This study aims to examine both the theoretical framework and practical method for the building a subject-oriented collection of information resources form Internet. Through the study, a few conclusions as well as a suggestion were derived. 1. Conclusions : (1) The continuous learning and studying by the librarians working in the information society is required in order that they could have a broader recognition of the existence of various resources from Internet by subject, and that they could be armed with a greater ability to evaluate for the information filtering. (2) The use of a subject directory to collect needed information resources form Internet revealed the necessity for going through many steps linked by hierarchical indexes till arriving at the desired information, and accordingly the great time was needed to conduct the work. (3) In case of using various search engines, since the output of the relevant information largely depends on the adequate defining of the topic, the right selection of search terms and the accurate methods of inputting the keywords, systematic organization of the resources is not simple and easy. The classifying work of collected resources for the topic into the broader categories differs from that of the resources form other topics, for example, psychology, because of the idiosyncrasy of the contents of the each topic. (4) As one method to provide more revolutionary value-added service using Internet, it is necessary for the librarians to learn the skills to build the Web resource pages of subject-oriented collection of information resources from Internet on the specific subject. 2. A suggestion : Since the study did not complete the collection and organization of the information resources from the Internet on this topic, the remaining research and task should be the thorough collection of resources and the building the Web resource pages consisting of interconnecting links of indexes by spending greater time.

This study aims at developing and empirically testing a comprehensive model of organizational justice derived from the prior empirical studies on organizational justice. The study seeks to understand the antecedents to and the consequences are addressed. The first question is what characteristics of the HRM systems determine the levels of perceived distributive and procedural justice. Hypotheses are derived from the two prominent theoretical models, i.e., the self-interests model (SIM) and the group value model (GVM). Those factors include neutrality, consistency, accuracy. ethicality. credibility. and reciprocity in the processes of making HRM decisions. All nine factors suggested by the two models aye adopted for this study as major determinants of both distributive and procedural justice. The second question of this study is related to the moderating effects of individual differences on the relationship between the SIM and GVM variables and perceived distributive and procedural justice in organizational contexts. The final research question deals with the consequences of perceived organizational justice. specifically job - related altitudes and organizational commitment. Job-related attitudes in this study refer to job satisfaction, job motivation, and job involvement, i.e., the willingness to make contributions. identification with organization, and intent to stay. In examining the consequences of perceived organizational justice, the study focuses on the interaction effects of procedural and distributive justice on the above nine outcome variables. The results show that both SIM and GVM variables significantly influence distributive and procedural justice. However, hierarchical regression analyses reveal that the GVM variables except more influence has been focused on the consequences of perceived distributive justice with regard to outcomes provided by the organization.

The three-dimensional organization of chromatin and its time-dependent changes greatly affect virtually every cellular function, especially DNA replication, genome maintenance, transcription regulation, and cell differentiation. Sequencing-based techniques such as ChIP-seq, ATAC-seq, and Hi-C provide abundant information on how genomic elements are coupled with regulatory proteins and functionally organized into hierarchical domains through their interactions. However, visualizing the time-dependent changes of such organization in individual cells remains challenging. Recent developments of CRISPR systems for site-specific fluorescent labeling of genomic loci have provided promising strategies for visualizing chromatin dynamics in live cells. However, there are several limiting factors, including background signals, off-target binding of CRISPR, and rapid photobleaching of the fluorophores, requiring a large number of target-bound CRISPR complexes to reliably distinguish the target-specific foci from the background. Various modifications have been engineered into the CRISPR system to enhance the signal-to-background ratio and signal longevity to detect target foci more reliably and efficiently, and to reduce the required target size. In this review, we comprehensively compare the performances of recently developed CRISPR designs for improved visualization of genomic loci in terms of the reliability of target detection, the ability to detect small repeat loci, and the allowed time of live tracking. Longer observation of genomic loci allows the detailed identification of the dynamic characteristics of chromatin. The diffusion properties of chromatin found in recent studies are reviewed, which provide suggestions for the underlying biological processes.

Asian populations contain a variety of ethnic groups that have ethnically specific genetic differences. Ethnic variants may be highly relevant in disease and human differentiation studies. Here, we identified ethnically specific variants and then investigated their distribution across Asian ethnic groups. We obtained 58,960 Pan-Asian single nucleotide polymorphisms of 1,953 individuals from 72 ethnic groups of 11 Asian countries. We selected 9,306 ethnic variant single nucleotide polymorphisms (ESNPs) and 5,167 ethnic variant copy number polymorphisms (ECNPs) using the nearest shrunken centroid method. We analyzed ESNPs and ECNPs in 3 hierarchical levels: superpopulation, subpopulation, and ethnic population. We also identified ESNP- and ECNP-related genes and their features. This study represents the first attempt to identify Asian ESNP and ECNP markers, which can be used to identify genetic differences and predict disease susceptibility and drug effectiveness in Asian ethnic populations.

A study on how fire officer's job satisfaction factors influence space satisfaction rates. This article will conduct regression analysis for the study on these three problems. 'What are the factors of fire officer's job satisfaction?', 'Does space satisfaction rates influence job satisfaction rates?', 'Which job satisfaction factor influence space satisfaction rate?' Therefore, variables were set based on the prior study, and before regression analysis was conducted, variables were purified through analysis on primary factor and reliability analysis, and hypothesis test was done via variable calculation. According to the prior study, factors that influence job satisfaction rates are as following; self-regulation of tasks, ethics and responsibility level, relationship with colleagues, job identity. And regression analysis showed that space satisfaction rates do not influence job satisfaction rates. The writer thinks that it's showing that Korean fire officers tend to prioritize colleague relationship and job identity over space improvements. And the factor that influence job satisfaction rates turned out to be the self-regulation of tasks, and the writer estimates that it's reflecting the hierarchical organization culture of current Korean fire officers. Therefore, future Korean fire station design plans need to consider a space plan that provides fire officer's private self-regulation of tasks.

Today's health care environment is rapidly changing and nurse administrators' leadership styles need to identify in nursing organization to achieve organizational objectives. By Bass(1985), transformational leadership stimulates the subordinates to be creative and achieve organizational objectives and is related to job satisfaction, job involvement, productivity, and organizational commitment. Transformational leadership process consists of charisma, intellectual stimulation, individual consideration. The purpose of this study was to identify the effect of transformational leadership and personal characteries on nurses' job involvement. The subjects for this study consisted of 594 nurses from 8 University Hospitals and General Hospitals. The data were collected by personal characteristics scale, transformational leadership scale, and job involvement scale. The factor analysis, Cronbach's alpha analysis, Pearson correlation analysis, multiple regression analysis and hierarchical multiple regression analysis were used for the statistical method. The results of this study were found that (1) charisma dimension of transformational leadership has positive influence on nurses' job involvement ; but another two dimensions (intellectual stimulation and individualized consideration) did not showed significant effect on job involvement (2) nurses' personal characteristic (internal locus of control) moderated the effect of transformational leadership on job involvement.
