This paper aims to present spot pattern welding (SPW) as a scanning strategy for laser-foil-printing (LFP) additive manufacturing (AM) in place of the previously used continuous pattern welding (CPW) (line-raster scanning). The SPW strategy involves generating a sequence of overlapping spot welds on the metal foil, allowing the laser to form dense and uniform weld beads. This in turn reduces thermal gradients, promotes material consolidation and helps mitigate process-related risks such as thermal cracking, porosity, keyholing and Marangoni effects.

304L stainless steel (SS) feedstock is used to fabricate test specimens using the LFP system. Imaging techniques are used to examine the melt pool dimensions and layer bonding. In addition, the parts are evaluated for residual stresses, mechanical strength and grain size.

Compared to CPW, SPW provides a more reliable heating/cooling relationship that is less dependent on part geometry. The overlapping spot welds distribute heat more evenly, minimizing the risk of elevated temperatures during the AM process. In addition, the resulting dense and uniform weld beads contribute to lower residual stresses in the printed part.

To the best of the authors’ knowledge, this is the first study to thoroughly investigate SPW as a scanning strategy using the LFP process. In general, SPW presents a promising strategy for securing embedded sensors into LFP parts while minimizing residual stresses.

The purpose of this paper is to investigate the efficiency of Korean insurers that have adopted enterprise resource planning (ERP) system to improve their efficiency.

The study uses Data Envelopment Analysis (DEA) with several inputs and outputs to measure both technical and scale efficiency. With the efficiency measures and using the ordinary least square with the hetereoscedacity consistent standard errors, the study further investigates the factors affecting efficiency, and the association between ERP and efficiency.

This study finds a strong positive association between ERP implementation and the insurers’ efficiency and profitability. However, firms may experience a decrease in efficiency and profitability during the first and second year after ERP implementation.

Although the findings of this study are consistent with extant studies, the study’s findings may lack generalizability because the samples are limited small Korean Property/Casualty (P/C) insurers.

This study investigates the impact of ERP implementation on P/C insurers in an emerging market.

This paper's objective is to provide improvement plans that take into account problems in the housing sector, as well as low fertility and demographic problems caused by aging, by suggesting long‐term policy directions considering all future possible changes in fertility and housing policies.

This research analyzes age specific fertility rates by socioeconomic index, composition of three scenarios about the total fertility rate, the forecast of the future population by the cohort component method, and the forecast of housing demand according to the Mankiw‐Weil (M‐W) model.

If the fertility rate increases through improvements in socioeconomic conditions, then we see that housing demand also increases. If the fertility rate level is higher than that of scenario 3, then a housing demand decrease comes later. However, even if the low fertility rate issue is addressed, the problem with the housing market due to the aging is expected to continue for the time being.

If the population decrease cohort is accumulated due to the continuously low fertility, then it will cause an increase in the reduction effect of housing demand. Considering housing spaces, the elderly require a relatively large amount of available space in Korea where the aged population is rapidly increasing. This increase in seniors could counterbalance the reduced demand for housing.

This is a long‐term‐oriented paper about housing demand and the changing trends in Korea, which is undergoing demographic changes due to low fertility and ongoing aging. We need to monitor fertility rates and the structure of population changes to achieve a stable housing market, and we should also recognize that these structural changes by age will have diverse ripple effects on housing demand.

Throughout history, from ballads to requiems, music has played an important social role in reflection on mortality. Not only do musicians articulate their angst and thoughts about death, but, in so doing, they enable listeners to explore their own feelings. While the relationship between music and mental health can be examined from a number of perspectives, two broad approaches can be taken: artist-centred approaches and listener-centred approaches. The first analyses the life and work of artists, focussing particularly on the ways in which they explore death and angst in their music. The second looks at the ways in which the life and work of an artist is interpreted by listeners. Within these general approaches, a complex set of questions emerge – often at the interface of both approaches. How is the music used by listeners in their reflection on mortality? How is music used to manage mental health? Does reflection on the life and work of an artist contribute to suicidal ideation? Is the reception of music altered by an artist’s suicide? Using both these approaches and drawing particularly on the work of Émile Durkheim, this discussion demonstrates the significance of popular music analysis for death studies, focussing particularly on the issues surrounding popular music’s relationship to suicidal ideation.
