박규리 ( Gyu Ri Park ),안정신 ( Jeong Shin An ) 한국가족관계학회 2016 한국가족관계학회지 Vol.20 No.4
Objectives: The purpose of this study was to explore the moderating effect of stress coping styles on the relationships between loss experiences and depression of the men and women elderly. Method: The subjects of the study were 116 men and 156 women aged over 60 years. For the data analysis, frequency, Cronbach`s α. Pearson`s correlation coefficients, and multiple regression were used. Results: The main results were as follows: First, elderly men reported higher role loss experience, relation loss experience, and problem-focused coping styles than elderly women. Also elderly women reported higher bereavement experience than elderly men. Second, there were main effects of health loss experience, economy loss experience, role loss experience, relation loss experience, problem-focused coping style, and emotion-focused coping style on depression of elderly men and women. Third, problem-focused coping styles moderated the relationships between physical health loss experience, economy loss experience, role loss experience and depression in the elderly men group. Last, social support-seeks coping styles moderated the relationships between economy loss experience and depression in the elderly women group. Conclusions: These results were discussed in terms of educational programs related stress coping strategies for the elderly.
1920년~1945년까지의 동아일보 광고를 통해 본 여성의 건강과 질병
박규리(Gyu-Ri Park),백규환(Kyu-Hwan Baek),정지훈(Ji-Hun Jung),이상재(Sang-Jae Lee) 한국의사학회 2015 한국의사학회지 Vol.28 No.2
In this study, we investigated advertisements in Dong-a newspaper about gynecological drugs between 1920 and 1945 and analyzed the awareness of women’s health and disease during the Japanese Colonial Rule. The advertisements included leukorrhea, oligomenorrhea, dysmenorrhea, feeling of cold, sterility, hysteria, and sexually transmitted infection and identified inattentive menstruation, improper intercourse, poor pre- and post-natal care as the cause for illness. This study includes the following limitations; it only analysed advertisements from Dong-a newspaper, and most of the drugs were manufactured in Japan and might not accurately reflect the health and disease of Korean women. Suggested future studies may include analysis of institute magazine and Japanese news advertisements during this period.

Since the 21st century, strategical cooperation has rapidly been increased. This paper examines the concepts of collaboration and its types through analysis of cases in the fashion industry. Collaboration of the fashion industry is divided into collaboration between companies in the same line of business and in the different line of business. In more detail, both companies in the same field and companies in the different field can be classified into brands, artists from other fields and celebrities. The successful marketing collaboration can be made in strategic regarding brand awareness and identity. Keywords : 디자인, 영역, 콜레보레이션, 마케팅 Design, Area, Collaboration, Marketing
시금치 nitrate reductase cDNA 클로닝 및 염기서열 분석

Suppression of nitrate accumulation in spinach and lettuce through foliar application of chitosan formula containing micronutrients is increase the assinilatory activity, nitrate content could be reduced. For this, NR cDNA was cloned from the isolated mRNAs of spinach using reverse transcriptase - PCR. Nucleotide squence of cloned spinach NR cDNA showed highly deduced amino acid sequence identity(71~78%)with other known plant NR genes. Only two nucleotide-base differences were observed in the cloned NR cDNA compared with that of the published spinach NR cDNA.

Suppression of nitrate accumulation in vegetables through foliar application of micronutrients was investigated. Spinach and lettuce were grown in pots under greenhouse condition. Micronutrient solutions containing Cu, Mn, Mo, and Zn were used; chitosan was added into one and the other contained chitosan oligomers. The micronutrient solutions were sprayed on the leaves at 3 and 4 weeks after transplanting of 20-day-old seedlings. Plants were harvested at 5-weeks after transplanting. Yield, contents of chlorophyll, Brix value, micronutrient, and nitrate, and nitrate reductase activity were measured. Fresh weights of lettuce and spinach were significantly increased by the foliar application of micronutrients. Contents of chlorophyll and micronutrients were higher in micronutrient-treated plants, while those of nitrate were reduced by about 10 and 14-23% in lettuce and spinach, respectively. Compared to the control plants, nitrate reductase activity was higher in plants treated with micronutrients. Results of this study indicate the effect of micronutrients on the suppression of nitrate accumulation was relatively small in comparison to the contents of nitrate in leaves of spinach and lettuce. To maximize the effect, nutrient composition in solution, application time, and frequency should be further examined, taking into consideration nitrogen level in soil and other environmental factors including light condition.

<P>We propose a methodology for the formation of silver (Ag) nanoparticle monolayer as charge trapping layer of nonvolatile memory thin-film transistor using an indium-gallium-zinc oxide semiconductor channel layer. Atomic-layer-deposited Al2O3-amine treatment Ag configuration were employed as tunneling/charge-trap layers, respectively. The memory devices showed wide memory window of 8.0 V, when the gate voltage was swept from -20 to 20 V. The high on/off current ratios of 5.81 x 10(5) and 1.29 x 10(3) could be obtained for the memory device, when the program pulse duration was reduced to 1 mu s and 5 ns, respectively. The Ag nanoparticle monolayer could be prepared by using the amine-functionalized Al2O3 layer. The areal density of Ag nanoparticle was controlled by modulating the Ag ratio in polystyrene (PS) mixture and optimized at Ag: PS ratio of 5: 5. (C) 2016 The Electrochemical Society.

ZnO(산화아연)와 rGO(환원 흑연산화물, reduced graphite oxide)로 구성된 복합체를 제조하여 중저온 영역(300-500 ℃)에서 H₂S(황화수소) 흡착실험을 수행하였다. rGO에 붙어있는 수산화기, 에폭시기, 그리고 카르복실기와 같은 산소를 포함하는 관능기들이 H₂S흡착에 미치는 영향을 조사하기 위해서 다양한 특성분석(TGA, XRD, FT-IR, SEM, 그리고 XPS)을 실시하였다. GO(흑연산화물, graphite oxide)를 rGO로 환원시키기 위해서 마이크로파 조사법을 사용하였다. 마이크로파 조사법에 의한 환원공정에서는 온화한 환원분위기를 조성하여 rGO 표면에 상당량의 산소 관능기들이 남아있는 것을 확인하였다. 이러한 관능기들은 나노 크기의 ZnO가 2D rGO 표면에 균일하게 부착되도록 유도하여 고온 영역에서도 ZnO의 응집 및 소결이 일어나는 것을 방지하는 효과가 있다. 이로 인해 ZnO/rGO 복합체는 순수한 ZnO와 비교하여 3.5배 정도의 흡착량을 보여주었다. Zinc oxide (ZnO) and reduced graphite oxide (rGO) composites were synthesized and tested as adsorbents for the hydrogen sulfide (H₂S) adsorption at mid-to-high (300 to 500 ℃) temperatures. In order to investigate the critical roles of oxygen containing functional groups, such as hydroxyl, epoxy and carboxyl groups, attached on rGO surface for the H₂S adsorption, various characterization methods (TGA, XRD, FT-IR, SEM and XPS) were conducted. For the reduction process for graphite oxide (GO) to rGO, a microwave irradiation method was used, and it provided a mild reduction environment which can remain substantial amount of oxygen functional groups on rGO surface. Those functional groups were anchoring and holding nano-sized ZnO onto the 2D rGO surface; and it prevented the aggregation effect on the ZnO particles even at high temperature ranges. Therefore, the H₂S adsorption capacity had been increased about 3.5 times than the pure ZnO.
