  • 위마비증(gastroparesis)이나 만성 구역 구토 증후군(chronic unexplained nausea and vomiting)으로 인한 구역과 구토에 대한 치료는 일반적으로 사용하는 위장관 촉진제에 만족스럽지 못한 경우가 많고, 여러 부작용으로 인하여 장기적으로 사용하기 어려워 보다 효과적인 치료 방법이 필요하다. 최근 미국에서 발표된 본 연구는 위마비증이나 연관 증후군 환자에서 구역과 구토 증상을 줄이기 위한 aprepitant(neurokinin-1 receptor antagonist) 치료의 효과를 분석한 것으로, 향후 일반적인 치료에 불응성 위마비증 환자에서 새로운 약제 사용을 시도해볼 수 있어 소개하고자 한다. 본 Aprepitant for the Relief of Nausea (APRON) 연구는 기질적 질환을 배제하기 위하여 최근 2년 이내 위내시경이 정상이며, 적어도 6개월 이상 조기 포만감(early satiety), 식후 만복감(postprandial fullness), 팽만감(bloating) 그리고 명치부 통증(epigastric pain)을 유발하는 증상과 함께 만성적인 구역이 있는 18세 이상의 성인 중 4시간의 위배출 검사를 시행받은 환자를 대상으로 하였다. 객관적인 지표로 0점에서 45점까지 보이는 9-증상 Gastroparesis Cardinal Symptom Index(GCSI)가 2주 이상 총 21점 이상이며, 0-100 mm의 visual analog scale (VAS)의 7일간의 구역 증상 평균 25 mm 이상인 환자를 대상으로 하였다. 일주일에 3일 이상 narcotics를 사용하였거나 와파린이나 pimozide, terfenadien, astemizole, cisapride를 복용하였던 환자, 2배 이상으로 간 효소 수치상승을 보이거나 Child-Pugh score 10점 이상, aprepitant에 알레르기를 보이는 환자는 제외되었다. 그렇지만 metoclopramide나 erythromycin을 안정적으로 사용 중인 환자는 제외되지 않았다. 위배출 검사는 2시간에서 60% 이상 남아 있거나 4시간에서 10% 이상 남아 있는 경우에 지연된 것으로 정의되었으며, 지연된 위배출 검사 결과 자체는 환자의 등록 기준에 포함되진 않았다. 등록 기준에 포함된 환자는 1:1로 무작위 배정되어 하루 한 번 125 mg의 aprepitant 복용군과 위약군으로 나누어져 연구가 진행되었으며, 약제 복용 4주간 2주 간격으로, 그리고 복용 후 2주 뒤까지 구역 증상의 호전 정도와 약제 안전성을 확인하였다. 이러한 효과를 판정하기 위하여 환자가 방문하는 동안 GCSI를 포함한 Patient Assessment of Upper GI Symptoms (PAGI-SYM), Gastrointestinal Symptom Rating Scale, daily VAS, daily diary version of the GCSI 그리고 정신 측정 도구와 삶의 질 도구인 Patient health Questionnaire 15와 Short Form 36 version이 측정되었다. 구역에 대한 aprepitant와 위약의 치료 효과의 일차적 판정은 이전 항암 요법에 대한 aprepitant 연구와 같이 28일 평균 VAS 25 mm 미만이거나 치료 전 7일간의 VAS와 비교하여 28일 치료 기간 동안 25 mm 이상 감소한 경우로 정의하였고, 이차 결과는 구역의 매일 시간, 치료 중 구역이 없는 날짜의 퍼센트, PAGI-SYM score의 개선 등으로 확인하였다. 2013년 4월부터 2015년 7월까지 총 126명의 환자가 등록되어 aprepitant군 63명, 위약군 63명으로 무작위 배정되었다. 전체의 57%인 72명에서 위배출 지연이 보였으며, 나머지 43%에서는 정상 또는 빠른 위배출 소견을 보여 만성적으로 설명할 수 없는 구역과 구토에 포함된 환자군으로 확인되었다. 또한 29%에서 당뇨를 가지고 있었으며, 8%에서 수면제를 사용하고 있었다. 최종적으로 aprepitant군은 59명, 위약군은 63명이 연구를 끝까지 종료하였다. 일차 결과에서 aprepitant 군 46%, 위약군 40%의 구역 호전을 보여 두 치료군 간에 통계적으로 의미 있는 차이는 보이지 않았다(상대 위험도 1.2, 95% CI: 0.8-1.7; p=0.43). 그러나 일차 분석의 두 가지 척도(28일 평균 VAS 25 mm 미만과 기저 VAS보다 평균 28일 VAS의 25 mm 이상 감소)를 모두 함께 고려한 민감도 분석에서는 aprepitant군이 37% (22/59)로 위약군의 17%(11/63)에 비하여 통계적으로 의미 있는 구역의 호전을 보였다(상대 위험도 2.1, 95% CI: 1.1-4.1; p=0.01). 또한 이차 분석을 살펴보면 aprepitant군에서 PAGI-SYM 중증도 지수로 확인하였을 때, 구역(1.8 vs. 1.0; p=0.005)과 구토(1.6 vs. 0.5; p=0.001)의 중증도 및 매일 구역 시간의 감소를 보였고, 28일 동안 구역이 없는 날짜의 퍼센트 증가 소견을 보였다. 다른 이차 결과 분석에서 aprepitant군이 PAGI-SYM 중증도 지수의 GCSI 종합 점수(1.3 vs. 0.7; p=0.001), 상당한 증상호전, 구역 구토의 세부 점수, 팽만감 세부 점수 그리고 위식도 역류 증상 점수에서 호전을 보였고, 매일 일기로 표현한 daily diary version of the GCSI에 상복부 통증 중증도, 전체 증상 그리고 Gastrointestinal Symptom Rating Scale의 종합 점수에서 호전을 보였다. 연구 중 발생한 부작용은 주로 경증과 중등도 정도의 부작용이 주로 발생하였지만, aprepitant군(35% vs. 17% 위약군, p=0.04)에서 더 많이 발생하였다. 결론적으로 위마비증 또는 위마비증 유사 증후군으로 인한 만성 구역 및 구토 환자의 무작위 시험에서 aprepitant는 VAS 점수를 통한 주요 결과를 분석하였을 때는 구역의 중증도를 호전시키지 못하였지만 다른 이차적 결과에 대해서는 위약군에 대하여 호전 소견을 보였다. 따라서 aprepitant에 효과적인 반응을 보이는 위마비증 환자를 감별하는 추가 임상시험이 필요할 것으로 판단된다.

  • This study purported to investigate the current state of human rights of older adults residing in rural areas of Korea. The study utilized, as an analytic framework, 4 priority directions (1. "older persons and development", 2. "rural area development", 3. "advancing health and well-being into old age", and 4. "ensuring enabling and supportive environments") with 13 task actions recommended by Madrid International Plan of Action on Ageing (MIPAA). Furthermore, the study examined gender differences in all items included in the analytic framework. Data was collected by the face-to-face survey on 800 subjects aged 65 and over. Statistical analyses were conducted using STATA 13.0 program. The main results were summarized in order of 4 priority directions as follows. First, average working hours per day were 6.2, and men reportedly participated in economic activities and needed job training more than women, while women participated in lifelong education programs more than men. Awareness of fire and disaster prevention facilities was low in both genders. Second, accessibility to the support center for the elderly living alone as well as protective services for the vulnerable elderly was found to be low. IT-based services and networking were used more by men than women, and specifically, IT-based financial transactions and welfare services were least used. Third, medical check-ups and vaccinations were well received, while consistent treatments for chronic illnesses and long-term care services were relatively less given. In addition, accessibility to mental health service centers was considerably low. Fourth, although old house structures and the lack of convenience facilities were found to be circumstantial risk factors for these elders, experiences of receiving housing support services were scarce. The elderly were found to rely more on informal care, and concerns for their care were higher in women than men. Plus, accessibility to elderly abuse services was markedly low. Based on these results, discussed were implications for implementing policies and practical interventions to raise the levels of the human rights for this population.

  • A newly developed rice variety "Pungmi 1" is a japonica rice(Oryza sativa L.) with high grain quality and multi-resistant to diseases. It was developed by the rice breeding team of Yeongnam Agricultural Research Institute (YARI), RDA. in 2004. This variety derived from a cross between "YR13616Acp 1", having short culm and multi-resistance to biotic stresses and "Milyang 122" with good grain quality. It has short stature of 73cm in culm length and mid-early flowering date of Aug. 13. This variety is moderately resistant to leaf blast showing durable resistance of lower 10% diseased leaf araea in sequential planting meothod. Milled rice kernel of "Pungmi 1" is translucent, clear in chalkness and good at eating quality in panel test. Milling recovery and head rice ratios were comparable to Milyang 122, while it has low protein content. The milled rice yield potential of "Pungmi 1" is about 5.59 MT/ha at ordinary fertilizer level of local adaptability test. This cultivar would be adaptable to Yeongnam inland plains and southern coastal areas of Yeongnam province at ordinary transplanting as well as after barly cultivation.

  • This study was carried out to fortify the antimicrobial activity of yoghurt by adding liquorice extract to it. The liquorice extracts (1 mg/mL) showed relatively high antibacterial activity against H. pylori KCCM 40449 (p < 0.05). The solvent liquorice extracts of minimal inhibitory concentrations (MIC) against H. pylori KCCM 40449 were 25- 100 ${\mu}g$/mL. Lactobacillus amylovorus DU-21 with high EPS production ability were inoulated to milk after the addition of different amounts of liquorice extracts (0.0%, 0.05%, 0.1% and 0.2%). The physico-chemical characteristics of yoghurts added with liquorice extracts were examined. The initial pH, titratable acidity, viscosity and viable cell counts of the yoghurt added liquorice extracts were 3.41-3.51, 1.021-1.091%, 1,686-1,930 cp and 9.41-9.38 Log CFU/mL, respectively. The viscosity and syneresis of yoghurt were better than that of the control. Antimicrobial activity against H. pylori KCCM 40449 increased with increasing addition of liquorice extract. However, the sensory score of yoghurt added with different amounts of liquorice extracts was lower than that of the control (p < 0.05). As a result of the sensory evaluations, the flavor, taste, texture, color and overall acceptability of the yoghurt with 0.05% liquorice extract were found to be much better than those of the other groups (p < 0.05). Overall, the optimal amount of liquorice extract added in the manufacture of yoghurt was 0.05% of the total weight. Further studies on increment of antimicrobial activity and palatability of liquorice extract added yoghurt are necessary.

  • The main objective of this study was to develop the multi-resistance lines to insects(brown planthopper; BPH, rice green leafhopper; GRH) and disease(blast; BL, bacterial blight; BB and rice stripe virus disease;RSV) with good grain quality and plant type by combining conventional breeding and marker assisted selection(MAS) and to eliminate the linkage drag effects between Bph1 gene and culm length, we conducted MAS of Bph1 gene in advanced backcross and double cross progenies. 'Nampyeong', 'Junam' and 'Milyang220' were used as the parent in this study. 'Milyang220' was used as the donor of brown planthopper resistance gene Bph1 with tall culm length. Two backcross progenies were developed using two recipients 'Nampyeong' carrying GRH resistance gene Grh3(t) with good grain appearance and 'Junam' harboring bacterial blight resistance gene Xa3 with short culm length. Two $BC_1$ generations were resulted from the backcrossing of the $F_1$ plants with recurrent parents 'Nampyeong' and 'Junam'. The second rounds of backcrossing($BC_2$) were derived from the cross of selected resistant $BC_1F_1$ plants based on heterozygous genotype of RM28493 linked to Bph1 gene. The double crossed population was constructed from the cross of between each heterozygous $BC_2F_1$ plants at RM28493 locus of '$Nampyeong^*3$ / Milyang220' and '$Junam^*3$ / Milyang220'., The homozygous alleles in Bph1 gene were selected using co-dominant DNA marker RM28493 in double crossed population. Eighty-five lines with multi-resistance to BL, BB, RSV, GRH and BPH were selected by bio-assay and MAS in generation of double crossing. The culm length, head rice ratio and yield of the selected multi resistance lines was ranged from 71 to 88 cm, from 51 to 93%, from 449 to 629 kg/10a. respectively. We can select a promising multi resistance line similar with 'Nampyeong' of major agronomic traits such as culm legnth, head rice ratio and yield. It was designated as Milyang265. Finally this study was developed the multi resistant varieties against to insects and diseases with the good grain quality 'Milyang265' by the advanced backcross and double cross combining MAS and it can be used as genetic resources of multi-resistance to insect and diseases in rice breeding programs.

  • Purpose: This study examined the relationship between caffeine intake and metabolic syndrome in Korean adults using the 2013 ~ 2016 Korea National Health and Nutrition Examination Survey data (KNHANES). Methods: The caffeine database (DB) developed by Food and Drug Safety Assessment Agency in 2014 was used to estimate the caffeine consumption. The food and beverage consumption of the 24 hr recall data of 2013 ~ 2016 KNHANES were matched to items in the caffeine DB and the daily caffeine intakes of the individuals were calculated. The sample was limited to non-pregnant healthy adults aged 19 years and older, who were not taking any medication for disease treatment. Results: The average daily caffeine intake was 41.97 mg, and the daily intake of caffeine of 97% of the participants was from coffee, teas, soft drinks, and other beverages. Multivariate analysis showed that the caffeine intake did not affect metabolic syndrome, hypertension, low HDL-cholesterol, and abdominal obesity. Diabetes and hypertriglyceridemia, however, were 0.76 (95% CI: 0.63 ~ 0.93), and 0.87 (95% CI: 0.77 ~ 0.98) in third quintile (Q3), and 0.66 (95% CI: 0.53 ~ 0.82) and 0.83 (95% CI: 0.73 ~ 0.94) in fourth quintile (Q4) compared to Q1, respectively. Therefore, caffeine intake of 3.66 ~ 45.81 mg per day is related to a lower risk of diabetes and hypertriglyceridemia. Conclusion: The study showed that adequate caffeine intake (approximately 45 mg) was associated with a lower prevalence of diabetes and hypertriglyceridemia. Therefore, it can be used as a guideline for the adequate level of caffeine intake for maintaining health.

  • This study was conducted to investigate the factors associated with electronic cigarette use by Korean adults. To accomplish this, data collected from 228,477 individuals during a community health survey conducted by the Korean Centers for Disease Control and Prevention in 2015 were analyzed by descriptive analysis, the Chi-squared test, and logistic regression analysis. The lifetime prevalence of electronic cigarette smoking was 11.1% for men and 0.8% for women. The current prevalence for electronic cigarettes smoking was 24.2% for men and 26.1% for women among lifetime users of electronic cigarettes. The lifetime experience rate of electronic cigarette smoking was significantly associated with age, educational attainment, occupation, income status and current smoking status, respectively. The current universal smoking e-cigarette is significantly related to the current smoking status, which shows a significantly higher number of current smokers than groups that have smoked in the past. The preference for electronic cigarette smoking was high. E-cigarettes were perceived by those who aimed to quit smoking as having a smoking cessation effect compared to regular cigarettes while also providing the pleasure of smoking and addressing the addiction. Therefore, e-cigarettes were highly favored because they were reflected as a solution to the dilemma of smoking. In 2014, electronic cigarette imports tripled from the previous year, and interest in electronic cigarettes is increasing worldwide. Accordingly, measures related to the prevention and discontinuation of e-cigarettes should be considered. Strengthening anti-smoking education and active promotion of anti-smoking risks is needed to improve smokers' wrong perception of smoking-related health. The WHO also reports that there is a lack of grounds to ensure or acknowledge that e-cigarettes are effective. Accordingly, it is important to identify environmental factors influencing the use of electronic cigarettes and explore the relationship between electronic cigarette recognition and use.

  • This study aimed to provide new interpretations of the ceramics excavated from the archaeological site of the royal palace of Goryeo (918~1392), where only limited access was permitted due to its location in Gaeseong, North Korea. The interpretations were based on the existing understanding of the arrangement of the palace buildings at the site and historical records. The study of the general aspects of the celadons discovered during eight excavations at the Goryeo Palace site in Gaeseong revealed that most of the vessels found at the site were produced during the early and middle phases of the Goryeo dynasty. The study involved classifying the celadons bearing inscribed texts and symbols into 18 different types according to their characteristic features and periods of production. The inscribed celadons have provided detailed information of the site where they were found, thereby making it possible to make strong presumptions about the date of construction, function, and status of the building in the palace connected with the discoveries. The excavations from the Goryeo Palace site and related historical literature suggest that the celadons bearing the inscription "Sojeon (燒錢)" were used during the first half of the 13th century, although the existing view had been that they were used during the second half of the century. This new conclusion is based on the use of the symbols ${\circ}$ and ${\odot}$, the celadons found together with the Sojeon-inscribed celadons, the date of the celadons bearing the inscription "Seong (成)," and the location of their discovery behind the site of Seongyeongjeon (aka Hoegyeongjeon) Hall, which had been one of the main palace buildings. The Taoist rituals performed for the safety of the Goryeo dynasty were largely held at Ganganjeon (aka Daegwanjeon) Hall in the western part of the royal palace during the second half of the 13th century. It was mostly in the first half of the 13th century just before the transfer of the Goryeo government from Gaeseong to Ganghwa (1232~1270) that the Taoist rituals were held at the location near Seongyeongjeon Hall, where archaeologists found the Sojeon-inscribed celadons. Therefore, the large number of celadon cups with holders, including those inscribed with Sojeon, discovered during the eighth excavation of the palace site suggests that they were used for the rituals held at Seongyeongjeon Hall during the first half of the 13th century.
