  • A nutrition education program for teachers and caregivers of the preschool children can be most effective when it is based on a comprehensive needs assessment dealing with sociodemographic factors, dietary habits, and nutrition. The purpose of the present study was to investigate current dietary habits and nutrition knowledge of the teachers and caregivers of the day-care centers. Two hundred forty two teachers and caregivers were administered a questionnaire which was designed to ascertain informations on sociodemographic data, dietary habits and nutrition knowledge. Dietary habits of the teachers were found to be significantly different by sociodemographic variables; breakfast skipping/meal irregularities (age, p=0.011); frequency of snacking (education level p=0.031); preference for salty taste(age, p = 0.000, marital status p=0.038); preference for sweet tarte (age p=0.009); preference for vegetables (income level p=0.050); frequency of eating out (age p=0.028, marital status p=0.001); frequency of coffee drinking (age p=0.019). Daycare center teachers' nutrition knowledge level was found to be less than adequate expecially on nutrients that are liable to be deficient in young growing children and their food sources. Proportions of the teachers who answered correctly to the questions on foods rich in vitamin A, iron content of milk, bioavailability of calcium in plant foods were as low as 20.2%-54.5%. The most frequently used sources of nutrition information were mass media such as TV, radio, newspaper and magazines. Only 2.9% of the subjects reported that they obtain nutrition information from health professionals such as nutritionists/dietitians, physicians, and nurses. These findings are applicable at the planning and implementation stages of various nutrition programs for the improvement of dietary habits and nutrition knowledge of the teachers and caregivers of the daycare centers. Further studies are needed to investigate the effects of teachers' dietary of habits and nutrition knowledge on food habits of young growing children.

  • Automated weather stations were installed at 9 locations with, three different elevations, (i.e., 50m, 100m, and 300m a.s.l.) with different slope and aspect in a small watershed ($50km^2$ area). Air temperature at 1500 LST and solar radiation accumulated for 1100-1500 LST were collected from January to December 2012. Topography of the study area was defined by a $30{\times}30$ m digital elevation model (DEM) grid. Accumulated solar irradiance was calculated for each location with the spatially averaged slope and aspect of surrounding circles with 5, 10, 15, 20, 25, and 30 grid cell radii, respectively. The 1500 LST air temperature from clear sky conditions with zero cloud amount was regressed to the 1100-1500 LST solar irradiance at 9 locations. We found the highest coefficient of determination ($r^2$ = 0.544) at 25 grid cell radius and the temperature variation in this study was explained by Y = 0.8309X + 0.0438, where Y is 1500 LST temperature (in $^{\circ}C$) and X is 1100-1500 LST accumulated solar irradiance (in $MJ/m^2$).

  • Background : The roles of antioxidants in the placenta and genetic susceptibility to oxidant chemicals in relation to neonatal birth weight have not been elucidated. We determined whether the level of placental manganese superoxide dismutase (MnSOD) and its genetic polymorphism plays any role in oxidative stress and neonatal birth weight. Methods : We measured placental MnSOD and determined MnSOD genetic polymorphism among 108 pregnant women who were hospitalized for delivery and their singleton live births in Korea. Main outcome measurements are maternal urinary malondialdehyde (MDA) and birth weight. Results : Maternal urinary concentrations of MDA were significantly associated with neonatal birth weight (P=0.04). The enzyme level of placental MnSOD was also significantly associated with MDA concentration (P=0.04) and neonatal birth weight (p<0.01). We observed dose-response relationships between placental MnSOD and maternal urinary MDA, and neonatal birth weight after adjusting for maternal weight, height, age, and neonatal sex. After controlling for covariates, MnSOD variant genotype increased maternal urinary MDA concentrations (p<0.01) and reduced birth weight by 149 gm (P=0.08). Conclusions : This study demonstrates that the placental level of MnSOD during pregnancy significantly affects fetal growth by reducing oxidative stress, and that genetic polymorphism of MnSOD probably modulate the effects of oxidants on fetal growth.

  • A consumer survey was conducted for the subject of a total of 503 housewives in Korea, with the questionnaires on the quality attributes for Korean native chicken. The responding results collected were used for the importance-performance analysis of the quality attributes involved in production, processing, distribution, and consumption of Korean native chicken. The quality attributes with both relatively high importance and performance ("keep up the good work") were chicken origin, shelf life, freshness, and safety issues, while those with high importance but low performance ("concentrate here") were chicken breed certification and refrigerated/ frozen state. Respondents were also interested in lean meat and protein content of the chicken meat. In the aspect of eating quality attributes, chewiness was the most important one. The survey shows tenderer, chewier, and more flavorful chicken meat will be preferred and a new chicken breed with those eating quality attributes needs to be developed.

  • Contrast media may cause tissue injury by extravasation during intravenous automated injection during CT examination. Here, we present a study in which contrast media extravasation was detected and localized in the neck and thorax by three-dimensional(3D) CT data reformation. The CT studies of the extavasation site were performed using a 3D software program with four different display techniques axial, multi planar reformation(MPR), maximum intensity projection(MIP), and volume rendering displays are currently available for reconstructing MDCT data. 3D image reconstructions provide accurate views of high-resolution imaging. This paper introduces extravasation with the MDCT and 3D reformation findings of contrast media extravasation in neck ant thorax. The followed injection of the external jugular vein into an existing intravenous catheter and a large volume of extravasation was demonstrated on by 3D MDCT.

  • In this study, we tried to design and synthesize using natural polymers (hyaluronic acid and sodium alginate) and also to make some kinds of scaffolds as sponge type for reducing the burst effect of loaded drug from them. Photo-dimerizable group was incorporated to hyaluronic acid and degradable hydrogel was prepared by the UV radiation of the polymer. The pore size and its distribution of scaffold were controlled by changing microsphere production conditions such as solution concentration and spraying pressure. It was found that drug release behavior from synthesized scaffolds was affected by hybridization of two naturally originated polymers (cinnamoylated tetrabutylammonium hyaluronate: CHT and cinnamolylated sodium alginate: CSA) and the obtained scaffolds were degraded in fairly long time (about 2 months) under in vitro environment. Therefore, we expect that obtained scaffolds can be applicable for the tissue regeneration scaffolds in the fields of orthopaedic surgery.

  • The purpose of this study was to develop royal costume design with contemporary taste depending on the character of hero, Lee San, and time flow of TV historical drama and research design discrimination and creative expression. As study methods, the literature study using books and theses concerning costume, fine art, culture and history were used for theoretical background and the empirical study method manufacturing actual costume on the basis of literature and relic were used for dress manufacture. The design concept of costume was modern & chic & clean. The costume was designed through straight silhouette, clean & bright colors excluding prime colors, style transformed to permanent straight pleats on the basis of chulik, 100% silk material focusing on high quality and pattern & decoration of the age of Three Kingdoms. As results, the designs of princess' official rob, day dress and chulik, and emperor's official robe, chulik, military dress and chun-dam-bok were developed. The design discrimination depending on social status change. In the period of princess, black, white, silver and blue were used but in the period of emperor, red, gold and black were used. It was expressed through dragon pattern and extended length used in cloth. The design discrimination depending on character change was visualized through color. Although it is not consistent with historical investigation, contemporary fashion design elements were added to royal costume through color contrast of black & white, permanent straight pleats, velcore, wristlet, extended length and layered-look.

  • This paper confirms characteristics of lead isotopes of bronze artifacts excavated from Korea peninsula using 673 data classified according to Age, type and region. Lead isotopes data in Early iron ages are distributed in the southern Korean peninsula, but data in Joseon ages are concentrated in zone 3. Also Bronze artifacts excavated from Seoul, Gyeonggi, Chungcheong, Jeolla and Gyeonsang are manufactured using raw materials of the entire Korea peninsula, but bronzes excavated from North Korea aren't produced using raw materials of Gyeonsang provinces. Lead isotopes data will be able to find moving routes of raw materials and to separate the period of mixing and recycling of lead.

  • The purpose of this study was to classify, from collected home health care records data, nursing diagnoses according to the NANDA system and nursing interventions according to the NIC system, and to link nursing interventions to nursing diagnoses. For this study, 101 home health care records of clients seen between September, 1994 and November, 1996 at Yonsei Medical Center, Seoul, were analyzed. The results of this study are summarized as follows : 1. The most frequent nursing diagnoses were ‘Risk for infection’ and ‘Altered nutrition : Less than body requirements’, then ‘Impaired skin intergrity’ and ‘Ineffective airway clearance’ in the Exchange pattern of NANDA nine human response patterns. 2. The most frequent nursing interventions were the interventions in the Physiological : Complex domain, there were 690(50.7%) interventions among a total 1347 interventions. This results corresponds to Yom, Young Hee(1995)’s research, both Korean and U.S. nurses used the interventions in the Physiological : Complex do main most often on a daily basis. And respiratory nursing interventions were most frequent because 32.7% of the subjects were respiratory patients. 3. The next step was to link the nursing interventions to nursing diagnoses. The most frequent nursing diagnosis was ‘Risk for infection’ and 19 interventions for ‘Risk for infection’ were used 267 times. Then 14 interventions for ‘Impaired skin integrity’ were used 258 times, 12 interventions for ‘Ineffrective airway clearance’ were used 193 times, 12 interventions for ‘Altered nutrition : Less than body requirements’ were used 122 times, 10 interventions for ‘Activity intolerance’ were used 75 times, and 11 interventions for ‘Knowledge deficit’ were used 52 times. 4. The use of standardized classification in the areas of nursing diagnoses and nursing interventions facilitates clinical decision making and prompt nursing activity, and so enhances the effectiveness of nursing care.

  • Purpose: This study aimed to investigate the educational needs of research ethics among nursing researchers. Methods: Convenience sample of 161 nursing professors and 262 master or doctoral nursing students participated in the study. Data was collected with self-reported questionnaire from June to August 2009, and analyzed with descriptive statistics using SPSS WIN (version 14.0). Results: Among 161 nursing professors, about 31.7% has educated nursing ethics in the postgraduate course. The most common course was nursing research or methodology (62.7%), and median education time was 2 hr. Areas that showed difficulty in understanding was the conflict of interest and plagiarism for professors and falsification and fabrication for graduate students. Average knowledge on the research ethics was 75.4 points for professors and 61.6 points for students based on the 100 points. Conclusion: Educational needs of research ethics among nursing professors and students in the postgraduate course was high. We recommend both basic and advanced research ethics educational programs for the nursing researchers. The basic course should be at least 6 hr and include various cases and something to discuss.
