The purposes of this study is examining a wearing tendency of a progressive multifocal lens. We measured refractive error values using subjective and objective refraction method with subjects in 40-65 ages. Also, we investigated and analyzed distribution of addition power and wearing tendency of progressive multifocal lens. Detected addition powers were ranged of +0.75D - +3.00D. In case of average addition, they were detected with +1.18D in 40's, +1.55D - +1.97D in 50's and +2.38D in above 61's age. The distributions of visual ability at a distant were measured that the hyperopia and hyperopic astigmatism 43%, the myopia and myopic astigmatism characteristic astigmatism 7% appeared highly with 36%. The male who uses the interior aspect multi focal lens with the short-range work were appeared the male 20%, the woman 19%.

In traditional studies on North Korea, conservative media in South Korea generally report and have an attitude toward anti-North Korea. It is a similar context as South Korea's conservatives view the U.S. and Japan more closely and positively than North Korea. This study is about how the reporting frames and information sources on North Korean science and technology in South Korea's conservative and progressive media differ and show trends. As a result of analyzing the reporting frame on North Korean science and technology by conservative and progressive media, progressive media showed similar trends or slightly positive responses to North Korean science and technology. But the reanalyzed result after dividing it into conservative and progressive governments, the opposite result came out. In the conservative government, the progressive media dealt with very positive aspects of North Korea's science and technology, and in the progressive government, there was a clear tendency to report negative rather than positive. What can be inferred from this is that the progressive media of South Korea had at least quite different directions of the progressive government in dealing with North Korean science and technology, but rather close to anti-North Korea. It is difficult to reach a hasty conclusion because this study has not dealt with all the press and only 10 years after the Kim Jong-Un regime. Nevertheless, this study may provide implications in that it is the first study to analyze how South Korean conservative and progressive media frame North Korean science and technology.

The aim of this study is to examine the expression of the meaning of tradition and the archetype of korean image in it in order to find out korean image on reflection of the meaning of tradition. The results are as follows. 1) The nature of tradition illuminates the past, and lights up the present. It cannot be a portrait which enable to have a future prospect and also a cornerstone a tutore pave the way for of the better direction. 2) It's meaning like to say that korean style it self is considered as an expression of tradition. But it korean tradition has a tradition course in a dialectical way, new creation will be possible, 3) The social and cultural aspects change as time goes by through the tendency of society and it's culture we can get some imformation about the inner spirit of human being. The inner spirit of human being is the spirit of our nation so that we can get oringinality from the culture of our nation. 4) On the aspect of idea oganic system must be visualized on the basis of scale whichs accustomed to our emotion. 5) We can also find out the growing tendency that architects are willing to express the typological image as spacial arrangement and ideology of the Korean image to their works recently. It can be defined that it is a progressive tendency for the expression of Korean image in contemporary architecture. This study is needed to have move practical and concrete examination in order to approach more ideologically the expression of the sense of tradition.

The aims of this study are to classify the life styles of urban housewives, to see their relationship between life style and demorgaphic variables, and also to see the relationship between life style and dietary patterns. This study has been performed by a questionsire about life style, demographic variables and dietary pattern. The selected samples were 475 housewives. The data were analyzed by factor analysis, cluster analysis, Duncan test, X-test and F-test. Life style is classified into 4 types: temporary enjoying type, passive irrational type, realistic conservative type, actual progressive type. The housewives who are in temporary enjoying type usually do randomly and don't think seriously something. And they have tendency to enjoy themselves. Therefore they don't have any plan for dietary behavior. The passive irrational type's housewives have no consistancy in their life and they do everything temporarily. The housewives who are in this type have relatively low incom, low level of education and they are high in age. The people who are in realistic conservative type act reasonably and elastically everything. They use convenient food very much, because they are willing to save time to make them. The housewives who are included in actual progressive type are well organized and planned in dietary behavior than others, when they dine out, they eat with family together in general, they usually use only a kind of western sauces and convenient food. They are relatively young, highly educated, and they are high income group. In conclusion realistic conservative type and actual progressive type are both relatively desirable type in dietary behavior, but in temporary enjoying type and passive irrational type, there, have to do some guide and education about managing family resources and dietary behavior.

Remarkable progress had been made in both technology and production of optical elements including aspheric lens. In the past, precision optical glass lenses were produced through multiple processes such as grinding and polishing, but mass production of aspheric lenses requiring high accuracy and having complex profile was rather difficult. Against such a background, the high-precision optical GMP process was developed with an eye on mass production of precision optical glass pasts by molding press. This GMP process can produce with precision and good repeatability special form lenses such as for cameras, video cameras, aspheric lenses for optical items. In this study, Design Of Experiment(Taguchi method) was adopted to find a tendency of molding conditions that influence formability. Three main factors for molding conditions were selected based on pressure at pressing stage and temperature, pressure at cooling stage. Also, the DOE was carried out and the interference patterns were measured to evaluate the formability of GMP process. From the results, it was found that the cooling pressure is the most sensitive parameter for progressive GMP process.

With increasing tendency of incidence and interest for the late onset schzophrenia, concerns about whether this disorder is etiologically or phenomenogically distinctive entity or not have increased also. To clarify the disease entity of the late onset schzophrenia and the role of structural brain changes in its etiology, authors tried to prove following hypothesis : Are there any evidences of structural brain changes in the lateonset schizophrenia? ; If present, are they not different from those of the early-onset schizophrenia or progressive schizophrenia? ; And are they not different from those of senile dementia? Subjects were 6 patients with the late-onset schizophrenia, 6 patients with the early-onset schizophrenia, 6 patients with progressive schizophrenia, 6 patients with Alzheimer's dementia, and 6 controls. We measured regions of interest of the magnetic resonance images by computer assisted planimetry using the AutoCad and digitizer. Our study results may suggest that the third ventricular enlargement and a reversal of normal difference between left and right temporal lobe and left-right difference in posterior lateral ventricle are common brain pathology for all types of schizophrenia including the late onset schzophrenia. And also suggest that brain structural changes of the late onset schizophrenia are related with neurodevelopmental abnormality rather than degenerative change.

A shield connector is an automotive electrical component that is used to connect electrical wiring in a vehicle. This part is made by progressive pressing using a phosphor bronze material with high electrical conductivity. The shape of the product is not complicated, but plastic forming techniques are required, such as deep drawing and bending, as well as shearing techniques such as piercing and notching. The finite element method was used to model the process. The strip layout design stage of the progressive die makes it possible to examine the thickness change, the stability of the forming process, and the spring-back. As a result of this analysis, it is possible to predict the correction values for the tendency of cracks, wrinkles, and incomplete plastic deformation, and to identify possible problems in advance. As a countermeasure against the forming error caused by the drawing process analysis, the drawing shape was modified and applied in the process design. For effective material utilization, a 3D strip layout was designed using an optimized blank shape based on nesting. The results improve the crack stability and spring-back of shield connector products produced through progressive pressing.

This study was focused on the prediction of the approprite tool life by clarifying the correlation between progressive drill wear and AE signal. on drilling SM45C the following results have been obtained; RMSAE, AE CUM-CNTS had a tendency to increase slowly according to wear size, at 1000rpm, 150mm/min However, these increased suddenly in the range of 0.20~0.22mm wear, about 102 holes and had a tendency to go up and down until the drilling was impossible. The sudden increase of AE signals shows that something is wrong and it is closely connected with drill wear and chipping. It also makes the working surface bad From the above results, AE signals could be used to monitor the drill's condition and to determine the right time to change tools.

This study is concentrated on the specified relationship between the contemporary art and the interior design by investigation their situational connections through the expresison of their works. Each fields of modern art makes expressive situation more complicated and transforms its unintelligible and expressive outputs variously. The expression is the basis of the incompatibility of the modern art which features the ambivalence of the various tendency and the characteristics of the artists works as well as the disappearance of the typical genre of the art. The new expression such as the spatial recognition of the paintings and the participatio of the real, expreimental examples of the modern art enlarges its realm. The field interior design which has the close relationship with the fine arts need to make a new discussion or a theory among the progressive expression and the various tendencies of the art. Through this research, by reviewing the intermixed and expressed features of the artists works and designers projects which went far beyond the concepts and genre, the interrelationship between expression tendency of the contemporary art and the interior design has been specified.

Bronchioloalveolar cell carcinoma accounts for less than 6% of all primary lung cancer but has distinct clinical and radiological features and unusual pathologic appearance. The characteristic features are its peripheral location and tendency of rapid progression to diffuse type via aeroginous and lymphatic route without surgical intervention. Among them, mucin secretory type bronchioloalveolar cell carcinoma is the rarest and most distinctive. We experienced a case of mucin secretory type bronchioloalveolar cell carcinoma in a 47 year old female with roentgenographic findings of chronic progressive pulmonary consolidation with muliple cavities.
