  • The qualify of preschool education is related to the qualify of the physical environment, This research is aiming to develop and validate the set of scales for the measurement of physical quality of the interior spaces in child care facilities. The research has been in three major phases: (1)the development of indicative sub-scales for the description, measurement and evaluation of the physical designed quality of early childhood environments (2)two rounds of iterative phases of reliability and validity testing of the scales through expert panels and observational field-testing and (3)implications for future research to be done. 13 sub-scales were developed, which are based on Moore's 15 design principal for child care environments. And each sub-scale includes several evaluation items based upon developmental theory, existing empirical literature, and Korean, Australian and American child care standards. This set of scales will (1)aid research on the effects of environmental variables on quality of child care facilities for infants, toddlers, and preschoolers; (2)permit evaluation of such environments to identify areas of needed improvement; and (3)provide information for policy makers, parents, administrators, and designers/architects.

  • Purpose: Globally, falls are a major public health problem. The study aimed to evaluate the predictive validity of the Timed Up and Go test (TUGT) as a screening tool for fall risk. Methods: An electronic search was performed Medline, EMBASE, CINAHL, Cochran Library, KoreaMed and the National Digital Science Library and other databases, using the following keywords: 'fall', 'fall risk assessment', 'fall screening', 'mobility scale', and 'risk assessment tool'. The QUADAS-II was applied to assess the internal validity of the diagnostic studies. Thirteen studies were analyzed using meta-analysis with MetaDisc 1.4. Results: The selected 13 studies reporting predictive validity of TUGT of fall risks were meta-analyzed with a sample size of 1004 with high methodological quality. Overall predictive validity of TGUT was as follows. The pooled sensitivity 0.72 (95% confidence interval [CI]: 0.67-0.77), pooled specificity 0.58 (95% CI: 0.54-0.63) and sROC AUC was 0.75 respectively. Heterogeneity among studies was a moderate level in sensitivity. Conclusion: The TGUT's predictive validity for fall risk is at a moderate level. Although there is a limit to interpret the results for heterogeneity between the literature, TGUT is an appropriate tool to apply to all patients at a potential risk of accidental fall in a hospital or long-term care facility.

  • The relationship between H. pylori(Hp) infection and recurrent abdominal pain(RAP) in children is not clear. Current data in the literature regarding a causal relationship between Hp infection and childhood RAP are conflicting. However, meta-analysis and most of the recently published studies have not supported an association between Hp infection and an increased prevalence of abdominal pain. Most published studies have some problems and have been criticized on methodological grounds. Most of the existing studies have not been designed to include double-blind placebo controls. And, because of the low incidence of Hp infection in children, they have a problem of obtaining sufficient numbers of the Hp infected children. There is also a concern about the heterogeneity of testing methodology in the studies and diagnostic accuracy problems of the non-invasive tests such as low sensitivity of the serology tests and false positive results of the UBT in children. And conflicting results may be explained, in part, by the poor definition of RAP or dyspepsia for the study subjects. To date, no consensus exists for the treatment of Hp-infected children with RAP. Some authors suggest the clinical efficacy of Hp. But others suggest that eradication of Hp is not associated with improvement of RAP. The problem of the most treatment studies is that they had usually no control groups and the number of the subjects was small. In order to make reasonable decisions about treatment of Hp infection in children with RAP, long-term, randomized, double blind, well controlled studies in large numbers of children will be required.

  • Background: Low-level laser therapy (LLLT) including laser acupuncture (LA) has been widely used to treat chronic low back pain (CLBP), but there is no critically appraised evidence of the potential benefits. The purpose of this protocol for a systematic review was to enable the evaluation of the effectiveness of LLLT including LA for non-specific CLBP to identify the potential benefits. Methods: The electronic databases MEDLINE (PubMed), Embase (Ovid), the Cochrane Central Register of Controlled Trials (CENTRAL), Korean medical databases (KoreaMed, KMBASE, KISS, NDSL, KISTI, OASIS), the Chinese database (CNKI), and Japanese databases (CiNII, J-STAGE) are recommended. Results: Randomized controlled trials in LLLT including LA should be included in the searches. All data synthesis and subgroup analyses should be conducted using a Review Manager software. The Cochrane risk of bias tool can be used to evaluate methodological quality of the studies. A risk ratio or mean difference with a 95% confidence interval will show the effects of LLLT including LA. Conclusion: The primary outcome would be pain intensity and functional status/disability due to low back pain. The secondary outcome would be a global measurement of recovery or improvement, quality of life and adverse event.

  • 본 논문에서는 기개발된 간선도로 연동화 신호최적화 모형인 KS-SIGNAL의 최적화 수행속도를 향상시키기 위한 새로운 모형식을 개발하였다. 이를 위하여 기존 모형식의 수정, MILP 최적화 루틴의 탑재, 좌회전 현시순서와 관련한 제약식의 추가 등 3단계에 걸친 모형 개선 작업이 이루어졌으며, 그 결과 기존 모형식과 비교 99%이상의 최적화 수행시간 단축 효과를 창출하였다. 개발된 KS-SIGNAL 모형식은 여러 다양한 경우에 대해 모의실험을 실시한 결과 교통량보다는 교차로간 거리에 더욱 민감하게 반응함으로써 지체최소화모형 (TRANSYT-7F)보다는 통과폭최대화모형(PASSER-II)에 더 가까운 신호시간계획을 산출하였다. 더불어 본 모형식이 좌회전 현시순서를 최적화시키지 못하는 TRANSYT-7F 모형식과 통과폭을 최대화하나 통과폭 밖의 직진교통류를 고려하지 못하는 PASSER-II 모형식, 그리고 이들의 단점을 상호보완한 결합모형과 비교하여 더 적은 지체를 유발시키는 보다 더 효율적인 신호시간계획을 창출하는 것으로 분석되었다.
