Objective: This study carried out base research to build an agricultural safety monitoring system through ICT convergence to reduce safety accidents and enhance welfare in life in the agricultural field. Background: The functions and values of rural villages as the space of living are recognized anew, but occupational accident rate due to farm work accidents is on the rise each year. Therefore, the seriousness of such a problem emerges. The convergence technology combining ICT is recently applied to industries overall, and therefore better services are offered. However, studies on ICT convergence has not yet been applied to the agricultural safety field. Method: This study identified ICT convergence service technology trends and representative serious accident types mainly occurring in agricultural activities. This study defined the major factors of farm work accidents and ICT to solve those accident factors including the sensor technology, wired/wireless communication technology and location information service, and applied them to prototype PCB for the development of an agricultural safety monitoring system. Results: This study proposed an emergency monitoring system for farmers and a harmful environment monitoring system. The ICT technology to prevent farm work accidents can be summarized as sensing technology, ICT and network technology and user interface technology. This study also designed PCB module configuration and situation judgment algorithm as basic research for proposed monitoring system development. Conclusion: The ICT-based agricultural safety monitoring research proposed in this study is expected to become the basis to build a future real time monitoring system, and also is expected to contribute to social safety and welfare service improvement for farmers. Application: The ICT convergence farmer accident prevention system will make contributions to the prevention of serious farm work accidents.

Rural and agricultural landscapes are important forms of land use in maintaining biodiversity. In addition humans are provided with various public functions from ecosystems and agricultural ecosystems. But the creation of a facility horticultural complex can be a space that can undermine the public interest function of the agricultural ecosystem. Therefore, this study aims to quantify the function of ecosystem services that land use changes affect biodiversity in Korea's rice paddy fields. The area subject to the study was selected as the largest agricultural complex in Korea due to rice paddy fields and land use changes, and field agriculture was also carried out simultaneously. The survey was conducted only in the fields of vegetation, insects, amphibians, and birds, four areas of biodiversity that are believed to have a high impact on changes in land use in agricultural landscapes. The valuation of ecosystem services in four areas of biodiversity derived from this study was evaluated as non-market value. As a result of quantitative evaluation, about 25 species of vegetation were reduced due to changes in land use. The diversity of about 40 species of aquatic insects that inhabit rice paddies among insects has disappeared due to the creation of a horticultural complex. Birds and amphibian reptiles were also found to have decreased diversity and populations. This research is expected to be used in various ways to develop policies to enhance ecosystem service functions.

Research confirms that healthful benefits accrued when people connect with nature and insect by viewing and interacting with them. Insect rearing is easy, relatively inexpensive, and can breed small space. This study aimed to investigate the physiological effects of animal assisted activity using insect(Oriental garden cricket) with diets and a rearing manual. The group of insect activity whose ages ranged from 65 to 82 years old that attending a community center in Daegu, Korea, were enrolled in the study between April and May 2014. The collected data was analyzed using qualitative analysis. Qualitative study is utilized to explore mental models, and their linguistic, affective, cognitive, social and cultural significance. The result showed that people-insect interactions promote well being of the elders, and the important aspect of insect activity aids in improvements in their social, emotional and cognitive functioning which were enhancing life satisfaction, reducing loneliness and increasing activities of daily life.

D-Psicose 3-epimerase (DPE) catalyzes the interconversion of D-fructose to D-psicose by epimerizing the carbon-3 position. The DPE from Agrobacterium tumefaciens was cloned and expressed in Escherichia coli. The expressed enzyme was purified by affinity chromatography on an IMAC, gel filtration chromatography on a Sephacryl S-300 HR, and anion-exchange chromatography on a RESOURCE Q. The molecular mass of the purified enzyme was estimated to be about 135 kDa by Superdex 200 gel filtration chromatography, corresponding to a homotetramer. The enzyme produced crystals suitable for X-ray diffraction to a $2.0{\AA}$ resolution at 100 K. The crystals were found to belong to the orthorhombic space group $P2_12_12_1$, with unit-cell parameters a=102.4, b=113.0, and $c=131.8{\AA}$. In addition, the calculated packing parameter $(V_m)$ was $2.79{\AA}^3/Da$, the solvent content was 55.92%, and an asymmetric unit consisted of four monomers.

Germinatin and early growth of tobacco seedlings in trays containing many cells is increasing in popularity . Since 100 % germination is not likely , a major problem is to locate and replace the content of those cells which contain either no seedling or a stunted seedling with a plug containing a viable seedling. Empty cells and seedlings of poor quality take up valuable space in a greenhouse. They may also cause difficulty when transplanting seedlings into the field. Robotic technology, including the implementation of computer vision, appears to be an attractive alternative to the use of manual labor for accomplishing this task. Operating AGBOT, short for Agricultural ROBOT, involved four steps : (1) capturing the image, (2) processing the image, (3) moving the manipulator, (4) working the gripper. This research seedlings within a cell-grown environment. the configuration of the cell-grown seedling environment dictated the design of a Cartesian robot suitable for working ov r a flat plane. Experiments of AGBOT performance in transferring large seedlings produced trays which were more than 98% survived one week after transfer. In general , the system generated much better than expected.

The agricultural tourism is something that urban people can have an experience of the traditional culture and knowledge of the agriculture, so that it result the improvement of the agricultural profit and keep the special agricultural system. Recently, the demand of the agricultural tourism was increasing, but it was not really enough today that the practice of the tourism for essential farm experience or physical plan. The experiments were practiced by a land in Sucheong-li, Namjong-myun, Gwangju-si, Gyeonggi-do which provides the program for the basic plan and management of the experiential farm, so it shows a developmental model of that typical farm. The basic design of developmental model was formed by the analysis of the natural, civilized and visual environments. The site plan for the experiential farm was composed of a parking lot, public facilities, resting place, experiential site, sports facilities and pedestrian space. There was an examination that the activation of experiential farm should change the concept of the big production or labor-focused farm from a tourism-focused form.
