이 연구의 목적은 마인크래프트의 몰입형 게임 환경인 스퍼드빌을 디자인하여 학습자가 영어를 습득할 수 있도록 효과적으로 돕는 것이다. 마인크래프트를 사용하여 성공적인 학습 경험을 만들기 위해, 본 연구에서는 애자일 모델과 디자인 사고 접근법을 채택했다. 우선 학습자들의 요구를 분석하기 위해 광범위한 문헌 검토를 수행하였으며 이후의 분석 단계에서 수집된 자료를 바탕으로 마인크래프트 월드를 설계하고 개발하였다. 연구자들은 인지주의 학습 모델을 스퍼드빌에 적용하면 학습자가 정보를 처리하는 방법에 대한 더 많은 통찰력을 제공할 수 있고 한편으로 구성주의 및 행동주의 접근 방식을 구현하는 것이 또한 이점이 있다는 것을 알게 되었다. 마인크래프트 게임을 통하여 영어학습의 효과를 향상시킬 수 있으며 게임기반학습이 언어학습에 도움이 될 수 있는 잠재력을 확인할 수 있었다.

Process model is an integral part of software industry. Different process models are used now a days in the industry for different software projects. Process models need to be tailored to address some specific project needs. Agile models are considered as the most widely used process models nowadays. They have distinctive features and the ability to address the dynamic needs of today's software development. Extreme programming (XP) is one of the extensively used agile process model especially for small projects. Many researchers have tried to mold XP to overcome its shortcomings and for better working in specific scenarios. Therefore, many customized versions of XP process model are available today. In this paper, we are going to analyze the latest customizations of XP. For this purpose, a systematic literature review is conducted on studies published from 2012 till 2018 in renowned online search libraries. This comprehensive review highlights the purpose of customizations, along with the areas in which customizations are made, and phases & practices which are being customized. This work will serve the researchers to discover the modern versions of XP process model as well as will provide a baseline for future directions for customizations.

This paper presents an idea and framework to automate a full cycle business process management and re-engineering by integrating traditional business process management systems, process mining, data mining, machine learning, and simulation. We build our framework on the cloud-based platform such that various data sources can be incorporated. We design our systems to be extensible so that not only beneficial for practitioners of BPM, but also for researchers. Our framework can be used as a test bed for researchers without the complication of system integration. The automation of redesigning phase and selecting a baseline process model for deployment are the two main contributions of this study. In the redesigning phase, we deal with both the analysis of the existing process model and what-if analysis on how to improve the process at the same time, Additionally, improving a business process can be applied in a case by case basis that needs a lot of trial and error and huge data. In selecting the baseline process model, we need to compare many probable routes of business execution and calculate the most efficient one in respect to production cost and execution time. We also discuss the challenges and limitation of the framework, including the systems adoptability, technical difficulties and human factors.

The main purpose of this study is to identify nursing needs of parents who have hospitalized child. Research design is a descriptive survey. The subjects for the study were 79 parents who have hospitalized child at a pediatric ward of one of the general hospital attached to a university in J city. The data was collected by researchers using a structured questionnaire. The questionnaire was Likert type 5 point scale, composed of 5 categories with 61 items. The data was analyzed by SPSS/PC. The results of the study were as follows ; 1) Mean score of nursing needs of subjects were 3.93 at 2nd day of admission and 3.99 at 7th day of admission. 2) Among the categories, the highest nursing need at the End day and 7th day of admission was ‘dilect nursing’, in desending order, ‘facilities and environment’, ‘education and counseling’, ‘nursing assessment’. The lowest nursing need was ‘reference’. 3) Differences between the nursing needs of subjects at 2nd day and 7th day were as follows : (1) By categories, there was a significant difference only in the ‘reference’ categoly(t=2.74, P=.008). (2) By items, there were significant differences in items of ‘to check necessary materials(t=2.31, P=.024)’, ‘to understand family function and family relationship(t=2.12, P=.041)’, ‘to set up study room(t=2.22, P=.030)’, and ‘to mediate parent's meeting group(t=3.89, P=.000)’. The above result indicated that nursing needs of parents with hospitalized child were above average, especially very high in items about disease process, and items directly associated with treatment and nursing care. So, nurses have to focus on information about the patient's state of disease, treatment, test and procedure, and in efficiently giving direct nursing care to implement mure effective care for the hospitalized children and their parents. And some future researche is needed to identify the difference of degree of nursing needs of parents with hospitalized child according to admission duration using a different sample and a longer sampling interval.

Gait recognition can identify people's identity from a long distance, which is very important for improving the intelligence of the monitoring system. Among many human features, gait features have the advantages of being remotely available, robust, and secure. Traditional gait feature extraction, affected by the development of behavior recognition, can only rely on manual feature extraction, which cannot meet the needs of fine gait recognition. The emergence of deep convolutional neural networks has made researchers get rid of complex feature design engineering, and can automatically learn available features through data, which has been widely used. In this paper,conduct feature metric learning in the three-dimensional space by combining the three-dimensional convolution features of the gait sequence and the Siamese structure. This method can capture the information of spatial dimension and time dimension from the continuous periodic gait sequence, and further improve the accuracy and practicability of gait recognition.

A great deal needs to be learned about why and how users participate and consume information on various online sites. The design of socio-technical systems especially for promoting engagement in terms of maximum user participation is both a theoretical and real-world challenge that researchers strive to understand. At present, most of the research on the motives of Internet video users' behavior focuses on the user's "viewing motivation" and "sharing motivation", and lacks the analysis of the factors affecting users' "subscription motivation". This study will attempt to compensate for this gap. Based on the YouTube platform, we take Chinese video users as the research object and uses the "Censydiam user motivation analysis model" to make assumptions about user subscription motivation from the two levels of social needs and personal needs, using regression analysis. Validate the hypothesis and get the influencing factors that may be available in the user's subscription motivation based on the assumptions. Built on survey data from 215 respondents, the study found that Enjoyment, Vitality, Power, and Conviviality are four factors that influence user motivation.
