The historical study reveals that our ancestors had maintained a system which could produce data on population and households. The main purposes of maintaing the system at that time were taxation and conscription. At the present time, however, there are three major data sources which produce the statistics on pop-ulation and households in Korea : Civil Registration System, Resident Registration System and Popula-tion Census. These three systems are found to have some problems. there are some inherent problems in the regis-tration systems, such as problems in its coverage, accuracies in contents and timeliness in reporting the vital events and publishing the results. The population census has also non- sampling erors, such as errors in coverage, respone and non-response. Apart from the above mentioned problems, there are also conflicting problems arised from having three data sources, We can find some overlapping problems and difficulties in comparative studies. In the future, these problems should be considered for the improvement of the quality of statistics on population and household.

A study was carried out to investigate the distribution of termites at the southern part of Korea between 1995 and 1996. During the survey, termite samples were collected from the randomly selected areas. Most of thern were collected from the decayed woods in dead trees (usually in pine trees), but some were also collected from woodern walls, floors in houses, or in matured bed logs at the mushroom cultivating areas. Damage by this termite species were also observed by Kim and Hwang (1996) who investigated the insect pests of mushroom in the southern part of Korea. To control the termites, it is urgent to identify them and to conduct ecological study of termites. Thus, we firstly identified termites which were collected from the sampling areas including houses and mushrooms cultivating fields. All termite samples were identified as Reticulitermes speratus. However, there were several morphological differences among them according to the collected areas, and the samples were reexamined, identified and divided into subspecies as R. speratus kyushuensis.

The proliferation of the House Dust Mite(HDM) is affected by temperature, humidity, ventilation, etc. Measuring temperature and humidity was performed at the very location where dust samplings take place and where they live in reality together with temperature and humidity of the ambient of the room. There has been discussion over the key environment factor of HDM survival; absolute humidity or relative humidity. It seems that relative humidity is the more important determinant for the mite's survival through the analysis of previous studies. Temperature, humidity, ventilation rate and Der P1 were measured in 4 flats in London. Mite allergen was detected in every house. Levels of Der P1 varied between <100ng/g and 22,778ng/g. Flats with high relative humidity(>50%) and poor ventilation(<0.5ach) showed higher levels of mite allergen than flats with lower humidity and adequate air change rate. Questionnaire survey was conducted and the result helped to confirm the findings from monitoring of environmental factors and the dust sampling.

This study examined whether South Koreans' philanthropic behaviors were related to the factors of two theoretical frameworks. From the involvement perspective, the study argued that three types of involvement with a telethon may be linked to volunteering and charitable donation behaviors. At the collective level, collective-efficacy may also be related to such behaviors. The study asked 279 South Koreans to respond to a Web survey that used convenience sampling. Results found that after controlling for demographics and past volunteer experiences, cognitive and behavioral involvement and collective-efficacy were positively related to volunteering behaviors, but affective involvement was not related. Moreover, only behavioral involvement and collective-efficacy were positively related to charitable donation. These results suggest that researchers and practitioners for volunteering resources need to use effective programs and contents for such behaviors in order to enhance involvement and level of collective-efficacy among community members in times of disaster.

Purpose - This study is an effort to assess the role of behavioral biases in investment decision making, specifically for mutual funds, and the moderating role of the investor. Individual investment behavior is concerned with choices about purchasing various securities. However, behavioral finance disputes the concept of perfect rationality and identifies psychological factors and their impact on decision-making. Research design, data, and methodology - A survey questionnaire was designed and used to collect responses using a judgmental sampling technique from 290 investors in the Gwalior Region. Cronbach's Alpha, factor analysis, and linear regression were all used to test the influence of behavioral biases on investment decision. Results - We found that the behavioral biases have a positive impact on investment decisions. Conclusions - This study's results identified three factors influencing investor behavior(rationale, investment skills, and profit making) and four factors influencing investor decisions (profit maker, market analysis, investment plan, seller). The overall results of the study also show that there is no significant relationship between investor behavior and investment decisions by gender in the market.

The purpose of this study is the assessment of changes in the leisure patterns of users of the Eulsook-do before and after the estuary dike construction. The following survey research method was conducted to implement the study, sampling by age was carried out selectively and randomly alike. A total of 319 persons were chosen for final analysis, excluding questionnaires answered found to be inappropriate. To measure the image of the lower Nakdong River around the Eulsook-do, with advice sought from experts, researchers, through several pilot tests, developed a 24-item semantic differential scale(SDS) that has two bi-polar adjectives at each end Study of the pre- and post- construction images of the Eulsook-do located on the coast of Busan suggests the dike construction has brought about negative changes in the Eulsook-do's overall image. There can be two alternatives for improving the negative image: restoration and development.

208 yeast strains were isolated from air at El-Minia city, Egypt. Using 22 morphologi cal and physiological merkmals, these strains were identified and assignned to eight species belonging to seven genera. Rhodotorula mucilaginosa and Cryptococcus albidus were the most dominant species followed by Debaryomyces hansenii. These yeast species occurred regularly, whereas other species appeared sporadically. Rh. rubra, Saccharomyces kluyveri and Rh. aurantiaca were also isolated from the sampled air. The results of this study showed that time, hight and area of air sampling affect composition and total counts of yeast microflora in the air.
