The purpose of this study is examining an influence of a corporate on processed marine product's purchase intention with moderating effect of consumers' product evaluation adding processed marine product's evaluations as new variable. The hypothesis of a positive influence of processed marine product's corporate image on processed marine product's purchase intension is partially supported. Specifically, product itself, service, reliability, and communication among the factors of a processed marine product's corporate image significantly affect processed marine product's purchase intension whereas corporate social responsibility does not affect processed marine product's purchase intention. Processed marine product's evaluation also positively affects processed marine product's purchase intention. It implies that there are somewhat differences between influences of various factors of a processed marine product's corporate image on processed marine product's purchase intention but are overall influences of a processed marine product's corporate image on processed marine product's evaluation both directly and indirectly. Nowadays, consumer considers not only good quality of product but also its invisible image and value. Therefore, future studies should consider various ways to investigate a processed marine product's corporate image and processed marine product's product evaluation.

The purpose of this paper is to find out how catches of certain species of marine fish in China influence the marine fisheries of Korea. The results are as follows: 1) While the catches of the main species of marine fish are over 74% in Korea, those of China are under 45%. 2) The main species of marine fish in China(MFC) are hair tails, jack mackerels, anchovies, mackerels, Spanish mackerels, pomfrets, redlip croakers, fie fish, sea breams, sardines, croakers and bigeyed herrings. 3) All the MFC belong to the main species of marine fish in Korea. 4) The fishing grounds of hair tails, jack mackerels, mackerels, Spanish mackerels, pomfrets and croakers in China are similar to those of Korea. 5) Catches of hair tails, jack mackerels, Spanish mackerels, pomfrets, file fish, sea breams and bigeyed herrings in China are many times more than those in Korea. Therefore Korea can't compete with China with such species of marine fish. 6) The price of MFC apart from mackerels and sardines is more competitive than the price of such species in Korea. When the catches of China's marine fish are imported, the species of China's marine fish that will have a great influence on the marine fisheries of Korea are hair tails, jack mackerels, pomfrets and sea breams.

The Korean marine equipment industry is, in significant ways, behind the shipbuilding industry. For example, in terms of the number of orders received, the shipbuilding industry has ranked first in the world since 2003. In contrast, the global competitiveness of Korea's marine equipment industry is still relatively weak. This is important not only for the equipment industry, but because these two industries have many links. The structure of this research was firstly, to identify theoretical issues by looking at the characteristics of the marine equipment companies, marketing recognition, uses of marketing, and financial outcomes. Second, the study developed an analytical framework for empirical examination using configuration of each factor. Third, each factor has been analysed empirically. Forth, this study presents the importance of marketing for marine equipment companies within Korea, as well as in a global market. Finally, the study suggests a new marketing strategy for Korea's marine equipment companies to achieve global competitiveness.

The influence of waves on the dynamic properties of bending moments at the root of blades of tidal stream vertical axis rotors is reported. Blade theory for wind turbine is combined with linear wave theory and used to analyse this influence. Experiments were carried out to validate the simulation and the comparison shows the usefulness of the theory in predicting the bending moments. The mathematical model is then used to study the importance of waves for the fatigue design of the blade-hub connection.

The research was conducted on 238 marine sports participants by clarifying the relationship among self-efficacy, sociality, and organization culture, to eliminate the organizational(home, school, club, workplace, etc.) culture maladjustment phenomenon which is caused by personal stress, the lack of physical activity, and the lack of sociality due to the rapid change of modern society and enhance sociality, adjustment to society and the lack of creativity due to the rigid hierarchy and contribute to organization culture through marine sports among sports which we enjoy with nature. Firstly, according to general self-efficacy, and social characteristics of the organizational culture and the gender differences in higher than women in all sub-variables of the sub-factors of self-efficacy and self-regulation, sociability, organizational culture, sub-culture and develop cultural factors agreed man showed that in the sub-factors of organization culture showed that the development of high culture and hierarchical culture in the age of 20s. Secondly, in terms of the effect of self-efficacy of marine sports participants on sociality, it is found that self-regulation and level of difficulty positively influence on the culture of agreement, the culture of development and the culture of hierarchy. Lastly, in terms of the effect of self-efficacy of marine sports participants on organizational culture, it is shown that self-regulation has positive influence on the culture of agreement, the culture of development and the culture of hierarchy.

Investigating ship motion under real conditions is vital for evaluating the seakeeping performance, particularly in the design process stage. This study examined the influence of the principal particulars of a trawler on its seakeeping performance. The wave conditions in the Bering Sea are investigated using available data. The length-to-beam (L/B) and beam-to-draft (B/T) ratios of the ship are changed by 10% for the numerical simulation. The response amplitude operator (RAO) motion, root mean square (RMS) value and sensitivity analysis are calculated to evaluate the influence of the trawler dimensions on ship motions. The peak RAO motion affected the ship motions noticeably because of the resonance at the natural frequency. The L/B and B/T ratios are important geometric parameters of a ship that significantly influence its RMS motion, particularly in the case of roll and pitch. The change in the B/T ratio has a good seakeeping performance based on a comparison of the roll and pitch with the seakeeping criteria. The present results provide insights into the seakeeping performance of ships due to the influence of the principal dimensions in the design stage.

Pelagic larval dispersal habits influence the population genetic structure of marine mollusk organisms via gene flow. The genetic information of the clam Gomphina aequilatera (short larval stage, 10 days) which is ecologically and economically important in the China coast is unknown. To determine the influence of planktonic larval duration on the genetic structure of G. aequilatera. Mitochondrial markers, cytochrome oxidase subunit i (COI) and 12S ribosomal RNA (12S rRNA), were used to investigate the population structure of wild G. aequilatera specimens from four China Sea coastal locations (Zhoushan, Nanji Island, Zhangpu and Beihai). Partial COI (685 bp) and 12S rRNA (350 bp) sequences were determined. High level and significant $F_{ST}$ values were obtained among the different localities, based on either COI ($F_{ST}=0.100-0.444$, P<0.05) or 12S rRNA ($F_{ST}=0.193-0.742$, P<0.05), indicating a high degree of genetic differentiation among the populations. The pairwise $N_m$ between Beihai and Zhoushan for COI was 0.626 and the other four pairwise $N_m$ values were >1, indicating extensive gene flow among them. The 12S rRNA showed the same pattern. AMOVA test results for COI and 12S rRNA indicated major genetic variation within the populations: 77.96% within and 22.04% among the populations for COI, 55.73% within and 44.27% among the populations for 12S rRNA. A median-joining network suggested obvious genetic differentiation between the Zhoushan and Beihai populations. This study revealed the extant population genetic structure of G. aequilatera and showed a strong population structure in a species with a short planktonic larval stage.
