수도권으로 인구가 집중되면서 광역 통행의 비중이 증가하게 되었다. 이러한 상황에서 서울시는 광역 통행에서 승용차 통행량을 줄 이고 대중교통의 편리성을 강화하여 대중교통이 광역 통행 수요를 분담하도록 하는 동시에 도심 주요 지역의 고밀복합개발을 통해 효 율적으로 도시 인프라를 개발하고자 하는 목적으로 서울시 여러 곳에 광역복합환승센터를 설치하였다. 본 연구는 이러한 복합환승센 터가 잘 기능하는지 평가하고 추후 다른 환승센터를 계획할 때에도 활용 가능한 평가 지표를 개발하고자 하였다. 평가를 위한 지표는 교통 기능 평가 지표 4가지, 도시 기능 평가 지표 3가지로 총 7가지의 지표를 선정하였으며, 환승센터마다 하나 의 점수로 환산 가능하도록 이 지표들을 하나의 선형식으로 통합하였다. 스마트카드 데이터로 환승시간, 광역교통분담률을 계산하였으 며, 교통카드 빅데이터 시스템상의 데이터를 통해 혼잡도와 접근성 평가 데이터를 추출하였다. 또한, 주변 지역 활성화도 관련 지표들 은 서울 열린 데이터 광장에서 취득하였다. 선형식의 각 변수의 계수는 서울시립대학교 교통공학과 구성원들을 대상으로 AHP 설문을 실시하여 얻은 지표별 가중치를 이용하여 결정하였다. 그 결과 광역복합환승센터 평가에 가장 큰 영향을 미치는 요소는 환승시간과 혼잡도였으며, 가장 적은 영향을 미친 요소는 용적률 활용도였다. 또한 완성된 선형식으로 서울역과 청량리역 환승센터를 평가한 결과 종합적으로 서울역 0.801543점, 청량리역 0.742488점으로 서울역이 청량리역보다 광역복합환승센터로서의 기능을 더 잘 수행하고 있는 것을 확인할 수 있었다. 환승시간, 용적률 활용도 등 일부 지표가 청량리역에서 우세하였으나 혼잡도나 주변 지역 활성화 지표가 서울 역에서 더 좋은 평가를 받은 점이 원인일 것으로 분석되었다.

The purpose of this study is to investigate the influence of social factors on the use of honorific language by discourse completion test. Participants complete a short discourse by filling in their responses in conversations that may occur in families, schools, and workplaces where the social status and solidarity of the listener is predetermined. Honorific styles of sentence endings of their responses are analyzed by the generalized linear mixed model. The results show that social status and solidarity are statistically significant factors in the use of honorific styles, but their effects are dependent on the discourse situation. The ratio of using honorific styles gradually increases as the formality of situation increases (i.e., family < school < workplace). Interestingly, when the solidarity is low at the workplace, the ratio of using honorific styles is consistently high regardless of the social status of the listener. These results show that the use of Korean honorific styles is pragmatically changing according to the discourse situation.

Expression type for mixed-use of Dongba characters can be divided into dominant type and parallel type. Causes for mixed-use includes three points: 1. similar or compatible patterns are the precondition for mixed-use; 2. certain relation exists among semantics of words represented by characters, or characters belong to the same classification in terms of meaning or have correlative meanings; 3. outcome is obtained during self-adjustment transitional stage of internal character of writing system. There are three solutions to solve the problem of similar characters: 1. re-distribution of characters’ functions; 2. integration of characters; 3. reconstruction of expression which is embodied in two aspects, including ideographical and phonetic expression transited from ideographical expression to additional phonetic complement, and transition from ideographical expression to pure phonetic expression.

An advocate of the exclusive use of Hangul asks to an advocate of mixed use of Chinese characters. We don't have any problems in delivery of meaning by only using of Hangul, and don't get any educational effects by teaching Chinese characters, then why do we have to study Chinese characters mixed that are the remnants of Japanese colonial era, why do we increase studying burden and private education? On the other hand, an advocate of mixed use of Chinese characters ask to an advocate of the exclusive use of Hangul. We can't communicate clearly by only using of Hangul, and ㄴstudying Chinese characters strengthen thinking power, then why do we have to stop the mixed use of Chinese characters that is effective in education of students. There are big differences of opinion each other. How can we harmonize these two conflicting thoughts. In results, We have to stand not on the scene of a dispute but on the field of an education, and we have to watch and judge this problem as we think about my own child. Which is effective in understanding any vocaburary, and in improving Korean language ability? This question is the only one standard of choicing way to go. Learning and communicating capabilities, thinking and creating powers of students are the most important factors in judging way to go. Any other factors have to be excluded.

In recent years, the construction of high-rise buildings are promoted. According to these, there are many needs about new technologies to strengthen the building performance and high-strength steel is regarded as one of these for promoting building performance. In Korea, high-strength steels which stress are over 600MPa are on market and in aborad, super high-strength steels over 1000MPa are developing and they expected to promote the building performance. But there are still doubts about applying high-strength steel members because of size effect and worry of brittle fracture. In this reports, we propose results of performance and analysis tests for use with general steel. We propose the characteristic of high-strength steels first and next the results of performance test to show they satisfy the performance that designers expect. And last, we compare the results of test and analysis for acquire the alanysis reliability in non-linear analysis with high-strength steels.
