Phytophthora root and stem rot (PRR), caused by Phytophthora sojae, can occur at any growth stage under poorly drained and humid conditions. The expansion of soybean cultivation in South Korean paddy fields has increased the frequency of PRR outbreaks. This study aimed to identify four P. sojae isolates newly collected from domestic fields and evaluate race-specific resistance using the hypocotyl inoculation technique. The four isolates exhibited various pathotypes, with GJ3053 exhibiting the highest virulence complexity. Two isolates, GJ3053 and AD3617, were screened from 205 soybeans, and 182 and 190 genotypes (88.8 and 92.7%, respectively) were susceptible to each isolate. Among these accessions, five genotypes resistant to both isolates were selected. These promising genotypes are candidates for the development of resistant soybean cultivars that can effectively control PRR through gene stacking.

Purpose: To establish the building guidelines and to analyze the function of Regional Public Hospitals, the survey was conducted primarily on the current status focusing on the location and relationship of the department, area composition ratio, area per bed, and area per operating room. Methods: The research methods of this paper are as follows. 1) A literature survey on the function of the operating and related departments, 2) A drawing analysis for spatial composition and net area calculation. Results: The area of the Operation Department in the Regional Public Hospitals with 200 to 300 beds are as follows. Area ratio: 3.35%, area per Bed: 2.53㎡/bed, the number of beds per operating room: 64.37bed, area per operating room: 146.46㎡/n, area per operating room by plan type: integration corridor 133.84㎡/n, separation corridor 184.82㎡/n. Implications: This paper analyzed data on the current state of Operation Departments for setting up the function and role for the Regional Public Hospital. In the future, it is also required to provide size that takes into account user behavior and the user's psychological aspect in order to suggest appropriate area.

Protein is a major nutrient of food and has long been studied for nutritional and utility value. Among them, rice protein is attracting attention because of its hypoallergenic characteristics and nutritional value. Mutant DM225 with increased protein content was selected by EMS treatment on the weed rice Dharial. QTL analysis of Protein content was carried out using BC₂F₂ populations derived from a cross between "Hanareum2" as a recurrent parent and "DM225" as a donor parent. The protein content of populations was between 5~11%, with an average of 7.7%. To identify QTLs related to Protein content, 117 KASP markers(polymorphic ratio: 15%) showing polymorphisms between the parents were genotyped for the BC₂F₂ population. One QTL was detected between markers SK07 06 and SK07_10 on chromosome 7(LOD: 28.1). This QTL explained 71.4% of the phenotypic variance for Protein content. This QTL will be useful for protein-related rice breeding program.
