  • The author has studied the effect of clothes design to mask the dorsal curvature that is one of the commonest changes in elderly women. Body measurements including the body type and the status of dorsal curvature were perfor-med on 153 women of over 60 years of age, and then a body form to fit to the mean measure-ments was made to evaluate the effects of various designs to it. With 31 pattern designs modified by changing in their slash lines and gathers using darts, the diminishing effect of the rounded back were evaluated by means of sensory test. The results of this study can be summarized as follows: I . Results from the body measurements 1) The mean body type in elderly women was that of obesity. 2) With the advancement of age, the angle to indicate the degree of dorsal curvature as well as the angle to indicate the posture are increased. II . Concerning to the clothes design to diminish the shape of dorsal curvature 1) Among the designs by the position of darts, the basic pattern (Fig. 5-1-(1)) showed the best effect to mask the shape of dorsal curvature. 2) Out of the applied designs of princess lines, that in which the slash line is pointing toward the shoulder point (Fig. 5-2-(1)) seemed to be most effective. 3) What has angled princess line (Fig. 5-3-(1)) had the most diminishing effect among the waist darts and armhole princess lines. 4) Among the V-shaped designs, the slashed at the shoulder point (Fig. 5-4-(1)) had the best effect to lessen the shape of the dorsal cuuature. 5) Wider angle yoke had better effect to the narrow angle one among the designs with straight yoke, and that with downward direction (Fig. 5-5-(1)) showed the best effect. 6) Between straight wide angle yoke and curved yoke, that of curved one with downward direction (Fig. 5-6-(1)) had better effect as far as the masking effect of dorsal curvature is concerned. 7) Gathers around the neck showed better effect to those around the shoulder, and the more amount of gathers (Fig. 5-7-(1)), there was better effect. 8) The design with midline gathers at the level of horizontal slash line of armhole (Fig. 5-8-(1)) showed better effect to that with seperated gathers. 9) In case of design with gathers at the horizontal line of armhole, it showed the better effect with less amount of gathers in midline ones, but with more amount in the side ones. 10) Considering all 7 different designs with better effect in covering the shape of dorsal curvature, it was evident that the design with gathers was far better than the design with application of slash lines.

  • Purpose - Recently, although corporate social responsibility activities have been increasing in size, they do not have to achieve qualitative improvements and can be passive and cost consuming. Therefore, companies should make quantitative as well as qualitative improvements in their efforts in corporate social responsibility activities. In this study, the classification of social responsibility activities in a variety of studies was analyzed through a more specific path than in previous studies. Corporate behavior image, social behavior image, and corporate contributions image were analyzed through a more detailed analysis of performance. This study suggests that more detailed and concentrated social responsibility activities be pursued by forming companies. Research design, data, and methodology - The purpose of study is to gauge the corporate need for a more intensive, specific area of CSR activities. For this purpose, the sample of consumers that were targeted for CSR activities, recognized as 261 persons, have been investigated. Through a theoretical discussion on previous research, nine hypotheses were established on corporate image, the influence of corporate performance on CSR, and the CSV regulation effect. In order to test the hypothesis, a survey was conducted on 261 male and female consumers who were targeted for CSR, being persons in their 20s to 40s. PASW Statistics 18.0 and AMOS 18.0 were used for statistical analysis. Results - Corporate behavior image was formed through legal responsibility activities and economic responsibility activities. In addition to economic responsibilities, ethical responsibilities and environmental responsibilities were confirmed to have influence on social behavior image. Corporate social responsibility and philanthropic responsibility were confirmed to have influence on economic contribution image. Corporate image has positive effects on brand attitude, corporate reputation, and corporate competition. In addition, when CSV awareness is high, consumers perceive corporate image only through economic responsibility. However, when CSV awareness is low, economic responsibility as well as legal responsibility through charitable activities form the corporate image that influences the brand attitude and corporate reputation, as well as corporate competitiveness. It would appear that the area of corporate social responsibility needs more intensive management for corporate image and corporate competitive advantage. Conclusion - First, the findings of this study show that each CSR activity has a different effect on corporate image and thus, the corporate image influences corporate performance in distinct ways, depending on the CSR activity. This implies that reactive strategies should be tailored to the required image. Second, there is a difference in CSV awareness between groups. When the CSV awareness is low, we can confirm that legal responsibility activities have an especially significant effect on corporate image, implying that corporations should pursue their economic objectives within legal regulations and need to invest significant time and effort for this. This study has limited generalization potential because the result of the model fit has insufficient reference value. In future research, we need to approach various dimensions of corporate performance.

  • 불의의 방사선 피폭 환자의 체내 방사선 피폭선량의 예측을 위한 방사선 생물학적 선량측정 개발의 일환으로 저선량 피폭환자의 체내 피폭선량 측정 지표로서의 미소핵 분석법 이용 가능성을 평가하기 위하여 코발트-60 감마선을 0.25 Gy에서 1 G의 선량을 인체 말초 혈액에 조사한 후 임파구내에 미소핵의 수적 변화를 형태학적으로 관찰하였다. 저선량에 피폭된 임파구에서 미소핵이 관찰되었으며, 선량에 따른 수적인 변화도 나타났다. 저선량 피폭에 대한 미소핵의 수적 변화에 대한 선량-반응 곡선은 $Y=(0.02{\pm}0.0009)+(0.033{\pm}0.010)D+(0.012{\pm}0.012)D^2$의 식을 얻었으며, linear quadratic model 이였다. 이상의 결과에서 미소핵의 발생 빈도와 피폭 선량간에 유의한 효과가 있는 것으로 확인되었다. 그리고 정상대조군에서는 세포당 $0.02{\pm}0.0009$개가 관찰되었다. 따라서 말초 임파구를 이용한 미소핵 분석법은 저선량 피폭환자의 체내 피폭선량 측정은 물론 방사선 방호제의 검색 및 방사선 민감도 검사를 위한 방사선 생물학적 지표로 이용 가능하며, 특히 이 방법은 간편하고 정확하며 재현성이 있는 방법으로 불의의 방사선 피폭 사고시 체내 피폭선량을 예측하는 좋은 지표로 사용되어질 수 있을 것으로 사료됨.

  • 국내 시판되는 각 제분사별 면용밀가루(n=8) 중에서 중력밀가루(AF, n=4)와 고급면용밀가루(PF, n=4)를 일반성분분석과 입도, 반죽특성, Texture analyzer, 관능검사를 통하여 비교하였다. 조단백질함량은 AF, PF가 각각 평균 8.97~9.26%, 8.53~9.06%로 나타났고, 조회분함량은 AF, PF가 각각 0.38~0.40%, 0.35~0.39%로 PF가 단백질함량, 0.20~0.45%, 회분함량, 0.01~0.03%가 AF보다 낮은 결과였다. 국내에서 면용에 주로 이용되는 밀가루의 입도는 $47.5{\sim}56.5{\mu}m$의 범위임을 알 수 있었다. Farinogram의 흡수율은 AF가 57.08~59.70%, PF는 58.00~61.50%의 결과를 보여 PF가 1~2% 높은 흡수율임을 나타냈다. 형성시간은 AF가 1분20초~2분, PF는 5분-8분의 결과로 PF가 약 3분40초~6분 긴 형성시간의 특성을 보였다. 최고점도는 AF가 660~839 BU, PF는 667~983 BU의 범위를 보였다. Texture analyzer 측정값의 견고도, 부착성, 검성 모두 밀가루 종류별 차이보다는 제분사별 차이를 보여 제조공정 조건의 차이에 따른 영향으로 판단할 수 있었다. 관능검사 결과 부드러운 정도와 기호도는 PF가 AF보다 좋게 평가되었다. 상관관계의 결과와 같이 회분함량이 낮을수록, 입도가 작을수록, 반죽형성시간이 길수록, 강력도가 높고, 약화도가 작을수록, 부드러움이 좋았으며, 기호도가 높음을 알 수 있었다. 이와 같은 결과에 따라 회분함량이 높은 AF(중력밀가루)보다 회분함량이 낮으며 입도가 작은 PF(고급면용밀가루)가 생면용에 우수하다는 결과를 얻을 수 있었다.

  • Most hydro]ogic phenomena are the complex and organic products of multiple causations like climatic and hydro-geological factors. A certain significant correlation on the run-off in river basin would be expected and foreseen in advance, and the effect of each these causual and associated factors (independant variables; present-month rainfall, previous-month run-off, evapotranspiration and relative humidity etc.) upon present-month run-off(dependent variable) may be determined by multiple regression analysis. Functions between independant and dependant variables should be treated repeatedly until satisfactory and optimal combination of independant variables can be obtained. Reliability of the estimated function should be tested according to the result of statistical criterion such as analysis of variance, coefficient of determination and significance-test of regression coefficients before first estimated multiple regression model in historical sequence is determined. But some error between observed and estimated run-off is still there. The error arises because the model used is an inadequate description of the system and because the data constituting the record represent only a sample from a population of monthly discharge observation, so that estimates of model parameter will be subject to sampling errors. Since this error which is a deviation from multiple regression plane cannot be explained by first estimated multiple regression equation, it can be considered as a random error governed by law of chance in nature. This unexplained variance by multiple regression equation can be solved by stochastic approach, that is, random error can be stochastically simulated by multiplying random normal variate to standard error of estimate. Finally hybrid model on estimation of monthly run-off in nonhistorical sequence can be determined by combining the determistic component of multiple regression equation and the stochastic component of random errors. Monthly run-off in Naju station in Yong-San river basin is estimated by multiple regression model and hybrid model. And some comparisons between observed and estimated run-off and between multiple regression model and already-existing estimation methods such as Gajiyama formula, tank model and Thomas-Fiering model are done. The results are as follows. (1) The optimal function to estimate monthly run-off in historical sequence is multiple linear regression equation in overall-month unit, that is; Qn=0.788Pn+0.130Qn-1-0.273En-0.1 About 85% of total variance of monthly runoff can be explained by multiple linear regression equation and its coefficient of determination (R2) is 0.843. This means we can estimate monthly runoff in historical sequence highly significantly with short data of observation by above mentioned equation. (2) The optimal function to estimate monthly runoff in nonhistorical sequence is hybrid model combined with multiple linear regression equation in overall-month unit and stochastic component, that is; Qn=0. 788Pn+0. l30Qn-1-0. 273En-0. 10+Sy.t The rest 15% of unexplained variance of monthly runoff can be explained by addition of stochastic process and a bit more reliable results of statistical characteristics of monthly runoff in non-historical sequence are derived. This estimated monthly runoff in non-historical sequence shows up the extraordinary value (maximum, minimum value) which is not appeared in the observed runoff as a random component. (3) "Frequency best fit coefficient" (R2f) of multiple linear regression equation is 0.847 which is the same value as Gaijyama's one. This implies that multiple linear regression equation and Gajiyama formula are theoretically rather reasonable functions.

  • State of problem: Zirconia all-ceramic restoration fabricated with CAM system is on an increasing trend in dentistry. However, evaluation of the marginal and internal fits of zirconia bridge seldomly have been reported. Purpose: This study was to evaluate the at of margin and internal surface in posterior 3-unit zirconia bridge framework fabricated with CAM system(DeguDent, Germany). Material and Method: Preparations of secondary premolar and secondary molar on artificial resin model were performed for fabrication of 3-unit posterior bridge framework. Fits of 5 zirconia bridge framework were compared with 5 precious ceramo-metal alloy framework(V-GnathosPlus, Metalor, Switzerland), and prepared margins were designed to chamfer and shoulder finishing line. Each framework was cemented to epoxy resin model with reinforced glass ionomer(FujiCEM, GC Co., Japan), embedded in acrylic resin and sectioned in two planes, mesio-distal and buccolingual. Samples were divided into six pieces by sectioning and had two pieces of each surface(i.e mesial, distal, buccal and lingual surface) per abutment, so there were eight measuring points in each abutment. External gap was measured at the margin and internal gaps were measured at the margin, axial and occlusal surface. Gaps were observed under the measuring microscope(Compact measuring microscope STM5; Olympus, Japan) at a magnification of $\times100$. T-test were used to determine the statistic significance of the different gaps between zirconia and metal framework. Results and Conclusion: 1. External and internal marginal gaps of zirconia and metal framework were in clinically acceptable range. External marginal gaps were not different significantly between zirconia$(81.9{\mu}m)$ and metal $(81.3{\mu}m)$ framework and internal marginal gaps of zirconia $(44.6{\mu}m)$ were smaller than those of metal framework $(58.6{\mu}m)$. 2. Internal axial gaps of zirconia framework$(96.7{\mu}m)$ were larger than those of metal frame-work$(78.1{\mu}m)$ significantly and adversely, internal occlusal gaps of zirconia frame-work$(89.4{\mu}m)$ were smaller than those of metal framework $(104.9{\mu}m)$ significantly. 3. There were no significant differences in external and internal marginal gaps between chamfer and shoulder finish line when zirconia frameworks were fabricated.

  • 연구 목적: 합금의 종류와 지대주의 재질의 차이가 변연적합도에 미치는 영향을 비교 분석하고자 한다. 연구 재료 및 방법: 2개의 임플란트 유사체를 평행하게 위치시킨 후 아크릴릭 레진으로 포매하여 연구모형을 제작하였다. 바 구조물은 gold UCLA 지대주에 고귀금속 합금(high noble metal alloy)과 귀금속 합금(noble metal alloy)을, 그리고 metal UCLA 지대주에 고귀금속 합금과 비귀금속 합금(base metal alloy)을 이용하여 총 4 종류의 바 구조물을 7개씩 시편을 제작하였다. 주조된 바 구조물을 레진 모형에 장착하고 한쪽 지대나사를 조인 후, 반대쪽 임플란트-지대주 간극의 수직 거리를 앞, 뒤, 측면 3부위에서 입체 광학 현미경으로 관찰하여 기록하였다. 결과: 각 군들의 변연오차 평균값은 gold UCLA 지대주에 고귀금속 합금과 귀금속 합금을 사용했을 때 각각 $13.69{\pm}6.74{\mu}m$$267.26{\pm}65.85{\mu}m$이었으며, metal UCLA 지대주에 고귀금속 합금과 비귀금속 합금을 사용했을 때 $26.19{\pm}8.14{\mu}m$$61.90{\pm}33.65{\mu}m$이었다. One-way ANOVA를 이용하여 변연 적합도의 차이를 분석했을 때 고귀금속 함금을 사용한 군들을 제외하고, 모든 군간에 유의한 차이가 존재하였다($P$<.05). Gold UCLA 지대주-귀금속 합금 조합을 제외하고 모두 $70{\mu}m$ 이하의 수직오차를 보였다. 결론: 임플란트 바 유지 장치의 제작에 있어서 고귀금속 합금 대신 비귀금속 합금과 metal UCLA 지대주를 사용하는 것은 임상적 타당성이 있다고 판단된다.

  • 일반적으로 정신장애에 대한 반낙인 프로그램들은 '정신장애가 다른 신체질환과 마찬가지로 생물학적 장애'임을 강조한다. 이는 귀인정서이론에 근거한 것이다. 그러나 본 연구는 선행연구들을 바탕으로 정신장애 원인을 생물학적 원인과 같은 통제 불가능한 것으로 귀인 하는 경우, 통제 가능한 것으로 귀인하는 경우와 마찬가지로 분노와 두려움이라는 정서를 매개로 사회적 거리감을 증가시킬 것이라는 수정된 귀인정서 모형을 제안하였다. 모형의 적합도를 높이기 위해 모형수정 작업을 통해 최종 수정된 귀인정서모형을 선택하였다. 최종모형의 경로를 분석한 결과 모든 경로는 통계적으로 유의하여 정신장애의 원인을 통제 가능한 것으로 보는 경우와 통제 불가능한 것으로 보는 경우 모두 두려움과 분노를 매개로 사회적 거리감을 증가시키는 것으로 나타났다. 이러한 모형이 정신분열, 알코올중독, 우울증 사례에 동일하게 적용되는지를 알아보기 위해 다집단분석을 실시한 결과 세 집단 모두에 동일하게 적용된다는 전제가 적합한 것으로 나타났고 경로계수의 강도와 크기 역시 유사하게 적용되는 것으로 나타났다. 그러나 전체 모형과 달리 정신장애를 통제 가능한 것으로 인식하는 경우 두려움을 매개로 사회적 거리감을 증가시키는 경로는 통계적으로 유의하지 않았다. 따라서 통제 가능한 원인으로 보는 경우 분노를 매개로 사회적 거리감을 증가시키지만 통제 불가능한 원인으로 보는 경우 두려움을 매개로 사회적 거리감을 증가시키는 것을 알 수 있다. 이를 바탕으로 연구자들은 의료적 모델로 대중을 교육하는 편견극복방법에 수정이 필요함을 지적하였다.

  • Objective: The objective of this study was to evaluate increasing doses of a novel microbial phytase (Cibenza Phytaverse, Novus International, St. Charles, MO, USA) on standardized total tract digestibility (STTD) of P in canola meal (CM), corn, corn-derived distiller's dried grains with solubles (DDGS), rice bran (RB), sorghum, soybean meal (SBM), sunflower meal (SFM), and wheat. Methods: Two cohorts of 36 pigs each (initial body weight = $78.5{\pm}3.7kg$) were randomly assigned to 2 rooms, each housing 36 pigs, and then allotted to 6 diets with 6 replicates per diet in a randomized complete block design. Test ingredient was the only dietary source of P and diets contained 6 concentrations of phytase (0, 125, 250, 500, 1,000, or 2,000 phytase units [FTU]/kg) with 0.4% of $TiO_2$ as a digestibility marker. Feeding schedule for each ingredient was 5 d acclimation, 5 d fecal collection, and 4 d washout. The STTD of P increased (linear or exponential $p{\leq}0.001$) with the inclusion of phytase for all ingredients. Results: Basal STTD of P was 37.6% for CM, 37.6% for corn, 68.6% for DDGS, 10.3% for RB, 41.2% for sorghum, 36.7% for SBM, 26.2% for SFM, and 55.1% for wheat. The efficiency of this novel phytase to hydrolyze phytate is best described with a broken-line model for corn, an exponential model for CM, RB, SBM, SFM, and wheat, and a linear model for DDGS and sorghum. Based on best-fit model the phytase dose (FTU/kg) needed for highest STTD of P (%), respectively, was 735 for 64.3% in CM, 550 for 69.4% in corn, 160 for 55.5% in SBM, 1,219 for 57.8% in SFM, and 881 for 64.0% in wheat, whereas a maximum response was not obtained for sorghum, DDGS and RB within the evaluated phytase range of 0 to 2,000 FTU/kg. These differences in the phytase concentration needed to maximize the STTD of P clearly indicate that the enzyme does not have the same hydrolysis efficiency among the evaluated ingredients. Conclusion: Variations in enzyme efficacy to release P from phytate in various feedstuffs need to be taken into consideration when determining the matrix value for phytase in a mixed diet, which likely depends on the type and inclusion concentration of ingredients used in mixed diets for pigs. The use of a fixed P matrix value across different diet types for a given phytase concentration is discouraged as it may result in inaccurate diet formulation.
