Oil palm trunk (OPT) is a potential source of biomass for the production of biopellet. In the present research, biopellet were prepared from the meristem part of 25 years old OPT with various percentages of its bark (0, 10, and 30%). The highest biopellet durability was found for biopellet produced at $130^{\circ}C$ of pelletizing temperature with 30% bark content. Scanning electron microscopy (SEM) of biopellet showed the weak of particle bonding due to the low pelletizing pressure. The moisture content, unit density, ash content, and caloric value of OPT-based pellets were 3.55-5.35%, $525.56-855.23kg/m^3$, 2.76-3.44%, and 17.89-19.14 MJ/kg, respectively. The combustion profiles obtained by thermogravimetric analysis (TGA) seemed to be unaffected by the bark content on. Differential thermal analysis of TGA curve indicated different pyrolysis characteristic of hemicellulose, cellulose, and lignin.

As the incidence of diet-related diseases increase, much attention has been focused of traditional foods. Traditional foods are ultimately based on local foods. However, there has been little study looking into the recipes and nutritional value of local foods. Therefore, the present study was designed to standardize recipes and analyze the nutrients of some representative local foods of Cheollabuk-do Province. Their foods were Cheonju pibimpap, kongnamulgukpap, minmuljangokui, aejeotchim and aguytichim. Test recipes for each food were prepared, being based on various information obtained from personal interviews, literature surveys of restaurant recipes. Then test recepe was subjected to sensory evaluation. All characteristics of each food were judged as "satisfactory". The analysis of nutrient composition revealed that in general energy content was low whereas protein content was as high as recommended reguirement in all foods except for kongnamulgukpap. Vitamin content was generally high but contents of calcium and iron were relatively low in all foods. Cheonju pibimpap was rich in dietary fiber. Dietary fiber content of Cheonju pibimpap was 16.6g per serving size. All foods contained considerable amounts of essential amino acids. The major fatty acide were oleic acid, linoleic acid and glutamic acid, oleic acid being the highest in terms of composition ratio.ion ratio.

This paper is concerned with realistic mainpulation of content in video sequences. Manipulation of content in video sequences is one of the content-based functionalities for MPEG-4 Visual standard. We present an approach to synthesizing video sequences by using the intermediate outputs of three-dimensional (3D) motion and depth analysis. For concreteness, we focus on video showing 3D motion of an observer relative to a scene containing planar runways (or roads). We first present a simple runway (or road) model. Then, we describe a method of identifying the runway (or road) boundary in the image using the Point of Heading Direction (PHD) which is defined as the image of, the ray along which a camera moves. The 3D motion of the camera is obtained from one of the existing 3D analysis methods. Then, a video sequence containing a runway is manipulated by (i) coloring the scene part above a vanishing line, say blue, to show sky, (ii) filling in the occluded scene parts, and (iii) overlaying the identified runway edges and placing yellow disks in them, simulating lights. Experimental results for a real video sequence are presented.

Purpose: This study was performed to identify the nursing needs of home-dwelling breast cancer patients based on counseling contents. Methods: Descriptive research was conducted with content analysis. This study included 185 patients who underwent treatment for breast cancer in a tertiary hospital. The data were collected using personal counseling via telephone or face-to-face between March 2011 and July 2013. A total of 536 counseling contents were used in the analysis. Inductive content analysis was used to analyze the contents related to nursing counselling. Results: According to the results. the most frequently reported nursing needs was symptom management, followed by information needs and supportive intervention needs; symptom management needs included symptoms related to chemotherapy, daily living, surgery, and medication side effects; information needs included treatments, medication, clinical tests, and alternative therapies; and supportive intervention needs were related to emotional and social aspects. Conclusion: Our findings suggest that nursing interventions for home-dwelling breast cancer patients should be designed and provided with a consideration to these relevant nursing needs.

The purpose of this paper is to derive the categories of negative e-WOM (electronic word of mouth) via consumer review. Disclosing the details of negative e-WOM based consumer reviews has never been done before. For this reason, a content analysis was adopted to provide knowledge and understanding of the phenomenon. This paper analyzes the content of 630 consumer reviews posted on the open market internet site, www.auction.co.kr. The analysis was conducted from October 20th, 2008 to March 10th, 2009. The results indicated that the negative e-WOM based consumer reviews can be divided into two categories: the cognitive evaluation and the expression of consumer's emotion. The category of cognitive evaluation is consisted of negative e-WOM of product, negative e-WOM of service, and warning about the risk of purchasing products. The category of expressing consumers' emotion are composed of venting customers' dissatisfaction and passive response of dissatisfaction. Investigating the details of negative e-WOM has a number of implications. Most importantly, the results revealed multidimensional structure of negative e-WOM. This understanding of negative e-WOM communication allows marketers to improve products and services that better meet customers' current and future needs.

활용과 탐색을 측정하는 방법은 특허 기반의 방법, 설문 기반의 방법, 언론 기반의 방법 세 가지로 나뉜다. 다양한 방법론이 나오게 된 이유는 활용과 탐색의 정의에 대한 합의가 아직 이루어지지 않았기 때문이다. 활용과 탐색 활동은 기업이 장기적으로 행하기 때문에 언론 기반의 방법이 가장 적절하며, 이 논문에서는 세계 광디스크 라이브러리 장치 산업의 데이터를 활용하여 유효하고, 신뢰성 있는 언론 기반의 방법에 의해 활용과 탐색을 어떻게 측정하는 것인지를 보여주고자 한다.

Purpose The impact of online reviews is widely acknowledged, with extensive research focused on text-based reviews. However, there's a lack of research regarding reviews in video format. To address this gap, this study aims to explore the connection between company-sponsored product review videos and the extent of directive speech within them. This article analyzed viewer sentiments expressed in video comments based on the level of directive speech used by the presenter. Design/methodology/approach This study involved analyzing speech acts in review videos based on sponsorship and examining consumer reactions through sentiment analysis of comments. We used Speech Act theory to perform the analysis. Findings YouTubers who receive company sponsorship for review videos tend to employ more directive speech. Furthermore, this increased use of directive speech is associated with a higher occurrence of negative consumer comments. This study's outcomes are valuable for the realm of user-generated content and natural language processing, offering practical insights for YouTube marketing strategies.

4D models help construction planners to develop and evaluate construction plans. However, current analyses using 4D models are mainly visual and limit the quantitative comparison of construction alternatives. This paper explores the usefulness of extracting quantitative information from 4D models to support time-space analyses. We use two 4D models of an industry test case to illustrate how to analyze 4D content quantitatively (i.e., work space areas and distances between concurrent activities). This paper shows how these two types of 4D content can be extracted from 4D models to support 4D-based-analysis and novel presentation of construction planning information. We suggest further research to formalize the content of 4D models to enable comparative quantitative analyses of construction planning alternatives. Formalized 4D content will enable the development of reasoning mechanisms that automate 4D-model-based analyses and provide the information content for informative presentations of construction planning information.
