  • In Southern Vietnam, the competition among Inland Clearance Depot (ICD) has resulted in deconcentration tendencies and shifting share situations. However, related research on Southern Vietnam ICDs in particular and ICDs in Vietnam in general has been extremely limited. Hence, In this study, empirical research is conducted on ICDs located in southern Vietnam from 2010 to 2017. The throughput volume data of ICDs is analyzed by concentration indicators, namely the concentration ratio (CR), the Herfindahl-Hirschman Index (HHI), the Gini coefficient, the Lorenz curve, and the shift share analysis (SSA). The results of adopting all the methodologies indicate that deconcentration was the mainstream trend for ICDs in Southern Vietnam during the period of 2010-2017. The findings provide insights into the process of container terminal development and have academic and managerial implications. The strengthening of the competitiveness of Vietnamese container ports and ICDs could affect the competing Southeast Asian neighbors by facilitating the port of more shipping companies.

  • 본 연구의 목적은 동해 울릉분지 천부퇴적층의 공극수와 메탄의 특징 및 상호작용을 규명하는데 있다. 울릉분지에서 채취한 코어에서 공극수를 추출하여 분석한 결과, 공극수의 황산염 농도가 퇴적물의 심도가 증가할수록 감소하며, 감소하는 경향은 크게 세 가지 (직선성, concave down, upward kink)로 나뉨을 알 수 있었다. 이는 모든 코어에서 황산염 환원작용이 일어나고 있음을 지시한다 황산염 농도의 수직적 구배를 이용하여 SMI (sulfate-methane interface) 심도를 계산하면, 남부울릉분지가 북부울릉분지보다 낮은 값을 갖는다. 반면에 메탄 농도는 퇴적물의 심도가 증가할수록 전반적으로 증가하며, 공간적으로는 남부 울릉분지가 북부울릉보지보다 높다. 또한 남부울릉분지에서 메탄가스 농도는 SMI 심도 아래에서 급격히 증가한다 메탄가스의 탄소 안정동위원소$(\delta^{13}C)$ 분석 값들은 대부분 $-60\%_{\circ}$이하로서 이는 메탄가스가 열기원 보다는 박테리아기원임을 지시해준다 또한 남부 울릉분지에서 메탄의 탄소 안정동위원소 분석 값들은 메탄농도가 증가할수록 낮은 값을 보여 주는 데 이러한 결과들은 남부 울릉분지에서 무산소 메탄 산화작용이 일어나고 있음을 지시하고, 메탄의 상향 분산 (diffusion)량이 북부 울릉분지보다 많이 일어난다는 것을 의미한다. 공극수내 황산염 이온 농도 구배와 메탄가스 농도를 종합적으로 고려할 때, 울릉분지에서 가스하이드레이트의 부존가능성은 북부 울룽분지보다 남부 울릉분지가 높은 것으로 추정된다.

  • The antebellum American South has been characterized by the lingering backward images of plantation, slaves and cotton. The South specializing in the cotton cultivation is compared with the manufacturing East and the breadbasket Midwest. Douglass North who examined the interregional trade assumed that the South up until 1860 relied on the Midwest for the foodstuffs. Statistical and literary evidence, however, disputes the North's model, showing instead that the southern region attained self-sufficiency in foodstuffs at least in the late 1830s or early 1840s. The South's food self-sufficiency is attributable, to a greater extent, to the region-wide environmental movement of scientific agriculture launched to address the aggravating soil problems from cotton monoculture. Diversification and crop rotation lied in the center of the new regime. The new agricultural system combining com, cotton and cowpea ensured the procurement of hoecake, hog meat, and cotton. The most significant outcome of the good farming regime, however, was the enhanced environmental consciousness which came to prevail the best farmer's reckless rush for profit maximization.

  • 콩은 중요한 식량 작물로 단백질, 기름 및 이차대사산물인 이소플라본을 다량으로 함유하고 있다. 이소플라본은 폴리페놀의 일종으로 일부 암을 예방하며 심혈관 질환을 완화하는 데에도 도움을 준다고 알려져 있다. 콩에 인위적으로 식물호르몬인 ABA를 처리할 때 이차대사산물인 kaempferol의 함량이 증가한다고 보고 되었다. 따라서 이 연구는 식물 생장조정제 처리가 콩잎의 이소플라본 함량에 미치는 영향을 알아보기 위해 수행되었다. 연구는 밀양 남부작물부 유리온실에서 수행되었으며, 콩(품종:선풍)은 와그너포트 1/2000에 1주 2본 파종하여 재배하였다. Ethephone(500, 1000, 2000 ppm)과 ABA(100, 200, 400 ppm)를 사용하였으며 각각 R2, R5, R7기에 처리하였다. 처리 후 잎을 5일 간격으로 3회 채취하여 이소플라본 6종과 쿠메스트롤의 함량을 분석하였다. 초고성능 액체 크로마토그래피(Acquity UPLC H-Class system, Waters)를 사용하여 분석하였다. 이소플라본 함량은 R5 단계에서 전반적으로 높게 나타났으며, R2 및 R7 단계에서는 무처리와 유사한 수준을 보였다. ABA를 처리하였을 때 생장조정제 간의 차이가 에테폰보다 더 큰 것으로 나타났다. 쿠메스트롤 함량은 처리시간에 따라 R7, R5, R2 순으로 높은 것으로 확인되었으며, 처리시간이 지날수록 함량이 증가함을 알 수 있었다. 생장조정제 처리에 쿠메스트롤 함량은 ABA보다 에세폰 처리 시 더 높은 경향을 보였다.

  • The present study investigated the quality characteristics of Perilla frutescens Britt. seed compounds according to the cultivar and sowing dates. In the present experiment, five Perilla cultivars, namely 'Dayu', 'Deulsaem', 'Deulhyang', 'Baekjin', 'Sodam', were planted on three different dates, including May 30, June 20, and July 10. The contents of key compounds and phenols varied depending on the cultivar and sowing date. With the delayed sowing time, the days to flowering and maturity of the culitvar decreased, while the seed weight and hardness increased. Crude protein content increased but crude lipid content decreased with the delay in the sowing time. However, there was no interaction of different sowing dates with the fatty acid content, which remained stable compared with the other values. Overall, the total polyphenol content was higher in Perilla seeds sown on May 30.

  • Proso millet (Pacnicum miliaceum L.) has a various of functional substances, so the demand is increasing as interest in human health benefits. In particular, miliacin, a triterpenoid in proso millet, is known to be effective in hair loss due to its promoting metabolism and proliferation of keratinocytes and showing protective effects from apoptosis. In this study, proso millet oil was extracted and analyzed by GC/MS using the extraction method of unsaponifiable substances after saponification reaction. The components of proso millet oil were confirmed through qualitative analysis by GC/MS. The miliacin content of 5 varieties of proso millet and 2 varieties of foxtail for comparison was analyzed. In the result, components of pentacyclic triterpenes such as β-amyrine and lupeol were detected in proso millet, and the content of miliacin was highest in Hallachal at 370.38±0.04 ㎍/100 mg oil. In addition, the content of miliacin was not detected in Samdachal and Samdamae, which are varieties of foxtail millet.

  • 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.
