In this study we examined the preferences of college life factors for students at Korea National College of Agriculture and Fisheries(KNCAF). Analytical techniques of unstructured data used opinion mining and text mining techniques, and the results of text mining were visualized as word cloud. And those results were used for statistical analysis of the students' willingness to farm after graduation. The items of the favorable survey consisted of 10 items in 5 areas including university image, self-capacity, dormitory, education system, and future vision. After classifying the emotions of positive and negative in the collected questionnaire, a dictionary of positive and negative was created to evaluate the preference. The items of 'college image' at the time of university support, 'self after 10 years' after graduation, 'self-capacity' and 'present KNCAF' showed high positive emotion. On the other hand, positive emotion was low in the items of 'college dormitory', 'educational course', 'long-term field practice' and 'future of Korean agriculture'. In the cross-analysis of the difference in the will to farming according to gender, farming base, and entrance motivation, the will to farm according to gender and entrance motivation showed statistically significant results, but it was not significant in farming base. Also in binary logistic regression analysis on the will to farming, the statistically significant variable was found to be 'motivation for admission'

This study was conducted to investigate the seed storage method and seed germination characteristics of Synurus deltoides (Ait.) Nakai, a kind of wild vegetables. Several parameters affecting seed germination, such as germination temperature, chilling duration, imbibition duration, and storage method were evaluated. The seed germination of Synurus deltoides showed the highest germination rate (GR), promptness index (PI), germination performance index (GPI), mean daily germination (MDG) at 25℃. This implies that the optimum germination temperature was 25℃. And also, Seeds stored at -4℃, after 150 days showed relatively high germination rate about 98%. Therefore, The optimum germination temperature of Synurus deltoides was 25℃ and to increase the germination rate over 98% of Synurus deltoides, cold-wet storage 20 days treatments at 4℃ were effective in the improvement of seed germination.

In this paper, we surveyed the service system disclosed by the government and self-governing province to analyze the status of IoT data service. Survey conditions were focused on data generated from objects such as sensors, OpenAPI that can utilize the generated data and data having a data update cycle of less than 1 month. As a result of the survey, the ratio of IoT data to data released by the government, self-governing province and the private sector was only 1.2%. Therefore, in order to increase the utilization with the development of IoT technology, a dedicated organization that can manage the IoT data service is needed.

This study analyzed the executive characteristics of farmers in the achievement contents of prize winners who can be called advanced farmers. According to the analysis, advanced farmers were responsible for developing new agricultural technologies and extending into farmers in the 1990s to increase productivity. In the 2000s, individual farmers were organized to contribute to regional agricultural development by the advanced farmers. In the future, advanced farmers should play a role in the sustainable agriculture through the multi functional value oriented agriculture.

This study was carried out to establish a proper cultivation site and to diagnose the drought tolerance of Oplopanax elatus leaves by using pressure-volume curves. As a result of analysing data measured, the leaf of Oplopanax elatus showed the osmotic pressure at full turgor(Ψosat) was -0.77 MPa, and the osmotic pressure at incipient plasmolysis(Ψotlp) was -0.90 MPa. Then, the value of maximum bulk modulus of elasticity Emax was 3.7 MPa, showing that slightly lower drought tolerance of Oplopanax elatus. Furthermore, the values of relative water contents RWCtlp and RWC^* were above 80%, showing that the function of osmoregulation is somewhat better. Thus, responses to water relations such as Ψosat, Ψotlp, Emax, RWCtlp and RWC^* of Oplopanax elatus showed relatively lower drought-tolerance property indicating that those growth are appropriate in high moisture soil sites.

This study utilizes DEA/Window analysis in order to investigate the relative efficiency levels of korea national university libraries during the period of transition 2004-2008. The empirical results show the following findings. Firstly, a technical efficiency was not efficient which was a scale efficiency rather than a pure technical efficiency in 2008. Secondly, a technical and pure technical efficiency has increased steadily from 2004 to 2008(but a technical, pure technical efficiency has decreased since in 2008). As a result, a technical efficiency increase can be explained by a pure technical efficiency increase.

The purpose of this study was to investigate ways to improve the effect of English-medium instruction (EMI) in Korean universities by comparing EMI lectures in two Korean universities with those in a Japanese university. Some universities run all courses in English while others do so for only part of them. This study comparatively investigated how EMI courses were run by these two groups of universities. For the purpose of this study, in-depth interviews were conducted with EMI instructors and students to find out what merits and problems that such EMI programs had in EFL environment of Korea and Japan. Another important goal was to correct problems and improve the Korean programs. The result showed that the most important issue of EMI programs in Korean universities was students' low English proficiency. It also demonstrated that English for Academic Purposes (EAP) was necessary to overcome this problem. It is a key to the success of MI programs. Hopefully, this study will stimulate continuous discussions on limitations and ways to improve EMI in Korean universities in various aspects.

Data Envelopment Analysis(DEA) model is a linear programing based technique for measuring the relative performance of organizational units where the presence of multiple inputs and outputs makes comparison difficult. DEA model allows each unit to adopt a set of weight that shows it in the most favorable light in comparison to the other units. The purpose of this study was to evaluate the performance of the libraries of national university in terms of relative efficiency, measured by the method of DEA. Twenty six libraries of national universities in Korea were used to analyze. The number of employees, size of library, budget, and number of books were used for input data, and the number of visitors, number of loan books, and number of books for lending and borrowing were used for output data. We found out that number of libraries with 100% relative efficiency among 26 libraries from 2005 to 2007 were only 9, 9 and 10, respectively. Moreover most of the libraries need to increase outputs and decrease inputs in order to improve efficiency.
