본 실험 은 한방에서 특히 산모의 산후 회복에 효과적 이라고 알려진 호박이 산욕기 산모의 혈액성상 회복에 어떤 영향을 주는지 알아보기 위해서 진행되었다. 호박을 주원료로 8가지 한방 생약재를 첨가하여 압출액을 만든 후분만 직후의 산모 50명 에 게 21일간 복용시키고 혈액을 채취하여 적혈구와 hemoglobin을 복용전과 비교하였으며 또 호박 및 한방 생 약재를 복용하지 않은 대조군과도 비교 하였다. 본 실험 의 결과 적혈구 수치 는 분만직후의 3.65 $\times$$10^{6}$/mm에 서 4.6$\times$$10^{6}$/mm로 증가하여 3.9$\times$$10^{6}$/mm인 대조구에 비하여 높은 증가효과를 보여주었으며 정상적인 적혈구 범 위 에 드는 결과를 보여주었다. Hemoglobin의 경우도 분만 직후 10.35 g/dL에서 복용 21일 만에 12.61 g/dL로 증가하여 대조군인 10.88 g/dL과 비교하였을 때 유의적인 증가효과를 보여주었다 Hemoglobin수치 역시 임신 초기의 평균적인 수준을 초과하였으며 정상의 범위에 속하는 수준으로 회복하는 결과였다. 이후 적혈구와 hemeglobin 뿐 아니라 좀더 자세한 혈액성상을 연구할 과제가 있으나 본 연구의 결과 호박을 주원료로 한 한방 생약재 추출액은 분만 직후 산모의 적혈구 수치 및 hemoglobin의 회복에 효과적이라고 생각된다.

Background: Occupational hazards in crop farms vary diversely based on different field operations as soil management, harvesting processes, pesticide, or fertilizer application. We aimed at evaluating the immunological status of crop farmers, as limited systematic investigations on immune alteration involved with crop farming have been reported yet. Methods: Immunological parameters including plasma immunoglobulin level, major peripheral immune cells distribution, and level of cytokine production from activated T cell were conducted. Nineteen grape orchard, 48 onion open-field, and 21 rose greenhouse farmers were participated. Results: Significantly low proportion of natural killer (NK) cell, a core cell for innate immunity, was revealed in the grape farmers (19.8±3.3%) in comparison to the onion farmers (26.4±3.1%) and the rose farmers (26.9±2.5%), whereas cytotoxic T lymphocyte proportion was lower in the grape and the onion farmers than the rose farmers. The proportion of NKT cell, an immune cell implicated with allergic response, was significantly higher in the grape (2.3±0.3%) and the onion (1.6±0.8%) farmers compared with the rose farmers (1.0±0.4%). A significantly decreased interferon-gamma:interleukin-13 ratio was observed from ex vivo stimulated peripheral blood mononuclear cells of grape farmers compared with the other two groups. The grape farmers revealed the lowest levels of plasma IgG1 and IgG4, and their plasma IgE level was not significantly different from that of the onion or the rose farmers. Conclusion: Our finding suggests the high vulnerability of workplace-mediated allergic immunity in grape orchard farmers followed by open-field onion farmers and then the rose greenhouse farmers.

Purpose: This study evaluates the effectiveness of providing frailty prevention services by living support workers through a case of community resource connection centered on living support workers to revitalize frailty prevention programs for vulnerable elderly people. Methods: This is a research study using secondary data from a neighborhood health-sharing project among the integrated health promotion projects of one public health center in Daegu Metropolitan City. To assess frailty effects pre-assessments were conducted in August, and post-assessments were conducted in November. Frailty was measured using a 20-item frailty instrument used in home healthcare projects. Data were analyzed using the chi-square, independent t-test, and paired t-test. Results: Preliminary measurements showed that older elderly had higher frailty scores than younger elderly. However, among the elderly aged 75 or older the total frailty score decreased statistically significantly from 5.97 points to 5.30 points (t=3.03, p=.003). Conclusion: The older elderly showed greater effect of frailty prevention than the younger elderly.

The objective of this study was to assess the variation in the concentration of assimilable organic carbon (AOC) in a drinking water resource, and investigate the characteristics of AOC derived from algae. The seasonal change in AOC at the Kamafusa dam corresponded to changes in the algal cell number. In order to understand the relationship between AOC and algae in a water resource and water purification plant, two kinds of laboratory experiment were performed. The algal culture experiment showed that extracellular organic matter (EOM) that was released during the growth of Phormidium tenue with M-11 medium led to significant increases in the AOC concentration, but no significant variation in the AOC concentration was observed with CT medium containing a high dissolved organic carbon concentration. The chlorination experiment showed that the AOC included in EOM was not easily removed by chlorination, although the AOC included in intercellular organic matter released from the algal cells by chlorination was removed under conditions where residual chlorine was detected.

Cellular phones are the most used electronic device everyday in modern life and are always in contact with our hands, Although many studies have revealed microorganisms living on our hands, there are only a few reports on the research about products or places which are in contact with our hands. Therefore, the purpose of this study is to verify microorganisms living in cellular phones. Microorganisms were scraped from cellular phones of students and professors from the clinical laboratory science department in Daegu Health College, and cultured at Brain Heart Infusion agar and MacConkey agar following API kit to identify them. The average colony number was $1.5{\times}10^2$ on BHI agar and $40{\times}10$ on MacConkey agar. There was no difference according to gender. In Gram stain result, Gram(+) Cocci showed the highest frequency. Also in BHI agar plates, Micrococcus spp and Acinetobacter baumannii identified with high frequency. Moreover, S. aureus, which is very well known as strong food poisoning bacteria, was isolated. Klebsiella pneumonia ssp pneumonia was isolated with the highest frequency from the MacConkey agar or S-S agar plate. From these results show, there are as many different microorganisms from cellular phones as from our hands. This is the first report isolating strong food poisoning bacteria in cellular phones. Since infection in hospitals have been an important issue to be aware of, it is equally necessary to investigate cell phones and products which hospital workers touch with their hands.

The market of dental materials industry in Korea will over 10 bilians $. If think concern of world market, we can know the possibility of market growth. In Korea, the technique of dental materials industry is low status. Then, special items income advanced countries. But advanced countries had been developed dental materials industry into high beneficial. Otherwise, Daegu Kyungbuk have several good points in dental materials industry. 1st, national dentisty university and three dental lab. college supplies abilitable human resources. 2nd, the possibility of support on basic industrial technology. Finally, the possibility of selection & attraction from many dental company. Then if Daegu Kyungbuk would be select & supported of dental materials Industrial special region, it can be think that will empower local economy, further national constitutional power. So we propose following three points, 1st. the deeper study on righteous of Daegu Kyungbuk dental materials industrial specialization. 2nd. investment on R & D of the region dental materials industrial. final, the support of venture circle.

Purpose: This study was conducted to examine the correlations among nursing professionalism, clinical practice satisfaction of nursing students. Method: The subjects were 184 nursing students recruited from one college located in D city. Data were collected using structured questionnaire, and analyzed with the PASW 21.0 program. Results: The results indicate that nursing students have levels of nursing professionalism, and clinical practice satisfaction that are higher than the median. Nursing professionalism showed differences according to plans for academic performance, major satisfaction, personality, and personal relations. Nursing professionalism was significantly correlated with clinical practice satisfaction, major satisfaction. Conclusion: Clinical practice satisfaction, and academic performance were the most influential factor predicting greater nursing professionalism. Thus, these factors should be considered when developing a program for enhancing nursing professionalism.
