The Cases of advanced nations which have advanced welfare policy, they have headed for the deinstitutionalization and the protection of the local society. So they have expanded and improved the various policies and welfare facilities to be able to keep daily life on the base of local area. Many problems have been caused by rising the average life span of the elderly in Korea now. Under the tendency, there have been many alternative proposals to solve the problems. One of those proposals, the deinstitutionalization theory that is rated the ideal way, is the community-based care than the care in facilities for the elderly. It shows that the most ideal facility for the care is Daycare center and that it matters the system of spatial construction and standard of the facilities. Under the undetailed Korean standard of facility design, it is very important that system of spatial construction to correspond to the needs of the users and standard of the facilities are prepared from the point of view of the standard design of the domestic facilities for the elderly. The study of the book grasps the regional present situation of the domestic Daycare center and surveys the tendency of the stay and features of occupation of the user there through some case, and aims to have a thorough grip of the spatial scale by the user's behavior. It is to utilize for a proposal for preparation of the space scale, and an institution standard corresponding to user's needs in a Daycare center.

The tools that classify the severity of patients based on the prediction of mortality include APACHE, SAPS, and MPM. Theses tools rely crucially on the evaluation of patients' general clinical status on the first date of their admission to ICU. Nursing activities are one of the most crucial factors influencing on the quality of treatment that patients receive and one of the contributing factors for their prognosis and safety. The purpose of this study was to identify the goodness-of-fit of CPSCS of critical patient severity classification system(CPSCS) and Glasgow coma scale(GCS) and the clinical usefulness of its death rate prediction. Data were collected from the medical records of 187 neurological patients who were admitted to the ICU of C University Hospital. The data were analyzed through $x^2$ test, t-test, Mann-Whitney, Kruskal-Wallis, goodness-of-fit test, and ROC curve. In accordance with patients' general and clinical characteristics, patient mortality turned out to be statistically different depending on ICU stay, endotracheal intubation, central venous catheter, and severity by CPSCS. Homer-Lemeshow goodness-of-fit tests were CPSCS and GCS and the results of the discrimination test using the ROC curve were $CPSCS_0$, .734, $GCS_0$,.583, $CPSCS_{24}$,.734, $GCS_{24}$, .612, $CPSCS_{48}$,.591, $GCS_{48}$,.646, $CPSCS_{72}$,.622, and $GCS_{72}$,.623. Logistic regression analysis showed that each point on the CPSCS score signifies1.034 higher likelihood of dying. Applied to neurologically ill patients, early CPSCS scores can be regarded as a useful tool.

The goal of this study is to identify the new Architectural type of house and Landscape design pattern of the collective housing area in American garden city, Midlothian near Richmond of Virginia. I had been surveyed old houses of the Virginia and new single family houses and landscape design style of Mariners village to find a different style of houses and lots. The Richmond, capital city of Virginia, is surrounded by five suburban areas and counties. One of them is the Chesterfield where it has main street of Midlothian garden city. The city of Midlothian has a function of residence area both to stay in the forest garden and to go to downtown office of Richmond. There are a lot of collective housing area out of the capital city. I surveyed house form, lots, and site design pattern of the Mariners village in Midlothian. The community of Mariners shows a particular characteristics and harmonious pattern of suburban residence area in a view point of new project. There are three results of this study as follows: First, the types of house in suburban garden city, Midlothian, are focused on vernacular Colonial style with country house, traditional house, and front gable house form which are an unique new American single home. Second, the landscape design of this collective housing area, the Mariners village, has a unity view of residence community, harmony between house and lots, and a sensitive cul-de-sac pattern and loops type with rational land using based on the forest topology. Third, the Mariners village shows that the design concept of landscape architecture has to consider of traditionalism, naturalism, and living condition of residents.

Objectives: The purpose of the study is to investigate the subjective oral status perception and OHIP according to the oral health managementamong international and domestic university students. Methods: self-reported questionnaire was completed by 176 domestic and 175 international university students in Daegu and Gyeongbuk from August 25 to November 1, 2014. The informed consent was received after explanation of the purpose of the study by the researcher. The questionnaire consisted of general characteristics of the subjects, toothbrushing behavior, oral health management, subjective oral status perception. and oral health impact profile (OHIP). The subjective oral status perception and OHIP was measured by Likert 5 point scale. Results: The international students tended to have higher subjective oral status perception when they had longer stay with the roommate in Korea. The female international students tended to have higher OHIP than the male students. The domestic students with lower grades and roommates showed higher OHIP. The international students had a poorer practice of oral health management than domestic students. The overall mean of subjective oral status perception was 3.13 in domestic students, and 3.09 and 3.22 in international students. The overall mean of OHIP was 4.21 in domestic students and 4.25 and 4.16 in the international students, Conclusions: International students had a higher subjective oral status perception than domestic students, but their wrong oral health management lowered their quality of life. It is necessary to provide the oral health management for the international students continuously.

In this paper, a fuzzy inference control system is proposed for a turbojet engine with fuel flow control input only. The proposed control system provides a practical fuel flow control method to prevent surge or flame out during engine acceleration or deceleration. A fuzzy logic is designed to obtain the fast acceleration and deceleration of the engine under the condition that the operating point should stay between the surge line and flame out control line. With using both engine rotating speed error and surge margin as fuzzy input variables, the desired engine rotating speed can be achieved to rapidly follow the engine control line without engine stall. Computer simulation using the MATLAB is realized to prove the proposed control performance to the turbojet engine which is linear modelized using DYGABCD program package.

The purpose of this study was to investigate the contexts in which employed mothers with young children consider leaving the labor force. We used a mixed methods design, which integrates the findings of quantitative and qualitative analyses, to better understand the dynamics underlying employed mothers' intentions to leave the labor force. The participants of both quantitative (N = 324) and qualitative (N = 16) data were married mothers who were employed full-time and had at least one child younger than elementary-school age at the time of data collection. Both the quantitative analysis of logistic regression and the qualitative thematic analysis revealed that the child's age, the husband's income, the utilization of child care by relatives, the mother's job involvement, family-to-work role conflict, and other costs and rewards of participation in the work force were the important contexts where employed mothers considered leaving the labor force. The quantitative analysis uniquely found that being employed at a workplace with flexible work hours were associated with lower odds of considering exit from the labor market. The qualitative analysis highlighted that the decision to leave the labor force or to stay in it is a complicated issue that almost all employed mothers potentially face at some point in their careers. These findings suggest that policy support is warranted to help employed mothers with young children remain in the workforce when they wish to.

Purpose: Although linear-shaped gastroduodenostomy (LSGD) was reported to be a feasible and reliable method of Billroth I anastomosis in patients undergoing totally laparoscopic distal gastrectomy (TLDG), the feasibility of LSGD for patients undergoing totally robotic distal gastrectomy (TRDG) has not been determined. This study compared the feasibility of LSGD in patients undergoing TRDG and TLDG. Materials and Methods: All c: onsecutive patients who underwent LSGD after distal gastrectomy for gastric cancer between January 2009 and December 2017 were analyzed retrospectively. Propensity score matching (PSM) analysis was performed to reduce the selection bias between TRDG and TLDG. Short-term outcomes, functional outcomes, learning curve, and risk factors for postoperative complications were analyzed. Results: This analysis included 414 patients, of whom 275 underwent laparoscopy and 139 underwent robotic surgery. PSM analysis showed that operation time was significantly longer (163.5 vs. 132.1 minutes, P<0.001) and postoperative hospital stay significantly shorter (6.2 vs. 7.5 days, P<0.003) in patients who underwent TRDG than in patients who underwent TLDG. Operation time was the independent risk factor for LSGD after intracorporeal gastroduodenostomy. Cumulative sum analysis showed no definitive turning point in the TRDG learning curve. Long-term endoscopic findings revealed similar results in the two groups, but bile reflux at 5 years showed significantly better improvement in the TLDG group than in the TRDG group (P=0.016). Conclusions: LSGD is feasible in TRDG, with short-term and long-term outcomes comparable to that in TLDG. LSGD may be a good option for intracorporeal Billroth I anastomosis in patients undergoing TRDG.

Several studies about hospital malnutrition have been reported that about more than 40% of hospitalized patients are having nutritional risk factors and hospital malnutrition presents a high prevalence. People in a more severe nutritional status ended up with a longer length of hospital stay and higher hospital cost. Nutrition screening tools identify individuals who are malnourished or at risk of becoming malnourished and who may benefit from nutritional support. For the early detection and treatment of malnourished hospital patients , few valid screening instruments fur Koreans exist. Therefore, the aim of this study was to develop a simple, reliable and valid malnutrition screening tool that could be used at hospital admission to identify adult patients at risk of malnutrition using medical electrical record data. Two hundred and one patients of the university affiliated medical center were assessed on nutritional status and classified as well nourished, moderately or severely malnourished by a Patient-Generated subjective global assessment (PG-SGA) being chosen as the 'gold standard' for defining malnutrition. The combination of nutrition screening questions with the highest sensitivity and specificity at prediction PG-SGA was termed the nutrition screening index (NSI). Odd ratio, and binary logistic regression were used to predict the best nutritional status predictors. Based on regression coefficient score, albumin less than 3.5 g/dl, body mass index (BMI) less than $18.5kg/m^2$, total lymphocyte count less than 900 and age over 65 were determined as the best set of NSI. By using best nutritional predictors receiver operating characteristic curve with the area under the curve, sensitivity and 1-specificity were analyzed to determine the best optimal cut-off point to decide normal or abnormal in nutritional status. Therefore simple and beneficial NSI was developed for identifying patients with severe malnutrition. Using NSI, nutritional information of the severe malnutrition patient should be shared with physicians and they should be cared for by clinical dietitians to improve their nutritional status.

In order to meet the low voltage ride-through requirement in a grid code, a wind power plant (WPP) has to stay connected to a grid, supporting the voltage recovery for a grid fault. To do this, a plant-level controller as well as a wind generator (WG) controller is essential. The dynamic response of a WPP should be analyzed in order to design a plant-level controller. The dynamic response of a WPP for a grid fault is the collective response of all WGs, which depends on the wind speed approaching the WG. Thus, the dynamic response of a WPP should be analyzed by taking the wake effect into consideration, because different wind speeds at WGs will result in different responses of the WPP. This paper analyzes the response of a doubly fed induction generator (DFIG)-based offshore WPP with a grid fault taking into account the wake effect. To obtain the approaching wind speed of a WG in a WPP, we considered the cumulative impact of multiple shadowing and the effect of the wind direction. The voltage, reactive power, and active power at the point of common coupling of a 100 MW DFIG-based offshore WPP were analyzed during and after a grid fault under various wind and fault conditions using an EMTP-RV simulator. The results clearly demonstrate that not considering the wake effect leads to significantly different results, particularly for the reactive power and active power, which could potentially lead to incorrect conclusions and / or control schemes for a WPP.
