We can monitor home from any remote location using our existing telephone line. We have already some technologies to perform these types of application such as: Bluetooth, IR. But these are used in a limited area which we can easily come over in our system. Our propose system has two sections one is Remote Section (RS) where the client will place the request and another is Local Section (LS) where the telephone line is connected with an Input Interfacing Circuit (IIC). Input Interfacing Circuit (IIC) receives the frequency and converts frequency to machine language. Output Interfacing Circuit (OIC) sends voice signal to the client as acknowledgement through modem then the client proceeds for the next steps. This system can be used in commercial or industrial purposes such as controlling computer from remote locations, home monitoring system instead of man or any kind of switching.

Purpose: Cancer patients experience a range of physical and psychological sequelae. Consistent nursing support should be provided along the cancer treatment path. This study aimed to i)examine the effects of a telephone counseling program after discharge on perceived health, psychological well-being, and satisfaction with nursing services, and ii)describe symptom distress and their coping methods. Method: The study was a quasi-experimental design with a non-equivalent pre-post test. The sample included 20 women with gynecologic cancer in the experimental group and the same in the control group from a university hospital in Seoul. The telephone intervention was given once from 5 to 7 days after the chemotherapy. The General Well-Being Schedule and Symptom Distress Scale were used. Result: An effect from telephone counseling was found only in the vitality subscale of psychological well-being. Other subscores, perceived health, or satisfaction with nursing services did not differ between the two groups. Pain, skin change, decreased appetite, and constipation were the major symptoms and a relatively few coping strategies were utilized. Conclusion: Protocol of telephone counseling led by a nurse needs to be further developed in regard to best timing, amount, and target effects for follow-up care of gynecologic cancer patients.

This study was designed to evaluate the effect of individualized diabetes nutrition education. The nutrition education program was open to all type 2 diabetes patients visiting the clinic center and finally 67 patients agreed to join the program. To compare with 67 education group subjects, 34 subjects were selected by medical record review. The education program consisted of one class session for 1-2 hours long in a small group of 4~5 patients. A meal planning using the food exchange system was provided according to the diet prescription and food habits of each subject. Measurements of clinical outcomes and dietary intakes were performed at baseline and 3 months after the education session. After 3 months, subjects in education group showed improvement in dietary behavior and food exchange knowledge. In education group, intakes of protein, calcium, phosphorus, vitamin $B_2$, and folate per 1,000 kcal/day were significantly increased and cholesterol intake was significantly decreased. They also showed significant reductions in body weight, body mass index (BMI), and fasting blood concentrations of glucose (FBS), HbA1c, total cholesterol, and triglyceride. However, no such improvements were observed in control group. To evaluate telephone consultation effect, after the nutrition education session, 34 subjects of the 67 education group received telephone follow-up consultation once a month for 3 months. The others (33 subjects) had no further contact after the nutrition education session. Subjects in the telephone follow-up group showed a decrease in BMI, FBS, and HbA1c. Moreover, the subjects who did not receive telephone follow-up also showed significant decreases in BMI and FBS. These results indicated that our individually planned education program for one session was effective in rectifying dietary behavior problems and improving food exchange knowledge, and quality of diet, leading to an improvement in the clinical outcomes. In conclusion, our individualized nutrition education was effective in adherence to diet recommendation and in improving glycemic control and lipid concentrations, while follow-up by telephone helped to encourage the adherence to diet prescription.

In this study, a simulation model is developed to analyze the effects of routing and scale-economy of transmission facilities on the traffic network topology and investment cost changes in a metropolitan telephone network. Computational experiments showed that the wide deployment of bifurcated routing in a dual-homing configuration reduces significantly the traffic network connectivity and the investment cost. Its enhanced version, when combined with the subscriber network cost model, can be used as a prototype cost proxy model for figuring out the access charges in a multi-operator environment.

In this paper, we describe various efficient optimization algorithms for obtaining an optimal customer allocation in the telephone call center. The main advantages of the proposed algorithms are simple, fast and very attractive for massive dataset. The proposed algorithms also provide comparable performance with the other more sophisticated linear programming methods. The proposed optimal allocation algorithms increase the customer contact, response rate and management product and optimize the performance of call centers. Simulation results are given to demonstrate the effectiveness of our algorithms.

In this paper, we review the conventional speaker verification algorithm and present the text-dependent speaker verification system for application over telephone lines and its result of experiments. We apply blind-segmentation algorithm which segments speech into sub-word unit without linguistic information to the speaker verification system for training speaker model effectively with limited enrollment data. And the World-mode] that is created from PBW DB for score normalization is used. The experiments are presented in implemented system using database, which were constructed to simulate field test, and are shown 3.3% EER.
