BACKGROUND: The number of biomass power plants is increasing around the world and the amount of wastes from power plants is expected to increase. But the bottom ash (BA) is not recycled and has been dumped in landfill. This study was conducted to find out functional groups of BA and adsorption rate of heavy metals on BA. METHODS AND RESULTS: The BA was dried in oven at 105℃ for 24 hours, and characterized by analyzing the chemistry, functional group, and surface area. The adsorption rates of heavy metals on BA were evaluated by different concentration, time, and pH. As a result, the adsorption amount of the heavy metals was high in the order of Zn> Cu> Cd> Ni and the removal rates of Zn, Cu, Cd, and Ni by BA was 49.75, 30.20, 32.46, and 36.10%, respectively. Also, the maximum adsorption capacity of BA was different by the heavy metal in the environmental conditions, and it was suggested that the isotherms for Zn, Ni, Cd, and Cu were adequate to Langmuir model. CONCLUSION(S): It is suggested that it would be effective to remove heavy metals in aqueous solution by using BA from biomass power plants in South Korea.

Purpose: The purpose of this paper was to develop a CD program of applied logotherapy to improve the quality of life of adolescents with terminal cancer. Method: Keller's ARCS theory and a model for developing internet learning materials(Kang) was applied to develop this program comprised four distinct phases: planning, designing, development, and execution stages. Results: This program was entitled 'Finding treasures in my life' and consisted of 5 sessions and its educational contents were made up as follows: "Treasure One" is 'learning three natures of the human mind', "Treasure Two" is 'learning creative value as first method to find meaning of life', "Treasure Three" is 'learning experiential value as second method to find meaning of life', "Treasure Four" is 'learning attitudinal value as third method to find meaning of life', and "Treasure Five" is 'Becoming the master of my life'. The sub-menu was made up of 'Beginning', 'What is it?', 'Travelling'. 'Laughing Song', 'End'. Conclusions: This CD program applied logotherapy with flash animation technique as an emotional and spiritual nursing intervention program for easier and more scientific application in pediatric oncology and hospice area.

Non-secretory multiple myeloma (NSMM) is a rare cancer of plasma cells characterized by the absence of detectable monoclonal M protein in the blood or urine. A 57-year-old woman presented with mandibular pain but without intraoral swelling. Imaging studies revealed multiple osteolytic lesions in her mandible and pronounced root resorption of the left mandibular second molar. Biopsy results showed atypical plasmacytoid cells positive for anti-kappa, CD138, MUM1, and CD79a antibodies, but negative for anti-lambda and CD20. These results were indicative of a malignant plasma cell neoplasm. No abnormalities were revealed by free light chain assay or by serum or urine protein electrophoresis, leading to a diagnosis of NSMM. The patient began chemotherapy in conjunction with bisphosphonate therapy and achieved remission following treatment. This case underscores the critical role of dentists in the early detection and prevention of NSMM complications, as the disease can initially present in the oral cavity.

Man-made cadmium (Cd) emissions can be transported between environmental matrices and the food chain. Food is the primary source of Cd exposure among general population as a consequence of the bioconcentration of Cd from soil. Chronic Cd exposure has been reported to be associated with chronic kidney disease, osteoporosis, diabetes, cardiovascular disease and cancer. The Joint FAO/WHO Expert Committee on Food Additives (JECFA) established the safe level of Cd intake as provisional tolerable monthly intake (PTMI) of $25{\mu}g/kg\;bw$ in 2010. The major food groups that contribute to the most Cd exposure are rice and grains, shellfish and sea food, meat including edible offal, and vegetables. A number of studies reported the high Cd contaminated levels in foods from polluted areas in Thailand. The results are of high concern since the contaminations occur in foods that are major Cd contributors. Thus, in this review, the current situations of Cd contaminated foods in polluted areas of Thailand are summarized. In addition, the Cd intakes from selected scenarios are estimated to assess the potential health risk to consumers and the suggestions are also included.

Purpose: The purpose of this study was to investigate the effect of nursing education using a CD ROM on the anxiety and knowledge of the patients having minor surgery. Method: Forty patients hospitalized in K hospital in Seoul from April to August 2002 participated in this study. In the experimental group, twenty patients received nursing education on the operational procedures and post-operational care. The control group, received conventional nursing care only. Anxiety experienced by patients was measured by Spielberger's State-Trait Anxiety Inventory, and knowledge was measured by an instrument developed by Rahe et al. The data were analyzed by SPSS statistical program. Result: There were no significant differences in anxiety level between two groups. However, subjects in the experimental group were found to have significantly higher postoperative knowledge levels than those in the control group, and were very satisfied with the CD ROM program. Conclusion: The nursing education program using CD ROM before minor surgery proved to be an effective nursing intervention to increase knowledge of patients and contribute to their self care after discharge. To decrease anxiety of the surgery, the nursing education program should be combined with supprortive emotional nursing intervention, such as touch, and massage.

본 연구에서는 CD-RAD Phantom을 이용하여 의료영상의 명세성 (image clarity)분석을 위하여 동일한 X선 영상을 대상으로 물리적 평가와 시각적 평가를 비교분석 하였다. 측정방법은 CD-RAD Phantom을 X선 조사하여 CR 영상처리장치를 통해 영상을 획득하였으며, 영상분석은 CD-RAD analyser program을 통한 통계학적 방법으로 물리적 평가를 시행하고, 동일한 영상의 시각적 평가는 관찰자 20명을 대상으로 blind test를 시행하였다. 분석결과는 Contrast-detail curve의 물리적 평가 IQF값은 25, 시각적 평가 IQF값은 30으로 분석되어 물리적 평가가 시각적 평가에 비해 우수하게 나타났다. 의료영상의 특성은 영상 판독자에게 영상의 정보 전달능력이 매우 중요하므로 객관적인 물리적 분석법과 시각적 분석법이 병행되어야 한다고 판단된다.

인산에 의한 카드뮴의 식물저감 효과를 증진시키기 위해 서로 다른 특성의 두 인산제재인 용과린과 $K_2HPO_4$를 선정하여 축분퇴비와 혼용하여 처리한 후 알타리무 내 카드뮴 흡수특성과 토양 내 카드뮴의 특성을 조사하였다. $K_2HPO_4$는 토양의 pH와 음하전도를 증대시켜 토양 내 유효태 카드뮴 함량과 알타리무내 카드뮴 흡수농도를 저감시키는 효과를 나타내었다. 반면 용과린은 토양의 pH와 음하전도를 감소시켜 유효태 카드뮴 함량과 알타리무 내 카드뮴 함량을 증가시키는 효과를 나타내었다. 축분퇴비와 인산비료와의 혼용은 인산 제재의 특성에 관계없이 인산비료를 단독으로 시용하였을 때 보다 알타리무 내 카드뮴 흡수농도와 토양 내 유효태 카드뮴 함량을 감소시키는 효과가 훨씬 우수한 것으로 나타났다. 인산비료나 축분퇴비의 시용에 의해 토양 내 인산과 카드뮴의 침전반응에 의한 난용성의 카드뮴 화합물의 형성은 나타나지 않았다. 토양의 pH와 음하전도는 토양 내 유효태 카드뮴의 함량과 알타리무 내 카드뮴의 함량과 고도로 유의한 부의 상관관계를 나타내었다. 본 연구의 결과를 통하여 인산비료와 축분퇴비에 의한 카드뮴의 부동화는 인산과 카드뮴의 직접적인 침전반응에 의한 것이라기보다는 토양의 pH와 음하전도의 증대에 기인된 카드뮴의 흡착증대에 의한 것으로 판단되어진다.

Objectives: Chronic diseases (CDs) continue to increase due to advances in medicine and increase in lifespan, affecting quality of life and resulting in economic loss through treatment costs. This study addressed the perception characteristics of the effectiveness of Korean medicine (KM) based on the existence of a CD to determine the national preference for KM treatment. Methods: Using data from the 2017 National Survey of KM Usage, we evaluated the perception on treatment effect of 16 diseases by dividing them into the CD group and the non-CD group. Response reliability was verified by applying the chi-square test (χ2-test) analysis method of the Statistical Package for the Social Sciences (SPSS) statistical program. Results: The analysis of the perception on effectiveness of KM for patients with CD (n = 1,050, 21.0%) and for patients with non-CD (n = 3,950, 79.0%) showed an overall similar trend for all the 16 diseases. The response rates of having some treatment effect were high for nine diseases namely, disc-related disease (CD: 70.7%, non-CD: 73.1%), osteoarthritis (CD: 72.3%, non-CD: 72.4%), frozen shoulder and shoulder pain (CD: 79.6%, non-CD: 81.4%), back pain (CD: 84.6%, non-CD: 85.0%), sprain (CD: 84.8%, non-CD: 84.1%), facial nerve paralysis (CD: 73.5%, non-CD: 71.7%), stroke (CD: 66.2%, non-CD: 62.8%), digestive disease (CD: 53.3%, non-CD: 50.0%), and common cold and rhinitis (CD: 44.7%, non-CD: 44.8%). Conclusion: The present results found that there was little difference in the perception on effectiveness of KM for each of the 16 diseases in patients with CD and non-CD, however, 70% or more of the respondents recognized some treatment effect on musculoskeletal disorders, regardless of the existence of CD. Preferential political support for KM treatment of chronic musculoskeletal disorders is recommended.
