This study was conducted to survey and diagnose operation status of the agricultural machinery rental service, analyse and compare operational efficiency among 82 city and county ATDEC (agricultural technology development and extension center) using the DEA (Data Envelopment Analysis) method, and recommend future direction, for improvement of the business. Input variables were invested budget and labor, and output variable was rental return. Percentages of return to investment on the rental service were calculated as 68.3% and 63.9% when analyzed with CCR (Charnes, Cooper and Rhodes) and BCC (Banker, Charnes and Cooper) models, respectively, indicating inefficiency of the service operation. Increase of rental charge would increase efficiency by 63.9~68.3% depending on models, and decrease of financial and labor investment would improve the efficiency by about 11.3%. Technical efficiency would be more important than scale efficiency, therefore adjustment of over-invested budget and labor needed to be made together with increase of rental charge to improve the operation. Among the ATDECs providing the rental service, 6 (7.3%), 43 (52.4%), and 33 (40.2%) were in state of CRS (constant return to scale), IRS (increasing return to scale), and DRS (decreasing return to scale), respectively. These indicated public aspects of the rental system, over-investment, lack of output component for input component, meaning that scale income would be increased by qualitative expand of rental charge. Efficiency analysis of the rental system by region showed that efficient ATDECs to be benchmarked by others were in the order of DMU-70, DMU-54, DMU-29, DMU-5, DMU-22, DMU-2, and DMU-61. More comprehensive and extensive survey and analyses would be necessary in the future.

2001년 이후 주택가격의 상승에 따라 저소득층의 주거비 부담이 가중되고 있다. 이러한 문제를 해결하기 위해서 정부에서는 국민임대주택의 지속적인 공급과 더불어 민간주도의 공공임대주택의 확대공급을 적극 장려하고 있다. 주거비 보조제도는 선진복지국가에서 저소득층 세입자의 주거문제해결을 원조하는 방법의 하나로서 임대료 통제 및 공공임대주택의 공급과 더불어 3대 정책수단으로 인식되고 있다. 국내에서도 국민기초생활보장법에 임대료와 수선비 지원이 가능한 주거급여가 제한적으로 포함되어 있으나, 공공임대주택사업의 경우 아직 뚜렷하게 제시된 수익률에 관한 명확한 기준이나 체계가 없어 본격적인 제도발전을 위한 연구가 필요한 단계이다. 따라서 본 연구에서는 공공임대주택사업의 적정 수익률의 산정과 더불어 저소득층의 주거 비 지불능력을 고려한 주거비 보조금액의 기준 제시를 목적으로 한다.

상용의 소프트웨어를 사용하기 위해서 대부분의 소프트웨어 사용자는 그 소프트웨어를 구입하여야한다. 하지만 해당 소프트웨어에 대한 사용 시간이 길지 않은 경우, 그 소프트웨어 비용은 과다한 지출로 인식된다. 소프트웨어 임대 서비스는 이러한 경우 효과적인 대안일 수 있다. 소프트웨어 임대를 지원하기 위해서는 요금 부과 기법이 필요하다. 두 종류의 요금 부과 기법이 생각될 수 있다. 하나는 특정 기간 소프트웨어 사용에 대하여 일정한 요금을 부과하는 것이며 다른 하나는 실제 사용한 시간에 따라 요금을 부과하는 것이다. 이 논문에서는 소프트웨어의 실제 사용 시간에 따라 요금을 부과하는 기법을 제안한다 소프트웨어의 실제 사용 시간에 따라 요금을 부과하기 위하여 사용 시간을 정화하게 측정할 수 있는 기법을 고안하였다.

Status survey on short-term agricultural machinery rental business was conducted to provide basic data for effective and sustainable implementation of the rental system. Selected survey samples were 34 rental management institutions such as city and county level government offices and agricultural technology development centers, and Primary Agricultural Cooperatives. Survey was conducted through mailing of questionnaire papers and direct interviews with the officers in charge of the agricultural machinery short-term rental management. Number of agricultural machinery retained by the 34 management institutions for the machinery rental business was 3,699, and numbers of the machinery were 1630 for upland crops, 929 for rice, 542 for orchard farming, 274 for animal husbandry, and 324 for common use. Regarding size of warehouse for rental agricultural machinery, 50% of the institutes were less than 660 $m^2$, 26.5% were greater than 993 $m^2$, and 23.5% were between 663 and 990 $m^2$. Institutes maintaining machinery washing facilities were only 10 (29%) among the 34 rental management institutions. Agricultural machinery rental business was advertised to farmers by 91% of the institutes, and the methods were leaflet (35.2%), village broadcasting (26.5%), call-up education (23.6%), and TV and radio (14.7%). Major contents of the advertisement were rental procedure (52.9%), rental machinery (26.5%), and rental cost (20.6%).

The aim of this study is to provide primary data to propel business intended for the entire nation through the analytic assessment of the propulsion process of the newly attempted 'Dagagu' Housing Purchase and Public Rental Program (DPPRP) for the cities low income bracket. The study method was to conduct analysis of data, interview survey, onsite tenant interviews and examination of the locale in order to analyze the execution of the program and experiences of the administrator in charge of executing the model program. In the case of the enforcement of the 'Dagagu' Housing Purchase and Public Rental Program(DPPRP), combined teams of the specialty fields of purchase, rental, and management are needed; operation propulsion system of the purchase process of the housing, rental process for selecting the tenant, and the entire process of management afterwards needs to be maintained; and a collaboration system with related organizations need to be constructed.

Short-term agricultural machinery rental system has been operated by agricultural extension organization of local government (agricultural technology center) and sponsored by Ministry of Agriculture, Food, and Rural Affairs, to improve utilization efficiency and save agricultural production cost through joint utilization of agricultural machinery. This study was conducted to analyze current status of the rental system operation and provide recommendations for future direction. Question survey was conducted for officers in charge of the rental system in the technology center, and strategic improvement was suggested through importance performance analysis (IPA). Survey results showed that 11 issues should be reformed or improved by 2015, which is not practically feasible. IPA analysis resulted that administration and manpower support, cooperation between federal and local organizations, and cooperation with other organizations should be focused for successful operation of the rental system. Issues that seem to happen after 2015 need to be handled as future research.

The main objectives of this study were to determine the differences in the personal. physical. socio-psychological characteristics of the elderly and the housing features according to housing types. This study classifed housing types into 4 types purchased apartment, public rental apartment charge-free institutional housing for the elderly and private housing facility for the elderly. On the basis of the findings. these al·e the following conclusions: Generally, the morale of residents in elderly facilities was higher than that of the apartment residents’. This result could support the development of senior housing in Korea Residents of rental apartment were younger and their functional health and level of independence were higher than that of others. Therefore rental housing would be an alternative housing for the independent low-income elderly. However the morale of rental housing residents was lower than that of ethers. The elderly housing facility residents’ recongnition of the housing managers’ leadership style was higher than that of the apartment residents’. This result ensures the importance of housing manager’s role in managing senior housing.

In popular tourist destinations such as Jeju and Gangwon, electric rental cars are increasingly adopted. However, sudden battery drain due to weather conditions can pose safety issues. To address this, we developed a battery consumption analysis model that considers resistive energy factors such as acceleration, rolling resistance, and aerodynamic drag. Focusing on the effects of ambient temperature and wind speed, the model's performance was evaluated during an empirical validation period from November to December 2023. Comparing predicted and actual state of charge (SoC) across different routes identified ambient temperature, wind speed, and driving time as major sources of error. The mean absolute error (MAE) increased with lower temperatures due to reduced battery efficiency. Higher wind speeds on routes 1 and 6 resulted in larger errors, indicating the model's limitation in considering only tailwinds for aerodynamic drag calculations. Additionally, longer driving times led to higher actual SoC than predicted, suggesting the need to account for varying driver habits influenced by road conditions. Our model, providing more accurate SoC predictions to prevent battery depletion incidents, shows high potential for application in navigation apps for electric vehicle users in tourist areas. Future research should endeavor to the model by including wind direction, HVAC system usage, and braking frequency to improve prediction accuracy further.
