  • The silkworm Bombyx mori L. was studied as the potential “host” of popular in Uzbekistan biocontrol ectoparasite, entomophagous Bracon hebetor Say. Being one of representatives of economic-beneficial insects, the silkworm (larvae, pupae and imago) can be used as highly sensitive test organism for revealing of neuro toxic effects of insects venom as well as of their purified components in screening assays. In comparative aspect, except a mulberry silkworm, representatives of Uzbekistan pests cotton-boll worm Helycoverpa armigera Hbn., lesser mulberry pyralid Glyphodes pyloalis Wlk., codling moth Corpocapsa pomonella L., malaria mosquito Anopheles claviger and Colorado potato beetle Leptinotarsa decemlineata Say have been subjected to insect toxic test of bracon venom gland extract (VGE) and its fractions which were obtained by gel-chromatography on Sephadex G-100. The paralyzing effect of the VGE and its fractions was shown in a various degree on the pests.

  • This paper uses a probability-based approach to study the spatial relationships between landslides and their causative factors in the Mingchukur area, Bostanlik districts of Tashkent, Uzbekistan. The approach is based on digital databases and incorporates methods including probability analysis, spatial pattern analysis, and interactive mapping. First, an object-oriented conceptual model for describing landslide events is proposed, and a combined database of landslides and environmental factors is constructed by integrating various databases within a unifying conceptual framework. The frequency ratio probability model and landslide occurrence data are linked for interactive, spatial evaluation of the relationships between landslides and their causative factors. In total, 15 factors were analyzed, divided into topography, hydrology, and geology categories. All analyzed factors were also divided into numerical and categorical types. Numerical factors are continuous and were evaluated according to their $R^2$ values. A landslide susceptibility map was constructed based on conditioning factors and landslide occurrence data using the frequency ratio model. Finally, the map was validated and the accuracy showed the satisfactory value of 83.3%.

  • This paper focuses on the emerging patterns of educational mobility and unskilled labor migration from Uzbekistan to Japan and South Korea. Labor migration and educational mobility are becoming the next "horizon" in the expanded relationship between East and Central Asia, powered by several factors, including the efforts by Japan and South Korea to build "original" people-oriented policy engagements with the region and the demand from Central Asian states, such as Uzbekistan, to provide more labor opportunities to their young and growing populations. This paper presents the initial findings of a pilot survey that explores and occasionally compares the experiences of Uzbek migrants to Japan and South Korea, using datasets of face-to-face interviews related to various aspects of life in Japan and South Korea. The interviews were conducted face to face and online (Telegram, Skype, etc.) with 66 migrants and Japanese language school students (whom this paper treats as labor migrants masquerading as students) in Japan from November 2019 to January 2020 as well as online with 30 laborers and students in South Korea from August to September 2020.

  • Cystic echinococcosis (CE) is one of the most widespread zoonotic helminthiases, which can last an asymptomatic infection for several years. The purpose of this study was to demonstrate serum antibody prevalence of CE among asymptomatic people in Uzbekistan using ELISA. A total of 2,547 serum samples were collected, 66 from confirmed CE patients and 2,481 of patients with other diseases than CE at a hospital in Tashkent, Uzbekistan. The serum samples were screened for CE specific IgG antibodies by ELISA using cystic fluid antigen obtained from sheep. The serum antibody positive rate was 89.4% (59/66) in CE and 3.6% (89/2,481) in other disease patients. The present ELISA recognized 89.4% sensitivity and 96.4% specificity. The ELISA absorbance of positive samples was distributed 0.271-0.971 for CE and 0.273-0.887 for other disease patients. The other disease patients with high absorbance over 0.3 were 50 (2.0%) who were presumed to be active CE patients. The patients in their 40s showed the highest positive rate of 5.2% (P=0.181), and women were 4.4% while men were 3.1% positive (P=0.136). The data confirmed that there are many asymptomatic patients of CE in Tashkent. It is indicated that CE is an endemic disease of public health importance in Uzbekistan.

  • The purpose of this study was to identify the impact of generation on the traditional food culture of Uzbekistan-Koreans. The generation of Uzbekistan-Koreans was divided into two groups i.e., the second and third generation. The second generation suffered from the compulsory emigration during 1930s because of the minority racial breakup policy by the Soviet Russia. The third generation was born after the compulsory emigration and the economic condition was much better for them. In terms of identifying traditional food culture, generation was an important factor because each generation had different social environments and different life styles. Data were collected from 634 Koreans living in Uzbekistan and analyzed by chi-square and correlation analysis. The results of this study revealed that the impact of generation was an important factor regarding the traditional food culture. Chi-square analysis showed that factors related to making a menu, food priority, and consideration of the person preparing the food were likely to vary depending on the generation. Also, reasons for preferring traditional food and preparing foods for family events as well as national holidays were different between the second and the third generation. The second generation preferred traditional food because of flavor, while the third generation preferred traditional food because of nutrition. For family events and national holidays such as New Year's Day, the second generation was more likely to prepare traditional foods than the third generation. The correlation analysis indicated that the relationship between preference and intake frequency of traditional foods was positively related, and the degree of correlation was higher for the second than the third generation. Similarities and differences between generations were discussed, and implications for food and nutrition specialists and food marketers were provided.

  • The purpose of this study was to analyze the state of Goryoin housing in Uzbekistan and Korea. Using ethnographic methodologies, it was examined that 20 Goryoin households in Korea in relation to their usage of housing space firstly and also tried 20 Goryoin households in Uzbekistan with the same method. The following conclusion were established; 1). The majority of households in both areas preferred separated kitchen and living room areas. 2). Most households in both areas had a washing machine in bathroom and they regarded bathtub and the drain hole of the bathroom as very necessary. They all preferred separate bathroom and toilet areas in order to allow simultaneous use. 3). Their preferred seating style was chairs on sleeping and eating especially but they treated large family and guest without chairs in both areas. 4). All of them were took their shoes off and wore slippers at home usually and also had a preference for designated shoes space at the entrance to the house. 5) All of households in Uzbekistan and half of them in Korea had a carpet or mat in the bedroom or living room, both for keeping warm and aesthetic reasons. 6). The heating system of apartment in Uzbekistan was radiator and most of private houses had a modified Ondol with radiator but their preferred heating system was modified Ondol in both areas. 7). They all considered the living room as the most important housing space for family and guest in both areas.

  • This study aimed to determine the prevalence of intestinal helminth parasitic infections and associated risk factors for the human infection among the people of Samarkand, Uzbekistan. Infection status of helminths including Echinococcus granulosus was surveyed in domestic and wild animals from 4 sites in the Samarkand region, Uzbekistan during 2015-2018. Fecal samples of each animal were examined with the formalin-ether sedimentation technique and the recovery of intestinal helminths was performed with naked eyes and a stereomicroscope in total 1,761 animals (1,755 dogs, 1 golden jackal, and 5 Corsac foxes). Total 658 adult worms of E. granulosus were detected in 28 (1.6%) dogs and 1 (100%) golden jackal. More than 6 species of helminths, i.e., Taenia hydatigena, Dipylidium caninum, Diplopylidium nolleri, Mesocestoides lineatus, Toxocara canis, and Trichuris vulpis, were found from 18 (1.0%) dogs. Six (T. hydatigena, Toxascaris leonina, Alaria alata, Uncinaria stenocephala, D. caninum, and M. lineatus) and 2 (D. nolleri and M. lineatus) species of helminths were also detected from 5 Corsac foxes and 1 golden jackal, respectively. Taeniid eggs were found in 2 (20%) out of 10 soil samples. In the present study, it was confirmed that the prevalences of helminths including E. granulosus are not so high in domestic and wild animals. Nevertheless, the awareness on the zoonotic helminth infections should be continuously maintained in Uzbekistan for the prevention of human infection.

  • While in high-income countries the development of digital technology began in the 1970s, in low- and middle-income countries it began in the 1990s and even after 2005, due to the political regime that constrained economic development and innovation. At the same time, there are no studies of the relationship between technological development and structural changes through innovation in low- and middle-income countries. The article aims to quantify the relationship of the introduction of digital technologies on innovation, structural transformation of low- and middle-income economies. The industrial-agrarian economy of Uzbekistan with an authoritarian regime is in a state of transition to a market economy, while in Ukraine, there are active processes of Europeanization and integration into the EU. Ukraine's economy is commodity-based (the export of raw materials of industries and the agricultural sector in developed countries predominates) and industrial-agrarian. Digital technologies and the service sector are little developed in Uzbekistan. On the other hand, Ukraine has a more developed ICT sector. Uzbekistan is gradually undergoing an innovative and structural transformation of the economy: the productivity of the agricultural, industrial, and service sectors is growing, but the ICT sector is virtually undeveloped. In comparison, in Ukraine, there are no significant structural transformations due to a significant drop in productivity of the industrial sector, with stable growth of productivity of the agricultural sector due to technology and a slight increase in productivity of the service sector. It is revealed that Ukraine and Uzbekistan have undergone structural transformations of the economy in favor of the service sector, while the agricultural and industrial sectors produce less and less. If Uzbekistan remains the industrial-agrarian country with an aggregate share of the added value of these sectors 59% in 2019, Ukraine transits to the post-industrial type of economy where the added value of the service sector in GDP grows (55% compared to agrarian and industrial sectors at 42%).

  • The mobile telecommunication sector is increasingly gathering way becoming a key area for the economic development in Uzbekistan. One way to promote competition among providers is the introduction of a number portability service. This paper estimates subscriber's willingness to pay (WTP) for the MNP service in the mobile communication market in Uzbekistan. Consumer valuation was estimated using a conjoint analysis. Since number portability had not been introduced at the time of the study, stated preference data from the conjoint survey was used. Results indicate that currently subscribers do not attach a lot of importance to the MNP service, while price and service quality are most valuable components. The results of this study provide important implication for mobile network operators and policy developers on potential MNP implementation.
