Background: Although recent metagenomic approaches have characterized the distinguished microbial compositions in airways of asthmatics, these results did not reach a consensus due to the small sample size, non-standardization of specimens and medication status. We conducted a metagenomics approach by using terminal restriction fragment length polymorphism (T-RFLP) analysis of the induced whole sputum representing both the cellular and fluid phases in a relative large number of steroid $na{\ddot{i}}ve$ asthmatics. Methods: Induced whole sputum samples obtained from 36 healthy subjects and 89 steroid-$na{\ddot{i}}ve$ asthma patients were analyzed through T-RFLP analysis. Results: In contrast to previous reports about microbiota in the asthmatic airways, the diversity of microbial composition was not significantly different between the controls and asthma patients (p=0.937). In an analysis of similarities, the global R-value showed a statistically significant difference but a very low separation (0.148, p=0.002). The dissimilarity in the bacterial communities between groups was 28.74%, and operational taxonomic units (OTUs) contributing to this difference were as follows: OTU 789 (Lachnospiraceae), 517 (Comamonadaceae, Acetobacteraceae, and Chloroplast), 633 (Prevotella), 645 (Actinobacteria and Propionibacterium acnes), 607 (Lactobacillus buchneri, Lactobacillus otakiensis, Lactobacillus sunkii, and Rhodobacteraceae), and 661 (Acinetobacter, Pseudomonas, and Leptotrichiaceae), and they were significantly more prevalent in the sputum of asthma patients than in the sputum of the controls. Conclusion: Before starting anti-asthmatic treatment, the microbiota in the whole sputum of patients with asthma showed a marginal difference from the microbiota in the whole sputum of the controls.

This paper as basic work on the regional economic policy of Korean government considers economic conditions and fundamentals of the cold started 5+2 mega-regional economic zones and makes a comparative study of regional economic power of national mega-regional economic zones based on the established economic indicator. Therefore, this study aims to consider henceforward policy direction of the mega-regional economic zone and the validity of the regional economic policy, which promote autonomous mega-regional economic zone in dimension to secure the global competitiveness. According to the comparison result of regional economic power index, the capital area had absolute superiority, while Gangwon, Honam and Jeju areas were relatively weak. Since the given regional conditions are dissimilar, the government must consider regional characteristics and economic fundamentals carefully, as they push henceforth regional development policy for the mega-regional economic zone. What is more, the government should promote a balance of the regional development, through to maintain demand-based policy and demand-pull policy flexibly, which are based on demand analysis, as well as unequal quota budget and policy for regions, which are relatively falling behind in terms of development and income.

Versatile Video Coding (VVC), a next-generation video coding standard that is in the final stage of standardization, has adopted various techniques to achieve more than twice the compression performance of HEVC (High-Efficiency Video Coding). VVC adopted Bi-prediction with CU-level Weight (BCW), which generates the final prediction signal with the weighted combination of bi-predictions with various weights, to enhance the performance of the bi-predictive inter prediction. The syntax element of the BCW index is adaptively coded according to the value of NoBackwardPredFlag which indicates if there is no future picture in the display order among the reference pictures. Such syntax structure for signaling the BCW index could violate the flexibility of video codec and cause the dependency issue at the stage of bitstream parsing. To address these issues, this paper proposes an efficient BCW weight signaling method which enables all weights and parsing without any condition check. The performance of the proposed method was evaluated with various weight searching methods in the encoder. The experimental results show that the proposed method gives negligible BD-rate losses and minor gains for 3 weights searching and 5 weights searching, respectively, while resolving the issues.

Objectives：Mental health problems have been found to be more common among juvenile delinquents. This report assessed the reliability, and validity of the MAYSI-2K(Massachusettes Youth Screening Instrument-2 Korean) in Korean delinquents to examine the utility as a screening measure. Methods：The study consisted of 119 male juvenile youths(mean age 16) who admitted in the probation & detention office. They completed an assessment battery including MAYSI-2K and K-YSR(Korean-Youth Self Report) upon entry. Factor analysis, reliability test, and validity test were conducted. Results：The results of factor analysis represented 14 factors which showed more factor structures in comparison with published factor loadings of 7 in the MAYSI. In factor analysis according to the each subscale of the MAYSI, the internal coefficients of 7 subscales ranged from .142 to .756. Test-retest reliability revealed significant correlations(r= .84). There were significant correlations among subscales of MAYSI-2K and K-YSR. Conclusion：Our findings suggested that MAYSI-2K might be a useful screening measure. But further studies with extended number of subjects and culturally appropriate items are required for clinical utility of the MAYSI-2K in Korean delinquents.

Objectives: This study was conducted in order to develop and obtain the nonnative data of the computerized Comprehensive Attention Test(CAT) in Korean children and adolescents. It also aimed to evaluate the reliability and validity of the CAT. Methods: We developed the computerized CAT which includes the selective attention task, the sustained attention to response task, the flanker task, the divided attention task, and the spatial working memory task. We investigated the test-retest reliability and the construction validity of this computerized version by using the data from 21 children, and gathered the nonnative data of 9l2 subjects, aged 4 to 15 years, dwelling in the Metropolitan Seoul area in 2008. Results: No statistical differences between means of the tests and retests of the CAT were observed. The mean of the correlation coefficient of the test-retest scores was 0.715. The results from the factor analyses explained 51.7% of the cumulative variance. In addition, the nonnative data for all of the CAT subtests were obtained. Conclusion: The computerized CAT can be used as a reliable and valid tool in both clinical and research settings for Korean children and adolescents with or without neuropsychiatric conditions such as attention deficit.
