This paper is concerned with knowledge representation schemes best suited for human resource management (HRM) problem domains including human resource planing, selection, placement, compensations, performance evaluation, training and labor-management relations. In order to suggest the scheme we consider two research gods. First, we evaluate and prioritize. The knowledge representation techniques of frames rules, semantic nets and predicate logic that hove been recommended to managerial domains. The combined Analytic Hierarchy Process technique is employed to combine individual judgments effectively between two different expert groups. As a result if we are to select a single knowledge representation technique, a frame representation is best for most HRM domains and to combine frames with others is another choice. Second as a strategy for knowledge representation schemes we show some examples for each damn in terms of labeled semantic nets and two types of rules derived from the semantic nets. We propose nine knowledge components as ontologies. The labeled semantic nets con provide some benefits compared with conventional one. More clearly definea node rode information maces it easy to find the ac information. In the rule sets, the variables are the node of the semantic nets. The consistency of rules is validated by the relationship of the knowledge components.

Due to the complexities of the real-world system, a water resource management program has to deal with various types of data. It appears that management personnel who has to use the program usually suffers from the technical burdens of handling large amount of data and understanding the optimization theory when they try to interpret the results. By combining the capabilities of database technology and modeling technique with optimization procedure we can develop a reliable decision supporting tool for multi-reservoir operation planning, which yields operating schedule for each dam in a river basin. We introduce two special data handling methodology for the real world application. First, by treating dams, hydro-electric power generating facilities and demand sites as separate database tables, the proposed data handling scheme can be applied to general water resource system in Korea. Second, by assigning variable names using predetermined key words, we can save searching time for identifying the moaning of the variables, so that we can quickly save the results of the optimization run to the database.

Extensive use of antibiotics over recent decades has led to bacterial resistance against antibiotics, including gentamicin, one of the most effective aminoglycosides. The emergence of resistance is problematic for hospitals, since gentamicin is an important broad-spectrum antibiotic for the control of bacterial pathogens in the clinic. Previous study to identify gentamicin resistance genes from environmental samples have been conducted using culture-dependent screening methods. To overcome these limitations, we employed a metagenome-based culture-independent protocol to identify gentamicin resistance genes. Through functional screening of metagenome libraries derived from soil samples, a fosmid clone was selected as it conferred strong gentamicin resistance. To identify a specific functioning gene conferring gentamicin resistance from a selected fosmid clone (35-40 kb), a shot-gun library was constructed and four shot-gun clones (2-3 kb) were selected. Further characterization of these clones revealed that they contained sequences similar to that of the RNA ligase, T4 rnlA that is known as a toxin gene. The overexpression of the rnlA-like gene in Escherichia coli increased gentamicin resistance, indicating that this toxin gene modulates this trait. The results of our metagenome library analysis suggest that the rnlA-like gene may represent a new class of gentamicin resistance genes in pathogenic bacteria. In addition, we demonstrate that the soil metagenome can provide an important resource for the identification of antibiotic resistance genes, which are valuable molecular targets in efforts to overcome antibiotic resistance.

최근의 프로그램들은 그림 파일이나 오디오와 같은 대용량의 자원을 사용하는 경향이 있다. 이와 같은 대용량 자원을 사용하는 경우 그 자원의 크기가 클수록 자동 관리 시의 효율성이 더 많이 저하되며, 자원의 수가 많을수록 관리의 어려움이 증가된다. 이에 본 논문은 파일시스템의 트리 구조의 인터페이스를 자원관리 시스템에 적용하여 편의성과 효율성을 도모한 자원관리시스템을 제안한다. 이 시스템은 문자열경로 기반의 접근방식을 채택하여 높은 호환성을 가지고 있으며, 트리 구조 지원으로 높은 구조성을 도모하고, 가상 노드의 지원으로 높은 효율성을 보인다. 본 시스템은 프로세스 안에서의 자원 관리를 위해 설계되었으나, 프로세스 외부로부터의 자원제어도 지원한다.

This study reviews a family-friendly system of companies from the viewpoint of family resource management. The concept of a family-friendly system in the workplace means that the strategy 'supports the family' or 'is sensitive to the family life' and recognizes a need for balance between work and family. The suggestions proposed in this study were as follows: First, the direction of a family-friendly system must reflect the needs of the family members positively and recognize diversity. Second, it must consider efficient methods relating to the matter of the gender because a corporate culture enabling men to use childcare leave has not grown, even in family companies. Third, the directions to check the present developing process of our society and to develop the suitable way to each company must be shown. This study has proposed that the subjects must solve immediately in the future with understanding the contents and looking around the status of the enforcement at the inside and outside of the country for a family-friendly system to handle the balance between work and family in the workplace. The problems were the context of the introductions and the results of balancing between work and family no matter whether the introduction of the system by company or not.

Today, a desirable way to manage livestock manure is to activate its utilization as a resource. The production of high quality liquid fertilizer of livestock manure is very important because it increases the use of various liquid fertilizer. However, the result of mature evaluation with a maturity measuring instrument for liquid fertilizer showed that the deviation of concentration between liquid fertilizer did not bring into uniformity. The result is also making sure that quality management for liquid fertilizer is not smoothly made. Quality evaluation for compost and liquid fertilizer includes physical, biological, chemical and microbiological methods, but a chemical method is mainly being implemented due to fairness and field application. Therefore, this study figured out correlation in feces and urine through regression analysis of livestock manure and tried to create a research plan to carry out efficient quality analysis of managing livestock manure.

Korean agriculture experienced rapid changes in its production structure to respond fluctuations on external conditions, and these changes have increased the dependence between agricultural resources and negative environmental externalities from agricultural production. As a tool for managing agricultural resources and reducing negative environmental effects from agricultural production, this study employs water-energy-food nexus for integrated resource management. To show the necessity of an integrated approach, this study evaluated three policy scenarios including changes in capital interest, water capacity, and energy cost. The results show that three scenarios have unintended consequences for farmers' incomes and their use of resources. Also the unintended consequences of government policies also affected farms' vulnerability to environmental changes. In particular, the expansion of financing for the establishment of non-circulating water curtain facilities did not have a significant effect on the crop switching of farms. In addition, increasing the amount of available water through the aquifer recharge project leads to the installation of non-circulating water curtain facilities in zucchini farm. It raises dependence on groundwater in agricultural production, thereby increasing farmers' vulnerability to groundwater shortages. These results imply that the agricultural sector needs to consider the interrelationship between agricultural resources when designing or evaluating policies.

This study aims to examine the impact of accessing industrial factors in enhancing business performance with special reference to Muslim women entrepreneurs in Sri Lanka. Industrial factors are industrial resources available to Muslim women entrepreneurs in Sri Lanka and it was measured using the dimensions of resource accessibility and government and non-governmental support. A structured questionnaire was used to collect data from 260 women entrepreneurs from the Muslim community who are registered with the chamber of commerce in the three districts of the Eastern province of Sri Lanka, using a simple random sampling technique. Structural Equation Modeling with AMOS was used as the data analysis technique. The structural model showed that resource accessibility had a significant and positive relationship with business performance, whereas government and non-governmental support did not significantly influence business performance. Especially, Muslim women entrepreneurs in Sri Lanka do not show interest in getting support such as finance, training, and other necessities from government and non-government organizations as well as business development support agencies. Trade chambers and decision-making authorities may use this finding to gain insights and develop strategies to enhance the business performance of women entrepreneurs.

In cognitive radio networks (CRNs), the computational complexity of resource allocation algorithms is a significant problem that must be addressed. However, the high computational complexity of the optimal solution for tackling resource allocation in CRNs makes it inappropriate for use in practical applications. Therefore, this study proposes a power-based pricing algorithm (PPA) primarily to reduce the computational complexity in downlink CRN scenarios while restricting the interference to primary users to permissible levels. A two-stage approach reduces the computational complexity of the proposed mathematical model. Stage 1 assigns subcarriers to the CRN's users, while the utility function in Stage 2 incorporates a pricing method to provide a power algorithm with enhanced reliability. The PPA's performance is simulated and tested for orthogonal frequency-division multiplexing-based CRNs. The results confirm that the proposed algorithm's performance is close to that of the optimal algorithm, albeit with lower computational complexity of O(M log(M)).

Various types of karst topographies are found worldwide. Owing to their global distribution, karst areas have been extensively studied by scientists who investigate new discoveries by linking the characteristics of karst topographies with their own research fields. However, there have been only a few studies on karsts in the Republic of Korea, and little research exists on their hydrogeology. Fragmentary studies have been conducted on the hydrochemical characteristics of groundwater in limestone areas, the causes of high arsenic concentrations in groundwater, and the hydraulic conductivity of limestone areas. Research on hydrogeological characterization and flow mechanisms in these areas has only began recently. Identification and the proper management of available groundwater resources in karst (limestone) areas is essential as their unique geological characteristics render it difficult to construct reservoirs or dams at appropriate scales. We have reviewed prior work on karsts in the Republic of Korea to provide information that supports water resource security in the karst areas, to improve the understanding of the equitable use of water resources, and to identify the best management practices for groundwater resource resilience improvement.
