The purpose of this study is to survey the community support program of Green Belt from 2001 to 2011 and propose the improvement of the institution. For research method, the projects were analyzed by year, area, and category using statistical data. The improvement of the institution was drawn through the opinion survey of the interest group such as residents and public servants. For 10 years, 2007 community support projects were carried out and the total amount of government expenditure was 583.9 billion won. Among the support items, life convenience projects comprise 96.7%. For area, metropolitan area comprise 32.5%. There is a bias in items and areas. According to the survey of the residents and public servants, the satisfaction for the community support program is increasing. But it is necessary to enlarge the direct life cost support, activate community involvement and develop new project type. Proposed new projects are such as making characteristic village for income creation, planning for the landscape preservation using historic and traditional resources, making leisure space for nearby residents, and projects for the aged people. And it is proposed to give incentive to the characteristic village projects through competition.

Governments and related agencies have made efforts to introduce tree burials (TB) as an alternative to solve the problems involved in the traditional funeral manners. Citizens' TB selection rates are, however, still very low. It is important to understand citizens' perceptions and attitudes towards TB to make people more actively participate in TB. This study examined citizens' knowledge, behavioral belief, attitudes towards selecting TB, intentions to select TB, and their relationship with citizens' socio-demographic characteristics. A total of 320 citizens in Gwang-ju, Korea, completed the survey during May, 2011. Results showed that 65.3% of respondents were aware of TB, and many of them (47.6%) obtained information from TV/Radio. Age, education level, marital status and birth order were related with knowledge about TB. Respondents with higher age or higher education level tended to have higher knowledge rates. The married or the non-eldest sons also had higher knowledge rates. Respondents with higher age or higher education level, and the married tended to have more positive attitudes towards selecting TB and to rate 'unconventional funeral customs' high. Respondents with higher age, education level or married respondents tended to have higher intention to select TB. The knowledge level about TB was positively related with attitudes about TB selection and intention to select TB. The results were discussed and some ways to promote TB were suggested.

A survey showed that the public perception of the shipping industry's overall image and economic role was relatively positive. The survey revealed that public perception was mixed with respect to the multifaceted role of the shipping industry. Based on the results of this survey, this paper proposes three approaches to improving the public perception of the shipping industry. The organization contact approach includes establishing shipping institutes for city people, holding various events targeted at the public, establishing a shipping memorial hall, developing a shipping-related culture and tourism, reinventing the image of the shipping industry through a shipping-culture movement, and creating new views of the shipping industry by conducting formal education. The goods and services contact approach includes building a brand image for shipping services, providing B2C services, utilizing the national image for the shipping industry, and participating in international cooperation projects. The text contact approach includes B2B advertising, advertisements focused on the national economic and multifaceted role of the shipping industry, package advertisements for the shipping industry and related industries, the Internet and high-technology media, government-initiated PR activities regarding the multifaceted role of the shipping industry, and funding for advertising the shipping industry.

The purpose of this study is to investigate the changes in the accessibility of the Metropolitan Seoul Transit systems since 2000, in which many new subway lines have been constructed as well as other urban transit lines have been connected to the systems. We suggest an accessibility measure model for Un-fixed Transportation Networks. In order to measure the nodal accessibility based on the mobility, we apply path-distance, physical-distance, and time-distance as the distance impedance measurement. Specifically, we develop time-distance algorithms to measure the time-distance between each pairs of transit stations based on the T-card transaction databases. We apply the model to the Metropolitan Seoul Transit systems in two time points(2005 and 2011). We examine the results in terms of three distance accessibility measures. Time-distance accessibility explains better the urban land use patterns in the Metropolitan Seoul area than the other two. We visualize the spatial patterns of time-distance accessibility by applying GIS, and analyze the spatial structures of accessibility in the Metrropolitan Seoul area between two time points.

It is commonly estimated that there is a much higher potential for accidents at a crossroads than along a single road due to its plethora of conflicting points. According to the 2006 figures by the National Police Agency, the number of traffic accidents at crossroads is greatly increasing compared to that along single roads. Among others, crossroads installed with traffic signals have more varied influential factors for traffic accidents and leave much more room for improvement than ones without traffic signals; thus, it is expected that a noticeable effect could be achieved in safety if proper counter-measures against the hazards at a crossroads were taken together with an estimate of causes for accidents This research managed to develop models for accident forecasts and accident intensity by applying data on accident history and site inspection of crossroads, targeting four selected downtown crossroads installed with traffic signals. The research was done by roughly dividing the process into four stages: first, analyze the accident model examined before; second, select variables affecting traffic accidents; third, develop a model for traffic accident forecasting by using a statistics-based methodology; and fourth, carry out the verification process of the models.

To study the effects of soil moisture and texture on characteristics of growth, content of saikosaponins and activity of antioxidative enzymes in Bupleurum falcatum L., content of saikosaponins(a, c and d) and activities of superoxide dismutase(SOD) and peroxidase(POD) were investigated with two Bupleurum genotypes(Jangsoo and Samdo). Two Bupleurum genotypes were grown under different soil moisture(deficit, normal, surplus) and soil texture(sandy, sandy loam, loam) conditions. Among the tested soil conditions, dry weight accumulation rate of both cultivars could be ranked in the order surplus > normal > deficit soil for soil moisture and sandy > sandy loam > loam for soil texture. Under the surplus soil condition, growth retardation of Samdo cultivar was more severer than that of Jangsoo. Furthermore, content of saikosaponin a, d, and c also could be ranked in the order deficit > normal > surplus and sandy > sandy loam > loam for soil moisture and texture, respectively. Although both Jangsoo and Samdo cultivars grown under water deficit condition showed the highest POD and SOD activity, in general POD and SOD activity in both shoot and root was remarkably high in Jangsoo cultivar compared with Samdo. Saikosaponin content of root was positively correlated with POD and SOD. However, shoot and root length were negatively correlated with POD.

Asian gypsy moth, Lymantria dispar asiatica (Lepidoptera: Erebidae), which is an indigenous pest in Korea, a large outbreak has been reported in Gyeonggi-do, Chungcheong-do, and northern Gyeongsangbuk-do from 2019 in forest and nearby downtown areas, causing emotional damage to forests and city dwellers. During the indoor culture of gypsy moth eggs collected in Yecheon, Gyeongbuk in 2021 we found that 79.65% (321/403 of first instar larvae) were died due to Lymantria dispar multiple nucleopolyhedrovirus (LdMNPV) infection. Sequence analyses of 36 gypsy moths collected from 12 regions in Korea using LdMNPV late expression factor-8 (lef-8) and polyhedrin (polh) genes showed a genetic variation of 0.80% and 0.86%, respectively. Comparison to GenBank data showed that the Korean samples were most similar to LdMNPV in Japan, whereas most different to those of Turkey. These results showed a high infection rate of LdMNPV in Korea and LdMNPV is one of the important population regulators of the gypsy moth.

The Study aims at carrying out basic research on the future housing culture plan by the aging and low fertility phenomenon which is the most serious problem that Korean society faces today. In the future, the housing culture will be transformed into a 'convergence housing complex's residential culture' that can be coexisted with households with various members, rather than a housing type represented by apartments today, due to the phenomenon of nuclear family and the increase of one resident. In this regard, this study is a basic study on the housing complex culture of Korea. It is not that the hosing complex culture has been imported from the western society today, but the Korean traditional housing complex's culture proposed by Korean first developer Segwon Jeong has already existed in Korea urban and architectural perspective. In the early 20th century, Segwon's improved Hanok planned to complement the disadvantages of the existing hanok and the modernization of hanok such as the standardization of hanok, moreover the most important point is the beginning of the Korean style housing complex by modernization of the inner space of hanok. It is expected that this study for Segwon's housing complex of improved hanok will provide important basic data for the Korean-style convergence residential culture plan needed for our society in the future.

In this study, the mixed toxicity of heavy metals (Cu, Pb, Hg) and surfactants (SLS, ALS) was evaluated by using Vibrio fischeri and Daphnia magna. The sensitivity of ecotoxicity to heavy metals was sensitive to daphnia but the case of surfactants were more sensitive to Vibrio fischeri. Experimental results of Vibrio fischeri show that the toxicity value P(O) was lower than the predicted value P(E), and the antagonistic effect was observed when the heavy metal and the surfactant were mixed. It seems that SLS and ALS, which are anionic surfactants, have anionic form on the hydrophilic head, so that they have an antagonistic effect that they are bonded with heavy metal ion which is a cation type and the actual toxicity is lowered. In Daphnia magna, the results showed that antagonistic, additive and synergistic effects were in order as concentrations increased. As the concentration increases, Daphnia magna, which is highly sensitive to heavy metals, seems to have a synergistic effect with a rapid increase in mortality.
