The purpose of this analysis is to investigate the effect of leading characters in picture books on self concept in children. For this study, we selected a total of 55 picture books, all of which were best sellers in four internet book stores. The method used for the study was based on content analysis. The results of this analysis were as follows: First, the gender of leading characters was male more often than female, and the majority of picture books were creative story books and translation books. Second, subordinate parts related to the self-concept were most frequently found in the social self-concept. Social self-concept was positively expressed through the relationship between friend and family characters in story books. Cognitive self-concept was the least. Third, when the frequency of positive and negative expressions in picture books was analyzed, the social self-concept was found to be positively expressed in the subordinate parts of relationships between friends and family. The social self-concept was negatively expressed, however, in the subordinate parts of relationship between non-significant others, and the emotional self-concept was also negatively expressed in the subordinate parts of the emotional recognition and expression. In summary. instances of cognitive self-concept and positive expression were found to be more significant than negative ones.

This study aims to test empirically whether the ASEAN Corporate Governance Scorecard (ACGS) has a positive effect on Sustainability Reporting (SR) and whether the ACGS and Sustainability Reporting (SR) have a positive effect on Firm Value (FV). The study was conducted in five ASEAN countries - Indonesia, Malaysia, Singapore, Philippines, and Thailand from 2014 - 2017. The research sample was collected from companies with the ACGS data and obtained with the help of 359 company observations. Hypothesis testing was performed using the Ordinary Least Square (OLS). The results of the study do not support all hypotheses. The ACGS has no effect on sustainability reporting. The ACGS has a significant negative effect on firm value, while sustainability reporting has a negative and insignificant effect on firm value. The ACGS and sustainability reporting are not good news for investors. This research's limitation is that companies rarely disclose the final value of the ACGS in their annual reports, so this research uses content analysis. The weakness of content analysis is the researchers' subjectivity so that the point of view between researchers is different. Besides, sustainability reporting for several ASEAN countries is voluntary, so not all companies can be sampled, which ultimately affects interpretation.

The recent increase in the production of 3D contents allowed viewers to experience various 3D contents. However, some of the viewers did not experience 3D depth well. Several researches were done in past to measure viewers' 3D depth perception, but these researches were done with certain limitations. In this paper, we measured viewers' 3D depth perception and recovery rate in relation with the changes in binocular disparities, saturation, and brightness values after subjects' watching 2D/3D contents. The results showed that when viewers watched the 3D content with positive binocular disparities for 42 minutes, viewers felt that the object seemed to have moved further forward than it was before; with 3D content with negative binocular disparities, viewers felt that the object seemed to be moved backwards. We found that the locational differences of the object in positive disparities were greater than those in the negative binocular disparities. The recovery rate was computed by comparing two measured values of before and after watching 3D contents for 30 minutes. On average, after 30-minute break, viewers showed roughly 50 % of recovery rate.

GMO labeling system in South Korea stipulates three labeling methods: GMO labeling, no labeling and Non-GMO labeling. Products labeled as Non-GMO are not allowed for unintentional commingling of GMO without tolerance. However, consumers vary their acceptance of Non-GMO label on the unintentionally commingled products and willingness to pay according to the mixing rate, rather than devalue the whole products as useless. Additionally, consumers do not believe that the acceptable mixing rate should be discriminated between non-labeled products, which allow up to 3% of unintentional GMO contamination, and Non-GMO labeled products. Information on unintentional GMO mixing mainly refers to the mixing rate, but the Non-GMO content remaining even after commingling is also important information. The decline in value is alleviated when consumers are exposed to positive information, such as Non-GMO content, rather than when exposed to negative information, such as the mixing rate. Loss Aversion Coefficient is relative depending on whether the information representing the loss is positive or negative. Information that a Non-GMO labeled product contains X% GMO is more sensitive than information that (100-X)% Non-GMO remains.

본 연구는 성인여성을 대상으로 자기존중기억 내용의 주제를 알아보기 위해 수행되었다. 자기존중기억(self-esteem memory)이란 자기에 대해 현저하게 긍정적으로 또는 부정적으로 생각했던 사건에 대한 기억을 말하는데, 성취에 관한 내용과 관계에 관한 내용으로 대별될 수 있다. 연구 참가자는 청년기 여성(M=21.56) 18명, 중년기 여성(M=54.13) 15명, 노년기 여성(M=74.35) 20명으로 총 53명의 성인여성이었으며, 긍/부정적 자기존중기억을 각 4가지씩 총 8가지를 회상, 구술하도록하여 그 내용을 주제별로 분류하고 살펴보았다. 분석 결과, 성인여성은 긍정적인 자기존중기억과 부정적인 자기존중기억 모두 성취보다는 사회적 관계에 관한 내용에 초점이 맞추어져 있었으며 그러한 경향은 청년의 긍정적 기억에서 또 중년의 부정적 기억에서 발견되었다. 이는 개인이 강조되는 서양문화와 비교해 집단주의적 성격이 중시되는 우리 문화 특성과 공동체적 특질이 두드러진 여성의 특성을 반영한다고 할 수 있다. 추후에 자기존중기억의 주제에 대한 성차 및 생애 주기별 차이에 대한 연구가 필요하다.

The present paper focuses on the interaction between lexical-semantic information and affective prosody. More specifically, we explore whether affective prosody influence on evaluation of affective meaning of a word. To this end, we asked participants to listen a word and to evaluate the emotional content of the word which were recoded with affective prosody. Results showed that first, emotional evaluation was slower when the word meaning is negative than when they is positive. Second, when the prosody of words is negative, evaluation time is faster than when it is neutral or positive. And finally, when the affective meaning of word and prosody is congruent, response time is faster than it is incongruent.

Zephyranthes candida, Narcissus pseudonarcissus and Crinum asiaticum pollen were placed near their pistil parts respectively on agar cultural media(microslides) containing 10% sucrose and 100mg/l botic acid plus 1% agar with or without calcium and some other calciumsupporting inorganic salts. If fresh pistils (100% moisture) were used pollen grew toward their pistil parts, showing "positive" tropism. This was also true when combinations among three different species were made. Pollen tubes grew away from the pistils if they were dried (below 10% moisture), showing "negative" tropism. Pollen could not show any tropic growth and thus grew at random of all directions if the pistil parts were incompletely dried (approximately 50% moisture). The similar tropic responses of pollen-tube growth with the three species could be demonstrated with etiehr wet or dried tooth-pick segments. Calcium jons in the basic medium merely promated pollen-tube growth and so either "positive" or "negative" tropism became rather distinctive, but they were not tropically active. Pollen tubes grow toward pistil parts with more moisture content and seem to be hydrotropically sensitive. This was assumed due to the cohesive force existing in water molecules.esive force existing in water molecules.

This study was carried out to find out the content of injurious heavy metals, such as mercury, lead, cadmium and arsenic of marine fish which had been captured in adjacent sea of Korea. From March, 1 to April, 30 in 1993. 60 sample of fishes were collected the adult fish and young fish. These samples were analyzed by the Mercury Analyzer and Inductively Coupled Plasma Emission Spectro Analyzer. The results of the study were summarized as follows: (1) The content of mercury in Therafra chalcograma was 0.112$\pm$0.034 ppm which was higher than other fishes, but Pseudosciaena manchurica and Pampus argenteus had lower (P<0.05). Although lead content of Trichiurus lepturus was 0.359$\pm$0.056 ppm, which was higher than other fishes. The lead content of Theragra chalcograma had lower to the almost same level. The cadmium content of the Theragra chalcograma was 0.069$\pm$0.010 ppm which was higher than other samples, but Pseudosciaena manchurica had 0.039$\pm$0.020 ppm to lower level. Though there was some fluctuation in the arsenic content which was 0.433~3.752 ppm, the arsenic content of Therafra chalcograma was 3.752$\pm$2.873 ppm which was the higher than any other fishes. But there are not statistical significances. (2) Heavy metal content by the maturity of the fishes: Mercury content of the old Pseudosciaena manchurica was 0.055$\pm$0.15 ppm comparing to the young's result of 0.030$\pm$0.009 ppm (P<0.05). Though there were some differences according to the maturity, but thee was no statistical significance. (3) In view of the correlation of the heavy metal content, for Pseudosciaena manchurica, high correlation was founded to r=0.6437 between mercury and cadmium (P<0.05). Though the content of mercury, arsenic cadmium and lead had positive correlation (r=0.2725) and negative correlation (r=-0.3958), but there was no significance at all. The other fishes were not found correlation between the heavy metal content. Positive correlation was found between age with mercury in Pseudociaena manchurica (r=0.7018, P<0.05). The negative correlation of age with lead content in the Pseudociaena Manchurica was signigicant (P<0.05). The correlation coefficient was r=-0.7623. The age with mercury content in Coloabis saira had high correlation (r=0.7201, P<0.05). Through the above analysis, it can get conclusion that injurious heavy metal content of the fishes in Korea such a mercury, lead, cadmium and arsenic were at the level of natural content. At present, guidelines of maximum residue level allowed at foreign countries about the injurious heavy metal have been used according to the kinds of fish but our government guideline for the marine fishes in only total mercury below 0.7 ppm and lead below 2 ppm. So more aggressive guidelines for the allowance level of heavy metals in marine fishes are required for the safety of foods.

The aim of this study was to investigate the relation of sensory quality traits of cooked beef to fresh meat quality and histochemical characteristics, especially muscle bundle traits, in the longissimus thoracis muscle of Hanwoo steers. Cooking loss negatively correlated with softness, initial tenderness, chewiness, rate of breakdown (RB), and amount of perceptible residue (AR) after chewing (p<0.05), and drip loss showed negative correlation with RB and AR (p<0.05). All the attributes of tenderness exhibited negative correlation with the Warner-Bratzler shear force value (p<0.05). Marbling score and the intramuscular fat (IMF) content showed positive correlation with all the organoleptic characteristics, including tenderness attributes, juiciness, and flavor (p<0.05). Regarding histochemical characteristics, muscle fiber size did not have a significant correlation with all the sensory quality traits, although the area percentage of type I fiber was related with softness, initial tenderness, and chewiness (p<0.05). On the contrary, the characteristics of muscle bundle were related to all the sensory tenderness attributes (p<0.05), and the sensory tenderness increased with smaller muscle bundle size (p<0.05). These results suggest that the IMF content and bundle characteristics can be used as indicators for explaining the variations in sensory tenderness in well-marbled beef.

Uniform nanofibers of polyurethane with different content of Juniperus Chinensis extracts (JCE) were successfully prepared by the electrospinning method. We investigated physiochemical properties of prepared compound nanoweb according to various concentrations of Juniperus Chinensis extracts using a Fourier transform infrared (FT-IR) spectrometer, X-ray diffractometer (XRD), thermogravimeter (TGA), and differential scanning calorimeter (DSC). The antibacterial activity of the JCE loaded PU nanofiber was conducted using the disk diffusion test against Gram-positive and Gram-negative bacteria. JCE was induced in the infrared spectra in the absorption band of PU/JCE nanowebs at $3,300cm^{-1}$, $2,960cm^{-1}$, $1,400-1,600cm^{-1}$, and $1,050cm^{-1}$. Thermal stability decreased with increasing JCE content in the PU/JCE nanowebs. The DSC curve of the PU nanoweb shows an endotherm peak at $420^{\circ}C$; in addition, the peak also became smaller and broader with increasing JCE content. The diffraction intensities of PU observed at 2 theta of $20^{\circ}$ decreased with the increasing amount of JCE in the compound nanoweb. In addition, the crystal intensities of the compound nanowebs also decreased along with the JCE content. Structural analysis indicates that JCE and PU are miscible. Juniperus Chinensis incorporated PU nanofibers demonstrated excellent antibacterial properties against both Gram-positive and Gram-negative bacteria.
