Due to the diversification and complication of construction projects, controlling risks from the early design-planning phase gives huge impact on success of the construction project. As a part of managing uncertainties it is also important to estimate the project cost several times. Especially, estimating project cost in the early stage gives effects on making a budget for projects. This study estimated the apartment project cost using case-based reasoning(CBR), which is the process of solving new problems based on the past problems. For this, we deduced the apartment cost influence factors which can be gathered in the early stage of project. Based on the factors we established the database for apartment project and calculated the attribute value, attribute similarity and case similarity. Although we retrieve the most similar case from the database, it is very hard to utilize it directly due to the uniqueness of each project. So, Genetic Algorithm(GA) was applied in revising the cost of the retrieved-case. Therefore, the accuracy of the prediction was improved by GA optimization.

Influence of varying level of sodium bicarbonate (SB) supplementation on milk yield and its composition was examined in a randomized complete block design in early lactating Nili Ravi buffaloes during summer. Four iso-nitrogenous and iso-caloric diets were formulated. The diet 0B contained 0 while LB, MB and HB diets contained 0.50, 1.0 and 1.50% SB levels, respectively. The diets were randomly allotted to twenty buffaloes, five in each group. A linear increase in nutrient and water intake was recorded with increasing SB level. Buffaloes fed MB and HB diets showed higher nitrogen balance than those fed 0B and LB diets. A significant increase in blood pH and serum bicarbonate was noticed with increasing SB level. Urine pH increased significantly with increased SB level. A linear increase in milk yield was also noticed with increasing SB level. Milk fat% increased significantly in buffaloes fed MB and HB diets compared with those fed 0B and LB diets. Buffaloes fed HB diet had higher conception rate and less services per conception than those fed 0B diet. This study indicated that a high SB diet not only increased dry matter and water intake, milk yield, milk fat% but also increased conception rate in early lactating buffaloes during summer.

Purpose: This study was to compare the effects of early ambulation to usual care of late ambulation in patients with transarterial chemoembolization on back pain, discomfort, and puncture site complications. Methods: A nonequivalent control pretest-posttest design was used. Total 40 patients were recruited from a gastrointestinal unit of an urban general hospital in Seoul, South Korea. The experimental group began to ambulate after 4 hours of bed rest with a compression bandage after receiving transarterial chemoembolization. The control group stayed in bed with a compression bandage overnight. Results: Back pain was not significantly different between the two group. The experimental group reported significantly lower discomfort than the control group. There was no incidence of bleeding complications on puncture site between two groups. Conclusion: The results of this study showed that early ambulation with four hours of bed rest after femoral sheet removal did not cause bleeding complications compared to the usual care and even decreased patients' level of discomfort due to bed rest. Repetitive research on the effect of short bed rest is warranted for its clinical utilization.

Purpose - This study aims to illustrate the relationship between demographic factors and perceived risk types, supposing that Korean customers tend to postpone buying or hesitate to purchase the new version of hand sets, because of an early buying risk. Research design, data, and methodology - In addition to existing perceived risk types, the authors introduced an early buying risk. In order to measure each variable, also, the study has employed a five-point Liker-scale. To increase research reliability and validity, the research adopted an exploratory factor analysis, a confirmatory factor analysis, and one-way ANOVA. Results - First, there were statistically significant differences between financial risk and the group. Second, there weren't any statistically significant differences between the group means among the four perceived risk types (Performance Risk, Social Risk, Psychological Risk, and Physical Risk) and 4 factors (Gender, Age, Job, and Education). Lastly, job is apparently differentiated from others (Gender, Age, and Education). Conclusions - The authors found that customers regarded an early buying risk as one of the important perceived risk types, when purchasing a hand set.

This study was carried out to investigate the influence of the seeding dates on the yield and feed value in cultivating Italian rye grass on paddy soil. The field experiment was designed in a randomized block design of 3 repetitions with seeding dates of Oct. 19 (T1), Oct. 26 (T2), Nov. 2 (T3), Nov. 9 (T4), and Nov. 16 (T5) treatments. Plant length, fresh yield, dry matter yield and TDN yield were increased with early seeding dates (p<0.05). Crude protein, Crude fat and crude ash were increased with early seeding dates (p<0.05). On the other hand, NDF, ADF and Crude fiber were decreased with early seeding dates (p<0.05). Total mineral contents were higher in the order of T4 > T3 > T5 > T1 > T2 (p<0.05). The total composition amino acid content was decreased significantly (p<0.05) as the seeding dates delayed. Total free sugar content was highest in T1, whereas the lowest in T5 treatment (p<0.05). Nutrition yields (crude protein, crude fat, amino acid and free sugar) were increased significantly with early seeding dates (p<0.05). The above result indicated that it is favorable to seed soon after rice harvest to increase dry matter yield and nutrition yield of Italian ryegrass in the midlands.

Purpose: The purpose of this study was to compare musculoskeletal pain, menopausal symptoms and depression by women's menopausal stage. Method: With a survey design, a convenience sample of 203 women between age of 40 to 64 was recruited through a community. Data were collected via a structured study questionnaire from May to July, 2008. Measures included with symptom severity list for menopausal symptoms, Aches and Pains scale, and Beck's Depression Inventory. Results: Thirty-seven percent of women belong to early peri-menopausal stage, 31% to late peri-menopausal stage, and 32% to postmenopausal stage. By group comparison, late peri-menopausal and post menopausal women reported higher scores of depression than early peri-menopausal women. Postmenopausal women had greater scores in two pain subscales (bodily pain and pain that interferes with normal work) and two menopausal symptoms subscales (sleep pattern and sexual behaviors) than early peri-menopausal women. There were moderate levels of positive relationships among study variables at each menopausal stage. Conclusion: Postmenopausal women seem to have greater musculoskeletal pain and menopausal symptoms, and have depression more than did early peri-menopausal women. Tailored nursing strategies are required to reduce these kinds of common symptoms for women with menopausal transition to improve their physical and psychological wellbeing.

Through reinvestigations of early years of King Young-Joe provincial castles, Jeonju Eupsung, this study seeks to broaden the understanding of castle construction of the later period of Chosun Dynasty. Jeonju Eupsung was established by reform-minded king and his loyalist Cho, Hyun Myung. Their new conceptual framework for reconstruction of Jeonju Eupsung was affected by Yoo, Hyung Won, a realist scholar of 17th century. It is obvious that adopted new administrative systems of financing, building and maintaining of Jeonju Eupsung were based on the his theories of castle. This study demonstrates that Jeonju Eupsung built by Cho, Hyun Myung, during the early years of King Young-Joe were based on those new concepts and systems of the new age. The study shows that the designer of this castle had in mind efficient construction design and execution and effective defense of provincial towns located on flat ground. And, the study explains how those original designer sought higher productivity through greater localization of securing resources and more detailed and improved organization of construction responsibilities. In short, this study seeks to prove that the provincial castles of the early 18th century reflected the new thinking on practicality that was spreading throughout the society of Chosun Dynasty at the time.

Purpose: The purpose of the study is to identify differences in BMI between early and late elderly people, and factors having influence of them. Methods: This study is an analysis of secondary data that used the raw materials from the KNHANES from 2008 to 2010. The subjects involved in the final analysis were 4,772 elders aged 65 or higher. Descriptive statistics, $x^2$-test and F-test, and CSGLM from the complex sample design were used for the data analysis with SPSS/WIN 19.0. Results: Significant differences were observed in the socio-demographic characteristics, health behaviors and diet habits between early and late elderly people. Adjusted for gender, location of residence, and living alone, the factors that affected BMI of the early elderly people included current smoking status, number of disease, difficulty in chewing, and number of meals per day while those that affected BMI of the late elderly people were current smoking status, number of disease, self-rated health, and difficulty in chewing. Conclusion: The study concludes that we should consider age-specific traits for monitoring the weight status of the elderly and providing appropriate weight management programs for the elderly.

This study traces the flow of modern museum architecture from the 18th to 19th century when the rationalist architectural spirit influenced the museum architecture to the 1930s, before the museums of the modern architectural masters appeared. With early modern museums until the 1930s as a target, which had long been enshrined in classicality, finally contributed to narrowing the gap with the times, but did not receive the right evaluation, this study examines their different architectural styles from previous museums and reveals that they have a significance to announce the departure of modern museums beyond classical ones. The three museums, built in the 1930s, will be identified as respectable early modern museums that will fill the remaining blank space of the history of museum architecture. In this study, modern museums are asymmetric, non-centre oriented, and non decorative. They have multi-directional circulation, and a neutral, open and flexible exhibition space. They also try to align themselves with the modern architectural tendency of the day.
