  • Objectives : To obtain necessary fundamental data for the development of oral health improvement programs for senior citizens in the manner of investigating the Status of their oral health. Methods : Data were collected from 346 senior citizens aged 65 years or older who had lived in Seoul and Gyeonggido province, Republic of Korea. This study was conducted for 3 months from April 2011 to June 2011. Excluding those obtained from 34 respondents who gave inadequate responses to given questions, the data from 312 respondents were analyzed. Results : 1. The number of senior citizens who chose 'Sometimes' to as an answer to the question about the self-perception of their own oral conditions such as mastication, swallowing, gingiva hemorrhage, dry mouth, and/or oral malodor was the largest. As an answer to the question about the presence of interpersonal avoidance, 'No' accounted for the largest proportion. The number of respondents choosing gingiva treatment regarding the perception of the necessity for medical interventions was the largest. 2. In regard to the knowledge of oral health care, the percentage of correct answers was the highest for 'I brush my tooth before each meal' ($0.69{\pm}0.156$), while the lowest percentage of correct answers was seen for 'Gingival diseases can be improved by medications' ($0.33{\pm}0.472$). Conclusions : Based upon the above mentioned results, the author conclude that developing relevant national programs and support policies at a national level as well as implementing proactive and systematic home-visiting oral health programs at the levels of local autonomous entities or communities will lead to significant improvements in senior citizens' oral health and QoL (quality of life).

  • The Optical Art is based on the principle of visual perception of the illusionary effects which induce psychological responses. It has influenced greatly on the Texile Design in that unique iJlusionary creativity of pattern simulates the visual sense of special movement; the dynamic psylosophy of vitalism. The Optical pattern has become a highly valued item due to its innovative effect in aesthetic direction. According to Vitor Vasarely the pioneer in this area, the integration and the inseparability of form and color which he calls 'Plastic Unity' provides the basis for the composition of infinite variety. The composition of infinite variety. The composition reveals the complex interaction between the space and form relating to order, repetition, combination and permutation. It is not simple to create optical patterns due to the extreme complexity composed by the multi-dimension and the infusion of form and color giving immensely varied movement. The purposes of this study are as follows; 1) to classify the complex processes of optical pattern on the basis of formative method. 2) to develop creative ideas for progressive contemporary textile design In this study, the analysis of applied methods is concentrated, which is based 1) on the gradual modification and on the transformation of the basic plastic elements which depend on thle direction of visual points involVing contradictory perspectives 2) on the composition varied special situations by repeating, overlapping and converging a series of idetUical units or by means of irrdiation, radiation and etc.

  • Subjects of the research were 668 elderly people aged over 65 from Gangneung city. OHIP 14 went through a first translation from English to Korean, discussion among experts, a second translation from Korean to English, and then the translation was approved. After the primary and main research were carried out, validity and correlation coefficient with the outcome of oral and mental health examination were studied. OHIP 14 in terms of the perception of oral health was relevant to the perception of overall health and oral health, the necessity of dental treatment, the satisfaction about oral health, the level of pain from observation, and the satisfaction about artificial tooth. OHIP 14 on account of oral health state was related to the number of present natural teeth, the necessity of dental treatment, and the status of no teeth. OHIP 14 according to overall health was correlated to the number of ailments, the state of mind, nerve systems, bones and sinews, digestive systems, urogenital systems, cerebrovascular systems, respiratory systems, eyes, ears, and dementia. OHIP 14 according to the perception of oral health showed a significant difference in the perception of overall health and oral health, the level of pain in terms of observation, and the satisfaction on artificial tooth. OHIP 14 on account of oral health state demonstrated a meaningful difference in the number of present natural teeth, the necessity of dental treatment, and status of no teeth. OHIP 14 in terms of overall health exhibited considerable difference in the state of mind, nerve systems, bones and sinews, digestive systems, cerebrovascular systems, respiratory systems, ears, and dementia. From the study, it was proven that there was relevance between the validity of OHIP 14 and the perception of oral health, the state of oral health, and the state of overall health in the experiment on some Korean elderly people.

  • The purpose of this study is to provide basic information on the current status of elementary school teachers' perception of gifted education. For this purpose, this study wi1l analyze elementary school teachers' perception of the gifted education (i.e., general perception of gifted education, characteristics of gifted children, identification of gifted children, programs for gifted education, and teachers of gifted education). A questionnaire survey was used for the purpose and research questions of this study. The questionnaire used in this study was constructed by taking into account the results of surveys conducted in previous studies and the literature on gifted education. Before conducting the research, a preliminary inquiry was made to identify problems that may occur while the subjects were participating in the survey, as well as to determine the appropriateness of the questionnaire and the amount of time needed. The preliminary inquiry was conducted with ten randomly selected elementary school teachers who did not participate as subjects in the actual research. The results were later used as initial data for the actual research. The subjects of this study were teachers who were teaching in8 elementary schools under each office of education in Seoul. This process was conducted for 180 elementary school teachers from April to May 2004. The results were analyzed using SPSS (Statistical Package for Social Science) Ver. 10.1, a software program for statistical research. After the data were analyzed, the following conclusions were arrived at: 1. The result of the genera1 perception of gifted education by elementary school teachers were positive and reasonably high. The level of their perception of detailed information or knowledge, however, was relatively low. 2. As for their perceptions of the emotional characteristics of gifted children, t11e results showed a low level of understanding of the characteristics of gifted children. 3. As for their perceptions of identification of gifted children, the results showed a high level of understanding of the appropriate time to provide special education to gifted children and of the methods to identify such. On the other hand, their understanding of the identification of gifted children in an actual class was poor. 4. The respondents' level of perceptions of programs for gifted education was very low since many subjects did not have any experiences with such programs. 5. The results showed a very positive response to receiving training on gifted education, though they were very reluctant to be assigned as teachers of gifted education because of the excessive work that is associated with such and their lack of capability in handling gifted children.

  • This study investigated the effects of brand awareness and perceived price fairness on the purchase intention of masstige brands and the moderating effect of country of advertising (Korea or China) for the Chinese tourists visiting Korea. Along with the luxury image and the reasonable price range of masstige brands, the effect of Korean models matching with the country of masstige brand and Chinese models for Chinese visitors was examined based on the construal level theory. To test the hypotheses, a 2 (brand awareness H/L)×2 (perceived price fairness)×2 (country of model) factorial design was employed. As a result, brand awareness and price fairness perception were found to have positive effects on the purchase intention of masstige brands, and the moderating effect of the country of advertising models was also significant. With Korean models, the effects of brand awareness and price fairness perception on the purchase intention of masstige brands were higher than with Chinese models. This study sheds light on the fact that for Chinese tourists, Korean advertising models are more effective even with the specific signal like price when they perceive psychological distance.

  • The anchovy, Engraulis japonica, were prepared with two different saltconcentration of 20%, 10% which was added 2, 5, 8 and 10 % of grind garlic(LSA 1, 2, 3, 4) and garlic juice(LSB 1, 2, 3, 4), respectively. The changes of such factor during fermentation of anchovy as general composition, salt concentration, titrable acidity and sensory evolution were analyzed. In addition, chewiness, taste, garlic flavor and off-flavor wastested it's results were belived that the more garlic amounts added the more rotten smell has been disappeared. In the view of sensory perception. sample of 90 days fermentation is supposed as the best period of fermentation. The contents of moisture and crude fat decreased while, those of ash and crude protein were changes little during fermentation of low salted anchovy. Titrable acidity decreased in all experiment groups during anchovy fermentation, its contents at 30 days fermentation were ranged between 1.4~ 1.8g/100g, but it dramatically decreased to 0.6~l.1g/100g at 90 days fermentation.

  • The aim of this study was to compare the physicochemical properties of domestic and imported commercial plain wheat flour and dough. Four types of domestic wheat flour (DW; DW1-4) were compared to four types of imported wheat flour (IW; IW1-4). DWs exhibited lower moisture content, lightness (L), and whiteness, and higher protein content, redness (a), and yellowness (b), than those exhibited by IWs. Solvent retention capacity of DWs and IWs was similar; however, DWs showed higher gluten performance index. Pasting properties, analyzed by rapid visco analyzer (RVA), were similar for DW1, DW2, and IWs; however, DW3 and DW4 showed different RVA patterns. Considering that DW3 and DW4 were organic wheat flour, possible incorporation of damaged kernel might increase amylase activities resulting in decreased peak viscosity. Dough resistance (108.4-159.9 g) and extensibility (11.8-16.7 mm) of IWs were higher than those of DWs (78.0-118.7 g, 8.7-12.5 mm, respectively).

  • Blue light (BL) induces stomatal opening through activation of H$^{+}$ pump, which creates electrical gradient across the plasma membrane for $K^{+}$ uptake into guard cells. The pump is the plasma membrane H$^{+}$ -ATPase and is activated via phosphorylation of the C-terminus with concomitant binding of the 14-3-3 protein. The opening is initiated by the perception of BL through phototropin (phot), which are recently identified as BL receptors in stomatal guard cells. In this study, we provide the biochemical evidence for phots as BL receptors in stomatal guard cells. vfphot was phosphorylated reversibly by BL, and phosphorylation levels of vfphot increased earlier than those of the plasma membrane W-ATPase. BL-dependent phosphorylations of vfphot and H$^{+}$-ATPase showed similar fluence dependency. Staurosporin, an inhibitor of serine/threonine protein kinase, and diphenyleneiodonium chloride (DPI), an inhibitor of flavoprotein, inhibited BL-dependent phosphorylations of vfphot and H$^{+}$ -ATPase. These results indicate that vfphot acts as a BL-receptor mediating stomatal opening.l opening.
