The present study explored how 1) individuals' perception about attributes of exercise/fitness apps and 2) their motivation for exercise/fitness behaviors influence perceived usefulness and usage of the apps. A survey of 323 males and females in their 20's and 30's revealed that attributes of apps that satisfy their basic psychological needs are crucial in promoting perceived usefulness and usage of the apps. Participants were more likely to perceive exercise/fitness apps useful as they perceive them having more attributes related to autonomy and competence. The perception regarding relatedness attributes did not have the main effect on perceived usefulness but showed an interaction effect with relative autonomous motivation. This convergence study which examined health apps from the perspectives of psychology and public health provides practical implications to development and evaluation of health apps.

Behavior awareness is a technology that recognizes human behavior through data and can be used in applications such as risk behavior through video surveillance systems. Conventional behavior recognition algorithms have been performed using the 2D camera image device or multi-mode sensor or multi-view or 3D equipment. When two-dimensional data was used, the recognition rate was low in the behavior recognition of the three-dimensional space, and other methods were difficult due to the complicated equipment configuration and the expensive additional equipment. In this paper, we propose a method of recognizing human behavior using only CCTV images without additional equipment using only RGB and depth information. First, the skeleton extraction algorithm is applied to extract points of joints and body parts. We apply the equations to transform the vector including the displacement vector and the relational vector, and study the continuous vector data through the RNN model. As a result of applying the learned model to various data sets and confirming the accuracy of the behavior recognition, the performance similar to that of the existing algorithm using the 3D information can be verified only by the 2D information.

Party is the main factor in modern country. Therefore, there are a lot of articles about the difference of public policies and citizen's recognition according to their supported party. However, there is few research about the regulation recognition according to citizen's supported party. This study focuses on the differences of a regulation recognition according to citizen's supported party. In result, there are a lot of differences of regulation recognition according to citizen's supported party. The people who support Saenuri Party have a positive recognition about a necessity of regulation, a fairness of regulation, a reliability of a regulation. But the people who don't support Saenuri Party have a negative recognition about those. In Korea, government regulations have a lot of relationship with a party and politics.

The main characters play leading roles in novels. In the previous studies, they recognize the main characters in a novel mainly based on dictionaries that built beforehand. In English, names begin with upper cases and are used with some words. In this paper, we propose a recognition method for main characters name in Korean novels by using predicates, rules and weights. We first recognize candidates for the characters name by predicates and propose some rules to exclude candidates that cannot be characters. We assign importances for candidates, considering weights that given by the number of candidates appeared in a sentence. Finally, if the importance of the character is more than a threshold, we decide that the character is one of main characters. The results from the experiments for 300 novels show that an average accuracy is 85.97%. The main characters name may be used to grasp relationships among characters, character's action and tendency.

This study attempts to explore factors that influence the perception of importance of information security. Three possible exogenous variables including perceived certainty of punishment, perceived response cost, and acquiescense are suggested that are based on the protectiom motivation theory. As a result, we found followings. First, The perceived punishment certainty has a significant effect on the perceived importance of information security. Also, it influences a negative effect on acquiescence. Second, the response cost has a negative effect on the perceived importance of information security. In addition, the response cost positively effects on acquiescence. Finally, acquiescence negatively influences on the perceived importance of information security. The results show that, in order to increase the perceived importance of information security among employees, it is necessary to make them aware that a security violation can result in certain punishment. At the same time, organizations should also attempt to remove major obstacles accompanying security behaviors of employees. Finally, organizations encourage open communication relating to information security among employees.

혁신의 정의는 연구 관점과 범위에 따라 상이하게 정의되고 있다. 다양한 학문 분야의 혁신 연구를 종합하여 혁신 확산 이론을 체계적으로 정립한 Rogers(1995)는 혁신을 "채택하여 활용하는 개인이나 조직이 새로운 것으로 인식하는 아이디어, 행위, 개체 (An idea, practice, or object that is perceived as new by an individual or other unit of adoption)"로 정의하고 있다. 한편 Becker ＆ Whisler(1967)은 혁신을 "대상 모집단 중에서 특정 아이디어를 최초로 혹은 초기에 사용하는 것 (the first or early use of an idea by one of a set of organizations with similar goals)"으로 정의하였다.(중략))"으로 정의하였다.(중략).(중략)

최근 기업들은 인적·물적 손실, 수입감소, 배상책임 등의 위기에 직면하고 있다 실제 경영에서는 가시적으로 나타나고 있지 않으나, SHE(Safety of Health & environment)과 이상기후 및 기상변동에 의한 대형사고, 자연재해가 증가하고 있다. 각종 대형사고, 공해문제, 소비자문제 등은 기업의 내·외에서 발생하고 있는 문제들이 기업의 부도덕한 행위로 인식되면서 기업의 사회적 책임을 묻는 사례는 증가하고 있는 실정이다. 이러한 결과는 기업에 대한 부정적 국민의식과 함께 사소한 일이라도 쟁의 소송으로 발전하거나 단순한 종업원 개인이 기업외부에서 일으킨 사고까지 기업이미지와 직결되고 있다(중략)

학동기는 급격한 성장과 생체 기관의 기능이 충실해지는 동시에 내분비계의 발달로 성적 성숙이 완료되는 영양필요량이 급증하는 시기이다. 또한 자아존중감이 형성되고 식사에 대한 태도와 인식, 또한 반복적인 행위가 습관으로 굳어지는 시기로서, 바른 식태도와 식기호도, 식습관의 형성이 무엇보다도 중요한 시기이다. 현재 우리나라는 10,000여개에 이르는 전국의 초ㆍ중ㆍ고등학교에서 학교급식이 시행되고 있으며, 2006년 영양교사 배치를 눈앞에 두고 있다. 따라서 학교급식의 위생 및 영양관리를 통한 질적 향상과 더불어 학생의 영양 및 식생활 향상을 위한 식생활지도의 필요성이 급증하고 있다.(중략)

최근에 온라인 학습 시스템으로서 다양한 학습 컨텐츠를 갖고 있는 새로운 교수 모형이 제시되고 있다. 또한, 학습자의 요구에 따른 코스웨어의 주문이 증가되고 있는 추세이며 그에 따라 웹 기반 교육 시스템에 효율적이고 자동화된 교육 시스템의 필요성이 인식되고 있다. 본 논문은 이러한 웹기반 교육 시스템에서의 개별 학습자들에게 차별적으로 개인화된 학습 자료를 제공하므로서 보다 효과적이고 효율적으로 학습에 임할 수 있도록 개인화된 학습자료 생성 시스템을 제안한다. 이는 개별 학습자들의 학습 행위에 따른 이벤트를 검출하여 데이터베이스화 시킨 후 이를 이용하여 학습 자료 선호도를 계산함으로써 개인화된 학습 자료를 생성하는 시스템이다.

전략적 제휴는 이제 흔히 볼 수 있는 기업의 경영전략이 되었다. 기존의 규제당국의 전통적 입장에 의하면 전략적 제휴는 관련시장에서의 경쟁을 제한할 우려가 있는 부당한 공동행위로 간주될 가능성이 많았다. 그러나 전략적 제휴의 장점들이 인식되면서 이에 대한 규제당국의 입장이 변화되고 있다. 본 고는 이러한 변화 추세를 규범적 관점에서 분석하였다.
