This study aimed to establish an observation protocol for mathematical modeling as an alternative way to examine instructional alignment to the Common Core State Standards for Mathematics. The instructional alignment observation protocol (IAOP) for mathematical modeling was established through careful reviews on the fidelity of implementation (FOI) framework and prior studies on mathematical modeling. I shared the initial version of the IAOP including 15 items across the structural and instructional critical components as the FOI framework suggested. Thus, the IAOP covers what teachers should do and know for practices of mathematical modeling in classrooms and what teachers and students are expected to do. Based on the findings in this study, validity and reliability of the IAOP should be evaluated in follow-up studies.

BICC protocol is a relay protocol adaptable to ATM and IP based core networks compared to ISUP protocol to TDM networks. Using BICC protocol, multi-rate bearer traffic such as voice and video can flow in the relay core networks. BICC protocol is standardized as WCDMA circuit switching networks in 3GPP Release 4. Thus KTF is now operating core networks using BICC protocol. In this paper, we describe the background and characteristics of BICC protocol. We also provide the status of KTF WCDMA core networks using BICC. To show the efficiency of BICC protocol an analytical simulation is given in which the results can be expected by intuitive observation.

본 연구는 좋은 과학수업에 대한 과학교사의 인식을 알아보기 위해 수행되었다. 이를 위해 과학수업을 관찰하고 개선하기 위한 목적으로 개발된 KTOP(Korean Teaching Observation Protocol)을 이용하여, 1차로 KTOP의 각 항목들이 좋은 과학수업을 위해 중요하다고 생각하는지, 어느 정도로 실행하고 있는지, 그리고 어느 정도로 실행하기 어렵다고 생각하는지를 조사하였고, 2차로 실행하기 어려운 KTOP 항목들에 대한 이유와 해결 방안은 무엇이라고 생각하는지를 조사하였다. 1차로 63명과 2차로 35명의 과학교사로부터 얻은 응답은 응답의 특성에 따라 유형별로 분류하고, 분류한 내용을 요약하여 그 특징을 논의하였다. 그 결과, 과학교사들은 1개의 항목을 제외한 KTOP의 모든 항목들이 좋은 과학수업을 위해 중요하다고 응답하였으나, 실행하기 어려운 경우에는 실행정도가 낮은 것으로 나타났다. 중요하지만 실행하기 어려워 실행정도가 상대적으로 낮은 것으로 나타난 13개 KTOP 항목에 대해서는 그 이유를 학생과 교사에게 있는 것으로 많이(69%) 응답하였으나, 어려움에 대한 해결방안은 교사에게서 찾아보려는 응답(60%)이 가장 많았다. 이로부터 좋은 과학수업을 위해서는 외적인 환경보다는 교사들에 대한 이해와 지원, 역량 강화 등이 중요하다는 것을 알 수 있었다. 본 연구 결과가 과학수업에 대한 교사의 어려움을 구체적으로 이해하고, 어려움을 해결하기 위해 실제에 기반한 노력에 기여할 수 있기를 바란다.

본 연구에서는 KTOP (Korean Teaching Observation Protocol)을 과학과 교육실습에 적용하여 예비교사들의 수업 개선을 위한 과정을 돕고자 하였다. 4명의 예비교사와 지도교사가 KTOP을 이용하여 수업을 관찰, 분석하고, 협의 과정을 통해 다음 수업을 개선하는 과정으로 교육실습을 실시하였다. 그 결과, 예비교사들은 KTOP에 의한 수업분석 결과에 기초하여 협의 활동을 하여 KTOP이 예비교사들의 수업 개선에 실제적인 안내역할을 한다는 것을 알 수 있었다. 또 KTOP을 이용한 협의 활동이 다음 수업의 개선에도 도움을 주는 것을 볼 수 있었다. 그러나 보다 더 효과적인 수업 개선을 위해서는 더 많은 반복적인 적용이 필요하다는 것도 추론할 수 있었다. 교육실습과정에 대한 관찰과 면담, 설문을 통해 KTOP이 보다 더 효율적으로 활용되기 위해, 교사는 KTOP 활용에 대한 확신을 갖고 학생 중심의 수업이 되기 위해 노력하는 것이 필요하고, KTOP의 항목수를 줄이고, KTOP의 양식을 좀 더 편리하게 수정할 필요가 있음을 알 수 있었다. 그리고 학생들에게 학습이란 자기 주도적으로 수행되어야 한다는 인식을 갖도록 노력할 필요가 있다는 것도 추론할 수 있었다.

Wireless sensor network(WSN) is being used in various fields such as reconnaissance, echelon scale identification, weather observation, etc. using small sensors in an environment without a network infrastructure environment. In addition, WSN uses limited battery power, so study on routing protocols to extend the lifetime of the network is important. PEGASIS, a hierarchical routing protocol, accounts for the majority of energy-efficient routing protocol studies and is well known as a representative protocol. In this study, based on PEGASIS, we propose a protocol that constructs multiple chains rather than one chain using the AoA of nodes. The proposed protocol has the advantage of reducing the transmission distance of nodes and eliminating unnecessary transmissions, thereby increasing energy efficiency compared to the existing protocols.

Several ISDN (Integrated Services Digital Network) protocols have implemented at ETRI (Electronics and Telecommunications Research Institute) in an experimental network so that functional characteristics of the protocols under test could be certified against their protocol specifications with the help of the ETRI protocol test facilities. This paper describes ETRI protocol test architecture and its application to testing the NSP (Network Service Part) protocols : MTP (Message Transfer Part) level 3 and SCCP (Signalling Connection Control Part) of the CCITT CCS (Common Channel Signalling ) system No. 7 The test architecture presented here allows tests for two different protocol classes : peer-to-peer and multipeer protocolos. Some extensions are made to the conventional test architectures, namely the test coordination, test result transfer and network state observation method.

Purpose: The purpose of this study was to develop an evidence-based dysphagia nursing care protocol for nursing home (NH) residents in Korea. Methods: The protocol was developed based on international guidelines and literatures. After testing content validity by experts, the protocol was applied to the intervention group (n=35) for 4 weeks at one NH in December, 2011, whereas the control group (n=34) received routine care. Results: The protocol was composed of one-page algorithm and detailed guidelines. Algorithm pathway was organized in 3 parts, including screening dysphagia risk, grouping by dysphagia risk level, and assigning nursing care into each group. The nursing care included positioning, oral care, meal time care, diet modification, providing exercise and maneuver, and checking dysphagia signs and symptoms. The experts verified the content validity. Protocol was revised to fit NH practice after the participant observation. Clinical validity was established upon evaluating usefulness, appropriateness, and convenience of the protocol by NH nurses. Dysphagia risk of the intervention group was significantly decreased. Conclusion: Developed protocol will improve the quality of dysphagia care in nursing homes as it can serve as a consistent and integrated standard for nursing care of residents with dysphagia.

In this paper, we propose a method for transmitting SMS(Short Message Service) for VoIP(Voice over IP) service supporting multi-protocol. The multi-protocol VoIP under consideration are generally composed of H.323, SIP and MGCP and Most ITSPs(Internet Telephony Service Provider) provide VoIP service with H.323 and SIP now. SMS is killer application in mobile telecom service and many people of various field use that service. For example, user can send many SMS messages and substitute e-mail. Also SMS can be provided with various internet application. Ahn, legacy phone of KT, can use SMS. Therefore VoIP phone also can be required with the same requirement. With the multi-protocol VoIP we will propose several methods sending efficiently SMS. To show the validity of the proposed method some examples are given in which the results can be expected by intuitive observation.
