This study focuses on Yusam, a military raincoat that was worn during the Joseon Dynasty. The purpose of this study is to review the types and management system of Yusam. Documentary records, paintings and relics were used as research materials. Yusam was recorded as either Yusam(油衫) or Yu-ui(油衣) in writing. It usually looked like a skirt and was worn like a cape, but there were differences in length. Some of them took the form of a short coat with half-sleeves and side slits. Research analysis results of Silrok, Ilseongrok and the archives of the military camp in the later Joseon are as follows: First, Mokyusam and Jiyusam coexisted as military raincoats. Mokyusam was made with cotton and perilla oil, while Jiyusam was made with traditional Korean paper, a cotton edging and perilla oil. Second, the differences between general Yusam and military Yusam include the material of the clothing, the materials for waterproofing, the color, and the manufacturer. Third, each military camp supplied soldiers with hundreds to thousands of Yusam. Military officers and King's guards wore Mokyusam because Mokyusam was higher than Jiyusam. Fourth, soldiers Yusam together with Yujeongeon, Chorip, Galmo, or Hwihang as a hat. Fifth, the higher the rank, the higher the price of Yusam and the longer the term of usage. On the other hand, as the rank got higher, the cost of the supplementary oil rose, while the duration of usage got shorter.

Construction industry ranks as the largest industry and imparts a significant part in developing and achieving the aims of society. Due to the involvement of larger number of stakeholders, construction industry is complex in nature. The current study is designed to identify and evaluate the factors affecting the success of construction projects in Khyber Pakhtunkhwa (KP), Pakistan. To carry out the study, a questionnaire was developed in term of interview pilot study. The data from the questionnaire survey was analyzed through SPSS software in five groups to accumulate authenticity of 44 factors. Later on the ranking was done by relative importance index (RII). According to the outcome of the research, "Project Group" stood highest among the five groups with factor of "project size" at the top rank while "Contractor Group" stood lowest with the factor of "client size" at bottom rank. From the study it is concluded that the Project Group is identified as a crucial blockade in success of construction projects. By giving pivotal attention to project group, the projects could be successfully attained from factors of project size, materials and equipment, funds and resources and project planning. To focus on the factors of project group, trust of the province people could be restored in construction of projects.

The storage stability from powdered anchovy and its preparation cooperated with three additives (water extract from green tea and boxthorn and BHT) was studied. The results are as follows: 1. When the additives were added to powdered anchovy, the storage stability was improved. The antioxidative activities of water extract from green tea and boxthorn were considerably higher than BHT. The antioxidative activities were decreased in the rank order boxthorn > green tea> BHT. 2. The more the concentration of natural additives was increased, the more the storage stability was improved. The rank order was$60^{\circ}>40^{\circ}>20^{\circ}$ Bx. 3. The A V and POV of powdered anchovy were increased in the rank order to 6 < 12 < 18 < 24 < 30 months by storage term. 4. This clearly suggested that water extract at $20^{\circ}>$ Bx level from boxthorn was possible utilization as a new natural antioxidant for storage stability of powdered anchovy.

The reasonable prediction of time-dependent deformation of prestressed concrete(PSC) box girder bridges is very important for accurate construction as well as good serviceability. The long-term behavior is mostly influenced by the probabilistic characteristic of creep and shrinkage. This paper presents a method of statistical analysis and sensitivity analysis of creep and shrinkage effects in PSC box been taken into account - model uncertainty, parameter variation and environmental condition. The statistical and sensitivity analyses are performed by using the numerical simulation of Latin Hypercube sampling. For each sample, the time-dependent structural analysis is performed to produce response data, which are then statistically analyzed. The probabilistic prediction of the confidence limits on long-term effects of creep and shrinkage is then expressed. Three measure are examined to quantify the sensitivity of the outputs of each of the input variables. These are rank correlation coefficient(RCC), partical rank correlation coefficient(PRCC) and standardiozed rank regression coefficient(SRRC) computed on the ranks of the observations. Three creep and shrinkage models - i. e., ACI model. CEB-FIP model and the model in Korea Highway Bridge Specification - are studied. The creep model uncertainy factor and the relative humidity appear to be the most dominant factors with regard to the model output uncertainty.

This paper deals with the comparative analysis the two surveys called term1, term2 by collecting 4-digit password data 1313 for 2006~2011 and 2519 for 2012~ 2017. Numbers lacking prudence were significantly reduced in the term2 survey and over time, the use of four digit PWs became increasingly prudent. There was a difference in the use of digit numbers between male and female. The top five types accounted over 60%, which imply that certain types of preferences are present. It was the outcome of this paper that we can indirectly deduce these facts. Studies such as reuse of four digit PWs in user's convenience will need to be supplemented in the near future.

Purpose: As our population ages and becomes an elderly society the number of elderly care hospitals is rapidly increasing. Because physical functions and spatial perception in the elderly decrease with age, these hospitals require more systematic and intelligent space designs. The design of these spaces are even more complex because they must accommodate medical programs to treat various different diseases and ailments and also because there are many first time patients and irregular short term patients that seek out outpatient treatment services. Also by analyzing the spatial configuration systems and systematic relationships between each of the functional spaces of the outpatient treatment service departments for hospitals specialized in care for the elderly by focusing on the hallway and corridor systems of these hospitals, the according characteristics and trends were examined. Methods: Based on preceding research, the types of hallway and corridor systems of these hospitals were categorized into five types, including gallery corridors, middle corridors, hall-type, mixed type and cyclic type corridors, and into six types according to function including by medical diagnosis, patient registration, examination, administration and convenience and shared common space to derive any interconnecting relationships between the corridor systems. Also by comprehensively examining the types and combined utilization of the corridor types and the integration and the intelligibility of the space syntax, any trends within the corridor system were derived. The elderly care hospitals examined in this research study were twelve hospitals that opened after the year 2000 in Korea with more that 150 sick beds with areas larger than $1000m^2$ and with all outpatient medical service related rooms located entirely on a single floor of the hospital. Results: The following results could be confirmed based on this research study. 1) The spaces where medical diagnosis and examination occurred were adjacent, and the movement lines for first time patients and re-visiting patients were taken into consideration by separating the treatment space. 2) This research study confirmed that the larger the size of the hospital was, there were more detailed categorizations of treatment services and that there was a tendency for treatment areas to be separated and independent from examination areas. 3) There was a tendency for integration and intelligibility to decrease the more complex and diverse the combination of hall types designed into the corridor systems of these hospitals was. cyclic type corridors dramatically decreased the intelligibility of the corridor systems of these hospitals. 4) The priority rank of these spaces were confirmed to be highest in the order of registration, diagnosis, examination, treatment, administration and shared common spaces. However it was confirmed for the local integration that the diagnosis scope had the highest priority rank. Implications: There were exceptional cases confirmed where the number of unit spaces did not have an absolute effect on integration and intelligibility. These results can be interpreted to mean that this can be overcome through efficient architectural planning.

Objective: The present study aimed to assess the relationship between incidental abnormalities on thoracic computed tomography (CT) and mortality in a general screening population using a long-term follow-up analysis. Materials and Methods: We retrospectively collected the medical records and CT images of 840 participants (mean age ± standard deviation [SD], 58.5 ± 6.7 years; 564 male) who underwent thoracic CT at a single health promotion center between 2007 and 2010. Two thoracic radiologists independently reviewed all CT images and evaluated any incidental abnormalities (interstitial lung abnormality [ILA], emphysema, coronary artery calcification [CAC], aortic valve [AV] calcification, and pulmonary nodules). Kaplan-Meier analysis with log-rank and z-tests was performed to assess the relationship between incidental CT abnormalities and all-cause mortality in the subsequent follow-up. Cox proportional hazards regression was performed to further identify risk factors of all-cause mortality among the incidental CT abnormalities and clinical factors. Results: Among the 840 participants, 55 (6%), 171 (20%), 288 (34%), 396 (47%), and 97 (11%) had findings of ILA, emphysema, CAC, pulmonary nodule, and AV calcification, respectively, on initial CT. The participants were followed up for a mean period ± SD of 10.9 ± 1.4 years. All incidental CT abnormalities were associated with all-cause mortality in univariable analysis (p < 0.05). However, multivariable analysis further revealed fibrotic ILA as an independent risk factor for all-cause mortality (hazard ratio, 2.52 [95% confidence interval, 1.02-6.22], p = 0.046). ILA were also identified as an independent risk factor for lung cancer or respiratory disease-related deaths. Conclusion: Incidental abnormalities on screening thoracic CT were associated with increased mortality during the long-term follow-up. Among incidental CT abnormalities, fibrotic ILA were independently associated with increased mortality. Appropriate management and surveillance may be required for patients with fibrotic ILA on thoracic CT obtained for general screening purposes.

Reliable long-term dam inflow prediction is necessary for efficient multi-purpose dam operation in changing climate. Since 2000s the teleconnection between global climate indices (e.g., ENSO) and local hydroclimate regimes have been widely recognized throughout the world. To date many hydrologists focus on predicting future hydrologic conditions using lag teleconnection between streamflow and climate indices. This study investigated the utility of teleconneciton for predicting dam inflow with 1-month lead time at Andong dam basin. To this end 40 global climate indices from NOAA were employed to identify potential predictors of dam inflow, areal averaged precipitation, temperature of Andong dam basin. This study compared three different approaches; 1) dam inflow prediction using SWAT model based on teleconneciton-based precipitation and temperature forecast (SWAT-Forecasted), 2) dam inflow prediction using teleconneciton between dam inflow and climate indices (CIR-Forecasted), and 3) dam inflow prediction based on the rank of current observation in the historical dam inflow (Rank-Observed). Our results demonstrated that CIR-Forecasted showed better predictability than the other approaches, except in December. This is because uncertainties attributed to temporal downscaling from monthly to daily for precipitation and temperature forecasts and hydrologic modeling using SWAT can be ignored from dam inflow forecast through CIR-Forecasted approach. This study indicates that 1-month lead dam inflow forecast based on teleconneciton could provide useful information on Andong dam operation.

Objectives: This study is aimed to determine any differences in the postoperative stability between absorbable and titanium plate systems for fixation in orthognathic surgery with simultaneous maxillomandibular procedures especially including maxillary posterior impaction and advancement. Study Design: Forty patients with dentofacial deformities were randomly assigned into titanium (4 males and 6 females) and absorbable (17 males and 13 females) fixation group. All patients had undergone surgical alterations of maxilla with posterior impaction and advancement. A comparison study of the change in the maxillary position after the simultaneous surgery was performed with 1-day, 6-months postoperative lateral cephalograms compared to preoperative lateral cephalogram by tracing. Wilcoxon rank sum test was used for statistical analysis. Result: The position of the maxilla was stable after surgery and was not changed significantly from 1 day to 6 month after the simultaneous maxillomandibular surgery both in the experimental (absorbable plates) and control (titanium plates). Conclusion: This study suggests that application of absorable plating system in the fixation of maxillary segment in the simultaneous maxillomandibular procedures, leads to a predictable short-term postoperative skeletal stability comparable to the titanium plating system. Long term follow-up and further studies will be needed.

The purpose of this study was to assess the degree of stress and patterns of coping for that Stressful events on family members because of the hospitalization of the patients. Stress and coping were measured with a tool on the basis of Volicer and Bell's questionnaire. In data collection, the modified 38 items of Volicer's stress scale and Bell's 18 item coping scale were administered. The subjects consisted of 259 family members of general ward-patients in Seoul National University Hospital during April in 1990. They were randomly selected on the basis of relationship of patients; patient's spouse, patient's daughters or sons. The stressors of the family members were ranked as follows; The first rank Stressful events was related to the patient's diseases and pain, the second ones was related ·to caring of their patients and family's psychosocial life. Families used long term coping method significantly more than short term ones. The results indicated that there was no difference in use of coping method between pre and post hospitalization. Finding out more about situation and optimism were the most common coping methods, and the least frequent coping method was the use of drugs. In conclusion, the identification of perceived stress and coping patterns of family members provides useful information for family nursing and aimes at better nursing care for the hospitalized in patients.
