A Method for Modeling and Verifying of UML 2.0 Sequence Diagrams using SPIN
Authors: Le Luan Chi
Published: November 2021

Abstract— This paper proposes a method for modeling and verifying UML 2.0 sequence diagrams using SPIN/PROMELA. The key idea of this method is to generate models that specify behaviors of each object in the given UML 2.0 sequence diagrams. In this paper, I/O automata are used as the models to maintain the interaction among objects. This work also proposes a mechanism to translate these models into PROMELA to use SPIN for checking the correctness of the system. By ensuring software design correctness, several properties can be guaranteed such as safety, stability, and the fact that no vulnerability is left. A support tool for this method is presented and tested with some particular systems to show the accuracy and effectiveness of the proposed method. This approach has promising potential to be applied in practice.Tóm tắt— Bài báo này đề xuất một phương pháp để mô hình hóa và kiểm chứng biểu đồ trình tự UML 2.0 sử dụng SPIN/ PROMELA. Ý tưởng chính của phương pháp là xây dựng các mô hình mô tả hành vi của từng đối tượng trong biểu đồ trình tự UML 2.0. Các mô hình này biểu diễn dưới dạng các ôtômát vào/ra nhằm giữ nguyên tính tương tác giữa các đối tượng. Nghiên cứu đưa ra một kỹ thuật hỗ trợ chuyển đổi các mô hình này thành các đặc tả PROMELA để cung cấp cho bộ công cụ SPIN nhằm kiểm chứng tính đúng đắn của các biểu đồ tuần tự. Bằng cách đảm bảo tính chính xác của thiết kế phần mềm, một số thuộc tính có thể được đảm bảo như an toàn, ổn định và thực tế là không còn lỗ hổng nào. Một công cụ hỗ trợ cho phương pháp đề xuất cũng được cài đặt và thực nghiệm với một số hệ thống điển hình nhằm minh chứng cho tính đúng đắn, hiệu quả và dễ sử dụng. Cách tiếp cận này hứa hẹn sẽ được áp dụng trong thực tế.

Absurdes in der Kunst
Authors:   ", Angelov Valentin ,   St. Cyril and Methodius",   University of Veliko Tarnovo
Published: November 2021

Das Absurde in der Kunst ist seit vielen Jahren bekannt, am meisten als Auseinandersetzung mit der alten Moral und Kritik an den negativen Kehrseiten der Gesellschaft. In der modernen Kunst aber erscheint das Kunstabsurde vielmals als Selbstzweck ohne moralische oder soziale Ziele (z. B. bei dem schweizerischen Maler H. R. Giger). So dient es als wichtiges Mittel einer schoepferischen Originalitaet und ueberzeugender Beweis des eigenen Weg in der bildenden Kunst. Der Surrealismus sucht das Absurde als ein Umherirren in den undurchdringlichen Schichten des Unterbewusstseins, als intuitives Beruehren zur Lebenswahrheit. Im Gegenteil sucht der Absurdismus eine oder andere absurde Situation rationell, vernunftmaessig, als eine durchgedenkte oder kritische Beziehung zur realen Welt. Bei uns in Bulgarien gibt es typische Vertreter des Absurdismus in der bildenden Kunst, leider die meisten unter ihnen wenig bekannt fuer die breite Oeffentlichkeit.

KATYA. Theme and Motive for an Exhibition
Authors:   ", Tsvetkova Galina ,   St. Cyril and Methodius",   University of Veliko Tarnovo
Published: November 2021

“Katya” is the title of an exhibition thought and realized in postmodern, with the aspect of recreation of well known styles and themes in art in nowadays context. Planned as a study experiment, but transformed into an author’s project. Throughout the exhibition some will find the signature of works of Picasso, others will recognize Katya – professional model for candidate-artists in the Faculty of Fine Art. The social and educationally effective status of Katya is a challenge to the potential academic system to generate ideas in the routine of the process, which must legitimate knowledge and cultivate affinity towards art. Her image is a direct and spontaneous association with the art conception of the “Blue period” of Picasso, in which the artist shows his empathy to people, made to live in poverty, humiliation and suffering. Hypothetically put, Katya is a prototype of Picasso’s works, but this author’s recourse does not provoke representation, which aims to imitate, but is in deep, fundamental connection, close to identity with the typological profile of the “Blue period.”

Published: November 2021

In order to define a reasonable value of Apple’s stocks, a number of valuation models can be considered, including FCFF model, DDM, VC method, FCFE model and multiples valuation model. In the research, we use WACC and DCF calculation to evaluate the Apple company’s further value, and judging whether it is undervalued or overvalued based on historical data and market direction. As different models and data provide various results, they have different limitations and uses. For DCF, although some of the data used in its calculations are based on people's subjective analysis of the future, its valuation serves as a baseline for the target price, making its results relatively conservative and reasonable. Based on the results generated by valuation models, we think Apple still has a great potential to develop, and we advise customers to buy or hold the stock.

Authors: Li Boda
Published: November 2021

The network retail industry has been in a highly centralized pattern. According to the relevant concepts in the traditional industrial organization theory, this highly concentrated market needs regulation. Behind the rapid development of industry is the hidden worry that is constantly exposed. In 2011, Taobao announced a substantial increase in annual fees and software service fees, which caused conflicts with small and medium sellers. In the price war in Jingdong, it may have been sold at a price lower than the cost. The traditional industrial organization theory usually thinks that the monopoly market structure is not good. Because of its pricing model based on its own marginal cost and marginal income, it will cause welfare losses to consumers, resulting in low market efficiency and unnecessary losses. This paper first expounds the basic connotation and judgment criteria of monopoly, analyzes the monopoly and characteristics of online retail industry in the "Internet +" era, and finally puts forward some governance strategies for the monopoly problems existing in the current online retail industry.

China's Economic Situation, Response and Prospect under the Epidemic Situation
Authors: Guo Lan
Published: November 2021

On the basis of the demand side and the supply side, the paper respectively analyzed how novel Coronavirus affected Chinese economy: the weak demand caused the demand curve to move to the left, equilibrium output decreased and equilibrium price decreased. Due to the reduction of labor costs, enterprises have the incentive to increase production capacity at the production end. However, when the price is lower than the average variable cost of enterprises, the number of bankruptcies in the society starts to increase. One of the immediate causes of the economic downturn caused by COVID-19, which led to GDP growth of -6.8% in the first quarter of 2020, is a lack of consumption. Therefore, it is suggested that the government can appropriately reduce consumption tax and issue consumption vouchers, to improve consumer confidence and increase output. The ARIMA model was used to predict economic growth for the next seven quarters.

Unpacking Leadership Style Values on Motivating New Generation Employees’ Prosocial Organizational Behaviors
Authors: Liu Siyang
Published: November 2021

Based on current data derived from the International Labour Organization, in 2018, there was a significant rise of Chinese female entrepreneurs in workplaces. One industry that has been viewed the most significantly rise in female leadership is Internet industry, as Chinese women now account for 55% of entrepreneurs within new economy companies. Existing researches distinguished leadership styles into two types based on gender differences. More specifically, men are generally viewed to lead with Task-oriented styles while women have been shown to lead with Interpersonal-oriented styles. However, no studies have directly examined which leadership style can be the most effective when directing GenZ employees in China in terms of prosocial organizational behaviors. In this paper, the author profoundly extends the leadership style values and latent women leadership superiority on motivating prosocial organizational behaviors of Genz employees. Extracting from shared points of leadership styles based on gender types, the author generated 3 hypotheses: Compared with Task-orientated leadership style, interpersonal leadership style is more accepted by Genz employees compared to Millennial (Hypothesis1) and Women prosocial leadership are more acceptable by female GenZ employees (Hypothesis2). Notably, GenZ employees’ prosocial organizational behaviors are motivated when collaborated with most felicitous leaders (Hypothesis3). A sample of 500 applicants in a top internet company were expected to accomplish this research. Consequences provided sufficient evidences for hypothesis 2 through both quantitative and qualitative statistics as well as hypothesis 3. Nevertheless, Hypothesis 1 have not been proved in an accurate manner that generational differences in employees have paltry ramifications of leadership styles preferences. As a matter of fact, both leadership styles are popular among Millennial and Genz employees.

Authors: Zhou Panxin
Published: November 2021

Today, Supply Chain Management (SCM) is regarded as an essential strategic factor, which has a great deal of influence on earning competitiveness in global business environment. There are conflicts among all members of the SCM. In order to maximize the total profit of the SCM, negotiation among all members is necessary. For enterprise in the supply chain, the supply chain partnership has become a significant factor affecting firm performance. In this paper, I examine the impact of cooperation between enterprise and its supply chain partners. Specifically, I collect survey data from Chinese manufacturing firms about their relations with partners and use regression analysis to test hypotheses about the associations between firm performance and supply chain partnership. My results support that superior supplier partnership has a positive impact on reducing transaction costs and improving financial and market performance. In additional test, I establish a series of models with interactive terms.
