This study examines longitudinal patterns of financial kin support and welfare given to single mother families using life table techniques. Drawing on the 1985-1993 Panel Study of Income Dynamics(PSID), I followed 560 single mothers from the time they began a single motherhood spell. About 30 percent of these single mothers received financial support from relatives, and 40 to 50 percent received AFDC and Food Stamps, respectively. Results indicate that kin support is more likely to be given in a transitional period and tends to decrease over time. In comparison, receiving welfare appears positively time-dependent.

Nowadays, ethical consumers are increasing and they consider social values such as worker's human rights, environment and animal's welfare as key criteria in purchasing products. This study focused on the academic and practical research of ethical consumption, in which the needs and interests are now growing globally. This study addressed the concept, trend and practices of ethical consumption as well as seeking methods to support and promote ethical consumption. It examined the concept and types of ethical consumption from the perspective of the philosophy on ethical consumption. Ethical consumption was defined as a behavior that intended to improve the environment and the welfare of people and animals by purchasing products produced according to sound ethical principles and avoiding products that are made through the exploitation or the damage of people, animals and the environment. It also dealt with the practices of ethical consumption such as the fair trade movement, Clean Clothes Campaign, boycott, local food movement, animal's welfare movement. In conclusion, I suggested that consumers, companies, governments, and NGOs should make an effort to promote ethical consumption.

We propose a new method of masking cloud-affected pixels in satellite ocean color imageries such as of GLI. Those pixels, mostly found around cloud pixels or in scattered cloud area, have anomalous features in either in chlorophyll-a estimate or in water reflectance. This artifact is most likely caused by residual error of inter-band registration correction. Our method is to check the pixel-wise 'soundness' of the spectral water reflectance Rw retrieved after the atmospheric correction. First, we define two spectral ratio between water reflectance, IRR1 and IRR2, each defined as RW(B1)/RW (B3) RW (B3) and as RW (B2)/RW(B4) respectively, where $B1{\sim}B4$ stand for 4 consecutive visible bands. We show that an almost linear relation holds over log-scaled IRR1 and IRR2 for shipmeasured RW data of SeaBAM in situ data set and for GLI cloud-free Level 2 sub-scenes. The method we propose is to utilize this nature, identifying those pixels that show significant discrepancy from that relationship. We apply this method to ADEOS-II/GLI ocean color data to evaluate the performance over Level-2 data, which includes different water types such as case 1, turbid case 2 and coccolithophore bloom waters.

Monthly-mean aerosol parameters derived from the 1998-2004 SeaWiFS observations over East Asian waters are analyzed. SeaWiFS GAC Level 1 data covering the Northeast Asian area are collected and processed by the standard atmospheric correction algorithm released by the SeaWiFS Project to produce daily aerosol optical thickness (AOT) and ${{\AA}}ngstr{\ddot{o}}m$ exponent imageries. Monthly mean AOT and ${{\AA}}ngstr{\ddot{o}}m$ exponent values are extracted from the daily composite images for six study areas chosen from the surrounding waters of Japan. A slight increasing trend of ${{\AA}}ngstr{\ddot{o}}m$ exponent is found and interpreted as about 4-5% increase in submicron fraction of aerosol optical thickness at 550nm. Two cloud screening methods, including the standard cloud masking method of SeaWiFS and the one based on the local variance method, are applied to the SeaWiFS data processing, in an attempt to inspect the influence to the observed statistical uptrend which probably induced by different cloud mask algorithms. The variability comes from the different cloud masking algorithms are discussed.

This paper proposes a soft-remote-control (soft-remocon) system based on EMG signals for the Intelligent Sweet Home. The proposed system is applied to Intelligent Sweet Home which was developed to help the independence living of the elderly and physically handicapped individuals. The goal of proposed system is to control home-installed electronic devices such as TV, air-conditioner, curtain and lamp in Intelligent Sweet Home using EMG signals. Features such as VAR and DAMV having good separability performance are selected for pattern classification. FMMNN is adopted as a pattern classifier. Classification results are allowed to a developed remote control module and then corresponding infrared pulses can operate home-installed electronic devices. We concluded that EMG as an input interface for home-installed electronic devices in Intelligent Sweet Home.

The major purpose of this study is to investigate the actual condition of elementary school, nursery school, social welfare facilities providing after-school child care programs and to suggest new after-school program which is focused on social and emotional development for children of dual-earner couples. The cases of current after-school programs in Seoul and Gyeonggi area were analyzed. The results are as follows. First, it was showed Hat elementary school' child care programs after school were designed for speciality-aptitude education during 3-4 hours. Second, nursery school's programs were showed to instruct children in homework and make up learning and were operating until late evening. But the nursery school fee is more expensive than the other facilities. Third, social welfare facilities have a variety of program than elementary school and nursery school. But the program still consist of homework, supplementary lessons, speciality education etc. These facilities have too much students, compared to the teachers

Purpose: The purpose of this study was to analyze death attitudes of students majoring In the human service area, such as nursing science, education, and social welfare. Method: The Q-methodology which provides a method of analyzing the subjectivity of each item was used, The 38 selected Q-statements from each of 42 subjects were classified into a shape of normal distribution using a 9 point scale. The collected data was analyzed using a QUANL PC program. Result: Four types of death attitudes for research subjects in nursing, education, and social welfare areas were identified. Type I is fatalistic admission, Type II is pursuit of existential life, Type III is uncertainty of life after death, and Type IV is separation-connection between life and death. Conclusion: The results of the study indicate that different approaches of death educational programs are recommended based on the four types of death attitudes.

Monthly mean data of ${\AA}ngstr{\ddot{o}}m$ exponent and Aerosol optical thickness (AOT) from Sea-viewing Wide Field-of-view Sensor (SeaWiFS) measurements over the East Asian waters were analyzed. Increasing trend of the satellite-derived ${\AA}ngstr{\ddot{o}}m$ exponent from 1998 to 2004 was found while AOT mean was observed stable during the same period. The trend of ${\AA}ngstr{\ddot{o}}m$ exponent is then interpreted as increase in fraction of small aerosol particles to give quantitative estimates on the variability of aerosols. The mean increase is evaluated to be $4{\sim}5%$ over the 7-year period in terms of the contribution of small particles to the total AOT, or sub-micron fraction (SMF). Possibilities of the observed trend arising from the sensor calibration or algorithm performance are carefully checked, which confirm our belief that this observed trend is rather a real fact than an artifact due to data processing. Another time series of SMF data (2000-2005) estimated from the fine-mode fraction (FMF) of Moderate Resolution Imaging Spectroradiometer (MODIS) supports this observation yet with different calibration system and retrieval algorithms.

The preparation of single-phase $CuLaO_2$ with delafossite-type structure by means of the solid-state reaction method was investigated using X-ray diffraction. The results showed that notwhistanding the fact that there was a trace of metallic copper, nearly single-phase $CuLaO_2$ was obtained by using $La(OH)_3$ as a lanthanum source and by firing the mixed powder with nonstoichiometric composition ratio of $La(OH)_3:Cu_2O=1:1.425$ in a vacuum at 1273 K for 10 h. The measurement of electrical conductivity and Seebeck coefficient showed that $CuLaO_2$ thus obtained was a p-type semiconductor and had a Seebeck coefficient of approximately $70{\mu}V/K$.

Animal welfare has become a growing concern affecting acceptability of agricultural systems in many countries around the world. An earlier Judeo-Christian interpretation of the Bible (1982) that dominion over animals meant that any degree of exploitation was acceptable has changed for most people to mean that each person has responsibility for animal welfare. This view was evident in some ancient Greek writings and has parallels in Islamic teaching. A minority view of Christians, which is a widespread view of Jains, Buddhists and many Hindus, is that animals should not be used by humans as food or for other purposes. The commonest philosophical positions now, concerning how animals should be treated, are a blend of deontological and utilitarian approaches. Most people think that extremes of poor welfare in animals are unacceptable and that those who keep animals should strive for good welfare. Hence animal welfare science, which allows the evaluation of welfare, has developed rapidly.
