Many plant species are used in Malaysia in folk medicine for the treatment of cancer. This paper presents some of these species with details on other ethnopharmacological uses, the known bioactivities and some chemical constituents of each of the species given. It is normal practice in traditional medicine that one species of plant is used to treat various ailments. Thus the plant species listed are all used to treat cancer but have various other ethnophrmacological uses as well, some with few other uses and rest with many other uses. Information on bioactivities of each species resulting from tests on human and experimental animals are also given. Proven bioactivities give strength to ethnopharmacological claims on the efficacies of plant resources in the treatment of cancer and various other ailments but will but will not necessarily lead to the production of new pharmaceutical drugs. Many of the known chemical constituents of each species are given. This shows the richness and variety of chemicals containes in each of the species listed. The chemicals listed may or may not prove to be important in the pharmaceutical sciences but is an indication of what each species contatin in thrms of plant chemicals. It is a well known fact that many of the pharmaceutical prescriptions in present day use are of plant origin and semi-synthetic or fully synthetic chemicals produced using knowledge gained from studies of phytochemicals. Thus the paper presented will give useful information and also shows the richness of plant species that have high potentials for the development of anti-cancer resources from plants in Malaysia.

The article aims to elaborate on the fundamental insights of Hegel's political philosophy from a 'public freedom theory and public philosophy' perspective. The article is based on the understanding that Hegel's theory of freedom desires public freedom, and explains the contemporary meanings of the theory of freedom. The article critiques two subjects based on the interpretation of Hegel's public philosophy-the first is atomistic individualism and the other is the absolute alterity theory supported by Levinas and Derrida. In other words, through this article the author emphasizes that Hegel's public freedom theory clearly illustrates the limitations of atomistic individualism, and goes on to provide a subject theory that includes a dual/multiple theory on 'the other' that is distinct from the Levinas-Derrida approach.

One of wild diploid Solanum species, Solanum chacoense, is one of the excellent resources for potato breeding because it is resistant to several important pathogens, but the species is not sexually compatible with potato (S. tuberosum) causing the limitation of sexual hybridization between S. tuberosum and S. chacoense. Therefore, diverse traits regarding resistance from the species can be introgressed into potato via somatic hybridization. After cell fusion, the identification of fusion products is crucial with molecular markers. In this study, S. chacoense specific markers were developed by comparing the chloroplast genome (cpDNA) sequence of S. chacoense obtained by NGS (next-generation sequencing) technology with those of five other Solanum species. A full length of the cpDNA sequence is 155,532 bp and its structure is similar to other Solanum species. Phylogenetic analysis resulted that S. chacoense is most closely located with S. commersonii. Sequence alignment with cpDNA sequences of six other Solanum species identified two InDels and 37 SNPs specific sequences in S. chacoense. Based on these InDels and SNPs regions, four markers for distingushing S. chacoense from other Solanum species were developed. These results obtained in this research could help breeders select breeding lines and facilitate breeding using S. chacoense in potato breeding.

Objective: The purpose of this study was to classify early childhood educators' perfectionism types and to identify differences in teacher self-efficacy and teachers burnout according to the types of perfectionism. Methods: The participants of this study were 309 teachers working at early childhood education centers in Seoul, Gyeonggi-do, Daejeon, Se-jong, Kim-Cheon, and Hong-Sung, South Korea. Early childhood educators were surveyed regarding perfectionism, teacher self-efficacy and teacher burnout. The collected data were analyzed using K-means cluster analyses and analysis of covariance. Results: Cluster analyses with self-oriented perfectionism and other-oriented perfectionism as cluster variables resulted in three types of perfectionism among early childhood educators; 'self-other directed perfectionism(33.0%)', 'other directed perfectionism(35.0%)' and 'non perfectionism(32.0%)'. Educators with self-other directed perfectionism reported higher teacher self-efficacy and lower teacher burnout than educators with other directed perfectionism or with non perfectionism. Conclusion/Implications: Early childhood educators' perfectionism may be a significant personality trait linked to quality of education and care in real education settings.

This study investigates an association among Facebook users' upward comparison (e.g., envy), social support (e.g., favorable comments and like), and life satisfaction, putting their self-esteem as a mediating variable. For this analysis, 1,332 female and male Facebook users in Seoul and other four cities in South Korea were surveyed. Structural equation modeling including confirmative factor analysis were employed as quantitative analysis methods. Results show that Facebook users' upward comparison with other users and social support significantly impact their satisfaction mediated by their self-esteem. Specifically, when users feel envious of other users, this emotion lowers their self-esteem, and subsequently, the self-esteem reduces their satisfaction. On the other hand, sufficient social support for users positively affects their self-esteem, which leads to the increase of their satisfaction. The present study is differentiated from previous studies in that it focuses on Facebook users' emotional changes in the process of sharing massive amounts of posts and finds a stepwise relationship among their feelings, including self-esteem as a mediating variable. Additionally, this study is the first to verify a situation when Facebook users' envy of other users' posts affects the decline in their satisfaction through the mediation of their self-esteem.

This paper analyzes the formation of Tianjin dialect by investigating the immigration situation in Tianjin in history, analyzing the rhyme phenomenon of Tianjin dialect and comparing Tianjin dialect with surrounding dialects. First of all, with the need of transferring grain from the south to the north after the Ming Dynasty, the canal-centered grain transportation industry developed, and the immigrants in Tianjin naturally began to increase. In the Qing Dynasty, a large number of commercial immigrants flowed into various areas of Tianjin with the expansion of Tianjin's urban scale. This way of immigration makes Tianjin dialect preserve some dialectal features of other regions. By comparing with other Mandarin dialects, it is found that this is not only a feature of Tianjin dialect, but also a common feature in other Mandarin dialects. Therefore, we can draw a conclusion that the opinion of considering the dialect of one region is the mother dialect of Tianjin dialect because a certain phonological feature of Tianjin dialect is the same as that of other specific area is not appropriate. On the other hand, these immigrant dialects, which well reflects the characteristics of Tianjin, just show that these dialects have formed the present Tianjin dialect in the form of integration after the Ming and Qing Dynasties.

In the field of content-based image retrieval, various mathematical low-level features have been proposed to describe the perceptual content of images. Since most of the features are assumed to be independent of each other, one feature is extracted from images without any consideration of the other features. Recently proposed CCE and SCFT taking advantage of the correlation between color and texture have shown relatively good performance. In this paper, the performance of CCE, SCFT, and the traditional regular weighted comparison method are evaluated. Simulation results with natural images have shown that CCE outperforms the other methods.

After I stated the kinds of ancient embro-ideries of Shoso-in and the other places in Japan, including Silk embroidered design of a bird, Silk embroidery on a silk ground, and Buddha preaching. I searched for the possible countries they could have been made in. I found that Japan merely imported the dyes and paints from Korea, On the other hand, Korea unlike Japan, was capable of manufac-turing the embroderies from early times. The embroideries in Shoso-in and the other place, have respectivly on them the old Korean types of patterns such as flowers, lotuses, flying clouds, phoenixes, intertwined lions, houses, ghost masks, fairies and turtles, seen often on the titles of Silla.

The CANDU nuclear-electric generating system, developed in Canada beginning in about 1950, has reached full maturity with 22 units operating in other countries, and 13 units under construction, as shown in Table 1. Production and economic performance of modern CANDU units is competitive with other nuclear generating stations in the world. The safety record of these plants is excellent; their level of safety protection against severe accidents is at least equal to that of other commercial designs.
