The growing demand for the real time traffic information is bringing about the category and number of traffic collection mechanism in the era of ITS. There are, however, two problems in making data into information using various traffic data. First, the information making process of making data into the representative information, for each traffic collection mechanism, for the specified analysis periods is required. Second, the integration process of fusing each representative information into "the information" for each link out of each source is also required. That is, both data reduction and/or data to information process and information fusion are required. This article is focusing on the development of information fusing algorithm based on voting technique, fuzzy regression, and, Bayesian pooling technique for estimating the dynamic link travel time of networks. The proposed algorithm has been validated using the field experiment data out of GPS probes and detectors over the roadways and the estimated link travel time from the algorithm is proved to be more useful than the mere arithmetic mean from each traffic source.

Shape memory alloys(SMAs) have revolutionized the material engineering sciences as they exhibit exclusive features i.e. shape memory effect(SME) and super-elasticity. SMAs are those alloys that when deform return to their predeformed shape upon heating, they also restore their original shape by removing the load. Research on properties of newly advent of several types of ferrous based shape memory alloys(Fe-SMAs), shows that they have immense potential to be the counterpart of Nitinol(NiTi-SMA). These Fe-SMAs have been used and found to be effective because of their low cost, high cold workability, good weldability & excellent characteristics comparing with Nitinol(high processing cost and low cold workability) SMAs. Some of the Fe-SMAs show super-elasticity. Fe-SMAs, especially Fe-Mn-Si alloys have an immense potential for civil engineering structures because of its unique properties e.g. two-way shape memory effect, super elasticity and shape memory effect as well as due to its low cost, high elastic stiffness and wide transformation hysteresis comparative to Nitinol. Further research is being conducted on SMAs to improve and impinge better attributes by improving the material compositions, quantifying the SMA phase transition temperature etc. In this research pre-existing Fe-SMAs are categorised and collected in a tabulated form. An analysis is performed that which category is mostly available. Last 50 years data of Fe-SMA publications and US Patents is collected to show its importance in terms of increasing research on such type of alloys to invent different compositions and applications. This data is analysed as per different year groups during last 50 years and it was analysed as per whether the keywords exist in title of an article or anywhere in the article. It was found that different keywords related to Fe-SMAs/categories of Fe-SMAs, almost don't exist in the title of articles. However, these keywords related to Fe-SMAs/categories of Fe-SMAs, exist inside the article but still there are not too many publications related to Fe-SMAs/categories of Fe-SMAs.

이 글의 목적은 전문직의 정체성, 이른바 프로페셔널리즘(전문직업주의, professionalism)을 심도 있게 규명함으로써 통합적 관점에서의 전문직윤리의 중요성을 살피는 것이다. 구체적으로는 프로페셔널리즘에서 전문직윤리로 이행하는 과정에서 규범적 필요성을 강조함으로써 우리 사회에 적실한 전문직윤리의 가능성을 살펴볼 것이다. 해당 전문직종사자 간의 피할 수 없는 생존경쟁이 격화되고 있는 현실에서, 이른바 전문직의 희소가치가 감소 추세에 있는 오늘의 상황에서 프로페셔널리즘과 전문직윤리는 어떤 의미를 지니는가? 직업적 영향력과 경제적 보상이 전문직의 권력(professional power)을 구성하는 가장 큰 요소라고 할 때, 그 권력이 뚜렷하게 약화되고 있는 지금의 상황은 과연 통상적인 윤리(ordinary Morality)의 수준을 넘어서는 전문직윤리의 가능성을 확보할 수 있는가? 이 글은 전문직윤리를 통합적으로 다루면서 이러한 질문에 대한 답변의 실마리를 찾아볼 것이다.

The article examines the impact differences between producing concrete and asphalt. Both materials are widely used in the construction industry. Construction activities account for a large portion of greenhouse gases. Therefore, it is important to consider the Life Cycle Analysis (LCA) to reduce environmental impacts. In this study, the material processes were inputted into an LCA program called SimaPro. The database used for the study was Ecoinvent as it is one of the major databases within SimaPro. The materials were compared against impacts per kg of material produced as the functional unit. Each process was created using the materials, energy and transportation required to produce the materials. Waste streams were also included in the process to determine the impacts after the product was done with its useful life. Using the ReCiPe method, an LCA was conducted. Midpoint and endpoint categories were examined for both the productions. The processes had similar results for the human health and ecosystems categories; however asphalt was marginally higher for both. Asphalt had exceeded concrete in the resource impact category by 100 mPt. The results indicate that concrete is the more sustainable building material. Determination of various impacts of the materials is important for material selection.

Background : Performance evaluation of medical care providers has become more important than before in Korea. Especially in university hospitals, job contents of medical staffs are so complicated that evaluation is not easily performed. In addition, in order that the feedback of evaluation be successful, acceptance of staffs to be evaluated is essential. This study is aimed at the development of items for evaluation and weighting of each item in one university hospital, and clustering departments by different weight given by medical staffs. Methods : Through resource group meeting. performance items were listed up by categories of education, research, medical services, and other activities in and out of the hospital. For each item, all the medical staffs were asked how important they thought, compared with publishing one original article. By factor analysis, the items in each category were grouped into a few subgroups. In turn, cluster analysis was done for the purpose of grouping departments by priority the medical staffs gave. Results and Conclusion : Among five major categories, medical staffs regard education, research, and medical services more important than other activities in and out of the hospital. Five categories consisted of two or three components. Departments in hospital were grouped into three. However, characteristics of each group was not clearly delineated. This result suggests that more comprehensive tool should be developed and applied in the process of performance evaluation in university hospitals.

새로우면서도 재미있는 스토리텔링의 아이디어를 개발하기 위해 많은 연구가 이루어지고 있다. 이 중에서 전 세계적으로 성공한 작품을 가장 많이 보유하고 있는 디즈니에 관한 연구가 끊임없이 제시되고 있다. 본 연구는 이처럼 디즈니의 스토리텔링을 살펴보고자 하는 목적에 기반을 두고, 캐릭터라는 특정한 관점에서 원전에 해당되는 "목란시"와 <뮬란>을 비교함으로서 캐릭터가 변용을 확인해보았다. 분석을 통해 나타난 특징을 살펴보면 "목란시"와는 달리 <뮬란>에서는 캐릭터의 활용이 적극적으로 나타나고 있음을 알 수 있었다. 첫째로 캐릭터의 창조적 추가와 삭제가 있었다. 삭제된 캐릭터는 적지만 창조된 캐릭터는 많은 숫자임을 확인할 수 있었다. 이러한 창조는 현실적 캐릭터의 창조, 비현실적 캐릭터의 창조, 그리고 현실적 존재지만 비현실적 성격의 캐릭터라는 세 가지 형태로 나타났다. 두 번째는 캐릭터의 성격의 변형이다. "목란시"와 비교해볼 때 이런 특징을 보여주는 캐릭터는 뮬란에만 제한되고 있다. 뮬란은 목란과는 달리 남성적 적극성과 여성적 순응성이라 는 이중적 측면이 있음을 확인할 수 있었다. 이러한 두 가지 특징을 통해 제시된 캐릭터는 서사 구조에서 필요에 따라 특정 부분에 등장하는 모습을 보여주었다. 세 번째는 창조된 캐릭터와 변형된 성격의 캐릭터를 통해 캐릭터간의 관계를 설정한 것을 알 수 있었다. 그리고 이러한 관계는 주어진 역할에 따라 혈연적 성격의 1차적 집단에 속하는 캐릭터와 사회조직성격의 2차적 집단에 속하는 캐릭터로 구분할 수 있었다. 이러한 서사 구조 내에서의 캐릭터의 변용은 디즈니가 스토리텔링을 개발하는 과정에서 원전에 비해 좀 더 탄력적인 서사 운영을 위해 사용되었던 것임을 간접적으로 확인할 수 있었다. 이와 같은 연구결과의 도출은 특정 작품 사례에 대한 집중분석을 통해서 스토리텔링 전략의 실질적 활용을 했다는 것에 의미가 있지만, 디즈니의 다른 작품을 통해서 유사한 결과가 나올 수 있는지를 좀 더 연구해볼 필요가 있다.
