The experiment was carried out to determine the concentration of vitamin A by Carr-Price reaction ot fifty six sera obtained from normal cows and fourty four sera from the cows with ovarian hypofunction. The results obtained in this work were summerized as follows: 1. The mean values of vitamin A concentration of sera obtained from the cows with ovarian hypofunction were 88 IU/100 ml in summer (grazing), and in winter 79 IU/100 ml (hay) and 173 IU/100 ml (trench silage). The mean values of vitamin A concentration of sera from normal cows were 212 IU/100 ml in summer (grazing), and in winter 113IU/100 ml (hay) and 338IU/100 ml (trench silage). The differences of the concentrations of vitamin A among three groups were statistically highly significant (p<0.01). 2. The differences of vitamin A concentrations between the hay group and the trench silage group in normal cows and in cows with ovarian hypofunction were statistically highly significant (p<0.01). 3. The concentrations of vitamin A in summer group (grazing) were higher than those of the hay group in winter in normal cows and in cows with ovarian hypofunction. 4. The concentrations of vitamin A in the trench silage group in winter were higher than those of summer group (grazing) in normal cows and in cows with ovarian hypofunction.

Referring to Buyer's obligations, the Buyer must pay the price for the goods and take delivery of them as required by the contract. There are vital importances to the Buyer's Fundamental Breach. The legal effects of a breach of contract do not depend on the nature of the obligation broken, but on the consequences of the breach the detriment to the other party. The obligations mentioned to Article 53 are primary obligations which are to be fulfilled in the normal performance of the contract. They include a number of different acts which could be seen as the subject-matter of different obligations. CISG gives further details for the payment of the price in Articles 54 to 59 and for taking delivery in Article 60. The buyer has to take delivery at the respective place within a reasonable period after this communication since he cannot be required to take delivery immediately. Refusing to take delivery in case of delay not constituting a ground for avoiding the contract makes no sense, since this would lead to even later delivery. For the understanding of Buyer's Fundamental Breach, We need to search the Cases referring to the breach of buyer's main obligations.

Investors have increasingly become interested in macroeconomic antecedents in order to better understand the investment environment and estimate the scope of profitable investment in equity markets. This study endeavors to examine the interdependency between the macroeconomic antecedents (international oil price (COP), Domestic gold price (GP), Rupee-dollar exchange rates (ER), Real interest rates (RIR), consumer price indices (CPI)), and the BSE Sensex and Nifty 50 index return. The data is converted into a natural logarithm for keeping it normal as well as for reducing the problem of heteroscedasticity. Monthly time series data from January 1992 to July 2019 is extracted from the Reserve Bank of India database with the application of financial Econometrics. Breusch-Godfrey serial correlation LM test for removal of autocorrelation, Breusch-Pagan-Godfrey test for removal of heteroscedasticity, Cointegration test and VECM test for testing cointegration between macroeconomic factors and market returns,] are employed to fit regression model. The Indian market returns are stable and positive but show intense volatility. When the series is stationary after the first difference, heteroskedasticity and serial correlation are not present. Different forecast accuracy measures point out macroeconomics can forecast future market returns of the Indian stock market. The step-by-step econometric tests show the long-run affiliation among macroeconomic antecedents.

Developing countries have faced serious difficulties in implementing customs procedures. For example, they have experienced heavy administrative constraints such as lack of qualified personnel and non-computerization. Some importers in developing countries have tried to undervalue or overvalue the imported goods and misclassify them with the target of lowering the incidence of customs duties. In order to address these problems many of developing countries often require the exporter to get a Clean Report of Findings(CRF) issued by a preshipment inspection entity. This study tries to reply to the following questions with which the exporters are faced in the process of issuance of CRF. First, what are the provisions and regulations that the exporters have to note in the event a CRF is issued by the inspection entity? Second, how do the exporters safeguard their own rights in case of price verification? Third, how to protect the confidential business information to be submitted by the exporters in order to get a CRF? Fourth, how can the exporters respond to the improper conducts that the inspection entities have done?

Some multi echelon inventory systems carry perishable products. The value of these product reduces as the period of time they spend in the system. In this paper We derive the necessary condition to determine optimal quantity, service level for a perishable product. The systems considered consist of two echelons and carry single item. To determine the optimal order quantity, the demand is assumed to be constant, the holding costs may be different in the echelons, and it allows no shortages. I assumed the price of product decreases by negative exponential function. To determine service level, following assumptions used in the model ㆍlead time is constant. ㆍdemand is normal distribution. ㆍthe product starts to perish at the second echelon. Service level is computed for different levels of lead times and for different variance of demands and for different price functions. The experimental results indicate that the service level in cost is a function of service level in demand and perishability of product. Results of the models exhibit that perishability and the age of the product are critical to determine the lot sizing and service level.

The purpose of this study is to measure the agricultural product market efficiency of the three e-commerce platforms from the perspective of consumer price fairness perception, analyze the quality and price gap of invalid brands, and help agricultural products enterprises to formulate reasonable price strategies. The characteristics of farm products sold in e-commerce platforms(quality, origin, taste, safety level) were selected as output indicators and the prices of products were selected as input indicators to evaluate the efficiency of the market through DEA analysis. According to the analysis, JD mall has the largest proportion of effective brands, while YHD.com has the highest average market efficiency, and northeast rice has the largest difference in average efficiency among the three platforms. The results show that price inefficiencies still exist in the electronic market. The development of online market for agricultural products should pay attention to consumer price fairness and pay attention to the coordination between price and quality. The limitation of this paper is that it does not focus on the influence of words of mouth marketing in internet market and consumer experience, which can be the future research direction.

The purpose of this study was to analyze and consumption patterns diet/low-calorie food. Ubjects were 353 adult women aged 20s~50s. Ubjects were divided into three groups according to body mass index (BMI): Normal group (BMI>23.0), overweight group (23.0${\leq}$BMI<25.0), and obesity group (BMI${\geq}$25.0). This study collected all information by self-administrated questionnaires. The SPSS version 21.0 was used for analysis of data. The obesity group lower education level (p<0.001), higher age (p<0.001) and higher income (p<0.001) than normal group. However, score of health status was highest in normal group (p<0.001). Proportion of obesity group pill type diet/low-calorie (p<0.034), drug (diuretic, appetite suppressant and riental medicine) (p<0.001), and cosmetic surgery (p<0.001). The main reason for consumption of diet/low-calorie was control without starving (28.0%). Obese group emphasized manufacturer, ingredient and reputation, whereas the normal group emphasized price and expected effectiveness (p<0.001).

In this study, to capture the skewness and kurtosis detected in both conditional and unconditional return distributions of the stock markets of Kazakhstan and Russia, two versions of normal mixture GARCH models are employed. The data set consists of daily observations of the Kazakhstan and Russia stock prices, and world crude oil price, covering the period from 1 June 2006 through 1 March 2021. From the empirical results, incorporating the long memory effect on the returns not only provides better descriptions of dynamic behaviors of the stock market prices but also plays a significant role in improving a better understanding of the return dynamics. In addition, normal mixture models for time-varying volatility provide a better fit to the conditional densities than the usual GARCH specifications and has an important advantage that the conditional higher moments are time-varying. This implies that the volatility skews implied by normal mixture models are more likely to exhibit the features of risk and the direction of the information flow is regime-dependent. The findings of this study contain useful information for diverse purposes of cross-border stock market players such as asset allocation, portfolio management, risk management, and market regulations.

The purposes of this paper were to identity the present condition of the imported fashion luxury brands' market arid to analyze the differences of marketing strategies according to the types of retailers. We selected 3 department stores, 5 luxury brands, 5 stores in Dongdeamun Market, and 5 internet luxury shopping malls, and conducted key informant survey to 20 experts. The brands in department stores consisted the goods according to VIPs' pre-orders, sales of the previous year, and fashion trends, and offered the differentiated customer services to VIPs. The stores in Dongdaemun Market bought the products from the parallel importers or imported the goods from the original nations of the brands by themselves. The goods in stock and steady sellers were comprised of the main portion of all products, and leather goods were dominated. The price of goods in stock was about $30\∼50\%$ lower than the normal price of department stores, but the new products' price was only about 10$\%$ lower than that of department stores. Luxury shopping malls could be classified into two types; one conducted both product buying and commission sale, and the other conducted commission sale only. In former case, however, the product buying portion was under 30$\%$. Product assortments and the price strategy were similar to the stores of Dongdeamun Market, and CRM was conducted partially.

This study estimated the long-run and the short-run price and income elasticity of crude oil demand by using the ARDL model in Korea. First, the long-run cointegration relationship existed between crude oil demand and price or income in the ARDL-bounds tests. Second, the long-run own price, the cross price elasticity and the income elasticity were both statistically significant elastic and sensitive in the ARDL. Third, there was autocorrelation of the residuals, but no misspecification errors and heteroscedasticity, and then the residuals showed a normal distribution. And the CUSUM & CUSUMSQ tests showed that the coefficients were stable. Fourth, the short-run own price, the cross price elasticity and the income elasticity were both statistically significant elastic and sensitive in the ARDL-RECM. The ECM with the short-run dynamics showed rapid adjustments in the long-run equilibrium of oil demand after the economic crisis. In the short-run, the sensitivity of crude oil demand to price and income changes has moved in the same direction as the long-run case. Korea, depending too much on foreign crude oil, is vulnerable to the shocks of oil prices, so rising oil prices can certainly have a negative impact on Korea's trade balance. And the elasticity of long-run oil prices may help to control and manage Korea's oil demand. The government needs to strengthen monitoring of the country's policies and market trends related to crude oil, establish strategies to customize national policies and market conditions, and strengthen active market dominance efforts through pioneering new market and diversification.
