Tendencies such as the increasing spread of market globalization, new technological developments, the reduction of product life cycles and aggressive competition, are generating high levels of environmental changes and uncertainty for organizations of all types. these circumstances require rapid responses through adaptation of organizational attitudes and capabilities, which lead to innovative management approaches and organizational methods. Human resource management researchers have struggled to elaborate the underlying mechanism explaining how human resource systems relate to organizational performance after universalistic perspectives were supported by a majority of studies investigating the positive relationship between human resource management system and firm performance. To fill the void, hypotheses in this study predicted human resource flexibility that would mediate the relationship between human resource management system and firm performance. The research model among the variables in this study was as follows: These theoretical models were tested with a sample of 138 firms in Korea. The analysis of data was undertaken by using AMOS. The Summary of the verification results is follows: Firstly, most of human resource management system and human resource flexibility had positive effects on human resource performance Secondly, most of human resource management system and human resource flexibility had positive effects on firm's financial performance Thirdly, human resource flexibility had mediated the relationship between human resource management system and firm performance The results of the present research may be demonstrated that organizations or managers could achieve a high level of management practices that lead to firm performance by enabling human resource to be flexible through high performance human resource management system.

Partial mitochondrial 16S rDNA and COI gene were amplified using PCR and sequenced for four species of oysters in Korea. Phylogenetic relationships among them were inferred from their aligned sequences by neighbor-joining method. The sequence comparison data of two mitochondrial genes showed that the genetic distinction between two oyster genera (Crassostreo and Ostrea) was obvious. Phylogenetic analysis based on the nucleotide sequences and A+T percentage of two genes indicates that C. gigas and C. nippona strongly formed a sister group and then C. ariakensis was clustered with the clade although that based on amino acid sequences of COI gene by neighbor-joining method represented different phylogenetic tree.

Colletotrichum species are important fungal pathogens that cause great damages on various host plant species worldwide. In Korea, Colletotrichum species cause massive economic losses on apple, peach, grape, and especially, sweet persimon productions. In the past, identification of the pathogen and the studies on the genetic relationships among the pathogenic isolates were mainly based on morphology, cultural characteristics, and the difference in pathogenicity. However, in recent years, these traditional methods have been replaced with molecular methods including AFLP. AFLP method with the merits of both RAPD and RFLP has been widely used for the genetic relationship studies of various organisms. Therefore, in this study, AFLP method was employed for the studies of genetic relationships among the different isolates of Colletotrichum species collected from various parts of sothern Korea. As a result, two specific band pattern groups were observed among different isolates of Colletotrichum species.

This study examined the relationships among smartphone addiction, parenting attitudes and resilience to identify the relevant factors affecting smartphone addiction. Data were collected from a total of 220 middle school students responding to questionnaires in G city and analyzed using descriptive statistics, independent t-test, ANOVA, $Scheff{\acute{e}}$ test, Pearson coefficient correlation, and multiple regression. The results showed that the parenting attitude and resilience were negatively correlated with smartphone addiction. The significant factors affecting smartphone addiction were gender, the time of smartphone usage, parenting attitudes, and resilience. These variables explained 21.9% of smartphone addiction and the highest factor was the parenting attitudes, followed by gender, time of smartphone usage, and resilience. This study indicated that it is important to develop a program to ensure adolescents positively perceive parenting attitudes and increase their resilience to decrease the incidence of smartphone addiction.

The trnL-F region islocated in the large single-copy region of the chloroplast genome. It consists of the trnL gene, the trnL intron, and the trnL-F IGS. Molecular evolution and phylogenetic relationships in Korean Thalictrum L. were investigated using data from the cpDNA trnL-F region. Bayesian and parsimony analyses of the data set with the gap characteristics recovered well-resolved trees that are topologically similar, with clades supported by some indels evolution. Indel events of cpDNA trnL-F in Korean Thalictrum were interpreted as phylogenetically informative characteristics. Sect. Physocarpum (excluding T. osmorhizoides) was an early-diverging group with in the genus and the remaining section formed strongly supported clades. Korean Thalictrum has various evolutionary patterns, such as the spatial distribution of the nucleotide diversity and transversion-type base substitutions in the trnL-F region.

The morphological relationship between Drosophila melanogaster and D. simulans, and their hybrids were investigated using comparisons of internal reproductive organs. male sex comb tooth number and male genital discs. InterspecIfic hybrids of all crosses were completely sterile, and had rudImentary gonads. Dysgenic ovaries and testes were morphologically similar to those of gonadal dysgenesis stenlity associated with the PM system in D. melal1ogaster. The mean number of sex comb tooth in D. melrmogaster, D. simulans and their male hybrids were 10.73, 8.35 and 9.97, respectively. The general aspects of the genital disc of the malo hybrid were a mosaic-like structure between D. melanogaster and D. simulans.

A systematic review for Korean Liliopsida was carried out with rbcL and atpB sequence data. Congruent phylogenetic trees were obtained from two different data sets. Korean Liliopsida consists of the three orders, Asparagales, Liliales, and Dioscoreales sensu Dahlgren et al. Members of Dioscoreales were used as an outgroup for inferring relationships among Asparagales and Liliales in the molecular studies. Iridaceae showed close relationship to Asparagales both in the rbcL and atpB sequence trees rather than to Liliales. Family Nartheciaceae (previously included within Melanthiaceae s. lat.) appeared as a paraphyletic assemblage basal within Liliales, but did not show relationships to other orders. Genera of Ruscaceae (previously Convallariaceae) like Disporum, Clintonia, and Streptopus had to be transferred to Colchicaceae, Liliaceae, and Calochortaceae, respectively. A revised list of families for Korean members of Liliopsida is suggested.

This study aims to define the phylogenetic relationship within Korean section sabina and find molecular markers which resolve the phylogenetic relationship in genus Juniperus and section sabina. cpDNA matK and psbA-trnH were used as molecular markers. The combined analyses of two genes suggested that section sabina was a clade supported by 100% BP. The relationships of [J. chinensis var. sargentii+J. davurica] clade and [J. chinensis var. chinensis+J. chinensis var. procumbens+J. chinensis var. horizontalis] clade were supported by 91% BP and 100% BP, respectively. Thus, the classification of Korean section sabina would be appropriate at follows, (1) J. chinensis var. sargentii+J. davurica, and (2) J. chinensis var. chinensis+J. chinensis var. procumbens According to the results of separate analyses, matK seems to work better resolving power to clarify the phylogenetic ambiguity in Juniperus and section sabina than psbA-trnH.
