In high temperature ceramic glazes, a stable range of pink-red colors that produced $Cr_2O_3-SnO_2-CaO-SiO_2$ pigments were factored by Cassiterite($SnO_2$) and Malayaite($CaSnSiO_5$) by $Cr_2O_3$. The experiment examined the influence of $CrCl_3$, a Sn-Cr substitution added with a mineralizer ($H_3BO_3$), as a chromophore in pigments. The experiment also studied the effect of $H_3BO_3$ (2 wt%) when added to malayaite($CaSnSiO_5$) to see if the crystalline reaction will increase. $Cr_2O_3$ was also substituted with $CrCl_3$ in order to prove how much influence $CrCl_3$ had on the $H_3BO_3$. Malayaite and cassiterite were the basic compound materials and the experiment was conducted both with and without mineralizers (2 wt% of $H_3BO_3$). Each compound was synthesized at 800, 1000, 1200, 1300, 1400, $1500^{\circ}C$ for 2 h. Synthesized pigments were analyzed by XRD, FT-IR and UV-Vis. The temperature variation produced two crystal phases that showed the different engaging effects of Cr oxidation. $CrCl_3$ produced a better effect on the malayaite crystal phase, resulting in a more defined pigmentation of the pink-red coloration compared to $Cr_2O_3$.

Objective: The purpose of this study is to compare the original texts with quotations in 16 Kinds of Cough Part in Haesu Chapter of Dong-Yi-Bo-Gam and to find out the ideas of Huh Jun(許浚, 1546-1615; the author of Dong-Yi-Bo-Gam) in there. Methods: I compared the original texts with quotations in 16 Kinds of Cough Part in Haesu Chapter of Dong-Yi-Bo-Gam. Results: 1. There is only one quoted sentence which perfectly matches with original text in 16 Kinds of Cough Part in Haesu Chapter of Dong-Yi-Bo-Gam. The other sentences are all modified while they are quoted by Huh Jun, at least one word. 2. The arrangement order of 'medical effect', 'consisting medicines and their dosages' and 'doctrine in application' were rearranged following the form of Dong-Yi-Bo-Gam when being quoted. 3. In cases of reciting the text, Huh Jun tries to clarify the original source of the context. However, instead of using original quotations he recited rephrased quotes from other sources. 4. Huh Jun cites from not only cough parts of other texts but also asthma(喘症) or heat(積熱) parts. 5. Titles of original text books are recorded in the end of all sentences of Dong-Yi-Bo-Gam, but there are a few wrong titles recorded. Conclusion: In consideration of the above-mentioned, the Dong-Yi-Bo-Gam is not the mere collection of various Oriental Medical books, but the Classic of Oriental Medicine to hold Huh Jun's own opinion.

DongUiBoGam(東醫寶鑑) is Joseon's classic medical text that has great significance in the medical history of Korea. However, the context of the treatments of accupuncuret&moxibustion in the book are hardly studied. This study is for the purpose of examining the treatments of accupuncuret&moxibustion in DongUiBoGam(東醫寶鑑), and it starts with studying the accupuncuret&moxibustion part of DongUiBoGam(東醫寶鑑)'s NaeGyeong Chapter(內景篇) for starters. Through this study, the following could be known. 1. In DongUiBoGam(東醫寶鑑)'s NaeGyeong Chapter(內景篇), it is written that it quoted many various books, but actually, most of the parts are quoted from LouYing(樓英)'s YiXueGangMu (醫學綱目). 2. LouYing(樓英)'s YiXueGangMu(醫學綱目) is a work of the Ming Dynasty, which is when China's study of accupuncure&moxibustion was completed and many books on accupuncure&moxibustion were published. 3. However, in DongUiBoGam(東醫寶鑑), it mainly quotes from YiXueGangMu(醫學綱目), instead of these professional acupuncture&moxibustion texts. This is because this book is a comprehensive medical text with various medical theories, which share the same flow with DongUiBoGam(東醫寶鑑), and at the same time, it organized the treatments of accupuncure&moxibustion in a big scale in various ways.

We describe here the mass death of predatory carp, Chanodichthys erythropterus, in Korea induced by plerocercoid larvae of Ligula intestinalis as a result of host manipulation. The carcasses of fish with ligulid larvae were first found in the river-edge areas of Chilgok-bo in Nakdong-gang (River), Korea at early February 2016. This ecological phenomena also occurred in the adjacent areas of 3 dams of Nakdong-gang, i.e., Gangjeong-bo, Dalseong-bo, and Hapcheon-Changnyeong-bo. Total 1,173 fish carcasses were collected from the 4 regions. To examine the cause of death, we captured 10 wondering carp in the river-edge areas of Hapcheon-Changnyeong-bo with a landing net. They were 24.0-28.5 cm in length and 147-257 g in weight, and had 2-11 plerocercoid larvae in the abdominal cavity. Their digestive organs were slender and empty, and reproductive organs were not observed at all. The plerocercoid larvae occupied almost all spaces of the abdominal cavity under the air bladders. The proportion of larvae per fish was 14.6-32.1% of body weight. The larvae were ivory-white, 21.5-63.0 cm long, and 6.0-13.8 g in weight. We suggest that the preference for the river-edge in infected fish during winter is a modified behavioral response by host manipulation of the tapeworm larvae. The life cycle of this tapeworm seems to be successfully continued as the infected fish can be easily eaten by avian definitive hosts.

Objective: To evaluate soft- and hard-tissue changes in the mandibular angle area after the administration of botulinum toxin type A (BoNT-A) injection to patients with masseteric hypertrophy by using three-dimensional cone-beam computed tomography (3D-CBCT). Methods: Twenty volunteers were randomly divided into two groups of 10 patients. Patients in group I received a single BoNT-A injection in both masseter muscles, while those in group II received two BoNT-A injections in each masseter muscle, with the second injection being administered 4 months after the first one. In both groups, 3D-CBCT was performed before the first injection and 6 months after the first injection. Results: Masseter muscle thicknesses and cross-sectional areas were significantly reduced in both groups, but the reductions were significantly more substantial in group II than in group I. The intergonial width of the mandibular angle area did not change significantly in either group. However, the bone volume of the mandibular gonial angle area was more significantly reduced in group II than in group I. Conclusions: The repeated administration of BoNT-A injections may induce bone volume changes in the mandibular angle area.

Biaxially oriented polyethylene terephthalate copolymer(BO - PET)film laminated aluminiums have been applied for chip condenser case. The BO PET film is characterized by high molecular which gives high corrosion resistance, good adhesion and high heat resistance. The higher orientation lowers formability of the film. So, optimum orientation has to be controlled during the laminating process. And to confirm the adhesion between BO PET and aluminium and to guarantee the formability of PET laminated aluminums, we have controlled the chromium oxides weight on the aluminium and laminating condition ( laminating temperature, soaking temperature and lag time after nip roll and quenching conditions) This paper discusses the effect of the laminating conditions on the formability of laminated aluminums. As results, it is clear that the orientation of the BO PET film decreased with an increase in the strip temperature. When the film temperature is over the melting point of the film, its orientation drastically decreased.

Nanocrystalline $GdBO_3:Eu^{3+}$ was prepared by a hydrothermal method. The as-synthesized powders were spherical shaped agglomerates of nano particles. The luminescent properties were compared with samples synthesized by conventional solid-state reaction method. Both the photoluminescence intensity and chromaticity were improved and a red-shift in the CT band was observed for the hydrothermally synthesized samples.
