Background: Smoking-related chronic obstructive pulmonary disease and chronic asthmatic bronchitis, which are the most important causes of chronic airflow obstruction (CAO), can occur together in a pat,ient and the prognoses of these two diseases are different each other.Objective and method: To estimate the extent of asthmatic component in patients with CAO and to evaluate the role of atopy as a predictable index for reversibility of airflow obstruction, 89 CAO patients who were older than 40 years were examined retrospectively. Result: Only 15 patients (16.8%) showed an increase of >15% in FEV20 to inhaled salbutamol (short-term responder). However, 18 out of 32 patients (56.3%), who were not responded significantly to inhaled bronchodilator and performed a follow-up lung function study, showed an increase of ) 15% in FEV20 to anti-asthmatic therapy including corticosteroid for 3-4 weeks (long-term responder). Peripheral blood eosinophil count only was different between short-term responder and short-term nonresponder, and there was no difference in all of the measurements between short-term responder and long-term responder. However, there were significant differences in smoking, wheezing on auscultation, peripheral blood eosinophil counts, serum total IgE levels, and MAST atopy score between long- term responder and long-term nonresponder. The increase in FEV, following shortor long -term therapy was related to peripheral blood eosinophil counts and MAST atopy score, and it was significantly great,er in patients with high eosinophil counts or high atopy score.Conclusion .: About 2/3 of patients with CAO who were older than 40 years had an asthmatic component ap atopy may be useful to predict good bronchodilator response to anti-asthmatic therapy.

사용자의 이동성으로 인하여 이동컴퓨팅 환경에서 안정된 서비스 품질(QoS)로 사용자가 원하는 정보를 제공받는데 많은 한계점이 있다. 이동성과 더불어 무선 네트워크의 낮은 대역폭, 높은 전송지연 등의 고유 특성을 부분적으로 보완하기 위해서 유효 데이터의 캐슁 혹은 프리페칭 기법의 적용이 심도 있게 연구되고 있다. 본 논문은 사용자의 선호도(Preference) 즉, 관심도(Interest)와 인기도(Popularity)를 고려한 IP기반 프리페칭 기법을 제안한다. IP기반 프리페칭은 사용자의 선호도를 사용자별 특정 정보에 대한 개인적인 성향을 관심도로, 특정 정보의 일반적인 성향을 인기도로 분리, 적용함으로써 프리페칭의 유효성을 높인다. 제안된 방법은 기존의 방법들보다 높은 정보의 활용률과 정보검색 실패율을 최소화시키는 성능을 보이고 있다. Mobile computing environment is known to be quite difficult to provide user with a stable QoS(Qualify of Service) due to its mobility nature. In order to protect the inherent characteristics of wireless network such as low bandwidth and high transmission delay along with the user's mobility, many works are conducted to apply caching and prefetching methods. This paper presents a novel prefetching technique which is based on user's preference, that is, interest and Uuかity. It tries to improves the effectiveness of prefetching by separating and appling the interest with personal tendency of a given information, and the popularity with general tendency of the information. The proposed scheme shown relatively superior performance in terms of the utilization ratio of prefetched information and the failure ratio of information retrieval than the existing methods.

Background : Changes in airway mucosal osmolarity are an underlying mechanism of bronchoconstrictive responses to exercise and hypertonic saline (HS). The purpose of this study was to examine whether an osmotic challenge test using HS can predict exercise-induced bronchospasm (EIB) in asthma patients. Methods : Thirty-six young male asthmatic patients underwent bronchial challenge tests based on 4.5% HS, exercise (> 24h later), and methacholine (MCh) at the Chonnam National University Hospital. The relationships between responses to HS and exercise, and between MCh and exercise were evaluated. Results : The maximal fall in forced expiratory volume in one second following exercise was significantly higher in the HS-responders (n=19) than in the HS-nonresponders (n=17, 35.9±4.1% vs. 17.9±2.7%, ρ<0.001), and there was a significant correlation between the severity of EIB and HS-airway hyperresponsiveness (AHR). When compared with the MCh-AHR test in terms of predicting EIB, the HS-AHR test showed higher specificity (71.4% vs. 42.9%), but a lower sensitivity (58.6% vs. 89.7%) and negative predictive value (29.4% vs. 50.0%). At the moderate AHR cutoff value, the MCh-AHR test had a specificity that was comparable with and predictive values that were higher than those of the HS-AHR test. Conclusions : The HS-AHR test was more specific than the MCh-AHR test, but was less sensitive and had a poorer negative predictive value, which in combination preclude the use of the HS-AHR test as a screening tool for EIB. The MCh-AHR test had a cutoff value for moderate AHR that may be more useful for predicting EIB in asthmatic patients.

Bone mass is accumulated at growth period and women can reach about 90% of maximum bone mass by 18 and bone growth is very important. Thus examination of bone density of girls' high school students is needed, but materials of bone density are lacking. This study examines health conditions, living habits, eating behaviors, measures bone density and obtains the following results in order to evaluate influence of eating habits of girls' high school students majoring music and dance on their bone density. As a result of examining general items with subjects, average height and weight were 162.3 cm and 53.9 kg in music students and 165.5 cm and 51.0 kg in dance students and their weight was showed significant difference. Body Mass Index (BMI) was 20.4 kg/㎡ in music students and as 18.6 kg/㎡ in dance students and music students were significantly higher than dance students. As a result of examining health conditions and living habits, dizziness and vertigo were 15.4% in music students and 53.8% in dance students and dance students were significantly higher. Daily average sleeping hours were highest at ‘6~7 hours' as 34.6% and 38.5% in music and dance students respectively, but 61.5% of music students responded it was sufficient and 65.4% of dance students responded it was insufficient. 88.5% of music students didn't perform regular exercise and 84.6% of dance students did regular exercise and there was significant difference between two groups. As a result of examining their eating behaviors, 71.2% of subjects have breakfast. Bone density was 705.0 g/㎤ at music students and 715.3 g/㎤ at dance students and that of dance students was higher than that of music students. In the relationship between BMI and bone density, ‘16~19.9' of BMI corresponded to 712.4 g/㎤ of bone density, ‘20~24.9' of BMI to 709.8 g/㎤ of bone density and ‘over 25' of BMI was 741.5 g/㎤ of bone density and there was significant difference. In sum, since dance students who did regular exercise had higher bone density, it was known that exercise is profitable factor to increase bone density and more researches on promoting bone health of youth are needed in future.

광주ㆍ전남 일부 지역 중학생들의 BMI 수준에 따른 식행동, 체형인식 및 체중조절 양상에 관한 연구

최인선(In-Seon Choi),노희경(Hee-Kyong Ro) 한국식품영양과학회 2010 한국식품영양과학회지 Vol.39 No.3

본 연구는 광주?전남지역 중학생 732명을 대상으로 BMI 수준에 따른 식습관, 식행동, 체형인식 및 체중조절 실태에 대해 조사하였으며 이에 대한 연구 결과를 요약하면 다음과 같다. BMI 수준에 따른 조사대상자의 분포는 남학생이 저체중군 27.8%, 정상체중군 45.9%, 과체중군 26.3%이었으며, 여학생은 저체중군이 26.2%, 정상체중군 53.6%, 과체중군 20.2%이었다. 남녀 중학생의 평균 BMI는 각각 20.7±1.0과 20.6±0.2이었다. 점수로 평가한 식습관과 식행동에서 남자중학생은 과체중군이 저체중군에 비해 빨리 먹는 점수가 높으며, 저녁식사의 양과 야식섭취 및 식품선택 시 기호보다 영양을 고려하는 점수는 낮았다. 여자 중학생은 과체중군이과식과 스트레스 시의 음식 섭취와 식품선택 시 가격보다 영양을 고려하는 점수는 높았고, 야식 점수가 낮았다. 조사대상자의 신장은 남자 중학생 저체중군이 정상체중군과 과체중군에 비해 유의적으로 낮았으나, 여자 중학생은 그룹 간 차이가 없었으며, 남녀 중학생 모두 실측한 신장보다 더 크기를 원하였다. 조사대장자의 체중은 남녀 중학생 모두 그룹간의 차이가 유의적이었다. 남자 중학생은 과체중군에서만 체중감소를 희망한 반면, 여자 중학생은 과체중군뿐아니라 정상체중군에도 체중의 감소를 희망하였는데, BMI가 클수록 원하는 체중과 실측체중간의 차이가 컸다. 본 연구대상자들의 인지체형은 남녀 중학생 모두 해당 군별 체형에 근접하였으나, 정상체중군에서 인지체형에 대한 왜곡경향이 높았으며, 희망체형과 인지체형의 차이가 과체중군에서 가장 컸다. BMI가 높을수록 체중조절에 대한 관심과 경험이 높았는데, 남자 중학생은 건강을 위해서, 여자 중학생은 날씬한 외모를 갖고 싶어서가 체중감량의 이유로 가장 많았다. BMI가 클수록 체형만족도가 낮으며, 희망체형과 인지체형간의 차이 값이 컸으나 스트레스는 BMI가 낮을수록 컸다. 또한 희망체중과 체형에서 실측체중 및 인지체형을 뺀 값이 클수록 체형만족도가 낮았다. 본 연구의 결과, 과체중군은 정상체중군과 저체중군에 비해 과식, 스트레스 시의 음식섭취에서 보다 바람직하지 않았으며, 스트레스와 체중조절관심도 및 경험이 더 많아, BMI 수준에 따라 식생활 양상에 차이를 보였는데, 과체중군의 식행동과 태도가 보다 바람직하지 못하였다. 따라서 남녀 중학생을 대상으로 올바른 체형인식과 더불어 체계적인 영양교육의 필요성을 제시하는 바이다. This study was performed to investigate the food habits, eating behaviors, perception of body shape, statuses of body weight control by BMI (Body Mass Index) of 732 middle school students in Gwangju and Jeonnam. The results of this study were compared among under weight (UW), normal weight (NW), and overweight (OW) groups according to BMI levels. In the OW group, female students had low scores in eating at night only, while male students had low scores in eating at night, eating speed, and food selection. All subjects wanted more height than measured. Only male students in the UW group wanted weight loss, whereas female students in the OW and NW groups did. Higher BMI in female students resulted in more weight difference between measured and wanted. All subjects responded properly themselves in perception of body shape but the OW groups showed a big difference between their present weight and wanted weights. Higher BMI in all students corresponded to more interest in concern and experience of weight management. In the male students, the reason for weight management showed high tendency in being healthy, whereas the female students had high tendency in having a slender figure. Higher BMI in all students corresponded to bigger difference between wanted and perceived body shape. In contrast, lower BMI in all students meant more stress. Greater difference between wanted and measured weight and greater difference between wanted and perceived body shape corresponded to less satisfaction in body shape. In conclusion, compared to the NW and UW groups, the OW group had overeating habits highly linked to stress. Also the OW group didn't have desirable eating behaviors and attitudes because of their greater interest in concern and experience of weight control and stress accumulation, and finally there was difference in food habits and behaviors according to the BMI level. Therefore these results suggest that effective nutritional programs should be developed including correct body image and good dietary habits.

N/A Objectives: In the consideration of the variabilities of the test results related to the technical or the biologic factors, the standardized methods performing the ventilatory lung function test by spirometry were recommended by American Thoracic Society (ATS). However, even though most of the modern pulmonary function laboratories perform the lung function tests using the computerized standard spirometers and the standard performing methods, it is necessary to evaluate the intraindividual technical variabilities of the spirometric test results; in addition, there is no article about it published in Korea. Methods : The lung function tests of 13 normal subjects were performed in each laboratories of Chonnam University Hospital, Wonkwang University Hospital, and Kwangju Christian Hospital. Results: 1) The interlaboratory variability of the spirometric test results was significantly larger than the intralaboratory(Coefficients of Variation, CV: 7.25 ±5.33% vs 2.79±1.59%, p<0.05 in FVC; 7.23±5.22% vs 2.26±1.70%, p<0.05 in FEV₁). 2) The mean lung function test results measured by one machine were significantly larger than those by another(4.29±0.89L vs 4.13±0.90L, p<0.05 in FVC; 3.71±0.81L vs 3.51±0.80L, p<0.05 in FEV ,). However, the intermachine variability was not significantly different from the intramachine. 3) The intertechnician variability of spirometric test results measured by three different technicians was not significantly different from the intratechnician. 4) The significance level of intraindividual difference in spirometric test results were 12% in FVC and 12% in FEY, between the different laboratories, 5% in FVC and 6% in FEV₁, between the different machines, 3% in FVC and 4% in FEV₁, between the different technicians. Conclusion : These results suggest that the spirometric test must be interpreted cautiously under the consideration of such a variability, and that it is necessary to adhere strictly to the recommended methods of the equipment quality control and the maneuver performance, and to check regularly the inter and intralaboratory variabilities,

본 연구는 동물실험을 통해 혈청 지질 개선효과에 영향을 미칠 수 있는 몇몇 비소화성 물질과 칼슘에 대한 정보를 얻기 위하여 올리고당, 아가, 사포닌, 탄닌 및 칼슘 등을 고지방식이와 함께 흰쥐에게 단독 또는 혼합 급여하여 이들 첨가 급식이 지질대사 및 담즙산 배설에 미치는 영향을 관찰하여 다음과 같은 결과를 얻었다. 혈장 중의 총 지질 농도는 대조군에서 가장 높은 경향이었으며 올리고당군, 아가군 및 칼슘 탄닌군이 유의적으로 낮았고 다른 여타 실험군은 대조군과 유의적인 차이를 보이지 않았으나 낮은 경향이었다. 동물실험 성적 중 올리고당, 사포닌 및 탄닌 첨가 급식은 뚜렷한 혈청 지질 개선효과를 나타내지 않았으나 모든 칼슘 첨가군과 특히 아가 첨가군 등은 대조군에 비해 분중 담즙산 배설량의 증가와 혈장 총 콜레스테롤 농도가 낮아지는 경향 등 혈청 지질 개선효과를 나타내었다. This study was conducted to investigate the effect of nondigestable substances and calcium such as oligosaccharide, agar, saponin, tannin and calcium on the reduction of lipid status in rats fed high fat diet. In order to make the observation, the lipid content in plasma, liver and the feces, and bile acid excretion were measured for 4 weeks. The results obtained from this research are as follows. Concentration of total lipid in plasma seemed highest in the control group and were significantly lower in groups oli-gosaccharide, agar and calcium-tannin, compared to the control group. Concentration of total cholesterol in plasma was significantly lower in groups oligosaccharide, agar, calcium and calcium-saponin, compared to the control group. The improvement in lipid status seems to be insignificant with oligosaccharide, saponin and tannin group, but the groups supplemented with calcium and agar group, more so in agar, showed increase in total bile acids excretion in feces and decrease in total cholesterol in plasma, compared to the control group. These evidence seems to indicate improvement of the plasma lipid status by calcium and agar supplementation.

This study was carried out to compare the effect of smoking on dietary habits, nutrient intakes and blood lipid profiles in 173 adult male drinkers. Subjects were classified by two groups, alcohol-only and alcohol-smoking, based on their alcohol or smoking habits. The BMI of the alcohol-smoking group was significantly lower than those of alcoholonly group. In dietary habits, the alcohol-smoking group had higher irregular breakfast and dinner intakes than alcoholonly group (p < 0.05). Plant lipid intake of the alcohol-smoking group was higher than those of alcohol-only group (p < 0.05) and the vitamin C intake of the alcohol-smoking group was lower than those of alcohol-only group (p < 0.05). With regard to the diet quality evaluation of subjects, the alcohol-smoking group showed significantly lower values than alcohol-only group in the nutrient density of carbohydrate, dietary fiber, sodium, potassium, vitamin B?, and vitamin C. Also, with regard to the index of nutrition quality (INQ) and the nutrient adequacy ratio (NAR), the alcohol-smoking group showed significantly lower value than alcohol-only group in vitamin C. With these results, we found that the alcohol-smoking group had lower diet quality evaluation. The results of blood analysis showed that HDL-cholesterol in the alcohol-smoking group was significantly lower than that in the alcohol-only group. In conclusion, the alcohol-smoking group had greater health risk than the alcohol-only group. Particularly, alcohol-smoking caused irregular eating patterns and unbalanced nutrition intakes compared to alcohol-only and also changed blood composition as shown in the decrease of HDL-cholesterol. Besides, the index of coronary heart disease such as AI was higher in both groups suggesting that alcohol-only or alcohol-smoking cause health problems. Since there is the limiting point in which the comparative analysis of non-drinkers and non-smokers is unable to be performed in this study, further wide research is needed on that matter.

N/A Researches on the characteristics of fatality-prone asthmatics have been performed in western countries, but there are few reports in this field in Korea. The purposes of this study were to clarify the magnitude of the problem and to identify the risk factors of near-fatal asthma(NFA). Methods : The records of patients admitted due to asthma attack were analyzed retrospectively. Results :1) The subjects had NFA in 50.6% and PaCO2 > 45mmHg in 22.9%. Five(11.1%) among NFA patients and 3 out of 19(15.8%) subjects with PaCO2 > 45mmHg required mechanical ventilation. 2) There were no significant differences between NFA and non-NFA in age, sex, resident place, academic career, familial and personal history of atopic diseases, serum total IgE level, positive skin prick test to house dust mites, accompanying allergic rhinitis and aspirin intolerance, emphysema on chest high resolution computerized tomogram, dyspnea perception, previous asthma education, regular OPD follow-up, and use of antiinflammatory drugs. 3) However, cigarette smoking(62.2% vs 38.6%), accompanying paranasal sinusitis(66.7% vs 45.3%), chronic asthma severity(severe persistent: 55.5% vs 29.5%), hospitalization frequency(2.93 vs 1.58), and duration of recent asthma exacerbation(6.6 vs 18.8 days) in NFA were significantly different from those in non-NFA.4) The relative risk for NFA was high in patients with history of hospitalization > 3, severe persistent asthma, exacerbation period < 3 days, smoking, or sinusitis in the order of frequency. Conclusion : Near-fatal asthma is a prevalent problem in clinical practice and asthma admission history, severe persistent asthma, short exacerbation period < 3 days, smoking, and paranasal sinusitis are the risk factors warning near-fatal asthma attack in advance.
