El presente trabajo tiene como objetivo proporcionar una explicación simplificada pero suficiente sobre el uso de las formas pronominales de tratamiento en los países de habla española, y hacer una propuesta para la enseñanza de los pronombres de tratamiento en la enseñanza del español en Corea. En la actualidad, en el mundo hispánico existen varios sistemas de tratamiento pronominal. La distribución dialectal de sus formas es bastante complicada. En la norma de España se usa el tú para el trato informal en oposición con el usted para el trato formal. Mientras tanto, en Hispanoamérica se usan el tú y el vos para el trato informal, y el usted para el trato formal. Sin embargo, la mayoría de las gramáticas didácticas y manuales no ofrece una explicación suficiente en cuanto a las diferencias de las formas y el uso de los pronombres de tratamiento. En Corea, en la mayoría de las clases de español se enseñan sólo la norma de España, que es minoitaria entre la comunidad global de hispanohablantes. Eso no les permitiría a los estudiantes tener una interacción exitosa con personas que dominen otras normas del tratamiento pronominal. Para que los alumnos tengan una competencia comunicativa que sea lo más universalmente válida, es necesario ofrecer una perspectiva de los fenómenos lingüísticos y culturales que toman en cuenta las variedades del sistema del tratamiento pronominal que se usan hoy en día en el dominio hispánico. Por último, los intereses y el nivel de los alumnos son variables que determinan qué o cuánto hacer en la enseñanza de las formas pronominales de tratamiento.

Although natural soil deposits hat.e been consolidated under Ko-stress system, the soil behavior has been predicted in laboratory from the results of tests performed on specimens consolidated under an isotropic stress s).stem. A series of undrained triaxial compression tests are performed on remolded specimens of clay consolidated under both types of stress systems, and the results at.e compared. One dimensional consolidation history induces anisotropy in clalrs, which is called as the stress induced anisotropy. However, if the clays would be reconsolidated under isotropic stress system. the anisotropy of undrained stress비h would be decreased with decrease of overconsolidation ratio. Undrained shear strength of norma]Iy consolidated clay depends on consolidation methods. Both the Rutledge hypothesis and the study of Henkel and Sowa do not agree with the test results obtained in this paper. In addition, a new theory is explained about the relationships between consolidation stresses, water contents and undiained shear strength.

고분자 복합재료들은 오늘날 광범위하게 마찰 부위들에 응용되고 있다. 다양한 첨가제와 보강재들이 고분자 물질들에 넣어져 강도와 마모 특성들을 향상 시키고 있다. 예를 들어, 다양한 복합재료들로서 현재 입수 가능한 것에 베어링 재료들이 있으며 이에 포함되는 것이 자체 윤활 보강 플라스틱 들이며 이들에는 고체 윤활제, 즉, 테플톤, $MoS_2$, 혹은 흑연가루들이 첨가된다. 실험적 그리고 이론적인 연구들이 여러 조건들에서의 섬유 보강 복합 재료들의 마모 거동에 대하여 보고되었다(예를 들어, 미끄럼 마모, 연마 마모, 입자 충격 마모, 비빔 마모). Tsukizoe와 Ohmae의 보고에 의하면 탄성계수 탄소섬유 복합재료는 가장 적은 마모가 횡단 방향(Transverse)에서 있고, 고 강도 탄소 섬유 복합재료는 길이 방향(Longitudinal)에서 있다. 가장 많은 마모는, 고 탄성계수 복합재료는 길이 방향에서, 고 강도 섬유 복합재료는 횡단 방향에서 잇다. 그들이 또한 발표한 것은 양쪽의 고 탄성계수와 고 강도 섬유 복합재료들의 수직방향(Norma)에서 눌러 불음(Seizure)가 일어났다고 한다.

Heterophil (H) to lymphocyte (L) ratios and durations of tonic immobility (TI) were measured to assess stress and fear responses, respectively, in broiler chickens provided either 12 h of natural lighting (12L) or 12 h natural lighting and 12 h of supplementary lighting (24L). Birds illuminated 24L had greater H/L ratios and TI durations than their 12L counterparts. Neither age, sex nor cage level had significant effect on TI reactions.

A composite mechanics for discontinuous fiber reinforced polymer matrix composites(PMC) is analysed in order to predict fiber axial stresses. In continuum approach. frictional slip which usually takes place between fibers and polymers is accounted to derive PMC equations. The interfacial friction stress is treated by the product of the coefficient of friction and the compressive stress norma1 to the fiber/matrix interface. The residual stress and the Poisson's contraction implemented by the rule of mixture(ROM) are considered for the compressive stress normal to the fiber/matrix interface. In addition. the effects of fiber aspect ratio and fiber volume fraction on fiber axial stresses are evaluated using the derived equations. Results are illustrated numerically using the present equations with reasonable materials data. It is found that the fiber axial stress in the center region shows no great discrepancy for different fiber aspect ratios and fiber volume fractions while some discrepancies are shown in the fiber end region.

Smart battery pack (SBP) for notebook PCs was developed using a cylindrical-type lithium ion battery. Batteries were connected with three serial and two parallel, the nominal capacity and the maximum load of SBP was 4,000mAh and 4.0A, respectively. The SBP was composed of a protection IC, by which safety of lithium ion batteries is maintained against overcharge, overdischarge and overcurrent, and a smart IC, which calculates the remaining capacity and the remaining run time. In matching test on notebook PC using Battery Mark 4.0, real and smart data of END voltage coincided nearly and LB and LLB signal worked norma]]y. And there were errors of less than 1% between the real and the smart data on the residual capacity in the charge and discharge test.

We synthesized amphiphilic material including dye skeleton, p-phenylenediamine(PD) by attaching norma-decyl group of two strands at a part of coordinating atom, for obtaining reasonable design of LB uniform films. The synthesis of this compounds was quantitatively carried out under ultra pure state. This product was identified with FT-lR spectroscopy, UV absortion spectroscopy, and $^1$H-NMR spectroscopy, respectively. When manufacturing monolayer, we confirmed molecular area from pressure-area($\pi$-A) cutie of thiscompound onto the surface of the water. The spectroscopic approach also has done by UV absortion spectroscopy. It was shown that PD-complex LBfilms were deposited well with monolayer thickness. The conductivity based on I-V characteristics of PD-complex LB films were in the range of 10$^{-10}$ S/cm at room temperture. The microscopic properties by AFM, showed the good orientation of various monolayer or multilayer molecules
