The intent of this study is to fully investigate the major issues and challenges related to characteristics of gifted children from multicultural families in Korea. The gifted students of multicultural families are currently categorized as disadvantaged gifted students, but they need to be defined more deeply and separately due to the continuous increase of multicultural families. Most culturally different gifted children have common problem such as integrating into Korean culture, often suffering from emotional problems and their parents' economic disadvantage. Due to these problems a variety of issues arise. First, culturally diverse talented students have problems due to the alienation and the lack of equal opportunity given to gifted children of multicultural families in need. Secondly, another issue is whether or not the selection of these students for a gifted and talented program is administered equally and fairly. Thirdly students and teachers may have difficulty forming relationships. Fourth, there is a dire need to address the issue of a lack of formal education policy. for these students. Fifth, the formulation of a gifted and talented program solely for multicultural students is necessary. Sixth, educating the parents of such students remains a critical challenge. Seventh, the last issue arises from a lack of research regarding the identity of multicultural gifted children in Korea. In this study, we discuss each of these issues in-depth. Additionally the future of Korean Multicultural Gifted selection, training in the field, school direction and it's implications are discussed.

The aim of this study is to explore the status and tasks of selecting, expanding, and supporting the gifted teachers to efficiently manage the gifted education. This study addresses that the ratio of applications for new teachers is lower and the current teachers are aging in primary school. In addition, it points out that the ratio of new teacher applications and teacher acquisitions compared to the number of teachers hired for middle school were lower. The gifted teachers are basic in their classes and work at regular schools, and they suffer from considerable exhaustion and a lack of time because of other gifted work. As a result of these discussions, it has shown the need for substantial improvement and supplementation such as school hours reduction or reinforcement adjustment, complete support for research society, invitation professional teachers other than current ones, and friday after school classes for the gifted teachers should be encouraged to work passionately. For professional development, if the positive perception and results of gifted education from the interactions between general education and gifted education be formed, and the education programs for gifted teachers be expanded, they will also contribute to the overall improvement in the quality of our education.

The onion moth, Acrolepiopsis sapporensis, was monitored in the farms cultivating the welsh onion, Allium fistulosum, using sex pheromone from transplantation to harvest. Two occurrence peaks were observed at early June and late July after the overwintering population. However, the population sizes were varied among different years and the cultivating environments. To effectively control A. sapporensis with microbial pesticides, different Bacillus thuringiensis strains were screened to select B. thuringiensis kurstaki (BtK). To enhance the insecticidal virulence of BtK, the culture broth of Photorhabdus temperata temperata (Ptt) was added to the BtK. This mixture of two entomopathogenic bacteria was called 'BtPlus', which was superior to BtK alone in the insecticidal virulence. The enhanced virulence was explained by the immunosuppressive activity of the secondary metabolites contained in the Ptt extract. The metabolites inhibited both cellular and humoral immune responses of A. sapporensis, resulting in the enhanced virulence of BtK. These results suggest that A. sapporensis occurs in the welsh onion fields and the resulting economic damage would be effectively prevented by BtPlus application.

There are some common and broad trends in National crisis management system around the world. This article considers that paradigm theoretically. 1) a shift from civil defense to civil protection, 2) 10 principles in sustainable National crisis management system, 3) the collaborative governance of crisis management. Some civil defense problems in National crisis management system are as follows; 1) obscurity of organizational identity through twofold function in civil defense, 2) ineffective organization in civil defense and disaster management system, 3) weakness of competencies in local government, 4) overlook of actual condition in communities and civil defense resources. This article suggests that to provide retired and active private security practitioners, retired law enforcement personnel, and retired military personnel to form a elite civil defense force and to find creative ways to address this pervasive threat which one reasonable and affordable solution would be for the government to take advantage of an existing resource.

Weed management under organic farming systems is very problematic since organic agriculture does not allow synthetic herbicides. Bioherbicide is needed to develop for weed management in organic agriculture systems. This review covers current status and perspectives of bioherbicide development for effective nonchemical weed management in organic farming systems. Bioherbicides are products of natural origin derived from living organisms, and more specifically bacteria, fungus and plants including natural metabolites for weed control. Bioherbicides derived from microorganisms or natural molecules are currently available on the pesticide markets. Devine, Lockdown (Collego), BioMal, Camperico, Organo-Sol and Opportune were derived from bacteria, Woad Warrior, Smolder, Mygogen, Chontrol Paste, Starritor and Phoma derived from fungus, and Katoun (pelargonic acid) and Beloukha were derived from plants. Corn gluten meal products and plant essential oils products are also available for nonselective weed control in organic agriculture. Organic weed management methods may be more feasible in small scale farming and high-value crops, and bioherbicides may be applied with other weed control practices in organic farming systems.

Bacteria of the genus Enterococcus are of importance in food fermentations as well as their use as probiotics in humans and livestock. However, they are also important nosocomial pathogens that cause infections. Some strains are resistant to multiple antibiotics and possess virulence factors. The role of Enterococcus species in disease has raised issues on their safety for use in foods or as probiotics. First, this review summarized the positive and negative traits of Enterococcus spp. to illustrate the controversial nature of this bacterial genus and discussed the current genomic approaches can eliminate pathogenic strains. Then, this review examined the current status of starter development for traditional food fermentations and the regulation on the approval of novel food microorganisms in Korea to point out problems in the regulation. Based on the conclusions from the studies on Enterococcus spp., we suggested the direction of safety assessment of novel food microorganisms in Korea.

The adults of Hermetia illucens collected in Korea were about the same size as those from their origin. The body part with the largest size variation was the antenna 2 followed by the head width and the abdomen width. It can be the baseline of selection of superior individuals for organic waste decomposition and compost production. In regards to the habitat, the adult Hermetia illucens were collected from 22 of the 51 localities. Although geographical characteristics such as coordinates and altitude may not affect the insects, the presence of organic matters could affect them. The distribution pattern of the insects may act as an indicator of natural recycling of organic wastes.

In this review, the compositions of the sex pheromones of 22 lepidopteran species were analyzed and briefly arranged by comparing the research results conducted in different locations worldwide. These compositions can be used as monitoring tools for pests of rice, maize, leguminous crops, perilla, and sesame in Korea. The sex pheromone compounds and those compositions of four species were successfully identified within Korean populations. The optimal compositions of sex pheromones of three other species were selected through behavioral studies using synthetic chemicals of the known pheromone compounds in laboratories and fields, without chemical identification processes in the sex pheromone compounds of Korean populations. For a few species, the roles of the minor components of the sex pheromone volatiles should be re-assessed for use in the development of optimal monitoring lures.
