  • Design-build is expanding gradually in large construction projects over 10billion won, and continue to work in health care facilities is increasing in this way. This constructional method in health care facilities, despite the many advantages, many problems caused by design changes are being raised. Raises the question of design changes on the side of construction contract, such as approval systems have been studied in the field of construction. The purpose of this study design in aspects of architectural planning on changing the grasp of the issues outlined in the ITB and bid evaluation criteria through consideration of the basic plan for improvement guidelines and evaluation criteria is presented. In conclusion, Design build, according to the presence of existing users are more likely to lead to design changes. Thus, hospital architecture, depending on how it is considered that constructional methods. And evaluation items of ITB(Invitation To Bidder) for a large part of the change in the variables evaluated in the hospital building is not suitable for the design build. Instead, the overall shape of the building and department, unit type and size, vertical and horizontal parts of the circulation system in the shape of the building that does not change in structure and etc should be considered for evaluation.

  • In spite of the increasing popularity of the Ricardian model for the study of the impact of climate change on agriculture, there has been few attempts to examine the role of interregional spillovers in this framework and all of them rely on geographical proximity-based weighting schemes. We remedy to this gap by focusing on the spatial externalities of surface water flow used for irrigation purposes and demonstrate that farmland value, the usual dependent variable used in the Ricardian framework, is a function of the climate variables experienced locally and in the upstream locations. This novel approach is tested empirically on a spatial panel model estimated across the counties of the Southwest USA over 1997-2012. This region is one of the driest in the country, hence its agriculture relies heavily on irrigated surface water. The results highlight how the weather conditions in upstream counties significantly affect downstream agriculture, thus the actual impact of climate change on agriculture and subsequent adaptation policies cannot overlook the streamflow network anymore.

  • The purpose of this study is to analyse the effects of knit samples' mechanical properties on changes of skirt length of knit flared skirt, and to compare it to the knitting method of a seamless knitted flare skirt. So, I compared the appearance and 3-dimensional shape of a seamless knitted flare skirt with those of a fully cut knit flared skirt. For this study, 18 kinds of cut and sew or seamless knitted test garment were made. The data analysis methods used in this study were descriptive statistics, one-way ANOVA, correlation analysis, and regression analysis. The results are as follows: The result of the evaluation of knit samples' mechanical properties by the KES-FB system showed that elongation decreased as gauge increased and course direction was greatest among grain directions. The length change after wearing the knitted flare skirts appeared wholly equal to the seamless knitted, compared with the cut and sew. The change was biggest at $180^{\circ}$, 7G of the cut and sew. In grain direction, bias cut showed more than 1.2cm of length change. As the weight and thickness increased, the length changes become larger. The regression analysis indicated that the greatest contributive variables on the length changes were elongation, weight, and thickness.

  • Purpose: The purpose of this study was to identify the impact that health motivation, stage of change and cardiac risk factors have on health behaviors in Korean patients with coronary artery disease(CAD) admitted to hospital. Method: The participants in this study were 127 patients with CAD hospitalized between May 2008 and July 2009. A structured questionnaire with personal interviews and chart reviews were used to collect data. Data were analyzed using the SPSS. Results: Of the relatively significant factors, including a stage of change, self efficacy, modifiable risk factor score, and perceived barriers, stage of change was found to be the most significant predictor of health behavior in patients with CAD. These variables accounted for 48.2% of the variance in health behavior. Conclusion: The results of the study indicate the necessity of developing a cardiac rehabilitation program for use in their daily lives after discharge from the hospital. Stage of change should be assessed for all patients with CAD being discharged from acute care hospitals.

  • Soil moisture content is generally accepted as an important factor to understand the process of crop growth and is the basis of earth system models for analysis and prediction of the crop condition. To continuously monitor soil moisture changes at kilometer scale, it is demanded to create high resolution data from the current, several tens of kilometers. In this paper we described a downscaling method for Advanced Microwave Scanning Radiometer 2 (AMSR2) Soil Moisture Content (SMC) from 10 km to 30 m resolution using a soil texture and field measurements that have a high correlation with the SMC. As a result, the soil moisture variations of both data (before and after downscaling) were identical, and the Root Mean Square Error (RMSE) of SMC exhibited the low values. Also, time series analyses showed that three kinds of SMC data (field measurement, original AMSR2, and downscaled AMSR2) had very similar temporal variations. Our method can be applied to downscaling of other soil variables and can contribute to monitoring small-scale changes of soil moisture by providing high resolution data.

  • BACKGROUND/OBJECTIVES: Educational interventions targeted food selection perception, knowledge, attitude, and behavior. Education regarding irradiated food was intended to change food selection behavior specific to it. SUBJECTS AND METHODS: There were 43 elementary students (35.0%), 45 middle school students (36.6%), and 35 high school students (28.5%). The first step was research design. Educational targets were selected and informed consent was obtained in step two. An initial survey was conducted as step three. Step four was a 45 minute-long theoretical educational intervention. Step five concluded with a survey and experiment on food selection behavior. RESULTS: As a result of conducting a 45 minute-long education on the principles, actual state of usage, and pros and cons of irradiated food for elementary, middle, and high-school students in Korea, perception, knowledge, attitude, and behavior regarding the irradiated food was significantly higher after the education than before the education (P < 0.000). CONCLUSIONS: The behavior of irradiated food selection shows high correlation with all variables of perception, knowledge, and attitude, and it is necessary to provide information of each level of change in perception, knowledge, and attitude in order to derive proper behavior change, which is the ultimate goal of the education.

  • 본 논문에서는 약품비 지출에 대한 예측을 수행하기 위하여 시계열 모형을 도입한다. 2012년 약가 일괄인하를 반영하기 위하여 구간별 모형을 토대로, 자기회귀오차모형과 전이함수모형을 고려하였다. 자기회귀오차모형에서는 예측의 편리성을 위하여 결정적 추세만을 고려하였으며, 전이함수모형에서는 주요한 외생변수와의 교차상관성을 이용하여 약품비 지출의 인과 메커니즘을 설명하였다. 각 모형에서 약가 일괄인하 이후 수준 변화가 유의하게 나타났으며, 전이함수모형에서는 의약품 사용자 수 및 노인환자 비중 시계열 변수가 유의하게 나타났다. 자기회귀오차모형은 약가 일괄인하로 의한 약품비 수준이동에 좌우되어 비교적 낮은 예측값이 도출되었으며, 전이함수모형은 약품비 지출에 영향을 미치는 외부 설명변수의 증가 추세가 적절히 반영되어 더 높은 예측값을 보였다. 설명변수를 포함하지 않을 경우, 약품비 수준이동만을 고려한 ARIMA 모형은 약품비 지출 추세를 가장 높이 예측하였다.

  • Japan's frozen shrimp future market is the only fisheries future commodity market in the world. This empirical study examines the lead and lag relationship between Japan frozen shrimp spot and future markets using the daily prices from August 1, 2002 to December 31, 2005. Frozen shrimp future contract is listed on Japan Kansai Commodities Exchange. Japan imports approximately 250,000 tons of frozen shrimp annually, of which just under 70,000 tons, nearly 30%, are black tiger shrimp. Approximately 90% of black tiger shrimp are caught in Indonesia, India, Thailand and Vietnam, and the two largest consumers of these shrimp are Japan and the U.S.A. Kansai Commodities Exchange adopts the India black tiger shrimp as standard future commodity. We use unit root test, Johansen cointegration test, Granger causality test, Vector autoregressive analysis and Impulse response analysis. However, considering the long - term relationships between the level variables of frozen shrimp spot and futures, we introduced Vector Error Correction Model. We find that the price change of frozen shrimp futures with next 1, 2, 3, 4, 5 month maturity have a strong predictive power to the change of frozen shrimp spot and the change of frozen shrimp spot also have a predictive power to the change of frozen shrimp with next 1, 2, 3 month maturity. But, the explanatory power of the frozen shrimp futures is relatively greater than that of frozen shrimp spot.

  • Purpose: The purpose of this study was to review behavior change theories in terms of important variables, concept definitions, and applicability to diabetes self-management behavior. Methods: Six behavior change theories (the Transtheoretical Model, the Health Belief Model, the Theory of Reasoned Action, the Theory of Planned Behavior, Social cognitive theory, and Information-Motivation-Behavioral skills Model) were reviewed which were applied in diabetes self-management interventions. Results: The five key concepts from the five non-stage behavior change theories were delineated. Based on the key concepts, a theoretical framework was formulated as the explanatory model of diabetes self-management behaviors. The four major concepts in Information-Motivation- Behavioral skills Model were included. The cognitive arm of the proposed theoretical framework included constructs related to diabetes knowledge, motivation (beliefs, attitude, social norm), self-efficacy, and intention. Conclusion: The theoretical framework described here includes the key factors of successful diabetes self- management intervention. However, the concept of motivation needs further exploration and clarification for operationalization.
