본 연구는 자율주행 자동차를 이용하고자하는 의도에 영향을 미치는 요인을 실증적으로 분석하기 위해 이루어졌다. 실증 분석을 위한 연구모형은 가치기반수용모델(VAM)을 기반으로 자율주행 자동차의 특성을 반영하여 도출하였다. VAM의 기본 변수인 유용성, 즐거움, 기술성, 인지된 비용에 자율주행 자동차의 특성인 편리성, 안전성, 보안성, 사회적 영향을 추가하였다. 이렇게 도출된 모형을 바탕으로 실증 분석을 위해 설문조사를 실시하였으며 유효한 216부를 분석의 대상으로 삼았다. 실증분석은 AMOS24를 활용한 구조방정식으로 하였다. 실증 분석 결과는 다음과 같다. 유용성, 즐거움, 편리성, 안전성, 보안성은 인지된 가치에 유의한 영향을 미쳤다. 기술성과 인지된 비용은 인지된 가치에 대한 영향 관계가 부(-)로 나타났다. 한편, 보안성과 사회적 영향은 인지된 가치에 유의한 영향을 미치지 못한 것으로 나타났다. 인지된 가치는 사용의도에 미치는 영향에 있어서 유의한 영향을 주는 것으로 나타났다. 유의한 영향을 미친 변수들의 영향력은 안전성, 편리성, 인지된 비용, 즐거움, 유용성, 기술성 순이었다. 한편, 인지된 가치의 매개효과를 분석한 결과 인지된 가치는 유용성, 즐거움, 편리성, 안전성, 기술성, 인지된 비용과 사용의도 사이 매개의 역할을 하는 것이 검증됐다. 반면 보안성 및 사회적 영향과 사용의도 간에는 유의한 매개효과가 검정되지 않았다. 이러한 연구 결과를 바탕으로 본 연구가 가지는 학술적, 실무적 시사점을 제시하고자 한다.

The multifamily housing has various advantages in construction cost, land-use intensity. KRIHS(1997) recommended the proper scale of th multifamily housing as 800 households in constructability, 1,000 households in facility compactability, 500 households in social aspect. At the early planning stage of project, the size of the multiftmily housing has, until now, been maximizingly considered under the regulation on which has been emphasized at the building volume ratio, land area, etc., except for the expenditure during the maintenance stage. This paper aimed at providing the proper size of multifamily housing in aspect of area and household number with maintenance cost at the early stage of project. For these, it took 곧 average cost function which is made from the 3-rd quardratic form and analyzes the unit increasing rate of the average cost. It surveyed in nationwide focused on the central heating system using diesel and kerosene. The number of samples is 88 and items of management cost is 11. The results are as follows ; first, 3rd-order quadratic function is proper at explaining the cost variation, considering the multicollinearity and statistics. Second, the proper size of multifamily housing is recommended with 83,000 $m^2$ on management area, 820 or over the 2,630 household number in aspect of total management cost.

The aim is to get comprehensive view point for the price of apartment. Apartment construction cost is the sun of land cost and building cost. Land price reflects the value of location where building stands. When the gap between price and affordability is narrow enough, effective demand promote apartment construction. The today's trends of rising price, which began in apartment housing, spreads to real estates market and finally overall consumer price. Problem is that price is decided only by supplier's interest. Equilibrium-pricing is common process in housing market. However it is important to review hedonic price and the factor of housing services and focused on the affordability of demanders. AHP analysis was used to study real needs and preference of demanders and dealt with 200 interviewees with brief checklists. We found that social factor is more important than building cost or site development. Especially location of apartment is most important to affect environment quality and accessibility to facilities.

Organization wishes to develop newer and more complex system according as social structure is more complex and a technology develops more. Therefore, field of system engineering in development of new system is realized by all-important essential boundary. However cost of SE have considered restrictively being not about SE cost having applied SE. About this problem, this study provides COSYSMO as model for SE cost estimation, as the application example, estimate SE cost for smart UAV system applying COSYSMO in PRICE Trueplanner.

The purpose of this study was to investigate the differences of child care and it's costs between the full time housewives and employed wives' families with preschool children. the results of this study were as follows ; 1) The child care was performed primarily by herselves in the case of full time housewives' families, whereas the child care of employed wife families was done by babysitter or nursing facilities. 2) Most of unemployed wives' families undertook the burden of time cost, whereas the families of employed wives had to pay heavy expenses of money cost f9or the child care arrangements 3) In the estimation of money cost for the child care arrangements income had the highest effect. In contrast with this, in the case of time cost, occupational status of housewives had the highest effect. It was suggested for enhancing the sense of well - being of housewife it is necessary to perceive the value of household production and the social support for child care arrangements in all families, whether unemployed or employed.

This paper aims to estimate the social discount rate (SDR) rather than dig into its theoretical foundation. As SDRs can be derived by investigating both the rate of return on investment and the social time preference rate, we estimate the marginal productivity of both private and public capital and the time preference rate based on the Euler equation. In order to provide a single representative SDR, the weighted averages of the marginal productivity and time preference rate, whose weights are determined by the flow of funds data reflecting the social demand of funds, are presented. Based on the empirical results, we argue that the marginal productivity of private capital stands in the middle of the 3% range while that of public capital varies from 4.5% to 8.6%, with the time preference rate showing a decreasing trend from 3.2% in the early 2000s to 1.2% by around 2030. The single representative SDR or the weighted SDR is estimated to be approximately 3.0~4.5% and expected to continue its downward trend for the foreseeable future.

In this study, we developed a method to quantify urban social costs using mobile sensing data, providing a novel approach to urban planning. By collecting and analyzing extensive mobile data over time, we transformed travel patterns into measurable social costs. Our findings highlight the effectiveness of big data in urban planning, revealing key correlations between transportation modes and their associated social costs. This research not only advances the use of mobile data in urban planning but also suggests new directions for future studies to enhance data collection and analysis methods.

본 연구는 사회적 기업을 추진하고 있는 기관들의 욕구를 파악해 올바른 사회적 기업 지원정책을 마련하기 위한 기초자료를 제공하는데 있다. 분석결과, 극복되어야 할 내부 장애요인으로는 운영자금 및 투자자금의 부족이 지적되었고, 사회적 기업 전환 전에 선행되어야 할 조건으로는 재정지원이었다. 사회적 기업으로의 전환과정에는 기업설립 및 운영에 필요한 운전자금 확보가 필요한 것으로 나타났고, 정부와 지방자치단체가 가장 시급히 해야 할 지원은 인건비 지원, 우선 구매 및 우선위탁 의무화였다. 향후 정부와 지방자치단체를 중심으로 사회적 기업의 운영에 필요한 설비와 인력을 갖출 수 있도록 초기자금을 지원하고, 사회적 기업의 상품과 서비스 판로개척을 지원해야한다.

We report for the first time the life history of a 'social' spider, Philoponella prominens, living in a temperate region. Philoponella prominens hibernated as immatures or subadults for 7-8 months in 1995 and 1996 from September-October to April-May in central Korea. When they emerged from their winter hibernation, a majority began their lives as commensals in the webs of other species. As the mating season approached, however, commensal spiders switched to become colonial or solitary. The mating season began in early June and lasted until early August. Newly-hatched spiderlings began to appear in the field in late June. They formed a colony by building their webs connected to the mother's by using pan of the mother's web as supporting substrates. As the season progressed, however, some of the colonial spiderlings became commensal or solitary individuals. Our field observations suggest that Philoponella prominens form colonies or commensal associations to reduce the web-building cost.
