Deep submicron급 CMOS디바이스에서 래치업 면역특성을 향상시키기 위한 새로운 Triple well구조를 제안하였다. Triple well에서 이온주입 에너지와 도즈량 변화에 따른 최적인 래치업 면역을 위한 공정조건을 확립하고 이것을 기존의 Twin well구조와 비교분석하였다. 공정은 공정시뮬레이터인 ATHENA로 소자를 제작하여 도핑프로파일과 구조를 해석하고 래치업 특성은 소자시뮬레이터인 ATLAS를 사용하였다. Triple well과 Twin well의 구조에서 공정상의 차이가 도핑프로파일에 미치는 영향과 프로파일 형태가 래치업 특성에 미치는 영향을 규명하였다. Triple well구조에서 p-well이온주입에너지 2.5MeV, 도즈량 1×10/sup 14/[cm/sup -2/]일 때 트리거 전류가 2.5[mA/${\mu}{m}$]로 매우 큰 래치업 면역특성을 얻었다.

In this paper, a novel triple-mode cavity structure, designed for compactness and operating at 850 MHz, is analyzed. A cylindrical dielectric resonator is loaded into a metallic cylindrical cavity. Previous study has been focused on the analysis of the cylindrical dielectric resonator, but in this paper, the effect of the cylindrical metallic cavity has been analyzed. Enclosing the dielectric resonator inside the metallic cavity increases the resonant frequency of the dielectric resonator; however, this increases the quality factor and introduces the possibility of installing coupling screws. The principle of generation of triple-mode was investigated by parametric analysis. The generated triple-mode is TE011 mode and two orthogonally generated HEM121 modes. By adjusting the radius of the dielectric resonator, the height of the dielectric resonator, or the radius of the cylindrical metallic cavity, three modes could be coincided. However, the height of the metallic cavity keeps three modes separated. The mode characteristics of the proposed cavity are analyzed using a full-wave electromagnetic (EM) simulation. The proposed triple-mode cavity could be developed to triple-mode filter using a coupling screw, and the commercial application for the miniaturized filter below 1 GHz could be expected.

This paper exhibits the concept of Triple Helix model to explain and link university-industry-government (Triple Helix) connections to national innovation systems theory. The driver of this paper is to test the dynamics of Triple Helix concept under national innovation system in the Association of South East Asian Countries (ASEAN)-5 economies. Panel econometric analysis with cross-sectional dependence (CD) test is applied to investigate the relationship amongst Triple Helix variables. The empirical analysis employs innovation indicators of five founding ASEAN countries namely Malaysia, Indonesia, Singapore, the Philippines and Thailand for the period of 2000-2015 from an existing WDI and WCY database. Econometric results support the two research questions of this study; firstly, there is a significant relationship between innovation outcome and its key drivers under Triple Helix context of National Innovation System in ASEAN-5 economies; secondly, the extent of the relationship among government R&D expenditure with high-tech productions are positive and significant while new ideas coming from universities as scientific publications and high-tech production have positive relationship but not significant yet in ASEAN-5 countries. Overall labor productivity is positive and significant with innovation outcomes in ASEAN-5.

Objectives : I intended to find out the origin and development of symptom discrimination based on theory of triple energizers before Tang Dynasty(唐代). Methods : I extracted the topic-related contents from books in this era. After arraying them in a chronological order, I analyzed the materials. Results : The author in Zhong Zang Jing(中藏經) first mentioned that symptom of Huo Luan(霍亂) was deeply related with triple energizers. Ge Hong(葛洪) did not only come out with some symptoms and mechanisms for Shang Han(傷寒) and Za Bing(雜病), but also applied them to their usages for herb medicine. Chao Yuan Fang(巢元方) suggested its symptoms were more closely related with Shang Han and Za Bing than before. For the first time, Chao subdivided its symptoms to both cold-heat and weakness-strength sides. Sun Sai Miao(孫思邈) supplemented its discrimination invented by Chao(巢元方), adding more symptoms and prescriptions for triple energizers. Wang Tao(王燾) showed more prescriptions for triple energizers than before, and initially designed the discrimination for Huo Luan, diabetes(消渴), and epidemic Wen Bing(溫病). Conclusions : Before Tang dynasty, the symptom discrimination based on theory of triple energizers had been originated and developed for the purpose of repairing Za Bing, not just treating Wen Bing.

목적: 본 연구는 보철물의 적합도를 계측하는 두 가지의 측정방법을 평가하기 위해 지르코니아로 전부도재관을 제작하고 replica technique과 triple-scan protocol을 이용하여 전부도재관의 변연 및 내면 적합도를 비교 연구하고자 하였다. 재료 및 방법: 타이타늄의 지대치 모형을 제작하여 20개의 지르코니아 전부도재관을 제작하였다. 제작된 지르코니아 전부도재관 10개는 replica technique을 이용해 복제하고 복제된 시편을 협설, 근원심으로 절단하여 변연 및 내면 적합도를 측정하였고, 다른 10개의 전부도재관은 triple-scan protocol을 이용하여 협설과 근원심으로 단면을 형성하고 변연 및 내면 적합도를 계측하여 통계 분석하였다 (${\alpha}=.05$). 결과: 변연과 내면 적합도는 replica technique $49.86{\pm}29.69{\mu}m$, triple-scan protocol $75.35{\pm}64.73{\mu}m$로 유의한 차이가 있었고 (P < .001), 내면 적합도만을 측정한 결과 각각 $58.38{\pm}31.77{\mu}m$, $64.00{\pm}46.43{\mu}m$로 유의한 차이가 없었다 (P > .343). 결론: Replica technique과 triple-scan protocol을 이용하여 전부도재관의 변연 및 내면 적합도를 비교 측정한 결과 triple-scan protocol에서의 변연 적합도가 크게 측정되었고, 내면 적합도만 비교해 본 결과 통계적인 유의한 차이가 없었다.

Purpose: Triple-positive breast cancer is defined by estrogen receptor, progesterone receptor, and human epidermal growth factor receptor 2 (HER2) positivity. Several systemic breast cancer therapies target hormonal and HER2 responsiveness. We compared clinical outcomes of triple-positive disease with those of HER2-enriched and luminal HER2-negative disease and investigated the clinical efficacy of anti-HER2 therapy for triple-positive disease. Methods: We retrospectively compared overall and recurrence-free survival among cases included in the Korean Breast Cancer Society (KBCS) and Seoul St. Mary's Hospital breast cancer registries and the therapeutic efficacy of trastuzumab for triple-positive and HER2-enriched cases. Results: KBCS registry data (2006-2010; median follow-up, 76 months) indicated that patients with triple-positive breast cancer had intermediate survival between those with luminal A and HER2-enriched subtypes (p<0.001). Trastuzumab did not improve overall survival among patients with triple-positive breast cancer (p=0.899) in contrast to the HER2-enriched subtype (p=0.018). Seoul St. Mary's Hospital registry data indicated similar recurrence-free survival outcomes (p<0.001) and a lack of improvement with trastuzumab among patients with triple-positive breast cancer (median follow-up, 33 months; p=0.800). Multivariate analysis revealed that patients with triple-positive breast cancer had better overall survival than those with HER2-enriched disease and similar survival as those with the luminal A subtype (triple-positive: hazard ratio, 1.258, p=0.118; HER2-enriched: hazard ratio, 2.377, p<0.001). Conclusion: Our findings showed that anti-HER2 therapy was less beneficial for treatment of triple-positive breast cancer than for HER2-enriched subtypes of breast cancer, and the triple-positive subtype had a distinct prognosis.

The Pythagorean theorem and Pythagorean triple are well known. We know some Pythagorean triples, however we don't Cow well that every natural number can belong to some Pythagorean triple. In this paper, we show that every natural number, which is not less than 2, can be a length of a leg(a side opposite the acute angle in a right triangle) in some right triangle, and list some Pythagorean triples.

A directed triple system of order ν, denoted by DTS(ν), is said to be $textsc{k}$-near rotational if it admits an automorphism consisting of exactly three fixed elements and $textsc{k}$ cycles of length (ν-3)/$textsc{k}$. In this paper, we obtain necessary and sufficient conditions for the existence of $textsc{k}$-near rotational DTS(ν)s for every positive integer $textsc{k}$.

An extended Steiner triple system of order v, denoted by ESTS(v), is said to be (f, k)-rotational if it admits an automorphism consisting of exactly f fixed elements and k cycles of length (equation omitted). In this paper, we obtain a necessary and sufficient condition for the existence of (f,2)-rotational extended Steiner triple systems with f=2 and f=3.

In this article, it is proved that under some conditions every bijective Jordan triple product homomorphism from generalized matrix algebras onto rings is additive. As a corollary, we obtain that every bijective Jordan triple product homomorphism from $M_n(\mathcal{A})$ ($\mathcal{A}$ is not necessarily a prime algebra) onto an arbitrary ring $\mathcal{R}^{\prime}$ is additive.
