Agricultural Innovation Action Strategy Based on Community Development
Authors: Sujimin Sujimin , Kolopaking Lala M , Sjaf Sofyan
Published: May 2019

The development of agriculture innovation tends to be oriented towards the increasing of the farm productivity rather than the equitable distribution living standard for farmer. Thus, the innovations have not only caused the social inequality in villages, but also the inequality of the relationship between rural and urban area. This study emphasizes two objectives, namely to conduct a critical evaluation of an organization that has created many agricultural innovations and to formulates new strategies from the organization to reduce social inequality. The data were gathered using some approaches: literatures study, structured quetionaires interviews, field survey, observation, and focus group discussion. The data collecting was started by reviewing literatures data and continued by interviews to 60 respondents using structured evaluation quetionnaires. The respondents were selected by accident sampling technic. Field survey conducted in the head office of organization, Yayasan Mutiara Keraton Solo (YMKS), Sukamantri Village (Tamansari Sub-District, Bogor Regency) and Sambirejo Village (Plupuh Sub-District, Sragen Regency) started from March to June 2018. In depth interviews were orginised in focus group discussion to 16 informans. The focus group discussion was conducted to construct the strategies of the organizational action in the future. The result of the study indicate that the performance of YMKS, established in 1994, is in a good criteria. However, the YMKS has a business vulnerability that is not continuous if the organization does not find a new strategy to maintan its existence. The organization has come characteristics such as innovative agricultural institution with involving society, social business organization for increasing farm productivity, and institution for citizen development. This study concludes that there are 5 (five) strategies and 4 (four) action programs that should be developed by the YMKS containing basic social values related to the importance of the increasing quantity and quality of human resources carried out together to create the farmer regeneration as youth agricultural innovators. In addition, the strategy and action also include the development of ideas so that actions are carried out on the basis of strengthening for the collaborative network in the “Working Together” shceme to establish Business-Community as a driving factor for community development acitivities. The thesis, however, highlight that this action is a new way of agricultural innovation encouring efforts to overcome social inequality.

Published: May 2019

The fractures in coal and rock mass are the main channels of gas seepage, and understanding the gas migration law during mining is the precondition of gas control. The long-term in-situ monitoring of the abutment pressure, fracture networks and gas-flow in front of a mining face was carried out and the 1-D connectivity ratio of boreholes were calculated. The results showed that under the influence of mining, the fracture networks developed to the depth of rock stratum, and as far-field gas seepage channels, far-field gas continuously supplied the near-field gas. The gas flow in front of the mining face have undergone two stages of evolution from initial value to peak value, and then to a stable value. The 1-D connectivity ratio the abutment pressure about 5 to 10 m. The 1-D connectivity ratio reflected the dergree of coal and rock fracture penetration caused by mining, and the area with the highest gas extraction efficiency was the transition zone from peak abutment pressure to residual pressure in coal seams.

Published: May 2019

This paper addresses the non-equilibrium condensation (NEC) in supersonic steam ejector under the assumptions of no slip velocity between the droplets and vapor phase and homogenous nucleation. The experimental data carried out by Moore has been used to verify the numerical results. It is illustrated that the maximum value of the flow mach number of the NEC model is lower than that of the equilibrium condensation model, and NEC model increases the ejector?s entrainment ratio in comparison equilibrium condesation model. When using the NEC model, the nucleation characteristics such as subcooling degree, nucleation rate could be obtained in ejector flow field.

Authors: Lu Yi-Qiang , Liu Xiao-Hui , Xie Jing , He Zhi-Qiang , Li Cong
Published: May 2019

Coal specimens from baijiao coal mine were impacted by a split Hopkinson pressure bar to study its dynamic mechanical behavior under different confining pressures (0-12 MPa) and different strain rates (20-250 s-1). The performances and the energy evolution characteristics of the coal specimens were analyzed. The results show that the strengthening effect and toughening effect of rock are gradually enhanced with the increase of confining pressure. At the same time, the coal failure gradually transitions and develops from tensile failure to compression-shear failure under the action of confining pressure. The peak strength and peak strain of coal rock show significant strain rate correlation and strong confining pressure effect with the change of confining pressures and strain rates. The dynamic strength growth factor of coal is approximately linear with the increasing of strain rates. The energy density and energy absorption density increase linearly with the increase of strain rates, and the energy consumption ratio has a logarithmic growth relationship with the strain rates.

Bilinearization and fractional soliton dynamics of fractional Kadomtsev-Petviashvili equation
Authors: Zhang Sheng , Wei Yuanyuan , Xu Bo
Published: May 2019

Kadomtsev-Petviashvili equation is a mathematical model with many important applications in fluids. In this paper, a local fractional Kadomtsev-Petviashvili equation with Lax integrability is derived and solved by extending Hirota?s bilinear method. More specifically, the local fractional Kadomtsev-Petviashvili equation is derived from a local fractional Lax equation. With the help of a suitable transformation, the local fractional Kadomtsev-Petviashvili equation is then bilinearized. Based on the bilinearized form, n-soliton solution with Mittag-Leffler functions is obtained. In order to gain more insights into the fractional n-soliton solution, the velocity of the fractional one-soliton solution is simulated. It is shown that the velocity of the fractional one-soliton changes with the fractional order.

A preliminary study for refinement of equity preference questionnaire
Authors: Park SeungRib , Suh Yongwon
Published: May 2019

Equity Preference Questionnaire (EPQ; Sauley & Bedeian, 2000) was developed as an alternative measure of Equity Sensitivity Instrument (ESI; Huseman, Hatfield, & Miles, 1987) assessing the construct of equity sensitivity. However, EQP appeared to have sub-dimensions, making it difficult to explain which the sub-factors are relavant to the equity sensitivity and causing the dispute on the validity issue, including the multidimensionality, of the measure. Current study, by using the principal component analysis, was able to confirm that EPQ was unidimensional. Besides, with the use of Item Response Theory (IRT; Embretson, & Reise, 2000), the EPQ measuere was investigated at the item level, which was unable to precisely estimate, in the classical test theory, the trait of both ‘Benevolents’ and ‘Entitleds’ comprised of equity sensitivity. Based on the results of both item and test information funcion in IRT, 6 out of 16 items were dropped from the measure due to the lack of the item information. The modified EPQ resulted in single factor as originally devised by Sauley and Bedeian(2000), and the predicting power of the revised measure remained stable. Implications are noted for further inquiry into refinement of modified EPQ.

In the first study, Relationship quality dimension variables (trust, promotive interdependence) were used to identify moderating effects. For study 1, data were collected from 400 employees using survey questionnaires. The results showed that high level of trust and promotive interdependence buffer the effects of task conflict on relationship conflict. In study 2, Individual difference dimension (self-esteem, interpersonal sensitivity) variables were used. The data were collected from 269 employees using survey questionnaires. The results revealed that high level interpersonal sensitivity reduced the effects of task conflict on relationship conflict. Finally, implications and limitations of these results were discussed.
Latent profile analysis ofemotional labor strategies in subordinate roles
Authors: Yeum Soran , Kim MyoungSo
Published: May 2019

The purpose of this study was to (1) confirm how employees utilize each regulation strategy of emotional labor(surface and deep acting) based on person-centered approach and (2) to examine determinants for each profile and the relationship between each profile and job effectiveness. A total of 507 employees working in a variety of different fields in Korea participated in an on-line survey. To identify sub-populations of emotional labor strategies in subordinate roles, latent profile analysis was adopted. The results indicated that five groups(surface actors, deep actors, non actors, low actors, regulators) were classified. In addition, each group was significantly distinguished by the antecedents of social stressor and leader trust, also related to various outcome variables(i.e., burn-out, job engagement, turn-over intention, felt-inauthenticity). These results showed how variables operate within people and shed light on variable-centered approach ignoring the possibility of distinct combinations of emotional regulation strategies. On the basis of the results, the implications and future research directions were discussed.

Differences in emotion regulation strategies across time and situational contexts among emotion laborers
Authors: Kim MinYoung , Kim Sohee
Published: May 2019

This study investigated emotional experience and emotion regulations among emotional laborers at work and off work across work years. In order to make a cross-sectional approach, 165 cabin crews were recruited from a commercial airline in Korea, whose work experiences varies from 1 month to longer than 16 years. The results of regression analysis showed that negative emotional experiences were explained by work years. However, positive emotional experiences reduced among laborers with up to around 8 work years and then increased. Such curvlinear pattern was also found in cognitive reappraisal, which is a type of emotion regulation strategies. In addition, we conducted moderation analyses to investigate the association between emotion regulation at work and off work in terms of work years. The results showed that the association between cognitive reappraisal at work and off work were stronger among laborers with short work years than those with long work years. These findings suggest that the maladaptive consequences of emotional labor such as less positive emotional experiences, less cognitive reappraisal, and more spillover effect may tone down at some point of work years. Theoretical implications and suggestions for practitioners were included.

Mechanical Adaptability of Artificial Muscles from Nanoscale Molecular Action
Authors: Lancia Federico , Ryabchun Alexander , Nguindjel Anne-Déborah , Kwangmettatam Supaporn , Katsonis Nathalie
Published: May 2019

The cooperative operation of artificial molecular motors and switches has been amplified in polymer-based approaches that have led to versatile motion at the macroscale. As these active, shape-shifting polymers have become ever more sophisticated in their morphing capabilities, a major remaining challenge is to encode muscle-like mechanical adaptability during their operation and to explore its molecular origin. Here, we describe the mechanical adaptability of materials in which the light-induced action of molecular switches modifies the intrinsic interfacial tension, in a phase heterogeneous design featuring a liquid crystal polymer network swollen by a liquid crystal. When the swelling creates sufficient interfacial tension, light triggers an unprecedented and reversible photo-stiffening, analogous to myosin-powered muscle fibers. These mechanoadaptive materials adjust their stiffness to the task they must perform, also while they move, and display muscle-like behaviour that might contribute significantly to the development of human-friendly and soft robotics.
The Pattern of Acetylation Defines the Priming Activity of Chitosan Tetramers

Published: May 2019

The biological activity of chitosans depends on their degree of polymerization (DP) and degree of acetylation (DA). However, information could also be carried by the pattern of acetylation (PA): the sequence of β-1,4-linked glucosamine (deacetylated/D) and N-acetylglucosamine (acetylated/A) units. To address this hypothesis, we prepared partially-acetylated chitosan oligosaccharides from a chitosan polymer (DA=35%, DPw=905) using recombinant chitosan hydrolases with distinct substrate and cleavage specificities. The mixtures were separated into fractions DP4–DP12, which were tested for elicitor and priming activities in rice cells. We confirmed that both activities were influenced by DP, but also observed apparent DA-dependent priming activity, with the ADDD+DADD fraction proving remarkably effective. We then compared all four mono-acetylated tetramers prepared using different chitin deacetylases and observed significant differences in priming activity. This demonstrates for the first time that PA influences the biological activity of chitosans, which can now be recognized as bona fide information-carrying molecules

In this study, the connection between Islamic values and country policies has been carefully connected to the foundations that create political legitimating and the basic nature of a country. Islam performs a crucial part in the social fabric of Pakistan and has been integrated as the guiding concept for the constitutional procedure and governmental systems of the country but at the same time produced implicit stress for their future improvements. Various government authorities have used religious beliefs for their quest for governmental authenticity and power. This has consequently brought about politicization of spiritual explanation in Pakistan demonstrated in the form of sectarian disputes, persecution of spiritual unprivileged or disempowerment of certain spiritual organizations and management. Whereas controversy about interpreting religious identity continues pervading the Pakistani community, it is observed that large parts of the Pakistani inhabitants follow pluralistic types of Islam based on heterogeneous spiritual and devotional methods. Islamic political parties should cooperate on federal or provincial levels with national and local political parties to eliminate the religious extremism in Pakistan.
