The purpose of this study is to evaluate efficiency by the Life Cycle Cost(LCC) analysis of floor covering materials for remodeling. This study has been performed as a case study. The LCC analysis is a technique which takes account into both initial-future costs and benefits of an investment over some period of time. LCC is important in commercial decision making because it provides improved assessment of the living-term cost effectiveness of construction projects as well as alternative economic methods that focus on initial costs. For LCC analysis and comparison, the present value technique is used. The results of this study are summarized as follows; (1) A LCC analysis model of floor covering materials is suggested through a case study (2) As a result of LCC case study, the type of sheet is analysed more economical than that of tile in floor covering materials.

Much effort has been made in the radiometric calibration of the ocean scanning multispectral imager (OSMI) since after the successful launch of KOMPSAT-1 in 1999. A series of calibration coefficients for OSMI detectors were obtained in collaboration with the NASA Sensor Intercomparison and Merger for Biological and Interdisciplinary (SIMBIOS) project office. In this study, we ompare the OSMI level-2 products (e.g., chorophyll-a concentration) calculated from the NASA cross-calibration coefficients with the SeaWiFS counterparts. Sample study areas are some of diagonostic data sites recommended by the SIMBIOS working group. Results of this study show that the OSMl-derived chlorophyll-a concentration agrees well with the SeaWiFS counterpart in Case 1 water; however, differences become larger in Case 2 water.

In Korea, construction and development has been continued rapidly since the 1970s, and the reconstruction and renovation market has recently been activated to improve old buildings. Most of the environmental evaluation of reconstruction and renovation projects is focused on the use of operating energy, and It is necessary to analyze carbon emissions throughout the life cycle for a comprehensive evaluation of reconstruction and remodeling projects. Therefore, this study quantitatively predicted carbon emissions from reconstruction and renovation based on ISO 14040s through case analysis for the purpose of evaluating the carbon emissions of renovated buildings from the perspective of the whole life cycle. In additional, the amount of carbon savings of each was analyzed through comparison with existing building.

본 연구에서는 현장잔토를 활용할 수 있고 다짐이 불필요하여 관로공사에 유용한 경량기포혼합토를 지중매설관의 뒷채움재로 이용할 경우 관로의 거동을 조사하기 위하여 시험시공을 실시하고 계측결과를 분석하였다. 동시에 동일한 조건의 새만금 준설토사 뒷채움 시공결과와 비교하였다. 연직토압의 경우 경량기포혼합토 뒷채움 시 준설토사 대비 초기 슬러리 상태에서 25.6% 가량 저감되었고 양생 후에는 준설토사 토압의 10% 이내에 불과하였다. 준설토사 뒷채움 시에는 경량기포혼합토 대비 수평토압의 경우 3.6배 이상, 연직 및 수평변위는 각각 3.2배와 2.6배 가량의 차이를 나타내어 경량기포혼합토의 토압 및 변위저감 효과가 우수한 것으로 나타났다. 매설관 상반부에서 측정된 응력의 경우 토사 뒷채움 시 대체로 압축응력이 발생한 반면, 경량기포혼합토를 타설한 경우 초기 슬러리 상태에서 발생한 부력으로 인하여 고정된 양단부를 지점으로 부(-)의 모멘트가 발생함으로써 상반부에 인장응력이 발생하는 결과를 얻었다. 결론적으로, 새만금에서 준설된 토사를 이용한 경량기포혼합토는 인근 개발지에서 매설관 뒷채움재로 활용하는데 있어 준설토사와 비교하여 매우 우수한 재료이나 타설 시 부력에 대한 대책이 필요하다.

RESULTS : According to results of analyses, In case of standard design compressive strength of concrete is 18MPa, 21MPa, similar reliability of RILEM equation were 0.89~0.90, but in case of standard design compressive strength of concrete is 35MPa, 40MPa were 0.4~0.56. According to standard design compressive strength of concrete is 40MPa, similar reliability of ultrasonic pulse velocity method equation were 0.56. CONCLUSIONS :RILEM equation had high similar reliability than other equation in case of standard design compressive strength of concrete is 18MPa, 21MPa, but had low similar reliability than other equation in case of standard design compressive strength of concrete is 35MPa, 40MPa. and ultrasonic pulse velocity method equation had low similar reliability than other equation in case of standard design compressive strength of concrete is 40MPa.

Background: The purpose of this study is to identify effects of neuro-muscular control training on vastus medialis oblique (VMO) after menisectomy of the knee. Methods: The subjects of this study are women aged 42 and 39 each who did menisectomy. Case 1 was applied quadriceps setting exercise and neuro-muscular contrlol training and case 2 was applied quadriecps setting. Intervention was done 5 times a week for 2 weeks. Measurement of muscle activity on VMO and vastus lateralis (VL) was standardized signals of each muscle to %RVC using surface EMG. Results: On comparison of exercise before and after on VMO and VL, VL activation of case 2 was increased more than case 1. Conclusion: Quadriecps-setting exercise and selective neuro-muscular control training of VMO is effective intervention on VMO activity and muscle activity ratio of VMO to VL.

Purpose: The aim of this study was to evaluate the effects of tailored case management using a gatekeeper on depression and life satisfaction in the single-household elderly population. Methods: The design of Quasi experiment was applied to compare the variables before and after the management. Ninety-seven people who had depression categorized by the Korean Geriatric Depression Scale. Results: Depression (t=11.22, p<.001) and life satisfaction (t=-5.36, p<.001) were improved after management in comparison to the results of pre-tests, and the differences were statistically significant. The difference in the pre-test and post-test scores of the support system ($x^2$=13.89, p<.001) were significant, while the differences in the perception of depression ($x^2$=.02, p=.891) and coping methods ($x^2$=.34, p=.558) were not statistically significant. Conclusion: Tailored case management using a gatekeeper is effective to reduce the degree of depression and improve life satisfaction in the single-household elderly population having depression. This study offers a model of individualized as well as systemic mental health care for the community of single-house hold elderly people as an effective means for prevention of and early intervention in depression.

So-called sclerosing hemangioma of the lung is a rare benign neoplasm which usually presents with a coin lesion detected through routine chest X-ray. We report two cases showing characteristic cytologic appearances which have been rarely reported. Both cases were young females with coin lesions in the lung. Fine needle aspiration of each case revealed unique but some different cytologic features. Case 1 showed bland-looking polygonal epithelial cells resembling bronchioloalveolar cells haying predominantly papillary configurations with loosely arranged solid sheets or isolated cells. Cytoplasms were plump, cyanophilic, and finely granular, with eccentric nuclei. The nuclei were usually monotonous, round-to-ovoid, and vesicular with a small but conspicuous nucleolus. In comparison to case 1, case 2 revealed largely loose pavement-like solid sheets or clusters rather than papillary patterns in the hemorrhagic background. The size of tumor cells were a little smaller than that of case 1. Bronchioloalveolar carcinoma and papillary adenocarcinoma of metastatic origin were considered to be one of the important differential diagnoses with these cytologic features. Histologically, both cases exhibited findings compatible with so-called sclerosing hemangioma of the lung.

This study, a new concept design of the stem and aims to determine the suitability of various carbon/PEEK composite designs for artificial hip joints. Shear stress tested with alternative materials of the Ti-based stem for artificial hip joints. In addition, FEA is conducted according to the fiber ply orientation and the load condition for carbon/PEEK composites. The stem shape of two types was designed through the shape normal of the femur. Multidirectional load cases were used for each FEA model. In the case of general shape, the results show that the stress of ply orientation case II was lower than for cases I and III. On the other hand, in the case of the curved shape, ply orientation case I was lowest. In the case of the Ti stem, the stress of the curved shape was 18% lower than the general shape.

본 연구의 목적은 복합하고 다양한 문제를 가지고 있는 재가노인의 욕구충족을 위해 사례관리 서비스를 제공하고 그 효과성을 검증하는데 있다. 본 연구에서 사용한 사례관리모델은 팀접근 모델이며, 이는 사례관리팀을 이루어 그 안에서 수퍼비전을 제공하고, 인력활용이 이루어지는 형태이다. 수퍼비전은 지역 사회 내에서 활동하는 전문가들로 조직된 팀에서 제공하고, 서비스는 주요사례관리자와 준전문가로 구성된 활동가팀에서 담당하였다. 준전문가는 1주일에 한 번 노인클라이언트의 가정에 방문하여 노인의 상황을 모니터링 하였으며, 주요사례관리자는 상담 제공과 지역사회 자원을 연결하였다. 비동일 통제집단설계를 사용해 6개월간 제공된 팀접근 사례관리 서비스의 효과성을 검증하였는데, 사용된 도구는 삶의 질과 삶의 만족도였다. 실험집단 노인 30명에게 사례관리 서비스를 실시한 결과 삶의 질과 삶의 만족도는 부분적으로 사전사후 점수간에 유의미한 차이를 보여 팀접근 사례관리 서비스의 효과성이 입증되었다. 비교집단의 노인 28명은 일상적인 재가복지서비스를 받게 하였으며, 사전사후 점수간에 유의미한 차이가 나타나지 않아 팀접근 사례관리 서비스는 효과적인 것으로 나타났다.
