The graft cactus (Gymnocalycium mihanovichii) continues to be exported to more than 20 countries worldwide. In April 2021, typical bacterial symptoms of soft rot were observed in the graft cactus (cv. Yeonbit) in Goyang, Gyeonggi-do, Korea, resulting in economic losses in cactus production. The stems turned dark brown and the flowers were covered with black rot. The bacterial strain designated as KNUB-01-21 was isolated from infected stems and flowers. The results of the morphological and biochemical tests of the isolate were similar to those of Pectobacterium brasiliense. For molecular analysis, the 16S rRNA region and three housekeeping genes (dnaX, leuS, and recA) of the strain KNUB-01-21 were amplified. Based on the results of the molecular analysis and morphological and biochemical tests, KNUB-01-21 was identified as P. brasiliense. The pathogenicity of KNUB-01-21 on graft cactus was confirmed by an inoculation test. Artificial inoculation using P. brasiliense KNUB-01-21 produced soft rot symptoms on the grafted cactus, and the same bacterium was re-isolated and re-identified. This is the first report of P. brasiliense causing soft rot in graft cactus in Korea.

This is a nonequivalent control group non-synchronized experiment research to verify the effect of moxibustion therapy on efficient management of daily living disabilities and sleep patterns in elderly women with chronic low back pain. Total 12 sessions of moxibustion therapy were applied to elderly women(30 subjects in an experimental group and 30 subjects in a control group) in G City once a week for 12 weeks from March 15th to May $31^{st}$ 2015. Then the follow-up study was conducted 2 weeks after the post survey. For moxibustion, was applied to Shen-shu, Ashi point, Ta chang shu, Yang kuan and Yosu. 5 sheets of moxibustion were applied to 7 acupuncture points of Mugeukboyang moxibustion; Zu san li & Chu chi, Chung wan, Chung chi & Shui tao, Fei shu, Kao hung and Tien shu, Wijung respectively and experimental treatment was conducted. For assessing the degree of back pain, Visual Analog Scale(VAS) developed by Scott & Huskisson(1979) was used and for measuring the degree of daily living disability, Oswestry Disability Index, which was developed by Fairbank et al(1980) and translated and revised by Yim, Hyeon-sul et al.(1998), was used. For measuring sleep patterns, the sleep pattern measurement tool developed by Oh, Jin-su, Song, Mi-soon and Kim, Sin-mi(1998) was used. For data analysis, SPSS/WIN 18.0 was employed and Chi-square test, t-test and repeated measures ANOVA were performed. There were significant differences in pain score(F=2510.32, p<.001), daily living disability score(F=1937.82, p<.001) and sleep pattern score((F=15.54, p<.001) of elderly women that were provided with moxibustion therapy, compared to the control group. Therefore, it was found that moxibustion therapy made a positive contribution to reduction in pain and daily living disabilities and improvement in sleep quality. Based on this study finding, there is a need to apply moxibustion therapy to elderly people with chronic low back pain as a nursing intervention in future.

This paper deals with the historical geography of land-use and agriculture along the Lower Nam-River floodplains. The reclamation process of the river floodplains, the cultivation methods on the reclaimed lands, and the land-use patterns and processes are investigated. The Nam River, one of the major tributaries of the Nakdong River, flows through the boundary between Ham-An and Eu-Ryong Guns. Larger floodplains are located in Ham-An Gun. The floodplains of Ham-An Gun have been surveyed intensively in this study. In South Korea, the alluvial plains, mostly located along the river valleys, have been reclaimed to provide fertile agricultural lands. Those along the upper river valleys were reclaimed before those along the lower river valleys. The flood-plains of Han-An Gun were reclaimed to be the largest agricultural lands of the Gun. The natural levees along the Lower Nam-River Valley were identified before the reclamation processes but now hardly identified. Relatively larger floodplains are located along the tributary streams of the Nam River. Often there are low-lying back swamps between the natural levees and the hills/mountains that rise above the floodplains. The back swamps, called 'natural bog lands' in this region, have been reduced in size and in number through reclamation for the purpose of agricultural and industrial land-uses. Now about ten 'natural bog lands' are found in the Ham-An floodplains, and some of them are being reclaimed for the industrial land-use. This study suggests the emergent need of conservation for the remaining 'natural bog lands' in terms of ecology. Seven agricultural fields of large size, originated from the Nam-River floodplains, are identified in this study: Kun(큰들), Chung-Am(정암들), Chang-chi(장지들), Baek-San(백산들), Ha-Ki(하기들), Gu-Hae(구혜들), and Chang-Po(장포들) fields. The Kun field was reclaimed during the Japanese control and the Gu-Hae, in the 1950s. All of those except the above two fields were reclaimed after the mid-1960s. The Nam-River Dam in Chinju, completed in 1969, contributed the reclamation processes along the Lower Nam-River floodplains. The rice acreage of the region has been reduced slowly since 1970 but the rice production of the region has been relatively stable (Table 4). Rice culture had been the most important agriculture on the reclaimed lands for decades before the greenhouse vegetable cultivation became more important in the 1980s. Among the vegetables cultivated in the greenhouse, the watermelon is the dominantly leading one. Watermelons are usually harvested two or three times in a year though it is possible to harvest four times in one year. The rotation of watermelons and rice is common in the region. It is known the physical conditions of the Nam-River floodplains in Ham-An Gun is the most suitable for watermelon cultivation in South Korea.

1. Objectives This paper was tried to find out the clinical use of Gwanjung-tang by comparing patients' chief complain and natural symptom. 2. Methods The study was researched as clinically with medical records of 88 patients who visited a certain oriental medicine clinic which is in Seoul during January, 2000 and June, 2006. 3. Results 1) The male patient who was treated with Gwanjung-tang(寬中湯) is rare. The rate of patients who visited clinic in her forties is 27.3%, in fifties is 18.2%, in thirties is 15.9%, in sixties is 12.5%, in twenties is 10.3%. 2) Chief complain which made patients to visit clinic is a chest pain(19.3%), back pain and shoulder pain (15.9%), edema (12.5%), headache (9.1%), irregular menstruation (8.0%), dyspepsia (8.0%), fatigue (8.0%), insomnia (5.6%), menopausal disorder (4.5%), lumbago (4.5%), abnormal condition of stools (2.3%), and abnormal condition of urine (2.3%). 3) Natural symptom is classified into appetite, digestion, stools, urine, sweat, and sleep. The rate of patients who complained abnormal condition of digestion is 71.6%, of sleep is 59%, of stools is 52.3%, of urine is 47.7%, if sweat is 34.1%, and of appetite is 30.7%. 4) The rate of patients who is treated with Gwanjung-tang between thirty and forty packs is 43.2%, twenty packs is 39.7%, between fifty and sixty packs is 5.7%, between seventy and eighty packs is 2.3%, and between ninety and hundred packs is 3.4%. 5) The rate of patients who is treated with Gwanjung-tang during 15 days is 45.5%, between 16 and 30 days is 26.2%, between 31 and 60 days 7.9%, between 61 and 90 days 3.4%, between 91 and 120 days is 4.5%, and more than 120 days is 12.5%. 6) There are not many cases that chief complain was abnormal condition of digestion (8.0%), sleep (5.6%) stools (2.3%), and urine (2.3%). But the rate of patients who complained discomfort of digestion(71.6%), sleep(59%) stools (52.3%), and urine (47.7%) is significantly high. 7) According to "Sasang Sin Pyeon", Gwanjung-tang was used in To-sa-gwak-ran (吐瀉藿亂), Hae-su (咳嗽), Jeok-chui (積聚), Pyo-han -bu-jong (表寒浮腫), Chang-man (脹滿), Chil-gi (七氣), Dam-um (痰飮), Dam-goe (痰塊), Seom-jwa-yo-tong (閃挫腰痛), Bi-tong (臂痛) of Soeumin, and it is corresponds with clinical cases for various components. 4. Conclusions Gwanjung-tang is a medicine of reconciliation, and it makes Stomach to be warm and take down Yin Qi. The most important effect of Gwanjung-tang is Sun-qi(順氣). So it is considerable that Gyejibanhasenggang-tang (少陰人 桂枝半夏生薑湯), Hyangsayangwi-tang (少陰人 香砂養胃湯), and Gwakhyangjunggi-san (少陰人 藿香正氣散) is also effective to symptoms above, because these are medicines of reconciliatio.
