In this work, source reduction of poly ethylene terephthalate (PET) packaging are discussed as aspect of sustainability, such as reuse, refill and recycling through the various treatment methods and historical studies for municipal solid waste (MSW) disposal. Since PET has good chemical, physical and mechanical properties, and provides good oxygen and carbon dioxide barrier properties, PET is one of the most widely used thermoplastic polyester in the U.S. and around the world. As the demand for non-renewable PET is increasing, several approaches have been developed to meet economical feasibility and environmental responsibility without degrading material performance. Several companies, such as Coca-Cola Co., Easterform Packaging Co. and Kraft, have tried to develop lightweight PET bottle, and some of lightweight PET bottles are already commercialized. Reuse and refilling for PET container is well developed in Europe, such as Denmark, German and Netherland by supportive legislation and policies. Recycling process is the best way to economically reduce PET waste. In consequence, advanced technique and further development must be provided due to increasing PET packaging waste.

의약품을 자동 포장하는 시스템에서는 캐니스터(Canister)에 해당 약을 정확히 보충할 수 있는 해당 약통과 캐니스터와의 일치 여부를 판단하는 정합 알고리즘이 필수적이다. 본 논문에서는 약화사고 방지를 위해 많은 종류의 약통을 분류하기 위한 분류 성능뿐만 아니라 실시간으로 처리할 수 있는 상 하 계층으로 구성된 계층적 신경회로망을 제안한다. 먼저 약통 정보를 나타내는 라벨 영상으로부터 다수의 저 차원 특징 벡터를 추출한다. 추출된 특징 벡터를 사용하여 하위계층의 다층 퍼셉트론(MLP, Multi-layer Perceptron) 신경회로망을 학습한다. 다음으로 학습된 MLP의 중간층 출력을 입력으로 사용하여 상위계층의 MLP를 학습한다. 100개의 약통에 대해 좌우 30도까지 회전한 영상에 대해 제안한 계층적 신경회로망의 분류 성능 시험과 실시간 연산처리 성능의 우수함을 보였다.

Background: This study examined the public's perceptions of repeat dispensing as one of the measures to reduce the harmful effects of long-term prescriptions in Korea. Methods: From January 11 to 25, 2021, an online survey was conducted for adults using convenience sampling. A self-developed questionnaire was used. Results: There were 310 respondents, of which 228 (73.5%) preferred repeat dispensing. When considering the additional fee payment, 188 (60.6%) preferred repeat dispensing, and 54 (67.5%) out of a total of 80 chronic disease patients preferred it. It was confirmed that there was a difference in the willingness to repeat dispensing considering the additional cost depending on whether the patient had a chronic disease and the distance from home to the nearest pharmacy. As a result of subgroup analysis for patients with chronic diseases, frequency of outpatient visit, number of prescription days, method of packaging pharmaceuticals, and distance from home to the nearest pharmacy were identified as variables that could well predict the willingness to repeat dispensing considering paying additional fees. The preference for repeat dispensing may vary depending on conditions such as additional cost range, frequency and period of prescription use, disease and patient characteristics, so a careful approach is necessary. Conclusion: It is necessary for the government to consider the introduction of repeat dispensing with interest in the public demand.
