  • A new gerbera cultivar 'Paspin' was released by the National Institute of Horticultural & Herbal Science (NIHHS) in 2009. A cross was made between 'Lilabella' and 'Mephisto' with purple and semi-double in 2005. After investigation of the characteristics for five years (from 2005 to 2009), it was selected specially as a cut flower. The 'Paspin' cultivar has a pastel pink flower color (RHS R52B) with green disc center and semi-double flower. It has large-sized flowers which average flower diameter is about 12.8 cm. And inner ray floret and disc diameters are 7.87 cm and 2.57 cm, respectively. It has an adequate peduncle height of 48.6 cm, and a longer vase life of 10.8 days. It is vigorous in growth and also adaptable to the local cultural environments of Korea. It is expected that if the 'Paspin' cultivar will be planted, the royalty fees to be paid to other countries can be saved. And the local growers will also be benefitted since the cost of cultivars will be lower than the imported ones.

  • The subjects were individually presented with the Maxi-doll task to examine false belief and with the flower-star (Stroop-like day-night) test to examine inhibitory control skill. In the $1^{st}$ session, the subjects were tested with both the Maxi tesk and the flower-star test. Three days later, subjects were retested with the Maxi task, including an inhibitory cue. Data were analyzed by 3-way ANOVA, age(2) $\times$ inhibitory level(2) $\times$ task type(Maxi-task or Maxi-including cue). All the main effects were significant and the interaction effect between inhibitory level and task type was also significant. Thus, their understanding of the mind and inhibitory control skill both influence children's performance on a typical false belief task.

  • Experiments were conducted to evaluate the effect of low temperature-darkness treatment on floral initiation in four kinds of Korean strawberry cultivars. Mother plants were planted on March 29 and daughter plants were raised for the experiment. Temperature treatment was done for 7, 14, and 21 days keeping $13^{\circ}C$ in cooling storage from August 29, September 5 and September 14 to September 21. After the treatment, flower bud initiation was examined by a microscope, and the seedlings were transplanted on hydroponic system with Yamazaki's strawberry solution of EC $0.8dS{\cdot}m^{-1}$ to check the flowering. 'Ssanta' and 'Maehyang' showed early flower bud initiation in 7 days treatment than 'Seolhyang' by microscope check. 'Ssanta', 'Daewang', and 'Maehyang' showed early flower bud initiation in 14 days treatment than 'Seolhyang'. There were no differences among the treatments in 21 days treatment. Percentage of flowering of 'Seolhyang' and 'Maehyang' by low temperature-darkness treatment didn't show any difference but 'Daewang' and 'Ssanta' showed high percentage of flowering. It suggested that low temperature-darkness treatment technique can be use for improving early flowering and yield of 'Ssanta' and 'Daewang' cultivars.

  • The sensitivities to photoperiod and temperature give guidance to choose an adaptable genotype for specific area in soybean production. However, there is insufficient information about the variation of sensitivities to photoperiod and temperature with wide genetic background. We investigated the sensitivities to photoperiod and temperature using 82 soybean mini core collection lines provided by NIAS gene bank of Japan. The seeds were sown on 28 May and 4 August in 2015, 24 May and 5 August in 2016 at field in Saga, Japan ($33^{\circ}$ 14' 32'' N, $130^{\circ}$ 17' 28'' E) for the early (average photoperiod and temperature: 15.2 h and $25.1^{\circ}C$) and late (13.6 h and $27.2^{\circ}C$) sowing respectively. The plants were also grown in the growth chamber under 12 h photoperiod with three temperature regimes (day/night temperature: $25/18^{\circ}C$, $28/22^{\circ}C$ and $33/28^{\circ}C$). Emergence date, days to first flower were recorded with 10 plants in the field and 2 plants in the growth chamber for each line. The data for daily average temperatures and photoperiodic hours were collected from weather station. The days from emergence to first flower open (DEF) were varied from 23-92 (2015 and 2016) in early sowing whereas 18-68 (2015) and 18-59 (2016) in late sowing. The shortened DEF in late sowing could be caused by both short photoperiod and high temperature in late sowing. However, the accumulated temperatures during emergence to first flower open (ATEF) were less variable in comparison with DEF, suggesting the ATEF is dependent mostly on the photoperiod. The ATEF were found same between early and late sowing in some early flowering lines (e.g. $686.7^{\circ}C$ and $687.6^{\circ}C$ in HEUKDAELIPS, $728.8^{\circ}C$ and $706.3^{\circ}C$ in WILLIAMS'82) which indicated that these would be insensitive to day length. In the growth chamber experiment, the variation in both DEF and ATEF was a little greater at low temperature ($25/18^{\circ}C$) but almost same at middle ($28/22^{\circ}C$) and high ($33/28^{\circ}C$) temperatures. Since the less differences in ATEF were found between the three temperatures, it is suggested that the temperature plays only a quantitative effect on the flower initiation, and the large ATEF in some lines may indicate the stronger photosensitivity even at 12 h or longer juvenile phase. Some lines with the lowest ATEF regardless of growth conditions, such as FISKEBY V, KE 32 (ATEF: 559.6-666.5, 587.7-709.5) might lack the sensitivities to both photoperiod and temperature. The results suggested that soybean genotypes has wider variation in sensitivity to photoperiod, whereas less variation to temperature.

  • Scarf has played an important role not only as keeping warm of human body but also as accessory of clothes. These days with taking a growing interest of accessory, scarf had thrown off a subsidiary part and gradually had a leading place which guides the overall mode of fashion. Because scarf design of Korea does not get out of imitation step of foreign countries brands it is necessary to develop the scarf design which can show the cultural identity and originality of Korea in international society. Therefore in this study, I chose lotus flower patterns expressed on Buncheon pottery and Korean traditional patchwork cloth as the subject material of scarves design development, and my intention for this study is to develop scarves designs of Korean images by adding modern scenes. For that, first I researched lotus flower patterns expressed on Buncheon pottery and Korean traditional patchwork cloth. Among those materials, I selected to had been presented modern image. And by using computer design program of adobe illustrator 10.0 I designed the basic patterns of three types and developed the square scarves design and rectangle scarves design with those.

  • This study was carried out to investigate the effect of shading (50% or not) and pruning height (3cm, 6cm, and 9cm) of remained above-ground plant part on shoot emergence aspect, mortality rate, flowering and cut flower characteristics of two years old Gypsophila paniculata plants. Days to shoot emergence (80%) advanced, emerged shoot number increased and mortality rate surveyed on late October decreased in 50% shading treatment. In addition to, mortality rate decreased, as above-ground plant part was highly pruned. Blooming was earlier with highly pruning the remained above-ground pan and under non-shading condition than shading. Growth traits such flower stalk length, primary branches number, stem diameter, and cut flower yield were the best and also non-particulate rate and rosette formation rate were the lowest in pruning height of 9cm under non-shading condition.

  • A new spray carnation cultivar 'Lyra' was released by the National Institute of Horticultural and Herbal Science in 2003. A cross was made between spray cultivar 'Ballantyne' and red spray cultivar 'Chateau' in 1999. After investigation of the characteristics during four years (from 2000 to 2003), the cultivar 'Lyra' was finally selected in 2003. 'Lyra' is a spray cultivar with bright pink color for a cut flower. The main characteristics are early flowering, multi branching, fragrance and long flower stalk. Also, it has medium resistance to Fusarium wilt and 7 days vase life. To avoid calyx splitting caused by high temperature, it is recommended that this cultivar be grown over $8^{\circ}C$ at night and under $25^{\circ}C$ at day time during a flower bud differentiation period and applied with additional nitrate fertilization ($30.0kg{\cdot}10^{-1}$).
