Visible light communication is a communication method using light, and it has advantage of ensuring security in a single space as compared with RF communication. However, in the area outside the visible line of the light, communication disconnection occurs. Therefore, this paper proposes a relay module to overcome the coverage extension and communication disconnection phenomenon of visible light communication. The proposed relay module transmits and receives data of visible light communication by sequentially transmitting data packets including target ID through adjacent visible light module. Through experimentation of data transmission, we confirmed the extension of the transmission range and the data reception in the area outside the line of sight.

Purpose - This study presents the relationships between parent brand-self image congruence, parent brand -functional congruity, perceived fit between parent brand and extension product, and consumer's attitude toward extension product using the structural equation model. As for preceding concepts having a direct effect on consumer's attitude toward brand extension, the study focuses on parent brand-self image congruence and parent brand-functional congruity. It also looks at the effect of parent brand-self image congruence and parent brand-functional congruity on the consumer's attitude toward extension product and identifies if the perceived fit between parent brand and extension product is a concept playing a mediating role between parent brand-self image congruence or parent brand-functional congruity and consumer's attitude toward brand extension product. Research design, data, and Methodology - SPSS for Windows 18.0 and AMOS 18.0 were used for data analysis. Then, the Cronbach's α coefficient was obtained using SPSS for Windows 18.0 to measure reliability. In addition, the convergence and discriminative measures of the measured items were statistically verified using AMOS 18.0. Finally, we have validated a path model and a parameter model in which brand personality-self-matched attitude toward brand extension. Results - Studies have shown that the impact of parent brand-self image consistency and parent brand-functional consistency on the attitude of extended products was positive. Perceived fit between parent brand and extension products has been shown to play a role of intermediary between parent brand-self image congruence and consumer attitudes to extended products. However, perceived fit between parent brand and extension products did not play a role as intermediary between the parent brand-functional congruity and the attitude toward the extended product. Finally, in relation to the causal relationship between parent brand-congruity (self image/functionality) and attitudes to extended products. The effect of parent brand-functional coherency on attitudes toward extended products was found to be greater in groups with higher involvement than in those with lower involvement. Conclusions - Although few studies have been done on what variables mediated when parent brand-self image consistency and parent brand-functional coherency affect consumer attitude, this paper is significant in finding whether perceived fitness between the parent brand-congruity and the extension product is mediated.

Recently, some fashion retailers have initiated sustainable actions in the form of corporate social responsibility (CSR) activities to address consumers' social concerns. This study intends to combine the concept of CSR motivation attributions with brand extension literature in order to examine how consumers' trust of a parent brand affects their CSR motivation attributions and ultimately their attitudes towards parent-brand CSR activities and sustainable extension lines. A self-administered online survey was conducted using scenarios describing a fast fashion retailer introducing a sustainable line. Data from 303 female U.S. consumers, aged between 18 and 34 years, were used for the statistical analysis. Data analyses were conducted using SPSS 21.0 for descriptive analysis, exploratory factor analysis, and regression analysis. The results revealed that all hypotheses were supported. The findings show that consumers' trust of a parent brand has an indirect impact on positive attitudes towards the parent brand's CSR activities as well as the sustainable extension product line, mediating positive evaluations of the brand's social CSR motivations. In addition, this study suggests consumers' prior trust of the parent brand is a variable that affects consumers' evaluation of CSR motivation sincerity. Marketing suggestions and thoughts based on the findings of this study were provided.

Seakso 5, a maize hybrid, was applied for variety in 2021 by Gangwon Agricultural Research and Extension Services in Korea. This variety was bred to produce a purple extract of com husk. It shows purple color in the husk and cob and contains abundant anthocyanins. In this study, to obtain basic data on purple com 'Seakso 5' husk extract (PCHE), a husk extract was prepared and the contents of vitamins, amino acids and fatty acids were analyzed. The Seakso 5 husks were extracted with 30% alcohol and concentrated, after adding dextrin to the concentrate, it was spray-dried to prepare an extract. The PCHE were analyzed for vitamins, amino acids, and fatty acids by referring to the Food Code. As a result, three types of vitamins were detected, and their contents were vitamin B₁ 0.14 mg/100g, vitamin B₂ 2.30 mg/100g, and vitamin C 11.32 mg/100g. A total of 15 amino acids were detected in the PCHE, including aspartic acid and glutamic acid, and the content of aspartic acid was the highest at 3.02 mg/g. Simultaneous analysis of fatty acids Among 37 types, saturated fatty acids were palmitic acid (C16:0), stearic acid (C18:0), monounsaturated fatty acids were oleic acid (C18:1(n-9)), polyunsaturated fatty acids were linoleic acid(C18:2(n-6)c) and a-Linolenic Acid (C18:3(n-3)) were detected. Among the detected fatty acids, the content of palmitic acid was the highest at 40.75 mg/100g. In the future, These analysis results will be used as reference data for temporary food ingredient applications by the Ministry of Food and Drug Safety.

The purpose of this study was to investigate the effect of attitude towards parent brand on extended fashion products in case of fashion brand extension. The subjects of this study were 386 college students and data were collected using survey questionnaire. For data analysis, factor analysis and path analysis were applied. The results showed that there were four factors (e.g., familiarity attitude, emotional attitude, value-expressive attitude, utility information attitude) in attitude towards parent brand and six factors (e.g., economical risk, utilitarian risk, social risk, psychological risk, time/advantage loss risk, risk for losing opportunity) under perceived risk in extended product. The results showed that attitude towards parent brand had a negative effect on perceived risk in extended products and had a positive effect on attitude towards extended products. Perceived risk in extended products then had a negative effect on purchase intention of extended products whereas attitude towards extended products had a positive effect on purchase intention of extended products.

For an off-site consequence analysis at nuclear power plant, MELCOR Accident Consequence Code System(MACCS) II code is widely used as a software tool. In this study, the algorithm of web-based off-site consequence analysis program(OSCAP) using the MACCS II code was developed for an Integrated Leak Rate Test (ILRT) interval extension and Level 3 probabilistic safety assessment(PSA), and verification and validation(V&V) of the program was performed. The main input data for the MACCS II code are meteorological, population distribution and source term information. However, it requires lots of time and efforts to generate the main input data for an off-site consequence analysis using the MACCS II code. For example, the meteorological data are collected from each nuclear power site in real time, but the formats of the raw data collected are different from each site. To reduce the efforts and time for risk assessments, the web-based OSCAP has an automatic processing module which converts the format of the raw data collected from each site to the input data format of the MACCS II code. The program also provides an automatic function of converting the latest population data from Statistics Korea, the National Statistical Office, to the population distribution input data format of the MACCS II code. For the source term data, the program includes the release fraction of each source term category resulting from modular accident analysis program(MAAP) code analysis and the core inventory data from ORIGEN. These analysis results of each plant in Korea are stored in a database module of the web-based OSCAP, so the user can select the defaulted source term data of each plant without handling source term input data.

This study was carried out to provide basic data for spreading rice direct seeding by inducing stabilization of seedlings, yield and quality according to sowing times in rice direct seeding cultivation. In 2016, 'Sukwang' was seeded 3 times by 10 days interval on May. 10, 20, 30 and 6kg/10ha of seeding rate respectively in Iksan. In summary, the number of rice seedling establishment was higher than the optimum seedling establishment level at all sowing periods and the seeding rate was better as the sowing period was delayed. Weed development by sowing was the highest at early sowing, May 10, and decreased at late sowing. Heading dates were delayed by 3days for sowing on May 10, 7days for sowing on May 20, and 11 days on sowing on May 30. Rice yield increased with the delay sowing time and compared to the transplanting. It was 84% in sowing on May 10, 94% in sowing on May 20, and 99% in sowing on May 30. In addition, head rice ratio and head rice yield increased according to delayed of seedling.

Purpose - This study examines the strength of sadness and the belief it will last, as regards the effects of the degree of self-extension to the sad-evoking event on choice behavior related to self-control dilemmas. Research Design, Data, and Methodology - In an experiment involving high and low self-extension groups, 261 undergraduates answered self-administered questionnaires. The hypotheses were tested using AMOS 19.0 and path analysis. Results - The positive relationship between the degree of self-extension to the sad-evoking event and hedonic vs. utilitarian food choices was mediated by the belief that the sadness will last. There is a significant indirect path from the degree of self-extension (to the sad-evoking event) to the strength of the sadness, and to the belief that it will last with respect to hedonic vs. utilitarian food choices. Conclusions - These results show that beliefs about sad emotion transience depend on both the degree of self-extension to the sad-evoking event and the strength of sadness, and that the belief that sad emotions are transient makes sad people susceptible to temptation when facing self-control related dilemmas.
