In the semistructured distributed documents, it is very difficult to formalize and implement the query processing system due to the lack of structure and rule of the data. In order to precisely retrieve and process the heterogeneous semistructured documents, it is required to handle multiple mappings such as 1:1, 1:W and W:1 on an element simultaneously and to generate the schema from the distributed documents. In this paper, we have proposed an query processing algorithm for querying and answering on the heterogeneous semistructured data or documents over distributed systems and implemented with a metadata interface. The algorithm for generating local queries from the global query consists of mapping between g1oba1 and local nodes, data transformation according to the mapping types, path substitution, and resolving the heterogeneity among nodes on a global input query with metadata information. The mapping, transformation, and path substitution algorithms between the global schema and the local schemas have been implemented the metadata interface called DBXMI (for Distributed Documents XML Metadata Interface). The nodes with the same node name and different mapping or meanings is resolved by automatically extracting node identification information from the local schema automatically. The system uses Quilt as its XML query language. An experiment testing is reported over 3 different OEM model semistructured restaurant documents. The prototype system is developed under Windows system with Java and JavaCC compiler.

This study was conducted to determine the intake and satisfaction levels of Busan local foods in Japanese tourists visiting Busan. The degree of satisfaction with Busan foods and services in restaurants was evaluated. What these tourists wanted to eat after touring Busan was also determined. The subjects consisted of 100 Japanese tourists visiting Busan. Women (including housewives), highly educated people, and people who visited more than four times were predominant in number among the Japanese tourists. Busan local foods eaten during touring were: Dongrae Pajeon (29%), Sengsunhoe (21%), Daejikukbap (10%) and Haemultang (10%). Tourists wanted to taste local foods and answered that eating local foods during the tour was important. A variety of menu items earned a high score of 3.8 (from a highest possible score of 5.0) and various dessert items received a low score of 2.7 for satisfaction with Busan foods. In general, the satisfaction level for Busan foods was low. Tourists responded that they wanted to eat Bulgogi, Pajeon, Bibimbap, Sengsunhoe, and Kimchi jjigae in that order if they revisit Busan, indicating their preference for general Korean foods rather than Busan local foods. From all of the activities included in touring Busan, foods received the highest points (51%) in terms of attraction. As fifty four percent of subjects answered that they wanted to revisit Busan. Busan city needs to prepare tourist restaurants for Bulgogi, Bibimbap, Pajeon, and seafoods (including Sengsunhoe). They must also improve Busan local foods and restaurant services in order to attract and satisfy the Japanese tourists industry.

The fast expansion of super supermarket(SSM) in Korean retail industries has attracted serious social attentions and some types of regulations to slow down its growth are prepared. However, the regulations are hardly justified because they attempt to establish entry barriers which are not recommendable economic policy. Accordingly, the regulations should be justified at least on the basis of social and political causes. The study interprets the social and political causes as the effects of entry of SSM on trading ares where SSM is located. The study is distinguished from the past studies which focused only on intertype and intratype competition between retailers Another goal of the study is to complement the weakness of past studies and provide additional information to settle the issues. More closely, the study investigates the relationships between the changes in sales of convenience stores, which may be a surrogate measure of the viability of a local economy, and the changes in the composition of business types within 500m radius of a SSM. Further, the study investigates the effects of the establishment of SSM and the retail sales index on the sales of convenience stores. The study analyzed the panel data and adopts Swamy's random coefficient models. The results show that the effects of the establishment of SSM on the sales of convenience stores are not statistically significant. The relationship between the change in the portion of restaurants among the local business and the change in the sales of convenience stores is positive. On the other hand the relationship between the change in the portion of retailers in the composition of local businesses and the change in the sales of convenience stores is negative. In conclusion, even though any negative effects of the establishments of SSM on local economies are expected, as long as other types business especially restaurant businesses fill the space left by retailers, the net effect on the local economy may not be signification or even positive.

The purpose of this study was to investigate that to see how their traditional characteristics were reflected and expressed in Hanoi vietnamese contemporary public restaurants. For this, We visited Hanoi twice to have onsite research in August 2012 and 2013. According to the results of surveying Vietnamese public restaurants, all of the 12 cases had humane characteristics reflecting Vietnam traditional culture, showing Vietnamese unique traditional characteristics including intangible elements such as natural environment, life culture elements such as food culture, and formative aesthetic elements using indigenous ornaments. Different from luxury restaurants that had trade names on the theme of historical stories related to people or places and expressed various concepts formatively using photographs of Vietnamese politics and history and ornamental elements such as tableware, however, the public restaurants were simple in theme or concept. It is probably because most of the surveyed cases were situated in the old quarter to the north of the Hoan Kiem Lake and in the area to the west of the lake and their target customers were local people, so they reflected the Vietnamese traditional residence style and common people's life rather than designing the restaurants intentionally with specific concepts. As to the spatial expression characteristics of the surveyed cases, casual restaurants in Hanoi expressed only basic structure using basic construction materials and techniques with outdoor spaces in the form of Vietnam traditional tube house, and therefore, the overall atmosphere was contemporary. In indoor spaces as well, the general level was low, using uncharacteristic common design and color and cheap finishing materials and furniture. 83% of all cases showed the pattern of VM-VM-VT, being mainly contemporary by partially adopting Vietnamese unique ornamental elements for their outdoor and indoor spaces and using traditional elements supplementarily.

The main purpose of this paper is to analysis the growth process of new emerging Korean society in Georgia, the USA by investigating changes in the regional distribution of Korean business located in metro Atlanta region. More specifically, it aims to identify the characteristics of spatial distribution of Korean business in metro Atalanta through their locational trends since 1980s. To this end, it has explored the history of Korean migration into Georgia and the locational trends of Korean firms in metro Atlanta by industries. As a result, the main location of Korean firms has expanded into the northeastern regions of Atlanta due to the development of transportation, new regional development, education environment and changes in residential distribution by ethnic. Also, the main Korean business has transformed from retails and restaurant to real estate and finance because of changes in market strategies, institutions and Korean local migration.

This study was executed to evaluate the immune activity, nitrite scavenging activity and ABTS radical scavenging activity against extracts of various concentration of ethanol solvent from Codonopsis lanceolata cultured at 6 local regions. The immune responses from both human T and B cell line was significantly enhanced in the cell growth compared to control while the cell growth was influenced at a certain period of culture. The results revealed that the cell growth of both human T and B cell was altered in a time dependent manner. The nitrite scavenging activity of ethanol extracts from various solvent concentration of C. lanceolata were affected by pH. At a pH of 1.2, the nitrite scavenging effect of all of the extracts tested observed higher than that of the other two pH ranges. There was no distinct detection of nitrite scavenging effects of the pH range 6.0. The ABTS radical scavenging activity was progressively increased in a dose-dependent manner, and the activity was the highest in 100% ethanol extract. The result from this investigation suggests that the extract of Codonopsis lanceolata could be an addition to basic medicine for immune modulation and natural food additives.

Many people reported suspected food poisoning after consuming food at the same snack bar on June 18, 2020. Thus, an in-depth epidemiological investigation was conducted to identify the infectious agent and establish additional food poisoning prevention measures. The study included people who reported to the local public health center after June 18 with acute gastroenteritis symptoms within 4 days of consuming food from the snack bar. The onset of symptoms and food items consumed by individuals were then investigated via phone calls and on-site visits. Afterward, the infectious agent was identified from human samples (stool or rectal swab) of four restaurant employees and 89 people and from environmental samples (materials, cooking utensils, and water). The analysis revealed that the incubation period ranged from 2 hours to 92 hours, with a median and mode of 16 hours and 12 hours, respectively. Moreover, the epidemic curve had a unimodal shape because of common exposure, which reached its peak on June 18. After monitoring for 8 days, which is more than twice the maximum incubation period of 92 hours, the end of the epidemic was declared on June 28 as no additional cases were reported. Analysis of human and environmental samples revealed Salmonella bareilly of the pulsed-field gel electrophoresis pulsotype SAPX01.017 as the causative agent. Therefore, it was concluded that the food poisoning outbreak was caused by S. bareilly.

In this study, the preference for Korean Kimchi by Chinese people in Shandong Province was evaluated. Specifically, this study was conducted to aid in the introduction of Kimchi to China by providing information and developing local types designed to meet regional taste preferences. The subjects were comprised of 298 Chinese (male 108, female 190) residents of Weihai, Yantai and Qingdao, in Shandong province, China. The subjects were provided with a self administered questionnaire form designed to evaluate their views on Korean Kimchi. The collected data were then analyzed using the SAS software package. The results revealed that 95.3% of the respondents were aware of Korean Kimchi. In addition, 100% of the respondents who had visited Korea and 98.1% of the respondents who had an interest in Korea were aware of Kimchi. With regard to the origins of their interest in Kimchi, 26.8% of the subjects answered 'through mass media', while 23.9% reported that they learned about Kimchi 'through friends'. Most subjects recognized Kimchi as a 'Korean traditional food' (92.6%), a 'delicious food' (53.2%), and a 'fermented food' (38.0%). Baechu Kimchi was found to be the most well-known Kimchi, followed by Kkakdugi, Oi Kimchi, Yoelmu Kimchi and Nabak Kimchi. Additionally, 69.1% of the subjects knew how it was prepared, most of whom reported that they learned how Kimchi was prepared through 'Korean movie and/or drama'. Moreover, 88.9% of the subjects had eaten Kimchi. Overall, 43.8% of the subjects reported that they ate Kimchi $1{\sim}2$ times per month, while 32.1% reported that they ate Kimchi $1{\sim}2$ time per year. The most common places that Kimchi was eaten were a 'Korean restaurant' (67.6%) or with a 'colleague' (32.8%). The primary reasons for not having eaten Kimchi were 'no knowledge or dislike of Kimchi by family' (30.3%), 'difficulty purchasing Kimchi' (21.2%), 'high priced Kimchi' (21.2%), and 'dislike the smell and shape of Kimchi' (12.1%).
