With an increase in urban crimes in various forms, this study is intended to analyze the effectiveness of the service design that presented a new model resolving crime risks through differentiated thinking paradigm and problem approaches. The empirical case addressed in this study is 'the project to create resident-driven safe community in Duryu-dong, Dalseo-gu, Deagu though service design'. This project is evaluated as having prepared a prevention-oriented local safety system through a preemptive and resident-centered process. The project was promoted as a 'natural monitoring capacity building program' for residents to prevent local crimes, a 'social role expansion program' for local safety, and 'crime prevention environment design', which provides comprehensive solutions for residents' safety. Here, designers act as exerts in designing a task-based platform that can be driven by residents rather than a visual environment improver, and reorganizing the local ecosystem by expanding the opportunities for residents to interact. This case identifies the role of service design as binding the solidarity of local residents beyond the improvement of the crime environment and giving them the potential capacity to maintain a safe living space in relation to a safety issues of community.

Green Growth was declared as a national development agenda in 2008. There are many contributing concepts and factors in the process of molding the agenda, such as climate change, sustainable development, globalization, the so-called 747 campaign pledges by President Lee in 2007, and the hunger for economic growth in Asia and the Pacific. Green Growth is rather growth-oriented and pays less attention to environmental conservation and social justice. Green Development would fit better as the name of the agenda, dealing with the weaknesses of Green Growth. Climate change itself is a testing ground for geographic knowledges, whose demand is growing rapidly. The contemporary issue increasingly bears complexity that Earth System Science and Sustainability Science have emerged as a research and applications program. Geography is widely recognized as a portal to these programs, where inter- and trans-disciplinary studies are required. Regional potentials should be evaluated from a holistic view so that proper development goals are chosen. Different development trajectory should be taken, depending on the amount of potential a region bears. Material loop should be closed for environmentally sound regions. Green way of life is essential for low carbon society. In the circumstances of climate change in Korean Peninsula and needing of energy efficiency, geographic insight or imagination is urgent for Green Development.

An experiment was conducted to evaluate the efficacy of continuous lateral shoot pinching and gradual adjustment of drip irrigation lines in improving plant health as well as fruit yield and quality in white-spined cucumber grown in the greenhouse. Grafted white-spined cucumber seedlings were established at a density of 18,000 plants per ha in a greenhouse. Main stems were pinched at 21st node. Each of the lateral shoots was pinched at the 3rd node and 2-3 fruits per lateral shoot were harvested. Drip irrigation lines were gradually adjusted to provide water to the area of maximum root concentration. Plants grown with these combined treatments produced $55\%$ more lateral shoots and 38% more marketable yield, as compared to the control.

With the increasing use of mobile phones, mobile game is emerging as an entertainment for move. Furthermore, smart phone is widely spread, so mobile game market is rapidly growing. According to "Republic of Korea 2010 Games White Paper" mobile game market is growing annual average 10% or more, and is expected to reach $ 9.8 billion in 2011. It is almost doubled compared to 2007. It became possible to realize complicated high-capacity game with mobile phone developed to smart phone. And at the same time, mobile game is associated with Social Network Services (SNS) and is worldwide growing as a part of 'mobile life'. Apple launched an application open market, App Store, in 2008, and mobile game industry welcomed an innovative turning point. Global smart phone application market (App Store) is opened, so Gameday is able to launch mobile games easily to the global market getting out of the domestic market. In addition, Apple App Store has the structure of sharing their revenue with the developer with 7 to 3 which is more favorable terms for the developer compared to supply mobile contents to the mobile carrier who monopolized the market in the past. The largest proportion of the current App Store application is game, and Gameday has the opportunity to make a significant leap forward by keeping pace with the new environment changes.

The residence time measures the time spent by a water parcel or a pollutant in a given water body. So residence time of water is widely used as an indicator of how a substance will remain in an estuary and it is used to enable comparisons among different water bodies. To estimate residence time of particulate matters from land and aquaculture, EFDC that includes particle tracking model was applied to the Geoje Bay. Modelled average residence time was about 65 days in the inner part. It meant it takes about 2 months for substance from land and aquaculture to be transported to the outside of Geoje Bay. The results indicated that residence time varied spatially throughout Geoje Bay depending on tidal flushing and, in general conditions, tidal flushing exerts the greatest influence to the flushing of Geoje Bay. This reveals relationships between residence times of particulate matters and physical properties of the bay and Geoje Bay is vulnerable to water quality problem.

The Manseongri Coast meets the sea on the southeast and is composed of coarse sediment as a mesotidal beach. The waves that strike the beach are stronger than the tides or tidal currents as external forces of beach deformation. Storm waves frequently reach significant wave heights of 2-3m and hit in spring and summer, leaving the sea calm during fall and winter. Incident waves reach remarkable heights that correspond with observed shoreline changes. The shoreline erodes in spring and summer due to these strong waves but recovers in fall and winter as a result of the more moderate waves. On the basis of these observed results, a numerical calibration for experiments on shoreline change was established. Results revealed that according to hindcast data, calculated shoreline changes agreed with the observed shoreline, with a minimum RMS error of 1.26m with calibration parameters $C_1=0.2$ and $C_2=1C_1$. Using these calibration parameters, long-term shoreline change was predicted after the construction of submerged breakwaters and jetties, etc. The numerical model showed that the shoreline would move forward by 5-15m behind the submerged breakwaters and recede by 5-15m north of the structure.

According to the related reports, about 60 percents of ship collisions have resulted from operating mistake caused by human factor. Specially, the report said that negligence of observation caused 66.8 percents of the accidents due to a human factor. Hence automatic detection and tracking of an object from an IR images are crucial for safety navigation because it can relieve officer's burden and remedies imperfections of human visual system. In this paper, we present a method to detect an object such as ship, rock and buoy from a sea IR image. Most edge directions of the sea image are horizontal and most vertical edges come out from the object areas. The presented method uses them as a characteristic for the object detection. Vertical edges are extracted from the input image and isolated edges are eliminated. Then morphological closing operation is performed on the vertical edges. This caused vertical edges that actually compose an object be connected and become an object candidate region. Next, reference object regions are extracted using horizontal edges, which appear on the boundaries between surface of the sea and the objects. Finally, object regions are acquired by sequentially integrating reference region and object candidate regions.
