Solvent extraction and stripping experiments were conducted to separate iron from a spent FeC13 etching solution containing nickel. In the operation of mixer-settler, 7 extraction stages with 1.0 M Alamine336 in toluene, led to 98% extraction percentage of iron at equal phase ratio, when the flow rate of organic and aqueous were 35 mL/min and 5 mL/min, respectively. At equal phase ratio of aqueous to organic, 10 stripping stages with 0.01 M HC1 solution resulted in 99% stripping percentage of iron when the flow rate of stripping solution and loaded organic were 5 mL/min and 35 mL/min, respectively. The concentration of iron in the stripped solution was 133 g/L and this solution could be reused in the etching of nickel lead frame. (Received June 15, 2004)

This study is intended to investigate medication compliance and polypharmacy of the diabetic patients by age group in order to determine the major factors that influence their compliance. 198 ambulatory diabetic patients were interviewed, and the sample was divided into three groups based on the age: Young age group under 75, Borderline age group between 55 - 65, Old age group over 65. According to the study results, medication compliance for the old age group was 72.6% whereas 85.1% for the young age group. Medication compliance significantly decreased as the age of the patients increased. Also the degree of polypharmacy, the rate which patients take more than 6 prescription drugs, was 45.9% for the old gruop, whereas 31.2% for the young group. As the most important factor of polypharmacy, the number of doctors was statistically significant. With regard to prescription factors related to medication compliance, the amount of prescribed medication is statistically significant between the compliance group and non-compliance group. In addition, the amount of information provided to patients by pharmacists was determined to be a very significant factor. Also the level of ease in understanding the medication instructions varied significantly between the compliance group and the non-compliance group. In light of the empirical data and results for the diabetic patients, it is necessary to develop and implement various programs to improve medication compliance and to decrease the level of polypharmacy among the elderly, or "old", diabetic patients.

[Background] Phthalates are ubiquitous industrial chemicals used as plasticizers, solvents, lubricants, and stabilizers in the manufacture of consumer products such as children`s toys, medical equipment and medications, cosmetics, and food packaging. Assessing human exposure to phthalates is of interest because of their potential adverse health effects, particularly among the young. [Objective] The national survey for environmental exposure monitoring in 2009 were funded by Korea Food of Drug Administration (KFDA) with a view to assessing human exposure to selected chemicals including phthalates and identifying major sources of them. [Methods] The subjects of our study aged between 18 and 70 were selected through stratified sampling nationwide and interviewed by trained interviewers using structured questionnaire to collect information on general characteristics, use of plastics, dietary habits related with potential exposure to phthalates. Total 1,874 urine samples were collected and stored at -20℃ until measurement for 10 selected metabolites of phthalates using HPLC (high performance liquid chromatography). Out of 10 metabolites, six ones were selected for further statistical analyses based on proportion of samples over LOQ (limit of quantification), i.e, MnBP, MiBP, MbZP, MeHP, MeOHP, and MeHHP. For each urinary levels (ug per gram creatinine), geometric mean and 50th, 75th, 90th, 95th were represented. Given the distribution of response variable deviates from normal distribution, log transformation was performed, and then tested for its statistical significance. Differences by selected variables were analyzed for statistical significance by ANCOVA (analysis of covariance) adjusted for age, sex, income, and body mass index. [Results] Common phthalate metabolites included MnBP (GM=41.7, GSE=1.9), MeHHP (38.1, 1.9), MeOHP (17.5, 1.9), MiBP (17.0, 2.2), and MBzP (15.8, 2.8), whereas the proportion of data above LOQ was less than 20 for MCHP, MnOP, MiNP, and MiDP. The levels for the six metabolites tended to be higher compared to those from the national survey in US (NHANES), and lower compared to those from the national survey in Germany (GerES4). Significant correlations between the six urinary metabolites were observed. Urinary level of phthalates were observed to be higher among subjects with older age, females, subjects with higher body mass index (BMI), and lower income.

Rhabdomyolysis is a biochemical and clinical syndrome caused by lysis of skeletal muscle cell and release of muscle cell contents into the circulation. In addition to traumatic cause, various nontraumatic causes have been reported. Rhabdomyolysis has frequently been associated with seamy aspects of life and society: alcoholic abuse, drug addiction, sadistic drill exercise, war events and attempted suicide. The abuse of alcohol causes many hazards in many organs. One of these is acute alcoholic myopathy that may present as a fulminent syndrome of muscle pain and tenderness associated with rhabdomyolysis and acute renal failure. Because the prognosis of adequately treated rhabdomyolysis is excellent, early recognition and prompt management are essential in emergency situation. We experienced two typical cases of alcohol-induced rhabdomyolysis with acute renal failure and report these cases with literature review.

The aim of this study was to investigate the posttraumatic stress symptoms of violent crime and predictors to the symptoms. For this, we analyzed data of 473 victims registered to the integrated supporting center for violent crime victims who agreed to participate in the study. The results showed that more than 90% of victims experience significant PTSD symptoms, 30% of them were in extreme mental confusion that required medication or hospitalization. There was a significant difference in the severity of sequela according to gender, time since visiting to the center, pre-event adaptation level, and event type. Although the victim experienced more avoidance and hypervigilance symptoms than the family, the psychological distress experienced by the family was not less than that of the victim. Psychological sequela of the events were found to be more severe with more experiences of childhood trauma, lack of ego resilience, low level of perceived social support, strong dissociation tendency, and avoiding coping styles. A result of the stepwise regression analysis, avoidant coping style explained 10.6% of the total variance. Limitations and implications of this study were discussed.

Background: Two major events occurring in the cerebral hemodynamics after successful resuscitation from cardiac arrest are reactive hyperemia and postischemic hypoperfusion. In this study, we examined the effect of Pentoxifylline(PTX) on the rat brain following cardiac arrest. Methods: Fourteen rats were anesthetized and artificially ventilated. Cardiac arrest was produced by chest compression and clamping of tracheal tube for 3 minutes in ketamine anesthetized rats. Circulation was restored by standard cardiopulmonary resuscitation methods. In 7 rats, PTX 10mg/kg was infused at 10min after cardiac arrest(PTX group). In the other 7 rats, same amount of normal saline was infused(control group). Results: In both groups, hemodynamic variables, neurologic deficit(ND) score and histopathologic findings of hippocampal CA1 neurons were observed. Hemodynamic variables and ND score were not significantly different between two groups. Delayed ischemic neurons of hippocampal CA1 were decreased in PTX group(2.2±2.4%) compared with control group(9.1±1.2%). Conclusions: We conclude that PTX prevented development of delayed ischemic neurons in hippocampal CA1 after cardiac arrest. PTX may be useful in emergency situations following cardiac arrest.

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.

BMP test를 통한 음폐수와 하수슬러지의 병합소화 특성 평가

이수영ㆍ윤영삼ㆍ강준구ㆍ김기헌ㆍ신선경(Su young LeeㆍYoung Sam YoonㆍJun Gu KangㆍKi Heon KimㆍSun Kyoung Shin) 유기성자원학회 2016 유기물자원화 Vol.24 No.1

혐기성 소화의 주요 조건 중 하나인 C/N비의 경우 하수슬러지는 5.40으로 낮게 나타난 반면 음폐수(Food waste leachate)는 21.84로 높게 나타났다. C/N비가 낮을 경우 혐기성소화의 저해 요인으로 작용될 수 있기 때문에 음폐수의 높은 유기물 농도 및 C/N 비를 활용하여 메탄가스 발생량 증가시킬 수 있었다. Tchobanoglous이 제안한 이론적 메탄가스 발생량 예측수식을 적용하여 메탄 및 바이오가스 발생량을 산정한 결과 하수슬러지 단일 혐기소화의 경우 305.6 mLㆍCH4/gㆍVS, 689.4 mLㆍCH4/gㆍVS의 메탄, 바이오가스가 발생하였고 음폐수 : 하수슬러지를 1:9로 혼합한 시료는 약 322 mLㆍCH4/gㆍVS, 3:7시료에서는 약 354 mLㆍCH4/gㆍVS, 5:5시료에서는 약 386 mLㆍCH4/gㆍVS의 메탄가스가 발생하는 것으로 분석되었다. BMP 실험 결과 1:9, 3:7, 5:5 비율로 병합 처리한 경우 각각 약 233, 298, 344 mLㆍCH4/gㆍVS의 메탄가스가 발생하였다. 따라서 음폐수의 혼합비율이 높아질수록 메탄가스 발생량은 증가하였고 하수슬러지와 음폐수의 혼합 비율에 따른 병합처리 시 하수슬러지 단독처리에 비해 다량의 메탄가스가 발생되었다. BMP 실험을 통해 생산된 메탄가스의 누적생산 곡선을 Modified Gompertz model과 first order kinetic model에 적용하여 추정한 결과, 메탄생성량은 Modified Gompertz model에서는 238.5, 302.3, 353.6 mL/gㆍVS 발생하였고 first order kinetic model에서는 242.8, 312.5, 365.5 mL/gㆍVS로 음폐수와의 혼합비율이 증가할수록 높게 나타났으며, 최대 메탄생성속도의 경우 3:7비율에서 48.2 mL/gVSㆍday로 최대 메탄생성 속도를 보였다. first order kinetic model의 1차 반응속도상수 k값은 1:9, 3:7, 5:5 비율에 따라 0.32, 0.22, 0.08day-1 나타났다. 1차 반응속도 상수의 경우 음폐수의 혼합비율이 낮을수록 높게 나타났다. Modified Gompertz와 first order kinetic model 모두 실험결과를 잘 모사하였으며, 실험결과와 모의결과의 적합도를 나타내는 상관계수(R2)의 경우 0.92∼0.98으로 높은 상관성을 나타내었다. We mix food waste leachate and sewage sludge by the proportion of 1:9, 3:7 and 5:5. It turns out that they produced 233, 298 and 344 CH4ㆍmL/gㆍVS of methane gas. The result suggests that as the mixing rate of food waste leachate rises, the methane gas productions increases as well. And more methane gas is made when co-digesting sewage sludge and food waste leachate based on the mixing ratio, rather than digesting only sewage sludge alone. Modified Gompertz and Exponential Model describe the BMP test results that show how methane gas are produced from organic waste. According to the test, higher the mixing rate of food waste leachate is, higher the methane gas productions is. The mixing ratio of food waste leachate that produces the largest volume of methane gas is 3:7. Modified Gompertz model and Exponential model describe the test results very well. The correlation values(R2) that show how the results of model prediction and experiment are close is 0.92 to 0.98.
