Grid-Enabled Parallel Simulation Based on Parallel Equation Formulation

Bojan Andjelkovic,Vančo B. Litovski,Volker Zerbe 한국전자통신연구원 2010 ETRI Journal Vol.32 No.4

Parallel simulation is an efficient way to cope with long runtimes and high computational requirements in simulations of modern complex integrated electronic circuits and systems. This paper presents an algorithm for parallel simulation based on parallelization in equation formulation and simultaneous calculation of matrix contributions for nonlinear analog elements. In addition, the paper describes the development of a grid interface for a parallel simulator that enables a designer to perform simulations on distant computer clusters. Performances of the developed parallel simulation algorithm are evaluated by simulation of a microelectromechanical system.

A key engine for the growth of the culture industry can be found at the development of specialized strategic products. For Korea’s southwestern coastal area, where Mokpo takes a central position, the possibility of such products may be found from culture-related islands and their marine resources. Among the many candidates, the theme of ocean heroes may be the most powerful asset to increase its cultural competitiveness via its potential for global recognition. In this thesis, I have tried to find new possibilities for the area’s specialized strategic industry by focusing on the Ocean’s Worldwide Heroes Park, an amusement park planned from such a viewpoint. Planned according to the necessity to promote public awareness of the value of ocean, the Ocean’s Worldwide Heroes Park aims to raise a “global workforce” through the discovery of the latent maritime assets in Korea and achieve commercial success as a theme park. What is noteworthy regarding the plan is that the world’s ocean heroes are divided into three categories: (a) the heroes who pioneered the world oceans, (b) the heroes who guarded the oceans during the wars, and (c) the heroes in history and folk tales. Also, the park is divided into six zones each of which offers an opportunity to experience an encounter with ocean heroes of the world. As for the exhibitions and productions, content and stories are regarded as more important than other elements, and ‘imagineering’ more essential than engineering. Considering that the development of content is a crucial factor for the success of the park, I concluded that even the first step of planning should progress side by side with the effort to develop visual content and characters. The development of content focused on the world’s ocean heroes and the local culture of the Korea’s southwestern region could lead to the birth of creative and globally competitive cultural products. 베트남의 국제항구 Van Don : 베트남 영토의 북동부와 남서부에는 두 개의 만이 있다. 이 지역은 지리적, 경제적, 전략적으로 상당히 중요한 의미를 갖는다. Tonkin만이 동남아시아지역에서 역사적, 문화적, 경제적으로 중요한 의미를 지니는 반면, Thailand만은 동남아시아의 많은 나라들뿐만 아니라 인도와 서아시아 지역의 많은 나라들과 연관되어 있다. Tonkin만은 126,250㎢의 면적을 가지는 동남아시아의 가장 큰 만 중의 하나로 동부해의 중요한 지역이다. Tonkin만의 경제적, 환경적, 문화적 잠재력을 HaLong의 해양문화를 널리 알리는데 공헌했다. Ha Long문화와 함께 DongSon문화는 외부의 다른 세계들과 밀접한 연관성을 지니는데, 특히 중국의 동남부지역과 일본의 RyuKyu와 Kyushu군도, 동남아시아의 여러 나라의 해양문화와 긴밀한 관련을 갖는다. 반면에 기원 이후 상품을 교환하거나 전도를 목적으로 상인들과 선교사들이 GiaoChau로 들어왔고, 중국문명과 인도문명이 만나는 교량지점으로 번성해 나갔다. 1149년에 Ly Anh Tong은 외국 상인들과의 교역을 목적으로 Van Don을 건설했고, 그 이후 Van Don은 선박과 상품을 점검하기 위한 항구로서 지리적 방어 지역으로 항구로서의 입지를 탄탄히 하며 베트남의 중요한 국제무역항이 되었다. Ly, Tran 그리고 Le왕조에 이르기까지 Van Don은 많은 인구를 가진 생산활동이 활발한 역사적, 종교적 체계를 갖춘 지역으로 7세기 동안 여러 왕조의 상당한 관심을 끌었던 번성한 자주독립체였다. Van Don은 역사상 가장 오래된 무역항이며, 해안이나 강가에 위치한 Van Ninh, Mong Cai, Cat Ba, Yen Hung 등의 항구와 Red River삼각주와 중국 동남부지역의 전통적인 수공예 마을들과 밀접한 연관성을 가지고 있다. 역사적 고고학적 자료에 근거하여 이 논문은 역사적으로 중요한 항구들의 특징들을 체계화하고 Van Don지역의 국가적, 국제적, 경제적 활동과 그 역할을 분석하는데 중점을 두고자 한다.

The Distribution of Information through Online Meeting after COVID-19: Examining the Effect of Past Behavior

Van Hao HOANG(Van Hao HOANG ),Van Vien VU(Van Vien VU ),Quang Truong NGO(Quang Truong NGO ) 한국유통과학회 2023 유통과학연구 Vol.21 No.8

Purpose: Online meeting is chosen instead of face-to-face conferences as a solution that ensures both effectiveness and legality during times of strong epidemic outbreaks. In the current period, managers can have different types of meeting options for information distribution. This study has examined the effect of past behavior on the managers’ intention of organizing online meetings. Research design, data and methodology: Data were collected from a survey with 475 managers and put into SmartPLS 4.0 for analysis. Partial least squares structural equation modeling (PLS-SEM) was employed to test relationships in the research model. Results: The findings indicated that past behavior plays the most critical role in explaining the organizing online meeting intention of managers, followed by attitude and subjective norms. Meanwhile, the perceived behavioral control factor has absolutely no effect on intention in the context of this study. Notably, attitude and subjective norms also remarkably mediated the impact of past behavior on managers’ intention. Conclusions: This study has added to the understanding of the meeting organization behavior of managers. Even if the epidemic is under control, the administrators should still organize some meetings in the form of online because it will affect the social perceptions of future behavior and behavioral intention.

Atomically thin p–n junctions with van der Waals heterointerfaces

Lee, Chul-Ho,Lee, Gwan-Hyoung,van der Zande, Arend M.,Chen, Wenchao,Li, Yilei,Han, Minyong,Cui, Xu,Arefe, Ghidewon,Nuckolls, Colin,Heinz, Tony F.,Guo, Jing,Hone, James,Kim, Philip Nature Publishing Group, a division of Macmillan P 2014 Nature nanotechnology Vol.9 No.9

Semiconductor p–n junctions are essential building blocks for electronic and optoelectronic devices. In conventional p–n junctions, regions depleted of free charge carriers form on either side of the junction, generating built-in potentials associated with uncompensated dopant atoms. Carrier transport across the junction occurs by diffusion and drift processes influenced by the spatial extent of this depletion region. With the advent of atomically thin van der Waals materials and their heterostructures, it is now possible to realize a p–n junction at the ultimate thickness limit. Van der Waals junctions composed of p- and n-type semiconductors—each just one unit cell thick—are predicted to exhibit completely different charge transport characteristics than bulk heterojunctions. Here, we report the characterization of the electronic and optoelectronic properties of atomically thin p–n heterojunctions fabricated using van der Waals assembly of transition-metal dichalcogenides. We observe gate-tunable diode-like current rectification and a photovoltaic response across the p–n interface. We find that the tunnelling-assisted interlayer recombination of the majority carriers is responsible for the tunability of the electronic and optoelectronic processes. Sandwiching an atomic p–n junction between graphene layers enhances the collection of the photoexcited carriers. The atomically scaled van der Waals p–n heterostructures presented here constitute the ultimate functional unit for nanoscale electronic and optoelectronic devices.

Purpose: Transanal total mesorectal excision (TaTME) was developed to overcome surgical difficulties experienced in distal pelvic dissection. Concerns have been raised about potential worse postoperative functional outcomes after TaTME. Also, the oncological safety was questioned. This study aimed to describe the functional, surgical, oncological outcomes and quality of life (QoL) after TaTME. Methods: All consecutive TaTME cases for rectal cancer without disseminated disease between December 2016 and April 2019 were included. The Wexner incontinence score, low anterior resection syndrome (LARS) score, fecal incontinence-related QoL, and the European Organisation for Research and Treatment of Cancer Quality of Life Questionnaire-core questionnaire and 29-item module (EORTC QLQ-C30/CR29) were collected. Kaplan-Meier analysis was used to calculate local recurrence-free survival. Results: Thirty patients were eligible for analysis of which 23 received questionnaires. Response rate was 74%. After a median follow-up of respectively 20.0 and 23.0 months for functional and oncological outcomes, the median (interquartile range) of Wexner incontinence and LARS scores were 9.0 (7.0–12.0) and 33.1 (25.0–39.0). Major LARS was present in 73.3%. Fecal incontinence, general and colorectal-specific QoL subdomains that are associated with poor bowel function scored in line with previously reported data. The 2-year actuarial cumulative local recurrence rate was 3.7% (95% confidence interval, 2.4%–5.0%). Conclusion: TaTME may lead to significant functional impairments. Patients should receive preoperative counseling on this topic and be fully aware of the potential consequences of their treatment. Oncological data were in line with other short- to moderate-term data and did not show alarming results.
