Purpose: The purpose of this study is to verify the influence of a massive hydrofluoric acid spill on community health through patients who claimed to have been exposed. Methods: We analyzed 2459 patients who visited our emergency department with the claim of exposure to hydrofluoric acid, and retrospective analyses were performed. We analyzed changes in numbers of visitors per day from the day of the accidental hydrofluoric acid spill, symptoms presented by the 1924 patients, and general characteristics. Comparisons of symptoms and hematologic characteristics were made between the initially set evacuation zone(1.3 km radius parameters from the spill) and the outer zone. Results: A total of 2,459 patients who claimed exposure visited our ED from 27 September 2012 to 23 October 2012, and there was a significant increase in the number of visiting patients from day 8 of the hydrofluoric acid spill. The most common complaints were a sore throat, 729(37.9%) and no specific symptom with health concern, 547 (28.4%). Statistically significant findings were pulmonary symptoms (p=0.001), nasal symptoms (p=0.001), diarrhea (p=0.023), and skin symptoms (p=0.007). In hematologic study, a statistically significant difference was observed in white blood cell count (p=0.018), creatine phosphokinase (p<0.001), erythrocyte sediment rate (p=0.013), and phosphorus (p<0.001). Conclusion: A significant increase in the number of patients was observed one week after the accidental spill of hydrofluoric acid. The most frequent symptoms were sore throat, headache, cough, and sputum. Statistically significant increase in creatine phosphokinase level and decrease in phosphorus level were noted in patients within the evacuation zone.

Systematic toxicological analysis (STA) means the process for general unknown screening of drugs and toxic compounds in biological fluids. In order to establish STA, in previous study we investigated pattern of drugs & poisons in autopsy cases during 2007~2009 in Korea, and finally selected 62 drugs as target drugs for STA. In this study, rapid and simple drug identification and quantitative analytical program by gas chromatography-mass spectrometry(GC-MS) was developed. The in-house program, "DrugMan", consisted of modified chemstation data analysis menu and newly developed macro modules. Total 55 drugs among 62 target drugs were applied to this program, they were 14 antidepressants, 8 anti-histamines, 5 sedatives/hypnotics, 5 narcotic analgesics, 3 antipsychotic drugs, and etc. For calibration curves, fifty five drugs were divided into four groups of range considering their therapeutic or toxic concentrations in blood specimen, i.e. 0.05~1 mg/l, 0.1~1 mg/l, 0.1~5 mg/l or 0.5~10 mg/l. Standards spiked bloods were extracted by solid-phase extraction (SPE) with trimipramine-D3 as internal standard. Parameters such as retention times, 3 mass fragment ions, and calibration curves for each drug were registered to DrugMan. A series of identification, semi quantitation of target drugs and reporting the results were performed automatically. Calibration curves for most drugs were linear with correlation coefficients exceeding 0.98. Sensitivity rate of DrugMan was 0.90 (90%) for 55 drugs at the level of 0.5 mg/l. For standard spiked bloods at the level of 0.5 mg/l for 29 drugs, semi quantitative concentrations were ranged 0.36~0.64 mg/l by DrugMan. If more drugs are registered to database in DrugMan in further study, it will be useful tools for STA in forensic toxicology.

임의의 층에서 평면적에 큰 차이를 보이는 3차원 비정형 setback 구조물의 지진 거동 특성과 지진 거동 특성에 미치는 바닥 슬래브의 면내 변형 효과를 연구하였다. 비정형 setback 구조물의 전반적인 지진 거동 특성을 분석하기 위하여 베이스 부분의 평면적과 타워 부분의 평면적의 비(R/sub s/)와 단(setback) 발생 위치(L/sub s/)등을 매개 변수로 사용하였다. 48개의 비정형 setback 구조물들에 대한 해석 결과로부터 정형 구조물과 달리 setback 구조물의 경우에 단(setback) 발생 위치 근방에서 매우 급격한 층 전단력의 변화가 일어남을 알 수 있었다. 바닥슬래브의 면내 변형이 구조물의 지진 거동에 미치는 영향은 횡방향 저항 요소의 배치에 따라 크게 좌우되며 횡방향 저항 요소들간의 강성의 차이가 심하게 나타나는 전단벽-프레임 시스템의 경우에 더욱 두드러지게 나타남을 알 수 있다. 바닥슬래브의 면내 변형은 구조물이 받게 되는 밑면 전단력을 감소시키며 특히 L/sub s/=0.1인 프레임-전단벽 시스템에서 두드러진다. 또한 바닥슬래브의 면내 변형은 전단벽이 설치된 프레임에 대해서는 층 전단력의 감소 효과를 가져오고 전단벽이 설치되지 않은 프레임에 대해서는 층 전단력의 증가 현상을 가져온다. 또한 횡방향 강성의 차이로 발생한 베이스 부분과 타워 부분에서의 바닥슬래브의 면내 변형으로 인하여 모든 층의 층 변위가 크게 증가됨을 알 수 있다.

Rheumatoid arthritis as one of the chronic illness requiring management in long period of time puts great burden to patients, their family and society. For patients with chronic illnesses, providing a social support is important and the most important source comes from spouses. Therefore we assessed burden of husbands of female rheumatoid arthritic patients and also found out the factors affecting burden. The sample of study was 107 female rheumatoid arthritic patients and their spouses. The tool of assessing spouses' burden was the revised version of subjective and objective parameters developed by Montgomery et al.(1985). The results are as follows: 1. General characteristics of patients and spouses: The mean age of the patients was 48 years. Educational level of patients was high school 41.1%. The mean age of the spouses was 51years. Educational level of spouses was mostly high school(40.2%) and college(29.9%) graduate. The mean marital period was 23.4years. Average income per month was 1,609,000 won. The average duration since diagnosis was 9.4years. As a therapy, 67.3% chose standard drug therapy. Average rating of discomfort by patient was 3.05(range 1-5) and that of severity was 3.48 and that of dependency was 2.58. The husband's rating of their spouses disease severity was 3.68. 2. Husbands' burden: The average burden in subjective items was 21.61(range 6-36) and objective items was 35.24(range 10-60). The average of total burden was 56.59(range 16-96). 3. Husband's total burden correlated with patient's age, educational level of patients, therapy method, patient's level of discomfort, patient's severity, patient's level of dependence, husband's recognition of level of severity in statistical level. Husband's objective burden correlated with patient's age, educational level of patient, patient's level of discomfort, husband's recognition of level of severity. Husband's subjective burden correlated with patient's age, educational level of patients, therapy method, patient's severity, patient's level of dependence, husband's recognition of level of severity. 4. Linear correlation analysis on burden: The husbands' total burden is explained in 37 7% by husband's recognition of level of severity and husband's age. The husbands' objective burden is explained in 31.2% by patient's level of dependence, husband's age, husband's recognition of level of severity. The husbands' subjective burden is explained in 26.7% by husband's recognition of level of severity and patient's age. In conclusion, husbands' level of burden is affected by many factors and therefore nursing strategy for relieving burden of middle aged husbands should be individualized taking these factors into consideration.

In this study, the clinical safety and toxicology of oral ingestion of supplement capsules containing ginseng radix was investigated in healthy young volunteers. This study was a pilot randomized, double blinded, placebo controlled trial. The healthy volunteers were divided into 6 groups of 20 each (10 males and 10 females). They took the ginseng powder for 35 days (3g/day) for safety evaluation. There were measured general healthy levels such as hematological, biochemical and electrocardiographic parameters. After the first week, besides Korean white ginseng the other treatments led to an significant increase of white blood cells. Korean red ginseng increased UREA (blood urea nitrogen) in healthy volunteers, but it didn't exceed the range of normal values, and in the subsequent process of treatment there is no effect of elevating UREA. After the three weeks, Korean white ginseng showed relatively low the content of blood glucose and low-density lipoprotein cholesterol. After the five weeks, compared with the other treatments, Korean red ginseng increased white blood cells, platelet distribution width and average volume of platelet. Korean white ginseng decreased low-density lipoprotein cholesterol. American ginseng decreased blood creatinine in healthy volunteers. In conclusion, through test the blood routine, urine routine, liver function, renal function, blood glucose, blood lipid and electrocardiogram, the healthy volunteers continuous taking ginseng for 35 days (3 g/day) is safe and reliable, and have no obvious adverse reactions and side effects.

방사성폐기물 지층 처분을 위한 부지 선정 과정에서 심층 처분장의 안전성을 평가하는데 필요한 입력 자료를 제공하기 위해 부지특성조사를 수행한다. 본 논문에서는 부지특성조사를 선도하여 수행하였던 해외 사례를 분석하고, 국내에서 방사성폐기물 처분을 위해 수행해야 할 부지특성조사 방법을 제안하고자 하였다. IAEA가 고려하는 부지특성조사 방법은 단계별 부지특성조사로 본 논문에서 소개된 해외의 경우도 이 방법을 따르고 있는데, 부지특성조사는 시기별, 조사 항목별로 다수의 지역에서 개략적인 부지의 정보를 도출하는 예비 부지특성조사와 조사 결과 선정된 지역에서 보다 자세한 부지특성자료를 생산하기 위한 상세 부지특성조사로 구분할 수 있다. 특히, 상세 부지특성조사 단계에서는 조사지역에 장심도 시추공을 굴착하여 심부 영역에 대한 지질 특성을 바탕으로, 수리지질, 수리-지화학, 암석역학, 열, 용질이동에 대한 특성을 도출해야 한다. 단계별 부지특성조사를 통해 도출된 부지 고유의 지질환경 특성은 부지특성모델로 구축되어야 하는데, 이를 종합하여 해석해야 비로소 조사지역의 부지특성을 이해하고, 지층 처분에 보다 유리한 부지를 최종 후보지역으로 선정할 수 있는 것이다. 해외 사례를 살펴본 결과, 부지특성조사 단계에 소요되는 시간은 대략 7~8년이 소요될 것으로 예상되나, 이를 계획하고 수행하는 시스템이 뒷받침 되지 않을 경우 보다 지연될 수 있을 것이다.

Background: Rounded shoulder posture (RSP), a postural abnormality, might cause shoulder pain and pathologic conditions. Although most previous research has investigated RSP focusing on the proximal structures of the shoulder, such as the scapula and pectoralis muscles, the relationship between RSP and anterior distal structures of the upper extremity, such as the biceps brachii muscle and elbow joint, is not clearly understood. Objects: This study aimed to investigate the correlations between RSP and the biceps brachii length, elbow joint angle (EJA), pectoralis minor length, general pectoralis major length, humeral head anterior translation (HHAT), glenohumeral internal rotation (IR), external rotation (ER), and horizontal adduction (HAD). Methods: Twelve subjects with RSP (6 male, 6 female) were recruited. All subjects fulfilled the RSP criteria indicated by a distance ${\geq}2.5cm$ from the posterior aspect of the acromion to the table in the supine position. The examiner measured each of the following parameters twice: RSP, biceps brachii length, EJA, pectoralis minor length, pectoralis major length, HHAT, glenohumeral IR, ER, and HAD. Pearson's correlation coefficient(r) was used to assess the correlation between RSP and all the variables. Results: There was a significant moderate positive correlation between RSP and biceps brachii length (r=.55, p=.032), moderate negative correlation between RSP and pectoralis minor length (r=-.62, p=.015), and moderate positive correlation between RSP and HHAT (r=.53, p=.038). Conclusion: The biceps brachii length, pectoralis minor length, and HHAT could be used to evaluate patients with RSP. Better understanding of the correlation between these factors and RSP could help in the development of effective methods to treat patients with this condition in clinical management.

The purpose of this study was to assess the effect of polycaprolactone strip with minocycline on the periodontal pocket in humans and the various clinical parameters in rapidly progressive periodontitis. Nine patients with rapidly progressive periodontitis were selected for the study. They had not taken antibiotics for 6 months and had no history of dental treatment for 6 months before the study. They were in good general health. By the split-mouth method, patients received a supragingival scaling, experimental group (9sites) were subjected to subgingival placement of polycaprolactone strips(1 strip) containg 30% minocyclne and control group (9 site) were subjected to subgingival placement of not polycaprolactone strips(1 strip) containing 30 A Minocycline. Strips were replaced with freshly filled ones at 1 week and 2 week. All strips were removed from pockets at 3 week Clinical examination (plaque index, gingival index, probing pocket depth) and distribution on the bacteria morphology of subgingival plaque were monitored on baseline (0 week), 1, week, 2 week, 4 week and 8 week. The result were as follows : 1. Plaque index in experimental group was not significantly reduced during all weeks(P<0.05), but slightly reduced at 2, 4 and 8 weeks and that in control group was not significantly reduced during monitoring period. 2. Probing pocket depth was significantly reduced at 2, 4 and 8 weeks(P<0.05) in experimental group, but that in control group was not siginificantly changed during monitoring period. 3. Gingival index was significantly improved at 2, 4 and 8 weeks(P<0.05) in experimental group but that in control group was not significantly changed. 4. Percentage of cocci was significantly increased at 2, 4 and 8 weeks in experimental group but that in control group was not significantly changed. 5. Percentage of non-motile rods in both group were not significantly changed when compared with those of baseline(0 week) (P<0.05). 6. Percentage of motile rods was siginificantly reduced at 1, 2 and 4 weeks in experimental group (p<0.05) but that in control group was not significantly changed. 7. Percentage of spirochetes was siginificantly reduced during all weeks(P<0.05) but that in control group was not significantly changed. The result showed that polycaprolactone containing 30% minocycline effect the clinical index and bacterial morphotype.
