Objectives: The purpose of this study was to examine the oral health care of oral prophylaxis practice lab visitors, their recognition of oral care supplies, their use of oral care supplies by type, and influential factors for their recognition and use of oral care supplies. Methods: The subjects in this study were 275 people who visited an oral prophylaxis practice lab at a university located in an urban community. The visitors were respectively interviewed from March to June, 2016, and the data from 260 respondents who properly responded were analyzed, and data from 15 visitors who provided incomplete responsees were excluded. Statistical analysis was performed using the nonparametric tests, mann-whitney test and kruskal-wallis test, and multiple regression analysis using SPSS. Results: The mean score of oral care products was 2.25, the average degree of use was 0.09, and dental floss (0.29) was the most used oral care product. There was a significant difference between the groups according to gender (p<0.001), age (p<0.001) and marital status (p<0.001). Factors influencing the perception of oral care products were experience in brushing education and experience in oral care products education. Conclusions: The recognition of the oral prophylaxis practice lab visitors about oral care supplies and their use of the supplies were under the influence of oral health education. Therefore, sustained efforts should be directed into the development of efficient oral health care education programs that can inform people about the importance of oral health care, publicize oral care supplies, and encourage the use of these supplies.

Water quality in Lake Rotorua, New Zealand, deteriorated since the 1960s because of excessive phytoplankton growths due principally to increasing nitrogen and phosphorus in the lake waters. Nutrient concentrations in eight of the nine major streams feeding Lake Rotorua have increased since 1965. The groundwater system has a key role in the hydrology of the Lake Rotorua catchment and the groundwater system is probably the control on the time delay between intensification of agricultural land use and response of surface water quality. All major, and many minor streams, in the catchment are fed by springs. Two lithological units are most important to groundwater flow in the Lake Rotorua catchment: Mamaku Ignimbrite, erupted in about 200,000 years ago and Huka Formation sediments which filled the caldera left by the Mamaku Ignimbrite eruption. Rainfall recharge to groundwater in the groundwater catchment of Lake Rotorua is estimated as approximately 17300 L/s. A calibrated steady-state groundwater flow model estimates that approximately 11100 L/s of this flow discharges into streams and then into the lake and the balance travels directly to Lake Rotorua as groundwater discharge through the lake bed. Land use has impacted on groundwater quality. Median Total Nitrogen (TN) values for shallow groundwater sites are highest for the dairy land use (5.965 mg/L). Median TN values are also relatively high for shallow sites with urban-road and cropping land uses (4.710 and 3.620 mg/L, respectively). Median TN values for all other uses are in the 1.4 to 1.5 mg/L range. Policy development for Lake Rotorua includes defining regional policies on water and land management and setting an action plan for Lake Rotorua restoration. Aims in the action plan include: definition of the current nutrient budget for Lake Rotorua, identification of nutrient reduction targets and identification of actions to achieve targets. Current actions to restore Lake Rotorua water quality include: treatment of Tikitere geothermal nitrogen inputs to Lake Rotorua, upgrade of Rotorua City sewage plant, new sewage reticulation and alum dosing in selected streams to remove phosphorus.

Korean societies have been experiencing the wholesale structural changes in the rapid currents of recent openness, globalization and democratization, which effect much more heavily in rural areas than in urban areas, so rural recomposition works being an important national concern. In order to systematically reconstruct the rural structure, the decision makers, with a four step hierarchy of rural resident-residents group-community-region, should be endowed with the objective judgement on basic elements of resource potentialities under their control. In this process. rational resource evaluation works would be firstly necessiated from expert groups. Based on the view mentioned above, this study principally aimed at developing a rational evaluation framework for rural resources. For that objective, the first step of the study pigeonholed the total resources items identifiable in rural areas from the existing study results, spatial planning and field surveying data. After then, using the formalized classification criteria of resources items, a tentative goal system for rural resources evaluation was proposed and the final one determined through expert-group checking. The results obtained during the study are summarized as follows ; 1. Using the existing examples of resources identification/classification and the basic data list for county-level development planning as the principal reference ones, total rural resources elements were classified into 3 constituent units : land, natural environment and human resources, which correspond to places to work, to play and to live, respectively, as 3 constituent ones of life-supporting space. 2. Three characteristic areal types were adopted to represent the total rural areas : lowland, upland and seashore areas, and also 3 practical use types to represent the objectives of resources evaluation systems : for land use planning, natural conservation policy and village improvement planning. Thus 9 different types of goal system for resources evaluation were developed(each system by 3 areal typesX3 practical use types) 3. Each goal system has 3-tier classification steps from the higher, middle and lower one. The higher and middle steps should contain equally applicable components to all the rural areas, of which allowable number being around 3 and 4 respectively. However the lower step would contain detailed sub-components changeable to areal characteristics of which allowable number being around 7.

Global warming is regarded as one of the most critical issues that should be taken care of by the entire global community as it threatens the survival of mankind. South Korea, in particular, undergoes faster warming than the average rate of global warming. South Korea has revealed various warming rates and trends being surrounded by sea on three sides and having complex terrains dominated by mountains. The rates vary according to regions and their urbanization and industrialization. Differences also derive from seasons and weather elements. Changes to the highest, mean, and lowest temperature are also different according to the characteristics of regions and observatories, which is more apparent where the force of artificial weather applies. In an urban area, temperature gaps tend to decrease as the lowest temperature rises more than the highest temperature. Meanwhile, temperature gaps grow further in a coastal or country region where the force of artificial weather is small and the force of natural weather prevails. In this study, the investigator analyzed the changes to the weather elements of 11 observation spots that had gone through no changes in terms of observation environment since 1961, were consecutively observed, and had the quality of their observation data monitored on an ongoing basis. Using the results, I tried to identify natural and artificial causes affecting certain spots. Located on the east coast of the Asian Continent, South Korea sees weather changing very dynamically. Having huge influences on our weather, China has achieved very rapid industrialization for the last 30 years and produced more and more greenhouse gases and air pollution due to large-size development projects. All those phenomena affect our weather system in significant ways. Global warming continues due to various reasons with regional change differences. Thus the analysis results of the study will hopefully serve as basic data of weather statistics with which to set up countermeasures against climate changes.

Background and objective: Problems currently occurred in the environment are caused by a lack of environmental awareness of the community. Biology students learn the environment in ecological learning. Students must explore environmental knowledge (EK) and are expected to have high environmental awareness (EA) and then apply their knowledge in daily life with pro-environmental behavior (PEB). There is a need for designing climate-change book serials for university students (CCBS-US) towards contextualized learning. This study aimed to determine the relationship between EK and EA and the PEB of biology students as a baseline for designing CCBS-US. Methods: The study used a quantitative descriptive method with a correlational design. Total 136 biology students from a state university in Jakarta, Indonesia served as samples of the study. Results: Research results revealed a positive relationship between EK and PEB of biology students. There was a positive relationship between EA and PEB of biology students and between EK and EA and PEB of Biology students. Moreover, 77% of students reported their EK is very high, 55% of students reported their EA is medium, and 46% of students reported their PEB is medium. Ecological learning has a vital role in shaping the EK, EA, and PEB, thus CCBS-US needs to be developed. Conclusion: The study concluded that there was a relationship between EK, EA, and PEB. The study recommends the development of CCBS-US based on the survey results.

In smart cities around the world, urban environments have become more convenient due to information and communication technology(ICT). However, extant studies reveal that the level of life satisfaction of citizens has not improved compared to that of the pre-smart city and citizens are skeptical about the role of the smart city. This is largely because local culture and needs were neglected during the planing and development of the smart city. The research was conducted on Cambodia as a pilot site and our findings indicate that middle age group's population is significantly small and the society is at risk of losing its culture. Therefore, this paper opens up various ways of embedding cultural programs using technology in order to pass down cultural heritage to young generation, provide an emotional attachment to the inhabitants and further build up a new phase of cultural legacy. This will engender cultural uniqueness to the city and intrigue tourists around the world resulting in the growth of the tourist industry. This research will contribute locally by providing a sense of community to the public and globally by suggesting applicable methodology to other cities that are under the similar context.

Hamburg's development politics like "metropolis Hamburg - a growing city" demonstrates an important economic and demographic growth during 1997 to 2008. Beyond the positive factors with the idea of creative city, only selected class of people are involved in the city's active living, the others experience only gentrification. The G$\ddot{a}$ngeviertel, where the Hamburg's working class and dockworkers had lived, will be analysed as a historical important place of the gentrification since the end of the 19'century. This paper focuses on the actual Hamburg's movement of the initiatives "Komm in die G$\ddot{a}$nge" and " Right to the City", which took over the last 12 buildings of the G$\ddot{a}$ngeviertel. The G$\ddot{a}$ngeviertel Project, with the slogan "the city is neither a business nor a brand, but a community" could be an example of an alternative and sustainable solution for better living in the urban area of the Hamburg.

This study conducted an analysis of the current use of and satisfaction with 40 village-unit core facilities that were created through a village-building project in Busan targeting users and non-users of the facilities. The study then examined ideas to promote the availability of the facilities. The results showed that for the users, they had been using the facilities for gathering and information-sharing, and the facilities were improving the interactions among the locals. In terms of non-users, the study confirmed that any relevant fields should develop diverse programs, start promotions in various ways and establish networks among neighbors to increase the non-users' use of the facilities In addition, the study found that the village-unit core facilities are working to encourage interactions among residents and that the locals' voluntary participation in operation of the facilities are needed. The study also suggested that networks across the local communities and diverse programs should be formed and developed.
