Haplotypes for 12 Y-chromosomal STR loci in a Korean population (the central region)

Haplotypes and allele frequencies of 12 STR loci included in the PowerPlex Y system (DYS391, DYS389I, DYS439, DYS389II, DYS438, DYS437, DYS19, DYS392, DYS393, DYS390, and DYS385a/b) were obtained from a sample of 569 unrelated individuals living in the central region of Korea. A total of 473 haplotypes were observed in the 569 individuals studied, of which 426 (90.06%) were unique. The overall haplotype diversity for the 12 Y-STR loci was 0.9985, and the discrimination capacity was 0.8313. In DYS439, we found a new intermediate-sized allele that added an A at base 3 upstream from the repeat region's first GATA motif. The allele was named 11 (U3Ains) according to its sequence structure.     

An Explosion of a CNG Fuel Vessel in an Urban Bus

Abstract: An investigation is presented of the explosion of a CNG (compressed natural gas) fuel vessel, called a liner, in an urban bus. The explosion happened at a gas station 10 min after filling was completed. There were no traces of soot and flames at the failed liner, which would be indicative of explosion by ignition of the gas. The filling process of the station was automatically monitored and recorded in a computer. There was no unusual record of the filling system that indicated excess pressure at the time of the accident. There were cracks on the liner that were initiated at the outer surface of the cylindrical shell located at a point 4 cm above the lower dome where cracks did not originate easily as a result of overload. Chemical analysis was performed on a specimen that was cut from the liner, and there was no peculiarity in the mix. Mechanical analysis was performed on the specimens and showed that the hardness was not in the specified range because of inadequate heat treatment of the metal. The hardness of the liner was strictly controlled in the manufacturing process. All the liners that were manufactured at the same period with the failed liner were recalled for examination.     

东亚电子贸易区及电子贸易税制的构建

东亚地区的相互依赖程度日益加深 ,为了促进东亚地区的贸易便捷化 ,使用信息和通讯技术工具构建电子贸易区成为一种必然。在东亚地区建立PAA等电子贸易区是可取的 ,为了建立电子贸易区 ,有必要改进电子商务的法律和税收制度。为了准备对电子商务进行税收激励 ,政府必须营造出一种能够使电子商务得以蓬勃发展的财政氛围 ,而不必单纯考虑其维护公平、可预测的税收体系的职责     

Microscopic Age Estimation from the Anterior Cortex of the Femur in Korean Adults*

Abstract: The purpose of this study was to develop age‐predicting equations from the anterior cortex of the femur of Korean adults. Seventy‐two femoral samples (44 male and 28 female) were obtained from Korean cadavers and used to develop the equations. The thin sections (<100‐μm thick) were prepared by manual grinding; the sections were not decalcified and were stained with Villanueva bone stain reagent. Analysis of covariance showed no significant differences in age‐adjusted histomorphological variables between sexes. In stepwise regression analysis, osteon population density, average osteon area, and the most anterior cortical width were selected for an age‐predicting equation which produced a high regression correlation (R² = 0.789). The average Haversian canal area was not significantly related to age for any specimen.

Work-Family Conflict and Intimate Partner Violence in the South Korean Military: Mediating Role of Aggression and Buffering Effect of a Counseling Resource

The objective of the current study was to identify the relationship between work-family conflict (WFC) and intimate partner violence (IPV) among military personnel, and verify the mediating role of aggression and buffering effect of a counseling resource. A total of 293 married Korean Air Force personnel were surveyed using a self-administered questionnaire; their responses were analyzed with a structural equation model. The major findings were that 36.9 % of respondents have perpetrated IPV, the prevalence of verbal violence was 33.4 % and physical violence was 16.0 %. Aggression mediated the important part of the association between WFC and IPV. Also, presence of a counseling resource attenuated the relationship between WFC and aggression. The findings suggest that it is necessary for the military to build a personnel counseling system to prevent spouse abuse, develop professional counseling services, and accurately identify aggression tendencies among military personnel.
