This paper is an exploratory study about perceived risks related to career women's fashion lifestyles in case of catalogue shopping. Three research questions are proposed: 1. The first is to examine the types of career women's fashion lifestyles. 2. The second is to find out the kinds of perceived risks when career women purchase fashion apparels through catalogues. 3. The third is to investigate the relationships between fashion lifestyles and perceived risks. The empirical results were as follows. First, career women's fashion lifestyles were distinctively divided into the fashion-oriented group, the casual preference group, and the brand-name preference group. Second, seven unique perceived risks such as socio-psychological perceived risks, product assortment perceived risks, quality/function perceived risks, customer services & conveniences perceive risks, economic perceived risks, and order waiting-time perceived risks were manifested when career women purchase fashion apparels using catalogues. Finally, significant differences in socio-psychological perceived risks, product assortment perceived risks, and quality/function perceived risks were shown among fashion lifestyle clusters. However, the others were not.

The building construction projects include a variety of risk factors due to uncertainties. To succeed in the projects, it is important how risks are managed. Risk management is composed of identification, analysis and response. Especially, the risk analysis is important to objectively calculate significance of risk factors. This paper evaluates a method to find priorities of risks using the AHP(Analytic Hierarchy Process). The method has some defects; (1) the consistency becomes weak as the number of pair-wise compared risks is large, and (2) the input and output procedures are complex when risks are added to or removed from a risk database. Thus the paper adopt the PROMETHEE(Preference Ranking Organization METHod Enrichment Evaluations) analysis process which is able to overcome the limitation of the AHP restricted to 9 risk factors. The PROMETHEE method makes the procedure of risk analysis simple, when the risk factors pull out and put in the risk database. The purpose of this study is to prove the possibility of the PROMETHEE analysis process by being compared with AHP.

This paper investigates the relationship between the spread of COVID-19 and time preference. In contrast to previous studies that compared time preferences before and during the pandemic, this study estimates time preferences during the COVID-19 period using eight surveys conducted over two years. Additionally, a regression analysis was conducted on the number of new COVID-19 cases and the time elapsed since the outbreak, with estimated time preference as the dependent variable. Despite a small sample size, statistically significant results were obtained, showing that as the number of new cases increased, time preference also increased. However, this effect diminished over time and disappeared by the end of 2021 in Japan. This may be due to the public's growing familiarity with the risks of COVID-19 and the availability of vaccines and treatments. Despite a significant increase in new cases in 2022, time preference was lower than immediately after the outbreak, and this was reflected in private investments. Immediately after the outbreak of COVID-19, private investments decreased by 12% compared to the previous year, but the investments are returning in 2022 despite the surge in the number of cases. The trend of time preference explains the trend of Japanese private investments very well.

Financial literacy is one of the sustainable development goals of huge concern of governments. Governments explore solutions addressing policies to improve financial literacy. Nevertheless, financial management has such a broad scope and is not just limited to knowledge. As human nature, individuals are born with different confidence levels that include various financial abilities. This study aims to investigate the household-financial efficacy through the application of psychometric instruments, risk preference, and demographic characteristics toward consumption decision behavior. The research is based on a survey 479 households in the peninsular Malaysia, and utilizes the structural equation model, cluster proportional and systematic random sampling, and two measurements - composite reliability and average variance extracted. Results show that households' financial efficacy is one of the critical factors that explain the households' consumption decision behavior. Also, risk preference, gender and area location (rural or urban) of the household determined the consumption decision behavior of the household. The effectiveness of consumption decision is not only determined by financial literacy, but also financial efficacy. The implications of this paper may help to design policies in narrowing the broad gap between the rural and urban level of financial efficacy. The government needs to take appropriate actions to fix it.

BACKGROUND/OBJECTIVES: This study evaluated whether a mobile health (mHealth) application can instigate healthy behavioral changes and improvements in metabolic disorders in individuals with metabolic abnormalities. SUBJECTS/METHODS: Participants were divided into an mHealth intervention group (IG), which used a mobile app for 24 weeks, and a conventional IG. All mobile apps featured activity monitors, with blood pressure and glucose monitors, and body-composition measuring devices. The two groups were compared after 24 weeks in terms of health-behavior practice rate and changes in the proportion of people with health risks, and health behaviors performed by the IG that contributed to reductions in more than one health risk factor were analyzed using multiple logistic regression. RESULTS: Preference for low-sodium diet, reading nutritional facts, having breakfast, and performing moderate physical activity significantly increased in the mHealth IG. Furthermore, the mHealth IG showed a significant increase of eight items in the mini-dietary assessment; particularly, the items "I eat at least two types of vegetables of various colors at every meal" and "I consume dairies, such as milk, yogurt, and cheese, every day." The proportion of people with health risks, with the exception of fasting glucose, significantly decreased in the mHealth IG, while only the proportion of people with at-risk triglycerides and waist circumference of females significantly decreased in the control group. Finally, compared to those who did not show improvements of health risks, those who showed improvements of health risks in the mHealth IG had an odds ratio of 1.61 for moderate to vigorous physical activity, 1.65 for "I do not add more salt or soy sauce in my food," and 1.77 for "I remove fat in my meat before eating." CONCLUSIONS: The findings suggest that the additional use of a community-based mHealth service through a mobile application is effective for improving health behaviors and lowering metabolic risks in Koreans.

Existing Android malware detection approaches mostly have concentrated on superficial features such as requested or used permissions, which can't reflect the essential differences between benign apps and malware. In this paper, we propose a quantitative calculation model of application risks based on the key observation that the essential differences between benign apps and malware actually lie in the way how permissions are used, or rather the way how their corresponding permission methods are used. Specifically, we employ a fine-grained analysis on Android application risks. We firstly classify application risks into five specific categories and then introduce comprehensive risk, which is computed based on the former five, to describe the overall risk of an application. Given that users' risk preference and risk-bearing ability are naturally fuzzy, we design and implement a fuzzy logic system to calculate the comprehensive risk. On the basis of the quantitative calculation model, we propose a risk classification based approach for Android malware detection. The experiments show that our approach can achieve high accuracy with a low false positive rate using the RandomForest algorithm.

Construction contracts involve the allocation or distribution of the risks inherent to a construction project between or among contracting parties. However, it has been a common practice that only one party drafts the contract due to practical reasons and particular policies of various organizations. Interviews were conducted on some local contractors to gain their meaningful insights and standpoints on the allocation of each risk. These results were compared with the actual risk allocation using the Philippine government standard contract and risk principles from the literature to determine if their considered opinions provide a plausible alternative. A sample application of this evaluation is presented for construction-related risks and risk allocation recommendations are provided in the end.

최근 건설 프로젝트는 규모의 대형화, 공정의 복잡함 등에 의한 리스크 인자의 발생이 증가하고 있다. 이로 인해 건설관리에서 리스크 관리의 중요성은 더욱 부각되고 있는 현실이다. 리스크 관리는 확인, 분석, 대응의 과정을 통해서 이루어지며, 분석과정에서 위험인자들의 중요도 및 우선순위를 객관적이고 정확하게 분석해내는 것이 리스크 관리의 성공여부를 좌우한다. 본 연구는 기존연구에서 건설 프로젝트의 공정 리스크 중요도 및 우선순위를 산출하는데 사용된 AHP 기법의 문제점을 보완하기 위하여 PROMETHEE를 활용한 정량적 분석 프로세스를 제시하였다. PROMETHEE를 사용함으로써 AHP 기법에서 분석대상 인자가 9개를 초과 할 때의 신뢰성 저하와 인자의 추가 또는 삭제 시 발생하는 복잡한 산출절차의 문제점을 보완할 수 있을 것으로 기대된다.
