  • Pleural effusion means the inflammation of pleura which has a majority of respiratory disease. The main clinical manifestation is pleural effusional pain, dyspnea, cough, fever, etc. and at present the Tuberculous pleural effusion has the most frequency in which exists exudate in our country. And during studying oriental medical treatment about Tuberculous exudative pleural effusional patient, we found the clinical case about The Combination therapy of Chinese traditional and Western medicine at journal of traditional Chinese Medicine and considered it would be help in oriental medical treatment, so we adjust and report now. This study was performed by analyzing the six papers reported centering around the clinical case of The Combination therapy of Chinese traditional and Western medicine in journal of traditional Chinese Medicine published between 1990-1996. As these papers have no mistakes on diagnosis because it obtained pleurocentesis, tuberculin test positive reaction on choicing clinical case, definite results on X-ray, ultrasound as well as clinical basis, so it considers an apt conclusion. The results were as follows: 1. Western medical treatment uses chemical remedy same with pulmonary tuberculosis, and in case of tubercular pleuritis, it needs thoracic duct pyorrhea, and according to simple exudation also operates therapheutic pleural paracentesis. 2. In case of hydrothorax absorption about tuberculous pleural effusion, prescription of purge the heat accumulated in the lung and eliminate the retention of fluid with powerful purgatives shows considerable effects. 3. The latter period treatment of tuberculous pleural effusion needs Supplement qi and active the collaterals, Nourishing yin and clearing heat in addition to Supporting healthy energy to eliminate evils. 4. In case of curing tuberculous pleural effusion, The Combination therapy of Chinese traditional and Western medicine shows more considerable effect than single western medical treatment in absorption of hydrothorax. 5. In case of curing tuberculous pleural effusion, The Combination therapy of Chinese traditional and Western medicine shows more considerable effect than single western medical treatment in prevention of disease reappearance. 6. In case of curing tuberculous pleural effusion, The Combination therapy of Chinese traditional and Western medicine shows more considerable effect than single western medical treatment in vitality recovery at the latter period of disease.

  • The First stars (Pop.III stars) in the universe are expected to be formed between the recombination era at z - 1100 and the most distant quasar (z - 8). They have never been directly detected due to its faintness so far, but can be observed as a background radiation at around 1${\mu}m$ which is called the Cosmic Near-Infrared Background (CNB). Main part of the CNB is thought to be redshifted Lyman-alpha from gas clouds surrounding the Pop.III stars. Until now, the COBE (COsmic Background Explorer) and the IRTS (Infrared Telescope in Space) observed excess emission over the background due to galaxies. To confirm the COBE and the IRTS results and pursue more observational evidences, we carried out the sounding rocket experiment named the Cosmic Infrared Background ExpeRiment (CIBER). The CIBER is successfully launched on July 10, 2010 at White Sands Missile Range, New Mexico, USA. It consists of three kinds of instruments. We report the results obtained by LRS (Low Resolution Spectrometer) which is developed to fill the uncovered spectrum around 1${\mu}m$. LRS is a refractive telescope of 5.5 cm aperture with spectral resolution of 20 - 30 and wavelength coverage of 0.7 to 2.0${\mu}m$. After subtracting foreground components (zodiacal light, integrated star light and diffuse galactic light) from the sky brightness of observed five fields, there remained significant residual emission (even for the lower limit case) consistent with the IRTS and the COBE results. In addition, there exists a clear gap at 0.7 - 0.8${\mu}m$ in the CNB spectrum over the background due to galaxies according to recent results (Matsuoka et al. 2011; Mattila et al. 2011). The origin of the excess emission could be ascribed to the Pop.III stars with its active era of z = 7 - 10.

  • 현대사회는 고지방의 서구화된 식사, 과도한 스트레스 등으로 비정상적인 혈액응고 및 과다한 혈소판 응집이 증가되고 있으며, 이로 인한 다양한 혈전성 질환 위험성도 증가되고 있다. 본 연구에서는 제주 특용식물인 상동나무(Sageretia thea) 지상부의 항혈전 활성을 평가하기 위해 잎(ST-L), 줄기(ST-B), 열매(ST-F) 에탄올 추출물을 조제하고 이의 항혈전 활성, 인간 적혈구 용혈활성 및 flavonoids·phenolic acids 조성을 검토하였다. ST-B 추출물은 식용으로 이용되고 있는 ST-F 추출물보다 6.7배의 총 폴리페놀 함량을 보였으며, ST-L 추출물은 ST-F 추출물보다 2.7배 높은 총 플라보노이드 함량을 보였다. 혈액응고 저해활성 평가 결과, ST-F 추출물은 aPTT에서만 혈액응고시간 연장이 미약하게 나타났으나, ST-L 및 ST-B 추출물은 기존 항혈전제인 aspirin 및 베리류 및 한방 약재 추출물보다 트롬빈, 프로트롬빈, 응고인자들에 대해 강력한 저해활성을 나타내었다. 혈소판 응집저해 역시 ST-L 및 ST-B 추출물은 aspirin보다 우수한 응집저해 활성을 나타내었으며, 인간 적혈구에 대한 용혈활성은 1 mg/ml 농도까지 전혀 나타나지 않았다. ST-L 및 ST-B 추출물의 phenolic acid 및 flavonoids 분석결과, rutin, isoquercitrin 및 astragalin이 주요 활성물질로 확인되었다. 본 연구결과는 상동나무 잎과 줄기의 강력한 항혈전 활성의 최초 보고이며, 상동나무를 이용한 항혈전제 개발이 가능함을 제시하고 있다. 향후 상동나무에서 처음으로 확인된 isoquercitrin의 항혈전 기전에 대한 연구가 필요하다.

  • 벼는 임성 식물체의 재분화 뿐만 아니라 유전적으로 안정된 형질전환 식물체를 얻을 수 있는 가장 성공적인 단자엽 식물중 하나이다. 그러나 우리나라에서는 아직 유전적으로 안정된 임성 형질전환 벼품종에 대한 보고가 없었다. 본 연구에서 우리나라의 재배종인 낙동벼로부터 임성 형질전환식물체를 얼을 수 있음을 증명하였다. 현탁뱅양세포로부터 분리된 원형질체를 이용하여 PEG로 HPT와 GUS Plasmids늘 함께 형질전환시켰다. 다섯번의 실험을 통하여 hygromycin 저항성 캘러스는 평균 1.73%이였다. 소식물체는 항생제 저항성 캘러스로부터 재분화되었고 식물체 재분화효율은 약 27%이었다. 항생제에 저항성이 있는 캘러스에서 GUS 유전자가 발현되는 캘러스는 평균 35%였다. R0형질전환식물체는 성숙 개화하여 Rl 종자를 생성하였다. Rl 종자와 유모의 해부학적 GUS 활성을 분석하여 CaMV35S 프로모터 의해 GUS 유전자가 적절히 발현되는 것을 확인하였다. 또한 우리는 Rl세대에서 HPT유전자가 멘델 법칙에 따라 유전됨을 확인하였다

  • The aim of this study was to investigate the current state of wife abuse in Seosan and the relationships between wife abuse and the related variables. A total of 132 couples took part in this study. All couples live in Seosan city, range in age from their 20s to 50s and each couple has at least one child. Stratification sampling method was used to select the couples. They were asked to complete self-report questionnaires. Subjects completed a Korean version of the self- esteem scale, marital conflict scale, communication style scale, family history of violence scale, alcohol dringking, and wife abuse scale. In order to examine the current state of wife abuse, such as, frequency, mean, standard deviation and paired t-test, t-test were calculated and analyzed. Next, to identify differences in wife abuse between the upper group and the lower group, t-test was peformed. Finally, to investigate the relative influences of independent variables upon wife-abuse, multiple regression analysis was peformed. All these analyses were conducted using SPSS 10.0 program. The results were as follows; 1) In terms of the current state of wife abuse, there are three main observations. First, $23\%$ of respondents answered that they had beat their spouse or been beaten by their spouse before and after their marriage. Second, compared with physical violence($2{\~}16\%$), other types of violence such as verbal($7{\~}4\%$), emotional($41{\~}64\%$), economical($3{\~}29\%$) and sexual violence($4{\~}38\%$) were reported to occur more often in these relationships. Third, following the abuse most wives tend to tolerate the situation instead of taking an active action like reporting the abuse to police. 2) As for the husbands, subjects that drank a high level of alcohol, blaming and super-reasonable communication style, and family history of violence reported more frequent cases of wife abuse. As for the wives, subjects with high levels of self-esteem, irrelevant communication style, marital conflict, and family history of violence reported having more cases of that abuse. 3) In the case of husbands, alcohol, communication style and family history of violence explained $40\%$ of wife abuse. In the case of wives, marital conflict and family history of violence explained $77\%$ of their experiences with abuse. This study makes the contribution to aims to develop education programs and family therapy relevant to prevent wife abuse and to reconsider the existing laws governing domestic violence in Korea.

  • In a previous paper (Kim et al., 1996a), the immediate 5' -flanking region and coding region of the human UDP-N -acetylglucosamine:-D-mannoside-1,4-Nacetylglucosaminyltransferase III (N-acetylglucosaminyitransferase- III; GnT-III) gene was reported, isolated and analyzed. Herein, we report on amplification of a new 5' -noncoding region of the GnT-III mRNA by single-strand ligation to single-stranded cDNA-PCR (5' -RACE PCR) using poly(A)+ RNA isolated from human fetal liver cells. A cDNA clone was obtained with 5' sequences (96 bp) that diverged seven nucleotides upstream from the ATG (+1) start codon. A concensus splice junction sequence, TCTCCCGCAG, was found immediately 5' to the position where the sequences of the cDNA diverged. The result suggested the presence of an intron in the 5' -noncoding region and that the cDNA was an incompletely reversetranscribed cDNA product derived from an mRNA containing a new noncoding exon. When mRNA expression of GnT-III in various human tissues and cancer cell lines was examined, Northern blot analysis indicated high expression levels of GnT-III in human fetal kidney and brain tissues, as well as for a number of leukemia and lymphoma cancer cell lines. Promoter activities of the 5' -flanking regions of exon 1 and the new noncoding region were measured in a human hepatoma cell line, HepG2, by luciferase assays. The 5'-flanking region of exon 1 was the most active, whilst that of exon 2 was inactive.

  • InSb has received great attentions as a promising candidate for the active layer of infrared photodetectors due to the well matched band gap for the detection of $3{\sim}5\;{\mu}m$ infrared (IR) wavelength and high electron mobility (106 cm2/Vs at 77 K). In the fabrication of InSb photodetectors, passivation step to suppress dark currents is the key process and intensive studies were conducted to deposit the high quality passivation layers on InSb. Silicon dioxide (SiO2), silicon nitride (Si3N4) and anodic oxide have been investigated as passivation layers and SiO2 is generally used in recent InSb detector fabrication technology due to its better interface properties than other candidates. However, even in SiO2, indium oxide and antimony oxide formation at SiO2/InSb interface has been a critical problem and these oxides prevent the further improvement of interface properties. Also, the mechanisms for the formation of interface phases are still not fully understood. In this study, we report the quantitative analysis of indium and antimony oxide formation at SiO2/InSb interface during plasma enhanced chemical vapor deposition at various growth temperatures and subsequent heat treatments. 30 nm-thick SiO2 layers were deposited on InSb at 120, 160, 200, 240 and $300^{\circ}C$, and analyzed by X-ray photoelectron spectroscopy (XPS). With increasing deposition temperature, contents of indium and antimony oxides were also increased due to the enhanced diffusion. In addition, the sample deposited at $120^{\circ}C$ was annealed at $300^{\circ}C$ for 10 and 30 min and the contents of interfacial oxides were analyzed. Compared to as-grown samples, annealed sample showed lower contents of antimony oxide. This result implies that reduction process of antimony oxide to elemental antimony occurred at the interface more actively than as-grown samples.
