Alternative investments and Financial technology (FinTech) businesses’ recent entry and quick expansion of new financial services have propelled banking institutions into operational innovation to secure sustainable competitive advantage. Recent increases in the number of academic articles devoted to the strategic facets of asset management were stimulated by significant changes in such a competitive environment. Organizations begin to understand that a strategic approach to asset management becomes a source of long-term survival in an unstable environment and sustained competitive advantages. This study reviewed trendy financial issues: alternative investments, Robo-advisor-based asset management, and related service research in the finance and financial engineering field from the perspective of the aforementioned financial service environment.

본 연구의 목적은 청소년들의 스마트폰 과의존과 피로회복 간의 관계에서 불안의 매개효과를 검증하여, 청소년의 스마트폰 과의존 중재의 근거자료를 확보하는 것이다. 연구 대상자는 ‘제16차 청소년 건강행태 온라인조사’를 이용한 청소년 54,948명이다. 연구변수 간의 관계는 상관분석, 요인분석, 매개효과 분석을 실시하였다. 연구 결과 청소년의 스마트폰 과의존은 피로회복에 영향을 미치는 직접효과와, 불안을 경유하여 피로회복에 영향을 주는 간접효과가 나타났다. 청소년의 스마트폰 과의존이 매개변인인 불안에 유의한 영향을 주었고, 피로회복에 유의한 영향을 주었다. 또한 또한 불안은 스마트폰 과의존과 피로회복 간의 관계에서 매개효과가 있는 것으로 확인되었다. 따라서 스마트폰 과의존 청소년을 대상으로 피로회복 을 향상하기 위해 불안을 관리할 필요가 있다.

This study investigated the association between dietary intake and 10-year risk for CHD predicted from Framingham risk score in Korean adults using the Korea National Health and Nutrition Examination Survey 2019-2020. Eight thousand subjects (3,382 men and 4,618 women) aged 30 years or older were classified into three groups according to the 10-year CHD risk (%). The sociodemographics, anthropometrics indices, blood profiles, and dietary intake were collected. After adjusting for confounding variables, the mean adequacy ratio (MAR) decreased for both men and women as the disease risk increased. The high–risk group was below the MAR criteria, indicating that the overall quality of the meal was not good. The highest consumers of legumes (OR 0.56, 95% CI 0.37-0.84), fruits (OR 0.67, 95% CI 0.48-0.93), and fish (OR 0.60, 95% CI 0.42-0.87) had a 44%, 33%, and 40% lower 10-year CHD risk than lowest consumers in men, respectively. In women, there is no significant relationship between food groups and disease risk. Therefore, improving lifestyle habits such as weight control, increased activity, and adequate food intake, especially legumes, fruits, and fish rich in antioxidant nutrients and bioactive substances, appears to have a potential association with preventing coronary heart disease in Korean adults.

Levels of beauvericin (BEA) and enniatins (ENNs: ENA, ENA1, ENB, and ENB1) were examined in fresh ginger (n = 43) and ginger powder (n = 31) samples from Korea. In the ginger samples, incidence of BEA contamination was highest, at 62.79%, with a maximum detected BEA level of 640.07 μg/kg. ENNs in were found in up to 11.63% (ENB, ENB1) of ginger samples, with a maximum detected level of 91.02 μg/kg (ENA). In the ginger powders, ENB contamination displayed the highest rate of incidence (70.97%), but the highest level of BEA (1,344.18 μg/kg) exceeded that of ENB (413.99 μg/kg). The incidences of ENA, ENA1, ENB, and ENB1 presence in ginger powders were 29.03%, 22.58%, 70.97%, and 35.48%, respectively, and their highest detected levels were 220.45, 156.61, 413.99, and 70.29 μg/kg, respectively. The incidence of BEA and ENN contamination was higher in ginger powder than in ginger. Respective co-occurrence rates of BEA and ENNs in ginger and ginger powder samples were 16.28% and 64.52%, indicating that the BEA and ENN co-contamination rate was highest in ginger powder as well. This is the first report on the presence and co-occurrence of BEA and ENNs in Korean ginger and ginger powder.

This study was performed to assess the cosmic-ray effect caused by altitude in the aerial gammaray measurement. For the gamma-ray measurement experiment by altitude, the aerial survey system composed of four 4×4×16 inches large volume NaI (Tl) detectors was used. The aerial survey system was installed in a rotor-craft to stably keep its flight altitude and position. In addition, in order to avoid to time-dependent shielding effects with the amount of fuel, a rotor-craft of which the fuel tank is not located beneath the cabin floor was selected. In this study, the ROI (Region Of Interest) was set to the 3~6 MeV range to assess the cosmic-ray contribution to the gamma-ray spectrum that could ignore the contribution of the dominant natural radionuclides. The gamma-ray spectra measured inside and outside of the rotor-craft on the ground were compared to evaluate the shielding effects of the aircraft body. As a result, the count rate of the 40K photo peak was decreased by about 10% when measuring the inside compared to the outside. On the other hand, the total count rate of the 3~6 MeV region was decreased by about 0.7% under the same condition. Therefore, the aircraft body effect was insignificant in 3~6 MeV region considering the relative uncertainty of 0.04~0.78% (1σ). In addition, the count rate in the 3~6 MeV range according to altitude was evaluated to assess the cosmic-ray effect. In order to evaluate the change in the ROI count rate according to the altitude, the gamma-ray spectrum was measured in the range of 300~2,000 m above the sea to avoid the effect of terrestrial radiation. As a result, the relationship between altitude and count rate in the 3~6 MeV range showed a high correlation with the R2 value of 0.99, when the approximate equation was derived in the form of a quadratic polynomial. Also, the count rate of 3~6 MeV at 50~500 m above the ground was estimated using the correlation equation, and this value was compared with the measured count rate. As a result of comparing the average value of estimated count rate and measured count rate, the relative difference is less than 2%. Considering the relative uncertainty of 0.78~4.11% (1σ), it was possible to evaluate the count rate of the 3~6 MeV region relatively accurately. The results of this study could be used for further study on background dose corrections in aerial survey.

The 2-round Delphi survey and Focus Group Interview (FGI) survey method, in this study, are sequentially applied for the level analysis of the high-level radioactive waste (HLW) management technologies, that are classified into transport/storage, site evaluation, and disposal categories. The 2- round Delphi survey was conducted on domestic 56 experts in the HLW field in Korea, and survey answers were managed with questionnaires distributed by e-mail. In the FGI survey, domestic 24 experts from management field were formed into three groups to conduct in-depth interviews. Past research achievements including journal papers, intellectual properties and the expert opinions presented at expert hearing on HLW technology were used as reference materials. As a result of the survey, in this study, the average domestic technology level compared to the leading countries was 83.1% in transport area, 79.6% in storage area, 62.2% in site evaluation area, and 57.4% in disposal area, respectively. When compared to the former level analysis results in 2017, technology level of transport-storage area increased by 8.6%, and the site evaluation-disposal technology area decreased by 7.27%. The highest factor that increase the level of technology in the transport-storage field was due to the increased R&D program resulting on journal papers, intellectual properties. In addition, the decrease factor in the level of technology in the site evaluation-disposal field was mainly due to relatively low R&D program when compared to the leading countries. Suggested method for the level survey can be used to find out the basic data of the lower tech technologies, to estimate the efficient research budgets and to prepare the R&D human resources. With this regards, R&D roadmap can be matured with suggested prediction method for the domestic technology level on HLW.
