가지 육종을 위한 기초 자료를 얻고자 9품종을 교잡하여 $F_l$ 세대의 11개 조합을 재료로 각 형질들의 측정치로서 우성의 정도와 잡종강세를 평가하였다. $F_l$세대의 잡종강세는 초장, 경경, 과중, 엽장, 엽폭, 주당과수 등이 초우성으로 유전되었다. 그리고 과장과 과경은 불완전 우성으로 유전되었다. Heterosis의 정도는 초장, 경경, 과중, 과장, 과경, 엽장, 엽폭, 주당과수 등 8개 형질 모두에서 정(+)의 강세를 보였다. Heterobeltiosis의 정도는 초장만이 정(+)의 강세를 보였고, 과경, 엽폭, 엽장, 과중, 주당과수, 과장, 경경은 부(-)의 잡종강세를 보였다 This experiment was performed to obtain the basic information on heterosis and heterobeltiosis of quantitative characters in the eggplant by crossing of varieties. The heterosis and heterobeltiosis were estimated in Fl generation. The results were as follows, based on the graphical analysis, the characters, plant height, stem diameter, fruit weight, leaf length, leaf width, and fruit number per plant(yield) were assumed to inherit dominance, and fruit length and fruit diameter were found to inherit incomplete dominance. The degree of positive heterosis of plant height, stem diameter, fruit weight, fruit length, fruit diameter, leaf length, leaf width, and fruit diameter, leaf width, leaf length, fruit weight, and stem diameter showed negative heterobeltiosis.

As a result of analysis, Wu-yi has the highest value in leaf length (9.45 cm), width (3.88 cm), and area (25.84 cm2) and it also has the highest weight value of dry (0.38 g)/fresh (0.71 g) leaf. Asanoka has the highest value in leaf stalk length as 0.61cm, Taiwan tea (Daecha No. 21) has the largest value in the number of serrate as 21.60 while Jeju No.1 has the largest value in the number of vein as 9.80. Jeju No. 2 has the lowest value in leaf length (6.65 cm), width (2.25 cm), area (10.6 cm2), and the number of serrate (15.07) as well as it has the lowest weight value of dry (0.07g)/fresh (0.28 g) leaf while Jeju No.1 has the lowest value in leaf stalk length (0.16 cm). Taiwan tea (Daecha No.21), Mayryoku, and Asanoka have the same value in the number of vein (7.07) as the lowest value. As a result of analysis for heritability, genetic variance and environmental variance of tea leaves, the values of genetic variance are higher than the values of environmental variance in all the traits. The value of genetic variance is the highest in leaf area as 23.4734 as well as the value of environmental variance is the highest in leaf area as 5.0496, However, the value of environmental variance tended to lower overall. The value of heritability is the highest in leaf stalk length as 99.95%, the weight value of dry leaf, leaf width in order. The value of heritability is high as more than 70% in all the traits and therefore it would be easy to select superior traits.

본 연구는 컷오프 수준에 따라 활성화 셀(cell) 수와 래더(ladder) 수 등의 통계량의 변화들 살펴보고, 컷오프 수준의 변화에 따른 가치 맵이 어떻게 변화하는지를 제시하며, 주어진 조건(100명의 응답자에게 최대 5개의 중요한 속성을 선택하도록 하여 가치사슬을 만든 후 이를 이용하여 가치 맵을 그렸을 경우)하에서 정보손실을 최소화하면서 설명력이 있는 최적의 컷오프 수준 결정과 이에 따른 가치 맵을 표현하고자 한다. The Means-end theory has successfully been applied in academics circles and is one of the qualitative methodologies, aiming at classifying into groups based on the specific values that they pursue. The more specific purposes of this study is to identify the relationship between the levels of abstraction and HVM(Hierarchical Value Map) and to identify the statistical changes in frequency activated cell and ladders among A-C-V. And lastly, to suggest the HVM according to the levels of abstraction. The subjects of this study includes the 100 hikers who joined the hiking at least once a year for 2007. The results of analysis show that as the level of abstraction goes up, the HVM itself is depicted more simple and the loss of information is also occurred. Consequently, the decision of levels of abstraction is should be made on the basis of objective validity.
