The aim of this research is to examine patterns of design governance used by Northern European countries to respond to social crises and understand design governance as a tool for sophistication of social services and social integration. Design governance as applied in Sitra of Finland, MindLab of Denmark and the Gulliver project of Germany encourages using design methodology for analyzing and solving problems related to social phenomena based on involvement of the private, public, industrial, and academic groups. Especially, the citizens are actively involved in developing problem-solving ideas and designing new policy with other governance members, rather than simply providing information or one-time participation. In the cases discussed in this study, design governance reduce unnecessary administrative and financial consumption and inconvenience caused by complicated rules, based on field-oriented approach, regional characteristics, pluralism, and respect for diversity. Therefore, future design policy paradigm will need to evolve into concept of policy design and pluralistic monitoring centered on design governance based on participation of private sector to lead policy development, from the current system in which only few officials decide policy.

This study examined the effects of interpersonal relationship harmony and stress coping on the college adjustment among nursing students. The participants were 231. Data were analyzed using descriptive statistics, t-test, ANOVA, Pearson correlation coefficients, and multiple regression. Adjustment to college life significantly correlated with interpersonal relationship harmony and stress coping style. Interpersonal relationship harmony was significantly different according to year, satisfaction with nursing as a major, and academic achievement. Multiple regression analysis showed that interpersonal relationship harmony and stress coping(problem-focused, emotion-focused, hopeful thought) explained 23% of variance in adjustment to college life. The study findings suggest that intervention intended to promote nursing students' adjustment to college life should focus on improving interpersonal relationship harmony and stress coping.

As Korea has approached the aging society, older Koreans have become an important force in restaurant sales today. To succeed with this silver market, it is important for restaurant managers to know who they are and which factor influence the older Koreans' eating-out decision making process. The purpose of this study was to investigate the effect of the elderly consumers financial independency on restaurant selection process. Data were collected from 178 older consumers above 55 years old and analyzed using the descriptive statistic analysis, MANOVA, and one-way ANOVA. The results showed that the elderly consumers financial independency significantly influenced the decision making process in determining where they eat out Significant differences were found between high income group and low income group in the Problem Recognition Step(Wilks' Lambda=0.776, F=3.796), Information Search Step(Wilks' Lambda=0.779, F=2.959), Alternative Evaluation Step (I :Wilks' Lambda=0.835, F=1.748/ II :Wilks' Lambda=0.764, F=3.212), and Purchase Decision Step(Wilks' Lambda=0.849, F=2.412), except the Post-Purchase Behavior(Wilks' Lambda=0.933, F=1.179). The more financially independent older consumers were, the more directly they were involved in the eating out decision making process. Older consumers with higher income and more personal property were likely to 'propose to eat out by themselves'(F=10.986), to obtain restaurant information from the 'printed materials'(F=9.707), to consider 'convenient location' as most important factor when they eat out(F=5.594), and to go to 'family restaurant'(F=7.067), 'Japanese restaurant'(F=7.391) and 'fine dining restaurants'(F-=6.382). In conclusion, we found that the elderly consumers financial independency did influence the eating-out decision making process. Considering that older Korean will become a financially independent consumer and will be eating away from home more often, food service operations should actively position themselves for this market and develop the market-driven menus and services to meet their needs and expectations.

This is an underlying study for expanding child growth and developmental screening program, which had been implemented as a part of maternal child health service in a certain public health center located in P City. This study attempted to develop system model to discover, consult and follow-up developmental disabilities in children in early stage. For the purpose of providing groundwork for further development of screening program, the system model was analyzed and evaluated. One of the focuses of this study was developing practical tool that can aid small number staffs of public health center to handle large number of patients. 9 types of developmental checklist by key month was developed to support understaffed public health center. These checklists were also supplied to other public health centers, greatly improving qualitative and quantitative development of screening project. Also, the 4-step program of operating and managing child growth and developmental screening was proved to be quite effective. Total 632 children were evaluated and 21 of them were suspected to have developmental problem. Among these children, 8 children were determined to receive regular supervision of public health center. Other 13 children were recommended to visit professional institution, but only 7 of them actually visited institution. Four of these children who visited professional institution are currently receiving treatment, while the other 3 children were determined to require close observation. Five times of screening education were provided to the staffs in public health center and personnel in charge of children in every district public center in P City. The purpose of this training was to improve individuals' capability to implement project and to establish basis for expanding child growth and developmental screening program. The participants were guided to have continuous attention for the project, and their knowledge, skill and recognition were greatly improved through educational training. Also, professional child consulting and education, including lecture for baby food and baby food menu exhibition, were given to parents. Through this opportunity, parents acquired higher understanding about baby food while the local residents' recognition for maternal child health service was greatly improved.

In recent years, most automobile manufacturers have been using slim light source images to imprint their own brand image and identity. A light guide type lamp is widely used for making these kinds of a slim light source image. A light guide lamp means using a light emitting diode light source at one end of a long cylindrical pipe. The light from the light emitting diode source moves through the pipe by total reflection principle. Moving light is sent forward by various optic structures which is applied in the cylindrical pipe. However, the light guide lamp has a problem that the image of the light differs depending on the viewing direction, and in some cases there is dark section. It means light guide has low quality about lighting image. In this paper, trying to improve the fundamental problems of the light guide mentioned above by using various triz methods. Through functional modeling, estimating the factors affecting the light in the light guide lamp and make various ideas to improve the lighting image using the chain effect cause analysis, function oriented search scientific database techniques. Using these kinds of various TRIZ methods, finally find solutions that can improve the brightness and lighting uniformity of the light guide lamp. The ideas obtained in this paper were applied to actual vehicle development, and several patents achievements were obtained. In conclusion, it is proved that TRIZ method is useful for making ideas in actual automobile industrial field and is also a useful method for acquiring patent.

Peptide identification in tandem mass spectrometry is usually done by searching the spectra against target databases consisting of reference protein sequences. To control false discovery rates for high-confidence peptide identification, spectra are also searched against decoy databases constructed by permuting reference protein sequences. In this case, a peptide of the same sequence could be included in both the target and the decoy databases or multiple entries of a same peptide could exist in the decoy database. These phenomena make the protein identification problem complicated. Thus, it is important to minimize the number of such redundant peptides for accurate protein identification. In this regard, we examined two popular methods for decoy database generation: 'pseudo-shuffling' and 'pseudo-reversing'. We experimented with target databases of varying sizes and investigated the effect of the maximum number of missed cleavage sites allowed in a peptide (MC), which is one of the parameters for target and decoy database generation. In our experiments, the level of redundancy in decoy databases was proportional to the target database size and the value of MC, due to the increase in the number of short peptides (7 to 10 AA). Moreover, 'pseudo-reversing' always generated decoy databases with lower levels of redundancy compared to 'pseudo-shuffling'.

A simplified analytical procedure is presented to estimate the reduction of elastic lateral stiffness of steel moment frames arising from the radius-cut dogbone weakening. With the original radius-cut dogbone shape, it is almost impossible or too complicated to integrate analytically the mathematical expressions encountered when applying the conjugate beam method to compute the beam deflection component. In this study, the problem is circumvented by replacing the original radius-cut dogbone with an equivalent dogbone of constant width. The equivalence between the two is established by imposing an equal dogbone elongation criterion. This approach is justified by using a calibrated finite clement analysis. Then, the elastic lateral deflection components from the column, panel zone, and beam are derived for a typical beam-column subassembly. The derived results can be used to evaluate the reduction of the frame lateral stiffness. Case studies conducted within some practical ranges of frame configurations show that the reduction in frame lateral stiffness due to the presence of dogbone cut is on the order of 1 to 2 percent and is reasonably negligible in practical sense.

The Taylor expansion expresses a differentiable function and its coefficients provide good approximations for the given function and its derivatives. In this study, m-th order Taylor Polynomial is constructed and the coefficients are computed by the Moving Least Squares method. The coefficients are applied to the governing partial differential equation for solid problems including crack problems. The discrete system of difference equations are set up based on the concept of point collocation. The developed method effectively overcomes the shortcomings of the finite difference method which is dependent of the grid structure and has no approximation function, and the Galerkin-based meshfree method which involves time-consuming integration of weak form and differentiation of the shape function and cumbersome treatment of essential boundary.

A problem of many fractal image compression algorithms providing good quality at low bit rate is that the decoding time rests on an iterative procedure whose complexity is imag-dependent. This paper proposes an iterative-free fractal image decoding algorithm to reduce the decoding time. In the proposed method, under the encoder previously with the same codebook image as an initial image to be used at the decoder, the fractal coefficients are obtained through calculating the similarity between the codebook image and an input image to be encoded. As the decoding time could be remarkably reduced. For verifying the validity and universality of proposed method, We evaluated and analyzed the performance of decoding time and image quality for a number of still images and a moving picture with different distributed characteristics.

Today, modern people perceive skin care as part of their physical health care, and acne is a common skin disease problem that is found on the face. In this paper, an effective acne detection algorithm using CIE $L^*a^*b^*$ color space has been proposed. It is red when the pixel value of the component image $a^*$ is a positive number, so it is suitable for detecting acne in skin image. First, the skin image based on the RGB color space is subjected to light compensation through color balancing, and converted into a CIE $L^*a^*b^*$ color space. The extracted component image $a^*$ was normalized, and then the skin and acne area were estimated with the threshold values. Experimental results show that the proposed method detects acne more effectively than the conventional method based on brightness information, and the proposed method is robust against the reflected light source.
