Ginkgo leaves, which have been known as medical materials, were selected as new natural dyes in this study, in which it was examined whether they have the function of UV-blocker or not. Cotton, linen & Hanji(Korean traditional paper) were dyed with Ginkgo. Al, Cr, Cu, Fe and Sn were selected as mordants. UV-blocking rate of dyed samples was measured after dyeing and mordant treatment. The results of this study are as follows. First, most surface color of dyed samples was yellow except that Hanji mordanted with Cu was yellowish red. Second, dyeing repetition had positive correlations with K/S values of cotton ($r=.\;758^{**}$), linen ($r=.\;500^*$) and Hanji ($r=.\;819^{**}$), because K/S values were increased according to dyeing repetition. Third, solar UV-blocking rates had positive correlations with dyeing repetitions (p<0.01), because UV-blocking rates had increased according to dyeing repetition. Fourth, UV-blocking ability of Hanji was highest among samples, as UV-blocking rates of cotton and linen dyed after 3 dyeing repetition were up to 93%, Hanji's values were up to 98%. Therefore, it was proven that Ginkgo extracts used in this experiment as dyestuff have excellent dyeing ability and high UV-blocking ability. It is hoped that this work will lead to further research to confirm the physiological effects when human wear the clothes made from Hanji.

The purposes of this study were to estimate the effect of related factors such as cultural values and individual characteristics to consumer attitude, and furthermore to estimate the effect of consumer attitude and related factors such as price perception and individual characteristics to consumption behavior(expenditure) of food away from home. To do this, the data was collected from college students and a 2 step approach by using LIMDEP program was applied to estimate the structural equation model. The results of this study were as follows: 1) Consumer attitude toward food away from home was found to be significantly influenced by some cultural values such as health, sensibility, socially responsible consumption and religion, and individual characteristics such as sex and pocket money. If they perceived more positively about the value of health, sensibility and religion, they would be likely to have more positive attitude, while they perceived more negatively about the value of socially responsible consumption, they would be likely to have more negative attitude. In addition, if they were females and had much more pocket money, they would be more likely to have more positive attitude. 2) Expenditure of food away from home was found to be significantly influenced by age and pocket money, while consumer attitude did not have a significant impact on expenditure of food away from home at the second stage in the structural equation model. It might imply that consumption behavior of food away from home for college students would be more constrained by individual characteristics such as sex and economic capital.

In search for a method of evaluating the cardiopulmonary function. 74 male and 33 female volunteers ages $18{\sim}25$ were subjected to this study The subjects walked on a treadmill at speed of 2,4,6 and 8km/hr with 0,5,10,15,20 and 25% grade of inclination, respectively, for a measurement of heart rate and oxygen-pulse. Heart rate was measured every 5 seconds at resting state and during walking by telemetric method using Heart Checker 108 System (Senoh Co., Japan). Oxygen concentration was measured by Douglas bag method collecting expired air for 5 minutes at rest, and for 2 minutes at the end of each walking exercise. Oxygen concentration in an expired air was analyzed with Orzat gas analyser and expressed in terms of STPD. Oxygen-pulse was defined as an amount of oxygen consumed at every heart at a cellular level. The followings were the results obtained from this study. 1. Mean values of oxygen-pulse at resting state was $3.1{\pm}0.11ml/beat$ in male and $2.5{\pm}0.87ml/beat$ in female, respectively. 2. Mean values of oxygen-pulse during treadmill walking were increased in proportion with the load of exercise, namely, the speed and grade of inclination, from minimum of 7.1ml/beat upto maximum of 18.2ml/beat in male and from minimum of 4.2ml/beat upto maximum of 12,7ml/beat in female. 3. Both linear and logarithmic regressional relationships between oxygen-pulse and speed of walking and grade of inclination were observed in both sexes. Predicted values of oxygen-pulse by logarithmic regressional formula on speed and on grade of inclination were better coincided with the measured values than those predicted by the linear regressional formula.

In this work, we compared the characteristics of three benthic biotic indices (BPI, AMBI, BIBI) which indicates the health condition of benthic communities in Masan Bay, Korea where anthropogenic impacts have been concentrated. Also we evaluated the usefulness of these benthic indices and some problems if they were applied to the Korean coastal waters. For this we used the macrozoobenthos data collected using van Veen grab ($0.1\;m^2$) at 21 sites in Masan Bay in February and August 2004. Based on the BPI values, two stations in the inner bay were found in a very hard polluted condition and three stations in the middle bay were also in a highly polluted condition. Only one station located in the bay mouth was in a normal condition. The inner bay stations showed very high AMBI values (${\geq}5.0$), indicating a highly polluted condition. The bay mouth station was assessed in a moderately polluted condition. The overall BIBI values in Masan Bay were in the range between 1.0 and 3.0. The inner bay stations showed low BIBI values (${\leq}2.0$) in the severely degraded condition. The bay mouth station with high BIBI value over 3.0 was assessed as a normal condition. All three benthos indices showed that macrozoobenthic communities in the inner bay were in a seriously polluted condition all year round, and macrobenthic faunas in the bay mouth seemed in a bad healthy condition (slightly polluted) based on AMBI during summer season. These three benthic biotic indices showed the similar assessment result, and thus we consider that each of them is a useful tool for the assessment of coastal benthic ecosystems under the organic enrichment in sediment.

This study surveyed the actual status of reclamation areas in South Pyongan Province, North Korea, using satellite images and literature to survey the creation date, area, and length of the embankment of the reclamation areas. The reclamation areas in South Pyongan Province were created in three stages, with the first stage completed in the late 1970s or early 1980s, the second stage in the late 1980s or early 1990s, and the third stage in the 2000s. The total area of the reclamation areas is 105,570 hectares. The land cover of the reclamation areas is as follows: agriculture (50.5%), saltern (29.5%), water bodies (13.6%), foreshore (12.4%), grasslands (3.0%), bare land (0.4%), facility (0.1%), and forests (0.1%). The study also found that the NDVI values of the reclamation areas vary depending on the location. The NDVI values of the Gwiseong and Namyang reclamation areas are low, while the NDVI values of the Samcheonpo and Jigdongbaedali reclamation areas are high. The study found that the NDVI values of the reclamation areas are correlated with the land cover of the reclamation areas. The study's findings can be used to understand the development direction and regional characteristics of the reclamation areas in South Pyongan Province. The study's findings can also be used to develop policies and plans for the sustainable development and utilization of the reclamation areas in South Pyongan Province.

The purpose of this study was to identify the longitudinal mediating effects of peer attachment on the relationship between psychological school environment and children's sense of community. Data on 1,088 children were obtained from the 10^th, 11^th, and 13^th Panel Study on Korean Children in the 3rd 4th, and 6th grades. The data were analyzed using descriptive statistics, Cronbach's α, Pearson's correlation, a latent growth model, and a multivariate latent growth model. All analyses were conducted in SPSS 25.0 and AMOS 23.0. The principal results were as follows. First, children's peer attachment gradually decreased over time. Moreover, individual differences existed in the initial values and rates of change. Second, the psychological school environment in the 3rd grade positively influenced children's initial peer attachment, which then exerted a positive impact on children's sense of community in the 6th grade. Second, the psychological school environment in the 3rd grade negatively influenced children's rates of change, which also exerted a positive impact on children's sense of community in the 6th grade. Finally, the initial value and rates of change of peer attachment were significant mediating effects of the relationship between the psychological school environment in the 3rd grade and children's sense of community in the 6th grade. The findings highlight the necessity of creating a psychological school environment that develops peer attachment and a sense of community among children.

Purpose: To investigate the behavioural factors of the health promotion for caregivers based on a socio-ecological model. Methods: This study was a cross-sectional descriptive study using a self administered questionnaire. The survey was conducted in 219 people chosen through convenient sampling between September and December 2008. The collected information included general characteristics, individual, interpersonal, community, policy level. Results: For the statistical analysis, the t-test was used for the health promotion according to the general characteristics and to each level of the socio-ecological model, by assessing the high and low values and dividing them into mean points. The influence elicited by different health promotion factors was determined using the hierarchical multiple regression. At the individual level, the factors influencing health promotion in caregivers included perceived seriousness, perceived benefits, and self efficacy. Social support was important at interpersonal level, and the use of community resource was relevant for the community level. We found no statistically significant factors relating to the policy level. Conclusions: In conclusion, the socio-ecological models seems appropriate for explaining health promotion and its associated factors in caregivers. We suggest that, for caregivers, strategies should be developed for their social support and to offer information about how to use community resources in relation with factors relating to the individual level.
