Purpose: This study was conducted to identify the effects of a PMS nutritional education program for college nursing students. Method: Subjects consisted of nursing students(experimental group: 19, control group: 27). The experimental group participated in a PMS nutritional education program for 8 weeks (including group and individual involvement). Data was collected before and after the education, and measurement tools were premenstrual symptoms, PMS knowledge, and self health behavior. Results: After the intervention, the experimental group showed a significant increase in PMS knowledge(Z=6.32, p=.000) and self health behavior(t=3.00, p=.004) compared to the control group. After the intervention the experimental group showed a significant increase in PMS knowledge(Z=-4.64, p=.000) and self health behavior(t=-3.04, p=.005) than before the intervention. Conclusions: These results suggest that the short term effects of a PMS nutritional education program for nursing students was proven useful and the program should be applied to PMS nutrition education for PMS clients as well as health professionals.

In this study, developed economical and scientific Pavement Management System(PMS) that can produce suitable maintenance method through judgement and analysis of pavement condition exactly, to overcome past unscientific pavement management limitations. First, on the basis of data of the inside and outside of the country on PMS, composed logical algorithm such as pavement condition investigation and analysis, detailed naked eye investigation, whole system estimation etc., and it verified that this algorithm is suitable system through the inside and outside of the country PMS research examples and results of detailed naked eye investigation. Also, developed easily usable PMS program and PMS_GIS program with such logical algorithm.

현재 프로젝트를 통해 발생되는 데이터를 수작업으로 관리하는 데는 한계가 있고, 다량의 주요 정보를 효과적으로 관리하기 위해서는 표준화 된 프로젝트에 대한 관리가 필요하다. 본 연구에서는 프로젝트를 통해 발생되는 여러 가지 데이터들을 체계적으로 관리해 줄 뿐만 아니라, 컴퓨터의 사용이 제한되는 곳에서도, 모바일을 통해서 공간의 제약 없이 언제든 프로젝트의 진행상황을 알아볼 수 있고, 각종 결제대기 문서에 대해서 결제를 진행할 수 있는 프로그램에 대해서 연구했다.

In this paper, a PMS(Pavement Management System) is presented for the public agency who wish to execute rational repair by referring to asset management information regarding road pavement. The aim of the paper is to provide the decision makers with the planning information regarding maintenance strategies for efficient road pavement management. We found that life cycle cost can be minimized and repair cost in each year fluctuates when repeating repair at the IRI management level. The validity of PMS application presented in this paper is investigated through case studies for conducted for 22 national highway road sections in Korea.

기존 E-mail 프로그램은 비싼 통신요금과 저속의 위성통신 환경에서 최대한 통신비용을 줄이기 위한 목적으로 개발되었고, 그 결과 프로그램의 유연성이 떨어져 새로운 기능의 추가나 업그레이드가 용이하지 않았다. 또한 기존 프로그램의 경우는, E-mail 전용 프로그램으로서 다양한 육상과 해상간의 업무용 프로그램과 연동시키는 데에 어려움이 많았으며, 개발자 입장에서도 무선 위성통신의 특성상 개발이 쉽지 않았다. 따라서 본 논문에서는 기존 프로그램과는 달리 데이터를 패킷으로 분리하여 전송함으로써 프로토콜에 유연성을 주고, 실시간으로 여러 종류의 데이터를 전송할 수 있게 하여 동시에 E-mail뿐만 아니라, 모니터링 데이터, SMS, PMS를 위한 데이터베이스 등의 다양한 데이터를 전송할 수 있도록 설계 및 구현하였다. 또한 프로그램 개발자들이 까다로운 위성통신 환경을 몰라도 쉽게 개발할 수 있게 하고자, 컴포넌트를 윈도우즈 서비스 프로그램화 하였다.

The purpose of this study was to identify the relationships between perceived stress, ego-resilience, and premenstrual syndrome(PMS) and investigate the factors affecting PMS in female college students. The study participants were 215 female college students in Gyeunggi province. Data were collected from October 10 to November 10, 2017, using self-report questionnaires. Collected data were analyzed using descriptive statistics, Pearson correlation coefficients, and multiple regression analysis. PMS was positively correlated with the perceived stress and negatively correlated with ego-resilience. Eating habits, interference with daily life by menstruation, perceived stress accounted for 44.4% of variance in PMS. Based on these results, it is necessary to develop a management program that integrates psychological factors and lifestyle improvement including dietary habits, as well as efforts to manage menstrual symptoms in order to alleviate the premenstrual syndrome of female college students.

Pavement distresses are one of the most important data for pavement management systems. Inspection machines and its related programs have been used for operating tools in PMS developed in advanced countries. In Korea imported machines and programs for the length price ale utilized to get information of pavement condition from the field This study is launched for developing the program which can detect cracks on asphalt pavement due to many drawbacks in current PMS operation such as improper maintenance work and long resting period when it was broken. The focus of this study is to define principles to analyze pavement surface with digital image processing techniques, to test property of pavement images and to suggest an algorithm that reduces noises at test. To test images, the camera attached on the Automatic Road Analyser(ARAN) was used. Through the FFT images, histogram and statistical values of pavement images, it was found that the images had many noises with high-frequency components against general images, and it was difficult to subdivide pavement images into background or crack. Through several testing with various filters for noise reduction a 3X3 median filter was suggested to reduce noises effectively.
