  • This study aimed to determine the effects of the blockage of visual feedback on joint dynamics of the lower extremity. Fifteen healthy male subjects(age: $24.1{\pm}2.3\;yr$, height: $178.7{\pm}5.2\;cm$, weight: $73.6{\pm}6.6\;kg$) participated in this study. Each subject performed single-legged landing from a 45 cm-platform with the eyes open or closed. During the landing performance, three-dimensional kinematics of the lower extremity and ground reaction force(GRF) were recorded using a 8 infrared camera motion analysis system (Vicon MX-F20, Oxford Metric Ltd, Oxford, UK) with a force platform(ORG-6, AMTI, Watertown, MA). The results showed that at 50 ms prior to foot contact and at the time of foot contact, ankle plantar-flexion angle was smaller(p<.05) but the knee joint valgus and the hip flexion angles were greater with the eyes closed as compared to with the eyes open(p<.05). An increase in anterior GRF was observed during single-legged landing with the eyes closed as compared to with the eyes open(p<.05). Time to peak GRF in the medial, vertical and posterior directions occurred significantly earlier when the eyes were closed as compared to when the eyes were open(p<.05). Landing with the eyes closed resulted in a higher peak vertical loading rate(p<.05). In addition, the shock-absorbing power decreased at the ankle joint(p<.05) but increased at the hip joints when landing with the eyes closed(p<.05). When the eyes were closed, landing could be characterized by a less plantarflexed ankle joint and more flexed hip joint, with a faster time to peak GRF. These results imply that subjects are able to adapt the control of landing to different feedback conditions. Therefore, we suggest that training programs be introduced to reduce these injury risk factors.

  • This study provides some basic information on the improvement of diabetics' self-care activities through examining the patients' knowledge on diabetes, self-care activities, and how much they feel those activities are effective and through studying the correlation among the three factors. One hundred and fifty four patients were subjected to this study, who were treated or hospitalized in a hospital in Pusan. Researches were conducted from October 21 to November 9, 2002, and information were gathered by questionnaire and direct conversation with the patients. The data was processed through SPSS WIN 10.0 program. The Date were analyzed by descriptive statistics, ANOVA, t-test, Pearson correlation coefficient and Spearman rank correlation coefficient. The results of this study was the followings; 1) The subjects' knowledge on diabetes ranged from 6 to 23 points with a mean of 17.01 points. 2) The subjects' self-care activities ranged from 21 to 103 points with a mean of 67.72 points. That of the patients with regular treatments appeared to have the highest points (3.51) and the lowest points appeared in the measurement of sugar level in blood (2.60) 3) The subjects' feelings of effectiveness ranged from 21 to 103 points with a mean of 70.01 points. Drug therapy had the highest point (3.94) and diet showed the lowest (3.37) 4) In the general characteristics of the subjects, the more education a subject had, the more knowledge on diabetes he or she appeared to have (F=3.36, p=0.012). The self-care activities were significantly high among non-alcoholic subjects (F=4.301. p=.016). The subjects' feelings of effectiveness were higher in female patients than in male patients(t=2.132 , p=.035), and those in the ages between 51 and 60 felt more effectiveness (F=4.198. p=.003). In addition, married subjects felt more effectiveness than the unmarried (t=2.856, p=0.005), and the more education a patient had. the more effectivess he or she felt (F=2.879, p=.025). 5) In the subjects' pathological characteristic, the subjects who experienced diabetes education showed more knowledge on diabetes, more self-care activity, and more effectiveness than those without the education (t=3.193, p=.002; t=2.299, p=.023; t=2.128, p=.035). 6) As the results of the analyses of correlations among knowledge on diabetes, self-care activity, and effectiveness, the more knowledge on diabetes a patient had, the more self-care activity and the more effectiveness he or she showed (p=0.283. p=0.002; p=0.182, p=0.036). Self-care activity became higher as the feeling of effectiveness appeared higher (r=.550, p=.000). Based on the results above, several suggestions were made; 1) This study was conducted in one hospital, so it is difficult to generalize the results. It is necessary to gather more information from more patients through repeated researches. 2) The study on the other factors which can affect a patient's self-care activity is required. 3) The development of a program which improves a patient's self-care activity, knowledge on diabetes. and effectiveness is needed.

  • For understanding of anatomy, physiology, and diseases of human TMJ, it is required to evaluate quantitatively the movement of the disc and condyle head of mandible. The histologic section of cadaver TMJ were examined, and the magnification of the MR image and its details of anatomy were evaluated. And then a quantitative analytic method, by comparing the Sectograph and the MR image of vital human TMJ, was proposed. For this study, 15 subjects(Male, 24~35years) were selected from a prosthodontic examination randomly, and each subject’s five interocclusal rubber registration records were made on the ICP, and 5, 10, 15, and 20mmjaw opening positions. All subjects were radiographed with a Denar Quint Sectograph Image System(Denar Corp., USA), and imaged with a MRP-20EX MR Image System(0.2T, Permanent Magnet Type, Hitachi Medical Corp., Japan) using an 100mm diameter bilateral type surface coil. These images were traced on the acetate tracing paper, and analyzed In this study, the findings led to the following conclusions. 1. In comparison of the histologic section of autopsy specimen with the MR image at the same section, the size(dimension) of MR image was 70% of the real one. It was possible to recognize the shape of articular disc, anterior and posterior attachments, and adjacent soft tissues, because of the excellent reproducibility of anatomical structure. 2. When we compared the amount of joint space on MR image with that of joint space on sectograph, the amount of joint space on sectograph was significantly greater than that of joint space on MR image, except at the top of condylar head. 3. The position of minimum joint space on sectograph at intercuspal position didn't coincide with the middle position of articular disc on MR image, and was approximately in the anterior third of posterior band of articular disc. 4. The amount of condylar movement on MR image at opening movement was greater than that of articular disc movement. From Intercuspal position to 5mm jaw-opening movement, the condylar movement showed hinge one, and over the range 5mm jaw-opening it suggested hinge & translatory one. 5. In terms of area variation of articular disc measured on MR image in sagittal plane, the area of posterior band increased with increasing the amount of Jaw opening, but the area of anterior band decreased conversely.

  • Protein malnutrition of children is one of the most serious nutritional deficiencies in developing country. Urea nitrogen excretion in ureotelic animals is the function most sensitive to dietary protein. The 24 hours excretion of creatinine in the urine of a given subject is remarkably constant from day to day. The creatinine excretion of different individuals of the same age and sex is also quite constant. Low ratios of urinary urea to creatinine are found children low protein intake. The foregiving world-wide investigations indicate that the urea nitrogen/creatinine ratios seems to be a good biochemical indicator to distinguish among group with different levels of protein intake. The purpose of this study is to evluate an indicator of protein intake on the elementary school children ranged from 6 to 8 years of age living in rural and urban areas. Each child measured for height and weight of body. weight measured by means of a plate from scale and height by a vertical measuring rod. Biochemical test were taken from a finger-tip and urine. Hemoglobin level in the blood was measured by cyanomethemoglobin method. From the urine samples, urea nitrogen and urea creatinie were determined by Folin-Wu method and: calculate the ratio. The following result were obtained: 1) Mean of the body weight and height in urban children(Seoul) was higher and heavier than rural children(Kyunggi, Kangwon). And 12% of boys, 18% of girls in Kyunggi and 25% of boys, 22% of girls in Kangwon area weight less than 80% of Korean Physical Standard weight level. 2) The mean hemoglobin values of boys and girls in Seoul are children were 13. 3g/100ml, 13.1g/100ml and the mean of hemoglobin values in Kyunggi 12.9g/100ml of boys, 12.4g/100ml of girls, and 12.4g/100ml of boys, 12.9g/100ml of girls in Kangwon children. It is found that 22% to 24% children inrural area (Kyunggi, Kangwon) had hemoglobin level less than 12g/100ml which means anemia. 3) The mean of hematocrit level of Seoul, boys and girls children were 33.5%, 34.1% and 33.4%, 33.1%, in Kyunggi area and 33.1%, 32.9% in Kangwon area. 4) Urea nitrogen/creatinine ratios in Seoul children were 9. 0, 10. 0 of boys and girls, the ratio were 8.2, 8.0 in Kyunggi boys and girls children, and 7.5 and 7.4 in Kangwon boys, girls children. Low-income rural and upper-income urban background large differences between two groups in the urea nitrogen/creatinine ratio(Seoul: Kangwon in male, female children. p<0.05, p<0.001). The urea nitrogen/creatinine ratio definetly seems to be a good indicator of the quantity of the protein intake. However, whether or not it is an indicator of the quality of the ingested protein ramains to be seen.

  • Objective : The aim of this study was to analyse the latest trend of medical science articles about Bojungikki-Tang published in Japan. Methods : We searched medical science articles published from 2003 to 2008 in Japan on the web site, CiNii and then these articles were reviewed and classified according to experimental subject and method. Results : Fifty-two articles, related to Bojungikki-Tang were searched and these were classified into three classes, pharmacological signaling studies, clinical case studies and the others. As a result of classification, clinical case studies were most abundant by 38 cases, pharmacological signaling studies were 10 and the others were 4. This result suggested that the study of Bojungikki-Tang was mainly focused on clinical study rather than experimental study. Among the clinical case studies, clinical studies related to immune disease took the most greatest number and number of other clinical studies were evenly distributed over the various disease. Immune intensification effect of Bojungikki-Tang can be thought continuous with reinforce the middle Jiao Qi in company with improvement effect on growth hormone failure and male infertility. A fact that the one prescription, Bojungikki-Tang could be used to treat various diseases reflects a viewpoint of Oriental medicine that is based on the respect for and understanding of individual constitution and disposition while paying attention to the gender difference and individuality. The clinical usefulness of Bojungikki-Tang on obstructive sleep apnea syndrome and visceroptosis concerns with ascend Yang and treat Qi sinking. Pharmacological signaling studies were mainly focused on diseases that were treated Bojungikki-Tang in clinic, however, there was one study that experimented on changes of numerous gene expression according to the treatment of Bojungikki-Tang using DNA array. Conclusion : The therapeutic system of Oriental medicine is different in various aspects form that of Western medicine and appropriate harmonization of east and west is expected to improve the quality of medical care. In this regard, continuous investigation and analysis about herbal medical science papers in Japan can also be useful to make progress in Korean traditional medicine.

  • This study examined the reproducibility of nutrient intakes estimated by the 24-hour recall method in a prospective cohort study (Longitudinal study of aging and health monitoring of Korean elderly) of middle-aged volunteer subjects (42 males and 49 females) in the Seoul area. The three-day 24-hour recall was administered twice at an interval of approximately 6 months. The first data were collected and a corrective procedure was performed by interviewing of the subjects and a trained dietitian. The second data were collected by mail from the subjects without the performance of any corrective procedure. The mean age of the subjects was 53.5 $\pm$ 9.6 for the males and 52.2 $\pm$ 8.9 for the females. The subjects who had above college education were 95% in the case of the males and 60% in the case of the females. The characteristics of the male subjects in this study were that they were highly educated and held professional jobs and were from the middle or upper class. Comparing the first and second 24-hour recall data, the second data showed relatively lower intakes of all nutrients, except vitamin A, vitamin Bi and cholesterol. There was no difference in the nutrients of the first and the second data with respect to vitamin A, vitamin B$_1$ and cholesterol in the males and calcium, iron, sodium, vitamin A, vitamin B$_1$, vitamin B$_2$ and cholesterol in the females. This data may indicate that the 24 hour retail method without a dietitian's help may result in lower reporting of the subject's intakes. The men had a tendency to remember less than the women. Pearson's correlation coefficients with unadjusted nutrient intakes values were ranged from 0.24 to 0.66. When energy intake was adjusted, there was a slight increase (from 0.26 to 0.71). Intra-class correlation coefficients with nutrient-unadjusted values ranged from 0.22 to 0.66, and the energy-adjusted values were ranged from 0.23 to 0.69. The weighted Kappa statistical values ranged from 0.10 to 0.40. On the average,46.3% of the subjects who were found in the lowest quartile of the nutrient intake levels based on the first 24-hour recall, were in the lowest quartile based on the second 24-hour recall. Therefore, there was a low reproducibility between the first and the second 24-hour recall. We should examine the factors influencing low reproducibility. Also, strategies should be developed to maximize the reliability of the assessment, with regard to portion-size training and telephone validation. (Korean J Community Nutrition 8(4) : 603∼609, 2003)
