Analysis of fish farm influences on stream water quality may provide basic informations on watershed management to reduce environmental impact due to fish farm development and to conserve stream water quality in forested watershed area. In this research stream water qualities around Mt. Baegun area were monitored seasonally for three years. Due to the increase of pH in effluent water from the fish farm it was believed that alkalization of stream water can be accelerated by large scale development of fish farms in the forested watershed area. As a result of regression analyses, the linear equation of pH of influent and effluent water of fish farm was, pH of effluent water of fish farm = $0.6234{\times}pH$ of influent water of fish farm + 2.6263. Also, the linear equation of electrical conductivity of influent and effluent water of fish farm was electrical conductivity of effluent water of fish farm = $1.7275{\times}$electrical conductivity of influent water of fish farm - 14.007. Negative effects on stream water quality were observed by indications of increase in electrical conductivity and water temperature of effluent water from the fish farm. Decreases in physicochemical indices such as the amount of dissolved oxygen, total amount of cation and total amount of anion in effluent water from the fish farm were also negative aspects in downstream ecology. It is recommended that water purification system as well as environmentally-friendly fish farm design should be incorporated to large scale fish farm development plan in forested watershed area.

Quantifications of fish farm influences on stream water quality may provide basic informations on watershed management to reduce environmental impact due to fish farm development and to conserve stream water quality in forested watershed area. In this research stream water qualities around Mt. Paekun area were monitored seasonally and the following results were obtained. Due to the increase of pH in effluent water from the fish farm it was believed that alkalization of stream water can be accelerated by large scale development of fish farms in the forested watershed area. Negative effects on stream water quality were observed by indications of increase in electrical conductivity and temperature of effluent water from the fish farm. Decreases in physicochemical indices such as the amount of dissolved oxygen, percentage of dissolved oxygen, total amount of cation, total amount of anion and total amount of ion in effluent water from the fish farm were also negative aspects in downstream ecology. It is recommended that water purification system as well as eco-friendly fish farm design should be incorporated to large scale fish farm development plan in forested watershed area.

일본(日本)에서 계류변(溪流邊)의 환경복원(環境復元) 발전전략(發展戰略)(V) -한국적(韓國的) 적용(適用)을 중심(中心)으로-

The objective of this study was to introduce the current status and development strategy for the environmental restoration of stream side in Japan, and to consider the methodology which could be effectively applied to the environmental restoration of stream side in Korea. 1. We should establish a new paradigm of forest conservation and erosion control which can emphasize the restoration of the stream side ecosystem and reduce soil movement in the areas. Also, in the past, the objective of forest conservation and erosion control was to fix soil by constructing permanent structures. The direction of future forest conservation and erosion control needs to be new forest conservation and erosion control technology to prevent large scale soil movement but allow small scale soil movement to conserve sound ecosystem and biotic habitats. 2. In the past, the goal of forest conservation and erosion control planning was to fix the amount of soil movement by constructing permanent facilities. Forest conservation and erosion control planning in the future needs to change the techniques which could prevent soil movement from large scale of soil disasters, but allow soil movement effectively to a small and middle scale's soil movement. Also, it is considered to change erosion control dams from non passing type to passing type. 3. In the point of ecological conservation aspects, we should evaluate the effects of new forest conservation and erosion control methods which are emphasized on the restoration of the stream side ecosystem. Also, forest conservation and erosion control construction projects for restoring stream and river ecosystem should be planned for perfectly restorating their ecosystems by the way of sustainable maintenance and management. 4. The restoration direction of stream and river ecosystems needs to be restoring the diversity of small geographies such as waterway, shoal and puddles rather than flattening stream bed. And the restoration of the stream side ecosystem should provide continuity of the stream side environment which allows desirable biological habitats, and environmentally sound facilities to harmonize with the environment.

우리나라 37개 땅밀림지의 지질 및 토양 특성

This study was conducted to provide basic data for classifying patterns of land creep in 37 areas in South Korea using geological and soil property analyses. Geological time, as it relates to land creep areas in South Korea, had been most impactful for the Gyeongsang Supergroup and its sedimentary bedrock during the Cretaceous period. In this area, perfect ridge cliffs in land creeping areas included 20 plots (approximately 54.0%), while tension cracking areas with ambiguous ridge cliff characteristics included 17 plots (approximately 46.0%). Hesitant slide slope types included 20 plots (approximately 54.0%) within theslide slope of an incident pattern (slide slope figure) in land creeping areas. Colluvial debris types among land creep patterns were the most frequent and included 25 plots (approximately 68.0%). The direct causes of land creep were cutting of foothills, quarrying, land-clearing in mountains, mining exploration, and the creation of burial grounds, all of which added to geological impacts. Among land creeping areas, 27 plots (approximately 73.0%) were the result of man-made activities, and 10 plots (approximately 27.0%) were derived via natural causes such as earthquakes, heavy rainfall, and caving. 이 연구는 우리나라에서 발생된 전국 37개소의 땅밀림지의 지질 및 토양특성을 분석하여 땅밀림지에 대한 유형을구분하기 위한 기초자료를 제공하기 위하여 실시하였다. 땅밀림지의 지질 시대는 백악기가 가장 많았으며, 경상누층군에서가장 많이 발생하였다. 주된 구성암석은 퇴적암이 가장 많았다. 또한 땅밀림지 중 활락애가 명확하게 구분된 지역은 20개소(약 54.0%), 활락애가 모호하고 인장균열(균열)이 발생한 지역은 17개소(약 46.0%)이었다. 땅밀림지의 발생 형태(붕괴면의 형상)는 주저형 붕괴면이 20개소(약 54.0%)로 가장 많았다. 땅밀림 발생유형은 붕적토 땅밀림지가 25개소(약 68.0%)로가장 많았다. 땅밀림의 직접적인 원인은 지질적인 원인에 더해 산각절취, 토석 및 토사채취, 산지개간 및 절취, 광산개발, 묘지조성 등 인위적인 개발사업에 근거하는 것으로 나타났다. 전국 37개소의 땅밀림지 중 인위적인 원인에 의한 땅밀림지는 27개소(약 73.0%)이었으며, 지진, 집중호우, 하천포락 등 자연적인 원인은 10개소(약 27.0%)이었다.

최근 사용자 경험(User experience)에 대한 관심이 고조되면서, 제품/서비스의 사용자 경험을 어떻게 증대시킬 것인가에 대한 학문적, 실무적 접근이 시작되고 있다. 이에 따라 사용자 경험의 정량화에 대한 필요성이 증대되었다. 본 연구에서는 HCI, 인간공학뿐만이 아니라 컴퓨터공학, 정보공학, 품질공학, 경영학, 마케팅 등 다양한 분야에서 사용된 정량화 방법들을 분석하여 체계적으로 정리하였다. 기존 문헌 분석 결과, 사용자 경험 정량화를 위해 고려해야 하는 세가지 측면, 즉 1) 사용자의 의사결정전략, 2) 구성요소들 간의 상관관계 및 인과관계, 3) 수학적 모델 별로 가능한 대안과 장단점을 도출하였다. 본 연구결과는 제품 및 서비스의 사용자 경험 지수 개발에 활용할 수 있을 것으로 기대된다.
