In this paper, a novel method called location-based delivery (LBD), which combines the short message service (SMS) and global position system (GPS), is proposed, and further, a realistic system for tracking a target's movement is developed. LBD reduces the number of short message transmissions while maintaining the location tracking accuracy within the acceptable range. The proposed approach, LBD, consists of three primary features: Short message format, location prediction, and dynamic threshold. The defined short message format is proprietary. Location prediction is performed by using the current location, moving speed, and bearing of the target to predict its next location. When the distance between the predicted location and the actual location exceeds a certain threshold, the target transmits a short message to the tracker to update its current location. The threshold is dynamically adjusted to maintain the location tracking accuracy and the number of short messages on the basis of the moving speed of the target. The experimental results show that LBD, indeed, outperforms other methods because it satisfactorily maintains the location tracking accuracy with relatively fewer messages.

Purpose: The purpose of this study was to investigate the effect of a short message service intervention on adherence to maximal barrier precautions (MBP) and catheter-related blood stream infections. Method: The data were collected from March to September, 2008, at an 826-bed university-affiliated hospital in Daejeon. The study participants were 24 physicians who were inserting central catheters and 133 patients (control group 78 and intervention group 55) with central catheter insertions. The researcher sent the message (adherence to MBP and optimal recommendations) to each internal medicine doctor using the short message service (SMS) for cellular phones. Messages were sent monthly for 3 months. Data were analyzed by chi-square test and t-test using SPSS 12.0 windows program. Result: Adherence to maximal barrier precautions was significantly increased from 44.9% to 69.1% (p=.006) after the SMS intervention. But changes in the rate of CRBSI (catheter related blood stream infection) between the intervention group (1.89) and the control group (4.45) were not significant (p=.323). Conclusions: The results indicate that the SMS intervention is effective in increasing the adherence to maximal barrier precautions and the SMS intervention can be recommended for utilization in infection control nursing practice.

Both message appeals and individual characteristics can influence the effectiveness of sustainable product promotions. Applying the agency-communion orientation to the advertising message research context, this study examined the interplay between message appeals and agency-communication orientations in impacting purchase intentions. The findings from a 2 (message appeal: self-interest vs. public-interest message) × 2 (motivational orientation: agency vs. communion) experiment revealed a communion-over-agency effect on consumer purchasing decisions for public-interest message appeals. In the self-interest message condition, we found no statistically significant difference in impact between agency and communion on purchase intentions. In short, we contribute to advertising effectiveness research by showing that agency-communion orientations moderate the effect of message appeals. We also explain the practical implications of these findings for effective sustainable communication in advertisements based on individuals' motivational orientations.

In this research, we analyze the effects of price discounts and scarcity message (both quantity limitation message and time limitation message) on the purchase intention in the smart-phone environment. The purchase intention becomes higher at high discount rate and with scarcity message (both quantity limitation message and time limitation message). We also analyze the moderating effects of consumer's shopping value and distance between the consumer and the store on the effects of price discounts and scarcity message (both quantity limitation message and time limitation message) on the purchase intention. On average, the effects of price discount, time limitation message and quantity limitation message on the purchase intention become the highest levels for consumers pursuing hedonic shopping value. The effects of price discount, time limitation message and quantity limitation message on the purchase intention become higher when they are offered within a short distance between the coupon provider and the target customer.

최근 폭발적인 인기를 끌고있는 짧은 동영상 애플리케이션(e.g., TikTok, YouTube Shorts)은 광고집행을 위한 새로운 SNS 플랫폼으로 관심을 받고 있다. 이러한 배경에서 본 연구는 짧은 동영상 애플리케이션에서 집행되고 있는 스토리텔링 광고를 분류하고 그 효과를 측정하는 것을 목적으로 한다. 상술 하면, 전통적 광고 분류기준인 허구성을 기준으로 스토리텔링 광고를 리얼리티, 패러디, 창의형식으로 구분하였다. 또한 인지심리학 정보처리 맥락에서 높은 수준과 낮은 수준의 메시지가치가(MSV)로 광고들을 분류하였다. 전 세계적으로 가장 많은 이용자를 보유한 틱톡을 대상으로 총 784명 중국인 이용자의 응답을 수집하였다. 연구결과 두 개의 주요 변인(허구성과 MSV) 간에 유의미한 조절효과가 발생하였다. 가장 주목할 만한 결과는 정보처리 리소스의 사용을 높게 요구하는 높은 허구성의 창의적 기법이 높은 메시지자극가를 사용하게 되면 인지과부하(cognitive overload)를 야기하여 광고효과가 낮아지는 것으로 나타났다. 보다 자세한 이론적 논의와 효과적인 짧은 동영상 스토리텔링 광고제작을 위한 제언들을 본문에서 상세히 소개하였다.

본 논문에서는 CDMA무선망을 이용한 PDA기반의 취약한 전송로 상에서도 안전하게 메시지를 전송할 수 있는 서비스 모델과 PDA 특성을 고려한 보안 메시지 전송 프로토콜 제안하고 구현하였다. 제안된 서비스는 유선 인터넷 망과 오프라인 상태의 클라이언트 단말기를 SMS(Short Message Service)를 이용하여 연결하였다. 단말기는 SMS 메시지 수신 후에 SMS의 데이터를 분석하여 RAS(Remote Access Service)를 통해 데이터 채널을 생성하고 서버 측의 데이터가 PUSH 되도록 구현되었다. 구현된 보안 프로토콜은 SMS와 데이터 채널을 가지는 2채널 방식을 이용하여 각 통신 부문에서 안전한 통신을 보장 할 뿐 아니라, 안전한 세션키 통신을 위한 비표(nonce table)키 방식을 사용하였기 때문에 세션키 전송 시 키 길이도 줄이면서 높은 비트의 암호화를 할 수 있는 효과를 보였다.

Idle listening is very critical source of energy dissipation in wireless sensor networks. To reduce idle listening, we propose preamble sampling MAC that is named EESP-MAC. The main idea of EESP-MAC is to add control information into the short preamble frame. So the stream of short preambles is used not only for preamble sampling but also for avoiding overhearing, decreasing control packet overhead and reducing the listening of the redundant message, caused by message-flooding.

Purpose: This study was conducted to investigate the effects of preparatory nursing information and information offering by SMS on anxiety and nursing satisfaction among family members of ICU (Intensive Care Unit) inpatients. It utilized a quasi-experimental research design with a non-equivalent and non-synchronized control group. Methods: The experimental group and the control group were offered a booklet guiding ICU and were offered face-to-face information by nurses using Power Point. The experimental group was additionally offered SMS (short message service) message on patient's safety at night every morning during the hospital stay between 8 and 9 am. All participants in the experimental group and the control group were measured in reference to anxiety at the point of hospitalization and were surveyed anxiety and nursing satisfaction on the third day of hospital stay. Results: The anxiety demonstrated no significant difference between the groups, while the nursing satisfaction was significantly higher in the experimental group than that of the control group. Conclusion: Proving direct information and indirect information via SMS message were considered effective in improving the family member's satisfaction with nursing care. The frequencies of SMS message and the contents of the message and information need to be defined and specified in the given population.
