Objective : The aim of this study was to describe a single center's experience in the management of craniopharyngiomas in children over a 15-year period. Methods : The clinical records of pediatric patients treated for craniopharyngiomas between December 1995 and February 2011 were reviewed. Thirty-five pediatric patients diagnosed with craniopharyngioma were treated, and their medical records and imaging data were analyzed retrospectively. Results : The mean follow-up duration was 76 months (range, 10-195). Overall survival and local control rates at 10 years were $94.7{\pm}5.1%$ and $37.1{\pm}11.9%$, respectively. The female-to-male ratio was 16 : 19, and the mean age was 8.6 years (range, 1-17). Initially, gross total resection (GTR) was performed in 30 patients; subtotal resection (STR) followed by radiotherapy was performed in 5 patients. Of the 14 cases that showed recurrence after GTR, 5 patients were treated with GTR, 1 with radiation therapy (RT), 4 with gamma knife radiosurgery (GKRS), and 4 with subtotal resection followed by RT. No patients who underwent RT or GKRS had recurrences. Two cases with recurrence after STR followed by RT were treated with GTR. One patient died of hormonal insufficiency 64 months after the first surgery. The overall median time progression was 51.2 months (range, 3-182) : 49.7 months in the patients who underwent GTR and 60.2 months in the patients who underwent STR followed by RT. Conclusion : If safe resection is possible, GTR at the initial treatment should be attempted to reduce the tumor recurrence. However, if the tumor recurs after the first surgery, RT or GKRS with/without reoperation may be an effective salvage treatment for recurrent craniopharyngioma.

The purpose of this study is to evaluate the demographic characteristics, alcohol-related characteristics and personality trends in the participants of Alcoholics Anonymous. We compared the 33 participants of Alcoholics Anonymous maintaining abstinence at least over 6 months with 35 hospitalized alcoholic patients who have never attended Alcoholics Anonymous and 32 normal controls. The personality trend was measured by Catell's 16 Personality Factors Questionnaire. -Korean Version. The results were as follows: 1) In the demographic data, the participants of Alcoholics Anonymous were mainly 40's, graduated from high school, married, unemployed, middle class in economic state, first or second sons. 2) In alcohol related characteristics, age of first drinking was mainly distributed from 15 to 19 years-old. The most common psychosocial and environmental problem as precipitating factor of alcohol consumption was the problem with primary supper group and the second one was occupational. Most of them drank everyday, and admitted one time. 3) In the first stratum sources traits, the participants of Alcoholics Anonymous demonstrated significantly higher score than hospitalized alcoholic Patients, but lower than normal control in C-factor(stableness). They demonstrated significantly higher score than hospitalized alcoholic patients and normal controls in O-factor(Guilt-proness) and demonstrated significantly higher score than hospitalized alcoholic patients in Q3-factor(self-control). 4) In the second stratum sources traits, they demonstrated significantly higher score than hospitalized alcoholic patients in EXT-factor(extroversions), and lower score than hospitalized alcoholic patients and normal controls in IND-factor(independence).

This paper focuses on listening test and acoustic analysis of patients' speech with velopharyngeal insufficiency (VPI) and normal speakers' simulation speech. In this research, a set consisting of 50-words, vowels and single syllables is determined for speech database construction. A web-based listening evaluation system is developed for a convenient/automated evaluation procedure. The analysis results show the trend of incorrect recognition for VPI speech and the one for simulation speech are similar. Such similarity is also confirmed by comparing the formant locations of vowel and spectrum of consonant sounds. These results show that the simulation method for VPI speech is effective at generating the speech signals similar to actual VPI patient's speech. It is expected that the simulation speech data can be effectively employed for our future work such as acoustic model adaptation.

Cardiovascular magnetic resonance imaging (CMR) is expected to be increasingly used in Korea due to technology advances and the expanded national insurance coverage of these tests. For improved patient care, it is crucial not only that CMR images are properly acquired but that they are accurately interpreted by well-trained personnel. In response to the increased demand for CMR, the Korean Society of Cardiovascular Imaging (KOSCI) has issued interpretation guidelines in conjunction with the Korean Society of Radiology (KSR). KOSCI has also created a formal Committee on CMR Guidelines to write updated practices. The members of this Committee review previously published interpretation guidelines and discuss the patterns of CMR use in Korea.

Uterine myomas are heterogeneous tumors in composition, size, location, and number; variation in any of these factors could possibly alter the effect on a woman's fertility status. The effect of myomas on fertility has been the subject of many studies. However, a definitive answer is still missing. The location and size of the myomas are the two parameters that influence the success of a future pregnancy. Subserosal myomas seem to have little effect on reproductive outcome. Myomas that compress the uterine cavity with an intramural portion and submucosal myomas significantly reduce pregnancy rates, and should be removed before assisted reproductive techniques are performed. Patients with intramural myomas also may have a poorer reproductive outcome, but the lacks of quality evaluations make this conclusion tenuous at best. Removal of myomas with an intra-cavitary component seems to be of benefit. However there are as yet no data to support myomectomy in the treatment of intramural myomas to improve fertility outcomes. Treatment modality for myomas located at intramural sites should be determined according to clinical status of the patient and doctor's experience.

The purpose of the study was to analysis physician's prescribing behavior. Data was collected from 320 medical doctors of 10 general hospitals from August to September in 1996. The major findings are as follows; 1) Prescribing dosage: 74% of total selected middle dosage. Resident doctors used maximum dosage. 2) The number of similar antibiotics: 72.4% of total used 1 antibiotic. Surgery depts. and resident doctors selected 2, 3 antibiotics. Physicians to consider of insurance benefit or non insurance benefit used the number of antibiotics less than not to consider. Physicians to think over patient's economic state used less the number of antibiotics than that not to consider. 3) Used term of antibiotics: Total mean was 7.39 days. medical parts had 9.11 days but surgery used 6.41 days. Specialists consumed 6.57 days and residents applied 7.80 days. Physician to reflect result of claim used short term of antibiotics than that don't reflected. 4) Optional order of antibiotics: First antibiotics were selected 68% of total respondents, by medical depts, but secondary, tertiary antibiotics was used surgery depts. Tertiary antibiotics was used residents doctors, universal hospitals, fill beds and over. 5) The number of the items of oral drug : 3-4 the items of oral drug were used 76% of respondent Surgery parts selected 1-2 the items of oral drug, medical depts. selected five and over. Physician to reflect result of claim used less the number of the items of oral drug than that don't reflected. Physician to prescribe different of class of insurance used less the number of the items of oral drug than that don't prescribe different.

The purposes of this study were to determine correlations between the Berg Balance Test (BBS), Timed -UP & Go Test, Fugl Meyer-L/E, Balance, Sensory (FM-L/E, B, S), Motor Assessment Scale-Gait (MAS-G), Comfortable maximal Gait Speed (C MGS), and the Modified Barthel Index (MBI). The subjects were 40 stroke patients of the Korea National Rehabilitation Center in Seoul. Main outcome measures were Balance control (BBS, FM-B), Gait (TUG, C MGS, MAS-G), ADL (MBI) and Motor Function of Lower Extremities (FM-L/E, S). The data were analyzed using Pearson product correlation. FM scales between other clinical and instrumental indexes and multiple stepwise regression analyses were performed to identify prognostic factors for Balance, Gait and ADL Motor Function of Lower Extremity inclinations. The results of this study were as follows: The BBS, FM-L/E, balance, sensory and MBI showed positive correlation relations, but TUG and C MGS showed negative correlations. The sensory factor of the FM-scale showed the strongest variance in predicting BBS. However the FM-balance showed the strongest variance in predicting TUG, MAS-G and C MGS. The use of both quantitative and qualitative scales was shown to be a good measuring instrument for the classification of the general clinical performance of the patients.

Objective: The purpose of this study was to evaluate the patterns of Over-the-Counter (OTC) drugs and their interactions with prescription drugs in adults visiting a community pharmacy. Method: The subjects were 151 adults aged over 20 years visiting a community pharmacy in Asan-si from December 16th 2011 to February 1st 2012. We used a survey questionnaire. The survey inquired about the prevalence and the details of any OTC drug use and the characteristics of the study subjects. The drug interaction classification system from Lexicomp's Lexi-interact data fields was used to identify OTC drugs likely to have clinically significant interactions with prescription drugs. Results: The patterns of OTC drug use were related to thirties (from 30 to 40 years old), female gender, higher education, non-smoking, sometimes use of alcohol, and self-perceived normal health status. The most commonly used OTC drug category was antipyretic-analgesics (n=104, 53.3%), and the most commonly used ingredient was acetaminophen (n=67, 64.4%). The biggest motivation for taking OTC drugs was suggestion by pharmacists, reported by 55.6%. After reviewing each patient's prescription drugs and OTC drugs, 14 patients (36.8%) of 38 patients using prescription drugs were taking drug combinations with potential for clinically significant interactions. The concomitant use of OTC drugs with prescription drugs may lead to increased potentially harmful interactions. Conclusion: It is suggested that health-care professionals should be more aware of the potential and possible interactions and take into better account their patients' OTC drug use.

Ease of manipulation, adequate mechanical properties, long years of experience and economical cost are the factors which have established amalgam as the most widely used material for dental restorations. But amalgam restoration may require replacement because of secondary caries, fracture, "fall-out", dimensional change, tarnish or corrosion etc.. These failures of amalgam restorations seem to arise from failures during operations rather than from the inherent shortcomings of the material itself or of the patient's mismanagement. It is anticipated that notonly number of analgam restoration, but failures will be increase after more extensive utilization of the medical insurance which began in 1977. Then authors think that it would be helpful for the development of better treatment in daily dental practice, to know the duration of amalgam restorations and the reasons for their replacement. The data for this survey was compiled from 2, 856 out-patients of the Department of Dentistry, Ewha Woman's University Hospital from January 1975 to December 1977. 260 cases among 1,718 fillings were studied, of which 205 cases both had a single reason for replacement and recognized the date of the previous filling. The results obtained were as follows; 1. Amalgam fillings were 58. 5 percent of all dental restorative materials. Of these, 15. 13 percent of the amalgam restorations had to be replaced. 2. The first reason for replacement of amalgam restorations was secondary caries (56.10%), the second was fracture (23.80%) and the third was "fall-out" (8.78%). 3. Among those amalgms requiring replacement, 52.2 percent had been in place less than 3 years, 70.7 percent within 5 years and 89.8 percent had been in place less than 10 years. Only 10.2 percent had been in place more than 10 years.
