When feeling the pulse, healthy man' pulse is the criterion for diagnosis whether you are a sick person. Healthy man is defined as one who is harmonious and not sick in sympathy with natural order. Among the factors for being Healthy man, breathing and pulsation, Chon-gu(寸口) and Inyeong(人迎) are most closely connected with the representative methods of feeling the pulse which are used currently. According to "Hwangjenaegyeong(黃帝內經)" on breathing and pulsation, the pulse beats twice per a breathing-in and a breathing-out each. And for a specific breathing, it beats 5 times including the remnant with a big breath. That the pulse beats twice means that it beats not only twice, but also regularly and repeatedly. The remnant is related to the meaning on a leap month, 5-time beating during a breath is connected with the contents of Osipyeong(五十營). A human is not always in stable and sticks to balance continuously with changes under the circumstances. So when it comes to a criterion how to measure the pulsation frequency, breathing is much more reasonable than pulsation and breathing calculated for a minute. According to "Hwangjenaegyeong(黃帝內經)", Healthy man is the person of whose Chon-gu and Inyeong are in order and much the same in response to each other. Although there is a minor difference in the meaning of term between Chon-gu and Gigu(氣口), Maekgu(脈口) in originally, it is used as almost same meaning when Chon-gu is used in opposition to Inyeong. Afterwards, depending on medical men, around neck or Chon-gu of the left hand are measured for Inyeong. However, Inyeong described in "Naegyeong(內經)" is Jokyangmyeong(足陽明) and it means the Hyeol(穴) around neck where the pulse beats, it looks like about the carotid area. Chon-gu is fall under Eum(陰) and Inyeong(人迎) is fall under Yang(陽). Therefore Chon-gu is continuous with eumgyeong(陰經) and Inyeong is continuous with yanggyeong(陽經). In addition, the pulse and the four seasons meet each other and Inyeong is a little stronger in spring summer and Chongu is a little stronger in fall winter.

Extranodal marginal zone B-cell lymphoma of the mucosa-associated lymphoid tissue (MALT lymphoma) is usually indolent. Although it was reported recently that about 20-30% cases of MALT lymphoma presented with a disseminated disease at diagnosis, it was described as a disease localized at diagnosis and remaining stable for a prolonged period. However, only a few cases of MALT lymphoma involved the lung and gastrointestinal tract all at once. We report a case of a 73-year-old man with disseminated MALT lymphoma. He presented with non-productive cough, initial chest radiograph showed a nodule in the right lower lobe. The diagnosis of stage IV MALT lymphoma was made by CT scan, video-assisted thoracoscopic excisional biopy, gastrofiberscopic biopsy and bone marrow biopsy. The lymphoma involved the lung, stomach and bone marrow at the time of diagnosis. Because he refused chemotherapy, he discharged after Helicobacter pylori eradication without chemotherapy. Regular follow-up examination did not show any evidence of disease progression over 22 months.

The hot water extract from Artemisia capillaris fermented with Hericium erinaceum mycelium (AC-HE) were assessed for the protection against oxidative modification of biological macromolecules and cell death. Antioxidant activity of AC-HE evaluated using 2,2-diphenyl-1-picrylhydrazyl radical, 2,2'-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid) radical and peroxyl radical scavenging assays. AC-HE showed 61.73% DPPH radical scavenging activity at $500{\mu}g/mL$, 97.39% ABTS radical scavenging activity at $250{\mu}g/mL$, and 44.18% peroxyl radical scavenging activity at $100{\mu}g/mL$. AC-HE were shown to significantly inhibited DNA strand breakage induced by peroxyl radical. AC-HE also prevented peroxyl radical-mediated human serum albumin modification. AC-HE effectively inhibited $H_2O_2$ induced cell death and significantly increased of the 11.47% cell survival at $100{\mu}g/mL$. AC-HE also decreased intracellular reactive oxygen species (ROS) levels in $H_2O_2$-treated cells. The results suggested that AC-HE can contribute to antioxidant and protected cells from oxidative stress-induced cell injury.

Changam, Lee Samman(1770~1845), who created his own handwriiting to be referred to as the three great writers of the late Joseon Dynasty, the valued 'beobgo'. Based on the calligraphy of the Han-Wi era, Lee Kwangsa who completed DonggugJinche was regarded as the teacher of the heart. In his later years, he wrote 『ChangamSeogyeol』 to teach how to use the right brush, revealing the basic principles of universal calligraphy and his own calligraphy. The typeface of Changam is completed by choseo through the establishment of haeseo geungol. For this, I valued Han-Wi's haeseo training, OnhuGanwon Han-Wi geungol shows a state without natural law. This shows that nature is the core and ultimate goal of Changam calligraphy theory. This is a return to the state of 'No law' at the height of the law, where eum-yang is created and bizarreness occurs when form, power and energy are promoted. On the other hand, he emphasized that jangbeob and pochi form IlunMujeog DeugpilCheonyeon when expressing naturalness as it is, without being bound by the old law. His typeface constantly tried to combine the beauty of Joseon's own calligraphy while sublimating nature into art. Thus, he acquired IlunMujeog, a body rich in geungol and full of vitality and dynamism. And DeugpilCheonyeon achieved aesthetics with the highest level of excellence, embodied as the original 'Haengunyusu Typeface', and further developed handwriiting and Calligraphy spirit of DonggugJinche in Honam province.

We determined the contents of 11 biogenic amines in 20 types of cabbage kimchi, 10 types of fish sauce, and 40 types of salted fish purchased from small- and medium-sized grocery stores in Gyeonggi-Do, Republic of Korea, from June to October 2017. The content of each of the biogenic amines in the various types of cabbage kimchi was slightly lower than that in detection amounts of each of the 10 types of biogenic amines and the values reported by Joe et al. The histamine content of all five types of anchovy sauce was lower than the limit set by the European Union (400 mg/kg), but that of three of the five types of sand lance sauce was higher. Analyzing the ratios of the contents of five highly toxic biogenic amines to those of the 11 biogenic amines yielded no quantitative correlation. The estimated daily intake of the five highly toxic biogenic amines in cabbage-kimchi and fermented fish was ${\leq}6mg$.

Patents for postharvest technology of fresh fruits, vegetables and mushrooms fluctuated in their filing number until the 2000s, but then there has been a steady increase in the 2010s, indicating that the technology has high growth potential in the international agricultural market. Using 551 valid patents for fresh fruits and 337 for fresh vegetables of 5 countries, patent trend of postharvest technology was analyzed in this study with two categorized technologies as packaging and storage. In Korea, patents from national research institutes such as the Korea Food Research Institute and Korea (Rural Development Administration) are dominated, and a number of patents for the postharvest storage of fresh vegetables by Mitsui Chemicals, a Japanese chemical company, have been registered. Agrofresh, a multinational company in the USA, holds a number of patents for postharvest storage of fresh fruit not only in its own country, but also in Japan and Europe. Postharvest technology of fresh fruits and vegetables was found to has a number of patents, mainly from national research institutes and multinational corporations, and this suggests that R&D and commercialization of the technologies are actively taking place.

Eum Yang Kwak, the aerial part of Epimedium koreanum, is widely used as a folk medicine for stimulant in man, tonic, and hypotensive purpose. The plant contains icariin (a specific flavonoid), magnoflorine (an alkaloid) and tannin, but their contents are not known until now. In this paper, a quantitative analysis method for them was developed. Determination of icariin and magnoflorine was successfully achived by high performance liquid chromatography equipped with a UV detector in the ranges of $0.1{\sim}0.4\;mg$ and $0.002{\sim}0.1\;mg\;per\;ml$ sample, respectively. Extraction of the plant was carried out with water or 50% ethanol using different decocting temperatures and times. Icariin was well extracted either by water ($100^{\circ}C$, 3hr) or 50% ethanol ($85^{\circ}C$, 1hr), and its content in the plant was measured to be 0.94%. On the other hand, magnoflorine was fully extracted by 50% ethanol ($85^{\circ}C$, 1hr), and its content was determined to be 0.16%. Therefore, decoction of the medicinal plant with water at $100^{\circ}C$ for 3hr turned out to be recommendable for the best extraction.

This study was conducted to investigate the quality characteristics of eight Kimchi cabbage cultivars and the effect of cold storage on the quality of two kinds of cabbage cultivars, such as 'CR-Nongshim', and 'Ryouckgwang'. Early planted and harvested cultivars at July showed that fresh weight was lower than late harvested cultivars at September, because early harvesting time of July was heavy rainy season at highlands of Gangwon province. The firmness was more than 10 N for all cultivars and 'Cheongock', 'Sanjanggoon', and 'Ryouckgwang' cultivars had high value of firmness among them. No differences among the cultivars were found in appearance, freshness, and texture evaluations at harvest. Sweetness and bitterness had statistical differences and showed high value in 'Ryouckgwang' and in 'CR-Nongshim' and 'Sooho'. Two Kimchi cabbage cultivars such as 'CR-Nongshim' and 'Ryouckgwang' were stored at $0^{\circ}C$, $2^{\circ}C$, $5^{\circ}C$, and room temperature ($25^{\circ}C$) with more than 90% RH. Significant difference was found in weight loss during room and low temperature storage. In general, weight loss of the Kimchi cabbages at room temperature was significantly increased by 15% within 3 days, whereas it was delayed at low temperature until 3 weeks on all Kimchi cabbage cultivars. Firmness of 'CR-Nongshim' was higher than 'Ryouckgwang' but there was no difference within low storage temperatures. Appearance among the sensory factors was a critical indicator to estimate storage periods. On the point of appearance, storage period at $0^{\circ}C$ was 1 week and $2^{\circ}C$ and $5^{\circ}C$ was 3 weeks and 1 week in 'CR-Nongshim' cultivar, respectively. The storage period of 'Ryouckgwang' cultivar was 2 weeks, 4 weeks, and 2 weeks, respectively. Conclusively, storage at $2^{\circ}C$ with more than 90% RH was recommended as optimum temperature to maintain quality in both cultivars.
