Objective: The aim of this study was to establish the developmental history of hospice palliative care (HPC) with Korean medicine (KM). Methods: We compared the developmental history of HPC in Korea with that of Britain, the United States, Taiwan, Japan, and China. The articles in English or Korean published until Feb. 2017 were searched using 'Hospice' or 'Palliative care' with the name of each nation in the PubMed, MEDLINE, ScienceDirect, and CINAHL (Cumulative Index to Nursing and Allied Health Literature) databases for foreign articles and OASIS (Oriental Medicine Advanced Searching Integrated System) for domestic articles. Books and gray literature were searched on the same databases and websites of the Ministry of Health and Welfare and related organizations in each country. Results: Modern palliative care began with the hospice movement led by Dr. Cicely Saunders. HPC in Korea started earlier than in other countries but it took considerable time for social consensus, so Korean policies have only been published recently. In this process, KM was excluded from HPC. For this reason, western medicine in Korea does not fully accept the spirit of HPC, the government does not take an aggressive stance with KM, and the institutes of KM do not have any interest in HPC. The World Health Organization recommends the establishment of policies and programs connected with a country's own health care system. In 2015, the Korean government made the third comprehensive plan for the development of KM. It included critical pathway guidelines about cancer-related fatigue and anorexia. More effort is required to set up HPC than other care types because Korea has two medical systems. Conclusions: Each nation has been trying to improve systems of HPC. We need to overcome the problems and bring out the best by making our own model of HPC with KM.

Because of the shortage of construction workers due to The rising labor costs and an aging labor force, construction time has been extended. As a solution, The construction time of high-rise buildings can be reduced by adopting precast concrete construction methods. Most relevant studies have focused on the development and structural analysis of such methods and not on their construction management. Therefore, this study focused on the construction management of the hollow precast concrete column (HPC) method. The objective of this study was to evaluate the performance of HPC formulations through the analytic hierarchy process and benefit-cost analysis. After a gap analysis of the available literature and expert interviews, the evaluation criteria were selected. A questionnaire survey was administered to professionals with ample experience in precast concrete construction for the pair-wise evaluation of the benefit and costs of the HPC method. The results show that the benefits of the HPC method outweighed its costs. Therefore, the HPC method is a suitable substitute for the half-slab method.

A new hydroxypropylcellulose (HPC) capable of exhibiting reflection colours in the temperature ranges of about 60-$130^{\circ}C$ and acrylic acid esters of HPC (ESs) with degree of esterification (DE) ranging from 1 to 3 were synthesized. The crosslinked ES films with the optical pitch ($\lambda_m$) ranging throughout the visible region were also prepared by exposing thermotropic cholesteric phases of ESs with a DE of more than 2 to UV light at $50^{\circ}C$. The thermal and optical properties for both the uncrosslinked and crosslinked samples and the swelling behavior of the crosslinked films in acetone were investigated. The $\lambda_m$'s of ESs, as well as HPC itself, increased with temperature. However, the $\lambda_m$'s of ESs were larger than of HPC at the same temperature and decreased with increasing DE. The temperature dependence of $\lambda_m$of the crosslinked samples was much weaker than that of ESs. Moreover, in contrast with ESs that exhibit a decrease of the isotropization temperature with increase in the DE, the networks were found to decompose at about $210^{\circ}C$, giving no transition to an isotropic state. The crosslinked samples exhibited an anisotropic swelling, suggesting that the two-dimensional crosslinking preferentially performs between ES molecules.

This study aims to develop a cost-based high-performance concrete (HPC) mix optimization system based on an integrated approach using artificial neural networks (ANNs) and genetic algorithms (GA). ANNs are used to predict the three main properties of HPC, namely workability, strength and durability, which are used to evaluate fitness and constraint violations in the GA process. Multilayer back-propagation neural networks are trained using the results obtained from experiments and previous research. The correlation between concrete components and its properties is established. GA is employed to arrive at an optimal mix proportion of HPC by minimizing its total cost. A system prototype, called High Performance Concrete Mix-Design System using Genetic Algorithm and Neural Networks (HPCGANN), was developed in MATLAB. The architecture of the proposed system consists of three main parts: 1) User interface; 2) ANNs prediction models software; and 3) GA engine software. The validation of the proposed system is carried out by comparing the results obtained from the system with the trial batches. The results indicate that the proposed system can be used to enable the design of HPC mix which corresponds to its required performance. Furthermore, the proposed system takes into account the influence of the fluctuating unit price of materials in order to achieve the lowest cost of concrete, which cannot be easily obtained by traditional methods or trial-and-error techniques.

최근 방송 통신 기술의 눈부신 발전에 힘입어 등장한 데이터 방송(Data Broadcasting)은 시청자에게 영상과 음성환 아니라 기존에는 접할 수 없었던 다양한 서비스들을 제공하고 있다. 이런 데이터 방송을 수신하기 위해서는 TS로부터 데이터를 추출하고 처리할 수 있는 미들웨어(middleware)가 포함된 셋탑박스(set-top box)가 필요하다. 그리하여 MHP, OCAP, ACAP 등 여러 데이터 방송 시스템의 미들웨어 표준 규격이 정의되었다. 그 중 MHP의 경우, OpenMHP라는 오픈 소스 프로젝트를 통해 PC 상에서 간단하게나마 MHP API를 테스트 해 볼 수 있는 환경을 제공해 주고 있다.[1] 하지만 셋탑박스 내에서 하드웨어를 이용하는 작업들은 거의 구현되지 못 했기 때문에 테스트에 있어 극히 제한적일 수밖에 없었다. 따라서 본 논문에서는 소프트웨어적으로 셋탑박스 환경을 에뮬레이션 해주는 Virtual Set-Top Box(VSTB)를 설계, 구현하였다. 셋탑박스가 없는 환경이나 간단한 시뮬레이션이 필요한 경우, 실시간 스트림 역다중화와, 파싱, 필터링 작업등이 지원되는 가상 셋탑박스 시스템을 통해 MHP 미들웨어 API를 테스트하는데 유용한 역할을 할 수 있을 것이다.

The concept of modern medical science has been changing from the old period which is simple treatment of diseases to the new period which is active prevention from diseases. Because preventing diseases is more effective and economical than treating diseases. This is the reason that needs to HPC at the concept of Health diagnosis. Another reason of HPC is to diagnose the stresses and to prescribe an effective exercise and to show the way of nutrition intake in order to keep up the condition of individual health. According to these reasons, I foresee the demand of remodelling HPC from existing HEC on this study. I define the common space that HEC uses duplication with HPC. I also aim to analyze them and to examine the alterable function and proper size of common space in case of remodelling.

With the progress of NGS technologies, large genome data have been exploded recently. To analyze such data effectively, the assistance of HPC technique is necessary. In this paper, we organized a genome analysis pipeline to call SNP from NGS data. To organize the pipeline efficiently under HPC environment, we analyzed the CPU utilization pattern of each pipeline steps. We found that sequence alignment is computing centric and suitable for parallelization. We also analyzed the performance of parallel open source alignment tools and found that alignment method utilizing many-core processor can improve the performance of genome analysis pipeline.

High performance concrete (HPC) has been extensively used in thin overlay for repair purpose due to its excellent strength and durability. This paper presents an experiment, where the sensor-instrumented HPC overlays have been followed by dynamic strain and moisture content monitoring for 1 year, under normal traffic. The vibrating wire and soil moisture sensors were embedded in overlay before construction. Four given HPC mixes (2 original mixes and their shrinkage-modified mixes) were used for overlays to contrast the strain and moisture results. A calibration method to accurately measure the moisture content for a given concrete mixture using soil moisture sensor was established. The monitoring results indicated that the modified mixes performed much better than the original mixes in shrinkage cracking control. Weather condition and concrete maturity at early age greatly affected the strain in concrete. The strain in HPC overlay was primarily in longitudinal direction, leading to transverse cracks. Additionally, the most moisture loss in concrete occurred at early age. Its rate was very dependent on weather. After one year, cracking survey was carried out by vision to verify the strain direction and no cracks observed in shrinkage modified mixes.
