Investigations on seismic performance of eccentrically braced frames equipped with dual vertical links have received little attention. Therefore, the main goal of this paper is to describe design steps for such frames and evaluate nonlinear performance of this system according to the reliability analysis. In this study, four and eight story frame structures are analyzed and the response modification factors for different intensity and damage levels are derived in a matrix form based on a new approach. According to the obtained results, the system has high ductility and acceptable seismic performance. Moreover, it is concluded that using response modification factor equal to 8 in the design of system provides desirable seismic reliability under the design and maximum probable hazard levels. Due to desirable performance and significant advantages of the dual vertical links, this system can be used as a main lateral load bearing system, in addition to its application for rehabilitation of damaged structures.

In the present study, a single cylinder four stroke dual fuel diesel engine was tested to investigate the performance and emission characteristics of various test fuels. The engine was tested in dual fuel mode using diesel and Karanja biodiesel blends as pilot fuel along with Natural gas as primary fuel with a constant gas flow rate under different loading conditions. From the experimentation it was found that smoke opacity and oxides of nitrogen (NOx) are at low level for all the prepared test fuels in dual fuel mode but the emissions of carbon monoxide (CO), carbon dioxide ($CO_2$) and hydrocarbon (HC) were found higher. In comparison to diesel fuel, by increasing the blend percentage different emission parameters are found to be reduced. At different loading conditions all the test fuels show poor performance in dual fuel mode of operation when compared with single mode of operation with diesel and biodiesel. With increase in gas flow rates, except (NOx) and smoke emissions, the other emission parameters like CO, HC and $CO_2$ values increased for all test fuels. Again, all blended fuels showed lower performance compared to diesel. The maximum pilot fuel savings for diesel was found decreasing with the increase in karanja biodiesel. From the present work it may be concluded that Karanja biodiesel with Natural gas in dual mode can be can used as promising alternative for diesel with some required engine modifications and further research must be carried out to minimize the emissions of CO, HC and $CO_2$.

The main objective of this study was to examine the effects of family-friendly culture in various organizations in the private sectors on employee self-reported work-family balance and qualities of lives. It also attempted to clarify whether employee perceived work-family culture would vary according to size and type of organization, gender, and dual career partnership. The data came from 365 married full-time workers employed in a wide variety of organizations located in Seoul and GyeongGi-Do. The major findings of this study were as follows: Work-family culture was perceived more family-friendly in large-sized organizations and consumer industries. Female employees and workers in dual-career partnerships perceived the work-family culture of their organizations less family-friendly. The hierarchical multiple regression analyses revealed that firm size, supervisory support for employees' family activities, and the perception of negative career development opportunities as a consequence of utilizing family-friendly policies significantly predicted employees' work-family balance and qualities of lives, while organizational time demands having no significant effects on them. The implications of study results were discussed.

This paper proposes to increase the node energy efficiency, which rapidly drops during the transmission of L-TEEN (Layered Threshold sensitive Energy Efficient sensor Network protocol), using the method of DL-TEEN (Dual-hop Layered TEEN). By introducing dual-hop method in the data transmission, the proposed single-hop method for short-range transmission and multi-hop transmission method between the cluster heads for remote transmission was introduce. By introducing a partial multi-hop method in the data transmission, a single-hop method for short range transmission method between the cluster heads for remote transmission was introduces. In the proposed DL-TEEN, the energy consumption of cluster head for remote transmission reduces and increases the energy efficiency of sensor node by reducing the transmission distance and simplifying the transmission routine for short-range transmission. As compared the general L-TEEN, it was adapted to a wider sensor field.

A phase variation has been reported in an entomopathogenic bacterium, Xenorhabdus nematophila. Compared with a wild-type primary form, a secondary form usually loses several physiological and biochemical characters. This study showed that the phase variation of X. nematophila caused a significant alteration in its immunosuppressive activity and subsequent entomopathogenicity. A secondary form of X. nematophila was detected in laboratory colonies and exhibited significant differences in dye absorption and entomopathogenicity. In addition, the secondary form was different in its production of eicosanoid-biosynthesis inhibitors (EBIs) compared with the primary form of X. nematophila. Production of oxindole and p-hydroxypropionic acid was significantly reduced in the culture broth of the secondary form of X. nematophila. The reduced EBI production resulted in significant suppression in the inhibitory effects on cellular nodule formation and phenoloxidase activity. Culture broth of the primary form of X. nematophila enhanced the pathogenicity of Bacillus thuringiensis ( Bt) significantly more than the culture broth of the secondary form. Furthermore, this study developed a highly efficient "Dual Bt-Plus: to control both lepidopteran insect pests Plutella xylostella and Spodoptera exigua, by mixing two effective Bt strains along with the addition of potent bacterial metabolites or 100-fold concentrated X. nematophila culture broth.

This research is to reveal an aspect of costume culture and a phase of the cloths in the relationship of the Chosun dynasty, by considering the exported goods from the Chosun dynasty of the trading goods derived by the trade diplomacy between the two countries in the Chosun dynasty-Japan relationship in the 15th and 16th. The research findings, by analyzing various literatures and related documents, follow. The research results are as follow. The exchange was the form of presenting a return present in return for a tribute to the Chosun dynasty from the Japanese envoy, which has a polycentric characteristic. Pusanpo, Naipo, and Yumpo were designated as the open ports, which played a pivotal role in the Korea-Japan exchange. The imported goods were somok, peppers, drug-stuffs, gold, bronze, sulfur, etc. The exported goods were books and cloths, such as hemp cloths, cotton cloths, silk, etc. The majority of exported goods was cloths, particularly cotton cloths. Meanwhile, in the 15th and the 16th century, with expanding of active trade towards Japan, the amount of export increased rapidly. As a result of the increase of exporting cotton cloths, the raw cottons production was increased and cotton cloth manufacturing was developed. However, it also expanded a dual structure of cotton cloths between the cotton cloths for exports and the cotton cloths for domestic markets. This dual structure of cotton cloth was lead to the deterioration of cotton cloths and had an effect on the price increases of domestic markets.
