Background and purpose: The chronic diseases caused by lifestyle are on the increase. This study aims to review the eating habits as etiological factors and related symptoms from the perspective of Korean medicine. In this process, we will make a proposal on the treatment of the lifestyle related diseases. Methods: We studied the sentences about the eating habits and related diseases in Donguibogam Results and Conclusions: 1. The eating habits as etiological factors are overeating, irregular eating, late-night foods, fatty & heavy foods, cold foods, alcohols, etc. 2. The diseases caused by the eating habits are not limited to the gastrointestinal diseases(stomachache, vomiting, diarrhea, etc) but include the non-gastrointestinal diseases(edema, arthralgia, anal diseases, eye diseases, ear diseases, diabetes, cancers, etc.) 3. In the treatment of the diseases caused by the eating habits, the special regard should be paid to the etiological factors.

A basic characterization of uranium samples was performed using gamma- and X-ray spectroscopy. The studied uranium samples were eight types of certified reference materials with $^{235}U$ enrichments in the range of 1-97%, and the measurements were performed over 24 h using a high-resolution and high-purity planar germanium detector. A general peak analysis of the spectrum and the $XK_{\alpha}$ region of the uranium spectra was carried out by using HyperGam and HyperGam-U, respectively. The standard reference sources were used to calibrate the spectroscopy system. To obtain the absolute detection efficiency, an effective solid angle code, EXVol, was run for each sample. Hence, the peak activities and isotopic activities were determined, and then, the total U content and $^{234}U$, $^{235}U$, and $^{238}U$ isotopic contents were determined and compared with those of the certified reference values. A new method to determine the model age based on the ratio of the activities of $^{223}Ra$ and $^{235}U$ in the sample was studied, and the model age was compared with the known true age. In summary, the present study developed a method for basic characterization of uranium samples by nondestructive gamma-ray spectrometry in 24 h and to obtain information on the sample age.

Microbial dysbiosis in the gut is associated with human diseases, and variations in mucus alter gut microbiota. Therefore, we explored the effects of mucin on the gut microbiota using a community of 19 synthetic gut microbial species. Cultivation of these species in modified Gifu anaerobic medium (GAM) supplemented with mucin before synthetic community assembly facilitated substantial growth of the Bacteroides, Akkermansia, and Clostridium genera. The results of 16S rRNA microbial relative abundance profiling revealed more of the beneficial microbes Collinsella, Bifidobacterium, Ruminococcus, and Lactobacillus. This increased acetate levels in the community cultivated with, rather than without (control), mucin. We identified differences in predicted cell function and metabolism between microbes cultivated in GAM with and without mucin. Mucin not only changed the composition of the gut microbial community, but also modulated metabolic functions, indicating that it could help to modulate microbial changes associated with human diseases.

본 연구에서는 농업폐기물인 감귤박의 효율적인 재활용 방안으로 고부가가치 제품인 활성탄을 제조하여 이용하는 가능성에 대하여 조사한 결과, 감귤박 폐액으로부터 건조한 시료의 조성은 대부분이 탄수화물로 구성되어 있으며, 또한 이는 미생물, 농약 및 중금속에 오염되지 않은 순수한 천연 재료로 구성되어 있음을 알 수 있었다. 또한 탄화공정 및 활성화공정을 통해 제조된 활성탄의 요오드 흡착능이 KS 규격 중 1급(활성탄 1,100 mg/g 이상)보다 높은 값으로 나타나 공업용 활성탄으로의 활용이 가능할 것으로 사료된다.

수지합성 시 추출제의 고른 분산과 균일한 입자를 만들어 알루미늄과 철의 추출량을 증가시키고자 반응 개시제인 benzoyl peroxide(BPO)의 첨가법을 변화시킨 결과 세 번 나누어 첨가한 3pot의 성능이 가장 우수하였다. D2EHPA를 이용하여 합성한 수지의 경우 Fe와 Pt간에 Fe는 100% 추출되었으며, Al과 pt간의 분리실험에서 99.9%의 Al이 추출되었다. 수입되는 $P_{204}$ 수지 역시 Fe와 Pt간의 분리실험에서 100%의 Fe가 추출되었으며 Al과 Pt간의 분리실험에서는 98.9%의 Al이 추출되는 것을 확인하였다. 합성수지와 $P_{204}$내 추출제 함량은 각각 61.8, 60%이며, 이러한 차이가 추출효율에 차이를 가져오는 것으로 판단된다. 한편 두 수지 모두 $55^{\circ}C$까지는 Al과 Fe의 추출효율이 증가하나, 그 이상의 온도에서는 영향이 없는 것으로 확인되었다. FT-IR분석 결과 추출제에 따른 고유의 피크를 $1000cm^{-1}$에서 확인할 수 있었으며 합성한 추출 수지와 $P_{204}$ 수지 모두 $2900cm^{-1}$에서 가교 폴리스틸렌의 특징적인 피크를 확인하였다.

Objective : This research is aimed to compare the three sets of Dongin(K-1, K-2, K-3) to Chosun and Chinese acupuncture bronze men, and through literature review of acupuncture points and meridians to see how acupuncture of Chosun affected the Japan's acupuncture bronze men. Methods : Using 3D scanning, we compared the location of acupoints by the proportional bone measurement method of the three sets of Dongin to those of Chosun and China. We also compared the meridians and acupuncture points of the three sets of Dongin to Doningyosodo. Results : Dongin K-1 and K-2 have all the unique characteristics of ChimGuemDongIn. Their heads were made about 30% larger than the location of points by the proportional bone measurement method and their necks were shortened to get the right proportion. Their gender was not specified. Their hands were sticking forward, and knees were slightly bent, and the arms and legs were carefully crafted to record acupuncture points. Dongin K-1 and K-2 marked the meridians and acupuncture points according to Doningyosodo. In particular, BL39 in Dongin K-1 and K-2 has been marked as in ChimGeumDongIn, which is considered to have come from DongUiBoGam. These characteristics do not exist in Chinese acupuncture bronze men. The location of points by the proportional bone measurement method was marked on the right side of the Dongin K-3, while the eight extra meridians were marked on the left side. Conclusions : In summary, Dongin K-1 and K-2 indicate the Japanese history of acupuncture which may have influenced from Chosun.
