  • Recently, great advance is achieved in the field of genome-wide functional screening using cell-based assay. Here, we briefly introduce well-established and typical cell-based assays of GPCR and some parameters which should be considered for genome-wide functional screening. Because of characters and importance of GPCR as drug targets, several ways of assay systems were devised. Among them, high-content screening (HCS) that is based on the analysis of image by confocal microscope is becoming favorite choice. The advances in this technology have been driven exclusively by industry for their convenience. Now, it is turn for academy to define more detail signaling networks via HCS using cDNA or siRNA libraries at genome-wide level. By isolating novel signaling mediators using cDNA or siRNA library, and postulating them as new candidates for therapeutic target, more understanding about life science and more increased chances to develop therapeutics against human disease will be achieved.

  • Nitrosative stress is defined as pathophysiological conditions that are related to covalent modifications of proteins by nitration/nitrosylation by forms of nitrogen oxide ($NO_x$), leading to DNA damage, ultimately, cell death. This type of stress condition appears to be associated with a number of disease states, including diabetes, inflammation and neurodegenerative diseases. Since these pathological conditions are frequently chronic in nature and, thus, require long-term treatment, changes in pharmacokinetics are likely to affect the therapy. Transporters are membrane proteins that facilitate the movement of substrates, including drugs, across plasma membranes of epithelial / endothelial cells. Since it is now increasingly evident that transporters are pharmacokinetically significant, functional alteration of transporters by this stress condition may have therapeutic relevance. In this review, experimental techniques that are used to study both in vivo and in vitro nitrosative stress are summarized and discussed, along with available literature information on the functional implication of transporters under conditions of nitrosative stress conditions. In the literature, both functional induction and impa irment were apparently present for both drug transporter families [i.e., ATP-binding cassette (ABC) and solute carrier families (SLC)]. Furthermore, a change in the function of a certain transporter appears to have temporal dependency by impairment in the early phase of nitrosative stress and induction thereafter, suggesting that the role of nitrosative stress is complex in terms of functional implications of the transporters. Although the underlying mechanisms for these alterations are not fully understood, protein nitration/nitrosylation appears to be involved in the functional impairment whereas transcript factor(s) activated by nitrosative stress may play a role, at least in part, in functional induction. Interestingly, functional induction under conditions of nitrosative stress has not been observed for SLC transporters while such impairment has been documented for both ABC and SLC transporters. Further investigations appear to be necessary to fully delineate the underlying reasons for these differences on the impact and importance of nitrosative stress conditions.

  • The purpose of this study was to examine the actual state of cooking wine usage, and analyze the relationship between the attributes of cooking wine and demographic characteristics. The major findings of this study are as follows. First, the origin and correct choice of cooking wine were significantly related to hotel type, restaurant type and career. Second, the importance of the taste and aroma of a cooking wine, which are intrinsic attributes in the evaluation of a wine, had significant relationships with all the demographic variables whereas the importance of purchase cost and label information of the cooking wine only exhibited a significant correlation with career (p<0.05). Third, 53.7% of the respondents used cooking wine based on recipes, while the rest used it by rule of thumb. These results between restaurant type were significantly different (p<0.05). For the results of this research to be of more use, further research should be conducted on the functional aspects of cooking wine and their effects on cooking. In addition, further systematic research should be performed on the functional and sensory effects of a variety of wine tastes and aromas on cooking.

  • This study aims to investigate the effect of the selection attribute of Newtro (New + Retro) product marketing, which is a recent topic in the food industry, on consumer satisfaction. Newtro marketing, also known as Newtro-style marketing, is a marketing strategy that emerged in South Korea, particularly in the food industry. Newtro marketing aims to appeal to consumers' nostalgia for the past while incorporating contemporary elements. As a research method, a survey was conducted on the importance of selection attributes and repurchase intention of Newtro food for consumer groups of various age groups ranging from teenagers to those in their 40s or older. To analyze the demographic content of the sample, frequency analysis of the SPSS statistical package was performed, and structural equation modeling was performed using the AMOS program for confirmatory factor analysis and discriminant validity analysis. The analysis results are as follows. First, Package Design, Perceived Healthiness, and Emotional Taste, optional attributes of Newtro marketing, significantly affected satisfaction. Second, satisfaction was found to have a statistically significant effect on repurchase intention. However, Functional Flavor did not statistically affect satisfaction. This study empirically analyzed the importance of consumers' selection attributes for the recently popular food Newtro marketing and suggested implications.

  • This study was conducted to develop a theoretical model for the determinants of activities of daily living in Korean rural elderly people. The theoretical model was derived from Lawton's Ecological Model to explain human behavior. The model includes determinant variables for functional status such as age, sex, physical status, cognitive status, physical environment, social environment, and depression. Data for this study was collected from 189 elderly people in a rural district near Chonju City. The data was analyzed with SPSS PC/sup +/4.1 and LISREL 8. The analysis of the data showed that the first proposed theoretical model did not fit the collected data well. In order to increase the fit of the model to the data, the model was modified by deleting the exogenous variables of sex, physical environment, and social environment. The fit of the modified model to the data was increased and was move suitable. The results of this study show that the determinants of the activities of Korean rural elderly people were age, perceived physical condition, cognitive status, and depressional status. Age has a significant direct and indirect effect on the activities of daily living of rural elderly people. Perceived physical condition has a significant indirect effect through depression on activities of daily living. Cognitive status also has a significant indirect effect through depression on functional status. Depression has a significant direct effect on the functional status. Physical environment and social environment showed reversal relationships to functional status. In conclusion, the results of this study show that personal characteristic factors are more important than environmental characteristic factors for functional status of elderly people. However, the importance of depression to functional status in Korean rural elderly people and the reverse relationship between social environment and functional status, reflect Korean specificity. Korean nursing needs to focus more on this Korean specificity in order to develop nursing knowledge and practice appropriate to Korean people.

  • Distal extension partial dentures are supported by both the relatively rigid teeth and the resilient mucosa. So impression techniques of residual alveolar ridge in case of distal extension partial denture have particular importance in order to broad distribution of the masticatory force. McLean recognized the need for recording the tissues supporting distal extension partial denture base in functional form to equalize the resilient and non-resilient support, and this was called functional impression. Many investigators proposed various techniques of the functional impression for a distal extension partial denture, but only a little studies were performed about displacement of soft tissue under distal extension partial denture base. The purpose of this study is to investigate the amount of vertical displacement of the soft tissue under distal extension partial denture base by different functional impression techniques. Impression techniques used were Z.O.P. Impression, Selective Tissue Placement Impression, Functional Relining Impression. Measurement of the vertical displacement of soft tissue were made with Depth Gauge and Measuring Platform. A Anatomic Impression was used as a control. The results were tested statistically using 3 way ANOVA and Scheffe test. The followings were the results obtained from this study. 1. The greatest amount of soft tissue displacement was observed in the center of the retromolar pad. 2. No significant differences were found between the crest of alveolar ridge and the buccal shelf area. 3. The greatest soft tissue displacement was observed in Functional Relining Impression using Iowa wax, and the least displacement was observed in Selective Tissue Placement Impression using murcaptan rubber base. 4. No significant differences were found between finger pressure and biting pressure in Z.O.P. Impression, but greater displacement was observed by biting pressure than finger pressure in Functional Reling Impression.

  • The purposes of this study were to investigate difference on recognition, preference, satisfaction and possession of functional textile clothing in psychological comfort groups according to gender and age of the elderly and suggest optimal physical, mental and healthy functional textiles for the elderly. The data was collected from 262 respondents in their age of over 55, who lived in Busan. SPSS 21.0 was used and t-test, cross tabulation analysis, frequency analysis, and descriptive analysis were performed for analysis. The results are as follows. First, high groups of psychological comfort for both gender and age of the elderly showed higher recognition and preference of functional textiles, especially in the high groups of the new silver generation and women. Second, the high groups of psychological comfort for both gender and age of the elderly showed higher satisfaction of functional textiles. However, it was lower than preference of functional textiles. Last, the possession of major clothing function over all the elderly was comfort, fitting motion adaptability, and health safety function in order. Low groups of psychological comfort possessed fitting motion adaptability textile clothing more than the high groups, and the high groups of psychological comfort possessed comfort and health safety textile clothing more than low groups. In conclusion, this research showed the importance of functional textiles for the elderly in terms of psychological comfort as well as the need for healthy comfort textiles for the advanced activities of daily life.

  • These days mobile phone which were used mainly by grown-up persons are now widely used among children as well due to new social demands. Despite this trend, existing mobile phones are still being designed and produced according to the taste of people in their 20s and 30s, even the elderly, not satisfying physical, emotional and cognitive characteristics raised by children. This study aimed to extract the design factors of mobile phones for children by reflecting functional factors requested by children and parents in QFD's customer demands. First, functional and design factors requested in mobile phones for children were extracted from existing products and documentary records and some functional factors were selected through a process of integration and omission. The survey research was conducted on children and parents, based on the selected functional factors. Based on the survey research, functional factors were analyzed using AHP, and key functional factors considered by children and parents in mobile phones for children were investigated. Finally, in order to reflect the results in QFD, the correlation between functional factors and design factors was constructed as HOQ through experts' evaluation. The results showed that both children and parents recognized the basic functions such as telephoning, text messaging and phone directory as high priority functional factors, even though the relative importance was different between children and parents. Therefore, it is likely to satisfy the desires of both children and parents by designing mobile phones for children in consideration of design factors such as menu depth, button independence and button arrangement. It is expected that this study will promote experiments on design factors and propose basic data for and guidelines to mobile phone design for children.
