오세진(Se-Jin Oh),김성철(Sung-Chul Kim),고주인(Ju-In Ko),이진수(Jin-Soo Lee),양재의(Jae E. Yang) 한국토양비료학회 2011 한국토양비료학회지 Vol.44 No.6

본 연구는 다량의 중금속을 함유하는 폐석탄 광산에 적치된 폐석으로부터 발생하는 침출수의 안정화를 위해 석탄회를 안정화제로서의 적용성을 평가하는데 목적이 있다. 석탄폐석에 석탄회를 적용하여 컬럼시험을 수행한 결과는 다음과 같다. 1) 석탄회의 pH는 비산재와 바닥재가 각각 11.1, 9.7의 강알칼리성을 갖는 것으로 나타나 강산성 조건의 폐석 (pH 3.5)를 교정하였으며 유기물을 비롯하여 식물생장에 필요한 영양소인 인산, 칼슘 등을 함유하는 것으로 나타나 폐석과 혼합할 경우 비옥도가 개선될 수 있을 것으로 판단된다. 2) 폐석만을 충진한 컬럼에서 발생하는 침출수의 pH는 3.5~4.0의 수준을 시험기간 동안 지속적으로 유지하는 것으로 나타나지만, 석탄회의 처리량에 따라 40% (pH 5.0~6.0) 〉 20% (pH 4.5)로 나타나고, 동일 처리량 (40%)의 처리방법에 따른 효율성은 완전혼합 (pH& & 5.0~6.0) 방법이 층위처리 (pH 4.0~4.5)에 비해 pH 상승효과가 높은 것으로 조사되었다. 3) 침출수의 Ca과 Mg의 함량은 4 pore volume까지 빠르게 용탈되다 그 이후부터 안정화 되었으며 석탄회에서 용탈된 Ca과 Mg의 영향으로 폐석에 함유되었던 Cu, Pb, As, 및 Al 등이 탄산이온 (CO₃<SUP>2-</SUP>) 또는 수산화이온 (OH-)과 불용성 화합물을 형성하여 안정화 되는 것으로 사료된다. 4) 철의 용존함유량에 대한 분석결과 석탄회 처리구의 용존량이 석탄회를 40% 층위처리한 처리구를 제외하고 대조구에 비해 약 8-74% 정도 감소하는 것으로 조사 되었다. 5) 석탄회를 이용한 폐석의 중화 및 철의 용존량 감소 효율성을 평가한 결과 폐석의 중화 효율성은 석탄회를 40% 완전혼합한 경우 가장 높았으며 철의 용존량 감소 효율성은 석탄회를 20% 완전혼합한 경우가 가장 좋은 것으로 조사되었다. 따라서 석탄회를 이용하여 현장에서 폐석을 처리할 경우 약 20-40%의 석탄회를 처리해야 높은 효율성을 얻을 수 있을것으로 사료된다. In this study, coal combustion ash (CCA) was evaluated for its stabilization effect on acidic mine waste with column experiment. Total of six treatments were installed depending on mixing ratio between coal wastes and CCA (0, 20, 40%) and mixing method (completely mixing and layered). Artificial acidic rain (pH 5.6) was used for feeding solution with flow rate of 0.05 mL min<SUP>-1</SUP>. Result showed that higher pH of leachate was observed as more CCA was mixed. The highest pH in leachate was measured when 40% of CCA was mixed with coal waste (pH of 5.8). Also, complete mixing with CCA and coal waste was more effective to increase the pH of leachate than layered treatment. Regarding the reduction of soluble Fe amount, the highest efficiency (78%) was observed when 20% of coal ash was completely mixed with mine waste. Based on those result, optimum mixing ratio of coal ash with mine waste can be ranged 20-40% depending on environmental circumstances in the field.

Sleep is an essential component in health and the quality of life of individual. Normally, sleep pattern changes with advancing age. These changes often result in sleep impairment and become a major stressor in elderly. Even though the elderly is the fastest growing population, sleep impariment among elderly has not been well documented, few studies have been conducted related to the sleep of the elderly in Korea. The purpose of this study is to explore sleep pattern, related factors, and sleep satisfaction among healthy community-dwelling elderly, in order to present basic informations regarding Korean elder's sleep. 170 subjects over 60-yer-old were participated in the study. The survey questionnaire was developed by translation and modification of two well-known sleep questionnaires which originally developed by Monroe(1967) and Ellis, et al.(1982). Pilot study was done liefore final contents of a questionnaire was organized. SPSS/PC+ was utilized for data analysis. Results as follows: 1. Sleep pattern changes were reported by 75% of the subjects: decline in sleep time: frequent awakening: difficulty in falling asleep; lack of deep sleep; falling asleep early and getting up early; sleepy; decline in early morning sleep; irregular sleep habit; early retiring in bed. 2. Most of the subjects reported to fall asleep between 9-11pm, and get up between 4-6am. Forty point one percent of the subjects stated that they have problems in falling asleep. More than 70% reported their sleep to be satisfied. Sixty one point eight responded that they hardly or never take a nap. 3. Regarding sleep-disturbing factors, physical factor(30.1%), emotional factor(44.2%), environmental factor(41.0%) were reported. 4. Nineteen point two of the subjects practiced some types of strategies for better sleep. But a few(12.8%) used hypnotics, mainly in occasional base. 5. Variables showed statistically significant differences in sleep satisfaction were; getting up right away upon waking; frequency of awakening during night time sleep; difficulty in falling asleep; feeling rested upon waking int eh morning ; difficulty in going back to sleep upon awakening during night time sleep. From the results of this study, it can be concluded that the elderly in the community do have some sleep impairment but do not practice adequate strategies for better sleep. Further research are needed to develop better sleep measurement tool, to compare sleep pattern with other age groups and to develop nursing intervention.

There have been so many researches about problems of cigarettes and relation of smoking and heath since 1950's and generally known that smoking is one of the worst factor of increasing disease and mortality. No matter what such many proofs about various problems of smoking have been researched, smoking rate of current male collage students has not been decreased. Besides, most of the researches about cigarette use and its addiction have been focused on the adolescent or adult women smokers or adult male, not male collage student. Therefore, the subject of this study is about smoking attitude and smoking behavior of male collage students by general features. Smoking attitude was analyzed by modifying 'Guidelines for the content of tobacco smoking surveys of the general population'(WHO, 1982). Two hundred of male collage students participated to the distributed questionnaire for one week in May. The smoking attitude was categorized into duration of smoking and number of cigarette per day(CPD), and nicotine dependency, investigated by Fagerstrom Tolerance Questionnaire(FTQ) (Fagerstorm & Schneider, 1989). All statistics were performed by procedure of SAS according to number, percentage, mean, standard deviation, and ANOVA. The results are as follows: 1. Smoking attitude level was mean 25.73±5.15 marks, ranging from 13 to 39 marks of the total 40 marks. 2. Duration of cigarettes, number of cigarette per day, and nicotine dependency were mean 5.14±2.84 years, 12.88±6.85 pieces, and 4.78±1.69, respectively. 3. Smoking attitude showed significance according to general features such as marital state and allowance, but the significance according to marital state is not valuable because the numerical difference is so big between married one and single that they cannot be compared with each other. 4. Duration of smoking was significant according to general features such as age and allowance. 5. Smoking amount showed significance the factors of age only. 6. ll1ere was no significance in nicotine dependency according to general features. As a result, smoking attitude of male collage student in this study shows moderate level. Smoking attitude and duration is significant according to allowance, and smoking amount is significant according to age. Nicotine dependency according to general features is not significant but comparing with the preceding study about adult male, male collage students in this study are respectively more nicotine-dependent than adult male smokers. In conclusion, the right allowance usage strategies and effective heath education focused on the young are needed. In addition, helpful programs and information spreading strategies are necessary for establishing higher level of smoking attitude. At last, systemic regulations in daily living for ""anti-nico-dependent"" and perspective reforming of male university student are needed for reducing nicotine dependency.

In this study we investigated the effects of supine ergometer exercise on physiological and psychological relaxation. Seven healthy young men(aged 24.4±2.00years) volunteered for the experiment. The experiment consisted of the following three successive segments" A pre-exercise period of 10 min, during which the subjects rested in a supine posture with their eyes closed for the final 5 min; an supine ergometer exercise period of approximately 10 min, during which the subjects performed intensity of 50%HRmax exercises; A post-exercise recovery of 5 min, and a recovery of 10 min, which was similar to the pre-exercise rest period. The electroencephalo-graphic(EEG) activity of the central cortex of the brain were measured pre-exercise, post-exercise 5 min, and recovery phase 10min. Fast Fourier Transformation of the EEG was used to obtain power spectrum areas in the delta(0.5~4 Hz), theta(4~8 Hz), alpha(8~13 Hz) and beta(13~30 Hz) frequencies. We compared the relative power values(power %) of the electroencephalogram alpha bands(8~13 Hz) and korean edition of the profile of mood states(K-POMS) before and after the supine ergometer exercise. We also estimated the percentage of maximal heart rate(%HRmax) throughout the experiment to ascertain the intensity of the supine bicycle ergometer exercise. The results of %HRmax indicated that the intensity of supine exercises practised in the experiments ranged from low to moderate. The power % of EEG alpha bands had increased significantly after the supine ergometer exercise compared with the pre-exercise rest(p<0.05). From the POMS results, we observed that positive mood(vigour) increased and negative mood(tension, depression, and total mood)decreased significantly after the supine ergometer exercise(p<0.05). This study found that the subjects showed increased physiological and psychological indices of relaxation after supine bicycle ergometer exercise.

목적 : 2002년 말 중국에서 SARS가 발생한 이후 국내에서도 2003년 10월까지 총 3명의 추정환자, 17명의 의심환자가 보고되었다. 향후 추가적인 SARS의 유행이 우려되는 상황에서, 그간의 SARS 환자 진료에 있어서의 실질적인 준비사항, 진료 현황 등에 대한 조사를 통해 문제점을 파악하여, 향후 더 나은 대비가 될 수 있도록 개선점을 제시하고자 하였다. 재료 및 방법 : SARS로 의심되는 환자를 진료 경험이 있는 병원의료진을 대상으로 2003년 10월에 설문조사를 실시하였다. 설문에는 SARS 환자 진료 시의 실질적인 조치, 진료 현황, 병실, 응급실 및 외래에서의 격리 시설과 준비사항, 보건당국의 관리와 지원에 관한 사항을 포함하였다. 결과 : 대상이 되는 22개 병원 중 17개(17/22, 77.2%) 병원이 설문에 응하였다. SARS 환자를 위한 격리실은 응급실, 외래, 일반병실 및 중환자실에서 각각 9개(9/17, 52.9%), 5개(5/17, 29.4%), 15개(15/16, 93.7%), 4개(4/16, 25%) 병원에서 음압처리가 되어있지 않은 일인실 혹은 다인실이 사용되었고, 1개(1/16, 6.3%) 병원에서만 일반병실에서 음압격리실이 운영되었다. 입원환자의 진찰 시 개인보호구의 착용은 거의 모든 의료기관에서 이루어졌다. 보건당국에서 SARS지정병원의 시설 등을 사전에 확인한 곳은 1곳(1/12, 8.3%)이였고, 14개 병원(14/15, 93.3%)에서는 보건당국에 의뢰한 검사결과를 통하 받지 못하였다. 결론 : 의료기관에서 SARS 환자용 격리실뿐만 아니라 기존의 격리실 설비 등이 미흡하였으며, 특히 중환자실 및 외래의 준비가 더욱 부족하였다. 보건당국의 의료기관에 대한 종합적인 지원이 부족하였고, 병원과의 원활한 연계가 잘 이루어지지 않았다. SARS 만이 아닌 격리를 필요로 하는 질환의 적절한 진료를 위해 향후 병원 시설의 정비와 정부차원에서의 보다 구체적이고 실질적인 대책마련이 필요하다. Background : There was an worldwide outbreak of the Severe Acute Respiratory Syndrome (SARS) originated from China in late 2002. During that period three cases of suspected SARS and 17 cases of probable SARS were reported in Korea. With the concerns about the reemergence of SARS-coV transmission, it is important to be prepared for any possibility. So, this study is aimed to analysis the past measures in managing SARS and propose the amendatory plans to improve the preparedness. Materials & Methods : Questionnaires were collected among clinicians with any experience in managing the probable or suspected SARS cases in Oct. 2003. 17 out of 22 hospitals responded to the questionnaire. The contents in the questionnaire were practical activities, personal equipments, response plans, isolation facilities in emergency centers, outpatient clinics, general wards and intensive care units, and relationship with the public health department. Results : The dedicated isolation rooms in emergency centers, outpatient clinics, general wards, and intensive care units were prepared in 9 (9/17, 52.9%), 5 (5/17, 29.4%), 15 (15/16, 93.7%), and 4 (4/16, 25.0%) hospitals, respectively. Except for one hospital that newly made negative pressure room for SARS, single or multi-bed rooms without airborne infection control were used in all the other hospitals. The personal precaution principles were kept quite well in general wards. Before the designation of SARS hospital by the public health department prior evalution to see if the hospital was suitable for managing SARS was conducted in only 1 (1/12, 8.3%) hospital. The results of laboratory diagnosis were reported back in 1 (1/15, 6.6%) hospital. Conclusions : The isolation facilities which can control airborne infection were almost deficient not only for SARS but also for other respiratory transmissible diseases. For the infection control of transmissible diseases including SARS, more investment is needed on medical facilities and comprehensive support from the public health department required.
