목적 : 산업장 근무 근로자들에 있어서 소음 노출이 혈압과 심박동수에 미치는 영향을 조사하고자 하였다. 방법 : 부산시 소재 한 주물공장 근무 근로자로서 소음 작업장에 근무하는 102명에 대하여 1998년 3-6월, 1999년 3-6월에 걸쳐 안정시 혈압과 청력손실정도, 일반적 특성이 조사되었다. 소음노출 정도는 noise dosimeter를 사용하여 오전 8시-오후 4시까지 8시간동안 측정하여 평가하였고, 활동 중 혈압과 심박동수는 ambulatory blood pressure로 오전 8 시-오후 10시까지 30분 단위로 측정하였다. 결과 : 연령과 흡연, 신체비만지수의 영향을 고려하였을 때 저연령층에서 85dBA이상의 고소음에 노출된 군에서 소음과 수축기 혈압간에는 유의한 양의 상관관계가 있었으나, 이완기 혈압과 심박등수에서는 유의한 결과를 얻지 못하였다. 연령의 구분없이 상관관계를 구하였을 때에는 수축기 혈압에서만 소음수준과 유의한 상관성이 있었다. 오전 8시-오후 10시까지 측정한 활동 중 혈압과 심박동수의 일일 변화는 40세미만의 저연령층에서는 심박동수에서만 근무후의 오후시간부터 감소하는 양상이 있었고 수축기 혈압과 이완기 혈압에서는 뚜렷한 변화를 발견할 수 없었다. 40세이상군에서는 수축기혈압과 이완기 혈압, 심박동수 모두 근무 중에는 비교적 높은 값을 유지하다가 오후부터는 감소하는 추세를 보이고 있었다. 각 연령군별 소음노출수준에 따른 활동 중 혈압과 심박동수의 비교에서는 40세미만의 연령층에서만 85dBA이상의 고소음군에서 심박동수가 유의하게 더 높은 결과를 얻었다. 결론 : 저연령층인 40세피만에서 85dBA이상의 고소음에 지속적으로 노출될 경우 수축기 혈압이 증가되어 있을 수 있음을 확인하였다. Objectives : This study was carriel out to evaluate the effects of Industrial noise on blood pressure and heart rate. Methods Resting blood pressure, hearing loss, and general characteristics of the 102 subjects who were engaged In a factory in Pusan were measured from March to June for two years, in 1998 and 1999. With noise dosimeter, noise exposure level was measured from 8 A.M. to 4 P.M. Ambulatory blood pressure and heart rate were also measured every 30 minutes from 8 A. M. to 10 p. M. Results : Controlling for age, smoking, and Quetelet's index, in subjects of under 40 years old exposed to higher than 85dBA, noise exposure and systolic blood pressure had astatistically significant correlation, and the same result was obtained in all subjects. The daily variability of ambulatory blood pressure and heart rate were observed in older than 40 years old group, but only heal·t rate in under 40 years old. Conclusions : The blood pressure and heart 1·ate would be elevated when the workers exposed to noise. And in under 40 years old, the systolic blood pressure was elevated to the workers exposed to higher than 85dBA.

This study is to reveal problems of forest development, present environmental ethics against various activities disturbing forest ecosystems, and provide fundamental view for sustainable developmental policies of forest in Korea. In forest conversion to other uses in Korea, one-agricultural sectors are occupying large proportions, and the tendency of unsustainable development is appearing. Sustainability in the forestry sector is divided into that of forest resources and forest ecosystems, and, thus, how to introduce development methods that support the original forms of forest ecosystems and bring up as economic forest is linked to the future of forest in Korea. Golf courses and ski resorts are considered as ‘wrong’from the ethical view of the land ethics by Aldo Leopold because they do not contribute to integrity, security, beauty of biotic community of forest, and, thus, foresters need to express the clear standpoint and attitude against them. Reforestation in forested area is discrepant from the principles of land ethics and economic loic, forest plantation are presented as an alternative plan for maintaining of sustainability of forest plantation are presented as an alternative plan for maintaining of sustainability of forest resources. Foresters cannot pose a problem to livestock industry unless it converts forests to pastures, but views of animal liberation and animal right have ethical validity, and vegetarianism as personal ethics of forester has practical meanings of environmental preservation as we consider impacts of livestock industry on forest ecosystems. View of the animal right against hunting and poaching has ethically persuasive power than that of ecocentricism. With considering the present situation of forest ecosystem in our country, preclusion of poaching and illegal gathering rather than promotion of hunting accords with forester’s proper task. Approach to forest development should vary with main conditions of forest ecosystems. Strictly regulation for managing developmental projects that cause large­scale physical transformation and deny ontological value of forest are ot breaking the principles of free market economy, but are restoring a justice ethically for sustainable development.

Pleomorphic adenoma of the palate is the most common of all intraoral salivary tumors. It can occur at any age but it presents most commonly in the 40∼60 age group, and there is no significant sex preponderance. It grows slowly and is usually painless, firm, well-circumscribed nodule. Because of high rate of recurrence, extra-capsular excision including the overlying mucosa and margin of normal tissue is recommended. We report 10 cases of palatal pelomorphic adenoma which have been successfully treated by extra-capsular excision. The surgical defects smaller than 3㎝ in diameter were covered with palatal acrylic splint for the secondary healing. The larger defects were repaired using palatal island flap in 3 cases, rotation flap and buccal fat graft in each 1 case. No patient showed any recurrence or malignant change during the mean follow-up period of 4 years and 9 months. These repair methods seem to be simple, reliable and uncomplicated procedures in the palatal surgical defects.

Insulinoma is characterized by fasting hypoglycemia, various neuropsychiatric symptoms, and those caused by secondary to hypoglycemia. A 21-year-old female was admitted due to frequent loss of consciousness and dull mentality for a year and three months. She was diagnosed as insulinoma on the basis of Whipple's triad, celiac, and mesenteric angiography, abdominal C.T, scan, and the inappropriately elevat level of the insulin and C-peptide in the serum. When we transferred her to the Department of General Surgery for the remaval of insulinoma, a large mass was revealed in the pancreatic head portion with the invasion of the adjucent structures. Thus they performed Whipple's operation. Histologic examinations by light and electron microscopy showed islet cell tumor and many secretary granules in the cytoplasm. A brief review of the literature was made.

The incidence of metastatic uterine choriocarcinoma to the bowel is rare. In general, trophoblastic tumors are highly vascular tumors, metastatic tumors are often hemorrhagic. Metastatic choriocarcinoma to the jejunum is characteized by highly vascular tumor, and superior mesenteric artery angiography demonstrated a hypervascular tumor stain at the terminal branch of the jujunal artery. However, lower intestinal bleeding as a first manifestation of metastatic choriocarcinoma to the jejunum is very rare. We experienced a case of the metastatic choriocarcinoma of jejunum with metastasis to the lung and liver that occurred after hysterectomy of the hydatidiform mole. The patient had suffered from massive lower intestinal bleeding. After the arteriography, resection of tumor and jejunojejunostomy was performed.
