벼의 유묘 생육과 광합성 효율에 대한 저선량 방사선과 생장조절물질 간의 상승작용 효과를 확인하기 위해 4년 된 종자로 기내실험과 온실실험을 수행하였다. 기내실험에서 관찰한 종자 발아의 경우 방사선을 조사한 IBA 0.001 ppm 처리구에서 가장 높은 값을 보였다. 또한, 파종 6일 후 측정한 유표 생육은 방사선 무 조사구보다 방사선을 조사한 GA₃와 IBA 처리구에서 대체로 높은 값을 보였으며, 그 중 IBA 0.001 ppm 처리에서 저선량 방사선과 생장조절물질간의 유의성 있는 상승작용 효과를 확인 할 수 있었다. 저선량 방사선을 조사 한 후 IBA 0.001ppm을 처리하여 관찰한 온실 실험에서도 유묘 생육에서의 상승작용 효과를 확인할 수 있었다 광합성 효율을 확인하기 위해 측정한 엽록소 형광은 생장조절물질에 의해서만 차이를 보여, IBA 처리에 의해 광계 2의 양자 수율을 나타내주는 Φ_(PSⅡ)와 광화학적 소멸을 나타내는 qP는 증가하였고 비광화학적 소멸을 나타내는 형광지표인 qN은 감소하였다. 이러한 결과를 통해 저선량 방사선을 조사한 후 생장조절물질을 처리하였을 때 벼의 종자 발아와 더불어 생육이 두 요인간의 상승작용 효과로 촉진됨을 확인할 수 있었다. To investigate the synergistic effects of low dose gamma irradiation and growth regulators on the growth and photosynthesis in rice (Oryza sativa L.), laboratory and greenhouse experiments were conducted using 4-year-old rice seeds. In the laboratory experiment, the germination rate was increased in 0.001 ppm IBA treatment, showing the synergistic effect of gamma irradiation and growth regulators. The seedling growth was increased by treatment of GA₃ and IBA, the irradiated groups having higher than the non-irradiated ones. Particularly, it was remarkable in 0.001 ppm IBA. In greenhouse experiment, seedling growth was increased in response to a combination of gamma irradiation and 0.001 ppm IBA. Effective quantum yield of PSⅡ (Φ_(PSⅡ)) and photochemical quenching (qP) were increased, while non-photochemical quenching (qN) was decreased by 0.001 ppm IBA. A synergistic effect of gamma irradiation and IBA was only found in seedling growth. The present results suggest that low dose gamma irradiation and growth regulator could synergistically stimulate seedling growth.

Purpose: The purpose of this study was to identify the degree of Job stress and Coping of the nurses in ICU and Cancer ward, and to compare the Job stress and Coping between two groups, and finally to get the basic information about the adequate method to promote Coping about Job stress of the nurses in ICU and Cancer ward. Method: The subjects of this study were 131; 62 nurses in ICU and 69 nurses in Cancer ward. Data were collected from 27th August to 14th September in 2007. The instruments for this study were Job stress scale(55 items) developed by Kim(1989), and Coping scale(32 items) developed by Lazarus and Folkman(1984) and revised by Han and Oh(1990). For the data analysis, SPSS PC/win 12.0 program was utilized for descriptive statistics, χ²- test, t-test, Pearson correlation. Result: The results of this study were the followings; The mean score of Job stress(range 1-5) was 2.93 in ICU nurse and 2.58 in Cancer ward nurse. There was a significant difference (t=4.453, p<.01)between them. There were significant differences in subscale of Job stress between the two groups, such as Nursing job(t=3.717, p<.01), Job circumstances(t=4.558, p<.01), Personal relations(t=3.425, p<.01), Hospital administration and ward management(t=2.94, p<.01). The mean score of Coping(range 1-4) was 2.55 in ICU nurse, and 2.54 in Cancer ward nurse; there was no significant difference. But one subscale of the Coping(Search of social support) showed significant difference(t=-2.865, p<.01). There was no significant correlation between Job stress and Coping of ICU nurse vs Cancer ward nurse except one subscale in cancer ward(correlation between Nursing Job and Coping). Conclusion: The ICU nurse is higher than the Cancer ward nurse in the Job stress score significantly and lower than the Cancer unit nurse in the Coping. Based on the study results, it is needed the program development using the Coping methods in accordance with ward speciality to relieve Job stress.

저선량 γ선 조사가 고추의 광합성과 광 스트레스 경감에 미치는 효과

이혜연,백명화,박순철,박연일,김재성,Lee, Hae-Youn,Baek, Myung-Hwa,Park, Soon-Chul,Park, Youn-Il,Kim, Jae-Sung 한국환경농학회 2002 한국환경농학회지 Vol.21 No.2

고추 종자에 저선량 $\gamma$선을 조사시킨 고추 식물체의 생육과 광합성 능 및 광 스트레스 반응에 미치는 영향을 조사하였다. 저선량 4 Gy가 조사된 고추 식물체에서 광합성에 의한 산소발생이 대조구에 비해 1.5배정도 높은 것으로 나타났다. 고추 잎에 900 ${\mu}mol/m^2/s$의 빛의 세기로 광저해를 4시간 유도하였을 때 최대 광합성능 (Pmax)이 대조구의 경우 20%정도 감소되는 반면 4 Gy 조사구는 3% 정도의 감소를 보였다. Fv/Fm는 광저해가 진행됨에 따라 감소되는 경향을 보이며 대조구의 경우 4시간 처리시 Fv/Fm 값이 50% 정도 감소되는 것을 볼 수 있었다. 반면 4 Gy 조사구는 Fv/Fm값이 대략 37%정도 감소되어 대조구에 비해 광 스트레스에 대해 덜 민감한 것으로 나타났다. Fo는 광저해가 진행됨에 따라 거의 변화가 없었으며 대조구나 4 Gy조사구 사이의 차이도 거의 없는 것으로 나타났다. 광계II의 광양자 수율인 $\Phi_{PSII}$과 광계II 반응중심에 의한 여기 포획률을 나타내주는 1/Fo-1/Fm 또한 광저해가 진행됨에 따라 감소되었으며 4시간을 처리했을 경우 각각 대조구는 47%, 4 Gy 조사구는 30%의 감소를 볼 수 있었다. 비광화학적 소멸인 NPQ는 광저해가 진행됨에 따라 감소되는 경향을 보였으나 대조구와 4 Gy 조사구간에 차이는 없는 것으로 나타났다. 이러한 결과를 볼 때 종자의 종피를 투과한 저선량의 $\gamma$선이 식물의 광합성을 증대시키고 동시에 광 스트레스에 대한 저해를 감소시키는 것으로 보인다. The effect of low dose $\gamma$ radiation on photosynthesis and the reduction of photoinhibition in red pepper plant was investigated. The seedling height leaf width and leaf length of pepper were stimulated in plants grown from seeds irradiated with the low dose of 4 Gy. The $O_2$ evolution in the 4 Gy irradiation group was 1.5 times greater than in the control. To investigate the effect of low dose $\gamma$ radiation on response to high light stress, photoinhibition was induced in leaves of pepper by illumination of high light (900 $\mu mol/m^2/s$). Pmax was decreased with increasing illumination time by 20% in the control, while hardly decreased in the 4 Gy irradiation group. The photochemical yield of PSII, estimated as Fv/Fm, was decreased with increasing illumination time by 50% after 4 hours while Fo did not change. However, Fv/Fm in the 4 Gy irradiation group was decreased by 37% of inhibition, indicating that the photoinhibition was decreased by the low dose $\gamma$ radiation. Changes in the effective quantum yield of PSII, $\Phi_{PSII}$, and 1/Fo-1/Fm, a measure of the rate constant of excitation trapping by the PSII reaction center, showed similar pattern to Fv/Fm. And NPQ was decreased after photoinhibitory treatment showing no difference between the control and the 4 Gy irradiation group. These results showed the positive effect of low dose $\gamma$ radiation on the seedling growth and the reduction of photoinhibition.

본 연구의 목적은 간호대학생을 대상으로 교육서비스품질을 교육프로그램, 교수, 교육환경, 명성과 취업으로 구성하여 학생만족을 통한 행동의지에 미치는 영향을 파악하고자 하였다. 경남 1개 대학 간호대학생 350명을 대상으로 설문 조사를 하였으며, 최종 321부를 SPSS 21.0과 AMOS 21.0 프로그램을 사용하여 통계분석을 하였다. 연구결과를 요약하면 다음과 같다. 간호대학생이 인지하는 교육서비스품질의 구성개념 모두 학생만족에 유의한 정(+)의 영향이 있으며 명성과 취업, 교육프로그램, 교육환경, 교수의 순으로 영향력의 차이가 있음을 확인하였다. 또한, 학생만족은 행동의지에 유의한 정(+)의 영향이 있음을 확인하였다. 따라서 간호대학생의 교육서비스품질을 높이기 위한 질 관리가 필요하며 영향력의 상대적 크기를 반영하여 체계적인 관리가 요구된다. This study aimed to verify how nursing students' willingness to behave in a specific way based on satisfaction is affected by the quality of nursing education service in terms of educational program, professor, educational environment, and reputation and employment. For this, the research conducted a questionnaire survey of 350 nursing students at one college in Gyeongnam, through which 321 sheets of the form were finally collected, and processed using the SPSS 21.0 and AMOS 21.0 Programs. Summarizing the findings of this study, each factor of the abovementioned quality had a significantly positive influence on nursing students' satisfaction. The biggest influential was reputation and employment, followed by educational program, educational environment, and professors. Also, that satisfaction significantly, positively affected those students' willingness to do specific behaviors. In conclusion, education services for nursing students require quality management which reflects relative differences in influential power among factors as mentioned above.
