飲食店向け不動産物件の賃料は,不動産会社のベテラン営業職員が培ってきた経験や勘といった暗黙知に基づいて決定されている.賃料の決定要因としては,物件固有の情報である静的情報,物件周辺の情報である動的情報,物件の特徴などを含む潜在的情報が挙げられている.潜在的情報は,ベテラン営業職員による指標化が難しいとされる情報である.本研究では潜在的情報として,物件に付与されているキャッチコピーを用いる手法を提案する.キャッチコピーはDoc2Vec によりベクトル表現に変換し,ノイズを除去するため,品詞の選別を行なった.その結果,品詞の選別を行うことで推定精度が向上し,重回帰分析を用いた場合に,決定係数が0.611 と最も高い値が得られた.

The COVID-19 Pandemic is a global problem, and to prevent the spread of the infections, it is crucial not only to develop vaccines and therapeutic medications but also to encourage people to change their behavior. Behavioral change to prevent the spread of infectious diseases has required people to give up many activities, especially pleasures outside the home. However, it is hoped that if most people behave cooperatively, individuals’ selfish pursuit of pleasure will have little effect on the spread of infection. This conflict between benefits for individuals and those for the community as a whole can be considered a social dilemma. Clarifying the factors that define people’s behavior during epidemics is essential for designing social systems after the COVID-19 Pandemic is declared over. Here, we analyze the determinants of people’s behavior in the framework of a social dilemma by conducting a two-wave panel survey in 2020 and 2021. The results show that in the first wave, psychological attitudes that affect prosocial behavior, such as reciprocity, positively affect prosocial behavior. However, in the second wave, these effects disappear, and other factors define people’s behavior. Continuous analysis of the factors determining people’s behavior under drastically changing circumstances can provide information for planning measures to promote desirable behavioral changes.

A 79-year-old man with underlying alcoholic liver cirrhosis presented with complaints of a fever, abdominal pain, and difficulty walking. A diagnostic work-up revealed liver atrophy and chylous ascites, and spontaneous bacterial peritonitis (SBP) was diagnosed based on the cell and neutrophil counts. The Burkholderia cepacia complex (Bcc) was detected on blood and ascitic fluid cultures. Although broad-spectrum antibiotic therapy was initiated, the infection was difficult to control, and the patient died of multiple organ failure. Bcc is often multidrug-resistant and difficult to treat. SBP caused by Bcc has been rarely reported and may have a serious course, thus necessitating caution.
