The purpose of this study was to understand the level of depression of children suffering from cancer. The depression was compared with a group of children that were hospitalized due to other disorders and another group of school children that were healthy. The subjects of this study were 30 children who were diagnosed with cancer and were being treated at St. Mary's Hospital. This group of children were compared with a control group of 40 children who were hospitalized in the same hospital for non-cancer diseases and another control group of 200 children with a healthy status. Level of children depression in each group was measured with CDI and was compared to each other groups using ANOVA and Duncan test. To examine the relationship between depression and other variables. correlation coefficients were tested and stepwise multiple regression was used to point out the main cause which had effects on the level of depression. Cronbach's a of CDI in this study was 0.91. The results u·ere as follows: 1. Children with cancer had a depression score of 44.5 which was lower than the control group of healthy school children which scored 49.0 and higher than the non-cancer hospitalized children group scoring 44.2 (F=3.38. P=0.036). 2. Depression level of children with cancer were shown higher as the self-esteem level was lower(r=-0.60, p=0.001). Also, suffice understanding between the children's mother resulted in a lower level of depression(r=-0.57, p=0.001). Level of depression proved a positive correlation with the level of anxiety((r=0.56, p=0.002). 3. The major variables influencing the depression of children with cancer were anxiety which had an explanation of 27.1%, followed by the education level of the children's father 9.3% and the understanding level with the children's mother 8.0% which build up 54.5% of the total account for depression. For the children hospitalized for non-cancerous diseases, the anxiety of the children took 37.5%, self-esteem level 18.2%, age of the children's mother 10.2% adding up a total of 65.9% of the total explanation. For healthy school children, self esteem level 35.6%, anxiety of the children 11.7%, understanding level between the children's father 11.7% built up a 49.4% account for their depression level. Such results show that to reduce the depression level of children suffering from cancer the anxiety level of the subjects should be brought down and at the same time a high level of self-esteem should be maintained. Furthermore, a demand for a nursing system which helps to promote more understanding between the children and children's parents is needed in hand.

Lavandula vera is indispensable member of the herb family, used for perfumes and potpourri. Androgens have profound effects on the physiology of the sebaceous gland. Sebum is secreted due to the effect of androgen, which starts to be secreted at puberty. Using the human sebocyte cell line SZ95, the author investigated the inhibitory effect of Lavandula vera on the lipid production. Light microscopic finding were examined numerous cytoplasmic lipid droplets SZ95 cells by Oil red staining and lipid droplets were increased markedly by testosterone. On the other hand, combined treatment with Lavandula vera and testosterone resulted in a lower lipid droplets than with testosterone alone in a dose-dependent manner. These findings indicate that Lavandula vera acts antagonistically to testosterone and inhibits the lipid synthesis of SZ95 cells at the cellular level.

Whole soybean milk is a functional soymilk produced by mixing of soymilk and Bejee (soymilk residue) slurry. Application of enzymatic technology for disintegrating the coarse and fibrous materials in soymilk residue, and development of biomill reactor for reducing reaciton time make possible to produce new soymilk in domestic industry. Whole soybean milk is environmental affiliated product without discharging any waste such as Bejee ets. Whole soybeen milk has good taste and flavour without coarse mouthfeel induced by including Bejee particle, as well as contains more dietary fiber, protein, oligosaccharide, and other functional compounds than general soymilks. Important values of whole soybean are utilizing all nutritional properites from whole soybean without dicarding any of the insoluble solid. In this study, producing technologies and nutritional properties of whold soybean milk were investigated.

Purpose: To investigate the level of life satisfaction and burden for primary caregivers of patients with dementia in day care centers and in their homes. Method: From August to September 2003, 56 caregivers of patients with dementia in day care centers and 54 caregivers in their homes were surveyed through three questionnaires: Life Satisfaction Index-Z and Korean Dementia Caregiver Burden. Result: Life satisfaction of caregivers in day care centers was significantly higher than that of caregivers in their homes(p<.005). Also, the sense of burden of caregivers in day care centers was significantly lower than that of caregivers in their homes(p<.005). Caregivers in day care centers showed significantly lower levels in four subdimensions of burden than those of caregivers in their homes. The level of life satisfaction of caregivers in day care centers and in their homes were also negatively correlated with the sense of burden(p<.005, p<.005). Conclusion: Using day care centers for patients with dementia will be a good way to take care of them because their primary caregivers can have more rest time and less burden. Therefore, using day care centers for patients with dementia should be recommended and the number of the facility should be increased nationwide.

Doping effects of ZnO quantum dots on the sensitive and selective detection of acetylene for dissolved-gas analysis applications of transformer oil

Park, Min Sun,Lee, Jun Ho,Park, Yunji,Yoo, Ran,Park, Seungryol,Jung, Hwaebong,Kim, Wonkyung,Lee, Hyun-Sook,Lee, Wooyoung Elsevier 2019 Sensors and actuators. B, Chemical Vol.299 No.-

<P><B>Abstract</B></P> <P>We report on the doping effect on the sensing properties of ZnO quantum dots (QDs) for the detection of acetylene. We found that In-doped ZnO (IZO) QDs exhibited a better sensing performance to 10 ppm acetylene than undoped ZnO (ZO) QDs and Al-doped ZnO (AZO) QDs. The higher sensing response of IZO QDs can be attributed to a greater number of reactive sites for detecting acetylene, which is likely to originate from the increased number of oxygen vacancies, and the larger optical band gap and surface area of IZO. This is due to a higher valence dopant and a smaller particle size. The sensing properties of IZO QDs to 10 ppm acetylene was also found to be superior to previously reported acetylene sensors that are based on semiconducting metal oxides. Furthermore, we demonstrated that 10 ppm of acetylene can be selectively detected in air within ∼100 s using a recently developed miniaturized gas chromatography (GC) integrated with the IZO QDs sensor. In addition, we found that the device can detect the major fault gases of hydrogen and acetylene separately within ∼100 s. Our study demonstrates that the device can be utilized in the GC-based on-line dissolved gas analysis to detect small amounts of acetylene gas in transformer oil.</P> <P><B>Highlights</B></P> <P> <UL> <LI> We report the doping effect on the sensing properties of ZnO quantum dots for acetylene. </LI> <LI> Doping of ZnO quantum dots modified oxygen vacancies and optical band gaps. </LI> <LI> In-doped ZnO quantum dots exhibited a better sensing performance to 10 ppm acetylene. </LI> <LI> 10 ppm acetylene could be selectively detected using a miniaturized gas chromatography. </LI> <LI> The device can detect the major fault gases of hydrogen and acetylene separately within ∼100 s. </LI> </UL> </P>

Park, Joon-Sik,Han, Jungho,Shin, Jeong Eun,Lee, Soon Min,Eun, Ho Seon,Park, Min-Soo,Park, Kook-In,Namgung, Ran The Korean Pediatric Society 2017 Clinical and Experimental Pediatrics (CEP) Vol.60 No.3

Purpose: The goal of nutritional support for very-low-birth-weight (VLBW) infants from birth to term is to match the in utero growth rates; however, this is rarely achieved. Methods: We evaluated postdischarge growth patterns and growth failure in 81 Korean VLBW infants through a retrospective study. Weight and height were measured and calculated based on age percentile distribution every 3 months until age 24 months. Growth failure was defined as weight and height below the 10th percentile at 24 months. For the subgroup analysis, small-for-gestational age (SGA) and extremely low birth weight (ELBW) infants were evaluated. The growth patterns based on the Korean, World Health Organization (WHO), or Centers for Disease Control and Prevention (CDC) standard were serially compared over time. Results: At postconception age (PCA) 40 weeks, 47 (58%) and 45 infants (55%) showed growth failure in terms of weight and height, respectively. At PCA 24 months, 20 infants (24%) showed growth failure for weight and 14 (18%) for height. Growth failure rates were higher for the SGA infants than for the appropriate-weight-for-gestational age infants at PCA 24 months (P=0.045 for weight and P=0.038 for height). Growth failure rates were higher for the ELBW infants than for the non-ELBW infants at PCA 24 months (P<0.001 for weight and P=0.003 for height). Significant differences were found among the WHO, CDC, and Korean standards (P<0.001). Conclusion: Advancements in neonatal care have improved the catch-up growth of VLBW infants, but this is insufficient. Careful observation and aggressive interventions, especially in SGA and ELBW infants, are needed.
