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.

Chloral hydrate is one of the most widely used sedative agents to control the difficult-to-treat young age group in the dental clinic. The mormal onset time of oral Chloral hydrate is 30-45 minute with some variations. We are often frustrated see the patient still awake and cry with agitation even sfter far more than the normal onset time. In such a case, the pstient has to be rescheduled for another sedation visit with different agents and/or routes which greatly disappoints the guardians. This case report presents a sedative regimen that can possibly hilp the clinician complete scheduled treatment without postponement. We have tried additional administration of Midazolam intranasally to 22 patients of those who failed to respond properly to the initial dose(50-75mg/kg) of oral Chloral hydrate. The average age and weight of the patients was 34.2 months(22-61 mos.) and 15.2 kg(10-17kg) respectively. Half of the regular dose of Midazolam(0.1mg/kg) was administered intranasally using needless syringe in 42 cases without notable resistance of the patient. The onset was very rapid in most cases and could proceed the treatment under the constant monitoring by Pulse oximeter. All the planned procedures could be completed in 93.2%(69.4% of 'Good' plus 23.8% of 'Fair' rating)with only 6.8%('Poor' rating) of failure rate. Evidence of adverse effect was not detected or reported during and/or after the procedures.

The Purpose of this study was to empirically examine the relationships of flow experience, self-efficacy and performance level on activity level of boxing players. From the analysis of this study, the following conclusions were obtained : 1. There was a partial difference in boxing player's activity level, flow experience and self-efficacy by socio-demographic variables. First, in the activity level of boxing player, there was a difference both family income and performance level. The majority in the exercise career, the period of middle school boxing player was less than 2 years, high school boxing player less than 4 years and university boxing player less than 8 years. In the flow experience, cognitive flow experience did show the difference in the exercise career. The more exercise career, the lower cognitive flow experience was perceived. As the school record gets higher, the self-efficacy was increased and the performance level was higher in the ordinary group by school record. 2. There was a partial difference in the flow experience according to the activity level of boxing player. That is say, middle school boxing player was higher the perceived level for cognitive flow experience than the others, university boxing player was lower. But the behavioral flow experience according to the activity level of boxing player, did not show the difference. 3. The flow experience of boxing player had a partial influence on the self-efficacy. The cognitive flow experience of boxing player affected positively on the self-efficacy, while behavioral flow experience did not have any influence on the self-efficacy. 4. The flow experience of boxing player had a partial influence on the performance level. That is to say, the cognitive flow experience of boxing player affected positively on the performance level. 5. The self-efficacy of boxing player affected positively on the performance level. 6. There was a partial casual relation in the flow experience, self-efficacy, performance level of boxing player. The cognitive flow experience of boxing player affected positively on the performance level by the self-efficacy, cognitive flow experience and self-efficacy affected positively, directly on the performance level. But the behavioral flow experience did not have any influence directly or indirectly on the self-efficacy and performance level.
