세대별 은퇴 후 주거입지 선호 특성에 관한 연구

This study aimed to analyze the similarities and differences in retirement location preferences among Baby Boomers, Generation X, and the Echo Generation. An empirical analysis was conducted on 211 residents of the Seoul metropolitan area for this purpose. The findings revealed that, regardless of generation, the most preferred area for retirement housing were small and medium-sized cities in Gyeonggi-do. Additionally, Baby Boomers and Generation X preferred large cities in Gyeonggi-do, whereas the Echo Generation favored Seoul. Residents of Seoul, irrespective of their generation, showed a strong preference for Seoul, followed by large cities in Gyeonggi-do for Generation X and small to medium-sized cities in Gyeonggi-do for the Echo Generation. Those living in Gyeonggi-do, regardless of their generation, also preferred smaller cities within the region, followed by the larger cities. Among individuals wishing to reside in the metropolitan area post-retirement, the eastern and southern regions of Gyeonggi were the most favored areas across all generations. Regarding the type of area they preferred to move to after retirement, Baby Boomers had a preference for purely urban areas, while Generation X showed a preference for a combination of urban and rural areas. The Echo Generation, on the other hand, exhibited similar preferences for mixed urban and rural areas and purely urban areas. On the other hand, in the case of the echo generation, preferences for mixed urban and rural areas and urban areas were similar. In terms of selecting a post-retirement residence, transportation access was the top priority for Baby Boomers and Generation X, whereas living convenience was paramount for the Echo Generation. The study concluded with academic and practical implications based on these findings.

고령자 지원주택 수요․공급 분석 및 인식조사 연구

According to a survey on the elderly, the majority of elderly people prefer to spend their golden years receiving care at their place of residence rather than entering a nursing facility. However, if their health is frail or semi-dependent and they need care but do not have family members to take care of them, there is no other option other than a nursing facility. Since the introduction of long-term care insurance for the elderly, the increase in nursing facility protection is causing negative results by lowering the quality of life of the elderly and increasing social costs. As a solution to this situation, supportive housing for the elderly rather than nursing facilities is emerging as an alternative. The purpose of this study is to identify awareness of supportive housing for the elderly and priority supply areas in order to preemptively respond to a super-aged society and provide stable community housing for the elderly, and use it as important basic data when promoting future projects. To this end, we analyzed the awareness of public and private experts on the general indicators needed when establishing the elderly supportive housing project plan. In addition, we analyzed the demand for care by identifying the elderly population who are consumers of supportive housing, and analyzed the supply of care by analyzing the status of elderly welfare facilities with similar functions to supportive housing. By analyzing the discrepancy between care demand and care supply, we analyzed priority supply areas that urgently need supportive housing for the elderly. In a reality where we are expected to enter a super-aged society and face a rapid population aging, we are identifying the discrepancy between supply and demand for elderly care in order to improve the quality of life of the elderly and reduce social costs. Efforts to preemptively respond to a super-aged society through research and analysis of priority supply areas for supportive housing for the elderly are no longer an option but a necessity.

Broiler production from the perspective of emergy analysis - environmental impact scenarios

Poultry meat consumption is a significant element in Poland's overall food consumption. Economic considerations mean that both nationally and globally, conventional intensive rearing dominates. Nevertheless, environmental and health aspects or the will to treat animals humanely make pro-environmental rearing systems increasingly common. The purpose of this article is an environmental analysis of an example farm engaged in intensive rearing of slaughtered poultry (so-called baseline production). For the analysed production, the following scenarios of changes were proposed: (a) conventional rearing based on the use of own fodder, and (b) organic rearing using free range and own organic fodder. An emergy approach was applied in this analysis. Comparison of different production systems using emergy analysis made it possible to show the scale of environmental resource commitment for baseline and scenario-based productions, and to determine the amount of renewable and non-renewable emergy consumed per unit of production. Through the use of selected emergy indicators, e.g.: Environmental Loading Ratio (ELR), Emergy Yield Ratio (EYR), the environmental impact for each case was determined. For the ecological system scenario, the need to change production parameters (stocking rate, maximum poultry house area, free range) was taken into account. The results of the emergy-based indicators showed that the baseline production places the greatest burden on the environment and is the least sustainable. The organic system is the opposite; however, due to production limitations and the lower production efficiency achieved, it may not be economically viable to orient a farm exclusively to the organic system. In an environmental assessment, the information obtained can provide valuable guidance to agricultural producers. They can help make informed decisions on natural resource management to achieve environmental security. The results are also important for political decision-makers in creating policies for more sustainable agricultural production. The results obtained are discussed, pointing out the importance of the analysis used mainly from an environmental point of view.

Recommended Strategies Based on The Capability And Purchasing Power of Low-Income Communities (MBR) In Providing MBR Houses In Kartamantul

The housing needs that shape urban spatial structures or the relationships between the three cannot be fully understood without considering the state of housing market prices. The reason is that changes in urban housing market prices no longer depend on the city level, but over time begin to be characterized by urban agglomeration processes. Furthermore, agglomeration dynamics that change urban spatial structure and housing market prices will have an impact on socio-economic disparities and challenges in providing affordable housing for people with low incomes in densely populated urban areas. The aim of this research is to find out whether the MBR housing allocated by the regional government is appropriately located in low-income areas/zones in KARTAMANTUL. The research methods used are web scrapping, mapping and comparative evaluation of housing locations with the distribution of MBR in KARTAMANTUL. The results obtained were to simplify the simulation of affordability and household purchasing power regarding home ownership, the researchers tried to average the income of the two categories of low-income households. Therefore, with an average MBR income limit of Rp. 3,900,000 in DIY, then the ability to repay the house in installments is IDR. 1,170,000/month. Furthermore, regarding house buildings, the criteria for a habitable house is a per capita area of at least 9 m2 per person. With the average number of family members in DIY being 4 people, the house area required per household is 36 m2. The recommendations given are a) 25 year house installments are a payment option that can be used for low-income households in KARTAMANTUL, b) the choice of house locations for MBR is mostly in Bantul Regency and Sleman Regency, both of which have urban status. fringe and urban shadow.

The Impact of Real Estate Purchase Restriction Policy on Urban Economic Development—A Case Study of Beijing

Since 2010, Beijing's purchase restriction policy has been adjusted several times to adapt to the market and promote stability. In April 2024, the policy was eased for housing areas outside the Fifth Ring Road, marking the first major adjustment in 13 years. This paper analyses the economic impact of Beijing's real estate purchase restriction policy, focusing on its effect on investment, consumption, industrial structure, and employment. The study indicates that the purchase restriction policy initially hinders investment and consumption in the short term but contributes to market stability and industrial optimization in the long run. The policy change has increased housing sales and growth in related industries outside the Fifth Ring Road, promoting economic development in the suburbs. Furthermore, the policy has a nuanced impact on the employment market, encouraging labor mobility toward high-tech and service industries while affecting employment in real estate-related sectors. The study suggests that policymakers need to consider the impacts of various aspects to ensure the healthy development of the real estate and employment markets.

Comparative Analysis Between Self-management and Contractual System in Banjarmasin-banjarbaru Areas Housing Project (Reviewed from the Quality, Time, and the Customer Satisfaction Projects)

The success of implementing housing projects can be seen from the system used as a measure of the success of implementing housing projects. The performance of the housing project implementation project consists of several aspects, among others, can be viewed from the aspects of quality, time and customer satisfaction. The housing project implementation system in Indonesia generally tends to use a self-managed system and a contractual system. The method used in this research is descriptive analytic by using data collection through questionnaires and interviews. The research was conducted on 19 subcontractors with the same type of housing and structure in the Banjarmasin-Banjarbaru housing area. Processing and data analysis were carried out in several stages, namely validity and reliability testing, descriptive analysis and research hypothesis testing using the Independent Sample T-Test. The results obtained from the quality aspect obtained a significant value resulting from the difference test of 0.026 (p <0.05) that there is a significant comparison between the self-managed system and the contractual system in terms of quality aspects. The result of the Mean Difference value from the quality aspect is 6.90. From the time aspect, the significant value generated from the difference test is 0.06 (p> 0.05), so it can be concluded that there is no significant comparison between the self-managed system and the contractual system in terms of time. The result of the Mean Difference value from the time aspect is 5.14. The aspect of customer satisfaction obtained a significant value resulting from the difference test is 0.001 (p <0.05), so it can be concluded that there is a significant comparison between the self-management system and the contractual system in terms of customer satisfaction aspects. The result of the Mean Difference value from the aspect of customer satisfaction is 2.89. It can be concluded that in terms of quality, time, and customer satisfaction, self-managed systems have a higher average value than the contractual system. Keywords: Self-management systems, Contractual systems, Quality and Time Aspects, Customer satisfaction project

Impact of Race and Culture Assessments (IRCAs) in combatting anti-Black racism and reducing recidivism

The Gladue report, named after R. v. Gladue, is a landmark Supreme Court of Canada case which emphasizes the need to consider unique circumstances faced by Indigenous individuals when determining appropriate sentences. Given the overrepresentation of Black identities at all levels in the justice system, it is argued that the use of pre-sentencing reports referred to as Impact of Race and Culture Assessments (IRCAs), also needs to be comprehensively implemented for Black offenders in Canada. IRCAs are pre-sentencing reports that help sentencing judges better understand the effect of poverty, marginalization, racism, and social exclusion on the offender and their life experiences, and how those factors inform the circumstances of the offender, the offence committed, and the offender’s experience with the justice system. This is significant as it goes beyond a one-size-fits-all punitive justice system that has been ineffective in reducing recidivism. By recognizing the intersections of race, culture, and justice, IRCAs enable judges to make more informed decisions contributing to an equitable consequence for the accused. More importantly, we argue that the insights from IRCAs should be used to connect offenders with culturally reflective wraparound social services upon return into the community to address the root causes in areas of employment, education, and housing that gravitate people towards criminality. By acknowledging historical and systemic biases and tailoring supports to individual identities, life experiences, and community conditions, IRCAs have the potential to transform the criminal justice system through promotion of alternatives to custody that correlates with reductions in recidivism.

The Effects of Sound Absorption of Stage House on the Acoustics of Auditorium in an Opera House

The coupling effects between the stage house and the auditorium in opera houses make the sound field very complex. In the present study, the effects of stage absorption on the primary monaural objective room acoustic parameters in the seating area of an opera house in China were investigated by means of computer simulation and scaled model measurement. In computer simulations, the absorption coefficient of the ceiling and walls of the stage house was changed across several steps, and then a series of experiments were conducted in a 1:20 scaled hall with and without curtains and wall absorption on the stage to verify the simulation results. It was found that stage absorption has a significant influence on early decay time (EDT), reverberation time (RT) and clarity (C80) in the seating area, while the effect on sound strength (G) is much smaller. The values of EDT and RT decrease with an increase in sound absorption on the stage, while C80 displays an opposite trend. In addition, when the average absorption coefficient of the stage walls and ceiling is over 0.5, the variations in these four parameters due to the increase in stage absorption can be constrained within an acceptable range.

Barriers to financial access of disabled people to health services in rural areas: A case study of Iran.

People with disabilities (PWDs) account for a significant percentage of the world's population, with a higher prevalence in less developed countries. Access to healthcare services is the main component of health systems performance, with lower access for PWDs living in rural areas. The current study aimed to investigate PWD's access to healthcare services in rural areas of Iran and, secondly, factors that contribute to this issue. Following a cross-sectional design, the current descriptive-analytical study is performed in the north of Iran. Using the quota sampling technique, 471 PWDs were recruited. Data were collected using a valid and reliable questionnaire, covering three dimensions of access, by face-to-face interview. Data analysis was administered using central tendency indicators and multiple regression by SPSS version 17. Statistical significance was considered when the P value <0.05. The mean score of PWD's access to healthcare services for dimensions of utilization, availability, and affordability was 8.91 (±6.86), 14.54 (±2.3), and 51.91 (±8.78), indicating very low, low, and moderate levels of access. All three regression models were significant (P < 0.05), and variables of gender, age, marital status, education level, residence status, the income of the household head, receiving financial aid, and house area showed a significant effect (P < 0.05). This study demonstrated the seriousness of paying attention to PWD's financial access to healthcare services, particularly in rural areas of Iran. Hence, policymakers should better focus on this problem, mainly regarding accessibility and utilization and factors that result in inequalities.

M-W 모형 비교분석과 수도권 주택수요 추정 - 선형·비선형·가구기반 모형을 중심으로

This study aims to derive a housing demand analysis model suitable for the changing population and household structure. To this end, the modified M-W linear model, modified M-W non-linear model, and modified M-W household-based model were estimated using the 2010 MDIS housing survey data. The models were tested against the total housing area in 2021 from the Population and Housing Census to validate them in an out-of-sample spirit. The models were also used to estimate the long-term housing demand in the Seoul metropolitan area up to 2030. The analysis results suggest that the household-based M-W model can be best used to estimate housing demand when the number of households is growing rapidly compared to the number of people and household characteristics are dominant. Still, the population and household structure are changing, so an appropriate housing demand analysis model should be used depending on the time.

A threat analysis for the world’s most threatened turtle (Rafetus swinhoei)

We conducted a comprehensive threat analysis of the Swinhoe’s softshell turtle (Rafetus swinhoei), the most endangered freshwater turtle in the world, historically occurring along river systems in Vietnam and China, but currently almost extinct. Here, our goal was to identify the pressures along two main rivers in Vietnam (Black and Red rivers, both extending into Yunnan, People’s Republic of China), building a conceptual framework to understand the causal relationships among driving forces, threats, and the target species. We involved a panel of experts who identified two priority direct threats in Vietnam, classified following the IUCN standard taxonomy, and showing the highest Magnitude (as a proxy of threat pressure): (i) Habitat loss at nesting sites (LOS; code 1.2 - Commercial & industrial areas) and, (ii) Land conversion due to settlements (LAN; code 1.1 - Housing & urban areas). Threats showed a comparable (i.e., not significantly different) Magnitude in the two rivers (Mann-Whitney U test). Experts also identified the underlying driving forces behind these threats: (i) demographic drivers (due to a rapid population growth in the last decades) causing LAN and LOS, as the priority threats, but also sand mining, and water pollution; (ii) economic drivers induced by high poverty in local populations and causing harvesting (fishing activities and related markets), the needs of power supply for economic activities (e.g., dams), and recreational activities; (iii) ethical drivers linked to conservation project teams (limited funds and divergent points about strategies to carry out). Preliminary data for China suggest HAR (Harvesting by native fishers; code 5.4) and POL (water pollution; code 9.2) as priority threats. Threat analysis is an useful tool in the early stages of a conservation project during the context analysis, helping to define priorities for conservation and management.

Motivators and barriers of ulam consumption among residents from low-cost housing areas in Kuala Lumpur

PurposeUlam is a traditional salad that contains high levels of antioxidants and is commonly consumed in raw form. However, the average ulam consumption among the low-income Malaysian population was only ½ serving daily. Thus, this study aimed to explore the motivators and barriers to ulam consumption among residents of low-cost housing areas (household income RM4849 or $1015.50) in Kuala Lumpur, Malaysia.Design/methodology/approachSix focus group discussions were conducted with 27 Malay residents aged 18–59 years in Kuala Lumpur, Malaysia. The researchers asked the participants a series of semi-structured questions. All the interviews were audio-recorded and transcribed verbatim. Two researchers coded the transcripts independently, and several themes were identified. The data were analysed using Nvivo version 12 software.FindingsThree main factors for ulam consumption were identified in this study: personal, environmental and behavioural. The motivators and barriers were identified based on nine main themes and 16 sub-themes.Practical implicationsThe results of this study identified potential areas for an effective intervention to increase ulam intake among residents in low-cost housing areas.Originality/valueThis work has the potential to identify the factors that have an impact on consumers' ulam preferences to help fulfil daily vegetable recommendations.

Happiness and air quality: microdata analysis in Indonesia

BackgroundWhile economics is growing in Indonesia, its Happiness Index remains steady. Regarding the average concentration of dissolved particles, Indonesia is ranked sixth globally. Many factors can affect happiness. Environmental conditions, especially air quality, are considered to influence individual happiness. Therefore, this research investigates the impact of air quality and health on happiness.MethodsData used in this study is the microdata of Indonesia’s Happiness Survey (SPTK) in 2021. With more than 70,000 respondents, the study uses Ordered Probit as an analysis method with subjective happiness as the dependent variable. The independent variables used in this study are air quality, age, gender, housing area per capita, marital status, and health status. All independent variables except age are categorical. The variable of interest, air quality, is coded “1” if the IKU achieves the Strategic Plan’s target of 84.2 and “0” otherwise. IKU is a regional air quality index that combines two substances.ResultsAt a significance level of 5%, there is a positive relationship between subjective happiness and air quality. In other words, if air quality (IKU) meets the Strategic Plan target (≥ 84.2), then a person is more likely to have a higher level of happiness. It can be explained more with the marginal effect. The marginal effect concludes that if the target is achieved, the probability of having a lower level of happiness decreases by up to 2.8%, and a very high level of happiness rises by 5.1%. Regarding health status, the rarer someone gets sick, the happier she/he is.ConclusionThe study finds that air pollution could lower happiness, while better health increases happiness. Therefore, it is important to meet the target of IKU and to improve public health. Some good practices can be adopted to achieve this goal.

Agricultural landscape composition alters ant communities in maize fields more than plant diversity enrichment

Abstract. Pasaribu DN, Rizali A, Tarno H, Priawandiputra W, Johannis M, Buchori D. 2024. Agricultural landscape composition alters ant communities in maize fields more than plant diversity enrichment. Biodiversitas 25: 205-213. Fragmented natural habitats in human-modified landscapes play a crucial role in conserving biodiversity. Ants, as keystone species, are integral to terrestrial ecosystems, making it essential to comprehend the factors influencing their survival. This study investigates the impact of agricultural landscape composition and plant diversity enrichment (flowering plants) management on shaping ant communities in maize (Zea mays L.) fields. The research occurred in maize fields surrounded by other crops, semi-natural habitats, and housing areas in Malang District, East Java, Indonesia. The four agricultural areas were divided into control and treatment plots, considering landscape composition parameters, particularly Class Area (CA) and the Number of Patches (NP), measured within a 500 m radius. The landscape around the maize fields was characterized by manually digitizing land use. Six types of plant diversity enrichment were employed in this study: wild cosmos (Cosmos caudatus), white buttercup (Turnera subulata), sunflower (Helianthus annuus), long bean (Vigna unguiculata), ornamental bean (Arachis pintoi), and coral vine (Antigonon leptopus). The study was divided into the dry season (April-July 2022) and the wet season (September-December 2022). Ant sampling was conducted using pitfall traps and, based on generalized linear models, revealed that plant diversity enrichment management did not affect species richness, abundance, or composition of ants. Landscape composition positively influenced ant species richness but negatively impacted species composition, particularly the number of semi-natural habitat patches. Maize crop age also positively influenced ant species richness but negatively affected beta diversity. Wet season was also found to have a negative effect on beta diversity. In conclusion, the proportion of semi-natural habitats in agricultural landscapes and crop age contribute significantly to species richness and species composition of ants.

Heterogenous treatment effects of a voluntary Inclusionary Zoning program on housing prices

Housing affordability remains a social and economic issue in New Zealand. Affordability policies such as Inclusionary Zoning have been promoted to streamline land delivery and boost the housing supply. This paper takes the Special Housing Areas (SHA) programme implemented in Auckland, New Zealand, as a case of a voluntary IZ, and explores the effects on the distribution of housing prices. We rely on a Difference-in-Difference framework as the general identification strategy to estimate quantile treatment effects. We use about 175 thousand sales transactions between September 2011 and September 2016. Considering all transactions, the results show that the SHAs program failed to reduce housing prices across the distribution; and, even in some cases, prices increased. We also find that, for new dwellings, the program decreased prices at the lower end of the distribution while increasing them at the upper end. We argue that the mechanism driving these results is the construction of larger dwellings in the upper part of the distribution. As the SHAs did not involve a mandatory mechanism for affordability purposes, we argue that non-affordable dwellings were built and delivered in the first place with the added price premium of a streamlined delivery. Therefore, as an example of a voluntary IZ program, the SHAs may have stimulated supply, but numerous implications arise as improvements in affordability are negligible or questionable.

GA-BP based daylight prediction and sensor placement in residential areas

This paper conducts a comprehensive analysis of the light environment in different areas of residential houses located in Beijing’s Guangyuanli neighborhood. The main objective of this study is to assess the contribution of natural daylight to residential illuminance, with the aim of providing a foundation for reducing energy consumption and enhancing light comfort. While previous research predominantly focused on sensor deployment in single scenes such as offices and classrooms, these approaches are inadequate for multi-scene analysis of daylight in residential areas. Moreover, traditional deployment methods can negatively impact the quality of life and everyday living experience. To overcome these limitations, a prediction model is developed to estimate ceiling and window illuminance, as well as work surface illuminance in various scenes within residential buildings. The Dialux software is employed for data simulation, and a GA-optimized BP neural network is utilized to train the model, establishing the mapping relationship between input variables and corresponding illuminance outputs. By inputting sensor values from different scenarios into the model, the predicted daylight illuminance values can be obtained. This predictive approach facilitates the evaluation of light comfort and energy consumption reduction in different functional areas of residential buildings.
