The objective of this study is to establish the application method of environmental information system which is related to hazard identification for Health Risk Assessment. For establishing the environmental information system, fourteen hazardous chemicals were chosen and applicated to the database network such as RTKNET(Right Know Net), MSDS(Material Safety Data Sheets), TRI(Toxic Release Inventory), IRIS, AIRS, etc. The searching method of environmental information is classified to three sections such as the domestic commercial information company, international database agencies, and internet. Recently the importance of environmental information is being emphasized because it is essential 10 use database system in the field of environmental studies. Most of the foreign research organizations are communicating actively for information exchange, and the improvement of the quality of research. It is required to accumulate the data and develop them to database for future research.

In order to evaluate the artificial skin for burn would covering materials, copoly(N. carbobenzoxy-L-Iysine-L-leucine)s were prepared by Ipolymerization of N - carbobenzoxy-L- I sine anhydride and L-leucine anhydride in homogeneous solvents using triethylamine as an initiator. The synthetic polypeptides and the oxter type polyurethane(PV)of medical grade were used as the sheet type membranes were prepared ; monolayer membrances were composed of only the polypeptides, bilayer membranes and blend membranes were controlled by composition of the polypeptides and PU. Test of the swelling degree, mechanical tensile strength, elongation, oxygen permeability, water-vapor loss and In vitro degradation treated by pretense TV of samples of artificial skin were measured by adequate methods so as to mechanical, physincal characterization and biodegradation. As a result, all the values of samples were found to be similar to desired value of skin which was nature. The Artificial skin based on polypeptides can be considered as ideal burn wound covering materials.

A Study has been conducted experimentally on heat transfer characteristics of louvered fin heat exchangers with various louvered positions in air. The experimental results are as follows; 1. Mean heat transfer coefficient is increased with increasing air velocity and decreasing temperature difference. The maximum value of heat transfer coefficient shows at 10㎜ backward louvered fins. 2. Pressure drop is increased with increasing air velocity and apparently depended on the louvered positions at V>10m/sec. 3. $\bar{h}/{\Delta}P$ is decreased with increasing air velocity and its maximum value shows at 10mm forward louvered fins and its minimum value shows at plate fins.

지난호에 이어 국내의 특허 검색에 관해 알아보도록 하겠다. 이제 국내에서도 특허의 데이터량이 방대하여 수작업으로 특허 조사를 실시하는 것은 거의 불가능한 상태이며 특허 자료의 대부분이 온라인으로 되어 그 검색이 용이해졌다.

척수장애 남자 환자의 성재활 지식, 성생활 만족 및 성재활 교육 요구

김선정,임지영,조인숙,함옥경,Kim, Sun-Joung,Lim, Ji-Young,Cho, In-Sook,Ham, Ok-Kyung 한국가정간호학회 2008 가정간호학회지 Vol.15 No.2

Purpose: We measured the knowledge, satisfaction, and education needs in sexual rehabilitation of male patients diagnosed with a spinal cord injury. Methods: We recruited 104 patients from a general rehabilitation hospital. Data were collected between April 4 and May 9, 2008. Knowledge of sexual rehabilitation, satisfaction, and educational needs were measured using self-report questionnaires. Results: Points for knowledge of sexual rehabilitation were 6.75 out of 20, sexual satisfaction was 3.02 out of 5, and demand for sexual rehabilitation education were 3.54 out of 5. Most (93.27%) of the patients wanted to have a sex life, and many (75%)were willing to participate in sexual rehabilitation education. There were no differences in knowledge or satisfaction based on general characteristics. However, sexual satisfaction of the university graduates was higher than the lower education group. Conclusion: Male patients with spinal cord disorders are interested in a sex life and demand sexual rehabilitation education. These findings should support the development of sexual rehabilitation programs.

Purpose: Little is known regarding the extent to which dying patients with chronic obstructive pulmonary disease (COPD) receive life-sustaining procedures and palliative care in U.S. hospitals. We examine hospital cost trends and the impact of palliative care utilization on the use of life-sustaining procedures in this population. Methods: Retrospective nationwide cohort analysis was performed using National Inpatient Sample (NIS) data from 2005 and 2014. We examined the receipt of both palliative care and intensive medical procedures, defined as systemic procedures, pulmonary procedures, or surgeries using the International Classification of Diseases, 9th revision (ICD-9-CM). Results: We used compound annual growth rates (CAGR) to determine temporal trends and multilevel multivariate regressions to identify factors associated with hospital cost. Among 77,394,755 hospitalizations, 79,314 patients were examined. The CAGR of hospital cost was 5.83% (P<0.001). The CAGRs of systemic procedures and palliative care were 5.98% and 19.89% respectively (each P<0.001). Systemic procedures, pulmonary procedures, and surgeries were associated with increased hospital cost by 59.04%, 72.00%, 55.26%, respectively (each P<0.001). Palliative care was associated with decreased hospital cost by 28.71% (P<0.001). Conclusion: The volume of systemic procedures is the biggest driver of cost increase although there is a cost-saving effect from greater palliative care utilization.

광합성 박테리아 및 담체를 이용한 하천의 저농도 질소, 인 처리 시스템 개발

김선정,이상섭,Kim, Sun-Jung,Lee, Sang-Seob 한국미생물학회 2010 미생물학회지 Vol.46 No.1

저농도 유기물, 질소, 인 제거를 위하여 독립영양 미생물인 광합성 박테리아를 이용한 회분식 실험 결과 초기값 $COD_{Cr}$ 37.3 mg/L, $NH_3$-N 4.0 mg/L, $PO_4^{3-}$-P 1.0 mg/L (C:N:P=100:10:1) 일 때 각각 87.4%, 46.3%, 79.7% 제거효율을 보였다. 혼합 광합성 박테리아, 세라믹 담체 및 담체 KSP01을 적용한 폭기식 반응기 실험 결과, 평균 유기물 72.7%, 암모니아성 질소 79.2%를 제거하였으며, pH 조절로 인산염 인을 최대 92.6%까지 제거할 수 있었다. 반응기 내 다양한 폭기 조건에서 암모니아성질소 제거를 확인한 결과, 1, 2 반응조에 10.2 L/min로 공기를 주입하였을 때 98.5%로 높은 제거효율을 보여주었다. 또한 하천수 적용시 암모니아성 질소 82.8%의 높은 제거효율을 확인하였다. 본 연구를 통하여 개발된 정화 시스템의 현장 적용시 저농도 질소, 인의 높은 제거를 보일 것으로 사료된다. We used phototrophic bacteria to remove low concentrated organic materials (CODCr), nitrogen and phosphorus. We applied $COD_{Cr}$ 37.3 mg/L, $NH_3-N$ 4.0 mg/L, and $PO_4^{3-}-P$ 1.0 mg/L (C:N:P=100:10:1) in the batch test, and the removal efficiencies were shown as follow: $COD_{Cr}$ 87.4%, $NH_3-N$ 46.3%, $PO_4^{3-}-P$ 79.7%. The aerobic process with mixed phototrophic bacteria, ceramic media, and media KSP01 showed the removal efficiencies of $COD_{Cr}$, $NH_3-N$, and $PO_4^{3-}-P$, each as 72.7% and 79.2%, respectively in the lab-scale reactor. The maximum $PO_4^{3-}-P$ removal efficiency reached 92.6% by adjusting pH. There were three conditions used to remove $NH_3-N$. The highest removal efficiency was 98.5% with 10.2 L/min of aeration in 1-2 reactors, and the result of applying river-water showed the high removal efficiency of $NH_3-N$ (82.8%). Therefore, this purification system may be useful to control nitrogen and phosphorus at low concentration in field.
