The purpose of this study is to investigate the effects of research project program of science process skills and science-related attitudes for high school students. This study were accompanied by 72 junior students of G High School who were reorganized as students whose research subject was closely related to chemistry. These students went through 28 periods of 14 sessions of research project program, were tested before and after the study on their science process skills and science-related attitudes. A simple questionnaire afterwards to get their thoughts on this program, was surveyed. The results are as follows. First, the research project program was effective in the science process skills (p<0.01). There was a statistically meaningful difference in the subcategory of deduction, setting up hypotheses, finding variables, building experiments, graphing and interpreting data. Although there was an increase in the average scores of prediction, operant definition, and generalization factors, it was not statistically meaningful (p>0.05). Second, the research project program showed an increase in the post-test of the science-related attitudes but was not statistically meaningful (p>0.05). In terms of subcategoty, the social importance of science, criterion of scientists, application of scientific attitude, and enjoyment of science classes were statistically meaningful (p<0.05). Third, according to the survey of research project program, there was an increase in creating a research problem and solving it by oneself as well as in participating with other teammates to solve a problem. But the most difficult thing was when the experiment failed during the research was processing. The curiosity and interest, towards objects around all lives and science classes after the program done, were increased.

다중 프로젝트 관리가 요구되고 생산 활동(Activity)에 대한 공정이 반복, 연계 형태로 진행되는 프로젝트에서는 Activity에 대한 공정을 반복 입력하거나, 공정을 단계별로 관리하는 방법에서 공정별로 부하를 분석해야 하는 일은 매우 어려운 작업이다. 본 논문에서는 프로젝트에 수반된 Activity 정의와 프로젝트 공정에 대한 정의를 기준으로 Activity에 대해서 연결 공정을 자동 생성하고 공정별로 일정 및 자원관리를 유기적으로 유지하고 또한 세부 공정별로 일정 및 자원 계획 수립이 가능하며, 해당 공정에 대한 부하 분석을 실시간으로 제공할 수 있다. 그리고 계획 대비 실적 분석 등 프로젝트 진행 관리에 드는 시간과 비용을 향상하고, 프로젝트 진행할 때 발생할 수 있는 제반 문제점을 예측하여, 필요한 양의 자원 배분을 효과적으로 수행할 수 있는 프로젝트 관리시스템을 제시한다.

This paper defines a 3D full core neutronics benchmark which is based on the NuScale small modular reactor (SMR) concept. The paper provides a detailed description of the NuScale-like core, a list of expected outputs, and a reference solution to the benchmark exercises obtained with the Monte Carlo code Serpent. The benchmark was developed in the framework of the Euratom McSAFER project and can be used for verification of computational chains dedicated to 3D full-core neutronics simulations of water cooled SMRs. The paper is supplemented with a digital data set to ease the modeling process.

The human oral cavity contains a highly personalized microbiome essential to maintaining health, but capable of causing oral and systemic diseases. Thus, an in-depth definition of "healthy oral microbiome" is critical to understanding variations in disease states from preclinical conditions, and disease onset through progressive states of disease. With rapid advances in DNA sequencing and analytical technologies, population-based studies have documented the range and diversity of both taxonomic compositions and functional potentials observed in the oral microbiome in healthy individuals. Besides factors specific to the host, such as age and race/ethnicity, environmental factors also appear to contribute to the variability of the healthy oral microbiome. Here, we review bioinformatic techniques for metagenomic datasets, including their strengths and limitations. In addition, we summarize the interpersonal and intrapersonal diversity of the oral microbiome, taking into consideration the recent large-scale and longitudinal studies, including the Human Microbiome Project.

Rural amenity resources are damaged without organized management infra. National rural resources institute perform the project of developing rural amenity infra techniques from 2005 to 2009 targeting 1,230 eup-myun rural community. There are many resource surveying project in national level. For avoiding duplicated investment, clear definition of rural amenity and essential surveying items are needed. In this study, concept of rural amenity and relation with resource are considered and 10 rural amenity resource tables and items considering management, accessibility, and amenity period are developed. Finally, developed tables and items are compared with items in previous developed surveying system.

As rural landscape is considered important elements of rurality, there are many concerns about management and conservation. Rural development administration have performed rural amenity resources survey project in South Korea from 2005 for verifying states and efficient management of rural amenity. There are some problems about ambiguous definition of rural landscape range and data overlap. In this research, we reviewed rural amenity resources survey focusing rural landscape and analysized elements of 50 complex landscape resources in 2008 rural amenity selection 100. Finally, we suggested landscape viewpoint resource table in place of rural landscape because it can minimize data overlap in survey project.

Information Technology is becoming ubiquitous. Our lifestyle is changing due to this digital revolution. Many researchers had been working on exploring the meaning and ways to realize the comfortability in physical sites. With the appearance of huge amount of Web sites, which provide a variety of services like electronic commerce, network game, search engines and so on, there are many researchers working on the definition of Web Usability. In this research, we go one step forward, by exploring the meaning of Web Comfortability, based on Kansei Engineering methods.
