This paper describes the study methods of identifying forest vegetation types, based on this study, forest vegetation classification method based on vegetation index is proposed. According to reflectance data of vegetation canopy and soil line equation NIR=1.506R+0.0076 in Jingyuetan, Changchun, China, many vegetation index are calculated and analyzed. The relationships between vegetation index and vegetation types are that PVI identifies broadleaf forest and conifer forest the most easily, the next is TSAVI and MSAVI, but their calculation is complex. RVI values of different conifer trees vary obviously, so RVI can classify conifer trees. In a word, combination of PVI and RVI is evaluated to classify different vegetation types.

The objective of this study was to analyze the two contrary effects of usage habits on the acceptance of a new IT. The one is a positive one which may be caused by expertise from the repetitive usages of a current system while the other is a negative one which would be due to lock-in. For this purpose, this study suggested three hypotheses which account for not only the negative effect of the habit in current system on the intention of using a new system but also the positive moderation effects on both relationships of perceived usefulness and perceived ease of use with the intention of a new system. For the empirical tests of the hypotheses, this study surveyed acceptance of Google Docs for the users who have a habitual used word processor. The analysis by partial least square approach showed that the hypotheses were statistically supported.

In order to promote foodservice for the elderly, foodservice managers in Continuing Care Retirement Communities (CCRCs) must identify the main factors to enhance the satisfaction and behavioral intentions with food service. The purpose of this study was to investigate the relationships between relationship quality (consisting of trust, commitment, and satisfaction) and communication in the formation of elderly's behavioral intentions with food services at CCRCs. A survey was administered to residents in two CCRCs and a total of 327 residents participated. A tested structural equation model exhibited good model fit and explanatory power of the study construct. Satisfaction directly influenced word-of-mouth and service quality has an influence on commitment. Commitment was a significant determinant of behavioral intentions to eat more often in the dining room. Also, communication showed positive association with trust. The results provided strong evidence for the importance of satisfaction and communication as a consequence of relationship marketing efforts. Suggestions for future research to better understand the elderly' behavioral intention judgments were given.

Starting with the meaning of the word quality, diverse concepts connoted by the term are examined. Instead of a bathtub curve, the desirable shape of a failure rate covering the entire life of a good product, which might be called hockey-stick line, is introduced. From the hockey-stick line and the definition of reliability, two measurements are extracted. The terms r-reliability (failure rate) and durability (product life) are explained. The conceptual analysis of failure mechanics explains that reliability technology pertains to design area. The desirable shape of hazard rate curve of electronic items, hockey-stick line, clarifies that Mean-Time-to-failure (MTTF) as the inverse of failure rate can be regarded a nominal life. And Bx life, different from MTTF, is explained. Reliability relationships between components and set products are explained. Reshaped definitions of r-reliability and durability are recommended. The procedure to improve reliability and the reasons for failing to identify failure mode are clarified in order to search right solutions. And generalized Life-Stress failure model is recommended for the calculation of acceleration factor.

Understanding consumer complaining behaviors plays a key role in post-purchase satisfaction customer retention and long-term customer relationships. This research was conducted to empirically investigate 1) the taxonomy of complaining behavior 2) causes and types of clothing complaining behavior according to sex. The subjects compoed of 250 male and 358 female consuemrs. Data were colleted through questionnaires employing the critical incident methodology. The findings indicated that clothing complaining behavior was fitted well into Singh(1998)'s three-factor model(i. e. voice/private / third-party complaining behaviors) these factors explained 53% of the total variances 75.1% of male and 65.2% of female group complained of poor instruental performance. The types of complaining behaviors were no action negative word-of-mouth to friends and associates n order. Most dissatisfied consumers didn't assert positive consumer's right. Marketer should increase the accessibility of their complaint receiving mechanisms to passive customers.

Young children's speech is compared to adult-to-adult speech and adult-to-child speech by measuring durations and variability of each segment in CVC words. The results demonstrate that child speech exhibits an inconsistent timing relationship between consonants and vowels within a word. In contrast, consonant and vowel durations in adult-to-adult speech and adult-to-child speech exhibit significant relationships across segments, despite variability of segments when speaking rate is decreased. The results suggest that temporal patterns of young children are quite different from those of adults, and provide some evidence for lack of motor control capability and great variance in articulatory coordination.

This research studied the effects of music experiences on the language development of toddlers in the day care setting. Subjects were 44(23 experimental group; 21 control group) 29- to 42-month-old children. The experimental group experienced 10 weeks of music activities, including musical sense, singing, listening, playing instruments, improvisation, finger plays, movement, simple games, word-sound music games and music routines. Language development was tested by the Preschool Receptive-Expressive Language Scale(Kim et al. 2003). Significant differences were found in the receptive language development of 30- to 36-month-old and in the expressive language development of 36- to 42-month-old toddlers, respectively.

본 논문에서는 위키피디아를 이용하여 단어 사이의 유사도와 내포된 연결 단어들에 대한 탐색 기법을 제안 한다. 위키피디아에서 제공하는 API를 이용하여 두 단어 사이를 탐색함으로써, 기존 단어 사이의 유사도를 계산하는 방식보다 더 간단하고 폭 넓은 의미 집단을 포괄할 수 있다. 이는 그래프적 특성에 기반하며 그래프를 구성하는 방식으로써 동적 방식과 정적 방식으로 구성된다.

The traditional text similarity measurement methods based on word frequency vector ignore the semantic relationships between words, which has become the obstacle to text similarity calculation, together with the high-dimensionality and sparsity of document vector. To address the problems, the improved singular value decomposition is used to reduce dimensionality and remove noises of the text representation model. The optimal number of singular values is analyzed and the semantic relevance between words can be calculated in constructed semantic space. An inverted index construction algorithm and the similarity definitions between vectors are proposed to calculate the similarity between two documents on the semantic level. The experimental results on benchmark corpus demonstrate that the proposed method promotes the evaluation metrics of F-measure.

The purposed of this study is searching the characteris-tic of 'Movement' expression by the Moving experience in display space. First, the concept of 'Movement' was defined by visitor's moving experiences according to the time pass and to visual perception. Exhibit cases were analygied to fine the relationships the defined 'Movement' experience with display spaces. But, 'Movement' is related moving experience from the entrance to importance of display space, and that is picked out key word in movement expression. Consequently, two category (visual expression, expres-sion method) to regard on the space design in display space was suggested focused on the concept of 'Movement'.
