Purpose - Electrical energy saving is one of the practical virtues relating to sustainable living. Therefore, policy-makers has tried to find a way to change the behaviors of individuals to encourage them to actively practice electrical energy saving, even if they have never had this concern or have only passively practiced electrical energy saving to this point. Prior research related to electrical energy saving can be categorized into several types. The first is focused on consumer characteristics linked to electrical energy saving. These studies are based on individual or household socio-demographic variables (e.g., age, gender, household income, education level, occupants, marital status, number of households), and psycho-graphics (e.g., environmental consciousness, value, attitude, motivation, lifestyle). The second is focused on policies (e.g., monetary incentives, information sharing, social comparison, feedback), and technologies (e.g., energy-efficiency home appliances, energy-reduced products, renewable resources). People generally have a favorable attitude towards electrical energy saving, while electrical energy saving practices tend to be less favorable. Therefore, it is necessary for policy-makers to seek out gaps between attitudes and behaviors and find alternatives to reduce these gaps. This study investigates the influence of authenticity on the behavioral intention of electrical energy saving. It is supposed that electrical energy saving practices are likely to be stronger as authenticity of individual or household becomes stronger. This study reviews prior literature and examines various studies to provide an understanding of the relationships between authenticity and electrical energy saving behavioral intention. Research design, data, and methodology - Hypothesis was drawn from analysis based on previous research. The items related to authenticity and electrical energy saving were selected from items found in previous research. To verify this hypothesis, data were collected via experimental survey method and the resulting data were analyzed using reliability analysis, correlation analysis, and hierarchical regression analysis. Results - This study found that authenticity had a positive impact on the behavioral intention of electrical energy saving. The higher the perceived degree of authenticity, the higher the behavioral intention of electrical energy saving. Conclusions - This study assesses the impact of authenticity on the behavioral intention of electrical energy saving. In order to enhance the practice of electrical energy saving, it is efficient strategy for policy-maker to improve the perceived authenticity of individuals.

[Introduction] Nowadays, many companies are shifting their businesses online due to the growing trend among customers to buy and shop online, as people prefer online purchasing products. [Problem] Users share a vast amount of information about products, making it difficult and challenging for the end-users to make certain decisions. [Motivation] Therefore, we need a mechanism to automatically analyze end-user opinions, thoughts, or feelings in the social media platform about the products that might be useful for the customers to make or change their decisions about buying or purchasing specific products. [Proposed Solution] For this purpose, we proposed an automated SentiDecpective approach, which classifies end-user reviews into negative, positive, and neutral sentiments and identifies deceptive crowd-users rating information in the social media platform to help the user in decision-making. [Methodology] For this purpose, we first collected 11781 end-users comments from the Amazon store and Flipkart web application covering distant products, such as watches, mobile, shoes, clothes, and perfumes. Next, we develop a coding guideline used as a base for the comments annotation process. We then applied the content analysis approach and existing VADER library to annotate the end-user comments in the data set with the identified codes, which results in a labelled data set used as an input to the machine learning classifiers. Finally, we applied the sentiment analysis approach to identify the end-users opinions and overcome the deceptive rating information in the social media platforms by first preprocessing the input data to remove the irrelevant (stop words, special characters, etc.) data from the dataset, employing two standard resampling approaches to balance the data set, i-e, oversampling, and under-sampling, extract different features (TF-IDF and BOW) from the textual data in the data set and then train & test the machine learning algorithms by applying a standard cross-validation approach (KFold and Shuffle Split). [Results/Outcomes] Furthermore, to support our research study, we developed an automated tool that automatically analyzes each customer feedback and displays the collective sentiments of customers about a specific product with the help of a graph, which helps customers to make certain decisions. In a nutshell, our proposed sentiments approach produces good results when identifying the customer sentiments from the online user feedbacks, i-e, obtained an average 94.01% precision, 93.69% recall, and 93.81% F-measure value for classifying positive sentiments.

Previous studies on the effects of speaking rate on voice onset time (VOT) of stops in English, French, Icelandic, and Thai indicate that speaking rate asymmetrically affects VOT values. That is, pre-voiced and long-lag stops vary due to the rate factor more than short-lag stops do. One suggested explanation for this asymmetry is that it is due to the necessity of maintaining phonetic contrasts among the stop categories. Since pre-voiced and long-lag stops represent the ends of the VOT scale, they encompass broad swathes of that range and consequently allow for large variations. On the other hand, the VOT variations of short-lag stops may result in overlap with the VOTs of long-lag stops. This study aimed to explore the effects of speaking rate on the VOTs of Korean stops and see whether Korean fortis and lenis stops are limited in the degrees of variation as a function of rates due to the existence of stops with larger VOT values, lenis and aspirated stops respectively. Conversely, aspirated stops were expected to show more variation since there are no other categories with longer VOTs. Fortis, lenis, and aspirated stops in /CVn/ words (C = bilabial or velar stop, V = /i/ or /a/) were examined in isolation, and at normal and fast rates in a carrier sentence. Speaking rates were controlled by alternating words or sentences on a computer screen at intervals of two seconds for the isolation- and normal-rate conditions and one second for the fast-rate condition. This study found that while the VOTs of fortis stops did not change significantly, those of lenis and aspirated stops showed considerable changes as a function of speaking rates. Also, overlap between lenis and aspirated stops occurred considerably at all speaking rates. These phenomena were interpreted to relate to the fact that VOT contrasts between lenis and aspirated stops in Korean are currently being collapsed. Large variations of lenis stops as a function of rates seem to occur due to a weak motivation to limit the degree of variations for the purpose of maintaining phonetic contrasts. The significant overlap between lenis and aspirated stops at all rates was interpreted to occur because the VOT merger between the two categories became considerably fixed. Also the percentage of correctly-classified VOTs by optimal-boundary values between lenis and aspirated stops turned out to be lower than in previously-studied languages. This was interpreted to be further evidence that VOTs are losing their role in contrasting the two stop categories in Korean.

The goal-gradient hypothesis states that the tendency to approach a goal increases with the increasing proximity of the goal (Hull 1932). It was initially supported with an evidence of animal experiments and since then, several papers have investigated the goal-gradient hypothesis in humans. Although there are some evidences related to the goal-gradient hypothesis in human behaviors, none of previous studies can properly explain its underlying mechanism, and what's more, they were not able to suggest useful managerial applications in human behaviors. From these perspectives, this work points out that there are some theoretical weaknesses to apply the goal-gradient hypothesis into the complicated human decision-making behaviors and proposes an alternative theoretical mechanismthat underlies the goal-gradient hypothesis in human. Finally, it offers insights into managerial implications of the goal-gradient hypothesis in the marketing field. This study focuses on the changes in motivations for achieving goals, in terms of how approaches to goals vary according to temporal distance from those goals. Specifically, the temporal construal theory (Liberman and Trope 1998) is considered as the underlying mechanism of the goal-gradient in that the temporal construal theory argues how the temporal distance from a goal makes people change their associated values regarding to that goal. According to the temporal construal theory, the value of distant future outcomes (near future outcomes) is construed on the basis of abstract and central features (concrete and peripheral features), and it argues that distant future situations are construed on a higher level than near future situations. This means that the value associated with the high-level construal is enhanced over delay, whereas the value associated with the low-level construal is discounted over delay. Our propositions suggest that the goal-gradient behavior in human can be motivated by the different aspects or characteristics of the goal as time changes based on the temporal construal theory. Thus, the following propositions are proposed. P 1-1: If the goal is far away, consumers put more value on the central features that are more associated with the desirability of the goal. P 1-2: If the goal is far away, consumers put more effort into accomplishing the goal that has more central features, regardless of its peripheral features. P 2-1: If a goal is near, consumers put more value on the peripheral features that are more associated with the feasibility of the goal. P 2-2: If a goal is near, consumers put more effort into accomplishing the goal that has more peripheral features, regardless of its central features. We hope to provide sufficient managerial implications for the companies as our research aims to show how consumers react differently as they progress toward the goal. Proposed propositions may provide guidance for companies developing a loyalty program, enabling them to understand what kinds of benefits or services they should provide or emphasize to consumers in loyalty programs on the basis of the time-dependent changes in outcome values (such as gifts, reward coupons). The effects of temporal distance from a goal should inform companies' marketing activities and help themto determine where emphasis should be placed in designing the benefits of their loyalty program.

Objectives : The study has three aims: 1) to assess the perceptions, attitudes, and behaviors of dental hygiene students and other college students towards oral and dental care, 2) to provide grounds for developing an oral and dental health educational program, and 3) to improve the oral and dental health status among the college student population. Methods : The subjects in this study were 520 students who included dental hygiene students from J health college and other majors from a four-year university located in Seoul. The survey was conducted from September, 2010, to June 3, 2011. The collected 507 questionnaires were analyzed. The collected data were analyzed by the statistical package SPSS WIN 12.0, and the level of significance was set at 0.05. Results : 1. As for a daily toothbrushing frequency, the largest number of the students brushed their teeth three times a day, and the dental hygiene students did that more often than the other majors(p<0.001). Concerning awareness of the toothbrushing method and the time for the change of the toothbrush, the rolling method was more prevailing among the dental hygiene students than the others(p<0.001). 2. In regard to education experience about the toothbrushing method and satisfaction with the existing toothbrushing method, 64.7% of respondents ever received education about the toothbrushing method(p<0.001). 3. As to scaling experience and gingival bleeding, the dental hygiene students had more scaling experiences(p<0.001), and the other majors who underwent gingival bleeding from time to time outnumbered the dental hygiene students who did(p<0.01). 4. In relation to subjective oral health status, the dental hygiene students found themselves to be in better oral health than the other majors(p<0.001), and the latter had more parts of the mouth in which they didn't feel well than the former(p<0.01). The dental hygiene students were more concerned about their oral health(p<0.001) and felt more uncomfortable in chewing(p<0.05). The other majors felt more uncomfortable in pronunciation(p<0.01). Conclusions : The results of this study indicated that dental hygiene students strongly recognized the importance of knowledge, motivation, and self-care behaviors, and attitudes towards oral health and dental care compared to other college students. It suggested that regular educational programs for the college student population should be implemented to increase their concern for oral and dental issues and to improve their oral and dental health status.

본 논문은 강원도와 만주 일대에서 활동한 여성독립운동가 윤희순이, 항일투쟁 과정에서 현실을 어떻게 인식했으며, 그에 따른 대응은 어떠했는지 살피는 데에 목적이 있다. 윤희순은 시아버지 유홍석과 남편 유제원, 그리고 아들 유돈상까지 3대가 독립운동에 앞장선 집안의 며느리이자 아내이자 어머니였다. 화서학파였던 고흥 유씨 일가는 '위정척사(衛正斥邪)' 사상을 바탕으로 독립운동에 투신했다. 이들은 새로운 세계의 건설보다는 아름다운 과거로의 복귀와 복원을 염원했고, 의병을 일으킨 것 또한 근대적 국민국가 건설을 위해서가 아니라 왕을 중심으로 구축된 기존의 질서를 회복하기 위해서였다. 친정과 시가 모두 화서학파였던 윤희순 역시 그들과 동일한 눈으로 현실을 바라보았고, 적극적으로 의병활동에 참여하게 된 동인 역시 충 효 열과 같은 중세적 가치였다. 특히 집안의 안사람이자 여성으로서의 명확한 자의식을 갖고 있었고, 그것을 바탕으로 현실의 문제에 대응했다. 그녀는 보다 효과적인 독립투쟁을 위해서는 안사람으로 대변되는 여성들의 인식을 변화시키는 것이 중요하다고 판단했다. 이러한 판단 하에 그녀는 '교육'을 통한 '계몽'을 자신의 과제로 인식했고, 이 과정에서 의병가와 포고문 등은 효과적인 수단으로 활용되었다.

최근에는 소프트웨어개발 프로세스나 도구보다는 개인과의 상호작용을 희망하고, 고객은 포괄적인 문서보다는 우선 작동하는 소프트웨어를 희망하며, 개발자는 계약에 대한 협상보다는 고객과의 협력을, 서로가 계획을 고수하기 보다는 변화에 대응하는 것을 더욱 가치 있게 생각한다. 이러한 관점에서, 소프트웨어 개발은 프로세스 중심보다는 프로젝트팀에게 자율성과 동기를 부여하고, 열정과 비전 등 인간관계 중심의 관리방식이 요구되고 있다. 최근에 와서 애자일 개발프로세스가 생산성 증대효과, 품질향상, 고객만족 등의 효용성이 입증되면서 프로젝트를 추진 할 때 방법론 선택에 있어, 전문가들에게 주목을 받게 되었다. 시대적 요구와 사용자 요구에 부응하기 위한 방법론 선정과 관련, 본 논문에서는 조직 구성에 있어, 제품 기반의 Cross functional team의 문제점을 해결하고자 제안된 방법론이 Feature Team 모델이며, 이 모델이 Cross functional team을 조직하고, 이 팀이 결과물(프로덕트) 단위가 아니라, 기능단위로 여러 프로덕트에 걸쳐서 개발을 진행하는 모델이라는 점에 대해 조사하였으며, 가치-주도형 애자일 기법을 통해 계획-기반형 모델과 차이점을 제시하였다. 그리고 객체지향모델링을 위해서는 기존의 JAD(joint application development)회의가 목표로 하는 도메인 분석, 요구추출, 모델링과 정리, 검토과정에 있어, UML 구조도와 행동도를 사전에 숙지하고 프로젝트를 진행하도록 제안한다.
