Purpose : Malformation of urinary tract is among the most common of all congenital anomalies and can progress to irreversible renal damage before diagnosis due to difficulty of early diagnosis. Present study was undertaken to determine the clinical characteristics of urinary tract anomaly and to find out the most appropriate diagnostic and therapeutic measures for children with these anomalies. Methods : During the past 10 years from 1987 to 1998, review of medical records revealed 65 children with congenital anomaly of urinary tract and the following results were obtained. Results : The most common anomalies were ureteropelvic junction obstruction occuring in 26 cases ($36\%$), followed by ureteral duplication in 11 cases, renal agenesis in 10 cases and ureterovesical function obstruction in 7 cases. Complex anomaly of urinary tract was found in 8 cases and anomaly of other systems such as congenital heart disease was detected in 11 cases. The most frequent age group at the time of diagnosis was below 1 year of age constituting 39 cases ($60\%$) and male preponderance was noted as male to female ratio being 2.25:1. Presenting symptoms were urinary tract infection in 25 cases, followed by hematuria, abdominal mass, abdominal pain and voiding difficulty, etc, and in 11 cases, the anomaly was picked up by routine prenatal ultrasonography. Azotemia was noted in 9 cases and the underlying anomaly was obstructive uropathy in 4 out of these 9 cases. Surgical correction was undertaken in 38 cases (most frequently in cases of obstructive uropathy) and in 2 out off cases with obstructive uropathy in whom surgical correction was done, azotemia disappeared during follow up period of 1-5years. No new cases of deteriorating renal function appeared during follow-up period. Conclusion : In spite of high incidence of congenital malformation of urinary tract, early diagnosis is still hampered by nonspecific symptoms and signs. Therefore, in patients with symptoms such as urinary tract infection, abdominal pain and voiding problems, etc, it Is advisable to take various diagnostic tests promptly to pick up any urinary tract anomaly and to apply proper therapy in order to avoid progression to irreversible renal damage. In this regard, prenatal ultrasonography should be utilized more widely as a routine procedure to detect any urinary tract anomalies before birth.

Background: Despite the excellent early results after the repair of congenital bicuspid aortic valve (BAV) disease, the mid-term durability of the repaired valve has still controversies. Material and Method: To evaluate the mid-term results of BAV repair, retrospective review of medical records and echocardiographic data were done. Between 1994 and 2003, twenty-two patients underwent reparative procedure for either regurgitant or stenotic congenital bicuspid aortic valve (BAV). Result: Mean age was $41\pm14$ years with male predominance (Male=17, Female=5). The pathophysiologies of the BAV were regurgitation-dominant in 20 (91%) and stenosis-dominant in 2 (9%) cases. Various repair techniques were used for raphe, prolapsed leaflet, thickened leaflet, and commissures; 1) release of raphe in 19 (86%), 2) wedge resection and primary repair in 11 (50%), pericardial patch reinforcement after plication of the leaflet in 6 (27%), and plication of the leaflet in 3 (14%), 3) slicing of thickened leaflet was used in 12 (55%) cases, 4) commissuroplasty in 8 (36%), and commissurotomy in 6 (27%) cases. There was no in-hospital mortality. During the mean follow-up of $38\pm17$ months, one patient underwent aortic valve replacement after developing acute severe regurgitation from dehiscence of the suture on postoperative 2 months. New York Heart Association functional class was improved from $1.9\pm0.6$ to $1.2\pm0.5$ (p<0.01). Left ventricular end-systolic and diastolic dimension (LVESD/LVEDD) were also improved from $45\pm9$ and $67\pm10$ to $37\pm10$ and $56\pm10,$ respectively (p<0.01). The grade of aortic regurgitation (AR) was improved from preoperative $(3.1\pm1.2)$ to post-bypass $(0.9\pm0.7).$ However, the grade at last follow-up $(1.7\pm1.1)$ was deteriorated during the follow-up period (p<0.01). Freedom from grade III and more AR at one, three, and four year were 89.7%, 89.7%, and 39.9% respectively. Conclusion: Midterm clinical result of the BAV repair was favorable. But, the durability of the repaired valve was not satisfactory.

Data mining is an information extraction activity to discover hidden facts contained in databases. Using a combination of machine learning, statistical analysis, modeling techniques and database technology, data mining finds patterns and subtle relationships in data and infers rules that allow the prediction of future results. Typical applications include market segmentation, customer profiling, fraud detection, evaluation of retail promotions, and credit risk analysis. Law enforcement agencies deal with mass data to investigate the crime and its amount is increasing due to the development of processing the data by using computer. Now new challenge to discover knowledge in that data is confronted to us. It can be applied in criminal investigation to find offenders by analysis of complex and relational data structures and free texts using their criminal records or statement texts. This study was aimed to evaluate possibile application of data mining and its limitation in practical criminal investigation. Clustering of the criminal cases will be possible in habitual crimes such as fraud and burglary when using data mining to identify the crime pattern. Neural network modelling, one of tools in data mining, can be applied to differentiating suspect's photograph or handwriting with that of convict or criminal profiling. A case study of in practical insurance fraud showed that data mining was useful in organized crimes such as gang, terrorism and money laundering. But the products of data mining in criminal investigation should be cautious for evaluating because data mining just offer a clue instead of conclusion. The legal regulation is needed to control the abuse of law enforcement agencies and to protect personal privacy or human rights.

Purpose : While pediatric observation units (POU) have become a common practice in hospitals throughout developed countries, there has been no report about POUs in Korea so far. The aims of this study were to analyze our one-year's experience of the POU and to decide which disease entities are suitable for the POU. Methods : All children admitted from March 2006 to February 2007 to the POU at the Department of Pediatrics in Our Lady of Mercy Hospital were included in this study. Data were collected from retrospective reviews of their medical records. Results : There were a total of 1,076 POU admissions. Median age of patients was 2.4 years and median length of hospital stay 14.0 hours. The most common diagnoses were gastroenteritis (42.7%), pharyngotonsillitis (19.1%), bronchiolitis (7.8%), pneumonia (5.5%) and febrile seizure (5.2%). Overall, 7.5% of the POU patients required subsequent inpatient admissions due to hospital stays of longer than 48 hours. The disease entities that were most likely to require inpatient admission were pneumonia (17.0%), febrile seizure (12.5%) and asthma (11.5%). Diseases that allowed successful discharge from the POU were gastroenteritis (4.6%), upper respiratory tract infection (5.8%), such as otitis media and pharygnotonsillitis and seizure disorder (6.4%). Compared with the previous year when the POU was not in operation, there was a statistically significant reduction in the average length of hospital stays (from 4.69 to 3.75 days), as well as a rise in the bed turnover rate (from 78.8 to 98.2 patients/bed). Conclusion : Our study shows that the POU is efficient for the management of children with certain acute illnesses. Based on this study, we suggest that the POU be used as a new modality which links between the outpatient, inpatient, and emergency departments in the field of pediatrics in Korea.

Methods : We retrospectively reviewed the medical records of patients with acute drug intoxication and foreign body ingestion from January 1991 to December 1994 and from January 2001 to December 2004. We performed clinical analysis and compared the results of the 1990s and 2000s. Results : There were 43 cases of acute drug intoxication in the 1990s, and 35 cases in the 2000s. Foreign body ingestion was 47 cases in the 1990s and 22 cases in the 2000s. The ingested foreign bodies were chiefly coins (46.8 percent), Weiqi chips (14.9 percent), plastic toys (6.4 percent) and others (31.9 percent) in the 1990s. In the 2000s, others (58.2 percent) were the most commonly ingested foreign body with mercury batteries (23.8 percent), nails (9 percent), pins (9 percent) following. The most common cause of drug intoxication was medical drugs (37.2 percent) others (23.2 percent), agricultural agents (13.9 percent), carbon monoxide (11.6 percent), rodenticide (9.3 percent), insecticide (9.3 percent) in the 1990s. In the 2000s the most common causes were others (34.3 percent), medical drug (31.4 percent), agriculture agents (20 percent), detergent (11.4 percent), insecticide (2.9 percent) and carbon monoxide (2.9 percent). The highest incidence age group was the 1-3 year old group, both in acute drug intoxication and foreign body ingestion. There were no changes in the incidence age group between the 1990s and the 2000s. Conclusion : There were some significant changes in the cause of acute drug intoxication and foreign body ingestion between the 1990s and 2000s. New education programs for preventing acute drug intoxication and foreign body ingestion are important and necessary.

The stone Buddha statue of Sangunsa Temple at Bukhansan in Goyang, Gyeonggi Province, is an excellent example of stone Buddha statues created in the late 15th century. On the base of the figure, there is an inscription, which informs that it was produced in 1497. In recognition of this significance, it was recently designated as a tangible cultural asset in Gyeonggi-do. Thus, this paper tried to evaluate the value of the statue by analyzing iconography and style. The characteristics of a typical 15th-century style that the Buddha statue of Sangunsa Temple shows are the form of ushnisha, the way clothes are worn, the form of a w-shaped chest muscle, and the simple lotus pedestal. On the other hand, the elongation of the waist and the disappearance of the waistband on undergarments are new forms of Buddha statues in the 16th century. Besides, parting the hair in the middle of the head and leaf-shaped short ribbon draped on undergarments are unique features that only appear on the statue of Sangunsa Temple. Sangunsa has been known to be built in the early 18th century based on Bukanji compiled by Seongneung in 1745, and Bongeunbonmalsaji composed in 1943. However, the statue was created in the late 15th century, before the establishment of the temple in the early 18th century. Therefore, this paper briefly reviewed the history of Sangunsa Temple, focusing on the initial period, referring to the historical sites and the relics that were passed on to the temple, as well as the literature records. The data newly referred to in the study are as follows: Sangunsa Stone Pagoda, presumed to be from the Goryeo Dynasty; the Stone Buddha Statue of Sangunsa; Wooden Amita Triad Buddha Statue of Sangunsa. According to the data and contrary to previously-held beliefs, Sangunsa Temple is believed to have been operating since the Goryeo Dynasty. It can be inferred through analysis of the stone Buddha statue of Sangunsa Temple that the size of the Temple before the 18th century was not very large.

Recently, U.S. Department of Transportation (DOT) expanded the "Enhancing Airline Passenger Protections" on August 23, 2011 and October 24, 2011. The Rule regulates tarmac delays, denied boarding compensation, customer service plans, and fare advertising. The adopted rule is to protect passengers by improving passenger service requirements on U.S. national or domestic carriers and foreign air carriers as well. The major issues are as follows: First, regarding to so called Tarmac Delay, carriers must establish a Tarmac Delay Contingency Plan setting forth the number of hours the carrier will permit an aircraft to remain on the tarmac at U.S. airports before allowing passengers to deplane. Carriers also must provide passengers with food and water in the event the aircraft remains on the tarmac for two or more hours and must provide operable lavatories and medical attention while the aircraft remains on the tarmac, irrespective of the length of the delay. Carriers also must create and retain records regarding tarmac delays lasting more than three hours. Also they need to update passengers every 30 minutes during a tarmac delay of the status of the flight and the reason for the delay, allow passengers to deplane if the aircraft is at the gate or another disembarkation area with the door open. Second, carriers now must adopt a "Customer Service Plan" that addresses offering customers the lowest fares available, notifying customers about delays, cancellations, and diversions; timely delivery of baggage; accommodating passengers' needs during tarmac delays and in "bumping cases"; and ensuring quality customer service. Third, the new regulations also increase minimum denied boarding compensation limits to $650 / $1,300 or 200% / 400% of the fare, whichever is less. Last, the DOT also has modified its policies related to enforcement of Rules pertaining to full fare advertising. The Rule states that the advertised price for air transportation must be the entire price to be paid by the customer. Similarly, Korea revised the passenger protection clauses within Aviation Act. However, it seems to be required to include various more issues such as Tarmac Delay, oversales of air tickets, involuntary denied boarding passengers, advertisements, etc.

Background : A clinical study was carried out on 153 new cases with small cell lung cancer registered at Presbyterian Medical Center, Chonju during the 7 years from 1986 to 1992. They were analyzed by sex and age distribution, symptoms and signs, classification of stage and site and its treatments. Especially, an effort was made to compare the overall survival time between limited stage and extensive stage. Methods : Among 806 lung cancer patients diagnosed by biopsy or cytologic evaluation for the 7 years, 153 patients was shown small cell lung cancer. These 153 cases was analyzed retrospectivery through patient's records, letters or telephones. Results : The results of evaluation of small cell lung cancer are as follows. Over 85 percent of the small cell lung cancer patients were over 50 years of age and prominent clinical features were cough(86.3%), sputum(75.8%) and dyspnea(54.9%). One hundred and five patients(68.7%) was staged to have limited stage. Mean survival time of the chemotherapy and chemoradiotherapy in limited stage has significant difference and its survivals are 5.3 months and 15.0 months. Patients whose disease was staged as limited, regardless of whether or not chemotherapy was administered, had a median survival time of 10.9 months, compared with 4.8 months for those with extensive stage. Conclusion : Lung cancer is one of the malignant diseases tend to increase gradually in Korea and proven to be the most common cancer next to the gastric cancer among various cancers in males found at the Presbyterian Medical Center in the past seven years. This report is a retrospective view of the clinical therapeutic results of the small cell lung cancer patients. Especially at the limited stage, the combined therapy revealed higher survival rate than the chemotherapy alone. For a more accurate evaluation. a prospective view, without any bias, of patients selected at random is needed.
