Interaction format effects in consumer–AI interactive advertising: the role of context alignment in persuasive interaction effectiveness
Abstract AI technology is increasingly integrated into advertising, enabling advertisers to deliver persuasive messages through interactive communication with consumers. Drawing on perceived interactivity theory, this study categorizes consumer–AI persuasive interaction formats into three types—personalization, delegation, and value-in-use—and examines their effectiveness across decision-making contexts.

Improving non-expert performance in musculoskeletal MRI protocoling through a large language model - Scientific Reports
Abstract MRI protocoling, the process of selecting appropriate sequences, is especially complex in musculoskeletal (MSK) cases. This study evaluates whether a large language model (LLM) can effectively assist non-experts in MRI protocoling. We collected two retrospective datasets of musculoskeletal (MSK) MRI orders: (1) a prompt-development dataset (Jan–Dec 2023; 538 cases) and (2) a testing dataset (Jan–Jun 2024; 107 cases).

Percolation-Limited Threshold Switching in Strain-Graded Mott Devices
Introduction Click to copy section linkSection link copied! Emerging materials with a metal–insulator transition exhibit finely tunable electronic phases in response to various stimuli (e.g., strain, (1−3) doping, (4−6) and temperature (7,8)), enabling the dynamic modulation of electronic states and the realization of novel material functionalities.

Strain Partitioning at the Oxide Interface for the Isothermal Phase Transition in Freestanding Tri‐Layers
1 Introduction The emergent materials featuring metal-insulator transition (e.g., VO2 and NbO2) have attracted attention due to the complex interplay between the charge-orbital-lattice degree of freedom by strongly correlated d-band electrons; small external stimuli cause the dramatic transition to distinct electronic phase, leading to abrupt resistance change associated with the first-order metal-insulator transition.[1-6] Among the stimuli, the (mechanical or chemical) stress modulates...
Human immunodeficiency virus-1 induces host genomic R-loops and preferentially integrates its genome near the R-loop regions
eLife Assessment This study presents two main findings regarding HIV-1 genomic integration. The first, based on convincing evidence in primary cell models, is that HIV-1 induces R loop formation, though the viral driver of this process remains undefined. The second, based on model cell systems with limited physiological relevance to HIV-1, is that a portion of HIV-1 genomes integrates in the vicinity of where R loops form.
Assessment of safety through mutagenicity and subchronic toxicity studies with black pepper extract preparation
Evaluations All animals were observed at least twice daily for viability. Cage-side observations of all animals were performed daily during the study. On Day 0, prior to the first treatment with the BPE, and weekly thereafter, a detailed observation was conducted while handling the animal, generally occurring on days that the animals were weighed, and food consumption measurements taken.

Human immunodeficiency virus-1 induces host genomic R-loop and preferentially integrates its genome near the R-loop regions
Abstract Although HIV–1 integration sites favor active transcription units in the human genome, high–resolution analysis of individual HIV–1 integration sites has shown that the virus can integrate into a variety of host genomic locations, including non–genic regions.
Negative Screening AI in Ankle Stress Radiography to Reduce Workload
Interpreting ankle stress radiographs is subjective and time-consuming. We aimed to train an AI model that efficiently screens negative cases, assess the agreement with expert with and without AI-assistance, and compare the workload reduction. We collected anterior draw test (ADT) and talar tilt test (TTT) ankle stress radiographs from Seoul St. Mary's Hospital and St. Vincent's Hospital. Patients with prior surgery, severe joint fusion, or incomplete images were excluded.
Human immunodeficiency virus-1 induces and targets host genomic R-loops for viral genome integration
Abstract Although HIV-1 integration sites are considered to favor active transcription units in the human genome, high-resolution analysis of individual HIV-1 integration sites have shown that the virus can integrate in a variety of host genomic locations, including non-genic regions.

Digital Forensic Research for Analyzing Drone Pilot: Focusing on DJI Remote Controller
7. Findings and Discussion Through this research, we conducted an investigation into the DJI RC, the remote controller for various DJI drones, and proposed digital forensic investigation methods. Firstly, in Section 3, we analyzed various features of the DJI RC, including its connectivity with peripheral devices, the types of internal data, and their storage locations. Table 13 summarizes the data acquisition related to remote controllers in both existing studies and our research.
Comprehensive constitutive modeling and analysis of multi-elastic polydimethylsiloxane (PDMS) for wearable device simulations - Scientific Reports
Abstract Within the field of wearable devices, polydimethylsiloxane (PDMS) has long been one of the most prominent materials utilized. It is therefore unsurprising that demands for its usage has now extended beyond experimental works into computational simulations, particularly those involving finite element method (FEM). To replicate the mechanical properties of PDMS in FEM, an accurate constitutive model is required, preferably one that encompasses wide ranges of PDMS elasticity.
Awesome-runbook, the open-source project for runbook curation
We recently took a big step by launching Runbear. It was an exciting milestone, but not without its challenges. We encountered two primary issues. First, even with the assistance of our generative AI, users still found it challenging to create runbooks, exemplifying the cold start problem. Second, the low execution frequency of our service led to a high pain/gain ratio for our customers. Looking back, we didn't fully adhere to the working backward approach.
런베어 프리시드 투자 유치 이야기
런베어 프리시드 투자를 유치했다! 🎉 축하 겸 자랑은 이 한 줄로 끝내고, 이 글에서는 투자 기간 동안 힘들었던 부분과 배운점 그리고 고마운 마음을 표현해보고자 한다. 투자는 왜 받을까 일반적인 얘기 말고 우리 얘기를 해보자. 런베어를 창업하면서 정했던 원칙 중 하나는 린(Lean)이었다. 채용은 필요한 시점에 꼭 필요한 인재를 모시고, 투자는 목적이 분명한 투자만 유치하자. 생존이 아니라 성장을 위한 투자를 받자. (물론 생존도 성장의 필요 조건이지만, 디테일은 넘어가자.) 그동안 헛살지는 않았는지, 감사하게도 런베어 창업 이후 투자에 관심을 보여주신 소중한 인연들이 많았다. 무슨 사업을 할지도 정하지 않은 상태에서 보여주신 관심인지라 더욱 고마운 제안이었다. 역설적이게도 이런 고마운 제안 덕분에 투자를 더 조심스럽게 접근하게 되었다. 우리를 믿어준 사람들의 소중한 돈을 생각없이 받을 수는 없지 않은가. 좀 더 구체적으로 세운 투자 원칙: 미국 시장 진출에 도움을 받을 수 있는 투자를 유치한다.
Y Combinator 인터뷰 + 탈락 썰
5월 한 달 감정의 롤러코스터를 자유이용권으로 즐겼다. 설렘과 아쉬움, 후회와 배움이 함께했던 한 달이었다. 매우 많았던 사건 중 특히 Y Combinator (a.k.a YC) 인터뷰는 미친듯한 속도감과 더불어 감정의 소용돌이를 가져다주었다. 지난 4월 초 YC에 지원서를 넣었다. 평소 YC 영상을 보며 많이 배워왔기에 YC 지원서를 작성하는 것 만으로도 팀의 성장에 큰 도움이 된다는 것을 알고 있었다. 지원서가 물어보는 그리 많지 않은 질문은 놀랍게도 생각보다 평범하지만 적절히 답을 하려면 꽤나 많은 생각과 정리를 요한다. 특히 YC에서 직접 제안하는 지원서 작성 방식을 따라가다보면 꾸밈을 줄이고 간결하게 표현하는게 이렇게나 어려운 일임을 새삼 깨닫는다. 지원서를 넣었지만 솔직히 어떻게 될지 예측하기 어려웠다. 우리는 이제 막 제품을 런칭한 극초기 스타트업이었다. 어디에선가 100배수에 달하는 지원자가 몰린다는 얘기도 들었다.
만 3개월 스타트업 창업자의 고백
스타트업을 창업한지 만 3개월이 지났다. 우리는 충분히 올바른 방향으로 빠르게 움직였을까. 창업하고 나서 가장 많이 들었던 칭찬은 제품을 정말 빨리 만들었다는 것이었다. 첫 제품인 Elaborate AI는 일주일 만에 개발해서 출시했고, Runbear 는 3주 만에 첫 번째 고객에게 비공개 출시를 했다. 빠르게 움직이기 위해 앵커링 효과(Anchoring effect)를 주의했고, 두려워도 피봇을 감행했고, 출시를 미루지 않기 위해 마음을 다스렸다. 한편 우리가 정말 듣고 싶은 칭찬은 "당신의 제품 덕분에 문제가 많이 해결됐다"는 말이다. 아쉽게도 아직 이 칭찬을 제대로 듣지는 못했다. 빠른 것은 누구나 한다. 우리는 좀 더 올바른 방향으로 빠르게 달릴 필요가 있다. 이 글을 통해 만 3개월 스타트업의 창업자로서 한 분기 동안의 실행을 돌아보고, 실수를 고백하고, 개선점을 정리하고, 잘한 점은 자랑하려고 한다. 우리는 IT 운영을 도와주는 AI 비서, Runbear를 만든다.
어떻게든 남겨보는 2021 회고
연말이 되면 이곳 저곳 - 이라고 쓰고 트위터라고 읽는다 - 에서 Procrastination(i.e 미루는 버릇)이라는 단어가 자주 보인다. 2022년이 8시간도 안 남은 지금, 그 이유가 무엇인지 아주 잘 알 것 같다. 더 미루고 변명하기 전에 일단 키보드에 손을 얹어보자. 내가 먹은 음식을 생각해보려면 365 * 3 끼니를 되돌아봐야 하니 너무 어려울 것 같지만, 내가 읽은 책들은 몇 권 안되니 금세 되돌아 볼 수 있을 것 같다. 올 한 해 내가 읽은 책들이 나의 한 해를 잘 표현해줄 수 있지 않을까? 스타트업 & 비즈니스 스타트업의 정의를 물어보면 다들 조금씩 다를 것이다. 하지만 어느 정의든 성장이라는 키워드는 거의 포함되지 않을까 싶다. 리더십 실리콘밸리의 팀장들에 이어 코칭 리더십과 멀티플라이어까지, 딱 한 문장으로 정리하기는 어렵지만 세 권의 이야기를 관통하는 동일한 흐름이 있다.

Inflammation-free, gas-permeable, lightweight, stretchable on-skin electronics with nanomeshes
Abstract Thin-film electronic devices can be integrated with skin for health monitoring and/or for interfacing with machines. Minimal invasiveness is highly desirable when applying wearable electronics directly onto human skin. However, manufacturing such on-skin electronics on planar substrates results in limited gas permeability. Therefore, it is necessary to systematically investigate their long-term physiological and psychological effects.
