This study is to survey facilities installed at urban parks and identify park facilities desired by users through a questionnaire survey of users who actually use the parks. Then, the outcome will be compared and evaluated to install urban park facilities that reflect the desires of users in the future. Findings showed that park facilities currently installed are mostly those easy to install and manage among facilities suggested in relevant laws. Regardless of park types and sizes, similar facilities were installed across parks. A questionnaire survey of users showed that they wanted facilities to rest, sports facilities, waterscape facilities and facilities to accompany families. The result also showed that they wanted green area-style parks that have a lot of trees. Therefore, going forward, facilities reflecting such desires of users should be installed at parks as much as possible. When developing a park creation plan for each city, it would be critical to survey the opinions of residents in relevant areas in advance and reflect it to the creation plan.

The need for improvement is raised due to limitations with environmental impact assessment, and the importance for data-based environmental impact assessment is increasing. In this study, data demand was derived by analyzing Agreed Terms and Conditions in the Water Environment field (Water Quality, Hydraulic & Hydrologic Conditions, and Marine Environment) of environmental impact assessment. Agreed Terms and Conditions on environmental impact assessment in the water environment field were classified and categorized by environmental impact assessment stage (addition to status survey, impact prediction and evaluation, establishment of reduction measures, post-environmental impact survey), and data demand for each type of consultation opinion was linked. As a result of the categorization of Agreed Terms and Conditions, it was classified into 18 types in the water quality, 15 types in the hydraulic & hydrologic conditions, and 17 types in the marine environment. As a result of linking data demand, the total number of data demand was 236 in the water quality, 98 in the hydraulic & hydrologic conditions, and 73 in the marine environment. The highest number of Agreed Terms and Conditions and data demands were found in the water quality for the evaluation item and establishment of reduction measures, specifically establishment of non-point source pollution reduction measures, for the stage. The numbers were judged to be linked to the relative importance of the items and the primary purpose of environmental impact assessment. The derivation of data demand through the analysis of Agreed Terms and Conditions in the environmental impact assessment can contribute to the advancement of the preparation of environmental impact assessment reports and is expected to increase data utilization by various decision-makers by establishing a systematic database.

To accurately forecast the supply and demand of harbor pilots, it is necessary to derive the determinants of demand because they are directly linked to securing the safety of ships and ports. The securing of an appropriate numbers of harbor pilots can create conflicts of interest among the pilots, the Ministry of Oceans and Fisheries, and users of pilotage services as it is also a matter directly related to harbor pilots' income. Therefore, a measure is needed to ensure a suitable number of pilots can be maintained, through which high quality pilotage services can be provided. This can be achieved by deriving reasonable determinants for estimating and forecasting demand, which satisfy all stakeholders involved in pilotage service. To reveal the challenges posed by the current determinants regarding the demand for harbor pilots used by the Central Pilotage Operation Council, and arrive at solutions, this study derived three determining factors, namely the total annual average piloting time, the average working hours of pilots, and the current number of pilots. These were used to determine the demand for harbor pilots. This study used a survey and analysis of current determining factors, a questionnaire survey administered to the interested parties, a case study of selected countries, and so on, as the research methodology.

This paper estimates the demand of newly married couples for public rental housing in Chungnam. This research attempts to overcome data limitations by linking survey data with administrative data for analysis. First, the results of a binary logit model that analyzes newly married couples' intention to move into public rental housing, based on the Chungnam Social Survey 2019, reveal that residential location, educational level, housing type, and tenure type have a statistically significant effect. By combining the estimated coefficients with another dataset, the statistics of newly married couples for administration purposes acquired from Statistics Korea, this research estimates the demand for public rental housing among the newly married couples in Chungnam. The estimation results show that the total demand for public rental housing in Chungnam is 11,424 units among 43,705 newly married couples. The total demand of 21,685 newly married couples who occupy rental housing is estimated to be 9,436 units. The policy for providing public rental housing to newly married couples in Chungnam aims to increase their fertility rates. Hence, further research should be followed up to evaluate the effect of the supply of public rental housing on fertility rates. Also, a research method should be developed to control for possible endogeneity between the demand for public rental housing and childbirths.

The purposes of this study are to investigate the determinants of household demand for credit and to test the effects of credit outstandings and credit repayments on consumption expenditures. To investigate the relationship between credit use and consumption expenditures, a theoretical consumption expenditure model including credit outstandings and credit repayments is developed. With 1991 Report of National Survey of Family Income and Expenditure, two empirical models are tested using OLS. The results show that household demand for credit is determined by household income, debt burden, household size, age and squared age of household head and ratio of home ownership. It is also found that credit outstandings affect consumption expenditures positively while credit repayments affect consumption expenditures negatively.

Personal Air Vehicle is expected to be a promising solution to relieve traffic congestion using urban airspace. The development of related technologies such as materials or batteries has been accelerated. In addition, commercial transportation services are being prepared. When fierce competition begins in the PAV market, even technologically superior products will disappear without choices by consumers. Therefore, demand factors should be reflected in PAV development to enhance competitiveness. In the paper, values were estimated for the major technological attributes of PAV. Stated preference data were collected through a survey, and the conjoint method and ordered probit model were adopted. Thereafter, it was confirmed that the value would be high in the order of dual mode, drone-type appearance, and noise reduction. Some R&D strategies were proposed based on this.

Based upon the Labor Demand Survey and the Survey on Wage Structure being conducted annually by the Ministry of Labor, we suggest a convenient statistical tool which can analyze and appraise the effect of introducing a new survey method. Since both surveys have in common very similar sampling frames and sampling schemes in structure, one can measure the variability of one survey on the basis of the other. The influence appraisal method adopted here is applied to ratio data between two independent estimates belonging to the identical category by year and has a statistical form of comparing ratio data before introducing a new survey with those after introducing a new survey.
