This study investigates a neotectonic context of the past 5 Ma for the Otway Ranges along the southern Victoria coast, SE Australia by evaluating the distribution and development of marine terraces along the mountainous coastal area. Uplift rate derived from low terrace deposits using OSL dating method is determined to evaluate the extent to which mild intraplate tectonism has the capability to influence the geomorphic evolution of continental interiors. This study also investigates the stratigraphic relationship between Quaternary marine terraces and Pliocene strandlines, which suggests a change of tectonic activity in the Late Neogene. The intensified tectonic response is well addressed in terms of an increase of the Australian intraplate stress level due to the change of relative motion and increased forces in the boundary between the Australian and Pacific plate.

It is generally known that a two-lane roundabout has some problems in safety such as increasing conflicts, typically merging and diverging conflicts and conflicts between entering traffic and exiting as well as turning traffic. To solve these problems, a turbo-roundabout had been developed and has successfully brought safer and more efficient operation in other countries. In this study, micro simulations using VISSIM were conducted to investigate the maximum value of service traffic volume. It was found that operation of turbo-roundabouts was influenced by traffic volume for each turning traffic, and the maximum values of traffic volume were values between 2,400 and 2,800 vehicles per hour as rates of traffic volume for each turning traffic. Typically, turbo-roundabouts have limited to operate in conditions with more than 30% for left-turning traffic volume.

The purpose of this article is to empirically testify three hypotheses on the relation between married women's employment and the allocation of unpaid domestic work within households - i.e., adaptive partnership (AP), dual burden (DB) and lagged adaptation (LA) models. The AP hypothesis assumes that, when wives are employed, husbands spend more time doing housework in order to compensate for their wives' increased responsibility. The DB model, by contrast, indicates that, even if married women are employed, their burden on domestic work does not decrease. In this case, therefore, the dual burden of married women can be expected. Between these two opposite views, the third, alternative hypothesis has been suggested recently. The LA model argues that the behaviours of households are adaptive to the changing environments but over a period of many years and even across generations. The article has analysed the total work time as well as unpaid domestic work time to testify these three hypotheses, utilising 1999 Time Use Survey data of the National Statistical Office. The research results can be summarised as follows. First, married working women worked 100 minutes more than their male spouses. Second, the average domestic work time of married men, 23-25 minutes per day, was no more than 5-10% of that of women. Third, the effects of age and women's employment were not statistically significant in multiple regression models, which means that the DB hypothesis explains the situation of married working women in Korea. Based on these findings, the article suggested the expansion of the public social service system to mitigate the dual burden of married working women, the introduction of compensatory credit for caring work, and the directions of further empirical research using the time use survey data.

For the purpose of better understanding of RAD children, comparisons were performed about the developmental and psychopathological characteristics between RAD and PDD children. Study subjects were the children between the ages 2 and 6. who visitied SNUCH Child and Adolescent Psychiatry OPD or treated in Day Treatment Center during May, 1989 and Sep., 1991, diagnosed by the child psychiatrist as RAD or PDD according to DSM-III-R diagnostic criteria. A total of 40 children were included in the study. 20 were RAD(18 boys, 2 girls). 20 were PDD(20 boys). PEP was performed to all study subjects, by the raters blind to psychiatric diagnosis of each. And analysis was done about the level of developmental functioning score and psychopathological scores between RAD and PDD children. The results are as follows 'There were retardation on the general developmental functioning in RAD children, and the severity of retardation were lined up as perceptual ability>imitation>gross motor>cogitive language>eye-hand coordination>fine motor. Characteristics of psychopathology in RAD children were lined up by severity as language>play>relationship>affection >sensory. Group differences of the two shows on PDD group rejection score was significantly higher on the perception item. while RAD was superior on the perception emerging response. Differences of the psychopathology between two groups were on such areas as ; Affection, which was significantly higher on 'Absent' in RAD, while significantly higher on 'severe' in PDD children. On the interest for the play and materials. sensory and language areas, RAD children were significantly higher ratings on 'Absent' than PDD children.

To investigate determinants of health care utilization of the physically disabled over 20 years old in age living in Taegu city, a self-administered questionnaire survey was carried out for 337 disabled persons with chronic illness from April to July, 1997. Health care utilization .ate was 81.9%(69.1% for hospital or clinic and 12.8% for pharmacy). Marital status, job, health concern, and response to illness showed statistically significant relationship with health care utilization(p<0.05). By path analysis, job, economic status, medical security type and response to illness had a significant direct effect on health care utilization(p<0.05), however, health concern and regular source of care had an indirect effect. The reasons of no health utilization were due to economic problem(31.1%), no symptom(18.0%), inconvenience to seek care or no accompanying persons to be helped(14.8%), unseriousness of the severity of the illness(14.8%), too busy to be treated or no free time(8.2%), hopeless prognosis to be treated(6.6%) in order. In conclusion, it is recommended that the program for expanding medicaid, improving socioeconomic status by getting a job and health education to increase the health concern toward physically disabled should be implemented to increase health care utilization rate.

Paleomagnetic studies have made remarkable contributions to the understanding of many geological aspects of Korea for the last 40 years, such as the collisional processes of Korean Peninsula, the development of basins in relation with fault systems, the opening and evolution of the East Sea, and the reconstruction of paleogeographic configuration. These contributions have played an important role in the escalation of geology in Korea by elucidating the mechanisms on Processes of fragmentation and amalgamation of the Peninsula, mountain building, igneous activities, metamorphism, and folding and faulting based on the view of plate tectonics. This paper is intended to introduce and summarize the paleomagnetic research papers designed to decipher the tectonic processes of Korea, according to the geologic ages of the studied rocks.

유비쿼터스 시대의 도래에 따른 서비스의 고급화는 다양한 형태의 사용자 단말기의 개발을 유도 하였으며, 이러한 사용자 단말기의 변화는 다양한 형태의 인간친화형 사용자 인터페이스의 개발로 이어지게 되었다. 이러한 다양한 형태의 인간친화형 사용자 인터페이스 중, 인간의 뇌를 활용한 사용자 인터페이스, 즉 BCI에 관한 연구가 산발적으로 다양하게 진행되고 있다. 현재 진행되어지고 있는 다양한 형태의 BCI관련 연구들은, 연구 초기 수준을 극복하지 못하는 실정이며, 이러한 연구 개발의 지체 이유로는 DB구축부터 시작한 체계적인 연구가 이루어지고 있지 않는 점을 들 수 있다. 또한, 뇌파 신호의 수집 시 효율적인 피험자 지침 관련 연구가 없는 실정이며 기 구현되어진 대부분의 시스템이 로컬시스템 형태로 구성되어져 DB 구축 시 한정적인 피험자 수, 대용량의 뇌파 DB수집 시 한계, 뇌파 DB의 신뢰성이 저하되는 문제점을 야기한다. 본 논문에서는 이러한 문제점을 극복하기 위하여 VoiceXML을 활용한 온라인 기반의 DB구축 시스템 구현을 제안 하며 신뢰성 및 객관성을 확보 하고자 한다.

구간검지체계를 기반으로 한 첨단교통정보제공시스템(Advanced Traveler Information Systems)은 그 기능 수행시 다음의 중요 고려사항을 지닌다. 첫째는 제공 정보의 신뢰성이며, 둘째는 정보수집비용에 관련한 수집자료수의 한계이다. 본 논문에서는 이러한 한계성 극복을 위해 보다 대표성 있는 교통정보 형태의 설정 및 통계적으로 신뢰성 있는 정보산출을 위해 요구되는 적정표본수의 결정에 대한 연구를 수행하였다. 도시고속도로(올림픽대로)와 도시간선도로(천호대로)의 실측 구간통행시간분포 분석결과 단일교차로 구간의 경우 다른 구간들의 단일봉(unimodal)의 정규분포형태와는 다른 두 개의 봉우리를 지닌 분포형태(bimodal)가 나타났다. 따라서 이러한 구간은 기존과는 다른 새로운 교통정보 형태가 필요하며, 본 논문에서는 모든 통과차량들의 평균통행시간으로 정의되는 한 개의 대표치가 아닌 신호주기에 의한 정지여부에 따라 분리되는 주행시간과 지체시간 또는 주행속도와 통행속도 개념의 세분화된 정보형태를 설정하였다. 또한 중심극한정리를 기초로 한 통계적인 표본수 결정식을 이용하여 설정된 신뢰수준 하에서의 정보산출을 위해 요구되는 적정 표본수를 산출하였다. 그 결과, 교통이 혼잡할수록 요구되는 표본수는 적어지는 것으로 나타났다. 우선 적정 표본수 만큼의 표본추출을 하고 제안된 정보산출 방법에 의해 교통정보를 산출한 후 실측치와의 오차를 비교하였다. 그 결과 산출된 교통정보는 신뢰수준 95%와 허용오차 5㎞/h를 만족하였다. 다음으로 구간검지체계를 이용하여 정보를 산출하는 타시스템 교통정보와의 오차율을 비교하였다. 그 결과, 실측치와 본 연구의 산출방법에 의한 교통정보, 로티스교통정보 및 차량번호판 인식시스템의 교통정보와의 비교 결과 제안된 교통정보형태의 타당성을 볼 수 있었다.
