Recently, information-oriented whole domain and scientific management method for nation-wide territory is widly being used due to the remarkable development such as GIS and RS. In addition to this, request for analyzing forest spatial information has been increasing to manage forest resources efficiently. Although forest information using satellite image and GIS has been built to analyze a large amount of forest information scientifically, there are many difficulties to gather information because normally forest area is large and difficult to access.. This research uses high resolution satellite and digital aerial photograph around Kyungju city area to classify forest area, and stratifies forest area through a spot survey and a comparison of sample area. It will be possible for us to draw a more detailed map of forest area than 1/25000 map of forest area through these works.

Recently, DMB service markets experience a rapid change with terrestrial DMB test-broadcasting for the nation-wide coverage and paid interactive data broadcasting being offered utilizing TPEG and BIFS technologies. This warrants a reexamination of a consumers' adoption intentions for DMB service. This paper uses a survey data set to analyze DMB adoption intentions and the choice between terrestrial DMB and satellite DMB services according to preferred contents and other media usage characteristics. Empirical results show that consumer who prefer TV, music, and movie contents are more likely to adopt DMB service, whereas consumers with high intentions for HSDPA subscription are less likely to adopt DMB service. This implies that continuing development of killer application and the analysis of substitutes or complements of other media are crucial for the increase of DMB adoption intentions. It is found that the more consumers prefer sports, movies and entertainment/game and put higher values in the quality of the contents, the more likely they adopt satellite DMB service. Meanwhile, the more consumers prefer TV, drama and news contents, and are sensitive to the subscription fees, they are more likely to adopt terrestrial DMB service. Therefore, it seem that consumers' DMB adoption between terrestrial and satellite services is crucially related with types and characteristics of contents offered.

Objectives: This study aims to identify the factors associated with colorectal cancer screening behaviors. Methods: The nation-wide representative samples of 2,928 adults aged ${\geq}50$ years for colorectal cancer screening were derived from the fourth Korea National Health and Nutrition Examination Survey (KNHANES IV). This study investigated socio-demographic, health behavioral and contextual factors associated with colorectal cancer screening using descriptive statistics and multivariate logistic regression analysis. Results: In terms of socio-demographic factors, gender, age, marital status, occupation, monthly income, and resident region were significantly different between screening group and non-screening group. Among health behavioral and contextual factors, regular physical checkup, weight control, physical activity, smoking, drinking and having other cancers were significantly different. From the multivariate logistic regression analysis, marital status, education level, regular physical checkup and weight control were associated with colorectal cancer screening behavior. Conclusions: It is necessary to understand the importance of early detection and cancer screening. Appropriate health education and active promotion about the cancer screening should be developed based on the study findings in order to motivate people to have cancer screening. Also, these findings should be reflected in the health policy.

Cool roofs are currently being emerged as one of important mechanism to save energy in relation to the building. Although green roof has already gained nation-wide recognition as a typical method of energy saving in the roof, this approach did not provide a realistic evidence that is economically feasible in terms of installation cost. This research is primarily intended to compare installation cost between the two techniques. This research proposes a comparative evaluation framework in a more objective and quantitative way for an installation cost between the two techniques. Kyungpook National University (KNU) was selected as a survey objective and an exhaustive and realistic comparison of installation cost between the two techniques was conducted, based on Life Cycle Cost analysis (initial investment cost, maintenance cost, dismantling and waste disposal expense). It was possible to identify that installation cost of cool roofs is 4.7 times cheaper than that of green roof. Also present value based on probabilistic approach was identified as 0.25 (4.95) higher than the installation cost on the assumption of constant price and interest. It is expected that much more installation cost for the large scale green roof will be required since small-size green roof selected as a survey objective in this study could be operated under less initial installation and maintenance condition.

The purposes of this study were to suggest the methodology to select prior areas in the environmental pollution survey for livestock excreta (EPSLE) as well as to elucidate the validity of the methodology. In this study, the prior areas in the EPSLE were determined by examining the number of compost facilities categorized according to the three levels of size including the basin, the sub-basin and the watershed, respectively, based on the data from "Annual Nation-wide Pollution Sources Survey (2012)". The results suggested that the list of prior basins were Nakdong, Geum, Youngsan and Han river basins in order. Also, it was examined that the prior sub-basins in the four river basins including Nakdong, Geum, Youngsan and Han rivers were Naesung Stream, Geumgang Gongju, Juam Dam and Namhan Downstream, respectively. The prior watersheds in the sub-basins of Naesung stream, Geumgang Gongju, Juam Dam and Namhan Downstream were Seocheon Downstream, Geum Stream, Gyeombaek Suwipyo and Yanghwa Stream, respectively. The validity of the methodology used in this study was elucidated by analyzing the correlation of the number of compost facilities with the concentrations of T-N and T-P observed in the end-points of sub-basins. The results of correlation analysis showed that the concentrations of T-N and T-P increased with the number of compost facilities. Specifically, there was the stronger correlation between the number of compost facilities and the concentrations of T-N than that for T-P. Consequently, it was proved that the methodology used in this work was valid and rational for the selection of prior areas in environmental pollution survey for EPSLE.

Recommendaton: These are the highlights of the findings of the Timber Consumption Survey carried out by the Project in 1966, and covering consumption for the period from 1961 to 1965. The survey was oriented towards consumption for structural, commercial and industrial purposes and existing estimates for local (village-level) consumption as fuel and the like were adopted. A full report on the survey was submitted to the Bureau of Forestry in 1966. Long-term Trends: After allowance for anticipated population increase, this ten year's increase in industrial wood consumption represents a gain of about 30% in per capita consumption (from 0.0913 cu.m. per capita to 0.118 cu.m. per capita). This is only about half the expected general economic growth of about 75% (7% per annum). It is therefore likely (a) that the 1975 estimate is conservative, (b) that the consumption demand beyond 1975 may be expected to build up at a greatly increased rate. Estimated income elasticity coefficients are high, and with expected ir,creases in prosperity and population, the consumption is expected to rise to 10 million cu. meters by the year 2,000. Consumption Pattern: The breakdown of industrial consumption (1965) is given in Table 4-2, showing sawnwood consumption as the most important in 1965. The upward trend in all sectors over the 1961-65 period is expected to continue. The general consumption pattern is expected to change through 1975 with a sharp increase in the relative importance of pulp products (to 30% of total consumption) offset by declining relative importance of sawlogs. The following recommendations follow from the study: (i) Industrial forests. - A programme of establishment of consolidated industrial forests should be initiated as a matter of urgency. (ii) Fuelwood forests - Properly sited, protected and managed fuelwood forest, worked on a 20-year rotation, should be established as a nation wide basis. (iii) Hardwood utilization - Detailed investigations are required into the use of indigenous hardwoods for the pulp, particle board and hardboard industries. (iv) Mining timber - Preservation treatment of all mining timber should be enforced by law. (v) Sawmills - Licencing restrictions should be enforced to reduce the number of small, inefficient sawmills. b. Extension work should be undertaken bv government to improve sawmilling practices.

최근에 들어 정부차원에서 GIS 활성화를 위한 전반적인 계획을 완성하였고 그 계획 중 가장 큰 비중을 차지하고 많은 파급효과를 가져올 국가기본도 전산화를 이미 시작하였다. 많은 예산을 들여서 만들어질 데이타가 전통적인 지도제작을 목적으로 구축되기보다는 앞으로의 많은 응용분야에서 활용할 수 있는 데이타가 입력 당시부터 고려되는 것이 바람직하기에 수치지도제작(Automated Mapping)만을 위한 데이타모델과 다양한 응용을 수용할 수 있는 데이타 모델의 차이점을 분석하고 외국 국립지리원들의 데이타 구축사양을 비교해 봄으로 국가기본도 데이타베이스의 구축모델의 방향을 제시하였다. 우리의 실정에 맞는 모델의 설정을 위해 영국의 Ordnance Survey와 미국의 USGS의 데이타 구축모델을 분석하여 이상적 모델을 제시하고, 우리나라가 최근에 선택한 데이타 진환 표준안인 SDTS와 연계시켜 효율적으로 선진국 수준에 갈 수 있는 한국형 모델을 구상하였다. 이러한 모델의 구상은 우리나라 국립지리원의 지도제작 목적과 다양한 응용을 동시에 수용하기 위한 것이며 궁극적으로 한국의 실정에 맞는 모델이 구체화되는 계속적인 연구가 있어야 할 것이다.

Carbon monoxide poisoning is one of the most serious health hazards in Korea. Although the incidence rate has been assumed to be the highest in the world, there has been no avaiable reports as far as the annual & nation-wide incidence are concered. Authors analyzed the incidence reports from 1965 to 1970 filed by the National Police & also made incidence survey on Seoul area in 1968 & 1969. The results of these surveys informed us that the official police reports are very much underevaluated. The stochastic estimations of the generel incidence were made based on the informations which were obtained through incidence survey made in Seoul area. The findings obtained are as follows; 1. The annual incidence of CO poisoning tends to increase since 1965. 2. The incidence is higher in the urban area & the incidence in Seoul is the highest in the world. 3. The frequency of incidence is the highest in the December. 4. The main causes of poisoning are the gas leakage from 'ondol' floor & the leaking of gas from kitchen to room through the connecting door. 5. The incidence survey made in Seoul area revealed that the official police reports are underevaluated around one-eighth of actual incidence. 6. The health hazards induced by CO poisoning is greater than those caused by 19 Class I & Class II communicable diseases.
