Purpose: This study was to develop and to evaluate a health diary program for solitary elderly. Methods: The research design was a nonequivalent control group pretest-posttest design. There were 30 subjects the experimental group and 54 in the control group among solitary elderly over age 65. The independent variable was the health diary program, and the dependent variables were perceived health status, ADL, IADL, Blood pressure, blood sugar, quality of life, self efficacy and health promoting behaviors. The health diary program was performed for 50minutes, twice a week for 8 weeks. Data was collected from April 3 to June 23, 2006. Results: The experimental group showed a significant difference in perceived health status, blood sugar, ADL, IADL, quality of life, self efficacy, and health promotion behaviors than the control group. There were no significant differences in systolic & diastolic blood pressure. Conclusion: A health diary program showed good effects on improving health status, quality of life, self efficacy, and health promotion behaviors. Therefore, we recommend this program be utilized as a health promoting program for the solitary elderly in the community.

Neurofibroma may present as a solitary lesion or as multiple lesions. Although there is no site of predilection for solitary lesions, occurrence on the hand is rare. Plexiform neurofibroma can develop in isolation or more commonly as a part of neurofibromatosis type 1. In those that apper in isolation, trauma has been suggested as a precipitating factor. A 68-year-old male farmer had experienced repetitive prior episodes of trauma in the involved finger. He presented with a painless mass on the dorsal aspect of the fifth finger. Physical examination showed a protruding mass measuring approximately $15{\times}20mm$ which was not tenderness to palpation and any skin changes or pigmentation. Ultrasonography showed a cystic mass on the dorsal aspect of the middle phalanx. Microsurgical dissection was applied in order to seperated the lesion from the ulnar side of the dorsal branch of the digital nerve. Pathologic examination of the specimens revealed neurofibroma. At three-month follow-up, motor and sensory function were intact, and range of motion was fully recovered. Traumatic solitary neurofibroma is a rare tumor of the hand, especially in the finger. Hand surgeons should be aware of the diagnostic possibilities of this tumor based on examination, history taking and imaging studies.

흉막에 발생한 고릴성 섬유종은 비교적 회귀한 질환으로 알려져 있으며, 대부분 장측 흉막에서 발생하고 벽측 홍막에서 발생되는 경우는 매우 드물다. 저자들은 48세 여자환자에서 우흉곽내 벽측 흉막에서 발생한 거대 고립성 섬유종 1례를 수술 치험하였다. 환자는 10개월전 부터 발생한 호흡곤란이 주증상이었고, 술전 흉부전산화 단층될영상 우측 폐실질을 주변으로 밀어내는 이종의 종괴형태를 보였다. 수술 소견상 종괴는 피낭에 싸여 있었고, 벽측 흉막에서 기 시하였다. 절제된 종괴의 크기는 20cmX15cmX11cm였고, 무게는 2200gm에 이르렀다. 환자는 합병증없이 퇴원하였으며 술후 6개월 간 추적 관찰하였으나 재발의 소견없이 양호한 상태를 보이고 있다.

본 논문에서는 2차원 경계요소법 수치모형을 이용하여 급경사에서 고립파의 처오름과 진행과정을 연구하였다. 먼저 수치모형을 상대적으로 완만한 경사에 적용하여 처오름 높이를 산정하여 기존의 수리모형실험의 결과, 수치해 및 해석해 등과 비교하여 수치모형의 정확도를 검증하였다. 경계요소법에 의한 수치해는 전체적으로 기존의 자료 등과 잘 일치하였다. 다음에 수치모형을 급경사 지형에 적용하여 처오름 높이를 산정한다. 경계요소법은 완경사 뿐만 아니라 급경사에서도 고립파의 최대 처오름 높이 산정에 매우 효율적이며, 경계요소법에 의한 결과는 인공수로의 제방 또는 방파제의 설계에 이용될 수 있을 것이다. 마지막으로, 급경사에서의 고립파의 파고를 계산하여 Green의 법칙에 의한 결과와 비교하였다.

A case of plasmacytoma of the ovary and breast, which developed in a patient with a solitary plasmacytoma in the lumbar vertebra for nine months, was diagnosed cytologically and histologically. Enlargement of the right ovary and multiple palpable masses in the right and left breast were already present at six months after the diagnosis of vertebral solitary plasmacytoma. At eight months, plasma cell leukemia developed, and nine months the enlarged both ovaries, replaced by yellowish-gray solid tumors showed infiltration of immature plasma cells. The cytologic features of the ovarian tumors were same with those of the breast tumor. The tumor cells were of predominantly immature plasma cells with one or more nuclei. Some mature plasma cell had an eccentric nucleus with single nucleolus and peripherally clumped chromatin. Binucleated or multinucleated giant cells were often present. Histologically, sheets of poorly differentiated plasmacytoid tumor cells were separated by strands of hyaline fibrous tissue. On immunohistochemical stains, the tumor cells showed strong reactivity for lambda-light chain but no reaction for kappa-light chain, cytokeratin, or leukocyte common antigen.

Isolated brainstem invlovement of neurocysticercosis is rare. We present the clinical and radiological features of a patient with a solitary cysticercus granuloma in the brainstem confirmed by MRI and CSF ELISA test. Good response was obtained from conservative treatment, using praziquantel. We believe that patients from regions where cysticercosis is endemic, who have no systemic disease, who present with nonprogressive symptoms and signs of brainstem involvement, and display a solitary ring-enhancing mass in the brainstem measuring less than 20mm on neuroimaging may be managed conservatively.

Mastocytosis is a rare disease which occurs in both children and adults, and it can manifest as a solitary or multiple skin lesions. Both can cause cutaneous or systemic symptoms. Because of the heterogeneity of clinical presentation of mastocytosis and its rare prevalence, it can be hard to suspect the mastocytosis at the first time. Most solitary mastocytomas are about 1-5 cm in diameter and have features of brownish-yellow, minimally elevated plaques with a smooth shiny surface. This article presents a case of solitary mastocytoma which occurred in neonate and that we treated through surgical excision. In histopathological examination, it consisted of c-kit-positive mast cells. Although pediatric cutaneous mastocytosis might regress spontaneously, clinicians should keep in mind that it could be associated with systemic mastocytosis which involves hematopoietic system.

본 연구는 고립파를 이용하여 수중에 설치된 연직구조물에 작용하는 지진해일 파력 측정 수리실험을 수행하였다. 다수의 파압계를 이용하여 구조물에 작용하는 파압분포를 측정하였고 측정된 파압분포를 통해 파력을 산출하였다. 측정된 실험결과를 바탕으로 해안구조물 설계에 사용되는 파압예측 경험식과 비교하였고 구조물 단면현상에 따라 파압분포의 차이를 분석하였다. 또한, 구조물 전 후면에서 파고측정을 통해 입사파와 투과파를 비교하였으며 구조물의 형상이 파고변화에 미치는 영향을 분석하였다.

Intestinal tuberculosis is an infection of the gastrointestinal tract by the Mycobacterium tuberculosis complex. To the best of our knowledge, solitary intestinal tuberculosis accompanied by intestinal obstruction, particularly in the middle of the small intestine, is extremely rare. We report a case of solitary jejunal tuberculosis in a 49-year-old man with no underlying disease. He was admitted a few days after the onset of diffuse abdominal discomfort. Upon evaluation, we initially considered a malignancy of the distal jejunum with ileus due to the presence of a mass. Therefore, he underwent laparoscopic resection of the small bowel. Unexpectedly, the histologic specimen showed a chronic caseating granulomatous lesion with acid-fast bacilli. Ultimately, he was diagnosed with solitary jejunal tuberculosis. He was successfully treated with anti-tuberculosis drugs without any complications.

To improve our current understanding of tsunami-like solitary waves interacting with a row of vertical slotted piles on a sloping beach, a 3D numerical wave tank based on the CFD tool $OpenFOAM^{(R)}$ was developed in this study. The Navier-Stokes equations were employed to solve the two-phase incompressible flow, combining with an improved VOF method to track the free surface and a LES model to resolve the turbulence. The numerical model was firstly validated by our laboratory measurements of wave, flow and dynamic pressure around both a row of piles and a single pile on a slope subjected to solitary waves. Subsequently, a series of numerical experiments were conducted to analyze the breaking wave force in view of varying incident wave heights, offshore water depths, spaces between adjacent piles and beach slopes. Finally, a slamming coefficient was discussed to account for the breaking wave force impacting on the piles.
