This study was performed to provide preliminary data for the development of a useful instrument to measure the effect of sex education. The study was conducted with the voluntary participation of 155 college students enrolled in the course "Sexuality and Relationship" at Y university in Seoul. At the end of that course, they were asked to write freely about the change they had experienced on sexuality. All meaningful statements were elicited and classified into 7 categories; "Change of Knowledge", "Enlightenment", "Change of Attitude on Sexuality", "Buildup of Ability", "Buildup of. Identity", "Change of Emotion", "Change of Behavior:' There were significant changes in the areas of knowledge(28. 6%), enlightenment(27.4%), and attitudes(20.3%) about sexuality among these 7 categories. The Change of Knowledge category consists of 3 areas: "concretion of knowledge", "increase of information", and "correction of misunderstanding." In the category of Enlightenment, total 12 areas are included: "sex role", "erception of lack of knowledge", "importance of family", "life plan", "parent role", "value of life", "equality", "sexual autonomy", "importance of sexuality", "freedom of sexuality", "perception of sexual problem", and "meaning of love." The Attitude Change category consists of 8 areas. These are "being natural", "being progressive", "being sensitive", "being truthful", "being expressive", "being cautious", "being responsible", and "being confident". The category of Buildup of Ability includes 4 areas: "problem solving", "sex education", "relationship", and "communication". The category of Buildup of Identity includes "sexual identity", and "value of sexuality". The Emotional Change category includes 3 areas: "positive feeling", "negative feeling", and "breaking from negative feeling on sexuality". The Behavior Change category includes "sex-related behavioral change". In conclusion, up to now most researches on sex education effect measures only changes of knowledge, attitude, and behavior. But we believe the changes in "Enlightenment", "Buildup of Ability", "Buildup of Identity", "Change of Emotion", should be included in addition to knowledge, attitude, and behavior in the development of an instrument to measure the sex education effects. And the effect of sex education should measure the degree of learning of autonomy, enlightenment, and ability of behavior and so on rather than studying the simple changes in sexuality.enment", "Buildup of Ability", "Buildup of Identity", "Change of Emotion", should be included in addition to knowledge, attitude, and behavior in the development of an instrument to measure the sex education effects. And the effect of sex education should measure the degree of learning of autonomy, enlightenment, and ability of behavior and so on rather than studying the simple changes in sexuality.ng the simple changes in sexuality.

( Eui Chang Choi ),( Soon Jung Choi ) 한국체육학회 2015 국제스포츠과학 학술대회 Vol.2015 No.1

Purpose: The purpose of this study was to examine what characteristics and qualities of a teacher bring out positive changes in students. In order to this, researcher investigated positive changes of students and PE teacher`s characteristics and qualities that promote students` changes. Method: This study used qualitative complex case study. Participants were 5 PE teachers who participate in community focusing on students` character development, and their 10 students. Non-participant observation and in-depth interview were used. In addition, open questionnaire was administered with 200 students. Collected data were analyzed using inductive thematic analysis. Triangulation, member checks, and peer debriefing were conducted to enhance the trustworthiness of this study. Result: First, character of students have changed in various way. Students internalized 4 virtues of In, Eui, Ye, Gi categorized as most comprehensive range. They made an effort to become those who are filled with love(In), justice(Eui), courtesy(Ye), wisdom(Gi). Second, positive change effects are not based on single dimension but it depends on overall dimensions such as health, wisdom, emotion, morality, and spirituality. Health as qualities of PE teacher is concerned with achieving excellence in sport performance and keeping in good shape. Wisdom is concerned with having knowledge about the methods of PE class and preparing, being well-informed of character education and applying it to PE class, and noticing and managing students` changes in character. Emotion is associated with believing relationship with student important and being contented with students` enjoyment. Morality is concerned with trying to become a whole person a good model. Spirituality is associated with cherishing PE, students, themselves, and god, and pursuing students` development to become a whole person. These characteristics and qualities of PE teachers influenced to students on the whole process such as preparation, execution, and reflection of PE classes. It showed a stronger influence on the students` character changes when PE teachers exert to reflect and compliment themselves. Conclusion: Character development in students is not based on teacher`s content knowledge and instructional techniques. Character of students can be positive only when PE teachers` wholeness involved on the whole. It should reflect to in-service education for PE teachers about students` character. Furthermore we must research more in depth about what types of qualities of teachers give students` change in some types of pathways.

Causes and Predictive Factors Associated with "Diagnosis Changed" Outcomes in Patients Notified as Tuberculosis Cases in a Private Tertiary Hospital

Kang, Byung Ju,Jo, Kyung-Wook,Park, Tai Sun,Yoo, Jung-Wan,Lee, Sei Won,Choi, Chang-Min,Oh, Yeon-Mok,Lee, Sang-Do,Kim, Woo Sung,Kim, Dong Soon,Shim, Tae Sun The Korean Academy of Tuberculosis and Respiratory 2013 Tuberculosis and Respiratory Diseases Vol.75 No.6

Background: The aim of our study was to evaluate the "diagnosis changed" rate in patients notified as tuberculosis (TB) on the Korean TB surveillance system (KTBS). Methods: A total of 1,273 patients notified as TB cases on the KTBS in one private tertiary hospital in 2011 were enrolled in the present study. Patients were classified into three groups: "diagnosis maintained", "diagnosis changed" (initially notified as TB, but ultimately diagnosed as non-TB), and "administrative error" (notified as TB due to administrative errors). Results: Excluding 17 patients in the "administrative error" group, the "diagnosis maintained" and "diagnosis changed" groups included 1,097 (87.3%) and 159 patients (12.7%), respectively. Common causes of "diagnosis changed" were nontuberculous mycobacterial (NTM) disease (51.7%, 61/118), and pneumonia (17.8%) in cases notified as pulmonary TB, and meningitis (19.5%, 8/41) and Crohn's disease (12.2%) in cases notified as extrapulmonary TB. Being older than 35 years of age (odds ratio [OR], 2.18) and a positive acid-fast bacilli stain (OR, 1.58) were positive predictors and a TB-related radiological finding (OR, 0.42) was a negative predictor for a "diagnosis changed" result via multivariate logistic regression analysis in pulmonary TB cases. Conclusion: Because of a high "diagnosis changed" rate in TB notifications to the KTBS, the TB incidence rate measured by the KTBS may be overestimated. Considering the worldwide trend toward increased NTM disease, the "diagnosis changed" rate may increase over time. Thus, when reporting the annual TB notification rate in Korea, the exclusion of "diagnosis changed" cases is desirable.

Skilled and experienced anestheia is of great importance for patients undergoing orthotopic liver transplantation, because of multiple preexisting medical problems in such patients as well as the intraoperative problems of rapid hemodynamic, metabolic, and coagulation changes. In this study, the intraoperative hemodynamic and laboratory data were analyzed in ten dogs that underwent an orthotopic liver transplantation procedure by veno-venous bypass using Biopump. Liver transplantation can be divided into three distinct periods: stage I, or preanhepatic stage, which begins with the induction of anesthesia and continues until cross clamping of portal vein and IVC; stage II, or anhepatic stage, which begins at the anhepatic time and continues until the donor liver is reperfused by the recipients circulating blood; and stage III, or postanhepatic stage, which begins at the time of reperfusion and continues until the end of surgical procedure. The hemodynamic changes at the time of IVC and portal vein cross clamping were decreases in CVP, PCWP, and pulmonary artery pressure in spite of using Biopump. The significant metabolic alternations during anhepatic stage were decrease in blood glucose levels and increase in blood lactate levels. The more significant hemodynamic changes occurred at the time of reperfusion. Systolic pressure decreased suddenly to 58±6 mmHg and cardiac output decreased to 1.08±0.1l L/min. However heart rate, pulmonary artery pressure, CVP, and PCWP did not change significantly. During stage III, hyperglycemia occurred quite frequently. Significant abnormal coagulation chages could not be found, probably because the dogs were healthy. In conclusion, during anhepatic stage, we have to compensate for alternations of fluid balance. At the time of reperfusion, we should prevent severe hemodynamic changes and treat them immediately if they occur. However, it seems that glucose administration is not necessary to the liver recipient during stage II because there is no significant hemodynamic depression e to hypoglycemia at this time and hyperglycemia occurs later

This study set out to evaluate the appropriateness of the height of a cycle saddle which was usually set based on a cyclist's experience and simple judgment. For this purpose, there was aroused a need to study what a cyclist's leg movements were according to the knee joint angle, that is, to study how a cyclist's leg joint angles and angular velocity would change at each pedaling. Seven male college cyclists were selected, and their pedaling movements were divided into four phases. The images were taped at 60fields/sec, using two video cameras. The KWON 3D 2.1 program was adopted to calculate and synchronize the 3D coordinates values which were calculated with DLT(Direct Liner Transformation), in order to analyze kinematical factors. The results were as follows: 1) There was found no difference between foot joint angles according to changes of knee joint angles in each phase. But it became clear that Phase 1 and 2 where the foot angle got bigger were the area where the foot joint was expanded and that Phase 3 and 4 where the foot angle got smaller were the area where the foot joint was bent. Accordingly, the area which gives a great indirect impact to the changes of foot joint angles is considered to be the first part of Phase 3 at which point the cycle of pedaling starts. 2) In terms of the difference of foot joint angular velocity according to knee joint angles, there was found a relatively stable deceleration in the decelerating area(Phase 3 and 4) while you could detect faster changes in the acceleration area(Phase 1 and 2) than in the decelerating area. 3) The changes in the angle difference of knee joints according to each knee joint angle showed almost similar patterns for every knee joint. But the patterns had the graph model of the opposite shape to that of the angle difference of foot joints. 4) The research went on to see what kind of difference the knee joint angle made as knee joint angular velocity changed. The changes were unlike the foot joint angular velocity and thus showed relatively slow deceleration and acceleration. And the higher the saddle was set, the bigger the difference of the angular velocity was. 5) The difference of hip joint angles according to knee joint angles made a graph pattern which showed no big correlation with the height of a saddle. 6) In considering how hip joint angular velocity would change according to knee joint angles, the higher a saddle was set, the bigger angular velocity was found in Phase 1 and 2, the area of joint expansion and the smaller angular velocity in Phase 3 and 4, the area of joint bending. Comparisons and analysis were made based on the results above mentioned. The conclusion was that the lower a saddle which was one of the three experiment conditions was set, the smoother the pedaling turned and the bigger the angular velocity was resulted. In other words, when you take a long road cycling with your saddle fixed at a little lower height than the average one, you will consume less physical strength and expect better performance.

N/A Dipyridamole is an agent that may be used to noninvasively evaluate coronary artery disease. The effect of dipyridamole infusion its generally related to its induced peripheral vasodilatory effect. In normal person, heart rate is generally increased slightly while blood pressure decrease, but the achieved double product and related myocardial oxygen consumption have no significant change. The purpose of this study is to examine the effect and side effect of dipyridamole, and to compare different response to dipyridamole among the patients. We evaluated 847 patients who underwent dipyridamole stress myocardial SPECT. 93.6% of them had induced hypotension 0.9% showed no change of blood pressure, 5.5% had increased blood pressure 8.3% had no change of pulse rate more than 10% of basal pulse rate. Among diabetes, 16.9% was not change of pulse rate, 6.7% in non-diabetes. There was no significant correlation between age and rate pressure product rest(RPPr), in patients without perfusion defects on SPECT(y=7.1x+48.4r=0.13 p>0.01). As increasing age, RPPs/RPPr was declined(y=-11.6x+68.9 r=0.17 p〈0.01), similar results were obtained in patients with perfusion defect. The size of perfusion defect on myocardial SPECT have no correlation between RPPr and RPPs/RPPr. The side effects of dipyridamole included chest pain and chest tightness, headache, abdominal pain, dizzness, nausea, and dyspnea. As increasing age, dipyridamole-induced cardiac work at rest was increased, cardiac response to dipyridamole was decreased.

N/A Objectives: With advances in transcranial ultrasound technology, transcranial color-code Doppler ultrasonography provides the anatomical location of basal transcranial vessel and their blood flow. To study of changes of cerebral blood flow, we measured continuously the blood flow velocity of middle cerebral artery by transcranial Doppler(2.5MHz) before and after sublingual administration of 0.6mg. nitroglycerin in twenty healthy young persons. Methods: Pulse rate and systolic and diastolic blood pressure and velocity of percussion(P), tidal (T) and dicrotic(Dc) wave, and diastole(Ds), velocity time integral(VTI), mean velocity(V), pulsatility index(PI) were measured. Results: Heart rate was increased, and systolic blood pressure was decreased significantly two minutes after administration of nitroglycerin. Diameter of outer margin of color Doppler spectrum was increased, and P, T, Ds, VTI and V were decreased significantly after two minutes. PI was increased significantly after two minutes, but returned to baseline level soon. Conclusion: We concluded that dilatation and decreased blood flow velocity of middle cerebral artery were resulted by nitroglycerin.

천연물이 간대사에 미치는 영향페 대한 연구의 일환으로 세계 전 지역에서 널리 사용되고 잇으며 우리나라에서도 사용빈도가 높으나 간염등 간질환 유발사레가 보고되고 있는 마황, 황금 및 샐제 임상에서 이들 생약과 복합해서 자주 사용죄고 있는 대황을 선정하여, 띠들 천연물의 투여가 간 대사에 미치는 영향을 살펴보았다. 대황,마황, 황금 수침액을 1.09/kg의 용량으로 럿드에 7일간 경구 투여하고,최종투여 24시간 후 랫드의 간을 적출하였다. 간 대사에 미치는 영향을 살펴보기 위한 모질약뿔인 7-etliokycournarin을 적출간에 과관류하면서 2시간동안 일정시간 간격으로 관류액을 채취하여 생성된 7-ethoxycoumarin의 대사체인 7-hydroxycoin, glucuronide 포합체, sulfate포합체를 대조군과 배교 관찰하였다. 또한 긴독성 지표로서 혈청 ALT, AST를 측정하였으며 적출관류간에 대해 lipid peronidation 정도를 살펴보고 ÷t직병리검사를 실시하였다. 대촹 투여군에서는 7-ethoxycoumarin의 gulcuronidation이 갛소하였고fP<0.01), 마황투여군에서는 7-ethoxycoumarin의 o-deethylation이 증가하였다(P<0.01). 이러한 7-ethoxycoumariu 대사의 변화가 대황, 마황에 의한 관련 효소의 생합성 증가/감소에 의한 것인지 여부를 살펴보고자 일착로 CYPIAI, Ct'P2Bl CDHA primer를 사용하여 적출관류간 소포체에서 mRNA level을 측정하였다.마황투옥군에서 CVPIAI mRNA level의 증가가 관찰되었지만 통계적으로 유의한 차이를 나타내지는 않았다. 또한 이들 천연물에 의한 간독성 유발여부를 비교 평가한 결과 혈청 ALT 및 AST는 대조군에 비하여 유의한 차이가 없었다. 그러나 만성 간염정도를 나타내는 지표인 ALT/AST ratio는 마황 투여군에ㅓ 대조군에 비하여 유으한 차이를 나타내었고 대황투여군에서 간소포체내 lipid Peroxidation(MDA production)이 대조군에 비해 증가하였다.반면 조직학적 관찰결과는 대조군에 비하여 유의한 차이를 나타내지 않았다. 이상의 결과를 요약하면 랫드에서 대황 투여에 의해 7-ethoxycoumarin gtucuronidation이 감소되었으며, 마황 투여에 의해서 7-ethoxycoumarin의 o-deethylation은 증가되었고 마창 투여군의 경우 이러한 효소의 활성증가는 CYPIA1 induction에 의한 것일 수도 있다는 가능성을 제시하고 있다. In recent 3rears, hepatotoxicity concerned with Ephedrae herba or Scutellariae radixadmiBistration was case reported and Rhei rhizoma is commonly used with them. Tn order to study theeffect of Rhei rhizoma, Ep]ledrae herba and Scutellariae radix on hepatic metabolism, we exalnined theeffect of those pretreatment on the metabolism of 7-ethoxycoumarin(EC). Water extracts(Ig/fg) ofRhei rhiaoma, Ephedrae tterba and Scutetlariae radix were admi3tistered orally to rats for T days,respectively. Livers were t:ten isolated and perfused with 100uM EC for 2 hours. The metabolites of EC,7-hydroxycoernarin, sulfate conjugate and glucuronide conjugate, were measured in the perfusates dur-ing perfusion. The amount of glucuronide conjvgates was decreased iB ahei rhizoma pretreated rats (p <0.01) and 7-bfdroxycournarin was increased in Ephedrae herba pretreated rats(p < 0.01). To examineTrhether the change of enByme activity is related to the induction ,or inhibition of enzymes concerned,we measured the change oif CYPIAt and CYPaBl mRNA level in the perfused rat liver, which are con-sidered to be EC specifie. However, CYPIAI and CYPEBI rnRNA ilevel were not found to be changedwith Rhei rhizoma nor I]3hedrae herba pretreatmen·t. We also assessed the hepatic toxicity of Rheirhizoma,.:phedrae herba and Scutellariae radix. The activity of ALT and AST was assayed at 34hrsafter 7 dfyt ndrninistratiofl and it was not found to be changed- Only the ratio of ALT over AST was in-creased in Epedrae herbs. pretreated rats(p < 0.05), which implies possible chronic hepatitis. Lipidperoxidation was increased in Rhei rhizoma treatment(p <0.05) , while histopathological examinationperformed after liver perfusion did not show any difference compared with vehicle treatmeut. Theseresutts suggest that Ephedrae herba pretreatment increases the o-deethylation of 7- ethoxrcoumariB inrats, which Inay be mediated by CYPIAI mRNA induction.
