Background Streptomyces seoulensis has contributed to the discovery and initiation of extensive research into nickel superoxide dismutase (NiSOD), a unique type of superoxide dismutase found in actinomycetes. Still so far, there is no information about whole genome sequence of this strain. Objective To investigate complete genome sequence and perform bioinformatic analyses for genomic functions related with nickel-associated genes. Methods DNA was extracted using the Wizard Genomic DNA Purification Kit then sequenced using a Pacific Biosciences SMRT cell 8Pac V3 DNA Polymerase Binding Kit P6 with the PacBiov2 RSII platform. We assembled the PacBio longreads with the HGAP3 pipeline. Results We obtained complete genome sequence of S. seoulensis, which comprises a 6,339,363 bp linear chromosome. While analyzing the genome to annotate the genomic function, we discovered the nickel-associated genes. We observed that the sodN gene encoding for NiSOD is located adjacent to the sodX gene, which encodes for the nickel-type superoxide dismutase maturation protease. In addition, several nickel-associated genes and gene clusters-nickel-responsive regulator, nickel uptake transporter, nickel–iron [NiFe]-hydrogenase and other putative genes were also detected. Strain specific genes were discovered through a comparative analysis of S. coelicolor and S. griseus. Further bioinformatic analyses revealed that this strain encodes at least 22 putative biosynthetic gene clusters, thereby implying that S. seoulensis has the potential to produce novel bioactive compounds. Conclusion We annotated the genome and determined nickel-associated genes and gene clusters and discovered biosynthetic gene clusters for secondary metabolites implying that S. seoulensis produces novel types of bioactive compounds.

Background : Pneumocytitis cainii pneumonia (PCP) can occur in immunocompromised hosts especially such as AIDS or cancer patients. Although recent research had focused on PCP in AIDS patients, few studies have described the clinical presentations of PCP in recipients of stem cell transplantation (SCT). We evaluated the clinical manifestations of PCP in SCT patients admitted at St. Mary's hospital, Seoul, Korea. Methods : The medical records of 17 PCP patients undergoing SCT between Feb. 1998 and Feb. 2000 were reviewed. The diagnosis of PCP was confirmed through the demonstration of Pneumocytitis cainii via either cytology of brochoalveolar lavage (BAL) or histological technique of lung biopsy. CMV disease and CMV infection were confirmed by BAL culture and antigenemia respectively . Results : Seventeen patients were all recipients of allogeneic SCT and 7 of 17 patients were performed non-sibling SCT. Patients presented with symptoms including brief period (4 ∼23 days) of fever (76%), dyspnea (70%), cough (64%), and signs such as rare(58.8%), Sixteen patients (94%) had been receiving immunosuppressive agent such as cyclosporine A (64%) or Fk506 (35%) without PCP prophylaxis. Eleven patients (64%) were treated with corticosteroid with mean dose of 16 mg/day prednisolone and mean duration of 4.6 months after post-SCT period. Twelve patients were co-infected with CMV. Another co-infected miCroorganisms were Pseudomonas aeruginosa, Mycobacterium tuberculosis, herpes simplex virus, parainfluenza virus, Average duration of treatment with trimethoprim-sulfamethoxazole (TMP/SMX) was 21 ±9 days. Four patients died, and three of them were related with PCP. Conclusion : PCP developed frequently in patients who were taking immunosuppressive drug due to graft versus host disease or were not taking TMP/SMX prophylaxis. High risk patients showing fever, cough, or dyspnea should be considered to take early bronchoscopic intervention for detection of PCP. When treat for PCP, it also be considered to the possibility of coinfection such as CMV. (Korean J Infect Dis 33:273∼279, 2001)

Objectives: This study aims to examine if a garbage dumping site has real and negative influence on the quality of life (QOL) for the nearby residents. The net effects of the residential distance from the garbage dumping site and from the garbage truck route were investigated for five domains of the QOL. Methods: Two hundred fifty seven Shin-dong Myeon residents, Chun-cheon Si, participated in a self-administrated survey. The Shin-dong Myeon garbage dumping site began operating in 1996. ANCOV A with generalized linear models and multiple regression analysis were performed. Results: Descriptive analyses show that a residence nearby a garbage dumping site is negatively associated with the physical and environmental domains of the QOL. The residential distance from the garbage truck route does not exert any significant effect on various domains of QOL, except for the environmental domain. On the multivariate analysis, the residents living near the garbage dumping site tended to have a significantly negative QOL in the physical and environmental domains. However, the distance from the garbage truck route did not show a significant nor substantial effect on the QOL. The demographic and socioeconomic control variables are associated with a number of the QOL domains, and their patterns are consistent with the general expectations. Conclusions: The results indicated that a garbage dumping site is considered to be an environmental hazard among the nearby residents according to the lower scores on the physical and environmental domains of the QOL. The findings from this study provide comprehensive understanding on the residents' QOL, and they may help politicians and policy makers make decisions for appropriate interventions.

We have examined the comparative efficacy of small doses of intravenous urapidil and labetalol in blunting hemodynamic response to endotracheal intubation and surgical incision in 30 patients without cardiovascular diseases. After intravenous urapidil 0.2 mg/kg or labetalol 0.2 mg/kg anesthesia was induced with thiopental 5mg/kg. Endotracheal intubation was facilitated by vecuronium 0.15 mg/kg with priming principle and anesthesia was maintained with enflurane and nitrous oxide in oxygen. Systolic, diastolic and mean arterial pressure and heart rate were measured before administration of the drugs, 5 minute after administration, just prior to endotracheal intubation and 1, 3, 5, 10 minute after intubatin. Also the peak blood pressures and heart rate within 10 minutes after surgical incision were measured. Endotracheal intubation and surgical stimulation were associated with significant increases in blood pressures and heart rate in both urapidil and labetalol group. Comparison of the changes in systolic, diastolic, and mean artrial pressures and heart rate between urapidil and labetalol group showed no significant difference except peak systolic pressure after surgical incision. It is concluded that the pressor response to endotracheal intubation and surgical stimulation are not influenced significantly by urapidil 0.2 mg/kg or labetalol 0.2 mg/kg. However, urapidil and labetalol preloading may be similarly effective in the blunting of the increases in blood pressures with larger doses of the durgs during anesthetic induction.

The excessive initial corrosion rate of Mg is a critical limitation in the clinical application of biodegradable Mg implantsbecause the device loses its fi xation strength before the fractured bone heals. This study suggests a new approach to overcomethis hurdle by accelerating tissue regeneration instead of delaying the implant biodegradation. As angiogenesis is anessential process in early bone regeneration, a Mg implant coated with electrospun nanofi bers containing nitric oxide (NO),which physiologically promotes angiogenesis, is designed. The integrated device enables adjustable amounts of NO to bestored on the NO donor-conjugated nanofi ber coating, stably delivered, and released to the fractured bone tissue near theimplanted sites. An in vitro corrosion test reveals no adverse eff ect of the released NO on the corrosion behavior of the Mgimplant. Simultaneously, the optimal concentration level of NO released from the implant signifi cantly enhances tube networkformation of human umbilical vein endothelial cells without any cytotoxicity problem. This indicates that angiogenesis canbe accelerated by combining NO-releasing nanofi bers with a Mg implant. With its proven feasibility, the proposed approachcould be a novel solution for the initial stability problem of biodegradable Mg implants, leading to successful bone fi xation.

As modern people's interest in health grows, wearable healthcare-related technologies that can collect biometric information and receive health-related services regardless of time and place are developing. This paper proposes the healthcare system based on voice recognition function. Unlike conventional wearable healthcare systems, the proposed system provides real-time telemedicine and diagnosis and the direct connection with doctors is possible through it. And almost all functions of the application in it are operated with voice commands to lower user access barriers. Because it deals with personal information including medical information, encryption algorithms have been applied between all data movements. Finally, the healthcare system proposed in this paper is expected to increase convenience in health care and reduce the medical gap.

오늘날의 '칼날, 글귀, 길가, 물결, 물고기, 밀가루, 발톱, 솔방울, 활시위, 뭇사람, 이튿날, 사흗날, 일기, 바닷가, 바닷물, 송진, 햇빛'과 같은 어휘는 각각 중세국어 시기의 '?Fㄴㆍㄹㅎ, ?G句, ?zㄱㆍㅅ, ?逵? ?逵慈? ?Bㄱㆍㄹㆍ, ?M톱, ??방올, ?시울, ?O사ㄹㆍㅁ, 이?날, 사ㅇㆍㄽ날, ??氣運, 바ㄹㆍㄽㄱㆍㅅ, 바ㄹㆍㄽ믈, ??진, ??빛' 등에 대응되는데, 모두 '-ㄹ]Noun+ㅅ+Noun'의 동일한 內的 構造를 갖는다. 본고에서는 오늘날 상이한 구조의 어휘들이지만, 기원적으로는 동일한 구조의 어휘들을 相同構造의 어휘라고 부른다. 결과적으로 字素形을 중심으로 볼 때, '-ㄹ]Noun+ㅅ+Noun'이었던 어형들은 크게 세 가지 유형으로 심리 어휘부(mental lexicon)에 전승·저장되었는데, 'ㄹ' 유지형인 '칼날, 글구/글귀, 길가, 물결, 물고기, 밀가루, 발톱, 솔방울, 활시위' 등, 'ㄹ' 탈락형인 '뭇사람; 이튿날, 사흗날' 등, 그리고 대체형인 '일기(日氣), 바닷가, 바닷물, 송진(松津), 햇빛' 등이 그것이다. 즉 이들은 원래 상동구조였으나 전승·저장되는 과정에서 심리 어휘부 속의 어근 어휘부나 접사 어휘부의 각기 다른 간섭의 결과로 서로 상이한 내적 구조 유형에 속하게 된 것이다. 본고에서는 현대국어 시기의 어형을 바탕으로 나눈 이 세 가지 유형에 따라 어근 어휘부와 접사 어휘부가 이들의 변화에 각각 어떻게 간섭하였는지를 밝힌다. This paper aims to take a close look at '-ㄹ]Noun+ㅅ+Noun' compounds that appered upon the scene of history variously. For example, '?Fㄴㆍㄹㅎ, ?G句, ?zㄱㆍㅅ, ?逵? ?逵慈? ?Bㄱㆍㄹㆍ, ?M톱, ??방올, ?시울, ?O사ㄹㆍㅁ, 이?날, 사ㅇㆍㄽ날, ??氣運, 바ㄹㆍㄽㄱㆍㅅ, 바ㄹㆍㄽ믈, ??진, ??빛'. As far as '-ㄹ]Noun+ㅅ+Noun' compounds is concerned, we denominate lexemes of the etymologically same structure lexemes of "the homologous structure(相同構造)". From the standpoint of a grapheme, '-ㄹ]Noun+ㅅ+Noun' compounds are divided into three groups, which have been transmitted to the mental lexicon. For example, '칼날(the blade of a knife), 글구/글귀(passage), 길가(roadside), '물결(wave), 물고기(fish), 밀가루(wheat flour), 발톱(toenail), 솔방울(pine cone), 활시위(bowstring)' etc belong to 'ㄹ' maintenance group, '뭇사람(crowd); 이튿날(next day), 사흗날(third day)' etc belong to 'ㄹ' omission group, and '일기(weather), 바닷가(beach), 바닷물(sea water), 송진(pine resin), 햇빛(sunshine)' etc belong to alternation group. Because the root lexicon and the affix lexicon of the mental lexicon have interfered in '-ㄹ]Noun+ㅅ+Noun' compounds. Accordingly they have been belonged to the unlike internal structures.

본 연구의 목적은 일정한 논리적 절차를 거쳐서 객관적인 전과정평가의 우선순위를 선정하기 위한 일반적인 방법론의 개발이다. 우선 전과정평가 대상이 되는 제품(산업군)의 우선순위를 평가하기 위해서 제품의 환경성과 관련된 환경규제, 국내외 전과정평가 수행사례, 유해물질 등을 평가항목으로 설정하였다. 설정된 평가항목들에 대한 자료조사 및 분석을 통하여 세분화한 데이터베이스를 생성하였으며, 또한 학계 및 산업계의 의견을 반영하기 위해 전과정평가 전문가 및 산업계 관계자들을 대상으로 설문조사를 실시하였다. 설문조사결과를 바탕으로 각각의 평가항목 및 세부평가항목의 가중치를 부여하였고, 각 평가항목별로 점수를 설정하였다. 본 연구에서 개발한 방법론은 우선순위를 비교해야하는 제품(산업군)들이 각각의 평가항목에서 설정해놓은 해당 점수를 부여받게 된다. 부여받은 각 평가항목의 점수들을 모두 합산하면 평가대상이 되는 제품(산업군)에 대해 하나의 우선순위 평가 점수를 갖게 된다. 이와 같은 과정으로 방법론이 구축되었으며, 사례연구를 통하여 방법론의 타당성을 검증하였다. 이렇게 산출된 우선순위 평가점수를 평가하고자하는 제품(산업군)들과 비교하여 높은 점수를 갖는 제품(산업군)이 전과정평가를 먼저 실시하는 것이 바람직하다는 결론을 얻을 수 있다. The purpose of this study is to develop a general method to decide the priority of LCA application through a logical procedure. First of all, evaluation categories were developed to decide priority of subject products(industrial groups). The evaluation categories consist of environment regulations related to subject product, LCA case studies, hazardous substances, etc. The subdivided database was constructed through researching and analyzing information about the selected evaluation categories. In addition, a questionnaire was conducted to reflect the opinions from academic and industrial circles. Based on the result of the questionnaire, each evaluation category and sub-evaluation category were weighed differently, and certain points were assigned to them. According to the method developed in this study, comparing industrial groups or products for prioriting will have its total score that is a sum of points assigned to each evaluation category. This results that an industrial group or product having higher score than the others becomes the subject to apply LCA.
