The 6th industrialization, which is the policy strategy to combine the 1st, 2nd, 3rd agro-food industries in order to create synergy effects, is one of the most important policy strategies for the Korean government. Local governments as well as the central government, especially the Ministry of Agriculture, Food and Rural Affairs, have introduced various specific programs for the 6th industrialization. Among them, the 6th industry antenna shops located in Cheonan and Daejeon which were introduced by the Chungcheongnam-do Provincial Government to offer a better market place for 6th industry producers. However, few studies have been conducted to evaluate the performance of 6th industry antenna shops. The purpose of this paper is to analyze consumers' satisfaction of 6th industry antenna shops through survey and econometric modeling and to present some implications of the better operation of the 6th industry antenna shops. The results of the studies in this paper present some of the following findings: first, the overall level of satisfaction towards 6th industry antenna shops is high but consumers still claim some problems. Second, products which are sold at 6th industry antenna shops have important problems, including high prices and deficient product variety. Third, if these problems were fixed, the operation of 6th industry antenna shops would be successful and contribute to the development of 6th industrialization in Korea.

지구 온난화의 주 원인인 온실가스의 배출을 감소시키기 위해서 바이오연료에 대한 필요성 및 중요성이 제기되어 왔다. 이미 유럽을 중심으로 오래전부터 바이오디젤 연료에 대한 연구가 시작되어 왔으며 지금은 상용화 단계에 접어들고 있는 반면, 국내 바이오디젤 연료에 대한 연구 수준은 이제 시작단계에 불과한 실정이다. 바이오디젤 연료로 사용가능한 유지작물의 지방산 조성에 따라 자동차 엔진 성능이 저하될 수 있다는 문제가 제기되었고, 이를 해결하고자 표준화된 바이오디젤 품질 규격서가 마련되어졌다. 유럽에서 마련된 바이오디젤 규격에 의하면 올레인산 함량이 높은 기름이 바이오디젤 연료로 적합하며, 유채기름이 다른 유지작물의 기름에 비하여 바이오디젤 연료에 적합하다고 알려져 있다. 따라서 국내 유지작물의 바이오디젤 연료화를 위한 품질 개량과 생산량 증대를 위해 생명공학기술을 이용한 품종 개량에 관한 연구 전략에 대해 고찰하였다.

The road traffic noise has been increasing broader effects on urban areas as well as rural areas because of rapidly increasing traffic volume and newly-constructed roads. 10 sites in building development areas were selected and the noise levels were measured by the apartment floors and by the various block plans of apartment complex. The results showed that the highest traffic noise level was obtained at the 5 and 7 floors on the apartment floors. On the basis of 7 floor with the highest level, the correction coefficient obtained from noise reduction by each floor and measurement point was -5.54 dB(A)(1st floors), -0.96 dB(A)(3rd floors), -0.38 dB(A)(5th floors), 0.00 dB(A)(7th floors), -1.98 dB(A)(l0th floors), -3.10 dB(A)(13th floors), -3.45 dB(A)(15th floors). The level of road traffic noise in the arrangement construction of right angle was about 3.0 dB(A) at N-4 point and 2.1 dB(A) at N-6 point lower than that of a plan figure, respectively. The results suggested that application of correction coefficient obtained by the apartment floor and by the arrangement construction can be improved in road traffic noise.

This study was carried out in order to find out an effective machinery utilization strategy by conducting a survey on utilization and maintenance of agricultural machinery. The survey showed that the no. of utilization hours for power tiller in a year was 190.2hrs, 208.6hrs for tractor, 59.1hrs for rice transplanter, 74.0 hrs for combine, 44.6 cultivator and 254.4hrs for 4.4hrs for grain dryer. The period covered the time the machine was until it became unserviceable. The results are as follows: 10.0yrs for power tiller, 7.5yrs for tractor, 7.4yrs for rice transplanter and 5.4yrs for combine. This indicate that the actual period of use for power tiller and rice transplanter was longer than the expected period of duration years so there is a need for adjustment. The factors considered by the farmers for purchasing agricultural machine were: farm size(32%), machine operation (26.0%), performance(l4.0%) and post or after sales service(12.6%), according to the survey. It showed that repair cost rate in a year was classified into major agricultural machine; 4.8% for combine; 3.9% for tractor; 3.5% for rice transplanter; 2.0% for power tiller; 1.6% for grain dryer; and 1.2% for cultivator. The reasons for poor maintenance were insufficient after sales service(25%) and difficulty in buying parts(75%) because of the unavailability of parts in local shops(55%), imported models(30%) and outmoded model(15%).

Bacterial leaf pustule (BLP) caused by Xanthomonas axonopodis pv. glycines is a serious disease to make pustule and chlorotic haloes in soybean [Glycine max (L). Merr.]. While inheritance mode and map positions of the BLP resistance gene, rxp are known, no sequence information of the gene was reported. In this study, we made five near isogenic lines (NILs) from separate backcrosses (BCs) of BLP-susceptible Hwangkeumkong $\times$ BLP-resistant SS2-2 (HS) and BLP-susceptible Taekwangkong$\times$ SS2-2 (TS) through foreground and background selection based on the four-stage selection strategy. First, 15 BC individuals were selected through foreground selection using the simple sequence repeat (SSR) markers Satt486 and Satt372 flanking the rxp gene. Among them, 11 BC plants showed the BLP-resistant response. The HS and TS lines chosen in foreground selection were again screened by background selection using 118 and 90 SSR markers across all chromosomes, respectively. Eventually, five individuals showing greater than 90% recurrent parent genome content were selected in both HS and TS lines. These NILs will be a unique biological material to characterize the rxp gene.

Disease threatens plant growth and recognizing the type of disease is essential to making a remedy. In recent years, deep learning has witnessed a significant improvement for this task, however, a large volume of labeled images is one of the requirements to get decent performance. But annotated images are difficult and expensive to obtain in the agricultural field. Therefore, designing an efficient and effective strategy is one of the challenges in this area with few labeled data. Transfer learning, assuming taking knowledge from a source domain to a target domain, is borrowed to address this issue and observed comparable results. However, current transfer learning strategies can be regarded as a supervised method as it hypothesizes that there are many labeled images in a source domain. In contrast, unsupervised transfer learning, using only images in a source domain, gives more convenience as collecting images is much easier than annotating. In this paper, we leverage unsupervised transfer learning to perform plant disease recognition, by which we achieve a better performance than supervised transfer learning in many cases. Besides, a vision transformer with a bigger model capacity than convolution is utilized to have a better-pretrained feature space. With the vision transformer-based unsupervised transfer learning, we achieve better results than current works in two datasets. Especially, we obtain 97.3% accuracy with only 30 training images for each class in the Plant Village dataset. We hope that our work can encourage the community to pay attention to vision transformer-based unsupervised transfer learning in the agricultural field when with few labeled images.
