Objectives: This study was conducted to analyze the salinity of representative Korean foods high in sodium to generate data for use as a fundamental resource for setting salinity standards in foods. Methods: A total of 480 foods from 16 representative Korean foods high in sodium were collected from 10 households, 10 industry foodservice establishments, and 10 Korean restaurants in four regions (Capital area, Chungcheong Province, Gyeongsang Province, and Jeolla Province) and analyzed for salinity. Results: Among the foods, stir-fried anchovies (4.07~4.45%) showed the highest salinity, followed by pickled onion (1.86~2.62%), cabbage kimchi (1.83~2.2%), braised burdock and lotus root (1.79~2.17%), and sliced radish kimchi (1.78~1.89%) (p<0.001). The salinity of kimchi from home meals (2.2%) was significantly higher than that of foodservice (1.83%) and restaurant (1.93%) kimchi (p<0.05). Salinity in each group of food was highest in kimchi (1.83~2.04%), followed by braised dishes (1.54~1.78%), steamed dishes (1.0~1.22%), stir-fried dishes (1.02~1.18%), and soup or stew (0.74~1.02%) (p<0.001). The salinity of soup and stew from restaurants (1.02%) was significantly higher than that of home meal (0.84%) and foodservice (0.74%) soup and stew. Conclusions: Determination of the salinity of representative Korean foods known to be high in sodium by eating place is expected to be useful to establishing guidelines for reduction of salinity.

In 2013, the Asian Development Bank classified the Philippines among the countries facing high food security risks. Evidence has suggested that climate change has affected agricultural productivity, and the effect of extreme climatic events notably drought has worsened each year. This had resulted in serious hydrological repercussions by limiting the timely water availability for the agriculture sector. Laguna is the 3^rd most populated province in the country, and it serves as one of the food baskets that feed the region and nearby provinces. In addition to climate change, population growth, rapid industrialization, and urban encroachment are also straining the delicate balance between water demand and supply. Studies have projected that the province will experience less rainfall and an increase in temperature, which could simultaneously affect water availability and crop yield. Hence, understanding the composite threat of climate change for crop yield and water consumption is imperative to devise mitigation plans and judicious use of water resources. The water footprint concept elaborates the water used per unit of crop yield production and it can approximate the dual impacts of climate change on water and agricultural production. In this study, the water footprint (WF) of six main crops produced in Laguna were estimated during 2010-2020 by following the methodology proposed by the Water Footprint Network. The result of this work gives importance to WF studies in a local setting which can be used as a comparison between different provinces as well as a piece of vital information to guide policy makers to adopt plans for crop-related use of water and food security in the Philippines.

During an investigation of micro-fungi in soil, two fungal isolates belonging to the phylum Ascomycota, namely KNUF-20-NI011 and KNUF-20-NI006, were collected from Gyeongbuk Province and Dokdo Island in Korea and identified as Clonostachys divergens and Chrysosporium merdarium, respectively. The fungal isolates were confirmed through molecular phylogenetic analyses of the internal transcribed spacer regions, 28S rDNA large subunit, and β-tubulin sequences. Cultural and morphological characteristics were observed and determined using different media. These species were identified based on phylogenetic relationships along with their cultural and morphological characteristics. To our knowledge, this is the first report on Clonostachys divergens and Chrysosporium merdarium in Korea.

Jindong Granites are plotted mainly in the region of granodiorite~diorite of the Streckeisen's diagram, while Yucheon-Eonyang Granites and Onjonri Granites in the region of monzo-granite and monzo-granite~granodiorite, respectively. Jindong Granites show a differenciation trend of calc-alkaline magma, and its magmatic evolution from intermediate to acidic rocks, which might form mineralizing solution, is consistant with the general path of the Cretaceous granitic rocks including Yucheon-Eonyang Granites and Onjongri Granites. The differenciation index (D.I.) is 35~80 for Jindong Granites, which is lower than 85~95 of Yucheon-Eonyang Granites and is partly overlapped by 67~84 of Onjongri Granites. There is clear difference in content of some major and trace elements between Jindong Granites of Cu province and the other granitic rocks of Pb-Zn and Mo provinces. Between these metallogenic provicnes, Cu content is high in Jindong Granites near Haman-Gunbuk mineralized zone, while Pb and Zn are relatively abundant in Yucheon-Eonyang Granites and Mo in Onjongri Granites. Therefore, Jindong Granites of the Cu province are distinguishable by chemical compositions and their related geochemical characteristics from the other Cretaceous granitic rocks of Pb-Zn and Mo provinces. However, the content of Cu and Cl in biotite is applicable to distinguish a productive phase from a barren phase of Jindong Granites, because Cu and Cl show a trend to be concentrated in biotite of Jindong Gratites in the Haman-Gunbuk mineralized zone.

경북지역에서 브랜드 쌀로써 시판되는 쌀 21종류의 품질 특성과 미질과의 관계를 분석한 결과 단백질 함량이 낮을수록 식미치는 높았고, 수분함량이 낮은 품종의 쌀로 취반 하는 경우 밥의 덩어리진 정도에 대한 기호도가 높았다. 그리고 취반 밥의 색상에 대한 기호도는 완전립의 비율이 높을수록 좋았다. 단백질의 함량이 높은 쌀로 취반하는 경우 구수한 냄새에 대한 기호도가 높았으며, 수분함량이 높은 쌀로 취반하는 경우 씹힘성에 대한 기호도는 좋았다. 그리고 아밀로오스 함량이 낮은 품종의 쌀로 취반하는 경우 씹힘성에 대한 기호도는 좋았다.

1983년 춘기 경북 중북부지방의 뽕밭에 원인불명의 발아불량현상이 발생하였던 바, 그 원인을 구명하기 위하여 대표적인 피해뽕밭을 선택 토양 및 식물체를 분석하였으며 피해지역의기온을 조사분석하여 다음과 같은 결론을 얻었다. 1. 피해상의 특징은 전혀 발아를 하지 않고 죽는 것과 발아도중 가지 선단부의 동아가 탈포기까지 피아가 갑자기 말라죽고 피부본부에 Necrosis 현상이 발생하며 심한 경우에는 가지의 기부에 Measles증상이 나타난다. 2. 유효토심은 피해뽕밭이 30cm이내, 건전뽕밭이 30-60cm이었다. 3. 토양 pH, 유기물 합량, 유효인산 및 치환성기 등은 피해뽕밭이나 건전뽕밭간에 차이가 없었다. 4. 토양내 유효붕소함량은 칠곡 및 상주 화서 뽕밭에서만 건전뽕밭이 피해뽕밭보다 유의하게 많았으며 선산 및 상주 낙동 뽕밭에서는 건전뽕밭이 피해뽕밭보다 약간 많았으나 유의차가 없었다. 5. 식물체의 붕소함량은 엽 피부 똑같이 건전뽕밭이 피해뽕밭보다 유의하게 많았다. 6. 발아불량 피해가 심하였던 뽕밭에 붕사를 첨가하여 사경재배한 뽕나무가 붕사나 붕소를 시용한 결과 토양 및 식물체내에 붕소함량이 유의하게 증가하였으며, 거의 100%에 가까운 회복률을 나타냈다. 7. 발아불량 뽕밭에 붕사를 시용한 뽕나무와 붕소를 첨가하여 사경재배한 뽕나무가 붕사나 붕소를 시용하지 않은 뽕나무보다 내동성이 강하게 나타났다. 8. 83년 하순의 이상고온이 예년보다 빨리 뽕나무의 수액을 상승시켰고 이로 인하여 발아유도가 빨랐기 때문에 4월 3일 조상최저기온이 -6.4$^{\circ}C$로 급강하하여 많은 뽕나무가 동해피해를 받았던 것 같다. 이상의 결과로 보아 83년 춘기 경북중북부지방의 뽕밭에 발생한 발아불량현상의 원인은 주인이 저온에 의한 동해라고 볼 수 있으며 지역적으로는 붕소결핍에 의한 발아불량현상도 적지 않았고 특히 붕소결핍이 동해피해를 가속화시켰다고 볼 수 있다.

The purpose of this research was develop tailored landslide hazard assessment table (LHAT) in Gyeongsangbuk-do Province and propose building strategies on environmental information system to estimate landslide hazard area according to LHAT. To accomplish this purpose, this research investigated factors occurring landslide at 172 landslide occurred sites in 23 city and county of Gyeongsangbuk-do Province and analyzed what factors effected landslide occurrence quantity using the multiple statistics of quantification method(I). The results of analysis, factors affecting landslide occurrence quantity were shown in order of slope position, slope length, bedrock, aspect, forest age, slope form and slope. And results of the development of LHAT for predict mapping of landslide-susceptible area in Gyeongsangbuk-do Province, total score range was divided that 107 under is stable area(IV class), 107~176 is area with little susceptibility to landslide(III class), 177~246 is area with moderate susceptibility to landslide(II class), above 247 area with severe susceptibility to landslide(I class). According to LHAT, this research built landslide attribute database and made 7 digital theme maps at mountainous area located in Goryeong Gun, Seongju-Gun, and Kimcheon-City. The results of prediction on degree of landslide hazard using environmental information system, area with little susceptibility to landslide(III class) occupied 65.56% and severe susceptibility to landslide(I class) occupied 0.51%.
