Recently, problem of earth environment being attended with international issue, people are concerned about the environmentally-friendly and renewable biomass energy. Especially, the forest biomass is more important because Korea have to control carbon footprint for Kyoto Protocol and Convention on Climate Change. In case of Korea, forest area covers the land about 2/3 of all country. It is needed that more economical and efficient method to estimate the biomass by remote sensing data which include wide coverage and is progressed by one-step. In this study, we estimate forest biomass with LiDAR data and aerial photograph. Three biomass equation is used and estimate mean biomass of single tree and entire biomass in plots. The results are compared with field data. $R^2$ of the mean biomass of single tree is greater than 0.8 and that of entire biomass in plots is greater than 0.65. In conclusion, the method using remote sensing data is verified more economical and efficient than previous field data method.

Transportation is gradually changing into the era of V2X and autonomous cars. Accurate judgement of traffic conditions is an important indicator of route choice or autonomous driving. There are many ways to use probes car such as taxis, as a way to identify accurate traffic conditions. These methods may vary depending on the characteristics of the probe vehicle, and there is a problem with the cost. The V2X vehicle can solve these problems and collect traffic information in real time. If all vehicles are of V2X vehicle, these issues are expected to be resolved briefly. However, if the communication information of a V2X vehicle is represented by a traffic representative in a traffic with only V2X, the traffic information of some V2X vehicles will be able to collect traffic information. To accomplish this, a virtual network and transport were created and various scenarios were performed through SUMO simulations. It has been analyzed that 3-5 % of V2 vehicles are capable of representative the road traffic characteristics. In the future, various follow-up studies are planned.

Despite the growing numbers of regional problems (e.g. conflicts between the state and localities, inter-local conflicts, etc.) associated with the state-led developmental projects, the Korean social sciences have been unable to offer satisfying explanations and solutions to the regional problems. This is mainly because the existing works, which have been taken captured by the assumptions of "methodological nationalism", significantly lack the socio-spatial understandings of the state actions and the relations between the state and localities, thereby seeing the issues of regional development mainly in terms of either the economic efficiency defined at the national scale, or the plan rationality of the national bureaucrats. With this problem orientation in mind, this paper aims to explore the ways in which the state and localities are interacting, conflicting and negotiating with one another through the mediation of the state-led developmental projects. Focusing on the developmental processes of Masan Export Processing Zone from the mid-1960s to the early 1970s, it examines the multi-scalar processes through which the state-led industrial complex developmental processes have been influenced by the complex and dynamic interactions among social forces and actors acting at diverse geographical scales (e.g. the global, national, local, urban, etc.). This analysis shows that the regional policies of the Korean developmental state were more heavily influenced by the interactions, contestations, and collaborations among social forces and actors, acting in and through the state, at various geographical scales, rather than by the economic and techno-bureaucratic rationality.

This study aimed to gauge the public awareness of the cultural value and superiority of Korean traditional sweets. Furthermore, it evaluated the obstacles that the Korean traditional sweet industry faces in the modern society, and a method to popularize it. It also analyzed the awareness of Korean traditional sweets. Both male and female study subjects showed the highest awareness of yakgwa and the lowest of chasugwa. Female respondents showed significantly (p<0.05~p<0.001) higher awareness of Osaekdasik, Hukimjadasik, Bellflower-junggwa, and Genseng-junggwa than male respondents. Maejakgwa, Osaekdasik, Rice-dasik, and Hukimjada- sik showed significant difference in awareness by the area survey respondents originated. Contrarily, Walnut-gangjung had significantly (p<0.001) higher awareness in rural areas than in more urban areas (e.g., large cities and small and medium-sized cities). Both male and female respondents answered (OR indicated) that the obstacles facing the Korean traditional sweet industry are uncommon products and expensive price. Both male and female respondents said that they had Korean traditional sweets less because it was harder to purchase than western sweets (due to limited access to these sweets), less delicious, and too expensive. Both male and female respondenst suggested that the urgent tasks to popularize the Korean traditional sweets were diversification in shape and ingredient, developing various new flavors, and cheaper products. Both male and female respondents responded that product diversification and strengthened marketing were urgent tasks to industrialize Korean traditional sweets. Therefore, it was believed that failure in generalization was the urgent problem of the Korean traditional sweet industry, and that Korean traditional sweets were harder to purchase because of lower accessibility than western sweets. To popularize Korean traditional sweets, it may be necessary to develop sweets in various shapes and ingredients, flavors suiTable to modern people, become cheaper in price, and have fancier (OR better) packaging.

Purpose: This study was conducted to investigate physical health status. depression. activities of daily living (ADL & IADL) of the low-income elderly who live alone in urban areas. Method: The subjects were the 400 low-income elders who live alone in Daegu city and the following instruments were used: 1. The number of self-reported physical health problems and present diseases: 2. CES-D scale for depression by Jo Nam-Oak et al. (1998): and 3. ADL scale by Katz (1989) and IADL scale by Lawton and Brody (1969). Results: 1. Visual difficulty was the most prevailing problem (55.3%) among physical problems. the second bowel elimination and the third hearing disturbance. As for present diseases. arthritis (26.5%), hypertension(24.3%) and DM (11.8%) were the most common diseases. 2. There were significant differences in physical health status according to age (t=3.115. p=.045). kind of medical security (t=-1.973. p=.049). perceived life satisfaction (F=4.966. p=.007) and the number of present diseases (F=2.937. p=.033). 3. There were significant differences in depression according to sex (t=-3.758. p=.000) . kind of medical security (t=-4.368. p=.000). perceived life satisfaction (F=35.743. p=.000) and the number of present diseases (F=4.246. p=.006). 4. There were significant differences in ADL according to sex (t=-2.136. p=.033) and age (F=4.863. p=.008). and in IADL according to sex (t=4.552, p=.000), age (F=3.090. p=.047) and kind of medical security (t=-3.306. p=.001). 5. Physical health state was correlated positively with both the number of present diseases (r=.140. p=.005) and depression (r=.352. p=.000), and negatively with ADL (r=-.176. p= .000) and IADL (r= -.230. p=.000). Depression was correlated positively with the number of present diseases (r=.169. p=.001) and negatively with both ADL (r=-.139. p=.005) and IADL (r=-.203. p= .000). Conclusion: The results of this study suggest that general characteristics are important factors for physical health status, depression. ADL and IADL of the low-income elderly who live alone and there are close relations among physical health status, the number of diseases, depression, ADL and IADL. Therefore, these results must be reflected in community health programs for the low-income elderly who live alone. In addition, this kind of study must be extended to the low-income elderly who live alone in rural areas.

With the increase of using pesticides, pesticide poisonings become more frequent. In the previous epidemiological study on pesticide poisoning and the reports of the authorities concerned, it is carefully affirmed that pesticide poisonings are caused by farmers' ignorance and negligence in using the pesticides. But the pesticide poisoning should be taken into account in terms of the person who sprays the pesticides, its spraying process, farming style and farmers' socio-economic conditions. And based on the understanding mentioned above, preventive measures for pesticide poisoning should be established. In this socio-medical point of view, this study examined the public health problems caused by using pesticides and the treatment of pesticide poisoning, based on the interviews with farmers in a area of Kyunggi-Do about the spraying process of pesticides, poisoning experiences and its treatments. The results are as follows ; 1) The style of spraying pesticides in the target area is mostly an individual one, not cooperative one. And the subjects of spraying are householders, whose educational backgrounds are beneath notice. More than 2~5 of the subjects are women or old men of 60 years old or so. These are seen to derive from the socio-economic status of Korean agricultural families; their younger generation's moving to greater cities and their petty farming styles. 2) As for the safety measures for the spraying of pesticides, those which have nothing to do with the economic, problems such as efficient spraying and productivity, are well obeyed. On the other hand, some safety measures as the use of safety devices, and spraying time, the degree of dilution of pesticides and the spraying method In windy days, are not obeyed very well, for to keep those makes spraying difficult to do and productivity worse. These facts indicate that the safety measures for using pesticides must be directly concerned with the spraying process, farming style and farmers' socio economic status, rather than the subject's knowledge or carefulness. 3) Even In cases of poisoning they do rarely consult the doctors. This is caused by the problem of their locality and transportation since one should pass away a day even in the busiest season to consult doctors, and by their low socio-economic status. 4) The epidemiological studies on pesticide poisonings should be necessarily led to a socio-medical one which are concerned together with the spraying process of pesticides, farming style, farmer's socio-economic status and discrepancies in public health policies between agricultural communities and urban ones.

Purpose: This study was undertaken to compare perceived stress and coping patterns, and their effects on depression between cancer patients and healthy adults. Methods: A descriptive design was used with 278 subjects, consisting of 139 cancer patients and 139 health adults, living in an urban area. All participants completed the following prerequisites; Stress Visual Analog Scale, Ways of Coping Checklist (W.C.C.L), Depression Index (CES-D), and Demography and Disease Data Questionnaire. Results: Perceived stress and depression were significantly higher, while wishful thinking was lower among cancer patients than healthy adults, after adjusting for education and family income which were not homogeneous between the groups. Among cancer patients, 20.2% of depression was mainly due to seeking support (10.7%), perceived stress and education, while 30.7% of depression in healthy adults was due to perceived stress, problem solving, and seeking support. Conclusion: These findings suggest that interventions to manage depression in cancer patients should include strategies to best foster positive coping patterns and reduce perceived stress.

The noise problem is one of the major problems associated with large cities and is considered important factor not only in maintenance but also in development of cities. Accordingly, the noise map is being increasingly used in city planning and design. However, the existing two-dimensional noise maps only show regional, planar distribution of noise. This study presented a method to build a data model for analyzing and visualizing noise levels at fine scale considering the vertical distribution of noise in a building. By expanding the 2D topology concept used in conventional GIS to 3D, it suggested a 3D GIS data model that makes 3D spatial queries, analyses and visualization possible and applied the proposed approach to building a 3D noise information system. By building and testing the system, the study showed different functionalities including 3D spatial queries and 3D visualization of noise levels varying temporally or according as the height of sound-proof walls. In each case, the population exposed to noise was quantitatively computed to illustrate the potential in the areas of city planning and design.

With the rapidly increasing population density and development of infrastructure, the loss of life and property damage caused by landslides has increased gradually in urban area. Especially, Because Busan has high percentage of mountainous terrain among the metropolitan in Korea, it is unavoidable to develop mountainous region excessively. The objective of this evaluation is to study on landslide hazard possibility for Mt. Hwangryeong in Busan Metropolitan City using the infinite slope model considering the groundwater level. All data related to creating the thematic maps was carried out using ArcGIS 10.0. The results show that FS (Factor of Safety) for landslide is inversely proportional to groundwater level change as expected. Most area indicates stable state in dry condition, and unstable area increase due to high pore water pressure when the groundwater level rise. However, several places in high lineament density area where landslide has been previously occurred, are more stable than other places according to the analysis. This inconsistency between real situation and analysis results indicates that additional analytical method would be necessary to solve the problem. Therefore, we suggest that development of new infiltration theory for unsaturated zone would be helpful to evaluate groundwater level distribution as time goes by.

Recently, our company has entered the modern knowledge company, government policy and regulation has a big influence on people's lives. Also, unlike in the past, I am hoping for administrative intervention as a problem peculiar to the environment, such as environmental housing problems, urban transportation problems, misuse problems, etc. and corporate pending issues. In this study, through the 10th year of the Seoul Special Citizen Judicial Police Force, if the local autonomy is a special envoy, it will try to present the correctness in the organization luck. As a measure to secure the nature of administrative action, the method of investigation was through the study of the execution process of administrative penalty and its result based on the statistical data of Seoul City. Therefore, we will analyze the process and operation of the 10-year organizational change of the Seoul Metropolitan Government's police force and examine how the police force of the people's livelihoods, which is a special investigation organization, is expanding its duties in order to strengthen the enforcement power of the administration. Also, we will make future-oriented suggestions to encourage the readjustment of the current relevant laws, such as the Ministry of Patriots and Veterans Affairs, and to actively accommodate the expected changes of the special law police organization in charge of the enforcement of the police system.
