  • The purpose of this study is to compare the differences in the subjective quality of life (QoL) perceived by residents in different settlement spaces such as urban vs. rural and Seoul Capital Area (SCA) vs. Non-Capital Area (NCA). Using the data of the 'Quality of Life Satisfaction Survey for Balanced Development' conducted nationwide by the Presidential Committee for Balanced National Development in 2018, a propensity score matching method was introduced to compare the differences between the types of settlement spaces. The results show that no significant difference is found between all the types in satisfaction with local life, and in the case of happiness, rural residents show a higher level than those living in cities. Looking at the quality of life by QoL domain, the QoL of urban residents in SCA is generally the highest in the basic living environment, medical care, and culture/leisure domains, while the QoL of rural residents in the job/income, environment, community, and welfare domains is higher than that of residents of SCA and NCA cities. Interestingly, in no domains NCA cities show their relative strength. These results show the value of rural areas in the face of increasingly prevailing urbanization trends, and suggests that the value of rural areas must be strengthened for rural development. It is necessary to pursue policy efforts such as rural regeneration based on spatial planning in order to respond to the disorganized development that damages the value of the rural environment and landscape and to harmoniously maintain and develop the rural settlement.

  • The six barnyardgrass [Echinochloa oryzicola (vasing.) Vasing.] and seventeen barnyardgrass [Echinochloa crus-gadli (L.) Beauv.] accessions, which were collected national widely in 1986 and selected two times through 1987. To study different growth response due to herbicide, pyrazolate, bifenox, quinclorac, the experiment was conducted with herbicide agar culture without nutrients, 1. Albinistic discoloration due to pyrazolate was more sensitive in E, crus-galli than E. oryzicola and among barnyardgrass accessions, Kumi, Ichon-A, Ichon-B, Boun-B and Kwangju-B were rather susceptible than Gyongju, Ansong, Boun-A, Jongju-A and Kwangju-A. 2. Twisting and growth retardation due to bifenox was less sensitive in E. oryzicola with less intra-specific variations than in E. crus-galli. Among E. crus-galli accessions, Boun-B, Ansong, Ichon-A, Ichon-B, Wonju and Kwangju-B were particulary susceptible, and Jinyang, Jongju-B, Jongju-A, Daejon, Kurye and Kwangju-A were tolerant as much as E. oryzicola. 3. Growth retardation and withering to dead due to quinclorac was more sensitive in E. oryzicola with less intra-specific variations than in E. crus-galli. Among accessions of E. curs-galli, Boun-A, Iri, Jongju-A, Jongju-B, Kwangju-A and Kwangju-B were rather similar suseptible to E, oryzicola than kimhae, Gyongju, Kumi, Wonju, Ichon-A, Ichon-B and Ansong. 4. Most accession of E. oryzicola was tolerant to both pyrazolate and bifenox, while susceptible to quinclorac. Among other accessions of E. crus-galli, Kurye, Kimhae, and Daejon were tolerant to all experimented herbicides, and Iri, Jongju-A, Jongju-B, and Kwangju-A were only tolerant to both pyrazolate and bifenox, while Kumi, Wonju, Ichon-A, Ichon-B, Boun-B and Kwangju-B were only tolerant to quinclorac.
