1997년도 우리나라 굴 총생산량은 약 20만여톤으로 일반 패류 생산량의 절반 이상을 차지하고 있으며, 대부분이 양식에 의존하고 있다. 양식산굴은 대략11월부터 출하하기 시작하여 3월까지는 주로 생식용으로, 산란기로 접어드는 4월부터 6월까지는 주로 통조림용으로 이용되고 있다. 통조림의 제조를 위한 원료 굴은 델 등의 제거를 목적으로 수세하고, 레토르트에서 자숙 및 탈각한 후 이물질 등을 제거하기 위하여 탈각 굴에 대하여 수세 및 탈수와 같은 전처리 공정을 거치게 된다. (중략)

본 논문에서는 다수 객체 모델을 통해 잘못된 객체 모델 갱신의 영향을 줄이고 객체 추적의 정확도를 향상시키기 위한 방법을 제안한다. 객체 모델 집합은 다수의 객체 모델과 대응하는 가중치들로 정의된다. 각 델과의 유사도 가중 합을 고려 하여 객체 위치를 추정하고, 각 모델의 추정 신뢰도를 계산하여 가중치를 갱신한다. 실험 결과를 통해 제안하는 기법이 오클루젼, 밝기 변화로 인하여 객체 외형이 왜곡되었을 때 추적 성능을 크게 개선함을 보이고 기존 기법들보다 더 정확한 추적 결과를 제공함을 확인한다.

In recent years, the increase of secondary controls within vehicles requires a mechanism to integrate various controls into a single device. This paper presents control performance of an integrated magnetorheological (MR) haptic device which can adjust various in-vehicle comfort instruments. As a first step, the MR fluid-based haptic device capable of both rotary and push motions within a single device is devised as an integrated multi-functional instrument control device. Under consideration of the torque and force model of the proposed device, a magnetic circuit is designed. The proposed MR haptic device is then manufactured and its field-dependent torque and force are experimentally evaluated. Furthermore, an inverse model compensator is synthesized under basis of the Bingham model of the MR fluid and torque/force model of the device. Subsequently, haptic force-feedback maps considering in-vehicle comfort functions are constructed and interacts with the compensator to achieve a desired force-feedback. Control performances such as reflection force are experimentally evaluated for two specific comfort functions.

The Gallery of Casa del Agua in Jeju Island was demolished by Jeju local government on March 6 in the last year. In the meanwhile, a lot of people including the architectural field had denied the demolition. Regardless of sustained efforts in order that the building could be preserved as a work, Jeju government ended up with demolishing the gallery. The Gallery of Casa del Agua was a temporary building constructed as a model house of Casa del Agua. As the remaining period of the temporary building had passed, it was on the verge of demolition by Jeju government. Casa del Agua is 'dwelling of water' in Korean, and the building was the last posthumous work of Mexican architect Ricardo Legorreta. Knowing from the expression of 'dwelling of water', this house is a dwelling work of him. Through this work, his architecture languages that he had pursued contained in dwelling could be looked into. This study examined the background and course of demolition of the Gallery of Casa del Agua, 'dwelling of water' and arranged problems in the course of demolition. Then, the fact that the Gallery of Casa del Agua as an architecture work of Ricardo Legorreta included his architecture languageswas analyzed. For this, his universalarchitecture languages were examined and how the architecture languages were applied to the Gallery of Casa del Agua was analyzed. As a result, it could be known that languages of composition and languages of emotion consistently shown in his works were represented in the Gallery of Casa del Agua.

Smectites were synthesized from Na-P type and Na-A type zeolites by the hydrothermal synthetic method, and their physicochemical properties were studied. The optimal synthetic conditions for producing smectite were $290^{\circ}C$, 72 hr and $75{\sim}100kgf/cm^2$ in autogenous pressure. pHs of initial reaction solutions for the synthesis of smectites from Na-P type and Na-A type zeolite s were pH 6 and pH 10, respectively. The synthetic smectite was confirmed as $12{\AA}$-beidellite by a series of analysis such as X-ray diffraction analysis with random and oriented mounts, ethylene glycol treatment, and Greene-Kelly test, and their several physicochemical properties were studied.

To select potent probiotics from lactic acid bacteria in Yulmoo Kimchi, an in vitro and stimulated human intestinal model system (SHIMS) test were performed. One Leuconostoc mesenteroides strain from five strains of Yulmoo Kimchi and one Lactobacillus plantarum from 12 strains of KCTC and KCCM were selected according to survival in acidic and bile salts conditions. Between the two species, Leu. mesentroides displayed higher survival activity in a SHIMS test. The strain was identified as Leu. mesentroides by 16S rRNA sequencing and was designated as Leu. mesentroides K01.

Scientific challenges in the field of MR(magnetorheological) fluids and devices consist in the development of MR devices, the mathematical modeling and simulation of MR devices, and the development of (optimal) control algorithm for MR device systems. To take a maximum advantage of MR fluids in control applications a reliable mathematical model, which predicts their nonlinear characteristics, is needed. A inverse model of the MR device is required to calculate current(or voltage) input of MR damper, which generates required damping force. In this paper, we implemented test a bench for shear mode rotary MR damper and laboratory tests were performed to study the characteristics of the prototype shear-mode rotary MR damper. The direct identification and inverse dynamics modeling for shear mode rotary MR dampers using multi-layer neural networks are studied.

Most CFD codes, that mainly adopt the heat partitioning model as the wall boiling model, have shown low accuracies in predicting the two-phase flow parameters of subcooled boiling phenomena under low pressure conditions. In this study, a number of subcooled boiling experiments in vertical channels were analyzed using a thermal-hydraulic component code, CUPID. The prediction of the void fraction distribution using the CUPID code agreed well with experimental data at high-pressure conditions; whereas at low-pressure conditions, the predicted void fraction deviated considerably from measured ones. Sensitivity tests were performed on the submodels for major parameters in the heat partitioning model to find the optimized sets of empirical correlations suitable for low-pressure subcooled flow boiling. The effect of the K-factor on the void fraction distribution was also evaluated.
