THE SPILLOVER EFFECT OF COMMERCIAL CONDOM ADVERTISING ON DATING APPLICATION PREFERENCE AND PUBLIC HEALTH

Jingwen Liu,Yu Ma,Peiliang Sun 글로벌지식마케팅경영학회 2023 Global Marketing Conference Vol.2023 No.07

Commercial condom advertisements usually emphasize the sexual pleasure of branded products, which leads to controversial public views. Some people agree that commercial condom advertisements can also benefit public health, whereas others disapprove of such commercial condom advertisements because their contents are usually offensive, low-tasted, and pornographic. Despite controversy over commercial condom advertising, we know little about the spillover effect of commercial condom advertisement. On one hand, sexual-related content in the commercial condom advertisement may have an arousal effect. That is, it can evoke sexual arousal, leading to more sex intercourses. More frequent sex behaviors, especially casual sex behaviors, may then lead to a risk of contracting sexually transmitted diseases (STDs). On the other hand, commercial condom advertisements may have an educational effect. That is, it can persuade people to use condoms, helping people get in the habit of using condoms, thus reducing the STD trends. In the short term when condom commercials are aired, the arousal effect and educating effect coexists, which motivates the net short-term effect as an open empirical question. In the long-term when the condom commercial no longer aired, the educating effect remains, which decreases the STD trends.

Smoke Image Recognition Method Based on the optimization of SVM parameters with Improved Fruit Fly Algorithm

( Jingwen Liu ),( Junshan Tan ),( Jiaohua Qin ),( Xuyu Xiang ) 한국인터넷정보학회 2020 KSII Transactions on Internet and Information Syst Vol.14 No.8

The traditional method of smoke image recognition has low accuracy. For this reason, we proposed an algorithm based on the good group of IMFOA which is GMFOA to optimize the parameters of SVM. Firstly, we divide the motion region by combining the three-frame difference algorithm and the ViBe algorithm. Then, we divide it into several parts and extract the histogram of oriented gradient and volume local binary patterns of each part. Finally, we use the GMFOA to optimize the parameters of SVM and multiple kernel learning algorithms to Classify smoke images. The experimental results show that the classification ability of our method is better than other methods, and it can better adapt to the complex environmental conditions.

Energy management for households considering uncertainty in solar irradiance with various probability distribution

Jingwen Liu,Wei Wang,Yumin Zhang,Xingming Xu 대한전기학회 2019 Journal of Electrical Engineering & Technology Vol.14 No.5

The electricity load scheduling problem in a household with roof-top photovoltaic (PV) system can efficiently reduce customers’ payments. Compared with previous works in which common flat rate (CFR) has been used, this paper study the case where the time-of-use pricing (TOUP) is adopt. Two conditional equations are constructed for different gains of customers. This is caused by different power direction between the household and the main grid. The two conditional gains equations for the customer are transformed into linear equations by introducing auxiliary variables and linear expression techniques. As a result, established mathematical model to maximize gains for customer is transformed into a mixed integer linear programing (MILP) problem. Thus the resulting MILP model can be easily solved by existing powerful commercial solver. The adjustable and rating power consumption property of appliances are both considered. There are two different mathematic models for them respectively. The impact of reduction of the maximum exchange power between the household and the main grid on gains of the customer, gains of the main grid, load demand during off-peak time and energy exported to the main grid is also studied. The validity and feasibility of the proposed model is illustrated by the case studies.

Jingwen Qiu,Zhengfan Fu,Bin Liu,Yong Liu,Jianhui Yan,Di Pan,Weidong Zhang 대한금속·재료학회 2019 METALS AND MATERIALS International Vol.25 No.6

The wear behavior of Ti–45Al–7Nb–0.3W (at%) alloy prepared by powder metallurgy (P/M) has been investigated using pinon-disk wear tests at the room temperature. The dry sliding wear tests were performed against on a zirconia disk in differentenvironments, viz, argon, hydrogen in nitrogen mixture, air and oxygen. The worn surfaces of Ti–45Al–7Nb–0.3W pins andwear debris were examined by scanning electron microscope, X-ray diffractometer and X-ray photoelectron spectroscopy. It was found that the high Nb containing Ti–45Al–7Nb–0.3W alloy didn’t exhibit better wear resistance in the presence ofoxygen than commercial γ-TiAl (Ti–47Al–2Nb–2Cr–0.2W) alloy. The oxidation on the worn surface and spalling of oxidescaused by the mechanical force during sliding were the main reason for the high wear losses in the air and oxygen. Thezirconia disk underwent a phase transformation caused by the high contact temperature and stress during the sliding tests. The abrasive particles produced in the wear tests largely consisted of the zirconia particles in different environments, exceptin the pure oxygen. The hard zirconia debris was embedded into the friction layer on the worn surfaces of TiAl pins, whichprovided protection against wear to some extent. The main wear mechanisms of Ti–45Al–7Nb–0.3W alloy were abrasivewear of two-body and three-body, some delamination and plastic deformation.

HOW CHINESE CONSUMERS RESPONSE TO FOOD NUTRITION CLAIM

Jingwen Liu,Peng Zou,Qingqing Lu 글로벌지식마케팅경영학회 2016 Global Marketing Conference Vol.2016 No.7

With increasing income and education, requirements to product quality are getting higher in China. Specifically, people tend to nutrition and health now. Food safety has attracted increasing attention due to its importance. The nutrition claims on packaging became one of the most important standards to decide whether to buy. A great deal of research has focused on consumer responses (e.g., Hieke and Taylor 2012; Parker & Lehmann 2014; Shah et al. 2014) to the influx of product information to markets. Topics of research included the impact on consumers’ beliefs with regards to products (Ford et al. 2005), purchasing behavior (Nikolova and Inman 2015), and information processing behavior (Moorman 1990). The diversity of consumer responses is based on consumer differences (Moorman 1990), and health- and nutrition-related (HNR) claims (Choi et al. 2013). Although a great deal of research has addressed the influence of product information disclosure on the market, these studies have focused almost exclusively on developed economies. Going forward it is very likely that emerging markets will play a more important part in corporate strategic planning, as opposed to something considered after making plans for long developed markets. Thus, the impact of market information is likely to matter more and more to those global marketers operating in emerging markets. To fill the research gaps, we investigated how the existence and forms of nutrition claims affect the purchase intention of consumers in China. We explore the moderating role of consumer’s nutrition knowledge. We combine simulation experiment and questionnaire and design two experiments: Experiment 1 is about the existence of nutrition claims, we want to know how the existence of nutrition claims affects the purchase intention of consumers. Experiment 2 which is 2(health claims Vs function claims)×2 (promotion Vs prevention) test is to find out how the claim presentation forms impact the purchase intention of consumers. In experiment 1, we required the subjects to choose one setting randomly and fill in the questionnaires according to their choices. We collected 315 effective questionnaires of experiment 1and 156 effective questionnaires of experiment 2. The results show that: (1) The existence of nutrition claims affects the purchase intention of consumers. specifically, compared with the product without health claims, consumers tend to choose the one with health claims, and compared with the product without function claims, consumers tend to choose the one with health claims.(2)Nutrition knowledge plays a positively role. Nutrition knowledge can change the effect of the existence of health claims and function claims on purchase intention.(3) Consumer trust only plays a partly moderate role. The consumer trust can increase the effect of the existence of function claims but not health claims on purchase intention.(4)The forms of nutrition claims affect consumers purchase intention. Consumers tend to choose the product with promotion claims more than the one with prevention claims.(5) Nutrition knowledge plays a positively role, it can improve the effect of the forms of health claims on purchase intention. The more nutritional knowledge does consumers comprehend, the more sensitive to the product with promotion claims they are.(6)Consumer trust also plays a positively role. The higher Consumer trust does consumers maintain, the more sensitive to the product with promotion claims they are.

유정문(Liu Jingwen),강석민(Kang, Seok-Min),원정연(Won, Chung-Yeon) 대한건축학회 2021 대한건축학회 학술발표대회 논문집 Vol.41 No.2

This paper evaluates the effectiveness of daylighting on the south elevation of small-scale buildings located in Seoul under the influence of the “Diagonal Plane Restriction” policy. South Korea’s ‘Diagonal Plane Restriction’ has long been a controversial policy since the 70s for its limited effectiveness and causing inefficient land use. This paper analyzes the characteristics of selected sample buildings in blocks located near Anam and Sadang subway stations. First, buildings were classified based on the location of the core inside. Then, the effectiveness of the “Diagonal Plane Restriction” policy was evaluated by analyzing the proportion of windows for occupied spaces on south elevations of the identified types.

대학건축물 외피의 지속가능한 레트로피트 전략에 관한 예비 연구 - 국내 사례의 유형 분석을 중심으로 -

유정문(Liu Jingwen),원정연(Won, Chung-Yeon) 대한건축학회 2023 대한건축학회 학술발표대회 논문집 Vol.43 No.2

For several decades, limited materials and systems were used for facade finishes for institutional buildings in South Korea, driven by economic, cultural, and legal considerations. However, the extensive use of paint, tiles, and face bricks has led to significant deterioration, creating safety hazards and aesthetic problems. The objective of this study is to analyze the wall systems and finishing materials of 26 university buildings in Seoul and identify the generalized relationships between typological variations and retrofitting approaches. This study provides reliable sample support for subsequent research analyzing Embodied Energy (EE) and Life Cycle Cost (LCC). Ultimately, the study aims to present a sustainable and optimal architectural design guide for the retrofitting of facades in aging institutional buildings.

Fuchen Liu,Zonglai Liang,Jingwen Xu,Wei Liu,Dandan Zhao,Yuying Zhao,Chuanzhu Yan 대한신경과학회 2016 Journal of Clinical Neurology Vol.12 No.3

Background and PurposezzTe wnt/β-catenin signaling pathway plays a critical role in embryonic development and adult-tissue homeostasis. Recent investigations implicate the importance of wnt/β-catenin signaling in normal wound healing and its sustained activation being associated with fbrogenesis. We investigated the immunolocalization and activation of wnt/β-catenin in polymyositis (PM), dermatomyositis (DM), and Duchenne muscular dystrophy (DMD). MethodszzImmunofuorescence staining and Western blot analysis of β-catenin were performed in muscle specimens from 6 PM, 8 DM, and 6 DMD subjects. Te β-catenin/Tcf4 DNA-binding activity in muscle was studied using an electrophoretic mobility shif assay (EMSA), and serum wnt/β-catenin/Tcf transcriptional activity was measured using a luciferase reporter gene assay. ResultszzImmunoreactivity for β-catenin was found in the cytoplasm and nuclei of muscle fbers in PM, DM, and DMD. Te protein level of β-catenin was elevated, and EMSA analysis confrmed the activation of wnt/β-catenin signaling. Te transcriptional activities of β-catenin/ Tcf in the circulation were increased in patients with PM, DM, and DMD, especially in those with interstitial lung disease, and these transcriptional activities decreased when PM or DM patients exhibited obvious clinical improvements. ConclusionszzOur fndings indicate that wnt/β-catenin signaling is activated in PM, DM, and DMD. Its activation in muscle tissue and the circulation may play a role in modulating muscle regeneration and be at least partly involved in the process of muscle and pulmonary fbrosis.

Liu Zhang,Jiakun Zhang,Jingwen Lei,Yutong Xu,Xue-Ying Lv 한국광학회 2022 Current Optics and Photonics Vol.6 No.4

In this paper, the details and design process of an optical system for space target detection cameras are introduced. The whole system is divided into three structures. The first structure is a short-focus vis-ible light system for rough detection in a large field of view. The field of view is 2°, the effective focallength is 1,125 mm, and the F-number is 3.83. The second structure is a telephoto visible light systemfor precise detection in a small field of view. The field of view is 1°, the effective focal length is 2,300mm, and the F-number is 7.67. The third structure is an infrared light detection system. The field ofview is 2°, the effective focal length is 390 mm, and the F-number is 1.3. The visible long-focus narrowfield of view and visible short-focus wide field of view are switched through a turning mirror. Design results show that the modulation transfer functions of the three structures of the system are close to the diffraction limit. It can further be seen that the short-focus wide-field-of-view distortion is controlledwithin 0.1%, the long-focus narrow-field-of-view distortion within 0.5%, and the infrared subsystem distortion within 0.2%. The imaging effect is good and the purpose of the design is achieved.

Quan Liu,Lu Zhang,Xiuru Ji,Meong Cheol Shin,Shuping Xie,Baoyan Pan,Fei Yu,Jingwen Zhao,Victor C. Yang 한국공업화학회 2020 Journal of Industrial and Engineering Chemistry Vol.89 No.-

Ribosome-inactivating proteins (RIPs) are potent protein toxins for cancer therapy, and they have strongability to inhibit protein synthesis and induce cell death via inactivation of ribosomes in eukaryotic cells. However, the delivery of RIPs has been a challenging task due to their large molecular weight and lack oftargeting property. Low molecular weight protamine (LMWP), a transmembrane peptide, has beenproved to effectively promote transmembrane transportation, whereas the enzyme-activatable systemcan enhance the specificity by enhancing the tumor drug concentration through enzymatic reaction. Weherein constructed a self-assembly and stimuli-responsive fusion gelonin delivery system. Gelonin, atypical RIP protein, was assembled with nickel ferrite nanoparticles by self-assembling between hexa-histidine tag (His-tagged) and nickel ions. Both in vitro and in vivo results indicated that the magneticnanoparticle carriers and the applied linkers did not damage the pharmaceutical effect of gelonin, andthe whole drug delivery system showed good biocompatibility, sensitive selectivity, and significantlyenhanced cytotoxic activity. This in turn presented theranostic nanoparticles as efficient delivery vehiclefor clinical use.
