In this study, the natural mordenite (MOR) zeolite seeds were used for the synthesis of high purity mordenite crystals. The effect of seed concentration and crystallization time on the phase purity and surface morphology of MOR crystals has also been reported. The diffraction, elemental and scanning analysis of MOR zeolite particles obtained from 100 g hydrothermal solution batch containing 3 g natural seed, hydrothermally treated at $140^{\circ}C$ for 72 h reveal the high phase-purity of as-synthesized sample having crystals of uniform size ($1-2{\mu}m$). Moreover, high seed concentration leads to the production of mesoporous MOR particles composed of needle shape primary nano crystallites. The gases adsorption performances of as-synthesized MOR particle were carried out at $25^{\circ}C$ and 0-1 bar. Surprisingly, MOR particles show good adsorption potential for $CO_2$ (97.19 mg/g) compared to other gases. Thus it confirms that high purity MOR particles can be synthesized without using any organic template which gives an advantage of separation performance at lower price.

Fabrication and electrical characterization of R. F. High-power unit capacitors were investigated to study on condition of fabrication processing for R. F. High-power unit capacitor and electrical characteristics according to addition of $ZrO_2$. The unit capacitors were fabricated using tape casting. The optimum mixture ratio of dielectrics and mixing binder for the slurry fabrication was 57.5∼60.0: 42.5∼40.0 wt%. The slurry viscosity was 4000∼5000 cps and casting state of green tape fabricated using these slurry was excellent. Optimum stacking was made by 200 kg/$cm^2$ pressure with 80$^{\circ}C$ heating. $ZrO_2$ was added to improve the electrical characteristics of unit capacitor, especially breakdown characteristics. The dielectric constant and loss factor of the unit condenser having different $ZrO_2$ amounts was not changed in the addition range of 1 to 5 wt%. Also, dielectric constant was not changed in the frequency range of 10 to 500 kHz. It was found that characteristics of resistance voltage was improved through the formation of $CaZrO_3$ and the reduction of particle size as about 3wt% $ZrO_2$ was added.

1. 연구 목적 한국의학사(韓國醫學史)의 한 분야인 식품사(食品史) 및 약물사(藥物史)는 미개척분야라 해도 과언은 아닐 정도로 연구 업적이 부족하다. 특히 식물명칭에 대한 정리는 기초학문이지만 방치되어진 것도 부인할 수 없다. 따라서 본고는 식품문화사(食品文化史)를 정리하는 과정중의 일환으로 고추의 어원(語源)을 중심으로 살펴보고자 한다. 이는 식품사(食品史) 연구에 도움이 되는 동시에 체질식이요법을 강조하는 사상의학(四象醫學)의 식품 분류에 대한 학술적 근거를 제시하는 계기로 삼고자 한다. 1493년 콜럼버스에 의해 알려진 고추는 우리 나라에 들어와 천초(川椒)대신 사용됨으로서 현재 중요한 양념이 되었다. 이에 고추의 도입과정과 호칭변화를 살펴봄으로서 현재 사전류에서 잘못 서술되고 있는 것을 시정하고, 고추가 도입된 이래 우리가 어떻게 이해하고 응용하였는 지에 대하여 문헌고찰을 통하여 의학사적(醫學史的) 입장으로 정리하는 것이 본 연구의 목적이다. 2. 연구 방법 "산림경제(山林經濟)"(1715), "임원경제지(林園經濟志)"(1827)같은 농서(農書), "물명고(物名考)"(1830), "오주연문장전산고(五洲衍文長箋散稿)"(1850) 같은 유서(類書), "훈몽자회(訓蒙字會)"(1527), "신증유합(新增類合)"(1574)같은 사전류, "지봉유설(芝峰類說)"(1614), "성호사설(星湖僿說)"(1763)같은 문집류, "흠정수시통고(欽定授時通考)"(1737), "본초강목습유(本草綱目拾遺)"(1765)같은 중국본초서(中國本草書) 등과 국내의서 등 을 통하여 고추에 대한 문헌정리를 시도하였다. 3. 연구 결과 고추가 도입된 이래 남만초(南蠻椒), 남초(南椒), 번초(番椒), 왜초(倭椒), 왜고초(倭苦椒), 왜개자(倭芥子), 고초(苦椒), 랄가(辣茄), 고쵸, 등으로 표기되어 왔다. 하지만 고추가 도입되기 전에 출간된 "구급간이방(救急簡易方)"(1489)에 '초(椒) 고쵸, 죠피'라는 기록이 나온다. 이는 천초(川椒)(초피나무)를 의미하는 '고쵸'로 보아야 한다. 후에 고추가 도입됨에 따라 의미가 변하여 고추를 의미하게 되는데 이를 정리하면 다음과 같다. 첫째, 현존하는 문헌 중 고추에 대한 최고기록인 "지봉유설(芝峰類說)"(1614)에 근거하여 고추(남만초(南蠻椒))는 임진왜란때 일본에서 도입되었다는 것이 정설이었다. 하지만 임진왜란 이전에 일본을 통하여 고추가 도입되었고 이의 개량종을 오히려 임진왜란때 일본으로 전해주었을 가능성이 높다. 둘째, 현재 대부분의 사전류에서 "훈몽자회(訓蒙字會)"(1527)의 '고쵸 쵸(초(椒))'를 고추에 대한 최초의 어원으로 보고 있으나 이는 잘못된 것이다. "훈몽자회(訓蒙字會)"의 '고쵸(초(椒))'는 고추가 아닌 매운 열매의 총칭으로 호초(胡椒), 천초(川椒), 진초(秦椒)를 의미한다. 이는 "구급간이방(救急簡易方)"(1489)의 천초(川椒)를 의미하는 '초(椒) 고쵸'에서도 확인할 수 있다. 셋째, 현재 대부분의 사전류에서 고추의 한문표기가 고초(苦草)로 되어 있으나 고초(苦椒)로 정정되어져야 한다. 초(草)(상성(上聲))와 초(椒)(평성(平聲))는 발음은 같지만 성조(聲調)가 다르며, 또한 "본사(本史)"(1787)에 고초(苦椒)와 고초(苦草)는 서로 다른 식물로 기록되어 있다. 넷째, 고초(苦椒)는 '고쵸'라는 우리말에 맞추어 만든 국자(國字)로 고추가 천초(川椒)와 비슷하지만 맵고 쓰다라는 뜻으로 사용된 것이다. 다섯째, 맵고 뜨거운 성질이 있는 고추는 냉증(冷症)을 유발시킬 수 있는 냉성(冷性)야채를 중화(中和)시키는 작용을 한다. 여섯째, 고추는 소음인 식품의 경향성을 띈 훈채류에 속한다.

In 1631 A.D. Jeong Duwon, an ambassador of the Joseon dynasty was sent to the Ming dynasty. There he met $Jo\tilde{a}o$ Rodrigues, a Jesuit missionary, in Dengzhou of Shandong peninsula. The missionary gave the ambassador a number of results of latest European innovations. A detailed description on this event was written in 'Jeong's official report regarding a message from an European country'(西洋國奇別狀啓), which is an important literature work to understand the event. Since the document was written in classical Chinese, we make a comprehensive translation to Korean with detailed notes. According to the report, the items that Rodrigues presented include four books written in Chinese that describe European discoveries about the world, a report on the tribute of new cannons manufactured by Portuguese in Macao, a telescope, a flintlock, a Foliot-type mechanical clock, a world atlas drawn by Matteo Ricci, an astronomical planisphere, and a sun-dial. We discuss the meaning of each item in the Korean history of science and technology. In particular, Jeong's introduction is an important event in the history of Korean astronomy, because the telescope he brought was the first one to be introduced in Korean history. Even though king Injo and his associates of the Joseon dynasty were well aware of the value as military armaments of new technologies such as telescopes, cannons, and flintlocks, they were not able to quickly adopt such technologies to defend against the military threat of Jurchen. We revisit the reason in view of the general history of science and technology of east-Asian countries in the 17th century.

An experiment measuring the concentration ratios of $^{137}Cs$ and $^{85}Sr$ in fish as an index aquatic animal was performed. The species was Chinese minnow (Rhynchocypris Oxycephalus), a Korean native freshwater species. Chinese minnows were reared in acryl aquarium which was 45 cm wide, 85 cm long and 50 cm high. Water in the aquarium was successively purified using filtering devices attached on the floor and the wall. Fish powder in a particulate form was supplied twice a day for feeding. After a radioactive solution was added to make the initial water concentrations approximately $0.02\;{\mu}Ci/l$ and $0.1\;{\mu}Ci/l$ for $^{137}Cs$ and $^{85}Sr$, respectively, the fish and water were sampled 10 times for a month. The concentration ratios were measured to be $0.348lkg^{-1}\sim13.906lkg^{-1}$ for $^{137}Cs$ and $0.474lkg^{-1}\sim13.089lkg^{-1}$ for $^{85}Sr$.

A about 2-month- old, mixed female cat was referred to Yeon Chang Veterinaly Clinic in Taiwan. Because this patient was wandering cat, precise history was not blown. At first admission, miosis, ptosis and protrusion of the nictitating membrane was observed in the right sided eye, and also slight miosis was found in the left sided eye. The patient was diagnosed into feline HS. Oculo-AP and injection-AP with dexamethasone were applied to this patient. Oculo-AP at Shang Jiao regions of both eyes was done for 10 minutes. In addition, injection-AP with dexamethasone (0.2 ml/acupoint) at BL01-Jing Ming, BL02-Zan Zhu and ST01-Cheng Qi. After AP treatment, prolapse of the nictitating membrane was amazingly disappeared and pupil was dilatated at session 1. Ocular findings at session 2 (one day after session 1) were maintained with nearly normal state. Accordingly, the present patient was a case with feline HS that showed favorable therapeutic effect by AP treatment.

In the present study, $CO_2$ permeation through a hydrophilic NaY zeolite membrane was studied under permeate evacuation mode for $CO_2$ single gas, $CO_2-N_2$ and $CO_2-O_2$ binary mixtures, and $CO_2-N_2-O_2$ ternary mixture. It was reconfirmed that the $CO_2$ permeation was governed by surface diffusion and the $CO_2$ selectivity was induced from blocking effect of adsorbed $CO_2$ molecules. The $CO_2$ permeance measured in permeate evacuation mode was much lower than that done in He sweeping mode, but was comparable to that obtained under feed pressurization mode. The NaY zeolite membrane showed a considerable $CO_2$ separation for $14%CO_2-80%N_2-6%O_2$ mixture : $CO_2$ permeance was about $1{\times}10^{-7}mol/m^2secPa$ and $CO_2$ selectivity was more than 10. Therefore, it was concluded that NaY zeolite membrane was one of promising membranes for post-combustion CCS process.
