The concept of co-creation with consumers has been extensively studied in the literature documented in innovation management and marketing literatures. In this study, we contribute to the literature threefold. First, we develop a model to investigate how co-creation with fans enhance purchase intent and engagement of other customers. Second, we test the model using the data collected from consumers on four different product categories including beer, car, cosmetics and travel. By doing so, we examine the differences between product vs. service as well as different product categories. Third, we will compare the results with that of ordinary consumers to check if there are any differences in the case of co-creating with fans. Most of the extant studies have found a positive effect of co-creation on the outcome evaluation. However, engaging other consumers by co-creation with fans has not been studied. For bridging this research gap, we developed a conceptual model to investigate the antecedents and consequences of co-creation with fans. The hypotheses are as follows. H1: Product class involvement and domain specific knowledge affect perception on co-creation positively. H2: Perception on co-creation affects purchase intent and word-of-mouth positively. H3: The relationships of H1 and H2 differs depending on product categories. H4: The relationships of H1 and H2 differs if companies work with ordinary customers or fans. We tested the hypotheses with the data collected from consumers an online questionnaire survey. Data collection was conducted through a market research agency in 2016 for beer and cars, and in 2019 for cosmetics and travel. The data was collected from 240 consumers in their 20s, 30s, and 40s in Japan. Each segment has same number of males and females, 40 people each for six segments. The findings shed a new light on the co-creation literature and help companies to design better co-creation with fans in different product and service categories.

This work reports the syntheses of an inexpensive and efficient asphalt-derived mesoporous carbon (AdMC) as an adsorbent. The adsorbent was activated with potassium hydroxide to increase its surface area and then characterized by SEM–EDS, FT-IR, and BET. The adsorption properties of AdMC were evaluated for the adsorptive removal of eleven Poly Aromatic Hydrocarbons (PAHs) and diesel from water samples. The prepared AdMC showed very high surface areas and high micropore volumes equal to 2316 m2/g and 1.2 cm3/g, respectively. Various experimental conditions influencing the adsorption capacity of eleven PAHs and diesel were investigated. At high concentrations, PAHs and diesel solubility in water is very low. Hence, samples were emulsified with a surfactant, and then maximum adsorption capacity was investigated. Adsorption profile of individual PAHs was examined using gas chromatography/mass spectrometry analysis followed by liquid–liquid extraction. Total hydrocarbon removal was studied using a total organic analyzer. Asphalt-derived mesoporous sorbent showed an extreme ability to remove PAHs and diesel (average adsorption capacity of 166 mg/g for individual PAHs and diesel (maximum capacity of 1600 mg/g). The experimental results fitted the Langmuir model with a correlation efficiency of 0.9853. The results obtained for both adsorbents also matched to pseudo-second-order kinetics, suggesting that the adsorption of PAHs and diesel is chemical, monolayer, and homogeneous process.

The aim of this work is to investigate the ability of a new functionalized graphene oxide 3-amino-5-phenylpyrazole (F-GO) in the adsorption and removal of Hg2+ from aqueous solution. Both untreated graphene oxide (GO) and F-GO were characterized using FT-IR, EDX, FE-SEM, XRD and TGA analysis. The effects of three operational variables (pH, adsorbent dose and initial metal ion concentrations) on Hg2+ adsorption capacity of F-GO were investigated by central composite design. This technique aims to find a simple way to optimize the adsorption process and to analyze the interaction between the significant parameters. A quadratic model suggested for the analysis of variance found that the adsorption of metal ions heavily depend upon pH of the solution. The adsorption mechanism has been determined by pseudo-first-order kinetic models and the adsorption behavior was modeled by Freundlich isotherm. Results demonstrated that the adsorption capacities of F-GO for removal of Hg2+ were generally higher than those of GO, which is attributed to a decrease in the agglomeration of graphene layers due to the presence of amino-functional moieties with their bulky phenyl groups. Thermodynamic data indicated that the functionalization significantly affects the thermostability of the GO precursor materials. The desorption study demonstrated favorable regenerability of the F-GO adsorbent, even after three adsorption–desorption cycles.

Objectives: This systematic review examined the association of animal-assisted interventions (AAI) with quality of life (QoL) for pediatric oncology patients, for potential use in occupational therapy practice. Methods: Articles published in peer-reviewed journals between 2002-2019 from PubMed, MEDLINE, CINAHL, American Journal of Occupational Therapy (AJOT), Journal of Oncology, SCOPUS, and OTSeeker were selected for AAI with therapy dogs specific to the target population of pediatric oncology patients undergoing treatment in clinical settings. Results: Moderate evidence was found for AAI and mood improvement, pain reduction, and stress relief; and low-level evidence supported AAI for decreasing anxiety. The most significant AAI improvements were seen in perceptions of pain, stress levels, and mood. Discussion: Evidence suggests that occupational therapists may want to consider incorporating AAI into therapy sessions as it serves as a distraction and short-term coping strategy for children undergoing oncological treatment.

In this paper, AgCl/Ag3PO4/diatomite photocatalyst is successfully synthesized by microemulsion method and anion in situ substitution method. X-ray diffraction (XRD), photoelectron spectroscopy (XPS), scanning electron microscopy (SEM), energy dispersive spectroscopy (EDS), transmission electron microscopy (TEM), and ultraviolet-visible spectroscopy (UV-Vis) are used to study the structural and physicochemical characteristics of the AgCl/Ag3PO4/diatomite composite. Using rhodamine B (RhB) as a simulated pollutant, the photocatalytic activity and stability of the AgCl/Ag3PO4/diatomite composite under visible light are evaluated. In the AgCl/Ag3PO4/diatomite visible light system, RhB is nearly 100 % degraded within 15 minutes. And, after five cycles of operation, the photocatalytic activity of AgCl/Ag3PO4/diatomite remains at 95 % of the original level, much higher than that of pure Ag3PO4 (40 %). In addition, the mechanism of enhanced catalytic performance is discussed. The high photocatalytic performance of AgCl/Ag3PO4/diatomite composites can be attributed to the synergistic effect of Ag3PO4, diatomite and AgCl nanoparticles. Free radical trapping experiments are used to show that holes and oxygen are the main active species. This material can quickly react with dye molecules adsorbed on the surface of diatomite to degrade RhB dye to CO2 and H2O. Even more remarkably, AgCl/Ag3PO4/diatomite can maintain above 95 % photo-degradation activity after five cycles.

The pregnancy rate in indigenous ewes inseminated with frozen-thawed Suffolk semen following natural and synchronized estrus was determined. The serum Progesterone and Estrogen concentration and vaginal electrical resistance (VER) of ewes at the time of Artificial Insemination (AI) were observed as successful pregnancy determinants. 21 healthy ewes were selected for this experiment during January-April, 2017. 10 ewes were inseminated in natural estrus. Whereas, 11 ewes were inseminated after estrus synchronization using intravaginal sponges containing 60 mg medroxyprogesterone acetate. Trans-cervical Al (TCAI) was performed in all ewes within 12-16 hours of observed heat. Prostaglandin E1 analogue impregnated vaginal sponge was used for cervical relaxation 6-8 hours before insemination. Pregnancy was diagnosed through trans-abdominal ultrasonography after 40 days of AI. The pregnancy rate of ewes in synchronized estrus was higher (54.5%) than in natural estrus (30%). Higher serum Progesterone level (0.90 ± 0.02 ng/mL) and significantly (p < 0.001) lower VER (257.78 ± 10.11 ohm) were observed at the time of AI in ewes becoming pregnant. Results suggest that higher Progesterone concentration and lower VER could be considered as pregnancy indicators. Oestrous synchronization could be implemented to increase the pregnancy rate in ewes.

Background: Ageism is recognized as a concern in the context of a rapidly aging population. Current literature acknowledges the outcomes of ageism toward older adults, however there has been little focus on the reciprocal effect toward young people. Programs geared at reducing ageism toward older adults show positive outcomes for both generations. This review explored the importance of intergenerational relationships and assessed the effectiveness of intergenerational programs on decreasing ageism toward young people. Method: A comprehensive database search was conducted to identify eligible studies published between 1989 and 2019. To be considered for final inclusion, studies had to implement an intergenerational program with outcome measures specifically addressing older adults’ attitudes toward young people. Results: Of the 4,661 articles retrieved, 12 studies were included with 1,570 participants. The specific intergenerational interventions differed, but commonalities included extended contact, community-based activities, and mentorship. Eleven of the twelve articles yielded statistically significant effects in reducing ageism toward young people. Evaluation of program outcomes resulted in four themes. Conclusion: Moderate evidence supports the effectiveness of intergenerational programs on reducing ageism toward young people. These results describe the literature and support the reciprocal effectiveness of these programs. Occupational therapists can be instrumental in promoting reduced ageism across the lifespan.

구조와 사육환경이 동일한 3개의 돈방(room A~C)에서 48일 동안 비육돈의 암모니아 농도 및 환기량을 모니터링하여 배출계수를 산정하였다. 실험 결과, 온도 22.5℃, 습도 53.9% 환경에서 평균 암모니아 순발생 농도 5.93 ppm, 환기량 23.7 m3/h·pig로 나타났다. 일별 상관관계 분석결과, 암모니아 농도는 온도와 음의 상관관계(R2: -0.65 ~ -0.53)를 가지는 것으로 나타났으며, 환기량은 암모니아 농도에 거의 영향을 미치지 않는 것으로 나타났다. 암모니아 농도는 이른 오전을 기점으로 서서히 증가 경향을 보이다가 12~13시경 최댓값에 도달하였고, 상호 상관도가 높은 온도, 습도, 환기량의 경우 14~15시에 최댓값을 갖는 것으로 분석되었다. 시간별 데이터 상관관계 분석결과, 암모니아 배출량에 영향을 미치는 요소는 암모니아 농도(R2=0.71)와 환기량(R2=0.61)으로 이 중, 암모니아 농도가 더 상관성이 높은 것으로 분석되었다. 암모니아 배출계수는 2.28 g/d·pig로 분석되었다.

The formulation of Halal and Catering Regulation on board is a new draft proposal in shipping industry in the nation to ensure Muslim seafarers will be protected under social welfare. Currently, there are no regulations in place regarding the formulation of provision of Halal and Catering which have been enforced by several authorities at different sector in the nation. However, Halal JAKIM is an expert and focal point with the right to issue Halal certification not only in this nation but globally. The main objective of the study was to form a Halal committee on board for the co-ordination of responsibilities between the agencies, and the second objective was to establish the Halal and Catering Regulations on the merchant vessel for the Malaysian flag. The problem is that seafarers feel insecure about the preparation of halal food and no regulations have been issued to date. In fact, this study requires Qualitative methods because several actions related to the Halal-Toyibban Policy and food preparation rules should be obtained through closed-ended interviews with Halal regulatory experts, ship-owners, and selected stakeholders. Therefore, the analytical process will refer to the use of transmitted transitions from oral to text through the coding system in facilitate the content analysis process; and further to the level of discussion and findings. Ship-owners should ratify the Halal and Catering Regulations once they are enacted. The results of this study are expected to formulate the framework for the Halal and Catering Committee involving the agency by reference to interdependent theory. The second finding was to formulate a draft of the Halal and Catering Regulations on the Malaysian merchant vessel by reference to the application of benchmarking theory. Finally, this study will benefit the Muslim seafarer with the cooperation of the ship-owner and the relevant government agencies.

Global warming, or climate change, could be the main reason why small islands in many areas of the Earth, including those in Indonesian territory, are sinking. Many small Indonesian islands are between 1 and 3 metres under the surface of the sea because of raised sea levels caused by climate change. If this situation continues, it would affect many of the outermost islands of Indonesia, so that we should anticipate the danger that the outermost islands would be submerged. The basepoints and archipelagic baselines would then be replaced, among other serious consequences for Indonesia. The Paris Climate Agreement, signed by almost 200 states in 2015, is the main instrument for mitigating global warming through reducing the emission of greenhouse gases. Indonesia ratified the Paris Climate Agreement, because it has a great interest in mitigating the phenomenon that is causing the sea level to rise, which is having a serious impact on its islands.

The fish influx and behavioral properties at a set-net off Goseong, South Korea were investigated using an imaging sonar. As a result, the average influx of fish was 33.9% at day time and 66.1% at night time, respectively, which indicated that a majority of fish entered into a playground in the set-net at night. The fish behavioral properties such as target (fish) length, range, orientation and major-axis angle were examined and compared among survey dates (4, 5, and 6 June 2019) using the statistical analysis tool (analysis of variance, ANOVA). The behavioral properties presented differently sometime of survey dates. This is preparatory study to support fish behavior properties in a set-net. It is expected that more elaborated behavioral information of fishes in the set-net is beneficial for designing and deploying a set-net fishing gear as well as general fish behavior research in the future.

The possibility of orange pulp utilization for nanoporous carbons production was investigated. Moreover, processing the obtained materials as limonene oxidation catalysts was studied as well. Limonene was separated from orange pulp obtained from fragmented orange peels—the waste from industrial fruits processing—by means of simple distillation. After the separation of limonene from the biomass, the dried orange pulp was converted to three types of nanoporous carbon catalysts: without activating agent, with NaOH, and with KOH. The catalysts were characterized by XRD, SEM, EDX, AFM, and sorption of N2 methods. The activities of the obtained catalysts were tested in the oxidation of limonene to perillyl alcohol (the main product), carveol, carvone, and 1,2-epoxylimonene and its diol. In the oxidation processes, hydrogen peroxide was used as the oxidizing agent. This work has shown for the first time that nanoporous carbons obtained from orange pulp waste, after separation of limonene, are active catalysts for limonene oxidation to industrially important value-added products.

We report an analysis of two poorly studied eclipsing binary stars, GSC 04396-00605 and GSC 04395-00485 (recently named V455 Dra and V454 Dra, respectively). Photometric data of the two stars were obtained using the 1-m Korean telescope of the LOAO operated by KASI while monitoring the cataclysmic variable DO Dra in the frame of the Inter-Longitude Astronomy (ILA) project. We derived periods of 0.434914 and 0.376833 days as well as initial epochs JD 2456480.04281 and JD 2456479.0523, respectively, more accurate than previously published values by factors 9 and 6. The phenomenological characteristics of the mean light curves were determined using the New Algol Variable (NAV) algorithm. The individual times of maxima/minima (ToM) were determined using the newly developed software MAVKA, which outputs accurate parameters using "asymptotic parabola" approximations. The light curves were approximated using phenomenological and physical models. In the NAV algorithm, the phenomenological parameters are well determined. We derived physical parameters using the Wilson-Devinney model. In this model, the best-fit parameters are highly correlated, thus some of them were fixed to reasonable values. For both systems, we find evidence for the presence of a cool spot and estimate its parameters. Both systems can be classified as overcontact binaries of EW type.

Introduction: Age-related co-morbidities are common among persons living with chronic Human Immunodeficiency Virus (HIV). However, data are largely absent on the relationship between frailty and incontinence as related to falls—common age-related co-morbidities—among people living with chronic HIV (PLWH). Methods: To inform hospital-based Occupational Therapy (OT) services for PLWH, we performed a case-control study using extracted data from the electronic medical records of PLWH who had received OT at a large academic hospital. Two-hundred-and-four subjects were included in the final dataset; sixty-eight were cases that reported a fall within the last 12 months, while 136 were controls which were PLWH who had not sustained a fall. Results: The association between falls and frailty indicated that persons categorized as ‘pre-frail’ with balance deficits were more likely to fall (OR=2.77 [1.18-6.52]). Women who lacked insurance were less likely to fall (OR=0.38 [0.18-0.82]) and (OR=0.29 [0.09-0.88]) respectively. The association between incontinence and falls among PLWH were not statistically significant in a multivariate adjusted regression model (OR=1.38 [.59-3.22]). Conclusion: Our findings suggest further examination of the person factors of PLWH who are categorized clinically as ‘pre-frail’ or ‘frail’ may improve health outcomes and reduce falls when paired with occupation-based interventions.

The objective of this research work was to know ovarian dynamics and pregnancy rate of cyclic Murrah buffalo cows with induced estrus by administration of prostaglandin F2α (PGF2α) and timed artificial insemination (TAI) with frozen thawed semen. A total of 31 female buffaloes were selected for the study. The buffalos having matured CL observed by ultrasonography were given one intra muscular injection of cloprostenol 500 μg and TAI was performed using frozen thawed semen of Indian Murrah buffalo bull. Results showed that 90.32% (significantly, at p < 0.05) cows explore the sign of heat after injection of PG and 67.85% (significantly, at p < 0.05) cows were become pregnant out of 28 inseminated (TAI) cows. In the 28 inseminated (TAI) cows, average number of smaller and larger size of follicles were non-significantly (p > 0.05) higher at day 3 post PG injection, but the medium size of follicles was non-significantly (p > 0.05) higher at PG injection. At day 3 post PG injection the diameter of follicles was significantly (p < 0.05) higher, but the diameter of CL was significantly (p < 0.01) lower compared at PG injection. At PG injection the diameter of largest follicle was non-significantly differences (p > 0.05) in between pregnant and non-pregnant cows. But at day 3 post PG injection it was significantly (p < 0.01) higher in pregnant cows compared to non-pregnant cows. The number of small, medium, and large follicles at PG injection and at day 3 post PG injection were non-significantly (p > 0.05) difference in between pregnant and non-pregnant buffalo cows. Finally, it is concluded that the CL was effectively regresses and induced the sign of heat in buffalo cows and after AI the cows were become pregnant with significant rate. The study will help to the veterinarian and researcher to know the efficacy of PG injection and AI for reproductive efficiency in buffalo cows.

At q = 1.81 ± 0.20 × 10-5, KMT-2018-BLG-0029Lb has the lowest planet-host mass ratio q of any microlensing planet to date by more than a factor of two. Hence, it is the first planet that probes below the apparent "pile-up" at q = 5-10 ×10-5. The event was observed by Spitzer, yielding a microlens-parallax πE measurement. Combined with a measurement of the Einstein radius θE from finite-source effects during the caustic crossings, these measurements imply masses of the host Mhost = 1.14+0.10-0.12 M⊙ and planet Mplanet = 7.59+0.75-0.69 M⊕, system distance DL = 3.38+0.22-0.26 kpc and projected separation a⊥ = 4.27+0.21-0.23 AU. The blended light, which is substantially brighter than the microlensed source, is plausibly due to the lens and could be observed at high resolution immediately.

식중독(식품 매개 질병)은 전 세계적으로 심각한 공중 보건 문제와 경제적 손실을 초래한다. 최근 몇 년 간 새로이 발생한 식중독은 주로 동식물에서 유래하는 새로운 박테리아, 바이러스, 원생 동물, 곰팡이독, 그리고 프리온 에서 발생했다. 유해 박테리아, 바이러스, 기생충 또는 화학 물질이나 자연 발생 독소 등으로 오염된 불안전한 음식의 섭취는 질병의 발병률과 사망률을 높인다. 그러나 특정 병원성 또는 화학적 위험요인, 불충분한 보고 사례, 감염 전염 방식 및 시기 진단 등에 대한 식품 소재 귀인(歸因)의 어려움 때문에 식중독의 발병률과 부담을 추정하는 것은 전 세계적으로 큰 도전이며 식중독을 통제하 는 것은 매우 어렵다. 그러므로 종합적인 식품 안전 전략 및 정책의 시행, 관리 감독 강화, 탄력적인 건강 시스템 보장, 안전한 식품 보장 및 식품 매개 질병 예방을 위한 교육 및 훈련 강화에 대해 모두가 책임져야 한다.

In this paper, we report graphene composite membranes prepared by transfer of a layer of chemical vapor deposition graphene onto porous anodic alumina (AA) substrates with nominal pore size 20 and 30 nm, referred as 20AA and 30AA. The coated and uncoated substrates were characterized using optical and electron microscopy techniques. The bare substrates exhibited a smooth surfaces with a well-organized array of hexagonal pores, displaying an average pore size of 17 ± 3 (20AA) and 23 ± 3 nm (30AA). The scanning electron microscopy and atomic force microscopy analyses confirmed the successful transfer of graphene layer onto the target substrates. The molecular transport study was performed by introducing 0.5 M potassium chloride (KCl) and deionized water in a Side-bi-Side Franz diffusion cell. The graphene/20AA specimen blocked 66% ions transport, and graphene/30AA membrane about 64%. The ions blockage exceeded 90%, near the characteristics of defectfree graphene when the defects of the transferred graphene were sealed with Nylon 6,6. The results of this study suggest the potential use of graphene on AA substrates for water desalination and gas purification applications.

Objective: To evaluate item-factor structures of the 15 sensory items from the Survey of Pathways to Diagnosis and Services (Pathways) and examine the best fitting model. Methods: The study subjects were 1,968 children aged 6-17 years, who had ever been diagnosed with Autism Spectrum Disorder (ASD) and/or Intellectual Disability (ID). Factor analyses and item response theory models were used to determine the best fitting item-factor structure of the sensory items. The Strengths and Difficulties Questionnaires (SDQ) was used to test the concurrent validity of the sensory severity estimates. Results: A bifactor MIRT model (a general and four sensory factors) was selected as the best fitting model. All items statistically fitted to the bifactor model (p > .01) and showed moderate correlations with all five subscales of the SDQ (r s = .31 ~.51, p < .0001). The general sensory score differentiated the four different diagnostic groups (ASD, ID, ASD with ID, and no current symptoms) [F (3,1961) = 207.4, p < .0001]. Conclusion: The Pathways sensory items yielded reliable estimates of the general and each corresponding sensory factor by applying a bifactor MIRT model. The sensory score can be used as a valid sensory measure in the population survey.
