본 논문에서는 Debye 분산 특성을 가지는 복제 방지용 PUF를 설계하기 위한 전자계 해석 방안을 고려하였다. 공기층과 유전체 기판 위에 형성된 분산매질(Si)로 구성된 1차원 모델 내에 전파하는 펄스를 모형하기 위해 FDTD법을 이용하였다. 불연속 경계면에 도달한 펄스는 일부 반사되고 일부는 투과되어 빠르게 감쇠되는 것으로 나타났다. 그 결과 FDTD법에 의한 유전체 기판을 고려한 Debye 분산특성을 가지는 1차원 복제방지용 PUF 모델링에 적용 가능한 것을 확인하였다. Electromagnetic analysis to design unclonable PUFs with frequency-dependant materials with Debye dispersion was considered. To simulate FDTD calculations consider that 1-D problem of pulsed plane wave traveling in free space normally incident on air-silicon material interface on dielectric substrate. The pulse traveling wave at a vacuum-medium interface was reflected, and transmitted wave was dissipated. As a result, 1-D PUF modeling with Debye dispersion on dielectric substrate structure can be applied and FDTD calculation for PUF modeling is a good approximation.

Stimulated thyroglobulin measured 6-12 months after thyroidectomy and radioactive iodine remnant ablation is a very useful guidance for risk-stratification. Thus, this parameter should be a main variable of strategy for follow-up in such patients. Serum Tg and TgAb measurement at the time of ablation just after total thyroidectomy could give a helpful data supporting stimulated Tg measured 6-12 months after radioactive iodine remnant ablation and should be considered in your own follow-up strategies.

Titanium has many special characteristics such as specific high strength, low elastic modulus, excellent corrosion and oxidation resistance, etc. Beta titanium alloys, because of their good formability and strength, are used for jet engines, and as turbine blades in the automobile and aerospace industries. Low cost beta titanium alloys were developed to take economic advantage of the use of low-cost beta stabilizers such as Mo, Fe, and Cr. Generally, adding a trace of boron leads to grain refinement in casted titanium alloys due to the pinning effect of the TiB phases. This study analyzed and evaluated the microstructural and mechanical properties after plastic deformation and heat treatment in boron-modified Ti-2Al-9.2Mo-2Fe alloy. The results indicate that a trace of boron addition made grains finer; this refinement effect was found to be maintained after subsequent processes such as hot forging and solution treatment. This can effectively reduce the number of required manufacturing process steps and lead to savings in the overall cost as well as low-cost beta elements.

Urinary disturbance is deficit in volitional control of voiding. Stroke can cause temporary or permanent urinary disturbance. The purpose of this study was to confirm the effect of Jasin-hwan on urinary disturbance as heat syndrome. This study was carried out on 3 patients with urinary disturbance caused by stroke. We measured components of IPSS (international prostate symptom score) at pre-treatment and post-treatment. After prescribing medication to the patients, symptoms improved rapidly within three weeks. These results support that Jasin-hwan is effective in reduction of urinary disturbance as heat syndrome.

Cardiac diseases are the most common life-threatening diseases in the world. The present study aimed to identify the common and disease-specific signatures for various cardiac diseases by using interspecies microarray sets. By meta-analysis of the datasets, we found 106 common differentially expressed genes (DEGs) between humans and mice. The common DEGs were further examined using various methods such as functional enrichment analysis, randomized network analysis,and cluster-network analysis. By analysis of 11 functional clusters, we obtained 12 highly sensitive common cardiac disease-associated genes that had never been identified before. To examine the sensitivity of the genes to the cardiac pathology, junctate-transgenic (TG) mice with cardiac hypertrophy and arrhythmias symptoms were used. The study led to the identification of eight positive genes (i.e., Synpo2l, Pros1, Crlf1, Col3a1, Frzb, Tm9sf3, Prdx4, and Ltbp2), highly upregulated in the TG mice. Cluster and network analysis showed that the cell survival and death network (cluster 7),extracellular network (cluster 9), and inflammation network (cluster 11) are cardiac disease-specific clusters. We also found that transforming growth factor-β signaling was closely related to the common signatures and that necrosis factor-κB signaling was a core pathway for inflammatory dilated cardiomyopathy. Taken together, our data provide a comprehensive analysis method to identify common and disease-specific signatures.
