In the mode choice analysis, since SP experiments present respondent with various hypothetical alternatives, which are produced by a combination of a number of different attribute levels, and ask them to indicate a preference, it is possible to analyze travel behavior under a situation of potential environment change such as proposed alternative mode of transportation. This study is to compare stated preference (SP) data with transfer price (TP) data by comparison of commulative transfer ratio from passenger car into medium rail transit. For this analysis, we assumed subway operations in the Gwang-Ju, and set up a choice-set of hypothetical options based on Experimental Design Method. As the result, the preference of same set of individuals by SP and TP questions might not be consistent with each other. This means that stated preferences are changable by difference of survey merhods. The updating of SP responses by the ultimatic condition of TP data also contributed the higher internal validity of SP model.

Most models and analysis of urban travel behavior focus on trying to explain variations in travel behavior of different behavior in terms of the characteristics of those individuals and their environment. Also, the analysis is typically based on a single day record of each individual' travel. But, developments in travel behavior analysis are leading to a greater awareness of the need to examine day-to-day variability in travel behavior. This paper analyzed dynamic characteristics, intrapersonal variability, and inter personal variability in urban travel behavior using activity diaries collected by 7 consecutives days in Gwangju. The analysis shows that, interpersonal variability as well as intrapersonal variability cannot be neglected in day-to-day variability of travel behavior.

이 연구는 각 유형의 부정교합과 중심교합위-중심위 변위량 간의 상호관련성을 구명하기 위하여 시행되었다. 각 부정교합자 군에서 중심교합위-중심위 변위를 3차원적으로 비교 평가하고, 각 안면골격 형태의 특징에 따른 변위량의 차이 유무를 분석하고, 각 유형의 부정교합 골격형태에서 중심교합위-중심위 변위와 두개안면골격 계측요소간의 상관성을 검정하였다. 242명의 부정교합자를 대상으로 중심교합위 상태에서 얻어진 측모두부X선규격사진을 계측하고 이들을 수평적, 수직적 관계에 의하여 9군으로 분류하였다. 또한 이들로부터 중심위와 중심교합위에서의 교합기록을 채득하고 face-bow로 안궁이전을 한 뒤 석고모형을 교합기에 중심위 상태로 탑재하였다. CPI를 이용하여 중심위와 중심교합위의 하악과두위치를 측정하고 이들과 각 군의 측모두부X선규격사진 계측치와의 상관성을 검정하기 위하여 통계처리한 결과 다음과 같은 결론을 얻었다. 1. 중심교합위-중심위 변위의 양과 방향에서 좌측과 우측은 중등도의 상관관계를 보였으며 전후방보다는 상하변위의 좌·우측 상관성이 다소 높았다. 2. Ⅱ급 부정교합군이 Ⅰ급과 Ⅲ급 부정교합군에 비해 좌우측간의 중심교합위-중심위 변위가 높은 상관관계를 보였다. 3. 각 부정교합군에서의 중심교합위-중심위 변위 유형은 유의한 차이가 없었다. 4. 중심교합위 상태의 측모두부X선규격사진상에서의 안면골격의 형태요소와 중심교합위-중심위 변위간에는 상관성이 적었다. 5. Ⅱ급 brachyfacial skeleton과 Ⅲ급 mesofacial skeleton의 일부 계측치에서 CPI수치를 예측할 수 있는 항목들이 나타났다. 중심교합위-중심위 변위의 양과 방향은 특정한 안면형태요소와는 무관하며 하악과두의 위치변이는 부정교합양태나 안면골격형태와 관계없이 발현되었다. The present study was performed to prove the relationship between CO-CR discrepancy and facial skeletal type. In this study, 242 subjects were randomly selected and devided into 9 groups(devided into class Ⅰ,Ⅱ, Ⅲ by ANB and each one devided into dolicho-, brachy-, mesofacial skeleton by Ricketts' vertical index). Lateral cephalometric radiographs with the mandible in centric occlusion were taken and measured and CO and CR bites were registered on all subject. Diagnostic casts were mounted on Panadent articulator using an estimated face-bow and centric relation bite registration. The amount and direction of CO-CR discrepancy present was recorded using a Condylar position Indicator(CPI) and a centric occlusion wax bite registration. CPI measurements and cephalometric measurements were statistically analyzed. The finding of this study can be summerized as follows: 1. There is little correlation between right and left sides for magnitude or direction of CO-CR discrepancies. The correlation between the magnitude of CO-CR discrepancy of left A-P and right A-P is higher than that of left S-I and right S-I. 2. Correlation of Class Ⅱ malocclusion group was higher than that of the other groups between the magnitude of Co-CR discrepancy of left CPI and right CPI. 3. There is no difference between the pattern of Co-CR discrepancy of 9 malocclusion groups. 4. There is very little, if any, correlation between Skeletofacial measurements and CO-CR discrepancy. 5. In the Class Ⅱ brachyfacial skeleton and ClassⅢ mesofacial skeleton there was Lateral cephalometric measurements by that we predict CPI measurements was detected. That was overbite, overjet, upper gonial angle, lower gonial angle, saddle angle, articular angle, convexity of point A, ANS-Me/Na-Me, PCBL/RH, Posterior FH/anterior FH.

Railroad station has changed the urban structure spatially, kept its role as a local point and been used as a means of urban development as the urban central axis. However, as the urban central axis has been shifted due to the external expansion of city and the spatial structure of city has been changed, it has caused a lot of urban problems such as housing difficulty and traffic jam at existing downtown. Therefore the transfer of Gwangju station is urgently required to settle many evils such as traffic jam, frequent traffic accidents, separation of life circle, noise and vibration due to the disconnection of traffic axis through the downtown. Accordingly, it will be desirable that Gwangju station will be transferred in consideration of conforming to balanced urban development of Gwangju city, urban spatial structure and residents convenience.

As for the travel demand analysis of the past, forcasting has been conducted by the use of revealed preference(RP) informations about actual or observed choice made by individuals. Forcasting method using RP data needs implict assumptions that there will be no remarkable change in existing transport conditions. However, in case of occuring the great change in existing conditions or adding a new choice-set of hypothetical options, it is very difficult to predict future travel demand. Fortunately in recent year, especially in the mode choice analysis, it has been preceived that the importance of individual performance data using ststed preference(SP) experiments as well as RP data. Since SP experiments present respondent with various hypothetical alternatives, which are produced by a combination of a number of different attribute levels, and ask them to indicate a preference, it is possible to analyze travel behavior under a situation of potential environment change such as proposed alternative mode of transportation. The basic problem, however, remains that SP are not consistent with the actual travel behaviors and the research reports has not been sufficiently from models estimated using SP data. Under this background, This study aims to analyze the factors affecting the mode choice behavior by the variance analysis of orthogonal-arrays-table, the transfer intention data and the mode choice model using SP data for the new subway system in Kwang-Ju For this analysis, we assumed subway operations in the Gwang-Ju, and set up a choice-set of hypothetical options based on Experimental Design Method.

Although, we could get more reasonable results from the transportation behavior study based on activity diary data, there were not make rapid progressing because of the absence of analytical methodology. Therefore, we set up causal structure model of activity participation, trip generation, and travel time by the structural equation modeling to conquer of the absence of analytical methodology. Results of our studies show that activity-diary can be analyzed by the structural equation modeling. It will be a good study momentum in the behavioral study based on activity diary which had not been generalized because of the absence of analytical methodology.

면역방사계수법을 이용한 Thyroglobulin 측정시 항 Thyroglobulin 항체의 존재가 미치는 영향

안병철,배진호,정신영,박호용,김정국,하승우,이재태,김보완,이규보 대한내분비학회 2004 Endocrinology and metabolism Vol.19 No.1

연구배경: 혈청 thyroglobulin (Tg)은 옥소전신스캔과 함께 분화갑상선암환자에서 갑상선암 재발에 대한 추적관찰에 매우 예민하고, 중요한 표지자로 임상에서 널리 이용된다. 그러나 많은 수의 분화갑상선암환자는 Tg 항체인 항 Tg 항체를 가지고 있고, 이는 방사면역검사법 (radioimmunoassay) 및 면역방사계수 검사법(immunoradiometric assay)으로 Tg 측정시 영향을 미칠 수 있다. 이에 연자들은 면역방사계수법으로 Tg를 측정할 경우, 항 Tg항체에 의하여 어떤 영향이 생길수 있는지를 알아보고자 하였다. 방법: 이중위치 고상법 (solid phase two-site)법을 이용하는 ELSA-hTg in vivo test (CIS international, Schering, France) 시약을 이용하여 Tg를 측정하였다. Tg과 항 Tg 항체는 검사시약에 포함된 표준용액을 사용하였으며, Tg는 두 가지 농도 (23.5 ng/mL, 62.5 ng/mL)로, 항 thyroglobulin 항체는 세 가지 농도(25U/mL, 50U/mL, 100U/mL)로 이용하였다. Tg가 높게 나타나는 환자의 혈청에 항 Tg 항체가 높게 나타나는 환자의 혈청을 혼합하여 동일한 방법으로 Tg 검사를 시행하였다. 통계학적 분석은 ANOVA와 Scheffe test 및 Quadratic regression modeling을 시행하였다. 결과: 면역방사계수법을 이용한 Tg 측정시 항 thyroglobulin 항체가 존재하는 경우 그 값이 낮게 측정되었다. Tg 농도가 23.5 ng/mL인 표준용액이 항 Tg 항체의 농도가 0, 25, 50 및 100U/mL 경우, 각각 24.5±1.1, 11.8±0.4, 7.7±0.1 및 4.5±0.4ng/mL로 측정되었으며, Tg 농도가 62.5 ng/mL인 표준용액은 각각 65.9±5.7, 36.3±2.2, 23.7±0.7, 및 14.0±1.0 ng/mL로 측정되었다(ANOVA test, p=0.000). 항 Tg 항체에 의한 Tg 측정값의 저하 정도는 항 Tg 항체의 농도에 비례하는 것으로 나타났다 (Quadratic model regression, SigT=0.000). 결론: 분화갑상선암환자에서 항 Tg 항체의 존재는 면역방사계수법을 이용한 혈청 Tg 측정으로 갑상선암 재발을 파악하는데 방해하는 인자로 작용될 수 있으며, Tg 측정시 항 Tg 항체의 측정이 꼭 필요하며, 항 Tg 항체를 가진 분화갑상선암환자에서 Tg 수치를 해석할 경우 세심한 주의가 요구된다. Background: Serum thyroglobulin (Tg) is a valuable and sensitive tool needed in the follow-up of patients with differentiated thyroid cancer (DTC), but antithyroglobulin antibody (Anti-Tg), common in patients with DTC, can interfere with the assay for Tg. In this study, we evaluated the influence of Anti-Tg on the measurement of Tg using the immunoradiometric assay (IRMA). Methods: In using ELSA-hTg in vivo test (CIS international, Schering, France), a solid phase two-site IRMA was used to measure Tg (23.5 ng/mL, 62.5 ng/mL) under the absence or presence of three concentrations of Anti-Tg (25U/mL, 50U/mL, 100U/mL). We also performed Tg measurement using patients serum that was mixed with patients serum containing high Anti-Tg. ANOVA and Scheffe tests were performed to evaluate the effect of Anti-Tg on Tg IRMA, and an inverse regression was made to calculate the level of Tg from measured Tg and used Anti-Tg levels and also to assess the degree of effect of anti-Tg on Tg IRMA. Results: In measuring Tg using the standard solution, the presence of Anti-Tg resulted in a falsely suppressed Tg value. The IRMAs for 23.5ng/mL of the standard Tg solution resulted in 24.5±1.1 ng/mL under no Anti-Tg, 11.8±0.4 ng/mL under 25U/mL of Anti-Tg, 7.7±0.1 ng/mL under 50U/mL of Anti-Tg, and 4.5±0.4 ng/mL under 100U/mL of Anti-Tg. IRMAs 62.5 ng/mL of the standard Tg solution resulted in 65.9±5.7 ng/mL under no Anti-Tg, 36.3±2.2 ng/mL under 25U/mL of Anti-Tg, 23.7±0.7 ng/mL under 50U/mL of Anti-Tg, and 14.0±1.0 ng/mL under 100U/mL of Anti-Tg. (ANOVA test, p=0.000). The degree of suppression of the measured Tg value was positively correlated with the Anti-Tg level (Quadratic model regression, Sig T=0.000). The presence of Anti-Tg also resulted in a falsely suppressed Tg value for the Tg measurement using patient's serum. 2004). Conclusion: The presence of Anti-Tg could consist of the use of Tg as a tumor, therefore Anti-Tg should be measured in all patients diagnosed with DTC. The interpretation of the Tg level must be performed with extreme caution in patients with Anti-Tg (J Kor Soc Endocrinol 19:42∼47, 2004)

참치 뼈에서 추출한 hydroxyapatite를 출발물질로 여러 가지 세라믹 복합체를 제조하여 인공체액에서의 hydroxyapatite 복합체간의 화학결합을 조사하였다. hydroxyapatite 복합체들은 인공체액에서 4주 후부터 화학 결합성질을 나타내었다. 결합강도는 bioglass가 가장 강하게 나타났으며, 조성에 따른 의존성은 관찰할 수 없었다. 인공체액에서 복합체들은 이들의 경계면에서 불균일 핵생성 및 성장에 의해 화학적 결합으로 이루어졌다. Chemical bonding was investigated in the simulated body fluid of several selected hydroxyapatite-containing composites. The hydroxyapatite-containing composites chemically bonded with each other in the simulated body fluid after 4 weeks. Bioglass was strongly bonded in the simulated body fluid, but bonding strength was not depended on composition. Their composite bodies were chemically bonded by heterogeneous nucleation and growth at the interfaces of the specimens in the simulated body fluid.

This study was conducted to analyze the tendency of obesity by subjective evaluation method in measuring the skinfold thickness in adolescents. The validity norms were height, weight, the sum of skinfold thickness, Db1, %Fat1, %Fat2, and BMI. The subjects surveyed were 2,442 boy and girl students of middle and high school in medium and small city and big city. The results are summarized as follows; 1. Weight of adolescents evaluated as obesity was over 76㎏ in boy's middle, over 67㎏ in gril's middle school, over 79㎏ in boy's high school, and over 68㎏ in girl's high school, the sum of skinfold thickness was over 40㎜, over 39㎜, over 54㎜, and over 41㎜ respectively. 2. Except the case of height in girl's middle, boy's high and girl's high school, in height in boy's middle, weight, the skinfold thickness, Db1, %Fat1, %Fat2, and BMI, difference among the degree of obesity evaluated subjectively was significant(p<.05). 3. Except heigh in girl's middle, boy's and girl's high school, correlation between the degree of obesity evaluated subjectively and height in girl's middle school, weight, the sum of skinfold thickness, Db1, %Fat1, %Fat2, BMI respectively was high and significant(p<.01 or p<.001) Therefore, on the basis of above results, I think we can evaluate the tendency of obesity in adolescents validly by subjective evaluation method as well.
