Background : Senna tora L. is an herbaceous annual foetid herb. There were many components s uch as emodine, chrysophanol, aloe-emodine, physcion, rhein, chrysophanic acid, obtusin, aurantio-obtusin, anthraquinone compounds. The seeds and leaves are used to treat skin disease and its see ds can be utilized as a laxative, as well as to good for the eyes. This experiment was focused on the storage characteristics for searching better condition. That's why it is very useful for making oriental medicine. It is needed for Good Agricultural Practices (GAP) certification. It is one of ce rtification condition. Many medicinal plants have almost no their storage condition for GAP. Methods and Results : There are two kinds of treatment for storage test. One is temperature. The other is time period. The temperature treatments are room temperature and 4℃. Time of storage periods are four parts. The first time period for storage is zero month. The Second is until three month. and the third is until six month. The fourth is until nine month. We used polyethylene for packing materials. We investigated moisture, ash, bacteria, Escherichia coli, Staphylococcus aureus, mold and chromaticity by them. The value of moisture and ash are under standard of permission as 7.8 and 5.1 respectively. There were almost no significance about test microorganism in the storage temperature condition. There were statistical significance on the bacteria and mold without Escherichia coli, Staphylococcus aureus according to storage period. In terms of stroage temperature and period interaction, there was statistical significance on the Escherichia coli. In addition, the mycotoxin (aflatoxin) was analyzed for nine month storage Senna tora L. The total aflatoxin value were 3.307 ppb and 3.334 ppb in storage temperature and period respectively Conclusion : About the characteristics of Senna tora L. in accordance with the storage treatments, there were differences along with time period of storage about the bacteria and mold. There was no aflatoxin until nine month storage.

Background : Schizonepeta tenuifolia Kitagawa is a herbaceous plant affiliated to labiate. It ha s many oil components which has antimicrobial activity for health with limonene, menthone, p ulegone, piperitenone, schizonepetoside A, schizonepetoside C, spatulenol. The planting area of which is comparatively small than other medicine crop as 5 ha area and 15MT in the nation. This experiment was focused on the storage characteristics for searching better condition. It is very useful for making oriental medicine. It is needed for Good Agricultural Practices (GAP) certification. It is one of certification condition for farmers. Many medicinal plants have almos t been no their storage condition for GAP. Methods and Results : This experiment was carried out to conform optimal condition for S. tenuifolia Kitagawa. There were two kinds of treatment for storage test. One is temperature. The other is time period. The temperature treatments are room temperature and 4℃. The storage periods are divided into four times. Their times continued three month until nine month. There used polyethylene for packing materials. This experiment was investigated to storage condition about moisture, ash, bacteria, Escherichia coli, Staphylococcus aureus, mold and chromaticity. The contents value of moisture and ash are under standard of permission as 9.7 and 6.2 respectively. There were almost no significance about test microorganism in the storage temperature condition. There was statistical significance on the bacteria according to storage period. In terms of stroage temperature and period interaction, there was statistical significance on the Staphylococcus aureus and mold. Conclusion : The effect of storage treatments on S. tenuifolia Kitagawa mainly focused to time period treatment and time period-temperature interaction treatments, there were differences along with time period of storage about the bacteria and interaction with storage temperature and period about Staphylococcus aureus and mold.

Today, with the development of the Internet and mobile technology, consumers' purchasing patterns have shifted from offline to online. In addition, due to the recent COVID-19, online purchases have significantly increased, and accordingly, the courier industry for logistics delivery has also grown significantly. Various logistics robots are being operated in many industrial and can reduce the labor intensity and physical and mental fatigue of workers. However, if the logistics robot does not properly recognize the people or environment around it, it can lead to a serious accident. We conducted that how logistics robots can perform safe work in a working environment such as a logistics warehouse through the application of ISO/DIS 21448 (SOTIF) to autonomous logistics transport robots. This result is expected to contribute to the operation of unmanned logistics warehouses using AGV.
