  • The characteristics of the pigments extracted from grains of the colored barley varieties Ab2231, Mozzimugi, Lion, and Hogye 4 were studied. Extraction of the pigments from powder (80 mesh) of the barley grains was most efficient in 80% ethanol containing 1.0% HCI for 1 hr at $60^{\circ}C$. The pigments were also stable in 80% ethanol containing 1.0% HCI. Depending on the absorption spectra, maximal peak wavelength, and the ratio of $A_{440}/A_{max}$, the varieties were separated into two groups, colored naked barley (Ab2231 and Mozzimugi) and colored covered barley (Lion and Hogye 4).

  • A 25-year-old female California sea lion (Zalophus californianus) died after a history of depression, loss of appetite, weakness and weight loss. At necropsy, multifocal to coalescing, tan to white, firm nodules, ranging from 0.5 to 3 cm in diameter were observed throughout both kidneys. Renal adenocarcinoma metastasis to the liver, spleen and small intestine was diagnosed based on gross and histopathological findings. To the best our knowledge, this is the first reported case in Korea, and understanding this case will support management and diagnosis of future cases of renal adenocarcinoma in California sea lions.

  • Polymer composites are widely used as industrial materials requiring high mechanical properties. Glass fibers and fillers, which are used as a reinforcement in composites, usually have some problems such as nonuniform dispersion and poor interfacial adhesion. In this study, an acrylic acid-modified polyethylene wax was synthesized by the sequential reaction of pyrolysis of polyethylene followed by grafting with a polar acrylic acid. The acrylic acid-modified polyethylene wax was applied to polymer composites of the polyamide matrix and glass fiber reinforcement. The effect of acrylic acid-modified polyethylene wax on physical properties of polyamide based composites was thoroughly investigated.

  • Liquid ionization chamber is filled with liquid equivalent material unlike air filled ionization chamber. The high density material allow very small-volume chamber to be constructed that still have a sufficiently high sensitivity. However liquid ionization chamber should be considered for both initial recombination and general recombination. We, therefore, studied using the Co-60 beam as the continuous beam and the microLion chamber (PTW) for comparing the ion collection efficiency by Greening theory, two-dose rate method and our experiment method. The measurements were carried out using Theratron 780 as the cobalt machine and water phantom and 0.6 cc Farmer type ionization chamber was used with microLion chamber in same condition for measuring the charge of microLion chamber according to the dose rates. Dose rate was in 0.125~0.746 Gy/min and voltages applied to the microLion chamber were +400, +600 and +800 V. As the result, the collection efficiency by three method was generally less than 1%. In particular, our experimental collection efficiency was in good agreement within 0.3% with Greening theory except the lowest two dose rates. The collection efficiency by two-dose rate method also agreed with Greening theory generally less than 1%, but the difference was about 4% when the difference of two dose rates were lower. The ion recombination correction factors by Greening theory, two-dose rate method and our experiment were 1.0233, 1.0239 and 1.0316, respectively, in SSD 80 cm, depth 5 cm recommended by TRS-398 protocol. Therefore we confirmed that the loss by ion recombination was about 3% in this condition. We think that our experiment method for ion recombination correction will be useful tool for radiation dosimetry in continuous beam.

  • The purpose of this article is making investigation of the principal composition of the twin-pagodas in Buddhist temple through ornaments of a case preserving relics of Buddha in the east and west pagodas of Gameunsa temple. This research has an important meaning in clarifying that the concept of placement two Buddhas together with lotus sutra, which was only applied to Bulkuksa temple, has been extended to Gameunsa temple. And this observation gave us a clear explanation for the principal composition at the twin-pagodas in Buddhist temple plans. The author obtained the following conclusion from this article : The cases preserving relics of the Buddha for the west and east pagodas are globally in similar form as the type of a royal palace. But the different points between eastern and western can be seen on the existence of Buddhist statues on the base floor, set-up of the gate at railings, and 4 lion statues at a coner of the base floor. In the western pagoda, there are Buddha statues above the base-floor of the cases preserving relics. These Buddha statues are composed of a boy monks and angels with playing music for the praise of the Sakyamuni Buddha lecturing the Lotus sutra at YoungChui Mountain. On the other hand, in the eastern pagoda, Buddha statues on the cases preserving relics are composed of a the Four Devas and monks as a defending God of the nation of Buddha. In the eastern pagoda, one can see something that does not exist in the western pagoda, which is a gate located in railing of a case preserving the relics. This gate described the scene of the Sakyamuni Buddha entering into the pagoda of 7 treasures. In a corner of the case preserving relics in the eastern pagoda, there is another thing which does not exist in the western pagoda. This is a sculpture of a lion which symbols the seat of Lion supporting the Buddha in the Dabotap(the pagoda of 7 treasures). When we observe the form and structure, the descriptions at the railings, the gate, the shrine, the statue of a lion, and the accessories in jewelries, at the cases preserving the relics in the eastern pagoda, one can realize that they have the same combination structures between the ones at Dabotaps in Bulguksa temple and those in China as well as in Japan, all of which represent the Gyun-Bo-Tap-Pum of Lotus Sutra. Among the distribution rules in the twin-pagodas in Buddhist temple, the application of the ideal of lotus was known to be effected only to Bulguksa temple. But from the result of the present article, it is more clearly proved by applying the Gameunsa temple that the distribution theory in the twin-pagodas in Buddhist temple was in fact based on the ideal of lotus.

  • This study addresses the effective utilization of film music as learning material for language, target culture, and ethics education. Music is intertwined with language and culture, and even with ethics. This study focuses on the potential power of film music in the processes of teaching and learning in a classroom. For this purpose, five songs are selected from the soundtrack of Disney's famous animation The Lion King: "Circle of life", "I just can't wait to be king", "Be prepared", "Hakuna Matata", and "Can you feel the love tonight?", and concrete learning activities are suggested based on these. Using these five songs, gap-filling and singing-recoding tasks are proposed as listening and speaking activities respectively. Film music is also very useful in learning vocabulary, sentence structure, and grammar. Learners participate in a writing activity involving creating their own lyrics for the tunes reflecting their experiences. Next, for culture education, a teacher asks their students to discuss about, and be aware of, food culture using a specific character's song. Finally, for ethics education, a philosophy of life, natural logic, leadership qualities, and the motto Hakuna Matata("no worries") are explored and discussed through an analysis of the lyrics. The open-ended questionnaire survey is conducted. The result shows that music has a positive effect on culture and ethics education. Film music can be effective in learning a second language, target culture, and ethics.

  • Immature hybrid embryos of H. hybridum, 'Picottee', 'White Christmas', 'Eldorado', 'Origin', 'Red Lion', 'elstar', 'Crypsy' were cultured on the MS medium supplemented with various concentrations of 2,4-D, NAA, BA and TDZ. Among the treatments, NAA were more effective for the shoot regeneration and bulblet formation than other treatment. Addition of 0.5 ㎎/L NAA was effective for bulblet induction from explant Shoot regeneration was most effective on the medium with 1.0㎎/L NAA and 2.0 ㎎/L TDZ. The addition of 1.0-2.0㎎/L TDZ induced numerous shoots per explant but strongly inhibited root development when compared to 1.0-2.0㎎/L BA. When bulb scale segments of 'Star Van Holland' was incubated, bulblet formation was the most effective on MS medium with 0.5㎎/L NAA.

  • The western heraldry influenced by the style of periodic art, the lion and the eagle charges were expressed simply and laconically in Romanesque period, laconically but forcibly in Gothic period, and elegantly and elaborately in the period of the Renaissance. The symbolical character of each charge expressed in the heraldry in the process of the changes of the times can be summarized as follows: 1) The ferocious beast like the eagle or the lion in the heraldry is symbolic of a majestic appearance of sovereign's. 2) The legendary or mythical monster in the heraldry is the symbol of holding sacred the heraldry owner endowed superhuman ability from him, or the symbol of coercion or menace to the other party on the appearance of being sized with fear. 3) The domestic animals or the poultry in the heraldry are chiefly symbolic of intrepidity, bravery, sacrifice, or faithfulness, which can be supposed a subject's loyalty to his sovereign. 4) The lamb or the cross in the heraldry is the charge concerned with Christ who brought a fundamantal thought in the middles ages. So they can be said the symbol of Christianity.
