This study examines the characteristics of the herbaceous vegetation structure of Haneul Park District in World Cup Park, which had previously been used as a landfill for 15 years. The survey was carried out through actual vegetation and vegetation structures from 2003 to 2006, biannually. Firstly, as a result of analysis of actual vegetation, the autumn season changed more quickly over the 2 year span than did the spring season in terms of actual vegetation area. Annual plants increased for the initial $3{\sim}4$ years and then perennial plants increased. Secondly, the results of analysis in vegetation structure are as follows: 1. The number of planted species gradually decreased. 2. Miscanthus sinensis var. purpurascens of the control region was maintained but Imperata cylindrica var. koenigii of the non-control region was invaded by Miscanthus sacchariflorus, Glycine soja and Phragmites communis etc. 3. Planted species in the control region were maintained in superior state, but the non-control region was changed by natural occurrence plants until 2006, the fourth year. 4. Physostegia virginiana and Aster koraiensis which were planted in the non-control region were maintained but most of planted species weakened and changed by natural occurrence plants including Erigeron annuus, Artemisia princeps, Setaria faberii and Phragmites communis etc. Based on the results, we suggested the management method of herbaceous vegetation in the Haneul Park District.

본 연구는 북한산국립공원 둘레길의 정상정복형 수직 탐방객의 분산 효과를 진단하고, 둘레길 구간별 특성화 및 개선방향을 제공하는데 목적이 있다. 조사방법은 이용자 자기 기입식 조사 방법으로 현장조사를 통해 둘레길 전체 21개 구간에서 탐방객을 대상으로 이루어졌다. 둘레길 조성 후 북한산 탐방 횟수가 증가하였으며, 둘레길에 처음 방문한 만 18~29세의 젊은 연령층 비율이 높아, 둘레길로 인해서 새로운 계층의 탐방객이 유입된 것으로 판단된다. 북한산 정상탐방 이용빈도는 '감소하였다' 7.6%, '증가하였다' 46.2%로 정상정복형 수직 탐방객의 분산효과는 아직 없는 것으로 판단된다. 둘레길 만족도는 7개의 측면 중 여가장소적 측면이 3.74, 보행만족 측면이 3.61로 높았고, 역사문화 측면이 3.09로 가장 낮았다. 둘레길 구간별 특성과 탐방객의 방문동기, 만족도 결과를 통해 둘레길이 가벼운 운동, 산책 등의 건강증진을 위한 개념으로 인식되고 있음을 보여주었다. 그러나 저지대 길에서의 자연, 생태, 역사, 경관 등 국립공원 자원에 대한 다양한 시각의 이용문화가 창출되어 장기적으로 긍정적인 효과를 예상할 수 있었다. 또한 둘레길의 구간별 특성과 여건, 인프라 및 프로그램에 따라 차이가 있어 둘레길 구간별 특성을 고려한 인프라 및 프로그램이 보완된다면 장기적으로 정상탐방객의 저지대 탐방문화 유도 효과를 기대할 수 있을 것이다. The purpose of this study is to evaluate the effect of Dulegil in Bukhansan National Park in dispersing peak climbing hikers, characterize each section of Dulegil and suggest ideas of improvement. This study was conducted based on the survey completed by visitors in all 21 sections of Dulegil. After the construction of Dulegil, the number of visit to Dulegil grew and it was analyzed that Dulegil attracted new visitors given that the rate of young people(aged 19~30) who visited for the first time was quite high. Regarding the frequency of peak climbing, 7.6% of the respondents said "decreased" and 46.2% said "increased", showing that Dulegil's effect to disperse peak climbing hikers is nominal. Seven qualities were evaluated regarding Dulegil's level of satisfaction. Out of those seven, the quality of recreational place and taking a walk achieved high scores of 3.74 and 3.61 respectively. The quality of culture and history scored the lowest with 3.09. The analysis on the characteristic of each section of Dulegil, reason of visit, and the visitors' level of satisfaction showed that Dulegil is now regarded as a place where they can improve their health through light exercise and walking. In addition, a positive effect can be expected for a long time since there are different ways of utilizing the resources of the National Park, such as getting in touch with nature, preserving ecology, learning history and enjoying beautiful landscapes. If infrastructure and programs specific to each section of Dulegil were improved in a long-term perspective, it would be effective to encourage peak climbers and enjoy the lower parts of the mountain.

Thermal resistance of dried bacterial spores against dry heat was determined. Spare suspensions of Bacillus subtilis var. niger ATCC 9372, Bacillus stearothermophilus Oxoid Code BR 23 and Clostridium sporogenes ATCC 19404 were located on aluminium strips, dried in electric oven under vacuum at room temperature for 10 minutes. The aluminium strips were laid in the middle of gas flow (hot air and superheated steam) with the velocity of 6 m/sec and heated at $120^{\circ}C$ for 180 seconds. The calculated D-values showed that there were no remarkable differences in the heat resistance of bacterial spares between $R.H.\leqq0.012$ and R. H.=0.51. Furthermore the thermal resistance of B. subtilis spores to dry heat was greater than that of B. stearothermophilus.

산지형 도시공원 내 보행약자를 위한 산책로 조성 연구 -우면산도시자연공원을 대상으로-

This study was undertaken to provide a basis for planning trail standards, providing rights of movement, improvement of health and the experience of nature for at-risk walkers for application to the Umyen Park site. This study researched related laws, manuals, scholastic writing and the established site, a raku-raku mountain trail in Osata, Japan. By referencing these results and similar standards, a conceptual trail plan for at-risk walkers was created. The plan suggests five points -- accessibility, convenience, social aspects, economic efficiency, and environmentally-friendliness -- and referenced an evaluation of outdoor living environments for the elderly. The planning standards are comprised of four steps that are ranked in order and are related to the selection of location, trail structure, route patterns, and equipment. Plans for trails catering to at-risk walkers in Umyen Park were then based on these standards. As a result, it was found that the mountain has both a high elevation and abundant natural resource, both of which must be taken into account during planning. This study is valuable because it is one of the first studies of trail plans for at-risk walkers made in mountainous urban parte. Subsequent research can use the standards of this study for further evaluation while future modifications must reflect changing needs and details. 본 연구는 보행약자의 이동권 확보와 건강증진 및 체험공간 제공을 위하여 산지형 도시공원성 기준 내 산책로 조성을 목적으로 조성기준을 수립하고 실제 사례지에 적용하였다. 문헌 및 사례연구를 바탕으로 보행약자 산책로 조성의 개념을 제시하고 관련된 유사기준을 참고로 산책로 조성 기준을 마련하였다. 보행약자 산책로 조성 개념은 노인주거시설 외부환경 설계 개념을 근거로 접근성, 편의성, 사회성, 경제성, 자연친화성의 5가지로 제시하였고 조성단계별 적용방안을 도출하였다. 산책로 조성 기준은 순서에 따라 입지적지 선정, 노면구조 설정, 노선배치, 시설배치의 네 단계로 구분되며 각 단계별 조성 기준을 제시하였다. 산책로 조성 기준을 우면산도시자연공원에 적용하여 보행약자 산책로 조성입지 선정, 노선배치 및 시설배치를 실시하였다. 그 결과 조망점과 탐방자원이 풍부한 산지에 완경사의 산책로 조성은 한계가 있었으나 우리나라 보행약자 산책로 조성의 초기 연구인 점에서 본 연구의 가치가 있으며 향후 본 연구결과를 기초로 산책로 조성을 실시하고 이용 후 연구를 통해 세부적인 사항들에 대한 심도 깊고 현실성 있는 기준 제시가 필요하였다.

In Previous paper, an experimental equation for prediction of thermal diffusivity of white muscled fish meat paste products was suggested. In this paper, another experimental equation for red muscled fish meat paste products was derived. The thermal diffusivities of products with water contents of 44.74 to $82.83\%$ and lipid contents of 0.35 to $23.38\%$ could be deduced as following equations ; $$\alpha_{80.39^{\circ}C}=0.0759{\cdot}10^{-6}{\cdot}X_w+0.0836{\cdot}10^{-6},\;m^2{\cdot}s^{-1}$$ $$\alpha_{100.63^{\circ}C}=0.0820{\cdot}10^{-6}{\cdot}X_w+0.0853{\cdot}10^{-6},\;m^2{\cdot}s^{-1}$$ $$\alpha_{120.09^{\circ}C}=0.0830{\cdot}10^{-6}{\cdot}X_w+0.09140{\cdot}10^{-6},\;m^2{\cdot}s^{-1}$$ The experimental equation derived from these equations was ; $$\alpha=(0.9795+.8996{\cdot}X_w){\cdot}\alpha_w-0.0709{\cdot}10^{-6}{\cdot}X_w-0.0779{\cdot}10^{-6},\;m^2{\cdot}s^{-1}$$ The errors of the thermal diffusivities of red muscled fish meat paste products predicted with this equation were less than ${\pm}\;0.52\%$ compared with those measured. A new experimental equation for products of white and red muscled fish meat paste could be discribed as follow ; $$\alpha=(1.096+0.5318{\cdot}X_w){\cdot}\alpha_w-0.0057{\cdot}10^{-6}{\cdot}X_w-0.0992{\cdot}10^{-6},\;m^2{\cdot}s^{-1}$$ The errors of the thermal diffusivities predicted with this equation were less than ${\pm}\;0.13\%$ compared with those measured.

In this paper, the influence of heating medium on the thermal diffusivities of fish meat paste products was studied. Model products were heated in boiling water, saturated steam and soybean oil. The differences in temperature raise of the products were interpreted with Biot number of the products. Because of the large overall heat transfer coefficient of heating medium, the temperature raise of the products in boiling water and saturated steam was fast and the Biot number of the products could be recognized as infinite. But the temperature raise of the products in soybean oil was slow and the Biot number of the products was less than 50.

This study was carried out to design a bridge-type ecological corridor plan in a forested neighborhood park affected by road construction in Dongjak-gu, Seoul. In order to study the site conditions, we analyzed topography, ecosystem structure, and user behavior and trail use. Existing vegetation was classified into 12 types. Based on a vegetation analysis, the Populus albaglandulosa and Robinia pseudoacacia communities, where planted species are dominant, were distributed extensively in the southern forest area. Planted areas with a single-layer structure of Korean landscape woody plants and Robinia pseudoacacia communities with a single-layer structure were distributed extensively in the northern forest and water-supply area. Based on a study of 28 quadrats, the similarity index between the multi-layer plant communities distributed in the southern forest and the single-layer planted areas was low. Twenty-four species of wild birds(355 individuals) were found in the survey area, including nine interior species and three urban species. The study of user behavior and numbers showed most users were walkers and few users were observed in the southern forest while most users were observed in the northern forest and water supply area. We selected some wild birds as model species to represent migrating species believed to use this park as an ecological corridor during migration. We suggested the new park plan include the following: improvement of vegetation structure for wildbird migration and habitat, connection of park trails for users and presentation of a landscape linked to nature.
