This study investigated the experience and practice of elementary school students on nutrition education. The data were collected from 217 male and female students attending 5-6th grade elementary schools in Seoul and Kyunggi-Do from March to June 2007, interviewing face to face by a nutrition teacher and 3 interns of a nutrition teacher. The results were as follows: 86.5% of the subjects learned about ‘Table etiquette’, ‘Reasons for eating fruits and vegetables’ (78.7%), ‘Food waste and environment’ (72.3%), ‘Healthy snacks’ (55.7%), ‘Food sanitation’ (52.3%), ‘Food culture of foreign countries’ (48.1%). Nutrition education experience was significantly different by gender. A total of 43.5% boys responded that they never learned about ‘basic food preperation’ (p < 0.01). They had learned ‘Nutrients for body’ and ‘Food waste and environment’ in school, ‘Healthy weight loss’, ‘Food culture of foreign countries’, ‘Food circulation’ on television, Most content (‘Table etiquette’, ‘Simple cooking’, ‘Food sanitati n’, ‘Eating behaviors for health’, ‘Reasons for eating fruits and vegetables’, ‘Healthy snacks’) was learned from parents. The practice after nutrition education was higher in ‘Table etiquette’ (2.14), ‘Eating fruits and vegetables’ (2.07) than others compared with education experience. The most reason of non-practice on nutrition information was ‘Troublesome’. In ‘Nutrients for body’, a boy answered ‘Difficult for practice’ 20.0%, a girl answered ‘Difficult to understand’ 32.6%, showing a significant difference between the gender groups (p < 0.001). They remembered the ‘Nutrients for body’ (49.6%), ‘Food sanitation’ (44.5%) because of ‘important content’,‘Basic food preparation’ (40.6%), ‘Food culture of foreign countries’ (36.3%) because of ‘interesting content’, ‘Healthy weight loss’ (52.0%), ‘Eating behavior for health’ (44.5%) and ‘Healthy snacks’ (33.7%) because of ‘need for my health’.

도현주,김성열,안종성,하영주,이승찬,오재택,장명호,정홍석,문홍모,박해준 大韓免疫學會 1996 大韓免疫學會誌 Vol.18 No.3

To investigate the role of adjuvant for cytotoxic T lymphocytes (CTL) induction, squalene-based adjuvant was studied its capability eliciting to the induction of cellular immunity as well as humoral immunity to exogeneous proteins. Ovalbumin (OVA) was used as model proteins. It was demonstrated that antigen formulation consisted of metabolizable oil squalene mixed with Tween 80 and pluronic L121 (S/TJ121) could induced the antigen specific CTL responses and antibodies irrespective of immunization routes in mice. We also demonstrated that this antigen formulation was a inducer of CD8+, major histocompatibility complex(MHC) class I-restricted, and antigen-specific C;1'Ls. These data suggest that the squalene-based emulsion system is a potent adjuvant inducing cellular immunity as well as humoral immunity.

The purpose of this study is to establish a production system for providing fresh leafy garlic in winter season and to obtain data for an easy method of indoor nutriculture of this plant, especially in apartment life. 1. Emergence rates in 15℃ and in 20℃ cultured by Hyponex and by tap water were 100% after 7 and 21 days from planting in Shenyang cultivar, a Southern ecotype, and in Cheju cultivar, a Southern ecotype respectively. Euisung cultivar, a northen ecotype, did not planting uner 15℃ until 7 days from planting, but emerged 85% and 95% after 21 days from planting under 15℃ and 20℃ conditions, respectively. 2. Plant lengths were higher in 20℃ and in Hyponex culture than in 15℃ and in tap water culture, respectively. Shenyang cultivar in 15℃ and 20℃ cultured by Hyponex and tap water ceased to eloongate the leaf and showed chlorosis after 35 days from planting, but Cheju and Euisung cultivars continued to elongate the leaf. The plant length of Shenyang cultivar was especially long as compared with other two cultivars and grew fast. 3. After 21 days from planting, leaf number, diameter of leaf sheath, leaf weight and weight of leaf sheath were higher in 20℃ and in Hyponex culture than in 15℃ and in tap water culture. respecively. Among three cultivars, Shenyang had much more leaves and heavy ones. 4. Comparative crop growth rate(CGR) showed at maximum after 7 days from planting in 15℃ and in 20℃ cultured by Hyponex and by tap water in Shenyang and Cheju cul-tivar while after 14 days from plamting in Euisung cultivar, then decreased gradually afterward. The CGR at maximum was higher in 20℃ and in Hyponex culture than in 15℃ and in tap water cul-ture, respectively. 5. The percentage of contribution of CGR to leaf were increased until 21 days from planting, then decreased gradually afterward in Shenyang and Cheju cultivars, but Euisung showed continu-ous increase. The percentage of contribution of CGR to root declined markedly after 14 days from planting in all three cultivars. 6. Leaf area index(LAI) were high in all three cultivars in 20℃ in Hyponex culture as compared with tap water culture. After 28 days from planting, LAI was 2.0 and 1.0 in Cheju and in Euisung cultivar respectively, comparing with above 4.0 in Shenyang cultivar. 7.

Electrical quadruple hysteresis in Pd-doped vanadium pentoxide nanowires due to water adsorption

Kim, Byung Hoon,Oh, Soon-Young,Yu, Han Young,Hong, Won G,Yun, Yong Ju,Kim, Yark Yeon,Kim, Hae Jin Elsevier 2010 SCIENCE AND TECHNOLOGY OF ADVANCED MATERIALS Vol.11 No.6

<P>Humidity-dependent current–voltage (<I>I–V</I>) characteristics of Pd-doped vanadium pentoxide nanowires (Pd-VONs) were investigated. Electrical quadruple hysteresis (QH) was observed and attributed to the large amount of water molecules adsorbed on the nanowires. Using QH in Pd-VONs, the reaction of water with PdO was interpreted as the water molecules are desorbed and then dissociated with increasing bias voltage. Owing to the dissociated H<SUP>+</SUP> and OH<SUP>−</SUP> ions, PdO is reduced and oxidized. As a result, water molecules recombine as the bias voltage is decreased.</P>

Lee, Hye Ah,Kim, Young Ju,Lee, Hwayoung,Gwak, Hye Sun,Park, Eun Ae,Cho, Su Jin,Oh, Se Young,Ha, Eun Hee,Kim, Hae Soon,Park, Hyesook Walter de Gruyter GmbH 2013 Journal of pediatric endocrinology & metabolism Vol.26 No.9

<P>Background and Objective: We aimed to investigate the association between serum 25-hydroxyvitamin D (25(OH)D) and anthropometric indicators of adiposity among Korean preadolescent children aged 7?9 years. Subjects and Methods: Children aged 7 to 9 from the Ewha Birth & Growth Cohort were followed up from July to August 2011. Serum 25(OH)D concentration was measured using radio immunoassay. We assessed the magnitude of cross-sectional association with vitamin D concentrations and indicators of adiposity [body mass index (BMI), waist circumference (WC), mid-arm circumference (MAC), body fat mass (BFM), percent body fat (PBF), and triceps skinfold thickness (TSF)] using multiple linear and logistic regression analyses adjusted for sex, age, birth order, maternal education, and fruit/fruit juice intake. Results: Thirty-two (16%) out of a total of 205 children showed an optimal level of serum 25(OH)D, but most children did not reach a sufficient level (<30 ng/mL) even in summer. The level of 25(OH)D was inversely associated with BMI (β=?0.10, p<0.01), WC (β=?0.28, p<0.01), and BFM (β=?0.12, p=0.02) after adjusting for confounding factors and showed marginal boundary with PBF (β=?0.20, p=0.06) and TSF (β=?0.11, p=0.08). Regarding the risk of overweight, a 13% protective effect per 1 ng/mL increase of 25(OH)D was shown even after adjusting for relevant confounding factors (adjusted odds ratio=0.87, 95% confidence interval 0.78?0.98). Conclusions: We found that the 25(OH)D concentrations were inversely associated with adiposity indices in preadolescent children. This study suggests that adequate vitamin D intake in growing children is crucial to maintain an optimal vitamin D level to prevent obesity and obesity-related health problems later in life.</P>

Yu-Jin Kim,Sang-Hee Lee,Yeon-Ju Lee,Hae-In Oh,Hee-Tae Cheong,Boo-Keun Yang,Seunghyung Lee,Choon-Keun Park 한국수정란이식학회 2015 한국동물생명공학회지 Vol.30 No.1

The objective of this study was to investigate the efficiency of nicotinic acid on sperm cryosurvival and fertilization ability in frozen-thawed boar semen. Boar semen was collected by glove-hand method and was frozen using freezing solution treated to 0, 5, 10 and 20 mM of nicotinic acid. The frozen sperm for sperm characteristic analysis was thawed such as viability, acrosome reaction, and mitochondrial integrity. The frozen-thawed sperm was estimated by SYBR14/PI double staining for viability, FITC-PNA/PI double staining for acrosome reaction and Rhodamine123/PI double staining for mitochondrial integrity using a flow cytometry. The embryo was estimated in vitro development and DCFDA staining for reactive oxygen species assessment. As results, frozen-thawed sperm viability was significantly higher in 5 and 10 mM (61.1 ± 1.5%, 64.7 ± 2.0%) of nicotinic acid than other groups (0 mM, 52.1 ± 2.3%; 20 mM, 47.8 ± 5.1%, P<0.05). The live sperm with acrosome reaction was significantly higher in 5 and 10 mM of nicotinic acid (26.1 ± 1.8%, 24.9 ± 1.5%) than other groups (0 mM, 35.3 ± 0.8%; 20 mM, 36.5 ± 1.9%, P<0.05). The live sperm with mitochondrial integrity was significantly higher in 5 and 10 mM (84.2 ± 3.6%, 88.4 ± 2.3%) of nicotinic acid than other groups (0 mM, 77.3 ± 4.4%; 20 mM, 73.3 ± 3.6%, P<0.05). Blastocyst rate of in vitro development was significantly higher in 10 mM (17.0 ± 1.3%) of nicotinic acid than other groups (0 mM, 9.4 ± 0.5%; 5mM, 12.6 ± 0.8%; 20 mM, 5.0 ± 1.0%, P<0.05). Moreover, total cell number was higher in 5 and 10 mM (53.6 ± 2.9%, 57.9 ± 2.8%) of nicotinic acid than other groups (0 mM, 41.0 ± 1.4%; 20 mM, 23.2 ± 2.8%, P<0.05). Hydrogen peroxide in embryos was lower in 5 mM nicotinic acid (0.7 ± 0.1%) than other groups (0 mM, 1.0 ± 0.1%; 10mM, 0.9 ± 0.0%; 20 mM, 1.4 ± 1.0%, P<0.05). In conclusion, nicotinic acid-treated semen improves cryosurvival and quality of spermatozoa. Also, the fertilized oocytes with nicotinic acid improve quality of embryo and blastocyst formation.

Purpose: This study was done to provide support material to traditional nursing interventions through investigation of the effect of Auricular acupressure therapy for female staff in the hospital who have dysmenorrhea but cannot be absent from work even with severe symptoms affecting their work and therefore cannot get proper pain management. Method: The participants in this study were 62 women were working in the G-university hospital in Jin-ju, assigned to experimental (30) and 32 control groups (32). The study method was a quasi-experimental, nonequivalent control group non-synchronized design. The experimental group received acupressure treatment (a pin was attached to tape) on the special stimulation points in the inside of the ear, 5 times for 5 seconds, morning, afternoon, and night. Tape without the pressure pin was applied to the same points for women in the control group to evaluate placebo effect. Data were collected from May to November 2007 and were analyzed using SPSS PC+ 12 version. Descriptive statistics, t-test, x2 -test, Fisher's exact test, paired t-test, were used to analyze the data. Results: The experimental group showed a significant decrease in dysmenorrhea compared to the control group (t=-2.743, p<.01). In the sub-part, the experimental group showed menstruation related pain (t=-3.726, p<.01), menstruation related to behavioral change (t=-2.421, p<.05) and symptoms however, there was no significant difference related to attention deficit, water retention, and negative image. Conclusion: Application of auricular acupressure therapy was approved for this study and although auricular acupressure therapy was not effective for all of the symptoms, it was effective for dysmenorrhea.
