The present study was conducted to analyze the causes of stress on the part of Korean radiological technologists depending on their working environments. For this purpose, 890 questionnaires were distributed to and collected from radiological technologists who were working at 44 general hospitals in 16 cities and provinces of Korea during the period from the mid July to the end of August 2003. The collected data were compared between regions, divided into the capital, metropolitan, medium and small cities, whose results are as follows: 1. As factors affecting working conditions, drinking was found to exert more influence on radiological technologists in small- and medium-sized cities, while loyalty to immediate seniors and organizations was the one producing greater influence on them in metropolitan cities than other cities. Overall, position, job satisfaction and physical condition seemed to have a great effect on them (p<0.001).2. In terms of factors related to their roles, job satisfaction and physical condition played in general a greater role for radiological technologists (p<0.001). Immediate seniors and behavioral conducts were also found to have a lot influence on them (p<0.01).3. As for job conflicts, the kind of medical institutions seemed to exercise a great deal of impact on radiological technologists (p<0.05), while colleagues, immediate seniors, job satisfaction and physical conditions also produced a lot of influence on them as a whole (p<0.001).4. Regarding job autonomy, radiological technologists were found to have been less influenced by position in metropolitan cities and by immediate seniors in the capital city (p<0.01). As a whole, however, age and job satisfaction acted as decisive factors of influence on them (p<0.001). 5. Among factors related to job burden, gender played a bigger role for radiological technologists in metropolitan cities as the kind of medical institutions did in small- and medium-sized cities. Centrally, job satisfaction and behavioral conducts exercised a great impact on them (p<0.001).6. Job stability seemed to be more immensely linked to gender and physical conditions in metropolitan cities whereas position did more in the capital city. In general, how ever, job satisfaction produced a far-reaching (p<0.001).

A survey was conducted to 890 radiological technologists working at 44 general hospitals of 16 cities and provinces across the county to determine their stress level according to regions divided into the capital city, metropolitan areas and small- and medium-sized cities. For this purpose, such factors as their working environment, role playing, job conflict and job burden were compared and analyzed according to the regions. The findings may be summed up as follows: 1. In terms of working environment, radiological technologists in the capital city were found to have the least stress(23.46), followed by those in metropolitan areas(24.53) and small- and medium-sized cities(24.85). There was a significant difference according to the regions as for the item 'worry about influence of radioactive contamination(genetic, decisive and plausible)(P<0.001). 2. As for role playing, radiological technologists in small-and medium-sized cities appeared to receive the highest stress(l8.25) followed by metropolitan areas(l7. 71) and the capital city(l6.69). There was a statistically significant difference(P<0.001) according to the regions 3. Regarding job conflict, those who work in small- and medium-sized cities turned out to get the highest stress(15.66) compared to those in metropolitan areas(15.35) and the capital city(l4.44). In terms of job autonomy, there was no significant result from the survey in spite of the difference between metropolitan areas(14.87), small- and medium-sized cities(l4.79) and the capital city(l4.66). 4. Little difference was detected according to the regions as far as the job burden(excessive or too little) was concerned. But their was a significant regional difference in tenns of patient-related factors with the capital city(11.50), small- and medium-sized cities(l0.75), and metropolitan areas(1.63)(P<0.001).

This study is aimed at examining the relationship between health behaviors practices and physical and psychological stresses of radiological technologists who are working at general hospitals across the country. For this purpose, a survey was conducted to 890 subjects by means of questionnaires from the middle of July to the end of August 2003, which resulted in the following outcomes: 1. From the technical and statistical analysis into the physical and psychological states, the item 'I feel miserable and dejected' scored the highest points of (3.91), implying that most subjects got heavily stressed, while the item 'Life is worth living' recorded (2.59), representing that only a few of them got less stressed. 2. With regard to an analysis of variance depending on their regular exercise, a significant difference appeared in 7 items(Pl, P2, P5, P6, P12, P17, and Pl8)(P<0.05). 3. Out of analysis into such variance as smoking, significant results were found in the items 'I become uncomfortable or disturbed at night' and 'I can solve my own problems'(P<0.05), while no significant difference was confirmed in other items regardless smoking. 4. From the T-test conducted to the independent sample depending on the drive under the influence, a significant difference was shown only in the item 'I feel very exhausted, even eating is a labo'( P<0.05). 5. The T-test with the independent sample of drinking coffee, the item 'I am satisfied with the method and the procedure of things I do' turned out to be significant( P<0.05) while no particular difference was confirmed in other items. In conclusion, it was revealed from the study that the physical and psychological states and health-related practices of radiological technologists seemed to be more affected by regular exercise than by smoking or drinking wine or coffee, a result confirming that the health-related acts are closely associated with the socio-psychological stresses. It is, therefore, strongly suggested that the practice of health-related acts to properly control stress will contribute to promoting health and pre venting disease of radiological technologists.

골다공증은 골절의 위험도가 증가하는 질환으로, 본 연구에서는 이중에너지 엑스선 흡수계측법(DXA)을 이용하여 허리뼈의 회전과 기울기에 따른 골밀도를 비교 분석하였다. 실험 결과 허리뼈의 회전에 따른 골밀도는 감소하지만 허리뼈의 기울기 변화에서는 그 결과는 예측할 수 없었다. 이러한 이유는 허리뼈의 기울기 변화가 허리뼈 1번과 4번사이 일부분에서 겹침으로 인하여 뼈의 전체 면적과 골밀도가 변화한 결과로 판단되어진다. 즉, 방사선사는 정확한 골밀도 결과 값을 얻기 위하여 허리뼈의 회전방지와 기울기에 따른 겹침을 방지하기 위한 노력이 필요할 것으로 판단되어진다.

본 연구는 방사선사의 직무스트레스 요인을 분석하여 직무 효율성을 높이고 조직관리방안을 마련하고자 수행하였다. 자료수집은 구조화된 설문지를 사용하여 부산시내에 근무하는 방사선사 261명을 대상으로 하였다. 회수된 자료에 대한 분석은 SPSS/PC+ Win 13 버전을 사용하였으며, 집단 간 차이 검증을 위해 일원분산분석(oneway ANOVA)을 시행하였으며, 직무스트레스가 조직효과성에 미치는 영향 분석을 위하여 중다회귀분석(Multiple regression)을 시행하여 검증하였다. 그 결과 첫째, 연령에 따른 직무스트레스는 30대의 경우 개인적인 문제에서 20, 40, 50대는 의사소통이 가장 큰 스트레스요인으로 나타났다. 부서에 따른 직무스트레스는 집단 간 통계적인 차이를 보이지 않았다. 둘째, 조직 효과성분석 결과, 연령의 경우 20대에서, 부서의 경우 종양학과가 조직몰입, 직무만족 모두에서 높은 것으로 평가 되었으며, 집단 간 통계적으로 유의한 차이를 나타냈다. 셋째, 직무스트레스 하부요인 중 의사소통의 문제가 통계적으로 유의하게 조직효과성에 영향을 미치는 변인으로 나타났다. 그러나 행정적인 문제, 개인적인 문제는 통계적으로 유의한 차이를 보이지 않았다. 따라서 조직 내 또는 타 부서와의 의사소통이 잘 될수록 직무스트레스는 줄어든다. 즉 원활한 의사소통을 통한 조직 내 갈등을 줄임으로써 조직효과성을 높일 수 있다.

본 연구는 영상의학과에 내원한 족부환자를 대상으로 족부 X선 검사 시 주상골(navicular)의 관찰이 어려운 점을 바탕으로 환자의 position과 X선관 각도의 변화를 주어 어떠한 position과 X선관 각도에서 주상골의 관찰이 용이한지를 알아보고자 하였다. 주상골 관찰을 위해 실험대상자의 position은 Foot AP, internal oblique, external Oblique position의 세 가지로 하였다. T-F angle(Tibia-Foot angle)은 $90^{\circ}$와 $135^{\circ}$로 정의하였고, X선관 각도는 $0^{\circ}$, $5^{\circ}$, $10^{\circ}$, $15^{\circ}$, $20^{\circ}$, $25^{\circ}$로 정의하여 실험한 후 획득한 영상을 비교 평가하였다. 실험결과, Foot AP position에서 T-F angle이 $90^{\circ}$인 경우 X선관 각도가 $15^{\circ}$일 때 설상골과 주상골의 겹침 정도는 3%이었고 블라인드 테스트 결과는 4.89점으로 골절의 판독 용이성이 가장 높았으며, T-F angle이 $135^{\circ}$경우에는 X선관 각도가 $15^{\circ}$일 때 설상골과 주상골의 겹침 정도는 5%이었고 블라인드 테스트 결과는 4.30점으로 판독 용이성이 가장 높았다. Foot internal oblique position에서는 T-F angle이 $90^{\circ}$인 경우 X선관 각도가 $0^{\circ}$일 때 설상골과 주상골의 겹침 정도는 4%이었고 블라인드 테스트 결과는 4.70점으로 가장 높았으며, T-F angle이 $135^{\circ}$경우에는 X선관 각도가 $0^{\circ}$일 때 그 겹침 정도는 5%이었고 블라인드 테스트 결과는 4.55점으로 가장 높게 나타났다. Foot external oblique position에서 T-F angle이 $90^{\circ}$인 경우 X선관 각도가 $15^{\circ}$일 때 설상골과 주상골의 겹침 정도는 4%이었고 블라인드 테스트 결과는 4.85점으로 가장 높았으며, T-F angle이 $135^{\circ}$경우에는 X선관 각도가 $15^{\circ}$일 때 그 겹침 정도는 5%이었고 블라인드 테스트 결과는 4.75점으로 가장 높게 나타났다. 결론적으로, 본 연구를 통하여 X 선 족부검사에서 각 position에 해당하는 주상골 관찰에 용이한 T-F 각도와 X선관 각도를 확인할 수 있었으며, 향후 본 연구 결과를 바탕으로 주상골 골절 판독에 유용한 참고자료가 될 수 있을 것으로 여겨진다.
