This study intended to examine the changes of residential building characteristics in period classification. The results of this study are as follows: During Joseon dynasty, it is judged that the social changes in the ideology of ruling classes did not directly affect the traditional residential style. The mid period and latter period of Joseon, it is changed toward horizontal and practical residential layout in place of confucian courtesy based style. During port opening period, the traditional residential style was remodeled through addition of glass panes to inter-chamber floor in tune with the influx of modern materials and ideologies like glass or cement etc. The Japanese ruling era of Korea period, the modern housing style of room separation type was settled.
느타리버섯 세균성갈빈병균 Pseudomonas tolaasii의 효소면역검출법

느타리버섯의 세균성갈반병균인 P. talaasii(PT)를 신속 간편하게 검출할 수 있는 효소면역측정법(ELISA)을 개발하였다. 특이항체를 생산하기 위하여 PT(5×10 exp (7) cfu)를 Freund's adjuvant와 함께 토끼에 수차례 면역하였으며, 가장 높은 역가를 나타낸 항혈청을 이용하여 비경합 ELISA 및 경합 ELISA를 각각 확립하였다. 표준곡선으로부터 PT의 그 검출한계는 각각 2×10 exp (2) cfu/ml 및 3×10 exp (2) cfu/ml가량으로 나타났다. 교차반응은 비경합 ELISA의 경우 P. agarici, P. reactans 및 비병원성 Pseudomonas속 균주와 1/10^3이하의 매우 미약한 반응을 보였으나 P. salanacearum, Erwinia chrysanthemi, Streptococcus mutans, Xanthomonas citri 및 곰팡이인 Fusarium oxysporum 등 다른 균주와의 반응성이 거의 없었으며, 경합 ELISA의 경우 PT이외에는 같은 속 균주에 대하여도 반응성이 거의 없었다. ELISA를 이용하여 버섯으로부터 분리된 18균주에 대하여 PT의 여부를 조사하였을 때 병원성과 white line 반응성을 동시에 나타내었던 11균주에 대하여만 명확한 양성으로 나타나, 본 연구에서 확립한 ELISA는 간편하고 정확한 PT검출법임이 확인되었다. For simple and rapid detection of Pseudomonas tolaasii (PT), a bacterial brown blotch pathogen of oyster mushroom, enzyme-linked immunosorbent assays (ELISA) were developed. To produce specific antibody, PT (5 × 10 exp (7) cfu) and Freund's adjuvant were subcutaneously immunized into rabbits several times. By using the antiserum showing the highest titer, we established noncompetitive and competitive ELISA's. Standard curves of the ELISA's showed that the detection limits were 2 × 10 exp (2) cfu/ml and 3 × 10 exp (2) cfu/ml, respectively. When investigated by noncompetitive ELISA, cross reactivities of the anti-PT antibodies against P. agarici, P. reactans, and other fluorescent Pseudomonas spp. were very low (<1/10^3), but those against P. solanacearum, Erwinia chrysanthemi, Streptococcus mutans, Xanthomonas citri, and a fungus Fusarium oxysporum were almost none. However, when investigated by competitive ELISA, the reactivities against any other strains except PT were almost none. When the ELISA's were applied to 18 strains derived from mushrooms in order to identify PT, only 11 strains showing both pathogenicity and white line reactivity were obviously positive. These results showed that the ELISA's could be convenient tools to detect PT in accordance with existing methods.

Diabetic foot infection is one of the important complications in patients with advanced diabetes mellitus. Limb threatening infections such as osteomyelitis, abscess, and necrotizing fasciitis are frequently accompanied by the disease. Non-tuberculous mycobacterium (NTM) is a rare causative organism of diabetic foot infection. Thus, if one is not suspicious or meticulous, infection due to NTM will be easily overlooked and this will result in delayed diagnose and treat. Therefore, it is necessary to consider NTM as the causative organism if the wound does not respond to the conventional antibiotic treatment and the culture from the adequately obtained specimen reveals atypical acid-fast bacilli. We present a case of diabetic foot infection with osteomyelitis and abscess due to Mycobacterium mageritense, one of the rapid growing mycobacteria, that was successfully treated with surgical debridement and appropriate antibiotic treatment.

Infectious diseases imported from other countries have increased as more and more Koreans are going abroad for various purposes. Tsutsugamushi disease from other endemic area such as Southeast Asia is important, because it can occur in any season and eschar may be absent. We report a case of imported tsutsugamushi disease acquired in the Philippines. A patient presented with fever, headache, and maculopapular skin rash. However, eschar was absent. Polymerase chain reaction (PCR) for 56-kDa gene of Orientia tsutsugamushi using buffy coat was positive. Serum indirect immunofluorescent antibody assay was initially negative but became positive with a titer of 1:320 at follow-up, Sequencing analysis revealed the strain to be 100% identical to the TW73R strain identified in Taiwan. After the patient received doxycycline, body temperature normalized in 12 hours. Tsutsugamushi disease is one of the differential diagnoses that should be included for patients with fever who have recently returned from Southeast Asian countries. PCR for O. tsutsugamushi using patient's buffy coat was useful for early diagnosis.

Plasmodium vivax malaria is an endemic disease in Korea, which rarely causes severe complications including those occurring in the cerebrum. There are limited numbers of complicated cases that have been reported around the world. We experienced a case of vivax malaria with cerebral complication: cognitive impairment and ataxia. A 55-year-old female with diabetes mellitus presented to the emergency department with acute fever of two days’ duration. She did not have any history of travelling abroad or receiving blood transfusions. Peripheral blood smear revealed vivax malaria with parasitemia density of 0.53 percent. She demonstrated loss of orientation, especially regarding time and place, and ataxia. Although the initial hydroxychloroquine treatment for malaria was successful, cognitive impairment and ataxia persisted and were not recovered. Brain MRI showed no structural abnormality. Brain PET showed diffuse hypometabolism in right parieto-temporal lobe of the brain.

Basal stem rot symptoms were found on blueberry seedlings imported from the United States of America in 2008. The fungus obtained from the diseased seedlings was identified as Calonectria colhounii based on morphological and molecular characteristics. The consignments of the blueberry seedlings infected with C. colhounii were destroyed to prevent introduction of the fungus to Korea.
