherapeutic agents. Further data reveals the problems and limitations caused by applying the existing RECIST criteria to anti-cancer immune therapy, and the application of a new technique, immune related response criteria, for the response assessment of immune therapy. Lastly, the paper includes a newly developing response evaluation method and suggests its developmental direction.

  • Objectives: The aim of this study is to review and analyze the trends in prospective clinical research (PCR), project, clinical study protocol of Korean medicine (KM) for dementia. Methods: We searched PCRs of KM on dementia in six electronical databases, up to January 28, 2021. Moreover, the clinical research protocol and projects of KM for dementia were searched. Results: Total eight PCRs, nine projects, and three clinical study protocols were included. In the PCRs, there were one randomized controlled trial, five before and after study, and two comparative group before-after studies. Four of them used herbal medicine, two used acupuncture, one study used both herbal medicine and acupuncture, and the other one used moxibustion. Jowiseungchung-tang was the most frequently used herbal medicine. BL62, KI6 were used in electro-acupuncture, auricular-Shenmen in auricular acupuncture, and GV20 in moxibustion. The most frequent outcome was Korean-Dementia Rating Scale (K-DRS). One reported significant increase in K-DRS score, one reported 60% improvement, and the other studies mostly reported no significant difference. In the projects including 20 clinical studies of dementia, herbal medicine, integrative medicine and acupuncture were mainly used. In the protocols, herbal medicine, complex KM intervention, and integrative medicine were used. Conclusions: Currently, the number of PCRs of KM for dementia is very scarce. Therefore, the researcher's interest in this field and national research support should be made more, and the quality of clinical research in the future can be further improved by supplementing the limitations of previously published clinical research.

  • Aminoglycosides are frequently used antibiotics in children. The multiple daily dosing (MDD) in infants and children is twice or three times daily depending on age. Recent studies in adults have shown that once daily dosing (ODD) maximizes the bactericidal activity and might minimize the toxicity of antibiotics. So, I reviewed many studies about efficacy, toxicity and cost effectiveness of ODD of aminoglycosides in children. Most studies suggest that ODD compared with MDD of aminoglycosides is theoretically more efficacious and has no higher toxicity in infants and children. But, the total number of patients included in the studies is not large. Multi-center, controlled prospective studies are required in larger numbers of infants and children to determine the efficacy and safety of the ODD regimen in children before ODD of aminoglycosides can be recommended for routine use.
