온라인 게임의 인기가 증가하면서 희소성 있는 재화를 현금으로 바꾸는 RMT (Real Money Trade) 유저들이 증가하였고 이를 전문적으로 이용하는 게임 내 범죄 집단인 GFG (Gold Farming Group)이 나타났다. GFG는 게임재화를 수집하기 위해서 다수의 봇 계정이 필요한데, 이를 위해 명의 도용, 개인정보 유출 문제를 발생시키게 된다. 또한 현금거래를 유발시켜 게임 내 경제의 형평성을 파괴하고, 계정 도용, 아이템 탈취를 유발 시킨다. 따라서 GFG를 제거 및 차단하는 일은 사회적, 게임 내 관점에서 중요한 문제이다. 본 논문은 기존의 판매자 관점의 탐지가 아닌 수요공급의 원칙에 따라 현금거래 구매자를 탐지하는 근본적인 방안을 제시하였다. 실제 게임 데이터를 분석하여 두 가지의 RMT 형태를 발견하였고, 구매자 탐지의 재현율이 98%이상을 보일 수 있었다.

Since the number of students in farming and fishing communities have been widely decreased due to industrialization and urbanization along with a low birth rate. As a result, the number of closed schools has reached 3,386 in 2010. The number is still increased because of continuous decrease in the number of population engaged in farming and fishing. Explore the possibility for the development of closed schools facilities, this researching is showing us that the closed schools have associated with the local community closely. For this reason, we need to promote these closed school facilities to utilizing purposes as appropriate to the needs of the times and with that we can explore too the possibility of a variety of regional development concept, how underdeveloped regions can be activated. Therefore, first on this study is progressed theoretical study of utilizing of closed schools and the strengthening of regional competitiveness as a framework and we consider characteristics of the closed schools utilizing. Second, we choose the case, where the utilizing of closed schools have realized to purpose of regional development conceptions with the strengthening of regional competitiveness. Third, we would like to prove several possibilities with results of date-analysis and formulate some suggestion for be continued future planning of utilizing of closed schools. education.

Bacillus is a diverse genus consisting of more than 200 species with extensive genetic diversity. Their beneficial effects in industrial shrimp farming have been well documented. However, little is known about the biodiversity of the Bacillus spp. in this aquaculture system. Taxonomic analysis by 16S rRNA sequencing does not always allow species-level identification of Bacillus spp. In this study, 26 Bacillus isolates from two industrial Litopenaeus vannamei shrimp ponds in Bac Lieu Province, Vietnam, were analyzed for their genetic diversity by multi-locus sequence typing (MLST). A total of 22 sequence types were identified and segregated into four distinct clusters, corresponding to B. subtilis, B. velezensis, B. siamensis, and B. licheniformis. Bacillus subtilis and B. velezensis accounted for more than 73% of the Bacillus isolates. Notably, the MLST scheme exhibited high discriminatory power and might be further simplified to be a convenient method to identify species of the genus Bacillus.

The feasibility of precision farming for small sized fields was studied by determining fertilizing amount of nitrogenous and calcareous to a cite specific region. A detailed soil survey at three experimental fields of 672㎡, 300㎡ and 140㎡ revealed a considerable spatial variation of the pH and organic matter(OM) levels. Soil organic matter was measured using Walkley-Black method and soil pH was measured with a pH sensor. Soil sample was obtained by Grid Node Sampling Method. The soil sampling depth was 10 - 20 cm from the soil surface. To display soil nutrient variation, a soil map was made using Geographic Information System (GIS) software. In soil mapping, soil data between nodes was interpolated using Inverse Distance Weighting (IDW) method. The variation was about 1 - 1.8 in pH value and 1.4 -7 % in OM content. Fertilizing Amount of nitrogenous and calcareous was determined by the fertilizing equation which was proposed by National Institute of Agricultural Science and Technology.(NIAST). The variation of fertilizing amount was about 3 - 11 kg/10a in nitrogenous and 70 - 140 kg/10a in calcareous. The results showed a feasibility of precision fertilizing for small size fields.

The movements of three striped jack (Caranx delicatissimus, 24cm of body length) were tracked by ultrasonic telemetry in the Nunoura Bay in August 1990. A school of the striped jack has been released near by the fish farming rafts by Goto branch of the Fisheries Agency and Japan Sea-Farming Association. To investigate the staying area and the swimming pattern of the fish, small size pinger($\Phi$8.5$\times$L35mm, 140dB re 1$\mu$Pa at 1m, 69kHz) was tagged on the dorsal fin without any anesthesia. The movements of three tagged fish are monitored at the same time with four omni-directional hydrophones. The locations of the fish are calculated by the hyperbolic method and tracked by a technique so called time division scheme which uses both the pulse interval and the phase. Three pingers used have the pulse interval of 1.7, 1.8 and 1.9sec, respectively, and the common pulse duration of 15ms. In results it was capable to estimate behavior right after the release, swimming speeds and approximate moving area of the fish. The movements were tracked for a week continuously, and it was found out that the staying area of the fish was around or under the farming rafts. Sometimes they swam together but most of the time they move separately. The average swimming speed of those fish was about two times of the body length.
