Recently, the number of design for open-spaces at waterfront, such as open-air restaurant and cafeteria, has been increasing to provide openness and natural environment of waterfront. However, when planning open-air restaurant and cafeteria, it is essential to investigate the climate characteristic of waterfront, especially wind environment, since the waterfront has a special quality of climate like low-temperature and strong wind which differs from downtown or inland. In this study, wind environments of Haeundae, Suyoungman, and Gwanganli, the famous waterfronts in Busan, were investigated for design of open-air restaurants and open cafeterias. The main results were as follows. 1) the waterfront area of Haeundae, Suyoungman, and Gwanganli is suitable for open-air restaurant and open cafeterias; and 2) the appropriate period for open space in this area is from the end of March to November.

Seasonal and regional occurrence of oriental beetle, Blitopertha (=Exomala) orientalis was investigated using pheromone traps and soil sampling at three golf clubs in Busan, Gunpo, and Gimpo from 2004 to 2007. Adults of Blitopertha orientalis were found from early June to late August, but peak times were different depending on the location and year. Peak day of adult occurrence of B. orientalis was 25 June,2006 and 22 June 2007 in Busan, but 30 June,2006 and 29 June,2007 in Gunpo. Mean numbers of B. orientalis adults attracted to pheromone trap varied with locations. Larval development was faster in Busan than in Gunpo. The 2nd instars of B. orientalis was found on 27 August, 2004 in Gunpo whereas 3rd instars were found in Busan in the same period. In Busan, overwintered 3rd instars pupated from early May to mid-June and emerged from early June. Eggs laid at this time were hatched from late June Most 3rd instars were found at middle August and started to overwinter. The peak time of mating was 20:00 to 22:00 hour of the day.

Donghaean Byeolsingut itself reflects the ideals and dreams of seaside life. Imagination and interest in water are fully reflected in Donghaean Byeolsingut as a living in a seaside town. For the beach people, water is the foundation of life and the object of fear. It is the water of life and the water of death. It projects the whole process of life into the imagination created by the world encompassed by the sea. The beach's imagination is an existential insight into the whole process of life and a reflection of existential agony. At Poongeoje, the villagers hope for a specific blessing from God. People are free only when God's retribution comes down. The villagers feel free because of the virtue of the shaman's blessing. Individual trauma is experienced to a certain extent by gaining mental freedom. It can be said that the state of aesthetic pleasure experienced by creating an art work by itself and the nature of aesthetic pleasure experienced through Pungeoje and Byeolsingut are not different. The prototype of Poongeoje is a free spirit, and a religious aesthetic to strengthen the free spirit is the core of the aesthetic.

Recently, the development of various culture-independent identification techniques for environmental microbes has greatly enhanced our knowledge of microbial diversity. In particular, denaturing gradient gel electrophoresis (DGGE) of 16S rDNA fragments, generated using the polymerase chain reaction (PCR) is frequently used to examine the diversity of environmental bacterial populations. This method consists of direct extraction of the environmental DNA, amplification of the 200-600 bp 16S rDNA fragments with universal primers, and separation of the fragments according to their melting point on a denaturing gradient gel. In this study, we investigated the seaside microbial community in coastal areas of Busan, Korea, using culture-independent techniques. First, marine genomic DNA was extracted from seawater samples collected at Songjeong, Gwangahn, and Songdo Beaches. Then, PCR was used to amplify the bacterial 16S rDNA using universal primers, and DGGE was used to separate the amplified 500 bp 16S rDNA fragments. Finally, the tested 16S rDNA genes were further analyzed by sequencing. Based on these experiments, we found that DGGE analysis clearly showed variation among the regional groups. It can be used to monitor rapid changes in the bacterial diversity of various environments. In addition, the sequence analysis indicated the existence of many unculturable bacteria, in addition to Arcobacter, Pseudoaltermonas, and Vibrio species.

The RC buildings which are constructed on the seaside are followed by KBC(2016) to achieve the minimization of durability damage. To control the corrosion of the reinforcing steel bar by salt attack, W/C should be under 0.4 and specified concrete strength is higher than 35MPa in the concrete/building construction standard specification. Even though it has been proved that the concrete mixed with mineral admixture such as blast furnace slag and fly ash etc. have high strength and durability in previous researches, the beneficial informations are not applied to the codes. Ready-mixed concretes which usually include the admixtures in Busan were tested to certify the salt attack durability. In the same specified concrete strength, remarkable salt attack durability was evaluated in comparison to OPC. For economical and reliable durability design, chloride ion diffusivity should be measured before applying to new building construction.

The objectives of the project were to promote the mood of an old market, while preserving its functions and efficiency as a market, to design outdoor spaces with natural resources and amenities in balance, and to create attractive tourist spots in connection with the wide area development plan. The project was oriented, fast, to enhance the functions of the market. For this purpose, a multi-dimensional space layout was designed in consideration of functions as a wholesale market. The safety of pedestrians was secured by separating lathes for vehicles and for pedestrians. Tree planting with various functions such as sheltering, wind breaking and guiding was planned. Secondly, nature-friendly and human-friendly landscaping design was attempted. For this, the beautiful natural resources of Amnam Park were utilized, and green spaces such as green bridges linking buildings in the wholesale market, and rooftop gardens were to be arranged. In addition, environment-friendly facilities such as roads paved with natural materials(i.e. gravel, shells) and program parking lots were to be planned. Thirdly, landscape design was considered to create attractive tourist spots. For example, a fish farm was created as a theme street for pedestrians and various water-friendly spaces such as pedestrian ramps, observatories and seaside streets were to be secured. The main contents are as follows. First, a green bridge to Ahnnam Park was introduced for a tour source and flower garden, an event plan and viewing deck open to the sea were planned on the bridge's axis. Secondly, for the effective land use plan concerning open space and convenience to visitors, a promenade was planned, which is connected with the theme plaza and small plazas by environmental sculptures in front of the market hall and at the gate. As well, an observatory and a roof garden help create three dimensional multi leveled space, with a good view of the natural landscape of the sea, sky and park Thirdly, landscape materials, such as trees and those for facilities, strengthened for protection against the seawind and salt damage were selected. The commercial market area was intended to be transformed a traditional functional area of efficiency and economy into an attractive marine leisure area where both tourists and neighbors can make use of it.

This study characterized groundwater quality and the influence of agrochemicals in a part of Ilgwang-Myeon agricultural area in Gijang-Gun, Busan Metropolitan City, using factor analyses. From the 1st, 2nd, and 3rd analyses of groundwater samples, the mean concentrations of $Ca^{2+}$, $Na^+$, $Mg^{2+}$, $K^+$, $Zn^{2+}$, $Cu^{2+}$, $Fe^{2+}$, $Al^{3+}$, $NO_3\;^-$, $Cl^-$, $SO_4\;^{2-}$, $F^-$, and $SiO_2$ were higher in the 2nd analysis than the other analyses. Pesticide carbofuran and herbicide alachlor were detected at the wells more than a half of all the wells in the 2nd analysis but not in the 4th analysis. This fact may be explained by that a higher precipitation induced higher infiltration rate of contaminants into groundwater during the 2nd survey. According to R- and Q-mode factor analyses, and chemical composition, inorganic constituents excepting $SiO_2$, $HC0_3\;^-$-, and $F^-$ may be influenced by anthropogenic sources (manures, synthetic fertilizers, and domestic wastes), seawater as well as water-mineral interaction. A typical indicator of groundwater contamination, nitrate, exceeds around 4-5 times over the Korean standard for drinking water. Additionally, the influence of seawater diminishes from the seaside to inland.
