  • In this paper, we have implemented UPnP Devices which emulate a Control Point, a Light Controller, and a Digital TV. The Control Point has been developed on Linux host system by using C language. The UPnP Devices emulating the Digital TV and Light Controller are running on embedded linux developer board. For the development of UPnP Devices, UPnP SDK API Vl.04 made by Intel Co. Ltd. has been ported on Assabet Linux Reference board to implement the UPnP protocol. After we analyze and design some services of Digital TV device, we have applied UPnP Device program to those devices. UPnP SDK vl .04 consists of APIs which support HTTP, SSDP, SOAP, GENA and XML DOM Level-1 that are cores of UPnP protocol. The C program written for the UPnP Control Point has been compiled and executed on Linux-based PC. The embedded system running on Embedded Linux OS has been connected all together through Ethernet which allows IP-based communications. Under this environment, the UPnP programs are being executed on each device. Control Point, when in operational mode, discovers UPnP Devices on the network and displays the device list on the consol. By selecting one of the functionalities of the device services that are displayed on the Control Point, the controllability has been accomplished. The experiment that we performed in this thesis have revealed that the Control Point and UPnP Devices have supported the protocols including SSDP, SOAP, GENA, and DHCP.

  • The control of electrical appliances residing in the home network can be accomplished via Internet with the UPnP expansion without modifying an existing UPnP. In this paper, we propose the Internet Gateway that consists of an UPnP IGD(Internet Gateway Device) DCP(Device Control Protocol) and an UPnP Bridge as a system to control electrical appliances of home network. UPnP IGD DCP is to enable the configurable initiation and sharing of Internet connections as well as assuring advanced connection-management features and management of host configuration service. It also supports transparent Internet access by non-UPnP-certified devices. UPnP Bridge searches for local home network devices by sending control messages, while control point of UPnP Bridge looks up devices of interest on the Internet, subsequently furnishing the inter-networking controlling among devices which belong to different home network systems. With our approach, devices on one home network can control home electrical appliances on the other home network via Internet through IGD DCP with control commands of UPnP.

  • Middleware enables different networking devices and protocols to inter-operate in ubiquitous home network environments. The UPnP(Universal Plug and Play) middleware, which runs on a PC and is based on the IPv4 protocol, has attracted much interest in the field of home network research since it has versatility. The UPnP, however, cannot be easily accessed via the public Internet since the UPnP devices that provide services and the Control Points that control the devices are configured with non-routable local private or Auto IP networks. The critical question is how to access UPnP network via the public Internet. The purpose of this study is to deal with the non-routability problem in local private and Auto IP networks by improving the conventional Control Point used in UPnP middleware-based home networks. For this purpose, this paper proposes an improved Control Point for accessing and controlling the home network from remote sites via the public Internet, by adding a web server to the conventional Control Point. The improved Control Point is implemented in an embedded GNU/Linux system running on an ARM9 platform.

  • In this paper we calculate the subgroup size necessary for detecting the change of percent defective with several detection probabilities for orginal population fraction nonconforming p, changed population fraction nonconforming $p^*$, and the ratio k=$p^*$/p in the usage of p control charts. From our calculation we can know the error level of normal a, pp.oximation in detection probability calculation and recommend the subgroup size with lower error levels of normal a, pp.oximation, and then we show the reasonable subgroup size necessary for p, $p^*$, k, and the detection probability of the change of fraction nonconforming in a process. The information that we here show in tables will be useful when p control chart users decide the subgroup size in the p control chart users decide the subgroup size in the p control chart.

  • BACKGROUND/OBJECTIVES: Numerous school-based weight control programs have been initiated for weight loss among adolescents. However, the relationship between these programs and inappropriate weight control efforts, dietary habits and behavior of students, have not been investigated sufficiently. This study was undertaken to investigate the association between body mass index (BMI) of adolescents, and their health status and inappropriate weight-control efforts. We further examined the relationship between attendance to school-based weight-control programs and attempting inappropriate weight-control efforts, dietary habits, and behavior. SUBJECTS/METHODS: A survey of 1,742 students was conducted in Korea. Logistic regression was used to assess differences in the health status (grouped by BMI and improper weight control) and dietary habits, based on attendance to the weight-control programs. RESULTS: Obese students were significantly more dissatisfied with physical, mental and spiritual health. Students who attended weight-control programs were likely to be underweight (P < 0.001), whereas those who did not attend weight-control programs were likely to attempt weight control improperly (P < 0.001). Students who participated in the program also had relatively healthy dietary habits (P < 0.001-0.027), and students who did not attend had comparatively unhealthy dietary habits (P < 0.001-0.008). Students who attended weight-control programs were likely to be underweight (P < 0.001) with relatively healthy dietary habits (P < 0.001-0.027), whereas students who did not attend the programs were likely to attempt weight control improperly (P < 0.001) and had comparatively unhealthy dietary habits (P < 0.001-0.008). CONCLUSIONS: Attending school-based weight-control programs was significantly associated with not attempting inappropriate weight-control efforts, as well as following healthy dietary habits. Our data indicates that offering school-based weight-control programs is valuable to student health, and is anticipated to reducing the public health burden.

And body weight changes were also monitored throughout whole experimental periods. The results were as follows : 1. Body weight of Control and Treatment group was significantly increased from 6 weeks after ovariectomy but after 2 days of drug administration, body weight of Treatment group were significantly (p<0.01 or 0.05) decreased compared with those of Control group. 2. Serum osteocalcin levels were significantly (p<0.01) increased in control groups compared with those of Sham group but significantly (p<0.01) decreased in the Treatment group. 3. Serum estradiol levels were significantly (p<0.01) decreased in control groups compared with those of Sham group but significantly (p<0.01) increased in the Treatment group. 4. Serum progesterone levels were significantly (p<0.01) decreased in control groups compared with those of Sham group but significantly (p<0.01) decreased in the Treatment groups. 5. Serum FSH levels were significantly (p<0.01) increased in control groups compared with those of Sham group but significantly (p<0.05) decreased in the Treatment group. 6. Serum Ca levels were significantly (p<0.01) decreased in control groups compared with those of Sham group but significantly (p<0.01) increased in the Treatment group. 7. Serum P levels were significantly (p<0.01) increased in control groups compared with those of Sham group and Treatment group. No significant was detected between Control group and Treatment group. According to these results, it is considered that the oral administration of Guirokyisun-Hwan have favorable effect on treatment and prevention of osteoporosis induced by ovariectomy in rats.

  • Purpose: This study was to identify the relations between stress and health locus of control in nursing college students. Methods: A total of 243 subjects aged between 17 and 27 were selected through convenient sampling. Data were collected with a self reported questionnaire from March 2 to 25, 2013. Collected data were analyzed with SPSS/PC Win 15.0. Results: Differences in stress and health locus of control according to general characteristics were as follows. Stress were significantly different according to gender (t=-2.51, p<.05), grade (F=5.40, p<.01), school record (F=5.72, p<.01), stress solving methods (F=2.62, p<.05). Internal health locus of control was significantly different according to gender (t=2.30, p<.05), grade (F=14.73, p<.001), religion (F=4.63, p<.01), school record (F=5.29, p<.01), economic state (F=5.50, p<.001) and smoking (F=4.17, p<.05). Chance health locus of control was significantly different according to sibling rank (F=2.86, p<.05). Except chance health locus of control, internal heath locus of control and dependence health locus of control have a negative correlation with stress. 15.6% of variance in stress was explained by dependence health locus of control, chance health locus of control, and grade. Conclusion: The findings of this study may be useful in understanding the stress expression of nursing college students and developing more specific programs on personality and self-control.
