We study the amorphous In-Ga-Zn-O thin-film transistors (TFTs) properties under monochromatic illumination ($\lambda=420nm$) with different intensity. TFT off-state drain current ($I_{DS_off}$) was found to increase with the light intensity while field effect mobility ($\mu_{eff}$) is almost unchanged; only small change was observed for sub-threshold swing (S). Due to photo-generated charge trapping, a negative threshold voltage ($V_{th}$) shift is also observed. The photofield-effect analysis suggests a highly efficient UV photocurrent conversion in a-IGZO TFT. Finally, a-IGZO mid-gap density-of-states (DOS) was extracted and is more than an order lower than reported value for a-Si:H, which can explain a good switching properties of the a-IGZO TFTs.

In this thesis, I intend to study the translational and clinical interpretation through the theory of Ja-Yeol, and reached the following conclusions. 1. Liver-Heat-Disease due to absess of the function of expelling and lifting off, that Liver-Yang cannot lift up to upper-warmer, and stagnate liver. I think the symptoms of yellowish urine, abdominal pain, somnolence, fever belong to the syndrome of 'Gi-Bun(氣分)', and the symptoms of ravings with surprising, distending pain of hypochondrium, restless involuntary movement of the limbs, unable to lie flat belong to the syndrome of 'Hyeol-Bun(血分)'. 2. Heart-Heat-Disease due that 'Eum-Gi(陰氣)' in heart cannot lay down and reach to stagnate at heart, inner part. I think the symptoms of unjoy, acute cardiac pain, fidgetiness, well-nausea, headeche, reddish face, anhidrosis, etc. reveal with Heart-Heat-Disease. 3. Spleen-Beat-Disease due that 'Eum-Gi' in spleen cannot lay down and Yin of spleen changs heat. I think the symptoms of heaviness of head, cheek pain, fidgetiness, cyanosis, well-nausea, fever, not to let flex and reflex with back pain, diarrhea with abdominal pain, left and right cheek pain reveal with Spleen-Heat-Disease. I think symptoms of fever, diarrhea with abdominal pain belong to the syndrome of Yin-exhausion. 4. Lung-Heat-Disease due to that 'Eum-Gi' in lung cannot lay down. When 'Wi-Gi(衛氣)' stagnates at external part, I think, the symptoms of intolerance to wind and cold, yellowish fur, fever reveal. When Wi-Gi stagnates at lung, inner part, I think, the symptoms of dispnea with cough, pain on chest and back, unable to breath deeply, hydrosis and chilling reveal. 5. Kidney-Heat-Disease, in that the symptoms of back pain, leg aching, extreme thirst and frequently drink, fever, pain and stiffness of nape, cooling and aching leg, heat on plantar pedis, not trying to speak reveal is regarded external heat disease of 'Tai-Yang-Gyeong's(太陽經)' disease that asthenic fever open 'Tai-Yang-Gyeong' and lift by not enough of 'Yang-Gi(陽氣)' lifeing up from Kidney space, the water space of five elements.

The Sa-Ahm monk, who was believed to have existed in the middle of Cho-Seon Dynasty in Korea, have created an original Sa-Ahm's acupuncture method and written down, "Book of Sa-Ahm's 5 Element Acupuncture Method" using not only laws of creation and suppression in 5 element theory but also its main and other connected meridians according to the daignosis of visceras and bowels. Also the written time and background of its theory have not been known, and after obtaining Ji-San's book on Sa-Ahm's acupuncture method, I studied on them. The results are as follows : 1) The treatment chapter of Book of Sa-Ahm's 5 Element Acupuncture Method was written down by Sa-Ahm himself, and the chapter for Medical Experience was found to be written down by Ji-San. 2) It seemed that Sa-Ahm adopted the main ideas of "Eui Hak Jeong Jon(醫學正傳)" for the section of physiology, pathology and classification of disease symptoms the contents of which covered 40 of 43 parts, and the ideas of "Dong Eui Bo Gam(東醫寶鑑)" for YunGi treatise(運氣篇), and SangHan part(傷寒門) in classification of diease symptoms was intensified by the ideas of "Eui Hak Ip Moon(醫學入門)", and the contents of apoplexy, diseases characterized by acute diarrhea and vomiting, beriberi, diseases of oral cavity were intensified by the ideas of "Chim Ku Kyeong Hearn Bang(鍼灸經驗方)". 3) The written date of the Book of Sa-Ahm's 5 Element Acupuncture Method has been established as 1644 AD(22nd year of In Jo king of Cho-Seon Dynasty) after studying preface, contents and acknowledgement of Heo Im's "Chim Ku Kyeong Hearn Bang(鍼灸經驗方)". 4) The philosophic background of "Sa-Am Acupuncture Method(舍巖鍼法)" seems to be derived from the theories of "I Ching(周易)" and Yin Yang 5 Element Theory(陰陽五行學說), and to be influenced by such medical scholars as Tan Ke(丹溪), Woo Bak(虞搏), and Heo Im(許任).

The topic of this study is the translation of "Byun Jeung Rok Vol.XI(辨證錄十一卷)". Byun Jeung Rok is a complete book of medicine which was written by Jin Sa tak(陣士鐸) in the early years of the Ching dynasty. Of this, the eleventh volume is composed of 6 disease-patterns(病證) and 41 subtopics. The organized characteristics of "Byun Jeung Rok(辨證錄) Vol.XI" is as follows. Chapter 1 refers to the symtom, agent and prescription of Hysterorrhea(帶下病). It explains five color Hysterorrhea; white, red, black, yellow and blue. Chapter 2 refers to the symtom, agent and prescription of Oligemic Menoschesis(血枯). It explains two cases of Menoschesis. Chapter 3 refers to the symtom, agent and prescription of Metrorrhagia(血崩). It explains eight cases of Metrorrhagia. Chapter 4 refers to the symtom, agent and prescription of Dysmenorrhea(月經不調). It explains fourteen cases of Dysmenorrhea. Chapter 5 refers to the symtom, agent and prescription of Infertilitas(不姙). It explains ten cases of Infertilitas. Chapter 6 refers to the symtom, agent and prescription of Hyperemesis(惡阻). It explains two cases of Hyperemesis. Obviously the Byun Jeung Rok(辨證錄) is one of the very important texts in the oriental medicine. But there is no exact Korean translation, so I study this six chapters and translate them into Korean. Finally, I hope this thesis can be an aid of development in the knowledge informatization of Korean medicine.

A study was carried out to compare the food cultures among Korea (Chosun dynasty), China (Ming, thing dynasty) and Japan (Muromachi, Edo era) from 14 century to 19 century. For this study, geographical environments, historical background with the times were researched and also bibliographies related on food cultures were compared among these three countries. There were special geographical environments in three countries upon their territories and geographical features. Historically, in those era, the livelyhoods of the common people in three countries were difficult considerably because of the disturbances of war in the inside and outside of the countries. But the food cultures of three countries were changed owe to introduce the new western culture and institutions. And also there were numerous bibliographies related on food culture which were published from 14C to 19C in Chosun dynasty, Ming and Ching dynasty, and Muromachi, Edo era. They were shown to be the most in Japan, and order of China and Korea followed them. The bibliographies of Ming and thing dynasty showed less than those of Edo era for considering their population and territory, comparatively. In Japan, the biliographies related on food culture of Edo era was given the term of the age of cookery books. It was thought to be resulted from that the peoples of Japan were concerned about cooking and had more chances to contact foreign culture earlier than other country.

Objective: The objective of this experiment was to investigate the effects of different colors produced by light emitting diode (LED) on Brown Tsaiya ducks. Methods: A total of 144 female Brown Tsaiya ducks were randomly allocated into three individual cage rearing chambers with different LED illumination colors as treatments. Three different treatments were: i) white color, ii) blue color, and iii) red color. The experiment periods were from ducks 21 to 49 weeks of age, determined traits included i) egg laying performance, ii) feed intake, iii) egg shell breaking strength, iv) egg shell thickness, v) egg Haugh unit, vi) egg weight, vii) serum Estradiol and Progesterone concentration, and viii) behavior pattern. Results: The results indicated that when compared with white and blue color, red color could stimulate ducks sexual maturation and raised the egg laying performance. The red light group was also observed to have the highest feed intake among three treatments. The blue treatment had the lowest egg shell breaking strength and the highest egg weight among three treatments, nevertheless, no significant difference was observed among three treatments on egg shell thickness and egg Haugh unit. The red light group had higher serum estradiol concentration than the white and blue groups, but no significant difference among treatments on the serum Progesterone concentration was found. The results of behavior pattern indicated that red light group showed more feeding and less resting behavior compared to the blue light group. Conclusion: We found a potential of applying red light illumination in the indoor laying duck raising system with positive results on egg laying performance and acceptable egg weight, equivalent egg qualities compared to white and blue light.

We studied both the wavelength and intensity dependent photo-responses (photofield-effect) in amorphous In-Ga-Zn-O (a-IGZO) thin-film transistors (TFTs). During the a-IGZO TFT illumination with the wavelength range from $460\sim660$ nm (visible range), the off-state drain current $(I_{DS_off})$ only slightly increased while a large increase was observed for the wavelength below 400 nm. The observed results are consistent with the optical gap of $\sim$3.05eV extracted from the absorption measurement. The a-IGZO TFT properties under monochromatic illumination ($\lambda$=420nm) with different intensity was also investigated and $I_{DS_off}$ was found to increase with the light intensity. Throughout the study, the field-effect mobility $(\mu_{eff})$ is almost unchanged. But due to photo-generated charge trapping, a negative threshold voltage $(V_{th})$ shift is observed. The mathematical analysis of the photofield-effect suggests that a highly efficient UV photocurrent conversion process in TFT off-region takes place. Finally, a-IGZO mid-gap density-of-states (DOS) was extracted and is more than an order of magnitude lower than reported value for hydrogenated amorphous silicon (a-Si:H), which can explain a good switching properties observed for a-IGZO TFTs.

Background: The prevalence of esophageal cancer (EC) with second primary cancers (SPC) is increasing worldwide. This study was aimed to understand the clinical features of EC patients with SPC in the Taiwanese population. Materials and Methods: Clinical and laboratory data for 180 EC patients with or without SPC were collected between January 2009 and December 2013. Information on treatment approaches, location of SPCs and ABO blood type were also collected and stratified. Results: The most common SPC in EC patients was hypopharyngeal cancer, followed by laryngeal cancer and hepatocellular carcinoma in our study. Malignancies of colon, prostate and lung were also found. There was a significant higher portion of blood type A in the EC patients with SPC compared with those without (42.4% vs 19.5%, P=0.006). Conclusions: The frequency and SPC site distribution and blood type A should be considered in clinical evaluation of EC patients with a high risk of developing SPC in the Taiwanese population.

Objective: The sperm acrosome reaction is a $Ca^{2+}$-dependent exocytotic event that is triggered by adhesion to the mammalian egg's zona pellucida. Previous studies suggested a role of $Ca^{2+}$ channels in acrosome reactions. This study was conducted to investigate the T-type calcium channel is operated in acrosome reaction of human spermatozoa. Method: Human semen samples were obtained from healthy donors with normal criteria. The spermatozoa were divided into five groups: Group 1 were non-treated as a control; Group 2 where spermatozoa were exposed to 5 ${\mu}M$ $Ca^{2+}$ A23187 $(Ca^{2+}i)$; Group 3 where spermatozoa were exposed 5 ${\mu}M$ $Ca^{2+}i$ and mibefradil; Group 4 where spermatozoa were exposed 5 ${\mu}M$ $Ca^{2+}i$ and nifedipine, and Group 5 where spermatozoa were treated with 5 ${\mu}M$ $Ca^{2+}i$ and both of mibefradil and nifedipine. Spermatozoa in all groups were retrieved after incubation for 15 and 30 minutes at $37^{\circ}C$. After staining with PSA-FITC, fluorescence was observed under a fluorescence microscope, and AR was evaluated on a total>100 spermatozoa/side. Result and Conclusion: We observed on acrosome reaction inhibition rate in human spermatozoa the various of concentration of mibefradil, nifedipine. Maximum response was noted with 1.0 ${\mu}M$ mibefradil and the decrease of acrosome reaction inhibition rate 45%. Nifedipine in acrosome reaction inhibition rate was only about 25%. The $Ca^{2+}i$-induced AR of spermatozoa was significantly suppressed by mibefradil. Incidence of the suppression was depending on concentration of mibefradil. Results from the present study suggest that the human spermatozoa possess T-type channel. The observation that reversible inhibitor of T channels in male germ cells provides a new mechanism of contraceptive action.

선반입은 I/O 성능 향상을 위해 널리 사용되는 기법 중의 하나이다. 하지만 어떤 참조패턴에 대해서는 선반입을 수행하면 오히려 전체 수행시간이 증가하는 경우가 보고된 바 있다. 본 논문은 기존의 선반입 기법에 쉽게 적용될 수 있는 프레임 IPRP(Improving Prefetching Effects by Exploiting Reference Patterns)를 제안한다. IPRP는 참조패턴을 자동으로 탐지하고 기존의 선반입을 참조패턴의 특성에 따라 조정하여 개선하고자 한다. IPRP를 리눅스 미리 읽기 선반입에 적용한 성능평가에서 리눅스 미리 위기 선반입이 수행시간을 $40%{\sim}70%$ 정도 증가시키는 악영향을 발휘할 때 IPRP를 적용할 경우 악영향을 완전히 방지했다. 리눅스 미리 읽기 선반입이 성능 향상을 가져오는 경우에도 리눅스 미리 읽기와 유사한 성능을 가전 왔다. 이 결과를 통해 IPRP가 기존의 선반입을 효율적으로 보완 및 개선할 수 있음을 알 수 있다.
