This study examined the effect of environmental alteration and prompts on recycling behavior. An A-B-BC with a control condition design was employed. Subjects in this study were college students, professors, and employees at a university building. After a baseline phase, environmental alteration was I effect in the next phase and both environmental alteration and prompts were in effect in the final phase for the control condition. The environmental alteration consisted of providing four separation containers for the paper cups, cans recyclable paper, and the disposable on each floor in the building. The prompts consisted of providing the information about the importance of environmental preservation and how to separate the materials in the appropriate containers using an information board and pamphlets. The dependent variables were (1) the number of cans collected in can container, (2) the number of paper cups collected in cup container, (3) the rate of correct separation of cans, (4) the rate of correct separation of paper cups, and (5) the weight of disposable. The rates of correct separations of cans and paper cups were obtained by calculating the percentage of thenumber of recyclable cans and paper cups in the corresponding containers. The results indicated that environmental alteration had positive effects on all the dependent variables. Also, when the prompts were added to the environmental alteration, the incremental effect of the prompts was demonstrated. The implications and limitations of theses findings were discussed and the direction of future studies was also proposed.

This study analyzed the present uniform satisfaction, uniform satisfaction followed by physical satisfaction, attitude for uniform, purchase attitude for uniform, satisfaction for design, preference for design, and attitude for uniform alteration behavior by distributing questionnaires to high school girl students in Daejeon City. The results of the study are as follows. The study distributed questionnaires to 319 high school girl students in Daejeon City and analyzed the satisfaction factors for their uniforms. As the result, this study induced four factors. The average value of each factor appeared in order of symbolic satisfaction, management satisfaction, activity satisfaction, and aesthetic satisfaction to show that high school girl students were the most dissatisfactory in aesthetic satisfaction. When the study examined the realities of uniform alteration, it showed that 71.2% of them altered their uniforms. In the alteration of a jacket and a skirt, they altered their jackets shortly and tightly in the mass in the order of: waist measurement, jacket length, breast width, shoulder width, and girth of the chest in a jacket. For a skirt, they altered their skirts tightly as a jacket in the order of: skirt length, waist measurement, and the girth of hip.

This study is trying to analyse the correlation between the crime behavior and the social alteration or development. Capitalism reposes on economic competition, and the impact of capitalism is according to crime behavior. Then the type of crime and the diversity of crime are transformed by the social environment and the social development. So this study is divide into 3 parts. The first is the correlation between industrialized and crime. It means that the industrialized is accompanied with the urbanized and arouse a material desire, these social phenomenon are a high correlation with increase of violent behavior and the crime. The second party is explain and analyse the correlation between the information and the crime. The information causes other type crime by contrast with the industrialized age and society. If the industrialized has caused the violent behavior and the crime, the information is too clever by half and break out the crime in the companionship of innumerable unspecifiness. So, the crime of the information age is a very wide scope and casualties, especially has a concealment of crime. And the third party describe in conclusion the social alteration and the extension of crime. Social alteration or social development is according to economic development. Competitive economic development include many complication and friction in a society, these factors are expressed in various crime. In the result the occurrence and the type of crime is a high correlation between the social alteration or development.

Mineralogical and geochemical studies on gold-bearing quartz veins and wallrock from the Mugeug mine were carried out in order to investigate the variation of mineralogical composition and the geochemical behavior of elements with distance from the gold-bearing quartz veins. Gold-bearing quartz veins occur in early Cretaceous medium- to coarse-grained biotite granite. The unaltered wallrock is composed mainly of quartz, plagioclase, orthoclase, microcline, biotite and hornblende with accessory minerals of sphene and apatite. Mineralogical changes in altered wallrock around the gold-bearing quartz veins were observed as follows; 1) biotite and hornblende altered into chlorite, and next to sericite, 2) plagioclase, orthoclase and microcline altered into sericite, and 3) calcite and quartz introduced into wallrock. Contents of $K_2O$, Rb, Cs, Au, As and Sb in altered wallrock increase, whereas those of $Na_2O$, CaO, Ba, and Sr decrease with proximity to the gold-bearing quartz veins. The loss on ignition also increases with the increase of alteration mineral. The width of primary dispersion increases in order $Au=SiO_2<As=Cs=Rb<K_2O=Sb$ and $MnO<Na_2O=CaO=Ba<Sr$. The sericitization index, $K_2O/(K_2O+Na_2O)$, is an important indicator to interpret the degree of alteration at the Mugeug mine, which is more than 0.8 in strongly and moderately altered granite, 0.5~0.8 in wea altered granite, and less than 0.5 in unaltered granite. Alteration indices for major and trace elements, and the ratio of Rb/Sr are also useful to discriminate alteration zones.

Bentonite is a type of rock that has been used as a traditional mineral medicine. It has a variety of pharmacological activities, and is used in traditional Korean medicine to treat jaundice, diarrhea, and hemostasis. In modern medicine, it is used as a raw material and additive for medicines such as antacids, gastrointestinal protective agents, and laxatives. Bentonite produced in Korea was produced through diagenesis or hydrothermal alteration of tertiary volcanic debris distributed in the Pohang and Gyeongju areas. It is mainly used for industrial purposes such as papermaking, paint, civil engineering, casting, and animal feed. Recently, technology is being developed to use it in cosmetics and pharmaceuticals. In this study, the geochemical characteristics of bentonite were identified by analyzing the main components and trace elements of 40 and 21 types of bentonite produced in the Gampo Gyeongju and Yeonil Pohang area. Also it were classifed by formation envrionment of bentonite deposits in the Gampo and Yeonil. As a result of the study, bentonite from the reserch area may be cased by argillic alteraton that alkali elements are removed form basaltic rocks by hydrothermal fluids and AI-CCPI alteration indices wrere also indentified argillic alteraton. It was found that there is a correlation between the behavior characteristics of heavy metal elements (P b, Cr, As) and the hydrothermal alteration of bentonite in the reserch area.

Purpose: To investigate the degree and sources of stress which fathers of infants in NICU experience. Method: Eighty-five fathers of NICU infants at 5 university hospitals in Seoul volunteered to complete the Parental Stressor Scale for NICU (PSS: NICU) from September 1, to October 15, 2002. Result: Total perceived stress was 3.50±0.76. The highest score were in Parental Role Alteration (3.76±0.83) and Appearance and Behavior (3.65±1.04). The total perceived stress score (PSS), correlated significantly with method (t=3.50, p=.01), and route (F=5.30, p=.00) of feeding. Light & Sound correlated significantly with birth weight (F=3.39, p=.02), medical diagnosis(F=2.30, p=.03), plan of operation(t=2.50, p=.01), operation (t=3.80, p=.02), method (F=4.90, p=.003), and route (F=4.70, p=.00) of feeding. Infant Appearance and Behavior correlated significantly with birth weight (F=5.12, p=.01), plan of operation (t=2.50, p=.01), method (F=3.50, p=.01), and route (F=7.80, p=.00) of feeding. Parental Role Alteration correlated significantly with care of incubator (t=-.68, p=.03), method of feeding (F=2.80, p=.04) and education level of father (F=3.00, p=.05). Conclusion: Father with NICU infants were concerned mostly with parental role alteration and infant appearance. Nursing intervention should include fathers of NICU infants.

Recently, many urban traditional houses have been replaced by villas and apartments for the inconvenience of lifestyle. The aim of this study is to survey the present distribution condition, research the extension and alteration, focused on Korean urban traditional houses in Cheongju which is the old city in an inland area, and inquire into the behavior patterns of an aged living alone livelihood and a large household. As a result, in the typical 'ㄱ' types of central inland houses, all the rear and side parts are nearly extended except facades facing court, while the detached houses for an aged living alones and tenants have enlarged rooms, kitchen and 'Daecheong' within the existing wooden framework. We could grasp the enlargement of room, 'Daecheong', corridor, and storage in the layout of the existing house. There are so many alterations such as the stand-up kitchen and a water closet. A new extension on an old house was intensely built for tenants.

In this study, thermal-hydrological-chemical modeling for the alteration of a bentonite buffer is carried out using a simulation code TOUGHREACT. The modeling results show that the water saturation of bentonite steadily increases and finally the bentonite is fully saturated after 10 years. In addition, the temperature rapidly increases and stabilizes after 0.5 year, exhibiting a constant thermal gradient as a function of distance from the copper tube. The change of thermal-hydrological conditions mainly results in the alteration of anhydrite and calcite. Anhydrite and calcite are dissolved along with the inflow of groundwater. They then tend to precipitate in the vicinity of the copper tube due to its high temperature. This behavior induces a slight decrease in porosity and permeability of bentonite near the copper tube. Furthermore, this study finds that the diffusion coefficient can significantly affect the alteration of anhydrite and calcite, which causes changes in the hydrological properties of bentonite such as porosity and permeability. This study may facilitate the safety assessment of high-level radioactive waste repositories.

Speech synthesis coding is classified into three categories: waveform coding, source coding and hybrid coding. To obtain the synthetic speech with high quality, the synthesis by waveform coding is desired. However, it is difficult to apply waveform coding to synthesis by syllable or phoneme unit, because it does not divide the speech into excitation and formant component. Thus it is required to alter the excitation in waveform coding for applying waveform coding to synthesis by rule. In this paper we propose a new pitch alteration method that minimizes the spectrum distortion by using the behavior of cepstrum. This method splits the spectrum of speech signal into excitation spectrum and formant spectrum and transforms the excitation spectrum into cepstrum domain. The pitch of excitation cepstrum is altered by zero insertion or zero deletion and the pitch altered spectrum is reconstructed in spectrum domain. As a result of performance test, the average spectrum distortion was below 2.29%.

The purposes of this research are, first, to investigate the present condition of indoor thermal environment in winter. Second, to find out how residents' knowledge, consciousness, and behavior changed after provided with education and information of indoor climate. Finally, to reveal how this changes make alteration to their indoor environment. Thirty apartments were collected, and then divided into three groups as Control Group, Education Group, and Edu-information Group in order to conduct the purposes. Provided education and environmental information turn out to have a positive effect to residents' knowledge, consciousness, and behavior, and consequently, it leads residents to control their indoor environment more actively in some cases. Thus, it is important to provide residents with environmental education and information, and it should be conducted regularly in order to maximize the positive effect of education since it tends to decrease as time goes by.
