The purpose of study was to examine the factors influencing fast food consumption in Korean adolescents. The analysis was conducted using cross sectional study data from the 16^th Korea Youth Risk Behavior Web-based Survey in 2020. A total 54,948 middle and high school students participated in this study. The subjects in the analysis were 28,353 males and 26,595 females, 28,961 middle school and 25,987 high school students. In total, 56.6% Korean adolescents consumed fast food once or twice weekly and 25.4% consumed fast food more than three times weekly. Logistic regression analysis revealed that fast food consumption was significantly associated with dietary behavior such as lower breakfast intake (OR: 0.930, 95%CI: 0.891~0.970, p<0.001), higher soda drinks consumption (OR: 2.563, 95%CI: 2.452~2.678, p<0.001), and higher sweet drinks consumption (OR: 1.898, 95%CI: 1.818~1.982, p<0.001). For psychological and health behavior factors, fast food consumption was also significantly associated with higher perceived stress (OR: 1.239, 95%CI: 1.163-1.321, p<0.001), higher smoking (OR: 1.300, 95%CI: 1.164~1.453, p<0.001), higher drinking (OR: 1.193, 95%CI: 1.112~1.280, p<0.001), higher depression experience, higher loneliness experience, and lower subjective health, In conclusion, fast food consumption in Korean adolescents was associated with undesirable dietary habits and psychological and health behavior, suggesting that appropriate education programs are necessary to reduce such behavior.

핵산증폭시험을 이용한 혈장분획물질에서 HCV RNA 검출

홍승희,Hong, Seung-Hee 한국미생물학회 2008 미생물학회지 Vol.44 No.4

HCV는 HIV등과 함께 수혈이나 혈장된 획물질을 통하여 감염되는 주요 바이러스이다. 주로 혈액이나 혈장에서 HCV에 대한 항체를 검출함으로서 HCV의 감염을 방지하고 있다. 그러나 바이러스에 감염되었으나 항체가 생성되기 이전이나 항체의 양이 적은 경우에는 HCV의 검출이 어렵다. 따라서 핵산중폭시험(nucleic acid amplification tests, NAT)을 이용한 HCV 유전자를 검출하려는 시도들이 진행되고 있다. 이 연구의 목적은 혈장분획물질에서 HCV RNA를 검출할 수 있는 핵산증폭시험 방법을 개발하는 것이다. 5종류의 PCR primer를선별하여 실험에 이용하였다. 혈장분획물질의 HCV RNA 추출에는 컬럼 방법을 이용하는 것이 유용한 것으로나타났다. 핵산중폭시험의 결합 온도는 $48^{\circ}C$가 가장 적절한 것으로 나타났다. 또한 2차 PCR의 경우, 1차 PCR 산물 $1{\mu}l$와 30 pmol의 primer즐 사용하였을 때 높은 민감도와 특이성을 보이는 것을 알 수 있었다. 혈장 분획물질에 HCV를 주입하여 혈장중폭시험을 수행한 결과, 100 IU/ml까지 검출 할 수 있었다. 한편 근육주사용항체(IMIG)의 경우 핵산중폭시험을 통한 검출한계는 100IU/ml로 COBAS amplicor HCV2.0의 500 IU/ml 이상의 검출한계보다 민감도가 더 높은 것으로 나타났다. 이러한 결과들로 보아 본 실험에 이용된 핵산증폭시험이 혈장분획물질에서 HCV RNA를 검출하는데 유용한 방법으로 사용될 수 있을 것으로 생각된다. HCV is transmitted via various plasma derived products. Current methods to detect hepatitis C virus (HCV) are based on its antibody detection in the donated blood and plasma. Viral contamination can potentially escape such detection during the window period of infection, when no antibody is present or the level of antibody is too low to detect. It is trying to application of nucleic acid amplification tests (NAT) for the direct detection of HCV. The objective of this study was to develop a reliable NAT for the HCV RNA detection from plasma-derived products. The most useful primers was selected for NAT among 5 sets of primers. We have also found that QIAamp viral RNA isolation kit was the most efficient for HCV RNA isolation. The highest sensitivity and specificity was appeared in $48^{\circ}C$ annealing temperature and 30 pmol of primers. With a spiking of HCV to albumin, immunoglobulins and coagulation factors, NAT can detect up to 100 IU/ml. Meanwhile, COBAS amplicor HCV 2.0 afforded a lower sensitivity in high concentrated intramuscular immunoglobulins to below 500 IU/ml. Our results suggested that NAT appears to be a highly sensitive and specific method for HCV RNA detection in plasma-derived products.

홍승희,이보라,박영심,Hong, Seung-Hee,Lee, Bo-Ra,Park, Young-Sim 한국식품영양학회 2015 韓國食品營養學會誌 Vol.28 No.1

In this study, we investigated the dietary habits, snacks, and self-purchasing snacks (SPS) intake behaviors of 519 elementary school students (boys=239, girls=280). Obesity was significantly higher (p<0.05) in boys (24.8%) than in girls (14.7%) and the proportion of underweight subjects was higher compared to normal or other weight groups for both the boys and the girls. There were 7.5% of the subjects in the group that always skipped breakfast, and the main reason of skipping breakfast was insufficient time (51.9%). The snack intake frequency was once or twice per week for 23.1% of the subjects and three or four times per week for 25.1%. The SPS intake frequency was the subjects zero for 35.6% of the highest level of the responders, while 6.8% of the respondents took more than once SPS per day. 59.6% of the respondents consumed SPS due to hunger while 15.0% consumed SPS out of boredom. The SPS was purchased from supermarkets in 34.5% of the cases, from convenience stores in 24.1% and from snack corners in 20.0% of cases or from a store near school in 14.5% of the cases. Analysis of SPS behaviors according to obesity index showed that parent's opinion of 'permission to buy SPS as needed' had a significant effect in 64.5% over weight subjects compared to only 53.7% in underweight groups. The subjects who used more than 3/4 of their pocket money to buy SPS was higher in the overweight groups (16.4%) than in the underweight groups (7.0%) and normal weight groups (9.8%). The favorite snacks and SPS were milk and yogurt for 45.7% of the subjects, fruits for 42.7%, ice cream for 26.4%, fruit juices for 23.8%, sweet stuff for 16.4%, frozen dessert for 8.9%, and chocolate or candy for 8.1% in descending order. The intake frequency of milk, yogurt, and fruit juices was higher in the underweight groups, but the intake frequency of sweet stuff, frozen dessert, and chocolate or candy was higher in over weight groups. The intake of frozen dessert was more than four times higher in the overweight groups than in the underweight groups. In conclusion, dietary habits, snacks, and SPS intake behaviors were similar between the boys and the girls and obesity groups, but most students appeared to have a high preference for intake snacks and SPS. Therefore, education for appropriate snacks intake habits will be beneficial for improving their dietary habits and health.

대표권남용의 약속어음발행에 있어서 배임죄의 보호정도와 미수·기수성립범위 - 대법원 2017. 7. 20. 선고 2014도1104 전원합의체 판결 -

홍승희 ( Seung-hee Hong ) 법조협회 2018 최신판례분석 Vol.67 No.2

대표권남용의 무효인 약속어음발행에 있어서 종전 판례들은 배임죄를 위험범으로 이해하여 ‘어음의 유통가능성’을 기준으로 배임죄의 기수범 성립여부를 판단하였다. 이에 반하여 대상판결은 이러한 종전 판례의 입장을 변경하여 이제는 ‘실제로 어음이 제3자에게 유통되었는지’ 여부를 기준으로 배임죄 기수성립을 판단하면서 재산상 손해에 해당하는 구체적·현실적 위험이 초래되었다고 볼 수 없는 경우에는 배임미수죄가 성립한다고 판시하였다. 대상판결은 배임죄의 구성요건인 ‘재산상 손해발생’을 종전 판례들과 마찬가지로 ‘현실적인 손해 또는 재산상 실해발생의 위험’으로 파악하여 배임죄를 위험범으로 이해하고 있다. 그러면서도 미수성립 및 기수성립시기에서는 종전판례와 큰 차이를 보인다. 이러한 차이는 대상판결의 경우 배임죄를 위험범 중에서도 특히 ‘구체적 위험범’으로 파악한 것으로 평가될 수 있는데, 이러한 위험은 막연한 일반적인 위험이 아닌 현실적인 손해발생과 동등할 정도의 재산위태화를 의미하는 ‘손해동등위험’으로 간주될 수 있기 때문이다. 오늘날 복잡해지고 역동적으로 변화하는 ‘재산’ 개념을 고려할 때 이러한 판례의 태도는 바람직한 것으로 보이며, 특히 그동안 형해화되었던 배임미수규정을 복원하였다는 점에서 의의가 있다고 하겠다. Die bisherigen Rechtsprechung schatzen einen schutztenden Grad von Untreue als Gefahrdungsdelikte. Dagegen schatzt die uberwiegende Meinung als Verletzungsdelikt. Das 2014do1104 Urteil schatzt auch Untreue noch als Gefahrdungsdelikte, aber man kann dieses Urteil besonders als das konkrete Gefahrdungsdelikte verstehen. Der geschutzte Grad der Untreue ist im Zusammenhang mit dem ‘Vermogensschaden’, der nur im Untreue, d.h. das korStGB §355 Abs. 2 eigenartige bestimmt wird. Die bisherigen Rechtsprechung und die oben genannte Rechtsprechung alle schatzen dieses Vermogensschaden nicht nur ‘den wirklichen Schaden’ sondern auch ‘die Gefahrdung des wirklichen Schaden’. Im Fall der Aussetllung eigener Wechsel durch Missbrauch vom Vertreterbefugnis ist die oben genannte Rechtsprechung uber die Interpretation von dieser ‘Gefahrdung des wirklichen Vermoge nsschaden’ abweichend von der bisherigen Rechtssprechung. Im diesen Fall urteilt die bisherigen Rechtsprechung als der ‘Vermogensschaden’, also Maßstab der Vollendung “die Umlauf moglichkeit eigener Wechsel”. Dagegen urteilt die oben genannte Rechtsprechung ihn durch “die wirkliche Umlauf einger Wechsel”. Also diese Gefahr ist nicht allgemeine, unbestimmte Gefahr von Schaden, sondern kann man sie als “die schadensgleiche Vermogensgefahrdung” ansehen. Heute ist diese oben genannte Rechtsprechung in Uberlegung mit dem komplizierten und dynamischen geanderten Vermogensbegriff wunschenswert, und vor allem Untreueversuch, das inzwischen zu Formenbruch wurde, wiederhergestellt wird.

열처리된 세피올라이트를 이용한 수용액상의 혼합 중금속(Cd<SUP>2+</SUP>, Cu<SUP>2+</SUP>, Pb<SUP>2+</SUP>, Ni<SUP>2+</SUP>)의 제거

홍승희(Seung-Hee Hong),박성직(Seong-Jik Park) 대한환경공학회 2019 대한환경공학회지 Vol.41 No.7

저렴한 천연 규산염 광물인 세피올라이트는 중금속 제거효율을 높이기 위해서 고온에서 열처리되었다. 950℃에서 열처리한 세피올라이트(S950)의 Cd<SUP>2+</SUP>, Cu<SUP>2+</SUP>, Pb<SUP>2+</SUP> 및 Ni<SUP>2+</SUP>의 흡착량이 가장 높았다. S950의 혼합 중금속의 흡착특성을 규명하였다. 동역학적 실험은 5분 이내에 평형에 도달했다. S950의 평형 실험 결과에 Freundlich 모델이 Langmuir 모델보다 더 잘 부합되는 것으로 나타났다. S950에서 Cd<SUP>2+</SUP>, Cu<SUP>2+</SUP>, Pb<SUP>2+</SUP> 및 Ni<SUP>2+</SUP>의 최대흡착량은 각각 127.69 mg/g, 388.85 mg/g, 131.33 mg/g, 129.51 mg/g이었다. 열역학적 흡착의 결과, 중금속 흡착량은 반응 온도가 증가함에 따라 증가하였다. 열역학적 흡착은 S950으로의 중금속 흡착이 흡열 반응이며 자발적 반응인 것을 나타내었다. 이온 강도의 증가는 S950의 중금속 흡착을 감소시켰다. S950의 함량이 증가함에 따라 중금속 흡착량이 감소하고 총 제거율이 증가했다. 인산염의 존재가 S950의 중금속 흡착에 부정적인 영향을 미쳤다. Low-cost mineral silicate sepiolite was calcined at high temperature to increase its heavy metal removal efficiency. Sepiolite calcined at 950℃ (S950) showed higher adsorption amount of Cd<SUP>2+</SUP>, Cu<SUP>2+</SUP>, Pb<SUP>2+</SUP> and Ni<SUP>2+</SUP> than that of sepiolite calcined at other temperature. The adsorption characteristics of mixed heavy metals onto S950 were investigated. The kinetic experiment showed that equilibrium adsorption was reached with 5 minutes of reaction. Equilibrium experimental data were better suited to Frendlich model than Langmuir model. The maximum adsorption capacities for Cd<SUP>2+</SUP>, Cu<SUP>2+</SUP>, Pb<SUP>2+</SUP> and Ni<SUP>2+</SUP> in S950 were 127.69 mg/g, 388.85 mg/g, 131.33 mg/g and 129.51 mg/g, respectively. As a result of the thermodynamic adsorption, the amount of heavy metal adsorption onto S950 increased with increasing reaction temperature. Thermodynamic analysis showed that the heavy metal adsorption onto S950 was endothermic and spontaneous reaction. The increase in ionic strength had a negative effect on the heavy metal adsorption of S950. As the dose of S950 increased, the heavy metal adsorption amount decreased but the total removal percentage of heavy metals increased. The presence of phosphate negatively influenced heavy metal adsorption to S950.

Purpose: Ischemic stroke is rarely seen in children, but it could cause mortality and result in developmental disabilities such as motor paralysis, cognitive dysfunction, and epilepsy. In this study, the neurological outcomes of ischemic stroke in children were reviewed and the factors associated with the neurological outcomes were to be analyzed. Methods: Medical records of patients younger than 15 years of age who were newly diagnosed with ischemic stroke between January 2006 and December 2016 in Chonnam National University Hospital were reviewed. Results: This study consisted of 38 patients with ischemic stroke (male/female= 18/20, mean age=6 years 1 month±4 years 8 months). Neurological outcomes assessment was done at least 1 year after the onset of ischemic stroke. 10 patients (26.3%) had no neurological impairments. Motor paralysis was noted in 22 (57.9%), cognitive dysfunction was in 9 (23.7%), and epilepsy in 20 (52.6%). Among the possible risk factors for neurological impairments (age, sex, early seizures, characteristics of the infarcted lesions, abnormal electroencephalogram (EEG) findings), abnormalities on EEG findings were significantly associated with cognitive dysfunction (P=0.026) and the occurrence of early seizures with epilepsy (P=0.000). Conclusion: Neurological impairments were remained in 73.7% of children one year after ischemic stroke. Cognitive dysfunction was associated with abnormalities on EEG findings within 2 weeks after the onset of ischemic stroke and epilepsy with the occurrence of early seizures.

This study was performed to investigate relationships among night eating and nutrient intakes status in university students. A total of 271 subjects (male=155, female=116) were divided by using 3-days food record method according to the percentage of energy from night eating: non-night eating, <25% night-eating and ≥25 night-eating group. There were no significant differences in age, height, weight, percent body fat and BMI among the groups. The proportion of morning anorexia and insomnia was below 2% and 10%, and no differences were observed among the groups by percentage of energy from night eating. In the male subjects, the intakes of energy in the ‘≥25 night-eating group’ was significantly higher than those of the other groups; whereas, the nutrient density (ND, nutrient intakes per 1,000 kcal) and INQ (index of nutritional quality) of vitamin B1, vitamin B2, vitamin C, calcium and iron in the ‘≥25 night-eating group’ was significantly lower than those of the other groups. In the female subjects, the intakes of energy in the ‘<25 night-eating group’ was significantly higher than that of the ‘non-night eating group’. And the ND and INQ of vitamin C in the ‘<25 night-eating group’ was significantly higher than those of the ‘non-night eating group’. In addition, within the male subjects, the INQ of vitamin B₁, vitamin B₂, vitamin C, calcium and phosphorous showed significantly negative correlations with food intakes, energy intakes and percentages of energy from night eating after the values were adjusted for age. These results suggest that among male university students, night snack intakes above 25% of energy have lower micronutrient qualities of vitamin B₁, vitamin B₂, vitamin C and calcium.

인산염 제거를 위한 칼슘계 세피올라이트를 함침한 PVDF 비드의 제조

홍승희 ( Seung-hee Hong ),박성직 ( Seong-jik Park ) 한국수처리학회 2019 한국수처리학회지 Vol.27 No.3

Ca-Sepiolite is a natural mineral with high phosphate adsorption capacity. In this study, the adsorbents for phosphate were prepared by impregnating thermally treated sepiolite in polyvinylidene fluoride (PVDF) and its physical and chemical properties were investigated. The phosphate removal of sepiolite-impregnated PVDF beads with different sepiolite percentage were compared and optimized sepiolite percentage for the beads was found to be 30%. Further experiments were performed using 30% sepiolite impregnated PVDF (30SPL-PVDF). In the kinetic experiments, the adsorption rate of phosphate onto 30SPL-PVDF is governed by chemisorption. The maximum adsorption amount of 30SPL-PVDF was 26.87 mg/g. As the initial pH of the aqueous solution increased, the amount of phosphate adsorption decreased. The influence of anions on the phosphate adsorption followed in decreasing order: SO₄ ^2- > HCO₃ ^- > NO₃ ^-. The amount of phosphate removed per unit mass of 30SPL-PVDF decreased but removal percentage increased with increasing the amount of 30SPL-PVDF dose. In the column test, the breakthrough of phosphate started after about 600 hr of filtration, and the phosphate concentration of the effluent reached the influent concentration after about 1000 hr. It can be concluded that composites of sepiolite and PVDF, i.e., 30SPL-PVDF, can be used as filter media for the removal of phosphorus from aqueous solution.

Sepiolite is a natural mineral with high efficiency for phosphate removal but it can not be used as filter media due to its small particle size. Therefore, we suggested the used of sepiolite by inoculating it into cellulose acetate polymer beads. The polymer solution was prepared by dissolving cellulose acetate (CA) to acetate with their ratio 15:85 and 15% of poly ethylene glycol was added to the polymer solution. Experimental results show that the optimum amount of sepiolite inoculation was 30% (30_SPL-CA) and its adsorption amount of phosphate was 17.74 mg/g. Langmuir model was more suitable for describing phosphate adsorption onto 30_SPL-CA than the Freundlich model . As the temperature increased, phosphate adsorption was increased, indicating that phosphate adsorption was endothermic reaction. Phosphate removal efficiency was decreased with increasing pH. In column experiment, the breakthrough of phosphate was not observed for 60 hours in the column packed with 30_SPL-CA. The results of this study suggest that 30_SPL-CA bead can be used as an efficient water treatment material for phosphate removal.
