Purpose: The aim of this study was to evaluate the process and outcome of a mobile computerized system for individual home visiting healthcare. Methods: A nonequivalent control group non-synchronized design was employed for this study. The newly constructed system was administered to 80 healthcare providers in the experimental group for 8 weeks. Data were analyzed using descriptive analysis, t-test, and ANCOVA with the SPSS 18.0 program. Results: In the process stage, the difference in the frequency of computerized information usage between the experimental and control groups was significant as $8.88{\pm}3.20$ and $7.08{\pm}2.92$, respectively (t=3.90, p<.001). In the outcome evaluation stage, all kinds of healthy lifestyle such as alcohol use, nutrition, weight management and mental health were not improved. Conclusion: The findings of this study showed that the revised mobile computerized system was an effective device for individual visiting healthcare providers. Further advanced strategies for using this system should be developed and applied in a broad range of community healthcare.

We present a simple and easy-to-implement lumped stiffness model to elucidate the load transfer mechanism among all individual tube shells and intertube van der Waals (vdW) interactions in transversely compressed multi-walled carbon nanotubes (CNTs). Our model essentially enables theoretical predictions to be made of the relevant transverse mechanical behaviors of multi-walled tubes based on the transverse stiffness properties of single-walled tubes. We demonstrate the validity and accuracy of our model and theoretical predictions through a quantitative study of the transverse deformability of double- and triple-walled CNTs by utilizing our recently reported nanomechanical measurement data. Using the lumped stiffness model, we further evaluate the contribution of each individual tube shell and intertube vdW interaction to the strain energy absorption in the whole tube. Our results show that the innermost tube shell absorbs more strain energy than any other individual tube shells and intertube vdW interactions. Nanotubes of smaller number of walls and outer diameters are found to possess higher strain energy absorption capacities on both a per-volume and a per-weight basis. The proposed model and findings on the load transfer and the energy absorption in multi-walled CNTs directly contribute to a better understanding of their structural and mechanical properties and applications, and are also useful to study the transverse mechanical properties of other one-dimensional tubular nanostructures (e.g., boron nitride nanotubes).

Since Lau and Murnighan first introduced the concept of faultlines in 1998, there are many extended studies related to faultlines theory. It is obvious that faultlines theory adds valuable explanations in addition to what numerous previous demographic studies have explored. However, previous research has not been able to fully integrate the characteristics embedded in the workplace environments, and the influence of faultlines in IT industries has yet to be explored. So it is not reasonable and convincing to extend the findings from previous faultlines research to other industries in the global world. In this study, IT related influence is given considerable weight into traditional faultlines theory and the impact of IT-based faultlines is revealed. Our study indicates that IT-based faultlines have negative impact on task conflict, process conflict and relationship conflict, and also have negative impact on individual outcomes such as individual performance and satisfaction. The influence of IT-based faultlines on people s intend to remain in the current organization is found to be insignificant. Our empirical study reconfirmed that faultlines are important indicator in group works and also that faultlines are intimately related to various conflicts and individual outcomes. We hope our research findings would be beneficial to the organizations concerned with effective and efficient group work.

Perforated vinyl mulching technique was performed on Pleurotus sajor-caju beds to assess fruitbody formation. Individual fruitbody of P. sajor-caju was transformed into bunch type on vinyl mulching bed. It was effective to grow the mushroom without waterlogging and abortion of small pins on the beds as well as hygienical bed management. A bunch showed 79 fruitbodies and 225 g of weight. Available site for fruiting was reduced up to 20% in comparison of 100% for conventional bed. The color of fruitbody turned on brownish white from treated vinyl mulching bed.

In parametric approach to a signature verification, it generally uses so many redundant features unsuitable for each individual signature that it causes harm, instead. This paper proposes a method of determining personalized weights of a feature set in signature verification with parametric approach by identifying the characteristics of each feature. For an individual signature, we define a degree of how difficult it is for any other person to forge the one's (called 'DFD' as the Degree of Forgery Difficulty). According to the statistical characteristics and the intuitional characteristics of each feature, the standard features are classified into four types. Four types of DFD functions are defined and applied into the distance calculation as a personalized weight factor. Using this method, the error rate of signature verification is reduced and the variation of the performance is less sensitive to the changes of decision threshold.

The long-tailed, positively skewed exponential distribution can be made into an almost symmetric distribution by taking the exponent of the data. In these situations, to use the traditional shewhart control limits on an individuals chart would be impractical and inconvenient. The transformed data, approximately bell-shaped, can be plotted conveniently on the individuals chart and exponentially weighted moving average chart. In this paper, using modifying statistics with transformed exponential of the data, we give a method for constructing control charts. Selecting method of exponent for individual chart is evaluated. And consider that smaller weight being assigned to the older data as time process and properties and taking method of exponent($\theta$), weighting factor($\alpha$) are suggested. Our recommendation, on the basis result of simulation, is practical method for EWMA chart.

The demand for residential space is encompassing diverse ranges to keep pace with the times. Due to the Increase in wealth, people today want more functional and physical well being as well as giving more weight to the emotional aspect in spatial planning. This study paid special attention on the psychological effect of color--especially difference of warm/cold temperature--and the individual variation on favorable colors. 1. For a communal space (e.g. living rooms), subjects showed high preference of YR range of colors and warm colors. 2. For an individual space (e.g. bedrooms), subjects showed high preference of GY range of colors and neutral colors. 3. For a sanitary space (e.g. bathrooms), subjects showed high preference of PB and B ranges of colors, and cold colors. 4. For all of the above spaces, subjects showed high preference of warm colors.

This paper introduces the concept of temporary utopia, which is private rather than communal and individual rather than collective, to investigate a paradoxical relationship between longing and loss in the individuals' utopian process. The main argument is grounded in Ernst Bloch's critical theory of utopia, which gives more weight to its function and process rather than its form and destination, which is the opposite of the traditional utopian imagination. The notion of temporality as utopic-spatial consequences is illustrated with a case study of New Malden's North Korean community in London, United Kingdom. Through the examination of North Koreans' utopianism, it amplifies how the individual memories, emotions, and longings are re-created, re-built and re-imagined in the form of temporary utopias to incorporate the endless ideals and changing conditions of the individuals. This investigation sheds new light on urban ethnic enclaves as utopia in the realm of architecture and urbanism.

Among current health-related issues, obesity is considered one of the foremost, and the importance of this subject has fostered a national interest in body weight loss. In this study, the differences in recognition of body weight loss according to age and gender are investigated. The subjects of the study were 720 (male: 360 and female: 360) aged between 10-60 years, who had experienced to try body weight loss during 6 months prior to this study. Anthropometrics, general characteristics, personal reasons for body weight loss, comprehension of body weight loss, and a knowledge of diet-related issues were assessed through a questionnaire. The anthropometric measurements showed significant differences in height, body weight (present and desired) and BMI (p < 0.05) by age and gender. The difference between desired body weight and actual body weight was greater for younger subjects or female, regardless of whether they had under- or normal body weight (p < 0.05). Reasons for body weight loss varied; younger subjects and female tended to lose body weight "to enhance their appearances", whereas the older subjects and male desired "to improve their health" (p < 0.05). Subjects had different concepts concerning body weight loss; younger subjects and female considered body weight loss as "maintenance of a slender figure, or becoming more lean". On the other hand, older subjects and male thought body weight loss to be "effects approaching normal body weight" (p < 0.05). From our studies, it can be concluded that attitude on concerning body weight loss varied according to a age and gender. Thus, consideration of this individual differences would be vital in developing contents of a particular nutritional education program for body weight loss.
