Purpose : Infantile colic is one of the most commonly encountered problems, characterized by excessive crying in apparently healthy young infants within the first 3 months of life. It is commonly assumed that the infant with colic has distress and possible pain. In recent investigations, it has been found that sucrose has an analgesic effect in newborn infants. The purpose of this study is to examine if sugar solution as sucrose also has an analgesic effect on infant colic. Methods : This prospective randomized, double-blind placebo controlled study examined healthy term infants aged 4 to 12 weeks with colic. A total of 40 infants were randomly assigned into two groups who visited Daedong Hospital from June 1999 to June 2001. Each group received sugar solution or sterile water. All data from parental diaries and interviews were recorded and analysed blindly. Results : The daily crying time and the colic improvement score were significantly better in sugar solution group as compared with the control(P=0.019, 0.045). No significant differences were noted between groups regarding the number of night wakenings(P=0.173). Conclusion : We conclude that sugar solution has an analgesic effect on infantile colic.

We established the first complete ice core processing method and analytical procedures for fundamental proxies, using a 40.2 m long ice core drilled on the Mt. Tsambagarav glacier in the Mongolian Altai mountains in July 2008. The whole core was first divided into two sub ice core sections and the measurements of the visual stratigraphy and electrical conductivity were performed on the surface of these sub core sections. A continuous sequence of samples was then prepared for chemical analyses (stable isotope ratios of oxygen ($^{18}O/^{16}O$) and hydrogen ($^2H/^1H$), soluble ions and trace elements). A total of 29 insoluble dust layers were identified from the measurement of visual stratigraphy. The electrical conductivity measurement (ECM) shows 11 peaks with the current more than 0.8 ${\mu}A$ Comparing the profiles of $SO_4{^{2-}}$ and $Cl^-$ concentrations to correlate with known volcanic eruptions, the first two ECM peaks appear to be linked to the eruptions (January and June 2007) of Kliuchevskoi volcano on the Kamchatka Peninsula of Russia, which supports the reliability of our ECM data. Finally, the composition of stable isotopes (${\delta}^{18}O$ and ${\delta}D$) shows a well-defined seasonal variation, suggesting that various chemical proxies may have been well preserved in the successive ice layers of Tsambagarav ice core. Our ice core processing method and analytical procedures for fundamental proxies are expected to be used for paleoclimate and paleoenvironmental studies from polar and alpine ice cores.

The goal of the present study is to identify the topic trend in the field of library and information science in Korea. To this end, we collected titles and s of the papers published in four major journals such as Journal of the Korean Society for information Management, Journal of the Korean Society for Library and Information Science, Journal of Korean Library and Information Science Society, and Journal of the Korean BIBLIA Society for library and Information Science during 1970 and 2012. After that, we applied the well-received topic modeling technique, Latent Dirichlet Allocation(LDA), to the collected data sets. The research findings of the study are as follows: 1) Comparison of the extracted topics by LDA with the subject headings of library and information science shows that there are several distinct sub-research domains strongly tied with the field. Those include library and society in the domain of "introduction to library and information science," professionalism, library and information policy in the domain of "library system," library evaluation in the domain of "library management," collection development and management, information service in the domain of "library service," services by library type, user training/information literacy, service evaluation, classification/cataloging/meta-data in the domain of "document organization," bibliometrics/digital libraries/user study/internet/expert system/information retrieval/information system in the domain of "information science," antique documents in the domain of "bibliography," books/publications in the domain of "publication," and archival study. The results indicate that among these sub-domains, information science and library services are two most focused domains. Second, we observe that there is the growing trend in the research topics such as service and evaluation by library type, internet, and meta-data, but the research topics such as book, classification, and cataloging reveal the declining trend. Third, analysis by journal show that in Journal of the Korean Society for information Management, information science related topics appear more frequently than library science related topics whereas library science related topics are more popular in the other three journals studied in this paper.

This study estimated characteristics and genetic parameters for milking traits in Holstein dairy cattle. Daily records (12,561) were available from a hundred fifty four lactating cows with sixty six sires at National Livestock Research Institute from November, 2005 to April, 2006. The cows were fed same rations, and were milked twice daily using milking parlour equipped with Alpro-system?? to collect milking records automatically. The experimental cows have averaged 1.9 parities, 139.7 days in milk, and 13kg milk yield per milking. Average milk flow was 64% of peak milk flow. Milking duration, peak milk flow, average milk flow, and milk yield per milking were 5.57±1.67 minutes, 3.58±0.79kg/minute, 2.28±0.51kg/minute, and 13.02±4.09kg, respectively. All traits in the morning milking were higher than those of in the evening milking, and were also increased with parity. Heritabilities for milking duration, peak and average milk flow, and milk yield per time were 0.49, 0.70 0.58 and 0.36, respectively. The genetic correlations of milking duration with peak milk flow, average milk flow, and milk yield per time were 0.48, 0.54, and 0.41, respectively. The correlations of milk yield per milking with peak milk flow and average milk flow were 0.23 and 0.30, respectively. In conclusion, milk flow was increased with milk yield; however milk flow was opposite relationship with milk duration. Further studies are not only necessary to warranty genetic parameters, but pre-installation of automatic recording system to collect daily milking record is also necessary.
Objectives: This clinical study investigates the status of psychiatric consultation from 2001 to 2003 at Maryknoll General Hospital, located in Busan to evaluate the characteristic patterns of current psychiatric consultation and to contribute for further data of consultation study. Methods : The subjects of this study were hospitalized at Maryknoll General Hospital from 1 January, 2001 to 31 December, 2003, who were referred for psychiatric consultation during hospitalization. This study was analysed demographic data, reason for referral, psychiatric diagnosis by patient's chart and psychiatrist's report retrospectively. Results : 1) The psychiatric consultation rates was 1.72%. 2) There was 47.8% in referral among the age group over 60 years, especially the age group over 70 years was 20.3%. 3) The most frequent referral source was department of internal medicine(72.5%). 4) The frequency of psychiatric consultation was the highest at March and the lowest at December. 5) The reasons of psychiatric consultation, according to frequency, were affective change, somatic symptom without abnormal finding. And drug intoxication. alcohol problem were increased. 6) Somatoform disorder was the most common psychiatric diagnosis followed by depressive disorder, organic mental disorder. The diagnosis of somatoform disorder, depressive disorder, alcohol dependence were increased, but anxiety disorder, organic mental disorder were decreased. 7) Pharmacotherapy was the most recommendation, and diagnostic procedure and psychotherapy were increased. Conclusion : In review of consultation referral subjects, the referral rate was 1.72%. The consultation referral of the old(over 60 years) was 42.8%, and annually increased. The most frequent request source was from department of internal medicine. The reasons of consultation referral was the most due to affect change. The recommendation of pharmacotherapy was the most numerous. and psychotherapy was increased annually. Further studies warranted on geriatric psychiatric consultation, pattern change of consultation.

Objectives : Delirium is a disorder defined as a sudden disturbance in thinking, speaking, acting and sleep pattern due to altered level of consciousness and cognitive function. The objective of this study is to analyze characteristics and therapeutic methods of the delirious patients during the recent 5 years, and provide basic data for further studies and investigation regarding delirium in the occurrence and treatment. Methods : We retrospectively reviewed medical records of 475 patients who were consulted for delirium in Kyunghee University Medical Center from January 2007 to December 2011. Results : During the 5 years, among the 475 patients who were diagnosed as delirium, men were more common(61.7%). The most commonly consulted reason and cause were sleep disturbance(80.8%) and post-operational delirium(30.9%), respectively. The medication prescription percentage was 76.6% and was significantly increased year after year. Ratio of using antipsychotics were 76.4% among prescribed medication and the most frequently prescribed antipsychotic drug was quetiapine(46.8%). Other specialists commonly misdiagnosed delirium when the patient was previously diagnosed as dementia(6.8%). Conclusions : In our study, post-operational delirium was the most commonly referred reason and the percentage of medication prescription tended to increase. Patients with history of dementia were more easily misdiagnosed as diseases other than delirium. Our study suggests that we should evaluate symptoms, causes, reasons of consultation, management tendency of delirium. We should also closely observe changes in sleep patterns and establish the prevention strategies for post-operational delirium and therapeutic bases for pharmacotherapy.
Purpose : This study was designed to document the etiologies and the characteristics of parapneumonic effusion in children. Methods : During a 17-year period from 1987 to 2004, parapneumonic effusion was confirmed in 86 children at Gyeongsang National University Hospital. The clinical records of these children were reviewed and radiological findings and laboratory data, especially results of thoracentesis, were analyzed retrospectively. Results : M. pneumoniae(34 subjects) was the most common pathogen at all over age, especially above 1-years-old. There were diagnosed with clinical characteristics and serologic tests. The $2^{nd}$ most common pathogen revealed non tuberculous bacteria(14 subjects). A species of bacteria at no tuberculous bacteria revealed S. aureus(5), S. pneumoniae(3), P. aeroginosa(3), other staphylococcus (2), and K. pneumoniae(1). There were confirmed with sputum culture or pleural fluid culture or blood culture. S. aureus was most common pathogen in infants. The $3^{rd}$ common pathogen was M. tuberculosis(7). There were confirmed with skin tuberculin tests and AFB stains. Another that was classified as a non bacteria was adenovirus(2). Complications of parapneumonic effusion such as pleural thickness occurred on M. tuberculosis(1). Non tuberculous bacteria, especially S. aureus revealed a serious predominance of polymorphocyte at pleural fluid, and lowest pleural pH and glucose, and highest pleural protein and LDH. Tuberculosis revealed high pleural protein and LDH. Conclusion : Age and chemistries of pleural fluid might be helpful in differentiating various etiologies of parapneumonic effusion. If there were suspicious of tuberculosis and non-tuberculous bacteria, more aggressive approaches were needed to prevent complication.

Purpose : For the early diagnosis of Henoch-Schonlein purpura(HSP) presenting with acute abdominal pain preceding skin rash. Methods : The clinical, endoscopic and radiological records of 23 cases of HSP, presenting with gastrointestinal symptoms preceding skin rash were reviewed. Results : The intervals from the onset of abdominal pain to the development of the skin rash were one day to 30 days(median five days), most of them were within two weeks. The presenting abdominal symptoms were abdominal pain(23 cases), vomiting(16 cases), hematochezia or melena(eight cases) and hematemesis(three cases). The abnormal endoscopic findings include coalescing erythematous lesions, areas of submucosal hemorrhage and superficial erosions and ulcers. The upper gastrointestinal endoscopy showed the abnormalities in 21 of 23 cases, which were observed in the duodenum( 21 cases), the stomach(12 cases) and the esophagus(one case). Duodenitis with hemorrhage and/or erosions in the descending duodenum was the sole endoscopic abnormality in two cases and was the most marked finding in three cases. Sigmoidoscopy showed the abnormalities in six of eight cases. The abdominal ultrasonogram showed abnormalities in 12 of 17 cases, which included small bowel wall thickening(eight cases) and intramural hemorrhage(three cases). Recurrences after three months of symptom free intervals developed in four cases; three of them had persistent nephritis beyond one year. Conclusion : The erosive hemorrhagic duodenitis in the descending duodenum in the upper endoscopy and the small bowel wall thickening in the abdominal ultrasonogram can be useful findings in the diagnosis of HSP presenting with acute abdomen.
Purpose : To determine the clinical association of diagnostic criteria and the prevalence of autoantibodies in newly diagnosed children with juvenile dermatomyositis(JDM). Methods : Thirty-two children with JDM were identified at Seoul National University Children's Hospital from March 1985 to March 1999 by retrospective review. The diagnosis of JDM was based on the criteria proposed by Bohan and Peter. We investigated for the presence of several autoantibodies: antinuclear(ANA), double-stranded DNA, anti-Sm, anti-ribonucleoprotein(RNP), anti-SSA/ SSB, anti-Jo1, anti-Scl-70 antibodies and rheumatoid factor(RF). Results : Sex ratio and age at diagnosis were similar to data published in other studies. All the newly diagnosed children with JDM had a typical rash(100%) and proximal muscle weakness(100%); 17(53%) had muscle pain or tenderness; 10(31%) calcinosis; eight(25%) dysphagia; eight(25%) arthritis, and seven(22%) fever. Muscle enzymes were elevated in 90% of the patients. Of the 27 patients who had an electromyogram, 20(70%) had diagnostic results. Sixteen(70%) of biopsied patients had appropriated results for JDM. Patients were negative for all autoantibodies except ANA and RF. ANA and RF were detected in 47% and 7% of the patients respectively. Conclusion : Although the sensitivity of the criteria proposed by Bohan and Peter is superior, each of these criteria has possible confounding factors. Additional criteria may be needed for early diagnosis of JDM. Based on our findings of autoantibodies in JDM, we do not recommend routine testing for autoantibodies in children with typical JDM.
This study was conducted to estimate the effects of year, age of dam at calving, farm and lactation period on milk yield with the data of 4,008 cows' records which were collected at 32 farms by Korea Animal Improvement Association from 1985 to 1989. The results obtained in this study are summarized as follows: 1. The average performance of the dairy cattle in the study were $5,959.23{\pm}2,113.03kg$ in actual milk yield, $49.19{\pm}22.77$ months in age of dam at calving, $27.11{\pm}5.13$ months in age at first calving and $255.11{\pm}79.68$ days in lactation period. 2. The percentages of variance component for different sources were 29.39% for the residuals, 1.91% for years, 4.86% for age at calving, 8.89% for farms and 54.94% for lactation period. 3. The overall mean of least-square estimate on the milk yield was 6,229.31kg. In the effects of year, the least-square means of milk yield were estimated 6,000.76kg in 1985-1987, 6,028.11kg in 1988 and 6,659.07kg in 1989. 4. The least-square means of calving age on the milk yield were estimated 5,456.01kg in less than 24 months, 6,565.48kg in 61-66 months which were the highest least-square means. This effects were gradually increased until the 61-66months and gradually decreased after the 61-66months, with highly significant differences among different months of age at calving(p<0.01). 5. In the effects of farm, the least-square means of milk yield were estimated 4,959.50 kg in the lowest farm and 7,497.07kg in the highest farm. Among the milk yield of each farm the effects showed highly significant difference(p<0.01). 6. The least-square means of milk yield in the effects of lactation period were gradually increased with the lapse of the lactation period. Among the lactation period the effects showed highly significant difference(p<0.01).
