현재 인터넷상에서는 유아들을 위하여 온라인 상에서 학습을 할 수 있도록 하는 유아 학습 프로그램이 제공되어져 있는 사이트들을 많이 접할 수 있다. 그러나 여기에는 거의 모든 유아학습 사이트들이 유료화 되어있고 중심이 유아에게만 맞추어져 있다. 따라서 본 논문에서는 유료화를 없애고 부모들이 유아들을 양육하는데 있어서 꼭 필요한 유익한 정보를 제공하며, 부모가 함께 참여하여 학습할 수 있도록 하는 학습 시스템을 구현하였다. 이 시스템은 플래시를 이용한 무비파일로 이루어져 있어 이를 학습함으로써 유아들의 흥미와 학습하려는 의욕을 향상시킬 수 있다.

비만과 관련된 질환은 당뇨병, 고혈압, 고지혈증, 죽상경화증(동맥경화증), 심근경색증, 지방간, 담석증, 골 관절염, 통풍, 폐쇄성 수면 무호흡증, 대장암, 직장암, 전립선암, 유방암, 자궁내막암 등의 각종 암, 불안, 우울, 적응장애, 히스테리 등의 심리적 질환 등이 있다. 비만이 있을 때 우리 몸에서는 인슐린 자체에 대한 저항성이 생겨서 말초조직에서의 포도당 이용이 감소된다. 연구에 의하면 표준체중의 45$\%$ 이상을 초과한 비만환자는 당뇨병 발생의 위험도가 30배 증가된다고 알려져 있다. 비만이 있을 때 흔히 동반되는 질환들 중 특히 고혈압, 고지혈증, 죽상경화증 등의 질환은 당뇨가 있을 때 흔히 동반될 수 있는 질환들이고, 인슐린 저항성과 깊은 관계가 있는 질환들로 당뇨인들에게 비만은 매우 중요한 질환이라고 할 수 있겠다.

Carcinoma of the gallbladder is an uncommon but highly malignant tumor with a poor five year survival rate. Early detection is very important for successful treatment because this tumor is very hard to cure in cases where it has advanced beyond the reach of surgical treatment. The purpose of this review was to evaluate risk factors for carcinoma of the gallbladder and determine the best management approach.. Solitary polys, more than one cm are considered to be predisposing factors for gallbladder carcinoma when they are found to be echopenic, sessile, and with a high cell density. Anomalous union of the pacreato-biliary duct(AUPBD) without a choledochal cyst is also considered to increase risk for gallbladder carcinoma. A polyps size of more than one cm and an AUPBD are indications for prophylactic cholecystectomy. The presence of gallstones is a well-established risk factor for the development of gallbladder carcinoma; risk appears to correlate with the stone size and the duration of chronic cholecystitis. Metaplastic changes of the gallbladder epithelium present with chronic cholecystitis and may indicate a premalignant lesion. Abnormal forms of cholecystitis such as xanthogranulomatous or a porcelain gallbladder also have malignant potential; cholecystoenteric fistula as well as bacterial infection of the gallbladder(typhoid, helicobacter species) also has malignant potential. In this review, the risk factors associated with carcinoma of the gallbladder are summarized with special attention to gallstones, polyps, AUPBD, and chronic inflammation.

The concentration of free fatty acids and fatty acid composition as well as cholesterol supersaturation in bile may be an important factor in the gallstone formation. Therefore, we simultaneously determinded 23 fatty acids in bile by selected ion monitoring (SIM) method of gas chromatography-mass spectrometry (GC-MS). Biliary fatty acids were extracted by aminopropyl column and the extracts with (phospholipid fraction) or without (free fatty acid fraction) alkaline hydrolysis of phospholipid were derivatized with MSTFA/TMCS (N-methyl-N-trimethylsilyl-trifluoroacetamide/trimethylsilylchloride) mixture in order to be detected on the GC-MS. The recovery range of this method was 61.1-99.0% and the RSD value of within-a-day and day-to-day test were 3.1-25.6% and 3.8-27.0%, respectively. Using this method, biliary profile was investigated in the bile of normal controls and patients with gallstones. The amounts and their distribution of free and phospholipid fatty acids showed different pattern between normal subjects and patients.

This study aimed to understand the correlations of prevalence and relevant variables of cholelithiasis with a group of cirrhosis patients and a control group targeting the subjects who received the abdomen ultrasonography from K university hospital in Daejeon Metropolitan City from January 1^st 2019 to December 31^st. And the results are as follows. First, the group of cirrhosis patients showed relatively higher prevalence of cholelithiasis than the control group as ordinary people, which showed statistically significant differences. Second, in the control group, there were statistically significant differences in the occurrence of cholelithiasis with respect to age. Conversely, in the cirrhosis patient, there was no statistically significant association observed with age; nonetheless, age itself exhibited statistical significance. Third, according to sex, the prevalence was not statistically significant in both group of cirrhosis patients and control group. Fourth, in each degree and cause of subdivided cirrhosis, the correlation was only shown in each degree. In the results of this study, the cirrhosis patients showed high correlation with the incidence of cholelithiasis, and the control group showed the high correlation with the incidence of cholelithiasis according to age.

Cholelithiasis and choledolithiasis were diagnosed with serum chemistry, abdominal radiography and ultrasonography in a 2.0 kg, 10 year-old Yorkshire Terrier dog showing signs of anorexia, vomiting, iceterus and depression. In serum chemistry, the level of alanine transferase, alkaline phosphatase, aspartate transferase, total bilitrubin and direct bilirubin were elevated. On abdominal radiographs, focal lesions with increased radiopacity were seen in the hepatic region and the size of liver was increased. In ultrasonographic examination, it were seen that distension of gall bladder, hypercehoic change of liver, obstruction of cystic duct by calcult and calculi in the gall bladder. Cholecystectomy was undertaken and there were no complications after the operation.

Objective : This study was designed to investigate the effects of herbal medicine on jaundice caused by hepatic resection. Methods : This study was carried out on one patient with jaundice ensued by hepatic resection. The patient was admitted on October 25th, and treated until November 13th, 2004, using acupuncture and herbal medicine(Hepacure-I and Ex.Sosiho-tang.) Result : After 18 days, clinical symptoms had improved. Results of total bilirubin, ALP, GGT tests and urinalysis also showed improvement. Conclusions : These result support a role for this combination of acupunture and herbal medicine in treatment of chronic liver disease.

A 6-year-old, intact female mixed dog was referred to Veterinary Medical Teaching Hospital of Gyeongsang National University due to vomiting, anorexia, depression of 1 month's duration. On abdominal radiography, numerous irregularly marginated mineralized branching structures were present within the liver. On ultrasonography, irregular hyperechoic spots with an strong acoustic shadow was identified, but evidence of ductal dilatation was absent. Based on radiography and ultrasonography, intrahepatic gallstones were diagnosed incidentally.

A twelve-month old female, shih-tzu, was presented to diagnose a hind limb ataxia to the Animal Teaching Hospital, Gyeongsang National University. Even though a variety of physical and neurological examination was performed, the cause of the ataxia was not understood. In serum analysis, an elevated levels of ALT, $\gamma$-GTP and LDH were found. A gallstone was subsequently observed at the right 9 and 10th intercostal region on ultrasonography and radiography. Cholelithiasis was diagnosed, and then cholecystotomy was undertaken. No complications were occurred after the operation. The gallstone removed by cholecystotomy was composed of calcium, carbonate and oxalate, identified by a black pigment gallstone.
