In recent years, gonorrhea has been pandemic and remains one of the most common STDs in the world, especially in developing countries. For the detection of a more effective therapeutic regimen and assessing the prevalence of Penicillinase Producing Neisseria gonorrhoeae(PPNG), we have been trying to study the patients who have visited the Venereal Disease Clinic of Choong-Ku Public Health Center in Seoul since 1980 by menas of the chromogenic cephalosporin method. In 1998, 93 strians of N. genorrhoeae were isolated, among which 60(64.5%) were PPNG. The prevalence of PPNG in Seoul, which had been decreased to 39% in 1996 after a peak of 74.3% in 1993, is increased to 64.5% in 1998.

Backgrounds and Objectives: Vascular dementia is a group of dementing disoders arising from various stroke syndrome. Among these. subcortical ischemic vascular dementia (SIVD) is regarded as a relatively distinct clinical entity. However, MRI patterns of SIVD are not homogenous. In some patients, lacunes are dominant, and in others, subcortical white matter changes are. This study was designed to compare risk factor profiles between SIVD with and without multiple lacunes. Methods: We divided 47 subjects (22 males, mean age. 68 years) recruited from VADAPET (Multicenter Trial For Evaluation Of The Changes In the PET Images Of Subcortical Vascular Dementia Patient) study into two groups one with more than 5 lacunes in deep gray matter (lacune group) and the other with 5 or less(non-lacune group) Clinical characteristics and laboratory findings of two groups were compared. Results: Nineteen of 47 patients (40%) belonged to the lacune group. The lacune and non-lacune groups d d not differ in the following variables: age, hypertension, diabetes mellitus, hyperlipidemia heart disease, history of stroke or TIA, history of trauma or major surgery, family history of hypertension stroke, or dementia, age at diagnosis of dementia, body mass index, white blood cell count, ESR, CRP, fibrinogen, hemoglobin A1C, total cholesterol. LDL cholesterol creatinine, proteinuria, glucosuria, and microhematuria. However, male sex, smoking alcohol. hemoglobin, and HDL cholesterol were possibly associated more with lacune group SIVD than with non-lacune group (p<0 1) Multivariate analyses revealed that smoking, hemoglobin, and HDL cholesterol were independent predictors of SIVD with multiple lacunes Conclusion: Our study suggests that SIVD with multiple lacunes may be significantly different in smoking habits hemoglobin, and HDL cholesterol from SIVD without multiple lacunes.

This study focuses on reestablishing martial arts and sports education based on existing educational capabilities in Korean martial arts education to facilitate the localization of Korean culture around the world. Furthermore, the study intends to globalize our own martial arts and apply Yongmoo-do practices to different guard situations, which were originally developed on a great ambition to enhance the position of Korean martial arts in the 21st century as the beginning of new millennium. Guard or escort exists for just a moment which implies accidental emergency. Upon any occurrence of such emergency, the success of guard duty depends on how much rapidly and safely clients can be protected. Therefore, a bodyguard or escort who performs guard duty could face a variety of accidental emergencies so that they must be usually trained with proper martial arts in various way. Yongmoo-do is designed to enable bodyguards to safely deal with unexpected accidents by practical martial skills such as strike, kick, throws(mechigi), snap, neck wring and other skills using weapon. In addition, Yongmoo-do also allows guards to raise their defense capability and survivability against accidental threatening attacks from any suspicious criminal. As described above, it is noted that Yongmoo-do has high applicability enough to meet both safety and self-defense requirements. Thus, it is expected that Yongmnoo-do practices will facilitate trainees to master its theories and phased basic skills so that they can be trained in scheduled and formulated ways based on countermeasures and guard/escort techniques against any occurrence of emergency. Moreover, they will be likely to feel more actuality through an approach of guard martial art according to harmful elements under the simulated guard formation by different situations.

Public utility industries including the electric utility industry are facing a new stream of privatization, competition with the private sector and deregulation The necessity to solve now and in the future power supply and demand problems has been increasing through the sophisticated generation expansion plan(GEP) approach considering not only KEPCO's supply-side resources but also outside resources such as non-utility generation(NUG), demand-side management(DSM) Under the environmental situation in the current electric utility industry, a new approach is needed to acquire multiple resources competitively This study presents the development of a modified electric generation expansion analysis system(EGEAS) model with avolded cost based on the existing EGEAS model, which is a dynamic program to develope an optimal generation expansion plan for the electric utility We are trying to find optimal GEP in Korea's case using our modified mode, and observe the difference for the level of reliabilities such as the reserve margin(RM), loss of load probability(LOLP) and expected unserved energy percent(EUEP) between the existing EGEAS model and our model in addition, we are trying to calculate avoided cost for NUG resources which is a criterion to evaluate them, and test possibility of connection calculation of avoided cost with GEP implementation using our modified model The results of our case study are as follows First, we were able to find that the generation expansion plan and reliability measures were largely influenced by capacity size and loading status of NUG resources Second, we were able to find that avoided costs, which are criteria to evaluate NUG resources, could be calculated by using our modified EGEAS model with avoided cost We also note that avoided costs were calculated by our model in connection with generation expansion plans

이헌경,김승용,홍원선,민영일,정훈용,김해련,정성애,김석균,심기남,양석균,박의련,조문경 대한소화기내시경학회 1999 Clinical Endoscopy Vol.19 No.3

Background/Aims: Although some authors have suggested that sodium phosphate (NaP) is more effective than polyethylene glycol (PEG) in bowel cleansing, there has been no crossover study proving the superiority of NaP over PEG in bowel cleansing and patients' compliance. The aim of this study was to compare the two solutions for colonoscopy, PEG and NaP, through crossover design with regard to patients' compliance, cleansing ability and side effects. Methods: Thirty patients underwent two separate colonoscopies for colonic polyp(s) with PEG and NaP, respectively. Before and after bowel preparation, blood pressure, body weight, and serum biochemical parameters were measured in all patients. In addition, a detailed questionnaire was used to assess side effects and the patients' preference. The presence of bubbles, types of residual stool, and overall quality of colon cleansing were assessed by one endoscopist blinded to the type of preparation used. In each colonoscopy, two biopsy specimens were taken at rectum. Results: In the NaP group, but not in the PEG group, there were significant changes in several biochemical parameters including sodium (+3.0±3.0 mEq/L), potassium (-0.3±0.3mEq/L), calcium (-0.5±0.5 mg/dL), phosphorus (+3.9±2.2 mg/dL) and osmolarity ( +10.1±9.3 mOsm/kg) after bowel preparation. In addition, the degree of body weight change was greater with NaP (-2.2±2.3 kg) than with PEG (-1.2±2.0 kg) (p=0.06) and the formation of bubbles that disturb luminal observation was more frequently found in the NaP group (p$lt;0.01). There was no difference, however, in the type of residual stool and the overall quality of bowel preparation between the two groups and no significant mucosal change was noted after bowel preparation in both groups. Moreover, PEG was found to be more difficult to take than NaP (p$lt;0.05) and among the 30 patients, 26 (87%) preferred NaP, while only two favored PEG (p$lt;0.01). Conclusions: We conclude that NaP can replace PEG at least in patients with good general condition. Further studies to decrease the incidence of bubbles and to establish subgroups suitable for NaP are needed.

고도로 발달된 컴퓨터 기술은 자료의 급속한 축적을 가져왔다. 이 현상은 “무지의 폭발(ignorance explosion)”이라고 표현하는 것이 오히려 적절할 정도로 이전에 볼 수 없었던 정보폭발 현상을 보여주고 있다. 정보 수집 과정에서 정보의 질보다 양이, 정보의 신뢰도와 타당도보다는 정보전달의 속도가 중요시되고 있다는 것은 미래의 사서활동에 하나의 도전이 되고 있다. 이에 관하여 두 가지의 논의가 있다. 첫째, 기술(technology)과 情報歷(information age)과의 관계이다. 사서들은 정보 수집에 이용되는 방법론에 관심을 가져야 할 것이고, 이 방법론은 정보를 수집할 때 나타나는 가치 판단을 포함하는 것이라야 한다. 둘째, 미래를 위하여 의학사서직이라는 전문직을 마련하는 것이다. 전문직에는 거기에 종사하고 있는 전문적 요원들 각자의 개별적인 노력에 의해서만이 인간에 대한 인식과 인간의 가치에 대한 존엄성이 생겨나게 될 것이다. 지금 까지는 인간적인 측면에서의 조사 연구는 소홀히 다루어온 반면 기술에 초점을 맞춘 평가 연구는 많이 시도되어 왔다. 저자에 의하면 의학 사서직을 위한 총체적인 전문직 모형(total prefessional model)에는 교육, 실무 활동 뿐만 아니라 조사 연구가 마땅히 포함되어야 한다고 했다. NIH(National Institute of Health)가 연구자들에게 제공해 주는 것과 비슷한 형태의 MLM(National Library of Medicine)도 박사과정의 도서관 연구자들에게 도움을 주어야 한다고 강조하고 있다. 국립 도서관협회를 통해서 이용할 수 있는 연방정부의 지원이나 장학금의 형식으로 해서 도서관 연구는 생명력 있고 효과적인 3차원의 전문직 모형이 될 수 있을 것이다. 다시 말해서 사서직에서 3차원의 전문직 모형이란 정보저장과 서비스의 전통적인 개념을 인간적인 측면에서 再정의 하고 그러므로써 다가오는 시대에 의학사서직의 영역에 새로운 타당성을 부여해 주는 것을 의미한다. 지난 10년 동안 의학 사서로서의 우리들의 이미지는 컴퓨터화된 데이터 베이스(data base), 온-라인 검색(on-line retrieval), 그리고 새로운 정보자료 공동 활용 테크놀로지(resource-sharing technologies)의 출현으로 고조되어 왔다. 이러한 발달들이 박수를 받고 있는 반면에 이들 기계화는 인간의 의사 결정 과정과 그것이 정보에 依해서 어떻게 영향을 받는지 등 우리의 행위에서 인간적인 측면을 외면해 왔다. 이러한 문제들은 우리들의 전문직 모임이나 도서관 학교에서 좀처럼 발표된 적이없다.

초고진공 상태에서 p형 Si(111)기판에 Ti을 증착한 후 고진공에서 열처리하여 Ti-실리사이드를 형성시켰으며, Ti-실리사이드의 상전이 및 형성운동학은 2 MeV⁴He? 이온 후방산란과 x-선 회절방법으로 규명하였다. 형성된 TiSi₂는 결정학적으로 C49(ZrSi₂)와 C54 구조의 두 종류로 확인되었다. C49 TiSi₂상은 열처리온도가 700℃이하의 저온에서 형성되었고, 700℃ 이상의 고온에서는 C54 TiSi₂상으로 나타났다. 본 연구에서 확인된 C54 TiSi₂전이온도(??)는 700℃ 였고, TiSi₂형성온도 영역내에서 TiSi₂ 층두께(χ)와 열처리시간(t)의 관계는 저온(700℃ 이하)일 경우 ??이고, 고온(750℃ 이상)에서는 χ=ct+d 의 관계식이 만족됨을 알 수 있었다. 이것은 700℃ 이하에서 TiSi₂ 형성기구가 Si 확산에 의해 제어되며, 750℃ 이상에서는 핵형성 제어에 의하여 계면반응하는 것으로 나타났다. Titanium silicides were prepared by depositing titanium film on p-type Si(111) followed by annealing in ultra high vacuum. The growth kinetics of Ti-silicide has been studied by using ion backscattering spectrometry and x-ray diffractometry. Two crystallographic structures of Ti-silicide were identified the (ZrSi₂)structure and C54. The C49 TiSi₂ phase was formed at low annealing temperature(<700℃),and it transformed to the C54 phase over 700℃. The relation between the thickness of TiSi₂ layer(χ) and the annealing time(t) was ?? when annealing temperature was under 700℃ and χ=ct+d when that was over 750℃. The former implied that the formation of TiSi₂ was controlled by diffusion and the latter by nucleation of at the Ti/Si(111) interface.
