  • Most of countries differ from their favors, in Taiwan fruit juice and sweet taste are emphasized while external appearance in Japan. During transportation, movement of the container, fluctuation of temperature, decrease of the fruit freshness and undesirable packing materials tend to decline fruit marketability. For these problems, it is believed that shortening of boarding time by utilization of plate and styro form box for packing, the author believed.

  • Present status of Japanese wetland ecosystems and several trials towards rehabilitation and restoration of them are reviewed. Most of wetlands are altered to paddy fields and city areas, and natural wet lowland including tideland is the most endangered nature in Japan. Not only the preservation of natural wetlands but also the conservation of secondary nature of paddy field and waterways in traditional rural areas and restoration of original nature in city areas became the most concerned theme for nature conservation according to the national strategy for the biodiversity conservation. Not only the technological development based on the conservation ecology, but also the development of mitigation banking system are needed in Japan.

  • 응고제의 종류에 따른 천연물 첨가 두부의 제조특성을 알아보았다. 수율과 물성, 관능검사결과 등을 고려한 결과 $MgCl_2$는 0.2%, $CaCl_2$ 0.4%, $CaSO_4$는 2.0%가 최적농도로 선택되었다. 또한 천연물 첨가농도는 당근 4%, 오이 10%, 시금치 1.0%, 녹차말차 0.05%를 최적농도로 선정하였다. GDL을 응고제로 사용한 천연물 첨가두부의 색도도 응고제의 종류에 따라서도 차이를 보이지 않았으며 두부의 물성에도 크게 영향을 미치지 않았다. 당근, 오이, 시금치 첨가두부에서 색소의 함량은 $MgCl_2$, $CaCl_2$를 응고제로 사용한 두부에서 함량이 높았으나 녹차 첨가두부의 polyphenol 함량은 $CaSO_4$, GDL를 응고제로 사용한 두부가 높은 값을 보였다.

  • 두부의 품질을 고급화하고 다양화하기 위한 방안의 하나로 천연물을 첨가한 두부를 제조하여 기능성의 부여와 함께 기호성을 향상할 수 있는 천연물 첨가두부를 제조하였다. 천연물로는 클로로필과 카로티노이드를 가지고 있는 당근과 오이, 시금치 그리고 카테킨등에 의한 기능성이 확인된 녹차를 천연 첨가물로 선정하였다. 천연물 첨가두부의 수율은 무첨가 두부에 비하여 감소되었으나 색상에 의한 기호성의 증대를 확인할 수 있었다. 천연물 첨가에 따라 두부의 조직특성은 큰 변화가 없었으나 기호도 향상의 효과가 있었다. 최적 첨가 농도는 당근 4%, 오이 10%, 시금치 1.0%, 녹차는 0.05%로 결정할 수 있었다. 저장 중 총균수의 변화는 시금치와 녹차 첨가두부가 저장초기 균의 생육을 저지하여 저장성이 있는 것으로 나타났다.

  • 천연기념물은 자연적 가치와 문화적 가치가 복합된 자연유산으로 매우 다양한 가치를 내포하고 있는 문화재이다. 시간이 지남에 따라 "문화재보호법" 상 천연기념물의 지정기준 및 천연기념물의 의미도 점차 변화되고 있다. 점차 식물의 희소성 및 학술적 가치 외에도 역사적, 민속적, 경관적 가치도 중요해지고 있으며, 이에 따른 천연기념물의 지정 및 관리 유형 개선이 필요한 시점이다. 하지만 현행 유형은 식물의 행태적 특성에 초점이 맞춰져 있어 식물의 다양한 가치를 포괄하는데 한계가 있고 "문화재보호법"의 문화재 정의 및 지정기준과의 연계성도 부족한 실정이다. 이에 따라 본 연구는 문화재로서 식물의 복합적인 가치를 담을 수 있도록 전문가 델파이 조사를 통해 천연기념물 식물의 신규 유형을 제안하고 향후 다양한 천연기념물 발굴에 이를 활용하고자 하였다.

  • Preservation space is a functionally$\ulcorner$core$\lrcorner$in a museum. Gernerally, it is a common view that collections are exhibited within 5% of total stored collections. So that, part of collections are cycled exhibition space centering around preservation space, and that is a important mechanism of collections circulation in a museum. It is the best way that collections should be $\ulcorner$conserve$\lrcorner$ in a stable condition, but inevitably collections are exposed as stable condition, but inevitably collections are exposed as called $\ulcorner$exhibition$\lrcorner$. For that reason the function of $\ulcorner$exhibition$\lrcorner$. For that reason the function of $\ulcorner$exhibition$\lrcorner$for 'showing' and the function of $\ulcorner$preservation$\lrcorner$for 'conserve'are contrary to each other's concept, so it is principle of scheme that these concepts should be functionally connected with and planned$\ulcorner$match$\lrcorner$. In addition, various studies (for example, comparative analysis of collections, examination of collections for conserved condition or special exhibition, and classification of new item, etc.) are worked in preservation space. Therefore, preservation space should not be considered as a warehouse, should be composed not only$\ulcorner$comfortable place to rest of collections$\lrcorner$but also $\ulcorner$part of study room$\lrcorner$in a museum. So that, environment of museum should be established by plan to preservation and management. The point of plan to museum is that minimize dangerous element for collections, and then develop an essencial element of space for$\ulcorner$conservation$\lrcorner$and$\ulcorner$exhibition$\lrcorner$. The reason why with a few exceptions (buildings which have being exposed or extremely minor part of collections) most of collections have been lasting its life during over hundreds of years with adapting itself to natural features, so scheme of preservation facilities should be made up with understanding and analysis generic character of collections, and then establish proper temperature and humidity environment.

  • In 1987, The Brundtland Report defined a sustainable development as the development that meets the needs of the present without compromising the ability of future generations to meet their own needs. This is the concept that we should cling to, to preserve natural resources of the present for the future generation. With this concept in mind, this paper criticized that the current waste management policy has been neglecting resource preservation aspect of waste management policy while giving too much emphasis on reducing waste generation. Thus, the purpose of this paper is to analyze how waste management policy can affect preservation of natural resources, and to investigate policy alternatives that can reduce both the volume of waste generated and the amount of natural resources that need to be consumed in the production process. The study was conducted based on the literature survey and system dynamics simulation. Borrowing Randers and Meadows's solid waste model with some modification of parameter and variables, this paper simulate several policy alternatives to figure out the most effective waste management policy set that can meet the need of the present without compromising the ability of the future generation to meet their own needs. Main concern was how to link waste management policy with resource management policy that can lead to minimization of waste generation and resource consumption.
