Abstract

Purpose

The purpose of this paper is to investigate the predictors of game addiction based on loneliness, motivation and inter-personal competence using the samples of college students recruited from South Korea (n=251).

Design/methodology/approach

The authors examined the underlying mechanism of game addiction by testing a moderated mediation model, in which inter-personal competence moderated the mediation model of loneliness, regulatory focus and online game addiction. First, the authors clarified the relationship among loneliness, motivation and inter-personal competence, to understand the influences of loneliness on other variables in this study (mediation test). Second, the authors examined the underlying mechanism of game addiction by testing a moderated mediation model, in which inter-personal competence moderated the mediation model of loneliness, regulatory focus and online game addiction (moderated mediation).

Findings

Regulatory focus mediated the effect of loneliness on online game addiction. Moderated mediation analyses using PROCESS confirmed that inter-personal competence significantly buffered the indirect effect of loneliness (through regulatory focus) on online game addiction. The findings indicated that inter-personal competence accounted for significant differences in the mediation models.

Originality/value

This study bridges the gap in the online game addiction literature by explaining how loneliness is associated with online game addiction.

Abstract

Purpose

Gut microbial changes are associated with diseases such as obesity and type 2 diabetes and may be influenced by diet patterns. Thus, this paper aims to investigate the effects of alcohol, sodium chloride (NaCl) and dietary restriction on the composition of the gut microflora.

Design/methodology/approach

Five-week-old male C57BL/6N mice were orally administered by gavage with ethanol (ET; 4 g/kg), 200 µL of 6% NaCl (NC), or equivalent volumes of phosphate-buffered saline (ET-control and NC-control) every two days for 10 weeks. The mice were also orally administered by gavage with the recommended diet (RD-control; 3 g per mouse per day), or with 40% (RD-40) or 60% restricted level (RD-60). DNA samples obtained from mice ceca were sequenced using the Illumina MiSeq Sequencing system; raw data were analyzed using BIOiPLUG software.

Findings

This study shows that high ethanol and NaCl consumption, and diet restriction can change the composition of the intestinal microflora, especially Akkermansia muciniphila in ET (p = 0.0050) and NT (p = 0.0366) groups. In addition, the ratio of Bacteriodetes/Firmicutes and the diversity of microflora were generally reduced (p = 0.0487-0.4929).

Originality/value

These results raise the possibility of a relationship between diet patterns, change of intestinal microbiome and disease, which must be further evaluated.

Abstract

It is commonly recognized that the transition to democracy in Korea was associated with economic progress. However, not many scholars have given attention to the role of bureaucracy during the process of democratization, due to the fact that bureaucracy is usually thought of as belonging to politics, not democracy. As a refutation of this general view, first, this chapter argues that bureaucracy has been an important contributor to political modernization. Since the post-1945 period, the ‘ceiling’ strategy, which limits the total number of civil servants, was introduced into the personnel management method and system of checks and balances to limit undue political influence over staffing and to control bureaucratic expansion. Second, through this strategy as policy, the bureaucracy legitimately tried to avoid undemocratic political power by standardized process and allow coordination. The ceiling policy is originally the product of historical context during colonial and authoritarian period, but the bureaucracy utilizes it as the instrument to reduce corruption. The contribution of this chapter is provoking the new insights about democratization from bureaucrat’s perspective which is rarely highlighted.
