점자를 제외한 시각 장애우들이 유통기한을 확인할 수 있는 효과적인 방법이 거의 개발되어 있지 않으며, 이로 인하여 시각 장애우들의 식품 안전성이 위협받고 있다. 본 연구에서는 시각 장애우의 식품 안전성 확보를 위해 실시간 객체 인식 알고리즘(you only look once, YOLO) 및 광학 문자 인식 (optical character recognition, OCR)에 기반한 유통기한 알림 시스템을 개발했다. 제안하는 시스템은 총 4가지 단계로 시각 장애우에게 유통기한 정보를 전달한다: (1) 표적 제품의 바코드 스캔을 통한 제품 확인 (2) 실시간으로 입력되는 제품 영상에서 YOLO 알고리즘을 활용하여 유통기한이 표기된 이미지 영역 검출; (3) 검출된 이미지 영역에서 OCR 알고리즘을 활용하여 유통기한 문자 인식; (4) Text to Speech (TTS) 기술을 활용하여 유통기한 정보를 사용자에게 전달. 성능 평가를 위한 온라인 실험 결과, 앞이 보이지 않는 피험자가 개발한 시스템을 사용해서 제품의 유통기한을 평균 86%의 높은 정확도로 확인할 수 있음이 검증되었다. 이러한 결과는 제안하는 시스템이 저시력자를 포함한 시각 장애우들의 식품 안전성 확보에 이바지할 수 있음을 보여준다.

무역계약의 이행기일은 매도인의 물품인도 기일과 매수인의 대금지급 기일이다. 신용장거래에서 무역계약의 이행기일은 신용장에서 명시된 선적기일과 서류매입기일로 본다. 매도인은 매수인으로부터 신용장을 받고나서 5 은행영업일 이내에 신용장의 승낙 여부를 결정하여야 하며 이 기간이 경과하면 매도인은 신용장을 거절할 수 없다. 그러나 매수인의 귀책 사유로 인하여 5 은행영업일 이내에 신용장의 승낙 여부를 결정하지 못하는 경우에는 신용장에 명시된 선적기일까지 연장된다. 매도인이 신용장 변경을 요청한 경우에 매수인은 반드시 이를 수락하여 매도인이 원하는 신용장을 변경하여 매도인에게 개설하여야 한다. 매수인이 매도인의 신용장 변경 요청을 거절하면 A사는 B사가 요청한 대로 신용장 내용을 변경하여 다시 개설할 의무가 있고 A사가 단순히 신용장의 변경을 지체한 것이 아니라 B사의 신용장 요청을 거절한 경우에는 B사가 견적서에 합의하여 기대할 수 있는 바를 실질적으로 박탈하는 것으로 국제물품매매계약에 관한 국제연합협약 제25조가 규정한 본질적인 계약위반에 해당되어 B사는 무역계약을 해제할 수 있고 A사에게 손해배상을 청구할 수 있다. A사의 무역계약 위반으로 인한 손해배상액은 이익의 상실을 포함하여 그 위반의 결과 B사가 입은 손실과 동등한 금액으로 하여야 한다.

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.
