An increasingly important facet of software development is the ability to estimate the associate cost and effort of development early in the development life cycle. Most of the proposed models are based upon a combination of intuition, expert judgement, and regression analysis of empirical data. Overall, the work has failed to produce any single model that can be applied with a reasonable degree of success to a variety of environments. This paper presents a neural network (NN) model that related software development effort to software size measured in function element types. The heuristic approach is applied to decide the number of hidden neurons in NN from the relationship between input-output pairs. The research describes appropriate NN modeling in the context of a case study for 24 software development projects. Also, this paper compared the NN model with a regression analysis model and found the NN model has better accuracy.

The relationship between education and work is of the greatest concern to individuals and society because they are the key drivers of growth and development. In the context of Industry 4.0, labor and educators are facing the challenges of big changes in the workplace. How to prepare undergraduate students for the world of employment has become the most important mission of higher education providers. This paper explored the competency gap in the labor market in Vietnam from the perspective of employees who have been dissatisfied with the current status. First, a qualitative method with the Delphi technique was applied to confirm this consensus in an employees' competency model. Then, the satisfaction level for each competency criterion was explored by applying the advance quantitative method, namely, best non-fuzzy performance approach. Lifelong learning was ranked first, followed by creativity and innovation, foreign languages, expertise and digitalization, adaptability, and finally, organizing and managing ability. Critical thinking and problem-solving were perceived to have the biggest gap. The order of competency satisfaction is useful in explaining the mismatch between education quality and labor market demand. The findings provide valuable guidelines for education managers who seek to bridge the competency gap and improve education quality.

The present study aims to apply the theory of Brecht's 'Verfremdung' or distancing effect to the process of fashion design. The distancing effect refers to an avant-garde artistic technique that enables artists to create their works by viewing particular objects separately from the phenomena that occur around those objects. Brecht encouraged a sense of purpose that involved shifting to the new society sought by modernism. He also suggested an artistic approach that isolates perception from judgment 'Verfremdung' which reflects his approach well. In this paper, with the distancing effect considered as a method for creation, the author identifies the system of thought associated with the distancing method and applies this system to fashion design. To this end, the author first reviewed the concepts of 'Entfremdung' (alienation) and the distancing effect and studied the backgrounds of the two concepts. Next, the author identified Brecht's epic theory and its application. As a result, a method of perceiving objects as used with the distancing effect was noted, and this method was utilized to distinguish the relationship between the body and its clothes. Specifically of interest were parts of the human body and the related functions of clothes as well as the motor functions of the body and detailed decorations on clothes. Moreover, the author discovered a trend in the wearing of clothes that exists in the context of historical changeability by examining Brecht's work as it relates to the types of clothes that are worn. Finally, the author applied the distancing effect to fashion design in consideration of the discovered trend.

The number of industrial accident victims in the construction industry accounts for 1/3 of those in the entire industries and about 30% of the total compensation costs are spent in the construction industry. As such, the construction industry is a typical industry causing numerous safety accidents. This study analyzes the status of industrial accidents in small scale construction sites to build maximum five-story buildings by examining statistical data for the past five years, investigating those construction sites and conducting interviews with the workers. This study also seeks the causes of and measures for industrial accidents in the small scale construction industry through comparison with relevant systems. The findings are as follows: (1) To reduce hazard rate, shaping the working environment and safety measures that take into account the physically weak classes of the middle aged and the aging are urgently required, because 62.9% of the industrial accidents in the construction industry occurred to those who are 50 years of age or older. (2) The hazard rate at small scale construction sites with less than 10 construction workers accounts for 55% of that of the entire industries. The government, in this context, needs to support finance or technology and improve system by selecting the small scale construction sites, where industrial accidents occur frequently. (3) Because the hazard rate of unskilled workers with less than 6 months of work experience accounts for 90.95% of the total, safety education needs to be concentrated on those unskilled workers. (4) The relevant standards need to be segmented and revised and bolstered, given that 64.79% of death disaster in the construction industry occurs in the temporary structures including scaffolds and ladders.

Large access providers (ISPs) are seeking for new types of business agreements and pricing models to manage network costs and monetize better the provision of last-mile services. A typical paradigm of such new pricing norms is the proliferation of paid peering deals between ISPs and content providers (CPs), while on top of this, some ISPs are already experimenting with usage-based tariffs, usually through data-plans, instead of the typical fixed-based charging. In this work we define as common platform, the infrastructure in which a single ISP transacts with several CPs through peering agreements. In this context, we examine whether, and under which market conditions, the profitability of the involved stakeholders improves when the establishment of this platform is accompanied by a monetary compensation from the CPs to the ISP (paid peering), v.s. a scenario where their deal is a typical settlement-free one. In both cases, we assume that the ISP implements a usage-based access pricing scheme, implying that end-users will pay more for higher transaction rates with the CPs. Our framework captures some of the most important details of the current market, such as the various business models adopted by the CPs, the end-users' evaluation towards the ISP's and CPs' level of investments and the traffic rates per transaction for the offered services. By analysing the equilibrium derived by a leader-follower game, it turns out (among other practical takeaways) that whether or not the profitability of a CP improves, it highly depends on whether its business model is to sell content, or if it obtains its revenue from advertisements. Finally, we extract that consumer surplus is considerably higher under paid peering, which in turn implies improved levels of social welfare.

The glass ceiling is defined as a barrier so subtle that it is transparent, that it prevents women and minorities from moving up in the management hierarchy. Individuals in the minority may perceive the presence of a glass ceiling within their social context, a barrier put in to place by those in the advantaged majority. This study has testified pragmatically the influence of glass ceiling perceived by the female employees of travel agency on their work attitudes(organizational commitment, turnover intention). Data were collected by 202 full time female employees. The results of analysis is as follows: First, it is revealed that glass ceiling has no influence on turnover intention. Second, this study show that the higher glass ceiling is perceived by the female employees of travel agency, the more they have negative influence on their affective commitment. Contrary to our expectation, however, it is revealed that glass ceiling has no influence on continuance commitment. That is, glass ceiling have significant effects on affective commitment whereas the effects are not significant for continuance commitment. Third, affective commitment have significant effects on turnover intention. However, it is revealed that continuance commitment has no influence on turnover intention.

Split-tee connection with High Strength Bolts is normally used in low and middle rise buildings in Europe because the structural efficiency and installation work of connections are excellent. However, the domestic situation is different from that in Europe. The analysis and the design for the T-split connection are complicated, because the structural behavior often T-split connection with High Strength Bolt is governed by so many parameters, i.e., prying action, bolt's tension, shear failure and plastic failure of flange plates. Many researches regarding the structural behavior of the split-tee connection have been undertaken in other parts of the world, such as the, Americas, Japan and Europe, but in the domestic context, this is a pioneering study. Therefore, the purpose of this paper is to supply basic data for the design of T-split connection, and to verify the structural characteristics that define reactions to prying action, based on an experimental study.
