through a literal study upon Arrhythmia between east and west medicine, the results were as follows 1. Arrhythmia is not only irregular cardiac beat but disorder of cardiac impulse making and conduction disturbance. it means almost irregularity of interval between two beat 2. In the east medicine, arrhythmia is represented various category as palpitation, continuous palpitation, dizziness, consumption which give the first consideration by the accompanied symptoms. A separate way in a diagnostics it become a base of diagnosis of diseases and decision of prognosis by the examination of pulse 3. In the west medicine, Arrhythmia is classified as disorder of heart rate, rhythm, conduction disturbance or tachycardia, bradycardia and it is concomitant with fatigue, palpitation, dyspnoea, syncope, chest discomfort 4. The diagnostic study of pulse condition which represent arrhythmia was started from $\mathbb{<}$Nae-Kyung$\mathbb{>}$ and it was revealed as pulse condition of rapid pulse, slow pulse, swift pulse, running pulse, knotted pulse, intermittent pulse etc. Out of them running pulse, knotted pulse, intermittent pulse which obviously are concomitant with irregularity of interval are clinically meaningful in a conditions of disease and decision of prognosis. and the significance of these pulse condition are transformed through the changes of the times 5. According to cause of disease it is classified by Arrhythmia(running pulse, knotted pulse, intermittent pulse) due to heat, cold, phlegm, deficiency(or insufficiency) and There are three categories of etiological factor that is, endogenous, exogenous and non-exo-endogenous factor. the endogenous factor is insufficiency of the heart Ki, deficiency of both Ki and blood, intemal stagnation of phlegm and fluid, stagnation of seven emotions. the exogenous factor is caused by stagnation of Ki and blood by six exogenous pathogenic factor and the non-exo-endgenous factors are improper diet, overstrain, traumatic injury. A cause of arrhythmia in western medicine are a organic and pathological change of the heart itself and malfunction of the autonomic nervous system.

The purpose of this study is to understand the sliding characteristics of the infilling-joint surface using the new devised shear test apparatus with changeable slope for the original infilling materials and the infilling materials experienced cyclic freezing-thawing processes. Three types of the mother rock classified as the igneous rock, the metamorphic rock and the sedimentary rock and the infilling materials were collected for laboratory test. The cohesion according to the slope change of the rock joint shows large variation within ${\pm}$5 degrees but the internal friction angle shows appears the linear decreasing tendency. It is confirmed that the affecting factor of slope change of rock joint at the behavior of rock mass is larger than that of the infilling thickness. Test results show that the cohesion and the internal friction angle in 100 times of cyclic freezing-thawing processes are decreased about 50 percent compared with original one. A further study using various infillings materials would lead to a better understanding of the failure mechanism of rock mass by slope change of rock joint.

This study describes the application of the stages of change construct to fat intake by examining the associations of the stages of change with nutritional status and beliefs on health behavior. Data were obtained from apparently healthy 596 adults(326 females and 270 males) residing in large cities. Stages of change assessed by an algorithms based on 6 items were designed each subject into one of the 5 stages: precontemplation(PC), contemplation(CO), preparation(PR), action(AC) and maintenance(MA). Beliefs on health behavior were assessed by self efficacy as well as 4 belief scales from the Locus of Illness Control(LIC) developed using factor analysis such as internal disease cure and prevention and external disease cure and prevention. Energy and fat intakes were measured by a 39 item short form food frequency questionnaire. Regarding the 5 stages of change, MA stage comprised the largest group(37.9%), followed by Ac(30.7%), PC(11.4%), CO(10.4%) and PR(9.6%). Subjects who were females, older or healthier were more likely to belong to either AC or MA. Stage assignment of individuals was corroborated by their nutritional variables. Those in PC had the most energy and fat and those in MA ate the least for females. BMI was higher in PR than any other stages for both males and females. Those in PC were distinctive in that they were more externally oriented in terms of health control showing higher scores on external disease prevention(for males) and external disease cure(for females), and lower score on internal disease cure. On the other hand, those in MA received the highest scores on internal disease prevention and self efficacy, which suggested that they were more internally oriented. Canonical discriminant function analysis indicated that the 5 stages were importantly discriminated by BMI, self efficacy, internal disease prevention and external disease prevention for males and by fat intake, self efficacy and external disease cure variables for females. The results of our study confirm differences in stages of change in fat intake in terms of nutritional status and beliefs on heath behavior and indicate the need for taking these phases of change into account in nutrition advice.

The slope stability analysis by the limit equilibrium method has the disadvantage that it can be applied only when the analysis is performed by setting the critical plane after analyzing the active surface many times and the soil is uniform and only the safety factor can be calculated. However, the analysis using the strength reduction analysis method has advantages that the engineer can judge various aspects and calculate the safety factor. In this study, the safety factor according to the change of slope and shear strength was compared and analyzed using limit equilibrium analysis and strength reduction method. It is suggested that it is desirable to use the strength reduction method which can synthetically review the stress, displacement, and strain in the soil.

The blocking of malicious traffic in groupware network system is used to prevent the spread and distribution of malicious traffic. The method protecting from malicious traffic in groupware system is designed to handle the malicious traffic of various routes with the internal course of groupware, which leads to lighten the load of security and traffic. It was impossible to block this kind of traffic at the traditional structure. When the protection of the proposed groupware system is performed, there appears to be a great change for the rate of a load factor at the CPU of Backbone Switch which is connected to the internal gateway. The load factor of CPU, which was increased with the traffic, is now remarkably reduced after the internal gateway is set up. This is to show that a lot of malicious traffic pass through the internal network and that network environment is faced to the menace of many malicious traffics. This paper is to show the efficiency of protection of internal gateway proposed in this study, for the rate of CPU of Backbone Switch was about 17% a day, but was dropped up to the 4% after the malicious traffic was removed.

Objectives: The purpose of this study was to confirm the effects of an auricular acupressure (AA) program for smoking cessation in high school students from 2015 to 2017. Methods: The study investigated 12 high school students who had been smokers. Subjects were treated for three years. Each program was composed of five AA treatments. Average daily smoking and adverse reactions were checked for one week before each procedure. The AA was administered weekly at the endocrine point, lung point, throat point, nasal fossae point, bronchial tube point, and mouth point. Results: The mean number of cigarettes smoked per day after each year of treatment significantly decreased from 5.33±3.58 to 3.54±2.08 in 2015 (p=0.046). However, it increased from 5.75±2.30 to 6.00±3.61 in 2017 (p=0.80). The number of cigarettes smoked before treatment was found to be higher than the number of cigarettes after treatment in the previous year. No significant results were obtained from analysis of the change in the amount of smoking within each year. Conclusion: Social influence, such as the subject's academic stress and peer relationships, may have been a major factor in the change in the amount of smoking. Although the AA did not show a strong effect in smoking cessation, it appears to have value as a supplementary means of stopping smoking.

PURPOSES : The use of roller-compacted concrete pavement (RCCP) is an environmentally friendly method of construction that utilizes the aggregate interlock effect by means of a hydration reaction and roller compacting, demonstrating a superb structural performance with a relatively small unit water content and unit cement content. However, even if an excellent structural performance was secured through a previous study, the verification research on the environmental load and long-term durability was conducted under unsatisfactory conditions. In order to secure longterm durability, the construction of an appropriate internal air-void structure is required. In this study, a method of improving the long-term durability of RCCP will be suggested by analyzing the internal air-void structure and relevant durability of roller-compacted concrete. METHODS : The method of improving the long-term durability involves measurements of the air content, air voids, and air-spacing factor in RCCP that experiences a change in terms of the kind of air-entraining agent and chemical admixture proportions. This test should be conducted on the basis of test criteria such as ASTM C 457, 672, and KS F 2456. RESULTS : Freezing, thawing, and scaling resistance tests of roller compacted concrete without a chemical admixture showed that it was weak. However, as a result of conducting air entraining (AE) with an AE agent, a large amount of air was distributed with a range of 2~3%, and an air void spacing factor ranging from 200 to $300{\mu}m$ (close to $250{\mu}m$) coming from PCA was secured. Accordingly, the freezing and thawing resistance was improved, with a relative dynamic elastic modulus of more than 80%, and the scaling resistance was improved under the appropriate AE agent content rate. CONCLUSIONS : The long-term durability of RCCP has a direct relationship with the air-void spacing factor, and it can be secured only by ensuring the air void spacing factor through air entraining with the inclusion of an AE agent.

Objective: To examine the effects of Trichosanthes kirilowii Maximowicz extract (TE) and Trichosanthes kirilowii Maxi mowicz Cheonghyeol Plus Phellinus linteus Cheonghyeol plus (TCP) on anti-inflammatory factor expression in human umbilical vein endothelial cells (HUVECs). Methods: HUVECs were activated with TNF-α and then treated with TE and TCP. The expression levels were then measured for intracellular genes (KLF2, eNOS, MCP-1, ICAM-1, and VCAM-1), proteins (KLF2, eNOS, MCP-1, ICAM-1, VCAM-1, ERK, and JNK, p38), and extracellular biomarkers (ICAM-1, VCAM-1, and MCP-1). Results: 1. TCP at concentrations of 100 ㎍/mL or greater significantly increased the expression of KLF2 and eNOS intracellular genes and significantly decreased the expression of ICAM-1, VCAM-1, and MCP-1 genes compared to the control group. 2. TCP at concentrations of 100 ㎍/mL or greater significantly increased the expression of KLF2, eNOS proteins compared to the control group, and significantly reduced the expression of VCAM-1, ICAM-1, MCP-1, ERK, and p38 proteins. However, JNK protein phosphorylation showed no significant change compared to the control group. 3. TCP at concentrations of 100 ㎍/mL or more significantly decreased the production of MCP-1, ICAM-1, and VCAM-1 extracellular biomarkers compared to the control group. 4. TE at a concentration of 100 ㎍/mL did not cause any significant change in the expression of intracellular genes or proteins, in the production of the extracellular biomarker MCP-1, or in the amount of JNK protein compared to the control group. Other intracellular genes, proteins, and extracellular biomarker expression showed the same trend as observed with TCP exposure. Conclusion: This study experimentally confirmed that TE and TCP could be effective in preventing or inhibiting various inflammatory vascular diseases due to their anti-inflammatory effects.

The purpose of this study was to examine the personality change of rooks that would possibly result from kitchen environment. It's basically meant to determine the relationship of environment to personality, by investigating how cooks felt about their own personality before and after working as a cook and conducting a self-diagnostic personality test based on theories on kitchen environment and personality. The subjects in this study were the cooks who served af top-rated hotels in Seoul, and the survey was carried out from April 8 through 12, 2002. The collected data were encoded and analyzed with SPSS 10.0 program. To identify the characteristics of the subjects, frequency analysis was implemented, and reliability analysis, T-test and ANOVA were employee. To verify the reliability of the questionnaire items, Cronbach's Alpha that represented internal consistency was calculated, and factor analysis was fulfilled to minimize related variables about cuisine environment and eliminate irrelevant ones. The findings of this study were as below: Out of total 27 cuisine environment variables, 22 ones boiled down to six factors. Factor 1 was conflicts, and factor 2 was job performance. Factor 3 was work, and factor 4 was environment. Factor 5 was facilities, and factor 6 was social. To make better cuisine environment each and every part of kitchen environment that affects cook personality should be improved, and further, what causes employee turnover should be eliminated. In the future, there is a need for broader research effort that could cover more extensive region and a wider variety of subjects other than cooks at the top-rated hotels.
