This study identified the severity of youth gambling behavior and analyzed the impact of stress, impulsivity, peer attachment and social interest on youth gambling behavior. Based on the results of the study, the government sought to help understand teenagers who are addicted to gambling and to help them maintain psychological and social stability and healthy living. A total of 237 high school students were surveyed. According to the analysis, the prevalence rate was found to be 3.4 percent of the problem gambling group and 9.3 percent of the medium-risk gambling group, and a total of 12.7 percent was addiction. Low-risk gambling groups accounted for 16.9 percent and non-problem gambling groups accounted for 70.5 percent. By gender, male students have more serious gambling problems than female students. As a result of dividing the group that experienced gambling more than once and the group that did not experience gambling into gambling group and non-gambling group, the two groups showed significant differences in impulsiveness, avoidant attachment, and interest in others. Furthermore, a correlation analysis was conducted to examine the relationship between these factors and the level of gambling behavior, showing that only impulsivity was significant.

The implications of bank-specific risks and macroeconomic risks on the growth, profitability, and stability of Islamic and conventional banks are examined and compared in this article. The study also investigates whether corporate governance mitigates the effects of both bank-specific and macroeconomic risks on Islamic and conventional banks' development, profitability, and stability. For the period 2007-2019, we examined a panel data set of 22 banks in Pakistan, including both Islamic and conventional banks. We discovered considerable evidence that both bank-specific risks and macroeconomic risks have negative effects on the growth, profitability, and stability of Pakistani banks using a dynamic panel data estimator, the two-step Generalized Method of Moments (GMM) approach. Furthermore, the findings show that bank-specific and macroeconomic risks have different consequences in both types of banking. The impacts of liquidity risk, operational risk, capital risk, inflation risk, and exchange rate risk are higher for Islamic banks than for conventional banks. Conventional banks, on the other hand, are more vulnerable to credit risk and interest rate risk. Finally, the findings show that good corporate governance reduces the negative consequences of both categories of risks on bank development, profitability, and stability. This is true for Islamic and conventional banks alike.

The process of implementing risk management systems for the organizations in financial service industry can be viewed as a diffusion of innovation since the introduction of the risk management systems changes the decision making process on risks faced by the organizations. The purpose of the reported research is to examine the factors that affect the successful implementation of ALM(asset & liability management) systems, the risk management systems managing interest rate risk. Specifically, this paper presents an investigation of three factors from the diffusion of innovation studies; internal factors, external factors, and time. A field survey was conducted for Korean banks that have implemented ALM systems. The results suggest that the perceived uncertainty of market, system supports, and management supports be most significantly related to the successful implementation of the risk management systems. The findings of the current study also suggest a certain amount of time should be passed to diffuse the risk management systems in organizations.

We investigate the appropriateness of the fixed 12% discount rate to be used in estimating the amount of compensation for revoking a license for fishery business by the Enforcement Decree of Fisheries Act in Korea. We also suggest the appropriate discount rate fully reflecting the change of market interest rate in the Korean financial market. The capital asset pricing model, or, CAPM is the best known model of risk and return, and is widely used to estimate the expected rate of return for the risky projects. Even though the CAPM implies that the discount rate or the expected rate of return should change as the related market factors do, the discount rate used to estimate compensation for revoking a license for fishery business remains to be the same 12% rate for the last 15 years by law. During this period, however, the yield to maturity for the 5-year government bonds in Korea has dramatically changed from about 12% to less than 3%. In order to provide the fair compensation for the damages against the coastal fisheries and evaluate the intrinsic value of fishery resources in the coastal areas, we suggest that the appropriate discount rate should be determined by the yield to maturity of the government bonds with 5-year maturity, instead of the current fixed 12% interest rate.

The study aimed to study the effect of the inflation rate, the real domestic product, the interbank lending interest rate, and the total deposits on credit facilities in Jordan for 2012-2021 through quarterly data. The study adopted the ARDL model. The study used the time series analysis method, as the study tests the stationarity of the time series. The results showed that the impact of inflation on the total credit facilities was negative. In contrast, the impact of each of the total deposits, real GDP, and the interest rate of interbank loans on the total credit facilities was positive and significant. The study recommended the need for the banking sector in Jordan to develop risk management mechanisms in a way that allows it to adapt to economic cycles and crises by conducting stress tests and developing scenarios that ensure the formation of sufficient provisions to meet emergencies. The study also recommended that the macroeconomic policy should be based on creating a stable macroeconomic environment that allows the efficient employment of resources in all economic sectors in a way that achieves high economic growth rates, which contributes to the promotion of economic recovery and is reflected in income. Hence, individuals have a greater ability to repay loans.

Lithium-ion batteries (LIBs) have attracted much interest for their high energy density (>150 mAh/g), high capacity, low self-discharge rate, and high coulombic efficiency. However, with the successful commercialization of LIBs, fire and explosion incidents are likely to increase. The thermal runaway is known as the major factor in battery-related accidents that can lead to a series of critical conditions. Considering this, recent studies have shown an increased interest in countering the safety issues associated with LIBs. Although safety standards for LIB use have recently been formulated, little attention has been paid to the safety around the manufacturing process for battery products. The present study introduces a risk assessment method suitable for assessing the safety of the LIB-manufacturing process. In the assessment method, a compensation parameter (Z-factor) is employed to correctly evaluate the process's safety on the basis of the type of material (e.g., metal anode, liquid electrolyte, solid-state electrolytes) utilized in a cell. The proposed method has been applied to an 18650 cell-manufacturing process, and three sub-processes have been identified as possibly vulnerable parts (risk index: >4). This study offers some crucial insights into the establishment of safety standards for battery-manufacturing processes.

This study aimed to suggest an alternative income generation (AIG) for local artisanal fisheries communities in the southern coastal area of Bangladesh, which is vulnerable to climate change. To analyze the problems of local artisanal fisheries caused by climate change, field surveys and in-depth interviews with fishermen and government officials were conducted. Livelihood risk factor (LRF) in the marine fishing sector included reduction of fishing days and fish production and damage to fishing vessels and fishing gear due to cyclone and sea-level rise. LRF in the aquaculture sector included cultured fish escape, reduction of aquaculture production, and water pollution due to Monsoon flood. A common challenge for two sectors was high interest rate on commercial loans. Small-scale tank aquaculture is recommended as AIG for securing income of artisanal fisheries communities. In the early stages of dissemination of small-scale tank aquaculture technology, it is necessary to prevent fishermen from struggling to repay high-interest rate loans through technology transfer and facility support by official development assistance. The aquaculture training center, along with the technical education, will also contribute toward expansion of local distribution network and marketing support to establish a value chain for local artisanal fisheries communities.

생명보험의 보험료는 보험가입자들의 예정 수명분포와 예정 이자율에 기초하여 산출되게 된다. 산출된 보험료는 향후 해당 보험을 운영하는 과정에서 발생할 수 있는 보험회사나 보험가입자들의 손실 그리고 이들이 부담하는 리스크에 직접적인 영향을 미치게 된다. 따라서 생명 보험에서 이들 두 가지 요소, 즉 예정 수명분포와 예정 이자율은 중요한 영향 변수로 여겨진다. 본 논문에서는 종신보험에서 이들 영향 변수가 보험료, 보험 운영상의 리스크, 보험운영에 있어서의 손실 확률에 미치는 영향력을 분석하고 상대적인 영향력의 크기를 비교해 보고자 한다.

본 연구의 목적은 위험을 반영하여 지역별 아파트 투자성과를 분석하고 지역별 특성의 존재유무를 검증하는 것이다. 분석을 위해 지역별 아파트 투자성과를 장단기로 나누어 분석하였다. 자료수집기간은 2002년부터 2012년의 10년간이며 대상지역은 서울의 강남 북과 6개 광역시이다. 성과평가를 위해 만기 5년의 국민주택1종 채권수익률을 무위험수익률로 사용하고 임대수익계산을 위해서는 만기1~2년 정기예금금리를 사용하였다. 분석결과, 장기투자성과 시에는 서울과 인천은 지역특성이 존재하지 않아 트레이너지표를 사용하여 평가하였으며 지방광역시는 지역특성이 존재하여 젠센지표로 평가하였다. 또 단기성과평가시에는 모든 지역에서 지역특성이 존재하는 것으로 나타나 젠센지표를 사용하여 평가하였다. 모든 지역에서 지역특성이 작용하는 단기 성과평가 결과는 단순수익률로 평가한 결과와 전혀 다른 것으로 나타났다. 따라서 단순 수익률로 성과평가를 할 경우에는 성과에 대한 인식을 왜곡할 수 있음이 드러났다.
