An Environmental and santiary survey was carried out on 585 houses and 36 wells in Gunseo Area, Okcheon-Gun, Choongbook Province. As a survey on sanitary environments of houses, number of rooms they were using, artificial lightening method, house heating method and sanitary measures in the kitchen were checked. Sanitary environments of drinking water sources were also investigated. Other tested items with water samples were hardness, pH, and chloride ion, and the results were summarized as follows: 1. 38.1 % of all subjected households were using 2 rooms and 29.4%, 3 rooms. 97.0% of all households were lightening their houses with oil lantern and those who were using elec tric lights were 1.7%. Those who were using coal briquett for their house heating were 12 households (2.0%). 7.4% of all households did not have any cupboard in their kitchens and those who were using dry wiping cloth were only 30.3% among all subjected housholds. 2. Main drinking water source was well (78.3%) and the pump was next (15.0%). 33.3% of all drinking water sources were beeing used by more than 6 househods. 96.1% of all drinking sourees (except pumps) were not covered and the drainage was bad in 30.0% of all drinking sources. 3. 47.0% of all households were disposing sewage unsanitarily and most of the rubbishes (93.2%) were beeing used for a compost. 4. 1% of the households were throw them away around their houses. Excrements were beeing used for fertilizer among 97.9% of all households. 4. The average hardness of 36 sampled well water was 188 ppm and the hardness of 7 samples(19.5 %) were over 300 ppm. 5. The average pH of 36 well surveyed were 6.48. Two samples were below 5.5 and 4 were over 7.1. 6. The average chloride ion of all samples were 75.2 ppm. The chloide ion of 4 samples were over 150 pPm, the international standard for drinking water.

In order to obtain an useful information for health management and biological monitoring of lead exposed workers, Authors tried to investigate air lead level and the lead exposed level of workers in lead industry according to occupational category. The subjects in our study were 2074 workers in 7 lead-using industries, and study subjects were divided into 4 occupational categories such as storage battery industry (type 1), primary smelting industry (type 2), secondary smelting industry (type 3) and litharge making industry (type 4). Blood zincprotoporphyrin concentration (ZPP), blood lead concentration (PbB) and urinary δ -aminolevulinic acid (ALAU), hemoglobin (Hb), hematocrit (Hct) were selected as the indices of lead exposure. Personal variables such as age, work duration were also collected. The results were as follows. 1. The geometric mean air lead in 9 lead-using industry was 0.1133±4.3120 ㎎/㎥, and that in type 1, 2, 3 and 4 was 0.1038±3.4952 ㎎/㎥, 0.0429±3.4329 ㎎/㎥, 0.1877±2.5123 ㎎/㎥ and 0.9961±5.2910 ㎎/㎥, respectively. 2. The mean ZPP in 9 lead-using industry was 53.1±28.0 ㎍/㎗, and that in type 1, 2, 3 and 4 was 52.0±24.8 ㎍/㎗, 48.0±16.4 ㎍/㎗, 109.8±85.6 ㎍/㎗ and 74.3±37.8 ㎍/㎗, respectively. There was significant difference in ZPP according to occupational category (P<0.01). The percents of lead workers whose ZPP were above 100 ㎍/㎗ in type 1, 2, 3 and 4 were 4.0%, 1.7%, 34.3% and 21.6%, respectively. 3. The mean PbB in lead-using industry was 26.0±11.2 ㎍/㎗, and that in type 1, 2, 3 and 4 was 25.3±11.1 ㎍/㎗, 26.7±8.8 ㎍/㎗, 50.3±15.2 ㎍/㎗ and 36.4±11.0 ㎍/㎗, respectively. There was significant difference in PbB according to occupational category (P<0.01). The percents of lead workers whose PbB were above 40 ㎍/㎗ in type 1, 2, 3 and 4 were 10.4%, 7.7% 71.9% and 43.2%, respectively. 4. While the correlation of Hb corrected PbB with ZPP was higher than non corrected PbB, the correlation of log-transformed ZPP with PbB was higher than non corrected ZPP. 5. Simple linear regressions of PbB and corrected PbB as independent variable with ZPP, log-transformed ZPP and ALAU as dependent variable were statistically significant (P0.01). Coefficient of determination of corrected PbB with other variables was higher than non corrected PbB. As the result of this study, it was suggested that reconsideration of environmental and biological monitoring program was highly recommended for secondary smelting and litharge making industry.

Use of amplitude-integrated electroencephalography in decision-making for extracorporeal membrane oxygenation in comatose cardiac arrest patients whose eventual neurologic recovery is uncertain

이병국,정경운,이동훈,조용수,정용훈 대한응급의학회 2019 Clinical and Experimental Emergency Medicine Vol.6 No.4

Comatose cardiac arrest patients frequently experience cardiogenic shock or recurrent arrest. Extracorporeal membrane oxygenation (ECMO) can be used to salvage patients with cardiogenic shock or cardiac arrest refractory to conventional therapies. However, in comatose cardiac arrest patients whose neurologic recovery is uncertain, the use of ECMO is restricted because it requires considerable financial and human resources. Amplitude-integrated electroencephalography is an easily applicable, real-time electroencephalography monitoring tool that has been increasingly used to monitor brain activity in comatose cardiac arrest patients. We describe our experience of using amplitude-integrated electroencephalography in decision-making to place ECMO for comatose cardiac arrest patients whose eventual neurologic recovery appeared uncertain at the time of ECMO placement.

Purpose: Hyponatremia is the most common electrolyte imbalance encountered in the hospital, there have been few studies about the clinical characteristics of hyponatremia in emergency patients. This study was performed to evaluate the causes and the initial symptoms of hyponatremia in emergency patients, the relationship between their ages and their initial symptoms and the relationship between the causes and the recovery time. Methods: A total of 42 patients with hyponatremia, who were treated in the Emergency Department of Chonnam National University Hospital from 2000 to 2001, were studied by chart review. Results: The initial symptoms were generalized weakness (33.3%), seizure (28.6%), mental change (21.6%), confusion (9.5%), dizziness (4.8%), and non-specific (2.4%). There was a significant difference in the initial symptoms between children and older. The initial symptom for younger patients was usually seizure. The most common causes of hyponatremia were dehydration and sodium loss (52.4%), other causes were hypothyroidism (11.9%), SIADH (7.1%), heart failure (7.1%), adrenal insufficiency (4.8%), polydypsia (4.8%), CRF (2.4%), nephrotic syndrome (2.4%) and unidentified causes (7.1%). There were significant differences in the recovery times among the causes of hyponatremia. Conclusion: The initial symptoms of hyponatremia in emergency patients were usually generalized weakness in older patients and seizure in the young. There were significant differences in the recovery times among the causes of hyponatremia. There were many more incidences of hypovolemic hyponatremia of emergency patients than normovolemic hyponatremia.

전통이 가치를 재생산할 수 있는 생명력을 의미한다면 우리 충대인이 세우는 전통은 우리 대학 나아가서는 국가전체를 발전 향상시킬 수 있는 원동력이 될 것이다. 전통은 창립할 수가 있다. 낡고 무가치한 구습, 인습을 묵수한다는 것은 전통의 존중이 아니라 전통의 모독일 뿐이다. 우리 대학의 발전을 위해 우리 모두가 충대인이라는 긍지를 가지고 어디에서든 떳떳이 나설 수 있도록 무가치한 구습, 창조력이 결지된 인습에서 하루속히 탈피할 것이며 우리 자신의 결점과 문제점을 찾아 과감히 혁신함으로써 보다 나은 전통을 이루기 위한 질서확립을 모색할 때이다.
