최근 다국적기업들의 해외진출이 활발해지면서 글로벌 브랜드에 대한 관심이 높아지고 있다. 본 연구는 브랜드 글로벌성(PBG, Perceived Brand Globalness)을 재개념화하고 개념의 다차원성에 대한 타당성을 실증적으로 분석하고자 한다. 더 나아가 글로벌 브랜드성이 브랜드 태도에 미치는 영향을 실증적으로 분석하고자 한다. 이를 위해 중국 소비자들을 대상으로 4개 글로벌 브랜드에 대한 설문조사를 실시하였다. 실증분석 결과, 브랜드 글로벌성은 단일 차원이 아닌 다차원으로 구성된 개념으로 나타났으며, 소비자의 브랜드 평가에 유의미한 영향을 미치는 것으로 나타났다. 이 에 본 연구는 브랜드 글로벌성의 다차원성을 검증함으로써 학문적 및 실무적 관점에서 의미 있는 시사점을 제공할 수 있을 것으로 기대된다.

Due to the existence of uncertainties and the unknown time variant environmental disturbances for ship course nonlinear control system, the ship course adaptive neural network robust course-keeping controller is designed by combining the backstepping technique. The neural networks (NNs) are employed for the compensating of the nonlinear term of the nonlinear ship course-keeping control system. The designed adaptive laws are designed to estimate the weights of NNs and the bounds of unknown environmental disturbances. The first order commander are introduced to solve the problem of repeating differential operations in the traditional backstepping design method, which let the designed controller easier to implement in navigation practice and structure simplicity. Theoretically, it indicates that the proposed controller can track the setting course in arbitrary expected accuracy, while keeping all control signals in the ship course control closed-loop system are uniformly ultimately bounded. Finally, the training ship of Dalian Maritime University is taken for example; simulation results illustrated the effectiveness and the robustness of the proposed controller.

Although China and Vietnam are involved in both territorial and boundary disputes in the South China Sea, at present, managing the territorial dispute over the Spratly Islands is more significant than anything else. Analysis of the dispute based on international law, particularly on the ICJ case law, may help the two sides to manage their dispute in a new perspective and generate political willingness to negotiate the joint development area instead of the sovereignty over the islands. China’s policy that the joint development area around the disputed islands is negotiable is quite a positive signal for peace in the South China Sea and provides a practical basis for new negotiations between China and Vietnam.

This paper introduces a special spheroidizing technology at ultra-high temperature. The conventional cast tungsten carbide (YZ) is melted at high temperature, rapidly cooled and spheroidized on a new ultra-high temperature spheroidizing equipment to prepare various grades WSC powders.

In this paper, the potential ground motion in terms of the peak ground accelerations(PGAs) due to long-distance Sumatra earthquakes is investigated for Singapore, following the probabilistic seismic hazard assessment a, pp.oach. The case investigated differs from a conventional one, in that few attenuation equations for long-distance major earthquakes are readily available. The attenuation relationships developed for other regions of the world are thus reviewed. It is found that the existing attenuation equations, when extrapolated to distant major earthquakes, tend to underestimate the PGAs. By comparing with the PGAs recorded over long distances at stations of the Japanese Meteorological Agency for major earthquakes in Japan, an attenuation equation is chosen for this study. With the chosen attenuation equation, the probability of PGAs exceeding selected levels for various exposure periods of time is then computed. The results show that at Singapore there is a 10% probability in 50 years for the PGA at rock sites to exceed 1.1% g. In view of the results and the associated uncertainties, a base shear coefficient of 1.5% is being recommended as the tentative seismic loading in Singapore. The tentative seismic loading reflects the design value of the notional horizontal load, equal to 1.5% of the characteristic building weigh as specified in the BS code, which usualy governs the design of most buildings in Singapors.

Tannic acid(0.5 ㎎/㎖, 1.0 ㎎/㎖ , 2.0 ㎎/㎖)와 카드뮴(20 ㎎/㎏)을 마우스에 경구투여한 결과는 다음과 같다. 1. Tannic acid와 카드뮴을 투여한 마우스의 증체량과 음수소비량에 변화가 있었으나, 카드뮴투여에 의한 변화는 tannic acid투여에 의하여 감소되었다. 2. 카드뮴투여에 의하여 간장의 상대중량과 뇌 상대중량이 대조군에 비하여 유의한 변화가 있었으며, tannic acid 1.0 ㎎/㎖투여군에서는 간장의 상대중량, 폐장의 상대중량, 흉선의 상대중량도 유의하게 변화하였다(P<0.05). 3. Hemoglobin contents, packed cell volume, platelet count, neutrophill count등의 혈액학적인 변화는 대조군에 비하여 카드뮴투여군에서 유의한 변화가 인정되었다. 그러나, 이러한 유의한 변화가 tannic acid를 동시 투여한 군에서는 나타나지 않았다. 4. 카드뮴을 투여한 군에서는 혈청학적 변화(ALT, AST, BUN와 creatinine)가 있었으나 tannic acid 0.5, 1.0, 2.0 ㎎/㎖을 동시투여한 군에서는 회복되는 경향이 나타났다. 위의 결과로 미루어 카드뮴 투여에 의한 독성이 tannic acid을 2.0 ㎎/㎖/day 이상 4주간 투여하였을 때 경감효과가 나타날 수 있었다. 그러나, 카드뮴과 같은 중금속의 독성에 tannic acid가 어떻게 경감효과를 나타내는지에 관한 작용기전의 연구가 더 필요할 것으로 사료된다.

In order to improve the social service level of museums, digital media and artificial intelligence have become common application technologies in the field of Museum exhibition. The functional orientation of museums is constantly adjusted with the changes of technological development trend, cultural trend and lifestyle in modern society. The development of mobile Internet and intelligent technology has profoundly subverted people’s way of life. Digital exhibition is rising in line with people’s living habits of obtaining information and social communication. However, from the perspective of the relationship between digital exhibition and audience, there are obvious deficiencies in the research field of digital exhibition activities in the field of functional orientation and meaning innovation. Therefore, this paper attempts to explore the function, narrative and meaning of digital exhibition from the perspective of the audience with the concept of “post Museum” and through the analysis of classic cases in the field of digital exhibition. The purpose of this study is to analyze the function and meaning of digital exhibition from the perspective of the audience, clarify the path of the future development of the museum, and explore the narrative structure of exhibition language in the digital context. The research results will provide new theoretical support and design strategies for future museum exhibition design.

The Korean government has introduced and enforced maritime traffic safety assessment to secure traffic safety since 2010. The maritime traffic safety assessment is needed by law to design a new port or modify an existing one. According to Korea Maritime Safety Act, in the assessment the propriety of marine traffic system consists of the safety of channel transit and berthing/unberthing maneuver, safety of mooring, and safety of marine traffic flow. The safety of channel transit and berthing/unberthing maneuver can be evaluated only by ship-handling simulation. The ship-handling simulation is carried out by sea pilots working with the port concerned. The vessel’s proximity measure is an important factor to evaluate traffic safety. The proximity measure is composed of vessel’s closest distance to channel boundary and probability of grounding/collision. What is more, the probability of grounding becomes important. According to central limit theorem, a sample has a normal distribution on condition that its size is more than 30. However, more than 30 simulation runs bring about the increase of assessment period and difficulty of employing sea pilots. Therefore this paper is to find out minimum sample size for evaluating vessel’s proximity. First sample sets of size of 3, 5, 7, 9 etc. are selected randomly on the basis of normal distribution. And then KS test for goodness of fit and t-test for confidence interval are applied to each sample set. Finally this paper decides the minimum sample size. As a result this paper suggests the minimum sample size of 5, that is, the simulation of more than five times.
