Objectives This systematic review aimed to provide evidence of the effectiveness and safety of manual therapy for asthma in children and adolescents. Methods We queried eight electronic databases (PubMed, Ovid-MEDLINE, EMBASE, The Cochrane Library, CNKI, ScienceON, KISS, and RISS) up to the end of April 2022. We included only randomized controlled trials (RCTs) investigating manual therapy for the treatment of asthma in children and adolescents. The methodological quality of the included RCTs was evaluated using the Cochrane risk-of-bias tool 1.0. Results Four RCTs were eligible for inclusion. Meta-analysis could not be performed due to the heterogeneity of the studies. One study showed the statistical significance of SMD 0.41 (95% CI: 0.06, 0.76, p<0.05) in the comparison with the osteopathic therapy group and the sham control group before and after treatment on the same day of peak expiratory flow. Conclusions This possibility was observed in a non-pharmacological approach to manual therapy. Manual therapy can be considered as an adjunct therapy for asthma treatment in children and adolescents who have difficulty with drug therapy.

Purpose: Diabetes Mellitus (DM) is a leading cause of death with a prevalence rate of 12.4% in South Korea. Self-management is crucial for patients with DM, because many studies have reported that self-management intervention based on the Health Belief Model (HBM) is effective. The purpose of this study was to investigate the current state of HBM based intervention studies and the components and effects of the theories used in the study for diabetes patients. Methods: A systematic review was conducted using the Pubmed, Cochrane Library and Embase databases from January 2009 to May 2019. We reviewed characteristics of intervention based on the HBM in randomized controlled clinical trials (RCTs), quasi-experimental study intervention. Results: Eight studies published in English between 2009 and 2019 were included in this review. The key components of the health behavior promotion program applied to the DM patients were perceived susceptibility, perceived severity, perceived benefits, perceived barriers and self-efficacy. The intervention based on these components has reported to significantly increase the health behavior change, likelihood of taking health action and improve physiological indicators (HbA1c, and fasting blood sugar etc.). Conclusion: This study highlighted the importance of intervention programs based on the HBM for DM patients.

Useful genes can be Screened from various environments by construction of metagenomic DNA libraries. In this study, water samples were collected from several lakes in mid Korea, and analyzed by T-RFLP to examine diversities of the microbial communities. The crude DNAs r were extracted by the SDS-based freezing-thawing method, and then further purified using an $UltraClean^{TM}$ kit (MoBio, USA). The metagenomic libraries were constructed with the DNAs partially digested with EcoR I, BamH I, and Sac II in Escherichia coli DH 10B using the pBACe3.6 vector. About 44.0 Mb of metagenomic libraries were obtained with average inserts 13-15 kb in size. The bphC genes responsible for degradation of aromatic hydrocarbons via mets-cleavage were identified from the metagenomic libraries by colony hybridization using the bphC specific sequence as a probe. The 2,3-dihydroxybiphenyl (2, 3-DHBP) dioxygenase gene (bphC ), capable of degradation of 2,3-DHBP, was cloned and its nucleotide Sequences analyzed. The genes consisted of 966 and 897 base pairs with an ATG initiation codon and a TGA termination codon. The activity of the 2,3-DHBP dioxygenase was highly expressed to 2,3-DHBP and Showed a broad substrate range to 2,3-DHBP, catechol, 3-methylcatechol and 4-methylcatechol. These results in-dicated that the bphC gene identified from the metagenomes derived from lake water might be useful in the development of a potent strain for degradation of aromatic pollutants.

FIR 필터에서 곱셈기는 대부분의 면적을 차지한다. FIR 필터의 설계시 개별적인 곱셈기 대신 Common Subexpression Elimination(CSE) 알고리즘을 이용하여 덧셈만으로 곱셈기를 구현할 수 있다. CSE방식은 곱셈을 이용하지 않기 때문에 보다 작은 면적으로 필터를 구현할 수 있으나 덧셈에서 발생하는 캐리의 긴 전파 시간으로 인하여 필터 연산시간이 길어지는 단점이 있다. 특히 더해지는 항의 쉬프트가 클수록 부호 확장이 많아지며 부호확장에 의해 덧셈의 면적이 커지고 계산 시간이 길어진다. 본 논문에서는 CSE 알고리즘에서 부호 확장 부분을 제거하는 방법을 제안하며 제안한 알고리즘을 이용하여 주어진 예제를 삼성 0.35u 공정으로 설계하였을 때 기존 설계 방법 보다 면적, 속도, 파워소모에서 각각 17%, 31%, 12% 의 이득이 있음을 보인다.

One of the characteristics of academic writing is the inclusion of citations and references. As the development of reference styles used for international scholarly communication has mostly been led by Western academic societies, the reference styles developed in Western nations do not reflect the characteristics of Korean names. As a result, it is hard to distinguish Korean authors through citations based on Western reference styles, which in turn decreases the retrieval efficiency of relevant authors and ultimately the efficiency of scholarly communication. This paper intends to analyze author name disambiguation of Korean authors indicated according to Western reference styles. It aims to suggest the necessity for enhancing name disambiguation of Korean authors and revision of reference styles. Its ultimate goal is to increase the efficiency of scholarly communication through the improvement of name disambiguation of Korean authors. For this purpose, this study collected and analyzed name data of Korean researchers and compared name disambiguation of authors by reference style. Based on research results, this study confirmed a necessity for revising reference styles to improve name disambiguation of authors and suggested a necessity for research into the improvement of plans for revision.
