본 연구는 늘어나는 대중교통인접 환승주차장의 범죄위험성으로부터 이용자들의 안전을 위하여 ‘환경설계를 통한 범죄예방(Crime Prevention Through Environment Design: CPTED, 이하: CPTED)"개념을 적용하여, 환경디자인 개선사항을 도출하는 연구이다. 연구의 방법과 범위로는 CPTED이론, 문헌분석, 관련법 및 법규, 관련 전문가그룹을 통하여 1차 정량·정성체크리스트를 설계하여 현장답사 하였으며, 이를 보안하는 2차 정성체크리스트를 설계, 현장답사 하였으며, 현장답사는 대중교통환승 주차장의 유형과 환승형태, 주차장규모, 운영주체등을 고려하여 수도권의 5개 환승주차장을 선정하였다. 설계된 체크리스트를 바탕으로 현장답사 결과 범죄위험성으로부터 환경디자인 개선사항은 5곳 중 1곳을 제외하고 4곳 모두 개선이 필요한 것으로 분석되었다. 분석은 주차지역, 유지관리, 전자보안, 안내표지, 조경, 조명으로 구분하였으며 조사대상지 대부분 범죄위험성으로부터 전자보안에만 의지하는 행태를 가졌으며, 그 또한 요금 징수 등을 주 목적으로 하고 있다. This study applies the concept of Crime Prevention Through Environmental Design (CPTED) and suggests ways to make improvements in environmental design to provide secure facilities for those who use park-and-ride structures which are increasing on a regular basis. First, the authors made a checklist for field examination after consulting related literature and related laws and holding discussion sessions with the experts of the field. After the field investigation with the quantitative and qualitative checklist, another qualitative checklist was developed to supplement the first one. With the second checklist, the authors visited five different park-and-ride structures around the city of Seoul that were diverse in layout, scale, and management system. The result showed that four out of the five sites assessed needed improvements. The analysis was divided into the following areas: location of the structure, maintenance, electronic security, signs, landscaping, and lighting. A popular method of crime prevention at the parking structures was electronic security which was in fact operated mainly to encourage the drivers to pay their parking fees.

In this elderly patients, incidence of pulmonary tuberculosis is very high because of the decreased function of the body immune system and combined diseases. We analysed radiographic findings of 51 patients with pulmonary tuberculosis to compare with the typical findings of reactivation pulmonary tuberculosis in the adult over 60 years old. The typical location of reactivation pulmonary tuberculosis is the apicoposterior segment of the upper lobe and the superior segment of the lower lobe. But in elderly patients of our study, 38cases(76%) showed lesions also in atypical location such as the anterior segment of the upper lobe, the middle lobe, or the basal segments of the lower lobe. Also 36cases(72%) showed multilobar extents, 30cases(59%) showed unusual findings and 26cases(52%) showed multiple cavities and in 19 cases(38%), differential diagnosis with lung cancer was difficult. Especially in patients with diabetes mellitus, involvement of the anterior segment of the upper lobe was significantly high compared with the patients without DM.

Five adults (3 cases of bilateral posterior crossbite, 2 cases of unilateral posterior crossbite) with intermaxillary discrepancy of over 5㎜ due to maxillary transverse deficiency were treated by surgically assisted rapid maxillary expansion (SARME). Bilateral maxillary horizontal osteotomies, osteotomies of pterygomaxillary junction and anterior lateral nasal wall, ans anterior palatal osteotomy were performed in 4 cases, and unilateral osteotomies in 1case, followed by palatal expansion with tooth-borne orthopedic applicance. No significant complication was observed. The mean palatal expansion was 7.2㎜ (5.8∼10.0㎜) in the maxillary first molar region. During the mean follow-up period of 4 years (5 months∼8 years 7 months), no recurrence of crossbite was observed in all cases. The SARME seemed to be a simple, stable, and reliable procedure for achieving a permanent increase of over 5㎜ in skeletal maxillary transverse width of adults.

휘발성유기화합물(VOCs)의 변이원성 검정

박종천,이용탁,송현철,이우범 國立麗水大學校 環境問題硏究所 2004 環境硏究論文集 Vol.6 No.-

The mutagenicity of six kinds of VOCs(benzene, m.p-xylene, chloroform, toluene, methylethylketone, 1,2-dichloroethane) detected in high concentration and frequency in Kwangyang Bay was investigated. VOCs are water-insoluble and volatile. Therefore, when they are tested by the classical Ames test in the assay of mutagenicity, there may be experimental errors. To overcome this limitation, modified Ames test was used to assay mutagenicity of VOCs. By this modified Ames test, we could obtain much more satisfactory results. Even at extremely low concentration(0.0001㎍/㎖). bezene, m,p-xylene, and methylethylketone showed a weak mutagenicity. When S-9 mixture is added in the assay system, all tested VOCs except methylethylketone showed mutagenicity. When Salmonclla typhimurium TA 98 and Salmonella typhimurium TA 100 are exposed to VOCs of high concentration(100㎍/㎖). the number of colony decreased irrespective of the S-9 mixture treatment. It seem to be that the decrement results from the toxic effect of high concentration of VOCs.

In order to investigate the microstructure and mechanical properties on Al–25Cr–5Si (at%) alloy, a mixed powder with pureelements and an alloy powder using a gas atomization process were used. Fine and high purity Al–25Cr–5Si (at%) alloypowder was successfully prepared by gas atomization and densified using a spark plasma sintering (SPS) process. The overallpowder size distribution of the mixed Al, Cr, and Si elemental powders was in the range of 10–15 μm. The atomized Al–Cr–Sialloy powder was fine and spherical in morphology and difficult to be formed by intermetallic formation. Densification wasclearly confirmed at 1000 °C, with almost isolated pores formed, by clear removal of pores between particles, deformationof particles, an increase in the number of contacts, and a change in size between particles. As a result of XRD analysis ofthe sintered compacts, single phase was observed using the mixed powder, but the compact using gas atomization remainedthe alloy phase even at the process temperature. The Vickers hardness of the compacts by mixed powder was observed at59.70 Hv and the compact using gas atomized powders on the temperature 1000 °C of the Vickers hardness increased to702.6 Hv. The compressive yield strength of the compact with mixed powder was 195.24 MPa and the compressive strengthof the compact with gas atomized powder increased to 802.07 MPa. It is considered not to be decomposed by the AlCrSi,Al13Cr4Si4and Al8Cr5phases sintering process, resulting from the improvement of mechanical properties.

Although ureteroscopy(URS) has been used widely to remove ureteral calculi, there is an argument against the belief that anesthesia or admission is needed for URS. We evaluated the experience of URS without anesthesia in female patients. From September 1997 to July 1998, URS was performed in 31 female patients without anesthesia. EHL(Electrohydraulic Lithotripsy) was used in 21 patients with impacted or large stone over 5mm. All patients were given oral antibiotics for 3 days and follow-up KUB was taken to confirm successful removal of the stone one week after the procedure. Successful treatment was defined as complete removal of the stone or residual fragments less than 2mm. Overall success rate was 96.7%(30 cases among 31 cases). All but one patient tolerated with analgesia through the entire procedures. There were only minimal complications such as mild flank pain and hematuria. So, we recommend that non-anesthetic ureteroscopic removal of stone as the first choice for treatment of lower ureteral stones in female based on the minimal morbidity, high success rate and low cost.

돼지 아데노바이러스(PAV-3). 6618주의 EIB region이 包含되어 있는 map unit 4.0에서 9.7까지의 유전자에 대한 1,984 bp의 염기서열을 決定하였으며, 이 結果를 알려진 여러 아데노바이러스 유전자와 비교하여 다음과 같은 결과를 얻었다. 1. PAV-3의 EIB유전자는 10개의 ORF로 구성되어 있으며, 그 중 아데노바이러스의 단백질과 유사성이 있는 것은 ORF1, ORF2 및 ORF3이었다. ORF1은 Ad41의 19kd 와 BAV-2에서의 EIB ORF2에서의 아미노산의 一致率은 각각 32%와 31%이었다. 2. ORF2는 Ad2 55kd protein과 tupaia adenovirus 44kd protein가 각각 34%로 아미노산 一致率이 가장 높았으며, Ad41의 52kd protein. BAV-3의 EIB ORF3에서도 33%의 一致率을 보였다. 3. ORF1은 61-666 uncleotide (606 bp), ORF 2에서는 429-1,850 uncleotide (1,422 bp)의 부위로 각각 202, 474 a.a로 構成되었으며, 예상되는 분자량은 20 kd와 52 kd이었다. 4. ORF3는 hexon-associated pIX유전자로 추정되며 내부에 1개의 polyadenylation signal(ATAAA)이 1938-1942 uncleotide에 위치하였으며, 이 부위는 TATA box (1937-1942 uncleotide)와 중복되어 존재하였다. Porcine adenovirus type 3 (PAV-3) does not cause severe infection in pigs. Adenovirus has been suggestive of live vaccine vector carrying foreign gene. One of insertion regions is delayed early (EIB) region. However, EIB region of PAV-3 has not been molecularly characterized to date. Nucleotide sequence of EIB of PAV-3 was determined. The EIB region was composed of 1,984 bp and located between 4.0 and 9.7 map units. Three potential open reading frames(ORFs) with low level of homology to other adenoviruses and a polyadenylation signal were identified in the rightward direction of genome. The nucleotide and the predicted amino acid sequences of EIB were compared to those of human and animal adenoviruses. One of the three potential ORFs. ORF1 encoded a polypeptide homologous to bovine adenovirus type 2(BAV-2) ORF2 and human adenovirus type 41(Ad41) 19 kd protein. ORF2 encoded a polypeptide homologous to human adenovirus type 2(Ad2) 55 kd protein, bovine adenovirus type 3(BAV-3) ORF3 and porcine adenovirus type 4(PAV-4) ORF2. The predicted protein of ORF1 had homology to those of Ad41 and BAV-2 with 32 and 31% respectively, whereas the deduced protein of ORF2 had homology to those of Ad2. BAV-3 and PAV-4 with 34, 33 and 29%, respectively.
