In this paper we investigate and analyze the variation of secondary school student's like and dislike the school mathematics lesson. First, we investigate the reason that why students dislike mathematics in the class and we search the point of time when the students dislike mathematics in the class. Next, we investigate and analyze the variation of student's inclination to the school mathematics lesson. In this research we try the followings. 1) We analyze the variation of each level school, student's inclination to the school mathematics class, 2) We analyze the variation of student's inclination to the mathematics for each place where the school located. 3) We analyze and compare between the inclination to the mathematics lesson and to each level school. 4) We analyze and compare between the inclination to the mathematics lesson and to each factors of student's inclination From these investigation and analysis, we have the following conclusion . (1) The student's inclination to the mathematics is depend on the teacher's teaching method and on the fact that how can the mathematics lesson be composed easily. (2) The student's response was seen in the same type from the inquiry about the inclination to the mathematics lesson in the school of Seoul and small country town. This is a passing phase caused by the educational environment in Seoul and the small country town's schools is better than that of the big city or medium city. (3) The student group of the human knowledge in the general high school show the negative response for the inclination to the matheirlatics lessen compare to that of the student group of natural science in the general high school. (4) In the middle school, about half of the students dislike mathematics But such dislike rate of mathematics increased in the high school. (5) Teachers must take into consideration to the student in the first grade high school mathematics course To do this, teachers make adapt the curriculum easily for the student and must teach the mathematics to the students who can take interest in the mathematics.

Fungus such as Candida albicans is a normal flora that is frequently found in the oral cavity, gastrointestinal tract, genitourinary tract, vaginal mucosa in a normal person. However, candida can cause opportunistic infection in an immune compromised host. Candidiasis has broad spectrum of disease from mucocutaneous infection to invasive or disseminated infection. But, it is rarely reported that candida is associaed with gastrointestinal tract disease in a healthy adult. The case of gastric ulcer associated with candida particularly in a health adult is reported with relevant literature.

Wernicke encephalopathy is an acute neurologic disorder attributable to thiamine (vitamin B1) deficiency. We report the case of a 61-year-old female patient who presented Wernicke encephalopathy after surgery for pancreatic head cancer. From the ninth postoperative day, she had suffered from nausea and vomiting and had difficulties ingesting food, she was given total parenteral nutrition (TPN), but lacked adequate vitamin (thiamine) supplementation. After 28 days, she developed ataxia, ophthalmoplegia, and mental confusion. The magnetic resonance image showed pathologic changes in the medial thalamus,periaqueductal gray matter, medulla and mamillary bodies. The blood level of thiamine was very low. After intravenous and oral supplementation of thiamine (200 mg/day), consciousness was soon normalized and neurologic symptoms have gradually been improving. Nausea and vomiting disappeared after administration of a low dose of mirtazapine (7.5 mg/day). We emphasize the importance of thiamine supplementation to the patients who suffer from vomiting which hinders them from taking food and who require prolonged TPN.

The objective of this research was to develop the adsorbent for heavy metals by activating the bark sample. Barks from pine tree with diameters of 2~4 mm were activated in the muffle furnace under a high relative humidity condition at temperatures of 600~900℃. The removal efficiency of the activated bark (ACTBARK) for Cu and Cd was temperature dependent showing the order of 900℃ > 800℃ > 700℃ > 600℃. The critical temperature was considered to be 900℃ to become an efficient adsorbent for Cu and Cd. The bark samples activated at temperatures lower than 700℃ showed a less removal efficiency than the crude bark The ACTBARK activated at 900℃ removed more Cu and Cd from solution than the commercial activated carbon and charcoal. The ACTBARK (activated at 900℃) adsorbed all of the Cu and Cd in solution with concentrations less than 150 mg/L. The selectivity of the ACTBARK was in the order of Cu>Zn>Ni>Pb>Fe>Cd>Mn.

원작 계열 <金英哲傳>의 발견과 그 자료적 가치

양승민,박재연 한국고소설학회 2004 古小說 硏究 Vol.18 No.-

그동안 학계에 알려진 <金英哲傳> 이본으로는 洪世泰(1653~1725)의 『柳下集』에 수록된 것과 단국대 나손문고 소장본(국문본) 등 2종이 있다. 그리고 『유하집』에 이 작품이 수록돼 있다 보니 자연히 그 작자를 홍세태로 간주해 왔다. 그러나 『유하집』에 전하는 『讓金英哲遺事』라는 시의 幷序로 미루어, 그 문집에 실린 <김영철전>은 홍세태에 순수 창작이 아니라 기존의 「김영철유사」라는 것을 토대로 기술했을 가능성이 높았던 것이 사실이다. 그런 가운데 최근 우리는 『유하집』 수록본과 크게 다른 한문필사본 한종을 새롭게 발견하였다. 이 필사본은 『유하집』 수록본보다 무려 5배나 긴 분량으로 이본 대조 결과 <김영철전> 원작 계열의 한 이본이었다. 『유하집』 수록본은 어떤 선행 이본을 대폭 축약한 것으로, 홍세태가 언급한 그 「김영철유사」라는 자료는 이 필사본과 거의 동일한 양태의 <김영철전>을 가리키는 것으로 보인다. 또한 일명 '김철전'이라는 국문본도 이 필사본과 거의 동일한 어떤 한문본을 번역한 것이었다. 따라서 이 원작 계열 필사본은 연구 가치가 대단히 높다. 이제 우리는 이를 새로운 연구 텍스트로 삼아야 할 것이다. KimYoungChulJeon(金英哲傳) is an unidentified novel written in Chinese language created around the late 17th century. This novel portrays the tragedy of the war that took place in East Asia at the time. The comprehensive scope of this novel includes the general joys and sorrows of the populace of the time that encountered the East Asian war as well as a commoner Kim Young-Chul's life story and his family's tragic life. Until very recently, KimYoungChulJeon has known to be written by Hong Se-Tae(洪世泰: 1653~1725). It is because the novel is collected in Hong Se-Tae's 『YuHaJib(柳下集)』. But another version of KimYoungChulJeon that is quite different from the one collected in 『YuHaJib』 has recently been discovered. This newly found version contains 19,000 words, five times longer that the one found in 『YuHaJib』 that barely contains 3,800 words. This thesis investigates the textual value of the recently discovered version in comparison with the previously known versions. The results of the study can be summarized as follows: First, the recently discovered version is a version of the original series of KimYoungChulJeon. The one collected in 『YuHaJib』 is nothing more than the abridged version of a preceded unidentified version that closely resembles this version of the original series. Second the so-called KimChulJeon(김철전) written in Korean is the translated version from a version written in Chinese that closely resembles this version of the original series. Third, the newly discovered version of the original series contains the superb literary work that you can experience from the one collected in 『YuHaJib』. Therefore, its value for study is priceless. Both versions stem from similar frames of narratives, but when it comes to details, the most vital component for the genre of novel, the difference is immense. Now that the original KimYoungChulJeon has been finally discovered, we should treat it as the valuable text for the further study.

심장 이식 환자에서 발생한 Cryptococcus neoformans에 의한 뇌막염 2예 : The report of two cases

박재형,이윤정,강수진,정영훈,장진석,정준원,최상호,김순종,김양수,김재중 대한화학요법학회 2001 대한화학요법학회지 Vol.19 No.3

최근 장기 이식과 관련된 면역억제제의 사용 빈도의 증가 및 후천성면역결핍증 환자의 증가 등으로 인해 기회감염이 증가되고 있으며, C. neoformans에 의한 감염도 증가되고 있다. 저자들은 심장이식 후 6개월이상 지난 환자에서 발생한 크립토코쿠스 뇌막염 2예를 경험하였는데, 한 예의 경우는 거대세포 바이러스 감염과 함께 C. neoformans의 전신적 파급성 감염의 형태로 나타났었고, 폐에 A. fermigatus에 의한 감염이 같이 병발된 경우였다. 이들은 모두 경미한 증상만을 호소하였고, 뇌척수액 검사를 통해 진단받았으며 liposomal amphotericin B와 경구용 fluconazole을 사용하여 완치되었기에 문헌고찰과 함께 보고하는 바이다. Cryptococcal meningitis is a subacute or chronic mycotic infection caused by Cryptococcus neoformans and it is a second most common central nervous system (CNS) infection in organ transplant patients. The recent rise in incidence of the disease can be attributable to the wide use of immunosuppressive agents in organ transplant patients, the advent of acquired immunodeficiency syndrome (AIDS) patients and increased use of chemotherapeutic agents. We report two cases of cryptococcal meningitis after cardiac transplantation. Their symptoms were not typical and neurologic examination was nonfocal. One patient had disseminated cryptococcal infection and invasive pulmonary aspergillosis, it might be assodated with cytomegalovirus infection. They were diagnosed by cryptococcus latex agglutinin test and culture study with cerebrospinal fluid and treated with liposomal amphotericin B and oral fluconazole without any neurologic defects.

포도상구균의 약제 내성 및 β-lactamase의 생산에 관하여

양재윤,박상욱,이용진,조규봉,이연태 단국대학교 신소재기술연구소 1994 신소재 Vol.4 No.-

항균제의 오남용으로 내성균의 출혈빈도가 매우 높아져 임상가에서는 환자치료에 어려움이 적지 않다. 특히 많은 균종중에서 병원감염의 문제가 되고 있고 포도상구균에 대한 내성빈도는 환자치료에 중요하다고 판단된다. 따라서, 1992년 12월부터 1993년 2월 사이에 서울대 병원에 내원(來院)한 환자로부터 총 108주의 포도상구균을 분양 받아 항균제 내성검사를 실시하였고 황색포도상구균의 경우는 β-lactamase 생산유무 확인 및 methicillin에 대한 MIC 농도를 비교하였으며, methicillin에 대하여 각기 다른 MIC농도를 갖는 균종에 대한 substrate 분해능 검사를 실시하여 다음과 같은 결론을 얻었다 (1). 항균제 내성검사를 실시한 108주의 포도상구균은 penicillin에 가장 높은 내성을 나타냈다. 황색포도상 구균의 경우는 97%, 표피포도상 구균의 경우 100%, coagulase 음성포도상구균의 경우 95.7%로 나타났다 (2). vancomycin의 경우는 전 균주가 감수성을 나타냈다 (3). methicillin에 대한 내성율은 41.4%로 나타났다. 이 내성균주들은 10가지 검사 항생제중 최고 9가지에 대한 항균제 내성을 나타내어 다약제 내성임을 알 수 있었다 (4). β-lactamase 생산 실험에서는 58균주의 황색포도상 구균중 53주가 양성을 나타내어 91.4%의 결과를 얻었다. β-lactamase 생산균주와 methicillin에 대한 내성균주가 반드시 일치하지는 않았다 (5). Spectrophotometric assay에서는 내성이 높은 균주와 낮은 균주간에 β-lactamase에 의한 substrate 분해능이 서로 유사하게 나와 황색포도상 구균의 methicililin에 대한 내성 획득은 β-lactamase 뿐만이 아닌 penicillin binding protein(PBP)의 구조적 변화로 인한 내성획득도 시사함을 알 수 있다. One hundred and eight Staphylococcus aureus strains were isolated from patients of Seoul National University Hospital from December 1992 to Feburary 1993. All strains were tested for their sensitivities against antibiotics. β-lactamse producing test was also performed in order to know the relationship between the methicillin resistance and β-lactamase production. Its activity was determined by direct spectrophotometric method. Initial velocities of hydrolysis of the antibiotics were monitored at wavelength 323 nm which corresponded to maximal change in absorbance between the unhydrolyzed substrate and the hydrolyzed product. The results are summarized as follows: 1. In antibiotics sensitivity test of 108 isolated strains of Staphylococcus, they showed hightest resistance to penicillin but all of tested strains were susceptible to vancomycin. 2. 41.4% of them showed resistance to methicillin. 3. All methicillin resistant strains were found to be multi-drug resistant, from 3 to 9 antibiotics. 4. 91.4%(53 out of 58) produced β-lactamase, β-lactamase producing strains did not always coincide with the methicillin resistant strains. 5. β-lactamase activities were similar among staphylococus strains, irrespective of their methicillin resistance.

박양재 京畿專門大學 2001 京畿專門大學 論文集 Vol.- No.29

In this paper, a single voltage frequency synthesizer with high frequency, fast acquisition time and low power operation is designed. The designed circuit was composed of phase frequency detector, charge pump, loop filter, VCO and prescaer circuits. The designed frequency synthesizer is simulated in a standard 0.35μm CMOS N-Well double-poly four-metal technology with a single 3.3V supply voltage. Simulation results illustrate a locking time of 3.5μs, a power dissipation of 79mW at 1GHz operating frequency with 125MHz of input frequency. Also, Could find the fact that the designed VCO, when the input voltage limits of voltage frequency is 0.4V-2.8V, operating in the frequency broadband of 250MHz-1GHz. This results in fast acquisition time due to the high gain of VCO and a state operation due to a wide input voltage range. Designed frequency synthesizer, welch consuming of low power, operating as a high speed on the high frequency and having a wide operating frequency in 3.3V Power supply, is able to be used in the GSM terminal and mobile station. Also this is expected that could be used of circuit for clock synchronization within high efficiency microprocessor of 1GHz.
