최근 기후변화와 도시화로 인한 수재해 문제가 증가하고 있으며, 이에 대응방안인 저영향개발(Low-Impact Development, LID) 기법에 관한 연구가 확대되고 있다. LID 기법은 도시 내의 우수유출수를 저감시켜 다양한 수재해 문제를 친환경적으로 제어하고, 도시 개발 이전의 물순환 체계로 회복시키는 기술이다. 하지만 LID 기법에 관한 정량적 데이터가 부족한 실정이다. 따라서 본 연구에서는 저류형 LID 기술인 식생화분(Planter Box)의 Curve Number (CN)값을 산정하여, 물순환(침투, 유출, 월류수) 분석을 실시하였다. Planter Box의 물순환 분석에 관한 강우강도 시나리오(60.4 mm/hr, 83.1 mm/hr, 97.4 mm/hr, 108.2 mm/hr)는 부산시 확률강우강도표(2010)를 이용하여 선정하였다. 실험 결과는 건물화분3(BPB-3)과 거리화분3(SPB-3)에서 우수저류율이 각각 43.5%~52.9%, 33.4%~39.0%로 나타났다. 또한 BPB-3에서 CN값은 평균 83이 산출되었고, Horton 침투능 곡선식 적용에 따른 우수유출효과는 17%~96%로 나타났다.

This study is about apartment greening to improve urban environment. To achieve this, questionnaires concerning the planter preferences were distributed. To improve perpendicular greening methods for apartments, MOCT (The Ministry of Construction and Transportation) reformed the law to obligate constructors to make apartment planters in June, 2000. But apartment residents take negative attitudes to making green space. It is difficult to manage the planters as well, so it is necessary that the point at making green spaces at apartments be scrutinized through questionnaires and an active method for making and managing the planter be made. The results show that apartment residents are reluctant to pay the expenses for planting and managing planters and have negative attitudes about plant purchases. If planting and managing of simplified planters are continually entrusted to residents, even vertical landscapes will be affected by illegal diversion and negligence as a result. Therefore, support from governments and local administrations are needed and legal obligation should be imposed on construction companies to install irrigation facilities.

Nowadays, stormwaters have been affected by urbanization and climate change. These transition can cause many problems for hydrologic cycle by increasing runoff volume like flood and low water quality. As with other metropolises and peninsulas, Busan has involved with these problems too. Therefore, it is really vital to do some arrangements to solve them by low impact development (LID) technology. In fact, LID has been introduced to reduce runoff by applying some techniques such as green infrastructure (GI). In order to deal with the aforementioned issues in Busan, this study attempts to design and construct a hybrid green roof-planter box system at Pusan National University GI/LID Facility based on local weather. For this purpose, we used experiment and modeling method on some planter boxes and optimized them by trial and error method.

This study is to improve plan for the law and regulation systems on the perpendicular greening with containers to improve urban environment. The supports backed by laws and regulations are imperative for the activation of building greening. Although some local administrations in Korea try to lead perpendicular greening on building by means of Green Building certification system and so on, greening policies and managements are not pushed forward with consistency. Therefore building greening should be admitted to be a substitute green tract of land. The positive construction and management of greenzone should be accomplished as well. Devices, so to speak, which put greening under an obligation or authorize it as legal landscape area should be made rather than recommendations to make greenzone through current incentive systems. Positive perpendicular greening on building can be achieved by supplementing the law and regulation and incentive system about simplified planter. If planting and managing of simplified planter are continually entrusted to residents, even vertical landscapes will be affected by illegal diversion and negligence in result. Therefore, supports from governments and local administrations are needed.

The garlic, along with the red pepper, is one of the major seasoning vegetables in Korea. Garlic clove planting is one of the most laborious operations. Labor cost is the main source of high production cost of the garlic. Because of the geometrical uniqueness and irregularity of garlic cloves, mechanization of garlic clove planting is very difficult. To overcome price competition against the imported garlic, however, there has been a need of development of a clove metering device and a planting device for the garlic clove planter. Computer simulation, laboratory tests and field tests were conducted to develop a garlic clove planter. This research was conducted to drop garlic cloves into a soil holes through a drum bucket metering system and a rotary type planting system. Followings are the major achievements from this study. 1. The metering device consisted of a drum, a guide, a bucket and a bucket cover. Opening positions of the metering hopper were evaluated at different positions and trajectories of planting hoppers. The simulation showed that the optimum positions of hopper was -15${\sim}$0 mm in the x direction. 2. When the planter was tested under different soil textures and water contents, the best performances were obtained in a upland field with 29.1% water content and a paddy field with 18.3% water content where single clove metering and missing rate were 88.4% and 1.3%, and 90.7% and 2.0%, respectively.
