The success of a crowd-funding project can be attributed to various reasons, among which, backer's (also known as 'investor', or 'funder') perception of project credibility may be a salient one. The purpose of this study is to investigate the extent to which perceived project credibility can affect a backer's investment decision. We examine the factors that could influence the building of perceived project credibility by testing the proposed research model using survey data. Analysis results indicate that perceived project credibility has a significantly positive effect on backer's investment intention. Furthermore, information quality and source credibility are two key determinants of perceived project credibility. This study contributes to crowd-funding literature by enriching the list of successful factors for fund-raising with project credibility. The study also has practical implications because it explains why and how a backer's perception of project credibility can be improved.

The demand for pharmaco-economic data has increased since the introduction of positive list system for drug insurance. A survey was conducted for pharmaceutical companies, universities and hospitals to find the current states and barriers for pharmaco-economic studies in Korea. The results showed that even those who are in charge of pharmaco-economic studies at companies/universities had a limited technical expertise. Government should pay more attention to the education of the relevant manpower, and the production of national statistics needed for economic evaluation.

Over an additive abelian group G of order g and for a given positive integer λ, a generalized Hadamard matrix GF(g,λ) is defined as a gλ$\times$gλ matrix [h(i,j)] where 1$\leq$i$\leq$gλ,1$\leq$j$\leq$gλ, such that every element of G appears exactly λ times in the list h(i$_1$,1)-h(i$_2$,1), h(i$_1$,2)-h(i$_2$,2),...,h(i$_1$,gλ)-h(i$_2$, gλ) for any i$\neq$j. In this paper, we propose a new method of expanding a GH(\ulcorner,λ$_1$) = B = \ulcorner over G by replacing each of its m-tuple \ulcorner with \ulcorner GH(g,λ$_2$) where m=gλ$_2$. We may use \ulcornerλ$_1$(not necessarily all distinct) GH(g,λ$_2$)'s for the substitution and the resulting matrix is defined over the group of order g.

School Design in the future will be more important on exterior space plan. However, there is no specific definition or boundary regarding exterior space, and related regulations and guides define the essential factors only. The purpose of this study is to have a guideline for the concept of exterior space in elementary school buildings, and deducted strong and weak points by evaluating exterior space based on each business methods. A result of this study can be suggest what improvements should be made on exterior space design of elementary school buildings by comparative analysis of positive and weak points for each evaluation factors.

This study investigated emotional regulation, motive for emotional regulation and behavior problems of children. 64 boys and 58 girls in fourth grade and their mothers were selected for the subject. The children were interviewed about eight interpersonal conflict situations, while their mothers completed the CBCL(Child Behavior Check List). Major findings were as follows: emotional regulation, motive for emotional regulation and behavior problems differed according to the children's gender. Girls used more appropriate display rules for managing negative emotions, and more often, prosocial motives than boys. While girls displayed greater immature behavior, boys displayed more hyperactive and aggressive behavior. Negative emotional regulation was the most predictable variable for boy's behavior problems. Positive emotional regulation and prosocial motives were significant variables predicting girl's behavior problems. These findings implicate that emotional regulation and motive for emotional regulation are important factors in preventing behavior problems of school-age children.

Purpose: The Edinbergh Postnatal Depression Scale (EPDS) has seen widespread use in epidemiological and clinical studies. The objective of this research was to translate and to test the reliability and validity of the 10-item EDPS in Korea. Methods: Subjects were 145 women who were 6 to 10 weeks post delivery. To test reliability, the internal consistency was assessed by Cronbach's alpha coefficient. Validity testing was performed using convergent validity by Pearson's correlation. Data was gathered at 3 hospitals during Oct. 2005 after obtaining an informed consent. Result: The mean age of the subjects was 29.9 years. and the mean parity was 1.46 times. The mean EPDS score was 18.4. Reliability analysis showed a satisfactory result (Cronbach's alpha coefficient=.84). There were significant positive correlations between EPDS and Mills postnatal depression and anxiety check list scores as expected(r=.69, p<.001) and thus supported convergent validity. Conclusion: The study findings showed that the Korean version of the EPDS-10 is a reliable and valid instrument that can be used for measuring postnatal depression in Korea.

The government should establish internationally harmonious regulations for effective import and export of necessary resources to other countries. However, the use and the number of pesticides used for the same purpose on same crops are depending on the soil and the climate where the crops are grown. Therefore, if internationally harmonized standards are difficult to establish, it is mandatory to conduct a risk assessment based on scientific data to reflect the domestic situation in order to avoid trade friction or conflict between countries. The government is preparing the implementation of a more regulated PLS (positive list systme) than the existing pesticide management system for safer pesticide management reflecting the recent increasing imported food, changing dietary habits, and changing climate. In order for effectively safe and scientific management of pesticides, the government should strive to communicate with consumers properly and the perception of pesticides by consumers should also be changed.

The purpose of this study was to develop hand creams among the types of cosmetics based on domestic pumpkins grown in Yangju. Pumpkins are mostly used for cooking, but because they contain a large amount of vitamin A, they can also be used as raw materials for cosmetics to prevent skin aging. The final design was researched and developed through a graphic expression of pumpkin characteristics, a design process, and a survey on preference for differentiated packaging design. The survey targets women in their 20s and 30s who directly purchase cosmetics, and an analysis of consumers' preference for brand product decisions showed that simple and modern designs suitable for cosmetics images topped the list. In addition, it showed a positive image of cosmetics development using local agricultural products and high brand value. We present the possibility that domestic pumpkin raw materials can be applied to cosmetics and aim to develop excellent cosmetics brands through consumer preference surveys.

Commonly, in the Sensor Network that composed with multiple nodes uses Ad-hoc protocol to communicate each other. Each sensed data packets are collected by base node and processed by Host PC. But the Ad-hoc protocol is too vulnerable to Sinkhole attack, where the intruder attracts surrounding nodes with unfaithful routing information, and then performs selective forwarding or changes the data passing through it. The Sinkhole attack increases overhead over the network and boosts energy consumption speed to decrease network's life time. Since the other attacks can be easily adopted through sinkhole attack, the countermeasure must be considered carefully. In this paper, we proposed the Hop-depth algorithm that detects intruder in Sinkhole attack and colluded nodes. First, the proposed algorithm makes list of suspected nodes and identifies the real intruder in the suspected node list through the Hop-depth count value. And recalculates colluder's path information to find the real intruder. We evaluated the performance of the proposed algorithm using NS2. We compared and analyzed the success ratio of finding real intruder, false positive ratio, false negative ratio, and energy consumption.

This study was an evaluation study of AIDS education program. The purpose of this study was to clarify the education effects on AIDS for health care workers to develop a better next education program. This study was done by self reporting with a 67 items of structured questionnaire by 431 health care workers included doctors, nurses, laboratory technicians, and health educators. Data were collected at the time of completion of each AIDS education with the help of education program manager. Both the AIDS related knowledge score and the acceptance attitudes score were significantly higher in the male group, in the medical institution employer group, in the group who have met the HIV infected person, who has known the HIV positive person, and the group of laboratory technician, but the AIDS prevention intention score was statistically higher in the group of female and laboratory technician group. The post education scores of AIDS related knowledge. acceptance attitudes, and preventive intention were statistically higher than those of the preeducation. The most increased item among AIDS prevention intention list was 'I will provide the meeting between the HIV infected persons and the public (+21.9%)'. But even the decreased item among AIDS prevention intention list was 'I will advice to female not to have extra marital sexual contact to avoid AIDS(-3.1%)'. It could be concluded that the health care workers were ignorant of vertical transmission of AIDS, they were afraid of disclosing the infection status, and have less AIDS prevention intention. Therefore it is needed to take an assessment process before each new education trategy to increase AIDS related the effect of the education on AIDS.
