  • 많은 과학자들은 인간의 사고를 functional Magnetic Resonance Imaging (fMRI), Time Resolved Spectroscopy(TRS), Electroencephalography(EEG)등을 이용해서 두뇌 활동 영역을 연구하고 있다. 주로 의학 분야와 심리학의 영역에서 두뇌의 활동을 연구하여 간질이나 발작을 알아내고 거짓말 탐지 분야에서도 사용된다. 본 논문에서는 사람의 두뇌활동을 측정하여 인간의 감정을 인식하는 연구에 중점을 두었다. 특히 fMRI와 TRS 그리고 EEG를 이용해서 사람의 두뇌활동을 측정하는 연구를 하였다. 많은 연구자들이 한 가지 측정 장치만을 사용하여서 측정하거나 fMRI와 EEG를 동시에 측정하는 연구를 진행하고 있다. 현재에는 단순히 두뇌의 활동을 측정하거나 측정시 발생하는 잡음들을 제거하는 연구들에 중점을 두고 진행되고 있다. 본 연구에서는 fMRI와 TRS를 동시에 측정하여 얻은 두뇌 활동 데이터를 가지고 감정에 따른 활동영역의 EEG신호를 측정하였다. EEG 신호분석에 있어서 기존의 뇌파만을 가지고 특정을 찾아내는 것을 넘어서 각각의 채널에서 기록되는 뇌파의 파형을 주파수에 따라서 분류하고 정확한 측정을 위해 낮은 주파수를 제거하고 연구자가 필요한 부분의 뇌파를 분석하였다.

  • The purpose of this study is to present a framework for sales activities necessary for the successful sales development in the sales process of value-based selling and to explore individual sales activities for successful value-based selling. When we understand value-based selling as a procedural progression in the sales process, integrate it into the sales activity framework, and segment your sales activities to identify the key activity elements for successful execution, the intrinsic effect of value-based selling can be achieved. Sales activities related to the success of value-based selling are reflected in the sales activity framework based on the sales process through literature studies and application cases in actual sales field, and detailed elements of individual sales activities for successful deployment are identified through case studies. Through literature research and sales practice in actual field, 13 sales activities are presented in the five-stage sales process, and 42 detailed sales activities for successful value-based selling through case studies are identified in an improved sales activity framework. Through this study, the sales activity framework provides a role in evaluating whether the sales function of value-based selling is being performed as a correct activity in the sales process, and whether sales opportunities with specific customers can continue value-based selling activities. The sales activity framework serves as a guide for successful value-based selling.

  • The purpose of this study is to analyze the effect of youth activities on adolescents' sense of community using "Korean Children & Youth Panel Study" data collected by the National Youth Policy Institute. Especially, this study tried to reflect various aspects of youth activities, such as participation in activities, number of types of activities, and satisfaction with activities. Also, this study paid particular attention to examining the cumulative effect of youth activities. The main results are as follows. First, the participation of youth activities, the satisfaction level of experiential activities, and the number of kinds of experiential activities varied according to income level and regional scale. Next, the results of the OLS regression analysis on adolescents' sense of community show that participation in youth activities, number of kinds of activities that participated in, and satisfaction with activities during the first-year of high-school all influence adolescents' sense of community. On the other hand, the results of analysis of the effects of cumulative experience during middle school during middle school shows that it is difficult to ensure long-term effects by only participating in youth activities. Positive effects persisted only when adolescents participated in high quality youth activities during middle school. The results of this study show that the qualitative aspects of youth activities are important for sustaining the effectiveness of youth activities.

  • Activity theory explains that the old people participate in social activity as a role-substitute from loss of roles given by work and family. It is possible to enhance their life satisfaction through these activities. Based on this activity theory, this study aims at explore the role substitute of voluntary activities and to analysis whether volunteering commitment has an effect on life satisfaction. Data were collected by using survey questionnaires to the elderly over 55 years old who participated in voluntary activity at 25 Volunteer Centers in Seoul. The Activity theory was operationalized by job or joblessness, family type, achievement type obtained through voluntary activity The results are as follows. (1) Job or joblessness has effect on the activity frequence and activity time. (2) Social achievement after voluntary activity has effect on the duration only (3) And the family type did not have any effect. These three variables of activity theory do not have an effect on life satisfaction. The elderly volunteering commitment was explained by variables other than activity theory such as reward, health, education, sex. And the elderly volunteer's life satisfaction were affected by the family types and their economic status. These results imply that the Korean elderly voluntary activities could be expained partially by Activity theory. Also for these elder volunteers's life satisfaction, qualitative respects such as achievements through voluntary activity, and concerns and support by agencies are more important than the time they imput in voluntary activities.

  • This study conducts statistical analysis based on a survey of 300 CEOs from Korean companies in order to examine the effects of a CEO's internal?external activities (information, knowledge management, learning organization) on business innovation activity (exploitative, exploratory) and business performance. Analysis results show that learning organization activity had a significant positive (+) effect on exploitative and exploratory innovation activity. In addition, knowledge management activity lacked statistically significant effects on exploratory innovation activity. Furthermore, exploitative and exploratory innovation activity was affected by CEO's internal?external activities (information, knowledge management, learning organization) and had a significant positive (+) effect on company's business performance. but it was shown that the level of influence was different. Results of this study imply that maximizing business performance through developing innovation activity by CEO's internal?external activities (information, knowledge management, learning organization) in the company, extracting activity advantageous to company's business environment based on activity perceived in the precedent study and business strategy becomes advantageous to the attainment of business performance objectives.
