  • 최근 국내 신입사원 입사시험에 NCS 직업기초능력시험을 도입함에 따라 국내 각 대학교나 교육기관에서는 NCS 기반의 전공교육 및 교양교육을 도입하고 있다. 이에 따라 프로그래머를 지향하는 공학도를 위한 NCS 기반 프로그래밍 능력을 향상시켜줄 수 있는 교수-학습 지침안이 필요하게 되었다. 본 연구에서는 학습 모듈을 도출하기 위한 분석과정을 거쳐 본 교과의 학습로드맵과 NCS능력단위요소를 기반으로 학습자 스스로 NCS 프로그래밍 능력을 향상시킬 수 있는 교수-학습 모듈을 설계하였다.

  • 많은 나양한 교수법들이 존재하지만 일반적으로 공학 교과목에서는 PBL교수법과 프로젝트 팀 교수법을 가장 많이 사용하고 있다. 본 논문에서는 2018년 2학기 공학 프로그래밍 교과목을 3개를 선정하여 PBL 교수법과 프로젝트팀 교수법을 적용하였고, 두 교수법의 학습만족도, 교육성장도, 학업성취도를 설문조사하여 학습효과를 분석하여 보았다. 그 결과는 저학년은 PBL법이, 고학년은 프로젝트 팀 교수법이 학습효과가 좋았다. 따라서 같은 프로그래밍 교육이지만 학년에 따라 교수법을 달리 선택할 필요가 있다.

  • The applicability to Korea is examined of a pond system which treats and recycles wastewaters. Air temperature and solar radiation of the pond systems at Corinne, Utah, and Eudora, Kansas, which are located in temperate regions of the U.S., are compared with those of Kimpo lying in the mid-western part of Korea. Analyzed are also $BOD_5$ and SS concentrations, algal concentrations, pH levels, and water temperature of the two systems. Air temperature of Kimpo is quite similar to that of the two systems, and solar radiation of Kimpo is more conducive than that of the systems to the growth of algae during summer. Analysis of $BOD_5$ and SS concentrations in the final effluent of the systems shows that they meet the secondary treatment standards. The study demonstrates that wastewater treatment pond system which is similar in design to the systems can be reliably utilized at Kimpo, Korea. A model is proposed which can integrate a pond system with aquaculture and agriculture.

  • These experiments were conducted at field and green house in order to screen the resistant sesame varieties to Phytopthora nicotianae var. parasitica. and to ascertain the infection conditions of Corynespora cassiicola at different temperatures, soil moistures and leaf stages. Most of varieties studied in this experiment were very susceptible to the Phytopthora blight. Orotall, Suweon 7, Suweon 27 and Jochiweon were resistant to the disease. PI280795 and IS103 showed a tendency to be morderately resistant. The infected areas by Corynespora leaf blight were 15% in Kwangeui and 25% in Kimpo variety at high temperature condition of 3$0^{\circ}C$, respectively. The infection areas were 50% in Kwangeui and 70% in Kimpo variety at low temperature condition of 17$^{\circ}C$. These results indicate that the development of the leaf blight was highly increased at low temperature. The infection areas by the Corynespora were 55% in Kwangeui and 80% in Kimpo at wet soil moisture condition, and 10% in Kwageui and 15% in Kimpo at dry condition, respectively. The infection of the leaf blight was highly increased at 6 leaf stage and flowering date compared to at 10 and 20 leaf stages. The infection ratios were 20% at 6 leaf stage and 52.5% at flowering date, respectively.

  • Taegwondo uniforms need powerful durability in fabrics against friction and shock because of higher exercising power. Therefore, in this study we developed more comfortable Taegwondo uniform for functional fabrics(deodorization rate, antibacterial activity and static charge). Chitosan is a deacetylated product of chitin, has widely been used in the biomedical sector, food industry, and textile industry. For the purpose of this study, we used the chitosan, which was congenial to the human body. Then, we compared the differences between the chitosan treated fabrics and non treated fabrics of Taegwondo uniform(100% polyester, 65% polyester/35% cotton). Chitosan was dissolved in 1% acetic acid. Also, the fabrics were washed using distilled water. Afterward, its treatment with chitosan was completed by padding the sample to its wet pick-up at $80{\pm}5%$ and by heating $150^{\circ}$ for 3 minutes. The chitosan treated Taegwondo uniform was improved on deodorization rate than non treated uniform. And the chitosan treated Taegwondo uniform was improved remarkably the antibacterial activity in all samples. In the further researches, the static charge was reduced in chitosan treatment uniform.

  • Purpose - This research investigates whether e-service quality has the influence on long-term orientation, consumer commitment, and satisfaction. Research design, data, and methodology - Data collection took place for 30 days from October 1, 2015 to October 31, 2015. 315 copies had been analyzed. Covariance structure analysis with credibility and factor analysis was conducted to verify this research hypotheses. Results - First, the lower dimension concepts of e-service quality, reliability, and tangibility had a significant influence on customer commitment, and responsiveness had a significant negative influence. However, aesthetics did not have a significant influence on that. Secondly, aesthetics had a significant influence on long-term orientation, but reliability, tangibility, and responsiveness did not have a significant influence. Thirdly, reliability, tangibility, and aesthetics had a positive influence on customer satisfaction. However, responsiveness had a negative influence. Fourthly, customer commitment had a significant and positive influence on customer satisfaction, but customer commitment and customer satisfaction had a negative influence on long-term orientation. Conclusions - This research verifies the influencing relationship between e-service quality of a franchise coffee shop application with customer commitment, customer satisfaction, and long term orientation. By the results of this research, possibility of application and expansion of theory has been proven.

  • Open dump causes groundwater and soil contamination by leachate, air pollution by LFG (Landfill Gas). In this paper, in order to improve landfill researches which have been done about reduction of high leachate level and LFG collection in the Kimpo landfill separately, the effect of simultaneous flowing of leachate and LFG has been Studied. The HYLGS (Hanyang Leachate Gas Simulator) used in this study is a 3D, 2-phase, transient FDM model which can be applied to venting trenches in a landfill. From present numerical analysis it can be concluded that all the pressures of the Kimpo landfill grid system are almost the same and their maximum value in the center grid block of the system is approximately 26 m $H_2O$ (2.52 atm), that because the pressures of venting trench layer situated in the middle of the landfill have the lowest values and equal with air pressure, the venting trenches play an important role in landfill stabilization, that the flow of gas will be more difficult as time goes by owing to the increase of LGR(Leachate and gas ratio).

  • The present experiments were carried out to understand the genetic structure of the natural population by means of the frequencies of recessive lethal and sterility genes on the second chromosomes of Drosophila melanogaster. The natural populations used for experiment were Anyang, Kimpo and Ulsan populations in 1982 and 1983. The mean frequencies of deleterious gene (lethal plus semilethal) were estimated 29.01% in Anyang, 30.07% in Kimpo and 32.31% in Ulsan population. Allelism rates on the chromosome between lethals extracted from natural populations were examined within or between populations. The mean allelism rates were showed 2.28% in Anyang, 1.90% in Kimpo and 2.17% in Ulsan. The values of elimination $(IQ^2)$ were estimated by frequencies of deleterious genes and allelism rates. The mean values of elimination were 0.0020 in Anyang, 0.0019 in Kimpo and 0.0023 in Ulsan population. The effective population size was estimated by using a formula by Nei. Anyang, Kimpo and Ulsan populations were about 2, 900, 3, 600 and 3, 200, respecively. These data suggest that Korean populations of Drosophila melanogaster attained to stable breeding units of intermediate size, ranging from 2, 900 to 3, 600 pairs of fertile individuals.
