  • This study was conducted to estimate the heritabilities of height and stem diameter growth in 5- and 6-year-old Pinus koraiensis. Estimates of individual tree and family heritability for height growth were $h^2_I=0.40$, $h^2_F=0.77$ in 5-year-old and $h^2_I=0.57$, $h^2_F=0.89$ in 6-year-old, respectively. Heritabilities for diameter growth were estimated as $h^2_I=0.16$, $h^2_F=0.53$ and $h^2_I=0.26$, $h^2_F=072$ in 5-and 6-year-old seedlings.

  • This study aims to define the phylogenetic relationship within Korean Pinus L. and to find the molecular markers which resolve the phylogenetic relationship in genus Pinus. cpDNA atpF-H and psbA-trnH regions were used as molecular markers. We performed the molecular phylogenetic study on 17 taxa of Pinus in Korea. The combined analyses of two gene loci showed that Korean Pinus was a monophyletic group supported by 100% BP. According to the results of separate analyses, psbA-trnH region seems to work better resolving power to clarify the phylogenetic ambiguity in Korean Pinus than those of atpF-H region. Also, we tried to checked the value and resolution of two chloroplast DNA loci on phylogenetic implications.

  • Effect of Pluronic F-68, a nonionic surfactant, on the extracellular production of hGM-CSF in transgenic Nicotiαna tabacum cell suspension culture was investigated. The addition of 5 g/L Pluronic F-68 did not affect the cell growth but increased the extracellular production of hGM-CSF by two-fold. This may be due to the enhanced permeability of the cell membrane by the interaction between the Pluronic F-68 and the cell membrane.

  • Background: The high incidence of prostate cancer as the most common malignancy in males in many countries raises the question of developing reliable detection tests. The prostate specific antigen (PSA) test is the most widely used for screening for prostate cancer; however, its low specificity elevates the number of unnecessarily biopsies. Serum human kallikrein-2 (hK2) is considered as a promising marker, and especially its ratio to fPSA, for predicting the presence of malignancy to select the best choice referring to biopsy or surveillance. In this study, we investigated the role of hK2 and its combinations with other markers to discriminate prostate cancer from benign diseases in Syrian patients. Materials and Methods: In this prospective oriented cross-sectional cohort study, serum samples were collected from patients referred to many Hospitals in Damascus, Syria, between May 2011 and March 2012, and diagnosed with biopsy proven benign prostate hyperplasia (BPH) or prostate cancer (PCa). Serum was analyzed for hK2, PSA and fPSA, and the ratios of fPSA/PSA and hK2/fPSA were calculated. Results: We found that mean hK2/fPSA ratios were significantly higher (P=0.01) in prostate cancer patients than in the BPH or control groups. Also the ratio hk2/fPSA gave the largest area under the curve (AUC:0.96) which was significantly larger than for fPSA/PSA (AUC:0.41) indicative of higher specificity. Conclusions: Our results demonstrate that the ratio of hK2/fPSA might be superior to the use of fPSA/PSA alone. The hK2 could be shown to enhance the early detection of prostate cancer; especially the ratio hK2/fPSA improves specificity and hence may reduce the number of negative biopsies.

  • 유리를 기판으로 하는 superstrate pin 비정질 태양전지에서 전면투명전도막(TCO)과 p-layer의 계면이 태양전지의 효율을 내는데 가장 큰 기여를 한다. 전면투명전도막(TCO)으로 현재 일반적으로 사용되는 ZnO:Al는 $SnO_2:F$ 보다 전기,광학적으로 우수하고, 안개율(Haze)높으며, 수소 플라즈마에서의 안정성이 높은 특정을 갖고 있다. 그래서 박막 태양전지 특성향상에 매우 유리하나, 태양전지로 제조했을 때, $SnO_2:F$보다 충진율(Fill factor:F.F)과 V_{\infty}$ 가 감소한다는 단점을 가지고 있다. 본 실험실에서는 $SnO_2:F$의 F.F가 72%이 나온 반면 ZnO:Al의 F.F은 68%에 그쳤다. 이들 원인을 분석하기 위해 TCO/p-layer의 전기적 특성을 알아 본 결과, $SnO_2:F$보다 ZnO:Al의 직렬저항이 높게 측정되었다. 이러한 결과를 바탕으로 p-layer 에 R={$H_2/SiH_4$}=25로 변화, p ${\mu$}c$-Si:H/p a-SiC:H 로 p-layer 이중 증착, p-layer의 boron doping 농도를 증가시키는 실험을 하였다. 직렬저항이 가장 낮았던 p ${\mu$}c$-Si:H/p a-SiC:H 로 p-layer 이중 증착에서 Voc는 0.95V F.F는 70% 이상이 나왔다. 이들 각 p층의 $E_a$(Activation Energy)를 구해본 결과, ${\mu$}c$-Si:H의 Ea 가 가장 낮은 것을 관찰 할 수 있었다.

  • We have studied $CuF_{2}.2H_{2}O$ using $^{1}H$ and $^{19}F$ pulsed nuclear magnetic resonance at 30 MHz. From the data of lineshapes, the spin-lattice relaxation times ($T_1$) and the spin echo decay times, lattice dynamics in the structure is investigated. $T_1$ data from both $^{1}H$ and $^{19}F$ NMR indicate that spin-lattice relaxation is dominated by the paramagnetic ion centers at the Cu sites. The lineshapes at room temperature appear to be strongly affected by exchange narrowing and motional narrowing.

  • Objectives The purpose of this study is to investigate the characteristics of Ryodoraku Score in the children who visited department of pediatrics, hospital of Korean medicine with allergic rhinitis as the chief complaint. Methods Subjects were 80 children with allergic rhinitis. We calculated the average Ryodoraku Score (RS, ${\mu}A$), and compared the average of each meridian system. And we classified the children by several groups (depending on age, additional allergic disease), and accomplished a comparative analysis. Results 1. The average of Ryodoraku Score in 80 children was $76.36{\pm}22.72$. 2. The figure of H3 (心), H5 (三焦), F1 (脾), F2 (肝), F3 (腎), F4 (膀胱), F5 (三焦), F6 (胃) had significant statistical differences compared to the total average. 3. Comparing the group having only allergic rhinitis to group having allergic rhinitis and other allergic disease, showed significant statistical difference in H2 (心包), H3 (心). 4. Analyzed by age, there's a significant statistical difference in F1 (脾), F4 (膀胱). Conclusion We found that H5 (三焦), F1 (脾), F4 (膀胱) showed significant statistical difference in Ryodoraku Score, and F1 (脾) had the highest relevance. The research indicate meaningful difference depending on age, additional allergic disease.

  • Let $\mathcal{F}(B)$ be the Fresnel class on an abstract Wiener space (B, H, ${\omega}$) which consists of functionals F of the form : $$F(x)={\int}_H\;{\exp}\{i(h,x)^{\sim}\}df(h),\;x{\in}B$$ where $({\cdot}{\cdot})^{\sim}$ is a stochastic inner product between H and B, and $f$ is in $\mathcal{M}(H)$, the space of all complex-valued countably additive Borel measures on H. We introduce the concepts of an $L_p$ analytic Fourier-Feynman transform ($1{\leq}p{\leq}2$) and a convolution product on $\mathcal{F}(B)$ and verify the existence of the $L_p$ analytic Fourier-Feynman transforms for functionls in $\mathcal{F}(B)$. Moreover, we verify that the Fresnel class $\mathcal{F}(B)$ is closed under the $L_p$ analytic Fourier-Feynman transform and the convolution product, respectively. And we investigate some interesting properties for the $n$-repeated $L_p$ analytic Fourier-Feynman transform on $\mathcal{F}(B)$. Finally, we show that several results in [9] come from our results in Section 3.

  • In following addition of 0.3, -0.6, 0.8, 1.0 and 5 weight percent MgSiF66H2O studies have been made of the setting and hardening characteristics of ordinary portland cement. MgSiF66H2O retarded the setting time of ordinary portland cement and extended the induction pariod of the hydration. In ordinary portland cement the setting characteristics were drastically altered especially at high MgSiF66H2O contents. Evidence was also obtained by the formation of a KSiF6 which was very fine particle. The results wee as follows. 1. Slump was slightly decreased when MgSiF66H2O added. 2. Setting time was retarded depending on the amount of retarding agent 2 to 8 hours 3. Compressive strength was almost same or some increased in comparision with opc. 4. When MgSiF66H2O was added to cement paste K2SiF6 were formed It was fine-sized distributed uniformly in cement grain and caused retardation of cement setting.
