The aim of this study is to identify the value structure of active seniors for noodles. Noodles are the secondly most preferred and familiar food in Korea, followed by rice. And noodles also have a variety of tastes/flavors and even a variety of ceremonial characteristics. The necessity of offering proper food to seniors has recently increasing because Korea becoming an aged society. This study conducted 1:1 in-depth interviews with 30 active senior participants using the soft laddering technique, which is based on the means-end chain theory. The Implication Matrix and HVM were derived from performing content analysis. The active seniors mainly consider the 'taste', expecting to obtain the 'satisfying taste', and pursuing the 'family affair', 'pleasure', and 'self-satisfaction'. The results of this study indicated that the taste is the most important attribute and the active seniors consider their family as well as the pleasure and satisfaction of their own. Male seniors mainly pursue the 'pleasure' and 'self-satisfaction' by satisfying their taste through considering 'taste' and 'familiarity'. But female seniors mainly pursue the 'family affair' by 'satisfying taste' through considering 'taste'. These results can be used as a basic data for developing noodle products for the elderly. This study will also contribute to the development of special care food and product concepts for the silver generation.

Background: The converging epidemics of tuberculosis (TB) and end-stage renal disease (ESRD) have generated a significant public health burden, however, previous studies have been limited to a small number of patients. This nationwide cohort study aimed to assess the rate of developing active TB among patients receiving dialysis for ESRD. Methods: The Korean national health insurance database was used to identify patients receiving dialysis for new-onset ESRD during 2004-2013, who were propensity score matched to an equivalent number of non-dialysis subjects from the general population. The incidences of active TB in the ESRD and control cohorts were calculated for 2004-2013, and multivariable Cox proportional hazards model was used to evaluate the ESRD-related risk of active TB. Results: During 2004-2013, 59,584 patients received dialysis for newly diagnosed ESRD. In the dialysis and control cohorts, 457 (0.8%) and 125 (0.2%) cases of active TB were detected, respectively. Patients with ESRD were associated with a significantly higher risk of active TB compared to the controls (incidence rate ratio, 4.80). The ESRD cohort had an independently elevated risk of active TB (adjusted hazard ratio, 4.39; 95% confidence interval, 3.60-5.37). Conclusion: We found that patients receiving dialysis for ESRD had an elevated risk of active TB. These results highlight the need for detailed and well-organised guidelines for active TB screening among patients with ESRD.

Due to rapid development of high speed wire/wireless internet technologies, at the current age, it cares into being one phenomenon that the internet business is able to work on anyplace and anytime. In this environment, a technology of mobile agent provides very useful mechanism for personal handheld devices because of supporting migration as autonomously executable software object Instead of users. Therefore, this paper focuses on Implementing a mobile agent platform for personal handheld devices, which supports mobile agents in wire/wireless internet environment. To do this, we construct the system with modified JAMAS, based on Java, in our previous research. Based on our proposed system, we implement the browsing application in personal handheld devices to access the MIB(Management Information Base) on SNMP(Simple Network Management Protocol), which supervises network environment on wire/wireless internet. This proposed application system is easily to access the MIB managed by SNMP agent. then provides network map viewer and updates the MIB through the browser to network administrator. As a result, we can support application area of mobile agents such as hare network management. M-Commerce, integration of remote database systems, active message and active network with personal handheld devices.

The purpose of this study was to examine the appearance management motives and body image perception according to males' appearance management behavior. A set of questionnaire was administered to 398 male consumers. Data were analyzed by utilizing frequency, factor analysis, ANONA, cluster analysis, and crosstabs. Factor analysis of body image perception extracted four factors such as appearance concern, appearance satisfaction, exercise ability, and weight control. Four groups of the appearance management behavior were classified into such as health oriented, active figure management, indifference to personal appearance, and fashion/skin care by cluster analysis. All groups pursued sociality in appearance management motives. The active figure management group showed highest concern about in all the appearance management motives and body image perception.

Random Early Detection (RED) [1] is an active queue management scheme which has been deployed extensively to reduce packet loss during congestion. Although RED can improve loss rates, its performance depends severely on the tuning of its operating parameters. The idea of adaptively varying RED parameters to suit the network conditions has been investigated in [2], where the maximum packet dropping probability $max_p$ has been varied. This paper focuses on adaptively varying the queue weight $\omega_q$ in conjunction with $max_p$ to improve the performance. We propose two algorithms viz., $\omega_q$-thresh and $\omega_q$-ewma to adaptively vary $\omega_q$. The performance is measured in terms of the packet loss percentage, link utilization and stability of the instantaneous queue length. We demonstrate that varying $\omega_q$ and $max_p$ together results in an overall improvement in loss percentage and queue stability, while maintaining the same link utilization. We also show that $max_p$ has a greater influence on loss percentage and queue stability as compared to $\omega_q$, and that varying $\omega_q$ has a positive influence on link utilization.
