The purpose of the study was to investigate the changes of blood components, acid-base equibilium and concentration of blood gas during boxing matches. Six varsity boxers were the subjects. The number of the RBC were significantly increased after 1st round (p<0.01) and the magnitude of the increase was reduced in accordance with succeeding rounds. The number of the WBC were significantly increased in accordance with succeeding rounds(p<0.01). The Hematocrit and the concentration of Hemoglobin were significantly decreased because of the increase of the number of RBC and decrease of the MCV (p<0.05). The concentration of the blood glucose were increase in accordance with succeeding rounds and the concentration of the blood glucose were shown the 71% of increase after 3 rounds, and also was significantly increased level than that of rest period. The plasma Albumin and total protein concentration were increased in compare with rest period. The plasma Albumin were significantly increased after 2 round but these were no significant differences in other rounds in contrast with rest period. The pH in the venous blood was significantly decreased in accordance with succeeding rounds(p<0.05), But the magnitude of the increase after 3th round was more higher than after 2nd round. The concentration of the bicarbonate and base excess were significantly decreased (p<0.01) in accordance with decreasing of pH and succeeding rounds. The Pco₂ venous blood was shown more increased after 2nd round, but was shown significant decreasing after 3rd round (p<0.01). The Pco₂ was increased in accordance with succeeding wounds and was significantly increased after 3rd round in Compare with Pco₂ O₂CT and O₂ SAT were increased in accordance with the incresing of Pco₂ succeeding round. The significant increase of O₂SAT in venous blood after 3rd round (p<0.01) was shown nearly the value of Po₂ of artrial blood, but the mechanism was not examinated in this study. The heart rate between rounds was increased in accordance with succeeding rounds, and the heart rate after 3th round was shown the load of maximal exercise(193 bpm).

양정수,홍완수 한국외식경영학회 2019 외식경영연구 Vol.22 No.2

Foodservice corporations have been increasingly conducting creating shared value(CSV) activities to pursue sustainability. In the domestic corporate environment where ‘win-win’ has become a core strategy for survival, importance of CSV activities that concurrently produce social and business value will further increase in corporate management. This study, therefore, attempts to acknowledge the importance of foodservice corporations’ CSV and provide the basic data necessary for corporations to set their CSV directions. The findings of the study were as follows: first, CSV has a significant positive effect on intention to visit; second, CSV influences sub-variables of corporate image, such as reciprocity, corporate reputation and social connectivity, indicating that CSV has a positive effect on corporate image; third, the mediating effects of reciprocity, corporate reputation and social connectivity which influence CSV’s effect on intention to visit showed that the intention to visit increased as CSV activities, reciprocity, and social connectivity increased. 외식기업은 지속 가능성을 추구할 수 있는 CSV 활동을 펼치고 있는데 ‘상생’이 중요한 기업의 생존 전략이 된 국내 기업 환경에서 사회적 가치와 비즈니스적 가치를 동시에 창출하는 CSV의 역할은 기업 경영에 있어서 앞으로 더 중요해질 것으로 예상된다. 이에 본 연구에서는 외식기업의 CSV의 중요성을 인식하고 외식기업이 CSV 방향을 설정하는데 중요한 기초자료를 제공하고자 한다. 연구결과로는 첫째, CSV는 방문의도에 유의한 정의 영향을 미치는 것으로 나타났다. 둘째, CSV가 기업이미지의 하위 변수인 호혜성, 기업평판, 사회적 연결감에 영향을 미치는 것으로 확인되었으며, 이는 CSV의 활동이 기업이미지에 긍정적인 영향을 미친다고 할 수 있다. 셋째, CSV가 방문의도에 미치는 영향에 대한 호혜성, 기업평판, 사회적 연결감의 매개효과에 대해서 기업의 CSV 활동이 높을수록, 호혜성이 높을수록, 사회적 연결감이 높을수록 방문의도는 높아지는 것으로 검증되었다.

Primary peritonitis usually refers to a bacterial infection of the peritoneal cavity without a demonstrable intra-abdominal source. Most cases occur in children with ascites resulting from nephrotic syndrome or cirrhosis. Rarely, it may occur in previously healthy children less than 7years of age, usually a girl. Distinguishing primary peritonitis from appendicitis may be impossible in patients without a history of nephrotic syndrome or cirrhosis. Accordingly, the diagnosis of primary peritonitis is made only at laparotomy. We report one case of primary pneumococcal peritonitis in a 27-month-old female who underwent explorative laparotomy to discover the cause of suspicious intestinal perforation and mechanical ileus. Later, pneumococci were cultured in blood and gram-positive diplococci were isolated from the pus of peritoneal cavity.

목 적: 가와사끼병의 발병 원인은 아직 확실히 알려지지 않았지만 여러 차례의 역학조사와 임상 고찰을 통하여 원인으로 감염성 인자가 관여한다고 예측되고 있다. 본 연구에서는 경남 지역에서 역학 조사를 시행하여 발병 원인으로서 감염성 인자를 지지하는 지를 비교 분석하였다. 방 법: 1995년 1월부터 1999년 12월까지 5년간 동부 경남의 울산 동강병원과 중부 경남의 마산삼성병원, 서부 경남의 진주 경상대학교병원에서 가와사끼병으로 진단된 환아 717명을 대상으로 하였다. 각 병원에 연령, 성별, 발병일, 진단일을 적은 설문지를 보내어 연구 기간동안 가와사끼병으로 진단된 환아의 정보를 후향적 방법으로 조사하여 본원에서 종합하여 분석하였다. 결 과 : 1) 연도별 발생자수는 1995년 151명, 1996년 140명, 1997년 134명, 1998년 136명, 1999년 156명으로 연도에 따른 큰 차이는 없었고, 4월과 7월에 높은 환자 발생을 보였다. 2) 동부 경남에서 연도별 환자 발생의 최고치를 보인 달은 각각 1995년에 4월과 7월, 1996년에 4월과 7월, 1997년에 7월, 1998년에 4월, 1999년에 4월과 7월로 나타났다. 3) 중부 경남에서 연도별 환자 발생의 최고치를 보인 달은 각각 1995년에 4월, 1996년에 4월, 1997년에 4월과 7월, 1998년에 7월, 1999년에 7월로 나타났다. 4) 서부 경남에서 연도별 환자 발생의 최고치를 보인 달은 각각 1995년에 11월, 1996년에 8월, 1997년에 10월, 1998년에 12월, 1999년에 11월로 나타났다. 결 론 : 동부 경남과 중부 경남은 매년 유사하게 4월과 7월에 높은 환자 발생 빈도를 보인 반면 진주 지역에서는 두 지역과 다르게 늦가을과 겨울에 환자 발생 최고치를 보였다. 결론적으로 경남 지역내에서 단일 감염성 원인의 파급으로 인하여 발병 될 것이라는 가설은 검증할 수 없었으나 동부, 중부 경남에서 보인 매년 유사한 월별 발생 빈도를 볼 때 감염성 인자가 내재 되었음을 시사하는 소견으로 볼 수 있다. Purpose : The aim of this study was to determine the epidemiology of Kawasaki disease in the Kyung Nam area and to evaluate whether the results of this epidemiological study could support infectious etiology. Methods : We sent a questionnaire to three training hospitals in the Kyung Nam area and retrospectively reviewed their medical records of Kawasaki disease from Jun. 1995 to Dec. 1999. Results : The total number of patients was 717 cases, with little differences of annual prevalence during the five years. In all cases, the monthly prevalence of Kawasaki disease was high in Apr. and Jul. At the eastern of Kyung Nam, the monthly prevalence was high in Apr. and Jul. in 1995 and 1996, Jul. in 1997, Apr. in 1998 and Apr. and Jul. in 1999. In the central area of Kyung Nam, the monthly prevalence was high in Apr. in 1995 and 1996, Apr. and Jul. in 1997 and Jul. in 1998 and 1999. In the western Kyung Nam, the monthly prevalence was high in Nov. in 1995, Aug. in 1996, Oct. in 1997, Dec. in 1998 and Nov. in 1999. Conclusion : In the eastern and central areas of Kyung Nam, the monthly prevalence of Kawasaki disease was similarly high in Apr. and Jul. However, in the western district, the prevalence was high in late fall and winter. We could not prove the hypothesis that Kawasaki disease occurred with the spread of single infectious agent, but the a nnually similar prevalence in eastern and central Kyung Nam supported the infection theory for the etiology of the disease.

A Simple and Rapid Method Based on Liquid Chromatography–Tandem Mass Spectrometry for the Measurement of α-L-Iduronidase Activity in Dried Blood Spots: An Application to Mucopolysaccharidosis I (Hurler) Screening

양정수,민혜경,오현주,우혜인,이수연,김정원,송정한,박형두 대한진단검사의학회 2015 Annals of Laboratory Medicine Vol.35 No.1

Background: We developed an analytical method to measure α-L-iduronidase (IDUA) activity in dried blood spots. This was achieved by using liquid chromatography coupled to tandem mass spectrometry (LC-MS/MS) with electrospray ionization in the positive ion mode. Methods: Chromatographic separation was completed using mobile phase involving water-formic acid and acetonitrile-formic acid over 2.8 min of run time on a column with a Kinetex XB-C18 (Phenomenex, USA). The detection of column effluent was performed using a Xevo TQ-S triple quadrupole mass spectrometer (Waters, USA) in the multiple-reaction monitoring mode. This method was verified with blank and control samples at four activity levels: base, low, medium, and high. Control materials were provided from Centers for Disease Control and Prevention (CDC). Results: Intra- and inter-day precisions were between 2.6% and 16.5% and between 7.9% and 17.0%, respectively. A correlative regression study on the IDUA activity in CDC-control samples performed to assess the validity of the developed method showed a highly significant linear association (r2=0.9976) between the calculated and CDC-reported values and an obvious difference in activity among the four levels. This reliable analytical method was applied to mucopolysaccharidosis I (Hurler) screening of patients under treatment (n=4) and in normal controls (n=129). IDUA activity ranged from 8.98 to 77.12 μmol/hr/L) in normal controls, and patients undergoing medical treatment showed low IDUA activity. Conclusions: This method had advantages of simplicity, rapid sample preparation, and liquid chromatographic separation, which efficiently inhibited ionization suppression induced by matrix effects in mass spectrometric detection.
