Phage血球凝集反應에 必要한 phage量에 對하여

李賢澤 中央醫學社 1967 中央醫學 Vol.12 No.3

The author has investigated the effect of phage dose on phage hemagglutination. For this experiments, the klebsiella pneumoniae type 2, klebsiella phage and goat red cells were used and obtained the following results. For producing of the cold and warm phage hemagglutination, the more phage dose, in adsorption tube, than 106/ml and 108/ml was necessary respectively and, in the less dose of phage than that, phage hemagglutination was not produced even though higher concentration of serum was used. For producing of phage hemagglutination in the presence of 1:800 of stock serum of which K value is about 190min.-1, the more adsorbed phage particles, per sensitized red cell, than average 100 were necessary.

This study deals with the degree of enclosure on the Court Space in 'Suh-Won' that has warious perceptual composition elements. 1. The size of Court Space in which we can read the complexion of others and easily understand every behavior of them is similar to that of the 'Madang' in the Korean traditional houses. 2. The angles of elevation are within the range of suitable enclosure as going from the center of the court Space to 'Kang-Dang' and the space -from the center of the Court Space to 'Kang-Dang'- is restricted and surrounded. It is also within the range of the least enclosure as going from the center of the Court Space to the 'Mun-Ru'. 3. The degrees of enclosure based on the horizontal angle are within the degree we can perceive the objects of structure easily. 4. The degree of enclosure based on the ratio D/H is increased as approaching from 'Mun-Ru' to 'Kang-Dang'. The distance as approaching from 'Mun-Ru' to 'Kang-Dang' is changed from social distance to personal distance. To conclude this the Court Space in 'Suh-Won' represents the hierarchical system with variety and the degree of enclosure and the size of space are within the range of human scale.

To reconstruct the chronic bony exposure with extensive soft tissue defects of the lower extremity, the muscle flap coverage is preferred to cutaneous flap transfer. 7 lower extrmities in 6 patients of postburn wide bony exposure of lower extremity accompanying osteomyelitis were successfully reconstructed by various types of muscle flaps and proper administration of sensitive antibiotics. 1 patient developed recurrent infection at the postoperative 3 months, and the overall 83% of controlled infection rate were showen in this series. The average follow up period was 1.7 years in these 6 patients, all patients are currently ambulatory. This results demonstrated the effectiveness of muscle flap coverage in chronic bony coverage of lower leg with large area of soft tissue defects. As a newly designed retrograde flow muscle flap. Reverse Extensor Digitorum Longus muscle flap trabsfer up 3 cases showed good results and it could be expected good method in moderate to large sezed defects of distal third & middle third of tibia, ankle. nkle.

이용자 수에 다른 혼잡분석 - 대구시 달성, 중앙공원을 대상으로-

도시공원의 혼잡에 관해 실제 이용자가 느끼는 혼잡정도와 이용밀도를 중심으로 조사한 결과 다 음과 같이 요약할 수 있다. 이용밀도는 계절과 요일에 따라 큰 차이가 있으며 외국에 비해 상당한 과밀이용을 나타내고 있었다. 이용밀도와 혼잡간에는 높은 상관성을 보이고 있으며 고밀도에서 이용자가 증가할 때 보다 저밀도에서 이용자가 추가될 때 혼잡도에 더 큰 영향을 미쳤다. 이용자가 증가 하여도 혼잡에는 크게 영향을 미치지 않는 혼잡포화점에서의 1인당 공원이용가능 면적이 약10$m^2$로서 우리민족의 밀집공간에 대한 강한 내성을 나타내었다. 앞으로는 본연구에서보다 다양하고 폭넓은 공원녹지를 대상으로 한 실증적 연구가 뒤따라야 할것으로 생각된다. This survey was carried to determine the crowd In the city parks on the basis of the crowding and using denSity. The using density was vary different by season and day, and the density was much higher in this experiment than in the case of the foreign countries. This survey shows a high correlation between the using density and crowd as the crowd level was more influenced by the increasing number of park - users in the case of low using density than the high using density. The possible using space per individual was around 10㎥ in the parks, which means a strong endurance of the surveying group to the massing space, in the saturated crowding value that the crowd was not significantly affected by the increasing number of users.

With the increase of traffic and traumatic accidents, parotid duct injury is increasing as facial injuries, and choice of treatment is immediate anatomical repair of transected parotid duct. Recently, microsurgical techniques are applied for the repair of transected parotid duct and accompnying buccal branchinjuries, and much improved results are expected. We present review of medical records of 12 patients with parotid dut injuries and our experiences of surgical management of these problems from January 1985 to April 1991. The results are summarized as follows: 1) Male was more frequently injured than female and the ratio was 3:1. 2) The most common cause of injury was traffi accident(58.3%), and followed by stabwound(25.0%) and fall down(16.7%). 3) The most prevalent transection site of parotid duct was over the masseter muscle(43%), and two cases(16.7%) were transected segmentally. 4) Buccal branches of facial nerve were transected in 75% of parotid duct injury cases. 5) Transected parotid ducts were repaired with 8-0 nylon sutures under the surgical microscope, and silastic or polyethylene stent was tubed for 2 weeks postoperatively. 6) With the follow up, operative results using microsurgical technique were excellent in all patients.

피부 악성 종양 절제 후 장장근건을 포함한 복합 요골 전완 유리 피판술을 이용한 중안면부의 재건

The reconstruction of the suborbital area followed by resection of skin cancer has been used many methods including skin graft, local flaps, free flaps, and skin expansion. The radial forearm free flap has become a workhorse flap in this area because of its lack of bulk, ease of dissection, malleability, and hairlessness. When the suborbital defect especially including full-thickness defect of lower lid was reconstructed with many free flaps, the ectropion and the deformity of medial and lateral canthal area were common problems encountered as late complication due to gravitational descent. To improve the final aesthetic result in patients with suborbital defect, the radial forearm free flap was elevated as a composite radial forearm - palmaris longus free flap, in which the vascularized palmaris longus london was included and anchored to the periorbital bone with $mitek^{(R)}$ as sling, to suspend the flap against gravity and inferior descent, and thereby creating a more natural cheek contour. Two clinical cases were presented as an example of this procedure. Postoperative results emphasize the importance of suspension sling with palmaris longus tendon using $mitek^{(R)}$ in reconstruction of the suborbital defect with radial forearm free flap.

大邱市 達性公園의 利用實態 調査

李鉉澤 경북대학교 1985 論文集 Vol.40 No.-

In order to obtain basic data for planning city parks, citizens' utilization of Dalsung park, the first park of Tague, was investigated. The results obtained are summarized as follow; Motive of visiting, activities in the park, and desired types of park were questioned to the Dalsung park visitors. Answers highly evaluated the forest and quiet rest space-indicating citizens' strong demand for nature. The majority of the users (79%) were visiting with friends or family suggesting that planning parks for group visitors would be necessary. Residents within a radius of 2 to 5 km around the downtown and 6 km around Dalsung park visited the park most frequently. About 80% of the visitors spent about 30 minutes to get to the park from home indicating that an inducement distance in time of Dalsung park would be 30 minutes. There was a large fluctuation in number of visitors by month and season. It suggests that park service should be improved to attract vistors all seasons. Many of the visitors over 50 years old were visiting the park everyday and those less than 50 were visiting the park once or twice a year. It means that many of the old visitors are everyday visitors.
