The purpose of this paper is to investigate: first, the effects of a user’s grandiosity on the loneliness of another user on Facebook who detected it in terms of his/her well-being status; second, the mediational role of envy between grandiosity and loneliness; and, third, whether different effects are given on narcissism, envy, and loneliness depending on social or para-social relationships on Facebook.

This study’s focus is to investigate how observing others’ grandiose behaviors impact on individuals’ feeling of loneliness. The authors propose that this relationship is mediated by the feeling of envy. The authors further postulate that social relationships that participants may have with other Facebook users would play a key role in feeling different types of envy (i.e. malicious vs benign). Therefore, the current study employed a 2 (levels of grandiosity: high vs low) × 2 (social relationship: para-social vs social) between-subjects design.

The authors found that one’s grandiosity as reflected on Facebook significantly affects other users’ loneliness through malicious envy. However, no moderated mediation via envy (either benign or malicious) was found within the social relationship group.

Social comparison generated by the use of Facebook was found to have an effect on the user’s loneliness through the mediation of envy. In particular, the possibility that such effects could be triggered in para-social relationships was identified.

The purpose of this paper is to reflect on the efficiency and effectiveness of industrial policies by focusing on the peculiar experience of South Korea. It analyzes Korean structural change from a historical and empirical standpoint, highlighting industrial policy interventions involved in this process. The analysis presented offers important insights to inform the debate on the contemporary industrial policy, identifying specific elements and circumstances that can contribute to mitigate government failures and to improve the effectiveness of public action.

The paper adopts a historical and empirical perspective. Concerning the empirical analysis, a composite indicator to assess the process of structural change of economies is presented. This methodology provides annual rankings based on the different economic relevance of the manufacturing sectors over the period 1963–2012.

The paper shows that industrial policy has been extensively involved in South Korean structural development but public intervention interacted with several other factors, including gradual markets liberalization, education, societal and cultural characteristics and low level of income inequalities. As a result, economic development is conceived as systemic process, namely as the outcome of a balance in the roles played by government, markets and civil society. In this framework, government failures, as inability of the government to respond effectively and efficiently to the general interest of the society, are intimately inherent to the mechanisms that rule the relevant relationships within the system.

In the post-crisis debate, very little attention has been devoted in academic and political debate to the ways to mitigate government failures. By analyzing the historical and recent Korean experience with industrial policy, the paper addresses an issue insufficiently analyzed offering an innovative contribution.

The purpose of this study was to investigate the differences in night eating status according to adolescents’ body mass index (BMI).

This was a cross-sectional study that included a total of 688 middle-school students. The subjects were categorized as underweight, normal weight and overweight according to their BMI, and their night eating intake patterns, night eating menu preference and intake frequency were compared and analyzed.

With regard to their night eating frequency, 39.8 per cent replied almost never, while 24.3 per cent replied once a week and less and 22.5 per cent replied two to three times a week. Among 11 night eating menus, the preference for fast foods, confectioneries, street foods and noodles was significantly higher in the underweight group than in the overweight group. The intake frequency of night eating menus such as fast foods, confectioneries and breads increased in the following order: overweight, normal and underweight group. The underweight group had a higher frequency of night eating, and they preferred to eat snacks more frequently from their night eating menu.

In conclusion, it is necessary to form positive dietary habits including nighttime eating for proper dietary management of adolescents.

This paper aims to study the effects of varying inlet channel angle in a novel microfluidic architecture blood plasma separation ability over range of hematocrit values (5–45%) at multiple flowrates.

CAD designs for both micro architectures were designed in SOILWORKS. In the second step, these designs were imported into ANSYS to perform where meshing, model selection, defining blood as two-phase material and boundary conditions are performed.

Separation efficiency values close to 100% with diluted blood and 65.2% with whole blood were observed. Straight channel inlet design has significantly better performance at high hematocrit levels, whereas at lower hematocrit levels, both designs had almost same outcome. Furthermore, lower flowrates have shown the highest separation efficiency for lower hematocrit levels, whereas at higher hematocrit percentages, higher flowrates have shown better separation effects for both designs. Furthermore, trends obtained for flow ratio and flowrates against separation efficiency are demonstrated.

This study is based on blood modeled as two-phase flow, with the phases consisting of blood plasma as primary phase and red blood cells as secondary particulate phase.

Implications of this study are far reaching for point-of-care health-care systems. A practical system of this numerical study can provide a microchannel device which take very small amount of blood sample to separate it into constituents which can be coupled with detection module to detect a particular disease for which it is designed for. This microsystem can be very beneficial for remote areas where a large hospital facility is far away.

This study has carried out a detailed analysis on the ability of a novel microchannel architecture to separate blood plasma from other blood constituents. Inlet channel angle variation effects are observed over a range of hematocrit percentages. These trends are further investigated for three different flowrates to assess the microchannel design behavior.
