본 연구는 의원에 근무하는 방사선사의 복지만족요인을 분석하기 위한 연구로 복지의 만족요인과 만족 수준 및 개선해야할 사항들을 분석하기 위해 실시하였다. 연구에 사용한 도구는 설문지로 2014년 7월14일 부터 2015년 3월31일까지 경남에 소재하는 의원에 근무하는 방사선사를 대상으로 설문지 총150부를 배부 하여 연구에 적합한 130부를 SPSS 18.0 통계 프로그램을 이용하여 분석하였다. 복지에 대한 요인으로는 생 활, 금융, 교육, 의료, 문화 등을 복지요인으로 하였으며, 인구사회학적특성으로는 성별, 결혼, 학력, 연령, 근속연수를 기준으로 하였다. 복지요인별 만족수준을 살펴보면 생활복지(2.74±.65), 금융복지(2.42±.74), 교 육복지(2.24±.72), 의료복지(2.68±.69), 문화복지(2.27±.64)로 복지요인에 대한 만족수준(2.45±.59)은 평균에 미 치지 못하는 것으로 분석되었다. 의원의 특성상 복지에 대한 경영진의 인식이 부족한 점은 현실적 한계라 고 할 수 있다. 복지에 대한 의원방사선사의 만족수준을 높이기 위해서는 의원을 경영하는 의료진의 인식 의 전환과 함께 전향적인 변화가 있어야 할 것으로 판단되며, 복지에 대한 직원들의 욕구조사를 통한 효과 적인 선택적 복지를 제공하는 것이 중요하다고 볼 수 있다.

Suspended and sinking particles were collected during ODP Leg 119 to the Indian Ocean sector of the Antarctic Ocean. Field work was carried out at four sampling sites in Prydz Bay. Two of these sites were located in the Outer Bay, and two in the Inner Bay. At the four locations, a total of ten deployments of a sediment trap array were made. The concentrations of carotenoids both in suspended and sinking particulate matter in Prydz Bay were analyzed using HPLC. Fucoxanthin was the dominant carotenoid pigments both in suspended and sinking particles. The present study also indicates that 19'-hexanoyoxyfucoxanthin-containing prymesiophytes (Phaeocystis spp.) was abundant in the study area. The flux rates of carotenoids were generally highest at 50 m, and approximately double the flux rates at deeper horizons, however, at Inner Bay sites, the mean flux rates of carotenoids were greatest at 200 m, and 3 times greater than that of 50 m. Such anomalous high fluxes at 200 m imply that grazers were locally abundant between 100 m and 200 m at these sites close to land, and this hypothesis is supported by visual evidence of lots of fecal pellets in the 200 m trap. Integrates standing stocks versus sinking pigments data support that particulate material in Prydz Bay was not recycled rapidly.

We investigated the effects of temperature changes on the oxygen consumption rhythm in Japanese eels, Anguilla japonica, using an automatic intermittent flow respirometer (AIFR). The endogenous rhythm of the oxygen consumption rate (OCR) in the eels (n = 18; 44-74 cm, 145-690 g), freshly collected by bag net from estuaries, was nearly synchronous with the tidal pattern of the estuarine collection site. The magnitude of mean OCR (mOCR) of eels showed variable range of 82.2 - 116.5 ml O2 kg-1 ww h-1 under constant conditions. In case of increasing temperature from 25 to 38℃, the OCR of eels exhibited a gradually increasing trend with a rhythmic pattern until 36℃. Above 36℃, the rhythms of the OCR dampened and the OCR decreased rapidly at around 36 - 37℃. The OCR of the eels exhibited the maximum value at 38℃, and then it sharply decreased. The results suggested that the critical thermal maximum (CTM) regarding the endogenous rhythms of the eels was at around 36 - 37℃ when water temperature increased at 0.5℃/14 h following the acclimation at 25℃. In case of decreasing temperature (0.5℃/14 h) from 25 to 0℃, the OCR of the eels displayed a abrupt decrease up to 23℃, and between at 23 and 20℃, there was an agitation which showed a slight increase in the OCR with a duration of 1-2 days. Below 9℃, the OCR rhythm of the eels showed a constant state regardless of temperature decreasing. These results suggest that the Japanese eel has an upper incipient lethal temperature at 36℃, with a lower thermal limit at 9℃. The biochemical aspects of the eels influenced by water temperature need to be further studied.

Suspended and sinking particles were collected in austral summer during ODP Leg 119 to the Indian Ocean sector of the Antarctic Ocean. Field work was carried out at four sampling sites in Prydz Bay. Two of these sites were located in the Outer Bay, and two in the Inner Bay. At the four locations, a total of ten deployments of a sediment trap array were made. The concentrations of chlorophylls and their degradation products both in suspended and sinking particulate matter in Prydz Bay were analyzed using HPLC. Chlorophylls a and c were the dominant algal pigments both in suspended and sinking particles. Because of the abundance of fecal pellets at Site 740, the mean fluxes at 200 m averaged 6 fold greater than that at 50 m. This implies that a dense swarm of zooplankters, presumably large copepods and/or salps, may "feed and excrete" mainly in between 100-200 m depths at this site, closest to land in Prydz Bay. Interestingly, The flux of phaeophorbide a was generally similar in magnitude to that of chlorophyll a throughout the study areas. This is an evidence that materials escaping from near-surface regions in austral summer derive mainly from the gazing of zooplankters. "New production" from sediment-trapped CHL pigment fluxes in Prydz Bay was estimated using f-ratio of 0.15, ranging from 520 to 1,605 μgC m-2 day-1.

The effects of the cation-to-anion resin ratio and bed depth on ion exchange performance of mixed-bed were studied at ultralow solution concentration. Breakthrough curves were experimentally obtained for NaCl solution as functions of resin ratio and bed depth. The bed depth affects the pattern of the sodium breakthrough curve but not the chloride breakthrough curve in beds because of the selectivity difference. Resin selectivity determines the shape of breakthrough curves. Some sodium and chloride breakthrough curves crossed at a point as a function of resin ratio. The lower cation-to-anion resin ratio showed the higher effluent concentration or treated volume of the crossover point regardless of the total resin weight.

The natural pigment Cyanidin-3-glucoside (C3G) content of rice bran was analyzed with different polishing degrees in pigment layer of Heugjinjubyeo produced at National Crop Experiment Station in 1999. The general composition of rice bran of Heugjinjubyeo

Photosynthetic pigments and their degradation products in suspended and sinking particles collected from the Gulf of Mexico waters 1987∼88, were measured using High Performance Liquid Chromatography (HPLC). The short term variations in flux rates of chlorophylls and carotenoids as well as their degradation products were compared at the mesoscale cyclonic and anticyclonic circulation features (cold core ring and warm core ring). Chlorophyll a was the predominant porphyrin of suspended particulate matter at both CCR and WCR. Among carotenoid pigments, 19`-hexanoyloxyfucoxanthin, which is a biomarker of prymnesiophytes, was dominant pigment at both rings. Phaeophorbide a, which is produced through the grazing processes of grazers, was the predominant degraded pigment in sinking particles at the study area. Total pigment flux in CCR was an order of magnitude higher than that in WCR. Less than 1% of the standing stock of the pigments measured sank out of the upper 200 m of the WCR on any given day. Thus, suspended particulate matter in Gulf of Mexico was not recycled rapidly.
