The purpose of this study was to investigate the characteristics and the current condition of musculoskeletal pain sufferers among fitness center users. The investigation used self-reporting questionnaire with the 797 subjects. On average, the subjects were 30.6 years old, 168.8 cm in height and 65.2 kg in weight. Among them, 423 were male (53.1%) and 374 were female (46.9%). Out of them, 276 suffered from pain, (35.2%). More men felt muscle aches than women (p<.05). In terms of pain, lower back area topped the list with 44.9%, followed by the lower extremities (30.1%), the neck (17.8%) and the upper part of the body (17.8%). Dieters suffered the most from pain (86.2%) while those exercising to build strength suffered the least with 26.8%. There was a significant relationship between the purpose for exercising and the amount of pain suffered (p<.05). By kind of exercise, pain stroke aerobic exercisers disproportionately with 42.4% while it almost steered clear of exercisers for strengthening with 26.9%. There was significant relationship between the kind of exercise and pain suffered (p<.05). The type of suffering differed by body shape. A significantly higher number of overweight people experienced pain than underweight people (p<.05). 32.8% of pain sufferers commented that the pain affects their workout, and on this issue there was no gender difference (p>.05). The pain caused more difficulties in doing activities of daily living for overweight or obese peoples than underweight peoples (p<.05). More than a third of health club and fitness center users are experiencing musculoskeletal pains. Measures such as professional training or information provision is required to prevent injury or disorder caused by improper exercise.

Objective: Although the efficacy of Rubus coreanus (RC) byproducts as a feed additive has been recognized, its effects on intestinal microorganisms and the immune system are still unknown. Methods: Six-week-old male rats were treated with 0.5% RC (T1), 1.0% RC (T2), and 1.5% RC (T3) for 4 weeks. Results: We found that treatment with RC byproducts significantly increased the daily gain of body weight and feed intake. Treg-cell differentiation was enhanced in the mesenteric lymph nodes and spleen from the rats fed with RC byproducts. Illumina sequencing showed that bacteria in the phylum Firmicutes decreased and while those in the phylum Bacteroidetes increased in RC-treated groups. Particularly, the pathogenic microorganisms in the family Peptococcaceae decreased, and the non-pathogenic families Lachnospiraceae and S24-7 increased. Quantitative polymerase chain reaction analysis showed that the RC byproducts increased the lactic acid bacteria Bifidobacterium spp., Oscillospira spp., Leuconostoc citreum, and Weissella cibaria in a concentration-dependent manner. Conclusion: RC byproducts may be effective in immunomodulation by affecting intestinal microorganisms.

The place of South Weol Dynastys authorities exhumed in the region of KangChoWu, China lies adjacent to a stone ditch through which water streams crookedly, and a dark trough of stone pond in the north side. There is a sharply curved stone ditch and a crescent-shaped water entrance made by stones. The place was separated by using stone columns and stone walls. There is a beam of ditch, a crooked entrance, a flat bridge of slate, a stepping-stone, a sluice gate, and a crooked corridor. There are big and small artificial islands, and reinforcing stone drainage way in the palace pond recently exhumed at the building site for the pavilion of Hwang-Yong Temple in Kuhwang-Dong, Gyeongju city, Korea. There are four facilities assumed to be entrance and exits at four corners and an open space on which gravel was spread extensively. A narrow road and a middle road with indefinite curves at the south of Asukakyoseki exhumed by the first, second and third and two stone buckets which one is to fill with water and the other is to drain water off like fountain are there, and besides wave protecting dam and north pond and the part that water pass were excavated. Palace ponds that were extensively distributed at old residential cities are a general phenomenon of countries in eastern Asia. Anap pond of Silla and Gungnam pond of Baekje were in Kroea. We believe that Asutnkyoseki is on the extension. Although more investigations in the background of thought and the genealogical relation about the palace pond are required, it seems that an idea was surely received from China.

Objectives : It was to translate three neck and spinal pain disability questionnaires - the Neck Disability Index (NDI), the Neck Pain and Disability Scale (NPDS), and the Functional Rating Index (FRI) - into Korean language, and evaluate the psychometric properties of Korean versions of questionnaires to achieve a good cross-cultural adaptation. Methods : Forty (23 males, 17 females) subjects aged from 15 to 64 years old, participated to examine test-retest reliability. One hundred and eighty (76 males, 104 females) subjects with a primary diagnosis of non-specific neck pain and 81 healthy volunteers were undertaken to examine internal consistemcy, discriminative validity and longitudinal construct validity. Versions of each questionnaire in idiomatic modern Korean were developed using a procedure proposed by Beaton et al. (2000). To assess reliability, the Intraclass Correlation Coefficient (ICC $_{(2,1)}$) was calculated. Internal consistency was evaluated by Cronbach's alpha. Discriminative validity was examined with independent-group t-tests. Responsiveness was tested by calculating the effect size and standardized response mean for each questionnaire and using Pearson' s r and the area under the receiver operating characteristic curve analysis. Results : Test-retest reliability ofthe translated versions of the three disability questionnaires was excellent (ICC $_{(2,1)$ = 0.86-0.90). High internal consistency was found in the three disability questionnaires (Cronbach's alpha ranged from ${\alpha}=0.88$ for the FRI to ${\alpha}=0.96$ for the NPDS and 0.82 for the Short Form McGill Pain Questionnaire(SFMPQ)). the VAS subscale of the SFMPQ was found to be the most responsive of the subscales (ES=1.44, SRM=1.37). The VAS was also the most responsive pain and disability index in internal responsiveness analysis, although disability indices showed marginally better responsiveness when compared with external standards. No floor or ceiling effects were observed. Conclusions : It is concluded that the questionnaires were successfully translated and exhibit acceptable measurement properties, and may suggest that they are suitable for use in clinical and research application.

This study was performed to investigate the effects of liquid culture of Agaricus blazei Murill on the weight gains, food efficiency ratios, serum protein and mineral levels, and serum enzyme activities in growing male rats. Sprague-Dawley rats (7 weeks old) were given four different types of diets for a succeeding period of 6 weeks, respectively: a normal diet group, a control diet group (normal diet + 15％ lard + 0.5％ cholesterol), a 30％ or 40％ A. blazei diet groups (control diet + 30％ or 40％ A. blazei in water) according to the levels of A. blazei supplementation. The body weight gains, food efficiency ratios, and the liver of the rats fed control diet, 30％ or 40％ A. blazei diets were significantly increased compared to rats fed the normal diet, but those of rats fed the 30％ and 40％ A. blazei diets were similar to those of rats fed the control diet. The concentrations of total protein, albumin, glucose, and hematocrit value in serum of rats fed the control diet, 30％ or 40％ A. blazei diets were similar to those of rats fed the normal diet. The concentrations of urea and creatinine in serum of rats fed the 30％ or 40％ A. blazei diets were similar to those of rats fed the control diet. but the urea of rats fed the 30％ and 40％ A. blazei diets were significantly decreased compared to rats fed the normal diet. The concentrations of Ca, P, Fe and Mg, and $Ca^{++}$, $K^+$, $Na^+$ and $Cl^-$ of rats fed the control diet, 30％ or 40％ A. blazei diets were similar to those of rats fed the normal diet. There were no differences in the activities of aspartate aminotransferase, alanine aminotransferase, $\gamma$-glutamyltranspeptidase and alkaline phosphatase in the serum among the experimental groups. In conclusion, the rats fed the A. blazei maintained normal protein and mineral levels, and enzyme activities of serum. But the A. blazei feeding could not decrease the body and liver weights in the rats fed high cholesterol diets.

The Bunhuangsa stone pagoda, constructed in AD. 634, National Treasure no. 30, has been named as 'brick-copied pagoda' since the Japanese-ruling period by scholars. It is said that the Chinese brick pagoda was its precedent model, however the Bunhuangsa Pagoda is the oldest of all the Chinese-style brick pagodas except one, the Sungaksa Pagoda. The Chinese pagoda cannot have been a precedent model to copy due to its complex detail of wood vestige, as the Bunhuangsa pagoda is simple form without ornament. Domestic brick pagodas cannot have been a precedent model to copy as well, because all the domestic brick pagodas are younger than the Bunhuangsa Pagoda. Therefore, the terminology 'brick-copied pagoda' is a fallacy; it is rather that later brick pagoda copied the precedent the Bunhuangsa stone pagoda. The Bunhuangsa Pagoda is simply a piled-up pagoda of thick or thin, big or small slates of stone, facing only one smooth side and therefore needing nothing to relate to brick. The originality of the pagoda is more related to simple piled-up Indian stone stupa rather than Chinese brick pagoda. The roof form of its gradually stepped projection comes from the harmika of the summit of Indian stupa. Contrary to general history, old Silla Dynasty imported Buddhism directly from India by sea. From written national history and by temple foundation history, the Indian Buddhism evangelist possibly made influence to the erecting of temple and pagoda. The original wrong terminology has made a harmful effect gradually to the naming of mass-styled stone pagoda of only carved stepped-roof form after brick-copied pagoda. The false term 'brick-copied pagoda' should be discarded, which comes with superficial observation based on toadyism to China and colonialism to Japan. Instead of the fallacious term, this paper suggests multi-storied 'piled-up pagoda with slate stone.'

Essence of the Hwangchil tree (黃漆樹 Dendropanax morbiferus H.Lév.) has been used for various purposes, like waxing emperor's armors, covering an astrology board, or, during the Silla Dynasty, burying it to block something bad in the soil symbolically. Essence of the Hwangchil tree was known to have remarkable preservation effects such as waterproofing, damp-proofing, rust-proofing, and moth-proofing as well as not being easily peeled off from even soft surfaces like paper. There is a record in Prescriptions for Epidemic diseases of Cows, Horses, Sheep, and Pigs (牛馬羊猪染疫病治療方), published in 1541, of Hwangchil that is local to Jeju Island being used instead of benzoin (安息香), of burning Hwangchil, and of making cows inhale its smoke to prevent plague among them. Along the same lines, there are records in the Local Chronicle of Tamra (耽羅志) and the Book of Earth Geography (輿地圖書) that identify Hwangchil with benzoin. In Seonghosaseol (星湖僿說), a book written by Lee Yik in around 1760, it is acknowledged that Hwangchil could be medicinal herb. In 2000, Ahn Duk-Kyun registered the roots and branches of Hwangchil tree as 'Boncho' (本草 herbal medicine) in the Pictorial Book of Korean Medicinals (韓國本草圖鑑) and presented the method of taking it for medical purpose. Researchers have suggested that Hwangchil essence as well as diverse parts of the plant such as its roots, branches, leaves, flowers, fruits, and gum have various meaningful medicinal properties. Regarding the history and recent researches of using Hwangchil tree, it has various medicinal probabilities such as, 'dispersing miasma' (辟邪), 'opening holes' (開竅), 'waking the heart' (醒心), 'smoothing spirits' (安神), 'piercing the block' (疎泄), 'removing the old and welcoming the new' (去故生新). This paper contributes ideas about how to expand the uses of Hwangchil Tree.

Purpose: The purpose of this study was to conduct an analysis of kinematics of lower extremities and trunk in stance phase of walking according to turning direction. Methods: Ten university students (five male, five female) who were in their 20s (mean age was 20.6 years old) participated in this study. Participants did not have participants did not have any problem with skeletal muscular system. We used the "Qualisys motion capture system" for analysis of trunk and lower extremity movement in stance phase of walking according to turning direction. We collected data while subjects walked a distance of 10 m, and at the 6 m line, subjects were required to turn to the left side and the right leg was positioned in stance phase and the left leg was positioned in swing. For data analysis, the SPSS for Windows ver. 20.0 statistics program was used in performance of one way analysis of variance according to turning direction. Results: Significant difference of trunk and lower extremities was observed for turning direction according to walking cycle (p<0.05). Upper trunk movement showed a greater increase at three dimensions than lower trunk, and in heel off phase, pelvic movement showed a greater increase than lower trunk (p<0.05). In 45 degree and 90 degrees of turning direction, all movements of trunk and lower extremities were significantly different among three events of stance phase (p<0.05). Conclusion: We suggest that three-dimensional movement analysis of trunk and lower extremities during turning movement was very important in order to indicate increasing balance or walking ability for people with impaired movement or walking.

We investigated the effects of newly synthesized 4-[(butylsulfinyl)methyl]-1,2-benzenediol (SMBD) on the prevention of atherosclerosis in hypercholesterolemic rabbits. SMBD exhibited stronger inhibition of $Cu^{2+}$-induced low-density lipoprotein oxidation than that of ascorbic acid or simvastatin. Three-month-old rabbits were fed an atherogenic diet containing 0.5% cholesterol and 10% coconut oil, while other two groups were given an atherogenic diet with intravenous injection of either simvastatin or SMBD (0.33 mg/kg/day) for 4 weeks. The concentrations of plasma cholesterol and thiobarbituric acid reactive substances were significantly decreased in SMBD groups, compared to the control group. Also, aortic lipid level in the SMBD group significantly lower than that in the control group. Furthermore, compared with the control group, the SMBD group significantly inhibited the increase of aortic intimal thickness by 36% via reducing of aortic reactive oxygen species and cyclooxygenase-2 protein levels. We conclude that raised antioxidant effect of SMBD results in significant prevention against hypercholesterolemia.
