The effects of Semen Ziziphi Spinosae extract were tested for the anti-stress action. 100g of crude drug of Semen Ziziphi Spinosae was extracted with pure water and the total extractive was evaporated under reduced pressure to give 10.7g. ICR male mice($20{\pm}2g$) were fed orally with the dose of 100mg/kg/day for five days. Foot shock was given to make experimental environment of physiological stress. Foot shock mice were placed individually in the foot shock compartments and sociopsychological mice were placed nonfoot shock compartment-the side of foot shock compartments. Mice were exposed to sociopsychological stress by restraining and seeing foot shock stressed mice for one hour for five days. Semen Ziziphi Spinosae extract administered group showed a significant decrease of serum corticosterone secretion compared with control group. Noradrenaline secretions in the dorsal cortex of brain were increased but not significant. Lipid peroxidation of the liver of mice were tested by measuring malondialdehyde, and Semen Ziziphi Spinosae extract had tendency of decreasing lipid peroxidation but not significant. But Semen Ziziphi Spinosae extract administration had the effect of decreasing serum level of aspartate aminotransferase and malondialdehyde. These results suggest that Semen Ziziphi Spinosae extract can effectively rid the sociopsychological stress and stress concerned diseases.

Purpose : The purpose of this study was to find the effect of foot bath on blood pressure(BP) following treadmill exercise. Methode : Subject of study were forty healthy males without any cardiovascular, musculoskeletal, and neurologic diseases. Following twenty minutes walking at a speed of 5m/s on the treadmill, ten twenty subjects in experimental group received foot bath, on the dominant lower limb while sitting in chair. Foot bath was applied to the level of the lateral and medial malleoli keeping the temperature of the paraffin bath at $40{\pm}0.5^{\circ}C$. Twenty subjects in control group took a rest sitting in chair in a comfortable position. BP was measured in right brachial artery. BP was measured five times(before exercise, immediately after exercise, 5 minutes, 10 minutes, and fifteen minutes after exercise). Results : The study showed that for diastolic blood pressure, there was no significant difference between the experimental and the control group. However, systolic blood pressure(SBP) increased significantly after exercise compared with SBP before exercise (p<.05). In addition, SBP in five minutes after exercise decreased significantly compared with SBP in immediately after exercise (p<.05). On the other hand, the control group had significant difference between SBP measured before exercise and SBP measured at the other measure time (p<.05). In five minutes after exercise, SBP in experimental group had significant difference with SBP in control group (p<.05). Similarly, in ten and fifteen minutes after exercise, SBP in experimental group had significantly difference with SBP in control group (p<.05). Conclusion : Consequently it was confirmed that when foot bath was applied, the increased BP induced by the exercise returned to normal range rapidly.

This study investigates the impact of livestock diseases, including FMD(foot-and-mouth disease) and MCD(mad-cow disease), on pork demand in Korea. TV news stories about the livestock diseases were considered as negative advertising, and therefore the carry-over effect of negative advertising was combined with the pork demand model in conjunction with an exponential distributed lag function. The asymmetry hypothesis was imposed, however it was accepted that demand response does not show different sensitivities to increases and decreases in the livestock disease news. FMD news had a negative effect on pork demand, whereas MCD news had a positive effect, yet FMD news had a greater effect on pork demand than MCD news. The pork demand elasticity estimates for FMD and MCD news were -0.0071 and 0.0028, respectively. The cross-elasticity of the imported beef price to pork demand was highly inelastic, but it was elastic during the beef import embargo.

In countries with FMD vaccination, as in Korea, typical clinical signs do not appear, and even in FMD positive cases, it is difficult to isolate the FMDV or obtain whole genome sequence. To overcome this problem, more rapid and simple NGS system is required to control FMD in Korea. FMDV (O/Boeun/ SKR/2017) RNA was extracted and sequenced using Ion Torrent's bench-top sequencer with amplicon panel with optimized bioinformatics pipelines. The whole genome sequencing of raw data generated data of 1,839,864 (mean read length 283 bp) reads comprising a total of 521,641,058 (≥Q20 475,327,721). Compared with FMDV (GenBank accession No. MG983730), the FMDV sequences in this study showed 99.83% nucleotide identity. Further study is needed to identify these differences. In this study, fast and robust methods for benchtop next generation sequencing (NGS) system was developed for analysis of Foot-and-mouth disease virus (FMDV) whole genome sequences.

Objectives : This study is designed to investigate the association between Samcho-gyeong(TE) and the lower branch of Meridian system. Methods : The base of the study was established by searching for the historic conception of Samcho. Thereafter the meaning of lower correlation was considered and the property of lower part of Samcho Meridian system studied. Results : Samcho is a kind of Yug-Bu(Six hollow viscera, 六腑). It is a functional internal organ, which has been continuously controversial in history. It covers wide range of the internal organs and plays various kinds of roles. Samcho and Simpo lack in interrelation of obverse and reverse. The conception of Sanghap(Upper correlation, 上合) in Naegyeong supplements the deficiency. To establish the conception of Sanghap between Yug-Bu and Hand meridians, there should be established the conception of Hahap(Lower correlation, 下合) between Yug-Bu and foot meridians for treating lower parts. The existence of Hahaphyeol(Lower confluent points, 下合穴) reveals that there were a lot of limits in treating JungHa-cho(Middle and Lower energizers, 中下焦) diseases only with the acupoints of the Hand meridians. Jogsamcho(Triple energizer of foot, 足三焦) meridian written in Taeso(太素), corresponds to the lower leg, and it is believed that it engages in treating diseases in the trunk of the body and Hacho(Lower energizer, 下焦). Conclusions : Therefore, it is believed that the lower part of meridian of Samcho can deal with the symptoms of lower back pain, leg pain, bladder disease, and so on. This study is meaningful in that it expands the range of treatment in acupoints of the regular meridians.

Fungi cause a number of plant and animal diseases. Because fungi are more chemically and genetically similar to animals than other organisms, this makes fungal diseases very difficult to treat. Human fungal infections are uncommon in normally healthy persons, being confined to conditions such as candidiasis (thrush) and dermatophyte skin infections such as athlete's foot. However, in the immunocompromised host, a variety of normally mild or nonpathogenic fungi can cause potentially fatal infections. Furthermore, the relative ease with which people can now visit 'exotic' countries provides the means for unusual fungal infections to be imported into this country. Fungal infections or mycoses are classified depending on the degree of tissue involvement and mode of entry into the host. These are Cutaneous, Subcutaneous, Systemic, and Opportunistic. As listed above, in superficial mycoses infection is localised to the skin, the hair, and the nails. An example is 'ringworm' or 'tinea', an infection of the skin by a dermatophyte. Ringworm refers to the characteristic central clearing that often occurs in dermatophyte infections of the skin. Dermatophyte members of the genera Trycophyton, Microsporum and Epidermophyton are responsible for the disease. Tinea can infect various sites of the body, including the scalp (tinea capitis), the beard (tinea barbae) the foot (tinea pedis: 'athlete's foot') and the groin (tinea cruris). All occur in the United Kingdom although tinea infections, other than pedis, are now rare. Candids albicans is a yeast causing candidiasis or 'thrush' in humans. As a superficial mycoses, candidiasis typically infects the mouth or vagina. C. albicans is part of the normal flora of the vagina and gastrointestinal tract and is termed a 'commensal' However, during times of ill health or impaired immunity the balance can alter and the organism multiplies to cause disease. Antibiotic treatment can also alter the normal bacterial flora allowing C. albicans to flourish. If we study mycoses of the orient medicine, we can improve the medical skills about mycoses.

This study attempted to evaluate the direct and indirect effect of emotional labor, job and psychosocial stress, and fatigue of beauty industry workers on their musculoskeletal diseases. The findings of this study showed that, among the workers with perceived symptoms of musculoskeletal diseases, the body part with the most commonly occurring symptom was the shoulder, followed by neck, low back, wrist, arm, foot and knee. As for the effect of work-related psychological factors on musculoskeletal diseases, it was found that the workers with musculoskeletal diseases were more affected by emotional labor and fatigue than non-symptom workers. It was also shown that when their job stress increased, the fatigue level also increased, though their psychosocial stress decreased. In addition, it was found that both direct and indirect effects of emotional labor on fatigue were high, and the indirect effect of job stress through fatigue on musculoskeletal diseases was significant.

The emergence of highly contagious viral diseases of livestock and poultry such as foot-and-mouth disease (FMD), African swine fever (ASF) and highly pathogenic influenza (HPAI) have necessitated the formulation of policies and regulatory frameworks for preventing ingress of exotic diseases and controlling dissemination of endemic diseases within the country. The disease control ratings to manage contagious livestock disease in farms have not being widely used because the evaluation parameters were not being considered inappropriate. The purpose of this study was to reinforce the validity of the parameters for evaluation factors and the objectivity of the scoring criteria in the application of the current disease management rating system. The diseases subject to intensive management were improved by reflecting farm situation. For the evaluation based on the disease grading system of farms, the diseases subject to intensive management were realized, the list of diseases for evaluating the vaccination rate was revised, and the quarantine and sanitation management standards were revised. The effectiveness of the improved livestock disease management system was confirmed through the application of actual pig farms. Therefore, this system will be used as a means to evaluation the biosecurity at the farm units. Through this, it will contribute to establish effective biosecurity measures for each farm by improving and supplementing the present disease grading system.

Walking shoes for walking and jogging have been used to enjoy lots of leisure time. Functional shoes such as walking shoes have special functions to improve body motility by changing of shoe shapes. The walking shoes could improve the motility by structural transformation of outsole as increase degrees of heel and toe. The study on insoles has not been conducted enough on the contrary of the study of outsole. The purpose of this study is to perform ergonomics analysis whether the Arch Supported insoles have an improving effect of muscle activities or not. Experiments were performed with 6 subjects who are health and haven't experienced any diseases past. EMG(Electromyography) and Foot Pressures were measured repeatedly for 5 seconds at 0 hour, after 1 hour and after 2 hours of walking. Insoles used for experiment are normal insole, insole inserted Arch Support and pad. The electrodes for EMG measurement were set on waist (erector spinae), and thigh (vastus lateralis), calf (gastrocnemius). Evaluations of EMG were analyzed by shift of MF (Median Frequency) and MPF (Mean Power Frequency). Foot Pressure was analyzed by mean pressure of feet and change of walking time. As results, Arch Support insole had larger frequency shift value than that of normal insole. Frequency shift between Arch Support insoles and normal insole showed significant difference on 95% confidence interval. And insole 1 has the highest value of frequency shift. For results of foot pressure, Arch Support insoles show continuous decreasing tendency when comparing with normal insoles by changing of times. Also, insole 1 has the highest decreasing value of foot pressure. Therefore, this study presented that the Arch Support insole can promote muscle activities and improves comfort for a prolonged walking.
