Objectives : The aim of this study was to analyze the symptoms of a disease and to elucidate the meaning and rationale of point selection in YuLongFu. Methods : We translated YuLongFu into Korean and analyzed symptoms based upon a comparison of YuLongFu with YuLongGe. The meaning and rationale of point selection in YuLongFu was then inferred from the analysis above. Results and Conclusions : Total 46 points (6 points were repeated) were used in YuLongFu. These points included the collateral Meridian, the four seas, five shu points, lower confluent points, yuan points and eight influential points. Moxibustion and pricking blood therapy were used twice. Generally, threre are a lot of diseases caused by stagnation of Qi and blood in YuLongFu. Point selection, therefore, was usually aimed at promoting flow of Qi and blood.

Objective : To increase the safety of moxibustion by understanding moxibustion-prohibited points' distinguishing features through literary inquiry. Method : We searched for moxibustion-prohibited points in Traditional Oriental Medical literature. Results : 1. Upon the advancement of moxibustion technique, the numbers of moxibustion-prohibited points increased. 2. Both Foot Meridians and Hand Meridians have similar percentage of moxibustion-prohibited points. Both Yin Meridians and Yang Meridians have similar percentage of moxibustion-prohibited points. 3. The face has the highest moxibustion-prohibited points ratio. The Back has the lowest moxibustion-prohibited points ratio. 4. We research 80 moxibustion-prohibited points and find 31 moxibustion-prohibitive reasons. A key reasons is that heating effect of moxibustion damages tissues, organs and meridian functions. There are also cases where the moxibustion-prohibited points can be designated upon the patients condition Conclusions : We could learn the distinguishing characteristics of moxibustion-prohibited points from this study. These results suggest that the treatment of moxibustion is more useful and safe.

Background and Purpose: Sybsun-points are located at the tips of all fingers, 0.1chon from the finger nails, totaling 10 points on both hands. These points have been used for emergency care, fainting, epilepsy, cerebrovascular accidents, hypertension, unconsciousness, high fever etc. The most common technique is bleeding with a needle at these points. Hypertension and fever are the main factors for stroke patients’progress. We investigated whether venesection at Sybsun-points has effects on blood pressure and body temperature in stroke patients. Materials and Methods: 79 stroke patients were enrolled in this study from 1 Jan. 1999 to 30 Sep. 1999. All of them were admitted in Kyunghee University, Hospital of Oriental Medicine. Among them, 62 patients were hypertensive people, 17 were normal. Among the hypertensive patients, 27 were stage 1,20 were stage 2, 15 were stage 3 by classification of JNC 1997. All of the hypertensive patients had been taking drugs, while the normal group did not. From 2pm to 3pm, every 30 minutes we checked patients' blood pressure and body temperature by 24ABPM and tympanic thermometer. After 30 minutes passed, we phlebotomized patients Sybsun-points with Samneung needle 2-3cc of blood. Right after the bleeding, we checked blood pressure and body temperature. After the bleeding, for the next hour and a half, we checked each patient’s blood pressure and body temperature every thirty minutes, or a total of three times. We compared the blood pressure and the body temperature before and after treatment(p<0.05). Results: 1. Venesection at Sybsun-points significantly decreased systolic blood pressure on stage 3 hypertensive patients(p<0.0l). 2. Venesection at Sybsun-points significantly decreased diastolic blood pressure on stage 3 hypertensive patients(p<0.05) 3. Venesection at Sybsun-points had no effect on the change of body temperature. Conclusions: Though further study is needed, our findings suggest that Venesection at Sybsun-points may alleviate hypertension in stroke patients.

Objectives: This study examined ways to promote desirable eating habits by choosing foods with low sugar contents and provide nutrition education in adolescents. Methods: This study was a cross-sectional survey. The sugar reduction perception and knowledge, sugary food preference, and intake frequency of 487 male and female high school students in Incheon were analyzed comparatively. Results: Approximately 94.9% and 94.5% of the subjects were unaware of the promotion of a sugar reduction policy and the sugar reduction in the basic guidelines for school meals, respectively. Approximately 95% of them had not received any sugar reduction nutrition education, and 90% were not interested in sugar reduction. The perception for sugar reduction was significantly higher in girls (3.43 out of 5 points) than in boys (3.16 out of 5 points) (P < 0.001). Knowledge about sugar was 3.65 out of 6 points in girls and 3.04 points in boys (P < 0.001). The preference and intake frequency for fruits of the total students were 4.24 out of 5 points and 2.56, respectively. For beverages, the preference was significantly higher in boys (3.97 points) than in girls (3.70 points) (P < 0.001), and the intake frequency was significantly higher in boys (2.26 points) than in girls (2.08 points) (P < 0.001). The preference for snacks was significantly higher for girls (4.19 points) than boys (4.02 points) (P < 0.01), and the intake frequency was 2.22 points in boys and 2.17 in girls, showing no significant difference. Sugar reduction perception and knowledge about sugar showed significant negative correlations with the snack intake frequency (r = -0.11, P < 0.05; -0.13, P < 0.05) after adjusting for gender, grade, and body mass index. Conclusions: The high school students' perception of sugar reduction was very low, and there was a significant correlation with sugary food intake, suggesting that the sugary food intake will decrease as the sugar reduction perception and knowledge about sugar increase.

In this research, we measured the number of lanes, distance, disposition of apartment that are affecting the road traffic noise to evaluate the current condition of G city's road traffic noise. We decide on a basis regarding an apartment price formation factor, and the apartment current price and the results that compared. To have a point scale, we set the maximum road traffic noise at a 8 lane road for 5 points, give 4 points for a 6 lane road, which has a $2.1{\sim}2.5\;dB(A)$ difference compared to a 8 lane road, give 3 points for a 4 lane road, which has a $5.2{\sim}5.5\;dB(A)$ difference compared to a 8 lane road, and set 2 points for a 2 lane road and lower. If we set the standard floor plan as horizontal and a living room facing the roadside, the horizontal and living room facing the opposite side of the road is 1 point because it differs by 14.1 dB(A), and the vertical is 3 points since the difference is 5.3 dB(A). If we make grades by the distance, making standard the fifth floor with little soundproof effect from apartment to road, we observe a measurement below 2.9 dB(A) at a distance of less than 10 m and 5 dB(A), decreased at a distance of 20 m. Therefore, 4 points were given for less than 10m, 3 points for $10{\sim}20\;m$, 2 points for more than 20 m as we can apply the effect of a decay distance of line sound source and the decrease in noise effects of more than 6 dB(A), 1 point for more than 40m, and 0 points for more that 80 m since it is negligible. 28 apartments got 0 points because there is no effect of road traffic noise from other apartments, and 50 apartments where only the road at one side effect them got $5{\sim}10$ points. 4 apartments (17-2, 6-3, 10-4, 3-3) received over 20 points. 15 cases showed a difference between developer price and resale price, and 11 cases (73%) among them showed the same trend (price increases with a low road traffic noise restriction factor point) with the point of road traffic noise restriction factor. 4 cases demonstrated the opposite trend, showing price increases with a high restriction factor point. Among the 4 cases, case numbers 2,6 and 9 appear to be more affected by the location factor (business district) than the road traffic noise restriction factor, and case number 1 appears to be affected by the building factor (openness and direction).

Objectives : Acupoints are divided into three categories: classical acupoints, extra-acupoints, and Ashi points. The aim of this study was to understand the meaning and features of Ashi points. Methods : We examined the original meaning of Ashi points from the classical medical texts, including the Beijiqianjinyaofang, the Essential Prescriptions Worth a Thousand Gold for Emergencies, and the Huangdi Neijing, the Yellow Emperor's Canon of Internal Medicine. Results : First, the Ashi method is to locate the points for the acupuncture and moxibustion based on the patients' reactions mainly manifested by sensations of comfort and pain, which can help identify not only Ashi points but also classical and extra-acupoints. Thus, Ashi points may or may not match to classical or extra-acupoints, and we propose that Ashi points should not be classified mutually exclusive to classical or extra-acupoints. Second, there are several similarities between Ashi points and myofascial trigger points. They are located by palpation and have no fixed anatomical positions. Patients experience painful but pleasant feeling when Ashi and myofascial trigger points are pressed, and stimulation of these points have treatment effects. Conclusions : We suggest that Ashi method be used to identify the acupoints based on how patients react when these points are pressed. Ashi points may or may not correspond to classical or extra-acupoints, and share traits with myofascial trigger points.

It is interesting to locate homogeneous segments within a DNA sequence. Suppose that the DNA sequence has segments within which the observations follow the same residue frequency distribution, and between which observations have different distributions. In this setting, change points correspond to the end points of these segments. This article explores the use of a binary segmentation procedure in detecting the change points in the DNA sequence. The change points are determined using a sequence of nested hypothesis tests of whether a change point exists. At each test, we compare no change-point model with a single change-point model by using the Bayesian information criterion. Thus, the method circumvents the computational complexity one would normally face in problems with an unknown number of change points. We illustrate the procedure by analyzing the genome of the bacteriophage lambda.

Singular points are those at which the determinant of a Jacobian matrix is zero. A parallel manipulator gains mostly an extra DOF at the singular points, where it can not be properly controlled. In this study, singular points of a cubic parallel manipulator are illustrated by obtaining the determinant of a Jacobian matrix mathematically, and the singular points of the manipulator are found to be three separate planes in a 3D space. The dependency among links for each singular point is determined by applying linear algebra. Also, the singular points and workspace of the cubic parallel manipulator are plotted to check if the workspace contain singular points.

This study was to select the measurement points for the brassier and the waist-nipper. 15 subjects (ages 30-40) were chosen by % body fat to represent various physical types. Subjects put on each garment, brassier and a waist-nipper, in turns. Measurement points in the underwear were selected according to the parts of human body. The characteristics and surface area of each garment was considered carefully when the measurement points were selected. Selected measurement points on a brassier and a waist-nipper were chosen from the anterior midsagittal line, the side-seam line, and the posterior midsagittal line. Three points on the brassier and three points on the waist-nipper were selected as the measurement points. There was a highly significant correlation between % body fat and mean garment pressure. There were no significant relationships between thickness of subcutaneous fat and mean garment pressure by measured parts.
