The fermentation process of kimchi, which is a traditional Korean food, influences the resulting compo- sition of microorganisms, such as the genera Leuconostoc, Weissella, and Lactobacillus. In addition, several factors, including the type of kimchi, fermentation conditions, materials, and ingredients, can influence the distribution of the kimchi microbial community. In this study, next-generation sequencing (NGS) of kimchi samples obtained from central (Gangwon-do and Gyeonggi-do) and southern (Jeolla-do and Gyeongsang-do) regions in Korea was performed, and the microbial communities in samples from the two regions were compared. Good's coverage prediction for all samples was higher than 99%, indicating that there was sufficient reliability for comparative analysis. However, in a α -diversity analysis, there was no significant difference in species richness and diversity between samples. The Firmicutes phylum was common in both regions. At the species level, Weissella kandleri dominated in central (46.5%) and southern (30.8%) regions. Linear discriminant analysis effect size (LEfSe) analysis was performed to identify biomarkers representing the microbial community in each region. The LEfSe results pointed to statistically significant differences between the two regions in community composition, with Leuconostocaceae (71.4%) dominating in the central region and Lactobacillaceae (61.0%) dominating in the southern region. Based on these results, it can be concluded that the microbial communities of kimchi are significantly influenced by regional properties and that it can provide more useful scientific data to study the relationship between regional characteristics of kimchi and their microbial distribution.

석회동굴의 분포는 석회암지대에 존재하기 때문에 Karst 지형의 분포와 밀접한 관계가 있다. Karst 지형은 1893년 유고슬라비아의 J.Cvijic에 의해서 Istria에서 Kotoor지역에서 최초로 보고되었다. 세계의 주요 카르스트지형의 분포지를 보면 Yugoslavia의 Karst지방 남부, France의 Causs지방, Espania의 Andalusia지방, 그 밖에 Greece와 북부 Yucatan반도, 중앙 America의 Jamaica와 Puerto Rico와 Cuba의 북부지역 그리고 북부 Great Australian Bight 부근의 해안평야, 미국의 Florida 반도의 중부와 Great Valley, Indiana 남부 Kentucky의 각지의 Tennessee 중서부, 그리고 영국의 중앙북부인 백악지방, 중국의 화남지방, Thailand, Vietnam, Burma, Celebes 남부, Java, 일본의 추길대지방과 평미대지역 등이다.(중략)

호우는 우리나라에 매년 약 60여명의 인명과 6,000억원에 달하는 재산 손실을 가져오는 가장 파괴적인 자연 재해이다. 그러므로, 강수 행태의 변화, 특히 호우 빈도와 규모의 변화를 이해하는 것은 악기상과 관련된 재해를 최소화하는데 필요한 환경영향평가에 필수적이다. 최근 기후변화의 징후로써 뿐만 아니라 사회에 미치는 영향 때문에 강수 극값에 대한 관심이 크게 증가하고 있다. 기후변화가 사회에 영향을 미치게 될 규모는 기후변동성의 변화, 특히 기후극값의 강도와 빈도에 의해서 결정 될 것이다. 본 연구의 목적은 한반도 남부지방의 장기간의 강수강도와 극값의 변화 경향을 파악하는 것이다. 장기간의 일 강수 자료(1920-1999)를 보유하고 있는 대구, 전주, 부산, 목포의 자료를 산술 평균하여 남부지방의 지역 일 강수 계열을 구축하였다. 남부지방의 연강수일수는 뚜렷한 감소현상이 나타나는 반면 연강수량은 약한 증가현상을 보인다. 이로 인해서 강수일수당 강수량을 보여주는 강수강도는 뚜렷하게 증가하고 있다. 이 모든 경향은 통계적으로 유의한 수준의 변화이다. 계절별로는 여름의 강수량 증가와 가을의 강수일 수 감소가 가장 뚜렷하다. 또한 강수극값의 규모를 나타내는 90번째, 95번째, 99번째 백분위수의 값도 증가하는 경향을 보여주고 있다. 호우 사상의 발생빈도와 그에 의한 강수량은 증가하는 반면, 비호우 사상의 발생빈도는 감소하고, 그에 의한 강수량에는 뚜렷한 경향이 나타나지 않았다. 남부지방에 나타난 강수일수의 감소는 비호우 사상의 감소에 의한 것이었고, 강수량의 증가는 호우 사상의 발생빈도와 그에 의한 강수량 증가에 의한 것 임을 알 수 있다. 위의 결과는 한반도에서도 기후변화에 의한 수문순환의 강화를 나타나고 있음을 보여주는 것으로, 기후변화에 대응하기 위한 적절한 지역영향평가를 위해서는 강수 극값에 대한 보다 상세한 분석이 필요함을 제안하고 있다.

The relationship between precipitation and groundwater level and the correlation between the moving average of precipitation and goundwater level were analyzed for the southern area of Korean peninsular. There were somewhat different patterns of seasonal fluctuation of groundwater level data. The groundwater level data tends to decrease in dry spell and increase in wet spell however the range between maximum and minimum values is quite different for each gauging point. The maximum correlation coefficient for each gauging station is obtained in a range of 20- to 130-day moving average period of precipitation. The critical infiltration, which is the maximum daily infiltration averaged throughout watershed, value is turned out to have the range of 10 to 90 mm and the moving average period is 10 to 150 days. We could have stronger correlation when we consider critical infiltration and modify the original precipitation data than we use original precipitation data.

In this study, I aimed to suggest political data on the plantation of chestnut trees given the local features by conducting an analysis on the economic efficiency of the plantation of chestnut trees aimed at chestnut tree plantation farmhouses (total 67 farmhouses) in Chungbuk, Chungnam, Jeonbuk, Jeonnam and Gyeongnam, which are the chief producing place in Korea. As a result, the central area (Chungbuk, Chungnam) was proven to post 2.7 times as many as the average total income, 3.9 times as many as income, and 12.1 times as many as net income per ha when compared with those in the southern area (Jeonnam, Gyeongnam). That is, the southern area demonstrated a very low economic efficiency on the plantation of chestnut trees compared with that of the central area, and this was caused by the reduction of chestnut production and the degradation of chestnut quality due to the aging of chestnut trees. Therefore, it is imperative to consistently renovate aged chestnut orchards and manage them in the southern area.

The ways of preservation of chotkal which are classified by the principles of fermentation, are analyzed and interpreted. Chotkal is preserved mainly as two forms; one is chot and the other is shikhae. The fact that shikhae is preserved only in the eastern area can be attributed to two main reasons; (1) raw materials are available throughout four seasons and (2) relatively less production of salt. Chotkal is further classified into nine different ways of preservation and shikhae into fourteen. Regional characteristics for chot include that (1) in western part, Kechot is preserved in salty water (2) in central part Origuljot is fermented either with salt and powdered red pepper, or with salt, powdered red pepper and cooked cereal, (3) in southern part, freshwater shrimp with (1) salt only, (2) salt and powdered red pepper, (3) salt and cooked cereal, (4) salt, powdered red pepper and cooked cereal, (4) in northern part, fish with salt and powdered red pepper. Those for shikhae include that malt is used in southern part, shredded radish in northern part and cooked cereal more in southern part than in northern part.
