Background: The current treatments of acute myocardial infarct(AMI) Include noninvasive method using thrombolytics and invasive methods such as primary percutaneous transluminal coronary angioplasty(PTCA) and coronary artery bypass graft(CABG)surgery. Although there are many studies comparing the effectiveness of noninvasive and invasive methods, when large clinical centers, 20% of totar hospitals, were excluded, most middle-sized hospitals lacked personnels and facilities for the invasive methods. Thus they opted for the noninvasive methods. Therefore, in this study, the clinical characteristics of AMI patients and the results of thrombolytic & conservative treatment were observed. Method: 137 patients with acute myocardial infarct, who visited KonKuk University Medical Center, ChoongJu Hospital during Sept. 1990 to Sept. 1999 were analysed retrospectively using medical records. Result: The sexual compositions of patients were 63.5% male, and 36.5% female. The mean age for male patients were 56±12.9, and for female patients 68.7±9.6 (p<0.05). The mean age for female patients was significantly older than male patients. The patients in the thrombolytic treatment group had mortality rate of 6.25% which is lower than that of the conservative treatment group at 12% (p>0.05). Conclusion: Although in our study, small number of acute myocardial infarct patients caused the statistical insignificance, rapid revascularization by thrombolytic therapy within 6 hours of onset of symptoms improved mortality rate and early ambulation. And we had good results on AMI with thrombolytic agent in ChungJu including near rural area as primary emergency hospital. Therefore a prospective research with greater number of subjects is needed to develop better treatments for AMI.

Walter Byers, the NCAA Executive Director from 1951 to 1987, coined the term 'student-athlete' in 1973. This phrase has since become widely recognized on college campuses and within society, and implies dual and separate role of being both a student and an athlete. As the term implies, these individuals attend college for two main reason: to make progress towards a college degree and to participate in intercollegiate athletics. The purpose of this study was to investigate factors influencing role conflict on personal attributes, athletic performance and role salience among collegiate student-athletes. The sample was drawn from 821 student-athletes who involved in intercollegiate athletics at the university located in Seoul and Kyunggido and enrolled in Korea Sports Council. They were selected by the method of stratified cluster random sampling. A survey was undertaken from 2003, using the self-administration method. All of questionnaires were personally delivered to the respondents, who immediately filled them out. t-test, one-way ANOVA, multiple regression were used to test and analysis the proposed model in the study. The findings of this study were as follow: 1. Female athletes shows greater cognitive and empirical status role conflict and load conflict, cognitive self role conflict, and empirical student-athlete role conflict than male athletes, three years athletes shows greater cognitive and empirical student-athlete role conflict than any other years athletes, and athletes with high level of life shows cognitive self role conflict and empirical student-athlete role conflict than any other athletes with love of life. 2. Athletic success influence cognitive self role conflict, and playing career has effect on empirical student-athlete role conflict. 3. Relative knowledge related in role of student and athlete has effect on all of cognitive and empirical role conflict, relative time spent in role of student and athlete has effect on cognitive status role conflict, cognitive and empirical load role conflict, and empirical student-athlete role conflict. And relative values of role of student and athlete has effect on cognitive and empirical status role conflict, cognitive and empirical load role conflict, empirical self role conflict and empirical student-athlete role conflict, and relative devotion in role of student and athlete has effect on cognitive self role conflict. status role conflict, load role conflict, and student-athlete role conflict, And satisfaction with student role has effects on cognitive self role conflict, and empirical status role conflict and load role conflict.

This study investigates the fabrication of WC-12Co feedstock powders with weakly locculated slurries by spray drying under various conditions. The morphological defects and flocculation states according to the amount of additives are evaluated to prepare spherical WC-Co feedstock powders with little morphological defects and homogeneous microstructures. The characteristics of feedstock powders, heat treated between 850-1200℃, are analyzed via SEM, EPMA, and mercury porosimetry. The results showed that with the increase in heat treatment temperature the portion of larger pores around 10 μm increased while, that of smaller pores of 1 μm lessened due to the coalescence of WC particles, forming dense feedstock powders with little defects such as hollow or craters. The feedstock heat treated at 1200℃ showed a porosity of 42.2% and a density of 8.28 g/cm^(3) as well as uniform distribution of pores and Co. (Received January 19, 2004)

Helicobacter pylori infection was the cause of chronic gastritis, duodenal ulcer and gastric MALT lymphoma. The eradication rates of H. pylori using antibiotics are around 80%. Lactobacilli have been demonstrated to have in vivo and in vitro inhibitory effects on H. pylori infection. We aimed to evaluate the inhibitory effect of L. lactis CBT-8 and its extract on H. pylori in human stomach. Thirty-five H. pylori-infected volunteers(30-49 yr)were randomized into two groups which were treated with L. lactis CBT-8 and its extract(Group A n=17) or milk containing L. lactis CBT-8(Group B, n=18). They underwent 13C-urea breath tests before and after treatment. The DOB30 of group A(n=14) was decreased 41.0% after treatment(26.0±4.9 before, 15.3±2.1 after treatment)(p<0.05). the DOB30 of group B(n=13) was decreased 22.3% after treatment(22.0±2.2 before, 17.1±1.7 after treatment)(p<0.05). In conclusion, L. lactis CBT-8 was effective in suppressing H. pylori infection in human stomach.

Background: The purpose of this study was to document the incidence and clinical characteristics of patients with tuberculosis (TB) in combat and auxiliary police, living in a group, in Korea where the incidence rate of active TB in a general population is higher than in Western countries. Materials and Methods:We retrospectively reviewed the medical records of all tuberculosis patients diagnosed at National Police Hospital from January 2002 through December 2004. Results:In 2002-2004, a total of 156 cases of tuberculosis were identified with the mean (Standard deviation) age of 20.6 (±1.0) years. Of these, 134 (85.9%) patients were registered as new cases, 11 (7.1%) as relapse, 2 (1.3%) as failure, 5 (3.1%) as treatment-after-default cases whereas 4 (2.6 %) patients were not included in any categories. Average annual new TB rate and smear-positive TB rate were 86.5/10^(5) and 17.4/10^(5) person-years, respectively. In 12 of 31 smear-positive cases, time from onset of symptoms to diagnosis was more than 30 days. Two multidrug-resistance TB cases were identified and two suspected outbreak episodes of TB had occurred during 3 years. Conclusion:There was no statistically significant difference in the incidence rate of new cases of TB between the general population aged 20 to 29 years and combat and auxiliary police in Korea. 배경 : 국내 결핵의 발생은 감소 추세에 있으나 여전히 후진국형 발생양상을 보이고 있다. 특히 집단생활을 하는 젊은이들에서 발생하는 결핵의 유행이 간헐적으로 알려지고 있어 우려를 낳고 있다. 이에 저자들은 최근 전경대원의 결핵 발병 양상에 대해 알아보고자 본 연구를 시행하였다. 재료 및 방법 : 2002년 1월부터 2004년 12월까지 3년간 경찰병원에서 결핵 진료를 받은 전경대원의 의무기록을 후향적으로 분석하여 연도별 결핵 신환발생률, 도말양성결핵 신환율, 진단 지연, 집단발병, 다제내성결핵을 조사하였다. 결과 : 연도별 결핵 신환자 수(10만명당 발생추정치)는 2002년 50명(83.6명), 2003년 42명(83.7명), 2004년 42명(93.5명)이었고 도말양성 폐결핵 신환자 수는 2002년 10명(16.7명), 2003년 11명(21.9명), 2004년 6명(13.4명)이었다. 3년간 도말양성 폐결핵 환자는 31명이 있었고 그 중 12명은 호흡기 증상 발생 30일이 지나서 진단을 받았다. 다제내성 결핵은 2명이 있었으며 결핵의 집단발병이 의심되는 사례는 2차례 있었다. 결론 : 전경대원과 20-29세 연령군 일반인의 결핵 신환발생률, 도말양성 폐결핵 발생률의 통계적으로 유의한 차이는 없었다.

In 2018 2nd semester, 134 students who were attending the ‘A Day of Busan’ were asked to take this survey. Among them, 78 students were from Busan. This paper analyzed these 78 students. According to the respondents' grades, 52.6% of the respondents were in the first grade, slightly more than half, and the second was 33.3%. It can be seen that the 'A Day of Busan' course are mainly in interested in lower grades. According to the year of birth of the respondents, the birth rate in 1999 was 43.6% of the total, including one missing value. In this questionnaire, we surveyed and analyzed the religion of the students, the parent's home, the typical food of Busan, representative places in Busan, and the personality, strengths and weaknesses of Busan people. We also surveyed students' lives, for example, the number of participating in Pusan International Film Festival, the number of visits to professional baseball games, the number of overseas trips, using mobile phones time per day, the number of close friends, sleeping hours. Also we surveyed the population size of Busan. The proportion of students who replied that population size is less than the actual population of 3.45 million in Busan was similar to that of students who replied that it is more. 2018년도 2학기 ‘부산의 하루’ 수강생 가운데 부산출신 학생 78명을 대상으로 분석을 하였다. 응답자의 학년별 구성을 보면 1학년이 52.6%로 절반을 조금 넘고, 그 다음은 2학년으로 33.3%이었다. ‘부산의 하루’ 과목은 주로 저학년이 수강하는 것을 알 수 있다. 응답자의 출생연도를 보면 1999년 출생자가 결측값 1명을 포함한 전체에서 43.6%를 점하여 가장 높은 비율을 보였다. 응답학생 78명의 종교를 보면 무교가 61.5%로 압도적인 비중을 점하고 있다. 그 다음으로 불교가 20.5%, 개신교가 12.8%, 가톨릭이 3.8% 그리고 기타종교가 1.3%였다. 아버지의 고향은 부산이 53.8%로 절반을 넘으며, 그 다음은 경남으로 24.4%였다. 부산과 경남을 합하면 78.2%로 절대적인 비중을 점하고 있다. 어머니의 고향은 부산이 56.4%, 경남이 11.5%로 부산과 경남을 합하면 67.9%였다. 부산의 대표음식으로는 돼지국밥이 36.2%, 21.2%의 어묵, 15.7%의 밀면, 8.7%의 씨앗호떡, 7.4%의 생선회 순이었다. 타지역에서 오는 친구들에게 보여주고 싶은 곳으로는 광안리가 17.9%, 해운대로 13.1%, 서면으로 10.3였다. 그 다음으로는 롯데야구 6.1%, 광안리불꽃놀이 5.3%, 센텀시티 5.1%, 광안대교 4.9% 순으로 나타나 주로 광안리와 해운대 그리고 서면 쪽으로 쏠리는 경향이 나타났다. 부산에서 새로 생기면 좋은 것에 대한 설문에서는 놀이공원이 13.3%, 워터파크10.8%, 공원 8.7%, 체육관 8.2%, 수목원과 박물관이 각각 5.8%로 나타나 학생들은 놀이시설을 가장 원하고 있었으며 그 다음으로 공원과 체육관을 선호하였다. 부산사람들의 성격에서 좋은 점이 무엇인가에 대해서는 ‘의리있다’가 17.8%로 가장 많았고, 나쁜 성격은 32.5%의 압도적인 비율이 성격이 ‘급하다’로 나타났다. 즐겨마시는 음료에는 커피가 33.3%로 가장 높았고, 그 다음은 26.9%의 콜라였다. 주중 술 마시는 횟수에 대한 설문에는 ‘전혀 마시지 않는다’는 학생이 38.5%로 약 40%에 해당하는 학생이 전혀 술을 마시지 않는 것으로 나타났다. 부산국제영화제에 참여한 횟수, 부산에서 열린 프로야구 경기에 참여한 경험, 해외 여행 횟수에 대한 설문에 대해서는 각각 전체의 64.1%, 35.9%, 33.3%의 학생들이 한번도 없는 것으로 나타났다. 하루 휴대전화 사용시간의 평균은 271분, 친한 친구수의 평균은 13명, 수면시간은 평균은 6.8시간, 한달 용돈은 평균 35만원이었다. 부산의 인구가 얼마나 되겠는가 하는 설문에 대한 응답은 매우 다양하였는데, 2만명에서부터 3,800만명까지 넓은 범위에 걸쳐 분포하였다. 그런데 부산의 실제인구 345만명 선보다 적다고 응답한 학생의 비율이 약 절반이었고 나머지 절반은 그보다 많다고 응답하였다.

In this study, as it is said that housing planning can be completed in correlation with major living space, they should recognize the characteristic of furniture use as well as various activities of life as well as various activities of life which are carried omit at home. In this study, the results of each research are summarized as follows. First, diverse activities of life focused on personal lives took places in An-bang. The type of furniture use was composed of standing-oriented type, both standing and sitting and continuous sitting type. When it comes to the preference of the use of furniture, most people preferred to use beds and sofas, they also wanted to diminish An-bang and expand a living room. Second, focused on the pattern of furniture use according to the characteristic of each dweller, the younger, and the more educated, the more they used An-bang as a main space for the husband and wife and they referred to use in a standing-oriented furniture. They also wanted to expand a living room instead of curtailing An-bang in the use of space. Third, when 1 studied main activities of life according to the type of furniture use, there weren't any family activities of life at An-bang in case of standing-oriented type families. There were a few activities of life in case of continuous sitting type and both the standing and sitting type families, but it scarcely happened. Regardless of the type of furniture, people preferred to expand the living room instead of diminishing An-bang. Fourth, the age of housewives turned out to influence the type of the use of furniture, so 1 could come to a conclusion that younger Housewives preferred to buy a standing-oriented furniture, there wasn't any difference in a living room.

Objectives : Patients with organic brain lesion can produce unique slow waves (delta and theta) in the EEG. Basic assumption of this study was that the low resolution electro magnetic tomography (LORETA), an inverse source localization program, can provide functional images representing increased slow wave activity in these patients compared to normal subjects. Methods : The current study was performed by 18 channels digital EEG for 10 patients whose organic deficit have been Visually confirmed by CT or MRI. The source images of slow wave (1-7 Hz) frequency were produced by LORETA-key program. Results : We found that in eight out of ten subjects, LORETA successfully found out the source regions which were very closely matched to their original brain lesions. However in two subjects whose organic brain lesions were too small (<1cm) and located out of gray matter, we failed to find any increased slow wave activity compared with normal control. Conclusion : We can conclude that LORETA could be a useful method to provide functional imaging in patients with gray matter deficits in their brain. Its usefulness and limitations were discussed.

An Ultra-Low-Power Super Regeneration Oscillator-Based Transceiver With 177-<tex> $\mu$</tex> W Leakage-Compensated PLL and Automatic Quench Waveform Generator

Hyung-Gu Park,Juri Lee,Jeong-a Jang,Jae-Hyeong Jang,Dong-Soo Lee,HongJin Kim,Seong Joong Kim,Sang-Gug Lee,Kang-Yoon Lee IEEE 2013 IEEE transactions on microwave theory and techniqu Vol.61 No.9

<P>An ultra-low-power super regeneration oscillator (SRO) transceiver with a 177- μW ultra-low-power phase-locked loop (PLL) and automatic quench waveform generator (QWG) is presented. In order to decrease the PLL power consumption, the leakage current is measured at the VCO control voltage node, and the control voltage is compensated by the digital part. As a result, the frequency can be maintained near 2.37 GHz after the PLL is turned off. An automatic QWG circuit that can search for the critical current of the SRO automatically is proposed in order to mitigate the process, voltage, temperature variations of the conventional QWG. This chip is implemented using 90-nm CMOS technology. The die area of the full transceiver is 3 mm × 4 mm and that of the PLL is 0.4 mm × 0.9 mm. The leakage compensation and high-Q voltage-controlled oscillator (VCO) approach results in a frequency offset of 70 kHz and fluctuation of ±75 kHz (the maximum frequency error is 145 kHz at 60 ppm). The phase noise of the VCO output at 2.37 GHz is -103.5 dBc/Hz at 1-MHz offset. The average power consumption of the PLL is 177 μW from a 1.2-V supply voltage.</P>
