Background: Our objective was to determine the knowledge and attitudes of Thai generalists (general physicians) toward palliative terminal cancer care (PC) in a primary care setting. Materials and Methods: We performed a cross-sectional descriptive survey using a self-administered questionnaire. The total number of completed and returned questionnaires was 63, giving a 56% response rate. Data analysis was based on these (Cronbach's alpha=0.82) and percentages and mean values were assessed using the Fisher's exact test to determine the correlation of variables. Results: Overall, attitude and knowledge levels were slightly satisfactory. Results indicated that general physicians had moderate scores in both attitudes (84.1%) and knowledge (55.7%) regarding palliative terminal cancer care. However, they had insufficient knowledge regarding truth telling, pain control and management with morphine, emergency management in terminal cancer care and treatment of fluid intake in terminal stages. Attitude and knowledge scores were statistically correlated (p=0.036). Knowledge scores were further positively associated with being taught palliative care in their medical curriculum (p=0.042). Conclusions: Formal education in palliative care and development of palliative care services are very much needed in Thailand to provide holistic care to terminally ill patients.

The general situation of system composition and safety management of high-speed railway terminal is investigated and a comprehensive evaluation index system of operational security is established on the basis of railway laws and regulations and previous research results to evaluate the operational security management of the high-speed railway terminal objectively and scientifically. Index weight is determined by introducing interval eigenvalue method (IEM), which aims to reduce the dependence of judgment matrix on consistency test and improve judgment accuracy. Operational security status of a high-speed railway terminal in northwest China is analyzed using the traditional model of fuzzy comprehensive evaluation, and a general technique idea and references for the operational security evaluation of the high-speed railway terminal are provided. IEM is introduced to determine the weight of each index, overcomes shortcomings of traditional analytic hierarchy process (AHP) method, and improves the accuracy and scientificity of the comprehensive evaluation. Risk factors, such as terrorist attacks, bad weather, and building fires, are intentionally avoided in the selection of evaluation indicators due to the complexity of risk factors in the operation of high-speed railway passenger stations and limitation of the length of the paper. However, such risk factors should be considered in the follow-up studies.

This study is to find subjects for the Automated Container Terminal(ACT) development and container terminal system. Also we analyze the present condition of the container terminal system in Pusan port and its automation level by systems approach. And this paper aims at evaluating on the priority of R&D investment until the beginning of the second stage of New Pusan Port Project(2006). In this process we have considered 8 evaluation indexes(cost, labor, area, time, volume, reliability. safety, convenience) to analyze 6 subsystems. The priority of R&D until target year by sub-systems is as follow: 1. Cargo Handing System, 2. Transfer System, 3. Port Entry System, 4. Storage System (Distribution & Manufacturing System included), 5.Inland Transport System, 6.Port Management & Information System.

부산항 'A' 터미널에서 발생한 지난 3년간의 사고 데이터를 분석하여 어떤 장비가 가장 많이 사고를 발생하였고 어떤 위험점이 가장 높은지를 위험성 평가기법으로 알아보고, 이러한 사고를 미연에 방지하기 위한 방안을 보우타이 기법을 활용하여 제시하고자 한다. 실증자료를 분석한 결과 터미널 내의 이동장비 중 야드 트랙터의 충돌사고가 가장 높은 것으로 나타났다. 안전한 부산항을 만들기 위하여 우리는 가장 먼저 야드 트랙터의 충돌사고 예방법 (Control measure)과 사고 발생 시 대처방안 (Recovery measure)을 철저히 준비하여 사고를 미연에 방지하여야 할 것이다. 본 연구의 결과는 관련 실무에 다양한 시사점을 제공하였다.

SCADA(Supervisory Control and Data Acquisition) 시스템은 국가의 중요한 기반 망인 전력, 가스, 상하수도 등을 제어하기 위해 사용된다. 이전의 폐쇄적인 통신 환경과 달리 최근 개방 통신 환경을 사용함에 따라 안전한 통신을 위한 키 관리 기술이 연구되고 있다. 본 논문에서는 SCADA 시스템을 구성하는 MTU(Master Terminal Unit), Sub-MTU, RTU(Remote Terminal Unit)에 각각 페어링을 이용한 ID 기반의 키 관리 방안을 제시한다. 또한, 예상치 못한 사고나 악의적인 공격들로 인하여 장치들의 개인 키가 노출되거나 또는 KMS(Key Management System)의 마스터 키가 노출되었을 경우에도 SCADA의 키 관리 시스템을 복구할 수 있는 방법을 제시한다.

선사가 기항노선의 주요 선정요인으로 컨테이너터미널 하역비를 들 수 있으므로, 하역비의 원가를 산정하는 것은 매우 중요하지만 컨테이너터미널을 대상으로 한 활동기준원가분석의 연구는 미미한 실정이다. 본 연구는 시간을 고려하여 개선된 시간-동인활동기준원가계산을 바탕으로 컨테이너터미널에서 적용 가능한 Conceptual Framework과 원가관리모델을 제시한다.

As the performance of the mobile terminal becomes higher, the power consumption gradually increases. As a result, power management is one of the most important issues in mobile system with battery. In this paper, we describe an DPM(Dynamic Power Management) using DVS(Dynamic Power Management) as a power management mechanism in Qplus operating system. DVS generally considers a specific device such as CPU, whereas we consider the relations with other hardware components as well as each component. We specially focus on the relation between CPU, memory and LCD devices. We also designs a kernel monitor to collect information to decide the policy for power management. According to the experimental results, the proposed method enables to save much power.

SCADA (Supervisory Control and Data Acquisition) systems for remote monitoring, data acquisition and control are applied to major industrial infrastructures including power, water and railroad. Recently, there are many researches on key management scheme for secure communication due to change to the open network environment. These systems are located at far distances and are connected to the main control center through various types of communication methods. Due to the nature of these systems, they are becoming the significant targets of cyber attack. We propose an efficient key management scheme which is established on ID-based cryptosystem without an expensive computation on MTU (Master Terminal Unit), Sub-MTU, and RTU (Remote Terminal Unit). The proposed method is secure and effective in key management among multiple legitimate devices.
