The purpose of this study is to verify and carry out action plan and issues on how local amenity can be revealed through rural village planning and design especially in the local resources such as nature, history, culture. Especially, this lead to macro view of the rural village plan i.e. related to rural identity and space planning via estimating the local resources. According to this study will plan of 4 phrase steps 1. Analyse nature, environment, human sociology environment, space etc., and comprehensive analysis 2. compare the results of estimation and find the planing factors after that set the planning process 3. plan and create to rural community i.e. considering harmony with space function, environmental circumstance, landscape etc, 4. suggest the rural community action plan by considering amenity attributes.

The probability of landslide hazards was predicted to natural terrain around the stone relics of Jinjeon-saji area, which is located in Yangyang, Kangwon Province. As the analysis results of field investigation, laboratory test and geology and geomorphology data, the effect factors of landslides occurrence were evaluated, and then the landslides prediction map was made up by use of prediction model considering the effect factors. The susceptibility of stone relics induced by landslides was investigated as the grading classification of occurrence probability using the landslides prediction map. In the landslides prediction map, the high probability area of landslides over 70% of occurrence probability was 3,489m3, which was 10.1% of total prediction area. If landslides are occurred at the high elevation area, the three stories stone pagoda of Jinjeon-saji (National treasure No.122) and the stone lantern of Jinjeon-saji (Treasure No.439) will be collapsed by debris flow.

Climatological trend for the period of 1970 to 2009 in sea water temperature around the Antarctic Peninsular waters in the Southern Ocean was investigated. During the period from 1970 to 2009, sea water temperature in the top 500 m water column except 100 m increased at a rate of $0.003-0.011^{\circ}C{\cdot}yr^{-1}$, but at 100 m it decreased at a rate of $-0.003^{\circ}C{\cdot}yr^{-1}$. Although long-term trend is generally warming, there were several periods of sharp changes between 1970 and 2009. Annual mean sea water temperature between surface and 500 m except 100 m decreased from the early of 1970s to the end of 1980s, and then it increased to the end of 2000s. In the entire water column between the surface and 500 m, sea water temperature closely correlated with the El Nino events expressed as the Southern Oscillation Index(SOI), and SOI and sea water temperature have a dominant period of about 3-5 years and decade.

This research is inquired to the residents in Kimcheon, Kyongsang-Boukdo and in Kangnung, Yangyang, Kangwon-Do. The residents were damaged by typhoon ${\ulcorner}RUSA{\lrcorner}$ in 2002, which occurred the biggest damage in our country's natural disaster. The result of inquiry is arranged in this research. Inquiry contents arrange a current events points through the inquiry. which is about the resident's demand and confrontation caused by a big disaster occurrence; the damage present condition which is caused by typhoon ${\ulcorner}RUSA{\lrcorner},$ the countermeasure condition on damage occurrence, the necessity content of area disaster information, the difficulty factor of damage restoration, the evaluation of the government and relation group's countermeasure which is about typhoon ${\ulcorner}RUSA{\lrcorner},$ the mental and body problem after disaster occurrence. And inquiry contents present the fundamental data for establishing the area prevention of disaster plan hereafter.

Stability and durability of the artificial reefs (ARs) installed for wildstock enhancement have been a key issue. We surveyed the stability of 4,044 artificial reefs installed at 5 sites (Gangeung, Donghae, Samcheok, Goseong. and Yangyang) along the Gangwon coast of the East Sea (Sea of Japan) through which 1 to 5 typhoons pass annually. The ARs surveyed were 7 types aging 1 to 4 years. The side scan sonar (SSS) and scuba diving surveys confirmed that the ARs stability was age and type-dependent. A total of 85.56% ARs remained safe. the rest 14.44% being influenced by physical parameters of the waters such as wave extremes mostly caused by typhoons. An interesting observation was that the AR were particulatly vulnerable to the wave extremes in the first year of installation, thereafter being less damageable. Representative damages of the ARs were capsized (0.20%). broken (5.79%), sunk (0.27%), and buried (8.18%). By type, dice reef was most stable. while semicircle branch reef was most vulnerable.

We investigated the genetic structure of Korean and Japanese ayu Plecoglossus altivelis populations by examining 669 individuals from 14 populations using three microsatellite loci. Genetic variation did not differ significantly among the populations examined in terms of allelic number and heterozygosity. Korean populations were genetically close to each other, implying that persistent gene flow has occurred in these populations. This suggests that eastern populations in Korea form a single large population and all of the Korean populations are distinct from the Japanese populations. Pairwise population $F_{ST}$ estimates, principal component analyses, and a neighbor-joining tree showed that genetic separation between the southern and pooled eastern coast populations was probably influenced by restricted gene flow. Hierarchical analysis of molecular variance (AMOVA) revealed a weak but significant genetic structure among three ayu groups (eastern and southern coasts of Korea and the Japan coast), and no genetic variation within groups. The estimated genetic population structure and potential applications of microsatellite markers may aid in the proper management of ayu populations.

Genetic diversity and gene flow patterns in Pollicipes mitella were investigated with a nucleotide sequence analysis of 514 base pairs from the mitochondrial cytochrome c oxidase subunit I gene (COI) in 124 samples collected from six Korean populations. In total, 59 haplotypes were defined by 40 variable nucleotide sites in the COI region. The haplotypes had shallow haplotype genealogy and no geographic associations. All populations had high haplotype diversity (0.909 to 0.979) and low nucleotide diversity (0.0055 to 0.0098). The haplotypes with recently diverged nucleotides were distributed by long-range larvae dispersal among regional populations. The pairwise fixation indices ($F_{ST}$) estimated with the exact test and migration rates indicate that substantial gene flow has occurred among populations as a result of sea currents, except between the Uljin (East Sea coast) and other Korean populations. This suggests that significant genetic differentiation and low migration rates have affected the Uljin population.

We propose an experimental holographic imaging scheme combining compressive sensing (CS) theory with digital holography in phase-shifting conditions. We use the Mach-Zehnder interferometer for hologram formation, and apply the compressive sensing (CS) approach to the holography acquisition process. Through projecting the hologram pattern into a digital micro-mirror device (DMD), finally we will acquire the compressive sensing measurements using a photodiode. After receiving the data of two holograms via conventional communication channel, we reconstruct the original object using certain signal recovery algorithms of CS theory and hologram reconstruction techniques, which demonstrated the feasibility of the proposed method.

The amount of home deliveries are increasing day by day owing to the increment of the on-line market. This environment brings along generating many delivery companies and keen competition with each other in its customer hold Therefore, this study aims at the development of a shortest delivery route search demonstration system using Ant Algorithm. The developed system reduces the time consumption significantly in search of delivery path and time of the products for the novice delivery driver as well as experienced driver. Ultimately, the developed system will give the customer reliability and satisfaction, knowing a delivery route in advance.

This study was carried out to classify the arthropods inhabited in pine mushroom (Tricholoma matsutake Singer). The arthropods were collected in a state forest (196 compartment, 157ha) located in Yangyang-gun, Kangwon-do. After collection the arthropods were classified in laboratory. The results obtained are summarized as follow; 1. Insects inhabited in pine mushroom are in total 19 Families of 7 Orders. Some animals in Araneina, Acarina, Nematoda and Stylommatophora were also observed, 2.
