The main purpose of this study is to analyze the differences of accompanying with environment interpreter in the ecological parks, and providing fundamental knowlege on the effective management method of the ecological parks by reviewing the effects of accompanying environmental parks in the ecological parks. We had done a field experimental design in the Gil-Dong ecological park, and evaluated the differences in the education effects, used types and satisfaction by the educational types - one is control groups, i.e., accompanying without environment interpreter and the other is treatment groups, ie., accompanying with environment interpreter through questionnaire survey and observation survey. The results of study are as follows; 1) In the respect of the effect of knowledge conveyance of the environmental interpreter, there appears higher educational effects of environment and ecology to the visitors of Gil-dong ecological park with an environment interpreter. 2) Accompanying with environment interpreter made the visitors reduce the depreciative behavior but no difference at environmental attitude and satisfaction. This results provide us the effectiveness of the environment interpreters. And more theoretical study is required in the future research.

The purpose of this study was that verify the difference of pro-environmental behavior according to be present or not of experience environmental education for developing pro-environmental and show basic material to prepare efficient operation plans of experience environmental education is based on factor which effect of pro-environmental behavior difference according to the types. Elementary schools were divided through existence and nonexistence of an experience environmental education than I was checked up the pro-environmental behavior of students, who joined in different environmental educations each other. It was analysis by dividing into an environmental education of school, an educator (teacher, environmental-interpreter), and fields for environmental education (school inside and outside) to know types of experience environmental education. In result, elementary schoolers who experienced an experience environmental education at school class, had higher an environment-friendly behavior and elementary schoolers, who experienced an experience environmental education at class from environmental-interpreter, had higher an environment-friendly behavior by and large. As a result, this study showed that the area based on their residential quarter and an experience environmental education with realistic plans to connect with social environmental education for developing pro-environmental carrying out the most positive effect.

Hanwoo is an important livestock resource in Korea. Its genetic improvements of economic traits have mainly focused on the steers in the past. However, there is a great necessity to extend the breed improvement programs to the cows as well. Therefore, the objective of this study was to investigate the effects of various environmental factors (person taking the measurement, region, year of measurement, month of measurement, image interpreter, birth-year and birth-year) on ultrasound measured carcass traits. A total of 27,215 ultrasound measurements of carcass traits were recorded between 2004 and 2012 for 22,620 cows born from 1997 to 2011. The ultrasound measures included backfat thickness (BFT), eye muscle area (EMA), and marbling score (MAR). The mean values for the BFT, EMA and MAR were 4.46 mm, $56.24cm^2$, and 4.12 point, respectively. Seven environmental factors, person taking the measurement, region, year of measurement, month of measurement, image interpreter, birth-year and birth-month, were tested to determine if they had a significant effect on the studied traits using the GLM procedure in SAS. All factors were found to significantly affect all the ultrasound carcass traits in this study. Unlike in previous studies, among the environmental effects, the significant effect of the image interpreter on the ultrasound carcass traits was shown for the first time in this study. These results indicate that future genetic evaluations of ultrasound carcass traits of Hanwoo cows should include all of the above environmental factors as well as the effect from people taking the measurements.

The purpose of this study is to propose remedial devices through the analysis on the operation status of nature trails in the nine National Parks in Korea. To accomplish these goals, the field survey for the nature trail facilities and their nature environmental conditions and a questionnaire survey also had been done, and 1,102 samples have been collected. Nature trails are usually located where the visitors re concentrated for a certain season or year-round, and ease of the visits guaranteed. However, since most of trails are located along the valley, the courses have disadvantage of passing in a single trail. Also, many trails are using former tracking courses, and the environmental conditions are not satisfactory due to the damages incurred by the visitors. Since nature trails are still on the introductory stage, basic tactics such as the design of courses, construction methods, management skills needs further improvements. As the Natural Parks Act does not have any clear definition of nature trails, it invokes the definition of tracking course instead, which in turn hinders the development of the nature trails. The nature trail system was just introduced to Korean National Parks and a pioneer in the Korea. Therefore, when provincial and urban recreational parks wish to introduce the environmental education programs within each park system, nature trails in national parks can be performed as a role model. Further improvements should be made within the such fields as preliminary natural ecological survey, lacks of professional designers for the facilities, lacks of interpreter and interpretation within nature trails.

The research carried out to analyze the change of recognition of elementary school students after a forest experience to determine the effectiveness of the environmental education in elementary school curriculum. The data is collected through surveys before and after forest experience for 311 people on 2nd and 3rd grades of two elementary school in Jeonju city, then the conclusions analyzed the results of the surveys are as follows. Students who participated in the forest experience show a positive change in all areas after the forest experience, for example, awareness of the forest and behavior recognition in the forest, the need for commentary about the forest. Especially, the area of the behavior recognition has much significant result than the other areas. In the details of the behavior recognition, a behavior recognition and environmental awareness for the life of the forest have been greatly improved. From the results described above, the forest experience can be seen a great help to elementary school students to have a respect and dignity of life and recognize the importance of the natural environment. Thus, the nature experience such as the forest experience is needed to enhance the life respect and environmental consciousness, foster sensitivity to natural cycles. In order that much more elementary school student can participate in evironmetal education through the forest experience, it would suggest to perform the forest experience as creative and experiential activities in the school curriculum.

This study aims to establish basic data of operating status for ecological learning facilities in Korea, investigate their characteristics for operating methods, and present proposals for the efficient operation and management of ecological learning facilities. For this purpose, a list of ecological learning facilities in Korea was established and 50 facilities were surveyed about the current status regarding the operation and management. Based on the survey, operation form, interpreter and volunteer, visitor, budget and revenue, promotion method, and other items were analyzed. Concerning the operating forms, most of the facilities were direct-operated facilities by government, and they are operating mainly by officials. Visitors are mostly families on weekends, while kindergarten children are main visitors during weekdays. Most facilities have higher proportion of visitors nationwide, and they get information mainly from websites operated by facilities and related organization. The annual operating budget and revenue depend on the facility size and operating forms, and the direct-operated facilities by government use higher budget compared to commission-operated ones. For the efficient operation of ecological learning, expert with specialized knowledge should participate in the operation, and intuitive and informative websites should be established and continually managed. In addition, it is necessary to support revenue of by national and local governments and to secure external funding network like local companies and donation.

The goal of the study is to provide basic information that can be used to come up with environmental interpretation methods that are appropriate to the conditions of urban parks. For this matter, research was conducted to find out whether the environmental interpretation that was provided to the visitors of the World Cup Park Visitor Center encouraged them to become interested in the environment and to understand how such environmental interest was related to the level of satisfaction that the visitors were experiencing from their visits to the park. At the same time, the research was designed to find out whether the park's visitors were affected differently in terms of their environmental interests and their experience depending on the two different types of environmental interpretations; Interpreter's Interpretation and Self-guiding Interpretation. Experimental result showed no statistically meaningful correlation between environmental interpretation and environmental knowledge, though the experimental group subjected to environmental interpretation was found to have higher environmental knowledge than that of the control group, which was not subjected to environmental interpretation. As for the correlation between environmental knowledge, which was acquired through environmental interpretation, and environmental interest, the group, which showed big changes in terms of the volume of environmental knowledge, was found to have higher environmental interest than that of the group, which recorded a low level of changes in the volume of environmental knowledge. Also, the difference in their level of environmental interest was big enough to be acknowledged statistically. Also environmental interest, which was created thanks to environmental interpretation, was found to affect the level of satisfaction visitors feel when visiting the park. Even though the study was intended to find out how environmental interpretation affects park visitors by means of analysis that can be proved based on facts, it was difficult to control some of the variables due to the circumstances under which the experiments were conducted. Despite this, the study can be considered meaningful in the fact that the researches and experiments were conducted at a park that is actually visited by people. It is also believed that as one of the first studies done on the World Cup Park, it could serve as a basis upon which future studies could be carried out.

It was already realized at a current technological level of home network systems that the systems recognizes a user's simple order and carry out the order in the ubiquitous computing environment. However home is not a simple environment consisting into a large number of family members, so various order and situation would be needed accordingly. From now on we need to reach the technological level to infer that how is the user's behavior patterns and what kinds of service is the fittest to user who belong to the ubiquitous computing environment by using the result of the context interpreter. In this regards, active inferred-model needs to be suggested upgrading user's command into one step more higher level than the simple one adapting diversified feature. This study would like to suggest this active model recognizing context, which is user's environmental information applying basic network and inferring Context-based Service that user wants through the recognized result This study proposes a new method that can infer the user's desire in ubiquitous computing environment. First of all, we define a context as user's information of ubiquitous computing environment situation that user belongs to and we classify the context into 4W1H(Where, Who, When, What) formats. We construct Bayesian network and put the factor of context use as Bayesian network nodes. As a result, we can infer the user's behavior pattern and most proper service for user in the intelligent space from the probabilistic result of Bayesian network.

It is usually very expensive and often impractical to extend a load test on a large pile until collapse. Many graphical or mathematical methods have been attempted to estimate the bearing capacity from the results of a vertical load test without having to load the pile to failure. According to Fellenius, the failure value must be based on some mathematical rule and generate a repeatable value that is independent of scale relations and the opinions of the individual interpreter. This study presents the method which may estimate the failure load using the maximum curvature to apply Kondner's theory from the results of a loading test which cannot be extended until the failure load is reached.
