몇 년전 TV에서 강원도 고성군에서 꾸지뽕나무를 농경지에 집단으로 재배하여 그 잎에서 즙을 내여 칼국수를 만드는 것을 보았는데, 또 다른 매체에서는 이 나무를 골목으로 상황버섯을 종균을 접종시켜 재배하면 일반 골목 재배보다 항암 효과가 높은 버섯을 생산한다고 하고, 이 잎을 먹인 누에를 성인병 예방이나 치료약으로 사용하기 위해 최근들어 여기저기서 소득 작목으로 대량재배가 이루어지고 있다. 최근들어 꾸지뽕나무가 치료가 어려운 질병의 치료약으로 혹은 건강식품으로 찾는 이들이 많아졌다.

In order to investigate the ability of log wood for oak mushroom production as a source of an alternative energy, both chemical and physical characteristics of log wood were investigated according to the cultivation periods. Also, both chemical and physical characteristics of material that treated by steam explosion were investigated to confirm the pretreatment effect by remaining enzyme as a control. The contents of ash, water-, alkali- and organic soluble extracts have been increased after the inoculation. It appeard that holocellulose contents substantially decreased and the contents of lignin as another main component of wood remained constant after the inoculation. However this result implied that indeed, a sufficient amount of lignin has been degraded paritially by enzymes of oak mushroom Lentinus edodes if we consider that the amount of holocelulose was substantially reduced. It also indicated that the degree of degradation gradually progressed but crystallinity decreased after the inoculation. The contents of water-, alkali- and organic soluble extracts have been increased by steam explosion. Holocellulose contents increased within narrow limits and lignin contents remained constant. However the contents of holocellulose and lignin have been decreased by steam explosion, considering that the amount of other extractives was relatively increased. The degree of crystallinity and lignin contents reduction by steam explosion was almost similar to the result obtained by increasing cultivation periods. According to the results, log woods for mushroom production have a potential as material for developing alternative energy.

Sound absorption coefficients of oak (Quercus mongolica) wood and oak mushroom bed log were measured by the two microphone transfer function method and anatomical features of oak mushroom bed log examined by stereo scope and SEM observations. The sound absorption coefficients of oak mushroom bed log seemed to be higher than those of normal oak wood specimen over all estimated frequency range. Especially, in the frequency range of 2 to 6 kHz, they were about 2~3 times higher than those of normal wood specimen. Due to fungi degradation, the specific gravity of oak mushroom bed log decreased about 70% than that of normal wood. For oak mushroom bed log, abundant pores occurred on the radial, tangential and cross sectional surface and it was considered that the pores behaved as a sound absorbing pore.

Studies were conducted to investigate the changes of teleomorph of Diatrype stigma on bed-log of shiitake (Lentinula edodes) and appearance of secondary harmful fungi from December 1999 to August 2001. The color of stroma was changed from red brown to dark brown after 12 months. The size of ostioles became smaller and the number of ostioles decreased as time passed. Most of the ostioles disappeared after 20 months from toleomorph formation. Perithecia and ascospores were gradually disappeared, and perithecia containing ascospores were observed at 10% of bed-logs tested after 20 months. Concerning the secondary harmful fungi infecting the bedlog of shiitake after teleomorph of D. stigma, Hypoxylon truncatum (Anamorph : Nodulisporium sp.), Schizophyllum commune and Trichoderma spp. were observed on stroma of D. stigma. Penicillium sp. occurred on spore-horn of Libertella sp. (Anamorph of D. stigma). Besides, Hypoxylon howeianum and some species of Myxomycetes were observed. Also, Libertella sp. appeared again at some bed-logs.

Revitalized alley-type urban commercial streets have recently received a lot of attention as a preferred place for people. The purpose of this study is to present implications in the planning and design methods for the making of alley-type urban commercial street. For that, theoretical review and case analysis were conducted on the street spatial characteristics of 'Jeonridan-gil' and 'Mangmidan-gil' in Busan, about site overview, street spatial composition, building use, streetscape and street furniture. The implications through the study are as follows. (1) Street environment should be created to improve the pedestrian space and environment. (2) The existing main use and the newly introduced use need to be coexisted. (3) The identity of the street must be maintained through adaptive reuse, etc. (4) The voluntary formation of the private sector and the planned making of the public need to be cooperated.

According to data released by the Covid 19 Self-Employed Emergency Response Committee, 95.6% of small business sales due to Covid 19 have decreased over the past two years, and the damage has further increased due to social distancing for quarantine. However, as all social distancing guidelines have rebeen lifted, and the commercial district has been revitalized, the Seoul Metropolitan Government is pushing for a project to foster local brand commercial districts so that small business owners or prospective founders who have closed their businesses due to the prolonged COVID-19. Therefore, this study propose the model that recommends alley commercial districts suitable for founders among the five alley commercial districts selected for the project to foster local brand commercial districts in Seoul. The Seoul Metropolitan Government's local brand alley commercial recommendation system recommends major population age groups and major industries in the commercial district by combining the population perspective model using Xgboost and the commercial district characteristic model using Decision Tree.

This study analyzed the opinions of residents for desirable urban regeneration and suggested an improvement plan for alley environments. This study conducted a questionnaire survey of the residents living in Alley Garden of Bisan 2,3-dong, Daegu Metropolitan City. In the analysis of the importance and satisfaction of Alley Garden components, items related to a safe, cleanly environment such as 'Lighting facility installation', 'Sewage and waste disposal' and 'CCTV installation' had a high level of importance. It was also found that items improved by the Residential Environment Improvement Project and Alley Garden such as 'Lighting facility installation', 'Quantity of herbaceous flowers' and 'Kinds of herbaceous flowers' had a high level of satisfaction. The IPA results showed that items such as 'Empty house maintenance', 'Rest facilities such as benches and pergolas', 'Space for resident interaction' and 'Public parking lot' had a high level of importance, but had a low level of satisfaction, which suggests that they should be improved by priority. As a result of factor analysis, Alley Garden components were classified into four factors: 'Safety and cleanliness', 'Greenness', 'Exchange and convenience facility' and 'Aesthetics renewal'. Based on this classification, a regression analysis was conducted regarding the effects of the four factors on overall satisfaction. Results showed that all four factors had a significant influence on the overall satisfaction and that 'Aesthetics renewal' and 'Safety and cleanliness', respectively showing levels of significance at 0.274 and 0.235, were highly influential to overall satisfaction. Therefore, it was concluded that spaces for resident interaction and rest facilities should be preferentially installed to improve the environment of alleys. For the improvement of the overall satisfaction of alley environments, it was also concluded that residents should be encouraged to engage in activities such as sculpture installation and mural drawing, along with the introduction of safety bells and crime prevention environment design and the implementation of alley beautification projects.

How can we explain the phenomenon of small, old alleyways in the city becoming rising commercial places attracting people from an aesthetic perspective? This research discusses distinctive aesthetic experiences of urban commercial alleyways, which are located on inner roads and consist of small-scale stores and explore the specific aspects of Sharosu-gil, located in Gwanak-gu, Seoul. The aesthetic experience of urban commercial alleyways is generated by the contrast with the refined urban fabric along main roads in terms of space, the gap between the old and the new, and the antagonism between the known and the less known. The approach to Sharosu-gil consists of the high-rise buildings along the main road built in the 2000s, then encountering low-rise buildings on inside roads built from the late 1970s to the present. Therefore, it is judged that the site has sufficient conditions to generate the aesthetic experience as an urban commercial alleyway. As a result of analyzing the street improvement projects, first, the official announcement of the name 'Sharosu-gil' was interpreted as an escape from the place specificity and garnered the acquisition of the characteristics of an alternative. Secondly, the improvement project for old-established signboards was interpreted as harmony between the new and the old and the loss of temporality. Thirdly, in the pedestrian priority road project, the pavement was interpreted as a reinforcement of the identity as an alleyway and the visualization of the area. Since the reality of urban commercial alleyways depends on the user's visiting, it is necessary to interpret alleyways from the perspective of the senses and aesthetics, not just from social phenomena or capital logic perspective. The study will cast implications for relevant schemes and data-driven research.

표고버섯(Lentinus edodes) 균에 의한 졸참나무(Quercus serrata)골목의 미시형태적 변화를 주사형전자현미경 (SEM)을 통해 관찰하였다. 표고 재배 5년후 골목의 중량 감소율은 50%에 달했다. 구성세포중 목섬유는 표고균사에 의해 쉽게 분해되었으나 도관과 유세포는 저항성을 나타냈다. SEM 관찰 결과 표고균사는 세포내강(內腔)에서부터 세포벽을 서서히 분해 박벽화(薄壁化)시켰으며, 또한 Cell corner가 중간층보다 먼저 공격을 받아 분해 되었으나 중간층은 쉽게 분해되지 않았다. 흥미롭게도 연부후(軟腐朽)의 전형적 형태인 2차막에서의 공동(空洞)역시 백색부후균인 표고균사에 의해 형성 되었다. 이상의 관찰결과 표고균은 백색부후와 연부후균이 갖는 미시형태적 특징을 동시에 보여 주었다. 아울러 중간층 보다 Cell corner가 먼저 선택적으로 분해되며, 도관세포벽의 분해저항성을 세포벽 구성 리그닌의 화학적 특성과 연관시켜 논의했다.
