본 연구는 주 · 야간 상업가로만족도에 미치는 영향요인을 확인하기 위해 서울시 인사동길을 선정하였다. 조도차이에 따라 인사동길의 구간을 분류하고 구간별 주 · 야간 설문조사를 실시하였다. 위계적 회귀분석을 실시하여 주 · 야간별 상업가로에 영향을 미치는 요인을 확인하였다. 그 결과 첫째, 주간의 경우 구간 간 가로만족도차이가 없는 것으로 나타났으나 야간은 유의미한 차이가 나타났다. 둘째, 주간은 쾌적성의 영향력이 가장 높았으며, 건축물, 상업환경 순으로 분석되었다. 야간은 건축물, 가로, 연속성 순으로 영향력이 높게 나타나 경관적인 측면이 강해지는 것을 확인할 수 있었다. 이러한 결과는 상업가로인 인사동길의 가로만족도는 주 · 야간환경에 따라 그 영향요인이 달라질 수 있다는 것을 의미하며, 주 · 야간별 차별화된 계획이 중요하다는 것을 말해준다. This study selected Insadong Street to identify the influence factors on satisfaction level of night and daytime commercial streets. Insadong Street was divided into sections according to the difference of illumination intensity, and a survey was done on each section per day and night. A hierarchical analysis was also performed. The result shows that first, there was no difference in satisfaction per each section during daytime, but significant difference appeared during nighttime. Second, the influence factor of comfort was the highest during daytime followed by buildings and commercial environment. During nighttime, the influence factor of buildings was the highest followed by streets and continuity, which indicates that the scenic aspect has a powerful influence. This result means the satisfaction level of streets in Insadong Street, which is a commercial street, can have different influence factors during daytime and nighttime, which implies the importance of differentiated plans for daytime and nighttime.

To absorb the deformation of external live load, thermal gradient, shrinkage and creep in bridge structures and general structures, expansion joint has to be established. Especially expansion joint for high-speed railway bridge has to accomodate the static and dynamic forces and it not only has the durability of itself but also maintain the durability of structure by preventing the leakage of water. The actual used product of expansion joint for high-speed railway bridge is only ones made in France, Germany and Japan. In this study, the development process and test results of developed expansion joint are introduced which has the functional operation and durability enough to apply to high-speed railway bridges, roadway bridges and general structures. The tests consist of fatigue-durability test of 3 million times by high-speed rail load, leakage test and jack-up test for verifying the possibility of exchanging it. The performance of developed expansion joint satisfy the specification of Korea High Speed Rail Construction Authority.

PSC box bridges by MSS construction method in high-speed railway may not be cast in place at one step. Web and bottom flange(U member) in the cross section are cast in place at first, then top flange will be cast in place later with some time lag. In this section, stress distributions of U member and top flange are different with those in generally complete cast in place cross section. In the composite section composed of two different aged members, the redistribution of stresses takes place. This results from time-dependent strain characteristics of concrete and the effects of forces applied at the various stages. For comparison in the present paper, two models, one with the composite cross section and the other with generally complete cast in place cross section, are analyzed. The longitudinal stress differences of two models on considering construction stages are compared. As the analysis results show the considerable differences in the stresses of cross section between two models, the composition of cross section is considered for rational design of PSC box girder bridge.

Drying of granules for tablet formulation is one of the important unit operations. The loss on drying method is traditionally used for this purpose. However, it is a time-consuming method, requiring at least 1 h. Moreover, it is ineffective in monitoring the moisture content of granules during the drying process. In this study, online real-time monitoring of moisture content during the drying process was successfully performed using near-infrared (NIR) spectroscopy. NIR spectra were collected during 15 different drying batches for developing a reliable NIR spectroscopic method. Such a large number of batches were used to develop a more robust partial least squares (PLS) model. NIR spectra collected from 12 batches were used for developing the model that was validated by predicting the moisture content of the samples in the remaining 3 batches. The standard errors of predictions (SEPs) in the measurement of batch 1, batch 2, and batch 3 were 0.52%, 0.57%, and 0.56%, respectively. The online NIR spectroscopic method developed in this study was reliable and accurate in monitoring the moisture content during the drying process.

본 연구는 근린상권 활성화를 위한 지속적인 방안으로서 장소애착을 상업시설에 적용시켜 상업시설 유형에 따른 상업활동, 상업시설애착, 지역커뮤니티를 살펴보고 상업활동에 따른 지역커뮤니티와 상업시설애착의 영향관계를 분석하는 것을 목표로 한다. 연구결과 방문빈도가 상업시설애착에 긍정적인 영향을 준 곳은 전통시장으로 나타났다. 둘째, 방문빈도가 지역커뮤니티에 미치는 영향은 전통시장과 Mall형 모두 유의한 것으로 분석되었다. 셋째, 상업시설애착이 지역커뮤니티에 미치는 영향은 전통시장과 Mall형 모두 유의하게 나타났다. 넷째, 방문빈도가 상업시설애착을 거쳐 지역커뮤니티에 미치는 간접효과는 전통시장을 이용할 때에 통계적으로 유의한 수준에서 간접효과를 가지는 것으로 분석되었다. 이러한 연구결과는 상업시설 방문빈도가 주민들의 유대감 형성에 긍정적인 영향을 미치고 있으며, 전통시장 및 소규모 상점들을 이용할 때 방문빈도가 조금 더 높게 나타난 것을 보여줌으로써 소규모의 상업공간이 주민들의 상업시설 방문빈도에 더 긍정적인 영향을 주며, 이를 통해 주민들 간의 교류를 통한 커뮤니티 형성에 효율적인 장소가 될 수 있다는 시사점을 제공하였다. This study aims to analyze the effects of commercial activities, store attachment, and local community according to type of commercial facilities by applying place attachment to commercial facilities as a sustainable plan for revitalizing neighborhood commercial areas and analyzing the influence of local communities and store attachment according to commercial activities. Research shows that the place where the frequency of visit had a positive effect on the store attachment was the traditional market. Second, the effect of visiting frequency on local community was analyzed to be significant in both traditional market and Mall type. Third, the effect of store attachment on local community was significant in both traditional market and Mall type. Fourth, the indirect effect of visit frequency on local community through store attachment was analyzed to have indirect effect at statistically significant level when using traditional market. The results of this study suggest that the frequency of visiting commercial facilities has a positive effect on the formation of the bond of residents, and that the frequency of visiting traditional markets and small shops is slightly higher when using small shops, thereby providing implications that small commercial spaces have a more positive effect on the frequency of visiting commercial facilities of residents and thus can be an efficient place for community formation through exchanges among residents.

본 연구는 전통시장과 Mall형이라는 상업시설의 유형에 따라 상이한 주민들의 이용행태가 지역애착심과 지역커뮤니티에 미치는 영향을 살펴보고자 하였다. 분석결과 첫째, 전통시장을 이용하는 경우에 상업시설 방문빈도가 주민들과의 교류와 지역애착심에 긍정적인 영향을 미치는 것으로 나타났다. 둘째, 주민들 간의 교류가 지역커뮤니티에 미치는 영향과 지역애착심이 지역커뮤니티에 미치는 영향은 세대상지 모두 유의하게 나타났다. 셋째, 방문빈도가 지역커뮤니티에 미치는 간접효과는 용답동과 행당동에서 유의하게 나타났으며, 이는 주민들간의 교류나 지역에 대한 관심이 상업시설 방문빈도에 따른 지역커뮤니티로의 긍정적인 영향을 주는 매개요인으로서 역할을 하고 있음을 보여준다. 이러한 연구결과는 전통시장 및 소규모의 상업공간이 주민들의 상업시설 방문빈도를 더 높이고, 이를 통해 지역애착심 및 지역커뮤니티 형성에 효율적인 장소가 될 수 있음을 보여주었다. This study investigated the effect of different use patterns of the traditional market and mall types on local attachment and community. As a result of the analysis, first, it was found that the frequency of visits to commercial facilities had a positive effect on exchanges with residents and local attachment when using traditional markets. Second, the influence of the exchange between residents on the local community and the influence of local attachment on the local community were significant in all three sites. Third, the indirect effect of visit frequency on local community was significant in Yongdap-dong and Haengdang-dong. This shows that exchanges between residents and interest in the region play a role as a mediating factor that positively influences the local community according to the frequency of visiting commercial facilities. These results show that the traditional market and small commercial space can increase the frequency of visit and become an efficient place for local attachment and the local community.
