Recently, the occurrence and death rates of cancer have increased rapidly. In oriental medicine, the tongue gives some kind of special physiological information on human body. Oriental medical doctors have used information about the color, degree of wetness and shape of the patient's tongue to determine patient's disease and body condition. This fact leads us that the tongue image is one of the most important clinical data for helping doctor's decision making. It also has significant meaning to cancer patients related with traditional theory of oriental medicine. In diagnosis and treatment of cancer, tongue diagnosis can give some prognosis and change o cancer. It also detect the sign of early stage cancer, but it cannot diagnose the kind of cancer and/or benign or malignant. Nowadays BioTechnology(BT) has developed rapidly, but there are a lot of limits(economy, accuracy, clinical significance, etc). Tongue diagnosis is very economic and practical way of diagnose and has a lot of possibility of development. The need for doctors and it also helps the development of tongue diagnosis related with cancer.

Purpose: Children with celiac disease (CD) are at an increased risk of low bone mineral density (BMD) owing to malabsorption of fat-soluble vitamins, inflammation, and malnutrition. This study aimed to determine the prevalence and risk factors for low BMD in Iranian children with CD. Methods: This prospective cohort study examined 149 Iranian children with CD between 2011 and 2018 at Zabol University of Medical Sciences. BMD was measured using dual-energy X-ray absorptiometry. Demographic, clinical, and laboratory data were collected from patients' medical records. Logistic regression analysis was performed to identify the factors associated with low areal BMD (BMD-Z <-2) in the lumbar spine and femoral neck. Descriptive data were analyzed using the mean, standard deviation, and relative frequency. Data were analyzed using the chi-square test, t-test, and analysis of variance. Results: Of the 149 children with CD, 27.5% had osteoporosis. The mean body mass index (BMI) Z score was -1.28±1.2. Lower BMI was associated with a higher likelihood of BMD-Z (odds ratio 2.17; p≤0.05). Conclusion: Overall, the findings of this study showed that there was no correlation among Marsh classification, presence of specific human leukocyte antigens, and low BMD in Iranian children with CD. BMI can be a predictor of bone density in children with CD and may be applied clinically in early screenings to evaluate the bone health status in these children.

Objectives: This study was conducted to evaluate efficacy and safety of Punica granatum L. Actinidia chinensis Planch. mixed extract on body fat. Methods: Thirty women were recruited ($25kg/m^2{\leq}body$ mass index [BMI]${\leq}29.9kg/m^2$) ($19yr{\leq}age{\leq}38yr$) and randomized to receive Punica granatum L. Actinidia chinensis Planch. mixed extract or placebo for 8 weeks. During the test, they visited four times including screening. Body fat mass, body fat rate, anthropometric dimensions at waist and hip, waist-hip ratio, total cholesterol, triglyceride, low density lipoprotein-cholesterol (LDL-C), and high density lipoprotein-cholesterol (HDL-C) were measured at screening and 8 weeks after screening. Adverse reaction were also checked each visit. Results: There were no significant differences in all index. But when divide experimental group by BMI index, age, and compliance, less than BMI $27kg/m^2$ group decreased body weight, body fat mass and more than BMI $27kg/m^2$ group also decreased body weight, body fat mass and waist circumference. Less than age 30 years group showed decline of waist circumference, fat free rate and T-cholesterol and more than age 30 years group showed decline of fat free mass. Group with compliance more than 95% was decreased BMI, fat free mass, and hip circumference. Conclusions: There was no significant efficacy as compared with placebo group, but as divide experimental group according to BMI index, age, compliance, mixed extract might be effective to reduce obesity index.

Laparoscopic surgery is a surgical procedure which uses long laparoscopic instruments through tiny holes in abdomen while watching images from a laparoscopic camera through umbilicus. Laparoscopic surgeries have many advantages rather than open surgeries, however it is hard to learn the surgical skills for laparoscopic surgery. Recently, some virtual simulation systems for laparoscopic surgery are developed to train novice surgeons or resident surgeons. In this study, we introduce the techniques that we developed for laparoscopic surgical training simulator for cholecystectomy (gallbladder removal), which is one of the most frequently performed by laparoscopic surgery. The techniques for cholecystectomy simulation include modeling of human organs (liver, gallbladder, bile ducts, etc.), real-time deformable body calculation, realistic 3D visualization of surgical scene, high-fidelity haptic rendering and haptic device technology, and so on. We propose each simulation technique for the laparoscopic cholecystectomy procedures such as identifying cystic duct and cystic artery to clamp and cut, dissecting connective tissues between the gallbladder and liver. In this paper, we describe the techniques and discuss about the results of the proposed cholecystectomy simulation for laparoscopic surgical training.

피부는 인체의 외부를 덮고 있는 기관일 뿐 아니라, 체온을 조절하고, 감각기능을 수행하며, 약물을 투입하는 경로가 되기도 하고 내부 기관의 이상을 표현하는 기관이 되기도 한다. 이러한 이유로 인해, 사람들은 타인의 얼굴 피부의 상태를 보고 건강의 이상 징후를 감지하거나, "안색이 좋다", "생기가 있다" 등으로 신체의 컨디션을 표현해왔다. 환경과 노화정도에 따라서 피부색, 피부결, 수분, 탄력 등이 달라지는 것도 알려진 사실이다. 특히, 피부색은 아름다움, 매력도와 같은 주관적인 인상을 판단하는데 영향을 미치는 인자로 작용하는데, 화장품이나 피부시술을 통해 피부색을 개선하고자 하는 소비자를 통해서 그 수요를 짐작할 수 있다. 하지만 피부색이 여러 색의 구성임에도 불구하고, 대부분의 화장품이 하얀 피부로 개선해주는 것에 초점을 맞추고 있으며 여성들이 선호하는 피부색에 대한 연구가 아직까지는 미흡한 실정이다. 본 연구에서는 30 ~ 40대의 한국여성을 대상으로 같은 피부 밝기에서 붉은 정도와 푸른 정도가 달리 주어진 선호도 조사를 통해 긍정적으로 인식하는 피부색의 상태를 발견하였다. 한국여성은 실제 평균 피부색에 비해 붉은색과 푸른색이 높은 피부를 선호하는 것으로 나타났으며, 피부에 대한 표현을 달리하였을 때에도 경향은 유사하였다. 본 연구 결과는 새로운 소비자의 요구를 만족시키는 제품 개발에 활용될 수 있을 것이라고 생각한다.

Obesity provokes many serious human diseases, including various cardiovascular diseases and diabetes. Body mass index (BMI) is a highly heritable trait that is broadly used to diagnose obesity. To identify genetic loci associated with obesity in Asians, we conducted a genome-wide association study (GWAS) of a population of Korean adults (n=6,742, age 40~60 years) and detected six BMI risk loci (TNR, FAM124B, RGS12, NFE2L3, MC4R and FTO) having p< $1{\times}10^{-5}$. However, in the replication study, only melanocortin 4 receptor gene (MC4R) (rs9946888, p=$4.58{\times}10^{-7}$) was replicated with marginal significance (p<0.05) in the second cohort (n=5,102, age 40~60 years). This study indicates that each locus associated with BMI has very weak genetic effect.

In this study, we attempted to make an original pattern of clothing for an abnormal type of figure, especially for the type of kyphosis. We measured the curvature of the spine of a woman with kyphosis with a Martin measuring instrument and a silhouetter in the following ways. First, we counted the rate of shrinkage of the standard lines drawn on the surface of the body according as the body moved. Secondly, placing the front and back darts, the front and back shoulder darts and the side darts according to“Munhwa”pattern, we made cubic cuttings of four moving postures as well as the standing one. Thirdly, we superposed the developed patterns of the standing and the moving postures, measuring the position change and the amount to the change of the darts, and compared them. The results are as follows: 1) In the developed pattern of a cubic cutting of the basic pattern and the standing posture, the neckhole became larger than that of the basic pattern, and the waist line was lowered than that of the basic pattern because the center back line was shortened due to the curved backbone.

This study investigated the feasibility of gait recognition using points on the body in three-dimensional (3D) space based on comparisons of four different feature vectors. To obtain the point trajectories on the body in 3D, gait motion data were captured from 10 participants using a 3D motion capture system, and four shoes with different heel heights were used to study the effects of heel height on gait recognition. Finally, the recognition rates were compared using four methods and different heel heights.

This study examined the dieting behaviors and diet-influencing factors among college students in the Youngnam region. The data were collected by a self-administered questionnaires during May, 2007. One hundred-ninety samples were ultimately analyzed by SPSS Windows. The results were as follows. First, when comparing calculated BMI with perception of individual body image, many respondents regarded themselves as overweight although they were within normal BMI. Second, over four-fifths of the respondents indicated they were concerned with diet, and many respondents answered that they needed education and information on dieting. In terms of diet knowledge, the mean for correct answers was 77.9%. Mass media were very important sources for acquiring diet information, and the most popular dieting method was fasting therapy. The results of regression analyses to determine the factors affecting several dieting practices showed that grade, monthly allowances, diet awareness, diet knowledge, perception of individual body image, and BMI were significant.

The purpose of this study was to perform a kinematic analysis of Harai-goshi(hip throw) in superior female judo players. From our analysis, it appeared desirable for the player to shorten the duration of the technique for maximum results. It was also desirable for the player to draw the opponent backward while simultaneously maneuvering her close to her own body. A turning movement of the body toward the left side was found to be required for the technique, during which the player must lower the position of the center of gravity. During the subsequent angular change of the elbow, the player winds the elbow and, by moving the left shoulder, pulls the opponent toward her. The player lowers the body center by bending the left knee and letting the right knee extend, while turning the upper body and bending the hip joint. The player then draws the opponent in, contacts the opponent closely, turns, and stretches the right knee and hip joint rapidly and concisely, completing the move; it was also found to be desirable for the angular velocity to be increased for maximum efficacy.
