Anxiety is one of the basic human emotions. From the evolutionary psychology point of view, it is a necessary factor for survival and prosperity of human beings that had been developed throughout time with the history of human survival and development. Anxiety plays the role of protecting one from social or physical threats. In reality, lacking of anxiety showed lots of examples of maladjustments. But the result of over-adjustment, which is overanxious disorder, is definitely disturbing one's survival and growth, and it can lead to anxiety disorder that needs to be treated. Anxiety from the evolutionary psychology point of view, started as a primary adjustment form and it evolves into various types of anxiety disorders that relates to the modern society's characters. Therefore, having the grasp of evolutionary psychology, which can be the base of treating anxiety and anxiety disorders, is very important. So from now on, studies for this aspect would need to be done as integrated and multidisciplinary studies not only by psychiatrists, but by including epidemiologists, psychologists, ecologists, biologists, and neuropsychologists. In this article, the author tried to review and explore the idea of anxiety and anxiety disorders from the evolutionary psychology point of view.

Organizational abilities which assure human resource of excellent quality in enterprise and organization, manages human resource effectively and systematically will be depended on the performance and successful or not of enterprise. The organization which readies to accept changes will survive, the organization makes full use of changes to opportunity and strategy will be a winner. Now when the environment of enterprise is uncertain and environment of management changes, organization should manage HRM in strategic point of view to maintain persistent competition superiority. We investigated how outsourcing affected on organizational performance perception according to inducting BSC from the employees of metro. As a result of the investigation, outsourcing is perceived importantly in study, growth, internal process point of view, but didn't perceived in finance and customer. We guessed that outsourcing would be perceived importantly in financial point of view as a cost reduction. In 5 years from the beginning of metro, it seemed to be perceived importantly, as organizations grow older, perceptions of outsourcing are perceived low because of stabilization of organization and labor's resistance. It is why that the more outsourcing is performed, the more reduction of organization and decrease of employees is expected as much as cost reduction.

The purpose of this study is to analyze the spatial characteristics of business-type-changed parcel in the Hongik-University commercial area, from the view point of commercial gentrification. A commercial gentrification occurs through a business-type-change in a spatial basic unit (microscopic spatial unit such as parcel) of an area which has not been considered in relavent policies and research. So, this study analyzed the spatial characteristics of business-type-changed parcels using the Cox's proportional hazard regression model. The main results of this study are as follows. First, as new developments in the adjacent area occur, the business-type-change probability increases. Second, by the commercial area division, the business-type-change probability is different. Finally, the accessibility is better, the probability is higher. These results could suggest that a consideration of the spatial characteristics form microscopic viewpoint is necessary to understand the commercial gentrification. And these could be used as basic data for a gentrification diagnostic and management system, which can predict gentrification from the view point of business-type-change on the basis of a parcel.

The results of performance analysis by adopting the channel scenarios characterized as Weibull fading for an multicarrierdirect sequence-coded division multiple access (MC-DS-CDMA) system are proposed in this investigation. On the other hand, an approximate simple expression with the criterion of bit error rate (BER) versus signal-to-noise ratio (SNR) method is derived for an MC-DS-CDMA system combining with maximal ratio combining (MRC) diversity based on the moment generating function (MGF) formula of Weibull statistics, and it associates with an alternative expression of Gaussian Q-function. Besides, the other point of view on the BER performance evaluation of an MC-DS-CDMA system is not only the assumption of both single-user and multi-user cases applied, but the phenomena of partial band interference (PBI) is also included. Moreover, in order to validate the accuracy in the derived formulas, some of the system parameters, such as Weibull fading parameter (${\beta}$), user number (K), spreading chip number (N), branch number (L), and the PBI (JSR) values, etc., are compared with each other in the numerical results. To the best of author's knowledge, it is a brand new idea which proposes the evaluation of the system performance for an MC-DS-CDMA system over the point of view with Weibull fading channel.

Food and nutritional survey was made on two kinds of milk (one: 30 samples of bottled milk, the others: 30 samples of prepared milk), which are bottled market cow milk in Seoul city to examine the general ingredients, adulteration and degeneration. The results of survey indicated that the bottled milk delivered to home is relatively better than the prepared milk from the view point of food and nutrition. Moreover the quality of the prepared milk is poor because of adulteration through adding water or skim milk powder in order to increase quantity, consequently the prepared milk is under the nutritional standard. However it indicated that some of the bottled milk are rather inferior from the view point of food and nutrition, so certain measure is required for improving the quality of bottled and prepared milk. Most of the bottled milk and the prepared milk containing Coli-form bacteria have a possiblity to harm the citizen's health as a medium of infectious disease, such a fact is really serious problem from the view point of the national health, considering the general trend of milk consumption increase. It is urgent for us to take a scientific inspection on the sanitary management and take a formidable measure in handling of milk.

The purpose of the this study was to provide the basic information about the formation background of urban squatter and their housing state in Korea. This study was progressed on the basis of socio-historical point of view from after the Korean War to the present time. Therefore, this study considered the meaning of housing for urban squatter in the Korean housing history. For this study, the formation background of urban squatter was divided into five periods. The first one was the period of the policy on the mass migration (1955-1960) after the Korean War. The second period was the period of reproduction of deteriorated residential area (1960-1970) for the continuing mass migration policy. The third was the period of disbanding of deteriorated residential area (1970-1980) for redevelopment. The forth period was before the IMF (1980-1997) broke up the deteriorated residential area. The fifth period was after the IMF (1997-) produced the new poverty due to the unemployment and the business failure. Thus, such social change increased the number of urban squatter and created the new type urban poor.

The purpose of this study is to analyze the factors which have formed gender images in men's fashion since the middle of the 19th century. For this purpose, the images of gender in fashion were analyzed and historical studies about gender images in men's fashion from the middle of the 19th century to the present days were done. Historically images of gender expressed in fashion were masculine image feminine image androgynous image and genderless image. Among those images masculine image and genderless image. Among those image masculine image and androgynous image have been the gender images in men's fashion since the middle of the 19th century. In psychoanalytic view point the factors which have formed the gender images are related with sexual pleasure. Libido for looking narcissism and exhibitionism have produced masculine image and androgynous image in men's fashion, In socioeconomic view point power structure between the sexes have built the gender images in fashion. Masculine image and androgynous image came in to being in men's fashion for the purpose of displaying power or expressing opposition to power structure between the sexes, In aesthetic view point the aesthetic sense of each age about sex have constructed the gender images. Modernism had influence on building masculine image and post-modernism have formed androgynous image in men's fashion.
