  • The purpose of this thesis was to improve the plans and methods of teaching and learning activities and contribute to developing teachers` quality and reeducating them by investigating teachers' attitudes toward teaching and learning have a significant effect on the students' attitudes toward mathematics and the students' ability development at mathematics. The inventory was composed of 56 items : three main areas and eight sub-areas. Added seven background factors were sex, by whom was established (is it a public or nongovernmental \ulcorner), teaching career, age, what kind of school (is it general or vacational high school or middle school\ulcorner), region, college. For this analysis of materials used SAS program. And analysis of variance was applied on the seven background factors. All subjects in this study were 341 secondary school mathematics teachers in pusan city and Kyungsangnam-do were surveyed by the questionnaire of Likert type to which the respondents' seven background elements were added. Main results this study were as follows : 1. The overall attitude of the measured secondary school mathematics teachers tends to be positive but a little indifferent. Also attitude toward the students was a little more positive than the other attitudes. 2. There were significant differences (1%) among the sub-level areas except three of them. (r = 0.17~0.60) 3. There were significant differences (5%) by the result of Multiple comparison test among the schools in learning and teaching. So the teachers working at middle schools and general high schools were more positive than those working at vocational high schools. 4. The result of comparison among region was that teachers working in towns and cities were more positive than those working in the country. But there was no significant difference between the teachers working in large cities and those working in other region. 5. There was no significant difference in the overall attitudes toward teaching and learnig among the sex, by whom was established(is it public or nongovernmental\ulcorner), teaching career, age, college. The study left much deficiency to be desired and has to be followed by a continuing study to make it better. For the following study, it is necessary to examine the validity and reliability of the measuring tools more thoroughly and investigate the attitudes with sufficient samples all over the country.

  • Objectives: The changes in atmospheric $PM_{2.5}$ concentrations were extensively studied in one metropolitan city (Incheon), two small and medium sized cities (Gunsan, Cheonan), and a rural area (Gosan in Jeju). The concentrations of heavy metals (Cr, Mn, Fe, Ni, Cu, Zn, Al, Pb) and the component features of $PM_{2.5}$ were determined for these areas. Methods: This study sampled $PM_{2.5}$ at the designated locations in the metropolitan (Incheon), small and medium sized cities (Gunsan in Jeonbuk and Cheonan in Chungnam), and rural area (Gosan in Jeju) to investigate concentrations with a sampling device (Sequential sampler, APM Eng., Korea). Sampling was undertaken over months, from June 26 to November 26, 2009. Sampling was conducted a total of 44 times, with routine sampling at intervals of six days (24 total times) and intensive sampling (20 total times) during the summer and fall. Mass concentration of $PM_{2.5}$ was evaluated and the concentrations of heavy metals (Cr, Mn, Fe, Ni, Cu, Zn, Al, Pb) were analyzed. Results: The geometric average of concentrations of $PM_{2.5}$ per district was $35.289{\mu}g/m^3$ for Cheonan, $29.955{\mu}g/m^3$ for Incheon, $24.119{\mu}g/m^3$ for Gunsan, and $18.773{\mu}g/m^3$ for Jeju, respectively. The average concentration of $PM_{2.5}$ in Cheonan was the highest. The seasonal concentration distributions per district showed Cheonan $33.387{\mu}g/m^3$, Incheon at $31.550{\mu}g/m^3$, Gunsan $22.900{\mu}g/m^3$, and Jeju $18.900{\mu}g/m^3$ in the summer. For the autumn, the concentrations were $36.873{\mu}g/m^3$ in Cheonan, $28.625{\mu}g/m^3$ in Incheon, $25.227{\mu}g/m^3$ in Gunsan, and $18.667{\mu}g/m^3$ in Jeju. According to the collected data, the concentration showed a tendency to rise during the autumn in all of these regions with the exception of Incheon. For heavy metal distribution per district, Fe showed an elevated concentration during the summer while high concentrations of Pb and Zn occurred during the autumn. Conclusion: These results demonstrated that atmospheric factors affected the concentrations of heavy metals. The results of this study could be used as foundational data for setting environmental air standards focusing on a $PM_{2.5}$ receptor.

  • Because local cities are different from large cities, they need to reflect their own characteristics of housing market. Thus in order to obtain useful implications for the establishing sound housing market in Jinju City, this paper investigated the characteristics of spatial distribution and determinant factors that affect apartment price in Jinju City. GIS representation of the apartments showed that most of old and small apartments were built in 'land readjustment project' areas executed in 1970s. On the contrary, new and large scale apartment complexes were built quite recently and distributed in the western and southern parts of the city. Next, in order to examine the factors which affect apartment price, this paper subtracted firstly several variables from the related studies. However in order to avoid multi-colinearity, variables were summarized by means of factor analysis. Then, setting apartment price as a dependant variable, 12 hedonic price models were established with 33 independent variables. As results, building age, floor area, accessibility to university and hospital, accessibility to arterial road, and stair-type building were turned out to be significant. These results will be used in making the supply and allocation plan of urban facilities and housing. Finally as conclusions this paper emphasized the need of periodic analysis of local housing market and establishing detailed housing information systems.

  • Recently, Low Impact Development (LID) has been emphasized as a critical strategy for improving urban water cycle and adapting to climate change. LID is needed to be incorporated in urban planning and development process for effective implementation in the real world. However, little research has examined the relationship between urban planning and LID in Korea. This study addresses this critical gap by 1) examining whether current urban planning institutional system considers LID or not and 2) assessing the extent to which local comprehensive plans integrate LID in seven large cities. Study results show that a few planning guidelines declaratively mention the need of LID but they don't include specific LID strategies. In addition, we found that 7 local comprehensive plans in the sample received a mean score of 11.71, which represents 19.52% of the total possible points and there are wide variations among cities. These findings indicate that there is still considerable room for improvement of local governments on LID. We propose the revision of planning guideline by incorporating LID principles and non-structural and structural LID technologies.

  • This study estimates the WTP for the plan of solving deforestation due to limestone mining and calculates that damage cost using contingent valuation method. As the results of analysing a dichotomous choice CV data, the yearly mean WTP per household for the plan is 5,045 won(95% confidence interval : 3,729~6,360 won) in single bounded CV model and is 4,361 won(95% confidence interval : 3,710~5,012 won) in double bounded CV model. The damage cost of deforestation due to limestone mining can be estimated as 55.3% of WTP for the plan which is assigned to restoring the deforestation area to the original or similar alternative state. The average yearly deforestation cost of 1 ha due to limestone mining is reached 20.90 million won(95% confidence interval : 16.53~25.27 million won). And the asset value of that 1 ha damage is 160.02 million won(95% confidence interval : 126.56~193.49 million won). The fact is found that the damage cost of deforestation using replacement cost method is likely to be underestimated. The total damage cost of deforestation because of limestone mining in 3 cities (Donghae, Samcheok, Yeongwol) is 204.0 billion won(95% confidence interval : 161.4~246.7 billion won) which is composed of 26.5% for Donghae, 28.9% for Samcheok, and 44.6% for Yeongwol according to the damage size of deforestation due to limestone mining in 3 cities.

  • A number of cities have been constantly decreasing their residents by the low quality of life and environment. A creative industry is being noticed for not only securing the competitiveness of the city but also increasing the number of population. Thus, the urban structure for inducing creative industry population becomes to major issue to the most of local governments. This study aims to suggest the relationships between urban structure and creative industry population based on different urban sizes. To measure the population of creative industry, this study used the 'National Business Survey' by the National Statistical Office, which classified the statistical data of industrial places on a basis of city, district, and borough. Based on the results of expert questionnaire surveys, it conducted an analysis on the importance of urban structure and drew some critical factors that have an important effect on attracting the population of creative industry. The relationships between creative industry population and urban structure evaluated by multiple regression analysis. This study found out that the cultural factors like cultural space or culture events were drawn as very significant factors that have a positive effect on the population of creative industry population. It is judged that the creation of culture environment, which can enrich the creative industry, is needed to strengthen the competitiveness of the cities.

  • With the recent increase in the demand for corporate trust based on transparency in accounting, such as management disclosures and autonomous management disclosures for Social Innovative Enterprises, the duties of Social Innovative Enterprises on accounting and tax affairs have become important. This study looked at the effects of NCS accounting, audit and tax functions on the sustainability of Social Innovative Enterprises, which have not been studied. In particular, issues such as management disclosures and adequacy of financial statements depend on how ethically the accounting officer performs the work. Accordingly, we looked at the intermediation of accounting ethics held by the person in charge of accounting in relation to the sustainability of the NCS accounting, audit and taxation functions. The research subjects surveyed 500 people in charge of accounting at 50 social innovation companies, including social enterprises established in special cities and metropolitan cities such as Seoul and Busan, as well as social cooperatives. A path analysis was conducted with 372 valid questionnaires. As a result of the analysis, NCS accounting, audit and tax functions have a significant impact on both economic value and social value and environmental value, which are the sustainability elements of Social Innovative Enterprises. It was also found that NCS accounting, audit and tax affairs had a significant impact on accounting ethics, and accounting ethics had a significant impact on social and environmental values, excluding economic values. In addition, accounting ethics were found to have a mediated effect between NCS accounting, audit and taxation functions and the sustainability elements of Social Innovative Enterprises. In particular, the relationship between NCS accounting, audit and tax affairs and social value was found to be completely mediated.

  • This survey was done to construct a nursing theory according to Korean culture and to identify the Korean traditional view. From ancient time until now, shamanism has played an important role as determinant of Korean culture and of the personality formation of Korean people. The subjects are 321 patients and member of their families who were over 18 years old, and who are living in five large cities and two rural communities in Korea. Data collection was done from March, 8th to April, 29th in 1999. SPSS The tool developed by the investigator through literature review was used to measure the perception and the attitude of patients and their families to Korean shamanism. Collected data were analyzed by frequency, percent and $x^2$ test with SPSS program. The results are summarized as follows ; 1) While 35% of respondents answed that the destiny or fate(八字) was only relied on the abilities and endeavor of individual, 65% of respondents were fatalists(運命論者) or eclectic(折衷主義者) are compromised between the fate and endeavor. 2) While half of the respondents belief in divination(占) to some degree, the rest of them reported hardly any belief in divination. 3) There were almost twice as many respondents who directly consulted fortune-tellers were as respondents who did not consult fortunetellers. 4) The reasons for consulting fortunetellers were job problems, home problems, health problems by in that order. 5) The respondents almost always interpreted the cause of physical disease and mental disease as being psycho-sociological, but 1% of them explained mental disease as a shamanistic manitestation. 6) In case of disease, the reasons for consulting a fortuneteller was a) no hope of recovery from the sickness in any other way, b) the chronic disease in that order. 7) Of the respondents, 65% answered that diseases could not be cured by a 'Gut' (the performance done by the shaman), but 27% of respondents thought that disease could be cured by a 'Gut' in the case of mental disease. 8) Sixty six percent of the respondents answered that they have experienced praying for their wishes with clean water(井華水). 9) While 54% of the respondents answered that they have seen or heard the 'Beung Gut'(the performance to pray for recovery of sickness done by the shaman), 46% responded that they have never seen or heard it. 10) To the question 'do you intend to have a 'Beung Gut', 51.7% of respondents answer 'no' strongly, but 48% of them say 'yes' or took a compromising attitude. 11) Generally the respondents differed in perception and attitude to shamanism. In short, females more than males, old aged more than younger aged, lower educated more than higher educated, believers in Buddhism more than believers in any other religion, and blue color more than white color have more positive attitudes to shamanism. Also men living in rural communities have more positive attitude to shamanism than men living in the large cities. Consequently, Shamanism can be understood as an anxiety relieving cultural system even though Shamanism itself looks like a cultural complex.

  • This study aims to identify the effects: quality of chest compressions, height and weight of pregnant women cardiac arrest while lying $30^{\circ}$ inclined to the left has on the quality of chest compressions administered by 119 EMT. For the purpose of this study, 62 members of 119 EMTs in M, N, S, Y cities and G cities of J province agreed to join in the test and the test was conducted from June 15 to 16 in 2015. Two mannequins (Resusci Anne$^{(R)}$) were used for the study and the chest compression process was recorded with the use of the Laerdal PC Skill Reporting System$^{(R)}$. As a result, it was discovered that for patients with a $30^{\circ}$ left inclination, who were below 170 cm in height and 65 kg in weight, the proper frequency and depth of compression were unsatisfactory. With this in mind, training programs and instruments that can improve the quality of chest compressions depending on a person's (patient's) height and weight should be developed.

  • This study focused on developing strategies of cyber-compact city, combining compact city with information and communications technologies(ICTs), in order to enhance sustainable transportation. The cyber-compact city development is defined as a development that is able to reduce travel by ICTs and encourage people to use transit or non-motorized vehicles such as bicycles for ICT-induced travel (especially, discretionary travel) by compact and mixed land use. It can be achieved with combining cyber and compact strategies with respect to network, node, and area. For example, ICT network may use transit network facility, a transfer station may be a hub of ICTs, and transit influenced zone may work with ICT service area. We proposed three cohesive strategies for the cyber-compact city based on literature review and case studies on cyber and compact cities. The first strategy is a cohesion between public transportation and telecommunication network by centering on the two for national and urban spatial linkage structure. That is, cities or urban centers and its peripheral areas can be connected by rail network, and extra space of railway network can be used for constructing telecommunication network infrastructure. The second strategy is a cohesion between public transportation node and telecommunication node by building up regional and urban telecommunication centers near to or at main railway stations. For this strategy, telework centers and communication service centers should be established mainly at transfer stations. The third strategy is a cohesion between public transportation impact zone and telecommunication impact zone as transit oriented development.
