This study investigated foot pressure patterns between experienced skiers and intermediate skiers during alpine skiing. Five experienced skiers and five intermediate skiers participated in this study. Foot pressure measurement system was used to measure vertical ground reaction force (vGRF) and contact area under the six plantar regions. Each participant was asked to perform basic parallel turns and carved turns on a $18^{\circ}$ groomed slope. Each right turn was divided into the initiation phase, the steering phase 1 and 2. For the initiation phase of the basic parallel turns, significantly greater contact area was found on the LRF and RRF of the intermediate skiers (p<.05) and significantly greater vGRF was found on the LRF of the intermediate skiers (p<.05). Also significantly greater vGRF and contact area were found on the LRF and RRF of the intermediate skiers at the steering phase 1 (p<.05) and on the LRF of the intermediate skiers at the steering phase 2 (p<.05). For the carved turns, significantly greater vGRF and contact area were found on the LRF and RRF of the intermediate skiers at all three phase (p<.05). On the other hand, significantly greater vGRF was found on the RFF of the experienced skiers at the steering phase 1 (p<.05). Also significantly greater vGRF and contact area were found on the RMF of the experienced skiers at the steering phase 2 (p<.05). In order to increase performance, we suggest that the intermediate skiers should be unweighted at the initiation phase and shift the body weight to the forefoot of the outer foot at the steering phase 1. Also, the outer ski should be loaded more than the both skis at the steering phase 1 and 2.

In Korea, elderly population aged 65 and older are about 5.0% and 10.7% in 1990 and 2009, respectively. Since elderly people may experience physiologic changes with aging and their pharmacodynamic and pharmcokinetic parameters also have been undergone changes, several adverse drug reactions can occur more frequently than young people. Especially, neuropsychiatric adverse drug reactions such as delirium and drowsiness endanger elderly patients more. The purpose of this study is to evaluate the outpatient prescriptions using drug causing delirium and drowsiness in elderly patients aged 65 and older. We retrospectively reviewed prescriptions for elderly patients collected from four community pharmacies from January 2nd to February 1st, 2010. One pharmacy was located closed to a general hospital, and others were located closed to a internal medicine or an ENT clinic. The each number of the collected prescriptions was followings; Group A (n=496) from internal medicine department of a general hospital; Group B (n=44) from ENT department of general hospital; Group C (n=144) from internal medicine clinic; Group D (n=110) from ENT clinic. In result, in Group A, the average number of prescribed drugs causing delirium or drowsiness per Rx was 2.38 In Group B, the average number of prescribed drugs causing delirium or drowsiness per Rx was 2.09 In Group C, the average number of prescribed drugs causing delirium or drowsiness per Rx was 2.51. In Group D, the average number of prescribed drugs causing delirium or drowsiness per Rx was 2.72. Especially, in Group D, the percentage of prescription that drugs causing delirium or drowsiness per Rx prescribed more than 3 is 52.73% In all the 4 groups, over the 60% of drugs causing delirium and/or drowsiness per prescription of elderly patients were prescribed. It means elderly patients take 2 drugs causing delirium and/or drowsiness among 3 drugs, which is very serious. Frequently prescribed drugs causing delirium and/or drowsiness were followings; GI agents, antitussives & expectorants, histamine H1 antagonist, analgesics, antibiotics. Among these drugs, GI agents was high raking in all the 4 groups, and pharmacists should caution elderly patients when counseling. In the internal medicine groups (Group A,C), drugs concerning chronic diseases were prescribed frequently. In conclusion, pharmacist's role is important. Pharmacists are well informed of the drugs causing delirium or drowsiness and it is important to explain about ADRs slowly and easily to the elderly patients that receive drugs causing delirium or drowsiness. And institutional device is needed. For example, when doctors prescribe drugs for the elderly patients, message is needed that supply some informations about drugs causing delirium or drowsiness.

Purpose: An outbreak of influenza virus is uncommon in neonatal intensive care unit (NICU). The clinical presentation of influenza virus infection in neonates is diverse. This study was aimed to report an outbreak of influenza A in a NICU and to investigate the clinical characteristics of influenza virus infection in neonates especially preterm infants during the 2011-2012 influenza season in Korea. Methods: We reviewed the medical records of 29 patients who were evaluated by respiratory virus multiplex reverse transcriptase-polymerase chain reaction (RT-PCR) at NICU of Kosin University Gospel Hospital during the 2011-2012 seasonal influenza outbreak in Korea. Results: Eleven patients (37.9%) were influenza A virus RT-PCR positive during the survey periods. They were all preterm infants and three of them had no symptoms. Eight patients had symptoms and it was fever (18%, 2/11), respiratory difficulty (72.7%, 8/11) without symptoms of upper respiratory infection, and gastrointestinal symptoms (27.3%, 3/11). The median duration of symptom was 5 days. There were differences of duration of admission at the test of respiratory RT-PCR, Clinical Risk Index for Babies (CRIB) score, use of mechanical ventilation, and use of dexamethasone before infection between influenza A virus RT-PCR positive and negative group. All 11 patients with influenza A were discharged without any complications. Conclusions: The symptoms of influenza A virus infection in the preterm infants is nonspecific. Influenza A virus should be considered as a possible cause of infection in NICU during the influenza season in the community.

Modern technology has lessened the physical demand of every activities. Thus, physical inactivity has led to a rise in ‘Hypokinetic diseases’. The prefix, hypo, means lack of and kinetic refers to movement. Individuals who do not exercise regularly are at greater risk of developing hypokinetic diseases such as coronary heart disease, hypertension, hyperlipidemia, obesity, musculoskeletal disease. Systematic exercise program defenses development of hypokinetic diseases. Exercise program bases on basic physical fitness test. The physical fitness evaluation is used to degree of Wellness of the individuals. It includes the evaluation of Health-Related Physical Fitness -musclular strength, muscular endurance, flexibility, cardiorespiratory endurance, body composition - and skill or sports related fitness -agility, balance, coordination, reaction time, speed. In present study, the authors investigated health-related physical fitness test result and questionnaire for 133 male and 71 female from Jannuary 16 to March 15, 1997. The purpose of this study is to observe relationship health related physical fitness and self-perceived health status. The results are as follows. 1. There were statistically significant differences in BMI, grip strength, back strength, muscular endurance, cardiorespiratory endurance, and flexibility between male and female subjects. Flexibility is higher in female than male subject, but Others are higher in male than female subjects. 2. There were statistically significant differences in grip strength, muscular endurance between 30s, 40s, and 50s group In both gender subjects, and In cardiorespiratoryendurance between the groups especially in Female subjects. 3. For male subjects, flexibilitywas measured lower in group who classified low level in self-perceived health status than group of others. Also, for female, subjects, Muscular endurance ＆ flexibility were measured. 4. It was shown that grip strength, back strength, and muscular endurance were significantly lower in group who have chronic diseases than normal group for Male subjects. But, For female subjects, all the component were statistically insignificant results between normal and disease group. 5. Both male and female subjects, there were Positive correlation among grip strength, back strength, muscular endurance, cardiorespiratory endurance, and flexibility but, negative correlation for age. Therefore, health-related physical fitness is very important component for Heath Promotion ＆ Wellness. Physical Fitness test is valuable test in health evaluation, health management and health promotion, so available for hospital, sports center, community health center, industrial field, school etc.

In order to survey the seasonal variation of the chemical composition of particulate matter of $2.5{\mu}m$ or less ($PM_{2.5}$), $PM_{2.5}$ was sampled from 8 February 2013 to 31 March 2014 in an industrial area of Chiba Prefecture, Japan. Chemical measurements of the sample included: ionic components ($Na^+$, $NH_4{^+}$, $Ca^{2+}$, $Mg^{2+}$, $K^+$, $Cl^-$, $NO_3{^-}$ and $SO_4{^{2-}}$), carbonaceous components - organic carbon (OC) and elemental carbon (EC), and water-soluble organic carbon (WSOC). Also, secondary organic carbon (SOC) was measured based using the EC tracer method, and char-EC and soot-EC were calculated from the analytical results. The data obtained were interpreted in terms of temporal variation. Of the overall mean value of $PM_{2.5}$ mass concentration obtained during the study period, ionic components, OC and EC accounted for 45.3%, 19.7%, and 8.0%, respectively. $NO_3{^-}$ showed a unique seasonal distribution pattern due to a dependence on temperature and absolute humidity. It was estimated that an approximate temperature of $14^{\circ}C$, and absolute humidity of $7g/m^3$ were critical for the reversible reaction of $NH_4NO_3(p){\leftrightharpoons}NH_3(g)+HNO_3(g)$. The amount of OC and EC contributing to the monthly $PM_{2.5}$ mass concentration was higher in autumn and winter compared to spring and summer. This result could be attributed to the impact of burning biomass, since WSOC and the ratio of char-EC/soot-EC showed a similar pattern during the corresponding period. From the comparison of monthly WSOC/OC values, a maximum ratio of 83% was obtained in August (summer). The WSOC and estimated SOC levels derived from the EC tracer method correlated (R=0.77) in summer. The high occurrence of WSOC during summer was mainly due to the formation of SOC by photochemical reactions. Through long-term observation of $PM_{2.5}$ chemical components, we established that the degree to which the above-mentioned factors influence $PM_{2.5}$ composition, fluctuates with seasonal changes.

The purpose of this study is to develop the first domestic professional hospice educational program. We investigated the present condition of Korean hospice education and analyzed the prerequisite need for a dedicated hospice course in the professional education process. Research was conducted between June and November 1996 for nursing professors teaching at each nursing education institute to find out how much hospice is being discussed and by whom, in which course it is being discussed, and also to find out the contents that needed to be included in the professional education process. From a total of 49 colleges(29 three year colleges, 20 four year colleges) out of 99, 162 nursing professors replied, the collection rate was 49.5%. The conclusions are as follows ; 1. The present condition of the hospice nursing education. 1) Whether hospice is included in the education program. \circled1 89.65% of 3 year colleges and 90% of 4 year colleges included hospice education in their education program. \circled2 In graduate studies three schools included hospice in their program and three schools expressed their plans to include hospice education 2) Hospice related education were commonly discussed in adult nursing(26.3%), fundamental nursing(22.8%), and psychiatric nursing(20.2%). In 3 year colleges its commonly discussed in the first and second year and in 4 year colleges it is taught in the second and third year. 3) Hospice related theory/practical education hours were averages of 6.5/7.0 hrs in 3 year colleges and 14.2/11.3 hrs in 4 year colleges. 4) The majority of professors in charge of hospice education were in the following order adult nursing, psychiatric nursing, and fundamental nursing. 5) The courses that are thought to be adequate to manage hospice related education were adult nursing(29.3%), community health nursing(21.7%) and the desired method of education was the method currently being used (36.5%). 2. The demand for hospice nursing education. 1) Over 70% demanded professional hospice education program, the highest demand was for the value and meaning of life followed by the role and qualification of the hospice team and the mental maintenance of a dying patient. 25 categories showed over 90% demand. 2) The highest demand was for the value and meaning of life (98.2%) and the lowest demand were for danjeon breathing(71.0%)and acupuncture(71.0%). 3) Other contents that need to be discussed in the professional hospice education program were hospice nursing, the attitude and reaction of death, bereavement care, and the prospects of hospice.

We have studied the eukaryotic plankton species diversity to compare the community structure of fresh and brackish waters in the lower reaches of the Nakdong River using metagenomic methods. We constructed 18S rDNA clone libraries of total DNAs extracted from environmental water samples collected at Mulgeum (MG100929, fresh) and Eulsukdo bridge (ES, brackish). Through the steps of colony PCR, PCR-RFLP, sequencing and similarity analysis, we discovered the diverse species composition of eukaryotic plankton. Total 338 clones (170 at MG100929 and 168 at ES) were analyzed, and then we found 74 phylotypes (49 for MG100929 and 25 for ES). From the phylogenetic analysis, we confirmed various eukaryotic plankton of broad range of taxonomic groups, including Stramenopiles, Cryptophyta, Viridiplantae, Alveolata, Rhizaria, Metazoa, and Fungi. We also found several unreported species in Korea and candidates of new taxonomic entities at levels higher than genus. Especially, the cryptic species diversity including unreported phylotypes of Pirsonia (Stramenopiles) and Perkinsea (Alveolata) suggests that the molecular monitoring method can produce new informative biological data in monitoring the changes in the Nakdong River Mouth ecosystem.

Background and Aim: Polymorphisms in methylenetetrahydrofolate reductase (MTHFR) are known to be associated with predisposition for certain cancers. This study aimed to evaluate the effects of lifestyle factors, family history and genetic polymorphisms in MTHFR C677T and A1298C on rectal cancer risk and possible interactions with lifestyle factors in Northeast Thailand. Methods: A hospital-based case-control study was conducted during 2002-2006 with recruitment of 112 rectal cancer cases and 242 non-rectal cancer patient controls. Information was collected using a structured-questionnaire. Blood samples were obtained for assay of MTHFR C677T and A1298C genotypes by polymerase chain reaction with restriction fragment length polymorphism (PCR-RFLP) techniques. Associations between lifestyle factors, family history and genetic polymorphisms v.s. rectal cancer risk were assessed using logistic regression analysis. Results: Subjects with frequent and occasional constipation had a higher risk ($OR_{adj.}$=14.64; 95%CI=4.28-50.04 and $OR_{adj.}$=2.15; 95%CI=1.14-4.06), along with those who reported ever having hemorrhoids ($OR_{adj.}$=2.82; 95%CI=1.36-5.84) or a family history of cancer ($OR_{adj.}$=1.90; 95%CI=1.06-3.39). Consumption of a high level of pork was also associated with risk ($OR_{adj.}$=1.82; 95%CI=1.05-3.15). Interactions were not observed between MTHFR and other risk factors. Conclusions: This study suggested that the risk factors for rectal cancer in the Thai population are bowel habits, having had hemorrhoids, a family history of cancer and pork consumption.

Overexcitability (OE) and social self-concept are the integral affective characteristics of science-gifted students. Overexcitability refers to sensitivity as an internal disposition to give a more often, longer and more intensive reaction to a wide variety of stimuli, and social self-concept refers to the way of behaving in society, especially at school in the case of students. The purpose of this study was to examine the overexcitability and social self-concept of science-gifted and non-gifted elementary school students. The subjects in this study were 135 gifted elementary students belonged to gifted education centers or gifted classes and 91 ordinary elementary students. An overexcitability test and a social self-concept test were conducted to the subjects, and the collected data were analyzed by SPSS. The findings of the study were as follows: First, the score of the science-gifted was significantly higher than that of the ordinary students in all sub-domain of OE (psychomotor OE, sensual OE, emotional OE, intellectual OE, emotional OE) and social self-concept. Second, the science-gifted students who attended gifted education centers and community gifted classes scored significantly higher than the ordinary students in overexcitability. Based on conclusions, implications for teaching the science-gifted were discussed.

Two experiments were conducted to investigate the effects of disodium fumarate on the in vitro rumen fermentation profiles of different substrates and microbial communities. In experiment 1, nine diets (high-forage diet (forage:concentrate, e.g. F:C = 7:3, DM basis), medium-forage diet (F:C = 5:5, DM basis), low-forage diet(F:C = 1:9, DM basis), cracked corn, cracked wheat, soluble starch, tall elata (Festuca elata), perennial ryegrass and rice straw) were fermented in vitro by rumen microorganisms from local goats. The results showed that during 24 h incubations, for all substrates, disodium fumarate increased (p<0.05) the gas production, and tended to increase (p<0.10) the acetate, propionate and total VFA concentration and decrease the ratio of acetate to propionate, whereas no treatment effect was observed for the lactate concentration. The apparent DM loss for tall elata, perennial ryegrass and rice straw increased (p<0.05) with the addition of disodium fumarate. With the exception of tall elata, perennial ryegrass and rice straw, disodium fumarate addition increased the final pH (p<0.05) for all substrates. In experiment 2, three substrates (a high-forage diet, a medium-forage diet and a high concentrate diet) were fermented by mixed rumen microbes in vitro. A polymerase chain reaction-denaturing gradient gel electrophoresis (PCR-DGGE) technique was applied to compare microbial DNA fingerprints between substrates at the end of 24 h incubation. The results showed that when Festuca elata was used as substrate, the control and disodium fumarate treatments had similar DGGE profiles, with their similarities higher than 96%. As the ratio of concentrate increased, however, the similarities in DGGE profiles decreased between the control and disodium fumarate treatment. Overall, these results suggest that disodium fumarate is effective in increasing the pH and gas production for the diets differing in forage: concentrate ratio, grain cereals and soluble starch, and in increasing dry matter loss for the forages (tall elata, perennial ryegrass and rice straw) in vitro, whereas its effect on changes of ruminal microbial community may largely depend on the general nature of the substrate.
