올해 광주지역 광산업체의 총 매출액은 당초 목표로 했던 8,500억원을 훨씬 상외 할 것으로 예측되고 있다. 하반기에 계획된 시장개척단과 국내외 전시회를 통해 광산업들의 추가적인 매출이 이어진다면 1조억 원을 상외 할 수 있을 것이라 조심스럽게 내다보고 있다. 이는 국내.외 댁내 광가입자망( FRRH) 시장을 겨냥한 광통신 부품기업들이 그 어느 해 보다 공격적인 경영에 나선 결과로 풀이되고 있다. 여기에 발광 다이오드(LED) 경관조명 등 반도체 조명업체와 응용업체들의 선전도 광주 광산업계에 활력을 불어넣어 준 것으로 분석되고 있다.

OLED 조명은 점이나 선광원 뿐 아니라 넓은 면적의 패널조명도 구현이 가능해 두께 2~3mm의 초슬림 제품도 제작할 수 있고, 눈부심도 거의 없어 은은한 빛이 필요한 실내조명에 적합하다. 그리고 수은 납 등 중금속을 사용하지 않고 친환경 유기소재를 이용한 발광다이오드로 양극구조의 면광원 조명으로 차세대 환경친화적인 조명이며, 에너지 절감효과가 우수한 고효율 특성을 갖고 있어 LED 조명과 함께 기존 조명을 대체할 차세대 광원으로 주목을 받아 왔다. 본 고에서는 OLED 조명의 산업구조와 시장전망 및 국내외 업체들의 개발현황을 분석하고자 한다.

OLED는 유기발광 물질에서 나오는 빛을 이용하는 소자로 현재는 주로 디스플레이분야에서 LCD와 경쟁하고 있다. OLED 조명은 백색을 내는 OLED 소자를 조명으로 이용하는 것으로 휘도가 높고 낮은 전압에서 구동되며 유리 기판위에 제작됨으로 얇다는 장점을 가지고 있다. 특히 OLED는 수 mm 이하의 두께로 구현이 가능하여 경량 박형의 광원이 가능하므로 실치 장소에 대한 제약이 거의 없다는 장점을 까지고 있다. 시장전망 기관들에 따르면 OLED 조명 시장은 2012년을 전후로 본격적으로 시작될 것으로 예상하고 있다.

The drybulk shipping market has high freight rate volatility in the chartering market and various and complex factors affecting the market. In the unstable economic situation caused by the COVID-19 pandemic in 2020, the BDI plunged due to a decrease in trade volume, but turned from the end of 2020 and maintained a booming period until the end of 2022. The main reason for the market change is the decrease in the available fleet that can actually be operated for cargo transport due to port congestion by the COVID-19 pandemic, regardless of the fleet and trade volume volatility that have affected the drybulk shipping market in the past. A decrease in the actual usable fleet due to vessel waiting at port by congestion led to freight increase, and the freight increase in charting market led to an increase in second-hand ship and new-building ship price in long-term equilibrium relationship. In the past, the drybulk shipping market was determined by the volatility of fleet and trade volume. but, in the future, available fleet volume volatility by pandemics, environmental regulations and climate will be the important factors affecting BDI. To response to the IMO carbon emission reduction in 2023, it is expected that ship speed will be slowed down and more ships are expected to be needed to transport the same trade volume. This slowdown is expected to have an impact on drybulk shipping market, such as a increase in freight and second-hand ship and new-building ship price due to a decrease in available fleet volume.

Until now, The Market of aviation parts had led by OEM(Original Equipment Manufacturer) parts because of aviation industry's nature required higher reliability and safety. But recently, The interest about PMA parts in aviation market is increasing continuously with various environmental changes, such as economic stagnation, oil price rise, development of the manufacture technique and newly rising market of Asia-Pacific region. Actually, after 2006, FAA PMA approval parts are increasing at a rate of around 40,000 parts per year and 2.5% of PMA parts penetration, in 2007, in Asia-Pacific market is forecast to enlarge up to 8% in 2017. So, this paper introduces the process requirements of FAA PMA / EASA EPA and the status of PMA market in order to enhance understanding for certification for aviation parts and to review a new PMA market.

The purpose of this study is to analyze how the vertical integration, which is the main characteristic of the domestic digital music market, appears in each period and how these phenomena affect the digital music market. As a result, we could find out that the domestic digital music market is a vertically integrated market centered on ISPs. There were a variety of subjects that led the digital music market from the early digital music in 2000s to the latest streaming market. However, ISP was the only subject that vertically integrated all aspects of content, distribution, and consumption through its subsidiaries and affiliated companies. A variety of combined services, supplementary services, and fare plans provided by using its platform and network have become mainstream services in the domestic digital market and have fixed the current transaction type in domestic market.

This study categorized the viewpoint of cooperation between schools and communities into marketability and publicness, and the viewpoint of school education and lifelong education. The perspective of school education consider to utilize local resources for the growth of students. The lifelong education perspective sees cooperation between schools communities to support the learning of residents. While the marketability perspective pursues individual choices and diversity of opportunities, the publicness perspective focuses on ensuring citizens' right to learn and evenly distributing learning opportunities. From the point of view of school education, it seeks to utilize local resources for the growth and development of students, and in the view point of lifelong education schools are understood to support the learning activities of residents. Cooperation between schools and communities could be presented by categorizing them into private organization-led, educational authorities-led, and provincial authorities-led depending on the subject of the promotion. Recently, local governments and educational governments, schools and communities are developing to a stage where they cooperate to realize the vision of a educational community. For the cooperation between schools and communities the local community, cooperation between local government and educational government and the harmony between publicness and marketability are emerging as tasks.

Since light curing composite resin was introduced in the 1960s, light curing process has been considered as an essential process. Herein, various light sources became available for the process. Quartz-tungsten-halogen (QTH) light curing units (LCUs) dominated the market until the 1990s, before the LED LCUs started replacing them in the 2000s. The LED, developed approximately 50 years ago, came into use in the dentistry field from the late 1990s, and the LED LCUs, with the 2000s. Since then, the LED LCUs have gone through many advancements to its current fourth generation. In accordance to such advancements of the LED light curing unit, the majority of light curing unit used today are LED LCUs. As much as its usage has increased, it is necessary that dental clinicians understand the characteristics of the device. The objective of this review report is to provide the history of the scientific development and describe the characteristics of the LED LCUs.

나노패턴 제작은 차세대 초고밀도 반도체 메모리기술과 바이오칩 등 나노기술의 핵심 분야로, 나노패턴 구조를 나노-바이오 전자소자 및 반도체 산업분야에 적용할 경우 시장 선점 및 막대한 부가가치 창출 등을 통해 국가경쟁력 강화에 크게 기여할 것으로 기대된다. 하지만 대면적 패턴형성이 어려워 뿐만 아니라 $300^{\circ}$ 이상의 열처리 과정에 의한 생산성이 떨어진다. 또한 나노구조가 잘 이루어진 차원, 표면상태, 결정성, 화학적 조성을 갖도록 하는 합성 및 제조상의 어려움 때문이다. 이에 반해 자기정렬 ITO Dot 형성은 상기 기술한 1차원 나노구조형성을 하는 것에 비하여, 나노구조를 제작하기 위하여 공정이 단순하며, 비용 및 생산성 측면에서 유리 할 것으로 생각된다. 이에 본 연구는 E-beam을 이용하여 형성된 ITO 박막에 HCl solution을 이용하여 자기정렬 ITO Dot 형성 후 n-AlGaInP Vertical LED[VLED] 표면에 nano pillar의 두께에 각기 다르게 형성하였으며, 최종적으로 제작된 VLED의 전기적, 광학적 특성을 조사하였다.

In this study, the methodology for measuring the structure of the Korean defense market and the competition status, and the characteristics of the Korean defense industry and the market are examined. To analyze the structure of the Korean defense market and the competition status, the market share, concentration ratio, and the Herfindal-Hirschman index are employed based on the annual sales of major Korean defense companies. On a basis of the result of the analysis, the suggestions for the Korean defense market to escape from the monopolistic market to be a competitive geographical market are presented. To present the suggestions, markets that have a similarity with the dense market are analyzed. The government's support policy, the selection of the companies led by the government, and the cost of the military are suggested for the defense market on a basis of analyzing similar markets. With the suggestions, when the government pursues the policies, the defense market sticking to principles and fairness is created and the efficiency of the companies operation is achieved, by enhancing the structure of the market fundamentally and the development of the policies in the industry's perspective.
