레이저는 현재 급성장하고 있는 광산업의 주역으로서 광산업의 이해는 레이저 빛의 특성과 레이저 발진원리의 이해 및 응용기술의 이해에 근간을 두어야할 것이다. 따라서 본고는 보다 이론적으로 알기쉽게 레이저빛의 본질적 특성의 원인분석과 레이저의 발진원리를 새로운 관점에서 설명하고 레이저 종류 및 기본 응용기술을 간단히 소개하였다.

사무실 근로자들에게는 일반적으로 광산일이나 건축업과 같이 위험한 작업에 비하여 전형적인 건강장해를 일으킬만한 요인이 없는 것은 사실이다. 그러나 사무실 근로자들에 있어서도 그것이 비록 급성으로 나타나는 치명적인 장해가 아니거나, 매우 위험스러운 것이 아니라 할지라도 단순히 간파해서는 안될 건강 장해의 가능성이 있다. 이는 크게 요통을 포합하는 근육통, 조명, 소음, 공기오염 등으로 대별될 수 있다.

The mechanisms responsible for ischemia/reperfusion (I/R) injury have direct or indirect relevance to clinical lung injury after severe shock, cardiopulmonary bypass, and transplantation. This study investigated the effects of aspirin on intestinal I/R-induced acute lung injury (ALI) in rats. Lipopolysaccharide (LPS) induced cyclooxygenase-2 (COX-2) expression in A549 and RAW264.7 cells. RAW264.7 macrophages had shown greater expression of COX-2 than A549 cells. In addition, the NADPH oxidase inhibitor apocynin and p38 MAPK inhibitor SB203580 attenuated LPS-stimulated COX-2 expression. To induce ALI, intestinal ischemia was performed for 60 min prior to the 4 hr reperfusion by clamping the superior mesenteric artery in Sprague-Dawley rats. In order to test and compare the effect of non-specific COX inhibitor aspirin with the effect of mepacrine, a well known phospholipase$A_{2}$ inhibitor, rats were divided into 4 groups: Sham, I/R, Mepa+I/R (mepacrine, 60 mg/kg, i.p.), ASA+I/R (aspirin, 10 mg/kg, i.p.). In the present investigation, myeloperoxidase activities in the lung and intestinal tissues were increased by I/R. These changes were reduced by single pretreatment of mepacrine (60 mg/kg, i.p.) or aspirin (10 mg/kg, i.p.) 30 min before I/R. Structural studies demonstrated that the tissue injuries in the lung and intestine after I/R were also attenuated by the pretreatment of mepacrine or aspirin. These results suggest that I/R-induced ALI is mediated, in part, by the activation of COX. In addition, pretreatment of aspirin might be helpful for the prevention of ALI in ARDS-prone patients. In addition, the p38 MAPK inhibitor and apocynin also might be helpful to ALI through the inhibition of COX-2 expression.

Nonocclusive mesenteric ischemia (NOMI) is a rare complication that occurs in about 0.05% of patients after openheart surgery, and NOMI refers to the mesenteric ischemia that's caused by splanchnic vasospasm without occlusion of the great intestinal vessels. In the presently reported case, NOMI developed to maintain the blood flow to the heart and brain after several minutes of a hypotensive status and the latter was caused by acute aortic dissection that complicated an aortic cannulation procedure. Unfortunately, the patient died even though the problems were diagnosed early and proper treatment was administered. Early diagnosis of NOMI by angiography and the selective infusion of vasodilators are thought to be the only way to improve survival for patients with clinically suspected NOMI.

본 연구는 산업 간호사의 통상증상에 대한 투약 및 처치, 타의료기관에 의뢰내용, 응급조치 내용을 업종별로 비교 분석코저 한다. 연구방법은 산업간호사회에 등록된 산업장 중 서울, 인천, 마산, 창원, 부산, 울산지역에 있는 130개 산업장에 근무하는 산업간호사를 대상으로 설문조사하였다. 연구결과는 다음과 같다. 1) 신체기관별 통상증상에 대한 처치 및 투약은 서비스업과 제조업, 기타제조업 모두에서 소화기계, 호흡기계증상에 대한 처치 및 투약 업무가 가장 많았으며 업종별로 보면 서비스업의 경우 소화불량, 감기, 근육통, 설사, 기침, 두통, 복통, 구토, 변비 등이 80% 이상을 차지하였다. 제조업의 경우 소화불량, 감기, 설사, 두통, 근육통 등이 많았으며 기타제조업의 경우 감기, 두통, 소화불량, 근육통, 설사, 기침, 눈다락지 순으로 나타났다. 2) 근로자를 타의료기관에 의뢰 하는 내용은 즉각적인 수술을 요할때나 골절, 내부장기의 손상, 두뇌손상, 출혈 등으로 나타났다. 3) 업종별 응급조치내용은 서비스업에서는 화상과 쇼크, 출혈이 가장 많았으며 유해물질의 급성중독의 경우가 가장 적었다. 제조업에서는 화상, 골절, 쇼크, 출혈, 유해물질의 급성중독이, 기타제조업에서는 화상, 골절, 쇼크, 출혈의 순으로 많았다. 4) 업종별 구비관리하고 있는 의약품은 서비스업종이 제조업, 기타제조업보다 많은 의약품을 구비하고 있었으나 경미한 통상증상에 대한 의약품으로 나타났다. 이러한 연구결과들을 통해 볼때 제조업, 기타제조업, 서비스업종의 보건관리자가 일차보건의료수준에서의 투약 및 처치를 시행하고 있는 바, 이에 대한 구체적이고 명확한 투약의 범위를 설정하여 보건관리자의 직무를 표준화할 필요가 있으며 서비스업종에 종사하는 근로자의 건강문제와 관련요인을 구체적으로 연구할 것을 제안한다.

Alkaline reduced water (ARW) has been used for drinking widely in several countries of Asia. The safety and clinical effects of ARW has been reported including anti-oxidative effect and intestinal abnormal fermentation. To confirm the effect of ARW on DSS-induced acute inflammatory bowel disease (IBD) mouse model, we observed the length of total large intestine and the histopathological changes after supplying mineral induced-ARW (MARW) for 2 weeks and oral administration of 4% DSS (dextran sulfate sodium). As the result, the length of total large intestine and the disease scores by macro and microscopical access in the ARWsupplied group showed no significant differences compared with those in the control group. This result suggests that the supply of ARW for 2 weeks exerted no effect on amelioration in the DSS-induced acute IBD model. However, in consideration of the effect of ARW on the improvement of intestinal environment and gastrointestinal disease, this result seems that acute IBD animal model is not suitable or the period of ARW supply is not enough to prove the effect of ARW. The ameliorative effect of ARW on the intestinal abnormal fermentation has been confirmed by some researchers, but the precise mechanism also remain unclear. In conclusion, although MARW had no effect on the DSS-induced acute experimental colitis model, further studies on the verification of the effects of ARW by using other intestinal disease model and by long-term supply of ARW will be required. Also, It needs to clear the mechanism of ARW on the intestinal environment.

Duplication cysts are rare congenital malformations, that may be detected anywhere along the alimentary tract, and they may communicate with the intestinal tract. Cystic duplication of the cecum is especially rare. About 80% of these cases are detected in the first 2 years of life as a result of an acute intestinal obstruction, which manifests as vomiting, recurrent abdominal pain, recurrent gastrointestinal bleeding and constipation. We report a case of intestinal obstruction secondary to a duplication cyst of the cecum in a neonate. The patient underwent surgery and was diagnosed subsequently, and is presently healthy.

The hamstring muscle injury is a quite common sports injury which has a wide spectrum of treatment option that simple muscle strain can be treated conservatively otherwise total rupture of muscle or musculotendinous junction must be treated surgically. Among them, rupture of proximal hamstring muscle near at its origin site is quite uncommon and it should be treated surgically because it could cause several complications if not treated appropriately. In this case report, the authors report successful surgical treatment of acute rupture of proximal hamstring muscle and also would like to review the clinical presentation of this type of injury.

Among the late postoperative complications of the acute dissection of aorta, the fistula between dilated distal aorta and pulmonary parenchym is so rare that only few case have been reported sporadically. Although the aortopulmonary fistula is one of a fatal condition that needs prompt surgical intervention, with an appropriate management it is well controllable condition. Early diagnosis and urgent surgical intervention is the only way to prevent catastrophic hemorrhage. We experienced a surgical management of aortoplumonary fistula which occurred between upper lobe of the left lung and distal aortic dilatation of previous aortic bypass graft which was performed for Debakey type I acute aortic dissection.
