A new rose cultivar, 'Pure Heart' was selected from the progenies of a cross between 'Saphir' and 'Crystal Line' at the Gyeonggi-Do Agricultural Research and Extension Services in 1998. It was finally selected in 2002 after evaluation trials for three years (2000-2002). 'Pure Heart' was developed for a standard-type cut flower. 'Pure Heart' has some good agricultural and marketing traits. 'Pure Heart' has good qualified flower of which color is fair bright pink, 6.8cm in flower diameter and 4.5cm in flower height. 'Pure Heart' produce $122stems/m^2$ in a year, and has 45 petals per flower. The length of cut flower was long with 66.0cm. Vase life of the cultivar could be as long as 8 days. Futhermore marketing-quality was good in some aspects. The cultivar was applied for a variety protection in 2004 and was released to commercial growers in 2005.

A rose cultivar "Haedoji" developed at the Jeollanamdo Agricultural Research and Extention Services (JARES) is a standard type with deep Red flower. From 2000, two cultivars 'Vital' and 'Cardinal' were examined for horticultural characteristics and were included in cross-combination in 2003. Cultivar 'Vital', a vigorous standard type, first preference with red flower, was used as a mother plant and cultivar 'Cardinal', a red flower standard type with light color, was used as a pollen-donor plant. seventeen six breeding lines were selected in 2004 based on flower shape, flower color and abundance of petal numbers on the first selection. two breeding lines were selected in 2004 based on powderly mildew and vigor on the second selection. For three years, from 2005 till 2007, one breeding lines were selected and examined for their productivity, and then cultivar "Haedoji" was developed because of distinctive characters such as light red color flower, upright stem, long vase-life and Resistance to the Powderly Mildew. A standard type with intermediate sized flower, cultivar "Haedoji" shows in average 9.2 cm flower diameter, 62.0 cm flower stem length, and 9.5 days vase-life. The average productivity for three years was $167.3stems{\cdot}m^{-2}$ per year and increased 2% compare to cultivar 'Tiamo' with $163.9stems{\cdot}m^{-2}$ per year.

In the present study, the wind characteristics were analyzed according to the time averages to evaluate the performance of small wind turbines required for the development of energy independent village. Measuring data of wind speed were recorded between January 2016 and April 2016 every second. Experimental data is averaged out using 5, 10, 15, 20 and 30 minute time steps. Throughout the experimental data analysis, 5 minutes averaged data is used to analyze the performance of the wind turbine, because it produces a minimum turbulence intensity in wind speed. The measuring power of the wind turbine is less than the designed value due to the unsteady nature wind of sudden changes in magnitude of wind speed and wind angle. Detailed wind conditions are also analysed using two variable Weibull probability density functions.

With the development of Information Technology, customers require promptly higher quality products and services. Companies try to make newly digital marketing strategies, but there are no empirical researches on them. This article empirically presents a new perspective that companies can shape the customer decision journey ahead by coordinating customer experience. In this article, based on Elaborated Likelihood Model (ELM) theory, customer experience consists of the emotional or cognitive experience. We surveyed about 200 subjects (N = 217) in their 20s and 30s based on the International Music Industry Association's Music Listening 2019 report, then analyzed four different models (before personalization-cognitive experience, before personalization-emotional experience, after personalization- cognitive experience, after personalization-emotional experience) by JASP and R Studio. We conducted Structural Equation Model (SEM) and paired t-test. Personalization factors are about recommendation systems in Spotify. The results of survey represent that companies can shape the Customer Decision Journey (CDJ) ahead especially through enhance cognitive experience. It empirically proves Elaborated Likelihood Model (ELM). The conclusion can be drawn that 'pulling' customer experience can be a new marketing strategies in the digital era.

A new Hibiscus cultivar 'Daewangchun', having vigorous growth, uniform plant habit, upright, compact branches, and a long red eye was developed through interspecific crosses between H. syriacus 'Samchully' (♀) and H. sinosyriacus 'Seobong' (♂). The Hibiscus breeding program was initiated in 2005 and Hibiscus ${\times}$ 'Daewangchun' was preliminarily selected as '05-R-204' in 2 008 due to its vigorous growth and stable flower quality w ith rich pink flowers. The s elected line was further evaluated for different growth characteristics, leaf shape, leaf size, and flowering characteristics, as well as tested for distinctness, homogeneity, and stability during 2010-2012. The new cultivar 'Daewangchun' had violet pink flowers (RHS N80C) with a long red eye spot, medium size and fan petals. The size of flower was 12.0 cm and size of the red eye was 3.0 cm. Leaves were 8.7 cm long and 4.7 cm wide. After plant characteristic evaluation for 3 years (2010-2012), 05-R-204 was registered as cultivar 'Daewangchun' (4731, No. of plant variety protection rights) in 2013. This newly developed cultivar 'Daewangchun' has tall vigorous growth and unique flowers with a long red eye and can be used as specimen plants in landscaping.

Nondestructive radiography using cosmic ray muons has been used for decades to monitor nuclear reactor and spent nuclear fuel storage. Because nuclear fuel assemblies are highly dense and large, typical radiation probes such as x-rays cannot penetrate these target imaging objects. Although cosmic ray muons are highly penetrative for nuclear fuels as a result of their relatively high energy, the wide application of muon tomography is limited because of naturally low cosmic ray muon flux. This work presents a new image reconstruction algorithm to maximize the utility of cosmic ray muon in tomography applications. Muon momentum information is used to improve imaging resolution, as well as muon scattering angle. In this work, a new convolution was introduced known as M-value, which is a mathematical integration of two measured quantities: scattering angle and momentum. It captures the objects' quantity and density in a way that is easy to use with image reconstruction algorithms. The results demonstrate how to reconstruct images when muon momentum measurements are included in a typical muon scattering tomography algorithm. Using M-value improves muon tomography image resolution by replacing the scattering angle value without increasing computation costs. This new algorithm is projected to be a standard nondestructive radiography technique for spent nuclear fuel and nuclear material management.

In Rough set, attribute missing values have several problems such as reduct and core estimation. Further, they do not give some discernable pattern for decision tree construction. Now, there are several methods such as substitutions of typical attribute values, assignment of every possible value, event covering, C4.5 and special LEMS algorithm. However, they are mainly substitutions into frequently appearing values or common attribute ones. Thus, decision rules with high information loss are derived in case that important attribute values are missing in pattern matching. In particular, there is difficult to implement cross validation of the decision rules. In this paper we suggest new method for substituting the missing attribute values into high information gain by using entropy variation among given attributes, and thereby completing the information table. The suggested method is validated by conducting the same rough set analysis on the incomplete information system using the software ROSE.

A new cultivar of Rosa hybrida 'Loving Heart' was developed by crossing Gyeongkyo R-6 and 'Noblesse' at Gumi Floricultural Experiment Station in 2002. Characteristics trials were conducted three times from 2004 to 2007. This cultivar showed dark pink flower color (RHS, Red-purple group 66-B) and standard type with good flower shape. The flower diameter is 10.3cm and the number of petals per flower is 55. Vase life of 'Loving Heart' could be as long as 12.3days. The yield of 'Loving Heart' was $127stems/m^2/year$. 'Loving Heart' has good quality of cut flower and strong vigor in plant growth. This cultivar has straight stems and is easy to culture because of a few prickles on the top of stem. This cultivar is appropriate for both soil and solution(hydroponics) cultures.
