We considered the problem for confirmation of multiple outliers and leverage points. Identification of multiple outliers and leverage points is difficult because of the masking effect and swamping effect. Jong-Young YOO and Kisoo-Ahn(2002) identified multiple outliers and leverage points by using the adjacent effects which are high-breakdown robust estimators. In this thesis, We proved the efficiency of Jong-Young YOO and Kisoo-Ahn's method by comparing with five procedure(Sequential testing of maximum internally studentized residual, Sequential testing of maximum externally studentized residual, Marasinghe's multistage procedure and two procedure based on recursive residuals).

Background: Micafungin, a potent inhibitor of 1,3-β-D-glucan synthase, is a novel antifungal agent of the echinocandin class. In vitro study showed that micafungin was effective against Aspergillus species as well as Candida species, but clinical data on the prophylactic efficacy against invasive fungal infections (IFIs) other than candidiasis are still lacking. Materials and Methods: We identified 60 consecutive adult hematopoietic stem cell transplantation (HSCT) recipients who received at least 3 doses of micafungin during neutropenic period. Micafungin was started as an alternative in patients who were intolerant or had adverse events (AEs) to primary prophylactic antifungal agents. We retrospectively reviewed the medical records and analyzed the efficacy and safety of micafungin for prophylaxis against IFIs. Results: The patients either had autologous (n=9) or allogeneic (n=51: 1 syngeneic, 24 sibling, 26 unrelated donor) HSCT. Itraconazole oral solution (n=58) was the most frequently used first line antifungal agent for prophylaxis and was administered for median 11 days. The most frequent cause of switch to micafungin was vomiting (n=42). The duration of neutropenia and micafungin administration was median 13 and 12 days, respectively. A successful outcome was achieved in 45 (75%) patients. Empirical antifungal therapy was initiated in 13 (22%) patients. There were 2 cases (3.3%) of breakthrough fungal infections which comprised a probable invasive pulmonary aspergillosis and a possible invasive fungal sinusitis. There was no case of invasive candidiasis. A total of 53 (88%) patients experienced at least one AE regardless of causality during micafungin administration. The most frequent AEs were hypokalemia, vomiting, diarrhea, and elevated serum aspartate aminotransferase or alanine aminotransferase. Among the aforementioned AEs, only 1 case of diarrhea could be classified as a probable relation with micafungin when causality was assessed. There was no AEs that caused discontinuation of micafungin. Conclusions: Micafungin seems to be a safe and effective agent for prophylaxis of IFIs including aspergillosis as well as candidiasis in HSCT recipients. However, further large, prospective, and randomized comparative studies are warranted for aspergillosis.

백색부후균 Trametes versicolor(CV5) 균주에 의한 wood lignin의 분해능을 조사하였다. CV5는 활엽수와 침엽수에 속하는 여러 수종의 프로토 리그닌 분해 시 활엽수에 한해서 분해되는 특성을 보였으며, 특히 상수리나무에서 33.5%의 가장 높은 리그닌이 분해되었다. 리그닌 분해에 관련된 phenoloxidase 분비능을 Bavendamm 시험을 통해 검토한 결과 CV5는 지금까지 연구된 우수 백색 부후균과 같은 유사 반응 형태를 나타내고 있음을 확인하였다. 또한 상수리 목재 chip표면에 CV5의 균사가 생육하면서 목재조직이 부후된 상태를 주사전자 현미경으로 관찰한 결과 목섬유 및 도관에서 균사의 침투와 목재조직의 분해를 확인하고 리그닌에 대한 높은 선택적 분해력을 갖고 있음을 구명하였다. Trametes versicolor(CV5) selected as a white-rot fungus with strong lignin degrading activity, in the previous paper, was investigated on a properties of degradation of wood lignin. Lignins of hardwoods, especially oak(Querous acutissima carruth) an paulownia (Paulownia coreana Uyeki) were considerably delignified by the CV5, however, softwoods used in this experiment were not delignified. Bavendamm's reaction was positive with several phenols on agar plates for the confirmation of a phenoloxidase secreted Through the morphologies of decayed wood chip observed with the aid of scanning electron microscopy, it was found that the hypha of CV5 penetrated the ray cells and vessels caused separation of the wood cellulose.

According to the classification of climate by Ko^‥ppen and McCune, the Korean peninsula belongs to the C (temperate) and D(polar) climatic divisions. This division is further divided into a local climatic area, thus the climate of the southwest inland area, seacoast and islands belong to CSW and CS climatic types. The climate of the northwest monsoon area which is affected bf the oceanic and the chinese continent climatic type is classified by the distribution of land and sea. For this study, two sites in the CSW and CS areas and the boundary area between the CSW and CS areas were selected, and the distribution of climatic elements were examined according to such weather data of the last ten year (1972 to 1981) as air temperature, amounts of precipitation and evaporation, relative humidity, duration of sunshine, wind speed and fog days. The air temperature showed a wide annua1 range in the order of Jeonju, Gwangju, Goheung, Mogpo, Yeosu and Wando, so the temperature was identical with the theoretical numbers. The precipitation was conspicuously high on island, showing a temperate type precipitation and large annual variation. It is a peculiar phenomenon that the coastal areas had the least annual mean precipitation. The humidity of Inlands, seacoast, and islands areas was similar to one another. The humidity in summer showed a high measurement, thus Indicating that the theoretical numbers were different from the actual measurements. The duration of sunshine in the selected sites was longest in May and August and shortest in June and July. and the duration on islands was longer than that of inlands. The amount of evaporation was similar to the duration of sunshine, so the amount was high in May and August, and low in December and January. The small amount of evaporation in June is connected with the duration of sunshine. It is a peculiar phenomenen that the amount of evaporation in Gwangju area was higher than that of the other areas. The wind speed in winter was higher than in summer, and the seacoast area's wind speed was particularly high. The fog days were very frequent in June and July in the coastal areas of Yeosu, Mogpo and Wando, and the other areas showed similar fog days all the year round. Especially, Yeosu showed conspicuously frequent annual mean fog days compared with the other areas.
