In coastal residential communities, especially along the coastline, flooding is a frequent natural hazard that impacts the area. To reduce the adverse effects of flooding, it is recommended to elevate coastal buildings to a certain safe level. However, post storm damage assessment has revealed severe damages sustained by elevated buildings' components such as roofs, walls, and floors. By elevating a structure and creating air gap underneath the floor, the wind velocity increases and the aerodynamics change. This results in varying wind loading and pressure distribution that are different from their slab on grade counterparts. To fill the current knowledge gap, a large-scale aerodynamic wind testing was conducted at the Wall of Wind experimental facility to evaluate the wind pressure distribution over the surfaces of a low-rise gable roof single-story elevated house. The study considered three different stilt heights. This paper presents the observed changes in local and area averaged peak pressure coefficients for the building surfaces of the studied cases. The aerodynamics of the elevated structures are explained. Comparisons are done with ASCE 7-16 and AS/NZS 1170.2 wind loading standards. For the floor surface, the study suggests a wind pressure zoning and pressure coefficients for each stilt height.

Purpose: The hospitality sector is vital to economic development, especially in metropolitan regions, where hotels are a pivotal factor in drawing in leisure and corporate visitors. Despite the potential advantages of urban hotels, there is a gap in empirical studies on the impacts of eco-friendly interior design on hotel appeal and guest behavior. Therefore, this study aims to fill out the research gap. Research design, data and methodology: This study employed a review of the literature systematically as its research design. The study's data collection technique involves exploring peer-reviewed journals through electronic databases like Scopus, and Web of Science. The present author double-checked the quality of instrument for all usable dataset. Results: Prior literature has stated a strong linkage between green interior design in urban hotels and customer behavior and hotel attractiveness. Using environmentally conscious methods, hotels can enhance the quality of their indoor atmosphere, preserve energy and water supplies, and establish a favorable public perception that appeals to environmentally aware consumers, thereby improving their overall experience and contentment. Conclusions: This study concludes that creating indoor spaces with environmental factors in mind could lead to a more enjoyable and beneficial atmosphere for hotel visitors and adopting a sustainability-oriented approach to hotel design and operations could attract potential customers.

The Personal sense of uniqueness (PSU) is positively associated with subjective well-being and has been recently shown its correlation with happiness, influencing consumer's experience behavior. However, the effects of hedonic and eudaimonic experience on conspicuous and inconspicuous (consumer's need for status and inner fulfillment) are unknown. The purpose of this research is to address a gap existing in the literature by testing the effects of PSU on hedonic and eudaimonic leisure experiences and how happiness leisure experiences effects conspicuous and inconspicuous consumption. The relationships hypothesized in the model are tested using partial least squares structural equation modeling (PLS-SEM) and bootstrapping procedure. Data was gathered using a self-administrated survey, answered by 200 consumers based on consumers' leisure experiences. The findings of this study suggest that (i) PSU positively and significantly influence hedonic and eudaimonic happiness; (ii) the effect of PSU on eudaimonic happiness is higher than in hedonic happiness; (iii) eudaimonic happiness positively and significantly influence conspicuous and inconspicuous consumption; and (iv) hedonic happiness negatively and significantly influence conspicuous and inconspicuous consumption. This study helps fill a gap in the literature by introducing and testing the effect of hedonic and eudaimonic leisure experiences and the relationship between these constructs and PSU and (in) conspicuous consumption.

첨성대의 구조와 현재의 모습에 대한 합리적인 설명을 과학적으로 추론할 수 있는 토대를 마련하고자 첨성대 건립을 위한 새로운 시공방법론을 제안하였다. 이는 기존의 시공방법을 첨성대의 건립에 적용할 경우 가설구조물의 설치 및 운용, 돌을 나르기 위한 기중장비의 설치 및 운용 및 내부 채움 흙의 시공 등에 있어 해결하여야 할 문제와 첨성대 건립 당시 신라인들이 보유하였을 것으로 간주되는 장비 사이의 괴리를 달리 설명할 도리가 없기 때문이다. 나아가 첨성대의 얼개 및 현재의 모습에 대하여 제기되는 기단과 남창구 사이 향(向)의 차이, 원통형 몸통의 일그러진 원형평면, 이웃하는 단 사이의 어긋남, 기울기와 일치하지 않는 각 단 편심의 분포, 외부 수평 수직 줄눈의 완벽한 정렬상태, 내부 채움 흙의 존재 이유 등 여러 가지 의문들에 대한 합리적이고도 과학적 근거가 있는 설명이 필요하였기 때문이기도 하다. 제안된 새로운 시공방법론은 이 모든 문제와 의문들에 대한 명료한 답을 주고 있다. 따라서 제안된 새로운 시공방법론은 첨성대를 축조한 당시의 건축자가 필연적으로 채택하였을 수 밖에 없었던 시공방법에 가장 가까운 건립방법이었을 가능성이 높다고 하겠다. 아울러 현재 첨성대 인근 황남동 일대에 산재하는 크고 작은 고분군의 존재는 이 논문에서 제안된 새로운 시공방법론을 첨성대 건립 당시의 신라인들이 자연스럽게 사용하였을 가능성을 암시하고 있다고 하겠다.

Plasmodiophora brassicae is a major disease threat for Brassica oil and vegetable crop production worldwide. The causal agent is a Plasmodiophorid, which are obligate biotrophic plant-pathogenic protists in the Rhizarian kingdom. Although the Plasmodiophorids include other important agricultural pathogens such as Polymyxa betae, Spongospora subterranea, their biology remains poorly understood due to their intracellular biotrophic life style. I will present the assembled and annotated genome of P. brassicae, with insights into developmental stage-specific. We provide the first genomic data for pathogenic Rhizaria. The exploitation of the life stage specific transcripts will shed light in the understanding of the life cycle at a molecular basis, which will in the long run help to understand and control club root disease. Our data also fill an important gap for the understanding of the eukaryotic tree of life, since this is only the third genome of the eukaryotic kingdom of Rhizaria.

Dynamic data possession verification is a common requirement in cloud storage systems. After the client outsources its data to the cloud, it needs to not only check the integrity of its data but also verify whether the update is executed correctly. Previous researches have proposed various schemes based on Merkle Hash Tree (MHT) and implemented some initial improvements to prevent the tree imbalance. This paper tries to take one step further: Is there still any problems remained for optimization? In this paper, we study how to raise the efficiency of data dynamics by improving the parts of query and rebalancing, using a new data structure called Rank-Based Merkle AVL Tree (RB-MAT). Furthermore, we fill the gap of verifying multiple update operations at the same time, which is the novel batch updating scheme. The experimental results show that our efficient scheme has better efficiency than those of existing methods.

This paper investigates announcement effects of the outward foreign direct investment (FDI) projects of the Korean multinational companies. Although the FDI is considered corporate activity that can provide various benefits beyond financial resources, the most previous research focused on macro analysis such as country-level and industry-level analysis instead of the firm-level study, which is required to decide the investment project from a management perspective. Thus, this study examines the relationship between the outward FDI activities of the Korean corporations and their financial performance to fill the gap in this area.

Trust and perceived usefulness have been variables frequently used by IS researchers to explain consumers' online transaction intention. A group of prior studies have incorporated the two variables simultaneously to build better models to capture the phenomenon. However, the studies have largely ignored the role of trust by replacing trust with trustworthiness. The purpose of this study is to fill this gap. To do this, the study conceptualizes and tests relationships between trust, perceived usefulness and related variables. Based on the study results, the study discusses that trust and trustworthiness are distinct and have causal relationships, the dimensions (ability, integrity, and benevolence) of trustworthiness are related but theoretically distinct, and trust performs a mediating role within its nomological network.
