There have been many discussions on the importance and part of quality in the marketing field. It also has been an effort in the cooking field to understand how the quality, recognized by customers, influences customer satisfaction in the process of serving western food. This study is a theory about evaluation methods of western food. It can be summarized in three views as below especially with sensuous evaluation methods. First, it is decoration. Visual factors, such as a receptacle and the amount of food in it, the arrangement of food colors, gloss of food, steam arising of from food, additional garnishes on food should be harmonious. Second, it is a flavor. The factors like the taste and smell of food, and feeling of food in the mouth can be evaluated with the taste and the smell. Third, it is texture. It is considered with the sense of touch, the motor sensation in the mouth and the hearing sense. Especially the sense of touch involves feel of receptacle when it is hot or cold as well as feel of food. This study has been conducted for providing customers with higher-quality western food, which is based on a theoretical study about evaluation methods. During the study, the limit was found that there is no measuring instrument, since the study was restricted in a theoretical work. For more accurate research, the measuring instrument should be developed through the positive research.

The purpose of this study is to investigate the speech act realization of speculative expressions and to present their teaching-learning contents. It is hard for Korean learners to use speculative expressions appropriately because there are various similar expressions and their meaning is distinctive in detail. This study describes speech act realizations of '-는 것 같다, -을까, -나 보다, -을걸'. All these forms have the meaning of speculations, so they are mainly used to present uncertain information or thoughts of speaker. But they show distinctive aspects. '-는 것 같다' is mainly used to present contents contrary to their counterparts' opinions or irritating for their counterparts. It is used as polite forms because it conveys meanings of uncertainty. Especially in these contexts, it performs the refusal speech acts. '-을까' has the characteristic feature in the complex forms such as '뭐랄까', '뭐라고 할까' and it performs request speech acts more frequently than '-는 것 같다'. Also it is used to express the speakers' opinions contrary to their counterparts'. '-나 보다' expresses speaker's speculations based on hearer's conditions or his speech, so it is used to respond to hearer actively and express interests unlike other speculative expressions. '-을걸' isn't used to perform request, to express interests to hearer. However, it is mainly used when speaker has the contrary assumptions or expectations to hearer's. Based on the analyze, this study presents and grades teaching-learning contents of speculative expressions.

The application of mindfulness is increasing in corporation for business innovation. However, the influence of mindfulness has not been confirmed for employee in detail. Mindfulness is the awareness that arises from paying attention in the present. We often experience uncertainty abounds about what the information technology is, how well it works in the process of using information technology. According to the definition of mindfulness, mindfulness can deepen employee's thoughts and understanding of information technology and will provide a clue to the solution of the issue. This study focusses on impact of mindfulness on IT usage behavior, particularly on IT continuance usage. Research question of this study is whether mindfulness impact perceived factors related to IT continuance usage. The study of relationship between IT and mindfulness will have meaningful results because both IT and Mindfulness are aimed at corporate innovation. Based on most recent theory in IT continuance usage, called by Decomposed Expectation-Disconfirmation Model, we established hypotheses and examined the impact of mindfulness on perceived factors in process of IT continuance usage. For empirical analysis, we collected 303 employee samples and conducted Structural Equation Modeling for path analysis. We showed that mindfulness has a positive impact on perceived usefulness, usability and usefulness confirmation, usability confirmation. We also confirmed that antecedent of satisfaction is perceived usefulness, perceived usability and usefulness confirmation, usability confirmation, and satisfaction is the cause of IT continuance usage. We suggested academic and practical implication based on empirical analysis results. In academic perspective, we found the role of mindfulness in process of IT continuance usage. From practical point of view, we suggest to use of mindfulness program for IT continuance usage in corporation.

It is well known that the degradation transformer oil is mainly effected to the failure of transformer. In this paper it is discussed the characteristics of the degradation sensor checking transformer oil condition in live line. The degadation sensor composed with base ring, electrodes and porous ceramic passed through the transformer oil and checked the transformer oil condition with sensor's leakage current. It is important to minimize the leakage current of base ring and connection parts. To investigate the leakage current of base ring and connection parts it is examined the characteristics of V-T-I and DC 2 KV and other examinations. It is verified that ionized transformer caused by the expansion of oil temperature increase in the leakage current of porous ceramic sensor. It is certificated that the leakage current of other parts of porous ceramic is very small (about 2 %) than the porous ceramic and it is confirmed that the leakage current in porous ceramic is changed sensitively according to the new oil(NO) and and the degradation oil(DO).

Taurine, amino acid, chemically known as 2-amino ethane sulphonic acid was discovered more than two hundred years ago from ox bile. it is widely distributed in both mammals and nonmammals. It is found in considerably high amount in hUl11an: a normal adult of 70 kgs contains about 70 grams of taurine. Taurine with this much concentration, is involved in almost all life processes. Its deficiency causes several abnormalities in major organs like brain, eye and heart. Taurine-bone interaction is latest addition to its long list of actions. In bone cells, taurine is also found in high concentration. Taurine is found to help in enhancing the bone tissue formation which is evidenced by increased matrix formation and collagen synthesis. Besides stimulating the bone tissue formation, it also inhibits the bone loss through inhibiting the bone resorption and osteoclast formation. Thus, taurine acts as a double agent. In addition to these two major actions of taurine in bone, it also has beneficial effect in wound healing mld bone repair. Taurine possess radioprotective properties, too. As it is a naturally available molecule, it can be used as a preventive agent. Taurine has a potential to replace bisphosphonates which are currently in use for the inhibition of bone loss but this needs in depth study. As taurine is involved in bone formation and inhibition of bone loss, a detailed study can make it a single marker of bone metabolism. All these taurine-bone interaction is a symbol of their deep involvement but still require further extension to make taurine as a choice for tile sound bone health.

Transmission loss of specimen is calculated by measuring energy of incident and transmission and using reverberant room of large size. But normal measurement of transmission loss has trouble because it is actually demanded that large area and specimen of certain size is satisfied with condition of diffused sound field. Especially, in case of mechanical component, interested frequency band is mid-frequency band between 500 ~ 2k Hz, and it is used to be available to minimize a reverberation chamber under conditions satisfying acoustic one because production of specimen for transmission loss measurement has limit. But, as in semi-reverberation room, it is difficult to satisfy condition of diffuse sound field and modification factor is applied to complement that. Correction factor when measuring transmission loss using semi-reverberation chamber is required accuracy because it works as main factor determining reliability of reuslts on transmission loss. In this study, it is analyzed that an effect on correction factor based on varying materials and sizes of specimens in order to deduction of it. Also It is confirmed that applied by elicited correction factor with actual railway vehicle's floor has reliability.
