Ya-Hao LI(Ya-Hao LI),Fan YANG(Fan YANG),Shuang ZHANG(Shuang ZHANG) 한국웰빙융합학회 2024 웰빙융합연구 Vol.7 No.1
Purpose: The improvement of the social security system can greatly affect residents' future uncertainty, and it is important to study the relationship between public pensions and household consumption. Research design, data and methodology: Using the 2018 China Household Panel Survey (CFPS) data, the instrumental variable method is used to analyze the impact of pension insurance on urban residents' consumption. Results: The results of the study show that there are differences in the impact of three different pension insurance systems on household consumption. The pension insurance for public sector significantly boosts household consumption, and having a pension insurance for public sector can increase household consumption by 7.7%. The pension insurance for enterprise employee will reduce household consumption, but this is only significant for urban households. The pension insurance for urban and rural residents has a negative impact on household consumption. For the 16- to 39-year-old group, having a pension insurance for urban and rural residents will reduce household consumption by 5.7%. At the same time, household income, assets, scale, and education level will positively stimulate household consumption. Conclusions: The study reveals varying impacts among different pension types, highlighting the need for optimizing social security schemes to incentivize higher consumption rates.

Radiation therapy is an important treatment for head and neck squamous cell carcinoma (HNSCC). However, how to promote radiation sensitivity in HNSCC remains a challenge. This study aimed to investigate the radiosensitizing effects of fenofibrate on HNSCC and explore the underlying mechanisms. HNSCC cell lines CNE-2 and KB were subjected to ionizing radiation (IR), in the presence or absence of fenofibrate treatment. Cell growth and survival, apoptosis and cell cycle were evaluated. In addition, CNE-2 cells were xenografted into nude mice and subjected to IR and/or fenofibrate treatment. The expression of cyclinB and CDK1 was detected by Western blotting. Our results showed that fenofibrate efficiently radiosensitized HNSCC cells and xenografts in mice, and induced apoptosis and G2/M arrest via reducing the activity of the CDK1/cyclinB1 kinase complex. These data suggest that fenofibrate could be a promising radiosensitizer for HNSCC radiotherapy.

As a form of overseas consumption in international education service trade, international student education is an important emerging industry today, and also an important boost for South Korea in the field of foreign investment and trade. Driven by South Korea's promotion of studying abroad in South Korea to the national strategic level, the scale of studying abroad in South Korea has shown a trend of rapid development. At the same time, South Korea's export trade has entered an important development period of industrial structure upgrading. In the context of globalization, a correct understanding and analysis of the impact of education in South Korea on South Korea's export trade will help improve the quality and efficiency of South Korea's export trade. This paper adopts the empirical analysis method to find out the impact of overseas education in South Korea on export trade ,and puts forward two assumptions to conduct a comprehensive discussion. From the empirical results, in general, the education of foreign students will significantly promote the expansion of South Korea's export trade. When dividing the scale, the regression results show that the countries with large scale of students studying in South Korea each year have a positive impact, while the countries with small scale do not have a significant impact. In the future, South Korea can further promote the construction of the brand of "studying in South Korea" in international education cooperation, improve talent attraction policies, and develop bilateral friendly diplomatic relations, so as to promote the development and upgrading of international talent inflow and South Korea's export trade.
Seismic Response Analysis Method for Lining Structure in Underground Cavern of Hydropower Station
Hao Zhou,Ming Xiao,Yang Yang,Guoqing Liu 대한토목학회 2019 KSCE Journal of Civil Engineering Vol.23 No.3
Based on the analysis of joint shear test, the complex shear strength model of the interface between surrounding rock and lining structure, considering the interfacial bonding characteristics, shear failure mechanism and seismic dynamic deterioration effect, is established. And based on the dynamic contact force method, the dynamic calculation method of contact surface is presented, which is suitable for the dynamic analysis of the contact system between surrounding rock and lining of underground powerhouse. Then the dynamic numerical simulation method for the lining structure of underground powerhouse is formed by coupling the complex shear strength model with the dynamic calculation method of the contact surface. By using this method and based on the independently developed dynamic calculation platform of underground powerhouse, the evolution process and characteristics of seismic damage of lining structure of Yingxiuwan underground powerhouse are studied. At the same time, the numerical simulation analysis is carried out on the vibration damping measures of the lining structure. The results shows that the dynamic numerical simulation method for lining structure is effective and reasonable. In addition, the idea on the aseismic design of lining structure of underground powerhouse is put forward.

The red palm weevil (RPW), Rhynchophorus ferrugineus, is an important pest of palms, and difficult to control by conventional methods. Therefore, microbial control is an alternative strategy for controlling RPW. Herein, a total of 15 entomopathogenic fungi (EPFs) were subjected to primary pathogenicity screening against last stage of RPW larvae. The preliminary data showed that four Beauveria bassiana isolates (JEF-484, 158, 462 and 507) and one Isaria fumosorosea isolate (JEF-014) resulted in 100 % mortality within 5–10 days post inoculation (d.p.i.), respectively. According to the time required for RPW mortality, JEF-484, 158, 462 and 014 were further sub jected to bioassays using 10 7 conidia/ml suspensions by spraying method. Based on the results, JEF-484 showed the highest mortality and shortest LT 50 on the last stage of RPW larvae, followed by JEF-158. The two isolates also showed good conidial production and high thermal stability compared to the other isolates. Therefore, JEF-484 and JEF-158 were selected for bioassays against RPW egg and the last larval stage with different concen trations of 10 5 , 10 6 and 10 7 conidia/ml conidial suspensions by spraying method. For the bioassay at the egg stage, JEF-158 showed a significantly higher ovicidal effect than JEF-484. In the larval bioassay, both EPF isolates showed a dosage-dependent effect on the RPW larvae. JEF-484 caused higher mortality in RPW larvae than JEF-158. In summary, the combination of the 2 promising EPF isolates might provide an opportunity for the practical microbial control of RPW at different life stages in palm tree fields.

The objective of this study was to assess the effects of constant high ambient temperatures on meat quality, antioxidant capacity, and carnosine expression in longissimus dorsi muscle of finishing pigs. Castrated 24 male DLY (crossbreeds between Landrace${\times}$Yorkshire sows and Duroc boars) pigs were allocated to one of three treatments: constant ambient temperature at $22^{\circ}C$ and ad libitum feeding (CON, n = 8); constant high ambient temperature at $30^{\circ}C$ and ad libitum feeding (H30, n = 8); and constant ambient temperature at $22^{\circ}C$ and pair-fed with H30 (PF, n = 8). Meat quality, malondialdehyde (MDA) content, antioxidant capacity, carnosine content, and carnosine synthetase (CARNS1) mRNA expression in longissimus dorsi muscle were measured after three weeks. The results revealed that H30 had lower $pH_{24h}$, redness at 45 min, and yellowness at 24 h post-mortem (p<0.05), and higher drip loss at 48 h and lightness at 24 h post-mortem (p<0.01). Constant heat stress disrupted the pro-oxidant/antioxidant balance in longissimus dorsi muscle with higher MDA content (p<0.01) and lower antioxidant capacity (p<0.01). Carnosine content and CARNS1 mRNA expression in longissimus dorsi muscle of H30 pigs were significantly decreased (p<0.01) after three weeks at $30^{\circ}C$. In conclusion, constant high ambient temperatures affect meat quality and antioxidant capacity negatively, and the reduction of muscle carnosine content is one of the probable reasons.

The hot syndrome refers to any feverish conditionsduring a pathological development, a sub-healthphenomenon, and is a potential risk for human health. Themetabonomics study on the hot syndrome may provideinsight into understanding of its pathology and play a rolein the prevention and treatment of its related diseases. Inthis paper, the rats were dosed with the hot syndromeprescription, ginseng and water. The corresponding urinesamples were identified by rapid resolution liquid chromatographycombined with quadrupole time-of-flight tandemmass spectrometry. More than 1,000 metaboliccompounds from different urine samples could be furtherdifferentiated by principal component analysis. As a result,the rat body temperature and weight were recognized as thehot syndrome related factors. Some specific metaboliteshave been discovered as a pattern of the potential biomarkers for the hot syndrome. The results showed thatginseng cannot cause the hot syndrome in a reasonabledose, but the hot syndrome prescription can. It is suggestedthat ginseng cannot be used only as a tradition Chinesemedicine but also as a nutrient. The work showed metabonomicsmethod is a valuable tool in studying mechanismof the hot syndrome.
