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.

사회범죄는 갈수록 다양화 광역화 전문화 지능화 무차별화 되어가는 양상을 보이고 있다. 사회가 발전하고 국민소득이 향상될수록 사회갈등요인과 범죄가 줄어들 것이라는 예측과는 달리 오히려 범죄의 양상도 사회발전과 더불어 더욱 다양화 전문화되면서 발전되어가는 경향을 보이고 있다. 이러한 현상은 사회발전과 범죄의 비례적 관계로 설명되어질 수 있고, 이는 자본주의의 발달과 사회의 발전이 밀접한 연관성을 갖기 때문으로 분석된다. 이에 따라 본 연구는 양자 간의 상관관계에 대해 역사적인 과정을 통한 실질적인 검증과 사실관계의 규명을 논하고 있다. 따라서 본 연구의 내용은 크게 세부분으로 나누어서 분석하고 있다. 첫째, 산업화의 진행과정에서 나타나는 범죄의 유형 및 행태와 이에 대한 사회적인 구조를 사회학적인 관점에서 분석하고 있다. 둘째, 산업사회 이후의 정보화 시대가 도래되면서 나타나는 새로운 범죄의 모습을 사회적으로 분석하고 있다. 마지막 단락에서는 사회의 변동에 따른 범죄의 행태적 변화에 대한 전반적인 분석을 하고 있으며, 사회변동은 결국 범죄의 변화를 초래한다는 상관관계를 입증하고 있다.

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.

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.
