The purpose of this study was to develop the household analysis and diagnosis program for the enhancement of family welfare focusing on the household of middle-aged full-time housewives. From the review of related literatures, the following areas of total family life were selected ; household management, time use, housing, household materials, finance, communication and decision making. Considering that the program subjects were middle-aged full-time housewives, the preparation for elderly life and the identity as housewife, one of the healthy family members, are appended. The progresses for the development of household analysis and diagnosis program were as follows: 1. to select the useful area of family life, 2. to make the indicators which explain the status of family life, and 3. to decide the scales for the diagnosis. This program has various uses such as the development of self-evaluation program, program for various family life course. Through this program the strength and weakness of family life can be found and the planning for the enforcement of family life can be practiced.

The study is to investigate how much middle-aged male worker's life stress affect their psychological well-being. The subject group was 223 male workers aged from 40 to 59 with a wife and children. The results are as follows: 1) the middle-aged male workers perceive an economic life stress as a most stressful problem, and mostly use a 'direct-positive' coping behavior(CB) type to settle the stress among 4 stress CB types. 2) Economic life and marital stress, 'indirect-active' and 'direct-active' CB give deep effects on their life satisfaction. 3) The effecting factors on their depression are work stress, marital stress, health stress, a 'direct-passive', an 'indirect-active', an 'indirect-passive' CB and their income. In order to increase their life satisfaction and to decrease their depression, concludingly, it is most significant for them to have a strong marital relationship and actively cope with life stress.

This study aims to clarify the relationship between family policy and children's quality of life through an international comparison and to determine which family policy factors contribute to children's quality of life. The research question is "How can family policies be combined to improve children's quality of life in terms of health and economy?" It includes nine categories of family policies related to money, service, and leave. Measures of children's quality of life include low birth weight, infant mortality, and child poverty. Using the OECD Family Database, and the OECD Child Well-being Data, fuzzy-set Qualitative Comparison Analysis (fsQCA) was used among 20 OECD countries. Combinations of family policies significant to the children's quality of life were derived from the results. This study contributes to the literature by revealing the effectiveness of states' investment in family policy. In addition, the study indicates that since family policies interact with each other, those policies combine to improve children's quality of life.

This paper identifies trends in research methodology due to globalization. Context in both research and in practice and forms the key perspective for modern methodology and theory. Ecological perspectives are a necessary condition for quality global research. Human ecology researchers must advance the role of interdisciplinary and inter-functional perspectives and be open to collaborative relationships. These researchers must work in teams across disciplinary and functional boundaries. The paper discusses directions for research within the context of trends at U.S. federal agencies with applications to globalization and family life. Trends include： (a) use of diverse but rigorous methodologies； (b) recognition of the research-practice-research feedback loop；(c) primacy of context and diverse sampling; and (d) connections of research to problem solving. The terms promoted recently such as ″relationships″, ″diversity″ or ″problem-based″ are ingrained in human ecology. Key aspects for research in the next decade will be： (a) seeking diversity in sampling； (b) seeking colleagues with different perspectives； (c) incorporating meta-analysis into our work； (d) seeking meaningful results； (e) utilizing varieties of research methodologies to address our problems； and (0 understanding that practice must continually change as a function of research.

An exploration for an intelligence paradigm has been delineated. Artificial intelligence and artificial life paradigms seem to fail to show the whole picture of human intelligence. We may understand the human intelligence better by adding the emotional part of human intelligence to the intellectual part of human intelligence. Emotional intelligence is investigated in terms of composing machine as a modern abstract art. Various algorithmic composition and performance concepts are currently being investigated and implemented. Intelligent mapping algorithms restructure the traditional predetermined composition algorithms. Music based on fractals and neural networks is being composed. Also, emotional intelligence and aesthetic aspects of Korean traditional music are investigated in terms of fractal relationship. As a result, this exploration will greatly broaden the potentials of the intelligence research. The exploration of art in the view of intelligence, information and structure will restore the balanced sense, of art and science which seeks happiness in life. The investigations of emotional intelligence will establish the foundations of intelligence, information and control technologies.

Lycopus lucid us Turcz is well known as traditional Chinese medicine, and it has been shown to exhibit antiinflammatory, -allergic and -oxidative effect. However, its anti-cancer properties have not been examined yet. In this study, we investigated the effect of the methanol extract of Lycopus lucid us Turcz on anti-cancer effect in MCF-7 human breast cancer cells. Treatment of Lycopus lucidus Turcz extract induced apoptosis and inhibition of cell proliferation in dose- and time-dependent manner. Apoptosis in the MCF-7 cells was characterized with the changes in nuclear morphology; decrease of Bcl-2 and caspase-7 expression; and increase of cleaved poly ADP-ribose polymerase(PARP). Furthermore, treatment of Lycopus lucidus Turcz extract caused the down-regulation of cell cycle-related protein including, cdk4, cyclin D1 and E2F-1. These results suggest that Lycopus lucidus Turcz might have the therapeutic value against human breast cancer cells.

The sound absorption property, hand feel, air permeability and pore size of 25 kinds of traditional Korean natural wallpapers (Hanji) were measured and analyzed in this study. The sound absorption rate of Hanji became larger with increasing of frequency beginning from 3.2 kHz, reached 2 times in frequency range of nearby 4 kHz. The sound absorption rate of Hanji was increased as the permeability was lowered and the pore size was decreased. The sound absorption property of Hanji wallpaper could be improved by manufacturing process such as super calendering process.

The sound insulation capacity of a barrier is indicated by its transmission loss. In this study, the sound transmission loss of a sound barrier filled with rice-straw particles was measured by the transfer function method and a laboratory measurement method. The results of the two measurements were compared. The transmission losses measured by the two methods were similar above a frequency of 500 Hz. The loss increased greatly upon the introduction of a plywood to the sound barrier. The results of this study are expected to be used to design sound barriers for roads.
