The east Sea circulation is numerically modeled with refined grid resolution elaborated open boundary condition, and by directly imposing the measured surface temperature and salinity typical the east Korean Warm current are clearer than those in previous works. among others, The Ulleung warm Water and the Intermediate Water of minimum salinity are nicely reproduced. The latter is formed in the northern/northwestern coastal region in winter and is advocated southward by strong under-current. the former is associated with a locally generated anti-cyclonic gyres. The model indicates strong seasonal variation of Nearshore Current along the Japanese coast from wintertime barotropic to summertime baroclinic structures. the associated strong reversed under-cur-rent in summer is not well understood. Global circulation pattern is characterized by two regions of cyclonic and anti-cyclonic gyres in the north and south, respectively. The presence of these gyres indicates importance of local dynamics in East Sea circulation. This model, however, does not completely resolve the problem of overshooting of the East Korean Warm current.

Simulation of local external forcing and its response in the rotation table experiment has been investigated. Spatially-uniform external forcings have been applied in many experimental studies, however, based on the fact that the north-south distribution of the wind-stress curl and the existence of local maximum of the sea surface heat loss in the northern part of the East Sea, new method of combined effects of local forcings has been employed in separate experiments. Carefully designed local source or sink at the bottom of the cylindrical container can produce horizontal pressure gradient within the Ekman layer, and consequently the interior also attains the same pressure gradient that produces geostrophic interior circulation. In order to keep free surface during the local-surface cooling, a side-wall cooling method is suggested. For the various type of local forcing including the effects local cooling and the periodic change of local wind-stress curl, western-boundary flow in terms of its strength, position of separation from the boundary have been observed.

Ian Watt, author of The Rise of the Novel, maintained that the novel originated in modern England, came from prose discourses such as the news, political essays and journalistic writing which propagated the Enlightenment, and the novels represent formal realism. The main point of this paper is to examine Watt's theory of the rise of the novel on the basis of the criticism of antinomy of the Enlightenment and "the public sphere" in Habermas' terms. At first, I will criticize formal realism, which is not a new literary species, but a formally renovated realistic form that represented capitalism and protestantism. And, then, I will show that formal realism is a kind of antinomy because it turned away from the voices and reality of the low-class and women though the novel concentrated on common people, not the aristocrats. Secondly, I will inquire into the antinomy of the Enlightenment in the aspects of reason, freedom, individualism and women. In my view, as soon as the high-middle class acquired their political rights, these values were no more encouraged and the result revealed antinomy of the Enlightenment more explicitly. Thirdly, I'd argue that "the public sphere" had positive meanings to everyone when the bourgeosie were fighting against the Absolutism and the aristocracy. I'll also insist that the high-middle class and the intellectuals were in "the public sphere" in which Habermas argues that rationality and equality were thought to have been realized, while the low-middle class and most women were de-enlightened and disciplined by reading the novel privately. In conclusion, formal realism is not the rise of the novel, but the opening of the novel peculiar to bourgeosie parliamentarism from the middle-eighteenth century to the middle-twentieth century.

In view of the numerous discussions on global environmental issues, policies have been implemented to limit emissions in the field of marine transport, which accounts for a major part of international trade. In this study, a ship's emissions were calculated by applying the engine load factor to determine the total quantity of emissions based on the ship's speed reduction. For ships entering and leaving the Busan North Port from 1 January to 31 December 2017, emissions were calculated and analyzed based on the ship's type and its speed in the reduced speed zone (RSZ), which was set to 20 nautical miles. The comparison of the total amount of emissions under all situations, such as cruising, maneuvering, and hotelling modes revealed that the vessels that generated the most emissions were container ships at 76.1 %, general cargo ships at 7.2 %, and passenger ships at 6.8 %. In the cruising and maneuvering modes, general cargo ships discharged a lesser amount of emission in comparison with passenger ships; however, in the hotelling mode, the general cargo ships discharged a larger amount of emission than passenger ships. The total emissions of nitrogen oxides (NOx), sulphur oxides (SOx), particulate matter (PM), and volatile organic compounds (VOC), were 49.4 %, 45 %, 4 %, and 1.6 %, respectively. Furthermore, the amounts of emission were compared when ships navigated at their average service speed, 12, 10, and 8 knots in the RSZ, respectively. At 12 knots, the reduction in emissions was more than that of the ships navigating at their average service speed by 39 % in NOx, 40 % in VOC, 42 % in PM, and 38 % in Sox. At 10 knots, the emission reductions were 52 %, 54 %, 56 %, and 50 % in NOx, VOC, PM, and Sox, respectively. At 8 knots, the emission reductions were 62 %, 64 %, 67 %, and 59 % in NOx, VOC, PM, and Sox, respectively. As a result, the emissions were ef ectively reduced when there was a reduction in the ship's speed. Therefore, it is necessary to consider limiting the speed of ships entering and leaving the port to decrease the total quantity of emissions.

When we say the core thought of the Analects of Confucius, we normally come up with 'Ren(仁)'. However, in the first phrase of Chapter One("學而") of the Analects, there is no mention about 'Humanity'. Then, why the editor of the Analects of Confucius had put the First Chapter at the opening of book? This paper aims to describe the fact that the First Chapter One of the Analects of Confucius implies the core thought of Kongzi(孔子). In the First Chapter One, the vocabularies, such as 'Pleasure'(說), 'Delight'(樂), and 'Confucian Gentlemen'(君子) are central to the phrasal structure. 'Pleasure'(說) is the phase to cultivate himself, or the phase to equip with a qualification in order 'to establish a righteous relation'. And 'Delight'(樂) is the stage to establish relationships with colleagues who share same value and ambition with himself. 'Confucian Gentlemen'(君子) is the stage to 'establish righteous relationships' with all people in the world, and it denotes an ideal human image presented by Kongzi(孔子). The core concepts of the First Chapter One are connected to the core thoughts of the Analects of Confucius, to wit, 'Ren'(仁), 'Shu'(恕), and 'Xiujizhiren'(修己治人). If 'Ren'(仁) and 'Shu'(恕) refer to specifically 'establishment of righteous relationship', then 'Pleasure'(說) is the stage to obtain qualification in order to 'establish righteous relationship', and 'Delight'(樂) is the stage to 'establish relationships' with brothers and colleagues, and 'Confucian Gentlemen'(君子) means a person who can build up 'righteous relationships' with all the people of the world. Regarding the Confucianism in 'Character building and guiding other souls' Confucius presents three phases, viz. 'Cultivation of himself in reverential carefulness'(修己以敬) ${\rightarrow}$ 'Cultivation of himself so as to give rest to others'(修己以安人) ${\rightarrow}$ 'Cultivation of himself so as to give rest to all the people'(修己以安百姓), and the se get through 'Pleasure'(說) ${\rightarrow}$ 'Delight'(樂) ${\rightarrow}$ 'Confucian Gentlemen'(君子) in the First Chapter One of the Analects of Kongzi(孔子). The human image, named 'Confucian Gentlemen'(君子) presented in the Chapter One is equated with the human who practices 'morality'(修養) that attained by means of 'cultivation'(實踐) through 'establishment of relationship'.

The core thought of Confucius("論語") is 'Ren(仁)'. Then, how ought we to interpret this 'Ren(仁)'? In this study, the researcher has interpreted 'Ren(仁)' from the perspective of Xiujizhiren(修己治人), which is the doctrine of Confucianism and its ideal. At first, the researcher closely reviewed Ren(仁) on the viewpoint of Xiuyang (修養). Ren(仁) is the most fundamental virtue that enables general populace to equip with their qualification as a human being. Specifically, to live like a human being, Ren(仁) is a must. That is to say, it will suffice if we only can expose well what was already cherished inside us, rather than exerting efforts to attain Ren(仁), in some contexts, that must achieve in order to live like a human being. The reason that we exert our efforts for self-cultivation is to bring this Ren(仁), which is foundation of human life, before the public. Even in relationship-building, Ren(仁) is necessary. Human being is not an existence that can live alone, but at all times, humans are required to build a relationship with others. To make this relationship-building lead into right direction, we need to think of that the standpoint of oneself and the other are identical. That is, when I myself and the other person are in the most optimal situation, then a right relationship-building can take place. This most optimal status is Ren(仁). The ideal of Confucianism is to establish a society where all people can enjoy their comfortable life. To accomplish such a society, each individual and society ought to be benevolent and to cherish humanity at the first place. That is to say, people should attain Ren(仁) from both aspects of Xiuji(修己) and Zhiren (治人). If Ren(仁) has not been attained from any of either side, then it is hard to say that the ideal of Confucianism is completely realized. However, Zhiren(治人) must be backed up by Xiuji(修己). For this reason, Kongzi(孔子) presented three steps in connection with this cultivation process, to wit, 'Cultivation of himself in reverential carefulness'(修己以敬) ${\rightarrow}$ 'Cultivation of himself so as to give rest to others'(修己以安人) ${\rightarrow}$ 'Cultivation of himself so as to give rest to all the people'(修己以安百姓). It is noticeable that Xiuji(修己) is included in all three phases. The society that Kongzi(孔子) longed for is still valid in this modern world. Therefore, Ren(仁) which was edified by Kongzi(孔子) is necessary for today's society. If we don't interpret Ren(仁) as with a fixed term lying stagnant in one place, then its definition shall be interpreted newly so as to suit the times and the situation of civil society, thus this Ren(仁) shall be the foundation for building a desirable society for humans.

It includes the considerable concentration and dangerousness as the peculiar work of a pilot and dock-master to berthing/deberthing the big object as for the ship within the port or the ship yard. A tug utilization is getting increased in this berthing/deberthing work and the own ship is affected a lot by external force due to moving with low advance speed. In this study, we constructed the 2 dimension virtual system which can conduct the berthing/deberthing manoeuvring work by using mainly tugs in a external force, particularly strong wind. Also, propose objective standard that could estimate the degree of manoeuvring difficulty, and conducted simulation experiment for this. we analyzed correlations between the subjective estimation which is described numerically the decreased dangerousness and the objective index which is related to the main parameter regarding manoeuvring by using this simulator from the result of conducting simulation experiment. And then we discussed the estimation technique of manoeuvring difficulty.
