In removable dental prostheses, it is important to minimize impairment of residual tissue caused by wearing dentures. There are two factors that harm residual tissue. The first is functional load bearing of remaining teeth and alveolar ridges and the second is the effect of poor oral hygiene. Double crown retained removable dental prostheses provide rigid support, and it may reduce impairment caused by load bearing of alveolar ridges. Also, dental plaque and oral deposits, which are attached to outer crowns and dentures, can be easily managed extra-orally. In addition, it is beneficial to the health of the marginal gingiva because inner crowns have easy access for oral hygiene. In this case, double crown retained removable dental prostheses were used for the partially edentulous patient with severe residual alveolar bone resorption and poor oral hygiene, and the result was clinically satisfactory in terms of functional, esthetical, and oral hygiene aspects.

Purpose: Nurses' management of Nursing Home residents' remaining functional ability is phenomena emphasizing as the main practice focus in long term care and has specific meanings within the context of quality of life for fragile and disabled elderly people in nursing homes. This study was conducted to clarify and to conceptualize the phenomena of nurses' management of nursing home residents' remaining functional ability. Method: The Hybrid Model of concept development was applied to develop a concept of nurses' management of residents' remaining functional ability. Results: This concept of nurse' management emerged as a phenomenon having meanings in two different dimensions, deliberation and enactment for five types of residents: residents with declining function and dementia requiring nursing assistance, bed-ridden residents with moderate dementia, residents with advanced dementia and behavior problems, but good physical health, residents at the end of life stage, and bed-ridden residents with intact mental health. Conclusions: Results indicate that nurses' management of remaining functional ability of residents in nursing homes is a concept having types of needs that should be treated in specified ways. Interventions should have a positive impacts on practical applications in nursing homes and on enhancing residents' remaining function.

This study develops the process and method of official administration documents which have remained ill-balanced like the official documents of the government-general of Chosun(the pro-Japanese colonial government (1910-1945)). At first, the existing Appraisal-theories are recomposed. The Appraisal-Theories of Schellenberg is focused valuation about value of records itself, but fuction-Appraisal theory is attached importance to operational activities which take the record into action. But given that the record is a re-presentation of operational activities, the both are the same on the philosophy aspect. Therefore, in the case that the process - method is properly designed, it can be possible to use a composite type between operational activities and records. Also, a method of the Curve has its strong points in the macro and balanced aspect while the Absolute has it's strength in the micro aspect, so that chances are that both alternate methodologies are applied to the study. Hereby, the existing Appraisal theories are concluded to be the mutually-complemented things that can be easily put together into various forms according to the characteristics of an object and its situation, in the terms of the specific Appraisal methodology. Especially, in the case of this article dealing with the imbalance remains official-documents, it is necessary to compromise more properly process with a indicated useful method than establishing a method and process by choosing the only one theory. In order to appraise the official-documents of the pro-Japanese colonial government (1910-1945), a macro appraisal of value has to be appraised about them by understanding a system, functions and using the historical-cultural evolution, after analysing Disposal Authority. From this, map the record so that organization function maps are constructed regarding the value rank of functions and detailed-functions. After this, establish the appraisal strategy considering the internal environment of archival agencies and based on micro appraisal to a great quantity of records remained and supplying other meaning to a small quantity of records remained for example, the oral resources production are accomplished. The study has not yet reached the following aspects ; a function analysis, historical decoding techniques, a curve valuation of the record, the official gazette of the government general of Chosun( the pro-Japanese government for 1910-1945), an analysis method of the other historical materials and it's process, presentation of appraisal output image. As the result, that's just simply a proposal and we should fill in the above-mentioned shortages of the study through development of all the up-coming studies.

The aim of this study was to investigate the relationship between the oral health status of elderly under visiting health care and their oral health-related quality of life. The subjects were 300 elderly under visiting health care program over 65 years old in Asan city and they were interviewed. The result showed that average Geriatric Oral Health Assessment Index (GOHAI) score was 37.36 and the lowest scored question was 'never satisfied with the oral condition'. In GOHAI related to oral health behaviors, unmet dental treatment experience was statistically significant (p<0.001). In overall GOHAI, number of remaining teeth (p<0.001) and the age had statistical significance and men had higher score in pain and discomfort (p<0.05), under age of 74 limited function factors score was high (p<0.01). The number of remaining teeth had statistical significances in most factors except pain and discomfort (p<0.001). The factors affecting GOHAI were age (p<0.05), number of remaining teeth (p<0.001) and perceived health state (p<0.001). In order to improve oral health-related quality of life of elderly receiving visiting oral health care services, it is necessary to increase denture support by securing budgets and developing oral health promotion programs at the local government level.

Channel-type lining board(CLB) is a welded steel structure used in the field of open cut subway excavation and building basement construction. Lining board is generally installed at the underground environment which is exposed to corrosion factors such as humidity, temperature and corrosive gases. This study evaluates reusability of the corroded lining board by experimental and analytical method. Static loading tests were performed to know serviceability of corroded CLB after checking thickness loss of the used CLB parts. Strain of the plates and middle point deflection was measured simultaneously. According to experimental test results and comparison with numerical analysis, the thickness loss of the plates by corrosion makes more vertical displacements and stresses in members under the DB vehicle load considering impact factor. As a result, this paper is proposed a way to evaluate used and corroded CLB by checking the plates thickness and it makes construction engineers easy to know optimal time to replace their old CLBs with new one.

The residual alveolar ridge below the denture base undergoes physiologic changes over time, which results in the existing dentures becoming less accurate with the residual alveolar ridge. In addition, changes of the occlusal plane, decreasing in vertical dimension and loss of denture retention and facial support can occur. Consequently, denture relining may be required to accommodate these changes and ensure an ongoing close fit. Relining a denture can be performed directly on the chairside using autopolymerizing relining materials or indirectly in the laboratory using heat-cured relining materials. A direct relining method is not only simple but also time and cost effective. However, irritation or burning sensation of the mucosa can occur, and poor bonding of the relining material to the denture base can be cited as disadvantages. The indirect relining method exhibits relatively high bonding strength between the relining material and the denture base, but the patient might experience discomfort during relining process period. This report will examine the characteristics of relining materials, including those used in the relining of CAD-CAM dentures, and explore the clinical considerations for relining procedures.

The Administration of Labor was responsible for the technical and practical functions like policy-making of labor matters and implementing the relevant laws. However, there has been a few record transferred to the National Archives to help find out the labor policy-making process. This is one of the typical examples that shows the discontinuity and unbalance, and disorderly filing of the administrative records in Korea. Naturally it is almost impossible to retrieve the appropriate content through the records file-name. Users should be at the trouble to compare the record items and their content one by one. For the re-organization of the Administration of Labor' records, this research suggests the four-level analysis of functions of the Administration. The Administration of Labor' survived records could be linked to each level function. And the publication of the 'Records Abstract Catalog' providing users with more information about the records would pave the way for easier access to the records. In addition, it also suggests the logical re-filing of the survived records of which we cannot find the order or sequence. This re-organization of the survived records would help to establish the acquisition and appraisal policy of the labor records as well as the new way of description and finding tool hereafter. Drawing up labor history map is a starting point for the acquisition strategy of the labor records, which could allow users to gain systematic access on the survived records. Of course, extensive investigation and research on the survived records is a prerequisite for the map. It would be required to research on the survived records of the other government agencies, including economic-social area ministries and investigation agencies and the National Assembly as well. It is also needed to arrange and typify the significant incidents and activities on thematic and periodic frames in the labor history. If possible to understand or connect the survived records and these accomplishments comprehensively, it would be of great help for the acquisition of the labor records and the related oral records projects.

다목적댐 하류하천은 댐 건설당시 정비가 필요한 지역으로 댐 방류의 영향을 받는 일정구간에 대해서는 댐설계방류량에 대응하도록 하천정비가 시행되어야 하나, 지금까지의 댐 하류하천은 댐과 별개로 하천정비가 시행되어 왔으며, 관리 또한 댐과 이원화되어 이루어져 왔다. 이로 인해 댐하류하천은 제방월류, 하천구역내 사유지 및 불법시설물 등의 댐운영 제약사항으로 댐 본래의 치수기능이 저하되어 한국수자원공사에서 관리중인 15개 다목적댐 여수로 방류가 설계방류량의 16%(15개 다목적댐 전체 여수로 설계방류량 $57,004m^3/s$ ${\rightarrow}$ 무피해방류량 $9,300m^3/s$)에 불과하고, 대규모 홍수 발생시 댐하류지역에서 막대한 피해와 민원을 발생시키고 있다. 이러한 댐운영 제약사항해소를 위해 한국수자원공사에서는 '07년부터 연차별로 소양강댐을 포함한 22개댐 하류하천의 정비를 시행하고 있다. 현재 시행중인 용담댐 하류하천정비를 시행사례를 통해 댐운영 제약사항해소와 이에 따른 댐의 치수기능 회복효과를 분석해보면 다음과 같다. 댐방류시 현장조사를 통해 확인된 댐운영 제약사항은 하천구역내 사유지를 포함해하여 총 8건이며, 구조적 대책인 제방 축조와 비구조적 대책인 사유지 보상 등을 통해 댐 무피해방류량을 현재 $700m^3/s$ (여수로 설계방류량 대비 22%)에서 $2,730m^3/s$(여수로 설계방류량 대비 85%)로 증가 방류 할 수있는 것으로 분석되었다. 그러나, 구조적 비구조적 대책으로 불가능한 하천구역내 불법 경작지 및 시설물 등이 일부 잔존하여 댐운영 제약사항으로 여전히 남아 있는 실정이다. 이러한 문제를 해소하기 위해서는 불법행위에 대한 관리감독 강화 등의 조치가 필요하나, 이원화된 현행 관리체계에서는 한계가 있으며, 이와 같은 문제를 해소하기 위해서는 댐 방류의 영향을 받는 하류하천 일정구간에 대해서는 댐관리자의 역할 강화가 필요하다.

Prognostics and health management(PHM) is actively utilized by industry as an essential technology focusing on accurately monitoring the health state of a system and predicting the remaining useful life(RUL). An effective PHM is expected to reduce maintenance costs as well as improve safety of system by preventing failure in advance. With these advantages, PHM can be applied to the battery system which is a core element to provide electricity for devices with mobility, since battery faults could lead to operational downtime, performance degradation, and even catastrophic loss of human life by unexpected explosion due to non-linear characteristics of battery. In this paper we mainly review a recent progress on various models for predicting RUL of battery with high accuracy satisfying the given confidence interval level. Moreover, performance evaluation metrics for battery prognostics are presented in detail to show the strength of these metrics compared to the traditional ones used in the existing forecasting applications.

최근 급속한 도시의 팽창 및 신도시 건설과 산업의 발전으로 가스시설은 꾸준히 확대되고 있는 실정이다. 그리고 94년 아현동 도시가스사고와 95년 대구 도시가스사고 이후로 도시 가스 시설물의 대한 안전 대책 및 시설물 관리에 대한 국민들의 관심이 증대되었다. 이러한 흐름에 따라 가스회사들은 GIS 기술을 도입하여 기존에 수작업으로 관리되고 있는 가스시설 정보체계를 전산화하여 항상 최신의 현황을 유지하고, 사고 발생시 신속한 대처 방안 및 피해예측을 위한 시스템을 개발하기 위하여 많은 연구를 진행하고 있는 실정이다. 본 연구의 목적은 안전이 중요시되는 가스시설물에 대하여 가스사고 발생시 신속한 대처 및 처리방안을 제시할 수 있는 GIS 기반의 가스사고 관리시스템을 개발하는데 있다. GIS의 가스사고 관리시스템에서는 사고 발생시에 시설물 관리자가 사고 지점을 선택하여 우선적으로 공급을 중단해야 할 관로를 제시하고 사고지점을 검색하여 차단해야 할 밸브에 대한 정보를 신속히 제공하여 대응 방안을 제시 할 수 있도록 하였다. 아울러 가스공급이 중단되는 지역에 대한 정보를 추출하여 피해범위를 산정하여 효율적인 사고 관리를 지원하도록 구성되었으며, 이와 함께 잔존가스량을 구하여 사고후의 대처방안을 마련할 수 있는 기능을 제공하도록 하였다. 향후 연구과제로는 원격으로 가스 시설물을 감시하고 제어할 수 있는 원격감시/제어시스템(SCADA System)과 연계를 통하여 가스사고 후에 신속한 피해예측 및 피해를 최소화 할 수 있는 방안제시 및 GPS를 활용하여 신속한 사고처리를 할 수 있는 활용 방안을 연구하여 체계적이고 종합적인 가스사고의 관리가 필요하다고 사료된다. 또한, 사고 후의 긴급 대처방안 뿐만 아니라 잔존가스량을 이용하여 수용가에 가스의 신속한 재공급을 위한 정보의 제공까지 한 단계 발전된 시스템의 개발이 추진되어야 한다.남산지역에 대해 정사영상과 10m간격의 DEM을 제작하였으며 1:1000 수치지도를 통해 제작된 DEM과 비교한 결과 총 43990개 격자점의 표고 차이는 평균 5.98m였다.여재 높이 100 cm에서 원수를 하향류 및 상향류로 주입하면서 하향류 20, 40, 80, 100 cm, 상향류 20, 40, 60, 80, 100 cm에서 시료를 채취하여 분석한 결과 모두 원수가 주입되는 부근 여재 높이 20 cm에서 가장 많이 제거되었다. 상향류 보다 하향류로 원수를 주입했을 때 제거효율이 높았다. $Fe^{+++}$을 $Fe^{++}$로 환원하는 $O^{-}_{2}{\cdot}$의 작용을 대신할 수 있음을 증명하며 이와같은 ascorbate 의존적인 $OH{\cdot}$ 의 생성은 ascorbate가 조직손상에 관여할 가능성을 시사하였다.었다. 정확한 예측치를 얻기 위하여 불균질 조직이 조사야에 포함되는 경우 보정이 요구되며, 골반의 경우 골 조직의 보정이 중요한 요인임을 알 수 있었다. 이를 위하여 불균질 조직에 대한 정확한 정보가 요구되며, 이는 CT 영상을 이용하는 것이 크게 도움이 되리라 생각된다.전시 슬러지층과 상등액의 온도차를 측정하여 대사열량의 발생량을 측정하고 슬러지의 활성을 측정할 수 있는 방법을 개발하였다.enin과 Rhaponticin의 작용(作用)에 의(依)한 것이며, 이는 한의학(韓醫學) 방제(方劑) 원리(原理)인 군신좌사(君臣佐使) 이론(理論)에서 군약(君藥)이 주증(主症)에 주(主)로 작용(作用)하는 약물(藥物)이라는 것을 밝혀주는 것이라고 사료(思料)된다.일전 $13.447\;{\mu}g/hr/g$, 섭취 7일중 $8.123\;{\mu}g/hr/g$, 절식 14일후 $10.612
