Polycyclic aromatic hydrocarbons(PAHs) in sediments of Kwangyang bay on Korea, have been investigated by gas chromatography-mass spectrometery (GC/MS). The average content of total PAHs in all samples was 2,211ppb, and the range was from 36 to 22,699pph. The higher concentrations were found in sediment sampled near Kwangyang iron processing plant, Taeindo. The resulting distributions of PAHs according to the number of aromatic ring and molecular ratios of specific aromatic compounds (phenanthrene, anthracene, fluoranthene and pyrene) have been discussed in terms of sample location, origin of the organic matter. Four, five and six rings of PAHs were mainly found near to Kwangyang iron processing plant, and three and four rings near to Yeosu chemical kombinat. This result typically indicated the local characteristics, depending on the origin of PAHs.

정흥호,박은희,김도수,정호승,노재성 공주대학교 자원재활용신소재지역협력센터 2000 2차년도 센터 사업 성과집 Vol.2000 No.1

Sol-Gel법으로 Aluminum isopropoxide[Al(i-OC3H7)3]와 규산나트륨로 부터 THF로 추출한 규산을 사용하여 mullite 겔 분말 제조시 산염기촉매의 영향에 관하여 XRD, TGA. SEM, 및 BET를 이용하여 연구하였다. 산성촉매로는 염산 (HCl)과 질산(HNO3)을, 염기성촉매로는 암모니아 (NH4OH)를 사용하였다. 촉매에 따른 중량 감소는 HCI=32.6% > HNO3=25.43% > Non=24.0% > NH4OH=22.5% 순서로 나타났다. 입자의 형태는 산성촉매인 경우 구형의 입자를, 염기능촉매의 경우는 구형이 아닌 입자형태를 나타내었다. 1400℃에서 하소한 분말은 촉매의 종류에 관계없이 0.05∼0.1㎛ 크기의 매우 미세한 입자들의 응집체임을 알 수 있었다. 그리고 촉매의 종류에 관계없이 온도가 증가할수록 흡착할 수 있는 세공이 줄어듬을 알 수 있었고, 염기 촉매를 사용하는 경우의 mullite 비표면적 변화가 거의 없는 내열성을 가지고 있었다. Effect of catalysts, which was catalyzed by acid(HCl and HNO3) and base(NH4OH), on characteristics of the mullite powders prepared by sol-gel method was investigatad by XRD, TGA, SEM and BET. As a result, weight loss as a function of catalysts was in order of HCI=32.6% > HNO3=25.43% > Non=24.0% > NH4OH=22.5%. The mullite powder dried at 100℃ appeared spherical shape in acid catalyst and different shape in base catalysts but sintering powder at 1400℃ appeared very fine particle of 0.05~0.1 ㎛ ragardless of catalysts. In all case, the pore quantity, which was capable to adsorption, was decreased with increasing temperature. In base catalyst, no change of special surface area in mullite appeared.

Objects : Many studies have demonstrated greater frequency of soft neurologic signs in patients with schizophrenia than in controls. However, factors associated with chronicity,institutionalization, individual differences and neuroleptic medication make it difficult to interpret these results. We report on our ongoing study of soft neurologic signs and their relationship to neuroleptics and institutionalization in schizophrenia. Methods : Soft neurologic signs were examined with a standardized instrument, Neurological Evaluation Scale- Korean Version(NES-K) in 11 neuroleptic-naive patients with schizophrenia, 17 neuroleptic-treated patients and 14 chronically institutionalized patients. Results : Scores of total items(p<0.05), sensory integration(p<0.05), sequencing of complex motor acts(p<0.05) and others(p<0.01) functional areas of NES-K were significantly different among three groups. There was no difference in the area of motor coordination. Posthoc analysis showed that scores of total items(p<0.005) and sensory integration areas(p<0.01) of NES-K were significantly higher in the institutionalized patients than those of neurolepticnaive group. However scores of sequencing of complex motor act and others categories were not different in the institutionalized and neuroleptic-naive patients. Conclusion : These findings suggested that neuroleptic treatment or chronic institutionalization might partially affect soft neurologic signs, especially sensory integration area, in patients with schizophrenia. However, the soft neurologic signs of motor coordination area could be a biological trait marker of schizophrenia independent of confounding variables.

채정호,차성조,함웅,이규항,이정균 大韓神經精神醫學會 1996 신경정신의학 Vol.35 No.5

한 정신병원에서 강박처치의 적응증, 합병증, 대체법, 감정적 영향, 적당한 처치 시간, 처치의 효능과 필요성등을 병원에 입원 중인 환자들과 직원들에게 설문조사를 하여 양 집단간에 차이가 있는 지를 알아봄으로써 환자들과 직원들간에 있는 강박처치에 대한 지각 차이를 조사하고 나아가 강박처치 시행의 규준을 확립하기 위한 기본 자를 제시하기 위하여 본 연구를 시행하였다. 강박처치의 적응증에 대해서 입원환자들은 대부분의 항목에 대해 부정적으로 보았고 단지 타환자에 대한 신체적 공격에 대해서만 다소 긍정적인 반응을 보인 반면 직원들의 경우 자해, 타환자에 대한 신체적 공격, 치료진에 대한 공격 등에 높은 응답율을 보였다. 강박처치의 부작용에 대한 지각은 입원환자의 경우 정신상태의 악화, 자해의 증가 등에 대해 보다 민감하게 반응 하였고, 실제로 경험한 부작용에 있어서는 직원들의 경우 피부박탈을 더 강조한 반면 환자군에서는 호흡곤란, 정신 상태의 악화 등을 강조하였다. 강제 처치에 대한 대체치료 방법으로는 환자군에서 면담을 중요시한 반면 직원군에서는 격리실의 이용을 강조하였다. 신체억제와 고용량의 정온화를 비교한 것은 환자군에서 신체억제가 더 효과적이라고 하였다. 신체억제 동안 느끼는 감정에 대한 지각에서 환자군은 슬픔을 가장 많이 보고하였고, 직원군은 적개심을 가장 많이 느낄 것으로 추정하였다. 신체억제의 시간에 대해서는 환자군이 긴 것으로 지각하고 있으며, 이상적인 신체억제의 시간은 환자군이 짧은 것이 좋다고 생각하고 있었다. 본 연구 결과 정신과 입원환자들과 병원직원들은 강박처치에 대하여 유의한 지각의 차이가 있다는 것을 알았으며 정신병원내에서 강제처치를 실시할 때에는 명확한 강박처치 시행에 대한 규준에 따라야 할 것임을 확인할 수 있었다. Objectives : The purpose of this study was to examine different perceptions of physical restraint and their nature between psychiatric inpatients and hospital staffs in a mental hospital and to provide baseline data for establishing the practicing standard of this therapeutic maneuver. Methods : Two hundred and two psychiatric inpatients who experienced physical restraint and 103 hospital staffs who frequently used this maneurer were surveyed with a questionnaire regarding indications, complications, alternative methods, emotional influences, duration of treatment and subjective effects of restraint. Results : Regarding indications of physical restraint, the inpatient group had negative viewpoint on the most items except "physical assault to other patients". Regarding the perception about possible complications of this treatment, the inpatient group had more concerns about "deterioration of mental status" and "increasing risk of self-injury". For experienced complications, staffs stressed "skin abrasion " while inpatients believed of "respiratory difficulties" and "deterioration of mental status" more frequently. As alternative methods of physical restraint, "increasing frequency of interview" was suggested by the inpatient group and "using seclusion room" was favored by the staff group. The inpatient group had an impression that physical restraint was more effective than high-dose neuroleptic tranquilization. For suspected emotion during this procedure, the inpatient group reported "sorrow" most frequently while the staff group presumed that "hostility" might be most frequent. Inpatients estimated that the average duration of physical restraint was longer than staffs did. Ideal duration of physical restraint was shorter in the inpatient group. Conclusion : These results suggest that there are definite differences in the perception of physical restraint between psychiatric inpatients and hospital staffs. Formal practing guideline for restraint should be set up with careful attention for these differences to maximize the therapeutic effect of this maneuver.

김은영,정흥호,정호승,조환익,황주찬,최상원 한국환경과학회 2004 한국환경과학회지 Vol.13 No.9

Physicochemical characteristics of Kwangyang Bay, have been investigated on the effects of inputting rivers just after rainy season in summer 2003. The results ranged from 4.96~8.01 mg/L for DO, 1.16~3.09 mg/L for COD, 7.21~67.71 μM for DIN and 0.12~121.84 μM for phosphate. The COD of Yeosu Area was 1.19~3.09 mg/L, Kwangyang Area was 1.23 ~ 2.76 mg/L. The COD of Wallae cheon in Yeosu Area was 3.09 mg/L and Donghoan in Kwangyang Area was 2.76 mg/L. The reason of high COD might be industrial sewage of organic chemical plants and iron foundry. DIN of Yeosu Area and Kwangyang Area were 7.21--63.43 μM and 8.43 67.71 μM respectively. The average phosphate of Yeosu Area was 23.65 μM. The source of phosphate might be industrial sewages of fertilizer plant and phosphate gypsum stocked with high amounts. The metal concentrations were measured in the range of 1.01~175.10 ㎍/L for Cu, 0.13~1.78 ㎍/L for Cd, 1.13~5.21 ㎍/L for Pb, 1.58~13.57 ㎍/L for Cr and 1.07~20.68 ㎍/L for As. The average Cu concentration was 78.99 ㎍/L in Kwangyang Area. The source of Cu might be industrial sewage of iron foundry. The average Cr concentration of Yeosu Area was 9.07 ㎍/L. That is 2 times higher than Kwangyang Bay 5.74 gg/L, because of sewage of chemical plants.

교량의 실시간 거동 모니터링을 위한 GPS의 적용

박운용,정성모,곽두호,이흥규 東亞大學校 大學院 1999 大學院論文集 Vol.24 No.-

Real Time Kinematic GPS will allow a multitude of monitoring, navigation and engineering applications. Applications inclued real time deformation and movement monitoring and real time automated plant control. In a low dynamic environment, with a short baseline length, it is possible to position a roving receiver to an approximate accuracy of less than 5mm within a few seconds of thestart of the ambiguity. One Engineering application is the monitoring of the movement of cable suspension bridges. Such structures are capable of movements of up to a few meters under adverse wind conditions or heavy traffic loads. The use of relative OTF positioing at strategic points upon the bridge would allow close monitoring of the bridge's movements and calculate deformation and long-term deterioration factors for the bridge. Future bridge designs and traffic management schemes could also benefit from the monitoring system.

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.

김종덕,장재익,유문일,정흥우,권찬호,오두식,김창현 한국국제농업개발학회 2004 韓國國際農業開發學會誌 Vol.16 No.1

본 시험은 크릴 분말의 사료적 특성을 조사하고, 산란계 사료에 첨가하였을 때 계란의 생산성과 품질을 비교하기 위하여 수해하였다. 크릴 분말을 산란계 사료에 0, 1 및 2% 수준으로 첨가하여 216수에 6주간 사양시험을 실시하였다. 크릴분말의 일반성분은 수분 8.25%, 조단백질 50.52%, 조지방 16.67%, 조회분 15.72%로 단백질과 지방이 높은 동물성 사료원료였다. 그리고 무기질(15.72%), astaxanthin (10ppm) 및 콜레스테롤 함량 (780ppm) 또한 많았다. 산란율, 연파란율, 일일사료섭취량 및 난중은 처리간에 유의적인 차이가 없었다. 황고 및 난황색도는 크릴의 첨가수준이 높을수록 유의적으로 높아 산란계의 난질을 향상시키는 첨가제로서의 가능성을 보였다. 이상의 결과를 볼 때 크릴 분말은 단백질과 지방이 높은 동물성 사료이며, 산란계에서 천연착색제로의 가능성을 보였다. This experiment was conducted to evaluate the chemical composition of Antarctic Krill(Euphausia superba Dana) meal as feed, and to investigate the effect of its supplementation on productivity and egg quality of laying hen. A total of 216 layers at the age 43 weeks in commercial cage were fed for 6 weeks with 3 different diets containing 0, 1, and 2% Krill meal (KM). The chemical composition of KM was consisted of moisture 8.25%, crude protein 50.52%, crude fat 16.67%, curde ash 15.72%, indicating that KM contains large amount of protein and fat. Krill meal also contains large amounts of mineral(15.72%), astaxanthin(10ppm) and cholesterol(780ppm). No differences were found in egg production, broken and soft eggs, and feed intake among treatments. Dietary supplementation of KM resulted in increased egg yolk height(6.1㎜) and yolk color (2) compared with those of control, suggesting that KM can be used as a feed additive for yolk quality improvement. According to the results of this study, Krill meal can be supplemented in laying hen diets as protein and fat sources, and natural coloring pigment.
