본 연구는 슈퍼박테리아로 불리는 메티실린 내성 황색포도알균에 대한 간호대학생의 지식과 병원실습 중 감염 예방 이행 수준과 영향요인을 파악하고자 시행하였다. 2016년 10월 14일부터 11월 30일까지 병원실습 경험이 있는 5개 대학의 간호학과 4학년 학생을 편의 추출하여 설문조사 하였고, 성실히 응답한 총 234명의 자료를 분석하였다. 연구결과, MRSA 지식은 100점으로 환산 시 52.0점이었고, MRSA 감염 예방 이행 수준은 89.41점이었다. MRSA 감염 예방 이행에 영향을 미치는 요인으로는 MRSA 교육과 실습 중 MRSA 감염 가능성에 대한 인식이 유의하였다. 그러므로 MRSA 감염 예방 이행을 증진시키기 위해서는 단순한 지식 제공보다 감염 가능성에 대한 올바른 인식을 포함한 병원실습에서 적용 가능한 교육 프로그램 개발과 교육이 필요하다.

본 연구는 충남 보령시 청라면에 위치한 폐광산광미로부터 청라저수지 저니토에 이르기까지 토양에 존재하는 중금속과 자연방사능원소간의 발생과 분포에 대하여 조사하였다. 조사 결과 광미영향 지점과 비영향 지점간의 중금속과 자연방사능원소 함량에는 현저한 차이가 있었다. 중금속의 분포 특성은 Pb ($1.32-29.96mg\;kg^{-1}$, 평균 $10.44mg\;kg^{-1}$), Cd ($0.15-0.76mg\;kg^{-1}$, 평균 $0.51mg\;kg^{-1}$), Cu ($0.28-49.67mg\;kg^{-1}$, 평균 $12.43mg\;kg^{-1}$), Cr ($1.31-13.18mg\;kg^{-1}$, 평균 $4.87mg\;kg^{-1}$)으로 조사 되었다. 그리고 Pb와 Cu의 조사지점별 함량 변이는 다른 중금속에 비해 매우 높았다. 건조한 토양을 기준으로 한 자연방사능 함량은 Pb-210 ($4.87dpm\;g^{-1}$), Th-234 ($3.52dpm\;g^{-1}$), Ra-226 ($2.88dpm\;g^{-1}$), Ra-228 ($7.30dpm\;g^{-1}$), K-40 ($58.06dpm\;g^{-1}$) 순으로 나타났으나 핵실험 등의 낙진으로 인하여 대기로부터 유입되는 Cs-137은 발견되지 않았다. 이러한 결과를 기준으로 하여 석탄광미 자체에 포함된 자연방사능 함량과 조시지점에서 조사된 자연방사능 함량을 비교하였을 때 Pb-210 (4.41%), Th-234 (3.60%), Ra-226 (2.09%)로 매우 낮은 비율로 조사되었으나 Ra-228 (266%)과 K-40 (308%)은 석탄광미보다 광미장 외의 지점에서 더 높은 비율로 존재함을 알 수 있었다. 그리고 중금속과 자연방사능의 발생 정도 사이에는 상관관계가 낮았다.

The purpose of this study is to investigate the effects of the SW-STEAM program by utilizing ozobot coding for elementary science class. The developed SW-STEAM program was applied to $5^{th}$ grade students of S elementary school located in B city. The participants were divided into an experimental group which is consisted of 22 students and a comparative group comprised 22 students. And they were engaged in different teaching and learning methods during 11 class hours. The experimental group participated in the SW-STEAM program, the comparative group was taught by using a traditional instruction. The main results of this study are like followings. The SW-STEAM program had a positive effect on elementary school students' basic science process skill, science learning motive, science achievement. Therefore, the SW-STEAM program by utilizing ozobot coding could be meaningful works to encourage students' basic science process skill, science learning motive and science achievement, and more studies on developing SW-STEAM program are needed.

This study was conducted to determine the main effects of the parity and farrowing season on gestation length and newborn pigs on the basis of the data obtained from 234 litters of Landrace breeds raised at an integrated swine farm in Kyunggy province from January 1991 to December 1992. The results obtained are summarized as follows ; 1. The average gestation length was 115.37 days, and 114.64 days of 8th parity and over was shorter than those of other parities. 2. The averages of litter size and litter size alive per sow were 9.91 and 9.50 heads. The litter size horn at 1st parity was smaller than at other parities, and the litter size in spring was larger than in summer, autumn or winter. 3. The averages of birth weight per litter and pig were 13.53 kg and 1.37 kg. The effect of farrowing season for each litter weight(p<0.01) and pig weight(p<0.05) at birth was significantly higher in spring than other seasons. 4. Incidence of malformation and stillbirth at birth was 4. 10%, and it at 8th parity and over showed the highest rate(7.50%).

Purpose: The purpose of this study was to investigate factors predicting internet game addiction in higher grade elementary schoolers according to gender. Methods: The participants were 898 elementary school students who were in 5th and 6th grade. Data were collected via a structured questionnaire from October 1 to November 20 2012 and analyzed using descriptive statistics, $x^2$ test and logistic regression with the SPSS/WIN 23.0 program. Results: The prevalence rate of internet game addiction group was 8.8% (boys 7.1%, girls 1.7%). In terms of gender difference, it was found that girls' stress coping behaviors were more passive than male students (t=-3.27, p=.001). In boys, variables that predicted internet game addiction were aggressive coping, active coping, internet gaming hours per day and academic achievements. In girls, variables that predicted internet game addiction were aggressive coping, close friends and academic achievements. Conclusion: The findings from this study indicate there is a need to develop positive stress-coping behaviors programs and prevent internet game addiction in higher grade elementary school students.

Purpose: This study was conducted to understand the subjective symptom rate of musculoskeletal disease of male taxi drivers and comprehend general features, health behavior features, and factors related to the subjective symptoms of musculoskeletal system depending on the level of job stress. Methods: The participants were 206 male taxi drivers from 4 transportation companies in the Seoul and Gyeonggi areas. The investigation was conducted from July 20th 2012 to August 20th 2012 through a self-administered questionnaire survey. Results: The participants who exercised less than three times per week complained about the subjective symptoms of the musculoskeletal system (p=.016) 13.770 times as more as than those of the participants who exercised more than three times per week the participants who had a higher level of job stress complained about the subjective symptoms of the muscular skeletal (p=.011) 1.051times as more as than those who had a relatively lower level of job stress. Conclusion: This study recommends that it is necessary to provide exercise programs and arrange various plans reducing job stress to prevent muscular skeletal disease and minimize the disease susceptibility of taxi drivers.
