In the recent years, as smart phones popularized, the number of people who use IMS (instant messaging service) and SNS (social network service) rapidly has increased as the usage of SMS (short message service) relatively decreased. That is why this thesis suggests a contact control service based on Android. It contains an inducing function that calls acquaintances, which were given a score based on the level of familiarity from saved contacts and call logs. And it provides an overall ranking of call log in order to grasp frequently called people. This developed system was tested on Samsung Galaxy S2 and LG Optimus LTE / Android 2.2 which were the main smart phone models.

For stable and sustainable energy supply, distributed generator (DG) has become an essential and indispensable element from environmental and energy security perspectives. However, installation of DG in distribution systems may cause negative affects on feeders because power outputs of DG could be changed irregularly. One of major negative affects is variation in voltage profile. In general, voltage regulation devices such as under load tap changer (ULTC) at distribution substation and step voltage regulator (SVR) along feeder in distribution system are used to maintain customers' receiving voltage within a predetermined range. These regulators are controlled by line drop compensation (LDC) method which calls for two parameters; the equivalent impedance and the load center voltage. Therefore, consideration of DG outputs in the LDC parameter design procedure may give large impact on the installable DG capacity. This paper proposes a method that estimates maximum Installable DG capacity considering LDC parameters of ULTC and SVR. The proposed algorithm is tested with model network.

Times are changing in Italian healthcare and Traditional and Non Conventional Medicine has become increasingly relevant to medical practice. With this comes an increasing need for guidelines. As the use of Traditional and Non Conventional Medicine has increased in Italy, so has the need for high standards in education in this field (outside of biomedicine and the dominant health system) among medical students, medical doctors and medical educators. The rise of Traditional and Non Conventional Medicine is so relevant for medical practice and health care in Italy; the time calls for a change. The article describes this new setting in regards to education in Acupuncture within the field of Traditional Chinese Medicine in Italy's oldest private school.

When the load in a multi-cell orthogonal frequency division multiple access (OFDMA) system is allowed to excessively increase in face of frequent handover, the cell area becomes smaller than the designed size, and thus continuity of quality of service (QoS) for handover requests cannot be guaranteed. To efficiently support the mobility of a mobile terminal (MT), we should adaptively cope with the resource demand of handover calls. This paper proposes a twofold resource-reservation scheme for OFDMA systems to guarantee continuity of QoS for various mobile multimedia services during MT handover from lightly to heavily loaded cells. Our twofold scheme attempts to guarantee service continuity for handover and to maximize resource allocation efficiency. We performed a simulation to evaluate our scheme in terms of outage probability, handover failure rate, total throughput, and blocking rate.

Purpose: To evaluate the emergency medical protocols and need assessment through the case report Method: The study investigated the emergency call system through the 1339 emergency patients information center in 1997. Results: The emergency calls tend to follow general trends of the type of cases : abdominal pain (13.5%), unconsciousness(12.0%), traffic accidents (7.4%), bleeding (6.6%), respiration difficulty (5.9%). This was all collected through emergency medical protocols injury and poisoning (22.3%), symptom (51.6%), others (26.1%). Conclusion: The results suggest that a specific training program for emergency medical dispatchers should be established, and emergency medical dispatcher managers must review the cases on the basis of emergency medical protocols every year. Emergency medical services, furthermore, will continue to raise the standard for emergency medical dispatching.

Curriculum reform has been a significant emphasis for most of countries all over the world for the past few years. It was the first time for Taiwan to develop a new Science and Life Technology curriculum Standards (SaLTS) for grades 1 through 9 compulsory educations. The SaLTS features integrated science content with the aim at motivating students to learn science and encouraging students to apply science to their everyday life, which is practically well aligned with the philosophical essence and foundations of Earth Systems Education (ESE). This paper calls attention to the importance of the inclusion of ESE into the forthcoming science curricula of Taiwan and worldwide and provides some exemplary ESE-inspired curriculum and instructional modules that have been successfully implemented in the secondary schools of Taiwan. Hopefully, this paper can shed some lights on the future development of the ESE-based science curricula, instructional modules, and teacher preparation programs.

One of the major sources of error in precise GPS positioning since the turn-off the Selective Availability(SA) is the ionospheric propagation delay. For the last decades, a lot of the ionospheric researches based on a GPS network have been implemented throughout the world. Especially researches of the ionospheric modeling for Wide Area Argumentation System(WAAS) have been undertaken and published. In mid-latitude regions, typical spatial and temporal variations in ionospheric models delay tend to minimal. The developed ionospheric model calls for a 1.25 degree grid at latitudes and a 2.5 degree grid at longitudes. The precise grid TEC estimated by the inversion technique is also compared with global ionosphere maps(GIMs) which have been provided by several analysis centers(ACs). The results of initial investigations into the suitability of the proposed ionospheric modeling scheme in north-east Asia are presented.

본 논문에서는 오버플로우에 관한 연구에서 흔히 나타나는 이단계 대기모형을 연구하였다. 첫번째 단계는 여러개의 큐(queue)로 이루어져 있고, 이 큐들의 수용능력을 넘어서는 순간에 두번째 단계로 오버플로우가 발생한다. 두번째 단계로의 입력과정을 두 개의 상태를 가지는 MMPP로 근사함으로써 손실확률에 대한 계산을 이끌어 내었다. 근사방법으로써, Heffes의 방법과 SAM procedure를 이용하였다.
