Bright rays are often observed after coronal mass ejections (CMEs) erupt. These rays are dynamical structures along which plasmas move outward. We investigated the outflows along the post-CME rays observed by the COR2 on board STEREO Behind on 2013 September 21 and 22. We tracked two CMEs, two ray tips, and seven blobs using the NAVE optical flow technique. As a result, we found that the departure times of blobs and ray tips from the optimally chosen starting height of 0.5 $R{\odot}$ coincided with the occurrence times of the corresponding recurrent small flares within 10 minutes. These small flares took place many hours after the major flares. This result supports a magnetic reconnection origin of the outward flows along the post-CME ray and the importance of magnetic islands for understanding the process of magnetic reconnection. The total energy of magnetic reconnection maintaining the outflows for 40 hr is estimated at 1.4' 1030 erg. Further investigations of plasma outflows along post-CME rays will shed much light on the physical properties of magnetic reconnection occurring in the solar corona.

Four stream- activated carbons were prepared by carbonizing apricot stones at $600^{\circ}C$ followed by gasification with steam at $950^{\circ}C$ to burn-off's=17, 32, 49 and 65%. The textural parameters of these activated carbons were determined from nitrogen adsorption results at 77 K. The total pore volume and the mean pore radius increased with the increase of % burn-off whereas the surface area increased with the increase of burn- off from 17 to 32 and further to 49%. Further increase of burn-off to 65% was associated with a considerable decrease in surface area as a result of pronounced pore widening due to pore erosion. The surface pH values of the carbons investigated range between 7.1 and 8.2. The adsorption of oxamyl onto the activated carbon followed pseudo-second order kinetics and the equilibrium adsorption isotherms fitted Langmuir adsorption model. The adsorption of oxamyl proved to be of the physical type and took place in non-micropores. The amount of oxamyl adsorbed expressed as $q_m$ depends to a large extent to the surface area located in non-micropores $S^{\propto}\;_n$, where a straight line relationship passing through the origin was obtained.

Recently, people's attitude toward residential environment has been changed from a simple shelter to a place affecting their mental function, and the change has increased demand for high quality of residential environment. Nevertheless, a number of unsatisfactory elements that do not meet the demand of residents for residential environment have continuously caused them to be exposed to stress. The purpose of this study is to explore the importance of residential environment by examining stress factors from the residential environment and finding out the effects of the residential environment stress on human emotional intelligence quotient and its application pattern. This study was carried out using not only self-report questionnaires with the Likert 5-point scale to find out the origin of residential environment stress factors, but the emotional intelligence quotient measuring device developed by Wong & Low (2000) to analyse correlations between the residential environment stress and emotional intelligence quotient. The questionnaire survey in this study was carried our among students of D College, and data were analysed using the statistical program SPSS, version 14.0.

Nowadays kimchi is exported to 80 countries and can be easily found overseas, but the name "Korean Kimchi" has not been protected internationally. Korean kimchi need to be registered as a geographical indication and receive international protection in order to establish its status as the country of origin. With the revision of the Kimchi Industry Promotion Act in 2020, geographical indications were introduced for kimchi and a legal basis was in place to enable the geographical indication as "Korean Kimchi" or "Republic of Korea Kimchi." Although there are issues remaining between the current system and producers' associations, we should prioritize the geographical indication as a means of protecting the country's agricultural products. In addition, efforts should be made to improve the quality and product value of Korean kimchi so that it is also recognized as a global brand.

This paper investigated the purchase behavior of Kimchi products by surveying housewives in Jeonbuk area who have purchased Kimchi products. The studied consumers purchased Kimchi products for the convenience and time-saving aspects. Factors taken into account when purchasing Kimchi were hygiene, taste and ingredients. The main places of purchase for Kimchi products were large discount markets. The purchase information paths were product displays at stores and recommendations from acquaintances. The most purchased type of Kimchi products was cabbage Kimchi. An one-time purchase amount was 10,000~30,000 won. The most purchased size was to be 500 g~1 kg. Desired improvements for Kimchi products were a display of the ingredients origin, exclusion of monosodium glutamate, freshness, and hygiene. Based on the results, this research aids in analyzing the marketing mix (4P: product, price, place, promotion) of Kimchi products for Kimchi manufacturers.

We consider a ruin model where the surplus process is formed by a Brownian motion. If the level of surplus exceeds V, then we assume that a insurer invests an amount of S to other place. In this paper, we apply martingale methods to the surplus process and obtain the expectation of period T, time from origin to the point where the level of surplus reaches either V or 0. As a consequence, we finally derive the total and average amount of surplus during T.

Purpose: Sports is an activity created by human beings and is related with natural and human environments, and it is a physical activity which inherently interacts with geographical properties. With the above views, it is clear that sports reflect human culture and physical environment, which are closely related to places or spaces in terms of origin, propagation and diffusion, or geography in a broader sense. This study explored the relationships between sporting activities and geography with an environmental view. Research design, data, and methodology: The study employed qualitative methodology to review the association between sport and geographical perspective. The study reviewed the broad documents including journals, periodicals, reports and so forth. Results: First, since its inception in the 1960s, research on sports geography has been steadily studied in many international geography and non-geographic research journals. Second, it reflects the distinct characteristics of the relationship between sports and geography (relationship with physical geography and humanities). Third, as a spatial approach to sports, it is the place of sports, globalization of sports, and the tourist attraction of sports. Conclusion: the findings of this study provides insights for sport geography and could be applied to the current sports industry. Further implications were discussed.

The purpose of this study was to investigate Chinese women’s clothing purchase behavior and satisfaction for clothing made in Korea. Data was collected from Chinese women who had made purchases of Koreanmanufactured clothing using the Chinese online shopping mall named ‘TaoBao’. In total, the responses of 439 questionnaires were tabulated and analyzed using the SPSS program 12.0. Results were as follows: 1) Shopping motivation was classified based on two factors: transformation motivation and information motivation. Most Chinese women who purchased clothing made in Korea did so because of information motivation. Results showed that the place of manufacturing origin(i..e Korea) did not negatively impact Korean clothing products at this online shopping mall. 2) Purchase satisfaction was influenced by three factors: quality satisfaction, wearing/management satisfaction, and design satisfaction. Most Chinese women were satisfied with clothing made in Korea in terms of the design factor. 3) There were correlations among Chinese women’s shopping motivation and purchase satisfaction for clothing made in Korea.

We investigate the impacts of tariff, tariff-rate quota, conformity assessment, and traceability requirements set by the rice importers using panel data of 17 rice exporters exporting to 119 countries in two years 2015 and 2018, using both Ordinary least square (OLS) and Poisson pseudo maximum likelihood (PPLM) methods. Results from our gravity models strongly indicate that tariff and tariff rate quota remain significantly detrimental to the world's rice exporters because these measures place downward pressure on the rice exporters' prices and the importers' import quantity, creating barriers to market participation. Our study also provides strong evidence about the role of origin certificates in allowing rice exporters to gain access to foreign markets. Meanwhile, regulatory standards such as traceability requirements and logistical and distributional requirements imposed by the rice importers are found to be major obstacles to rice importation from less-developed countries. Our study provides insights into tariff and non-tariff barriers existing in the global rice market, which is likely to assist policymakers operating in developing countries to help shape their policies and bolster rice competitiveness.
