In the global manufacturing industry, digital transformation is emerging as an important issue for companies to improve productivity and strengthen industrial competitiveness. The government and shipbuilding companies drive research and development to attain advanced technologies through digital transformation for shipbuilding & offshore plants, one of Korea's representative manufacturing industries. Therefore, the digital transformation of the shipbuilding & offshore plant industry was defined using an input-output analysis model, and the economic interrelationships of industries linked to the digital transformation of the shipbuilding & offshore plant industry were analyzed. According to the analysis, the shipbuilding & offshore plant industry ranks second among all 34 industries regarding the forward linkage effect. The backward linkage effect was ranked 27th, making it a mid-demand industry with a robust forward linkage effect. In addition, the production-induced effect was 0.455, the value-added-induced effect was 0.174, and the employment-induced effect was 1.779 people per billion won. The contribution of this study is that it will provide the basis for establishing policies necessary to strengthen the competitiveness of the shipbuilding & offshore plant industry. Also, it will help analyze the economic effects of digital transformation in other manufacturing industries.

국립생태원에서는 2016~17년에 걸쳐 한반도의 남부지역에 해당되는 충청ꞏ전라, 경상 지역에서 외래생물 전국 서식실태조사를 수행하였으며, 그 중 외래곤충 현황에 대한 결과이다. 2016년 충청ꞏ전라권역 65개 시ꞏ군에서 총 8목 20과 28종의 외래곤충이 조사되었으며, 그 중 2종의 미기록종(Hindoloides bipunctatus, Salurnis marginella)이 확인되었다. 해당 권역에 분포하는 외래곤충 중 갈색날개매미충은 48개 시ꞏ군으로 가장 많은 지역에서 서식이 확인되었고, 다음으로 꽃매미(41), 등검은말벌(35), 버즘나무방패벌레, 해바라기방패벌레(30), 미국선녀벌레(27) 순이 었다. 2017년 경상권역 43개 시ꞏ군에서 총 6목 24과 32종의 외래곤충이 조사되었으며, 그 중 1종의 미기록종(Dentatissus damnosus)과 2종의 미접종(뾰족부전나비, 무늬박이제비나비)이 확인되었다. 해당 권역에 분포하는 외래곤충 중 남방노랑나비가 37개 시ꞏ군으로 가장 많은 지역에서 서식이 확인되었고, 다음으로 꽃매미(36), 해바라기방패벌레(35), 등검은말벌(31), 돼지풀잎벌레(30) 순이었다. 남부지역 총 133개 시ꞏ군에서 꽃매미가 가장 많은 지역(77)에서 서식이 확인되었으며, 다음으로 갈색날개매미충(70), 등검은말벌(66), 해바라기방패벌레(65) 순이었다.

Potato virus Y (PVY) and potato leafroll virus (PLRV) are among the most damaging potato viruses and prevalent in most potato growing areas. In this study, cryopreservation was used to eradicate PVY and PLRV using two cryogenic methods. Potato shoot tips proliferated in vitro were cryopreserved through droplet-vitrification and encapsulation-vitrification using plant vitrification solution 2 (PVS2; 30% glycerol + 15% dimethyl sulfoxide + 15.0% ethylene glycol + 13.7% sucrose) and modified PVS2. Both cryogenic procedures produced similar rates of survival and regrowth, which were lower than those from shoot tip culture alone. The health status of plantlets regenerated from shoot tip culture alone and cryopreservation was checked by reverse transcription-polymerase chain reaction. The frequency of virus-free plants regenerated directly from highly proliferating shoot tips reached 42.3% and 48.6% for PVY and PLRV, respectively. In comparison, the frequency of PVY and PLRV eradication after cryopreservation was 91.3~99.7% following shoot-tip culture. The highest cryopreserved shoot tip regeneration rate was observed when shoot tips were 1.0~1.5 mm in length, but virus eradication rates were very similar (96.4~99.7%), regardless of shoot tip size. This efficient cryotherapy protocol developed to eliminate viruses can also be used to prepare potato material for safe long-term preservation and the production of virus-free plants.
