  • With emergence of smart technologies(e.g., smartphones), Location-Based Services(LBS) are expected to provide more enhanced values utilizing consumers' personal information than other smart services. However, in contrast to existing smartphone applications, LBS could raised severe consumer's privacy concerns because of rapidly changing information sensitive to consumers. In this context, the purpose of this study is to explore relationships among privacy concerns reduction, trust and intention to use LBS by examining the effect of precedence factors(social presence, reputation, mobile literacy, ability of information control) of privacy concern reduction. In addition, the study investigates the role of personal innovation as a moderating effect between privacy concern reduction and intention to use LBS. The results showed that the proposed precedence factors of privacy concerns with a exception of Mobile Literacy had a positive impact on privacy concerns reduction that then positively affected trust and intention to use LBS. In addition, the relationship between trust and intention to use LBS was significantly supported. Finally, personal innovation as a moderating effect significantly influenced the relationship between privacy concern reduction and intention to use LBS. This study is expected to be a reference for a subsequent study about the spread of LBS application of smartphone. Also, the finding of this study is meaningful for helping service direction to firms providing LBS.

  • Since luxurious apartments have appeared in Korean common housing, there have been a series of stages in reflecting the demands of residents. However, lifestyles have been restricted to a typified pattern because housing was provided extensively during a short period. The ensuring of residency in common housing lies in seeking how to utilize a given space to the maximum. In the presence of residents, the characteristic of today's housing is not merely satisfied with residents, but provokes the function of a new supplier. Residents are changing by situation (economic, social, cultural, and family types), yet housing is falling short of the change. In particular, it is necessary to closely observe the change in housing by time and space in accordance with both psychological and physical changes of family members. Therefore, this study aims to furnish an opportunity to prepare the foundation of alternatives, which may cope with the future in housing design and furniture design through the latest cases at home and abroad as well as a theoretical background of issues concerning a variable system, which will suit the demands of residents.

  • The $18^{th}$ century's Industrial Revolution brought about influx of commerce, industry, and agricultural population into the urban areas, entering the $19^{th}$ century. Quality of rural communities declined, and the exploding population in the cities gave rise to various problems. 'Mietskaserne' Blockhousing was constructed by the 'Hobrechtplan', but led to social problems such as poor living conditions, insufficient sunshine due to overcrowding, slums due to incomplete urban infrastructure, epidemics, and so on. Starting in the early $20^{th}$ century, Berlin has driven forward a remodeling plan under the motto of 'critical reconstruction (kritische Rekonstruktion)'. It is performed in the place, which represents the vicissitudinous history of Berlin with site plans coexisting past with presence, using modern vocabulary of architectural forms. Reconstructing a city is a process which not only raises the economic value of each building consisting a city, but also a redevelopment process that brings out cultural value of an era. When a new era emerges buildings get reconstructed or rebuilt, and thereby form the identity of a city by reflecting its society, culture, politics, economy, and history. Old German architecture were not destroyed or rebuilt recklessly just by the fact that they are functionally or aesthetically outdated. Each building is treated as precious cultural heritage reflecting the history. This is how Berlin is being transformed today.

  • Methylisothiazolinone (MIT) has been used in combination with methylchloroisothiazolinone (CMIT) for cosmetic products such as shampoo, body lotion, and skin care products. The mixture of CMIT/MIT has been found to cause allergic contact dermatitis and is thus no longer permitted for use as a preservative in leave-on cosmetics. However, MIT itself was approved as a stand-alone preservative at a maximum concentration of 100 ppm as the toxicity was derived from CMIT rather than MIT. However, in many countries, allergic skin irritation caused by MIT remains a social concern. In this study, skin irritation was assessed for the presence of MIT, propylene glycol, and their mixture using a 3D human skin model $EpiDerm^{TM}$. Although non-diluted MIT causes serious skin toxicity, skin irritation was not observed at a concentration of 100 ppm, the maximum permissible level for cosmetics and personal care products according to European regulations. Propylene glycol, the most widely used vehicle for MIT, did not cause skin irritation in the 3D skin model. The results are expected to provide information for regulatory policies and guidelines on the use of biocides in consumer products.

This study was conducted to compare the infants' temperament and health problems according to the presence of maternal postpartum depression. Methods: Data were collected from May to October in 2009. The sample was 137 mothers at one month postpartum. The Edinburgh Postpartum Depression Scale (EPDS) was used to assess depressive symptoms.

They showed lower scores on the amenability, rhythmicity and persistency and higher scores on activity in temperament. Also, infants of depressed mothers reported more infant health problems at one months. Maternal depression showed significant negative correlations with family functioning, social support and marital satisfaction. Conclusion: Study findings show that postpartum maternal depression is associated with infants' temperament and health, and thus screening and early interventions for postpartum depression would promote the health of both the mother and infant.

The contents of messages focused on a hypothetical restaurant's cause-marketing activity. Four types of message framing were created: The first two types were varied by the presence and absence of the information about the current cause-marketing outcome, and the second two types were varied by positive and negative framing.
