  • Ogchon Supergroup directly contacts with Choseon Supergroup in the northern area of Worak-san, where evidences indicating thrust-fault formed during $D_2$-deformation are observed. On footwall of thrust fault, calcite veins in Gounri Formation belonging to Choson Supergroup may be deformed during thrust faulting($D_2$). Calcite veins are parallel to axial plane cleavage($S_2$) of $F_2$ fold and truncate slaty cleavage($S_1$). Therefore, we can use deformation twins in calcite grains of the veins as a marker for inferred differential stress operated upon thrust faulting. The inferred differential stresses are estimated at 190 Mpa from K, sample. The stress from K, sample close to the contact between Ogchon Supergroup and Choseon Supergroup shows a higher value than $K_2$-$K_6$ samples, probably having an important influence upon thrust faulting. The differential stress reveal again high value at $K_7$ sample, which may suggest the presence of another thrust fault.

  • An estimation of seismic risk parameters by seismic zones of the Korea Peninsula in order to calculate the seismic hazard values using these was erformed. Seven seismic source zones were selected in consideration of seismicity and geology of Korean Peninsula. The seismicity parameters that should be estimated are maximum intensity, activity rate and b value in the Gutenberg - Richter relation. For computation of these parameters, least square method or maximum likelihood method is applied to the earthquake data in two ways; the one for the data without maximum intensity and the other with maximum intensity. Earthquake data since Choseon Dynasty is regarded as complete and estimation of parameters was made for these data using above two ways. And recently, a new method is published that estimate the seismicity parameters using mixed data containing large historical events and recent complete observations. Therefore, this method is applied to the whole earthquake data of the Korean Peninsula. It turns out that the b value computed considering maximum intensity is slightly lower than that computed considering without maximum intensity, and it becomes still lower when the incomplete data prior to Choseon Dynasty is used. In the case of the activity rates, the values obtained without maximum intensity and that with maximum intensity are similar, though they are lower when the incomplete data is used. The values of maximum intensities are usually lower when considering incomplete data. In the seismic source zone including the Yangsan Fault zone, however, the values are higher when considering the incomplete data.

  • Broadly speaking, this paper is concentrated on the trimming of the wood demanded for the palace, constructed in the 2nd half of the Choseon Dynasty. To be concrete, this is the study on the craftman and craftmanship corncerned with the trimming of the wood, its system, and terms of payment of his wages, Construction reports, financial reports, job slips, written estimates, bills for payment, and other documents in those days are examined for the study. Following conclusions have been reached through the study. 1) The operation system of whole construction office and its suboffice was very specialized and systematized from the early 19th century. 2) The craftman engaged in trimming of the wood was subdivided by work function. 3) The craftman for its first trimming, i.e. 'keojang' or 'seonjang' had been treated as a speacial labor recruited to the mid-l8th century, after that, was enrolled into the craftman. 4) A unit cost of its first trimming was firstly appropriated into the reconstruction of the Kyongwoon Palace in the early 20th century, and it was very subdivided for a personnel management. 5) Contract works were widely applied to all workers engaged in the reconstruction for an efficiency of the accomplishments.

  • The purpose of the present study is to clarify the stratigraphy and geologic structure of the Great Limestone Series by means of study on fossil conodonts and detail investigation of geologic structure. In recent years very few geologists in Korea argue without confident evidences against the age and stratigraphy of the Great Limestone Series which have been rather well established previously in most parts of the regions although it is ambiguous and has not been studied in other areas. Five type localities in the Kangweon basin where the Great Limestone Series is well cropped out were chosen for the study. Total 26 genus and 66 species of conodont were identified from 290 samples collected and treated. From the study on conodonts the age of each formations of the Great Limestone Series has been determined as follows: The Great Limestone Series of Duwibong type Duwibong limestone: Caradocian (mid-Ord.) Jikunsan shale: Landeilian (mid-Ord.) Maggol limestone: Llanvirn-Llandeilian (mid-Ord.) Dumugol: Arenigian (Ord.) Hwajeol: Upper Cambrian The Great Limestone Series of Yeongweol type Mungok (Samtaesan) : Ordovician Machari: upper Cambrian The Great Limestone Series of Jeongseon type Erstwhile Jeongseon limestone: mid-Ord. The erstwhile Jongseon Limestone formation in Jeongseon district is separated into Hwajeol, Dongjeom, Dumudong, and Maggol formations which were cropped out repeatedly by folding and faulting, but Maggol is predominant in areal distribution. Yemi Limestone Breccia bed is not a single bed but distributed in several horizons so that it bears no stratigraphic significance. The limestone bed above Yemi Limestone Breccia, which was believed by some geologists to be much younger than Ordovician, is identified to be Maggol and its age is determined to be mid-Ordovician. Sambangsan formation in Yeongweol district was believed to be Cambrian age and lower horizon than Machari formation by Kobayashi, but C. M. Son believed that it might belong to later than Ordovician and lies above the Great Limestone Series of Yeongweol type. It was identified to be upper Cambrian and lies beneath the Machari formation and above the Daeki formation, the lower most horizon of the Great Limestone Series. The age of Yeongweol type Choseon system is contemporaneous with that of Duwibong type Choseon system. The difference in lithofacies is not due to lateral facies change, but due to the difference in its depositional environment. The Yeongweol type Choseon system is believed to be deposited in the small Yeongweol basin which was separated from the main Kangweon sedimentary basin. Judging from these facts it is definitely concluded that there exists no Gotlandian formation in the regions studied. Structurally the Kangweon basin comprises five basins and two uplifted areas. These structures were originated by at least two crustal movements, that is, Songrim disturbance of Triassic and Daebo orogeny of Jurasic age.

  • 왕조시대의 궁궐은 그 나라의 문화와 예술을 대표할 수 있는 집합체이며, 궁궐은 왕과 그 일가족들의 신분과 안전을 보장하고 문화적인 생활을 영위하기 위한 공간과 한 국가를 통치하기 위한 정치적 행위의 장소로 사용되었다. 조선시대의 왕들은 그들의 사상적 배경인 성리학을 건국이념으로 삼았다. 그리고 그들 사상을 되새기고자 방지와 원도 등을 조성하였고, 이 방지는 조선시대 궁궐조경의 가장 뚜렷한 특징이다. 이러한 조선궁궐 내 지당(池塘)의 형태를 파악하고 그 변화 과정을 살펴봄으로써 원형의 복원에 대한 의견을 제시하고 지당조성에 깃든 철학을 다시 한 번 되새기는 기회가 될 것으로 생각한다. 본 연구는 조선시대 궁궐 중 그 원형이 가장 잘 보존된 창덕궁(昌德宮)을 대상으로 이전의 특정기록을 시점으로 하여 원형이 보존된 지당, 변형이 된 지당, 그리고 멸실된 지당을 찾거나 그 위치를 추정하기 위해 수행되었다. 그리고 원형이 유지되고 있는 지당, 형태가 변형된 지당, 멸실된 지당의 위치추정, 후대에 발견된 지당 등으로 구분하여 고찰하였다. 동궐도(東闕圖)상에 나타난 지당의 총 개수는 17개소이며, 원형이 유지되고 있는 지당은 4개소, 형태가 변형된 지당은 5개소, 멸실된 지당은 8개소이며, 새로 나타난 지당은 2개소로 고찰하였다. 그리고 도출된 결과로 복원 및 복구의 의견을 제시하였다. 오늘날처럼 지식과 정보가 순간 이동되고 문화와 국경의 구분까지도 모호하게 혼합되어 가는 상황에서 우리의 마음속에 공통적으로 내재되어 이어지는 전통 문화의 하나인 방형 지당을 현 시점에서 점검하고자 본 연구가 수행되었다.

  • To study the clothing names has been one of the research subjects in the history of clothing since the name could be the basic tool to understand the clothing. In the past, the name of clothing were used in Chinese character which is hieroglyphic. Each character of Chinese has special meaning. They had been changed into Korean after Korean characters were invented. During the period when they were changed into Korean, some of them retained the original meaning while others widened the original meaning. Some of them even translated into totally different meaning.

  • Compared to Early Chosun Dynasty, the spatial structure of most local Eupseongs of Korea had a standardized change with the expansion and spread of the Rye-hak(禮學:a study of confucius Rite). Meanwhile in the process of rebuilding Eupseongs there was a tendency of relocation of the local government offices(官衙) and its attached facilities in terms of functions and use. Although it was PyeongSanseong Miryang Eupseong had an unreasonable spatial structure locating Gaeksa(客舍; accommodation house for visitors) in the middle of the local government office complex, and Dongheon(東軒;main office building) in the east of it before the Japanese Invasion of Korea in 1592. However with the reorganization of spatial Structure of local Eupseongs after the Japanese invasion Gaeksa was moved to the foot of Adongsan where commanded a fine view of river. Dongheon was moved to the center of Eupseong for the effective management of its auxiliary organizations. It was because road system and administrative efficiency had a serious effect on deciding the location of the local government office and its attached facilities. After the Japanese invasion Hyangchoeng(鄕廳), having been out of Eupseong, also was moved to the independent location within Eupseong separate from Dongheon and Gaeksa. It seemed to take into account the autonomy of Hyangchoeng. Dongheon, Gaeksa, and Hyangchoeng which are the crucial facilities of Milyang Eupseong were arranged at each angular point of big triangle. In order to enhance the administative efficiency, the attached administrative facilities were arranged surrounding Dongheon and Hyangchoeng. The spatial structure of Milyang Eupseong in the late Choseon dynasty was of great difference from that of uniformly organized system of early Choseon Period. It was because the development of administrative function, the pursuit of efficiency, and commercial progress had a great impact on the change of urban space.
