This study tries to categorize innovation types for social welfare organizations and investigate the level of innovation in each type in practical field. Firstly, this study scrutinizes the concept and classification's criterias of innovation. Secondly, this study reviews not only classification of innovation in profit organization but also several researches of innovation in service industry and public sectors, and finally, this study makes a suggestion of innovations' classification that is applicable for social welfare organizations. Based on this suggestion, fifteen questions are designed to ask the innovative activities in the organizations. And total 496 respondents from 116 organizations answered these questionnaire. The outcomes of this survey were substantiated by second data through converted procedures to mean value of organizations. Consquently, service innovation, administrative innovation and human resource innovation, proposed based on theoretical review, were subdivided into six categories such as service innovation, structural innovation, internal and efficiency innovation, marketing and communication innovation, external and employment innovation and evalution and mission innovation. The mean value of service(mean=14.7) and marketing innovation(mean=13.3) are higher than other type of innovations, which shows the aspect of innovative activities in social welfare organizations. Based on this result, we can get the directions of following study in investigating innovation of social welfare organization.

Purpose: The purpose of this study was to analyze papers on child rearing in Korea and to suggest future research and nursing practice directions for child rearing. Methods: An on-line search via 5 web sites yielded 201 research papers. The analysis of key concepts was based on the attributes of parenting and type of knowledge held by the parents. Results: The research papers found in the search were 27.3% experimental and 72.7% non-experimental. Among the participants, 77.0% of parents raising the child were mothers and the children were mostly young children under the age of one year. Types of knowledge related to child rearing varied widely, but explanatory knowledge (55.2%) was the most common, followed by prescriptive knowledge (30.0%) and descriptive knowledge (14.8%). For attributes of parenting, reaction to parenting (49.9%) followed by parenting behavior/practice (43.1%) was most common. Conclusion: Findings of this study indicate that further research is necessary regarding fathers and surrogate caregivers and on prescriptive knowledge for health promotion of children at different developmental stages. Also the results suggest a need for research toward developing child care policies.

The study is about the development of operating speed prediction models aimed for an evaluation of design consistency of four lane rural roads. The main differences of this study relative to previous research are the method of data collection and classification of road alignments. The previous studies collected speed data at several points in the horizontal curve and approaching tangent. This method of collection is based on the assumption that acceleration and deceleration only occurs at horizontal tangents and the speed is kept constant at horizontal curves. However, this assumption leads to an unreliable speed estimation, so drivers' behavior is not well represented. Contrary to the previous approach, speed data were collected with one and data analysis using a speed profile is made for data selection before building final models. A total of six speed prediction models were made according to the combination of horizontal and vertical alignments. The study predicts that the speed data analysis and selection for model building employed in this study can improve the prediction accuracy of models and be useful to analyze drivers' speed behavior in a more detailed way. Furthermore, it is expected that the operating speed prediction models can help complement the current design-speed-based guidelines, so more benefits to drivers as real road users, rather than engineers or decision makers, can be achieved.

This study aims to explore how the effects of the perceived social presence on trust and live chat adoption intention vary with the types of live chats in e-commerce context. As technology develops, live chat with the seller in e-commerce is rapidly replaced by AI-assisted live chat called chat-bot. However, it is not well known how the buyers perceive the difference between the chat with seller and the chat-bot. This study therefore proposes first, the perceived social presence toward the seller will influence trust and the live chat adoption. Second, the effects of social presence will be stronger when using live chat with seller than using chat-bot. To validate, we collect data from 232 e-commerce users and confirm the first proposition. However, the higher level of the social presence effect of live chat with seller is not clearly revealed. This study is expected to provide researchers and managers who are interested in AI-based chatbots with useful theoretical and practical implications.

With the advancement of autonomous vehicle (AV) technology, autonomous driving on real roads has become feasible. However, there are challenges in achieving complete autonomy due to perceptual blind areas, which occur when the AV's sensory range or capabilities are limited or impaired by surrounding objects or environmental factors. This study aims to analyze AV accident patterns and safety issues of perceptual blind area that may occur in urban areas, with the goal of developing test scenarios for Level 4+ autonomous driving. It utilized AV accident data from the California Department of Motor Vehicles (DMV) to compare accident patterns and characteristics between AVs and conventional vehicles based on activation status of autonomous mode. It also categorized AV disengagement data to identify types and real-world cases of disengagements caused by perceptual blind areas. The analysis revealed that AVs exhibit different accident types due to their safe driving maneuvers, and three types of perceptual blind area scenarios were identified. The findings of this study serve as crucial foundational data for developing Level 4+ autonomous driving test scenarios, enabling the design of efficient strategies to mitigate perceptual blind areas in various scenarios. This, in turn, is expected to contribute to the effective evaluation and enhancement of AV driving safety on real roads.

The current study analyzed the relationship between expression type of humor ads and their advertising effects and the differences in advertising effects by expression type according to temperament as categorized by the Myers-Briggs Type Indicator (MBTI). Expression type of humor was classified into arousal-, incongruity-, and superiority-type humor ads. Advertising effects were measured by consumers' cognitive, affective, and conative responses. Three ads were created based on expression type of humor. A personality type, as measured by the MBTI, was categorized into four types of temperament, namely SP, SJ, NF, NT and used as moderating variables. As a result, the advertising effects varied according to the expression type of humor advertising. Interaction effects between ad expression type and temperament on ad feeling and ad preference were also found.

본 연구에서 개발된 새로운 유형의 마이크로파 대기압 플라즈마 공진기는 전송선로 이론을 기반으로 하여 임피던스 값을 $50{\varphi}$으로 설계함으로써 장비 자체에 구조적인 매칭이 이루어지도록 구성하였다. 안정적인 마이크로파 대기압 플라즈마 발생을 위해 컴퓨터 시뮬레이션(HFSS, High Frequency Structural Simulator)을 이용하여 공진기의 반사계수, 공명주파수, 급전점 그리고 전기장을 계산하였다. 전송선로의 이론에서 구한 급전점과 실제 제작한 마이크로파 대기압 플라즈마 공진기의 급전점 값이 큰 차이가 없음을 확인하였다. 이를 바탕으로 제작한 공진기는 급전점 5.6 mm에서 공명주파수는 0.89 GHz, 반사계수는 -37.5 dB임을 측정하였고 신호가 입사되는 정도는 90 % 이상인 것을 확인하였다. 공진기에서 발생된 플라즈마는 6 W의 정도의 저 전력으로 발생되었으며 기체유량과 인가전력에 따른 플라즈마의 기체온도를 측정하고 광 방출 특성을 고찰하였다. 실제 제작한 마이크로파 대기압 플라즈마 발생장치는 생의학적 응용을 포함한 여러 넓은 분야에서 활용될 전망이다.
