본 연구는 비측량용 사진기를 이용한 근거리 사진측정법을 적용하여 해빈단면을 추정하는 방법을 제시한다. 수평면 위에 고정된 비디오로부터 획득한 경사비디오영상을 해석하는 방법을 기초로 다음 두 가지 관점을 고려하여 경사사진 해석에 적합한 방정식을 유도하였다. (1) 사진기가 광축에 대하여 회전되는 것을 허용하였다. (2) 정확도를 향상시키기 위하여 렌즈왜곡을 비롯한 사진 계통상의 오차를 보정하는 단순한 오차모형을 도입하였다. 수정된 방정식을 검증하기 위하여 1998년 2월에 동해시 해빈에서 사진촬영과 정밀한 수준측량을 수행하였다. 그 결과 근거리 사진측정을 통한 해빈단면 추정값과 실제 측량값 사이의 수직거리에 대한 RMS 오차는 10 cm 이내였다. This study presents a close-range photogrammetry that is applicable to beach profile estimation using a non-metric camera. Based on the analysis of oblique video image in which the video camera was installed on a horizontal plane and the field of view was fixed, a new equation to analyze a photograph was developed considering the following aspects: (1) camera is allowed to be rotated about its optical axis and (2) a simple error model is adopted to correct lens distortion and other systematic errors associated with the non-metric camera, which improves accuracy of non-metric imageries. To test the modified technique, photographs of the beach were taken near the Donghae City in February, 1998. In addition, beach profiles were surveyed with conventional dumpy level and surveying staff. RMS error between the estimated and measured beach profiles is less than 10 cm in elevation.

심아밀로이드증의 궁극적 치료는 아밀로이드 침착의 병인에 달려 있으므로 증상치료와 함께 초기에 아밀로이드증의 원인을 밝히는 것이 무엇보다 중요하다. 강직성 척추염에서 AA형 아밀로이드증이 심장을 침범하는 경우는 흔치 않으며, 특히 본 증례는 동반질환인 MGUS와 연관된 AL형 심아밀로이드증이 심장 조직검사를 통해 함께 진단되어 치료를 시행한 경우로, 이와 같은 예는 국내 보고된 사례가 없어 저자들이 경험한 1예를 문헌고찰과 함께 보고한다. Amyloidosis is a clinical disorder caused by extracellular deposition of proteinaceous insoluble fibrils in various tissues, resulting in organ compromise. Amyloid L (AL) amyloidosis is the most common type of systemic amyloidosis, which occurs in association with multiple myeloma or monoclonal gammopathy of undetermined significance (MGUS). Secondary amyloid A (AA) amyloidosis is a complication of chronic inflammatory conditions, such as rheumatoid arthritis or ankylosing spondylitis. We report a case of a 49-year-old manwith a 11-year history of ankylosing spondylitis, who was recently diagnosed with MGUS presented with cardiac amyloidosis of both the AA and AL types. We report this case along with a review of relevant literature.

Purpose: To understand the essentials of rearing conflict experience by three shift nurses in advanced general hospitals. Methods: The design was a qualitative research of phenomenology. Participants were 7 shift nurses working in advanced general hospitals who were rearing young children. Data were collected individually through in-depth interview on their life experiences. Data were analyzed by Colaizzi’s phenomenological methodology. Results: Eighteen themes were drawn from 256 meaningful experiences and these themes were integrated to six theme clusters. The most influencing themes were ‘Regret that I cannot satisfy even the slightest wish’, ‘Fail to care for kids’, and ‘Mutual feeling to care giver between appreciation and inconvenience’. Other themes were as follows: ‘Body and mind are broken’, ‘The need for a three-shift system to support nurses who are rearing children’, ‘Doing my best for work and child rearing’. Conclusion: The nature of three-shift nurses working in advanced hospital and caring kids is explained as ‘lives with conflict’ between work and home. This study suggests it is necessary to establish a 24-hour care center for 3-shift nurses to keep working while rearing their children.

Ankle-foot orthosis(AFO) with a pneumatic rubber actuator, which is intended for the assistance and the enhancement of ankle muscular activities was developed. In this study, appropriate amount of power pattern of the device and the effectiveness of the system was investigated. The subjects were performed the gait motion with and without the AFO. We made a comparison the muscular activities between with and without the AFO. A Biodex dynamometer was used to measure the maximal concentric strength of the plantar flexors of with and without the orthosis on right side. The experiment results in gait motion showed that the muscular activities wearing the AFO were reduced and the peak torque values wearing it were increased. Therefore, we confirmed the effectiveness of the developed AFO.

국내산 해조류로부터 항혈전 제제의 개발을 위하여 해조류 열수추출물에 대하여 항응고 활성의 검색과정에서 높은 활성을 보였던 톳(Hizikia fusiforme)에서 항응고 활성 다당류를 분리, 정제하고 이 다당류의 화학적 특성과 항응고 활성 기작을 조사하였다. 분리, 정제는 톳(Hizikia fusiforme)의 열수추출물(HF-0)을 ethanol 농도별 침전을 실시한 결과 70% ethanol 온도에서 침전한 HF-2 획분이 가장 활성이 높았다. HF-2를 pronase와 periodate를 이용하여 단백질과 탄수화물을 선택 분해하여 활성을 비교한 결과 활성의 본체는 다당이었다. DEAE-Toyopearl 650C(Cl form)의 이온교환 크로마토그래프를 실시하여 5개의 획분으로 나누었으며 1.0M의 NaCl 농도에서 용출된 HF-2-3 획분이 가장 활성이 높았다. HF-2-3 획분을 Sephadex G-75(HF-2-3-1)와 Sepharose CL-6B(HF-2-3-1a)로 겔여과 크로마토그래피를 실시하여 최종적으로 정제된 다당류 HF-2-3-1a 획분을 얻어 그 순도를 GPC와 HPLC를 이용하여 확인하였다. 정제다당(HF-2-3-1a)의 분자량은 5.3×10^5 Da이었으며 주구성당은 fucose(51.92%), galactose(19.34%), mannose(13.92%), xylose(7.14%), arabinose(3.95%) 및 rhamnose(3.78%) 등으로 정제된 다당은 29.7%의 황산기를 함유하는 함황성 fucoidan이었다. HF-2-3-1a의 항응고 활성은 내인성 경로를 억제하며 fibrin 형성능을 측정한 결과 직접적으로 thrombin에 작용하지는 못하고 antithrombin Ⅲ의 활성을 증폭시켜 항응고 활성을 나타내며 농도 의존성 항응고 활성을 나타내었다. 톳 열수 추출물의 항응고 활성을 in vivo에서 측정한 결과 100㎎/㎏의 농도에서부터 활성이 나타나기 시작하여 250㎎/㎏의 농도에서는 100%의 항응고 활성이 나다났다. This study was focused on the purification, characterization and promotion mode of an anticoagulant polysaccharide from Hizikia fusiforme. The anticoagulant crude polysaccharide(HF-0) was obtained by using hot water extraction at 100℃ for 3 hrs after homogenizing desalted Hizikia fusiforme. The anticoagulant polysaccharide(HF-2-3-1a) was purified from the crude extract(HF-0) through stepwise gradient ethanol precipitation(HF-2), DEAE-Toyopearl 650C(HF-2-3), Sephadex G-75(HF-2-3-1), Sepharose CL-6B(HF-2-3-1a) chromatography and HPLC to homogeneity. HF-2-3-1a was estimated at 5.3×10^5 Da molecular weight and composed of fucose(51.92%), galactose(19.34%), mannose(13.92%), xylose(7.14%), arabinose(3.95%) and rhamnose(3.78%), and comprimised 29.7% sulfate residue. The sulfated anticoagulant polysaccharide from HF-2-3-1a was proposed to inhibit via the intrinsic pathway and common pathway in the blood coagulation. The HF-2-3-1a exhibited the anticoagulant activity by activating an antithrombin Ⅲ and the activity depended on the concentration of HF-2-3-1a. Acute toxicity of HF-2 in mice was not detected. Only 14 of 33 control mice(11.4%) that had taken saline survived for 30 min after injecting thrombin(100 NIH unit/ml).

Purpose: The purpose of this study was to provide data for development of the Journal of Fundamentals of Nursing through reviewing classification of sectional editorship. Method: Descriptive statistical analysis was used, to identify content then, the classifications of sectional editorship were reviewed. Results: The categories, “Basic concepts of nursing” (30.2%:17.9%), “Needs for comfort” (15.9%:13.1%), “Nursing education” (12.7%:12.7%), and “Needs for activity and exercise” (7.1%:7.1%) were most frequent through both the 1st and 2nd sectional editorship. Conclusion: Classification of sectional editorship was developed to clarify the educational purpose of fundamentals of nursing, and was modified through reflections by researchers. The current classification of sectional editorship is not a permanent formula, so using various viewpoints in further examination is needed.
