본 연구는 만4세 유아의 인지발달이 생태체계변인에 따라 다른지를 살펴보고, 이 변인들이 유아의 인지발달을 유의하게 예측하는지, 어머니의 취업여부에 따라 상이한 예측을 보이는지를 살펴보았다. 연구대상은 한국아동패널 5차년도 자료인 만4세 유아 998명이었고, 어머니 및 교사 대상으로 질문지 조사를 실시하였다. 그 결과 만4세 유아의 인지발달은 유아성별, 모학력, 부학력, 모취업여부, 가정환경의 질, 자녀기관생활관심정도에 따라 달랐다. 자녀기관생활관심정도가 가장 큰 영향력을 가졌고, 유아성별, 가정환경의 질, 모취업여부의 순으로 인지발달에 영향을 미쳤다. 어머니의 취업여부에 따라서는 다른 양상이 나타났는데, 자녀기관생활관심정도와 성별이 공통적으로 영향력을 미쳤지만 취업모 가정에서 자녀기관생활관심정도의 영향력이 더 크게 나타났고, 가정환경의 질은 취업모 자녀의 인지발달에 대해서만 영향력을 미쳤다. 이 연구결과는 어머니의 취업여부에 따라 유아기 자녀의 인지발달을 도모하는 정책적 접근에 유용한 기초자료를 제공한다.

Home is a major living environment of children. In urban area, indoor air at home could be severely influenced by combustion sources such as vehicle exhaust and cooking. In this work, the air quality of a high-rise apartment was investigated by monitoring combustion-related air pollutants at both indoor and outdoor in winter of 2014. From 48-h continuous monitoring data, large amount of $NO_x$ was observed at the balcony of the high-rise apartment during the morning traffic hours. It deteriorated indoor air quality of the apartment. During the cooking activity, high peak episodes of ultrafine particles were seen. It was concluded that effects of vehicle exhaust and cooking activity on the indoor air of the high-rise apartment could be easily checked by $NO_x$ and ultrafine particle indicators, respectively.

Construction project is necessary element for human life to upgrade the quality and convenience. However, due to its contradictory nature to the environment conservation, environmental pollution and damage, deterioration of natural scenery, noise/vibration, water quality pollution, etc. caused in the process of construction greatly affect the environment. The purpose of this study is to propose checklist for environment management can be used in construction phase. For this, we went ahead with the research by studying the existing research related to environment-friendly construction project management both at home and abroad, investigation and analysis of environment-related laws and ordinances, and drawing the checklists for natural environment and living environment at the construction phase. As a result, we were able to compile a checklist for nine items including geological features, animals and plants, use of soil, quality of air, water, and soil, construction wastes, noise, vibration, recreation, and sceneries. The checklist is structured in 4 grades and coded so as to allow it to be developed with the use of computer system in future. We hope that the checklist presented in this study will help lead the managers at the construction phase in construction development sustainable from the perspective of environmental conservation.

This study evaluated the quality characteristics of semi-dried noodles prepared with various dry rice flours (0, 25, 50, 75, and 100%) in order to develop the most preferred noodle recipe and to increase rice consumption. Amylography measured the viscosity of composite dry rice flour-wheat flour and indicated that the gelatinization point and maximum viscosity decreased as the level of dry rice flour increased. Both L and a values for cooked noodle significantly increased as the dry rice flour increased; however the L value decreased for uncooked of noodles. Weight, volume and water absorption of cooked semi-dried noodles significantly decreased as the dry rice flour increased; however the turbidity of soup increased. Texture properties such as hardness, springiness, cohesiveness, and adhesiveness decreased as the level of dry rice flour increased. As the amount of rice flour added increased, large particles of gluten were reduced while smaller particles of starch increased by scanning electron microscopy (SEM). The color, taste, and overall preference of 75% noodles were the highest in the sensory characteristics. The results, showed that the addition of dry rice flour positively affects the overall sensory characteristics of semi-dried noodle with 75% representing the optimal level for addition.

Purpose : Community care occupational therapy is an integrated mediation method such as evaluating and mediating daily life activities, evaluating and modifying the environment, and providing information by visiting the home where the client resides. In this study, we examine the effect of implementing a community-care occupational therapy program on the levels of depression, quality of sleep, and quality of life of elderly individuals living alone. Methods : Among the users of organizations C and D located in City B, province A, South Korea, a total of 32 elderly citizens aged above 65 were chosen as the study subjects and randomly divided into an experimental group and a control group. For the experimental group, a total of 24 sessions, each lasting 60 minutes, comprising a community-care occupational therapy program and each organization's own program, were conducted, with each session conducted twice a week for a total of 12 weeks. On the other hand, those in the control group participated in the existing programs of their organizations. Changes in the levels of depression, quality of sleep, and quality of life before and after the intervention were compared using the GDSSF-K, GQOL, and GQOL. Results : Overall, the levels of depression, quality of sleep, and quality of life were found to improve among the experimental group after the intervention. In a between-group comparison of the changes before and after the intervention, the experimental group was found to exhibit a more statistically significant difference than that of the control group. Conclusion : The results obtained in this study confirm that community-care occupational therapy programs have a positive effect on the levels of depression, quality of sleep, and quality of life of elderly individuals living alone. This implies that such programs may represent an effective solution for the problems of these individuals.

Acidic air pollutants were collected to characterize indoor air quality in a residential area in the summer. All indoor and outdoor samples were measured simultaneously using an annular denuder system(ADS) in Seoul. The data set was collected from July 26 to September 11, 1997. The mean indoor/outdoor ratios measured from this study were : 0.34 for $HNO_3$; 0.91 for $HNO_2$; 0.22 for $SO_2$; 1.34 for $NH_3$; 0.78 for $PM_{2.5}(d_p$ <2.5 $mutextrm{m}$); 0.90 for $SO_{4}^{2-}$; 0.68 for $NO_{3}^{-}$ and 0.79 for $NH_{4}^{+}$. Indoor concentrations of $HNO_3$, $SO_2$ and $PM_{2.5}$ were highly correlated with the outdoor concentrations. The relationship between indoor and outdoor air is dependent, to a large extent, on the rate of air exchange between these two environments. A tracer-gas decay technique with sulfur hexafluoride ($SF_{6}$) as a tracer gas was used to estimate the air exchange of a private home in the summer. The average air exchange rate was estimated to be 23.7 hr(sup)-1. The deposition velocities for $SO_{4}^{2-}$, $NO_{3}^{-}$ and $NH_{4}^{+}$ calculated were 0.17, 0.69 abd 0.39 cm/sec, respectively.
