유한선(Han-Sun Ryu),김희정(Heejung Kim),문진아(Jinah Moon),Naing Aung Khant 대한지질학회 2021 대한지질학회 학술대회 Vol.2021 No.10
본 연구에서는 전 세계 하나의 종만 존재하는 희귀종 물거미가 서식하고 있는 은대리 물거미서식지 일대에서 지하수-습지-지표수 상호작용에 따른 수화학적(양이온, 음이온, 알칼리도, 산소-수소 동위원소, 라돈) 특성을 분석하였다. 현장조사 지점은 은대리 물거미서식지(습지)를 중심으로 500 m 내외에 위치하고 있는 지하수 4지점, 습지 3지점, 지표수 3지점을 선정하였다. 2021년 5월부터 8월까지 총 4회 현장조사 및 시료채취를 수행하였다. 연구지역의 지하수, 습지 그리고 지표수의 수리화학특성 분석 결과 습지와 가장 근접해 있는 심부 지하수(EDG4)를 제외한 모든 지점이 Ca-HCO₃ 유형에 도시되었으며, EDG4에 경우 Na-HCO₃ 유형에 도시되어 다른 지점과 구분되었다. 산소-수소 동위원소 분석자료는 지하수, 습지 및 지표수의 물 모두 같은 기원인 것으로 보인다. 하지만 지하수와 지표수는 비슷한 동위원소 함량(δ<SUP>18</SUP>O: -8.51~–7.11‰, δD: -57.13~-49.78‰)을 가지고 있어 함께 도시되는 것을 볼 수 있었으나, 습지의 경우 지하수와 지표수에 비해 비교적 무거운 동위원소 함량(δ<SUP>18</SUP>O: -5.88~–2.13‰, δD: -41.76~-27.13‰)을 보이며 확연히 구분된 위치에 도시 되었다. 라돈의 경우 지하수, 습지 및 지표수 모두 조사를 시작한 5월에서부터 6월, 7월 점차적으로 농도가 감소하는 경향을 보였다. 지하수에서 가장 높은 라돈 농도를 보이며, 지표수의 농도가 가장 낮게 측정 되었다. 습지는 지하수와 하천수 사이의 농도 값을 보여 습지가 지하수와 지표수 모두의 영향을 받고 있을 가능성 또한 보여준다. 은대리 물거미서식지는 우리나라 유일하게 멸종위기 물거미가 서식하고 있는 의미있는 지역으로 이 일대 지하수, 습지 그리고 지표수의 수화학적 특성 연구를 통해 물거미 서식 환경에 대한 기초적인 수리생태학적 정보를 제공할 수 있을 것으로 기대한다.
Illegal Trade between India and Myanmar
Naing Naing,Kim, Chan-wahn 한국외국어대학교 인도연구소 2015 남아시아연구 Vol.20 No.3
Illegal trade, a long-standing issue in Myanmar and India, hinder the socio-economic development of the both countries. Therefore, this paper discussed illegal trade relations between India and Myanmar with special reference to its impacts on Myanmar socio-economic sectors. It was observed that Myanmar has suffered from many negative impacts, except few positive, of the illegal trade with India on their socioeconomic fronts. Illegal trade can be considered in a good way that can improve living standard of the people who involve in the illegal trade activities in Myanmar. Nevertheless, illegal trade is mostly regarded as a barrier to the socio-economic development of the country losing the government"s revenues and creating unfair competition on the market, providing a source of corruption, damaging public health and even harming for environment. It is recommended that in order to enhance formal trade cooperation and reduce illegal trade between Myanmar and India, the existing rules and procedures of trade and the range of commodities allowed to be traded in the border trade agreement should be revised and reformulated. It is said, however, that trade liberalization alone will not be able to contribute to promote trade and reduce illegal trade, if a pro-poor trade strategy is not included in the trade regimes of the countries. So, government of Myanmar has to actively engage in tackling down various problems to promote legal trade with government of India, in general and Manipur state government, in particular. If then, certainly the relations between India and Myanmar will be greatly improved. It is also good for the future prospect of sub-regional cooperation such as BIMSTEC and BCIM that bridge between South and Southeast Asian regions.

<P> The effects of supplementary lighting with high-pressure sodium (HSP) lamps alone or in combination with carbon dioxide (CO2) on the growth, yield, and flower stem quality of two rose cultivars (‘Loving Heart’ and ‘Top Grace’) were studied. Compared to natural lighting (control), supplementary lighting alone was beneficial for plant growth, and it increased plant height, stem diameter, and the number of axillary shoots. Furthermore, increases in flower stem yield (@@>@@70 cm), flower stem diameter, fresh weight, and the number of petals per flower were also observed. The combination of supplementary lighting and CO2 significantly enhanced all of the studied parameters compared to supplementary lighting alone. Moreover, stomatal density and chlorophyll fluorescence were seemingly affected by either supplementary lighting alone or in combination with CO2. This is the first study to examine the beneficial effects of combined supplementary lighting and CO2 conditions, and the resulting information is essential to rose growers and commercial production. </P>

We investigated whether ethylene is involved in the stem-bending mechanism of the two diferent gerberas [long-lived cultivar ‘Mary Queen’ and short-lived cultivar ‘Harmony’] by pretreating the stems with an ethylene-releasing compound (Ethephon), an ethylene-action inhibitor [silver thiosulfate (STS)], or Ethephon in combination with STS (Ethephon+STS), using distilled water as the control. In the cv. ‘Mary Queen,’ the control stems did not show stem bending, while the treatment groups showed bending at 6 and 9 days after treatment (DAT). In the cv. ‘Harmony,’ the bending rate observed in the Ethephon-treated stems was lower than the other treatments at 9 DAT. However, a lower bending rate in the Ethephon group relative to the other treatments is unlikely to be associated with ethylene action, because the bending rate observed in the Ethephon+STS group was signifcantly higher than the STS group. In addition, the bending rates of both cultivars were not associated with lignin contents or the expression of lignin biosynthesis genes in the stems. As it is complicated to conclude the role of Ethephon in stem bending of the gerberas, these results suggest that the use of Ethephon to delay stem bending in cut gerberas is not warranted
The Beginnings of the Sudhamma Buddhist Order of Monks
Naing, Shwe Zin Hpon Korea Institute for ASEAN Studies 2012 Suvannabhumi Vol.4 No.2
This article uncovers the beginning of the Sudhamma Buddhist order tracing its background history. After ascending the throne, being interested in trying to bring back Buddhism to its ancient strength and prosperity, King Mindon paid fully attention in all the religious affairs like King Asoka. Therefore, the different Sangha associations had emerged in his time. It had grown wider and wider and that brought about many adverse effects. During the time of King Thibaw, to reorganize the Sangha associations, he appointed two Supreme Leaders; one for Sudhamma and one for the Rhwekyan Buddhist Order of Monks. Thus the rise of the term of Sudhamma Buddhist Order of Monks became the most popular among the Theravada Buddhist monks. This article, tracing its history, will answer the question that what about any difference between the Sudhamma Buddhist Order and others especially?

Soilborne fungal phytopathogens cause significant losses in many economically important crops and vegetables. The only way to control these devastating pathogens is by using higher doses of fungicides which not only increase the cost of production but also cause significant damage to the environment. Therefore alternate control measures are always looked for. In the present study, an antagonistic strain was isolated from the soil of the pepper fields around the seashore of Jellanamdo, South Korea and identified as Paenibacillus ehimensis KWN38 based on 16S rRNA sequencing. The strain showed high antifungal activity against six tested fungal pathogens belonging to various taxonomic groups on dual culture plates. Furthermore, the strain produced volatile antimicrobial compounds which had strong fungal growth inhibitory effect. The strain also showed high chitinase, cellulase, glucanase and protease activities. The hyphal morphologies of Rhizoctonia solani AG-1 (IA), Fusarium oxysporum f.sp. lycopersici and Phytophthora capsici were significantly destroyed by the crude enzymes and butanol extract from the culture supernatant and the affected hyphae showed abnormal bending, tip curling, and irregular branching. Hence, Paenibacillus ehimensis KWN38 is considered as a potential biocontrol agent of the soil-borne fungi causing plant diseases which is an important perspective of the present study.
