건물에 작용하는 진동하중은 구조물 자체의 성능에 영향을 미칠 뿐만 아니라 거주하는 사람이나 작업기계 동에 나쁜 영향을 가져올 수 있다. 본 연구에서는 이러한 진동에 대한 영향을 평가하는 국내외의 기준에 대하여 고찰하고 다양한 하중과 주파수 대역에서 실험이 가능한 대형지진모사 실험센터에 대한 진동영향 평가를 수행하여 사용성 저하 여부를 확인하였다.

We report a case of a sclerosing hemangioma of the lung with increased size during follow up, a rare benign neoplasm of the lung. A 32-year-old woman had round increased opacity in right upper lobe on posteroanterior chest radiograph. That lesion has grown slowly over four years. Computed tomographic scan showed a well circumscribed lung mass in medial aspect of right upper lobe. Radiological differential diagnosis for the lesion included inflammatory pseudotumor, atypical carcinoid, lung cancer and localized fibrous tumor of pleura. Nonspecific findings were shown by the bronchoscopy and percutaneous transthoracic needle aspiration. Anterior and apical segmentectomy was carried out and the lesion was pathologically diagnosed as sclerosing hemangioma of lung.

Oryoungsan which first recorded in Sanghanron, the clinical medical book consists of treating acute febrile disease according to its change, is one of the frequently used oriental medicines. these days, it has been prescribed in symptoms accompanied by edema mostly. therefore it is easy to consider it as a type of diuretics. In Sanghanron it was originally used in the symptoms of perspiration, decreased urine volume, thirsty, flatulence, these symptoms indicate loss of body fluid and the prescription which orders "taking warm water sufficiently" supports this. On this background, it is supposed that Oryoungsan treats dehydration after providing water and electrolytes. To consider that herbal medicines consisted of Oryoungsan make electrolytes go out of the body, The healing mechanism of dehydration doesn't meet this. Because Oryoungsan was used in condition of fever or in similar condition, it is more resonable to understand that restoration of increasing blood flow to the subcutaneous venous plexus regulating body temperature in febrile condition into body circulation, resulting into maintaining main blood volume and into treating decreased urine volume and thirsty is Oryoungsan's function in the dehydration or febrile condition. That is, symptoms are decreased or disappeared through restoring unbalance of internal body fluid. The other target is pain controls, especially chronic headache, facial pain and trigeminal neuralgia, it is suggested that the funciton of pain control of Oryoungsan is related to 5-HT(5-hydroxytrypamine), nerve transmitter in the endogenous analgesic system. Moreover it is also suggested that Oryoungsan is relate to 5-HT, considering the fact that gastroparesis, a symptom of cyclic vomiting syndrome treated with 5-HTID receptor agonist is similar to the 'bi(??)', symptoms appeared in the Oryoungsan-related disease.

이 연구는 Free workover forward 동작의 이상적인 지도방법과 마루와 평균대에서 좀 더 안정적이고 발전되는 기술동작을 배우는 데 기초자료로 제공함에 그 목적을 두었다. 이 연구의 목적을 달성하기 위해서 H대학의 여자 체조 선수 3명을 임의 추출하여 운동학적인 변인을 분석한 결과 다음과 같은 결론을 얻었다. 마루운동에서 제자리 한발 몸펴 앞공중 돌기 동작을 연기하는데 1국면에서 슬관절과 고관절을 빠르게 신전시켜 회전속도를 증가시켜야하고 3국면에서 4국면까지 수직상승 탄력을 이용하여 신체를 높이 투사시켜 회전속도를 빠르게 하며 5국면에서 여유있는 착지를 이루는 자세가 가장 바람직한 동작임을 알 수 있다. This study has been aimed at providing an ideal instructive method of 'Free workover Forward′ motion and basic data for the learning of a more stable, developed, and skilful motions on the floor as well as balance beam. In order to achieve such an aim of this study, three female champions of physical exercise were employed at random from H University as the object for the research and analysis of kinetic variable factors as resulted in as follows. 1. It was learned that the change in the factor of time variance from phase 1 throughout phase 3 should quicken the time consumed and when remaining in the air the rotation force of the moving body should be accelerated in short moment. It was desirable that air-remaining time for the body should be raised by moving reaction of sposeting leg and the swing of kick should be big and quick. 2. When the location of the body center should move quickly the horizontal and vertical locations at phase 2, and the body was projected in the air at phase 3, the hips should be extended, the horizontal location should be small, the vertical location should be big, the height of remaining in the air should be raised so that landing posture could be taken with enough allowance of time due to increased time for remaining in the air. 3. when the body center passed the horizon as the speed variation of the body center at phase 1 throughout phase 3 raised the vertical speed with the application of the vertical speed and the reaction of the knees. It was known that a stable motion was made through the flexion of knees as it made vertical at phase 5 upholding quickly the moving body. 4. change of angles of the articulations yielded the greatest change of angles at the knees at phase 1 throughout phase 3, and before the rotation of the body, the arch posture motion was shown to be desirable to take a stable posture through straightening thy vertical posture by quick rotation force from too much extension of the knees. summarizing the above, in the performance of the motion of stretching the body with one step at the same position and rotating in the air, the rotation speed should be increased at phase 1 by extending rapidly the knees and hips at phase 3 throughout phase 4 the rotation speed should be quickened by projecting highly the body with the application of elasticity in vertical uprising and then forming an allowable landing was desirable at phase 5.

김덕묵,민형식 단국대학교 1998 論文集 Vol.33 No.-

A Silver­alkali manganese oxide, Ag­M_2 MnO_3 has been prepared from Mn­salt and AgNO_3 by reacting with excess alkali hydroxide. The structure of the product have been determined by powder X-Ray diffraction, SEM, and chemically analysis. Performance and characteristics of the silver­alkali manganese oxide catalysed ozone decomposition are described in relation to the preparation conditions and the silver contents. This alkali manganese oxide catalyst showed the highest capacity in the other Ag­Mn­oxide system.

Tooth development is usually described in four stages such as bud stage, cap stage, bell stage and crown stage. Exact time of appearance of tooth primordia is different among reports, and up to now there is no timetable regarding initial tooth development. To understand the congenital malformations and other disorders of the orofacial region, there is need to establish a standard timetable of early tooth development. Till now, studies on the tooth development were mainly on later fetuses, and only few reports on early stage. Also, there were no reports on the time when bud stage turns to cap stage, and cap stage to bell stage. In this study, external morphology of face and the early development of the tooth, and transition of bud stage to cap stage, cap stage to bell stage were studied using 27 staged human embryos and 9 serially sectioned human fetuses. the results are as follows : 1. Mandibular region was formed by union of both mandibular arch at stage 15, and maxillary region by union of maxillary arch, medial nasal prominence, and intermaxillary segment at stage 19. 2. Ectodermal thickening which represents the primordia of tooth appeared in mandibular region at stage 13, and maxillary region at stage 15. 3. Bud stage began from mandibular primary central incisor at stage 17, and maxillary primary central incisor at stage 18. And the sequence of appearance was in the mandibular primary lateral incisor at stage 19, maxillary primary lateral incisor at stage 20, mandibular primary canine at stage 22, maxillary primary canine and primary first molar at stage 23, madibular primary first molar and maxillary primary second molar at 9th week, and mandibular primary second molar at 10th week of development. 4. cap stage began from the primary anterior teeth at 9th week, and primary second molar still had the characteristics of cap stage at 12th week of development. 5. Transition to bell stage started from the primary anterior teeth at 12th week, and primary second molar started at 16th week of development. 6. Trnasition to crown stage started from primary anterior teeth at 16th week, and primary second molar at 26th week of development.

The research described in this paper was conducted to estimate the level of air, water and soil pollution, and plans for environmental conservation in Chinju city. The characterizations of air, water and soil pollution in Chinju were investigated during the period of September and November of 1997. The concentrations of air and soil pollutant in Chinju were lower than a metropolitan areas or environmental standard. The pollution level of water quality were higher Keong-Ho and Yang-Chen river compared with Duck-Chen river.
