Hydrogenated amorphous Si (a-Si:H), low temperature poly Si (LTPS) 등 기존 thin film transistors (TFTs)에 사용되던 채널 물질을 대체할 재료로써 다양한 연구가 진행되고 있는 amorphous indium-gallium-zinc-oxide (a-IGZO)는 TFT에 적용하였을 때 뛰어난 전기적 특성과 재연성을 나타낼 뿐만 아니라 넓은 밴드갭을 가져 투명소자로도 응용이 가능하다. 본 연구에서는 a-IGZO의 열처리에 따른 소자의 전기적 특성과 조성 분포의 관계를 확인하기 위해 다음과 같이 실험을 진행하였다. Si/SiO2 기판 위에 DC sputter를 이용하여 IGZO를 증착하고 $350^{\circ}C$에서 열처리를 한 후 evaporator로 Al 전극을 형성시켰다. 이 때 전기적 특성의 변화를 비교하기 위해 열처리 한 샘플과 열처리 하지 않은 샘플에 대해 I-V 특성을 측정하였고, 채널 내부의 조성 분포 변화를 transmission electron microscopy (TEM)의 energy dispersive spectrometer (EDS)를 이용하여 관찰하였다. 그 결과 열처리 된 a-IGZO 채널 층의 산소 비율이 감소하였으며 전체적인 조성이 고르게 분포 되었고 전기적 특성은 향상되었다.

Private banking, which is a part of the financial services industry, is an investment advisory business targeting high-net-worth individuals (HNWIs). The demand for asset management services, which isexpanding in the world market as well as in the Asia-Pacific region, is rapidly increasing in Korea as the low-growth, low-interest environment has stabilized. In Korea, the private banking business is ahead of growth, and the evaluation and compensation system of playing institutions remains a challenge. While the aging of the population increases the demand for services, the increasing competition and regulations have decreased the profit margins in the industry. In this paper, a business model is derived from a professional service quality model. Modular advisory services, value-proposition through sophisticated services, and investment expertise with increased clarity would help wealth management firms pursue their opportunities. By interviewing the experts of wealth management banks, this study constructsa business model with elements derived from a relevant literature review. The contribution of this research is to enable these institutions to understand the key factors affecting their financial performances, in order to improve them. This study is limited by one of the research models, and it will be necessary to conduct an empirical test in the future.

This study aims to explore how journalistic norms are practiced in journalists tweets by analyzing journalists' twitter. The study found that journalists consider using twitter as an extension of journalistic practice rather than a private space. In other words, journalists use twitter without a clear distinction about the nature of the twitter. In terms of journalistic norms, journalists expressed actively their opinion rather than keeping the traditional notion of objectivity. There are not much tendency of sharing the gatekeeping role. Also, journalistic use of twitter does not increase transparency as much as expected. However, there is a positive sign of practicing the newly expected journalistic role, conversation with news users. Finally the relationships between journalistic use of twitter and journalistic norms are not straightforward but diverse depending on the size and type of press, and gender of journalists.

우리나라 제조업(製造業)의 수직적(垂直的) 구조(構造)는 선진공업국에 비하여 소(小) 영세기업(零細企業)의 비중이 월등히 높은 피라미드형의 형태를 보이며 80년대말 이후 소기업군의 확대는 더욱 두드러지고 있다. 이처럼 소기업의 비중이 높아진 것은 제조업체들이 가격경쟁력(價格競爭力)을 높이기 위하여 생산비용이 높게 드는 자체생산(自體生産)을 가능한 한 줄이고 임금(賃金)이 낮은 중소기업으로 생산공정을 이양해 왔기 때문이다. 소기업 비중이 높은 분업구조는 가격경쟁력이 중시되어 생산을 분업화해야 하는 경제체제에서는 높은 효율성(效率性)을 발휘한다고 평가할 수 있다. 90년대에 이르러 중소기업이 저가(低價)의 생산요소(生産要素)를 조달받기 어려운 경제여건이 조성되면서 중소기업의 경영불안이 높아지는 등 가격경쟁력을 유지하기 위한 생산분업체제(生産分業體制)는 한계(限界)에 도달한 것으로 보인다. 따라서 대기업과 중소기업간 분업도 기술(技術) 중심의 분업관계(分業關係)로 전환되어야 할 단계에 이르렀다고 볼 수 있다. 그러나 종전과 같이 소기업(小企業)에 의존하는 분업구조(分業構造)로는 기술분업(技術分業)이 정착되기 어렵다. 왜냐하면 연구개발, 전문인력의 고용 등 기술개발과 관련된 기업활동에는 생산량에 관계없이 고정비용(固定費用)이 들어서 기술개발 비용과 위험을 분산시키려면 기업의 생산규모가 상당히 커져야 하기 때문이다. 이는 소기업 중심의 분업구조가 중견기업(中堅企業)중심의 구조로 개편(改編)되어야 함을 의미한다. 중견기업이 육성되려면 첫째, 대기업과 직거래하는 중소업체(中小業體)의 수(數)가 축소되어야 한다. 거래업체수의 과다는 기업규모를 영세하게 만드는 가장 직접적 요인이기 때문이다. 그러나 거래업체의 정리과정에서 기존업체들이 중소기업 보호여론을 등에 업고 반발할 수 있고, 대기업이 교섭력을 강화하기 위한 수단으로 악용할 수 있으므로 객관적이고 투명한 정리기준의 제시가 전제되어야 한다. 둘째, 대기업의 중소기업에 대한 대폭적 자본참여(資本參與)가 허용되어야 한다. 대기업의 자본참여는 중소기업 지배를 강화할 것으로 우려되어 현재는 극히 부분적으로 허용하고 있으나, 개방경제하에서는 대기업과 국내 중소기업간의 협력관계를 유지시키는 효과적 수단으로 작용하게 될 것이다. 셋째, 은행 등 금융자본(金融資本)의 중견기업에 대한 투자(投資) 활성화(活性化)가 필요하다. 금융자율화로 금융기관의 수익성이 강조되는 상태에서 금융자본이 거래업체의 주주(株主)로서 참여하면 경영정보를 손쉽게 파악할 수 있어 우량업체의 신속한 육성이 가능해질 수 있다.

This paper explores the limited role of alliances in preventing maritime territorial disputes among member states, using the ongoing conflict between Greece and Türkiye, two NATO allies, as a case study. Drawing on Institutionalist theory, we seek to explain the mechanisms that have contributed to the failure of the alliance to prevent this dispute, despite constant cooperation and transparency. Unlike land disputes, maritime territorial disputes are complex and multi-layered, with fluid boundaries that can change with climate or natural resource availability. Moreover, the lack of constant surveillance creates ambiguity about territorial encroachment thresholds. These factors have exacerbated the dispute between Greece and Türkiye, drawing other NATO members into the conflict and undermining the strength of the alliance. This paper concludes by providing policy implications for the Republic of Korea in its own potential maritime disputes, and contributes to the broader literature on the role of alliances in preventing territorial disputes.

공정하고 투명한 선거를 이루기 위해서는 비밀성(privacy), 선거권(eligibiligy) 등과 더불어 전체검증(universally verifiability)과 매표방지(receipt-freeness) 속성이 반드시 제공되어야 한다. 그러나 전체검증은 누구나 투표내용을 확인할 수 있는 방법을 제공하는 것이고 매표방지는 투표내용과 투표자를 연결할 수 있는 방법을 차단하는 것으로 두가지 특성은 상호표리적 관계에 있어서 두가지 특성을 동시에 만족시키기가 어렵다. 이 논문에서는 신뢰할 수 있는 제3자인 정직한 랜덤마이저(Honest Randomizer, HR)와 최소한의 물리적 가정인 HR에서 유권자로 가는 도청 불가능한 채널(untappable channel)을 이용하여 전체검증과 매표방지를 제공하는 효율적인 전자선거 기법을 제안한다.

The corporate logo symbolizes the company's value, goals and vision as a visual symbol representing the company. It serves as a communication tool for companies by conveying different messages depending on design and color. As demands for ESG management have recently increased, companies have begun to implicitly demonstrate values such as environmental protection and corporate transparency through logos. Companies use logos as a strategy to visually emphasize the value they pursue and project the desired image as a signal. In this process, stakeholders who see the logo experience cognitive bias. Therefore, this study seeks to find out that ESG value can be indirectly communicated by the design of corporate logos, which can also affect a company's ESG evaluation. In addition, this study will examine the moderate effect that logos expect to encounter a greater bias effect as the companies actively include ESG-related issues in corporate disclosure data. This study conducted an analysis of 617 KOSPI-listed companies using ESG evaluation data from 2020 to 2022. The analysis confirmed the significant relation of the type of logo and ESG disclosure on ESG evaluation but found partially moderate effect of ESG disclosure.

Recently, the proportion of overseas orders of domestic construction companies is increasing, and the global market demands management transparency on corporate social responsibility activities. Therefore, domestic companies are faced with the need to systematically prepare for social responsibility activities. The purpose of this study was to examine whether CSR activities have a moderating effect on the relationship between organizational trust, job satisfaction, turnover intention and contract type. This study analyzed the effect of CSR activities on organizational trust, job satisfaction and turnover intention. The study targets regular and irregular workers in construction companies who promote CSR activities through the homepage, public service ad, and media. The questionnaire distributed 300 copies online. The final valid sample is 255 (145 Regular and 110 Irregular). Empirical analysis used a structural equation model. The results of the study are as follows. First, in CSR activities, economic responsibility, philanthropic responsibility and ethical responsibility had a positive (+) effect on organizational trust. Second, organizational trust had a positive (+) effect on job satisfaction in CSR activities. Finally, the magnitude of the Moderate effect of the type of labor contract according to the group classification showed that the CSR activity on organizational trust had many regular employees with economic responsibility. Also, organizational trust in job satisfaction was found to be large in regular employees. The results of this study can be a guide to CSR activities of construction companies in terms of organizational effectiveness.
