Globalization of production, changing technology in ocean shipping sector, shifting bargaining power from port service provider to port users, changing distribution patterns of the containerization and new implementation for the environment and safety concerns introduced new ways of administration in port sector. In these days, port industries cannot survive alone. Port operation and management has to be proactive to cooperate and integrate with other port operators or other industries. In the 21st century, cooperation in maritime sector is more common than that in the past with several different reasons in a mixture of forms of cooperation. Cooperation among port authorities, port operators, shipping line, inland transport service providers and/or related organizations themselves becomes to exist to overcome the challenges and development of the global transport chain. This paper investigates the concept of port cooperation and the case analysis of the cooperation in the port industry.

Background: The use of radiation and radioisotopes in Korea has been increasing each year, and its impact on economy and industry is expected to be increasing progressively following the development of industrial technology and the expansion of their usage. To establish and supporting policies for industries using radiation and radioisotopes, it is necessary to check the status of related industries accurately, as well as to gather data required to establish plans for industrial development by studying both revenues and economic scale (contributing to revenue). Materials and Methods: To analyze the status of utilization, surveys were carried out on 6,621 organizations engaged in nuclear operations handling radiation and radioisotopes pursuant to the Nuclear Safety Act as of end 2014, on 33,471 medical institutions using radiation generators for medical and diagnostic purposes pursuant to the Medical Service Act, and on 2,218 organizations using radiation generators for animal diagnostics pursuant to the Veterinary License Act. Results and discussion: The overall status of the domestic radiation market including the number of user organizations, that of employees, and the size of distributions (imports, productions, and exports) with which the scale of domestic radiation market can be judged showed a growth trend compared to the previous year, though the number of employees for radiation operation in industrial sector, research sector, education sector, military sector, and power plants (nuclear power plants) and the size of imports was reduced somewhat. Conclusion: It is expected that data acquired through periodic surveys on the status of utilization would be utilized practically in establishing governmental policies related to the promotion of usage of radiation and radioisotopes, and also be utilized widely in cultivating and developing the industry efficiently to invigorate the related industries.

현재 전력난에 의해 에너지 절감이라는 말은 가정 및 산업 현장 곳곳에서 들을 수 있다. 에너지 절감 대책 중 하나가 몇 년전 정부에서 발표한 백열등 수입 및 유통금지가 있다. 그 효과로 LED 산업이 각광 받게 되었다. 다양한 LED 산업 및 기술에서도 신뢰성 및 성능 분야는 항상 진화하고 많은 기업들이 집중하고 있다. LED에서 중요한 요소인 방열성능을 개선시키기 위해 많은 연구를 행하고 있다. 그리고 광원 개발분야에서도, 반도체 광원의 LED PKG의 다량 실장으로 고출력을 행하는 것 보다는 기판위에 Blue Chip을 실장하여 제작하는 고출력 광원의 기술로 집중되고 있다. 이 논문에서는 고출력 광원인 COB(Chip On Board) LED의 방열성능 개선을 다루었다. 기판의 구조 변형으로 방열특성 개선 대안을 제시하였다. Via hole과 Cavity를 이용한 구조를 제안하였다. 그에 대한 해석 방법으로는, 구조적인 해석과 수치적인 해석을 활용하였다. 그 결과로는 약 13~40%의 방열성능 개선을 나타내었다.

Ethics suggest that all persons are by nature moral, as it would not be possible for humans to exist collectively or even individually without an innate ethical sense. In order for the public sector to thrive in business, the board of directors needs to be guided by ethics and take into account the abiding interests of humanity and public good. It is argued in this paper that the abuse of power in the public sector has often been associated with unethical leadership and conducts which undermines the ubuntu notion. The irregularities which often arise in the awarding of tenders in the state-owned companies are some of the challenges that are prone to the public sector. In order to address these challenges and promote a flourishing democracy it is argued that ethical leadership as envisaged in the King III Report needs to be adhered to by the boards of directors. This paper concludes that the direction and control of ethics in any organisation is vital especially where the line between corporate governance and ethical leadership has become blurred.

This paper is motivated by the lack of studies in the technical literature concerning to the influence of carbon nanotubes (CNTs) waviness and aspect ratio on the vibrational behavior of functionally graded nanocomposite annular sector plates resting on two-parameter elastic foundations. The carbon nanotube-reinforced (CNTR) plate has smooth variation of CNT fraction based on the power-law distribution in the thickness direction, and the material properties are also estimated by the extended rule of mixture. In this study, the classical theory concerning the mechanical efficiency of a matrix embedding finite length fibers has been modified by introducing the tube-to-tube random contact, which explicitly accounts for the progressive reduction of the tubes' effective aspect ratio as the filler content increases. Parametric studies are carried out to highlight the influence of CNTs volume fraction, waviness and aspect ratio, boundary conditions and elastic foundation on vibrational behavior of FG-CNT thick sectorial plates. The study is carried out based on three-dimensional theory of elasticity and in contrary to two-dimensional theories, such as classical, the first- and the higher-order shear deformation plate theories, this approach does not neglect transverse normal deformations. The annular sector plate is assumed to be simply supported in the radial edges while any arbitrary boundary conditions are applied to the other two circular edges including simply supported, clamped and free. For an overall comprehension on 3-D vibration of annular sector plates, some mode shape contour plots are reported in this research work.
