In the taste of patients suffering from arthritis, while the group of patients falling that ill at first and the recurring group didn't smoke cigarets, during alcohol and coffee on the whole, and the group of patients falling once again that ill drank a cup of distilled linquor and three cup of coffee or more on the whole per one day, and the group of patients falling that ill at first liked sort of vegetables and the recurring group liked very much sons of vegetables and fresh and meat in their loving food normal times. 10. Analysing the distribution on the dining table used by patients and the structure of a powder room, at first, in the structure of a powder room, the group of patients filling that ill have a toilet stool using as their sits, and a Bush toilet on the whole, and the recurring group, a toilet stool using as their sits and conventional type, and in the structure of a dinning table, the group of patients falling that ill at first and the recurring group turned high, each as 66.9% and 6.3%, who have a dining table carring here and there. 11. In the distribution of patients of arthritis in relation to stress, the case that they feeled severly symptoms of arthritis when thay got stress, turned high, each, as 78.6% in the recurring poop, and the case not knowing, as 61.5% in the first group. In the extent of stress normal times, the case that they got much stress on the whole turned high, each, as 72.4% in e recurring group, and the care that got less stress on the whole, as 60.0%. 12. In the distribution on the distinction of symptoms and impedimental extent, the recurring group turned high in each variable. Analysing the feature of the recurring group, in the distinction of symptoms, the case that they fooled much that the node of an articulation is stiff, turned high, as 71.6, and in the distinction of treatment before. patients came to helpk, the theraphy of Chinese medicine (physical theraphy), as 84.4%, the theraphy of Chinese medicine (acupuncture, moxacautery, Chinese medicine), as 73.2%, and in the distinction of the satisfing extent on treatment, the case of comman, as 72.3%, and in the cause of arthritis, the case not recruiting their health after a birth, as 68.5%, and the case not recovering wholely an articulation having got hurt, as 62.8%, and in the state of physical exercise before they begined suffering from arthritis, the case exercising very much on the whole, (as 74.2%), and in the extent of subjective impediment, the case of not being able to act almost, as 66.7%, the case of acting but feeling some hard, as 66.3%. 13. The correlation in variables in relation to arthritis Analysing realted variables, the recurring frequency showed correlation with such as the extent that patients got stress normal times, and the exercising state before suffering arthritis, and showed contra-correlation with academic careers, the wights, coffee. The cigaret, e loving food of taste, showed corralation with the weight, stature, alcohole as the loving food of taste. On the basis of this result medical members of heal, who are related to the regular education, public education or development of this program, should be concerned to prevent orthris.

The extraction efficiency of orange-yellow pigment from the Gardenia was greatly depended upon the extraction time, extraction temperature, volume of solvent used and fat contents of the Gardenia. From the experimental results, the amounts of extracted pigment (P) was proportional to the $log\;t^{\;1{\cdot}15}$ of extraction time$(t;\;0{\sim}60\;min.)$, the $log\;T^{3{\cdot}73}$ of extraction temperature$(T;\;5{\sim}60^{\circ}C)$, the $log\;S^{3{\cdot}7}$ of volume of solvent$(S;\;5{\sim}50\;ml)$, and the -4X of fat contexts of sample $(X;\;0{\sim}0.\;15)$ at $18^{\circ}C$ for 10 minutes. Finally, the modified empirical equation was derived as follow; $P{\simeq}1.15\;log\;t+3.73\;log\;T+3.7\;log\;S-4X-6.4$ In addition to that, the most optimum conditions of pigment extraction were determined as 30 minutes of operation time, $40^{\circ}C$ of temperature. Deffated Gardenia was more productive than natural Gardenia in the pigment extraction.

This study evaluates the financial status of Korean households using Household Financial Composite Index (HFCI) proposed in the preceding study. We analyzed 1,566 households with four persons aged 30-59 using raw data from the Korea Labor Panel Survey in 2016. The analysis results are as follows. First, HFCI was found to be 57.0 out of 100. Growth Index as one of three subindices was 11.1, which was significantly lower with 65.0 points for Status Index and 61.1 points for the Stability Index. Second, for households with male household owners, the overall financial score was 57.0, while that with female owners was almost similar with 57.2. HFCI was similar for the owner's age groups, but for Status Index, 58.5 for 30s, compared with 66.1 for 40s and 67.1 for 50s. The higher the education level of household owners, the better HFCI, with 53.2 high school graduates and 64.8 graduate graduates, showing a high gap of 11.6 points. HFCI for households living in owned housing was highest at 60.0, while that for rented housing was 40.7. Third, after controlling other effects, it was found that HFCI differed according to the level of education and ownership of housing living. Householder's gender was not found as a significant factor on HFCI. Status Index The 40s and 50s was higher than those in their 30s. Fourth, households were divided into three groups based on HFCI, named as risk, average and secure groups. HFCI for the risk group was 26.8, which was lower than 78.6 for the secure group, with a Status Index of 19.3. Households in their 50s and graduate school graduates were significantly included in the list of secure groups than others.

Background: Robot-assisted gait training (RAGT) is an effective method for walking rehabilitation. Additionally, the body weight support (BWS) system reduces muscle fatigue while walking. However, no previous studies have investigated the effects of RAGT with BWS on isokinetic strength of quadriceps and hamstring muscles. Objects: The purpose of this study was to investigate the effects of torque, work, and power on the quadriceps and hamstring muscles during RAGT, using the BWS of three conditions in healthy subjects. The three different BWS conditions were BWS 50%, BWS 20%, and full weight bearing (FWB). Methods: Eleven healthy subjects (7 males and 4 females) participated in this study. The Walkbot_S was used to cause fatigue of the quadriceps and hamstring muscles and the Biodex Systems 4 Pro was used to measure the isokinetic torque, work, and power of them. After RAGT trials of each of the three conditions, the subjects performed isokinetic concentric knee flexion and extension, five at an angular velocity of 60°/s and fifteen at an angular velocity of 180°/s. One-way repeated analysis of variance was used to determine significant differences in all the variables. The least significant difference test was used for post-hoc analysis. Results: On both sides, there were significant differences in peak torque (PT) of knee extension and flexion between the three BWS conditions at an angular velocity of 60°/s and 180°/s conditions. A post-hoc comparison revealed that the PT in the BWS 50% was significantly greater than in the BWS 20% and the FWB and the PT in the BWS 20% was significantly greater than in the FWB. Conclusion: The results of this study suggest that the lower BWS during RAGT seems to lower the isokinetic torque, work, and power of the quadriceps and hamstring muscles because of the muscle fatigue increase.

Purpose: To evaluate the effect of a gymnastics program for eight weeks to maintain better body composition and decrease fatigue among factory workers. Methods: Data were collected in 54 female workers in their 50s and 60s in a factory located in the S city of the K region between April and July in 2019. The subjects were divided into two groups: 1) experimental group (n=27) received a 30 minute-gymnastics program three times per week, and 2) control group participated in lecture series about the principle and effect of the gymnastics program. Body composition and fatigue levels were measured before and after the intervention and analyzed using the SPSS 23.0 program. To evaluate the differences in demographic and clinical characteristics between the experimental and control groups, the chi-squared test and the t-test were used. Repeated measures two-way ANOVA was performed to evaluate the change between outcomes of the pre-and post-investigation. Pairwise comparisons were used to assess the differences between the groups and the time. Results: There are statistically significant differences in body fat mass (p<.001), body fat percentage (p<.001), basal metabolic rate (p<.001), and body mass index (p<.022) in the experimental group compared to the control group. In particular, there is a significant interaction between the groups and the time in body fat mass (F=6.308, p=.015), basal metabolic rate (F=11.397, p=.001), fatigue (F=6.933, p=.011). Conclusion: Our findings suggest that using the gymnastics program helps women in their 50s and 60s who work in factories promote better body composition and reduce fatigue levels.

Before examining stress and physiological variables (immunity, inflammation), this study conducted a pilot test to provide basic data by analyzing depression and anxiety symptoms by age group for stress coping and coping methods. As a non-face-to-face method, BDI and STAI by age group (20s to 70s) and face-to-face survey were conducted concurrently and as follow-up surveys. In 20s to 60s, according to the coping method, there was a significant decrease after stress relief, and in all age groups, anxiety decreased significantly after stress relief, and in the 50s, stress coping with exercise was the lowest after stress relief. Based on the results of this study, through basic research according to psychological variables, physiological variables according to actual stress coping methods were further verified, and subjects with high stress levels were treated with long-term exercise therapy for depression and anxiety symptoms by exercise therapy. It will be necessary to additionally verify the appropriate stress coping method for each age group and subject, such as the correlation between improvement and immunity and inflammatory response.

recent times, the monthly rent in the Jongno-gu Historical and Cultural Street in Seoul has rapidly increased, because of the presence of large-scale franchises and the entry of private investment into the traditional and local businesses focusing on Bukchon, Seochon, Insa-dong, and Samcheong-dong. As a result, the business environment for these merchants has worsened, due to the increasing economic burden. In order to maintain the business environment of the merchants, it is necessary to evaluate the potential for establishing a regional commercial area, in order to resolve the problems of the existing commercial areas and to improve the locational, economic, cultural and political environment. This study analyzed the factors influencing the merchants' satisfaction with the business environment as a function of their age, by considering three age groups, viz. 30-49, 50-59, and more than 60, considering the locational, economic, cultural and political environment of the merchants. Among the factors influencing the satisfaction with the business environment, the merchants in their 30s and 40s placed more emphasis on the traffic accessibility, floating population, store premium and monthly rent than the other age groups. Among the factors influencing the satisfaction with the business environment, the merchants in their 50s placed more emphasis on the cultural organization, artist activities, expansion of community support facilities, and banning of franchises in certain locations than the other age groups. Among the factors influencing the satisfaction with the business environment, the merchants over 60 years old placed more emphasis on the walking accessibility, monthly sales, merchant community, preservation of historical and cultural landscape, and commercial protection of the government than the other age groups.

There were 35 typhoons affecting Korean Peninsula from 1999 to 2009(The average annual number of typhoon is 3.18). Among these typhoons, the number of typhoon passing through the Yellow sea, the Southern sea and the East sea were 14, 6 and 15 respectively. Wind speed on the height of 10 m can be finally estimated using the surface roughness after we calculate wind speed on the height of 300 m from the data on the surface of 700 hPa. From the wind speeds on the height of 10 m, we can understand the regional distributions of strong wind speed are very different according to the typhoon tracks. Wind speed range showing the highest frequency is 10~20 m/s(45.69%), below 10 m/s(30.72%) and 20~30 m/s(17.31%) in high order. From the analysis of the wind speed on the hight of 80 m, we can know the number of occurrence of wind speed between 50 and 60 m/s that can affect wind power generation are 104(0.57%) and those of between 60 and 70 m/s that can be considered as extreme wind speed are even 8(0.04%).

Background: The use of regional local anesthetics or opioids during laparoscopic cholecystectomy (LC), in combination with general anesthesia, has been investigated in several interventional studies. Methods: We studied a total of 240 (n = 60, each) patients who were undergoing LC, and they received local infiltration and intraperitoneal instillation with normal saline or 0.25% levobupivacaine 60 ml. Group R (S) received infiltration of normal saline 20 ml before incision and at the end of surgery and then 40 ml intraperitoneal instillation after removal of the gall bladder under remifentanil-based anesthesia. Group R (L) received 0.25% levobupivacaine instead of normal saline in the same method like group R (S). Group S (S) received the same method as group R (S) under sevoflurane based anesthesia in place of remifentanil. Group S (L) received 0.25% levobupivacaine instead of normal saline with the same method as group S (S). Pain was assessed on a visual analog scale at 1, 6, 12 and 24 hours after operation. Results: The pain intensity of Group R (L) was significantly lower than that of group R (S), and the the incisional pain of group S (L) was significantly lower than that of group S (S) in the first six hours. The time delay to first operative analgesics in group R (S) and group S (S) was significantly shorter than that of group R (L) and group S (L). Conclusions: Infiltration and instillation of levobupivacaine reduced the postoperative pain and remifentanil did not increase the pain severity and opioid requirement when performing the LC.
