  • 자동차용 내외장재로 사용하는 열가소성 엘라스토머(thermoplastic elastomer, TPE)로 제조한 시험편 표면에 340 nm의 자외선을 총 $2500\;kJ/m^2$ 조사하였다. 자외선 조사 후 검정 시험편 표면은 뿌옇게 변했다. 노화 전후 시험편 표면에 있는 물질을 채취하여 GC/MS로 분석하였으나 특이한 점이 발견되지 않았다. 노화된 시험편의 표면에서 잔크랙이 다수 발견되었다. 노화된 시험편의 백화 현상은 노화된 표면을 솔질하거나 불로 지지면 사라졌다. 솔질이나 불로 지진 후에는 표면에 있던 잔크랙이 사라졌다. 노화 전후의 시험편과 노화된 시험편 표면을 솔질 혹은 불로 지진 후의 시험편을 영상 분석기, SEM, EDX, ATR 등으로 분석하여 비교한 결과, 솔질이나 불로 처리한 후 제거된 백화 현상은 솔질이나 불에 의한 가열로 TPE의 구성 성분 중 하나인 폴리프로필렌이 잔크랙을 메웠기 때문으로 설명할 수 있다.

  • This study compared the quality, cooking, textural, and palatability characteristics between sous-vide (SV) cooked pork loin patties with different searing treatments (ST). Before SV cooking, STs were conducted on each side of the pork loin patties for 0 (control) to 120 s (ST120), and all patties were then cooked using an SV cooker at 75℃ for 120 min. Noticeable differences were observed in quality properties between the groups. The seared SV loin patties exhibited lower lightness and higher browning index values compared to the unseared SV loin patties (p<0.001). Cooking loss gradually increased with increasing ST times, and the control group had a lower percentage compared to the ST60 group (19.5 vs. 25.7%, p<0.001). Changes in cooking properties were associated with the extent of ST, and the ST groups exhibited a higher hardness value compared to the control group (p<0.001). Regarding palatability, loin patties from the control group scored lower in appearance acceptability compared to patties from the ST groups (p<0.05) due to extent of browning on the surface. Moreover, the ST groups did exhibit a higher flavor intensity compared to the control group, but no differences were observed in tenderness and juiciness scores between the control and ST60 groups. Due to these results, the ST60 group exhibited a greater score in overall acceptability compared to the other groups except for the ST90 group. Therefore, an additional ST before SV cooking can achieve a more appealing appearance and palatability as well as to enhance the availability of pork loin.

According to "Guide to Swollen Sore Treatment", we could noted frequent application of blood letting methods in the affected area, then rinse ones mouth with salty water and further application of taro plaster. Also found acupuncture methods utilizing heated mole cricket or silkworm in the sublingual region. Regarding herbal method, Realgar was rubbed in the affected area. Mainly used acupuncture points in the treatment of oral, glottal, labial and dental diseases were GV20, GB20, LU5, and auricular anterior hairline 2. In "Treasured Mirror of Eastern Medicine", blood letting method in the sublingual region and burning needle searing method were the most frequently applied in the treatment of oral, glottal, labial and dental diseases. Moxibustion was also applied in the treatment of labial and dental diseases. Particularly, said to apply 3 moxa cones in ear zones of both sides, when no medicine is effective. This demonstrates how emphasized the importance of moxibustion in this kind of disease. Mainly used acupuncture points were GV16, CV24, LI4, EX-HN12, and EX-HN13 3. In "Experiential Prescriptions of Acupuncture and Moxibustion", no other methods beside wrist. Superstitious methods like applying moxibustion on the tooth picture drawn on the roofing tile need further confirmation. Mainly used acupuncture points were LI4, ST36, and HT7. 4. "Essential Rhymes on Acupuncture and Moxibustion by Master Sa-am", identified the cause of diseases according to visceral pattern identification.
