Live-CD는 리눅스 설치 과정의 번거로움을 없애기 위한 노력의 일환으로써 시작되었다. CD 한 장에 리눅스 커널과 어플리케이션을 모두 넣고 어디서나 간단하게 부팅 가능하도록 한 CD를 말한다. 하지만 Live-CD가 악용될 경우 CD안에 공격을 위한 exploit 코드와 어플리케이션을 넣고 공공기관이나 PC방 등에서 CD 한 장으로 해킹이 가능할 수 있다는 문제점이 발생할 수 있다 Live-CD는 Ramdisk상에서만 동작하며 전원을 끄는 것과 동시에 모든 데이터가 소멸되므로 공격자 추적 또한 불가능하다. 따라서 본 논문에서는 하드디스크를 제외한 모든 저장 장치로 부팅을 할 시에는 관리자 인증 과정을 통해서만 부팅 할 수 있는 Bios 메커니즘을 제안하여 Live-CD를 이용한 해킹을 근본적으로 방지할 수 있도록 한다.

This study aims to understand how an influencer's social and physical attractiveness, background and value homophily influences consumer's emotional attachment, which in turn causes user stickiness with regards the influencer's live commerce. We tested all proposed hypotheses among users of the online shopping platform "TaoBao". Ultimately, 297 questionnaires were collected by means of an online survey. The results revealed that social and physical attractiveness positively influence emotional attachment. Meanwhile only value homophily significantly affected emotional attachment, whereas background homophily did not significantly affect emotional attachment. Additionally, emotional attachment was found to significantly influence live commerce stickiness. We also investigated the moderation effect of perceived beauty trends of products sold on live commerce, where the results indicated that high beauty tends to have a higher effect on live commerce stickiness behavior. Lastly, theoretical and managerial implications have been offered.

During the last decade, social live streaming service like Periscope, Ustream, and YouNow has developed from a niche market into a mainstream activity. In this media environment, social live streaming service has a tremendous impact on the social behaviors of users. Despite the rapid development, there are a lack of studies to make better understand the media environment changes through social live streaming service. This study adopted an affordances approach that leads us to identify six distinctive social affordances (visibility, accessibility, information sharing, social interaction, role-taking, interactive revenue) for user engagement in social live streaming service. Specifically, this study explores the impact of social affordances on perceived flow, followed by user engagement including passive and active engagement. Empirical data analysis with 258 questionnaires suggests that social affordances affected users' flow perception, and flow has an effect on active as well as passive engagement. Contrary to the expectation in a hypothesized research model, only the impact of accessibility on flow was rejected.

Purpose - This study explores the causes behind the high rate of impulse purchases in live streaming e-commerce. Design/methodology/approach - The research model is empirically validated with survey data collected from 324 respondents in China, using the Partial Least Squares (PLS) methodology. Findings - We found that the interactivity and visibility of live streaming are key in creating para-social relationships and perceived presence, leading to customers' impulse purchases. Research implications or Originality - This study deepens the understanding of consumers' impulse purchases in live-streaming e-commerce, revealing that para-social relationships and perceived presence developed through real-time interactions can increase impulse buying. It also highlights the differences between relationship-oriented and task-oriented interactions in fostering customers' perceived presence and para-social relationships in live streaming.

This study aims at identifying any difference in the quality of life according to the patterns of living together in the family for the aged women who live in the rural areas. The findings of this study can be summarized in brief. First, those aged women who live alone showed a higher ratio of works like farming with less average income and less perception of living standards but better ADL than those of the aged women who live together with their family. Second, as a result of logistic regression analyses to identify factors to predict the patterns of living together in the family for the aged women in the rural areas, those aged women who live alone showed more cases of farming, higher ADL level, higher degree of economical preparations and more perception of intimacy with their offspring than those of aged women who live together with their family. Unlike these results, those aged women who live together with their family have less average income, more phone calls with their neighbor and higher quality of life that those of aged women who live alone. Third, as a result of impact variables in the quality of life by the pattern of living together in the family for the aged women in the rural areas, those aged women who live together their family showed higher quality of life with better preparations for the health, emotion and economy for their aged life, and with less number of offspring and more frequency of phone calls with their neighbor. In addition, those aged women who live along in the rural areas showed higher quality of life with better emotional preparations, better economic preparations, more number of offspring, more friendly with their neighbor and more emotional supports.

The aim of this paper is to simply present live load factor calculation methodology formulation with the addition of a simple new future load projection procedure to previously proposed two methods. For this purpose, Oregon Weigh-in-Motion (WIM) data were used to calculate live load factors by using WIM data. These factors were calculated with two different approaches and by presenting new simple modifications in these methods. A very simple future load projection method is presented in this paper. Using four different WIM sites with different average daily truck traffic (ADTT) volume, and all year data, live load factors were obtained. The live load factors, were proposed as a function of ADTT. ADTT values of these sites correspond to three different levels which are approximately ADTT= 5,000, ADTT = 1,500 and ADTT ≤ 500 cases. WIM data for a full year were used from each site in the calibration procedure. Load effects were projected into the future for the different span lengths considering five-year evaluation period and seventy-five-years design life. The live load factor for ADTT=5,000, AASHTO HS20 loading case and five-year evaluation period was obtained as 1.8. In the second approach, the methodology established in the Manual for Bridge Evaluation (MBE) was used to calibrate the live load factors. It was obtained that the calculated live load factors were smaller than those in the MBE specifications, and smaller than those used in the initial calibration which did not convert to the gross vehicle weight (GVW) into truck type 3S2 defined by AASHTO equivalents.

The recent surge in live streaming has also changed the market for classical performing arts. Now more than just recording live performances, content specific to live streaming platforms is being produced, and live streaming is emerging as a new alternative to promoting and enjoying classical performances. Therefore, this study empirically analyzed the effect of service quality factors of the classical live streaming performance on the viewer satisfaction and the purchase intention of the on-site performance over the data collected from 198 viewers. Results suggest that, among the service quality factors of the classic live streaming performance, video content, convenience, and price, except for real-time interaction, affected the viewer satisfaction, and viewer satisfaction in turn affected the purchase intention of the on-site performance. Thus the publicity effect of live streaming for classical performing arts seemed to be proved.

Long span bridges such as steel cable stayed and suspension bridges are usually more flexible than short to medium span bridges and expected to have large deformations. Deflections due to live load for long span bridges are important since it controls the overall heights of the bridge for securing the clearance under the bridge and serviceability for securing the comfort of passengers or pedestrians. In case of sea-crossing bridges, the clearance of bridges is determined considering the height of the ship master from the surface of the water, the trim of the ship, the psychological free space, the tide height, and live load deflection. In the design of bridges, live load deflection is limited to a certain value to minimize the vibrations. However, there are not much studies that consider the live load deflection and its effects for long span bridges. The purpose of this study is to investigate the suitability of live load deflection limit and its actual effects on serviceability of bridges for steel cable-stayed and suspension bridges. Analytical study is performed to calculate the natural frequencies and deflections by design live load. Results are compared with various design limits and related studies by Barker et al. (2011) and Saadeghvaziri et al. (2012). Two long span bridges are selected for the case study, Yi Sun-Sin grand bridge (suspension bridge, main span length = 1545 m) and Young-Hung grand bridge (cable stayed bridge, main span length = 240 m). Long-term measured deflection data by GNSS system are collected from Yi Sun-Sin grand bridge and compared with the theoretical values. Probability of exceedance against various deflection limits are calculated from probability distribution of 10-min maximum deflection. The results of the study on the limitation of live load deflection are expected to be useful reference for the design, the proper planning and deflection review of the long span bridges around the world.
