본 연구는 국내외 경제변화가 인천경제 및 인천국제공항에 미치는 영향에 대한 실증적 분석을 시도하였다. OECD회원국, 인천광역시와 인천국제공항을 연구대상으로 2001년 인천국제공항 개항 이후 11년간의 경제변화를 시계열 자료를 이용하여 다중회귀분석과 경로분석을 시도하였다. 연구결과, 국내외 경제변화는 인천경제 및 인천국제공항의 성장 및 활성화에 정(+)의 영향을 보여주지 않았으며 국제경제요인은 인천경제에 직접적으로 정(+)의 영향을 보였으나 한국경제와 연관된 총 효과는 부(-)의 영향을 보였다. 따라서 인천경제는 국내외 거시경제변화요인에 능동적으로 대응해야 할 뿐 만 아니라 내발적 성장방안이 요구되며 이를 위한 방법론으로 공항도시 조성의 필요성을 제시하였다.

This study was conducted from May to December 2016 to investigate the prevalence of antibody titers for Newcastle disease (ND), Infectious Bronchitis (IB), Egg drop syndrome (EDS), Avian pneumovirus (APV), Fowl Typhoid (FT), Mycoplasma gallisepticum (MG), Mycoplasma synoviae (MS) in laying hens in Incheon area. In ND, 418 (99.5%) of the 420 outbreaks were positive. IB showed 330 (78.5%) positive antibody out of 420 cases. EDS showed 419 (99.7%) positive seropositive rates among 420 cases. In the case of APV, 357 cases (85%) were positive in 420 cases. In the case of PT, the positive rate of antibody was 128 (30.4%) out of 420 cases. Among the 420 cases of MG, 222 cases (52.8%) were positive for antibodies. In the case of MS, 395 out of 420 cases (94.0%) were positive. This result suggests that the positive rate of antibody for PT in Incheon area was low. And it was also clear that MS without vaccine is now rampant in Incheon.

The purpose of this survey was to investigate the status of dietitians' nutrition management in school lunch program. Questionaries were distributed to 233 dietitians of elementary schools and 10 dietitians of high schools in Seoul and Incheon provinces. The statistical analysis of data was completed using SPSS program. The results were summarized as follows : 78.4% of Seoul and 48.6% of Incheon among the whole students were served their meals in the classrooms. 70.0% of dietitians were 30-39 years old and 31.4% had a career less 5-7 years old. The standardized recipe was used in 71.6% of total schools but not effectively in both provinces. The students' nutrition and preferences were the very first to be considered in menu planning in both provinces. The nutrient value of meals was evaluated by the dietitians in most schools. Nutrition surveys of the meals which students are eating at home were surveyed in 27.3% of Seoul and 53.2% of Incheon. Students' preferences were studied regularly in 65.4% of Seoul and 78.9% of Incheon, and students evaluations of meals were carried out by the school lunch program in 74.6% of Seoul, and 68.8% of Incheon. In 49.6% of Seoul and 53.2% of Incheon, leftover foods were measured for each meal. 38.5% of Seoul used per a week and 48.6% of Incheon used per 2-3 week the processed foodstuffs. In 17.2% of Seoul and 25.2% of Incheon, nutrition education was executed by direct education, but educational methods were done mostly by letterssent to students' parents(76.9% of Seoul and 85.3% of Incheon). Evaluation studies on nutrition management, and nutrition education were hardly correlated to the dietitian's career and educational level. The number of meals served by the school lunch program have no related with the students' preferences. For improvement of nutrition management of school lunch program, it is necessary to develop new nutrition management model and nutrition education program.

Objective: The purpose of this study was to investigate the effect of acute transcranial direct current stimulation (tDCS) on the isokinetic muscular endurance of the lower extremity for young adults. Method: Thirteen young adults performed isokinetic fatigue tasks for two experimental conditions including real tDCS and sham stimulation protocols. Before and after the task, the tensiomyography was used for evaluating muscle contraction characteristics of vastus medialis and semitendinosus. Paired t-test was performed to compare the fatigue index, changes in maximum radial displacement (∆Dm), delay time (∆Tc), and velocity of contraction (∆Vc) between tDCS conditions. Results: We found no significant differences in the fatigue index between real and sham conditions. In addition, the analyses identified no significant different values of ∆Dm, ∆Tc, and ∆Vc in the vastus medialis and semitendinosus between real and sham conditions. Conclusion: These findings suggest that the tDCS protocols may have no acute effect on lower limb muscle endurance for young adults. Future studies should consider the long-term effects of repetitive tDCS sessions, various stimulation positions, exercise tasks, and participant characteristics to more clearly understand the effect of tDCS on muscle endurance of lower extremities.

Cell separation from a heterogenous mixture sample is an essential process for downstream analysis in biological, chemical, and clinical applications. This study demonstrates an integrated hybrid device of the viscoelastic focusing in a straight rectangular channel and subsequent size-based separation using acoustophoresis to attain high efficiency and separation tunability. For particle pre-alignment in a viscoelastic fluid, the flow rate higher than 10 μl/min was required. Surface acoustic wave-based lateral migration of particles with different sizes (13 and 27 ㎛) was examined at various applied voltages and flow rate conditions. Therefore, the flow rate of 100 μl/min and the applied voltage of 20 V_pp can be used for size-based particle separation.
