  • Strategic bundling of Human Resource Management (HRM) practices among themselves works together as an entire HRM system rather than individual HRM practices to achieve organizational objectives. The bundles of HR practices support the effectiveness of one another assuming the effectiveness of any practice depends on other practices in place. It is said that the greater the total degree of bundling among the various components of HRM policies and practices, the more will be the organizational outcomes. Realizing these facts, this study aimed to explore the level of strategic bundling and examined the impact of such bundling on organizational performance to the publicly listed companies of Nepal. This empirical study is based on description and exploratory design for which data collected through the questionnaire based on 5-point liker scale. Total population of the study at the time of data collection are 234 organizations publicly listed in Stock Exchange of Nepal. Questionnaire is distributed to all organizations listed, response received from 105 organizations, as a unit of analysis, which is fairly good response. The study of strategic bundling of HRM practices perhaps the first study in Nepal, found that only 32 percent organizations have followed high bundling HR practices and these high bundling organizations are significantly different with low bundling organizations. Business organizations are trying to practice being close association of HRM policies and practices within them except labor relation with employee participation and business strategies. Supporting to the international literature, strategic bundling of HRM practices among themselves shows statistically significant effects on quality of product or services, labor productivity, financial performance, employee satisfaction, rate of innovation, employee commitment and market share.

  • Objectives: This study was conducted to characterize the impact of cognitive function and oral health status on mastication in senior citizens, ${\geq}65$ years of age, using senior centers in the city of Wonju, South Korea. Methods: A cross-sectional study consisting of a simple oral examination and survey questionnaires was performed in 154 individuals. General characteristics, subjective masticatory function, objective masticatory function, cognitive function, and oral health status were collected as variables. Correlation and multiple linear regression analyses were conducted. A p-value of <0.05 was considered to be statistically significant. Results: The subjective masticatory function was scored using the 5-point Likert scale. When subjective masticatory function was analyzed in groups according to cognitive function, the mean subjective masticatory function scores were 4.31, 4.09, and 3.29 in the normal group (cognitive score of ${\geq}16$), suspected dementia group (cognitive score of 1215), and mild dementia group (cognitive score of ${\leq}11$), respectively. Thus, subjective masticatory function decreased along with decreasing cognitive function. When cognitive function, subjective masticatory function, and objective masticatory function were compared with indicators of oral health status (number of functional teeth, oral dryness), subjective masticatory function exhibited a significant positive correlation with objective masticatory function (r=0.635, p<0.01), cognitive function (r=0.292, p<0.01), and total number of functional teeth, including prosthetic appliances (dentures) (r=0.305, p<0.01). According to the regression analysis, age, sex, number of functional teeth, and cognitive function affected subjective masticatory function. Conclusions: The results of this study revealed that age, sex, number of functional teeth, and cognitive function affected subjective masticatory function, whereas oral dryness did not. Therefore, dental professionals must consider subjective masticatory function when providing oral care in senior patients with low cognitive function.

  • In the present article, silica nanoparticles (SNPs) were exploited to improve the tribological and mechanical properties of vinyl ester/glass fiber composites. To the best of our knowledge, there hasn't been any prior study on the wear properties of glass fiber reinforced vinyl ester SiO2 nanocomposites. The wear resistance is a critical concern in many industries which needs to be managed effectively to reduce high costs. To examine the influence of SNPs on the mechanical properties, seven different weight percentages of vinyl ester/nano-silica composites were initially fabricated. Afterward, based on the tensile testing results of the silica nanocomposites, four wt% of SNPs were selected to fabricate a ternary composite composed of vinyl ester/glass fiber/nano-silica using vacuum-assisted resin transfer molding. At the next stage, the tensile, three-point flexural, Charpy impact, and pin-on-disk wear tests were performed on the ternary composites. The fractured surfaces were analyzed by scanning electron microscopy (SEM) images after conducting previous tests. The most important and interesting result of this study was the development of a nanocomposite that exhibited a 52.2% decrease in the mean coefficient of friction (COF) by augmenting the SNPs, which is beneficial for the fabrication/repair of composite/steel energy pipelines as well as hydraulic and pneumatic pipe systems conveying abrasive materials. Moreover, the weight loss due to wearing the ternary composite containing one wt% of SNPs was significantly reduced by 70%. Such enhanced property of the fabricated nanocomposite may also be an important design factor for marine structures, bridges, and transportation of wind turbine blades.

  • Late blight, caused by the hemibiotrophic oomycete pathogen Phytophthora infestans, has been the most important disease limiting potato production worldwide. P. infestans undergo major population shifts in agricultural systems via the successive emergence and migration of asexual lineages. The phenotypic and genotypic bases of these selective sweeps are largely unknown but management strategies need to adapt to reflect the changing pathogen population. Here, we used molecular markers to divide the 86 South Korea isolates into six clonal lineages: KR_1_A1, KR_2_A2, SIB-1, US-11, SIB-1 like, and KR-2 like. We documented the emergence of a new lineage, termed SIB-1 like, and KR-2 like, and their rapid replacement of other lineages to exceed 35% of the pathogen population across South Korea. Genome analyses of the Korean P. infestans populations revealed extensive genetic polymorphism, particularly in effector genes. Importantly, SIB-1 like isolates carry an intact Avr8 effector gene that triggers resistance in potato carrying the corresponding R immune receptor gene R8 cloned from Solarium demissum. These findings point toward a strategy for deploying genetic resistance to mitigate the impact of the SIB-1 like lineage and illustrate how pathogen population monitoring, combined with genome analysis, informs the management of devastating disease epidemics. Further study is being done on pathogenicity of the SIB-1 like isolates on cultivated potatoes and changes in expression patterns of disease effector genes within the SIB-1 like isolates

  • Textile reinforced concrete (TRC) has gained attention as a viable alternative to conventional reinforced concrete due to its improved mechanical properties and design adaptability. Despite significant research into the mechanical properties of TRC, studies regarding the flexural effect of pre-stretching with different numbers of textile reinforcements are currently limited. Therefore, this research focuses on assessing the flexural characteristics of TRC panels with the incorporation of mesh pre-stretching. Additionally, the study compares the flexural behaviour between alkali-resistant (AR) glass fibre TRC and carbon fibre TRC. A three-point bending test was conducted to assess the flexural behaviour of TRC, investigating the impact of the number of textile layers and the application of pre-stretching on flexural strength and post-cracking stiffness. The findings, exhibited by the flexural stress vs. displacement curve, indicate that applying pre-stretching to carbon fibre TRC effectively increases the flexural strength of carbon textiles and enhances post-cracking stiffness. Moreover, the greater the number of carbon textiles, the higher the flexural stress of the specimens, provided the textiles are placed in the tensile zone. Nevertheless, when comparing carbon fibre TRC with AR glass fibre TRC, it is found that the increase in flexural strength is more significant for carbon fibre TRC. Overall, applying pre-stretching to carbon fibre significantly improves the TRC's flexural performance, specifically during the post-cracking stage and in crack distribution. Furthermore, due to the higher elastic modulus and tensile strength of carbon fibre, TRC reinforced with carbon textiles shows greater flexural strength and ductility compared to AR glass fibre TRC.

  • The present waste problems require a change of thinking with regard to conventional economics. It has been generally believed that competitive markets maximize social welfare. But, the other hand, a few economists argue that "the competitive markets cannot always be relied on to provide all goods in the efficient amount." One of the best examples of the latter contention is the environmental problem. What is the basic thinking of the conventional economics that causes this problems \ulcorner What is the present problem that requires the change of conventional economic thinking \ulcorner The environmental problem result from the conventional economic thinking such as pursuing the limitless of the Gross National Product(GNP), believing the increasing returns in economics of scale and the efficiency of competitive market. This economic principles, howe- ver, does not apply currently to public goods, especially environmental amenity and natural resource because the price of markets does not reflect the natural goods of services. We call this eternality. Externalizes are no considered by either buyers or sellers of goods of which production or use results in an eternality. This leads to market failure are causes an waste problem in the economic activities. Today, it is almost impossible to say in a word what the solution for waste problems is because they are by-products complicated and entangled human activities. In this paper, I have introduced the causes of environmental problems only from the economic point of view. I have also described the needs of conversion of conventional economic thinking. Firstly, sustainable development, maintaining the natural resources, should be the basis of the economic growth rather that pursuing the limitless growth of GNP. Secondly, an appropriate scale of human's production activity should be taken into account to reduce the impact to the natural environment. Thirdly, internalization of eternality is asked to correct the market failure. This requires the public policy such as imposing a talsubsidy, assigning a property right or implement a more detailed environmental quality standard through, because use of the natural resources can be. allocated optimally by the intervention of government or social associations.

  • Recently a fuel oil of the diesel engine in the ship is being changed with low quality as the oil price is higher more and more. Therefore the wear and corrosion in all parts of the engine like cylinder liner ring groove of piston crown, spindle and seat ring of exhaust valve are increased with using of heavy oil of low quality In particular the degree of wear and corrosion in between valve spindle and seat ring are more serious compared to the other parts of the engine due to operating in severe environment such as the high temperature of exhaust gas and repeating impact. Thus the repair weld to the valve spindle and seat ring is a unique method to prolong the life of the exhaust valve in an economical point of view In this study. corrosion property of both weld metal zone and base metal was investigated with some electrochemical methods such as measurement of corrosion potential, cathodic and anodic polarization curves, cyclic voltammogram and polarization resistance etc. in 5% $H_2SO_4$ solution. in the case of being welded with some welding methods and welding materials to the exhaust valve specimen as the base metal. In all cases. the values of hardness of the weld metal zone were more high than that of the base metal. And their corrosion resistance were also superior to the base metal. The weld metal of A2F(AC SMAW: 2 pass welding with foreign electrode) showed a relatively good results to the corrosion resistance as well as the hardness compared to the ether welding methods and welding materials. Moreover it indicated that hardness of the weld metal by the domestic electrode was considerably high compared to that of the foreign electrode.

  • Purpose - How are gains from trade distributed between countries when economic integration is achieved through free trade? The purpose of this paper is to answer this question. Design/methodology/approach - This study attempts to address the issue of distribution of trade gains between participating countries following economic integration in terms of positive economics. The analysis is therefore based on a theoretical methodology. Findings - First, commodity prices fall and consumer surplus increases in both large and small countries. Second, when economic integration into free trade is achieved, gains from trade always exist in small countries. However, the size of trade gains depends on the degree of difference from the market size of the partner country, the large country. However, the size of the gains from trade depends on the extent of difference between the market size of the large country. If the market size of a large country is much larger and there is a large difference, trade gains will be very large, whereas if the market size is similar, profits of domestic firm will decrease. Therefore, in that case, the size of the gains from trade becomes relatively small because only the gains from exchange exists. On the other hand, in a large country with a large market size, there is a possibility of trade gains only when the market size is similar to that of a small country, which is a trading partner. However, if there is a large difference in market size, the decrease in profits of domestic firm is relatively larger than the increase in consumer surplus due to trade, and rather, a trade loss occurs. Research implications or Originality - Our analysis contributes to filling the gaps in the literature regarding the distribution of gains from trade, and from a policy point of view, it is meaningful in examining the impact of market size, an important variable considered in regional economic integration of countries.

  • The present world is full of challenges and opportunities for the women at work. Every woman works hard for academic growth and professional development. For the same reason they also face challenges every day such as stresses, tensions, problems and competitions. When these factors exceed above the strengths, the capabilities of a woman start drowning under stress. Stress is generally thought negative characteristic, but stress or tension maintained up to some level is necessary and effective towards work done at job. This paper covers the study relationship between job stressor and female teacher's performance. The study was carried out in Government Colleges of District Hyderabad, Pakistan. The teacher student relationship was selected as a stressor for female teachers. The study is descriptive in nature followed by method of correlation. A five point "Likert Scale" was developed to collect the data from the sample size of 158 college teachers drawn randomly and the collected data was assessed quantitatively. The relationship between the "teacher student" (as an indicator of job stress) and "female teachers' performance" was calculated by Pearson Correlation formula. The findings of the study show the significant correlations between the teacher student relationship and job stress in female teachers' performance where it is found that the stressor caused the poor Physical and Mental health of female teachers working in colleges.

  • Objectives : In ministerial-fire theory(相火論) of Zhu Dan-Xi(朱丹溪), the meanings of monarch-fire(君火) and ministerial-fire(相火) described in papers published nowadays are not the same. Therefore, it is necessary to rebuild a clear concept. Methods : To understand the relationships among 'heaven(天)'-'human(人)' and 'name(名)'-'position(位)', the core concept of the ministerial-fire theory(相火論) of Zhu Dan-Xi(朱丹溪), I examined the relationships between 'heaven(天)' and 'human(人)' in Neo-Confucianism(性理學) of Song(宋) Dynasty and reviewed the notes of Wang Bing(王冰) which were quoted by Zhu Dan-Xi(朱丹溪) to set the concept of monarch-fire(君火) and ministerial-fire(相火). I studied relevant texts. Results : In ministerial-fire theory(相火論) of Zhu Dan-Xi(朱丹溪), monarch-fire(君火) is perceived as being from greed(人欲) that can cause hyperactivity(妄動) of ministerial-fire(相火), whereas ministerial-fire(相火) is perceived as being able to control monarch-fire(君火) by following the orders from heaven. This point of view is different from the past which recognized monarch-fire (君火) as the owner and ministerial-fire(相火) as the servant. Conclusions : Zhu Dan-Xi(朱丹溪) received the ideological impact of Neo-Confucianism, and accepted the notes of Wang Bing, recognized monarch-fire(君火) as 'name(名)' and ministerial-fire(相火) as 'position(位)', so he voiced the ministerial-fire theory(相火論) that perceived monarch-fire(君火) as fire(火) of the five processes(五行) of human body that came from greed, ministerial-fire(相火) as being in a position to hear the order from the 'heaven(天)' to control monarch-fire(君火). But the concept of ministerial-fire(相火) which he set connoted a confusing meaning of 'nature(性)' and 'way(道)' of Neo-Confucianism. In the later process to solve the problem, life-gate theory(命門學說) was raised, and many researchers had tried to remove the meaning of hyperactivity from the ministerial-fire(相火).
