This study aims to evaluate urban parks in terms of public service and to find ways to elevate user satisfaction for the creation and usage of an urban park, on the assumption that an urban park is a sort of urban public service. To achieve this, the study relied on two methods: the descriptive method of researching publications and related scholastic writings, and the empirical study method including a survey and interviews with respondents. As a result, "Conviction for a local government" was the highest item and "benefit of urban parks", "physical environment", and "safety" were of lower orders of evaluation. On the contrary, "park information" and "reflecting of park users' opinion" were the lowest item. This means although the local government has enough ability to provide and manage physical park facilities, the government passes secondary service over lightly, in terms of public service. Correlation and regression analysis showed all positively correlated factors: “Y = -0.465 + 0.164 X1 + 0.176 X2 + 0.197 X3 + 0.169 X4 + 0.186 X5 + 0.148 X6 + 0.112 X7” (Y = park service satisfaction, X1 = credibility, X2 = originality, X3 = accessibility, X4 = representative, X5 = physical settings, X6 = safety, X7 = consensus).Urban parks must be essential public facilities in urban city. Therefore, for maximizing park benefits, more careful consideration will be made in terms of the public service of urban park.

This study aims to develop the information service system of integrated seakeeping performance for seagoing vessels. It has been successful in developing the intended system which has made possible to provide the following functions and capabilities: ⦁ immediate computation of the dynamic motions of a ship against the present and future weather conditions; ⦁ evaluation of the integrated seakeeping performance of a ship on a real time basis and providing the navigators with the seakeeping informations on the spot enabling them to take the most appropriate countermeasures; and ⦁ supporting the navigators in the selection of a safe sailing route by providing the integrateseakeeping performance.
