The strain of Nuruk yeat No. 15 (NY-15) which ferments lactose in milk was Isolated from Nuruk and identified as Saccharomyces marxianus according to the API 20C profile index. The lactose hydrolysing ability of NY-15 was similar to that Saccharomyces fragilis ATCC 8583 which has ${\beta}-galactosidase$ activity. Its optimum growth temperature, pH and time for the production of maximum enzyme activity showed $28^{\circ}C$, 4.5 and 28hr, respectively. Galactose as well as sucrose as carbon sources, and urea as nitrogen source Increased the production of enzyme. In order to test the production of alcohol, NY-15 was inoculated in whey medium and whey medium added with sugar. In the former, NY-15 produced 2% alcohol and in the latter, it showed 12% alcohol production. The optimal medium pH for lactose hydrolysis of NY-15 is 4.5, whereas that of Saccharomyces fragilis ATCC 8583 is 3.5

Purpose: The purpose of this study was to identify association between maternal depression and multiple contextual factors in 1,519 mothers in Korea who participated in the 2009 Panel Study of Korean Children (PSKC). Methods: The second wave data which was a comprehensive longitudinal data set with a nationally representative birth cohort was analyzed using SAS 9.3 software. Kessler depression scale was used for this study. Results: Of the mothers, 23.0% reported being mild to moderate depression and 4.5% of the mothers reported severe depression. The factors influencing maternal depression include; mother's self-efficacy, mother's marital conflict, mother's social support, infant's and toddler's emotionality, mother's smoking and infant's feeding & eating of daily routine. These variables explained 39.5% of maternal depression. Conclusion: The results of this study suggest that the identified factors for maternal depression should be included in an intervention program to reduce the risk of depression.

Ureteropelvic junction obstruction is one of the common causes of hydronephrosis in infancy and childhood. Most cases of ureteropelvic junction obstruction are diagnosed prenatally and are usually asymptomatic. Although less common, older children can experience ureteropelvic junction obstruction that presents with symptoms including flank or abdominal pain. Here, we present the case of a nine-year-old healthy girl who had repeated flank pain and abdominal symptoms, with mild left hydronephrosis, for several months. Computed tomography that was performed during the period of acute flank pain revealed aggravated hydronephrosis on her left kidney, which was secondary to an ureteropelvic junction obstruction. She underwent laparoscopic pyeloplasty, and a crossing vessel that passed the ureteropelvic junction was identified. In addition, we reviewed the current literature of this rare entity.

Comparative morphology of the genus Branchiostegus has been investigated based on the specimens collected from the adjacent waters of Korea. Branchiostegus japonicus has a distinctive silvery white triangular marking behind eye, while B. albus has nothing. B. albus has about 4 yellow strips along the posterior margin, however, remainder have 5 to 6 longitudinal yellow stripes. In B. auratus, its head length is more than 26% of standard length, but, less than 26% in B. argentatus. This study reveals that B. argentatus is the first record from Korea, and we propose "T$\check{u}$ng-h$\acute{u}$k-ch$\check{o}$m-ok-tu-$\check{o}$" for B. argentatus as a new Korean name.

A micro organism Agrobacterium tumifacient as an immobilized cell on a solid support was presented as a new biosorbent in a simple and sensitive spectrophotometry determination of Ni(II) in various samples using 4-hydroxy benzaldehyde-4-bromophenyl hydrazone as a color developing agent (λmax 497 nm) at pH 4.0 ± 0.2. Beer's law was obeyed over the range of 0.01-0.1 μg L-1. The molar absorptivity and Sandell's sensitivity were 1.285 × 105 L mol-1cm-1 and 0.007245 μg cm-2 respectively. Under these conditions, the preconcentration factor obtained was 82, and the detection limit achieved was 0.05 μg L-1. The detailed study of various interfering ions made the method more sensitive and selective. The recovery of Ni(II) from various samples range from 97.75 to 99.35%. The present method was successfully applied for the determination of Ni(II) in spiked, natural water and alloy samples. The proposed method was compared with reported methods in terms of Student's ‘t'-test and Variance ratio ‘f'-test which indicates that there is no significant difference between proposed and literature method at 95% confidence level.

This study was designed to report treatment for Behcet's disease with arthritis We treated 2 Behcet's disease patients with arthritis. A 46-year-old female patient was treated with Cheongsimyeonja-tang. Another case, 44-year-old female patient was diagnosed as Sjogren's disease at first and diagnosed as The Behcet's diseases about 1 year later, treated with Cheonglijagam-tang. The progress was evaluated with the visual analogue scale for joint pain and hot flush, and length of sleeping time. There was improvement in the symptoms of visual analogue scale for joint pain and hot flush, also length of sleeping time. Cheongsimyeonja-tang, Cheonglijagam-tang can be considered as a treatment for patient diagnosed as Behcet's disease suffering from arthritis, especially.

The purpose of this study is to examine the causal relationships among knowledge management system(KMS) quality, perceived ease of use, perceived usefulness, attitude, and continuance use of KMS. The results of data analysis by structured equation model(SEM) indicate that KMS quality significantly influences individual's perceived ease of use and perceived usefulness. Perceived ease of use affects individual's perceived usefulness on KMS. Individual's perceived ease of use and perceived usefulness affect on the creation of a positive attitude, and attitude affects continuance use of KMS. Based on the results, theoretical and practical implications of this study are discussed.

Proteins in friable and compact calli of Viola patrinii DC. were analysed. The protein contents in friable calli were lower than those in compact calli. In suspension culture, it increased to the maximum after 3 weeks culture from inoculation and decreased after 4 weeks culture. Several strong lavel signals were detected with the SDS-PAGE analysis. The polypeptides of 28, 31 and 35 KD were observed from the friable cell culture, from the compact cell culture strong band of 30 KD was determined, indicating that these polypeptides may be the major protein occurring during their cultures. Changes in amino acid contents during culture of the viola suspension cells were investigated the amino acid contents were greatest between two and three weeks culture of the viola suspension cells.

Purpose: This study aimed to clarify the factors related to mothers' decisions to provide disease explanations to their children, investigate the associations between those factors and social adaptive skills, and examine support relative to children's growth and development. Methods: Data were collected from anonymous, self-administered questionnaires answered by 71 mothers of outpatient school-aged children with congenital heart disease. The questionnaire items included characteristics of mothers and children, decision factors for providing disease explanations, and children's social adaptive skills (Asahide-Shiki social adaptive skills test). Factor analysis was performed on the decision factors, and multiple regression analysis was performed to examine the association between the identified factors and each social adaptive skill. Results: The decision factors for providing disease explanations were the mother's explanation ability, the receptive capability of the child, and the child's interest and literacy regarding the explanation. Multiple regression analysis showed that language and social life skills were significantly associated with the child's receptive capability, and language and daily life skills were significantly associated with the child's interest and literacy regarding the explanation. Conclusion: Improving children's language, social life, and daily life skills may enhance their receptive capability and literacy regarding explanations of their disease.
