  • The objective of this study was to develop a stock that can be used to make a variety of dishes. For this, stock was prepared with beef, chicken, and pork meat as animal meats as well as anchovy, mushroom, and sea tangle as other ingredients. The qualities of six[only four though] kinds of stocks made with beef only (B), beef and chicken (BC), beef and pork (BP), and beef added with chicken and pork (BCP), and seven kinds of stocks made with anchovy (A), mushroom (M), sea tangle (S), anchovy and mushroom (AM), anchovy and sea tangle (AS), mushroom and sea tangle (MS), and anchovy added with mushroom and sea tangle (AMS) were investigated by sensory evaluation. The most preferred stock made with animal meat was mixed with the most preferred stock made with other ingredients at a 5% level to test the synergistic effects of palatability. As a result, BCP stock and AMS stock obtained the highest scores for overall preference. BCP stock within the range of 30%-65% along with the mixed stock containing AMS (35%-70%) showed synergistic effects for palatability.

  • This study analyzed how interdependence between China, Hong Kong, Taiwan and Singapore stock markets changed after the implementation of Shanghai-Hong Kong Stock Connect system using the EGARCH-GED model that allow simultaneous analysis of return and variability. Since the implementation of this system, the interdependence of Taiwan stock market with the Greater China stock markets has been weakened, and the interdependence of Singapore's stock market with the Greater China stock markets has not been exist. On the other hand, he interdependence between China and Hong Kong stock markets has been shown to be significantly enhanced since the implementation of this system. This is appears to be the result of improved conditions for Chinese and Hong Kong investors to invest in the two stock markets following the implementation of this system. Thus, considering the portfolio investment in the Greater China stock markets, the investors will need to develop their investment strategies in light of these facts that the weakening interdependence of the Taiwan and Singapore securities markets and the strengthening interdependence of the Chinese and Hong Kong securities markets.

  • As economic activities decrease, and the stock market decline due to COVID-19, many people are jumping into stock investment as an alternative source of income. As people's interest increases, many stock price analysis studies are underway to earn more profits. Due to the variance observed in the stock markets, it is necessary to analyze each stock independently and consistently. To solve this problem, we designed and implemented models and services that analyze stock prices using a reinforcement learning technique called Asynchronous Advantage Actor-Critic(A3C). Stock market data reflected external factors such as government bonds and KOSPI (Korea Composite Stock Price Index) as well as stock prices. Our proposed work provides a web service with a visual representation of predictions of stocks and stock information through which directions are given to investors to make safe investments without analyzing domestic and foreign stock market trends.

  • Seolleongtang, a traditional broth in Korea, is expected to become a hot global item for its unique flavor and healthiness. In this study, the correlations between sensory attributes and physicochemical characteristics were studied for the popular seolleongtang stock products through descriptive analysis, sensory evaluation and analysis of salt, soluble solid, protein, viscosity and color for the quality control. Our results indicate that color, concentration, viscosity, and freshness are important attributes in evaluating the quality of seolleongtang stock. There were significant differences between preference and sensory attributes among the stock products. Significant correlations were found between flavor and texture and overall acceptability, as well as beany odor and aroma. Preference and physicochemical aspects also correlated, and indicate that a range of salt, solubility, and viscosity are applicable as quality control factors in seollengtang stock.

  • Woolen fabrics were manufactured in Korea since the early prehistoric period and were manufactured and used from the period of the three Kingoms and Koryo through the Chosonera. These materials were developed in to woolen fabrics through a tradition of thou-sand years. In Korea the Orient Culture of no-madic tribes and Mesopotamia Culture of stock-farming come together and developed these original woolen fabrics cultures. During the Chosen period woolen goods were frequently manufactured and used. Those re-mains consist of various hats and shoes made up of felt. And the remains which of a kind of woolen fabrics were made from the wool materials. There were various stock farms and supplies a woolen craftsman needed the wool materials.

  • In order to understand the effect of introduction of oyster rack culture on natural short-necked clam, Ruditapes philippinarum, stock, we investigated the status of natural clam stock prior to introduction of oyster rack culture at Yeongheung Coast of Wando Island. The growth equation of the clam was estimated as: $L_t=61.46{\cdot}(1-e^{-0.172(t+0.155)})$ from ring radius composition of shell. Instantaneous coefficient of total mortality and natural mortality were calculated as: 2.4087/year and 0.478/year, respectively. The age at first capture was estimated to be 2.55 year. The total biomass was estimated to 3.23 ton in the bed (0.8 ha). Applied by these parameters, the annual recruit biomass and the current yield per recruit (Y/R) was corresponded to $114.7individuals/m^2$ and $92.0g/m^2$, respectively. Maximum sustainable yield (MSY) was estimated 0.77 ton/year which was close to annual catches, 0.74 ton/year, in the area.

  • Lactobacillus sp., Acetobacter sp. and yeast were the most dominant organisms in the EM stock culture and subculture product. Lactic acid bacteria and yeast were able to grow in the fermentation process utilizing seawater. EM treatment of higher concentrations using EM stock culture and EM clay balls (1% or 4%) contributed to an early removal of malodor and an increase of DO in the polluted sediments, indicating an odor-removing activity of EM. The EM treatment of higher concentrations (1% or 4%) somewhat appeared to modify the microbial communities within the sediments, which was confirmed by existence of a few unique fragments from the stock culture based on PCR-DGGE. It still remains to be elucidated that EM cultures were directly involved in the malodor removal and potential sediment bioremediation.

  • The purpose of this paper is to reveal two problems in the existing inventory systems in retail market, and to suggest a Two-Bin System under Automatic Ordering System considering only base-stock. Large retailers already have a sophisticated inventory system based on an automatic ordering principle. However, why does the out-of-stock (OOS) happen in large discount stores in spite of having a good inventory system? This paper suggests two systems after finding the root causes concerning the previous question. For evaluating the performance of each system, the random 200 data set in each sample group was generated from MINITAB 16 and obeyed the Poisson distribution. The existing inventory system in retail market cannot help generating OOS due to indwelling contradiction in itself. The reasons are the ordering deadline and the relationship between ordering quantity and base stock. This paper also demonstrates that these previous studies on inventory fall into the closed loop. Also the paper shows that the performance of the replenishment policy was better than traditional methods dealing with ordering quantity and base stock.

  • This paper selects 100 IT companies listed on the Shenzhen Stock Exchange from 2016 to 2020, and the public announcement in Hwajung collects ESG integrated ratings and grades for each sector and empirically verifies the relationship between ESG ratings and stock returns. Huazheng ESG level data and QIANZHAN database Using corporate financial data, a total of 500 samples were selected through correlation analysis and linear regression analysis with SPSS23 to analyze the effect of ESG on Return. As a result of the analysis, first, the impact on stock returns was found to be a significant positive (+) value for ESG integrated ratings and ratings by E (environment), S (social), and G (governance) sectors, confirming that ESG ratings have a positive mold of corporate stock returns. Currently, the world's major economies have proposed sustainable development strategies and "carbon neutral" goals. Development strategies are very consistent with ESG concepts, and companies that agree and execute ESG concepts may have higher ratings than other companies in the same industry, resulting in certain evaluation premiums. In addition, capital market performance in recent years shows that companies with ESG concepts or "carbon neutrality" concepts are generally considered to have higher growth potential and stronger anti-risk capabilities in the market. For listed companies, they should focus on ESG investment, improve ESG performance, and actively disclose related information to investors. Improving ESG performance should deliver positive information to society, enhance corporate image, increase market confidence in the future development of listed companies, and positively improve corporate value to actively increase financial, financial, trading, and other aspects of negotiation.
