본 연구의 목적은 예비교사를 대상으로 하여 측정 자료의 불확실도 개념을 조사하는 것이다. 연구의 대상은 서울시내 소재한 대학의 예비교사 27명이었다. 예비교사들에게 개방적인 탐구과제를 수행하게 하고 이것을 관찰 분석하는 방법을 사용하였다. 예비교사들의 개념을 조사하기 위해 2차례의 질문지를 제시하였으며, 일부에 대해서는 면담을 실시하였다. 응답한 자료를 분석하여 불확실도의 개념요소인 대표값의 표현, 정밀과 정확, 오차의 분석, 불확실도의 전파 등으로 나누어 예비교사들의 개념을 정리하였다. 연구결과에 의하면 예비교사들은 대표값의 표현에서 과학자들의 개념과 다른 개념을 가지고 있었으며, 정밀과 정확을 혼돈하여 사용하고 정밀한 실험을 실시하는데 소홀하였다. 또한 오차를 나열할 뿐 그 원인이나 실험에 영향을 미치는 정도를 분석하는 경우는 거의 없었다. 이러한 연구결과는 예비교사와 학생들이 올바른 개념을 가지게 하기 위한 교육과정이나 교수 학습 자료 개발에 활용될 수 있을 것이다.

IMO introduced e-Navigation concept to improve the efficiency of ship operation, port operation, and ship navigation technology. IMO proposed sixteen MSPs (Maritime Service Portfolio) applicable to the ships and onshore in case of e-Navigation implementation. In order to meet the demands of the international society, the system implementation work for the Korean e-Navigation has been specified. The Korean e-Navigation system has five service categories: the S2 service category, which is a ship anomaly monitoring service, is a service that classifies emergency levels according to the degree of abnormal condition when a ship has an abnormality in ship operation, and provides guidance for emergency situations. The navigation safety module is a sub-module of the S2 service that determines the emergency level in case of navigation equipment malfunctioning, engine or steering gear failure during navigation. It provides emergency response guidance based on emergency level to the abnormal ship. If an abnormal condition occurs during the ship operation, first, the ship shall determine the emergency level, according to the degree of abnormality of the ship. Second, an emergency response guidance is generated based on the determined emergency level, and the guidance is transmitted to the ship, which helps the navigators prevent accidents and not to spread. In this study, the operational concept for the implementation of the Korean e-Navigation system is designed and the concept is focused on the navigation safety module of S2 service.

The purpose of this study is to examine the effects of background knowledge on problem solving. To achieve this aim, I proposed the model which shows problem solving process centering around background knowledge, conducted the lessons concerning the concept 'weightlessness' on pre-service elementary teachers, and then classified the pre-service elementary teachers into several groups by the difference of the results presented in the process of solving the problems on weightlessness. And I examined qualitatively the effects of background knowledge on problem solving through the interview with 11 volunteers. On the cause of the failing the problem solving, the failure of acquiring or activating the background knowledge related to the learning concept was most frequently, secondly the use of the background knowledge unrelated to the learning concept, and thirdly the failure of understanding the teaming concept. To acquire or activate the background knowledge related to the teaming concept was more difficult than to understand the new teaming concept, and the cases that use the background knowledge unrelated to the learning concept failed to solve problem. The result of interview, all interviewee understood the learning concept correctly, but all of them who fail to acquire or activate the background knowledge related to the learning concept, or use the background knowledge unrelated to the learning concept, could not solve the problem.

본 연구의 목적은 서비스 제공자(개발자)와 서비스 수혜자(고객)집단 간에 느끼는 디자인 컨셉 가치에 대한 비교연구로서 양압기(CPAP)를 중심으로 진행된 IoT기반 U-헬스케어 및 사용자 환경기반 서비스모델을 제시하여 사례연구로 진행하였다. 더블다이아몬드(Double Diamond)연구방법을 활용하여 울산에 소재한 U병원 이비인후과와 공동으로 사례 연구를 진행하였으며, 수면 무호흡 수면 환자들을 대상으로 진단부터 구매 후 사용까지 다양한 의미 있는 경험을 발췌하고 고객 유형별 차이점을 분류 하였다. 최종적으로 제시한 13개의 서비스 시나리오 모델을 대상으로 고객은 카노(Kano)만족도와 잠재적 고객만족 개선 지수(PCSI)평가를 진행하였고 개발에 참여한 서비스제공자 집단을 대상으로 스코어모델(+-)평가와 컨셉포지션(Concept Position)평가를 진행하였다. 본 연구를 통하여 도출한 결과는 총 12가지 문항에서 7가지 문항은 수혜자와 공급자 사이에서의 가치적 견해의 일치가 나타났으며 이는 사용자 환경기반 서비스모델 속성 이었으며, 반대로 가치적 견해가 상의한 결과인 5가지 문항은 IoT기반 U-헬스케어 서비스 모델 속성에 포함 되어 있었다는 것을 알 수 있었다.

The concept of revenue management have been used mainly in the service-industries like hotel and air transportation which handles perishable asset. Recently however, it is being increasingly applied to many other areas including travel, railway and medicine. This paper tries to introduce the concept into the internet business. Revenue management used in the service industry is a good system for the management of perishable asset. Internet business can be classified as various industries according to the characteristics of the individual companies. Contents providers and internet service providers are very similar to service industry, and revenue management system is suitable to them. This paper develops the ways to apply the revenue management concept to ISP business.

비생산적 활동이며 제조의 보조 활동으로 인식되었던 서비스가 '서비스' 자체로 고객의 수요를 이끌어내는 동력이 되면서 서비스 활동의 저변이 확대되고 서비스가 빠르게 진화하고 있다. 서비스시스템을 이해하기 위해 서비스 개념의 변화를 살펴보는 것은 중요하다. 서비스 시스템 자체가 서비스 개념을 기반으로 한 순환적 성격을 띠고 있으므로, 서비스 개념의 진화에 따라 서비스 시스템이 어떻게 변화하고 있는지를 살펴봄으로써 서비스를 '어떻게' 가치 있게 활용할 수 있는지 연구할 수 있기 때문이다. 관계를 구성하고 활용하는 능력은 서비스경제시대에 경영자에게 더욱 중요한 핵심 요인으로 꼽히고 있으나, 여전히 기업 경영자들의 관심은 내부적 역량에 초점이 맞추어져 있고, 외부자원(고객의 지식과 역량 등) 활용에 익숙하지 않은 실정이다. 이에 본 연구에서는 서비스 유형별 사례연구를 통해 서비스 관계 속에서 상호 작용하는 서비스 공급자-수요자들의 활동을 분석하고, 무형적 가치와 장기적 효과(Outcome)를 강조하는 신 서비스시스템모델을 구축하였다. 본 연구는 오늘날의 서비스경제시대에 맞는 고객의 역할을 재조명하고, 기업의 경영 성과를 위해 신 서비스 모델이 적극 활용될 수 있는 가치가 있다.

In this paper, we discuss about the implementation of CITIS(Contractor Integrated Technical Information Service) which is information infrastructure for CALS. CALS concept is introduced by DoD(Department of Defense, US) to exchange technical data of product's life cycle electronically. This CALS concept is accepted by commercial industrial area and considered as a part of global concept of Electronic Commerce. CITIS- a service defined by MIL-STD-974- is about to be implemented by commercial industrial society, too. But, until now there is a few sites implementing CITIS and especially in Korea. In this paper, we discuss characteristics of some CALS/CITIS implementation and solutions, and introduce ETRI-CITIS.

In this study, we conducted preliminary survey, diagnostic test and in-depth interview in order to study Korean pre-service chemistry teachers' understanding on entropy and investigate how Korean pre-service chemistry teachers deal with the natural phenomenon which is related to entropy conceptions. Firstly, as a result of the preliminary survey, it was found that pre-service chemistry teachers strongly recognized entropy as the degree of disorder. Secondly, the diagnostic test showed pre-service chemistry teachers were mostly confused about whether the entropy of the universe increases during a spontaneous change, and they had a tendency to interpret the natural phenomenon related to entropy change as the change of disorder. Finally, during in-depth interview, after we explained entropy change in all diagnostic test questions with the concept of microstate, pre-service chemistry teachers revealed a better understanding about entropy. Through this research, pre-service chemistry teachers had an opportunity to reflect on their deficiencies of entropy conceptions, which will ultimately help students to approach the concept of entropy more correctly.

Under the competitive environment of shipping industry, the improvement of the quality of shipping service could be one of the most important factors to be considered in the recent shipping industry. However, there has been little study on the clear concept of the service quality in the shipping so far. The subject of this study is to define the concept of the service quality in the shipping by way of making investigation into the related precedent literatures studied. The quality of service is recognized in general as a degree of gap between the customer's expectation and the perception. Therefore the service quality of shipping could be measured by evaluating the gaps between shipper's expectation and performance of shipping service. If the determinants of the service quality in the shipping are proved, and the discrepancies of expectations and perception between the shipping company and the shipper could be clarified, such a result would be an useful help to establish marketing strategy.
