Background: The purpose of this study is to measure the Korean health literacy level and to analyse its gaps according to the factors of socioeconomic and health status and health behaviors. Based on this, policy implications were reviewed to improve the understandability on health information and to reduce the gap among socioeconomic groups. Methods: HLS-EU-Q47, a tool developed by the European Health Literacy Project, was used to conduct a face-to-face interview survey on the health literacy for the samples from general population. Results: The public general health literacy (HL) index was 34.5 out of 50. HL is consisted of three sub-dimensions: healthcare (HC-HL), disease prevention (DP-HL), and health promotion (HP-HL). And a HL analysis found scores of 34.7 points for HC-HL, 35.4 points for DP-HL, and 33.3 points for HP-HL. The level of all HL was different according to socioeconomic characteristics and health behavior. Conclusion: Based on the results of this study, more research activities on health-related literacy need to be conducted, and monitoring system on the HL level needs to be developed and implemented. In addition, a program to improve HL levels needs to be developed in order to strengthen the basis for a more sustainable healthcare system as an agenda with national health policy priority.

Objectives: Hyperlipidemia (HL) is a major cause of ischemic heart diseases. The size-limiting effect of ischemic preconditioning (IPC), a cardioprotective phenomenon, is reduced in HL, possibly because of the opening of the mitochondrial permeability transition pore (MPTP). The objective of this study is to see what effect pretreatment with Inula racemose Hook root extract (IrA) had on IPC-mediated cardioprotection on HL Wistar rat hearts. An isolated rat heart was mounted on the Langendorff heart array, and then ischemia reperfusion (I/R) and IPC cycles were performed. Atractyloside (Atr) is an MPTP opener. Methods: The animals were divided into ten groups, each consisting of six rats (n = 6), to investigate the modulation of I. racemosa Hook extract on cardioprotection by IPC in HL hearts: Sham control, I/R Control, IPC control, I/R + HL, I/R + IrA + HL, IPC + HL, IPC + NS + HL, IPC + IrA+ HL, IPC + Atr + oxidative stress, mitochondrial function, integrity, and hemodynamic parameters are evaluated for each group. Results: The present experimental data show that pretreatment with IrA reduced the LDH, CK-MB, size of myocardial infarction, content of cardiac collagen, and ventricular fibrillation in all groups of HL rat hearts. This pretreatment also reduced the oxidative stress and mitochondrial dysfunction. Inhibition of MPTP opening by Atr diminished the effect of IrA on IPC-mediated cardioprotection in HL rats. Conclusion: The study findings indicate that pretreatment with IrA e restores IPC-mediated cardioprotection in HL rats by inhibiting the MPTP opening.

We present here the effect of extracellular matrix (ECM) on the proliferation and physiology of HL-1 cardiac cells. HL-1 cell is from AT-1 mouse atrial cardiomyocyte tumor lineage. HL-1 cell can be serially passaged, yet they maintain the ability to contract which is a promising character of HL-1 cell for the cell based biosensors. HL-1 cells grow up on the ECM which can affect on the attachment and growth of HL-1. In this paper, we discuss HL-1 cell-ECM interactions with three different ECMs and non-treated surface. HL-1 cells are grown for 4 days after seeding then observed their attachment. Also they were immunostained by hoechst and EthD-1 for proliferation, phalloidin for Factin, and DAPI for nuclei. Fibronectin was revealed as the proper ECM material for HL-1 cell culture. This study can provide basic information for understanding the cell-ECM interactions and growth of HL-1 cells.

Purpose: The purpose of this study was to identify the level of health literacy (HL) and self-management adherence and to investigate the relationship between HL and self-management adherence in patients with chronic obstructive pulmonary disease (COPD). Methods: The participants of this study were 165 patients with COPD from a tertiary general hospital located in G city from February 10th to May 10th, 2021. The general HL was measured by the Korean health literacy assessment tool (KHLAT), COPD specific HL was measured by COPD-related HL tool, and COPD self-management adherence was measured by the COPD self-management tool. Results: The mean score of general HL was 60.45±9.42. The mean score of the COPD-related HL was 47.03±8.82. The mean score of the COPD self-management adherence was 87.58±14.47. There were significant differences in the level of COPD-related HL according to age (t=2.43, p=.016), and in the level of general HL (F=10.96, p<.001) and the level of COPD-related HL according to the level of education (F=19.14, p<.001). There were significant correlations between the level of general HL and the level of COPD-related HL (r=.75, p<.001) and the level of COPD-related HL and the level of self-management adherence (r=.219, p=.005). Conclusion: The HL of COPD patients was at the level of mild school 1-2 years in this study. Therefore, nurses who care for COPD patients should understand patients' level of HL and communicate self-management skills with patients at a level appropriate for patients' HL. In addition, it is necessary to develop strategies to easily learn COPD-related information when providing self management skills or training.

개인 휴대단말기로부터 측정된 생체정보 데이터가 PHR에 데이터베이스화되기 위해서는 응용 계층 표준 프로토콜인 HL7 CDA 표준에 따라야 한다. 하지만 국제 표준 HL7 CDA는 병원 시스템 간 의료정보 전달을 위한 프로토콜이기 때문에 개인 건강 기기로부터 측정된 생체 정보가 IEEE 11073 PHD 표준에 준하여 전달하더라도 HL7 CDA 프로토콜과 연동될 수 없다. 즉, 모바일 단말기 기반의 u-헬스케어 모니터링 서비스를 위해서는 IEEE 11073 PHD와 HL7 CDA 간 메시지 변환 게이트웨이가 필요하다. 이에 본 논문에서는 개인 휴대단말기를 통해 원격지에 있는 의료진이 사용자의 생체데이터를 실시간 관리하기 위해 ISO/IEEE 11073과 HL7 CDA 간 메시지 변환 게이트웨이 및 HL7 기반 진단지원시스템을 설계하였다.

With the rapid advance of information technology and the popularity of digital medical, medical information are growing, the process of hospital digitalization are gradually quicken and systems involved are more and more. HIS system mainly deals with patient information, it follows the standard of HL7. While PACS system mainly manages image information, it follows the standard of DICOM. Because HIS and PACS deal with different information and follow different standards, it is difficult to directly communicate. This paper presents a method of establishing HL7/DICOM gateway to realize the information exchange of HIS and PACS. The HL7/DICOM gateway designed in this paper is made up of three modules. First, HL7 messages and triggered events are designed to achieve the function of transaction processing module. According to the designed HL7 messages, four message interface functions are defined to accomplish the function of send/receive messages module. Finally, the algorithm of construct/parse messages is given to complete the function of construct/parse messages module. Result shows that HIS and PACS realize information exchange successfully by using the HL7/DICOM gateway Implemented in this paper.

The LEX system is a XML-based framework for medical information consolidation. The Lex makes it possible for heterogeneous HISs(Hospital Information Systems) exchange and share HL7 messages by storing the messages into a single Central Clinical Database. In this paper, we propose a HL7 message server independently interoperable from existing HIS to generate HL7 messages, and design an XML database schema suitable for storing and manipulating such data. We also propose a new DTD for efficient transformation of HL7 messages to XML documents for storage saving as well as supporting patient-oriented information retrieval.

To reveal effects of gamma-irradiation with various doses on the expressions of C4H and F5H genes, the transcription levels of OsC4HL and OsF5HL were investigated in leaves and stems of two rice cultivars, Ilpoombyeo and IR-29, after the irradiation with 5, 10, 50, or 100 Gy for 4 h. In overall pattern of 24 h after the irradiation, the transcription levels of the two genes increased with the increasing doses of radiation in the leaves of both cultivars, except that of OsC4HL in IR-29. However, in the stems, the transcription level of OsF5HL increased in Ilpoombyeo and decreased in IR-29 dose-dependently, while that of OsC4HL decreased in Ilpoombyeo with the increasing doses of radiation and remained constant in IR-29. When the expressions of OsC4HL and OsF5HL were investigated in a time-course after the irradiation with 100 Gy, they reached their highest levels in the leaves of both cultivars 5 hand 72 h after the irradiation, respectively. Therefore, we suggest that the expressions of OsC4HL and OsF5HL, which involved in the same phenylpropanoid pathway, are differentially regulated during the post-irradiation period, showing different cultivar and tissue specificity. Furthermore, the dose dependency of the gene expressions is also discussed immediately after the irradiation.
