In order to convert the one ryang of Guizhi-tang into the modern weights and measures, herbs whose dose was expressed by number in Treatise on Feverile Disease of Zhongjing were measured actually. The results obtained are as follows. 1. Size of Jujubae fructus in Guizhi-tang is an average and if remove the seed, 12 Jujubae fructuses corresponds to 20g. These weights are the same as Belamcandae Rhizoma, Persicae Semen, Gleditsiae Fructus, Gardeniae Fructus and Armeniacae amarum Semen whose dose was expressed by number in Treatise on Feverile Disease of Zhongjing. If one ryang corresponds to 6.5g, 20g corresponds to three ryang. If one ryang corresponds to 15.6g, 20g corresponds to 1.3 ryang. When herbs were added in Guizhi-tang, the used weights were two more ryang. Almost unit of weights in Formulae of Zhongjing is the constantly multiplied. 2. Half sheng(升) of Pinelliae Rhizomae is 15 Pinelliae Rhizomas and corresponds to two and a half ryang. 14 Pinelliae Rhizomas are contained in 50 mL egg. 3.1 geun(斤), maximal amount of Gypsum Fibrosum and amount of one egg are the same weight supposing one ryang corresponds to 6.5g. 4. 2 ryang of Rhei Radix et Rhizoma is the 6.8 balls(碁子) of baduk and similar as 5-6 balls of baduk of Jisilchijasi-Tang. 5. General dose of Glycyrrhizae Radix is two ryang and 20mL, the size of thumb is 13g. 6. Half geun approaches the 3 flattened spoons. Consequently the presumption that one ryang in Guizhi-tang is 15.6g is wrong. One ryang is assumed as 6.5g.

This thesis mainly deals with how 'count of Ryang' was used in Joseon dynasty. Count of Ryang means how many purlins were used in the building with longitudinal section. As a result, the notion of Ryang in Joseon dynasty does not differ from now one. But the usages of that are slightly different to the present day. In Joseon dynasty, count of Ryang mainly was appeared with another word, count of Kan. Count of Kan has two meanings. One is the length, and the other is the area of building. When they used the count of Ryang combined with Kan, count of Kan had the meaning of length. By doing that, count of Ryang indicates the size of flank, count of Kan indicates the length of front. In the 19th century, count of Ryang looks similar to the past, but count of Kan shows another aspect. It did not indicate the length but the area of building. Through this study, although the usages of Ryang were different to the present, the concepts of Ryang were similar in Joseon dynasty.

Objectives : The purpose of this study was to proofread 'one ryang' in the Decoction of ${\ll}$Treatise on Cold Damage Diseases${\gg}$. Methods : I found out the ratio of maximum dose and minimum dose in this book. On the basis of the ratio, I corrected 'one ryang' in diverse decoctions. Results : In any decoction, maximum dose of medicinal medica in one decoction could not exceed four times minimum dose. Specifically, in the case that maximum dose in one decoction is sixteen ryang, it could not exceed eight times minimum dose in the same decoction. Any medicinal medica used in two decoctions or more, its maximum dose could not exceed four times minimum dose in other decoctions. On the basis of these results, it should be changed into three ryangs that are one ryang dose of 'Haematitum' of Seonbokdaeja Tang, 'Ginger' of Bujageongang Tang, Baektong Tang, Baektonggajeodamjep Tang and Senggangsasim Tang. Furthermore it should be changed into two ryangs that are one ryang dose of 'Coptidis Rhizoma' of Sohamhyung Tang, 'Ginger' of Dowha Tang, 'Ginseng Radix' of Whubaksenggangbanhagamchoinsam Tang, 'Polyporus, Poria Sclerotium, Alismatis Rhizoma, Talcum and Asini Corii Colla' of Jeoryeong Tang, 'Cimicifugae Rhizoma, Atractylodis Rhizoma Alba and Anemarrhenae Rhizoma' of Mahuangshengma Tang and 'Cassiae Cortex Interior' of Gyejigamchoryonggolmoryeo Tang. Conclusions : These results suggest that one ryang of thirteen medicinal medica such as Haematitum or Ginger of eleven decoctions such as Seonbokdaeja Tang or Bujageongang Tang should be changed into two or three ryangs.

This thesis mainly deals with how 'count of Ryang' was used in the Daehan Empire. Count of Ryang means how many purlins were used in the building with longitudinal section. As a result, the notion of Ryang in the Daehan Empire does not differ from now one. But the usages of that are different from the Joseon Dynasty, and from the present. In the Daehan Empire, count of Ryang mainly was appeared with another word, count of Kan. In the Joseon Dynasty, they used the count of Ryang combined with Kan. Count of Kan had the meaning of purlin-directional length. By doing that, count of Ryang indicates the size of flank, count of Kan indicates the length of front. But in the Daehan Empire, count of Kan, especially the beam-directional length was considered at first, and then count of Ryang. Separately they used another count of Kan meaning the area of building. By using the combined words, count of Kan and Ryang in the beam direction, they got focused on the frame of wooden structure than before.

Objectives : The purpose of this study is to determine dose of Gypsum and Natrii sulfas in Shanhanlun and Geumgyeyoryak Methods : We measured the egg size Gypsum, and Natrii sulfas 1 Seong(升), and Results : 1. The weight of GYPSUM, egg is about $48{\pm}4g$, it will end up with 104g, when applying egg gravity of 1.055 and Gypsumls weight of 2.3. 2. One Ryang(兩) is equal to 6.5g in Sanghanlun and Gumgyeyoryak, and therefore the weight of ones gypsum is equal to 1 Keun(斤). 3. Compare to a dose of Gypsum is equal to one egg in Mokbanggitang. 4. Maximum dosage of Gypsum is equal to half an egg, 8Ryang(兩) of Sanghanlun, which is 52g. 5. Daily dosage of One Keun(斤) of Natrii sulfas is 8 Ryang(兩), of sanghanlun, which is 52g, Maximum dosage of Sanghanlun is 4 Ryang(兩), which is 26g. Conclusion : As stated above we may acknowledge that a dosage of Gypsum and Narii sulfas in either Sanghanlun and Keumgyeyoryak is applicable range in practical clinic.

Objectives : This study aimed to convert into weight the dosages of flower of Daphne canescens and leaf of Phyllostachys nigra var. henonsis, whose daily dosages are likened to an object in 《Treatise on Cold Damage Diseases》. This study also aimed to understand their implications along with the previously studied gypsium and rhubarb. Methods : After reviewing documents, the dosages were converted into weight, confirmed by experiment, and their implications were considered. Results : A chicken-egg-volume of flowers of Daphne canescens is one Ryang(6.5 g) and two handfuls of leaves of Phyllostachys nigra var. henonsis is four Ryang(13 g). Each item was only used once in a decoction. Their dosages were expressed in weight respectively in 《Supplement to the Essential Prescriptions Worth a Thousand Gold》 and 《Bohenggyuljangbuyongyakbubyo》. Gypsium dosage was expressed in weight except in Daecheongryong-tang as chicken-egg-volume(16 Ryang). To liken a dosage to an object is an exception, as in the three cases above; for precision and convenience it is recommended that dosages be expressed in weight, in which case all three items fell into one of eight categories from one Ryang to 16 Ryang. Rhubarb was measured in weight, but only when using the 12-hour leaching method, four Ryang of rhubarb was cut into of 5-6 wide-go-stone-sized pieces and two Ryang into 5-6 go-stone-sized pieces. Conclusions : To liken a dosage to an object is only an exception and lacks precision and convenience; therefore dosages ended up expressed in weight, count, or volume.

Objects : The daily dose of Pinelliae Tuber in ≪Treatise on Cold Damage Diseases≫ is half seung in volume, two and half ryang in weight, and fifteen in total number. But the daily dose should be a whole number. So I found out the background of this setting and correct solution. Methods : I searched Classics of Traditional Medicine, found out the background of the daily dose setting, solution. Results : The daily dose of Pinelliae tuber in ≪Hangdi's Internal Classic Miraculous Pivot≫, ≪Bohenggyuljangbuyongyakbeobyo≫ is half seung. ≪Treatise on Cold Dameage Diseases≫ followed the same daily dose of that because it referred to these books. In ≪Synopsis of Prescription of the Golden Chamber≫, the daily dose of that is half seung, one or two seung. The half seung of the Pinelliae Tuber is thirty three mL, but the diameter is 1~1.5 cm that accurate measurement by volume is difficult. The daily dose by weight is correct considering the unity of marking of the daily dose, accuracy of measurement, the fact that Pinelliae Tuber is currently distributed by cutting. So, two ryang is correct which is thirteen gram. Conclusions : Considering the traditionality, the convenience of measurement, the daily dose of Pinelliae Tuber in the ≪Treatise on Cold Damage Diseases≫ is half seung, but considering the unity, accuracy, current state of distribution, it is correct that the daily dose of it is two ryang. It corresponds to thirteen gram.

As one of reinforcing methods for soft roadbed, the problems that mud-pumping and settlement occurred by soft roadbed, were investigated, evaluated and analyzed through installing relatively economical and efficient geosynthetics on the selected track-bed for testing. Mock-heang to Dong-ryang on the filed resting sections in the Chung-buk lines were selected as investigating the state of track and prepared field after selecting three of 1,700 spots which often make mud-pumping and requiting maintenance for that. Long curved line radiuses(R) of Mock-heang to Dong-ryang are 500m that were installed with 4 types of geosynthetics layers and one ballast layer. Installed testing cross-section is 200m totally with 40 m between places. Strength or prepared roadbed was measured to investigate the state of roadbed and track with constructing(installing) field testing sections and physical properties of roadbed soils were evaluated and analyzed. Also, mud-pumping, settlement of elastic or plastic sleeper, failure or track, wheel-loads, transverse and earth pressures were measured after installing field testing sections.
