With the popularization and application of artificial intelligence technology in daily life, new ethical and moral problems constantly appear in human society. These ethical and moral problems have been associated with people's moral behavior and have become crucial issues. In traditional social situations, researches have proved that moral intensity affects people's moral behavior. However, in the context of applying artificial intelligence technology, the mechanism between moral intensity and moral behavior is unknown. Therefore, this study focuses on the relationship between moral intensity and moral behavior in the context of applying artificial intelligence technology, and introduces a new concept - technology moral sense (TMS) into the theoretical model. Research method: We set various situations of applying artificial intelligence technology and adopt the situational experiment method to analyze the relationship between moral intensity and moral behavior in different application scenarios. The results show that moral intensity has a significant influence on moral behavior, while the technology moral sense performs a mediating function.

In this paper, the interfacial stress intensity factors( $K_{i}$＝ $K_1$＋i $K_2$) for the edge interface crack in the dissimilar materials(isotropic-isotropic materials, isotropic-composite materials) were analysed by BEM(Boundary Element Method). The fatigue crack growth behaviour was investigated by load constant fatigue test. From the experimental results, the relationship between da/dN and interfacial stress intensity facto, ( $K_{i}$ or $K_1$) can be expressed by Paris'law for homogeneous materials.s.s.

Using artificial rainfall simulator, the soil loss, which is deemed as most cause of muddy water problem among Non-point source(NPS) pollutant, was studied by the analysis of direct runoff flow, groundwater runoff, and groundwater storage properties concerned with rainfall intensity, slope of area, and land cover. The direct runoff showed increasing tendency in both straw covered and bared boxes which are 5%, 10%, and 20% sloped respectively. Also the direct runoff volume from straw covered surface boxes were much lower than bared surface boxes. It's deemed as that the infiltration capacity of straw covered surface boxes were increased, because the surface sealing by fine material of soil surface didn't occurred due to the straw covering. Under the same rainfall intensity and slope condition, 2.4 ${\sim}$ 8.2 times of sediment yield were occurred from bared surface boxes more than straw covered surface boxes. The volume of infiltrated were increased due to straw cover, the direct runoff flow were decreased with decreasing of tractive force in surface. To understand of relationship the rate of direct runoff flow, groundwater runoff, and groundwater storage by the rainfall intensity, slope, and land cover, the statistical test was performed. It shows good relationship between most of factors, expect between the rate of groundwater storage and rainfall intensity.

표준화에 대한 투자와 연구개발에 대한 투자는 중소기업의 기업운영 방향성을 결정짓는 두 가지 주요한 전략이다. 동 연구는 중소기업의 표준화에 대한 투자가 기업의 매출 성과에 미치는 영향을 알아보고자 한다. 특히, 단순히 표준화 집중도를 살펴보는 것이 아니라 표준화에 대한 집중도와 연구개발에 대한 집중도를 함께 고려한 기업의 매출 성과에 미치는 영향을 분석하고자 한다. 2013년 한국표준협회에서 수행한 한국표준조사를 바탕으로 정보통신산업과 전기전자산업에 속하는 821개 기업을 대상으로 회귀분석을 수행하였다. 그 결과 중소기업의 연구개발 집중도 대비 표준화에 대한 투자는 그 기업의 매출 성과에 비선형관계(U자형)가 있음을 알 수 있었다. 본 연구결과는 중소기업의 경우 표준화에 대한 집중도 혹은 연구개발에 대한 집중도가 균형을 갖춘 접근보다는 하나에 집중하는 것이 매출성과에 도움 된다는 것을 시사한다.

Recent settlements and sinkhole openings in urban areas have caused social problems such as damage to roads and structures, fear of the public, and loss of property. Several studies have demonstrated that surface subsidence and sinkhole opening are greatly affected by rainfall and rainfall intensity in urban areas. In this paper, we analyzed the relationship with the characteristics of recorded rainfall data using the ground subsidence database reported in major cities. The correlations were found using sedimentation and precipitation data from 2010 to 2014. The duration and intensity of a given precipitation have evolved to obtain an effect on ground sedimentation rate (SR). The results show that the relationship between SR and precipitation is asymptotic and can be modeled by a hyperbolic equation. Through this study, it is possible to predict the occurrence of ground subsidence due to precipitation in advance.

The molecular vibration-activity relationship in the receptor-ligand interaction of adenosine receptors was investigated by structure similarity, molecular vibration, and hierarchical clustering in a dataset of 46 ligands of adenosine receptors. The resulting dendrogram was compared with those of another kind of fingerprint or descriptor. The dendrogram result produced by corralled intensity of molecular vibrational frequency outperformed four other analyses in the current study of adenosine receptor agonism and antagonism. The tree that was produced by clustering analysis of molecular vibration patterns showed its potential for the functional classification of adenosine receptor ligands.

This study was conducted with ginseng plants to investigate photosynthetic response to changes of light intensity and leaf temperature. $CO_2$ uptake in diurnal course was highest in the first phase (8 00~5 : 30 Am.) on May 30, 1992. In $CO_2$ uptake related to stomatal conductance, these relationship was synchronized in diurnal course, but relationship between TEX>$CO_2$ uptake and intercellular $CO_2$ concentration in diurnal course was synchronized oppositely. Leaf temperature and light intensity at the highest $CO_2$ uptake were in the range of 23~$24^{\circ}C$) and 95$\mu$mol.$m^{-2}$.$s^{-1}$), $CO_2$ , respectively. In response to an increasing light intensity under a constant leaf temperature ($18^{\circ}C$), $CO_2$ uptake was increased throughout the light intensity sequence up to 250$\mu$mol.$m^{-2}$.$s^{-1}$), $CO_2$ When $CO_2$ uptake was measured with a series of leaf temperature under a constant light intensity (250 $\mu$mol.$m^{-2}$.$s^{-1}$), $CO_2$ uptake was highest at $18^{\circ}C$ as a 4.1$\mu$mol.$m^{-2}$.$s^{-1}$), $CO_2$ . Similar changes were also observed in stomatal conductance and intercellular $CO_2$ concentration. Evidences from several approaches indicate that synchronization of $CO_2$ uptake, stomatal conductance and intercellular $CO_2$ concentration were closely inter-related and changes of leaf temperature iuluenced the photo-response in photosynthetic processes.

Companies have attempted to build a rational and future-oriented new personnel system in order to adapt and survive in a rapidly changing environment. Recently, Samsung, LG, SK, and CJ, which are large domestic corporations, have been introducing new types of simplified personnel systems competitively. Although there are several prior studies that tried to classify these simplified personnel systems from a strategic point of view, there is a lack of empirical research in terms of the specific types from the perspective of employees. Therefore, in this study, an empirical study on the simplified personnel system which has currently been highlighted was carried out. The relationship between perceived justice (i.e., distributive justice and procedural justice) and organizational effectiveness (i.e., organizational commitment and innovative behavior) were tested. In addition, the mediating role of cognitive attitude as well as the moderating role of cognitive intensity in the simplified personnel system were investigated. The results of structural equation model using 157 survey data show that both distributive and procedural justice have a positive effect on cognitive attitude toward the simplified personnel system, which in turn leads to increased organizational commitment and innovative behavior. Interestingly, it is found that cognitive intensity intensifies the effect of distributive justice on cognitive attitude, whereas it attenuates the influence of procedural justice as expected. This study is among one of the first empirical studies focusing on the simplified personnel system and expands the concept of related variables such as perceived justice, cognitive attitude, and cognitive intensity in this context. Moreover, by clarifying the causal relationship between perceived justice and organizational effectiveness through the roles of cognitive attitude and cognitive intensity, it could provide several practical implications to managers who are interested in the introduction and early settlement of simplified personnel systems in a successful manner.
