City gas is becoming an essential resource in households due to its convenience and low price in comparison to other energy sources. However, in order to prepare for the gas market to be saturated, many city gas companies must pursue customer satisfaction management and develop happy call systems for a promising solution. In the development of the happy call systems, the difficult problem is that we cannot contact all customers because of limited resources and calling efficiency in the call center, We should find best customers according to their value. This paper suggests a methodology for the selection of happy call customers when city 9as companies consider two strategies. First, they should launch a new business area. Second, they must attempt to prevent current customers from moving from city gas to other fuels. We will discover important attributes and derive rules of weighting for the attributes through an exploration study that affect customer satisfaction and preference. Through a simulation model, we will show how many customers will be selected by our methodology.

Recently Software Industry has tended to enhance the productivity and quality with using the software architecture in software development and administration. The research of software component technique and software development methodology are just doing and making many applications. The software architecture is considered as the essential element for analyzing and maintaining the entire structure with organizing the software into components and describing the relations with connectors. The software modeling methodology that we propose is generating Happy Work Language describing the software structure with the modeling tool as Happy Work. We can use System Context Diagram, Component Diagram, Component Sequence Diagram, and they are composed of four Elements as Users, Systems, Components, Connectors.

The purpose of this study was to examine the relationship between career decision-making self-efficacy, character strength, and gratitude as a factor influencing the happy life of adults. Subjects were 89 adults in university and graduate school. SPSS 23.0 and PROCESS Macro were used for data analysis. Significant correlations were found between career decision-making self-efficacy, character strength, gratitude, and happy life. The direct effect of career decision-making self-efficacy, an independent variable, on happy life, a dependent variable, was not significant. Character strength and gratitude, which are mediators, were significant. Therefore, the indirect effect and the total effects showed significant results. Career decision-making self-efficacy does not directly predict a happy life, but if it mediates character strengths and gratitude, it means that a happy life can be predicted.

A new standard rose cultivar 'Happy Day' was bred from the cross between pink standard cultivar 'Vivaldi' and pink standard cultivar 'Medeo' at the National Institute of Horticulture & Herbal Science. The first cross was in 2003 and 'Happy Day' was finally selected in 2008 after investigating characteristics for three years from 2006 to 2008. 'Happy Day', a pink standard cultivar grows vigorously and has powder mildew resistance. The major characteristics of this cultivar are $160stems\;m^{-2}$ per year in yield, 79.2 cm in length of cut flower, 9.9 cm in flower diameter, 28.8 in mean petal number, and 11.8 days in vase life. This cultivar can be propagated by both cutting and grafting. The consumers' preference of this cultivar is relatively higher than that of control cultivar, 'Nobleless'.

This study is aimed to investigate the dimension feature of the plane about the economic type farming village Korean-style house progressed in the Chonnam province and Longitudinal feature and tries to reveal this feature through the comparing analysis with the traditional house positioned in the Chonnam province. This result is as follows. First, the main feature in plane is the setting up the column interval in front when comparing the house of Happy Village and traditional house. In case house of the Happy Village, after firstly fixed the limited scales, sizes are determined, this is due to control the set up in the post interval in this in range. Second, in the case of the traditional houses, 0.68 ratio of the building height about the side length and 0.19 ratio of the eaves extrusion about the side length are consistent ratio about dimensions. However, there is no consistent ratio or fixed law, the various dimensions show up in case of the house of Happy Village. It will be inevitable that space of the post increases for the convenience of life of the modern people. However, it has to sublate and to disregard as the identity of the morphological shown up in the Korean-style house the more various construction standards will need to be presented.

근래의 소프트웨어 관련업계에서는 소프트웨어 개발 및 관리에 있어 소프트웨어구조를 중심으로 생산성 및 품질의 극대화를 추구하고 있다. 또한 소프트웨어 컴포넌트 관련 기술 및 컴포넌트 기반 소프트웨어 개발 방법론에 대한 연구도 활발히 진행중이며, 많은 응용기술들이 나오고 있다. 소프트웨어 구조는 소프트웨어를 컴포넌트로 구성하고 그 사이의 상호작용을 커넥터를 이용해 기술함으로서 전체적인 구조를 분석하고 유지하는데 필수적인 요소로 고려된다. 본 연구에서는 우리가 개발한 HappyWork라는 모델링 도구를 사용하여 소프트웨어 구조를 설계하는 기법을 설명한다. HappyWork를 이용한 소프트웨어 구조 설계 과정에는 System Context Diagram, Component Diagram, Component Sequence Diagram과 같이 세 가지 다이어그램이 사용되며, 이 Diagram들을 User, System, Component, Connector와 같은 네 가지 element들로 구성된다.

This study examines the interaction effects between branded contents' ending types(happy ending, non-happy ending) and the level of product involvement(high involvement, low involvement) on consumer's negative responses. Results suggest that the level of product involvement had no significant effect on consumer responses since product on video clips was not closely linked to the contents' message. Selective empathy is identified as the happy ending type of branded contents had a greater effect on consumer's negative responses than the non-happy ending type of. It is an apparent new phenomenon shown among the young after 2000s. Moreover, the interaction between contents' ending types and the level of product involvement had a significant effect on consumer's negative responses. Two interaction terms (i.e. happy ending and low product involvement; non-happy ending and high product involvement) are the viable message strategies to weaken the consumer responses in terms of 'dislike'.

This study attempted to reveal the essential meaning of happy life for non-disabled children with disabled parents through a phenomenological research method for non-disabled children with disabled parents using welfare centers. As a result, 76 meaningful statements related to a happy life, eight categories of 20 topics have been drawn up, and the essential meaning of a happy life for a child is 'a happy life for parents', 'a life where parents are recognized' and 'a life where parents are no different from other families,' and 'a life where a child is living happily' as an 'economically stable life' and 'a life with disabilities' As such, I believe that since this period is important for children, there is a pressing need for ways to intervene and improve awareness of the disabled and the role of life.

A dark pink semi-double freesia (Freesia hybrida Hort.) 'Happy Birthday' was bred from a cross between 'Pink Jewel', F1 progeny of 'Michelle' and 'Rossini' as a female and 'White Lace' as a male parent. Test for the growth vigor and flowering characteristic were conducted from 2002 to 2007. A new variety 'Happy Birthday' has semi-double flower type with dark pink color (RHS color chart #RP66C). It has multiple flowers, distinctive flower shape, upright leaves and also stalks. The average yield of this variety 'Happy Birthday' counted over 6.7 stems per plant per season in the standard greenhouse cultivation method. It has also good production of cormlets, vigorous growth. A new variety 'Happy Birthday' is suitable for the greenhouse conditions during winter season in Korea.
