Observations and video documentation of interactions between animals living in dens, cavities, and other enclosed spaces are difficult, but they play an important role in field biology, ecology, and conservation. For example, bird parents visiting nests and feeding their nestlings may provide crucial information for testing of ecological hypotheses and may easily attract attention of participants of citizen-science ecological and conservation projects. Because of the nest concealment of cavity-nesting birds, their behaviors in the nest can only be studied by using video surveillance. Professional wildlife surveillance systems are extremely expensive. Here, we describe an inexpensive video setup that can be constructed with relatively little effort and is more affordable than any previously described system. We anticipate that the relatively low cost of about 250 USD for a battery-operated system is an important feature for citizen-science type of projects and for applications in heavily populated areas where the potential for theft and vandalism may be high. Based on our experiences, we provide methodological advice on practical aspects of using this system in the field for ecological research on birds. We highlight the low cost, easiness of construction, and potential availability to a large number of observers taking part in wildlife monitoring projects, and we offer technical help to participants of such research projects.

The purpose of this study was to examine middle school students' three behavioral systemic needs for the Housing chapter in Home Economics curriculum, Through literature review, the concepts of the three behavioral systems in this study were divided into technical, interpretive and emancipatory one. The questionnaire survey method was used, The subjects were selected randomly the third grade 259 students at 6 middle schools located in Jeonju city, from December 17, 2004 to January 17, 2005, Data were analyzed by using SPSS/WIN 11.5 program. The results were as follows; 1) Average of importance which middle school students recognized was showed the interpretive behavioral system> the emancipatory behavioral system> the technical behavioral system, That of reflection of the text book was showed that the technical was same with the interpretive, and the emancipatory was a little lower value than two systems, And needs in each system were the emancipatory behavioral system> the technical behavioral system> the interpretive behavioral system, 2) Average needs were showed according to the sub-chapter of housing. 'Preservation and Repair of house' in the technical behavioral system and 'Indoor Environment and Equipment' in the interpretive and the emancipatory behavioral systems.

Recently, the evolutionary study of human psychology and behavior has undergone rapid growth, diversifying into a few distinct sub-disciplines. One fundamental issue over which researchers in Human Behavioral Ecology and Evolutionary Psychology (EP) have different views is the role of formal optimality modeling for making hypotheses and deriving predictions about human adaptations. The study of EP typically rests on informal inferences and rarely uses optimality modeling, a strategy which human behavioral ecologists have severely criticized. Here I argue that EP researchers have every reason to make extensive use of optimality modeling as its research method. I show that optimality modeling can play an integral role in identifying the functional organization of human psychological adaptations.

This study examined (1) whether romantic partners' or close friends' acceptance-rejection perceived by college students is related to their psychological adjustment indicated by hostility/aggression, dependency, negative self-esteem, negative self-competence, emotional unresponsiveness, emotional instability, and negative world view; (2) whether parents' behavioral control in childhood and romantic partners' or close friends' behavioral control perceived by college students are related to their psychological adjustment; (3) how parents' behavioral control and acceptance-rejection in childhood perceived by college students are related with each other; and (4) how romantic partners' or close friends' behavioral control and acceptance-rejection perceived by college students are related with each other. The subjects were 163 college students enrolled in universities located in Seoul or Kyungki-do in Korea. The results indicated that college students' perceptions of their romantic partners' or close friends' acceptance-rejection are related to their psychological adjustment, that college students' perceptions of their parents' behavioral control and romantic partners' or close friends' behavioral control are related to their psychological adjustment, and that college students' perceptions of parents' behavioral control are related to their perceptions of parents' hostility/aggression, indifference, and rejection and the results were the same for the romantic partners' or close friends' behavioral control and acceptance-rejection.

The purpose of this study is to investigate the relationship among mothers' parenting stress, children's emotional-behavioral problems, and development of children's play patterns. For this study, we observed 81 5-year-old children attending a kindergarten in Southern Chungcheong province. The results of this study are as follows: First, as the mothers felt more parenting stress, the children showed more emotional-behavioral problems. This means that there exists a positive relationship between two factors. Second, aggression, oppositional defiance, and attention deficit among the children's emotional-behavioral problems had a significant, negative influence on the frequency of non-play and parallel play, while they had a significant, affirmative effect on the frequency of group play. Consequently, this study found that mother's parenting stress and child's emotional-behavioral problems affect the development of child's play patterns both directly and indirectly.
