Background: Daily usage of facial masks during coronavirus disease 2019 pandemic influ- enced on facial dermatoses. Objective: This study investigated the impact of mask-wearing habits on facial dermatoses. Methods: A nationwide, obser vational, questionnaire-based sur vey was conducted from July through August 2021, involving 20 hospitals in Korea. Results: Among 1,958 facial dermatoses, 75.9% of patients experienced aggravation or development of new-onset facial dermatoses after wearing masks. In aggravated or newly developed acne patients (543 out of 743), associated factors were healthcare provider, female gender, and a long duration of mask-wearing. Irritating symptoms, xerosis, and hyperpigmentation were more frequently obser ved in this group. Aggravated or newly developed rosacea patients (515 out of 660) were likely to be female, young, and have a long duration of mask-wearing per day. Seborrheic dermatitis patients who expe- rienced aggravation or de novo development (132 out of 184) were younger, and they more frequently involved the chin and jaw in ad- dition to the nasolabial folds and both cheeks. Contact dermatitis patients (132 out of 147) with aggravation or de novo development tended to be female, involve both cheeks, and complain of pruri- tus. Aggravated or newly developed atopic dermatitis patients (165 out of 224) were more likely to be female, and had a higher baseline investigator global assessment score before mask-wearing. Conclusion: Clinical features and factors related to aggravation were different according to the types of facial dermatoses.

In the past years, few grain sorghum varieties with limited yield potential have been developed and grown in Korea. Hybrids tend to be more productive and resistive to unfavorable environmentalconditions than pure line varieties. However, no hybrid cultivars are available and never have been planted for grain sorghum in Korea. The main aims of this study were to (i) verify if US xKorean and US x US hybrids increase grain yield in Korea; (ii) assess the performance of waxy hybrids in Korea and the US; (iii) estimate general combining ability and specific combining abilityfor the lines studied; and (iv) identify superior lines and hybrids for future use in breeding. Two distinct sets of waxy-endosperm sorghum hybrids derived from Korean landraces and US lines (TexasA&M University) were tested in the US and Korea. Compared to the parental lines, hybrids derivedfrom US lines and Korean landraces showed yield increase that ranged from 2% to 127%. Hybridscreated from US lines showed higher heterosis than US x Korean hybrids. Hybrid vigor was observedin the US and Korea, but shifts in ranks of hybrid performance occurred. The results indicate that it isfeasible to develop grain sorghum hybrids adapted to Korean conditions only if delibrate selectionstake place in Korea. A combination of Korean and US sources could provide an acceptable germplasmbase for developing Korean landrace based sorghum hybrids.

최명은,임동준,장성은,이미우,최지호,이우진 대한피부과학회 2020 Annals of Dermatology Vol.32 No.5

Pseudomyogenic hemangioendothelioma (PMH) is a rare vascular tumor and was recently recognized as a distinct entity. It has a predilection for young male adults and it frequently occurs in distal extremities. Although it is known to follow an indolent course, multi-focal presentation and local recurrence are common. PMH should be differentiated from epithelioid sarcoma, epithelioid hemangioendothelioma, dermatofibrosarcoma protuberans, and rhabdomyosarcoma. Its characteristic immunohistochemical staining pattern and recurrent translocation t(7:19)(q22:q13) are the basis for its diagnosis. Surgical excision is the mainstay treatment, although chemotherapy can be considered in non-operable patients. We present a rare case of a 40-year-old Korean male patient diagnosed with PMH through an excisional biopsy to facilitate the recognition PMH in the clinical practice.

A few inbred grain-sorghum varieties were developed and grown in Korea and they all have low productivity. Hybrid cultivars have been demonstrated to be more productive and resistive to unfavorable environmental conditions than pure line varieties. However, few studied have been conducted on hybrid sorghum in Korea; therefore, information on combining ability of landraces based on parental materials is needed for hybrid breeding program to increase production. This study was conducted to determine the combining ability of Korean landrace sorghum varieties and cultivars. Two cytoplasmic male-sterile lines (A.Arg-1, A03017) were crossed with 13 male-fertile lines to generate 26 experimental hybrids. The hybrids were evaluated at Daegu and Miryang in Korea in 2018. Grain sorghum hybrids were planted with three replicate and standard agronomic practices were followed at both sites. There were significant (P=0.001) variation among genotypes for yield and secondary traits. For each trait, general combining ability (GCA) and specific combining ability (SCA) effects were estimated using the line-tester method. The positive heterosis for grain yield was observed in hybrid. The A03017 × Sodamchal hybrids exhibiting better parent heterosis of up to 54.1%. The lines 18AYT-S04 and Sodamchal displayed significant and positive GCA effects for grain yield, and A03017 × Sodamchal crosses showed positive and greatest SCA effects. The crosses, A.Arg-1 × 18OYT-S17, A.Arg-1 × Sodamchal and A.Arg-1 × 18OYT-S01, had high grain yield value with waxy endosperm, would be recommended for produced and used in grain sorghum breeding program in Korea.

The sorghum (Sorghum bicolor (L.) Moench) variety ‘Noeulchal’ was developed and registered by the Department of SouthernArea Crop Science, National Institute of Crop Science, in 2019. This variety was developed from the cross between ‘RTx2907’, with whitegrain, and ’Sodamchal’, with brown grain and semi-dwarf traits. The yield performance of ‘Noeulchal’ was 3.71 MT/ha in a local adaptabilitytest run for two years. It had a culm length of 93 cm, which is 11 cm longer than that of ‘Sodamchal’, a panicle length of 29 cm, a culm22 mm thick, and a panicle exsertion of 9 cm. It could reduce the lodging problem experienced with current cultivars, and is also adaptedto mechanized cultivation. ‘Noeulchal’ has a waxy endosperm with 3.2% amylose and contained high levels of rapidly digestible starch. Therapidly digestible starch with gluten-free flours could contribute to the development of foods with different properties (Registration No. 9105).

Sorghum is a rich source of various phytochemicals including phenolic compounds thathave potential to significantly benefit human health. Phytochemical production may be induced not onlyby genotype but also by a number of environmental factors including temperature and an amount ofsunshine. The objective of this study was to determine the effect of planting dates and harvesting stageson the quality traits of ‘Donganme,’ a grain sorghum variety developed to produce high antioxidants. ‘Donganme’ was planted in three locations on four dates from early May to early July. Each plantedfraction was harvested 35, 40, 45, 50, and 55 days after the head shooting date, respectively. The resultsshowed that significant differences existed between the growth period and content of polyphenol and flavonoid. The sorghum harvested at 35 days after head shooting had the higher polyphenol and flavonoidcontent in all planting times and the tannin content was increased as the planting date was delayed. Sothe sorghum grown in late planting dates (July 5) had highest polyphenol content (2.07 gGAE/100g) atearly harvesting (35 days) while late planting gave the low grain yield (1.3 ton/ha). Polyphenol index toaverage temperature during 35 and 45 days after heading of ‘Donganme’ showed that total polyphenolcontents were decreased by 5.2% and 4.4%, respectively, with increasing average temperature of 1oC. And high correlation (R=0.85) was observed between accumulated temperature and the amount of polyphenolof ‘Donganme’, confirming the major contribution of the quality traits is temperature. To producehigh quality grain from sorghum the relation between the yield and nutrition components must beconsidered simultaneously (i.e., Sorghum produced the highest polyphenol and flavonoid when plantedin June 15 and harvested at 40 to 45 days after head shooting . 1. 본 연구는 항산화 활성이 우수한 수수품종 ‘동안메’의 지역별 파종시기 및 수확시기에 따른 기능성물질 발현 및 항산화 활성변이를 분석하여 고품질 수수를 생산할 수 있는 재배기술의 기초자료를 얻고자 수행하였다. 2. 지역, 파종시기, 수확시기에 따른 특성분석결과 지역과 파종시기, 파종과 수확시기, 지역별 파종 및 수확시기 모두 유의성을 가졌다. 기능성 성분(폴리페놀, 플라보이드)과 항산화활성(ABTS, DPPH)이 동일한 경향치를 보였는데 종실 100g당폴리페놀 함량의 경우 7월 5일 파종 및 출수 후 35일 수확에서 가장 높았다. 3. 파종시기별 수량성은 6월 15일 파종에서 가장 높았으며(452.2 kg/10), 6월 15일 파종 출수 후 40~45일 수확에서 가장 높은 폴리페놀과 플라보노이드 생산량을 가졌다. 4. 출수 후 평균적산온도, 일사량과 기능성 성분 함량의 상관관계 조사결과 상관계수 R값이 각 0.85, 0.82로 부의 상관관계를 가졌고, 출수 후 35일 수확과 45일 수확에서 평균기온이 1oC 증가할 때마다 폴리페놀 함량이 각 5.2%, 4.4% 감소하였다.

“风在吼.马在叫.黄河在咆哮”——中国河南河北漫谈

崔明,宁雨霏 상명대학교 한중문화정보연구소 2021 中國地域文化硏究 Vol.15 No.-

About five thousand years ago, ancient China, ancient Egypt, ancient India, Babylon, and ancient India entered civilized society almost at the same time. These four ancient civilizations were all established in large river basins above their respective continents. These four ancient civilizations basically represent the peak of the development of typical agricultural civilizations on the earth. Together with typical marine civilizations such as ancient Greece and Rome that developed along the Mediterranean coast, they constitute the world's most extensive types of civilizations and development models. At present, the academic circles have a lot of research on the overall discourse of marine civilization and Dahe civilization and the development of their causes, and the data is full. This article focuses on the two most important river basins in ancient China, a country with an uninterrupted history of civilization development: the Yellow River Basin and the Yellow River Basin, one of the Yangtze River basins, and two "neighbor" provinces derived from the geographical concept of the Yellow River Basin. : The history, geography, and humanities of Hebei Province and Henan Province are comprehensive, and explore the status quo of the emergence and development of the Dahe Civilization in China’s "Northern Central" to today. And after the development of ancient north-central China to modern society, the way to deal with future challenges from the overall national level. 在大概五千年前,古中国古埃及古印度古巴比伦,几乎同时进入了文明社会。这四大文明古国都是在各自大陆上面的大河流域建立起来的。这四大文明古国基本上代表了地球上面典型农业文明发展的高峰。它们和以环地中海沿岸发展起来的古希腊古罗马这样典型的海洋文明一起,构成了世界上最广泛的文明类型和发展模式。目前学界对于海洋文明和大河文明的整体论述和产生原因发展脉络之研究汗牛充栋,资料充盈。本文着重从古中国这个文明发展史从未中断过的国家,两条最重要的大河流域:黄河流域和长江流域之一的黄河流域,从黄河流域地理概念上衍生命名的两个“邻居”省:河北省和河南省的历史、地理、人文的综合方面,探究一下大河文明在中国“中北部”的产生发展到今天的现状。以及在古老中国中北部地区发展到现代社会的今天以后,从整体国家层面整体面对未来挑战的应对方式。
