It is possible not only to treat high concentration organic matter such as food wastes but also to utilize food wastes as resources according to the bio-energy generation such as methane. The method of co-digestion of mixed wastewater mixed with organic wastes such as sewage sludge concentrated waters together with drinking wastewater is the most ideal method. Radiation not only has germicidal power in water treatment, but also is effective in decomposing degradable organic matter. Second chemical contamination problem is also solved because it does not use chemicals. Introduction of radiation pretreatment system to solve problems caused by mixing of waste water and organic waste resources. Biological electrochemical fusion system is used to remove the nutrients contained in the organic matter-removed mixture. Through the development of a system for treatment of high concentration wastewater, the processing efficiency is verified through the universal water treatment system for wastewater containing high concentration organic matter in addition to treatment of wastewater.

This paper presents a fault location algorithm of a single phase-to-ground fault on a parallel transmission line which contains a teed circuit. The method uses only the local end voltage and current signals. Zero sequence currents of other lines are calculated by distribution factors. Instead of zero sequence current, negative sequence current is used to remove the effect of load current and to calculate the voltage of a fault resistance. There are three distance equations in this algorithm. One of them is to calculate inner part fault location without teed circuit and another equation is for outer part fault location without teed circuit and the other is to calculate inner part fault location with teed circuit. Correct fault distance is selected by the condition of each solution. Extensive simulation studies using EMTP have verified that the proposed algorithm can calculate an accurate fault distance in spite of effects of various error sources.

저축대안별 세금효과에 관한 연구

Numerous savings vehicles are available to save for future consumption, In this paper, a number of savings vehicles are considered that were distinguished by the tax treatment of investment returns. While investments made in most savings vehicles do not give rise to immediate tax deductions, investments in pensions do, in America. While the earnings in some investments are taxed annually, the earnings in others are partially or fully tax-deferred or may be tax exempt altogether. Earnings in some vehicles are taxed at ordinary rates while earnings in other vehicles attract tax at capital gains rates. Because of these deffering tax treatments, the after-tax accumulation and rate of return from holding a fully-taxable bond in each of these savings vehicles raries dramatically across the alternatives. With constant tax rates over time, pension savings and tax-exempt savings through insurance contracts dominate money market accounts and such other savings vehicles as single premium deferred annuities. Without frictions and restrictions, the dominant returns available from some patterns would result in tax arbitrage opportunities. Investors would save only through the dominant patterns. If tax rate changes through time, the dominance relations can disappear. For example, when tax rates are increasing over time, money market accounts (the least tax-advantages vehicle when tax rates are constant) can provide higher after-tax rates of return than pension accounts(the most tax-advantageous vehicle when tax rates are constant). The introduction of frictions and restrictions further alters the rankings of the alternatives. Empirically, we find that investors use all of the vehicles that we analyzed to save for future consumption. When we add cross-sectional differences in tax rates and investment opportunities, additional tax-planning opportunities arise that can be exploited through personalized contracting. For example, it may be advantageous to undertake savings through deferred compensation contracts. An important lesson here is that the tax positions of both the employee and employer must be considered to determine whether deferred compensation represents an effective organizational arrangements, such contracts may be undesirable when employer tax rates are also falling through time. When opportunities exist to contract in personal markets, effective tax planning requires that we consider the tax and investment opportunities of all parties to the contract, It is convenient to make all but one of the parties indifferent across the contract alternatives in deciding which tax-planning alternative is favored. Nontax factors, such as motivational and risk-sharing considerations between employees and employers, might tip the choice in favor of current compensation even though compensation is tax-favored, or vice versa.

정상체중을 가진 성인 남성에서 지방과다(adiposity)와 심혈관계 질환의 위험요인과의 관련성을 알아보고자 하였다. 2001년 1월 3일부터 12월 31일까지 영남대 학교의료원에서 종합검진을 받은 만 28∼69세 성인 남성 129명을 대상으로 연령, 신체계측, 혈압, 공복 혈당, 혈청 지질대사치와 체성분 검사를 실시하였다. 체질량지수(BMI)가 18.5∼23 kg/㎡(76명)인 정상체중군과 23∼25 kg/㎡(53명)인 과체중군으로 분류하고, 체비방률, 체지방량과 위험인자들(수축기혈압, 이완기혈압, 공복시 혈당, 중성지방, 저밀도지단백, 고밀도지단백)의 상관관계를 분석하고, 정상체중군을 지방과다에 따라 3군으로 나누고, 각 군과 과체중군에서 심혈과 질환의 위험인자를 평가하였다. 정상체중의 제1군을 기준으로 제2, 3군과 과체중군의 위험인자 존재에 대한 비차비(odds ratio)를 조사하였다. 정상체중군에서 지방과다 변수들(adiposity variables: 체지방량, 체지방률)과 수축기 및 이완기 혈압, 저밀도지단백, 중성지방에서 유의한 상관관계가 있었다. (P<0.01). 나이를 보정하고 난 뒤 제1군을 기준으로 제3군(체지방율: 3.7, 체지방양: 4.7)과 과체중군(체지방율: 6.6, 체지방양 11.5)에서 위험인자에 대해 더 높은 비차비를 가졌다. 지방이 많은 정상체중의 성인남성은 적은 지방을 가진 성인 남성보다 심혈관 질환에서 더 높은 유병 위험도를 가졌다. 지방 측정은 정상체중군에서 심혈관계 질환의 위험인자외에 추가적인 정보를 제공할 수 있었다. Background: Most of all studies about the relation between the health risk and obesity are based on the European and American data. The purpose of this study is to examine the relation between adiposity and factors for cardio vacular disease (CVD) in normal weight individuals. Materials and Methods: Normal weight subjects with a body mass index (BMI) between 18.5 and 23 kg/㎡(76 subjects) and overweight subjects with a BMI between 23 and 25 kg/㎡ (53 subjects) were retained for this study. Normal weight subjects were divided into three group of each adiposity variable, then three group and the overweight group were evaluated for the presence of CVD risk factors and analyze the correlation coefficients between adiposity variables and risk factors controlled for age in normal weight, overweight groups. Using logistic regression analysis, the odds ratio (OR) for the prevalence of risk factors for each group of adiposity variables and the overweight group was estimated relative to the first group in normal weight subjects. Results: Systolic BP, diastolic BP, LDL cholestrol, HDL cholesterol, triglycerides in normal weight subjects were significantly correlated with all adiposity variables (P<0.01). Third group (3.7 for %fat and 4.7 for fat mass) of adiposity variables in the normal weight group and the overweight group (6.6 for %fat and 11.5 for fat mass) tended to have higher ORs compared to first group for risk factor variables. Conclusion: Normal weight subjects with elevated adiposity had higher prevalence of risk factors than normal weights subjects with less adiposity. Measuring of adiposity added additional information of cardiovascular disease risk factors in normal weight subjects.

It is generally known that demonstration of absence of cerebral blood flow is necessry to confirm brain death. Transcranial Doppler(TCD) is an accurate method of monitoring the blood flow velocities of the cerebral vessels. We performed transcranial doppler(TCD) examinations on 15 patients in brain death. Anterior criculation was examined through the temporal window or transorbiral window and basilar arteries were examined through the suboccipital window. All of the patients fulfilled the criteria for determination of brain death by clinical criteria, EEG and/or Brainstem Auditory Evoked Response(BAER) or clinical criteria alone, were mechanically ventilated. A TCD waveform abnormality consisting of reversed diastolic components was found in all brain death patients. The net flow veloicties of <10 ㎝/sec were present in all brain death patients. TCD may be a rapid and convenient alternative to cerebral angiography for confirming brain death when institutional protocols require such comfirmation.

Objectives:The aim of this study was to evaluate that problem solving styles, interpersonal problems, depression and suicidal ideation according to body image satisfaction. Methods:One hundred and nineteen young healthy normal subjects filled out administered the Body Dysmorphic Disorder Examination-Self Report (Korean version of BDDE-SR K-BDDE-SR), Problem Solving Style Scale(Korean version PSS), Korean Inventory of Interpersonal Problem(KIIP), Korean version of the Depression Anxiety Stress Scale(KDASS-21), Korean version of Beck Scale for Suicidal Ideation(Korean version SSI) and Korean version of Reynolds Suicidal Ideation Questionnaire(Korean version SIQ) for a month. Results:Out of the 119 subjects, 39%(N=46) was male and 61%(N=73) was female. In high K-BDDE-SR group (higher than 67), helplessness was significantly higher than low K-BDDE-SR group(lower than 67), and problem-solving confidence, creative style, approach style were significantly lower than low K-BDDE-SR group. Also, Higher level of all KIIP factors in High K-BDDE-SR group was significantly differ than low K-BDDE-SR group. In High K-BDDE-SR group, K-DASS-21, SSI, and SIQ were significantly higher than low K-BDDE-SR group. Using multiple regression analysis contributing variance toward the total factor score of K-BDDE-SR of participants were K-DASS-21 and SIQ. Conclusion:Our results indicates that high tendency of dissatisfied body images have differences in helplessness, problem-solving confidence, approach style, interpersonal problems, depression and suicidal ideation compared to low tendency of dissatisfied body images. It is necessary to study body dysmorphic disorder patients group in the future.
