Weather condition has effect on traffic condition, but there is a lack of research between weather and traffic condition. So, in this study analyzes speed variation according to rainfall intensity in national highway provincial road. The results of the analysis, average speed is reduced about 3.2%. But average speed decrease by maximum 8.8% when traffic volume is below 200vph per direction. Because relatively, free flow traffic speed has greatly deceased according to rainfall intensity in provincial road. Also in this study estimates of speed reduction model according to rainfall and performs the statistical verification. Estimated speed reduction model's slops are gradual when rainfall increased, because average speed is reduced by rainfall when free flow.

This study examined the effects of apios (Apios americana Medikus) supplementation on visceral obesity in high-fat diet-induced obese mice. C57BL/6N mice were fed a high-fat diet (40% calories from fat) with or without apios powder (10%, w/w) for 12 weeks. At the end of the experiment, apios supplementation reduced visceral fat mass significantly by 14.3% compared to the control group. Apios decreased significantly the atherogenic index, serum leptin level, hepatic lipid (free fatty acid and triglyceride) content, and lipid droplets, whereas it increased the serum high density lipoprotein-cholesterol/total cholesterol ratio. Hepatic lipogenic gene expression of peroxisome proliferator activated receptor gamma, fatty acid synthase, and diacylglycerol O-acyltransferase 2 was down-regulated by apios supplementation. These results suggest that apios is a healthy food for preventing high-fat diet-induced visceral obesity and fatty liver.

For the purpose of improving storability and process adaptability of potato, we carried out an experiment to investigate the effects of microwave heating on the total lipid content and fatty acid composition of the potatoes in storage. The samples were made by powdering potatoes exposed to the microwave energy in a 560W, 2,450MHz oven for 0, 60, 120 and 180 seconds respectively. From the examination of the samples stored at th temperature of $25{\pm}1^{\circ}C$ for 12 months, the following results were obtained. As an over-all tendency, the longer the samples were heated and the longer they were stored, the total lipid content decreased but the microwave-heated samples showed decreasing rates less than those of the controls for the whole storage periods. As major fatty acids of the potato flour, linoleic acid (30.92 %), palmitic acid (29.34 %), linolenic acid (8.90 %) and stearic acid (8.23 %) were detected from the samples. The longer the samples were exposed with microwave, unsaturated fatty acids like 18:2, 18:3 increased. generally with the lapse of storage time, saturated fatty acids increased while unsaturated ones decreased. But in the samples heated with microwave, we observed an apparent suppression of the increasing rate of the saturated fatty acids and the decreasing rate of the unsaturated fatty acids, and the suppressing effects turned out to be proportional to the length of microwave heating.

Purpose: Obesity has emerged as a critical global public health concern as it is associated with and increases susceptibility to various diseases. This condition is characterized by the excessive enlargement of adipose tissue, primarily stemming from an inequity between energy intake and expenditure. The purpose of this study was to investigate the potential of sweet pumpkin powder in mitigating obesity and metabolic disorders in leptin-deficient obese (ob/ob) mice and to compare the effects of raw sweet pumpkin powder (HNSP01) and heat-treated sweet pumpkin powder (HNSP02). Methods: Leptin-deficient obese mice were fed a diet containing 10% HNSP01 and another containing 10% HNSP02 for 6 weeks. Results: The supplementation of ob/ob mice with HNSP01 and HNSP02 resulted in decreased body weight gain, reduced adipose tissue weight, and a smaller size of lipid droplets in the adipose tissue and liver. Furthermore, the ob/ob-HNSP01 and ob/ob-HNSP02 supplemented groups exhibited lower levels of triglycerides, total cholesterol, low-density lipoprotein cholesterol, fasting blood glucose, and insulin, as well as a reduced atherogenic index in comparison with the control group. Molecular analysis also demonstrated that the intake of HNSP01 and HNSP02 resulted in a diminished activation of factors associated with fatty acid synthesis, including acetyl-CoA carboxylase and fatty acid synthase, while concurrently enhancing factors associated with lipolysis, including adipose triglyceride lipase and hormone-sensitive lipase, in the adipose tissue. Conclusion: Taken together, these findings collectively demonstrate the potential of sweet pumpkin powder as a functional food ingredient with therapeutic properties against obesity and its associated metabolic disorders, such as insulin resistance and dyslipidemia.

This study was designed to investigate the possibility of the use of dried mackerel, which is enriched with docosahexaenoic (22:6n-3, DHA) and eicosapentaenoic (20:5n-3, EPA) acids, as a means of increasing the intake of these n-3 polyunsaturated fatty acids, and to investigate the effect of the consumption of mackerel on tissue triglyceride, cholesterol contents and fatty acid compositions. Twenty male mice were fed on 5% palm oil (control group) and 5% dried mackerel (mackerel group) diets for four weeks. Total triglyceride, cholesterol and LDL-cholesterol levels tended to decrease in serum, heart and kidney of the mackerel group compared to the control group, while HDL-cholesterol levels were increased with the intake of mackerel. In fatty acid compositions of serum and heart, the mackerel group showed increased percentages of n-3 fatty acids, especially DHA and EPA, and decreased percentages of arachidonic (20:4n-6, AA) and docosapentaenoic (22:5n-6, DPAn-6) acids compared to the control group (p<0.05). There was a similar tendency in kidney and adipose tissue but AA levels were not significantly different between the control and mackerel groups. These results indicate that intake of dried mackerel as the n-3 vehicle for increasing tissue n-3 fatty acids may be associated with improvement in lipid metabolism.

노년기에 들어서더라도 신체가 요구하는 기본적인 영양소는 변하지 않지만 열량 요구는 감소된다. 이는 젊었을 때보다 활동량이 적어지는 노년기의 환경적 원인과 함께 체질량 감소 및 상대적으로 증가하는 지방세포 때문이다. 지방세포는 비지방세포와 비교해 늦게 대사되며 칼로리도 신속히 소모되지 않는 특징이 있다. 노인일수록 모든 영양소를 골고루 섭취하되 열량은 줄이는 식습관을 형성하는 것이 중요한 이유가 여기에 있다.

The goal of this study was to evaluate the anti-obesity effect of radish leaf extracts (MU-C) and radish leaf extracts with 3% citric acid (MU-CA) in a high-fat diet (HFD)-induced C57BL/6 mice. The effects of radish leaf extracts on adipogenesis were also investigated using 3T3-L1 adipocytes. As determined by Oil red O staining, MU-C inhibited adipogenesis in 3T3-L1 adipocytes. Four-week-old male C57BL/6 mice were fed an HFD for 6 weeks and then treated with radish leaf extracts (500 mg/kg, p.o.) for 6 weeks. Then, the serum levels of Aspartate aminotransferase, Alanine aminotransferase, Total cholesterol, Triglyceride and low-density lipoprotein cholesterol in the mice were measured using an automatic chemical analyzer and enzyme-linked immunosorbent assay. Administration of MU-C significantly reduced the fat weight when compared with HFD controls. As confirmed by histopathologic analysis, adipose tissue size markedly decreased in mice treated with MU-C. Therefore, this study could provide a basis for investigating the clinical use of MU-C as an agent for preventing obesity.

This paper studies the logic of fiscal constraints and fiscal autonomy in a political agency model with both moral hazard and adverse selection. The electoral process not only disciplines incumbents who may act against the public interest but also opts in politicians who are most likely to act along voters' interests. We characterize perfect Bayesian equilibria under shared tax system and fiscal autonomy with fiscal constraints for local public good provision. It is shown that the local voters' expected welfare under fiscal autonomy is higher than under shared tax system if the same fiscal constraints are applied. In order to examine the effects of party's candidate selection processes on the behavior of local politician and national politician, we extend the model to an environment where local politician can compete for the candidacy of national assembly with incumbent national politician. If local politician wins majority of votes against incumbent national politician, then he can move on to serve as a national politician. Otherwise, his political career will end as a local politician. It is the gist of this primary system portrayed by this setup that local politician and national politician compete to garner more votes. Therefore, primary system as a candidate selection mechanism enhances local residents' welfare compared to top-down candidate selection processes.
