양하(Zingiber mioga Roscoe) 근경의 에탄을 추출물을 재료로 Staphylococcus aureus, Bacillus subtilis 및 B. cereus에 대한 activity-guided fractionation을 실시하여 항균성 물질 세가지준 얻었다. 항균력실험 결과, 화합물 I과 111은 세가지균주 모두에 활성이 있었고, 화합물 II에서는 B. subtilis과 B. cereus에서만 활성이 나타났다. 그 중에서 가장 활성이 강한 화합물 I을 Bioscreen C로 optical density(600 nm)를 측정하여 증식억제실험을 한 결과 10 ppm 처리시 B. subtilis과 B. cereus에서 72시간동안 강한 증식억제효과를 나타내었으며, S. aureus에서는 25 ppm 처리시 72시간동안 완전증식억제효과를 나타내었다. $1^H-NMR$, ${13}^C-NMR$, DEPT,$1^H-1^H$ COSY, HMQC, HMBC 및 IR 스펙트럼 등을 분석한 결과 화합물 I, II, III은 labdane-type diterpene인 $(E)-8{\beta}(17)-epoxylabd-12-ene-15,16-dial(C_{20}H_{30}O_3,\;MW=318)$, $galanolactone(C_{20}H_{30}O_3,\;MW=318)$ 그리고 galanal A($C_{20}H_{30}O_3,\;MW=318$)로 각각 동정되었으며, 이들은 양하의 근경에서는 처음 분리된 것이다. In order to isolate antibacterial substances from the rhizome of Zingiber mioga Roscoe, the ethanol extracts was fractionated according to the activity against Bacillus subtilis, B. cereus and Staphylococcus aureus. Three antibacterial substances were isolated and purified by column chromatography and recrystallization. Compounds I and III showed activity against all the tested bacterias and compound II exhibited the activity against B. subtilis and B. cereus S. aureus. Compound I was examined antimicrobial activity against B. subtilis, B. cereus and S. aureus by optical density using Bioscreen C. Compound I showed strong growth inhibition at 10 ppm on B. subtilis and B. cereus for 72 hrs, and at 25 ppm on S. aureus. On the basis of spectrometric studies including $1^H-NMR$, ${13}^C-NMR$, DEPT, IH-lH COSY, HMQC, HMBC and IR, compounds I, II and III were identified as $(E)-8{\beta}(17)-epoxylabd-12-ene-15,16-dial\;(C_{20}H_{30}O_3,\;MW=318)$, galanolactone $(C_{20}H_{30}O_3\;MW=318)$ and galanal A $(C_{20}H_{30}O_3,\;MW=318)$, respectively. These results are the first reports on the isolation of $(E)-8{\beta}(17)-epoxylabd-12-ene-15,16-dial, galanolactone and galanal A from the rhizome of Zingiber mioga.

Objectives : Since prostitution is multitraumatic phenomena, it is known that most women in prostitution have symptoms of posttraumatic stress disorder (PTSD) and other mental illness. In Korea, new anti-prostitution law launched in the year of 2004 imposes protecting prostituted victims at government-supported shelter. The objective of this study was to compare the mental symptoms, especially PTSD features of women who escaped from prostitution with those of control subjects. Methods : We assessed 113 ex-prostituted women who live in shelter for 8 months on the average and 65 normal control subjects. Demographic data, questionnaire for sleep, physical illness, smoking, alcohol and drug use, Stress Response Inventory, Davidson Trauma Scale (DTS), Impact of Event Scale-Revised (IES-R) were used. Results : Ex-prostituted women had significantly higher scores of DTS, IES-R, stress related responses, sleep problems, smoking problems, and alcohol problems than control group. Age and duration of sex trade of the subjects were significantly correlated with the severity or frequency of PTSD symptoms. The degree of smoking, alcohol drinking and sleep problems were also significantly correlated with the PTSD symptoms. Conclusion : These results suggested mental symptoms did not disappear even after women escaped from prostitution.

‘Sweet Gold’ is a new promising kiwifruit variety developed for high soluble solid content and firmness at the Research Institute of Climate Change and Agriculture, National Institute of Horticultural and Herbal Science, Rural Development Administration, Korea, in 2010. This variety was selected from seeds obtained by the cross between Actinidia chinensis ‘First Emperor’ and A. chinensis ‘Okcheon’ in 2000. Seedling and line selections were conducted from 2001 to 2008, and characteristic trials were carried out from 2009 to 2010. Shoots of ‘Sweet Gold’ sprouts were similar to those of ‘Jecy Gold’ with green leaves. The fruit shape was oblong and fruit skin color was yellow brown without hair. The average fruit weight was 88.7 ±12.37 g. The fruit had a central soft core, yellow or yellow green pericarp, and fragile and juicy flesh. The soluble solid content was higher than that of ‘Jecy Gold’ at 16.3° Brix when ripe and the firmness was higher, at 21.4N, than that of ‘Jecy Gold’. The harvesting time was about 7 days earlier than that of ‘Jecy Gold’. ‘Sweet Gold’ was officially registered as a new cultivar in 2014 in accordance with the Plant Variety Protection Act by the Commissioner of the KSVS (Grant Number 5151).
