농산물 선별 시스템은 작물의 형태를 보전하기 위하여 비파괴적인 선별이 주로 사용된다. 이러한 비파괴 선별 기술로는 가시광선, 근적외선, 엑스선, 감마선 등의 광학적 특성을 이용하고 있으며 본 논문에서는 엑스선을 이용한 선별을 이용한다. 엑스선 영상은 엑스선의 밀도에 따라 그레이 영상으로 생성되어 육안으로 시료의 결함을 감지하기가 어렵다. 미세한 결함을 발견하기 위해서는 영상을 확대하거나 픽셀의 범위를 수정하여 적정한 픽셀의 영역만을 표시하여 결함을 탐지해야 한다. 이런 작업은 비효율적이다. 따라서 본 논문은 엑스선의 광역적인 밀도와 지역적인 밀도에 대한 상대적인 밀도를 측정하여 색상화된 결함을 표시하는 새로운 방법을 제안한다. 하나의 픽셀에 대한 상대적인 밀도는 주위 픽셀과의 상대적인 차이를 나타내며, 이런 픽셀을 정상과 결함으로 나타내는 엑스선 영상의 색상화 방법도 제안한다. 실험에서는 육안으로 볼 수 없는 농작물의 병해충 또는 새싹 부분을 특정 색으로 색상화 하여 농산물 선별 시스템에 활용할 수 있게 하였다. 제안된 방법은 엑스선을 이용한 선별 시스템에 적용되어 농산물 선별 시스템뿐만 아니라 가공식품, 부품 제조와 같은 제조 공정에서 사용되어 불량품을 선별하는 방법에 적극적으로 이용될 수 있을 것이다.

The purpose of this research is to investigate changes in ethical consumption practices after taking an undergraduate course 'Consumption and Ethics'. Through Qualitative & Quantitative research methods, students' pre-course and post-course attitudes were compared to understand changes in behavior. Before taking the course 'Consumption and Ethics', undergraduate participants displayed little regard for ethical consumption, instead displaying primary sensitivity to price and values based on self-centered and conspicuous consumption. After taking the course 'Consumption and Ethics', participants displayed a more altruistic awareness of consumption on society and the environment. In addition, participants displayed a stronger sense of pride as ethical consumer. These emerging values were contrasted with conflicting feelings resulting from the higher prices often associated with ethical products, feelings of regret resulting from ethically-based impulse purchases, and an inability to categorically evaluate the reliability of available information on the ethical products. However, participants demonstrated a willingness to practice ethical consumption and recommend ethical consumption to their friends and neighbors. Overall, participants in the study demonstrated a strong shift to be an ethical consumer as a result of taking the course 'Consumption and Ethics'.

This study utilized a standardization and cluster analysis technique for the selection and classification of beneficial bacteria. A set of synthetic data consisting of 100 individual variables with three characteristics was created for analysis. The three characteristics assigned to each independent variable were designated to have different numeric scales, averages, and standard deviations. The variables were bacterial isolates at random, and the three characteristics were fermentation products, including cell yield, antioxidant activity of culture, and enzyme production. A standardization method utilizing a standard normal distribution equation to record fermentation yields of each isolate was employed to weight their different numeric scales and deviations. Following transformation, the data set was analyzed by cluster analysis. The Manhattan method for dissimilarity matrix construction along with complete linkage technique, an agglomerative method for hierarchical cluster analysis, was employed using statistical computing program R. A total of 100 isolates were classified into groups A, B, and C. In a comparison of the characteristics of each group, all characteristics in groups A and C were higher than those of group B. Isolates displaying higher cell yield were classified as group A, whereas those isolates showing high antioxidant activity and enzyme production were assigned to group C. The results of the cluster analysis can be useful for the classification of numerous isolates and the preparation of an isolation pool using numerical or statistical tools. The present study suggests that a simple technique can be applied to screen and select beneficial microbes using the freely downloadable statistical computing program R.

For research, we compare to IBM of consumer awareness surveys an AI shopping information service for retailing channel and target goods group. Finally, we present to service scenario for distribution service using AI. Research design, data, and methodology - First, to identify possible the success of the information service shopping using AI, AI technology for the consumer is very important for the acceptance of judgement. Therefore, we explored the possibility of AI information service for business as a shopping. The experimental data were used to interpret the meaning of the relevant literature and the IBM Institute of Business Value (IBV) Report 2015. This research is based on the use of a technical acceptance model (TAM) to determine whether the consumer would adopt the 'AI shopping information service' technology. Step 1 of the process assumes that the consumer adopts AI technology. In step 2, consumers find their preference channels and goods targeted at them as per their preferences. Finally Step 3, we present scenario for 'AI shopping information service' based on the results of Step 1 and 2. Results - Consumers have expressed their high interests in the new shopping information services, especially the on/off line distribution channels can use shopping information to increase the efficiency in provision of goods. Digital channel (such as SNS, online shopping etc.) is especially high value goods such as cars, furniture, and home appliances by displaying it to an appropriate product group. Conclusions - The study reveals the potential for the use of new business models such as 'AI shopping information service' by the distribution industry. We present seven scenario related AI application refer from IBM suggestion, and the findings would enable the distribution industry to approach target consumers with their products, especially high value goods. 'Shopping advisor' is considered to the most effective. In order to apply to the other field of the distribution industry business, which utilizes AI technology, it should be accompanied by additional empirical data analysis should be undertaken.

Genomic DNAs were extracted from the muscle of twenty-two specimens of two shortnecked clam, Ruditapes phifippinarum populations collected in Anmyeondo and Seocheon. Genetic differences within and between populations were analysed by random amplified polymorphic DNAs-polymerase chain reaction (RAPD-PCR) using twenty arbitrary decamer primers. Out of 20 primers, 6 generated a total of 1,111 major and minor RAPD bands from individuals of two sites, producing approximately 4.2 average polymorphic bands per primer in individuals from Anmyeondo and ranging in size from less than 50 to larger than 1,500 base pairs (bp). The electrophoretic analysis of RAPD products amplified showed moderate levels of similarity among the different individuals in Seo-cheon population. The average bandsharing values (BS value) of the samples within population from Anmyeondo ranged from 0.155 to 0.684, whereas it was 0.143∼0.782 within population from Seocheon. The average BS value between individuals No. 13 and No. 14 from Seocheon was 0.782 which was higher than that of those from Anmyeondo. The single linkage dendrogram resulted from three primers (OPA-08, -09 and -20), indicating six genetic groupings composed of group 1 (No.4, 8 and 10), group 2 (No. 18), group 3 (No.2, 5 and 7), group 4 (No. 1, 3, 6, 9, 11, 12, 13, 14, 15 and 17), group 5 (16, 19 and 20) and group 6 (No. 21 and 22). In the Seocheon population, the individual No. 18 clustered distinctly from the others of this population. The observed genetic distance between the two populations from Anmyeondo and Seocheon was more than 0.209 (0.247 and 0.275). The shortest genetic distance (0.094) displaying significant molecular differences was between individuals No. 13 and No. 14. Especially, the genetic distance between individuals No. 22 and the remnants among individuals in two geographical populations was highest (0.275). This result illustrated that individual No.22 is distinct from other individuals within two shortnecked populations. The different geographical features of two sites may have caused the genetic diversity in two shortnecked clam populations.
