“…This paper first establishes the distribution model between different categories of vegetable commodities as well as different individual products. Considering that the sales of vegetables are related to the seasons, the average monthly sales and average daily sales of each category of vegetables are obtained by using the processing of the data, and then the data of each single product are obtained according to the same principle; for the degree of correlation between different categories [3], the Q-Q diagram is used to determine that the data do not conform to the positive distribution, so the Spearman's correlation coefficient is used to analyze and to draw heat maps; and for the correlation degree among the different single products As there are too many types of single products, grey correlation and clustering analysis are considered to deal with the degree of correlation between them, and the criterion of clustering is to take their four-year average daily sales, transform it into the overall value, and then through low-dimensional visualization, after initially judging that it can be divided into a few categories, clustering is performed on the single products. In order to help merchants determine the total daily replenishment and pricing strategy for the coming week, the seasonal ARMA model is considered to be used to fit the curves of sales and cost margin of each image category using SVR; finally, a single-objective optimization model with the goal of maximizing the revenue of the superstore is established, which helps merchants determine the total daily replenishment and pricing strategy for the coming week [4].…”

This paper explores the importance of pricing and replenishment issues of vegetable items for merchant operations. First, data related to vegetable stocking were systematically collected to assess the correlation between different categories. Through Q-Q plot analysis, it was determined that the data did not conform to a normal distribution, so the Spearman correlation coefficient was chosen for further quantitative analysis. Considering the large number of individual vegetable categories, in order to deal with the correlation between different individual items, a hierarchical clustering method was introduced in this paper, which classified them into three categories: low volume, medium volume and high volume. In order to predict the future vegetable intake, this study adopted the seasonal ARMA model and applied the Pearson's correlation coefficient for correlation analysis by combining the cost utilization rate as well as the total sales volume. In addition, the relationship between sales and cost margin was fitted with the help of support vector machine. Finally, this study constructs a single optimization model with the objective of maximizing the revenue of the superstore. The innovation of this paper is the combination of various statistical and machine learning methods in order to solve the pricing and replenishment problem of vegetable items, aiming to improve the efficiency of merchant operations.

“…Cereal grain milling fractions are categorized as processed foods in Codex but are categorized as cereal grains in Korea. Particularly, dried fruits, vegetables, and herbs are categorized as processed foods in Codex, whereas they are categorized as raw ingredients or processed foods according to the processing methods in Korea (Lee 2018 ; 2019a ; 2019b ).…”

Korea’s overall food safety management policies reflect the Codex guidelines in terms of risk analysis and standards. Korea’s food safety management plan, which is established every 3 years, includes the pre-emptive management of risk factors and provides food safety information on the basis of scientific evidence. Since officially joining Codex as a member country in 1971, Korea has led the establishment of six Codex standards, including those for Kimchi and Gochujang . Moreover, Korea’s food standards are harmonized with Codex’s risk assessment system. This review aims to examine the current status and trends of Codex and to summarize and compare the food safety management systems and food standards between Korea and Codex.

Flowering and Inflorescence Development Characteristics of Korean Mint Affected by Different Photoperiods

2022

The Korean mint (Agastache rugosa Kuntze) is used as a leaf vegetable. Therefore, it is important to improve the quality and quantity of leaves by maintaining vegetative growth. When the development of a plant is switched from vegetative to reproductive growth, leaf development may be lowered, leading to a decrease in marketability. Therefore, this study was conducted to investigate the effect of the photoperiod on the flowering characteristics and inflorescence development of the Korean mint to select an appropriate photoperiod for leaf production. The seeds were sown in 105-cell trays on 29 November 2021, and planted in each pot on 27 December 2021, when four main leaves appeared. After planting, the light/dark period was adjusted to 10/14hrs, 12/12hrs, 14/10hrs, 16/8hrs. After 19 days of planting, the first flowering occurred in 10/14hrs, which had a short photoperiod, and the 12/12hrs had 20 days for flowering, and other treatments had 21 days. In addition, it was confirmed that the Korean mint has the characteristics of facultative quantitative short-day plant, through the increase in the development of inflorescences as the light period is shorter than the dark period. As for the growth of Korean mint, the longer the photoperiod, the higher values were shown with leaf length, number of leaves, fresh weight, dry weight, and leaf area of the shoot. Therefore, it is considered that 14 h or more light period is suitable for increasing the productivity of Korean mint as a leafy vegetable.
