  • PURPOSES : The purpose of this study is to develop a regression model to predict the International Roughness Index(IRI) and Surface Distress(SD) for the estimation of HPCI using Expressway Pavement Management System(PMS). METHODS : To develop an HPCI prediction model, prediction models of IRI and SD were developed in advance. The independent variables considered in the models were pavement age, Annual Average Daily Traffic Volume(AADT), the amount of deicing salt used, the severity of Alkali Silica Reaction(ASR), average temperature, annual temperature difference, number of days of precipitation, number of days of snowfall, number of days below zero temperature, and so on. RESULTS : The present IRI, age, AADT, annual temperature differential, number of days of precipitation and ASR severity were chosen as independent variables for the IRI prediction model. In addition, the present IRI, present SD, amount of deicing chemical used, and annual temperature differential were chosen as independent variables for the SD prediction model. CONCLUSIONS : The models for predicting IRI and SD were developed. The predicted HPCI can be calculated from the HPCI equation using the predicted IRI and SD.

  • Objective: To compare the blood glucose levels, insulin concentrations, and insulin resistance during the two phases of the menstrual cycle between healthy women and patients with premenstrual syndrome (PMS). Methods: From January of 2011 to the August of 2012, a descriptive cross-sectional study was performed among students in the School of Medicine of Jahrom University of Medical Sciences. We included 30 students with the most severe symptoms of PMS and 30 age frequency-matched healthy controls. We analyzed the serum concentrations of glucose, insulin, and insulin resistance by using the glucose oxidase method, radioimmunometric assay, and homeostasis model assessment of insulin resistance equation, respectively. Results: No significant differences between the demographic data of the control and PMS groups were observed. The mean concentrations of glucose of the two study groups were significantly different during the follicular and luteal phases (p=0.011 vs. p<0.0001, respectively). The amounts of homeostasis model assessment of insulin resistance of the two study groups were significantly different in the luteal phase (p=0.0005). Conclusion: The level of blood glucose and insulin resistance was lower during the two phases of the menstrual cycle of the PMS group than that of the controls.

  • Recently, Information System (IS) development projects such as the next generation IS project of the financial business domain have shown tendency to become large and complex. Accordingly, a large number of enterprises have introduced a Project Management Office (PMO) to successfully manage multiple complex large-scaled projects. Many researches and empirical studies have proved the positive results of PMO-based projects. For example, most PMO-based projects have been accomplished successfully without exceeding the planned deadline and budget. However, even in the case of PMO-based projects, participants are still supported by legacy Project Management Systems (PMS) developed without considering the PMO. It implies that recent large projects are hardly performed efficiently because of the large gap between the legacy PMS tools developed only for single small projects and the real process of PMO-based project management. Therefore, we attempt to design and develop a PMO-based PMS in which the role and responsibility of PMO are completely implemented. To demonstrate our systems practicality, we applied the devised system to the real project management cases of "K" bank in The Republic of Korea. According to the results of case analysis, all of the four projects supported by our PMO-based PMS have been completed without exceeding planned deadline and budget, and the quality of their final outcome is appraised to be superior.

  • We report the spatial distribution of early-type stars and pre-main-sequence (PMS) stars around the starburst type young open cluster Westerlund 2. The early-type were selected from UBVI photometric data, while the PMS members were identified from their X-ray emission and mid-infrared excess. The northern clump of the cluster is composed mainly of PMS stars detected in both optical and X-ray and seems to be coeval to the cluster, while PMS stars in the bright bridge region are highly obscured in optical wavelength. The bright bridge appear to be an on-going star forming region possibly triggered by the strong radiation field from both sides-massive stars in Westerlund 2 and WR 20b. We also found that there are many early-type stars not only in the cluster but also farther from the cluster up to several times of the cluster radius. These early-type stars are well aligned from east to southwest of the cluster. We conclude these early-type stars are members of an OB association in the RCW 49 nebula. This report indicates there is a complex star formation history in Westerlund 2 and its surrounding H II region, the RCW 49 nebula.

  • 본 연구는 최근 들어 DDoS 공격이 단순히 서비스를 방해하는 것에서 벗어나, 다양한 공격 기법을 혼합한 멀티벡터(Multi-Vector) 공격으로 발전하고 있다. 이러한 멀티벡터 공격은 DDoS 공격과 더불어 악성코드를 감염시켜, 내부 정보 유출 및 좀비PC를 만들어 DDoS 공격용에 활용될 경우에는 기존의 DDoS 공격 및 악성코드 감염에 대한 방어 전략으로는 한계점이 있다. 따라서 본 논문에서는 다양한 방법을 이용한 멀티벡터 공격을 효과적으로 방어하기 위한 Reverse Proxy Group과 PMS(Patch Management Server)를 제시하고자 한다.

  • 스마트폰이나 태블릿 PC와 같은 스마트 디바이스의 확산은 방송과 통신의 융합을 질적으로 변화시켜 다양한 미디어를 창출하고 있다. 스마트 디바이스는 개인용 기기이기 때문에 사용자 프로파일(연령, 성별, 직업 등)과 위치를 바탕으로 고객 맞춤식 환경을 제공할 수 있고, 네트워크 기능을 가지고 있기 때문에 양방향 소통이 가능한 미디어 플랫폼이라고 할 수 있다. 본 논문에서는 스마트 디바이스를 활용하여 개인화된 메시지를 전달할 수 있는 메시지 신디케이션(PMS: Personalized Message Syndication)을 제안하고 비즈니스 측면과 기술적인 측면을 분석한다. 본 논문에서 제안한 PMS는 스마트 미디어로서 소비자에게 맞춤식 정보를 제공하고 생산자에게는 소비자의 공감과 참여를 유도할 수 있는 마케팅 도구를 제공하고 있다.

  • Purpose: The purpose of this study was to identify the relationships between life style, menstrual attitude and premenstrual syndrome in nursing students. Methods: The study participants were 246 nursing students of a university in Gyeunggi province. Data were collected by a self-administered questionnaire from May to June, 2012. Collected data were analyzed using the SPSS/WIN 20.0 program with descriptive statistics, Pearson correlation coefficient, t-test, one-way ANOVA and Scheffe test. Results: Students who had undesirable alcohol habits (r=.15, p=.020) and negative menstrual attitude (r=.17, p=.009) experienced more a severe premenstrual syndrome (PMS). Students with dysmenorrhea had more severe PMS (F=12.41, p<.001) and a negative menstrual attitude (F=6.18, p<.001). Conclusion: These finding suggest that PMS would be alleviated by nursing interventions to improve alcohol habits and decrease negative menstrual attitudes, and nursing interventions for dysmenorrhea would be helpful in PMS management in nursing students. Further studies on the development of nursing interventions related to these factors are needed for PMS management.
