When a nail pulled out in dense, granular soil, the soil in the vicinity of the nail tends to dilate, but its dilatancy results in a normal stress concentration at the soil/nail interface, thereby increasing the pull-out resistance of the inclusion. It is thought to be occurring within the resistance zone where the soil mass is at stationary state and the reinforcement are held in position by the soil, due to the friction or bond. In this paper, A series of direct shear and interface tests were conducted by using so called‘Constant Normal Stiffness Test Apparatus’which was modified and improved from the conventional direct shear box test rig. Unlikely the normal shear box test, this enables to simulate the different constraint effects of surrounding soil during shear under the conditions of constant stress and volume, constant normal stiffness. The aim of the research programme is to get better understanding of pull-out bond mechanism, thus to explore the possibility of evaluating the pull-out bond capacity of soil/reinforcement at the preliminary design stage from the laboratory test.

Purpose: The purpose of this study was to survey the present status of the gerontological nursing course in Baccalaureate degree programs(BSN) in Korea, so as to provide basic data for developing a standard model for a gerontological nursing curriculum. Method: Data on the contents of a gerontological nursing curriculum was collected from those programs that had a gerontological nursing course. Result: The results show that 48 schools(87.3%) offered a gerontological nursing course. Twenty-five schools(45.5%) had both lectures and clinical practicum, while 23 schools(41.8%) had only lectures. Twenty-seven schools(56%) offered a gerontological nursing course as an elective. Students earned the most number of credits in their senior year. The most common credit system for lecture subjects was 2 credits with 38 schools(79.2%) and a clinical practicum was 1 credit with 20 schools(80%). The issues identified were that gerontological nursing was an elective and not a mandatory course, a lack of clinical lab hours, and a lack of common learning objectives. Conclusion: Recommendations are made for better defined curricula in gerontological nursing. In addition, further investigations of the learners or students entering gerontological nursing to facilitate curriculum development and appropriate instructional strategies are needed.

This study is intended for bedding stores and finds management performance factors from providers' aspect. Henceforth this study can be used when bedding stores were considered to establish by determinations and bedding companies with statistics as a criterion and a tool so that make an accurate estimate. First, it was found that location and trade area are the most influential factor in the management performance. Second, the result of study showed that location placed first in the importance of management performance factors in bedding stores, consumer came second, followed by competition. Third, it was assumed that the large floating population around the bedding store was the most important variable in location factor, the large resident population was the most important one in the consumer factor and high quality product was the most important one in the economic factor.

Recently, there have been many attempts to monitor the equipment's condition or the input devices in sensors remotely by using cable and wireless communications. Also, the research and development on this matter has been actively carried on. In this paper, we developed the monitoring system which will eliminate the errors of manual reading by humans and therefore will secure reliability between tenants and the building management office. Through the system, the private telecommunication network can be connected between the building management office and the households. This enables the control office to remotely read the electric meter and exact energy consumption of each household even when the tenants are absent.

It is difficult to accurately predict each flow rate of landfill gas and leachate extracted from many of wells, which have been completed into a waste landfill containing gas and water. However it may be approximately predicted if we can define only relative fluid permeability of gas and leachate flowing through landfill porous media. Therefore numerical simulation using multi-phase flow equations makes use of ei s input data of the relative permeability which is measured and calculated in laboratory environment like in-situ, and consequently we can quantitatively obtain each flow rate of gas and leachate from collection wells. These series of technologies can provide with the important informations to determine the success or failure of landfill gas energy and landfill stabilization. This paper analyses the characteristics of landfill gas collection by six classes of case studies for none described landfill.

본 논문은 시장개설 초기 4개월간의 주가지수 선물수익률과 기초자산인 현물(KOSPI 200) 수익률간의 선도-지연효과를 두 개의 모형을 이용하여 실증검증하였다. 첫 번째 모형은 설명 변수로 선물수익률의 시차변수를 사용하고 종속변수로 현물수익률을 사용했다. 두 번째 모형은 설명변수로 선물수익률의 시차변수를 사용하는 것은 첫 번째 모형과 같으나 종속변수로 ARMA모형에서 구한 현물수익률의 오차항(return innovations)을 사용하였다. 또, 여러 시장조건에서 현물수익률과 선물수익률사이의 선도-지연효과가 특정한 양상을 보이는가를 분석하였다. 좋은 정보와 나쁜 정보, 거래량이 많은 경우와 적은 경우, 변동성이 높은 경우와 낮은 경우로 나누어서 선도-지연효과를 살펴보았다. 실증검증의 결과 KOSPI 200 현물수익률은 ARMA(2,3) 모형이 적합하며 선물이 현물을 10분 이내로 선도한다. 하지만 그 관계는 일방적인 것이 아니어서 15분후에는 현물이 선물을 선도하는 피드백(feed-back) 현상이 나타났다. 좋은 정보(good news)에서는 선물이 현물을 5분정도 선도하고 나쁜 정보(bad news)하에서는 선물 선도현상이 약해진다. 보통 정보(morderate news)하에서는 현물이 선물을 10분내로 선도한다. 거래량이 많은 경우와 변동성이 높은 경우에는 선물이 현물을 선도하는 것이 뚜렷하나 거래량이 적은 경우와 변동성이 낮은 경우에는 선물과 현물간에는 특정한 선도-지연현상이 나타나지 않는다.

From Jan. 1 2009 to Mar. 31 2009, a study surveyed 295 national clinic medical institutions that was newly enrolled in Health Insurance Review and Assessment Service to identify the factors depending on whether the administrative personnel influences on the management of the clinic medical institutions. The survey showed that the medical institutions with administrative personnels affected more adjustments than those without administrative personnels and it appeared to be statistically significant except one time(p<0.01). The result of the survey tells whether the administrative personnel is or not in medical institutions has important effects on the reduction. So, it is considered that the placement of administrative specialists in the hospital is very important for medical institutions.
