This paper aims to examine the effects of non-tariff measures (NTMs) on the world trade in potatoes. A structural gravity trade model is estimated with a panel dataset over the 2007~2018 periods and correction for selection bias is performed by adopting the Heckman two stage and the Poisson Pseudo-Maximum Likelihood estimators. Estimation results show positive estimates for a dummy and the cumulative frequency of NTM variables, providing the best evidence for the existence of the trade facilitating role played by the NTMs. These findings suggest the existing NTMs of potato trade helps ease consumers' information asymmetry and other external effects that are actually improving food safety and legal trade environments.

Movie poster, which have been a part of the history of film, play a significant role in advertising movies. In recent times, movie posters have also become a collectible objects and media provokes collectors to bring them back to the theater again, especially ever since the Covid-19 pandemic broke. Given this, it is increasingly important that the re-released and special format movie posters need to have a more appealing image to arouse the desire of collectors and even those interested in the movie. In this article, newly released and re-released movie posters a type of commercial -advertising photography are first analyzed based on semiotics theory to understand what features are important in making movie posters that can evoke the desire to collect. Based on the analysis, it is concluded that using an objet is an effective way to convey the content of movie and create a more tempting image. Therefore, a sample image of re-released movie poster that uses an objet is produced based on the analysis.

The Ministry of Agriculture, Food and Rural Affairs, Hanwoo Association and Nonghyup have discussed proactive reduction measures for cows in response to concerns about an oversupply of hanwoo to ensure supply stability. This study aims to empirically analyze whether the cow fattening support program is being implemented in line with its objectives. Based on the analysis of beef traceability data, the slaughter age of participating cows was reduced by 7.6 to 14.7 months compared to non-participating cows. And heifer was reduced 1.5 months in their slaughter age. In case of parity, participating cows showed a reduction of 1.4 compared to non-participating cows. Through the SUR model, an analysis was conducted to examine the effect of the cow fattening support program on the suppression of calf production numbers. The analysis results showed that the calf production numbers are positively influenced by the number of fertile cow and the quantity of semen sales. Furthermore, it is estimated that calf production decreased as the fat index increased, and during the period when the cow fattening support program was implemented, an average monthly suppression of 3,558 calves was observed.

1) 수급 동향 ∙ (콩) 2021양곡연도 수확기(11~1월) 콩 가격은 작황 악화 등으로 생산량이 전년보다 감소하였고, 코로나19로 가정 내 소비는 증가해 전년 대비 16.1% 상승하였다. ∙ (감자) 2020년 감자가격은 모든 작형의 생산량이 감소하며 전년 대비 상승하였다. 그러나 노지 봄감자와 고랭지감자 등의 품위가 저조하고, 수요도 부진한 영향으로 가격 상승폭은 크지 않았다. 2) 단기 전망 ∙ (콩) 2021양곡년도 단경기(8~10월) 콩 가격은 작황 악화에 따른 시장공급가능물량 감소와 코로나19로 인한 가정 내 소비 증가로 수확기 대비 강보합세를 나타낼 것으로 전망된다. 수확기 가격 상승으로 밭콩 재배의향면적은 증가하나, 논타작물재배지원사업 종료와 쌀 가격 강세 영향 등으로 논콩은 감소해 전체 재배의향면적은 전년과 비슷할 것으로 조사되었다. ∙ (감자) 2021년 상반기 감자가격은 고랭지감자 생산량 감소 등으로 저장물량이 감소하였고, 시설감자 출하비중 확대로 전년 대비 가격이 상승할 것으로 전망된다. 시설 봄감자 재배면적은 경합작물 가격 상승 등으로 전년 대비 2.4% 감소할 전망이고, 노지 봄감자 재배의향면적도 전년도 농가 조수입 감소 등의 영향으로 전년 대비 1.8% 감소할 것으로 조사되었다. 3) 중장기 전망 ∙ (콩) 콩 재배면적은 논타작물재배지원사업 종료, 쌀값 상승 등의 영향으로 벼 재배로 회귀하는 경우가 많아 감소 추세가 이어질 것으로 전망된다. 생산성 향상 등으로 자급률이 상승 추세를 보이겠으나, 상승폭은 크지 않을 전망이다. ∙ (감자) 가공식품 소비가 증대되는 식품 소비트렌드가 가속화되는 가운데, 원물 형태의 소비비중이 높은 감자 소비는 점차 감소하며 재배면적이 향후 10년간 연평균 1.0% 감소할 것으로 전망된다.

Objective To explore whether the Mini-Mental State Examination (MMSE) and Montreal Cognitive Assessment (MoCA) can be used to screen for dementia or mild cognitive impairment (MCI) in less educated patients with Parkinson’s disease (PD). Methods We reviewed the medical records of PD patients who had taken the Korean MMSE (K-MMSE), Korean MoCA (KMoCA), and comprehensive neuropsychological tests. Predictive values of the K-MMSE and K-MoCA for dementia or MCI were analyzed in groups divided by educational level. Results The discriminative powers of the K-MMSE and K-MoCA were excellent [area under the curve (AUC) 0.86–0.97] for detecting dementia but not for detecting MCI (AUC 0.64–0.85). The optimal screening cutoff values of both tests increased with educational level for dementia (K-MMSE < 15 for illiterate, < 20 for 0.5–3 years of education, < 23 for 4–6 years, < 25 for 7–9 years, and < 26 for 10 years or more; K-MoCA < 7 for illiterate, < 13 for 0.5–3 years, < 16 for 4–6 years, < 19 for 7–9 years, < 20 for 10 years or more) and MCI (K-MMSE < 19 for illiterate, < 26 for 0.5–3 years, < 27 for 4–6 years, < 28 for 7–9 years, and < 29 for 10 years or more; K-MoCA < 13 for illiterate, < 21 for 0.5–3 years, < 23 for 4–6 years, < 25 for 7–9 years, < 26 for 10 years or more). Conclusion Both MMSE and MoCA can be used to screen for dementia in patients with PD, regardless of educational level; however, neither test is sufficient to discriminate MCI from normal cognition without additional information.
