This study analyzed the effects of smart phone using for business on work performance in the field. We classified functional and practical aspects of smart phone affecting employee's work performance through former studies. As independent variables, we selected portability of equipment, rapidity of information and ease of use for functional side, and selected fit to work and subjective norms for practical side. And dependent variable was work performance. We also suggested that innovation resistance would be a moderator. The results showed that the effect of work performance was influenced by portability of equipment and fit to work. However, hypotheses on moderating effects of innovation resistance were not supported. This study made a discrimination in terms of an application phase of smart phone as against former studies. The results of this study will provide practical implications for related enterprises in the field to develop ways of using smart phone as an effective strategy.

스마트폰의 등장은 컴퓨터를 손바닥 안으로 옮기는 혁명을 가져왔으며, 그 혁명은 생활의 편리함과 즐거움을 제공하는 스마트 사회를 선도하고 있지만, 스마트폰 증후군을 포함한 부작용 요소가 과거의 그 어떤 IT 기기들보다 더욱 폭넓고 다양한 형태로 나타나고 있다. 본 논문에서는 스마트폰 이용 목적별로 위험 요인을 중심으로 부작용 유형과 유형별 핵심 이슈를 도출하고 이를 토대로 사회적 영향을 진단하였다. 그리고 진단 결과를 토대로 바람직한 스마트폰 활용에 대한 사회적 이해와 공감대가 형성될 수 있도록 부작용을 최소화하기 위한 대응 방안을 제시하였다. 제시한 대응 방안은 스마트 사회의 창의 협력 소통 오락통의 플랫폼인 스마트폰을 바람직하게 활용하게 함으로써 가시적이고 잠재적인 부작용에 대해 체계적으로 대응할 수 있을 것이다.

As smart phone became popular, its excessive uses cause adverse effects called smart-phone syndrome such as Turtle-neck syndrome in physical side and smart-phone addiction in mental aspects. Turtle-neck syndrome incurred by incorrect posture when you watch smart-phone, which causes a serious health problems. However, these syndromes can be detected by gyro-sensor and timer, and prevented by correcting the posture and halting the function with smart-phone application (App). Thus, this paper proposes App that helps user to realize bad posture and addiction to smart-phone, and to acquire the correct habit by inducing user to stretch neck or to stop operation with warning message. If we tried to adjust bad posture and addiction in using smart-phone through this application, the social losses from smart-phone syndrome would be minimized as a result.

As information and communication technology develops, it brings various benefits to our lives. However, information and communication technology has had various side effects in our lives. Representative side effects include internet addiction, smartphone addiction, copyright violation, personal information infringement, cyber bullying and hacking. Recently, smart phone addiction rate is increasing with the spread of smart devices in Korea. In this study, we analyze the correlation between age group and smartphone addiction. In order to obtain fair and objective results, statistical analysis was performed based on the national statistical data of the National Information Society Agency. The results showed that the infant group and the adult group were correlated with the smartphone addiction rate. In this study, we analyzed the causes of smartphone addiction for different age groups. We also discuss dangers of smartphone addiction for different age groups. In additions, we proposed various ways to prevent and cure smartphone addiction for infants, adults, and senior citizen group. The results of this study are expected to be widely used as a remedy for smartphone addiction and future smartphone addiction research works.

Objectives : As of 2013, South Korea ranked number one in the world in smartphone penetration rate with 67.6%. Unfortunately, with the rise of smart phone use, side effects such as fraud, loss of personal information, identity theft, formation and widening of a mobile information gap, and last, but not least, smart phone addiction, also increased. Methods : Seventh (7th)graders from a girls' junior high school in Seoul, the capital of South Korea, we reevaluated the Smart phone Addiction Proneness Scale (S-scale). Among the 9 students classified as high risk users, 5 were randomly selected for a study group, and the remaining 4 students, meanwhile, were designated as a control group. The study group received Korean medicine music therapy (KMMT) in a total of 8 sessions, each session lasting 50 minutes. Both pre- and post-interventions, the two groups completed the S-scale, Harris and Harris' concentration grid exercise, STAI, and STAXI-K. We analyzed the data by t-test and paired t-test using IBM SPSS Statistics. Results : KMMT had a significant influence on proneness to smart phone addiction (t=3.130, p=.035). KMMT had positive effects on concentration improvement (t=-2.935, p=.043), trait-anxiety symptoms improvement (t=2,992, p=.040), and anger-expression control (t=4.416, p=.012). Conclusions : KMMT had positive, improving effects on trait anxiety and anger expression, which in turn enhanced the improvement of concentration as well as the decrease of smart phone-addiction proneness.

This study defined acceptance of high-tech new product as user's active using the product such as utilizing application software rather than purchasing it. As exploring factors to effect on customer's acceptance, usefulness expectancy was examined from product side and application side. When investigating the exogenous variables to influence on usefulness expectancy from the product side, customer's product knowledge and social influences are put forward to support the hypothesis. From the application side, customer's knowledge about the application and its trust are put to explain usefulness expectancy of the application. Smart phone users were good subjects for this study and most hypotheses were tested using structural equation model and the results are followings. First usefulness expectancy of the product and of application significantly effect on customer's intention to use high-tech new product and also usefulness expectancy of the product positively effects on which of the application. Second customer's perceived knowledge about the product and social influences impact usefulness expectancy of the product. But third customer's perceived trust toward application didn't any positive impact usefulness expectancy of the application. Through the result, there will be several implications. First, from both of side; product and application, customer's usefulness expectancy should be satisfied to be successful in high-tech products market. Second, customer should be Ieant about advantages of the product and knowledge about the application as well, and then trigger their usefulness expectancy.

스마트폰이 주도하는 스마트 혁명은 우리의 일상생활 전반의 패러다임을 변화시키고 있다. 이러한 스마트 혁명은 우리에게 많은 편리성을 제공하고 있지만 반면에 역기능도 나타나고 있다. 특히 미래의 주인공인 청소년들의 과도한 스마트 기기 사용으로 인한 부작용의 우려가 커지고 있다. 본 연구에서는 청소년의 스마트 기기 사용 시간과 스포츠 활동 시간 등이 청소년의 감성지능에 어떠한 영향을 주는지에 대해 실증적으로 분석하였다. 회귀분석 결과 스마트 기기 사용 시간이 감성 지능에 부(-)의 관계로 유의한 영향을 미치는 것으로 나타났으며 스포츠 활동 시간도 감성 지능에 정(+)의 관계로 유의한 영향을 미치는 것으로 나타났다. 추가적인 분석으로 독서량도 감성 지능에 정(+)의 관계로 유의한 영향을 미친다는 결론을 얻었다. 이 연구를 통해 전통적인 활동, 즉 스포츠 활동이나 독서는 청소년의 감성 지능 발전에 도움이 되는 반면, 스마트 기기의 사용은 청소년의 감성 지능 발전에 저해 요인이 된다는 결론을 얻었다.

Objective: Smartphone addiction can cause forward head posture, carpal tunnel syndrome and depression, and anxiety. Various interventions have been proposed to resolve Smartphone addiction. However, research regarding the efficacy of these interventions remains lacking. This study was conducted to investigate the effect of tDCS (Transcranial Direct Current Stimulation) on smartphone addiction solution and stress reduction. Design: A randomized controlled trial. Methods: The participants were divided randomly into two group (tDCS vs. Control). tDCS was applied to 41 adults (22.95±2.76 years). The tDCS group was applied 2 mA, for 13 minutes twice over a 26 minute period (n₁ = 21). The control (n₂ = 20) was not applied after padding and was applied twice for 13 minutes over a 26 minute period. This study was conducted four times a week for a total of four weeks. Results: Smartphone addiction for tDCS showed significant improvement in the results in the S-score (p<0.05, 95% CI: 0.702, 4.922), and the result of heart rate (HR) and skin conductivity (SC) to stress. The tDCS group and control group showed no significant decrese in the results in the HR (p>0.05, 95% CI: -3.390, 8.332), but tDCS group showed significant decrese in the results in the SC (p<0.05, 95% CI: 0.060, 1.343) Conclusions: This study suggected that smartphone addiction treatment and decreses of stress. The use of tDCS will reduce the addiction rate of adults and reduce stress, so that possible side effects in society can be solved.
