The present study examined pharmacokinetic profiles of KBP31705-Cl27 and KBP30603-901, new platinum coordination complexes synthesized as anticancer candidates, in comparison with two well-known platinum-containing anticancer agents, cisplatin and carboplatin in rats. Under sodium pentobarbital anesthesia of male Sprague-Dawley rats, urinary bladder, and femoral artery and vein were catheterized for urine collection, blood sampling and drug injection, respectively Following i.v. administration of cisplatin (2 mg/kg), KBP31705-C127 (2 mg/kg), carboplatin (20 mg/kg) or KBP30603-901 (20 mg/kg), blood samples were collected at 2, 4, 6, 8, 10, 15, 20, 30, 45, 60 and 120 minutes. Urine samples were collected at 1-hr interval for 4 hr. Platinum concentrations in plasma and urine were measured using an inductively coupled plasmamass spectrometer. The plasma concentration-time curves were biphasic for all drugs during the time period studied. Compared with cisplatin, KBP31705-C127 showed similar decay patters in the alpha- and betaphases with slightly lower plasma concentrations. Urinary platinum excretion for cisplatin and KBP31705-C 127 was 56 and 52% of the administered dose in 4 hr, respectively. With regard to carboplatin and KBP 30603-901, a similar decay pattern was also observed in the alpha-phase. The half life of KBP30603-901 in the beta-phase, however, was much longer than that of carboplatin, which was consistent with the urinary excretion results that 46 and 59% of the administered dose were excreted in the urine in 4hr, respectively. The results suggest that platinum coordination complexes are primarily excreted via the renal route and KBP30603-901 can elicit longer duration of action due to slower renal excretion compared to carboplatin.

This paper represents a reentry time prediction analysis of CZ-5B rocket-body in China, subject to analysis of the Inter-Agency Space Debris Coordination Committee Reentry (IADC) reentry test campaign conducted in May 2021. Predicting the reentry of space objects is difficult to accurately predict due to the lack of accurate physical information about target, and uncertainty in atmospheric density. Therefore, IADC conducts annual re-entry campaigns to verify analysis techniques by each agency, and the Korea Aerospace Research Institute has also participated in them since 2015. Ballistic coefficient estimation method proposed to predict target reentry time and the result confirmed the difference of 73 seconds, which confirms the accuracy of the proposed method.

In this paper a novel medium access control mechanism is investigated as a means to support real-time services. The primary goal is to provide constant-bit-rate voice call services to pairs of autonomous mobile nodes operating in ad hoc networks. Here, a time-slot reservation based MAC is considered to provide real-time voice calls and a new MAC called the time-slot reservation coordination function(TRCF) is presented. In addition to this isochronous type MAC protocol development, the proposed protocol is modeled using a Markov chain in order to predict its behavior. The performance of TRCF is analytically derived and the performance measures such as average wait time taken for a call connection and throughput are obtained.

웹 서비스는 서비스 가용성(availability)과 성능(performance)연에서 신뢰성을 항상 보장해 주지 못한다. 동적 서비스 조정(Dynamic Service Coordination)은 웹 서비스를 호출하는 시스템이나 응용 프로그램 내에서의 비 신뢰적인 문제상황을 처리하는 기술이다. 이 환경 내에서의 웹 서비스는 제한된 시간내에 응답 하지 못하는 등의 문제가 발생 할 경우, 신뢰적인 웹 서비스의 호출을 위해 다른 웹 서비스로의 대체작업이 런타임(run-time)에 이뤄진다. 본 논문에서는 웹 서비스를 위한 동적 서비스 조정 프레임워크를 제안한다. 프레임워크 내에서 동적 서비스 조정의 지원 및 웹 서비스 호출을 담당하는 클래스와 워크플로우가 생성되고, 생성된 클래스 메소드를 호출함으로써 신뢰적인 웹 서비스 호출이 가능하다. 호출작업이 간접적으로 이뤄짐으로 인해 어느 정도의 성능적 손실이 발생하나, 이 방식을 통해 얻는 시스템 유연성과 신뢰성의 측면을 고려한다면, 충분히 감 수 될 수 있다.

In this paper, we analyze the effect of the data aggregation level on the MAC performance when RFID (Radio Frequency Identification) logistics data, which can be aggregated at RFID readers to reduce the transmission overhead, are transmitted in IEEE 802.11 wireless LANs. For various data aggregation levels, the throughputs and latencies of the DCF (Distributed Coordination Function) and PCF (Point Coordination Function) MAC protocols are analyzed by computer simulation. From the simulation analysis, we propose the appropriate input traffic load for real-time RFID logistics data transmitted in IEEE 802.11 wireless LANs.

Management of today's dynamic projects requires a shift of focus from product to process. The purpose of traditional project controls is to conform performance to plan. The purpose of lean project controls is to make the best possible choices at each point in time during the course of the project, as well as contributing knowledge to the parent organizations so they can learn from project experience. The Lean Construction Institute(LCI) proposed the Last Planner System(LPS) capable of accomplishing that purpose, principally through controlling the quality of planning and of management processes themselves, as distinct from concentrating exclusively on project performance. The case project was a pilot project for the implementation of the Last Planner. Consequently, the coordination of the work on this project was extremely successful. The project had its share of challenges. The coordination did not prevent design problems, or supplier errors, but helped the team deal with the problems effectively while maintaining the work flow. The last planner helped the contractors know: a) who will be doing what and where, b) what each one needs from the others, and c) what are the project priorities. The system itself created a more collaborative environment, because it 'demands' that the subcontractors address these issues.

The DCF (Dcistributed Coordination Function) and PCF (Point Coordination Function) are the basic MAC (Medium Access Control) protocols of IEEE 802.11 wireless LANs. According to the DCF, each node performs the exponential backoff algorithm before the transmission of its data frame. Each node doubles the backoff waiting time before the transmission of its data frame whenever it detects the transmission collision with other nodes. Therefore, as the number of the active nodes having the data frames to transmit increases, the overall MAC performance of the DCF decreases. On the other hand, according to the PCF, each node is granted the transmission opportunity by which the PCF transmission is possible without the collision with other nodes. Therefore, as the number of the active nodes increases, the MAC performance of the PCF increases, In this paper, considering the tradeoff of MAC performance between the DCF and PCF, a hybrid MAC protocol is proposed to enhance the performance of IEEE 802.11 wireless LANs.
