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.

Judicious control of high temperature is the most important task for the successful intensive-cultivation of vegetables in glasshouses during the hot summer. Estimation of cooling load and wise selection of suitable equipments and facilities based upon the environmental conditions are essential for the efficient temperature control. A series of experiments were carried out to investigate VETH(ventilation, evapotranspiration, temperature and humidity) plot was prepared for the possible practical application in designing some evaporated cooling methods for the following 9 locations; Seoul, Seosan, Taejeon, Pusan, Cheju, Kwangju, Taegu, Chonju, and Chinju.

This study was conducted to describe the relationship of Career Identity and College Adaptation of student at agricultural special purpose academies. The participants were 335 college students in H city from November 2 to December 12 in 2016. The data was collected by questionnaires and was analyzed using SPSS 23.0. There was a significant positive correlation among Career Identity and College Adaptation of college students. It was found that the effect of Career Identity on College Adaptation was 42.0%. The results of this study provided a foundation to recognize importance of College Adaptation and to develop intervention program to improve College Adaption and Career Identity of student at agricultural special purpose academies.

Vaccination for swine food and mouth disease (FMD) has been using needle injection. Needle injection can cause lesions of injection site on muscle and lymph node, leading to consumer's complain and Korea Pork's image deterioration. Needle-free injections have been developing to solve this issues. The current study performed to evaluate the frequency of muscle and lymph node lesions after vaccination using needle-free injection. Needle-free injection significantly decreased the lesions on the injection site compared with the needle injection(36 vs. 16%, p < 0.05). Based on the result, needle-free injection can enhance the quality of pork and decrease consumer's complains. Further study should perform to validate potential of needle-free injection by investigating antibody formation rate, work efficiency, and economic cost.

The purpose of this study is to suggest strategies for vitalizing Jeju citrus export-specialized organization. To achieve the goal, the research has been focused on the establishment and standardization for fruit production practices that can keep a steady supply of high quality citrus fruit for export market, and followed by systematization of farms using the practices. According to the research findings, it is desirable that the high quality fruit production manual such as the Global GAP must be established, developed and prepared to train farm households. The establishment of the high quality fruit production manual is focused on the items as follows : 1) labor productivity enhancement by structural improvement of farm layout, 2) the practices for high-sugar-fruit production such as thinning out, irrigation and drainage system, and mulching with a poromeric sheet 3) productivity enhancement and quality improvement of fruit by cultivar improvement and virus-free nursery trees, 4) standardization of cultural practices throughout the citrus fruit production.
