At early Cheong (淸) dynasty, in medical aspect by dependent on practical studying attitude that must found a theory only by an evidence, there had been a tendancy that hoped direct research of sages' mind-eye by escaping the theory of individual classes since Geum-Won (金-元) dynasty. Yoo Chang (喩昌), born in Man-Ryeok (萬曆) 12th year of Myung (明) dynasty (A.D.1583) and dead in Gang-Hee (康熙) 3rd year of Cheong (淸) dynasty (A.D.1664). The results were as follows after studying his practical idea of medicine. 1. Yoo Chang, by recognizing the ${\ll}$Sang-Han-Ro${\gg}$ has lost its true meaning after commented by Wang Hee (王熙), Lim Eog (林億), Seong Moo-I (成無巳), etc. according to Bang Yoo-Jip's (方有執) Chak-Gan-Jung-Jeong (錯簡重訂) theory, he diversified the protocal of ${\ll}$Sang-Han-Ro${\gg}$ 397 method and arranged under Six Meridian part. (六經) 2. The theory of Sam-Gang-Jeong-Rip (三綱鼎立) can be summerized Gye-Ji (桂枝) syndrome which is the case of Wind (風) has injured Wi (衛) stage, Ma-hwang (麻黃) syndrome which is the case of Cold (寒) has injured Yeong (榮) stage, Dae-Cheong-Ryong (大靑龍) syndrome which is the case both of Wind-Cold (風寒) has injured Yeong-Wi (榮衛) stage, and there has been Sam-Gang-Jeong-Rip theory by anterior medical practitioners already but the person who formally used its Sam-Gang-Jeong-Rip term is Yoo Chang. 3. Yoo Chang seized the On Byeng (溫病) by dividing three category and in Byon-Jeung-Si-Chi (辨證施治) he influenced to many aspect of establishment of later Byon-Jeung system On-Byong (溫病의 辨證體系) pertaining to Triple-Warmer by O-Dang (吳瑭) introducing Triple-Wanner Theory. (三焦理論) 4. At Chu-Jo-Ron (秋燥論) of ${\ll}$EUi-Moon-Beop-Ryo${\gg}$, while ${\ll}$Nae-Gyeong${\gg}$ describing if humidity injury Lung, then occur a disorder in it, Yoo Chang recognized that of au tuam when dryness injure Lung there occure a disorder is it so he insisted that at this case, must use Cheong-Joe-Goo-Pye method (淸操救肺法) withherbs, pertaing to Gam-Yoo-Ja-Yoon(甘柔滋潤性) property and he invented Cheong-Joe-Goo-Pye-Tang. (淸操救肺湯) 5. Yoo Chang', so called, Dae-Gi (大氣) indicates Yang-Gi (陽氣) of chest, he insisted that man's creation and every physiological activity depends on maintainence of Dae-Gi, and it integrate Yeong-Gi (榮氣), Wea-Gi (衛氣), Jong-Gi (宗氣), Jang-Boo-Ji-Gi (臟腑之氣), Gyeong-Rak-Ji-Gi. (經絡之氣) 6. Yoo Chang's expression about partical function and character of stomach, not only bolster its theory of historical physician's expression, that is stomach is. foundatness of postnatal period, but also it has corresponding aspect with modern medicine and clinic. 7. Yoo Chang emphasized "if one cure a disease, be must understood the character of disease first and use drugs later" (先議病 後用藥) phrase about of drug usage, and his theory of Geup-Rew-Man-Joo method (急流挽舟) and three therapy of Simple Ascite (單腹腸) are all unique opinion based upon this phrase mentioned above. 8. Yoo Chang's practical idea of medicine greatly influenced to Jang Ro (張璐), Hwang Won-A (黃元御), Oh Eui-Rak (吳儀洛), Joo Yang-Joon (周揚俊), etc. and theory of Sam-Gang-Jeng-Rip (三綱鼎立), Triple Warmer Theory of On Byong (溫疫의 三焦論治), Chu-Jo-Ron (秋燥論), Dae-Gi-Ron (大氣論) etc. became important object to student of Sang-Han (傷寒) and On-Byeng. (溫病) 9. Yoo Chang's Writings has more practical meaning than other physician's, especially, later the idea of Sang-Han (傷寒) and On-Byong (溫病) greatly contributed to development of Sang-Han theory and formation of On-Byong theory.

This article is to review academic aspects of Iljae Lee Hang through Toegye Lee Hwang's comments. Iljae Lee Hang (一齋 李恒: 1499~1576) is a representative Neo-Confucian scholar in Honam area in 16th century. His Sung Confucianism was known to Toegye Lee Hwang by Gobong Gi Dae Seung and consequentially received attention from academic world. Lee Hang's Sung Confucianism, however, has hardly drawn attention since 17th century due to Lee Hwang's negative assessment. Impeaching Lee Hang's academic attitude and methods, Lee Hwang evaluated him as having many problems. Lee Hwang criticized that Lee Hang studied Neo-Confucianism with no great effort and he was so much confident to say 'Logic of the world does not deviate from this' based on Chengzi and Zhuzi's saying which was only appealing to his ideas. Lee Hang actually cited theories of Chengzi and Zhuzi and stressed self-complacency when necessary, which therefore made him fail to exhibit consistency. Iljae partly brought Lee Hwang's criticism upon himself. Lee Hwang's negative assessment is not to be literally accepted but his assessment is helpful indeed to critically examine Lee Hang's Neo-Confucianism.

In Cheon Won Gi Dae Ron(天元紀大論), Cheon(大) means Nature, Won(元) means sources, Gi(紀) is Gang Gi(綱紀) that means rules or regulations, so Cheon Won Gi(天元紀) means sources and rules of change that make Nature phenomenons. This volume treats of cause that weather change of Nature caused by, and its general rules, and presents fundamental notions and systems of measuring of 'Five elements' evolutions and Six kinds of natural factors(五運六氣)'. So named Cheon Won Gi Dae Ron(天元紀大論). This article of the research on the Cheon Won Gi Dae Ron(天元紀大論) can be divided into 3 chapters. Chapter 1 presents a theory that the principle of changes of creations' birth, groth and extinction is complished by sympathizing with Hyeong(形) of Ji(地) and Gi(氣) of Cheon(大) by rules of movement of O Un Yum Yang(五運陰陽). Chapter 2 presents theories that Tae Heo(太虛) makes Won Gi(元氣), and this Won Gi(元氣) makes the change of creations' birth, groth and extinction, and movement of O Un(五運) controls creation of nature. And treats of that 'excessive and short(太過不及)' that is made by a quality of Gi(氣) and ups and dons of Hyeong(形) controls weather of year. In Chapter 3, Cheon O Ji Yuk(天五地六) regard six and five as Yong(用). And A Cycle that movment that sympathizing with O Un(五運) and Yuk Gi(六氣) is Il Gi(一氣) as 30 years, and Il Ju(一周) as 60 years. And presents that O Un(五運) and Yuk Gi(六氣) that Gan Ji(干支) control.

I found following idea, as a result of researching his Science idea, mainly, by translation of the "$Zh\bar{a}ng$ xi $ch\acute{u}n$ $Xu\acute{e}$ $Sh\acute{u}$ ssu $hsi\acute{a}ng$ "(張錫純 學術硏究). $Zh\bar{a}ng$ xi $ch\acute{u}n$ regarded $ch\tilde{u}ng$ $ch\bar{u}ng$ $ts'\bar{a}n$ $hs\bar{l}$' (衷中參西) as the core idea of The Chinese-Western medical combination. He didn't segregate philosophy of the West from One of the Orient. He persued to harmonize each other and thought that the Western medicint theory is included in the Chinese one in many parts. besides, He recognized that it is bad to reject each other, for the medical science's purpose is to save a life, and united The Chinese-Western medicine theory, by $ch\acute{u}ng$ $ch\tilde{u}ng$ $ch\bar{u}ng$ $ts'\bar{a}n$ $hs\bar{l}$'(衷中參西) idea which refers to consult the Western medicine on the basis of the Chinese one. Medical basic theory of $Zh\bar{a}ng$ xi $ch\acute{u}n$ brought up new views of the theory : Dae-gi(大氣), gi-Hwa(氣化) theory, Nongangubgan byung juing chi(論肝及肝病證治), Eum her chijung ja bi(陰虛治重滋脾). Lim Sangeung yong(臨床應用) of Hyul Her gub(血虛及)-Hwal Hyul Hwa $\breve{u}$ bub(活血化瘀法), on the basis of classics, such as, "$N\breve{e}i$ Ching"(內經), "Chin Kue $\breve{i}$ $y\bar{a}o$ $l\ddot{u}{\bar{e}}h$, "Shen $n\acute{u}ng$ $p\breve{e}n$ $t\acute{s}{\check{a}}o$ ching"(新農本草經) etc. I'll sum up $Zh\bar{a}ng$ xi $ch\acute{u}n's$ clinical idea now He unified Sang Han(像寒)-On Byung(溫病) with Yuk Kyung Byung Jung(六經辨證) and It was noticiable to utilize a kinds of Baek Ho Tang(白虎湯). He gave a detailed description about a method of grasp the symptoms of the cause of the internal medicine diseases and pathology and, he left abundant views of theory about using remedy and experience of clinic.

This study is about the origin of Toigye's SaDanChilJeongRiGiHoBalRon (四端七情理氣互發論: theory of humanity and the relation between humanity and heaven's principle). In this study, I looked into the influences of Toigye's elders on such theory of Toigye. In this process, I introduced SimHakJangGuJipJuDaeJeon (心學章句集註大全) I obtained recently as a main material. This book was written by an uncelebrated scholar born in 60 years before Toigye. It showed "SaDanRiBalYiGiSuJi ChilJeongGiBalRiSeungJi (四端理發而氣隨之 七情氣發而理乘之)", which was as same as Toigye's study logic. Regarding the fact that such two logics were same, I traced the transferring path of such logic weighing the possibility of transferring such book or HoBalRon shown in such book while not completely neglecting an accidental coincidence. I also induced that the pro-Toigye-era also had the academic circumstance under which RiGiHoBalRon could be born even supposing an accidental coincidence. In addition, I also emphasized that such book was positioned to pioneer Toigye's neo-Confucianism in various aspects.

This study designed and developed a class using review games as a way to enhance students' interest, class participation, and class comprehension in engineering theory classes, and explored their educational effectiveness. To this end, a review game strategy based on the Creative Training Technique was established and applied to three engineering theory subjects. The types of review games include Jin-jin-ga, Bingo, Challenge Golden Bell, Finding hidden terms, and Completing initial sentences. As a result of applying this review game strategy to the classes over the past decade, students' satisfaction and lecture evaluation scores significantly increased compared to before application, and it was confirmed that students' interest in and understanding of the class increased significantly. Furthermore, this gamification class strategy can be a way to increase students' participation in theory classes regardless of their major, and can be applied to non-face-to-face online classes.

A curl distortion induced by shrinkage during stereolithography polymerization process is analyzed with the classical lamination theory. Test parts of different layer thickness and part thickness are manufactured and their deformations are measured with CMM. Curl distortion is generated by the differential shrinkage of the layers, where the total shrinkage includes the shrinkages due to solidification and the change of temperature. It is shown that the curl distortion increases exponentially with decreasing the total thickness of the part, whose smaller layer thickness induces larger curl distortion. It is verified that only a part of the total shrinkage plays a role in generating the curl distortion.

In order to improve students' interest, class participation and class comprehension in engineering theory classes, a class applying review games as Jinjinga, Bingo, etc. were designed and developed. Through applying them to three engineering theory subjects, the specific effects of the strategy on students' understanding, interest, participation, and academic achievement were analyzed and the usefulness of each review game strategy was analyzed. Analyzing class data over the past 11 years, there was a clear correlation between performance of the students in the review game and their actual grades, which was found to be greater than the negative effect of absence rate on the test performance or grades. This study also researched students' perceptions compared to other general subjects not applying the review games. The results of a survey of the students who took the review game class showed the usual amount of usual studying hours increased, the burden of examination or the amount of studying hours for preparing the exam was reduced, and the class interest and achievement significantly increased compared to other subjects in the same major.
