  • There are rarely effective methods to help visually impaired people when they want to know the expiration date of products excepted to only Braille. In this study, we developed an expiration date notification system based on YOLO and OCR for visually impaired people. The handicapped people can automatically know the expiration date of a specific product by using our system without the help of a caregiver, fast and accurately. The proposed system is worked by four different steps: (1) identification of a target product by scanning its barcode; (2) segmentation of an image area with the expiration date using YOLO; (3) classification of the expiration date by OCR: (4) notification of the expiration date by TTS. Our system showed an average classification accuracy of about 86.00% when blindfolded subjects used the proposed system in real-time. This result validates that the proposed system can be potentially used for visually impaired people.

  • The seller and the buyer write down the agreed details in the trade contract as trade contract clauses. In the case where a letter of credit is agreed to be the payment condition, the buyer shall open a letter of credit to the seller with the shipping date specified in the trade contract through its bank. In this case, the legal relationship between the performance date of the trade contract and the shipment date of the letter of credit, the change of the performance date of the trade contract due to the change of the trade contract and the change of the shipment date specified in the letter of credit, the seller's letter of credit A problem arises in the legal interpretation of the approval period and the change request period. Therefore, this paper analyzed the precedents of the Seongnam Branch of the Suwon District Court and the Seoul High Court related to these legal issues. The performance date of a trade contract is the seller's delivery date and the buyer's payment date. In the letter of credit transaction, the date of performance of the trade contract is regarded as the date of shipment and the date of negotiation of documents specified in the letter of credit. The seller must decide whether to accept the letter of credit within 5 banking days after receiving the letter of credit from the buyer. After this period has elapsed, the seller cannot refuse the letter of credit. However, if the buyer is unable to decide whether to accept the letter of credit within 5 banking days due to reasons attributable to the buyer, the delivery date specified in the letter of credit will be extended. If the seller requests an amendment to the letter of credit, the buyer must accept it and open the letter of credit the seller desires to the seller. If the buyer refuses the seller's request to change the letter of credit, company A has the obligation to change and reopen the letter of credit as requested by company B. Expect by agreeing on the quotation As it is a fundamental breach of contract stipulated in Article 25 of the United Nations Convention on Contracts for the International Sale of Goods, company B can cancel the trade contract and claim damages from company A. Compensation for damages caused by Company A's breach of the trade contract shall be an amount equal to the loss suffered by Company B as a result of the breach, including loss of profits.

  • The concentration of airborne pollen is related to meteorological parameters. The main purpose of this study was to determine the correlation between airborne pollen and meteorological parameters in Ulsan based on sampling from 2010 to 2011. The primary factors of interest were differences in the pollen scattering start date, end date, and peak date, and the fluctuations in pollen concentration. The meteorological parameters that affected the start and peak dates of the pollen season were as follows. For Pinus and Alnus, the dates were correlated with sunshine and an increase in temperature, whereas for Quercus, the dates were correlated with increasing temperature. During the pollen season, Alnus peaked when the temperature was highest and Pinus peaked when the relative humidity was lowest. The concentration of airborne pollen was correlated with meteorological parameters during the sampling period as follows: Pinus, Alnus, and Humulus pollen concentrations were positively correlated with increasing temperature and negatively correlated with rainfall and relative humidity; Humulus pollen concentration was positively correlated with sunshine; and Quercus and Humulus pollen concentrations were positively correlated with wind speed.

  • Media components, including date juice, sodium acetate, peptone, and $K_{2}HPO_4$, which were screened by Plackett-Burman fractional factorial design, were optimized for lactic acid production from date juice using the response surface method (RSM). Sodium acetate, peptone (p<0.0001), and $K_{2}HPO_4$ (p=0.0029) were highly significant in influencing the lactic acid production. Close correlationship between predicted and experimental values was observed. When the optimum values of the parameters obtained through RSM (25.0 g/l date sugar, 15.0 g/l sodium acetate, 19.1 g/l peptone, and 4.7 g/l $K_{2}HPO_4$) were applied, lactic acid production (22.7 g/l) increased by 50.33%, compared with unoptimized media (15.1 g/l). The subsequent validation experiments confirmed the validity of the statistical model.

  • Present studies were carried out to clarify the variation of flowering date in the variants of Korean ginseng Plants. In general, the variation of flowering date of violet-stem variant was found to be mere variable as compared with that of yellow-berry variant. And flowers began to bloom earlier in yellow-berry variant than in violet-stem variant. In violet-stem variant as well as in yellow-berry variant, the flowering date of 5-year old plants was earlier than that of 3- and 4-year old plants. As for the flowering date according to the different lines, the third line was earlier than the first or the fifth line.

  • Sixteen microsatellite markers (simple sequence repeat (SSR) markers) were employed to examine the genetic stability of 27 randomly chosen date palm (Phoenix dactylifera L.) plants produced through somatic embryogenesis with upto forty two in vitro subcultures. No microsatellite DNA variation was observed among all micropropagated plants. Our results indicate that the micropropagation protocol used for rapid in vitro multiplication is appropriate and suitable for clonal propagation of date palm and corroborated that somatic embryogenesis can also be used as one of the safe modes for production of true-to-type plants of date palm. This is the first report on the use of microsatellite DNA markers to establish the genetic stability in micropropagated date palm plants.

  • Purpose: This study was conducted to identify the factors influencing the experience of sexual violence victims while dating as College Students. Methods: With a correlational survey design, data was collected by self-report questionnaires from 560 college students who had reported sexual violence during a date. The data was analyzed using descriptive statistics, t-test, ANOVA, Pearson correlation coefficients, and stepwise multiple regression. Results: College students while on date who reported sexual violence showed a significantly negative correlation with self-esteem, dating sexual assault recognition, sexual assertiveness, and significantly positive correlations with the gender role stereotypes, sexual violence permissiveness, date sexual violence inflictions, and family violence. A combination of date sexual violence inflictions, self-esteem, sexual violence permissiveness, sexual assertiveness all accounted for 41% of the variance in date sexual violence among college students. Conclusion: Self-esteem and sexual assertiveness must be progressively uplifted in order to prevent date sexual violence. A specific program established to reduce sexual violence permissiveness would be useful in order to reduce the number of sexual violence victims for college students who are dating.

  • In the past, several construction projects have exceeded their schedule resulting in financial losses to the owners; at present there are very few methods available to accurately forecast the completion date of a project. These nay be because of unforeseen outcomes that cannot be accounted for earlier and because of deficiency of proper tools to forecast completion date of said project. To overcome these difficulties, project managers may need a tool to predict the completion date at the early stage of project development. Bayesian Inference introduced in this paper is one such tool that can be employed to forecast project progress at all construction stages. Using this inference, project managers can combine an initially planned project progress (growth curve) with reported information from ongoing projects during the development, and in addition, dynamically revise this initial plan and quantify the uncertainty of completion date. This study introduces a theoretical model and proposes a mathematically information-based framework to forecast a project completion date that corresponds with the actual progress data and to monitor the modified uncertainties using Bayesian Inference.

  • In order to find out optimum seed production date according to different defoliation and flooding period of Italian ryegrass, this studies with Tetrone were canied out on the experimental field of Honam Crop Experiment Station from 1986 to 1988. Treatments included cutting date of Nov. 20 and Apr. 10 and flooding period of 5-25 days. In soil after experiment, organic matter, phosphate and silicate content increased, but potassium content decreased 0.16% than that before experiment. Heading and maturing date of Nov. 20 cutting were same with those of non cutting, those of Apr. 10 cutting lates 6 days to heading date and 2 days to maturing date. Plant height and culm length of Nov. 20 cutting were sirniller to those of non cutting, those of Apr. 10 cutting were shorter and panicle length have no difference between non cutting and cutting. Lodging of cutting treatment was reduced than that of non cutting. Lodgin was increased as flooding period was long, also loding of all treatment occured at 30 days after heading. Two cutting times of Nov. 20 and Apr. 10 have the most fresh yield, while non cutting have the most dry matter yield. Optimun seed productin date was considered to suitable when 35 days after heading (Jun. 14), at this time, seed production was 1,640 to 2,640 kg/ha. Also if flooding j u r y have, seed production was good between 10 days and 15 days after flooding.
