The objective of this study was to evaluate the effect of applying alum (aluminum sulfate) and aluminum chloride on pH and pathogen populations of Hanwoo manure. A total of 36 steers (8 months old and averaging 300 kg in weight) were used in this trial and allotted to 9 pens (3 replication pens per group with 4 steers per experimental unit, 5 x 8 m). Chemical additives were applied as a top dressing with garden rake to a depth of 1 cm of manure with wood shavings in each treatment. The chemical amendments were control (without chemical amendments), 50 g of alum and 50 g of aluminum chloride/kg of Hanwoo manure. The experiment was carried out for 4 weeks. Adding alum and aluminum chloride to Hanwoo manure reduced (P < 0.05) pH compared to untreated controls during the 4 wk period. Both levels of the alum and aluminum chloride treatments tested decreased (P < 0.05) Escherichia coli and Salmonella enterica populations in Hanwoo manure at 2 and 4 weeks. It appears that the reduction in pathogen populations was primarily associated with the lower manure pH. If more strict environmental regulations are put into effect regarding pathogen populations from Hanwoo facilities, treating Hanwoo manure with alum and aluminum chloride may be a good management practice

Background: Irritable bowel syndrome (IBS) is one of the most common diseases of the digestive system, with a worldwide prevalence of approximately 20%. However, studies on constipation-predominant IBS in the elderly are scarce. Since Korea has the highest elderly population, with 38.2% of its population expected to be aged over 65 years by the year 2050, a study on the presence of IBS in this population is warranted. Methods: In the present study, IBS was defined and classified according to the Rome III criteria. This study was performed by using the case and control method at the outpatient Department of Family Medicine and the health promotion center of a hospital in Gwangju. The questionnaire for the demographic characteristics and dietary habits was administered to 128 patients with IBS and 193 controls. Results: Individuals who had a tendency of overeating for >3 days a week, compared to those who had a tendency of overeating for <2 days a week; those who had spicy food for >3 days a week, compared to those who had it for <2 days a week; and the time of meals showed statistically significant results. Meanwhile, the number and regularity of meals and having breakfast were not relevant factors. Conclusion: The weekly frequency of overeating and intake of spicy food as well as short time for meals are related to constipation-predominant IBS in the elderly aged above 65 years.

만성폐쇄성폐질환 환자에서 삶의 질과 우울 및 불안과의 관계

김삼철 대한임상건강증진학회 2011 Korean Journal of Health Promotion Vol.11 No.4

연구배경: 만성폐쇄성폐질환(chronic obstructive pulmonary disease, COPD) 환자들은 다른 만성질환이나 일반 인구에 비해 우울과 불안증상을 많이 가지고 있는 것으로 알려져 있다. 본 연구는 우울 및 불안증상이 COPD 환자의 삶의 질에 미치는 영향을 분석하기 위해 시행되었다. 방법: 저자는 광주광역시 지역 1개 종합병원 외래진료를 하는 129명의 COPD 환자를 대상으로 삶의 질을 평가하기 위해 Short Form-36 (SF-36)설문을, 우울 및 불안증상을 평가하기 위해 Primary Care Evaluation of Mental Disorder Patient Health Questionnaire (PRIME-MD PHQ)를 사용하였다. 우울 및 불안증상과 SF-36 점수와의 관련성을 평가하기 위해 Pearson 상관분석을 시행하였으며 영향의 정도를 평가하기 위해 다중회귀분석을 시행하였다. 결과: PRIME-MD PHQ를 사용한 검사에서 대상자의 48.8%가 주요우울증후군, 18.6%가 기타 우울증후군, 23.3%가 공황 증후군, 30.3%가 기타 불안증후군을 가지고 있는 것으로 조사되었다. SF-36의 신체요소 요약점수에는 우울증상, 호흡곤란정도 순으로 영향을 미치고, 정신요소 요약점수에는 우울증상만이 영향이 있는 것으로 판명되었다(P<0.05). 결론: 우울 및 불안증상은 COPD 환자에서 높은 유병률을 보이며 이 중 우울증상은 환자의 삶의 질을 유의하게 저하시키므로 COPD를 진료하는 의사들은 환자의 우울 및 불안증상에 관심을 가지고 적극적으로 치료하려는 태도가 필요하다. Background: It is well known that patients with chronic obstructive pulmonary disease (COPD) show symptoms of depression and anxiety more often than patients with other chronic illnesses or the general population. This study was designed to evaluate the effects of depression and anxiety on quality of life in patients with COPD. Methods: Quality of life was assessed using the Short Form-36 (SF-36) questionnaire and depression and anxiety symptoms were assessed using the Primary Care Evaluation of Mental Disorder Patient Health Questionnaire (PRIME-MD PHQ) in 129 patients with COPD visiting an outpatient clinic. We examined the correlations between the SF-36 scores and clinico-demographic features by Pearson's correlation analysis and the influence of depression and anxiety symptoms on the SF-36 scores by multiple regression analysis. Results: Of the 129 patients, 48.8% were diagnosed as having major depressive syndrome, 18.6% other depressive syndromes, 23.3% panic syndrome, and 30.3% other anxiety syndrome by the PRIME-MD PHQ. The physical component summary was affected the most by depressive symptoms followed by dyspnea (P<0.05). The mental component summary was only affected by depressive symptoms (P<0.05). Conclusions: The prevalence of depression and anxiety symptoms in COPD patients is markedly increased, and depressive symptoms decrease the quality of life in these patients. Thus, there is a need for physicians to assess for and recognize such symptoms and promptly administer appropriate interventions.

호스피스 환자 간병 가족의 우울 수준

김삼철,손효림,정다운 대한가정의학회 2009 Korean Journal of Family Medicine Vol.30 No.3

Background: It is expected that the number of families who provide caregiving for hospice patients will be increased in this society. Family caregiver will have fi nancial, psychological, social burden and stress related to this responsibility. Hospice patients, facing death, need not only biomedical therapy, but also systematic and continuous treatments such as mental or psycho-social intervention. The purpose of this study was to investigate the family caregiver's depression level and the associated factors. Methods: The survey was conducted with 62 family caregivers of the hospice patients who had been hospitalized at the Gwangju Veterans Hospital from December 2005 to May 2006. The questionnaire consisted of the general characteristics of the subjects, Beck's depression inventory (BDI) evaluating the depression level and family APGAR score evaluating the family function. Results: The mean age of the subjects was 58.2 years. The relationship with patients as 'spouse' accounted for 42 individuals (67.7%). The mean (± SD) BDI score was 25.3 (± 10.1) points and 58 percent of the subjects were suggested to have depression tendency (≥ 21 point). There was no relationship between the caregiver's depression level and their gender, religion, household income and Family APGAR score. However, the depression level was signifi cant related to the total caregiving duration (P = 0.001), visiting frequency of visitors (P = 0.004) and caregiving hours per day (P = 0.005). Conclusion: More than half of the family caregivers were suggested to have depression tendency. The depression level was infl uenced by the burden of caregiving and the visiting frequency of visitors. There is a need to activate social resources to share the burden of caregiving and to develop continuous and comprehensive care for hospice patients and their families. 연구배경: 국민소득의 증가와 보건의료수준의 향상으로 인 하여 질병의 조기발견과 치료율이 높아지고 있으나 완치가 불가능한 말기암과 만성질환자들의 호스피스 등록은 증가하 고 있다. 특히 이들은 더 이상 치료서비스를 제공받을 수 없어 의학적인 관심에서 제외되게 되고, 이들을 간호하는 가족들 은 스트레스와 부담감을 갖게 된다. 이에 본 연구에서는 호스 피스환자의 가족간병인의 우울 수준과 그에 영향을 미치는 인자를 알아보고자 하였다. 방법: 2005년 12월부터 2006년 5월까지의 기간 동안 광주광역 시의 일개 2차종합병원에 입원한 호스피스환자들의 가족 간 병인 62명을 대상으로 사회인구학적인 사항과 총 간병기간, 하루 중 간병시간, 방문객들의 방문빈도, 우울수준을 평가하 는 Beck's depression inventory (BDI), 가족기능지수를 조사하여 우울수준과 관련된 인자를 알아보았다. 결과: 조사 대상자의 평균(±표준편차) 연령은 58.2 (±12.0)세 였고 간병인과 환자와의 관계로는 배우자가 42명(67.7%)으로 가장 많았다. BDI 점수의 평균(±표준편차)은 25.3 (±10.1)점이 었으며 우울증의 기준점을 21점으로 하였을 때 36명(58%)에 서 우울증이 의심되었다. 간병기간이 길수록(P=0.001), 병원 방문객의 방문 빈도가 적을수록(P=0.004), 간병인이 하루 중 간병하는 간병시간이 길수록(P=0.005) 우울수준이 높아졌고 이들 세 변수의 설명력은 43.5%였다. 간병인의 성별이나 종교, 주 부양자의 수입, 가족기능지수 등은 간병인의 우울수준과 연관이 없었다. 결론: 호스피스환자 가족간병인의 절반 이상에서 우울증이 의심되었으며 간병시간과 하루 중 간병시간이 길수록, 그리 고 방문객의 방문빈도가 적을수록 우울 수준과 관련이 있는 것으로 나타났다. 앞으로 이러한 요인들을 개선하여 호스피 스환자 진료시 가족 간병인에 대한 배려로서 하루 중 간병시 간을 가족들이 서로 분담하거나 주변 방문객들의 격려를 자 원으로 활용하는 방안을 모색하는 것이 필요할 것으로 생각 한다.

Objectives: Despite the general assumption that the fewer hours of sleeping results in the higher severity of fatigue, few objective studies on the relevancy between the sleep quality and the level of fatigue severity of students in a medical school were made. Therefore, the purpose of this study is to reveal the relationship with the level of fatigue severity to subjective sleep quality by making a survey on medical school students. Methods: During the period from September 1 to 24, 2012, a survey is conducted on lifestyle, Pittsburgh Sleep Quality Index and fatigue severity scale for 180 students in their first to fourth year of OO university in Namwon, Jeollabukdo. To verify the relevancy between the level of fatigue severity and lifestyle of students of the medical school including the quality of sleep, the chi square test is conducted and to corroborate the relationship between the sleep quality and the level of fatigue severity, the multivariate logistic regression is made. Results: The multivariate logistic regression shows the fatigue severity of students over 5 in PSQI (odds ratio 16.701 95% confidence interval, 5.845-47.720; P<0.001) is significantly high compared to the others under 5 in PSQI while other life habits do not have any relevancy to the level of fatigue severity. Conclusion: In this study, many students in the medical school claim their sense of fatigue and in particular, the group without appropriate sleep shows the significantly high level of fatigue.

마늘껍질 생균제 급여가 산란계의 생산성 및 계란 품질에 미치는 영향

천세민,김삼철,주선태,양한술 경상대학교 농업생명과학연구원 2015 농업생명과학연구 Vol.49 No.1

본 연구는 마늘껍질 생균제 급여가 산란계의 생산성 및 계란 품질에 미치는 영향을 구명하고자 실시하였다. 60주령의 산란계(Hy-line Brown)를 4개 처리구(control, T1, T2 및 T3)로서 처리당 6반복, 반복 당 6수씩 총 144수를 공시하였다. 시험구인 T1, T2 및 T3는 마늘껍질 생균제를 각각 0.5%, 1.0%, 2%를 첨가하여 4주간 급여하였으며, 산란계의 생산성 및 계란 품질을 분석하였다. 난중은 처리구들간 유의차가 없었으나, 사료섭취량은 대조구에 비해 마늘껍질 생균제 0.5%와 2% 급여구인 T1 및 T3에서 높게 나타났다(P<0.05). 계란생산량은 모든 마늘껍질 생균제 급여구에서 대조구에 비해 높게 나타났으며, 마늘껍질 생균제 급여량이 증가할수록 계란 생산량 또한 증가하였다(P<0.05). 계란품질을 평가하는 난각강도, 난각두께, 난황높이 및 haugh unit 값에선 유의차가 없었으나(P>0.05), 마늘껍질 생균제 급여시 증가됨을 확인하였다. 난황 내 아미노산 조성 결과, T2에서 높은 황함유아미노산 값을 나타내었으며, T3에서 가장 높은 불포화지방산 함량을 나타내었다. 또한 마늘껍질 생균제 급여량이 증가할수록 불포화지방산 함량이 높게 나타났다(P<0.05). 따라서 마늘껍질 생균제 급여는 산란계의 사료섭취량 및 계란생산성 증가뿐만 아니라 계란 품질을 개선시키는 것으로 사료된다. This study was conducted to investigate the effects of dietary garlic-husk (GH) probiotics on the increasing of performance in lay hens and quality properties of egg. A total of 144, 60 week old Hy-line Brown lay hens were assigned to one of the following four dietary treatment; control (basal diet), T1 (basal diet with 0.5% GH probiotics), T2 (basal diet with 1.0% GH probiotics), and T3 (basal diet with 1.5% GH probiotics) for 4 weeks. Egg weight (g) was not significantly different among treatment (P>0.05). However, feed intake (g/day) was significantly higher in the 0.5% and 2% GH probiotics than the control (P<0.05). Dietary supplementation with GH probiotics led to increased egg production (%) in laying hens (P<0.05). Increasing the level of GH probiotics supplementation resulted in higher egg production values. Egg quality such as eggshell strength, eggshell thickness, albumin height and haugh unit values tended to be improved as in increase of GH supplementation as dietary supplementation with GH probiotics, but was not significantly different (P>0.05). Dietary supplementation with T2 resulted in significantly higher sulfur-containing amino acid value in egg yolk compared with other treatment samples but was not significantly different between the control (P>0.05). There was a linear increase in unsaturated fatty acid values with increasing levels of dietary GH probiotics, which was significantly higher in the T3 treatment sample (P<0.05).

The present study investigated the effect of inclusion of chromium propionate (Cr-P) and lysophopholipid (LPL) in diet on blood parameters and meat quality of Hanwoo steer. Feeding trial was performed from late fattening period to slaughter and blood parameters (insulin, blood glucose and non-esterified fatty acid (NEFA) concentration) and meat quality were examined. Total 4 experimental groups including control (no addition), T1 (Cr-P 0.2%), T2 (LPL 0.2%) and T3 (Cr-P 0.1% + LPL 0.1%) were employed. For blood parameters, insulin concentration in T1 and T3 showed an elevating patterns from 3.13 μU/mL to 3.35 μU/mL (T1) and from 4.38 μU/mL to 5.23 μU/mL (T3). The changes of NEFA in all groups were detected as a decreasing patterns according to days of feeding. However, significant difference was not found. In growth performance, T2 showed greater daily gain and T1 showed greater carcass yield compared to others. However, there were no significance in difference. In meat quality, T1 showed greater yield and intra-muscular fat levels and lower sharing force compared to others. However, significant differences were not detected.
