강우량의 시간분포 특성에 관한 강우상태 분석은 소유역의 계획홍수량을 결정한다거나 도시지역의 배수망 설계를 위한 설계유량 산정을 위하여 대단히 중요하다. 서울 지역의 과거 기록치로부터 총강우량이 20mm 이상 되는 약 400개의 호우자료를 이용하여 5분간격 강우의 시간분포를 해석하였다. 총강우량에 대한 백분율을 총강우시간에 대한 백분율과 연관시키고 획득된 자료를 강우 최대치가 발생되는 위치 따라 4개의 그룹으로 분류 분석하여 그 결과를 제시하였다. 또한 강우와 강우간의 변화성을 정량적으로 나타내기 위하여 시간분포 특성을 빈도 확률에 따라 분석하였다. 분석결과로 얻어진 강우의 시간분포 관계는 설계유량 수문곡선 결정에 사용되는 설계강우의 우량주상도를 얻는데 사용될 뿐만 아니라 주어진 유역에서의 강우형상을 파악하는데 적용될 수 있다. 또한 수문해석 문제를 위한 강우의 모델을 형성할 수 있으며 공간적 분포 이외의 강우특성 및 매개변수 등과 같은 자료와 연관시킬 수 있다. 분석결과 제2구간 강우의 빈도가 가장 높았으며 제4구간 강우의 빈도가 가장 낮았다. 이와 같은 분석 결과인 시간분포의 특성을 누가 강우시간 백분율과 누가 강우량 백분율의 항으로써 확률별로 표시하였으며 각 구간별 강우의 시간분포 양상 및 그에 따른 우량주상도를 도표화하였다.

TyG (triglyceride and glucose) index using triglyceride and fasting blood glucose is recommended as a useful marker for insulin resistance. The present study evaluated the usefulness of TyG index in diagnosing metabolic syndrome and suggested an optimal cut-off value. The subjects of this study were adult 4,415 adults aged 20 to 80 years who underwent health screening at J General Hospital from January 2016 to January 2017. Metabolic syndrome was based on AHA/NHLBI (American Heart Association/National Heart, Lung, and Blood Institute) criteria. TyG index correlated with metabolic syndrome risk factors including HOMA-IR. Compared with the participants in the lowest quartile of TyG index, odds ratios and 95% confidence intervals for metabolic syndrome were 8.5 (3.005~23.903), 20.0 (17.190~23.407) for those in the third, and the fourth quartile of TyG index. The optimal cut-off value of the metabolic syndrome was 8.81 for TyG index (sensitivity 86.7%, specificity 80.1%) and area under the ROC curve (AUC) was 0.894. In conclusion, TyG index is effective to identify individuals at risk for metabolic syndrome.

In experiment 1, dietary self-selection of the 3 macronutrients, protein, fat, and carbohydrate were examined in male rats given 3 food cups of 80% carbohydrate, 80% protein, and 70% fat diets simultaneously. All the rats showed normal growth pattern and organ weight, which means they have ability to select just right kinds and amounts of nurients in order to support their growth and development. Mean values of caloric intake, body weight gain, serum lipid values and empty carcass compositions were not significantly differ between the upper and lower quartile groups of fat proportion of empty carcass compared to the lower quartile group(LF). Same feeding design was employed in experiment 2 where the effect of mild electric stress on food selection was studied. The rats in both control and electric stress group revealed a normal growth curve and organ weights. The rats in both control and electric stress group revealed a normal growth curve and organ weights. The stress group showed higher caloric intake and body weight gain than control group, but no significant effects of stress on serum and empty carcass components was found. Even though normal rats seemed to select macronutrients according to their physiolosical needs, there were individual differences in food selection whether they were exposed to stress or not. Therefore life long individual food selection pattern may have a great influence on nutritional status and chronic degenerative diseases of eldery, and on aging process.

본 연구에서는 분포를 알 수 없고 비대칭인 공정자료에 실용적으로 적용할 수 있는 간단한 관리도법을 제안하였다. 비대칭 분포를 따르는 공정자료에 정규성 가정에 기초한 슈하르트 관리도를 그대로 적용하면 비대칭성이 증가할수록 제 1종 오류를 범할 확률이 증가할 가능성이 높아지며 변동을 관리하는데 효율성이 떨어지게 된다. 이러한 문제를 해결하기 위해 본 연구에서 제시한 관리도는 관리한계선을 사분위수에 기초하여 정하는 방안을 제시하고 있다. 이러한 방법으로 관리한계선을 그릴 경우 제 1종 오류도 감소하게 되고, 비대칭분포를 하는 공정자료에 대하여 매우 실용적이라고 하겠다.

Background: The role of processed meat in the aetiology of squamous cell oesophageal cancer has been explored in detail. Methods: In the time period 1990-2005, a case-control study was conducted in Montevideo, Uruguay including 2,368 participants (876 cases of oesophageal cancer and 1,492 controls). Relative risks, approximated by the odds ratios, were estimated by multiple unconditional logistic regression. Results: Processed meat was positively associated with oesophageal cancer (upper quartile vs lower quartile OR 2.30, 95%CI 1.72-3.07), whereas salted meat intake was positively associated with squamous cell oesophageal cancer (OR 3.82, 95%CI 2.74-5.33). Finally other cured meats were positively associated with oesophageal cancer (OR 1.65, 95%CI 1.22-2.22). Conclusions: It could be concluded that processed meat consumption could be an important risk factor for the aetiology of squamous cell oesophageal cancer in Uruguay.

It has been reported that the increased uric acid level is associated with metabolic syndrome risk factors in both male and female. However, there has not been enough studies to investigate gender differences of this association in Korea. To evaluate relation between serum uric acids and metabolic syndrome markers, anthropometric and biochemical analyses data was obtained from National Health Examination 2005 and 5,523 (M=3,097; F=2,426) data was analyzed. Results by quartile of serum uric acid levels in females showed that increased serum uric acid level was associated with elevated levels of total-. LDL-cholesterol, and triglycerides, whereas association between serum uric acid and total cholesterol levels was not observed in male subjects. In both female and male, higher quartile of serum uric acid level were linked with lower levels of HDL-cholesterol. In regression analysis, association of serum uric acid levels with fasting glucose levels was significant in female subjects only. In conclusion, higher serum uric acid levels were associated with metabolic syndrome indices, however gender differences were existed for total cholesterol.
