慶尙北道내 肺吸蟲 浸潤地 溪谷에서의 가재의 最近 棲息狀과 가재에서의 폐흡충 피낭유충의 最近 寄生狀을 究明코저 1981年 10月부터 1982年 9月까지 6個處(達城郡 嘉昌面 蛇洞, 玉盆洞, 上院洞과 榮豊郡 豊基邑 錦溪, 英陽郡 英陽面 化川 및 靑松郡 府東面 上宣溪谷)를 調査對象溪谷으로 選定하여 調査한 後 1974年 朴 및 崔의 調査 成績과 比較하였다. 6個處의 肺吸蟲 浸潤地에서의 가재의 棲息密度는 1974年의 그 密度에 比하여 顯著히 低下되었으며 가재에서의 폐흡충 피낭유충의 寄生率과 그 寄生程度도 1974年의 成績에 比하여 낮았다. 가재의 體部位別 폐흡충 피낭유충의 寄生狀에 있어서는 1974年에는 가재의 全體部位에서 本피낭유충을 찾아 볼 수 있었는데 比하여 이번 調査에서는 가재의 頭胸部, 아가미 및 肝에서만 찾아볼 수 있었으며 가재 한마리當 폐흡충 피낭유충數도 全浸潤地에서 1974年에 比하여 1982年에는 甚히 적었다. 폐흡충 피낭유충이 寄生하는 가재의 數와 이들 가재에서의 本피낭유충의 數가 1982年에는 너무 적으므로 가재의 크기와 本피낭유충數 및 1974年의 調査成績과의 相關을 求할 수 없었다. 이번 調査 結果 1974年에서 1982年까지의 지난 8年間 폐흡충 浸潤地에서 가재의 棲息密度와 폐흡충 피낭유충이 寄生하는 가재의 數가 急激히 減少되었음을 알았다. In an attempt to determine the recent patterns of population density of the crayfish, Cambaroides similis, and infestation of the crayfish with the metacercaria of Paragonimus westermani in Kyungpook Province, Korea, the crayfish collected in the six endemic areas, Kum-ge, Wha-cheon, Sang-seon, Ju-dong, Ok-bun dong, and Sang-weon dong streams were examined from April, 1981 to September, 1982. The results obtained in 1982 were compared with the data derived from the crayfish collected at the same streams by Park and Choi(1974). The population density of crayfish in the six endemic areas of P. westermani in the present study decreased markedly compared with those in 1974. The infestation rate for the metacercaria of P. westermani in the crayfish examined and the intensity of infestation in the positive crayfish also decreased compared with those reported by Park and Choi(1974). In the 1974 survey, the metacercaria was found in all parts of the crayfish whereas it was found only in the cephalothorax, the gills, and the liver in the present suevey. In the average number of metacercariae perpositive crayfish (M.P.P.C), a pronounced reduction was encountered in all endemic areas between 1974 and 1982. The number of infested crayfish and the metacercaria of P. westermani in infested crayfish in 1982 was so small that it was impossible to analyze the relationship between the number of metacercaria and the length of crayfish and to compare the data between 1974 and 1982. It was found in the present study that the population density of crayfish in the endemic areas and the infestation of the crayfish with the metacercaria of P. westermani has decreased drastically over the eight-year period from 1974 to 1982.

The photodegradation efficiency of chlorine oxides in the drinking water has been studied by means of laser flash photolysis. The results are summarized as follows ; A high amount of ClO is produced just at the irradiation of laser flash. The absorption spectrum of ClO shows strong on the spectrophotometric measurement. The efficiency of removal of ClxOy reveals about 60~70% within 2㎲ after laser flash irradiation. The removal efficiency is decreased with the increase of the water thickness from 40㎝ to 80㎝ and also the efficiency is decreased about 4~6%. The removal rate of Cl₂O_(7) shows 3 times higher than one of Cl₂O_(6).

The failure of expansion joint for bridge generally occurrs in the non-shrinking mortar while other problem is the release of anchors in expansion joint due to the impact and vibration by traffic on the bridge. In this study, to overcome the failure of expansion joint by the failure of mortar, the elastic mortar is developed. The pull-out capacity of developed elastic mortar was compared with that of non-shrinking mortar. Moreover the anchor system which can be changed easily and prevent a fracture of expansion joint is developed 교량 신축이음장치의 파손 유형은 주로 후타재(무수축 모르타르)와 관련된 부분에서 많이 발생된다. 또 다른 문제는 중차량 통과에 따른 충격과 진동하중으로 인해서 신축이음장치를 후타재에 고정하기 위해서 사용하는 앵커 풀림 현상이다. 본 연구에서는 무수축 모르타르의 파괴에 따른 신축이음장치의 파손을 방지하기 위해 탄성콘크리트를 개발하였다. 개발된 탄성콘크리트와 현재 주로 사용하고 있는 무수축 모르타르의 인발성능을 비교하였다. 또한, 후타재와 신축이음장치를 일체화하여 후타재의 파손을 방지하고 신축이음장치를 쉽게 교체할 수 있는 앵커 시스템을 개발하였다

Background: Onychomycosis is one of the most common nail disease around the world. No specific treatment other than drug therapy and surgery was suggested till present. Systemic antifungal drugs for onychomysosis are effective. However, they require a long treatment time and not suitable for people with other systemic disease. Furthermore, they may cause many side effects such as liver disease. Also, many patients prefer topical drugs or physical treatment. Objectives: The objective of this study was to evaluate the efficacy of combination treatment with a 1064 Nd:YAG laser and efinaconazole 10% Topical Solution. Methods: Ten patients with onychomycosis were treated with 1064 Nd:YAG laser (PinPointe FootLaser, Cynosure, Westford, MA, USA) once a month with application of 10% eifnaconazole solution(Jublia, Dong-A EST) once a day. The effectiveness of treatment were evaluated with before and after photographs. Results: Improvement were shown in 90% of patients after the treatment. However, 10% of patients had no response. Conclusion: This clinical study suggests that combination treatment of a 1064 Nd:YAG laser and efinaconazole 10% Topical Solutionis an effective, safe, and convenient treatment method for onychomycosis.
