Purpose: Purposes of this study were to understand the current trends on complementary therapy in relieving chemotherapy-induced nausea and vomiting and to suggest the future research direction. Method: Subjects were selected on CINAHL, MEDLINE, Korean Academy Data Base from 1980 to 2001 which used nausea, vomiting, chemotherapy and complementary therapy as key words in experimental studies. Eight korean articles and twenty-one international articles were analyzed in terms of general characteristics, research methods, and types of complementary therapy. Data were analyzed by using descriptive statistical methods. Result: Since 2000, researchers have more actively used complementary therapy. In subject characteristics, mean age was 35.5 years old, 45% of the researchers were performed with high level of incidence of chemotherapy induced vomiting, 14% of them set limit of consecutive cycle during research, and 65% of them did not comment the selecting criteria of sample. About 60% of them were designed post-test only control group: 35% used INV by Rhodes, 31% used Likert scale, and 24% used VAS for dependent variable. Muscle relaxation therapy was mostly applied for relief of nausea and vomiting. Conclusion: Further studies will be needed to control extrinsic variables affecting nausea and vomiting in research design and to accumulate evidence with studies applying various complementary therapies.

Objectives: This study analyzed the difference in color caused by different thickness in enamel layer of composite resins when applied with single and layering placement technique, and evaluated if the results agreed with the shade guide from the manufacturers to verify reliability of the color matching process of the manufacturers. Materials and Methods: For single composite resin samples, 6 mm diameter and 4 mm thickness cylindrical samples were fabricated using Ceram-X mono (DENTSPLY DeTrey) and CIE L*a*b* values were measured with spectrophotometer. Same process was done for layering compositie resin samples, making 3 dentinal shade samples, 4 mm thickness, for each shade using Ceram-X duo (DENTSPLY DeTrey) and enamel shade resins were layered in 2 mm thickness and CIE L*a*b* values were measured. These samples were ground to 0.2 mm thickness each time, and CIE L*a*b* values were measured to 1 mm thickness of enamel shade resin. Results: Color difference (△E*) between single and layering composite resin was 1.37 minimum and 10.53 maximum when layering thicknesses were between 1 mm and 2 mm and 6 out of 10 same shade groups suggested by manufacturer showed remarkable color difference at anythickness (△E* > 3.3). Conclusion: When using Ceram-X mono and duo for composite resin restoration, following the manufacturer's instructions for chossing the shade is not appropriate, and more accurate information for Ceram-X duo is needed on the variation and expression of the shades depending on the thickness of the enamel.

The costumes have been changed and developed with the development of the mankind. Also the color of the costume reflect the culture of the times and change. Furthermore the color of the costume has been used as symbol of social status. This study analysed the restrictions of color in the sumptuary of the western costume. The relations between the symbolic meaning of color and the sumptuary of the costume color were analysed through a literature survey. On the western costume sumptuary law, the major restriction colors were red, purple and violet. These were used only for governing class who have the Power and authority. Especially purple was used only for royal family. The symbolic meanings of color are given to costumes of specific social status. The color of the costume was related to the symbolic meanings of a specific color in the times and societies.

연구목적 : 농촌지역 초등학생의 주의력결핍-과잉행동장애와 학습장애, 정신지체의 유병률을 조사하고, 보다 효과적인 장애아동 발견방법을 구하기 위해 연구를 계획하였다. 방 법 : 경기도 일개 군내 5개 면의 6개 초등학교, 1,256명에서 전체 학생을 대상으로 교사가 설문지를 작성한후 이를 통해 1차 선별하는 전수(total population) 조사방법과 교사가 직접 1차 선별하는 핵심요원(Key informant) 조사방법을 이용해 문제아동을 선별하였고, 대상아동은 현장을 방문해 정신과적 면담이나 지능검사를 통해 확진하였다. 결 과 : 1) 유별률은 주의력결핍-과잉행동장애가 1.99%, 학습장애가 0.40%, 경도이상의 정신지체가 2.23%이었다. 2) 전수 조사와 핵심요원 조사를 비교하면, 전수 조사의 경우 경도 이상의 정신지체의 유병률이 유의하게 높은 것(전수 조사 3.29%, 핵심요원 조사 1.23%) 외에 핵심요원 조사와 유별률에서 유의한 차이는 없었다. 핵심요원 조사는 주의력결핍-과잉행동장애와 정신지체 등에 의한 학습부진의 양성 예측도가 전수 조사에서 사용된 파탄적 행동장애 평정 척도(Disruptive Behavior Disorders Rating Scale, DBDRS)나 학업 수행 평정 척도(Academic Performance Rating Scale, APRS)보다 높았다(DBDRS : 전수 조사 17.33%, 핵심요원 조사 41.67% ; APRS : 전수 조사 39.22%, 핵심요원 조사 44.44%). 진단 받은 아동만을 비교할 때 두 집단의 질병분포에서 유의한 차이는 없었다. 3) 부모와 교사가 다같이 아동의 문제를 인식하고 있을 때 실제 장애의 가능성이 높았다. 결 론 : 조사된 시점유병률은 주의력결핍-과잉행동장애가 1.99%, 학습장애, 정신지체가 각각 0.40%와 2.23%였다. 양성예측도와 진단별 일치도로 비교할 때 핵심요원을 이용한 조사가 장애아동 발견에 보다 효율적이었다. 장애아동 발견에 있어 교사 혹은 부모의 단일 경로의 정보는 신뢰도가 상대적으로 낮았고 두 경로를 합쳤을 때 신뢰도가 더욱 높아짐을 볼 수 있었다. 이 연구의 결과는 우리 나라 초등학생에서 주의력결핍-과잉행동장애와 정신지체의 유병률을 조사했다는 의의와 함께, 향후 학교 대상의 역할조사에서 핵심요원 조사방법의 유효성을 증명하는 것이다. Objectives : We atlempted to determine the prevalence rate of attention deficit-hyperactivity disorder, learning disorder, and mental retardation of elementary school children in a rural area, and to evaluate a cost, and time-efficient method for identifying of children with such disabilities. Methods : We studied 1,256 children from 6 elementary schools in a rural aiea using used two-stage design. At the first step, we used the key informant and the total population survey methods for identifying children with disability. Teacher checklists were used as screening instru-ments in total population survey. And at the second step, child interview and KEDI-WISC were employed to make diagnoses. Results : 1) The prevalence rate of attention-deficit/hyperactivity disorder(ADHD) was 1.99%. The prevalence rates of learning disorder(LD) and mental retardation(MR) were 0.40% and 2.23%, respectively. 2) The prevalence rate of MR was significantly higher in total population method compared with key informant method(3.29% vs. 1.23%). Other comparison of prevalence rates in two methods was not significantly different. Positive predictabilities of ADHD and learning disabilities by key informants were higher than by DBDRS and APRS, the checklists used in total population methods. 3) The probability of illness was much higher when the teacher and parents reported the problems of child concurrently. Conclusions : The prevalence rate of ADHD in elementary school children in the rural area was 1.99%. And the prevalence rates of LD and MR were 0.40% and 2.23%, respectively. Key informant method was more effective compared with total population survey in positive predictability and diagnostic concordance, In identifying children with disabilities, the combined data from teacher and a parent was most reliable.

We intended to know that the result of color duplex ultrasonography corresponded to that nocturnal penile tumescence rigidity in the diagnosis of erctile dysfunction. We performed both color duplex ultrasonography and nocturnal penile tumescence rigidity in 15 erectile dysfunction men. Colr duplex ultrasonography was done with a 7 MHz. color Doppler unit after intracorporeal pharmacological injection and measured maximal arterail diameter, peak systolic velocity, end-diastolic velocity and the results were compared with rigidity and tumescence in nocturnal penile tumescence rigidity using RigiScan. The positive predictive value, negative predictive value, sensitivity, specificity, overall accuracy of color duplex ultrasonography was reasonable when the result of color duplex ultrasonography was compared with the that of nocturnal penile tumescence rigidity. According to this results, color duplex ultrasonography could not only predict but also correspond to nocturnal penile tumescence. Therefore, we suggest that color duplex ultrasonography can relpace nocturnal penile tumescence rigidity if psychogenic and neurogenic erectile dysfunction are distinguished by history and neurologic examination.
