The purpose of this paper is to select 7 male athletes and female athletes of high school, and to compare their active potential differences of upper arm muscles according to characteristic of a racket. the results obtained are as follows: 1. According to the accumulative distribution rate of racket material, graphite and wood material show better efficiency in case of brachio radialis muscle of male athletes, but the racket material shows no constant efficiency in brachii radialis muscle of female athletes. In case of flexor carpi radialis muscle, wood material provides better efficiency only for male athletes. In case of triceps brachii muscle, wood material gives better efficiency to males athletes and steel material gives better efficiency to females athletes. Especially in case of biceps brachii muscle, neither male nor female athletes are influenced by racket materials at impact. 2. In the muscle load rate according to racket material, wood has the highest muscle active potential and graphite has the lowest active potential. Therefore, graphite is thoght to be better in the efficiency of muscle load rate.

양식어류의 세균성 질병 치료약제로서 사용량이 증가하고 있는 NFX의 정량분석 방법을 확립하고, 사육수온과 관련된 NFX의 어체내에서 흡수, 분포, 배설 등 NFX의 합목적적 사용 방법 설정에 필요한 약물동태학적 요인을 조사하였다. 수온에 따른 NFX의 어체 내에서의 혈중최대 농도는 뱀장어에서는 유의적인 차이는 없었으나 잉어에서는 혈중최대농도가 23℃에서 유의적으로 높게 (p〈0.05) 나타났을 뿐만 아니라 NFX의 흡수 및 배설속도정수, 최대혈중농도 도달시간 등 어종별, 수온별 약물동태학적 요인에 차이가 있었다. 이러한 결과로 NFX의 효과적인 사용방법과 휴약기간 설정을 위하여 어류의 사육환경과 관련된 임상 약물동력학적 특성을 충분히 고려하여 결정되어야 할 것으로 판단된다. Effects of Temperature on the pharmacokinetics of norfloxacin(NFX) were studied in the cultured carp, Cyprinus caripo, and cel, Angulla japonica, using high performance liquid chromatography(HPLC) originally developed for quinolone determination in livestocks. Pharmacokinetics of NFX was apparently affected by amibent water temperature. In a two-compartment model for carp after oral dosage of 20㎎/㎏, K01 at 13℃ and 23℃ were 2.60 and 5.20/hr, respectively. In carp the K_(w), T_(max) and C_(max) for carp at 13℃ were 13.30/hr, 17.44 ug/ml and 7.00 ug/ml, respectively. The corresponding values at 23℃ were 3.93/hr, 15.40㎍/㎖ and 9.44 ㎍/㎖, respectively. The AUC and T_(1/2) were 355.66 ㎍:hr/㎖ and 12.70 hr at 13℃ and 417.24 ㎍:hr/㎖ and 13.86 hrs at 23℃, respectively, Similar trends were revealed in the NFX pharmacokinetics of cel kept under the two water temperature regimes after oral NFX dosage of 20 mg/kg. These pharmacokinetical results have some implication in the optimal usage of recently introduced antibacterials in farmed fish, which were originally adapted for poultry and mammalian species.

Sports technology encompasses a wide range of disciplines from biomechanics to engineering. As a consequence, researchers working in sports technology find that their work falls neither in the field of traditional sports nor in mainstram engineering. Also Sports Engineering is an international journal publishing original papers on the application of engineering and science to sport. The journal intends to fill the niche area which lies between classical engineering and sports science and aims to bride the gap between the analysis of the equipment and of the athlete. Area of interest include the mechanics and dynamics of sport, the analysis of movement, instrument equipment design, surface interaction, materials and modeling. These topics may be applied to technology in almost any sports. The Sports Engineering will be of particular interest to Engineering, Physics, Mathematics and Sports Science Departments and The International Sport Engineering Association(ISEA) will act forum where research, industry and the sports sector can exchange knowledge and innovative ideas.

Objectives : This study is aimed at determining how the reliability of the results of the Korean Personality Inventory for Children(KPI-C) is affected according to the results of Minnesota Multiphasic Personality Inventory(MMPI) of the mothers. It is also intended to determine the mothers’ characteristics to considered at the interpretation or evaluation of the results of the test and investigate the correlation between the psychological problems of the mothers and their children. Methods : The subjects of this study were 43 mothers whose children visited the psychiatric department at Dongsan Hospital, Keimyung University from August 1998 until Jun 1999. They were administered with both MMPI and KPI-C Inventory. They were sorted into two group ; diagnosis consistent group and diagnosis inconsistent group depending on whether or not the KPI-C results mothers reported matched the clinical diagnosis of children. The motehrs’ variables and the results of MMPI were compared between the two groups. The correlation of MMPI and KPI-C was also studied. The statistical analysis was conducted using Independent samples t-test, χ^2-test, and Person correlation analysis. Statistical significance was p<0.05. Results : 1) In the whole group, the diagnosis consistent group was 29 people(67.2%) and the diagnosis inconsistent group was 14 people(32.8%). 2) The mothers’ MMPI results of the two groups belonged to the normal range. 3) There was no significant difference between the two group in their age, educational level, and job. 4) In comparing MMPI of the groups, the diagnosis inconsistent group showed significantly higher scores in L and K scales, and the diagnosis consistent group had higher scores in F, Hs, D, Hy, and Pa scales. 5) The correlation analysis of the validity scales of MMPI and the scales of KPI-C showed significantly negative correlation in the L scale f MMPI and FAM scale of KIP-C, K scale of MMPI and F, SOM, DLQ, PSY scales of KPI-C, On the other hand, the analysis showed significantly positive correlation in the K scale of MMPI and ERS scale of KPI-C, F scale of MMPI and DEP, SOM scales of KPI-C. 6) The correlation analysis of the clinical scales of MMPI and the scales of KPI-C showed significantly positive correlation in the Hs scales of MMPI and F, ANX, DEP, SOM of KPI-C, D scales of MMPI and ANX, DEP, SOM SOC, of KPI-C, Hy scales of MMPI and F, ANX, DEP, SOM, HPR, FAM scales of KPI-C, Pd scales of MMPI and DEP, SOM, FAM scales of KPI-C. It also showed significantly positive correlation in the Pa of MMPI and ANX, SOM scales of KPI-C, Pt scales of MMPI and PDL, ANX, DEP, SOM, FAM, PSY scales of KPI-C, Sc scales of MMPI and F, DEP, SOM, FAM, PSY scales of KPI-C, Ma scales of MMPI and F, SOM, FAM scales of KPI-C, Si scales of MMPI and SOM scales of KPI-C. On the other hand, the analysis showed significantly negative correlation in the Hs, D, Hy, Pt, Sc scales of MMPI and ERS scales of KPI-C. Conclusion : It is shown that the characteristics of the mothers’ personality have important effects on the perception of their children’s problems. In particular, the stronger the mothers’ defensive characteristics are, the lower the reliability of their perception of the children’s problems. On the other hand, the reliability is high when the mothers acknowledge their problems and perceive their children’s responses sensitively. Accordingly, it will hereafter be necessary to consider the characteristics of mothers’ personality at the interpretation or diagnosis of the results of children’s evaluation that mothers report. It is also shown that there is a significant correlation between the psychological problems of the mothers and their children.

소아의 악골내 발생한 낭종의 외과적 처치

김재곤,김영진,김미라,백병주 대한소아치과학회 2001 大韓小兒齒科學會誌 Vol.28 No.1

악골의 낭종은 크게 치성과 비치성으로 구분되며 치성낭은 치성기관이나 그 잔존 세포성분과 관련되어 주로 골내에서 발생한다. 비치성낭종은 과거에는 태아의 발육중 상피의 봉입이나 융합선을 따라 존재하는 상피잔사가 증식하여 낭성변형을 일으킨다는 설이 유력하였으나 현재에는 이러한 태아의 발육 동안 상피의 봉입은 일어나지 않는 것으로 보고 있다. 함치성낭은 미맹출 치아와 관련되어 발생하고 상피의 전암 가능성이 있으므로 가능한 빨리 제거하도록 하며 조대술이나 적출술이 이용될 수 있고 간혹 원인치의 발거가 추천된다. 비구개낭은 가장 일반적인 비치성낭으로 상악 중절치 사이에 경계가 명확한 방사선 투과상으로 나타난다. 적출술과 조대술로 치료할 수 있으며 전암 가능성이나 재발은 드물다. 본 증례에서는 전북대학교 병원 소아치과에 내원한 아동의 악골내 발생한 낭종을 외과적으로 제거한 후 다음과 같은 결론을 얻었다. 1.함치성낭의 환아에서, 원인 치아를 보존하고 완전 적출술로 병소를 제거한 후 경과를 관찰한 바 영구치의 정상적인 맹출이 이루어졌다. 2.비구개낭을 치료시, 인접치아의 생활력에 대한 정확한 진단과 그에 따른 치료법의 선택으로 불필요한 근관치료를 피할 수 있다. 3.향후 비구개낭의 환아의 관련치에 대한 계속적인 관찰이 필요하리 사료된다. 4.악골내 방사선 투과성의 병소를 치료시, 정확한 감별진단과 적절한 치료법의 선택이 중요하다. The Dentigerous cyst is reported to be one of the most common lesions of the jaw. It is derived from reduced enamel epithelium that surrounds the crown of an unerupted tooth. Dentigerous cysts usually remains asymptomatic and presents as well-circumscribed radiolucencies surrounding the crown of a tooth. Most dentigerous cysts are treated by surgical enucleation or marsupialization of the cyst to allow eruption of the permanent tooth. The nasopalatine duct cysts derived trom the islands epithelium remaining after closure of the embryonic nasopalatine duct. The cyst presents as a well-circumscribed oval or heart-shaped radiolucency located in the midline of the anterior maxilla between the roots of the central incisors. Treatments is by surgical enycleation, employing a paltal approach. This report present two cases. One case was diagnosed with dentigerous cyst and treated by enucleation. 12Months later, affected second premolar was erupted normally. The other case was diagnosed with nasopalation duct cyst. Histological examination of the enucleated cyst confirmed a nasopalatine duct cyst. There was no recurrence during follow up period.
