  • The period circadian clock gene 3 (PER3) plays a role in the mammalian circadian clocksystem. A regular exercise regime may affect the PER3 transcription in skeletal muscle. Although the effects of day length on circadian and circannual processes are well established in humans and mice, the influence of exercise on these processes in the horse has not been investigated. The present study investigated the expression of the PER3 gene following exercise in a thoroughbred breed of Korean horse. In addition, a comprehensive in silico nonsynonymous single nucleotide polymorphism (nsSNP) analysis of the horse PER3 gene and predicted effects of nsSNPs on proteins were examined. The expression of PER3 in skeletal muscle was significantly upregulated after exercise. Four nsSNPs were functionally annotated and analyzed by computational prediction. The total free energy and RMSD values of PER3 gene showed causative mutations. The results showed that nsSNP s395916798 (G72R) was associated with residues that have stabilizing effects on structure and function of PER3 gene. This study documented role of PER3 gene in phenotypic adaptation related to exercise in skeletal muscle. Further, the SNPs in PER3 could serve as useful biomarkers of early recovery after exercise in racehorses.

  • The present study was performed to analyze and review the physical and immune responses to overtraining syndrome in humans. Overreaching refers to the initial phage of overtraining syndrome and has been known as a physical fatigue which is mainly from metabolic imbalance. It has been known that overtraining also results in a loss of adaptability which may lead to an attenuation of exercise performance, sleeping disorder, central fatigue, neurohormonal changes, difficulty recovery to physical stress, and immunological changes. Additionally, overtraining syndrome is characterized by persistent fatigue, poor performance in sport due to the prolonged and strenuous physical training. Also, previous studies reported that endurance athletes experienced a high incidence of URTI during intense training and the post training. And also, high-performance athletes reported that suppression of cell mediated and anti-body mediated immune function. NK cell numbers were also reduced in the period of overtraining syndrome. Major components of prevention and treatment for the overtraining syndrome are screening, education, and detraining. Furthermore, the combination of these prevention and treatment strategies will be much helpful. Therefore, the current review will be helpful for athletes and individuals who are at the risk of overtraining syndrome.

  • Recently, golf courses have increased over the years because golf became popular leisure sport. Various environmental problems have been then issued by a golf course during constructing and running them. A problem of pesticide, which is serious among various environmental problems, from golf course has harmful effect on surrounding area and makes human suffer from acute and chronic diseases. Pesticides are used for the cost-effective managing of golf course and the amount of pesticides also increases as the number of golf course increase. Since the assessment of pesticides on near-by surrounding has been focused on water and soil media, studies related to atmospheric dispersion have been hardly attempted. The method to assess an impact of pesticide nearby agricultural production by the atmospheric dispersion using AGDISP(AGricultural DISPersal) model was developed and applied to the actual planned golf course located in Hongcheon, Gangwon. For implementing AGDISP, parameters were investigated from the golf course's land use planning map, pesticide spray device, Hong-Cheon weather station and etc. First of all, a kind of pesticide, a form of spraying pesticide, geographical features, weather data, and distance(golf course to plantation) were investigated to understand how to work these parameters in AGDISP. Restricted data(slope angle, droplet size distribution and solar insolation) sensitivity analysis of these parameters to estimate effect of pesticide nearby a plantation and a high relative contribution data of analyzed data was selected for input data. Ethoprophos was chosen as the pesticide used in the golf course and the amounts of pesticide deposition per annual agricultural productions were predicted. The results show that maximum amount of pesticide deposition through atmospheric dispersion was predicted $2.32{\mu}/m^2$ at 96 m where the nearest organic plantation exists. The residues of pesticide were also estimated based on the annul production of the organic and the deposition amount of the pesticide. Consequently, buckwheat, wheat and millet were likely to exceed maximum residue limits for pesticides in foods(MRL) and sorghum, corn and peanut were likely to exceed MRL by organic farming as well.

  • The 5 day workweek has become widespread, and more recently, the 40 hour workweek is planned to be implemented to the Korean industry by the government by 2012. It is possible that in the future, we may begin to complain about too much leisure, rather than too much work. There is a need then, for types options in leisure activity, brought about by personal choices and interests. The use of leisure time is a very personal matter. It is deeply related to types with the quality of life. Bagozzi (1981) developed a model discerning among attitude, intention and activity, that attitude affects behavioral intention, and behavioral intention affects activity. So, as behavioral activity has a deep relationship to behavioral intention, participation intention according to leisure types leads to participation in leisure activity. Sports activity and hobby and cultural activity appear to have high participation and it seems that this is reflected in behavioral attitude. Among the types of leisure satisfaction, sport activity satisfaction is associated with a more positive attitude to leisure than other types. With respect to background variables for attitude toward leisure according to leisure satisfaction, the biggest differences in attitude toward leisure were associated with sports activity.

  • This study had begun about the conflict between a lack of social adjustment and integration program for resident foreigners in Korea and a duplication of multicultural service in a specific area. This study was implemented through literature review and interview for analyses of the current status and problems of multicultural policy, subdivided into 3-stages model to reach the multiculturalism as multicultural policy process. The first stage suggested the unification of a channel for establishing a policies, reinforcing the functions of government ministries and the cooperation between the branches of the government. The second stage attempted to build the multicutural institutes network in a specific area unit, considering of the geographical and administrative environments. The third stage focused on the activities of individual organizations and proposed collaboration with library, school, support center for multi-cultural families, social service center, sport center, community center, and cultural facility. Additionally, 3-stages model emphasized on civic organization's role. This study was offered a meta-platform leaded by library community for sharing the information about planning and managing of multicutural programs and also mentioned significances for formulating multicutural policies. As a result, this study was presented and specified the 3-stages model to reach the multiculturalism, and verified the various considerations which have influenced the refinements of the multicultural policies as the demographic and geographical characteristics.
