In order to set up the basic environmental control systems which the new concept greenhouses have to equip, greenhouse characteristics, environmental management and control systems in domestic glasshouses and plastic houses were investigated and analyzed comparatively. Survey results on the width, length, eaves height, and the number of spans etc. showed that glasshouses were bigger than plastic houses significantly. New concept greenhouses claim to be plastic houses, but it will be reasonable to follow the specifications of the glasshouse. Specifications to be applied to new concept greenhouses were proposed as follows; hot water heating systems, aluminum screens as the thermal curtain, evaporative cooling systems, roof vents on the ridge, circulation fans, $CO_2$ enrichment, hydroponic systems, and automatic irrigation control systems. Environmental measurement systems for the indoor and outdoor temperature, humidity, light, wind speed and indoor $CO_2$ concentration have to be fully equipped. The automatic control system has to be as a complex environmental control system, not a single item control system. Also, for stable dissemination, domestically producing complete greenhouse control system should be made as soon as possible.

The purpose of this study was to examine the effects of the self-growth group counseling program on the self-concept and the interpersonal relationships of depressed children in elementary school. A total 20 children who were screened by CDI criteria participated in this study, these students were randomly assigned to the experimental group(N=10) and the control group(N=10). The self-growth group counseling programs were implemented for ten week period. The research hypothesis were as follows: 1-1 : The scores on the self-concept measure of the experimental group received the self-growth group counseling program will be higher than the control group. 1-2 : The post-test scores on the self-concept measure of the experimental group received the self-growth group counseling program will be higher than the pre-test scores. 2-1 : The scores on the interpersonal relationships measure of experimental group received the self-growth group counseling program will be higher than the control group. 2-2 : The post-test scores on the interpersonal relationships measure of the experimental group received the self-growth group counseling program will be higher than pre-test scores. 3-1 : The scores on CDI of the experimental group received the self-growth group counseling program will be lower than the control group. 3-2 : The post-test scores on CDI of the experimental group received self-growth group counseling program will be lower than pre-test scores. The results of the study were as follows: First, the scores of the self-concept and the interpersonal relationships measures of the experimental group students appeared to be higher than the control group. However among the self-concept measure, the score of the emotional self showed no statistically significant differences between the groups. Second, within the experimental group, the scores of the self-concept and the interpersonal relationships measures of the post-test appeared to be higher than the pre-test. Third, the scores on CDI measures also showed significant mean differences between the experimental group and the control group, and between the pre- and post-tests. These findings suggested that the self-growth group counseling program interventions were functioned as for improving the self-concept and the interpersonal relationships, and for decreasing the depressed level of children. The implications and limitations of the study were discussed, and the suggestions for further researches were made.

The current status of Canadian research on rotor-based actively controlled technologies for helicopters is reviewed in this paper. First, worldwide research in this field is overviewed to put Canadian research into context. Then, the unique hybrid control concept of Carleton University is described, along with its key element, the "stiffness control" concept. Next, the smart hybrid active rotor control system (SHARCS) projected's history and organization is presented, which aims to demonstrate the hybrid control concept in a wind tunnel test campaign. To support the activities of SHARCS, unique computational tools, novel experimental facilities and new know-how had to be developed in Canada, among them the state-of-the-art Carleton Whirl Tower facility or the ability to design and manufacture aeroelastically scaled helicopter rotors for wind tunnel testing. In the second half of the paper, details are provided on the current status of development on the three subsystems of SHARCS, i.e. that of the actively controlled tip, the actively controlled flap and the unique stiffness-control device, the active pitch link.

This study presents an effective stiffness-based optimal technique to control quantitatively lateral drift for 3-D steel frameworks subject to lateral loads. To this end, the displacement sensitivity depending on behavior characteristics of 3-D steel frameworks is established. Also, approximation concept that can preserve the generality of the mathematical programming and can efficiently solve large scale problems is introduced. Resizing sections in the stiffness-based optimal design are assumed to be uniformly varying in size. Two types of 30-story frames are presented to illustrate the features of the Quantitative lateral drift control technique proposed in this study.

Resourcefulness was analyzed by Walker and Avant's method to make a theoretical framework for nursing. Also, the appropriate Korean terminology was identified.“Resourcefulness”means the ability to use internal and external resources to eliminate or to control stress. '자원동원성' is chosen to be the most appropriate term to reflect the concept of resourcefulness. Upon the concept analysis, availability, controllability, confidence, and self-instruction were identified as the defining characteristics of resourcefulness. Contrary to other work, "availability" means the ability to use the social resources as well as the internal cognitive-behavioral resources. “Controllability” means the ability to delay or control immediate gratification of one's needs or to divert one's own mood in order to solve problem. "Confidence" is the self-efficacy belief in one's control ability. "Self-instruction" is the cognitive ability to instruct oneself positively. Resourcefulness is learned by active experience, vicarious experience, and formal or informal instruction, and it is cued in the presence of a stressful situation or a need for change. As a result of the use of resourcefulness, the target behavior performed immediately and ultimately improve the quality of life or adaptation. Therefore, it is necessary to develop the instrument including the defining attributes identified in this study. Also, it is necessary to simultaneously analyze the related concepts of self-efficacy, self-control, and self-regulation for appropriate use.
