The purpose of this study was to investigate the sensibility image of necktie according to width and color combination of checked pattern. The experimental materials developed for this study were a set of stimulus and response scales. The stimuli were 18 color pictures, in which the width(small: 0.2cm, medium: 1cm, large: 2cm), tone combination(similar, contrast), and hue combination(WR: white+red, WB: white+blue, WG: white+gray) were manipulated. The 7-point scale was used for evaluation of sensibility image. The subjects of this research were 216 female college students living in Gyeongnam. The investigation was carried out at September 2009. The data were analyzed by using SPSS program. Analysis methods were ANOVA and Duncan-test. The results of this study were as follows.; The analyses of sensibility for necktie according to width and color combination of checked pattern revealed that the concerned factors are five characteristic dimensions of attractiveness, youth, appeal, elegance, and warmness. Width showed an independent effect on appeal. Tone combination showed an independent effect on attractiveness, appeal, elegance, and warmness. Interaction effects of width and tone combination on attractiveness were found. Hue combination showed an independent effect on all dimensions. In addition, significant interaction effects of width and hue combination on attractiveness, youth, appeal, and elegance were found. Significant interaction effects of tone combination and hue combination on attractiveness, youth, and appeal were found.

The mission of National Health Screening Program for Infant and Children is to promote and improve the health, education, and well-being of infants, children, families, and communities. Although the term 'diagnosis' usually relates to pathology, a similar diagnostic approach applies to the child seen primarily for health supervision. In the case of health, diagnosis determines the selection of appropriate health promoting and preventive interventions, whether medical, dental, nutritional, educational, or psychosocial. Components of the diagnostic process in health supervision include the health 'interview'; assessment of physiological, emotional, cognitive, and social development (including critical developmental milestones); physical examination; screening procedures; and evaluation of strengths and issues. Open and informed communication between the health professional and the family remains the most significant component of both health diagnosis and health promotion. Families complete medical history forms at their health supervision visit. Family-friendly questionnaires, checklists, and surveys that are appropriate for the child's age are additional tools to improve and update data gathering. This type of information helps initiate and inform discussions between the family and the health professional. This article provides a comprehensive review of current National Health Screening Program for Infant and Children in Korea.

This study examines the effects of reading and story sharing through fairy tales on young children's character development in their role play using natural materials. To achieve this, 40 5-year-old children at early childhood educational institutes in Daejeon were tested 16 times for 8 weeks. The results were as follows. First, their role plays using natural objects through reading and talking had a positive effect on their personality cultivation. Second, there was no experimental difference in their prudence and filial piety of basic behavioral items, but their cleanliness and patience were proven effective in the experiment. Third, all their justice, conscience and service indicating their sociality-related friendship, kindness, gentleness and morality were proven effective in the experiment, which their role plays using natural objects through reading and story sharing through fairy tales had an educational effect on improving their sociality and morality through peer interaction. This suggests that their mind to improve social virtues with an exchange of emotions, particularly, treat natural role play in a friendly way, their public promises to cherish life, and their ethical virtues to obey the rules in the process of consideration, appreciation, understanding and help through mutual communication and cooperation in forest experience activities are very effective from an educational perspective.

The importance of marine pollution prevention is increasing day by day both at home and overseas. Against this context, this study proposes policy directions to forge an improved system of coastal control for local governments. I have analyzed the coastal pollution response capacity of local governments to find out how the central government can better support these efforts to reinforce capacity. For the purposes of this research, I carried out a number of case studies on large-scale marine pollution accidents that occurred at home and abroad. According to the results, I identified the implications of the coastal pollution response capacity of local governments and suggested several alternatives such as construction of step by step response system, strengthening education and training, part of human network activation, establishment of grounds for securing response resources, and establishment of dedicated department to prepare for potential future marine pollution accidents. However, as little research has been done on the coastal pollution response capacity of local governments, this work may be regarded as an experimental study to help facilitate follow-up research in the future.

A quantitative restriction of maternal diet without changes in quality of diet was given to the Sprague Dawley rats during the third week of gestation and lactation. Half the normal average daily intake of control group was given to deficient groups in this period. Female rats of control group were fed a commercial diet ad libitum throughout the experimental period. Dietary restriction started from birth to weaning in deficient I group and from the 15th day of gestation to weaning in deficient II group. Body and brain weight of offsprings of deficient groups were significantly lower than control group, but the ratios of brain weight to body weight in deficient groups were higher than the control group. Significant difference between deficient groups (I and II) was noticed at weaning. Brain DNA, RNA and total protein of offsprings of deficient groups were significantly lower than control group, but RNA/DNA, brain weight/DNA, and total protein/DNA show that cell number were more affected than the cell size by the maternal dietary restriction during the third week of gestation and lactation. Between the deficient groups, there was a significant difference in brain DNA and RNA, but no significant difference in total brain protein.

In this study, abiotic transformation of 1-naphthol(1-NP) via oxidative-coupling reaction and its reaction products were investigated in the presence of Mn oxides. The reaction products were characterized for their relative polarity using solvent extraction experiment and reverse-phase HPLC, and for structure using CCMS and LC/MS, and for absorption characteristics using UV-Vis spectrometry. The reaction products present in aqueous phase were more polar than parent naphthol and comprised of 1,4-naphthoquinon(1,4-NPQ) and oligomers such as dimers and trimers. Hydrophilic component present in water phase after solvent$(CH_2Cl_2)$ extractions was identified as naphthol polymerized products having molecular weight(m/z) ranging from 400 to 2,000, and showed similar UV-Vis. absorption characteristics to that of foil fulvic acid. Transformation of 1,4-NPQ, which is non-reactive to Mn oxide, to the polymerized products via cross-coupling reaction in the presence of 1-NP was also verified. In this experimental conditions(20.5 mg/L, 1-NP, 2.5 g/L $MnO_2$, pH 5), the transformation of 1-NP into the oligomers and polymerized products were about 83% of initial 1-NP concentrations, and more than 30% of the reaction products was estimated to be water insoluble fractions, not extracted by $H_2O$ methanol. Results from this study suggest that Mn oxide-mediated treatment of naphthol contaminated soils can achieve risk reduction through the formation of oligomers md polymer precipitation.

As a carbon-free, green growth alternative, internal and external interest in hydrogen energy and technology is growing. Hydrogen was added to co-axial methane, methane-propane, and methane-propane-ethane diffusion flames, which are the main ingredients of LNG, to evaluate its effect on flame formation and combustion products. The variation in combustion products produced by adding hydrogen gradually to diffusion pyrolysis at room temperature and normal pressure conditions was observed experimentally by using a gas analyzer, and the shape of diffusion pyrolysis was observed step by step using a digital camera. The experimental results showed that the production volume of nitrogen oxides tended to increase and became close to linear as hydrogen was added to the diffusion pyrotechnic. This is because the relatively high temperature of heat insulation and fast combustion speed of hydrogen facilitated the production of thermal NOx. On the other hand, CO2 production tended to decrease as hydrogen was added to reduce the overall carbon ratio contained in the mixed diffusion flame of methane, methane-propane, and methane-ethane-propane. This means that the mixed fuel use of LNG-hydrogen in ships may potentially reduce emissions of CO2, a greenhouse gas.

The purpose of this study is to investigate the effects of flash panorama-based virtual field trips (VFT) as a supporting tool for geological field activity on middle school students' spatial visualization ability, conceptual understanding, and perceptions. A total of 17 middle school students participated in a three day long actual geological field trip around Jeju Island where a three-phase instructional model is applied for utilization of flash panorama-based VFT, which was proposed by Kim and Lee (2011). With one-group pretest-posttest pre-experimental design, data were collected using questionnaire and were analyzed to find out a change in students' spatial visualization ability and volcanic concept understanding, and their perceptions about the utilization of flash panorama-based VFT. Findings are as follows: First, the effect of utilizing flash panorama-based VFT in actual field trip revealed that there was meaningful increase in 'spatial relation' category of spatial visualization ability and 'knowledge' and 'comprehension' domains of volcanic concept understanding. Second, majority of students showed positive gain index in both spatial visualization ability and volcanic concept understanding. Lastly, participating students showed much interest and high satisfaction, and positive perception on the use of VFT. They also perceived that the utilization of flash panorama-based VFT could help in carrying out an actual field trip in terms of cognitive and geographical factors.
