Objectives and Methods:This study investigated clinical characteristics, treatment modality, outcome of 57 children and adolescent inpatients(male 53, female 4) who were diagnosed as pervasive developmental disorder(PDD) by DSM-Ⅳ criteria recent five years. Results:1) The mean age at admission was $96{\pm}28.2$ months, and the mean age at which they first visited treatment facility was $52{\pm}26.6$ months. The mean hospitalization period was $43.7{\pm}31.3$ days. 2) Diagnosis:Twenty-seven(47.4%) of subjects met DSM-Ⅳ criteria for PDD NOS. Fifteen (26.3%) met for autistic disorder, nine(15.8%) met for Asperger's syndrome, and two(3.5%) met for childhood disintegrative disorder. 3) Comorbid diagnosis:The most common comorbid dignosis was attention deficit hyperactivity disorder(23.8%). 4) IQ test:IQ test for twenty-eight subjects was possible. The Average of the subjects was $70{\pm}27.5$. Fifteen(53.6%) of the subjects were approximate or under 70. 5) Neurology Abnormality:EEG findings of eleven(21.2%) subjects were abnormal, brain CT or MRI findings of eight subjects(21.6%) were abnormal. 6) Family Hx:Depressive disorder were found in Eight mothers(14%). Familial loading was found in twenty families(35.1%), and familial loading of PDD was found in three(5.3%). Conclusion:The most important thing for the management of PDD is early detection and early treatment. To do so, multidisciplinary team approach should be emphasized.
What are the international aviation regimes? It is said that they are sets of principles, norms, rules, and decision-making procedures of international aviation around which aviation actors' (states-actors, intergovernmental aviation organization, international aviation conventions, airlines and their organizations etc.) expectations converge in a given aviation issue-area for the purposes of the human welfare and the operations of the stable civil aviation. In this regards, the purposes of this study are focused on the aviation actors' shifts. Chronologically, international aviation regimes have been developed by some stages as followings; The 1st stage is the period from 1944 Chicago Convention to 1978 US Deregulation Act, when the aviation regulations and rules within the international aviation relations were implemented by Chicago-Bermuda regimes as Christer Jonsson pointed out. In this first stage, the sovereignty for the airspace over their countries is absolute. The second stage is the period from 1978 to '1992 Open Skies Agreement' between US and Netherlands. In this regime, airlines' activities as well as state-actors' have been actuated. The third stage is the period from 1992 to the contemporary. In this stage, airlines' activities for the consumers such as 'Open Skies Agreements', 'e-commerce business', 'airspace open policy within EU area', 'service open policy of WTO', and 'airlines' strategic alliance' are the central focal points in the world aviation relationship. In the conclusion, this phenomenon of the core actors in the international aviation rules has been shifted from the states-actors to the non-states actors especially, operating airlines, or consuming customers. Finally, I' d like to suggest that international aviation regimes should be developed to promote and facilitate the globalized level for the people's movements among the global aviation society. That is the way to proceed to the welfare and peace for all human beings of the World.
This study was carried out to determine the effect of dietary supplementation of resveratrol and methoxylated resveratrol extracted from branch of Morus alba L. on the quality of chicken thigh meat during cold storage. For 35 days, 1-day-old 320 broiler chicks (Ross) were divided into 8 groups and supplemented the diet; basal diet only (BD), BD with antibiotics (AB), vitamin E 20 IU (VE 20), vitamin E 200 IU (VE 200), resveratrol 20 ppm (RV 20), resveratrol 200 ppm (RV 200), methoxylated resveratrol 20 ppm (MR 20), and methoxylated resveratrol 200 ppm (MR 200). After slaughtering the broilers, thighs were collected and analyzed the quality change of the meat during storage at $4^{\circ}C$ for 5 days. The meat quality factors such as pH, color, water holding capacity, and sensory characteristics of thigh meat were determined on the experiment day 1, 3, and 5. AB, VE, and MR increased pH value of chicken thigh compare to BD (p<0.05). Lightness ($L^*$) showed no significant difference during storage day 1 and 5. VE 200 and MR 20 stabilized the redness ($a^*$) of chicken thigh as the value of day 1. Water holding capacity of chicken thigh from VE 20, RV 200, MR 20, and MR 200 on storage day 3 was higher than that of BD (p<0.05). In sensory evaluation, the panelist discriminated the tenderness and gave the higher score on the chicken from AB, VE20, RV 20, and MR 20 compare to BD (p<0.05). These results suggest that the dietary resveratrol and methoxylated resveratrol could be used as chicken meat quality enhancer in broiler industry.

Purpose : Staphylococcal scalded skin syndrome (4S) is a well known disease defined by clinical, microbiological and histological criteria caused by Staphylococcus aureus. This disease is uncommon but has been increasingly recognized. We investigated the clinical features of staphylococcal scalded skin syndrome. Methods : We reviewed retrospectively medical records of 53 patients diagnosis of staphylococcal scalded skin syndrome who were admitted to Changwon Fatima hospital from February 2002 to December 2005. These patients were divided into 3 clinical types; generalized type, intermediate type, abortive type. Age, sex ratio, clinical manifestations, laboratory findings, response to therapy and prognosis were investigated. Result : 1)The mean age of patients was 2.8 years, ranging from 20 days to 7 years. Male-to-female ratio was 1.9:1. 2) By clinical types, 6 patients were in the generalized type (11%), 29 patients in the intermediate type (55%), 18 patients in the abortive type (34%). The coexisting diseases were variable, including conjunctivitis (25 cases), atopic dermatitis (11 cases), otitis media (1 case). On laboratory findings, most of patients didn't have leukocytosis or increased C-reactive protein. 4) A total of fifteen Methicillin Resistant Staphylococcal Aureus (MRSA) strains were isolated from September 2003 through December 2005. Fourteen strains were positive for exfoliative toxin B gene by PCR and negative for enterotoxin, toxic shock syndrome toxin and Panton-Valentine leukocidin genes. 5) The mean duration of admission was 7.3 days. Patients were treated with vancomycin or amoxacillin/clavulanate or ampicillin/sulbactam or cefuroxime without significant sequelaes. Conclusion : Recently, Staphylococcal scalded skin syndrome caused by exfoliative toxin B produced by MRSA in the Changwon area has been increasing.

For the purpose of investigation of demersal fisheries resources of the East China Sea, joint research between Hokkaido University and National Fisheries University of Pusan was carried out during the period from November 5 to November 12 in 1989. This joint research is due to continue for the next three years. In this report, the authors analyzed the catch of 24 draughts of trawl operating by the Oshorumaru of the training ship of Hokkaido University in the north area of the East China Sea, in order to hold the present condition of the demersal resources. The specimens collected were composed of 76 species of fishes, 6 of mollusca and 7 of crustacea. And the main species of the large catch were Raja kenojei, Zeus faber, Miichthys miiuy, Collichthys lucidus, Dentex tumifrons, Carangoides caeruleopinnatus, Trachurus japonicus, Parastromateus niger, Trichiurus leptulus, Scomberomorus niphonius, Pampus argenteus, Pampus echinogaster, Psenopsis anonala, Liparis tanakai, Thammaconus modestus, Tadarodes pacificus, Loligo edulis, and Portunus trituberculatus. Especially, Trichiurus leptulus, Pampus agrenteus and Thammaconus modestus had different modes of classes of body size individually, with changing of fishing ground. But, Tadarodes pacificus, Loligo edulis and Portunus trituberculatus were caught the maxed sizes of body individually in the same ground.
This study was carried out to develop natural vinegared kochujang. We first formulated vinegared kochujang containing pine needle (PN) and Artemisia princeps (AP) extracts. A dominant strain was isolated from the vinegared kochujang and identified as Bacillus amyloliquefaciens ER282 based on the 16S rDNA sequence. The plant extracts of PN and AP were also investigated for their antibacterial activity and showed enough good activities to use for vinegared kochujang as a natural preservative. Quality characteristics of vinegared kochujang were evaluated, based on total cell numbers, pH, acidity, sugar content, color and sensory evaluation during storage at $25^{\circ}C$ and $37^{\circ}C$, respectively, for 3 weeks. No significant differences were found in the pHs and acidities of vinegared kochujang added with the plant extracts of PN and AP during their storage compared to starting time; however, total cell numbers were gradually decreased during the storage at $25^{\circ}C$ and $37^{\circ}C$, as the storage period was increased. For sensory evaluation, overall preference continuously declined depending on storage period, but the addition of 3% extracts of PN could delay the quality loss of vinegared kochujang during storage at $25^{\circ}C$ and $37^{\circ}C$ for 3 weeks.
Background: Recently, multidrug-resistant (MDR) A. baumannii has been implicated for a significant proportion of nosocominal pneumonia in many intensive care units (ICUs), and its acquisition may increase mortality and the length of stay in the ICU. Aerosolized colistin has been successfully used in patients with cystic fibrosis, but there is a lack of data regarding the use of aerosolized colistin in patients with nosocomial pneumonia. Methods: We conducted the present study to assess the effectiveness of aerosolized colistin for the treatment of MDR A. baumannii nosocomial pneumonia. We retrospectively reviewed the medical records of 10 patients who had been hospitalized in the medical ICU and had received aerosolized colistin as a therapy for MDR A. baumannii pneumonia. Results: The mean duration of aerosolized colistin therapy was $12.7{\pm}2.4$ days. Nine (90%) of 10 patients showed a favorable response to the therapy. Follow-up cultures were available for all patients, and the responsible pathogen was completely eradicated. One patient suffered from bronchospasm, which resolved after treatment with nebulized salbutamol. Conclusion: Our results corroborate previous reports that aerosolized colistin may be an effective and safe choice for the treatment of nosocomial pneumonia caused by MDR A. baumannii. Larger prospective controlled clinical studies are warranted to validate further the effectiveness and safety of aerosolized colistin therapy.

The purpose of this work was to examine the effect of peptide on blood pressure and serum lipid concentration of spontaneously hypertensive rat(SHR). This peptide was extracted from beef muscle hydrolysates and identified as hexapeptide, V-L-A-Q-Y-K. This peptide showed angiotensin converting enzymc(ACE) inhibition activity in vitro experimentation$(IC_50: I38.34{\mu}\ell$/ml). Diets containing 0.2g. 0.5g. and 1.0g of the peptide per kg body weight were fed to SHR every day for 8 weeks while the control group was ted on a diet and lml of drinking water instead of the peptide. Total cholesterol and LDL-cholesterol concentrations of the treatment groups were lower than those of the control diet feeding group. The significant suppression of systolic blood pressure was shown by increasing the concentration of peptide supplement. especially by 3 weeks of feeding. although it started fluctuating later. These results suggest that the peptide may beneficially affect blood pressure in spontaneously hypertensive rat by the 3-week administration.

Purpose: Enterovirus (EV) infection in children can manifest various diseases from asymptomatic infection to nonspecific febrile illness, hand-foot-mouth disease, and aseptic meningitis. This study was aimed to investigate epidemiology and clinical significance of various genotypes of EV infections in pediatric inpatient. Methods: We collected the stool samples from the admitted pediatric patients in Inha University Hospital from March 2014 to March 2015. EV detection and genotype identification were performed by real-time RT-PCR and semi-nested RT-PCR. Phylogenetic trees were constructed by neighbor joining method. Results: A total of 400 samples were collected during study period and 112 patients (28%) were diagnosed with EV infections. The mean age of EV positive patients was 2.66 years (0.1-14) and sex ratio was 1.73:1. Genetic sequences of EVs were identified; coxsackievirus B5 (17, 15.2%), coxsackievirus A16 (13, 11.6%), enterovirus 71 (10, 8.9%), and coxsackievirus A2 (9, 8.0%). Nonspecific febrile illness (96, 86%) was the most common clinical manifestation and the duration of fever was 0-11 days (mean 3.1 days). Rash (44, 39%) and meningitis (43, 38%) were followed. Patients who were attending daycare center or had siblings accounted for 82.1%. Phylogenetic relationship tree revealed 6 distinct genogroups among 56 types of EVs. Conclusions: This study is the report of epidemiology, serotype distribution and clinical manifestations of children with EV infection in Incheon. This data will be helpful for further study about the epidemiology of EV infection in Korea.
This study was carried out to investigate for resistance of V. parahaemolyticus that isolated from patients of food poisoning and fish and shellfish, captured in east coast of Kyungpook province of Korea from 1985 to 1986. VP ATCC 17802 and NAG V. ATCC 6538 were used as control. In fish, shellfish and seaweed, the more temperature increased, the shorter survival time was. In case of sea-water, the more temperature rose up, the longer survival time was, particularly in $37^{\circ}C$ and $25^{\circ}C$, the strains had survived after 6 months. And in tapwater, it was sterilized in 150 mins. and survived for 11.5 days on maximum in ground water. In kimchi, at room temperature, germicidal time was shorter more than 6 times compared with that which had been kept in refrigerator. It survived for 57.1 days in milk, 49.2 mins. in yougurt. Strains had been surviving in frozen condition at $-70^{\circ}C$ even after 6 months, present study time. In resistance test in water bath at several degrees of temperature, all the strains were sterilized in 20 mins. with $60^{\circ}C$. In resistance test to driness, number of surviving strains dropped rapidly in 10-11%) water contents. In UV $2538{\AA}$, strains were sterilized in 20 mins. In resistance test to alcohol, strains had survived for 0.1-4 mins. in fermentative wine of below than 25% and distilled wine of over than 25% in alcohol concentration. The bactericidal concentration of disinfectant was 1% in phenol and 3% in cresol. In 0.1M acetic acid and 0.1M lactic acid, number of surviving colonies decreased rapidly but not in citric acid. The more NaCl concentration rose up, the lower decreasing rate of number of surviving colonies was. The strains had showed sensitive response to vancomycin, chloramphenicol, gentamicin, and resisted to carbenicillin, ampicillin and kanamycin. When one day culture strain was cultured till 25th day, resistant strains to tetracycline and cephalothin were changed to sensitive.
