The demineralized bone matrix (DBM) as the bone graft material to increase the fusion rate was widely used in spinal fusion. The current study aimed to compare the fusion rate of DBM to the fusion rate of autograft in lumbar spine fusion via meta-analysis of published literature. After systematic search, comparative studies were selected according to eligibility criteria. Checklist (risk of bias assessment tool for non-randomized study) was used to evaluate the risk of bias of the included nonrandomized controlled studies. The corresponding 95% confidence interval (95% CI) were calculated. We also used subgroup analysis to analyze the fusion rate of posterolateral lumbar fusion and lumbar interbody fusion. Eight studies were finally included in this meta-analysis. These eight studies included 581 patients. Among them, 337 patients underwent spinal fusion surgery using DBM (DBM group) and 204 patients underwent spinal fusion surgery with mainly autologous bone and without using DBM (control group). There was no significant differences of fusion rate between the two groups in posterolateral fusion analysis (risk ratio [RR], 1.03; 95% CI, 0.90-1.17; p=0.66) and interbody fusion analysis (RR, 1.13; 95% CI, 0.91-1.39; p=0.27). Based on the available evidence, the use of DBM with autograft in posterolateral lumbar spine fusion and lumbar interbody fusion showed a slightly higher fusion rate than that of autograft alone; however, there was no statistically different between two groups.
대중국거래에서 수하인의 상품인수거절에 대한 해상운송인의 법적대응
한상현(Han SangHyun) 한국상품학회 2007 商品學硏究 Vol.25 No.1
In this study, I presented some reason of consignee"s freight nonacceptance and the ocean carrier`s legal countermeasures on rejection of goods by China`s consignee that often happen in visible trade with China.<BR> The main reasons that chinese consignees refuse the receipt of goods are as follows; First, damage of freight and sudden tumble of market price. Second, consignee"s trade control legislation violation. Third, receiving refusal of freight by sales contract. Fourth, delayed arrival of bill of lading (B/L). Fifth, defect of shipping documents. By legal countermove that sea carter can take about China consignee"s freight nonacceptance, there is following thing. First, freight discharging in warehouse or appropriate place. Second, disposal of freight through event of lien. Third, deposit of freight. Fourth, disposal with receiving of freight by customhouse. 본 연구는 재중국 무역거래에서 종종 발생하는 수하인의 화물인수거절사유와 이 경우 중국법상 해상운송인이 취할 수 있는 대응조치들을 법리적으로 분석함과 동시에 이러한 법적대응조치들의 실무상 효용성과 적용가능성을 일본과 한국법의 비교를 통해 시사점을 도출하고자 한다. 중국에 있어 수하인의 화물인수거절의 주요사유로는 화물의 손상과 시황가격의 급격한 하락, 수하인의 무역관리법규 위반, 매매계약상 화물의 수취거부, 선하증권(B/L)의 연착, 선적서류의 하자 등이 있으며, 이 경우 취할 수 있는 해상운송인의 법적대응조치들로는 화물을 창고 또는 적당한 장소에 양하, 유치권의 행사를 통한 화물의 처분, 화물의 공탁, 세관에 의한 화물의 수취 및 처분 등이 있다.

Amplified fragment length polymorphism (AFLP) is one of molecular marker technique based on DNA and is extremely useful in detection of high polymorphism between closely related genotypes like Korean wheat cultivars. Six Korean wheat cultivar specific marker sets have been developed from inter simple sequence repeat (ISSR) analysis and we can identify the 13 Koran wheat cultivars form other cultivars using six that (Son et al., 2013). We used four combinations of primer sets in our AFLP analysis for developing additional cultivar specific markers in Korean wheat. Twenty-one of the AFLP bands were isolated from ACG/M-CAC primer combination and 19 bands were isolated from E-AGC/M-CTG primer combination, respectively. We used forty bands to design sequence characterized amplified region (SCAR) primer pairs for Korean wheat cultivar identification. Only one of 40 amplified primer pairs, C2, were able to use for wheat cultivar identification. The DNA band of 215bp length was amplified by C2 primer pairs in ten cultivars, Eunpa, Olgeuru, Gobun, Saeol, Milsung, Sinmichal, Jokyung, Sugang, Goso, and Joah. Then C2 primer was applied to these primer sets as newly SCAR marker, six cultivars are identifying from other cultivars, additionally. Finally, to use the C2 and six primer sets, 19 Korean wheat cultivars are identified.

Characteristics of agronomy, especially good yield productivity is very important in wheat (Triticum aestivum L.) as human food crop. Development of elite cultivar having good traits is required for food stability. In 2013, a new wheat line called Iksan370 has been developed by the National Institute of Crop Science, RDA. Iksan370 has hard red winter wheat characteristics and better features like resistance to biotic, abiotic stress and higher yield ability than Keumkang. Heading and maturing date were delayed about ten days and period to flowering date was shorter three or four days than Keumkang. Culm and spike length of Iksan370 were 95cm and 15.3cm, averagely. This means that culm and spike length were longer than Keumkang (79cm and 7cm, respectively). It showed higher milling rate (75.5%), protein content (13.5%) and SDS-sedimentation volume (77.5ml) than Keumkang. Genotypes of six genes, GBSSA, B, D, PPO18, Pina and Pinb, were represented that were similar to Keumkang, respectively. Average yield of Iksan370 in the preliminary trial test was 6.61 tons/ha in upland. We expect that yield productivity and farm income were increased by Iksan370.
