The routers in an active network perform customized computations on the messages flowing through them, while the role of routers in the traditional packet network, such as the Internet, is to passively forward packets as fast as possible. In contrast to the Internet, the processing in active networks can be customized on a per user or per application basis. Active networks allow users to inject information into the network, where the information describes or controls a program to be executed for the users by the routers as well as the end hosts. So the network users can realize the active networks by "programming" the network behavior via the programming interface exposed to them. In this paper, we devise a network protocol model and present a verification technique for reasoning about the correctness of an active application defined using the model. The technique is developed in a platform- and language-independent way, and it is algorithmic and can be automated by computer program. We give an example dealing with network auction to illustrate the use of the model and the verification technique.

The efficiency of magnetic compass direction sensor and magnetic compass by the laboratory experiment for the apparatus of generating artificial magnetic force and the onboard experiment on the fishing boat of coastal pot at the outside of Pusan Namhang were investigated. The results showed that the bearing angle of magnetic compass direction sensor was coincided with that of magnetic compass. However, the performance of magnetic compasses was unsuitable under the ISO rule by the characteristic experiment of damping curve. Therefore, the use of autopilot system using magnetic compass direction sensor which is based on the magnetic compass needs the sufficient notice.

Purpose: The purpose of this study was to investigate influencing factors on self-care in the elderly with essential hypertension. Method: The research instruments included the Self-Care Scale, the Knowledge Scale Related to Hypertension, the Self-Efficacy Scale and the Family-Support Scale. Results: The self-care was significantly associated with knowledge (r=.510, p=.000), self-efficacy (r=.708, p=.000), and family support (r=.403, p=.000). The major factors that affected subjects' self-care were knowledge and self-efficacy which explained 58.7% of self-care. Conclusion: Hypertension knowledge and self-efficacy are important factors for nursing interventions in caring for elderly patients with hypertension. It is needed to develop nursing programs for elderly patients with hypertension and to provide nursing interventions to improve knowledge and self-efficacy and, thereby, improving the self-care of elderly patients with hypertension.

The purpose of this study is to examine the service quality satisfaction in the franchisor-franchisee relation. For the result of this study, we studied the franchisees' answers to the questionnaires about franchisors' service quality. Through this study, we showed the basic data about the selective criteria of the franchisors' service quality. Based on this study, it can be concluded that there are differences in their service quality. The most effective factors of the franchisor's service quality are personnel service(0.510) and menu service(0.390). The finding is $R^2$ -0.489. Therefore, franchisor should pay attention to competent labor service and new menu development. Each factor affects satisfaction with franchisee's service quality, but only convenience and location are not affected.

Purpose: This study was to identify nursing interventive strategies centering around the meaning structure of elderly women self-esteem. Method: This study is based on a phenomenological approach. The participants were 6 women over the age of 65 selected in Mullae Senior Club or Yeongdeungpo Senior Welfare Center. The data was collected by in-depth and open- ended interviews from May to September, 2001. The analysis of the data was used the phenomenological analytic method suggested by Giorgi(1970). Result: Two essential themes in the selfesteem of relationships the elderly women emerged: (1) Self-identification through human relations: (2) The ability for self-control. Conclusion: There is a variety of programs and social meetings to confirm self and support systems, whether on the governmental level or the personal level, to help the ability for self-control should be expected to live a more qualitative life and successful aging for elderly women. In addition, this study will offer a better understanding of elderly women within the social and cultural context of South Korea.

A Direct injection -mixing total -flow -control sprayer was developed and evaluated . The system provided precise application rates and minimized operator exposure to chemicals as well as providing a possibility for recycling container so f unused chemicals that can causes environmental contamination. Chemicals were metered and injected proportionally to the diluent flow rate to provide constant concentrations. The main diluent flow was varied in response to changes in travel speed. Experimental variables of the sprayer were the control interval, the sensitivity of flow regulating valve, the tolerance of control object and the sensitivity of the injection pump system. The optimal performance of the flow control system was with an average response time of 8.5 sec at an absolute steady state of error of 0.067 L/min (0.8% of flow rate). The average response time of the injection rate was -0.53 sec and the coefficient of variation (CV) of concentration was 3.2%.

In this paper, variable characteristic ratio algorithm based on oscillometric method is proposed to enhance the accuracy of blood pressure measurement. We combined the slope-based approach and fuzzy inference technique to change the characteristic ratios of height-based method. The proposed algorithm was assessed on 255 measurements from 85 subjects and compared with the conventional height-based algorithm. The testing results showed that the developed algorithm achieved an overall grade A for both systolic and diastolic blood pressures according to the BHS protocol. And, mean standard deviation between the observers and the developed algorithm were 5.71mmHg and 6.29mmHg for systolic and diastolic pressures respectively, which also fulfilled the AAMI criteria. In conclusion, this algorithm was successfully developed and recommended for further clinical trials with the wider adult population.

Mardia (Biometrika, 57, 519-530, 1970) defined measures of multivariate skewness and kurtosis. Based on these measures, omnibus test statistics of multivariate normality are proposed using normalizing transformations. The transformations we consider are normal approximation and a Wilson-Hilferty transformation. The normalizing transformation proposed by Enomoto et al. (Communications in Statistics-Simulation and Computation, 49, 684-698, 2019) for the Mardia's kurtosis is also considered. A comparison of power is conducted by a simulation study. As a result, sum of squares of the normal approximation to the Mardia's skewness and the Enomoto's normalizing transformation to the Mardia's kurtosis seems to have relatively good power over the alternatives that are considered.

In this study, the ausformed martensite and marformed martensite obtained from austenite with various deformation degrees in Fe-31% Ni-0.2%C alloy were transformed to revesed austenite at $510^{\circ}C$ by cyclic reverse martensite transformation. The effect of prior deformation, the rapid heating rate of reversion and number of cyclic transformation on the microstructure, mechanical properties of reversed austenite were investigated. The reverse austenite transformation is accomplised by the mechanism of shear type transformation. The structure of reversed austenite formed from ausformed martensite and marformed martensite with high deformation degrees is a fine structure of nearly equiaed grain containg a high density of dislocation tangles and was largely affected by the prior deformation applied before reversal transformation. The strength of reversed austenite is more increased with of cyclic transformation especially it is strength at the first cyclic transformation. The yield stress of revesed austenite of ausformed martensite is lower than that of marformed martensite.
