본 연구는 시판 배추김치, 총각김치, 깍두기 및 파김치에서 분리한 젖산균을 15℃와 25℃의 온도에서 배양하였을 때아질산염의 소거 효능을 확인하였다. 15℃에서, 시판김치에서 분리된 젖산균은 L. mesenteroides subsp mesenteroides와 L. paramesenteroides를 제외하고는 매우 활성적으로 아질산염을 소거시켰다. 특히 L. mesenteroides subsp dextrinicum과 L. lactis는 아질산염에 적응하는 기간을 필요로 함이 없이 매우 활성적으로 아질산염을 소거시켰다. L. sake, L. plantarum, L. casei subsp. pseudoplantarum 및 L. coryniformis subsp. torquens는 하루 정도 아질산염에 적응하는 기간을 거친 이후에 매우 활성적으로 아질산염을 소거시켰다. L mesenteroides subsp. mesenteroides는 하루가 경과된 이후에 비교적 활성적으로 아질산염을 소거시켰다. 그러나 L. mesenteroides subsp. mesenteroides는 다른 균종에 비하여 매우 낮은 아질산염 소거율을 나타내었다. 25℃에서, 시판김치에서 분리된 모든 젖산균은 아질산염에 적응하는 기간을 필요로 하지 않았으며, L. paramesenteroides를 제외하고는 매우 활성적으로 아질산염을 소거하였다. 또한 시판김치로부터 분리된 젖산균은 L. mesenteroides subsp. mesenteroides와 L. paramesenteroides를 제외하고는 1일 이후에, L. mesenteroides subsp. mesenteroides는 2일 이후에 90% 이상의 아질산염을 소거시켰다. 그러나 L. paramesenteroides는 25℃에서도 활성적이지 못하여 다른 균종에 비하여 아질산염의 소거 능력이 매우 낮았다. 한편, 다른 김치 기원의 동일 균종의 Lactobacilli와 L. mesenteroides subsp. mesenteroides 및 L. paramesenteroides를 제외한 Leuconostocs는 15℃에서는 물론 25℃에서 매우 활성적으로 아질산염을 소거시켰다. This study confirmed depletion efficiency of nitrite when incubate lactic acid bacteria was isolated from commercial Chinese cabbage pickles (Baechu kimchi), pickled ponytail radishes (Chongkak kimchi), radish cube kimchi (Kaktugi) and pickled Wakegi (Pa kimchi) at temperatures of 15℃ and 25℃. At 15℃, lactic acid bacteria isolated from commercial kimchi depleted nitrite actively except Leuconostoc mesenteroides subsp. mesenteroides and Leuconostoc paramesenteroides. In particular, Leuconostoc mesenteroides subsp. dextrinicum and Leuconostoc lactis depleted nitrite by very actively without period adaptation in nitrite. Lactobacillus sake, Lactobacillus plantarum, Lactobacillus casei subsp. pseudoplantarum, and Lactobacillus coryniformis subsp. torquens depleted nitrite very actively after 1 day. L. mesenteroides subsp. mesenteroides depleted nitrite relatively actively after 2 days pass. In contrast, L. paramesenteroides displayed very low nitrite depletion ratio compared to other species. At 25℃, all lactic acid bacteria isolated from commercial kimchi did not need adapting period in nitrite, and depleted nitrite very actively except L. paramesenteroides. Also, all lactic acid bacteria except L. mesenteroides subsp. mesenteroides and L. paramesenteroides nitrite of more than 90% after 1 day, and L. mesenteroides subsp. mesenteroides depleted nitrite of more than 90% after 2 days. However, because L. paramesenteroides was not active even at 25℃, nitrite depletion efficiency was very low compared to other species. On the other hand, the same species of Lactobacilli and Leuconostocs except L. mesenteroides subsp. mesenteroides and L. paramesenteroides of other kimchi origin at 15℃ as well as 25℃ by vitality depleted nitrite very actively without statistically significant difference (p<0.05).

The aim of ensuring additional economics of building by reducing energy consumption and security of environmentally friendly performance of building are another important design objectives and criteria of remodeling. Accordingly, various certification systems and guidelines as a variety of design techniques have been proposed to ensure comfort of building occupants by improving environmental performance elements, such as light, heat, noise, airflow and etc. However, the development in quantitative evaluating and verifying techniques of environmental performance has not been provided as solidly as its stipulative background. BIM (Building Information Modeling), emerged as a new design technique, is able to ensure reliability and quantification of the proposed design through linking and utilizing BIM data for environmental performance analysis. The ability to analyze the environmental performance of BIM has been case studied, and they have emerged as big issues in the 2010s. In this study, BIM data utilization methodologies and applications in various areas for remodeling projects are sought. In addition, the environmental and energy performances analysis process that is useful in design practices for remodeling business is proposed.

Recently, in the field of construction, many researches to form 3D space information using BIM data and utilize BIM object information in architectural space into the process of implementing green building have been actively conducted largely by the industry-university-institute research agencies depending on the field of energy and environmental specialization. However, there are few quantitative evaluation criteria and specified methodologies in assessing environmental quality level depending on every field of light, sound, heat, and air current and also little performance evaluation in the field of energy for green remodelling of the existing architecture compared to the activated research topics. Accordingly, this study formed space information using BIM data and conducted a study on the measures to analyze and evaluate energy and environmental quality level of unit building more quantitatively and easily through shape and property information embedded in formed space information. Through this, this study analyzed BIM data linking process in the process of entering building shape information and organized BIM-based energy performance analysis input variable-utilizing process establishing plans for green remodelling. Through such a research process, this study aims to propose green remodelling energy performance analysis process improvement plans as evaluative methodology using BIM-based object information by linkable input variable items by field of energy quality level.

Over the course of simulation performances, the existing buildings’ current situation of energy consumption is diagnosed, and the effect of improving energy performance is predicted in early planning stage. However, it is difficult to ensure the level of information required to perform the simulation. The main issues are the aging condition assessment, omission of required information of the building, and the differences between the documentations and the actual status of the existing building. BIM-based building information is able to digitalize and organize the documented building information and add changed or missing information in the field thereafter. In addition, a variety of tools and information increasing the compatibility are opening the potential uses for the remodeling. However, utilizing BIM for remodeling is not the norm, and the feedback-able actual operational problems information is insufficient. In this paper, the possibility of utilizing BIM-based remodeling is analyzed through a comparison of the existing and the BIM-based building energy analysis process of remodeling, and then the optimizing methods of remodeling process of the existing building is sought.

Recently, green-remodeling has been highlighted due to the rapid growth of energy consumption. However, the authors came across several difficulties in establishing a green-remodeling system in place. The issues are as follows : (1) user’s subjective judgements (2) lack of information of green-remodeling (3) wasting cost and time by a lot of trial and errors. So, the purpose of this paper is to develop a passive and active element technique classification system for the green-remodeling database. The classification system of green-remodeling consist of four fields (exterior envelop, thermal source & air conditioning system, lighting system, renewable energy) and five steps. (1) step 1,2 : investigation of the present condition of the building (2) step 3 : establishing a direction of construction (3) step 4,5 : choice of energy-saving technology. Each of steps has a detailed and systematic standard. As a result, non-experts (architects, owners) can understand whole process of green-remodeling more intuitively and save a lot of time and cost by element technique classification system developed in this study.
