This study aims to compare the mutual perception gap on dangerous driving behavior between male and female drivers in multiple aspects, analyze them, and identify factors that trigger this different perception. To understand the mutual perception gap on dangerous driving behavior, DBQ(Driving Behavior Questionnaire) was applied as a rating scale. By applying results into the Co-oreintation model, this study compared the mutual perception gap between male drivers and female drivers and analyze results. In addition, factors that generate the perception gap between both genders were drawn by analyzing factors. This study suggested that objective consistency identified the perception gap that driving behaviors of others were more dangerous between two genders. In addition, subjective consistency was different as both genders assumed that the counterpart's driving behavior takes more risks than their own actual driving behaviors. In regard to the accuracy, men were aware that female driving behaviors are more dangerous than their behaviors. However, female driving behavior assumed by women was consistent with male perception in all factors, which indicated that women perceive men precisely. In addition, results were compared and analyzed in both perspectives of male drivers and female drivers by combining predictive models. Based on these results, both genders perceived that counterpart's driving behavior is more dangerous among both genders.

The purpose of this study was to present basic research data to utilize magnetic resonance imaging (MRI) with analyzing intracerebral regional distributions of ischemic cerebrovascular disease of middle aged and oldest-old aged people. We retrospectively analyzed middle-aged group (average age of 44.2 year-old, 43 males, 26 females) and oldest-old aged group (average age of 84.7 year-old, 58 males, 71 females) who taken MRI screening for ischemic cerebrovascular disease from May 2006 year to January 2008 year. The intracerebral vascular were classified into 8 vessels, which anterior communication artery (ACoA), posterior communication artery (PCoA), anterior cerebral artery (ACA), middle cerebral artery (MCA), posterior cerebral artery (PCA), internal carotid artery (ICA), common carotid artery(CCA), and basilar artery (BA). The result of middle-aged group showed that more ischemic cerebrovascular diseases appeared in men than women, and it affected in MCA mostly. In oldest-old aged group, ischemic cerebrovascular diseases occurred evenly spaced in intracerebral region of right, left, and both vessels, and women have more than men. For men, the most occurred in ICA and for women the most occurred in MCA. Specially middle-aged group in men showed that more ischemic cerebrovascular diseases in MCA appeared than oldest-old aged group in men. It is suggested that the analysis on ischemic cerebrovascular could be helpful in the clinical diagnosis and treatment.

도시화 및 산업화는 가족의 애정기능 증대, 친족관계 약화, 공사영역분리, 여성의 교육수준 향상 및 취업기회 증가, 부부관계의 평등성 추구 등을 통해 이혼을 증가시키는 요인으로 알려져 왔다. 혼인·이혼신고 자료와 인구주택총조사 자료를 활용하여 1970년∼1995년 동안 발생한 한국의 성별, 연령별, 시도별, 교육수준별 이혼율을 비교하였다. 이혼수준을 측정하기 위하여 조이혼율, 일반이혼율, 연령별이혼율, 연령표준화 이혼을 전체인구와 유배우인구를 대상으로 각각 산출하였고, 각종 이혼력 지표의 특성을 논의하였다. 1970년∼1995년 동안 이혼율이 3배 증가하였으며, 1995년 현재 유배우인구 천 명당 3.2건의 이혼이 발생하였다. 동기간 동안 24세 이하 연령층의 이혼율이 가장 높았고, 전 연령층에 걸쳐 빠른 속도로 이혼율이 증가하였는데, 증년층의 이혼율 증가 속도가 가장 빨랐고, 남성보다는 여성의 상대적 이혼율 증가 정도가 더 빨랐다. 시도별 이혼율은 전연령층에 걸쳐 서울, 부산, 인천, 대전, 경기, 제주도가 높았고, 강원도와 전라북도 25∼34세 연령층의 이혼율이 높았다. 교육수준별 이혼율이 남자는 초등학교 졸업집단에서, 여자는 고등학교 졸업 집단에서 가장 높았고, 남자는 대졸 이상 집단, 여자는 무학 집단에서 가장 낮게 나타났다.

To provide physical therapy service of good quality keeping people healthy and obstain structural reformation coping with the demands of in medical service market to foreign intercourse on 21C, we should make legal system fer the physical therapy practice. Thus we suggest the Ministry of Health and Health and the authorities should, 1. Exclude the provision of physical therapist from the classfication of medical technician on the Medical Technician Law Article 2. and establish the independent Physical Therapist Law 2. Eliminate the provision of physician or dentist's guide the Medical Technician Law Article 1. or reform it to physician or dentist's request so that physical therapists may have a independent practice, or 3. Add the provision of the physical therapy center to the Medical Technician Law, the enforcement ordinances and enforcement regulations, such as the provision of optometrist or dental technician.

Colorants were extracted from the heartwood of sappan lin. with MeOH under reflux, and the concentrate or the powder of dye was prepared by low pressure concentration method using suitable organic solvent. Various components were isolated from sappan wood, and the chemical structure and mechanism of compound having the excellent antibacterial and deodorization properties were analyzed. The results obtained are as follows ; The seventeen components of sappan wood were seperated by HPLC chromatography, and the five components among them were existed more than 6% and the other components were existed lower than 0.6%. The resolving powers of the non-polar solvent and polar solvent systems were evaluated by their ability to resolve the samples. It showed that chloroform-methanol-water(800:150:10) system has the best resolving power. Although the seperation rate is very slow, polyamide C-100 column chromatography gives a clear seperation of sappan wood. On the basis of the spectrometric data such as IR, UV, $GC-Mass,\;^1H-NMR,\;^{13}C-NMR\;and\;^1H-^{ 13}C-NMR$, the chemical structure of compound haying the excellent antibacterial and deodorization properties was established as brazilin containing the functional groups such as two quaternary carbon, one benzyl carbon, methylene contiguous to oxygen and methylene caused by oxygen atom.

Colorants were prepared by extraction of natural indigo which was harvested just in the blooming season(in the late of July). 100 g of fresh leaves soaking in 1 ιwater was kept at 3$0^{\circ}C$, 30 hours. A solution of 3g/l calcium hydroxide was added into it to precipitate dye substance and it was freezing-dried into powder form. The fermentation and dyeing conditions were investigated. The results obtained are summarized as follows; K/S value of dyed silk fabrics of fermentation conditions was higher at 95$^{\circ}C$ for 20 min. than at 4$0^{\circ}C$ for 20 hours. Furthermore, K/S value of dyed silk fabric was raised by the addition of 5g/l of glucose and 5g/l of NaOH. K/S value of dyed silk fabric was raised by the addition of 5g/l of glucose and 5g/l of NaOH. K/S value increased as extending of dyeing time when dyed till 2 hours at 3$0^{\circ}C$. K/S value decreased in order of 3$0^{\circ}C$, 4$0^{\circ}C$ and 5$0^{\circ}C$, at the various dyeing temperatures and dyeing concentrations, and colour fastness ranged from 4 to 5 grade in terms of washing, perspiration and light fastness.

Stochastic rainfall-runoff process model which is mainly used in real-time streamflow forecasting is Transfer Function(TF) model that has a simple structure and can be easy to formulate state-space model. However, in order to forecast the streamflow accurately in real-time using the TF model, it is not only necessary to determine accurate structure of the model but also required to reduce forecasting error in early stage. In this study, after introducing 5-day Antecedent Precipitation Index (API5), which represents the initial soil moisture condition of the watershed, by using the threshold concept, the TF models in each API5 are identified by Box-Jenkins method and the results are compared with each other.
