The purpose this study was to analyze the factors related to the disposal behavior of college students in recycling resources. Recycling resources were classified into four categories: paper, glass, cans and plastic. The data used this study were collected through questionnaire on 420 college students living in Jeju island. The data were analyzed by using SPSS WIN program and the methods of frequency, average, standard deviation, percentage, internal consistency method, t-test, one-way ANOVA, and Scheffe's multiple range tests. The study results can be summarized as follows. Disposal behavior of paper was influenced by pocket money, of glass by sex and housing type, and of cans by housing type. Mother's education level was related to the disposal behavior of college students in recycling resources. In addition, the results showed that environment-friendly conscious and purchasing behaviors affected the disposal behavior of college students in recycling the resources of paper, glass, cans and plastic. The environment-friendly consciousness of college students was the most influential factor in the disposal behavior in recycling resources.

This study investigated the perception of upcycling for sensitive university students in regards to fashion trends. It was conducted through questionnaires delivered to male and female college students who majored in clothing related subjects from June 2012 to June 2013 in Gwangju. The contents for this research are general details, seriousness of environmental resources, awareness of upcycle, and purchasing intention for upcycling products. Most of the respondents said that recycling of resources is absolutely necessary due to the impact of environmental pollution and the consumption of resources. On the contrary, the experience of the respondents which purchased recycling products was low. The awareness of also was low, upcycling, internal upcycling brands and internal consumption groups, however, the decisions for subsequent purchases were positive. The reasons for the unsatisfactory of upcycling of products were due to quality and price. The reaction for many upcycle goods had the best question response rate in daily supplies part; subsequently, this study suggested 3 items, apparel products, fashion accessories, and daily supplies. In addition, a group which contains people who expend more for clothing had a lower awareness of upcycle and purchasing intention than other groups that contained some people who expend less. The results of the study can be used in data that recognize the necessary of upcycle education for university students, and develop educational programs. It can also encourage the purchase of upcycle products that reduce the consumption of resources.

This research was carried out to develop the Hanji(Korean paper) sludge·wood particle composite utilizing the waste sludges occurring from the making process of Hanji(Korean paper). At the research, four mixing ratios of white or black sludge to wood particle(10:90, 20:80, 30:70 and 40:60), three types of the resin adhesives(PMDI, urea and phenol resin) and three levels of the densities(0.60, 0.75 and 0.90) were designed to investigate the mechanical properties of Hanji(Korean paper) sludge·wood particle composite. In the white and black sludge·wood particle composites, bending properties(MOR, MOE) showed the decreasing tendency according to the increase of sludge additive, but it was clearly increased with the increase of specific gravity. Also tensile strength had the same tendency as in these bending properties. The internal bond strength of white sludge·wood particle composite had no tendency, but that of black sludge·wood particle composite was decreased as an increase of Hanji sludge additive.

Objectives : Bupleuri Radix (Siho) is prescribed as the root of different Bupleurum species on the pharmarcopoeia in Korea and China. Moreover, other species and varieties of the genus Bupleurum have been also distributed on the herbal market as Bupleuri Radix. However, due to the morphological similarity and frequent occurrence of intermediate forms, the correct identification of this radix is very difficult. To develop a reliable method for correct identification and improving the quality standards of official Bupleuri Radix, we analyzed sequences of the ribosomal RNA gene and internal transcribed spacer (rDNA-ITS) region. Methods : PCR amplification of rDNA-ITS region was performed using ITS1 and ITS4 primer from 6 Bupleurum species and 1 variety, B. falcatum L. (Siho), an improved breed of B. falcatum L. (Samdo-Siho), B. chinense DC. (Buk-Siho), B. scorzonerifolium Willd. (Nam-Siho), B. longiadiatum Turcz. (Gae-Siho), B. euphorbiodes Nakai (Deungdae-Siho) and B. latissimum Nakai (Seom-Siho), and nucleotide sequence was determined after sub-cloning into the pGEM-Teasy vector. Authentic marker nucleotides were estimated by the analysis of ClastalW using entire rDNA-ITS sequence of three samples per species. Results : In comparative analysis of the rDNA-ITS sequences, we found specific nucleotides to distinguish Korean (B. falcatum L. and its variety) and Chinese official species (B. chinense DC. and B. scorzonerifolium Willd.) from others at positions 411 and 447, and positions 89, 101, 415 and 599, respectively. Futhermore, we also found nucleotide indels (insertion and/or deletion) and substitutions to identify each of different Bupleurum species, 2 positions for B. falcatum L. and its variety, 6 positions for B. chinense DC., 49 positions for B. scorzonerifolium Willd., 8 positions for B. euphorbioides Nakai, 7 positions for B. longiradiatum Nakai and 9 positions for B. latissimum Nakai. These sequence differences at corresponding positions are avaliable nucleotide markers to determine the botanical origins of Bupleuri Radix. Moreover, we confirmed the phylogenetic relationship of B. latissimum Nakai, a Korean endemic speices, among Bupleurum species based on the rDNA-ITS sequence. Conclusions : These marker nucleotides would be useful to identify the official herbal medicines by the providing of definitive information that can identify each plant species and distinguish it from unauthentic adulterant Bupleurum species.

Taxonomy of umbelliferous taxa Heracleum moellendorffii complex has been unclear in their species delimitation in the far-eastern Asian regions. In both Korea and China Heracleum moellendorffii was adopted for their description while H. sphondylium was chosen to describe Japanese Heracleum. From Genbank accessions, taxa collected from Kamtchatka and Promorskiy, Russia were defined as H. maximum, endemic taxon to North America. In this study, we reviewed the taxonomy of Heracleum moellendorffii complex in Korea and neighboring countries on the basis of molecular phylogenies derived from sequences of nuclear ribosomal DNA internal transcribed spacer (ITS) regions. From three Korean accessions of Heracleum investigated in this study, two types of ITS sequences were obtained; two accessions were related to Chinese H. moellendorffii var. moellendorffii and North American H. maximum without forming a clade while the other one was identical to accession from H. maximum from Primorskiy, Russia. In the other hand, Japanese H. moellendorffii (=H. sphondylium ssp. sphondylium var. nipponicum in the flora of Japan) was closely related to H. maximum accessions from Korea and Russia, not nested within the clade comprising several subspecies of H. sphondylium. In order to delimit species boundaries among putatively closely related Heracleum species in fareastern Asian countries, more samples and much more rapidly evolved DNA regions must be investigated with interpretation of morphological and anatomical features.

Herbal plants or traditional Oriental medicine have been considered as a potential resource of new drug development worldwide. However, traditional Korean medicine has given little effort to the field of new drug development. This study reports on a plant-derived hepatotherapeutic drug, silymarin, which has been popularly used in many countries. It was discovered as an active compound from Silybum marianum (milk thistle) which has been known as a medicinal plant having hepatoprotective properties in both European and Asian countries. While it has been used as an herbal prescription in Asia, its active compounds or scientific mechanisms were intensively studied in Europe. Currently, silymarin is one of the most powerful herbal extracts in the world, and its usage is being expanded to many other medical purposes. This report would be helpful for providing an informative example of herbal-derived drug development to Oriental doctors or scientists in the Oriental medicinal field.
