In this paper, we proposes a multilevel inverter which can synthesize multi output voltage levels by adding DC voltage sources and switch components. In the proposed circuit topology, full-bride inverter determines the output polarity and the number of output voltage levels are defined by the operation of the additional switches. It can reduce the number of switch devices compared with the conventional approaches when they generate the same number of output voltage levels. To verify the validity of the proposed multilevel inverter, we present simulation and experimental results using a prototype.

Unequal distribution of shares among children during intergenerational transference of assets has been prevalent in Korea. This study intends to examine whether parental contribution, in the form of a cash gift, is differentiated between the bride's side and the bridegroom's side at marriage and by age group. This pattern may also change according to the generation. Questionnaires were equally distributed to members of three previously delineated age groups: 20' s-30' s, 40's -50's, and 60's and above who are married or have been married at least once and reside in Seoul or Gyeonggi province. A total of 700 questionnaires were analyzed using SPSS and the data were sorted by age group. The results indicate an apparent difference between the husband's side and the wife's side in providing funding for housing at marriage in that a large portion of the funding is provided by the husband's side. Among various funding sources, a cash gift from the couple's parents appears to fund the largest portion of the total cost for housing and marriage. Results show that a cash gift from the couple's parents funds a larger portion of housing expenses for younger generations, a phenomenon that becomes more severe and apparent the younger the couple is.

We examined the relationship between the extent of Facebook usage and social well-being with consideration of cyberbullying involvement using a person-oriented approach. Survey data were collected from a sample of 312 secondary students from Grades 7 and 8 in Hong Kong. Levels of cyberbullying involvement, Facebook usage and perceived social support were investigated. Participants were classified into three clusters based on the different levels of Facebook usage and cyberbullying victimization through cluster analyses (i.e., frequent Facebook user/noncyberbullied victim, frequent Facebook user/cyberbullied victim, and uninvolved). Our results showed that frequent Facebook users who are cyberbullied tend to engage in cyberbullying perpetration significantly more than the frequent Facebook users who are not cyberbullied, even when the latter reported higher Facebook usage. This result provides some support for the idea that cyberbullying victimization has additional value on top of the level of usage in explaining one's participation in cyberbullying perpetration. As expected, frequent Facebook users who were not cyberbullied reported the highest perceived social support among the three groups. What is even more interesting is the equal level of perceived social support found between the cyberbullied victims and the uninvolved. Our results suggest that, although limiting adolescents' Internet use might reduce their risks of being involved in cyberbullying, it might also take away the potential benefits they could get from interacting with the online community. Benefits of using the person-oriented approach in the study of cyberbullying are discussed.

Objective: This review consolidates the available information on the socio-economic and ecological significance of Mithun in the lives of ethnic communities in the Eastern Himalaya. Methods: Standard guidelines were followed for the review and data collection was carried out at three stages; literature search, literature screening, and literature review and analysis. Results: Records indicate a long association of Mithun with the ethnic groups. Mithun serves as a symbol of pride and local currency for barter trade in the ethnic society. Its utilities range from being used as a bride price to settling legal disputes. Several cultural festivals and local ceremonies are celebrated around this bovine. Due to its semi-wild nature, this animal also has an ecological role to conserve broad leaf sub-tropical forests. However, it remains neglected and has not received policy attention, leading to a stagnated growth. The institutions for Mithun research and development are also weak. Furthermore, the species is under threat from new diseases and habitat alteration triggered by climate change. Conclusion: Founded on the current state of knowledge, there is a need for institutional development, strengthening institutional linkages, and promoting regional cooperation among Mithun rearing countries for further research and development of this unique cattle.

Disabilities can emerge due to traumatic spinal fractures. In terms of sacrococcygeal spine, because of its unique anatomic structure with minimal movement, the possibility for it to have a disability is relatively low. In Korea, unlike most disability criteria, private insurance companies acknowledge angular deformities caused by vertebral fractures as disabilities according to their degree, so there were several cases where patients required compensation, arguing angular deformity caused by sacrococcygeal fracture, which in some cases led to legal conflicts. Except the Act Welfare of Persons with Disabilities which recognizes only severe angular deformity affecting internal organs as disability and the industrial accident disability evaluation which does not recognize coccygeal fracture as disability but rarely recognizes sacral vertebra deformity equivalent to compressive deformation, there is little or no case where angular deformity is recognized as disability. Given the impairment evaluation standards in social insurance, McBride system, American Medical Association (AMA) guides, and newly proposed standards by the Korean Academy of Medical Sciences (KAMS), the most contentious point in the general terms and conditions of private insurance is spinal deformity. To overcome controversy over disability evaluation, the private insurance sector is now applying criteria for axial skeleton to sacrococcygeal vertebrae through revision of standards. Under these circumstances, it is fair to recognize sacrococcygeal fracture as impairment in terms of the pelvis only when the fracture leaves serious deformity and neurological symptoms with clear relevancy. Though it may not be easy to develop accurate disability evaluation standards, improvement is necessary to remove any irrationalities and make the standards as objective as possible.

"Keunmeori", the grand headdress with various decorations attached to thickly braided and raised hair has been used as a bride's formal attire since the Joseon Dynasty, and in the modern period, new styles known as goegye and hyuche appeared as formal attire for civil weddings. Goegye was formed from a round wooden pillar wrapped with hair and decorated richly with ornaments; getting married with goegye meant that the wife was officially married. Hyuche was made by braiding the hair into two long plaits and decorating it with colorful fluttering hairpins and gold leaf hair ribbons. Hyuche was originally formal attire for a princess at her wedding, and it is thought to have been less frequently used in the private sector due to its higher cost than goegye. The style of goegye appears to have been influenced by the susik, the highest formal attire for a queen, and in particular, the decorations on the circular top part of the susik were presumed to have been similarly reproduced in folk weddings. Goegye changed in various aspects according to the social environment and atmosphere of the times, and was also used as formal attire for a prince's wife.

The drastic growth of transnational marriage since the mid-1990s has been a new challenge to Korea. This article aims to provide a comprehension of new ethnicity by focusing on transnational marriage migration in Korea. A steep increase of foreign brides from China and Southeast countries such as Vietnam and the Philippines can be understood in terms of globalization from below. In this context, Korean trend is similar to Taiwan and Japanese ones. But, there are also some differences between them. The inflow of foreign brides has been gradually weakened since 2005 in Korea, as Taiwan has experienced since 2003. In the ratio of foreign brides among total marriage in Korea, rural area show in average two-fold higher than urban areas. However, most foreign brides have settled down in urban areas in aspect of absolute number. Korean Chinese wives most densely concentrate in urban area, followed by Chinese wives, Nevertheless, there are significant differences among foreign brides' residential areas with their nationalities. In this point, the geography of new ethnicity with foreign brides in Korea is likely to be a multi-dimensional space.
