In the current technology-driven era, Small and medium enterprises (SMEs) have been deemed as one of the leading and prominent drivers of sustainable economic progress in emerging and developing economies such as in the Bangladesh context. Hence, it is of significance to understand what might fuel accelerating performance of SME business as increased SME performance will bring about more sustainability and strong development of SME sector within the country, through which more employment is anticipated to be generated. Therefore, the current study examines the impact of three factors: risk-taking, innovativeness, and proactiveness on SME performance in Bangladesh. The study has gathered data from SME entities in Dhaka city of Bangladesh, by applying a non-probability sampling strategy. 250 SME owners were contacted to act as respondents and finally, 180 SME owners fully completed the survey questionnaire, indicating that the final sample size is n=180. SPSS is used as a purpose of testing the hypotheses by considering a 5% significance level as acceptance criteria of the hypothesis. Hierarchical regression analysis was run to understand the impact of control variables and independent variables on SME performance and found that age of business, risk-taking, innovativeness, and proactiveness have an important impact on SME performance in Bangladesh.

Recently, social technologies have been created to solve problems from businesses for the establishment of generational solidarity ecosystem in terms of employment, residential space, network and social capital, age, cognitive and environmental aspects. This is senior-friendly healthcare business system aimed at meeting the senior needs for health life to enjoy active consumption culture life even after retirement, becoming a catalyst for minimizing generational conflicts, preventing the cognitive and physical deterioration of seniority in the areas of life healthcare, fitness and well-aging, and expanding into systems necessary for seniority self-reliance. We would like to draw up the development and requirements of the concept of the service platform for the study of collective characteristics for generation solidarity with senior class and the establishment of a customized senior health life system for generation solidarity. This system is characterized by a platform that can prevent the decline of seniors' cognitive and physical functions and enhance emotional stability. It is significant in providing feedback on the risk perception index, fall index, and prevention training index information to the child through the analysis and extraction of the senior health index for risk perception, fall probability, and fall prevention.

In Bangladesh, developing students' entrepreneurial intentions have received a lot of attention because of the country's current employment predicament and shifting labor market. Entrepreneurs play a critical part in a country's economic development. This study aims to examine the impact of creativity and innovation on students' intentions toward online entrepreneurship in Bangladesh. The participants in this study were Bangladeshi university students. Based on pre-tested constructs, a survey questionnaire was created. Convenience sampling, which is a common type of non-probability sampling, was used to choose participants for the sample. A total of 150 students from the public university took part in the survey, with 120 replies being accepted as complete, resulting in an 80 percent response rate. Hence, the sample size is 120. Internal consistency was determined using Cronbach's alpha, while correlation and hypothesis tests were analyzed using SPSS version 26.0. The results reveal that creativity and innovation have a statistically significant and positive impact on students' intentions to engage in online entrepreneurship. These two independent factors explained 75% of the variance in intention to engage in online entrepreneurship, resulting in empirical findings and solid information in the present body of knowledge. The study concludes with a conclusion and research implications for the future.

The purpose of this study was to identify the relationship among financial debt burden, psychological factors and financial stress. Data was collected by surveying 450 individuals who were over twenty years old, and 384 were used for the analysis. As the result, first, number of sources of debt, use of each debt, marital status/double income, housing, debt amount and financial stress were found to be significantly different among three groups(debt free, non risky, risky). In addition, marital status/double income, gender, housing and income were found to significantly influence to the probability of being one of the three groups. Second, level of debt burden, age, employment and income were found to significantly influence to financial stress, while psychological factors such as risk tolerance and self-control were not. It might be noteworthy that people in debt were likely to have higher level of stress, while the older, employed, and having higher income were likely to have lower level of stress. This study would provide useful information in terms of debt policy to relieve the financial stress.

본 연구는 여성관리자패널조사(Korean Women Manager Panel)를 이용하여 한국 여성 근로자의 직장 내 스트레스 및 승진에 상사의 성별이 미치는 영향을 분석한다. 분석결과 직속 상사가 여성일 때 여성 근로자의 직장 내 스트레스는 높았고, 사원 및 대리 직급 여성의 승진에 부의 영향을 미치는 것으로 나타났다. 여왕벌 현상과 역할일치이론에 따르면 한국과 같이 유리천장이 견고하고 상위 직급의 남성 밀집도가 높은 구조에서는 여성 리더십의 긍정적인 특성이 발휘되기보다 다른 여성에 대해 높은 인정 기준을 요구하거나 경쟁적인 모습을 보여 여성 상사를 둔 여성 근로자의 직장 내 스트레스는 높고 낮은 직급의 여성 승진확률은 낮추는 것으로 해석할 수 있다.

The demand of large capacity in coming cellular systems makes inevitable the deployment of small cells, rendering more frequent handoff occurrences of calls than in the conventional system. The key issue is then how effectively to reduce the chance of unsuccessful handoffs, since the handoff failure is less desirable than that of a new call attempt. In this study, we consider the control policies which give priority to handoff calls by limiting channel assignment for the originating new calls, and allow queueing the new calls which are rejected at their first attempts. On this system. we propose the problem of finding an optimal call control strategy which optimizes the objective function value, while satisfying the requirements on the handoff/new call blocking probabilities and the new call delay. The objective function takes the most general form to include such well-known performance measures as the weighted average carried traffic and the handoff call blocking probability. The problem is formulated into two different linear programming (LP) models. One is based on the direct employment of steady state equations, and the other uses the theory of semi-Markov decision process. Two LP formulations are competitive each other, having its own strength in the numbers of variables and constraints. Extensive experiments are also conducted to show which call control strategy is optimal under various system environments having different objective functions and traffic patterns.

본 연구는 2010년 조기재취업수당 제도 변화 전후의 수급자 특성을 살펴보고, 실업자 재취업 촉진에 대한 성과 변화를 살펴본다. 조기재취업수당 수급자에 대한 특성 분석 결과, 제도 변경 이후로 여성 및 고령층의 수급확률이 증가하고 중졸 이하 저학력층의 수급확률이 증가하였다. 이는 실제 수혜집단이 취업 애로계층으로 다소 전환되어 노동시장 취약집단의 취업촉진이라는 조기재취업수당의 정책 목표에 보다 근접해졌음을 시사한다. 제도 변경전 후의 재취업률과 재취업된 일자리 유지율을 비교한 결과, 재취업률에는 큰 변화가 없어서 수급요건 강화로 인한 구직자의 재취업 유인 감소 효과가 크지 않은 것으로 판단된다. 이와 더불어, 조기재취업수당 수급자의 재취업 일자리 유지율은 제도 변화 이후 높아진 것으로 나타났다.

I employ search-and-matching to a multi-country and multi-sector Ricardian model with input-output linkages, trade in intermediate goods, and sectoral heterogeneity, in order to quantify the welfare effects from tariff changes. The paper shows that labor market frictions can be a source of comparative advantage in the sense that better labor market conditions contribute to lower cost in production. Labor market frictions play a critical role in determining the probability of exporting goods to trading partners, and interact with bilateral trade share, price, expenditures, etc. Unemployment and changes in unemployment rates due to tariff reductions contribute welfare changes across countries, implying that welfare effects based on quantitative trade models with full-employment are likely to be biased. I confirm the biased welfare effects by revisiting Caliendo and Parro (2015), who conduct an analysis of the welfare effects from the NAFTA from 1993 to 2005. I show that the welfare gap between theirs and mine has a positive correlation with changes in observed unemployment rates across countries. With the constructed model, I further conduct counterfactual exercises by asking what would happen if China's tariffs remain unchanged from 2006 to 2015. It turns out that there are mild welfare effects to trading partners in the world trading system.
