In this study, data from the 11th year of the Korean Welfare Panel Study (2016), the 12th year (2017), the 13th year (2018), and the 14th year (2019) were used to verify whether drinking problems in adults had an end-to-end effect on depression. The analysis showed that, first, the initial value of depression has a static (+) relationship with the initial value of problem drinking, and a significant relationship with the rate of change in problem drinking. Second, the supply and demand households showed a static relationship with the initial value of depression, the initial value of problem drinking. Third, in the case of people with disabilities, the relationship between the initial value of depression, the initial value of problem drinking, and the amulet (-). Therefore, it was suggested that the development of drinking problem prevention programs and education should be actively carried out in school education before adulthood.

Background: Intravenous fluid therapy is one of the most common interventions in critically ill patients. Normal saline is frequently used, but there have been some concerns about hyperchloremia. Due to closer to plasma composition, crystalloids have been used as alternatives to normal saline. However, the optimal choice of resuscitative fluids remains controversial. Methods: MEDLINE, EMBASE, and CENTRAL were comprehensively searched until July 2021 to compare balanced crystalloids with normal saline in critically ill patients with the risk factors for multiple organ dysfunction syndromes (MODS).The primary endpoint was composite mortality. Secondary outcomes were acute kidney injury (AKI)/acute renal failure (ARF), and new receipt of renal replacement therapy (RRT). Results: A total of 1,240 studies were searched, and finally, 8 randomized controlled trials and 5 cohort studies were included. In the meta-analysis of composite mortality of 30,710 patients, balanced crystalloids compared to normal saline were significantly associated with reduced mortality (OR 0.80, 95% CI 0.68-0.95). In AKI/ARF, balanced crystalloids had a lower risk than normal saline (OR 0.91, 95% CI 0.84-0.99). There was no difference between balanced crystalloids and normal saline in risk of new receipt of RRT (OR 0.91, 95% CI 0.80-1.04). Conclusion: In fluid resuscitation for patients at high risk of MODS, the use of balanced crystalloids showed a significantly lower incidence of mortality compared to normal saline.

Phishing is a form of online identity theft that aims to steal sensitive information such as online banking passwords and credit card information from users. Phishing scams have been receiving extensive press coverage because such attacks have been escalating in number and sophistication. According to a study by Gartner, Many Internet users have identified the receipt of e-mail linked to phishing scams and about 2 million of them are estimated to have been tricked into giving away sensitive information. This paper presents a novel browser extension, AntiPhish, that aims to protect users against spoofed web site-based phishing attack.

In performance-based on fire safety design of buildings, design fires are assumed to be relatively coarse information on potential combustible objects described by its name, weight, size and main constituent materials. As early as 1970s, researchers from Japan has employed various methods of research regarding combustibles investigations. In result, researchers came up with one method that is being presently used. Therefore, our country basis in collection of data for combustibles yielded average measure, receipt rate of furniture usage and execution of combustible investigations to occupancy zone of university respondents. We have found out problem about excessive usage of multi-outlet extensions through research.

The rapid increase in apartments of Korea brought about overall changes in the life style, and definitely played the biggest role to convert into western style. Since 1960, furniture has been changed for 50 years along with apartments, but furniture companies and the academic world had insufficient historical materials and lack of study. In addition, considering the changing trend according to residents' life style, the data of furniture industries should be collected to study every year or in 5 years at least. Therefore, this study aims to provide basic data that gives historical materials or design clues based on recent AV equipment-oriented storage furniture in the living room that prioritized design in public space. Accordingly, the study looked into the periodical trends of Korean furniture industries, analyzed 10 furniture companies in Korea which is actively doing business as the sample and arranged key points of periodical changes of furniture in the table, and suggested the conclusion according to the image map, style, color, material, and function.

The sensor network is a key component of the ubiquitous computing system which is expected to be widely utilized in logistics control, environment/disaster control, medical/health-care services, digital home and other applications. Nodes in the sensor network are small-sized and exposed to adverse environments. They are demanded to perform their missions with very limited power supply only. Also the sensor network is composed of much more nodes than the wireless ad hoc networks are. In case that some nodes consume up their power capacity, the network topology should change, and rerouting/retransmission is necessitated. Communication protocols studied for conventional wireless networks or ad hoc networks are not suited for the sensor network resultantly. Schemes should be devised to control the efficient usage of node power in the sensor network. This paper proposes a medium access protocol to enhance the efficiency of energy consumption in the sensor network node. Its performance is analyzed by simulation.

The purpose of this study is to examine the legal aspects on the formation of international contract in electronic commerce. The findings could be summarized as follows. rug, the contract doctrine of the contract formation by electronic data message, time of dispatch and receipt of data message, error in electronic communication, contract form and electronic signature could be supported or protected by the existing contract doctrine. Second, In relation to the contract formation arranged by electronic agents, the established contract doctrine provides no clear answer to the question whether changes provided by the interaction of electronic agents are enforceable. The enforceability question is left to future legislation. Finally, It is necessary that a significant level of formality together with the disclosure on the contract formality by certain act be conveyed 10 a potential buyer so that the buyer is impressed that the contact by the certain act could be valid.

In this paper, we investigated the throughput of a cognitive radio network where two primary frequency channels (PCs) are sensed and opportunistically accessed by N secondary users. The sharing sensing member (SSM) protocol is introduced to sense both PCs simultaneously. According to the SSM protocol, N SUs (Secondary User) are divided into two groups, which allows for the simultaneous sensing of two PCs. With a frame structure, after determining whether the PCs are idle or active during a sensing slot, the SUs may use the remaining time to transmit their own data. The throughput of the network is formulated as a convex optimization problem. We then evaluated an iterative algorithm to allocate the optimal sensing time, fusion rule and the number of members in each group. The computer simulation and numerical results show that the proposed optimal allocation improves the throughput of the SU under a misdetection constraint to protect the PCs. If not, its initial date of receipt shall be nullified.
