Abstract ▼

○ Ginseng and ginseng field soil were collected and ED-XRF elemental analysis was performed; Ginseng (Ba, Ca, Cl, Cu, Fe, K, P, Rb, S, Si, Sr, Zn, Zr), soil (Al, Ba, Ca, Co, Fe, K, Mg, Mn, Rb, Si , Sr, Ti, V, Zn, Zr) and statistical analysis and correlation analysis were performed, Sr, Ba elements h

○ Ginseng and ginseng field soil were collected and ED-XRF elemental analysis was performed; Ginseng (Ba, Ca, Cl, Cu, Fe, K, P, Rb, S, Si, Sr, Zn, Zr), soil (Al, Ba, Ca, Co, Fe, K, Mg, Mn, Rb, Si , Sr, Ti, V, Zn, Zr) and statistical analysis and correlation analysis were performed, Sr, Ba elements have positive correlation between ginseng and soil, other elements have found no significant correlation with each other. Appling statistical discriminant function analysis (DFA), soil and ginseng could be differentiated based on the discriminant functions of 15 and 13 elements respectively. And unknown ginseng or soil of ginseng field is thought to be inferred using these functions.
○ Ink on paper analysis could be categorized into several groups depending on media and intensity of writing. When analyzing writing inks of pens on printed materials such as contract or receipt, the paper contribution should be considered and in many cases subtracted. On the contrary, documents written on various sized clean papers such as A4 or letter paper were rarely affected by the paper because the elemental content of paper was totally different from analyzed pen inks. The second point to focus is intensity of writing of hand writing. Even the same pen could be interpreted different due to the amount of ink on paper. In that case some compensation should be calculated to give precise results.
○ Candles made of natural material are popular for their environment-friendly trait and health. There kinds of natural candles were considered in the study. Palm was and bee’s was contain combination of fatty acid and paraffin wax but soy was has no specific indicative material. For the fire-related evidences those components could lead to the intervention of candles.
