Humanity is experiencing a very fast-paced technological evolution. As technological systems evolve exponentially, societies are becoming more global and are starting to have impacts beyond their geographic demarcations. This implies that, the actions of a person who is across the ocean from where we live could have significant impacts on our everyday lives. This article explores the complexity of globalization, identifies a number of global issues, and looks at the University and the Science and Technology Parks as potential sources of human capital to tackle current and forthcoming global challenges, ranging from new energy sources to potable water distributions. The article focuses on current efforts that are taking place across universities and science and technology parks around the world. We propose a new methodology whereby interdisciplinary work can inform the development of multidisciplinary approaches to solve some of the most complex global issues such as cyber security and educating the next generations of global leaders, providing them them with the necessary skills to be successful in a globally distributed workforce.

With improving computing performance, various digital platforms are being developed to enable easily utilization of high-performance computing environments. EDISON 1.0 is an online simulation platform widely used in computational science and engineering education. As the research paradigm changes, the demand for developing the EDISON 1.0 platform centered on simulation into the EDISON 2.0 platform centered on data and artificial intelligence is growing. Herein, a data framework, a core module for data-centric research on EDISON 2.0 digital platform, is proposed. The proposed data framework provides the following three functions. First, it provides a data repository suitable for the data lifecycle to increase research reproducibility. Second, it provides a new data model that can integrate, manage, search, and utilize heterogeneous data to support a data-driven interdisciplinary convergence research environment. Finally, it provides an exploratory data analysis (EDA) service and data enrichment using an AI model, both developed to strengthen data reliability and maximize the efficiency and effectiveness of research endeavors. Using the EDISON 2.0 data framework, researchers can conduct interdisciplinary convergence research using heterogeneous data and easily perform data pre-processing through the web-based UI. Further, it presents the opportunity to leverage the derived data obtained through AI technology to gain insights and create new research topics.

한국의 고등직업교육은 40년의 발전 끝에 기초적인 발전에서 질적인 발전으로의 전환으로 이미 칭찬할 만한 성과를 거두었다. 중국의 고등직업교육원은 개혁개방을 거쳐 많은 양의 양질의 기술기술인재를 각 분야로 이송하였다. 고등직업교육은 중국 교육제도의 필수불가결한 부분으로서 "고품질", "실용" 및 "기능성" 인재를 양성하는 중요한 능력으로 경제 및 사회 발전에 큰 기여를 한다. 이와 함께 소작농, 가사도우미, 퇴직근로자 등 상대적으로 기능이 낮은 근로자의 고용스트레스가 증가하고 있다. 이러한 배경에서 고등 교육은 실업 문제를 해결하고 강력한 인적 자원을 사회에 제공하기 위해 국가 정책을 안내하고 지원하는 데 필수적이다.

이 글은 국제교육교류의 성격을 밝히고, 그 가능성을 살펴본 것이다. 이 목적 달성을 위해 우선 국제교육교류라는 것은 국가 간 교육에 대한 교류를 함으로써 경제적으로 낙후한 지역에 대한 지원과 더불어 국가들 간의 상호이해에 기반해 전 세계의 발달에 기여하는 것에서 그 의미를 찾을 수 있는 것이다. 다음으로 국제교육교류에 대한 현황을 교육부, 국립국제교육원, 경남교육청 국제교육교류센터의 내용을 살펴보았다. 이들 세 주체에 나타난 국제교육교류에 대한 현황에서는 실천적인 측면에서 활동을 하고 있지만, 이들을 이론화하여 설명이나 예측을 행하는 것에는 한계가 보이기도 하였다. 이러한 것을 토대로 국제교육교류의 가능성은 정부나 교육청의 실천력 강화는 교육의 타율성을 가져올 수 있고, 자원이 부족한 나라에 대한 지원을 통해 해당 국가의 성장에 기여할 수 있으며, 개발도상국에 개발 원조에 대한 제한성이 있고, 우리나라 학문적 발전에 대한 저조한 노력이 있고, 연구방법론의 활성화를 통한 학문 정체성의 확립에 대해 논의하였다.

본 논문에서는 Delay Tolerant Network(DTN)에서 Markov chain으로 노드의 속성 정보를 분석하여 노드의 이동경로를 예측하는 알고리즘을 제안한다. 기존 DTN에서의 예측기반 라우팅 기법은 노드가 미리 정해진 스케줄에 따라 이동하게 된다. 이러한 네트워크에서는 스케줄을 예측할 수 없는 환경에서 노드의 신뢰성이 낮아지는 문제가 있다. 본 논문에서는 이러한 문제를 극복하기 위해 노드의 속성 정보를 Markov chain을 적용하고 일정 구간에서 시간에 따른 노드의 이동 경로를 예측하는 CMCP(Context-awareness Markov-Chain Prediction)알고리즘을 제안한다. 제안하는 알고리즘은 노드의 속성 정보 중 노드의 속력과 방향성을 근사한 후 Markov chain을 이용하여 제한된 주기와 버퍼의 범위에서 확률전이 매트릭스를 생성하여 노드의 이동 경로를 예측하는 알고리즘이다. 주어진 모의실험 환경에서 노드의 이동 경로 예측을 통해 중계 노드를 선정하여 라우팅 함으로써 메시지 전송 지연 시간이 감소하고 전송률이 증가함 보여주고 있다.

Design and syntheses of four red phosphorescent heteroleptic cationic iridium(III) complexes containing two substituted phenylquinoxaline (pqx) or benzo[b]thiophen-2-yl-pyridin (btp) main ligands and one 2,2'-biimidazole (H2biim) ancillary ligand are reported: [$(pqx)_2$Ir(biim)]Cl (1), [$(dmpqx)_2$Ir(biim)]Cl (2), [$(dfpqx)_2$Ir(biim)]Cl (3), [$(btp)_2$Ir(biim)]Cl (4). Complex 1 showed a distorted octahedral geometry around the iridium(III) metal ion with cis metallated carbons and trans nitrogen atoms. The absorption, emission and electrochemical properties were systematically evaluated. The complexes exhibited red phosphorescence in the spectral range of 580 to 620 nm with high quantum efficiencies of 0.58 - 0.78 in both solution and solid-state at room temperature depending on the cyclometalated main ligands. The cyclic voltammetry of the complexes (1-3) showed a metal-centered irreversible oxidation in the range of 1.40 to 1.90 V as well as two quasi reversible reduction waves from -1.15 to -1.45 V attributed to the sequential addition of two electrons to the more electron accepting heterocyclic portion of two distinctive cyclometalated main ligands, whereas complex 4 showed a reversible oxidation potential at 1.24 V and irreversible reduction waves at -1.80 V.

A new series of heteroleptic cyclometalated iridium(III) complexes has been synthesized and characterized by absorption, emission and cyclic voltammetry studies: $(pqx)_2Ir(acac)$ (1), $(dmpqx)_2Ir(acac)$ (2) and $(dfpqx)_2Ir(acac)$ (3) where pqx=2-phenylquinoxalinate, dmpqx=2-(2,4-dimethoxyphenyl)quinoxalinate, dfpqx=2-(2,4-difluorophenyl) quinoxalinate and acac=acetylacetonate anion. The reaction of excess acetylacetone with ${\mu}$-chloride-bridged dimeric iridium complex, $[(C\^N)_2Ir({\mu}-Cl)]_2$, gives a complex 1 and an unusual hydridoiridium(III) complex, $(pqx)IrH(acac)_2$ (4). The complex 1, 2 and 3 show their emissions in an orangered region (${\lambda}_{PL,max}$ = 583-616 nm), and the emission maxima can be tuned by the change of substituent at phenyl ring of 2-phenylquinoxaline ligand. The phosphorescent line shape indicates that the emissions originate predominantly from $^3MLCT$ states with little admixture of ligand-based $^3({\pi}-{\pi}^*)$ excited states. The structures of complex 3 and 4 are additionally characterized by a single crystal X-ray diffraction method. The complex 3 shows a distorted octahedral geometry around iridium(III) metal ion. A strong trans influence of the phenyl ring is examined. In complex 4, there are two discrete molecules which are mirror images each other at the ratio of 1:1 in an unit cell. We propose that the phosphorescent complex 1, 2 and 3 are possible candidates for the phosphors in OLEDs applications.

Many plant species have two modes of reproduction: sexual and asexual. Both modes of reproduction have often been viewed as adaptations to temporally or spatially variable environments. The plant should adjust partitioning to match changes in the estimated success of the two reproductive modes. Perennial plants showed that favorable habitats in soil nutrients or water content tend to promote clonal growth over sexual reproduction. In contrast, under high light-quantity conditions, clonal plants tend to allocate more biomass to sexual reproduction and less to clonal propagation. On the other hand, plants with chasmogamous and cleistogamous flowers provides with a greater tendency of the opportunity to ensure some seed set in any stressful environmental conditions such as low light, low soil nutrients, or low soil moisture. It is considered that vegetative reproduction has high competitive ability and is the major means to expand established population of perennial plants, whereas cleistogamous reproduction is insurance to persist in stressful sites due to being strong. Chasmogamous reproduction mainly enhances established and new population. Therefore, the functions of sexual and asexual propagules of perennial or annual plants differ from each other. These traits of propagule thus determine its success at a particular region of any environmental gradients. Eventually, if environmental resources or stress levels change in either space or time, species composition will probably also change. The reason based on which the plants differ with respect to favored reproduction modes in each environmental condition, may be involved in their specific realized niche.
