The effects of charcoal powder on fermentation of dough and quality of bread were investigated. Charcoal powder was added to wheat flour at concentrations of 0, 0.05, 0.10 and 0.20%. The fermentation time of dough with charcoal was reduced by 4~12 min compared with that of dough without charcoal. The loaf volume index of bread with 0.05% charcoal powder slightly increased. Bread with charcoal powder showed higher textural properties (strength, hardness, springness, gumminess, and brittleness) except for cohesiveness than bread without charcoal powder. Color L^(*) and b^(*) values and hue angle of the top crust decreased while a^(*) value increased with increasing charcoal concentrations. L^(*) and a^(*) values of the inside of bread decreased while hue angle increased with increasing charcoal concentrations. No significant difference in pleasant taste between bread with and without charcoal powder was observed. However, bread with 0.1% charcoal powder showed the highest scores for pleasant odor, color, and overall acceptability.

Eight monitoring stations in the Yeosu National Industrial Complex will determine the concentration of air pollutants measured every hour in 2019, analyze what factors affect them, and how they correlate with the air pollutant measurements. Six air pollutants (SO2, NO2, O3, CO, PM-10 and PM-2.5) measured at eight monitoring stations around Yeosu National Industrial Complex (Seogang-dong, Wolnae-dong, Munsu-dong, Yeocheon-dong, Deokchung-dong, Hwayang-myeon, Yulchon-myeon, Samil-dong) the measurement data for each hour of the year were downloaded to analyze the concentration by weather condition, time zone, season, separation distance from Yeosu Industrial Complex, and separation distance from Gwangyang Industrial Complex. SO2, NO2, and CO concentrations were significantly higher in winter, significantly lower in summer, and O3, PM-10, and PM-2.5 concentrations were significantly higher in spring. SO2, CO, PM-10, and PM-2.5 concentrations were significantly higher between 10 a.m. and 12 p.m., NO2 concentrations were significantly higher between 7 a.m. and 9 a.m., and O3 concentrations were significantly higher between 13 p.m. and 15 p.m.(p<0.001). The concentration of air pollutants (SO2, NO2, CO, PM-10, PM-2.5) excluding O3 was found to have a negative (-) correlation with weather condition, and in the case of O3, it was found to have a positive (+) correlation with PM-10, PM-2.5, temperature and wind speed. It was confirmed that the concentration of air pollutants emitted from the Yeosu National Industrial Complex differs depending on the season, time and distance to the industrial complex. This study aims to establish measures to minimize health damage to residents living relatively close to the industrial complex and contribute to the establishment of management and response measures according to the properties of substances to reduce the concentration of air pollutants in the future.

Purpose: The purpose of this study was to understand the degree of depression, sleep quality, job stress and their association among office workers. Method: A self-administered questionnaire was distributed to 147 workers employed in 5 big enterprises, and 5 small and medium enterprises from October 21 to November 21, 2012. The questionnaires included socio-demographic and health-related characteristics, job-related characteristics, sleep quality, job stress (KOSS) and depression (CES-D). Result: Among all subjects, 23.1% was in the depression group (21 points and over in the CES-D score). Depressive level was positively correlated with job stress and quality of sleep. The adjusted odd ratio for the effects of sleep quality and job stress on depression significantly increased in the depression group compared to that of the normal group. Multiple regression analysis revealed that the following factors of influence had combined explanatory powers on depression: BMI, life satisfaction, quality of sleep, and job stress. Conclusion: The study revealed that complicated influences were exerted on the level of depression by variable factors, as well as socio-demographic characteristics, health-related characteristics, quality of sleep, and job stress. Specifically, the level of depression was influenced by the quality of sleep and job stress.

Excessive nitrogen fertilization influences crop yields and quality as well as environmental pollution. In this study, yields, nitrogen use efficiency and free sugar contents of burdock (Arctium lappa L.) were evaluated at different levels of nitrogen fertilization. Nitrogen fertilizer was applied at 5 levels (0, 50, 100, 150, 200%) based on the conventional fertilization ($N=230kg\;ha^{-1}$), and phosphate and potassium fertilizer were treated by conventional P and K fertilization ($P_2O_5-K_2O=140-210kg\;ha^{-1}$) in all plots. The root yields of burdock were the highest in N 100~150% treatment plots. Nitrogen use efficiency and nitrogen recovery decreased from over N 150% treatment. Nitrogen uptake of root was greater than that of shoot in N 50~200% treatments. Fructose contents in root were inversely proportional to the level of nitrogen fertilization. As considering nitrogen recovery and root quality, economical burdock yield was obtained in N $230kg\;ha^{-1}$.

Ye-Jin Lee,Jwa-Kyung Sung,Seul-Bi Lee,Jung-Eun Lim,Yo-Sung Song,Deog-Bae Lee,Suk-Young Hong 한국토양비료학회 2017 한국토양비료학회지 Vol.50 No.2

Analysis of mineral nutrients in plant is required for evaluating diagnosis of plant nutritional status. Pretreatment procedure for the analysis of plant can be varied depending on elements to be analyzed. Wet-digestion is suitable for total nitrogen, phosphate and cations, however, digestion solution including nitric acid is not suitable for nitrogen analysis. Incineration procedure is required to analyze chloride, silicate and total sulfur. After digestion, total nitrogen is analyzed by Kjeldahl method, and phosphate is detected at 470nm by colorimetric analysis with ammonium meta vanadate. Cations and micro elements are determined by titration or colorimetry, also, these elements can be measured by Atomic absorption spectrometer (AAS) or Inductively coupled plasma spectrometer (ICP).

Background: For children and adolescents with cancer, going back to school is a key milestone in returning to "normal life." Purpose: To identify the support vital for a successful transition, we evaluated the parents' needs and the challenges they face when their children return to school. Methods: This multi-institutional study was conducted by the Korean Society of Pediatric Hematology and Oncology. The written survey comprised 24 questions and was completed by 210 parents without an interviewer. Results: Most parents (165 of 206) reported that their children experienced difficulties with physical status (n=60), peer relationships (n=30), academic performance (n=27), emotional/behavioral issues (n=11), and relationships with teachers (n=4) on reentering school. Parents wanted to be kept informed about and remain involved in their children's school lives and reported good parent-teacher communication (88 of 209, 42.1%). Parents reported that 83.1% and 44.9% of teachers and peers, respectively, displayed an adequate understanding of their children's condition. Most parents (197 of 208) answered that a special program is necessary to facilitate return to school after cancer therapy that offers emotional support (n=85), facilitates social adaptation (n=61), and provides tutoring to accelerate catch up (n=56), and continued health care by hospital outreach and school personnel (n=50). Conclusion: In addition to scholastic aptitude-oriented programs, emotional and psychosocial support is necessary for a successful return to school. Pediatric oncologists should actively improve oncology practices to better integrate individualized school plans and educate peers and teachers to improve health literacy to aid them in understanding the needs of children with cancer.

Lee, Ye-Jin,Sung, Jwa-Kyung,Lee, Seul-Bi,Lim, Jung-Eun,Song, Yo-Sung,Lee, Deog-Bae 한국토양비료학회 2016 한국토양비료학회지 Vol.49 No.4

The objectives of fertilizer recommendation are to prevent the application of excessive fertilization and to produce target yields. Also, optimal fertilization is important because crop quality can be influenced by fertilization. In this study, yields and fertilizer use efficiency of Taro (Colocasia esculenta Schott) were evaluated in different level of NPK fertilization. N, P and K fertilizer application rates were 5 levels (0, 50, 100, 150, 200%) by practical fertilization ($N-P_2O_5-K_2O=180-100-150kg\;ha^{-1}$), respectively. In the N treatment, the yields of Taro tuber were about $33Mg\;ha^{-1}$ from 90 to $360kg\;ha^{-1}$ N fertilization. However, the ratio of tuber to total biomass decreased with increasing N fertilization rate. In the P and K treatments, yields of Taro tuber were the highest at $150kg\;ha^{-1}$ fertilization. Fertilizer use efficiency was decreased by increase of N and K fertilization. Crude protein of Taro tuber was the highest at practical fertilization. Sucrose content of tuber was influenced by phosphate application.

<P><B>Abstract</B></P> <P>Umbelliferone (UMB) is a coumarin derivative present in roots and barks of plants, such as <I>Angelica decursiva</I>, <I>Artemisia capillaris</I>, and orange. UMB has been previously reported to exhibit anti-inflammatory, anti-diabetic, and anti-cancer effects. However, the effect of UMB on atopic dermatitis (AD) remains unknown. The purpose of this study was to investigate the anti-atopic effects of UMB on 2,4-dinitrochlorobenzene (DNCB)- and house dust mite extract (<I>Dermatophagoides farinae</I> extract, DFE)-treated mice with AD-like skin lesions and on tumor necrosis factor (TNF)-α/interferon (IFN)-γ-treated HaCaT cells. In DNCB/DFE-treated mice, oral administration of UMB (20 and 40 mg/kg) for 28 days led to a significant decrease in ear thickness, spleen size and weight, serum levels of immunoglobulin E (IgE), IgG1, IgG2a, TNF-α, and interleukin 4 (IL-4), and mast cell infiltration; it also led to the suppression of pro-inflammatory cytokines and chemokines. In addition, UMB reduced the secretion of pro-inflammatory cytokines and chemokines in TNF-α/IFN-γ-treated HaCaT cells via regulation of MAPK, IkB-α/NF-κB, and STAT1 signaling pathways. Taken together, these results indicate that UMB ameliorates AD-associated symptoms and inflammation via regulation of various signaling pathways, suggesting that UMB might be a potential therapeutic agent of AD.</P> <P><B>Highlights</B></P> <P> <UL> <LI> Umbelliferone ameliorates DNCB/DFE-induced AD-like skin lesion symptoms. </LI> <LI> Umbelliferone inhibits total serum levels of IgE, Ig<SUB>G1</SUB>, and Ig<SUB>G2a</SUB> in DNCB/DFE-induced mouse model. </LI> <LI> Umbelliferone regulates MAPK, NF-κB, and STAT1 signaling pathways. </LI> <LI> Umbelliferone reduces pro-inflammatory cytokines and chemokines in vitro and in vivo. </LI> </UL> </P> <P><B>Graphical abstract</B></P> <P>[DISPLAY OMISSION]</P>
