The community structure and dynamic analysis of shrub forest were determined at sixty-nine stands randomly selected on the Mt. Kyeryong. The shrub forest of the Mt. Kyeryong was found to be composed of Lespedeza-Weigela community and Stephanandra-Palura community through ordination method. Species groups were determined among fourty-five main species which were selected through Klapp's method. There were Stephandra-Palura species group composed of thirty species and Lespedeza-Weigela species group of fifteen species. The succession of shrub forest was determined by using species ordination method. It was assumed that there were two main succession types ; the one from Sapium community and Sasamorpha community to Lespedeze-weigela community and the other from Parthenocissus community and Acer community to Stephanandra-Palura community.

The aim of this study was to assess how nutrient intakes are related to risk factors for metabolic syndrome according to dietary patterns in the middle-aged adults. Methods: The subjects (n = 187; 47 men, 140 women) consisted of middle-aged adults over 30 years old in Ilsan area. The metabolic syndrome was diagnosed according to the data collected from each subject, including anthropometric measurements and blood analyses. The dietary patterns were derived from the average of two-day dietary intake data. Results: Factor analysis identified three major dietary patterns which were “Meats and alcohol”, “Mixed grains, vegetables and fruits”, and “Rice, Kimchi and fish & shellfish”. The daily intakes of energy, protein, and sodium increased across quartiles of “Meats and alcohol” pattern scores (p < 0.05), whereas the intakes of carbohydrates, potassium, calcium, and fiber increased across quartiles of “Mixed grains, vegetables and fruits” pattern scores (p < 0.001). The “Meats and alcohol” pattern scores were positively correlated with protein and sodium intakes but inversely correlated with carbohydrates, fiber and potassium intakes which were adjusted for age, sex and energy (p < 0.05). The highest quartile pattern score of “Meats and alcohol” pattern had elevated odds ratio of abdominal obesity and metabolic syndrome (p < 0.05). The risk of hypertriglyceridemia decreased in the highest quartile of “Mixed grains, vegetables and fruits” pattern (OR 0.35, 95% CI 0.12-1.00). Conclusions: Our results suggested that reducing the consumption of meat and alcohol along with increasing fruits, vegetables and mixed grains would be helpful for preventing the metabolic syndrome and chronic diseases.

Background: The dietary sodium-to-potassium ratio (Na:K) is known to have a stronger association with cardiovascular disease compared with a single intake of sodium or potassium. Accordingly, this study sought to examine the relationship between sodium-potassium intake balance and metabolic syndrome, which increases the occurrence of cardiovascular disease. Methods: Data from the Korea National Health and Nutrition Examination Survey 2013-2015 were used, and the subjects were 13,164 adults aged 19 years and over. This study examined sodium and potassium intake and Na:K based on Korean adults' age and sex, and analyzed food groups that contribute to adequate sodium and potassium intake based on an Na:K of 1. Correlations between Na:K, metabolic syndrome, and risk factors were examined through a multiple logistic regression analysis. Results: Korean adults' average daily intake of sodium was 3,976 mg, while that of potassium was 3,076 mg. Meanwhile, the Na:K was identified to be 2.33. The food group that contributed the most to potassium intake was fruits in subjects whose Na:K was below 1, and vegetables in those whose Na:K was over 1. Compared with the lowest quartile, the highest quartile in Na:K was up 19% in the probability that one would suffer from metabolic syndrome (P for trend=0.001). Also, more Na:K led to a significant increase in the risk of elevated blood pressure and elevated blood sugar (P for trend=0.015 and 0.012). Conclusions: A rise in Na:K is related to a risk of hypertension and high blood sugar, and such a rise raises the prevalence rate of metabolic syndrome. 연구배경: 식이 나트륨칼륨비는 나트륨이나 칼륨의 단독섭취보다 심혈관질환과의 연관성이 더 강한 것으로 알려져있다. 따라서 본 연구에서는 나트륨과 칼륨의 섭취 균형과심혈관질환의 발생을 증가시키는 대사증후군과의 관련성을살펴보고자 하였다. 방법: 본 연구는 2013-2015년 국민건강영양조사의 원시자료를 사용하였고, 최종 대상자는 만 19세 이상 성인 13,164명이었다. 한국인의 연령, 성별에 따른 나트륨, 칼륨의 섭취 및식이 나트륨칼륨비를 조사하고, 나트륨과 칼륨의 적정 섭취비율 1을 기준으로 나트륨과 칼륨의 섭취에 기여하는 식품군을 분석하였으며, 나트륨칼륨비와 대사증후군 및 위험요인과의 관련성은 다중 로지스틱 회귀분석을 사용하여 제시하였다. 결과: 한국인의 1일 평균 나트륨 섭취량은 3,976 mg이었고, 칼륨 섭취량은 3,076 mg이었으며, 나트륨칼륨비는 2.33인것으로 조사되었다. 칼륨 섭취에 대한 기여도가 가장 높은식품군은 나트륨칼륨비가 1 미만인 대상자들의 경우 과실류, 1 이상인 경우 채소류인 것으로 나타났다. 나트륨칼륨비가 가장 높은 사분위는 가장 낮은 사분위에 비해 대사증후군에 걸릴 확률이 19% 높았다(P for trend=0.001). 또한 나트륨칼륨비가 증가할수록 혈압 상승과 혈당 상승의 위험도가 유의하게 증가하는 경향을 보였다(P for trend=0.015와0.012). 결론: 나트륨칼륨비의 증가는 고혈압과 고혈당의 위험과관계가 있으며, 대사증후군의 유병률을 증가시키므로, 한국인의 식사에서 나트륨 섭취 감소와 함께 칼륨 섭취를 증가시켜 나트륨칼륨비를 감소시켜야 한다.

Background: The aim of this study was to assess the dietary fiber intake of middle-aged adults in Gyeonggi and to evaluate its relation with the metabolic syndrome. Methods: From April 2013 to October 2014, 279 (60 men, 210 women) middle-aged adults subject older than 30 years of age were recruited. Two-day dietary intake data were collected from each subject using the 24-hour recall method. Metabolic syndrome was diagnosed by anthropometric measurements, blood pressure, and blood analysis. Results: When the subjects were divided into tertile groups by dietary fiber intake per 1,000 kcal, the middle tertile group showed higher fiber intake of 118.8% above the reference intake of 12 g/1,000 kcal, and the highest tertile group showed a higher fiber intake of 165.0% above the reference intake. The group with greater dietary fiber intake showed more mineral and vitamin intake but less energy, fat, and cholesterol intake. The major food groups that contributed to the dietary fiber in the lowest and the middle tertiles were vegetables, grains, fruits, and legumes, but in the highest tertile, legumes contributed more than fruits. The risk of metabolic syndrome (odds ratio [OR] 0.38, 95% confidence interval [CI] 0.18-0.77), abdominal obesity (OR 0.45, 95% CI 0.23-0.85,) and hypertriglyceridemia (OR 0.42, 95% CI 0.21-0.83) were significantly reduced in the middle tertile compared to the lowest tertile. Conclusions: The results suggest that there is a correlation between dietary fiber intake and risk factors for metabolic syndrome. It is highly expected that consuming sufficient amount of fruits and vegetables as a major source of dietary fiber can prevent and manage metabolic syndrome and chronic disease. 연구배경: 본 연구는 경기 일부지역 중년 성인의 식이섬유 섭취수준을 파악하고 식이섬유 섭취량 수준에 따른 대사증후군 위험과의 관계를 알아보고자 하였다. 방법: 30세 이상 성인을 대상으로 2013년 4월부터 2014 년 10월까지 모집한 279명(남자 69명, 여자 210명)을 최종조사 대상으로 하였다. 식사섭취조사는 24시간 회상법을이용하여 2일간 조사하였고, 신체계측, 혈압측정과 혈액검사를 통해 대사증후군 여부를 진단하였다. 결과: 대상자를 1,000 kcal 당 식이섬유 섭취량을 기준으로 3분위로 분류하여 영양소 섭취를 비교하였는데 2분위군의 식이섬유 섭취는 기준치의 118.8%, 3분위군은 165.0% 로 식이섬유 섭취 기준치인 12 g/1,000 kcal을 상회하였다. 식이섬유 섭취량이 높을수록 대부분의 무기질과 비타민의섭취량은 높은 반면, 에너지, 지방과 콜레스테롤 섭취량은낮았다. 식이섬유 섭취에 기여하는 식품을 보면, 1분위와2분위군에서 식이섬유 기여식품군 순위는 채소류, 곡류, 과실류, 두류의 순이었으나, 3분위군에서는 두류가 과일류 보다 더 높은 순위를 보였다. 연령과 성별을 보정하였을 때식이섬유 섭취량 2분위군의 교차비가 1분위군에 비해 고중성지방혈증(OR 0.42, 95% CI 0.21-0.83), 복부비만(OR 0.45, 95% CI 0.23-0.85), 대사증후군(OR 0.38, 95% CI 0.18- 0.77) 위험이 유의하게 낮아지는 것으로 나타났다. 결론: 본 연구의 결과로부터 식이섬유 섭취수준과 대사증후군 위험요인 간에 관련성이 있는 것으로 나타났다. 따라서 식이섬유의 급원으로써 과일과 채소를 선택하여 충분한 양의 식이섬유를 섭취하는 것이 대사증후군을 예방및 관리할 수 있을 것으로 기대된다.

花粉粒 表面의 微細構造 : Ⅰ. 리기테에다소나무 Ⅰ. Pinus Rigittaeda

辛昌男,李深信 충남대학교 자연과학연구소 1982 忠南科學硏究誌 Vol.9 No.1

Palynalogical characteristics of Pinus rigittaeda were observed under the scanning electron microscope, hybrids of Pinus taeda and Pinus rigida. The density and size of chamber cap in the surface of Pinus rigittaeda were difference of Pinus rigida and Pinustaeda, but the size and pattern of pollen grain body and air bladder were similar. However, the pattern of chamber cap of pinus rigittaeda was similar to Pinus taeda, and the other characteristics were different.
