The purpose of this paper investigate the general definition of Tense and the concepts about Aspect. I consider the correlation between the lexical and the grammatical aspect. Tense is an inflection type of a verb that indicates the time, tense is grammatical categories. Tense has the current tense and the past tense in English. If we recognize aspect as a grammatical category, that the subject of in description will be confined to the grammatical expression. In contrast, when considered as a category of meaning, lexical and grammatical representation is the expression target. Therefore, aspect is stated as a grammatical category. Specially, the aspect of English, there is only a progressive tense and perfect tense. In this case, the progressive aspect is progressive tense and the perfect aspect is perfect tense. Chapter 2, I investigate the definition of the tense of many scholars and define the usage of each tense. In Chapter 3, I exhibit the definition of the Aspect. Aspect is grammatical and semantic one. Tense and Aspect is a simple grammar category, but they have a various spectrum. Therefore, As the definition of the Tense and Aspect becomes clear it will be helpful to students who are received English education. In addition, the definition about tense and aspect needs in variety of areas, more research is needed.

Unlike the era of manufacturing-oriented industrial economy in the past, the era of service economy has characteristics intangible goods center, knowledge universalization, and expansion of needs, and many things that are of the economy are changing. In the past, the change in the environment was not fast, so even after analyzing the changed environment and deriving the talent needed for the company, it was possible to maintain a talent for the organization for a long time, so it is not proactive to build and apply talent. It became difficult to manage effectively. Therefore, in this paper, we conducted a normative study for deriving a desirable talent model rather than a descriptive human resource model. Human resources image suitable for the modern service economy era, the modern economic society and modern spirit were analyzed and reflected. The model in which the two opposing members of the organization, managers and employees, interact intensely and balance dialectically. A desirable talent in a modern organization must play the role of a manager, and the management and talent models in a modern organization can be said to be connected to each other like the front and back sides of a coin. The philosophy of human resources was presented in five dimensions: human, historical, social, economic, and management. The human resource model from eight factors: mastery, rationality, wisdom, customer orientation, innovation, flexibility, autonomy, collaboration. This study suggested that general talent model may vary depending on the company's type, empirical follow-up studies are needed the talents in each company in the future.

high pressure and temperature conditions. However, those results are not consistent with one another, and phase boundary between ilmenite and perovskite phases determined only from the quenching method may be not so reliable at all. Therefore, in-situ high pressure-temperature (hP-T) X-ray diffraction measurements were performed up to 19 GPa and $700^{\circ}C$ in a large volume press apparatus using synchrotron radiation. Experimental results show that perovskite phase is stable at pressures above 16 GPa, and transforms back to $LiNbO_3$phase near 15 CPa at room temperature, and that the perovskite-ilmenite transition is back and forth near 15 CPa at $500^{\circ}C$. LiNbO$_3$phase transforms to ilmenite at 13 CPa and $300^{\circ}C$ and at 10.8 CPa and $400^{\circ}C$, respectively. These data indicate that $LiNbO_3$phase may have a stability region in the hP-T phase diagram and that the perovskite-ilmenite phase boundary would be quite different from that previously reported.

A phase transformation study on a synthetic amorphous diopside, $(Ca,Mg)SiO_3$has been carried out up to ∼30 GPa, and ∼$1000^{\circ}C$ using a diamond anvil cell and YAG laser heating system, respectively. A starting amorphous material shows a direct transition to cubic $(Ca,Mg)SiO_3$perovskite at high pressure, which contradicts to the crystalline diopside phase transformation sequence disproportionating into mixtures of the orthorhombic$ MgSiO_3$perovskite and the cubic $CaSiO_3$perovskite phases. This discrepancy might be due to the different starting materials as well as the temperature variations at each specific experiment performed. The present phase transfor mation sequence would modify the mineralogical assemblage in the Earth transition region and the lower mantle depending upon the pressure, temperature and the oxygen partial pressure.

We prepared monodispersed spherical silica microgels by controlling various conditions of emulsification procedure using a lab-scale membrane emulsification system equipped with SPG (Shirasu porous glass) porous membrane having pore size of $1.5{\mu}m$. We determined the effects of process parameters of membrane emulsification (ratio of dispersed phase to continuous phase, sodium silicate concentration, emulsifier concentration, dispersed phase pressure, stirring speed) on the mean size and size distribution of silica microgels. The increase of the ratio of dispersed phase to continuous phase, dispersed phase pressure and sodium silicate concentration led to the increase in the mean size of microgels. On the contrary, the increase in emulsifier concentration and stirring speed of the continuous phase caused the reduction of the mean size of microgels. Through controlling these parameters, monodisperse spherical silica microgels with about $6{\mu}m$ of the mean size were finally prepared.

A study on the electrochemical reduction of uranium (VI) to uranium (IV) was carried out in the mixed phases of an organic phase with uranium (VI) and aqueous phase of nitric acid by use of a highly packed glassy carbon (GC) fiber column electrode system, and a model for in-situ electrolytic stripping of uranium (VI) was suggested. The electrochemical reduction of uranium (VI) occurred faster in organic phase than in aqueous phase of the mixed phases. The uranium stripping yield increased and then became constant with the increase of organic flow rate of the electrolytic system due to the increase of diffusion resistance of uranium ions in the organic phase into the aqueous phase. Aqueous flow rate, on the other hand, didn't affect the total uranium (VI) reduction current in the system. The system combined with electrochemical reduction was confirmed to be much more effective than the simple system without it in stripping uranium.

In this research, speciation of phosphorus in sediment and overlying water dependent upon pH and ORP(Oxidation Reduction Potential) was studied. Three possible conditions were simulated: open system with circulation, closed system with stratification and closed system with sand capping on the sediment. Phosphorus release rate from sediment was increased for both open system and closed system if pH was less than 6.0. Phosphorus concentration for closed system was increased from 0.9 mg/L to 0.51 mg/L, and stabilized at 0.34 mg/L if anaerobic conditions were maintained in the overlying water. When sand capping was implemented, phosphorus concentrations of overlying water were maintained less than those of closed system.

침질탄화처리는 표면경화처리의 화학열처리 종류로서 지난 수 십년동안 많이 사용된 방법이며 값싼 철강재료 즉 보통탄소강, 저합금강 등에 내마모성, 내부식성 및 내피로성 향상에 사용되어 왔다. 그리고 자동차 부품, 기계류 부품, 공업용 공구 등에 적용할 수 있으며 염욕 및 가스를 매체로 사용한다. 침질 탄화처리는 질소와 탄소가 동시에 철재료로 확산 침투하여 최표면에 탄질화물의 화합물층을 형성하고 화합물층 아래에 확산층을 형성하는데 일반적으로 화합물층이 단상의 $\varepsilon$화합물일 때 내마모성과 내부식성을 확산층이 내피로성질을 향상시킨다. 이러한 염욕과 가스 침질탄화 처리에도 불구하고 플라즈마 화학열처리는 가스방법에 비해 현저하게 가스 소모량이 적고 에너지 효율이 높으며 현제 문제시되는 환경오염이 전혀 없기 때문에 크게 각광받고 있다. 현재 플라즈마 침진탄화처리에 많은 연구를 하였음에도 불구하고 단상의 $\varepsilon$화합물층을 형성시키는 어려운 문제점으로 남아 있으며 대부분의 화합물층은 최표면의 $\varepsilon$상과 ${\gamma}$'상으로 구성되어 있고 이러한 혼합상의 화합물층은 $\varepsilon$상과 ${\gamma}$'상의 방위가 서로 불일치하기 때문에 마모시에 미소크랙을 유발시켜 내마모성을 저하시키는 요인으로 작용한다. 따라서 본 연구에서는 CH4 가스를 사용하여 내마모성과 내부식성을 향상시키는 단상의 $\varepsilon$화합물층 생성가능성을 고찰하고자 하였다. 침진탄화 처리시간을 변화시켰을 때 화합물층의 생성은 ${\gamma}$'상으로부터 시작되고 $\varepsilon$상은 즉시 ${\gamma}$'상을 소모하면서 생성되어 일정시간이 지난 후 $\varepsilon$상은 안정화되며 질소가스농도가 증가할수록 화합물 층내의 $\varepsilon$상분율은 역시 증가하였다. 한편 CH4 가스농도는 처리되는 강종에 따라 차이를 보이며 적정 CH4 가스농도를 초과시에는 $\varepsilon$상 생성은 억제되고 시멘타이트상이 생성되었다.

Morphology of injection molded polymer blend was investigated by experimental and theoretical approach. In experiments, the effects of injection speed and injection temperature on the morphology of injection molded MPPO/Nylon 6 blend were investigated. The morphology distribution across the part thickness was clearly observed in injection molded blend. We could observe several distinct regions across the thickness of molded part: skin layer, subskin layer and core region. The skin layer where the dispersed phase is fine and highly deformed to the flow direction is observed to be located near the part surface. The subskin layer located at inner region of the skin layer also observed. In the subskin layer, the dispersed phase is coarser than that of skin layer and deforms to the flow direction. Based on the experimental results, the calculation scheme to predict the morphology of injection molded polymer blend was suggested. The morphology of injection molded polymer blend could be predicted in corporation with the result of flow analysis obtained from commercial software for injection molding process and the theory of drop behavior under the flow. The suggested calculation scheme could predict the effect of injection conditions on the morphology of injection molded parts.
