An Empirical Investigation of Smart Product Adoption

The advance of information technologies and the Internet have been enabling the transformation of physical products into smart products by embedding information technologies into the products and thereby making them intelligent. The movement to the ‘Internet of Things’ is accelerating connection of the products to the net. While those changes could enhance value propositions of products, they might also cause consumer privacy concerns, which might hinder smart product adoption, because the smartness of the product mainly takes advantage of personal information about the users. This study aims to investigate consumers’ intention to adopt smart products. Building on previous studies on smart products and privacy literature, we propose a research model that explains factors influencing consumers’ intention to adopt smart products. The proposed research model is empirically tested using data from an online survey of consumers. The overall results validate the proposed research model of smart product adoption. Specifically, perceived personalization is found to positively affect consumers’ intention to adopt smart products, whereas information privacy risk decreases the intention. We also find that the attributes of personal information are critical antecedents of consumers’ risk-benefit assessment. The sensitivity of information increases information privacy risk while the congruency of information enhances perceived personalization. Based on the results, theoretical and managerial implications are discussed

Temperament and Character Profiles of Sasang Typology in an Adult Clinical Sample

The purpose of this study was to examine the biopsychological personality profiles of traditional Korean Sasang typology based on the Temperament and Character Inventory (TCI) in a Korean adult clinical sample. A total of 97 adults completed the Korean version of the TCI. The participants were classified as one of three traditional Korean Sasang types (31 So-Yang, 41 Tae-Eum, 25 So-Eum) by three specialists in Sasang typology. The seven dimensions of TCI were compared between the different Sasang types using analysis of variance (ANOVA) and profile analysis. There were no significant differences in age, gender and education across the Sasang types. The TCI profile for each of the Sasang types was significantly different (profile analysis, df = 5.038, F = 3.546, P = .004). There were significant differences in the temperament dimensions of Novelty Seeking (F = 3.43, P = .036) and Harm Avoidance (F = 5.43, P = .006) among the Sasang types. The Novelty Seeking score of the So-Yang type (31.90 ± 9.87) was higher than that of the So-Eum type (25.24 ± 9.21; P = .019) while the So-Eum type (44.64 ± 8.47) scored higher on the Harm Avoidance score compared to the So-Yang type (35.16 ± 11.50; P = .003). There were no significant differences in the temperament dimension of Reward Dependence and Persistence, and the three character dimensions of Self-Directedness, Cooperativeness and Self-Transcendence. Results demonstrated distinct temperament traits associated with traditional Korean Sasang types using an objective biopsychological personality inventory. With further study, the Sasang typology may lead to enhanced clinical safety and efficacy as part of personalized medicine with traditional medicine

Transmetalations in two metal-organic frameworks with different framework flexibilities: Kinetics and core-shell heterostructure

While only a partially transmetalated network was observed in a rigidmetal-organic framework (MOF), not only a completely transmetalated isostructural network but also a partially transmetalated core-shell heterostructural network could be obtained in a flexible MOF by controlling the reaction conditions.close191

Two Dimensions of Family Risk in East Asia: Variations and Contextualization

This paper investigates family risks from the perspective of risk society. Conceptual distinction is made between the first modern and the second modern type of family risk as well as between its objective and subjective dimensions. The major finding in terms of variation of family risks is that the second-modern type of risks is more conspicuous than the first-modern one in Seoul and Tokyo whereas the reverse is the case in Beijing. Yet these two types of risk coexist in all three cities. The contextualized relationship between the objective and subjective dimensions shows the tendency that the risk perception moves up or down in a way reflecting the official statistics of family risks. We argue that this pattern of contextualization can be explained by social construction of risks

Metal-organic framework with two different types of rigid triscarboxylates: Net topology and gas sorption behaviour

A 3-dimensional (3-D) anionic metal-organic framework (MOF), (NH 2(CH3)2)3[Zn6(BTC) 4(BTB)], of an unprecedented 3,3,3,5-c net topology was prepared via the solvothermal reaction of the Zn(ii) ion with two different types of rigid triscarboxylates, 1,3,5-benzenetricarboxylate (BTC3-) and 1,3,5-benzenetribenzoate (BTB3-), as 3-connected nodes, where a structurally rare Zn2(COO)5 cluster serves as a 5-connected secondary building unit. The MOF has a complicated 3-D channel micropore based on three different types of cage-like pores interconnected through the narrow necklike portals of a multiway channel. The MOF that had large solvent-filled pores showed gas sorption behaviour that well matched the pore dimensions and characteristics of the MOF.close1

Conformational control of ligands to create a finite metal-organic cluster and an extended metal-organic framework

While a twofold interpenetrated 3-D metal-organic framework, [Cu-3(L-1)(2)(H2O)(3)]center dot 14DMF center dot 16H(2)O (1) (where, L-1 is 4,4',4 ''-[1,3,5-benzenetriyltris(carbonylimino)] trisbenzoate and DMF is N,N'-dimethylformamide), with a (3,4)-connected pto net topology was prepared using a tricarboxylic acid linked via secondary benzamide as an extended 3-connected node and a Cu paddle-wheel secondary building unit as a planar 4-connected node, another tricarboxylic acid with methylated tertiary benzamide linkage in a folded geometry completely converted its role from diverging to chelating ligand and resulted in a finite Ni-14 metal-organic cluster, [Ni-14(mu(3)-OH) (8)(L-2)(6)(formate)(2)(DMF)(10)(H2O)(2)]center dot 28DMF center dot 14H(2)O (2) (where L-2 is N,N',N ''-methyl-4,4',4 ''-[1,3,5-benzenetriyltris(carbonylimino)]trisbenzoate).close12

Metal-organic framework based on hinged cube tessellation as transformable mechanical metamaterial

Mechanical metamaterials exhibit unusual properties, such as negative Poisson???s ratio, which are difficult to achieve in conventional materials. Rational design of mechanical metamaterials at the microscale is becoming popular partly because of the advance in three-dimensional printing technologies. However, incorporating movable building blocks inside solids, thereby enabling us to manipulate mechanical movement at the molecular scale, has been a difficult task. Here, we report a metal-organic framework, self-assembled from a porphyrin linker and a new type of Zn-based secondary building unit, serving as a joint in a hinged cube tessellation. Detailed structural analysis and theoretical calculation show that this material is a mechanical metamaterial exhibiting auxetic behavior. This work demonstrates that the topology of the framework and flexible hinges inside the structure are intimately related to the mechanical properties of the material, providing a guideline for the rational design of mechanically responsive metal-organic frameworks

Entropically driven self-assembly of a strained hexanuclear indium metal-organic macrocycle and its behavior in solution

The self-assembly of a polyprotic pentadentate ligand, N-cyclopentanoylaminobenzoylhydrazide (H4L4), and an In(III) nitrate hydrate in methanol led to a strained hexanuclear indium metal-organic macrocycle (In-MOM), [In(III)(6)(H2L4)(6)(NO3)(x)(solvent)(6-x)](NO3)(6-x) (where, the solvent is either methanol or a water molecule and x is the number of the nitrate anions ligated). The ligand in the doubly deprotonated state serves as an unsymmetric linear ditopic donor and the alternating indium ions in two different chelation modes serve as two different bent ditopic metal acceptors, which led to a D-3-symmetric hexanuclear In-MOM. Although the hexanuclear In-MOM is enthalpically unfavorable because of the ring strain, the combination of the soft coordination characteristic of the indium ion and the slight ligand deformation from the conjugated planar conformation allows the formation of the entropically favored hexanuclear In-MOM rather than the enthalpically favored octanuclear In-MOM. While the hexanuclear In-MOM is stable in acetonitrile, it partially dissociates into its components in dimethylsulfoxide, and then slowly reaches a new equilibrium state with several different indium species yet to be identified in addition to the free ligand.close4
