This article explores the factors that influence consumer behavior under the conditions of technological changes and the accompanying social and economic externalities. The research goals were to develop a theory of consumer behavior and, based on such a theory, to consider a conceptual model of a digital consumer behavior during digital transformation. The authors systematized the theoretical approaches to understanding the models of consumer behavior and proposed to supplement the existing groups of models with incremental factors, which are caused by the impact of digitalization on society. Within this approach, network interaction algorithms can accurately predict the needs of each individual and suggest the most optimal way of meeting them. The authors developed a conceptual model of consumer behavior. In this model, on the one hand, the digital consumers are at the center of their own digital ecosystems tailored to their specific needs. On the other hand, using certain elements of the digital environment, they create digital footprints that are useful for other participants in the socioeconomic system. Considering this phenomenon allowed the authors to formulate and describe the social and economic externalities generated by the digitalization of consumption and include these in the proposed conceptual model of consumer behavior. Moreover, the authors studied the relationship between the use of digital technology and the socioeconomic development of countries. These countries were divided into clusters with different relationships between particular social parameters and varying levels of digital consumption. Having examined the dynamics of consumer price indices for certain groups of goods in the Russian Federation, the authors propose the hypothesis about the specifics of the digital consumption culture, which reduce both the transactional and direct costs for the consumer.

Spectral and Hydrodynamic Studies of Complex Formation of Tetraalkoxy Substituted Zinc(II)phthalocyanines with Defatted and Nondefatted Bovine Serum Albumin

Spectral, hydrodynamic and thermochemical studies have been demonstrated that tetraalkoxy substituted zinc(II)phthalocyanines form stable complexes with defatted and nondefatted bovine serum albumin. The phthalocyanines interact with BSA through heteroatoms of their peripheral substitutes. It was found that ZnPc(4-NH-CO-C6H4-OC3H7)4 is located in the protein subdomains IB and IIA whereas ZnPc(4-NHCO- C6H4-OC6H13)4 and ZnPc(4-NH-CO-C6H4-OC8H17)4 are immobilized on surface of the protein globule at a distance of not greater than 10 nm from the tryptophan residues in the positions 135 and 214 of the protein polypeptide chain. Zinc(II)phthalocyanines (ZnPc(4- NH-CO-C6H4-OC6H13)4 and ZnPc(4-NH-CO-C6H4- OC8H17)4) increase thermal stability of BSA.

Background: Prader-Willi syndrome (PWS) is a rare genetic disorder in which seven genes (or some subset thereof) on paternal chromosome 15 (q 11-13) are deleted or unexpressed (chromosome 15q partial deletion). The incidence of PWS is between 1 in 25,000 and 1 in 10,000 live births. There are many signs and symptoms of PWS. The variety of symptoms can range from poor muscle tone during infancy to behavioral problems in early childhood. Clinical case: A 16-year patient presented with complaints on delayed sexual development. Also he had nonspecific symptoms as like increased appetite, rapid fatigability, headaches, dizziness, syncopes, and increased irritability. Past history did not include any information about delayed sexual development. Also medical history demonstrated muscle weakness, decreased sucking refi ex and weight loss before 2 years age. Thereafter, all symptoms disappeared, and reverse symptoms as like polyphagia and increased appetite developed. During the whole period of a disease patient were examined by various specialists, but nobody observed signs and symptoms of delayed sexual development. Physical examination revealed adult woman pattern of hair distribution, testicular hypoplasia and obesity (BMI 42,5 kg/m2). Also patient had acromicria and mental defi ciency. Further, laboratory examination revealed decreased testosterone, LH and FSH. Thus, secondary hypogonadism was diagnosed. Also psychiatrist proved decreased IQ level. Based on all clinical signs and symptoms there were supposed that secondary hypogonadism is a part of some genetic disorder. Further, geneticist established karyotype 46 ХУ with 15q-11-13. As result PWS was diagnosed. Symptomatic treatment, like chorionic gonadotropin, dietotherapy, physical activity and home schooling wasprescribed. Conclusions: This clinical case demonstrates that there is no systematic diagnostics of rare genetic disorders. PWS is multidisciplinary problem that is needed special attention of various specialists. Any symptom as like secondary hypogonadism could be PWS clinical presentations

Case marking strategies in spatial relations Uralic vs. Tungus-Manchu languages

Natalya Koshkaryova,Anna Gerasimova 한국알타이학회 2005 알타이학보 Vol.0 No.15

The Uralic and Tungus-Manchu languages differentiate the concepts of motion and location in their case encoding strategies. The Dative case is associated with motion in Uralic and, conversely, with location in TungusManchu. In both language families the recipient in give-sentences is encoded with the Dative case. Consequently, the Dative case sets the situation of giving into two different perspectives: motion in Uralic, and location (or possession) in Tungus-Manchu. In the Tungus-Manchu languages, the parameter of the motion boundary is relevant for case marking, whereas this parameter remains implicit or underspecified in Uralic. In both Uralic and Tungus-Manchu, the concepts of motion and transfer can be extended to different metaphorical domains. In Uralic the possibilities of such extension are very wide and include emotional, mental and social domains. Even an “action in favor of the beneficiary” is grammaticized as a class of spatial clauses. The Tungus-Manchu languages employ special cases for motion and transfer in mental domain and a special destinative construction instead.

Morphological Characteristics of Residual Skin Surface Components Collected from the Surface of Facial Skin in Women of Different Age

( Natalya E. Chalyk ),( Tatiana Y. Bandaletova ),( Nigel H. Kyle ),( Ivan M. Petyaev ) 대한피부과학회 2017 Annals of Dermatology Vol.29 No.4

Background: Problems of skin aging and its prevention cur-rently attract increasing attention with the growth of human life expectancy. The morphology of the stratum corneum (SC) is well known, but investigation of age-related changes of its structure is difficult in the absence of non-invasive sam-pling methods. The residual skin surface components (RSSC) that overlay the SC can be easily collected non-invasively. Objective: The aim of this study was to examine morphology of RSSC samples collected from the surface of facial skin of healthy female volunteers of different age. Methods: RSSC samples were non-invasively collected from 53 adult female volunteers (22 aged in the range 18∼25 years and 31 aged in the range 50∼73 years). The samples were analysed microscopically. Results: Distinct age-related changes were determined for lipid droplet size, corneocyte desquamation level and lipid crystal count. There was a significant (p=0.0006) decrease in lipid droplet size among older women. Similarly, significantly (p=0.0401) lower lipid crys-tal numbers were present in the older group. Conversely, cor-neocyte desquamation was significantly higher (p=0.0007) in older women. No age-related difference in microbial pres-ence in the RSSC could be detected. Result patterns were generally similar to those previously found in male volun-teers; however gender-related differences in the absolute val-ues were revealed. Conclusion: Non-invasively collected RSSC samples allow identifying age-related changes on fa-cial skin surface. The results of this study highlight gender-de-pendence of distinct elements of age-associated impairment of epidermal barrier and can be employed for developing new approaches to prevent changes associated with skin aging.

Social Change and Marriage Patterns among Koryo Saram in Kazakhstan, 1937–1965

( Natalya Yem ),( Stephen J Epstein ) 서울대학교 규장각한국학연구원 2015 Seoul journal of Korean studies Vol.28 No.2

This article considers social forces set in motion when ethnic Koreans of the former Soviet Union (Koryo saram) were deported from the Soviet Far East to Central Asia under Stalin, treating these emerging phenomena as a context for understanding the community’s marriage patterns. Drawing on archival records from 1937 to 1965 in Kazakhstan, we show how choice of marriage partner reflects changes in socioeconomic status, places of residence, gender roles and language use. Demographic data about interethnic marriages in Kazakhstan, we argue, serves as a useful tool for exploring relations between Koryo saram and the larger host society; these evolving trends in marriage patterns offer a window into the Korean diaspora experience locally and more broadly.

( Natalya Iorio ),( Kian Makipour ),( Amiya Palit ),( Frank K Friedenberg ) 대한소화기기능성질환·운동학회 2014 Journal of Neurogastroenterology and Motility (JNM Vol.20 No.4

Background/Aims Psychosocial stressors likely play an important role in irritable bowel syndrome (IBS). The association between IBS and post-traumatic stress disorder (PTSD) in non-minorities has been described. Our aim was to investigate the potential association between IBS and PTSD in an urban African American population. Methods Our institution maintains a longitudinal population-based survey of African Americans (AA). The survey utilizes a complex, stratified sampling design. The study group consisted of adult AA meeting Rome III criteria for IBS of any subtype. The 4-item Primary Care PTSD screener was administered; score of ≥ 3 (range, 0-4) was considered positive for PTSD. Depression (Public Health Questionnaire-9 depression) and anxiety (generalized anxiety disorder-7) levels were measured using standardized scales. To assess quality of life, norm-based physical and mental component summary scores from the short-form 36 health survey version 2 were obtained. Descriptive and inferential statistics were calculated using Complex Sample Module of SPSS after weighting of the study sample. Results Four hundred nineteen subjects included corresponded to a weighted 21,264 (95% CI, 19,777-22,751) individuals. The prevalence of IBS in our sample of urban AA was 8.2%. In multivariate regression analysis, female gender, age > 40, higher educational attainment and divorce were independently associated with IBS. Those with IBS were considerably more likely to suffer from PTSD (OR, 4.54; 95% CI, 4.07-5.06). PTSD was independently associated with depression, anxiety, harmful drinking and substance abuse. Conclusions In AA, PTSD is independently associated with IBS. PTSD has a significantly negative impact on physical and mental self-assessment of quality of life. Evaluation of minorities presenting with functional gastrointestinal disorders should include screening for PTSD.

SHARE REPURCHASES IN KOREA: WHY DO COMPANIES CARRY THEM OUT?

Natalya Li,Jongcook Byun,Jeong Yun Park 한국로고스경영학회 2006 한국로고스경영학회 학술발표대회논문집 Vol.- No.-

This paper examines stock price behavior surrounding announcements of stock repurchases made by Korean firms from August 1999 to December 2004. The results of event study show that like in the US market stock prices followed by the stock repurchases in Korea are increased in response to stock repurchase announcements. Dividing the whole sample according to the size of the companies, this study found that the stock price returns in the small size firms were higher than those in the large firms. Thus, this result supports the “small firm effect” hypothesis. Previous studies on share repurchases state that Korean companies use share repurchases to signal undervaluation in their firms. However, we could not find to support this hypothesis. Recent changes in the market situation may cause changes in the fit of the previous hypotheses to the modern market conditions. Regression analysis results show that free cash flow may be the reason why companies in Korea announce share repurchases at present.
