골목상권은 상권 경쟁력 확보와 상권 내 점포의 안정적 운영 측면에서 중요한 공간적 영역으로 인식되어 왔고, 코로나 이후 상권 측면에서도 골목상권은 중요한 연구 대상으로 제기되고 있다. 지금까지 골목상권 연구는 서울시와 같은 대도시 골목상권 을 중심으로 진행되어 왔다. 이에 본 연구는 청주시를 사례로 소상공인 개별 데이터와 GIS 기법을 활용하여 중소도시에 적합한 골목상권 영역 설정 방법을 제안하고, 이를 토대로 골목상권 유형을 분류하고 주요 특성을 살펴보고자 하였다. 골목상권 영역 설정은 데이터 전처리 과정을 거쳐, 생활밀착형 업종 점포를 추출하고 도로명주소 내 ‘길’ 단위 점포를 추출하여 골목상권 영역을 설정하였다. 골목상권 유형은 개폐업률에 의해 성장형-순환형-정체형-쇠퇴형으로 분류하고, 네 유형의 골목상권 분포를 지도화하 고 상권별 주요 특성을 살펴보았다. 본 연구에서 제안한 골목상권 영역 설정 방법과 유형 분류는 앞으로 세밀한 골목상권의 이해와 공간 단위에서의 골목상권 변화에 활용되기를 기대한다. 또한 본 연구의 성과는 상권의 이해와 변화 예측을 넘어 골목상권 활성화를 위한 정책 수립의 출발점이 될 수 있다.

This study was conducted at the National Institute of Animal Science (NIAS) from 2010 to 2017 to develop a late-maturing variety with high productivity for cultivation in the southern region of South Korea. The new variety of Italian ryegrass, ‘IR901’, was a late-maturing variety, and its heading date was 22 May, 17 days later than that of the control variety ‘Kowinearly’. ‘IR901’ had a flag leaf width of 11.2 mm, flag leaf length of 31.8 cm, and plant length of 103 cm on its heading date. The combined average dry matter yield of ‘IR901’ in all three adaptability evaluation regions (Cheonan, Pyeongchang and Haenam) was 7,747 kg/ha, which was similar to that of the ‘Kowinearly’ variety (7,734 kg/ ha). However, the average dry matter yield over three years in Cheonan and Pyeongchang was 82% and 96%, respectively, compared to that of the control, which was most likely because of the poor cold tolerance of ‘IR901’. By contrast, in Haenam, in the southern region, the average dry matter yield of ‘IR901’ was 19% higher than that of the ‘Kowinearly’ variety. The proportions of crude protein (CP), total digestible nutrients (TDN), acid detergent fiber (ADF), and neutral detergent fiber (NDF) in ‘IR901’ were 8.6%, 59.7%, 36.9%, and 54.8%, respectively; the proportions were 0.2% lower, the same, the same, and 2.5% lower than those in the ‘Kowinearly’ variety. The determined in vitro dry matter digestibility (IVDMD) of ‘IR901’ was 72.2% higher than that of ‘Kowinearly’ (67.2). In general, of the two varieties, the forage quality of ‘IR901’ was marginally superior to that of ‘Kowinearly’.

In Korea livestock farms breeding cattle have been suffering from re-emerging problems of Brucella (B.) abortus infection while steady decline of bovine brucellosis. Therefore, this study underscored the identification and association of etiological agent of brucellosis in cattle in South Korea. The incidence of brucellosis in cattle was analyzed by bacteriological and molecular methods in 187 brucellosis-suspicious farms of 11 regions between 2018 and 2020. Brucella isolates from various specimens were identified by Brucella-specific multiplex PCR. Epidemiological data were collected by local official veterinarians through history taking from farmers and animal data systems. In 230 of 560 cattle (40.9%) and 94 of 187 farms (50.3%), a total of 313 B. abortus were isolated from various specimens, the majority of isolates were from supramammary lymph node (41%). In epidemiological findings, the majority of positive cases were mainly caused by resurgence (43.7%) and unknown (37.2%). Of 94 positive cases isolated B. abortus, abortion in cattle infected by B. abortus occurred in 51 farms (54.3%) where led to resurgence in 30 farms and environmental survival of B. abortus in 9 farms. Consequently, these findings revealed the existence of etiological agent of bovine brucellosis in Korea, which still occurred at low levels in distinct regions where are allowed to call for persistent biosecurity. Thus, we highlight that brucellosis in Korea needs to take more effective control strategies with potential evidence. Moreover it is ultimately important to maintain a constant monitoring for eradication of brucellosis.
