The study was conducted to evaluate the difference of life style, subjective symptoms and health cognition depending on the Sasang Constitution in the industrial workers. The results were as follows ; Constitutional distribution among exposed group were Tae-eum In(38.4%), So-eum In(35.2%), and So-yang In(26.4%) and it was turned out that Tae-eum In took a higher portion of Sasang constitution than other constitutions in technician workers. 'Exercise' and 'Obesity' were found most in Tae-eum In, In So-eum In there were many 'Normal' weight and 'Having digestive disorders' were found most in So-eum In. There were no significant difference in the health cognition among the constitutions. The closer to 'normal' weight, the higher prevalence in 'having' concern about health condition and the more 'normal' condition in sleeping, the higher prevalence of 'having' self-confident in present health.

Demand of micro holes has been increased fast, especially in the area of inkjet nozzle, micro turbine and optical parts. However, the micro hole with 40㎛ exit diameter and aspect ratio of 10 has yet to be reported. In this study, an endeavor was made to manufacture the micro hole under over 40㎛ exit diameter at stainless steel plate with 40㎛ thickness. To accomplish the goal, the relationship between machining parameters and machined result was identified. It was found that the entrance clearance was proportional to the discharge power, when discharge energy was kept constant and resistance had to be as high as possible at the given condition to minimize the machining time. 40㎛ average diameter of the micro hole with over 10 aspect ratio was achieved under the condition of 60V, 680pF, 500Ω, 1.5㎛ and 1500rpm.

Epstein-Barr virus(EBV) is known to be related to a nasopharyngeal lymphoepithelioma(LE) and undifferentiated carcinoma with intense lymphoid stroma(UCLS) of the stomach, which is histologically identical with LE. In this study, the prevalence of EBV infection in UCLS of the stomach was investigated by EBV-encoded RNAs(EBERs) in situ hybridization block applied to formalin-fixed, paraffinembedded sections from 12 gastric UCLS. These cases were collected during 8 years' period from 1986 to 1993 in Hanyang University Hospital. EBERs were present in 10 cases of 12 UCLS(83%), a similar proportion that has been observed in a Japanese series. The EBER positive signals were characterized by the presence of uniform hybridized grains in almost all carcinoma cells and by their absence from adjacent non-neoplastic epithelial cells and lymphoid cells of the stroma. In view of oncogenetic role, significance of EBV infection in UCLS cells was discussed.

The purpose of this study was l)to quantitatively observe changes in both static and dynamic balance performance, 2)to establish appropriate testing and treatment protocol. Subjects consisted of 39 mens(mean age 24.84 years) and 36 womans(mean age 22.66 years) without musculoskeletal or neurological impairments. Postural sway characteristic were examined using dynamic balance sysem. Each trial was 30 sec in duration. Center of balance, a vertical force measurement and sway index was evaluated under each of 6 conditions;2 visual conditions(eye open, eye closed), 3 platform conditions(stable, linear toes up/down). An effect was found for average diplacement to the left along the X axis under all testing conditions. Postural sway was greater toes up/down than linear platform condition. In this study, the data developed could be appropriate to use for some comparisons when evaluating patients with neurologic impairment and other age range.

Fat embolism is the presence of fat globules in the peripheral circutation and in the lung, brain, kidney, pearl, and so on -not in the fine emulsion of a metabolic lipemia but in globules large enough to obstruct arterioles and capillaries. The fat droplets can deride from fractures of long bone due to disruption of the fatty marrow from extensive bruising of the soft tissue, and from fat tissue in burns. Fat embolism has also been reported in patients suffering from various diseases including alcoholism, fatty liver, diabetes mellitus and pancreatitis. We investigated 19 autopsies with fatty liver of varying degrees to establish a correlation between fatty change of limier and pulmonary fat embolism. Among 19 cases, 3 cases with moderate to severe fatty change of elver, and 1 case with submassive hepatic necrosis and mild fatty change showed Grade II pulmonary fat embolism. In histologic section with Sudan III stain, the arteries and capillaries of lung were occupied and distended by round, oval, or staghorn fat globules. The alveoli may contain edema fluid and blood Although the pulmonary fat embolism occuring in the presented cases didn't cause death on its own, one should be aware that a life-threatening mobilization of fat into the lungs and ever into the systemic circulation is possible In fatty fiver and submassive hepatic necrosis.

위암발증의 원인을 밝히기 위하여 설문조사를 통하여 강원도 화천군에 거주하는 주민들의 일반사항, 생활습관 및 영양섭취실태와, ELISA법으로 Helicobacter pylori 감염률을 조사하였다. 조사 대상자는 40∼69세까지의 지역주민 169명으로 남자 79명, 여자 90명이었으며 그 결과는 다음과 같다. 조사 대상자의 학력은 65.7%가 초등학교 이하였으며, 월수입은 60%가 50만원 이하였다. 대상자의 62.7%가 농업에 종사하였고 자녀수는 64.3%가 3∼5명이었으며 대상자의 34.5%가 흡연을 하고 있었고 68.4%가 음주를 한다고 대답하였다. 대상자의 전체 평균신장은 156.7㎝로 여자는 150.1㎝, 남자는 164.4㎝ 이었다. 평균체중은 61.1㎏으로 여자의 체중은 57㎏, 남자는 65.7㎏이었으며 BMI는 전체 평균 25.5%로 여자는 24.8%, 남자는 20.1%이었다. Helicobacter pylori의 감염률은 전체 조사대상자의 66.3%이었으며, 여자의 67.7%, 남자의 64.6%가 감염되었고 연령별로는 40대의 70%, 50대의 62.2%, 60대의 69.4%가 각각 감염된 것으로 나타났다. 일상 생활 요인에 따른 Helicobacter pylori의 감염률은 흡연의 정도가 심하고 학력이 낮으며 월수입이 낮을수록 높은 경향을 보였다. Helicobacter pylori의 감염여부에 따라 감염자와 비감염자의 영양섭취량을 조사해 본 결과 비감염자는 감염자와 비교해서 에너지, 총단백질, 동물성 단백질, 칼슘, 비타민 C 섭취량이 높은 경향을 보였으며 철분과 niacin의 섭취량은 낮은 경향을 보였다. To examine the relationship between the casual infection of gastric cancer and lifestyle and nutritional status, we surveyed 169 persons, 90 females and 79 males, aged 40∼69 years from June 7 to June 14, 1997, in Whachon area, Kang-Won Do, Korea. For this purpose, we investigated Helicobacter pylori infection and identified the effect of sex, age, smoking, alcohol consumption, economic status, occupation, life-style and food intake on Helicobacter pylori infection. Helicobacter pylori status was evaluated using an enzyme-linked immunosorbant assay(ELISA) for anti-Helicobacter pylori immunoglobulin G(IgG). Helicobacter pylori infection was present in 66.3% of total subjects, namely, 67.7% of female and 64.6% of male and its prevalence increased with smoking, low education level and low monthly income. Energy, total protein, calcium and vitamin C intakes in the negative Helicobacter pylori infection group were higher than those in positive Helicobacter pylori infection group. However iron and niacin intakes were lower in the Helicobacter pylori negative group than in the positive group.

합성옥신물질 5,6-Cl_(2)-IAA에 의한 사철나무와 주목 녹지삽수의 발근촉진

The promotive effect of rooting with a newly developed synthetic auxin, 5, 6-dichloro-indole acetic acid (5, 6-Cl_(2)-IAA), was investigated with softwood cuttings of Euonymus japonicus Thunb, and Taxus cuspdata Sieb. et Zucc. Dipping the basal end of cuttings in 5, 6-Cl_2-IAA solutions of different concentrations enhanced the rooting of Euonymus japonicus cuttings in sand medium under mist propagation bench. Treatment of 100 ppm 56-Cl_2-IAA was more effective than IBA treatment at the same concentration. In Tuxus cuspidata,, significant rooting promotion was obtained with 10- 100 ppm basal dippings in solutions of both 5, 6-Cl_(2)-IAA and IBA. However, the root elongation appeared to be promoted by low concentrations of 5,6-CL-IAA as compared to that of IBA treated cuttings.

본 연구는 부산지역의 주요기업 변화를 살펴보기 위해 매출액 기준 전국 상위 1,000대 기업에 속하는 부산기업을 조사하여 비교분석을 실시하였다. 분석결과 2005년에 전국 1,000대 기업 중 46개 기업이 부산에 소재하였는데, 2019년에는 12 개가 줄어든 34개 기업만이 전국 1,000대 기업에 포함되었다. 또한, 전국 상위 1,000대 기업의 매출액 기준으로 부산지역 기업의 매출액 비중은 2005년 1.6%에서 2019년 1.4%로 줄어든 것으 로 나타났다. 이는 수도권 집중현상이 점차 강화되고 있기 때문이다. 한편, 부산지역 매출액 기준 상위 10대 기업은 많은 변화가 있었는데, 2005년 상위 10대 기업 중 2019년에도 상위 10대 기 업에 포함된 기업은 ㈜한진중공업, 르노삼성자동차(주), ㈜부산은행, ㈜서원유통 등 4개뿐인 것 으로 나타났다. 통계적 인과 관계는 확정할 수 없으나 지역 대기업의 쇠퇴 및 유출과 지역의 쇠퇴가 동시에 이루어지고 있어 지역 경제의 침체와 대기업의 쇠퇴 및 유출이 상당한 관계가 있음을 유추해 볼 수 있다. 특히 2011년 이후 지역 주력 제조업 기업들이 1000대 기업 진입에 실패하였다는 점을 주목해 볼 필요가 있다. 지역 제조업 대기업의 이탈 또는 쇠퇴는 지역 생산성 하락에 영향을 미 쳤을 가능성이 높고, 낮아진 지역 산업 생산성이 지역 경제성장률 둔화에도 영향을 미칠 가능성 이 있다. 따라서 지역의 경제활력 저하 문제를 제고하기 위해서는 지역 산업구조 개편 문제와 생 산성 향상 방안에 대한 고민이 필요하다.
