현재의 도시의 설계 및 계획을 수행 하는데 있어 교통정보의 수집은 날로 그 중요성이 증대되고 있으나 현재의 도로변 매설 기반의 교통정보 수집방식으로는 국도나 신도시 예정 지구와 같은 예외의 상황에는 대처할 조사방법이 부족한 방법이며 이를 대처하기 위하여 주변지역의 데이터를 통해서 추정하는 방식을 사용하고 있다. 본 연구에서는 좀 더 나은 교통정보의 수집과 다양한 환경에서 조사가 가능할 수 있도록 DSRC와 레이더 검지기를 병합한 이동형 교통정보 수집기를 개발한다. 아울러 기존의 현장에서 단순한 데이터의 수집만을 수행하는 차원이 아닌 현장에서 수집된 데이터를 기반으로 분석이 가능한 시스템을 개발하였다. 개발된 시스템은 실제의 현장에서 테스트 되었으며 그 우수성을 검증하였다.

Purpose : To assess knowledge levels of cancer warning signs, a descriptive study wad conducted in Chungju rural area. Materials and Methods : We conducted a population-based study of men women who were 30 years of age or older, living in a three myens of Chungju rural area. Of 8,026 residents in 3 Myens, 1,148 adults(30 years of age or older) were completed structured questionnaire survey from July 21, 1997 to July 26, 1997. 7 cancer warning signs were used to assess knowledge level of cancer warning signs. Results : Participants in this study were poorly informed about the cancer warning signs, and the 24.9% of participants and divided by two groups. The high level group was 19.3%, and the low 80.7%. In this initial univariate analysis, the following variables were significantly associated with knowledge levels of cancer warning signs: age, sex, education, living with parter, annual income, smoking status, hepatitis vaccination, perceived possibility of cancer, previous cancer-screening examinations. In multivariate logistic analysis, we found three variables, sex, education level, previous pap-smear test, are significantly associated with knowledge levels of cancer warning signs. The knowledge level was higher among women, people with higher education, and those who had previous pap-smear examination. Conclusion : This study demonstrates that cancer warning signs are not common knowledge among the rural public. It also indicates the need for cancer education to improve knowledge in the rural public and the develop education programmes targeted especially at the old, men, and those who had not cancer screening examination should be considered to plan.

Opening wedge high tibial osteotomy (OWHTO) is widely used to treat unicompartmental osteoarthritis of the knee caused by degenerative deformations of the anatomical axes of the leg. However, since it is difficult to accurately plan the surgical degrees of adjustment such as coronal correction angle and tibial posterior slope angle to align the axes before the actual procedure, a number of studies have proposed analytical models to solve this problem. While previous analytical models for OWHTO were limited to specific cases, this study proposes an analytical osteotomy model (AOM) and a surgical planning system (SPS) that are suitable for a wide range of tibial morphologies and tibia conditions. The validity and generality of the model were verified in a total of 60 OWHTO cases. Results of the test showed that, as predicted, surgical degrees are affected quite significantly by tibia shape and slope of the resected surface. Comparison of the required surgical degrees and the degrees estimated from virtual surgery simulations using AOM showed a very small average difference of $0.118^{\circ}$. SPS, based on AOM, allows the operating surgeon to easily calculate surgical parameters needed to treat a patient.

As the patients who need to undergo liver transplant operation continues to grow. the number of livers that are donated can not keep pace with the demand. With the development of surgery skills, the necessity for operations from living donors is increasing. Nevertheless, satisfactory research has been conducted on the factors which generally affect the living donors. In this article. therefore. researchers focused on the factors which generally affect the donating liver donor in order to design a plan for recommending liver donation from living donors. The subjects were 91 living liver donors in C university hospital from October 1. 2000 to December 31. 2003. The results on the uncertainty of living donor, by test sheet. were analyzed with SAS program. The final results were as follows: 1. The uncertainty of the living donors was 51.54 marks per full credit 100. 2. The factor with the greatest effect on donation was the possibility of survival of the donor, followed by the admission period. marriage status and age. In recommending the living donation, the rate of donor survival after the operation was 5.2 times higher than death, 5.2 times higher when the admission period was under 20 days. 5.0 times higher when married. and 27.3 times higher when the family-related donation was very active at the age of 20s than in the 50s. These results suggest that all medical staffs should care for living donors with more interest and activity to give them the least complaints in admission and the lowest possibilities for complication. To enhance the survival rate and improve the surgical success rate. on-going monitoring should include regular health-checks. and continual efforts and education should be made to care for the health condition of the living donors after donation.

The purpose of this research was to reduce the burden of household management and the difficulty of rearing children, which are two most important obstacles for a dual-income family. For this, we suggested a cohousing project, as an alternative concept to conventional housing, where people can socially interact with each other and share mutual cooperation for a better quality of life. We surveyed the lifestyle of dual-income families in Korea, how they understood the cohousing project and their opinions on it. We carried out a survey with the wives from dual income families who were living in the metropolitan areas including Seoul. We contacted 30 wives for the survey to determine the reality of the double income couple family and interviewed them to make a detailed plan for cohousing based on their understanding and needs. In the results, many women who responded to the interview agreed that cohousing was an ideal housing arrangement for the dual-income family. However, they were anxious that it would take too much time and effort to develop their own housing estate by themselves. Therefore, we looked for a way to save time, efforts and cost in developing a cohousing project and came up with the remodeling as a solution.

Many ships in voyage experience weight and buoyancy distribution change by various reasons such as change of sea water density and waves, weather condition, and consumption of fuel, provisions, etc . The weight and buoyancy distribution change can bring the ships out of allowable trim, heeling angle. In these case, the ships should adjust trim and heeling angle by shifting of liquid cargo or ballasting, deballasting of ballast tanks for recovery of initial state or for a stable voyage. But, if the adjustment is performed incorrectly, ship's safety such as longitudinal strength, intact stability, propeller immersion, wide visibility, minimum forward draft cannot be secured correctly. So it is required that the adjustment of trim and heeling angle should be planned not by human operators but by optimization computer algorithm. To make an optimized plan to adjust trim and heeling angle guaranteeing the ship's safety and quickness of process, Uk! combined mechanical analysis and optimization algorithm. The candidate algorithms for the study were heuristic algorithm, meta-heuristic algorithm and uninformed searching algorithm. These are widely used in various kinds of optimization problems. Among them, heuristic algorithm $A^\ast$ was chosen for its optimality. The $A^\ast$ algorithm is then applied for the study. Three core elements of $A^\ast$ Algorithm consists of node, operator, evaluation function were modified and redefined. And we analyzed the $A^\ast$ algorithm by considering cooperation with loading instrument installed in most ships. Finally, the algorithm has been applied to tanker ship's various conditions such as Normal Ballast Condition, Homo Design Condition, Alternate Loading Condition, Also the test results are compared and discussed to confirm the efficiency and the usefulness of the methodology developed the system.

Korea Microlensing Telescope Network (KMTNet) is the first optical survey system of its kind in a way that three KMTNet observatories are longitudinally well-separated, and thus have the benefit of 24-hour continuous monitoring of the southern sky. The wide-field and round-the-clock operation capabilities of this network facility are ideal for survey and the physical characterization of small Solar System bodies. We obtain their orbits, absolute magnitudes (H), three dimensional shape models, spin periods and spin states, activity levels based on the time-series broadband photometry. Their approximate surface mineralogy is also identified using colors and band slopes. The automated observation scheduler, the data pipeline, the dedicated computing facility, related research activity and the team members are collectively called 'DEEP-South' (DEep Ecliptic Patrol of Southern sky). DEEP-South observation is being made during the off-season for exoplanet search, yet part of the telescope time is shared in the period between when the Galactic bulge rises early in the morning and sets early in the evening. We present here the observation mode, strategy, software, test runs, early results, and the future plan of DEEP-South.

Purposes: The purpose of this study was to identify the factors related to the long-stay hospitalization of dementia patients aged 65 years or older who had received inpatient care at geriatric hospitals according to the minute facility characteristics and patient features. Methodology: This study was conducted on 317,353 cases of 1,512 geriatric hospitals using the Health Insurance Review and Assessment Service dataset. The data collected were processed using the SAS Enterprise Guide 4.3 for descriptive statistics, the chi-square test, and the binary logistic regression analysis. Findings: As a result of the study, in the facility characteristics of geriatric hospitals, the long-stay hospitalization of the aged with dementia were found to be related to the type of facility establishment, the number of hospital beds, the number of medical specialists, the number of nursing personnel, and the number of geriatric hospitals by region and province. In the personal features of patients, the long-stay hospitalization was found to be associated with the gender, age, insurance, and the patient classification groups. Practical Implication: Considering the results of this study, it seems that securing the sufficient medical personnel in a geriatric facility, providing the good quality medical services, and preparing the appropriate discharge plan can reduce the unnecessary long-stay hospitalization and spend the medical expenses for the older patients.
