This article reports the developmental stability of individual differences in children's attachment qualities with their mothers and the relations between the preschoolers' attachment security to mothers and maternal parenting behavior. 24 infants were observed with mothers in the Strange Situation to assess the infant-mother attachment patterns at 16 months of age. After 3 years, attachment security was assessed using Attachment Q-Set, and the modified IPBI (Iowa Parent Behavior Inventory: Mother Form) was administered to mothers to assess their parenting behavior. Analyses revealed significant differences in children's attachment security scores by infancy attachment patterns. That is 11 of 12 children's attachment to mothers qualities were stable across the 3 year periods. The attachment security scores related positively to the responsive maternal parenting behavior. Changes in child-mother attachment quality over time were related to maternal responsiveness. Collectively, these findings were consistent with predictions from attachment theory.

Purpose: This study aims to understand the relationship between university major satisfaction and job preference according to DISC behavior patterns. Methods: To conduct our evaluation, we surveyed a group of 118 students from the Department of Dental Laboratory Technology at the college of Jinju city from August 31 to September 11, 2020. The collected data was evaluated through frequency analysis, descriptive statistics analysis, one-way ANOVA, and regression analysis. Results: The analysis revealed that the steadiness type had the highest and the dominance type had the lowest major satisfaction level by DISC behavior type. The job preference was different for each DISC behavior type, and higher the preference for stability and development, the higher the degree of satisfaction with the major. Conclusion: These results suggest that DISC behavior type, major satisfaction, and job preference are all related. Therefore, these factors should be considered when implementing career guidance and educational programs for college students.

본 연구는 정보추구행태 모형을 제시하고 있는 기존 논의들을 대상으로 이들의 연구경향들을 개관하고 분석함으로써 향후 정보추구행태 연구의 방향점을 논의하고자 하는 시도이다. 본 연구에서는 기존논의들 을 정보추구행태의 영향요인 모형, 과정모형 스타일/패턴모형의 3가지 연구유형으로 대별하였으며, 이들 모형들을 방법론/이론적 틀, 정보추구 맥락, 연구대상/주제분야, 모형 특색 등 9가지 측면에서 분석하였다. 기존 연구의 한계를 극복하기 위한 한국적 연구전략은 연구대상의 확대뿐 아니라, 정보추구가 가지는 복잡다양성과 다차원성을 포함하는 총체적인 연구접근이 필요하다. 더불어, 한국적 정보추구 현상을 설명하는 실제에 기반한 이론들을 개발할 필요가 있다.

Researches based on the pattern of planned behavior holds that the three variables of entrepreneurial attitudes, subjective norms, and perceived behavior control influence each other and influence entrepreneurial intentions respectively. However, there are also different, even conflicting research conclusions that continue to emerge. Researches based on the pattern of alertness, believe that profit opportunities and individuals' pursuit to truth are the driving forces. Many scholars have demonstrated the impact of individual entrepreneurial alertness on entrepreneurial intentions. However, as an exogenous causal agent, profit opportunities have a logical problem: if there are no other assumptions, the mere existence of opportunities does not adequately explain entrepreneurial alertness. To address this gap, this study considered samples from mainland China, where entrepreneurial activities are very active currently, to test the role that entrepreneurial alertness is assumed to play in the planned behavior model. The results show that the three dimensions of alertness, individually partly intermediate the influence of entrepreneurial attitude on entrepreneurial intention, the influence of subjective norms on entrepreneurial intention, and that of perceived behavior control on entrepreneurial intention. This article studied the production of entrepreneurial intention by integrating the two patterns of planned behavior and alertness through empirical analysis, and opened up a new field for subsequent research on entrepreneurial intention.

게임플레이 행동분석은 개발자가 설계한 게임레벨에 대한 플레이어의 경험을 게임레벨 디자인 단계에 적용하기 위해 필요하다. 플레이어의 경험수준에 따라 차이를 보이는 플레이행동을 분석하는 방법은 크게 수치적 데이터를 기반으로 한 컴퓨팅적 접근과 휴리스틱 분석기법을 통한 HCI적 접근으로 연구되어 왔다. 본 논문에서는 FPS게임의 레벨디자인 패턴에 대한 플레이어의 행동을 분석하기 위해 2가지 분석방법의 장점을 복합적으로 활용하여 12종의 주류행동을 코드화 하고 5종의 행동패턴으로 단순화 하였다. 또한 게임플레이 시간에 따른 행동패턴의 흐름을 직관적으로 비교하기 위해 최적화된 시각화방법을 제시하였다.

This paper presents a stochastic driver behavior modeling framework which takes into account both individual and general driving characteristics as one aggregate model. Patterns of individual driving styles are modeled using a Dirichlet process mixture model, as a non-parametric Bayesian approach which automatically selects the optimal number of model components to fit sparse observations of each particular driver's behavior. In addition, general or background driving patterns are also captured with a Gaussian mixture model using a reasonably large amount of development data from several drivers. By combining both probability distributions, the aggregate driver-dependent model can better emphasize driving characteristics of each particular driver, while also backing off to exploit general driving behavior in cases of unseen/unmatched parameter spaces from individual training observations. The proposed driver behavior model was employed to anticipate pedal operation behavior during car-following maneuvers involving several drivers on the road. The experimental results showed advantages of the combined model over the model adaptation approach.

The need for long-span members increases gradually in recent years, which makes issues not only on ultimate strength but also on excessive deflection of horizontal members important. In building structures, the post-tension methods with unbonded tendons are often used for long-span members to solve deflection problems. Previous studies on prestressed flexural members with unbonded tendons, however, were mostly focused on the ultimate strength. For this reason, their approaches are either impossible or very difficult to be implemented for serviceability check such as deflection, tendons stress, etc. Therefore, this study proposed a flexural behavior model for post-tensioned members with unbonded tendons that can predict the initial behavior, before and after cracking, service load behavior and ultimate strength. The applicability and accuracy of the proposed model were also verified by comparing with various types of test results including internally and externally post-tensioned members, a wide range of reinforcement ratios and different loading patterns. The comparison showed that the proposed model very accurately estimated both the flexural behavior and strength for these members. Particularly, the proposed model well reflected the effect of various loading patterns, and also provided good estimation on the flexural behavior of excessively reinforced members that could often occur during reinforcing work.

We present a novel process to fabricate three-dimensional (3D) metallic patterns from 3D printed polymeric structures utilizing different hygroscopic swelling behavior of two different polymeric materials. 3D patterns are printed with two different polymers as cube shape. The surface of the 3D printed polymeric structures is plated with nickel by an electroless plating method. The nickel patterns on the surface of the 3D printed cube shape structure are formed by removing sacrificial layers using the difference in the rate of hygroscopic swelling between two printing polymer materials. The hygroscopic behavior on the interfaced structure was modeled with COMSOL Multiphysics. The surface and electrical properties of the fabricated three-dimensional patterns were analyzed and characterized.

Customer behavior pattern discovery is the fundament for conducting customer oriented services and the services management. But, the composition, need, interest and experience of customers may be continuously changing, thereof lead to the difficulty in refining a stable description of their consistent behavior pattern. This paper presented a new method for the behavior pattern discovery from a changing collection of customers. It was originally inspired from the swarm intelligence of ant colony. By the adaptive clustering, some typical behavior patterns which reflect the characteristics of related customer clusters can extracted dynamically and adaptively.

게임에서 인공 지능은 주로 NPC(Non Player Character)와 적의 행동 패턴을 결정하거나 길 찾기에 사용된다. 이러한 인공 지능을 구현하는 경우에 FSM(Finite State Machine)과 플로킹(Flocking) 방법이 사용된다. FSM 방법에서는 상태 개수에 따라 NPC의 행동 개수에도 제한을 받는다. 상태 개수가 너무 적은 경우 플레이어들이 쉽게 NPC의 행동 패턴을 알 수 있으며 너무 많은 경우에는 구현이 복잡하게 된다. Flocking 방법에서는 리더의 결정에 따라 NPC들의 행동이 결정되기 때문에 NPC들의 이동 패턴이나 공격 방향을 쉽게 플레이어들이 알 수 있다. 본 논문에서는 이 문제를 개선하기 위하여 동물의 세력 투쟁 행동(공격, 위협, 의례적인 보여줌, 기피, 복종)들을 NPC에 적용하는 것을 제안하고 이를 Unity3D 엔진을 이용하여 구현한다. 이 논문은 실제감 있는 NPC 인공 지능 제작에 도움을 줄 수 있다.
