The importance of playground, which is a central place in the outdoor space scheme for apartment and in children's outdoor activity, is increasing. The stature and availability in playground may be varied according to connection between playground and outdoor space and to characteristics of outdoor space. The purpose of this study is to arrange basic data in guidelines of a planning for supporting children's development and for activating its use in the apartment housing. This study conducted the field survey and questionnaire research after selecting 4-case apartment complexes based on the relevant preceding research. The survey results are as follows. Children were recognizing and preferring the playground as the central space in outdoor play activity. Mothers were preferring outdoor space adjacent to playground. There were the most responses with saying that a mother takes to play with a child. Children responded that the use of playground and the rides are the outdoor activity that they do the most. And, it was surveyed that there is difference in dweller's using playground by apartment complex according to characteristics of a planning for outdoor space. Given being connected with square with segregation of pedestrian and vehicle and with the resting space, the availability in playground was the highest. The availability in playground, which has high connection with diversely outdoor space elements while having good accessibility to the apartment building, was surveyed to be high. Playground had high preference in case of being connected with waterfront and resting space, rather than green zone. Diverse environmental artifacts and decorative fence may become a visually stimulus source that can activate the use of playground.

The Seomoon Bridge, a new planning site, is located in Sangdang-Gu Seomoon-Dong, Chongju and is the oldest bridge built during the rule of Japanese imperialism. As the name implies, Seomoon Bridge is located on the site adjacent to west gate. The Seomoon Bridge is an important bridge as an historical trace of the vanished town of Chongu. However, as new roads and bridges are built, the Seomoon Bridge is losing its functional aspects and has become an area crowed by many street stalls. Closely located newer to Sajic Fountain, the Seomoon Bridge, which has symbolically significant meaning, now faces many problems such as non-practical use of bridge, indifferent management and non-locality, which creates a negative effect on the surrounding cityscape. given this situation, in 2001, 2, Chongju city published an appeal for public subscription of a practical use plan which may design a new, landmark and establish resting spaces for the public. The basic direction of this planning is designed to be place as the symbolic space representing Chongju, and integrated with the surrounding environmental elements such as Moosim-Cheon(stream) and Sajic Fountain, and as a recreational, resting and leisure space of the public. Especially nightscape of the bridge inspires a fresh impact on many people. Because of the widespread influence of developed cities, diverse spaces which already exist or have disappeared may be reclaimed. By establishing appropriate use plans rather than negligence, this project will propose the improved quality of cityscape and show the possibility of bublic´s outdoor living space, and our team will find out the meaning in these approach methods.

Maturity and spawning of the snailfish, Liparis ochotensis was investigated based on samples collected by gill net in the East Sea of Korea from December 2008 to December 2009. The average total length of L. ochotensis was 63.4 cm and 64.1 cm for females and males, respectively. Gonadosomatic index (GSI) began to increase in July, reaching a maximum in November, then began to decrease in December. Monthly changes in the GSI values of L. ochotensis were similar for females and males. Annual reproductive cycle of this species can be divided into five successive stages in females: early growing stage (May), late growing stage (June to July), mature stage (August to September), ripe and spent stage (September to December), and recovery and resting stage (January to April). Males show four successive stages; growing stage (May to July), mature stage (August to September), ripe and spent stage (September to December), and recovery and resting stage (January to April). Relationship between total length (TL) and fecundity (F) was F=$0.00003TL^{4.002}$ ($R^2$ = 0.703), and F increased with TL. Total length at 50% group maturity was estimated to be 55.8 cm. Our findings suggest that the spawning period takes place from September to December, with the main spawning period occurring from October to December.

The purpose of this study was to analyze the usage characteristics and the role of spatial and social psychology of open spaces in urban neighborhoods. The survey for this study was conducted on 318 residents in Gyungsan. For analysis, the frequencies and means were calculated, the chi-square test, t-test, and analysis of variance were performed. Survey results revealed that, first, not only the preferred open space type but also the usage characteristics by gender were different. The tendency for males was to visit open spaces to exercise and to stay for longer than one hour. However, the females visited open spaces to care for their children and meet friends or neighbors. They also visited more often than males but stayed for a shorter time. Second, females tended to consider the open space as a place for rest and leisure. Females valued the social psychology aspects of the open space function. Third, regarding the spacial role of open space in urban neighborhoods, study participants believed that the waterside parks improve the quality of life, but were concerned for the safety of children. Considering the social psychology role of open spaces, study participants regarded the waterside parks as improving emotional health. Particularly, they believed the waterside parks played a greater role in daily life as a place for meeting, resting, and leisure than other open space types such as playground, children's parks, and sport parks.

This landscape design proposal was presented to a design competition for the Culture.Welfare.Administration Complex of Yongin-City which was held by Yongin-City in December, 2001. The site is located at 68-19 Yukbuck-dong, Yongin-City, Kyunggi-do and has an area of 236,449$m^2$. The judging criteria for landscape design set by the Yongin-City could be articulated as follows: an environment friendly design respecting the surrounding environment, a locale as a community center of Yongin-City, a resting place for the welfare of employees and visitors, and finally a place with diverse landscape elements reflecting the individual identity of each facility. This proposal chose the main design concept of this project as‘Nature meets City'. A grove of pine trees fragments the multi building complex, so that‘nature'was brought into the‘city'. A double ground system was introduced to respect the existing topography and to enhance the efficency of the land. This design proposal consists of four segments. Each segment has its own design theme. Outdoor space of this multi-purpose complex was designed with themes of nature, culture, welfare and administration. Space composition with grid and natural looking curvilinear lines was a design motive for this complex. The nature oriented planting design was introduced to respect the existing groves of Mt. Suksung. Specific species were chosen to follow its own spatial character in each space. An environmental sculpture called‘Dream Soaring'was placed in the middle of‘Citizen Plaza'. Its light and feather-looking shape symbolizes the vision of Youngin-City. At night people can watch the diverse color changes on its mirror-like surface.

An Electric Vehicle (EV) is operated with the electric energy of a battery in place of conventional fossil fuels. Thus, a suitable charging infrastructure must be provided to expand the use of electric vehicles. Because the battery of an EV must be charged to operate the EV, expanding the number of EVs will have a significant influence on the power supply and demand. Therefore, to maintain the balance of power supply and demand, it is important to be able to predict the numbers of charging EVs and monitor the events that occur in the distribution system. In this paper, we predict the hourly charging rate of electric vehicles using transformation matrix, which can describe all behaviors such as resting, charging, and driving of the EVs. Simulation with transformation matrix in a specific region provides statistical results using the Monte-Carlo Method.

This research was planned to propose some suggestions on the management of stream water quality in the closed valley areas of the Puk'ansan National Park during July 1998 to June 1999. A closed valley area should designate whole valley area. Stream water quality monitoring should include investigation on cations ($Ca^{2+}$, $Mg^{2+}$, $K^+$, $Na^+$), anions ($Cl^-$, $SO{_4}^{2-}$) and suspended solids. A counterplan for stream water preservation and its practical application should be considered before closing a valley area. Also, the results of stream water quality in the closed valley areas in the National Park should be informed to the public. Discharged water from private areas such as a Buddhist temple, shelter, resting place, shopping center, etc. in the National Park should be checked and cleaned. We need to establish regulations on the utilization of stream side area in the park, and trails near the closed valley should also be included in the areas.
