The Taekwondo being a martial sports, there are higher chances for the injury to occur than the non martial sports. Therefore, this study analyze the frequency, the area, the type, and the condition of the injury which are prone to occur in the Taekwondo matches; it is to help the Taekwondo players in prevention of the injury and in treatment. The subjects of this study were the 48 players (male 24, female 24) who participated in the final selection contest of the national team player on March 9 to 12, 1993. The data of the injury were obtained from the medical recoder staff and were analyzed to the frequency of the injury per match, the vulnerable area of the injury, the type of injury, and the condition of the injury with a gender difference. There were 24 matches for the male and 24 matches for the female, total 48 matches. Therefore, the total participation number of the players are the double of the match number. 1. The frequency of the injury per match was 18.3%(11/60) for male and 23.1%(12/52) for women. 2. The areas of the injury were ankle 36.4%(4), foot 18.2%(2), knee 18.2%(2), lower leg 18.2%(2), wrist 9.1%(1) in male; foot 33.4%(4), ankle 16.7%(2), knee 16.7%(2), lower back 16.7%(2), lower leg 8.3%(1), face 8.3%(1) in female. 3. The types of the injury were contusion 45.5%(5), sprain 27.3%(3), abrasion 9.1%(1), laceration 9.1%(1), tendon rupture 9.1%(1) in male; contusion 33.3%(4), sprain 33.3%(4), abrasion 16.7%(2), subcutaneous hemorrhage 8.3%(1), dislocation 8.3%(1) in female. 4. The condition of the injury were the unblocked attack 36.4%(4), attacking kick 27.3%(3), blocking a kick 18.2%(2), attacking punch 9.1%, impact with surface 9.1%(1) in male; attacking kick 33.3%(4), unblocked attack 25%(3), blocking a kick 25%(3), attacking punch 8.3%(1), impact with surface 8.3%(1) in female. This study shows that the injury from the Taekwondo matches occurred most in the lower extremity joints and the foot, and shows that the most of the injury types were contusion and sprain. Therefore, it is believed to be helpful to wear the proper fitting ankle or the knee protector and using other protective equipment to prevent the sports injury in the Taekwondo matches.

The purpose of this study is to provide basic information necessary for the cleaning of excavated costumes. For the purpose, these researchers reviewed previous records of the actual cleaning of excavated costumes and then implemented and documented the processes of cleaning the Yeosan Song's costumes excavated at Mokdal-dong, Daejeon, which could date back to the early and mid periods of Choseon Dynasty. The excavated clothes of the family provide good examples for comparing men's costume of the 15th century with men's and women's of the mid and late 16th century. The total quantity of excavated remains were 184 and textiles were cotton, silk, hemp, ramie, and union cloth. The clothing remains were processed through wet or dry cleaning in accordance with their fabric condition and the extent to which they were worn or polluted. In detail, the excavated costumes of the Yeosan Song family were cleaned in two stages. For wet cleaning, both anionic(LAS) and nonionic(Triton X-100) surfactants were respectively used as cleaning agents and for dry cleaning, a mixture of n-hexane and n-decane(the ratio of 4 to 6) and petrolic dry cleaning solvent were used. After first cleaning, some cotton, ramie and hemp which had still the stains were processed bleaching and silk which were good condition was processed dry cleaning with the organic solvent again.

This study was conducted to investigate the effect of dietary supplementation of zeolite on growth performance, carcass characteristics and fecal ammonia gas release in the finishing pigs. A total of 120 crossbred finishing pigs (50.2$\pm$1.4kg, Landrace$\time$Yorkshire$\time$Duroc) were assigned to 4 treatments and randomly divided into 12 groups. They were divided between early finishing period (50~80kg) and late finishing period (80-120kg). Finishing pigs were fed on a basal diet supplemented with 0, 1, 2 and 4% levels of zeolite. Average daily gain and feed conversion were significantly (P<0.05) improved by the dietary supplementation of 4% zeolite compared with other treatments during overall period. In the finishing periods, ammonia gas emission was reduced (P<0.05) in 4% zeolite treatment more than that of the other treatments. Carcass weight and back fat thicknesses were not affected by zeolite treatments. But, the appearance of A grade pork was increased by the dietary supplementation of 4% zeolite. Feed cost was linearly decreased by increasing the supplementation of zeolite. According to this study, 4% supplement of zeolite is suitable for the improvement of carcass quality and feed conversion, the reduction of fecal ammonia gas emission and feed cost per body weight gain.

The purpose of this study w8s to evaluate the effects of pulsed electromagnetic energy(Diapulse) and microcurrent on the wound healing in rabbits. 15 domestic rabbits were randomly assigned to the PRME(n=5). MC(n=5) and CON(n=91 group. Each rabbits were anesthetized with lidocaine HCL $2\%$. Skin wounds were created laterally on the back of IS domestic rabbits(33cm). From 24 hours after being injured, the rabbits of the PEME group were irradiated with an intensity of 3 at a 300 pulses per second, which were applied for 15 minutes every day during the 12 days. The MC group were stimulated with an intensity of $50{\mu}A$ at frequency of40 pulses per second, which were applied for 15 minutes every day during the 12 days. The CON group were not stimulated. The rabbits were sacrificed and the incised wound pans were processed appropriately for the light microscopic examination on the 3rd day, 6th day and 12th day before the beginning of wound treatment. The areas of wound were measured with metric graph paper. The results were as tallows. 1 The PRME and MC group compared with control group showed that wound closure rate increased on 6th, 12th day. 2. It was found that the CON group did not show a complete maturation and had a chronic inflammatory response. Judging from the irregularity of intercellular space and the loose alignment of connective tissue. these findings showed that wound healing was delayed. 3. It showed that inflammatory cells. fibroblasts and epithelial cells activity rapidly processed in the PEME group compared with the CON group. It was found that the PEMI; group showed a advanced remodeling of epithelial layer and a positive repair of connective tissue. 4. It showed that fibroblasts, epithelial cells and inflammatory cells activity rapidly processed in the MC group compared with the CON group. It was found that the MC group showed a improved remodeling of epithelial layer and a dense connective tissue.

This study was conducted to examined the effect of dietary supplementation of yellow loess on the growth performance and blood component profiles in pigs. A total of one hundred fifty three pigs (60 one weeks old piglets and 93 adult pigs). Piglets were randomly divided into 3 groups which were control, control + 0.5% yellow loess, control + 1% yellow loess. We measured body weight and weight gain among treatment group. Indeed, we obtained hematological data with WBC, RBC, Hb, Hct, MCV, MCH, MCHC, RDW, and PLT in all loess supplemented group compared to the control. Adults were divided into 2 group (control and control + 1% yellow loess) and serum albumin levels in 1% yellow loess supplemented group was significantly higher than the control group (p<0.01). Amount of crude fat in feces was significantly reduced in yellow loess supplemented group (p<0.001), but no differences were observed at crude protein and crude ash in both groups. In carcass weight and back fat thickness, no significant differences were observed between control and yellow loess supplemented groups. The carcass grade was improved by the dietary supplementation of yellow loess compared to the pig fed control. As a results, dietary yellow loess improves nutrient absorption and carcass grade.

Under the new system of 'Separation of pharmaceutical prescription and dispensing' in Korea, which was implemented in 2000, physician could not dispense a medicine, and outpatient should have a physician's prescription filled at a drugstore. After pharmacist makes up outpatient's prescription, National Health Insurance Service(NHIS) pay for outpatient's medicine to pharmacist, except an outpatient's own medicine charge. And NHIS only pay for outpatient's prescription fee to physician and, physician doesn't derive profit from dispensing medicine in itself. Nevertheless, if physician writes out a prescription with violation of 'Criteria for the Medical Care Benefits', NHIS clawed back the payment of outpatient's prescription and medicine from the physician or the medical institution which the physician belongs to. In the past, NHIS's confiscation was in accordance with 'the National Health Care Insurance Act, Article 52, Clause 1'. But, since 2006 when the Supreme Court declared that there was no legal basis on the NHIS's confiscation of outpatient's medicine payment, NHIS had put in a claim for illegal prescriptions on the basis 'the Korean Civil law, Article 750(tort)'. So, Many medical institutions filed civil actions against NHIS. The key point of this actions was whether the issuing outpatient prescriptions with violations of Criteria for the Medical Care Benefits constitute of the law of tort. On this point, the first trial and the second trial took different position. Finally the Supreme Court acknowledged the constitution of the law of tort in 2013. In this paper, the author will review critically the decision of the Supreme Court, and consider the relativeness between the legal effect of Criteria for the Medical Care Benefits and the constitution of the issuing outpatient prescriptions with violations of Criteria for the Medical Care Benefits as the law of tort.

Background Amniotic-fluid-derived stem cells and amniocytes have recently been determined to have wound healing effects, but their mechanism is not yet clearly understood. In this study, the effects of amniotic fluid stem cells and amniocytes on wound healing were investigated through animal experiments. Methods On the back of Sprague-Dawley rats, four circular full-thickness skin wounds 2 cm in diameter were created. The wounds were classified into the following four types: a control group using Tegaderm disc wound dressings and experimental groups using collagen discs, amniotic fluid stem cell discs, and amniocyte discs. The wounds were assessed through macroscopic histological examination and immunohistochemistry over a period of time. Results The amniotic fluid stem cell and amniocyte groups showed higher wound healing rates compared with the control group; histologically, the inflammatory cell invasion disappeared more quickly in these groups, and there was more significant angiogenesis. In particular, these groups had significant promotion of epithelial cell reproduction, collagen fiber formation, and angiogenesis during the initial 10 days of the wound healing process. The potency of transforming growth factor-${\beta}$ and fibronectin in the experimental group was much greater than that in the control group in the early stage of the wound healing process. In later stages, however, no significant difference was observed. Conclusions The amniotic fluid stem cells and amniocytes were confirmed to have accelerated the inflammatory stage to contribute to an enhanced cure rate and shortened wound healing period. Therefore, they hold promise as wound treatment agents.

Drynariae Rhizoma has been used for promotes mending of the sinews and bone, tonifies the kidney for such symptoms as weak low back and knees, and stimulates the growth of hair as a tinctute for alopecia in oriental medicine. This experiment examined the effect of an acetone extracts of Drynariae Rhizomas(GSB-1), its EtoAc fraction(GB-2) and n-buOH fraction(GSB-3), on hair growth activity of the C57BL/6L mice after topical application to skin. First, We examined on hair growth activity of extracts of Drynariae Rhizomas compare to control and 1 % minoxidil groups. Second, We investigated on the number of hair follicle and mast cells after topical application of extracts of the Drynariae Rhizomas to skin for 16 day. Third, We investigated immunoreactive density of vascular endothelial growth factor(VEGF), protein kinase C-${\alpha}$(PKC-${\alpha}$) and stem(mast) cell factor(SCF) in skin of C57BL/6N mice by immunohistochemical methods. The results were as follows : Hair growth effect of acetone extracts of Drynariae Rhizomas, its EtoAc fraction and n-BuOH fraction was observed in 98 %, 96 % and 60 % in hair removed skin area in 16 day respectively, Immunoreactive density of VEGF in skin of GSB-1 group was weakly stained compare to control group in 10 day, But GSB-2 and GSB-3 groups were mildy stained in bulge and root sheath of skin. Immunolocalization of SCF antigens was observed weakly stained density in epidermis, bulge, stem cells and dermal papilla of control gruop. but in experimental group, immunoreactivity of SCF antigens was observed mildly stained density in bulge, epidermis and root sheath of GSB-1 gruop, heavily stained density in epidermis, bulge and root sheath of GSB-2 and GSB-3 groups to the hair removal skin of C57BL/6N mice on day 10. These experiment suggest that acetone extracts of Drynariae Rhizomas and its EtoAc fraction may be used for topical treatment of alopecia areata.

Objectives: The purpose of this study is to provide basic data for the improvement of the working environment for health prevention and related countermeasures for shift workers. This study was conducted based on the Fifth Korean Working Conditions Survey (KWCS), which analyzed the health effects of shift work forces and compared them with preceding studies. Methods: By analyzing secondary rates using raw data from the 5th KWCS, 4,870 (9.7%) of the 50,184 total study subjects were divided into shift work and 45,314 (90.3%) non-shift work groups based on the response to shift status. Variables that could affect work health issues were identified and corrected. A cross-analysis was conducted to examine demographic characteristics (gender, age, and education level) of the workers and occupation characteristics (monthly net earnings, employment type, occupation, working period up to now, workplace scale, type of work system, and weekly working hours). In order to find the work health issue ratio between the shift and non-shift work groups, logistic regression was analyzed and the association with health problems according to shift type by gender was looked at through cross-analysis. Results: According to the surveys conducted from the 1st KWCS (2006) to the 5th KWCS (2017), the proportion of shift workers continued to increase. Also, muscular pains in the lower limbs (hips, legs, knees, feet, etc.) (OR=1.135, 95%CI 1.031-1.251), headaches, eyestrain (OR=1.580, 95% CI 1.428-1.748), anxiety (OR=1.715, 95% CI 1.402-2.099), difficulty falling asleep (OR=1.391), and other problems (OR=7.392) were reported. In addition, back pain, muscular pains in shoulders, neck and/or upper limbs, muscular pains in lower limbs (hips, legs, knees, feet, etc.), headaches, eyestrain, depression, anxiety, overall fatigue resulted in significant results for both male and female shift workers. Depression and anxiety were higher in female shift/circulation compared to males. Conclusions: The social nets for the health and safety of shift workers should be explored in a variety of ways, including management and supervision of shift sites, attempts to reorganize and improve the shift system, development of workers' health recovery programs, promotion, systematic treatment, and compensation systems.
