Urban parks are important spaces of ecological and socio-cultural value to citizens who lead busy lives in increasingly complex and densely populated megalopolises. However, creating and maintaining city parks takes the will of the authorities to put it into practice and provide the attendant financial resources. That explains why we are focused on the budget aspects for the Seoul Metropolitan City in relation to creating park spaces. Our findings were as follows: 1) The overall city budget has steadily increased, but the budget allocated to Green Seoul Bureau and new park development has decreased since 2011. 2) As for elected officials, the budget grew during the time of the first, third, and fourth mayors as the creation of parks was considered to be a major priority, but after the sixth popularly elected mayor, the budget was sharply cut. 3) About 10% of the budget was allocated to the parks managed by the self-governing districts, compared to the ones under the direct management of the city. Furthermore, the analysis of the average annual budget for each park and how long (in terms of year) the budget for each park is invested showed that it was classified into three different types of category. Local governments adhere to the principle that their budget must be compiled and expended for a single year, which makes it hard to establish and push ahead with a long-term plan. However, as parks and green areas should not be approached from a short-term perspective for performance but from a long-term perspective, securing the consistent amount of budget is essential. This study has significance in that it attempted to analyze the budget issues related to parks, which has not been studied in depth so far, but the subject in this paper was limited to the budget for Green Seoul Bureau. Therefore, further research is needed because the parks managed by the self-governing districts were not considered.

The Fuzzy-analytic hierarchy process (AHP) was adopted as the methodology for this study because it allows for the use qualitative judgments by experts. Based on results of the analysis of the success factors for frozen storage/cold storage warehouses, the facility factor was identified as the most important to consider. This factor had a weight of 0.307, followed by systems and operations, accessibility, and standardization/automation with weights of 0.263, 0.255, and 0.175, respectively. The conclusions and implications of the study are as follows. First, the efficiency of constant temperature and humidity systems and the heat insulation property of buildings need to be enhanced. Second, the efficiency of the operations should be enhanced through the standardization of equipment rather than by standardizing product loading. Finally, since logistics and transportation costs are higher for frozen storage/cold storage warehouses than for general distribution, accessibility needs to be considered as the first priority.

Korea established an inventory of 1,916 sites of inland wetlands during a nationwide investigation from 2000 to 2010. If inland wetlands is included in or near various protected areas designated by the government, it can be selected as a wetland to be managed with priority. This study evaluated the aspect of management of inland wetlands by analyzing the correlation between locations of national protected areas and inland wetlands. As a result, it was shown that a considerable percentage of current inland wetland was located in areas that were designated and managed as protected areas by the government, as they had a high value of natural environment protection (527 sites, 31.61 %). When the range was widened to a radius of 1 km for protected areas, 959 sites were included and 57.53 % of sites were located in or nearby the protected areas. Among them, 46.79 % of sites were distributed up to or within a 1 km radius of waterside areas and rivers; it accounted for 81.33 % of wetlands located in protected areas. Therefore, it was found that locations of current inland wetlands were mostly in contact with rivers. The results of overlay analysis were classified into high, medium and low; the correlation of location with inland wetlands was analyzed through the analysis of separation distance of various protected areas. The number of wetlands located in areas of a 'high' value of protection was 998 (59.87 %); 289 sites (17.34 %) were distributed in areas of a 'low' value of protection. This implies that these wetlands are located in artificial areas and are more exposed to environmental pressures. Thus, these wetlands could be determined as inland wetlands, which we considered for the establishment of measures to prevent damage.

The purpose of this study is to survey evaluation of the nurse on the current Performance Appraisal System. the need for future performance of the nurse and the opinions about the job rotation, and suggest the direction of improvement by obtaining basic data to improve personnel management of the nurse in a hosipial, the subject of the investigation. The study was conducted self-reporting questionniare survey of 330 nurses working at C hospital located in Chonbuk Province and the data was collected from May 4. 1999 through May 14. The research used measuring instrument developed by researcher for evalution about the present performance appraisal. the need for the future performanc appraisal system and the opinion of job rotaion. The analysis of the collected data was computerized using SPSS/PC+ program, calculated frequency, percentage, the mean and standard deviation and used Pearson, s Correlation Coefficients, t-test, chi- square test. Major findings are as follows. 1) As for the purpose of the current performanc appraisal, the appraiser recognized it as a security of promotion standard, while the employee saw it as a means for control as guidance and supervison of work. 2) With regard to use the result of the present performance appraisal, appraiser picked ambiguous appraisal standard, employees recognized unilateral evaluation of superior eliminated the participation of them as the highest priority. 3) In relation to the current criteria for promotion of the nurse, both appraisers and employees placed more weight on the length of clinical than performance appraisal score. 4) There is much possibility of the appraiser making an error to evaluate considering the length of performance appraisal. 5) Both appraisers and employees indicated that prospective result of performance appraisal should be used for the ability development & motivation of the individual. 6) Concerning employee's participation for performance appraisal both sides wanted by far more participation. 7) Regarding the most ideal appraisal method, both parties favored most the way added up the evaluation of the head nurse and peer review and followed by the manner the revaluation of the head nurse by considering self-evaluation. 8) As to the individual interview after the appraisal, more than 60% of appraisers responded it's not necessary, while above 88.5% of employees answered it is essential so that it is showed significantly difference between the appraisers and the employees. 9) As far as open of the evaluation result is concerned. 75% of the appraiser were against it but 80% of the employee were for it so that it showed significantly between them. The most principal reason that the employee want is that it motivates the individual's ability development and the fairness of the appraisal increases. 10) Whether the periodical rotation is necessary or not, 80% of appraisers and employees answered it's necessary, however, over 70% of them did not want the rotation. 11) Work-group Cohesiveness level within the nursing unit was attentive different from desire of the rotation, that is, the work group cohesiveness level of nurses wanting rotation was significantly lower than that of the group not desiring it.

The objective of this research is to assess the level of urban park service provision in comparison to demand population size by region (e.g., dong) in Busan metropolitan areas. To this end, a park service provision assessment index is utilized. The index is built upon the difference between planned and actual levels of park service provision. For each region, planned level is obtained by multiplying the per capita service amount by the number of residents in that region. Actual level is estimated based on Huff model, where distance between parks and residential locations are explicitly accounted for in model building. Empirical analysis was carried out for Busan Metropolitan Area. The result shows that Gumsung-dong, Chunga-dong and Dongdaesin3-dong are well supplied with park service, while Hadan1-dong, Goejung2-dong and Joorae3-dong are under-provided when per capita service provision amount and the extent of service area are set to $6m^2$ and 1km, respectively. It is argued that those regions that suffer from under-provision need to be highlighted such that a priority is given to those areas for establishing new urban parks when renewing urban management plan.

In case of excavation of the tunnel under weak ground conditions, such as fault zone, leg pile reinforcement with the purpose of suppressing tunnel crown settlement and side wall displacement is commonly applied. There are convergence, crown settlement, leg settlement, and the axial force of leg as a main factor for confirming the safety of support considering the installation angle and length of leg pile reinforcement according to the increase in rate of change of tunnel cross-section. In particular, the influence of right corner settlement, among variables for safety confirmation during excavation, has been analyzed as the dominant factor in the most important priority management showing larger displacement tendency than the increase in rate of the cross-section. And, it was analyzed that the occurrence tendency of axial force on leg pile reinforcement showed the influence of behavior according to the friction support concept mechanism of the pile reinforcement rather than the increase in rate of tunnel cross-section, as it showed a small increase compared to the increase rate of the tunnel cross-section which did not show a great correlation from the viewpoint of the change of the axial force by the length of each leg pile reinforcement with regards to the change in rate of increase in tunnel cross-section. If a certain length of the leg pile reinforcement is selected based on the above grounds, even if the cross-section of the tunnel in poor ground condition is somewhat larger, it has been proved to be a more reasonable method considering the workability and economical efficiency by not extending the length of the leg pile reinforcement by force.

Selecting an appropriate formwork to fit the construction of a high-rise building is an important factor that can influence the success or failure of a construction. Currently, however, the reality is that in domestic high-rise building construction, the selection of an appropriate formwork with consideration of the characteristics of the formwork has not been done in a reasonable manner. To select formwork in a systematic and reasonable fashion, comprehensive consideration is required that must not only include the aspect of construction costs, but also air, quality, safety, and environmental issues. Therefore, this study aims to rationalize the selection process of formwork by applying the scientific method of Analytic Hierarchy Process (AHP) to the selection process of formwork, in terms of construction costs, quality and safety. To do this, the researcher investigated the current status of formwork being used in high-rise residential building construction. Then, based on the results of this investigation, the researcher selected an alternative for the formwork, and taking construction experts as the subjects of this study, conducted a survey on the applicability of the formwork as well as the priority of management thereof when selecting formwork. It is judged that the results of this research will contribute a more scientific and reasonable decision-making process than the existing non-scientific method in selecting formwork for high-rise residential building construction.

Hotspots are top sites in terms of species diversity as the most threatened and most diverse sites which have been used to select priority areas for reserves. The purpose of this paper is to identify biodiversity hotspots through analyzing nationwide spatial patterns of species richness and rarity of Korean mammals. Four endangered mammals and eleven common mammals were selected as target species. Environmental variables as model input data were consisted of topography, distance, and vegetation structure etc. and Maxent was used to develop species distribution models for target species. Species richness and rarity were used as index of biodiversity. The results of this study were as follows. Firstly, hotspots of species richness for endangered mammals were in high elevation and steep mountain areas. However, species richness for whole mammals were high in low elevation of mountains. Secondly, distribution pattern of species rarity for endangered mammals were similar as richness. However, hotspots of species rarity for whole mammals were a little different from species richness. Species rarity was high in both low and high elevation of mountain areas. This study will provide the useful information for a biodiversity assessment, a habitat conservation, a national ecological network plan, and the management of protected areas.

Introduction: To analyze the impact of marketing losses on efficiency in transacting banana in Kurnool district of SRZ in Andhra Pradesh and to assess the opinions of the farmers on the constraints in transacting banana. Research back ground, Materials and Methods: The study relies exclusively on primary information obtained from the banana farmers of Kurnool District. Purposive sampling procedure was followed for the selection of the study area. Top two mandals in the district and top two villages in each mandal are selected in accordance with the area under cultivation of banana. Probability proportion to size was followed regarding the selection of sample farmers and accordingly 60 marginal, 37 small and 23 other farmers were selected and thereby, the total sample size was 120. Result and Discussion: Three marketing channels were identified in the marketing of banana in Kurnool district viz., Producer ${\rightarrow}$ Local-exporter ${\rightarrow}$ Wholesaler ${\rightarrow}$ Retailer ${\rightarrow}$ Consumer (Channel-I), Producer ${\rightarrow}$ Wholesaler ${\rightarrow}$ Cart-vendor ${\rightarrow}$ Consumer (Channel-II) and Producer ${\rightarrow}$ Juice-holder ${\rightarrow}$ Consumer (Channel-III). With the inclusion of marketing losses in the price spread analysis of banana in all the three channels, the marketing costs of all the intermediaries were increased and thereby, the farmer's share in consumer's rupee and Net Marketing Margins of the agencies are on the decline. So, without inclusion of marketing losses, the farmer's share in consumer's rupee and Net Marketing Margins of all the agencies are overvalued. The higher the marketing losses, the more is the negative impact on farmer's net selling price, net marketing margins of the intermediaries and marketing efficiency. The sample farmers are facing major problems in marketing of banana like frequent price fluctuations, unorganized marketing and lack of transportation facilities on priority basis. Suggestions: It is suggested to educate the farmers regarding the optimum maturity index for harvest, use of mechanical harvesters, proper placement of fruits during storage and ripening, better packaging and cushioning technologies to absorb shocks during transportation, strengthening of storage facilities and transport facilities, encourage co-operative marketing etc., to promote marketing efficiency of banana in the study area.

It should be accurate dose calculation to increase the efficiency of radiation therapy, and it is priority to figure out the beam characteristics for this purpose. The target and primary collimator in head components of the linear accelerator have the greatest influence on determining the beam characteristics which is caused by backscatter and it is the factor to consider the shielding structures and equipment management. In this study, we made modeling of the linear accelerator through the Geant4 Monte Carlo simulation and investigated backscatter according to the change of the size and shape in head components. For the scattered electrons, it showed the greatest number of distributions inside of the inner radius at primary collimator. But, for the scattered photons which have the high energy, it was mostly located outside of the inner radius at primary collimator. Scattered positrons showed a small occurrence in about 0.03%. According to the change of the inner radius at primary collimator, it was great changes in the inside of inner radius for all three scattered particles. According to the change of the outer radius at primary collimator, it was shown some considerable effects from more than 60 mm outer radius. It was no significant effect according to the change of target thickness. In this study, we found that backscatter should be considered, and figured out that geometric size and shape of the peripheral components are the factors that influences the backscatter effect.
