An Empirical Study on the Impact of Tanker Management Self Assessment(TMSA) Operating for Quality Management on the Satisfaction of Internal Customer and Service Performance

Abstract An Empirical Study on the Impact of Tanker Management Self Assessment(TMSA) Operating for Quality Management on the Satisfaction of Internal Customer and Service Performance LEE, In-Ho Department of Shipping Management The Graduate School of Korea Maritime University Shipping is perhaps one of the internationally recognized industries. Also it is one of the world's greatest and the most dangerous industries. It has always been accepted that the best way of improving safety at sea is by developing international regulations that are followed by most shipping nations. In order to sustain and achieve progress in the shipping company, one has to cope with the rapidly changing world of shipping industry. Following a number of very serious accidents that occurred during the 1980s, which were manifestly caused by human errors, with management faults also identified as contributing factors, IMO(International Maritime Organization) adopted the ISM Code(International Safety Management Code) for the Safe Operation of Ships and for Pollution Prevention in 1993. The ISM Code works in a similar way to the ISO 9000, but focuses on assuring the safety management practiced in ship operation. The ISM Code contains many internal and external elements that are comparable to the ISO 9000 standard. For instance, they stress the needs for the purpose of management review that ensures continuing suitability and effectiveness of the organization through reviewing of the corporate policies, objectives and targets. The compliance requirements in document control and recording for the ISM Code are similar to ISO 9000 standards. They also impose strict auditing requirements that monitor the extent to which corporate policy and objectives are being met. In recent years, the quality and safety requirements in the shipping industries have been more stringent than the previous requirements. OCIMF(Oil Company International Maritime Forum) developed TMSA(Tanker Management & Self Assessment) program for the purpose of further improvement of management quality. And oil majors charter-in the vessel for their own cargoes according to the evaluation of the operating company and vessel on the basis of the TMSA program. There are 12 elements and each 12 elements are identified by focusing the ship's seaworthiness. Oil major company recommend to tanker management company to adopt TMSA on their system Along with this theoretical review, this study on the focus of the Korean tanker ship management company which provides management service examined following issues. First, how each of the key factors of TMSA elements affects internal customer satisfaction. Second, each of the key factors of TMSA elements affects service performance. Third, TMSA operating for their tanker management service is valuable to improve service performance as companies's strategy. For the purpose of clarifying these questions, the empirical study was carried out by conceptual modeling and hypothesis testing. The Data were collected from 106 employees among tanker management companies in Busan, and Seoul by the using questionnaire method. Frequency analysis, factor analysis and the structural equation model were used to analyze the data. To verify the reliability and validity of TMSA subordinate factors, Cronbach's α and confirmatory factor analysis were processed. The hypothesis tests were conducted with regression analysis. The results of this study are summarized as follows(1) Ship's safety and environment, management and human resources and technical elements of the key factor of TMSA are crucial on service performance and foster internal customer satisfaction. KPI and BP of TMSA are effective on customers satisfaction and company's service performance. (2) Ship's safety and environment element of the key factor of TMSA is crucial on service performance. This is core service of ship management company according establishment of ISM code and ship management company is focusing their company policy on ship's safety and environment issues. (3) Change and improvement management element of the key factor of TMSA are not crucial for ship management service performance and customer's satisfaction. In this result, the scope of Korean ship management company is technical management. This means to supply ship's stores and spare parts and employ crew members. But a Korean ship management company have an inclination toward conservation for change and improvement management. So company needs to change the way our regard those with change and improvement. 제1장 서 론 1 제1절 연구배경 및 목적 1 제2절 연구방법 및 구성 3 제2장 이론적 고찰 5 제1절 선박관리서비스의 유형과 선박관리업 현황 5 1. 선박관리업의 정의 및 유형 5 2. 선박관리업 현황 16 제2절 선박관리업의 ISM Code 및 QMS의 도입과 그 효과 26 1.

광학 공진기 기반 구조색 및 이중 이미지 저장 기술 연구

학위논문 (박사)-- 서울대학교 대학원 : 전기·컴퓨터공학부, 2016. 8. 이신두.Recently, structural color has attracted tremendous interest owing to its potential as an alternative to colorant pigment. In contrast to conventional coloration where color is primarily determined by the intrinsic optical absorption of chemical pigments, structural colors arise from the resonant interaction of light with optical nanostructures. Accordingly, structural coloration has several unique features, being differentiated from chemical pigmentation. First of all, any materials can be used for coloration giving more flexibility in material choice. Secondly, overall optical efficiency is relatively high owing to small optical absorption. Thirdly, the size of color pixel can be miniaturized into the scale of diffraction limit. Fourthly, color can change in response to external input by employing active materials. Owing to these attributes, structural colors are anticipated as new platform for the development of highly efficient nanoscale color devices as well as novel application areas that are inaccessible with conventional technologies. Toward the realization of structural colors, there have been largely three strategies according to device platformphotonic crystals, plasmonic nanostructures, and optical micro-resonators. Among them, optical micro-resonators have been considered the most promising owing to high optical efficiency, simple fabrication process, and polarization-independent optical properties. For practical applications, however, several technical issues should be addressed. Firstly, low-cost and high-throughput color integration techniques should be developed. Secondly, the color properties such as angle-dependency and color gamut should be improved. Thirdly, new functionalities such as dynamic tunability should be imposed for use in more broad range of applications. In this thesis, we investigate new device architecture and fabrication techniques to resolve above mentioned technical issues and by extension, develop novel applications by making use of these approaches. First, we present simple and powerful fabrication method based on a series of transfer printings of dielectric materials for the large-area integration of different color elements. By using proposed technique, we demonstrate the prototype of LCDs incorporating color filters based on optical micro-resonators. Toward improving optical properties, we investigate the effect of embedding metallic nanostructure as a phase-shifting element inside resonant cavity. Depending on the geometrical structure of metallic nanostructure, the resonant peak shifts to longer or shorter wavelengths. The ultrathin thickness of a phase shifting element allows for the integration of different color elements as well as the extension of color palette within a uniform thickness of resonant cavity. Moreover, we demonstrate a flexible color element showing no color change during being bent by adopting metallic nanoislands that significantly reduce the angle dependency. Lastly, we also demonstrate novel polarization-tunable color elements having a liquid crystal polymer layer for resonant cavity. Color elements that have different directions of optical anisotropy can be easily integrated on a single substrate by using a series of photoalignment processes. This feature allows for recording two different images within the same device area and resolving them by applying different polarizations. The new device architectures and fabrication techniques presented here would pave the way toward the practical implementation of structural colors for a wide range of visual applications ranging from color image storage to advanced display systems.Chapter 1.

Posterior Reversible Encephalopathy Syndrome after Cesarean Section under Spinal Anesthesia

A posterior reversible encephalopathy syndrome (PRES) is characterized as headache, altered mental function, seizure, and visual disturbances resulted from vasogenic edema in the brain. A 29-year-old normotensive parturient developed a postural headache two days after the cesarean section under spinal anesthesia. The headache was initially misdiagnosed as a postdural puncture headache (PDPH). The patient experienced generalized seizures four days after delivery. Her blood pressure increased to 170/100 mmHg with mild proteinuria. She developed homonymous hemianopsia two days after the seizures. MRI revealed high signal intensity areas in the posterior temporal, frontal, occipital and parietal white matter. Presuming a diagnosis of PRES, the patient was treated with magnesium sulfate, sodium valproate, and carbohydrate solutions. She was discharged without headache or neurologic deficit on postoperative day 13. When patients present a headache with focal neurological deficits or visual disturbances, the anesthesiologist must consider the possibility of PRES and aggressively treat based on the clinical presentation.ope

Essential Facility and Foreclosure

본 연구에서는 필수설비에 대한 거래거절행위가 가지고 있는 경쟁배제 효과에 대해 살 펴본다. 시장지배적 지위 남용의 한 유형으로 규제되는 필수설비에 대한 거래거절은 미 국에서 판례법의 일부로 확립되어 집행되고 있고 국내에서도 그 사례가 발견된다. 필수 설비에 대한 거래거절 규제는 통상 수직적 관계를 가진 기업들 간의 거래에 적용이 되 는 것으로 알려졌으나 수평적인 관계를 가진 기업들 간에서도 적용이 되고 있다. 본 연 구에서는 필수설비에 대한 거래거절 규제의 가장 중요한 성립요건은 관련기업들이 수 직적 혹은 수평적인 관계를 가졌는가가 아니라 그들이 생산하는 제품들 간의 補完性 (complementarity) 성립 여부임을 보였다. This paper analyzes the anti-competitive effect of refusal to supply essential facility. Refusal to supply essential facility, which is a form of the abuse of dominance, has been established from a case in the U.S. and is also observed in Korea. Essential facility doctrine has been applied to cases among firms with horizontal relationship as well as vertical relationship. This paper demonstrates that the condition for the application of essential facility doctrine has to do mainly with the existence of complementarity among the products of the firms rather than with whether the firms are vertically or horizontally related.제원연구재

현대 경제이론의 구조와 문제점

반갑습니다. 여기에 낯익은 얼굴들도 있고 낯선 사람들도 있군요. 우선 이 근 교수께서 상당히 프로젝트에 대한 아이디어가 많으신 분이예요. 그래서 새로운 사업토픽을 많이 잡아내시는데 이것도 그런 것들 중에 하나라고 생각하시면 될 것 같아요. 요즘 선생님들끼리 모여서 하는 세미나는 학부에 많은데, 학생들에게 쉽게 접근할 수 있는 시간을 가지면 어떨까 해서 부탁을 하셨는데 감히 제가 그것을 맡게 됐어요. 사실, 저와 함께 얘기를 했던 학생들은 어느 정도 눈치를 챘겠지만, 저는 자기 인식의 위기(identity crisis)라고나 할까요? 제 자신의 정체성에 대해 상당히 헷갈리는 중입니다. 그래서 혼동되어 있는 상태에서 여러분들에게 좀 이야기를 하고, 왜 혼동되어 있는지를 설명을 할까 합니다. 그래서 내가 이런 발표를 준비하고 있다고 했더니 다른 교수 분들이 학생들이 경제학을 하려는데 왜 굳이 경제학이 문제가 있다고 이야기를 하느냐고 하시더군요. 하지만 저는 이게 꼭 나쁜 일이라고 생각하지 않습니다. 뒤에서 이야기하겠지만 결국은 여러분들이 할 일이 많다는 것으로 받아들일 수 있습니다. 뭐 이미 해결해야할 문제도 없는 분야라면 여러분들이 그냥 그 분야에 대해서 이야기할 필요도 없이 이것을 가지고 나가서 이것저것 응용만 하면 될 텐데, 아직 응용만 하기에는 그렇게 좋은 상황이 아닌 거 같아요, 경제학이라는 분야가 그동안 상당히 성과도 좋았는데, 요즘 생각해보면, 그 성과가 과대 포장되었지 않았는가 하는 생각이 듭니다

G.V. Plekhanov and the Theoretical Foundation of Russian Marxism

Plekhanov was not only the father of social democracy in Russia but also a Marxist theoretician of international renown. Yet when the Bolsheviks came to power in October, 1917, Plekhanov found himself not among the victors. This brief essay explains this personal tragedy as a consequence of Plekhanov's acceptance of Marxism as a closed system of dialectical materialism. Plekhanov joined the revolutionary movement initially as a populist of the Bakuninist bent emphasizing the absolute requirement of mass participation in the coming socialist revolution as opposed to the Tkachevian notion of conspiratorial seizure of power. He was converted to Marxism because he saw it as a philosophical system which guaranteed the eventual victory of socialism and recognized the positive role capitalism and the bourgeoisie were to play. Although Plekhanov tried to make due allowance for the role of individual personalities in history and cautioned against excessive reliance on spontaneity of the masses, he was even more wary of any attempt to force the pace of history. Plekhanov recognized that the development of capitalism in Russia followed a pattern somewhat different from what Marx had in mind, but, unlike Lenin, adamantly refused any necessity to adjust the theory to a reality vastly different from that upon which it had originally been founded. In the end, it was his dogmatic insistence upon the narrowly defined orthodoxy and the idealistic hope to fit the Russian reality into the Procrustean bed of revolutionary Marxism that proved to be Plekhanov's undoing
