  • 건축법에서 재축(再築)이란 '건축물이 천재지변이나 그 밖의 재해(災害)로 멸실된 경우 그 대지에 다시 축조하는 것을 말한다'라고 정의하고 있습니다. 필자는 신축, 재개발, 재건축 등 새로 짓는 것이 건축의 주류인 상황에서 재축된 건축물들을 소개하고 건축의 의미를 돌아보고자 이 연재를 준비했습니다.

  • This paper presents analytical methodologies for remaining life prediction of plain concrete structural components considering tension softening and size effects. Non-linear fracture mechanics principles (NLFM) have been used for crack growth analysis and remaining life prediction. Various tension softening models such as linear, bi-linear, tri-linear, exponential and power curve have been presented with appropriate expressions. Size effect has been accounted for by modifying the Paris law, leading to a size adjusted Paris law, which gives crack length increment per cycle as a power function of the amplitude of a size adjusted stress intensity factor (SIF). Details of tension softening effects and size effect in the computation of SIF and remaining life prediction have been presented. Numerical studies have been conducted on three point bending concrete beams under constant amplitude loading. The predicted remaining life values with the combination of tension softening & size effects are in close agreement with the corresponding experimental values available in the literature for all the tension softening models.

  • 철도, 항공 및 기계구조물등의 많은 설계문제에서는 반복하중의 영향을 받기 때문에 제조와 품질제어 공정에서 특히, 반복하중의 영향이 심한 구조부품의 피로균열에 대한 연구가 충분히 선행되어야 한다. Paris법칙에서 응력확대계수범위 .DELTA.K에 10%오차를 수반하면 피로수명 N에는 50%정도의 오차를 초래할 만큼 민감도가 매우 크다. 그러나, 선형탄성파괴역학에 근거한 p-version 유한요소법은 응력확대계수를 산정하는데 있어서 종래의 h-version 유한요소법에 비해 훨씬 적합함이 증명되고 있다. 제안된 해석법의 효율성을 입증하기 위해 철도차량의 연결접합부에 있는 T-joint부위의 피로균열해석과 원공이 있는 유한판의 원공주위에서 발생되는 균열해석이 수행되었다.

  • In this paper, a statistical analysis of fatigue crack growth behavior under constant amplitude loads has been carried out. Fatigue crack growth tests were conducted on sixteen pre-cracked compact tension (CT) specimens of the pressure vessel (SPV50) steel in controlled identical load and environmental conditions. The assessment of the statistical distribution of fatigue crack growth experimental data obtained from SPV50 steel was studied and also the correlation of the parameter C and m in the Paris-Erdogan law was discussed. The probability distribution function of fatigue crack growth life seems to follow the 3-parameter Weibull. The fatigue crack growth rate seems to follow the 3-parameter Weibull and the log-normal distribution. The coefficient of variation (COV) of fatigue crack growth life was observed to decrease as the crack grows. A strong negative linear correlation exists between the coefficient C and the exponent m in Paris model. Fatigue crack growth rate data shows a normal distribution for both m and logC.

  • This study investigates the analysis on the acceptance of Foreign Fashion trends in Korean Fashion Collection by collections, years, season, and designers. The purpose of this study is Korean collection's degree to adopt and receive foreign collections, by comparative analysis of design features between Seoul and foreign collections. For such purpose, from 2006 S/S to 2011 F/W, 5185 pictures were collected from designer's photos of Seoul, Paris, Milan, NY, and London collections. The content analysis and statistical analysis using SPSS will be conducted for data analysis. The results of the research are as follows. First, regarding the design features, square-form silhouette, achromatic colors, and none pattern were presented as well. Second, there were significant differences in the design characteristics of each year. Particularly, in 2008, X-form silhouette, Yellow and Green color, and flower pattern were emphasized. Third, the design features by season were significant differences. In S/S season, square-form and X-form silhouette, achromatic colors of white and gray color, none pattern were evident while in F/W season, square-form Silhouette, achromatic colors of black and gray, and none pattern were emphasized. Fourth, the design features by designer are as follows. In terms of form, Seoul collection was influenced by Paris collection. In terms of colors, it was influenced by NY and London collections.

  • The new climate regime for practical reduction in green house gas(GHG) emissions was launched in Paris at Dec. 2015. The Korea government would make various policies and plans in order to achieve the BAU 37 % emission reduction goals by 2030. In this study, the current situation and the possible corresponding methodology to the GHG emission reduction of Korea paper industry were investigated. Although the GHG emission reduction in KOREA paper industry has been successfully conducted compared with other industries until now, the more efforts for controlling GHG emission would be required to meet the new climate regime. The efficiency of various GHG reduction projects conducted by Korea paper companies was evaluated to find efficient way for GHG reduction. The certified methodologies of the external project based offset systems in Korea GHG emission trading scheme were also reviewed for providing the possible way to develope tailored methodology to the Korea paper industry.

  • This study supplements clothes by studying pleasure shown in accessories of haute couture designers and finds out pleasant characteristics represented in items which play an important role in producing personalities through collections, so the study aims at prospecting design development directions accessories henceforth. For the study period and methods, 295 photo materials were analyzed being judged to show pleasure centered on Mode et Mode, representative fashion magazine, from 2005 S/S Paris haute couture collections to 2013 S/S Paris haute couture collections. At this time, the photos analyses were conducted and selected by two experts (Ph. D holders majored in fashion design) through two times. After analyzing pleasure features represented in fashion collection focused on haute couture accessories, I could know that surrealistic pleasure, anonymity-expressing pleasure, natural pleasure, and exaggerative pleasure were shown. The pleasure, as element that supplements and emphasizes clothes, has had an effect on bringing laughs characteristically.
