In this research, we reappraise saemaul project which is a leading role of rural development in a present perspectives and deduct social and political implications for rural development. For deducting problems and implications, related documents and previous researches are reviewed. Administration statistics are also gathered and analyzed for monitoring detailed projects propulsion progress and results. Samaul project is reappraised based on previous researches such as rural development, regional agricultural production system improvement, agricultural distribution system improvement, leader breeding, income improvement, and governance. Saemaul project has basically positive characteristics because of decreasing growth gap of urban and rural area by empowering cooperation of rural residents, instilling leadership, making village fund, constricting networks of government and urban area for administrative and financial assistant. In conclusion, there are implications that continues interests of most powerful sovereignty and comprehensive assistant of government are needed for overcome agricultural and rural crisis. Saemaulundong is a united and systematic approach in village level. In south korea where most of farms are small size, village or regional level assistants started in saemaulundong are still needed. In regional development, we can infer that will and ability development of participated residents are most basic and important factors for successful project propulsion in saemaul project.

Zoysiagrass (Zoysia japonica Steud.), also called Korean or Japanese lawngrass, is the most popular warm-season turfgrass in Korea and is widely used for home lawns, parks, roadsides, golf courses and athletic fields. Its use is rapidly expanding in Korea and the other countries, due to its excellent characteristics which include tolerance to heat, drought and salinity. As the utilization area of this turfgrass increases, there is an increase in the demand for improved cultivars with disease and insect tolerance or with herbicide-tolerance or with extended greening periods. Conventional breeding methods have been used to improve the traits described above with limited success. However, with the advances in biotechnology, genetic transformation can be utilized for turfgrass improvement. In this paper, we review recent progress in biotechnological improvement of zoysiagrass and discuss future molecular breeding of this species.

Immune checkpoint inhibition has been established as a new treatment option for various types of carcinoma, and many clinical trials are being actively conducted as a treatment for advanced or metastatic gastric cancer, either as a monotherapy with an immune checkpoint inhibitor or as a combination therapy with standard chemotherapy. In the CheckMate-649 clinical trial to confirm the efficacy of the combination of nivolumab and chemotherapy (FP) in advanced gastric cancer and gastroesophageal junction cancer, nivolumab group showed improvement in overall survival in programmed death ligand 1-positive cancer patients compared with placebo group. Also, the combination therapy of pembrolizumab, trastuzumab and chemotherapy (FP) in first-line treatment was tested through the KEYNOTE-811 trial. The pembrolizumab group showed 22.7% of improvement in objective response rate compared with placebo group. Accordingly, the combination of nivolumab/pembrolizumab with standard chemotherapy was approved for the first-line treatment. In KEYNOTE-059 trials for patients with progressive disease after at least two lines of chemotherapy, pembrolizumab monotherapy showed improvement in objective response rate and overall survival, and the use of pembrolizumab was approved for the third-line or more treatment. In this article, we review the result of clinical trials related to immune checkpoint inhibitors that have been recently introduced in the treatment of gastric cancer.

An emphasized analysis and reviews on the progress of pesticide managements for the past 10 years through the statistics in Korea are summarized in this continued studies in connection with the fundmental aspects and direction of advanced pesticide industry and improved plantprotection policies for 1980's. Remarkable development and changes are observed in the plant species and varieties, plantation practices and production techniques as well as pest infestations and controls in the last decade, but no normal achievement and operations are recognised on the pesticide management and marketing system especially. Realistic plant protection adminstration and pesticide regulations in accordance to the industrial modernization and pest management advancement must be adjusted in accordance with national economic progress and desirable agricultural structure for 1980's. Special considerations are stated on the strengthening of research and inspection program for the quality products and control with the efficacy and safety use of pesticides. More serious attentions are noted on the over production and flooded stocks under struggled market demands and sales competitions with lethal financial difficulties by producers. Through the status analyzed for the last decade, the integrated past management and cooperative basic control pattern under positive self-forecasting system by farmers are also urged for the effective and economic pest control measures. The problems and solutions discussed here ell the advanced pesticide management as well as the cooperation on the self-ordered quality control and market managing systems in 1980's as it is a desired projection for the further improvement. Most of outstanding and necessary statistics and data in the past decade are also summarized here for references in connection with the previous report.

Iron and nitrogen codoped carbon (Fe-N/C) catalysts have emerged as one of the most promising replacements for state-of-the-art platinum-based electrocatalysts for oxygen reduction reaction (ORR) in polymer electrolyte fuel cells. During the last decade, significant progress has been achieved in Fe-N/C catalysts in terms of ORR activity improvement and active site identification. In this review, we focus on recent efforts towards advancing our understanding of the structure of active sites in Fe-N/C catalysts. We summarize the spectroscopic and electrochemical methods that are used to analyze active site structure in Fe-N/C catalysts, and the relationship between active site structure and ORR activity in these catalysts. We provide an overview of recently reported synthetic strategies that can generate active sites in Fe-N/C catalysts preferentially. We then discuss newly suggested active sites in Fe-N/C catalysts. Finally, we conclude this review with a brief future outlook.
