This study was conducted to investigate the dietary and other factors affecting bone mineral density (BMD) in older Korean women. A total of 340 women aged 65 to 74 were recruited from the Kugoksoondam area (Kurye, Goksung, Soonchang and Damyang counties), known as the longevity-belt region in Jeonla province, Korea. They were categorized into two groups according to bone status by T-score : a nonosteoporotic group and an osteoporotic group. Demographic characteristics were collected, as well as information on physical measurements, blood tests for biochemical indicators, health status health-related life style, dietary behavior, favorite food groups, nutrient intake and mini nutrition assessment (MNA). The results are as follows: The mean age of 185 nonosteoporotic women was 69.6 years and that of 155 osteoporotic women was 70.9 years (p<0.001). The mean T-score of the nonosteoporotic group was $-1.5mg/cm^3$ and that of theosteoporotic group was $-3.2mg/cm^3$ (p<0.001). Height and body weight in the nonosteoporotic group were significantly higher than in the osteoporotic group (p<0.001, respectively). There was no significant difference in BMI, although the BMI in the nonosteoporotic group was slightly higher. Waist and hip circumferences in the nonosteoporotic group were significantly higher than in the osteoporotic group (p<0.01, respectively), and the mid upper arm and calf circumferences were also significantly higher than in the osteoporotic group (p<0.001, p<0.01, respectively). The 5 m walking ability was significantly superior compared to the osteoporotic group. Serum levels did not show any significant differences between the groups and were within normal range. The serum total protein, albumin and Insulin-like growth factor (IGFs) levels of the nonosteoporotic group were significantly higher than those of the osteoporotic group (p<0.05, p<0.05, p<0.001, respectively). IGF was 104.7 ng/mL for the nonosteoporotic group and 88.1 ng/mL for the osteoporotic group. Physical activity and appetite in the nonosteoporotic group were significantly higher (p<0.01, p<0.05, respectively). The favorite food groups of the nonosteoporotic group comprised more meats and fish than those of the osteoporotic group (p<0.05, respectively). Nutrient intake was not significantly different, with the exception of niacin intake (p<0.05), but the nutrient intake of the nonosteoporotic group was slightly higher than that of the osteoporotic group. The niacin intake of the nonosteoporotic group and the osteoporotic group were 11.4 mgNE and 10.0 mgNE, corresponding to 103.6% and 90.9% of the Korean EAR, respectively. The MNA score of the nonosteoporotic group was significantly more favorable than for the osteoporotic group. In conclusion, it is necessary to maintain adequate body weight and muscle mass. Habitual physical activity may have a beneficial effect on BMD for older women. Dietary factors, such as meat and fish, higher intake of niacin rich foods and nutrient status for older women also appear to have favorable effects on bone mineral density.

The objective of this study was to investigate the health status and nutritional intake of the old population living in Soonchang, Jeollabuk-do, Korea. 69 subjects aged 65 years and older were recruited in July 2016. The WHR, was significantly higher in elderly male group than elderly female group (p<0.05), but both groups had abdominal obesity (0.85 and over). T-score mean of elderly male and female groups were below $-2.5mg/cm^3$ that they were osteoporotic. In the elderly male group, the higher concentrations of creatinine, homocysteine and uric acid were found to be significantly unfavorable factors (p<0.001, respectively). The blood vitamin $D_3$ levels of elderly male group was significantly higher than that of elderly female group (p<0.05). The physical activity and self-rated health were significantly higher in elderly male group than in elderly female group (p<0.05, p<0.01, respectively). The nutrient intakes of male group were found to be significantly favorable factors than in female group. The score of mini nutrition assessment was significantly lower in elderly female group than in the elderly male group. These results could be useful to plan effective strategies to increase the health-life expectancy and the prevention of disease of Korean elderly people living in rural areas.

수세미오이(Sponge-gourd: Luffa cylindrica L.) 추출물의 항산화, 항돌연변이 및 암세포 증식 억제 효과

오세인,이미숙,Oh, Se-In,Lee, Mee-Sook 한국식품영양학회 2012 韓國食品營養學會誌 Vol.25 No.4

Considering the dearth of information regarding the medicinal properties of Luffa cylindrica, we assessed the antioxidative, antimutagenic and hyperplasia inhibitory activity of cancer cells from Luffa cylindrica extracts by employing biological and biochemical assays. Ethanol extracts of Luffa cylindrica inhibited MDA-BSA (malondialdehyde-bovine serum albumin) conjugation reaction ($66.38{\pm}2.65$), DPPH (1,1-diphenyl-2-picryl-hydrazyl) radical production ($60.13{\pm}0.42$) and lipid peroxidation ($56.04{\pm}3.24$). In this study, Luffa cylindrica is believed to exert possible antioxidative effects. The direct and indirect antimutagenic effects of the ethanol extracts of Luffa cylindrica were examined by the Ames test using Salmonella typimurium TA98 and TA100. The inhibitory effects on indirect and direct mutagenicity shows an weak tendency, particularly in direct mutagenicity mediated by 2-nitrofluorene in Salmonella typimurium TA98 ($5.82{\pm}5.74$) and in indirect mutagenicity mediated by 2-anthramine in Salmonella typimurium TA100 ($5.76{\pm}2.15$). The ethanol extracts of Luffa cylindrica on cancer cell hyperplasia inhibitory activity via MTT (3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide) assay exerted cytotoxic effects on Hela cells ($55.83{\pm}3.83$) and MCF-7 cells ($33.03{\pm}2.09$), which were used in this study. Based on these results, it believed that the ethanol extracts of Luffa cylindrica have antioxidative capacities as well as hyperplasia inhibitory activity of cancer cells. Furthemore, Luffa cylindrica is a candidate for the prevention and dietetic treatment of chronic diseases and for the development of functional food.

전라도에 거주하는 여자노인의 당화혈색소 수준에 따른 건강위험인자의 비교분석 - 생화학적 요인, 식습관 및 영양상태 -

The purpose of this study was to investigate the relations between HbA1c level and health risk factor. For analysis, 330 elderly women aged 65 years and over were recruited in Jeonla province, Korea. The subjects were classified into two groups according to their HbA1c level; the diabetic group (HbA1c level${\geq}6.5%$, n=68, 20.6%) and control group (HbA1c level<6.5%, n=262, 79.4%). Demographic characteristics were collected, as well as information on physical measurements, blood tests for biochemical indicators, a health status and health-related life style, dietary behavior, favorite food groups, consumption frequency of food groups and nutrient intake. Educational level of the diabetic group was significantly lower than that of the control group. The height of the diabetic group was shorter, and percentage fat of the diabetic group was higher than those of the control group. In the diabetic group, the higher concentrations of creatinine and activity of alkaline phosphatase were found to be significantly unfavorable factors. Therefore, the diabetic group was assumed to be at risk of decreased liver and renal function. The self-rated health level of the diabetic group has a declining tendency, while the medicine intake was significantly higher than that of the control group, but there are no significant differences in visiting frequency of hospital and community health center. The distribution of physical activity showed a significant difference between the groups. Although there are no significant differences in nutrient intake, the diabetic group had relatively inferior nutrient intake of diet, especially vitamin C, as contrasted with the control group. In conclusion, the weight control and increasing physical activity may be effective in the prevention of the diabetes and continuous education and intervention by specialized nutritionists will be needed for diabetic patients. These results could be useful to plan effective strategies to increase the health-life expectancy and the prevention of the diabetes of Korean elderly people living in rural areas.

The purpose of this study was to compare the degree nutrient intake, health status and other characteristics of females aged 65 years and over in a longevity area according to family arrangement. For analysis, 585 female elderly were recruited from the Kugoksoondam area (Kurye, Goksung, Soonchang and Damyang counties), known as the longevity-belt region in Jeonla province, Korea. The subjects were categorized into three groups according to family arrangement (living alone, living with spouse only and living with family). Demographic characteristics were collected, as well as information on physical measurements, blood tests for biochemical indicators, health status and health-related life style, dietary behavior, favorite food groups, consumption frequency of food groups, nutrient intake and mini nutrition assessment. In the group living with their spouse only, the highest education, physical activity, diverse food intake, frequency of eating meats and fish, energy and nutrients intake, and score on the mininutrient status assessment (MNA) were found to be significantly favorable factors. Taken together, these results demonstrated that the group living with their spouse only had relatively superior nutrient intake and the quality of diet. In contrast, the group living alone showed the lowest self-rated economic status, diversity of food intake, and physical activity, with the highest frequency of drinking, smoking and regular exercise for almost everyday compared with the other groups. On the other hand, those living with family demonstrated the lowest intake of supplements or functional foods, and levels of hemoglobin hematocrit MCH, but the highest HBA1c and blood sugar. Therefore, the group living with family was assumed to be at risk of anemia and diabetes. These results could be useful to plan effective strategies to increase the health-life expectancy of Korean elderly people living in rural areas, according to family arrangement.

1920~1930년대 신문과 잡지에 나타난 공간 표상의 변화 과정 연구

오세인(Oh, Se-in) 한국시학회 2016 한국시학연구 Vol.- No.46

이 논문의 목적은 1920~1930년대 신문과 잡지 기사에 나타난 ‘거리(街)’의 표상 변화를 살펴봄으로써 당대의 개별 주체들이 전근대와 근대의 길항과 교착을 어떻게 인식했는지 규명하는 것이다. 근대 초기 ‘거리’에 물리적으로 구현된 근대성과 도시성은 오랫동안 전근대적 삶의 양식에 익숙해 있던 사람들에게는 너무나 새롭고 낯선 것이었다. 사람들은 신문과 잡지, 소문과 이야기를 통해 간접적으로 접한 후에 ‘거리’로 나가 물리적으로 구현된 근대성과 도시성을 직접 경험했다. 따라서 신문과 잡지 기사에서 근대 도시를 표상하는 공간인 ‘거리’를 묘사하는 방식을 살펴본다면 근대성과 도시성이 경험되고 이해되는 양상과 그러한 경험과 이해가 불러온 개별 주체의 내적, 외적 변화의 실상을 밝힐 수 있다. 1920년대의 신문과 잡지는 실업과 가난으로 집도 없이 ‘거리’를 떠도는 조선인들에 대한 기사를 쏟아냄으로써 일제에 의해 진행된 자본주의 근대 도시화가 차별적인 것이었음을 보여주었다. 1930년대 중반 이후에는 ‘거리’를 사람들에게 ‘즐거움’을 주는 ‘그리움’과 ‘애착’의 대상으로 그렸다. 이는 ‘거리’가 자본주의 근대 도시를 표상하는 ‘공간’이자 근대 주체의 일상생활이 이루어지는 ‘장소’로서의 성격을 갖게 되었음을 잘 보여준다. This research aims to investigate how modern subjects perceived the opposition and mixture of modernity as a ‘space’ and premodernity as a ‘place’ from 1920s to 1930s. To unlock the way modernity and urbanity were experienced and understood and the truth of internal and external changes of individual subjects brought by the experience and understanding of them, it examines articles of newspapers and magazines of the time and traces the process in which a ‘street’ appeared as a representation of modern space and changed. In 1920s, by producing many articles about jobless and poor Koreans wandering the ‘street’, newspapers and magazines revealed that modernization and urbanization by the Japanese colonial government were highly discriminative. After mid 1930s, they depicted a ‘street’ as the object of ‘longing’ and ‘attachment.’ This proves that a ‘street’ is a ‘space’ which represents modern capitalist city and it possesses the characteristics of a ‘place’ where modern subjects lead their daily lives. In this way, a ‘street’ settled down as a ‘space’ representation of capitalist modern city and as a ‘place’ of daily lives in the city.

1930년대 문학과 ‘감각’의 문제 : 김기림과 임화의 시론을 중심으로

오세인(Oh Se-in) 한국시학회 2011 한국시학연구 Vol.- No.30

This paper aims to examine the difference in concept 'sensation' described in Kim, Gi-rim and Im, Hwa's poetic theories. In Kim's theory, sensation is the method of realizing objective world in subjectivity. Im, Hwa's sensation drives practical action with perception and judgment of objective world. Kim's sensation is close to romanticism in that it emphasizes the subjectivity, however, it surpasses romanticism because the subjectivity keeps moving to catch the changing reality. Objective world accepted through sensation is perceived and reasoned within subjectivity and expressed in poetic language. Therefore, the role of sensation, inducing objective world into the world of subjectivity becomes very crucial to Kim in writing a poem. In Im, Hwa's theory, sensation of intelligence participates in the process of reasoning and emotion is a definitive one that comes after the confirmation of fact with reasoning and is connected to a certain action. Im, Hwa put an emphasis on sensation of intelligence because he thought that an object could secure facticity only when it is perceived and reasoned with sensation of intelligence. In that judgment drives practical action, his sensation is different from Kim's sensation or intelligence which participates only in subjective acceptance and perception of objective world.

근대 도시의 청각적 재구성 : 1920년대 카프 시를 중심으로

오세인(Oh Se-In) 한국시학회 2010 한국시학연구 Vol.- No.28

This paper aims to examine the poetry of Korea Proletarian Artist Federation(KAPF) in the mid and late 1920s and clarify that their recognitions of urban contradictions and poetic embodiment of them are based on senses, especially on acoustic senses. The acoustic senses were the medium for KAPF poets of 1920s to overcome the ideality and abstractness of socialist ideology and struggle into the concreteness of life and the methodology of combining aesthetic and political practice. In 'Dohoe Jeongjo'(Urban Atmosphere), Park, P'aryang defines the sounds from the street and the movement of people on the streets as 'great flow of muddy stream'. The urban street is modern in that all classes are mixed and forms one flow but also contradictory and dual in that each class should go back to its life in the end. By contrasting the sound of machine in the factory and the moaning of beggars against the peal of church bells, Kim, Haegang tell us that truth are different according to the reality of each class. He also portrays the dissonance of contrary sounds and by calling it as 'symphony', he satires the structural contradictions of capitalist society. He reveals that the possibility of fulfilling the desires of proletarian people is blocked as the headlight of the car could not pass through the wall. Park, P'aryang and Kim, Haegang do not list political slogans nor repeats abstract statements, instead, by arranging contrary sounds in the same space-time and making them collide, they intentionally reveal the class contradiction and urban problems. Therefore, city and everyday life of people in it are acoustically restructured in their poems. The importance of examining poems of KAPF poets in 1920s is in that by comparing them to those of 1930s, political or practical and aesthetic features of both periods could be revealed more distinctively.

한일 근대 문학에 나타난 `감각` 개념의 비교 연구

오세인 ( Oh Se-in ) 한양대학교 동아시아문화연구소(구 한양대학교 한국학연구소) 2017 동아시아 문화연구 Vol.70 No.-

이 논문은 한국과 일본의 근대 문학 형성기에 `감각`이 어떠한 의미를 갖는지 밝히기 위해 1920년대 일본 `신감각파`의 `신감각`과 1930년대 김기림의 `감각` 개념을 비교하여 살펴보았다. `신감각파`와 김기림은 자본주의 근대 도시라는 유사한 삶의 조건 속에 놓여 있었음에도 불구하고 현실에 대한 인식의 차이로 인해 `감각`의 개념이나 역할을 다르게 제시했다. 요코미쓰 리이치와 가와바타 야스나리 등으로 대표되는 일본의 `신감각파`는 반자연주의, 반리얼리즘, 반사소설의 기치 아래 `새로운 시대`에 필요한 `새로운 문예`를 추구했다. 이들은 `새로운 시대`를 긍정적인 시공간으로 보았기 때문에 `새로운 감각`을 통한 `새로운 표현`의 창조가 곧바로 `새로운 문예`의 창조로 이어진다고 보았다. 그 결과 이들이 추구한 `신감각`은 표현과 `문체의 새로움`에만 한정되었다. 일본의 `신감각파`와 달리 김기림은 피식민지 근대 주체로서 자본주의 근대 도시의 이중성을 인식하고 있었다. 또한 `기교`와 `감각`에 대한 프로문학의 비판과 이들이 요구하는 `내용`에 대한 압력을 외면할 수도 없었다. 그래서 `감각`의 중요성을 강조하면서도 `감각`을 통해 현실을 인식하고 표현해야 한다고 주장했다. 김기림은 `감각`을 자본주의 근대 도시의 속성을 이해하고 이를 문학적으로 형상화하는 매개로 규정하고자 했던 것이다. 다시 말해 일본의 `신감각파`가 자본주의 근대 도시의 속성을 `문체의 새로움`을 통해 감각적으로 표현함으로써 근대 문학을 구축하려 했다면, 김기림은 `감각`을 매개로 객관세계와 주관세계의 어긋남을 표현함으로써 근대성과 도시성에 내재된 이중적 속성을 드러내야 하는 한국 근대 문학의 과제를 수행하고자 했다. This paper compared `New Sense` of Japanese Neo-Sensualism Group in 1920s and `Sense` of Kim, Gi-rim in 1930s to investigate the meaning of `Sense` in the forming period of modern Korean and Japanese literature. Their concepts have become different due to their disparity in the perception of reality, even though they were living in the similar conditions, capitalist modern city. Japanese Neo-Sensualism Group sought for `new literature` required for `new era` under the banner of anti-naturalism, anti-realism and anti-autobiographical novel. They considered `new era` as a positive space and time, and claimed that the creation of `new expression` through `new sense` would lead to `new literature.` As a result, their `new sense` was limited to being new in `style` and `expressions.` Unlike Japanese Neo-Sensualism Group, as a modern subject of colonized Korean, Kim, Gi-rim was aware of the duality in the capitalist modern city. He also could not turn away from the criticism on him and the request of `contents` by proletarian group. Therefore, emphasizing the importance of `sense`, he also insisted that subjects of modern Korean literature should perceive and express reality through `sense.` In other words, Kim, Gi-rim tried to define `sense` as a medium of understanding capitalist modern city and expressing it in literary works. In other words, Japanese Neo-Sensualism Group intended to construct modern literature by sensually expressing the characteristics of capitalist modern city with `new style`, however, Kim tried to perform the task of modern Korean literature, revealing the dual nature in modernity and urbanity by expressing the deviation of objective and subjective world.

전라도 구곡순담 장수벨트지역에 거주하는 중노년층의 체격지수와 영양소 섭취상태

As the older adult period (≥65y) is increasing, it is needed to investigate the trend of aging-dependent anthropomeric index and nutrient intake, and establish the more specific dietary guide for the different stages of aging period. To find the difference in nutrient intake among the Koreans aged 50-64, 65-74 and 75 years and older, and also any characteristics of dwellers in longevity area, we recruited 1,083 subjects (385 male and 698 female) aged 50-95 years (mean age, 71.3yrs) living in Kugoksoondam area (Kurye, Goksung, Soonchang and Damyang counties), known as a longevity-belt region in Jeonlaprovince, Korea. We measured some anthropometric index and collected 2 day-dietary record. Nutrient intakes were analyzed by using DW24 program. The mean height and weight of subjects aged 75 years and older were lower than Korean national reference. BMI and obesity (BMI≥25kg/m2) prevalence were significantly decreasing with aging. Underweight (BMI<18.5kg/m2) prevalence was also increasing with aging, especially in males, and it was slightly higher than national average, but similar to that in some other rural area. Obesity prevalence of male subjects was lower compared to national prevalence, but abdominal obesity prevalence (waist≥80cm) was very high in females (about 89%). In both genders, the average proportional contribution of carbohydrate, protein and fat to energy intake was not different between 65-74 years and 75 years and older. On overall, nutrient intake and quality of diet of females were inferior to those of males so that many of females aged 75 years and older assumed to be at risk of malnourished status. Fiber, folate and vitamin E intakes were substantially higher compared to those in 2007 KNHNES and other some studies in rural area. While almost nutrient %EAR was significantly decreased with aging in females, there was no significant difference in %EAR for protein, vitamin A, B1, B6, B12, niacin, Ca and Zn between 65-74 years and 75 years and older in males. Vitamin B2 for male aged 50-64 years, vitamin B2 and Ca for male aged 65 years and over and female aged 50-74 years, and vitamin B2, vitamin C, Ca and folate intake for female aged 75 years and older were assessed to be at risk to undernutrition based on the prevalence of intake below EAR. MAR of 13 nutrients and the number of nutrients consuming below EAR were significantly decreasing with aging in both genders, however, the number of nutrients of INQ < 1 and the average mini-nutritional assessment score were not significantly different between 65-74 years and 75 years and older. Taken together, decreasing tendency of nutrients intake and the quality of diet with aging was more evident in females than in males, and it is unique that our subjects consumed substantially higher fiber, folate and vitamin E compared to not only urban but also some other rural areas.
