  • Purpose: At present, there are a variety of serious patient safety incidents related to problems in health information technology (HIT), specifically involving electronic medical records (EMRs). This emphasizes the need for an enhanced electronic medical record system (EMRS). As such, this study analyzed both the nature of and potential to prevent incidents associated with HIT/EMRS based on data from the Korea Patient Safety Reporting and Learning System (KOPS). Methods: This study analyzed patient safety incidents submitted to KOPS between August 2016 and December 2019. HIT keywords were used to extract HIT/EMRS incidents. Each case was reviewed to confirm whether the contributing factors were related to HIT/EMRS (HIT/EMRS-related incidents) and if the incident could have been prevented (HIT/EMRS-preventable incidents). The selected reports were summarized for general clarity (e.g., incident type, and degree of harm). Results: Of the 25,515 obtained reports, 2,664 incidents (10.4%) were HIT-related, while 2,525 (9.9%) were EMRS-related. HIT/EMRS-related incidents were the third largest type of incident followed by 'fall' and 'medication incidents.' More than 80% of HIT/EMRS-related incidents were medication-related, accounting for approximately one-third of the total number of medication incidents. Approximately 10% of HIT/EMRS-related incidents resulted in patient harm, with more than 94% of these deemed as preventable; further, sentinel events were wholly preventable. Conclusion: This study provides basic data for improving EMR use/safety standards based on real-world patient safety incidents. Such improvements entail the establishment of long-term plans, research, and incident analysis, thus ensuring a safe healthcare environment for patients and healthcare providers.

  • HIT Solar Cell은 단결정 실리콘 웨이퍼가 초박막 amorphos 실리콘 층으로 싸여있는 구조이다. HIT Solar Cell에서 amorphos 실리콘의 두께와 도핑 농도는 태양전지의 효율을 결정하는 매우 중요한 요인이다. 본 논문에서는 높은 효율을 갖는 태양전지 설계를 위해 AFORS HET 프로그램을 이용하여 TCO_a-Si:H(p)_a-Si:H(i)_c-Si(n)_Al 구조를 설계했다. 후에 a-Si:H(p)의 두께와 a-Si:H(i) 의 두께를 가변하며 효율을 측정하였고, p-i-n 구조에서 n+ 층을 추가함에 따라 변하는 효율을 측정하였다. 최적화 한 결과 $V_{oc}$ = 693mV, $J_{sc}$ = 3891mA/$cm^{-2}$, FF = 8363%, $E_{ff}$ = 22.55% 의 고효율을 얻었다.

  • The purpose of this study was to characterize the genetic contribution to endothelial adaptation to exercise training. Vasoreactivity was assessed in aortas from four inbred mouse strains (129S1, B6, NON, and SJL) after 4 weeks of moderate intensity continuous exercise training (MOD), high intensity interval training (HIT) or in sedentary controls (SED). Intrinsic variations in endothelium-dependent vasorelaxation (EDR) to acetylcholine (ACh) as well as vasocontractile responses were observed across SED groups. For responses to exercise training, there was a significant interaction between mouse strain and training intensity on EDR. Exercise training had no effect on EDR in aortas from 129S1 and B6 mice. In NON, EDR was improved in aortas from MOD and HIT compared with respective SED, accompanied by diminished responses to PE in those groups. Interestingly, EDR was impaired in aorta from SJL HIT compared with SED. The transcriptional activation of endothelial genes was also influenced by the interaction between mouse strain and training intensity. The number of genes altered by HIT was greater than MOD, and there was little overlap between genes altered by HIT and MOD. HIT was associated with gene pathways for inflammatory responses. NON MOD genes showed enrichment for vessel growth pathways. These findings indicate that exercise training has non-uniform effects on endothelial function and transcriptional activation of endothelial genes depending on the interaction between genetic background and training intensity.

  • The synthesis of the 3D images is the most important part of the virtual reality. The ray tracing is the best method for reality in the 3D graphics. But the ray tracing requires long computation time for the synthesis of the 3D images. So, we implement the ray tracing with software and hardware. Specially we design the hit-test unit with FPGA tool for the ray tracing. Hit-test unit is a very important part of ray tracing to improve the speed. In this paper, we proposed a new hit-test algorithm and apply the parallel architecture for hit-test unit to improve the speed. We optimized the arithmetic unit because the critical path of hit-test unit is in the multiplication part. We used the booth algorithm and the baugh-wooley algorithm to reduce the partial product and adapted the CSA and CLA to improve the efficiency of the partial product addition. Our new Ray tracing processor can produce the image about 512ms/F and can be adapted to real-time application with only 10 parallel processors.

  • In this study, we analyzed the motion animation of game characters, which is a visual part of the game elements for 'Hit Impact'. The game selected for analysis focused on the movements of the characters in the arcade game , which is thought to have a weak 'Hit Impact' and looked for the cause. We also analyzed the differences in the motion of the characters in the home transplant version of , which is considered to have improved 'Hit Impact', compared to the arcade version. As a result of the analysis, it was found that the reason for the weak 'Hit Impact' in the arcade version was mainly due to the wrong timing and judgment of hitting and hitting movements, and at the same time, supplemented physical reactions and stun, camera directing, and hitting effects could have a significant impact on improving 'Hit Impact'.

  • In this study, we collected 39 megalocytiviruses isolated from diseased fish in Korea from 2012 to 2018. Major capsid protein (MCP) gene, a part of vascular endothelial growth factor (VEGF) gene and histidine triad motif-like protein (HIT) genes of Megalocytivirus were targeted for PCR amplification and analysis of those DNA nucleotide sequences. Korean strains revealed two genotypes (red sea bream iridovirus and turbot reddish body iridovirus types) based on the phylogeny of MCP gene. The red sea bream iridovirus type (RSIV-type) megalocytiviruses were divided into RSIV-subgroup 1 and 2. From the phylogenetic analysis of the VEGF genes, a genotypic variant of RSIV-type Megalocytivirus was identified. The HIT-like protein gene was detected in RSIVs, but not in TBRIV and ISKNV, suggesting that HIT-like protein gene may be specific in RSIV.

  • Obesity and fitness have been identified as key health concerns among USA firefighters yet little is known about the current habits related to exercise and diet. In particular, high-intensity training (HIT) has gained increasing popularity among this population but limited quantitative data are available about how often it is used and the relationship between HIT and other outcomes. Using survey methodology, the current study evaluated self-reported HIT and diet practice among 625 male firefighters. Almost one-third (32.3%) of participants reported engaging in HIT. Body composition, as measured by waist circumference and percentage body fat, was significantly related to HIT training, with HIT participants being approximately half as likely to be classified as obese using body fat [odds ratio (OR) = 0.52, 95% confidence interval (CI) = 0.34-0.78] or waist circumference (OR = 0.61, 95% CI = 0.37-0.98). Those who engaged in HIT were more than twice as likely as those who did not (OR = 2.24, 95% CI = 1.42-3.55) to meet fitness recommendations. Findings highlight directions for future prevention and intervention efforts.

  • This paper proposes HWbF(Hit and WLC based Firewall) design which consists of an PFS(Packet Filter Station) and APS(Application Proxy Station). PFS is designed to reduce bottleneck and to prevent the transmission delay of them by distributing packets with PLB(Packet Load Balancing) module, and APS is designed to manage a proxy cash server by using PCSLB(Proxy Cash Server Load Balancing) module and to detect a DoS attack with packet traffic quantity. Therefore, the proposed HWbF in this paper prevents packet transmission delay that was a drawback in an existing Firewall, diminishes bottleneck, and then increases the processing speed of the packet. Also, as HWbF reduce the 50% and 25% of the respective DoS attack error detection rate(TCP) about average value and the fixed critical value to 38% and 17%. with the proposed expression by manipulating the critical value according to the packet traffic quantity, it not only improve the detection of DoS attack traffic but also diminishes the overload of a proxy cash server.
