감 품종별(도근조생, 고종시, 갑주백목, 차랑, 월하시, 상주둥시)로 감꽃을 개화기에 채취하여 동결건조 분말화한 감꽃분말에 함유된 유효성분을 분석, 비교하였다. 조지방 함량은 도근조생이 57.26%로 가장 높은 값을 보였으며, 유리당 조성은 fructose가 95~310 mg%, glucose는 75~281 mg%, sucrose가 7~28 mg%의 함유량을 나타내었고, 유기산 중 malic acid가 갑주백목(6월4일)에 225 mg%로 가장 많았고, tartaric acid도 189 mg%로 가장 많았다. 유리아미노산 중 hydroxy-L-proline은 월하시에 25.33 mg%, L-citrulline은 상주둥시(5월28일)가 58.83 mg%, L-threonine은 상주둥시(5월28일)가 11.88 mg%로 가장 많았다. 페놀산으로 caffeic acid는 갑주백목(6윌4일)이 1946 μg/100 g, phydroxybenzoic acid는 상주둥시(5월29일)가 417.8 μg/100 g, protocatechuic acid는 갑주백목(6월1일)이 181.1 μg/l00 g으로 가장 많았다. 따라서 감꽃에도 감이나 감잎에 못지않게 유용한 식품성분들과 기능성 성분들이 다량 함유되어 있어 새로운 식품 및 기능성 신소재로서의 가치가 매우 높다고 할 수 있다. This study was carried out to analyze useful components in freeze-dried persimmon flower powder made from six cultivars. The cultivars were Dogunjosang, Kojongsi, Kabjubaekmok, Chalang, Weolhasi and SangjuDungsi. Powder of persimmon flower was prepared by milling after freeze drying at -70℃. Crude lipid was the highest in Dogunjosang (57.26%). Major free sugars of the persimmon flowers were fructose (95~310 mg%), glucose (75~281 mg%)and sucrose (7~28 mg%). Major organic acids were malic acid (225 mg% in Kabjubaekmok (Jun. 4th)) and tartaric acid (189 mg% in Kabjubaekmok (Jun. 4th)). Predominant free amino acids were hydroxy-L-proline(25.33 mg% in Weolhasi), L-citrulline (58.83 mg% in SangjuDungsi (May 28th)) and L-threonine (11.88 mg% in SangjuDungsi (May 28th)). Major phenolic compounds in the persimmon flowers were caffeic acid (1,946 μg/100g in Kabjubaekmok (Jun. 4th)), p-hydroxybenzoic acid(418 μg/100g in SangjuDungsi (May 29th)) and protocatechuic acid(181 μg/100g in Kabjubaekmok(Jun. 1st)). The results suggest that persimmon flowers be potential materials as useful food ingredients.

The electrocardiogram is one of the most widely used diagnostic tools. Especially it is useful to the patients who have cardiovascular disease. Because elderly population are the fastest growing component of national population, I analyzed the frequencies of specific electrocardiogram findings in patients aged 65 years and older living in Gyeong-ju to collecting ECG data. Sinus bradycardia (17.0%) and Left ventricular hypertrophy (25.2%), QT prolongation (30.9%) were the most common abnormalities found in the population as a whole. Left-axis deviation (11.6% vs. 3.1%, p = 0.001) and right bundle branch block (11.9% vs. 4.1%, p= 0.001) were more common in men than women. First-atrioventricular block (2.2% vs. 5.5%, p = 0.025) and T wave abnormalities (4.1% vs. 13.2%, p = 0.001), left ventricular hypertrophy (21.6% vs. 28.0%, p = 0.049) were more common in women. QT prolongation were more common in 75 years and older (26.7% vs. 38.1%, p = 0.001). Left-axis deviation (9.4% vs. 3.9%, p = 0.024) and Right bundle branch blocks (9.8% vs. 3.0%, p = 0.003) were more common in men aged 65~74 years. Left ventricular hypertrophy (20.9% vs. 30.0%, p = 0.025) and T wave abnormalities (4.3% vs. 12.2%, p = 0.002) were more common in women aged 65~74 years. Atrial fibrillation (7.1% vs. 1.1%, p = 0.013) and left-axis deviation 17.6% vs. 2.1%, p = 0.001), Right bundle branch block (17.6% vs. 5.3%, p = 0.001) were more common in men aged 75 years and older. First-atrioventricular block (0% vs. 5.9%, p = 0.020) and T wave abnormalities (3.5% vs. 14.4%, p = 0.008) were more common in women aged 75 years and older. In conclusion, Left ventricular hypertrophy and sinus bradycardia, QT prolongation were most common electrocardiographic findings in as a whole. Left-axis deviation and right bundle branch block, fist-atrioventricular block, T wave abnormalities, QT prolongation were significantly different in age and gender. 심전도는 전 세계적으로 가장 널리 사용되는 진단적 도구로서, 특히 심혈관계 질환이 있는 환자에게 그 유용성이 크다. 현대 사회는 고령화 사회로 노인 인구에 대한 사회적, 의학적 관심이 높다. 이에 본 연구자는 노인 인구에 대한 심전도 자료를 수집하기 위해 동국대 경주 병원 외래 진료실을 방문한 65세 이상 노인 환자 737명을 대상으로 심전도 검사를 시행하였다. 좌심실 비대(25.2%), QT 간격 연장(30.9%)과 동성 서맥(17.0%)을 보인 경우가 가장 많았고, 좌축 편위 (11.6% vs. 3.1%, p = 0.001), 우각 차단(11.9% vs. 4.1%, p = 0.001)의 경우 여자 환자보다 남자 환자에서 빈도가 높았고, 1도 방실 차단(2.2% vs. 5.5%, p = 0.025)과 비정상적인 T파 양상(4.1% vs. 13.2%, p = 0.001), 좌심실 비대(21.6% vs. 28.0%, p = 0.049)의 경우 남자 환자보다 여자 환자에서 빈도가 높았다. 75세 이상 환자 군에서 QT 간격 연장(26.7% vs. 38.1%, p = 0.001)이 65세에서 74세 사이 환자 군에 비해 빈도가 높은 것 외에 유의한 차이는 없었다. 결론적으로 고령 환자에서 비정상적인 심전도 소견으로 좌심실 비대와 QT 간격 연장, 동성 서맥의 빈도가 높았으며 좌축 편위, 우각 차단, 1도 방실 차단 등은 성별, 연령대별로 유의한 차이가 있었다.

조준호,김강,최상철,이경록,정종필,고영춘 朝鮮大學校 附設 醫學硏究所 2008 The Medical Journal of Chosun University Vol.33 No.3

연구목적: 우리나라의 결핵약제에 대한 내성은 지속적으로 감소되고 있음에도 불구하고 여전히 적지 않은 환자를 보유하고 있는 상황에서 치료 실패의 중요한 요인이 되고 있다. 이에 결핵 내성률에 영향을 미칠 수 있는 인자들을 파악하고 이에 대한 예방 대책을 수립하는 것이 내성률 발생의 예방에 도움이 될 것으로 사료된다. 이에 저자들은 광주 소재의 한 2차 병원에서 결핵 약제 내성률 및 위험인자로 판단되는 요소들과의 상호관계를 조사하였다. 대상 및 방법: 2005년 3월 부터 2006년 2월 까지 광주 기독 병원 내과에서 치료받은 결핵 환자중 객담 결핵균 배양 검사상 양성으로 판명되어 약제 감수성 검사를 확인할 수 있었던 346명을 대상으로 의무기록, 면담 등을 통한 후향적 조사를 시행 하였다 결과: 346명중 한가지 이상의 약제에 내성을 보인 경우는 150명(43.4%)였고, 다제 내성 결핵은 72명(20.8%)였다. 조사 요인의 유무별로 약제 내성률을 조사하였을 때 흉부 사진의 침범 정도에 따른 약제 내성률 및 다제 내성률은 경증에서 36.3%와 6.2%, 중등도에서 36.1%와 22.6%, 중증에서 61.0%와 35.0%였다. 병변의 공동성 병변 유무에 따른 약제 내성률은 공동이 있는 군에서는 49.8%, 공동이 없는 군에서는 34.0%였다. 과거의 치료력 여부에 따른 약 제 내성률은 치료력이 없는 군에서는 19.7%였고, 치료력이 있는 군에서는 81.2%였다. 항 결핵제 복용의 규칙성 여부에 따른 약제 내성률은 규칙적 복용군은 31.7%, 불규칙적 복용군은 59.7%로 나타났다. 결론: 광주 소재의 한 2차 병원에서 조사한 약제 내성률 및 다제 내성률은 전국 평균치를 훨씬 상회하였다. 한편 과거 치료병력 및 약제의 불규칙 복용은 약제 내성률을 높이는 데에 기여하는 인자가 될 것으로 사료된다. 흉부방사선 사진 상의 폐 침범 정도, 공동성 병변의 존재도 약제 내성률 증가와 관련이 있는 것으로 보이나 보다 정확한 선후관계 분석을 위해서는 추가적인 전향적 연구가 필요하다. Background and objectives: Drug resistance is a major obstacle to the treatment of pulmonary tuberculosis (TB). This study was conducted to determine the prevalence of drug-resistant tuberculosis and its associated factors at a secondary hospital in Gwangju. Materials and Methods: A retrospective one-center analysis was conducted, with 346 pulmonarytuberculosis patients who underwent drug susceptibility tests for M. tuberculosis at Gwangju Christian Hospital from March 2005 to February 2006. Results: The following percentages of subjects were found to be resistant to at least one drug and to have multidrug-resistant tuberculosis (MDR-TB), respectively: 43.4% and 20.8% of all the subjects; according to the severity of the chest X-ray findings, 36.3% and 6.2% in the mild group, 36.1% and 22.6% in the moderate group, and 61.0% and 35.0% in the far- advanced group; according to the presence of a cavitary lesion, 49.8% in the cavitary-lesion group and 34.0% in the noncavitary-lesion group and according to the history of previous tuberculosis treatment, 81.2% in the group who have had treatment and 19.7% in the group who have never had treatment. The resistance rate according to the regularity of antituberculosis drug medication was 31.7% in the regular medication group and 59.7% in the irregular medication group. Conclusion: The drug resistance rate was increased by the history of previous tuberculosis treatment and the irregular medication. As to whether the severity of chest X-ray findings and the presence of cavitary lesions have a correlation with drug resistance, prospective studies are needed for more accurate results.

이 논문의 목적은 ① 경북 지역의 노인 주거복지시설의 현재 상황을 조사하고 ② 노인의 욕구를 반영할 수 있는 개선의 방안을 모색하는 것이다. 특히 이 논문은 노인 시설에서 일하고 있는 사회복지사 뿐만 아니라 주거하고 있는 노인의 만족도 둘 다를 탐구한다. 이 연구는 다음과 같은 것을 제안하고자 한다.; ① 노인 주거복지시설과 노인 요양복지시설의 통합운영, ② 법인을 활성화 할 수 있는 전문가 집단의 이사 추천제도 도입 필요, ③ 시설간 연대를 통한 직원의 공개 채용 및 복무 규정 마련을 통한 투명성 확보, ④ 시설간 전문 서비스 구축을 위한 협조 체계 구축, ⑤ 지역 사회 연계와 관련한 모범 사례 표창, ⑥ 전문직 종사자의 증원 및 처우 개선 등이다. The population of elderly person grows gradually in the society. In contrast, the number of elderly person stayed at the social facility is decreased. This is probably because the facility for the elderly person does not meet the needs of the elderly. Thus this study aimed 1) to examine the current status of facilities for elderly person in GyeongBuk province, and 2) to analyze the needs of the elderly so the facilities meet the needs more properly. We examined the degree of satisfaction both of the elderly staying at the facility as well as social workers working in the facility. Moreover, their relationship to the community, environment of the facility, and their management were analyzed. The activities served by the facility were divided into a general one and a specialized one. Whole facilities for the elderly in the GyeongBuk province were examined. The results suggest the necessity of the followings: 1) the combined management of both facilities for residency and welfare of the elderly, 2) a group with expertise for activating the management, 3) more clear criteria for the recruitment of qualified social workers, 4) the cooperative work between the facilities, 5) propagating the good examples for the establishment of relationship to the community, and 6) the needs for increasing the number of social workers and their income.
