This study examines how the long-run relations between housing price and inflation in the United Sates have changed since the year of 2000. Johansen co-integration test, estimation of long-run equilibrium equation, and Granger causality tests are conducted, based on the VECM. Data covers the period from the first quarter of 1975 to the second quarter of 2010. I adopt the recursive estimation method in which the final period of the estimation is expanded by one quarter, starting from the first quarter of 2000. The empirical results are as follows: (1) In spite of the sharp increase of housing price, the long-run relationship of house prices and inflation has been remained stable until 2007, showing that house prices are a stable inflation hedge in the long run. (2) The housing price plunge since 1997 does not seem to be related to the restore of the long-run relationship between housing prices and inflation. (3) Granger causality test results support the hypothesis that inflation granger-causes housing prices with 10% significance level, but reject the hypothesis that housing price granger-causes inflation.

Thus, this study suggests following solutions to youth suicides in South Korea. First, we need to help adolescents to establish their identities based on the traditional ethical principles from both eastern and western cultures. Second, we claim that improvement of educational environment is urgently needed. Adolescents' emotional securities need to be well supported through stabilized family lives and we need to set expanded communication system between students and the school education system to help teenagers lead happier and more active school lives. Lastly, this study suggests establishing a social security system by eliminating potential risk factors and extending the protection factors so that Korean adolescents do not hesitate asking for help to protect themselves when they feel suicidal.

While there is no apparent gender difference on the number of game players and playing time in market survey especially if the age group is under 30, there still exists a strong gender stereotype on female characters with sexual objectification especially in team based battle games. Furthermore, there seldom exists any research on female gamers in this genre. In this paper, we investigate the preference of female characters and reasons of their choice among female gamers with Overwatch and Cypers which are recognized as having enough female players. In Overwatch with 231 responses, subjects prefer 'girl-crush' characters such as non-sexual Ana who age is in 60s. However, in Cypers that does not have female warrior character, subjects' preference is more affected by appearance but those characters with less functional ability are not frequently used in playing. Such practical avatar choice is often discovered among male players thus there is no gender difference in this case.

Recently, Autonomous Vehicle(AV) has been expected to solve various transportation problems. s the problem of environmental pollution become serious, research to reduce pollution is needed. However, empirical research on AV related pollution is insufficient. Based on this background, this study analyzed network performance changes and CO₂ emissions introduc AVs and Electric Vehicles(EV) in eight intersections. The results show that when AVs with internal combustion engines were, the effect of carbon reduction over the network was insignificant. On the other hand, it was that the total amount of CO₂ generated in the network decreased significantly when EVs and autonomous electric vehicles were emissions in the transportation sector.

The study was to investigate the multicultural attitude of nursing students and non-nursing major students. And it was explored influencing factors related with it. This study was used a descriptive comparative designed. Data were collected 3 universities in D city in from Nov. to Dec. in 2012. After receiving the agreement, 309 nursing students and 195 non-nursing major students were recruited. They were asked to fill in a self-reported questionnaire about multicultural attitude. The Korean version Munroe Multicultural Attitude Scale Questionnaire (MASQUE) was used. Cronbach's alpha were .85. Data were analyzed by SPSS 18.0. The mean score of multicultural attitude was 4.44 of 6 points(73%) in all participants. Nursing students' multicultural attitudes scores were equal to other college students'. The factors related to multicultural attitude were the experiences of having foreigner friends, going abroad, attending multicultural events, and contacting multicultural contents. The students who have cared foreign patients were not higher than others in nursing students group(t=.30, p=.76). For nursing students contacting foreigners in clinical practice, it doesn't make a differnce in multicultural attitude. The culturally empowering programs were needed for nursing students to improve multicultural attitudes.

The incestuous assault tends to remain a family secret and not easily be disclosed. Mothers of the victims are usually regarded as the responsible person holding the key to decide whether it should be disclosed or not. Sometimes, therefore, they are blamed with the charge of connivance. The purpose of this study was to explore the essence of mothers' experience of disclosing and to understand the subjective meaning given to this experience. Seven mothers of the female victims of incestuous assault were recruited and interviewed. The collected data was analyzed by hermeneutic phenomenological method. The essential theme of the mothers' disclosing experiences could be summarized as "overcoming pain by going through pain". This major theme contained three sub-themes: "wanting to vent the deepest tormenting pain", "getting hurt again by disregard and indifference from others", "attempting to tear open the festering wound and to feel recovered". Mothers experienced the disclosing process as revisiting the hidden wound to find the meaning of the incident and to cultivate the necessary skill and power to overcome the pain. Especially, mother's disclosing process was characterized by constant restructuring of past trauma through mother's will and knowledge, acknowledging the unmodifiable past, interpreting other people's responses, and, finally, constantly interacting with sociocultural context. The study result stressed the importance of considering the whole array of difficulties and meanings experienced by mothers in the disclosing process. Social work services should provide more professional and sensitive care when mothers try to disclose the dark secret of incestuous assault.

During orthodontic treatment, formation of white spot lesions (WSLs) around brackets has long been recognized as a potential risk. This study performed to investigate effect of preventing enamel demineralization and remineralization by application of fluoride-containing orthodontic primer. Fifty extracted bovine incisors teeth were randomly allocated to 3 groups: (I) Non-preparation specimens, (II) Application of Light Bond$^{TM}$ as fluoride containing orthodontic primer, (III) Application of Transbond$^{TM}$ XT Primer as traditional orthodontic primer without fluoride. Each group is demineralized under artificial carious solution. The demineralization pattern was evaluated using a Q-ray view, Vickers hardness test and polarized light microscope. The remained primer was calculated as 35 - 50%. The highest surface microhardness was shown on Light Bond$^{TM}$ surface. There were statistically significant differences in Vickers microhardness number between adjacent areas of Light Bond$^{TM}$ and non-prepared area. There was almost no demineralization of the enamel surface under the Light Bond$^{TM}$. At the adjacent site of Light Bond$^{TM}$, the shallow caries pattern and remineralization appearance were also observed. These results suggest that the use of fluoride-containing primers may be useful for bracket attachment to reduce enamel demineralization during orthodontic treatment.

Dentinogenesis imperfecta is an inherited disorder of dentin formation, usually exhibiting an autosomal dominant mode of transmission. Type I dentinogenesis imperfecta occurs in patients afflicted with osteogenesis imperfecta. Type II dentinogenesis imperfecta is not associated with osteogenesis imperfecta. Type III dentinogenesis imperfecta (Brandywine type) occurs in a racial isolate area in the state of Maryland. In all three types, teeth of both dentitions are affected with variable clinical appearances. The teeth are opalescent with the color ranging from bluish-gray to brown to yellowish. The dentin is abnormally soft, providing inadequate functional support to the overlying enamel. Although the enamel is normal, it fractures or chips away easily, exposing the occlusal and incisal dentin. The exposed soft dentin often undergoes rapid and severe functional attrition. The teeth exhibit bulb-shaped crowns with constricted cementoenamel junctions and thin roots. The teeth will exhibit varying stages of obliteration of the coronal and root pulpal chambers. The cementum, periodontal ligament and supporting alveolar bone appear normal. The enamel is normal. The mantle dentin remains nearly normal, whereas the remaining dentin is severely dysplastic. The dentinal tubules are disoriented, irregular, widely spaced, and usually larger than normal.
