The purpose of this study is to identify poorly understood factors related to the recent rapid decline in fertility in Korean society. Along with Becker's child demand theory, personal psychological traits, such as independence, nurturance, and affiliation, were given special attention in this study. We examine the processes of resource transfers between married women and their parents on childbearing intention in order to verify the effects of both factors. Five hundred and seventy-six women in their early stage of marriage from the 2009 wave of the National Survey of Marriage and Childbirth were analyzed. Main results of the study are as follows. First, Becker's child demand theory is not supported. Instead, the women who were not given economic support from their parents in getting a residence at the time of their wedding turned out to be more willing to have a child, potentially because they were more independent. Second, the women who provided caretaking and emotional support to their parents had higher childbearing intentions, potentially because they were more nurturing. In conclusion, these personal psychological variables are important in understanding the childbearing behavior of women. We suggest that the government should pay more attention to the micro-personal factors raised in this study when executing policies to reverse the current trend of low fertility.

This study was surveyed from May to October, 2008 in order to classify type distribution and evaluate the function of inland wetland as a ecological axis in Chungnam province. Assessment was done by modified-RAM (Rapid Assessment Method). RAM is consisted of total 8 functions and divided into high, moderate, low. The conservation grade of RAM is divided into 4 grades; absolute conservation, conservation, improvement and restoration. Throughout survey on total 13 wetlands of Lacustrine, Palustrine wetland which are distributed in Chungnam province, their function was assessed. As result, the 2 wetlands were judged as absolute conservation grade by assessment of 8 functional contents, and 7 sites were improvement wetlands and 4 sites were conservation wetlands. The function of wetlands assessed as conservation grade showed high in water quality protection and improvement. Also, showed high in vegetation diversity, wildlife habitat and aesthetic recreation. Meanwhile, showed low in Water quality purification, Shoreline/Stream Bank Protection. Of wetlands evaluated as conservation grade, Jeong-juk Ji and Dun-ri reservoir were assessed as absolute conservative area. These wetlands are essential to be managed continuously as a area having high ecological value.

The mobile market in South Korea is about 4trillion and the social commerce market is also growing. Social commerce market was started from small venture company and in nowadays, its status is getting higher enough to compete with such as Gmarket and 11st. As social commerce market is rapidly growing, the interest of consumer is getting higher and we need to research about how consumers to recognize and make a purchase. For the research, I set hypothesis about consumer's recognition about social commerce, shopping experience, purchasing disposition, a trust influence on purchase attitude and we analyzed through actual investigation. I did a survey for male and female in 20s. An analysis result showed that the recognition about social commerce, shopping experience, purchasing disposition and a trust can affect on purchasing satisfaction. The most popular category in social commerce market was restaurant and fashion and I also found that consumers visit social commerce market in case of need rather than regular visits. I expect a rapid growth of social commerce market as an advance of smartphones. I hope this research could help for to establish marketing strategy by understanding characteristics of social commerce market and consumer proneness.

Smart phones have brought rapid changes in this competitive world. Smart phone application developers are trying their best to consider the customer requirements in the most efficient way while considering all its attributes. However smart phone service quality has been given less consideration comparatively during the last few years. This paper proposes a measurement method for improving service quality of smart phone application. This method combines the service quality performance model (SQPM) and process capability index (PCI). The service quality performance model is used to identify service items that require improvement. Process capability index is used as a measure for prioritization of those improvements. Case study was carried out to search out important communication application service attributes. customer satisfaction level data was collected for users who used the application service. A total of twenty four service attributes were found during this survey. Using the joint approach of SQPM and PCI, five significant service attributes were prioritized for service quality improvement.

This study aims to create a disaster management system after an earthquake. Japan's earthquake disaster management system, including the Disaster Countermeasures Basic Act, addresses all of the disaster phases of prevention, mitigation, preparedness and emergency response as well as recovery and reconstruction with roles and responsibilities among the national and local governments clearly defined. Korea's earthquake disaster management system are including the Disaster Countermeasures Basic, but when the 9.12 earthquake occurred, problems such as insufficient early response, study on the earthquake lack were revealed. This study conducted a field survey and analyzed coping process after Po Hang earthquake. Therefore, this study have found that Disaster Management Headquarters are operated rapidly. They are coped with urgent safety inspection for damage facilities and soil liquefaction with advanced equipment. And The headquarters interviewed with victims. So they found out What the victims needed. However, when carrying out relief activities, Research of temporary housing and allocation of donations was not rapid. Further, this study have found that earthquake specialists were lack and disaster information transfer was not working. This study will be utilized as fundamental data in planning disaster management system after an earthquake.

This study analyzes the body sizes of young boys in order to categorize a sizing system for middle and high school uniforms. The study was based on the $6^{th}$ National Anthropometric Survey (Size Korea 2010) data. The sample size consisted of 2,317 boys between the ages of 13 and 18 years. Most measurement items increased significantly relative to age and there was rapid growth between the ages of 13 and 14 years. The growth for the chest and hip was more than the waist. The drop value 1 (difference between chest circumference and waist circumference) and the drop value 2 (difference between hip circumference and waist circumference) increased remarkably from the age of 13 to the age of 15. Therefore, the waist size decreased and chest and hip became wider relative to the age increase. Middle school students had a smaller chest and hip circumference than high school students in the comparative body measurement results for middle school students (13-15 years) and high school students (16-18 years) of the same height group. The somatotype of high school students showed a long trunk length, broad chest and shoulder.
