과거 주차공간 부족의 문제를 주차시설을 공급함으로써 해결하려 하였으나, 최근에는 환경적 문제·지속가능한 교통적 측면에서 주차수요를 관리해 나가는 형태로 패러다임이 변화하고 있다. 효율적 주차수요 관리를 위해서는 승용차 이용자의 차량 이용실태, 주차의식 조사 등을 통하여 맞춤형 주차관리 정책 수립이 바람직하고, 불법주차에 미치는 운전자의 심리적 변수가 불법주차행위에 어떠한 영향을 미칠 것인지에 대해 ‘계획된 행동 이론(The theory of planned behavior)’을 활용하여 구조방정식을 구축하였다. 분석 결과 불법주차 근절 의지에는 ‘행동에 대한 태도(Attitude)’가 긍정적인 영향을 미치는 것으로 나타났고, ‘지각된 통제감(Perceived behavioural control)’이 부정적인 영향을 미치는 것으로 나타났다. 특히 ‘행동에 대한 태도(Attitude)’ 보다는 ‘지각된 통제감(Perceived behavioural control)’이 불법주차 근절 의지에 더 큰 영향을 미치는 것을 알 수 있다. 향후 불법주차 근절을 위해서는 운전자 심리적 의지를 제어할 수 있는 규범의식, 즉 불법주차로 인한 타인의 피해 정도를 시각화 혹은 계량화할 수 있는 정책홍보 및 상시 주차단속과 같은 강력한 규제정책이 필요할 것으로 판단된다. To manage the demand for parking, it is desirable to establish a customized parking management policy through vehicle usage and parking awareness surveys, and The theory of planned behavior is used to establish a structural equation. The analysis showed that Attitude has a positive effect on the willingness to eradicate illegal parking, and Perceived behavior control has a negative impact. In particular, it can be seen that Perceived behavior control has a greater impact on the willingness to eradicate illegal parking than Attitude. In order to eradicate illegal parking in the future, it is believed that strong regulatory policies such as standard awareness that can control drivers psychological will, i.e., policy promotion and regular parking crackdown that can visualize or quantify the extent of damage caused by illegal parking.

Jae‑Young Park,Kwangsuk Park,Bosung Seo,Julien O. Fadonougbo,Tae‑Wook Na,Ki Beom Park,Hyeon‑Tae Im,Nong‑Moon Hwang,Hyung‑Ki Park 대한금속·재료학회 2022 METALS AND MATERIALS International Vol.28 No.7

This study examines the insulation coating technology of Fe–Si–Cr powder via selective oxidation annealing, which oxidizeselements selectively by controlling the oxidation potential. The study calculated the oxidation driving force of Fe, Si, andCr, and conducted a thermodynamic analysis of oxidation and reduction conditions according to temperature and oxidationpotential. Based on the results, a selective oxidation annealing was performed in an atmosphere in which Fe is reduced andonly Si and Cr are selectively oxidized. The oxidation potential was controlled through the partial pressure ratio of hydrogenand water vapor. The XPS analysis results confirmed that a Si and Cr complex oxide layer formed on the powder surfaceafter the selective oxidation annealing. Afterward, withstanding voltages were analyzed to evaluate the insulation property. Then, the withstanding voltage of the powder applying the selective oxidation annealing increased significantly comparedto that of the initial powder. Further analysis showed that the powder annealed in an air atmosphere had a significantly lowersaturation magnetic flux density than the initial powder, while the powder applying the selective oxidation annealing hadonly a slightly reduced saturation magnetic flux density.

연구목적 : 본 시험의 목적은 임상시험 시작전에 연구자들을 대상으로 PANSS Workshop을 통하여 PANSS, ESRS에 대한 국내에서의 표준화 작업을 구축하고 새로운 정신병 치료제인 리스페리돈의 효과와 안정성을 재확인하여 리스페리돈 사용에 대한 적정화를 이루는데 있다. 연구방법 : 1996년 4월부터 1996년 9월까지 국내 39개 대학병원 정신과에 입원중인 혹은 증상이 악화되어 입원하는 정신분열병 환자 377명을 대상으로 다시설 개방 연구를 시행하였다. 1주일간의 약물 배설기간을 가진후, 리스페리돈을 8주간 투여하였고, 기준점, 1주, 2주, 4주, 그리고 8주후에 평가되었다. 용량은 제1일에는 리스페리돈 1mg씩 1일 2회, 제2일에는 2mg씩 1일 2회, 제3∼7일에는 3mg씩 1일 2회 투여하였다. 이후 환자의 임상상태에 따라 임의로 증량할 수 있으며, 최대 일일 16mg을 초과하지 않도록 하였다. 추체외로 증상을 조절하기 위한 투약을 허용하였다. 임상증상 및 부작용의 평가는 PANSS(Positive and Negative Syndrome Scale), CGI(Clinical Global Impression) 그리고 ESRS(Extrapyramidal Symptom Rating Scale)을 사용하였다. 연구결과 : 377명중 343명(91%)이 8주간의 연구를 완결하였다. 치료 종결시점인 8주후 PANSS 총점수가 20% 이상 호전된 경우를 약물 반응군으로 정의할때, 약물반응군은 81.3%였다. 리스페리돈에 반응하는 예측인자로는 발병연령, 이전의 입원 횟수, 유병기간이 관련 있었다. 리스페리돈은 1주후부터 PANSS양성, 음성, 및 일반정신병리 점수상에 유의한 호전을 보여 효과가 빨랐다. CGI의 경우도 기준점에 비해 1주후부터 유의한 감소를 나타내었다. ESRS의 경우, 파킨슨 평가점수는 기준점과 비교해 투여 1주, 2주, 4주후 유의하게 증가되었다가 8주후 기준점과 차이가 없었다. Dystonia 평가점수는 1주후만 유의한 증가를 보였으며, dyskinesia 평가점수는 유의한 차이가 없었다. 혈압, 맥박수의 생명징후 및 일반 혈액학 검사, 생화학적 검사, 심전도 검사에서 유의한 변화는 없었다. 결 론 : 이상의 다시설 개방 임상 연구를 통해 리스페리돈은 정신분열병 환자에서 양성증상뿐만 아니라 음성증상 및 전반적인 증상에도 효과적인 것으로 사료된다. 보다 명확한 평가를 위해서는 다른 항정신병약물과의 이중맹검 연구가 필요할 것으로 생각되며, 또한 장기적 치료에 대한 평가도 함께 이루어져야 하겠다. Objective : The purpose of this study was to investigate the efficacy and safety of risperidone in the treatment of Korean schizophrenic patients. Method : This multicenter open study included 377 schizophrenic patients drawn from 39 university hospitals. After a wash-out period of 1 week, the schizophrenic patients were treated with risperidone for 8 weeks and evaluated at 5 points ; at baseline, and 1, 2, 4 and 8 weeks of treatment. The dose was increased from 2mg/day(1mg twice daily) to 6mg/day(3mg twice daily) during the first week and adjusted to a maximum of 16mg/day over the next 7 weeks according to the patient's clinical response. Medication to control extrapyramidal symptoms was permitted. The psychiatric and neurological status of the patients was assessed by PANSS, CGI, and ESRS scales. Results : 343(91%) of 377 patients completed the 8-week trial period. Clinical improvement, as defined by a 20% or more reduction in total PANSS score at end point, was shown by 81.3% of patients. The predictors of response to risperidone were associated older age, shorter duration of illness, fewer previous hospitalization. Risperidone had rapid onset of action ; a significant decrease of the total PANSS and three PANSS factor(positive, negative, general), and CGI was already noticed at the end of first week. For the ESRS, parkinsonism rating scores were significantly increased until week 4 comparing with baseline. Dystonia rating scores were significantly increased until week 1, and dyskinesia rating scores were not significantly changed during the study. Laboratory parameters including vital sign, EKG, hematological, and biochemical values showed no significant changes during the trial. Conclusions : This study suggests that risperidone is generally safe and effective against both the positive and negative symptoms in our group of patients.

Owing to the complexity of the deviated structures and the septal deformities accompanying the external nasal deformities, the complete correction of the deviated nose is regarded as a difficult one. The approach to the nasal bone and osteotomy in classic corrective rhinoplasty is almost blind technique, where the results depends on the feeling by surgeon's hand. To overcome these drawback, endoscopic-assisted corrective rhinoplasty and septoplasty performed for 8 cases of deviated nose between January 1996 and May 1997. Average follow-up period was 10 months. All patients were evaluated by symmetrical nasal pyramid, recurrence of the bony deflection and septal deviation. The postoperative courses were satisfactory in most of cases with few complications. It appears that endoscopic control during corrective rhinoplasty and septoplasty is a big step toward obtaining better results in bony and cartilage resection with extreme precision under monitor control and magnification. This technique is not an open approach but permits one to see more of the nasal skeleton and bony septum what is causing deformity, and the immediate effect of the corrective measures used. The use of endoscope in corrective rhinoplasty will provide expanded field of vision, direct manipulation of lesions, and better aesthetic an6 functional results.

Y??NdxBa₂Cu₃O?? 고온초전도체의 X-선 회절 분석 과 적외선 투과율 측정은 실온에서 수행되었다. 또한 수송임계 전류밀도는 77K에서 측정되었고, 저항은 80~140K 범위의 온도에서 조사되었으며, 시료들은 고상 반응법에 의해서 제조되었다. 한편 x의 양이 변함에 따라서 전이온도 Tc는 88K 근처의 값을 가지며, 거의 x의 양에 따라 변하지 않았다. 적외선 투과율 측정에서 날카로운 peak들은 472.23~618.87㎝?범위에 있었다. 이것은 특이할 정도로의 low-lying plasmalike edge와 낮은 에너지의 전자적인 여기가 존재함을 나타내는 것이다. 수송임계 전류밀도는 22~92 A/㎠ 범위에 있었다. X-ray pellet diffraction and IR transmittance measurements were been carried out at room temperature. Also the transport critical current density and resistivity of high Tc superconducting Y??NdxBa₂Cu₃O?? system were determined at 77K and in the range of 80~140 K. The sample were prepared by solid state recation. As x varied, the superconducting transition temperature Tc near 88K did not depend on x. In the infrared transmittance measurements, several sharp peaks were observed in the range of 472.33~618.87㎝-1. This indicates that unusual low-lying plasmalike edge and low energy electronic excitation exist. The transport critical current densities determined ranged from 22 to 92A/㎠.

박기정,이병욱,박용하 한국미생물생명공학회 ( 구 한국산업미생물학회 ) 1996 한국미생물·생명공학회지 Vol.24 No.1

국내 제놈 프로젝트와 생물학 연구자들을 지원하기 위한 GINet 서버에서 분석 프로그램들을 Web을 통해 사용할 수 있도록 GINet 분석계산용 Web 서버를 구성하였다. 각 분석 프로그램의 구조를 분석하여 필요한 데이타와 옵션의 종류 및 사용 형태를 정리한 후, 사용자가 이들을 입력할 수 있는 입력 form을 HTML로 작성하였다. 입력된 옵션과 데이터는 Web 서버에 전송되는데, 이들을 분석하여 해당 실행 프로그램을 실행한 후 분석 결과를 Web 사용자에게 전송해 주도록 CGI 프로그램들을 작성하였다. 특히 분석 프로그램의 형태를 2가지로 나눠 각 경우 CGI 프로그램을 구현하는 공통적인 절차를 구성하였고, 여기에 각 분석 프로그램마다 개별적으로 다른 부분은 개별적으로 보완하는 방식으로 각 CGI 프로그램을 구현하였다. 현재 이 서버에서 직접 지원하는 분석 프로그램은 사용 빈도가 가장 높은 프로그램들과 자체 개발한 프로그램들을 포함한 것이고, 추후 설치되거나 자체 개발되는 프로그램들의 대부분도 이 계산 Web 서버에서 제공될 수 있도록 시스템이 구성될 것이다. A computation server is needed to provide analysis programs to Korean biologists, especially genome researchers, on GINet. For each analysis program, we implmented an input form with HTML and a CGI program of interface between an input form and an analysis program with C language on GINet computation Web server. We made two construction methods of CGI programs for analysis programs, and implemented all CGI programs based on the methods followd by modifying each CGI program for specific processing of each analysis program. On the server ten programs are available now, which include most frequently used ones and those developed by our team, and most programs which will be ported or developed by our team will be available on the Web server.

Experimental results from the cycle lateral load tests for post-tensioned precast wide beam-column connections were presented. Six exterior beam-column assemblages of half scale were tested in the laboratory. The specimens consist of U-shaped precast wide beams and concrete columns. The continuity at the beam-column joint is achieved with the topping concrete and post-tensioning. The specimens were designed with parameters of the beam-to-column depth ration and the number of tendons within column core. The test results showed that the post-tensioned precast wide beam-column connection satisfied the provisional standard by ACI of acceptance criteria for concrete special moment frames.
