This study was conducted to monitor the current status of pesticide residues and to calculate the correlation between monthly price fluctuation and distribution of pesticide residues in leafy vegetables at the whole market in Gyeonggi-do from 2009 to 2013. From the result, the maximum residue limit (MRL) were frequently exceeded in 5 leafy vegetables which were 48 cases of crown daisy (5.8%), 28 cases of chard (5.1%), 28 cases of spinach (3.4%), 25 cases of perilla leaves (3.4%) and 24 cases of chamnamul (3.7%). The high rate of monthly pesticide residues exceeding MRL showed on crown daisy and chard observed in June and September, spinach in October to November and December to January, perilla leaves in July to August and January, and chamnamul in August to September. To calculate the correlation between monthly price fluctuation and distribution of pesticide residues, we performed the Pearson’s correlation analysis. From the results, there were significant differences between monthly price and pesticide residues detected in chamnamul, spinach and perilla leaves (p<0.05). There were also significant differences between monthly price and pesticide residues exceeding MRL in chamnamul and crown daisy (p<0.05). Although the small number of leafy vegetables and short period were analyzed in this study, the consolidation monitor of pesticide residues according to the season and price will be needed to acquire the safety of agricultural products.

A port, where tens of thousands of containers are stored and forwarded each day, is an ideal site to which the ubiquitous communication infrastructure can be established to enhance the throughput. To design a communication protocol for ubiquitous sensor networks which monitors containers in a port, we need a mobility model for the containers. However, most prior mobility models target the movement of humans or vehicles in spaces such as a campus or a theme park. There is no suitable model for containers in a port yard. In this work, we first propose a method of simulating the movement of containers in a port yard based on the analysis on the port operations such as, imports, exports, and intra-port transports. Then we propose a general mobility model which can be applied to ports with different scales and infrastructures. This general model is validated by comparing to simulation results.

생육형이 다른 대맥품종을 혼파하였을경우 품증종에 일어나는 경합상을 구명하기 위하여 본실험을 행하였던바 그결과를 요약하면 다음과 같다. 1. 장기종인 브흥은 단간종인 수원18호 보다 경합능력이 현저히 높았으며 이러한 경향은 보비구에서 보다 배비구에서 더욱 현저 하였다. 2. 혼파했을 경우 장기종의 간장은 짧아지고 단간종의 간장은 길어 졌으며 이와 반대로 수장에 있어서 단간종은 오히려 짧아지고 장간종은 길어졌다. 3. 수수 및 일수립수는 처리간 차이가 인정되지 않았다. 4. 단파의 경우 수원18호는 보비구가 배비구보다 약간 수량이 많았고 이와 반대로 부흥은 배비구가 보비구보다 현저히 수량이 많았다. 그러나 혼파의 경우에는 전체적으로 배비구에서 보비구보다 현저한 수량의 증가를 나타내고 있다. 5. 장기종인 부흥이 단간종인 수원8호보다 현저히 경합력이 우세하였으며 이러한 경향은 시비량이 증가될수록 크게 나타난다. The experiment about the mixed sowing of two different growth type varieties of barley-Buheung and Suwon#18-has been conducted to determine the competition effect between two varieties, and its results are as follows: 1. Buheung-long stem variety-showed higher survived ratio than Suwon#18-short stem variety- and that tendency was significant under the high fertilized condition. 2. When tow varieties-Buheung and Suwon#18-were sowed together, the culm length of Buheung was shorter than the single planted Buheung and that of Suwon#18 was onger than the single planted Suwon#18, however, the panicle length showed the opposite tendency to the culm length variation. 3. The number of panicles and the number of grains did not show any differences among the treatments. 4. In case of the single sowing, Suwon#18 showed higher grain yield under the common fertilized condition but Buheung showed significantly increased grain yield under the heavy fertilized condition, however, in case of the mixed towing of two varieties, the grain yield was significantly increased in heavy fertilized plots than standard fertilization. 5. The competition power was significantly superior in Buheung to Suwon#18 and this tendency was rather definite according to the fertilizer application.

Background: Carbapenem-resistant Enterobacterales (CRE) are increasing rapidly worldwide, posing a major threat to global health. This study aimed to identify the epidemiological characteristics of CRE isolated in Gyeonggi-do according to hospital type. Methods: We conducted antibiotic susceptibility and genetic tests for carbapenemase-producing Enterobacterales (CPE) among 1,243 clinical isolates of CRE from Gyeonggi-do in 2019. CRE strains were identified using MALDI-TOF (Microflex, BRUKER, Germany), and antimicrobial susceptibility tests were performed using the broth microdilution method, according to the CLSI guidelines. Genetic testing of the CPE type was performed for KPC, NDM, OXA-48, IMP, VIM, and GES. Results: Most CRE infections in Gyeonggi-do occurred in general hospitals (60.9%) and long-term care hospitals (27.8%). While the proportion of the CPE group in general hospitals was low (55.7%), 85.0% of CRE isolates in long-term care hospitals were identified in the CPE group. In the CPE group, the proportion of CRE isolates above the minimum inhibitory concentration of carbapenem namely meropenem, imipenem, and doripenem was 76.0%, 90.2%, and 66.5%, respectively. The non-CPE group showed a relatively low resistance percentage (44.6% [meropenem], 27.6% [imipenem], and 25.2% [doripenem]) compared to the CPE group. Furthermore, we found a correlation between CPE genes and carbapenem resistance rate on the Kruskal–Wallis test (P≤0.05). Conclusion: Carbapenem resistance rate and the genetic characteristics of CRE isolates differed according to the type of hospital in which they occurred. The high proportion of the CPE group in long-term care hospitals indicates the need for more attention to strict infection control in these hospitals.
