본 논문에서는 각 축 방향으로 절대값을 취해 더하는 형태의 맨해튼 거리 측정법을 일반화하 여 2차원 및 3차원에 대한 거리 측정 방법을 제시한다. 또한 이를 이용하여 Worley 노이즈 함수에 적용하여 구현하는데 이용한다. 기존의 방법으로는 2차원에 대해서만 계산이 가능했으 나 제안된 방법에서는 2차원과 3차원에 모두 적용 가능하다. 또한 새로 제안된 방법을 사용하 면 맨해튼 거리를 사용하는 Worley noise함수에 적용할 경우 더 광범위한 패턴 변화를 줄 수 있다. 또한 거리 개념은 매우 다양한 분야에 사용하는 기본 개념이므로 이를 일반화하는 것은 매우 중요한 의미를 가진다고 할 수 있다. 기존의 맨해튼 거리가 2차원에 대해서는 마름모 형 태와 3차원에 대해서는 8면체의 형태로 나타나는 점에 착안하여 이를 확장하고자 한다. 제안 된 방법에서는 매우 간단한 방법을 사용하여 2차원과 3차원에 대해 기존의 유클리드 거리와 맨해튼 거리 개념을 확장하여 일반화된 거리 개념을 제시한다. 이러한 확장된 거리 개념을 Worley 노이즈 함수에 적용함으로써 더 풍부하고 다양한 형태를 얻을 수 있으며 이에 따라 Worley 노이즈를 기반으로 한 프로시저럴 텍스처 패턴 또한 더 다양한 결과를 생성할 수 있 게 된다. 본 연구에서는 새로 제안된 방법을 사용하여 얻을 수 있는 패턴을 실험하여 기존의 거리 개념에서 얻을 수 있는 패턴의 확장된 결과의 예시를 보여줌으로써 제안된 거리 계산 방 법의 유용성을 확인할 수 있도록 한다.

The purpose of this study was to develop the Functional golf inner-wear by preventing the injuries and enhancing the performance of the Golf swing by checking the influence of the wearing of the functional golf inner-wear considering golf characteristics on the Swing trajectory and Shot distance. Functional inner-wear effective for golf swing was manufactured using the sports taping method. Changes in driver and iron swing before and after wearing the functional golf inner-wear manufactured in this way were measured using trackman equipment. Measurement variables were limited to Club Speed, Attack Angle, Club Path, Ball Speed, Smash Factor, and Priority. Before and after wearing functional golf inner-wear, there were statistically significant differences in driver club speed, iron club speed, driver etch angle, iron club pass, driver ball speed, driver smash factor, iron smash factor, driver carry, iron carry, and right shoulder joint proprioceptive sensory ability. As a result, functional golf inner-wear is effective for ball speed, impact, and carry by increasing club speed and efficient swing. Future research will focus on the development of functional golf that can improve the swing ability in a short game that plays an important role in the golf game through various sports taping grafting technique, textile, special material, film, Research on functional golf inner-wear.

Korean historical literatures offer numerous records on astronomical phenomena such as eclipses, comets, and close approaches, etc. Records of close approaches often use specific terms to describe the angular distance, which lack translation into modern numerical values. We study the usage of the five commonly used terms, namely, Entry (入, En), Invasion (犯, In), Occultation (掩, Oc), Eclipse (食, Ec), as well as the unit Chi (尺). Our analysis is based on more than 2,300 records from Goryeo (918–1392 CE) and Joseon (1392–1910 CE) Dynasties. Through statistical analysis, we determine their quantitative definitions. We convert the lunisolar calendar to the Julian and Gregorian date and utilize the modern ephemeris DE431 to calculate the angular distance between celestial bodies. We find that the angular distances of the terms En, In, Oc, and Ec correspond to respectively 1.78◦+2.36 −1.11, 0.89◦+3.54 −0.51, 0.44◦+1.15 −0.31, and 0.29◦+2.61 −0.16 for the Goryeo Dynasty and 1.36◦+1.15 −0.64, 0.51◦+1.11 −0.32, 0.25◦+0.27 −0.17, and 0.21◦+0.25 −0.11 for the Joseon Dynasty. Additionally, we determine the angular size of the unit Chi by using the records from Korean chronicles along with the drawings of comets’ tails in the Daily Log (天變謄錄). We estimate the unit Chi to be 1.11◦+0.46 −0.40 and find that the numerical definition was consistent throughout the two dynasties in Korea. Furthermore, we find that the terms were used to describe the closest approach and that there is no observational bias in the angular distances against the apparent magnitudes of the objects. We show that the terms En, In, Oc, and Ec represent decreasing angular distance in that order and this ordering was consistent in both dynasties.

Abstract Purpose : The purpose of this study is to evaluate the differences and reliability of various methods for measuring Interpupillary Distance. Methods : The participants were 50 Cambodian adults (28.08±3.85 years old) without ocular disease and abnormal binocular vision. Far/near IPD was measured using Corneal reflection pupillometer, PD ruller and spotting, and calculated formula for fixation distance. Using each method, the pupil distance of both eyes was measured three times, respectively, and the average value was recorded. Results : The average value of the corneal reflection pupilometer in the distance was 63.08±3.42 mm, the average value of PD calculated formula was 62.97±3.41 mm, the average value of the PD ruler was 63.72±3.17 mm, and the average value of the spotting method was 63.89±3.15 mm. The average value of the corneal reflection pupilometer in the near was 59.85±3.23 mm, the average value of the calculated formula for fixation distance was 59.95±3.23 mm, the average value of PD ruler was 59.72±3.29 mm, and the average value spotting method was 59.47±3.23 mm. Comparison between various methods in the distance and near showed statistically significant differences (p<0.001). Conclusion : In the comparative analysis between each method, the corneal reflection pupillometer is considered to be the most accurate method, but since there is no significant difference from the average value of the Spotting method, the PD Ruler Viktorin method, and the calculated formula for fixation distance, whichever method is used, it is clinically acceptable. Therefore it is believed that each method is compatible with each other. Key words : Corneal reflection pupillometer, PD meter, PD ruler, Spotting

최근 여러 연구에서 Hg2+에 선택적으로 반응해 형광을 강화시키거나 소광시키는 thiophene을 기반으로한 probe가 많이 개발되어 왔지만, 이에 따른 분광학적 현상에 대한 정확한 분자적 수준의 이론적 해석이 이루어지지 않 았다. 이에 따라 우리는 Hg2+와 thiophene간 상호작용을 면밀히 분석하기 위해 Hg2+와 thiophene간 거리에 따른 에너 지 포텐셜을 구하였다. Hg2+ 이온에 대한 모든 전자(all electron, AE) basis set인 x2c-TZVPPall와 effective core potential (ECP) 기반인 LANL2DZ는 모두 상대성 효과가 고려된 바닥 상태에서 Hg2+와 thiophene이 결합력이 없이 해 리가 되는 에너지 포텐셜을 보여주었지만, 용매인 물이 고려된 시스템에서는 Hg2+와 thiophene이 결합력을 가지는 것 을 보였으며 이것은 실험적인 결과를 잘 재현하는 것이었다. 따라서 Hg2+ 이온을 포함하는 착화합물 시스템에서 올바 른 에너지 상태를 구하기 위해서는 상대성효과와 더불어 solvent 영향도 잘 고려돼야 함을 알 수 있다.

본 연구의 목적은 상사의 변혁적 리더십이 부하들의 발언행동에 영향을 미치는 메커니즘을 이해하기 위한 것이다. 구체적으로는 변혁적 리더십과 발언행동의 영향관계에서 심리적 임파워먼트의 매개효과와 권력거리 성향의 조절효과를 검증하는 것이다. 특히 군 조직에서 수직적인 관계의 중요성이 상당히 크다 는 것을 고려하면 직속상사의 리더십은 부하의 발언에 더 큰 영향을 줄 것이다. 권위적인 군 조직의 특수성은 민간조직에 비해 위계질서가 매우 엄격하므로 발언행동에 대한 메커니즘과 영향이 다르게 나타날 수 있다. 이 연구의 대상은 위계적 조직인 육군의 부사관 및 장교들을 대상으로 하였다. 응답한 517개 표본 중 불성실한 표본 64개를 제외하고 453개의 유효한 표본을 분석에 활용하였다. 자료분석은 기술통 계, 상관관계 분석, 구조모형 검증을 통해 실시하였다. 연구를 통해 다음과 같은 결과를 도출하였다. 첫째, 변혁적 리더십은 발언행동에 통계적으로 유의한 정적 영향을 미치는 것으로 나타났다. 둘째, 변혁적 리더 십과 발언행동 영향관계에서 심리적 임파워먼트는 매개효과를 갖는 것으로 확인되었다. 셋째, 변혁적 리 더십이 발언행동에 미치는 영향을 권력거리 성향이 조절한다. 넷째, 변혁적 리더십이 심리적 임파워먼트 에 미치는 영향을 권력거리 성향이 조절한다. 본 연구 결과를 바탕으로 군 조직의 HRD 담당자에게 시사 할 수 있는 실무적 내용을 논의하였고, 연구의 한계 및 향후 연구방향을 제시하였다.

목적 : 신체균형 측정기를 이용하여 주시거리와 다양한 시각 상태가 신체 안정성에 미치는 영향을 알아보고자 하였다. 방법 : 대상자는 총 23명(23.92±2.09세)으로 진행하였으며, 시각 조건은 모두 ‘완전교정, 흐림 조건(시력 0.5 logMAR 미만) 그리고 10° 이내의 시야’이다. 신체 안정성 측정은 ‘3D Guidance‘를 사용하였다. 결과 : 완전교정 상태에서는 주시거리 간 통계적으로 유의한 차이는 없었다(p>0.050). 그러나 흐림 조건에서는 주시거리에 따라 측면 및 전·후면 흔들림에서 유의한 차이가 확인되었으며(p=0.004, p=0.027), 시야가 10° 이 내로 제한되었을 때에도 유의한 신체 흔들림이 관찰되었다(p<0.050). 결론 : 주시거리에 따라 신체 안정성의 변화가 나타나며, 특히 흐림과 제한된 시야 상태에서는 주시거리에 따른 차이가 더 유의하였다.

Distance is a fundamental definition in fields such as geometry, mathematics, and physics. Because it is a very fundamental metric, it is not easy to create a new definition. In this study, we analyze existing distance definition and propose to generalize Euclidean distance and Manhattan distance, which are mainly used distance metric in existing distance definition. We analyze the definition of Minkowski distance, which is previously used as a concept of generalization along with Chebyshev distance, and the disadvantages of using this distance metric. By introducing a new perspective that interprets the existing Manhattan distance as a distance measured in four axes rather than simply adding the distances in each axis direction, this research introduces a new distance metric in two dimensions. This is a metric that generalizes the Euclidean distance and the Manhattan distance, and the proposed distance metric is derived from a geometrical aspect and an algorithm for calculating it is presented. We applied the existing distance definition and compared the differences through the results of generating a Voronoi area by the shortest distance from randomly distributed points in two dimensions. It is expected that the proposed method can be applied and expanded to the field of various graphics algorithms that use the distance metric.

AI recommendation service is adopted in consumption consulting such as high-tech and fashion consumption (Thapliyal & Ahuj, 2021). Now, for high-tech and fashion products, the advance selling strategy is widely adopted. Thus, this study targets to detective the consumers’ preference toward AI agents comparing human agents under advance selling and spot selling. The independent variable of this study is consumption type: Pre-sale Products vs. Spot Products. Pre-sale Products are quite popular currently, especially technological products. Construal-level theory (CLT) offers a valuable framework to explain the mechanisms that trigger evaluations, predictions, and behaviors by linking the degree of mental abstraction (the construal level) to psychological distance (Trope & Liberman, 2000; 2003; 2010). Four dimensions including temporal, special, social, and probability distance are argued to present the psychological distance (Trope et al., 2007). Liberman et al. (2022) discuss the time distance and argue the distant-future events are represented in a more abstract, structured, high-level manner than near-future events. Kim & Duhachek (2020) draw on a dimension of persuasion by AI agents to posit that AI agents are perceived as low-construal agents because of the fact that people hold a lay theory that AI agents do not have superordinate goals and cannot learn from their experiences or possess consciousness like humans do. Consequently, they find that individuals perceive greater appropriateness and are more persuaded when an AI agent’s persuasive messages highlight low-construal as opposed to high-construal features. Moreover, consumers prefer abstract information related to a certain product rather than concrete information when a purchase is to take place in the distant future or when construal levels are high (Hernandez et al., 2015). Thus, this research hypothesizes: When consumers buy pre-sale products (vs. spot products), human agents will be the more favorable service provider than AI agents since the consumer is under a high level of construal. This research proposes to adopt a 2 (Advance Selling vs. Spot Selling) x 2 (Short Psychological Distance vs. Far Psychological Distance) x 2 (AI Agents vs. Human Agents) between groups experimental study to test the main effects and mechanism (H1). Furthermore, this study would identify the key moderating effects to discuss the boundary effects of the mechanism for establishing marketing strategies with AI services for managers.

The original third places concept conveyed the offering of much-needed settings for social comfort, thereby complementing the absence of equal opportunities at home (1st place) or in the workplace (2nd place). 3rd place is a crucial term to connect customers’ social needs, perception of service encounters, and the service provider’s managerial operation. Following the Covid-19 outbreak, various distancing forces have impeded previously intense social interactions featuring human-human contact. The increased use of contactless services and social distancing measures has impacted these. Such measurements refer to mandatory actions to maintain a fixed physical distance from others (i.e., two meters or six feet) via seating arrangements or suggested signage. While such compliance practices successfully limited the spread of Covid-19, they were also a signal of regulated behaviors and acceptable personal boundaries. The current study addressed this question by conducting experiments in three scenarios: a café, restaurant, and sports stadium. Following Pine and Gilmore’s experience typology, the three represent a passive absorptive experience, an active absorptive experience, and an immersive experience.

Algorithms are rapidly altering the way society operates (SIOP, 2020). Algorithms are used in modern businesses for tasks such as hiring, advising investors on financial matters, recommending new products to customers (Shankar, 2018). However, lay people frequently oppose them, a phenomenon known as algorithm aversion (e.g., Dietvorst et al., 2015). While prior research tries to address this issue by identifying cognitive and affective predictors of algorithm aversion, we seek to contribute to the algorithm aversion literature by investigating an understudied antecedent of people’s support for algorithm adoption—their cultural values (Dietvorst & Bartels, 2022).

Negative brand events can significantly harm the brand, affecting consumer cognitions, emotions, and behavior, leading to negative brand evaluations, negative emotions, brand avoidance, and retaliation. Thus, it is critical for brands to design and implement strategies that promote consumer forgiveness to mitigate those negative consumer responses. Despite the growing literature on the determinant factors of consumer behavior in a brand failure context, there is still scarce evidence regarding the impact of brand type on consumer responses, including consumer forgiveness, following a negative brand event. Considering that consumers tend to react differently to a brand perceived as arrogant (making them feel inferior), as opposed to a brand they strongly identify with, this paper focuses on failures of equal vs. higher status brands and investigates their impact on consumer forgiveness. Following the above, we expect that differences in brand status can shape consumer behavior following a failure or transgression.

B2B marketers increasingly encounter a pressure to be digitally present in digital channels and to generate content that is tempting in driving potential customers to interact with the company online (Wiersema, 2013; Andersson & Wikström 2017). This is what B2B lead nurturing is about as the objective of lead nurturing is to provide the audience with relevant and valuable content which leads to an increased brand interest and awareness, with the goal of bringing in new customers (Marketo, 2023). To better understand how prospects and leads react to digital content, companies can build lead scoring into a strategic tool for the salespeople to qualify the prospective customers down to a list of leads, meaning prospects who are considered the most likely to convert to a positive business outcome and to be contacted in person by the salespeople (Järvinen & Taiminen 2016; Paschen et al. 2020).

Customer experience is a top priority for business executives and a competitive ground for marketing. Business-to-business (B2B) customer experience is more intricate as it involves multiple actors with distinct roles and objectives, necessitating more customization and knowledge. Hence, it is paramount for organizations operating in the B2B space to understand and enhance the customer experience to gain a competitive edge. This complexity is further amplified in cross-border settings where partners face additional differences and distances, requiring even more mutual adaptations than in domestic business interactions. In such scenarios, individuals involved may significantly differ in terms of culture, language, and business practices.

진해만은 태풍 내습 시 피항 선박이 폭주하고 강한 바람 등의 영향으로 주묘가 자주 발생하며 이에 따른 선박 간 충돌 및 좌초 등 해양사고 발생 개연성이 매우 높다. 본 연구에서는 우리나라 해역 특성에 맞는 진해만 정박지의 선박 간 안전이격거리 설정을 위한 연 구를 수행하였다. 진해만 태풍 피항지에는 태풍 내습 시 평균 100 ~ 200여척의 선박이 정박을 하고 있으며 풍속이 25m/s 이상되는 강한 외력에서 전체 선박의 약 70%에 주묘가 발생하는 상황인 것으로 분석되었다. 본 연구에서는 국내외 설계기준 상 제시된 황천 시 정박 선 박간 이격거리, 실제 피항지로서 사용된 진해만 피항선박 간 이격거리, 강한 외력에 따른 선박 표류 시 적정 안전거리 등을 분석하여 제 시하였다. 그 결과 설계기준 상의 최소 기준과 비상조치 시간을 고려하여 약 400 ~ 900m의 안전이격거리가 필요하며, 공간상의 여유가 있 는 경우에는 700 ~ 900m 이격거리 설정이 필요한 것으로 도출하였다. 본 연구의 결과는 향후 진해만 피항지를 이용하는 선박에 대해 선박 간 안전 이격거리를 위한 지침 수립 시 활용이 가능할 것으로 기대된다.
