On the situation cooperating with business partners on the supply chain, systematic decision making process is a critical issue for them. The two major issues of purchasing strategy such as selecting vendors and managing them are important part of their overall business activities. This study mainly focus on the former issue of the vendor selection. Through the empirical study, analytical hierarchy process (AHP) method was applied to select vendors among supplier vendors based on four selection criteria such as the level of quality, product on management ability, delivery, and price. The results of study showed the main criteria of vender selection was the ability of quality management. The vender selected based on AHP and the current selection method was different, but implicitly projected the dilemma situation between quality and price which occurs in decision making process of real life.

본 연구의 목적은 자연수 뺄셈의 실생활 맥락 문제 상황에서 '큰 수'와 '작은 수'의 제시 순서와 관련한 교수학적 의사결정의 관례에 대한 개선 방안을 모색하는 것이다. 이를 위하여 수학 교과 전문성을 가지고 있는 초등교사 30명을 대상으로 자연수 뺄셈의 실생활 문제 상황에 등장하는 크고 작은 두 수의 제시 순서와 뺄셈 상황에 대한 교수학적 인식을 조사하였다. 설문 조사를 통해 수집한 자료는 뺄셈의 문제 상황 유형을 분석 기준으로 활용하여 양적, 질적 분석을 하였다. 연구 결과, 뺄셈에 대한 학생들의 사고의 폭을 넓힐 수 있도록 실제 상황의 크고 작은 두 수의 제시 순서를 유지하는 뺄셈의 실생활 맥락 문제 상황을 활용하여 지도할 필요가 있다. 그리고 다양한 실생활 기반의 뺄셈 문제해결 학습이 이루어질 수 있도록 '큰 수'를 먼저, '작은 수'를 나중에 생각해야 하는 문제 상황으로 변형시키는 관례적인 교수학적 조치에 대한 제고가 필요하다. 이를 위해서는 자연수 뺄셈 지도 시 '큰 수'를 먼저, '작은 수'를 나중에 생각해야 하는 뺄셈 문제 상황뿐만 아니라 실생활에서 종종 등장하는 '작은 수'를 먼저, '큰 수'를 나중에 생각하게 되는 뺄셈의 실생활 맥락 문제 상황 도입에 대한 필요성을 교사가 인식하고 이에 대한 교수학적 견해를 갖출 수 있도록 수업 반성 및 연찬의 기회를 제공해야 할 것이다.

전통적 개발방법론에서는 요구분석단계에서 요구사항들이 한번 정리되면 이들은 개발이 완료될 때까지 변경이 없을 것으로 간주한다. 그러나 현실적으로는 개발기간 중 목표 시스템의 구체화, 정보기술의 발전, 적용환경의 변화 등으로 인하여 요구사항은 끊임없이 변화하게 된다. 본 논문에서는 개발방법론에서 미흡한 요구사항 관리를 개선하기 위하여 요구사항의 관리를 전체 개발 생명주기로 확대하고, 지속적으로 발생하는 요구사항의 변경을 효율적으로 관리할 수 있는 요구사항의 명세화 방안을 제시한다.

Purpose: The purpose of this study was to understand the meaning of the driving force of life experienced by the elderly and the realistic structure of their experience. Methods: The research question was "What is the essential meaning of the driving force experienced by the elderly?". Data were collected from individual in-depth interviews between March, 2017 and May, 2017 and analyzed using Van Manen's hermeneutic phenomenological methodology to identify the essential themes of their experience. Results: Through the analysis process, 22 themes and 14 essential themes were derived. The 14 essential themes of the driving force of the life of elderly were as follows: 'Memories from the past', 'Poverty to escape', 'Hand down family's heritage', 'A body bound by marriage', 'A body necessary for old age', 'A dignified body even if they grow older', 'A body that does not want to fall', 'A fruit of my life', 'Mature real love', 'Unchanging fraternity', 'Extended family', 'An old friend with whom share my heart', 'Satisfied with the situation', and 'Expanding the breadth of life'. Conclusion: Nursing programs that assess the driving force of life supporting the elderly and supports the driving force of such a life should be developed.

우리나라는 고유어 수사와 한자어 수사로 구성된 이중 수사 체계를 사용하고 있다. 이러한 이중 수사 체계는 실생활에서 관습적으로 특정 방식이 선택되거나, 두 가지 방식이 혼용되기도 하고, 불규칙하게 변형되기에 수사 학습지도 과정에서 학생과 교사 양측의 부담이 가중된다. 이에 본 연구는 이중 수사 체계로 인한 학습 지도 난점 개선의 필요성을 인지하였다. 이를 위하여 수사 체계 방식이 선택되는 맥락과 다양한 변형 사례, 현행 교육과정과 교과서의 관련 지도 내용을 분석·정리하였다. 분석 결과, 수사를 사용하는 실제 상황에 따라 나타나는 수사 체계 방식의 선택 및 변형의 특징이 존재하였으나 그러한 특징의 기준이 모호하고 교육과정 및 교과서 내 구체적인 지도 지침 또한 부재하였다. 이 경우 현장 교사의 역할이 더욱 중시되기 때문에 교사는 이중 수사 체계 관련 실제 상황의 세부 특징을 인지하고 학생에게는 이중 수사 체계 사용의 다양한 측면에 대한 경험과 연습을 통하여 이해하게 만듦으로써 수사 체계 교수·학습 개선을 위한 방향을 논의하였다.

In this paper, authors will develop the quick and precise remote controller of automatic fire detection equipment (P-type one-class receiver) based on information communication technology (IT). The remote controller detects the fire and disaster in the building automatically and quickly and then activates the facilities to extinguish the fire and disaster, monitoring such situation in a real time through wire-wireless communication network. The proposed remote controller is applied a programmable logic device (PLD) micom. of one-chip type which is small size and lightweight and also has highly sensitive-precise reliabilities. The one-chip type PLD micom. analyzes digital signals from sensors, then activates fire extinguishing facilities for alarm and rapid suppression in a case of fire and disaster. The detected data is also transferred to a remote situation room through wire-wireless network of RS232c and bluetooth communication, and then the situation room sends an emergency alarm signal. The automatic fire detection equipment (AFDE) based on IT will minimize the life and wealth loss while prevents fire and disaster.

'Hanok(韓屋)' is the settlement that our ancestors completed for our lives through multiple verifications. Thus, there exists our nation's identity and a variety of tangible and intangible cultural elements are included in that settlement. Even though the dwelling planning of Hanok has been introduced by the modern trends of traditional style, it can not present the type of various space compositions according to the area and living characteristics and it shows a disparity in our real life through the introduction of the traditional Hanok's elements which are not fit into contemporary housing without filtration. To solve these problems, it must need to study on cases based on the present situation of the Hanok and analysis on characteristics. For the Hanok to meet the development of modern residence, there needs to study on many fields such as plan, complex, structure, material. Among them, this study intends to present the preliminary data for the improvement of Hanok's effectiveness by understanding and analyzing the current situation focusing on the natural transformation of Hanok which are currently building in Milyang Area. Also, as the second step of this study, this study attempts to analyze based on the present situation of New Hanok in Kyeongnam province by expanding the range.

Recently, mathematical modeling has been attractive in that it could be one of many efforts to improve students' thinking and problem solving in mathematics education. Mathematical modeling is a non-linear process that involves elements of both a treated-as-real world and a mathematics world and also requires the application of mathematics to unstructured problem situations in real-life situation. This study provides analysis of literature review about modeling perspectives, case studies about mathematical modeling, and textbooks from the United States and Korea with perspective which mathematical modeling could be potential and meaningful to students even in elementary school. Further, teaching method with mathematical modeling was investigated to see the possibility of application to elementary mathematics classroom.

Because the noise is the main cause for decreasing the performance at speech recognition, the place or environment is very important in speech recognition. To improve the speech recognition performance in the real situations where various extraneous noises are abundant, a novel combination of FIR and Wiener filters is proposed and experimented. The combination resulted in improved accuracy and reduced processing time, enabling fast analysis and response in emergency situations. Usually, there are many dangerous situations in our city life, so for the smarter city it is necessary to detect many types of sound in various environment. Therefore this paper is about how to detect many types of sound in real city, especially on CCTV. This paper is for implementing the smarter city by detecting many types of sounds and filtering one of the emergency sound in this sound stream. And then it can be possible to handle with the emergency or dangerous situation.
