Abstract: Proposed is an apparatus for measuring capsaicin in chili peppers. More particularly, proposed are an apparatus and a method for measuring capsaicin in chili peppers, the apparatus and the method being capable of measuring the capsaicin content of chili peppers simply and precisely. The apparatus includes: a first electrochemical measuring cell and a second electrochemical measuring cell into each of which a capsaicin extract is injected; a multiplexer electrically connected to a selected one of the first and second electrochemical measuring cells; a potentiostat applying voltage to the first or second electrochemical measuring cell and measuring an oxidation current value; and a controller controlling the potentiostat and the multiplexer to sequentially electrically connect the potentiostat to each of the first and second electrochemical measuring cells and measuring a first capsaicin content and a second capsaicin content on the basis of the oxidation current value as a function of applied voltage.

Abstract: The present invention relates to a light irradiation apparatus including: a body part, base parts coupled to the body part, light irradiators coupled to the corresponding base part to irradiate light on a user's body, and position adjustors for adjusting the light irradiators in position and having one or more actuators controlled by a computing device, wherein the one or more actuators adjust the light irradiators in position so that the positions of the light irradiators correspond to the user's body on which the light is irradiated.

Abstract: A remote consulting service apparatus may include: a first image collection unit configured to capture a first image displayed on a screen of a customer terminal; a first display unit on which the first image collected from the first image collection unit is displayed; and a control unit configured to perform control such that information input from a consultant is displayed on the first image displayed on the first display unit. The remote consulting service apparatus may further include a second image collection unit configured to capture a face image of the customer.

Abstract: A recommendation apparatus separately extracts a positive graph and a negative graph representing the user's preference and non-preference for each item from the bipartite graph representing the relationship between users and items obtained using evaluation data, and vectorizes a plurality of nodes corresponding to users and items based on each of the extracted positive graph and negative graph and embeds them in a common virtual embedding space to recommend items that the user would prefer by considering not only preferences but also non-preferences of similar users for items.
