이 문서는 근래에 새로이 표준화된 PMI 와 관련한 몇 가지 용어와 개념에 관해 간략히 정리하고 설명할 것을 목적으로 한다. PKI는 강력한 보안 기반으로써 가능하지만 시스템 통합의 입장에선 그리 큰 매력을 가지지 못하낟. 공개키 확인서라는 것은 소유자만을 전제한 것이고, 모든 기능이 소유자의 식별(인증)에서부터 시작한다.(중략)

국내 건설산업에 있어서 기술과 정보의 기반구조를 확립하기 위하여 몇몇 건설정보관련 법규가 제도화되었다. 그러나 국내 건설정보 분류체계, 공정 공사비 통합관리(EVM), 프로젝트관리 정보시스템(PMIS)은 주요한 문제점을 내포하고 있다. 특히 현행 PMIS의 기능은 시공자 위주의 시스템으로 되어 있고, EVM이 적용되지 않아 발주자를 위한 보고, 분석, 예측기능이 매우 취약하다. 더욱이 EVM과 PMIS가 서로 분리된 체계로 운영되고 있어 발주자가 실시간으로 공정 및 공사비 정보를 확인할 수 없다. 본 연구의 목적은 PMIS가 EVM기능을 제공하고 사업참여자들이 제반정보를 공유할 수 있도록 WBS 구축방안과 EVM - PMIS 통합모델을 제안하여, E-비즈니스 업무환경하에서 PMIS를 효율적으로 운용할 수 있는 틀(framework)을 제공하는 것이다. EVM - PMIS 통합의 핵심은 EVM과 PMIS가 액티비티 기반의 동일한 운영체계를 갖는 것이다. 통합의 원리는 액티비티의 정보항목(field)을 PMIS의 공정 및 공사비관리 기능을 위한 하위모듈을 구성하는 관계형 데이터베이스 테이블(table)의 항목과 연계시키는 것이다. 따라서 액티비티의 계획공사비(PA), 달성공사비(EV), 실투입비(AC), 공정편차(SV), 공정수행지수(SPI), 공사비편차(CV), 공사비지출지수(CPI)는 PMIS의 공정 및 공사비 하위모듈을 위한 데이터베이스 테이블의 항목으로 연계된다.

Background: As hypertrophied myocardium predisposes the patient to decreased tolerance to ischemia and increased reperfusion injury, myocardial protection is of utmost importance in patients undergoing aortic valve replacement (AVR) for severe aortic valve stenosis (AS). Methods: Consecutive 314 patients (mean age, $62.5{\pm}10.8$ years; 143 females) with severe AS undergoing isolated AVR were included. Postoperative myocardial injury (PMI) was defined as 1) maximum postoperative creatinine kinase isoenzyme MB or troponin-I levels ${\geq}10$ times of reference, 2) postoperative low cardiac output syndrome or episodes of ventricular arrhythmia, or 3) left ventricular ejection fraction of less than 55% and decrease in left ventricle (LV) ejection fraction of more than 20% of the baseline value. Results: There were 90 patients (28.7%) who developed PMI. There were five cases of early death (1.6%), all of whom had PMI. On multivariable analysis, the use of histidine-tryptophan-ketoglutarate (HTK) solution instead of blood cardioplegia (odds ratio [OR], 3.06; 95% confidence interval [CI], 1.63 to 5.77; p=0.001), greater LV mass (OR, 1.04; 95% CI, 1.01 to 1.07; p=0.007), and increased cardiac ischemic time (OR, 1.13; 95% CI, 1.05 to 1.22; p<0.001) were independent predictors for PMI. Patients who had PMI showed significantly inferior long-term survival than those without PMI (p=0.049). Conclusion: PMI occurred in a considerable proportion of patients undergoing AVR for severe AS and was associated with poor long-term survival. HTK cardioplegia, higher LV mass, and longer cardiac ischemic duration were suggested as predictors of myocardial injury.

Purpose : This study was to determine the relationship between age and the mandibular cortical bone thickness on panoramic radiograph. Materials and Methods : Panoramic radiographs of 360 patients (180 men and 180 women) over 20 years old, who visited the Chonbuk National University Hospital from January to December in 2007, were assessed. The subjects were divided into 5 age groups. Five indices such as cortical bone thickness at the gonion (GI), antegonion (AI), and below the mental foramen (MI), the panoramic mandibular index (PMI), the mandibular cortical index (MCI) were measured on panoramic radiographs. Results : All five indices including GI, AI, MI, PMI, and MCI showed significant differences between third decade and over 8 decade groups (p<0.05). PMI, MI and GI showed significant differences with gender statistically (p<0.05). Conclusion : The mandibular cortical bone thickness showed negative correlation with age, and the value of the thickness (PMI, MI, and GI) was greater in men than in women.

We have investigated the EO characteristics generation of pretilt angle for a nematic liquid crystal (NLC) alignment with photoalignment method on three kinds of photopolymer surfaces using polymer substrates. The LC homogeneous alignment were observed on the PMI3CA (N-(phenyl)maleimide with 3-carbon chain cinnamoyl group) and PMIF (N-(phenyl)maleimide including fluoro cinnamoyl group). However, the homeotropic alignment on the PMI5CA(N-(phenyl)maleimide with 5-carbon chain cinnamoyl group) was obtained. Also, EO characteristics of the flexible photoaligned TN-LCD using PMIF surface are better than that of the flexible TN-LCD using PMI3CA surface. Also, the stable EO performances of flexible photoaligned VA-LCD using the PMI5CA surface was observed.

Estimation of postmortem interval (PMI) is a key issue in the field of forensic pathology. With the availability of quantitative analysis of RNA levels in postmortem tissues, several studies have assessed the postmortem degradation of constitutively expressed RNA species to estimate PMI. However, conventional RNA quantification as well as biochemical and physiological changes employed thus far have limitations related to standardization or normalization. The present study focuses on an interesting feature of the subdomains of certain RNA species, in which they are site-specifically cleaved during apoptotic cell death. We found that the D8 divergent domain of ribosomal RNA (rRNA) bearing cell death-related cleavage sites was rapidly removed during postmortem RNA degradation. In contrast to the fragile domain, the 5' terminal region of 28S rRNA was remarkably stable during the postmortem period. Importantly, the differences in the degradation rates between the two domains in mammalian 28S rRNA were highly proportional to increasing PMI with a significant linear correlation observed in mice as well as human autopsy tissues. In conclusion, we demonstrate that comparison of the degradation rates between domains of a single RNA species provides quantitative information on postmortem degradation states, which can be applied for the estimation of PMI.

Data mining technology is frequently used in identifying the intention of users over a variety of information contexts. Since relevant terms are mainly hidden in text data, it is necessary to extract them. Quantification is required in order to interpret user preference in association with other structured data. This paper proposes rating and comments mining to identify user priority and obtain improved ratings. Structured data (location and rating) and unstructured data (comments) are collected and priority is derived by analyzing statistics and employing TF-IDF. In addition, the improved ratings are generated by applying priority categories based on materialized ratings through Sentiment-Oriented Point-wise Mutual Information (SO-PMI)-based emotion analysis. In this paper, an experiment was carried out by collecting ratings and comments on "place" and by applying them. We confirmed that the proposed mining method is 1.2 times better than the conventional methods that do not reflect priorities and that the performance is improved to almost 2 times when the number to be predicted is small.

오픈소스 소프트웨어란 소스 코드를 공개한 상태로 공급되는 소프트웨어를 말한다. 오픈소스 소프트웨어의 개발 방법은 오픈소스 소프트웨어 프로젝트에 관심이 있는 개발자의 자발적인 참여로 이루어진다. 오픈소스 소프트웨어 개발 방식은 대부분 소프트웨어개발 방법론적인 측면이 적용되지 않기 때문에 일반적인 소프트웨어에 비해서 신뢰성이 떨어진다는 평가를 받는 원인이 되고 있다. 또한 일반 소프트웨어 개발과 비교해서 분산된 개발자들의 소스 공유 및 의견 교환과 합의 도출 방법이 필요하기 때문에 오픈소스 소프트웨어 개발에 일반적인 소프트웨어 개발 방법론을 적용할 수가 없다. 따라서 일반적인 소프트웨어 개발 방법과 프로젝트 관리 기법에서 공개 소프트웨어 개발을 위해 필요한 부분들을 도출하여 오픈소스 소프트웨어 개발에 적용할 수 있도록 커스터마이징한 오픈소스 소프트웨어를 위한 소프트웨어 개발 모델을 제안한다.

The osteoporosis is a disease that represents a reduction in the volume of bony tissue relative to whole bone volume. And mandible also may be affected. Such porotic mandible may influence the result of the surgery like dental implant surgery relating mandible. So, the author examed the panoramic view of 89 persons for finding the possibility of useful diagnostic parameters of osteoporosis. To know the correlationship between the condition of vertebra and mandible, bone marrow density of lumbar spine from 2nd to 4th, and the number of residual tooth, panoramic mandibular index (PMI), angular cortical bone thickness (ACT) and ramus cortical bone thickness (RCT) were compared. The result is that PMI and ACT have similar relative weak linear correlationship, RCT have very weak linear correlationship, the number of residual tooth have not linear correlationship.

A positive selectable marker system was adapted for transformation of mature embryo-derived calli of Indica rice (Oryza sativa L.) utilizing the PMI gene encoding for phosphomannose-isomerase that converts mannose-6-phosphate to fructose-6-phosphate. The transformed cells grew on medium supplemented with 3% mannose as carbon source and calli were selected on media containing various concentrations of mannose. Molecular analyses showed that the transformed plants contained the PMI gene. The results indicate that the mannose selection system can be used for Agrobacterium-mediated transformation of mature embryo in rice to substitute the use of conventional selectable markers in genetic transformation.
