Coal tar is the primary feedstock of premium graphitizable carbon precursor. Coal tars are residues formed as byproducts of thermal treatments of coal. Coal tar pitches were prepared through two different heat treatment schedules and their properties were characterized. One was prepared with argon and oxidation treatment with oxygen; the other was prepared with oxygen treatment at low temperature and then argon treatment at high temperature; both used coal tar to prepare coal tar pitches. To modulate the properties, different heat treatment temperatures ($300{\sim}400^{\circ}C$) were used for the coal tar pitches. The prepared coal tar pitches were investigated to determine several properties, such as softening point, C/H ratio, coke yield, and aromaticity index. The coal tar pitches were subject to considerable changes in chemical composition that arose due to polymerization after heat treatment. Coal tar pitch showed considerable increases in softening point, C/H ratio, coke yields, and aromaticity index compared to those characteristics for coal tar. The contents of gamma resin, which consists of low molecular weight compounds in the pitches and is insoluble in toluene, showed that the degree of polymerization in the pitches was proportional to C/H ratio. Using an oxidizing atmosphere like air to prepare the pitches from coal tar was an effective way to increase the aromaticity index at relatively low temperature.

Purpose: Electrical stimulation is one of several treatments recommended for RA patients. Electrical stimulation of RA patients, reduces pain, or facilitates joint motion prior to exercises. However, there is still limited evidence on the efficacy of electrical stimulation and thus any conclusions drawn about this method remain controversial. Recently, Microcurrent Electrical Neuromuscular Stimulation (MENS) has received significant attention as a potential method of electrical stimulation. In this study, we investigated the effect of microcurrent treatment in rheumatoid arthritis rat. Methods: Subjects were allocated either to the control group or experimental group, which was subject to microcurrent stimulation. Interleukin-1 expression in the metatarsophlangeal joint and the oedema index in the ankle were used for classification and subsequent evaluation of pathology. Subjects were assessed at 1, 7 and 14 days after inducing rheumatoid arthritis through adjuvant injection. Thirty-six subjects, 18 in each group, were used in this study. Statistical analysis was performed by calculating the differences between the two groups and between each interval assessment. Categorical variables were compared between the two groups with the paired-T test. The one-way ANOVA test was performed to assess changes in ordinal variables. Results: Baseline characteristics were similar in both groups. Statistically significant differences were found between the two groups. The biological marker of pro-inflammatory cytokine and oedema index were decreased in response to this treatment. Conclusion: These data show that treatment of rheumatoid arthritis with a microcurrent stimulation device reduced the oedema index and pro-inflammatory cytokine IL-1.

This study was performed to investigate the relationship between Forward Head Posture(FHP) and Craniomandlbular Disorders(CMDs). Many studies reported that there was some relationship between them, however, there is still controversy. So It Is necessary to observe and compare many more patients with CMDs wirh normal controls. For the study 85 patients with CMDs and 37 dental students were selected as experimentals and controls, respectively. And the experimentals were classified Into two groups, that is, TMJ internal derangement group and muscle disorders group according to clinical diagnosis. For measuring the FHP, CROM(Cervical-Range-of-Notion)was used. This goniometer is composed of three part. First, gravity goniometer for flexion and extension. Second, magnetic compass and yoke for rotational movement. And last, forward head arm and vertebra locator for forward head posture. Next T-Scan, electronic occlusal analyzer, was used for recording of occlusal contact state. Other items such as maximum opening, lateral excursion, Helkimo's anamnestic index, and muscle palpation point from Friction's craniomandibular index were checked clinically by one examiner. The result of this study were as follows : 1. In male, control group showed much more measurement in resting forward head posture than did experimental group. But there were not significant differences between groups in female subject. From this results, the author contended that CROM is new measuring system and differ from other goniometers in some aspect, so that results should be re-evaluated 2. Mean value of maximum mouth opening in nearly all groups were greater than 40mm. and mouth opening had a significant correlation with occlusal force and with anamnestic index both sex. 3. Mean value of palpation point had not any correlationship with forward head posture in both sex, but there was significant difference between upper and lower group by rounded shouldes. 4. In summary, there was no significant relationship between forward head posture and sign and symptom of Craniomandibular Disorders.

The purpose of this study was to analyze the gait characteristics and interaction between lower extremity joints according to shoe's heel heights in young women. Participants were selected as subject consisted of young and healthy women (age: $23.71{\pm}1.49yrs$, height: $165.92{\pm}2.00cm$, body weight: $54.37{\pm}3.46kg$) and walked with 3 types of shoe's high-heel (0, 5, 9 cm). The variables analyzed consisted of the displacement of Y axis in center of mass ([COM]; (position, velocity), front rear(FR) and left right(LR) angle of trunk, lower extremity joint angle (hip, knee, ankle) and asymmetric index (AI%). The displacement of Y axis in COM position showed the greater movement according to increase of shoe's heel heights, but velocity of COM showed the decrease according to increase of shoe's heel heights during gait. The hip and knee angle didn't show significant difference statistically according to increase of shoe's heel height, but left hip and knee showed more extended posture than those of right hip and knee angle. Also ankle angle didn't show significant difference statistically, but 9 cm heel showed more plantarflexion than those of 5 cm and 0 cm. The asymmetric index (AI%) showed more asymmetric 9 cm heel than those of 0 cm and 5 cm. The FR and LR angle in trunk tilting didn't show significant difference statistically according to the increase of shoe's heel height during gait in young women.

Purpose : This study examined how of nursing students affects their academic self-efficacy and communication ability on self-leadership. Methods : The subjects of this study included 269 nursing students enrolled in a college located in City B, South Korea during a period between June and July 2021. The collected data were analyzed using SPSS/WIN 22.0 program to compute frequency, percentage, mean and standard deviation and conduct t-test, ANOVA, Scheffe's test, Pearson Correlation Coefficient, and multiple regression analysis. Results : The nursing students had average academic self-efficacy of 3.10±.42, communication ability of 3.78±.53, and self-leadership of 3.16±.44. Among the self-leadership sub-factors, self-reward was the highest with 3.94±.74 points. The academic self-efficacy of the subjects demonstrated a significant difference according to happiness index (F=8.83, p<.001) and health (F=3.38, p=.035). The communication ability showed a significant difference depending on year of study (F=5.62, p<.001), happiness index (F=5.95, p<.001), and experience of clinical training (t=-3.57, p<.001). The self-leadership demonstrated a significant difference according to year of study (F=4.28, p=.006), satisfaction with major (F=7.37, p<.001), happiness index (F=3.68, p=.013), and experience of clinical training (t=-3.41, p<.001). A positive correlation was observed between the subject's academic self-efficacy and communication ability (r=.40, p<.001), as well as the academic self-efficacy and self-leadership (r=.45, p<.001). The communication ability (𝛽=.36, p<.001) was proven to be the strongest influential factor on the self-leadership, followed by academic self-efficacy (𝛽=.28, p<.001), satisfaction with major (𝛽=.13, p=.011), and experience of clinical training (𝛽=.13, p=.013). Conclusion : This study results imply that repeated studies that investigate the nursing students' academic self-efficacy, communication ability, and self-leadership are required.

Purpose: The study examined obesity conditions and related factors in middle aged Korean women who had been diagnosed as obese based body mass index (BMI) or waist circumference (WC) measurement. Presently, BMI alone, WC alone, or BMI + WC were used as obesity measures. Methods: Subjects were 488 women 40~64 years of age living in one city, Korea. Structured questionnaires concerning general characteristics, health behavior practices, and chronic disease history were completed by each subject. Results: The proportions of obesity were 42.4% by BMI, 39.3% by WC, and 51.3% by the combination of both measurements. Chi-square test revealed significant associations of obesity with age, education level, menopausal status, frequency of excessive eating, and history of diabetes mellitus or hypertension. These associations were similar for the three measurement schemes. There was significant positive relationship between BMI and WC, whereas the relationship between BMI and WHR (waist-hip ratio) was not significant. Conclusions: The combination of BMI and WC measurement may be a valid way to evaluate the obesity status in middle-aged women. Developing an obesity management program that includes control of excessive eating, and consideration of menopausal status and history of chronic diseases would be prudent.
