The objective of this study was to analyze patient satisfaction and perception of nutritional counseling services quality. A patient satisfaction and perception survey was conducted for 1,095 patients from 43 tertiary hospitals and 20 general hospitals. The number of returned questionnaires was 656 (response rate: 60.0%). Data from 633 questionnaires were analyzed after the questionnaires with unanswered items were excluded. Five domains were identified from the result of the factor analysis using the maximum likelihood and oblique rotation. The five domains were named empathy, responsiveness, tangibles, reliability, and skill and specialty. Patient perception mean score of nutritional counseling was 4.54/5.00. Patient satisfaction scores were significantly higher in empathy (P<0.001), responsiveness, and skill and specialty (P<0.01) with a college or graduate school education than in patients with a middle school education. There was no statistically significant difference between satisfaction scores in tertiary hospitals and those in general hospitals, but patients in capital hospitals reported significantly higher scores than their local counterparts in empathy, responsiveness, reliability, skill and specialty (P<0.001), and tangibles (P<0.05). In responsiveness, significantly higher (P<0.01) scores were observed in patients who received nutritional counseling only once compared to patients who received counseling two times. Patients perception of nutritional counseling services was significantly correlated with their satisfaction of five domains, reliability (r=0.721), responsiveness (r=0.697), empathy (r=0.690), skill and specialty (r=0.678), and tangibles (r=0.622).

현대의 건축시기는 다원성의 시기 또는 복합성의 시기라고 불리운다. 모더니즘과 포스트모더니즘의 시기를 거치며 다양한 형태적 실험의 과정을 겪었고 수많은 이데올로기와 이론들로 무장된 논쟁의 역사도 갖게 되었다. 이러한 현대건축의 다양성은 건축디자인이라는 전문직의 사회에 기여하는 역할을 반추(反芻)함과 동시에 다변하는 인간사고의 역동성을 반영하고 있다. 건축관련 책자나 저널 등에서 흔히 발견할 수 있는 Neo-Classicism, Deconstructivism, Minimalism, High-Tech, New Moderns 등등의 건축양식들은 스타일을 지칭하는 언어라기보다는 건축적 사고를 지칭하는 언어라고 할 수 있다. 결국 건축디자인이라는 작업은 인간을 둘러 싼 건조환경의 생성에서 출발하는 것이므로 건축적 사고방식은 그 시기의 사회현상과 밀접한 관계를 맺게 된다. 20세기 말부터 불어닥친 디지털 문화의 사회변혁은 전 세계를 하나의 채널로 엮게 되었고, 이러한 영향들은 지역과 민족, 그리고 종교적인 요소들까지도 혼합하여 국경을 초월한 미래의 새로운 이상들을 꿈꾸게 되었다. 19세기 산업혁명과 함께 급속히 벨라진 인류문명의 진보는 필수적으로 세계화를 동반하는 것이고, 세계화와 지역성사이의 괴리를 통해 나타나는 문화적 비판과 충돌은 아직도 진행상태인 것이다. 세계화라는 통염은 문명의 보편성을 기반으로 하며 전통문화의 파괴가 뒤따를 수밖에 없는데, 현재와 같이 IT혁명을 통해 급속도로 빨라진 세계문화의 교류는 한 국가가 뿌리를 내리고 있는 문화적 유산이라는 토양을 포기하여야 할 단계에 와 있다고 논평할 정도이다. 여기서 건축은 문화적 상징으로 작용하게 되는데, 그것이 심미적이든 관습적이든 또는, 경제적이든 건축가는 해답의 제시라는 임무에 직면하게 된다. 20세기에 진행된 모더니즘의 건축은 구조와 공간에 대한 고전건축의 숙원을 고덕건축이 이룬 것처럼 15세기 르네상스 시대로부터 진행된 형태와 공간, 기능, 그리고 아름다움과 기술(technology) 또는 경제성 등에 대한 건축적 의문과 탐구를 일단락지었다고 할 수 있다. 이러한 모더니즘의 한복판에 Mies van der Rohe라는 거장이 깊은 발자국을 남기며 한 시대를 이루었고 그가 남긴 시대정신의 이념과 가치를 Miesianism이라고 부른다. 실용성과 도덕성을 근본으로 하는 Miesianism은 대중에 호소하는 미적 표현주의를 부정하고 지역정서를 중시하는 문맥적 접근방식을 경시함으로써 보편화라는 현상을 불러일으킨 국제주의 양식의 한 부류로 비판을 받아왔다. 즉, Miesianism의 단순하고 강렬한 외형적 요소는 그것이 내포하는 기술적 합리성이나 공간적 완결성을 무시한 채 전 세계에 영향을 미쳤고 동시에 지역적 저항을 받게 되었다. 시카고 및 전 세계의 Miesian들, 즉 Mies van der Rohe의 제자들이나 그로부터 영향을 받은 수많은 건축가들은 이러한 저항과 비판에 직면하게 되며 새로운 사고의 시대적 요구 앞에 고뇌하게 된다. 한국에서는 1978년 Mies van der Rohe의 제자인 김종성이 미국에서 서울로 돌아와 '서울건축컨설탄트'를 설립하며 본격적으로 Miesianism의 규범적 건축론을 설파하기 시작하였다. 이른바 시카고 국제주의학파의 건축전수라고 할 수 있는데 '서울건축컨설탄트'를 통하여 배출된 김종성의 제자들은 명쾌하고도 간결한 건축해법의 경험을 토대름대로의 정체성을 갖고자 노력하였으나 결국 다원적 가치를 요구하는 시대적 흐름 속에 혼란을 겪고 있는 것 또한 사실이다. 본 연구는 Miesianism의 기원을 밝히고 그것의 실수와 오류를 밝힘과 동시에 현대의 여러 가지 건축유형들과 비교하여 봄으로써 Post-Miesianism의 실체와 그 미래에 대하여 고찰하여 보고자 한다. 미스의 유산이라고 할 수 있는 Miesianism의 요체는 첫째, Schinkel로부터 이어받은 시대정신의 사명감, 둘째, Berlage가 전해준 전문가로서의 도덕성을 바탕으로 하여 이루어진 기술적 합리성의 실현, 그리고 마지막으로 그 당시의 추상예술에 대한 이해로써 받아들인 nee-Suprematism의 아방 가르데적인 자세라고 할 수 있다. 그러나 이것들을 전파하고 수용하는 과정에서 미스적인 단순하고 명쾌한 외관이 더욱 강한 인상을 남기게 되었고 또한 미스가 현대성의 본질이라고 믿는 기술의 전수는 모든 외관을 동일하게 만드는 International Style로서의 보편적 획일성을 초래하였다. Mies van der Rohe의 강력하고 규범적인 dogma는 그의 제자들에게는 강렬한 카리스마로 각인되었고, Mies가 원한 것이 아닐지라도 그들을 하나의 틀 속에 가두는 영향력을 행사하였다. 2세대이든 3세대이든 기술적 합리성과 추상적 단순미라는 믿음을 맹목적으로 추종할 때 그들은 Miesian으로 남아있게 되며, 거기서 벗어났을 때 non-Miesian, 또는 배신자로 취급하기까지 하였다. 이것은 미스의 제자들에게 강한 족쇄가 되어 형태적 또는 개념적 변화의 시도를 어렵게 하였고 시대적 요구에 부응하지 못한다는 평가에 이르게 되었다. 문화의 다양성과 역동성을 인정함과 동시에 Miesianism에 대한 새롭고 시대에 적합한 해석을 기대하게 되는데, 이러한 기대 속에서 우리는 Post-Miesianism이라는 새로운 유형을 엿볼 수 있게 된다. Post-Miesianism의 징후를 현대의 다양한 건축유형에서 발견할 수 있는데, High-Tech의 구축적이고 정밀한 건축 기술적 해법과 Minimalism의 반복성을 통한 추상미의 표현 등에서 뿐만이 아니라 Post-Modernism의 인간성의 추구나 문맥적 고려, 또는 해체주의의 형이상학적이고 아방가르데적인 실험주의 정신까지조차 Post-Miesianism이 공유할 수 있는 부분이 있다고 보여진다. 또한, 미스의 영향이 2세대, 3세대의 건축가들에게 미치면서 여러 방향으로 변질되어 가는 것을 우리는 발견할 수 있으며 그러한 시대성에 적응하는 시도들이야말로 새로운 미래를 향한 Post-Miesianism의 실체인 것이다. Mies가 말하였듯이 한 시대의 끝은 그 시대가 완전히 이해되었을 때이며, 모더니즘의 숙제는 아직 해결되지 않았으므로 Miesianism의 탐구는 Post-Miesianism이라는 새로운 주제로 계속될 것이다. 이를 통하여 21세기 디지털 문명의 시대 속에서 현대건축이 안을 수밖에 없는 보편성과 지역성의 충돌이라는 문제의 해결에 한 발걸음 다가갈 수 있기를 기대하여 본다.

The joints in the jointed concrete pavement provide a control against transverse or longitudinal cracking at slab, which may be caused by temperature or moisture variation during or after hydration. Without control of cracking, random cracks cause more serious distresses and result in structural or functional failure of pavement system. However, joints nay cause distresses due to its inherent weakness in structural integrity. Thus, the evaluation at joint is very important. and the joint-related distresses should be evaluated reasonably for economic rehabilitation. The purpose of this paper was to develop an evaluation system at joints of jointed concrete pavement using finite element analysis program, ILLI-SLAB, and nondestructive testing device. FWD. To develop an evaluation system for JCP, a sensitivity analysis was performed using ILLI-SLAB program with a selected variables which might affect fairly to on the performance of transverse joints. The most significant variables were selected from precise analysis. An evaluation charts were made for jointed concrete pavement by adopting the field FWD data. It was concluded that the variables which most significantly affect to pavement deflections are the modulus of subgrade reaction(K) and the modulus of dowel/concrete interaction(G), and limiting criteria on the performance of joints at JCP are 300pci. 500,000 lb/in. respectively. Using these variables and FWD test, a charts of load transfer ratio versus surface deflection at joints were made in order to evaluate the performance of JCP. Practically, Chungbu highway was evaluated by these evaluation charts and FWD field data for jointed concrete pavement. For Chungbu highway, only one joint showed smaller value than limiting criterion of the modulus of dowel/concrete interaction(G). The rest joints showed larger values than limiting criteria of the modulus of subgrade reaction(K) and the modulus of dowel/concrete interaction(G).

Rock bridge in rock masses can be considered as one of several types of opening-mode fractures, and also it has been known to have a great influence on the stability of structures in rock mats. In the beginning of researching a rock bridge it used to be studied only in characteristics of its behavior, as considering resistance of material itself. However the distribution pattern of rock bridges, which can affect the stability of rock structures, is currently researched with a fracture mechanical approach in numerical studies. For investigating the effect of rock bridges on the development pattern of hydraulic fractures, the author analyzed numerically the stress state transition in rock bridges and their phenomena with a different pattern of the rock bridge distributons. From the numerical studies, a two-crack configuration could be defined to be representative of the most critical conditions for rock bridges, only when cracks are systematic and same in their length and angle. Moreover, coalescence stresses and onset of propagation stresses could be known to increase with decreasing s/L ratio or increasing d/L ratio. The effect of pre-existing crack on hydraulic fracturing was studied also in numerical models. Different to the simple hydraulic fracturing modeling in which the fractures propagated exactly parallel to the maximum remote stress, the hydraulic fractures with pre-existing cracks dial not propagate parallel to the maximum remote stress direction. These are representative of the tendency to change the hydraulic fractures direction because of the existence of pre-existing crack. Therefore s/L, d/L ratios will be identical as a function effective on hydraulic fractures propagation, that is, the $K_{I}$ vague increase with decreasing s/L ratio or increasing d/L ratio and its magnification from onset to propagation increases with decreasing s/L ratio. The scanline is a commonly used method to estimate the fracture distribution on outcrops. The data obtained from the scanline method can be applied to the evaluation of stress field in rock mass.s.

To improve the performance of estimation, the research that uses additional information addition to traffic count and target OD with additional survey cost have been studied. The purpose of this paper is to improve the performance of OD estimation by reducing the feasible solutions with cost-efficiently additional information addition to traffic counts and target OD. For this purpose, we Propose the OD estimation method with sample link use proportion as additional information. That is, we obtain the relationship between OD trip and link flow from sample link use proportion that is high reliable information with roadside survey, not from the traffic assignment of target OD. Therefore, this paper proposes OD estimation algorithm in which the conservation of link flow rule under the path-based non-equilibrium traffic assignment concept. Numerical result with test network shows that it is possible to improve the performance of OD estimation where the precision of additional data is low, since sample link use Proportion represented the information showing the relationship between OD trip and link flow. And this method shows the robust performance of estimation where traffic count or OD trip be changed, since this method did not largely affected by the error of target OD and the one of traffic count. In addition to, we also propose that we must set the level of data precision by considering the level of other information precision, because "precision problem between information" is generated when we use additional information like sample link use proportion etc. And we Propose that the method using traffic count as basic information must obtain the link flow to certain level in order to high the applicability of additional information. Finally, we propose that additional information on link have a optimal counting location problem. Expecially by Precision of information side it is possible that optimal survey location problem of sample link use proportion have a much impact on the performance of OD estimation rather than optimal counting location problem of link flow.

In Korea, there have been various methods of estimating groundwater recharge which generally can be subdivided into three types: baseflow separation method by means of groundwater recession curve, water budget analysis based on lumped conceptual model in watershed, and water table fluctuation method (WTF) by using the data from groundwater monitoring wells. However, groundwater recharge rate shows the spatial-temporal variability due to climatic condition, land use and hydrogeological heterogeneity, so these methods have various limits to deal with these characteristics. To overcome these limitations, we present a new method of estimating recharge based on water balance components from the SWAT-MODFLOW which is an integrated surface-ground water model. Groundwater levels in the interest area close to the stream have dynamics similar to stream flow, whereas levels further upslope respond to precipitation with a delay. As these behaviours are related to the physical process of recharge, it is needed to account for the time delay in aquifer recharge once the water exits the soil profile to represent these features. In SWAT, a single linear reservoir storage module with an exponential decay weighting function is used to compute the recharge from soil to aquifer on a given day. However, this module has some limitations expressing recharge variation when the delay time is too long and transient recharge trend does not match to the groundwater table time series, the multi-reservoir storage routing module which represents more realistic time delay through vadose zone is newly suggested in this study. In this module, the parameter related to the delay time should be optimized by checking the correlation between simulated recharge and observed groundwater levels. The final step of this procedure is to compare simulated groundwater table with observed one as well as to compare simulated watershed runoff with observed one. This method is applied to Mihocheon watershed in Korea for the purpose of testing the procedure of proper estimation of spatio-temporal groundwater recharge distribution. As the newly suggested method of estimating recharge has the advantages of effectiveness of watershed model as well as the accuracy of WTF method, the estimated daily recharge rate would be an advanced quantity reflecting the heterogeneity of hydrogeology, climatic condition, land use as well as physical behaviour of water in soil layers and aquifers.

Background: A retrospective study was conducted to analyze the results of St. Jude Medical mitral valve replacement at the Chonbuk National University Hospital since the initial implant in May 1984. Material and Method: Between May of 1984 and December of 1996, 95 patients underwent MVR with the St. Jude Medical mechanical valve prosthesis at Department of Medical Science of Chonbuk National University Hospital and follow-up ended in May of 2004. Result: Age ranged from 19 to 69 years. Follow-up (mean${\pm}$standard deviation) averaged $10.6{\pm}4.2\;year$. Thirty-day operative mortality was 4.2% (4/95). Nine late deaths have occurred and actuarial survival was $90.5{\pm}3.0%,\;87.9{\pm}3.4%\;and\;83.2{\pm}4.6%$ at 5, 10 and 20 years, respectively. Probability of freedom from valve-rotated death was $95.5{\pm}2.1%,\;94.3{\pm}2.4%\;and\;91.0{\pm}3.9%$ at 5, 10 and 20 years, respectively. Seven patients have sustained thromboembolic events (1,05%/patient-year). Fifteen patients had anticoagulation related hemorrhage (3.56%/patient-year). There was no structural valve deterioration. Probability of freedom from all complications was $82.0{\pm}3.9%,\;71.3{\pm}4.8%\;and\;42.4{\pm}10.5%$ at 5, 10 and 20 years, respectively. Conclusion: We confirm the effective and excellent durability of the St. Jude Medical prosthesis in the mitral position with a low event rate at long-term follow-up. It also demonstrates the commonly encountered practical difficulty of adjusting the anti-coagulation protocol in patients with prosthetic mitral valves.
