  • kDomestic studies on meteorologicaldata have been carried out, however they were mostly not constant but limited to fragment compilation. The studies on solar energy, among others, have been relatively active but the measurement of solar irradiance is also limited to some extent. This study, in an effort to identify the difference in data between solar radiance and cloud cover, was intended to compare and analyze the typical meteorological data developed by Korean Solar Energy Society with the solar irradiance calculated using the typical meteorological data and cloud cover data provided by current simulation program. Monthly average solar irradiance from the meteorological data (ISO TRY) of Korea's typical meteorological data which was actuallymeasured appeared to be far below the monthly solar irradiance from the American Department of Energy. The solar irradiance calculated based on cloud cover indicates very limited difference between the two data, so the solar irradiance measured by Korean typical metrologicaldata (ISO TRY) indicated the similar value, which demonstrates the solar irradiance data from Korean Meteorological Administration is more accurate than those US National Weather Center.

  • In our country, patients with diabetes mellitus are searching for complementary treatments to recover from illness, while they received treatments from the doctor. However, have been evaluated or investigated systematically. This study was carried out to explore application of complementary treatments for patients with DM. For this survey, questionnaires were developed by researchers and the data was collected from July to October of 1999. Among the 223 subjects, there is one general hospital, one oriental hospital, 15 area C.H.P, ahd 2 area health centers. The results were as follows: 1. The total number of cases was 223 and the average age was 62.85 years old and average duration of DM was 8.1 years. The number of patients who had experience with alternative therapies was 145 (65%). The number of those who have not undergone treatments was 78 (35%). 2. The 43.5% of experienced CAM were advised family and relatives. Only 30.3% approved the effect of CAM and 52.5% said that If another a new CAM is introduced, they will try it. 4. Ninety three kinds of complementary treatments were used. Among the used items, 63.7% was various types of plants, 21.6% was animal material and 14.7% was the mixed group. As a single item, Bombyx Mori (Silkworm) was the most frequently used (10.5%) followed by the bean, mushroom, Morus bombycis (mulberry), Ginseng, Commelina Communis (Dalgaebi), Chinese medicine, root of Rosa rugosa (Haedangwha). 5. Among the used items, Trichosanthes kirilowii Max. Eucommia ulmoides Oliver, Commelina Communis, Aralia elata, pine needle, mulberry fruit, root of Rosa rugosa. Ginseng, Lycii Fructus, Dioscorea radix, Polygonatum odoratum, Cassia tora L, Bombyx Mori, loach, Crucian carp were based upon the pharmacological function of effect for control of diabetes mellitus symptom. 6. In the analysis of the relationships between the general characters of the patients with new complementary alternative medicine try and hospital treatment; 1) The shorter group suffered from DM (p=.038), poor Self-MBG (p=.037) and wanted to try new complementary alternative medicine. 2) The group of DM education experience were carried out hospital treatment well (p=.045). In conclusion, further study will be required for the patients experience using alternative therapies as the D-M in terms of holistic view of patients.

  • Purpose - This paper aims to analyze the determinants of licensing behaviors of manufacturing firms empirically in non-advanced exporting countries. Research design and methodology - We try to approach licensing behavior from the perspective of innovation strategy and open innovation, and deal with two activities composing licensing, i.e. licensing-in and licensing-out using the result of Korean Innovation Survey Results - Firstly, Organizational characteristic factors, particularly the size and size related factors influence the firm behavior of licensing-out, but not in case of licensing-in. Secondly, innovation strategy influences the firm behavior of licensing-in, but not in case of licensing-out. Lastly, the determinants of licensing-in and that of licensing-out are different. Conclusions - In general, firms doing licensing-out have many complementary assets and orientation for global markets. Meanwhile, firms doing licensing-in are innovative firms utilizing patent as an appropriation mechanism. Licensing-out have relevance with product market-related factors and licensing-in have more relevance with technology market-related factors

  • Deep Learning is one of the machine learning methods to find features from a huge data using non-linear transformation. It is now commonly used for supervised learning in many fields. In particular, Convolutional Neural Network (CNN) is the best technique for the image classification since 2012. For users who consider deep learning models for real-world applications, Keras is a popular API for neural networks written in Python and also can be used in R. We try examine the parameter estimation procedures of Deep Neural Network and structures of CNN models from basics to advanced techniques. We also try to figure out some crucial steps in CNN that can improve image classification performance in the CIFAR10 dataset using Keras. We found that several stacks of convolutional layers and batch normalization could improve prediction performance. We also compared image classification performances with other machine learning methods, including K-Nearest Neighbors (K-NN), Random Forest, and XGBoost, in both MNIST and CIFAR10 dataset.

  • Agent technology has been widely applied in today's electronic business, such as mobile agents, multi-agent information systems, etc. In particular, multi-agent systems have been applied as powerful simulation tools to study complex business networks composed of various self-interested trading firms and/or human beings. In this paper, we build an integrated model that consists of a multi-agent B2C market model and a B2B trade network model, and incorporate more reality than much of prior work. Then with this model, we carry out experimental studies on two different strategies that are common in electronic business - 'loyal' strategy (retailers try to build stable cooperation with suppiers to ensure material supply) and 'cost-saving' strategy (retailers try to reduce cost by choosing suppliers with lower wholesale price).

  • The 3-dimensional finite element program is developed to analyze the non-isothermal forming processes of aluminum-alloy sheet metals. Bishop's method is introduced to solve the heat balance and force equilibrium equations. Also, Barlat's non-quadratic anisotropic yield function depicts the planar anisotropy of the aluminum-alloy sheet. To find an appropriate constitutive equation, four different forms are reviewed. For the verification of the reliability of the developed program, the computational try-outs of the non-isothermal cylindrical cupping processes of AL5052-H32 and Al1050-H16 are carried out. As results, the constitutive equation relating to strain and strain-rate, in which the constants are represented by the 5th-degree polynomials of temperature, is in good agreement with measurement. The computational try-outs can predict optimal forming conditions in non-isothermal forming processes.

  • There are several way to classify the furniture. The furniture can be classified into use, style, and function, but if the furniture is classified into the way of production, it can be the industrial furniture and the studio furniture. Especially, technology and function of the furniture are important elements in industrial furniture. However, it could be considered artists' character and concept as more important elements in the studio furniture. The studio furniture had come out one of the historical movement in American furniture field after the World War II. This case to apply found objects began to increase after the 1970s. Using objects In furniture design field had built up sprightly after end of 1950s. This expression could be the statement of new expression that essential properties of matter in objects is removed. I try to suggest original and interesting furniture design to apply found objects in this thesis. Especially, I use the Korean traditional objects for the furniture and try to make their essential function to be changed. Also, I focus on furniture design to have formative element in their shapes.
