Introduction: Dyslipidaemia is directly associated with cardiovascular diseases. Temperament, the unique constitutional make-up of an individual, is responsible for one's personality traits, physical appearances, and disease predispositions. The rising prevalence of dyslipidaemia becomes a challenge to control morbidity and mortality due to cardiovascular diseases. Objective: To study clinical patterns and risk factors of dyslipidaemia and its association with temperament at the individual level was the main objective of this study. Materials and Methods: It was a descriptive and analytical cross sectional study. The participants (n=88) were screened on the basis of raised serum lipid profile from the outpatient department of National Research Institute of Unani Medicine for Skin Disorders, Hyderabad. The data were collected on a case record form designed for this study and analyzed retrospectively. Results: In this study, there were 57% participants (n=50) of phlegmatic temperament in which mean total cholesterol, triglycerides, low density lipoprotein- cholesterol and high density lipoprotein-cholesterol were 230.92 (±49.48) mg/dl, 182.34 (±110.61) mg/dl, 153.24 (±50.21) mg/dl and 46.3 (±10.83) mg/dl respectively. Discussion: This study showed the prevalence of different clinical patterns of dyslipidaemia in the population and the phlegmatic participants were dyslipidaemic in a higher percentage. The prevalence of dyslipidaemia in phlegmatic participants may be linked to the constitutional make-up of the individual. The temperament of an individual may be considered as one of the risk factors for dyslipidaemia. Conclusion: It was concluded that the temperament of an individual may be used as a screening tool to predict the individual's tendency to develop dyslipidaemia.

이 논문은 국내 대학교의 영화 관련학과에서 실행하는 영화언어에 관한 기초 교육 사례로서, 성결대학교 영화영상전공에서 실제로 시행된 수업을 토대로 제안되었다. 이 수업은 감상을 우선시하면서 이를 바로 실습과 연계시키는 방법으로 진행하였으며, 한 학기 수업 내용을 모두 다룰 수 없는 관계로 본 연구에서는 사운드와 카메라 활용 내용에 초점을 맞추었다. 사운드는 작은 카메라를 가지고 촬영과 동시에 나레이션을 말하는 방식과 마이크를 활용하여 사운드의 원근법적 '청점(聽點)'을 경험해볼 수 있도록 하였다. 카메라의 경우, 다양한 카메라 움직임을 직접 시연해 볼 수 있도록 하였다. 직접 카메라를 들고 움직임을 부여하는 핸드헬드 테크닉을 이용해서 트랙킹이나 크레인에 상응하는 효과를 내는 방법으로 유희적인 제작 방식을 유도하였다. 또한 '카메라와 놀기'라는 활동을 통해 영화를 사적인 매체로 발전시킬 수 있는 상상력을 유발 시키고자 하였다. 그리고 이런 방식의 제작과정을 고려하면서 가장 적합한 모델을 제시하기 위해 해당 양식이 사용된 영화의 클립을 감상하도록 하였다.

Obejectives : The purpose of this study was to investigate the effects of Yijin-tang on pacemaker potentials of small intestinal interstitial Cells of Cajal (ICC). Methods : To dissociate the ICC, we used enzymatic digestions from the small intestine in mice. The electrophysiological whole-cell patch-clamp configuration was used to record pacemaker potentials in the cultured ICC and the in vivo effects of Yijin-tang on GI motility were investigated by calculating percent intestinal transit rates (ITR). Results : 1. The ICC generated pacemaker potentials in the murine small intestine. Yijin-tang produced membrane depolarization with concentration-dependent manners in the current clamp mode. 2. Pretreatment with a Ca²⁺ free solution and thapsigargin, a Ca²⁺-ATPase inhibitor in the endoplasmic reticulum, stopped the pacemaker potentials. In the case of Ca²⁺-free solutions and thapsigargin, Yijin-tang did not induce membrane potential depolarizations. 3. U73122, a phospholipase C (PLC) inhibitors, blocked the Yijin-tang-induced membrane potential depolarizations. However, U73343, an inactive PLC inhibitors, did not block. 4. In the presence of protein kinase C (PKC) inhibitors, staurosporine or Rottlerin, Yijin-tang depolarized the pacemaker potentials. However, in the presence of Go6976, Yijin-tang did not depolarize the pacemaker potentials. 5. In mice, intestinal transit rate (ITR) values were significantly and dose-dependently increased by the intragastric administration of Yijin-tang. Conclusions : These results suggest that Yijin-tang can modulate the pacemaker activity of ICC through an internal/external Ca²⁺ and PLC/PKC-dependent pathway in ICC. In addition, Yijin-tang is a good candidate for the development of a prokinetic agent.

Background: Association of angiotensin converting enzyme (ACE) gene polymorphisms with lung cancer susceptibility remains uncertain and varies with ethnicity. Northeast India represents a geographically, culturally, and ethnically isolated population. The area reports an especially high rate of tobacco usage in a variety of ways of consumption, compared with the rest of the Indian population. Materials and Methods: We conducted a population based case control study in two major high risk region for lung cancer from Northeast India. A total of 151 consecutive lung cancer cases diagnosed histopathologically and equal numbers of controls were recruited with record of relevant sociodemographic information. Blood samples were collected and processed to identify ACE gene polymorphism. Results: Significantly higher (40.4 % vs 29.1%, OR=1.97, CI=1.04-3.72; p=0.037) prevalence of the ACE II genotype was observed among lung cancer cases. Smoking was significantly associated with increased risk of lung cancer (OR=1.70, CI=1.02-2.81; p=0.041). An enhanced risk was also observed for interaction of ACE II genotype with tobacco smoking (OR=4.09, CI=1.51-11.05; p=0.005) and chewing (OR=3.68, CI=1.22-11.13; p=0.021). Conclusions: The present study indicates significant association s of the ACE II genotype with lung cancer in high risk Northeast India.

Forest fire is a critical disaster that causes massive destruction of forest ecosystem and economic loss. Hence, accurate estimation of the burned area is important for evaluation of the degree of damage and for preparing baseline data for recovery. Since most of the area size damaged by wildfires in Korea is less than 1 ha, it is necessary to use satellite or drone images with a resolution of less than 10m for detecting the damage area. This paper aims to detect wildfire-damaged area from a Kompsat-3 image using the indices such as NDVI (normalized difference vegetation index) and FBI (fire burn index) and to examine the classification characteristics according to the methods such as Otsu thresholding and ISODATA(iterative self-organizing data analysis technique). To mitigate the salt-and-pepper phenomenon of the pixel-based classification, a gaussian filter was applied to the images of NDVI and FBI. Otsu thresholding and ISODATA could distinguish the burned forest from normal forest appropriately, and the salt-and-pepper phenomenon at the boundaries of burned forest was reduced by the gaussian filter. The result from ISODATA with gaussian filter using NDVI was closest to the official record of damage area (56.9 ha) published by the Korea Forest Service. Unlike Otsu thresholding for binary classification,since the ISODATA categorizes the images into multiple classes such as(1)severely burned area, (2) moderately burned area, (3) mixture of burned and unburned areas, and (4) unburned area, the characteristics of the boundaries consisting of burned and normal forests can be better expressed. It is expected that our approach can be utilized for the high-resolution images obtained from other satellites and drones.
