In order to deduce the pathogenic factor(PF) diagnosis logic of underlying in pattern identification of Korean medicine, 2,072 cases of DSOM(Diagnosis System of Oriental Medicine) data ​​from May 2005 to April 2022 were collected and analyzed by means of decision tree model(DTM). The entire data were divided into training data and validation data at a ratio of 7:3. The CHAID algorithm was used for analysis of DTM, and then validity was tested by applying the validation data. The decision rules of items and pathways determined from the diagnosis data of Qi Deficiency, Blood Deficiency, Yin Deficiency and Yang Deficiency Pathogenic Factor of DSOM were as follows. Qi Deficiency PF had 7 decision rules and used 5 questions: Q124, Q116a, Q119, Q119a, Q55. The primary indicators(PI) were 'lack of energy' and 'weary of talking'. Blood deficiency PF had 7 decision rules and used 6 questions: Q113, Q84, Q85, Q114, Q129, Q130. The PI were 'numbness in the limbs', 'dizziness when standing up', and 'frequent cramps'. Yin deficiency PF had 3 decision rules and used 2 questions: Q144 and Q56. The PI were 'subjective heat sensation from the afternoon to night' and 'heat sensation in the limbs'. Yang deficiency PF had 3 decision rules and used 3 questions: Q55, Q10, and Q102. The PI were 'sweating even with small movements' and 'lack of energy'. Conclusively, these rules and symptom information to decide the Qi·Blood·Yin·Yang Deficiency PF would be helpful for Korean medicine diagnostics.

In order to make a diagnosis of patient's Sasang constitution, oriental doctors use the Sasang constitution questionnaire for doctors(SSCQ-D). This check list has 105 questions and 88 items of them are used for Sasang constitutional discriminant function, and they are divided into four categories. To assess physical appearance, which is one of the four categories, we measure 5 widths and 8 circumferences of a patient's body by using the large sliding caliper and tape line. In this study, we use the 3D scanner ibs-2000 and measure the 5 widths and 4 vertical gaps between the widths level and compare the accuracy between the manual measurement and the non-contact measurement with a 3D scanner. We have collected 1724 questionnaires from the 5 oriental medical hospitals and classified them according to Sasang constitution, sex, age and BMI and made an analysis using the discriminant analysis model. In the case of female who were 33~64 years old and normal weight, the accuracy of the manual measurement was 76.78% and the non-contact measurement with the 3D scanner was 76.25%. As a result, there is little difference between the two measurements. We can use 5 widths and 4 vertical gaps as useful items to assess physical appearance.

Multi-shell graphite coated Ag nano particles with core/shell structure were synthesized by pulsed wire evaporation (PWE) method. Ar and CH_4 (10 vol.%) gases were mixed in chamber, which played a role of carrier gas and reaction gas, respectively. Graphite layers on the surface of silver nano particles were indiscretely coated. However, the graphite layers are detached, when the particles is heated up to 250 ℃ in the air atmosphere. In contrast, the graphite coated layer intact under inert gas of Ar and N_2, though the core/shell structured particles were heated up to 800 ℃. The multi-shell graphite coated Ag nanoparticles well dispersed in LSCF cathode after sintering up to 850 ℃. The graphite shell layer prevent agglomeration between Ag nanoparticles in La_(0.6)Sr_(0.4)Co_(0.3)Fe_(0.7)O_(3−δ) (LSCF) layer.

Multi shell graphite coated Ag nano particles with core/shell structure were successfully synthesized by pulsed wire evaporation (PWE) method. Ar and $CH_4$ (10 vol.%) gases were mixed in chamber, which played a role of carrier gas and reaction gas, respectively. Graphite layers on the surface of silver nano particles were coated indiscretely. However, the graphite layers are detached, when the particles are heated up to $250^{\circ}C$ in the air atmosphere. In contrast, the graphite coated layer was stable under Ar and $N_2$ atmosphere, though the core/shell structured particles were heated up to $800^{\circ}C$. The presence of graphite coated layer prevent agglomeration of nanoparticles during heat treatment. The dispersion stability of the carbon coated Ag nanoparticles was higher than those of pure Ag nanoparticles.
