Stress induced cardiomyopathy (SC) is characterized by transient left ventricular (LV) dysfunction in the absence of coronary artery disease. We report on a patient with panhypopituitarism who developed SC resulting from withdrawal of hormonal replacement therapy (HRT). A 52-year-old male visited our hospital for progressively worsening dyspnea. The patient had discontinued HRT 7 days ago, which had been administered for 18 months after transsphenoidal adenomectomy for pituitary macroadenoma. Initial electrocardiogram showed marked sinus bradycardia. Transthoracic echocardiography showed apical ballooning with an LV ejection fraction of 25%. No significant obstructive lesions were observed on coronary angiography. With a clinical diagnosis of SC associated with panhypopituitarism, HRT was restarted, including glucocorticoid and thyroxine, along with standard heart failure management. His LV function had normalized at 2-month follow-up. He remains asymptomatic and administration of beta-blocker and angiotensin converting enzyme inhibitor were discontinued He currently only requires HRT.

The purpose of advanced traffic information system(ATIS) is to help drivers save time and energy in getting to their destinations by providing traffic information through variable message sign(VMS), internet, traffic broadcasting and mobile phones. ATIS does not just provide drivers with benefits in terms of time and energy, but it provides them with psychological benefit as well, i.e., the drivers can relieve their anxiety by getting provided with traffic information. In this study, the efficiency of traffic information system is evaluated and degree of satisfaction of drivers with the system is analyzed by building satisfaction models of various media of traffic information. Each medium has different factors for satisfaction and each factor has different degree of influence, but in general, the efficiency of traffic information in helping drivers choose routes and in providing drivers with peace of mind is considered to have the highest influence on satisfaction of drivers with the system.

2010년 11월 05일부터 11월 29일 중 총 12일간 진천 소재 충북대학교 천문대의 60cm 반사망원경과 ST-8 CCD 카메라를 이용하여 BD And의 BVR CCD 측광 관측을 수행하여 처음으로 BVR 광도 곡선을 완성하였다. 또한, 극심시각 결정을 위한 측광관측이 레몬산 천문대 1m 반사망원경과 충북대학교 천문대의 35cm 망원경으로 수행되었다. 우리의 관측과 SWASP 관측을 통하여 모두 31개의 극심시각을 새로이 결정하였다. 새로운 관측은 이 별의 공전주기가 이전까지 알려진 0.4629일이 아니라 그 두 배인 0.9258일이며, 기산점도 반주기 바뀌어야 함을 보여 준다. BD And의 광도요소를 Min I = HJD 2434962.8602 + 0.d9258054 E으로 새롭게 개정하였다. 이 광도요소로 작성한 우리의 BVR 광도곡선은 제1식과 제2식의 깊이가 거의 비슷하며, 식바깥 부분에 잘 발달된 파형 모양을 보인다. 이는 BD And가 짧은 주기의 RS CVn형 식쌍성임을 나타내는 것이다. 우리의 극심시각을 포함한 총 144개의 극심시각에 대한 (O-C)도를 작성한 결과, BD And의 공전주기가 규칙적으로 변화하는 것을 발견하였다. 이 변화를 보이지 않는 제3천체에 의한 광시간 효과로 가정하여, 궤도이심율이 0.78이며, 9.19년의 주기를 가진 광시간 궤도를 결정하였다.우리의 광도곡선을 2003년 Wilson-Devinney 쌍성 모형으로 분석하여 광도곡선 해를 질량비 q=1.1822, 궤도경사각 i=$86.^{\circ}16$, $T_1$=6358(K), $T_2$=6250(K), $r_1$=1.117(Rsun), $r_2$=1.321(Rsun)와 같이 산출하였다. 식바깥에서 나타나는 파형 모양의 변화는 주성의 표면에 매우 큰 흑점으로 잘 설명되며, BVR 광도곡선에서 각각 전체 광도의 각 6.4%, 8.1%, 9.9%에 해당되는 제3 광도가 검출되었다. 이는 주기연구에서 제안된 제3천체의 존재 가능성을 더 공고히 한다.

Since the completion of the genome project of the nematode C. elegans in 1998, functional genomic approaches have been applied to elucidate the gene and protein networks in this model organism. The recent completion of the whole genome of C. briggsae, a close sister species of C. elegans, now makes it possible to employ the comparative genomic approaches for identifying regulatory mechanisms that are conserved in these species and to make more precise annotation of the predicted genes. RNA interference (RNAi) screenings in C. elegans have been performed to screen the whole genome for the genes whose mutations give rise to specific phenotypes of interest. RNAi screens can also be used to identify genes that act genetically together with a gene of interest. Microarray experiments have been very useful in identifying genes that exhibit co-regulated expression profiles in given genetic or environmental conditions. Proteomic approaches also can be applied to the nematode, just as in other species whose genomes are known. With all these functional genomic tools, genetics will still remain an important tool for gene function studies in the post genome era. New breakthroughs in C. elegans biology, such as establishing a feasible gene knockout method, immortalized cell lines, or identifying viruses that can be used as vectors for introducing exogenous gene constructs into the worms, will augment the usage of this small organism for genome-wide biology.

As genetic research is getting more active, data construction of genes are needed in the field of biology. Therefore, Gene Ontology Consortium has constructed genetic information by OWL, which is Ontology description language published by W3C. However, previous browsers for Gene Ontology only support simple searching mechanisms based on keyword, tree, and graph, but it is not able to search high quality information considering various relationships. In this paper, we suggest browsing technique which integratesvarious searching methods to support researchers who are doing actually experiment in biology field. Also, instead of typing a query, we propose querv generation technique which constructs query while browsing and query translation technique which translate generated query into SeRQL query It is convenient for user and enables user to obtain high quality information. And by this GO Guide browser, it has been shown that the information of Gene Ontology could be used efficiently.

Carbon fiber-reinforced SiC matrix composites have good oxidation resistance and thermal shock resistance. These properties have allowed the composites to be applied to high-temperature structures. In this study, $C_f/SiC$ composites were fabricated via precursor infiltration and pyrolysis (PIP) process, including liquid phase infiltration and chemical vapor curing using cyclohexene. The final $C_f/SiC$ composites, which have gone through the PIP process five times, showed a density of $1.79g/cm^3$, as compared to a density of $0.43g/cm^3$ for pre-densified bare carbon fiber preform. As for the oxidation resistance characteristics, the weight of $C_f/SiC$ composite was maintained at 81% at $1400^{\circ}C$ in air for 6 hours. Chemical vapor curing (CVC) using cyclohexene has shown to be an effective method to achieve high densification, leading to increased oxidation resistance.

Objectives : The aim of this study is to evaluate the safety of acupuncture therapy when applied to patients who are undergoing anticoagulants / antiplatelet medication therapy combined with herbal medicine using a retrospective, case-control study. Methods : 428 charts of patients were reviewed in this study. Odds ratio between case of bleeding-related adverse event and control was calculated as main analysis. Exposures were anticoagulants / antiplatelet medication, Hwalhyeolgeoeo herbal medicine and combination of both drugs. Additionally, odds ratios were calculated according to the severity of bleeding-related adverse events. Results : The results were as following: 1. Analysis of all bleeding-related adverse events showed there was no increased risk of combined therapy compared with other exposures and control group. 2. Analysis of only clinically significant adverse events showed there was no increased risk of combined therapy compared with other exposure and control group. 3. Hwalhyeolgeoeo herbal medicine group showed a tendency of increased risk of bleeding-related adverse events in all analysis but was not statistically significant. Conclusions : The results suggest that Hwalhyeolgeoeo herbal medicine-anticoagulant / antiplatelet medication combined therapy may not increase risk of bleeding-related adverse events in acupuncture therapy. By executing various modules of analysis, it was possible to acquire useful data for possible future studies. Further research is needed to confirm such results.

Kim Su-On(1409~1481) was a editor in King Sejong's times who worked on the publication of "Euibangyoochui(醫方類聚)" and other major publications led by the royal family. This paper will review the works of Kim Su-On based on the medical background of early Joseon Dynasty and the medical book-reading officer system, and also evaluate his contribution to the development of medicine in early Joseon Dynasty, factoring in his life, ideas, and literary talent. By looking at the life of Kim Su-On, we can understand the role of Confucian doctors(儒醫) in the early Joseon Dynasty, how Confucian scholars who were learned in medicine supervised the compilation and correction of "Euibangyoochui(醫方類聚)". Especially, from the poetry of "Sikujip(拭疣集)", contents regarding the proofreading of "Euibangyoochui(醫方類聚)" between Im Won-jun and Kim Su-On shows the publication process of "Euibangyoochui(醫方類聚)" at the reign of King Sungjong. His outstanding achievements are largely due to the medical book-reading officer system implemented around the time "Euibangyoochui (醫方類聚)" was published. The medical book-reading officer system aimed to increase the knowledge of various matters for the civil service bureaucrats, allowing them to become high-ranking officials in the fields of technology. Its another purpose was to compile specialty publications. Many of the civil service bureaucrats who participated in the medical book publications arranged the theoretical basis of medicine and modified experience medicine to a new medical system. The first edition of "Euibangyoochui(醫方類聚)" at King Sejong's reign collected vast medical information into 365 books. Then it was corrected during King Sejo's reign then finally completed and published at King Seongjong's reign. During this period, the experience medicine inherited from Goryeo Dynasty was reestablished into a new form of theoretical interpretation.
