Purpose: Although excessive intake sugar may increase the overall energy intake, it leads to a reduction in the intake of foods containing other nutritionally adequate calories. Excessive sugar intake can also lead to an unhealthy diet, weight gain, and risk of metabolic disorders. The purpose of this study was to assess the recognition by college students, their frequency of eating sugar containing foods, and suggesting sugar reduction in the menus of institutional foodservices. Methods: A questionnaire was used to survey 145 college students to evaluate their recognition and eating frequency of consuming sugar containing foods. Subsequently, sugar reduction menus for institutional foodservice were suggested. Results: Most of the subjects (80.0%) were aware of the meaning of sugar reduction. The necessity of reducing sugar in their meals was recognized by 57.8%. These participants tended to check nutrition labeling more. Eating frequencies of sugar containing foods were not significantly different by the subjects' BMI, but they were significantly different by gender, when evaluating cooked foods. We suggested 20% sugar reduction recipes of Korean style barbequed pork, and sweet and sour chicken for institutional foodservices. Conclusion: The awareness of college students and the knowledge regarding sugar reduction were low. Sensory acceptabilities of Korean style barbequed pork and sweet and sour chicken were not significantly different, until the benefit of 20% sugar reduction was mentioned. Thus, continuous education for reduction of sugar intake are required, and also efforts are needed to develop menus containing less sugar.

치주질환은 만성염증성 질환으로 치조골소실을 일으켜 성인치아상실을 유발하는 요인 중 하나이다. 그람 음성세균인Aggregatibacter actinomycetemcomitans와 Porphyromonas gingivalis는 치주질환환자의 병소에서 쉽게 동정된다. 지질 다당체(Lipopolysaccharide; LPS)는 그람 음성세균의 핵심 독력인자로 알려져 있다. 이러한 세균과 LPS는 파골세포에 의한 골소실을 조절하는 요인 중 하나이다. 그러므로 본 연구에서는 동물모델을 활용하여 A. actinomycetemcomitans와 P. gingivalis의 의한 골소실 여부를 확인하고, 기전규명을 위하여 A. actinomycetemcomitans, P. gingivalis, A. actinomycetemcomitans와 P. gingivalis에서 분리한 LPS에 의한 파골세포분화 영향을 연구하였다. 열사멸한 A. actinomycetemcomitans (HKAa)와 열사멸한 P. gingivalis (HKPg)가 복강으로 투여된 쥐의 대퇴골은 대조군에 비해 감소된 골량을 보여주었다. 이러한 골소실의 증가가 파골세포분화 때문인지 확인하기 위해 파골세포분화를 연구한 결과, bone marrow-derived macrophage (BMM)의 RANKL-매개 파골세포분화를 감소시켰으나, committed osteoclast precursor의 파골세포분화를 유도함을 확인하였다. 세균에 의한 파골세포분화 결과와 동일하게 A. actinomycetemcomitans와 P. gingivalis에서 분리한 LPS 역시 RANKL-매개 파골세 포분화는 감소시키고, committed osteoclast precursor의 파골세포분화를 유도하였다. 결과적으로 치주원인균인 A. actinomycetemcomitans와 P. gingivalis는 committed osteoclast precursor의 파골세포분화를 증가시키는데, 이 세균들의 LPS가 핵심 역할을 수행하는 것으로 판단되며 이를 통해 골 흡수를 유발함을 알 수 있었다. Aggregatibacter actinomycetemcomitans and Porphyromonas gingivalis are gram-negative bacteria frequently found in lesions from patients with periodontitis manifesting alveolar bone loss. Lipopolysaccharides are a major virulence factor of gram-negative bacteria. Bone resorption is known to be regulated by bacteria and their virulence factors. In the present study, we investigated the effects of A. actinomycetemcomitans and P. gingivalis on bone resorption. Heat-killed A. actinomycetemcomitans (HKAa) and heatkilled P. gingivalis (HKPg) induced bone loss in the femurs of mice after intraperitoneal administration. HKAa and HKPg augmented the differentiation of committed osteoclast precursors into osteoclasts, while they inhibited the differentiation of bone marrow-derived macrophages into osteoclasts. Concordant with the effects of the heat-killed whole cells, LPS purified from A. actinomycetemcomitans and P. gingivalis also augmented osteoclast differentiation from committed osteoclast precursors but attenuated it from bone marrow-derived macrophages. Taken together, these results suggest that the whole cells and lipopolysaccharides of A. actinomycetemcomitans and P. gingivalis induce the differentiation of committed osteoclast precursors into osteoclasts, potentially contributing to bone resorption in vivo.

This study evaluated the effect of nutritional improvement of 0~5 year children of financially poor families after nutrition supplement of children and nutrition education in parents/guardians. The subject selected among applicants for lowincome family financing of the government included 198 children (0~12 months:92, 1~5 years:106), and the average ages were 5.3 months and 2.4 years respectively. Food that includes each nutrient factor was provided to the subject for six months. Nutrition education was performed in two ways, through class and private education, once a month for both. Nutritional improvement was evaluated by body measurement and anemia prevalence rate. As to the survey on breastfeeding, complete breast-feeding accounted for 58.7%, weaning food 27.3%, and combined feeding 14.1% respectively, which shows that breast-feeding accounted for the largest percentage. The education program improved knowledge and attitude of the parents/guardians, which brings in positive effects on growth of children as well. The nutrition knowledge score was improved after nutrition education in 0~12 month children (8.5 ± 1.75 to 8.9 ± 1.69) and 1~5 year children (7.3 ± 1.39 to 7.8 ± 1.30). The nutrition attitude score was significantly improved in 0~12month children (52.0 ± 6.99 to 53.5 ± 5.21, p < 0.001) and 1~5year children (45.1 ± 7.30 to 49.0 ± 5.96, p < 0.001). In evaluation on nutritional improvement based on body measurements, it turned out that the wasting was reduced as for children in consideration of the height and weight according to the subject`s age. The concentration of hemoglobin after the nutrient treatment for six months was significantly improved, and the anemia prevalence rate as well was reduced from 40.6% to 13.5%, which indicates the significant improvement. Based on the findings above, it turned out that providing quality food to children and nutrition education to the parents/guardians poorly fed in low-income families improved knowledge and attitude of the guardians and prevents anemia and improves growth, which brings in positive effects on growth of children. In the results regarding attitude and knowledge on nutrient/dietary life; however, the improvement level was relatively low when the extent before the education was too small, which indicates the need to revise and complement the contents and methods. In addition, as shown in the result of body measurement, long-term and consistent investigation is necessary since it is difficult to judge the effect on growth only based on short-term nutrient supplement.

『하얀 악마』의 비토리아 연구: 사회구조의 희생자로서의 여주인공
박옥진 ( Park Ok-jin ) 대한영어영문학회 2016 영어영문학연구 Vol.42 No.1
This study is to scrutinize the social structure which surrounds Vittoria, the female protagonist in The White Devil, and the process through which she is defined as a victim. The White Devil deals with the struggle of a woman who refuses to be unjustly defined as a "whore" or "devil" by the patriarchal society. Vittoria tries to keep her selfhood by revealing the fact that her social identity as a whore is not based on any truth but socially has been "constructed" by patriarchal authorities. Dramatic methods, such as the trial scene or arguments, clearly show us the way patriarchal authorities fortify the oppression of women by "constructing" female sexuality as socially destructive. On the other hand, because Vittoria defends herself with the same rhetorical strategy as her accusers, which hides truth under the cover of authorities, we cannot simply evaluate her as an admirable heroine who overcomes the oppression of a patriarchal society. Nonetheless, Vittoria's effort to keep her selfhood, or in other words, her powerful self-assertion, is a subversive energy which can pose a fundamental question about the basic structure of patriarchal society, revealing the hidden mechanism with which patriarchal authorities dominate womankind.

박옥진(Park Ok-Jin) 신영어영문학회 2003 신영어영문학 Vol.25 No.-
This study is about John Webster's attitude towards the chaotic world of the early seventeenth century in England by examining Flamineo, a villain character in The White Devil. The world that John Webster's The White Devil reveals is a dark one governed by Machiavellian power structure in which its appearance and reality are different and evil prevails. Flamineo, as a villain character, is a frustrated intellectual that is alienated from the power and constantly strives to attain the power to no avail. Flamineo epitomizes the whole class of Englishmen whose ambitions for public service produce only disenchantment. He typifies the plight of the intellectual in the world of state, at once its agent, and its victim. Through Flamineo, Webster severly criticizes this situation which intellectuals encounter in the society in which they cannot be provided with a place to use their talents and fulfil their sense of self-esteem and honour. In conclusion, Webster satirizes through the dramatic type of scholarly malcontent, Flamineo. Jacobean England where moral values and political aims were corrupted.
